Description

Technical Field

[0001] This utility model specifically relates to a multi-stage kneading and shredding structure for rapid straw decomposition, belonging to the field of straw shredding technology. Background Technology

[0002] Straw is the general term for the stems, leaves, and ears of mature crops that remain after the grains are harvested. It is mostly hollow or solid cylindrical stalks, usually between 0.5 and 2 meters in length, and is characterized by being renewable and having a high yield.

[0003] Chinese Patent (Publication No.: CN223528549U) discloses a straw shredder for rapid fermentation, comprising a support frame 1, a support frame 2, a curved pipe, and a cylinder body. The curved pipe and the cylinder body are interconnected. The support frame 1 is fixedly connected to the cylinder body, and a drive motor is fixedly installed on the support frame 2. The cylinder body is equipped with a shredding component that facilitates cleaning. This utility model, through structural improvement and optimization, utilizes the height difference between the support frame 1 and the support frame 2 to enable the straw to actively flow downwards during the shredding process, resulting in more thorough shredding. The connection between the annular groove and the shredding blade ensures that the straw does not pass through the cylinder body without gaps, further improving the shredding effect. The cover plate designed on the cylinder body allows for convenient periodic opening for internal cleaning, resulting in a more thorough cleaning and preventing residual straw from fermenting and becoming moldy.

[0004] The aforementioned straw shredder for rapid fermentation, when processing straw with fine, long fibers and high flexibility, if the cutting blade fails to completely cut the straw fibers in a single cut, the ends of the fibers are easily hooked by the blade and rotate synchronously with the blade shaft. Under the action of centrifugal force, they gradually wrap around the surface of the cutting blade, forming a dense fiber entanglement. The entanglement may also cause severe friction with the cylinder wall, generating local high temperatures, which in turn leads to phenomena such as straw carbonization and charring, and abnormal increase in particle size. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a multi-stage kneading and shredding structure for rapid straw decomposition. It includes a cylinder with a feed bend installed at one end. The feed bend and the cylinder are inclined as a whole. A gear is rotatably mounted on the outer wall of one end of the feed bend via a bracket. Racks mesh on both sides of the gear. A first connecting arm and a second connecting arm are connected to one side of each rack. Multiple cutting plates are installed at one end of the first connecting arm, and multiple backing plates opposite to the cutting plates are installed at one end of the second connecting arm. The cutting plates and backing plates are slidably connected to the inside of the feed bend. An electric push rod is also installed on the outer wall of the feed bend, and the moving end of the electric push rod is connected to the first connecting arm.

[0006] The cutting plate has a first mounting groove at one end, and a flat cutter is installed inside the first mounting groove by multiple sets of screws. The total length of the flat cutter and the cutting plate is the same as the total length of the backing plate.

[0007] The outer wall of the feed bend is provided with two sets of connecting slots. Two sets of semi-circular protective shells are inserted into the two sets of connecting slots. Both ends of the two sets of semi-circular protective shells are provided with docking plates. Screws are provided inside the multiple sets of docking plates.

[0008] The feed bend has a second mounting groove inside at the point where the backing plate and the cutting plate pass through, and a brush is installed inside the second mounting groove.

[0009] The cylinder is internally driven and installed with a shredding shaft. Multiple sets of connecting rings are equidistantly arranged on the shredding shaft. Multiple sets of insertion slots are opened around the inside of the connecting rings. Insert blocks are inserted into the insertion slots. The connection between the insert blocks and the insertion slots is fixed by screws. A shredding blade is installed at one end of the insert block.

[0010] The outer wall of the cylinder is equipped with multiple sets of support legs, and each set of support legs has a rubber pad at its bottom.

