Description

Technical Field

[0001] This invention relates to the field of peanut harvester technology, specifically to a method and apparatus for simultaneously harvesting peanut pods, vines, and mulch in small hilly plots. Background Technology

[0002] Simultaneous harvesting of peanut pods, vines, and plastic film refers to the use of an integrated mechanized system to complete three core tasks at the time of peanut harvest: peanut pod collection, peanut vine cutting, and field plastic film recycling. This addresses the challenges of plastic film residue polluting the soil, the high cost and poor efficiency of manual cleaning, and the need for adaptability to small machinery in hilly areas with scattered plots, steep slopes, and complex terrain. Simultaneous harvesting of peanut pods, vines, and plastic film relies on small, adaptable machinery and a refined operational process to solve the problems of low efficiency and plastic film residue associated with traditional harvesting, while also adapting to complex terrain. During peanut harvesting, pods are mixed with plastic film and a large number of fallen leaves are mixed in with the pods. During the air separation process to separate the plastic film and pods, the fallen leaves cannot be discharged from the equipment, and the fallen leaves and pods are mixed together, resulting in a large number of fallen leaves adhering to the surface of the pods, affecting the cleanliness of the pods. At the same time, when cutting the vines, there are tilted vines that cannot enter the cutting position, resulting in uncut vines. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a device for simultaneously harvesting peanut pods, vines, and mulch film in small hilly plots, comprising: A connecting frame is provided, with a fruit bin and a plastic film bin installed at each end of the connecting frame. A vibrating screen is installed on the side of the fruit bin away from the plastic film bin, and there is a gap between the bottom of the vibrating screen and the fruit bin. The cutting mechanism and the separating mechanism are provided. The cutting mechanism is installed at the bottom of the fruit bin on the side away from the mulch bin, and the separating mechanism is installed at the top of the fruit bin. The vibrating screen is located between the cutting mechanism and the separating mechanism, and the vibrating screen is used to vibrate the soil and transfer the material from the cutting mechanism to the separating mechanism. The separation mechanism includes a connecting plate, the bottom of which is fixedly connected to the top of the fruit bin. The connecting plate is symmetrically installed along the center of the fruit bin's axis. A cover plate is fixedly installed on the top of the connecting plate, and a fan is fixedly installed on the top of the cover plate. An air guide hood is fixedly installed on the bottom of the cover plate. A connecting pipe is provided on the top of the air guide hood, and the top end of the connecting pipe penetrates the cover plate and extends to its top. The top end of the connecting pipe is connected to the air outlet of the fan through a pipe. The inner wall of the cover plate is closer to the side of the mulch bin. A fixed inclined baffle is installed. When the pods and plastic film are separated by air separation, the inclined baffle provides space for the fallen leaves mixed in with the pods to be blown out through the evenly spaced slots on the outside. During the blowing process, the inclined baffle blocks the long strips of plastic film, allowing small pieces of fallen leaves to pass through the slots and leave the device, falling to the ground. This prevents the pods and fallen leaves from mixing during harvesting and separation, which would result in a large number of fallen leaves mixed in with the pods and affect the cleanliness of the harvested pods. The end of the inclined baffle near the plastic film bin is inclined downwards, and the outer side of the inclined baffle is evenly spaced with slots.

[0004] Preferably, a transmission roller is rotatably mounted between the connecting plates, the transmission roller is symmetrically mounted along the center position of the axis of the connecting plates, and a motor is fixedly mounted on the outer side of the connecting plates, the output end of the motor is fixedly connected to one end of the transmission roller.

[0005] Preferably, a transmission belt is installed between the transmission rollers, and the top of the transmission belt does not contact the bottom of the inclined baffle. A baffle rod is fixedly installed on the top of the inner wall of the mulch film bin. The end of the baffle rod near the inclined baffle is inclined upwards and fits against the outer side of the inclined baffle. Through the cooperation of the baffle rod and the inclined baffle, when the inclined baffle guides the mulch film blown by the wind, the baffle helps the mulch film smoothly enter the mulch film bin for collection and storage. Simultaneously, during the storage process, it prevents the mulch film that has entered the mulch film bin from flying out of the bin, detaching from the equipment, and falling back to the ground after harvest, thus preventing a large amount of mulch film from remaining on the ground after harvest. The connecting plate is located near the end of the mulch film bin. Each end plate is fixedly installed, and a grid plate is fixedly installed between the end plates. A guide plate is fixedly installed at the bottom of the grid plate. Through the cooperation of the end plates and the guide plate, after the pods are conveyed to the top of the grid plate, they fall vertically under their own weight, landing on the top of the guide plate. They then move along the inclination of the guide plate away from the mulch film bin and enter the fruit bin for collection. Before the mulch film enters the mulch film bin, the direction of movement of the pods and the mulch film is changed to prevent the pods from being wrapped by the mulch film and entering the mulch film bin. The end of the guide plate away from the end plate corresponds to the feed inlet of the fruit bin. A receiving plate is fixedly installed on the inner wall of the connecting plate away from the mulch film bin. The end of the receiving plate away from the connecting plate is in contact with the outer side of the vibrating screen.

