[0002] After retrieval, a stem crushing mechanism with the authorized publication number of CN208104603U includes a stem crushing roller and a rolling roller arranged on the outer periphery of the stem crushing roller. The outer peripheries of the stem crushing roller and the rolling roller are provided with racks that can mesh with each other to roll crop stems; it also includes a driving part for controlling the rotation of the stem crushing roller. The stem crushing mechanism uses the stem crushing roller and the rolling roller to crush crop stems. During the crushing process, the stem crushing roller rotates around its own rotation axis under the control of the driving part. The crop stems enter from the feeding side of the rolling roller and leave from the discharging side after being crushed by the stem crushing roller and the rolling roller.

Multiple installation grooves 8 are opened on the rotating roller 23. A crushing plate 24 is slidably installed in the installation groove 8. A spring rod 29 is connected between the crushing plate 24 and the installation groove 8. A sleeve plate 25 is slidably sleeved on the side wall of the crushing plate 24. A scraping plate 10 is slidably installed on the sleeve plate 25. A second spring 9 is installed between the scraping plate 10 and the sleeve plate 25. The sleeve plate 25 is fixedly connected to the rotating roller 23 through the connecting rod 26. A first contact block 27 is fixedly connected to the side wall of the crushing plate 24. A discharge port is opened at the lower end of the machine body 1, and a trigger plate 28 is fixedly connected to the left side of the discharge port. The motor 21 drives the rotating roller 23 to rotate through the first rotating shaft 22. The rotating roller 23 drives multiple crushing plates 24 to rotate to crush the materials entering the machine body 1. When the crushing plate 24 rotates to the discharge port below the machine body 1, the first contact block 27 is squeezed by the trigger plate 28, so that the first contact block 27 drives the crushing plate 24 to slide into the interior of the installation groove 8. During this process, the scraping plate 10 on the sleeve plate 25 scrapes and cleans the crushing plate 24 under the action of the second spring 9, so as to clean the materials adhered to the crushing plate 24, and the materials enter the collection groove 8 through the discharge port. At this time, the spring rod 29 is in a compressed state. After the crushing plate 24 rotates away from the position of the trigger plate 28, the crushing plate 24 returns to its original position under the action of the spring rod 29;

[0028] A pressing component 3 for assisting the device to crush the stalks is also installed inside the machine body 1.

[0029] The pressing assembly 3 includes: a mounting plate 31, an arc plate 32, a second contact block 33, a protrusion 34, and a second rotating shaft 35.

The position of block 23 is matched, and a belt 1 36 is fixedly connected to the rotating shaft 25. The other end of the belt 1 36 is connected to the rotating shaft 22. The rotating shaft 22 drives the rotating shaft 25 to rotate through the belt 1 36, and the rotating shaft 2 35 drives the protrusion 34 to rotate. The rotation of the protrusion 34 intermittently squeezes the contact block 23. Under the action of the spring 1 37, the arc plate 32 reciprocates left and right to squeeze the material entering the body 1, thereby increasing the force between the material and the stem crushing plate 24 and improving the stem crushing efficiency.

[0030] The feeding assembly 6 includes: a second belt 61, a third shaft 62, and a third belt 63. The feeding assembly is fixed to the machine body 1 through a mounting shell.

The third shaft 62 is connected to the third belt 63 through transmission connection. A plurality of groups of scrapers 64 are fixedly connected to the third belt 63. The first shaft 22 drives the third shaft 62 to rotate through the second belt 61. The third shaft 62 drives the plurality of groups of scrapers 61 to rotate through the third belt 63, thereby pushing the material put into the feeding assembly 6 and allowing the material to enter the machine body 1. There is no need to manually segment and chop the hemp stalks, thereby saving time and effort.

[0031] A collecting tank 7 is slidably mounted on the base 5, and a handle is fixedly connected to the collecting tank 7. The handle has a frosted anti-skid pattern structure, which can increase friction and facilitate use.

[0032] The end of the scraper 64 is a brush structure, which can increase the friction between the scraper and the hemp stalks, thereby improving the conveying efficiency of the hemp stalks.

[0033] The end of the stem-crushing plate 24 is a corrosion-resistant metal cutter, which can be used for a long time and does not need to be replaced.

[0034] In the present utility model, first, the motor 21 is started, and the hemp stalks are placed into the feeding assembly 6. The motor 21 drives the second belt 61 to operate through the first rotating shaft 22. The second belt 61 drives the third belt 63 to operate through the third rotating shaft 62, so that the third belt 63 drives the hemp stalks to be conveyed into the machine body 1 through multiple scraping blades 61. At the same time, the motor 21 drives the roller 23 to rotate through the first rotating shaft 22. The motor 21 also drives the first belt 36 to operate through the first rotating shaft 22. The first belt 36 rotates through the second rotating shaft 35, so that the second rotating shaft 35 drives the convex block 34 to rotate, and thus the arc-shaped plate 32 performs a reciprocating motion through the cooperation of the second contact block 33 and the first spring 37, presses the hemp stalks repeatedly, increases the extrusion of the hemp stalks and the stem crushing plate 24, and further improves the stem crushing efficiency of the hemp stalks in the machine body 1. When the stem crushing plate 24 rotates to the discharge port, the first contact block 27 is squeezed by the trigger plate 28, so that the first contact block 27 drives the stem crushing plate 24 to slide into the installation groove 8. During this process, the scraping plate 10 on the sleeve plate 25 scrapes and cleans the stem crushing plate 24 under the action of the second spring 9, cleans the materials adhered to the stem crushing plate 24, and enables the materials to enter the collection groove 8 through the discharge port. At this time, the spring rod 29 is in a compressed state. After the stem crushing plate 24 rotates away from the position of the trigger plate 28, the stem crushing plate 24 returns to its original position under the action of the spring rod 29, so that the adhered materials on the stem crushing plate 24 are removed and dropped, avoiding the waste of materials. At the same time, there are no impurities on the stem crushing plate 24, and the stem crushing plate 24 is always in a state of efficient cutting, thereby improving the stem crushing efficiency of the hemp stalks in the machine body.

[0035] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
