[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Reference Figure 1-8An embodiment of the present invention provides a fully automatic packaging and stacking device for bundled agricultural film, including a main body 1, on which are arranged an adsorption member 2, a clamping member 3 and a synchronous driving mechanism, wherein the adsorption member 2 is used to adsorb the outer wall of the cargo; two clamping members 3 are provided and are used to clamp the outer wall of the cargo; the synchronous driving mechanism comprises a negative pressure component for extracting air from the adsorption member 2 and a power component for driving the clamping member 3 to clamp the cargo, and the negative pressure component and the power component operate synchronously.

[0034] Specifically, the palletizer can move the goods to the designated position in the vertical and horizontal directions, so that the goods can be stacked together layer by layer and taken out layer by layer when used. This process is called palletizing. In the prior art, bundles of agricultural film are generally cylindrical and are placed in packaging boxes or pallets when they are packaged. In the embodiment of the present invention, the clamping mechanism (that is, the adsorption member 2 and the clamping member 3 and other structures) is arranged on the main body 1, and the main body 1 is installed on the lifting mechanism or the walking mechanism, so that the goods can be moved to the designated position for palletizing after the clamping mechanism clamps the goods. The lifting mechanism and the walking mechanism are both prior art, not shown in the figure, and will not be described here. The innovation of the embodiment of the present invention lies in that the adsorption member 2 and the clamping member 3 are synchronously driven by the negative pressure component and the power component in the synchronous driving mechanism, so that the outer wall of the cargo can be clamped by the clamping member 3 while the adsorption member 2 adsorbs the outer wall of the cargo; the adsorption member 2 can adopt the flexible suction cup structure in the prior art, one end of which is constructed to be open and used to fit the outer wall of the bundled agricultural film (the open end of the flexible suction cup structure can be deformed to fit the bundled agricultural film in an arc shape) or fit the outer wall of the box; the clamping member 3 can adopt the friction plate structure in the prior art, and when the two clamping members 3 clamp the cargo synchronously, they can drive the cargo to be stacked (the two clamping members 3 can clamp the two ends of the bundled agricultural film or the opposite sides of the box); the negative pressure component can be a combination of a hydraulic rod and a needle tube structure, so that the needle tube structure can be controlled by the hydraulic rod The air in the adsorption member 2 is sucked; the power component can directly use the hydraulic rod in the prior art, and the hydraulic rod can drive the clamping member 3 to approach the goods to clamp the goods; the double fixation of the goods by the adsorption member 2 and the clamping member 3 can not only improve the stability when clamping the goods, but also reduce the clamping force of the clamping member 3 on the goods, and try to avoid deformation of the bundled agricultural film or the packaging box. After the adsorption member 2 adsorbs the goods from the top wall of the goods, the clamping force of the clamping member 3 can be reduced as much as possible to avoid damage to the goods; after the main body 1 clamps and fixes the goods, the lifting mechanism and walking mechanism in the prior art can be used to stack the goods; in each embodiment of the present invention, the adsorption member 2 and the clamping member 3 can not only clamp and stack the bundled agricultural film, but also can stack the box where the bundled agricultural film is placed.

[0035] An embodiment of the present invention provides a fully automatic packaging and stacking device for bundled agricultural film. When the main body 1 moves downward toward the goods, the adsorption component 2 will fit against the top wall of the goods, and the two clamping components 3 will move to the two sides of the goods respectively. At this time, the negative pressure component and the power component can be operated synchronously through the synchronous driving mechanism, wherein the negative pressure component can extract the air between the adsorption component 2 and the top wall of the goods to increase the adsorption force between the adsorption component 2 and the goods, and the power component can drive the two clamping components 3 to operate to clamp the two sides of the goods. In this way, the goods can be clamped and fixed by the cooperation of the adsorption component 2 and the clamping component 3, and the clamping component 3 does not need a large clamping force to stably clamp and fix the goods.

