Lake sheep feed grinding and mixing processing device

Abstract

This invention relates to the field of feed processing, specifically to a processing device for crushing and mixing feed for Huzhou sheep. Existing technology involves installing a vibrating motor on the outer wall of the feeding chamber, causing continuous high-frequency vibration throughout the chamber to dislodge the feed lumps. However, long-term operation can easily lead to loosening of equipment connections and fatigue damage. Furthermore, the vibrating motor acts on the entire feeding chamber, failing to provide a directional, strong impact during the initial stage of feed lumps entering the chamber, resulting in limited shaking effect. The proposed Huzhou sheep feed crushing and mixing processing device, through an adjusting rod and gradually heightened abutment ribs, causes the pre-compression of the spring of the vibrating spring to increase linearly along the deflection stroke of the rotating frame. When the rotating frame moves to near the outlet of the pressing unit, i.e., the upper end of the arc-shaped section, the cooperation between the abutment ribs and the locking post maximizes the spring pre-compression, thereby generating a stronger instantaneous rebound force and impact during the initial stage when the compacted feed just enters the feeding chamber.

Description

Technical Field

[0001] This invention relates to the field of feed processing, specifically to a device for crushing and mixing feed for Hu sheep. Background Technology

[0002] In large-scale livestock farming such as Hu sheep, feed usually needs to be processed through pressing, crushing, and mixing to improve its palatability and digestibility.

[0003] The existing processing equipment generally adopts the following process: feed is fed into the pressing unit through the feed inlet, and is squeezed by rollers to form a dense block. The block then falls into the crushing unit through the discharge chamber for cutting, and is finally sent out by the conveying unit.

[0004] In actual production, compacted feed blocks have a dense surface and a certain degree of adhesion. Especially when the feed formula contains ingredients such as moisture, oil, or molasses, the blocks easily adhere to the side walls of the feeding chamber. Furthermore, the compacted blocks have a relatively regular shape, which can cause jamming during processing, resulting in feeding interruptions. These problems not only disrupt the continuity of production but also lead to uneven feeding in the crushing unit, reducing the uniformity of the finished product particle size, and in severe cases, requiring a shutdown for cleaning.

[0005] To alleviate the above problems, the existing technology mainly adopts the following two types of solutions: The first approach involves installing a vibratory motor. Some existing technologies install a vibratory motor on the outer wall of the feeding chamber, causing the entire chamber to vibrate continuously at high frequency to facilitate the material falling off. However, this method has the following drawbacks: The continuous high-frequency vibration generated by the vibratory motor acts on the entire feed processing equipment. It cannot provide a directional strong impact on the initial stage when the material blocks enter the feeding chamber, which is the entry section most prone to adhesion and bridging. Secondly, under long-term continuous operation, high-frequency vibration can easily lead to loosening of the connecting parts of the entire equipment, fatigue cracking of welds, and damage to electrical components, resulting in high maintenance costs and frequent downtime.

[0006] The second approach involves using a motor-driven reciprocating oscillating or linkage-type striking structure. The striking blocks intermittently impact or scrape the sidewalls of the feeding chamber, thus replacing the vibratory motor. However, this method has the following drawbacks: The striking force of this type of structure is usually determined by the fixed stroke of the drive source or the cam lift. The striking force is a constant value throughout the entire swing stroke and cannot be adaptively adjusted according to the different positions of the material block entering the feeding chamber. In particular, it cannot provide a greater instantaneous impact force in the initial adhesion section when the material block just enters the feeding chamber, resulting in poor shaking effect in the initial feeding section. Summary of the Invention

[0007] The purpose of this invention is to provide a processing device for crushing and mixing feed for Huzhou sheep, to solve the problem of feed adhesion at the inlet section where feed lumps are prone to adhesion and bridging in the initial stage of entering the feeding chamber. To achieve the above objective, this invention provides the following technical solution: A processing device for crushing and mixing feed for Huzhou sheep, comprising a processing box, wherein the processing box is arranged sequentially along the feed processing sequence, including an inlet, a pressing unit, a feeding chamber, a crushing unit, and a conveying unit; a crushing and shaking assembly is provided in the feeding chamber, arranged between the pressing unit and the crushing unit; the feeding chamber is enclosed by two opposing side plates, forming a vertical channel for feed passage between the two side plates; each side plate includes an upper arc-shaped section and a lower vertical section; a receiving cavity is reserved between the side plate and the inner wall of the processing box; two sets of crushing and shaking assemblies are provided, corresponding to the arc-shaped sections of the two side plates respectively, and are accommodated in their respective receiving cavities.

