When the small gear 209 rotates, it will drive the second rotating shaft 203 to rotate quickly. When the second rotating shaft 203 rotates, it will drive the second disc plow 205 to rotate.

[0028] A first rotating shaft 202 is rotatably connected to and penetrates the outer surfaces of the two mounting frames 201 near the front side, a plurality of first disc plows 204 are symmetrically fixedly connected to the outer surface of the first rotating shaft 202, a second pulley 207 is fixedly connected to the outer surface of the first rotating shaft 202 near the middle, a first pulley 206 is fixedly connected to the outer surface of the second rotating shaft 203 near the middle, a first transmission belt 208 is transmission-connected between the outer surfaces of the first pulley 206 and the second pulley 207, when the second rotating shaft 203 rotates, the first pulley 206 drives the second pulley 207 to rotate through the first transmission belt 208, when the second pulley 207 rotates, it drives the first rotating shaft 202 and the first disc plow 204 to rotate rapidly, thereby effectively destroying the surface of the field and playing the role of cultivating the land.

[0029] The bottom of the seed box 401 is symmetrically fixedly connected with a bracket 405, and the bracket 405 is fixedly connected to the top of the mounting plate 109. The outer surface of the feed channel 404 passes through the top of the mounting plate 109 and extends downward. The seed box 401 is located at the rear side of the mounting frame 201. The bottom of the feed channel 404 is lower than the bottom of the first disc plow 204. The bracket 405 is used to fix the seed box 401 on the mounting plate 109.

[0030] The steps of using the present invention are as follows: the device is connected to the trailer 113 through the hook on the agricultural vehicle, and then the wheel 115 at the bottom of the tail frame 114 is used to drag the device in the farmland. When it is necessary to carry out farming and fertilizing operations, the motor 406 and the electric push rod 112 are started. When the electric push rod 112 is started and extended, it will push the second connecting shaft 111 to move forward and downward as a whole, thereby driving the mounting plate 109 to move from the rear of the longitudinal beam 101 to the bottom and reduce the height. During the process, the first connecting rod 105 and the second connecting rod 106 rotate synchronously, and in parallel The characteristics of the quadrilateral ensure that the mounting plate 109 is parallel to the longitudinal beam 101, and after the motor 406 is started, the fourth pulley 410 is driven to rotate through the driving shaft 407, and when the fourth pulley 410 rotates, it drives the third pulley 211 to rotate synchronously through the second transmission belt 212, and when the third pulley 211 rotates, it drives the large gear 210 to rotate, and when the large gear 210 rotates, it drives the small gear 209 to rotate faster, and when the small gear 209 rotates, it drives the second rotating shaft 203 to rotate quickly, and at this time, the second rotating shaft 203 begins to drop forward as a whole, and the surface follows the rotation. The rotating second disc plow 205 will break up the field. During the process, when the second shaft 203 rotates, the first pulley 206 on the surface will drive the second pulley 207 to rotate synchronously through the first transmission belt 208. When the second pulley 207 rotates, it will drive the first shaft 202 and the first disc plow 204 to rotate quickly, thereby effectively destroying the surface of the field and playing the role of arable land. As the device moves forward, the field can be effectively plowed, and when the drive shaft 407 rotates, it will drive the round roller 408 inside the circular shell 403 to rotate. During the rotation of the round roller 408, the surface When the seed collecting groove 409 is facing upwards, the seeds inside the seed box 401 will slide down under the action of gravity and enter the seed collecting groove 409 through the connecting port 402; when the seed collecting groove 409 rotates to a downward state, the seeds inside will enter the feeding channel 404 and fall downward into the field; since the seed collecting groove 409 is in the shape of long strips, the seeds inside will be evenly arranged inside the seed collecting groove 409 during the rotation process; therefore, they will be in a neat long strip state after being discharged, which greatly increases the sowing area, thereby effectively improving the overall sowing efficiency and having good market competitiveness.

[0031] Embodiment 2: Figure 1-Figure 3 , Figure 7 and Figure 8As shown, the difference between the embodiment and the basis is that a plurality of telescopic rods 304 are fixedly connected to the top of the lifting plate 301, and the telescopic rods 304 are fixedly connected to the bottom of the mounting plate 109, and the lifting plate 301 is located in front of the feeding channel 404, and the outer sleeve of the telescopic rods 304 is provided with springs 305, and the lifting plate 301 is symmetrically fixedly connected with two groups of inclined bulldozer pieces 303 near the front surface, and the bottom of the lifting plate 301 is fixedly connected with a bulldozer plate 302 near the rear side, and the backfilling plate 306 is located at the rear side of the feeding channel 404, and the bottom of the backfilling plate 306 is higher than the bottom of the bulldozer plate 302. When the tillage component 2 plows the field, the spring 305 will push the lifting plate 301 downward to move downward, and the bulldozer pieces 303 and bulldozer plates 302 at the bottom of the lifting plate 301 will be inserted into the ground and move forward with the device. During the process, the tilted The V-shaped bulldozer blade 303 will push the loose soil in the passing area outward, thereby making the land softer, and then the V-shaped bulldozer plate 302 moves forward again. During the process, the loose soil will fit the inclined surface of the bulldozer plate 302 and spread out to both sides, thereby forming a groove with a certain depth and a width greater than the width of the feeding channel 404. At this time, the loose soil will accumulate on both sides of the groove and form a certain height. Then, after the seeds fall into the groove, it can effectively prevent the seeds from floating on the ground and unable to grow. When the seeds fall into the groove, when the backfilling plate 306 at the back is pushed forward, the accumulated loose soil will converge to the center along the inclined surface of the backfilling plate 306, thereby refilling the groove and burying the seeds. The telescopic rod 304 plays a role in limiting the lifting plate 301, so that it can be stably lifted and lowered and the maximum descent height is limited to prevent the bottom of the backfilling plate 306 from being lower than the ground height.

