Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a novel hydraulic system for a tracked corn harvester. Background Technology

[0002] During operation, the engine dust cover of a tracked corn harvester is prone to clogging, which can lead to high engine temperatures. Therefore, it is necessary to add a forward and reverse rotation function for the engine fan to ensure heat dissipation efficiency. However, the existing hydraulic system of the tracked corn harvester is a series system consisting of two valve blocks. One valve block connects to the grain bin and clutch, while the other valve block connects to the header and steering. This causes the actions of the two valve blocks to be out of sync. As a result, when it is necessary to control the forward and reverse rotation of the engine fan, an additional gear pump is required, which increases the cost.

[0003] Therefore, this utility model provides a novel hydraulic system for a tracked corn harvester. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a novel hydraulic system for tracked corn harvesters, thereby solving the problems mentioned in the background section. The first valve block, second valve block, and third valve block of this utility model can work synchronously, which can save the gear pump from driving the engine fan to rotate in both directions, reducing the cost of the device; it can also prevent the valve from generating negative pressure and ensure the safety of the valve.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel hydraulic system for a tracked corn harvester, comprising a first valve block, a second valve block, and a third valve block, with pipes installed between the first, second, and third valve blocks. An engine fan is connected to the first valve block via pipes, a grain bin and a main clutch are connected to the second valve block via pipes, and a cutter and a steering mechanism are connected to the third valve block via pipes. Multiple valves are installed within each of the first, second, and third valve blocks, with the valves corresponding to the pipes. Both ends of the valves are equipped with anti-negative pressure structures.

[0006] Furthermore, the anti-negative pressure structure includes a piston, which is slidably fitted at both ends of the valve.

[0007] Furthermore, electromagnets are fixed at both ends of the valve, and the electromagnets correspond to the piston.

[0008] Furthermore, a first electrode plate is fixed at both ends of the valve, and a second electrode plate is fixed on the piston, with the first electrode plate corresponding to the second electrode plate.

[0009] Furthermore, both the first and second electrode plates are connected to the electromagnet via wires.

[0010] Furthermore, a magnetic block is fixed to the side of the piston near the electromagnet, and the magnetic block is arranged opposite to the magnetic poles of the electromagnet.

[0011] Furthermore, multiple valves within the first, second, and third valve blocks are connected in parallel via pipelines.

[0012] The beneficial effects of this utility model are as follows: The new hydraulic system of the tracked corn harvester includes a first valve block; a second valve block; a third valve block; pipes; an engine fan; a grain bin; a main clutch; a header; a steering column; valves; and an anti-negative pressure structure.

[0013] Pipes are installed between the first, second, and third valve blocks, allowing the engine fan, grain bin, main clutch, cutter, and steering to form a parallel structure. The first, second, and third valve blocks can work synchronously, thus saving the need for a gear pump to drive the engine fan in both directions and reducing the cost of the device. Anti-negative pressure structures are installed at both ends of the valves to prevent negative pressure from being generated and to ensure valve safety. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a new type of hydraulic system for a tracked corn harvester, including a first valve block 1, a second valve block 2, and a third valve block 3. A pipe 4 is installed between the first valve block 1, the second valve block 2, and the third valve block 3. An engine fan 5 is connected to the first valve block 1 through the pipe 4. A grain bin 6 and a main clutch 7 are connected to the second valve block 2 through the pipe 4. A cutter 8 and a steering wheel 9 are connected to the third valve block 3 through the pipe 4. Multiple valves 10 are installed in the first valve block 1, the second valve block 2, and the third valve block 3. The valves 10 correspond to the pipes 4. Anti-negative pressure structures 11 are installed at both ends of the valves 10.

[0021] In this embodiment, the anti-negative pressure structure 11 includes a piston 13, which is slidably fitted to both ends of a valve 10. Electromagnets 12 are fixed to both ends of the valve 10, and the electromagnets 12 correspond to the piston 13. First electrode plates 14 are fixed to both ends of the valve 10, and second electrode plates 15 are fixed to the piston 13. The first electrode plates 14 and the second electrode plates 15 correspond to each other. The first electrode plates 14 and the second electrode plates 15 are both connected to the electromagnets 12 by wires. A magnetic block 16 is fixed to the side of the piston 13 near the electromagnet 12, and the magnetic block 16 is arranged opposite to the magnetic poles of the electromagnet 12.

[0022] Specifically, when negative pressure is generated in valve 10, hydraulic oil will push piston 13, causing piston 13 to move second electrode plate 15 and magnetic block 16, so that first electrode plate 14 and second electrode plate 15 come into contact, thereby controlling electromagnet 12 to start, so that electromagnet 12 pushes magnetic block 16, thereby pushing piston 13 to move, thus reducing the impact of negative pressure.

[0023] Multiple valves 10 within the first valve block 1, the second valve block 2, and the third valve block 3 are connected in parallel via pipe 4.

[0024] Specifically, the existing two valve blocks are split into a first valve block 1, a second valve block 2, and a third valve block 3, thereby realizing the parallel design of each working group, so that each working group can work synchronously, thereby driving the engine fan 5 to rotate in both directions without the need for a gear pump.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
