[0001] The present invention relates to the field of hooklifts, and in particular to a drainage system and method for a garbage collection box of a hooklift and the garbage collection box. Background Art

[0002] The garbage collection box of the hooklift truck is usually provided with a drain pipe with a drain valve at the bottom of the box body. In the prior art, the staff is required to manually open the drain valve to connect the drain pipe, which is very inconvenient. In addition, since the site is usually slippery, it is easy to slip and fall accidents.

[0003] In addition, the garbage collection box typically has a rear door for dumping garbage and a secondary rear door for keeping the rear door sealed relative to the box body when the rear door is closed. In the prior art, hydraulics are usually used to drive the opening and closing of the rear door and the secondary rear door. Specifically, the box body is usually equipped with a hydraulic quick-connect connector, which is connected to the hydraulic pipeline of the boom truck loaded with the garbage collection box. The staff is required to manually plug and unplug the hydraulic quick-connect connector to obtain hydraulic power from the boom truck or cut off the hydraulic power from the boom truck. In addition, the hydraulic pipeline that drives the opening and closing of the rear door and the secondary rear door is equipped with a ball valve, and the staff is required to manually reverse the ball valve to switch the opening and closing of the rear door and the secondary rear door. Therefore, it is also very inconvenient to complete the opening and closing of the box body rear door and the secondary rear door of the garbage collection box.

[0029] Figure 11 shows a three-dimensional view of a garbage collection box according to the present invention. The garbage collection box 10 according to the present invention includes a box body 20, which is shown in the figure as being formed in a substantially cylindrical shape, but in fact its shape is not limited thereto. The box body 20 is formed with an internal space for accommodating garbage, and the rear end of the box body 20 is provided with a rear door 21 that can be opened and closed and a secondary rear door 22 for keeping the rear door 21 sealed relative to the box body 20 when the rear door 21 is closed. The structures of the box body 20, the rear door 21 and the secondary rear door 22 are known in the art, and thus will not be described in detail herein.

[0030] Figure 1 Also shown is a drainage system 100 and a power supply system 200 of the garbage collection box 10 for the hooklift, which are arranged on the side of the box 20 near the bottom of the box 20. It should be noted that although Figure 1 2 , the drainage system 100 is shown to be located on one side of the housing 20, but it can actually be arranged simultaneously, for example symmetrically, on both sides of the housing 20. Details of the drainage system 100 and the power supply system 200 will be described below.

[0031] FIG. 2A to FIG. 2C The three-dimensional views of the drainage system of the garbage collection box of the hooklift according to the present invention in different states are respectively shown. In which, the box body 20 is shown to include a drainage pipe 24 extending from a part 23 of the side of the box body 20 close to the bottom of the box body 20 to discharge the liquid contained in the internal space of the box body 20, and the drainage pipe 24 is provided with a drainage valve (not shown in the figure) that can be controlled to start and cut off the discharge of the liquid through the drainage pipe 24. The drainage system 100 according to the present invention mainly includes:

[0032] a base 110 , which is intended to be fixed to the ground or a platform;

[0033] a drain pipe connector 120, comprising a fastening device 121 fastened around the drain pipe 24 and a link device 122 passing through the fastening device 121 and attached to a drain valve in the drain pipe 24, wherein the link device 122 is pivotable relative to the fastening device 121 and one end of the link device 122 is arranged to abut against the base 110 and remain stationary during a drain operation, so that when the link device 122 abuts against the base 110 and pivots relative to the fastening device 121, the drain pipe 24 moves in translation relative to the base 110 and the drain valve switches between an open state and a closed state;

[0034] A receiving tube 130 having a receiving end 131 and a discharge end 132, wherein the receiving end 131 is arranged to be movable translationally relative to the base 110 along the same axis as the drain pipe 24, and when the drain pipe 24 and the receiving tube 130 are translated relative to the base 110 so that the two are aligned and connected, the connecting rod device 122 pivots to put the drain valve in an open state, so that the liquid from the internal space of the box body 20 flows through the drain pipe 24 and the receiving tube 130 and flows out from the discharge end 132 of the receiving tube 130.

