Description

Cover door mechanism and buried garbage bulk loading machine

Technical Field

The invention relates to a cover door mechanism for a discharge hole and a buried garbage bulk loader comprising the same.

Background

In the course of material transfer, transfer stations for temporarily storing the material are usually provided. For example, in the field of coal transportation, coal from various places is generally collected in silos as temporary storage of coal, and the coal stored in the silos is then transported to a destination. For another example, in the field of waste disposal, a waste transfer station is generally provided in a location adjacent to a residential area, and waste in waste bins within a peripheral area is first collected at the waste transfer station and then transferred from the waste transfer station to a waste disposal plant.

In the field of garbage disposal, a buried garbage compressor is often designed at present, wherein a pit is dug at a preset position, a garbage compressor supported by a lifting mechanism is arranged in the pit, a closable feed inlet is arranged at the top of the garbage compressor, a compression mechanism is arranged inside the garbage compressor, and a closable discharge outlet is arranged on the side part of the garbage compressor. When needing to load rubbish, lifting mechanism retracts and makes the rubbish compressor fall into the pit, opens the feed inlet at top simultaneously, loads into the rubbish material, then carries out compression treatment by inside compression mechanism to rubbish. When the garbage needs to be transported away, the lifting mechanism is lifted, the garbage compressor is lifted to the ground, the discharge port is opened, and the compressed garbage materials are pushed out from the discharge port by the aid of the internal compression mechanism.

In such a conventional buried trash compactor, the discharge port is provided with a capping door. The traditional cover sealing door has two forms, the first form is a gate which moves vertically, when the gate moves upwards, the discharge hole is opened, and when the gate falls to the lowest position downwards, the discharge hole is closed; the second form is a hinged door hinged to the top of the discharge hole, which can be opened or closed by a driving device such as a hydraulic cylinder.

However, the main problem of the closing door in the form of a gate is that it is not tight sealed, which easily causes the dirt in the tank to flow to the outside; while hinged doors tend to interfere with transit vehicles by remaining attached to the cabinet in the open position.

In view of the above, it is desirable to provide a sealing door with a better sealing effect and less interference.

Compared with the traditional garbage transfer system, the invention systematically provides an integral solution, wherein corresponding technical improvements are provided for the garbage bulk loader and the garbage loading and unloading vehicle matched with the garbage bulk loader. In the following detailed description, the respective mechanisms of the garbage bulk machine are described separately, and aspects of the technical solution of the present invention are described in detail.

In addition, the technical scheme of the invention is suitable for the fields of storage or transportation of various materials, such as coal, grain and the like, although the invention is mainly described by taking garbage materials as an example in the specific implementation mode. It can be understood that the solution of the invention is particularly suitable for the storage and transport of waste material.

1 garbage bulk machine

The main function of the garbage bulk loader is to temporarily store garbage materials, so that the garbage bulk loader needs to be conveniently loaded with the materials and unloaded with the materials. As shown in fig. 1 to 3, the garbage bulk loader includes a box 10, a feeding port 11 capable of being closed is arranged at the top of the box 10, a discharging port 12 capable of being closed is arranged at the front end of the box 10, when the garbage bulk loader is located in a pit, the discharging port 12 is always kept in a closed state, and when the garbage bulk loader needs to be filled with materials, the feeding port 11 is only required to be opened. The garbage bulk loader is not provided with a power source or a power supply, the power source can be motive power provided by a motor or an internal combustion engine for an actuating mechanism or pressure hydraulic oil provided by a hydraulic motor, and the power supply can be electric power supplied by the motor. And the waste bulk machine further comprises a closure door arrangement, as shown in figure 2, comprising a closure door 13 for the outlet 12 and an operating mechanism operable to connect the closure door 13 to the frame.

In the conventional garbage bulk loading machine, since the garbage bulk loading machine needs to operate to open and close the material inlet and the material outlet, a driving device is usually provided for realizing, and a power source or a power source of the driving device is usually self-contained. In other words, the waste bulk loader has its own dedicated power source or power source. However, when the working environment of the garbage bulk loader is poor, the power source or the power supply is inevitably affected, and the working reliability is affected.

Different from the traditional garbage bulk loading machine, in the technical scheme of the invention, the garbage bulk loading machine breaks through the conventional thought in the field and does not have a self-contained power source or power supply, but borrows the power source or power supply of other devices (such as a garbage loading and unloading vehicle) matched with the garbage bulk loading machine for use as shown in the following. Therefore, the power source or the power supply of the garbage bulk loader is separated from the specific environment of the garbage bulk loader, so that the garbage bulk loader is basically not influenced by the adverse effect of the working environment of the garbage bulk loader, and the working reliability is improved.

