Description

Technical Field

[0001] The present application relates to the technical field of straw briquetting, and in particular to a straw briquetting production device. Background Art

[0002] For a long time, people have used plant straw, peanut shells, corn cobs, rice husks, wheat bran, leaves, weeds, wood chips, and sawdust in their loose form as fuel. These fuels are inconvenient to use and have low thermal efficiency. With socioeconomic changes and the influx of commercial energy into rural households, large amounts of crop straw have become waste or are burned outdoors, severely impacting the environment.

[0003] At present, most of the existing straw briquetting devices crush the hollow straw into powder and then squeeze it into blocks. However, in the actual production process, this type of equipment still has many technical bottlenecks and safety hazards. Specifically, due to the characteristics of straw itself such as different lengths and strong toughness, it is very easy to get stuck at the feed port during the feeding process, resulting in poor feeding. Traditional solutions mostly rely on the operator to directly move the stuck straw by hand to resume feeding, but at this time the feed port is usually connected to the conveying mechanism, and the equipment is in a high-speed operation state. The operator needs to be in close contact with the moving parts, which can easily cause personal injury accidents and pose a significant safety risk. In addition, the feeding of existing equipment is difficult to operate. The material control method is relatively extensive and lacks an accurate quantitative adjustment mechanism, making it difficult to achieve stable control of material throughput, resulting in large fluctuations in production efficiency. Finally, in the crushing link, traditional devices generally adopt a single-direction rotating crushing structure, which can only perform preliminary crushing of the straw through a single impact. Its crushing efficiency is low and the product fineness is insufficient. At the same time, the centrifugal force generated during the crushing process can easily cause the overall vibration of the equipment to intensify, which not only increases the basic load, but also leads to increased energy consumption. What is more serious is that the crushed material is easy to adhere to the surface of the crushing wheel and the supporting bottom plate, resulting in frequent blockage problems and frequent shutdowns for cleaning, which seriously affects production continuity and increases maintenance costs. Summary of the Invention

[0004] The present application proposes a straw briquetting production device, which has the advantage of automatically pushing the material stuck in the feed port, so as to solve the problem in the prior art that the processing personnel need to actively move the straw.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a straw briquetting production device, comprising a first supporting base plate, a mounting block fixedly connected to one side of the top of the first supporting base plate, and a transmission assembly disposed inside the mounting block; The interior of the mounting block is movably sleeved with a third rotating shaft, and the outer side of the third rotating shaft is provided with a conversion assembly; A crushing bin is fixedly connected to one side of the mounting block, a second supporting base plate is provided at the bottom of the crushing bin, and a crushing assembly is provided inside the crushing bin; A conveying screw is provided at the bottom of the crushing bin, a conveying bin is fixedly connected to one side of the crushing bin, a feeding bin is fixedly connected to one side of the feeding bin, a feeding hopper is fixedly connected to the top of the feeding bin, and a quantitative feeding assembly is provided inside the feeding bin; A support block is fixedly connected to one side of the feed bin, and a second support base plate is fixedly connected to the bottom of the support block.

[0008] Preferably, the crushing assembly includes an extrusion block, which is fixedly connected to one end of the connecting shaft sleeve, and the extrusion block is movably sleeved on the outer side of the third rotating shaft, and multiple groups of extrusion grooves are opened on the outer side of the extrusion block.

[0010] Preferably, the quantitative unloading assembly includes a cylinder, which is fixedly connected to the inside of the support block, the output end of the cylinder is fixedly connected to a connecting column, one end of the connecting column is fixedly connected to a connecting frame, the inside of the connecting frame is fixedly connected to multiple groups of limit plates, the inside of the feed bin is fixedly connected to multiple groups of first quantitative blocks, the inside of the feed bin is fixedly connected to multiple groups of second quantitative blocks, and the outer side of the third rotating shaft is fixedly connected to a conveying screw.

