Description

Technical Field

[0001] The invention relates to the technical field of sowing and fertilizing machinery, in particular to an agricultural sowing and fertilizing machinery. Background Art

[0002] The traditional agricultural production model mainly relies on manual labor for sowing and fertilizing. Manual operation is not only labor-intensive, but also prone to uneven sowing depth and uneven fertilizer application due to differences in experience and improper operation, affecting crop growth and yield. In addition, fertilization under traditional methods is not accurate enough, and there is often a phenomenon of too much or too little fertilizer, resulting in fertilizer waste and even affecting soil and water resource pollution.

[0003] The patent with the patent announcement number CN205883939U relates to the technical field of sowing and fertilizing machinery, including wheat sowing and fertilizing machinery and a device for spraying wheat seeds and fertilizers. The patented wheat seed and fertilizer sprayer is a multifunctional agricultural machinery for wheat sowing and fertilization. The wheat seed and fertilizer sprayer can spray the seeds and fertilizers at the same time as sowing and fertilizing, reducing the mixing of seeds and fertilizers and realizing the integration of wheat farming operations. The patent is simple to operate, convenient and practical, highly feasible, and highly targeted. It uses low-toxic and low-volume pesticides to reduce damage to the soil environment, and can save manpower and time in the farming process of mixing seeds and fertilizers, saving manpower and time, achieving precise application of pesticides and facilitating wheat sowing, efficient, time-saving and labor-saving effects.

[0004] The above patent can eliminate the farming steps of mixing seeds and fertilizers, save manpower and time, achieve precise application of pesticides, and facilitate efficient, time-saving and labor-saving wheat sowing. However, when sowing, the seeds may be sown too densely, which may cause competition between plants to become very fierce, especially when sunlight, water and nutrients are limited. Overly dense planting will cause crops to block each other, affecting photosynthesis, thereby leading to poor growth. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an agricultural sowing and fertilizing machine that solves the problems raised in the above-mentioned background technology.

When the No. 1 cover plate releases the seal on the seed discharge port, the No. 2 cover plate will seal the discharge port, so that the gap between the seeds and the fertilizer is discharged, ensuring that the fertilizer and the seeds have enough separation distance in the soil, so as to avoid direct contact between the fertilizer and the seeds, thereby preventing the fertilizer from burning the seeds and affecting germination and growth.

[0008] According to the above technical solution, the side of the sliding rod close to the sliding sleeve is rotatably mounted on the end of the push plate away from the sliding sleeve, the seed outlet matches the shape of the No. 1 cover plate, and the seed outlet matches the shape of the No. 1 cover plate in order to seal the seed outlet, the material outlet matches the shape of the No. 2 cover plate, and the material outlet matches the shape of the No. 2 cover plate in order to seal the material outlet, and the length of the rotating rod is half of the connecting rod. The length of the rotating rod is half of the connecting rod in order to facilitate pulling the connecting rod to move when the rotating rod rotates.

[0009] According to the above technical solution, a bulldozer device for burying the soil pit after sowing and a dredging device for dredging the seed outlet are also provided at the bottom of the support platform. The bulldozer device includes a rack, a gear, a screw, a fixed plate, a push plate, a fixed rod, a cross bar, a fixed block and a knocking rod. The rack is fixedly installed on the side of the sliding rod away from the seed outlet, the fixed plate is fixedly installed on the bottom of the support platform, the gear is rotatably installed on the side of the fixed plate close to the rack, one end of the screw is rotatably installed on the side of the fixed plate close to the rack, and the other end of the screw is fixedly installed on the side of the gear close to the rack, the push plate is threadedly connected to the screw, and the fixed rod is fixedly installed The bottom of the fixed plate, the cross bar is fixedly installed on the side of the fixed bar close to the push plate, the fixed block is fixedly installed on the top of the cross bar, and the knocking rod is rotatably installed on the side of the push plate away from the fixed bar. The knocking rod rotates toward the direction of the support platform to push the No. 1 torsion spring to accumulate force. When the knocking rod is out of contact with the fixed block, the No. 1 torsion spring will drive the knocking rod to rotate downward quickly. The rapid downward rotation of the knocking rod will knock on the harder soil at the bottom to break the larger protrusions. If the hard lumps are not broken or loosened during the burying process, the soil may become more compacted, making the soil around the seeds more difficult to breathe and retain water, further affecting the germination and root development of the seeds.

