[0051] The implementation principle of the warehouse insect-proof mesh cover automatic laying device according to the embodiment one of the present application is as follows:

[0052] Before laying and covering the insect-proof mesh cover for any stack, first, the length of the cross beam 311 and the roll 32 is adjusted by the adjusting motor 313 and the screw rod on the cross beam 311 to adapt to the size width of the insect-proof mesh cover required by the stack; then when the mesh cover is manually wound on the roll 32, first, the counterweight block at the winding end of the mesh cover is clamped and fixed in the embedding groove 3221, and then the driving motor 35 is started to drive the roll 32 to rotate to wind the mesh cover.

[0053] When the mesh cover has been wound on the roll 32 and can be laid, the support 31 is lifted to a height higher than the stack by the lifting device 2, and then the vehicle body 1 is used to transport the mesh cover to one side of the top of the stack; then the roll 32 and the mesh cover are conveyed to the other side of the stack by extending the side beams 312, and in the process of the mesh cover passing through the top of the stack, first, the mesh cover is unwound by the driving motor 35 to be attached to the front side of the stack towards the vehicle body 1, and then the mesh cover is unwound while being conveyed forward, and finally when the mesh cover is unwound from the other side of the stack and is finished, the clamping plate 332 is controlled to release the counterweight block to make the mesh cover sag, so that the mesh cover can be laid on the stack without manual climbing to work at a high altitude, and different sizes of mesh covers can be wound to lay the mesh cover on stacks of different volumes, which is safe and fast.

[0054] Embodiment two, refer to Figure 6 , Figure 7The difference between the embodiment and embodiment one is that the front end of the vehicle body 1 is provided with a roll changing device 4, and the roll changing device 4 comprises a lifting cylinder 41 and a rotating frame 42. The lifting cylinder 41 is vertically upward, and the piston rod end thereof is fixedly connected with a lifting table 411. The rotating frame 42 is rotationally connected to the lifting table 411, and the lifting table 411 is provided with a rotating motor 421 for driving the rotating frame 42 to rotate. A plurality of pneumatic clamping jaws 422 are circumferentially arranged on the rotating frame 42 along the rotation direction thereof, and the pneumatic clamping jaws 422 are symmetrically arranged at two ends of the rotating frame 42 in two groups. The clamping openings of the pneumatic clamping jaws 422 are directed to the outside of the rotating frame 42, and are used for clamping the two ends of the roll 32. The spacing between the two groups of pneumatic clamping jaws 422 is less than the minimum length of the roll 32.

[0055] The roll changing device 4 is located directly below the front section 3121 of the side beam 312. When the side beam 312 is contracted to the shortest length, the clamping openings of one group of pneumatic clamping jaws 422 on the rotating frame 42 are directly opposite the roll 32 mounting position at the foremost end of the upper side beam 312. The lifting cylinder 41 can lift the rotating frame 42 upward to a position where the pneumatic clamping jaws 422 can clamp the roll 32 on the side beam 312, or the rotating frame 42 can be lifted upward to a position where the roll 32 in the pneumatic clamping jaws 422 is located between the two side beams 312.

[0056] The roll 32 in the embodiment is a replacement roll 43, and a plurality of replacement rolls 43 are arranged and clamped on the pneumatic clamping jaws 422. The replacement roll 43 is provided with a pest-proof net cover for paving, and is used for replacing the used roll 32 on the side beam 312 at any time. The replacement roll 43 can have the telescopic structure in embodiment one, and is provided with a positioning structure for limiting the telescopic length, such as a threaded telescopic structure or an elastic protrusion and groove matching structure for realizing multi-stage length positioning. The replacement roll 43 can also be a fixed length that cannot be telescopic. The replacement roll 43 of the two structures is provided with a long groove 432 along the length direction thereof, and three long grooves 432 are circumferentially and uniformly arranged, for placing the counterweight on the pest-proof net cover, thereby facilitating winding.

