Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, specifically to a V-groove fertilization, spraying, mulching, and seeding machine. Background Technology

[0002] A seeder is an agricultural machine used to sow seeds into the soil, replacing manual sowing and improving work efficiency and sowing uniformity. For field crops such as corn, mulching sowing technology is often used to conserve water and moisture, increase soil temperature, and suppress weed growth. Among them, V-furrow mulching sowing is a planting method in which mulch film is placed over V-shaped furrows and seeds are sown at the bottom of the furrows, which has a good water collection and drought resistance effect.

[0003] An existing V-groove fertilization, spraying, mulching and seeding machine includes a fertilization device, a spraying device, a V-groove forming device, a mulching device, a mulch covering device, and a hole sowing device. When sowing, the hole sowing device needs to punch holes in the mulch corresponding to the bottom of the V-groove and sow the seeds into the soil.

[0004] In the above-mentioned operation process, the hill-seeding device is a key component for achieving precise sowing. Existing hill-seeding devices mostly use roller-type hill-seeders, with multiple duckbill-type hole-forming devices evenly installed on the circumference of the roller, and a seed-discharging mechanism inside the roller. During operation, the roller contacts the mulch film and passively rotates as the seeder moves forward. During the rotation of the roller, the seed-discharging mechanism delivers seeds one by one to the duckbill-type hole-forming devices. When the duckbill-type hole-forming device rotates to its lowest position, the duckbill opens, and the seed falls into the seed hole, completing one sowing cycle. This structure relies on the friction between the roller and the mulch film for propulsion, requiring no external power input, and has the advantages of simple structure and automatic synchronization of plant spacing and forward speed. During hill-seeding, the seeder needs to perform a seed-collecting process. There are various methods of seed collection, but negative pressure suction seed collection is one of the core technologies in precision hill-seeding devices. Its working principle is to use a fan to generate negative pressure on the suction hole side of the seed-discharging disc, adsorbing and carrying the seeds one by one to the seed-dropping area. Subsequently, by removing the negative pressure or setting positive pressure for seed collection, the seeds fall by their own weight. However, existing roller-type seeders still have the following shortcomings in actual operation: First, the sowing accuracy is not high. Although negative pressure suction can accurately pick up one seed in most cases, sometimes two seeds are picked up, resulting in two or more seeds falling into one seed hole, causing seed waste and difficulty in thinning later; or due to blockage of the seed discharge channel or the seed not entering the seed stalk in time, there are no seeds in the seed hole, affecting crop yield. Second, there is a lack of real-time monitoring and feedback. It is difficult for the driver to detect missed sowing problems in time, and manual replanting can only be done after the operation, which is time-consuming and labor-intensive. Summary of the Invention

[0005] This invention aims to overcome the shortcomings of the prior art and provide a V-groove fertilization, spraying, mulching, and seeding machine.

[0006] Technical Solution: To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A V-groove fertilization, spraying, mulching, and seeding machine includes a frame, a fertilization device, a spraying device, a V-groove forming device, a mulching device, a soil covering device, and a hill-sowing device. The hill-sowing device includes a connecting frame, a seed box, a hollow fixed shaft, a first fan, a second fan, an inner annular baffle with a first notch and a first internal through hole, an outer annular baffle with a first external through hole, a first connecting rigid pipe connecting the first internal through hole and the first external through hole, and wheels. The first fan is connected to a blowing pipe inserted into one end of the fixed shaft, and the second fan is connected to a suction pipe inserted into the other end of the fixed shaft. The wheels include two outer annular plates, two inner annular plates, multiple spokes, and multiple beaks. Each beak includes a mounting plate connecting the two outer annular plates, a seed storage shell fixed to the mounting plate, and a spring-loaded repositioning mechanism. The components include a box cover, an abutment plate connected to the box cover, and a seed inlet pipe fixed to the mounting plate and communicating with the inner space of the seed storage shell. A first drive plate is fixed at the fixed shaft, and the first drive plate can abut against the abutment plate to open the box cover. One of the two inner ring plates has multiple seed storage grooves, each seed storage groove having a ventilation hole. One of the two outer ring plates has multiple seed inlet holes communicating with the seed inlet pipe. The seed box is connected to the seed storage box through a first seed outlet pipe. A ventilation box is fixed at the fixed shaft. The ventilation box has a first ventilation space blown by a first fan and a second ventilation space sucked by a second fan. The ventilation box is connected to a first blower hood facing the first inner through hole through a first blower rigid pipe, and the ventilation box is connected to a first suction hood facing the seed storage box through a first suction rigid pipe.

