Description

Technical Field

[0001] The invention relates to the technical field of agricultural equipment, in particular to a fully biodegradable film covering and punching device for crop planting. Background Art

[0002] The hot summer and autumn are the off-seasons for vegetable production and supply. In order to solve the problem of vegetable supply in the market during the summer shortage period, fast-growing leafy vegetables can be planted to meet market demand. Due to their short growth cycle, which is generally only 20 to 25 days, they are also often used as rush-sown varieties for disaster relief. Leafy vegetables in summer and autumn are harmed by various weeds throughout their growth period, which can easily cause great losses. Herbicides are often used for prevention and control in production.

[0003] Fully biodegradable film is a new type of agricultural film with biodegradability, which is produced by modifying polybutylene terephthalate-adipate (PBAT), polylactic acid (PLA), polypropylene carbonate (PPC), polyhydroxyalkanoate (PHA) and other materials as the main raw materials. The application of fully biodegradable film on summer and autumn leafy vegetables can reduce the use of herbicides and other pesticides, and produce green leafy vegetables. At the same time, there is no need to pick up and recycle residual film, which will not affect the sowing of the next crop of leafy vegetables.

[0004] When fully biodegradable film is used in the production of fast-growing leafy vegetables, it cannot be directly covered. Some holes need to be punched in the biodegradable film. Manual punching not only cannot control the size of the holes, but there is also a large error in the spacing between the holes. Moreover, manual punching is time-consuming and labor-intensive, which is not conducive to the utilization of the holes in the biodegradable film. Punching holes in advance by the manufacturer increases the cost, changes the toughness of the film, and is time-consuming and labor-intensive when manually laying the film and sowing. At the same time, manual sowing and planting are required in the holes that have been punched. Manual sowing and planting will result in uneven sowing amount of crops in each hole, slow speed, and low efficiency, which greatly prolongs the sowing time. Therefore, it is necessary to provide a fully biodegradable film punching equipment for crop planting to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide a fully biodegradable film covering and punching equipment for crop planting, so as to solve the problem proposed in the above background technology that seeds need to be manually sown and planted in the punched holes. Manual sowing and planting will result in uneven seed collection, slow speed and low efficiency in each hole, which greatly prolongs the sowing time. The technical solution of the present invention is aimed at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above object, the present invention provides the following technical solution: A fully biodegradable film punching device for crop planting, comprising a vehicle body, the vehicle body is equipped with a connecting roller through a connecting frame and a driven shaft, and the vehicle body is connected to a sprocket mechanism through a driving shaft key, and one side of the sprocket mechanism is connected to the driven shaft key; It also includes a sleeve, which is threadedly connected to the outer side of the connecting roller, and a punch is connected to the inner side of the sleeve for lifting and sliding. An adjustment mechanism for adjusting the size of the discharge port for different crops and vegetable seeds is connected above the punch. A frame plate is connected below the punch through a first cross bar and a limit rod, and a diversion mechanism for guiding the crop and vegetable seeds to the inner side of the frame plate is installed on both sides of the frame plate. A discharge plate is movably connected to the frame plate below through a slider.

[0007] In a further embodiment, the bottom of the connecting frame is connected to a pressure plate for pressing down both sides of the film through a movable rod, and a scraper board for scraping the walkway soil to the top of the pressed film is installed under the connecting frame, and the side of the scraper board close to the film is arc-shaped.

[0008] In a further embodiment, the inner side of the connecting roller is a hollow material storage cavity.

[0009] In a further embodiment, the first cross bar is installed at the upper opening of the sleeve, and the first cross bar and the limiting rod are vertically connected.

[0010] In a further embodiment, the adjustment mechanism comprises a telescopic sleeve rod installed at the bottom of the first cross bar, a first spring is installed on the inner side of the telescopic sleeve rod, and an adjustment rod is threadedly connected to the top of the telescopic sleeve rod.

[0011] In a further embodiment, a push plate is installed on the inner wall of the punch, and a second cross bar is connected to the opening above the punch. The part near the upper end of the punch is round, and the part near the lower end of the punch is square. The second cross bar and the limit rod form a sliding structure.

[0012] In a further embodiment, the guide mechanism includes limit plates installed on both sides of the frame plate, and a material guide plate is inserted between the limit plates and the adjustment plate, and a second spring is connected below the adjustment plate.

