The plurality of loading and transporting parts 32 transport the material in the previous bayonet port 311 to the next bayonet port 311, and place the material in the first bayonet port 311 at a distance. Under the action of the subsequent loading and transporting parts 32, the materials are loaded one by one. It should be noted that the clamping end 34 may not be required in the first and last clamping ports 312, so as to facilitate the taking and placing of the materials.

[0035] The material loading and transporting member 32 includes a fixed block 321, a rotating plate 322, an inserting shaft 323 and a clamping cover 324;

[0036] The fixing block 321 is fixed to the side of the base plate 31, the rotating plate 322 is rotatably connected to the fixing block 321, the plug shaft 323 penetrates the rotating plate 322, and is rotatably connected to the rotating plate 322, one end of the plug shaft 323 is fixed to the clamping cover 324, and the other end is fixed to the connecting strip 33, the clamping cover 324 is buckled onto the bayonet 311, the rotating plate 322 rotates, and the reciprocating rotation transfers the material from one bayonet 311 to the next bayonet 311, and is connected through the connecting strip 33, so that the multiple clamping covers 324 move synchronously, continuously transfer the material downward, complete the processing, keep the personnel away from the processing position, avoid danger, and also avoid interference, the structure adopted is also simple, easy to observe intuitively, even if there is a problem in a local position, it can be directly seen, which is convenient for subsequent maintenance;

[0037] A plurality of clamping openings 312 are provided on the inner wall of the bayonet 311, and the height of the plurality of clamping openings 312 is higher than the bayonet 311. A clamping end 34 and a supporting end 35 are provided in the clamping opening 312 and at the lower end of the clamping cover 324, and the clamping end 34 and the supporting end 35 are arranged against each other. The clamping end 34 and the supporting end 35 are mainly used to clamp the material under the action of vibration to avoid the material from being deflected and making subsequent transportation difficult. In addition, in the process of clamping the material, the clamping end 34 and the supporting end 35 provided in the clamping opening 312 and at the lower end of the clamping cover 324 are arranged in an open and closed manner to keep the material in a clamped state to avoid deviation even during transportation.

[0038] The clamping end 34 includes a sleeve shaft 341 and a sleeve 344, the sleeve shaft 341 and the sleeve 344 are sleeved, the end of the sleeve shaft 341 is fixedly sleeved with a force-bearing sleeve 342, one side of the force-bearing sleeve 342 has two 180-degree bevels 343, the end of the sleeve 344 is fixed with a driving strip 345, the driving strip 345 cooperates with the bevel 343, the outer end of the sleeve 344 is also provided with a return spring 346, the return spring 346 is sleeved on the outer side of the sleeve shaft 341, when the sleeve shaft 341 and the sleeve 344 are compressed, the driving strip 345 slides along the bevel 343, the sleeve 344 rotates, and the sleeve 344 is rotated. A hook point 340 is also fixed on the outer side of 44. The rotation of the hook point 340 is used to take and place the material. Through two 180-degree beveled edges 343 on one side of the force-bearing sleeve 342, the driving bar 345 can slide along the beveled edges 343 to realize the rotation of the sleeve 344. After the sleeve 344 rotates, the position of the hook point 340 on its outer wall rotates 180 degrees. The hook point 340 clamps the material or separates from the material, thereby realizing the opening and closing changes. In addition, the height of the clamping port 312 is greater than the bayonet port 311 to ensure that the hook point 340 is hooked at the lower end of the material and can lift the material.

[0039] An edge opening 347 is provided at the end of the hypotenuse 343 of the force-bearing sleeve 342, and an operating rod 348 is fixed on the outside of the sleeve shaft 341. The operating rod 348 extends outward from the edge opening 347, and an operating block 349 is sleeved on the operating rod 348. A torsion spring is installed on the operating rod 348 to drive the operating block 349 to reset. When the operating block 349 resets, it protrudes to one side. When the driving bar 345 slides along the hypotenuse 343, one side of it is first squeezed by the operating block 349. The operating block 349 is used to ensure that the next driving bar 345 cooperates with the oblique lower end of the hypotenuse 343 to ensure that the driving bar 345 slides along the hypotenuse 343 and the sleeve 344 rotates. It should be noted that the torsion spring can only drive the operating block 349 to reset, and will not push the driving bar 345, and its force is small.

[0040] The supporting end 35 includes a circular end 351, which abuts against the outer end of the sleeve 344. The clamping end 34 and the supporting end 35 in the clamping opening 312 are respectively fixed to the inner wall of the clamping opening 312 by the sleeve shaft 341 and the circular end 351. The clamping end 34 and the supporting end 35 at the lower end of the clamping cover 324 are respectively fixed to the clamping cover 324 by the sleeve shaft 341 and the circular end 351, so as to cooperate with the clamping end 34 and make the sleeve 344 of the clamping end 34 rotate.

