Description of the Related Art When the furrow soil of a tea plantation solidifies and hardens, the permeability of the soil, the water holding power and the water permeability of the soil decrease, and the respiration of the roots, nutrient absorption and the growth of soil bacteria are reduced. Hindered, negatively affecting the growth of tea trees and reducing the yield of fresh tea leaves. Therefore, in order to improve the above soil physical properties, conventionally, using a trencher-type self-propelled deep tiller,
Tilling hardened soil. The trencher has one end of a boom that is vertically moved by a hydraulic cylinder supplied with hydraulic oil by a hydraulic pump driven by the engine at the rear end of the truck, and is rotatably driven by the engine on the boom. In this method, a chain conveyor with a cutter is wound, and the boom is lowered to a predetermined depth in the ground while rotating the chain conveyor, and the tracker is advanced to dig a groove having a blade width of the cutter.

[0003]

However, the above-mentioned conventional trencher has a work efficiency of 100 in addition to cutting the roots of tea trees in order to dig a relatively deep and wide groove.
m / h, and there is a problem that the vibration is large and adversely affects the operator.

Accordingly, an object of the present invention is to provide a portal-type vehicle traveling across a ridge of a tea plantation by providing a novel soil deep cultivation mechanism to prevent cutting of the roots of the tea tree and to cause large vibrations in the furrow soil. It is an object of the present invention to provide a riding type tea garden deep cultivator capable of deep cultivation with high efficiency, reducing working labor and shortening working time.

It is characterized by comprising an elevating mechanism provided on the vehicle body and a swing mechanism for reciprocatingly swinging the claws of the deep tillage support.

At the time of operation, the riding type tea garden deep cultivator has a deep tillage support provided vertically in front of or behind a gate type vehicle main body running across a ridge of the tea garden. The lifting mechanism lowers the work from a non-working position above the ground to a working position that penetrates into the ground, and the claw at the lower end of the deep tillage column is reciprocated by the swinging mechanism. In other words, the deep tillage prop travels with the gate-shaped vehicle body while reciprocatingly swinging the lower claw, so that the underground soil is crushed by the deep tillage strut, cracks enter the soil, and air permeability and moisture retention are maintained. Soil physical properties such as power and moisture permeability are improved. When the work is completed, the deep plow is raised to the non-working position above the ground by the lifting mechanism, and the swing mechanism is stopped. The improvement of soil physical properties by the deep cultivation promotes root respiration, nutrient absorption and growth of soil bacteria, promotes the growth of tea trees, and increases the yield of fresh tea leaves. Since the riding type tea garden deep cultivator does not dig a trench by digging the soil like a conventional trencher, there is less possibility of cutting the root of the tea tree compared to a trencher or the like,
The soil can be deeply cultivated with high efficiency without large vibration, so that the work labor and the working time can be reduced.

According to a second aspect of the present invention, the riding type tea garden deep cultivator has a liquid fertilizer tank and a pressure feeding means for feeding the liquid fertilizer in the liquid fertilizer tank to the gate-shaped vehicle main body, and the feeding means sends the liquid fertilizer through a hose. A nozzle for spouting the liquid fertilizer is provided at a lower portion of the deep tillage column.

Therefore, liquid fertilizer is simultaneously applied to the soil crushed by the claws 4 and fertilizer can be effectively applied to tea trees, and unlike the case where fertilizer is applied to the soil surface, there is no flow of fertilizer, and pollution of rivers and lakes due to the flow of fertilizer. Can also be prevented. Further, since the wing-shaped claws of the deep-tiling prop 3 are fixed to the deep-tilling props 3 with bolts as described above and have a structure that can be easily attached and detached, when performing only fertilizing without deep-plowing work, the claws 4 are required. It can be used without mounting. In the above embodiment, since the intermittent discharge device 37 is provided in the hose 35, there is an advantage that unnecessary ejection of liquid fertilizer can be eliminated. In the above embodiment, the deep tillage struts are provided on both the left and right sides of the vehicle body, however, one may be provided at the center. Further, the claw of the deep plow may be swung in the left-right direction instead of swinging in the traveling direction, or a combination thereof.