[0011] Preferably, the upper surface of the limit plate abuts against the first quantitative block, and the lower surface of the limit plate abuts against the second quantitative block. A fixed-length feed trough will be formed between multiple groups of the first quantitative blocks. The width of the second quantitative block is equal to the width of the feed trough. Multiple groups of the second quantitative blocks are in the same vertical position as the feed trough. When feeding, the material entering the feed bin can be quantitatively discharged through the limit plate by moving the limit plate. At the same time, the material blocked in the feed port can be pushed by the first quantitative block to improve safety.

[0012] Preferably, the top of the first quantitative block is triangular, so as to avoid accumulation of materials on the top of the first quantitative block, thereby causing waste of materials.

In the unloading process, the reciprocating limit plate will push the straw stuck at the feed port, so that the feeding can be completed without manual unloading. In the unloading process, the continuity of the unloading process is ensured, and the safety hazard of operators contacting high-speed running parts is eliminated, which significantly improves production safety and reliability. This innovative design realizes the automation, quantification and safety of material handling through the precise coordination of the mechanical structure, fully demonstrating the technical advantages of the mechanical linkage system.

[0016] 2. The present invention cleverly arranges a conversion component to cause the extrusion block and its internal eccentric wheel to rotate in opposite directions with the crushing component, achieving a coaxial reversal effect. During actual operation, the centrifugal inertia force generated by the eccentric wheel and the reverse motion of the crushing component cooperate with each other to form a dynamic superposition effect, thereby enhancing the impact energy transfer to the material. At the same time, the reverse rotation of the extrusion block and the crushing component constructs an opposing shear force field, causing the material to undergo bidirectional extrusion and tearing, effectively improving the crushing efficiency and product fineness. In addition, the coaxial reversal design balances the centrifugal forces of the two sets of rotating bodies, significantly reducing the overall vibration of the equipment during operation, thereby reducing the foundation load and energy consumption.

[0017] 3.

In addition, a scraper is fixedly provided in the middle of the outer surface of the crushing knife. During the crushing operation, the scraper will simultaneously scrape off the residual materials attached to the surface of the crushing wheel and the supporting bottom plate, successfully solving the problem of blockage that may be caused by material adhesion. The integrated design of the crushing knife and the scraper combines efficient crushing function and excellent self-cleaning ability, greatly reducing the frequency of equipment shutdown and maintenance.

A second supporting base plate 35 is provided at the bottom of the crushing bin 16. A crushing assembly is provided inside the crushing bin 16. A conveying screw 33 is provided at the bottom of the crushing bin 16, a conveying bin 17 is fixedly connected to one side of the crushing bin 16, a feeding bin 18 is fixedly connected to one side of the feeding bin 17, a feeding hopper 19 is fixedly connected to the top of the feeding bin 18, and a quantitative feeding assembly is provided inside the feeding bin 18; A support block 34 is fixedly connected to one side of the feed bin 18, and a second support base plate 35 is fixedly connected to the bottom of the support block 34; The power is converted into multi-directional motion through the cooperation of the third rotating shaft 9 and the conversion component, driving the crushing component to crush the straw. The crushing component arranged in the crushing bin 16 continuously squeezes and crushes the straw through the mechanical structure. The discharge port 36 is connected with the conveying screw 33 to realize material transfer. The linkage design of the conveying bin 17 and the feed bin 18, combined with the limit plate 30 and the quantitative block in the quantitative unloading component, can accurately control the flow of materials into the reaction bin 1, thereby avoiding blockage of the feed port. The entire solution realizes the full process automation of straw from feeding to briquetting through the coordination of mechanical transmission and structure, without the need for manual intervention in material selection, effectively eliminating safety hazards.

