Description

Technical Field

[0001] This utility model relates to agricultural machinery, specifically a digging, vibrating, harvesting, and peanut harvesting platform. Background Technology

[0002] For a long time, peanut planting, harvesting, and processing have relied heavily on manual labor, resulting in high labor intensity and low efficiency. In the entire peanut production process, the harvesting stage accounts for more than one-third of the total labor and over 50% of the total production cost. Developing mechanized peanut harvesting is of practical significance for reducing operating costs, improving efficiency, and increasing farmers' income.

[0003] Peanut harvesters are crop harvesting machines that complete tasks such as digging up peanuts, separating soil, spreading strips, picking peanuts, cleaning, and collecting peanuts during the peanut harvesting process. Existing peanut harvesters generally have the following problems: (1) The depth of the digging shovel into the soil needs to be manually controlled, resulting in high labor intensity, difficult operation, and low work efficiency; (2) During the peanut harvester's movement and when turning around in the field, the height of the cutting platform needs to be adjusted at any time to ensure a suitable height. The existing cutting platform height adjustment mostly relies on pure mechanical operation, which requires a lot of manpower and material resources and has low adjustment efficiency, thereby reducing the work efficiency of the peanut harvester. Summary of the Invention

The tensioning mechanism and the second guide rail apply an inward thrust to the clamping chain. The peanut vines and pods are clamped by the relative movement between the two clamping chains and the tensioning force of the tensioning mechanism.

[0009] The tensioning mechanism includes: The tensioning shaft has one end connected to the second guide rail via a pin, and the other end is slidably mounted in the fixed sleeve. A compression spring is provided on the annular outer side of the tensioning shaft. The fixing sleeve is fixedly connected to the cutting table frame.

[0010] The earth-shaking swing mechanism includes: The drive shaft has a drive sprocket fixed at one end and an eccentric shaft fixed at the other end. The eccentric shaft is eccentrically rotatably connected to the upper end of the connecting rod, and the drive shaft is rotatably connected to the cutting table frame. The first bearing sleeve is located at the lower end of the connecting handle, and the upper end of the connecting handle is connected to the lower end of the connecting rod. During the rotation of the transmission shaft, the first bearing sleeve is driven to reciprocate up and down through the connecting rod and the connecting handle. Two sets of hanging plates are respectively set on both sides along the transmission direction of the clamping chain. Each set of hanging plates includes one active hanging plate and several passive hanging plates. The upper end of the active hanging plate is fixedly connected to the connecting shaft.

Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many ways other than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1 and Figure 2 As shown, the excavating, vibrating, and picking header of this utility model includes a header frame 1. The header frame 1 is arranged front-to-back along the forward direction of the peanut harvester, and a clamping device 11 is provided along the length of the header frame 1. The front end of the header frame 1 is provided with a peanut digging mechanism 7, a vine straightener 8, and a depth limiting mechanism 9. The bottom of the header frame 1 is provided with a vibrating swing mechanism 2 and a peanut picking mechanism 4 in sequence along the front-to-back direction. The rear end of the header frame 1 is provided with a tensioning and guiding mechanism 13. A header lifting mechanism 5 connects the header frame 1 to the traveling device that enables the entire peanut harvester to move. During operation, the header frame 1 is in a forward-lower-rear-high position.

[0020] like Figure 3 and Figure 4As shown, the peanut digging mechanism 7 includes two symmetrically arranged shovels 704. The shovels 704 are located at the front bottom of the header frame 1, and are fixedly connected to the header frame 1 via a cylindrical handle 702 and a limiting bending plate 701. A blade fixing plate 705 is fixed to the front end of the cylindrical handle 702, and the shovels 704 are fixed on the blade fixing plate 705. In this embodiment, in order to improve the connection strength between the limiting bending plate 701 and the blade fixing plate 705, a reinforcing plate 703 is also provided between the cylindrical handle 702 and the blade fixing plate 705. The reinforcing plate 703 can greatly improve the connection strength between the cylindrical handle 702 and the blade fixing plate 705.

[0021] After the 704 shovel is inserted into the soil, it digs up the peanut roots, cuts the root hairs, and digs up the peanut fruit.

[0022] Two vine straighteners 8 are symmetrically arranged at the front end of the cutting platform 1, with each vine straightener positioned above the shovel 704. After the shovel 704 digs the peanuts out of the soil, the vine straighteners 8 on both sides straighten the peanut vines, allowing them to smoothly enter the clamping mechanism 11 and be held in place. This application uses existing vine straighteners without making any improvements to their structure; therefore, this application does not provide a detailed description of the vine straightener's structure.

