DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0033] The heat dissipation fin 1 is fixedly installed on the casing structure, the heat dissipation fin 1 one side is fixedly connected with the partition 9, is set up with multiple through -holes on the partition 9, and the through -hole is set in the way of inclined downward, and the inclined through -hole will make the flowing direction of the air entering change, and the straw debris will be impacted and falls down under the action of inertia with the side wall of the through -hole, and the straw debris entering into the heat dissipation fin 1 with the air is reduced.

[0034] The heat dissipation fin 1 is fixedly connected with the mounting seat 2 on the side near the partition 9, and the mounting seat 2 is set up as the cavity structure with the opening on one side, and the scraper 10 is slidably connected in the mounting seat 2, and the side wall of the scraper 10 is tightly attached to the inner side wall of the mounting seat 2, and the scraper 10 can clean the adhered straw debris on one side of the heat dissipation fin 1 when sliding in the fixed seat.

[0035] A through hole is provided on the inner top wall of the mounting base 2, and a hydraulic motor 7 is fixedly connected to the top of the mounting base 2. A screw rod 11 is fixedly connected to the through hole at the driving end of the hydraulic motor 7, and the screw rod 11 is threadedly connected to the inside of the scraper 10. A pipe 6 is connected to one side of the hydraulic motor 7, and one end of the pipe 6 is connected to the oil tank 5. The oil tank 5 is fixed to the shell structure by bolts. The outside of the end of the pipe 6 close to the hydraulic motor 7 is connected to the electromagnetic reversing valve 3 (the electromagnetic reversing valve 3 uses the electromagnetic reversing valve 3 of model WE10, and other models can also be used, as long as the reversal of the hydraulic oil inside the hydraulic motor 7 can be achieved) the outside of the end of the pipe 6 close to the oil tank 5 is connected to the hydraulic pump 4.

[0036] When straw debris adheres to the surface of the partition 9 on one side of the heat dissipating fin 1 due to the flow of air, the hydraulic pump 4 is started to transport the hydraulic oil in the oil tank 5 to the inside of the hydraulic motor 7, driving the hydraulic motor 7 to drive the screw rod 11 to rotate. When the screw rod 11 rotates, it pushes the scraper 10 to move downward inside the mounting seat 2. When the scraper 10 moves to the bottom of the mounting seat 2, the electromagnetic reversing valve 3 is started to change the direction of flow of the hydraulic oil when it enters the hydraulic motor 7, so that the hydraulic motor 7 drives the screw rod 11 to rotate in the opposite direction, pushing the scraper 10 to move upward inside the mounting seat 2, and causing the scraper 10 to reciprocate inside the mounting seat 2, thereby cleaning the straw debris on the surface of the partition 9.

[0037] A collecting bin 15 is fixedly connected to the bottom of the opening side of the mounting base 2 , and notches are provided on both the front and rear sides of the inner sidewalls of the collecting bin 15 so that the baffle 14 can enter the interior of the collecting bin 15 when moving downward.

[0038] A cross bar 13 is fixedly connected to the inside of the collection bin 15, a rotating shaft is fixedly connected to the top of the side wall of the collection bin 15, a baffle 14 is rotatably connected to the outside of the rotating shaft, one side of the baffle 14 extends to the bottom of the cross bar 13, and a torsion spring 12 is wrapped around the outside of both ends of the rotating shaft. One end of the torsion spring 12 is fixedly connected to the inner wall of the collection bin 15, and the other end of the torsion spring 12 extends to the bottom of the baffle 14.

[0039] When the scraper 10 moves downward inside the mounting base 2, it pushes the baffle 14 to rotate downward so that the scraper 10 can enter the collecting bin 15 and contact the cross bar 13, so that when the scraper 10 moves inside the collecting bin 15, the cross bar 13 can scrape the straw debris on the scraper 10 off and drop it into the collecting bin 15. When the scraper 10 moves upward, it will cancel the pressure on the baffle 14, and the torsion spring 12 will push the baffle 14 to rotate upward due to its own elastic force, covering the top opening of the collecting bin 15 to prevent the straw debris inside the collecting bin 15 from floating in the air.

[0040] The oil tank 5 is communicated with the oil return pipe 8 outside, and the middle part of the oil return pipe 8 is fixedly connected in the heat dissipation fin 1 in an S shape. The S-shaped oil return pipe 8 can increase the flow path of the hydraulic oil in the middle part of the oil return pipe 8, prolong the heat exchange time of the hydraulic oil and the air, and improve the cooling effect of the hydraulic oil.

[0041] The other end of the oil return pipe 8 extends out of the inside of the heat dissipation fin 1. The end of the heat dissipation fin 1 away from the mounting base 2 is fixedly connected with a fan 16. When the hydraulic oil at a higher temperature enters the inside of the oil return pipe 8, it will flow in the oil return pipe 8. When the hydraulic oil flows to the middle part of the oil return pipe 8, the fan 16 is started to suck the air on one side of the heat dissipation fin 1 to pass through the heat dissipation fin 1, so that the hydraulic oil in the oil return pipe 8 exchanges heat with the flowing air through the inner side wall of the oil return pipe 8 and the heat dissipation fin 1, and the hydraulic oil in the oil return pipe 8 is cooled. After the hydraulic oil is cooled, it will flow from the oil return pipe 8 into the oil tank 5 for storage.

[0042] The other end of the oil return pipe 8 extends out of the inside of the heat dissipation fin 1. The end of the heat dissipation fin 1 away from the mounting base 2 is fixedly connected with a fan 16. When the hydraulic oil at a higher temperature enters the inside of the oil return pipe 8, it will flow in the oil return pipe 8. When the hydraulic oil flows to the middle part of the oil return pipe 8, the fan 16 is started to suck the air on one side of the heat dissipation fin 1 to pass through the heat dissipation fin 1, so that the hydraulic oil in the oil return pipe 8 exchanges heat with the flowing air through the inner side wall of the oil return pipe 8 and the heat dissipation fin 1, and the hydraulic oil in the oil return pipe 8 is cooled. After the hydraulic oil is cooled, it will flow from the oil return pipe 8 into the oil tank 5 for storage.

[0043] When the baffle 9 filters the straw debris mixed in the air, the hydraulic pump 4 is started to deliver the hydraulic oil to the inside of the hydraulic motor 7 to drive the hydraulic motor 7 to rotate the lead screw 11. When the lead screw 11 rotates, it pushes the scraper 10 to move downward in the mounting base 2. The electromagnetic reversing valve 3 (the electromagnetic reversing valve 3 is powered by a storage battery) is started to work to change the flow direction of the hydraulic oil, so that the hydraulic motor 7 drives the lead screw 11 to rotate in the opposite direction to push the scraper 10 to move upward in the mounting base 2. The scraper 10 reciprocates in the mounting base 2 to clean the straw debris on the surface of the baffle 9 to prevent the straw debris from blocking the gaps between the heat dissipation fins 1.

[0044] When the scraper 10 moves downward in the mounting base 2, it pushes the baffle 14 to rotate downward to make the scraper 10 enter the inside of the collecting bin 15. During the process of entering the inside of the collecting bin 15, the cross rod 13 scrapes off the straw debris attached to the scraper 10 and falls into the collecting bin 15 for storage. When the scraper 10 moves upward in the mounting base 2, the pressing on the baffle 14 is released. At this time, the torsional spring 12 pushes the baffle 14 to rotate upward to cover the top opening of the collecting bin 15 to prevent the straw debris from flying out of the collecting bin 15.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
