Description

Technical Field

[0001] The utility model relates to the field of agricultural films, in particular to an agricultural film punching device. Background Art

[0002] Agricultural film is a general term for plastic film used in agricultural production, which plays a very important role in moisture retention and heat preservation during the sowing period. With the advancement of science and technology, the requirements for agricultural films are getting higher and higher, and various new films continue to emerge. At present, the main material of domestic agricultural mulch is plastic. Ordinary plastic materials are not easy to degrade and accumulate in the soil for a long time, which brings potential harm to the ecological environment. Later, agricultural mulch paper made of plant fiber as the main raw material appeared on the market. The agricultural mulch paper has the advantages of natural degradation and no pollution, but the paper material is much less ductile than the plastic material. Specifically, the plastic material can be manually punched during use, and the holes on the mulch are used to help the agricultural products covered by the mulch to obtain good gas exchange conditions. After the agricultural products break the soil, they can also thrive through the holes in the film. The method of manually punching holes in paper mulch is very likely to cause the mulch to tear and damage as a whole, which greatly affects the use effect of the mulch. For this reason, the application number: CN202123448269.0 discloses a punching device for agricultural mulch paper. It includes a bottom knife roller and a bottom knife guide roller. A cutter is installed on the bottom knife roller. An annular cutting groove cooperating with the cutter is arranged on the bottom knife guide roller. The bottom knife roller and the bottom knife guide roller rotate synchronously and can make the cutter cooperate with the annular cutting groove to cut the ground film paper. At least one sleeve is mounted on the bottom knife guide roller. Each sleeve is arranged with thorns for piercing the ground film paper. During the cutting process, the ground film paper can be pierced by the thorns to form holes. After adopting the above structure, the synchronous rotation of the bottom knife roller and the bottom knife guide roller during the cutting process is utilized to make the thorns pierce the ground film paper evenly to form holes. When the processed agricultural ground film paper is cultivated, the directly formed holes meet good gas exchange, which is suitable for the growth of agricultural products and ensures the use effect of the ground film. Its structural design is simple, the operation is convenient, and it does not require additional power and process, saving production costs.

[0003] However, the above scheme still has certain defects. The inventors have found through research that the thorn-like objects used for punching holes in the agricultural film in the above scheme are fixed on the sleeve.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a device for punching holes in agricultural film, including a rewinder, a perforated roller 1 is arranged on one side between two transport rollers of the rewinder for conveying thin film, one end of the perforated roller 1 is rotatably connected to the rewinder and connected to a driving device to drive it to rotate independently, a plurality of groups of annular evenly distributed extension holes 3 are opened on the outer wall of the circumference of the perforated roller 1, each group of extension holes 3 is evenly distributed in the extension direction of the perforated roller 1, each extension hole 3 is provided with a thorn 4, each group of thorns 4 is connected to a corresponding lifting and adjusting component 2, each lifting and adjusting component 2 includes a lifting plate 201, the lifting plate 201 is slidably connected between the inner walls at both ends of the perforated roller 1, one end of each group of thorns 4 is connected to a side surface of the corresponding lifting plate 201, and each lifting and adjusting component 2 also includes a driving mechanism for driving the lifting plate 201 to independently lift and displace inside the perforated roller 1.

[0022] See also Figure 2 and Figure 3 The driving mechanism is fixedly mounted on the surface of the punching roller 1 at one end away from the end connected to the rewinding machine.

[0023] When in use, the staff can adjust the length of each group of thorns 4 extending out of the punching roller 1 through the driving mechanism, and can operate on the side away from the rewinding machine, thereby improving safety in use and avoiding danger caused by being too close to the rewinding machine.

[0024] Furthermore, a slide groove is provided at one end of the lifting plate 201, and the slide groove is slidably connected to the slide rail 202. The slide rail 202 is fixedly installed on the inner wall of one end of the punching roller 1. The other end of the lifting plate 201 is fixedly connected to a slider 203. The slider 203 is slidably installed in a through slide groove 204 provided on the inner wall of the other end of the punching roller 1. The other end of the slider 203 extends from the through slide groove 204 to the outside of the punching roller 1 and is connected to the driving mechanism.

[0025] The lifting plate 201 is slidably connected to the inner walls of both ends of the punching roller 1 through the slider 203 and the through slide groove 204 as well as the slide groove and the slide rail 202. Driven by the driving mechanism, the corresponding group of thorn-like objects 4 are driven to perform an overall lifting and lowering displacement, thereby controlling the length of the corresponding group of thorn-like objects 4 extending to the outside of the punching roller 1. The diameter of the punching and the longitudinal spacing of the punching can be adjusted as needed to reduce limitations in use.

