Abstract
Description
Technical Field
[0001] This utility model relates to a forage crushing device for livestock breeding, belonging to the technical field of breeding equipment. Background Technology
[0002] In the livestock farming sector, forage is an important feed source for livestock and poultry. Due to its rapid growth rate and rich nutrition, it is widely used in large-scale farms for pigs, dairy cows, laying hens, and broilers. Because natural forage or harvested forage is bulky and has coarse fibers, direct feeding can lead to difficulties in animal consumption and low digestibility. Therefore, it is necessary to use a crushing device to chop the forage to improve feed utilization and farming efficiency.
[0003] Currently, existing forage crushing devices for livestock farming still have many shortcomings in practical applications, as follows:
[0004] Existing equipment typically has an open feed inlet, which causes the feed to easily disperse to both sides when fed in, preventing it from being concentrated and entering the processing area. This not only results in uneven distribution of the feed on the conveyor components but also leads to some feed leaking out from the edges of the conveyor belt, significantly reducing processing efficiency and increasing material waste. The dispersion problem is particularly pronounced when processing long-fiber or fluffy feed.
[0005] Existing pressure roller assemblies are mostly integrated fixed structures, with their gathering range and pressure adjustment relying on mechanical limits or manual intervention. Since different types of forage vary significantly in moisture content, fiber length, and hardness, fixed pressure rollers are ill-suited to meet diverse needs. When the forage is fine and soft, over-compression can easily occur, while coarse and hard forage may suffer from insufficient gathering force, leading to incomplete crushing and directly affecting subsequent cutting quality and the uniformity of the finished feed.
[0006] Existing devices mostly use a single blade or a fixed cutting assembly, lacking a graded processing mechanism. Cutting forage directly without prior cohesion can easily lead to problems such as fiber entanglement in the blade and uneven cut surfaces. Utility Model Content
[0007] This utility model provides a forage crushing device for livestock breeding, which solves the problems of dispersed feeding, poor agglomeration effect, fixed pressure roller structure, insufficient adaptability, and limited cutting efficiency and uniformity in the prior art.
[0008] This utility model provides a forage crushing device for livestock breeding, which includes a shell and an upper cutting component and a lower cutting component located inside the shell. The shell is provided with a transverse conveying component and a gathering pressure roller component that match the shell. The forage is conveyed in the shell by the transverse conveying component. The gathering pressure roller component gathers the forage. The gathering pressure roller component includes a first pressure roller structure and a second pressure roller structure. The second pressure roller structure is located on both sides of the first pressure roller structure and is hinged to the first pressure roller structure. The cross-sectional diameter of the end of the second pressure roller structure away from the first pressure roller structure is larger than the cross-sectional diameter of the first pressure roller structure. The second pressure roller structure includes multiple roller plates. The roller plates are rotated at an angle by a support connecting component.
[0009] The lower cutting component is located below the upper cutting component. The lower cutting component and the upper cutting component are connected by a longitudinal conveying component. The lower cutting component is equipped with a feeding component at its bottom.
[0010] Preferably, the housing is provided with a feed inlet that matches the transverse conveying assembly, and the feed inlet is provided with a baffle that is inclined on both sides of the feed inlet.
[0011] Preferably, the second pressure roller structure further includes a support plate, which is located at the end of the pressure plate away from the first pressure roller structure and is connected to the pressure plate by a sliding connection assembly, wherein the pressure plate and the sliding connection assembly are slidably connected.
[0012] Preferably, the sliding connection assembly includes a first connecting rod and a first connecting block. The roller plate is provided with a first sliding groove that matches the first connecting block. The first connecting block and the first sliding groove are slidably connected. The two ends of the first connecting rod are respectively hinged to the support plate and the first connecting block.
[0013] Preferably, the second pressure roller structure is provided with a ball screw that matches the support connection assembly. The support connection assembly includes a sleeve that is threadedly connected to the ball screw. The sleeve is provided with a plurality of circumferentially distributed second connecting rods. The two ends of the second connecting rods are respectively hinged to the sleeve and the roller plate.
[0014] Preferably, the upper cutting component and the housing are moved up and down by a reciprocating connection component, and the upper cutting component includes a first cutting blade.
