Description

Technical Field

[0001] This utility model relates to the field of agricultural crop processing technology, specifically a crop crushing device for livestock feed. Background Technology

[0002] Crop pulverizing devices for livestock feed are core mechanical equipment in the feed processing stage. Their core function is to process various crop raw materials such as straw, corn, soybean meal, and rice straw into finely granulated materials that meet the needs of livestock and subsequent feed processing standards. Essentially, this equipment uses mechanical force to break down the intermolecular bonds within the crop raw materials. Through high-speed impact, shearing, compression, or grinding by specific moving parts, the originally large, intact raw materials are broken down and decomposed into pulverized materials that meet production requirements. However, in actual production applications, this type of equipment still has the following problems:

[0003] In daily material feeding operations, straw is the most important processing raw material due to its wide availability and low cost. Currently, straw feeding is mostly done vertically, where operators directly feed the straw into the crushing chamber from the feed inlet at the top of the equipment. However, during the crushing process, the moving parts inside the chamber, such as the auger and crushing hammer, exert continuous pulling and entanglement forces on the straw, causing subsequent straw to be fed into the chamber to be unable to enter smoothly and quickly, often resulting in a "semi-stuck" state. To improve crushing efficiency, operators have to frequently press and comb the stuck straw into the feed inlet by hand to force it into the crushing area. However, during this process, the straw is affected by the pulling force of the parts inside the chamber, which can easily pull the operator's arm into the feed inlet, causing mechanical injury accidents and posing a great threat to the personal safety of the operators.

[0004] Besides straw, production often requires the crushing of large agricultural raw materials such as haystacks and corn cob bales. When these large raw materials are put into the crushing chamber, the movement trajectory and range of action of the crushing components at the bottom of the chamber are limited, preventing them from making full and sufficient contact with the large raw materials immediately. As a result, the crushing operation can only break the large raw materials into several medium-sized small pieces first. After the small pieces are fully dispersed in the chamber, the crushing components can further mix and shear them to finally process them into fine particles that meet the requirements. This process greatly extends the crushing cycle of a single batch of raw materials, reduces the overall processing efficiency of the equipment, and makes it difficult to meet the needs of large-scale feed production for continuous and efficient operation of the equipment.

[0005] Furthermore, after the crushing operation is completed, multiple "cleaning dead corners" often form at the bottom of the chamber. A large amount of crushed fine material will accumulate and stick together here, making it difficult to fall off naturally. In order to avoid the residual material from becoming moldy and deteriorating, affecting the crushing quality of the next batch of raw materials, the operator must thoroughly clean the chamber. However, due to the limited location and space of the cleaning dead corners, the operator cannot complete the cleaning in a conventional way. They can only use tools such as small shovels and brushes to repeatedly scrape and sweep the dead corners. For some dead corners that are difficult to clean, the operator even needs to crawl into the narrow chamber to clean manually. This cleaning method not only consumes a lot of manpower and time, seriously affecting the turnover efficiency of the equipment, but may also increase the probability of accidents such as bumps and scratches because the operator does not have enough safety protection space when working inside the chamber.

[0006] Based on this, the present invention provides a crop crushing device for livestock feed to solve the above problems. Utility Model Content

A crushing rod is fixedly fitted inside each passive synchronous pulley. Multiple crushing blocks are fixedly mounted on each crushing rod. Sliding grooves are opened on both sides of each crushing block. A rectangular groove is opened at the top of each crushing block. A throwing knife is slidably mounted in each rectangular groove. A limiting rod is fixedly mounted at the bottom of each throwing knife and slidably mounted in the sliding groove.

[0011] Preferably, sliding chambers are provided on both sides of the bottom of the box, and a first telescopic plate is slidably installed in each sliding chamber. A second telescopic plate is slidably installed in each of the first telescopic plates. Limit strips are fixedly installed on both the sliding chambers and the first telescopic plates. Threaded sleeves are fixedly installed on each of the second telescopic plates. The same screw, which is rotatably installed on the box, is engaged in the two threaded sleeves. The screw has corresponding positive and negative threads on the threaded sleeves, and a handle is fixedly installed at the end of the screw.

[0012] Preferably, an installation compartment is provided below the sliding compartment, and a storage box is slidably installed in the installation compartment. A handle is fixedly installed on the storage box, and a connecting rod is fixedly installed at the end of each sliding rod.

