Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a lifting structure for garbage trucks. Background Technology

[0002] During the garbage truck's garbage dumping operation, the garbage bins need to be tilted to dump the garbage. The rear of the garbage truck is equipped with a lifting structure to facilitate the dumping of the garbage inside the bins. Once the garbage bins are tilted to the appropriate angle by the lifting structure, the garbage inside will automatically dump due to gravity.

[0003] In practical use, due to the diversity and complexity of garbage, some garbage may be sticky and easily adhere to the inner wall of the garbage can, or the garbage may be tangled and squeezed together, creating greater resistance. All of these situations make it impossible for the garbage to slide down smoothly by gravity alone. The existing lifting structure used on garbage trucks can only lift and tilt the garbage can, but it lacks a shaking component to shake the garbage can when dumping. As a result, some garbage will get stuck inside the garbage can and will be difficult to dump out on its own, thus reducing the efficiency of garbage disposal. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lifting structure for garbage trucks, which has the advantage of improving garbage dumping efficiency. It solves the problem that existing lifting structures for garbage trucks can only lift and tilt the garbage bins, lacking a shaking component to shake the garbage bins during dumping, which causes some garbage to get stuck inside the garbage bins and be difficult to dump out on its own, thus reducing garbage disposal efficiency.

[0005] This utility model provides the following technical solution: a lifting structure for a garbage truck, including a garbage bin, a first connecting rod, a first hydraulic cylinder, a second connecting rod, and a first connecting rod. A swaying component is provided on the surface of the first connecting rod. The swaying component includes a first mounting rod fixedly connected to the side wall surface of the first connecting rod. A locking rod is uniformly fixedly connected to the top surface of the first mounting rod, and steel balls are movably connected to the top surface of each locking rod. A fixing rod is uniformly fixedly connected to the bottom surface of the first connecting rod. A second connecting rod is uniformly fixedly connected to the bottom surface of each fixing rod. A first guide groove is provided on the side wall surface of the second connecting rod. A second mounting rod is provided on the side wall surface of the second connecting rod. Limiting rods are provided opposite to the surface of the second mounting rod. A first limiting block is fixedly connected to the side wall surface of the second mounting rod. A drive plate is fixedly connected to the bottom surface of the second mounting rod. A second hydraulic cylinder is fixedly connected to the bottom surface of the second connecting rod. The swaying component effectively solves the problem of garbage residue and improves the garbage dumping effect.

[0006] Preferably, the first connecting rod is fixedly connected between the opposing surfaces of the two first connecting rods. The ends of the first connecting rod, the first hydraulic cylinder, and the second connecting rod away from the first connecting rod are all rotatably connected to the two side surfaces of the garbage truck. The output shafts of the first hydraulic cylinders are rotatably connected to the side wall surfaces of the first connecting rods through couplings. The combined use of the first connecting rod, the first hydraulic cylinder, and the second connecting rod realizes the lifting and tilting function of the garbage bin.

[0007] Preferably, the second mounting rods are all slidably connected to the inside of the first guide groove through the first limiting block, and the output shafts of the second hydraulic cylinders are all fixedly connected to the surface of the drive plate through the coupling. When the second hydraulic cylinders work in conjunction with the drive plate, the reciprocating extension and retraction of the second hydraulic cylinders causes the trash can to shake back and forth through the drive plate, the second mounting rods and the limiting rods, thereby solving the problem of trash residue inside the trash can.

[0008] Preferably, the side wall surface of the second mounting rod is provided with an adjustment component. The adjustment component includes mounting blocks that are fixedly connected to the side wall surface of the second mounting rod. A bidirectional threaded rod is rotatably connected between the opposing surfaces of each pair of mounting blocks. A crank is fixedly connected to one end of each bidirectional threaded rod. A second guide groove is provided on the side wall surface of the second mounting rod. A second limiting block is fixedly connected to the end of each limiting rod near the second mounting rod. The setting of the adjustment component makes the entire device adjustable, adaptable to trash cans of different widths, and improves the practicality of the device.

[0009] Preferably, the limiting rods are all slidably connected inside the second guide groove through the second limiting block, and the limiting rods are set between the opposite surfaces of the two mounting blocks, and the limiting rods play a positioning role for the trash can.

