Description

Technical Field

[0001] This application relates to the field of forage processing equipment technology, and in particular to a forage rubbing and processing device. Background Technology

[0002] As an important roughage in livestock and poultry farming, forage often needs to be rubbed to improve its palatability, digestibility and storage performance. This process involves partially breaking down, loosening and softening the fiber structure while maintaining its basic length, thereby improving chewability and feeding effect.

[0003] Most existing forage crushing equipment has a simple structure, and its processing method usually only includes one form of crushing or cutting, such as using a single set of hammer-type impact structure or a single set of blade roller-type cutting structure for preliminary treatment. Because forage is often long and tangled in its natural state, has high moisture content, and strong fiber elasticity, a single structure is difficult to achieve sufficient processing of the forage, easily leading to problems such as forage tangling, clogging, incomplete cutting, and poor conveying, which in turn affects subsequent storage, baling, and animal consumption. Furthermore, existing forage crushing equipment is not convenient for conveying processed forage, hindering continuous operation. Therefore, it is necessary to further improve existing forage crushing equipment and design a compact processing device suitable for efficient forage crushing. Utility Model Content

[0004] This application provides a forage rubbing and processing device to solve the problem that existing forage rubbing equipment using a single processing method is difficult to achieve sufficient processing of forage.

[0005] This application provides a forage rubbing and processing device, including a frame, a processing box, a rubbing assembly, a discharge conveying assembly, and a drive device; The frame is equipped with a processing box for kneading the input forage and a discharge conveying assembly installed behind the processing box to convey the forage after kneading. The kneading assembly is located inside the processing box and includes a hammer-type kneading assembly, a rotary blade kneading assembly, and a forage guiding and pressing assembly for sequentially processing the forage. The top of the processing box is equipped with a forage feeding hopper above the hammer-type kneading assembly. The hammer-type kneading assembly, the rotary blade kneading assembly, and the forage guiding and pressing assembly are driven by a drive device.

[0006] In one optional embodiment, the hammer-type kneading assembly includes a main shaft with three rotating wheels spaced apart on it. The three rotating wheels are fixedly connected to each other by four connecting rods. Each connecting rod has multiple evenly spaced hammer blades suspended from it. One end of each hammer blade has a through hole for hanging on the connecting rod. Each connecting rod has multiple sets of spacer assemblies arranged corresponding to the hammer blades. Each hammer blade is located between a set of spacer assemblies to restrict its movement on the shaft of the connecting rod. The hammer blades can swing around the connecting rod to perform hammer-type kneading treatment on the forage. The two ends of the main shaft are mounted on the side wall of the processing box through bearings and can be driven to rotate by a drive device.

[0007] In one optional embodiment, the rotary blade kneading assembly includes a blade shaft with two spaced-apart blade disc supports. Four blades in the form of long plates are detachably connected to the two blade disc supports. The four sets of blades are evenly arranged circumferentially around the blade shaft and form multiple cutting surfaces. The two ends of the blade shaft are mounted on the side wall of the processing box through bearings and can be driven to rotate by a drive device.

[0008] In one optional embodiment, the grass-guiding and pressing assembly includes a grass-scraping plate and an opposing pressure roller assembly. The grass-scraping plate is disposed on the discharge direction side of the rotary blade kneading assembly and connected to a rotating shaft rotatably connected between the side walls of the processing box. The opposing pressure roller assembly is rotatably installed inside the processing box and positioned between the grass-scraping plate and the discharge conveying assembly. The grass-scraping plate has a plate-like structure and can guide the grass into the opposing pressure roller assembly under the rotation of the rotating shaft. The opposing pressure roller assembly includes an upper pressure roller and a lower pressure roller. The upper and lower pressure rollers can rotate in opposite directions and form a pressing gap between them for squeezing the grass. The upper pressure roller is an octagonal roller with eight sets of toothed surfaces on its roller surface. One end of the roller shaft of the upper pressure roller is meshed with one end of the rotating shaft through a gear set. The lower pressure roller is a smooth circular roller. One end of the roller shaft of the lower pressure roller is connected to one end of the rotating shaft through a sprocket transmission mechanism.

[0009] In one optional embodiment, the discharge conveying assembly is used to receive and convey the forage conveyed by the forage guiding and pressing assembly, and the discharge conveying assembly is a chain plate conveying structure.

[0010] In one optional embodiment, the discharge conveying assembly includes chains and sprockets respectively arranged on the left and right sides. The chains are wound around the front and rear sets of sprockets. Multiple conveying plates are installed at equal intervals along the chain links. The conveying plates move synchronously with the chains under the drive of the chains to carry and convey the kneaded grass. One end of the drive shaft of the sprocket is driven by a drive device to realize synchronous transmission in the discharge process.

[0011] In one optional embodiment, the driving device includes a motor fixedly mounted on the frame. The output shaft of the motor is connected to one end of the blade shaft of the rotary blade kneading assembly via a belt drive mechanism. The hammer-type kneading assembly and the rotary blade kneading assembly are connected by a belt drive to achieve synchronous transmission. The other end of the blade shaft is connected to the grass-guiding and pressing assembly via a gear drive mechanism.

[0012] In one alternative embodiment, the bottom end of the frame is provided with rollers.

[0013] In one alternative embodiment, an inspection cover is hinged to one side of the processing box.

[0014] In one optional embodiment, a protective baffle is provided around the discharge conveying assembly, and a protective top cover is also provided on the side of the protective baffle near the guide grass pressing assembly.

[0015] Compared with the prior art, this application has the following beneficial effects: 1. This application provides a forage kneading and processing device. Inside the processing chamber, a hammer-type kneading component, a rotary blade kneading component, and a grass-guiding and pressing component are sequentially arranged, forming a progressively advanced multi-stage kneading system. After the forage is fed into the hopper, it is processed sequentially through these components, following a process of "hammering loosening—blade cutting—pressing roller shaping." Unlike traditional equipment that relies solely on a single set of hammers or blade rollers for kneading, this structure achieves deeper and more uniform kneading and localized breaking down, resulting in more thorough processing and improved feed performance and subsequent storage quality. This graded, combined processing method helps to gradually break down, shear, and shape the forage fiber structure, thereby improving the thoroughness of kneading. Especially for wet forage with strong fiber toughness and high entanglement, this application can effectively reduce processing residue and increase processing depth, creating a good foundation for subsequent use.

[0016] 2. This application integrates the hammer-type kneading component, the rotary blade kneading component, and the forage guiding and pressing component into the same processing box, arranged sequentially inside the box according to the processing order. This significantly improves the situation where poor connection between components easily leads to transmission blockages or even forage clogging. After the forage falls into the feed hopper, it first enters the hammer-type kneading component for loosening, then is sheared by the rotary blade kneading component, and finally guided to the forage guiding and pressing component for shaping. This structural distribution enables continuous processing of forage, resulting in smoother operation, higher overall processing continuity, and reduced possibility of accumulation and blockage. Although the hammer-type kneading component, the rotary blade kneading component, and the forage guiding and pressing component in this application are structurally unified within the processing box, their functions are clearly defined and they cooperate with each other. The hammer-type kneading assembly is responsible for striking and loosening coarse fibers, laying the foundation for subsequent cutting. The rotary blade kneading assembly uses multiple sets of blades to further shear and refine the fibers. The grass-guiding and pressing assembly is located at the front of the discharge channel, serving both as a grass guide and a pressing function, thus controlling the discharge at the end of the processing. This layout logic, which divides the work according to the process, helps to prevent grass from getting stuck in a single section during processing due to unbroken or excessively tangled fibers, thereby reducing the blockage rate during continuous operation and improving the smoothness of equipment processing.

[0017] 3. This application includes a discharge conveyor assembly installed behind the processing box to transport the processed forage, which is mounted as a whole on the frame, forming a complete structural chain from processing to output. This embodiment's application of this integrated approach to forage processing and conveying avoids disconnection between processing and output, providing a more stable and continuous forage output channel for subsequent processes such as baling, drying, or storage and transportation. This improves operational efficiency and enhances the equipment's ability to adapt to continuous operation scenarios. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0022] Please see Figures 1-7 This application provides a forage rubbing and processing device, including a frame 500, a processing box 600, a rubbing component, a discharge conveying component 400, and a drive device 700.

[0023] The frame 500 is equipped with a processing box 600 for kneading the input forage and a discharge conveying assembly 400 installed behind the processing box 600 to convey the forage after kneading. The kneading assembly is located inside the processing box 600 and includes a hammer-type kneading assembly 100, a rotary blade kneading assembly 200, and a grass-guiding and pressing assembly 300 for sequentially processing the forage. The top of the processing box 600 is equipped with a grass inlet hopper 610 above the hammer-type kneading assembly 100. The hammer-type kneading assembly 100, the rotary blade kneading assembly 200, and the grass-guiding and pressing assembly 300 are driven by a drive device 700.

[0024] To address the limitations of existing forage rubbing equipment in terms of structure and processing methods, this embodiment sequentially incorporates a hammer-type rubbing component 100, a rotary blade rubbing component 200, and a grass-guiding and pressing component 300 within the processing chamber 600, forming a progressively advanced multi-stage rubbing system. After the forage is fed into the feed hopper 610, it is processed sequentially through the hammer-type rubbing component 100, the rotary blade rubbing component 200, and the grass-guiding and pressing component 300, following a process of "hammering loosening—blade cutting—pressing roller shaping." Unlike traditional equipment that relies solely on a single set of hammers or blade rollers for rubbing, this structure enables deeper and more uniform rubbing and localized breaking, resulting in more thorough processing and improved feed performance and subsequent storage quality. This graded and combined processing method in this embodiment helps to gradually break down, shear, and shape the fiber structure of the forage, thereby improving the thoroughness of kneading. Especially for wet forage with strong fiber toughness and high entanglement, this embodiment can effectively reduce processing residue, increase the depth of processing, and create a good foundation for subsequent use.

[0025] In this embodiment, the hammer-type kneading component 100, the rotary blade kneading component 200, and the grass-guiding and pressing component 300 are integrated and arranged in the same processing box 600, and are sequentially arranged inside the processing box 600 according to the processing sequence. This significantly improves the situation where poor connection between components easily leads to transmission blockage or even grass jamming. After the grass falls into the feed hopper 610, it first enters the hammer-type kneading component 100 for loosening, then is sheared by the rotary blade kneading component 200, and then is guided to the grass-guiding and pressing component 300 for shaping. Through this structural distribution, continuous processing of forage is achieved, the operation is smoother, and the overall processing continuity is higher, reducing the possibility of accumulation and blockage during the process. In this embodiment, although the hammer-type kneading component 100, the rotary blade kneading component 200, and the grass-guiding and pressing component 300 are uniformly installed in the processing box 600, their functions are clearly defined and they cooperate with each other. The hammer-type kneading assembly 100 is responsible for striking and loosening coarse fibers, laying the foundation for subsequent cutting. The rotary blade kneading assembly 200 uses multiple sets of blades to further shear and improve the fineness of the fibers. The grass-guiding and pressing assembly 300 is located at the front end of the discharge channel, serving both as a grass guide and a pressing function, thus controlling the discharge at the end of the processing. This layout logic, which divides the work according to the process, helps to prevent grass from getting stuck in a single section during processing due to unbroken or excessively tangled fibers, thereby reducing the blockage rate during continuous operation and improving the smoothness of equipment processing.

[0026] To address the issues of poor feed transfer and operational interruptions in traditional equipment after forage kneading, this embodiment incorporates a discharge conveyor assembly 400 behind the processing box 600, which is mounted on the frame 500, forming a complete structural chain from processing to output. This integrated approach to forage processing and conveying avoids disconnections between processing and output, providing a more stable and continuous feed output channel for subsequent processes such as baling, drying, or storage and transportation. This improves operational efficiency and enhances the equipment's ability to adapt to continuous operation scenarios.

[0027] In some embodiments, the hammer-type kneading assembly 100 includes a main shaft 101, on which three rotating wheels 102 are spaced apart. The three rotating wheels 102 are also fixedly connected to each other by four connecting rods 103. Each connecting rod 103 is provided with a plurality of evenly spaced hammers 104. One end of each hammer 104 is provided with a through hole for hanging on the connecting rod 103. Each connecting rod 103 is provided with a plurality of sets of spacer assemblies 105 corresponding to the hammers 104. Each hammer 104 is located between a set of spacer assemblies 105 to restrict its movement on the shaft of the connecting rod 103. The hammers 104 can swing around the connecting rod 103 to perform hammer-type kneading treatment on the forage. The two ends of the main shaft 101 are mounted on the side wall of the processing box 600 by bearings and can be driven to rotate by the drive device 700.

[0028] In this embodiment, the hammer-type kneading assembly 100 has three sets of rotating wheels 102 connected by a main shaft 101, and four connecting rods 103 are connected between each set of rotating wheels 102. Multiple hammer blades 104 are evenly suspended on each connecting rod 103, arranged in a uniform distribution. Driven by rotation, the main shaft 101 drives the hammer blades 104 to perform multi-point, high-frequency oscillating hammering, ensuring that the forage is struck from multiple angles and directions upon entering. Compared to the traditional single-row hammer blade structure, this multi-layered hammering layout is more adaptable to wet forage and long-fiber forage, effectively promoting untangling and initial loosening of the forage, thereby enhancing the initial kneading treatment effect.

[0029] Each hammer blade 104 is suspended from the connecting rod 103 via a perforation, and is clamped and limited on both sides by spacer assemblies 105. This limiting structure inhibits axial sliding of the hammer blade 104 during high-speed rotation and stabilizes the relative position of the hammer blade 104 in space. In practical applications, hammer blades 104 on different connecting rods 103 should be staggered during arrangement to avoid them from interlocking if they are too long. In this embodiment, the hammer blade 104 is suspended from the connecting rod 103 in a swinging manner, forming a swinging impact state during rotation. This retains the impact force and improves the ability to adapt to changes in the shape of the forage, effectively alleviating entanglement and jamming problems when processing high-moisture, long-fiber forage. The two ends of the main shaft 101 are mounted on the side wall of the processing box 600 via bearings, which support the entire hammer-type kneading assembly 100 and enhance the stability of the operation.

[0030] In some embodiments, the rotary blade kneading assembly 200 includes a blade shaft 201, on which two spaced-apart blade disc supports 202 are provided. Four blades 203 in the form of long plates are detachably connected to the two blade disc supports 202. The four sets of blades 203 are evenly arranged circumferentially around the blade shaft 201 and form multiple cutting surfaces. The two ends of the blade shaft 201 are mounted on the side wall of the processing box 600 through bearings and can be driven to rotate by the drive device 700.

[0031] In the above embodiment, the rotary blade kneading assembly 200 drives two sets of blade disc supports 202 to rotate via the blade shaft 201. Four long, plate-shaped blades 203 are detachably connected to the two blade disc supports 202. After the forage is initially broken up by the front-end hammer-type kneading assembly, it can be gradually fed into the area of ​​the rotary blade kneading assembly 200 during rotation, thus receiving multi-directional, staggered cutting. This further breaks down the forage stem structure and refines the fiber bundles, contributing to a deeper kneading depth. The symmetrical arrangement of the blades 203 helps reduce the eccentric force during overall rotation, improving the stability of the blade shaft 201. The blade shaft 201 is supported at both ends by bearings on the processing box structure, which plays a positive role in reducing vibration and noise during operation, while also helping to delay component wear and extend service life. Furthermore, the blades 203 have a detachable structure, installed via bolts or clips, allowing users to easily replace or clean the blades as needed, improving the flexibility of later maintenance. Compared to traditional cutting devices that use a single set of blades, this structure provides more cutting surfaces while maintaining a compact layout, which helps to improve the uniformity of forage fiber processing.

