Description

Technical Field

[0001] The utility model relates to the field of graders, in particular to a grader protective cover. Background Art

[0002] For high-horsepower graders, their engines will generate more heat when working. When the conventional cooling system cools the engine, part of the heat from the engine will invade the space of the cooling system, affecting the cooling effect of the engine. For example, the hot air generated by the engine will be sucked into the cooling system and participate in the heat dissipation of the cooling pipe, but the temperature of this part of the air is too high, affecting the heat dissipation efficiency of the cooling system.

[0003] In summary, how to improve the engine heat dissipation efficiency of a high-horsepower grader has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to improve the heat dissipation efficiency of the engine of a high-horsepower grader;

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The utility model is a grader cover, comprising: a cover body, a partition plate is arranged inside the cover body, and the cover body is divided into a first cavity for placing an engine and a second cavity for placing a cooling system; the partition plate prevents the heat in the first cavity from being transferred to the second cavity; an air inlet net is arranged in the second cavity and on the outer wall of the cover body; an air outlet grille is arranged on the side of the rear of the cover body;

[0007] In this solution, a partition is provided in the cover body, and the cover body is divided into a first cavity for placing the engine and a second cavity for placing the cooling system. Due to the presence of the partition, the heat generated by the engine will be blocked, and the heat that can be transferred to the second cavity will be greatly reduced. The central fan of the cooling system rotates, sucking air from the air inlet net, and discharged from the air outlet grille after heat exchange through the cooling pipe. The sucked air will not be disturbed by the engine heat, and the temperature is relatively low, thereby improving the engine cooling efficiency of the high-horsepower grader.

[0008] In order to explain how the partition is installed in the housing, the utility model adopts flanges on the top and both sides of the partition; bolts pass through the flanges and the housing to fix the partition and the housing;

[0009] The three sides of the partition are provided with flanges, and bolts pass through the flanges and the cover body to fix the partition and the cover body together.

[0010] In order to increase the connection strength of the partition and prevent deformation, the utility model uses the middle part of the partition to be recessed inward, and the middle part of the partition is formed into a concave part and flat parts on both sides of the concave part;

[0011] The two sides of the partition are flat parts, and the middle is a concave part, so that the partition is not a flat structure, which increases the connection strength of the partition.

[0012] Due to the operation of the engine and the fan and the inhalation of air into the second cavity, the partition plate will shake due to the change of external force and generate noise. In order to avoid this noise source, the utility model adopts a plurality of parallel reinforcing ribs arranged in the concave portion;

[0013] By providing reinforcing ribs, the connection strength of the recessed portion can be enhanced and shaking will not occur. The three sides of the planar portion are provided with flanges to avoid shaking of the planar portion, thereby preventing noise from being generated due to shaking of the partition.

[0014] In order to achieve the connection of the heat dissipation pipes on the partition, the utility model adopts a plurality of holes for the heat dissipation pipes to pass through the partition;

[0015] The radiator pipe passes through the hole body to connect the cooling pipeline of the engine and the radiator pipe of the cooling system.

[0016] In order to avoid setting the reinforcing ribs, thereby affecting the internal space of the first cavity, the utility model adopts the arrangement that the top surface of the reinforcing ribs is flush with the horizontal plane;

[0017] In this way, the reinforcing ribs will not invade the space of the first cavity and will not affect the internal space of the first cavity.

[0018] The beneficial effects of the utility model are as follows: the utility model is a grader cover, in which a partition is arranged inside the cover, and the cover is divided into a first cavity for placing the engine and a second cavity for placing the cooling system. Due to the presence of the partition, the heat generated by the engine will be blocked, and the heat that can be transferred to the second cavity will be greatly reduced. The middle fan of the cooling system rotates, sucking air from the air inlet net, and discharged from the air outlet grille after heat exchange through the cooling pipe. The sucked air will not be disturbed by the engine heat, and the temperature is relatively low, thereby improving the engine cooling efficiency of the high-horsepower grader.

[0025] like Figure 1-2 As shown, the utility model is a grader cover, comprising: a cover body 1, a partition 2 is arranged inside the cover body 1, and the cover body 1 is divided into a first cavity 3 for placing an engine and a second cavity 4 for placing a cooling system; the partition 2 prevents the heat in the first cavity 3 from being transferred to the second cavity 4; an air inlet net 5 is arranged in the second cavity 4 and on the outer wall of the cover body 1; an air outlet grille 6 is arranged on the side of the rear end of the cover body 1;

[0026] In this solution, a partition is provided in the cover body, and the cover body is divided into a first cavity for placing the engine and a second cavity for placing the cooling system. Due to the presence of the partition, the heat generated by the engine will be blocked, and the heat that can be transferred to the second cavity will be greatly reduced. The central fan of the cooling system rotates, sucking air from the air inlet net, and discharged from the air outlet grille after heat exchange through the cooling pipe. The sucked air will not be disturbed by the engine heat, and the temperature is relatively low, thereby improving the engine cooling efficiency of the high-horsepower grader.

[0027] like Figure 3 As shown, in order to illustrate how the partition is installed in the housing, the utility model adopts a partition 2 with flanges 7 on the top and both sides; bolts pass through the flanges 7 and the housing 1 to fix the partition 2 and the housing 1;

[0028] The three sides of the partition are provided with flanges, and bolts pass through the flanges and the cover body to fix the partition and the cover body together.

[0029] like Figure 3 As shown, in order to increase the connection strength of the partition and prevent deformation, the utility model uses the middle part of the partition 2 to be recessed inward, and the middle part of the partition 2 forms a recessed portion 8 and flat portions 9 located on both sides of the recessed portion 8;

[0030] The two sides of the partition are flat parts, and the middle is a concave part, so that the partition is not a flat structure, which increases the connection strength of the partition.

[0031] like Figure 3As shown, due to the operation of the engine and the fan and the suction of air into the second cavity, the partition will shake due to the change of external force and generate noise. In order to avoid this noise source, the utility model adopts a plurality of parallel reinforcing ribs 10 arranged in the recessed portion 8;

[0032] By providing reinforcing ribs, the connection strength of the recessed portion can be enhanced and shaking will not occur. The three sides of the planar portion are provided with flanges to avoid shaking of the planar portion, thereby preventing noise from being generated due to shaking of the partition.

[0033] like Figure 3 As shown, in order to achieve the connection of the heat dissipation pipes on the partition, the utility model adopts a plurality of holes 11 for the heat dissipation pipes to pass through the partition 2;

[0034] The radiator pipe passes through the hole body to connect the cooling pipeline of the engine and the radiator pipe of the cooling system.

[0035] like Figure 3 As shown, in order to avoid setting the reinforcing ribs and thus affecting the internal space of the first cavity, the utility model adopts that the top surface of the reinforcing ribs 10 is set flush with the horizontal plane 9;

[0036] In this way, the reinforcing ribs will not invade the space of the first cavity and will not affect the internal space of the first cavity.
