Description

Technical Field

[0001] This utility model relates to the field of easy-tear mulch film technology, specifically to a mulch film perforation device and an easy-tear mulch film formed by the mulch film perforation device. Background Technology

[0002] Currently, plastic film is widely used in agricultural production for water retention, fertilizer retention, heat preservation, and weed suppression. However, removing existing plastic film after use is often difficult. Traditional plastic film is usually a complete film structure, with both sides covered by soil. When farmers try to remove the film, it is tightly held down by the soil on both sides, requiring a lot of physical strength and time. This is especially true for farmland with large areas of plastic film, where removing the film becomes a heavy task. Moreover, the film is easily torn during the removal process, making it difficult to recycle completely. The film fragments left in the soil not only affect soil structure and hinder crop root growth but also cause serious environmental pollution, which is detrimental to sustainable agricultural development. Therefore, a type of plastic film that is easy to remove is needed to solve the above-mentioned problems of existing plastic film. Utility Model Content

[0003] The main purpose of this utility model is to provide a mulch film punching device and an easy-tear mulch film formed by the mulch film punching device, so as to solve the problem that it is difficult to peel off the mulch film when it is recycled after use because both sides of the mulch film are pressed down by soil.

[0004] To achieve the above objectives, this utility model provides a mulch film perforation device and an easy-tear mulch film formed by the mulch film perforation device, including a film covering assembly. The film covering assembly includes a film covering vehicle body and a connecting roller disposed on the film covering vehicle body; the film covering vehicle body is provided with a film pressing roller and a film covering shovel; a roll of mulch film is installed on the connecting roller; and further includes:

[0005] The connecting assembly includes a connector disposed on the laminating vehicle body and a mounting plate disposed on the connector; the connector is located above the center of the connecting roller; the mounting plate is located between the laminating shovels;

[0006] The film-opening assembly includes a film-opening component mounted on a mounting plate and a pushing component connected to the film-opening component; the film-opening component is arranged perpendicular to the mounting plate so that the end of the film-opening component is vertically downward; the pushing component reciprocates along the axial direction of the film-opening component under the action of external force, so as to drive the film-opening component to move upward to detach from the external mulch film or to move downward to pierce the external mulch film.

[0007] As a further improvement of this utility model, the connecting member includes a connecting rod fixedly connected to the film-covering vehicle body; the vertical distance from the connecting rod to the connecting roller is greater than the radius of the film roll.

[0008] As a further improvement of this utility model, the distance from the mounting plate to the film-coating vehicle body is greater than the distance from the film-coating shovel to the film-coating vehicle body.

[0009] As a further improvement of this utility model, the mold opening component includes a mold opening rod slidably disposed on the mounting plate and a mold opening pin disposed on the mold opening rod; the length of the mold opening rod is greater than the length between the connecting rod and the ground, and a spring is provided between the mold opening rod and the mounting plate; the pushing component includes a motor disposed on the mounting plate and a cam connected to the output end of the motor; the outer edge of the cam is slidably connected to the mold opening rod.

[0010] As a further improvement of this utility model, a connecting plate is provided at the end of the mold opening rod away from the cam; the mold opening pins are installed at intervals on the connecting plate.

[0011] This utility model also includes an easy-tear mulch film, wherein the mulch film is provided with multiple sets of small holes at intervals.

[0012] The beneficial effects of this utility model are reflected in:

[0013] The mulch film is laid by moving forward in a mulching vehicle, and soil is covered onto the mulch film by the action of the mulching shovel. By setting a mold-opening component connected to the mulching vehicle, the mold-opening component is pushed by the pusher to pierce small holes in the mulch film after the soil covering operation has been completed. This prevents the mulch film from tearing and being damaged in the middle during the soil covering process. As the mulching vehicle moves forward, the mold-opening component pierces multiple sets of small holes at intervals on the mulch film, which makes it easy to tear the mulch film from the middle when it is used up and collected. This ensures that only one side of the mulch film is covered with soil, and it is easier to separate the covering soil from the mulch film when pulling the mulch film, so that the mulch film can be completely recycled.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] In one embodiment, see Figure 1 The present invention relates to a mulch film perforation device and an easy-tear mulch film formed by the mulch film perforation device, comprising a film covering component, a connecting component, and a film opening component.

[0020] The film covering assembly includes a film covering vehicle body 1 and a connecting roller 2 mounted on the film covering vehicle body 1. The film covering vehicle body 1 is equipped with a film pressing roller 3 and a film covering shovel 4. The film roll 5 is mounted on the connecting roller 2. The connecting assembly includes a connector 6 mounted on the film covering vehicle body 1 and a mounting plate 7 mounted on the connector 6. The connector 6 is located above the middle of the connecting roller 2, and the mounting plate 7 is located between the film covering shovels 4. The film opening assembly includes a mold opening component 8 mounted on the mounting plate 7 and a pushing component 9 connected to the mold opening component 8. The mold opening component is set perpendicular to the mounting plate 7 so that the end of the mold opening component 8 is vertically downward. Under the action of external force, the pushing component 9 reciprocates along the axial direction of the mold opening component 8 to drive the mold opening component 8 to move upward to detach from the external film or move downward to pierce the external film.

