Description

Technical Field

[0001] The utility model belongs to the field of premixing tanks, and particularly relates to a raw material premixing tank for compound fertilizers. Background Art

[0002] The raw material premixing tank for compound fertilizers is a device used to mix various raw materials. Generally, the raw materials of compound fertilizers include main elements such as nitrogen, phosphorus, and potassium, as well as trace elements and other additives. In the premixing tank, these raw materials will be accurately proportioned and mixed evenly to ensure that the final compound fertilizer produced has balanced nutrient components. The premixing tank is usually equipped with a stirrer or other mixing equipment to ensure full mixing of the raw materials. At the same time, a wetting agent or binder can also be added to improve the stability and quality of the particles. The entire mixing process is generally carried out in a closed environment to prevent the raw materials from being polluted by the external environment. After mixing, the raw materials will be transported to a granulator or pelletizer for granulation, and finally the finished compound fertilizer is produced.

[0003] When the current raw material premixing tank is in use, it is not convenient to control the amount of materials inside the tank. When the amount of materials is large, the materials stack on each other, which will affect the stirring and mixing effect. And during the stirring and mixing process, if the materials get damp, they are likely to adhere to the inner wall of the tank, and it is difficult to clean the materials on the inner wall of the tank, which will affect the raw material mixing effect. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of the utility model is to provide a raw material premixing tank for compound fertilizers, which solves the problems that the existing raw material premixing tank is not convenient to control the feeding amount and the materials are damp and adhere to the inner wall of the tank and are difficult to clean.

[0005] In order to achieve the above purpose, the utility model provides a raw material premixing tank for compound fertilizers, which includes a tank body. Four uniformly distributed support rods are fixedly connected to the bottom of the tank body. A blanking port is fixedly connected to the lower end of the tank body. A cover plate is fixedly connected to the top of the tank body. A driving motor is fixedly connected to the top of the cover plate. The output end of the driving motor is rotatably connected to the cover plate. A rotating rod is fixedly connected to the lower end of the output end of the driving motor.

A top plate is fixedly connected to the top of the cylinder body. A blanking mechanism is arranged on the cylinder body. A cleaning mechanism is arranged on the tank body.

[0006] The principle of the present utility model is as follows: during use, the raw materials are first added into the interior of the cylinder through the feed hopper. Subsequently, the output end of the lifting motor drives the screw rod to rotate, causing the plug to perform a threaded movement.

During the stirring process, the lifting motor works intermittently. The output end of the lifting motor can drive the screw rod to rotate, enabling the threaded movement of the plug. The plug performs a reciprocating movement in the vertical direction. After the plug separates from the inner wall of the cylinder, the materials inside the cylinder can be input into the tank for mixing, realizing the intermittent addition of raw materials and avoiding excessive accumulation of materials, which may affect the mixing effect.

[0009] Through the design of the connecting piece and the scraping blade, when the driving motor drives the stirring rod to rotate, the scraping blade can rotate along the inner wall of the tank, scraping the materials adhering to the inner wall of the tank during the mixing process, avoiding the problem that the adhered materials are difficult to clean and affect the mixing effect. Moreover, the scraping blade can remain in contact with the inner wall of the tank under the elastic action of the spring, improving the cleaning effect.

The inner side wall of the cylinder is fixedly connected with a fixing rod. The top of the fixing rod is fixedly connected with a guide rod. The guide rod is fixedly connected with the top plate. The outer side of the guide rod is slidably sleeved with a sealing ring. The sealing ring is slidably connected with the guide rod. By designing the feeding mechanism, intermittent addition of materials can be realized.

[0011] Furthermore, a rotating groove is formed inside the top plate, and the output end of the lifting motor is rotatably connected inside the rotating groove. By designing the rotating groove, the output end of the lifting motor can rotate inside the rotating groove.

[0012] Furthermore, a sealing ring is rotatably sleeved outside the screw rod, and the sealing ring is fixedly connected to the plug. By designing the sealing ring, the connection between the screw rod and the plug can be sealed.

[0013] Furthermore, the cleaning mechanism includes a connecting rod. The right end of the rotating rod is fixedly connected to the connecting rod. A connecting sleeve is slidably sleeved outside the connecting rod. The right end of the connecting sleeve is fixedly connected to a connecting piece. The right end of the connecting piece is fixedly connected to a scraping piece. The scraping piece contacts the inner wall of the tank body.
