The present invention controls the rotating shell to always remain vertical to the ground, and the feeding shell in a rotating state will continue to rotate backwards, driving the rotating shell to descend in the process, and inserting the rotating shell into the ground under the action of the pointed cone. When the rotating shell and the feeding shell are both vertical to the ground, the rotating shell will be inserted into the deepest part of the ground. At this time, a pair of pointed cones will open to both sides to allow seeds to fall into the ground. As the rotating shell is pulled out of the ground, during the sowing process, when the rotating shell is released for sowing, it is first inserted into the ground and then pulled out of the ground, and the seeds are accurately placed in the holes inserted by the pointed cones, thereby achieving the effect of accurate sowing.

When the rotating roller drives the feed shell to rotate to forty-five degrees with the ground plane, as the rotating roller drives the feed shell to rotate ninety degrees, the feed shell rotates to the rear at forty-five degrees with the ground plane. During this period, sowing begins and ends. At this time, the rotating roller drives the rotating shell to rotate while revolving, and the equipment continues to move forward. The forward movement speed is coordinated with the rotation speed of the rotating roller, so that the rotating shell always maintains a vertical state with the ground, achieving the effect of vertically inserting the rotating shell into the ground and vertically pulling it out from the ground. In the pulling out process, the pointed cone is gradually closed until the pointed cone is completely pulled out of the soil. The pointed cone will be completely closed and will not clamp the sown seeds. At the same time, damage to the land around the sowing hole is avoided, which is convenient for subsequent burying of the seeds with soil. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The precision seeding device for agricultural planting involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0036] like Figure 1-11As shown, in one embodiment, a precision seeding device for agricultural planting is proposed, including a machine base 1, a rotating frame 101 is installed at the lower end of the machine base 1, a rotating roller 103 is rotatably connected in the rotating frame 101 through a driving rod 102, the driving rod 102 is connected to the output end of a driving motor 104 installed on the surface of the rotating frame 101, a seeding assembly 2 is arranged in the rotating roller 103, the seeding assembly 2 includes a soil entry mechanism 21 and a material discharge mechanism 22, the soil entry mechanism 21 includes a feed shell 211, a rotating shell 212 and a pointed cone 215, a plurality of feed shells 211 are installed in the rotating roller 103, the rotating shells 212 are all rotatably connected to the surface of the feed shell 211, the surfaces of the feed shell 211 and the rotating shell 212 are both provided with through holes 213, and a pair of pointed cones 215 are both rotatably connected in the rotating shell 212 through a rotating shaft 214;

[0037] The discharge mechanism 22 includes a cam 221, a push rod 223, a sleeve 222, a paddle 224 and a torsion spring 227. The cam 221 is installed in the feed shell 211, the sleeve 222 is installed in the rotating shell 212, the push rod 223 is slidably connected in the sleeve 222, the paddle 224 is installed on the surface of one of the pointed cones 215, and each group of pointed cones 215 is installed with mutually meshing tooth blocks 225 on the surface, and a shielding shell 226 is installed on the surface of one of the pointed cones 215. The torsion spring 227 is installed between the shielding shell 226 and the rotating shaft 214.

[0038] In actual application of the embodiment of the present invention, when the equipment moves forward on the ground, by controlling the rotation of the rotating roller 103, the rotating roller 103 will drive the feed shell 211 to rotate, and at the same time control the rotation of the rotating shell 212, so that the rotating shell 212 and the feed shell 211 maintain an angle of 45 degrees. When the rotation angle of the front feed shell 211 is 45 degrees with the ground, the rotating shell 212 will be perpendicular to the ground. Then, when the feed shell 211 rotates, the rotating shell 212 is controlled to remain perpendicular to the ground, and the feed shell 211 in the rotating state will continue to rotate backwards. The rotating shell 212 is driven to descend, and the rotating shell 212 is inserted into the ground under the action of the pointed cone 215. When the rotating shell 212 and the feeding shell 211 are both perpendicular to the ground, the rotating shell 212 will be inserted into the deepest part of the ground, and in the process of the feeding shell 211 being perpendicular to the ground from 45 degrees, the through holes 213 opened on the surfaces of the feeding shell 211 and the rotating shell 212 will overlap, so that the seeds in the feeding shell 211 enter the rotating shell 212, and at the same time, the cam 221 will push the push rod 223 to descend, and the push rod 223 pushes the dial block to rotate, and the dial block drives the pointed cone 21 5 rotates, and then with the cooperation of the tooth block 225, the pair of pointed cones 215 will open to both sides, so that the seeds fall into the ground. As the rotating roller 103 continues to rotate, the feed shell 211 moves backward from the vertical state to the ground and there will be an angle with the ground, while the rotating shell 212 is always controlled to be vertical to the ground. As the feed shell 211 rotates, it will drive the rotating shell 212 to rise, so that the rotating shell 212 is pulled out of the ground. In the process of pulling out the rotating shell 212, the cam 221 rotates relative to the push rod 223, and the pointed cones are opened by the torsion spring 227 and the tooth block 225. 215 and the paddle plate 224 rotate and reset, driving the push rod 223 to rise and reset until the feed shell 211 rotates to forty-five degrees with the ground. At this time, the pointed cone 215 will be closed, and the seeds will remain in the ground. During the sowing process, when the rotating shell 212 is released for sowing, it is first inserted into the ground and then pulled out of the ground, and the seeds are accurately placed in the hole where the pointed cone 215 is inserted, completing the effect of precise sowing. After the pointed cone 215 is closed, the rotating shell 212 is controlled to rotate and reset, so that it and the feed shell 211 maintain the original forty-five degree angle position again, preparing for inserting into the ground for the next sowing.

