Description

Technical Field

[0001] The utility model relates to the technical field of semi-trailers, and more specifically to a semi-trailer with a material pushing component. Background Art

[0002] Dump trailer refers to a type of semi-trailer that can automatically tip over the angle of the carriage to quickly complete the unloading task when unloading. It has high unloading efficiency, which can greatly save unloading time and labor, shorten the transportation cycle, and improve production efficiency. At present, most of the dump trailers on the market are flatbed dump trailers. When unloading, the front end of the carriage is lifted to tilt it backward, and the gravity of the cargo is used to complete the unloading of the cargo in the carriage.

[0003] Sand is a commonly used construction material. Semi-trailers are often used for transportation during construction. In order to prevent the sand from being blown away by the wind and leaking, water is usually poured into the sand to make it stick together. During transportation, the sand will be compacted continuously with the vibration of the vehicle body, causing the sand to become firm and agglomerated. It is difficult to use the sand's own gravity to complete the unloading of the sand in the carriage during unloading. Workers need to shovel the sand out of the carriage with a shovel, which is labor-intensive and troublesome. In view of this, we propose a semi-trailer with a pusher assembly. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a semi-trailer with a pushing component to solve the technical problem that when the existing semi-trailer unloads sand in the compartment, workers need to use shovels to shovel sand out of the compartment, which consumes a lot of manpower and is relatively troublesome.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a semitrailer with a material pushing assembly, comprising a semitrailer, the semitrailer comprising a tractor and a carriage arranged at the traction end of the tractor; and further comprising a dispersed pushing mechanism, the dispersed pushing mechanism being arranged at one side of the carriage;

[0006] The dispersed driving mechanism includes a motor A, a screw rod, a guide rod and a C-shaped support frame. The motor A is fixedly installed on the surface of the opposite end of the carriage and the tractor through a mounting plate. Both ends of the screw rod are rotatably connected to the two ends of the outer wall of one side of the carriage through mounting bearings. The output end of the motor A is transmitted to one end of the screw rod through a toothed plate and a chain, and both ends of the guide rod are fixedly connected to the two ends of the outer wall of the other side of the carriage through a mounting seat. The C-shaped support frame cover is arranged on the top of the carriage, and the two ends of the bottom of the C-shaped support frame are movably connected to the screw rod and the guide rod respectively. The top of the C-shaped support frame is fixedly installed with a motor B by screws, and a plurality of rotating shafts are equidistantly penetrated at the top of the top of the C-shaped support frame. The output end of the motor B is transmitted to one end of the rotating shaft through a bevel gear set, and the two adjacent rotating shafts rotate in opposite directions through gear meshing. The rotating shaft extends into the carriage and is provided with a plurality of stirring blocks.

[0007] Preferably, the stirring blocks on two adjacent rotating shafts are arranged in a staggered state.

The C-shaped support frame 204 The cover is arranged on the top of the carriage 102, and the two ends of the bottom of the C-shaped support frame 204 are movably connected with the screw rod 202 and the guide rod 203 respectively. The top of the C-shaped support frame 204 is fixed with a motor B205 by screws. A plurality of rotating shafts 206 are evenly spaced through the top of the C-shaped support frame 204. The output end of the motor B205 is transmitted to one end of one of the rotating shafts 206 through a bevel gear set. The two adjacent rotating shafts 206 rotate in opposite directions through gear meshing. The rotating shaft 206 extends into the carriage 102 and is provided with a plurality of stirring blocks 207; A threaded sleeve 2041 is provided at one end of the C-type support frame 204, and one end of the C-type support frame 204 is threadedly connected to the surface of the screw rod 202 through the threaded sleeve 2041; a sliding sleeve 2042 is provided at the other end of the C-type support frame 204, and the other end of the C-type support frame 204 is slidably connected to the surface of the guide rod 203 through the sliding sleeve 2042; when unloading, the box door at one end of the carriage 102 is opened, and the motor B205 is driven by the external control mechanism. The motor B205 is driven by one end of one of the rotating shafts 206 through a bevel gear set, and the rotating shaft 206 is meshed with gears.
