Abstract
Description
Technical Field
[0001] This utility model applies to the field of garbage truck technology and provides a rear-loading compression garbage truck sliding plate mechanism. Background Technology
[0002] Rear-loading compactor garbage trucks are a common type of sanitation vehicle used for collecting urban household waste. Their core structure consists of a garbage collection bin at the rear. The main function is to collect garbage through the rear hopper, then compress it using an internal compression mechanism before transferring it to the main garbage bin. This compression significantly increases the main bin's capacity. The compression mechanism is achieved by a reciprocating scraper plate inside the hopper, with a rotating scraper at the rear. During the scraper plate's movement, the rotating scraper compresses the garbage. The scraper compresses and scrapes the garbage into the main garbage bin. Usually, the scraper slide is directly driven by a hydraulic cylinder or a pneumatic cylinder. However, in this direct drive method, the scraper slide lacks support during its reciprocating movement. The reaction force of the garbage compression acts on the hydraulic cylinder extension rod and the actuation connection of the scraper slide. Over time, the actuation connection of the scraper slide and the hydraulic cylinder extension rod will deform. This will lead to problems such as the scraper slide swaying left and right and bumping during operation, affecting the stability of the scraper slide operation, and greatly reducing the service life of each component. Utility Model Content
[0003] Therefore, this utility model provides a rear-loading compression garbage truck sliding plate mechanism. The actuation connection position of the scraper sliding plate is reinforced by the actuation part reinforcement plate to reduce the probability of deformation. At the same time, the guide wheel mechanism, the side support ball of the reinforcement plate and the side support ball of the roller provide multi-directional support for the scraper sliding plate during movement, further ensuring the stability of the scraper sliding plate under long-term operation.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a rear-loading compression garbage truck sliding plate mechanism, including a collection hopper, a scraping sliding plate, and a sliding plate drive device. The scraping sliding plate is disposed inside the collection hopper. The scraping sliding plate includes a movable base plate, and drive side plates are respectively disposed on the left and right sides of the movable base plate. Actuating part reinforcing plates are respectively disposed at the front and rear ends of the drive side plates facing the collection hopper. A guide wheel mechanism is disposed on the actuating part reinforcing plate facing the collection hopper. The guide wheel mechanism includes a roller shaft and a supporting roller. The roller shaft is fixedly connected to the drive side plate. Roller guide grooves adapted to the supporting rollers are respectively disposed on the left and right sides inside the collection hopper. The sliding plate drive device is disposed on the side of the collection hopper and drivenly connected to the scraping sliding plate for driving the scraping sliding plate to reciprocate.
[0005] Furthermore, the reinforcing plate of the actuating part is also provided with reinforcing plate side support balls, which are rotatably disposed on the side of the actuating part reinforcing plate facing the hopper. Reinforcing plate ball support strips adapted to the reinforcing plate side support balls are respectively provided on the left and right sides of the hopper, and the reinforcing plate side support balls abut against the reinforcing plate ball support strips.
[0006] Furthermore, a roller side support ball is provided on the side of the roller shaft facing the hopper, and a roller ball support bar adapted to the roller side support ball is provided at the bottom of the roller guide groove, and the roller side support ball abuts against the roller ball support bar.
[0007] Furthermore, a bottom baffle is provided inside the hopper. The bottom baffle is located below the scraper slide plate. Several slide plate guide grooves are provided on the side of the bottom baffle facing the scraper slide plate. Several slide plate bottom guide strips are provided on the side of the scraper slide plate facing the bottom baffle, which are adapted to the several slide plate guide grooves one by one.
[0008] Furthermore, there are two sliding plate drive devices, which are respectively arranged on both sides of the hopper. The connection between the sliding plate drive device and the scraping sliding plate is located on the actuating part reinforcing plate.
[0009] Furthermore, the skateboard drive device is a linear drive cylinder or a linear drive hydraulic cylinder.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. In the present invention, by setting actuation reinforcement plates at the front and rear ends of the drive side plate of the scraper slide, the actuation connection position of the scraper slide (i.e. its main stress points, such as the connection position between the slide drive device and the scraper slide, the installation connection position of the scraper on the scraper slide, etc.) is set at the actuation reinforcement plate position. This can effectively reduce the probability of deformation of the scraper slide after long-term operation and improve the running stability of the scraper slide.
[0012] 2. The guide wheel mechanism provides bottom support for the scraper slide, while the side support balls of the reinforcing plate and the side support balls of the roller provide side support for the scraper slide, providing multi-directional support to further ensure the stability of the scraper slide during long-term operation. At the same time, the guide wheel mechanism, the side support balls of the reinforcing plate and the side support balls of the roller are rolled or rotated against the hopper, and the friction during their movement is small, so there will be no excessive energy loss.

