Description

Technical Field

[0001] This utility model relates to the field of livestock breeding equipment, specifically to a beef cattle feed crushing device. Background Technology

[0002] In beef cattle farming, forage crushing is a crucial step considering the cattle's physiological structure, nutrient absorption, and overall farming efficiency. As ruminants, beef cattle have a digestive system consisting of the rumen, reticulum, omasum, and abomasum. The rumen harbors a large number of microorganisms that decompose cellulose, hemicellulose, and other substances in the forage through fermentation, providing energy for the cattle. Crushing forage increases the contact area between the forage and rumen microorganisms, promoting fermentation efficiency and making it easier for microorganisms to break down and utilize nutrients, thus improving the digestibility of the forage. Simultaneously, crushed forage is easier for cattle to chew and swallow, reducing feeding difficulty, decreasing energy consumption during feeding, and increasing feed intake.

[0003] According to the authorization announcement number (CN221816220U), a forage crushing device is provided with an inclined limiting plate inside the feed hopper. The limiting plate has an embedded soft filter screen with numerous fine screening channels, which can efficiently separate the crushed forage from the juice. In actual operation, when the crushed material falls onto the surface of the filter screen, the solid forage is intercepted by the mesh, while the juice seeps through the holes into the lower chamber. Thanks to the inclined design of the limiting plate, the intercepted forage slides along the inclined surface under gravity, effectively preventing material accumulation on the top of the filter screen.

[0004] The structure disclosed in this patent has defects in practical applications, specifically as follows: The limiting plate has an embedded soft filter screen, and the crushed straw falls onto the screen surface and must be discharged by its own gravity. When the straw accumulates and causes deformation of the soft filter screen, it changes the inclined guide angle of the filter screen, weakening the component force of the straw sliding along the inclined surface, thus affecting the efficiency of gravity discharge. If the straw accumulates due to high moisture content or fiber entanglement, and the elastic deformation of the soft filter screen exceeds a threshold, it may cause excessive concavity or wrinkling of the screen surface, which in severe cases can lead to filter screen blockage and hinder continuous operation of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a beef cattle forage crushing device, which can address the problem of reduced discharge efficiency and blockage caused by the deformation of soft filter screens due to the accumulation of forage in the prior art. It proposes a solution by designing a forage discharge method that is not dependent on gravity, thereby solving the problem of obstructed discharge and blockage caused by the deformation of soft filter screens due to the accumulation of material.

[0006] This utility model is achieved through the following technical solution: A beef cattle forage crushing device includes: a frame; a crushing chamber mounted on the frame; a crushing assembly at least partially installed within the crushing chamber, capable of crushing forage; a conveying chamber installed at the bottom of the crushing chamber, one end of which communicates with the crushing chamber, and the other end of which has a discharge port; the bottom wall of the conveying chamber having multiple screening channels along its extension direction; a conveying assembly at least partially installed within the conveying chamber, capable of conveying the crushed forage; and a collecting chamber installed at the bottom of the conveying chamber to collect... The collection chamber is connected to multiple screening channels; the conveying assembly includes: a conveying main shaft, both ends of which are rotatably mounted on the inner wall of the conveying chamber; a first motor, which is mounted on the outer wall of the conveying chamber and whose output end is connected to the conveying main shaft; and spiral blades, which are mounted on the conveying main shaft and arranged along the extension direction of the conveying main shaft. The outer surface of the spiral blades is provided with multiple turbulence protrusions along the extension direction. The spiral blades can drive the turbulence protrusions to rotate, and the turbulence protrusions can agitate the crushed grass in the conveying chamber, increasing the contact frequency between the crushed grass and the screening channels.

[0007] Furthermore, in this utility model, an arc-shaped guide plate is installed at the bottom of the conveying cavity, and the conveying cavity and the arc-shaped guide plate slide and guide each other; the arc-shaped guide plate is disposed in the collecting cavity, and multiple unblocking components are installed on the arc-shaped guide plate, which can reciprocate along the extension direction of the conveying cavity; in the cleaning state, the arc-shaped guide plate moves toward the screening channel, and the multiple unblocking components can remove impurities in the screening channel; in the screening state, the arc-shaped guide plate moves away from the screening channel, and the multiple unblocking components are out of the interference range of the screening channel.

