Description

Technical Field

[0001] The utility model relates to the technical field of garbage trucks, in particular to a side-hanging bucket lifting mechanism for a garbage truck. Background Art

[0002] Garbage trucks are mainly used for transporting various types of garbage by municipal sanitation and large factories and mines, and are especially suitable for transporting domestic garbage in residential areas. They mainly improve the efficiency of garbage collection and transportation. There are many types of garbage trucks. The existing self-loading and unloading garbage trucks are mainly equipped with a lifting mechanism with a hanging bucket lifting frame on the side or rear end of the car body to lift the garbage in the garbage bucket and turn it over and pour it into the garbage truck body for unified stacking and unloading.

[0003] The existing side-mounted bucket lifting mechanism of garbage trucks still has some problems when in use. First of all, the existing side-mounted bucket lifting mechanism of garbage trucks mostly uses hydraulic cylinders and sprocket chain transmission to complete the dumping of garbage, but it is inevitable that some garbage sticks to the inside of the garbage bin during dumping, and the garbage is not dumped completely. The traditional method is to repeatedly control the cylinder to operate back and forth to repeatedly dump the garbage, but long-term use can easily cause wear to the transmission mechanism, and the overall use effect is inconvenient. Secondly, the existing garbage trucks have the problem of sudden and large movement when dumping, which can easily damage the clamping joints and the body of the garbage bin, causing waste and reducing the use effect of the lifting mechanism.

The bottom between the two sets of guide rail frames 3 is provided with a mounting top plate 4, and a movable top plate 17 is embedded on the top of the mounting top plate 4. The bottom of the movable top plate 17 is connected to an extrusion column 19, and an extrusion spring 20 is sleeved on the outer side of the extrusion column 19. An embedding groove 18 is provided at the abutment part of the extended end of the extrusion column 19. The embedding groove 18 is mainly used for the movable top plate 17 to enable the extrusion column 19 to move when the trash can is squeezed, so as to facilitate the extrusion movement of the extrusion spring 20 and stabilize the movement limit. The top extension end of the movable top plate 17 is rotatably connected with a first rotating connection member 22 on the upper front side. The first rotating connection member 22 is mainly used to connect the support plate 5 and the movable top plate 17 to facilitate subsequent movement and rotation adjustment. The top extension end of the movable top plate 17 is rotatably connected with a connecting rod 23 on the lower rear side. The front end of the first rotating connection member 22 is connected with the support plate 5. The top rear side of the support plate 5 is connected with a rotating connecting plate 25, which is mainly used to connect 5 and the folding support plate 9, and is convenient for installing two sets of first connecting slide columns 6 located on the guide groove 13 in the guide rail frame 3 to move, which is convenient for subsequent use. The rear end side of the rotating connecting plate 25 is rotatably sleeved with the folding support plate 9, one end of the connecting rotating rod 23 is rotatably connected to the rear side end of the folding support plate 9, and the extrusion column 19 is slidably connected to the inner side of the embedded groove 18. A mounting plate 26 is installed in the middle between the two sets of guide rail frames 3, and the rear end bottom of the mounting top plate 4 is connected to the second rotating connecting member 24. One end of the transmission chain 10 It is connected to the mounting plate 26, and the other end is rotatably connected to the second rotating connecting member 24.

Guide rail grooves 13 are opened on the inner sides of the two groups of guide rail frames 3. The extending ends of the two groups of first connecting slide columns 6 and the two groups of second connecting slide columns 7 are slidably connected to the inner sides of the guide rail grooves 13. When the above-mentioned mechanism components are in operation and use, the garbage bin can stably dump the garbage completely when dumping, reducing the operation of the traditional reusable transmission mechanism, reducing wear and improving convenience of use.

[0033] Embodiment 2:

[0034] Combination Figure 2 and Figure 3 As shown, based on the first embodiment,

[0035] Specifically, the front end of the top of the support plate 5 is connected to a snap-in plate 8, and a protective rubber pad 21 is embedded and installed in the groove of the snap-in plate 8. The use of the above-mentioned components, through the support protection of the foldable support plate 9 and the movable top plate 17 in the implementation column 1, reduces the movement range, reduces damage to the trash can, and improves the use effect.

[0036] Combination Figure 1 and Figure 2 As shown, in the above embodiment,

[0037] Specifically, a connecting support base 12 is installed at the bottom of the electric telescopic cylinder 14. The support base 12 is mainly used to facilitate the installation of the electric telescopic cylinder 14 and connect and fix the two sets of guide rail frames 3 and the two sets of connecting frame plates 2. The connecting support base 12 is connected to the bottom of the two sets of guide rail frames 3 and the two sets of connecting frame plates 2, and the tops of the two sets of guide rail frames 3 are clamped on the top of the carriage 1.

[0038] The working principle and use process of the utility model are as follows: first, when in use, the garbage bin is moved to the upper part of the front end of the clamping plate 8, and the electric telescopic cylinder 14 is opened through the external control device, the telescopic rod 15 is telescopically moved, and the sprocket wheel 16 installed on the U-shaped support plate 11 is meshed and transmitted with the transmission chain 10, driving the mounting top plate 4 connected at one end of the transmission chain 10 through the second rotating connecting member 24 to slide upward along the guide rail groove 13 in the guide rail frame 3, and at the same time driving the movable top plate 17 thereon and the garbage bin clamped by the clamping plate 8 on the support plate 5 to be transferred to the top of the carriage and dumped obliquely toward the direction of the garbage truck. Since the movable top plate 17 on the mounting top plate 4 supports the garbage bin, and since the garbage bin By squeezing the movable top plate 17, the reaction force of the squeezing spring 20 installed in the top plate 4 vibrates the trash can, causing it to discharge the trash into the car by itself. In this way, the trash can be completely discharged, and the operation of the repeated use of the transmission mechanism is reduced to reduce wear and improve ease of use. Secondly, during use, during the operation of the above steps, the folding support plate 9 also rotates to the outlet for dumping the trash can top due to the overall movement, and the protective rubber pad 21 also reduces the damage to the interface of the clamping plate 8 for the trash can. The movable top plate 17 also provides certain support and stability for the trash can. This not only reduces the damage of the lifting mechanism to the trash can and reduces waste, but also improves the overall use effect of the lifting mechanism.
