Description

Technical Field

[0001] The present invention relates to the technical field of corn harvesters, in particular to a novel hilly and mountainous type corn harvester. Background Art

[0002] The existing corn harvesters do not have special supporting working devices to support operations in hilly and mountainous conditions, resulting in poor operating results and failure to meet customer economic needs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a new type of hilly and mountainous corn harvester, aiming to solve the problems in the prior art.

[0004] The technical solution of the present invention to solve the above technical problems is as follows:

[0005] A new type of hilly and mountainous corn harvester includes a cutting platform, an elevator and a movable frame. The cutting platform can be rotated up and down and is positioned at the front end of the frame; the elevator is installed on the frame at an angle and is located in the middle of the rear side of the cutting platform.

[0006] The beneficial effects of the present invention are as follows: during operation, the harvesting platform is used to harvest crops, and the crops are transported from both sides of the harvesting platform to the middle thereof to the elevator, so the operation efficiency is higher and the needs of customers can be met.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, it also includes an engine, which is fixedly mounted on the frame, located below the elevator, and is respectively connected to the cutting platform and the auger in the elevator.

[0009] The beneficial effects of adopting the above further solution are simple structure, reasonable design, and the engine provides power to the cutting platform and the elevator, without the need to set up separate drive parts, which makes transmission convenient.

[0010] Furthermore, the engine is arranged transversely along the frame.

[0011] The beneficial effects of adopting the above further solution are simple structure, reasonable lateral distribution of the engine, small space occupation, good coordination with other components, reduced transmission complexity, and easy maintenance.

[0012] Furthermore, it also includes a fan, which is fixedly installed on the engine.

[0013] The beneficial effects of adopting the above further solution are simple structure, reasonable design, and heat dissipation of the engine through the fan during operation, thereby ensuring the working performance of the engine.

[0014] Furthermore, a protective cover is included, which is fixed outside the engine and the fan, and its lower side and one side corresponding to the fan are open.

[0015] The beneficial effects of adopting the above further solution are simple structure, reasonable design, and the engine and fan are covered by the protective cover to prevent debris from falling into the high-temperature parts of the engine during operation and causing fire, which is safe and reliable.

[0016] Furthermore, it also includes a controller, a control valve and a temperature detector, wherein the control valve and the temperature detector are respectively connected to the controller through control lines, and the temperature detector is used to detect the water temperature of the engine and send a corresponding temperature signal to the controller; the controller receives the corresponding temperature signal and controls the control valve to make the fan back-blow when the temperature signal exceeds a set temperature threshold.

[0017] The beneficial effect of adopting the above further scheme is that during the operation, some debris will accumulate at the heat dissipation holes on one side of the water tank radiator on the engine and block the heat dissipation holes, seriously affecting the heat dissipation effect; when the water temperature of the engine exceeds the set temperature threshold, the controller can control the above control valve to reverse the fan for backblowing to blow away the debris accumulated at the heat dissipation holes of the water tank radiator, so that the water tank radiator can dissipate heat normally and ensure the heat dissipation effect.

[0018] Furthermore, the elevator includes an upper shell and a lower shell, the lower shell is installed on the frame at an angle, a feed port is provided at its lower end, and its upper end is open; the lower shell is located in the middle of the rear side of the cutting table, its lower end is transmission connected to the cutting table, and it can rotate with the cutting table; the upper shell is fixedly installed on the frame at an angle, its lower end is open, and a discharge port is provided at its upper end; the upper shell is located above the lower shell, and its lower end cover is outside the upper end of the lower shell, and is rotatably connected to the upper end of the lower shell.

[0019] The beneficial effect of adopting the above further solution is that during operation, the lower housing can rotate up and down as the cutting platform rotates up and down, avoiding the problem of the lower end of the lower housing being close to the ground and causing poor vehicle trafficability;

[0020] In addition, dividing the elevator into an upper shell and a lower shell can not only solve the problem of poor vehicle passability, but also ensure the normal transportation of materials. It has a simple structure and a reasonable design.