[0008] Furthermore, in this utility model, the above-mentioned unblocking component includes: a mounting channel, which is disposed at the top of the arc-shaped guide plate; an unblocking pin, which is slidably assembled on the inner side of the mounting channel, and a guide arc is provided at one end of the unblocking pin facing the conveying cavity; an elastic element, one end of which is connected to the inner wall of the mounting channel, and the other end of which is connected to the unblocking pin; wherein, multiple unblocking components are distributed along the circumferential direction of the conveying cavity, and the spacing between two adjacent unblocking components matches the circumferential arrangement spacing of multiple screening channels.

[0009] Furthermore, in this invention, the bottom end of the conveying cavity is provided with multiple elastic cavities along the circumferential direction; the arc-shaped guide plate can drive multiple unblocking components to move to the corresponding elastic cavities respectively, and the unblocking pin enters the elastic cavity under the reset action of the elastic element, and the elastic element returns to its natural elongation state, avoiding long-term compression leading to elastic decay.

[0010] Furthermore, in this utility model, the above-mentioned crushing component includes: two crushing roller shafts, which are distributed opposite to each other in the crushing chamber, and both ends of the crushing roller shafts are rotatably connected to the inner wall of the crushing chamber; and two second motors, which correspond one-to-one with the two crushing roller shafts, are mounted on the frame, and the output ends of the second motors are connected to the corresponding crushing roller shafts.

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects: 1. This application addresses the problem in the prior art where soft filter screens are prone to reduced discharge efficiency and blockage due to deformation caused by the accumulation of straw. Through a non-gravity-dependent straw discharge design, the forced pushing action of the spiral blades in the conveying assembly is used to make the crushed straw and impurities move directionally along the conveying cavity, avoiding the situation where the filter screen is deformed due to material accumulation, which weakens the gravity discharge efficiency. This ensures continuous and smooth discharge of straw and solves the problem of obstructed discharge and blockage caused by the deformation of soft filter screens due to material accumulation.

[0012] 2. The spiral blades designed in this application are provided with turbulence protrusions on their outer surface. When the spiral blades rotate, the turbulence protrusions exert a mechanical pushing effect on the crushed forage in the conveying chamber, breaking the dense state of the material accumulation, increasing the frequency of contact between the forage and the screening channels, so that the gravel, liquid and other impurities wrapped inside the forage can be exposed and fully contact the screening channels, effectively improving the impurity discharge efficiency, ensuring the purification effect of the crushed forage, avoiding damage to the digestive system of beef cattle caused by accidentally ingesting stones, and controlling the moisture content of the forage to prevent mold growth.

[0013] 3. This application installs an arc-shaped guide plate and a cleaning component at the bottom of the conveying cavity. The reciprocating movement of the arc-shaped guide plate along the extension direction of the conveying cavity drives the cleaning component to periodically clean the screening channels. In the cleaning state, the cleaning component is inserted into the screening channels to remove blockages and impurities; in the screening state, the cleaning component is removed from the screening channel area to avoid interfering with material screening, effectively solving the problem of screening channel blockage caused by long-term operation and ensuring stable and reliable screening efficiency.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model. Example

[0017] Please refer to Figures 1 to 4 This utility model provides a beef cattle forage crushing device. It mainly includes a frame 1, a crushing chamber 2, a crushing component, a conveying chamber 3, a conveying assembly, and a collecting chamber 4. The crushing chamber 2 is mounted on the frame 1, with an open top serving as the working space for forage input and crushing. The crushing component is at least partially located within the crushing chamber 2, crushing the input forage through mechanical action. The conveying chamber 3 is connected to the bottom of the crushing chamber 2, with one end communicating with the crushing chamber 2 and the other end having a discharge port 9. Screening channels 14 are arranged along the extending direction on the bottom wall of the conveying chamber 3. The conveying assembly is at least partially installed within the conveying chamber 3, conveying the crushed forage along the conveying chamber 3 to the discharge port 9. The collecting chamber 4 is located at the bottom of the conveying chamber 3, communicating with multiple screening channels 14 for collecting impurities.

