It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] like Figures 1-4 As shown in this embodiment, an agricultural planting and sowing device that facilitates row spacing adjustment includes a sowing box 1. At equal intervals, material discharge pipes 3 are installed at the bottom of the sowing box 1. Each material discharge pipe 3 is equipped with a sealing component 6. The sealing component 6 includes a U-shaped frame 601, a handwheel 602, a self-locking screw 603, a sealing plate 604, and a sliding hole 605. A material feeding component 5 is also installed in the lower part of the sowing box 1. The material feeding component 5 includes a sowing trough 501, a feeding roller 502, and a rotating shaft 503. The sealing plate 604 in the sealing component 6 is mainly used to control the opening and closing of the material discharge pipes 3. By opening two adjacent normally discharging material discharge pipes 3 and simultaneously closing the other material discharge pipes 3, the row spacing of the seeds after sowing can be controlled.

[0018] like Figures 1-4 As shown, in this embodiment, a connecting frame 4 is welded to one side wall of the seed box 1. The connecting frame 4 consists of a V-shaped rod and a connecting plate welded to the end of the V-shaped rod facing away from the seed box 1. The connecting frame 4 is mainly used to reliably connect the seed box 1 to the pin on the tractor frame. The discharge pipe 3 consists of a vertical pipe connected to the bottom of the seed box 1 and a soil-opening hook formed at the bottom of the vertical part. The vertical pipe on the discharge pipe 3 can ensure the normal feeding and sowing of crop seeds.

[0019] like Figures 1-4 As shown, in this embodiment, a sliding hole 605 is formed in the middle of one side wall of the discharge pipe 3. A sealing plate 604 is slidably installed in the sliding hole 605. A U-shaped frame 601 is welded to the outside of the discharge pipe 3 outside the sliding hole 605. The U-shaped frame 601 is mainly used to provide an installation base for the self-locking screw 603. The sealing plate 604 is mainly used to control the opening and closing of the discharge pipe 3 channel. The self-locking screw 603 is a threaded rod with self-locking threads. The self-locking screw 603 is rotatably installed in the middle of one side wall of the U-shaped frame 601. The handwheel 602 is welded to the exposed end of the self-locking screw 603, and the sealing plate 604 is threaded to the other end of the self-locking screw 603. The sealing plate 604 has a pre-reserved threaded groove at the mating part with the self-locking screw 603. Rotating the handwheel 602 can rotate the self-locking screw 603. After the self-locking screw 603 rotates, it will be driven by the thread to make the sealing plate 604 screw into the self-locking screw 603, thereby realizing the removal of the sealing plate 604 from the discharge pipe 3 and opening the corresponding discharge pipe 3 channel.

[0020] like Figures 1-4As shown, in this embodiment, the rotating shaft 503 is rotatably installed at the bottom of the seed box 1, the feeding roller 502 is welded to the middle of the rotating shaft 503, and the seeding troughs 501 are arranged in a row on the outer wall of the feeding roller 502. After the feeding roller 502 rotates, it will sequentially sow the crop seeds to the opening of the discharge pipe 3 through the seeding troughs 501, so as to realize the falling of the crop seeds. The two ends of the rotating shaft 503 extend out of the seed box 1, and the two ends of the rotating shaft 503 are connected to wheels 2. The wheels 2 are mainly used to realize the synchronous movement of the seed box 1 with the tractor frame, and at the same time realize the convenient rotation of the feeding roller 502 to feed the seeds.

[0021] The specific implementation process of this embodiment is as follows: When sowing crop seeds, firstly, according to the row spacing requirements of the crop seeds, the sealing plate 604 on the corresponding discharge pipe 3 is removed, while the other discharge pipes 3 are blocked by the corresponding sealing plate 604 and cannot discharge seeds for sowing. Then, simply connect the connecting frame 4 to the pin at the connecting block on the tractor frame, and the feeding roller 502 can rotate while the tractor drives the wheel 2 on the seeding box 1 to rotate, so that the crop seeds are sown to the corresponding discharge pipe 3 through the sowing trough 501 while the feeding roller 502 rotates, and fall and be sown through the corresponding discharge pipe 3. Since this agricultural planting sowing device can easily remove the sealing plate 604 from the corresponding discharge pipe 3 according to the actual sowing needs, the spacing between the two discharge pipes 3 that discharge normally can be adjusted, ensuring that the row spacing of the crop seeds after sowing meets the normal growth requirements of the corresponding crop, thereby improving the flexibility of the sowing device.
