Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bean seed reseeding equipment, in particular to a multifunctional bean seed reseeding vehicle and application thereof. BACKGROUND

[0002] During the breeding and planting of soybean, mung bean and other legume crops, the seeds are first planted in the ground, and the seedlings are then transplanted after the seeds germinate. However, due to the quality of the seeds, some seeds in the planting holes may not germinate, so it is necessary to reseed the planting holes that do not germinate. The traditional reseeding method is to use a shovel or a hoe to dig the planting hole, and then put the seeds into the hole. However, using a shovel or a hoe requires the person to bend over for a long time, which greatly consumes the person's physical strength and causes damage to the waist. Therefore, a more labor-saving tool is needed.

[0003] The paper towel germination method is a plant seedling raising technology that cultivates seeds on paper towels to provide seeds with appropriate moisture, nutrients and temperature to promote seed germination. This method is compatible with the reseeding process of bean seeds and can make the reseeded bean seeds have the same growth progress as the first planted bean seeds. The advantage of this method is that if controlled properly, the air permeability of the paper towel is better than that of the soil, and the humidity is greater. Compared with the complex soil environment of disease, insects and fungi, the paper towel is more conducive to seed germination. Currently, the paper towel germination method commonly uses ordinary paper towels for germination operation in the room. The paper towel only plays a role in germination, and if the seeds germinate, a second planting is needed, so it is not suitable for large-scale planting. SUMMARY

[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] Example

[0041] like Figure 1 and Figure 2 As shown, a multi-functional soybean seed replanting vehicle includes a frame 100, a replanting mechanism 300, an irrigation mechanism 300, and a fertilization mechanism 200. Wheels 101 are arranged around the frame 100. The replanting mechanism, irrigation mechanism 300, and fertilization mechanism 200 are arranged sequentially from front to back on top of the frame 100. A camera module, a seed pit covering device, and a ditching mechanism 104 are arranged at the bottom of the frame 100. A fertilizer ditch covering device is arranged at the rear of the frame 100. The camera module is used to capture images of the bottom of the frame 100, and the captured images can be used to determine whether seedlings have emerged at the seed pit 110.

[0042] like Figure 4As shown, the ditch covering device is located at the rear of the frame 100, and includes a connecting frame and two ditch covering discs 102. The planting pit covering device is located in the middle of the frame 100, and includes a movable connecting rod and two planting pit covering discs 103. The center lines of the two ditch covering discs 102 are parallel to the forward direction of the frame 100, and the center lines of the two planting pit covering discs 103 are perpendicular to the forward direction of the frame 100. The ditch covering device is used to restore the ditch 109 broken by the ditching mechanism 104, and its direction of movement is consistent with the direction of the ditch 109, i.e., the direction of movement of the frame 100. The planting pit covering device is used to restore the planting pit 110 broken by the hole-opening device 500, and therefore its direction of movement is perpendicular to the direction of movement of the frame 100. The planting pit covering device is connected to the frame 100 through an extendable and rotatable movable connecting rod, thereby better performing the covering work. The specific structure of the movable linkage can refer to existing linkage structures, and can be a linear electric push rod, etc., which is fixed in the frame through connectors.

[0043] like Figure 5 As shown, the ditching mechanism 104 is located between the seed pit coverer and the fertilizer ditch coverer. The ditching mechanism 104 includes a plow head 105, a telescopic groove 107, and a telescopic connecting rod 106. The telescopic groove 107 is fixed to the bottom of the frame 100. The top of the plow head 105 is slidably connected to the telescopic groove 107, and the bottom of the plow head 105 is bent towards the front of the machine. The outer side of the telescopic groove 107 is connected to the middle of the plow head 105 via the hinged telescopic connecting rod 106. The centerline of the plow head 105 and the fertilizer ditch cover plate 102 are on the same straight line. A lifting motor is installed inside the frame 100 to pull the plow head 105 up and down in the telescopic groove 107. During this process, the telescopic connecting rod 106 maintains the stability of the plow head 105. The ditching mechanism 104 is lowered before the machine starts operating and raised after operation.

[0044] like Figure 6 As shown, the replanting mechanism includes a protective shell 400, an opening device 500, a cutting device 800, a paper feeding device 600, a paper clamping device 700, and a paper storage device 900. The protective shell 400 includes a left base 402, a right base 403, and a top protective cover 401. The left base 402 and the right base 403 are respectively located on the front sides of the frame 100. The top protective cover 401 is fixed above the left base 402 and the right base 403. The paper storage device 900 is located between the left base 402 and the right base 403. A working groove 108 is opened on the frame 100 in front of the paper storage device 900. The cutting device 800, the opening device 500, and the paper feeding device 600 are all located in the working groove 108.

