Background
The dry direct seeding of rice is divided into two kinds of seeding modes of drill seeding and hill-drop seeding, wherein the rice drill seeding is a traditional operation mode, and because the seeding is carried out by adopting an outer sheave seed metering device, the seeding uniformity is poor, the precision is not high, the seed damage rate is higher, the seeding quantity is large, and the phenomenon of broken ridges occurs in the time. In recent years, with the improvement of the technological level of agricultural technology, the net photosynthetic rate of the leaves in the booting stage and the middle and later stage of grouting of the rice precision hole sowing is obviously higher than that of the rice manually sown, so that the fact that the precision hole sowing has higher photosynthetic capacity is proved. Based on the advantages of the precision rice hole sowing operation, the operation machines have been developed, but due to the defects of structural design, the existing rice hole sowing machines cannot realize zero-speed seed throwing, the precision of the hole sowing seed spacing is difficult to guarantee during operation, the sowing uniformity is poor, and the growth of rice crops is influenced. Therefore, the development of a rice dry direct seeding operation mechanism which can realize hole seeding and zero-speed seed throwing is imperative.
Disclosure of Invention
The invention aims to solve the problems in the prior art, and researches and designs a zero-speed hole sowing wheel type rice dry direct sowing mechanism with a novel structure by combining the actual requirements of rice hole sowing dry direct sowing operation, so as to achieve the purpose of ensuring and improving the precision and the uniformity of hole sowing spacing.
The purpose of the invention is realized as follows: a plurality of cylinder chutes are uniformly distributed and arranged on the circumferential edge part of the seed discharging wheel along the circumferential radial direction, an annular baffle plate is fixedly arranged on the circumferential edge part of the seed discharging wheel to cover and block the cylinder chutes to form a hole, a closed cover plate can be relatively rotatably arranged on the central part of the seed discharging wheel and is positioned at the inner side part of the annular baffle plate, a seed chamber is formed between the closed cover plate and the seed discharging wheel, a pin shaft is rotatably arranged on the closed cover plate, a column frame is arranged on the pin shaft and at the inner part of the seed chamber, a plurality of seed filling cylindrical spoons are sequentially and uniformly distributed and fixedly arranged on the outer end part of the column frame with the same turning radius, the distance size of an arc line between the adjacent seed filling cylindrical spoons is the same as the distance size of an inner arc line between the adjacent cylinder chutes on the seed discharging wheel, an arc seed cleaning and protecting plate is fixedly arranged on the inner wall surface of the closed cover plate positioned in the seed chamber, and the arc seed, the inner end part of the cylinder chute in the seed chamber is sequentially provided with a seed blocking brush and a double-petal opening-closing type elastic seed protection assembly from inside to outside, the double-petal opening-closing type elastic seed protection assembly can slide and open in the cylinder chute along the radial direction, and a seed conveying hole is formed in a sealing cover plate, so that the zero-speed hole sowing wheel type dry direct rice seeding mechanism is formed.
The dry direct seeding zero-speed hole sowing seed throwing device realizes the dry direct seeding zero-speed hole sowing seed throwing of the rice when the device is used, and has the characteristics of novel and reasonable structure, high precision of hole sowing distance, good uniformity and reliable use.

Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A zero-speed hole sowing wheel type rice dry direct sowing mechanism is characterized in that a plurality of cylinder chutes 2 are uniformly distributed and arranged on the circumferential edge part of a seed sowing wheel 1 along the circumferential radial direction, an annular baffle 3 is fixedly arranged on the circumferential edge part of the seed sowing wheel 1 to cover and block the cylinder chutes 2 to form a hole, a closed cover plate 4 is relatively rotatably arranged on the central part of the seed sowing wheel 1 and is positioned at the inner side part of the annular baffle 3, a seed chamber 10 is formed between the closed cover plate 4 and the seed sowing wheel 1, a pin shaft 8 is rotatably arranged on the closed cover plate 4, a column frame 7 is arranged on the pin shaft 8 and is positioned in the seed chamber 10, a plurality of seed filling cylinder spoons 6 are sequentially and uniformly distributed and fixedly arranged on the outer end part of the column frame 7 with the same turning radius, the distance size of an arc line between adjacent seed filling cylinder spoons 6 is the same as the distance size of an inner arc line between adjacent cylinder chutes 2 on the seed sowing wheel 1, and a circular arc seed cleaning and protecting plate 5 is, the circular arc seed cleaning and protecting plate 5 is matched with a plurality of seed filling cylindrical spoons 6 in a discontinuous seed cleaning and protecting operation in sequence, a hair brush 11 and a double-flap opening-closing type elastic seed protecting assembly 9 are sequentially assembled on the inner end part of the cylinder chute 2 positioned in the seed chamber 10 from inside to outside, the double-flap opening-closing type elastic seed protecting assembly 9 can slide and open in the cylinder chute 2 along the radial direction, and the seed conveying hole 12 is formed in the closed cover plate 4.