[0023] Among them, the transmission assembly includes a driving motor 3, which is arranged on one side of the mounting block 2, and the driving motor 3 is fixedly connected to the first supporting base plate 1. The output end of the driving motor 3 is fixedly connected to the first rotating shaft 4, and the first rotating shaft 4 is rotatably connected to the mounting block 2. The outer side of the first rotating shaft 4 is fixedly connected to the first pulley 5, and the top side of the first supporting base plate 1 is fixedly connected to the support plate 6. The second rotating shaft 7 is movably sleeved on one side of the support plate 6, and the outer side of the second rotating shaft 7 is sleeved with a double-groove pulley 8. The outer side of the third rotating shaft 9 is movably sleeved with a second pulley 10. A transmission belt 11 is sleeved between the first pulley 5 and the double-groove pulley 8 and between the double-groove pulley 8 and the second pulley 10. The power of the driving motor 3 is transmitted to the third rotating shaft 9 through the transmission belt 11, so that the third rotating shaft 9 can be driven by the driving motor 3 to realize rotation; By driving the motor 3 as a power source, the power is transmitted to the first rotating shaft 4, the first pulley 5, the double-groove pulley 8 and the second pulley 10 in sequence, and finally the third rotating shaft 9 is driven to rotate. During operation, the setting of the support plate 6 enhances the supporting strength of the second rotating shaft 7 to prevent the transmission belt 11 from being offset due to vibration. Then the double-groove pulley 8 cooperates with the transmission belt 11 of the first pulley 5 and the second pulley 10 to realize multi-stage power transmission, so that the third rotating shaft 9 can run at a speed adapted to the requirements of subsequent components. The entire transmission structure replaces manual operation with mechanical linkage, automates the material transportation and processing processes, and reduces the risk of personnel contacting high-speed running parts.

[0024] Among them, the conversion component includes a first crown gear 12, which is fixedly sleeved on the outer side of the third rotating shaft 9. Fixed blocks 13 are provided on both sides of the first crown gear 12. The two sets of fixed blocks 13 are fixedly connected to the mounting block 2. One side of the fixed block 13 is movably sleeved with an engaging column 14. One side of the engaging column 14 is meshedly connected with a second crown gear 15. The second crown gear 15 is movably sleeved on the outer side of the third rotating shaft 9. The fixed block 13 is meshed with the first crown gear 12 and the second crown gear 15 respectively. One side of the second crown gear 15 is fixedly connected to a connecting sleeve 20, which is movably sleeved on the outer side of the third rotating shaft 9. The precise meshing linkage design of the double crown gears and the fixed block 13 successfully constructs an efficient and stable multi-directional power transmission system. The first crown gear 12 serves as the core driving gear, directly receiving the power input from the third rotating shaft 9. The symmetrically arranged fixed blocks 13 on both sides not only form a stable and rigid support structure, but also cleverly form a planetary gear transmission system through the meshing column 14 and the second crown gear 15. This innovative layout enables the second crown gear 15 and the third rotating shaft 9 to achieve precise coaxial counter-rotating motion, and efficiently converts rotational power into axial motion output through the connecting sleeve 20. Particularly notable is the three-point positioning structure formed by the fixed block 13 and the double crown gears, which not only ensures the stability and reliability of the transmission process but also achieves precise and controllable conversion of power direction. The unique socket connection between the connecting sleeve 20 and the third rotating shaft 9 not only gives the second crown gear 15 freedom of rotation but also perfectly realizes the efficient transmission of power to the subsequent actuators, fully demonstrating the technical advantages of this design in power distribution, structural stability and motion flexibility.

[0025] The crushing assembly includes an extrusion block 21, which is fixedly connected to one end of the connecting sleeve 20, and is movably sleeved on the outer side of the third rotating shaft 9. The outer side of the extrusion block 21 is provided with multiple groups of extrusion grooves 22; The power of the transmission system is transmitted to the extrusion block 21 through the connecting shaft sleeve 20, so that the extrusion block 21 can rotate synchronously with the third rotating shaft 9. The movable sleeve structural design enables the extrusion block 21 to form a dynamic extrusion space during the rotation process, and multiple groups of extrusion grooves 22 form a continuously changing crushing area during rotation. When the straw enters the crushing bin 16, the rotational movement of the extrusion block 21 drives the extrusion grooves 22 to crush the material at multiple angles, and the trough structure produces a dual effect of shear force and extrusion force on the straw. This structure is particularly designed for the physical properties of hollow straw, and uses the cutting line formed on the edge of the extrusion groove 22 to segmentally crush the long strips of straw to avoid the whole straw from being stuck in the crushing bin 16. The array distribution of the extrusion grooves 22 forms alternating crushing areas, which generates continuous waves of crushing force during the rotation process, effectively solving the problem of material accumulation that is easily caused by traditional planar crushing structures.

