Description

Technical Field

[0001] The present application belongs to the technical field of bulldozers, and in particular relates to a coal-pushing heat dissipation structure for a bulldozer. Background Art

[0002] Currently, the ventilation grilles of bulldozers are of grille type and circular hole type. When the bulldozer is doing bulldozing operations, these two types of ventilation grilles cannot prevent gangue particles from entering through the gaps, causing the fan to collide with the gangue, and then causing the gangue to hit the radiator and damage the radiator. Utility Model Content

[0003] In order to solve the technical problem in the prior art that when a bulldozer is pushing coal, gangue particles enter through the gaps in the ventilation grille, causing the fan to hit the gangue and affecting the heat dissipation of the bulldozer, the present application provides a coal pushing type heat dissipation structure for a bulldozer.

[0004] A coal-pushing type heat dissipation structure for a bulldozer includes a front hood and a protective assembly. The protective assembly is installed at the opening of the front hood, and there is a gap between the protective assembly and the bottom of the opening of the front hood. The protective assembly includes a ventilation grille and a protective net. The protective net is fixedly installed on the outside of the ventilation grille, and the bottom of the protective net and the bottom of the ventilation grille are separated from each other to form an ash discharge port.

[0005] As an embodiment, the protection assembly further includes gaskets, which are arranged at the upper edge, left edge and right edge between the ventilation grille and the protection net.

[0006] As another embodiment, the bottom of the protective net has a protrusion protruding toward a side away from the ventilation grille, and the protrusion and the bottom of the ventilation grille form the ash discharge port.

[0007] Specifically, the protective net includes a frame and a mesh plate, the frame is fixed to the edge of the mesh plate, the ventilation grille includes a main structure and ventilation holes arranged on the main structure, and the mesh size on the mesh plate is smaller than the size of the ventilation holes.

[0008] In one embodiment, the ventilation grille is fixedly connected to the edge of the protective net by bolts.

[0009] Specifically, one side of the protection component is rotatably connected to the front hood, and the other side is fixedly connected to the front hood via bolts.

[0010] In one embodiment, a connecting plate with a pin hole is provided on one side of the front hood opening, and a pin hole is provided on one side of the ventilation grille. The pin shaft is inserted into the pin hole on the ventilation grille and the pin hole on the connecting plate to rotate the ventilation grille to connect to one side of the front hood.

[0011] Beneficial Effects: The protective netting installed outside the ventilation grille significantly reduces the size of coal gangue that can enter the ventilation grille. This effectively improves the reliability of the bulldozer during coal pushing operations without affecting the heat dissipation of the entire machine. The gap between the protective assembly and the bottom of the front hood facilitates the cleaning of fine coal dust accumulated in the front hood.

[0012] Since a protective net is set on the outside of the ventilation grille, the dust on the protective net and between the protective net and the ventilation grille can easily affect the ventilation effect. In this application, the bottom of the protective net and the bottom of the ventilation grille are separated from each other to form a dust discharge port. When a lot of dust accumulates on the protective net or in the gap between the protective net and the ventilation grille, the dust can be discharged through the dust discharge port by patting the protective net or the ventilation grille. The operation is simple and avoids affecting the ventilation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present application will be further described below in conjunction with specific embodiments. Obviously, the embodiments described are only a portion of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative changes are within the scope of protection of the present application.

[0018] like Figures 1 to 3 As shown, the technical solution adopted by the present invention is: a coal-pushing type heat dissipation structure for a bulldozer, comprising a front hood 1 and a protective assembly 2, wherein the protective assembly 2 is installed at the opening of the front hood 1, and a gap 3 is provided between the protective assembly 2 and the bottom of the opening of the front hood 1, and the protective assembly 2 comprises a ventilation grille 21 and a protective net 22, wherein the protective net 22 is fixedly mounted on the outside of the ventilation grille 21, and the bottom of the protective net 22 and the bottom of the ventilation grille 21 are separated from each other to form an ash discharge port.