[0018] The workflow is as follows: the forage is fed into the top of the crushing chamber 2, the crushing component crushes the forage, and the crushed product falls into the conveying chamber 3. Then the conveying component operates to drive the crushed product to move along the extension direction of the conveying chamber 3. During this process, impurities such as gravel and liquid fall into the collection chamber 4 through the screening channel 14, while the forage that meets the particle size requirements is intercepted in the conveying chamber 3. The crushed forage can be discharged continuously and smoothly from the discharge port 9, which significantly improves the efficiency and reliability of feed processing and meets the needs of large-scale forage processing in beef cattle farming.

[0019] In some embodiments of this application, the conveying assembly includes a conveying main shaft 10, a first motor 5, and helical blades 11. One end of the conveying main shaft 10 penetrates the side wall of the conveying cavity 3 and forms a dynamic seal connection with the wall of the conveying cavity 3 through a mechanical seal structure; the other end is rotatably mounted on the inner wall of the cavity via a bearing seat. The first motor 5 is mounted on the outer wall of the conveying cavity 3, and the output shaft of the first motor 5 is coaxially connected to the conveying main shaft 10 via a coupling to achieve efficient power transmission. The helical blades 11 are fixed to the conveying main shaft 10 by welding and are arranged spirally along the extension direction of the conveying main shaft 10 to form a continuous conveying channel.

[0020] During operation, the first motor 5 drives the conveying main shaft 10 to rotate, and the conveying main shaft 10 drives the spiral blades 11 to rotate synchronously, causing the crushed grass and impurities to move directionally along the extension direction of the conveying cavity 3. In this process, fine impurities such as gravel and liquid are separated into solid and liquid through the screening channel 14 under the dual action of gravity settling and material fluidization, and fall into the collection cavity 4 below; grass that meets the particle size requirements is conveyed to the discharge port 9 under the forced push of the spiral blades 11.

[0021] It should be noted that the inner wall of the conveying cavity 3 adopts a circular cross-section design, forming a clearance fit with the outer contour of the spiral blade 11. This clearance fit structure, optimized through fluid dynamics, effectively reduces material retention space while ensuring the rotational freedom of the spiral blade 11, preventing the accumulation of forage in the gap between the wall of the conveying cavity 3 and the blade. When the spiral blade 11 rotates, the annular channel formed by the inner wall of the circular cavity and the outer surface of the blade guides the crushed forage to move axially in a laminar flow state, thereby significantly improving conveying efficiency and reducing energy consumption.

[0022] Please refer to Figure 3 In some embodiments of this application, a plurality of turbulence protrusions 13 are uniformly distributed on the outer surface of the spiral blade 11 along the axial extension direction. When the spiral blade 11 rotates with the conveying main shaft 10, the turbulence protrusions 13 rotate synchronously and exert a mechanical agitation on the crushed grass in the conveying cavity 3, thereby increasing the contact frequency between the grass and the screening channel 14 by changing the flow state of the grass.

[0023] Specifically, the structure of the turbulence protrusion 13 periodically disturbs the forage during rotation, breaking the dense accumulation of the material and exposing impurities such as gravel and liquid trapped inside the forage so that they can fully contact the screening channels 14. This effectively solves the problem that impurities cannot contact the screening channels 14 because they are trapped by the forage. Through the dynamic disturbance of the turbulence protrusion 13, this structure enhances the screening effect of the material during the conveying process, significantly improving the efficiency of impurities being discharged into the collection chamber 4 through the screening channels 14, and ensuring the purification effect of the crushed forage.

