Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery cooler technology, specifically a dustproof net for agricultural machinery that is easy to disassemble. Background Technology
[0002] The cooling module of an agricultural tractor includes a water tank and an intercooler and hydraulic oil cooler mounted on one side of the water tank. However, due to the harsh working environment and the fact that the water tank, intercooler, and hydraulic oil cooler are combined into one unit, over time weeds, fallen leaves, and dust can get into the gaps between them, causing blockages. Since tractors rely entirely on the engine to drive a fan for cooling, significant blockages can impede airflow, eventually leading to cooling module failure and overheating. Therefore, rigid dust screens are usually installed at the front and rear of the radiator. This prevents impurities from adhering to the dust screens and getting onto the radiator core. After work, the dust screens are removed, cleaned, and then reinstalled. This method satisfies ventilation needs while preventing impurities from sticking to the radiator core and causing overheating. However, with the emergence of power-shift and CVT products in agricultural machinery, the front heat dissipation components have become more numerous and larger, and the piping has also increased accordingly. Removing rigid dust filters often presents significant difficulties, or even makes them impossible, due to their tight fit with the heat dissipation components and piping, or space constraints. This not only inconveniences the daily maintenance and cleaning of agricultural machinery but may also affect heat dissipation efficiency due to the long-term accumulation of dust and dirt, thereby impacting the overall performance and lifespan of the agricultural machinery. Utility Model Content
[0003] To address the technical problems mentioned above, this utility model provides a dustproof net for agricultural machinery that is easy to disassemble.
[0004] The technical solution of this utility model is as follows: A dustproof net for agricultural machinery that is easy to disassemble includes a water tank and a cooler assembly installed in front of the water tank. The cooler assembly includes an intercooler and a hydraulic oil cooler. The dustproof net assembly is provided on both the side of the cooler assembly closest to and furthest from the water tank. The dustproof net assembly includes a frame-shaped bracket with a flexible woven net installed in the middle of the bracket, and the woven net can cover the front and rear end faces of the cooler assembly. The upper end of the bracket is provided with a hanging ring assembly, and the upper end of the water tank and the upper front side of the cooler assembly are both provided with hooks for attaching the hanging ring assembly.
[0005] To improve the stability of the dustproof net assembly and ensure the dustproof effect, the hanger is equipped with hanging spring assemblies on both sides near the bottom of the hanger, and the bottom of the water tank and the bottom of the cooler are equipped with hanging rings for hanging the hanging spring assemblies.
[0006] The specific design of the hanging ring assembly is as follows: the hanging ring assembly includes a connector that connects to the hanger, and the upper end of the connector is provided with a through opening. A hanging ring is provided inside the through opening, and the hanging nose is designed as an L-shape with the opening facing upwards. The hanging ring can be hooked onto the opening of the hanging nose.
[0007] To accommodate the shape of the cooler assembly and avoid taking up additional space, the bracket is designed as a rectangular frame.
[0008] In order to reduce the entry of debris into the intercooler and hydraulic oil cooler, and to facilitate the replacement of woven mesh in different areas, a horizontal partition plate is set in the middle of the bracket, and the partition plate is located in the middle position between the intercooler and the hydraulic oil cooler.
[0009] To accommodate the shape of the hydraulic oil cooler and allow the bracket to avoid the inlet and outlet ports of the hydraulic oil cooler, the bracket has arc-shaped openings on both sides, located near the hydraulic oil cooler and facing outwards.
[0010] Furthermore, the woven mesh is made of nylon.
[0011] To ensure the rigidity of the bracket, steel wires are embedded in both the upper and lower ends of the bracket along the length direction.
[0012] To facilitate the separation of the cooler assembly from the water tank and the installation and removal of the inner dustproof mesh assembly, the upper surface of the cooler assembly is hinged to the upper surface of the water tank.
[0013] To facilitate the fixing of the cooler assembly and the water tank, the cooler assembly is provided with a side plate on its side, and a connecting plate extends outward from the side plate. The water tank is equipped with a mounting bracket, and a hammer nut is provided inside the mounting bracket. The cooler assembly and the water tank are fixed by connecting the connecting plate and the hammer nut through eye bolts.
[0014] The beneficial effects of this utility model are as follows: This utility model is a dustproof net for agricultural machinery that is easy to disassemble. Compared with the defects of traditional rigid dustproof nets, which are difficult to disassemble due to tight fit with heat dissipation components and pipes or space constraints, resulting in the accumulation of impurities and affecting heat dissipation, this dustproof net uses a flexible woven net of nylon material for the dustproof net assembly. It can flexibly deform with the hanging frame, avoiding rigid interference with complex pipes and newly added heat dissipation components. The hanging ring assembly at the upper end of the hanging frame is engaged with the hanging nose of the equipment, and the bottom end is connected to the hanging ring through the hanging spring assembly. When disassembling, it can be quickly removed by simply releasing the fixing of the hanging ring and the hanging spring without additional tools. This completely solves the problem of obstructed disassembly of rigid dustproof nets, greatly reduces the difficulty and time of daily maintenance, ensures that impurities can be cleaned in time, and ensures smooth airflow of the heat dissipation module. The hinge connection design between the cooler assembly and the water tank facilitates the separation of the cooler assembly from the water tank, thereby ensuring the installation and disassembly of the inner dustproof net assembly. When deep maintenance is required, the cooler assembly can be opened, and with the convenient disassembly of the dustproof net, the heat dissipation module can be cleaned in all directions.

[0017] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.
[0018] Example This embodiment provides a dustproof net for agricultural machinery that is easy to disassemble. See [link / reference]. Figure 1 This system aims to solve the problem of difficult disassembly caused by the increased number of heat dissipation components and dense piping in agricultural machinery using traditional rigid dust nets. Through the flexible woven mesh 32 and the frame design that can be quickly attached, the dust net can be easily disassembled and efficiently cleaned. It is compatible with agricultural machinery such as tractors equipped with power shift and CVT systems, ensuring the long-term stable operation of the heat dissipation module. Its specific structure is as follows: The dust net system is based on the tractor's water tank 1 and cooler assembly 2. The cooler assembly 2 includes an intercooler 21 and a hydraulic oil cooler 22 arranged in parallel. The two are fixedly connected as a whole and fixed to each other by a side plate 8. It is installed on the front side of the water tank 1 and together constitutes the core heat dissipation module of the tractor. To achieve flexible linkage between the cooler assembly 2 and the water tank 1, the upper surface of the cooler assembly 2 and the upper surface of the water tank 1 are hinged together by a hinge 7. The cooler assembly 2 can be flipped upward around the hinge 7 to further expand the maintenance and operation space. The side plate 8 extends outward with a connecting plate 9 with through holes. The corresponding side of the water tank 1 is fixedly installed with a mounting bracket 10 by bolts. A hammer nut 11, which is a metal block with internal threads, is welded and fixed inside the mounting bracket 10. During assembly, the cooler assembly 2 and the water tank 1 are firmly fixed by threading the eye bolt 12 through the through hole of the connecting plate 9. The fixation can be released by unscrewing the eye bolt 12, which makes it easy to flip the cooler assembly 2.
[0019] To completely prevent impurities from entering the heat dissipation gap, dustproof net assemblies 3 are installed on both the side of the cooler assembly 2 closest to the water tank 1 and the side furthest from the water tank 1. Both sets of dustproof net assemblies 3 have identical structures, using a rectangular frame-shaped bracket 31 as the supporting framework. Fine steel wires 38 are embedded along the length of both the upper and lower ends of the bracket 31, ensuring the overall structural rigidity of the bracket 31 and preventing the flexible net from sagging, while also avoiding the difficulty of adapting to complex spaces as with a fully rigid frame. A flexible woven mesh 32 is installed in the middle of the bracket 31. The woven mesh 32 is made of nylon, possessing excellent wear resistance, aging resistance, and breathability. The mesh size is set at 0.5-1mm, effectively blocking impurities such as weeds, fallen leaves, and dust, without affecting the fan's air intake and heat dissipation. The area of the woven mesh 32 is slightly larger than the end face area of the cooler assembly 2, ensuring complete coverage of the front and rear ends of the intermediate cooler 21 and the hydraulic oil cooler 22.