[0019] By directly fixing a protective net 22 on the outside of the ventilation grille 21 to form a protective assembly 2, the size of the coal gangue that can enter the ventilation grille 21 is greatly reduced, and without affecting the heat dissipation of the entire machine, the reliability of the bulldozer in the coal pushing operation is effectively improved. At the same time, the installation of the protective net 22 also brings some problems, such as dust accumulation in the protective net 22 and the gap between the protective net 22 and the ventilation grille 21. Due to the harsh working conditions of the coal pushing operation, the amount of dust accumulated in the short term may affect the ventilation effect. In order to further solve this problem, the present application designs the structure of the protective assembly 2 so that the bottom of the protective net 22 and the bottom of the ventilation grille 21 are separated from each other to form an ash discharge port. When the amount of dust accumulated in the protective net 22 or the gap between the protective net 22 and the ventilation grille 21 is large, the protective net 22 or the ventilation grille 21 is patted or flushed, and the dust can be discharged from the ash discharge port. Not only is the structure simple, but it is also easy to operate. In addition, the gap 3 between the protective component 2 and the bottom of the opening of the front hood 1 can be used to easily clean out the dust accumulated in the front hood 1.

[0020] As an example, Figure 2 As shown, the protective assembly 2 also includes a gasket 23, and the gasket 23 is arranged at the upper edge, left edge and right edge between the ventilation grille 21 and the protective net 22. That is, the gasket 23 creates a certain distance between the ventilation grille 21 and the protective net 22, and no gasket 23 is provided at the bottom edge between the ventilation grille 21 and the protective net 22, but a dust discharge port is naturally formed. This structure is simple and easy to install. Specifically, the protective net 22 includes a frame 221 and a mesh plate 222, and the frame 221 is enclosed and fixed on the edge of the mesh plate 222. The ventilation grille 21 includes a main structure and ventilation holes arranged on the main structure, and the mesh size on the mesh plate 222 is smaller than the size of the ventilation holes. The ventilation grille 21 and the edge of the protective net 22 are fixedly connected by bolts. During installation, gaskets 23 are set between the upper, left and right sides of the frame 221 of the protective net 22 and the ventilation grille 21, and no gasket 23 is set between the bottom of the frame 221 and the ventilation grille 21, so that the dust discharge port can be formed.

[0021] As another example, Figure 3 As shown, the bottom of the protective net 22 has a protrusion 223 that protrudes away from the ventilation grille 21. The protrusion 223 and the bottom of the ventilation grille 21 form the ash discharge port. In other words, the edges of the protective net 22 and the ventilation grille 21 can directly contact each other, and the protrusion 223 is only provided on the bottom of the protective net 22, thereby separating it from the ventilation grille 21 to form the ash discharge port.

[0022] Specifically, the protective net 22 comprises a frame 221 and a mesh plate 222. The frame 221 surrounds and secures the edges of the mesh plate 222. The lower frame 221 of the protective net 22 is configured to have a protrusion 223 protruding toward a side away from the ventilation grille 21. The ventilation grille 21 comprises a main structure and ventilation holes provided therein. The mesh size of the mesh plate 222 is smaller than that of the ventilation holes. The ventilation grille 21 is fixedly connected to the edges of the protective net 22 by bolts. The ash discharge port is formed between the protrusion 223 and the ventilation grille 21.

[0023] This application provides the above-mentioned form of the ash discharge port, but the protection scope of this application is not limited thereto.

[0024] In another embodiment, Figure 1 and 2 As shown, one side of the protective assembly 2 is rotatably connected to the front hood 1, and the other side is fixedly connected to the front hood 1 via bolts. Furthermore, under normal operating conditions, i.e., when there is less dust, the bolts can be removed and the protective assembly 2 can be opened using the rotating connection structure, thereby opening the front hood 1 to improve heat dissipation.

[0025] Specifically, a connecting plate 11 with a pin hole is provided on one side of the opening of the front hood 1, and a pin hole is provided on one side of the ventilation grille 21. A pin shaft is inserted into the pin hole on the ventilation grille 21 and the pin hole on the connecting plate 11, and the ventilation grille 21 is rotatably connected to the side of the front hood 1. The structure is simple and the operation is convenient.

[0026] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of this application.