[0026] The crushing assembly further includes an eccentric wheel 23, which is fixedly sleeved on the outer side of the third rotating shaft 9. A cutting groove 37 is formed inside the eccentric wheel 23. A crushing wheel 24 is movably sleeved on the outer side of the third rotating shaft 9. The crushing wheel 24 is arranged inside the cutting groove 37. Multiple groups of crushing knives 25 are fixedly connected to the outer side of the crushing wheel 24. One end of the crushing knife 25 is fixedly connected to a scraper 26, and the scraper 26 is fixedly connected to the middle part of the outer surface of the crushing knife 25. During the operation of the equipment, the eccentric wheel 23 is firmly fixed and sleeved on the outer side of the third rotating shaft 9. When the third rotating shaft 9 starts to rotate, the eccentric motion generated by it drives the crushing wheel 24 to perform asymmetric crushing motion inside the second supporting base plate 35. This unique motion form significantly enhances the shearing and squeezing effect on the material. At the same time, the crushing wheel 24 is mounted on the third rotating shaft 9 in a movable sleeve manner, which enables it to produce periodic displacement changes under the precise drive of the eccentric wheel 23, effectively avoiding the problem of local material accumulation easily caused by the traditional fixed crushing path. At the same time, multiple groups of crushing knives 25 are reasonably distributed along the outer side of the crushing wheel 24, cutting the straw from multiple angles, greatly improving the crushing efficiency. In addition, a scraper 26 is fixedly provided in the middle of the outer surface of the crushing knife 25. During the crushing operation, the scraper 26 will simultaneously scrape off the residual material attached to the crushing wheel 24 and the surface of the supporting bottom plate, successfully solving the problem of blockage that may be caused by material adhesion. The integrated design of the crushing knife 25 and the scraper 26 combines efficient crushing function and excellent self-cleaning ability, greatly reducing the frequency of equipment shutdown and maintenance.

[0027] Among them, the quantitative unloading assembly includes a cylinder 27, which is fixedly connected to the inside of the support block 34, the output end of the cylinder 27 is fixedly connected to a connecting column 28, one end of the connecting column 28 is fixedly connected to a connecting frame 29, the interior of the connecting frame 29 is fixedly connected to multiple groups of limit plates 30, the interior of the feed bin 18 is fixedly connected to multiple groups of first quantitative blocks 31, the interior of the feed bin 18 is fixedly connected to multiple groups of second quantitative blocks 32, and the outer side of the third rotating shaft 9 is fixedly connected to a conveying screw 33; By using the cylinder 27 as the power source, the connecting column 28 is precisely driven to coordinately drive the connecting frame 29 and the limit plate 30 to perform reciprocating motion, and through the alternating abutment mechanism between the limit plate 30 and the first quantitative block 31 and the second quantitative block 32, an efficient and stable dynamic unloading channel is constructed. In this design, the fixed-length unloading trough formed by multiple groups of first quantitative blocks 31 and the equal-width design of the second quantitative block 32 are cleverly coordinated to ensure the precise control of the material passing amount during the movement of the limit plate 30, realizing the mechanized quantitative unloading operation. At the same time, the conveying screw 33 arranged on the outside of the third rotating shaft 9 continues to operate to ensure the continuity and flow of material transportation. The smooth operation of the feeding port completely avoids the risk of clogging in the feeding port that is easily caused by the traditional manual feeding method. In particular, the triangular structure design adopted on the top of the first quantitative block 31 can effectively guide the material to slide smoothly into the feeding chute, avoiding the accumulation of material on the top of the quantitative block and causing waste; and the entire component system completely replaces manual intervention through mechanical linkage, which not only ensures the continuity of the feeding process, but also eliminates the safety hazard of operators contacting high-speed running parts, significantly improving production safety and reliability. This innovative design realizes the automation, quantification and safety of material handling through the precise coordination of the mechanical structure, fully demonstrating the technical advantages of the mechanical linkage system.

