Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a self-propelled silage corn harvesting device. Background Technology

[0002] When planting silage corn, it is important to consider favorable weather conditions at harvest time to facilitate silage. Harvesting equipment is used to improve efficiency during the harvesting of silage corn.

[0003] However, existing silage corn harvesting devices still have some problems in use:

[0004] An existing invention, such as Chinese Patent Application No. CN201811649676.8, describes a silage corn harvesting device for corn harvesting. This invention includes a primary header and a secondary header connected together. The primary header contains a cutter assembly, a feed roller, a primary crusher, and a feed auger connected in sequence. The secondary header contains a secondary crusher. The feed auger and the secondary crusher are connected via a feeding roller. The cutter assembly consists of a cutter drive roller and cutters circumferentially fixed to the cutter drive roller. The cutters are fixed to the cutter drive roller by cutter support seats. The feeding roller consists of a feed drive roller and feed blades circumferentially fixed to the feed drive roller.

[0005] Existing silage corn harvesting equipment can cut and recycle corn stalks normally during use, but the existing equipment uses a shredder to crush the corn stalks during harvesting, but it is difficult to ensure the uniformity and thoroughness of the crushing, and it is easy to produce stalks with large diameters.

[0006] Existing silage corn harvesting equipment uses multiple sets of horizontally arranged rotating rollers to convey corn stalks. However, this structure has poor conveying efficiency and unreliable conveying of corn stalks. It is prone to jamming due to the corn stalks shifting and falling over, which can easily lead to malfunctions.

[0007] To address the aforementioned issues, an innovative design was developed based on the existing self-propelled silage corn harvesting device. Summary of the Invention

[0008] The purpose of this invention is to provide a self-propelled corn silage harvesting device to solve the problem mentioned in the background art that existing corn harvesting devices have difficulty ensuring the uniformity and thoroughness of crushing when harvesting and crushing corn stalks, and are prone to producing large stalk diameters.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a self-propelled silage corn harvesting device, comprising a main body, a collection box, a transmission roller, and a power roller:

[0010] The rear side of the main body of the device is fixedly connected to the collection box, and the transmission rollers are symmetrically installed on the left and right sides of the main body of the device. The power rollers are symmetrically installed on the left and right sides of the collection box. A standing footboard is bolted to the rear end of the collection box, and a handrail is fixed to the top of the collection box.

[0011] The device body is equipped with a feeding mechanism at its front end. The feeding mechanism includes a first rotating rod, a feeding gear, a sliding guide rod, and a cutting blade. A first support frame is fixed to the inner wall of the device body, and the first rotating rod is rotatably connected to the first support frame. The lower end of the first rotating rod is fixed to the feeding gear. Both ends of the sliding guide rod are fixed to the inner wall of the device body, and the sliding guide rod passes through the cutting blade. The feeding mechanism is used to guide silage corn stalks into the device body and cut them off at their roots. The upper end of the second rotating rod is connected to a sprocket. The first rotating rod and the second rotating rod are arranged sequentially in the extension direction of the first support frame.

[0012] A first conveyor belt is installed at the lower middle part of the main body of the device, and a second support frame is provided at the upper end of the first conveyor belt. The second support frame is fixed to the inner wall of the main body of the device, and a cutting motor is fixed at the lower end of the second support frame. A crushing blade is connected to the upper shaft end of the cutting motor.

[0013] A straw conveying mechanism is provided above the first conveyor belt. The straw transmission structure includes a sprocket, a chain, a feeding plate, a transmission roller, and a feeding feeding plate. A second rotating rod is rotatably connected to the upper end of the first support frame. Two sets of the first support frame and the second rotating rod are arranged in front and behind each other. A chain is connected between the two sets of sprockets. The chain is connected to the feeding plate, and the feeding plates are evenly distributed outside the chain. A fixing frame is bolted to the inner wall of the main body of the device. The two ends of the transmission roller are rotatably connected to the fixing frame, and the outer wall of the transmission roller is fixedly connected to the feeding feeding plate. The straw conveying mechanism is used to continuously drive the corn silage straw backward and downward to complete the cutting and crushing.

[0014] A feeding mechanism is provided on the rear side of the first conveyor belt. The feeding mechanism includes a storage hopper, a transmission pipe and an auger shaft. The storage hopper is located at the lower rear end of the first conveyor belt and is fixed to the inner wall of the main body of the device on both the left and right sides. The transmission pipe passes through the front end of the collection box and the auger shaft is located inside the transmission pipe. The feeding mechanism is used to transfer the crushed corn silage to the inside of the collection box for storage.

