[0002] A harvester is a machine used in modern agriculture for the pre-processing of crops. Its main function is to cut, transport and spread mature grains in the field to facilitate subsequent drying and threshing operations.

[0003] However, existing harvesters have the following shortcomings during operation: 1. Existing technology cannot flexibly control the height and angle of the header, requiring the entire header to be disassembled and adjusted, which cannot efficiently meet the operational needs of different crops and terrains; 2. When facing sloping mountainous or hilly fields, existing equipment, due to its rigid integrated frame structure, cannot compensate for terrain tilt by adjusting the relative angle of the frame, resulting in the header being too high or too low off the ground, affecting subsequent harvesting and drying operations; 3. Existing harvesters use a single transmission method and have a complex power distribution structure, making subsequent maintenance and repair inconvenient; those skilled in the art urgently need to solve the above technical problems.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0040] like Figure 1-4 As shown, the present invention provides a high ground clearance front wheel stalker, including a first frame 1, a second frame 2 hinged to the first frame 1, and a hydraulic drive mechanism 3 for driving the first frame 1 to rotate relative to the second frame 2.

[0041] The cutting platform device 4 is installed at the front end of the first frame 1 and is used to cut and dry crops; the lateral width of the cutting platform device 4 is greater than the lateral width of the first frame 1.

[0042] in,

[0043] A first power mechanism 5 is installed on the first vehicle frame 1. The first power mechanism 5 includes a gearbox 51, a transmission box 52, and a front drive wheel 53. The gearbox 51 is installed at the rear end of the first vehicle frame 1. The gearbox 51 has two output ends. One of the output ends is connected to a first drive shaft 54. The first drive shaft 54 ​​passes through the gearbox 51, and the transmission box 52 is connected to both ends of the first drive shaft 54. The output ends of the two transmission boxes 52 are connected to the front drive wheel 53 through a first drive shaft 55. The first vehicle frame 1 is mounted on the first drive shaft 55 in the middle.

[0044] The aforementioned header device 4 includes a support plate 41, a header frame 42, a separating mechanism 43, a cutting mechanism 44, a gearbox 45, a conveying mechanism 46, and a transmission mechanism 47. The support plate 41 is horizontally installed at the front end of the first frame 1, and the header frame 42 is vertically installed on the support plate 41. The gearbox 45 is installed on the header frame 42, and the gearbox 45 is connected to the cutting mechanism 44 and the conveying mechanism 46.

[0045] One end of the aforementioned transmission mechanism 47 is connected to the gearbox 45, and the other end is connected to the other output end of the aforementioned gearbox 51;

[0046] The working principle and beneficial effects of the above embodiments are as follows:

[0047] The present invention relates to a high ground clearance front wheel stalker, wherein the first power mechanism 5 provides power to the whole machine. The power is distributed by the gearbox 51, and part of it is transmitted to the two transmission boxes 52 on both sides through the first drive shaft 54, and then the front drive wheel 53 is driven to rotate through the first drive shaft 55 to realize the movement of the whole machine.

[0048] Another part is transmitted to the gearbox 45 of the header device 4 through the transmission mechanism 47. The gearbox 45 drives the cutting mechanism 44 and the conveying mechanism 46 to work. The separating mechanism 43 assists in the introduction of crops, the cutting mechanism 44 completes the cutting of crops, and the conveying mechanism 46 spreads the cut crops flat on one side of the field.

[0049] The first frame 1 is hinged to the second frame 2. The first frame 1 can be driven to rotate relative to the second frame 2 by the hydraulic drive mechanism 3, so as to realize the height adjustment or angle adjustment of the cutting platform device 4 to adapt to the height requirements of different terrains or crops.

[0050] The lateral width of the cutting platform device 4 is greater than that of the first frame 1, ensuring that the crops cut on one side and those not cut on the other side are all located in the area not covered by the front drive wheel 53 of the first frame 1, thus avoiding the front drive wheel 53 from crushing the crops.

[0051] The power transmission of this utility model is highly efficient. The power is centrally distributed by the gearbox 51, which simultaneously drives the first power mechanism 5 and the cutting table device 4. The transmission path is simple, power loss is reduced, and work efficiency is improved.

[0052] The width of the cutting platform device 4 of this utility model is greater than the width of the first frame 1, which effectively avoids the wheels from crushing the crops, ensures the cutting quality, and the sorting, cutting and conveying work together to ensure that the crops are cut and laid out neatly.

[0053] The hydraulic drive mechanism 3 of this utility model enables the first frame 1 to rotate relative to the second frame 2, which can flexibly adjust the stubble height of the cutting platform device, adapt to different crop heights, field slopes and other complex working conditions, and improve the adaptability of the whole machine;

[0054] The first frame 1 of this utility model is mounted on the first drive shaft 55 in the middle, which enhances the structural stability of the whole machine during travel and operation, reduces the impact of bumps on the cutting platform device 4, and the front wheel design can ensure a high ground clearance of the cutting platform device 4.

