Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garden greening laying, in particular to a garden greening turf laying construction device. BACKGROUND

[0002] In the garden greening project, turf laying is a key process for improving the landscape effect.

[0003] At present, the existing turf laying method mainly relies on manual or semi-automatic equipment, and thus has the following technical defects: in the prior art, the processes of turf roll release, guided conveying, pressing and fixing, etc. need to be completed by independent equipment in steps, or rely on manual assistance for connection, which leads to the breakage of the construction process and low equipment integration. Although some semi-automatic equipment sets the laying roller and the compaction mechanism, the power transmission is mainly by chain or belt transmission, which has the problems of slipping and transmission delay, leading to the mismatch between the release speed of the laying roller and the advancing speed of the compaction mechanism, and the turf is prone to stretch and deform or stack. In addition, the width of the pressing plate of the existing equipment is mostly a fixed structure, which is difficult to shape and guide according to the width of the turf roll, so the edges of the turf are prone to "wavy" lifting, which needs manual subsequent trimming, increasing the construction cost. Furthermore, the existing device usually only sets one compaction process, and the compaction pressure is not adjustable. For the scene where the soil texture is hard or the turf root is thick, local virtual connection is easy to occur, affecting the survival rate. SUMMARY
