Embodiment Construction

[0021] The truck self-unloading device of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 As shown, the truck self-unloading device of the present invention includes a car body 1, a cargo compartment 2 and a lifting mechanism 3, and the rear portion of the cargo compartment 2 is provided with a lifting lug 4, which is hinged with the vehicle body 1 through the lifting lug 4, so that The cargo compartment 2 can be overturned relative to the vehicle body 1 with the center of the lifting lug 4 as the axis. The rear portion of the loading compartment 2 is also provided with a discharge port 5, and the goods are discharged from the discharge port 5 during unloading. The lifting mechanism 3 includes a driving mechanism 11, a rocker 6 and a connecting rod 7. The two ends of the rocker 6 are respectively provided with a first hinge point 8 and a second hinge point 9, and the rocker...

Abstract

The invention relates to the field of dump trucks and provides a dumping device for a truck. The dumping device comprises a cargo loading carriage and a lifting mechanism, wherein a discharging opening is formed in the rear part of the cargo loading carriage; the cargo loading carriage is arranged on a truck body and is hinged to the truck body through lifting lugs at the rear part of the cargo loading carriage; the lifting mechanism comprises a driving mechanism, a rocking bar and connecting rods; the rocking bar is hinged to the truck body through a first hinge point arranged at one end of the rocking bar and is hinged to the connecting rod through a second hinge point arranged at the other end of the rocking bar; the connecting rods are hinged to the cargo loading carriage through third hinge points arranged on the connecting rods; the driving mechanism acts on the first hinge point of the rocking bar, so that the rocking bar rotates relative to the first truck body at the first hinge point, and the turning of the cargo loading carriage is realized; a material retaining plate is connected to the rear part of the connecting rod; when the cargo loading carriage turns, the discharging opening is automatically opened by the material retaining plate, and the dumping process of cargoes is realized. The dumping device disclosed by the invention is simple in structure and easy for maintenance; the turning of the cargo loading carriage is realized by a four-link mechanism. Compared with linear motion of a traditional hydraulic rod, the motion mode disclosed by the invention has the advantage that insufficient strength caused by overlong extension of a piston rod is overcome.

Description

technical field [0001] The invention relates to the field of dump trucks, in particular to a dump device for loaded trucks. Background technique [0002] Dump trucks refer to vehicles that unload goods by themselves through hydraulic or mechanical lifting, also known as dump trucks. Generally speaking, dump trucks are equipped with a set of hydraulic lifting mechanisms on the current dump truck chassis. The car engine drives the hydraulic lifting mechanism, tilts the carriage at a certain angle to unload, and relies on the weight of the carriage to reset it. The emergence of the dump truck is a handling device developed by using high technology when the work of handling is no longer manpower can solve with the development of the times. [0003] The dump truck is composed of a car chassis, a lifting mechanism, a cargo compartment and a power take-off device. Because the loading compartment can automatically tip over at a certain angle, the goods in the loading compartment c...
