Description

Suspension type turf transplanter

Technical Field

The invention relates to the field of turf transplantation and greening, in particular to a suspension type turf transplanter.

Background

For the sections where the vegetation is difficult to grow, in order to protect the vegetation, a method of sectional construction and vegetation transplanting is adopted during construction, namely, each section of railway is divided into a plurality of construction sections, soil taking pits and roadbed basal turf of the section are shoveled down and then are timely transplanted to the roadbed side slope and the soil taking field ground surface which are constructed in advance, so that the loss of the ground surface vegetation is reduced to the minimum degree.

The grass transplanting is one of means with the fastest effect and the lowest cost, the existing small transplanting apparatus for the grass transplanting has higher requirements on the environmental temperature and the transplanting time, if the grass emergence time is too long, the early grass is easy to dry, the survival rate is reduced, the grass needed by greening engineering is generally large in quantity and urgent in time, more personnel are needed to prepare the grass to supply the grass, the existing grass transplanting apparatus is mostly large-scale whole machine equipment with a power mechanism or handheld equipment with the power mechanism, the occupied space is large, and the manufacturing cost and the maintenance cost are high; the cutter is mostly flat blade specification, in the cutting process, the middle part of the cutter is stressed more than the two sides, so the phenomenon that the turf on the two sides is still connected with the ground after the turf on the middle part is shoveled exists, the cutting effect is not ideal, during the weeding process, the turf floats in a small range and is not attached to the cutter, so that the cutting and rolling are difficult, the growth of the turf after transplantation is even influenced, secondly, after the grass is cut, the grass quilt needs to be rolled manually, the operation difficulty is increased, the existing cutters are mostly connected with the equipment through bolts, during the operation of the equipment, the equipment can generate vibration, the vibration can cause the looseness of the bolt connection part, the looseness of the connection part can reduce the use safety of the equipment, and the bolt is connected by adopting a bolt connection mode, the bolt is easy to slip after being used for a long time, the bolt needs to be continuously replaced, the cost is increased, and the working efficiency is influenced.