[0015] Preferably, the first support frame, the first rotating rod, and the feeding gear are all arranged symmetrically in two sets, and the two sets of feeding gears are meshed and connected, and the outer wall of the feeding gear teeth is provided with a feeding groove.

[0016] By adopting the above technical solution, the meshing rotation of two sets of feeding gears can guide the silage corn stalks, so that the silage corn stalks can smoothly enter the main body of the device, and the feeding groove opened on the outer wall of the gear teeth can prevent jamming when the two sets of feeding gears rotate.

[0017] Preferably, the cutting blade is slidably connected to the sliding guide rod, and the upper end of the cutting blade is designed with an inclined surface. A transmission plate is fixed to the left rear end of the cutting blade. The lower end of the transmission plate is designed with an "L" shape, and a limit groove is opened at the lower end of the transmission plate. The lower end of the feed gear on the left side is connected to a limit rod off-center, and the lower end of the limit rod passes through the limit groove to form a sliding structure.

[0018] By adopting the above technical solution, through the cooperation between the limiting rod, the limiting groove and the transmission plate, the limiting rod can be driven to rotate around the first rotating rod when the feeding gear rotates, and the limiting rod can drive the transmission plate to move back and forth. The transmission plate can drive the cutting blade to rotate synchronously, thereby cutting off the root of the silage corn stalks.

[0019] Preferably, the sprockets and chains are symmetrically distributed on the left and right sides inside the main body of the device, and the distance between the front ends of the two sets of chains is smaller than the distance between the rear ends. The lower end of the second rotating rod passes through the first support frame, and the bottom end of the second rotating rod is connected to a driving gear. The upper end face of the feeding gear is fixed with a driven gear, and the driven gear meshes with the driving gear. The upper ends of the two sets of second rotating rods are rotatably connected to protective covers, and "U"-shaped protective grooves are opened on the left and right sides of the protective covers. The chains move inside the "U"-shaped protective grooves on both sides of the protective covers.

[0020] Using the above technical solution, the cooperation of sprockets and chains can drive multiple sets of material feeding plates to rotate synchronously. When the two sets of chains rotate, the synchronously moving material feeding plates can push the corn stalks backward, thereby further crushing and processing. When the front sprocket rotates, it can drive the second rotating rod and the drive gear to rotate. The drive gear drives the driven gear and the feeding gear to rotate synchronously, thereby providing power for the feeding mechanism.

[0021] Preferably, two sets of drive rollers are symmetrically distributed inside the main body of the device, and the feeding plates are arranged in a ring array on the outer wall of the drive rollers. The feeding plates connected to the outside of the two sets of drive rollers are staggered. The front end of the drive roller passes through the fixed frame, and the front end of the drive roller is connected to the feeding roller. The feeding roller has a conical structure design, and the outside of the feeding roller has a spiral design with raised texture. The raised textures on the outside of the two sets of feeding rollers are mirrored.

[0022] The device has a symmetrical support frame fixed to the upper end of the main body, and a flow guide is connected to the upper end of the support frame. The flow guide is designed with a curved shape at both the front and rear ends.

[0023] By adopting the above technical solution, the design of two sets of feeding rollers can guide the corn stalks during rotation and convey them backward. At the same time, the rotation of the two sets of transmission rollers drives the feeding plate to continuously move the corn stalks downward, thereby continuously cutting and crushing them.

[0024] Preferably, a bidirectional worm gear is rotatably connected to the inner rear wall of the main body of the device, and a first bevel gear is symmetrically connected to both ends of the bidirectional worm gear. A second bevel gear is fixed to the upper end of the rear sprocket, and the upper end of the second bevel gear meshes with the first bevel gear.

[0025] By adopting the above technical solution, through the cooperation of the bidirectional worm gear, the first bevel gear and the second bevel gear, the first and second bevel gears can drive the two sets of chain structures to rotate when the bidirectional worm gear rotates.

[0026] Preferably, a transmission worm gear is fixed at the rear end of the transmission roller, and the lower end of the transmission worm gear is meshed with a bidirectional worm. A groove is provided at the rear right end of the main body of the device, and a second pulley is provided inside the lower end of the groove. The second pulley is fixedly connected to the transmission roller. The right end of the bidirectional worm extends to the outside of the main body of the device, and a first pulley is fixed at the right end of the bidirectional worm. A transmission belt is connected between the first pulley and the second pulley.

[0027] By adopting the above technical solution, through the cooperation of the first pulley, the second pulley and the transmission belt, the belt structure can drive the bidirectional worm gear to rotate when the transmission wheel rotates, thereby providing rotational power for the chain structure. At the same time, the transmission worm gear can synchronously drive the two sets of transmission rollers and the feeding plate to rotate synchronously.