[0010] According to the above technical solution, the rack is meshed with the gear, and a No. 1 torsion spring is provided between the knocking rod and the push plate. The No. 1 torsion spring is provided to drive the knocking rod back to its original position. The top of the fixed block is set as an arc surface. The fixed block is provided with an arc surface to facilitate pushing the knocking rod to rotate, and the cross bar passes through the push plate.

[0011] According to the above technical scheme, the dredging device includes a sliding plate, a support plate, a hydraulic device, a No. 1 hose, a water spray head, a No. 2 hose and a water storage tank. The sliding plate is slidably installed on the side of the push plate close to the knocking rod, the support plate is slidably installed on the top of the push plate, the hydraulic device is fixedly installed on the top of the support plate, the output end of the hydraulic device slides through the support plate, the water spray head is fixedly installed on the side of the push plate close to the support plate, and the water storage tank is fixedly installed on the top of the support platform. The hydraulic device is connected to the water spray head through a No. 1 hose, and the hydraulic device is connected to the water storage tank through a No. 2 hose. The movable end of the hydraulic device moves toward the inside of the hydraulic device to push the liquid inside the hydraulic device through the No. 1 hose and the water spray head to spray out. The water spray head sprays the liquid and sprays the liquid on the soil surface. Sprinkling water helps the fertilizer to dissolve and accelerates its penetration, ensuring that the fertilizer can better combine with the soil and facilitate crop absorption.

[0012] According to the above technical scheme, the dredging device also includes a vertical plate, a rotating rod, a protrusion rod, a rotating pressure rod and an insertion rod. The vertical plate slides through the support plate, the vertical plate is fixedly installed on the top of the sliding plate, the protrusion rod is slidably installed on the bottom of the support platform, one end of the rotating rod is rotatably installed on the top of the vertical plate, and the other end of the rotating rod is rotatably installed on the side of the protrusion rod close to the vertical plate. The rotating pressure rod is rotatably installed at the bottom of the seed outlet, and the insertion rod slides through the top of the rotating pressure rod. The protrusion will push the rotating pressure rod to rotate in the direction of the seed outlet. The rotating pressure rod rotating in the direction of the seed outlet will push the insertion rod to dredge the inside of the seed outlet to avoid seeds getting stuck in the seed outlet. Unclogging the seed outlet can ensure that seeds flow out of the seeder unimpeded, avoid uneven sowing or failure to release seeds normally due to blockage, which helps to achieve accurate sowing.

[0013] According to the above technical scheme, the sliding plate is a telescopic plate, and a No. 1 spring is provided between the sliding plate and the push plate. The No. 1 spring is provided to drive the push plate back to its original position. A pressure control valve is provided between the hydraulic device and the No. 1 hose. The pressure control valve is provided to push the liquid inside the hydraulic device to be discharged when the movable end of the hydraulic device moves toward the inside of the hydraulic device. A one-way valve is provided between the hydraulic device and the No. 2 hose. The one-way valve is provided to control the one-way flow of liquid inside the water tank into the hydraulic device. A No. 2 torsion spring is provided between the rotating pressure rod and the seed outlet. The No. 2 torsion spring is provided to drive the rotating pressure rod back to its original position. A No. 2 spring is provided between the insertion rod and the rotating pressure rod. The No. 2 spring is provided to drive the insertion rod back to its original position. The bump at the bottom of the bump rod is provided with an inclined surface.

