Description

Technical Field

[0001] The utility model relates to the technical field of forklift auxiliary equipment, and more specifically, it is a waste unloading lengthening device for forklifts. Background Art

[0002] Wastes are often transported by freight trucks with cargo compartments. Especially when recycling waste circuit boards, after being transported to the designated location, the waste circuit boards need to be taken out of the cargo compartment. In the current prior art, often workers use some simple tools to enter the cargo compartment to move the waste circuit boards to the cargo compartment opening, and then use other equipment to transport them away. In this unloading mode, the operators need to repeatedly enter and exit the cargo compartment with tools, which not only has a high working intensity, but also has low efficiency, and is not conducive to protecting the safety of the operators. Content of the Utility Model

[0003] The purpose of the utility model is to provide a waste unloading lengthening device for forklifts, aiming to solve the technical problems such as high working intensity and low efficiency existing in the prior art.

[0004] To solve the above technical problems, the utility model provides a waste unloading lengthening device for forklifts, which includes a mounting seat, a telescopic mechanism, and a discharging mechanism. The mounting seat is provided with a locking component for fixing the mounting seat and a plurality of symmetric mounting holes. The locking component includes a locking portion extending towards the outside of the mounting seat; the telescopic mechanism is arranged on the mounting seat, and the discharging mechanism is connected to the output end of the telescopic mechanism. The telescopic mechanism drives the discharging mechanism to approach or move away from the mounting seat.

[0005] In the above solution, the mounting seat is mounted on the forklift arm of the forklift through the locking component and a plurality of symmetric mounting holes, which is beneficial to improving the connection stability and reliability between the mounting seat and the forklift arm, preventing the device from being damaged due to external force offset, and the mounting seat can be lifted and lowered with the lifting of the forklift arm, which is beneficial to improving the use range of the device during waste unloading; the telescopic mechanism is used to extend the discharging mechanism into the cargo compartment and cooperate with the forklift to take out wastes at various depths inside the cargo compartment, which is beneficial to extending the action range of the device and improving the applicability of the device; the discharging mechanism is used to clamp the wastes and, when the forklift moves, replace manual labor to drag the wastes out of the cargo compartment, effectively reducing the working intensity of the staff, improving their working efficiency, and preventing safety accidents from occurring during the handling of wastes and affecting the personnel inside the cargo compartment.

[0006] Preferably, the telescopic mechanism includes a first-stage telescopic arm, a second-stage telescopic arm, and a third-stage telescopic arm that are sleeved in sequence on the same straight line. The first-stage telescopic arm is connected to the mounting seat, the third-stage telescopic arm is connected to the discharging mechanism, and the first-stage telescopic arm, the second-stage telescopic arm, and the third-stage telescopic arm are slidably connected.

[0007] In the above solution, the first-stage telescopic arm, the second-stage telescopic arm, and the third-stage telescopic arm (hereinafter referred to as each stage of telescopic arm) can, on the one hand, achieve a longer working radius within a limited space, thereby expanding the working range of the machine, enabling the unloading mechanism to enter deeper positions for unloading, which is beneficial to improving the applicability of the unloading mechanism, and can adjust the extended length according to actual needs. This makes the entire device more flexible and variable, capable of adapting to the requirements of different heights and depths of waste materials at various locations inside the cargo box. When not in use, all telescopic arms can be retracted to the shortest state, greatly reducing the space required for storage and facilitating transportation and storage.

[0008] Preferably, a support assembly is provided between the telescopic mechanism and the mounting seat. The support assembly includes multiple support columns and a support bracket. Two ends of the support column are respectively connected to the mounting seat and the first-stage telescopic arm, and the support bracket extends towards the outside of the mounting seat.

[0009] In the above solution, when the output end of the telescopic mechanism extends, the farther it is from the mounting seat, the more the center of gravity will shift towards the outside of the mounting seat, resulting in an increase in the bending moment on the telescopic mechanism, a corresponding increase in the internal stress, and further a decrease in the stability of the telescopic mechanism, and a reduction in the load capacity of the telescopic mechanism. Therefore, on the one hand, the support assembly uses the support bracket to provide a larger contact area between the telescopic mechanism and the mounting seat, providing better support for the telescopic mechanism. On the other hand, the support column is used to provide additional support points, which is beneficial to improving the overall rigidity of the first-stage telescopic arm and further enhancing the load capacity and stability of the telescopic mechanism.

