Seedling transplanting quantitative soil-covering device and transplanting machine installing seedling transplanting quantitative soil-covering device

Abstract

The invention belongs to a seedling transplanting quantitative soil-covering device and a transplanting machine installing the seedling transplanting quantitative soil-covering device. The seedling transplanting quantitative soil-covering device comprises a lifting unit, a shovel soil transport unit, a downdip dumping unit, a detecting unit, and a control unit; the lifting unit is mounted on a transplanting frame, and the shovel soil transport unit is mounted on the lifting unit; the downdip dumping unit is installed on the transplanting frame to pour the soil of the shovel soil transport unitaround the seedling; the detecting unit is used to detect a transplanting work signal of a planter and transmit the transplanting work signal to a control unit; the control unit controls the liftingunit to drive the shovel soil transport unit to lift and descend according to the transplanting work signal, and controls the shovel soil transport unit to transport and dump the shovel soil. The device can take the soil according to the bucket, can quantitatively cover the seedlings with the soil, and uses the chain transmission as a carrier to dump the shovel soil to a required ridge height, when non soil-covering operation is carried out, the soil-covering device is lifted, and the operations such as turning and over-turning of the transplanting machine cannot be affected. The soil-coveringdevice can be used in the field of mechanized transplanting of seedlings.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a seedling transplanting quantitative soil covering device and a transplanting machine equipped with the device. Background technique [0002] Vegetable cultivation mainly adopts the method of raising seedlings and transplanting, which is convenient for fine management of seedlings. Artificial protection facilities can also be used to control the environmental conditions of seedling growth and development, which is conducive to improving the seedling rate and early sowing and harvesting periods, and it is not conducive to Cultivation and production are carried out during the growing season of vegetables. [0003] For vegetable seedlings, regardless of whether they are planted in trenches or in holes, it is necessary to cover the planted seedlings with soil to effectively conserve moisture and protect the exposed root systems of the seedlings. A film-hole soil-covering devic...

AI Technical Summary

Problems solved by technology

A film-hole soil-covering device, application number: 201220331907.2, uses a soil-taking mechanism, a soil-covering roller, a rotary tiller, and a soil-covering guide cover to achieve side-side soil-covering and soil-covering, but the soil is thrown out at a high speed and some fragile seedlings , the spilled soil particles collide with the seedlings, which will cause damage to the seedlings. In addition, the amount of soil thrown by this high-speed rotary tillage is not easy to control, which will cause uneven soil covering

A uniform soil covering device with adjustable covering soil width on the film, application number: 201611103704.7, uses a soil fetching shovel to fetch soil on one side of the rolling wheel, and the soil funnel picks up soil on the other side of the rolling wheel and covers the soil evenly, effectively Solve the problem of large fluctuations in the width of the covering soil, but use the soil shovel to fetch the soil, and the height of the soil is limited, otherwise the soil picked up by the soil shovel is easy to leak

For the effective planting area for transplanting seedlings, none of the existing technologies can cover soil in a targeted manner
