Description

Technical Field

[0001] This utility model relates to the field of plastic film perforation technology, specifically a plastic film breaking device for potato planting. Background Technology

[0002] A potato planting film-breaking device is an agricultural machinery component or equipment specifically used to break the plastic film (usually plastic film) covering the surface of farmland during potato planting. Main types include press-type film breakers, roller-type film breakers, toothed rake-type film breakers, and vibrating needle-type film breakers. When using a press-type film breaker, hold the pressing rod and place the support ring at the lower end of the film breaker on the surface of the film. Move the pressing rod downwards, causing the pressure cylinder below to move down along the hole in the middle of the support ring, opening the film. Then release the pressing rod; the springs at both ends of the pressure cylinder will cause it to move upwards.

[0003] Traditional press-type film-breaking machines rely entirely on the operator's feel and experience to estimate the spacing between two punches, which can easily lead to hole spacing deviations and affect the growth of potato seedlings. Therefore, there is a need to provide a film-breaking device for potato planting to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a film-breaking device for potato planting, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a film-breaking device for potato planting, comprising:

[0006] A plastic film perforator, comprising a support ring, a support column, and a pressure cylinder. The lower end of the support column is welded to two symmetrical ends above the support ring. The two sides of the pressure cylinder are movably connected to the support column via sliders, and the pressure cylinder is movably connected to the inner side of the support ring.

[0007] The positioning component includes a support plate, an adjustable connecting rod, and a scale line. The support plate is fixed to the upper end of the support ring and located on the side of the middle support column. One end of the adjustable connecting rod is fixed to the upper end of the support plate, and the scale line is engraved on the upper end of the adjustable connecting rod.

[0008] Furthermore, the positioning component also includes an opening, a threaded hole, and a locking rod. The opening is located at the upper end of the support plate, and one end of the adjustable connecting rod is inserted into the opening. The threaded hole is located at the middle of the top of the support plate, and the locking rod is screwed into the threaded hole.

[0009] Furthermore, the positioning component also includes an indicator plate, which is fixed below the other end of the adjustable connecting rod away from the support plate.

[0010] Furthermore, the length of the indicator plate is less than the length of the support plate, and its lower end is higher than the upper surface of the support ring.

[0011] Furthermore, the mulch film punch also includes a movable rod, which is welded to the side of the pressure cylinder.

[0012] Furthermore, it also includes a balancing assembly, which includes a screw and a counterweight. The lower end of the screw is welded to the support ring at the other end away from the support plate and is located on the side of another support column. The counterweight is fixed to the screw.

[0013] Furthermore, the balancing assembly also includes a through hole, which is formed in the middle of the counterweight, and the counterweight is sleeved on the screw through the through hole and fastened with a nut.

[0014] This utility model has the following beneficial effects:

[0015] This invention, through a positioning component, allows one end of an adjustable connecting rod to be inserted into an opening on a support plate. The locking rod in the threaded hole is then tightened. The length of the adjustable connecting rod is observed through the scale lines and adjusted to a suitable position. In use, the support ring is placed at the initial perforation point of the mulch film, the pressure rod is pressed, causing the movable rod to move downwards, which in turn moves the pressure cylinder downwards to perforate the mulch film below. The mulch film perforator is then lifted and moved to the next location. When the indicator plate moves to the previously perforated hole, the support ring is lowered to continue the perforation operation. This design ensures that potato seedlings receive uniform growth space, avoids a decrease in the mulch film's heat retention performance due to hole spacing deviations, and improves perforation efficiency.

[0026] Please see Figure 1-4 As shown, this utility model is a film-breaking device for potato planting, comprising:

[0027] The mulch film puncher includes a support ring 10, a support column 11, and a pressure cylinder 13. The lower end of the support column 11 is welded to the two symmetrical ends above the support ring 10. The two sides of the pressure cylinder 13 are movably connected to the support column 11 via sliders, and the pressure cylinder 13 is movably connected to the inside of the support ring 10.

[0028] The plastic film punch also includes a movable rod 12, which is welded to the side of the pressure cylinder 13;

[0029] The support ring 10 provides support and limit function, the support column 11 provides guidance function, and the lower end is sleeved with a spring, which helps the pressure cylinder 13 to return to its original position. The movable rod 12 is connected to the pressure cylinder 13, and a pressure rod is installed at the upper end, which makes it easy for operators to press the pressure cylinder 13. After the pressure cylinder 13 is pressed down, it can punch holes in the mulch film.

[0030] The positioning component includes a support plate 20, an adjustable connecting rod 24, and a scale line 25. The support plate 20 is fixed to the upper end of the support ring 10 and is located on the side of the middle support column 11. One end of the adjustable connecting rod 24 is fixed to the upper end of the support plate 20, and the scale line 25 is engraved on the upper end of the adjustable connecting rod 24.

[0031] The positioning assembly also includes an opening 21, a threaded hole 22 and a locking rod 23. The opening 21 is opened at the upper end of the support plate 20, and one end of the adjustable connecting rod 24 is inserted into the opening 21. The threaded hole 22 is opened at the middle of the top of the support plate 20, and the locking rod 23 is screwed into the threaded hole 22.

[0032] The positioning assembly also includes an indicator plate 26, which is fixed below the other end of the adjustable connecting rod 24 away from the support plate 20;

[0033] The length of the indicator plate 26 is less than the length of the support plate 20, and its lower end is higher than the upper surface of the support ring 10;

[0034] The support plate 20 provides support, the opening 21 provides connection, the threaded hole 22 and the locking rod 23 are used to lock the adjustable connecting rod 24. The adjustable connecting rod 24 adjusts its length in conjunction with the scale line 25 and provides positioning. The indicator plate 26 provides positioning.

[0035] Working principle:

[0036] Insert one end of the adjustable connecting rod 24 into the opening 21 on the support plate 20, tighten the locking rod 23 in the threaded hole 22, observe the length of the adjustable connecting rod 24 through the scale line 25 and adjust it to a suitable position. When in use, place the support ring 10 at the initial drilling position of the mulch film, press the pressure rod to drive the movable rod 12 down, and then drive the pressure cylinder 13 down to drill holes in the mulch film below. Then lift the mulch film puncher and move it to the next position. When the indicator plate 26 moves to the previous drilled hole, place the support ring 10 down and continue the drilling operation.

[0037] This step ensures that potato seedlings have a uniform growing space, avoids a decrease in the heat retention performance of the mulch film due to hole spacing deviation, and can improve drilling efficiency.