[0013] Preferably, the box body has a discharge port, a box cover is rotatably installed inside the discharge port, a motor is fixedly installed next to the box body, the motor is connected to a reducer via a conveyor belt, the reducer is connected to a drive auger via a coupling, and bearing seats sleeved on the drive auger and driven auger are respectively installed next to the drive gear and the driven gear.

[0014] The present invention has the following technical effects.

[0015] 1. This utility model incorporates a cutter, sliding rod, limiting frame, and limiting plate.

[0017] 3. This utility model incorporates a sliding chamber, telescopic plate, screw, scraper, and storage box. During cleaning, simply turning the screw handle retracts the telescopic plate, exposing the bottom of the chamber. The sliding rod drives the scraper to automatically remove residual material from dead corners, and the material falls directly into the storage box. There is no need for operators to crawl into the chamber or use tools to repeatedly clean. After disassembling the storage box and emptying the material, it can be reset. This significantly reduces cleaning time and manpower consumption, while also ensuring convenient equipment maintenance and continuous subsequent operations. Attached Figure Description

Detailed Implementation

[0026] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0027] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0028] This utility model relates to a crop crushing device for livestock feed, comprising a housing 1, which is hollow inside with a feed inlet at the top. A driving auger 2 is rotatably mounted horizontally in the lower part of the housing 1's interior. A driven auger 3 is synchronously mounted rotatably beside the driving auger 2 at a suitable distance from it. Both the driving and driven auger 2 have bidirectional spiral blades, a design that allows the raw material entering the housing 1 to be simultaneously subjected to inward convergence and uniform dispersion forces as the augers rotate. Both the driving and driven auger 2 and auger 3 have serrations 4 evenly spaced along the axial direction on their circumferential end faces, the serrations 4 being evenly distributed circumferentially. A large driving gear 5 is fixedly fitted onto one end of the driving auger 2 extending outside the housing 1. Beside gear 5, at the same horizontal level as the driving gear 5, a driven gear 6 is meshed and installed. Both the driving gear 5 and the driven gear 6 are coaxially fixedly fitted with driving pulleys 7. The two driving pulleys 7 are respectively connected to driven pulleys 47 via belts. The driving pulleys 7 and driven pulleys 47 are the same size. The drive shafts 8 are fixedly fitted at the central shaft positions of the two driven pulleys 47. The drive shafts 8 are cylindrical in shape, with one end away from the driven pulleys 47 extending to the upper part of the inner cavity of the housing 1. An eccentric wheel 9 is fixedly installed at the end of the drive shaft 8 extending into the housing 1. A ball bearing 10 is fixedly fitted on the outer side of each eccentric wheel 9. A retaining ring 11 is fixedly fitted on the outer side of the outer ring of the ball bearing 10. A cutter 12 is fixedly installed on the retaining ring 11.

[0029] As an example, a limiting frame 13 is symmetrically fixedly installed at the lower end of the fixed ring 11 in the vertical direction. The limiting frame 13 adopts a "U"-shaped groove metal structure with the groove opening facing downward. A sliding rod 14 is slidably installed inside the groove cavity of the limiting frame 13. A limiting plate 15 is fixedly installed on each sliding rod 14 on both sides of the limiting frame 13. The limiting plate 15 is a circular metal plate with a diameter larger than the width of the groove of the limiting frame 13. The sliding stroke of the sliding rod 14 is limited by the blocking effect of the two limiting plates 15. A fixing plate 16 is sleeved on the outside of the sliding rod 14. A through hole 17 is opened at the center of the fixing plate 16 for the sliding rod 14 to slide, which guides the movement direction of the sliding rod 14 and ensures that the sliding rod 14 always reciprocates in the horizontal direction.

