Soil feeding and covering and compacting device after on-film transplanting

Abstract

The invention discloses a soil feeding and covering and compacting device after on-film transplanting, belonging to agricultural machinery. The soil feeding and covering and compacting device comprises an intermittent soil feeding packing auger, a covering device and a notch type compacting wheel, wherein power is transmitted to two packing augers through intermittent bevel gear drive, the soil feeding packing auger is arranged outside a cylinder body, the packing auger extends out of the cylinder at the soil taking end and is provided with a limit wheel, soil is collected from the ground, a notch type spiral disc fixedly connected with an auger shaft is arranged on the soil discharging end of the cylinder body, continuous soil feeding of the auger is changed into intermittent soil discharging by means of a notch, two piles of soil are formed at two sides of the rear side of a transplanted seedling, and the other soil feeding manner is as follows: a soil box is arranged on a machine, and two piles of soil are placed on the same position by two notch type runners; the two piles of soil are pushed to the transplant seedling towards the middle and the advancing direction through the triangular covering device, a film notch is closed; the peripheral velocity and an advancing speed of the notch type compacting wheel are the same, so that the soil is compacted; and because the distance between the soil feeding and covering and compacting device and the film and the soil is short, the accumulative error is small, and the damage probability to the film is small.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a device for sending soil, supporting soil and suppressing soil after transplanting on a film. Background technique [0002] In the early 1980s, my country began to develop plastic film mulching and transplanting agronomic technology. Transplanting on film has the characteristics of increasing soil temperature, enhancing soil water retention, improving soil properties, and reducing weed damage. At present, the transplanting of vegetables, tobacco, flowers and other crops on film has shown the advantages of increasing yield and quality. [0003] After transplanting on the film, processes such as covering with soil and pressing are required, which increases the difficulty of designing the transplanting machine on the film. At present, the mechanical structure of transplanting pot seedlings on the film on the market is complicated, the cost is high, and the maintenance is difficult. The c...
