Description

Technical Field

[0001] This application relates to the technical field of waste disposal equipment, and in particular to a waste bin lifting device with weighing function. Background Art

[0002] Garbage collection trucks are mainly used for municipal sanitation and large-scale factory and mine transportation of various types of garbage. They are particularly suitable for compressing and crushing the loaded garbage, increasing its density and reducing its volume, thus greatly improving transportation efficiency. New types of garbage trucks are characterized by reliable quality, low cost, convenient maintenance, and low operating costs.

[0003] Garbage collection vehicles are generally equipped with an integrated lifting machine, which includes a frame body, a drive mechanism, a lifting mechanism, and a tilting mechanism. The frame body is provided with a first slide rail, and a first slider is provided near the upper part of the tilting mechanism, which is slidably connected to the first slide rail. The tilting mechanism includes a pressure plate, a support plate, and a first vertical rod. The lifting mechanism includes a top plate, a bottom plate, a second vertical rod, and a swing arm. The lifting mechanism is slidably connected to the tilting mechanism and simultaneously to the first slide rail. The drive mechanism pulls the lifting mechanism up and down along the first slide rail through the swing arm. With the cooperation of the top plate and the pressure plate, the lifting mechanism can simultaneously drive the tilting mechanism and the garbage bin to move up and down along the first slide rail and realize garbage dumping. A weighing sensor is installed on the top plate to weigh the garbage bin when it moves up and down along the first slide rail.

[0004] However, in actual use, the pressure applied to the trash can by the pressure plate during weighing causes errors in the weight data of the trash can collected by the weighing sensor. Summary of the Invention

[0005] In order to improve the accuracy of the weight data of the trash can collected by the weighing sensor, this application provides a trash can lifting device with weighing function.

[0006] This application provides a garbage bin lifting device with weighing function, which adopts the following technical solution:

[0007] A trash can lifting device with weighing function includes:

[0008] A lifting track is slidably connected to a first clamping part along its length direction. The first clamping part is slidably connected to a second clamping part. The moving direction of the second clamping part is the direction of the line connecting the first clamping part and the second clamping part.

[0009] A weighing sensor, wherein the weighing sensor is disposed in the second clamping part;

[0010] A driving assembly includes a lifting part and a first driving member. The lifting part is movably disposed on the second clamping part. One end of the lifting part can move toward or away from the first clamping part. The output end of the first driving member is connected to the lifting part. The first driving member is used to drive the lifting part to move.

[0011] By adopting the above technical solution, the second clamping part drives the trash can to move closer to the first clamping part and clamps the trash can together with the first clamping part. Then, the weighing sensor weighs the trash can, and the first driving member drives the lifting part to move closer to the first clamping part, so that the first clamping part disengages from the trash can. At this time, the first clamping part does not apply force to the trash can, thereby reducing the influence of the clamping force of the first clamping part on the weighing data and improving the accuracy of the weighing data. After weighing is completed, the lifting part moves away from the first clamping part, so that the first clamping part and the second clamping part clamp the trash can again and transport the trash can along the lifting track.

[0012] Optionally, the second clamping part has a supporting edge, the output end of the first driving member is slidably connected to the second clamping part in a direction close to or away from the lifting track, and the output end of the first driving member is disposed on one side of the supporting edge. The output end of the first driving member is rotatably connected to one end of the lifting part, and the lower surface of the lifting part abuts against the supporting edge.

[0013] By adopting the above technical solution, when the output end of the first driving member moves, it can drive the second clamping part to rotate around the contact point between the second clamping part and the support edge, thereby causing the end of the lifting part away from the first driving member to move towards the first clamping part or away from the first clamping part.

[0014] Optionally, a first roller is rotatably connected to the end of the lifting part away from the first driving member.

[0015] By adopting the above technical solution, the first roller abuts against the first clamping part, reducing wear between the first clamping part and the lifting part, and improving the smoothness of the lifting part's movement.