[0024] It's important to note that sifting out stones and liquids is crucial for beef cattle farming. Removing stones prevents cattle from accidentally ingesting them, thus protecting their digestive system from damage such as scratches, perforations, or intestinal obstruction. Removing liquids effectively controls the moisture content of the feed, preventing mold growth and avoiding diarrhea, poisoning, and other health problems caused by consuming spoiled feed. This approach safeguards beef cattle's diet from both physical and food safety perspectives, while also helping them better absorb nutrients from the feed and reducing the risk of disease during the farming process.

[0025] Please refer to Figures 4 to 7 In some embodiments of this application, an arc-shaped guide plate 15 is installed at the bottom end of the conveying cavity 3, and the conveying cavity 3 and the arc-shaped guide plate 15 form a sliding guide fit. The arc-shaped guide plate 15 is located inside the collecting cavity 4, and multiple unblocking components are arranged on the arc-shaped guide plate 15. During operation, the arc-shaped guide plate 15 can reciprocate linearly along the extension direction of the conveying cavity 3, driving the unblocking components to move synchronously.

[0026] When in cleaning mode, the arc-shaped guide plate 15 moves towards the screening channel 14, allowing the unblocking component to insert and remove blockages from the screening channel 14. When the system switches to screening mode, the arc-shaped guide plate 15 moves in the opposite direction, disengaging the unblocking component from the screening channel 14 area to avoid interfering with normal material screening. This design, through the reciprocating motion of the arc-shaped guide plate 15, enables the unblocking component to periodically clean the screening channel 14, effectively solving the problem of clogging of the screening channel 14 caused by long-term operation and ensuring stable and reliable screening efficiency. The contour of the arc-shaped guide plate 15 fits snugly against the bottom of the conveying cavity 3, and the movement trajectory of the arc-shaped guide plate 15 is always confined within the collection cavity 4, ensuring both effective cleaning and avoiding interference with other components.

[0027] The outer wall of the conveying cavity 3 is provided with a guide tenon 16 along its extension direction, and the outer wall of the arc-shaped guide plate 15 is correspondingly provided with a guide groove 18. The guide tenon 16 is embedded in the guide groove 18 to form a sliding guide structure. This provides rigid guidance for the reciprocating motion of the arc-shaped guide plate 15 along the conveying cavity 3, ensuring that the arc-shaped guide plate 15 maintains its contact accuracy with the bottom of the conveying cavity 3 during translation, and limiting the movement trajectory of the arc-shaped guide plate 15 to the extension direction of the conveying cavity 3, thereby ensuring the cleaning operation of the unblocking component on the screening channel 14.

[0028] Please refer to Figure 1It should be noted that a quick-release inspection door 7 is provided on the front side of the collection chamber 4. This inspection door 7 is sealed to the collection chamber 4 via a sealing strip. Operators can periodically clean the impurities deposited in the collection chamber 4 by opening the inspection door 7, and simultaneously perform maintenance on the arc-shaped guide plate 15 and the unblocking components. Operators can manually adjust the arc-shaped guide plate 15 without obstruction, ensuring the convenience and safety of maintenance operations. The quick-release design of the inspection door 7 improves equipment maintenance efficiency and meets the maintainability design standards for industrial equipment. Please refer to Figure 7 In some embodiments of this application, the unblocking assembly includes a mounting channel 20, an unblocking pin 19, and an elastic element 21 (corrosion-resistant spring). The mounting channel 20 is fixed to the top of the arc-shaped guide plate 15, and the unblocking pin 19 is slidably fitted inside the mounting channel 20. One end of the unblocking pin 19 facing the conveying cavity 3 has a guide arc 12 structure. One end of the elastic element 21 is connected to the inner wall of the mounting channel 20, and the other end is connected to the unblocking pin 19, forming an elastic reset mechanism. Multiple unblocking assemblies are evenly distributed along the circumference of the conveying cavity 3, and the spacing between the multiple unblocking assemblies matches the circumferential distribution spacing of the screening channels 14, ensuring that each unblocking assembly corresponds to a screening channel 14.

