Description

Technical Field

[0001] This utility model relates to the field of harvester header technology, specifically a harvester header chassis that can adapt to terrain. Background Technology

[0002] The header chassis of a harvester is the core support structure connecting the header to the main frame of the harvester. It is not only the "skeleton" of the header, but also the "central hub" for its power transmission and lifting adjustment.

[0003] Most existing harvester chassis adopt a rigid connection structure with a fixed ground clearance, lacking an effective buffer and adaptive adjustment mechanism. When encountering uneven terrain, the whole machine is prone to severe vibration or even jamming, which not only leads to uneven harvesting depth, crop omissions or damage, but also causes rigid impact on key components such as the header and blades, accelerating their wear and fatigue. In addition, the sliding friction between the chassis and the ground further increases the movement resistance and power consumption, limiting the harvester's passability and operating efficiency in complex fields. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a harvester header chassis that can adapt to terrain, solving the problem that most existing harvester header chassis adopt a rigid connection structure with a fixed ground clearance and lack an effective buffer and adaptive adjustment mechanism.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a harvester header chassis that can adapt to terrain, including a vehicle body, a header inserted through the bottom of the vehicle body, a chassis detachably connected to the outer side wall of the header, one end of the chassis inserted through the bottom of the vehicle body, and a harvesting component detachably connected inside the header. The chassis includes multiple elastic elements, each of which is detachably connected to the outer wall of the cutting platform. The top of each elastic element is fixedly connected to the bottom of the vehicle body. A housing is fixedly connected to the side of the elastic element away from the cutting platform, and multiple rollers are detachably connected to the outer wall of the housing.

[0006] Preferably, the elastic element includes a mounting plate, which is detachably connected to the outer wall of the cutting table. A telescopic column is fixedly connected to the lower end face of the top wall of the mounting plate, and a receiving plate is fixedly connected to the bottom end of the telescopic column. The receiving plate is fixedly connected to the upper end face of the outer shell.

[0007] Preferably, the telescopic column includes a plug-in rod, which is fixedly connected to the lower end face of the mounting plate. A sleeve is slidably connected to the outer wall of the plug-in rod. The bottom end of the sleeve is fixedly connected to the upper end face of the receiving plate. A spring is nested in the outer wall of the sleeve. The top end of the spring is fixedly connected to the lower end face of the mounting plate, and the bottom end of the spring is fixedly connected to the upper end face of the receiving plate.

[0008] Preferably, the roller includes a limiting frame, an installation block is detachably connected inside the limiting frame, a limiting rod passes through the side wall of the limiting frame, the limiting rod passes through the installation block, and a roller is rotatably connected to the installation block near its bottom end.

[0009] Preferably, the bottom wall of the receiving plate is detachably connected with a plurality of bolts, which are inserted into the side wall of the outer casing and are threadedly connected to the outer casing.

[0010] Preferably, the plurality of rollers are respectively disposed opposite to each other on both sides of the housing, and the plurality of rollers are arranged in a linear array.

[0011] Preferably, a connecting plate is fixedly connected to the upper surface of the plurality of mounting plates, and the plurality of connecting plates are fixedly connected to the bottom of the vehicle body.

[0012] Compared with the prior art, this utility model provides a harvester header chassis that can adapt to terrain, which has the following beneficial effects: Through the cooperation of elastic elements and rollers, when the equipment encounters steep slopes or mounds of earth, the rollers can move the outer shell up and down along the terrain undulations and compress the elastic elements; when the ground returns to flat, the elastic potential energy of the elastic elements pushes the outer shell back to its original position, so that the rollers always keep in contact with the ground, realizing the automatic adjustment of the cutting platform height, avoiding the problem of unstable harvesting depth or component jamming caused by uneven terrain, and improving the adaptability and stability of harvesting operations. The rollers adopt a drum structure and are rotatably connected to the mounting block through a rotating shaft. This converts the sliding friction between the chassis and the ground into rolling friction, which significantly reduces movement resistance and wear on the chassis and the ground. At the same time, the cushioning effect of the elastic element reduces the direct transmission of terrain impacts to the header and harvesting components, reduces the risk of mechanical fatigue, and thus extends the service life of key components.

