fig. 2 is a schematic top view of an embodiment of the present invention;
fig. 3 is a schematic structural view of the negative pressure seed selection device of the present invention.
Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
Example (b):
referring to fig. 1, the negative pressure seed selection device of the garlic planter according to the present embodiment includes a housing 1 with an open top and a negative pressure seed selection device.
The middle part of casing 1 is fixed with baffle 2, the rear side of baffle 2 is for storing up kind of a storehouse, and the front side of baffle 2 is for selecting kind of a storehouse. Two through openings for holding garlic seeds to enter the seed selection bin from the seed storage bin are symmetrically formed in the partition plate 2, and a bottom plate of the seed storage bin is an inclined plane with a front bottom and a rear height, so that the garlic seeds can roll forwards and enter the seed selection bin through the through openings.
The negative pressure seed selection device is arranged in the seed selection bin and comprises a negative pressure barrel 3 and seed suction discs 4 (which are in one-to-one correspondence with through holes in the partition plate 2) symmetrically arranged at two ends of the negative pressure barrel 3, wherein the seed suction discs 4 and the negative pressure barrel 3 are of an integral structure and are communicated with the inner cavity of the negative pressure barrel 3. Two ends of the negative pressure cylinder 3 are respectively assembled on the side walls of two sides of the seed selection bin through bearings, wherein one end of the negative pressure cylinder is closed and fixedly connected with a power input shaft 9, and the other end of the negative pressure cylinder is opened and provided with a negative pressure connecting nozzle 7; the negative pressure connecting nozzle 7 is arranged on the opening end of the negative pressure barrel 3 through a sealing bearing piece, and the outer end of the negative pressure connecting nozzle is provided with a negative pressure pipe connecting nozzle 8 used for connecting a negative pressure pipe. The two side surfaces of the two seed sucking discs 4 are uniformly provided with a plurality of garlic sucking holes 5 along the circumferential edge, and a garlic supporting plate 6 is fixedly arranged at each garlic sucking hole 5. The parts of the front side wall of the seed selection bin corresponding to the seed suction disc 4 are respectively fixed with a plugging plate 10 for plugging garlic sucking holes 5 on the two side surfaces of the seed suction disc 4.
The working process of the negative pressure seed selection device of the garlic planter is briefly described as follows:
the power input shaft 9 is connected with the power output end of the driving device in a transmission way, the negative pressure pipe joint nozzle 8 is connected with a negative pressure pipe, and the other end of the negative pressure pipe is connected with a negative pressure fan. The driving device drives the negative pressure cylinder 3 to rotate, and then drives the two seed sucking discs 4 to rotate, and the negative pressure connecting nozzle 7 is arranged on the opening end of the negative pressure cylinder 3 through the sealing bearing part, so that the negative pressure connecting nozzle 7 cannot rotate along with the negative pressure cylinder 3 while the air tightness is ensured. The negative pressure fan is started to generate negative pressure in the inner cavities of the negative pressure cylinder 3 and the seed sucking disc 4, and each garlic sucking hole 5 generates adsorption force.
The selected garlic seeds are guided into the seed storage bin, the garlic seeds enter the seed selection bin through the through hole, the garlic seeds near the seed suction disc 4 are shoveled by the garlic supporting plate 6, and are adsorbed on the side wall of the seed suction disc 4 by the adsorption force of the garlic sucking holes 5 and rotate along with the seed suction disc; when the garlic sucking holes 5 with the garlic seeds are rotated to be overlapped with the plugging plates 10, the plugging plates 10 are inserted between the garlic seeds and the garlic sucking holes 5, the garlic seeds lose adsorption force, are separated from the seed sucking discs under the action of self gravity, fall on a garlic seed conveying belt of the garlic planter, and enter the next link.
