Description

Technical Field

[0001] This invention relates to the field of feeding device technology, specifically an anti-stacking type total mixed feed spreader. Background Technology

[0002] Total Mixed Feed (TMR) spreaders are core equipment in modern intensive livestock farming. They are mainly used to mix roughage, concentrates, and additives in a specific ratio and then feed them evenly to livestock, which is crucial for improving feeding efficiency and ensuring balanced nutrition. With the rapid development of large-scale farming, the demand for continuous and stable operation of spreaders is constantly increasing. However, existing horizontal self-propelled spreaders generally suffer from feed accumulation problems in actual use, which seriously restricts operational efficiency.

[0003] Currently, traditional feed spreaders often experience feed bridging and arching above the discharge port when conveying total mixed feed. This causes the discharge auger to spin idly below, preventing the feed from falling smoothly and requiring frequent manual cleaning, which disrupts feeding continuity and increases labor intensity. Simultaneously, long-fiber feed easily entangles on the auger, gradually forming dense fibrous clumps. This not only reduces conveying efficiency but can also cause excessive load on the auger due to fiber clump jamming, leading to motor overload or even equipment damage. To address these issues, this invention designs an anti-accumulation total mixed feed spreader, overcoming the technical pain points of feed accumulation and entanglement. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-stacking fully mixed feed spreader to solve the problems of feed accumulation and entanglement in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The material spreading vehicle includes a carriage, an output module, and a conveying module. The conveying module includes an upper spiral conveyor rod, a sliding rod, and a cross threaded column. The upper spiral conveyor is hollow, and each section of the upper spiral conveyor is provided with a through hole. One end of the sliding rod is inserted into the upper spiral conveyor. On the cylindrical surface of the sliding rod near the discharge end of the spreading vehicle, there are staggered stirring rods. On the cylindrical surface of the remaining part of the sliding rod, there are cutting blades. Both the stirring rods and the cutting blades pass through the through holes of the upper spiral conveyor. The stirring rods and the upper spiral conveyor are slidably connected. One end of the cross-threaded post is fixedly connected to the carriage, and the cross-threaded post has cross-threaded grooves on its surface; One end of the sliding rod near the discharge end of the spreading vehicle is sleeved on the cross-threaded column. A traveling wheel is provided on the inner wall of the end of the sliding rod sleeved on the cross-threaded column. The traveling wheel is placed in the cross-threaded groove, and the traveling wheel and the inner wall of the sliding rod are rotatably connected.

[0006] When the feed truck is working, the feed is loaded into the area of ​​the conveying module inside the truck body. The conveying module transfers the feed to the output module, which then outputs the feed. When the conveying module is working, the upper spiral conveyor rod inside it rotates. As the upper spiral conveyor rod rotates, the feed moves towards the discharge end under the push of the spiral blades. Simultaneously, the upper spiral conveyor rod drives the sliding rod to rotate synchronously. As the traveling wheel engages in the cross-thread groove of the cross-threaded column, the sliding rod reciprocates linearly along the trajectory of the cross-thread groove. The cutting blade and stirring rod on the sliding rod reciprocate synchronously within the through hole. When long-fiber feed is wrapped around the conveying section of the upper spiral conveyor rod, the cutting blade moves back and forth with the sliding rod, cutting the wrapped long-fiber feed into short segments to prevent overload of the power source and ensure feed conveying efficiency. When the feed arches or bridges above the feeding section of the upper spiral conveyor rod, the stirring rod, driven by the sliding rod, reciprocates and rotates to stir the feed, keeping it loose and uniform during conveying, preventing it from clumping due to accumulation, and ensuring that the feed falls smoothly.

[0007] Furthermore, the carriage is divided into a drive area, a conveying area, and an output area, with the conveying area located between the drive area and the output area; The conveying area is wider at the top and narrower at the bottom, with the bottom of the conveying area being arc-shaped. One end of the arc-shaped bottom of the conveying area is connected to the output area.

