Description

Technical Field

[0001] The utility model relates to the field of waste treatment, in particular to a tailgate opening and closing driving mechanism of a vertical garbage compression system. Background Art

[0002] With the rapid development of urbanization, the treatment of urban domestic and industrial waste has become a pressing challenge in this field. In waste transfer and landfill, waste must be compressed into blocks before being transported by waste transfer vehicles and processed. In the field of waste compression, two types of equipment are typically involved: a garbage compactor, which primarily compresses the waste, and a garbage unloading device, which unloads the waste into the garbage compactor. The following describes these two types of equipment in the prior art.

[0003] In the prior art, garbage compactors can be divided into horizontal compression type and vertical compression type according to compression direction, and can be divided into direct compression type and pre-compression type according to working principle. Here we mainly discuss the vertical compression type garbage compactor.

[0004] The vertical compression type garbage compactor consists of a vertical steel frame, a flip chute installed on the vertical steel frame, and a rotary clamping mechanism. The vertical steel frame is installed in the garbage compression station. The garbage compression station includes an upper site and a lower site. The vertical steel frames are distributed in the upper site and the lower site. The rotary clamping mechanism is hinged to the upper site.

[0005] After the transfer vehicle carrying the container enters the lower yard, it reverses into the garbage compression station. The hydraulic lifting system on the transfer vehicle lifts the container so that it stands upright in the garbage compression station. The rotary clamping mechanism rotates to form a circle around the container. The rotary clamping mechanism works to clamp the container so that the container is centered. The tailgate lock on the container is unlocked. After the tailgate of the container is opened, the flip chute flips over. One end of the flip chute cooperates with the open door end of the container. The garbage unloading truck driving on the upper yard reverses to the garbage unloading port. The hydraulic system on the garbage unloading truck lifts the garbage loading box. The garbage in the garbage loading box pours into the flip chute, and the garbage flows into the container along the chute. This vertical compression type garbage compactor has the following defects:

[0006] After the lock on the container unlocks the tailgate, the tailgate must be rotated by a dedicated tailgate opening and closing drive mechanism to expose the opening of the container body. The structure of the currently used tailgate opening and closing drive mechanism is relatively complex and costly. Utility Model Content

[0007] The utility model provides a tailgate opening and closing driving mechanism of a vertical garbage compression system with a simple structure and low cost.

[0008] The technical solutions to the above technical problems are as follows:

[0009] The tailgate opening and closing drive mechanism of the vertical garbage compression system includes a fixed seat, a second swinging drive component, a second swing arm, and a plug-in unit that cooperates with the tailgate. The fixed seat is used to be fixed to the vertical frame. The fixed seat is provided with a receiving slot. The second swing arm cooperates with the receiving slot. The second swinging drive component is installed on the fixed seat. The power output end of the second swinging drive component is connected to one end of the second swing arm, and the plug-in unit is installed at the other end of the second swing arm.

[0010] In the present invention, the plug-in unit and the second swing arm can be hidden in the receiving groove on the fixing base, which not only saves installation space but also reduces the volume of the entire tailgate opening and closing drive mechanism. In addition, the fixing base and the vertical frame are fixed as one body, so that the entire tailgate opening and closing drive mechanism is fixed on the vertical frame. Therefore, during actual installation and use, only the space of the vertical frame needs to be occupied. Therefore, the present invention is not only simple in structure, but also reasonably utilizes the vertical frame, so that the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0022] like Figures 1 to 7 As shown, the tailgate opening and closing drive mechanism A of the vertical garbage compression system of the present invention includes a fixed base 11, a second swinging drive component 12, a second swing arm 13, and a plug-in unit cooperating with the tailgate W. The fixed base 11 is used to be fixed to the vertical frame B. The fixed base 11 is provided with a receiving groove 11a. The second swing arm 13 cooperates with the receiving groove 11a. The second swinging drive component 12 is installed on the fixed base 11. The second swinging drive component 12 can adopt a hydraulic motor or an electric motor. The power output end of the second swinging drive component 12 is connected to one end of the second swing arm 13. The plug-in unit is installed at the other end of the second swing arm 13. The plug-in unit is used to plug with the tailgate W.

[0023] In this embodiment, the container consists of a garbage storage box L and a tailgate W that cooperates with the opening of the garbage storage box L. One end of the tailgate W is hinged to the garbage storage box L. The garbage storage box L is provided with a lock (the lock belongs to the prior art and is not shown in the figure). The lock is used to lock the other end of the tailgate W. When the lock releases the lock on the tailgate W, the tailgate W is driven to rotate by the tailgate opening and closing drive mechanism A, thereby exposing the open end of the garbage storage box L.

[0024] There is a vertical shaft C in the vertical frame B, and the garbage container L is placed on a lifting and transporting assembly (not shown in the figure). The lifting and transporting assembly consists of a hydraulic drive and a bracket. The container can be raised and lowered in the vertical shaft C through the lifting and transporting assembly.

[0025] The fixed seat 11 includes a first seat body 11b, a panel 11c, and a second seat body 11d. A clearance space 11e is provided on the first seat body 11b. The panel 11c is fixed to the first seat body 11b. An opening 11f is provided on the panel 11c. In this embodiment, the clearance space 11e is located below the panel 11c, and the opening 11f is L-shaped. Since the garbage holding box L or the transfer vehicle or the garbage unloading vehicle will pass through the panel 11c, the clearance space 11e does not penetrate the first seat body 11b in the horizontal and / or vertical direction, and the opening 11f does not penetrate the panel 11c in the horizontal and / or vertical direction. In this way, the strength of the fixed seat 11 can be guaranteed and is sufficient to support the vehicle or the garbage holding box L. The opening 11f and the clearance space 11e on the first base body 11b constitute the accommodating groove 11a. The second base body 11d is located in the clearance space 11e. The second base body 11d is fixed to the first base body 11b. The second swing driving component 12 is fixed to the second base body 11d.