[0035] The base 110 is provided with a first fixing structure 111 attached to its top surface. During the drainage process, the end of the connecting rod device 122 is intended to hit the first fixing structure 111 and the end is kept stationary against the first fixing structure 111, while the connecting rod device 122 pivots relative to the fastening device 121, so the first fixing structure 111 can also be called a bumper. The base 110 is also provided with a second fixing structure 112 attached to its top surface, such as a fixing plate, which is configured to hold a receiving ring 113, and the receiving tube 130 is arranged to pass through the receiving ring 113 to be movable relative to the base 110 in translation along the same axis as the drain pipe 24.

[0036] The fastening device 121 of the drain pipe connector 120 can be configured as a ring that surrounds the drain pipe 24 and is fixed relative to the drain pipe 24. Therefore, when the connecting rod device 122 pivots relative to the fastening device 121 and drives the fastening device 121 to move in translation, the drain pipe 24 also moves in translation.

[0037] The connecting rod device 122 may be formed, for example, as FIG. 2A to FIG. 2C The connecting rod 122 can be attached to the drain valve through the fastening device 121 and one end of the connecting rod 122 is intended to abut against the first fixing structure 111 during the draining process. FIG. 2A to FIG. 2C It is shown that the linkage 122 is pivotable relative to the fastening device 121 around a first nut 122 a while one end of the linkage 122 is provided with a second nut 122 b intended to abut against the first fixing structure 111 .

[0038] It should be noted that it is preferred that during drainage, the extension direction of the central axis of the drain pipe 24 and the central axis of the annular fastening device 121 is parallel to the length direction of the first fixing structure 111, and parallel to the longitudinal direction, i.e., the front-rear direction, of the box body 20. Thus, it can be ensured that when the second nut 122b of the connecting rod device 122 abuts against the first fixing structure 111, the pivoting of the connecting rod device 122 around the first nut 122a is always along a specific direction (i.e., the length direction of the aforementioned first fixing structure 111 or the longitudinal direction of the box body 20), thereby ensuring the alignment of the drain pipe 24 with the receiving pipe 130.

[0039] Before drainage, the box 20 is usually unloaded from the boom truck, and the pulley at the bottom of the box 20 is placed on a track laid on the ground and slidable along the track, wherein the track is located adjacent to the base 110 of the drainage system 100. In this case, the arrangement position of the base 110 can be predetermined so that when the base 110 is fixed to the ground or the platform, the length direction of the first fixing structure 111 located on the top surface of the base 110 is parallel to the extension direction of the track, that is, parallel to the longitudinal direction of the box 20, that is, also parallel to the extension direction of the central axis of the drainage pipe 24. Therefore, when the box body 20 slides along the track on the ground, one end of the connecting rod device 122 is pivotally connected to the fastening device 121 that moves with the box body 20 while the other end abuts against the first fixed structure 111 that remains stationary, so that the connecting rod device 122 pivots around the first nut 122a, causing the drain pipe 24 to move in a specific direction, i.e., the longitudinal direction of the box body 20, and the drain valve in the drain pipe 24 attached to the connecting rod device 122 is opened or closed.

[0040] The power required for the translational movement of the drain pipe 24 can be provided by a compressor configured to compress the garbage in the internal space of the box body 20. Generally, when the pulley at the bottom of the box body 20 is placed on the track, the compressor is placed at the rear of the box body 20 in the longitudinal direction, for example, directly behind the rear door 21, and the compressor is generally configured to pull the box body 20 backward along the longitudinal direction of the box body 20 to engage with the box body 20, and when the rear door 21 and the secondary rear door 22 are opened, the compressor can compress the garbage contained in the internal space of the box body 20. After the drainage system 100 according to the present invention is provided, when the compressor pulls the box body 20 backward, the drain pipe 24 moves backward along the longitudinal direction of the box body 20 with the box body 20, and at the same time, the second nut 122b mounted to the connecting rod device 122 abuts against the first fixing structure 111 of the base 110 and does not move, while the connecting rod device 122 pivots relative to the fastening device 121 around the first nut 122a ( FIG. 2A to FIG. 2C The drain valve in the drain pipe 24 is opened until the drain pipe 24 is aligned with the receiving pipe 130 and a connected liquid passage is formed. The drain valve is opened to the maximum extent (rotated 90 degrees) so that the liquid in the internal space of the box body 20 can be discharged through the liquid passage.

[0041] That is to say, with the drainage system 100 according to the present invention, when drainage is required, there is no need to manually operate the drain valve to open, but the staff drives the translational movement of the drain pipe 24 and the opening of the drain valve in the process of operating the compressor to pull the box 20 to compress the garbage in the internal space of the box 20. Therefore, it is very convenient and labor-saving to use the drainage system 100 according to the present invention to perform drainage operations, and the risks of slipping and the like caused by manual operation of the drain valve can be avoided.

