[0030] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. The illustrative implementation methods and descriptions of the embodiments of this disclosure are only used to explain the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0031] like Figure 1As shown, the forage grinder for cattle breeding of the present application comprises a feeding hopper 1, a flow guide plate 2, a crushing cutter head 3, a screening mesh plate 4, a discharge box 5 and a support 6, each component is cooperated with each other through reasonable installation position and structure design, and the high-efficient forage crushing operation is realized.

[0032] The forage grinder is provided with a feeding hopper 1 for containing the forage to be processed and guiding the forage to the internal device. The feeding hopper 1 is in the structure of wide at the top and narrow at the bottom, and the top opening design can accommodate a larger amount of forage, and the inner wall is a smooth surface or processed by polishing process, so as to reduce the friction between the forage and the inner wall during falling. The feeding hopper 1 can be made of high-strength stainless steel material to meet the requirements of wear resistance and corrosion resistance, while maintaining the reliability of long-term operation.

[0033] The flow guide plate 2 is arranged below the feeding hopper 1 for further improving the inflow path of the forage and preventing accumulation. The surface of the flow guide plate 2 has a corrugated protrusion 21 structure which is processed by stamping process, which can reduce the sliding resistance between the forage particles and make the forage evenly spread into the subsequent equipment. In addition, the side of the flow guide plate 2 is provided with an inwardly curved arc-shaped flange 22 structure, which not only can protect the edge of the flow guide plate 2 from mechanical damage, but also can re-direct the scattered forage to the central area. In order to ensure the uniformity of forage distribution, a plurality of uniformly distributed guide grooves 23 are opened at the bottom of the flow guide plate 2, which are cut into shape by machining method, effectively dispersing the forage flow direction and avoiding the phenomenon of excessive accumulation in a single direction.

[0034] The crushing cutter head 3 is located below the flow guide plate 2 (for details, please refer to Figure 2 ), which is mainly used for efficient cutting and crushing of forage. The crushing cutter head 3 is composed of a group of high-speed rotating blades, each blade is firmly connected to the shaft by riveting or welding technology to ensure the structural stability under high load working condition. According to the actual use requirement, the shape of the blade can be designed as sawtooth or straight line, and the rotating speed is usually adjusted between 2000-3000 revolutions / minute under the drive of the motor, so as to realize the high-efficient crushing performance. The cutter head is also equipped with a protective cover structure to avoid splashing or safety problems during the crushing process.

[0035] The screening mesh plate 4 is installed below the crushing cutter head 3 (for details, please refer to Figure 6), mainly used for screening forage particles that meet the specified size requirements. The screening mesh plate 4 is made of a solid and corrosion-resistant metal material, with a surface densely covered with uniformly arranged small holes or a grid structure, and the specific specifications can be determined according to the target particle size of the crushed forage. For example, if forage particles with a particle size of not more than 5 mm are required, a screen with a hole diameter of 5 mm can be selected; for finer requirements, a more fine screen hole design (such as 2 mm hole diameter) can be selected. By adjusting the tension of the screen, the service life can be improved and the screening accuracy can be ensured.

[0036] The discharge box 5 is connected to the screening mesh plate 4 and is used to collect the crushed forage particles that meet the requirements and discharge them into an external container. The discharge box 5 generally has a large volume design to facilitate the storage of a certain amount of material. In order to optimize the speed and smoothness of the forage flow, a conical or horn-shaped flow guide component can be installed at the outlet to further prevent problems caused by local clogging. At the same time, control valves or flow meters and other components can be added as needed to allow users to monitor the dynamic information of the discharge amount.

[0037] The support 6 serves as the support base of the crusher and plays a key role in fixing the entire structure. The frame body is made of rectangular steel tubes assembled and welded together, and the arrangement of reinforcing ribs enhances the overall bending strength and vibration resistance. In addition, the support 6 is equipped with rubber pads or hydraulic buffer devices at the bottom end to effectively reduce the transmission of vibrations to the ground during equipment operation, ensuring stable operation of the entire machine and reducing the likelihood of deviation or tilting.

[0038] Through the above structural design and component cooperation, a forage crusher for cattle breeding solves the technical problems of how to avoid forage clogging and improve the processing capacity. Among them, the large capacity and smooth inner wall of the feed hopper 1 reduce the risk of initial clogging, while the unique corrugated protrusions, arc-shaped flanges 22 and guide grooves 23 of the flow guide plate 2 significantly optimize the uniformity of forage distribution and reduce the probability of concentrated pressure. At the same time, the high-speed rotating crushing cutter head 3 quickly completes the initial processing task of the forage, and the high-efficiency and precise screening mesh plate 4 further improves the screening efficiency, thereby promoting the smoothness and productivity of the overall process. Therefore, this structure significantly improves the forage processing capacity of the equipment while reducing maintenance costs and downtime probability.

