A ridge pressing device

Abstract

The invention discloses a ridge pressing and film covering device, which comprises a machine frame, a film laying device installed on the machine frame, a primary soil covering device and a secondary soil covering device, and the frame walks along the ridge under the traction of a traction device , the mulching film device is used to spread the mulch film on the bottom surface under the frame during the frame walking process, and there are two first-level soil covering devices, which are respectively installed on both sides of the frame for covering the soil on the The two sides of the plastic film have been laid, and there are two secondary soil covering devices, which are respectively installed on both sides of the frame, and are used to cover the soil piled up by the primary soil covering device on the plastic film; the primary soil covering device includes soil covering blades, The soil covering blade is installed on the frame through the fixed rod. The secondary soil covering device includes a soil conveying box, a screw conveying rod and a driving device. The spiral conveying rod is vertically installed in the soil conveying box and driven to rotate by the driving device. The invention of ridge pressing and film covering has high efficiency, which ensures the completeness and tightness of film covering and saves working time at the same time.

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