[0014] The present invention provides an agricultural sowing and fertilizing machine, which has the following beneficial effects: (1) In the present invention, since the connecting rod is in reciprocating motion, when the connecting rod moves downward, it drives the push plate back to its original position. When the push plate returns to its original position, the sliding rod drives the No. 1 cover plate back to its original position to seal the seed outlet. The No. 1 cover plate will continue to reciprocate to open and close the seed outlet to avoid the situation where the competition between plants becomes very fierce if the seeds are scattered too densely during sowing. Especially when sunlight, water and nutrients are limited, overly dense planting will cause the crops to block each other, affecting photosynthesis, thereby causing poor growth and reducing yield.

[0015] (2) In the present invention, the reciprocating rotation of the gear drives the lead screw to rotate reciprocatingly. When the sliding rod slides in the direction away from the square plate, the rack drives the gear to rotate in the direction of the push plate, and the lead screw is driven by the gear to rotate in the direction of the push plate. The rotation of the lead screw drives the push plate to move in the direction close to the seed outlet. The movement of the push plate in the direction of the seed outlet will bury the soil that was originally turned over. Burying the seeds can effectively reduce the foraging opportunities of birds and insects, prevent them from pecking at or damaging the seeds, and thus improve the survival rate of the crops.

[0016] (3) In this invention, the rotation of the striking rod toward the support platform will push the No. 1 torsion spring to accumulate force. When the striking rod is out of contact with the fixed block, the No. 1 torsion spring will drive the striking rod to rotate downward rapidly. The rapid downward rotation of the striking rod will knock on the harder soil at the bottom to break the larger protrusions. If the hard lumps are not broken or loosened during the burying process, the soil may become more compacted, making it more difficult for the soil around the seeds to breathe and retain water, further affecting the germination of the seeds and the development of the root system.

[0017] (4) In this invention, the movable end of the hydraulic device moves toward the inside of the hydraulic device, which pushes the liquid inside the hydraulic device to be sprayed out through the No. 1 hose and the sprinkler head. The sprinkler head sprays the liquid onto the soil surface. Sprinkling water helps the fertilizer to dissolve and accelerates its penetration, ensuring that the fertilizer can better combine with the soil and facilitate crop absorption.

[0018] (5) In the present invention, the movement of the rotating rod will push the projection rod to move, and the movement of the projection rod will cause the rotating pressure rod to contact the projection of the projection rod, and the projection will push the rotating pressure rod to rotate toward the seed outlet. The rotation of the rotating pressure rod toward the seed outlet will push the insertion rod to clear the inside of the seed outlet to prevent the seeds from getting stuck in the seed outlet. Clearing the seed outlet can ensure that the seeds flow out of the seeder unimpeded, avoiding uneven sowing or failure to release seeds normally due to blockage, which helps to achieve accurate sowing.

Too dense planting will cause crops to block each other, affecting photosynthesis, thereby causing poor growth and reducing yield.

