Description

Technical Field

[0001] This utility model relates to the field of mobile garbage compression boxes, specifically a garbage compression box that is easy to maintain. Background Technology

[0002] Currently, mobile garbage compactors are favored by various environmental protection departments and are widely used due to their ease of operation and low investment cost. When a mobile garbage compactor is working, its garbage hopper first pours garbage into the compaction chamber, and then a pusher pushes the garbage into the storage bin until the storage bin is full. However, because the pusher cylinder and its connecting pin of the mobile garbage compactor are constantly in a humid environment with corrosive gases, if grease is not applied to the connecting pin in a timely manner for maintenance, rapid wear can easily occur at the hinges at both ends of the pin and the pusher cylinder, as well as at the inner hole of the mounting base.

[0003] The existing method for inspecting and maintaining the hinges and mounting bracket inner holes of mobile waste compactors involves opening the access door located within the compactor, retracting the pusher to the rear of the compactor chamber, and then having maintenance personnel reach into the chamber through the access door to apply grease to the grease fittings on the hinges. Due to the cramped and confined space within the compactor chamber, applying grease is extremely inconvenient, and the hinges and mounting bracket inner holes at both ends of the pin shaft and pusher cylinder cannot be properly maintained, leading to frequent maintenance. Furthermore, disassembly and maintenance work inside the compactor chamber is not only difficult but also involves enduring the pungent odor from the waste. Utility Model Content

[0004] The technical problem this application aims to solve is to provide a garbage compactor that is easy to maintain. By providing an oil nozzle, oil passage, and oil groove on the pin, maintenance personnel can easily add grease to the pin. The grease flows out through the oil groove, so that the hinge and the inner hole of the mounting base connected to the pin are also coated with grease, thus improving the convenience of garbage compactor maintenance.

[0005] The specific technical solution of this application is as follows: a garbage compression box that is easy to maintain, including a compression chamber, a telescopic device inside the compression chamber, hinges at both ends of the telescopic device, a mounting seat corresponding to the hinges inside the compression chamber, the hinges being inserted into the mounting seat and connected by a pin; an oil passage is provided inside the pin, an oil groove is provided on the surface of the pin and communicates with the oil passage, and an oil nozzle is provided at the top of the pin and communicates with the oil passage.

[0006] Preferably, the oil groove is a spiral oil groove that surrounds the outer circumference of the pin.

[0007] Furthermore, an extension tube is connected to the nozzle, extending out of the compression chamber.

[0008] Furthermore, the outer surface of the compression chamber is provided with an inspection port near each pin. The inspection port also includes a cover, which is fixed to the inspection port by screws. The cover is provided with a filling hole that can be opened and closed, and the extension tube extends out from the filling hole.

[0009] More preferably, the compression chamber is a segmented telescopic type, and a stacked protective plate is provided above the compression chamber. A support frame is provided inside the compression chamber. The support frame is fixed to the smallest vertical section of the compression chamber. The width of the support frame is smaller than the width of the smallest vertical section of the compression chamber. The extension tube is fixed to the upper end of the support frame in the contraction direction.

[0010] Furthermore, the side wall of the compression chamber in the contraction direction is also provided with an openable and closable maintenance door, and the telescopic device consists of two intersecting hydraulic telescopic cylinders, one end of which is fixed to the side wall of the compression chamber maintenance door.

[0011] Preferably, the door frame of the inspection door is also provided with a first direct-pressure plunger type limit switch, which is fixed to the door frame by a mounting bracket.

[0012] Preferably, it further includes a hydraulic power chamber and a hydraulic power unit, the hydraulic power unit being slidably connected within the hydraulic power chamber, and a second direct-pressure plunger type limit switch being provided on the hydraulic power chamber. The second direct-pressure plunger type limit switch is fixed by a mounting bracket, and the plunger of the second direct-pressure plunger type limit switch is opposite to the frame area of ​​the hydraulic power unit.

[0013] More preferably, the hydraulic power chamber is also provided with a slide rail, the hydraulic power unit is installed on the slide rail, and the outermost slide rail connection of the hydraulic power unit is also provided with a trapezoidal top seat, the inclined surface of the trapezoidal top seat is opposite to the second direct pressure plunger type limit switch.

