[0030] Example 1

[0031] like Figure 1-Figure 5 As shown:

[0032] A ground film hole-making device comprises a frame 8, the frame 8 is a concave structure, and a traction connection mechanism connected to a towing main machine is installed on the front side surface of the frame 8.

[0033] The traction connection mechanism includes a screw rod 2 and two fixed plates 3. The two fixed plates 3 are arranged up and down and are installed on the frame 8. The screw rod 2 is vertically arranged. The top end of the screw rod 2 is connected to the crank 1. The bottom end of the screw rod 2 is installed on the fixed plate 3 located below. The fixed plate 3 located above is arranged below the crank 1. The two fixed plates 3 are rotatably connected to the screw rod 2 through bearings.

[0034] A lifting plate 4 screwed to the screw rod 2 is provided between the two fixing plates 3 , and a towing ring 5 is installed on the lifting plate 4 .

[0035] The lifting plate 4 is square in shape as a whole, one side of which is close to the surface of the vehicle frame 8, and the front part of the lifting plate 4 is connected with the towing ring 5 by threaded connection.

[0036] The crank 1 drives the screw rod 2 to rotate and control the lifting plate 4 to rise and fall between the two fixed plates 3. The height adjustment of the lifting plate 4 drives the height adjustment of the towing ring 5, thereby realizing the relative adjustment of the height of the towing main machine and the hole opening operation position, and also helps to adapt to the towing main machine with different towing connection heights. The two fixed plates 3 play a limiting role.

[0037] A hole-making mechanism 6 for making a hole in contact with the ground film is arranged in the middle of the frame 8 , and a gearbox 7 is fixedly mounted inside the frame 8 , and the gearbox 7 has a built-in driving motor for driving the hole-making mechanism 6 to rotate.

[0038] like Figure 2 As shown, the hole opening mechanism 6 includes a slide rail 6-1 and a drive shaft 6-2 arranged in parallel, both ends of the slide rail 6-1 are fixedly mounted on the frame 8, one end of the drive shaft 6-2 is transmission-connected to the gearbox 7, and the other end of the drive shaft 6-2 is rotationally connected to the frame 8.

[0039] like Figure 2 and Figure 3 As shown, the drive shaft 6-2 includes a shaft body 6-21, and a gear 6-22 is provided at one end of the shaft body 6-21 close to the gearbox 7. The shaft body 6-21 is transmission-connected to the gearbox 7 via the gear 6-22, and a connecting key 6-23 arranged axially along the shaft body 6-21 is installed on the outer peripheral surface of the shaft body 6-21.

[0040] A rolling hole-opening mechanism 6-4 that slides along the axis of the slide rail 6-1 is installed on the slide rail 6-1, and a transmission component 6-6 that slides synchronously with the rolling hole-opening mechanism 6-4 along the axis of the drive shaft 6-2 is installed on the drive shaft 6-2.

[0041] The rolling hole opening mechanism 6-4 and the transmission assembly 6-6 are connected and slid synchronously through the connecting plate 6-5, and the rolling hole opening mechanism 6-4 and the transmission assembly 6-6 are connected and driven by the transmission belt 6-3.

[0042] like Figure 4 As shown, the rolling hole opening mechanism 6-4 includes a main shaft 6-44, a rolling body 6-42 is sleeved on the outside of the main shaft 6-44, an electric slip ring is installed between the rolling body 6-42 and the main shaft 6-44, the electric slip ring is rotationally connected to the main shaft 6-44, and the electric slip ring rotates synchronously with the rolling body 6-42.

[0043] A driven wheel 6-41 for driving the rolling body 6-42 to rotate is sleeved on the main shaft 6-44. The driven wheel 6-41 is coaxially arranged with the rolling body 6-42 and fixedly connected. The driven wheel 6-41 is rotationally connected to the main shaft 6-44.

[0044] Six opening heads 6-43 are evenly arranged on the outer circumference of the rolling body 6-42. The ends of the opening heads 6-43 are provided with electric heating elements connected to the energized slip rings. The electric heating elements in this embodiment are annular heating wires.

[0045] like Figure 5 As shown, the transmission assembly 6-6 includes a transmission body 6-62, which is sleeved on the drive shaft 6-2 and slidably connected to the drive shaft 6-2. A key slot cooperating with the connecting key 6-23 is provided on the inner wall of the through hole of the transmission body 6-62. A transmission wheel 6-61 and a connecting bearing 6-63 are installed on the transmission body 6-62. The transmission wheel 6-61 rotates synchronously with the transmission body 6-62, and the transmission body 6-62 is connected to the inner ring of the connecting bearing 6-63.

[0046] like Figure 2-Figure 5 As shown, the driving wheel 6-61 is connected to the driven wheel 6-41 through a transmission belt 6-3, the connecting bearing 6-63 is connected to the main shaft 6-44 of the rolling hole opening mechanism 6-4 through a connecting plate 6-5, and the connecting plate 6-5 is connected to the outer ring of the connecting bearing 6-63.

[0047] like Figure 1 As shown, a wheel 9 is installed on the side of the frame 8, and the wheel 9 is rotatably connected to the outer side of the frame 8 through a hoop, a rotating shaft and a rotating bearing.