[0020] 300. Skateboard drive unit. Detailed Implementation
[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0022] Example, see attached document Figure 1 This utility model provides a rear-loading compression garbage truck sliding plate mechanism, including a collection hopper 100, a scraping sliding plate 200, and sliding plate drive devices 300. There are two sliding plate drive devices 300, respectively located on both sides of the collection hopper 100 and both connected to the scraping sliding plate 200 for driving its reciprocating movement. For the sake of equipment versatility and ease of maintenance, the sliding plate drive devices 300 generally adopt common linear drive cylinders or linear drive hydraulic cylinders. The scraping sliding plate 200 is located inside the collection hopper 100, as shown in the attached diagram. Figure 2 Appendix Figure 3 As shown, the scraper slide 200 includes a movable base plate 210. Drive side plates 220 are respectively provided on the left and right sides of the movable base plate 210. Actuating part reinforcing plates 230 are respectively provided at the front and rear ends of the drive side plates 220 facing the hopper 100. The function of the actuating part reinforcing plates 230 is to specifically reinforce the ends of the drive side plates 220, which is cost-effective. A guide wheel mechanism 250 is provided on the actuating part reinforcing plate 230 facing the hopper 100, as shown in the attached figure. Figure 4As shown, the guide wheel mechanism 250 includes a roller shaft 251 and a support roller 252. The roller shaft 251 is fixedly connected to the drive side plate 220. Roller guide grooves 110, adapted to the support rollers 252, are respectively provided on the left and right sides of the hopper 100. During the reciprocating movement of the drive side plate 220, the support rollers 252 provide bottom support for the scraper slide 200 and also guide the movement direction of the scraper slide 200 to prevent deviation. Part of the actuating part reinforcing plate 230 is also provided with reinforcing plate side support balls 240. The reinforcing plate side support balls 240 are rotatably disposed on the side of the actuating part reinforcing plate 230 facing the hopper 100. For example, in this embodiment, the actuating part reinforcing plate 230 is located at the upper end of the drive side plate 220. The reason for the addition of the reinforcing plate side support ball 240 is that, in this embodiment, the connection between the slide drive device 300 and the scraper slide 200 is located on the actuating part reinforcing plate 230 at the upper end of the drive side plate 220. The force at this position is relatively large, so the reinforcing plate side support ball 240 is added to provide better side support for the scraper slide 200. The left and right sides of the collecting hopper 100 are respectively provided with reinforcing plate ball support strips 120 that are adapted to the reinforcing plate side support ball 240. The reinforcing plate side support ball 240 abuts against the reinforcing plate ball support strip 120. The purpose of the reinforcing plate ball support strip 120 is to avoid direct contact between the reinforcing plate side support ball 240 and the collecting hopper 100, which would cause wear on the housing of the collecting hopper 100.
[0023] To further enhance the side support of the scraper slide 200, as shown in the attached... Figure 4 As shown, a roller side support ball 253 is provided on the side of the roller shaft 251 facing the hopper 100. A roller ball support strip 130 adapted to the roller side support ball 253 is provided at the bottom of the roller guide groove 110. The roller side support ball 253 abuts against the roller ball support strip 130, which has the same function as the reinforcing plate side support ball 240 mentioned above. At the same time, it can also provide a certain support for the roller shaft 251. Compared with the roller shaft 251 fixed on one side, the roller shaft 251 is more evenly stressed.
[0024] To improve sealing, a bottom baffle plate 140 is installed inside the hopper 100. The bottom baffle plate 140 is located below the scraper slide plate 200. Several slide plate guide grooves are provided on the side of the bottom baffle plate 140 facing the scraper slide plate 200. Several slide plate bottom guide strips are provided on the side of the scraper slide plate 200 facing the bottom baffle plate 140, which are adapted to the several slide plate guide grooves. The cooperation between the slide plate bottom guide strips and the slide plate guide grooves can further reduce the lateral movement of the scraper slide plate 200 and improve the operational stability.
[0025] In the operation of the rear-loading compression garbage truck sliding plate mechanism in this embodiment, the two sliding plate drive devices 300 synchronously drive the scraper sliding plate 200 to reciprocate along the roller guide groove 110. During the movement of the scraper sliding plate 200, the support roller 252 provides guidance and bottom support, while the reinforcing plate side support ball 240 and the roller side support ball 253 provide side support on both sides. The multi-directional support ensures that the scraper sliding plate 200 will not deviate significantly after long-term reciprocating movement. At the same time, the actuating part reinforcing plate 230 can improve the strength of the actuating connection position and prevent deformation. The above structures together improve the operational stability and durability of the scraper sliding plate 200.