[0032] In some embodiments, the grass-guiding and pressing assembly 300 includes a grass-scraping blade 310 and a counter-pressure roller assembly 320. The grass-scraping blade 310 is disposed on the discharge direction side of the rotary blade kneading assembly 200 and connected to a rotating shaft 311 rotatably connected between a set of side walls of the processing box 600. The counter-pressure roller assembly 320 is rotatably installed inside the processing box 600 and is located between the grass-scraping blade 310 and the discharge conveying assembly 400. The grass-scraping blade 310 has a plate-like structure and can guide grass into the counter-pressure roller assembly under the rotation of the rotating shaft 311. Component 320; The opposing pressure roller assembly 320 includes an upper pressure roller 321 and a lower pressure roller 322. The upper pressure roller 321 and the lower pressure roller 322 can rotate in opposite directions and form a pressing gap between them for squeezing the forage. The upper pressure roller 321 is an octagonal roller with eight sets of teeth arranged on its roller surface. One end of the roller shaft of the upper pressure roller 321 is connected to one end of the rotating shaft 311 through a gear set. The lower pressure roller 322 is a smooth circular roller. One end of the roller shaft of the lower pressure roller 322 is connected to one end of the rotating shaft 311 through a sprocket transmission mechanism.

[0033] In the above embodiments, the forage guiding and pressing assembly 300, through the coordinated cooperation of the scraper 310 and the opposing pressure roller assembly 320, realizes the guidance and pressing of forage from the rotary blade kneading assembly 200 to the discharge conveying assembly 400. The scraper 310 has a plate-like structure and can rotate with the movement of the rotating shaft 311. When the forage arrives at this area from the upstream process, the scraper can guide the dispersed forage to the subsequent opposing pressure roller assembly 320, facilitating centralized diversion, reducing stagnation and accumulation in the processing box, and reducing operational interference caused by blockage. The opposing pressure roller assembly 320 is located downstream of the scraper and includes an upper pressure roller 321 and a lower pressure roller 322. A certain pressing gap is maintained between the two to moderately compact the forage, improving its overly loose state and thus enhancing the overall conveyability of the forage. The upper pressure roller 321 has an octagonal roller structure with eight sets of teeth evenly distributed on its surface, which helps to enhance the gripping and guiding of the forage and to moderately break the surface fibers during the pressing process. The lower pressure roller 322 has a smooth circular roller structure, which works with the upper pressure roller 321 to guide and press the forage, thereby improving the stability during the compaction process. One end of the roller shaft of the upper pressure roller 321 is connected to one end of the rotating shaft 311 through a gear set, and one end of the roller shaft of the lower pressure roller 322 is connected to one end of the rotating shaft 311 through a sprocket transmission mechanism, forming a coordinated rotation drive mode, and the transmission process is smooth and reliable. This structural layout of the forage guiding and pressing component 300 in this embodiment, which combines scraping and pressing, not only helps to improve the smoothness of the forage during the guiding process, but also improves the uniformity of the forming during the compaction stage, laying a stable foundation for subsequent conveying and packaging, and further improving the overall processing efficiency and smoothness of the equipment.

[0034] In some embodiments, the discharge conveying assembly 400 is used to receive and convey the grass conveyed by the grass guiding and pressing assembly 300, and the discharge conveying assembly 400 is a chain plate type conveying structure.

