Description

Technical Field

[0001] This utility model relates to the field of gearbox control technology, and in particular to a control device for an agricultural machinery gearbox controller. Background Technology

[0002] With the development of modern agriculture, the performance requirements of agricultural machinery are increasing, especially in terms of efficiency, reliability and intelligence. As an indispensable part of agricultural machinery, the gearbox undertakes the important task of transmitting power and adjusting speed.

[0003] However, traditional gearbox control methods often exhibit slow response, inconvenient operation, and lack of intelligent management when faced with complex and ever-changing working environments, especially for agricultural machinery that operates under high loads for extended periods.

[0004] Traditional transmissions typically lack effective temperature monitoring mechanisms, making it difficult to keep track of the actual temperature changes of the internal lubricating oil in real time. Once the transmission overheats, it will not only accelerate component wear, but may also lead to system failure or even shutdown in severe cases. Utility Model Content

[0005] Based on this, it is necessary to provide a control device for an agricultural machinery gearbox controller to address the above-mentioned technical problems. The device uses an oil pump to exchange heat with the lubricating oil. The lubricating oil enters the cooling chamber from the inlet pipe and flows into the heat exchange chamber through the heat dissipation pipe. After sufficient heat exchange, the lubricating oil is finally discharged through the outlet pipe, completing a cycle. This effectively prevents component wear and failure caused by overheating and greatly extends the service life of the gearbox and its related components.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A control device based on an agricultural machinery gearbox controller is applied to agricultural machinery gearboxes.

[0008] The control device specifically includes:

[0009] At least one temperature sensor is used to monitor the real-time temperature of the lubricating oil inside the agricultural machinery gearbox and output the corresponding temperature signal.

[0010] The control unit is connected to the temperature sensor, receives the temperature signal, performs a cooling operation according to a preset temperature threshold, and controls the cooling oil pump to work.

[0011] A heat dissipation box is installed inside the agricultural machinery gearbox. It contains a cooling chamber and a heat exchange chamber. An inlet pipe is fixedly installed on the cooling chamber. A heat dissipation pipe is fixedly installed between the cooling chamber and the heat exchange chamber. An outlet pipe is fixedly installed on the heat exchange chamber.

[0012] In a preferred embodiment of the agricultural machinery gearbox controller control device provided by this utility model, a spiral channel is fixedly installed in the heat exchange chamber, one end of the spiral channel is connected to the heat dissipation pipe, and the other end of the spiral channel is connected to the liquid outlet pipe.

[0013] In a preferred embodiment of the agricultural machinery gearbox controller provided by this utility model, the heat dissipation pipe is S-shaped when viewed from above.

[0014] In a preferred embodiment of the agricultural machinery gearbox controller control device provided by this utility model, fins are fixedly installed on the heat dissipation pipe.

[0015] As a preferred embodiment of the agricultural machinery gearbox controller control device provided by this utility model, the spiral channel is provided with two layers, one layer for circulating coolant and the other layer for circulating heat exchange fluid.

[0016] In a preferred embodiment of the agricultural machinery gearbox controller control device provided by this utility model, an exchange chamber is fixedly installed inside the heat dissipation box, and exchange pipes are fixedly installed at both ends of the spiral channel where the heat exchange fluid is located.

[0017] In a preferred embodiment of the agricultural machinery gearbox controller control device provided by this utility model, a one-way valve is fixedly installed inside the exchange pipe.

[0018] In a preferred embodiment of the agricultural machinery gearbox controller control device provided by this utility model, the diameter area of ​​the heat dissipation pipe is S1, the diameter area of ​​the exchange pipe is S2, and S1:S2 = 2:1.

[0019] In a preferred embodiment of the agricultural machinery gearbox controller provided by this utility model, the heat dissipation box is provided with heat dissipation holes that penetrate through both sides of the heat dissipation box.

[0020] In a preferred embodiment of the agricultural machinery gearbox controller provided by this utility model, a cloth strip is fixedly connected to the inner wall of the heat dissipation box.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The agricultural machinery gearbox controller provided by this utility model uses an oil pump to exchange heat with the lubricating oil. The lubricating oil enters the cooling chamber from the inlet pipe and flows into the heat exchange chamber through the heat dissipation pipe. After sufficient heat exchange, the lubricating oil is finally discharged through the outlet pipe, completing a cycle. This effectively prevents component wear and failure caused by overheating and greatly extends the service life of the gearbox and its related components.

[0023] Since the diameter area S1 of the heat exchanger tube is twice that of the diameter area S2 of the heat exchange tube, the lubricating oil can maintain an appropriate flow rate while dissipating enough heat, thus dissipating heat more fully. The heat exchange fluid has a faster flow rate in the heat exchange tube, which helps to quickly carry the heat out of the system. Attached Figure Description

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0035] As described in the background section, traditional transmissions typically lack an effective temperature monitoring mechanism, making it difficult to monitor the actual temperature changes of the internal lubricating oil in real time. Once the transmission overheats, it will not only accelerate component wear, but may also lead to system failure or even shutdown in severe cases.