[0029] During cleaning operations, the operator drives the arc-shaped guide plate 15 towards the screening channel 14 until the unblocking pin 19 aligns with the screening channel 14. At this point, the elastic element 21 releases its preload, pushing the unblocking pin 19 into the screening channel 14. The unblocking pin 19 then mechanically removes the blockage impurities. When multiple screening channels 14 in adjacent circumferential directions need to be cleaned, the operator continues to advance the arc-shaped guide plate 15, causing the guide arc 12 of the unblocking pin 19 to contact the edge of the screening channel 14. Under the action of the guide arc 12, the unblocking pin 19 overcomes the elastic force and retracts into the mounting groove 20, disengaging from the current screening channel 14, and continues to move to the next cleaning position.

[0030] After the cleaning operation is completed, the operator drives the arc-shaped guide plate 15 away from the screening channel 14, so that the unblocking component is completely removed from the interference area, ensuring the normal operation of the equipment in the screening state. This structure achieves automated cleaning of the screening channel 14 through the synergistic effect of the elastic element 21 and the guide arc 12, which not only ensures the cleaning effect, but also avoids interference with the normal screening process.

[0031] For example, multiple elastic cavities 17 are arranged circumferentially at the bottom end of the conveying cavity 3. When the arc-shaped guide plate 15 moves the unblocking component to the corresponding position of the elastic cavity 17, the unblocking pin 19 is embedded in the elastic cavity 17 under the reset action of the elastic element 21, so that the elastic element 21 returns to its natural elongation state, effectively avoiding the problem of elastic attenuation caused by long-term compression. The elastic cavity 17 is located at the end of the conveying cavity 3 that is not connected to the crushing cavity 2. Its structural design does not penetrate the internal space of the crushing cavity 2, so it will not interfere with the material flow path of the screening process, ensuring that the screening efficiency is not affected.

[0032] Please refer to Figure 2 In some embodiments of this application, the crushing assembly adopts a double-roller counter-crushing structure, specifically including two crushing roller shafts 8 arranged parallel to each other within the crushing chamber 2, and two second motors 6 that drive each crushing roller shaft 8 respectively. Both ends of each crushing roller shaft 8 form a rotatable support structure with the inner wall of the crushing chamber 2, and one end of the crushing roller shaft 8 extends to the outside of the crushing chamber 2 and is equipped with a mechanical seal assembly to prevent material leakage.

[0033] Two second motors 6 are mounted on the frame 1. The output shafts of the second motors 6 are coaxially connected to the extension ends of the corresponding crushing roller shafts 8, forming a dual-input independent drive system. During operation, the two second motors 6 drive the crushing roller shafts 8 to rotate in opposite directions. The forage enters the crushing zone under the action of gravity and roller surface friction, and is coarsely crushed under the action of alternating shearing and extrusion. The crushed particle size can be controlled by adjusting the roller spacing and motor speed.

[0034] It should be noted that the types of forage consumed by beef cattle are diverse and have varying physical properties, and the surface structure of the crushing roller 8 needs to be adapted to these characteristics. Among common forages, ryegrass, Sudan grass, and other grasses have high stalk fiber content and strong toughness, and the connection between the leaves and stalks is prone to tangling; alfalfa, clover, and other legumes have a high degree of lignification in their stalks and their cross-sections are mostly prismatic; corn stalks, wheat stalks, and other straw-type forages have low moisture content, hard texture, and a waxy surface; silage, such as corn silage, has high moisture content, and the fiber structure becomes less tough after fermentation, but it is prone to sticking to the roller surface.

[0035] Based on the above material characteristics, the surface of the crushing roller shaft 8 adopts a structured functional design: the surface of the crushing roller shaft 8 is machined with equidistant spiral grooves to form a directional conveying force for the forage to avoid accumulation. Sawtooth shearing teeth and pyramidal crushing teeth are arranged alternately in the spiral grooves. The sawtooth shearing teeth adopt an acute angle cutting structure to optimize fiber cutting efficiency and the tooth spacing matches the prismatic cross section of legume stalks. The pyramidal crushing teeth adopt a four-sided pyramid tip structure to pierce the waxy layer of straw and guide the moisture of silage through the tooth body guide groove.

[0036] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