[0008] Preferably, each set of crushing and shaking components includes a rotating frame hinged to the inner wall of the processing box. The hinge point of the rotating frame is located on the inner wall of the processing box, and the hinge point coincides with the geometric center of the arc-shaped section of the side plate. A support frame is fixedly installed on the side of the rotating frame facing the side plate. The support frame has locking grooves on two opposite inner side walls. Locking pins are slidably installed in the locking grooves. An installation rod is fixedly connected to the axis perpendicular to the locking pin. A telescopic spring is sleeved on the installation rod. The free ends of the two installation rods are fixedly connected to a shaking spring. At the same time, on the outer wall of the arc-shaped section facing the rotating frame on the side plate, several fixed ribs are evenly distributed along its arc length direction.

[0009] Preferably, the rotating frame has a movable groove along its length, and a movable frame is slidably disposed within the movable groove. A connecting spring connects the movable frame to the end wall of the movable groove. Rotating pins extend outward from both ends of the movable frame, and rotating rollers are mounted on the rotating pins. An arc-shaped guide groove is provided on the inner wall of the processing box to roll with the rotating rollers. An adjusting rod is rotatably connected to the bearing frame. Rotating blocks are respectively provided on the two ends of the adjusting rod. An adjusting frame is hinged between the rotating blocks and the corresponding rotating pins. Several abutting ribs are evenly distributed along the axial direction on the outer circumference of the adjusting rod. The spacing of the abutting ribs is the same as the spacing of the fixed ribs, and the abutting ribs are used to form an abutting fit with the locking pin.

[0010] Preferably, each abutting rib on the adjusting rod has a gradually increasing height structure, with its height increasing sequentially along the direction closer to the pressing unit.

[0011] Preferably, a one-way jet valve is also provided on the vertical section of the side plate, the air inlet of the one-way jet valve is connected to the accommodating cavity, and the air outlet faces the crushing unit.

[0012] Preferably, a rigid bracket is fixed on the processing box, a drive motor is mounted on the top of the rigid bracket, a first rotating rod is coaxially connected to the main shaft of the drive motor, a second rotating rod is provided on the processing box at the pressing unit, the second rotating rod is connected to the first rotating rod by chain drive, the second rotating rod passes through the processing box and is rotatably connected to it, a rotating disk is fixedly provided on its shaft section located in the accommodating cavity, the rotating disk has a cam groove, a reciprocating frame is slidably connected to the inner wall of the processing box, the reciprocating frame cooperates with the cam groove to achieve intermittent up and down movement, a guide frame is provided on the top of the reciprocating frame extending towards the rotating frame, a guide slot is provided on the rotating frame, and a guide roller is provided on the guide frame that rolls with the guide slot.

[0013] Preferably, the pressing unit includes two extrusion rollers disposed at the feed inlet, the gap between the two extrusion rollers being used to mesh and compact the feed. A transmission rod parallel to the second rotating rod is also disposed at the feed inlet, the second rotating rod and the transmission rod being connected by meshing gears. The two extrusion rollers are coaxially fixed on the second rotating rod and the transmission rod, respectively.

[0014] Preferably, the crushing unit includes a crushing frame coaxially fixed to the first rotating rod, and the crushing frame is located below the feeding chamber.

