Sorghum precision furrow seeder

Abstract

The invention discloses a precise sorghum furrow drill which belongs to a furrow drill. The precise sorghum furrow drill structurally comprises a rack, a seed collecting box, land wheels and a traction frame, wherein a plurality of separation bin plates are arranged in the seed collecting box, the seed collecting box is divided into a plurality of seed bins, seed distributors are respectively arranged at the lower part of the seed bins, and are respectively connected with land wheel chain wheels through seed distributor chain wheels, a plurality of land wheel chain wheels are respectively arranged on a land wheel axle, two ends of the land wheel axle are respectively connected with a left land wheel and a right land wheel, a furrow opener is arranged at the lower part of each seed distributor, a press wheel is respectively arranged at the rear part of each seed distributor; each seed distributor respectively comprises a seed distributing box, a separation disc, a seed distributing rotating disc, a rotating shaft, a seeding pipe and a seed charging device. The precise sorghum furrow drill has the advantages that the sorghum seeding precision is improved, the requirement of intervals of one particle, two particles and the like can be completed, each seed distributor is singly provided with a driver, and can be randomly replaced; surface soil is pushed to two sides by the furor opener to form a ridge, and thus the salinity content on the bottom of the ridge is reduced, and the germination and the seedling emergence of seeds are facilitated.

Description

technical field [0001] The invention relates to a furrow sower, in particular to a sorghum precision furrow sower in saline-alkali land. Background technique [0002] At present, sorghum sowing is mostly carried out by general-purpose machinery, and the sorting disc adopts the method of axial cavity. Although this kind of sorting method is convenient and quick, it lacks precision, and sometimes there will be vacancies, which will affect the precision of sowing. Due to the current seeding machine is used to complete the seeding by means of fixed holes or socket wheels, although the seeding density can be increased by changing the seeding speed, the number of seeded grains cannot be changed. The seeding disc is connected to a shaft in series. It is good to replace it at any time. In addition, due to the transpiration of water in saline-alkali land, the soil surface has the characteristics of returning to salt, so the saline-alkali content of the soil surface is relatively hig...

Problems solved by technology

[0002] At present, sorghum sowing is mostly carried out by general-purpose machinery, and the sorting disc adopts the method of axial cavity. Although this kind of sorting method is convenient and fast, it lacks precision, and sometimes there will be vacancies, which will affect the precision of sowing.

Due to the current seeding machine is used to complete the seeding by means of fixed holes or socket wheels, although the seeding density can be increased by changing the seeding speed, the number of seeded grains cannot be changed. The seeding disc is connected to a shaft in series. good to replace anytime

In addition, due to the transpiration of water in saline-alkali land, the soil surface has the characteristics of returning to salt, so the saline-alkali content of the soil surface is relatively high, which reduces the emergence rate and quality of sorghum

[0003] Currently, there is no good solution
