A kind of strong discharge and strong start corn direct insertion hole seeder

Abstract

The invention relates to the technical field of an agricultural cultivation cavitation device, in particular to a forcible-arrangement forcible-starting corn straight-inserting hole-sowing machine. The forcible-arrangement forcible-starting corn straight-inserting hole-sowing machine comprises a machine frame and is characterized in that the front part of the lower end of the outer part of the machine frame is connected with a front wheel shaft through a bearing with a base; a differential is arranged at the middle position of the front wheel shaft; a power output shaft of a motor is connectedwith the differential through a chain wheel mechanism; an electromagnetic clutch is arranged on the upper side of the middle end of the internal part of the machine frame; the electromagnetic clutchis connected with the power output shaft of the motor through the chain wheel mechanism; the electromagnetic clutch is connected with power input shafts of a horizontal speed compensation mechanism, aconjugated cam mechanism and a seed arrangement device through the chain wheel mechanism; a straight-inserting seed arrangement device is arranged below the horizontal speed compensation mechanism; the back end of the outer part of the machine frame is vertically connected with a steering shaft through the bearing with the base; the lower end of the steering shaft is connected with back wheels through two connecting rods; and the middle part of the connecting rods is connected with the upper end of the steering shaft through an electric push-pull rod. The forcible-arrangement forcible-starting corn straight-inserting hole-sowing machine effectively relieves the problems that under-membrane sowing and sowing qualification rate are greatly influenced by the ground.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation hole forming devices, in particular to a strong row and strong start corn direct insertion hole seeder. Background technique [0002] The geographical environment in Gansu is harsh, and there have been nine droughts in ten years. Plastic film mulching technology can maximize the effect of increasing temperature and preserving moisture. At present, most film-covered seeders in China use the mode of sowing first and then spreading film. Before emergence, it is necessary to manually or mechanically break the film to release the seedlings, which increases the operation process and labor intensity. The perforated seeding technology on the film is perforated and sown on the film, which saves the process of putting seedlings. [0003] In 1993, Chen Xiaoguang first proposed and in-line seeding principle. Since then, a lot of research has been done on in-line sowing in China. In 2001, L...

Problems solved by technology

[0004] "Autumn mulching" and "Dingling mulching" in Northwest China have obvious advantages over traditional mulching. "Autumn mulching" is to keep the rainfall in March (July, August, and September) in autumn and plant corn in April of the next year. It is used for germination and rooting; "top mulch" is to avoid the loss of moisture on the surface during the process of "freezing day and night", but it is more difficult to sow

For the two mulching methods, Gansu still generally adopts manual or simple machinery, which has high labor intensity and low sowing qualified rate

Almost all domestically developed and mature film seeders are roller-type seeders. When sowing shallow crops, the trochoidal movement track of the hole forming device has little effect on the film. When planting deep crops, it is easy to cause film picking and scraping. and other problems, the windy northwest will aggravate the cracking of membrane holes; at the same time, the soil around the seeds is disturbed greatly, resulting in a longer seed germination cycle

The in-line sowing technology uses a puncher to punch holes in the soil covered by plastic film, and only cuts the film at the hole position, which is beneficial to moisture conservation and drought resistance. However, the sowing performance of passive in-line hole sowing in the existing technology is greatly affected by the ground level.
