[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When drilling holes, the present invention has several heating discs arranged on the rotating cylinder cyclically drill holes on the ground film. When drilling holes, the heating discs press down the ground film, and the heating discs are squeezed by the ground and shrink into the first gear cylinder and the second gear cylinder. At the same time, the first gear cylinder and the second gear cylinder cut off the film body connected to the drilling position of the ground film. As the rotating cylinder rotates, the heating discs in the first row pop out from the first gear cylinder and the second gear cylinder, and then the heating discs in the second row drill holes at another position on the ground film, and the spacing of the holes drilled each time is the same, so as to achieve the purpose of facilitating automatic drilling.

[0022] 2. When the hole spacing of the heating plate needs to be adjusted, the hand wheel is manually rotated to drive the movable sleeve to rotate. After the movable sleeve rotates, the sleeve is driven to pull back linearly. After the sleeve is pulled back, the pressure columns at both ends will withdraw from the end of the push rod. At this time, the first spring will drive the push rod to reset and pull the second gear cylinder back. In this way, when the rotating cylinder rotates, the second gear cylinder will not contact the ground film, but can only open the holes through the first gear cylinder, which indirectly increases the spacing between each row of circular holes, thereby achieving the purpose of facilitating the adjustment of the hole spacing;

[0023] 3. In the present invention, when the heating disk is squeezed by the ground and retracted into the first gear cylinder and the second gear cylinder, the connecting plates arranged horizontally between the multiple heating disks will drive a row of heating disks to move synchronously, and the connecting plates will be pressed against the surface of the ground film, so as to prevent the ground film from being compressed and folded when the hole is opened. At the same time, after the heating disk is ejected, the connecting plates will continue to press the ground film to prevent the ground film from sticking to the tooth blocks of the first gear cylinder or the second gear cylinder.

A second gear 30 is fixedly installed on the left side of the connecting shaft 2 between the two driving wheels 3, and a first gear 31 is fixedly installed on the right side of the output shaft of the motor 6 near the first pulley 11. The first gear 31 and the second gear 30 are movably connected through a toothed belt. A controller 36 is fixedly installed on the top of the side of the platform 5 away from the motor 6, and the controller 36 is electrically connected to the motor 6. When drilling a hole, the motor 6 is started, and after the motor 6 is started, the first gear 31 is controlled to rotate. After the first gear 31 rotates, the second gear 30 on one side of the connecting shaft 2 is driven to rotate through the toothed belt. After the second gear 30 rotates, the connecting shaft 2 between the two driving wheels 3 is driven to rotate synchronously. When the connecting shaft 2 rotates, the driving wheels 3 at both ends are driven to rotate, and then the frame 1 is controlled to move on the ground in cooperation with the two auxiliary wheels 4, so that in the drilling type, no handheld device is required to move;

[0034] like Figure 1 , Figure 2 and Figure 7 As shown, a platform 5 is fixedly installed in the middle of one side of the frame 1 close to the driving wheel 3, a motor 6 is fixedly installed on one side of the top of the platform 5, a rotating cylinder 8 is movably installed on the side of the frame 1 away from the platform 5 through a transmission shaft 7, a plurality of first gear cylinders 9 are fixedly installed on the four sides of the outside of the rotating cylinder 8, a plurality of second gear cylinders 10 are movably installed between the rotating cylinder 8 close to the plurality of first gear cylinders 9, a heating disk 21 is movably installed on the inner sides of the first gear cylinder 9 and the second gear cylinder 10, a second spring 22 is arranged on the side of the first gear cylinder 9 and the second gear cylinder 10 away from the heating disk 21, one end of the second spring 22 is fixedly connected to the heating disk 21, and the outside of the side of the heating disk 21 close to the second spring 22 is movably connected to the first gear cylinder 9 and the second gear cylinder 10 through an anti-slip ring 23, the number of the first gear cylinder 9 and the second gear cylinder 10 is equal, a first pulley 11 is fixedly installed on the output shaft end of the motor 6, and a first gear cylinder 12 is fixedly installed on the outside of the end of the transmission shaft 7 close to the first pulley 11 The second pulley 12 is movably connected with the first pulley 11 through a belt. When the motor 6 is started, the first pulley 11 is driven to rotate. After the first pulley 11 rotates, the second pulley 12 at one end of the transmission shaft 7 is driven to rotate synchronously through the belt. After the second pulley 12 rotates, it drives the transmission shaft 7 to rotate. When the transmission shaft 7 rotates, the rotating cylinder 8 is controlled to rotate synchronously, and a plurality of heating discs 21 arranged on the rotating cylinder 8 will cyclically open holes on the ground film. When opening holes, the heating disc 21 will press down the ground film. After being squeezed by the ground, the heating disc 21 shrinks into the first gear cylinder 9 and the second gear cylinder 10. At the same time, the first gear cylinder 9 and the second gear cylinder 10 cut off the film body connected to the opening position of the ground film. With the rotation of the rotating cylinder 8, the heating discs 21 of the first row will pop out from the first gear cylinder 9 and the second gear cylinder 10, and then the heating discs 21 of the second row will open holes at another position on the ground film, and the spacing of the holes opened each time is the same, so as to achieve the purpose of facilitating automatic opening of holes.