[0041] The hook points 340 in the clamping opening 312 and the clamping end 34 on the clamping cover 324 are staggered. When the material is taken and placed, the material is transferred so that the hook points 340 in the clamping opening 312 and the clamping end 34 on the clamping cover 324 are staggered to cooperate with the material.

[0042] A linkage part 5 is provided on the outer side of one of the rotating plates 322, and the linkage part 5 includes a support shaft 51, a supporting spring 52, a rack 53, a gear 54 and a connecting shaft 55. One end of the connecting shaft 55 is fixed to the rotating plate 322, and the other end thereof is fixed to the gear 54. The connecting shaft 55 is coaxial with the rotation point of the rotating plate 322. The support shaft 51 is fixed to the lower end of the main shaft 11, the supporting spring 52 is sleeved on the outer side of the support shaft 51, the rack 53 is sleeved on the support shaft 51, and it is against the supporting spring 52, the rack 53 is meshed with the gear 54, and when the main shaft 11 moves, the feeding system 3 is driven to move. The function of the linkage part 5 is to drive the feeding transfer member 32 to move during the drilling process, so as to realize continuous material transmission during the drilling process and adapt to the drilling rate.

[0043] A support part 4 is also installed at the lower end of the main shaft 11. The support part 4 includes a telescopic shaft 41 and a circular pad 42. The telescopic shaft 41 is fixed at the lower end of the main shaft 11 and has a spring inside. The circular pad 42 is fixed at the outer end of the telescopic shaft 41 and is used to extend into the clamping cover 324 to squeeze the material. When drilling the material, the material is squeezed by the circular pad 42 to achieve the extrusion and limiting of the material, thereby reducing human operation as much as possible, and the material is transmitted and drilling is achieved.

[0044] The working principle of the present invention is as follows: when the main shaft 11 moves downward to drill a hole, the support shaft 51 of the linkage part 5 moves downward to drive the material loading and transfer part 32, the rack 53 cooperates with the gear 54, the gear 54 rotates, the rotating plate 322 rotates, and the clamping cover 324 transfers the material to the next bayonet 311. The main shaft 11 moves upward, and the clamping cover 324 returns to the previous bayonet 311 to realize the connection and transfer of the material. In addition, when the main shaft 11 moves downward, the circular pad 42 is against the material, and the telescopic shaft 41 has a telescopic effect. After squeezing and clamping the material, the main shaft 11 can also be kept moving within a certain range to complete subsequent processing. The material can be directly processed after being transferred, saving steps and improving efficiency.

[0045] It should be noted that when the support shaft 51 moves downward, the rack 53 is immobile at first due to the resistance, and then the support spring 52 is squeezed, and the squeezing effect on the rack 53 gradually increases, causing the gear 54 to rotate along the rack 53, completing the loading and transporting function of the loading and transporting member 32, and then resetting, the support shaft 51 moves upward, the rack 53 is abutted against the lower end of the support shaft 51, and the rack 53 is fixed, causing the gear 54 to rotate along the rack 53, causing the main shaft 11 to move a large range, while the gear 54 rotates a small range, and the linked drive loading and transporting member 32 continues to work, and drilling with the main shaft 11 is alternating, thereby maximizing efficiency.

[0046] During the process of the loading and transporting member 32 clamping and transporting the material, the clamping end 34 and the supporting end 35 in the clamping cover 324 and the clamping port 312 are abutted against each other, so that the degree of socketing between the sleeve shaft 341 and the sleeve 344 is increased, the reset spring 346 is squeezed, and the driving bar 345 slides along the bevel 343, so that the sleeve 344 rotates one hundred and eighty degrees, thereby realizing the replacement of the hook point 340 of the clamping cover 324 and the clamping end 34 in the clamping port 312. The clamping cover 324 clamps the material in the bayonet 311 and then puts it into the next bayonet 311 to complete the loading of the material. The setting of the hook point 340 limits the material to avoid deviation. The structure is simple and can be effectively used in a variety of environments.

[0047] It should be noted that, as the degree of socketing between the sleeve 341 and the sleeve 344 increases, the drive bar 345 is first squeezed against the oblique lower end of the operating block 349, so that the drive bar 345 slides along the operating block 349 and smoothly slides to the lower end of the oblique edge 343, thereby realizing the rotation of the sleeve 344. After rotating to the limit, the operating block 349 will be squeezed, and the operating block 349 will be forced to produce local rotation. Subsequently, the sleeve 344 is reset under the action of the reset spring 346, and the operating block 349 is also reset under the action of the torsion spring, so that the drive bar 345 can be squeezed against the oblique lower end of the operating block 349 again, ensuring that the drive bar 345 moves along the oblique edge 343, thereby realizing the replacement of the hook point 340 of the clamping cover 324 and the clamping end 34 in the clamping mouth 312.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
