The working principle of the automatic seedling feeding device of the dryland vegetable seedling transplanting machine:

The driving force drives the first sprocket 16 to rotate, drives the parallel indexing divider 4 to work, and transmits the power to the lateral shifting box assembly 5 through the second sprocket 18, the chain and the driving small sprocket 20; the rotation of the double helix shaft 23 makes the guide Block 25 moves, thereby power is transmitted to connecting shaft 28, and connecting shaft 28 drives two main support plates 29, and seedling box assembly 6 realizes the lateral movement along slide rail 14 under the effect of moving box device 3; When parallel index divider 4 When stopping work, the movement of two main support plates 29 is also suspended, and now the seedling-taking mechanism clamps the vegetable seedlings in 32 li of seedling trays. A row of seedlings in the seedling tray 32; when moving to the end, the cam 22 collides with the pressing plate 37 to cause the pressing plate shaft 38 to rotate, and the linkage block 39 fixed with the pressing plate shaft 38 presses down the handle 44, and the handle pin cylinder 50 lifts the pawl 43 When the collision force of the cam 22 to the pressing plate 37 disappeared, the handle 44 reset under the pulling force of the spring 45, and now the inner and outer rings of the one-way bearing 52 were mutually locked, and the handle 44 drove the ratchet 47 to rotate; the sprocket adjustment wheel 49 and Ratchet 47 is connected by ratchet pin shaft 48, and is connected with sprocket wheel shaft 46 by key, thereby drives large sprocket wheel 41 to rotate, and the chain pin shaft 40-1 of the topmost chain pin shaft 40-1 of the nylon chain 40 that is sleeved on the large sprocket wheel 41 stretches into seedling In the seedling disc shifting groove 30-1 of the plate 30, the seedling disc 32 is moved down one row. At this time, the ratchet 47 just turns over one tooth, and the ratchet 43 is embedded in the wheel groove of the ratchet 47 again; the seedling disc 32 moves down one row. Afterwards, the seedling case assembly 6 moves laterally in reverse, so repeatedly until the seedling-getting mechanism has taken the seedlings in the seedling tray 32 li. If the seedlings in the seedling tray 32 li are missed, and when the dryland transplanting operation has ended, the sprocket adjustment wheel 49 can be moved to disengage the ratchet pin 48 from it, and the inner and outer rings of the one-way bearing 52 are not locked. The direction rotation sprocket adjustment wheel 49 drives big sprocket 41 revolutions, thereby seedling dish 32 is withdrawn from. Two side pressing plates 56 push down the seedling dish 32 both sides, and middle pressing plate 57 pushes down the seedling dish 32 middle parts, prevents that seedling dish 32 perks.