[0030] In practical use, after feeding begins, the operator can put in rod-shaped materials such as straw through the front feed inlet. The active auger 2 extends to one end outside the box 1, driving the active gear 5 to rotate. The active gear 5, through meshing, drives the driven gear 6 on the side to rotate synchronously in the opposite direction. This causes the active auger 2 and the driven auger 3 to rotate synchronously in the opposite direction in the lower part of the inner cavity of the box 1. At the same time, the active gear 5 and the driven gear 6 respectively drive the coaxially fixed drive pulley 7 to rotate. The drive pulley 7 drives the driven pulley 47 to rotate via a belt. The driven pulley 47 drives the drive shaft 8 to rotate. The drive shaft 8 extends to the upper end of the inner cavity of the box 1, driving the eccentric wheel 9 to perform eccentric circular motion. The outer ring of the ball bearing 10 on the outer side of the eccentric wheel 9 moves with it, thereby driving the fixed ring 11 fixedly sleeved on the outer ring of the ball bearing 10 to move up and down. The cutter 12 on the fixed ring 11 moves up and down synchronously. When the operator puts agricultural raw materials such as straw into the upper part of the box 1, the operation is complete. After the feed inlet is opened, the falling straw raw material is first pre-cut into shorter sizes by the reciprocating cutter 12. Then, the smaller pieces fall between the active auger 2 and the driven auger 3, which rotate synchronously in opposite directions. The bidirectional spiral blades on the active auger 2 and the driven auger 3 exert an inward force to gather and evenly disperse the material. Combined with the serrations 4 evenly distributed along the axial direction on the circumferential end face, the material is torn and sheared to achieve thorough crushing. During this process, the "U"-shaped groove limit frame 13 symmetrically installed at the lower end of the fixed ring 11 moves circumferentially with the fixed ring 11. The sliding rod 14 in its groove cavity slides back and forth in the horizontal direction under the drive of the limit frame 13, guided by the central through hole 17 of the fixed plate 16. The circular limit plates 15 on both sides of the limit frame 13 on the sliding rod 14 restrict the stroke of the sliding rod 14 and prevent it from falling off the limit frame 13. This process completes the cutting of straw materials of equal length and effectively solves the technical problem of frequent pressing during feeding.

[0031] As one embodiment, both the active auger 2 and the driven auger 3, extending to their rear ends outside the housing 1, are fixedly fitted with active synchronous pulleys 18. A driven synchronous pulley 19 is rotatably mounted directly above each active synchronous pulley 18. A synchronous belt 20 is fitted between the active synchronous pulleys 18 and the driven synchronous pulleys 19. A crushing rod 21 is fixedly fitted at the central axis position of each driven synchronous pulley 19. The portion of the crushing rod 21 located inside the housing 1 has multiple crushing blocks 22 fixedly installed at equal intervals along the axial direction. The two end faces of each crushing block 22 are... A sliding groove 23 is provided in the horizontal direction. At the same time, a rectangular groove 24 communicating with the sliding groove 23 is provided on the upper end face of the crushed block 22. A throwing knife 25 is slidably installed in the rectangular groove 24. A limit rod 26 is fixedly installed on the lower end face of the throwing knife 25 corresponding to the position of the sliding groove 23 of each crushed block 22. The limit rod 26 is slidably engaged in the sliding groove 23. Through the cooperation between the limit rod 26 and the sliding groove 23, the sliding direction of the throwing knife 25 is restricted, and it is ensured that the throwing knife 25 will not detach from the crushing rod 21 when it rotates with the crushing rod 21.

[0032] In practical use, after feeding begins, the operator can feed block materials such as haystacks into the feed inlet at the rear of the equipment. As the active auger 2 and the driven auger 3 continue to rotate, the active synchronous wheel 18 at its rear always rotates synchronously, stably driving the driven synchronous wheel 19 and the crushing rod 21 to rotate at high speed through the synchronous belt 20. At this time, the crushed blocks 22, which are evenly distributed spirally along the axial direction on the crushing rod 21, rotate synchronously at high speed with the crushing rod 21, crushing the material through high-frequency impact. At the same time, the centrifugal force generated by the high-speed rotation of the crushing rod 21 causes the thin-bladed throwing knife 25, which is slidably installed in the rectangular groove 24 at its upper end, to slide outward along the groove. The limiting rod 26 is fixedly installed at the lower end of the throwing knife 25. As the blade 25 slides synchronously within the sliding groove 23, the sliding direction of the blade 25 is strictly limited to prevent it from deviating, and the blade 25 is also prevented from detaching from the crushing rod 21. Guided by the limiting rod 26, the blade of the blade 25 shears and crushes the material in the box 1. Finally, after being impacted by the crushed blocks 22 and sheared by the blade 25, the material is formed into small particles. After falling naturally along the box 1, the particles fall between the synchronously rotating active auger 2 and the driven auger 3 below for further mixing. This process completes the impact and shearing of large pieces of material, thereby processing large materials into smaller pieces for subsequent processing, effectively solving the technical problem of low crushing efficiency of large materials.

