Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to an agricultural harvester dust cover, a cooling component and a harvester. Background Art

[0002] When harvesting crops such as corn using a harvester, the engine needs to be cooled by a cooling assembly consisting of an air duct, a radiator, and a dust hood. During the heat dissipation process of the radiator, a cooling medium (such as a connected water tank storing coolant) is used to dissipate heat, and the air duct blows cold air toward the engine. After being cooled by the radiator, the engine is cooled by air. The dust hood is installed on the side of the radiator away from the air duct to remove dust and prevent debris from entering the radiator. However, during long-term use, debris will enter the dust hood through the mesh of the dust hood, blocking the surface of the radiator and affecting the use of the radiator. After long-term operation, the radiator will become hot, the power performance will decrease, and the harvesting efficiency will decrease. Utility Model Content

[0015] The beneficial effect of adopting the above further solution is that the support plate can be removed from the dust cover box by removing the plug plate and disassembling the fixing plate.

[0016] Furthermore, the support plate and the plug plate are both vertically plugged into the dust cover box, and the lower end width of the plug plate is smaller than the upper end width, and the lower end of the plug plate is inserted into the dust cover box and pressed against the side wall of the other end of the support plate.

[0063] As a specific solution of the above embodiment, the cover plate 12 can be detachably connected to the main box body 11 by means of hinges, screws, etc.

[0064] Based on the above embodiment, a reinforcing plate 13 is fixed on the inner wall of the main box body 11 , and the reinforcing plate 13 is opposite to the mounting opening 111 , that is, fixed to the side of the main box body 11 where the air hole 3 is opened, so as to improve the structural strength of the main box body 11 .

[0067] The beneficial effect of adopting the preferred solution in the above embodiment is that the support plate 41 can be taken out from the dust cover box body 1 by removing the plug plate 43 and disassembling the fixing plate 42.

[0068] As a specific solution of the above embodiment, the cross section of the fixing plate 42 is L-shaped, and the two wing ends are detachably connected to the support plate 41 and the main box body 11 of the dust cover box body 1 through bolts (not shown in the figure).

[0069] Example 6

[0070] like Figures 2 to 6On the basis of embodiments 1-5, the support plate 41 and the plug plate 43 are both vertically plugged into the dust cover housing 1, and the lower end width of the plug plate 43 is smaller than the upper end width, and the lower end of the plug plate 43 is inserted into the dust cover housing 1 and pressed against the side wall of the other end of the support plate 41.

[0071] The beneficial effect of adopting the preferred scheme in the above embodiment is that by inserting the plug plate 43 downward into the dust cover box body 1, the support plate 41 can be limited and fixed to the dust cover box body 1 on the basis of the detachable connection between the fixing plate 42 and the lower end of the support plate 41, thereby keeping the support plate 41 fixed.

[0072] Based on the above embodiment, a rod hole 112 and a plug hole 113 that are interconnected are opened on the upper side of the main box body 11, and the support plate 41 can be made of square steel, adapted to and inserted in the rod hole 112, and the smaller end of the plug plate 43 is adapted to and inserted downward into the plug hole 113, and a limit is automatically formed through its larger end.

[0073] The rod hole 112 and the insertion hole 113 are interconnected, so that after the insertion plate 43 is taken out, the insertion hole 113 forms a take-out hole for taking out the support plate 41 , which is convenient for operation.

[0075] As a parallel solution of the above embodiment, the support plate 41 and the plug plate 43 can also be laterally plugged into the dust cover box 1, but in this case, the plug plate 43 may fall off the main box 11 due to mechanical shaking, resulting in unstable installation.

[0076] Based on the above embodiments.

[0077] Example 7

[0078] like Figure 1 and Figure 2 On the basis of embodiments 1-6, a plurality of mesh holes 2 are respectively opened on the side wall of the dust cover body 1 away from the air hole 3 and on the other side walls of the dust cover body 1.

[0079] The beneficial effect of adopting the preferred scheme in the above embodiment is that by covering the plurality of mesh holes 2, the ventilation area is increased, the air flow through the dust hood is improved, and the heat dissipation capacity of the radiator 7 is enhanced, thereby improving the operating efficiency of the harvesting machinery.

[0080] Example 8

[0081] like Figure 1 and Figure 2 , based on Example 1-7, mesh 2 is a regular hexagonal hole.

[0082] The beneficial effect of adopting the preferred scheme in the above embodiment is that while effectively blocking debris, the air inlet area relative to the circular hole is expanded. After the area is increased, the ventilation capacity of the mesh is enhanced, the heat dissipation capacity of the radiator will be improved, and the water tank will dissipate heat faster, thereby improving the efficiency of the harvesting machinery.

[0083] Based on the above embodiment, the diameter of the inscribed circle of the mesh 2 is 2.5 mm, the hole pitch is 3.5 mm, and the distribution angle is 120°.

[0084] Regular hexagonal holes are stronger: When building a structure with a regular hexagon, its sides support each other, which will better disperse the external force it is subjected to, and it has better strength than round holes or other shapes.

[0085] Regular hexagons use thinner plates: Since the regular hexagonal mesh has greater strength, there is no need to increase the thickness to maintain strength.

[0086] Regular hexagonal plates are lighter: Regular hexagonal plates are thin and have a larger punching rate, which can effectively reduce their own weight.

[0087] The regular hexagonal mesh is arranged very neatly, the six sides are closely arranged with the surrounding meshes, and the gaps are consistent, so its aesthetics can be greatly improved.

[0088] As a parallel solution of the above embodiment, the mesh 2 can also be a circular hole or other polygonal hole, but in this case, the heat dissipation area is smaller than that of the regular hexagonal hole.

[0089] In a second aspect, the utility model provides a cooling assembly, as described in detail below.

[0090] Example 9

[0091] like Figure 8 and Fig. 9 A cooling component includes an agricultural harvester dust cover as described in Examples 1-8, and also includes a radiator 7 and an air guide cover 8. The dust cover box 1 of the agricultural harvester dust cover is connected to the radiator 7 and communicated with the radiator 7 through the air hole 3, and the radiator 7 is connected and communicated with the air guide cover 8.

[0092] The beneficial effect of adopting the preferred scheme in the above embodiment is that, in the process of cooling the engine, the air guide cover 8 is started to rotate the fan inside the air guide cover 8, and the wind is blown into the main box 11 through the mesh 2, and blown to the radiator 7 through the wind hole 3. After being cooled by the radiator 7, it is blown out from the air guide cover 8 and blown to the engine to cool the engine; or when the fan inside the air guide cover 8 is rotated in the opposite direction, the heat generated by the engine is taken away by the fan, and after being cooled by the radiator 7, it is blown out from the mesh 2.

[0093] During the entire process of wind blowing, the blade 51 rotates to block the debris remaining in the wind to avoid clogging the surface of the radiator 7.

[0094] On the basis of the above-mentioned embodiment, a condenser 9 is installed between the main box body 11 and the radiator 7 to further cool the wind and improve the temperature reduction effect.

[0095] On the basis of the above-mentioned embodiment, the main box body 11 is installed with the condenser 9 by means of a plurality of hinges 91 on one side in the horizontal width direction, and is installed and fixed with the condenser 9 by means of a plurality of buckles 92 on the other side.