[0028] Among them, the upper surface of the limiting plate 30 abuts against the first quantitative block 31, and the lower surface of the limiting plate 30 abuts against the second quantitative block 32. A fixed-length feeding trough is formed between multiple groups of first quantitative blocks 31. The width of the second quantitative block 32 is equal to the width of the feeding trough. Multiple groups of second quantitative blocks 32 are all in the same vertical position as the feeding trough. When feeding, the material entering the feed bin 18 can be quantitatively dialed and discharged through the limiting plate 30 by moving the limiting plate 30. At the same time, the material blocked in the feed port can be pushed by the first quantitative block 31 to improve safety. Through the precise coordination of the limiting plate 30 with the first quantitative block 31 and the second quantitative block 32, a set of efficient and stable dynamic quantitative unloading system is successfully constructed. Among them, the precise contact between the limiting plate 30 and the first quantitative block 31 strictly limits the longitudinal size of the unloading trough, forming a standardized fixed-length material channel; and the equal-width design of the second quantitative block 32 and the unloading trough ensures the size adaptability of the material when it passes through, and the vertically aligned layout further ensures the continuity and stability of the material flow. During operation, the reciprocating motion of the limiting plate 30 not only realizes the precise quantitative unloading of the material, but also realizes the precise quantitative unloading of the material through the coordination with the first quantitative block 31. 1, which produces a mechanical pushing effect on the material accumulation that may appear at the feed port, effectively eliminating the risk of blockage at the source. What is particularly outstanding is that the active pushing function of the first quantitative block 31 completely replaces the traditional manual intervention operation, which not only improves production efficiency, but also fundamentally eliminates the safety hazards of workers coming into contact with high-speed running equipment. This innovative structure cleverly integrates the dual functions of automatic processing of blocked materials and quantitative unloading through a mechanical linkage mechanism. While significantly improving production efficiency, it greatly enhances the inherent safety level of the equipment, providing a solid guarantee for the safe and efficient operation of the production process.

[0029] The top of the first quantitative block 31 is triangular, which prevents the material from piling up on the top of the first quantitative block 31 and causing waste of the material. By designing the top of the first quantitative block 31 into a triangular structure and using the triangular inclined surface to guide the flow direction of the material, when the material contacts the top of the first quantitative block 31, the component force generated by the triangular inclined surface causes the material to slide along the inclined surface to the unloading area, eliminating the material retention space formed by the right-angle structure. This structural feature destroys the mechanical equilibrium conditions of material accumulation by changing the geometric shape of the contact surface, making it impossible for the material to form a stable accumulation layer on the top, thereby avoiding blockage caused by material accumulation and reducing raw material loss caused by material retention during processing.

[0030] The extrusion block 21 is a U-shaped inward-concave structure, and the side surfaces of the eccentric wheel 23 are in contact with the inner surface of the extrusion block 21 to ensure that the material can be better compressed. By designing the extrusion block 21 as a U-shaped inward-facing structure and forming a close fit with the side of the eccentric wheel 23, uniform pressure on the material is achieved. The annular space formed by the U-shaped inward-facing structure can accommodate more materials to be compressed. The eccentric wheel 23 is in continuous contact with the inner surface of the extrusion block 21 during rotation, forming a progressive compression trajectory. The fitting design of the eccentric wheel 23 and the inner wall of the U-shaped structure enables the material to obtain circumferentially uniformly distributed extrusion force during the rotational compression process, avoiding the problem of uneven pressure distribution in traditional planar extrusion structures. This structural coordination method can not only ensure that the material is compressed and formed in the axial direction, but also prevent the material from flying sideways through the circumferential wrapping form, thereby improving the density of the briquette.