[0013] In a further embodiment, the discharge plate is movably connected to the lower end of the punch, and the discharge plate is slidably connected to the slider via a dovetail groove, and the slider is movably connected to the lower end of the frame plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention is provided with a connecting roller and a punch. As the equipment moves, the punch will punch neat holes on the film and the soil to provide a channel for seed sowing. Through the resistance force between the punch and the soil, it can cooperate with the diversion mechanism to adaptively guide the seeds from the storage chamber to the punching position, and can simultaneously open the discharge plate downward to ensure that the seeds accurately fall into the holes. Compared with the existing technology, not only the film can be punched, but also the soil can be punched, and at the same time, the crop and vegetable seeds can be accurately scattered into the inside of the holes. The present invention is provided with an adjustment mechanism, which squeezes the first spring by rotating the adjustment rod. The expansion and contraction amount of the first spring is limited, so that the size of the upward micro-movement of the punch, the push plate and the telescopic sleeve can be effectively adjusted. The movement of the push plate can effectively drive the guide plate to rotate, and squeeze the adjustment plate to open the discharge port. Compared with the existing technology, when sowing different crops, the adjustment structure can be manually adjusted first to ensure the accuracy and success rate of sowing. The present invention is provided with a sleeve, which is connected to the outer side of the connecting roller through a threaded connection, so that the punch head and the sleeve can be easily disassembled and installed. When the sleeve is disassembled, the matching threaded sleeve is used to seal and tighten the hole generated after the sleeve is disassembled, so as to prevent the leakage of vegetable seeds inside the storage cavity. Compared with the existing technology, the punching and sowing spacing and depth can be adjusted according to different types of crops and vegetable seeds. In summary, the equipment automatically completes the film covering, drilling and sowing processes with high speed and efficiency, greatly shortening the planting time and improving agricultural production efficiency. Automated equipment replaces manual operation, reduces manpower input, reduces labor costs, and also reduces labor intensity. The equipment can control the sowing amount, ensure the uniformity and depth of sowing, and improve the seed germination rate and crop yield. In addition, the equipment does not require any power control unit, which greatly saves costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-8 An embodiment of the present invention is a fully biodegradable film punching device for crop planting, comprising a body 1, the body 1 is provided with a connecting roller 4 through a connecting frame 2 and a driven shaft 3, and the body 1 is connected with a sprocket mechanism 5 through a driving shaft key, and one side of the sprocket mechanism 5 is key-connected to the driven shaft 3; it also comprises a sleeve 6, the sleeve 6 is threadedly connected to the outer side of the connecting roller 4, and a punch 10 is connected to the inner side of the sleeve 6 for lifting and sliding, an adjustment mechanism 8 for adjusting the size of the discharge port for different crop and vegetable seeds is connected above the punch 10, a frame plate 9 is connected below the punch 10 through a first cross bar 7 and a limit rod 701, and a guide mechanism 11 for guiding the crop and vegetable seeds 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 to the bottom of the frame plate 9 through a slider 1201.

[0019] A pressure plate 201 for pressing down both sides of the film is connected to the bottom of the connecting frame 2 through a movable rod, and a scraper plate 202 for scraping the soil of the walkway to the top of the downward-pressed film is installed under the connecting frame 2. The side of the scraper plate 202 close to the film is arc-shaped. The design of this structure can scrape the soil on the inner side of the walkway to the top of the downward-pressed film through the scraper plate 202, thereby effectively pressing and limiting both sides of the downward-pressed film.

[0020] The inner side of the connecting roller 4 is a hollow storage cavity 401. The design of this structure enables the crop and vegetable seeds to be stored inside the storage cavity 401, which is convenient for subsequent drilling and sowing.

[0021] The first cross bar 7 is installed at the opening above the sleeve 6, and the first cross bar 7 and the limit rod 701 are vertically connected. The adjusting mechanism 8 includes a telescopic sleeve rod 801 installed at the bottom of the first cross bar 7, and a first spring 802 is installed on the inner side of the telescopic sleeve rod 801, and an adjusting rod 803 is threadedly connected to the top of the telescopic sleeve rod 801. A push plate 1001 is installed on the inner wall of the punch 10, and a second cross bar 1002 is connected to the opening above the punch 10. The part near the upper end of the punch 10 is circular, and the part near the lower end of the punch 10 is square. The second cross bar 1002 and the limit rod 701 constitute a sliding structure. The design of this structure can connect the adjusting mechanism 8 with the sleeve 6 through the first cross bar 7, and the first spring 802 can be squeezed by rotating the adjusting rod 803, so that the telescopic amount of the first spring 802 is limited, so that the size of the upward micro-movement of the punch 10, the push plate 1001 and the telescopic sleeve rod 801 can be adjusted.

[0022] The guide mechanism 11 includes a limit plate 1101 installed on both sides of the frame plate 9, and a guide plate 1102 is inserted between the limit plate 1101 and the adjustment plate 1103, and a second spring 1104 is connected below the adjustment plate 1103. The design of this structure is that when the punch 10 drives the push plate 1001 to move slightly upward, it can drive the guide plate 1102 to rotate around the middle movable rod. When the guide plate 1102 rotates, the adjustment plate 1103 can be pushed downward in cooperation with the second spring 1104. At this time, an inclined guide hole will be formed between the guide plate 1102 and the limit plate 1101, so that a small amount of vegetable seeds inside the punch 10 can be effectively introduced into the inner side of the frame plate 9.

