Fish-scale pit furrowing device

Abstract

The invention relates to a soil preparation furrowing device for forest planting of the forest industry, and relates to a furrowing device which is particularly suitable for the artificial forest planting in a large-area fish-scale pit way on low-pitched land in arid and semi-arid planting areas. The fish-scale pit furrowing device mainly comprises a plough body (1), a deep-digging cutter (2), a side-wall cutter (3), a measure and control land wheel (10), a main frame (4), a three-point suspension rack (7), an electric control system and a hydraulic control system, wherein the electric control system transmits signals about the furrowing size of each fish-scale pit and a distance size between every two adjacent fish-scale pits on the ground to an electric control box system through an electric sensing plate on the measure and control land wheel (10) to further control the hydraulic control system, so that the plough body (1) and the side-wall cutter (3) on a rear frame act from top to bottom according to the control requirements. The fish-scale pit furrowing device has advantages that the fish scale pit furrowing device can be connected with any tractor with 120horsepower or more in China, the overall layout of the structure is reasonable, the hydraulic system is simple, and convenience and reliability in transmission can be realized; and the distance measuring precision of the fish-scale pit is high, and the size of the pit can be adjusted at any time.

Description

technical field [0001] The invention relates to a ditching device for forestry afforestation and land preparation, and is particularly suitable for ditching equipment used for artificial afforestation in the form of large scale fish scale pits on gentle slopes in arid and semi-arid afforestation areas. Background technique [0002] In most of the arid and semi-arid areas in my country, due to the influence of the monsoon climate, the rainfall is too concentrated and unevenly distributed in time and space, resulting in severe drought and seasonal drought all year round. Most of the flood seasons in this area are concentrated in July-September every year. The rainfall accounts for 60%-80% of the whole year. Although the rainfall is small, strong showers are common. In this case, it rains heavily and runoff quickly forms on the surface. However, most of the rainwater cannot be absorbed by the soil and is lost in vain, about 2 / 3 of which is surface runoff. How to allocate and u...
