Description

Technical Field

[0001] The utility model relates to the field of radiator auxiliary equipment, in particular to a multi-faceted air inlet filter screen for a tractor radiator. Background Art

[0002] During the working process of a tractor, a large amount of heat is generated in the water tank, and this heat needs to be dissipated in time to ensure the normal operation of the tractor. Therefore, a radiator is installed on the front bumper of the tractor. In order to quickly release the heat in the radiator, a filter screen is usually set outside the radiator, which can not only meet the heat dissipation needs but also protect the radiator itself. Even some radiators are provided with multi-faceted filter screens outside to enable the radiator to fully exchange heat with the outside. For example, the radiator with the publication number CN116576011A and the name of a radiator for a tractor has three filter screens arranged on the installation frame. One filter screen blocks dust on the front side of the installation plate, and the other filter screen blocks dust at the ventilation opening of the positioning frame. However, after the filter screen is used for a long time, a large amount of dust or large-diameter particles will adhere to its surface, which will affect the smoothness of the filter screen and further reduce the heat exchange efficiency between the radiator and the outside. Therefore, it is necessary to clean the filter screen regularly. When cleaning the filter screen of the above radiator, the tractor needs to stop working. After the personnel disassemble and wash the filter screen and reinstall it, the tractor can operate normally. This is equivalent to the tractor needing to stop for maintenance and cannot be maintained without stopping, which is not user-friendly for the use of the tractor. Based on this, the present utility model is proposed. Summary of the Utility Model

[0003] In order to solve the technical problems existing in the above-mentioned prior art, the present utility model provides a multi-faceted air inlet filter screen for a tractor radiator.

[0004] To achieve the above object, the present utility model provides the following technical solution: A multi-faceted air inlet filter screen for a tractor radiator includes two first installation frames arranged in parallel and having the same specifications. One end of the two first installation frames facing each other is fixedly connected. A first filter screen is detachably installed inside each first installation frame. The other ends of the two first installation frames away from each other are respectively fixedly connected to second installation frames. A second filter screen is detachably installed inside each second installation frame. Sealing members are arranged inside both the first installation frame and the second installation frame. When the first filter screen is removed, the sealing member inside the first installation frame acts to block the filtering area of the first filter screen. When the second filter screen is removed, the sealing member inside the second installation frame acts to block the filtering area of the second filter screen.

[0005] Preferably, a filter screen receiving groove for placing the first filter screen is formed inside the first installation frame. On the side of the first installation frame facing the radiator, several first rotating plates with the same specifications are distributed from top to bottom in sequence. Both ends of each first rotating plate are rotatably connected to the first installation frame. When the first filter screen is installed inside the first installation frame, all the first rotating plates are in a horizontal state. When all the first rotating plates rotate relative to the first installation frame to a vertical state, every two adjacent first rotating plates are in contact with each other.

[0006] Preferably, limiting plug plates are respectively fixed to the top and bottom inside the first installation frame. When all the first rotating plates rotate to a vertical state, the topmost and bottommost first rotating plates are respectively in contact with the plate surfaces of the two limiting plug plates. The several first rotating plates and the two limiting plug plates form a sealing member.

[0007] Preferably, when the first filter screen is taken out from the first installation frame, all the first rotating plates rotate from a horizontal state to a vertical state in sequence.

[0008] Preferably, gear cavities are integrally formed on both sides of the first installation frame. A central shaft is fixedly connected to the middle of each first rotating plate.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Usually, the components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but only represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Such as Figures 1-5As shown in the figure, this embodiment proposes a multi-sided air intake filter screen for a tractor radiator, which includes two first mounting frames 1 arranged in parallel and having the same specifications. One end of the two first mounting frames 1 facing each other is fixedly connected. A first filter screen 3 is detachably installed inside each first mounting frame 1. The other ends of the two first mounting frames 1 away from each other are respectively fixedly connected to second mounting frames 2, and the specifications of the two second mounting frames 2 are also the same. A second filter screen 4 is detachably installed inside each second mounting frame 2. In this way, the entire filter screen is composed of two first filter screens 3 and two second filter screens 4.

