The length of the limit block 20 is less than the distance between the spring 7 and the inner top of the slide groove 4. The limit block 20 is convenient for limiting the slide block 5, so that the downward extension length of the inner pressure arm 8 and the outer pressure arm 9 is limited, and the bottom of the cylindrical cover 11 is extended out of the bottom of the drill bit 3 to protect the drill bit when it is not working.

[0043] Furthermore, if Figure 5 As shown, the middle portion of the inner pressure arm 8 is provided as an intermediate plate 21 to facilitate cooperation with the outer pressure arm 9 .

[0044] Furthermore, if Figure 5 As shown, a plate opening 22 is provided on the outer pressure arm 9, the thickness of the middle plate 21 is smaller than that of the plate opening 22, the middle plate 21 passes through the plate opening 22, and rod openings 23 are provided on the outer pressure arm 9 and the middle plate 21.

[0048] Preferably, if Figure 3 As shown, the connecting rod 16 is in an inverted Y shape, which is convenient for improving the stability of the brush 17.

[0049] A specific application of the present application is as follows: the present utility model is suitable for punching and drilling holes in counterweights of agricultural machinery. When in use, the device is installed on an external lifting device (not shown) through a mounting hole (not shown) on a mounting plate 1, so that the drill bit 3 is located above the position to be drilled. When not working, due to the elastic contraction tension of the spring 7, the two groups of slide blocks 5 are stuck on the two groups of limit blocks 20, and the bottom end of the cylindrical cover 11 is located below the bottom end of the drill bit 3 through the inner pressure arm 8 and the outer pressure arm 9. When working, the lifting device drives the device to move downward, and the cylindrical cover 11 is first pressed above the counterweight to be drilled, and continues to move downward. Due to the action of the inner pressure arm 8 and the outer pressure arm 9, the spring 7 is stretched, and the two groups of slide blocks 5 slide in opposite directions in the slide groove 4. The drill bit 3 contacts the counterweight behind the cylindrical cover 11, and then the first motor 2 is started to drive the drill bit 3 to rotate to drill the counterweight. The drilling debris falls into the cylindrical cover 11. When the drilling is completed, the first motor 2 is turned off, and the second motor 18 is started to drive the bevel gear 19 to rotate. The bevel gear 19 meshes with the bevel gear ring 15 to drive the bevel gear ring 15 to rotate. The hanging slide block 14 slides in the annular slide groove 13 to guide the bevel gear ring 15. The bevel gear ring 15 drives the brush 17 to move in a left circle in the cylindrical cover 11 through the connecting rod 16. The brush 17 sweeps the debris in the cylindrical cover 11 into a pile for subsequent collection. Then the second motor 18 is turned off, and the lifting equipment moves the device upward. The drill bit 3 is separated from the counterweight. Due to the elastic force of the spring 7, the two groups of slide blocks 5 are driven to move closer to each other and are stuck on the limit block 20. The inner pressure arm 8 and the outer pressure arm 9 move in a scissors-like closing shape, pushing the cylindrical cover 11 downward, so that the bottom of the cylindrical cover 11 covers the drill bit 3 to protect the drill bit 3.

[0050] All electrical components appearing in this article are electrically connected to an external power source.