[0045] The paper storage device 900 includes a right-angle fixing plate 901, a paper roll fixing seat 902, and a paper sheet pressing plate 903. The right-angle fixing plate 901 is fixed on the frame 100 and located between the left base 402 and the right base 403. The paper roll fixing seat 902 is fixed on the vertical surface of the right-angle fixing plate 901. The paper sheet pressing plate 903 is disposed above the paper roll fixing seat 902, and a biodegradable paper towel roll 904 is wound on the paper roll fixing seat 902. The paper sheet pressing plate 903 is used to prevent the biodegradable paper towel from curling up and forces the biodegradable paper towel to hang down.

[0046] The paper clamping device 700 is adjacent to the paper storage device 900. The paper clamping device 700 includes a paper clamping linear guide rail 701, a paper clamping ball screw guide rail 702, a paper clamping upper plate 703, and a paper clamping lower plate 704. The paper clamping linear guide rail 701 is fixed to the inner side of the right base 403. The top end of the paper clamping ball screw guide rail 702 is connected to the slider of the paper clamping linear guide rail 701. The paper clamping upper plate 703 is fixed on the slider of the paper clamping ball screw guide rail 702. The paper clamping lower plate 704 is fixed to the bottom of the paper clamping ball screw guide rail 702. The bottom surface of the paper clamping upper plate 703 and the top surface of the paper clamping lower plate 704 are both provided with serrated stripes to prevent the paper towel from slipping. The paper clamping upper plate 703 moves along the paper clamping ball screw guide rail 702. When the paper clamping upper plate 703 moves to the bottom, it is pressed against the paper clamping lower plate 704, clamping the biodegradable paper towel in the middle. Then, the paper clamping linear guide 701 synchronously pulls the paper clamping upper plate 703 and the paper clamping lower plate 704 to send the paper towel to the top of the paper feeding device 600.

[0047] like Figure 7 As shown, the cutting device 800 is located between the paper clamping device 700 and the paper feeding device 600, and is used to cut the paper towel. The cutting device 800 includes a cutting drive motor 801, a fixed base plate 804, an active ratchet, a passive ratchet, an upper scissor blade 802, a lower scissor blade 803, and traction links. The cutting drive motor 801 is fixed to the upper front end of the fixed base plate 804, which is fixed to the frame 100. Both the active and passive ratchet are rotatably connected to the back of the fixed base plate 804. The output shaft of the cutting drive motor 801 passes through the fixed base plate 804 and is linked with the active ratchet. The ends of the active and passive ratchet near the middle of the fixed base plate 804 are engaged by several teeth. The other end of the active ratchet extends outward and is hinged to the bladeless end of the upper scissor blade 802. The other end of the passive ratchet extends outward and is hinged to the bladeless end of the lower scissor blade 803. The corners of the upper and lower scissor blades 802 and 803 are also hinged to the fixed base plate 804 by several traction links. The blades of the upper scissor blade 802 and the lower scissor blade 803 are arranged opposite each other. When the cutting drive motor 801 starts, the active ratchet drives the passive ratchet to rotate, and the upper scissor blade 802 and the lower scissor blade 803 approach and intersect, cutting the paper towel through the blades.

[0048] The paper feeding device 600 includes a paper feeding ball screw guide rail 601, a movable base plate 602, two rotating toothed plates 603, and two valve plates 604. The paper feeding ball screw guide rail 601 is fixed to the inner side of the right base 403. The movable base plate 602 is fixedly connected to the slider of the paper feeding ball screw guide rail 601. The rotating toothed plates 603 are rotatably connected to the movable base plate 602. A paper feeding valve motor is provided on the back of the movable base plate 602, and the paper feeding valve motor is linked with the rotating toothed plates 603. The two rotating toothed plates 603 mesh with each other. The valve plates 604 are fixedly connected to the rotating toothed plates 603. A protruding triangular block 605 is provided on the outer corner of the valve plate 604 to prevent small pieces of paper from falling off the valve plate 604. As the movable substrate 602 moves along the paper feeding ball screw guide rail 601, the paper feeding valve motor on the back of the movable substrate 602 is activated, causing the moving toothed plate to rotate, thereby causing the valve plate 604 to flip open and drop the paper towel.