[0008] Furthermore, the connecting frame is hinged to the machine frame.

[0009] Furthermore, the first gap is located between the seed storage box and the first suction hood.

[0010] Furthermore, the number of seed inlet holes and seed inlet tubes are equal and they correspond one-to-one.

[0011] Furthermore, the seed inlet tube is an L-shaped tube.

[0012] Furthermore, the first blowing rigid pipe is connected to the first ventilation space; the first suction rigid pipe is connected to the second ventilation space.

[0013] Furthermore, the first connecting rigid tube is fixedly connected to the inner annular baffle and the outer annular baffle.

[0014] Furthermore, the spokes are fixedly connected to the inner ring plate and the outer ring plate.

[0015] Furthermore, the duckbill portion is installed between two outer ring plates.

[0016] Furthermore, the seed box, fixed shaft, first fan, second fan, inner annular baffle, and outer annular baffle are all fixed to the connecting frame.

[0017] Furthermore, the seed box has a lid.

[0018] This allows operations such as adding seeds to be performed.

[0019] Furthermore, the cross-section of the seed storage shell is triangular.

[0020] This allows the seed hull to be perforated at the mulch and inserted into the soil.

[0021] Furthermore, the frame is connected to the connecting frame.

[0022] Furthermore, there is a gap between the inner annular baffle and the inner circular plate, the gap being less than 2 mm, preferably less than 1 mm.

[0023] This allows the inner annular baffle and the inner circular plate to be very close together, but with a small gap that allows them to rotate relative to each other.

[0024] Furthermore, the fertilization device is used to dig trenches in the soil and apply base fertilizer; the spraying device is used to spray herbicide onto the soil surface; the V-groove forming device is used to form V-shaped trenches; the mulching device is used to cover the mulch film; the soil covering device is used to cover the soil on both sides of the mulch film to fix the mulch film; and the hole sowing device is used to punch holes in the mulch film corresponding to the bottom of the V-shaped trench and sow seeds into the holes.

[0025] Furthermore, the fertilization device includes a fertilizer furrow opener and a fertilizer discharger. The fertilizer furrow opener is inserted into the soil at a depth greater than that of the hole sowing device, so that the base fertilizer is located 8-10 cm below the seed.

[0026] Furthermore, the spraying device includes a pesticide tank, a pressure pump, and a nozzle, the nozzle being positioned towards the soil surface to form a sealing herbicide film before mulching.

[0027] Furthermore, the V-groove forming device is used to press and form the V-shaped groove.

[0028] Furthermore, the film covering device includes a film hanging frame and a film spreading roller for film covering.

[0029] Furthermore, the soil covering device is used to cover the soil above the two sides of the mulch film to fix the mulch film.

[0030] Furthermore, the first connecting rigid tube is a U-shaped tube.

[0031] Furthermore, multiple seed storage grooves are distributed in a ring with equal spacing, multiple seed inlet holes are distributed in a ring with equal spacing, and multiple duckbill portions are distributed in a ring with equal spacing; the number of seed storage grooves, seed inlet holes, and duckbill portions is equal.

[0032] The seeds in the seed storage groove can enter the duckbill part through the first connecting rigid tube and the seed inlet hole.

[0033] Furthermore, the seed storage box and the first suction hood can have three seed storage grooves.

[0034] Thus, when the seed storage groove passes the seed storage box, the seeds can enter the seed storage groove under the action of the first suction hood, and there is enough time for the seeds to enter the seed storage groove.