[0006] Preferably, the cutting mechanism includes a fixed plate, the side of the fixed plate near the fruit bin being fixedly connected to the outside of the fruit bin, a shovel plate being fixedly installed on the top of the fixed plate, the end of the shovel plate away from the fixed plate being inclined downwards, and the bottom of the shovel plate being lower than the bottom of the fixed plate, and side baffles being fixedly installed on both sides of the top of the shovel plate. Through the cooperation of the side baffles and the guide strip, during the forward movement, when the material subsequently scooped up pushes the material into the vibrating screen, the side baffles block the material on both sides to prevent the material from falling. At the same time, the guide strip adheres to the vibrating screen to prevent the material from getting stuck in the gaps and affecting the material conveying. The end of the shovel plate near the vibrating screen is fixedly installed with the guide strip.

[0007] Preferably, a fixed frame is fixedly installed on the outer side of the fixed plate, and a movable toothed plate is slidably installed on the inner wall of the fixed frame. Cutting motors are fixedly installed on both sides of the top of the fixed frame. The output end of the cutting motor is fixedly connected to both ends of the movable toothed plate through a camshaft. A fixed toothed plate is fixedly installed at the bottom of the fixed frame, and the top of the fixed toothed plate is tightly fitted with the bottom of the movable toothed plate. A bottom stop strip is fixedly installed at the bottom of the fixed frame. The end of the bottom stop strip away from the fixed frame is curved upward. The bottom stop strip, in conjunction with the fixed toothed plate and the movable toothed plate, cuts the vines. Before cutting, the bottom stop strip contacts the ground to lift the vines, preventing them from tilting and failing to contact the cutting position, thus affecting the cutting effect. An arc-shaped baffle is fixedly installed at the top of the fixed frame.

[0008] A method for simultaneously harvesting peanut pods, vines, and mulch film in small hilly plots consists of the following steps: S1. Vine cutting: The vines are cut by shearing before the pods are scooped up, and the vines are pushed to both sides as the device moves forward. S2. Pod harvesting: After the vines are cut, the pods, plastic film and soil are shoveled up at the same time, so that the pods, plastic film and soil are pushed to the vibration position at the same time as the device moves forward. S3. Soil separation: During the simultaneous transport of pods, mulch film, and soil, the soil is separated by a vibrating screen. S4. Mulch film separation: After soil separation, the mixture of mulch film and pods is blown by air separation, so that the lighter mulch film is separated from the pods by the wind and moves along different paths for separate storage.

[0009] The mulch film separation process involves the simultaneous separation of fallen leaves, pods, and mulch film. Wind power is used to blow the mulch film and fallen leaves out of the equipment while simultaneously blocking the mulch film, keeping it inside. When the wind blows the pods and mulch film, the mulch film is lifted by the wind, while the pods, unable to be lifted by the wind, fall downwards and are collected under gravity. The mulch film moves along the blowing path, thus separating the pods from the mulch film.

[0010] This invention provides a device for simultaneously harvesting peanut pods, vines, and mulch in small hilly plots. It has the following beneficial effects: (i) The device for simultaneously harvesting peanut pods, vines and plastic film in this small hilly plot uses inclined baffles to separate pods and plastic film by air separation. The evenly spaced slots on the outside provide space for the fallen leaves mixed in the pods to be blown out. During the blowing process, the inclined baffles block the long strips of plastic film, allowing small pieces of fallen leaves to pass through the slots and leave the device, falling to the ground. This prevents the pods and fallen leaves from mixing during harvesting and separation, which would result in a large amount of fallen leaves mixed in the pods and affect the cleanliness of the harvested pods.

