Description

Technical Field

[0001] This utility model relates to the field of straw silo technology, and in particular to a straw enzymatic hydrolysis square silo discharge anti-blocking device. Background Technology

[0002] During the enzymatic hydrolysis of straw, the straw needs to be temporarily stored and transported through a silo. However, the straw's loose fiber structure and tendency to clump together often cause blockages at the silo discharge stage.

[0003] Traditional straw silos lack targeted anti-clogging mechanisms. When straw gathers towards the discharge port under gravity, it easily entangles and clumps together, causing blockages in the discharge channel. Furthermore, current technologies rely solely on simple stirring to clear blockages inside the silo, resulting in limited anti-clogging effectiveness. This makes it difficult to adapt to the processing needs of straw with varying moisture content and density, and fails to fundamentally solve the technical problem of straw silo discharge blockage.

[0004] To address this, we designed a straw enzymatic hydrolysis silo discharge anti-blocking device. Utility Model Content

[0005] This utility model discloses a straw enzymatic hydrolysis square bin discharge anti-clogging device. To achieve the above objective, this utility model adopts the following technical solution: A straw enzymatic hydrolysis square bin discharge anti-blocking device includes a support frame, a bin body is fixedly mounted on the upper surface of the support frame, and an anti-blocking mechanism is provided at the bottom of the bin body; The anti-blocking mechanism includes a feeding hopper, which is located inside the silo body. A rectangular rubber ring is fixedly connected between the top of the feeding hopper and the inner wall of the silo body. The anti-blocking mechanism also includes two rotating shafts rotatably mounted on the silo body and two crushing rollers rotatably connected to the inner wall of the silo body. The two crushing rollers are symmetrically distributed below the feeding hopper, and the two rotating shafts are symmetrically distributed above the feeding hopper.

[0006] In a preferred embodiment, a plurality of movable rods are fixedly connected to the surface of the rotating shaft, and the plurality of movable rods are evenly distributed on the surface of the rotating shaft. One end of the rotating shaft extends to the outside of the hopper body and is fixedly connected to a first transmission pulley. One end of the crushing roller extends to the outside of the hopper body and is fixedly connected to a second transmission pulley.

[0007] In a preferred embodiment, a third drive pulley is rotatably connected to the front of the hopper body, and a drive belt is installed between the first drive pulley, the second drive pulley and the third drive pulley, and the first drive pulley, the second drive pulley and the third drive pulley rotate synchronously through the drive belt.

[0008] In a preferred embodiment, a rotary cam is fixedly connected to the surface of the third transmission pulley, and extension blocks are fixedly connected to the front and rear surfaces of the discharge hopper. The end of the extension block away from the discharge hopper extends to the outside of the hopper body and is fixedly connected to a movable frame. The position of the movable frame corresponds to the rotary cam, and the rotary cam overlaps with the lower surface of the movable frame.

[0009] In a preferred embodiment, rectangular limiting holes are provided on both the front and rear surfaces of the hopper body. A limiting rod is fixedly connected to the inner wall of the rectangular limiting hole. The extension block is slidably connected to the surface of the limiting rod. A return spring is sleeved on the surface of the limiting rod. The bottom end of the return spring is fixedly connected to the upper surface of the extension block, and the top end of the return spring is fixedly connected to the inner top wall of the rectangular limiting hole.

[0011] In a preferred embodiment, the feeding hopper is located directly above the two crushing rollers, and two guide blocks are symmetrically fixed to the bottom of the inner wall of the hopper body, with the two guide blocks symmetrically distributed on both sides of the crushing rollers.

[0012] As can be seen from the above, the straw enzymatic hydrolysis silo discharge anti-blocking device provided by this utility model has the following technical effects.