As shown in fig. 1 and 2, the garbage bulk loader of the present invention may be a buried type garbage bulk loader vertically movably supported by a lifting mechanism 200, and the lifting mechanism 200 is powered by a lifting cylinder 201, but is not limited thereto. The garbage bulk loader has a connection means for connecting with other power sources and/or power sources outside, for example, as shown in fig. 1, the connection means may be a connection oil pipe and an electric wire 600, the connection oil pipe and the electric wire 600 is placed outside the pit and can be electrically connected with a plug nearby, or the electric wire 600 can be electrically connected with the garbage truck 400, and the garbage truck 400 can be further provided with a control box 700. After the garbage bulk loader is filled with materials, the garbage bulk loader and the garbage loading and unloading vehicle 400 are connected by using a connecting oil pipe and an electric wire 600, so that the garbage bulk loader obtains power (electric power-driven mechanical power and pressure hydraulic oil-driven mechanical power). Meanwhile, the control box 700 is operated, so that the lifting mechanism 200 is vertically lifted under the action of the lifting oil cylinder 201 until the opening 401 of the garbage loading and unloading truck 400 is in butt joint with the discharge hole 12 of the garbage bulk loader.

Hereinafter, the cover closing door device, the sliding door mechanism and the pushing mechanism of the garbage bulk loader of the present invention will be described in order.

1.1 capping door device

The operating mechanism of the closing door device is capable of switching the closing door 13 between a closing position for hermetically closing the discharge port 12 and an opening position for separating and opening the discharge port 12, and in the opening position, the closing door 13 and the discharge port 12 are disconnected from each other with a space therebetween. In a preferred case, the garbage bulk loader is arranged in the pit 300 movably up and down supported by the lifting mechanism 200, and the capping door 13 is switched from the closed position to the open position to achieve discharging when the garbage bulk loader is lifted up to the ground by the lifting mechanism 200. In the closed position, the closure door 13 sealingly closes the discharge opening 12 to prevent material (e.g., refuse) in the container from falling out. It is further preferred that the cover door 13 sealingly covers the spout 12 to prevent liquid from flowing out of the interior.

The operating mechanism may be mounted or attached to a frame that provides a foundation for the operating mechanism. The housing may take many forms. For example, the housing may be independent of the spout 12, with an operating mechanism mounted to the housing independent of the enclosure 10, the operating mechanism being capable of allowing the closure door 13 in the closed position to move synchronously with the movement of the enclosure 10. When the container 10 moves up and down, the flap door 13 can be held in the closed position while moving with the container 10 under the control of the operating mechanism. For example, the housing may be disposed on an interior wall of the pit 300 and the operating mechanism may be a robotic arm structure. However, the present invention is not limited thereto, and as shown in fig. 1 and 2, the frame may be a box 10 where the discharge hole 12 is located, which is also a preferred embodiment provided by the present invention, and the operating mechanism is disposed on the box 10.

Specifically, as shown in fig. 2 to 4, the operating mechanism preferably includes a driver 14 and a slider arm 15. One end of the actuator 14 is hinged to the side of the container 10, and the actuator 14 may be a hydraulic cylinder, but is not limited thereto. The front end 151 of the slide arm 15 is fixedly provided with the cover door 13, and the rear end 152 of the slide arm 15 is hinged to the other end of the actuator 14. The slide arm 15 is further provided with a hinge end 153 between the front end and the rear end, the hinge end 153 is slidably and hingedly disposed at the side of the case 10, and an obtuse angle is formed between the extending direction of the slide arm 15 from the hinge end 153 to the front end 151 and the extending direction from the hinge end 153 to the rear end 152, and preferably, the obtuse angle is 100 degrees to 160 degrees.

Thereby, the cover door device first moves in the front-rear direction toward the discharge port 12, and the cover door 13 horizontally separates from the discharge port 12; after the hinged end 153 moves a predetermined distance, the cover door device revolves around the hinged end 153 as a rotation center under the continuous action of the driver 14, and the cover door 13 is separated from the discharge hole 12 in the vertical direction.

Wherein, a guide groove (not shown) may be provided at a side of the case 10, and the hinge end 153 is slidably restricted in the guide groove, and the slide arm 15 can move along the designed track by the driver 14.

Further, as shown in fig. 5, the driver 14 and the sliding arm 15 may be respectively symmetrically disposed at a pair of both side surfaces of the case 10, and the closing door 13 is fixedly connected to both sliding arms 15 to improve the balance and structural stability of the closing door apparatus.