[0023] The discharging device also includes a seed outlet 9, a discharging outlet 10, a No. 1 cover plate 16, a No. 2 cover plate 17, a square plate 18, a telescopic rod 19, a No. 1 connecting rod 191, a No. 2 connecting rod 192 and a pushing rod 193. The seed outlet 9 is arranged at the bottom of the support platform 1, and the seed outlet 9 passes through the bottom of the seed storage frame 3. The discharging outlet 10 is arranged at the bottom of the support platform 1, and the discharging outlet 10 passes through the bottom of the fertilizer frame 2. The square plate 18 is fixedly mounted at the bottom of the support platform 1, and the telescopic rod 19 is slidably mounted on the side of the square plate 18 away from the seed outlet 9. The No. 1 cover plate 16 is rotatably mounted at the bottom of the seed outlet 9, and the side of the No. 1 cover plate 16 away from the seed outlet 9 is rotatably mounted at the bottom of the sliding rod 15, and the pushing rod 193 is slidably mounted at the bottom of the support platform 1. The No. 2 cover plate 17 is rotatably mounted at the bottom of the seed outlet 9. It is installed at the bottom of the discharge port 10, one end of the No. 2 cover plate 17 away from the discharge port 10 is rotatably installed at the bottom of the push rod 193, one end of the No. 1 connecting rod 191 is rotatably installed at the bottom of the sliding rod 15, the other end of the No. 1 connecting rod 191 is rotatably installed at the bottom of the telescopic rod 19, one end of the No. 2 connecting rod 192 is rotatably installed at the bottom of the telescopic rod 19, and the other end of the No. 2 connecting rod 192 is rotatably installed at the bottom of the push rod 193. When the No. 1 cover plate 16 releases the seal on the seed discharge port 9, the No. 2 cover plate 17 will seal the discharge port 10, so that the gap between the seeds and the fertilizer is discharged, ensuring that the fertilizer and the seeds have enough separation distance in the soil, so as to avoid direct contact between the fertilizer and the seeds, thereby preventing the fertilizer from burning the seeds and affecting germination and growth.

[0024] The side of the sliding rod 15 close to the sliding sleeve 13 is rotatably mounted on the end of the pushing plate 14 away from the sliding sleeve 13, the seed outlet 9 matches the shape of the No. 1 cover plate 16, and the seed outlet 9 matches the shape of the No. 1 cover plate 16 in order to seal the seed outlet 9, the material outlet 10 matches the shape of the No. 2 cover plate 17, and the material outlet 10 matches the shape of the No. 2 cover plate 17 in order to seal the material outlet 10, and the length of the rotating rod 11 is half of the connecting rod 12. The length of the rotating rod 11 is half of the connecting rod 12 in order to facilitate pulling the connecting rod 12 to move when the rotating rod 11 rotates.

[0025] When this embodiment is working: when sowing and fertilizing are needed, the machine is first installed on the traction device through the fixing frame 4, and the traction device is used to drive the machine to move to sow and fertilize the farmland. Before sowing and fertilizing, the fertilizer frame 2 and the seed storage frame 3 need to be filled first. When the traction device drives the machine to move for sowing, it will drive the large wheel 6 to rotate, and the rotation of the large wheel 6 will drive the rotating rod 11 to rotate. The rotation of the rotating rod 11 will continuously drive the connecting rod 12 to reciprocate up and down. When the connecting rod 12 moves upward, it will push the sliding sleeve 13 to slide upward, and the sliding sleeve 13 will push the connecting rod 12 to move upward. The push plate 14 moves, and the movement of the push plate 14 will push the sliding rod 15 to slide in the direction of the square plate 18. The movement of the sliding rod 15 will drive the No. 1 cover plate 16 to rotate. The rotation of the No. 1 cover plate 16 will release the seal of the seed outlet 9 to discharge the seeds from the seed outlet 9. Since the connecting rod 12 is a reciprocating motion, when the connecting rod 12 moves downward, it will drive the push plate 14 to return to its original position. When the push plate 14 returns to its original position, the sliding rod 15 will drive the No. 1 cover plate 16 to return to its original position to seal the seed outlet 9, and the No. 1 cover plate 16 will continue to reciprocate to seal the seed outlet 9. The gap is opened and closed to avoid that when sowing, if the seeds are scattered too densely, the competition between plants will become very fierce, especially when the sunlight, water and nutrients are limited. Too dense planting will cause the crops to block each other, affecting photosynthesis, resulting in poor growth and reduced yield. When the sliding rod 15 slides toward the square plate 18, it will push the No. 1 connecting rod 191 to move, and the movement of the No. 1 connecting rod 191 will push the telescopic rod 19 to move away from the square plate 18. The sliding of the telescopic rod 19 in the direction away from the square plate 18 will pull the No. 2 connecting rod 192 to move, and the No. 2 connecting rod 191 will push the No. 1 connecting rod 191 to move away from the square plate 18. The movement of cover plate 92 will pull the push rod 193 to slide in the direction of square plate 18. The movement of push rod 193 will drive cover plate 17 No. 2 to rotate. The rotation of cover plate 17 No. 2 will seal the discharge port 10. If the discharge port 10 is sealed, the fertilizer cannot be discharged. When cover plate 16 No. 1 releases the seal on seed discharge port 9, cover plate 17 No. 2 will seal the discharge port 10, so that the seeds and fertilizer are discharged through the gap, ensuring that there is enough separation distance between the fertilizer and the seeds in the soil, so as to avoid direct contact between the fertilizer and the seeds, thereby preventing the fertilizer from burning the seeds and affecting germination and growth.

