Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and more specifically, to a horizontal header for a multi-terrain corn harvester. Background Technology

[0002] The horizontal header for multi-terrain corn harvesters is a core component for combine harvesters, plant protection machines, and other agricultural machinery to achieve low grounding voltage, high traction, and good passability in complex scenarios such as wetlands, hills, and conservation tillage.

[0003] A search revealed that CN 217826000 U discloses a four-row corn harvester that harvests both ears and stalks, and its header. The harvester includes four feeding mechanisms and two horizontally positioned ear-picking and stalk-pulling devices mounted on the header frame. The two horizontally positioned ear-picking and stalk-pulling devices correspond to the two feeding mechanisms and are arranged horizontally in a straight line. Each ear-picking and stalk-pulling device includes an ear-picking device and a stalk-pulling device. The ear-picking device includes an upper ear-picking roller and a lower ear-picking device. The upper ear-picking roller has an ear-picking spiral structure, and the space between the lower end of the upper ear-picking roller and the lower ear-picking device is the front stalk passage area. The stalk-pulling device includes an upper stalk-pulling roller and a lower stalk-pulling roller. The lower stalk-pulling roller includes a stalk conveying part and a clearance part. The gap between the clearance part and the upper stalk-pulling roller is the rear stalk passage area. The feeding mechanism includes a feeding chain and an auxiliary chain. The feeding chain passes through the front and rear stalk passage areas and extends to the rear of the stalk-pulling device.

[0004] In actual use, the aforementioned patent has several drawbacks. During the harvesting process, the cutting part of the machine head cuts the corn stalks as the vehicle moves forward. As the corn stalks change from an upright to a tilted position and enter the harvesting spiral structure, the tilting direction is inconsistent due to the stalks tilting under their own weight. This uneven delivery of the stalks can easily cause them to become congested between the harvesting and harvesting spiral structures, leading to harvesting blockages. Therefore, this invention discloses a horizontal header for a multi-terrain corn harvester. Summary of the Invention

[0005] To address the problem mentioned in the background art, existing horizontal headers, during the corn stalk posture conversion process, cause inconsistent stalk tilting directions due to their own weight, resulting in stalks being delivered in different postures. This can easily lead to corn stalks clogging between the harvesting structure and the ear-picking spiral structure, causing harvesting blockage.

[0006] This invention provides a horizontal header for a multi-terrain corn harvester, including a frame and a clearing structure; a picking spiral structure is installed above the frame, a guide plate is installed above the picking spiral structure, and a clearing structure is assembled on the guide plate; the clearing structure is used to lift and pull the corn stalks, and to drag and transport the cut corn stalks.

[0007] The unblocking structure includes a bidirectional motor, which is installed on the top side of the guide plate. The two output ends of the bidirectional motor are respectively equipped with motor shafts, and drive disks are respectively installed on the two motor shafts. A push rod is rotatably connected to the end face of the drive disk at an eccentric position. A sliding rod hole is opened in the middle of the push rod.

[0008] It also includes a fixing frame, in which a limiting rod is installed laterally, and the two ends of the limiting rod pass through the sliding rod holes in the push rods on both sides respectively;

[0009] The other end of the push link is provided with a mounting groove, in which a swing wheel is rotatably mounted, and a push hook is fixed on the circumferential surface of the swing wheel;

[0010] The other end of the push link is fixed with a limit frame, and a limit pin is assembled inside the limit frame. The limit pin is used to limit the swing of the push hook.

[0011] As a further improvement to this technical solution, limit caps are fixed at both ends of the limiting rod, and the diameter of the limit caps is larger than the width of the sliding rod hole. During the movement of the push link, the limit caps can be used to slide and limit the push link, ensuring the sliding state of the limit rod inside the sliding rod hole, ensuring the stability of the rotation state of the push link, and enabling the limit rod to play a sliding support role for the push link.

[0012] As a further improvement to this technical solution, a connecting rod is fixed to the top side of the other end of the push rod, and an arc-shaped push plate is connected to the connecting rod.

[0013] As a further improvement to this technical solution, a harvesting structure is installed on the frame. The harvesting structure includes a first harvesting plate and two second harvesting plates. The first and second harvesting plates are both fixed on a crossbeam on one side of the frame. The two second harvesting plates are respectively fixed on both sides of the first harvesting plate. One side of the first harvesting plate and the adjacent side of the second harvesting plate form a V-shaped opening.

[0014] As a further improvement to this technical solution, two driven gears and two driving gears are respectively installed on the top side of the first harvesting plate via a rotating shaft. A harvesting chain is fitted on the driven gear and driving gear on the same side, and harvesting knives are intermittently mounted on the harvesting chain. A driven gear and a driving gear are respectively installed on the top side of the second harvesting plate via a rotating shaft. A harvesting chain is fitted on the driven gear and driving gear, and harvesting knives are intermittently mounted on the harvesting chain. Liquid pump motors are mounted on the bottom sides of both sides of the first harvesting plate, and liquid pump motors are respectively mounted on the bottom sides of the two second harvesting plates. The output shaft of each liquid pump motor is connected to the rotating shaft of the corresponding driving gear. A central protective cover is mounted above the first harvesting plate, and a side protective cover is mounted above the second harvesting plate.

[0015] As a further improvement to this technical solution, a feeding space is formed between the side protective cover and the central protective cover. The push hook and arc-shaped push plate in the unblocking structure act within the feeding space between the side protective cover and the central protective cover, and the fixing frame in the unblocking structure is fixed at the top center of the central protective cover.

[0016] As a further improvement to this technical solution, a picking spiral structure is installed on the top side of the frame. The picking spiral structure includes a feeding box, which is installed in the middle of the top side of the frame. A rotating shaft is installed laterally inside the feeding box. A first thread cutter and a second thread cutter are respectively installed on the outer ends of the rotating shaft. The first thread cutter and the second thread cutter are assembled in opposite spiral directions. The first thread cutter and the second thread cutter are located inside the feeding box. A crushing gear is keyed to one end of the rotating shaft. The crushing gear is located on the outer side of the feeding box.

[0017] As a further improvement to this technical solution, a guide port is provided in the middle of the feeding box, and a feeding pipe is connected to the guide port. The feeding pipe is used to guide and transport the crushed corn stalks through the ear-picking spiral structure.

[0018] As a further improvement to this technical solution, a stubble-removing structure is installed on another crossbeam of the frame. The stubble-removing structure includes a support frame, a cutter shaft is rotatably mounted inside the support frame, a crushing roller is mounted in the middle of the cutter shaft, a stubble-removing blade is mounted on the crushing roller, and a stubble-removing gear is mounted at one end of the cutter shaft.

[0019] As a further improvement to this technical solution, a guide plate is installed on the opening of the feeding box. The curved surface of the guide plate is set in the feeding space between the side protective cover and the central protective cover. Connecting ears for connecting the whole machine are installed at both ends of the outer side of the feeding box. An installation cover is installed on the top of the guide plate to realize the driving protection of the bidirectional motor.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] This multi-terrain corn harvester uses a horizontal cutting platform. A bidirectional motor synchronously drives the push hooks on both sides, creating a two-stage reciprocating motion of traction and avoidance. Combined with the forced orientation of the straw by the arc-shaped push plate, the straw maintains an orderly flow between the harvesting and crushing structures. This overcomes the cantilever jamming phenomenon caused by random straw tilting, effectively clearing and delivering corn straw, preventing straw accumulation and blockage. High-speed continuous feeding is achieved. The closed guide channel formed by the central and side protective covers, in conjunction with the figure-eight shaped harvesting opening, constructs a forced feeding space. Combined with the active hooking of the push hooks, this prevents the escape of cut corn straw, ensuring effective clearing of the corn straw and stable delivery within the conveying channel.

[0022] By ensuring the stable delivery of corn stalks in the conveyor channel, this method can better facilitate the harvesting and delivery of corn stalks in complex terrains such as hills and mountains, where the stalks, after being cut, tend to tilt in different directions due to their own weight.

Detailed Implementation

[0034] 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.

[0035] Therefore, such as Figure 1 , Figure 2 As shown, the present invention provides a horizontal header for a multi-terrain corn harvester, including a frame 1 and a clearing structure 6. A picking spiral structure 3 is installed above the frame 1, and a guide plate 5 is installed above the picking spiral structure 3. The clearing structure 6 is mounted on the guide plate 5. The clearing structure 6 is used to lift and pull the corn stalks, and to drag and transport the cut corn stalks.

