A vertical sand mill for pesticides

Abstract

This utility model relates to the field of sand mill technology and discloses a vertical sand mill for pesticides, including a fixed frame, a sand mill jar fixedly installed on the fixed frame, a drive motor fixedly installed on the top of the sand mill jar, and a conveying pipe fixedly installed on the top of the side wall of the sand mill jar. This utility model uses a rotating rod to drive the coarse powder blades to rotate and crush materials. During crushing, the materials accumulate on a screening plate. Simultaneously, the rotation of the rotating rod drives a rotating block to rotate as well. The rotating block controls the impact hammer at the top of the fixed rod to continuously impact the screening plate, causing the screening plate to vibrate and sieve small and medium-sized materials to the bottom. The rotating rod then drives the fine powder blades to further crush the falling materials, thereby improving grinding efficiency. By starting a servo motor, the telescopic end of the telescopic rod is controlled to move the base downwards, at which point the base detaches from the bottom of the sand mill jar, facilitating collection and cleaning.

Description

Technical Field

[0001] This utility model relates to the field of sand mill technology, and in particular to a vertical sand mill for pesticides. Background Technology

[0002] Vertical sand mills, also known as bead mills, are mainly composed of a machine body, main drive, disperser, feed pump, continuously variable transmission, cooling system, and electrical controller. In the laboratory, they mainly play a role in dispersing and grinding pesticides, and are widely used in the field of pesticide production.

[0003] An existing vertical sand mill for pesticide laboratories (announcement number: CN219400381U) has at least the following drawbacks: when the above device grinds, all materials are mixed together, which will cause the materials that have been ground into small particles to be over-ground, while the large particles are ground less frequently, thus reducing the grinding efficiency. In addition, the bottom of the vertical mill is flat, and the grinding blades need to be removed to clean the accumulated materials, which is very inconvenient. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vertical sand mill for pesticides.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A vertical sand mill for pesticides includes a fixed frame, on which a sand mill jar is fixedly mounted. A drive motor is fixedly mounted on the top of the sand mill jar. A conveying pipe is fixedly mounted on the top of the side wall of the sand mill jar. A feed inlet is fixedly mounted on the top left side of the conveying pipe. A base is provided at the bottom of the sand mill jar. A telescopic rod is provided at the bottom of the base. The telescopic end of the telescopic rod is fixedly connected to the bottom of the base. A servo motor is fixedly mounted at the bottom of the telescopic rod. The servo motor is fixedly mounted on the fixed frame. A slot is provided at the bottom of the sand mill jar, and the top of the base can be engaged in the slot.

[0006] As a further embodiment of this utility model, a rotating rod is provided in the middle of the inside of the sand mill jar. The top of the rotating rod penetrates the sand mill jar and is fixedly connected to the output end of the drive motor. A sieve plate is provided in the middle of the rotating rod. The sieve plate is fixedly installed on the inner wall of the sand mill jar. The rotating rod passes through the sieve plate. A coarse powder blade is provided on the upper side of the sieve plate, and a fine powder blade is provided on the lower side of the sieve plate. Both the coarse powder blade and the fine powder blade are fixedly installed on the rotating rod.

[0007] As a further embodiment of this utility model, a rotating block is provided at the lower center of the screening plate. The rotating block is fixedly sleeved on the rotating rod. A sliding groove is provided on the outer side of the rotating block. A control ring is sleeved on the outer side of the rotating block. A slider is fixedly installed on the inner side of the control ring. The slider can be movably engaged in the sliding groove. Fixed rods are fixedly installed at both ends of the outer side of the control ring.

[0008] As a further embodiment of this utility model, a limiting groove is formed on the inner wall of the fixing frame corresponding to the position of the fixing rod. Both ends of the fixing rod can be movably engaged in the limiting groove, and a spring is fixedly installed between the bottom of the limiting groove and the bottom of the fixing rod.

[0009] As a further embodiment of this utility model, impact hammers are fixedly and evenly installed at equal intervals on the top of the fixing rod.

[0010] As a further embodiment of this utility model, a screw rod is movably installed in the conveying pipe, and a control motor is fixedly installed at the top left end of the conveying pipe, with the output end of the control motor fixedly connected to the screw rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, the coarse powder blades are driven to rotate by a rotating rod to crush the material. During crushing, the material accumulates on the screening plate. At the same time, when the rotating rod rotates, it drives the rotating block to rotate as well. When the rotating block rotates, it controls the impact hammer at the top of the fixed rod to continuously hit the screening plate, causing the screening plate to vibrate and screen the small and medium-sized materials on the screening plate to the bottom. Then, the fine powder blades driven by the rotating rod will further crush the falling material, thereby improving the grinding efficiency.

[0012] 2. In this utility model, the extension end of the telescopic rod is controlled by starting the servo motor to drive the base to move down. At this time, the base will detach from the bottom of the grinding jar, and the ground material will accumulate in the base, thereby achieving the effect of convenient collection and cleaning.
