Description
Technical Field
[0001] This utility model relates to the technical field of a punching device for fully biodegradable agricultural mulch film, and more specifically, to a mulch film punching device. Background Technology
[0002] Mulch film, also known as ground cover film, is used to cover the ground to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, and help promote plant growth. During the sowing process, in order to avoid the mulch film from hindering crop growth, it is necessary to use a perforating device to make holes in the mulch film at corresponding positions so that the crops can grow through the holes.
[0003] Crops in farmland typically have row spacing and plant spacing. Row spacing refers to the distance between two adjacent rows of crops, while plant spacing refers to the distance between two adjacent plants in the same row.
[0004] Chinese patent CN220986902U discloses a plastic mulch film punching device, including a mounting base. A protective cover is fixedly connected to the upper end of the mounting base, and a sliding groove is opened in the middle of the upper end of the mounting base. A battery pack is fixedly connected to the middle of the upper end of the mounting base. The plastic mulch film punching device described in this utility model has a storage structure that allows it to be stored after use and its height to be adjusted during use. At the same time, the punching structure can be adjusted according to the actual use situation to improve the use effect.
[0005] However, in actual use, because the spacing between crops varies, and each set of punching rods of this device makes four holes per rotation, the plant spacing is fixed and not suitable for specific situations. Furthermore, there is also row spacing between crops. Adjusting the row spacing of each set of punching rods requires repeatedly unscrewing the nuts, which is quite troublesome. In addition, the row spacing is not clearly indicated, resulting in inaccurate results and reducing the user experience. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] As attached Figure 1-9 The punching device for a fully biodegradable agricultural mulch film shown includes a main shell 1, a handle 2 fixedly connected to the front end of the main shell 1, two rolling wheels 3 fixedly connected to both sides of the main shell 1, a sliding groove 4 opened on the top of the main shell 1, a storage mechanism is provided inside the sliding groove 4, and a punching mechanism is fixedly connected to the bottom of the storage mechanism.
[0033] The punching mechanism includes two lifting plates 5 disposed inside the main body shell 1. The front and rear ends of the two lifting plates 5 are fixedly connected to a connecting plate 6. The left end of the left lifting plate 5 is fixedly connected to a first motor 7. The output end of the first motor 7 is fixedly connected to a rotating rod 8. Both ends of the rotating rod 8 are provided with turntables 9.
[0034] Four symmetrically arranged fixed rods 10 are rotatably connected between the two turntables 9, and four fixing holes 11 are opened on one side of each fixed rod 10.
[0035] The fixed rod 10 has four symmetrical sliding grooves 12 on its surface. Three of the sliding grooves 12 have multiple perforated rods 13 at their top. Each of the four sliding grooves 12 has a rubber layer 14 inside. Each perforated rod 13 has a locking block 15 at its bottom, and the locking block 15 is slidably connected to the sliding groove 12. Of the four sliding grooves 12, the first has one perforated rod 13, the second has two perforated rods 13, the third has three perforated rods 13, and the fourth has no perforated rod 13 inside.
[0036] One of the turntables 9 has four sets of fixing mechanisms on one side that correspond to the fixing ports 11;
[0037] The bottom of the punching rod 13 is made of magnetic material, and an iron strip is provided at the center of the fixing rod 10.
[0038] Both ends of the threaded rod 17 are rotatably connected to the inner wall of the main body shell 1, and the rectangular slider 19 is slidably connected to the sliding groove 4.
[0039] Both ends of the rotating rod 8 are rotatably connected to the lifting plate 5, and both lifting plates 5 are fixedly connected to the lower mounting ears 22.
[0040] The punching rod 13 is attached to the rubber layer 14, and the surfaces of the four fixing rods 10 are provided with distance scales 34. Through the above operations, the number and specific position of the punching rods 13 on the sliding groove 12 can be quickly adjusted according to the row spacing and plant spacing of the crops.
