specific Embodiment approach 1

[0040] Specific implementation mode one: as Figure 1-Figure 3 and Figure 11 As shown, this embodiment discloses an electric drive duplex seed metering device, including a spacer 1 , a left seed metering unit 2 , a left seed filling unit 3 , a right seed metering unit 6 and a right seed filling unit 7 The left and right end faces of the spacer 1 are circular, and the left and right ends of the spacer 1 are respectively provided with a circular negative pressure chamber, the left side seeding unit 2, the left side seed filling unit 3, the right side The seed-discharging unit 6 and the right-side seed-filling unit 7 are centered on the spacer 1 and arranged in a mirror-image symmetrical structure, and are installed on the left and right ends of the spacer 1 respectively, and the left-side seed-filling unit 3 and the right-side seed-filling unit 7 Located on the outside of the left side seeding unit 2 and the right side seeding unit 6 respectively, the top of the spacer 1 is pr...

specific Embodiment approach 2

[0041] Specific implementation mode two: as Figure 1-Figure 3 As shown, this embodiment is a further description of the first embodiment, and the appearance of the spacer 1 in a side view is a 'V'-shaped structure with a wide top and a narrow bottom.

[0042] There are two reasons for adopting the 'V'-shaped structure design: one is that the top of the seed meter needs to place the stepper motor 231, the motor mounting plate 232 and other parts, and its minimum width is 68mm; and the bottom of the seed meter is equipped with two Set the seed drop ports of the seed metering unit, the two seed drop ports should not be too far apart, otherwise it is difficult to ensure that the discharged seeds are on the same straight line. The second is that the bottom of the seed meter is equipped with a boot-type opener. The width of the top opening of the opener must match the bottom of the seed meter. If the width of the bottom of the seed meter is too large, it will cause interference and...

specific Embodiment approach 3

[0043] Specific implementation mode three: as figure 2 , image 3 As shown, this embodiment is a further description of specific embodiment 1 or 2. The spacer 1 is a cylinder-like body, and there is an included angle of 8.4° between the left and right end surfaces of the spacer 1 .

Abstract

The invention discloses an electrically-driven duplex seed metering device, and belongs to the field of agricultural machinery. The electrically-driven duplex seed metering device comprises a spacer, a left-side seed metering unit, a left-side seed filling unit, a right-side seed metering unit and a right-side seed filling unit; the end faces of the left and right sides of the spacer are round, a round negative-pressure cavity is formed in each of the end faces of the left and right sides of the spacer, and the left-side seed metering unit, the left-side seed filling unit, the right-side seed metering unit and the right-side seed filling unit are arranged in a mirror symmetry structure by taking the spacer as the center and are mounted on the left and right sides of the spacer respectively; and a stepping motor and negative-pressure pipe holes communicating with the negative-pressure cavities of the spacer are arranged at the top of the spacer. Compared with the prior art, the technical scheme that the two seed metering devices work in parallel is adopted, so that the bottleneck of the operation speed caused by seed cleaning and seed changing links in a single seed metering device operation mode can be thoroughly solved, the operation efficiency can be greatly improved, and the operation quality can be improved. The electrically-driven duplex seed metering device is suitable for research, development, upgrading and reconstruction of special plot seeders for breeding crops such as corn, soybeans and the like.

Description

technical field [0001] The invention relates to a seed metering device, in particular to an electric-driven double-connected seed metering device applicable to plot seeders, and belongs to the field of agricultural machinery. Background technique [0002] The plot seeder is a special agricultural machine used in the breeding industry. Before operation, it is necessary to divide the plot to be sown into multiple small plots (that is, plots) with equal areas. The size of the plot depends on the variety of seeds to be sown and the actual breeding needs. Depending on the plot, usually the plots where corn is sown are 5 meters long and the ridge width is 65 cm. There is a 1-meter-long interval between each plot. After the sowing operation in this plot is completed, when passing through the interval area, the remaining seeds in the seed meter (in order to ensure the seed filling effect, the number of seeds put in should be 10% more than the actual sowing amount) should be cleared ...
