Quality Identification of Agricultural Sprayers

Agricultural sprayer is a machine that disperses liquid and a type of pesticide application machinery. It is divided into agricultural, medical and other uses (such as industrial use).
Under normal circumstances, human-driven sprayers rely on hydraulic power, that is, hydraulic pressure, to pump liquid out. Pneumatic sprayers rely on airflow to spray, and can carry out low-volume and micro-volume spraying. Compared with hydraulic sprayers, its droplets have better uniformity and smaller droplets, and can be used for drift or targeted spraying.
In the case of agricultural sprayer quality appraisal, Zhongke Testing can provide agricultural sprayer quality appraisal services.

sprayers are divided into liquid, pneumatic and centrifugal sprayers according to their working principles.
is divided into hand-held, backpack, shoulder, pedal, stretcher, cart, self-propelled, towed, suspended, etc., as well as aviation sprayers.
tractor-pulled or mounted motorized sprayer is suitable for controlling diseases and insect pests of field crops, usually spray boom type.

The supplier and the buyer signed an "Agricultural Machinery Sales and Ordering Contract". After receiving the "sprayer" involved in the case, the demander refused to pay the remaining amount and requested to terminate the contract on the grounds that the sprayer could not work properly. As a result, a dispute arose with an agricultural machinery company on the supplier's side. After the case was brought to the local court, the court commissioned a quality appraisal of the "sprayer" involved in the case.
identification analysis results:
The identification expert group discussed and comprehensively technical analyzed the relevant information, on-site investigation and inspection results of the "sprayer" involved in the case, and made the following identification opinions:
(1) The configuration and functional parameters of the fertilizer applicator were not explained in the "Instruction Manual" that came with the sprayer involved in the case, and did not meet the requirements of relevant standards. The content was contrary to common sense, or the instruction manual may be considered inconsistent with the actual product.
(2) The spreading width of the fertilizer spreader of the sprayer involved in the case cannot reach 12 meters. The expert group analyzed that it is related to the speed configuration of the gearbox of the fertilizer spreader, and there is a direct causal relationship with the low rotation speed of the fertilizer spreading plate.