[0023] The front end of the cutting platform 1 is also equipped with a depth limiting mechanism 9. For example... Figure 9 As shown, the depth limiting mechanism 9 includes a depth limiting wheel 905 and a depth limiting cylinder 904. The depth limiting wheel 905 is located on one side of the front end of the cutting table frame 1 and is located outside the blade 704. The depth limiting wheel 905 is mounted on a depth limiting wheel bracket 906. The depth limiting wheel 905 is rotatably connected to the lower end of the depth limiting wheel bracket 906, and the upper end of the depth limiting wheel bracket 906 is connected to the cutting table frame 1 in sequence through a connecting plate 903 and a bracket shaft 901.

[0024] In this embodiment, the upper end of the depth-limiting wheel bracket 906 is fixedly connected to the front end of the connecting plate 903, and the rear end of the connecting plate 903 is rotatably connected to the main frame rotating shaft 901. The inner end of the bracket rotating shaft 901 is rotatably connected to the cutting table frame 1, and the outer end of the bracket rotating shaft 901 is rotatably connected to the rear end of the connecting plate 903 through the bushing 902.

[0025] Meanwhile, the connecting plate 903 is connected to the cutting table frame 1 via a depth limiting cylinder 904. The top of the cylinder body of the depth limiting cylinder 904 is rotatably connected to the cutting table frame 1, and the bottom of the piston rod of the depth limiting cylinder 904 is rotatably connected to the connecting plate 903.

[0026] When the digging depth of the peanut digging mechanism 7 needs to be adjusted, the depth-limiting cylinder 904 is activated. The depth-limiting cylinder 904 drives the connecting plate 903 to rotate around the rotational connection point between the connecting plate and the support shaft. During the rotation of the connecting plate, the depth-limiting wheel 905 changes its vertical position through the depth-limiting wheel support 906. Under the support of the depth-limiting wheel 905, the height of the front end of the header frame 1 changes, which in turn changes the height of the peanut digging mechanism 7, thereby achieving the adjustment of the digging depth.

[0027] The clamping device 11 includes two opposing clamping chains 1101, which are wound around clamping sprockets 1102. As the clamping sprockets 1102 rotate, they drive the clamping chains 1101 to rotate. During this relative movement of the two clamping chains 1101, peanut vines are fed between them. Under the clamping and conveying action of the two clamping chains 1101, the peanut vines are transported from the front of the header frame to the rear of the header frame.

[0028] In this embodiment, a plurality of support bolts 1103 are provided inside the clamping chain on one side. The inner end of the support bolt 1103 is fixedly connected to the first guide rail, and the outer end of the support bolt 1103 is fixedly connected to the cutting table frame 1. The first guide rail generates an inward pushing force on the clamping chain. A plurality of support bolts 1103 are provided at intervals along the conveying direction of the clamping chain. The support bolts 1103 provide support and tightening for the clamping chain 1101 through the first guide rail.

[0029] On the other side, the clamping chain is equipped with several tensioning mechanisms at intervals. For example... Figure 8 As shown, the tensioning mechanism includes a tensioning shaft 603 and a fixed sleeve 605. The inner end of the tensioning shaft 603 is connected to the second guide rail 601 via a pin 602. The second guide rail exerts an inward pushing force on the clamping chain. The outer end of the tensioning shaft 603 is movably disposed within the fixed sleeve 605, which is fixedly connected to the cutting table frame 1. A compression spring 604 is wound around the annular outer side of the tensioning shaft 603.

[0030] The clamping chains on both sides, pushed by the first and second guide rails, exert a clamping force on the peanut vines that enter between the clamping chains. When too many peanut vines enter between the two clamping chains, the tensioning shaft 603 moves outward under the pushing force of the peanut vines, driving the second guide rail to move outward, thereby adjusting the distance between the two clamping chains and the clamping force accordingly, and generating a compression force in the compression spring 604. When the amount of peanut vines entering between the two clamping chains decreases, the second guide rail automatically resets under the elastic force of the compression spring 604, and the clamping chains on both sides return to their initial distance and clamping force.

[0031] During actual harvesting, the amount of peanut vines fed in is controlled by the walking speed. The clamping bolts and tensioning mechanism 6 in this application ensure that the clamping chains are always taut, and automatically adjust the distance between the two clamping chains and the clamping force based on the amount of peanut vines entering between them, thus enabling the header to be suitable for various walking speeds.

