Technical Field

The invention belongs to a light electric material-transporting hand-push dumper in a transport tool.

Background

A dump truck is known to automatically dump a heavy object on the ground by turning over a truck bed from the front to the rear. The device can be mechanically and manually operated, and is characterized in that a carriage chassis of the dump truck is combined on the carriage chassis by a rotating shaft, right-angle flat iron hooks are fixed at two ends of an upper frame of a rear door of the carriage, so that horizontal edges of the hooks are combined with the rear upper ends of the left and right sides of the carriage by pins for convenient disassembly, a right-angle crank connecting rod hook is arranged on the carriage chassis below the rear door and is connected with a chain hole seat at the lower edge of the carriage chassis by an adjustable zipper, when the carriage is flatly placed, the right-angle crank connecting rod hook is tensioned by a chain on the right-angle crank connecting rod hook, and at the moment, the lower edge of the rear door is fastened to; when the carriage begins to incline, the distance between the lower edge of the rear door of the carriage and the chain hole seat is gradually shortened, the chain can loosen, the right-angle crank hook can be automatically opened under the action of gravity, and at the moment, the heavy object in the carriage pushes the rear door open to realize self-unloading. In the society, a plurality of self-discharging trucks mostly realize self-discharging by hydraulic pressure, and the self-discharging trucks have large tonnage and large volume and are not suitable for the transportation of stones, sands, cement, bricks and construction wastes in indoor and outdoor decoration projects with narrow road surfaces and small doorways. The existing electric three-wheel handcart suitable for loading materials in interior decoration of buildings is carried out on the ground by people on foot, only saves a little manpower, has slow speed and low work efficiency, and is not suitable for engineering construction needing remote material transportation; the electric motor is set on the axle of two front wheels, the rear wheel of the chassis is a universal wheel, the handlebar is fixed on the chassis and does not rotate, when the car needs to turn, the car hopper and the chassis rotate together, the person can only control the direction on the ground, the driving is inconvenient and the adaptability is poor.

Disclosure of Invention

The invention provides a handle type three-wheel or steering wheel type four-wheel light hand-push self-discharging electric vehicle which can be used for people to sit on a driving seat from the rear part and walk on the ground to drive from the rear part.

The technical scheme for solving the technical problem is as follows: two wheels driven by a rear axle motor are used as main vehicle wheels and are arranged at the front part of a chassis, a single wheel or a steering wheel type two wheel is arranged at the rear part of the chassis and is used as a wheel for mastering the direction, and the front part of the hand-push self-unloading carriage is combined on the front end of the chassis through a hinge.

Detailed Description

The following description will be made in terms of an embodiment of a four-wheeled electric vehicle in which a semicircular steering wheel is used to determine the running direction.

The bicycle is characterized in that a bicycle disc is a rectangular horizontal frame, the front part of the bicycle disc is combined on two wheels driven by a rear axle motor through a support (comprising a shock absorber) so that the plane of the bicycle disc is higher than that of the two front wheels, a chain hole seat is arranged below the support, the rear part of the bicycle disc is combined on the two rear wheels through the shock absorber through the support, and a battery is arranged below the electric part of the bicycle disc. The main shaft of the semicircular steering wheel is combined with a connecting rod below the bracket and two shock absorber rotating shafts of the rear wheel into a linkage body through a shaft sleeve fixed on the rear end of the steering wheel; the driver seat is connected with the platform surface of the support at the rear end of the chassis through a hinge, can horizontally extend a certain distance backwards and can also be vertically erected on the plane of the support; the foot pedals are respectively arranged on the left side and the right side of the bracket below the shield part of the chassis, and foot brakes are arranged on the foot pedals; when the driving direction is controlled by adopting the semicircular steering wheel, the accelerating rod is arranged on the pedal plate, and the rear side of the bracket platform is also provided with the accelerating handle to realize the driving by conveniently walking on the ground. The front part of the chassis of the hand-push self-unloading carriage is combined on the front end of the carriage chassis by a hinge, a right-angle crank connecting rod hook of the chassis is connected with a chain hole seat at the lower side of a carriage chassis support by a chain, a hand-push self-unloading handle and a spring handle hook for preventing self-unloading are arranged below the rear side of the hand-push self-unloading carriage, and the hook is combined with the carriage chassis into a whole. Obviously, when a person walks on the ground, the person can control the direction by operating the semicircular steering wheel with one hand and can electrically run at a low speed by holding the hand accelerating handle arranged at the rear side of the support platform at the rear part of the chassis with the other hand, and the driver seat can be erected upwards to turn conveniently indoors; because the steering wheel is semicircular, when the flat surface turns to the front, the spring handle which is arranged at the rear side of the carriage and is used for preventing self-unloading can be operated, and the carriage is pushed to carry out self-unloading of heavy objects. Has the advantages that: unique structure, novel style, practicality, convenience, strong adaptability, energy conservation and high efficiency.