[0016] Optionally, the first driving member includes a driving rail and a connecting part. The driving rail is arranged along the length direction of the lifting rail. The driving rail includes a continuous first driving segment, a holding segment, and a second driving segment. The first driving segment and the second driving segment are symmetrically arranged on both sides of the holding segment along the length direction of the lifting rail. The end face of the first driving segment gradually moves away from the lifting rail in the direction close to the holding segment. The distance between the end face of the holding segment and the lifting rail remains unchanged along the length direction of the holding segment. The first driving member can move along the length direction of the driving rail. An elastic element is connected between the connecting part and the second clamping part. One end of the connecting part is rotatably connected to the lifting part, and the other end can move along the end face of the driving rail.

[0017] By adopting the above technical solution, before weighing, the connecting part moves to abut against the first driving section, and then moves along the first driving section to abut against the holding section, causing the connecting part to move away from the lifting track. This causes the connecting part to drive one end of the lifting part to move towards the first clamping part, so that the first clamping part releases its grip on the trash can. At this time, the elastic element undergoes compression deformation. After weighing, the connecting part moves along the second driving section, and the elastic element recovers its deformation, causing the connecting part to move towards the lifting track. This causes the connecting part to drive one end of the lifting part to move away from the first clamping part, so that the first clamping part and the second clamping part clamp the trash can together again, improving the stability of the trash can during the lifting process and reducing the possibility of the trash can falling.

[0018] Optionally, a second roller is rotatably connected to one end of the connecting part, and the second roller is used to abut against the drive rail.

[0019] By adopting the above technical solution, the second roller abuts against the drive rail, which can reduce the wear of the drive rail and the first drive component and improve the smoothness of the first drive component moving along the drive rail.

[0020] Optionally, the first driving component is a motor, the output shaft of the first driving component is rotatable, and the output shaft of the first driving component is fixedly connected to one end of the lifting part, and the rotation axis of the output shaft of the first driving component is inclined to the length direction of the lifting part.

[0021] By adopting the above technical solution, during weighing, the motor drives the lifting part to rotate towards the direction of the first clamping part, so that the first clamping part releases its grip on the garbage can, thereby improving the accuracy of weighing; after weighing is completed, the motor drives the lifting part to rotate away from the first clamping part, so that the lifting part returns to its original position, and the first clamping part and the second clamping part together clamp the garbage can.

[0022] Optionally, the lifting part is slidably connected to the second clamping part, the first driving member is an electric push rod or a cylinder, and the output end of the first driving member moves in the direction of approaching and moving away from the first clamping part.

[0023] By adopting the above technical solution, during weighing, the first driving member drives the lifting part to move towards the first clamping part, so that the first clamping part releases its grip on the garbage can, thereby improving the accuracy of weighing; after weighing, the first driving member drives the lifting part to rotate away from the first clamping part, so that the lifting part resets, and the first clamping part and the second clamping part together clamp the garbage can.

[0024] Optionally, the lifting track is equipped with a second driving component, the output end of the second driving component moves in the direction of the length of the lifting track, the output end of the second driving component is rotatably connected to a sprocket, the sprocket is wound with a chain, and the two ends of the chain are respectively connected to the lifting track and the second clamping part.

[0025] By adopting the above technical solution, the chain can improve the stability of the second clamping part during movement.

[0026] Optionally, the end of the second clamping part facing the first clamping part is fixedly connected with a hanging tooth.

[0027] By adopting the above technical solution, the trash can is snapped into the hook teeth, so that the trash can can be fixed to the second clamping part.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. After the trash can is inserted into the second clamping part, the second clamping part moves towards the first clamping part and clamps the trash can together with the first clamping part. Then, the weighing sensor weighs the trash can, and the first driving member drives the lifting part to move towards the first clamping part, so that the first clamping part is disengaged from the trash can. At this time, the first clamping part does not apply force to the trash can, thereby reducing the influence of the clamping force of the first clamping part on the weighing data and improving the accuracy of the weighing data. After the weighing is completed, the lifting part moves away from the first clamping part, so that the first clamping part and the second clamping part clamp the trash can again and transport the trash can along the lifting track.

[0030] 2. When the output end of the first driving member moves, it can drive the second clamping part to rotate around the contact point between the second clamping part and the support edge, thereby causing the end of the lifting part away from the first driving member to move towards the first clamping part or away from the first clamping part.