Further, as shown in fig. 3, both side surfaces of the cabinet 10 may be provided with the first guide 16 and/or the second guide 17. The first guide member 16 is used to guide each of the slide arms 15 to move in the front-rear direction, for example, a guide rail may be formed on a side wall of the case 10 in the front-rear direction, and the first guide member 16 is fixedly connected to the slide arm 15 and can move along the guide rail, so that the slide arm 15 moves along the designed track. The second guide 17 serves to restrict each slide arm 15 from wobbling in the lateral direction.

In addition, as shown in fig. 3, the discharge port 12 is preferably vertically arranged, and in the open position, the cover door 13 is higher than the top of the discharge port 12, so that the opening 401 of the garbage truck 400 is smoothly abutted with the discharge port 12 of the garbage bulk loader, and the cover door 13 does not interfere with the garbage truck.

Preferably, as shown in fig. 2 and 3, a top cover plate 18 for covering or opening at least a portion of the inlet 11 is provided at the top of the case at a position adjacent to the outlet 12. The top cover 18 may be hingedly or slidably attached to the housing 10. The top cover plate 18 is a feeding channel, the garbage bulk loader fills garbage materials into the box body 10 through the top cover plate 18, and under the protection of the top cover plate 18, the load of the vertical direction of the garbage bulk loader cannot be transmitted to the sealing cover door 13, so that the effect of protecting the sealing cover door 13 is achieved.

In addition, in the conventional garbage bulk loader, particularly in the buried garbage bulk loader, the liquid garbage often leaks into the pit 300 through the discharge port 12 side, thereby polluting the environment in the pit 300 and causing a bad odor phenomenon. For this purpose, as shown in fig. 3 and 4, a first seal can be arranged on the end face of the spout 12 around the spout 12, against which first seal the closure door 13 closing the spout 12 is pressed in the closed position. In order to further improve the sealing performance, a second sealing member 20 may be provided on the cover door 13 to cooperate with the first sealing member. The first and second sealing members may be rubber sealing rings or gaskets, but the present invention is not limited thereto.

1.2 sliding door mechanism

The garbage bulk machine further includes a sliding door mechanism, as shown in fig. 6 to 10, which includes a sliding door 30, the sliding door 30 is slidably provided to the feeding port 11 of the casing 10 for storing the materials, and the sliding door 30 adjustably covers the feeding port 11 at an outer side of the feeding port 11. In addition, the sliding door 30 may be horizontally arranged in the front-rear direction (may be obliquely arranged). Preferably, the sliding plane of the sliding door 30 is disposed in parallel with the lengthwise extension direction of the cabinet. Conventionally, the material inlet 11 is covered by a turnover door, but the turnover door has a heavy weight and is very laborious to turn over, and a fixing device is required to fixedly close the door, compared with the sliding door 30 of the present invention, which can open the material inlet 11 only by simple sliding.

As shown in fig. 6 and 9, at least one handle 370 is provided on an outer surface of the sliding door 30 for an operator to move the sliding door 30. Preferably, four handles 370 may be provided at four corners of the sliding door 30, but is not limited thereto.

Specifically, as shown in fig. 6 to 10, the sliding door mechanism includes rails 32, the rails 32 being arranged at intervals in parallel to each other along the edge of the material inlet 11 outside the material inlet 11, the sliding door 30 being slidably provided on the rails 32. Further, as shown in fig. 9 and 10, the sliding door 30 is connected to the rail 32 by a rolling bearing 301 to reduce friction when the sliding door 30 moves, so that a worker can operate the sliding door with less effort. In addition, a buffer member 302 may be further provided on the periphery of the sliding door 30 for buffering the impact during the movement, and the buffer member 302 may be a weather strip. The sliding of the sliding door 30 is realized by the rail structure, but the invention is not limited thereto, and the sliding of the sliding door 30 can be realized by installing rollers on the side edges of the sliding door 30, and the rollers can be one-way wheels or universal wheels.

In addition, each track 32 has a U-shaped cross-sectional shape (see fig. 8 and 11) opening toward the other track 32, with one side of the sliding door 30 slidably confined within the U-shaped opening of one track 32 and the other side of the sliding door 30 slidably confined within the U-shaped opening of the other track 32. In addition, when the sliding door 30 is coupled in the rail 32 by the rolling bearing 301, the rolling bearing 301 is also disposed in the U-shaped opening. Through the U-shaped structure, can realize spacing to sliding door slidable.

In addition, in order to prevent the sliding door 30 from sliding by itself to open the material inlet 11 and to lock the sliding door at a predetermined position, the sliding door mechanism further includes a locking device 31, and the locking device 31 is disposed on the casing 10 at a position adjacent to the material inlet 11 to releasably lock the sliding door 30 to the casing 10, but the present invention is not limited to a specific structure of the locking device 31 as long as the locking action of the sliding door 30 can be performed, and hereinafter, a preferred structure of the locking device 31 provided by the present invention will be described.