[0021] When using the film-covering vehicle 1 as a film-covering device, the film is installed on the film-covering vehicle 1. The movement of the film-covering vehicle 1 drives the film roll 5 to roll and release the film. The film is then pressed down by the pressure rollers 3 located on both sides of the film, so that the film covers the land. At the same time, the film-covering shovel 4 located behind the pressure rollers 3 moves and carries up soil to cover the film, so that the film is laid on the land. The film-covering vehicle 1 is a mature product and is under application. No improvement is proposed for the film-covering vehicle 1. The main difference is that the mold-opening part 8 makes intermittent perforations on the already laid film, so that the middle part of the film changes from a complete state to an easy-tear structure. The reason for opening the easy-tear hole structure in the middle of the film after the film is laid and covered with soil is that when the pressure rollers 3 press down on the two ends of the film, the film is subjected to tension in both directions. In this solution, opening the easy-tear hole after the film is covered can prevent the film from being torn from the middle by the pressure rollers 3.

[0022] Further, see Figure 1 , 2 The connector 6 includes a connecting rod 601 that is fixedly connected to the film-covering vehicle body 1. The vertical distance from the connecting rod 601 to the connecting roller 2 is greater than the radius of the film roll 5.

[0023] Preferably, the connecting rod 601 is connected to the coated vehicle body 1 by welding, and the connecting rod 601 is located in the middle of the coated vehicle body 1.

[0024] Further, see Figure 1 The distance from the mounting plate 7 to the film-covering vehicle body 1 is greater than the distance from the film-covering shovel 4 to the film-covering vehicle body 1.

[0025] Preferably, the length of the connecting rod 601 is greater than the distance from the film-covering shovel 4 to the film-covering vehicle body 1, and the distance from the mounting plate 7 to the film-covering shovel 4 is between 5cm and 10cm.

[0026] In the above setup, the mulch film is laid on the land by the mulching vehicle 1, the pressing roller 3 presses down on both sides of the mulch film, and the mulching shovel 4 turns up the soil on both sides of the mulch film and covers it. The connecting rod 601 and the mounting plate 7 move accordingly and are located above the middle of the mulch film. The mounting plate 7 is positioned further back from the mulching vehicle 1 than the mulching shovel 4 is positioned further back from the mulching vehicle 1, so that when the mold opening part 8 pierces the mulch film, both sides of this part of the mulch film are already covered with soil, thus preventing the mulch film from being torn apart from the middle during the mulching process.

[0027] In one embodiment, see Figure 2 The mold opening component 8 includes a mold opening rod 801 slidably disposed on the mounting plate 7 and a mold opening pin 802 disposed on the mold opening rod 801. The length of the mold opening rod is greater than the length between the connecting rod 601 and the ground. A spring 10 is provided between the mold opening rod 801 and the mounting plate 7. The pushing component 9 includes a motor 901 disposed on the mounting plate 7 and a cam 902 connected to the output end of the motor 901. The outer edge of the cam 902 is slidably connected to the mold opening rod 801.

[0028] Preferably, a first retaining ring 11 is provided at the end of the mold opening rod 801 that is far from the mold pin 802, and a second retaining ring 12 is provided on the outer wall of the mold opening rod 801 adjacent to the mold opening pin 802. A spring 10 is sleeved on the mold opening rod 801 and located between the first retaining ring 11 and the mounting plate 7. The spring 10 abuts against the first retaining ring 11. The second retaining ring 12 is located at the bottom end of the mounting plate 7. The arrangement of the first retaining ring 11 and the second retaining ring 12 ensures that the mold opening rod 801 will not detach from the mounting plate 7.

[0029] Preferably, the mounting plate 7 is provided with a sliding hole 13, the film opening rod is located in the sliding hole 13, and the first retaining ring 11 and the second retaining ring 12 are located at both ends of the retaining ring.

[0030] Preferably, the cam 902 is in contact with the first retaining ring 11.

[0031] Further, see Figure 2 The end of the mold opening rod 801 away from the cam 902 is provided with a connecting plate 14, and the mold opening pins 802 are installed on the connecting plate 14 at intervals.

[0032] Preferably, the connecting plate 14 is vertically connected to the mold opening rod 801.

[0033] In the above setup, the motor 901 adopts an existing structure. After the motor 901 is energized, it rotates, driving the cam 902 to rotate. After the cam 902 rotates, it presses down on the film-opening rod, compressing the spring 10. During the downward movement of the film-opening rod 801, the film-opening needle 802 moves downward and pierces the film. The connecting rod 601 moves with the film-covering vehicle 1, driving the film-opening needle 802 to move and form small holes 15 at intervals on the film. The rotation speed of the electrode is selected according to the forward speed of the film-covering vehicle 1. For example, if the forward speed of the film-covering vehicle 1 is 5 meters / minute, then the film-opening... The forward speed of needle 802 is also 5 meters / minute. Every time motor 901 rotates, the mold opening rod 801 presses down once, causing the mold opening needle 802 to pierce a small hole 15 in the mulch film. The diameter of the mold opening needle 802 is 1mm. The spacing between adjacent small holes 15 on the mulch film is 2mm. Therefore, 2000 small holes 15 are needed on a 5-meter-long mulch film. The speed of motor 901 can be selected to be 2000 rpm to ensure the distance between the small holes 15 and the number of small holes 15, so as to facilitate tearing the mulch film from the middle when it is subsequently recycled.

[0034] In this embodiment, the mulching vehicle body 1 is connected to the connecting rod 601, thereby connecting the motor 901, the mold opening rod 801, and the mold opening needle 802 to the mulching vehicle body 1. During the mulching process, the motor 901 rotates and drives the mold opening rod 801 and the mold opening needle 802 to continuously pierce the mulch film, thereby opening a small hole 15 in the middle of the mulch film. This facilitates tearing the mulch film in the middle during subsequent mulch film recycling, so that the stress surface of the mulch film is the soil on one side, which makes it easier to completely recycle the mulch film from the soil and avoids mulch film fragments remaining in the soil.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
