Description

Technical Field

[0001] This utility model relates to the field of cotton harvesting technology, specifically to an automatic control device for the concentration of cotton defoliant. Background Technology

[0002] Cotton is a plant of the genus *Gossypium* in the family Malvaceae. It includes upland cotton, herbaceous cotton, and tree cotton. It is an annual herb or subshrub with sparsely covered long soft hairs on its twigs. The seeds are separate, oval, and have long white cottony hairs and short grayish-white cottony hairs that are not easily detached.

[0003] Before cotton harvesting, defoliants need to be sprayed to cause the leaves to fall off, which facilitates mechanized harvesting. Traditional manual formulation requires adding the required raw materials into a mixing tank and then adding them to the reaction vessel in the correct amount. However, the raw materials should not be stored for a long time after being exposed to air in the mixing tank, which leads to waste if not used up. This reduces the efficiency of defoliant formulation and increases production costs, so improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide an automatic control device for the concentration of cotton defoliant, so as to solve the problems of easy waste and high production cost in the preparation of cotton defoliant mentioned in the background art.

[0006] Preferably, the material bins are distributed in a circular pattern with equal intervals around the inner wall of the fixing frame, the top of the material bins has an opening, and the bottom of the material bins has an inclined structure.

[0007] Preferably, a sealing cap is inserted inside the top opening of the material hopper, and a pressure gauge is connected to the top of the sealing cap.

[0008] Preferably, the outer wall of the fixing frame has multiple sets of sliding grooves, and each set of sliding grooves has a slider inserted inside.

[0009] Preferably, one end of the slider is fixedly connected to the support plate, and the support plate and the fixed frame are slidably connected.

[0010] Preferably, a stirrer is rotatably connected inside the reactor, and a stirring motor is fixedly connected to the top of the reactor, with one end of the stirring motor shaft connected to the top of the stirrer.

[0011] Preferably, the bottom of the reactor is connected to a discharge pipe, and a discharge valve is provided on the discharge pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This device can realize automatic proportioning and vacuum storage of raw materials, thereby ensuring the usage time of raw materials and avoiding waste of raw materials.

[0014] (2) This device uses multiple material barrels connected to the outer wall of the reactor to store various raw materials. By setting a vacuum pump on one side of the material barrel, the material barrel can be vacuumed after the raw materials are added, thereby achieving vacuum storage of the raw materials, ensuring the next use of the raw materials and avoiding waste.
