Ridge pressing and membrane covering device

Abstract

The invention discloses a ridge pressing and membrane covering device. The ridge pressing and membrane covering device comprises a machine frame, a mulching membrane laying device, first-stage soil covering devices and second-stage soil covering devices, wherein the mulching membrane laying device, the first-stage soil covering devices and the second-stage soil covering devices are installed on the machine frame. The machine frame walks along a ridge under the traction of a traction device. The mulching membrane laying device is used for flat laying a mulching membrane on the ground under themachine frame in the walking process of the machine frame. The two first-stage soil covering devices are installed on the two sides of the machine frame and used for covering the two sides of the laidmulching membrane with soil. The two second-stage soil covering devices are installed on the two sides of the machine frame and used for covering the mulching membrane with the soil piled by the first-stage soil covering devices. Each first-stage soil covering device comprises soil covering blades which are installed on the machine frame through fixing rods. Each second-stage soil covering devicecomprises a soil conveying box, a spiral conveying rod and a driving device. The spiral conveying rod is vertically installed in the soil conveying box and driven by the driving device to rotate. Theridge pressing and membrane covering efficiency is high, the mulching film covering integrity and tightness are ensured, and meanwhile operation time is saved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to an agricultural machinery, in particular to a ridge pressing and film covering device. Background technique [0002] The use of plastic film is beneficial to increase soil temperature, maintain soil moisture, prevent external microorganisms from causing diseases, etc., and then promote plant growth. In the process of using the existing ridge film covering device, the film pressing roller is used to press the film on the soil surface, and then the nearby soil is covered on both sides of the film by the soil covering blades thereafter. [0003] However, after practical use, it has been found that the soil-covering blades are set closer, sometimes scraping the sides of the plastic film, causing the plastic film to turn up or be damaged, and when the soil-covering blades are set farther away, the soil covered on both sides of the plastic film is insufficient. The impact of the pl...

[0003] However, after practical use, it has been found that the soil-covering blades are set closer, sometimes scraping the sides of the plastic film, causing the plastic film to turn up or be damaged, and when the soil-covering blades are set farther away, the soil covered on both sides of the plastic film is insufficient. The impact of the plastic film will lead to dislocation and upturning of the film, and it has to be covered again, or it must be compacted manually by following the machine to ensure the normal use of the film. This wastes time and manpower and greatly reduces work efficiency. Moreover, when the plastic film is covering, if it is necessary to cover the uneven surface of the ridge side of the plastic film, the covering process of the plastic film will lead to inaccurate coverage of the plastic film, air leakage, or overlap or bending when the plastic film is covered. , resulting in re-overwriting, very troublesome
