Description

Technical Field

[0001] This utility model belongs to the agricultural field and relates to peanut field vine and fruit separation machinery, specifically a peanut harvester equipped with a chain-type peanut vine picking and lifting machine with fruit attached. Background Technology

[0002] Currently, peanut harvesting in the field is mostly accomplished by a combination of a tractor-pulled tiller and a towed peanut harvester that separates the stalks and pods. The existing towed peanut harvester includes a frame, wheels mounted on the frame, a peanut stalk and pod-collecting elevator mounted on one side of the frame, a pod thresher mounted at the rear of the frame, a peanut pod cleaning screen mounted on the frame and below the pod thresher, a horizontal (fan shaft in the vertical direction) cleaning fan mounted in front of the peanut pod cleaning screen (in the direction of peanut movement), a peanut pod elevator mounted on the frame and connected to the front of the peanut pod cleaning screen, and a peanut pod loading box mounted at the front of the frame. The front end of the frame has a traction rod connected to the tractor and a power input shaft connected to the tractor's rotation output. The power shaft distributes power to each rotating component via a gearbox. The threshing device includes an outer cover with an opening on the lower side, a threshing roller with a rotating shaft in the direction of the separator's travel inside the outer cover, and a threshing fixing grate surrounding the roller. The tail of the roller (in the direction of peanut vine movement) has a peanut vine centrifugal throwing impeller, and the outer cover of the threshing device corresponding to the position of the impeller has a peanut vine discharge outlet. The front half of the fixing grate (the position that receives the falling peanut vines) is a semi-cylindrical shape lacking the upper circumference, and the rear half of the fixing grate connected to the semi-cylindrical part (extending in the direction of peanut vine travel) is a complete cylindrical shape with the same diameter as the front half.

[0003] While existing tractor-driven peanut harvesters are widely used in peanut harvesting operations, as manufacturers of vine-fruit separators, we have found through communication with users that this equipment has significant shortcomings under certain working conditions: when the peanut vines have a high soil content or the vine pile is large, the peanut vine picking and lifting machine with fruit cannot effectively lift them, often resulting in the peanut vines with fruit rolling in place at the initial lifting and feeding position, making them difficult to transport.

[0004] The root cause lies in the fact that existing peanut harvesters all employ belt conveyor structures: on the one hand, the material at the initial lifting position cannot be effectively fed, resulting in insufficient feeding stability; on the other hand, if the material conveying is interrupted midway, the peanut vines that have been lifted to the upper part of the conveyor belt will slide down in the opposite direction of lifting. These two major problems directly lead to a significant decrease in equipment operating efficiency. Therefore, there is an urgent need to develop a peanut harvester equipped with a chain-type peanut vine picking and lifting machine to completely solve the above pain points and ensure the continuous stability of peanut vine feeding and lifting. Utility Model Content

[0005] In view of the above problems, the purpose of this utility model is to provide a peanut harvester equipped with a chain-type peanut vine picking and lifting machine to ensure the continuous stability of peanut vine feeding and lifting, so as to overcome the shortcomings of the prior art.

[0006] This utility model provides a peanut harvester equipped with a chain-type peanut vine picking and lifting machine, comprising: a frame, wheels mounted on the frame, a peanut vine picking and lifting machine mounted on one side of the frame, a threshing unit mounted at the rear of the frame, a peanut vine removal screen mounted on the frame and located below the threshing unit, a horizontal removal fan mounted in front of the peanut vine removal screen, a peanut lifting machine mounted on the frame and connected to the front end of the peanut vine removal screen, and a peanut loading box mounted at the front of the frame. The front end of the frame has a drawbar connected to a tractor and a power input shaft connected to the tractor's rotational output. The peanut vine picking and lifting machine is used to lift peanut vines with vines from the ground into the threshing unit or extend to the horizontal conveyor belt of the threshing unit. The improvement is that the peanut vine picking and lifting machine is a chain-type peanut vine picking and lifting machine. The peanut vine picking and lifting machine includes: a lifting frame mounted on a machine frame; a conveying channel mounted on the lifting frame and inclined upwards; and a chain conveyor belt located on the conveying channel. The chain conveyor belt includes: at least one set of chains that rotate cyclically along the conveying channel; a set of driving sprockets and driven sprockets rotatably connected to the lifting frame; and feeding combs mounted on the chain perpendicularly or nearly perpendicularly to the chain. The chain meshes with the driving sprockets and driven sprockets and rotates cyclically on the front and back of the conveying channel via the driving sprockets and driven sprockets. Multiple feeding combs are arranged on the chain along the direction of chain movement. The driving sprockets receive power from the power input shaft. The driving sprockets and driven sprockets drive the chain to rotate cyclically along the conveying channel and drive the feeding combs on the chain to lift and convey the peanut vines on the conveying channel.