[0008] The truck body is divided into three areas: a drive zone, a feeding zone, and an output zone. These three zones are responsible for different functional modules, each performing its own function while cooperating with each other, effectively improving the overall working efficiency of the feed truck. The feeding zone features a design that is wider at the top and narrower at the bottom. Feed, after being fed from the top of the truck body, naturally slides down the sloping inner wall to the upper spiral conveyor for transport and mixing. The rounded bottom design matches the shape of the lower spiral conveyor, preventing excessive feed residue at the bottom of the feeding zone and reducing feed waste.

[0009] Furthermore, the conveying module also includes a lower spiral conveyor and a reverse spiral conveyor. The lower spiral conveyor is located below the upper spiral conveyor and is rotatably connected to the carriage. The reverse spiral conveyor is rotatably connected to the carriage and is located between the lower spiral conveyor and the upper spiral conveyor. The central axes of the lower spiral conveyor, the reverse spiral conveyor, and the upper spiral conveyor are parallel. The central axis of the lower spiral conveyor and the central axis of the arc-shaped bottom end of the conveying area are on the same vertical plane.

[0010] The spiral blades of the lower spiral conveyor rotate in the same direction as the upper spiral conveyor. When feed falls from the arc-shaped bottom of the conveying zone, the lower spiral conveyor pushes the feed deposited at the bottom towards the output zone, preventing the feed from accumulating at the bottom of the conveying zone for a long time, which could lead to spoilage or clumping. The spiral blades of the reverse spiral conveyor rotate in the opposite direction to the upper and lower spiral conveyors. When it rotates, it generates a reverse thrust on the feed that passes through, causing the feed to stagnate and tumble briefly during the conveying process, further breaking up any small clumps of feed and making different batches of feed mix more evenly. In addition, under the action of the reverse spiral conveyor, the portion of feed accumulated at the bottom of the conveying zone near the entrance of the output zone will flow back towards the lower spiral conveyor, preventing blockage at the entrance of the output zone due to excessive instantaneous accumulation of feed.

[0011] Furthermore, the transmission module also includes a drive unit, which is located in the drive area and includes a drive motor, transmission gears, and a transmission belt. There are multiple transmission gears, which are fixedly connected to the ends of the upper spiral conveyor rod, the lower spiral conveyor rod, and the reverse spiral conveyor rod near the drive area. The drive motor is fixedly installed in the drive area, and the output end of the drive motor is also fixedly equipped with a transmission gear. All transmission gears are connected by a transmission belt, and all transmission gears rotate in the same direction.

[0012] After the drive motor starts, the transmission gear at its output end synchronously drives the transmission gears connected to the upper spiral conveyor rod, lower spiral conveyor rod, and reverse spiral conveyor rod to rotate via the transmission toothed belt. This ensures that the three conveyor rods maintain the same direction of rotation, creating a continuous conveying path for the feed within the conveying zone. Simultaneously, the drive unit is installed entirely within a separate drive area, physically separated from the conveying and output areas. This effectively prevents feed powder or moisture from entering the drive components, reducing the risk of gear corrosion and toothed belt slippage, and extending the service life of the drive system.

[0013] Furthermore, the output module includes a conveyor motor, conveyor rollers, and a conveyor belt. Conveyor rollers are provided at both ends of the output area. The central axis of the conveyor rollers is parallel to the central axis of the lower spiral conveyor rod. The two ends of the conveyor rollers are rotatably connected to the inner wall of the output area. The conveyor motor is fixedly connected to the outer wall of the output area. The output end of the conveyor motor is fixedly connected to one end of the conveyor rollers. The two ends of the conveyor belt are sleeved on the conveyor rollers at both ends of the output area. The two ends of the conveyor belt are located on both sides of the lower spiral conveyor rod.