[0036] In another embodiment of the present invention, further, an adsorption tube 4 connected to the adsorption component 2 is fixed on the main body 1, and a piston 5 is slidably connected inside the adsorption tube 4. Specifically, the adsorption member 2 is located at the bottom of the main body 1, and the adsorption tube 4 is between the adsorption member 2 and the main body 1. The top end of the adsorption tube 4 is vertically fixed to the main body 1, and the bottom end is fixedly connected to the adsorption member 2; the piston 5 is adapted to the adsorption tube 4, so that the piston 5 can extract the air in the adsorption member 2 or push the air into the adsorption member 2 when sliding along the adsorption tube 4; when the adsorption member 2 hits the top wall of the cargo, the piston 5 moves away from the adsorption member 2 along the adsorption tube 4 (an electric push rod or other mechanism can be provided on the main body 1 to drive the piston 5 to slide along the adsorption tube 4), so as to extract the air between the adsorption member 2 and the cargo through the piston 5, thereby reducing the pressure between the adsorption member 2 and the cargo, and then increasing the adsorption force between the adsorption member 2 and the cargo; conversely, when it is necessary to release the adsorption of the cargo by the adsorption member 2, the piston 5 can push the air between the adsorption member 2 and the cargo along the adsorption tube 4, thereby increasing the pressure between the adsorption member 2 and the cargo, and then reducing the adsorption force between the adsorption member 2 and the cargo, so that the adsorption member 2 can be separated from the cargo. The purpose of such a setting is that the adsorption force between the adsorption component 2 and the goods can be controlled by controlling the position of the piston 5 in the adsorption tube 4, thereby cooperating with the clamping components 3 on both sides to stably clamp and fix the goods, so that the device can perform stacking operations on the goods, thereby improving the stability and applicability of the device.

[0037] As an alternative to the above-mentioned electric push rod driving the piston 5 to slide along the adsorption tube 4, further, a connecting rod 6 is fixed on the piston 5, and the connecting rod 6 extends outside the adsorption tube 4, and the negative pressure component is used to force the connecting rod 6 away from the adsorption part 2. Specifically, a through hole is constructed on the main body 1, and the connecting rod 6 is inserted into the through hole and the end is fixed to the piston 5, and a dynamic sealing structure is arranged between the connecting rod 6 and the through hole, that is, in the process of the connecting rod 6 driving the piston 5 to slide along the adsorption tube 4, the end of the adsorption tube 4 close to the connecting rod 6 is in a sealed state and the pressure changes with the change of the position of the piston 5. When the piston 5 moves away from the adsorption part 2 to extract the air in the adsorption part 2, the pressure at the end of the adsorption tube 4 close to the connecting rod 6 increases. When the piston 5 approaches the adsorption part 2 to push the air into the adsorption part 2, the pressure at the end of the adsorption tube 4 close to the connecting rod 6 decreases. In this embodiment, the negative pressure component forces the connecting rod 6 to move away from the adsorption part 2 to achieve the above-mentioned embodiment. The negative pressure component has the function of extracting the air in the adsorption part 2. The negative pressure component can be a combination of an electric push rod and an extrusion block (not shown). When the negative pressure component is running, the electric push rod and the extrusion block can push the connecting rod 6 away from the adsorption part 2, thereby driving the piston 5 away from the adsorption part 2, and then extracting the air between the adsorption part 2 and the goods through the piston 5. In this process, the pressure at the end of the adsorption tube 4 close to the connecting rod 6 increases. After the electric push rod is reset, the connecting rod 6 loses the resistance of the extrusion block. At this time, the larger pressure at the end of the adsorption tube 4 close to the connecting rod 6 will force the piston 5 and the connecting rod 6 to move to the side of the adsorption part 2, thereby causing the piston 5 and the connecting rod 6 to passively reset, thereby pushing air between the adsorption part 2 and the goods. The effect of such a setting is that when the negative pressure component is running, the connecting rod 6 is resisted and drives the piston 5 to move along the adsorption tube 4, thereby extracting the air in the adsorption part 2 and adsorbing the goods. Conversely, when the negative pressure component is reset, the piston 5 can be passively reset, thereby pushing air into the adsorption part 2 and releasing the adsorption of the goods.