[0041] Specifically, the punching mechanism is adjusted according to the actual usage to change the plant spacing of the crops. If you want to change the plant spacing, there are three situations: one is that the turntable 9 rotates once and only punches one row of holes. At this time, rotate the three fixed rods 10 until the three sliding slots 12 with no punching rods 13 on the top face outwards. Another situation is that the turntable 9 rotates once and only punches two rows of holes. At this time, rotate the two opposite fixed rods 10 until the two sliding slots 12 with no punching rods 13 on the top face outwards. The third situation is that the turntable 9 rotates once and only punches four rows of holes. At this time, rotate the four opposite fixed rods 10 until the four sliding slots 12 with punching rods 13 on the top face outwards. The specific number of holes in each row is determined by the number of punching rods 13 on the fixed rod 10. After rotating the fixed rod 10, the position of the fixed rod 10 is fixed by the fixing mechanism.
[0042] In a specific embodiment, as shown in the appendix Figure 1 , 2As shown in Figure 3, the storage mechanism includes threaded rods 17 rotatably disposed on both sides of the main body shell 1, and a second motor 18 for driving the threaded rods 17 is fixedly disposed on one side of the main body shell 1. Two rectangular sliders 19 with opposite internal threads are threadedly connected to the threaded rods 17. The lower ends of the two rectangular sliders 19 are fixedly connected to upper mounting ears 20. Transmission rods 21 are hinged to the two sets of upper mounting ears 20. The lower ends of the two transmission rods 21 are hinged to lower mounting ears 22. Through the above operation, the height of the punching mechanism can be adjusted according to whether the plastic film is flat-bottomed or ridged.
[0043] Specifically, first, it is determined whether the plastic film is for flat-bottomed or ridged-topped covering. The height of the punching mechanism is adjusted using the storage structure. The second motor 18 is started, which drives the threaded rod 17 to rotate. The two rectangular sliders 19 with opposite internal threads separate under the constraint of the sliding groove 4, which causes the two upper mounting ears 20 to separate. At the same time, the positions of the transmission rod 21 and the lower mounting ear 22 change, thereby changing the height of the punching mechanism at the bottom of the storage mechanism.
[0044] In a specific embodiment, as shown in the appendix Figure 4 , 5 As shown in Figure 6, the fixing mechanism includes a base 24 fixedly connected to one side of the turntable 9. An L-shaped extension strip 25 is fixedly connected to the top of the base 24. A sleeve 26 is fixedly connected to one side of the L-shaped extension strip 25. Placement slots 27 are provided on both sides of the sleeve 26. A retaining ring 31 is fixedly connected to the inner wall of the sleeve 26. An extension rod 28 is slidably connected inside the sleeve 26. A spring rod 29 is fixedly connected to the top of the extension rod 28. A telescopic spring 30 is movably sleeved on the surface of the spring rod 29. The bottom and top of the telescopic spring 30 are fixedly connected to the top of the extension rod 28 and the retaining ring 31, respectively. The spring rod 29 is slidably connected to the retaining ring 31. A rotating rod 32 is fixedly connected to the top of the spring rod 29. Two symmetrical locking rods 33 are fixedly connected to the surface of the rotating rod 32. The locking rods 33 are slidably connected to the placement slots 27. Through the above operations, the position of the fixing rod 10 can be easily fixed.
[0045] Specifically, when it is necessary to adjust the number of punch rods 13 on the sliding slot 12, first pull the rotating rod 32. The rotating rod 32 drives the spring rod 29 and the extension rod 28 to move upward. The spring rod 29 slides past the retaining ring 31, and the telescopic spring 30 is blocked by the retaining ring 31. At this time, the telescopic spring 30 is compressed by the extension rod 28, and the extension rod 28 is pulled out of the fixing port 11. When the locking rod 33 on the surface of the rotating rod 32 is brought out of the sleeve 26 from the placement slot 27, rotate the rotating rod 32, and the locking rod 33 is locked and fixed to the outer wall of the sleeve 26.