[0007] As a preferred embodiment of this utility model, the material conveying channel is composed of a lifting end and a discharging end that are connected or integrally formed, and the discharging end is bent downward relative to the lifting end.

[0008] As a preferred embodiment of this invention, the lifting end is bent downwards at a angle of 15° to 60° relative to the lifting end.

[0009] As a preferred embodiment of this utility model, two chains are arranged in parallel, with the two chains being of equal length. The drive sprockets that cooperate with the two chains are of equal diameter and coaxially driven. Multiple feeding combs are evenly distributed and fixedly connected to the chains, and the two ends of the feeding combs are fixedly connected to the two chains by bolts.

[0010] As a preferred embodiment of this utility model, the feeding comb includes: a comb bar and comb rods, with multiple comb rods fixedly connected to the comb bar, and the two ends of the comb bar being fixedly connected to two adjacent chains by bolts.

[0011] As a preferred embodiment of this invention, a plurality of the aforementioned comb-pulling short rods are evenly distributed and fixedly connected to the comb bar, and the comb-pulling short rods are curved L-shaped.

[0012] The bending direction of the L-shaped comb bar is arranged in the opposite direction to the conveying direction.

[0013] As a preferred embodiment of this invention, the comb bar is wrapped with a soft rubber anti-collision sheet.

[0014] As a preferred embodiment of this utility model, the material conveying channel is composed of a base plate surrounding the chain conveyor belt and baffles on both sides of the base plate. The base plate is located below the chain conveyor belt and has multiple hollow holes.

[0015] As a preferred embodiment of this invention, the driving sprocket is arranged at the top of the conveying channel, the driven sprocket is arranged at the bottom and back of the conveying channel, and the chain is sequentially engaged with the driving sprocket and the driven sprocket to realize the chain cyclically rotating around the bottom plate of the conveying channel.

[0016] As a preferred embodiment of this utility model, the power input shaft connected to the tractor's rotational output inputs power to the power shaft via a gearbox, and the power shaft is connected to a pulley that rotates coaxially with the drive sprocket via a pulley through the gearbox.

[0017] The advantages and positive effects of this utility model are:

[0018] 1. This utility model uses a chain-type peanut vine picking and conveying machine to lift and transport peanut vines with fruit. Compared with conveyor belt elevators, it is not only more efficient, but also has a lower failure rate.

[0019] 2. This utility model adds a downward-extending unloading section channel at the top of the conveying channel, so that the peanut vines with fruit after passing the top of the conveying channel can automatically fall from the unloading section channel according to their own weight.

[0020] 3. This utility model uses a chain in conjunction with a feeding comb to replace the conveyor belt for lifting peanut vines. The feeding comb helps to fix the peanut vines, ensuring that peanut vines with varying soil content can be effectively lifted. Furthermore, due to the restriction of the short comb rod during the lifting process, it can further ensure that the peanut vines will not slip off the conveying channel due to their weight. In addition, since the bending direction of the short comb rod is arranged in the opposite direction of the conveying (upward lifting) direction, it is ensured that after being lifted to the highest point of the conveying channel, its bending angle will not affect the falling of the peanut vines.

[0021] 4. The feeding comb of this utility model is covered with a soft rubber anti-collision sheet to improve its service life and reduce the risk of peanuts being bumped or knocked.

