Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural machinery technical field, concretely is a wild barley seeding machine. BACKGROUND

[0002] Wild barley (Hordeum brevisubulatum (Trin.) Link) belongs to perennial herbaceous plants of the genus Hordeum of Poaceae, as one of the salt-tolerant plants in the tribe Triticeae of Poaceae, has very close genetic relationship with barley and wheat. It has the characteristics of high yield, good palatability and high nutritional value, and is used as an advantageous germplasm resource for hybrid new varieties of crops and forage grasses. In the cultivation process of wild barley, it is necessary to explore the influence of seeding row spacing on wild barley in order to obtain the best seeding density and thus obtain the highest yield at a reasonable row spacing.

[0003] For example, the six-row wheat seeder disclosed in the Chinese patent with the authorization announcement number CN214592817U includes a walk-behind tractor, a control handle, a connecting block, a rack, a support assembly, a seeding assembly, and a seeding component. The walk-behind tractor is fixedly connected with a control handle on one side for operating the walk-behind tractor. The connecting block is fixedly connected to the upper end of the rack on one side. The rack is fixedly connected with the walk-behind tractor through the connecting block. The utility model adjusts the relative position of the furrow opener during seeding by setting an adjusting plate, a fixed pin, a connecting seat, an adjusting hole, and a connecting rod. The seeding depth is adjusted. When the fixed pin is inserted into the adjusting hole at the uppermost end of the adjusting plate, the seeding depth is the deepest. When the fixed pin is inserted into the adjusting hole at the lowermost end of the adjusting plate, the seeding depth is the shallowest. The seeding depth of the seeding machine can be adjusted according to the soil conditions of the field, and the seeding effect of wheat is better.

[0004] However, in actual application, the above-mentioned seeder cannot adjust the row spacing during seeding in actual use, so it cannot explore the influence of seeding row spacing on wild barley and cannot obtain the best seeding density.
