Abstract
The seed box bottom is provided with a seed outlet, the outer side of the seed box bottom is connected with a sleeve, the sleeve is provided with a seed inlet connected with the seed outlet, a seed shaft is arranged in the sleeve, the outer surface of the seed shaft is fixedly provided with a spiral blade, two ends of the seed shaft extend out of the sleeve, the sleeve is provided with a group of seed outlets, the positions, above the seed outlets, in the seed box are respectively and correspondingly provided with a protective cover, and the protective cover surrounds the outer sides of the seed shaft and the blade and shields the seed outlets from above. When the seeder adopting the seed metering device provided by the invention is used for seeding, seeds are placed in the seed box, so that after the seed metering shaft is driven by the transmission mechanism to rotate, the seeds are continuously conveyed into the shield by the blades in the rotation of the seed metering shaft, and the seeds can be continuously and smoothly discharged through the seed outlet. In the seed metering device, the seed is conveyed by adopting the seed metering shaft and the spiral blades, so that the seeds can be reliably discharged.
Description
Technical Field
The invention relates to a seed metering device in agricultural machinery, in particular to a seed metering device which can adapt to various types of seeds.
Background
Crop or other crop seeds can generally be classified as either granular or non-granular. The existing seed metering devices in various seed sowing machines are generally designed according to granular seeds, and the seed metering devices can be used for continuously and uniformly discharging the granular seeds ideally. For non-granular seeds, such as seeds of some Chinese herbal medicines (eucommia seeds and the like), the ideal discharge of the existing various seed metering devices is difficult to realize. At present, for non-granular seeds, the adopted sowing mode is artificial sowing, and thus the defects are that: the labor intensity is high, the sowing uniformity is poor, and the production efficiency is low.
Disclosure of Invention
The invention aims to provide a multi-type seed sowing device which can realize ideal seed sowing for various types of seeds.
In order to achieve the above purpose, the present invention adopts the following scheme: the utility model provides a multi-type seed metering device, it has seed case, seed case bottom is opened there is a seed outlet, connect in seed case bottom outside has a sleeve, open on the sleeve has a seed inlet, seed inlet and seed outlet meet, be equipped with the seed shaft in the sleeve, the outward appearance of seed shaft is fixed with and is the blade that is the heliciform, the sleeve is stretched out at the both ends of seed shaft, open on the sleeve has a set of seed outlet, the position that the seed incasement is located each seed outlet top corresponds respectively and is fixed with the guard shield, the guard shield encloses in the outside of seed shaft and blade to shelter from seed outlet from the top.
The seeding machine adopting the seeding device provided by the invention can be used for placing seeds into the seed box when seeding operation, so that the seeds can be continuously and smoothly discharged through the seeding opening by continuously conveying the seeds into the shield by the blades in the rotation of the seed shaft after the seed shaft is driven to rotate by the transmission mechanism. In the seed metering device, the seed is conveyed by adopting the seed metering shaft and the spiral blades, so that various types of seeds can be reliably discharged.
The invention has reasonable structure and reliable performance, has good seed discharge continuity and uniformity, can be used for discharging granular and non-granular seeds, and is especially suitable for discharging the non-granular seeds.

FIG. 2 is a cross-sectional view A-A of FIG. 1;
FIG. 3 is a top view of FIG. 1;
fig. 4 is a B-B cross-sectional view of fig. 3.
Detailed Description
The invention is further described below with reference to examples and figures.
See fig. 1, 2, 3 and 4
The invention provides a multi-type seed sowing device which is provided with a seed box 3, wherein the bottom of the seed box 3 is provided with a seed outlet 3a, the outer side of the bottom of the seed box 3 is connected with a sleeve 2, the sleeve 2 is provided with a seed inlet 2a, and the seed inlet 2a is connected with the seed outlet 3 a. A seed shaft 1 is arranged in the sleeve 2, a spiral blade 4 is fixed on the outer surface of the seed shaft 1, and two ends of the seed shaft 1 extend out of the sleeve 2. The sleeve 2 is provided with a group of seed discharging ports 2b, and the parts of the seed box 3 above the seed discharging ports 2b are respectively and correspondingly fixed with a shield 5, and the shield 5 surrounds the outer sides of the seed discharging shaft 1 and the blades 4 and shields the seed discharging ports 2b from above.
In this embodiment, bearings 6 are respectively mounted at two ends of the sleeve 2, and two ends of the seed shaft 1 are respectively supported by the bearings 6 disposed at two ends of the sleeve 2.
