An adjustable coating device

Abstract

An adjustable mulching device comprises a transverse width adjusting mechanism, a vertical height adjusting mechanism, an angle adjusting mechanism, and a mulch mounting mechanism. The transverse width adjusting mechanism comprises a handle, a connecting sleeve, a support plate, a width adjusting rod, adjusting sleeves, and adjusting arms. The vertical height adjusting mechanism comprises height adjusting rods, fixing blocks, and fasteners. The angle adjusting mechanism comprises angle adjusting rods, angle adjusting nuts, and the fixing blocks. The mulch mounting mechanism comprises wheel shafts and mulch mounting wheels. The adjusting arms of the transverse width adjusting mechanism are fixedly connected with the angle adjusting nuts of the angle adjusting mechanism. The angle adjusting rods of the angle adjusting mechanism are fixedly connected with the fixing blocks. The angle adjusting nuts are connected with the angle adjusting rods in a threaded manner. The wheel shafts of the mulch mounting mechanism are connected with the height adjusting rods of the vertical height adjusting mechanism. The adjustable mulching device allows adjustment of mulch laying height, angle, width and mulch tension, mulching quality is well improved, conditions are provided for subsequent seeding, and application range of the adjustable mulching device is greatly widened.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an adjustable film covering device that can be used alone for laying plastic film or on a combined operation seeder for film covering and sowing. Background technique [0002] At present, film-covered planting is a major feature of agricultural production in my country. Due to its effect on increasing soil temperature, preserving moisture and making full use of deep soil water, it can effectively promote crop growth and save farmland water. It has been widely promoted in most parts of the country. , due to drought and water shortage areas, film mulching has become an important technology for drought resistance, water saving, and high crop yield. At present, the plastic film covering device is still in a relatively weak link in the design and research of equipment. The structure of the laying device is relatively simple, the quality of the film laying is relatively random, and...

Problems solved by technology

At present, the plastic film covering device is still in a relatively weak link in the design and research of equipment. The structure of the laying device is relatively simple, the quality of the film laying is relatively random, and it is greatly affected by the quality of the film and the surface conditions. The quality cannot be quantitatively controlled, which will have more impact on subsequent machine tool operations and crop growth
