Detailed Description

The invention will be described in further detail with reference to the following drawings and specific embodiments:

as shown in fig. 1, 2 and 3. The seed taking box 1 is integrally placed at the lower left part of the mechanism, and garlic seeds are taken when the seed taking spoon 7 moves to the lowest part. The transmission mechanism 5 is powered by a big gear 9 and a small gear 10, and the crawler belt 6 moves under the action of the gears, so that the seed taking spoon 7 is driven to move. The conical bowl 8 is positioned below the seed-taking spoon 7, and when the seed-taking spoon 7 is opened, garlic seeds fall into the conical bowl 8. The disc 4 rotates as a driving part to drive the plate 3 to slide, so that the three-layer connecting rod 2 moves to control the opening and closing of the conical bowl.

As shown in fig. 2 and 4. The seed taking spoon is designed according to the size of garlic seeds, in the mechanism, the seed taking spoon is divided into a left half part 12 and a right half part 11, wherein the left half part 12 of the seed taking spoon is connected with a short rod 13, the right half part 11 of the seed taking spoon is connected with a long rod 14, the short rod 13 penetrates through a circular ring 19, the short rod 13 can rotate in the circular ring 19, and a spring 11 is arranged between the two rods. A round bar 16 welded to the long bar passes through the short bar 13. The ring 19 is fixed with the crawler belt 6, the ring 19 moves along with the crawler belt 6, and the seed taking spoon short rod 13 passing through the ring 19 is driven, so that the seed taking spoon moves. During the movement of the seed taking spoon, the spring 15 is at the limit of the natural state, and the left half part 12 of the seed taking spoon is tightly closed with the right half part 11 of the seed taking spoon. When the seed taking spoon moves above the cam 17 and the cam is in pushing movement, the sliding block 18 reaches the highest position, the short rod 13 is not influenced to continue to move along with the crawler belt 6, the long rod 14 is blocked by the sliding block 18 to stop moving, the long rod 14 and the short rod 13 increase by taking the round rod 16 as a supporting distance, the seed taking spoon is opened, garlic seeds fall off, and the spring 15 is in a stretching state. The cam 17 continues to rotate, and enters a return stroke state, the slide block 18 descends, the blocked long rod 14 moves back to the original state under the action of the pulling force of the spring 15, and the seed taking spoon is closed.

As shown in fig. 2 and 5. The connection among the first layer of conical bowl 26, the second layer of conical bowl 27 and the third layer of conical bowl 28 is similar to that of a seed taking spoon, the two rods of the conical bowls are the same in length, and a round rod 29 penetrates through the two rods. In the natural state, the first layer of conical bowl 26 is in the closed state, the second layer of conical bowl 27 is in the open state, and the third layer of conical bowl 28 is in the closed state. The disc rotates as a driving member and a groove 20 is designed on the disc. The roller 22 moves along the groove 20. In the rotation of the disk, the long plate 23 rotates around the shaft 21 as a rotation center according to the movement of the roller 22, so that the connecting rod 24 moves the three-layer plate 25. The three rods of the three-layer plate 25, the long block 30, are fixed relative to the round bar 29, so that the round bar 29 moves when the three-layer plate 25 moves. The left half parts of the first layer of conical bowl 26 and the third layer of conical bowl 28 are fixed, and the right half parts move along with the round rod 29; the right half of the second layer of conical bowls 27 is fixed and the left half follows the movement of the circular rod 29. When the long plate 23 rotates anticlockwise, the three-layer plate 25 moves rightwards, the right half parts of the first-layer conical bowl 26 and the third-layer conical bowl 28 move rightwards, the conical bowls are opened, the left half part of the second-layer conical bowl 27 moves rightwards, the conical bowls are closed, and all levels of staggered opening and closing of the conical bowls are achieved. When the long plate 23 rotates clockwise, the three-layer plate 25 moves leftwards, and the cone bowls of all the stages are restored to the original state. Under the action of the conical bowl angle, the angle between the bulbil and the ground is gradually increased, and the vertical seeding is finally realized.