[0038] Preferably, the negative pressure assembly includes a driving rod 7 slidably connected to the main body 1, a wedge bar 8 is fixed on the driving rod 7, and a wedge block 9 is constructed on the connecting rod 6. Specifically, a driving groove is constructed on the main body 1 along its length direction, and the driving rod 7 is slidably connected in the driving groove. The driving force for the driving rod 7 to move along the driving groove can use a linear driving structure in the prior art, such as an electric push rod or a hydraulic rod; the wedge bar 8 is fixed on the side of the driving rod 7 close to the connecting rod 6, and the wedge block 9 is fixed on the side of the connecting rod 6 close to the driving rod 7. The opposite ends of the wedge bar 8 and the wedge block 9 are constructed with mutually matching wedge surfaces. When the driving rod 7 moves away from the center position of the main body 1 along the driving groove, the wedge surface at the end of the driving rod 7 and the wedge surface of the wedge block 9 conflict with each other, so as to force the wedge block 9 to drive the connecting rod 6 and the piston. 5 moves away from the adsorption member 2 along the adsorption tube 4 until the bottom wall of the wedge block 9 relatively contacts the top wall of the driving rod 7, and the piston 5 moves to the limit position away from the adsorption member 2, at which time the pressure and adsorption force between the adsorption member 2 and the cargo reach the maximum; conversely, when the driving rod 7 approaches the center position of the main body 1 along the driving groove, the bottom wall of the wedge block 9 relatively moves away from the top wall of the driving rod 7 until the wedge block 9 and the driving rod 7 are separated after the driving bar is reset. In this process, the piston 5 is passively reset under the influence of the pressure in the adsorption tube 4 (under the influence of the pressure at one end of the adsorption tube 4 close to the connecting rod 6), so as to drive the connecting rod 6 and the wedge block 9 to reset. In this way, the operation of the piston 5 can be controlled by controlling the position of the driving bar to extract the air in the adsorption member 2 or push the air into the adsorption member 2.

[0039] In another embodiment provided by the present invention, further, a pressure relief pipe 10 is fixed on the main body 1, one end of the pressure relief pipe 10 is connected to the adsorption component 2, and a sealing ball 11 is provided at the other end. The main body 1 is provided with an elastic part 12 for forcing the sealing ball 11 to seal the end of the pressure relief pipe 10, and also includes a pressure relief part. In this embodiment, the main body 1 approaches the cargo from above the cargo. During this process, the adsorption member 2 and the top wall of the cargo collide with each other to force the adsorption member 2 to deform and discharge the air in the adsorption member 2. At this time, there is a certain adsorption force between the adsorption member 2 and the cargo. On this basis, the negative pressure component operates and drives the piston 5 away from the adsorption member 2 to further extract the air between the adsorption member 2 and the cargo, so that there is sufficient adsorption force between the adsorption member 2 and the cargo, and the cargo is prevented from falling off the adsorption member 2 as much as possible; on the contrary, when the negative pressure component is reset, the piston 5 is at the end of the adsorption tube 4 close to the adsorption member 2 and cannot continue to approach the adsorption member 2. At this time, there is still a certain adsorption force between the adsorption member 2 and the cargo. If the main body 1 moves upward directly, the adsorption member 2 will be in a negative pressure state, and it will be difficult to drive the adsorption member 2 to separate from the cargo. For this reason, structures such as the pressure