[0015] Preferably, the longitudinal conveying assembly includes a feeding plate and a vibration assembly. The top of the feeding plate is hinged to the housing. The housing is provided with a feeding port that matches the feeding plate. The vibration assembly is located on one side of the feeding plate and shakes the feeding plate.
[0016] Preferably, a dispersing pressure roller assembly is provided between the gathering pressure roller assembly and the upper cutting assembly. The dispersing pressure roller assembly includes a third pressure roller structure and a fourth pressure roller structure. The fourth pressure roller structure is located on both sides of the third pressure roller structure and is fixedly connected to the third pressure roller structure. The cross-sectional diameter of the fourth pressure roller structure is smaller than that of the third pressure roller structure.
[0017] Preferably, the roller plate is provided with a protective plate, the protective plate is provided with a plurality of anti-sticking protrusions, and the plurality of adjacent protective plates are connected by a flexible rubber layer.
[0018] Preferably, the first cutter has matching scraper plates on both sides, and the feeding plate has multiple diversion blocks, which are in an inverted V shape.
[0019] The beneficial effects of this utility model are:
[0020] This utility model provides a forage crushing device for livestock farming. By installing an inclined baffle at the feed inlet, it effectively prevents the forage from dispersing to both sides of the casing during input, ensuring that the forage is concentrated and enters the processing area. This avoids uneven distribution of forage on the conveyor components and leakage from the conveyor belt edges, significantly improving processing efficiency and reducing material waste. The second pressure roller structure is located on both sides of the first pressure roller structure, with a design that is thicker at both ends and thinner in the middle. The second pressure roller structure includes multiple roller plates whose angle can be adjusted by ball screws, allowing the pressure roller assembly to adjust the gathering force according to the forage's quantity, fineness, or moisture content, thus adapting to different types of forage. Protective plates are installed on the outside of the roller plates of the second pressure roller structure, filled with a flexible rubber layer to seal the gaps, preventing damp forage from sticking to the pressure roller assembly and preventing forage from entering the pressure roller structure and affecting the rotation of the ball screw, improving the equipment's operational stability and service life. A dispersing pressure roller is added between the gathering pressure roller assembly and the upper cutting assembly. The roller assembly forms a progressive processing flow of first gathering and then loosening. The dispersion roller assembly has a coarse middle and fine ends structure, which generates a lateral dispersing force on the forage during the rolling process, avoiding the forage from clumping together. This provides a looser raw material state for subsequent cutting operations, which helps to improve the uniformity of chopping. The graded cutting design of the upper and lower cutting components is adopted. The upper cutting component cuts the forage into segments, and the lower cutting component further crushes the forage, achieving a finer crushing degree, improving the cutting quality and uniformity of the forage, and meeting the different needs of livestock farming for forage. The top of the feeding plate of the longitudinal conveying component is hinged to the shell, and a vibration component is set below. The vibration component drives the feeding plate to shake through a cam, effectively preventing the residue of forage on the feeding plate and ensuring continuous conveying of forage. A diverting block is set on the feeding plate to evenly distribute the forage to the lower cutting component, avoiding the problems of uneven load and inconsistent coarseness of the cut forage.

The support plate 423 is connected to the roller plate 421 by a sliding connection assembly. The motor drives the support plate 423 to rotate, and the support plate 423 drives the gathering pressure roller assembly 4 to rotate circumferentially through the sliding connection assembly. There are multiple roller plates 421, which are circumferentially distributed around the support plate 423. The ends of the roller plates 421 away from the support plate 423 are hinged to each other. The multiple roller plates 421 are assembled into a trumpet shape to form an adjustment cavity. The ball screw 422 is located inside the adjustment cavity. The ball screw 422 is connected to the multiple roller plates 421 through a support connection assembly.

[0037] The sliding connection assembly includes a first connecting rod 4231 and a first connecting block 4232 that match the roller plate 421. The roller plate 421 is provided with a first groove 4211 that matches the first connecting block 4232 on the inner side near the ball screw 422. The first connecting block 4232 is located inside the first groove 4211 and slides between the first groove 4211 and the first groove 4211. The two ends of the first connecting rod 4231 are respectively hinged to the support plate 423 and the first connecting block 4232.
[0038] The support connection assembly includes a sleeve 4221 that is threadedly connected to the ball screw 422. The sleeve 4221 passes through the ball screw 422 and is threadedly connected to it. The second connecting rod 4222 moves along the axis of the ball screw 422. The ball screw 422 is driven to rotate by a motor. The second connecting rod 4222 is connected to the inner side of the roller plate 421 by the second connecting rod 4222. The two ends of the second connecting rod 4222 are respectively hinged to the roller plate 421 and the sleeve 4221.
[0039] The upper cutting assembly 2 is located at the end of the transverse conveying assembly 12 away from the feed inlet 11. The upper cutting assembly 2 and the housing 1 move up and down through a reciprocating connection assembly 22. The upper cutting assembly 2 includes a first cutter 21, and the reciprocating connection assembly 22 includes a turntable 221 and a movable frame 222. The housing 1 has second sliding grooves on both sides corresponding to the first cutter 21. The first cutter 21 is slidably connected to the second sliding grooves and moves up and down along the second sliding grooves. The reciprocating connection assembly 22 is located on the outside of the housing 1. The blade 21 is fixedly connected to the movable frame 222 through the second sliding groove at both ends. The turntable 221 is located at the end of the movable frame 222 away from the first cutter 21. The movable frame 222 is provided with a waist-shaped groove 2221 that matches the turntable 221. The drive block 223 is provided with an eccentrically set drive block 223. One end of the drive block 223 is fixedly connected to the turntable 221, and the other end of the drive block 223 is located inside the waist-shaped groove 2221 and is slidably connected to the waist-shaped groove 2221. The turntable 221 is driven by a motor.
[0040] The lower cutting component 3 is located below the upper cutting component 2. The housing 1 is provided with a feeding port 13 that matches the lower cutting component 3. The feeding port 13 and the lower cutting component 3 are connected by a longitudinal conveying component 5.
[0041] The longitudinal conveying assembly 5 includes a feeding plate 51 and a vibration assembly 52. The top of the feeding plate 51 is hinged to the housing 1. The vibration assembly 52 is located below the feeding plate 51. The vibration assembly 52 includes a drive shaft 521 and a cam 522. The cam 522 is located at both ends of the drive shaft 521 and is fixedly connected to the drive shaft 521. The cam 522 is in contact with the feeding plate 51. By driving the drive shaft 521 to rotate, the cam 522 is driven to rotate synchronously, and the cam 522 drives the feeding plate 51 to shake.
[0042] The lower cutting assembly 3 includes a feeding frame 31 and a second cutter 32. The feeding frame 31 is fixedly connected to the housing 1. The second cutter 32 is located on both sides inside the feeding frame 31. The two second cutters 32 are symmetrically distributed on both sides and are driven by a motor to rotate in a circular motion to crush the grass. The feeding plate 51 extends to the inside of the feeding frame 31 above the second cutter 32.
[0043] The bottom of the lower cutting assembly 3 is provided with a matching feeding assembly 6. The feeding assembly 6 includes a feeding frame 61 and a threaded conveying structure 62. The threaded conveying structure 62 is located on the 61 and coaxially arranged between the feeding frame 61. The feeding frame 61 is arranged horizontally. The top of the feeding frame 61 is provided with a notch corresponding to the lower cutting assembly 3. The threaded conveying structure 62 is driven to rotate by a motor.
[0044] In use, the grass to be cut is fed into the housing 1 through the feed inlet 11. The baffles 111 on both sides of the feed inlet 11 gather the grass inward to prevent it from moving to the sides of the housing 1. The grass moves into the housing 1 through the transverse conveying assembly 12. During the movement, the gathering pressure roller assembly 4 comes into contact with the grass on top of the transverse conveying assembly 12. The gathering pressure roller assembly 4 is thicker at both ends and thinner in the middle. The motor drives the gathering pressure roller assembly 4 to rotate circumferentially, further gathering the grass on the transverse conveying assembly 12 towards the center. The first cutter 21 ensures that the forage is cut completely. The motor drives the support plate 423 to rotate. The support plate 423 drives multiple roller plates 421 and the first pressure roller structure 41 to rotate synchronously through the first connecting rod 4231, thereby gathering the forage on the transverse conveying assembly 12 inward. During the gathering of the forage, the gathering pressure roller assembly 4 drives the ball screw 422 to rotate through the motor. The ball screw 422 drives the sleeve 4221 to move along the axial direction. The sleeve 4221 drives the second connecting rod 4222 to rotate. The connecting rod 4222 tends to be vertical, and multiple second connecting rods 4222 support multiple roller plates 421, thereby adjusting the diameter of the end of the second roller structure 42 away from the first roller structure 41, so that more forage is gathered towards the center. The gathering force can be adjusted according to the amount or thickness of the forage, thus making it suitable for different types of forage. The motor drives the turntable 221 to rotate, and the turntable 221 drives the movable frame 222 to move up and down along the second slide groove through the drive block 223, thereby realizing the up and down movement of the first cutter 21. 21. The grass is cut into segments. After cutting, the grass falls into the feeding frame 31 through the feeding port 13 and the feeding plate 51. The second cutter 32 is driven by the motor to rotate and further cut the grass. During the feeding process, the motor drives the cam 522 to rotate through the drive shaft 521. The cam 522 drives the feeding plate 51 to sway around the hinge point with the housing 1, thereby preventing grass residue on the feeding plate 51. The grass cut by the lower cutting component 3 is conveyed to one end of the feeding frame 61 through the threaded conveying structure 62 and discharged.
