Description

Technical Field

[0001] The present invention relates to the technical field of grass seed pelleting, and particularly relates to a pelleting device for long grass seeds and an operation method thereof. Background Art

[0002] A pelleting device uses soluble glue to bond a filler and some additives beneficial to seed germination on the surface of seeds, making the seeds into smooth, spherical particles with the same shape and size, and processing them into pellet shapes for easy sowing and storage.

[0003] As disclosed in a utility model patent of China for a pelleting device for plateau ecological grass seeds (Publication No.: CN218218231U), it includes an equipment frame. A slanting box is fixedly connected to the bottom end of the equipment frame. A feeding funnel is fixedly connected to the top end of the equipment frame, and the feeding funnel is communicated with the slanting box.

[0024] Step 5, as the mixing cylinder simultaneously performs reciprocating swinging, reciprocating rotating, and reciprocating jacking, plus the reciprocating self-rotation of the stirring rods, the long-grain grass seeds, soluble glue, filler, and granulation auxiliary materials are uniformly mixed to form granulated long-grain grass seeds. Then, stop the first motor and the second motor in sequence, open the threaded plug cover, and take out the formed granulated long-grain grass seeds.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

The second gear (38) meshes and rotates self-revolvingly along the inner arc-shaped rack (39), and drives the stirring shaft (36) and a plurality of stirring rods (37) to rotate reciprocally self-revolvingly, and mixes and stirs the long-grain grass seeds, soluble glue, filling material, and pelletizing auxiliary materials through the stirring rods (37). Step 4: Start the first motor (13). The motor shaft of the first motor (13) drives the fixed disk (14) and the four trapezoidal stoppers (15) to rotate synchronously. Under the limiting action of the trapezoidal stopper (15) and the pulley (17), the jacking slide rod (16) is driven by the pulley (17) to reciprocate and jack along the positioning slide hole, synchronously driving the jacking plate (2) and the mixing cylinder (32) to reciprocate and jack, and maintaining a balanced state under the action of the four tension springs (18). Step 5: As the mixing cylinder (32) simultaneously performs reciprocating swinging, reciprocating rotation, and reciprocating jacking, combined with the reciprocating self-rotation of the stirring rod (37), the long grass seeds, soluble glue, filler, and pelleting auxiliary materials are evenly mixed to form pelleted long grass seeds. Then, stop the first motor (13) and the second motor (28) in sequence, and open the threaded plug cover (19) to take out the formed pelleted long grass seeds.