[0039] As Figure 3As shown, in one embodiment, the bottom outlet of the feed hopper 1 of the forage grinder for cattle breeding of the application adopts a conical structure to realize more uniform transition and conveying of the forage to be crushed to the guide plate 2. The conical structure guides the forage to flow gradually by reducing the cross-sectional area of the outlet. To prevent the forage from rotating or blocking due to accumulation during the process of entering the guide plate 2, rib 7 structures are arranged on the inner surface of the conical structure in an axial direction. The specific position of the rib 7 extends along the inner wall of the feed hopper 1 to the outlet end, and reduces the excessive friction between the forage and the conical inner wall and between the forages by uniform arrangement. This arrangement can make the forage smoothly slide into the guide plate 2 area, thereby ensuring smooth subsequent crushing operation of the equipment.

[0040] For example, the rib 7 can be designed as a group of long strip-shaped protrusions arranged at equal intervals and perpendicular to the outlet direction. Specifically, a metal or engineering plastic material with certain wear resistance can be selected, and the rib 7 is fixed to the inside of the feed hopper 1 by buckling or welding, so that it is stably connected and plays the expected guiding function. At the same time, the conical part of the feed hopper 1 is in direct communication with the guide plate 2, further improving the overall layout rationality of the device.

[0041] As shown, Figure 4 In one embodiment, the surface of the guide plate 2 of the forage grinder for cattle breeding of the application is designed with a unique corrugated protrusion 21. To further reduce the friction generated by the forage during movement, the edge top of the corrugated protrusion 21 is specially optimized. Specifically, the edge top is treated with a hemispherical chamfer structure 8. This structure can effectively reduce the frictional resistance when the forage contacts the guide plate 2, so that the forage can more smoothly slide along the preset path to the crushing area. The hemispherical chamfer structure 8 reduces the possibility of material blockage by uniform transition, improving the overall smoothness of forage conveying.

[0042] For example, during the manufacturing process of the guide plate 2, the regular corrugated protrusion 21 is first formed by mold forming or machining, and then the edge of the corrugated protrusion 21 is accurately treated by numerical control equipment or special grinding tools to generate a hemispherical chamfer profile. The entire manufacturing process needs to ensure the consistency of the guide plate 2 as a whole, so that it can be accurately installed below the feed hopper 1 and smoothly cooperate with the subsequent components.

[0043] As shown, Figure 4As shown, in one embodiment, a flexible anti-blocking gasket 9 is arranged inside the guide plate 2 of the forage grinder for cattle breeding. The flexible anti-blocking gasket 9 is installed in the inner area of the arc-shaped flange 22 of the guide plate 2 and is stably connected to the arc-shaped flange 22 through a special bonding process or buckle form. The flexible anti-blocking gasket 9 has good elasticity and wear resistance and can avoid blockage caused by accumulation of forage during entry into the guide plate 2. Since it is located inside the arc-shaped flange 22, the flexible anti-blocking gasket 9 can play a certain buffering role when guiding forage and reduce the blocking phenomenon caused by friction.

[0044] Specifically, for example, the gasket made of flexible materials such as rubber or polyurethane can be pre-processed into a component conforming to the curvature shape of the arc-shaped flange 22, and then fixed to the inner side wall of the arc-shaped flange 22 using an embedded design during assembly. The flexible anti-blocking gasket 9 is matched in size and closely fitted through reasonable structure, which neither affects the forage flow efficiency of the overall equipment nor provides functional support to effectively prevent blockage. In addition, to ensure reliability, the gasket can also be provided with a small guide groove 23 structure to match the functional characteristics of the guide plate 2.

[0045] As shown, Figure 4 In one embodiment, the forage grinder for cattle breeding of the present application is further provided with a material blocking block 10 below the guide plate 2 to achieve effective guidance and dispersion of forage with different flow directions. Specifically, the material blocking block 10 is arranged between the adjacent guide grooves 23 at the bottom of the guide plate 2 and is used to adjust the falling state of the forage after flowing out of the guide grooves 23. This feature ensures that the crushing cutter head 3 can more uniformly contact the forage and improve the cutting efficiency. The number, position and distribution of the guide grooves 23 between the material blocking blocks 10 are closely matched to adapt to different types and flow rates of forage.

