Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, in particular to a mulching and seeding machine. BACKGROUND

[0002] In agricultural seeding operations, mulching and seeding is an important technical means to improve crop emergence rate, conserve soil moisture, and inhibit weed growth, and is widely used in the planting process of corn, cotton, peanuts and other crops. However, the existing mulching and seeding equipment still has many problems to be solved in practical application: On the one hand, the seeding effect of traditional seeding machines is not good, and it is difficult to meet the demand of fine planting. The connection of ditching, seeding and soil closing process of some seeding machines is not close enough, and the ditching depth is inconsistent and the seeding amount is uneven, which leads to unbalanced distribution of seeds in the soil, uneven growth of crops after emergence, and directly affects the subsequent yield. Especially for crops using point planting mode, the point planting precision of existing seeding mechanism is insufficient, and the seeds are prone to miss planting and over-planting, and the position of the seeds in the seeding ditch cannot be accurately controlled, further reducing the seeding quality. On the other hand, in the existing mulching and seeding operation, the cutting process of the mulch film depends on manual operation, which is low in efficiency and high in labor intensity. After completing the mulching and seeding of a section of area, the operator needs to manually cut the mulch film and then perform the next operation, which not only interrupts the seeding process, resulting in a significant reduction in operation efficiency, but also increases labor costs. At the same time, the cut flatness of manual film cutting is poor, and problems such as film tearing and inconsistent edge retention are prone to occur, affecting the covering effect of the subsequent mulch film, and even because of the loosening of the film at the cut, the soil moisture conservation and weed suppression functions are lost. In addition, during the manual film cutting process, the operator needs to move synchronously with the seeding machine, which has certain safety hazards, and the operation quality is greatly affected by human factors, making it difficult to ensure consistency. Therefore, it is a key requirement to develop a mulching and seeding machine that can realize precise seeding and automatic mulching and cutting, and efficient connection of each process, to solve the technical problems of the existing technology and improve the efficiency and quality of agricultural seeding operations.

[0025] Embodiment 2: Embodiment 2 is based on embodiment 1: As shown in Figures 1 to 8 The furrowing mechanism 21 comprises a furrowing support column 211 and a furrowing disc 212, the furrowing support column 211 is arranged on one side of the main frame 1 through a connecting assembly 213; and the bottom end of the furrowing support column 211 is rotatably connected with the furrowing disc 212.

[0026] The furrowing support column 211 provides stable support for the furrowing disc 212, avoiding deviation of the furrowing depth and width caused by mechanism shaking during furrowing; the rotatable furrowing disc 212 can reduce frictional resistance by self-rotation when contacting with the soil, reducing the wear of the disc by the soil, while ensuring the continuity of the furrowing track, avoiding the phenomenon of “jumping trench” and “broken trench”, and ensuring the regularity of the seeding trench shape.

[0027] The front end of the furrow disc 212 is obliquely arranged towards the main frame 1, so that the disc body can cut into the soil more smoothly when advancing, and the soil is reduced to accumulate on both sides of the disc body, and the soil is guided to be turned away from the center of the seeding furrow, so that the seeding furrow with uniform depth and flat wall is formed, which lays a good foundation for subsequent seed filling and film laying, and avoids the deviation of seed sowing position or the incompatibility of film covering caused by irregular furrow type.

[0028] As an optional embodiment, the connecting assembly 213 includes a connecting back plate 2131, a U-shaped connecting piece 2132, a threaded connecting piece 2133, and a first threaded locking piece 2134.

[0029] The connecting back plate 2131 is provided with a mounting hole, the U-shaped connecting piece 2132 is sleeved on the cross beam 11 of the main frame 1, and the end portion penetrates through the mounting hole and is connected with the corresponding threaded connecting piece 2133; the U-shaped connecting piece 2132 and the threaded connecting piece 2133 are matched with each other, so that the connecting back plate 2131 can be quickly fixed on the main frame 1, and the equipment parts can be conveniently replaced and maintained; at the same time, the threaded connection structure is adopted, the connection is firm, the furrowing mechanism 21 is prevented from loosening due to vibration during furrowing, and the working effect is ensured.

