Description

Technical Field

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

[0002] In the process of planting flue-cured tobacco, the land needs to be leveled first, then ridges are made. Holes are dug at certain intervals on the ridges, and tobacco seedlings are planted into the holes and covered with soil. Finally, a film is laid on top, and an opening is made at the seedling to pull the seedling out. The roots of the seedling are covered with soil, and the film is pressed down while covering the roots of the seedling to prevent the film from contacting the seedling. In traditional tobacco seedling planting, when making an opening in the film to pull out the seedling, the film is usually torn open with fingers. However, this can easily break the seedling under the film. At the same time, the opening in the film can be too large or too small, and the opening is messy and does not meet the requirements.

[0003] Utility model patent CN217446039U discloses an agricultural planting film perforation device, including a cylindrical body, an intermediate body, and a vertical rod. The bottom of the cylindrical body is provided with a blade, and symmetrical connecting sleeves are provided on both sides of the top of the cylindrical body, with springs inside the connecting sleeves. Symmetrical sliding rods corresponding to the connecting sleeves are provided below the intermediate body; the sliding rods are slidably connected to the connecting sleeves and in contact with the spring surfaces. A detachable top rod is provided in the middle of the intermediate body, and the lower end of the top rod is conical. The vertical rod is slidably connected to the upper part of the intermediate body and secured with screws. In use, it is combined with… Figure 1 As shown in Figure 5, grasp the handles above the upright pole 3 with both hands, then move the cylinder 1 to the position where the mulch film needs to be cut. Press down firmly, using the blade 101 at the bottom of the cylinder 1 to cut the mulch film. Continue to apply force; the resistance generated between the cylinder 1 and the ground is greater than the elastic force of the spring 103. The sliding rod 201 compresses the spring 103, causing the top rod 4 to move downwards. The conical structure at the bottom of the top rod 4 pierces the cut film, and the conical structure also prevents the film from falling. Then release, and the spring 103 pushes the sliding rod 201 back to its original position, thus completing the process. This patented method allows for the simultaneous cutting and collection of plastic film in a single operation, making it convenient to use. The method involves pressing down on the cylinder to create holes in the plastic film with a blade, and then collecting the cut film using a top rod. However, during use, due to the toughness and deformability of the film itself, the uneven ground causes the film to deform under stress during cutting, making it difficult for the blade to completely cut the film into holes in one go. The cut film remains attached to the main body, requiring secondary cutting, which is time-consuming. Utility Model Content

[0004] The main purpose of this utility model is to provide a perforation device for tobacco field mulch film, which solves the problem that existing mulch film perforation devices are difficult to cut the film completely in one go during the film cutting process.

[0021] 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.

[0022] In one embodiment, see Figure 1 , 3 The present invention relates to a device for punching holes in mulch film in tobacco fields, comprising a punching component and an adjusting component.

[0023] The punching assembly includes a punching cylinder 1 and multiple sets of punching parts 2 with different hole diameters mounted on the punching cylinder 1. The punching cylinder 1 is equipped with an adjustable-length punching handle 3, and the punching parts 2 are equipped with a heating element 4. The multiple sets of punching parts 2 are nested together. The heating element 4 heats up after being energized to transfer heat to the punching parts 2, causing the punching parts 2 to burn through the mulch film and form holes. The adjusting assembly includes multiple sets of adjusting elements 5 movably mounted on the punching cylinder 1. The adjusting elements 5 are connected to the punching parts 2. Different adjusting elements 5 move radially along the punching cylinder 1 under the action of external force, so that the punching parts 2 with different hole diameters move radially along the punching cylinder 1 to contact the mulch film, thereby burning through the mulch film and forming holes of different hole diameters.