relief pipe 10 are provided.Specifically, one end of the pressure relief pipe 10 is connected to the space inside the adsorption piece 2, and the other end extends to the top of the main body 1; the outer wall of the connecting rod 6 is constructed with a flange 25. In this embodiment, the pressure of the adsorption tube 4 close to the end of the connecting rod 6 can force the connecting rod 6 and the piston 5 to move to the end of the adsorption tube 4 close to the adsorption piece 2. At this time, the flange 25 hits the top wall of the main body 1, thereby preventing the piston 5 from continuing to approach the adsorption piece 2. During this process, the piston 5 will not block the end of the pressure relief pipe 10 in the adsorption piece 2; the elastic member 12 is a spring in the prior art, which is in a stretched state and is sleeved on the end of the pressure relief pipe 10. The elastic member 12 is a spring in the prior art. The two ends of the component 12 are respectively fixed to the main body 1 and the sealing ball 11, and the sealing ball 11 can be forced to seal the end of the pressure relief pipe 10 through the elastic component 12; the sealing ball 11 and other structures are staggered with the wedge strip 8, that is, the wedge strip 8 will not contact the sealing ball 11 structure when it moves; the pressure relief component is used to force the sealing ball 11 to move away from the end of the pressure relief pipe 10, such as the combination of an electric push rod and an extrusion block (not shown). When the electric push rod drives the extrusion block to contact the sealing ball 11, the sealing ball 11 moves and moves away from the end of the pressure relief pipe 10, thereby releasing the sealing ball 11 from blocking the pressure relief pipe 10; when the adsorption component 2 and the top wall of the cargo abut against each other, When the suction piece 2 and the cargo are touched, the pressure between the suction piece 2 and the cargo and the pressure in the pressure relief pipe 10 increase simultaneously, thereby forcing the sealing ball 11 to stretch the elastic member 12 and move away from the end of the pressure relief pipe 10, thereby discharging the excess air in the suction piece 2; until the suction piece 2 and the cargo are close to the limit distance, the negative pressure component operates and extracts the air between the suction piece 2 and the cargo through the piston 5. During this process, the sealing ball 11 continues to block the end of the pressure relief pipe 10 under the action of the elastic member 12, and tries to prevent outside air from entering between the suction piece 2 and the cargo, so as to increase the pressure between the suction piece 2 and the cargo and the pressure in the pressure relief pipe 10. The pressure is reduced synchronously, thereby increasing the adsorption force between the adsorbent 2 and the goods; until the goods have completed the stacking operation, the negative pressure component is reset to allow the piston 5 to passively reset to the end of the adsorbent tube 4 close to the adsorbent 2. At this time, the main body 1 directly moves upward, which will cause the adsorbent 2 and the goods to be in a negative pressure state, and it is difficult for the adsorbent 2 to be separated from the goods. In this embodiment, after the negative pressure component is reset, the sealing ball 11 is moved away from the end of the pressure relief pipe 10 through the pressure relief component, so that the space between the adsorbent 2 and the goods is connected to the outside world through the pressure relief pipe 10, so that the main body 1 can move directly upward to drive the adsorbent 2 to separate from the goods. The advantage of such a setting is that by setting the pressure relief pipe 10 and the pressure relief component, it is possible to increase the adsorption force between the adsorbent 2 and the goods while avoiding the situation where the adsorbent 2 cannot be separated from the goods.