[0035] In this embodiment, the discharge conveying assembly 400 adopts a chain plate conveying structure. Compared with common belt conveyors or screw conveyors, it has a stronger adaptability to conveying relatively loose, high-moisture, and irregularly shaped crumbs. The chain plate structure has high rigidity and load-bearing capacity, which can effectively reduce the probability of slippage, accumulation, or jamming when dealing with wet, heavy, or lumpy forage, thereby improving the stability of the conveying process.

[0036] In some embodiments, the discharge conveying assembly 400 includes a chain 401 and a sprocket 402 respectively arranged on the left and right sides. The chain 401 is wound around the front and rear sets of sprockets 402. Multiple conveying plates 403 are equidistantly installed on the chain 401 along the chain links. The conveying plates 403 move synchronously with the chain 401 under the drive of the chain 401, and are used to carry and convey the kneaded grass. One end of the drive shaft of the sprocket 402 is driven by the drive device 700 to realize synchronous transmission in the discharge process.

[0037] In the structural design of the discharge conveying assembly 400, this embodiment adopts a chain-plate structure with chains 401 and sprockets 402 arranged on both sides, and multiple conveying plates 403 are equidistantly arranged on the chains 401. Compared with a single-sided chain drive system, this configuration has significant advantages in terms of structural stability and operational synchronization. The chains 401 on both sides jointly drive the conveying plates 403, enabling them to maintain a relatively horizontal running posture during the conveying process, which helps to improve the stable support capacity of the forage on the conveying plates. The chains 401 are arranged in a closed path between the front and rear sets of sprockets 402, causing the conveying plates 403 to reciprocate along a circular trajectory, forming a continuous flow of forage conveyed from the processing box 600 to the outside.

[0038] During operation, after the drive unit 700 is activated, the chain 401 begins to run, and multiple conveyor plates 403 move synchronously along the chain's running path. The forage is continuously supported on these plates, which helps maintain a flat conveying state and reduces deviation or overturning caused by localized gravity concentration. Since the discharge conveyor assembly 400 is located immediately behind the processing box 600 and close to the forage pressing assembly 300, the forage can naturally transition to the conveying section immediately after pressing and shaping, reducing idle time between workstations and improving the overall processing flow's continuity and response speed. Furthermore, this conveying method has excellent directional control capabilities, facilitating the output of forage along a predetermined direction and enabling continuous linkage with downstream processing steps such as packaging and bundling. This enhances the device's process compatibility within centralized forage processing lines.

[0039] In some embodiments, the drive device 700 includes a motor 701 fixedly mounted on the frame 500. The output shaft of the motor 701 is connected to one end of the blade shaft 201 of the rotary blade kneading assembly 200 via a belt drive mechanism. The hammer-type kneading assembly 100 and the rotary blade kneading assembly 200 are connected by a belt drive to achieve synchronous transmission. The other end of the blade shaft 201 is connected to the grass-guiding and pressing assembly 300 via a gear drive mechanism.

[0040] In this embodiment, motor 701, as the sole power source of the device, is fixedly mounted on frame 500. Its output shaft is first connected to one end of the blade shaft 201 of the rotating blade kneading assembly 200 via a belt drive mechanism, providing the blade shaft 201 with the main force input. Based on this, the hammer-type kneading assembly 100 achieves synchronous linkage with the blade shaft 201 via a belt, avoiding speed differences caused by multiple motor drives, helping to reduce energy consumption, and improving the consistency of operation of each component.

[0041] Furthermore, the other end of the cutter shaft 201 is connected to the guide and pressing assembly 300 via a gear mechanism, forming a power sequence chain from the motor 701 to each component of the kneading assembly. The three functional sections—hammering, cutting, and pressing—are all driven by the motor 701 in this transmission structure. The overall configuration is compact, reducing the number of motors, thus simplifying the electrical control system structure, reducing the overall machine size, and making subsequent assembly and maintenance operations more convenient.

