Pesticide tank structure of paddy field cart

Abstract

The invention discloses a pesticide tank structure of a paddy field cart and belongs to the technical field of plant protection and spraying devices. The pesticide tank structure comprises a tank body, a pesticide liquid buffering mechanism and a back flushing mechanism, wherein the pesticide liquid buffering mechanism and the back flushing mechanism are arranged on the tank body, multiple partition plates are arranged in the tank body, the pesticide liquid buffering mechanism comprises multiple plug holes, multiple plug blocks correspondingly matched with the plug holes, plug shafts and a telescopic air cylinder, the multiple plug holes are correspondingly arranged at the lower portions of multiple partition plates, the multiple plug blocks are fixedly connected with the plug shafts respectively, a cylinder body of the telescopic air cylinder is arranged outside the tank body, a through hole is formed in one side of the tank body, a sealing shaft sleeve is fixedly arranged in the through hole, and the ends of the plug shafts penetrate through the shaft sleeve to be connected with a piston rod of a driving air cylinder. The back flushing mechanism comprises a back flushing stirring tube. The overall strength of a pesticide tank can be improved, pesticide liquid impact can be reduced, high-low speed alternation and the stability on the uneven working ground of the plant protection cart are improved, and pesticide liquid mixing in each liquid storage tank is even.

Description

technical field [0001] The invention relates to a medicine box structure of a paddy field vehicle and belongs to the technical field of plant protection spraying equipment. Background technique [0002] During the growth of crops, they are often harmed by pests and weeds. At the slightest, local or individual plants are stunted and their growth is affected. At worst, the entire crop is destroyed, resulting in reduced or no harvest. Therefore, it is necessary to spray pesticides through plant protection spraying equipment. Prevention is more important than treatment, and diseases, insects, and weeds are eliminated before they are harmful, so as to ensure a bumper harvest. Modern agriculture tends to be large-scale production, and the scale of the land requires a larger capacity of the medicine box. The medicine box containing the medicine liquid is installed on the frame of the plant protection spraying equipment, and the medicine liquid is provided for the spray boom by con...

Problems solved by technology

[0005] The beneficial effects of the present invention are: the medicinal liquid enters into each liquid storage cavity in the casing through the opening on the top of the casing, if the liquid level of the medicinal liquid in the casing is low, it can be stretched out through the piston rod of the telescopic cylinder, and the inserting block and the inserting block The holes are separated, and the medicine liquid flows into each liquid storage chamber through the jacks on the partition. When the working environment is flat and the speed of the plant protection vehicle is uniform, the medicine box shakes little and the jacks are open, even if the medicine liquid flows through the jacks to the Each liquid storage chamber will not cause the plant protection vehicle to rollover. When the working environment is harsh, such as the uneven working environment in the paddy field, in order to avoid the plant protection vehicle from rolling over, the piston rod of the telescopic cylinder is retracted, and the plug is inserted in the corresponding position. Corresponding sockets prevent the flow of the liquid medicine in the liquid storage chamber, so that the overall center of gravity of the box will not have a large shift, and at the same time effectively reduce the impact of the liquid medicine on the box; use a partition to separate the liquid medicine in the box Although partitioning solves the problem of the impact of the liquid medicine on the box, it also brings about the problem that the liquid medicine in each liquid storage chamber is easy to precipitate, and the mixing of the liquid medicine is not sufficient and uniform; The tank is equipped with a recoil stirring tube, which can reintroduce the liquid in the outlet pipe of the tank into the liquid storage chamber by controlling the recoil valve to promote the mixing of the liquid medicine. The setting of the recoil stirring tube also plays a great role in the cleaning process of the tank , the use of recoil mixing tube is not only more convenient and quick to clean the box, but also clean the box