[0011] (ii) The device for simultaneously harvesting peanut pods, vines and plastic film in this small hilly plot uses a baffle bar and an inclined baffle to guide the plastic film blown by the wind. The inclined baffle guides the plastic film smoothly into the plastic film bin for collection and storage. At the same time, during the storage process, it prevents the plastic film that has entered the plastic film bin from flying out of the bin and falling back to the ground after the wind enters the bin, thus preventing a large amount of plastic film from remaining on the ground after harvest.

[0012] (III) The device for simultaneously harvesting peanut pods, vines and plastic film in this small hilly plot, through the cooperation of end plate and guide plate, after the pods are transported to the top of the grid plate, the pods fall vertically under their own weight, fall to the top of the guide plate, and move away from the plastic film bin along the inclination of the guide plate, and enter the fruit bin for collection. Before the plastic film enters the plastic film bin, the direction of movement of the pods and plastic film is changed to prevent the pods from being wrapped by the plastic film and entering the plastic film bin.

[0013] (iv) The device for simultaneously harvesting peanut pods, vines and mulch in this small hilly area uses side baffles and guide bars to block the material from falling off when it is pushed into the vibrating screen by the material being scooped up later. At the same time, the guide bars are attached to the vibrating screen to prevent the material from getting stuck in the gaps and affecting the material conveying.

[0014] (v) The device for simultaneously harvesting peanut pods, vines and mulch in this small hilly plot uses a bottom baffle in conjunction with a fixed toothed plate and a moving toothed plate to cut the vines. Before cutting, the bottom baffle contacts the ground to lift the vines and prevent them from tilting and failing to reach the cutting position, thus affecting the cutting effect.

[0017] 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.

[0018] For the first embodiment, please refer to... Figures 1 to 2 and Figures 5 to 9 The present invention provides a technical solution: A device for simultaneously harvesting peanut pods, vines, and mulch film in a small hilly area includes: A connecting frame 1 is provided, with a fruit bin 6 and a plastic film bin 5 installed at both ends of the connecting frame 1 respectively.

The vibrating screen 3 is located between the cutting mechanism 2 and the separating mechanism 4, and the vibrating screen 3 is used to vibrate the soil and transfer the material from the cutting mechanism 2 to the separating mechanism 4. The separation mechanism 4 includes a connecting plate 401. The bottom of the connecting plate 401 is fixedly connected to the top of the fruit bin 6, and the connecting plate 401 is symmetrically installed along the center of the axis of the fruit bin 6. A cover plate 402 is fixedly installed on the top of the connecting plate 401, and a fan 403 is fixedly installed on the top of the cover plate 402.

The top end of the connecting pipe is connected to the air outlet of the fan 403 through a pipe. The fan 403 generates airflow, which is then introduced into the air guide hood 408 through the pipe. The air is blown out through the air guide 408, which blows the plastic film and fallen leaves mixed in the pods, causing the plastic film and fallen leaves to move quickly towards the plastic film storage 5 under the wind. During the movement, the long strip of plastic film is blocked by the inclined baffle 409, allowing the fallen leaves to pass through the slots of the inclined baffle 409 and be blown out of the equipment. At the same time, the wind blows the plastic film, and guided by the inclined baffle 409 and the baffle rod 407, the plastic film is blown into the plastic film storage 5 for collection and storage. The inclined baffle 409 is fixedly installed on the inner wall of the cover plate 402 near the side of the plastic film storage 5. The end of the inclined baffle 409 near the plastic film storage 5 is inclined downward, and the outer side of the inclined baffle 409 is evenly provided with slots.

[0019] A transmission roller 411 is rotatably mounted between the connecting plates 401. The transmission roller 411 is symmetrically mounted at the center position of the axis of the connecting plates 401. The transmission belt 405 drives the pods to move, so that the pods reach the top of the grid plate 412. Under their own gravity, the pods fall from the slot of the grid plate 412 and fall to the top of the guide plate 410. Through the inclination of the guide plate 410, they are guided to the fruit bin 6 for collection. A motor 406 is fixedly mounted on the outside of the connecting plates 401. The output end of the motor 406 is fixedly connected to one end of the transmission roller 411.