[0046] Then rotate the turntable 9 until it reaches the sliding slot 12 with a suitable punching density. Then rotate the rotating rod 32 until the locking rod 33 is aligned with the placement slot 27. Release the hand, and the telescopic spring 30 will return to its original position and assist the extension rod 28 at the bottom of the spring rod 29 to insert into the fixing port 11, thereby fixing the position of the sliding slot 12 that meets the conditions.
[0047] The working principle of this utility model is as follows: When the agricultural film in the field needs to be punched, the device is placed on the film. First, it is determined whether it is a flat-bottomed plastic film or a ridge-covered film. The height of the punching mechanism is adjusted by the storage structure. The second motor 18 is started. The second motor 18 drives the threaded rod 17 to rotate. The two rectangular sliders 19 with opposite internal threads separate under the restriction of the sliding groove 4, which drives the two upper mounting ears 20 to separate. At the same time, the positions of the transmission rod 21 and the lower mounting ear 22 change, thereby changing the height of the punching mechanism at the bottom of the storage mechanism.
[0048] After adjusting the height, adjust the punching mechanism according to the actual usage of the crop spacing. If you want to change the punching spacing, there are three situations.
[0049] One method involves rotating the turntable 9 once to drill only one row of holes. At this time, rotate the three fixed rods 10 until the three sliding slots 12 with no drilling rods 13 at the top face outwards.
[0050] One method involves rotating the turntable 9 once to drill only two rows of holes. At this point, rotate the two opposing fixed rods 10 until the sliding slots 12 of the two top-hole-free drilling rods 13 face outwards.
[0051] One method involves rotating the turntable 9 once to drill four rows of holes. At this time, rotate the four opposing fixed rods 10 until the four sliding slots 12 with the drilling rods 13 at the top face outwards.
[0052] The specific number of holes in each row is determined by the number of punching rods 13 on the fixed rod 10;
[0053] After rotating the fixed rod 10, the position of the fixed rod 10 is fixed by the fixing mechanism;
[0054] Specifically, by pulling the rotating rod 32 and rotating it until the locking rod 33 is aligned with the placement slot 27, the hand is released and the telescopic spring 30 returns to its original position, which will assist the extension rod 28 at the bottom of the spring rod 29 to insert into the fixing port 11, thereby fixing the position of the fixing rod 10 and thus changing the spacing between the holes.
[0055] After adjusting the plant spacing, the row spacing can also be adjusted. The row spacing of the punching rod 13 on the fixed rod 10 can be adjusted according to the specific location of the crop and the distance scale 34 on the surface of the fixed rod 10. Pull up the punching rod 13. At this time, the locking block 15 on the surface of the punching rod 13 moves upward in the sliding groove 12, so that the magnetic attraction between the bottom of the punching rod 13 and the iron block at the center of the fixed rod 10 is weakened. At this time, slide the punching rod 13 in the sliding groove 12. When it moves to the appropriate position, put down the punching rod 13, so that the bottom of the punching rod 13 and the iron block at the center of the fixed rod 10 are magnetically attracted. The iron block and the rubber layer 14 together fix the position of the punching rod 13 to prevent it from sliding after it is fixed.
[0056] After adjusting the specific position of the punching rod 13 on the fixed rod 10, start the first motor 7 to drive the rotating rod 8 to rotate, thereby driving the two turntables 9 and the fixed rod 10 set between the two turntables 9 to rotate, so that the punching rod 13 on the sliding groove 12 rotates to punch holes in the mulch film.
[0057] After punching is completed, the second motor 18 is started to store the device. The second motor 18 drives the threaded rod 17 to rotate, and the two rectangular sliders 19 with opposite internal threads come together under the restriction of the sliding groove 4, which drives the two upper mounting ears 20 to come together. At the same time, the positions of the transmission rod 21 and the lower mounting ear 22 change, thereby reducing the distance between the storage mechanism and the punching mechanism, thus achieving the purpose of storing the device.
[0058] 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.