[0024] In tobacco cultivation, after ridging and drilling holes, tobacco seedlings are planted into the holes in the ridges. A plastic film is then laid over the ridges, and holes are torn at the seedlings to pull them out. Soil is then used to cover the space between the seedling roots and the film. The holes in the film have different diameters, including 6cm, 15cm, and 20cm. When manually tearing the film to create holes, it is difficult to control the size of the openings and ensure they are around the seedlings. The torn openings are often incomplete, making the process cumbersome and hindering the seedlings from breaking through the film and being covered with soil. In this application, perforation devices 2 with varying hole diameters are used. A heating element 4 is installed inside the perforation device 2. The heating element 4 heats the perforation device 2, transferring heat to it. When the perforation device 2 contacts the film, it burns through the film, creating holes around the seedlings for them to pass through. The film around the holes remains intact, and the center of the holes can be adjusted according to the seedling's position to ensure the correct diameter, facilitating the breaking through of the film and covering with soil.

[0025] Further, see Figure 2 The punching cylinder 1 has an installation cavity 6 inside, and a storage battery 7 is installed inside the installation cavity 6. The storage battery 7 is electrically connected to the heating element 4.

[0026] Preferably, the punching cylinder 1 is a hollow cylinder, and the hollow interior of the punching cylinder 1 forms an installation cavity 6.

[0027] Further, see Figure 1 , 3 The punching component 2 includes a punching ring 201, the axis of which coincides with the axis of the punching cylinder 1, and multiple sets of punching components 2 with different hole diameters are coaxially arranged.

[0028] Preferably, the perforated ring 201 is made of a material with good thermal conductivity, and a metal cylinder can be used as the material for making the perforated ring 201.

[0029] Further, see Figure 3 The heating element 4 includes a heating wire located inside the perforated ring 201.

[0030] Preferably, the heating wire is made of nickel-chromium alloy. The end face of the perforated ring 201 facing the perforated cylinder 1 has a through hole 13. A wire is provided between the battery 7 and the heating wire. The wire passes through the through hole 13 and connects to the heating wire. The connection between the wire and the heating wire is covered with a metal sleeve. The metal sleeve is located inside the through hole 13. An insulation layer of asbestos or other materials is provided inside the metal sleeve to prevent the heat generated by the heating wire from being transferred to the wire.

[0031] Preferably, the punching cylinder 1 is provided with a charging port 8 that is electrically connected to the storage battery 7 so as to charge the storage battery 7.

[0032] In the above setup, the heating wire is powered by the battery 7. After the heating wire is powered on, it generates heat and transfers it to the perforated ring 201 made of metal cylinder. The operator holds the perforation handle 3 and presses the perforation ring 201 down with the tobacco seedling as the center to contact the mulch film. The heat on the perforation ring 201 burns through the mulch film, causing the mulch film inside the perforation ring 201 to separate from the mulch film outside to form holes, thereby forming holes around the tobacco seedlings, which facilitates the covering of the tobacco seedlings with soil.

[0033] In one embodiment, see Figure 1 The punch handle 3 includes a lower handle 301 connected to the punch cylinder 1 and an upper handle 302 movably connected to the lower handle 301. The lower handle 301 is fixedly connected to the center of the top end of the punch cylinder 1. The upper handle 302 moves along the axial direction of the lower handle 301 under the action of external force to adjust the length of the punch handle 3.

[0034] Preferably, the lower handle 301 is a hollow cylinder, and the upper handle 302 is slidably disposed inside the lower handle 301. The lower handle 301 is provided with a screw hole 9, and a stud 10 is provided inside the screw hole 9. The upper handle 302 is provided with positioning holes 11 at intervals. After the stud 10 rotates, it enters into the positioning hole 11, fixing the position between the lower handle 301 and the upper handle 302, thereby fixing the length of the punch handle 3 to accommodate different users. The end of the upper handle 302 away from the lower handle 301 is provided with a crossbar 12 perpendicular to the upper handle 302, which makes it convenient for the user to hold the crossbar 12 for operation.

