[0020] Reference Figure 1-4 As shown, an embodiment of the utility model is provided: a crop seed planting machine, including a base 1, which plays a supporting role, two wheels 2 are respectively arranged on the left and right sides of the base 1, a bracket 3 is arranged above the left and right ends of the base 1, and an armrest 4 is arranged above the rear end of the base 1, and the armrest 4 provides a support and force application position for the user, a material bin 5 is arranged between the base 1 and the armrest 4, and the material bin 5 is used to store seeds, and a conveying pipe 6 is arranged at the front end of the material bin 5, and the conveying pipe 6 is a hollow structure and is arranged obliquely downward, and the seeds slide downward under the action of gravity and enter the conveying pipe 6 from the material bin 5, and the conveying pipe 6 is sealed and connected to the material bin 5 and is communicated with the material bin 5, a transfer barrel 7 is arranged in the middle of the conveying barrel 6, and two discharge ports 71 are arranged in the transfer barrel 7, and the two discharge ports 71 correspond to the connection positions of the conveying pipe 6 and the transfer barrel 7, and the two discharge ports 71 are communicated with the conveying pipe 6, so that the seeds can The seed enters the transfer barrel 7 from the conveying pipe 6 and then falls into the conveying pipe 6 from the transfer barrel 7. The transfer barrel 7 is rotated and connected to the rotating member 72. The rotating member 72 is a cylindrical structure. The outer diameter of the rotating member 72 is adapted to the inner diameter of the transfer barrel 7. A groove 74 is provided inside the rotating member 72. The groove 74 is the same size as the discharge port 71 and can only accommodate one seed to prevent multiple seeds from being planted in one position, resulting in poor seed growth. When the rotating member 72 rotates, the seed falls into the groove 74 from the upper discharge port 71 and can only store one seed. When the groove 74 rotates to the lower discharge port 71, the seed falls out of the groove 74 and falls into the already dug pit from the conveying pipe 6. The rotating member 72 is connected to the first motor 73, and the first motor 73 is fixed on the material bin 5. An excavating device 8 is arranged at the front end of the conveying pipe 6 and below the bracket 3. A soil cover 9 is arranged below the rear end of the base 1. The soil cover 9 pushes the soil forward to bury the seeds.

[0021] Furthermore, the excavating device 8 includes a second motor 81, which is fixed on the inner wall of the bracket 3. The end of the second motor 81 is rotatably connected to the rotating rod 82. One end of the rotating rod 82 is connected to the rotating shaft of the second motor 81, and the other end is vertically provided with a connecting rod 83. A slider 84 is provided at the end of the connecting rod 83. A furrow opener 85 is provided on the side of the connecting rod 83. The furrow opener 85 is an arc-shaped structure and corresponds to the position of the covering device 9. A slide groove 86 is provided on the side of the furrow opener 85. The slide groove 84 is adapted to the shape of the slide groove 86. A chamfer is provided at the bottom of the front end of the device 85 to facilitate the furrow opener 85 to dig a hole. The radius of the furrow opener 85 is the same as the radius of the connecting rod 83. The connecting rod 83 rotates one circle just enough to make the furrow opener 85 dig once, so that the seed planting positions are evenly distributed on the land. The second motor 81 rotates to make the rotating rod 82 and the connecting rod 83 rotate together, and the slider 84 slides in the slide groove 86. When the slider 84 slides from one end of the slide groove 86 to the other end, the furrow opener 85 is pressed downward, and after another rotation, the furrow opener 85 is driven back to the initial position.

[0022] Furthermore, there is a gap between the front end of the delivery pipe 6 and the rear end of the furrow opener 85 to prevent the connecting rod 83 from colliding with the delivery pipe 6 when rotating.

[0023] Furthermore, a slope is provided around the inner side of the material bin 5 toward the discharge port 71 , and the seeds slide along the slope toward the discharge port 71 , so that there are seeds in the groove 74 at all times for planting.

[0024] Working principle: When the user is planting seeds, he first pours the seeds into the material bin 5, and the seeds enter the groove 74 of the rotating member 72 from the upper discharge port 71, and the first motor 73 and the second motor 81 are started. The first motor 73 rotates to drive the rotating member 72 to rotate in the transfer barrel 7, and drives the seeds in the groove 74 to rotate. When the groove 74 coincides with the lower discharge port 71, the seeds slide out of the groove 74 through the lower discharge port 71 and fall into the conveying pipe 6, and continue to move downward along the conveying pipe 6. At the same time, the second motor 81 rotates to drive the connecting rod 83 to perform a circular motion, and the slider 84 slides in the slide groove 86. When the slider 84 moves from one end of the slide groove 86 to the other end and continues to rotate, it drives the furrow opener 85 to rotate downward and dig a hole on the land. After the connecting rod 83 rotates one circle, the furrow opener 85 returns to the initial position, and the equipment keeps moving forward. Driven by the first motor 73 and the second motor 81, the seeds continue to slide, the furrow opener 85 continues to dig a hole, and the seeds fall into the hole, so as to achieve uniform planting of seeds.
