By rotating the adjusting wheel, the wires can be intertwined, thereby adjusting the tightness of the constraint on the wire and ensuring baling stability.

Description

Technical Field

[0001] This utility model relates to the technical field of biomass fuel processing equipment, specifically to a straw compaction and bundling device for biomass fuel processing. Background Technology

[0002] Straw is a general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after the grains are harvested. More than half of the products of crop photosynthesis are found in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. After being burned as fuel, the ash can also be used as fertilizer. It is a multi-purpose renewable biological resource.

[0003] Compaction and baling equipment is a type of machinery that can compress, compact, and bale loose biomass raw materials such as straw into a fixed shape. Through this process, straw, which is originally bulky and inconvenient to transport and store, is transformed into high-density bale fuel, which provides convenience for subsequent biomass power generation, heating, and briquette processing.

[0004] Existing biomass fuel processing equipment typically requires manual labor to bind the straw after compaction by pulling on baling ropes multiple times around the compacted straw. This process is cumbersome and extremely labor-intensive. Furthermore, some straw compaction and baling equipment, when using ropes of varying thicknesses, not only requires manual pulling around the straw but also lacks an adjustable wiring device, leading to situations where the ropes easily come loose or fail to pass through the wiring device during baling. Therefore, we propose a straw compaction and baling device for biomass fuel processing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a straw compaction and bundling device for biomass fuel processing, which solves the problems of requiring manual wrapping of the straw frequently during bundling and the inability to fix and guide ropes of different thicknesses.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A straw compaction and baling device for biomass fuel processing includes a compaction device, a hydraulic plate for pushing out is provided at the left end of the compaction device, the output end of the hydraulic plate for pushing out extends into the interior of the compaction device, a baling component is provided in the middle of the compaction device, and an operation button is provided at the rear of the top of the compaction device.

[0008] Preferably, the compaction device includes a main body, an operating groove at the top of the main body, an arc-shaped bottom end of the operating groove, and several pressure plate moving grooves on the front and rear sides of the inner wall of the operating groove. A hydraulic rod is fixedly connected to the end of the inner side of the pressure plate moving groove away from the operating groove, and a compaction arc plate is fixedly connected to the output end of the hydraulic rod. Two corresponding compaction arc plates can be combined to form a cylindrical shape.

[0009] Preferably, the binding assembly includes an enclosing ring embedded and rotatably connected to the center of the device body. The enclosing ring is a three-quarter circle. Rotating guide grooves are provided on both the left and right sides of the enclosing ring inside the device body. Several movable sliding pillars are fixedly connected to the left and right ends of the enclosing ring. The several movable sliding pillars on the same side are slidably connected to the inner side of the adjacent rotating guide groove. A wire passing groove is provided on the outer surface of the enclosing ring, and a wire binding assembly is rotatably connected to one end of the wire passing groove.

[0010] Preferably, the diameter of the surrounding ring is larger than that of the compacted arc plate, and the inner curvature of the surrounding ring is the same as that of the bottom of the inner side of the operating groove and they are on the same plane.

[0011] Preferably, the wire harness assembly includes a connecting block fixedly connected to the left end of the inner side of the wire channel. Two constraint lines are fixedly connected to the right end of the connecting block. The two constraint lines form a V-shape with the connecting block as the contact point. An adjusting wheel is fixedly connected to the right end of the two constraint lines. The left and right ends of the adjusting wheel are rotatably connected to the inside of the surrounding ring. The outer surface of the adjusting wheel extends to the outside of the surrounding ring.

[0012] Preferably, the right end of the adjusting wheel has a plurality of locking grooves arranged in an array around the center of the adjusting wheel, and a locking pin is provided on the right side of the adjusting wheel. The right end of the locking pin is fixedly connected to an unlocking post extending to the outside of the surrounding ring at one end away from the locking pin. The unlocking post is slidably connected inside the surrounding ring, and the right end of the unlocking post is fixedly connected to a support spring at the other end fixedly connected inside the surrounding ring. One half of the locking pin near the adjusting wheel is inclined and can enter the locking groove.