[0031] 3. The trash can is snapped into the hook teeth, making it easy to fix the trash can to the second clamping part. Attached Figure Description

Detailed Implementation

[0038] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0039] Example 1:

[0040] This application discloses a garbage bin lifting device with weighing function, referring to... Figure 1 and Figure 2A garbage bin lifting device with weighing function includes a lifting track 1, a second driving component 6, a first clamping part 2, and a second clamping part 3. The lifting track 1 is arranged vertically, and there are two lifting tracks 1 arranged side-by-side. A first support 9 is provided between the two lifting tracks 1, with both ends of the first support 9 slidably connected to the two lifting tracks 1 respectively. The sliding direction of the first support 9 is along the length direction of the lifting track 1. A second support 10 is slidably connected to the first support 9, and the moving direction of the second support 10 is along the length direction of the lifting track 1. The first clamping part 2 is fixedly connected to the first support 9 and is plate-shaped. The second clamping part 3 is located below the first clamping part 2 and includes a base 31 and multiple hanging teeth 33 fixedly connected to the top surface of the base 31. The base 31 is fixedly connected to the second support 10, and a weighing sensor 4 is also fixedly connected to the top surface of the base 31. The second driving component 6 is fixedly connected to the lifting track 1. The second driving component 6 is a cylinder or an electric push rod. The output end of the second driving component 6 moves along the lifting track 1. The output end of the second driving component 6 is rotatably connected to a sprocket 7. The rotation axis of the sprocket 7 is parallel to the line connecting the two lifting tracks 1. A chain 8 is wound around the sprocket 7. One end of the chain 8 is fixedly connected to the lifting track 1, and the other end is fixedly connected to the second clamping part 3.

[0041] The trash can is placed on the ground at the bottom of the lifting track 1. When the trash can is lifted, the second drive component 6 drives the second clamping part 3 to move upward along the lifting track 1 via the chain 8, so that the hook 33 engages with the trash can. Then, the second clamping part 3 drives the trash can upward, so that the second clamping part 3 and the first clamping part 2 together clamp the trash can. After that, the second clamping part 3 continues to move upward, so that the trash can leaves the ground and moves upward. After the trash can leaves the ground, the weighing sensor 4 weighs the trash can simultaneously during the lifting process.

[0042] Reference Figure 2 and Figure 3A garbage bin lifting device with weighing function also includes two symmetrically arranged drive components 5. The drive components 5 include a first drive member 51 and a lifting part 52. In order to clearly explain the connection relationship and positional relationship between the drive components 5 and the second clamping part 3, the structure of one side of the second clamping part 3 and the structure of the drive components 5 located on one side of the second clamping part 3 will be described below. The base 31 has a guide hole 34 along the line connecting the two lifting tracks 1. The top wall of the guide hole 34 has a limiting hole 35 that penetrates the top wall of the guide hole 34. The edge of the opening at the top of the limiting hole 35 away from the lifting track 1 is named the support edge 32. The first driving member 51 is slidably connected to the inner wall of the guide hole 34. The first driving member 51 includes a connecting part 511 and a second roller 55. The connecting part 511 is slidably connected to the inner wall of the guide hole 34. The connecting part 511 is strip-shaped. A through groove is opened in the middle of the connecting part 511. The through groove penetrates the connecting part 511 along the length of the lifting track 1. An elastic member 54 is connected between the inner wall of the through groove and the inner wall of the guide hole 34. One end of the connecting part 511 extends out of the guide hole 34 and is rotatably connected to the second roller 55. The lifting part 52 is rotatably connected to the other end of the connecting part 511. The lifting part 52 is strip-shaped and passes through the guide hole 34 through the limiting hole 35. Under the action of gravity, the lower surface of the lifting part 52 abuts against the support edge 32. The first roller 53 is rotatably connected to the end of the lifting part 52 that passes through the guide hole 34.

