The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.As shown in Figure 1, the self-unloading casing assembly of being made up of three joint casings separates with intermediate hsg 15, casing B, middle casing C, rear box A three parts before being divided into.In order to guarantee that side box plate has enough intensity, on intermediate hsg 15, be equiped with oblique straining beam 17,20 fens and arranged on left and right sides of tipping hydraulic lifting cylinder are installed on the dumping car chassis below each casing, and the upper end connects the last lifting base plate 18 and the following lifting base plate 21 of each casing respectively.Centre joint Antileaking plate 16, one ends that the installing sheet steel is made between Da Jie last lifting base plate 18 and the following lifting base plate 21 are connected with last lifting base plate 18 limit ends by rotating hinge 3 up and down, and the other end is directly taken the plane of putting at following lifting base plate 21.Bottom-open type chamber door 5 is lifted on the casing upper side frame 6 by rotating hinge 3, and mechanical safety 8 is installed on bottom-open type chamber door 5 and the casing underframe 11, as shown in Figure 1.Before casing B, middle casing C, rear box A three joint casings can realize respectively unpacking automatically by the control system operation, lifting dumps.The preceding boxboard 1 of container adopts integral structure, as shown in Figure 2.Rearing-box plate 7 adopts opposite opened back door 14 and adopts mechanical safety 8 lockings, and back door 14 is installed on the rear box A, as shown in Figure 3 by rotating hinge 3.If when needing the casing lifting, earlier mechanical safety 8 is all opened, the handle 55 that is installed in the front and back case switch 54 on the operation control panel 44 is turned round to the right or raising middle flask switch 56 is turned round (as shown in Figure 7) left by indicating, and correct lifting is dumped order and is rear box A → preceding casing B → middle casing C.

With rear box A lifting is example (as shown in Figure 5), settle 8 all to open machine insurance earlier, again the handle 55 of the front and back case switch 54 on the operation control panel 44 is turned round to the right by indicating, power supply is from storage battery or chassis power supply, electric signal is opened rear cabinet change-over valve 29 by front and back case switch 54, pressure gas flows in the air chamber 45 of the automatic case unpacking machine structure 10 that is attached thereto by rear cabinet change-over valve 29, by air chamber push rod 48, push rod bearing pin 49 promotes latch hook 51 and rotates around latch hook bearing pin 53, bill unclamps box board connector 50 is opened, and bottom-open type chamber door 5 is opened with certain angle under the deadweight effect.Gas circuit between rear cabinet change-over valve 29 and the automatic case unpacking machine structure 10 is through a rear cabinet check valve 32 be connected with manual air valve 33 (as shown in Figure 5).When needing rear box A to unload under steam, neutral switch 26 is turned round handle 55 to the right by indicating, then the handle 55 of power take-off valve 57 is turned round to the right by indicating, power takeoff 40 fluid,matching press pumps 41 are started working.Hydraulic oil is through lifting valve 37 backflow hydraulic reservoirs 38.The spool of the promotion of the pressure gas in gas circuit rear cabinet change-over valve 29 makes it commutation between rear cabinet check valve 32 and automatic case unpacking machine structure 10 simultaneously.When needing lifting rear box A, the handle 55 of lifting switch 58 indicates by lifting and turns round left, pressure gas enters lifting valve 37 and promotes spool, hydraulic oil enters the hydraulic lifting cylinder 20 of rear box A through rear cabinet change-over valve 29, the cylinder bar stretches out, promote the last lifting base plate 18 of rear box A, lifting base plate 21 upwards liftings down, begin to dump material.Simultaneously chamber door stay bearing plate 22 is propped up bottom-open type chamber door 5, makes that goods is easier to be dumped.When being lifted to end position, last lifting base plate 18, following lifting base plate 21 form the intermediate projections approximate equicrural triangle of two sides bevelled to the left and right with centre joint Antileaking plate 16, and hydraulic oil is back to hydraulic reservoir 38 by by pass valves in the lifting valve 37.In the middle stopping time, the handle 55 of lifting switch 58 places meta.During decline, the handle 55 of lifting switch 58 is turned round to the right, hydraulic oil in the hydraulic lifting cylinder 20 is back to hydraulic reservoir 38 through rear cabinet control oil change-over valve 35, lifting valve 37 under the effect of lifting base plate deadweight, bottom-open type chamber door 5 returns to the sagging position of closing of nature, finishes the lifting of rear box A is dumped.

When preceding casing B lifting is dumped, handle 55 left sides of front and back case switch 54 are turned round, and electric signal is opened preceding case change-over valve 28, and pressure gas enters manual air valve 33 through preceding case check valve 31, one the tunnel enters automatic case unpacking machine structure 10 opens bottom-open type chamber door 5, and one the tunnel enters preceding case change-over valve 28 makes it commutation.Before during casing B lifting, the handle 55 of lifting switch 58 is turned round to the right, pressure gas enters lifting valve 37 and promotes spool, the hydraulic lifting cylinder 20 of hydraulic oil casing B before rear cabinet control oil change-over valve 35, preceding case control oil change-over valve 34 enter, make the cylinder bar stretch out the following lifting base plate 21 of the preceding casing B of promotion, upward lifting base plate 18 upwards liftings, begin to dump material, course of action is with above-mentioned rear box A dumping process.At last, bottom-open type chamber door 5 returns to the sagging position of closing of nature, finishes the lifting of preceding casing B is dumped.

Casing C lifting is dumped in last.Handle 55 right sides of raising middle flask switch 56 are turned round, and electric signal is opened raising middle flask change-over valve 27, and pressure gas enters manual air valve 33, a tunnel through raising middle flask check valve 30 and enters automatic case unpacking machine structure 10 bottom-open type chamber door 5 is opened.During casing C lifting, the handle 55 of lifting switch 58 is turned round to the right, pressure gas enters lifting valve 37 and promotes spool, the hydraulic lifting cylinder 20 of hydraulic oil casing C in rear cabinet control oil change-over valve 35, preceding case control oil change-over valve 34 enter, the cylinder bar is stretched out, the following lifting base plate 18 of casing C, upward lifting base plate 21 upwards liftings, inclination begin to dump material in the promotion, and course of action is with the dumping process of above-mentioned rear box A, preceding casing B.At last, bottom-open type chamber door 5 returns to the sagging off position of nature, finishes the lifting of centering casing C and dumps.

After the contained material of whole container dumps and finishes, the handle 55 of power take-off valve 57 is turned round left, power takeoff 40 disconnects, and Hydraulic Pump 41 quits work.At last, bottom-open type chamber door 5 is closed, hang up properly each position mechanical safety 8, finish whole container self-dumping working cycle.

Aforesaid power take-off valve 57, lifting switch 42 can be monomers independently; Also can make up as a whole.Automatically the switch 25 of unpacking can only be opened one by one by the lifting order of rear box A, preceding casing B, middle casing C, can not open two simultaneously.The utility model has been realized automatically unpacking effectively, unloading automatically, and can drive-through dumping, has obviously improved unloading and conveying efficiency, and convenient, laborsaving, the safety of whole unloading process has been accelerated vehicle operation and logistics and had enough to meet the need.The utility model can be supporting with tip-up lorry, is widely used in transportation, the self-unloading of various loose unpacked materials.