[0013] 1. The device achieves anti-clogging through the synergistic effect of multiple structures. The two upper rotating shafts have evenly distributed movable rods on their surfaces. During rotation, these rods stir and loosen the straw above the feeding hopper, preventing it from accumulating and clogging. The two lower crushing rollers rotate in opposite directions, crushing the falling straw, breaking up clumps, and preventing large pieces of straw from blocking the discharge channel. The feeding hopper vibrates up and down under the action of a rotating cam and a return spring, further promoting the straw's descent and reducing stagnation and blockage within the hopper, achieving efficient anti-clogging and ensuring smooth discharge. Two guide blocks at the bottom of the hopper are symmetrically distributed on both sides of the crushing rollers, guiding the crushed straw towards the discharge port, preventing accumulation in the bottom corners, and ensuring smooth overall discharge.

[0014] 2. The device uses a transmission belt to connect the first, second, and third transmission pulleys, enabling synchronous rotation of the rotating shaft, crushing roller, and rotating cam. Multiple components can work together with just one drive motor, reducing the use of power sources, lowering energy consumption, and ensuring coordinated movement of each structure, thereby improving the overall working efficiency of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5A straw enzymatic hydrolysis hopper discharge anti-blocking device includes a support frame 1, on the upper surface of the support frame 1 a hopper body 2 is fixedly installed, the hopper body 2 serves as the main space for temporary storage and processing of straw, and an anti-blocking mechanism 3 is installed at its bottom, the anti-blocking mechanism 3 includes a discharge hopper 301, a rectangular rubber ring 302, a guide inclined block 303, a rotating shaft 304, a crushing roller 305, a movable rod 307 and other components.

[0023] The feeding hopper 301 is located inside the silo body 2, and rectangular rubber rings 302 are fixedly connected to the top and surrounding perimeter of the hopper 301 and the inner wall of the silo body 2. The rectangular rubber rings 302 not only ensure the sealing between the feeding hopper 301 and the silo body 2, preventing straw from leaking out from the gaps, but also accommodate the up-and-down vibration of the feeding hopper 301 without affecting its dynamic anti-clogging function, thus enhancing the stability of the device operation.

[0024] Two rotating shafts 304 are rotatably mounted inside the hopper body 2, symmetrically distributed above the discharge hopper 301. Several movable rods 307 are fixedly connected to the surface of each rotating shaft 304, and these movable rods 307 are evenly distributed across the surface of the rotating shaft 304. When the rotating shaft 304 rotates, the movable rods 307 rotate synchronously with it, which can stir and loosen the straw above the discharge hopper 301, preventing the straw from clogging the discharge channel due to accumulation and compaction, thus reducing the risk of blockage from the source.

[0025] Two crushing rollers 305 are rotatably connected to the inner wall of the hopper body 2, symmetrically distributed below the discharge hopper 301, with the discharge hopper 301 located directly above the two crushing rollers 305. This ensures that the straw falling from the discharge hopper 301 can directly enter between the two crushing rollers 305. Two guide blocks 303 are symmetrically fixed to the bottom of the inner wall of the hopper body 2. These guide blocks 303 are symmetrically distributed on both sides of the crushing rollers 305, guiding the crushed straw to gather at the discharge port, preventing accumulation in the bottom corners, and further ensuring smooth discharge.

[0026] One end of the rotating shaft 304 extends to the outside of the hopper body 2 and is fixedly connected to a first transmission pulley 308; one end of the crushing roller 305 extends to the outside of the hopper body 2 and is fixedly connected to a second transmission pulley 309; a third transmission pulley 310 is rotatably connected to the front of the hopper body 2. A transmission belt 311 is installed between the first transmission pulley 308, the second transmission pulley 309, and the third transmission pulley 310, enabling the three to rotate synchronously. This design ensures coordinated movement of the rotating shaft 304 and the crushing roller 305, guaranteeing the continuity of the mixing and crushing processes and improving anti-clogging efficiency.