[0043] Reference Figure 2 A lifting track 1 is fixedly connected to a drive track 512, and a second clamping part 3 is located between the two drive tracks 512. The structure of the lifting track 1 and the drive track 512 on the same side will be described below. The main body of the drive track 512 is arranged along the length direction of the lifting track 1, and the second clamping part 3 is located between the drive tracks 512. The drive track 512 includes a continuous first drive segment 5121, a holding segment 5122, and a second drive segment 5123. The first drive segment 5121 and the second drive segment 5123 are symmetrically arranged on both sides of the holding segment 5122 along the length direction of the lifting track 1. The end face of the first drive segment 5121 facing the second clamping part 3 is inclined to the end face of the holding segment 5122 facing the second clamping part 3, and the end face of the first drive segment 5121 facing the second clamping part 3 gradually approaches the drive track 512 in a direction away from the holding segment 5122.

[0044] Before weighing, the first clamping part 2 and the second clamping part 3 clamp the trash can and drive the trash can and the first driving member 51 to move upward simultaneously, so that the second roller 55 abuts against the end face of the first driving section 5121 toward the second clamping part 3, and the first driving member 51 moves along the end face of the first driving section 5121 toward the second clamping part 3, so that the first driving member 51 moves toward the direction closer to the limiting hole 35, and the first driving member 51 drives the lifting part 52 to rotate around the support edge 32, so that the first roller 53 located at one end of the lifting part 52 rotates toward the direction closer to the first clamping part 2. When the second roller 55 abuts against the holding section 5122, the lifting part 52 rotates to abut against the first clamping part 2 and lifts the first clamping part 2, so that the first clamping part 2 is disengaged from the trash can. The trash can is no longer subjected to the clamping force of the first clamping part 2, and the elastic member 54 is compressed and deformed. At this time, the weighing sensor 4 weighs the trash can, thereby reducing the influence of the clamping force applied by the first clamping part 2 on the trash can on the measurement results of the weighing sensor 4 and improving the accuracy of the measurement data of the weighing sensor 4.

[0045] After weighing, the second roller 55 moves to the height of the second drive section 5123, and the elastic element 54 recovers its deformation, so that the second roller 55 abuts against the drive rail 512 of the second drive section 5123. As the second roller 55 moves, the connecting part 511 drives the lifting part 52 to rotate away from the first clamping part 2, so that the first clamping part 2 moves towards the second clamping part 3 and together with the second clamping part 3 clamps the trash can, improving the stability of the trash can during the lifting process and reducing the possibility of the trash can falling due to vibration. Furthermore, the movement of the lifting part 52 does not require an additional drive source such as a motor or cylinder. The drive assembly 5 has a compact structure, low cost, and improved practicality.

[0046] The implementation principle of a garbage bin lifting device with weighing function in this application embodiment is as follows: During weighing, the first driving member 51 drives the lifting part 52 to lift the first clamping part 2, thereby reducing the influence of the clamping force applied by the first clamping part 2 on the garbage bin on the weighing data and improving the accuracy of the weighing data. After weighing is completed, the first driving member 51 drives the lifting part 52 to move away from the first clamping part 2, so that the first clamping part 2 and the second clamping part 3 clamp the garbage bin again, improving the stability of the garbage bin lifting process and reducing the possibility of the garbage bin falling.

[0047] Example 2:

[0048] Reference Figure 4The difference between this embodiment and other embodiments is that the first driving member 51 is fixedly connected to the base 31, and the first driving member 51 is a motor. The rotation axis of the motor's output shaft is set in the horizontal direction, and the lifting part 52 is coaxially fixedly connected to the motor's output shaft. The motor's output shaft drives the lifting part 52 to rotate towards or away from the first clamping part 2.

[0049] Example 3:

[0050] Reference Figure 5 The difference between this embodiment and other embodiments is that the first driving member 51 is fixedly connected to the base 31. The first driving member 51 is a cylinder or an electric push rod. The moving direction of the output end of the first driving member 51 is the length direction of the lifting track 1. The lifting part 52 is plate-shaped and fixedly connected to the output end of the first driving member 51. The output end of the first driving member 51 can drive the lifting part 52 to move towards or away from the first clamping part 2.