[0032] The use steps of the present invention are as follows: during the movement of the device, when the tillage component 2 plows the field, the spring 305 pushes the lifting plate 301 downward to move downward. Since the land becomes soft after plowing, the bulldozer 303 and the bulldozer board 302 at the bottom of the lifting plate 301 will be inserted into the ground and move forward with the device. During the movement, each small inclined bulldozer 303 will push the loose soil in the passing area outward, thereby making the land softer. Then the V-shaped bulldozer board 302 pushes the loose soil forward again. During the pushing process, the loose soil will fit the bulldozer board The inclined surface of 302 is arranged on both sides, thereby forming a groove with a certain depth and a width greater than the width of the feeding channel 404. At this time, the loose soil will accumulate on both sides of the groove and form a certain height. After the seeds fall into the groove, it can effectively prevent the seeds from floating on the ground and unable to grow. When the seeds fall into the groove, when the backfilling plate 306 at the back is pushed forward, the accumulated loose soil will converge toward the center along the inclined surface of the backfilling plate 306, and then re-fill the groove and bury the seeds. The overall structure is simple, and there is no need for manual digging and burying of seeds, which effectively improves farming efficiency.

[0034] The outer surfaces of both sides of the fifth rotating seat 504 are rotatably connected with a rotating frame 505 extending downward, and the rotating frame 505 is tilted backward. Both ends of the inner cylinder 507 are fixedly connected with connecting ends 508, one of which is fixedly connected to the bottom end of the liquid outlet pipe 503 through a connecting head, and the two connecting ends 508 are fixedly connected to the two rotating frames 505 respectively. An inner cavity 509 is opened near the bottom of the inner cylinder 507, and the inner cavity 509 is fixedly connected to one of the connecting ends 508. A limit block 506 is fixedly connected to the outer surface of the frame 505 near the front side, and the top of the limit block 506 conflicts with the bottom of the mounting plate 109. One of the connection ends 508 is hollow. After being connected to the liquid outlet pipe 503 through the connector, the liquid fertilizer in the fertilizer box 501 will enter the inner cavity 509 inside the inner cylinder 507. The limit block 506 is used to limit the rotating frame 505, so that the rotating frame 505 can only rotate backward in the initial tilted state, and cannot rotate forward, to avoid excessive rotation.

[0035] The outer surface of the inner cylinder 507 is rotatably connected to the outer cylinder 510. The outer surface of the outer cylinder 510 is provided with a plurality of strip grooves 511 at equal intervals. A strip opening 513 is provided near the bottom of the outer surface of the inner cylinder 507. The strip opening 513 and the strip grooves 511 are of the same size. The outer surface of the outer cylinder 510 is fixedly connected with a plurality of groups of convex heads 512 at equal intervals. The positions of the convex heads 512 and the strip grooves 511 are staggered. The outer cylinder 510 is rotatably sleeved on the inner cylinder 507. 7, and the inner wall of the outer cylinder 510 is in contact with the outer wall of the inner cylinder 507, and the two ends of the outer cylinder 510 are rotatably connected through bearings and connecting ends 508 at both ends of the inner cylinder 507. During the movement of the device, the inner cylinder 507 and the outer cylinder 510 are under the action of weight, and as the device moves forward, the outer cylinder 510 will roll in the field under the action of friction, while the inner cylinder 507 will not rotate, and the strip grooves 511 on the surface of the outer cylinder 510 will not rotate. When the strip groove 511 and the strip opening 513 are staggered, the inner cavity 509 is in a closed state. By arranging the convex head 512 on the surface of the outer cylinder 510, the friction between the outer cylinder 510 and the ground is increased, so that it can roll smoothly in the field. In addition, the convex head 512 has the function of supporting the outer cylinder 510, so that its surface does not directly contact the field, and the loose soil is prevented from blocking the strip groove 511. In addition, the length of the outer cylinder 510 is greater than the width of the bulldozer 302. Therefore, when the outer cylinder 510 rolls in the field, the position near the two ends will fall on the land that has been plowed and has a certain hardness. With the support of the convex head 512, it is further ensured that the outer cylinder 510 has a certain distance from the ground, so that the strip groove 511 will not be blocked by the soil.

[0036] The use steps of the present invention are as follows: during the movement of the device, the inner cylinder 507 and the outer cylinder 510 will fall to the ground under the action of weight, and the liquid fertilizer in the fertilizer box 501 will enter the inner cavity 509 inside the inner cylinder 507 through the liquid outlet pipe 503. As the device moves forward, under the action of friction, the outer cylinder 510 will roll in the field, while the inner cylinder 507 will not rotate. As the outer cylinder 510 rotates, the strip grooves 511 on the surface will continuously overlap with the strip openings 513 on the surface of the inner cylinder 507. Whenever the two overlap, the liquid fertilizer in the inner cavity 509 will be discharged outward and will be in the same long strip shape as the sowing area. When the strip grooves 511 and the strip openings 513 are staggered, the inner cavity 50 9 will be in a closed state, therefore, as the device moves forward, the land after sowing can be fertilized, and the fertilization area is wide and the uniformity is high, which provides a farming effect and farming efficiency. When the outer cylinder 510 passes over the raised hard block in the field, the rotating frame 505 will rotate backward, so that the outer cylinder 510 will rise in height and pass over the raised part, and then the rotating frame 505 will rotate forward again under the weight of the outer cylinder 510 and the inner cylinder 507. When it rotates to the initial position, the limit block 506 will conflict with the mounting plate 109 to avoid excessive rotation. This design prevents the outer cylinder 510 from being scratched when fertilizing in an uneven field, thereby improving the service life of the device and the stability of the fertilization function.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