[0014] When the conveyor module delivers feed to the output area, the feed falls into the middle section of the conveyor belt. After the conveyor motor starts, it drives the connected conveyor rollers to rotate, which in turn drives the conveyor belt, transporting the feed on it. By changing the output direction of the conveyor motor, the operating direction of the conveyor belt can be flexibly adjusted, allowing the feed to be switched to be discharged to both sides of the feed spreader.

[0015] Furthermore, the output module also includes a material spreading plate, with an equidistant gap between the bottom surface of the material spreading plate and the conveyor belt.

[0016] The equidistant gap between the feed spreading plate and the upper surface of the conveyor belt can be adjusted according to the actual output requirements. The equidistant gap between the feed spreading plate and the upper surface of the conveyor belt can organize the feed output from the conveyor belt into a uniform thickness layer, avoiding the situation of excessive or insufficient feed in some areas when spreading due to uneven accumulation height on the conveyor belt. This ensures the uniformity of spreading and reduces feed waste.

[0017] Furthermore, one end of the spreading plate is fixedly connected to the partition between the output area and the conveying area, and the other end of the spreading plate is fixedly connected to the end of the output area away from the conveying area. The closer one end of the spreading plate is to the conveying area, the shorter the distance between one end of the spreading plate and the central axis of the lower spiral conveyor rod.

[0018] When feed falls from the conveyor module into the end of the conveyor belt near the feeding zone, the spreading plate at that end initially intercepts and guides the feed, preventing it from being directly output by the conveyor belt immediately upon landing. As the conveyor belt rotates, the inclined structure helps to spread the feed more evenly across the width of the conveyor belt, improving the uniformity of subsequent spreading. Furthermore, this inclined design, compared to a design parallel to the central axis of the lower spiral conveyor, reduces hard collisions between the feed and the spreading plate, improving feed conveying efficiency.

[0019] Furthermore, the upper spiral conveyor rod, sliding rod, and cross threaded column are all located within the conveying zone. The central axis of the upper spiral conveyor rod is parallel to the central axis of the bottom of the arc segment of the conveying zone. The upper spiral conveyor rod, sliding rod, and cross threaded column are arranged in two sets with axial symmetry about the conveying zone, and the central axes of the upper spiral conveyor rod, sliding rod, and cross threaded column in each set coincide.

[0020] Two sets of symmetrical upper spiral conveyor rods, sliding rods, and cross-threaded columns work synchronously to simultaneously convey, cut, and mix feed on both sides of the conveying zone, significantly improving feed processing efficiency and avoiding uneven feed accumulation caused by unilateral conveying. When feed is fed from the top of the truck, the upper spiral conveyor rods on both sides rotate synchronously, pushing the feed towards the discharge end. Simultaneously, the sliding rods on both sides reciprocate linearly under the action of the cross-threaded columns, with cutting blades on their surfaces simultaneously cutting the tangled long-fiber feed, while the mixing rods simultaneously mix the arched feed, ensuring uniform processing of feed throughout the entire conveying zone.

[0021] Furthermore, multiple reverse spiral conveyor rods are symmetrically arranged about the axisymmetric plane of the material conveying zone.

[0022] Multiple reverse spiral conveyor rods are evenly distributed in the conveying area. This symmetrical and equidistant layout allows the feed piled up on both sides of the lower spiral conveyor rod and the upper spiral conveyor rod near the entrance of the output area to be conveyed in reverse at the same time. This effectively avoids excessive feed accumulation on one side, ensures the uniformity of feed distribution at the bottom of the conveying area, and prevents the conveying module from being worn or stuck due to excessive pressure on one side. This further ensures the stable operation of the spreading vehicle.

[0023] Furthermore, both ends of the cutting blade along the conveying direction of the upper spiral conveyor rod are cutting edges.