[0057] The replacement roll 43 of the above two structures can fix replacement rolls 43 of different lengths on different pneumatic clamping jaws 422, so as to replace the net cover of different sizes for the net cover paving of different sizes of stacks.

[0058] Reference Figure 6 , Figure 8The difference between the embodiment and the embodiment one is that the front end of the side beam 312 is provided with two groups of roller receiving devices 5, and the two groups of roller receiving devices 5 are respectively and symmetrically arranged at the front ends of the two front sections 3121. The front section 3121 is connected with the two ends of the winding roller 32 through the roller receiving device 5 to realize quick disassembly connection. The roller receiving device 5 includes an outer fixing sleeve 51, an inner limiting ring 52, a limiting bead 53 and an ejection spring 54. The outer fixing sleeve 51 is annular and rotationally connected to the front end of the front section 3121. The outer fixing sleeve 51 close to the driving motor 35 is fixedly connected with the output shaft of the driving motor 35. A plurality of installation grooves 511 are formed on the inner side of the outer fixing sleeve 51 in the circumferential direction. The number of the ejection spring 54 and the limiting bead 53 is the same as that of the installation groove 511. The ejection spring 54 is placed in the installation groove 511 one by one. The limiting bead 53 is also located in the corresponding installation groove 511 and is pressed on the outer end of the ejection spring 54. The inner limiting ring 52 is fixedly attached to the inner side of the outer fixing sleeve 51. A limiting hole 521 with a smaller diameter than the opening of the installation groove 511 is formed on the inner limiting ring 52 at a position corresponding to each installation groove 511. The end of the limiting bead 53 is ejected from the limiting hole 521, and the inner limiting ring 52 limits the limiting bead 53 from completely coming out of the installation groove 511.

[0059] Reference Figure 7 , Figure 8 The two ends of the replacement roller 43 are integrally formed with a plurality of prismatic limiting heads 431. The number of edges of the limiting head 431 is the same as that of the limiting bead 53. In this embodiment, the limiting bead 53 has six, and the limiting head 431 is a hexagonal prism. When installing the replacement roller 43, the replacement roller 43 is only moved to between the two side beams 312, and the limiting head 431 is aligned with the roller receiving device 5. Then the cross beam 311 is contracted to make the two side beams 312 close, so that the two limiting heads 431 are inserted into the two inner limiting rings 52 respectively, and the limiting bead 53 is pressed against the end face of the limiting head 431. The limiting column cannot completely enter the installation groove 511 due to the pressing of the ejection spring 54, and the longest diagonal line length of the cross section of the limiting head 431 is close to the diameter of the inner limiting ring 52, so that the limiting bead 53 cannot move from one side end face of the limiting head 431 to the other side, realizing the angle limitation between them, so that the roller receiving device 5 can drive the limiting head 431 and the replacement roller 43 to rotate synchronously.

[0060] The implementation principle of the warehouse insect-proof net cover automatic laying device according to the embodiment two is as follows:

[0061] When the replacement roller 43 is to be replaced, the lifting device 2 lowers the side beams 312 and retracts the length of the side beams 312, so that the replacement roller 43 to be removed is located directly above the roller replacement device 4, and a empty pneumatic clamp jaw 422 is rotated to the upper replacement position; then the lifting cylinder 41 raises the empty pneumatic clamp jaw 422 to clamp the upper replacement roller 43, the two side beams 312 are opened through the cross beam 311, so that the replacement roller 43 to be removed is separated from the two side beams 312, the rotating motor 421 drives the rotating frame 42 to rotate, so that the replacement roller 43 to be installed is rotated to the replacement position facing upward, then the two side beams 312 are retracted through the cross beam 311, so that the limiting heads 431 on both sides of the replacement roller 43 to be installed are docked with the roller abutting device 5, finally the pneumatic clamp jaw 422 in the installation position is loosened to release the replacement roller 43, the lifting cylinder 41 lowers the lifting platform 411, and the replacement and installation are completed.

[0062] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
