Detailed Description
The technical solution of the present invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1-2, a self-disturbance type precision soybean seed-metering device is characterized in that: comprises a seed box 1, a front shell 2, a rear shell 3, a seed sowing port 4, a fixing frame 5, a duplex hole 6, a seed sowing wheel 7, disturbance fan blades 8, a transmission shaft 9, a seed baffle plate 10, a guide groove 11, an arc seed cavity 12 and a seed fixing plate 13. The seed box 1 is arranged on the outer side of the front shell 2 and is communicated with the front shell, and a circular hole is formed in the center of the surface of the rear shell and matched with the bottom of a regular hexagon shaft body of a transmission shaft. The center of the inner wall of the seed sowing wheel 7 is provided with a regular hexagonal hole and a limit pin hole which are matched with a regular hexagonal shaft body of the transmission shaft 9, and the seed sowing wheel is fixed by a limit pin. The outer circumferential surface of the seed sowing wheel 7 is provided with two rows of 20 compound holes 8 which are uniformly distributed along the radial direction, each compound hole 8 is composed of a seed guiding groove with a certain gradient and an arc-shaped seed cavity, and the seed guiding groove extends to the opening of the adjacent hole. The disturbing fan blades 8 are matched with the key groove and the shaft and the key at the front section of the transmission shaft 9 through a central shaft hole, and are limited and fixed by the inner wall surface of the front shell and the wall surface of a central regular hexagon hole of the seed sowing wheel.
The transmission shaft 9 is driven by power sources such as chains or motors to rotate, the seed sowing wheel 7 and the disturbance fan blades 8 are driven by the transmission shaft 9 to rotate around the axis of the transmission shaft, indoor population is disturbed along the tangential direction of the circumference due to the rotation of the disturbance fan blades 8, so that the relative movement speed between the compound type holes 6 and the population is reduced, and seeds fall into the guide grooves of the compound type holes 6 and gradually enter the seed cavities to complete seed filling.
The compound type hole 6 structure is composed of a seed guiding groove 11 and an arc-shaped seed cavity 12, the seeds are guided to the opening of the compound type hole in sequence by the seed guiding groove 11 to be regularly arranged in the seed filling process, two seeds nearest to the seed cavity firstly enter the arc-shaped seed cavity, one seed is just separated from the rest seeds in the seed cavity along with the rotation of the seed sowing wheel, and the rest seeds fall from the seed cavity under the action of self gravity to finish the seed cleaning process.
The compound type hole 6 moves to the area surrounded by the seed baffle plate 10, the seeds in the arc seed cavity slide down from the seed cavity under the action of self gravity and centrifugal force and move to the tail end of the guide groove of the type hole, and the seed to be thrown keeps a stable state under the action of wall support force, self gravity and centrifugal force because the seed fixing plate 13 at the tail end of the guide groove and the bottom of the type hole form a 90-degree included angle, and the seeds are discharged from the seed sowing port.
The working principle of the invention is shown in fig. 8, and the working process of the seed sowing device is roughly divided into four areas, namely a seed charging area I, a seed cleaning area II, a seed protecting area III and a seed feeding area IV. The seeds enter the seed metering device and are firstly filled in the seed filling area, the seeds in the seed filling area enter the seed holes in the shaped holes under the action of self gravity and centrifugal force to be regularly arranged, and disturbance fan blades are added in the seed metering device to ensure that the disturbance of the seed group is severe, so that the inclination angle of the seed group is larger, the range of the seed filling area is enlarged, and the seed filling success probability of the seed filling area is improved. The design of the profile hole is provided with a seed filling guide groove, so that the profile hole passing through the seed filling area guides seeds to fill the seeds in the seed filling area, the seed filling success rate of the seed sowing device is ensured, and the working speed of the seed sowing device is also improved. The seeds in the seed cavity after the successfully filled holes pass through the seed cleaning area are regularly arranged to wait for seed cleaning, and the seeds outside the seed holes of the seed holes before entering the seed protecting area fall off from the seed holes under the action of self gravity, so that the seed cleaning effect is achieved. Then only one seed in each hole is ensured before entering the seed protection area. The seeds entering the seed protection area are kept in a stable state by abutting against the seed fixing plate under the action of self gravity and centrifugal force until entering the seed discharging area and being discharged from the seed discharging port.
The foregoing embodiments are merely illustrative of the principles and main features of the present invention, and are not intended to limit the scope of the present invention, and those skilled in the art should make equivalent changes or modifications to the technical solutions of the present invention without departing from the technical spirit of the present invention.