[0036] like Figure 4 , Figure 5 As shown, the unblocking structure 6 includes a bidirectional motor 602, which is installed on the top side of the guide plate 5. The two output ends of the bidirectional motor 602 are respectively equipped with motor shafts 603, and drive disks 604 are respectively installed on the two motor shafts 603. The end face of the drive disk 604 is eccentrically connected to a push rod 606, and a sliding rod hole 607 is opened in the middle of the push rod 606.

[0037] It also includes a fixing frame 605, in which a limiting rod 609 is installed laterally, and the two ends of the limiting rod 609 pass through the sliding rod hole 607 in the push connecting rods 606 on both sides respectively;

[0038] The other end of the push link 606 is provided with a mounting groove 612, and a swing wheel 615 is rotatably mounted in the mounting groove 612. A push hook 610 is fixed on the circumferential surface of the swing wheel 615.

[0039] like Figure 5 As shown, a limit frame 613 is fixed to the bottom side of the other end of the push link 606. A limit pin 614 is assembled inside the limit frame 613. The limit pin 614 is used to limit the swing of the push hook 610.

[0040] During operation, when cutting upright corn stalks, the corn stalks are cut and transported as the harvesting vehicle moves forward. As the corn stalks change from an upright posture to a tilted posture and enter the ear-picking spiral structure 3, the tilting process is determined by the corn stalks' own offset, which can cause the corn stalks to become congested between the harvesting structure 2 and the ear-picking spiral structure 3, easily causing harvesting blockage.

[0041] To clear the feeding area, the bidirectional motor 602 drives the motor shafts 603 on both sides to rotate, thereby achieving synchronous rotation of the drive discs 604 on both sides, which in turn enables the operation of the push rods 606 on both sides. The movement process of the push rods 606 is divided into two stages.

[0042] The first stage is the traction process: When the harvested corn stalks are conveyed from the harvesting structure 2 to the ear-picking spiral structure 3, the movement trajectory of one end of the push rod 606 is pulled by the drive disc 604, moving along the upper half of the rotating drive disc 604. During the traction process, as one end of the push rod 606 is gradually lifted and pulled, the push rod 606 moves closer to the ear-picking spiral structure 3. During the sliding movement of the push rod 606, the limiting rod 609 slides relative to the sliding rod hole 607, while the other end of the push rod 606 is in a downward swinging state. During the traction movement of the push rod 606, the bottom push hook 610 is used to hook and pull the fallen stalks, pulling the corn stalks from the harvesting structure 2 to the ear-picking spiral structure 3.

[0043] The limiting pin 614 is set on the bottom side of the push hook 610, which can limit the swing angle between the push link 606 and the push hook 610, prevent the push hook 610 from swinging excessively, and ensure that the hooking area at the bottom of the push hook 610 can act on the straw part.

[0044] The second stage is the pushing stage: After the hooking and traction conveying, the push hook 610 needs to return to its starting position; during the return movement of the push hook 610, its direction of movement is from the ear-picking spiral structure 3 to the harvesting structure 2; during the pushing movement, one end of the push link 606 moves along the lower half of the rotating drive disc 604. During the pushing process, the push hook 610 is squeezed by the straw behind it, causing the bottom of the push hook 610 to swing up and slide backward. During the sliding movement of the push link 606, the other end of the push link 606 is in an upward movement state, pushing the push hook 610 to a position away from the ear-picking spiral structure 3, so that the push hook 610 can achieve the hooking and traction movement of corn straw in subsequent traction operations.

[0045] Through reciprocating linkage and traction, the cut and dumped corn stalks can be continuously moved and transported from the harvesting structure 2 to the ear-picking spiral structure 3, avoiding the accumulation and blockage of stalks and improving harvesting efficiency.