[0021] Furthermore, both sides of the lower end of the lower shell are rotatably connected to one end of two transition plates respectively, and the other ends of the two transition plates are rotatably connected to the header respectively.

[0022] The beneficial effect of adopting the above further solution is that the structure is simple and the design is reasonable. The cutter bar is connected to the lower end of the lower housing through a transition plate, which can not only ensure that the lower housing can rotate up and down adaptively with the cutter bar, but also prevent the cutter bar and the lower housing from affecting each other.

[0023] Further, the cutter bar is connected to the vehicle frame through a rotary oil cylinder, and both ends of the rotary oil cylinder are rotatably connected to the cutter bar and the vehicle frame respectively.

[0024] The beneficial effect of adopting the above further solution is that during operation, the cutter bar is driven by the rotary oil cylinder to rotate up and down for harvesting operations.

[0025] Further, two front wheels are relatively rotatably installed at the front end of the bottom of the vehicle frame, and two rear wheels are relatively rotatably installed at the rear end of the bottom of the vehicle frame. The diameters of the two front wheels and the two rear wheels are the same.

[0026] The beneficial effect of adopting the above further solution is that the structure is simple and the design is reasonable. The diameters of the front wheels and the rear wheels are kept the same, so that there is no differential between the front wheels and the rear wheels, eliminating components such as differentials, and greatly improving the stability and reliability of the whole machine.

[0040] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0041] Embodiment 1

[0042] As Figures 1 to 8 shown, this embodiment provides a new type of hilly and mountainous corn harvester, including a header 1, an elevator and a movable frame 2. The header 1 is rotatably mounted up and down and positioned at the front end of the frame 2; the elevator is obliquely mounted on the frame 2 and is located in the middle at the rear side of the header 1.

[0043] During operation, the header 1 performs harvesting, and the crops are conveyed from both sides of the header 1 to the middle thereof to the elevator, with higher operation efficiency and being able to meet the needs of customers.

[0044] It should be noted that the above-mentioned header 1 adopts existing technology, and its specific structure and principle are not described in detail here.

[0045] In traditional technology, the elevator is located on one side of the frame 2, that is, the elevator is located on one side of the cutting platform 1. In this solution, the crops harvested by the cutting platform 1 need to be transported from one side of the cutting platform 1 to the other side to deliver the crops to the elevator, and the harvesting efficiency is lower than the above solution.

[0046] Preferably, in this embodiment, a cab 11 is fixedly mounted on the vehicle frame 2 near the front end thereof.

[0047] Example 2

[0048] On the basis of Example 1, this embodiment further includes an engine 3, which is fixedly mounted on the vehicle frame 2, is located below the elevator, and is respectively connected to the cutting platform 1 and the auger in the elevator.

[0049] This solution has a simple structure and a reasonable design. The engine 3 provides power for the cutting platform 1 and the elevator, and there is no need to set up separate driving parts, which makes transmission convenient.

[0050] It should be noted that the above-mentioned engine 3 adopts existing technology, and its specific structure and principle are not described in detail here.

[0051] In addition, the transmission structure and transmission relationship between the engine 3 and the cutting platform 1 and the elevator are all based on the existing technology and will not be described in detail here.

[0052] Moreover, the engine 3 can drive the cutting platform 1 to turn up and down, and can also drive the auger in the elevator to rotate to transport materials.

[0053] Example 3

[0054] On the basis of embodiment 2, in this embodiment, the engine 3 is arranged transversely along the frame 2 (ie, extending from one side of the frame 2 to the other side).

[0055] This solution has a simple structure, the engine 3 is reasonably distributed laterally, occupies a small space, can cooperate well with other components, reduces the complexity of the transmission, and is easy to maintain.

[0056] In conventional technology, the engine 3 is arranged along the direction from the front end to the rear end of the vehicle frame 2, occupying a large volume.

[0057] Example 4

[0058] On the basis of any one of Embodiments 2 to 5, this embodiment further includes a fan 4 , which is fixedly mounted on the engine 3 .