[0010] Preferably, a limit assembly is provided on each of the first-stage telescopic arm, the second-stage telescopic arm, and the third-stage telescopic arm. The limit assembly includes an elastic limiting member and a limit hole that matches the elastic limiting member.

[0011] In the above solution, after the second-stage telescopic arm and the third-stage telescopic arm extend, in order to enable them to maintain the longest extended length during the waste unloading process, the elastic limiting member is used to clamp the limit holes of two adjacent telescopic arms, so that relative displacement cannot occur between each stage of telescopic arm and they will not randomly extend or retract during waste unloading. And when it is necessary to retract each stage of telescopic arm, the elastic limiting member can be retracted from the limit hole to enable each stage of telescopic arm to continue to slide, which is beneficial to improving the telescopic stability and reliability of the telescopic mechanism.

[0012] Preferably, the elastic limiting member includes a fixed cylinder, a limit post that is slidably clamped inside the fixed cylinder, and an elastic member. One end of the fixed cylinder is provided with a limit cover, and the other end is provided with a limit portion. The elastic member is located between the limit cover and the limit post and presses the limit post to move towards the outside of the limit portion.

[0013] In the above solution, the elastic limiting member should ensure that when the secondary telescopic arm and the tertiary telescopic arm extend or retract a certain distance, they can be locked; the elastic member will squeeze the limiting column, causing the limiting column to extend from the limiting portion to pass through and catch the limiting holes on two adjacent telescopic arms, so as to fix these two telescopic arms. The limiting cover and the limiting portion enable the elastic member and the limiting column to slide only in the fixed cylinder and limit the rotation of the limiting column, which is beneficial to providing a stable connection relationship between the telescopic arms at all levels. In addition, the overall structure of the elastic limiting member is simple, which is beneficial to reducing the occupied space and improving the efficiency of loading, unloading and later maintenance.

[0014] Preferably, a limiting groove is provided on one side of the limiting column, and a curved surface portion is provided on the opposite side.

[0015] In the above solution, taking the primary telescopic arm and the secondary telescopic arm as an example, when the secondary telescopic arm extends a certain distance, the elastic limiting member will be triggered, and the limiting column will pass through their limiting holes. At this time, the limiting groove is on the side close to the unloading mechanism, and the curved surface portion is on the opposite side close to the mounting seat. When the secondary telescopic arm continues to extend, the limiting groove will catch the hole wall of the limiting hole and fix the relative position between the secondary telescopic arm and the primary telescopic arm. When the secondary telescopic arm is to be retracted, after applying a certain force to the secondary telescopic arm, the limiting hole will slide relative to the curved surface portion, causing the limiting column to retract into the fixed cylinder, and the primary telescopic arm and the secondary telescopic arm will lose the fixing effect of the elastic limiting member; the same is true when the secondary telescopic arm is retracted into the primary telescopic arm, but at this time the positions of the limiting groove and the curved surface portion are opposite to those described above; it is beneficial to control the telescopic length of the telescopic mechanism and the relative movement between the telescopic arms, prevent the telescopic mechanism from being randomly affected by external interference and resulting in abnormal unloading, and improve the stability and reliability of the connection between the telescopic arms at all levels.

[0016] Preferably, the unloading mechanism includes a mounting frame connected to the output end of the telescopic mechanism, and a plurality of unloading claws spaced on the mounting frame. The plurality of unloading claws extend an arc portion toward the outside of the mounting frame.

[0017] In the above solution, the mounting bracket adopts a hollow frame structure, and the unloading claws are mounted on the frame. This structure is conducive to greatly reducing the weight of the unloading mechanism, thereby reducing the load on the telescopic mechanism and enabling the telescopic mechanism to extend and retract quickly. When the unloading claws drag the waste, if the unloading claws are vertically oriented towards the bottom of the cargo compartment, not only is the contact area with the waste relatively small, but there may also be relatively intense friction with the bottom of the cargo compartment due to the too small contact surface with the cargo compartment, resulting in relatively large vibrations, thus affecting the stability and reliability of the overall structure of the device. Therefore, the arc portion is conducive to increasing the contact area between the unloading claws and the waste, as well as between the unloading claws and the bottom of the cargo compartment, making the process of unloading the waste smoother. In addition, the extension of the arc portion also serves to support the output end of the telescopic mechanism, which can reduce the bending moment and internal stress on the telescopic mechanism and, together with the mounting seat, improve the stability and load-bearing capacity of the telescopic mechanism.

