Technical Field
The invention belongs to agricultural machinery, and mainly relates to a zero-speed hole sowing wheel type direct seeding mechanism for paddy rice dry direct seeding operation.
Background
The rice dry direct seeding is divided into two seeding modes, namely drill seeding and hill seeding, wherein the rice drill seeding is a traditional operation mode, and because the rice drill seeding adopts an outer grooved wheel seeding device for seeding, the seeding uniformity is poor, the precision is low, the seed damaging rate is higher, the seeding quantity is large, and the phenomenon of broken ridges occurs. In recent years, with the improvement of agricultural technology, as the net photosynthetic rate of the leaves of the precise hill sowing of the rice in the booting period and the middle and later period of grouting is obviously higher than that of the manual sowing of the rice, the precise sowing of the rice leaves has higher photosynthetic capacity, and the important reason is that the precise hill sowing improves the field permeability, photosynthetic area and group photosynthetic production capacity, and increases the rice yield while improving the rice quality. Based on the advantage of the precise hill-drop operation of rice, the operation machine has been developed, but due to the defect of structural design, the existing rice hill-drop machine can not realize zero-speed seed feeding, and the precision of the hill-drop seed-grain spacing is difficult to ensure during operation, so that the sowing uniformity is poor, and the growth of rice crops is influenced. Therefore, research and development of a paddy rice dry direct seeding operation mechanism capable of realizing hill seeding and zero-speed seeding is imperative.

The invention aims to solve the problems in the prior art, combines the actual requirements of the hill seeding and dry direct seeding operation of rice, researches and designs a zero-speed hill seeding wheel type rice dry direct seeding mechanism with a novel structure, and achieves the aims of ensuring and improving the precision and uniformity of the hill seeding and the seeding space.
The aim of the invention is realized in the following way: a plurality of cylinder sliding grooves are uniformly distributed on the circumferential edge part of the seed metering wheel along the circumferential radial direction, an annular baffle plate is fixedly arranged on the circumferential edge part of the seed metering wheel to cover the sealing and blocking holes, a sealing cover plate is rotatably assembled on the central part of the seed metering wheel and positioned at the inner side part of the annular baffle plate, a seed cavity is formed between the sealing cover plate and the seed metering wheel, a pin shaft is rotatably arranged on the sealing cover plate, a column frame is arranged on the pin shaft and positioned at the inner side part of the seed cavity, a plurality of seed filling cylindrical spoons are uniformly distributed and fixedly arranged on the outer end part of the same rotation radius of the column frame in sequence, the distance between circular arc lines between adjacent seed filling cylindrical spoons is the same as the distance between circular arc lines between adjacent cylinder sliding grooves on the seed metering wheel, the circular arc seed cleaning and protecting plates are fixedly assembled on the inner wall surface of the sealing cover plate positioned in the seed cavity in sequence and are in intermittent seed cleaning and protecting operation, the inner end part of the cylinder sliding spoons positioned in the seed cavity are sequentially assembled with a seed blocking elastic seed brush and a double-flap type seed protecting assembly from inside to outside, and the double-flap type elastic seed sealing and protecting assembly can be opened in the direction of the same as the seed sealing and blocking mechanism along the radial direction.
The invention realizes zero-speed hill sowing and seed throwing of rice dry direct sowing when in use, and has the characteristics of novel and reasonable structure, high precision of hill sowing intervals, good uniformity and reliable use.