[0059] This solution has a simple structure and a reasonable design. During operation, the engine 3 is cooled by the fan 4 to ensure the working performance of the engine 3.

[0060] Embodiment 5

[0061] Based on Embodiment 4, this embodiment further includes a protective cover 5. The protective cover 5 is fixedly covered outside the engine 3 and the fan 4, and its lower side and the side corresponding to the fan 4 are open.

[0062] This solution has a simple structure and a reasonable design. The engine 3 and the fan 4 are covered by the protective cover 5 to prevent debris from falling onto the high-temperature part of the engine 3 during operation, which may cause a fire, ensuring safety and reliability.

[0063] Preferably, in this embodiment, the above-mentioned protective cover 5 preferably has a rectangular body structure with a regular shape.

[0064] In addition, multiple avoidance grooves for avoiding corresponding components are provided at the edge of its lower side.

[0065] Embodiment 6

[0066] Based on any one of Embodiments 4 to 5, this embodiment further includes a controller, a control valve, and a temperature detector. The control valve and the temperature detector are respectively connected to the controller through control lines. The temperature detector is used to detect the water temperature of the engine 3 and send the corresponding temperature signal to the controller; the controller receives the corresponding temperature signal and controls the control valve to make the fan 4 blow in the reverse direction when the temperature signal exceeds the set temperature threshold.

[0067] During the operation process, some debris will accumulate at the heat dissipation holes on one side of the upper water tank radiator of the engine 3 and block the heat dissipation holes, seriously affecting the heat dissipation effect; when the water temperature of the engine 3 exceeds the set temperature threshold, the controller can control the above-mentioned control valve at this time to make the fan reverse and blow, so as to blow off the debris accumulated at the heat dissipation holes of the water tank radiator, so that the water tank radiator can dissipate heat normally and ensure the heat dissipation effect.

[0068] Preferably, in this embodiment, the above-mentioned water tank radiator is located at the open side of the protective cover 5, with a reasonable design, which can not only prevent debris from falling on the water tank radiator and causing a fire, but also prevent the protective cover 5 from affecting the heat dissipation of the water tank radiator.

[0069] Based on the above solution, the above-mentioned temperature detector uses a temperature sensor, which is fixedly installed on the engine 3 and used to detect the water temperature of the engine 3.

[0070] Preferably, in this embodiment, the above-mentioned control valve preferably controls a solenoid valve.

[0071] Embodiment 7

[0072] Based on the above embodiments, in this embodiment, the elevator includes an upper housing 6 and a lower housing 7. The lower housing 7 is inclined and installed on the vehicle frame 2, with a feed inlet provided at its lower end and an open upper end; the lower housing 7 is located in the middle at the rear side of the cutter bar 1, its lower end is in transmission connection with the cutter bar 1, and it can rotate together with the cutter bar 1; the upper housing 6 is inclined and fixedly installed on the vehicle frame 2, with an open lower end and a discharge outlet provided at its upper end; the upper housing 6 is located above the lower housing 7, and its lower end covers the outside of the upper end of the lower housing 7 and is rotatably connected to the upper end of the lower housing 7.

[0073] During operation, the lower housing 7 can rotate up and down as the cutter bar 1 rotates up and down, avoiding the problem that the lower end of the lower housing 7 is close to the ground, resulting in poor passability of the vehicle.

[0074] In addition, dividing the elevator into the upper housing 6 and the lower housing 7 can not only solve the problem of poor passability of the vehicle, but also ensure the normal conveying of materials. The structure is simple and the design is reasonable.

[0075] It should be noted that the structure for conveying materials inside the upper housing 6 and the lower housing 7 is prior art and will not be elaborated here.

[0076] In the traditional technology, the elevator is integrally formed. In this solution, the height that the elevator can pass through is limited, the passability is poor, and the failure rate is high.

[0077] However, the split design of the elevator in this embodiment can increase the passing height of the elevator, has better passability, and a low failure rate.