[0020] A transmission belt 405 is installed between the transmission rollers 411. The top of the transmission belt 405 does not contact the bottom of the inclined baffle 409. A baffle rod 407 is fixedly installed on the top of the inner wall of the mulch film storage 5. The end of the baffle rod 407 near the inclined baffle 409 is inclined upwards and fits against the outer side of the inclined baffle 409. An end plate 413 is fixedly installed on the end of the connecting plate 401 near the mulch film storage 5. A grid plate 412 is fixedly installed between the end plates 413. After the soil is separated by the vibrating screen 3, the pods and mulch film are connected by... The material plate 404 is guided to the top of the transmission belt 405, and then the transmission roller 411 is driven to rotate by the motor 406, so that the transmission belt 405 moves and drives the pods and mulch film to approach the grid plate 412. The bottom of the grid plate 412 is fixedly installed with a guide plate 410. The end of the guide plate 410 away from the end plate 413 corresponds to the feed inlet of the fruit bin 6. The inner wall of the connecting plate 401 is fixedly installed with a receiving plate 404 away from the mulch film bin 5. The end of the receiving plate 404 away from the connecting plate 401 is in contact with the outer side of the vibrating screen 3.

[0021] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 3 to 4 As shown, the cutting mechanism 2 includes a fixed plate 201. The side of the fixed plate 201 closest to the fruit bin 6 is fixedly connected to the outside of the fruit bin 6. A shovel plate 202 is fixedly installed on the top of the fixed plate 201. The end of the shovel plate 202 away from the fixed plate 201 is inclined downward, and the bottom of the shovel plate 202 is lower than the bottom of the fixed plate 201. The cutting motor 205 is connected to both ends of the moving tooth plate 206 through a camshaft, so that the moving tooth plate 206 reciprocates inside the fixed frame 204, so that the teeth between the moving tooth plate 206 and the fixed tooth plate 209 interlock. During the interlocking process, the vines are cut. At the same time, during the cutting, the bottom of the bottom baffle 210 contacts the ground and lifts the vines. After the vines are cut, the arc baffle 207 pushes the vines. Side baffles 208 are fixedly installed on both sides of the top of the shovel plate 202. A guide strip 203 is fixedly installed on the end of the shovel plate 202 closest to the vibrating screen 3.

[0022] A fixed frame 204 is fixedly installed on the outer side of the fixed plate 201. A movable toothed plate 206 is slidably installed on the inner wall of the fixed frame 204. Cutting motors 205 are fixedly installed on both sides of the top of the fixed frame 204. The output end of the cutting motor 205 is fixedly connected to both ends of the movable toothed plate 206 through a camshaft. A fixed toothed plate 209 is fixedly installed on the bottom of the fixed frame 204. The top of the fixed toothed plate 209 is tightly fitted with the bottom of the movable toothed plate 206. During the forward movement, the arc shape of the arc baffle 207 is utilized. The cut seedlings are pushed to both sides, and the shovel 202 is inserted into the soil under the drive of the traction device. During the forward movement, the material shoveled is restricted by the side baffle 208, so that it is guided by the guide bar 203 under the pressure of the material shoveled in the next step and enters the vibrating screen 3. The bottom of the fixed frame 204 is fixedly installed with a bottom baffle 210. The end of the bottom baffle 210 away from the fixed frame 204 is curved upward. The top of the fixed frame 204 is fixedly installed with an arc baffle 207.

[0023] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figure 10 As shown, a method for simultaneously harvesting peanut pods, vines, and mulch in a small hilly area consists of the following steps: S1. Vine cutting: The vines are cut by shearing before the pods are scooped up, and the vines are pushed to both sides as the device moves forward. S2. Pod harvesting: After the vines are cut, the pods, plastic film and soil are shoveled up at the same time, so that the pods, plastic film and soil are pushed to the vibration position at the same time as the device moves forward. S3. Soil separation: During the simultaneous transport of pods, mulch film, and soil, the soil is separated by a vibrating screen. S4. Mulch film separation: After soil separation, the mixture of mulch film and pods is blown by air separation, so that the lighter mulch film is separated from the pods by the wind and moves along different paths for separate storage.

[0024] The mulch film separation process involves the simultaneous separation of fallen leaves, pods, and mulch film. Wind power is used to blow the mulch film and fallen leaves out of the equipment while simultaneously blocking the mulch film, keeping it inside. When the wind blows the pods and mulch film, the mulch film is lifted by the wind, while the pods, unable to be lifted by the wind, fall downwards and are collected under gravity. The mulch film moves along the blowing path, thus separating the pods from the mulch film.