[0015] Preferably, the conveying unit is composed of a screw conveyor, with its feed end located below the crushing frame, for receiving the crushed material and conveying it directionally to the discharge end.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, by setting a crushing and shaking component in the feeding chamber between the pressing unit and the crushing unit, and making it intermittently knock and vibrate against the outer wall of the side plate, the vibration can be effectively transmitted to the inner wall of the side plate, actively shaking off the compacted feed blocks attached thereto. This avoids the dense material blocks formed after the feed is pressed and compacted from getting stuck, sticking or blocking in the feeding channel, ensuring that the material falls smoothly into the crushing unit.

[0017] In this invention, by adjusting the rod and the gradually increasing height of the abutment rib, the pre-compression of the telescopic spring of the shaking spring increases linearly along the deflection stroke of the rotating frame. When the rotating frame moves to near the outlet of the pressing unit, that is, the upper end of the arc section, the cooperation between the abutment rib and the locking post maximizes the pre-compression of the spring. This generates a stronger instantaneous rebound force and impact in the initial stage when the compacted feed just enters the feeding chamber, ensuring that the feed block is effectively shaken off as soon as it enters the feeding chamber, thus improving the shaking effect in the initial feeding stage.

[0018] In this invention, the striking force is adjusted by an independently set adjusting rod and abutting rib. Because the fixed rib is short in height, the climbing stroke of the vibrating spring is short, and feed dust is not easy to accumulate in the gap. This avoids the wedge-shaped self-locking and jamming phenomenon caused by dust intrusion in the traditional long rib structure. At the same time, the total compression stroke of the spring is controlled by the abutting rib, rather than relying on the height of the fixed rib. The compression stroke is shorter, which reduces the stress relaxation of the spring during long-term use and extends the service life of the telescopic spring and the entire vibrating assembly.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example Please see Figures 1 to 12 The present invention provides a technical solution: a Hu sheep feed crushing and mixing processing device, including a crushing and shaking component 2, which is suitable for the feeding stage in the feed processing process, and solves the problems of feed blocks being stuck and sticking in the feeding chamber 12 after being pressed and compacted, so as to realize the function of continuous and stable auxiliary feeding.

[0023] The crushing and shaking component 2 is integrated into the processing box 1 in the feed processing process. The processing box 1 is arranged in sequence along the feed processing sequence, including the feed inlet 11, the pressing unit 5, the feeding chamber 12, the crushing unit 6, and the conveying unit 7. The crushing and shaking component 2 is located in the feeding chamber 12 and is arranged between the pressing unit 5 and the crushing unit 6. The feed enters the pressing unit 5 through the feed inlet 11, and after rolling and compaction, it forms a dense block. Then, the block falls into the crushing unit 6 through the feeding chamber 12 for cutting and crushing. The crushed material is output by the conveying unit 7. The crushing and shaking component 2 is used to apply intermittent shaking force to the compacted block to prevent the block from sticking to the side wall of the feeding chamber 12 and to help it fall smoothly into the crushing unit 6.

[0024] Specifically, the feeding chamber 12 is surrounded by two opposing side plates 13, and the two side plates 13 form a vertical channel for the feed to pass through. Each side plate 13 includes an upper arc-shaped section 131 and a lower vertical section 132. A receiving cavity 133 is reserved between the side plate 13 and the inner wall of the processing box 1. The crushing and shaking assembly 2 is provided in two sets, corresponding to the arc-shaped sections 131 of the two side plates 13 respectively, and is accommodated in their respective receiving cavities 133. Each set of crushing and shaking components 2 includes a rotating frame 21 hinged to the inner wall of the processing box 1. The hinge point of the rotating frame 21 is located on the inner wall of the processing box 1, and the hinge point is consistent with the geometric center of the arc section 131 of the side plate 13. A support frame 22 is fixedly installed on the side of the rotating frame 21 facing the side plate 13. The two opposite inner side walls of the support frame 22 are provided with snap-fit ​​grooves 23. A snap-fit ​​post 24 is slidably installed in the snap-fit ​​groove 23. An installation rod 25 is fixedly connected to the axis perpendicular to the snap-fit ​​post 24. A telescopic spring 26 is sleeved on the installation rod 25. The free ends of the two installation rods 25 are fixedly connected to a shaking spring post 27. At the same time, on the outer wall of the arc section 131 facing the rotating frame 21 of the side plate 13, a number of fixed ribs 28 are evenly distributed along its arc length direction. When the rotating frame 21 is driven to deflect along the arc section 131, the bearing frame 22 drives the shaking spring 27 to move synchronously. On this moving path, the shaking spring 27 makes intermittent contact with each fixed rib 28 in turn. When in contact, the fixed rib 28 forces the shaking spring 27 to overcome the elastic force of the telescopic spring 26 and contract into the bearing frame 22. When the contact is broken, the telescopic spring 26 releases the elastic force, causing the shaking spring 27 to strike the outer wall of the side plate 13 instantly, thereby transmitting the vibration to the inner wall of the side plate 13 and shaking off the compacted feed attached to it.

