An electric small-diameter vegetable hole seeder

Abstract

The invention discloses an electric small-grain-size vegetable hill-drop planter. A rear wheel is mounted on the rear end of a frame by use of a rear shaft while a front wheel is mounted on the front end of the frame by use of a front shaft; a main traveling chain wheel is fixedly mounted on one end of the rear shaft and a slave traveling chain wheel is fixedly mounted on one end of the front shaft; the main traveling chain wheel is connected with the slave traveling chain wheel by use of a chain; a driving chain wheel is fixedly mounted on the other end of the rear shaft; a driven chain wheel and a main sowing chain wheel are coaxially fixedly mounted on the frame; a sowing wheel shaft is mounted on the frame by use of a bearing block and is parallel to the rear shaft; a slave sowing chain wheel is mounted on one end of the sowing wheel shaft; the driving chain wheel is connected with the driven chain wheel by use of a chain; a main sowing chain wheel is connected with the slave sowing chain wheel by use of a chain; the front and back ends of a seed metering device are mounted on the frame by use of a front support shaft and a rear support shaft; a seeder metering shaft is mounted on the seed metering device; a first driving wheel is mounted on the sowing wheel shaft and is coaxial with the sowing chain wheels; a second driving wheel is mounted on the seed metering shaft; the first driving wheel is engaged with the second driving wheel; an opener is mounted on the lower end of the seed metering device.

Description

technical field [0001] The invention belongs to an agricultural machine, and more specifically relates to an electric small-diameter vegetable hole seeder, which is suitable for use in steel-frame greenhouses and other facilities. Background technique [0002] In recent years, in order to enrich the supply of vegetable baskets for urban residents, facilities such as steel-frame greenhouses have been widely used to grow fast lettuce in order to meet the market's vegetable demand. The space in the steel-frame greenhouse is limited, and it is difficult for traditional large-scale tractors and other agricultural machinery to operate in the greenhouse. In addition, after the greenhouse is covered with film, it is difficult to remove the exhaust gas emitted by the machinery and equipment, which is likely to cause secondary pollution and affect the quality of vegetables. However, if all manual work is adopted, the processes such as ditching, sowing, and soil covering are time-consu...

Problems solved by technology

The space in the steel-frame greenhouse is limited, and it is difficult for traditional large-scale tractors and other agricultural machinery to operate in the greenhouse. In addition, after the greenhouse is covered with film, it is difficult to remove the exhaust gas emitted by the machinery and equipment, which is likely to cause secondary pollution and affect the quality of vegetables.

However, if all manual work is adopted, the processes such as ditching, sowing, and soil covering are time-consuming, labor-intensive, and the sowing efficiency is low. After the seedlings emerge in the later stage, a large amount of thinning costs are required, which not only wastes the seeds, but also greatly increases the cost of planting. Labor cost
