Small tip lorry

Abstract

The invention relates to a small tip lorry which comprises a frame, a storage battery, a traveling steering mechanism, a hopper, a tipping driving mechanism and a seat, wherein one end, far away from the seat, of the hopper is rotatably connected with the frame. The tip lorry is characterized in that the tipping driving mechanism is composed of a first motor, a speed reducer and a gear transmission structure; the gear transmission structure is composed of a support shaft, a first gear, a second gear, a third gear, a fourth gear, a first arc-shaped rack and a second arc-shaped rack, the first gear and the second gear are meshed, the first gear and the fourth gear are fixedly arranged on the support shaft, and the first arc-shaped rack and the second arc-shaped rack are respectively meshed with the third gear and the fourth gear; the bottom surface of the hopper is provided with a connecting shaft; the upper ends of the first arc-shaped rack and the second arc-shaped rack are fixedly arranged on the connecting shaft; and the tip lorry further comprises compacting structures arranged inside the two arc-shaped racks. According to the small tip lorry, the gear transmission structure is driven to move by virtue of the positive rotation and the reverse rotation of the first motor, so that the tipping and resetting of the hopper can be realized conveniently. Compared with the existing tip lorry, the small tip lorry has the advantages that the tipping angle during unloading can be flexibly adjusted according to the material properties, so that thorough unloading is ensured, and the working efficiency of the tip lorry is improved.

Description

technical field [0001] The invention relates to a vehicle for short-distance transportation of materials, in particular to a small dump truck suitable for engineering or agriculture. Background technique [0002] The dump truck is a special short-distance transport material vehicle with a tipping hopper. A "bucket"-shaped container is installed on the body, which can be turned over for easy unloading. At present, common dump trucks are composed of a hopper and a walking chassis. The hopper is installed at the front of the tire walking chassis, and it can be dumped and unloaded with the help of the gravity of the material in the hopper or the thrust of the hydraulic cylinder. Since the tipping and unloading is mainly driven by the hydraulic cylinder, the tipping angle of the hopper is limited, and the tipping angle cannot be flexibly adjusted within a certain angle range according to the actual loading situation, so that it cannot be guaranteed that the material is complete...

Problems solved by technology

Since the tipping and unloading is mainly driven by the hydraulic cylinder, the tipping angle of the hopper is limited, and the tipping angle cannot be flexibly adjusted within a certain angle range according to the actual loading situation, so that it cannot be guaranteed that the material is completely dumped, which in turn affects the work efficiency