[0028] Preferably, the inner walls of the storage hopper are inclined to form a "V" shape, and the rear end of the first conveyor belt extends to the upper end of the storage hopper. The transmission pipe is inclined and the lower end of the transmission pipe extends into the interior of the storage hopper. The lower side of the upper end of the transmission pipe is open.

[0029] By adopting the above technical solution, the corn stalk fragments conveyed by the first conveyor belt can be temporarily collected through the design of the storage hopper. When the auger shaft rotates inside the transmission tube, it can transport the corn stalks inside the storage hopper to the collection box for collection.

[0030] Preferably, the top end of the transmission tube is rotatably connected to the auger shaft, and the top end of the auger shaft extends to the outside of the transmission tube and is connected to a bevel gear set. A second motor is fixed at the upper front end of the collection box, and the shaft end of the second motor extends into the collection box and is connected to the bevel gear set.

[0031] By adopting the above technical solution, through the cooperation of the second motor and the bevel gear set, the bevel gear set can drive the auger shaft to rotate synchronously when the second motor rotates.

[0032] Preferably, a discharge gate is installed at the lower left end of the collection box, and a second conveyor belt is embedded in the lower part of the collection box, with the inner walls of the front and rear sides of the second conveyor belt at the lower end of the collection box being inclined.

[0033] Using the above technical solution, through the cooperation of the second conveyor belt and the discharge gate, after the discharge gate is opened, the silage corn collected inside the collection box can be transported to the outside for discharge via the second conveyor belt.

[0034] Compared with the prior art, the beneficial effects of the present invention are: the self-propelled silage corn harvesting device, by setting up a feeding mechanism, can more effectively guide the silage corn stalks for feeding, and simultaneously cut off the root of the corn stalk at the lower end during the feeding process. The operation is simple. In conjunction with the straw conveying mechanism, the corn stalks are further cut and crushed during the backward conveying process, resulting in high operating efficiency. Moreover, the feeding mechanism and the straw conveying mechanism are linked together, reducing the need for a power source and lowering costs and failure rates.

[0035] 1. With the first and second conveyor belts, the chopped and crushed corn stalks can be transported and transferred, and with the help of the auger shaft structure, they can be transported to the collection box for storage. After the cutting is completed, the second conveyor belt can be used for unloading. The operation is simple and the overall efficiency is high.

[0036] 2. The straw conveying mechanism can drive the corn stalks to move downwards synchronously during the backward movement, so as to cut and crush the corn stalks evenly, ensuring the uniformity of the size of the crushed corn stalks. The chain structure, transmission rollers and feeding plates work together to prevent the corn stalks from deviating or tipping over, thus improving the reliability of the corn stalk conveying.

[0052] 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.

[0053] Please see Figures 1-14This invention provides a technical solution: a self-propelled silage corn harvesting device, comprising a main body 1, a collection box 2, a transmission roller 3, and a power roller 4. The rear side of the main body 1 is fixedly connected to the collection box 2, and the transmission roller 3 is symmetrically installed on the left and right sides of the main body 1. The power roller 4 is symmetrically installed on the left and right sides of the collection box 2. A standing footboard 5 is bolted to the rear end of the collection box 2, and a handrail 6 is fixed to the top of the collection box 2. With the forward direction of the harvesting device positioned in front of the main body 1, the power roller 4 has a built-in hub motor that can drive the power roller 4 to rotate, providing power for the harvesting device. During use, the operator can stand on the standing footboard 5 and hold the handrail 6 for stability. The design of the collection box 2 facilitates the collection of crushed corn stalks.