[0022] 5. The two ends of the feeding comb of this utility model are fixed to the chain by bolts. Compared with the integrated conveyor belt, the worn parts are easier to replace.

[0023] 6. The bottom plate of the material conveying channel of this utility model is a hollow plate structure located below the feeding comb, so that the soil on the peanut vines with fruit can fall through the hollow position. Attached Figure Description

[0033] In the following description, numerous specific details are set forth for illustrative purposes and to provide a thorough understanding of one or more embodiments. However, it will be apparent that these embodiments may also be implemented without these specific details. In other instances, well-known structures and devices are shown in block diagram form for ease of description of one or more embodiments.

[0034] See Figure 1-8This embodiment of a peanut harvester equipped with a chain-type peanut vine picking and lifting machine includes: a frame 1, wheels 2 mounted on the frame 1, a chain-type peanut vine picking and lifting machine 3 mounted on one side of the frame 1, a threshing device 4 mounted at the rear of the frame, a peanut vine removal screen 5 mounted on the frame 1 and located below the threshing device 4, a horizontal removal fan 6 mounted in front of the peanut vine removal screen 5, a peanut lifting machine 7 mounted on the frame 1 and connected to the front end of the peanut vine removal screen 5, and a peanut loading box 8 mounted at the front of the frame 1. The front end of the frame 1 has a drawbar 9 connected to a tractor and a power input shaft 10 connected to the tractor's rotational output. The power input shaft 10 distributes power to the various rotating parts via a gearbox. Box 11, chain-type peanut vine picking and lifting machine 3 is used to lift peanut vines with fruit from the ground into or extend to the fruit remover 4 via a horizontal conveyor belt. The chain-type peanut vine picking and lifting machine 3 includes: a lifting frame 301 mounted on a machine frame; a conveying channel 302 mounted on the lifting frame 301 and inclined upwards; a chain conveyor belt located on the conveying channel 302; the conveying channel 302 is hinged to the top of the lifting frame 301; the conveying channel 302 is connected to the middle or lower part of the lifting frame 301 via a hydraulic cylinder 12; the hydraulic cylinder 12 can adjust the inclination angle of the conveying channel 302 relative to the ground; the chain conveyor belt includes: a set of two belts that rotate cyclically along the conveying channel 302. The system includes a chain 303, a set of two drive sprockets (not shown) rotatably connected to the lifting frame 301, five sets of ten driven sprockets 305, and a feeding comb 306 located between the two chains 303. The chains 303 are sequentially engaged with the drive sprockets 305 and the driven sprockets 306, and rotate cyclically on the front (feeding side) and back (facing the ground) of the conveying channel 303 under the drive of the drive sprockets 305 and the driven sprockets 306. The drive sprockets are located at the top of the conveying channel 302. The multiple feeding combs 306 are evenly distributed along the length of the chains 303. Bolt holes are provided at both ends of the feeding combs 306, and feeding combs are evenly distributed on the opposite edges of the two chains 303. The L-shaped bolt connecting seat 307 is used to fasten the two ends of the feeding comb 306 to the L-shaped bolt connecting seat 307 of the chain 303 by bolts. The feeding comb 306 includes: comb bar 308 and comb short rod 309. Multiple comb short rods 309 are evenly distributed and fastened to the comb bar 308. The two ends of the comb bar 308 of the feeding comb 306 are fastened to the L-shaped bolt connecting seat 307 of the chain 303 by bolts. The comb short rod 309 is curved L-shaped. The bending direction of the L-shaped comb short rod 309 is arranged in the opposite direction to the conveying (upward lifting) direction. The comb bar 308 is wrapped with a soft rubber anti-collision plate. The soft rubber anti-collision plate can not only extend the service life of the comb bar 308, but also reduce the breakage rate of peanuts.

