Abstract

The invention discloses a dead furrow on-site water taking device of a paddy field pesticide application machine, and belongs to the field of paddy rice field management machinery. The device comprises a water colleting tank, a water taking auxiliary device, a self-priming pump, a two-position three-way solenoid valve, a filter, a one-way valve, and a water tank. The water taking auxiliary device comprises an up and down heaving mechanism, a left and right swinging mechanism, and a servo driving system. Water is pumped out from the water colleting tank by the self-priming pump, and flows into the water tank after being filtered by the filter. In order to prevent the filter from being blocked, the solenoid valve is switched at fixed time, to back wash the filter. The up and down heaving mechanism realizes profile modeling on a dead furrow bottom. The left and right swinging mechanism performs flexible centering when the water colleting tank laterally offsets. The servo driving system adjusts the position of the water taking auxiliary device when the water colleting tank offsets left and right excessively. Through taking water on site in a paddy field dead furrow and filtering the water, the device can obtain clean water for pesticide mixing, and volume of a pesticide cabinet is reduced.

Description

technical field [0001] The invention belongs to the field of rice field plant protection machinery, and relates to an in-situ water intake device for a paddy field pesticide applicator. Background technique [0002] The current pesticide application machinery for paddy fields has a heavy medicine box and a high grounding specific pressure, which will cause great damage to the mud bottom of the paddy field, and it is easy to get stuck in the process of operation. The reason is mainly because the water tank is too heavy, which leads to the excessive weight of the unit. To solve this problem, water can be taken locally in the rice field, and the water can be forcibly filtered to obtain clean water, which can then be used, which can reduce the volume of the water tank, thereby greatly reducing the weight of the sprayer. However, at present, the water layer in the rice field is relatively thin, and there are many weeds and impurities on the water surface, and the operating machi...
