An unloading device for a transport vehicle

Abstract

The invention relates to an unloading device for a transport car and discloses a self-push device for sand unloading with automatic pushing of sand by a floor, wherein the device is formed through coordination of three groups of slide rails. The unloading device is characterized by comprising a bottom fixation frame, slide baseplates and a push-pull component, wherein the slide baseplates are placed on the bottom fixation frame in a movable manner; the push-pull component is placed on the bottom of the slide baseplates; the bottom fixation frame is constituted of two vertical rods and two horizontal rods; the two horizontal rods are placed between the two vertical rods; two ends of each of the horizontal rods are vertically connected to the two vertical rods; the slide baseplates comprisea No.1 slide baseplate, a No.2 slide baseplate and a No.3 slide baseplate; the No.1 slide baseplate is constituted of a No.1 slide rail and a No.2 fixed baseplate; the No.2 slide baseplate is constituted of a No.2 slide rail and a No.2 fixed baseplate; and the No.3 slide baseplate is constituted of a No.3 slide rail and a No.3 fixed baseplate. A carriage does not need to be turned over at an angle; noise is low during sand unloading; loads borne by the sand unloading device are low; and the device is not damaged easily.

Description

technical field [0001] The invention relates to a cargo unloading device for a transport vehicle, which relates to a device for unloading sand when transporting sand by a transport vehicle, and belongs to the field of construction equipment. In particular, it relates to a device for automatically pushing out sand and unloading sand by forming an automatic propulsion floor through the cooperation of three sets of slide rails. Background technique [0002] Sand is widely used as a raw material for construction concrete. At the same time, due to the large demand for sand and its bulk form, transport vehicles are often used for transportation. However, when unloading sand at present, because the sand body is in bulk form, The indeterminate shape is extremely inconvenient when unloading sand in the transport box.

[0002] Sand is widely used as a raw material for construction concrete. At the same time, due to the large demand for sand and its bulk form, transport vehicles are often used for transportation. However, when unloading sand at present, because the sand body is in bulk form, The shape is indeterminate, which is extremely inconvenient when unloading sand in the transport box. Traditionally, sand unloading is carried out by manual shoveling. Manual sand unloading is slow, low in efficiency, high in labor costs, and labor-intensive.

[0003] Notification number CN207826313U discloses a sandstone transport vehicle for construction engineering, comprising a frame body, walking wheels connected to the four corners of the bottom surface of the frame body, a pair of handles connected to the rear side of the frame body, connected to the The vehicle bucket on the top surface of the frame body and the bucket arranged in front of the vehicle bucket, a hydraulic cylinder is arranged between the vehicle bucket and the bucket, and the vehicle bucket is a rectangular box-shaped body with an opening on the top surface. There is a rectangular discharge opening at the bottom of one side, and the top of the front side is provided with an outwardly extending feeding bucket; the bucket is hinged on the bucket through a pole, and the pole is located directly below the feeding bucket The outer end of the support rod is higher than the feed hopper. When unloading the sand, the transport vehicle relies on the gravity of the sand itself to unload the sand. The sand unloading speed is slow and the efficiency is low. Easy to stop, cause blockage

[0004] The notification number CN107618425A discloses a dump truck with a load limiting function, which includes a car body and a compartment installed on the car body. The head of the compartment is provided with a limit baffle, and the middle part of the hydraulic cylinder is hinged and fixed on the compartment near the front of the vehicle. The top of the hydraulic rod is connected to the car body; the tailgate of the compartment is hydraulically locked, and a car body cover with a load-limiting function that cooperates with the limit baffle is set on the upper part of the compartment. The device tilts the cargo box through the hydraulic rod to dump the sand in the box. The hydraulic rod bears a large load, and due to the limited inclination angle of the truck, it is difficult to completely dump the sand in the box, and manual sand shoveling is still required for unloading in the subsequent sequence.
