The invention relates to a rotary
drill type ditching device capable of regulating space between ditches, in particular to ditching and trenching equipment capable of ditching to obtain ditches with certain space and regulating the space between ditches, belongs to the field of farm machinery. The rotary
drill type ditching device comprises a rotary cultivator roller cone, a front cross arm, a rear bracket, a front cross rotating rod with an inner transmission shaft and an outer rotating shaft, a connecting bracket, a space adjusting wheel, a gear set, driving wheels, a
transmission belt and a transmission chain, wherein a motor provides a power
plant with power; the power
plant is connected with the rotary cultivator roller cone through a transmission shaft; the rotary cultivator roller cone transmits power to a
drill rod, the front cross rotating rod can rotate in a rolling manner during the motion of the power
plant, and the drill rod can be driven to be inserted into soil during rotation of the drill, therefore needed pits, ditches or trenches with certain spacing for farming are formed, automatic and continuous ditching with certain spacing is realized, the spacing accuracy is high, the ditching efficiency is high, the space between ditches can be adjusted, the human cost is reduced, the time is shortened, the application scope of the ditching device is enlarged, and the using effect of the ditching device is enhanced, besides, the device has a simple structure and singe power source, and reduces cost.
