[0002] Automatic seeding is a process that uses modern agricultural equipment and technology to achieve automatic transmission, storage, supply and precise seeding of seeds. With the continuous development of technologies such as artificial intelligence and the Internet of Things, automatic seeding machines are also developing in the direction of automation, digitization and multi-functionality. Automatic seeding machines use electronic control systems and mechanical transmission systems to accurately measure, position, place and cover seeds, greatly improving the efficiency and accuracy of seeding.

Feeding and sowing are separated and controlled by separate control systems, which makes it easy to miss seeds. To this end, we provide an automatic seed feeder for automatic seed drills to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0026] See also Figure 1-6 The utility model is an automatic seeding machine seed automatic feeding device, comprising a moving component 1, a feeding component 2 and a sowing component 3. Specifically, the feeding component 2 is fixedly connected to the moving component 1, and the feeding component 2 comprises a rotatable feeding column 201 and a rotatable cleaning brush 202. The end of the cleaning brush 202 is in contact with the side surface of the feeding column 201. The side surface of the feeding column 201 is provided with a plurality of storage grooves 203. The size of the storage grooves 203 can accommodate a certain number of seeds. The sown seeds are granular, and the seeds fall into the storage grooves 203. The rotation of the feeding column 201 drives the seeds in the storage grooves 203 to move toward the sowing component 3.

[0027] Furthermore, the sowing component 3 is slidably matched with the moving component 1, and the sowing component 3 is fixedly connected to the material transfer column 201. The sowing component 3 includes a transmission disc 301 fixedly connected to the material transfer column 201 through a support shaft, a sowing support frame 302, and an opening and closing frame 303 symmetrically arranged for rotation. When the material transfer column 201 rotates, the transmission disc 301 is driven to rotate synchronously.

[0028] The operation process of this embodiment is as follows: the seeds to be sown fall into the storage trough 203 under the action of gravity, the transfer column 201 rotates to drive a certain amount of seeds to move synchronously, and at the same time, the transmission disc 301 rotates synchronously with the transfer column 201, driving the sowing support frame 302 to move up and down, when the sowing support frame 302 moves downward and the opening and closing frames 303 separate from each other, the seeds fall into the soil pit for sowing. Specific embodiment 2

[0030] See also Figure 1-6 On the basis of the first specific embodiment, specifically, the moving assembly 1 includes a first support plate 101 and a second support plate 102 which are symmetrically arranged. The first support plate 101 and the second support plate 102 are fixedly connected via a plurality of support columns, and the first support plate 101 is located directly above the second support plate 102; a first through hole is provided on the surface of the first support plate 101, and a second through hole is provided on the surface of the second support plate 102; a moving handle 103 is fixedly connected to the upper surface of the first support plate 101, and the second support plate 102 is rotatably connected to a plurality of moving wheels 104 via ear plates.

[0031] Furthermore, the feeding assembly 2 also includes a quantitative support frame 204 fixedly connected to the upper surface of the first support plate 101, and a feed hopper 205 is fixedly connected to the upper surface of the quantitative support frame 204. The feed hopper 205 is fixedly connected to two inner side walls thereof. Seeds to be sown are put into the feed hopper 205 and blocked on the two partition baffles 206. A discharge port is formed between the two partition baffles 206. The width of the discharge port is consistent with the diameter length of the storage trough 203, so that a quantitative amount of seeds falls into the storage trough 203, and the remaining seeds fall down one by one under their own gravity and the hindrance of the partition baffles 206. A transmission frame 207 fixedly connected to the inner wall of the first through hole is fixedly connected to the lower surface of the quantitative support frame 204, and a transmission slide groove 208 is opened on one side of the transmission frame 207.

[0032] Furthermore, the material transfer column 201 and the cleaning brush 202 are symmetrically rotatably connected between the two opposite inner walls of the quantitative support frame 204 through the first rotating shaft. The two first rotating shafts pass through one end of the quantitative support frame 204 and are fixedly connected with a transmission gear 209. The two transmission gears 209 are meshed with each other. The two transmission gears 209 can rotate synchronously and thus drive the material transfer column 201 and the cleaning brush 202 to rotate synchronously in the opposite direction. A driving motor 210 is fixedly installed on the side of the quantitative support frame 204 away from the transmission gear 209. The output shaft of the driving motor 210 is fixedly connected to the cleaning brush 202. The driving motor 210 is used to drive the cleaning brush 202 to rotate, and the corresponding transmission gears 209 rotate synchronously.