[0024] The design of the cutting blade's two end faces allows it to effectively cut long-fiber feed wrapped around the upper spiral conveyor section, regardless of whether the sliding rod moves towards or away from the discharge end, as it rotates with the upper spiral conveyor and reciprocates along the intersecting thread grooves. This significantly improves the processing efficiency of long-fiber feed and avoids conveying jams caused by fiber entanglement. Simultaneously, the two end-face design reduces uneven wear caused by long-term stress on a single cutting edge, extending its service life and reducing maintenance frequency.

[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves automatic cutting of long-fiber feed and reciprocating mixing of arched feed by setting a combination structure of upper spiral conveying rod, sliding rod and cross threaded column in the conveying module of the feed spreader, effectively solving the problems of feed entanglement and accumulation in traditional feed spreaders; 2. The feed spreading plate of the present invention can intercept and guide the feed on the conveyor belt, so that the feed is more evenly spread across the width of the conveyor belt, preventing excessive or insufficient local spreading during the spreading process, thus ensuring the uniformity of spreading and reducing feed waste. 3. This application has multiple reverse spiral conveying rods symmetrically arranged about the axisymmetric surface of the conveying area. These rods can simultaneously convey the feed accumulated on both sides between the lower and upper spiral conveying rods in the opposite direction. This effectively avoids excessive feed accumulation on one side, ensures the uniformity of feed distribution at the bottom of the conveying area, and prevents the conveying module from experiencing uneven wear or jamming due to excessive pressure on one side. This further ensures the stable operation of the spreading vehicle. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example: Figure 1 - Figure 9 As shown, the present invention provides a technical solution: an anti-stacking type fully mixed feed spreader. like Figure 1 , Figures 3 to 6 and Figure 9 As shown, the spreading vehicle includes a carriage 1, an output module 2 and a conveying module 3. The conveying module 3 includes an upper spiral conveying rod 31, a sliding rod 32 and a cross threaded column 33. The upper spiral conveyor rod 31 is hollow, and each section of the upper spiral conveyor rod 31 is provided with a through hole. One end of the sliding rod 32 is inserted into the upper spiral conveyor rod 31. The cylindrical surface of the sliding rod 32 near the discharge end of the spreading vehicle is provided with a staggered stirring rod 34. The cylindrical surface of the remaining part of the sliding rod 32 is provided with a cutting blade 35. Both the stirring rod 34 and the cutting blade 35 pass through the through hole of the upper spiral conveyor rod 31. The stirring rod 34 and the upper spiral conveyor rod 31 are slidably connected. One end of the cross-threaded post 33 is fixedly connected to the carriage 1, and the cross-threaded post 33 has a cross-threaded groove 36 on its cylindrical surface; One end of the sliding rod 32 near the discharge end of the spreading vehicle is sleeved on the cross-threaded column 33. A traveling wheel 37 is provided on the inner wall surface of the end of the sliding rod 32 that is sleeved on the cross-threaded column 33. The traveling wheel 37 is placed in the cross-threaded groove 36, and the traveling wheel 37 and the inner wall surface of the sliding rod 32 are rotatably connected.

[0030] When the feed truck is working, the feed is loaded into the area where the conveying module 3 is located inside the truck body 1. The conveying module 3 conveys the feed to the output module 2, and the output module 2 then outputs the feed. When the conveying module 3 is working, the upper spiral conveying rod 31 inside it rotates. As the upper spiral conveying rod 31 rotates, the feed moves towards the discharge end under the push of the spiral blades. Simultaneously, the upper spiral conveyor rod 31 drives the sliding rod 32 to rotate synchronously. Because the traveling wheel 37 is engaged in the cross-thread groove 36 of the cross-thread column 33, the sliding rod 32 will reciprocate linearly along the trajectory of the cross-thread groove 36. The cutting blade 35 and the stirring rod 34 on the sliding rod 32 reciprocate synchronously in the through hole. When the long fiber feed is wrapped around the conveying section on the upper spiral conveyor rod 31, the cutting blade 35 will move back and forth with the sliding rod 32 to cut the wrapped long fiber feed into short segments, preventing overload of the power source and ensuring the conveying efficiency of the feed. When the feed arches or bridges above the feeding section of the upper spiral conveyor rod 31, the stirring rod 34 will rotate and stir the feed in a reciprocating manner under the drive of the sliding rod 32, so that the feed remains loose and uniform during the conveying process, preventing the feed from clumping due to accumulation and ensuring that the feed can fall smoothly.