[0030] The connecting back plate 2131 is provided with a first mounting slot in the vertical direction, and the top end of the furrowing support column 211 penetrates through the first mounting slot; the first threaded locking piece 2134 is threadedly connected on the connecting back plate 2131, and the end portion can be inserted into the first mounting slot and connected with the furrowing support column 211. In this way, on the one hand, the relative position of the furrowing support column 211 can be effectively locked to prevent it from rotating, thereby ensuring the furrowing effect; on the other hand, during actual use, the user can adjust the relative position of the furrowing support column 211 relative to the first mounting slot according to actual needs to realize the adjustment of the furrowing depth, so that the device versatility can be improved.

[0031] Specifically, the furrowing support column 211 is made of a square tube, and the back surface of the connecting back plate 2131 is fixedly provided with a square tube sleeve, and the inner cavity of the square tube sleeve forms the first mounting slot; the connecting back plate 2131 is made of a steel plate punched and cast, and the positions close to the four corners are provided with clamping jaws which can be clamped on the cross beam 11 of the main frame 1.

[0032] As an optional embodiment, the soil mixing mechanism 23 includes a primary soil mixing assembly 231, and the primary soil mixing assembly 231 includes a first pressing arm 2311, a first soil mixing support column 2312, and a first soil mixing disc 2313.

[0033] The first end of the first pressing arm 2311 is arranged at one side of the main frame 1, the second end of the first pressing arm 2311 is provided with a second mounting slot in the vertical direction, the first pressing arm 2311 is provided with a first compression spring 2315; in the process of soil mixing, the soil entering pressure can be adaptively adjusted.

[0034] The top end of the first soil mixing support column 2312 penetrates the second mounting slot, the first pressing arm 2311 is threadedly connected with a second threaded locking piece, the end of the second threaded locking piece can be inserted into the second mounting slot and connected with the first soil mixing support column 2312; in the actual application process, the user can adjust the relative position of the first soil mixing support column 2312 by loosening or tightening the second threaded locking piece, so as to realize the adjustment of the soil mixing depth and intensity.

[0035] The first soil mixing disc 2313 is rotatably arranged at the bottom end of the first soil mixing support column 2312 through a first bearing assembly 2314, a skeleton oil seal is additionally arranged in the bearing chamber of the first bearing assembly 2314, a rubber dustproof pad, a flat pad and a compression spring are additionally arranged outside the bearing chamber of the first bearing assembly 2314, which can effectively guarantee the sealing effect, avoid the overflow of lubricating oil, and prevent the entry of external dust.

[0036] The front end of the first soil mixing disc 2313 is arranged in an inclined manner away from the main frame 1, which can expand the soil collection range and improve the soil mixing efficiency.

[0037] As an optional embodiment, the soil mixing mechanism 23 comprises a secondary soil mixing assembly 232, the secondary soil mixing assembly 232 comprises a second pressing arm 2321, a second soil mixing support column 2322 and a second soil mixing disc 2323.

[0038] The first end of the second pressing arm 2321 is arranged at one side of the main frame 1, the second end of the second pressing arm 2321 is provided with a third mounting slot in the vertical direction, the second pressing arm 2321 is provided with a second compression spring 2325, the top end of the second soil mixing support column 2322 penetrates the third mounting slot, the second pressing arm 2321 is threadedly connected with a third threaded locking piece, the end of the third threaded locking piece can be inserted into the third mounting slot and connected with the second soil mixing support column 2322; the second soil mixing disc 2323 is rotatably arranged at the bottom end of the second soil mixing support column 2322 through a second bearing assembly 2324, the front end of the second soil mixing disc 2323 is arranged in an inclined manner away from the main frame 1, the secondary soil mixing assembly 232 is similar to the primary soil mixing assembly 231 in structure and effect.

[0039] The diameter of the second soil mixing plate 2323 is smaller than that of the first soil mixing plate 2313. The smaller diameter of the second soil mixing plate 2323 concentrates the pressure on the soil, which can avoid the problem of "root hanging" caused by the loose soil after the first soil mixing, and ensure that the seeds are in a compact and breathable soil environment, reducing the risk of the germination rate being affected by the soil structure. The combination of the two soil mixing makes the sowing furrow filling more even and sufficient.

[0040] As an optional implementation, the sowing mechanism 22 includes a seed metering container 222 and a seed metering scoop wheel 223. The seed metering container 222 is fixedly mounted on the main frame 1 and is used to hold the seeds to be filled. The seed metering scoop wheel 223 is rotatably mounted on the main frame 1. The seed metering container 222 is connected to the seed inlet of the seed metering scoop wheel 223. The seed metering scoop wheel 223 is provided with multiple seed metering ports along the circumference. The number of seeding beaks 221 is the same as the number of seed metering ports. The seeding beaks 221 are positioned at positions corresponding to the seed metering ports.