[0035] Furthermore, in this embodiment, the material conveying channel 302 is composed of an integrally formed lifting end 310 and a discharging end 311. The discharging end 311 is inclined downward in the opposite direction of the material conveying direction. The angle between the lifting end 310 and the discharging end 311 is less than 180 degrees, so that the peanut vines lifted to the end position of the lifting end 310 can slide off the discharging end 311 by their weight, thereby solving the problem of peanut vines getting caught on the feeding comb 306.

[0036] Furthermore, in this embodiment, the material conveying channel 302 is composed of a bottom plate 312 surrounding the chain conveyor belt and baffles 304 on both sides of the bottom plate 312. The bottom plate 312 is located below the chain conveyor belt, and multiple hollow holes are provided on the bottom plate 312 to facilitate the falling off of the soil mixed in with the peanut vines.

[0037] Furthermore, in this embodiment, the driving sprocket is arranged at the top of the conveying channel 302 near the unloading end 311, and multiple driven sprockets 305 are arranged sequentially at the bottom and back of the conveying channel 302. A tensioning wheel 15 is added between two driven sprockets 305 to ensure the stability of the chain transmission. The chain 303 is sequentially engaged with the driving sprocket, the driven sprockets 305, and the tensioning wheel, so that the chain 303 can rotate cyclically around the bottom plate of the conveying channel 302.

[0038] Furthermore, in this embodiment, the power input shaft 10 connected to the tractor's rotation output inputs power to the gearbox. The gearbox distributes the power to the transfer gearbox 11 through the transfer power shaft. The transfer gearbox 11 is connected to the synchronous pulley that rotates coaxially with the drive sprocket through the transfer chain 14. The drive sprocket receives the power from the power input shaft 10. The drive sprocket and the driven sprocket 305 drive the chain 303 to rotate cyclically along the conveying channel 302, and drive the feeding comb 306 on the chain 303 to push the peanut seedlings with fruit on the conveying channel 302 for lifting and conveying.

[0039] In this embodiment, the comb rod 306 is designed as a curved L-shape. The bending direction of the L-shaped comb rod 306 is arranged in the opposite direction to the conveying (upward lifting) direction. The purpose is as follows: Under normal circumstances, in order to prevent peanut vines from falling during the lifting process, the bending direction of the comb rod 309 should be towards the lifting direction, so as to hook the peanut vines and prevent them from sliding back. However, since the chain 303 is a cyclic conveying form, the feeding comb 306 also rotates cyclically around the conveying channel 302. When the feeding comb 306 runs to the highest point of the conveying channel 302, the bending direction of the comb rod 309 will reverse. Its curved structure will hook the peanut vines and make them fall from the end position, thus playing a counteracting role. In this embodiment, the bending direction of the comb rod 309 is arranged in the opposite direction to the conveying direction. Experiments have shown that it can not only prevent peanut vines from sliding back during the lifting process, but also play a guiding role when they fall at the end position of the conveying channel.

[0040] Furthermore, in this embodiment, a pressing rake 13 is provided at the bottom of the conveying channel 302 near the ground. The pressing rake is hinged to the two side walls of the conveying channel 302, and the teeth of the pressing rake 13 face the lifting direction. The pressing rake 13 squeezes and lifts the peanut vines by its own weight.

[0041] Working principle: Peanut vines are propelled into the conveying channel 302 by the feeding comb 306. The chain-type peanut vine picking and lifting machine 3 with fruit in the conveying channel 302 lifts the peanut vines from the bottom to the top of the conveying channel 302. The top of the conveying channel 302 is also equipped with a downwardly inclined unloading end 311. With the swinging of the feeding comb 306, the vines quickly enter the next stage of vine-fruit separation. The chain-type peanut vine picking and lifting machine 3 with fruit uses a chain drive and a lifting device composed of multiple feeding combs 306. The feeding combs 306, as wear parts, are bolted to the chain 303. The feeding combs 306 use comb bars 308 parallel to the lifting direction and short comb rods 309 evenly distributed on the comb bars 308 to lift the peanut vines. The presence of the short comb rods 309 can lift peanut vines with too much soil, thus effectively solving the slippage problem of the conveyor belt in the existing technology.

[0042] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