[0031] The width of the crushing blade 25 is equal to the width of the cutting groove 37, and the contact surface of the crushing blade 25 and the cutting groove 37 is inclined at an angle of 35°. By precisely defining the coordination relationship between the crushing blade 25 and the support structure, an efficient collaborative mechanism between the blade and the supporting component is established. The width of the crushing blade 25 is designed to be the same as that of the support base plate, ensuring that the blade fully covers the support area during rotation, completely eliminating the hidden danger of material residue caused by local gaps, and at the same time being able to scrape off the material attached to the inside of the cutting groove 37 to avoid material residue.

[0032] Working principle: During the working process, the straw to be briquette is passed from the feed hopper 19 into the interior of the feed bin 18. During the unloading process, the cylinder 27 is used as a power source to accurately drive the connecting column 28 to coordinately drive the connecting frame 29 and the limit plate 30 to perform reciprocating motion, and an alternating abutment mechanism between the limit plate 30 and the first quantitative block 31 and the second quantitative block 32 is used to construct an efficient and stable dynamic unloading channel, ensuring that the material passing amount is accurately regulated during the movement of the limit plate 30, realizing mechanized quantitative unloading operation, and in the unloading process, the reciprocating limit plate 30 will push the straw stuck at the feed port, so that the feeding can be completed without manual unloading, and in the unloading process, it not only ensures the continuity of the unloading process, but also eliminates the safety hazard of the operator contacting the high-speed running parts, significantly improving the production safety and reliability. This innovative design realizes the automation, quantification and safety of material handling through the precise coordination of the mechanical structure, fully demonstrating the technical advantages of the mechanical linkage system. At the same time, the conveying screw 33 arranged on the outside of the third rotating shaft 9 continues to operate, ensuring the continuity and smoothness of material transportation, and completely avoiding the risk of clogging of the feed port easily caused by the traditional manual material feeding method. The material to be briquette is sent to the inside of the extrusion block 21 through the conveying screw 33. At this time, the driving motor 3 serves as the power source, and transmits the power to the first rotating shaft 4, the first pulley 5, the double-groove pulley 8 and the second pulley 10 in sequence, and finally drives the third rotating shaft 9 to rotate; After the third shaft 9 rotates, it drives the first crown gear 12 to rotate. At this time, the first crown gear 12 acts as a driving gear and directly receives the power input of the third shaft 9. The fixed blocks 13 symmetrically arranged on both sides form a rigid support structure, and form a planetary gear transmission relationship with the second crown gear 15 through the meshing column 14. This design enables the second crown gear 15 and the third shaft 9 to achieve coaxial reverse motion. At this time, the reversed second crown gear 15 will drive the extrusion block 21 to rotate through the connecting sleeve 20. At the same time, when the third shaft 9 starts to rotate, the eccentric motion it generates will drive the crushing wheel 24 to perform asymmetric crushing motion inside the second support base plate 35. The unique motion significantly enhances the shearing and squeezing effects on the material. At the same time, multiple groups of crushing knives 25 are rationally distributed along the outer side of the crushing wheel 24, cutting the straw from multiple angles, greatly improving the crushing efficiency. In addition, a scraper 26 is fixedly installed in the middle of the outer surface of the crushing knife 25. During the crushing operation, the scraper 26 will simultaneously scrape off the residual material adhering to the surface of the crushing wheel 24 and the supporting bottom plate, successfully solving the problem of blockage caused by material adhesion. The integrated design of the crushing knife 25 and the scraper 26 combines efficient crushing function with excellent self-cleaning ability, significantly reducing the frequency of equipment downtime and maintenance. After being squeezed by the eccentric wheel 23, the material is squeezed out through the extrusion groove 22 and discharged through the discharge port 36, and the work is completed.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