[0040] Preferably, the pressure relief member includes a wedge-shaped end 13 fixed on the driving rod 7. Specifically, one end of the pressure relief pipe 10 away from the adsorption member 2 extends to one side of the driving groove, and the wedge-shaped end 13 is fixed to the side of the driving rod 7 close to the sealing ball 11, and the sealing ball 11 is located on the moving stroke of the wedge-shaped end 13, that is, when the driving rod 7 moves along the driving groove, the wedge-shaped end 13 can resist the bottom of the sealing ball 11, so as to force the sealing ball 11 to overcome the elastic force of the elastic member 12 and slightly deviate from the end of the pressure relief pipe 10, thereby releasing the blockage of the pressure relief pipe 10; when the negative pressure component is not running, the driving rod 7 is at the end of the driving groove close to the center of the main body 1, at which time the wedge-shaped end 13 of the wedge block 9 resists the bottom of the sealing ball 11, so that the sealing ball 11 releases the blockage of the pressure relief pipe 10; at the beginning of the operation of the negative pressure component, the wedge block 9 moves away from the sealing ball 11 with the driving rod 7 (such as Figure 2 As shown, the driving rod 7 on the right side moves to the right to move away from the center position of the main body 1, thereby driving the adsorption component 2 on the right side to adsorb the goods. At the same time, the rightward movement of the driving rod 7 on the right side will drive the wedge-shaped end 13 on the right side to separate from the sealing ball 11 on the right side), so that the sealing ball 11 can re-block the pressure relief pipe 10 under the action of the elastic member 12, and then the driving rod 7 continues to move to drive the wedge-shaped strip 8 to resist the wedge-shaped block 9, so as to force the wedge-shaped block 9, the connecting rod 6 and the piston 5 to move to the end away from the adsorption component 2, so as to adsorb the outer wall of the goods through the adsorption component 2; until the main body 1 drives the goods to complete the stacking operation, the driving rod 7 is reset along the driving groove, so that the wedge-shaped strip 8 and the wedge-shaped end 13 are reset, so that the piston 5 can move along the adsorption tube 4 to the side of the adsorption component 2, and at the same time, the sealing ball 11 can be released again through the wedge-shaped end 13 to block the pressure relief pipe 10, so that the space between the adsorption component 2 and the goods is connected to the outside world, so that the main body 1 can directly move upward away from the goods and drive the adsorption component 2 to separate from the goods. Such an arrangement can enable the negative pressure component and the pressure relief component to operate in an adaptive manner, thereby adsorbing or releasing the adsorption of the goods, thereby driving the goods to be stacked stably.

[0041] Furthermore, an extension portion is constructed on the main body 1, a rotating rod 27 is hinged on the extension portion, a through groove 26 is constructed on the rotating rod 27, a limiting rod 24 is slidably connected to the extension portion, the limiting rod 24 has a certain sliding stroke on the extension portion, a protrusion is constructed on the limiting rod 24, the protrusion is slidably connected in the through groove 26, a torsion spring is arranged between the extension portion and the rotating rod 27, the torsion spring can force the rotating rod 27 to move away from one end of the main body 1 toward the sealing ball 11, thereby forcing the protrusion and the limiting rod 24 to slide toward the side of the sealing ball 11 through the inner wall of the through groove 26, so as to limit the sealing ball 11 through the limiting rod 24; the flange 25 is constructed with an inclined surface on the side close to the rotating rod 27. The advantage of such a configuration is that when the connecting rod 6 is away from the adsorption member 2, the flange 25 is separated from the rotating rod 27, and the rotating rod 27 forces the limiting rod 24 to move to the end close to the sealing ball 11 under the action of the torsion spring, so as to limit the sealing ball 11 through the limiting rod 24 and avoid the sealing ball 11 from being removed from the pressure relief pipe 10 as much as possible; when the connecting rod 6 is reset, the flange 25 is reset to a position that fits the top wall of the main body 1, so as to squeeze the end of the rotating rod 27 away from the limiting rod 24 through the inclined surface, thereby forcing the end of the rotating rod 27 close to the limiting rod 24 to approach the connecting rod 6, so that the limiting rod 24 is removed from the sealing ball 11, so that the wedge-shaped end 13 can force the sealing ball 11 to be removed from the pressure relief pipe 10 (such as Figure 4 As shown), in order to adapt to the operation of the elastic member 12 and the wedge-shaped end 13, the sudden pressure release of the adsorption member 2 is avoided as much as possible.