[0035] In one embodiment, see Figure 1 The adjusting component 5 includes an adjusting screw 501 that passes through the punching cylinder 1, an upper fixing bolt 502 and a lower fixing bolt 503 set on the adjusting screw 501, and the end of the adjusting screw 501 is fixedly connected to the punching ring 201; the upper fixing bolt 502 and the lower fixing bolt 503 are located at the top and bottom ends of the punching cylinder 1, respectively.

[0036] Preferably, the perforated ring 201 is provided with three sets of holes with diameters of 6cm, 15cm and 20cm respectively. The adjusting screw 501 is provided with three sets respectively and is fixedly connected to the three sets of perforated rings 201. The three sets of perforated rings 201 are sleeved with the hole diameter gradually increasing from the inside to the outside. The perforated ring 201 with a diameter of 6cm is located at the innermost part and the perforated ring 201 with a diameter of 20cm is located at the outermost part.

[0037] Preferably, the punching cylinder 1 has three sets of through holes 13 arranged in an arc shape, so that the adjusting screw 501 is staggered after being installed in the through holes 13, which facilitates the rotation of the upper fixing bolt 502 and the lower fixing bolt 503.

[0038] Further, see Figure 1 , 2 The punching cylinder 1 is also provided with a slide rod 14 that is fixedly connected to the punching ring 201, and the slide rod 14 slides through the punching cylinder 1.

[0039] Preferably, the punching cylinder 1 is provided with three sets of sliding holes 15, which are arranged in an arc shape. Each set of punching rings 201 is fixedly connected to a set of adjusting screws 501 and a set of sliding rods 14. The function of the sliding rods 14 is to move when the upper fixing bolt 502 and the lower fixing bolt 503 are loosened to adjust the position of the adjusting screw 501, thereby restricting the degree of freedom of the punching rings 201 in the circumferential direction, so that the punching rings 201 can only move linearly in the radial direction of the punching cylinder 1.

[0040] In the above configuration, by loosening the upper fixing bolt 502 and the lower fixing bolt 503, the adjusting screw 501 can be separated from the punching cylinder 1. The adjusting screw 501 can slide along the through hole 13, thereby adjusting the punching ring 201 connected to the adjusting screw 501 to move towards or away from the punching cylinder 1. If a punching ring 201 with an inner diameter of 15cm is needed, the upper fixing bolt 502 and the lower fixing bolt 503 on the adjusting screw 501 connected to the punching ring 201 with an inner diameter of 15cm are loosened, and the upper fixing bolt 502 is rotated towards the punching cylinder 1. At this time, the constraint between the adjusting screw 501 and the punching cylinder 1 is released, and the punching ring 201 can be pushed... The adjusting screw 501 moves along the through hole 13, causing the 15cm inner diameter punching ring 201 to move towards the punching cylinder 1. The distance between the 15cm inner diameter punching ring 201 and the punching cylinder 1 is greater than the distance between the 6cm and 20cm inner diameter punching rings 201 and the punching cylinder 1. The lower fixing bolt 503 is rotated and moves towards the punching cylinder 1 to cooperate with the upper fixing bolt 502 to clamp the punching cylinder 1, thereby fixing the position of the 15cm inner diameter punching ring 201. During the process of the hand-held punching handle 3 burning through the mulch film through the punching ring 201, the 15cm inner diameter punching ring 201 contacts the mulch film and burns holes in the mulch film.

[0041] The adjustment method for other perforation rings 201 with different apertures is the same as that for perforation rings 201 with an inner diameter of 15cm. In this embodiment, only perforation rings 201 with inner diameters of 6cm, 15cm, and 20cm are listed. In actual production activities, perforation rings 201 with different apertures can be set according to needs so as to burn holes of different apertures on the mulch film. Of course, since the aperture of the perforation rings 201 used each time is different, a control switch needs to be provided on the perforation cylinder 1 accordingly. Each set of switches controls the heating wire in a set of perforation rings 201 to be energized or de-energized, so as to avoid wasting the power in the storage battery 7 by energizing all perforation rings 201 during use.

[0042] 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.