[0046] Specifically, the material blocking block 10 is fixedly connected to a specific area at the bottom of the guide plate 2 and can be designed in the shape of an inclined surface or an arc surface, etc. according to the actual forage flow situation. For example, when the forage is relatively dense, an inclined surface-shaped material blocking block 10 with a larger inclination angle can be used to increase the dispersion capacity; while when processing light forage, an arc surface shape can be selected to reduce the reverse force when the forage is impacted. The material blocking block 10 is stably installed on the guide plate 2 through bolt fixation or other forms of connecting devices and maintains a proper spacing with the guide grooves 23 to complete the functional requirements of forage guidance and dispersion. Technically, the material blocking block 10 can be manufactured by mold injection or metal cutting processing and precisely assembled at the corresponding position to ensure stable performance.

[0047] As shown, Figure 5As shown, in one embodiment, the deflector 2 of the forage grinder for cattle breeding of the present application is stably connected with the grinding cutterhead 3 through specific fixing and adjusting structures. A special installation form is designed at the bottom of the deflector 2, which is connected with the shell of the grinding cutterhead 3 through a threaded rod assembly 11. This design not only ensures the stability of the two during equipment operation, but also adjusts the positional relationship of the deflector 2 relative to the grinding cutterhead 3, optimizes the distribution and conveying effect of forage on the deflector 2. Specifically, the threaded rod assembly 11 is composed of a threaded rod with adjustable length and its matching locking component, which tightly presses the deflector 2 on the shell of the grinding cutterhead 3.

[0048] For example, when the horizontal position of the deflector 2 needs to be adjusted, the locking component on the threaded rod assembly 11 is loosened, allowing the threaded rod to rotate to a certain extent to change the horizontal spacing or angle of the deflector 2. Then the locking component is tightened again to fix the newly adjusted position, so that the deflector 2 can adapt to different working conditions and ensure that the forage can be more efficiently conveyed to the grinding cutterhead 3 for processing.

[0049] As shown, Figure 5 In one embodiment, a set of buffer devices is arranged in the connection area between the deflector 2 and the grinding cutterhead 3 of the forage grinder for cattle breeding of the present application to solve the operation problem under certain conditions. The buffer device is mainly a plurality of buffer spring seats 12, which are distributed at the bottom of the deflector 2 and extend to the corresponding installation position at the top of the grinding cutterhead 3. The design of the buffer spring seat 12 forms a dynamically adjustable space interval between the deflector 2 and the grinding cutterhead 3, which allows a certain space change to relieve the compression force when there is too much or too large forage. At the same time, this connection method can avoid the problem of stagnation caused by excessive compression of forage.

[0050] More specifically, these buffer spring seats 12 are made of high-strength elastic material and are fixed at the top of the grinding cutterhead 3 and the bottom of the deflector 2 by welding or fasteners, and the distribution position is accurately calculated to match the forage flow path. When the equipment is started, the forage falling from the feed hopper 1 will generate pressure on the buffer device, and the spring seat will be appropriately compressed or reset according to the actual force condition to ensure that the internal passage is always unblocked.

[0051] For example, the buffer effect can be customized by selecting a spring material with a suitable hardness coefficient to adapt to changes in different types of forage or flow requirements. In this process, the relative spacing range of the deflector 2 and the grinding cutterhead 3 can be set within 2-5 cm according to test data, ensuring that the optimal operating state is maintained.

[0052] As shown, Figure 7As shown, in one embodiment, a specially designed device is added inside the discharge box 5 of a cattle feed shredder according to this application to improve feed discharge efficiency and reduce clogging. In this feed shredder, the discharge box 5, located below the screening screen 4, collects the shredded feed that has passed through the screening screen 4 and meets the requirements, and further discharges it into the external environment. To enhance feed discharge capacity, a rotating guide impeller 15 structure specifically designed for agitating the feed is added inside the discharge box 5. This rotating guide impeller 15 is installed inside the discharge box 5 near the outlet end and can rotate at high speed driven by the machine power during operation.

[0053] The rotary guide impeller 15 consists of multiple evenly distributed arc-shaped blades, which are securely welded or integrally formed to the central drive shaft, ensuring sufficient rigidity and stability of the overall structure. The rotary guide impeller 15 is positioned directly in front of the discharge port to facilitate rapid mixing and dispersion of the soon-to-be-discharged forage. Furthermore, the central drive shaft is connected to the main drive system of the equipment, utilizing existing mechanical power to drive its rotation. For example, when power from the main drive system is transmitted to the rotary guide impeller 15, its blades, through high-speed rotation, create a vortex effect in the surrounding air, further propelling the forage towards the discharge port.

