Description

Technical Field

[0001] The utility model relates to the technical field of micro excavators, and more specifically to a new air deflector for a micro excavator. Background Art

[0002] As the power source of an excavator, the engine generates a large amount of heat during operation. This heat needs to be dissipated in a timely manner to ensure that the engine temperature does not become too high, so as to guarantee the normal operation and service life of the engine. Engine heat dissipation usually adopts the engine fan method, which sucks dry cold air outside the excavator into the engine, carries out heat exchange, takes away the heat of the engine, and discharges it from the other side of the engine. However, this method has a drawback that the high-temperature air carrying heat will accumulate inside the excavator housing after being discharged from the engine, and the hot air cannot be discharged in time, resulting in heat accumulation inside the housing. Summary of the Invention

[0003] To solve the above problems and overcome the deficiencies of the prior art, the utility model provides a new air deflector for a micro excavator.

[0004] To achieve the above object, a new air deflector for a micro excavator provided by the utility model includes an engine and a housing. An air outlet mechanism is provided on the engine, and a heat dissipation window is provided on the housing. It includes an air deflector. An air duct through which air can flow is provided inside the air deflector, and the air deflector is installed at the air outlet of the air outlet mechanism;

[0005] The air deflector includes an air inlet and an air outlet communicated with the air duct. The air inlet and the air outlet are respectively located at the head end and the tail end of the air deflector. The air inlet is located at the air outlet of the air outlet mechanism, and the air outlet is located at the heat dissipation window of the housing.

[0006] Further, a baffle is provided at the air inlet, and the vertical section of the baffle is an L-shaped structure.

[0007] Further, a notch adapted to the shape of the air outlet mechanism is provided at the lower part of the baffle.

[0008] Further, a groove is provided at the lower part of the air deflector, and the groove bends inward.

[0009] Further, a number of mounting holes through which bolts can pass are provided on the air deflector, and the air deflector is installed on the housing through bolts.

[0010] Further, a rubber sealing gasket for closing and shock absorption is provided at the mounting holes.

[0011] Further, the air deflector is made of a metal material.

[0012] Further, arc surfaces are provided at the corners of the inner surface of the air deflector.

[0013] The beneficial effects of the utility model are:

[0014] Due to the complex structure inside the casing, the main function of the casing is to provide protection, so its structure is often in the shape of a rectangular shell. After the hot air is discharged into the casing, it cannot flow towards the heat dissipation window on its own, resulting in the accumulation of hot air. In order to eliminate the accumulation of hot air inside the casing, eliminate the phenomenon of heat accumulation, and improve the heat dissipation effect, the present application is provided with a wind guide cover to guide the hot air discharged from the engine to directly flow towards the heat dissipation window without accumulating inside the casing. A baffle is provided at the air inlet. The vertical section of the baffle is in an L-shaped structure, and a notch adapted to the shape of the air outlet mechanism is provided at the lower part of the baffle, ensuring that the air outlet mechanism of the engine is completely covered, so that all the hot air enters the wind guide cover and no hot air escapes.

[0021] To make the purpose, technical solution and advantages of the implementation of the present utility model clearer, the present utility model will be described in more detail below in conjunction with the attached drawings Figure 1 ~Attached Figure 4 , of the present utility model.

[0022] The novel air guide cover 3 of the mini excavator provided by the utility model comprises an engine 1 and a machine housing. An air outlet mechanism 2 is arranged on the engine 1, and a heat dissipation window is arranged on the machine housing. The air guide cover 3 is included. An air duct for air to flow through is arranged inside the air guide cover 3. The air guide cover 3 is installed at the air outlet of the air outlet mechanism 2. The air guide cover 3 comprises an air inlet 31 and an air outlet 34 communicated with the air duct. The air inlet 31 and the air outlet 34 are respectively located at the head end and the tail end of the air guide cover 3. The air inlet 31 is located at the air outlet of the air outlet mechanism 2, and the air outlet 34 is located at the heat dissipation window of the machine housing. A shutter 32 is arranged at the air inlet 31. The vertical section of the shutter 32 is an L-shaped structure. A notch 33 adapted to the shape of the air outlet mechanism 2 is arranged at the lower part of the shutter 32. A groove 36 is arranged at the lower part of the air guide cover 3, and the groove 36 bends inward. A plurality of mounting holes 35 for bolts to pass through are arranged on the air guide cover 3. The air guide cover 3 is installed on the machine housing through bolts. A rubber sealing gasket for closing and shock absorption is arranged at the mounting holes 35. The air guide cover 3 is made of a metal material. Arc surfaces are arranged at the corners of the inner surface of the air guide cover 3.

[0023] The first embodiment is as follows:

[0024] The novel air guide cover 3 of the mini excavator comprises an engine 1 and a machine housing. An air outlet mechanism 2 is arranged on the engine 1, and a heat dissipation window is arranged on the machine housing. The fan of the engine 1 sucks dry cold air into the engine 1, and after heat exchange, it is discharged from the air outlet mechanism 2. The hot air accumulates in the machine housing, and part of it is discharged to the outside of the machine housing from the heat dissipation window.

[0025] Since the structure inside the machine housing is complex and the machine housing mainly plays a protective role, its structure is often a rectangular shell shape. After the hot air is discharged into the machine housing, it cannot flow to the heat dissipation window independently, resulting in the accumulation of hot air. In order to eliminate the accumulation of hot air inside the machine housing, eliminate the heat accumulation phenomenon, and improve the heat dissipation effect, the air guide cover 3 is provided in this application to guide the hot air to directly flow to the heat dissipation window after being discharged from the engine 1, rather than accumulating in the machine housing.

[0026] The structure of the air guide cover 3 is streamlined, which is convenient for the flow of hot air. A plurality of mounting holes 35 for bolts to pass through are arranged on the air guide cover 3. The air guide cover 3 is installed on the machine housing through bolts and does not contact the engine 1, so there will be no interference. A rubber sealing gasket for closing and shock absorption is arranged at the mounting holes 35. On the one hand, it ensures that the hot air will not overflow from the mounting holes 35, and on the other hand, it can also prevent noise or bolt loosening caused by vibration.

[0027] Inside the air guide cover 3, there is an air duct for air to flow through. The air guide cover 3 includes an air inlet 31 and an air outlet 34 that communicate with the air duct. The air inlet 31 and the air outlet 34 are respectively located at the head end and the tail end of the air guide cover 3. The air inlet 31 is located at the air outlet mechanism 2, and the air outlet 34 is located at the heat dissipation window of the casing. After the hot air is discharged from the engine 1, it directly enters the air guide cover 3. When the hot air is discharged, there is a tendency to flow, so it will directly flow along the air guide cover 3 to the air outlet 34 and then be discharged from the heat dissipation window.

[0028] A baffle 32 is provided at the air inlet 31. The vertical section of the baffle 32 is an L-shaped structure. A notch 33 adapted to the shape of the air outlet mechanism 2 is provided at the lower part of the baffle 32, which ensures that the air outlet mechanism 2 of the engine 1 is completely covered, so that all the hot air enters the air guide cover 3 and no hot air escapes.

[0029] A groove 36 is provided at the lower part of the air guide cover 3. The groove 36 bends inward, leaving space for installing other structures on the casing. At the same time, it also improves the streamline of the air duct inside the air guide cover 3 and the smoothness of the air flow.

[0030] The air guide cover 3 is made of metal material to ensure the strength of the structure.

[0031] Arc surfaces are provided at the corners of the inner surface of the air guide cover 3 to improve the smoothness of the hot air flow and prevent backflow or blockage.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