[0026] See also Figure 1-Figure 9On the basis of the above embodiment, in another embodiment of the present invention, a bulldozer device for burying the soil pit after sowing and a dredging device for dredging the seed outlet 9 are further provided at the bottom of the support platform 1.

The rack 20 is fixedly mounted on the side of the sliding rod 15 away from the seed outlet 9, the fixed plate 23 is fixedly mounted on the bottom of the support platform 1, the gear 21 is rotatably mounted on the side of the fixed plate 23 close to the rack 20, one end of the screw 22 is rotatably mounted on the side of the fixed plate 23 close to the rack 20, and the other end of the screw 22 is fixedly mounted on the side of the gear 21 close to the rack 20, and the push plate 24 and the screw 22 are threaded. The fixing rod 25 is fixedly mounted on the bottom of the fixing plate 23, the cross bar 26 is fixedly mounted on the side of the fixing rod 25 close to the push plate 24, the fixing block 27 is fixedly mounted on the top of the cross bar 26, and the knocking rod 28 is rotatably mounted on the side of the push plate 24 away from the fixing rod 25. The rotation of the knocking rod 28 toward the direction of the support platform 1 will push the No. 1 torsion spring to accumulate force. When the knocking rod 28 is out of contact with the fixing block 27, the No. 1 torsion spring will drive the knocking rod 28 to rotate downward rapidly. The rapid downward rotation of the knocking rod 28 will knock on the harder soil at the bottom to break the larger protrusions. If the hard lumps are not broken or loosened during the burying process, the soil may become more compacted, making the soil around the seeds more difficult to breathe and retain water, further affecting the germination and root development of the seeds.

[0027] The rack 20 is meshed with the gear 21, and a torsion spring No. 1 is provided between the knocking rod 28 and the push plate 24.

The movable end of the hydraulic device 32 moves toward the inside of the hydraulic device 32 to push the liquid inside the hydraulic device 32 to be sprayed out through the No. 1 hose 33 and the water spray head 34. The liquid sprayed by the water spray head 34 will spray the liquid on the soil surface. Sprinkling water helps the fertilizer to dissolve and accelerate its penetration, ensuring that the fertilizer can be better combined with the soil and is convenient for crop absorption.

[0029] The dredging device also includes a vertical plate 37, a rotating rod 38, a protruding rod 39, a rotating pressure rod 391 and an inserting rod 392.

The rotating pressure rod 391 is rotatably mounted on the bottom of the seed outlet 9, and the inserting rod 392 slides through the top of the rotating pressure rod 391. The protruding block will push the rotating pressure rod 391 to rotate toward the seed outlet 9. The rotating pressure rod 391 rotates toward the seed outlet 9 and pushes the inserting rod 392 to dredge the inside of the seed outlet 9 to prevent seeds from getting stuck in the seed outlet 9. Unclogging the seed outlet 9 can ensure that seeds flow out of the seeder unimpeded, and avoid uneven sowing or failure to release seeds normally due to blockage, which helps to achieve accurate sowing.