[0032] During the process of clamping and transporting the excavated peanut vines by the clamping mechanism, the soil is removed by the soil-vibrating swing mechanism and the peanuts are picked by the peanut-picking mechanism.

[0033] like Figure 5 As shown, the vibrating oscillation mechanism 2 includes a drive shaft 203, an eccentric shaft 204, symmetrically arranged hanging plates on both sides, and an oscillating rod 212 fixedly connected to the bottom of the scraper. The drive shaft 203 is located on the top of the cutting table frame 1 and is rotatably connected to the cutting table frame 1 via a bearing 202. One end of the drive shaft 203 is fixed with a drive sprocket 201, which transmits power to the drive shaft 203, enabling the drive shaft 203 to rotate. The other end of the drive shaft 203 is fixed with an eccentric shaft 204. The eccentric shaft 204 is connected to the first bearing sleeve 207 via a connecting rod 205 and a connecting handle 206. The upper end of the connecting rod 205 is eccentrically connected to the eccentric shaft 204, and the lower end of the connecting rod 205 is connected to the connecting handle 206. The bottom end of the connecting handle 206 is provided with the first bearing sleeve 207. During the rotation of the drive shaft 203, the connecting rod 205 moves up and down through the eccentric shaft 204, thereby realizing the reciprocating motion of the first bearing sleeve 207.

[0034] A set of hanging plates is provided on both sides along the conveying direction of the clamping chain. Each hanging plate includes at least one hanging plate arranged in the vertical direction, and the hanging plates on the same side are all fixed on the connecting shaft 210. The connecting shaft 210 is rotatably connected to the cutting table frame 1.

[0035] In this embodiment, each set of hanging plates includes two hanging plates, namely a first hanging plate 209 and a second hanging plate 213, which are symmetrically arranged on both sides. The tops of the first hanging plates on both sides are connected by a bearing sleeve connecting plate 214, and both first hanging plates are rotatably connected to the bearing sleeve connecting plate. The upper part of the first hanging plate 209 is rotatably connected to the connecting shaft 210, and the upper part of the first hanging plate 209 is fixedly connected to the second bearing sleeve 208. The second bearing sleeve 208 is located directly below the first bearing sleeve 207, and the first bearing sleeve 207 and the second bearing sleeve 208 are vertically fixedly connected by welding. The upper end of the second hanging plate 213 is fixedly connected to the connecting shaft 210, and the bottom of the first hanging plate 209 and the bottom of the second hanging plate 213 are connected by a swing rod 212.

[0036] During the rotation of the transmission rod 203, the first bearing sleeve 207 is driven to move up and down through the eccentric shaft 204 and the connecting rod 205. When the first bearing sleeve 207 moves downward, it will generate a downward thrust on the second bearing sleeve 208. At this time, the first hanging plate 209, which is fixedly connected to the second bearing sleeve 208, will rotate counterclockwise around the connecting shaft 210, thereby driving the swing rod 212 at the bottom of the first hanging plate 209 to swing.

[0037] During one revolution of the eccentric shaft 204, the bearing sleeve connecting plate 214 completes one cycle of clockwise and counterclockwise rotation. During continuous rotation of the eccentric shaft 204, the bearing sleeve connecting plate 214 achieves a reciprocating cycle of clockwise and counterclockwise rotation. When one side of the first hanging plate 209 rotates, the bearing sleeve connecting plate 214 at its top drives the other side's first hanging plate to rotate synchronously in the same direction. The swing rods fixed to the bottom of both first hanging plates also swing synchronously. During the reciprocating cycle of clockwise and counterclockwise rotation of the bearing sleeve connecting plate 214, the swing rods continuously swing to the left and right. Under the combined swinging action of the swing rods on both sides, the soil around the peanut vine roots is vibrated and removed.

[0038] When the peanut vines, after being initially vibrated to remove the soil, are clamped and transported into the peanut picking mechanism 4, the peanut pods are picked.

[0039] like Figure 6 and Figure 7 As shown, the peanut picking mechanism includes a first roller 407 and a second roller 412. The first roller 407 and the second roller 412 rotate in opposite directions and have the same rotation speed. Both the first roller 407 and the second roller 412 are equipped with picking plates 409. Under the combined action of the picking plates on both sides of the rollers, the peanut fruits at the root of the peanut vine can be picked.