[0055] In one embodiment,

[0056] like Figure 5 As shown, the transmission mechanism 47 includes a second drive shaft 471 connected to another output end of the gearbox 51, and a small pulley 472 is connected to the end of the second drive shaft 471.

[0057] The transmission mechanism 47 also includes a second transmission shaft 473 rotatably mounted on the upper end of the support plate 41. The second transmission shaft 473 is arranged in parallel with the second drive shaft 471. A large pulley 474 is connected to one end of the second transmission shaft 473, and a sprocket 475 is connected to the other end.

[0058] A belt is fitted onto the small pulley 472 and the large pulley 474, and a chain is fitted onto the sprocket 475, and the gearbox 45 is driven by the chain.

[0059] The other output end of the gearbox 51 outputs power through the second drive shaft 471, which drives the small pulley 472 at the end of the drive to rotate. The second transmission shaft 473 synchronously drives the sprocket 475 at the other end to rotate, and then transmits the power to the gearbox 45 of the cutting table device through the chain, which finally drives the cutting mechanism 44 and the conveying mechanism 46 to operate.

[0060] The transmission adaptability design of this utility model combines belt drive and chain drive, which utilizes the flexibility of the belt to adapt to the small relative displacement between the frame and the cutting table, and the rigidity of the chain to ensure the stability of the power input of the gearbox 45.

[0061] In one embodiment,

[0062] A second power mechanism 6 is mounted on the second frame 2, and the front end of the second frame 2 is hinged to the transmission box 52.

[0063] The second power mechanism 6 includes a rear drive wheel assembly 61 and an engine 62. The engine 62 is mounted on the second frame 2 and is connected to and controls the gearbox 51. The rear drive wheel assembly 61 is mounted on the lower end of the second frame 2.

[0064] The engine 62 mounted on the second frame 2 is directly connected to and drives the gearbox 51. The front end of the second frame 2 is hinged to the transmission box 52, and the rear end is supported by the rear drive wheel assembly 61. In conjunction with the hydraulic drive mechanism 3, the relative angle between the first and second frames is adjusted to adapt to complex working conditions such as field slopes and improve the overall driving stability.

[0065] The engine 62 is mounted on the second frame 2, the cutting platform device 4 is positioned in front of the first frame 1, and the front and rear drive wheels are respectively supported at both ends of the frame. The power layout is reasonable and the center of gravity is balanced.

[0066] In one embodiment,

[0067] like Figure 6 As shown, the hydraulic drive mechanism 3 includes a hydraulic pump 31 mounted on the first frame 1 and a hydraulic cylinder 32 connected to the hydraulic pump 31 via a pipeline. The fixed end of the hydraulic cylinder 32 is hinged to the second frame 2, and its telescopic end is hinged to the transmission box 52.

[0068] The hydraulic pump 31 is installed on the first frame 1. The hydraulic pump 31 delivers high-pressure oil to the hydraulic cylinder 32 through the pipeline, driving the cylinder to extend and retract. When the hydraulic cylinder 32 extends, its extension end pushes the transmission box 52, causing the first frame 1 to rotate upward relative to the second frame 2 around the hinge point, raising the ground clearance of the cutting table device 4.

[0069] Conversely, by lowering the ground clearance of the header device 4, the attitude adjustment of the header device 4 can be precisely controlled, adapting to different crop heights or passing through low obstacles.

[0070] In one embodiment,

[0071] The above-mentioned crop separating mechanism 43 is installed on the front side of the header frame 42 to realize the separation and transportation of crops;

[0072] The aforementioned cutting mechanism 44 is installed at the lower part of the header frame 42 and cuts straw-type crops under the conveying action of the separating mechanism 43;

[0073] The aforementioned conveying mechanism 46 includes two conveying chains mounted side by side on the cutting frame 42, and a number of teeth mounted on the conveying chains and arranged at equal intervals, which convey the crops cut by the cutting mechanism 44 along the transmission direction of the conveying chains.

[0074] In summary:

[0075] This utility model discloses a high ground clearance front-wheel reamer with efficient power transmission. Power is centrally distributed by a gearbox. The transmission path of the first power mechanism and the reamer is simple, reducing power loss and improving work efficiency.

[0076] The width of the cutting platform device of this utility model is greater than the width of the first frame, which effectively avoids the wheels from crushing crops, ensures the cutting quality, and the sorting, cutting and conveying work together to ensure that the crops are cut and laid out neatly.

[0077] The hydraulic drive mechanism of this utility model enables the first frame to rotate relative to the second frame, which can flexibly adjust the stubble height of the header device to adapt to complex working conditions such as different crop heights and field slopes, thereby improving the overall adaptability of the machine.

[0078] The first frame of this utility model is mounted on the first drive shaft in the middle, which enhances the structural stability of the whole machine during travel and operation, reduces the impact of bumps on the cutting platform device, and the front wheel design can ensure a high ground clearance of the cutting platform device.
