Protection and prices to buy farm machinery depends
Agricultural machinery may cause harm to human body parts , there must be protection measures. This is the national compulsory standards . Therefore , buy equipment , be sure to choose those with reliable protective measures to relieve hazards and have a warning label products . This will not only use them at ease , but also to avoid personal injury accidents. National mandatory standards , safety of agricultural products must pass a safety protection device. Like the initiation claws, fan , pulleys, PTO shaft , liquid sprayer exhaust pipe , chain drive and the knife shaft assembly parts and so have shields . Pedals should be skid plates, easily hurt in the place you want to paste the yellow or red warning signs . Throttle, Dangba other places, have a significant operation symbols. During use , if damaged safety devices , hand sprayers do not take it lightly , should be put on the purchase of new guards to avoid security risks planted .
To see prices
Select agricultural products , according to their affordability and functional needs, appropriate to compare prices. The same types of products such as the price is too low, the quality of such a machine is often difficult to guarantee. Similar products, the proposed purchase of the medium price range . Same brand , model products in the exclusion stock machine, repairing machines , under the premise compare dealer , you can choose a relatively low price products.

With a reasonable power to buy farm machinery
Power matching the power machine mainly refers to power and speed to meet the needs of mechanical support . Power is to describe how much mechanical work done per unit of time , expressed by kw ; speed is the rotational speed of the power machine shaft , commonly r / min expressed .knapsack power sprayer The size selection is based on the power machine power production machinery needs identified . If the power machine rated power selected too large, will increase investment costs , big horse cart wasting energy ; rated power if the power machine choose small, appeared with fixed or overloaded , damaged power machine , shortened life expectancy and even damage the power machine . Therefore, according to the actual needs of production machinery and working methods , through scientific calculations, in order to select the appropriate power machine power . For the province , generally small-scale farmers to choose the power machine , the selection according to the following criteria : If agricultural production machinery and the motor is a direct drive , the selected motor power should be dragged mechanical power of 1.0 to 1.1 times ; if agriculture machinery and motor is the result of belt drive , the selected motor power should be dragged mechanical power of 1.05 to 1.30 times ; engine supporting agricultural machinery should be equal to the power required 1.3 to 1.5 times. Optional powered farm machinery required speed as much as possible with the speed of the same or close , because it can be installed directly used agricultural machinery , because speed is inconsistent, in order to meet the requirements , you must refit the transmission equipment, fruit tree sprayers increase the number of charges .
If there are some agricultural households power equipment in advance , it should give full play to the role of existing power machine , in the purchase of new agricultural machinery , we should try to consider power machine capable of matching the original , except for special needs , in general, do not each machine is individually furnished one kind of power machine , so that it costs too much, management is not easy .

Four coup spring wood furniture to help you achieve pest
pring, the weather is warming, if the home with wooden furniture, be careful to start a variety of active worms, oh. The following recommended several ways to help you overcome "Zerg."
After the renovation or insect chemical sprayer spray water as much as possible, buy pure wood furniture must ensure through pest control treatment. Spring and summer, when you open the window preferably with mosquito nets.
Paint handling. Have not yet been victimized some corners, with raw tung oil, shellac or varnish coating, brush the surface of lockers, so moth isolated from the air, to achieve the purpose of moth.
Pharmaceutical treatment. When the lockers are moth damage, the available dichlorvos and water ratio of 1:5 dubbed liquid,back sprayers spray with a sprayer full, so that the liquid penetrate inside lockers, to a continuous jet 3-5 times.
Diesel rubbed. Clear the infestation has been placed in lockers at sunrise, with a brush or cotton dipped in diesel will all lockers painted again.

