Trailed combined working machine for ridging, furrowing, paving films and covering soil on film edges

Abstract

The invention discloses a trailed combined working machine for ridging, furrowing, paving films and covering soil on film edges. The trailed combined working machine comprises a machine frame, two ridging blades, two furrowing blades, a film unfolding roller, two soil covering plates, two film pressing wheels and a film hanging frame, wherein the two symmetrical ridging blades are arranged in the center of a middle transverse beam of the machine frame; the two furrowing blades are symmetrically arranged outside the ridging blades; the film hanging frame is arranged on a rear longitudinal beam of the machine frame; the film unfolding roller is arranged at the lower rear end of the film hanging frame; the two film pressing wheels corresponding to the furrowing blades are arranged on the rear longitudinal beam of the machine frame; and the two soil covering plates are arranged outside the two film pressing wheels respectively. The trailed combined working machine can perform a plurality of processes of ridging, furrowing, paving the films and covering the soil on the film edges once by taking animal power and man power as trailing power. The ridging blades can be adjusted by moving leftwards, rightwards, upwards or downwards according to the sizes and heights of ridges; and the furrowing blades can be adjusted by rotating leftwards, rightwards, upwards or downwards according to the amount of the soil to be covered on the film edges. The trailed combined working machine is simple in structure, light in weight and convenient to adjust and can be moved flexibly.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a traction type ridge ditching, film laying, and film edge-covering combined working machine. Background technique [0002] The mulching method has the functions of maintaining moisture, raising moisture and increasing ground temperature. It is an effective way to increase grain yield in arid areas. At present, domestic agricultural machinery researchers have designed various forms of ridge and film laying machines. From performance, characteristics, Reliability and other aspects have their own characteristics. The disadvantage is that the existing implements can only be used with four-wheel tractors or tillers. my country's national conditions are that there are many people and less land, and the arable land is small and scattered. The existing machines and tools cannot operate in the mountains and sloping fields, and cannot be used in conjunction with human and animal powe...

Problems solved by technology

[0002] The mulch film planting method has the functions of preserving moisture, increasing moisture, and increasing ground temperature. It is an effective way to increase food production in arid areas. At present, domestic agricultural machinery researchers have designed various forms of ridge filming machines. From the performance, characteristics, Reliability and other aspects have their own characteristics. The disadvantage is that the existing implements can only be used with four-wheel tractors or tillers.

my country's national conditions are that there are many people and little land, and the cultivated land is small and scattered. Existing machinery and tools cannot work in mountainous and sloping fields, and cannot be used with human and animal power, or the machines and tools used with human and animal power have single functions and membrane edges. The soil is not tightly covered and the plastic film is easy to be blown up by the wind, which needs to be further improved
