As shown in fig. 4 and 5, when the main lever 31 is released, the tension spring 313 contracts, the main lever 31 and the auxiliary lever 32 are pulled to move upwards, the sliding rod 38 slides to the bottom of the hollow part of the auxiliary lever 32 along the hollow part of the auxiliary lever 32, the pulley 39 slides to the bottom of the pulley groove 310 along the annular track 315 formed by the left side of the spring piece 311 and the pulley groove 310, at this time, the pulley 39 slides to the right side of the pulley groove 310 after passing through the lower end of the spring piece 311, and the rightward displacement of the pulley 39 drives the rotating lever 34 to rotate clockwise, drives the auxiliary lever 32 to slide leftwards along the sliding groove 37, so that the auxiliary lever 32 is meshed with the gear 33; at this time, the string 44 is not stressed, the compression spring 43 is stretched to a natural state, and downward force is given to the triangular plate 42, so that the triangular plate 42 returns to a horizontal state, and the hole digging plate 41 is closed; this is state ii.
The sowing gun is switched between the state I and the state II once, the gear 33 rotates for half a circle to drive the seed separating wheel 24 to rotate, one seed in the groove of the seed separating wheel 24 falls into the shell 1, the seed falls into the opposite groove from the precise seed separating device 22 again, the hole digging plate 41 is stressed to open, the seed falls from the hole digging plate, and two procedures of hole digging and sowing are completed. The driving pulley 25 drives the driven pulley 28 and the vibration generator 29 to rotate, so that the precise seed separator 22 vibrates, and seeds in the precise seed separator slide down and are not blocked.
Example 2
A row gun for a disc-shaped seed sowing gun, which is obtained by connecting 9 disc-shaped seed sowing guns provided in the embodiment 1 into a row. The disc-shaped seed sowing gun and the row gun can sow a plurality of holes of the seedling raising hole tray at one time.
Example 3
A method for using a disk-shaped seed sowing gun includes loading seeds into a seed containing box, inserting the sowing gun into a seedling tray substrate, manually pressing down a main rod, lifting the sowing gun, and loosening the main rod to finish one-time sowing.
The foregoing is merely a partial embodiment of the present invention, and any substitutions and modifications made on the basis thereof are intended to be included in the scope of the present invention.
