The fastening nut 306 is screwed on the bolt 316 on the lower side of the lower synchronous lifting plate 307b, so that the fastening nut 306 abuts against the lower side of the lower synchronous lifting plate 307b, thereby realizing the fixed connection between the lower synchronous lifting plate 307b and the upper synchronous lifting plate 307a, and the installation is convenient.

[0058] The lifting rotating shaft 308 drives the upper synchronous lifting plate 307a and the lower synchronous lifting plate 307b connected together to move through the synchronous lifting sleeve 313, and the upper synchronous lifting plate 307a and the lower synchronous lifting plate 307b simultaneously drive the several seed discharge lifting connection parts and the material discharge lifting connection parts 213a on the front and rear sides to move. When the lifting rotating shaft 308 rotates and moves up to the set height, the upper ends of the lifting seed sleeve 216 and the lifting material sleeve 213 are respectively inserted into the seed discharge box 102 and the material box 103, at this time, the stirring shaft 205 rotates in the opposite direction, and the lifting rotating shaft 308 rotates and moves up to the set height. The rotating shaft 308 rotates in the opposite direction and moves downward, and the lifting rotating shaft 308 drives the lifting seed sleeve 216 and the lifting material sleeve 213 to move downward. When the lifting seed sleeve 216 and the lifting material sleeve 213 move down to the initial position, that is, the bottom of the lifting seed sleeve 216 and the lifting material sleeve 213 are respectively flush with the lower sides of the seed sleeve 201 and the discharge sleeve 212, the stirring shaft 205 rotates in the opposite direction again, and the lifting seed sleeve 216 and the lifting material sleeve 213 move up again. Repeat the above actions to make the lifting seed sleeve 216 and the lifting material sleeve 213 perform cyclic reciprocating linear motion in the height direction.

[0059] During operation, the stirring shaft 205 is rotated to drive the active bevel gear 310 to rotate. The active bevel gear 310 drives the rotating sleeve 312 to rotate through the driven bevel gear 311 and the transmission part 309. The rotating sleeve 312 drives the rotating lifting shaft to rotate and lift. The rotating lifting shaft drives the synchronous lifting module 307 to move in the height direction through the synchronous lifting sleeve 313. The synchronous lifting module 307 drives the lifting seed sleeve 216 and the lifting material sleeve 213 to lift. When the lifting seed sleeve 216 and the lifting material sleeve 213 are respectively extended into the seed box 102 and the material box 103, the seeds in the seed box 102 and the matrix in the material box 103 are loosened, which promotes the seeds and the matrix to fall. At the same time, the inner walls of the seed sleeve 201 and the material sleeve 212 are prevented from being blocked, and the seeds and The matrix discharge is smoother, and the materials discharged from the seed discharge sleeve 201 and the material discharge sleeve 212 slide into the intermediate mixing shell body 202a along the first sliding shell body 202b and the second sliding shell body 202c respectively. At the same time, the stirring shaft 205 drives the stirring sleeve 215 to rotate, and the stirring blade 215a stirs the seeds and the dry matrix to mix the seeds and the dry matrix. The seeds wrapped with the matrix enter the electric discharger 203 through the discharge port and the feed port in turn. The electric seed discharger discharges the mixed materials in a controllable manner, controls the rotation direction of the stirring shaft 205, and makes the stirring shaft 205 reciprocate, driving the lifting seed sleeve 216 and the lifting material sleeve 213 to do reciprocating linear motion in the height direction, and the seeds and the matrix fall from the box more easily.