[0031] like Figure 2 As shown, the carriage 1 is divided into a drive zone 11, a conveying zone 12 and an output zone 13, with the conveying zone 12 located between the drive zone 11 and the output zone 13; The material conveying area 12 is wider at the top and narrower at the bottom, with the bottom end of the material conveying area 12 being arc-shaped. One end of the arc-shaped bottom end of the material conveying area 12 is connected to the output area 13.

[0032] The truck body 1 is divided into three areas: a drive zone 11, a conveying zone 12, and an output zone 13. These three areas are responsible for different functional modules, each performing its own function while cooperating with each other, effectively improving the overall working efficiency of the feed truck. The conveying zone 12 features a wider top and narrower bottom design. After feed is fed from the top of the truck body 1, it naturally slides down the inclined inner wall to the upper spiral conveyor rod 31 for conveying and mixing. The rounded bottom design matches the shape of the lower spiral conveyor rod 38, preventing excessive feed residue at the bottom of the conveying zone 12 and reducing feed waste.

[0033] like Figure 3 and Figure 4As shown, the conveying module 3 also includes a lower spiral conveyor rod 38 and a reverse spiral conveyor rod 39. The lower spiral conveyor rod 38 is located below the upper spiral conveyor rod 31 and is rotatably connected to the carriage 1. The reverse spiral conveyor rod 39 is rotatably connected to the carriage 1 and is located between the lower spiral conveyor rod 38 and the upper spiral conveyor rod 31. The central axes of the lower spiral conveyor rod 38, the reverse spiral conveyor rod 39 and the upper spiral conveyor rod 31 are parallel. The central axis of the lower spiral conveyor rod 38 and the central axis of the arc-shaped bottom end of the conveying area 12 are on the same vertical plane.

[0034] The spiral blades of the lower spiral conveyor 38 rotate in the same direction as the upper spiral conveyor 31. When feed falls from the arc-shaped bottom of the conveying zone 12, the lower spiral conveyor 38 pushes the feed deposited at the bottom towards the output zone 13, preventing the feed from accumulating at the bottom of the conveying zone 12 for a long time, which could lead to spoilage or clumping. The spiral blades of the reverse spiral conveyor 39 rotate in the opposite direction to the upper spiral conveyor 31 and the lower spiral conveyor 38. When it rotates, it generates a reverse thrust on the feed that passes through, causing the feed to stagnate and tumble briefly during the conveying process, further breaking up any small clumps of feed and making the feed from different batches mix more evenly. In addition, under the action of the reverse spiral conveyor 39, the portion of the accumulated feed at the bottom of the conveying zone 12 near the entrance of the output zone 13 will flow back towards the lower spiral conveyor 38, preventing the entrance of the output zone 13 from being blocked due to excessive accumulation of feed at any moment.

[0035] like Figure 7 As shown, the transmission module 3 also includes a drive unit 310, which is disposed in the drive area 11. The drive unit 310 includes a drive motor 311, a transmission gear 312, and a transmission toothed belt 313. Multiple transmission gears 312 are provided. Each transmission gear 312 is fixedly connected to one end of the upper spiral conveyor rod 31, the lower spiral conveyor rod 38, and the reverse spiral conveyor rod 39 near the drive area 11. The drive motor 311 is fixedly installed in the drive area 11. The output end of the drive motor 311 is also fixedly provided with a transmission gear 312. All transmission gears 312 are connected by a transmission belt 313, and all transmission gears 312 rotate in the same direction.

