[0030] The utility model provides a sealing and locking device for the rear door of a muck truck, comprising:

[0031] Carriage 1;

[0032] The carriage 1 is arranged on the vehicle and can be used for temporarily storing the slag;

[0033] A rear door 2 is provided at one end of the carriage 1;

[0034] The rear door 2 is hinged to the carriage 1 and can seal one end of the carriage 1;

[0035] A pair of vertical grooves 3 are formed on one end surface of the carriage 1 near the rear door 2;

[0036] A transverse groove 4 is formed on one end surface of the carriage 1, and both ends thereof are respectively connected to a pair of vertical grooves 3;

[0037] A pair of vertical plates 5 are provided on one end surface of the rear door 2 and are respectively plugged into a pair of vertical grooves 3;

[0038] One end surface of the vertical plate 5 is fixedly connected to one end surface of the rear door 2, and can be relatively fixed, and at the same time plugged into the vertical groove 3, the gap between the rear door 2 and the carriage 1 can be sealed to prevent the leakage of debris;

[0039] A horizontal plate 6 is provided on one end surface of the rear door 2 and is plugged into the horizontal groove 4;

[0040] One end surface of the transverse plate 6 is fixedly connected to one end surface of the rear door 2, so that it can be relatively fixed, and at the same time, it is plugged into the transverse groove 4, so that the gap between the rear door 2 and the carriage 1 can be sealed to prevent the leakage of debris;

[0041] The locking mechanism is arranged on the outer wall surface of the carriage 1 and is used to lock the rear door 2 .

[0042] Specifically, the locking mechanism includes:

[0043] A pair of fixing blocks 7 are respectively arranged on the outer wall surface of the carriage 1;

[0044] One end surface of the fixing block 7 is fixedly connected to the outer wall surface of the carriage 1 and can be relatively fixed;

[0045] A connecting frame 8 is disposed below the fixing block 7, and one end of the connecting frame is fixedly connected to the side wall of the rear door 2;

[0046] A plug hole 9 is formed in the connecting frame 8;

[0047] The latch 10 is slidably mounted in the fixing block 7 and plugged into the plug hole 9;

[0048] One end of the latch 10 is plugged into the plug hole 9, so that the fixing block 7 and the connecting frame 9 can be relatively fixed, and at the same time the rear door 2 can be kept fixed, and one end of the carriage 1 can be sealed to prevent the leakage of debris.

[0049] Specifically, it also includes;

[0050] The fixed shell 11 is disposed above the fixed block 7 and is fixedly connected to the side wall surface of the carriage 1;

[0051] The cylinder 12 is disposed in the fixed housing 11, and the telescopic end is fixedly connected to one end of the latch 10;

[0052] The cylinder 12 is fixed on the outer wall of the carriage 1 and can remain fixed. The fixed shell 11 can protect the cylinder 12 to prevent the falling debris from damaging the cylinder 12 when loading debris into the carriage 1. At the same time, the contraction of the telescopic end of the cylinder 12 can drive the latch 10 to move, so that one end of it is separated from the plug hole 9, and the locked rear door 2 is opened.

[0053] Specifically, a first slide plate 13 is provided in the vertical groove 3, and a plurality of first elastic members 14 are provided in the vertical groove 3. One end of the first elastic member 14 is fixedly connected to one end surface of the first slide plate 13, and the other end is fixedly connected to the inner wall surface of the vertical groove 3.

[0054] The first elastic member 14 is a compression spring, which can apply a force to the first slide plate 13 to make one end face of the first slide plate fit with one end face of the vertical plate 5. At the same time, when the carriage 1 is pouring the debris, the first elastic member 14 can drive the first slide plate 13 to move and seal the vertical groove 3 to prevent the debris from entering the vertical groove 3 and affecting the connection between the vertical plate 5 and the vertical groove 3.

[0055] Specifically, a second slide plate 15 is provided in the transverse groove 4, and a plurality of second elastic members 16 are provided in the transverse groove 4, one end of the second elastic member 16 is fixedly connected to one end surface of the second slide plate 15, and the other end is fixedly connected to the inner wall surface of the transverse groove 4;

[0056] The second elastic member 16 is a compression spring, which can exert a force on the second slide plate 15 so that one end surface of the second slide plate 15 fits with one end surface of the transverse plate 6. At the same time, when the carriage 1 dumps the debris, the second elastic member 16 can drive the second slide plate 15 to move, seal the transverse groove 4, and prevent the debris from entering the transverse groove 4 and affecting the connection between the transverse plate 6 and the transverse groove 4.

[0057] Working principle: When loading the slag, the telescopic end of the cylinder 12 extends to drive the bolt 10 to move, so that one end of the bolt is plugged into the plug hole 9, which can lock the rear door 2. At the same time, the vertical plate 5 is plugged into the vertical groove 3, and the horizontal plate 6 is plugged into the horizontal groove 4, which can seal the gap between the rear door 2 and the carriage 1 to prevent the slag from leaking when the slag is transported. When it is necessary to dump the slag in the carriage 1, the staff starts the cylinder 12 to shrink its telescopic end and drive the bolt 10 to move, so that the bolt 10 One end of the vehicle is disengaged from the plug-in hole 9, and the rear door 2 is opened. At this time, the staff controls the vehicle to flip the vehicle compartment 1 and open the rear door 2 at the same time, so that the slag can be dumped. When tilting, the first elastic member 14 can drive the first slide plate 13 to seal the vertical groove 3 to prevent the slag from entering the vertical groove 3 and affecting the insertion of the vertical plate 5 into the vertical groove 3. At the same time, the second elastic member 16 can drive the second slide plate 15 to seal the transverse groove 4 to prevent the slag from entering the transverse groove 4 and affecting the insertion of the transverse plate 6 into the transverse groove 4, bringing convenience to people.