[0018] Preferably, the unloading mechanism further includes an angle adjusting member, which is detachably connected to the output end of the telescopic mechanism, and the mounting bracket is connected to the output end of the angle adjusting member.

[0019] In the above solution, the angle adjusting member can rotate the mounting bracket by a certain angle, and the unloading claws also rotate by a certain angle with the mounting bracket, enabling the waste at the inner corners of the cargo compartment to be removed, and it is also effective for stacked waste, which is conducive to improving the adaptability of the device to complex waste arrangements and storage spaces.

[0020] Preferably, the mounting bracket is provided with through holes, and a plurality of mounting grooves are circumferentially arranged around the edges of the through holes. The plurality of mounting grooves are spaced apart, and the plurality of unloading claws are respectively detachably connected to the plurality of mounting grooves.

[0021] In the above solution, the through holes further reduce the actual weight of the mounting bracket, further reducing the weight of the unloading mechanism, thereby reducing the load on the telescopic mechanism, which is conducive to the quick operation of the telescopic mechanism and extending its service life. The circumferentially arranged mounting grooves can actually arrange multiple groups of unloading claws around the mounting bracket. In combination with the use of the angle adjusting member, it can further improve the adaptability of the device to complex waste arrangements and storage spaces. And when an individual unloading claw is damaged, a group of unloading claws can be replaced in time for unloading, which is conducive to ensuring the normal operation of waste unloading. The detachable unloading claws can, on the one hand, replace the damaged unloading claws in time for convenient subsequent maintenance, and on the other hand, different types of unloading claws can be replaced to adapt to various different wastes.

[0022] Compared with the prior art, the beneficial effects of the present utility model are:

[0023] An installation base with a locking component and multiple symmetric installation holes is used to fix this device on the forklift, which is beneficial to improving the stability and reliability of the connection between this device and the forklift; the telescopic mechanism expands the working range of this device and improves the applicability of this device; the unloading mechanism is used to clamp and drag out the waste. While realizing the unloading of the waste, it replaces manual labor and the tools used by them, which is beneficial to saving labor and tool costs and preventing safety accidents from occurring during the handling of waste and affecting the personnel inside the cargo compartment. All in all, installing this device on the forklift can replace manual unloading of waste, ultimately greatly reducing the labor intensity, improving the work efficiency, and ensuring the safety of the operators.

Detailed Embodiments

[0030] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0031] In the description of the present utility model, it should be understood that terms such as "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for facilitating the description of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0032] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0033] In this embodiment, please refer to Figures 1 to 4 As shown, the present utility model provides a waste unloading lengthening device for a forklift, including a mounting base 100, a telescopic mechanism 200, and a discharging mechanism 300. The mounting base 100 is provided with a locking assembly for fixing the mounting base 100 and a plurality of symmetric mounting holes 110. The locking assembly includes a locking portion 120 extending towards the outside of the mounting base 100. The telescopic mechanism 200 is arranged on the mounting base 100, and the discharging mechanism 300 is connected to the output end of the telescopic mechanism 200. The telescopic mechanism 200 drives the discharging mechanism 300 to approach or move away from the mounting base 100.

[0034] It can be understood that the mounting seat 100 is installed on the forklift through the locking assembly and a plurality of symmetrical mounting holes 110. Specifically, the forklift passes through the mounting hole 110 through the forklift arm, so that the mounting seat 100 and the forklift can only produce relative movement through the mounting hole 110, and the locking portion 120 of the locking assembly extends to the forklift arm of the forklift, and the forklift arm is locked in the locking portion 120 by the bolt and nut. It is equivalent to further limiting the relative movement that can only be produced through the mounting hole 110, so that the mounting seat 100 and the forklift arm cannot move relative to each other, but can be raised and lowered with the lifting and lowering of the forklift arm; the telescopic mechanism 200 is used to allow the unloading mechanism 300 to extend into the cargo compartment and cooperate with the forklift to remove the waste located at various places in the cargo compartment. It should include an extendable or shortened structure, and in order to avoid external interference causing the telescopic failure, it should also include a locking telescopic structure; the unloading mechanism 300 is used to jam the waste, and when the forklift moves, it replaces manual dragging and removing the waste from various places in the cargo compartment.