[0036] To solve this technical problem, this utility model provides a control device for an agricultural machinery gearbox controller, which is applied to an agricultural machinery gearbox.

[0037] Example 1:

[0038] Reference Figures 1-3 A control device for an agricultural machinery gearbox controller includes at least one temperature sensor 10, a control unit 20, and a heat sink 30.

[0039] Specifically, the temperature sensor 10 is installed at a key location in the agricultural machinery gearbox, such as the oil pan or near the main heat-generating components, to monitor the real-time temperature of the lubricating oil inside the gearbox and output a corresponding temperature signal. The control unit 20 is connected to the temperature sensor 10, receives the temperature signal, performs cooling operations according to a preset temperature threshold, and controls the cooling oil pump to operate. The radiator box 30 is installed inside the agricultural machinery gearbox and contains a cooling chamber 31 and a heat exchange chamber 32. An inlet pipe 311 is fixedly installed on the cooling chamber 31, a heat dissipation pipe 33 is fixedly installed between the cooling chamber 31 and the heat exchange chamber 32, and an outlet pipe 321 is fixedly installed on the heat exchange chamber 32. The radiator box 30 has heat dissipation holes 35 that penetrate both sides of the radiator box 30, enhancing the effect of natural ventilation and heat dissipation. Furthermore, a cloth strip 40 is fixedly connected to the inner wall of the radiator box 30 to turbulent the internal space.

[0040] Reference Figure 2 A spiral channel 322 is fixedly installed inside the heat exchange chamber 32. One end of the spiral channel 322 is connected to the heat dissipation pipe 33, and the other end of the spiral channel 322 is connected to the liquid outlet pipe 321. This extends the residence time of the lubricating oil in the heat exchanger, improves the heat exchange efficiency, and the spiral path design can better distribute the flow of lubricating oil, ensuring uniform heat dissipation.

[0041] With the above-described structure, the temperature sensor 10 continuously monitors the temperature of the lubricating oil inside the transmission and transmits the temperature data to the control unit 20. After receiving the temperature data, the control unit 20 determines whether cooling is required based on a preset temperature threshold. If the detected temperature exceeds the set safety range, the control unit 20 will initiate a cooling program, adjusting the oil pump's operating speed to increase the lubricating oil flow. The lubricating oil enters the cooling chamber 31 from the inlet pipe 311, where it dissipates some heat before entering the heat exchange chamber 32 through the heat dissipation pipe 33. In the heat exchange chamber 32, the lubricating oil flows through the spiral channel 322, further promoting heat dissipation. Finally, the fully cooled lubricating oil is discharged through the outlet pipe 321, completing the cycle. In addition to the above-described active cooling mechanism, the heat dissipation holes 35 on the radiator 30 and the cloth strips 40 on the inner wall also play an auxiliary role in heat dissipation, improving overall heat dissipation performance by enhancing air circulation and increasing the contact area.

[0042] Example 2

[0043] The control device for the agricultural machinery gearbox controller provided in Example 1 is further optimized, specifically, as follows: Figure 2 and Figure 3 As shown, from a top view, the heat pipe 33 is S-shaped, and fins 331 are fixedly installed on the heat pipe 33.

[0044] Through the above structural design, the S-shape not only increases the flow path length of the lubricating oil within the heat exchange box 30, but also improves heat exchange efficiency by increasing the degree of fluid turbulence. Compared to straight pipes, the S-shaped layout allows the lubricating oil to have more sufficient contact with the surrounding environment or heat exchange medium, thereby improving the heat transfer effect. To further enhance the heat dissipation effect, fins 331 are fixedly installed on the heat exchange pipe 33. These fins 331 significantly increase the surface area of ​​the heat exchange pipe 33, allowing more heat to be dissipated quickly. With the disturbance of the cloth strip 40, the accumulation of dust on the surface of the fins 331 is reduced, maintaining a good heat exchange area.

[0045] Example 3

[0046] The control device for the agricultural machinery gearbox controller provided in Embodiment 1 or 2 is further optimized, specifically, as follows: Figure 2 As shown, the spiral channel 322 is provided with two layers, one for the flow of lubricating oil and the other for the flow of heat exchange fluid.

[0047] Referring to the figure, an exchange chamber 34 is fixedly installed inside the heat sink 30. Exchange pipes 341 are fixedly installed at both ends of the spiral channel 322 where the heat exchange liquid is located. Furthermore, a one-way valve is fixedly installed inside the exchange pipe 341.

