Description

Technical Field

[0001] This utility model relates to the field of harvester equipment technology, specifically to a grain unloading hopper with multi-angle control. Background Technology

[0002] In the process of grain harvesting and storage, the coordinated use of wheat harvesters and unloading vehicles is crucial. Traditional unloading devices often only allow unloading at fixed angles and heights, which not only limits the flexibility of unloading but also increases the difficulty and cost of operation.

[0003] Most grain unloading devices on the market currently use grain unloading cylinders to transfer grain. However, when the specifications of the unloading vehicle and the unloading cylinder do not match during the transportation process, the angle and height of the unloading cylinder need to be adjusted. The existing operating methods can only adjust the height of the unloading cylinder and then fix it to meet the change in transportation height. However, this method is inefficient and has limited fixing strength to the unloading cylinder, which is prone to falling off, greatly reducing the efficiency of grain transfer. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a grain unloading hopper that can be adjusted at multiple angles while also allowing for height adjustment at the discharge end. It features a simple structure and can be used with wheat harvesters and various sizes of unloading vehicles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-angle controlled grain unloading hopper, comprising a frame, on which a storage chamber, a conveying auger, and a conveying bend are provided. An angle adjustment device is provided at the connection between the storage chamber and the conveying bend. The conveying bend is rotatably connected to the conveying auger. A height adjustment device is provided at the connection between the conveying bend and the conveying auger.

[0006] As a further improvement to the above technical solution: The angle adjustment device includes a bearing seat, the lower part of which is rotatably connected to the discharge port of the storage chamber, and the upper part is fixedly connected to the conveying auger. An angle adjustment cylinder connected to the outer wall of the bearing seat is provided on the frame.

[0007] The height adjustment device includes a support set on the outer wall of the conveying bend, a height adjustment cylinder set on the support, and a cross brace connected to the height adjustment cylinder set on the side wall of the conveying auger.

[0008] One end of the cross brace is provided with a positioning seat that connects to the side wall of the conveying auger, and the other end is provided with a positioning plate that connects to the conveying bend.

[0009] The end of the conveying bend facing the conveying auger is provided with a connecting sleeve, and the end of the conveying auger is provided with a plug-in sleeve that cooperates with the connecting sleeve. The connecting sleeve and the plug-in sleeve are rotatably connected.

[0010] Both the connecting sleeve and the insertion sleeve have annular extension plates on their outer walls, and the two annular extension plates are connected by a fastening seat.

[0011] The beneficial effects of this utility model embodiment are as follows: The multi-angle controlled grain unloading hopper includes a frame, on which a storage chamber, a conveying auger, and a conveying bend are provided. An angle adjustment device for adjusting the horizontal discharge position of the discharge port is provided at the connection between the storage chamber and the conveying bend. The conveying bend is rotatably connected to the conveying auger, and a height adjustment device for adjusting the longitudinal position of the discharge port is provided at the connection between the conveying bend and the conveying auger. By using the angle adjustment device and the height adjustment device, the discharge position of the conveying auger can be adjusted in multiple stages. Compared with the existing adjustment method, the adjustment efficiency is higher and the accuracy is more precise. It can meet the requirements of the unloading hopper and various different unloading vehicles, and improve the efficiency of grain transfer. Attached Figure Description

[0014] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0015] like Figure 1-4As shown, the multi-angle controlled grain unloading hopper of this embodiment includes a frame 1, on which a storage chamber 2, a conveying auger 3, and a conveying bend 4 are provided. An angle adjustment device 5 for adjusting the horizontal discharge position of the discharge port is provided at the connection between the storage chamber 2 and the conveying bend 4. The conveying bend 4 is rotatably connected to the conveying auger 3. A height adjustment device 6 for adjusting the longitudinal position of the discharge port is provided at the connection between the conveying bend 4 and the conveying auger 3. The discharge position of the conveying auger 3 can be adjusted in multiple stages using the angle adjustment device 5 and the height adjustment device 6. Compared with the existing adjustment method, the adjustment efficiency is higher and the accuracy is more precise. It can meet the requirements of the unloading hopper and various different unloading vehicles, and improve the efficiency of grain transfer.

[0016] The angle adjustment device 5 includes a bearing seat 7. The lower part of the bearing seat 7 is rotatably connected to the discharge port of the storage chamber 2, and the upper part is fixedly connected to the conveying auger 3. An angle adjustment cylinder 8 is provided on the frame 1 and connected to the outer wall of the bearing seat 7. The fixed end of the angle adjustment cylinder 8 is connected to the frame 1, and the telescopic end is connected to the bearing seat 7.

[0017] The height adjustment device 6 includes a support 9 on the outer wall of the conveying bend 4, and a height adjustment cylinder 10 is provided on the support 9. A cross brace 11 connected to the height adjustment cylinder 10 is provided on the side wall of the conveying auger 3.

[0018] One end of the cross brace 11 is provided with a positioning seat 12 that is connected to the side wall of the conveying auger 3, and the other end is provided with a positioning plate 13 that is connected to the conveying bend 4. The design of the positioning seat 12 and the positioning plate 13 can strengthen the fixation of the cross brace 11, making it easier for it to drive the conveying auger 3 to rotate.

[0019] The end of the conveying bend 4 facing the conveying auger 3 is provided with a connecting sleeve 14, and the end of the conveying auger 3 is provided with a plug sleeve 15 that works with the connecting sleeve 14. The connecting sleeve 14 and the plug sleeve 15 are rotatably connected, and a sealing ring is provided at the connection to ensure that the conveying auger 3 will not leak material when it rotates.

[0020] Both the connecting sleeve 14 and the insertion sleeve 15 are provided with annular extension plates 16 on their outer side walls. The two annular extension plates 16 are connected by fastening seats 17. The fastening seats 17 are U-shaped seats, and the inner side walls are provided with pads that fit against the annular extension plates.

[0021] The working principle / assembly process of this solution is as follows: The conveying bend 4 is installed between the storage chamber 2 and the conveying auger 3. The bottom of the conveying bend 4 is connected to the bearing seat 7. When the angle adjustment cylinder 8 extends or retracts, the conveying bend 4 can rotate with the bearing seat 7, thereby changing the horizontal discharge position of the conveying auger 3. The height adjustment cylinder 10 can drive the conveying auger 3 to rotate when it extends or retracts, thereby changing the discharge height of the conveying auger. Both the angle adjustment cylinder 8 and the height adjustment cylinder 10 are controlled by solenoid valves. The lifting buttons of the angle adjustment cylinder 8 and the height adjustment cylinder 10 are controlled on the operating panel. There are also one-key adjustment and one-key reset buttons for one-key control of the conveying auger 3 to move to the discharge position or to reset.