[0035] In addition, in some embodiments, there may be multiple locking parts, and the multiple locking parts may also be connected by bolts or other components with connection and locking functions, such as buckles and limit pins.

[0036] In this embodiment, refer to Figure 1 and Figure 2 As shown, the telescopic mechanism 200 includes a first-stage telescopic arm 210, a second-stage telescopic arm 220, and a third-stage telescopic arm 230 located on the same straight line and arranged in sequence, the first-stage telescopic arm 210 is connected to the mounting seat 100, the third-stage telescopic arm 230 is connected to the unloading mechanism 300, and the first-stage telescopic arm 210, the second-stage telescopic arm 220, and the third-stage telescopic arm 230 are slidably connected with each other.

[0037] It can be understood that the sliding connection between the first-level telescopic arm 210 and the second-level telescopic arm 220, and between the second-level telescopic arm 220 and the third-level telescopic arm 230 (hereinafter referred to as adjacent telescopic arms) is achieved by setting matching concave-convex structures 2411 on the relative inner and outer surfaces; the relative movement between the adjacent telescopic arms can be performed manually or by hydraulic, pneumatic, or motor drive.

[0038] In addition, in some embodiments, only a first-stage telescopic arm 210 and a second-stage telescopic arm 220 may be provided, or more stages of telescopic arms may be provided, depending on the required range of use and the overall load capacity of the telescopic mechanism 200; the sliding connection may also be provided by providing corresponding guide rails and sliding seats.

[0039] Specifically, a support assembly 130 is provided between the telescopic mechanism 200 and the mounting base 100. The support assembly 130 includes a plurality of support columns 131 and a support bracket 132. The two ends of the support column 131 are respectively connected to the mounting base 100 and the first-stage telescopic arm 210, and the support bracket 132 extends towards the outside of the mounting base 100.

[0040] It can be understood that the farther the output end of the telescopic mechanism 200 is from the mounting base 100 during telescoping, the more the center of gravity will shift towards the outside of the mounting base 100, resulting in an increase in the bending moment on the telescopic mechanism 200 and a corresponding increase in the internal stress, thereby leading to a decrease in the stability of the telescopic mechanism 200 and a reduction in the load capacity of the telescopic mechanism 200. Therefore, on the one hand, the support assembly 130 uses the support bracket 132 to provide a larger contact area between the telescopic mechanism 200 and the mounting base 100, providing better support for the telescopic mechanism 200. On the other hand, the plurality of support columns 131 are used to provide additional support points for the telescopic mechanism 200, which is beneficial to improving the overall rigidity of the first-stage telescopic arm 210 and further enhancing the load capacity and stability of the telescopic mechanism 200.

[0041] In addition, in some embodiments, the support assembly 130 can also be provided at the output end of the telescopic mechanism 200 and extend towards the plane coinciding with the bottom of the mounting base 100 to provide support for both ends of the telescopic mechanism 200.

[0042] Specifically, in combination with Figure 4 As shown, limit assemblies are provided on the first-stage telescopic arm 210, the second-stage telescopic arm 220, and the third-stage telescopic arm 230. The limit assemblies include elastic limit members 240 and limit holes 250 that match the elastic limit members 240.

[0043] It can be understood that there are at least two limit holes 250, which are respectively provided on any side surfaces near the two ends of each stage of telescopic arm. It should be noted that the limit holes 250 of adjacent telescopic arms should be located on the same straight line. This means that when relative movement occurs between adjacent telescopic arms, the limit holes 250 thereon can be located on the same axis due to the movement, so as to ensure that the elastic limit member 240 can be normally triggered and lock the positions between adjacent telescopic arms; the elastic limit member 240 can be provided on the inner and outer surfaces of each stage of telescopic arm and opposite to the limit holes 250, so as to ensure that when the elastic limit member 240 is triggered, it can pass through two opposite limit holes 250 to realize the positioning between adjacent telescopic arms.

[0044] In addition, in some embodiments, the elastic limit member 240 can also be provided between adjacent telescopic arms.