[0025] Furthermore, a movable slide groove 3 is provided on the rotating frame 21 along its length direction. A movable frame 31 is slidably arranged in the movable slide groove 3. A connecting spring 32 is connected between the movable frame 31 and the end wall of the movable slide groove 3. Rotating pins 33 are provided at both ends of the movable frame 31. Rotating rollers 34 are installed on the rotating pins 33. An arc-shaped guide groove 35 is provided on the inner wall of the processing box 1 to roll with the rotating rollers 34. An adjusting rod 36 is rotatably connected to the bearing frame 22. Rotating blocks 37 are respectively provided on the two ends of the shaft section of the adjusting rod 36. An adjusting frame 38 is hinged between the rotating blocks 37 and the corresponding rotating pins 33. Several abutting ribs 39 are evenly distributed along the axial direction on the outer circumference of the adjusting rod 36. The spacing of the abutting ribs 39 is the same as the spacing of the fixed ribs 28, and the abutting ribs 39 are used to form an abutting fit with the locking post 24. When the rotating frame 21 deflects, the rotating roller 34 rolls along the arc-shaped guide groove 35, forcing the moving frame 31 to slide within the moving slide groove 3 against the force of the connecting spring 32. The sliding of the moving frame 31 causes the rotating block 37 to drive the adjusting rod 36 to deflect through the adjusting frame 38. When the rotating frame 21 moves to the upper end of the arc-shaped section 131 near the pressing unit 5, the abutting rib 39 on the adjusting rod 36 gradually contacts the locking post 24. At this time, the shaking spring 27 is just at the critical point of contact with the fixed rib 28. Due to the additional compression of the locking post 24 by the abutting rib 39, the pre-compression of the telescopic spring 26 increases, which increases the instantaneous rebound force when the shaking spring 27 separates from the fixed rib 28, thereby generating a stronger shaking impact at the outlet of the pressing unit 5, ensuring that the compacted feed is effectively shaken off as soon as it enters the feeding chamber 12.

[0026] As a further preferred embodiment, the fixed rib 28 is configured to have a constant and short height, and its function is limited to contacting and disengaging from the vibrating spring 27, without undertaking the function of adjusting the striking force. The striking force is adjusted by an independently set adjustment rod 36, the abutting rib 39 and the vibrating spring 27. The abutting ribs 39 distributed on the adjusting rod 36 adopt a gradually changing height structure, and their height increases sequentially along the direction close to the pressing unit 5, so that the pre-compression of the telescopic spring 26 increases linearly along the deflection stroke of the rotating frame 21, thereby achieving a gradual enhancement of the shaking force of the side plate 13. The fixed rib 28 has a constant height and is relatively short, and the climbing stroke of the shaking spring 27 is short. Feed dust is not easily accumulated in the gap, which effectively avoids wedge self-locking and jamming caused by long climbing stroke. The pre-compression of the telescopic spring 26 is controlled by the abutting rib 39. Its total compression stroke is less than the compression stroke achieved by increasing the length of the fixed rib 28, which reduces the stress relaxation of the spring during long-term use and extends the service life of the telescopic spring 26 and the shaking component. Even if the fixed rib 28 is slightly worn during use, it will not affect the stability and adjustability of the shaking force. The above structure ensures a strong shaking effect while improving the reliability of the device and the convenience of maintenance.

