Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a liquid pesticide preparation and spraying device. Background Technology

[0002] Agriculture is an industry that utilizes the growth and development patterns of plants and animals to obtain products through artificial cultivation. Agriculture belongs to the primary sector, and the science that studies agriculture is agronomy. The objects of agricultural labor are living plants and animals, and the products obtained are the plants and animals themselves. Agriculture is a fundamental industry that provides support for national economic construction and development.

[0003] Agricultural liquid pesticide spraying devices require manual pre-mixing of pesticides during use. However, existing pesticide spraying devices lack precise liquid pesticide mixing mechanisms. In most cases, users add water and pesticides to the device based on subjective feeling and experience. This method cannot accurately control the amount of pesticide added, and it is easy to pour in too much pesticide during the mixing process. Excessive pesticide addition can lead to crop death. Therefore, we propose a liquid pesticide mixing and spraying device to solve the above problems. Utility Model Content

Multiple agitating rods are fixedly mounted on the drive shaft. The top end of the drive shaft extends to the top of the housing and is fixedly mounted on a rotating plate.

[0010] Preferably, the top of the cover plate has two fixing grooves, and the semi-circular plate is provided with a fixing mechanism that matches the fixing grooves.

[0011] Preferably, the fixing mechanism includes a movable groove, a movable plate, and a T-shaped fixing pin. The movable groove is formed on the bottom of the semi-circular plate, the movable plate is slidably installed in the movable groove, and a T-shaped fixing pin is fixedly installed on the movable plate. The T-shaped fixing pin is adapted to the corresponding fixing groove, and the top end of the T-shaped fixing pin extends to the top of the semi-circular plate.

[0012] Preferably, a fixing spring is fixedly installed on the top inner wall of the movable groove, and the bottom end of the fixing spring is fixedly installed on the top of the movable plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. When preparing liquid pesticides, the T-shaped fixing pin and fixing groove are used to fix and release the semi-circular plate. By rotating the semi-circular plate, it can be rotated to one side of the dosing hole, thus opening the dosing hole. The semi-circular plate can drive the sealing plate to rotate through the rotating shaft, so that the connecting hole rotates to the left side of the guide hole, thus closing the guide hole. At this time, pesticides can be added to the metering box. The amount of pesticide added can be accurately measured through the scale observation window. When the semi-circular plate is reset, the dosing hole is closed and the guide hole is opened, thus adding pesticides into the box.

[0017] 2. By manually rotating the rotating plate, the rotating plate can drive the drive shaft and stirring rod to rotate. The rotation of the stirring rod can make the pesticide and water fully mixed. The pump body can supply the prepared liquid pesticide to the spray head, and the spray head can achieve the purpose of spraying the pesticide. Attached Figure Description
