Description

Technical Field

[0001] This utility model relates to the field of garbage bin tipping technology, and in particular to a garbage bin tipping device. Background Technology

[0002] With the acceleration of urbanization and the continuous increase in urban population, urban waste management has become an increasingly prominent issue. Traditional manual waste collection methods suffer from drawbacks such as low efficiency and poor sanitation, failing to meet the needs of modern urban waste management. To improve the efficiency and sanitation of waste management, existing technologies utilize waste bin emptying devices.

[0003] Existing garbage bin tipping devices use chains and hydraulic cylinders to transport the garbage bins to the top of a delivery basket, then the hydraulic cylinders tip the bins over to empty the garbage into the delivery basket. However, relying solely on hydraulic cylinders to tip the bins limits the tipping angle and results in a fixed position after tipping. This leads to the problem of garbage remaining inside the bin during tipping. Therefore, there is an urgent need for a new garbage bin tipping device to solve these technical problems.

Through the combined action of the flipping clamping mechanism 2 and the tilting mechanism 3, the trash can 100 can be tilted at any angle while being clamped, through the flipping and tilting actions. In addition, both clamping arms 24 are slidably connected to the first rotating shaft 23, which can also drive the two second arms 242 to rotate, resulting in a compact structure and a high degree of integration.

[0047] Furthermore, the garbage bin tipping device provided by this utility model is small in size and has a wider range of applications, suitable for both large outdoor spaces and small indoor spaces. Additionally, the garbage bin tipping device can be fixed to a garbage truck via the base 1, or it can be fixed to other movable chassis via the base 1.

Each through hole corresponds to a multiple guide portion 252. The through holes and guide portions 252 are slidably connected along the axial direction of the second rotating shaft 26. In this embodiment, the guide portion 252 is a guide rod. With this arrangement, the clamping arm 24 can slide axially on the first rotating shaft 23, and the first rotating shaft 23 can also drive the clamping arm 24 to rotate. In other embodiments, a sliding joint can be provided on the outer wall of the first rotating shaft 23 along the axial direction, and multiple sliding joints can be provided along the circumference of the first rotating shaft 23. The end face of the second rotating shaft 26 is recessed with an insertion groove, the first rotating shaft 23 extends into the insertion groove, and multiple sliding grooves are recessed on the side wall of the insertion groove.

[0050] like Figure 1 and Figure 12 As shown, the top of the trash can 100 is provided with a flange 101. To facilitate gripping the trash can 100 and prevent it from falling during movement, optionally, in this embodiment, the gripper 32 is provided with a locking groove 321. The bottom wall of the locking groove 321 can abut against the side wall of the flange 101 of the trash can 100, and the two oppositely arranged side walls of the locking groove 321 can abut against the top and bottom surfaces of the flange 101, respectively.

[0051] Optionally, in this embodiment, the end of the gripper 32 near the tipping drive assembly 31 is provided with a stop 322, which can abut against the side wall of the flange 101. After the flipping drive assembly 22 drives the first rotating shaft 23 to rotate, causing the two second arms 242 to rotate and flip the trash can 100 to the opening of the transport basket 200, the stop 322 is provided to prevent the trash can 100 from being loosely engaged with the gripper 32 and falling into the transport basket 200.

After the trash dumping operation is completed, the two clamping arms 24 are moved further apart. When the baffle on the clamping arm 24 triggers the first sensor 28, the clamping arm 24 stops moving, thus achieving a reset.

[0054] Optionally, in this embodiment, the first arm body 241 includes a push block 2411 and a connecting frame 2412. The push block 2411 is fixedly connected to the lead screw nut 214, and the connecting frame 2412 is fixed to the push block 2411. The connecting frame 2412 is provided with a clearance hole 2413 to avoid the first rotating drive member 212 or the fixed seat 211. This arrangement ensures the structural strength of the first arm body 241 while saving the space occupied by the first arm body 241. Specifically, the connecting frame 2412 includes two L-shaped plates and a seat. The two L-shaped plates are disposed on both sides of the push block 2411, with one end of the L-shaped plate connected to the push block 2411 and the other end connected to the seat.