[0046] like Figure 4 As shown, both ends of the limiting rod 609 are fixed with limiting caps 608, and the diameter of the limiting caps 608 is larger than the width of the sliding rod hole 607. During operation, the limiting caps 608 can slide and limit the pushing rod 606 during its movement, ensuring the sliding state of the limiting rod 609 inside the sliding rod hole 607, ensuring the stability of the rotation state of the pushing rod 606, and enabling the limiting rod 609 to play a sliding support role for the pushing rod 606.

[0047] like Figure 5 As shown, a connecting rod 616 is fixed to the top side of the other end of the push rod 606, and an arc-shaped push plate 611 is connected to the connecting rod 616;

[0048] During operation, during the pushing phase, when the push link 606 returns, the arc-shaped push plate 611 can move synchronously under the synchronous linkage of the connecting rod 616. During the pushing operation of the arc-shaped push plate 611, the corn stalks cut from the bottom can be pushed down in one direction, so that the direction of the corn stalks is tilted along the direction of vehicle movement, so as to better cooperate with the hooking and traction of the push hook 610 for conveying operations.

[0049] A harvesting structure 2 is installed on the frame 1. The harvesting structure 2 includes a first harvesting plate 201 and two second harvesting plates 202. The first harvesting plate 201 and the second harvesting plate 202 are both fixed on a crossbeam on one side of the frame 1. The two second harvesting plates 202 are respectively fixed on both sides of the first harvesting plate 201. One side of the first harvesting plate 201 and the adjacent side of the second harvesting plate 202 form a V-shaped opening.

[0050] During operation, while cutting the standing corn stalks, the harvester moves forward and harvests along the corn planting path. During the harvesting process, the two sides of the first harvesting plate 201 and the two sides of the second harvesting plates 202 form a figure-eight shaped harvesting opening. The figure-eight shaped harvesting opening moves along the corn planting path to harvest the corn.

[0051] like Figure 6 , Figure 7 As shown, the top side of the first harvesting plate 201 has two driven gears 207 and two drive gears 204 mounted on it via a rotating shaft. A harvesting chain 205 is fitted onto the driven gears 207 and drive gears 204 on the same side. Harvesting blades 206 are intermittently mounted on the harvesting chain 205. Similarly, the top side of the second harvesting plate 202 has driven gears 207 and drive gears 204 mounted on it via a rotating shaft. A harvesting chain 205 is fitted onto the driven gears 207 and drive gears 204. Harvesting blades 206 are intermittently mounted on the harvesting chain 205. Hydraulic pump motors 208 are mounted on the bottom sides of both sides of the first harvesting plate 201. Hydraulic pump motors 208 are also mounted on the bottom sides of the two second harvesting plates 202. The output shaft of each hydraulic pump motor 208 is connected to the rotating shaft of the corresponding drive gear 204. Figure 3 As shown, a central protective cover 209 is mounted above the first harvesting plate 201, and a side protective cover 210 is mounted above the second harvesting plate 202.

[0052] During operation, the main harvester pumps oil to deliver driving force to each hydraulic pump motor 208. The hydraulic pump motor 208 drives the matched drive gear 204. With the cooperation of the driven gear 207, the harvesting chain 205 can be driven, which in turn drives the harvesting blade 206 to cut the corn stalks.

[0053] The harvesting chains 205 on both sides of the two figure-eight shaped harvesting openings rotate in opposite directions. With the rotation of the harvesting chains 205 on both sides of the figure-eight shaped harvesting openings, the harvesting blades 206 can cut the straw. At the same time, the cut straw is pre-conveyed at the bottom to achieve the effect of harvesting and conveying.

[0054] like Figure 3 As shown, a feeding space is formed between the side protective cover 210 and the central protective cover 209. The push hook 610 and the arc-shaped push plate 611 in the unblocking structure 6 act in the feeding space between the side protective cover 210 and the central protective cover 209, and the fixing bracket 605 in the unblocking structure 6 is fixed at the top middle position of the central protective cover 209.

[0055] During operation, the stalks are cut by the cooperation of the harvesting chain 205 and the harvesting blade 206 in the harvesting structure 2 during the corn harvesting process. A central protective cover 209 is installed on the first harvesting plate 201, and a side protective cover 210 is installed on the second harvesting plate 202. First, the central protective cover 209 and the side protective cover 210 can protect the internal transmission structure. Second, through their own protrusions, they can provide a good guiding effect on the cut corn stalks and better guide the cutting and conveying of the stalks.