[0042] The receiving ring 113 and the second fixing structure 112 may be integrated, and the second fixing structure 112 may be integrated with the base 110. However, the receiving ring 113 may also be configured as an independent component and held by the second fixing structure 112, and the second fixing structure 112 may also be configured as an independent component and fixed to the top surface of the base 110, and may be as Figures 2A to 2C As shown, a plurality of reinforcing plates are provided for reinforcing the fixation of the second fixing structure 112 relative to the base 110 .

[0043] The receiving ring 113 is dimensioned such that during drainage its centre axis is coaxial with the centre axis of the fastening device 121. Thereby, alignment of the drainage pipe 24 and the receiving pipe 130 can be ensured.

[0044] Preferably, the drain valve is in a fully open state, i.e., opened to the maximum extent, when the drain pipe 24 and the receiving pipe 130 are aligned and connected. To this end, the connecting rod device 122 can be designed accordingly, so that from the moment when the connecting rod device 122 starts to pivot to drive the drain valve to open and drive the drain pipe 24 to move in translation until the drain pipe 24 and the receiving pipe 130 are aligned and connected, the connecting rod device 122 can just pivot 90 degrees to drive the drain valve to rotate 90 degrees to transform from the initial fully closed state to the final fully open state.

[0045] FIG. 2A to FIG. 2C It is also shown that a first buffer structure 140 may be provided at the end (drain port) of the drain pipe 24 , such as a hemispherical buffer structure shown in the figure, which may be made of a buffer material such as rubber. The first buffer structure 140 may be formed to surround and be fixed to the end of the drain pipe 24 .

[0046] FIG. 2A to FIG. 2C It is also shown that a second buffer structure 150 may be provided at the receiving end 131 of the receiving tube 130. The second buffer structure 150 may be formed to surround and be fixed to the receiving end 131 of the receiving tube 130 and have an inner wall made of a buffer material such as rubber. When the drain pipe 24 and the receiving tube 130 are translated and moved to be aligned and connected, the first buffer structure 140 is received in the second buffer structure 150, thereby forming a liquid channel that is connected and sealed from the outside through the drain pipe 24 and the receiving tube 130.

[0047] FIG. 2A to FIG. 2CAlso shown is a buffer spring 160 that surrounds the receiving tube 130 and is disposed between the second buffer structure 150 and the receiving ring 113. When the compressor pulls the box body 20 backward along the longitudinal direction of the box body 20 to make the drain pipe 24 move backward in translation along the longitudinal direction of the box body 20, the first buffer structure 140 is received in the second buffer structure 150, and the drain pipe 24 continues to move backward in translation along the longitudinal direction of the box body 20, which drives the second buffer structure 150 and the receiving tube 130 to move backward in translation along the longitudinal direction of the box body 20. At this time, by providing the buffer spring 160, it is possible to prevent the second buffer structure 150 from directly hitting the receiving ring 113 and causing the second buffer structure 150 or the receiving ring 113 to be damaged.

[0048] Generally, after the drainage system 100 completes drainage and the compressor completes compression of the garbage in the internal space of the box 20, the compressor will be disengaged from the box 20. At this time, the liquid and garbage in the internal space of the box 20 have been emptied, and the box 20 needs to be placed on the boom truck again with the drainage valve in a fully closed state to prevent liquid from leaking from the drainage pipe 24 during the process of the boom truck receiving the garbage. That is, after the drainage system 100 completes drainage, the drainage valve needs to be reset to a closed state.