[0042] In another embodiment provided by the present invention, as an alternative solution for the above-mentioned hydraulic rod to drive the clamping member 3 to move, further, two parallel rods 14 are hinged on the main body 1, and the same end of the two parallel rods 14 is hinged to the clamping member 3, and the power assembly is used to drive one parallel rod 14 to rotate. Specifically, the clamping member 3 is arranged vertically to the main body 1 as a whole, and a groove body is constructed on the main body 1 for the parallel rods 14 and the clamping member 3 to move; the two parallel rods 14 have the same length and are arranged parallel to each other, and the same end of the two parallel rods 14 is hinged to the main body 1, and the other end is hinged to the clamping member 3, so that a parallelogram is formed between the two parallel rods 14, the main body 1 and the clamping member 3, that is, when one parallel rod 14 rotates relative to the main body 1, the other parallel rod 14 and the clamping member 3 will move accordingly, so that one parallel rod 14 can be driven to rotate on the main body 1 by the power assembly (the power assembly can use the motor structure in the prior art) to drive the clamping member 3 to move close to the center position of the main body 1 or away from the center position of the main body 1, so as to The two side walls of the goods are clamped or released, and the clamping member 3 will remain perpendicular to the main body 1 during the movement, so as to stably clamp the goods through the side walls of the clamping member 3; for bundles of agricultural film and boxes, the clamping member 3 needs to be kept vertical for clamping, or the clamping member 3 deviates from the vertical state with the main body 1, then the clamping force of different parts of the clamping member 3 on the bundles of agricultural film or the box is different, and even the clamping member 3 only clamps the bundles of agricultural film or the box at one point, which can easily cause damage to the bundles of agricultural film or the box; that is, in this embodiment, the power component drives a parallel rod 14 to rotate to realize the function of the power component driving the clamping member 3 to clamp the goods in the above embodiment.

[0043] As an alternative to the above-mentioned motor structure driving a parallel rod 14 to rotate, preferably, the power assembly includes a rack 15 fixed to the end of the driving rod 7 and a gear 16 fixed to a parallel rod 14. The power assembly and the negative pressure assembly are each provided with two groups. Specifically, the structures such as the adsorption member 2 and the negative pressure assembly are provided with two groups and are symmetrically arranged on both sides of the main body 1, and the power assembly is also provided with two groups and is symmetrically arranged on both sides of the main body 1, so that the two clamping members 3 can be controlled by two groups of power assemblies; the rack 15 and the gear 16 are meshed with each other, and when the negative pressure assembly is running, the driving rod 7 moves away from the center position of the main body 1 along the driving groove to drive the adsorption member 2 to adsorb the goods, and at the same time, the driving rod 7 drives the gear 16 to rotate through the rack 15, so as to drive a parallel rod 14 to rotate on the main body 1, thereby driving the clamping member 3 to approach the center position of the main body 1, so as to clamp and fix the goods under the main body 1 (such as Figure 5 As shown, the rack 15 on the right drives the corresponding gear 16 and parallel rod 14 to rotate clockwise, and finally forms the following Figure 6The state shown in the figure is to clamp the goods); on the contrary, when the driving rod 7 is reset, the adsorption member 2 releases the adsorption of the goods, and the clamping member 3 is reset and releases the clamping of the goods synchronously. The effect of such a setting is that the operation of the adsorption member 2 and the clamping member 3 can be controlled simultaneously by controlling the driving rod 7 to move along the driving groove through the linear driving structure, so that the adsorption member 2 is controlled to adsorb the goods while driving the clamping member 3 to clamp the goods, or the adsorption member 2 is released while releasing the adsorption of the goods, so that the adsorption member 2 and the clamping member 3 can be adapted to operate for palletizing.

[0044] It should be noted that the stroke required for the driving bar to drive the clamping part 3 to clamp the goods through the rack 15 is greater than the stroke required for the driving rod 7 to force the connecting rod 6 to move away from the adsorption part 2 through the wedge bar 8, that is, after the wedge bar 8 forces the connecting rod 6 to move away from the adsorption part 2, the bottom wall of the wedge block 9 abuts against the top wall of the wedge bar 8. At this time, the driving rod 7 can continue to drive the clamping part 3 to move through the rack 15 and other structures, and at the same time drive the wedge bar 8 to continue to move along the driving groove. During the process, the bottom wall of the wedge block 9 moves relatively on the top wall of the wedge bar 8 and maintains the position of the piston 5 in the adsorption tube 4, thereby driving the adsorption part 2 to run at the beginning of the driving bar driving the clamping part 3 to clamp the goods, that is, after the main body 1 moves to the top of the goods, the adsorption part 2 and the clamping part 3 can be driven to run synchronously through the synchronous driving mechanism, and the adsorption part 2 first completes the adsorption of the outer wall of the goods, and the clamping part 3 then completes the clamping of the goods, thereby driving the goods to perform stable stacking operations.