[0027] A rotary cam 312 is fixedly connected to the surface of the third transmission pulley 310. Extension blocks 320 are fixedly connected to both the front and rear surfaces of the feeding hopper 301. One end of the extension block 320, away from the feeding hopper 301, extends to the outside of the hopper body 2 and is fixedly connected to a movable frame 313. The movable frame 313 is positioned corresponding to the rotary cam 312, and the lower surface of the rotary cam 312 overlaps with the lower surface of the movable frame 313. When the third transmission pulley 310 drives the rotary cam 312 to rotate, the protruding part of the rotary cam 312 periodically pushes up the movable frame 313, thereby causing the feeding hopper 301 to rise, achieving the vibration function of the feeding hopper 301, promoting rapid straw fall, and reducing stagnation and blockage.

[0028] The support frame 1 is equipped with a plate-shaped conveyor belt located directly below the hopper 301. Several toothed strips are fixedly installed on the surface of the plate-shaped conveyor belt. The crushed straw is guided by the guide block 303 to gather at the discharge port at the bottom of the hopper body 2 and then falls onto the plate-shaped conveyor belt for conveying.

[0029] Rectangular limiting holes 314 are provided on both the front and rear surfaces of the hopper body 2. A limiting rod 315 is fixedly connected to the inner wall of the rectangular limiting hole 314. The extension block 320 is slidably connected to the surface of the limiting rod 315. The limiting rod 315 guides and limits the movement of the extension block 320, preventing the discharge hopper 301 from shifting or shaking during vibration, and ensuring stable operation of the device. A return spring 316 is sleeved on the surface of the limiting rod 315. The bottom end of the return spring 316 is fixedly connected to the upper surface of the extension block 320, and the top end is fixedly connected to the inner top wall of the rectangular limiting hole 314. When the protruding part of the rotating cam 312 leaves the movable frame 313, the elastic force of the return spring 316 will pull the extension block 320 down, causing the discharge hopper 301 to return to its original position, making the vibration of the discharge hopper 301 more stable, reducing hard collisions between components, and extending the service life of the device.

[0030] Two second transmission pulleys 309 are respectively fixedly connected to a drive gear 317 and a driven gear 318, with the drive gear 317 meshing with the driven gear 318. A drive motor 319 is fixedly connected to the back of the hopper body 2, and the rotating shaft of the drive motor 319 is fixedly connected to the other end of the crushing roller 305 corresponding to the drive gear 317. When the drive motor 319 is working, it drives the two crushing rollers 305 to rotate in opposite directions through the meshing of the drive gear 317 and the driven gear 318, enhancing the crushing effect on the straw, effectively breaking up clumps, and preventing large pieces of straw from clogging the discharge port. At the same time, the drive motor 319 drives the first transmission pulley 308 and the third transmission pulley 310 to rotate synchronously through the second transmission pulley 309 and the transmission belt 311, reducing the power source usage and lowering energy consumption.

[0031] Working principle: When in use, start the drive motor 319, which drives the crushing roller 305 connected to the drive gear 317 to rotate. Through the meshing of the drive gear 317 and the driven gear 318, the two crushing rollers 305 rotate in opposite directions. At the same time, the second transmission pulley 309 at one end of the crushing roller 305 drives the first transmission pulley 308 and the third transmission pulley 310 to rotate synchronously through the transmission belt 311, thereby starting the rotating shaft 304 and the rotating cam 312 to work. The movable rod 307 on the surface of the rotating shaft 304 rotates with the shaft to stir and loosen the straw above the feeding hopper 301, preventing it from piling up. The third transmission pulley 310 drives the rotating cam 312 to rotate. The rotating cam 312 periodically lifts the movable frame 313, and with the elastic force of the return spring 316, the feeding hopper 301 vibrates up and down, causing the straw to fall quickly between the crushing rollers 305 below. The two counter-rotating crushing rollers 305 crush the falling straw, breaking up the clumps. The crushed straw is guided by the guide inclined block 303 to gather at the discharge port at the bottom of the hopper body 2, and finally falls onto the plate conveyor belt to be transported to the outside.

[0032] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