[0013] This utility model provides a straw compaction and baling device for biomass fuel processing. Compared with the prior art, it has the following advantages: the baling component's surrounding ring, in conjunction with the movable sliding column, slides along the rotating guide groove, allowing it to rotate around the compacted straw. Combined with the wire passage groove and the wire binding component, the wire can be wrapped around the compacted straw simply by rotating the baling component, eliminating the need for manual pulling and winding of the wire, greatly simplifying the operation process, reducing labor consumption, and improving baling efficiency. Furthermore, the adjusting wheel in the wire binding component, in conjunction with the V-shaped constraint line, allows the wires to intertwine by rotating the adjusting wheel, thereby adjusting the tightness of the constraint on the wire. At the same time, the locking pin and locking groove automatically fix the adjusted state during rotation, preventing the wire from falling off during baling or failing to pass through the wire device due to mismatched thickness. This enhances the equipment's adaptability to different specifications of rope and ensures baling stability. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1 to 5This utility model provides a technical solution:

[0022] A straw compaction and baling device for biomass fuel processing includes a compaction device 2, a hydraulic ejector plate 1 at the left end of the compaction device 2, the output end of the hydraulic ejector plate 1 extending into the interior of the compaction device 2, a baling component 4 in the middle of the compaction device 2, and an operation button 3 at the rear of the top of the compaction device 2.

[0023] The equipment is started by operating button 3. The straw enters the compaction device 2 from above. After being compacted, the hydraulic plate 1 pushes it out of the compaction device 2. At the same time, the binding component 4 drives the rope to wrap around the compacted straw. All components work together to complete the straw compaction and binding process.

[0024] Furthermore, the compaction device 2 includes a device body 21. The top of the device body 21 is provided with an operating groove 25. The bottom of the operating groove 25 is arc-shaped. Several pressure plate moving grooves 22 are provided on the front and rear sides of the inner wall of the operating groove 25. A hydraulic rod 23 is fixedly connected to the end of the inner side of the pressure plate moving groove 22 away from the operating groove 25. A compaction arc plate 24 is fixedly connected to the output end of the hydraulic rod 23. Two corresponding compaction arc plates 24 can be combined to form a cylindrical shape.

[0025] When the compaction device 2 is working, the straw is placed into the operating slot 25 at the top of the main body 21 of the device. The hydraulic rod 23 inside the pressing plate moving slot 22 is activated, pushing the compaction arc plate 24 into the operating slot 25. The two corresponding compaction arc plates 24 are combined into a cylindrical shape, squeezing the straw from the front and rear sides to achieve compaction of the straw. After compaction, the compaction arc plate 24 can retract, and the newly entered straw is combined with the squeezed straw again for compaction to ensure the compaction density.

[0026] The hydraulic plate 1 and hydraulic rod 23 are existing technologies and will not be explained here.

[0027] Furthermore, the binding assembly 4 includes an enclosing ring 43 embedded and rotatably connected to the center of the device body 21. The enclosing ring 43 is three-quarters of a circle. Rotating guide grooves 45 are provided on both the left and right sides of the enclosing ring 43 inside the device body 21. Several movable sliding pillars 44 are fixedly connected to the left and right ends of the enclosing ring 43. Several movable sliding pillars 44 on the same side are slidably connected to the inner side of the adjacent rotating guide grooves 45. A wire passage groove 42 that runs through the inner and outer sides is provided on the outer surface of the enclosing ring 43. A wire binding assembly 41 is rotatably connected to one end of the wire passage groove 42.

[0028] When the binding component 4 is working, the surrounding ring 43 embedded in the center of the device body 21 begins to rotate. The movable sliding pins 44 at its left and right ends slide along the rotating guide grooves 45 inside the device body 21, providing guidance and support for the rotation of the surrounding ring 43. Since the surrounding ring 43 is a three-quarter circle, it can ensure that it does not detach from the device body 21 and will not block the straw from entering the operating groove 25. When rotating, it can wrap around the outside of the compacted straw. The rope is fixed on the binding component 41 and enters through the wire groove 42 as the surrounding ring 43 rotates. It remains stable under the action of the binding component 41 and achieves the wrapping and binding of the straw as the surrounding ring 43 rotates.

