Machine for furrowing and spreading mulch film and pruning root for shelter belt in farmland

Abstract

The invention discloses a root-cutting and trench-digging film-spreading machine for farmland protective forest belts, and the aim is to cut roots and dig narrow trenches by echelons and spread plastic films automatically and perpendicularly. The invention has the advantages of high working efficiency and easy and simple operation. The invention comprises a hanger bracket, a framework and a left and a right two depth limiting wheels which can be regulated in height. An obstacle-breaking and roots-cutting shovel is perpendicularly mounted below the front portion of the framework, a front and a rear two groups of trench-digging and roots-cutting components are respectively arranged at the position which is backwards arranged below the framework and in the same longitudinal plane with the obstacle-breaking and roots-cutting shovel, and the obstacle-breaking and roots-cutting shovel and the two groups of trench-digging roots-cutting components backwardly form echelon deepening arrangements along the perpendicular direction, and the echelon deepening arrangements are connected with the trench-digging and roots-cutting components and are provided with film-spreading devices. The invention is applicable to root-cutting and trench-digging and perpendicular film-spreading for farmland protective forest belts, root-cutting and film-spreading among lines of fruit trees, and root-cutting and film-spreading, and film-spreading and water resistance for forest belts on two sides of roads.

Description

technical field [0001] The invention belongs to a ditching machine, in particular to a root-cutting, ditching and film-laying machine for farmland shelterbelt belts, which can cut tree roots step by step to open narrow ditches and simultaneously lay plastic films vertically. Background technique [0002] In recent years, some new trenching machines have been applied, and many excellent technical solutions have been designed technically for the performance of trenching machines. For example, Chinese Patent Publication No. CN2931583Y, published on August 8, 2007, the name of the invention is 'a trench digging machine', and the application discloses a trench digging machine. The trencher includes a main engine, a main frame, an oil cylinder and a plowshare. There are two plowshares. The depth of the plow head is deep, and the adjustable soil divider is installed on the two plowshares. The probe is fixed on the bottom surface of the main frame between the main frame and the fro...

Problems solved by technology

However, there are still shortcomings: the width of the trench is large, and a large amount of soil is turned to the surface, which will damage the soil vegetation, easily cause water and soil erosion, the roots of the tree will not be cut neatly, and the plastic film cannot be automatically placed vertically in the trench, and the root blocking effect is poor.
