Description

Technical Field

[0001] The invention belongs to the technical field of grinding equipment, and in particular relates to a plant material grinding and processing equipment. Background Art

[0002] In the fields of chemical industry, medicine, food and agriculture, grinding of plant raw materials is a common processing step, which aims to break plant tissues (such as roots, stems, leaves, fruits, etc.) into fine particles or powders to increase their surface area for subsequent extraction, mixing or reaction. Traditional grinding equipment (such as ball mills and hammer mills) rely on mechanical impact or shear force to break plant fibers, but plant cell walls contain cellulose, hemicellulose, lignin, etc., which leads to long grinding time, high energy consumption, and difficulty in achieving uniform grinding. In addition, conventional methods make it difficult to accurately control the particle fineness, and coarse particles are mixed with ultrafine powders, affecting the subsequent extraction rate or preparation uniformity. In addition, the hardness and moisture content of different plant raw materials (such as seeds, leaves, rhizomes) vary greatly, and the existing equipment lacks adaptive adjustment functions, resulting in excessive or insufficient grinding of some raw materials.

[0003] The Chinese patent document with publication number CN208642771U discloses a Chinese medicine crushing and screening mechanism, including a crushing device and a screening device, the screening device includes a base and a crushing shell, the base supports the crushing motor, the crushing shell is provided with a feed port, the feed port is connected to the feeding hopper, the crushing shell is connected to the first discharge pipe, a static grinding disc and a dynamic grinding disc are provided in the crushing shell, the static grinding disc is fixedly installed in the crushing shell by positioning bolts, and the dynamic grinding disc is coaxially connected to the transmission shaft through a mechanical seal. The crushing and grinding of Chinese medicine relies on the relative movement of the toothed inclined surfaces of the dynamic grinding disc and the static grinding disc, wherein the dynamic grinding disc rotates at a high speed and the static grinding disc is stationary, so that the material between the toothed inclined surfaces is subjected to a great high shear force and friction force, thereby enhancing the crushing effect.

[0004] In the above patent solution, the plant material slides between the moving grinding disc and the static grinding disc by its own gravity, but the roots, stems and leaves of the plants are easily entangled with each other, preventing the plant material from sliding from the feeding bin into the grinding bin. In addition, since the plant fibers of the plant material entering the grinding bin are often tough, the plant fibers often adhere to the grinding teeth on the moving grinding disc, which also prevents the plant material from sliding further down. If the plant material slides slowly, the grinding time will be prolonged, which directly affects the working efficiency of the grinding equipment. Summary of the invention

[0005] In order to overcome the technical problems in the prior art that plant raw materials are entangled and knotted with each other and adhere to the grinding teeth, which will cause the plant raw materials to slide slowly, the grinding time is long, and the working efficiency of the grinding equipment is low. One purpose of the present invention is to provide a plant raw material grinding and processing equipment, by arranging a plurality of grinding discs with opposite rotation directions in the grinding bucket, the plant raw materials in the grinding bucket are moved in two directions for grinding, and the interaction forces between the raw materials move each other, thereby preventing the raw materials from adhering to the grinding teeth of the grinding disc. At the same time, a bevel disc is arranged on the upper end of the grinding disc, which can not only cut the raw materials, but also push the raw materials downward, accelerate the falling speed of the raw materials, and thus improve the grinding efficiency.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a kind of plant raw material grinding and processing equipment, comprising a feeding hopper, the lower end of which has an opening; a grinding hopper, the grinding hopper is arranged at the lower part of the feeding hopper, and the grinding hopper is connected with the feeding hopper; a grinding part, the grinding part is arranged in the grinding hopper in a conical shape, and the gap between the outer wall of the grinding part and the inner wall of the grinding hopper gradually decreases from top to bottom; wherein, the grinding part comprises at least two grinding discs rotatably connected in the grinding hopper; two adjacent grinding discs are pressed against each other and rotate in opposite directions; a bevel disc is rotatably connected to the upper end of the grinding part in the grinding hopper; the upper part of the bevel disc is inclined to the side away from its rotating axis.

[0007] In the prior art, the grinding disc always rotates in the same direction in the grinding bucket, and the filaments of the plant material are easily embedded in the grinding teeth of the grinding disc. The juice of the plant material is often sticky, and the plant material adheres to the grinding disc and cannot slide down smoothly, which will reduce the grinding efficiency of the processing equipment. The grinding disc with opposite movement directions will cause the plant material in the grinding bucket to move in opposite directions in layers. The mutual force of the plant material will prevent the plant material from always rotating with the grinding disc, that is, prevent the plant material from adhering to the grinding disc, ensure that the plant material slides down smoothly, and thus improve the grinding efficiency.

[0008] The bevel disc and the lower end of the grinding bucket form a shear force, which can switch the entangled and knotted plant materials. At the same time, the inclined surface of the bevel disc can also push the plant materials to feed toward the grinding part below, thereby accelerating the grinding speed.

[0009] Furthermore, it includes a receiving tray, which is arranged directly below the grinding hopper; a discharging hopper, which is arranged at the lower end of the receiving tray and communicated with the receiving tray; a material shifting ring, which is rotatably connected to the inner bottom end of the receiving tray; wherein a flexible filter screen with a drooping middle portion is arranged in the discharging hopper; a rib is arranged on the edge of the flexible filter screen; fixed rods are respectively arranged at both ends of the flexible filter screen, and the fixed rods are arranged on the inner wall of the discharging hopper; a wave rod is rotatably connected to the bottom of the flexible filter screen in the discharging hopper, and the wave rod can selectively move the uppermost part of the flexible filter screen to above the fixed rod, and move the uppermost part of the flexible filter screen from one side to the other side.

[0010] The ground powder may clump due to humidity, stickiness and other reasons. The movable flexible filter can break up the clumps to a large extent, allowing the powder to pass through the flexible filter smoothly. The residue that cannot pass through the flexible filter will be pushed to one side as the flexible filter moves, and then discharged from the residue outlet.

[0018] Specifically, the upper end of the uppermost grinding disc is provided with a non-cylinder; the lower end of the beveled disc is provided with a non-circular opening; the non-circular opening and the non-cylinder are non-circular with the same cross-section.

[0019] Specifically, support rods are respectively provided at both ends of the wave rod, and the ends of the support rods are rotatably connected to the inner wall of the discharge hopper.