[0045] More specifically, the elastic limiting member 240 includes a fixed cylinder 241, a limiting post 242 and an elastic member 243 that are slidably clamped in the fixed cylinder 241. One end of the fixed cylinder 241 is provided with a limiting cover 244, and the other end is provided with a limiting portion 245. The elastic member 243 is located between the limiting cover 244 and the limiting post 242 and presses the limiting post 242 to move outward toward the outside of the limiting portion 245.

[0046] It can be understood that the fixed cylinder 241 is connected to the limiting holes 250 of each stage of telescopic arm through threaded fit; the limiting post 242 can pass through the opposite limiting holes 250 between adjacent telescopic arms to lock the positions between adjacent telescopic arms; one end of the limiting post 242 can approach or move away from the fixed cylinder 241 from the limiting portion 245, and the other end should be provided with a convex edge that abuts against the limiting portion 245, and when the elastic member 243 pushes the limiting post 242 to extend out of the fixed cylinder 241, the extending length of the limiting post 242 is limited; it should be noted that an uneven structure 2411 for preventing the limiting post 242 from rotating randomly is also provided between the limiting portion 245 and the limiting post 242; the limiting cover 244 can open the fixed cylinder 241 to replace the internal elastic member 243 or limiting post 242, specifically by threaded fit connection; the elastic member 243 can be a compression spring, a disc spring or other components that can apply axial pressure to the limiting post 242 to apply a pre-tightening force to the limiting post 242.

[0047] In addition, in some embodiments, the elastic limiting member 240 can also be a buckle structure, and when the telescopic mechanism 200 is fully extended or retracted, the adjacent telescopic arms are locked by the buckle.

[0048] More specifically, a limiting groove 2421 is provided on one side of the limiting post 242, and a curved surface portion 2422 is provided on the opposite side.

[0049] It can be understood that taking the first-stage telescopic arm 210 and the second-stage telescopic arm 220 as an example, when the second-stage telescopic arm 220 extends a certain distance, the elastic limiting member 240 will be triggered, and the limiting column 242 will pass through their limiting holes 250. At this time, the limiting groove 2421 is on the side close to the unloading mechanism 300, and the curved surface portion 2422 is on the opposite side close to the mounting base 100. When the second-stage telescopic arm 220 is to continue to extend, the limiting groove 2421 will catch the hole wall of the limiting hole 250 and fix the relative position between the second-stage telescopic arm 220 and the first-stage telescopic arm 210. When the second-stage telescopic arm 220 is to be retracted, after applying a certain force to the second-stage telescopic arm 220, the limiting hole 250 will slide with the curved surface portion 2422, causing the limiting column 242 to retract into the fixed cylinder 241, and the first-stage telescopic arm 210 and the second-stage telescopic arm 220 will lose the locking function of the elastic limiting member 240; when the second-stage telescopic arm 220 is retracted into the first-stage telescopic arm 210 and fixed, the principle is the same, but at this time another elastic limiting member 240 is used, and the positions of the limiting groove 2421 and the curved surface portion 2422 on its limiting column 242 should be opposite to the foregoing.

[0050] In this embodiment, with reference to Figure 1 、 Figure 2 and Figure 3 shown, the unloading mechanism 300 includes a mounting frame 310 connected to the output end of the telescopic mechanism 200, and a plurality of unloading claws 320 spaced apart on the mounting frame 310. The plurality of unloading claws 320 extend an arc portion 321 toward the outside of the mounting frame 310.

[0051] It can be understood that the mounting frame 310 is rectangular and adopts a hollow frame structure, and the unloading claws 320 are installed on this frame; the unloading claw 320 is a long strip plate with one end connected to the mounting frame 310 and an arc-shaped panel (i.e., the arc portion 321) at the other end. The plate surface of the long strip plate faces both sides of the mounting frame 310, and the plate edge faces the telescopic direction of the telescopic mechanism 200, and the plate edge abuts against the waste. The arc portions 321 of the plurality of unloading claws 320 extend toward the plane coinciding with the bottom surface of the mounting base 100 and bend and expand toward both sides of the mounting frame 310, while supporting the output end of the telescopic mechanism, increasing the contact area between the unloading claws 320 and the waste (especially the waste printed circuit board), and between the unloading claws 320 and the bottom of the cargo box.