[0036] After the drive motor 311 starts, the transmission gear 312 at its output end synchronously drives the transmission gear 312 connected to the upper spiral conveying rod 31, the lower spiral conveying rod 38, and the reverse spiral conveying rod 39 to rotate via the transmission belt 313. This ensures that the three conveying rods maintain the same direction of rotation, creating a continuous conveying path for the feed within the conveying zone 12. Simultaneously, the drive unit 310 is installed entirely within a separate drive zone 11, physically separated from the conveying zone 12 and the output zone 13. This effectively prevents feed powder or moisture from entering the drive components, reducing the risk of gear corrosion and belt slippage, and extending the service life of the drive system.

[0037] like Figure 8 As shown, the output module 2 includes a conveyor motor 21, a conveyor roller 22, and a conveyor belt 23. Both ends of the output area 13 are provided with conveyor rollers 22. The central axis of the conveyor roller 22 is parallel to the central axis of the lower spiral conveyor rod 38. Both ends of the conveyor roller 22 are rotatably connected to the inner wall of the output area 13. The conveyor motor 21 is fixedly connected to the outer wall of the output area 13. The output end of the conveyor motor 21 is fixedly connected to one end of the conveyor roller 22. Both ends of the conveyor belt 23 are sleeved on the conveyor rollers 22 at both ends of the output area 13. Both ends of the conveyor belt 23 are located on both sides of the lower spiral conveyor rod 38.

[0038] When the conveying module 3 delivers feed to the output area 13, the feed falls into the middle area of ​​the conveyor belt 23. After the conveyor motor 21 starts, it drives the conveyor roller 22 connected to it to rotate, thereby driving the conveyor belt 23, which transports the feed on it. By changing the output direction of the conveyor motor 21, the running direction of the conveyor belt 23 can be flexibly adjusted, realizing the switching of feed discharge to both sides of the feed spreader.

[0039] like Figure 8 As shown, the output module 2 also includes a material spreading plate 24, and there is an equidistant gap between the bottom end face of the material spreading plate 24 and the conveyor belt 23.

[0040] The equidistant gap between the spreading plate 24 and the upper surface of the conveyor belt 23 can be adjusted according to the actual output requirements. The equidistant gap between the spreading plate 24 and the upper surface of the conveyor belt 23 can organize the feed output from the conveyor belt 23 into a uniform thickness layer, avoiding the situation of excessive or insufficient feed in some areas when spreading due to uneven accumulation height on the conveyor belt 23. This ensures the uniformity of spreading and reduces feed waste.

[0041] like Figure 8 As shown, one end of the spreading plate 24 is fixedly connected to the partition between the output area 13 and the conveying area 12, and the other end of the spreading plate 24 is fixedly connected to the end of the output area 13 away from the conveying area 12. The closer one end of the spreading plate 24 is to the conveying area 12, the shorter the distance between one end of the spreading plate 24 and the central axis of the lower spiral conveyor rod 38.

[0042] When feed falls from the conveyor module 3 into the end of the conveyor belt 23 near the feeding area 12, the spreading plate 24 near the feeding area 12 can initially intercept and guide the feed, preventing it from being directly output by the conveyor belt 23 as soon as it falls. As the conveyor belt 23 rotates, the inclined structure helps to spread the feed more evenly across the width of the conveyor belt 23, improving the uniformity of subsequent spreading. In addition, this inclined design, compared to a design parallel to the central axis of the lower spiral conveyor rod 38, can reduce hard collisions between the feed and the spreading plate 24, improving the feed conveying efficiency.

[0043] like Figure 3 and Figure 4 As shown, the upper spiral conveyor rod 31, the sliding rod 32, and the cross threaded column 33 are all located within the conveying area 12. The central axis of the upper spiral conveyor rod 31 is parallel to the central axis of the bottom of the arc segment of the conveying area 12. The upper spiral conveyor rod 31, the sliding rod 32, and the cross threaded column 33 are arranged in two sets with axial symmetry about the conveying area 12, and the central axes of the upper spiral conveyor rod 31, the sliding rod 32, and the cross threaded column 33 in each set coincide.

