Description

Technical Field

[0001] This utility model belongs to the field of compression technology, specifically, it relates to a box-type auxiliary compression device for garbage. Background Technology

[0002] With the acceleration of urbanization, the amount of various types of waste is constantly increasing. In order to reduce environmental pollution, save land resources, improve people's values, and realize the reuse of resources, waste recycling and disposal has become an important means of maintaining environmental sanitation.

[0003] Currently, in the process of garbage recycling, in order to improve the utilization rate of garbage bins, the garbage inside the bins is usually compressed by a compression device. However, in actual operation, since the garbage bags filled with garbage inevitably contain sewage or other fluid-like dirt, sewage or fluid-like dirt will inevitably overflow into the compression device during the garbage compression process, causing pollution to the compression device and seriously affecting the service life of the compression device. Utility Model Content

[0004] In order to solve the problems existing in the prior art, this utility model aims to provide a box-type auxiliary garbage compression device. By cooperating with the garbage collection box, it can compress the garbage in the garbage bin of the garbage collection box while effectively preventing sewage or fluid waste from overflowing into it, thus improving its service life.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A container-type auxiliary garbage compression device includes an inner container and an outer container sleeved on the outside of the inner container. A lifting mechanism is provided on the bottom surface of the inner container, which can drive the outer container to move up and down along the outer side of the inner container. A reverse clamping device is provided on one of the pair of inner side walls of the inner container. A positioning groove adapted to the reverse clamping device is formed on the inner surface of the outer container. The position of the outer container after it has moved down along the outer side of the inner container is limited by the cooperation of the reverse clamping device and the positioning groove.

[0007] Furthermore, an installation component is provided at the upper end of the inner casing.

[0008] Furthermore, a clearance groove is provided on the bottom surface of the outer casing.

[0009] Furthermore, the lifting mechanism includes a mounting base, on which a drive motor is mounted. A first gear is sleeved on the output shaft of the drive motor. The first gear meshes with a second gear. A lead screw passes through the gear hole of the second gear. The lead screw is threadedly connected to the gear hole of the second gear, and the lead screw passes through the top surface of the mounting base.

[0010] Furthermore, both the first gear and the second gear are spur gears.

[0011] Furthermore, the reverse fastener includes a latch, a magnet, and a protective box; the latch is slidably disposed inside the protective box, the magnet is fixed inside the protective box, and the latch can be attracted to the protective box by the magnet; at least two sets of springs are disposed between the latch and the protective box, and the springs tend to drive the latch to move out of the protective box when no external force is applied.

[0012] Furthermore, a guide shaft corresponding to each spring is provided between the latch and the protective box. One end of the guide shaft is fixedly connected to the latch, and the other end of the guide shaft passes through the protective box and can slide within the protective box.

[0013] Furthermore, a limiting groove is formed on the bottom surface of the latch, and a protrusion adapted to the limiting groove is provided in the positioning groove.

[0014] The beneficial effects of this utility model are as follows: Firstly, by setting inner and outer boxes and cooperating with a lifting mechanism, the outer box moves up and down along the outer surface of the inner box. This allows it to compress the garbage inside the garbage bin while effectively preventing sewage or fluid waste from overflowing into it, thus extending its service life. Secondly, by setting a reverse clamp on the inner box and opening a positioning groove on the outer box, the maximum downward displacement of the outer box is limited. Furthermore, by setting a limiting groove in the reverse clamp and a protrusion in the positioning groove that matches the limiting groove, a male-female interlocking mechanism is achieved between the reverse clamp and the limiting groove, thus preventing the reverse clamp from failing when the outer box is subjected to pressure.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0027] See Figure 1-2As shown, a container-type auxiliary garbage compression device includes an inner container 1 and an outer container 2 sleeved on the outside of the inner container 1. A lifting mechanism 3 is provided on the inner bottom surface of the inner container 1, which can drive the outer container 2 to move up and down along the outer side surface of the inner container 1. A reverse fastener 4 is provided on one pair of inner side walls of the inner container 1. A positioning groove 201 adapted to the reverse fastener 4 is opened on the inner surface of the outer container 2. The position of the outer container 2 after it moves down along the outer side surface of the inner container 1 is limited by the cooperation of the reverse fastener 4 and the positioning groove 201.

[0028] Further details can be found by referring to [link / reference]. Figure 1-2 As shown, in this embodiment, the upper end of the inner box 1 is provided with two pairs of mounting parts 5, which are respectively disposed at the top of a pair of side walls of the inner box 1. Of course, it is not limited to two pairs, but can be more. In use, the mounting parts 5 facilitate the installation of this device. The bottom surface of the outer box 2 is provided with multiple sets of clearance grooves 202, which are evenly distributed on the bottom surface of the outer box 2.

[0029] Further, see Figure 4 As shown, in this embodiment, the lifting mechanism 3 includes a mounting base 301. A vertically downward drive motor 302 is mounted on the mounting base 301. The output shaft of the drive motor 302 passes through the top surface of the mounting base 301, and a first gear 303 is sleeved on the output shaft of the drive motor 302. The first gear 303 meshes with a second gear 304. A lead screw 305 passes through the gear hole of the second gear 304. The lead screw 305 is threadedly connected to the gear hole of the second gear 304, and the lead screw 305 passes through the top surface of the mounting base 301 and can rotate within the mounting base 301. For installation, see [reference needed]. Figure 2 As shown, the mounting base 301 is locked to the inner bottom surface of the inner housing 1 by locking screws, and the lower end of the lead screw 305 is fixedly connected to the inner bottom surface of the outer housing 2. During operation, the drive motor 302 drives the second gear 304 to rotate through the first gear 303, thereby driving the lead screw 305 to move up and down, and then driving the outer housing 2 to move up and down along the outer side surface of the inner housing 1. In this embodiment, both the first gear 303 and the second gear 304 are spur gears.