[0027] In this embodiment, a one-way jet valve 310 is also provided on the vertical section 132 of the side plate 13. The air inlet of the one-way jet valve 310 is connected to the accommodating cavity 133, and the air outlet faces the crushing unit 6. When the rotating frame 21 reciprocates within the accommodating cavity 133, air is injected into the crushing unit 6 via the one-way jet valve 310 to help blow away the fine powder material adhering to the inner wall of the vertical section 132.

[0028] In this embodiment, a rigid support 4 is fixed on the processing box 1, and a drive motor 41 is installed on the top of the rigid support 4. A first rotating rod 42 is coaxially connected to the main shaft of the drive motor 41. A second rotating rod 43 is provided on the processing box 1 at the pressing unit 5. The second rotating rod 43 and the first rotating rod 42 are connected by a chain 44. The second rotating rod 43 passes through the processing box 1 and is rotatably connected to it. A rotating disk 45 is fixedly provided on its shaft section located in the accommodating cavity 133. A cam groove 46 is provided on the rotating disk 45. A reciprocating frame 47 is slidably connected to the inner wall of the processing box 1. The reciprocating frame 47 cooperates with the cam groove 46 to achieve intermittent up and down movement. A guide frame 48 is provided on the top of the reciprocating frame 47 extending toward the rotating frame 21. A guide groove 49 is provided on the rotating frame 21. The guide groove 49 is provided on the rotating frame 21 and is an independent channel structure from the moving slide 3. The guide groove 49 is used to roll and cooperate with the guide roller 410 on the reciprocating frame 47 to drive the rotating frame 21 to reciprocate around its hinge point. The moving slide 3 is used to accommodate the moving frame 31, so that the moving frame 31 slides along the length direction of the rotating frame 21 under the constraint of the arc-shaped guide groove 35 during the deflection of the rotating frame 21. The guide frame 48 is provided with a guide roller 410 that rolls and cooperates with the guide groove 49. When the drive motor 41 is running, the first rotating rod 42 drives the second rotating rod 43 to rotate synchronously through the chain 44. The second rotating rod 43 drives the two rotating disks 45 to rotate. The cam groove 46 on the rotating disk 45 drives the reciprocating frame 47 to perform intermittent lifting and lowering motion. The guide frame 48 at the bottom of the reciprocating frame 47 rolls in the guide slot 49 of the rotating frame 21 through the guide roller 410, thereby driving the rotating frame 21 to reciprocate with a curvature that matches the arc section 131 of the side plate 13.

[0029] In this embodiment, the pressing unit 5 includes two extrusion rollers 51 disposed at the feed inlet 11. The gap between the two extrusion rollers 51 is used to mesh and compact the feed. A transmission rod 52 parallel to the second rotating rod 43 is also disposed at the feed inlet 11. The second rotating rod 43 and the transmission rod 52 are connected by a meshing gear 53. The two extrusion rollers 51 are coaxially fixed on the second rotating rod 43 and the transmission rod 52, respectively. When the second rotating rod 43 rotates, it drives the transmission rod 52 to rotate in the opposite direction synchronously through the meshing gear 53, so that the two extrusion rollers 51 rotate relative to each other and continuously extrude and shape the incoming feed.

[0030] In this embodiment, the crushing unit 6 includes a crushing frame 61 coaxially fixed on the first rotating rod 42, and the crushing frame 61 is located below the feeding chamber 12; When the first rotating rod 42 rotates, it drives the crushing frame 61 to rotate at high speed, cutting and crushing the feed that has been compacted and shaken off and fallen into the crushing area, processing it into small particles or fragments.

[0031] In this embodiment, the conveying unit 7 is composed of a screw conveyor 71, with its feed end located below the crushing frame 61, for receiving the crushed material and conveying it directionally to the discharge end.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