[0010] Preferably, the limiting rods are all threaded onto the surface of the bidirectional threaded rod, and the opposing surfaces of each pair of limiting rods abut against the side wall surface of the trash can.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By using the shaking component, during the garbage truck's lifting of the garbage bin for garbage dumping, the extension and retraction of the output shaft of the second hydraulic cylinder drives the drive plate to reciprocate, thereby causing the second mounting rod to slide in the first guide groove. Due to the limiting rod's limiting effect on the garbage bin, the garbage bin will reciprocate and shake. Under the combined effect of gravity and shaking, the garbage stuck inside the garbage bin can be completely dumped into the garbage truck, avoiding garbage residue, greatly improving the thoroughness of garbage dumping, ensuring the cleanliness of the garbage bin's interior, reducing the workload of subsequent manual cleaning of the garbage bin, and improving garbage disposal efficiency.

[0013] 2. By adjusting the component settings, turning the handle drives the bidirectional threaded rod to rotate. Under the thread action of the bidirectional threaded rod and the guiding action of the second guide groove, the two limit rods can move closer or further apart, thereby adjusting the distance between the two limit rods. This allows the device to clamp and limit garbage bins of different widths regardless of their width, thus enabling the dumping of garbage from bins of different widths. This adjustability allows the device to adapt to various garbage bin sizes, greatly improving its versatility and practicality, and increasing the efficiency and economic benefits of garbage trucks.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3This utility model provides an embodiment of a lifting structure for a garbage truck, including a garbage bin 1, a first connecting rod 2, a first hydraulic cylinder 3, a second connecting rod 4, and a first connecting rod 5. A swaying component 6 is provided on the surface of the first connecting rod 5. The swaying component 6 includes a first mounting rod 61 fixedly connected to the side wall surface of the first connecting rod 5. A snap-fit ​​rod 62 is uniformly fixedly connected to the top surface of the first mounting rod 61. Steel balls 63 are movably connected to the top surface of each snap-fit ​​rod 62. Fixed rods 64 are uniformly fixedly connected to the bottom surface of the first connecting rod 5. A second connecting rod 65 is uniformly fixedly connected to the bottom surface of the fixed rods 64. The second connecting rod 65 has a first guide groove 66 on its side wall surface. A second mounting rod 67 is provided on the side wall surface of the second connecting rod 65. Limiting rods 68 are provided opposite to the surfaces of the second mounting rods 67. First limiting blocks 69 are fixedly connected to the side wall surfaces of the second mounting rods 67. A drive plate 611 is fixedly connected to the bottom surface of the second mounting rods 67. A second hydraulic cylinder 612 is fixedly connected to the bottom surface of the second connecting rod 65. The first connecting rod 5 is fixedly connected between the opposing surfaces of the two first connecting rods 2. The ends of the first connecting rods 2, the first hydraulic cylinder 3, and the second connecting rod 4 away from the first connecting rod 5 are all rotatably connected. On both sides of the garbage truck, the output shafts of the first hydraulic cylinder 3 are rotatably connected to the side wall surface of the first connecting rod 2 via couplings. The second mounting rods 67 are slidably connected inside the first guide groove 66 via the first limiting block 69. The output shafts of the second hydraulic cylinders 612 are fixedly connected to the surface of the drive plate 611 via couplings. The first connecting rod 2, the first hydraulic cylinder 3, and the second connecting rod 4 drive the entire device to lift and tilt, thereby lifting and tilting the garbage bin 1, causing the garbage inside the garbage bin 1 to be lifted, tilted, and dumped into the garbage truck. When the garbage bin 1 is tilted to a suitable angle, the garbage inside the garbage bin 1... Some of the garbage will automatically tip over due to gravity, while the garbage stuck inside the garbage bin 1 cannot be automatically tipped over. At this time, the shaking component 6 is activated. When the output shaft of the second hydraulic cylinder 612 extends or retracts, it can drive the drive plate 611 to reciprocate. In turn, the drive plate 611 drives the second mounting rod 67 to slide in the first guide groove 66. Due to the limiting rod 68 limiting the garbage bin 1, the garbage bin 1 also reciprocates and shakes. At this time, the garbage stuck inside the garbage bin 1 is completely tipped over into the garbage truck under the combined action of gravity and shaking, thus preventing the garbage inside the garbage bin 1 from getting stuck inside the garbage bin 1.

