[0068] By rotating the second threaded rod 306, the second sliders 303 arranged on both sides of the fixed block 307 are driven to move toward the middle at the same time. The simultaneous movement of the second sliders 303 toward the middle will drive one end of the pushing rod 304 to move toward the middle, and the other end of the pushing rod 304 will push the lifting plate 204 outward to move along the fixed column 305, thereby adjusting the distance between the punching cones 205 on the punching assemblies 2 on both sides of the frame 1.

[0069] As a further optimization scheme of the present invention, Figure 6As shown, the punching assembly 2 also includes an adjustment assembly 9, which includes a second guide rod 904, a third threaded rod 903, baffles 901 installed at both ends of the lifting plate 204, and a support block 902 installed in the middle of the lifting plate 204. Strip through holes 207 are opened on both sides of the center line of the lifting plate 204. The arrangement of the strip through holes 207 facilitates the adjustment of the punching cone 205 and the reaming mechanism 8. The punching cone 205 and the sliding plate 8013 are respectively slidably matched with the strip through holes 207 located on both sides of the center line of the lifting plate 204.

The slide plates 8020 arranged on both sides of the side plate 8018 are respectively connected with the second guide rod 904 and the third threaded rod 903. The moving block on the punching cone 205 and the slide plate 8020 on the side plate 8018 are both threadedly matched with the third threaded rod 903.

[0070] By rotating the third threaded rod 903, the punching cone 205 and the reaming mechanism 8 are driven to move toward the middle or to both sides at the same time, ensuring that the reaming mechanism 8 can accurately fall into the hole punched by the front punching cone 205, thereby achieving the purpose of expanding the hole under the action of the reaming mechanism 8.

[0073] Example 1

[0074] When working, the device is pushed to the specified position, and the gasoline engine 4 is turned on to drive the moving wheel 5 to move. The moving wheel 5 rotates to drive the frame 1 to move, and can also drive the first pulley 601 to rotate. The first pulley 601 drives the second pulley 603 or the third pulley 604 to rotate through the belt 602. The rotation of the second pulley 603 or the third pulley 604 drives the fixed shaft 206 on one of the rotating rods 203 to rotate. The rotation of the fixed shaft 206 drives one of the rotating rods 203 to rotate. The simultaneous rotation of the two parallelly arranged rotations can drive the lifting plate 204 to move up and down. The up and down movement of the lifting plate 204 drives the drilling cone 205 to move up and down, thereby achieving the purpose of drilling holes in the land after turning over.

[0075] Example 2

[0076] When the staff needs to adjust the hole spacing of the punching holes, the belt 602 is adjusted on the second pulley 603 or the third pulley 604. After the adjustment is completed, the belt 602 is ensured to be in a stretched state to ensure the normal operation of the belt 602. The handle 705 is turned to drive the first threaded rod 706 to rotate. The rotation of the first threaded rod 706 drives the first slider 703 to move along the strip hole 702. The movement of the first slider 703 will drive the lifting pulley 704 to move. The movement of the lifting pulley 704 can achieve the purpose of pulling the belt 602 to tighten the belt 602.

[0077] Example 3

[0078] A hole expanding mechanism 8 is installed on the other end of the lifting plate 204. When the lifting plate 204 descends to the point where the lifting plate 8028 is located in the punched hole, the hole expanding mechanism 8 is continuously driven downward, and the lifting plate 8028 moves toward the side close to the sliding plate 8013. The movement of the lifting plate 8028 drives the vertical plate 8022 to move. The movement of the vertical plate 8022 drives the first rotating arm 805 and the second rotating arm 806 to rotate around the hinge of the first rotating arm 805 and the second rotating arm 806. The rotation of the first rotating arm 805 and the second rotating arm 806 simultaneously pushes the pushing plates 804 arranged on both sides of the lifting frame 802 outward, thereby achieving the purpose of expanding the punched hole. During the movement, the guide rod 8025 will slide along the mounting block 8016, and the second spring 8021 will be compressed while the guide rod 8025 slides. When the lifting plate 204 moves upward, the second spring 8021 will reset and drive the lifting plate 8028 to move downward. The lifting plate 8028 will move downward and drive the vertical plate 8022 to move downward. The vertical plate 8022 will move downward and drive the sliding column 8010 to move downward. The sliding column 8010 will move downward and drive the first rotating arm 805 and the second rotating arm 806 to rotate around the hinge of the first rotating arm 805 and the second rotating arm 806, thereby driving the pushing plates 804 arranged on both sides of the lifting frame 802 to move toward the middle, so as to facilitate the hole expansion again.

[0079] Example 4

[0080] In order to ensure that the row spacing of the punching holes can be controlled as needed, the staff rotates the second threaded rod 306, and the second threaded rod 306 rotates to drive the second sliders 303 set on both sides of the fixed block 307 to move toward the middle at the same time. The second sliders 303 move toward the middle at the same time, which will drive one end of the push rod 304 to move toward the middle, and the other end of the push rod 304 will push the lifting plate 204 outward to move along the fixed column 305, thereby achieving the purpose of adjusting the distance between the punching cones 205 on the punching components 2 on both sides of the frame 1. When adjusting the device, only the adjustment member 3 on one side can be adjusted, or the adjustment members 3 on both sides can be adjusted at the same time, which greatly improves the flexibility of the device.

[0081] Example 5

[0082] In order to ensure that the punching cone 205 and the reaming mechanism 8 can work normally, the reaming mechanism 8 at one end of the lifting plate 204 can normally extend into the hole punched by the punching cone 205, and the staff rotates the third threaded rod 903. Since the thread options at both ends of the center line of the third threaded rod 903 are opposite, the rotation of the third threaded rod 903 will drive the slide plate 8020 and the moving block to move inward or outward at the same time. The movement of the slide block and the moving block will drive the reaming mechanism 8 and the punching cone 205 to move inward or outward at the same time, thereby achieving the purpose of adjusting the punching cone 205 and the reaming mechanism 8, ensuring that the reaming mechanism 8 can normally extend into the hole punched by the punching cone 205, thereby ensuring the normal operation of the reaming mechanism 8.