[0040] In this embodiment, the peanut picking mechanism also includes a first drive shaft 401. A main drive sprocket 405 is fixed at the end of the first drive shaft 401. Power is transmitted to the first drive shaft 401 through the main drive sprocket 405, thereby realizing the rotation of the first drive shaft 401. The first rotating shaft 401 is rotatably connected to the cutting frame 1 through the first bearing seat 404.

[0041] The first drive shaft 401 transmits torque to the first roller and the second roller via bevel gear sets. In this embodiment, a first bevel gear 402 is fixed on the first drive shaft 401, and a second bevel gear 403 is fixed to the end of the first main shaft 411 of the first roller 407. The first bevel gear 402 and the second bevel gear 403 mesh with each other. During the rotation of the first bevel gear 402 driven by the first drive shaft 401, the meshing between the first bevel gear 402 and the second bevel gear 403 drives the first main shaft 411 and the first roller 407 fixed on the first main shaft 411 to rotate. Similarly, the first drive shaft 401 transmits torque to the second roller 412 via the bevel gear set.

[0042] In this embodiment, the first roller and the second roller have the same structure, so the structure of the roller is described in detail using the first roller as an example. The two ends of the first roller 407 are respectively provided with a second bearing seat 406 and a third bearing seat 410, and the rotational connection between the first roller 407 and the cutting table frame 1 is realized through the second bearing seat 406 and the third bearing seat 410.

[0043] The annular outer surface of the first roller is provided with several fruit-picking plates 409 extending axially, which are spaced apart along the circumference of the first roller 407. In this embodiment, the fruit-picking plates 409 are fixed to the outer surface of the first roller by plate bases 408.

[0044] The first roller 407 and the second roller 412 rotate inward simultaneously. During the rotation, the picking plates on both rollers exert a downward drag force on the peanuts at the base of the peanut vine, pulling the peanuts off the base of the peanut vine, thus completing the picking action.

[0045] After the peanut vines are picked, they are held and transported to the rear of the cutting platform by the clamping mechanism. In order to facilitate the collection of the peanut vines, the tensioning and guiding mechanism 13 is used to turn and throw the peanut vines.

[0046] like Figure 2 As shown, the tensioning and guiding mechanism 13 includes a guiding chain 1303, a tensioning plate 1301 on one side of the guiding chain 1303, and guiding teeth 1302 at the rear end of the guiding chain 1303. When the peanut vine moves to the rear end of the clamping mechanism and disengages from it, the guiding chain 1303 and the tensioning plate 1301 continue to guide and transport the peanut vine. When the peanut vine is conveyed to the rear of the guiding chain 1303, the guiding teeth 1302 act as a deflector. After the peanut vine leaves the tensioning and guiding mechanism 13, it will complete a throwing action under its own gravity, thereby turning and throwing the peanut vine to the designated position.

[0047] The height of the cutting table is adjusted via the cutting table lifting mechanism 5. For example... Figure 9As shown, the header lifting mechanism 5 includes a lifting cylinder 502. The bottom of the cylinder body of the lifting cylinder 502 is rotatably connected to the walking device that realizes the movement of the peanut harvester. The top of the piston rod of the lifting cylinder 502 is rotatably connected to the lifting cylinder bracket 501. The lifting cylinder bracket 501 is fixed on the side of the header frame 1.

[0048] This header frame is typically used in conjunction with the peanut harvester. When the peanut harvester is not in operation or is turning, because the header is shaped with a lower front and a higher rear, in order to prevent the header from contacting or colliding with the ground and causing damage, the lifting cylinder 502 is activated to raise the height of the entire header, so that the front end of the header is away from the ground, effectively avoiding contact between the front end of the header and the ground and thus preventing damage to the header.

[0049] The power transmission mechanism used in this application is described below. Power transmission mechanisms are provided on both sides of the header frame. The output shaft of the peanut harvester's gearbox is connected to pulley 301 via belt drive. The pulley shaft in the middle of pulley 301 is fixedly connected to the right side of the header frame. Pulley 301 is sequentially connected to the intermediate drive shaft 305 located at the rear end of the header via a first right drive chain 302 and a second right drive chain 303. Both ends of the intermediate drive shaft 305 are respectively connected to the side drive shafts 304 located on both sides via bevel gear sets. The side drive shafts on both sides are fixedly connected to the drive sprockets of the clamping chains on both sides. The power output from the gearbox is sequentially transmitted to the clamping mechanism via belt drive, chain drive, and bevel gear drive, realizing the transmission of the clamping chains on both sides.

