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 end of the discharge chute 6078 close to the discharge vertical groove 6077 is tilted downward. 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 compressed 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 groove 6077 to the inside of the discharge chamber 6052 and are discharged, so that the seeds are continuously sown during the movement of the sowing turntable 603 along the sowing path, which is convenient for sowing.

The width and length of the discharge vertical groove 6077 are smaller than the width and length of the connecting tube 6053, so that the seeds entering the discharge chute 6078 and the discharge vertical groove 6077 can completely enter 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.

[0023] The rotating material-dispensing unit 608 includes a rotating groove 6084 opened inside the other side shaft 6063, the rotating groove 6084 penetrates into the interior of the material 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 material storage chamber 6064, and the material storage chamber 6064 is evenly installed, one end of the rotating rod 6085 is rotatably connected to the side plate 602, 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, 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 inside the rotating sleeve 6082. 88.

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 seed-moving rod 6089 moves the seeds inside the storage chamber 6064 to avoid the seeds being blocked at the bottom of the storage chamber 6064, which facilitates the seed discharging and prevents the seeds from piling up 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 the discharging.

[0024] Working principle: When working, first, after the land is plowed, the equipment is moved to the path where the seeds need to be sown. When moving, the bottom of the roller 2 and the bottom of the support ring 604 are in contact with the ground. When moving, 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; 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 the top cover 6067 is unscrewed, the feed pipe 6066 is opened, and the seeds to be sown are put into the feed trough 6065 from 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. When the mobile vehicle 1 moves and drives the sowing turntable 603 to move along the seed sowing path, the sowing turntable 603 rotates counterclockwise continuously during the movement. When the connecting pipe 6053 inside the sowing turntable 603 rotates to below the bottom pipe 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 in the storage chamber 6064 roll into the discharge chamber 6052 from the discharge chute 6078 and the discharge vertical groove 6077. When the connecting pipe 6053 leaves from below the bottom pipe 6071, the stopper 6072 is resilient. The spring 6076 moves back downward under the elastic force of the spring 6076, so that the end of the discharge chute 6078 is closed by the inner wall of the bottom tube 6071 again, and the seed discharge channel is closed. 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 the seeds are discharged. 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 a high position, the seeds in the storage groove 6055 fall along the inclined discharge chute 6056 to the sowing path. At the same time, the inner side of the discharge chute 6056 is equidistantly provided with dispersion partitions 6057, so as to facilitate the uniform sowing of the seeds. During the counterclockwise rotation of the sowing turntable 603, the rotating sleeve 6082 is driven to rotate synchronously through the connecting rod 6083, and the inner tooth ring 6088 on the inner wall of the rotating sleeve 6082 is meshed with the second gear 6087, thereby driving the second gear 6087 to rotate counterclockwise, and 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-moving rod 6089 on the outer wall of the rotating rod 6085 moves the seeds inside the storage chamber 6064, on the one hand, avoiding the accumulation and blockage of seeds at the bottom of the storage chamber 6064, ensuring smooth discharge, and at the same time avoiding 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 discharge and the uniformity of seed sowing; 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.
