Description

Technical Field

[0001] The utility model belongs to the technical field of lifting pump brackets, and specifically relates to a combined lifting pump bracket for a harvester transport vehicle. Background Art

[0002] A harvester is an agricultural machine used to efficiently complete the harvesting work of large areas of farmland crops, which can significantly improve agricultural production efficiency and reduce the labor burden.

[0003] A harvester transport vehicle is a vehicle specially designed for transporting harvesters, usually used for the cross-regional operation of agricultural machinery. The harvester transport vehicle has special functions and configurations in design to meet the requirements during long-distance transportation. The harvester transport vehicle needs to have sufficient load capacity and size to ensure that it can safely load and transport large harvesters.

[0004] The lifting pump of a harvester transport vehicle is a hydraulic device used to realize the lifting function of the harvester transport vehicle. The lifting pump usually obtains power from the gearbox through a power take-off and drives the lifting cylinder through a hydraulic system to realize the lifting action. The lifting pump can adopt a gear pump or a variable piston pump. The gear pump is less sensitive to hydraulic oil pollution, while the variable piston pump can automatically reduce the displacement when not lifting, having an energy-saving effect.

[0005] To meet the requirement that the center of gravity of the harvester is as low as possible when it gets on the vehicle, the chassis of the harvester transport vehicle needs to be designed with a low loading platform, that is, the height of the vehicle chassis is reduced. This will cause the stroke of the existing manual crank of the lifting pump to be limited, and harvester users need to install parts such as toolboxes and water tanks on the vehicle frame, resulting in insufficient layout space of the existing vehicle frame. Content of the Utility Model

[0006] To solve the problems that the low loading platform design of the chassis of the harvester transport vehicle will cause the stroke of the existing manual crank of the lifting pump to be limited and the layout space of the vehicle frame to be insufficient, the utility model provides a combined lifting pump bracket for a harvester transport vehicle.

[0007] The utility model is realized through the following technical solutions:

[0012] A further improvement of the present invention is that two drawstring holes are provided on one side of the first bracket close to the longitudinal beam of the vehicle frame.

[0013] A further improvement of the present invention is that the second bracket is formed by welding a rectangular steel pipe, and both ends of the second bracket are respectively fitted with the first bracket and connected through connecting bolts.

[0014] A further improvement of the present invention is that an air intake pipe fixing bracket is connected and installed on the rear side of the upper horizontal section of the second bracket.

[0015] A further improvement of the present invention is that the lifting pump mounting bracket is an L-shaped bending structure, one of which is welded to the upper end of the vertical section of the second bracket, and an electric lifting button mounting bracket supported on the upper horizontal section of the second bracket is bent on the bending surface.

The manual crank of the electric lifting pump 3 is arranged in the gap between it and the fender 5, without interference with its up - and - down swing path, avoiding the problem of limited stroke of the manual crank of the electric lifting pump 3. The overall structure is simple, easy to implement, and has good practicability.

[0034] As Figure 1-8As shown, the air filter mounting bracket includes a first air filter mounting bracket 66 positioned and connected to the rear side of the lower horizontal section of the second bracket 62, a second lower air filter mounting bracket 662 positioned and connected to the rear side of the lower horizontal section of the second bracket 62, and a second upper air filter mounting bracket 661 positioned and connected to the rear side of the vertical section of the second bracket 62; the first air filter mounting bracket 66 includes a vertical plate and a bent plate bent at both ends of the vertical plate, and the bent plate is provided with a connecting mounting hole, and the lower bent plate and the lower part of the vertical plate are welded and fixed to the rear side of the lower horizontal section of the second bracket 62; the second lower air filter mounting bracket 662 is an S-shaped bent plate structure, and is welded and fixed to the front side of the lower horizontal section of the second bracket 62. The middle section of the air filter second upper mounting bracket 661 is a U-shaped bent plate structure, with the middle section erected and welded to the rear side of the second bracket 62. Its lower wing plate has a connecting hole, and the front side of the lower wing plate is bent downward to form a welding plate that is welded to the rear side of the second bracket 62. The air filter mounting bracket also includes two air filter mounting transition brackets 7 for mounting the air filter 2. One air filter mounting transition bracket 7 is connected to the two connecting holes on the first air filter mounting bracket 66, and the other air filter mounting transition bracket 7 is connected to the connecting holes on the second lower air filter mounting bracket 662 and the second upper air filter mounting bracket 661.

[0035] Furthermore, the air filter mounting transition bracket 7 includes a U-shaped support frame 71, through which two connecting bolts for connecting to the air filter 2 are inserted. A folding plate 72 is bent vertically outward from the edge of one side wing of the support frame 71. The upper and lower edges of the folding plate 72 are bent with connecting plates 73 welded to the side wing of the support frame 71. Connecting bolts are inserted into the connecting plate 73 to connect to the air filter mounting bracket (connection mounting holes). The air filter mounting transition bracket 7 has a simple structure, good strength, and a reliable transition connection to the air filter 2.

[0036] Furthermore, a support plate 74 is provided between the upper connecting plate 73 and the folding plate 72 to effectively ensure the strength of the connecting structure.
