The working principle of the invention is as follows: when the device is used, the device is connected with a water outlet pipe of an external pressurizing device through the corrugated pipe 25, and under the action of the pressurizing device, a water source in the external water tank can enter the corrugated pipe 25, and particularly, the corrugated pipe 25 is made of rubber and can be passively bent and stretched;
the salt-tolerant solvent can be added into the water while supplementing water to the seedlings in the seedling container 2, so that the salt tolerance of the seedlings in the seedling container 2 is improved in the cultivation process;
when an external water source enters the interiors of the two groups of fixed side shells 19 and the annular sleeve 21 through the corrugated pipe 25 and the second communicating pipe 24 by the supercharging device, the water source pushes the impeller 22 to drive the rotating rod 5 to rotate, and then the rotating rod 5 drives the back shell 7 to turn over from a vertical state to a horizontal state through the two groups of connecting rods 6, so that the second spray head 13 of the telescopic water spraying frame 9 faces the seedlings;
at this time, a water source enters the first water spraying cavity 10 through the first communication pipe 23 and the connecting pipe 18, the internal pressure of the first water spraying cavity 10 is increased along with the pressurized transportation of an external water source, so that the two groups of telescopic water spraying frames 9 extend out relative to the fixed water spraying frames 8, the two groups of telescopic water spraying frames 9 are separated from shielding the first spray heads 12 in the fixed water spraying frames 8, at this time, the two groups of telescopic water spraying frames 9 and the fixed water spraying frames 8 integrally form a semicircle ring, under the action of the multiple groups of first spray heads 12 and the second spray heads 13, the water source can perform semicircle ring type spraying water supplementing on seedlings, and the other groups of fixed water spraying frames 8 and the telescopic water spraying frames 9 can form the circular ring type spraying water supplementing outside the seedlings;
specifically, a sealing cavity is formed between the two sets of fixed side shells 19 and the annular sleeve 21, and the annular sleeve 21 can rotate annularly in the two sets of fixed side shells 19, so that when the back shell 7 is turned from a vertical state to a horizontal state, the connecting pipe 18 is not influenced to drive the annular sleeve 21 to rotate, and the annular sleeve 21 and the two sets of fixed side shells 19 are in sealing sliding connection, so that the problem of water source leakage is avoided;
further, when the back shell 7 is turned to a horizontal state, the connection limiting plate 20 limits the connection pipe 18, so that the back shell 7 is limited and fixed, and because the impeller 22 and the rotating rod 5 are in friction connection, when water flow cannot drive the rotating rod 5 to rotate through the impeller, the acting force of the water pressure on the impeller 22 at the moment is larger than the friction force between the impeller and the rotating rod 5 along with the increase of the water pressure at the moment, so that the water flow drives the impeller 22 to rotate relative to the rotating rod 5, the impeller 22 cannot drive the rotating rod 5 to rotate at the moment, and the impeller 22 rotates relative to the rotating rod 5, so that the passing of the water flow cannot be influenced;
when the two groups of telescopic water spraying frames 9 extend under the action of water pressure relative to the fixed water spraying frames 8, at the moment, when the two groups of telescopic water spraying frames 9 slide along the arc-shaped guide rods 15 and stretch the return springs 17, after water spraying is finished, the external water pressure disappears, the two groups of telescopic water spraying frames 9 shrink under the action of the return springs 17, and then water in the second water spraying cavity 11 flows back to the annular sleeve 21 sequentially through the first water spraying cavity 10, the connecting pipe 18 and the first connecting pipe 23, at the moment, the water flow drives the impeller 22 and the rotating rod 5 to rotate reversely, so that the whole back shell 7 is turned from a horizontal state to a vertical state, the blocking of the fixed water spraying frames 8 and the telescopic water spraying frames 9 on the seedling containers 2 in the cultivation main body 1 is avoided, and workers can more conveniently take and put the seedling containers 2 without affecting the operation of entering or moving the cultivation main body 1;
still further, when the two sets of telescopic water spraying frames 9 shrink, the second water spraying cavity 11 pushes the water inside the first water spraying cavity 10 to enter the annular sleeve 21 through the connecting pipe 18, at this time, the acting force of the water flow acting on the impeller 22 is smaller than the friction force between the impeller 22 and the rotating rod 5, and then the water flow can drive the rotating rod 5 to rotate reversely through the impeller 22, so that the rotating rod 5 rotates reversely to drive the back shell 7 to rotate reversely from the horizontal state to the vertical state just, and the picking and placing operation of the seedling container 2 can not be influenced.
Although embodiments of the invention have been shown and described, the detailed description is to be construed as exemplary only and is not limiting of the invention as the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples, and modifications, substitutions, variations, etc. may be made in the embodiments as desired by those skilled in the art without departing from the principles and spirit of the invention, provided that such modifications are within the scope of the appended claims.