[0045] As an alternative to the above-mentioned linear drive structure controlling the movement of the drive rod 7 along the drive groove, further, two screw rods 17 are rotatably connected to the main body 1, and the two screw rods 17 are respectively threadedly connected to the two drive rods 7. Specifically, the two screw rods 17 are symmetrically arranged on both sides of the main body 1, and the cross-sections of the drive rod 7 and the drive groove are both constructed as non-rotating bodies; the ends of the two screw rods 17 that are close to each other are not provided with a threaded structure and are rotatably connected to the main body 1, and the threaded structures on the two screw rods 17 are symmetrically arranged about the main body 1, so that when the two screw rods 17 rotate in the same direction, they can drive the two drive rods 7 to move synchronously closer to or away from the center position of the main body 1; a connecting shaft 18 is provided on the main body 1, and the connecting shaft 18 is overall constructed in a square frame shape and is located at the center position of the main body 1, and the two sides of the connecting shaft 18 are respectively rotatably connected to the parts of the two screw rods 17 that are not provided with a threaded structure, and holes are constructed on the main body 1 to leak the connecting shaft 18 to avoid interference between the connecting shaft 18 and the main body 1 when the connecting shaft 18 rotates; the two screw rods 17 are symmetrically arranged on the main body 1, and the two screw rods 17 are symmetrically arranged on the main body 1. A transmission gear 19 is fixed at the opposite end of the rod 17, and a connecting gear 20 is rotatably connected to the connecting shaft 18. The connecting gear 20 and the transmission gear 19 are meshed with each other and both are bevel gears in the prior art, so that the connecting gear 20 is tightly meshed with the two transmission gears 19 at the same time, and the two transmission gears 19 are both inside the connecting shaft 18 and do not interfere with the connecting shaft 18; preferably, two connecting gears 20 are arranged, so that the stability of the connection between the connecting shaft 18 and the two screw rods 17 can be further improved; a driving motor 21 is fixed on the main body 1, and a driving wheel 22 is fixed to the output end of the driving motor 21, and a transmission wheel 23 is fixed on the connecting shaft 18, and the driving wheel 22 and the transmission wheel 23 are connected by transmission, such as friction transmission or mechanical transmission.

[0046] Such an arrangement enables the two screw rods 17, the connecting shaft 18 and the main body 1 to rotate relative to each other. When in use, the driving motor 21 can drive the driving wheel 22 to rotate, thereby driving the transmission wheel 23 and the connecting shaft 18 to rotate relative to the main body 1 through the driving wheel 22. When the connecting shaft 18 rotates, it can drive the connecting gear 20 to rotate synchronously around the central axis of the screw rod 17. Since the connecting gear 20 is meshed with the two transmission gears 19 at the same time, the connecting gear 20 can simultaneously drive the two transmission gears 19 to rotate when rotating around the screw rod 17, that is, when the connecting shaft 18 rotates, it can synchronously drive the two screw rods 17 to rotate in the same direction on the main body 1, thereby driving the two driving rods 7 to synchronously approach the center position of the main body 1, and then driving the adsorption member 2 and the clamping member 3 on both sides of the main body 1 to rotate. The goods are adsorbed and clamped; when the driving motor 21 is running, the adsorption component 2 first adsorbs the goods, and the clamping component 3 clamps the goods subsequently. If the goods are directly below the main body 1, after the adsorption component 2 adsorbs the goods, the two clamping components 3 run synchronously to clamp the two side walls of the goods at the same time. If the goods are not directly below the main body 1, the main body 1 will be close to the goods and the adsorption component 2 will be adsorbed at a position deviating from the center of the goods. At this time, if the two clamping components 3 approach synchronously, there will be a relative displacement between the goods and the adsorption component 2, or after one clamping component 3 hits the side wall of the goods, the other clamping component 3 cannot continue to approach the goods and hits the side wall of the goods, which will affect the adsorption or clamping of the goods by the adsorption component 2 and the clamping component 3, and a connecting shaft is provided for this purpose. 