Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a hydraulic flip fan arrangement structure for a tractor and a tractor having the same. Background Art

[0002] The existing tractor products on the market are equipped with a variety of implements, with complex working conditions and a lot of dust and weeds. After the whole machine has been working for a period of time, there will be a lot of dust or weeds in front of the hood and the heat sink, which will reduce the cooling air intake and reduce the heat dissipation effect, affecting the heat dissipation performance of the engine. When the outlet temperature of the engine coolant reaches the torque limit temperature value set by the engine, the engine will reduce performance, affecting the normal operation of the whole machine, and it is necessary to stop the machine to maintain and clean the hood and heat sink, affecting the working efficiency.

[0003] In order to ensure the coolant outlet temperature requirement when the engine is working, some tractor products will extend the time for weed cleaning by increasing the size of the radiator core, but the larger core increases the design cost. Some tractor cooling packs will adopt a flip or push-pull structure, which has a complex structure, low cleaning efficiency, and inconvenient maintenance. The above methods all require shutdown for maintenance, affecting the user's operating efficiency. In general, the above technical means have the following obvious defects:

[0004] 1) Increasing the size of the heat dissipation core increases the design cost.

[0005] 2) The heat dissipation package flip structure has a complex structure and uses a gas spring or a slide rail structure, and its reliability is worse than that of a traditional mechanical structure.

[0006] 3) It is inconvenient to clean the heat dissipation pack after it is blocked.

[0007] 4) Frequent downtime for maintenance is required, resulting in low operating efficiency.

[0008] Based on this, it is necessary to develop a hydraulic flip fan arrangement structure for a tractor and a tractor having the same to overcome the above technical problems. Utility Model Content

The oil return port of the solenoid valve is connected to the hydraulic oil source through a hydraulic oil return pipe. The control switch is connected to a circuit between the solenoid valve and a power supply to control the on and off of the circuit.

[0012] The beneficial effects are: the structural design is simple and reasonable, and the angle of the fan blades can be rotated, thereby changing the wind direction of the fan.

The technology of hydraulic flip fan to clean the heat dissipation package and hood debris is realized, which can effectively solve the problem of high temperature of the whole machine caused by the hood and heat dissipation package being blocked by weeds, ensure the performance of the whole machine, save maintenance time, and improve work efficiency.

[0017] The beneficial effect of adopting the above further technical solution is: the chassis oil of the tractor is used as the hydraulic oil source, no additional hydraulic oil is needed, and the overall structural design is simplified.

[0018] Furthermore, it also includes a hydraulic pump, the inlet of the hydraulic pump is connected to the hydraulic oil source through a pipeline, and the outlet is connected to the oil inlet of the solenoid valve through a pipeline.

[0019] The beneficial effect of adopting the above further technical solution is that the design of the hydraulic pump can ensure good flow of hydraulic oil in the pipeline.

[0020] Furthermore, a filter is provided on the pipeline connected to the inlet of the hydraulic pump.

[0022] Furthermore, a pressure gauge is provided on the hydraulic pipeline.

[0023] The beneficial effect of adopting the above further technical solution is that the pressure on the hydraulic pipeline can be effectively detected by the pressure gauge, which makes it convenient for operators to know the circulation status of the hydraulic oil in the pipeline. If abnormal pressure occurs, it can be discovered and repaired in time.

[0024] Furthermore, the ports of the hydraulic pipeline and the hydraulic oil pipeline are connected via pipeline quick-connect joints.

[0037] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0038] Example 1

[0039] like Figure 1 and 2 As shown, the hydraulic flip fan arrangement structure for the tractor of this embodiment includes a hydraulic flip fan 1, a solenoid valve 3 and a control switch 4. The hydraulic flip fan 1 is installed in the tractor near the heat dissipation package. The oil inlet of the solenoid valve 3 is connected to the hydraulic oil source through a pipeline, the oil outlet of the solenoid valve 3 is connected to the hydraulic oil pipeline 11 of the hydraulic flip fan 1 through a hydraulic pipeline 6, the oil return port of the solenoid valve 3 is connected to the hydraulic oil source through a hydraulic return oil pipe 7, and the control switch 4 is connected to the circuit between the solenoid valve 3 and the power supply to control the on-off of the circuit.

[0040] The hydraulic flip fan arrangement structure for tractors of this embodiment is in normal operation. When the operation control switch 4 is operated to energize the solenoid valve 3 through the line, the hydraulic oil source enters the hydraulic flip fan 1 through the solenoid valve 3, the hydraulic pipeline 6, and the hydraulic oil pipeline 11 of the hydraulic flip fan 1. At this time, the hydraulic oil will overcome the return spring force inside the hydraulic flip fan 1 to flip the fan blades. Since the fan rotation direction remains unchanged, the fan blades flip to realize the fan from suction to blowing, thereby blowing away the sundries or dust adsorbed on the outside of the hood and the heat dissipation package. When the operation control switch 4 is powered off to stop the solenoid valve 3, the hydraulic pipeline 6 and the hydraulic oil pipeline 11 of the hydraulic flip fan 1 return to the hydraulic oil source through the hydraulic return oil pipe 7. At the same time, the fan blades of the hydraulic flip fan 1 flip back to their original position, and the fan returns to the initial state. In this way, a back-blowing maintenance process is completed. This process does not require shutdown. The control switch 4 can be operated at any time during the operation of the whole machine. The operation is simple, saving downtime maintenance time, and effectively improving the user's operating efficiency and operating benefits.

[0041] It should be noted that in the hydraulic flip fan arrangement structure for the tractor of this embodiment, the hydraulic flip fan 1 is a product of the prior art, and reference may be made to the fan involved in the patent technology with publication number CN212716862U.

[0042] In this embodiment, the control switch 4 is a mechanical push switch, which only needs to be pressed, and the operation is very convenient and quick.

[0043] In this embodiment, the hydraulic oil source comes from the oil in the chassis 5 of the tractor. When in use, there is no need to add other hydraulic oil sources, which simplifies the structural design of the tractor.

[0044] As a preferred embodiment, it further comprises a hydraulic pump 2, the inlet of the hydraulic pump 2 is connected to the hydraulic oil source through a pipeline, and the outlet is connected to the oil inlet of the solenoid valve 3 through a pipeline.

[0045] In the above embodiment, the design of the hydraulic pump 2 can provide the flow power of the oil, thereby ensuring the good flow of the oil in the pipeline.

[0046] As a preferred embodiment, a filter is provided on the pipeline connected to the inlet of the hydraulic pump 2.

[0047] In the above implementation scheme, the oil is filtered through a filter before entering the hydraulic pump 2 and the subsequent solenoid valve 3 to remove impurities, thereby ensuring the cleanliness of the oil entering the solenoid valve 3 and the fan, ensuring good performance of the two, and preventing the performance from being affected by the oil containing impurities or even causing failures during use.

[0048] In this embodiment, a pressure gauge is provided on the hydraulic pipeline 6. The pressure gauge can effectively detect the pressure on the hydraulic pipeline, so that the operator can know the flow status of the hydraulic oil in the pipeline, and can timely discover and repair any abnormal pressure.

[0049] In this embodiment, the ports of the hydraulic pipeline 6 and the hydraulic oil pipeline 11 are connected by pipeline quick-connect joints, which facilitates the rapid connection and separation of the two pipe ports.