[0049] In the present invention, the resetting of the drain valve is achieved by a reset spring 170 disposed between the housing 20 and the drain pipe 24 or the fastening device 121. In the process of the compressor pulling the housing 20 backward along the longitudinal direction of the housing 20 to cause the drain pipe 24 to move backward in translation along the longitudinal direction of the housing 20, the reset spring is stretched until the drain pipe 24 drives the second buffer structure 150 and the receiving tube 130 to move backward in translation to the maximum extent along the longitudinal direction of the housing 20, at which time the reset spring 160 is stretched to the maximum extent and the buffer spring 160 is compressed to the maximum extent. After the drainage process is completed, the compressor pushes the housing 20 forward and disengages from the housing 20, and the end of the connecting rod device 122 no longer abuts against the first fixed structure 111. At this time, the buffer spring 160 compressed to the maximum extent and the reset spring 170 stretched to the maximum extent begin to reset until they return to the maximum extent. Figure 2A It should be noted that during the reset process of the reset spring 170, the reset spring 170 pulls the drain pipe 24 and the fastening device 121 to move forward in the longitudinal direction of the box body 20, thereby driving the connecting rod device 122 to move forward in the longitudinal direction of the box body 20. FIG. 2A to FIG. 2C 1 and 2, and the connecting rod 122 pivots in the counterclockwise direction shown in the figure, so that the connecting rod device 122 drives the drain valve in the drain pipe 24 from the open state to the closed state, and resets to the Figure 2A In this case, the drain valve is in fully closed state.

[0050] It should be noted that Figure 1The state of the box 20 before the drainage process is performed using the drainage system 100 of the present invention is shown, at which time the link device 122 has not yet been arranged to abut against the first fixing structure 111 of the base 110 and the drainage valve is in a completely closed state.

[0051] Figure 2A The state at the beginning of the drainage process is shown, wherein the end of the link device 122 has been arranged to abut against the first fixed structure 111 of the base 110, but has not yet started to pivot. At this time, the drain pipe 24 has not started to move in translation, and the drain valve in the drain pipe 24 is still in a fully closed state;

[0052] Figure 2B The state of the drainage process is shown, at this time the compressor is pulling the box 20 backwards, which is Figure 2A Compared with the state shown, the connecting rod device 122 has been pivoted clockwise by a certain angle, and the drain pipe 24 has been translated backward along the longitudinal direction of the box body 20 by a certain distance so that the first buffer structure 140 of the drain pipe 24 is close to the second buffer structure 150 of the receiving pipe 130 but the two have not yet contacted;

[0053] Figure 2C The figure shows a state ready for drainage, at which time the compressor has finished pulling the box body 20 backwards and is ready to compress the garbage in the internal space of the box body 20, and at which time the drain pipe 24 and the receiving pipe 130 are aligned and connected and the first buffer structure 140 has been received by the second buffer structure 150, and the connecting rod device 122 has been pivoted clockwise so that the drain valve is in a fully open state.

[0054] It should be noted that since the compression box pulls the box body 20 to move backward along the longitudinal direction of the box body 20, the process is almost instantaneous. Figure 2A to Figure 2C The state transition is also achieved almost instantaneously, so that when drainage is required, the following can be formed almost instantly: Figure 2C The connected and sealed liquid passages are shown.

[0055] As mentioned earlier, despite Figure 1 Only the drainage system 100 located on one side of the box body 20 is shown in the figure, but in fact the drainage system 100 can be symmetrically formed on both sides of the box body 20. At this time, the components of the drainage system 100 can be symmetrically arranged on both sides of the box body 20.

[0056] In addition, the drainage system 100 according to the present invention may further include a liquid storage tank for receiving the discharged liquid from the discharge end 132 of the receiving pipe 130. Figure 3, which shows a three-dimensional view of a garbage collection box and a liquid storage box according to the present invention. The respective discharge ends 132 of the two receiving pipes 130 are connected to the liquid storage box 300 to discharge the liquid from the internal space of the box body 20 into the liquid storage box 300, thereby forming a fully enclosed drainage in the entire drainage process. The liquid storage box 300 can be placed on the ground. And, for each independent box body 20, it can be as follows Figure 1 As shown, there is no need to equip the corresponding receiving pipe 130. Instead, when drainage is needed, the drainage pipe 24 of the box 20 can be aligned and connected to the receiving pipe connected to the liquid storage tank 300 by the power of the compressor to achieve closed drainage. In other words, the receiving pipe 130 and the liquid storage tank 300 can be common to different boxes. Usually, there will be a situation where multiple boxes drain and unload garbage at the same position. At this time, it is efficient and convenient to provide a receiving pipe 130 and a liquid storage tank 300 that are common to multiple boxes. For example, the liquid storage tank 300 may be filled only after the liquid from multiple boxes has been collected. At this time, the liquid filled in the liquid storage tank 300 can be conveniently emptied at one time.

