Description

Technical Field

[0001] The utility model relates to the technical field of garbage trucks, in particular to a garbage truck with a manually opened and closed rear cover. Background Art

[0002] Garbage trucks are divided into: compression garbage trucks, dump trucks, swing-arm garbage trucks, self-loading garbage trucks, sealed garbage trucks, and pull-arm garbage trucks. Garbage trucks are mainly used for municipal sanitation and large factories and mines to transport various types of garbage, especially for transporting residential garbage. They can compress and crush the loaded garbage to increase its density and reduce its volume, greatly improving the efficiency of garbage collection and transportation.

[0003] In order to avoid the garbage being exposed to the outside during transportation, which would have a bad visual impact on the general public, a rear cover is needed for the sake of aesthetics. However, most garbage trucks with rear covers on the market currently use hydraulic push rods to open and close them. This virtually increases the manufacturing cost and may cause leakage and contamination of hydraulic oil.

[0004] In view of this, there is an urgent need for a garbage truck with a manually opened and closed rear cover. Summary of the invention

[0005] In view of the problems existing in the prior art, the utility model solves the problems with the following technical structure.

Obviously, the described embodiments are only part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this utility model.

[0027] It should be noted that the terms "including" and "having" in the description and claims of this utility model and any of their deformations are intended to cover non-exclusive inclusion. For example, a process, method, device, product or equipment including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or equipment.

[0028] The following further elaborates on this application Figures 1 - 3 with reference to the attached drawings.

[0029] Refer to Figures 1 - 2A garbage truck with a manually opened and closed rear cover plate as shown includes: a carriage 1 and a rear cover plate mechanism. A hatch is provided at the tail of the carriage 1. The rear cover plate mechanism includes a rear cover plate 2, two first connecting rods 3 respectively arranged on both sides of the rear cover plate 2, and two second connecting rods 4 respectively arranged on both sides of the rear cover plate 2. One end of each of the two first connecting rods 3 is rotatably connected to the rear cover plate 2, and the other end is rotatably connected to the carriage 1. One end of each of the two second connecting rods 4 is rotatably connected to the rear cover plate 2, and the other end is rotatably connected to the carriage 1. The first connecting rod 3 is arranged inside the second connecting rod 4. The end of the first connecting rod 3 close to the carriage 1 is the first connection end, and the end of the first connecting rod 3 close to the rear cover plate 2 is the second connection end. When the second connection end moves downward, the rear cover plate 2 approaches the hatch side until it covers the hatch. When the second connection end moves upward, the rear cover plate 2 moves away from the hatch until the second connection end is closer to the front of the garbage truck than the first connection end. Thus, when it is necessary to open the rear cover plate 2, the rear cover plate 2 is lifted upward to rotate the first connecting rod 3 and the second connecting rod 4 until the second connection end of the first connecting rod 3 is closer to the front of the garbage truck than the first connection end (to maintain stability, the first connecting rod 3 can be made to fit on the carriage 1 in this state). At this time, the gravity of the rear cover plate 2 causes the second connection end of the first connecting rod 3 to have a pressure towards the side close to the front of the garbage truck, making the rear cover plate mechanism stable. At this time, the hatch is completely opened. If it is necessary to close the hatch, the rear cover plate 2 is pulled downward to rotate the first connecting rod 3 and the second connecting rod 4 until the rear cover plate 2 covers the hatch. Thus, the opening and closing of the rear cover plate 2 are manually completed without the need for hydraulic drive, reducing the production cost of the garbage truck.

[0030] Reference Figures 1 - 2 As shown, a bent portion is provided between the first connection end and the second connection end, and the inner side of the bent portion faces the second connecting rod 4 side. Thus, not only does the rear cover plate 2 operate more stably, but also the interference between the first connecting rod 3 and the tail of the carriage 1 during movement is reduced.