[0048] With the above-described structure, the spiral channel 322 adopts a double-layer design. One layer is dedicated to the flow of lubricating oil, responsible for dissipating heat from the heat dissipation pipe 33; the other layer is for the flow of heat exchange fluid, which exchanges heat with the lubricating oil to carry away the heat. Although the lubricating oil and heat exchange fluid flow in different layers, they interact through specific design to ensure that heat can be effectively transferred from the lubricating oil to the heat exchange fluid. For example, the two layers can be connected by a highly efficient thermally conductive material or structure to promote effective heat transfer. The exchange chamber 34, as an important node for the heat exchange fluid to enter and exit the spiral channel 322, provides sufficient space for the heat exchange fluid to fully exchange heat with the external environment or other cooling media. To ensure that the heat exchange fluid flows in a predetermined direction and to avoid backflow, one-way valves are fixedly installed inside the exchange pipe 341. These one-way valves ensure that the liquid can only flow in one direction, preventing efficiency loss or equipment damage caused by fluid backflow.

[0049] Example 4

[0050] The agricultural machinery gearbox controller control device provided in the above embodiments is further optimized, specifically, as follows: Figure 2 As shown, the diameter area of ​​heat dissipation pipe 33 is S1, and the diameter area of ​​heat exchange pipe 341 is S2, with S1:S2 = 2:1.

[0051] Based on the fundamental principles of fluid mechanics, the flow velocity of a liquid is inversely proportional to the cross-sectional area of ​​the pipe. To ensure the flow efficiency of lubricating oil and heat exchange fluid in the system, and to avoid pressure loss or insufficient heat exchange caused by excessively fast or slow flow velocities, the flow rate and velocity can be rationally distributed by adjusting the ratio of pipe diameter to area.

[0052] In this design, the diameter area of ​​the heat dissipation pipe 33 is S1, which is twice the diameter area of ​​the heat exchange pipe 341, S2, i.e., S1:S2=2:1. This design makes the flow rate of the lubricating oil in the heat dissipation pipe 33 slower, so that the heat can be dissipated more fully, while the flow rate of the heat exchange fluid in the heat exchange pipe 341 is faster, which helps to quickly carry the heat out of the system.

[0053] Example 5

[0054] The agricultural machinery gearbox controller control device provided in the above embodiments is further optimized, specifically, as follows: Figure 4 As shown, a mounting base 50 is fixedly installed on the heat dissipation pipe 33, and a fan blade 51 is installed on the mounting base 50. A gravity ball 52 is installed on the fan blade 51 through an elastic element. Preferably, the elastic element is a spring 53, which allows the gravity ball 52 to oscillate periodically when the fan blade 51 rotates.

[0055] With the above structure, during the operation of the agricultural machinery, the external airflow drives the fan blade 51 to rotate, and the fan blade 51 drives the gravity ball 52 on it to rotate together. Since the gravity ball 52 is flexibly connected by the spring 53, a dynamic balance between centrifugal force and elastic restoring force will be generated during the rotation, which will trigger periodic oscillation and rebound motion. These oscillation actions will transmit local vibration to the area where the fan blade 51 is located, and further transmit it to the heat dissipation pipe 33 and its fins 331 surface. The vibration will shake off the dust, impurities and other debris attached to the fins 331 surface, thereby achieving the purpose of automatic cleaning.

[0056] The operation process of the agricultural machinery gearbox controller provided by this utility model is as follows: First, ensure that all components, including temperature sensor 10, control unit 20, heat exchange box 30, etc., are correctly installed and firmly connected. Confirm that the heat exchange pipe 33 and its fins 331, spiral channel 322 and heat exchange chamber 34, etc. are in good condition. Check whether the levels of lubricating oil and heat exchange fluid are normal. When the agricultural machinery starts to operate, temperature sensor 10 will monitor the temperature of lubricating oil inside the gearbox in real time and continuously send temperature signals to control unit 20. Control unit 20 receives the data from temperature sensor 10 and analyzes and judges it according to the preset temperature threshold. These thresholds can be adjusted according to specific operating environments and needs. Once the detected lubricating oil temperature exceeds the set safety range, the control unit 20 will automatically trigger a cooling program. The working speed of the oil pump can be dynamically adjusted to more accurately control the flow rate and volume of the lubricating oil. Since the pipe diameter area S1 of the heat dissipation pipe 33 is twice the pipe diameter area S2 of the heat exchange pipe 341, the lubricating oil can maintain an appropriate flow rate while dissipating sufficient heat. In the heat exchange chamber 32, the lubricating oil and the heat exchange fluid exchange heat through the double-layer spiral channel 322. The heat exchange fluid enters the heat exchange chamber 34 through the heat exchange pipe 341, where it fully exchanges heat with the external environment or other cooling media. Finally, it is discharged from the system through the outlet pipe 321. During the operation of the agricultural machinery, the external airflow drives the fan blade 51 to rotate, and the fan blade 51 drives the gravity ball 52 on it to rotate together. Since the gravity ball 52 is flexibly connected by the spring 53, a dynamic balance between centrifugal force and elastic restoring force will be generated during the rotation, which will trigger periodic oscillation and rebound motion. These oscillation actions transmit local vibration to the area where the fan blade 51 is located, and further conduct it to the heat dissipation pipe 33 and its fins 331 surface. The vibration shakes off the dust, impurities and other debris attached to the surface of the fins 331, thereby achieving the purpose of automatic cleaning.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
