Abstract

A high-filling internal-filling type soybean seed-metering disc belongs to agricultural machinery: the inner part of the outer plate with the circumferentially and uniformly distributed seed filling cells consists of a cylindrical surface and a conical surface, the bottom of the outer plate is a plate surface, a shaft hole and a key groove are arranged in the middle of the plate surface, the seed filling cell rotating shaft inclines by 30 degrees in the radius direction, the seed filling cell is provided with a seed filling chamfer, the traditional cell wheel-row seed plate is split into the cylindrical surface, the conical surface and the plate surface, the circumferentially and uniformly distributed seed filling cells are arranged on the cylindrical surface, the conical surface and the cylindrical surface form a certain angle, seeds can slide into the cells more easily, the shaft hole and the key groove of the plate surface can be matched with a seed discharging shaft, meanwhile, the seed filling cell rotating shaft inclines by 30 degrees in the radius direction, the seeds can be stably and hardly fall off in a molded hole in the rotation process of the seed discharging plate, the operation quality is improved, and meanwhile, the seed discharging plate.

Description

High-filling internal-filling type soybean seed-metering disc

Technical Field

The invention belongs to agricultural machinery, and mainly relates to a high-filling internal filling type soybean seed metering disc.

Background

The soybean is one of the main grain crops in China and is a typical crop suitable for precision sowing, and the traditional sowing method is drill sowing or hole sowing. With the progress of agricultural technology and the improvement of breeding technology, the traditional sowing method has the problems of seed waste, high thinning labor cost and the like. At present, the internal filling type seed sowing device used by the soybean sowing machine has the problems of seed leakage and the like caused by the fact that the seed sowing plate is not easy to fill seeds and the seeds in the cells are easy to fall off along with the rotation of the seed sowing plate in the actual operation, so that the seed sowing plate has the advantages of easy seed filling, difficult seed falling of the seeds in the cells and the like, improves the sowing efficiency, realizes the yield and income increase of crops, and has important significance for the development of agricultural modernization in China.

Disclosure of Invention

The invention aims to solve the problems in the prior art, and researches and designs a high-filling internal filling type soybean seed metering disc, compared with the traditional seed metering device, the seed can easily fall into a pocket because the inner surface of the seed metering disc is a conical surface, and a seed filling pocket rotating shaft inclines by 30 degrees in the radius direction, so that the seed can be stably and difficultly fall off in the pocket in the rotation process of the seed metering disc, and the working efficiency is improved.

The purpose of the invention is realized as follows: the inner part of the outer disc with the circumferentially and uniformly distributed seed filling cells sequentially consists of a disc surface, a conical surface and a cylindrical surface from inside to outside, the middle of the disc surface is provided with a shaft hole and a key groove, the rotating shaft of the seed filling cells inclines 30 degrees in the radius direction, the seed filling cells are provided with seed filling chamfers, and accordingly the high-filling inner filling type soybean seed metering disc is formed.

The seed discharging disc is divided into a cylindrical surface, a conical surface and a disc surface by the traditional pocket wheel seed discharging disc, seed filling pockets are uniformly distributed on the cylindrical surface in the circumferential direction, a certain angle is formed between the conical surface and the surface of the cylindrical surface, seeds can slide into the pockets more easily, a shaft hole and a key groove of the disc surface can be matched with a seed discharging shaft, meanwhile, a seed filling pocket rotating shaft inclines for 30 degrees in the radius direction, the seeds can be stably and difficultly fall off in a shaped hole in the rotating process of the seed discharging disc, and the operation quality is improved.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the accompanying drawings:

fill formula soybean seed metering dish in high filling, its characterized in that: the inside outer dish 7 that kind pocket 4 was filled to circumference equipartition is by interior to outer disc 5, conical surface 1 and face of cylinder 2 constitution in proper order, be equipped with shaft hole 6 and keyway 3 in the middle of disc 5, it inclines 30 on the direction of radius to fill kind pocket 4 revolving axle, it is equipped with and fills kind chamfer 8 to fill kind pocket 4.

During operation, the seed discharging disc is fixedly arranged on the seed discharging shaft through the shaft hole 6 and the key groove 3, the high-filling internal filling type soybean seed discharging disc 7 rotates along with the seed discharging shaft, seeds enter the seed discharging disc 7 from the seed box, the seeds slide down to the cylindrical surface 2 from the disc surface 5 along the conical surface 1 due to the existence of the inclined angle of the conical surface 1, the seeds smoothly fall into the seed filling cells 4 due to the existence of the seed filling chamfers 8, and the rotary shaft of the seed filling cells 4 inclines 30 degrees in the radius direction, so that the seeds can be stably arranged in the holes and rotate along with the seed discharging disc to complete seed discharging.

Claims

1. Fill formula soybean seed metering dish in high filling, its characterized in that: the outer dish (7) of kind nest eye (4) is filled to circumference equipartition is inside by interior outside to constitute by disc face (5), conical surface (1) and face of cylinder (2) in proper order, be equipped with shaft hole (6) and keyway (3) in the middle of disc face (5), it inclines 30 on the radius direction to fill kind nest eye (4) revolving axle, it is equipped with and fills kind chamfer (8) to fill kind nest eye (4).