[0020] For the parallel arrangement of the intercooler 21 and the hydraulic oil cooler 22, the bracket 31 has a horizontally integrally formed partition plate 36 in the middle. The height of the partition plate 36 is the same as that of the bracket 31, and its width matches the gap between the two coolers. It is located precisely in the middle of the intercooler 21 and the hydraulic oil cooler 22, which can divide the woven mesh 32 into two independent areas, each corresponding to one of the two coolers, to prevent impurities from seeping in through the gap between the two coolers. At the same time, the bracket 31 has arc-shaped openings 37 formed on both sides. The arc-shaped openings 37 are located on the part of the bracket 31 closest to the hydraulic oil cooler 22, and the openings face outwards. Their curvature matches the diameter of the inlet and outlet oil pipes on the outside of the hydraulic oil cooler 22, which can avoid dense pipes and solve the problem of interference between traditional dustproof nets and pipes, ensuring that the bracket 31 can be installed smoothly.
[0021] It should be noted that, because the cooler assembly 2 has inlet and outlet ports on its outer side, an arc-shaped opening 37 needs to be provided to avoid them, and an isolation plate 36 needs to be provided to protect the outer side, such as... Figure 1 and Figure 3 As shown, however, the dust filter assembly 3 inside the cooler assembly 2 does not need to avoid other components, and being inside, it does not need to protect the space between the two coolers. Therefore, as Figure 5 As shown, the inner dustproof mesh assembly 3 does not need to have an arc-shaped opening 37 and there is no need to install an isolation plate 36. The dustproof net assembly 3 is quickly fixed to the water tank 1 and the cooler assembly 2 through a hook-and-loop structure. The hook-and-loop structure consists of two parts: the upper hook ring assembly and the lower hook spring assembly 5, ensuring stable installation and convenient disassembly. The hook ring assembly includes hook rings 35 fixed to both ends of the upper surface of the bracket 31. It is a closed circular ring structure. Correspondingly, the upper surface of the water tank 1 and the upper front surface of the cooler assembly 2 are welded with L-shaped hooks 4 with upward openings. The hooks 4 are made of bent round steel, which is reliable in strength. The hook rings 35 can be directly hooked onto the opening of the hooks 4 to achieve upper positioning of the dustproof net assembly 3.
[0022] Hanging spring assemblies 5 are provided on both sides near the bottom of the bracket 31. Suitable existing parts can be purchased. The bottom of the water tank 1 and the bottom of the cooler assembly 2 are provided with lifting rings 6 for hanging the hanging spring assemblies 5. The lifting rings 6 are closed structures. When hanging, the hanging spring assemblies 5 are put into the lifting rings 6 to complete the lower end fixation. The cooperation between the hanging spring assemblies 5 and the lifting rings 6 not only makes the installation convenient, but also can adapt to the slight displacement of the bracket 31 in the vibration environment, avoiding structural damage caused by rigid connection.
[0023] When cleaning the dust screen after agricultural machinery operation, the disassembly process is extremely convenient: To clean only the outer dust screen, simply separate the hanging spring assembly 5 from the lifting ring 6, then lift the bracket 31 upwards to disengage the upper hanging ring from the lug 4, and the outer dust screen can be removed. To clean the inner dust screen or perform deep maintenance on the heat dissipation module, first unscrew the lifting ring screw 12, then rotate the cooler assembly 2 upwards around the hinge 7 to a suitable angle, and then remove the inner dust screen following the same steps. During cleaning, simply shake the dust screen assembly 3 or use a high-pressure air gun to blow away impurities from the nylon woven mesh 32. After cleaning, reassemble in reverse order.