[0049] like Figure 10 As shown, the hole-opening device 500 includes a hole-opening linear guide rail 502, a first connecting plate 504, a first linear electric push rod 503, and a hole-opening drill bit 501. The two ends of the hole-opening linear guide rail 502 are fixedly connected to the left base 402 and the right base 403, respectively. One end of the first connecting plate 504 is fixedly connected to the slider of the hole-opening linear guide rail 502, and the other end of the first connecting plate 504 is fixedly connected to the top end of the first linear electric push rod 503. The first linear electric push rod 503 passes through the hole-opening translation groove on the frame 100, and the hole-opening translation groove is connected to the working groove 108. The end of the first linear electric push rod 503 is connected to the hole-opening drill bit 501, and a spiral soil-moving groove 505 is provided on the hole-opening drill bit 501. After the hole-opening device 500 is activated, the first connecting plate 504 and the first linear electric push rod 503 slide along the hole-opening linear guide rail 502 across the hole-opening translation groove, moving from the edge to the hole-opening position. Then, the first linear electric push rod 503 is activated, causing the hole-opening drill bit 501 to descend to the hole-opening height. As the hole-opening drill bit 501 rotates, it discharges soil through the spirally rotating soil-moving trough 505, forming the planting pit 110. After the hole-opening is completed, the hole-opening drill bit 501 needs to return to its original position.

[0050] like Figure 8 and Figure 9 As shown, the irrigation mechanism 300 and the fertilization mechanism 200 are linked. The irrigation mechanism 300 includes a water tank 301, a water tank base 308, and a water outlet pipe. The water tank 301 is fixedly connected to the center of the top surface of the frame 100 via the water tank base 308. The top of the water tank base 308 is provided with a grooved top rod 303, and the grooved top rod 303 is provided with several semi-circular drainage grooves 307. The size of the drainage grooves 307 is adapted to the water outlet 302 of the water tank 301. The bottom of the water tank base 308 is connected to the water outlet pipe, which passes through the irrigation inlet 305 located on the bottom surface of the frame 100.

[0051] The grooved top rod 303 is linked to the first transmission rod 304, which passes through the side of the water tank base 308. The other end of the first transmission rod 304 is linked to the first transmission gear 309. Several partition plates 306 are also provided at the bottom of the interior of the water tank base 308. When the first transmission gear 309 rotates, the first transmission rod 304 drives the grooved top rod 303 to rotate. The drain trough 307 periodically contacts the water outlet 302 and collects a fixed amount of water. When the drain trough 307 flips, the water is irrigated into the seed pit 110 through the water outlet pipe. The partition plates 306 make the water distribution more even. Therefore, the grooved top rod 303 ensures that each seed pit 110 is filled with an appropriate amount of water, preventing excessive watering that could cause the seeds to rot.

[0052] like Figure 3 As shown, the fertilization mechanism 200 includes a fertilizer box 202, a feeding pipe, and a screw conveyor 203. Two cylindrical fertilizer troughs 204 are arranged side-by-side at the bottom of the fertilizer box 202. The screw conveyor 203 is located within the fertilizer troughs 204. The bottoms of the two fertilizer troughs 204 are connected to the top of the feeding pipe. The bottom end of the feeding pipe passes downwards through the bottom surface of the frame 100. The screw conveyor 203 is linked with a second transmission rod 206 that passes through the fertilizer troughs 204 from the side. The other end of the first transmission rod 304 is linked with a second transmission gear 207. The first transmission gear 309 and the second transmission gear 207 are linked via a transmission chain 205. The second transmission gear 207 and the first transmission gear 309 operate synchronously. While watering the planting pit 110, the screw conveyor 203 rotates to deliver a fixed amount of fertilizer into the feeding pipe each time.

[0053] An application of a multifunctional soybean seed replanting vehicle proposes a method for germinating soybean seeds using biodegradable paper towels, the steps of which are as follows:

[0054] S1. Seedling identification: The camera module collects image information of the current planting point and analyzes the image to determine whether the planting point has seedlings. If there are seedlings, no replanting is required. After moving forward a certain distance, the center of the soil covering device in the planting pit is aligned with the planting point, and fertilization and irrigation are carried out at the same time. If no seedlings are identified, replanting is carried out. Fertilization and irrigation are carried out again after replanting.