[0078] Preferably, in this embodiment, an avoidance opening that penetrates through inside and outside and has an open lower end is provided on the upper side of the lower end of the upper housing 6. The avoidance opening is used to avoid the lower housing 7. This solution has a simple structure and a reasonable design. By designing the avoidance opening, the up and down rotation of the lower housing 7 can be effectively avoided, ensuring that the lower housing 7 can rotate up and down with the cutter bar 1.

[0079] Embodiment 8

[0080] Based on Embodiment 7, in this embodiment, both sides of the lower end of the lower housing 7 are rotatably connected to one end of two transition plates 8, and the other ends of the two transition plates 8 are respectively rotatably connected to the cutter bar 1.

[0081] This solution has a simple structure and a reasonable design. The lower end of the cutter bar 1 and the lower housing 7 are connected by the transition plates 8, which can not only ensure that the lower housing 7 can adaptively rotate up and down with the cutter bar 1, but also ensure that there is enough space between the lower end of the lower housing 7 and the cutter bar 1 for the lower housing 7 to rotate, avoiding mutual influence between the cutter bar 1 and the lower housing 7.

[0082] Preferably, in this embodiment, one side of the lower end of the lower housing 7 can be rotatably connected to the cutting table 1 through a transition plate 8, or can be rotatably connected to the cutting table 1 through a plurality of transition plates 8, such as two transition plates 8. Comparatively speaking, this solution can further increase the connection stability and strength between the lower housing 7 and the cutting table 1.

[0083] Based on the above solution, one end of the cutting table 1 is rotatably connected to the vehicle frame 2 up and down through a pin shaft, and the upper end of the lower housing 7 is rotatably connected to the lower end of the upper housing 6 through a pin shaft.

[0084] In addition, a cross beam is fixedly installed on the cutting table 1, hanging plates are respectively fixedly installed at both ends of the cross beam, and the corresponding ends of the two transition plates 8 are respectively rotatably connected to the two hanging plates through pin shafts (see Figure 8 ).

[0085] Preferably, in this embodiment, the above-mentioned transition plate 8 has a long strip plate-like structure, with a simple structure and regular shape, and can realize the connection between the cutting table 1 and the lower housing 7.

[0086] In addition to the above implementation manner, the above-mentioned transition plate 8 can also adopt other suitable geometric shapes, such as an arc plate.

[0087] Embodiment 9

[0088] Based on the above embodiments, in this embodiment, the cutting table 1 is connected to the vehicle frame 2 through a rotary oil cylinder, and both ends of the rotary oil cylinder are respectively rotatably connected to the cutting table 1 and the vehicle frame 2.

[0089] During operation, the cutting table 1 is driven by the rotary oil cylinder to rotate up and down for harvesting operations.

[0090] Embodiment 10

[0091] Based on the above embodiments, in this embodiment, two front wheels 9 are relatively rotatably installed at the front end of the bottom of the vehicle frame 2, and two rear wheels 10 are relatively rotatably installed at the rear end of the bottom of the vehicle frame 2, and the wheel diameters of the two front wheels 9 and the two rear wheels 10 are the same.

[0092] This solution has a simple structure and reasonable design. The wheel diameters of the front wheels 9 and the rear wheels 10 are kept the same, so that there is no differential between the front wheels 9 and the rear wheels 10, eliminating components such as differentials, and greatly improving the stability and reliability of the whole machine.

[0093] The present invention realizes the product goals of good harvesting effect, good passability, high reliability and safety by adopting a series of technologies specially designed for hilly and mountainous areas, such as the technology of centering the elevator, the technology of horizontally installed engine, the technology of fan back blowing, and the four-wheel drive technology with the same wheel size.

[0094] The present invention designs a corn ear harvester that is truly suitable for operating in hilly and mountainous areas. It is a product with good harvesting effect, good passability, high reliability and safety, which can solve the problems of agricultural mechanization for the society and has relatively good economic benefits.