[0054] Specifically, stable output of the drive system can be ensured through belt drive or gear meshing. The blade angle and number can be flexibly adjusted according to the target discharge rate. For example, a structure with three to five blades at a certain tilt angle can be selected to minimize the probability of clogging without affecting the function of other components.

[0055] like Figure 1 As shown, in one embodiment, a vibration device 16 is provided on the support 6 of a cattle feed shredder near the guide plate 2. This vibration device 16, through a specific structure and by adjusting different frequencies, generates vibration force that acts on the guide plate 2 area, thereby allowing the feed stagnant on the guide plate 2 to move more smoothly downwards. Specifically, this design can effectively solve the problem of material blockage caused by dampness or unusual shapes, and ensure the continuous and stable operation of the entire equipment. Since the guide plate 2 is one of the key paths in the entire feed guiding system, material accumulation is prone to occur above it; therefore, adding a vibration device 16 to this area can compensate for the shortcomings of traditional designs.

[0056] The vibration device 16 is fixed on the bracket 6 near the bottom of the deflector 2, and is connected to the bracket 6 by fasteners, while leaving appropriate movement space to avoid damaging other components when generating vibration force. The device itself is usually composed of a motor-driven unit and a spring suspension system, in which the spring plays a role in buffering and adjusting the frequency, and the driving unit provides the energy source for the overall vibration. This layout not only ensures that the vibration effect is directly applied to the area near the deflector 2, but also minimizes the interference with the operation of other components.

[0057] For example, a small vibration motor can be used as the core component installed in the designated area, and works with an external controller to regulate the working frequency. By changing the input electrical signal waveform or voltage parameters, the motor generates the required oscillation amplitude and direction, and transmits power to the relevant parts to improve the forage conveying process.

[0058] As shown in Figure 3 In one embodiment, the feed hopper 1 of the forage grinder for cattle breeding of the present application has a built-in heating function design, specifically a special heating pipe 17 structure is provided on the side wall of the feed hopper 1. The heating pipe 17 is embedded in the inside of the side wall of the feed hopper 1, and applies heat to the forage entering it by conduction. This design aims to avoid the problem of surface adhesion and blockage caused by low temperature when high humidity forage is introduced, so as to ensure that the material can continuously and uniformly flow into the subsequent device. The heating pipe 17 is made of materials with good thermal conductivity, such as metal pipes or composite structures, and is connected to an external constant temperature control power module to maintain appropriate heat output.

[0059] For example, the heating pipe 17 is installed in the cavity of the side wall of the feed hopper 1, which can be a serpentine pipe with a winding distribution to increase the contact area with the side wall, or a spiral winding design. For example, the pipe is connected to the water inlet pipe and the water outlet pipe interface at both ends, and sealing measures are taken to prevent heat loss and gas leakage risk. Further, in order to improve the energy utilization efficiency and uniformity, a layer of heat insulation protective layer can be additionally attached to the inner surface of the feed hopper 1. In this way, this feature not only meets the needs of high-moisture forage processing, but also ensures the reliability of the entire equipment during operation.

[0060] In actual operation, when the device is in use, the forage to be crushed can be placed in the feed hopper 1, and then the forage enters the baffle 2 area along the feed hopper 1. When the forage moves on the baffle 2, the corrugated protrusions 21 on the surface of the baffle 2 can effectively reduce the sliding resistance between the forages, and the arc-shaped flanges 22 on the side edges of the baffle 2 can guide the forages to flow more uniformly to the guide groove 23 at the bottom of the baffle 2, thereby dispersing the forage flow and improving the flow efficiency. After the forage leaves the baffle 2 and enters the range of the crushing cutter head 3, the forage is cut and crushed by the rotating blades. The crushed forage particles fall into the screening mesh 4, and the mesh screens the particle size. The forage particles meeting the specified size requirements pass through the screen holes and enter the discharge box 5 to be discharged, and the particles that do not meet the requirements are retained on the screening mesh 4 for further processing. During the entire operation process, the support 6 supports the overall structure of the device to ensure its stable operation.

[0061] The above is the preferred embodiment of the present application. It should be pointed out that for ordinary skilled persons in the technical field, a number of improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