Detailed Implementation

[0015] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0016] This utility model provides a technical solution: Please see Figures 1-4 The terrain-adaptive harvester header chassis includes a vehicle body 1, a header 2 inserted at the bottom of the vehicle body 1, a chassis detachably connected to the outer wall of the header 2, one end of the chassis inserted into the bottom of the vehicle body 1, and a harvesting component detachably connected inside the header 2. The harvesting component is the method of harvesting by rotating the harvesting blades with a motor, which is the existing technology used by most existing harvesters. Therefore, it has not been described in detail. The chassis includes multiple elastic elements 3, all of which are detachably connected to the outer wall of the cutting platform 2. The top of the elastic element 3 is fixedly connected to the bottom of the vehicle body 1. The side of the elastic element 3 away from the cutting platform 2 is fixedly connected to a housing 4. Multiple rollers 5 are detachably connected to the outer wall of the housing 4. It should be noted that during the harvesting process, since the roller 5 is in contact with the ground and is detachably connected to the outer wall of the outer shell 4, when encountering a steep slope or mound, the roller 5 will rise along the slope or mound, thereby driving the outer shell 4 to rise and squeezing the elastic element 3, causing the elastic element 3 to be compressed. When the roller 5 returns to the flat ground, the elastic potential energy of the elastic element 3 will exert a downward force on the outer shell 4, thereby causing the roller 5 to contact the ground, thus raising or lowering the cutting platform 2, thereby achieving the purpose of adaptive adjustment according to the terrain.

[0017] The elastic element 3 includes a mounting plate 31, which is detachably connected to the outer wall of the cutting table 2. A telescopic column 32 is fixedly connected to the lower end of the top wall of the mounting plate 31, and a support plate 33 is fixedly connected to the bottom end of the telescopic column 32. The support plate 33 is fixedly connected to the upper end of the outer shell 4. It should be noted that the telescopic column 32 includes a plug rod 321, which is fixedly connected to the lower end face of the mounting plate 31. A sleeve 322 is slidably connected to the outer wall of the plug rod 321. The bottom end of the sleeve 322 is fixedly connected to the upper end face of the receiving plate 33. A spring 323 is nested in the outer wall of the sleeve 322. The top end of the spring 323 is fixedly connected to the lower end face of the mounting plate 31, and the bottom end of the spring 323 is fixedly connected to the upper end face of the receiving plate 33. When the outer shell 4 is subjected to an upward force applied by the roller 5, the roller 5 applies a force to the receiving plate 33, and the receiving plate 33 applies a force to the sleeve 322 and the spring 323. Under the guidance of the sleeve 322 and the plug rod 321, the spring 323 contracts. When the force is lost, the outer shell 4 will return to its original position under the action of the spring 323, thereby achieving the effect of adaptive adjustment according to the terrain.

[0018] The roller 5 includes a limiting frame 51, a mounting block 52 is detachably connected inside the limiting frame 51, a limiting rod 53 passes through the side wall of the limiting frame 51, the limiting rod 53 passes through the mounting block 52, and a roller 54 is rotatably connected to the mounting block 52 near its bottom end. It should be noted that the top of the mounting block 52 is rectangular, and the bottom of the mounting block 52 has a mounting groove 56. A rotating shaft 55 is inserted through the side wall of the mounting groove 56, and the roller 54 is nested in the outer side wall of the rotating shaft 55, so that the roller 54 can rotate when it comes into contact with the ground. This converts the sliding friction between the bottom wall of the outer shell 4 and the ground into the rolling friction between the roller 54 and the ground, thereby avoiding damage to the roller 54 and the bottom wall of the outer shell 4 and extending the service life of the equipment.

[0019] The bottom wall of the receiving plate 33 is detachably connected with multiple bolts 6, which are inserted into the side wall of the outer shell 4 and are threadedly connected to the outer shell 4.

[0020] Multiple rollers 5 are respectively arranged opposite each other on both sides of the housing 4, and the multiple rollers 5 are arranged in a linear array.

[0021] Multiple mounting plates 31 are fixedly connected to the upper surface of the connecting plates 7. The multiple connecting plates 7 are all fixedly connected to the bottom of the vehicle body 1. A fixing plate 8 is welded between two connecting plates. The fixing plate 8 supports the transport pipeline of the cutting table 2.

[0022] In practical use, the working principle of this utility model is as follows: During harvesting, the vehicle body 1 moves the header 2 and chassis. When the crops to be harvested are below the chassis and header 2, the header 2 harvests the crops. When encountering steep slopes or mounds, the rollers 5 rise along the slopes or mounds. The rollers 5 apply force to the receiving plate 33, which in turn applies force to the sleeve 322 and the spring 323. Under the guidance of the sleeve 322 and the connecting rod 321, the spring 323 contracts. When the force is lost, the outer shell 4 returns to its original position under the action of the spring 323, causing the rollers 5 to contact the ground. This allows the header 2 to rise or fall, achieving an adaptive adjustment effect according to the terrain.

[0023] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