[0048] This device uses an energized slip ring to supply power to the electric heating element on the hole punching head 6-43, so that the end of the hole punching head 6-43 can generate a high temperature that can melt through the ground film; at the same time, the drive shaft 6-2 is driven to rotate by means of the drive motor and the gearbox 7, and the drive shaft 6-2 drives the transmission component 6-6 and the transmission belt 6-3 in conjunction, so that the rolling hole punching component 6-4 can finally rotate at a uniform speed. Therefore, driven by the towing main machine, the equipment can continuously perform hole punching operations on the ground film, which greatly improves the working efficiency.

[0049] When the utility model is in use, the specific operations are as follows:

[0050] Before use, the device is mounted on the rear of the towing host through the towing ring 5, and connected to the corresponding line equipment and can be put into use.

[0051] When in use, the towing hook of the towing main unit is first connected to the towing ring 5, and the towing hook and the towing ring 5 are movably connected, and the towing main unit drags the device to the work site.

[0052] Shake the crank 1 to rotate the screw 2, and the rotating screw 2 enables the lifting plate 4 to descend along the thread. Since the towing ring 5 is restricted by the towing hook of the main machine, the height of the descending lifting plate 4 remains unchanged, and the side of the frame 8 where the crank 1 is installed will rise, so that the rear opening mechanism 6 can be lowered to the working height. At this time, the transmission ratio of the internal gear of the gearbox 7 is controlled as needed, and the rotation speed of the rolling opening component 6-4 is determined, and the equipment can start opening holes.

[0053] The internal gear of the gearbox 7 drives the gear 6-22, the gear 6-22 drives the shaft 6-21 to rotate, the connecting key 6-23 of the shaft 6-21 drives the transmission body 6-62 to rotate, the transmission body 6-62 drives the rolling body 6-42 to rotate with the axis of the main shaft 6-44 as the rotation center through the transmission belt 6-3, and the external power supply is transmitted to the main shaft 6-44 through the energized slip ring, so that the electric heating element on the hole opening head 6-43 can be heated normally, so that the hole opening head 6-43 can perform the hole opening operation continuously at a uniform speed.

[0054] Among them, the rolling hole opening component 6-4 and the transmission component 6-6 are connected by a connecting plate 6-5, so that the rolling hole opening component 6-4 and the transmission component 6-6 become a whole, which is convenient for the staff to move it synchronously to the left or right along the slide rail 6-1 and the drive shaft 6-2 to more accurately determine the hole opening point.

[0055] Since the main shaft 6-44 itself does not rotate, its main function is to provide a mounting base and stable support for the rolling body 6-42. Therefore, the main shaft 6-44 can be rigidly connected to the connecting plate 6-5, and the transmission assembly 6-6 itself is used to drive the rolling body 6-42 to rotate at a certain speed. Therefore, the transmission body 6-62 needs a rotatable connecting bearing 6-63 to fix the connecting plate 6-5 to prevent it from getting stuck.

[0056] In summary, in this device, the gear 6-22 is driven by the gearbox 7, the gear 6-22 drives the shaft 6-21 to rotate, the shaft 6-21 is embedded and connected through the connecting key 6-23 to drive the transmission body 6-62 to rotate, the transmission body 6-62 drives the rolling body 6-42 to rotate around the main shaft 6-44 through the transmission belt 6-3, and the external power supply is transmitted to the electric heating element at the end of the hole opening head 6-43 through the energized slip ring, which can be heated normally, so that the hole opening head 6-43 can perform the hole opening operation at a uniform and continuous speed, effectively reducing labor intensity, improving film breaking efficiency, and realizing mechanized film breaking operation.

[0057] Example 2

[0058] The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 6As shown, the rotating shaft on the wheel 9 extends to the inner side of the frame 8 and a driving disc is installed at the end. The driving disc is connected to the gearbox 7 through a belt 10. The rolling opening assembly 6-4 is driven to rotate by the power when the wheel 9 rolls. The driving force of the built-in driving motor of the gearbox 7 is replaced by the driving force of the wheel 9 when it rolls, thereby reducing the weight of the overall equipment and reducing the power consumption of the device.

[0059] Example 3

[0060] The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 7 As shown, in this embodiment, a ball screw 6-7 is used instead of the slide rail 6-1, and the main shaft 6-44 of Example 1 is replaced by the sliding block of the ball screw 6-7. The ball screw 6-7 is rotatably connected to the frame 8. One end of the ball screw 6-7 can be connected to a rotating motor that drives the ball screw 6-7 to rotate, or it can be connected to the gearbox 7 using a gear transmission mechanism.

[0061] The ball screw 6-7 is used to realize the electronically controlled automation of the sliding movement of the hole opening mechanism 6, thereby improving the precision adjustment of the hole opening position.

[0062] Example 4

[0063] In order to further optimize the working efficiency of the device and reduce the weight of the device as much as possible, the frame 8 is made of welded steel pipes.

[0064] In order to make the main shaft 6-44 and the transmission body 6-62 move more smoothly when moving left and right, grooves for installing balls are provided on the inner sides of the main shaft 6-44 and the transmission body 6-62 that contact the slide rail 6-1 and the drive shaft 6-2.

[0065] In order to prevent unnecessary displacement of the main shaft 6-44 and the transmission body 6-62, friction blocks driven by springs are provided at both ends of the main shaft 6-44 and the transmission body 6-62.

[0066] In order to improve the hole-opening efficiency of the device and realize the simultaneous opening of multiple parallel holes on the ground film, the hole-opening mechanism 6 can be equipped with multiple groups of rolling hole-opening components 6-4 and transmission components 6-6.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