18 and other structures; if the cargo is not in the center position of the main body 1, when the driving motor 21 runs and drives the connecting shaft 18 to rotate, the adsorption member 2 can be driven by the driving rod 7 and other structures to adsorb the cargo, and then the driving motor 21 continues to run to drive a clamping member 3 to first contact the side wall of the cargo. At this time, the corresponding screw rod 17 and transmission gear 19 can no longer rotate on the main body 1, and the driving motor 21 can drive the connecting shaft 18 to continue to rotate, so as to drive the connecting gear 20 to roll on the transmission gear 19 that cannot rotate (that is, the connecting gear 20 rotates relative to the connecting shaft 18 and relative to the screw rod 17) and drive the other transmission gear 19 to rotate, thereby driving the other clamping member 3 that does not contact the cargo to continue to move toward the center of the main body 1, so that The connecting shaft 18 only drives the one clamping member 3 that does not interfere with the goods to move, until the other clamping member 3 also interferes with the side wall of the goods and the connecting shaft 18 cannot continue to rotate. At this time, the two clamping members 3 complete the clamping and fixing of the goods deviating from the center of the main body 1; on the contrary, when the driving motor 21 drives the connecting shaft 18 to rotate in the opposite direction, it can drive the two screw rods 17 to rotate in the opposite direction synchronously, so that the two clamping members 3 are synchronously away from the goods to release the clamping and fixing of the goods. Since the moving distances of the two clamping members 3 are different when they approach the center of the main body 1, when the two clamping members 3 are reset synchronously, one clamping member 3 will complete the reset first. At this time, the continuous rotation of the connecting shaft 18 can only drive the other clamping member 3 to continue to reset, until the two clamping members 3 are reset and the connecting shaft 18 stops rotating;Correspondingly, after a clamping member 3 is reset, the corresponding driving rod 7 will complete the reset, so that the corresponding piston 5 and the wedge-shaped end 13 are reset, thereby releasing the adsorption of the corresponding adsorption member 2 on the goods. ;

[0047] The advantage of such a configuration is that when the main body 1 approaches the cargo from above the cargo, the adsorption member 2 first contacts the top wall of the cargo. At this time, the driving motor 21 drives the connecting shaft 18 to rotate, which can synchronously drive the two driving rods 7 away from the center position of the main body 1, so as to drive the two groups of adsorption members 2 and other structures to operate, thereby adsorbing the cargo. Subsequently, the two clamping members 3 operate according to the position of the cargo to clamp the two side walls of the cargo at the same time or clamp the two side walls of the cargo one after another, so as to clamp and fix the cargo without forcing it to move, and try to avoid the situation where the clamping member 3 forces the cargo and the adsorption member 2 to have relative displacement, or one clamping member 3 hits the side wall of the cargo so that the other clamping member 3 cannot continue to approach the cargo. The two clamping members 3 are in contact with the side walls of the cargo; until the two clamping members 3 are in contact with the side walls of the cargo, the driving motor 21 stops running to complete the clamping and fixing of the cargo, which is convenient for the subsequent stacking operation of the cargo; on the contrary, when the driving motor 21 drives the connecting shaft 18 to rotate in the opposite direction, it will drive the two driving rods 7 close to the center position of the main body 1, thereby driving the two clamping members 3 to release the clamping of the cargo, until the two driving rods 7 are completely reset, the two clamping members 3 are reset accordingly and the pressure relief member operates to release the adsorption of the adsorption member 2 on the cargo, which is convenient for the separation of the main body 1 from the cargo; in this way, the cargo can be fixed on the main body 1 or the fixation of the cargo can be released, so as to drive the main body 1 and the cargo to perform stacking operations through the lifting mechanism and the walking mechanism.