[0031] Reference Figures 1 - 2 As shown, in order to make the rear cover plate 2 more stable after being completely opened, a spring 5 is provided at the bent portion. The suspended end of the spring 5 is connected to the carriage 1. When the rear cover plate 2 is in the fully open state, the spring 5 is in a stretched state. When the rear cover plate 2 is in the fully opened state, the spring 5 is in a stretched state. At this time, the pulling force of the spring 5 acts on the bent portion of the first connecting rod 3 to keep the first connecting rod 3 in its current state and prevent the rear cover plate 2 from moving under non-human control. The specific connection method between the spring 5 and the first connecting rod 3 is: a connecting plate is provided at the bent portion, a connecting hole is provided on the connecting plate, and one end of the spring 5 passes through the connecting hole. Thus, the spring 5 can be more stably connected to the first connecting rod 3.

[0032] Reference Figure 3As shown in the figure, when the rear cover plate 2 covers the bin opening, in order to prevent the rear cover plate 2 from moving, a locking bar 6 and an eccentric shaft 7 are provided on the rear cover plate 2. The locking bar 6 is slidably arranged inside the rear cover plate 2. A locking hole is provided at the bin opening of the vehicle bin 1. The eccentric shaft 7 rotates (the eccentric shaft 7 is controlled through a through hole opened on the rear cover plate 2 at the position of the eccentric shaft 7), so that the locking bar 6 is inserted into the locking hole or the locking bar 6 is pulled out of the locking hole.

[0033] Further optimized, in order to control the rear cover plate 2 more conveniently, a handle 8 is provided on the side of the rear cover plate 2 away from the vehicle bin 1. The operator can hold the handle 8 to flip the rear cover plate 2.

[0034] In order to ensure the consistency of the relative rotation between the two first link rods 3 and the rear cover plate 2, referring to Figure 2 and Figure 3 As shown in the figure, a first rotating shaft 9 is provided on the rear cover plate 2. The second connection ends of the two first link rods 3 are respectively connected to both ends of the first rotating shaft 9. In this way, by rotating on the rear cover plate 2 through the first rotating shaft 9, the relative rotation of the two first link rods 3 with respect to the rear cover plate 2 is ensured to be synchronous.

[0035] Similarly, in order to ensure the consistency of the relative rotation between the two second link rods 4 and the rear cover plate 2, referring to Figure 2 and Figure 3 As shown in the figure, a second rotating shaft 10 is provided on the rear cover plate 2. The end parts of the two second link rods 4 are respectively connected to both ends of the second rotating shaft 10. In this way, by rotating on the rear cover plate 2 through the second rotating shaft 10, the relative rotation of the two second link rods 4 with respect to the rear cover plate 2 is ensured to be synchronous.

[0036] Further optimized, in order to install the first link rod 3 and the second link rod 4 more firmly on the vehicle bin 1, a first connection seat 11 is provided at the end of the first link rod 3 close to the vehicle bin 1. The first connection seat 11 is arranged on the vehicle bin 1. A second connection seat 12 is provided at the end of the second link rod 4 close to the vehicle bin 1. The second connection seat 12 is arranged on the vehicle bin 1. In this way, the first link rod 3 and the second link rod 4 can rotate stably on the vehicle bin 1.

[0037] The working principle of the present utility model: When it is necessary to open the rear cover plate 2, lift the rear cover plate 2 upward, so that the first link rod 3 and the second link rod 4 rotate until the second connection end of the first link rod 3 is closer to the front of the garbage truck than the first connection end (in order to maintain stability, the first link rod 3 in this state can be attached to the vehicle bin 1). At this time, the gravity of the rear cover plate 2 causes the second connection end of the first link rod 3 to have a pressure towards the side close to the front of the garbage truck, so that the rear cover plate mechanism is kept stable. At this time, the bin opening is completely opened. If it is necessary to close the bin opening, pull the rear cover plate 2 downward, so that the first link rod 3 and the second link rod 4 rotate until the rear cover plate 2 covers the bin opening. In this way, the opening and closing of the rear cover plate 2 are manually completed without the need to be driven by a hydraulic device, reducing the production cost of the garbage truck.

[0038] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