[0023] The discharge plate 12 is movably connected to the lower end of the punch 10, and the discharge plate 12 is slidably connected to the slider 1201 through a dovetail groove, and the slider 1201 is movably connected to the lower end of the frame plate 9. The design of this structure, when the punch 10 moves upward, it will also drive the discharge plates 12 on both sides below to move upward, and under the action of the resistance force of the limit rod 701, the frame plate 9 and the slider 1201, the corresponding discharge plates 12 on the left and right sides are opened to both sides, so that the vegetable seeds on the inside of the frame plate 9 are scattered on the inside of the holes, thereby completing the sowing of the vegetable seeds.

[0024] Working principle: When in use, when covering the whole biological film, first push the vehicle body 1 to the crop planting site, and adjust the tires on both sides of the vehicle body 1 to the corresponding walkways on both sides of the film covering. When pushing the vehicle body 1, the drive shafts of the tires on both sides can drive the transmission belt on the inside of the vehicle body 1 to rotate, and drive the film roll to rotate counterclockwise, so that the film roll is released as the vehicle body 1 moves, and the film roll released on both sides of the ridge soil is pressed down into the walkway through the pressure plate 201, and then the soil on the inside of the walkway is pushed upward on both sides of the film roll through the scraper plate 202, so that the soil is used to compact the film.

[0025] Since the film covers and fits over the ridge soil, and the bottom cross-section of the connecting roller 4 also fits with the film, the cross-section of the connecting roller 4 can be made to contact with the film and the ridge soil. When the vehicle body 1 is traveling, the rear wheel rotates, and the sprocket mechanism 5 can drive the driven shaft 3 and the connecting roller 4 to rotate, 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 film, the staff has already put the vegetable seeds into the inner side of the storage chamber 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 inner side of the sleeve 6 and the punch 10 below due to their own gravity). When the punch 10 punches holes in the film, it can also punch holes in the soil inside the film. When the punch 10 penetrates the film and punches holes in the soil, the seeds are pushed into the soil through the soil. It can make the punch 10 produce a certain resistance force. At this time, the punch 10 at this place moves slightly upward under the micro-elastic action of the telescopic sleeve 801 and the first spring 802. Since the guide plate 1102 is installed on the inner wall of the punch 10 through the movable rod, the limit rod 701 is slidably connected with the first cross bar 7, and the telescopic sleeve 801 is installed at the bottom of the first cross bar 7, when the punch 10 drives the push plate 1001 to move slightly upward, it can drive the guide plate 1102 to rotate around the middle movable rod. When the guide plate 1102 rotates, the adjustment plate 1103 can be pushed downward in cooperation with the second spring 1104. At this time, an inclined guide hole will be formed between the guide plate 1102 and the limit plate 1101, so that a small amount of vegetable seeds inside the punch 10 can be effectively introduced into the inner side of the frame plate 9.

[0026] When the punch 10 moves upward, it will also drive the discharge plates 12 on both sides below to move upward, and under the action of the resistance force of the limit rod 701, the frame plate 9 and the slider 1201, the corresponding discharge plates 12 on the left and right sides are opened to both sides, so that the vegetable seeds on the inner side of the frame plate 9 are scattered on the inner side of the punched holes, thereby completing the sowing of the vegetable seeds. An adjusting rod 803 is threadedly connected above the telescopic sleeve 801. By rotating the adjusting rod 803, the first spring 802 can be squeezed, so that the expansion and contraction amount of the first spring 802 is limited, so that the size of the punch 10, the push plate 1001 and the telescopic sleeve 801 can be adjusted to move slightly upward. Therefore, after the push plate 1001 is adjusted upward, the rotation angle of the guide plate 1102 can also be adjusted, so that the opening size of the guide plate 1102 can be adjusted, and then the size of the discharge port can be effectively adjusted according to different vegetable seed sowing amounts.

[0027] As the vehicle body 1 moves, the connecting roller 4, the sleeve 6 and the punch 10 rotate around the driven shaft 3. When the punch 10 leaves the soil hole, it will be elastically reset through the first spring 802 and the second spring 1104, driving the punch 10, the push plate 1001, the second cross bar 1002, the adjustment plate 1103, the guide plate 1102, the discharge plate 12 and the slider 1201 to reset, thereby realizing the continuous operation of the film punching and sowing.

[0028] In addition, since the sleeve 6 is threadedly connected to the connecting roller 4, it is convenient for the operator to adjust the hole spacing and the drilling depth according to different crops. When the sleeve 6 is disassembled, the holes at the disassembly location can be sealed by the sleeve 6 with a thread on the outside to prevent the vegetable seeds inside the storage chamber 401 from being scattered, thereby completing a series of tasks.