[0026] Furthermore, the driving mechanism includes a connecting plate 205, which is fixedly connected to the corresponding slider 203. A threaded hole is formed through the surface of the connecting plate 205, and an adjusting screw 206 is threadedly connected in the threaded hole. One end of the adjusting screw 206 is rotatably mounted on the surface of one side of the first mounting plate 207, and the other end of the adjusting screw 206 is rotatably mounted in a through hole formed on the surface of one side of the second mounting plate 208. The first mounting plate 207 and the second mounting plate 208 are both fixedly connected to the surface of one end of the punching roller 1.

[0027] When the adjusting screw 206 is rotated, since the connecting plate 205 is threadedly connected to the adjusting screw 206 through the threaded hole and the connecting plate 205 is restricted by the slider 203, the rotation of the adjusting screw 206 will drive the connecting plate 205 to move in the extension direction of the through slide groove 204, thereby driving the corresponding lifting plate 201 to move synchronously inside the punching roller 1, thereby driving the corresponding group of thorns 4 to move synchronously, and adjusting the length of the part of the thorns 4 extending out of the punching roller 1.

[0028] Furthermore, one end of the adjusting screw 206 close to the second mounting plate 208 extends to the other side of the second mounting plate 208 through the through hole and is fixedly connected to the adjusting knob 209 .

[0029] The adjustment knob 209 is provided to facilitate the staff to turn the adjustment screw 206 to adjust the length of the part of the thorn-like object 4 extending out of the punching roller 1. At the same time, one end of each adjustment screw 206 with the adjustment knob 209 is oriented toward the axis of the punching roller 1, so the staff's hands will be close to the axis of the punching roller 1 during operation, avoiding the occurrence of danger due to the staff's hands being on the relatively outer part of the punching roller 1 during operation, thereby further improving safety during use.

[0030] See also Figure 4 Each thorn-shaped object 4 includes a pointed cone 401, and one end of a mounting bolt 402 is fixedly connected to the bottom of the pointed cone 401. A plurality of threaded slots with positions and sizes corresponding to the mounting bolts 402 are provided on the surface of one side of the lifting plate 201. Each pointed cone 401 is detachably connected to the corresponding lifting plate 201 through the cooperation between the mounting bolt 402 and the threaded slot.

[0031] The pointed cone 401 is threadedly connected to the lifting plate 201 by installing bolts 402, so that the pointed cone 401 can be easily disassembled. Therefore, when in use, the distance between each group of pointed cones 401 can be adjusted according to needs, so that the lateral spacing of the holes can be adjusted according to the drilling requirements, further reducing the limitations in use and improving convenience of use.

[0032] Furthermore, a plurality of evenly distributed diameter scale marks 403 are provided on the outer wall of the pointed cone 401 along its extension direction.

[0033] Because the pointed cone 401 is a cone structure, its overall structure is a structure with a gradually decreasing diameter from the bottom to the top, so the diameter of the punching can be adjusted by adjusting the length of the part of the pointed cone 401 extending from the punching roller 1. Each diameter scale mark 403 marks the diameter of the pointed cone 401 at the corresponding position. By setting the diameter scale mark 403, it is convenient for the staff to adjust the rotating punching diameter, thereby improving convenience in use.

[0034] Working principle: one end of the punching roller 1 is rotatably installed on the rewinder so that it is located on one side between two conveying rollers for conveying the film, and then a driving device such as a motor that can drive the punching roller 1 to rotate independently is connected to the punching roller 1, so that the agricultural film is punched by using several groups of thorns 4 arranged circumferentially on the punching roller 1 during the process of conveying the rolled agricultural film through the rewinder. During the punching process, the length of the part of the thorns 4 extending out of the punching roller 1 can be adjusted by the lifting and adjusting component 2, thereby adjusting the diameter of the punched holes. At the same time, the lifting and adjusting component 2 can also be used to retract several groups of thorns 4 to change the longitudinal spacing of the holes. Secondly, the thorns 4 and the lifting and adjusting component 2 are detachably connected, so the spacing between each group of thorns 4 can also be adjusted as needed, thereby adjusting the lateral distance of the holes, reducing limitations and inconveniences in use, and improving the work efficiency of punching holes in the agricultural film.

[0035] It should be noted that the specific model specifications of the rewinder and the drive device need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The power supply and principle of the rewinding machine and the driving device are clear to those skilled in the art and will not be described in detail here.

[0037] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