[0057] The present invention also provides a drainage method for a garbage collection box of a hooklift, comprising:

[0058] Providing a drainage system 100 according to the present invention;

[0059] The box body 20 of the garbage collection box 10 is unloaded from the hooklift and the pulley located at the bottom of the box body 20 is placed on the track laid on the ground adjacent to the base 110 of the drainage system 100;

[0060] Arrange the end of the linkage device 122 of the drainage system 100 to rest against the base 110;

[0061] A compressor configured to compress garbage in the internal space of the box body 20 is placed at the rear of the box body 20 in the longitudinal direction, and the box body 20 is pulled backward along the longitudinal direction of the box body 20 by the compressor, so that the drain pipe 24 is translated backward along the longitudinal direction of the box body 20 and the connecting rod device 122 is pivoted to change the drain valve in the drain pipe 24 from a closed state to an open state, until the drain pipe 24 and the receiving pipe 130 of the drainage system 100 are aligned and connected, so that the liquid from the internal space of the box body 20 flows through the drain pipe 24 and the receiving pipe 130 and flows out from the discharge end 132 of the receiving pipe 130.

[0062] The drainage method according to the present invention may further include:

[0063] After drainage is completed and the compression box finishes compressing the garbage in the internal space of the box body 20, the compressor pushes the box body 20 forward along the longitudinal direction of the box body 20 and disengages from the box body 20, so that the drain pipe 24 moves forward in the longitudinal direction of the box body 20 to disengage from the receiving pipe 130, and the connecting rod device moves away from the base and pivots to change the drain valve in the drain pipe 24 from an open state to a closed state.

[0064] In general, the actions performed by the various components of the drainage system 100 of the present invention described above can be regarded as the execution steps of the drainage method of the present invention.

[0065] The present invention also provides a garbage collection box for a hooklift, namely Figure 1 The garbage collection box 10 shown comprises: a box body 20 with a drainage pipe 24 and a drainage system 100. The details of the box body 20 and the drainage system 100 have been described above and will not be repeated here.

[0066] The garbage collection box according to the present invention may further include a power supply system 200, such as Figure 1 shown. Figure 4 and Figure 5 More details of the power supply system 200 are shown. Figure 4 A front view of a waste collection box according to the present invention is shown; and Figure 5 A top perspective view of a garbage collection box according to the present invention is shown. The power supply system 200 according to the present invention comprises:

[0067] A power plug 210 disposed on the side of the box body 20 near the bottom of the box body 20;

[0068] a power supply socket 220 provided on the hooklift truck and receiving power supplied by the hooklift truck; and

[0069] A power unit 230 is configured to be electrically connected to the power plug 210 and drive the opening and closing of the rear door 21 and the secondary rear door 22 of the box body 20,

[0070] In which, when the box 20 is loaded onto the arm truck, the power plug 210 and the power supply socket 220 are aligned with each other, and in which, after the box 20 is loaded into place on the arm truck by the arm 11 and during the operation of the arm truck, the power plug 210 is automatically inserted into the power supply socket 220, so that the power unit 230 receives the power supplied by the arm truck to drive the opening and closing of the rear door 21 and the auxiliary rear door 22 of the box 20.

[0071] In the prior art, the hydraulic pipelines for driving the opening and closing of the rear door and the auxiliary rear door of the box are equipped with ball valves, and the staff need to manually switch the ball valves to switch the opening and closing of the rear door and the auxiliary rear door.

[0072] The details of the power plug 210 and the power socket 220 are respectively Fig. 6A and Figure 6B Among them, Fig. 6A 2 shows a three-dimensional view of the power plug according to the present invention. It can be seen that the power plug 210 mainly includes a plug guide portion 211 configured to provide a guiding function when being inserted into the power socket 220 and a plug mounting portion 212 for mounting the power plug 210 to the box 20. The plug guide portion 211 can be formed into, for example, a substantially cylindrical shape, and contains a socket portion 223 ( Figure 6B The plug portion 213 is electrically connected to the housing 20 (as shown in FIG. 1 ). The plug portion 213 can be centrally located in the plug guide portion 211, for example. The plug mounting portion 212 is located between the plug guide portion 211 and the housing 20, and is used to mount the plug guide portion 211 to the housing 20. For example, Fig. 6A The installation is achieved by using a plurality of bolts as shown, but the present invention is not limited thereto. Instead, other common installation methods may be used to install the plug guide 211 to the box body 20 .