[0030] Further, see Figure 5As shown, in this embodiment, the reverse fastener 4 includes a latch 401, a magnet 402, and a protective box 403. The latch 401 is slidably disposed inside the protective box 403, and the magnet 402 is fixed inside the protective box 403. The magnet 402 can attract the latch 401 into the protective box 403. Two sets of springs 404 are disposed between the latch 401 and the protective box 403. Without the action of external force, the springs 404 have a tendency to drive the latch 401 to move out of the protective box 403. In this embodiment, one end of the spring 404 is recessed into the latch 401 and abuts against the latch 401, while the other end of the spring 404 abuts against the protective box 403. Of course, the number of spring groups and the connection method of the springs 404 described above are only one implementation method and are not intended to limit the scope of this application. In actual installation, the number of spring groups can be increased, and the connection method of the springs 404 can also be fixed, such as welding. For installation, see [reference needed]. Figure 2 As shown, the reverse fastener 4 is fixed to the inner surface of the inner housing 1 by the protective box 403. At this time, the inner housing 1 opposite to the latch 401 has a through hole through which the latch 401 can pass. During operation, when the magnet 402 is closed, the latch 401 can slide out of the protective box 403 under the action of the spring 404, and after passing through the through hole, the front end of the latch 401 protrudes from the inner housing 1. When the magnet 402 is activated, the latch 401... 1. The device retracts and returns to its original position under the attraction of the magnet 402. In this embodiment, in order to prevent the latch 401 from shifting during movement, a guide shaft 405 corresponding to the spring 404 is provided between the latch 401 and the protective box 403. One end of the guide shaft 405 is fixedly connected to the latch 401, and the other end of the guide shaft 405 passes through the protective box 403 and can slide in the protective box 403. The spring 404 is sleeved on the corresponding guide shaft 405.

[0031] Further, see Figure 3 and Figure 5 As shown, in this embodiment, the bottom surface of the latch 401 is provided with a limiting groove 4011, and the positioning groove 201 is provided with a protrusion 2011 that matches the limiting groove 4011. During operation, when the front end of the latch 401 extends from the middle of the inner box 1 and enters the positioning groove 201, the limiting groove 4011 engages with the protrusion 2011, achieving a male-female snap-fit, thereby preventing the outer box 2 from being squeezed by force, causing the latch 401 to slide into the protective box 403, which would result in the failure of the limiting function on the outer box 2.

[0032] The working principle of this utility model is as follows:

[0033] This device needs to be installed in the garbage collection bin. See below. Figure 6-7 As shown in the figure (label A represents this device; label B represents the trash can; label C represents the trash can lifting mechanism), at this time, this device and the trash can lifting mechanism are connected to the control system; when it is necessary to compress the trash in the trash can, the drive motor 302 is started and controlled to reverse. The drive motor 302 drives the second gear 304 to rotate through the first gear 303. At this time, the rotating second gear 304 drives the lead screw 305 to move downward, thereby causing the outer casing 2 to move downward. The displacement height is controlled by the control system to control the drive motor 302; when the outer casing 2 moves downward to the set position, the drive motor 302 is turned off, and at the same time, the magnetic... The force generator 402 is also closed. At this time, the latch 401 slides out of the protective box 403 under the action of the spring 404, passes through the through hole, and the front end of the latch 401 extends into the positioning groove 201. Then, the drive motor 302 is started and controlled to rotate forward one revolution, driving the outer box 2 to move upward a certain distance, so that the protrusion 2011 enters the limiting groove 4011, realizing the male and female snap engagement. At this time, the bottom of the outer box 2 is close to the garbage can opening. Then the garbage can lifting mechanism lifts the garbage can upward, realizing the outer box 2 compressing the garbage in the garbage can. It should be noted that in this embodiment, during operation, this device starts 3 seconds before the garbage can lifting mechanism.

[0034] After compression, the garbage bin lifting mechanism retracts, causing the garbage bin to descend. Then, the drive motor 302 is activated, and the drive motor 302 is reversed one revolution, driving the outer casing 2 to move downwards by a certain distance, causing the protrusion 2011 to disengage from the limiting groove 4011. Then, the magnet 402 is activated, at which point the latch 401 is attracted by the magnet 402 and exits from the positioning groove 201 to reset. Then, the drive motor 302 is controlled to rotate forward, and stops after driving the outer casing 2 to move upwards and retract to reset. At this time, the bottom of the outer casing 2 is away from the garbage bin opening, making it easier for the garbage bin to continue collecting garbage.

[0035] It should be noted that in this embodiment, the drive motor 302 drives the outer housing 2 to move downward in reverse and drives the outer housing 2 to move upward in forward rotation; however, it is not limited to the above-mentioned arrangement, and in actual settings, it can also be arranged in the opposite direction.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
