Description

A tea ridge ditch soil loosening device

Technical Field

The utility model relates to the technical field of soil loosening equipment, in particular to a tea ridge ditch soil loosening device.

Background Art

In a tea garden, the roots of tea generally grow in all directions after planting. For better growth of tea, the tea ridges and ditches between the tea ridges need to be loosened intermittently. Generally, a tea garden tiller is used to loosen the soil in the tea ridges and ditches. Currently, most of the existing tea garden tillers use micro-tillage machines and small farm management machines to loosen the soil, such as a mountain tea garden fertilization loosening device with application number 202321981497.0. This device usually uses a rotary tiller to cut the soil at high speed to achieve the purpose of loosening the soil. However, because it is not a continuous rotary cutting, but an intermittent dislocation rotary cutting structure, the impact reaction force generated when the soil is rotary cut is large, and it is balanced by the weight of the tiller itself, so there are problems such as large vibration, poor stability, and difficult direction control, especially for hardened, compacted soil and soil containing small stones. The loosening effect is poor. In addition, some equipment uses eccentric or crankshaft structures to drive steel forks and other workpieces to turn over or dig the soil, but this structure is large in size and heavy in weight, and is not suitable for use in sloping tea gardens without mechanized farming roads. Moreover, the soil after operation becomes irregular blocks and the soil structure is large, which cannot achieve the ideal state of small particles, fine and uniform, loose and breathable soil required for the growth of tea trees.

In addition, the existing application number is 201922104231.8, a portable soil loosening device for fertilizing a mountain tea garden, comprising two side plates, a connecting plate is fixedly installed on the top of the two side plates, and the same moving seat is slidably installed on the side where the two side plates are close to each other, a threaded groove is opened on the top of the moving seat, a rotating hole is opened on the top of the connecting plate, a screw rod is rotatably installed in the rotating hole, the screw rod is threadedly installed in the threaded groove, a turntable is fixedly installed on the top of the screw rod, and the turntable is rotatably installed on the top of the connecting plate, two rotating grooves are opened at the bottom of the moving seat, spiral rods are rotatably installed in the two rotating grooves, and the two spiral rods are fixedly sleeved with a first bevel gear, two mounting seats are fixedly installed at the bottom of the moving seat, and rotating rods are rotatably installed on the two mounting seats, and the ends of the two rotating rods close to each other are fixedly installed with a second bevel gear, and the second bevel gear is meshed with the corresponding first bevel gear, and the ends of the two rotating rods away from each other are fixedly installed with gears, and the sides of the two side plates close to each other are fixedly connected with racks, and the racks are meshed with the corresponding gears. The portable soil loosening device loosens the soil by moving two vertically arranged spiral rods downward and rotating at the same time. During the soil loosening process, the vertically arranged spiral rods have great resistance when pushed forward, making the operation difficult and the construction efficiency low.