[0045] Compared with the existing design, by setting an inclined baffle 111 on the feed inlet 11, when the forage is fed through the feed inlet 11, the baffle 111 can gather the forage inward, effectively preventing the forage from moving to the sides inside the shell 1, so that the forage can be concentrated into the shell, providing convenience for subsequent processing and improving the efficiency of the feeding process. The second pressure roller structure 42 is located on both sides of the first pressure roller structure 41 and is thick at both ends and thin in the middle. The motor drives the ball screw 422 to rotate, which drives the sleeve 4221 to move along the axial direction, thereby causing the second connecting rod 4222 to drive multiple roller plates 421 to rotate at an angle, adjusting the diameter of the end of the second pressure roller structure 42 away from the first pressure roller structure 41, so that the gathering force can be adjusted according to the amount or thickness of the forage, which is suitable for forage with different characteristics, improving the versatility and adaptability of the device. The motor drives the support plate 423 to rotate, and the support plate 423 drives multiple roller plates 421 through the first connecting rod 4231. The synchronous rotation of the pressure roller structure 41 enables the gathering pressure roller assembly 4 to effectively gather the grass on the transverse conveying assembly 12 inward, ensuring that the first cutter 21 can cut the grass completely, thus improving the cutting quality. The upper cutting assembly 2 and the housing 1 move up and down through the reciprocating connection assembly 22. The motor drives the turntable 221 to rotate, and the turntable 221 drives the movable frame 222 to move up and down along the second slide groove through the drive block 223, thereby realizing the up and down movement of the first cutter 21 to cut the grass. This can better adapt to grass of different thicknesses and shapes, improving the cutting flexibility and effect. The grass is first cut into segments by the upper cutting assembly 2, and then further crushed by the lower cutting assembly 3, which can make the grass reach a finer crushing degree, meet the different needs of livestock farming for grass, and improve the quality and applicability of grass. The cut grass is conveyed to one end of the feeding frame 61 through the threaded conveying structure 62 and discharged.
[0046] Example 2
[0047] In this embodiment, a matching dispersing roller assembly 7 is provided between the gathering roller assembly 4 and the upper cutting assembly 2. The dispersing roller assembly 7 is located above the transverse conveying assembly 12. The dispersing roller assembly 7 includes a third roller pressing structure 71 and a fourth roller pressing structure 72. The fourth roller pressing structure 72 is located on both sides of the third roller pressing structure 71 and is fixedly connected to the third roller pressing structure 71. The dispersing roller assembly 7 is driven to rotate by a motor. A matching limiting disk 73 is provided on the side of the fourth roller pressing structure 72 away from the third roller pressing structure 71. The limiting disk 73 is fixedly connected to the fourth roller pressing structure 72. The third roller pressing structure 71 and the four fourth roller pressing structures on both sides form a shape that is thin at both ends and thick in the middle. The third roller pressing structure 71 is provided with a plurality of circumferentially distributed friction protrusions 711.
