Referring to fig. 1-2, a door sealing device of a garbage truck comprises a carriage body 1, wherein the carriage body is provided with an inner cavity for accommodating garbage, the upper end of the carriage body is provided with a garbage inlet 2, the rear end of the carriage is provided with a garbage outlet, and the rear end of the carriage is provided with a door 3 for opening or closing the garbage outlet; the utility model discloses a car door, including carriage body, door, support lug, door, back fixed mounting, be provided with spout 5 on the support lug, the door is just to be provided with the breach to the both sides of support lug, breach department fixed mounting has slide bar 6 of sliding fit in the spout, the upper end fixed mounting of carriage body has and is used for carrying out the pushing mechanism who promotes to the door, the both sides of carriage body still are provided with and are used for driving the door and carry out the tilting mechanism that overturns, the rear end lateral wall indent of carriage body forms rectangle annular groove 7, the door is just to being provided with protruding 8 to rectangle annular groove, fixed mounting has the sealing washer in the rectangle annular groove.

Like this, when the carriage body needs splendid attire rubbish, pour rubbish into the inner chamber through the rubbish entry, transport rubbish back in the refuse dump with the garbage truck, need open the door to the jacking cylinder through the installation on the garbage truck drives the carriage body upset, makes rubbish pour in the garbage truck.

Specifically, when splendid attire rubbish, the protruding card of door is gone into in the rectangle annular groove of carriage body rear end to be provided with the sealing washer, can guarantee the sealed to rubbish, avoid rubbish to flow out from between door and the carriage body. When the vehicle door is opened, the sliding rod driving the vehicle door through the pushing mechanism and the turnover mechanism moves along the sliding groove, so that the protrusion moves to the outer side of the rectangular annular groove, the turnover mechanism continues to act to drive the vehicle door to turn over, sealing can be guaranteed when the vehicle door is required to be sealed, and interference is avoided when the vehicle door is required to be opened. When the vehicle door needs to be closed, the turnover mechanism drives the vehicle door to move to a vertical state, then the vehicle door is driven to reset through the turnover mechanism and the pushing mechanism, and the protrusion is clamped into the rectangular annular groove.

The pushing mechanism comprises a pushing cylinder 9 fixedly mounted at the upper end of the carriage body, a piston rod of the pushing cylinder is horizontally arranged and is fixedly provided with a push plate 10, and a locking mechanism used for locking with a vehicle door is mounted on the push plate. The pushing cylinder pushes the push plate, and the vehicle door is pushed to move through the push plate. When the door needs to be driven to reset, the push plate is connected with the door through the locking mechanism, and then the door is driven to reset.

Wherein, the push cylinder is provided with 2. The vehicle door can be pushed to move better.

The locking mechanism comprises a first motor 11 fixedly mounted on the push plate, an output shaft of the first motor is horizontally arranged and penetrates through the push plate, a locking plate 12 is fixedly mounted on the push plate, and a locking hole allowing the locking plate to penetrate is arranged on the car door in a penetrating mode. First motor drives the lock plate and rotates to the level, and the push pedal is promoted to the actuating cylinder, drives the lock plate and passes the locking hole, then first motor drives the lock plate and rotates to vertical, realizes being connected of lock plate and door, and the electronic lock plate of first motor rotates to the level, and the piston rod shrink of promotion cylinder realizes the unblock of lock plate and door.

Wherein, tilting mechanism includes the box 13 of fixed mounting in carriage body both sides, the upper end opening of box sets up, rotate through the bearing in the box and install the lead screw, the outside fixed mounting of box has second motor 14, the output shaft of second motor passes the box with the one end fixed connection of lead screw, connect the cooperation soon on the lead screw to have the nut, the nut upwards fixed mounting has cylinder support 15, it has upset cylinder 16 to articulate on the cylinder support, the outside protrusion in the both sides that the door is relative is provided with connecting portion, the piston rod of upset cylinder pass through the hinged-support with connecting portion fixed connection. The second motor drives the lead screw to rotate, drives the turnover cylinder through the nut to move, realizes and promotes the cooperation of cylinder, and the extension length of the piston rod that promotes the cylinder promptly is the same with the displacement distance of nut, and the arch that drives the door breaks away from with the annular groove of rectangle of carriage body. Afterwards, the piston rod of the turnover cylinder extends out to drive the vehicle door to rotate, so that the vehicle door is opened, and garbage can be poured out from the garbage outlet.

The principle is as follows:
