Description

Technical Field

[0001] The invention belongs to the technical field of special vehicles and garbage disposal, and in particular relates to a rapid transposition mechanism for a transposition door of a garbage compression station, and a transposition method. Background Art

[0002] Garbage compression stations compress the garbage collected by sanitation vehicles into a smaller volume, and then the transfer vehicles transport the compressed garbage to the garbage treatment plant for landfill, incineration or composting. In existing compression stations, the garbage station is equipped with a gate mechanism, which will only drop after the pressure head device exits. Due to the time difference, garbage accumulates in front of the pressure head device. After the gate mechanism is closed, part of the garbage will remain between the pressure head device and the transfer vehicle, causing secondary pollution.

[0003] Chinese patent application number CN200620111321.X discloses a container closure device for loading garbage. In this patent, when changing positions, the upper and lower latches need to be docked with a total of 6 docking holes of the upper and lower baffles respectively, and the positioning points are numerous and complex, the alignment is difficult, and the reliability is poor.

[0004] Chinese patent application number CN201621049494.3 discloses a transposition structure of a transposition door. In the patent, during transposition, the press-fit device on the push plate needs to be docked with the docking hole of the sealing plate. During long-term use, the press-fit device frequently hits the docking hole, which easily causes the docking hole to deform and eventually makes it impossible to transpose. Summary of the invention

[0005] In view of the above problems, the present invention aims to provide a transposition mechanism and method for a transposition door of a garbage compression station which has a simple structure and reliable operation, and can realize rapid transposition of the transposition door.

Second docking holes are respectively provided on the left and right sides of the rear door frame of the compressor, and third docking holes are provided at intervals on the left and right sides of the front of the pressure head device; the plug of the locking fork mechanism can move outward and be inserted into the second docking hole to realize the docking of the transposition door with the rear door frame of the compressor, and the plug of the locking fork mechanism can also move inward and be inserted into the third docking hole to realize the docking of the transposition door with the pressure head device, thereby realizing the rapid transposition of the transposition door.

[0007] As a preferred embodiment of the above scheme, the lock fork mechanism includes two horizontal rods spaced apart from each other, two vertical blocks spaced apart from each other between the two horizontal rods, the two horizontal rods and the two vertical blocks together form the pull groove, and the two ends of the horizontal rods constitute the plugs of the lock fork mechanism; accordingly, the number of the first docking holes, the second docking holes, and the third docking holes matches the number of the plugs. The lock fork mechanism using a frame structure automatically forms the pull groove, and there is no need to process the pull groove separately. The lock fork mechanism has a simple structure, reliable performance, and low manufacturing cost.

[0008] More preferably, the plug is in a polygonal pyramid shape, and the number of the pyramids is at least three. The use of a polygonal pyramid structure plug facilitates the plug to be quickly and accurately inserted into or removed from the docking hole, and can ensure that the gap is small after being inserted into place.

[0009] More preferably, the diameter of the horizontal rod matches the diameter of the first docking hole, the second docking hole, and the third docking hole and is loosely matched, and the first docking hole, the second docking hole, and the third docking hole are embedded with a reinforcing sleeve. The reinforcing sleeve is added to avoid repeated insertion and severe wear at the docking hole position, and only the reinforcing sleeve needs to be replaced after wear.

[0011] Further preferably, the pressure head device is also provided with a slide rail to guide the left and right movement of the transposition shifting block to ensure that the transposition shifting block moves smoothly left and right.

[0012] Further preferably, the above-mentioned rapid shifting mechanism of the shifting door of the garbage compression station also includes a proximity switch or a travel switch sensor, which is correspondingly arranged at the predetermined position where the shifting block moves to the outside and the inside.

[0014] S1, in the initial state, the shift door is combined with the rear door frame of the compression box, the compression box enters the predetermined compression position, and then the left and right driving mechanisms of the two shift blocks respectively drive their corresponding shift shift blocks to move outwards, and when the shift shift blocks move to the predetermined positions, the left and right driving mechanisms of the shift shift blocks stop moving, and at this time, the shift shift blocks are just behind the shift slots of the lock fork mechanism;

[0015] S2, the front and rear driving mechanism of the pressure head drives the pressure head device to move forward until it reaches the docking position and stops moving. At this time, the shifting block is just inserted into the shifting groove of the locking fork mechanism;

[0016] S3. The left and right driving mechanisms of the two shift blocks respectively drive their corresponding shift shift blocks to move outward, thereby driving the lock fork mechanism to move inward. During the movement, the plug of the lock fork mechanism is separated from the second docking hole of the rear door frame of the compression box and inserted into the third docking hole of the pressure head device, thereby realizing the rapid shifting of the shift door.

[0017] The beneficial effects of the present invention are as follows: in the initial state, the lock fork mechanism is docked with the transposition door, and the rear door frame of the compression box and the transposition door are integrated through the lock fork mechanism; when the compression box reaches the predetermined compression position, the left and right driving mechanisms of the shift block move the transposition shift block outward to the predetermined position, and the front and rear driving mechanisms of the pressure head drive the pressure head device forward. After advancing to the predetermined position, the transposition shift block is just located in the shift slot inserted into the lock fork mechanism, and the left and right driving mechanisms of the shift block drive the transposition shift block to retreat inward, and at the same time, the transposition shift block drives the lock fork mechanism to move inward, so that the lock fork mechanism is separated from the rear door frame of the compression box, until the transposition door and the pressure head device are integrated through the lock fork mechanism, and the transposition action is completed. The present invention has the characteristics of simple structure, reliable operation, fast transposition, low cost and later maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS
