Detailed Description
The embodiments of the invention will be described in detail below with reference to the accompanying drawings:
interior cylinder hangs spoon formula vegetables smart volume seed metering ware, the seed metering dish axle 4 of end fixing seed metering dish 1 passes through bearing 5 rotatable assembly to both sides be equipped with in the dead eye 17 at the middle part of the interior casing 8 of mounting hole 10, bearing 5 is by bearing end cover 11 axial fixity, seed metering dish axle 4 is by being furnished with 3 axial fixings of stop collar of locating pin 9, the seed metering spoon 2 of the interior cylinder circumference equipartition form of dangling of seed metering dish 1, seed metering spoon 2 comprises hemisphere face 15 and lofting formula arc surface 16, interior casing 8 passes through screw 12 fixed shell body 7, shell body 7 inside side sets up and is from top to bottom to be the seed metering pipe 6 that reduces hourglass shape gradually, and seed inlet 13 of the lower extreme setting seed outlet 14 upper end of pipe 6 stretches into inside seed metering dish 1, and seed metering spoon 2 comprises seed metering hemisphere face 15 and lofting formula arc surface 16.
Before operation, firstly, vegetable seeds such as radish and Chinese cabbage are pretreated, oversize or undersize seeds are carefully selected and screened, the uniform and consistent sizes of the seeds are ensured, the seed discharging plate 1 of the seed discharging spoon 2 with a proper size is replaced according to the sizes of the vegetable seeds needing precision seeding such as radish and Chinese cabbage, the vegetable seeds such as radish and Chinese cabbage are placed in an inner cavity formed by the seed discharging plate 1 and the outer shell body 7, and the seed discharging device is assembled on the seeding machine through the mounting hole 10.
During operation, external power drives the seed discharging disc shaft 4 to reach a required rotating speed according to the required row spacing of vegetable seeds such as radish or Chinese cabbage, the seed discharging disc shaft 4 drives the seed discharging scoops 2 which are uniformly distributed in the circumferential direction on the inner wall of the seed discharging disc 1 to do circular motion, when the seed discharging scoops 2 move to the seed stack at the bottom of the inner cavity, the seeds enter the seed discharging scoops 2, when the seed discharging scoops 2 continue to rotate out of the seed stack, redundant seeds drop back to the seed stack again by virtue of gravity, and as the seed discharging scoops 2 which are uniformly distributed on the inner cylindrical surface of the seed discharging disc 1 adopt the structures of the hemispherical surface 15 and the lofting type arc surface 16, the phenomenon that the seeds in a cylindrical nest eye wheel type seed discharging disc collide with the seed protecting plate and the hairbrush in the seed cleaning and carrying processes due to the existence of a forced seed cleaning brush and a seed protecting plate is avoided (when the seed cleaning and carrying wheel type seed discharging disc works, the seeds in the columnar nest eye wheel type seed cleaning and seed protecting plate collide with the hairbrush, Meanwhile, the problem of seed pressing can also occur in self cylindrical cells), when the seed metering spoon 2 rotates to the position above the seed inlet 13 at the upper end of the seed metering pipe 6, seeds can fall off from the seed metering spoon 2 due to gravity, fall into the seed metering pipe 6 through the seed inlet 13, then fall out from the seed outlet 14, fall into corresponding seed ditch soil, and then are subjected to soil covering and pressing operations by other parts of the seeder. So far, the inner cylindrical surface suspension scoop type vegetable precision seed-metering device realizes the design function of preventing seeds from being damaged.
Meanwhile, the uniformly distributed seed metering scoops 2 are adopted in the inner cylindrical surface of the seed metering disc 1 of the inner cylindrical surface suspension scoop type vegetable precision seed metering device, each seed metering scoop 2 picks up one seed in the rotation process of the seed metering disc 1, the seeds in the seed metering scoops 2 are thrown into the corresponding seed ditch due to the self gravity, the plant spacing of the vegetable seeds such as radish and Chinese cabbage when being planted is ensured, and thus, the inner cylindrical surface suspension scoop type vegetable precision seed metering device meets the precision seeding requirements of different types of vegetable seeds of radish and Chinese cabbage.