[0033] The operation process of this embodiment is as follows: when it is necessary to control the seed discharge, the drive motor 210 is started to drive the cleaning brush 202 to rotate, and the transmission gear 209 corresponding to the cleaning brush 202 rotates synchronously. Under the mutual meshing action of the two transmission gears 209, the two transmission gears 209 rotate synchronously in the opposite direction, thereby driving the material transfer column 201 to rotate. When the storage trough 203 on the material transfer column 201 rotates to just below the discharge port formed between the two partition baffles 206, the seeds fall into the storage trough 203 under the action of gravity. As the material transfer column 201 continues to rotate, due to The material transfer column 201 fits with the end of the partition baffle 206, and the surrounding side of the material transfer column 201 prevents the seeds from continuing to fall. At the same time, the material storage trough 203 drives the quantitative seeds to move synchronously with the continued rotation of the material transfer column 201. When it rotates to a certain angle, the material storage trough 203 contacts the end of the cleaning brush 202. Since the cleaning brush 202 and the material transfer column 201 rotate synchronously in the opposite direction, the cleaning brush 202 cleans the material storage trough 203 during the rotation process to prevent seeds from remaining or adhering to the inner wall of the material storage trough 203, thereby allowing the quantitative seeds to fall into the transmission frame 207. Specific embodiment three

[0035] See also Figure 1-6 On the basis of the first and second specific embodiments, specifically, the sowing support frame 302 is slidably arranged inside the second through hole, the sowing support frame 302 can slide up and down along the inner wall of the second through hole, and the sowing support frame 302 is sleeved on the outside of the transmission frame 207, and the opening and closing frame 303 is rotatably connected to the lower end of the sowing support frame 302 through the second rotating shaft. In the initial state, the two opening and closing frames 303 are fitted together to remain airtight, and an inner side wall of the sowing support frame 302 is fixedly connected to a limiting column 304 that slides with the transmission slide groove 208.

[0036] Furthermore, a transmission link 305 is rotatably connected to a side of the sowing support frame 302 away from the transmission slide groove 208, and the other end of the transmission link 305 is rotatably connected to the eccentric position of the transmission disc 301. When the transmission disc 301 rotates, it drives the first adjustment link 306 to move synchronously, so that the first adjustment link 306 pulls the sowing support frame 302 to move up and down; the first adjustment link 306 is fixedly connected to the side surface of the second rotating shaft, and the two first adjustment links 306 are symmetrical to each other, so that when the first adjustment links 306 rotate, they drive the two second rotating shafts to rotate synchronously in opposite directions, one end of the first adjustment link 306 is rotatably connected to the second adjustment link 307, and one end of the second adjustment link 307 is rotatably connected to the inner wall of the transmission frame 207. When the sowing support frame 302 moves downward, the transmission frame 207 pulls the second adjustment link 307, thereby driving the first adjustment link 306 to rotate.

[0037] The operation process of this embodiment is as follows: when there is a certain amount of seeds in the storage trough 203 and the transfer column 201 rotates, the transmission disc 301 is driven to rotate synchronously. Since one end of the transmission connecting rod 305 is rotatably connected to the eccentric position of the transmission disc 301, the transmission connecting rod 305 pulls the transmission connecting rod 305 as the transmission disc 301 rotates, so that the transmission connecting rod 305 drives the sowing support frame 302 to slide downward along the inner wall of the second through hole, and at the same time, the limit column 304 slides downward along the inside of the transmission slide groove 208. In this process, since the transmission frame 207 is fixed in position, the second adjusting connecting rod 307 is pulled, and the first adjusting connecting rod 306 rotates, so that the second rotating shaft rotates, driving the opening and closing frame 303 to rotate, so that the two opening and closing frames 303 rotate synchronously in opposite directions, and the end of the sowing support frame 302 is opened, thereby realizing that the opening and closing frame 303 is opened while moving downward, and the certain amount of seeds fall to the ground.