[0030] The sliding plate 30 is a telescopic plate. A No. 1 spring is provided between the sliding plate 30 and the push plate 24. The No. 1 spring is provided to drive the sliding plate 30 back to its original position. A pressure control valve is provided between the hydraulic device 32 and the No. 1 hose 33.

A one-way valve is provided between the hydraulic device 32 and the No. 2 hose 35. The one-way valve is provided to control the one-way flow of liquid inside the water storage tank 36 into the hydraulic device 32. A No. 2 torsion spring is provided between the rotating pressure rod 391 and the seed outlet 9. The No. 2 torsion spring is provided to drive the rotating pressure rod 391 back to its original position. A No. 2 spring is provided between the insertion rod 392 and the rotating pressure rod 391. The No. 2 spring is provided to drive the insertion rod 392 back to its original position. The bump at the bottom of the bump rod 39 is provided with an inclined surface.

[0031] When the present embodiment is working, when the sliding rod 15 reciprocates, the rack 20 is driven to reciprocate, the reciprocating movement of the rack 20 drives the gear 21 to reciprocate, the reciprocating rotation of the gear 21 drives the screw rod 22 to reciprocate, and when the sliding rod 15 slides in the direction away from the square plate 18, the rack 20 drives the gear 21 to rotate in the direction of the push plate 14, and the screw rod 22 is driven by the gear 21 to rotate in the direction of the push plate 14, and the rotation of the screw rod 22 drives the push plate 24 to move in the direction close to the seed outlet 9, and the movement of the push plate 24 in the direction of the seed outlet 9 will bury the soil that was originally turned over, and burying the seeds can effectively reduce the foraging opportunities of birds and insects, prevent them from pecking or damaging the seeds, thereby improving the crop yield. The survival rate of the seed will be improved by the movement of the push plate 24 toward the seed outlet 9, which will drive the knocking rod 28 to move. The movement of the knocking rod 28 will contact the fixed block 27, and the fixed block 27 will push the knocking rod 28 to rotate in the direction close to the support platform 1. The rotation of the knocking rod 28 in the direction of the support platform 1 will push the No. 1 torsion spring to accumulate force. When the knocking rod 28 is out of contact with the fixed block 27, the No. 1 torsion spring will drive the knocking rod 28 to rotate downward quickly. The rapid downward rotation of the knocking rod 28 will knock on the harder soil at the bottom to break the larger protrusions. If the hard lumps are not broken or loosened during the burying process, the soil may become more compacted, making the soil around the seeds more difficult to breathe and retain water, further affecting the germination and root development of the seeds.

[0032] When the knocking rod 28 rotates upward, it will push the sliding plate 30 to slide upward. The sliding plate 30 sliding upward will push the movable end of the hydraulic device 32 to move toward the inner wall of the hydraulic device 32. The movable end of the hydraulic device 32 moves toward the inside of the hydraulic device 32, which will push the liquid inside the hydraulic device 32 to be sprayed out through the No. 1 hose 33 and the sprinkler head 34. The sprinkler head 34 sprays the liquid to spray the liquid on the soil surface. Sprinkling water helps the fertilizer to dissolve and accelerate its penetration, ensuring that the fertilizer can be better combined with the soil and is convenient for crops to absorb. The upward movement of the sliding plate 30 will push the turning The rod 38 moves, and the movement of the rotating rod 38 will push the protrusion rod 39 to move. The movement of the protrusion rod 39 will cause the rotating pressure rod 391 to contact the protrusion of the protrusion rod 39, and the protrusion will push the rotating pressure rod 391 to rotate toward the seed outlet 9. The rotation of the rotating pressure rod 391 toward the seed outlet 9 will push the insertion rod 392 to clear the inside of the seed outlet 9 to prevent the seeds from getting stuck in the seed outlet 9. Clearing the seed outlet 9 can ensure that the seeds flow out of the seeder unimpeded, avoid uneven sowing or failure to release the seeds normally due to blockage, which helps to achieve accurate sowing.
