Description

Technical Field

[0001] This invention relates to the field of agricultural equipment technology, specifically to a fully biodegradable film-covering and perforating device for crop planting. Background Technology

[0002] When using fully biodegradable mulch in the production of fast-growing leafy vegetables, it cannot be directly covered; holes need to be punched in the mulch. Manual punching not only makes it difficult to control the size of the holes, but also results in significant errors in the spacing between the holes. Furthermore, manual punching is time-consuming and labor-intensive, which is not conducive to the utilization of the perforated mulch. On the other hand, having the manufacturer punch the holes in advance increases costs, changes the toughness of the mulch, and makes manual mulching and sowing time-consuming and labor-intensive. In addition, subsequent manual sowing of seeds into the punched holes leads to uneven sowing of crops in each hole, slow speed, low efficiency, and significantly prolongs the sowing time. Therefore, it is necessary to provide a fully biodegradable mulch punching device for crop planting to solve the above technical problems. Summary of the Invention

[0003] The purpose of this invention is to provide a fully biodegradable film-covering perforation device for crop planting, in order to solve the problem mentioned in the background art that requires manual sowing of seeds in the perforated holes. Manual sowing of seeds leads to uneven seed collection in each hole, slow speed, low efficiency, and a significant extension of the sowing time. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fully biodegradable film-covering and perforating device for crop planting, comprising a vehicle body, wherein a connecting roller is mounted on the vehicle body via a connecting frame and a driven shaft, and a sprocket mechanism is connected to the vehicle body via a drive shaft key, wherein one side of the sprocket mechanism is keyed to the driven shaft.

[0005] It also includes a sleeve, which is threadedly connected to the outer side of the connecting roller, and a punch is slidably connected to the inner side of the sleeve. An adjustment mechanism for adjusting the size of the discharge port for different crops and vegetables is connected above the punch. A frame plate is connected below the punch through a first crossbar and a limiting rod, and a flow guiding mechanism for guiding the crops and vegetables to the inner side of the frame plate is installed on both sides of the frame plate. A discharge plate is movably connected below the frame plate through a slider.

[0006] In a further embodiment, the bottom of the connecting frame is connected to a pressure plate for pressing down on both sides of the mulch film via a movable rod, and a scraper is installed below the connecting frame for scraping the soil of the walkway onto the mulch film. The side of the scraper near the mulch film is arc-shaped.

[0007] In a further embodiment, the inner side of the connecting roller is a hollow storage cavity.

[0008] In a further embodiment, the first crossbar is installed at the opening above the sleeve, and the first crossbar and the limiting rod are vertically connected.

[0009] In a further embodiment, the adjusting mechanism includes a telescopic sleeve rod installed at the bottom of the first crossbar, and a first spring is installed on the inner side of the telescopic sleeve rod, and an adjusting rod is threadedly connected to the top of the telescopic sleeve rod.

[0010] In a further embodiment, a push plate is installed on the inner wall of the punch, and a second crossbar is connected to the opening above the punch. The part near the upper end of the punch is circular, and the part near the lower end of the punch is square. The second crossbar and the limiting rod form a sliding structure.

[0011] In a further embodiment, the flow guiding mechanism includes limiting plates installed on both sides of the frame plate, and a guide plate is inserted between the limiting plates and the adjusting plate, and a second spring is connected below the adjusting plate.

[0012] In a further embodiment, the discharge plate is movably connected to the lower end of the punch, and the discharge plate and the slider are slidably connected through a dovetail groove, and the slider is movably connected to the lower end of the frame plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention features a connecting roller and a punch. As the device moves, the punch creates neat holes in the mulch and soil, providing a channel for seed sowing. The contact force between the punch and the soil, in conjunction with a guiding mechanism, adaptively guides the seeds from the storage chamber to the punching position. Simultaneously, the discharge plate opens downwards to ensure the seeds accurately fall into the holes. Compared to existing technologies, this invention not only punches holes in the mulch but also in the soil, and can accurately sow crop seeds inside the holes.

[0015] This invention includes an adjustment mechanism. By rotating the adjustment rod, the first spring is compressed, limiting its extension and retraction. This effectively adjusts the upward micro-movement of the punch, push plate, and telescopic sleeve. The movement of the push plate effectively drives the guide plate to rotate and compresses the adjustment plate to open the discharge port. Compared with existing technologies, this invention allows for manual adjustment of the adjustment structure before sowing different crops, ensuring the accuracy and success rate of sowing.