[0029] Furthermore, the diameter of the surrounding ring 43 is larger than that of the compacted arc plate 24, and the inner curvature of the surrounding ring 43 is the same as that of the inner bottom end of the operating groove 25 and they are on the same plane.

[0030] When the surrounding ring 43 is working, because its diameter is larger than that of the compaction arc plate 24, the surrounding ring 43 can smoothly rotate around the straw after it is compacted by the compaction arc plate 24, so that the rope can tie it. The inner curvature of the surrounding ring 43 is the same as the inner bottom end of the operating groove 25 and is on the same plane, so that when it rotates around the straw to tie it, it can better fit the outer contour of the straw and ensure that the tying position is accurate and stable.

[0031] Furthermore, the wire harness assembly 41 includes a connecting block 418 fixedly connected to the left end of the inner side of the wire channel 42. Two constraint lines 417 are fixedly connected to the right end of the connecting block 418. The two constraint lines 417 form a V-shape with the connecting block 418 as the contact point. An adjusting wheel 415 is fixedly connected to the right end of the two constraint lines 417. The left and right ends of the adjusting wheel 415 are rotatably connected to the inside of the surrounding ring 43. The outer surface of the adjusting wheel 415 extends to the outside of the surrounding ring 43. Several openings are provided around the right end of the adjusting wheel 415. The locking groove 414 of the 415-circle array is provided with a locking pin 413 on the right side of the adjusting wheel 415. The right end of the locking pin 413 is fixedly connected to an unlocking post 412 that extends to the outside of the surrounding ring 43 at the end away from the locking pin 413. The unlocking post 412 is slidably connected to the inside of the surrounding ring 43. The right end of the unlocking post 412 is fixedly connected to a support spring 411 that is fixedly connected to the inside of the surrounding ring 43 at the other end. One half of the end of the locking pin 413 near the adjusting wheel 415 is inclined and can enter the locking groove 414.

[0032] The rope is inserted between two constraint lines 417. Then, the adjusting wheel 415 is rotated. The rotation of the adjusting wheel 415 causes the two constraint lines 417 to intertwine, thereby fixing one end of the rope. The tightness of the constraint on the rope is adjusted. As the adjusting wheel 415 rotates, the locking pin 413, under the action of the support spring 411, slides against the locking groove 414 on the right end of the adjusting wheel 415. After adjusting to the appropriate position, the locking pin 413 is engaged in the corresponding locking groove 414 to fix the adjusting wheel 415. To unlock, the unlocking pin 412 is pulled to disengage the locking pin 413 from the locking groove 414. When the unlocking pin 412 is pulled to unlock, the adjusting wheel 415 automatically rotates and resets under the reaction force of the two intertwined constraint lines 417.

[0033] The constraint line 417 is made of nylon fiber, which is both elastic and tough, and can fix the wire harness.

[0034] Working principle:

[0035] In use, first place the straw into the operating slot 25 at the top of the main body 21 of the device, press the operation button 3 to start the equipment, the hydraulic rod 23 pushes the compaction arc plate 24 to move into the operating slot 25, the corresponding front and rear compaction arc plates 24 are combined into a cylindrical shape, and the straw is squeezed from both sides to complete the compaction. After compaction, the V-shaped constraint line 417 of the wire assembly 41 limits the rope. The angle of the constraint line 417 can be adjusted by rotating the adjusting wheel 415 to adapt to the thickness of the rope. The locking pin 413 is locked into the locking slot 414. As the surrounding ring 43 rotates, the rope wraps around the straw to complete the binding. The surrounding ring 43 rotates along the rotating guide groove 45 through the moving slide column 44. The rope enters through the wire groove 42 of the surrounding ring 43. Finally, the hydraulic plate 1 pushes out the bundled straw from the compaction device 2, thus completing the processing.