[0055] S2. Four-corner fertilization and irrigation: Before driving, lower the ditching mechanism 104 so that the plow head 105 contacts the soil. During driving, open two fertilization furrows. Fertilize and irrigate once at every planting point. The irrigation location is the center of the planting point. The location corresponding to the end of the discharge pipe 201 of the fertilization mechanism 200 is fertilizer point 111. Fertilizer points 111 are located at the four corners of a rectangle centered on the planting point. Figure 11 As shown, after fertilization, the fertilization trench covering device located at the rear end of the frame 100 covers the trench with soil.

[0056] Four-corner fertilization is more cost-effective than strip fertilization and has a higher fertilizer utilization rate. Compared with hole fertilization, it can prevent seedling burn, and compared with ring fertilization, it is simpler. Adjacent planting points share two fertilizer points 111, which further improves fertilizer utilization and reduces the complexity of vehicle frame 100 movement.

[0057] S3. Replanting and hole making: The hole making device 500 is activated, the first linear electric push rod 503 extends downward, and the hole making drill bit 501 makes a seed pit 110 at the seed point. After the hole is made, the hole making linear guide rail 502 is activated to move the hole making drill bit 501 away to avoid blocking the paper feeding device 600.

[0058] S4. Paper feeding: The paper clamping device 700 is activated. The upper paper clamping plate 703 slides down along the paper clamping ball screw guide rail 702. The upper paper clamping plate 703 and the lower paper clamping plate 704 clamp the end of the biodegradable tissue roll 904, and then slide along the paper clamping linear guide rail 701 to above the paper feeding device 600, placing it above the valve plate 604. The biodegradable tissue is made of polyvinyl alcohol (PVA). Polyvinyl alcohol is a water-soluble polymer with relatively stable chemical properties. Its molecular chain contains a large number of side hydroxyl groups, thus exhibiting good hydrophilicity. It also possesses good mechanical properties, heat resistance, resistance to organic solvents, resistance to organic pollution, and good film-forming properties. By adjusting its purity and adding crosslinking agents or changing the thickness, the hydrolysis time can be controlled to match the germination time of the soybean seeds. Figure 12 As shown.

[0059] S5. Paper cutting: The cutting device 800 is activated, and the upper scissor blade 802 and the lower scissor blade 803 meet to cut the biodegradable paper towel from one side of the valve plate 604.

[0060] S6. Paper feeding: The paper feeding device 600 is started. The valve plate 604 moves down along the paper feeding ball screw guide rail 601 to a position 20cm above the seed pit 110. The valve plate 604 flips over, allowing the biodegradable paper towel to fall naturally into the seed pit 110.

[0061] S7. Cover with soil. Move the frame 100 forward so that the soil covering device for the planting pit is on the same straight line as the planting pit 110. Then carry out the fertilization and irrigation operation in S2. Then the soil covering device for the planting pit 110 will cover with soil to complete the replanting.

[0062] Therefore, the present invention provides a multifunctional soybean seed replanting vehicle and its application using the above-mentioned structure and steps. It identifies the seedling status through a camera module, performs seedling replanting through a replanting mechanism, irrigates the seedlings through an irrigation mechanism 300, applies fertilizer to the seedlings at four corners along the fertilizer furrow 109 through a fertilization mechanism 200, and uses biodegradable paper towels for outdoor germination. This enables the entire process of soybean seed replanting to be completed, thereby improving replanting efficiency.

[0063] The use of biodegradable paper towels for germination has the following beneficial effects:

[0064] (1) Unlike traditional indoor germination, outdoor germination is used, eliminating the need for secondary planting and saving manpower;

[0065] (2) Water retention: Biodegradable paper towels have good water retention properties, which can lock in a large amount of water and improve water utilization, thereby achieving the goal of saving water. Paper towels provide seeds with a sufficiently moist germination environment, improving the germination success rate.

[0066] (3) Insect prevention: The biodegradable paper towel is recessed inward in the seed pit 110 to provide a protective layer for the seeds and can prevent insect bites.

[0067] (4) Heat preservation: biodegradable paper towels generate heat when hydrolyzed, and seeds also generate heat when germinating. Paper towels can prevent heat from being lost too quickly, thus achieving the effect of heat preservation, which is beneficial to seed germination.

[0068] (5) Environmentally friendly, biodegradable paper towels will not affect the subsequent growth of plants after degradation. Polyvinyl alcohol only produces water and carbon dioxide after hydrolysis, which will not only not harm the environment, but also benefit plant growth.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