[0014] More preferably, it also includes a lifting cylinder, wherein the first direct-pressure plunger type limit switch and the second direct-pressure plunger type limit switch are connected in series to the control circuit of the lifting cylinder.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0016] The environment inside the compression chamber of a garbage compactor is harsh, damp, and filled with corrosive gases, which easily leads to corrosion and wear damage at the connection between the compression chamber and the telescopic device. Therefore, frequent maintenance is required. This application addresses this issue by providing a grease nipple, grease passage, and grease groove to the pin. The grease nipple allows maintenance personnel to directly add grease to the grease passage inside the pin, and the grease then flows out through the grease groove on the pin surface, ensuring that the hinge lug and the inner hole of the mounting base connected to the pin are also coated with grease, thus improving the convenience of maintenance.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] Example

[0029] Please see Figures 1 to 8 This embodiment provides a waste compression box that is easy to maintain, including a storage box 1, a hopper 3 and a tipping bucket 2. The tipping bucket 2 is provided with a tipping arm 5, a lifting cylinder 4 and a connecting rod 6 on both sides. The storage box 1 is fixed to the hopper 3. The tipping bucket 2 is connected to the hopper 3 by a hinge. The tipping arm 5 is rotatably connected to the outer wall of the hopper 3 and the outer wall of the tipping bucket 2 respectively. The tipping arm 5 is bent. One end of the lifting cylinder 4 is rotatably connected to the hopper 3, and the other end is rotatably connected to the bend in the middle of the tipping arm 5. One end of the connecting rod 6 is connected to the tipping bucket 2, and the other end is connected to the connection between the tipping arm 5 and the tipping bucket 2.

[0030] like Figure 1 and Figure 3 As shown, this embodiment also includes a compression chamber 9, which is located directly below the hopper 3. The compression end of the compression chamber 9 is equipped with a pusher 15. The operator pours the garbage into the tipping bucket 2, and then starts the lifting cylinders 4 on both sides. The tipping bucket 2 pours the garbage into the hopper 3 through a mechanism composed of tilting arms 5 and connecting rods 6 on both sides. The compression chamber 9 pushes forward, driving the pusher 15 to push the garbage into the storage box 1 and compress it.

[0031] like Figure 3 and Figure 5 As shown, the compression chamber 9 includes a telescopic device with hinges 10 at both ends. A mounting base 11 corresponding to the hinges 10 is provided inside the compression chamber 9. The hinges 10 are engaged in the mounting base 11 and connected by a pin 17. An oil passage 172 is provided inside the pin 17, and an oil groove 173 is provided on the surface of the pin 17, communicating with the oil passage 172. An oil nozzle 171 is provided at the top of the pin 17, communicating with the oil passage 172. Maintenance personnel add grease to the oil passage 172 inside the pin 17 through the oil nozzle 171. The grease flows from the oil passage 172 into the oil groove 173, thus coating the hinges 10 and the inner hole of the mounting base 11, which are connected to the pin 17 and in contact with the oil groove 173, with grease, improving maintenance convenience. In this embodiment, the oil groove 173 is preferably a spiral oil groove, which surrounds the outer circumference of the pin 17. This design reduces the number of oil grooves 173 required and decreases the machining difficulty of the pin 17. Simultaneously, it allows the pin 17 to quickly fill the gaps between the hinge lug 10, mounting base 11, and pin 17 during rotation, reducing wear and corrosion. Furthermore, since the pin 17 is a vulnerable component requiring frequent replacement, the oil nozzle 171 of the pin 17 in this embodiment is also provided with a threaded hole 174 with a diameter larger than the oil nozzle 171. This allows the pin 17 to be pulled out using a pin puller engaged with the threaded hole 174 during disassembly, facilitating its replacement.

[0032] In this embodiment, an extension tube 18 is connected to the grease fitting 171, extending beyond the compression chamber 9. When adding grease, maintenance personnel do not need to enter the cramped compression chamber 9; they can simply add grease through the extension tube 18 from the outside. This greatly simplifies the maintenance work and increases the frequency of maintenance.

[0033] Furthermore, in this embodiment, the outer surface of the compression chamber 9 is provided with an inspection port 16 near each pin 17. Each inspection port 16 includes a cover, which is fixed to the inspection port 16 with screws. The cover has an opening and closing filling hole, from which the extension tube 18 extends. Because the connection points of the pins 17 are prone to wear and corrosion, providing inspection ports 16 near the pins 17 facilitates direct external replacement and repair of damaged components. In particular, repairing the pins 17 near the pusher 15 is very inconvenient. By placing the inspection port 16 on the top plate of the compression chamber 9, maintenance personnel can extend the compression chamber 9, enter the hopper 3, and open the inspection port 16 to repair the pins 17 below. The hopper 3 has a large space, and the inspection port 16 is close to the pins 17, further facilitating maintenance and repair work.