[0016] This invention includes a sleeve that is threadedly connected to the outer side of the connecting roller, facilitating the disassembly and installation of the punch and the sleeve. When the sleeve is disassembled, a matching threaded sleeve is used to seal and tighten the hole created after the sleeve is disassembled, thereby preventing leakage of the seeds inside the storage chamber. Compared with existing technologies, this invention allows for adjustment of the punching and sowing spacing and depth according to different types of crops.

[0017] In summary, this equipment automatically completes the processes of mulching, punching holes, and sowing, achieving high speed and efficiency, significantly shortening planting time and improving agricultural production efficiency. The automated equipment replaces manual operation, reducing labor input and costs, while also alleviating labor intensity. The equipment can control the sowing rate, ensuring uniformity and depth, thus improving seed germination rate and crop yield. Furthermore, the equipment requires no power control unit, greatly saving costs. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-8 An embodiment of the present invention provides a fully biodegradable film-covering and perforating device for crop planting, comprising a vehicle body 1, a connecting roller 4 mounted on the vehicle body 1 via a connecting frame 2 and a driven shaft 3, and a sprocket mechanism 5 connected to the vehicle body 1 via a drive shaft key, one side of the sprocket mechanism 5 being keyed to the driven shaft 3; further comprising a sleeve 6, the sleeve 6 being threadedly connected to the outer side of the connecting roller 4, and a punch 10 being slidably connected to the inner side of the sleeve 6; an adjustment mechanism 8 for adjusting the size of the discharge port for different crop varieties is connected above the punch 10; a frame plate 9 is connected below the punch 10 via a first crossbar 7 and a limiting rod 701, and a guide mechanism 11 for guiding crop varieties to the inner side of the frame plate 9 is installed on both sides of the frame plate 9; and a discharge plate 12 is movably connected below the frame plate 9 via a slider 1201.

[0029] The bottom of the connecting frame 2 is connected to a pressure plate 201 for pressing down on both sides of the mulch film via a movable rod. A scraper 202 for scraping the soil of the walkway onto the mulch film is installed below the connecting frame 2. The side of the scraper 202 near the mulch film is arc-shaped. This structure design allows the scraper 202 to scrape the soil inside the walkway onto the mulch film, thereby effectively pressing and limiting both sides of the mulch film.

[0030] The inner side of the connecting roller 4 is a hollow storage cavity 401. This structure allows crop seeds to be stored inside the storage cavity 401, which facilitates later perforation and sowing.

[0031] The first crossbar 7 is installed at the opening above the sleeve 6, and the first crossbar 7 and the limiting rod 701 are vertically connected. The adjusting mechanism 8 includes a telescopic sleeve 801 installed at the bottom of the first crossbar 7, and a first spring 802 is installed on the inner side of the telescopic sleeve 801. An adjusting rod 803 is threadedly connected to the top of the telescopic sleeve 801. A push plate 1001 is installed on the inner wall of the punch 10, and a second crossbar 1002 is connected to the opening above the punch 10. The part near the upper end of the punch 10 is round, and the part near the lower end of the punch 10 is square. The second crossbar 1002 and the limiting rod 701 form a sliding structure. This structure design allows the adjusting mechanism 8 to be connected to the sleeve 6 through the first crossbar 7. By rotating the adjusting rod 803, the first spring 802 can be squeezed, so that the extension and contraction of the first spring 802 is limited, thereby adjusting the upward micro-movement of the punch 10, the push plate 1001, and the telescopic sleeve 801.

[0032] The flow guiding mechanism 11 includes limiting plates 1101 installed on both sides of the frame plate 9, and a guide plate 1102 is inserted between the limiting plate 1101 and the adjusting plate 1103. A second spring 1104 is connected below the adjusting plate 1103. With this structure, when the punch 10 drives the push plate 1001 to move slightly upward, it can drive the guide plate 1102 to rotate around the central movable rod. When the guide plate 1102 rotates, it can push the adjusting plate 1103 downward in conjunction with the second spring 1104. At this time, an inclined guide hole will be formed between the guide plate 1102 and the limiting plate 1101, so as to effectively guide a small amount of vegetables inside the punch 10 into the inner side of the frame plate 9.