[0044] Two sets of symmetrical upper spiral conveyor rods 31, sliding rods 32, and cross-threaded columns 33 work synchronously to simultaneously convey, cut, and mix the feed on both sides of the conveying zone 12, significantly improving feed processing efficiency and avoiding uneven feed accumulation caused by unilateral conveying. When feed is fed from the top of the carriage 1, the upper spiral conveyor rods 31 on both sides rotate synchronously, pushing the feed towards the discharge end; at the same time, the sliding rods 32 on both sides move in reciprocating linear motion synchronously under the action of the cross-threaded columns 33, and the cutting blades 35 on their column surfaces cut the entangled long fiber feed synchronously, while the mixing rods 34 mix the arched feed synchronously, ensuring that the feed in the entire conveying zone 12 is processed uniformly.

[0045] like Figure 3 and Figure 4 As shown, multiple reverse spiral conveyor rods 39 are symmetrically arranged about the axisymmetric plane of the conveying zone 12.

[0046] Multiple reverse spiral conveyor rods 39 are evenly distributed in the conveying zone 12. This symmetrical and equidistant layout allows the feed piled up on both sides of the lower spiral conveyor rod 38 and the upper spiral conveyor rod 31 near the entrance of the output zone 13 to be conveyed in reverse at the same time. This effectively avoids excessive feed accumulation on one side, ensures the uniformity of feed distribution at the bottom of the conveying zone 12, and prevents the conveying module 3 from being worn or stuck due to excessive pressure on one side, further ensuring the stable operation of the spreading vehicle.

[0047] like Figure 4 As shown, both ends of the cutting blade 35 along the conveying direction of the upper spiral conveyor rod 31 are cutting surfaces.

[0048] The design of the two end blades of the cutting blade 35 allows it to effectively cut long-fiber feed wrapped around the conveying section of the upper spiral conveyor 31, regardless of whether the sliding rod 32 moves towards or away from the discharge end, as it rotates with the upper spiral conveyor 31 and reciprocates along the cross-thread groove 36. This significantly improves the processing efficiency of long-fiber feed and avoids conveying jams caused by fiber entanglement. Simultaneously, the design of the two end blades reduces uneven wear caused by long-term stress on a single blade of the cutting blade 35, extending its service life and reducing maintenance frequency.

[0049] The working principle of this invention is as follows: When the feed truck is working, the feed is loaded into the area where the conveying module 3 is located inside the truck body 1. The conveying module 3 conveys the feed to the output module 2, and the output module 2 then outputs the feed. When the conveying module 3 is working, the upper spiral conveying rod 31 inside it rotates. As the upper spiral conveying rod 31 rotates, the feed moves towards the discharge end under the push of the spiral blades. Simultaneously, the upper spiral conveyor rod 31 drives the sliding rod 32 to rotate synchronously. Because the traveling wheel 37 is engaged in the cross-thread groove 36 of the cross-thread column 33, the sliding rod 32 will reciprocate linearly along the trajectory of the cross-thread groove 36. The cutting blade 35 and the stirring rod 34 on the sliding rod 32 reciprocate synchronously in the through hole. When the long fiber feed is wrapped around the conveying section on the upper spiral conveyor rod 31, the cutting blade 35 will move back and forth with the sliding rod 32 to cut the wrapped long fiber feed into short segments, preventing overload of the power source and ensuring the conveying efficiency of the feed. When the feed arches or bridges above the feeding section of the upper spiral conveyor rod 31, the stirring rod 34 will rotate and stir the feed in a reciprocating manner under the drive of the sliding rod 32, so that the feed remains loose and uniform during the conveying process, preventing the feed from clumping due to accumulation and ensuring that the feed can fall smoothly.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