[0034] More preferably, the compression chamber 9 is a segmented telescopic type, and a series of protective plates are provided above the compression chamber 9, namely a first protective plate 14 and a second protective plate 13. When the compression chamber 9 retracts, the first protective plate 14, the second protective plate 13, and the top plate of the compression chamber 9 overlap and stack. When the compression chamber 9 extends, the second protective plate 13 and the top plate of the compression chamber 9 slide out from under the first protective plate 14 in sequence. A support frame 19 is provided inside the compression chamber 9. The support frame 19 is fixed to the smallest vertical section of the compression chamber 9, and the width of the support frame 19 is smaller than the width of the smallest vertical section of the compression chamber 9. The extension tube 18 is fixed to the upper end of the support frame 19 in the retraction direction. When the compression chamber 9 is retracted to its smallest size, the extension tube 18 on the support frame 19 is close to the inspection door 8, which further facilitates the addition of grease to the pin 17 located at the innermost part of the compression chamber 9.

[0035] Furthermore, the side wall of the compression chamber 9 in the contraction direction is also provided with an openable and closable inspection door 8. The telescopic device consists of two intersecting hydraulic telescopic cylinders 12, one end of which is fixed to the side wall of the inspection door 8 on one side of the compression chamber 9. The intersecting hydraulic telescopic cylinders 12 can make the compression chamber 9 contract to its smallest volume as much as possible, thereby compressing more waste at once, improving work efficiency and stability during the compression process.

[0036] Preferably, the inspection door 8 is further provided with a first direct-pressure plunger type limit switch 81 at the door frame, which is fixed to the door frame by a mounting bracket 82. This embodiment also includes a hydraulic power chamber and a hydraulic power unit 7. The hydraulic power unit 7 is used to control the hydraulic structure inside the entire waste compression box. The hydraulic power unit 7 is slidably connected inside the hydraulic power chamber. A second direct-pressure plunger type limit switch 73 is provided on the hydraulic power chamber, which is fixed by a mounting bracket 82. The pressure column of the second direct-pressure plunger type limit switch 73 is opposite to the edge area of ​​the hydraulic power unit 7. When it is necessary to inspect the internal components of the compression chamber 9, the inspection door 8 is opened, and the pressure column of the first direct-pressure plunger type limit switch 81 pops out, disconnecting the control circuit of the lifting cylinder 4. When the inspection is completed and the inspection door 8 is closed, the door panel will press down the pressure column of the first direct-pressure plunger type limit switch 81, thereby connecting the control circuit of the lifting cylinder 4, at which point the tipping bucket 2 can be started. When the hydraulic power unit 7 is removed from the hydraulic power compartment for maintenance, the plunger of the second direct-pressure plunger-type limit switch 73 pops out, thus disconnecting the control circuit of the lifting cylinder 4. After maintenance is completed and the hydraulic power unit 7 is pushed back into the hydraulic power compartment, the frame of the hydraulic power unit 7 will press down the plunger of the second direct-pressure plunger-type limit switch 73, thus connecting the control circuit of the lifting cylinder 4. In this embodiment, the first direct-pressure plunger-type limit switch 81 and the second direct-pressure plunger-type limit switch 73 are connected in series to the control circuit of the lifting cylinder 4. Regardless of whether either direct-pressure plunger-type limit switch is in the open state, the lifting cylinder 4 cannot be activated to tilt, thus avoiding the danger caused by the tilting arm 5 colliding with the hydraulic power unit or the tipping bucket 2 colliding with the maintenance door 8.

[0037] More preferably, the hydraulic power chamber is further provided with a slide rail 72, and the hydraulic power unit 7 is mounted on the slide rail 72. A trapezoidal top seat 71 is also provided at the connection point of the outermost slide rail 72 of the hydraulic power unit 7. The inclined surface of the trapezoidal top seat 71 is opposite to the second direct-pressure plunger-type limit switch 73. The slide rail 72 makes the hydraulic power unit 7 more stable after it is pulled out. When the hydraulic power unit 7 is pushed back into the hydraulic power chamber, the trapezoidal top seat 71 can provide a buffer for the pressure column, preventing damage to components caused by the rapid pushback of the hydraulic power unit 7 impacting the pressure column.
