[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1) During operation, a discharge cavity is formed at an equal angle inside the sowing turntable, which is connected to the inner cavity on the inner wall of the inner cavity. When the sowing turntable rotates counterclockwise, pressure is generated on the compressed arc surface through the top plate, pushing the block to move upward, causing the seeds in the storage cavity to slide from the discharge chute and the discharge vertical chute into the discharge cavity and be discharged.

[0022] 3) During operation, a storage groove is provided on the side of the discharge chamber away from the inner chamber, so that after the seeds enter the discharge chamber, they are first concentrated inside the storage groove. As the sowing turntable rotates counterclockwise, the discharge groove at one end of the storage groove tilts, causing the seeds to be discharged from the tilted discharge groove, thereby increasing the seed sowing height and the impact force of the seeds reaching the ground. This facilitates the seeds to enter deeper into the soil at the sowing position and facilitates seed growth. Dispersion partitions are evenly spaced inside the discharge groove to further improve seed sowing uniformity.

[0023] 4) During operation, support rings are symmetrically installed on the outside of the sowing disc. When the sowing disc rotates, the bottom of the support ring contacts the ground, which can increase the seed discharge height. After the seeds are sown, the sowing disc will not crush the seeds discharged on the ground, thus protecting the seeds.

[0024] 5) During operation, the rotating sleeve is driven to rotate synchronously by the rotation of the sowing turntable, and then the rotating rod is driven to rotate in the opposite direction of the sowing turntable through the internal gear ring, the second gear and the first gear, so that the seeding rod moves the seeds inside the storage chamber to avoid the seeds being blocked at the bottom of the storage chamber, facilitating the seed discharging, and preventing the seeds from accumulating at the bottom of the storage chamber close to the side of the moving direction of the sowing turntable when the sowing turntable moves, thereby improving the uniformity of the discharging.

The top of the discharge vertical groove 6077 is symmetrically provided with a discharge chute 6078 on both sides. One end of the groove 6078 penetrates the side wall of the stopper 6072, and one end of the discharge chute 6078 is blocked by the side wall of the bottom tube 6071. The discharge chute 6078 is tilted downward near one end of the discharge vertical groove 6077. The discharge cavity 6052 is opened at an equal angle inside the sowing turntable 603. The discharge cavity 6052 is connected to the inner cavity 6051 on the inner wall of the inner cavity 6051. When the sowing turntable 603 rotates counterclockwise, pressure is generated on the pressure arc surface 6073 through the top plate 6054, pushing the stopper 6072. 072 moves upward, so that the seeds in the storage chamber 6064 slide from the discharge chute 6078 and the discharge vertical chute 6077 to the inside of the discharge chamber 6052 and are discharged, so that when the sowing turntable 603 moves along the sowing path, the seeds are continuously sown, which is convenient for sowing.

The width and length of the discharge vertical groove 6077 are both smaller than the width and length of the connecting pipe 6053, so that the seeds entering the discharge chute 6078 and the discharge vertical groove 6077 can completely enter the interior of the circular box 6062, so that the seeds discharged in a single time can be completely discharged for sowing, thereby improving the seed sowing effect.

[0041] The rotating material-dispensing unit 608 includes a rotating groove 6084 opened inside the other side shaft 6063, and the rotating groove 6084 extends into the interior of the storage chamber 6064. A rotating rod 6085 is rotatably installed inside the rotating groove 6084. The rotating rod 6085 is located on the outer wall of the inner part of the storage chamber 6064 and the storage chamber 6064 is evenly installed. One end of the rotating rod 6085 is rotatably connected to the side plate 602, and a first gear 6086 is coaxially installed on the rotating rod 6085. An empty groove 6081 is provided between the side shaft 6063 and the side plate 602. The rotating rod 6085 is located inside the empty groove 6081, and a rotating sleeve 6082 is provided inside the empty groove 6081. A connecting rod 6083 is installed at an equal angle between the rotating sleeve 6082 and the sowing turntable 603, and an inner gear ring 6086 is provided on the inner side of the rotating sleeve 6082. 88. A second gear 6087 is provided between the inner gear ring 6088 and the first gear 6086. The second gear 6087 is rotatably connected to the side plate 602. The second gear 6087 is meshed with the first gear 6086 and the inner gear ring 6088. The rotation of the sowing turntable 603 drives the rotating sleeve 6082 to rotate synchronously, and then drives the rotating rod 6085 to rotate in the opposite direction of the sowing turntable 603 through the inner gear ring 6088, the second gear 6087 and the first gear 6086, so that the material moving rod 6089 moves the seeds inside the storage chamber 6064 to avoid the seeds from being blocked at the bottom of the storage chamber 6064, facilitating the discharging of seeds, and at the same time avoiding the seeds from piling up at the bottom of the storage chamber 6064 near the moving direction of the sowing turntable 603 when the sowing turntable 603 moves, thereby improving the uniformity of discharging.