[0057] like Figure 8 As shown, optionally, the flipping drive assembly 22 includes a second rotation drive member 221, a transmission gear assembly, and an output gear 222. The second rotation drive member 221 is fixed to the base 1 and can drive the transmission gear assembly to rotate. The output gear 222 meshes with the transmission gear assembly and is fixedly connected to the first rotating shaft 23. Through gear transmission, the rotation angle of the clamping arm 24 can be precisely controlled. In this embodiment, the second rotation drive member 221 is a motor. In addition, to meet the rotational speed requirements of the clamping arm 24, the flipping drive assembly 22 also includes a support base 223, which is fixed to the base 1. The second rotation drive member 221 is fixed to the support base 223.

The third rotation shaft is rotatably connected to the support base 223 through a bearing, and the third gear 226 meshes with the output gear 222.

[0058] like Figure 7 As shown, optionally, the flipping clamping mechanism 2 further includes a second sensor 29, which is communicatively connected to the flipping drive assembly 22 and used to reset the first rotating shaft 23. In this embodiment, the second sensor 29 is fixed to the support base 223. During the flipping of the trash can 100, the flipping drive assembly 22 drives the two second arms 242 to rotate and flips the trash can 100 to the opening of the transport basket 200. After the trash dumping operation is completed, the two second arms 242 rotate in opposite directions. When the baffle on the first rotating shaft 23 triggers the second sensor 29, the two second arms 242 stop rotating, thus achieving a reset.

[0059] like Figure 10As shown, optionally, the tilting drive assembly 31 includes a third rotation drive 311, a first bevel gear 312, and a second bevel gear 313. In this embodiment, the third rotation drive 311 is a motor, fixed to the second arm 242, and capable of driving the first bevel gear 312 to rotate. The first bevel gear 312 meshes with the second bevel gear 313, and the second bevel gear 313 is connected to the gripper 32 via a fourth rotation shaft.

Optionally, in this embodiment, the third rotation drive 311 is disposed on the outer side of the second arm 242, the gripper 32 is disposed on the inner side of the second arm 242, and the fourth rotation shaft passes through the second arm 242, saving space and facilitating the gripping of the trash can 100. Alternatively, the tilting drive assembly 31 can also be a worm gear structure to drive the gripper 32 to rotate. Optionally, the gripper 32 is detachably connected to the fourth rotating shaft, and different shaped grippers 32 can be replaced to meet the emptying needs of more models of trash cans 100.

[0060] Optionally, the dumping mechanism 3 further includes a third sensor 33, which is communicatively connected to the dumping drive assembly 31 and used to reset the gripper 32. In this embodiment, the third sensor 33 is fixed to the third rotation drive member 311. During the dumping of the trash can 100, the dumping drive assembly 31 drives the gripper 32 to rotate and dumps the trash in the trash can 100 into the transport basket 200. After the dumping operation is completed, the gripper 32 rotates in the opposite direction. When the baffle on the second bevel gear 313 triggers the third sensor 33, the gripper 32 stops rotating, thus resetting.

[0061] The working process of the trash can tipping device provided by this utility model is as follows: Figure 11 and Figure 12 As shown, first, position the gripper 32 directly opposite the trash can 100 to be emptied, then activate the clamping drive assembly 21 to clamp the two grippers 32 onto the trash can 100. Figure 13 As shown, the flip drive assembly 22 and the tilt drive assembly 31 then work simultaneously to move the trash can 100 to the opening above the transport frame, as shown. Figure 14 As shown, the final flipping drive assembly 22 and the tilting drive assembly 31 work simultaneously to dump the garbage in the trash can 100 into the transport basket 200.