[0056] During the conveying of straw, by forming a feeding space between the central protective cover 209 and the side protective cover 210, the cut straw can be better constrained and delivered, so as to achieve the effect of clearing the feeding channel by traction hooking operation with the push hook 610.

[0057] like Figure 8 As shown, a picking spiral structure 3 is installed on the top side of the frame 1. The picking spiral structure 3 includes a feeding box 301, which is installed in the middle of the top side of the frame 1. A rotating shaft 303 is rotatably mounted inside the feeding box 301. A first thread cutter 302 and a second thread cutter 304 are respectively installed on the outer sides of the two ends of the rotating shaft 303. The assembly spiral directions of the first thread cutter 302 and the second thread cutter 304 are opposite. The first thread cutter 302 and the second thread cutter 304 are located inside the feeding box 301. A crushing gear 305 is keyed to one end of the rotating shaft 303. The crushing gear 305 is located on the outer side of the feeding box 301.

[0058] During operation, when conveying the cut and dumped corn stalks, the dredging structure 6 conveys the stalks from the harvesting structure 2 to the ear-picking spiral structure 3. During the conveying of the corn stalks, the vehicle engine drives the transmission chain to drive the crushing gear 305. Driven by the crushing gear 305, the rotating shaft 303 rotates. During the rotation of the rotating shaft 303, the first threaded blade 302 and the second threaded blade 304 at both ends can work synchronously. During the rotation of the first threaded blade 302 and the second threaded blade 304, the spiral feeding capacity of the first threaded blade 302 and the second threaded blade 304 is used to crush the long strips of corn stalks during the conveying process. The corn stalks crushed by the first threaded blade 302 and the second threaded blade 304 are conveyed to the middle and discharged through the feeding pipe 7. Then, through subsequent whole-machine crushing and screening, the corn is harvested.

[0059] like Figure 8 As shown, a guide port is provided in the middle of the feeding box 301, and a feeding pipe 7 is connected to the guide port. During operation, the feeding pipe 7 is used to guide and transport corn stalks through the ear-picking spiral structure 3.

[0060] like Figure 9 As shown, a stubble-removing structure 4 is installed on another crossbeam of the frame 1. The stubble-removing structure 4 includes a support frame 401. A cutter shaft 402 is rotatably mounted inside the support frame 401. A crushing roller 404 is mounted in the middle of the cutter shaft 402. A stubble-removing blade 405 is mounted on the crushing roller 404. A stubble-removing gear 403 is mounted at one end of the cutter shaft 402.

[0061] During operation, the vehicle engine drives the transmission chain to drive the stubble-crushing gear 403, which in turn drives the cutter shaft 402 to rotate, thereby rotating the crushing roller 404. With the cooperation of the stubble-crushing blade 405, the corn stubble can be crushed, thus achieving stubble-crushing operation after corn harvesting.

[0062] like Figure 3 As shown, a guide plate 5 is installed on the opening of the feeding box 301. The curved surface of the guide plate 5 is set in the feeding space between the side protective cover 210 and the central protective cover 209. An installation cover 601 is installed above the guide plate 5 to realize the driving protection of the bidirectional motor 602.

[0063] like Figure 8 As shown, the outer ends of the feeding box 301 are respectively equipped with connecting ears 8 for connecting to the whole machine.

[0064] During operation, when the cut corn stalks are conveyed from the harvesting structure 2 to the ear-picking spiral structure 3 via the unblocking structure 6, the cut ends of the corn stalks first enter the feeding box 301. In the conventional stalk conveying process, the stalks are piled up and conveyed in a disorderly manner into the feeding box 301 for spiral conveying. By setting the push hook 610, the corn stalks can be tilted in one direction. At the same time, with the hooking and traction conveying of the push hook 610, the cut ends of the stalks can enter the feeding box 301 first, so that they can be conveyed by the spiral conveying of the first threaded blade 302 and the second threaded blade 304. With the guidance of the guide plate 5, it is easy for the cut ends of the stalks to bend and enter, preventing the stalks from escaping and avoiding the accumulation of stalks in the conveying path, so as to achieve a better harvesting effect.