[0041] The seed metering container 222 and the seed metering scoop wheel 223 work together to form a scoop wheel seed metering device. Together with the spot-sowing duckbill 221, it can effectively ensure quantitative and uniform seed sowing, while also ensuring the continuity and stability of sowing.

[0042] As an optional implementation, the seeding spout 221 includes a seeding spout body 2211 and a flip-up seeding spout cover 2212. The seeding spout body 2211 is fixedly installed on the peripheral wall of the seed metering wheel 223. The seeding spout body 2211 is provided with a seeding channel, and the inlet end of the seeding channel is connected to the corresponding seed metering port. The flip-up seeding spout cover 2212 is installed on the seeding spout body 2211 and can be flipped to cover the outlet end of the seeding channel.

[0043] In practical applications, when the duckbill inlet 2211 is not yet in the soil, the duckbill cover 2212 is flipped over to cover the outlet end of the sowing channel to prevent the seeds from falling out prematurely; when the duckbill inlet 2211 passes through the mulch film and is inserted into the soil, the duckbill cover 2212 is flipped over to open the outlet end of the sowing channel, and the seeds fall into the sowing furrow along the channel.

[0044] As an optional implementation, the seeding spout 221 includes an elastic element 2213, which is a spring. The flip-up spout cover 2212 includes a first cover and a second cover connected together. The first cover can be flipped to cover the outlet end of the seeding channel. The two ends of the elastic element 2213 are respectively connected to the outer wall of the second cover and the seeding wheel 223.

[0045] After the duckbill insert 2211 leaves the soil, the rebound force of the elastic element 2213 can pull the second cover, causing the first cover to quickly close the seeding channel outlet, preventing seeds from scattering due to the duckbill cover not being reset in time; at the same time, the pre-tightening force of the elastic element 2213 can make the first cover fit tightly against the channel outlet, improving the sealing effect and preventing seeds from leaking out during transportation.

[0046] The elastic element 2213 has a certain elastic deformation capacity. When the duckbill inlet body enters the soil and the duckbill cover is overturned due to soil resistance, the elastic element 2213 can buffer the impact force during the overturning process, reduce the mechanical wear between the overturned duckbill cover 2212 and the duckbill inlet body 2211, and extend the service life of the component. At the same time, the buffering effect can prevent the overturned duckbill cover 2212 from deforming due to impact, and ensure the long-term stability of the sealing performance of the channel outlet.

[0047] As an optional implementation, the seed-sowing duckbill 221 adopts a duckbill-like structure, which is formed by die stamping. Its sides are high and the middle is low, which can enable the seeds to enter the center of the membrane hole at the lowest point, resulting in a significant seed-sowing effect.

[0048] As an optional implementation, the film laying mechanism 31 includes a film laying roller, which is rotatably mounted on the main frame 1 and has a film roll on it; in actual application, the seeder moves and the film laying roller rotates to unfold and lay the mulch film.

[0049] As an optional implementation, the film cutting mechanism 32 includes a film cutting telescopic assembly 321 and a film cutting shovel 322. The film cutting telescopic assembly 321 is a hydraulic telescopic assembly, which is mounted on the main frame 1 and its oil circuit is connected to a hydraulic distributor.

[0050] The film cutting shovel 322 includes a shovel body 3221 and a connecting rod 3222 disposed on the shovel body 3221. The connecting rod 3222 is provided with a first connecting end 3223 and a second connecting end 3224. The first connecting end 3223 is hingedly disposed on the main frame 1. The telescopic end of the film cutting telescopic assembly 321 is hingedly connected to the second connecting end 3224.

[0051] When cutting the film, the telescopic end of the film cutting telescopic component 321 extends and retracts, causing the film cutting shovel 322 to swing, thereby cutting the film.

[0052] The film cutting telescopic component 321 and the film cutting shovel 322 work together to replace manual film cutting with mechanical film cutting. This not only ensures the cutting position and the flatness of the cut, resulting in a significant film cutting effect, but also greatly reduces the intensity of manual labor and improves work efficiency.