[0042] It should be noted that the motor 701, as the power source of the entire machine, in this embodiment drives the hammer-type kneading component 100, the rotary blade kneading component 200, and the grass-guiding and pressing component 300 in sequence through a combination of belt drive and gear drive, thereby completing the multi-stage kneading process of the forage. However, those skilled in the art should understand that the transmission connection method between the above components is not limited to this. Chain drive, synchronous belt drive, universal coupling drive, gearbox linkage, and other mechanical transmission forms can also be used according to actual usage requirements to achieve the corresponding power output and structural coordination effects. Those skilled in the art can select a transmission structure suitable for specific working conditions to achieve the coordinated operation of each component based on the description in the specification.

[0043] In some embodiments, the bottom end of the frame 500 is provided with rollers 501.

[0044] In this embodiment, by installing rollers 501 at the bottom of the frame 500, the forage rubbing and processing device has a certain degree of mobility, which facilitates position adjustment according to operational needs. Optionally, the rollers 501 are universal wheels and equipped with a flip-locking mechanism to switch between the moving and fixed states of the device, thereby better suited to forage processing scenarios that require multi-point operation or high operation frequency.

[0045] In some embodiments, a maintenance cover 502 is hinged to one side of the processing box 600.

[0046] An inspection cover 502 is provided on one side of the processing box 600 and is connected to the side wall of the processing box 600 by a hinge, which makes the equipment more convenient to operate during daily maintenance and troubleshooting. The hammer-type kneading component 100 is an area that is prone to jamming or entanglement of straw. By providing the inspection cover 502, it is convenient to conduct regular inspections and necessary maintenance operations.

[0047] Furthermore, the inspection cover 502 is hinged to the processing box 600, allowing operators to directly lift the inspection cover 502 to observe and process the interior of the processing box 600, which helps reduce maintenance time.

[0048] In some embodiments, a protective baffle 404 is provided around the discharge conveying assembly 400, and a protective top cover 405 is also provided on the side of the protective baffle 404 near the guide grass pressing assembly 300.

[0049] In the above embodiments, a protective baffle 404 is added to the periphery of the discharge conveying component 400, and a protective top cover 405 is set on the side near the grass guiding and pressing component 300. This is beneficial to enhance the protective performance and structural sealing of the equipment during operation, and can reduce the splashing or scattering of grass during the conveying process, reduce environmental pollution caused by grass spillage, and reduce the interference of grass to operators and surrounding facilities.

[0050] The following describes the usage process of the forage rubbing and processing device of this application, based on its structure and working principle: During operation, the operator first moves the entire device to the designated work position and starts the drive unit 700, which drives the hammer-type kneading component 100, the rotary blade kneading component 200, and the grass-guiding and pressing component 300 in the processing box 600 into a pre-operation state. Then, the forage to be processed is evenly fed into the grass hopper 610. The forage falls into the hammer-type kneading component 100 by gravity, where the high-speed swinging hammer blades 104 initially loosen and untangle the forage, breaking up large pieces and providing basic treatment for subsequent processing stages.

[0051] After being hammered, the hay is drawn into the blade 203 area of ​​the rotating blade kneading assembly 200 during rotation. Multiple blades rotate at high speed around the blade shaft 201, cutting the hay from multiple directions to further refine the fibers, separate the stems and leaves, and improve its physical structure. The sheared hay then enters the guide and pressing assembly 300, where it is conveyed between the upper and lower pressure rollers 321 and 322 under the guidance of the scraper 310. Through the pressing action formed by the opposing rotation, the hay is shaped and pressed, making its density and shape more suitable for conveying and processing.

[0052] Finally, the compressed forage transitions naturally from the end of the forage compression assembly 300 to the discharge conveyor assembly 400. Multiple conveyor plates 403 move synchronously and smoothly under the drive of the chain 401, stably outputting the forage for subsequent baling, storage, or transportation. Throughout the entire operation, the components cooperate sequentially, the power transmission is smooth, and the equipment can operate continuously for extended periods, making it suitable for forage processing tasks in pastures or feed processing plants of different sizes.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