How hot season only reasonable use of pesticides
Safe use of pesticides has been a concern for farmers, but in the actual production but has not been brought to our attention, blind medication continues to occur, resulting in a serious waste pesticides, injury occur frequently; while for applicators is a poison , especially in the hot season, which is even more prominent. For this reason, to remind farmers rational drug use.
First, improving the utilization of pesticides.
Attention to increase adhesion agents. Outdoor use of pesticides should be selected crops resistant to rain erosion, cream and other more appropriate surface residues of these pesticides on the plants longer, whereas powder, liquid, etc. are relatively poor. Many crops, there blade surface or thick hair wax layer, such as corn, onion, ginger, taro, etc., the liquid in the hair, easy to form droplets on the wax layer, can not fully contact with the surface of plant leaves, can Silicones in pharmaceutical and other additives added to enhance the pharmaceutical effects.
Second, appropriate to reduce the concentration of drug
Most of the efficacy of pesticides as the temperature rises, the efficacy will be enhanced, so the hot season medication should be taken to minimize the amount of liquid, especially pharmaceutical hormones is particularly note the dosage weight can easily lead to injury of happen. Therefore, according to changes in temperature reasonable adjustments pharmaceutical concentrations.
Third, pay attention spray quality
In fact, during the drug crop spraying, the crop can be attached to the blade surface pesticide droplets is limited, when the pressure sprayer spray volume exceeds a certain limit, the leaves on the tiny droplets will agglomerate into large droplets and rolled down, the loss, but the blade attached to the lower amount of pesticides. General requirements for aerosol spray droplet mass distribution, high coverage to wet the surface does not drip appropriate plants, thus requiring the use of spray atomization effect, reduce the liquid waste. Note also that a comprehensive spraying, especially some of the pests prefer spawning in the dorsal damage, especially when spraying agent attention.
Fourth, a reasonable spraying to prevent poisoning
Pharmaceutical, pesticide spraying to prevent corrosion of the skin, the use of volatile pesticides must pay attention to the use of masks, while prohibiting the midday heat in summer time household sprayer spraying pesticides, spraying should be selected in the summer before 9 am or after 4 pm, to avoid injury place. Continuous application time not too long.

Water mist application conditions and requirements
A water mist extinguishing system should be refillable water containers clean and fresh water. (Commonly used industrial distilled or treated potable water)
2, the protection zone structure and the doors and windows of the fire resistance of not less than 0.50h, the ceiling of the fire resistance of not less than 0.25h. (This is to prevent the spread of fire outside the protection zone into the protection zone, thus requiring the protection zone of the wall and the doors and windows should have some fire resistance. While requiring the issuance of extinguishing fire to a period of time, building components will not be damage to ensure airtight protection zone, does not cause loss of extinguishing agent, affecting fire effect.)
3, before the start of water mist fire suppression system and the set fan, smoke machines, blowers and pipeline fire damper, smoke damper should be closed automatically. Staff confirmed after the fire should start the smoke machine smoke. (This is because to a protected area being ventilated water mist extinguishing agent release, fire extinguishing agent as soon exhaust air outflow protection zone, the protection zone to reach the design requirements of fire extinguishing agent, seriously affecting the extinguishing effect; another , fire protection zone may also spread through the air duct.)
4, water sprayer mist extinguishing system, you must cut off the fuel, combustion gases of the gas source. (This is to prevent fire expand, to prevent dilution agent discharge strength, impact extinguishing effect.)
5, the nozzle head and nozzle bottle plastic sprayer spray angle between the object of protection should not be within the scope of obstructions. (This is because the memory in the range of the jet nozzle obstruction, will seriously affect the jet effect, which affects the extinguishing effect.)
6, the protection zone should be used doors fire doors open in the direction to evacuate, and can automatically shut down. (This is to prevent the door open in case of emergency, the impact of evacuation. While requiring evacuation door can be automatically shut down, in order to facilitate the protection zone of water mist fire extinguishing water to maintain a certain strength to prevent the loss of extinguishing agent, impact extinguishing effect can be avoided for some reason the person trapped in the protection zone, from the protection zone to open the door smoothly evacuated. protection zone automatic closing doors design, emphasizing when the door is closed, on how circumstances can open from inside the protection zone.)
7, water mist fire extinguishing system equipment should be set at an ambient temperature 4-50 ℃ dedicated equipment room. (This is because the temperature is too low, the water will freeze, the temperature is too high in the tank water temperature, resulting in vaporization and heat exchange, and may have a scale affect water quality. Settings in a dedicated room is to make the fire-extinguishing system equipment to avoid being the impact of adverse weather conditions or subjected to other mechanical damage. while allowing staff to manage and maintain.)