[0050] Simultaneously, the power output from the gearbox is sequentially transmitted to the peanut harvesting mechanism via the left first main drive chain 306, left second drive chain 307, and left third drive chain 308. The left third drive chain 308 is wound around the main drive sprocket 405, realizing the harvesting action of the peanuts. The power output from the gearbox is sequentially transmitted to the soil-vibrating swing mechanism 2 via the left first main drive chain 306, left second drive chain 307, left third drive chain 308, and left fourth drive chain 309. The left fourth drive chain 309 is wound around the driving sprocket 201, realizing the vibration and soil removal of the peanut vine roots. The sprocket shaft of the driven sprocket of the left first main drive chain 306 is fixedly connected to the left side of the header frame.

[0051] The other end of the belt wound on pulley 301 is equipped with a drive pulley, which is mounted on the swaying screen stand on one side of the peanut harvester; the drive sprocket of the first main drive chain 306 on the left side is mounted on the swaying screen stand on the other side of the peanut harvester. The pulley shaft of pulley 301 and the sprocket shaft of the driven sprocket of the first main drive chain 306 on the left side provide support for the header frame.

[0052] The working principle of the peanut harvesting header is as follows. The entire header is shaped with a lower front and a higher rear. Therefore, as the header moves forward with the peanut harvester, the foremost peanut digging mechanism inserts into the roots of the peanut vines to dig them out of the soil. Subsequently, the vine straightener 8 helps the peanut vines neatly and smoothly enter between the two clamping chains of the clamping mechanism. As the clamping chains clamp and transport the peanut vines, they are gradually conveyed from the front to the rear of the header. During this transport process, the soil is removed by the vibration of the soil-vibrating mechanism, and the peanut harvesting mechanism harvests the peanuts in sequence.

[0053] After the peanut vines are picked, they leave the clamping mechanism and are then transported to a designated location by the tensioning and guiding mechanism to facilitate the subsequent collection of the peanut vines.

[0054] This application also discloses a peanut harvester including the aforementioned excavating, vibrating, and harvesting platform. For example... Figure 10 As shown, the peanut harvester also includes a vibrating screening and cleaning device 15, a tracked walking device 16, a chassis 17, a conveying device 18, a fruit collection box 19, and a driver's cab 20. The digging, vibrating, and picking cutting platform 14 is located at the front of the peanut harvester, and the tracked walking devices 16 are respectively provided on both sides of the bottom of the peanut harvester, enabling the harvester to move.

[0055] Below the excavating and harvesting platform 14, a vibrating screening and cleaning device 15 is installed. Peanuts harvested by the peanut harvesting mechanism fall into the vibrating screening and cleaning device 15, where weeds, peanut vines, and other debris are removed by air separation. Simultaneously, a vibrating screen further removes soil from the peanuts. Behind the vibrating screening and cleaning device 15, a conveying device 18 is installed, transporting the vibrated and cleaned peanuts to a collection box 19. The excavating and harvesting platform 14, the vibrating screening and cleaning device 15, and the conveying device 18 are all mounted on the chassis 17.

[0056] A driver's cab 20 is located on one side of the excavating and harvesting platform 14, and a peanut collection box 19 is located behind the driver's cab 20. The peanuts discharged from the vibrating screening and cleaning device 15 are conveyed to the bottom of the peanut collection box 19 by the conveyor chain of the conveyor device, and then conveyed into the peanut collection box 19 by the inclined conveyor and scraper.

[0057] In this embodiment, the vibration screening and cleaning device 15, the tracked walking device 16, the chassis 17, the conveying device 18, and the fruit collection box 19 all adopt existing mature technologies, so they will not be described in detail here.

[0058] During the operation of the peanut harvester, the driver, located in the cab 20, controls the operating mechanism to control the direction of movement, the raising and lowering of the header, and the raising and lowering of the depth-limiting wheels. As the peanut harvester moves forward, the digging, vibrating, and picking header 14 digs, removes soil, and picks the peanut vines and pods. The picked peanut vines are then thrown to a designated location behind the harvester. The picked peanuts fall onto the vibrating screening and cleaning device 15 for cleaning and further soil removal, and are finally transported to the collection box 19 via the conveying device 18, thus collecting the peanuts.

[0059] In the lifting mechanism of the excavating, vibrating, and fruit-picking cutting platform 14, the bottom of the lifting cylinder 502 is connected to the track frame of the track walking device 16.