[0033] As one embodiment, symmetrical sliding chambers 27 are provided on the left and right sides of the bottom of the box 1 in the horizontal direction. The sliding chambers 27 have a rectangular cavity structure, are hollow inside and open towards the inner cavity of the box 1. Inside each sliding chamber 27, a first telescopic plate 28 is slidably installed in the horizontal direction. The first telescopic plate 28 is rectangular. On the side of the first telescopic plate 28 away from the sliding chamber 27, there is a rectangular groove with the same length as itself. A second telescopic plate 29 is slidably installed in the groove. The size of the second telescopic plate 29 is adapted to the groove of the first telescopic plate 28. The slide chamber 27 can be completely retracted into the first telescopic plate 28. To prevent the telescopic plate from deviating from the preset track when sliding, the inner side wall of the sliding chamber 27 near the opening and the top surface of the outer end of the first telescopic plate 28 are both fixedly installed with limit strips 30. The second telescopic plate 29 is fixedly installed with threaded sleeves 31, and the internal threads are opposite in direction. The two threaded sleeves 31 are connected to a screw 32. The screw 32 is cylindrical in shape and has positive and negative threads 33 that are respectively adapted to the two threaded sleeves 31. A handle 34 is fixedly installed at the end of the screw 32.

[0034] As an example, an installation compartment 35 is provided below the sliding compartment 27, and its length is the same as that of the sliding compartment 27. A storage box 36 is slidably installed inside the installation compartment 35 in the horizontal direction. A handle 37 is fixedly installed at the center of the end face of the storage box 36 near the outer side of the box body 1. A connecting rod 38 is fixedly installed at the lower end of the sliding rod 14. The connecting rod 38 extends along the height direction of the box body 1 to the bottom area of ​​the box body 1. A scraper 39 is fixedly installed at the end of each connecting rod 38. The scraper 39 contacts and adheres to the bottom surface of the box body 1.

[0035] In practical use, when cleaning the bottom of the housing 1, the operator can use an air gun or broom for cleaning. First, hold the handle 34 at the end of the screw 32 and rotate the handle 34 in the opposite direction to drive the screw 32 to rotate. Since the positive and negative threads 33 on the surface of the screw 32 respectively engage with the threaded sleeves 31 on the second telescopic plates 29 on both sides of the bottom of the housing 1, when the screw 32 rotates, it will drive the two threaded sleeves 31 to move towards each other along the axial direction of the screw 32, thereby pulling the second telescopic plate 29 to retract to the torque of the first telescopic plate 28. Within the groove, the first telescopic plate 28 retracts along the inner wall of the sliding chamber 27, completely exposing the bottom of the housing 1. At this time, because the drive shaft 8 drives the eccentric wheel 9 to perform eccentric circular motion, the fixed ring 11 reciprocates with the ball bearing 10. The sliding rod 14, which is slidably connected to the lower limit bracket 13 of the fixed ring 11, reciprocates synchronously in the horizontal direction, guided by the through hole 17 on the fixed plate 16. The connecting rod 38 fixed at the lower end of the sliding rod 14 moves synchronously with the sliding rod 14, thereby driving... The scraper 39 at the end of the connecting rod 38 reciprocates horizontally. During its movement, the scraper 39's bottom is tightly pressed against the inner wall of the bottom of the housing 1, scraping away the accumulated material inside the equipment. This prevents residual material from sticking to the inner wall of the equipment. The scraped-off residual material falls naturally into the storage box 36 in the installation chamber 35 directly below the sliding chamber 27 due to gravity. After ensuring that there is no material residue at the bottom of the housing 1, the operator holds the handle 37 on the storage box 36 and pushes the storage box 36 along the inner wall of the installation chamber 35. The empty storage box 36 is then pulled out and the residual material collected in the storage box 36 is poured into a designated container. The empty storage box 36 is then slid back into the installation chamber 35 to complete the reset of the storage box 36. This design, through the active scraping of the scraper 39 and the centralized collection of the storage box 36, solves the problem of traditional equipment requiring operators to use tools to clean deep inside the box 1. This not only shortens the cleaning time but also avoids the safety risks of operators working in the narrow box 1, further improving the cleaning efficiency and operational safety of the equipment.

[0036] As an example, the housing 1 has a discharge port 40, and a cover 41 is rotatably installed inside the discharge port 40. The cover 41 can completely cover the discharge port 40 to achieve a seal. A motor 42 is fixedly installed next to the cover 41. The motor 42 is connected to a power supply and a controller. The output shaft of the motor 42 is connected to a conveyor belt 43 through a pulley. The other end of the conveyor belt 43 is connected to the input shaft of the reducer 44, which can convert the high-speed rotation of the motor 42 into a low-speed, high-torque output suitable for the active auger 2. The output shaft of the reducer 44 is fixedly connected to one end of the active auger 2 extending outside the housing through a coupling 45. Bearing seats 46 are respectively installed on the sides of the active large gear 5 and the driven large gear 6, which not only provide additional support for the active auger 2 and the driven auger 3, but also reduce radial runout during rotation.

