Description

Technical Field

[0001] The utility model relates to the technical field of garbage trucks, in particular to a shovel device for a compression type garbage truck. Background Art

[0002] The compression garbage truck is composed of a sealed garbage compartment, a hydraulic system, and an operating system. The whole vehicle is fully sealed, and it compresses and dumps itself. The sewage in the compression process all enters the sewage compartment, which thoroughly solves the problem of secondary pollution in the process of garbage transportation and avoids inconvenience to people. The compression garbage truck is composed of a hanging bucket flipping mechanism, a garbage bucket flipping mechanism, and a shovel mechanism.

[0003] The shovel mechanism uses a multi-stage cylinder to push the push plate to discharge the garbage, but there is a gap between the bottom of the existing push plate and the bottom plate of the garbage truck compartment. The purpose is to prevent the bottom plate from deforming and protruding after long-term use, which leads to contact with the push plate and cracking of the bottom plate. Although the cracking of the bottom plate can be avoided by retaining the gap, the residual stains of the garbage will remain in the car when the garbage is pushed, resulting in the problem of unclean cleaning of the stains. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a shovel device for a compression type garbage truck, which solves the problem that when pushing garbage, the residual stains of the garbage will remain in the vehicle, resulting in the stains not being cleaned up thoroughly.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: a shovel device for a compression garbage truck, comprising a push plate 1, a support frame 2 is arranged on the back of the push plate 1, a multi-stage cylinder 3 is rotatably connected between the back of the push plate 1 and the support frame 2 through a rotating member, a mounting groove 4 is opened at the bottom of the push plate 1, and a cleaning mechanism 5 is arranged between the inner cavity of the mounting groove 4 and the back.

[0026] See also Figure 5-6The cleaning mechanism 5 includes a connecting plate 51 and a sliding plate 59. The sliding plate 59 and the connecting plate 51 are slidably sleeved in the inner cavity of the mounting groove 4. A plurality of limiting grooves 58 are provided at the bottom of the connecting plate 51. A hard plate 56 is fixedly installed in the inner cavity of the plurality of limiting grooves 58 by screws. The bottoms of the plurality of hard plates 56 are respectively fixedly connected with a scraper 53, a wiper curtain 54 and a brush 55. The top of the connecting plate 51 is symmetrically provided with a scraper 53. The middle of the top of the sliding plate 59 is rotatably connected with a small oil cylinder 57 through a rotating member. The output end of the small oil cylinder 57 passes through the inner wall of the mounting groove 4, and the end head is movably arranged on the inner wall of the mounting groove 4. On the back of the push plate 1, the scraper 53 is in an arc-shaped triangle. When it comes into contact with the protruding bottom plate of the garbage truck compartment, the protruding bottom plate will automatically extend and retract the hard plate 56 with the arc degree of the triangle. There is a gap between the connecting plate 51 and the sliding plate 59, so that the elastic component 52 can realize the extension and retraction space. A groove for the installation of the small oil cylinder 57 is fixed on the back of the push plate 1, and a hole larger than the extension end of the small oil cylinder 57 is also provided in the groove. The larger hole can make the small oil cylinder 57 move, and its output end can tilt itself when driving the sliding plate 59 to move.

[0027] The extended end of the small oil cylinder 57 passes through the hole, and the end of the small oil cylinder 57 is rotatably installed in the groove, and the small oil cylinder 57 is installed obliquely as a whole. In addition, the scraper 53 is made of hard rubber material, and the wiper curtain 54 is made of soft rubber material.

[0028] See also Figure 7 , and also includes an elastic component 52, the elastic component 52 includes a sleeve 521, the inner cavity of the sleeve 521 is slidably sleeved with a sliding column 523, a spring 522 is fixedly connected between the inner cavity of the sleeve 521 and one end of the sliding column 523, the sliding column 523 is fixedly connected to the top of the connecting plate 51, and the sleeve 521 is fixedly connected to the bottom of the sliding plate 59. The sleeve 521 and the sliding column 523 can be extended and retracted by the spring 522, thereby driving the effect of automatically tightening the connecting plate 51.

[0029] Furthermore, the length of the wiper curtain 54 and the brush 55 is greater than that of the scraper 53, and the hard plate 56 is consistent with the inner cavity of the installation groove 4 and is flush with the connecting plate 51 to prevent protrusions from rubbing and colliding with the car body.

[0030] When in use, the two sides of the push plate 1 are provided with slide grooves for the slide rails to slide, so the slide grooves are slidably arranged on the slide rails, and then the small oil cylinder 57 is rotated and installed in the garbage truck. After the installation is completed,

[0031] Start the small oil cylinder 57, so that it rotates and drives the sliding plate 59 to move downward, so that the connecting plate 51 also moves downward, and through the elastic force of the spring 522, the sliding column 523 will slide in the sleeve 521, thereby driving the connecting plate 51 to move downward in the inner cavity of the mounting groove 4, so that the scraper 53, the wiper curtain 54 and the brush 55 are in contact with the floor of the car. At this time, since the wiper curtain 54 and the brush 55 are longer than the scraper 53, they will be squeezed and contacted on the floor.

[0032] Then the multi-stage cylinder 3 is started to push the push plate 1 to slide on the slide rail, thereby pushing the garbage to move, and the scraper 53, the wiper curtain 54 and the brush 55 will slide with the bottom plate, and the scraper 53, the wiper curtain 54 and the brush 55 will be used to scrape the stains remaining on the bottom plate of the car. In addition, when encountering a protruding bottom plate, it will first contact the scraper 53, and through the triangular curvature of the scraper 53, the protruding part of the bottom plate will squeeze the scraper 53 along the curvature. When the squeezing force is greater than the elastic force of the spring 522, the sliding column 523 and the spring 522 will retract in the sleeve 521, thereby driving the connecting plate 51 to retract as a whole in the inner cavity of the mounting groove 4, so that the scraper 53 passes over the protruding part of the bottom plate, and the wiper curtain 54 and the brush 55 behind will squeeze the bottom plate to clean it, so that the remaining stains are discharged outside the car, thereby improving the cleaning ability.

[0033] In addition, after the first garbage push is completed, when resetting, the small oil cylinder 57 is started, so that the small oil cylinder 57 rotates to drive the sliding plate 59 to move upward, so that the elastic component 52 and the connecting plate 51 also move, so that the scraper 53, the wiper curtain 54 and the brush 55 leave the bottom plate, so that when resetting, they will not sweep back. When the resetting is completed, the small oil cylinder 57 is reset again, so that the scraper 53, the wiper curtain 54 and the brush 55 are in contact with the bottom plate.
