Embodiment 1

[0035] This embodiment provides a kind of large-diameter community seeder chain row type automatic seeding device, such as figure 1 , Figure 13 Shown, comprise the mounting frame 1 that is fixed on the planter, the bottom of mounting frame 1 is provided with inoculation hopper 7 along longitudinal direction, the seed outlet 73 of inoculation hopper 7 is connected with the seed meter of planter through guide tube, falls into inoculation The seeds in the bucket 7 will directly flow into the seed meter through the guide pipe, and be sown in the land by the seed meter.

[0036] like Figure 1-Figure 6 As shown, the installation frame 1 is also provided with a seed storage device and a lever opening and closing device. The seed storage device includes a chain transmission mechanism 2 and a storage box 3; the chain transmission mechanism 2 is arranged in parallel above the inoculation bucket 7, and the chain The row transmission mechanism 2 includes a driving shaft 22, a driven s...

Embodiment 2

[0046] Embodiment 2 is similar to Embodiment 1, and the difference is that the structure of the driving mechanism of the driving rod is different, such as figure 1 , image 3 As shown, the lever drive mechanism includes a lever drive motor 421 and a vertical drive shaft 422, the lever drive motor 421 is fixed on the mounting frame 1 by bolts, and the vertical drive shaft 422 is fixed in rotation on the mounting frame on the rear side of the inoculation hopper , and the vertical driving shaft 422 is connected to the driving rod driving motor 421 through a transmission chain. When the rod driving motor 421 is working, it will drive the vertical driving shaft 422 to rotate through the transmission chain. There are many ways to fix the vertical driving shaft 422. For example: the left and right ends of the vertical drive shaft 422 are matched with the bearing housing 11, and the bearing housing 11 is fixed on the mounting frame 1 by bolts; The drive sprocket is set in the suit, a...

Embodiment 3

[0048] Embodiment 3 is similar to Embodiment 2 and is not discussed, and the difference is that Figure 7-9 As shown, the inside of the seed storage box 3 box body 31 is longitudinally divided into 4 independent seed storage chambers 36, and different or the same kinds of seeds can be placed in the 4 seed storage chambers 36 according to requirements during use. The left and right side walls of the opening of the upper end of the seed chamber 36 are symmetrically glued with guide blocks 37, the guide blocks 37 are in the shape of a right triangle, and the seed box cover 33 is provided with three open grooves 38 at intervals along the longitudinal direction, and the open grooves 38 Respectively located between the corresponding adjacent two seed storage chambers 36, when the torsion spring hinge 31 drives the seed box cover 33 to rotate clockwise around the rotating shaft of the torsion spring hinge to close the seed storage box when the torsion spring hinge 31 is not stressed, ...

Abstract

The invention discloses a chain grate type automatic seed feeding device of a large-grain size plot seeder. The automatic seed feeding device comprises a mounting frame fixed onto the seeder; the bottom part of the mounting frame is provided with a seed receiving bucket; a seed exit of the seed receiving bucket is connected with a seed-metering device of the seeder through a guide tube; the mounting frame is further provided with a seed storage device and a shift lever opening and closing device; the seed storage device includes a chain grate delivery mechanism and seed storage boxes; and thechain grate delivery mechanism is arranged in parallel above the seed receiving bucket. The automatic seed feeding device is simple in structure, reasonable in design and convenient to use, can realize automatic feeding of large-grain size seeds, and does not need to stop during seed feeding, thus increasing the work efficiency, and not only can different kinds of seeds be provided as needed during seed feeding, but also the breakage rate of the seeds is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural seeding machinery, and in particular relates to a chain-type automatic seeding device for large-diameter plot seeders. Background technique [0002] The plot seeder is a special seeder used for cultivating new varieties and conducting field experiments such as variety comparison tests. Compared with manual sowing, the plot seeder has the advantages of uniform sowing, sowing rate, and sowing depth, and high seedling quality; at the same time, it reduces labor intensity, helps reduce test errors, and improves test accuracy. [0003] At present, with the rapid development of the two breeding technologies in my country, the research and development of related breeding equipment is relatively lagging behind, especially the research on automatic seeding devices, especially for large-size seeds, such as: soybeans, peanuts, corn etc., the existing sowing equipment has a complex structure, poor seed d...