[0033] The discharge plate 12 is movably connected to the lower end of the punch 10, and the discharge plate 12 and the slider 1201 are slidably connected through the dovetail groove. The slider 1201 is movably connected to the lower end of the frame plate 9. With this structure, when the punch 10 moves upward, it will also drive the discharge plates 12 on both sides below to move upward. Under the action of the limiting rod 701, the frame plate 9 and the slider 1201, the corresponding discharge plates 12 on the left and right sides will open to the sides, so that the seeds inside the frame plate 9 are sown inside the holes, thereby completing the sowing of the seeds.

[0034] Working principle: When using the fully biological mulch film, first push the vehicle body 1 to the crop planting area and adjust the tires on both sides of the vehicle body 1 to the corresponding walkways on both sides of the mulch film. When pushing the vehicle body 1, the drive shafts of the tires on both sides can drive the transmission belt on the inner side of the vehicle body 1 to rotate, which in turn drives the film roll to rotate counterclockwise. This causes the film roll to be released as the vehicle body 1 moves. The pressure plate 201 presses the film roll released on both sides of the raised soil into the walkway. Then, the scraper 202 pushes the soil on the inner side of the walkway upwards and to both sides of the film roll, so that the soil compacts the mulch film.

[0035] Because the mulch film covers and adheres to the raised soil, and the bottom cut surface of the connecting roller 4 also adheres to the mulch film, the cut surface of the connecting roller 4 can contact the mulch film and the raised soil. When the vehicle body 1 moves, the rotation of the rear wheels can drive the driven shaft 3 and the connecting roller 4 to rotate through the sprocket mechanism 5, and at the same time drive the sleeve 6 and the punch 10 to revolve around the driven shaft 3. (It should be noted that before punching holes in the mulch film, the workers have already put the vegetable seeds into the storage cavity 401 from the door panel on the side of the connecting roller 4, and as the connecting roller 4 rotates, the vegetable seeds will also enter the sleeve 6 and the punch 10 below due to their own gravity.) When the punch 10 contacts and punches the mulch film, it can also simultaneously... The soil inside the membrane is perforated. When the punch 10 penetrates the membrane and perforates the soil, the soil can generate a certain resistance force on the punch 10. At this time, the punch 10 moves slightly upward under the micro-elastic action of the telescopic sleeve 801 and the first spring 802. Therefore, when the punch 10 drives the push plate 1001 to move slightly upward, it can drive the guide plate 1102 to rotate around the central movable rod. When the guide plate 1102 rotates, it can push the adjusting plate 1103 downward in conjunction with the second spring 1104. At this time, an inclined guide hole will be formed between the guide plate 1102 and the limiting plate 1101, so as to effectively guide a small amount of vegetable seeds inside the punch 10 into the inner side of the frame plate 9.

[0036] As the punch 10 moves upward, it also drives the discharge plates 12 on both sides below to move upward. Under the action of the limiting rod 701, the frame plate 9 and the slider 1201, the corresponding discharge plates 12 on the left and right sides open to the sides, so that the seeds inside the frame plate 9 are scattered inside the holes, thus completing the sowing of the seeds. An adjusting rod 803 is threadedly connected above the telescopic sleeve rod 801. By rotating the adjusting rod 803, the first spring 802 can be squeezed, so that the extension and contraction of the first spring 802 is limited. This allows the upward micro-movement of the punch 10, the push plate 1001 and the telescopic sleeve rod 801 to be adjusted. Therefore, after the upward dimension of the push plate 1001 is adjusted, the rotation angle of the guide plate 1102 can also be adjusted, thereby adjusting the opening size of the guide plate 1102. This allows the size of the discharge port to be effectively adjusted for different seeding amounts.

[0037] As the vehicle body 1 moves, the connecting roller 4, sleeve 6, and punch 10 rotate around the driven shaft 3. When the punch 10 leaves the soil hole, it will be elastically reset by the first spring 802 and the second spring 1104, which will drive the punch 10, push plate 1001, second crossbar 1002, adjusting plate 1103, guide plate 1102, discharge plate 12, and slider 1201 to reset, thereby realizing continuous operation of mulching, punching, and sowing.

[0038] In addition, since the sleeve 6 and the connecting roller 4 are connected by threads, it is convenient for operators to adjust the hole spacing and drilling depth according to different crops. When the sleeve 6 is disassembled, the hole at the disassembly point can be sealed by the sleeve 6 with threads on the outside, thereby preventing the seeds inside the storage chamber 401 from spilling out. In this way, a series of tasks are completed.
