Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, and in particular to a grain surface leveling device. Background Technology

[0002] Grain storage warehouses have a large grain surface area; for example, a warehouse that is 50m long and 21m wide has a grain surface area exceeding 1000m². 2 After grain is stored in the warehouse, the surface of the grain pile is usually uneven. Workers need to use grain suction machines and handcarts to initially level it, and then use rakes and scrapers to level the grain surface. Given the large area of ​​grain surface leveling, the poor working environment inside the warehouse, and the poor leveling skills of young employees, manual leveling with traditional leveling tools is inefficient, time-consuming, and produces poor leveling quality. This seriously restricts the improvement of the level of refined warehouse management. Moreover, working in the grain warehouse for a long time can also affect the physical and mental health of the workers. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a grain surface leveling device that is easy to use, has high efficiency in leveling grain surfaces, and has a good leveling effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A grain surface leveling device includes two sets of parallel vehicle bodies, a grain combing mechanism located between the ends of the vehicle bodies, and a grain pressing mechanism located between the middle parts of the vehicle bodies. Each vehicle body includes a frame and wheels located at the bottom of the frame, with handle assemblies mounted on the frame. The grain combing mechanism includes a crossbeam, a plurality of comb rods evenly fixed to the crossbeam, and height adjustment assemblies located at both ends of the crossbeam and connected to the frame, with the lower ends of the comb rods extending beyond the lower end face of the crossbeam. The grain pressing mechanism includes a grain pressing roller and connecting arms located at both ends of the grain pressing roller, the connecting arms being rotatably connected to the frame, and the grain pressing roller adaptively maintaining contact with the grain surface under gravity.

[0006] By adopting the above technical solution: two walkways are laid on the grain surface for the vehicle to travel on. The height of the crossbeam is adjusted by the height adjustment mechanism so that the comb rod is inserted into the grain surface. The crossbeam is located above the grain surface, and the vehicle is pushed to move along the walkways. The crossbeam first performs peak removal on the grain surface. Then the comb rod initially flattens the grain surface. Finally, the pressing roller flattens the grain surface when it passes over the initially flattened grain surface. Through the coordinated action of the crossbeam, comb rod, and pressing roller, the grain surface is quickly leveled. It is very convenient to use, has high efficiency in leveling the grain surface, and has a good leveling effect.

[0007] Preferably, the height adjustment assembly includes a connecting frame, a connecting sleeve, and a lead screw. One end of the connecting frame is detachably connected to the vehicle frame. The connecting sleeve is vertically rotatably connected to the connecting frame. The lead screw extends from the lower end of the connecting sleeve into the connecting sleeve to form a threaded connection. The lower end of the lead screw is fixedly connected to the crossbeam. The upper end of the connecting sleeve is provided with an adjusting handle for driving the connecting sleeve to rotate. By adjusting the handle to drive the connecting sleeve to rotate, the height of the crossbeam can be adjusted to meet the leveling requirements of different grain surfaces.

[0008] Preferably, both ends of the frame are fixed with locking seats, and one end of the connecting frame is inserted into the locking seats and fastened with bolts and nuts. This makes the installation and disassembly of the grain combing mechanism and the frame more convenient.

[0009] Preferably, a bearing seat is fixed on the frame, and a bearing is installed inside the bearing seat. The lower end of the connecting arm is rotatably connected to the grain pressing roller, and the upper end of the connecting arm is provided with a connecting shaft rotatably connected to the bearing seat. The connecting arm, in conjunction with the connecting shaft, bearing, and bearing seat, are rotatably connected, allowing the grain pressing roller to adaptively press against the grain surface under gravity. This reduces travel resistance and better adapts to the grain surface.

[0010] Preferably, the handlebar assembly includes a handlebar seat and a handlebar lever. The handlebar seat is fixedly connected to the vehicle frame, and the handlebar lever slides through the handlebar seat to form a sliding connection. A positioning bolt for positioning the handlebar lever is provided on the side of the handlebar seat. Loosening the positioning bolt allows for free adjustment of the handlebar lever's length to meet the needs of different users.

[0011] Preferably, each frame has two wheels at its base, which are swivel wheels. Swivel wheels facilitate better steering of the vehicle.

[0012] Preferably, the crossbeam is made of several sections of square tubes connected together, and the grain pressing roller is made of several sections of round tubes connected coaxially.

[0013] Therefore, this utility model has the advantages of being easy to use, having high efficiency in leveling grain surfaces, and providing good leveling results. Attached Figure Description