[0035] like Figure 2 , Figure 5 and Figure 6As shown, a shaft frame 13 is fixedly installed on the outside of the end of the second pulley 12 away from the transmission shaft 7, a movable sleeve 14 is movably installed in the middle of the end of the shaft frame 13 away from the second pulley 12, a screw rod 15 is movably installed inside the movable sleeve 14, and a hand wheel 16 is fixedly installed on the outside of the end of the movable sleeve 14 close to the second pulley 12, a sleeve 17 is movably installed on the inner side of the middle of the rotating cylinder 8, and a plurality of pressure columns 18 are arranged at both ends of the sleeve 17, a push rod 20 is arranged on the side of the rotating cylinder 8 away from the pressure column 18 through a first spring 19, and the end of the push rod 20 away from the pressure column 18 is fixedly connected to the second gear cylinder 10, the sleeve 17 is threadedly connected to the screw rod 15, and guide grooves 28 are provided on both sides of the rotating cylinder 8 close to the sleeve 17, and both sides of the sleeve 17 are guided by guides The block 29 is slidably connected to the guide groove 28, and the two sides of the rotating cylinder 8 close to the second gear cylinder 10 are provided with sliding grooves 26. The outside of the two sides of the second gear cylinder 10 are slidably connected to the sliding grooves 26 through sliders 27. When it is necessary to adjust the hole spacing of the heating plate 21, the hand wheel 16 is manually turned, and the hand wheel 16 drives the movable sleeve 14 to rotate. After the movable sleeve 14 rotates, it drives the sleeve 17 to pull back in a straight line. After the sleeve 17 is pulled back, the pressure columns 18 at both ends will withdraw from the end of the push rod 20. At this time, the first spring 19 will drive the push rod 20 to reset and pull the second gear cylinder 10 back. In this way, when the rotating cylinder 8 rotates, the second gear cylinder 10 will not contact the ground film, and can only open holes through the first gear cylinder 9, which indirectly increases the spacing between each row of circular holes, thereby achieving the purpose of facilitating the adjustment of the hole spacing.

[0036] like Figure 7 As shown, a connecting plate 24 is provided between the first gear cylinders 9 and the second gear cylinders 10, and a third spring 25 is provided on one side of the rotating cylinder 8 close to the connecting plate 24. The other end of the third spring 25 is fixedly connected to the connecting plate 24. When the heating disc 21 is squeezed by the ground and retracted into the first gear cylinder 9 and the second gear cylinder 10, the connecting plate 24 arranged horizontally between the plurality of heating discs 21 will drive a row of heating discs 21 to move synchronously, and the connecting plate 24 will be pressed against the surface of the ground film, so that when the hole is opened, the ground film is prevented from being folded due to pressure. At the same time, after the heating disc 21 is ejected, the connecting plate 24 will continue to press the ground film to prevent the ground film from adhering to the tooth blocks of the first gear cylinder 9 or the second gear cylinder 10.

[0037] like Figure 3As shown, a fixing rod 32 is movably installed at the right end of the frame 1 close to the platform 5 through a bearing, a fourth gear 33 is fixedly installed on the outside of the fixing rod 32 close to the motor 6, a third gear 34 is arranged on the outside of the right end of the output shaft of the motor 6 close to the first gear 31, the third gear 34 and the fourth gear 33 are movably connected through a toothed belt, a plurality of scrapers 35 are arranged on the side of the fixing rod 32 close to the heating plate 21, and the scrapers 35 are made of high temperature resistant rubber. When the motor 6 is started, the third gear 34 will also be driven to rotate. When the third gear 34 rotates, it drives the fourth gear 33 to rotate through the toothed belt. When the fourth gear 33 rotates, it drives multiple scrapers 35 to rotate in the same direction as the rotating cylinder 8 through the fixed rod 32. In this way, the heating disk 21 that has been used once will flip up from the right side of the rotating cylinder 8, and the scraper 35 will flip down from the left side of the fixed rod 32, thereby scraping off the melted film remaining on the surface of the heating disk 21. The scraper 35 is made of high temperature resistant material and will not be melted by the heating disk 21. At the same time, it has a certain ductility and will not interfere with the rotation of the heating disk 21.

[0038] Working principle: when drilling a hole, start the motor 6. After the motor 6 is started, the first gear 31 is controlled to rotate. After the first gear 31 rotates, it drives the second gear 30 on one side of the connecting shaft 2 to rotate through the toothed belt. After the second gear 30 rotates, it drives the connecting shaft 2 between the two driving wheels 3 to rotate synchronously. When the connecting shaft 2 rotates, it drives the driving wheels 3 at both ends to rotate, and then cooperates with the two auxiliary wheels 4 to control the frame 1 to move on the ground. When the motor 6 is started, it drives the first pulley 11 to rotate. After the first pulley 11 rotates, it drives the second pulley 12 at one end of the transmission shaft 7 to rotate synchronously through the belt. After the second pulley 12 rotates, it drives the transmission shaft 7 to rotate. When the transmission shaft 7 rotates, the rotating cylinder 8 is controlled to rotate synchronously, and a number of heating disks 21 arranged on the rotating cylinder 8 will circulate to drill holes on the ground film. When drilling holes, the heating disks 21 will press down the ground film, and the heating disks 21 are After being squeezed by the ground, it shrinks and enters the first gear cylinder 9 and the second gear cylinder 10. At the same time, the first gear cylinder 9 and the second gear cylinder 10 cut off the film body connected to the opening position of the ground film. With the rotation of the rotating cylinder 8, the heating discs 21 of the first row will pop out from the first gear cylinder 9 and the second gear cylinder 10, and then the heating discs 21 of the second row will make holes at another position on the ground film, and the spacing of the holes made each time is the same. When the heating discs 21 are squeezed by the ground and retracted into the first gear cylinder 9 and the second gear cylinder 10, the connecting plates 24 arranged horizontally between the multiple heating discs 21 will drive a row of heating discs 21 to move synchronously, and the connecting plates 24 will be pressed on the surface of the ground film. In this way, when making a hole, the ground film is prevented from being compressed and folded. At the same time, after the heating discs 21 are ejected, the connecting plates 24 will continue to press the ground film to prevent the ground film from sticking to the tooth blocks of the first gear cylinder 9 or the second gear cylinder 10.