[0039] In one case of an embodiment of the present invention, when the rotating roller 103 rotates, it will drive the feed shell 211 to rotate. When the rotating roller 103 drives the feed shell 211 to rotate to forty-five degrees with the ground plane, as the rotating roller 103 drives the feed shell 211 to rotate ninety degrees, the feed shell 211 rotates to the rear at forty-five degrees with the ground plane. During this period, sowing begins and ends. At this time, the rotating roller 103 drives the rotating shell 212 to rotate while revolving, and the equipment continues to move forward. The forward movement speed is coordinated with the rotation speed of the rotating roller 103, so that the rotating shell 212 always remains vertical to the ground, achieving the effect of vertically inserting the rotating shell 212 into the ground and vertically pulling it out from the ground. In the pulling out process, the pointed cone 215 is gradually closed until the pointed cone 215 is completely pulled out of the soil. The pointed cone 215 will be completely closed and will not clamp the sown seeds. At the same time, it avoids damage to the land around the sowing hole, which is convenient for subsequent burying of the seeds with soil.

[0040] like Figure 8 and 13 As shown, as a preferred embodiment of the present invention, a connecting shaft 3 is rotatably connected inside the rotating roller 103 , a connecting rod 301 is installed on the surface of the feed shell 211 , and the connecting rod 301 and the connecting shaft 3 are connected through a first sprocket set 302 .

[0041] In actual application, by controlling the rotation of the connecting shaft 3, the connecting shaft 3 drives the connecting rod 301 to rotate through the first sprocket set 302, thereby achieving the effect of controlling the simultaneous rotation of the rotating shells 212 in the same group.

[0042] like Fig.13 and 16 As shown, as another preferred embodiment of the present invention, a servo motor 303 is installed on the surface of the rotating frame 101, a rotating rod 304 is installed on the output end of the servo motor 303, a first gear 305 is installed on the circumferential surface of the rotating rod 304, a second gear 306 is installed on the circumference of the driving rod 102, and a third gear 307 is installed on the circumferential surface of the connecting shaft 3, and the second gear 306 is meshed with the first gear 305 and the third gear 307.

[0043] When the embodiment of the present invention is actually applied, by controlling the rotation of the servo motor 303, the servo motor 303 will drive the rotating rod 304 to rotate, the rotating rod 304 drives the first gear 305 to rotate, the first gear 305 drives the second gear 306 to rotate, and the second gear 306 drives the two third gears 307 to rotate, thereby achieving the effect of controlling the rotation of the rotating shell 212. When the equipment is in the sowing stage and the rotating shell 212 needs to be reset after the sowing stage, the servo motor 303 will change the speed to control the rotating shell 212 to rotate relative to the feeding shell 211, so as to achieve the effect of keeping the rotating shell 212 vertical to the ground and rotating and resetting. In addition, the servo motor 303 controls the rotation of the rotating rod 304 and rotates at the same speed as the rotating roller 103, so that the second gear 306 is in a stationary state on the circumferential surface of the driving rod 102. At this time, the rotating shell 212 remains stationary with the feeding shell 211 to prevent the rotating shell 212 from rotating relative to the feeding shell 211.

[0045] In actual application of the embodiment of the present invention, when the rotating roller 103 rotates, when one group of feed troughs 401 moves to the top, the linkage rod 403 will drive the blocking block 404 to move, and open the feed trough 401. At this time, the seeds can enter the feed trough 401. As the rotating roller 103 rotates, the linkage rod 403 will drive the blocking block 404 to move, and block the feed trough 401, and at the same time push the seeds in the feed trough 401 into the feed shell 211 through the feed port 402, so as to achieve the effect of replenishing the seeds in the feed shell 211.

[0047] When the embodiment of the present invention is actually applied, through the action of the convex ring 408, when the feed trough 401 is about to move to the top, the raised part of the convex ring 408 will push the ball block 406 to move, and the ball block 406 drives the linkage rod 403 and the blocking block 404 to move, so that the feed trough 401 is opened, and then the seeds can be replenished in the feed trough 401, and then, under the action of the continuous rotation of the rotating roller 103, the ball block 406 is separated from the raised part of the convex ring 408, and at this time, under the action of the spring 407, the spring 407 will drive the linkage rod 403 to move and reset, so that the blocking block 404 blocks the feed trough 401 and pushes the seeds into the feed shell 211, thereby achieving the effect of replenishing seeds.

[0048] like Fig.13 and 17 As shown, as another preferred embodiment of the present invention, a fixing frame 5 is installed on the upper end of the machine base 1, a material storage barrel 501 is installed on the upper end of the fixing frame 5, a plurality of replenishing shells 502 are installed on the lower end of the material storage barrel 501, the replenishing shells 502 are all slidably connected to the rotating roller 103, a feeding roller 503 is rotatably connected inside the material storage barrel 501, a plurality of storage grooves 504 are opened on the circumferential surface of the feeding roller 503, a rotating shaft 505 is installed inside the feeding roller 503, and the rotating shaft 505 is connected to the output end of a rotating motor 506 installed on the surface of the material storage barrel 501.

[0049] When the embodiment of the present invention is actually applied, by controlling the operation of the rotating motor 506, the rotating motor 506 will drive the unloading roller 503 to rotate. Through the rotation of the unloading roller 503, the storage groove 504 opened on the surface of the unloading roller 503 will take away the seeds stored in the storage barrel 501, and then transport them to the replenishing shell 502. When the storage groove 504 on the rotating roller 103 moves to the top and opens, the seeds in the replenishing shell 502 will enter the storage groove 504, thereby achieving the effect of replenishing seeds.