[0011] Beneficial effects: By adding a reciprocating shearing mechanism driven by gears and racks at the feeding end, the straw is pre-cut, cutting long sections of straw into short sections, thereby reducing the overall length of straw entering the cylinder, eliminating the source of long fiber entanglement, and thus reducing the risk of straw entanglement with the shredding shaft and shredding blades inside the cylinder.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4 As shown, a multi-stage kneading and shredding structure for rapid straw decomposition includes a cylinder 1. A feed bend 2 is installed at one end of the cylinder 1. The feed bend 2 and the cylinder 1 are inclined. A gear 3 is rotatably mounted on the outer wall of one end of the feed bend 2 via a bracket. Gears 4 mesh on both sides of the gear 3. A first connecting arm 5 and a second connecting arm 6 are connected to one side of each set of gears 4. Multiple cutting plates 9 are installed at one end of the first connecting arm 5, and multiple support plates 8 are installed at one end of the second connecting arm 6, opposite to the cutting plates 9. The cutting plates 9 and support plates 8 are slidably connected to the inside of the feed bend 2. An electric push rod 7 is also installed on the outer wall of the feed bend 2. The moving end of the electric push rod 7 is connected to the first connecting arm... 5. Connection; During operation, the straw is fed through the feed bend 2, and the electric push rod 7 is turned on at the same time. The moving end of the electric push rod 7 reciprocates to push the first connecting arm 5 and the connected rack 4 to move back and forth. Through the reverse meshing of the gear 3, the second connecting arm 6 moves synchronously in the opposite direction, so that the cutting plate 9 and the backing plate 8 form a shearing edge moving in opposite directions. When the cutting plate 9 and the backing plate 8 are closed, the straw is clamped between the two. The cutting edge of the cutting plate 9 cuts into the fiber layer, realizing the shearing and crushing of the straw, and forming a chopping cut, cutting long sections of straw into short sections, so as to reduce the overall length of straw entering the cylinder 1, thereby reducing the risk of straw entanglement with the cutter roller inside the cylinder 1.

[0016] Furthermore, a first mounting groove 10 is provided at one end of the cutting plate 9. A flat cutter 11 is installed inside the first mounting groove 10 by multiple sets of screws. The total length of the flat cutter 11 and the cutting plate 9 is the same as the total length of the backing plate 8. During operation, the flat cutter 11 can be quickly separated from the cutting plate 9 by removing the screws, allowing the flat cutter 11 to be replaced separately.

[0017] Furthermore, the outer wall of the feed bend 2 is provided with two sets of connecting slots 12, and two sets of semi-circular protective shells 13 are inserted into the two sets of connecting slots 12. Both ends of the two sets of semi-circular protective shells 13 are provided with docking plates 14, and screws are provided inside the multiple sets of docking plates 14. During operation, the two sets of semi-circular protective shells 13 can wrap the above-mentioned cutting components to avoid damage and potential dangers caused by the extension movement of the first connecting arm 5 and the second connecting arm 6 coming into contact with external personnel or objects. At the same time, by removing the screws, the two sets of semi-circular protective shells 13 can be quickly removed from the feed bend 2. When installing the two, the two sets of connecting slots 12 can provide positioning for the two sets of semi-circular protective shells 13.

[0018] Furthermore, the feed bend 2 is provided with a second mounting groove 15 at the through-hole of the backing plate 8 and the cutting plate 9. A brush 16 is provided inside the second mounting groove 15. During operation, the brush 16 can clean the residual debris on the surfaces of the cutting plate 9 and the backing plate 8 as they move, reducing the sticking and friction caused by material debris adhering to the surfaces of the two and the pipe wall at the through-hole.

[0019] Furthermore, a shredding shaft 17 is driven and installed inside the cylinder 1. Multiple sets of connecting rings 18 are equidistantly arranged on the shredding shaft 17. Multiple sets of insertion slots 19 are opened around the inside of the connecting rings 18. Insert blocks 20 are inserted into the insertion slots 19. The connection between the insert blocks 20 and the insertion slots 19 is fixed by screws. A shredding blade 21 is installed at one end of the insert block 20. During operation, the insert block 20 can be quickly disengaged from the insertion slots 19 by unscrewing the screws, thereby enabling the replacement of individual shredding blades 21. When a shredding blade 21 is worn or damaged, only that individual blade needs to be replaced, without replacing the entire blade shaft or connecting rings 18, thus reducing spare parts costs and maintenance expenses.

[0020] Furthermore, multiple sets of support legs are installed on the outer wall of the cylinder 1, and each set of support legs is equipped with a rubber pad at the bottom. During operation, the rubber pads can increase the friction between the bottom of the support legs and the ground, thereby improving the stability of the device.
