Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, specifically to a hole-opening device for a mulching machine. Background Technology
[0002] In agricultural production, mulching technology is widely used for heat preservation, moisture retention, and weed control, thereby promoting crop growth and increasing yield. After mulching, neat holes need to be made in the film for sowing or transplanting seedlings. Traditional methods mostly rely on manual cutting or punching of holes in the film, which is inefficient, labor-intensive, and makes it difficult to maintain consistent spacing and depth of the holes, affecting the uniformity of subsequent crop growth.
[0003] Existing mulching machine perforation equipment typically includes a frame, a perforating roller fixed on the frame, and a soil covering disc set on both sides of the roller. During operation, the roller rotates as the equipment moves forward, driving the perforating needle to periodically puncture the mulch film to complete the perforation.
[0004] The following shortcomings exist in the use of this type of device: the position of the perforating needle on the roller is usually fixed and cannot be flexibly adjusted according to the planting spacing requirements of different crops, making it difficult to meet various needs; the perforating needle is mostly rigidly connected, and when it encounters hard objects such as stones, the needle body is prone to bending or breaking, affecting the perforation effect and increasing the cost of maintenance and replacement; the equipment lacks an adjustable-angle soil covering mechanism that cooperates with the perforation mechanism, affecting the efficiency and covering effect of soil covering after perforation. Summary of the Invention

[0026] Two sets of second-level support rods 12 are located between two sets of third-level support rods 15. The front ends of both sets of second-level support rods 12 have threaded channels that mate with first-level bolts 13. A roller assembly 3 is fixedly installed between the two sets of second-level support rods 12 via first-level bolts 13. Washers 14 are located between first-level bolts 13 and second-level support rods 12. The front ends of both sets of third-level support rods 15 have channels that mate with limiting blocks 21 and connecting blocks 22. The top of the channels on the two sets of third-level support rods 15... The end has a square groove that mates with the locking block 16. The size of the locking block 16 is larger than that of the limiting locking block 21. The limiting locking block 21 has a groove that mates with the gear locking block 18. The size of the connecting block 22 is smaller than that of the limiting locking block 21. The fixed base 23 has a channel that mates with the connecting rod 24. The connecting rod 24 has a first bolt 13 inside. A washer 14 is placed between the first bolt 13 and the connecting rod 24.

[0027] In this utility model, the working steps of the device are as follows: By grasping and lifting the handle 17, the locking block 16 and the gear locking block 18 are driven upward in the square groove, thereby disengaging the gear locking block 18 from the limiting locking block 21 in the disc assembly 2. The disc assembly 2 can then rotate through the locking structure of the limiting locking block 21, the connecting block 22, and the third support rod 15. When the rotation reaches a suitable angle, the handle 17 is grasped to insert the locking block 16 and the gear locking block 18 back into the third support rod 15 and the limiting locking block 21, so that the gear locking block 18 locks the limiting locking block 21. The gear locking block 18 is fixed by the structure of the locking block 16 and cannot rotate, thereby fixing the disc assembly 2. This structure allows the equipment to flexibly adapt to different operational needs, ensuring the effectiveness and stability of the soil covering operation.
[0028] Please see Figures 2 to 4 Based on the same concept as the above embodiments, this embodiment also proposes: the inner sides of both sets of rotating shafts 38 are fixedly connected with limiting round blocks 39, the roller 31 is cylindrical, the outer side of the roller 31 is laterally provided with strip-shaped holes that cooperate with twelve sets of punching needles 35, the top and bottom of the inner side of the roller 31 are provided with threaded holes that cooperate with two sets of No. 2 bolts 36, the inner side of the No. 1 punching ring 32 is provided with grooves that cooperate with twelve sets of springs 34, the top and bottom of the inner side of the No. 2 punching ring 33 is provided with threaded grooves that cooperate with two sets of No. 2 bolts 36, the inner side of the No. 2 punching ring 33 is provided with holes that cooperate with twelve sets of springs 34, the size of the punching needle 35 is equal to the size of the spring 34, the inner side of the shaft head 37 is provided with holes that cooperate with the rotating shaft 38, and the inner side of the rotating shaft 38 is provided with threaded grooves that cooperate with the washer 14.
[0029] In the above embodiment, the roller assembly 3 is mounted between the two sets of second support rods 12 of the base assembly 1 via rotating shafts 38 on both sides. The first bolt 13 is rotated into the threaded groove inside the rotating shaft 38 for fastening. A washer 14 is placed between the first bolt 13 and the rotating shaft 38 to make the threaded connection more secure. When the multiple sets of second bolts 36 are rotated out, the first and second perforating rings 32 and 33 inside the roller 31 can slide laterally, thereby changing the distribution of the four perforation units on the roller 31. The adjustable drilling spacing allows the equipment to rotate as it moves forward, causing the drum 31 to rotate. The four drilling units on the drum rotate accordingly, and the drilling needles 35 periodically penetrate the soil to create holes. When a drilling needle 35 encounters a hard object during penetration, the impact force compresses the spring 34 on its outer side, causing the drilling needle 35 to retract into the first drilling ring 32, thus buffering the impact and preventing damage. After passing the hard object, the rebound force of the spring 34 resets the drilling needle 35. This structure effectively reduces the maintenance frequency and ensures the continuity of operation.
