Embodiment Construction

[0024] Attached below figure 1 to attach Figure 12 The present invention is described further:

[0025] A high-efficiency pocket hole wheel type wheat precision metering device, characterized in that: the inner surface of the seed metering device shell a1 is opposite to the hole opening on the working surface of the seed metering wheel by stretching and cutting a semi-circular cut groove , to ensure that the longest seed avoids being too long and damaged when entering the seed protection area, and at the same time, it is ensured that two small grains of wheat will not be filled in one socket at the same time, and the agronomic requirements of single-seed sowing are guaranteed. The thin iron wire 6 is wound in the groove of the seed metering wheel and fixed on the seed meter casing a1 by nuts and bolts, and the seed meter casing a1 and the seed meter casing b2 are connected to each other by bolts. Stretching and cutting a groove on the working surface of the seeding wheel 3 ...

Abstract

The invention discloses a nest-hole wheel type precise wheat seed metering device capable of realizing high-efficiency seed clearing. The nest-hole wheel type precise wheat seed metering device mainlycomprises a seed metering device shell a, a seed metering device shell b, a seed metering wheel, a bearing, a seed clearing brush, a thin iron wire, a tie rod and a seed guiding spring. The nest-holewheel type precise wheat seed metering device of the invention is characterized in that the working surface of the seed metering wheel is stretched and cut to form a groove for assembling and installing of the thin iron wire so as to ensure that seeds in a nest hole are forced to withdraw from the nest hole under the action of the thin iron wire when reaching a seed metering area; thus, wheat seeds are prevented from the situation that the wheat seeds are stuck in the nest hole and cannot be discharged, seeding distance can be effectively controlled, precise sowing of wheat seeds is easy to realize, seeds are effectively saved, and sowing efficiency and sowing quality are improved.

Description

technical field [0001] The invention relates to a seed metering device, in particular to a novel wheat precision seed metering device, which belongs to the field of agricultural machinery. Background technique [0002] China is a large agricultural production country, and wheat is one of the important food crops in our country. The output of wheat is becoming more and more important to the status of food security in our country. It is of great significance to increase the output of wheat. The quality of sowing of crops directly affects the growth and development of crops in the future. Therefore The sowing quality of wheat is particularly important for increasing yield. [0003] The seed metering device is the core component of the seeder. The performance of the seed metering device directly affects the stability of the seeding rate, the uniformity of sowing, and the emergence rate of seeds. [0004] The existing hole wheel type seed metering device mainly has serious missi...
