Problems solved by technology

Since the overall scraper sliding device is set on the bottom plate of the carriage, it occupies the effective volume of the carriage; the scraper adopts a single-row vertical arrangement, which is not suitable for transporting goods with large specific gravity and uneven particle size, and it is easy to deform the scraper; drive The driving wheel of the scraper sliding device is set at the front of the carriage, which increases the load of the chain involved in the work; due to the use of the bushing chain, when transporting wet goods, the bushing chain is easily corroded, resulting in a long service life of the chain reduce

Embodiment 1

[0026] Connect the tailgate 1 with the pin shaft 11 at the upper ends of the side fenders 2 and 39 on both sides of the carriage; on both sides of the carriage floor 44 and the middle ridge 12, the left and right limit grooves at the bottom of the side fenders 2 and 39 on both sides of the carriage The two upper rails formed by 42 and 40 are respectively provided with scraper sliding devices (see figure 1 , figure 2 ), each set of scraper sliding device is composed of two groups of chains 4, the front scraper 5, the middle scraper 6 and the rear scraper 7 are one group, the front scraper 5 and the middle scraper 6 are another group, and the two groups of scrapers Plates are fixedly connected on every group of chains 4 at intervals, and every group of chains 4 is meshed with tail wheels 13,48,51,52 ( image 3 , Figure 4 ). The space surrounded by the skeleton longitudinal beams 37, 15 on both sides of the carriage floor, the skeleton longitudinal beam 41 in the middle of t...

Embodiment 2

[0032] Embodiment 2 just changes the self-locking device etc. of the tailgate 1 of embodiment 1, and the tailgate 1 top is installed on the two side plates 2,39 by pin shaft 11. On the left side of the tailgate 1, one end of the left pole 58 is connected with the tailgate 1 through a pin, and the other end is connected with the left rack 61 through a pin; the left rack 61 meshes with the left ratchet 62, and the left ratchet Left stay wire 57 is tied on 62; The device structure on the right side of tailgate 1 is identical with the device structure on the left side, and left and right stay wire 57,56 are tied on the handle 59 respectively (see Figure 11 , Figure 12 ). When the goods will be unloaded, at first the locking card 36 will be opened, and then the self-unloading system will be opened, and part of the goods will rush to the tailgate 1 due to the effect of dead weight, and the tailgate 1 will be opened with the bearing pin 11 as an axis. At this time, the left pole ...

Abstract

The invention relates to the field of vehicle unloading materials, in particular to a scraper type self-unloading device. Composed of a hydraulic transmission device and a scraper sliding device, the invention has a simple structure and has a wider application range than the cargo compartments that are turned over backwards or sideways. It does not block the road, does not block the vehicle, and the bulk material falls evenly, the unloading body is stable, safe and reliable, and at the same time avoids the sideways or backward tilt of the impact frame caused by the sudden slide of the bulk material. The invention not only improves the service life of the side door of the cargo compartment, but also has the advantages of reliable performance, simple operation, time-saving, labor-saving and labor-saving advantages, and fundamentally solves the problem of manual unloading of full-loaded and extended semi-trailer trucks.

Description

technical field [0001] The invention relates to an automatic unloading device for automobiles, in particular to a scraper type automatic bulk material unloading device for heavy trucks. Background technique [0002] In recent years, my country's automobile industry has developed rapidly, especially in the field of heavy trucks. Its development trend is large-scale and heavy-duty, and the load-carrying capacity has also been rapidly increased. Such original self-unloading devices can no longer keep up with the development of heavy-duty trucks, especially in the self-unloading of four-axis, five-axis and six-axis full-trailer series and extended semi-trailer series of heavy-duty truck series. When unloading by tilting, the stability of the vehicle body is poor, and when the bulk material is hard and pointed, it will cause vicious damage to the tire; sometimes after the bulk material is unloaded, the tire will be filled with cargo, so that the vehicle body is difficult to get o...