[0025] In use, the traction device is connected to the connecting frame 1. The traction device drives the peanut planting path of the device. During the movement, the cutting mechanism 2 first cuts the vines, and then the cutting mechanism 2 scoops up the pods, soil and mulch film. As it moves forward, it pushes them into the vibrating screen 3. The vibrating screen 3 drives them into the separation mechanism 4, while vibrating them. The soil is loosened by the vibration and passes through the vibrating screen 3, falling to the ground through the gap between the vibrating screen 3 and the pod bin 6. Then the pods and mulch film enter the separation mechanism 4. The separation mechanism 4 separates the mulch film and pods, so that the mulch film and pods are collected in the mulch film bin 5 and the pod bin 6 respectively.

[0026] In the cutting mechanism 2, the cutting motor 205 is connected to both ends of the moving toothed plate 206 via a camshaft, causing the moving toothed plate 206 to reciprocate inside the fixed frame 204. This causes the teeth of the moving toothed plate 206 and the fixed toothed plate 209 to interlock repeatedly, cutting the seedlings during the interlocking process. Simultaneously, during the cutting, the bottom of the bottom baffle 210 contacts the ground, lifting the seedlings. After the seedlings are cut, the arc baffle 207 pushes the seedlings forward. During the forward movement, the arc shape of the arc baffle 207 pushes the cut seedlings to both sides. At the same time, the shovel plate 202 is inserted into the soil under the drive of the traction device. During the forward movement, the side baffle 208 restricts the shoveled material, allowing it to be guided by the guide bar 203 under the pressure of the subsequently shoveled material and enter the vibrating screen 3.

[0027] In the separation mechanism 4, after the soil is separated by the vibrating screen 3, the pods and mulch film are guided to the top of the transmission belt 405 through the receiving plate 404. Then, the transmission roller 411 is driven by the motor 406 to rotate, causing the transmission belt 405 to move and move the pods and mulch film closer to the grid plate 412. During the approach process, the fan 403 generates wind, which is introduced into the air guide hood 408 through the pipe and blown out by the air guide hood 408, blowing the mulch film and fallen leaves mixed in the pods. Under the wind, the mulch film and fallen leaves are quickly transported towards the mulch film bin 5. During the movement, the long strip of plastic film is blocked by the inclined baffle 409, causing the fallen leaves to pass through the slot of the inclined baffle 409 and be blown out of the equipment. At the same time, the wind blows the plastic film, and through the guidance of the inclined baffle 409 and the baffle rod 407, the plastic film is blown into the plastic film bin 5 for collection and storage. The transmission belt 405 drives the pods to move, so that the pods reach the top of the grid plate 412, and fall from the slot of the grid plate 412 under their own gravity, falling to the top of the guide plate 410. Through the inclination of the guide plate 410, the pods are guided to the fruit bin 6 for collection.

8. A method for simultaneously harvesting peanut pods, vines, and mulch film in a small hilly area, characterized in that, It consists of the following steps: S1. Vine cutting: The vines are cut by shearing before the pods are scooped up, and the vines are pushed to both sides as the device moves forward. S2. Pod harvesting: After the vines are cut, the pods, plastic film and soil are shoveled up at the same time, so that the pods, plastic film and soil are pushed to the vibration position at the same time as the device moves forward. S3. Soil separation: During the simultaneous transport of pods, mulch film, and soil, the soil is separated by a vibrating screen. S4. Mulch film separation: After soil separation, the mixture of mulch film and pods is blown by air separation, so that the lighter mulch film is separated from the pods by the wind and moves along different paths for separate storage.

9. A method for simultaneously harvesting peanut pods, vines, and mulch film in a small hilly area according to claim 8, characterized in that: The mulch film separation process involves the simultaneous separation of fallen leaves, pods, and mulch film. Wind power is used to blow the mulch film and fallen leaves out of the equipment while simultaneously blocking the mulch film, thus keeping it inside the equipment.

10. A method for simultaneously harvesting peanut pods, vines, and mulch film in a small hilly area according to claim 9, characterized in that: When the wind blows the pods and the plastic film, the plastic film is lifted by the wind, while the pods cannot be lifted by the wind and fall downwards to be collected under the action of gravity. The plastic film moves along the blowing path, causing the pods to separate from the plastic film.
