Abstract

A scraper-type self-dumping device of a heavy lengthening trailer comprises a backboard (1), sideboards (2, 39), an auxiliary cross beam (3) and a front board (10). The utility model is characterized in that top ends of the two sideboards (2, 39) of a carriage are connected to the backboard (1) via pins (11); a scraper sliding device is arranged at two upper rails formed by a soleplate (44) of the carriage and two sides of a middle ridge (12), and by left and right position-limiting grooves (42, 40) at the bottom of the two sideboards (2, 39) respectively. Each scraper sliding device consists of two groups of chains (4). A front scraper (5), a middle scraper (6) and a rear scraper (7) are a group, while the front scraper (5) and the middle scraper (6) are another group. The two groups are fixed at the two groups of chains (4) alternately. Each group of chains mesh with rear wheels (13). The utility model consists of a hydraulic transmission device and scraper sliding devices, and is simple in the structure. Compared with a back-dumping or side-dumping a cargo carriage, the utility model is widely applicable. The utility model is capable of self-dumping, when the trailer is stopped or running. Moreover, cargos are all unloaded behind the trailer without blocking the road or stopping the trailer. Bulk materials fall down evenly. The trailer body is stable, safe and reliable at unloading. Meanwhile, the case that a vehicle frame falls sideward or backwards due to an impact caused when bulk materials slide down immediately is avoided. The utility model not only prolong the usable life of side doors of the cargo carriage, but also is provided with the advantage of reliability performance, simple operation, and saving time, labor and strength. The utility model fundamentally settles the problem of manual dumping for a heavy full-trailer or a lengthening cargo semi-trailer.

Description

Scraper type autounlouding device of heavy lengthened trailer

Technical field

The present invention relates to the automatic discharging gear of a kind of automobile, particularly relate to a kind of heavy duty truck scraper plate and unload bulk material device automatically.

Technical background

Domestic Automotive Industry was in develop rapidly in recent years, and what show in the heavy duty truck field is particularly outstanding, and its development tendency is maximization, heavy-duty, and load-carrying ability has also obtained soaring rapidly.Original like this self-unloading device has not caught up with the development of heavy duty truck, and outstanding behaviours is in the full self-unloading of hanging series and lengthening semi-mounted series heavy duty truck series of four, five and six.Use inclination unloading, the vehicle body poor stability can cause malignant lesion to tire when the hard band of bulk cargo is sharp; Sometimes tire can be filled by goods down after unsnatching bulk cargo, to such an extent as to car body is difficult to get away.Sometimes also do not slide to the certain angle bulk cargo when the car body inclination, then can cause the serious consequence of car load rollover.Certainly the technology of turning over makes the problems referred to above obtain solution after using, but brought even more serious problem simultaneously again, when after the technology of turning over when being used for that four, five and six are complete to hang series and lengthening semi-mounted series heavy duty truck at the bottom of the car body at the bottom of skeleton and the car body between skeleton and the crossbeam twisting be in and will be subjected to great instantaneous moment when unloading bulk cargo, therefore the length, the load-carrying capacity that overturn of back all has been subjected to strict restriction, also have simultaneously when unloading after overturning envelope platform be raised to certain angle after the bulk cargo serious consequence that then can cause headstock to swing back when also failing landing.

Summary of the invention

In order to overcome the prior art above shortcomings, the invention provides a kind of heavy lengthened trailer scraper plate self-unloading device, this invention can guarantee the stability and the fastness of vehicle body, do not change the force structure of vehicle body main body, it is advantageous that this self-unloading device does not limit bodywork length, the restricting vehicle load-carrying capacity can not guarantee the leakproofness in compartment simultaneously yet and unload back noresidue bulk cargo.

The technical solution adopted for the present invention to solve the technical problems is: the upper end at both sides,

Downside at front apron 10 is provided with rubber block 9 to strengthen the car body leak tightness, and tail wheel 13 lower ends are provided with rubber block 14 to strengthen the car body leak tightness.

Great wheel

8,29 is a flower wheel, its position can vertically move, to realize tighten (the seeing Fig. 5, Fig. 6) of chain, left and right

great wheel

8,29 is installed on the left and right

great wheel axle

31,28, the two ends of left and right

great wheel axle

31,28 are separately fixed on the left and right travel(l)ing

rest

32,30, adjust

screw rod

21,25,26,27 and be threaded, on each travel(l)ing

rest

32,30 lock nut 24 is set with the two ends of travel(l)ing rest 32,30.When

screw rod

21,25,26,27 was adjusted in turn, great wheel travel(l)ing

rest

32,30 degree of tightness that realizes chain that can be along the longitudinal movement was regulated, and tie down screw 24 when degree of tightness is fit to is with fixing great wheel travel(l)ing rest 32,30 (seeing Fig. 5, Fig. 6).

The upper end of back shield 1 left and right sides is welded two swing handles 34 respectively, is fixed in the compartment rear side with bearing pin 11 for axle, and each swing handle 34 end is by the piston rod 35 of bearing pin 33 connection hydraulic actuating cylinders, and the lower end of back shield 1 is provided with locking card 36.When unloading, the piston rod 35 of hydraulic actuating cylinder moves downward, and back shield 1 is opened unloaded goods.After goods was unsnatched, piston rod 35 upward movements of hydraulic actuating cylinder made back shield 1 closure, and hydraulic actuating cylinder has end points auto-lock function (see figure 7).Right baffle-plate 2 and right baffle plate 39 upper ends are linked together (see figure 8) with steel rope 38.

Embodiment 2:
