[0002] Compactor garbage trucks are a common and widely used type of garbage collection vehicle in urban sanitation systems. Due to their advantages such as garbage compression function, large loading capacity, good sealing, and high degree of automation, they are widely used in garbage collection and transfer in residential areas, streets, commercial areas, industrial parks and other places.

[0003] The compaction mechanism is one of the core working components of a compactor garbage truck. Its main function is to use a hydraulic system to drive scrapers to push garbage from the filling port into the garbage container, and then compress and compact it inside the container to improve loading and transportation efficiency.

The sensors are located on the sliding plate, and the sensing plate is located on the scraper cylinder. There is a risk that the sensors may be damaged by garbage or that garbage may get stuck between the sensing plate and the sensors, causing damage to the sensors. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] refer to Figures 1 to 3 The existing compaction mechanism includes a sliding plate 100, a sliding plate cylinder 200, a scraper 300, and a scraper cylinder 400. The sliding plate cylinder 200 drives the sliding plate 100 to slide on the garbage bin, and the scraper cylinder 400 drives the scraper 300 to rotate relative to the sliding plate 100, thereby switching the scraper 300 between an open position and a closed position. A sensor 500 is mounted on the sliding plate 100, and both the upper sensor plate 610 and the lower sensor plate 620 are mounted on the scraper cylinder 400.

[0027] The compaction cycle mainly consists of: scraper 300 opening – slide plate 100 descending – scraper 300 closing – slide plate 100 ascending. When scraper cylinder 400 extends, lower sensing plate 620 moves downward with the cylinder of scraper cylinder 400 to sensor 500. When sensor 500 senses lower sensing plate 620, it can determine that scraper 300 has closed and the next action can be executed. When scraper cylinder 400 retracts, upper sensing plate 610 moves upward with the cylinder to sensor 500. When sensor 500 senses upper sensing plate 610, it can determine that scraper 300 has opened and the next action can be executed.

[0028] However, currently, when loading waste, there is a possibility that the waste may fall onto the slide plate 100. Since the sensor 500 is located on the outside of the slide plate 100 and is exposed, there is a risk that the scraper 300 sensor may be damaged by the waste. Moreover, since the sensor plate 600 moves with the cylinder of the scraper cylinder 400, when the sensor plate 600 gets stuck with waste, the extension and retraction of the scraper cylinder 400 may cause the stuck waste to collide with the sensor 500, resulting in the sensor 500 being damaged.

[0029] Therefore, the inventors of this application have proposed an embodiment of a compaction mechanism and a compacted garbage truck to improve the above-mentioned defects.

[0030] A compactor garbage truck includes a chassis, a garbage bin located on the chassis, and a compaction mechanism located in the garbage bin.

[0031] The trash can is mainly used to store trash, while the compaction mechanism is used to compress the trash inside the trash can so that the trash can can hold more trash.

[0032] refer to Figures 4 to 6 The compaction mechanism includes a slide plate 100, a slide plate cylinder 200, a scraper 300, a scraper cylinder 400, and a sensing component; The scraper 300 is hinged to the slide plate 100; The two ends of the scraper cylinder 400 are respectively hinged to the scraper 300 and the slide plate 100. The scraper cylinder 400 can drive the scraper 300 to rotate relative to the slide plate 100 between the scraping position and the opening position. The sensing assembly includes a sensing box 700, a sensor 500, and a sensing plate 600. The sensing box 700 is fixed on the slide plate 100. One of the slide plate 100 and the scraper 300 is connected to the sensor 500, and the other is connected to the sensing plate 600. At least a portion of the sensing plate 600 and the sensor 500 are always located inside the sensing box 700. During the process of the scraper cylinder 400 driving the scraper 300 to rotate relative to the slide plate 100, when the sensor 500 senses the sensing plate 600, the scraper cylinder 400 stops driving the scraper 300.

[0033] In this way, the sensor 500 is housed in the sensor box 700 fixed on the slide plate 100. When garbage is being fed, it will only hit the sensor box 700 and will not damage the sensor 500. In addition, since at least a part of the sensor plate 600 is always located inside the sensor box 700, and the sensor 500 or the sensor plate 600 is connected to the scraper 300, when the scraper cylinder 400 drives the scraper 300 to rotate relative to the slide plate 100, the sensor 500 or the sensor plate 600 will also make a circular motion around the hinge center of the slide plate 100 and the scraper 300. Therefore, it is not easy for garbage to get stuck and damage the sensor 500, thus ensuring that the sensor 500 is protected from abnormal damage and extending its service life.

[0034] The following describes some embodiments of this application in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] First Embodiment refer to Figure 7 and Figure 8 At least one side wall of the sensor box 700 is constructed to be inclined at an acute angle relative to the slide plate 100, which facilitates the rapid rolling of trash after it falls onto the sensor box 700.

[0036] In detail, the sensor box 700 includes a base box 710 and a cover plate 720; the base box 710 is connected to the slide plate 100, and the top wall of the base box 710 away from the slide plate 100 has an opening 711; the cover plate 720 is detachably connected to the base box 710 and covers the opening 711.

[0037] In this way, when installing the sensor plate 600 and the sensor 500, the cover plate 720 can be removed from the base box 710 to open the opening 711 for easy installation. After installation, the cover plate 720 can be installed back onto the base box 710.

[0038] The bottom box 710 and the cover plate 720 can be detachably connected by screws. Of course, in some embodiments, the bottom box 710 and the cover plate 720 can also be connected by snap-fit, etc.

[0039] The bottom box 710 is roughly trapezoidal in shape, with its side wall away from the scraper 300 inclined at an acute angle relative to the slide plate 100. This side wall serves as an inclined wall 713 to ensure sufficient impact resistance while facilitating the rapid rolling of waste off the inclined side wall.

[0040] Of course, in some embodiments, the base box 710 may also be constructed in which each side wall is inclined at an acute angle to the slide plate 100.

[0041] Continue to refer to Figure 8 The sensor box 700 also includes a sealing ring 730, which surrounds the outer periphery of the opening 711. The bottom box 710 and the cover plate 720 together compress the sealing ring 730, thus preventing rainwater from entering the sensor box 700 and protecting the sensor 500. The sealing ring 730 can be made of flexible and elastic materials such as rubber.

[0042] In this embodiment, the sensor 500 is fixed to the slide plate 100; an opening 712 is provided on the side wall of the bottom box 710 near the scraper 300; the sensing plate 600 is arc-shaped, with one end fixed to the scraper 300 and the other end extending into the sensing box 700 through the opening 712; the hinge center of the slide plate 100 and the scraper 300 coincides with the center of the sensing plate 600. The sensor plate 600 can rotate in a circular motion relative to the hinge center of the slide plate 100 and the scraper 300 as the scraper 300 rotates.

[0043] In this way, the sensor plate 600 is made into an arc shape with its center coinciding with the hinge center of the slide plate 100 and the scraper 300. This ensures that when the scraper 300 is driven to rotate by the scraper cylinder 400, the sensor plate 600 has no radial displacement and only performs circular motion. This allows the opening 712 on the sensor box 700 to be made as small as possible, preventing garbage from entering the sensor box 700 through the gap between the sensor plate 600 and the opening 712.

[0044] Continue to refer to Figures 1 to 3In the existing technology, a single sensor 500 is used to determine the opening and closing position of the scraper 300. Before the compaction cycle, the scraper cylinder 400 must first drive the scraper 300 to open to determine the first sensing position as the opening position, which affects the compaction cycle efficiency.

[0045] In this embodiment, reference Figures 8 to 10 There are two sensors 500, namely a first sensor 510 and a second sensor 520. The first sensor 510 and the second sensor 520 are arranged in an arc with the hinge center of the slide plate 100 and the scraper 300 as the center. In the circumferential direction with the hinge center of the slide plate 100 and the scraper 300 as the center, the first sensor 510 is farther away from the scraper 300 than the second sensor 520. Therefore, in the direction of movement of the scraper 300, the first sensor 510 is closer to the slide plate 100 than the second sensor 520. During the process of the scraper cylinder 400 driving the scraper 300 to turn from the scraping position to the opening position relative to the slide plate 100, when both the first sensor 510 and the second sensor 520 sense the sensing plate 600, the scraper cylinder 400 stops driving the scraper 300, thereby stopping the scraper 300 in the opening position and opening it to the correct position.

[0046] During the process of the scraper cylinder 400 driving the scraper 300 to move from the open position to the scraping position relative to the slide plate 100, when neither the first sensor 510 nor the second sensor 520 detects the sensing plate 600, the scraper cylinder 400 stops driving the scraper 300, thereby stopping the scraper 300 in the scraping position and scraping in place.

[0047] By simultaneously sensing or not sensing the sensing plate 600 through the first sensor 510 and the second sensor 520, the opening and closing positions of the scraper 300 can be determined, improving the accuracy of the scraper 300's position determination. The compaction cycle can then be performed directly without the scraper 300 needing to open before the operation. Therefore, using dual sensors 500 can make the compaction cycle more efficient.

[0048] In the direction of the rotation axis of the scraper 300, that is, in the axial direction of the hinge axis between the scraper 300 and the slide plate 100, the first sensor 510 and the second sensor 520 are respectively located on both sides of the sensing plate 600. In this way, the first sensor 510 and the second sensor 520 have sufficient space for easy installation and debugging. Of course, in some embodiments, the first sensor 510 and the second sensor 520 can also be located on one side of the sensing plate 600, as long as the sensing box 700 leaves enough space.

[0049] Continue to refer to Figure 1In the existing technology, the sensor 500 is located in the gap between the scraper cylinder 400 and the slide cylinder 200. The sensor 500 has a hinge pin on the left and right sides, which makes the installation, debugging and replacement of the sensor extremely inconvenient.

[0050] In this embodiment, we continue to refer to... Figure 4 Two scraper cylinders 400 are arranged side by side, and the sensing component is located between the two scraper cylinders 400. This allows the transverse dimension of the sensing box 700 to be designed to be larger, thereby increasing its internal space and facilitating the installation and debugging of the sensor 500.

[0051] In summary, this embodiment discloses a compaction mechanism and a compressed garbage truck, which have at least the following advantages compared to the prior art: 1. The sensor 500 is protected by a flat sensor box, which can effectively prevent it from being damaged by garbage. 2. The flat sensor box 700 has a larger internal space, which facilitates the installation and debugging of sensors; 3. The sensor plate 600 adopts a rotating motion, and its head is always located inside the sensor 500 box, so that garbage is not easy to get stuck and damage the sensor 500. 4. Using dual sensors to identify a single sensing plate 600 can make the compaction cycle more efficient.

[0052] Second Embodiment This embodiment also uses dual sensors 500, namely a first sensor 510 and a second sensor 520. In the direction of movement of the scraper 300, the first sensor 510 is closer to the slide plate 100 than the second sensor 520. However, unlike the first embodiment, the logic for determining when the scraper 300 is open and closed is different.

[0053] Specifically, refer to Figure 11 and Figure 12 In this embodiment, during the process of the scraper cylinder 400 driving the scraper 300 to turn from the scraping position to the opening position relative to the slide plate 100, when the first sensor 510 senses the sensing plate 600, the scraper cylinder 400 stops driving the scraper 300, thereby stopping the scraper 300 in the opening position and opening it in place.

[0054] During the process of the scraper cylinder 400 driving the scraper 300 to move from the open position to the scraping position relative to the slide plate 100, when the second sensor 520 senses the sensing plate 600, the scraper cylinder 400 stops driving the scraper 300, thereby stopping the scraper 300 in the scraping position and scraping in place.

[0055] In this way, by using a sensor 500 at different locations to detect and determine the opening or closing state of the scraper 300, the compaction efficiency can also be improved.

[0056] More specifically, in the direction of the rotation axis of the scraper 300, the first sensor 510 and the second sensor 520 are located on both sides of the sensing plate 600; the sensing plate 600 is provided with a sensing protrusion 630 at one end inside the sensing box 700, and the sensing protrusion 630 is located on the side of the sensing plate 600 close to the second sensor 520. During the process of the scraper cylinder 400 driving the scraper 300 to turn from the scraping position to the opening position relative to the slide plate 100, when the first sensor 510 senses the sensing protrusion 630, the scraper cylinder 400 stops driving the scraper 300, and the scraper 300 opens to the position. During the process of the scraper cylinder 400 driving the scraper 300 to move from the open position to the scraping position relative to the slide plate 100, when the second sensor 520 senses the sensing protrusion 630, the scraper cylinder 400 stops driving the scraper 300, and the scraper 300 scrapes into place.

[0057] In this way, since the sensing protrusion 630 is located on the side of the sensing plate 600 close to the second sensor 520, when the sensing protrusion 630 and the first sensor 510 are exactly coaxial, the distance between the sensing plate 600 and the second sensor 520 is insufficient to trigger the second sensor 520. Therefore, the recognition of the scraper 300 opening into position can be realized. When the sensing protrusion 630 and the second sensor 520 are exactly aligned, the second sensor 520 is not blocked by the sensing plate 600. Therefore, the recognition of the scraper 300 closing into position can be realized.

[0058] Of course, in some embodiments, the first sensor 510 and the second sensor 520 may also be located on the same side of the sensing plate 600. In this way, when the sensing protrusion 630 is aligned with the first sensor 510, the first sensor 510 can identify the sensing protrusion 630 on the sensing plate 600.

[0059] It should be noted that in this embodiment, the sensing plate 600 can be an arc shape with its center coinciding with the rotation axis of the scraper 300, and the first sensor 510 and the second sensor 520 are also arc-shaped and spaced apart with the rotation axis of the scraper 300 as the central axis.

[0060] In addition, the sensing plate 600 can also be other shapes, as long as it can be sensed by either the first sensor 510 or the second sensor 520 as the scraper 300 moves.

[0061] Third Embodiment Unlike the first embodiment, this embodiment uses a single sensor 500 to sense the dual sensor plate 600.

[0062] Specifically, refer to Figure 13The sensing component also includes an arc plate 800, one end of which is connected to a scraper 300. The center of the arc plate 800 coincides with the hinge center of the slide plate 100 and the scraper 300. The arc plate 800 passes through an opening 712 provided on the bottom box 710 of the sensing box 700 to extend into the sensing box 700. The sensor 500 is fixed to the other end of the arc plate 800. There are two sensing plates 600, namely the first sensing plate 640 and the second sensing plate 650. The first sensing plate 640 and the second sensing plate 650 are arranged in an arc with the hinge center of the slide plate 100 and the scraper 300 as the center. In the circumferential direction, the first sensing plate 640 is farther away from the scraper 300 than the second sensing plate 650. During the process of the scraper cylinder 400 driving the scraper 300 to turn from the scraping position to the opening position relative to the slide plate 100, when the sensor 500 senses the first sensing plate 640, the scraper cylinder 400 stops driving the scraper 300. During the process of the scraper cylinder 400 driving the scraper 300 to move from the open position to the scraping position relative to the slide plate 100, when the sensor 500 senses the second sensing plate 650, the scraper cylinder 400 stops driving the scraper 300.

[0063] In this way, by using a single sensor 500 to sense the first sensor plate 640 and the second sensor plate 650 respectively, the opening and closing positions of the scraper 300 can be determined.

[0064] Finally, it should be noted that in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0065] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