[0048] During use, the forage is conveyed by the transverse conveyor assembly 12. The gathering pressure roller assembly 4 gathers the forage on the transverse conveyor assembly 12 towards the center, and then the dispersing pressure roller assembly 7 performs a second rolling press on the forage. Since the diameter of the third rolling structure 71 is larger than the diameter of the fourth rolling structure 72, the dispersing pressure roller assembly 7 is thicker in the middle and thinner at both ends. During the rolling process, the forage on the transverse conveyor assembly 12 is squeezed by the third rolling structure 71, generating a transverse dispersing force and starting to disperse to both sides, providing a loose raw material state for cutting. This avoids the forage from clumping together during the gathering process, which would affect the cutting effect. The progressive processing of gathering first and then dispersing provides a looser raw material state for the chopping operation of the upper cutting assembly 2 and the lower cutting assembly 3, which helps to improve the uniformity of chopping and reduce the clumping of uncut material. The limiting discs 73 on both sides of the fourth rolling structure 72 limit the forage and prevent it from moving to the outside of the transverse conveyor assembly 12.
[0049] Compared with existing technologies, the material is gathered towards the center by the gathering roller assembly 4 and then enters the dispersing roller assembly 7 for secondary rolling. The diameter of the third rolling structure 71 of the dispersing roller assembly 7 is larger than that of the fourth rolling structure 72, forming a structure that is thicker in the middle and thinner at both ends. During the rolling process, the third rolling structure 71 compresses the forage, causing it to generate a lateral dispersing force and begin to disperse to both sides. This provides a looser raw material state for the chopping operations of the upper cutting assembly 2 and the lower cutting assembly 3, effectively preventing the forage from clumping together during the gathering process, thereby improving the uniformity of chopping and reducing the phenomenon of unchopped clumps. The third rolling structure 71 is provided with multiple circumferentially distributed friction protrusions 711, which further enhances the rolling effect, can better disperse the forage, making it looser and creating good conditions for subsequent cutting, thus improving the overall processing efficiency. The fourth rolling structure 72 is provided with limiting discs 73 on both sides, and the limiting discs 73 are fixedly connected to the fourth rolling structure 72. When the forage passes through the dispersing roller assembly 7, the limiting plate 73 effectively limits the forage, preventing it from moving to the outside of the transverse conveying assembly 12 during the roller pressing process. This reduces forage waste, ensures the normal operation of the equipment, and lowers the cost and labor intensity of manual cleaning.
[0050] Example 3
[0051] In this embodiment, a protective plate 424 is fixedly connected to the outside of multiple roller plates 421. The protective plate 424 is provided with multiple anti-sticking protrusions 4241 for preventing sticking with the straw. Multiple adjacent protective plates 424 are fixedly connected to each other through a flexible rubber layer 425, thereby sealing the inside of the second roller structure 42.
[0052] The first cutter 21 has scraper plates 23 fixedly connected to the housing 1 on both sides. The blade surface of the first cutter 21 is slidably connected to the scraper plates 23. The scraper plates 23 are used to scrape away the residue of grass on the first cutter 21.
[0053] The feeding plate 51 is provided with multiple linearly distributed diversion blocks 511. The multiple diversion blocks 511 are fixedly connected to the feeding plate 51. The feeding plate 51 is inverted V shape. The diversion blocks 511 divert the grass on the feeding plate 51 to ensure that the grass falls evenly into the feeding frame 31 and is cut by the second cutter 32.
[0054] During use, the gathering roller assembly 4 gathers the straw towards the center to ensure the cutting effect of the upper cutting assembly 2 and the lower cutting assembly 3. During operation, multiple anti-sticking protrusions 4241 on the protective plate 424 prevent damp straw from sticking to the gathering roller assembly 4, thus affecting its gathering efficiency. The flexible rubber layer 425 fills the gaps between adjacent protective plates 424, preventing straw from entering the second roller structure 42 during the gathering process and affecting the rotation of the ball screw 422. Component entanglement and jamming affect the stability and service life of the equipment. During the cutting process, the upper cutting component 2 scrapes the first cutter 21 with the scraper 23 to ensure the blade surface is clean. The grass cut by the upper cutting component 2 falls into the feeding frame 31 through the feeding plate 51. Multiple diversion blocks 511 on the feeding plate 51 can divert the grass on the feeding plate 51 to ensure that the grass falls evenly into the feeding frame 31 and is then cut by the second cutter 32, avoiding uneven load on the second cutter 32 and inconsistent thickness of the cut grass.
[0055] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