[0035] Furthermore, the seed storage box has an open portion that faces the inner circular plate.

[0036] This allows the seeds to pass through the open section and enter the seed storage groove.

[0037] Furthermore, the seed storage box has a feed ramp.

[0038] The inclined plate makes it easier for the seeds in the seed storage box to enter the seed storage groove.

[0039] Furthermore, two protrusions are fixed at the mounting plate, and the box cover is connected to the two protrusions through an elastic reset connection component.

[0040] Furthermore, the mounting plate has a notch through which the abutment plate can pass.

[0041] This makes it easier for the abutment plate to pass through the first and second deflector plates.

[0042] Furthermore, both ends of the fixed shaft are open.

[0043] Furthermore, a circular partition is fixed inside the fixed shaft to divide the space inside the fixed shaft into a first inner shaft space and a second inner shaft space. The ventilation box has an annular partition to divide the space inside the ventilation box into a first ventilation space and a second ventilation space. The fixed shaft has a plurality of first connecting holes connecting the first inner shaft space and the first ventilation space, and a plurality of second connecting holes connecting the second inner shaft space and the second ventilation space.

[0044] Furthermore, the first blowing rigid pipe is connected to the first ventilation space, and the first suction rigid pipe is connected to the second ventilation space.

[0045] Furthermore, the outer annular baffle has a second external through hole, and a second connecting rigid tube is connected between the fixed shaft and the second external through hole, and the second connecting rigid tube communicates with the inner space of the first shaft.

[0046] Furthermore, a second drive plate is fixed at the fixed shaft, and the second drive plate is capable of opening the lid of the duckbill portion located at the second external through hole.

[0047] Thus, the second connecting tube can blow air, and at this time the lid of the duckbill at this position is open, so that if there are debris inside the duckbill, it can be blown away.

[0048] Furthermore, the first drive plate includes a first U-shaped frame connected to a fixed shaft and a first lever plate fixedly connected to the first U-shaped frame.

[0049] Furthermore, the second drive plate includes a second U-shaped frame connected to a fixed shaft and a second lever plate fixedly connected to the second U-shaped frame.

[0050] Furthermore, the end of the first actuating plate is arc-shaped; the end of the second actuating plate is arc-shaped.

[0051] Furthermore, the inner annular baffle also has a second inner through hole, and the ventilation box is connected to a second blower hood facing the second inner through hole via a second blower rigid pipe. The inner annular baffle is fixed with a discharge pipe communicating with the second inner through hole, and the discharge pipe is fixed with a first receiving box. A light emitter and a light receiver are installed in the first receiving box.

[0052] Furthermore, the second air duct is connected to the first ventilation space.

[0053] Therefore, if there are seeds in the seed storage groove corresponding to the second inner through hole, they can be blown into the first receiving box by the air from the second blower hood and detected by the light emitter and light receiver. Of course, during normal operation, there should be no seeds in the seed storage groove at the second inner through hole.

[0054] Furthermore, two light transmitters and two light receivers are installed at the first receiving box.

[0055] Thus, when a seed falls into the first receiving box, the light path is interrupted, allowing it to be detected. Two light emitters and two light receivers can avoid detection blind spots.

[0056] Furthermore, the bottom of the first receiving box has a bottom cover.

[0057] This makes it easy to open the bottom cover for maintenance of the first receiving box.

[0058] Furthermore, the inner annular baffle has a third inner through hole, a fourth inner through hole, and a second notch. A transparent plate is fixed at the fourth inner through hole. A mounting frame is fixed at the inner annular baffle. An image acquisition unit facing the transparent plate is mounted on the mounting frame. A second receiving box is fixed at the connecting frame. The second receiving box has an open end facing the third inner through hole. A hole cover is provided at the third inner through hole. A hole cover driving unit for driving the hole cover is installed inside the second receiving box. The seed box is also connected to a second seed outlet tube with its end facing the second notch. Each seed storage groove can face the second notch. A mounting block is fixed at the inner annular baffle. The mounting block is connected to a lifting plate via an electric lifting rod. The lifting plate is connected to a shielding plate that can block the end of the second seed outlet tube.