[0073] Figure 6B 2 shows a three-dimensional view of a power supply socket according to the present invention. It can be seen that the power supply socket 220 mainly includes a socket guide portion 221 configured to provide a guiding function when receiving the power plug 220 and a socket mounting portion 222 for mounting the power supply socket 220 to the boom truck. The socket guide portion 221 can be formed, for example, in a substantially cylindrical shape, and contains a plug portion 213 ( Fig. 6A The socket portion 223 is electrically connected to the socket guide portion 221. The socket portion 223 can be centrally located in the socket guide portion 221. The socket mounting portion 222 is located between the socket guide portion 221 and the hook arm vehicle and is used to mount the socket guide portion 221 to the hook arm vehicle. For example, Figure 6B The installation is achieved by a plurality of bolts as shown, but the present invention is not limited thereto. Instead, other common installation methods can be adopted to install the socket guide 221 to the hooklift.

[0074] The outer diameter of the plug guide portion 211 is designed to be slightly smaller than the outer diameter of the socket guide portion 221, and the plug guide portion 211 and the socket guide portion 221 are intended to be positioned to have a common central axis when the two are docked, so that the plug guide portion 211 can be docked into the socket guide portion 221 to allow the plug portion 213 to be inserted into the socket portion 223, thereby achieving power supply from the boom truck.

[0075] In addition, Fig. 6A and Figure 6B As shown, the end (guide front end) of the plug guide portion 211 can be chamfered outward to form an outer chamfered portion 214, and correspondingly, the end (guide front end) of the socket guide portion 221 can be chamfered inward to form an inner chamfered portion 224. By providing such outer chamfered portion 214 and inner chamfered portion 224, even if there is a small positioning error between the plug guide portion 211 and the socket guide portion 221 (for example, there is a small offset between the central axes of the two), the plug guide portion 211 can be smoothly docked into the socket guide portion 221 so that the plug portion 213 is inserted into the socket portion 223.

[0076] In addition, Fig. 6A and Figure 6B As shown, a positioning protrusion 215 may be formed on the outer wall of the plug guide portion 211, and correspondingly, a positioning groove 225 may be formed on the inner wall of the socket guide portion 221. When the plug guide portion 211 is docked into the socket guide portion 221, the positioning protrusion 215 and the positioning groove 225 are aligned and positioned, and the extending directions of the two are parallel to the central axis of the plug guide portion 211 and the socket guide portion 221. By providing such positioning protrusions 215 and positioning grooves 225, a certain orientation of the plug portion 213 and the socket portion 223 relative to each other can be achieved when the plug guide portion 211 is docked into the socket guide portion 221, thereby ensuring that the plug portion 213 is smoothly inserted into the socket portion 223.

[0077] In order to ensure that the power plug 210 and the power socket 220 are aligned when the box 20 is loaded and in place and to avoid possible rigid collision when the power plug 210 is inserted into the power socket 220, flexible structures can be provided for the power plug 210 and the power socket 220 respectively. Figure 4 As shown, the power plug 210 is attached to the box 20 through the first flexible structure 240, and the power socket 220 is attached to the arm truck through the second flexible structure 250. The first flexible structure 240 and the second flexible structure 250 are made of flexible materials, and can compensate for the position deviation in the axial and radial directions and the axis angle deviation that may exist when the power plug 210 and the power socket 220 are aligned, so as to facilitate the power plug 210 to be smoothly inserted into the power socket 220, and to avoid rigid collision when the power plug 210 is inserted into the power socket 220 to a certain extent.

[0078] In order to further facilitate the smooth insertion of the power plug 210 into the power socket 220, Figure 4 As shown, limiting devices 260 for limiting the position of the box body 20 during being pulled by the pulling arm 11 are arranged on both sides of the chassis beam of the pulling arm truck and on the pulling arm 11 . Figure 4 It is shown that a plurality of stoppers 260 are arranged on the arm 11 on one side. Although not shown in the figure, another plurality of stoppers can be symmetrically arranged on the arm 11 on the other side. With the help of these stoppers 260, it can be ensured that the box 20 moves along a defined track during the process of being loaded onto the arm truck with the help of the arm 11, so as to ensure that the power plug 210 is automatically inserted into the power supply socket 220 when the box 20 is loaded into place. It should be noted that, depending on the length of the arm 11, the number of stoppers 260 can be adjusted accordingly, and the installation position of each stopper 260 can also be appropriately adjusted.