[0037] The working principle of this utility model is as follows: First, the operator starts the motor 42 connected to the power supply through the controller. The motor 42 drives the input shaft of the reducer 44 to rotate via the conveyor belt 43. The reducer 44 converts the high-speed rotation into low-speed, high-torque rotation, which drives the active auger 2 to rotate through the coupling 45. The active gear 5 on the active auger 2 meshes synchronously, driving the driven gear 6 and the driven auger 3 to rotate synchronously in opposite directions in the lower part of the inner cavity of the housing 1. At the same time, the active gear 5 and the driven gear 6 drive the active pulley 7 to drive the driven pulley 47 to rotate via the belt. Wheel 47 drives drive shaft 8 to rotate. Eccentric wheel 9 at the end of drive shaft 8 drives fixed ring 11 to reciprocate via ball bearing 10. Then, the operator feeds raw materials such as straw into the feed inlet at the front of box 1. As the rod-shaped material falls, it is first pre-cut into short pieces by cutter 12, which reciprocates with fixed ring 11. Limiting bracket 13 at the lower end of fixed ring 11 drives sliding rod 14 to reciprocate horizontally along through hole 17 of fixed plate 16. Limiting plate 15 restricts its stroke. The pre-cut material falls between the synchronously rotating active auger 2 and driven auger 3, moving in both directions. The spiral blades gather and disperse the material, while the saw teeth 4 complete the crushing. Simultaneously, the active auger 2 and the driven auger 3's rear-end active synchronous wheel 18 drive the driven synchronous wheel 19 and the crushing rod 21 to rotate at high speed via the synchronous belt 20. At this time, the operator can feed raw materials such as haystacks into the feed port at the rear of the box 1. The blocky material is crushed by the high-speed impact of the crushing block 22. Centrifugal force causes the spade 25 to slide out along the rectangular groove 24 of the crushing rod 21. The limit rod 26 guides it in the sliding groove 23. The spade 25 shears large pieces of raw material on the inner wall of the box 1, and finally crushes them into small pieces. The block falls into the bottom of the box 1 and continues to be stirred. After the stirring and crushing are completed, the operator opens the box cover 41 on the discharge port 40 to collect the finished product. During cleaning, an air gun or broom is used, and the screw 32 and handle 34 are rotated in the opposite direction to retract the telescopic plate into the sliding chamber 27, exposing the bottom of the box 1. The sliding rod 14 drives the scraper 39 to scrape off the residual material. After being blown and scraped, the residual material falls into the storage box 36 in the installation chamber 35. The operator pulls out the storage box 36, tilts it, and resets it. The operator then rotates the handle 34 in the forward direction to extend the telescopic plate, completing the entire operation process.

[0038] 1. By incorporating a cutter 12, a sliding rod 14, a limiting frame 13, and a limiting plate 15, this utility model allows the cutter 12 to pre-cut the raw material by moving up and down with the fixing ring 11 during feeding. This eliminates the need for operators to manually press and comb the material, keeping them away from the dangerous crushing area throughout the process. Safe feeding can be achieved without additional protective tools, significantly reducing the risk of the operator's arm being caught in the process and improving the safety and convenience of the operation.

[0039] 2. By incorporating a crushing rod 21, crushing blocks 22, and a throwing knife 25, the spiral blades of the active auger 2 and the driven auger 3, in conjunction with the saw teeth 4, crush and impact the raw materials, eliminating the need for repeated crushing in batches, significantly shortening the processing cycle of large raw materials, and significantly improving crushing efficiency and material particle uniformity.

[0040] 3. This utility model incorporates a sliding chamber 27, a telescopic plate, a screw 32, a scraper 39, and a storage box 36. During cleaning, simply turning the screw 32 handle 34 retracts the telescopic plate, exposing the bottom of the box 1. The sliding rod 14 drives the scraper 39 to automatically scrape away residual materials in dead corners, and the materials fall directly into the storage box 36. There is no need for operators to crawl into the box 1 or use tools to repeatedly clean. After disassembling the storage box 36 and emptying the materials, it can be reset. This greatly reduces cleaning time and manpower consumption, while taking into account the convenience of equipment maintenance and the continuity of subsequent operations.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