[0022] Under normal circumstances, the heat of the radiator will be dissipated from the first filter screen 3 and the second filter screen 4. However, since the radiator is installed on the front bumper of the tractor, and during the walking process of the tractor, because the two first filter screens 3 face the walking direction of the tractor, the external air will flow relative to the radiator. That is, during the walking process of the tractor, the external air enters the inside of the first mounting frame 1 from the first filter screen 3 to contact the radiator for heat exchange, and then flows out from the second filter screen 4. Sealing members are provided inside both the first mounting frame 1 and the second mounting frame 2. When the first filter screen 3 and the second filter screen 4 need to be removed and cleaned, the corresponding sealing members will act to completely seal the filtering areas of the first filter screen 3 or the second filter screen 4, preventing external dust or large-diameter particles from entering the radiator after the first filter screen 3 and the second filter screen 4 are removed. However, in order not to affect the normal operation of the tractor, the best way is to select one set of the first filter screen 3 and the second filter screen 4 for removal and cleaning, and the other set continues to work. In this way, the heat of the radiator can be exchanged with the outside, and the normal operation of the tractor is not affected.

[0023] As a preferred embodiment, for the combined removal and cleaning of the second filter screen 4 and the first filter screen 3, in order to enable the external air to exchange heat with the radiator to the greatest extent, the second filter screen 4 farther away from the first filter screen 3 is selected for removal together. For the sake of easy understanding, Figure 1 taking it as an example, when the first filter screen 3 inside the left first mounting frame 1 is removed, then the second filter screen 4 inside the second mounting frame 2 fixedly connected to the other first mounting frame 1 is removed. This can extend the flow path of the air inside the radiator and ensure the heat exchange efficiency.

[0024] In the above solution, for the plugging members inside the first mounting frame 1 and the second mounting frame 2, all four plugging members are the same in structure. Only the widths of the first mounting frame 1 and the second mounting frame 2 are different. Therefore, the specifications of the plugging members provided inside the first mounting frame 1 and the second mounting frame 2 are different, but the structures and working principles are all the same. Taking the plugging member inside the first mounting frame 1 as an example for specific and detailed description: A filter screen accommodating groove 10 for accommodating the first filter screen 3 is formed inside the first mounting frame 1. The notch of the first mounting frame 1 also exactly matches the filtering area of the first filter screen 3. Several first rotating plates 6 with the same specifications are distributed in sequence from top to bottom on the side of the first mounting frame 1 facing the radiator. Both ends of each first rotating plate 6 are rotatably connected to the first mounting frame 1. When the first filter screen 3 is installed inside the first mounting frame 1, all the first rotating plates 6 are in a horizontal state and will not affect the entry of external air into the first mounting frame 1. When it is necessary to remove the first filter screen 3, all the first rotating plates 6 can rotate relative to the first mounting frame 1 to a vertical state, and every two adjacent first rotating plates 6 can also be in contact with each other to avoid generating gaps. At the same time, limiting plugging plates 5 are respectively fixed to the top and bottom inside the first mounting frame 1. When the uppermost first rotating plate 6 rotates to a vertical state, it cooperates with the limiting plugging plate 5 to form a plugging for external air. The same principle applies to the limiting plugging plate 5 at the bottom and the lowermost first rotating plate 6.

[0025] Gear cavities 12 are integrally formed on both sides of the first mounting frame 1. A central shaft is fixedly connected to the middle of each first rotating plate 6. Through holes 11 are provided on the outer wall of the gear cavity 12 corresponding to both ends of each central shaft. Both ends of each central shaft penetrate through the corresponding through holes 11 and extend into the gear cavity 12 and are respectively fixedly sleeved with gears 13. Linear racks 9 are fixedly installed along the vertical direction at the bottoms on both sides of the first filter screen 3. A handle 8 is connected to the top of the first filter screen 3. When a person removes the first filter screen 3 from the first mounting frame 1 through the handle 8, the linear racks 9 on both sides of the first filter screen 3 are respectively engaged with each gear 13 in sequence. By controlling the length of the linear racks 9, when the linear racks 9 are respectively engaged with each gear 13, each gear 13 can be driven to exactly rotate 90°. In this way, when the first filter screen 3 is completely separated from the first mounting frame 1, all the first rotating plates 6 are in a vertical state and cooperate with the two limiting plugging plates 5 to form a plugging. When the first filter screen 3 is put back inside the first mounting frame 1 after being cleaned, all the first rotating plates 6 can rotate back to a horizontal state again.
