Description

Technical Field

[0001] The utility model relates to the technical field of pesticide application, in particular to a liquid medicine mixing and spraying device during the pesticide application process. Background Art

[0002] Crop pesticide application is an important link in agricultural production. Before pesticide application, it is necessary to observe the types of crop pests and diseases, and accordingly select appropriate liquid pesticides for spraying. Since crops are usually affected by multiple pests and diseases at the same time, it is usually necessary to mix and spray multiple pesticides with different drug effects to achieve the simultaneous control of multiple pests and diseases.

[0003] Existing liquid medicine mixing and spraying devices are mostly composed of a mixing tank and a spraying pipe. When mixing medicines, it is usually necessary to manually operate to mix various liquid medicines in the mixing tank according to the ratio, and then spray them through the spraying pipe. First of all, manual operation is time-consuming and laborious, and has a certain degree of danger. It is not convenient to accurately control the medicine ratio, and it can only be sprayed in a single direction and at a single height at the same time. Secondly, the mixing method of the medicine is single, and after the medicines are mixed and then sprayed, it is easy to cause the ideal proportion of the sprayed liquid medicine due to uneven distribution of the medicine, affecting the pesticide application effect. In addition, the medicine is directly sprayed out of the mixing tank, and the impurities generated during the medicine mixing process enter the nozzle with the liquid medicine, which is easy to cause blockage and affect the spraying effect.

The upper cover can not only prevent external impurities from entering the dispensing hopper to ensure the purity of the medicine, but also avoid the splashing of the medicine, which is safe and reliable.

[0008] Furthermore, the lower end of the storage tank is in an inverted cone shape protruding from the center towards the dosing tube. A storage tube is connected above the storage tank, and a tube plug is provided above the storage tube.

[0009] Based on the above features, the inverted cone shape design is conducive to the complete outflow of the liquid medicine, reducing residues. The storage tube is convenient for replenishing the liquid medicine, and the tube plug can effectively seal to avoid the pollution of the liquid medicine.

[0010] Furthermore, the support structure includes a support plate. The four corners of the lower part of the support plate are connected to the mixing tank through the first support rods. The dispensing tube is fixedly connected to and penetrates through the support plate. A fixing ring is fixedly connected to the outside of the storage tank, and the fixing ring is connected to the support plate through a plurality of second support rods.

[0011] Based on the above features, it can stably support the dispensing tube and the storage tank, ensuring the stability of the device.

[0012] Furthermore, the medicine outlet tube is arranged close to the bottom surface of the mixing tank.

[0013] Based on the above features, it can fully extract the uniformly mixed liquid medicine, avoid extracting the unfully mixed part, and also avoid the waste caused by the remaining medicine in the mixing tank.

[0014] Furthermore, a filter screen is provided in the middle of the filter tube. The dosing tube and the dispensing tube, and both ends of the filter tube and the medicine outlet tube and the spraying tube are hermetically connected.

[0015] Based on the above features, the filter screen can effectively filter impurities, and the hermetic connection can prevent the leakage of the liquid medicine, ensuring the tightness and safety of the device.

[0016] The advantages of the present utility model compared with the prior art are as follows: A flow control valve is provided on the medicine adding pipe below each medicine storage tank, which can accurately control the addition amount of each medicine according to needs, realizing precise automatic batching. The medicine outlet pipes in multiple directions are detachably connected to spraying pipes of various heights, which can adapt to the spraying requirements of different heights and directions, realizing precise and efficient spraying. The spiral pipe can slow down the descending speed of the liquid medicine, thereby realizing the preliminary mixing of the liquid medicine flowing into each medicine storage tank in the pipeline, which is beneficial to improving the medicine mixing efficiency. The stirrer can work during the spraying process to ensure that the medicine is always sprayed evenly. The detachable filter pipe can effectively filter the impurities generated during the medicine mixing process, prevent the impurities from entering the nozzle and causing blockage, and ensure the smoothness of spraying.
