Description

Technical Field

[0001] The utility model relates to the field of heat dissipation regulation, in particular to an adjustable ventilation side door used in engineering machinery. Background Art

[0002] At present, many products in the construction machinery industry use suction cooling, such as excavators, that is, the fan draws cool air through the side door opening and blows it to the radiator surface to take away the heat. Construction machinery manufacturers open the side door according to the heat dissipation requirements, and the size and shape vary.

[0003] Although the shapes and sizes of the air inlet openings on the side doors of current engineering machinery products are different, the size and area of ​​the air inlet openings on the side doors are determined by the manufacturer after production and assembly, and cannot be directly adjusted during subsequent user use. For example, the application with publication number CN204676631U in the prior art discloses a sealing structure for the power compartment of an excavator, which includes a shell and a detachable sealing plate. The shell is divided into an engine room and a radiator room by a partition with multiple ventilation holes. An air outlet is provided on the top of the engine room, and a side door of the radiator room is movably connected to the shell. An air inlet is provided on the side door, and a detachable sealing plate is fixed on the inner wall of the side door and covers the air inlet. However, the fixed air inlet cannot be adjusted and cannot meet the use requirements under different ambient temperatures. Due to the large difference in ambient temperature between summer and winter or between tropical and cold regions in the same region, the engine water temperature, intercooler intake temperature and whole machine hydraulic oil temperature will also vary greatly during operation of engineering machinery under the same air intake and heat dissipation. Too low or too high water temperature and hydraulic oil temperature are not conducive to the operating efficiency and fuel consumption of the product. At present, there is a lack of a side door structure that can adjust the size of the vent. Summary of the invention

[0004] The purpose of the utility model is to provide an adjustable ventilation side door applied to engineering machinery, so as to solve the problem that the air intake volume of the radiator vent cannot be adjusted in the prior art.

[0005] The utility model is realized by the following technical solutions:

[0006] An adjustable ventilated side door used in engineering machinery comprises a side door assembly, a plurality of radiators are arranged on the inner side of the side door assembly, a side door panel is arranged on the side door assembly, a plurality of vents are arranged on the side door panel, the vents correspond to the radiators, a baffle is slidably provided on the vent, a handle is arranged on the baffle, and a limiting structure is arranged on the baffle to effectively prevent arbitrary sliding.

[0007] Furthermore, the side door panel is provided with a track with two open ends, and the track is slidably connected to a baffle.

[0008] Furthermore, the handle adopts a U-shaped bolt, and the U-shaped bolt is fixed to the baffle through a nut.

[0009] Furthermore, there are three vents, which are vertically equidistantly distributed and correspond to three radiators respectively. Baffles of different lengths can be selected according to different adjustment requirements of the side door vents. The three vents are all provided with baffles, which include baffle I, baffle II and baffle III. Baffle I, baffle II and baffle III correspond to one vent respectively, so that each vent can adjust the opening area independently.

[0010] Furthermore, the limiting structure includes a butterfly bolt, a rubber head is provided on the butterfly bolt, the rubber head passes through the side door plate and is contacted and connected to the baffle plate, and the butterfly bolt is threadedly connected to the side door plate.

[0011] Furthermore, the side door panel is provided with a through hole, a nut is welded at the position of the through hole, and the butterfly bolt passes through the through hole and is threadedly connected to the side door panel through the nut, thereby effectively preventing any sliding.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model reduces or increases the ventilation area of ​​the side door of the engineering machinery by moving the sliding baffle left and right, thereby meeting the use requirements under different ambient temperatures.

[0014] 2. The utility model adopts a one-to-one correspondence between radiators and vents, and three radiators correspond to three vents, so that the area of ​​each vent can be adjusted separately.

[0015] 3. The utility model adopts a rotatable butterfly bolt to press and fix the slidable baffle through a rubber head with a nut embedded therein, thereby effectively preventing any sliding. BRIEF DESCRIPTION OF THE DRAWINGS