[0054] A feeding mechanism is provided at the front end of the main body 1 of the device. The feeding mechanism includes a first rotating rod 8, a feeding gear 9, a sliding guide rod 11, and a cutting blade 12. A first support frame 7 is fixed to the inner wall of the main body 1, and the first rotating rod 8 is rotatably connected to the first support frame 7. The lower end of the first rotating rod 8 is fixed to the feeding gear 9. Both ends of the sliding guide rod 11 are fixed to the inner wall of the main body 1, and the sliding guide rod 11 passes through the cutting blade 12. The feeding mechanism is used to guide the silage corn stalks into the interior of the main body 1 and cut them off at the root. The upper end of the second rotating rod 16 is connected to a sprocket 17. The first rotating rod 8 and the second rotating rod 16 are arranged sequentially in the extending direction of the first support frame 7. The first support frame 7, the first rotating rod 8, and the feeding gear 9 are all symmetrically arranged in two sets, and the two sets of feeding gears 9 are meshed and connected. The outer wall of the teeth of the feeding gear 9 is provided with a feeding groove 10. The cutting blade 12 is slidably connected to the sliding guide rod 11, and the upper end of the cutting blade 12 is designed with an inclined surface. Furthermore, a transmission plate 13 is fixed to the rear left side of the cutting blade 12. The lower end of the transmission plate 13 has an "L"-shaped structure design, and a limiting groove 14 is opened at the lower end of the transmission plate 13. The lower end of the left feeding gear 9 is connected to a limiting rod 15 off-center, and the lower end of the limiting rod 15 extends into the limiting groove 14 to form a sliding structure. The first support frame 7 can fix the first rotating rod 8, and the first rotating rod 8 is used to connect the feeding gear 9. When the two sets of feeding gears 9 rotate in opposite directions, the corn stalks can be guided and moved to the middle of the two sets of feeding gears 9 and conveyed backward. The feeding groove 10 opened on the outer wall of the teeth of the feeding gear 9 can prevent the corn stalks from causing the feeding gear 9 to jam. When the feeding gear 9 rotates, it can drive the limiting rod 15 to move in circles. When the limiting rod 15 rotates, it can cooperate with the limiting groove 14 to drive the transmission plate 13 and the cutting blade 12 to move back and forth, thereby cutting off the root of the corn stalks conveyed backward, so as to continue to convey them backward for crushing.

[0055] A straw conveying mechanism is installed above the first conveyor belt 21. The straw transmission structure includes a sprocket 17, a chain 18, a feeding plate 19, a transmission roller 23, and a feeding feeding plate 24. A second rotating rod 16 is rotatably connected to the upper end of the first support frame 7. Two sets of the first support frame 7 and the second rotating rod 16 are arranged front and rear. A chain 18 is connected between the two sets of sprockets 17, and the chain 18 is connected to the feeding plate 19. The feeding plates 19 are evenly distributed outside the chain 18. A fixed frame 22 is bolted to the inner wall of the device body 1. The two ends of the transmission roller 23 are rotatably connected to the fixed frame 22, and the outer wall of the transmission roller 23 is fixedly connected to the feeding feeding plate 24. The straw conveying mechanism is used to continuously drive the corn silage straw backward and downward to complete the cutting and crushing. The sprocket 17 and the chain 18 are symmetrically distributed on the left and right sides inside the device body 1, and the distance between the front ends of the two sets of chains 18 is smaller than the distance between the rear ends. The lower end of the second rotating rod 16 passes through the first support frame 7, and the bottom end of the second rotating rod 16 is connected to a drive gear. 36. A driven gear 37 is fixed to the upper end face of the feed gear 9, and the driven gear 37 meshes with the driving gear 36. A protective cover 20 is rotatably connected to the upper ends of the two sets of second rotating rods 16. "U"-shaped protective grooves are opened on both sides of the protective cover 20, and the chain 18 moves within the "U"-shaped protective grooves on both sides of the protective cover 20. Two sets of transmission rollers 23 are symmetrically distributed on the left and right sides inside the main body 1 of the device, and the feeding plates 24 are arranged in a ring array on the outer wall of the transmission rollers 23. The two sets of transmission rollers 23... The externally connected feeding plate 24 is staggered. The front end of the transmission roller 23 passes through the fixed frame 22, and the front end of the transmission roller 23 is connected to the feeding roller 25. The feeding roller 25 has a conical structure design, and the external spiral design of the feeding roller 25 has raised texture. The raised texture of the two sets of feeding rollers 25 is mirrored. The upper end of the main body 1 of the device is symmetrically fixed with a support frame 45, and the upper end of the support frame 45 is connected to a guide frame 46. The front and rear ends of the guide frame 46 are curved.The design of two sets of feeding rollers 25 allows the external raised texture to convey the corn stalks backward to the middle of the two sets of drive rollers 23 and chain 18 during rotation. Utilizing the cooperation of the two sets of sprockets 17 and chain 18, multiple sets of feed plates 19 can continuously propel the corn stalks backward while the chain 18 rotates. The protective covers 20 connected to the middle of the two sets of second rotating rods 16 prevent the chain 18 from slipping off and avoid increased wear on the chain 18 due to corn stalk compression after prolonged use. The gap between the two sets of protective covers 20 gradually increases from front to back to prevent the upper branches and leaves of the corn stalks from being damaged when moving downwards. The protective cover 20 blocks the flow of the chain 18, which is embedded in the grooves on both sides of the cover 20. This prevents the corn stalks from being scraped as they move downwards and ensures that the chain 18 remains horizontal. It also prevents the chain from falling off due to an angle between the chain 18 and the sprocket 17. When the drive roller 23 rotates, it drives multiple sets of feeding plates 24 to rotate synchronously, propelling the corn stalks downwards. Simultaneously, the rotation of the front sprocket 17 drives the second rotating rod 16 and the drive gear 36 to rotate synchronously. The drive gear 36 then drives the driven gear 37 and the feed gear 9 to rotate synchronously, thus providing power to the feeding mechanism.

