Description

Technical Field

[0001] The utility model relates to the technical field of crushing and screening devices, in particular to a plant tissue crushing and screening device. Background Art

[0002] The crushing and screening device is used to crush the plant tissue raw materials, and then collect the crushed samples after screening for extraction. The crushing and screening device consists of a box, a feed port, a motor, a stirring chamber, a rotating shaft, a cutting blade, a screen, a discharge chamber, and a collection box. The plant tissue raw materials are poured into the stirring chamber of the box from the feed port, and the motor is started to rotate the cutting blade on the rotating shaft to crush the plant tissue. After the crushed plant tissue reaches the size of the screen, it falls through the holes on the screen into the collection box in the discharge area.

[0003] The inventor discovered in his daily work that when the crushing and screening device is in use, since plant tissue contains moisture, when the cutting blade is used to crush the plant tissue, the plant tissue is destroyed and the moisture flows out. At the same time, the rotating cutting of the cutting blade generates centrifugal force, which causes the crushed plant tissue to be thrown to the inner wall of the stirring chamber, so that part of the crushed plant tissue adheres to the inner wall of the stirring chamber, thereby contaminating the plant tissue to be crushed next time. Utility Model Content

A plant tissue crushing and screening device is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a plant tissue crushing and screening device, comprising a box body, a feed port and a motor are installed on the top of the box body, a screen is slidably inserted at the right end of the box body, a stirring chamber and a feeding chamber are provided on the inner wall of the box body, a collecting box is provided on the inner wall of the feeding chamber, the output end of the motor is fixedly connected to a rotating shaft, a plurality of evenly distributed cutting blades are fixedly connected to the circular arc surface of the rotating shaft, a cleaning assembly is provided on the inner wall of the stirring chamber, a replacement assembly is provided between the screen and the box body, and the cleaning assembly includes a plurality of evenly distributed connecting rods fixedly connected to the circular arc surface of the rotating shaft, and a plurality of evenly distributed scraping rods are fixedly connected to the other end of the connecting rod.

[0006] The effect achieved by the above components is: through the cleaning component, when scraping the plant tissue attached to the inner wall of the box, the motor drives the rotating shaft to rotate, causing the connecting rod to rotate, thereby scraping the plant tissue attached to the inner wall of the box, and then the plant tissue falls onto the screen. The staff disassembles the screen to remove the plant tissue, thereby preventing the plant tissue attached to the inner wall of the box from affecting the plant tissue crushed next time.

[0007] Preferably, square grooves are provided on both sides of the scraper rod, and the inner walls of the square grooves are slidably connected with extrusion plates.

[0008] The effects achieved by the above components are: by arranging the square groove and the extrusion plate, the extrusion plate moves to scrape off the plant tissue attached to the scraping rod.

[0009] Preferably, a spring 1 and a round rod are fixedly connected to one side of the extrusion plate, and the other end of the spring 1 is fixed to the scraper rod.

[0010] The effect achieved by the above components is: by setting the spring 1, the extrusion plate is reset.

[0011] Preferably, a mounting groove is provided at the upper end of the scraper rod, a cam is rotatably connected to the inner wall of the mounting groove, and a round rod is slidably inserted into the inner wall of the square groove.

[0012] The effect achieved by the above components is that the cam in the mounting groove rotates automatically, thereby squeezing the round rod and pushing the extrusion plate.

[0013] Preferably, a gear ring is fixedly connected to the top of the inner wall of the box body, and a gear is fixedly connected to the top of the cam, and the gear ring and the gear are meshed.

[0014] The effect achieved by the above components is that when the cam rotates, the gear rotates on the gear ring, thereby causing the cam to rotate on its own.

[0015] Preferably, the replacement component includes a circular groove opened on one side of the screen, the inner wall of the circular groove is slidably connected to a plug rod, the plug rod is inserted into the box body, and one side of the plug rod is fixedly connected to a pull rope.

[0016] The effect achieved by the above components is: when it is necessary to replace the screen with a different mesh number, pull the pull rope to completely retract the rod in the circular groove, separate the rod and the box, and then install the new screen.

[0017] Preferably, one end of the insertion rod is fixedly connected to a second spring, and the other end of the second spring is fixed to the screen.

[0018] The effect achieved by the above components is: by setting the second spring, the insertion rod is reset.

[0019] Preferably, the pull rope passes through the screen, and the other end of the pull rope is fixedly connected to an operating panel.

[0020] The effect achieved by the above components is: dragging the operating panel causes the pull ropes on both sides to be pulled to control the movement of the insertion rods on both sides.

[0021] In summary, the beneficial effects of the present invention are as follows:

[0022] In the utility model, through the cleaning component, when scraping the plant tissue attached to the inner wall of the box, the motor drives the rotating shaft to rotate, causing the connecting rod to rotate, thereby scraping the plant tissue attached to the inner wall of the box, and then the plant tissue falls onto the screen. The staff disassembles the screen to remove the plant tissue, so as to avoid the plant tissue attached to the inner wall of the box affecting the plant tissue to be crushed next time. It solves the problem that because the plant tissue contains moisture, when it is crushed with a cutting blade, the plant tissue is destroyed and the moisture flows out. At the same time, the cutting blade rotates and cuts to generate centrifugal force, so that the crushed plant tissue is thrown to the inner wall of the stirring chamber, so that part of the crushed plant tissue is attached to the inner wall of the stirring chamber, thereby causing contamination of the plant tissue to be crushed next time.

After the crushed plant tissue reaches the size of the screen 6, it falls into the collection box 7 in the unloading area through the holes on the screen 6. When scraping the plant tissue attached to the inner wall of the box body 1, the motor 5 drives the rotating shaft 8 to rotate, so that the connecting rod 21 rotates, thereby scraping the plant tissue attached to the inner wall of the box body 1, and then the plant tissue falls onto the screen 6. The staff disassembles the screen 6 to remove the plant tissue, so as to avoid the plant tissue attached to the inner wall of the box body 1 affecting the plant tissue crushed next time. By setting the square groove 23 and the extrusion plate 27, the extruder The plate 27 moves to scrape off the plant tissue attached to the scraper 22. By setting a spring 1 210, the extrusion plate 27 is reset, and the cam 25 in the mounting groove 24 rotates by itself, so that the round rod 26 is extruded, thereby pushing the extrusion plate 27. When the cam 25 rotates, the gear 28 rotates on the gear ring 29, so that the cam 25 rotates by itself. When it is necessary to replace the screen 6 with a different mesh size, the pull rope 34 is pulled to fully retract the insertion rod 32 in the circular groove 31, so that the insertion rod 32 and the box body 1 are separated, and then the new screen 6 is installed. By setting a spring 2 33, the insertion rod 32 is reset, and the operating plate 35 is dragged to pull the pull ropes 34 on both sides to control the movement of the insertion rods 32 on both sides.