[0020] Please see Figures 1-3An adjustment assembly 7 is provided on the side wall surface of the second mounting rod 67. The adjustment assembly 7 includes mounting blocks 71 that are fixedly connected to the side wall surface of the second mounting rod 67. A bidirectional threaded rod 72 is rotatably connected between the opposing surfaces of each pair of mounting blocks 71. A crank 73 is fixedly connected to one end of each bidirectional threaded rod 72. A second guide groove 74 is provided on the side wall surface of the second mounting rod 67. A second limiting block 75 is fixedly connected to the end of each limiting rod 68 near the second mounting rod 67. The limiting rod 68 is slidably connected to the inside of the second guide groove 74 through the second limiting block 75. The limiting rod 68 is positioned between the opposing surfaces of each pair of mounting blocks 71. The limiting rods 68 are all threadedly connected to the surface of the bidirectional threaded rod 72. The opposing surfaces of each pair of limiting rods 68 abut against the side wall surface of the garbage can 1. When it is necessary to dump garbage into garbage cans 1 of different widths, the crank handle 73 is turned, which drives the bidirectional threaded rod 72 to rotate. At this time, under the action of the threads of the bidirectional threaded rod 72 and the guidance of the second guide groove 74, the two limiting rods 68 move closer or further apart, and the distance between the two limiting rods 68 is adjusted accordingly. This achieves the clamping effect on garbage cans 1 of different widths, thereby realizing the garbage dumping operation inside garbage cans 1 of different widths and improving the practicality of the device.

[0021] Working principle: During operation, the trash can 1 is first placed in a suitable position so that the groove on the side of the trash can 1 can engage with the top of the engaging rod 62. At this time, the steel ball 63 will abut against the inside of the groove on the side of the trash can 1. The trash can 1 is located within the frame formed by the first connecting rod 2, the first connecting rod 5, and the second connecting rod 4, and the opposing surfaces of the two limiting rods 68 abut against the side wall surface of the trash can 1, which plays a certain limiting role for the trash can 1. When it is necessary to empty the trash can 1, the first hydraulic cylinder 3 is activated. The output shaft of the first hydraulic cylinder 3 rotates with the side wall surface of the first connecting rod 2 through the coupling. As the output shaft of the first hydraulic cylinder 3 extends, it pushes the first connecting rod 2 to rotate around its rotational connection point with the two sides of the garbage truck. The rotation of the first connecting rod 2 drives the first connecting rod 5 to move, and the second connecting rod 4 also rotates around its rotational connection point with the two sides of the garbage truck. Under the coordinated action of the first connecting rod 2, the first hydraulic cylinder 3, and the second connecting rod 4, the entire device begins to lift and rotate, thereby driving the garbage bin 1 to lift and rotate. As the first hydraulic cylinder 3 continues to push the first connecting rod 2 to rotate, the entire device drives the garbage bin 1 to continuously lift and rotate until the garbage bin 1 rotates to a suitable angle. At this time, the shaking component 6 also moves accordingly. When the output shaft of the second hydraulic cylinder 612 extends or retracts, it drives the drive plate 611 to reciprocate, thereby causing the second mounting rod 67 to slide within the first guide groove 66. Due to the limiting rod 68 limiting the garbage bin 1, the garbage bin 1 reciprocates and shakes. The steel ball 63 abuts against the groove on the side of the garbage bin 1, reducing wear on the groove on the side of the garbage bin 1 during shaking, thus facilitating the shaking of the garbage bin 1. Under the action of gravity and shaking, the garbage inside the garbage bin 1 is completely dumped into the garbage truck, thus preventing the garbage inside the garbage bin 1 from getting stuck. The internal structure facilitates the emptying of garbage from the inside of the garbage bin 1. When it is necessary to empty garbage from garbage bins 1 of different widths, the limiting rod 68 can be adjusted to limit the width of the garbage bin 1. By turning the crank handle 73, the crank handle 73 drives the bidirectional threaded rod 72 to rotate. When the bidirectional threaded rod 72 rotates, the two limiting rods 68 move closer or further apart under the action of the thread of the bidirectional threaded rod 72 and the guidance of the second guide groove 74, thereby realizing the adjustment of the limiting width of the side wall of garbage bins 1 of different widths, thus realizing the garbage emptying operation inside garbage bins 1 of different widths and improving the practicality of the device.