[0056] A first conveyor belt 21 is installed at the lower middle part of the main body 1 of the device, and a second support frame 26 is provided at the upper end of the first conveyor belt 21. The second support frame 26 is fixed to the inner wall of the main body 1 of the device, and a cutting motor 27 is fixed at the lower end of the second support frame 26. A crushing blade 28 is connected to the upper shaft end of the cutting motor 27. During the backward conveying of corn stalks, the cutting motor 27 can drive the crushing blade 28 to rotate and cut and crush the corn stalks. In conjunction with the transmission roller 23 and the feeding plate 24, the corn stalks are driven downward to be cut and crushed at equal intervals. The cutting motor 27, the crushing blade 28 and the second support frame 26 are located in the middle of the first conveyor belt 21 and the protective cover 20. When the corn stalks pass downward through the chain 18, the crushing blade 28 rotates to crush them.

[0057] A bidirectional worm gear 29 is rotatably connected to the inner rear wall of the main body 1, and a first bevel gear 33 is symmetrically connected to both ends of the bidirectional worm gear 29. A second bevel gear 34 is fixed to the upper end of the rear sprocket 17, and the upper end of the second bevel gear 34 meshes with the first bevel gear 33. A transmission worm wheel 35 is fixed to the rear end of the transmission roller 23, and the lower end of the transmission worm wheel 35 meshes with the bidirectional worm gear 29. A groove is provided on the right rear side of the main body 1, and a second pulley 31 is provided inside the lower end of the groove. The second pulley 31 is fixedly connected to the transmission roller 3. The right end of the bidirectional worm gear 29 extends to the outside of the main body 1, and a first pulley 30 is fixed to the right end of the bidirectional worm gear 29. The first pulley 30 and the second pulley 31 are connected to each other. A transmission belt 32, which is a figure-eight belt, is connected to the intermediate part of the device. The transmission roller 3 can drive the second pulley 31 to rotate when it rotates. The second pulley 31 can drive the first pulley 30 and the bidirectional worm gear 29 to rotate synchronously through the transmission belt 32. Because the transmission belt 32 is a figure-eight belt, the bidirectional worm gear 29 rotates in the opposite direction to the transmission roller 3. When the bidirectional worm gear 29 rotates, it drives the first bevel gear 33 to rotate. The first bevel gear 33 drives the rear sprocket 17 to rotate synchronously through the second bevel gear 34. At the same time, the bidirectional worm gear 29 can cooperate with the transmission worm wheel 35 to drive the transmission roller 23 and the feeding plate 24 to rotate. The movement of this harvesting device can provide power for the straw conveying mechanism.

[0058] A feeding mechanism is provided at the rear of the first conveyor belt 21. The feeding mechanism includes a storage hopper 38, a transmission pipe 39, and an auger shaft 40. The storage hopper 38 is located at the lower rear end of the first conveyor belt 21, and its left and right sides are fixed to the inner wall of the main body 1. The transmission pipe 39 passes through the front end of the collection box 2, and the auger shaft 40 is located inside the transmission pipe 39. The feeding mechanism is used to transfer the crushed corn silage to the inside of the collection box 2 for storage. The left and right inner walls of the storage hopper 38 are inclined to form a "V" shape, and the rear end of the first conveyor belt 21 extends to the upper end of the storage hopper 38. The transmission pipe 39 is inclined, and its lower end extends into the inside of the storage hopper 38. The lower side of the upper end of the transmission pipe 39 is open.

The inner walls of the front and rear sides of the second conveyor belt 41 at the lower end of the collection box 2 are inclined. The crushed corn stalks can be transported to the storage hopper 38 for temporary storage through the first conveyor belt 21 for subsequent collection. The second motor 43 and the bevel gear set 44 work together to drive the auger shaft 40 to rotate inside the transmission tube 39, thereby transporting the crushed corn stalks into the collection box 2. When the crushed corn stalks inside the collection box 2 need to be discharged, the crushed corn stalks inside can be transported to the outside through the discharge gate 42 via the second conveyor belt 41.