[0026] The plug-in unit includes a linear drive 14, a first sleeve 15, a first pin 16, and a second sleeve 17. The linear drive 14 is connected to the first sleeve 15, the first pin 16 is fixed to the first sleeve 15, the second sleeve 17 is sleeved on the first sleeve 15, and the second sleeve 17 is slidably fitted with the other end of the second swing arm 13.

[0027] The second sliding sleeve 17 is provided with a forward blocking portion and a backward blocking portion for the first sliding sleeve 15. When the first sliding sleeve 15 is pushed to a certain position by the linear drive 14, it is blocked by the forward blocking portion, so that the second sliding sleeve 17 moves forward together with the first sliding sleeve 15. When the first sliding sleeve 15 is pulled back to a certain position by the linear drive 14, it is blocked by the backward blocking portion, so that the second sliding sleeve 17 moves backward together with the first sliding sleeve 15. The distance between the forward blocking part and the backward blocking part is greater than the length of the first sliding sleeve 15. Whether the first sliding sleeve 15 moves forward or backward, it needs to move a certain distance before it can contact the forward blocking part or the backward blocking part. The advantage of this structure is: from the above description, it can be seen that the accommodating groove 11a will not penetrate the horizontal and / or vertical direction of the fixed seat 11. Therefore, the length of the accommodating groove 11a is limited, and the length of the plug-in unit is thereby limited. When the plug-in unit adopts a structure composed of a linear drive 14, a first sliding sleeve 15, a first latch 16, a second sliding sleeve 17, a forward blocking part and a backward blocking part, it is equivalent to forming a multi-stage telescopic structure. This multi-stage telescopic structure makes up for the limitation of the assembly space on the length of the plug-in unit, so that the plug-in unit can be smoothly combined with the tailgate W.

[0028] Preferably, the second sliding sleeve 17 is provided with a first baffle 17a and a second baffle 17b for cooperating with the first sliding sleeve 15, the first baffle 17a is the forward blocking portion, the second baffle 17b is the backward blocking portion, the first sliding sleeve 15 is located between the first baffle 17a and the second baffle 17b, and the distance between the first baffle 17a and the second baffle 17b is greater than the length of the first sliding sleeve 15.

[0029] The second swing arm 13 includes a swing arm body 13a, a connecting sleeve 13b, and a sleeve 13c. One end of the swing arm body 13a is fixed to the sleeve connecting sleeve 13b, and the other end of the swing arm body 13a is fixed to the sleeve 13c. The plug-in unit is installed in the sleeve 13c, that is, the linear drive 14, the first sliding sleeve 15, and the second sliding sleeve 17 are located in the sleeve 13c, and the sleeve 13c is fixed to the second swing drive component 12.

[0030] The tailgate opening and closing drive mechanism A further includes a support seat 18 and a roller 19 for squeezing the garbage storage box L to center the garbage storage box L. The support seat 18 is fixed to the fixing seat 11, and the roller 19 is rotatably matched with the support seat 18.

[0031] Since the garbage holding box L is not necessarily in a centered position when it is released onto the lifting and transporting assembly by the transfer vehicle, when the lifting and transporting assembly drives the garbage holding box L to descend and opens the tailgate W, the chute assembly (the chute assembly is hinged on the vertical frame B, and the chute assembly is not shown in the figure) used to receive and guide the garbage rotates. Since the chute assembly can only perform rotational movement, the chute assembly cannot move in the front, back, left and right directions of the garbage holding box L. Therefore, if the position of the garbage holding box L does not correspond to the chute assembly, the chute assembly is likely to be unable to be inserted into the interior of the garbage holding box L.

[0032] In the present invention, the roller 19 squeezes the garbage holding box L to center the garbage holding box L, so that the front and rear positions of the garbage holding box L on the lifting and transporting assembly are centered, so that the chute assembly can enter the garbage holding box L after rotation.

[0033] The working process of this utility model is as follows:

[0034] The container is released onto the lifting and transporting assembly through a hydraulic mechanism (not shown in the figure), and the lifting and transporting assembly drives the garbage holding box L to descend. During this process, the outer wall of the garbage holding box L is squeezed by the roller 19, causing the garbage holding box L to move, and then the garbage holding box L is centered in the front and rear positions of the lifting and transporting assembly.

[0035] After the garbage container L descends to the designated position, the lock on the tailgate is released, and the linear actuator 14 in the tailgate opening and closing drive mechanism A activates, driving the first sliding sleeve 15 toward the tailgate W. When the first sliding sleeve 15 contacts the first baffle 17a, the first sliding sleeve 15 drives the second sliding sleeve 17 to move, ultimately inserting the first latch 16 into the slot on the tailgate W. The second swing drive component 12 then rotates forward, driving the second swing arm 13 to rotate. This, in turn, drives the plug-in unit and the tailgate W to rotate, exposing the opening in the garbage container L.

[0036] When the garbage container L is filled with garbage, the second swing drive component 12 reverses, and the tailgate opening and closing drive mechanism A drives the tailgate W to reverse, closing the opening of the garbage container L. The lock locks the tailgate W, and the lifting and transporting assembly drives the garbage container L up the shaft C to the designated position.
