Deep cultivator for tea garden

Abstract

The invention relates to a deep cultivator for a tea garden and belongs to the technical field of agricultural and forestry machinery. The deep cultivator comprises a rack and a crankshaft, wherein the crankshaft is arranged on the rack and capable of being connected with an external power output end, the crankshaft comprises a main journal and three connecting rod journals which are connected with the main journal through a crank arm, the three connecting rod journals are arranged in the middle and two ends of the crankshaft respectively, the included angle formed by two adjacent connecting rod journals on the axial projection plane of the main journal is 120 degrees, rockers located below the crankshaft are hinged on the rack, a connecting rod is hinged between each connecting rod journal and each rocker, the crankshaft, the rockers, the connecting rods and the rack form a crank-rocker mechanism, and the connecting rods are provided with hoeing teeth extending downwards. According to the deep cultivator for the tea garden, the hoeing teeth dig and throw soil below evenly and at intervals, growth and development of tea tree roots are facilitated, simultaneously, the working efficiency of deep tillage is improved, and labor is saved.

Description

technical field [0001] The invention relates to a deep plowing management machine, which belongs to the technical field of agricultural and forestry machinery. Background technique [0002] The tea picking gardens are trampled by tea picking in spring, summer and autumn, the soil between the tea rows is hardened, the permeability is poor, the soil fertilizer storage function is reduced, the growth and development of the tea tree root system is hindered and it is easy to age, which affects the fertilizer and water absorption function of the root system. It is necessary to go through deep plowing, loosen the soil, increase the porosity of the soil, improve the soil structure, and improve the soil's ability to store fertilizer and water in order to benefit the growth and development of the root system. At the same time, deep plowing can remove weeds, improve soil fertility, reduce the number of overwintering diseases and insect pests of tea trees, benefit the growth of tea tree...

AI Technical Summary

Problems solved by technology

The traditional conventional plow is suitable for general paddy and dry field cultivation, but it is not suitable for deep plowing in tea gardens. It is difficult to reach a depth of more than 25 cm, and after plowing, the soil becomes strips or the ridges are too large to form a ditch and ridge, which is not suitable for tea gardens. deep plowing requirements

In addition, machine rotary tillage cannot meet the requirements of deep plowing in tea gardens. Generally, it can only reach 12 or 3 centimeters at most, and the soil after plowing is too broken, which is not conducive to the growth and development of tea tree roots, and does not meet the requirements of deep plowing in tea gardens.
