Seed metering device capable of conveying seeds forward

Abstract

The invention discloses a seed metering device capable of conveying seeds forward. The seed metering device capable of conveying seeds forward comprises a gearbox, a housing, a conveyer belt, a driving wheel, a driven wheel, a seed separating plate, a bucket wheel, and a transparent hood; the housing is connected with a gearbox housing so as to form a cavity used for accommodating the conveyer belt; a plurality of dialing pieces are uniformly distributed on the external wall of the conveyer belt; the dialing pieces and the conveyer belts are designed to be a one-piece structure; the conveyer belt is provided with holes among the dialing pieces; the driving wheel and the driven wheel are arranged on the internal sides of the two ends of the conveyer belt; convex teeth matching the holes onthe conveyer belt are arranged are the external wall of the driving wheel so as to prevent falling of the conveyer belt off from the driving wheel in transmission process; a protective cover is arranged on the external part of the housing; the external side of the driving wheel is provided with the seed separating plate, the bucket wheel, and the transparent hood successively. According to the seed metering device, the soft conveyer belt is used for replacing a seed guide disc, so that seed broken rate is reduced; the conveyer belt is used for conveying seeds, seeds are conveyed to positions about 15cm away from trench digging points, seed falling points are accurate, depth is consistent, and the optimal seedling emergence states are achieved.

Description

technical field [0001] The invention relates to a seed metering device, in particular to a seed metering device for forward feeding, and belongs to the technical field of seed metering devices for seeders. Background technique [0002] At present, the known seed metering device, such as the Chinese utility model patent, CN202603188U discloses a scoop wheel seed metering device with a multi-gear plant distance regulator, including: a housing, and the housing is connected to the seed metering device housing , the driving gear shaft and the driven gear shaft pass through the housing and the seed meter housing, the shaft end of the driving gear shaft is equipped with a driving sprocket, and the shaft end of the driven gear shaft is equipped with a spoon The driving gear is installed on the driving gear shaft, and the passive gear is installed on the driven gear shaft; the shift handle is connected with the driving gear and the intermediate gear through a bracket.

AI Technical Summary

Problems solved by technology

The disadvantages are: 1. The installation position of the seed meter is more than 10 cm away from the ground, and the distance between the seed drop point and the ditch tip is about 30 cm. Different depths on the ditch or drying seeds, resulting in poor germination effect

2. The installation position of the seed meter is too low, which is not conducive to observing the condition of the seed meter when sowing, and is not conducive to the shifting operation of the gearbox of the seed meter

3. The installation position of the seed meter is too close to the ground, so that the straw and weeds in the land are congested, which reduces the farmers' sowing benefits. Therefore, most farmers burn straw and weeds in a large area, which not only pollutes the air, but also Crops will also be affected

4. The installation position of the seed meter is too close to the ground, and there are too many impurities on the ground when the machine sows, which greatly increases the probability of damage to the seed meter, which directly affects the efficiency of farmers' sowing and causes losses

The present invention has the disadvantages of cumbersome and complex structure, unreasonable design, low work efficiency, and difficult maintenance when problems occur.