[0059] Therefore, the image acquisition unit can determine whether there are two seeds in the seed storage groove based on the acquired image. If so, when the seed storage groove reaches the hole cover, the two seeds can be blown to the second receiving box. When the seed storage groove reaches the second notch, the baffle plate can be raised so that new seeds can enter the seed storage groove.

[0060] Furthermore, the seeds are arranged in a row within the second seed tube.

[0061] Therefore, due to the setting of the inner diameter of the second seed outlet tube, the seeds are distributed in a row, so that one seed falls from the second seed outlet tube into the seed storage groove at a time.

[0062] Furthermore, both the first and second seed-producing tubes are rigid tubes.

[0063] Furthermore, the mounting bracket is a U-shaped bracket.

[0064] Furthermore, both the first and second seed-producing tubes are rigid tubes.

[0065] Furthermore, the ventilation box is connected to a third air blower hood facing the third inner through hole via a third air blower rigid pipe, and the third air blower rigid pipe is connected to the first ventilation space.

[0066] Furthermore, the ventilation box is connected to a second suction hood facing the second notch via a second suction hard pipe, and the second suction hard pipe is in communication with the second ventilation space.

[0067] Furthermore, the second notch is a vertical strip-shaped notch.

[0068] Furthermore, the side of the shield facing the end of the second seed outlet tube is inclined.

[0069] Therefore, when the shielding plate descends, it is easier to block the seeds in the second seed outlet tube without damaging the seeds.

[0070] Furthermore, the hole cover intersects with the third inner through hole, the hole cover is fixed with a hinge plate, the second receiving box is fixed with a first hinge seat, the first hinge seat is connected to a second hinge seat through an electric telescopic rod, and the second hinge seat is hinged to the hinge plate.

[0071] Furthermore, the third inner through hole includes a circular hole and a protruding hole communicating with the circular hole, and the hole cover includes a circular plate and a protruding block connected to the circular plate, the protruding block being hinged to the protruding hole.

[0072] Furthermore, the second receiving box has a door.

[0073] This allows the box door to be opened and the second receiving box to be cleaned.

[0074] Furthermore, the connecting frame includes a connecting frame body, two straight connecting plates connecting the seed box and the connecting frame body, and two L-shaped connecting plates connecting the inner annular baffle and the connecting frame body; each inner annular plate is connected to the fixed shaft by a bearing.

[0075] Furthermore, the second receiving box is fixedly connected to one of the L-shaped connecting plates.

[0076] Furthermore, the outer annular baffle is fixedly connected to the connecting frame body through multiple first connecting plates.

[0077] Furthermore, the first receiving box is fixedly connected to the connecting frame body through multiple second connecting plates.

[0078] Furthermore, both the first fan and the second fan are fixed to the connecting frame body.

[0143] The seeding device, fertilization device, spraying device, V-groove forming device, mulching device, soil covering device, and hill seeding device of this application can respectively realize fertilization, spraying, V-groove forming, mulching, soil covering, and hill seeding, thereby achieving automated seeding. Furthermore, the hill seeding device of this application can avoid the situation where no seeds are sown after the mulching hole, and can also avoid the situation where two seeds are sown in one hole. The specific working principle is as follows:

[0144] Under the action of the traction device, the traveling wheels move, thus rotating. Because the inner ring plate 3.1 rotates, the seed storage groove 3.1.1 at the inner ring plate 3.1 can sequentially pass through the seed storage box 2.3, the fourth inner through hole, the third inner through hole 4.1.3, the second notch 4.1.4, the first inner through hole 4.1.5, and the second inner through hole 4.1.6. Since the inner ring plate 3.1 and the outer ring plate 3.2 rotate synchronously, the seed inlets 3.2.1 at the outer ring plate 3.2 can pass through... The first external through hole 4.2.1 and the second external through hole 4.2.2 are connected. When the duckbill part passes through the second external through hole 4.2.2, the abutment plate 3.4.4 can be abutted by the second lever plate 5.4, thereby opening the lid 3.4.3 of the duckbill part (at this time, the second connecting rigid tube 8.2 can blow air, so that if there are debris, such as mud or weeds, in the duckbill part, they can be blown away in time). After passing through the second lever plate 5.4, the lid 3.4.3 can be reset and closed under the action of the elastic reset hinge component. Similarly, when passing through the first external through hole 4.2.1, the abutment plate 3.4.4 can be abutted by the first lever plate 5.2, thereby opening the lid 3.4.3 of the duckbill part. After passing through the first lever plate 5.2, the lid 3.4.3 can be reset and closed under the action of the elastic reset hinge component. The specific engineering process is as follows: When the seed storage groove 3.1.1 passes through the seed storage box 2.3, under the negative pressure suction of the first suction hood 8.3.1, the seeds in the seed storage box 2.3 will enter the seed storage groove 3.1.1. As the inner ring plate 3.1 rotates, the seed storage groove 3.1.1 will rotate with the seeds (due to the obstruction of the inner ring baffle 4.1, the seeds will not fall out of the seed storage groove 3.1.1). When the seed storage groove 3.1.1 containing seeds passes through the fourth inner through hole, the image acquired by the image acquisition unit can determine whether there is one seed, two seeds, or no seeds in the seed storage groove 3.1.1 (normally, it is desirable for the seed storage groove to contain one seed).

[0145] When a seed is present, no operation is performed at the third inner through hole 4.1.3 and the second notch 4.1.4. When the seed reaches the first inner through hole 4.1.5, it is blown by the first blower hood 8.5, so that the seed enters the first connecting rigid tube 8.1 and enters the duckbill part. When the duckbill part reaches the first drive plate, it is just in the sowing position below, so the cover 3.4.3 of the duckbill part opens, so that sowing is carried out. After sowing is completed, the cover 3.4.3 is reset. When two seeds are stored, the seed storage groove 3.1.1 can open the cover 6.3.2 when it passes through the third inner through hole 4.1.3, and the third blower hood 8.7.1 can blow both seeds into the second receiving box 6.3, so that the seed storage groove 3.1.1 is empty. Then, when the seed storage groove 3.1.1 passes through the second notch 4.1.4, the baffle 6.4.3 can rise, and under the negative pressure suction of the second suction hood 8.4.1, the seeds in the second seed outlet tube 2.2 (where the seeds are arranged in a row) can enter the seed storage groove 3.1.1, so that the seed storage groove 3.1.1 contains one seed at this time, so that sowing can be performed when it reaches the first inner through hole 4.1.5. When there are no seeds in the seed storage groove 3.1.1, no operation is performed when the seed storage groove 3.1.1 passes through the third inner through hole 4.1.3. When it passes through the second notch 4.1.4, the baffle plate 6.4.3 can rise, and under the action of the second suction hood 8.4.1, the seeds at the second seed outlet tube 2.2 can enter the seed storage groove 3.1.1. At this time, there is one seed in the seed storage groove 3.1.1, so that sowing can be performed when it reaches the first inner through hole 4.1.5.

[0146] Furthermore, since the seeds in the seed storage groove 3.1.1 have already passed through the first inner through hole 4.1.5, and the seeds were blown away by the first blower hood 8.5.1 at the first inner through hole 4.1.5, when they subsequently pass through the second inner through hole 4.1.6, although the second blower hood 8.6.1 also blows air, theoretically no seeds will fall into the first receiving box 6.2 because there are no seeds in the seed storage groove 3.1.1. Therefore, the light path of the light emitter 6.2.1 will not be cut off. When a seed is detected cutting off the light path of the light emitter, it indicates that the seeds in the seed storage groove 3.1.1 were not blown into the first connecting rigid tube 8.1 when passing through the first inner through hole 4.1.5, indicating a malfunction, which can remind us to maintain it in time.

[0147] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