[0042] Working principle: When working, first, after the land is plowed, the equipment is moved to the path where the seeds need to be sown. During the movement, the bottom of the driving roller 2 and the bottom of the support ring 604 are in contact with the ground. During the movement, the rotation speed of the driving roller 2 is adjusted through the control panel 4, thereby adjusting the forward speed of the mobile vehicle 1. During the movement of the mobile vehicle 1, the sowing turntable 603 rotates continuously under the action of friction;

[0043] During the movement, since the side shaft 6063 on one side of the circular box 6062 is fixedly connected to one of the side plates 602, the circular box 6062 is fixed, and the sowing turntable 603 can rotate outside the circular box 6062. After unscrewing the top cover 6067, the feed pipe 6066 is opened, and the seeds to be sown are put into the feed trough 6065 through the feed pipe 6066. The inner bottom wall of the feed trough 6065 is provided with a feed slope, so that the seeds enter the storage cavity 6064. Then, the top cover 6067 is tightened to close the feed pipe 6066.

[0044] When the mobile vehicle 1 moves and drives the sowing turntable 603 to move along the seed sowing path, the sowing turntable 603 rotates continuously counterclockwise during movement. When the connecting pipe 6053 inside the sowing turntable 603 rotates to the bottom of the bottom tube 6071, the top plate 6054 at the end of the connecting pipe 6053 generates pressure on the compressed arc surface 6073 at the bottom of the stopper 6072, thereby pushing the stopper 6072 to move upward, so that the end of the discharge chute 6078 enters the storage chamber 6064 upward, so that part of the seeds inside the storage chamber 6064 rolls into the discharge chamber 6052 from the discharge chute 6078 and the discharge vertical groove 6077. When the connecting pipe 6053 leaves from the bottom of the bottom tube 6071, the stopper 6072 is elastic The spring 6076 moves back downward under the elastic force of the spring, so that the end of the discharge chute 6078 is again closed by the inner wall of the bottom tube 6071, closing the seed discharge channel. When the seeds are discharged, since the width and length of the discharge vertical groove 6077 are smaller than the width and length of the connecting pipe 6053, the seeds can completely enter the discharge cavity 6052 when discharging. After entering the discharge cavity 6052, the seeds fall into the inner side of the storage groove 6055. As the sowing turntable 603 rotates counterclockwise to the highest point, the seeds in the storage groove 6055 fall along the inclined discharge chute 6056 onto the sowing path. At the same time, dispersion partitions 6057 are equidistantly provided on the inner side of the discharge chute 6056, so as to facilitate uniform sowing of the seeds.

[0045] The second gear 6087 is meshed with the first gear 6086 on the rotating rod 6085, thereby driving the rotating rod 6085 to rotate clockwise. The rotation direction of the rotating rod 6085 is opposite to the moving direction of the sowing turntable 603, so that the material-dispensing rod 6089 on the outer wall of the rotating rod 6085 dispenses the seeds inside the storage chamber 6064, thereby avoiding the accumulation and blockage of the seeds at the bottom of the storage chamber 6064 and ensuring smooth discharging. At the same time, it avoids the accumulation of seeds at the bottom of the storage chamber 6064 close to the moving direction of the sowing turntable 603 when the sowing turntable 603 moves, thereby improving the uniformity of discharging and the uniformity of seed sowing.

[0046] When it is necessary to adjust the single seed sowing amount, it is only necessary to adjust the moving speed of the mobile vehicle 1 by adjusting the rotation speed of the driving roller 2, thereby adjusting the pressure holding time of the connecting pipe 6053 on the compressed arc surface 6073, thereby facilitating the adjustment of the single seed discharge amount.