[0052] In addition, in some embodiments, the mounting frame 310 can be circular, elliptical or other shaped structures to facilitate unloading of waste at various places in the cargo box; the plate surface and plate edge orientations of the unloading claws 320 can also be set in the opposite way, that is, using the plate surface to abut against the waste; or the plurality of unloading claws 320 can be set in a shape and structure similar to a broom.

[0053] Specifically, the unloading mechanism 300 further includes an angle adjusting member 330. The angle adjusting member 330 is detachably connected to the output end of the telescopic mechanism 200, and the mounting bracket 310 is connected to the output end of the angle adjusting member 330.

[0054] It can be understood that a space for accommodating the angle adjusting member 330 should be provided at the output end of the telescopic mechanism 200. The angle adjusting member 330 can control the rotation angle of the unloading mechanism 300, which means that the waste materials at various positions inside the cargo compartment can be unloaded at multiple angles.

[0055] More specifically, through holes are provided on the mounting bracket 310, and a plurality of mounting grooves 340 are provided around the edges of the through holes. The plurality of mounting grooves 340 are arranged at intervals, and the plurality of unloading claws 320 are respectively detachably connected to the plurality of mounting grooves 340.

[0056] It can be understood that the through holes of the mounting bracket 310 are provided at the central position of the mounting bracket 310, and the direction of the through holes is consistent with the telescopic direction of the telescopic mechanism 200. The plurality of mounting grooves 340 are arranged around the edges of the through holes. One end of the unloading claw 320 is still connected to the mounting groove 340, and the other end extends outward from the mounting bracket 310 with an arc-shaped portion 321. The difference is that now there are a plurality of unloading claws 320 surrounding the mounting bracket 310. These unloading claws 320 can be of different types, and can quickly adjust the unloading claws 320 to be used or replace the damaged unloading claws 320 in cooperation with the angle adjusting member 330.

[0057] In addition, in some embodiments, since the mounting bracket 310 is a hollow frame structure and is provided with through holes, a connecting member 350 should also be provided at the center of gravity of the mounting bracket 310, so that the output end of the angle adjusting member 330 can pass through the center of gravity of the mounting bracket 310 with the telescopic direction as the axis, preventing irregular rotation from causing changes in the load of the telescopic mechanism 200 by the unloading mechanism 300 and affecting the normal operation of the device.

[0058] The specific application process of the present utility model is as follows:

[0059] When not in use, the telescopic arms of the telescopic mechanism 200 are received on the mounting seat 100, and the unloading mechanism 300 is close to the mounting seat 100.

[0060] In use, pass the forklift arm of the forklift through the mounting hole 110 so that the mounting seat 100 is sleeved on the forklift arm. At this time, the locking portion 120 extends to the rear of the forklift arm and clamps the forklift arm, and use bolts and nuts to fix the forklift arm in the locking portion 120. At this time, the mounting seat 100 is completely fixed on the forklift arm; adjust the height of the forklift arm, align the unloading mechanism 300 with the cargo box, extend the secondary telescopic arm 220 and the tertiary telescopic arm 230, so that the unloading mechanism 300 moves away from the mounting seat 100 and enters the interior of the cargo box. After extending a certain length, the limiting posts 242 in the elastic limiting member 240 pass through the opposite two limiting holes 250 along the specified direction of the concave-convex structure 2411, so that the hole wall of the limiting hole 250 abuts against the limiting groove 2421 to prevent further extension and lock the relative positions of adjacent telescopic arms; adjust the height of the forklift arm again. If the angle of the unloading claw 320 needs to be adjusted, use the angle adjusting member 330 to adjust it. Then lower the unloading claw 320 to the specified position, move the forklift, and drag the waste materials everywhere in the cargo box out of the cargo box.

[0061] After the waste unloading is completed, apply a certain amount of force to the output end of the telescopic mechanism 200. Sliding will occur between the curved surface portion 2422 on the limiting post 242 and the hole wall of the limiting hole 250. At this time, the limiting post 242 is squeezed back into the fixed cylinder 241 along the specified direction of the concave-convex structure 2411, so that adjacent telescopic arms can move relative to each other again and be retracted onto the mounting seat 100.

[0062] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
