The invention discloses a crawler-type transplanting hole punching device which comprises a crawler driving shaft, a triangular crawler, a crank sliding block punching mechanism, a wheel set speed reducing mechanism and a rack, the triangular crawler is in transmission with the crawler driving shaft and comprises a walking crawler, a wheel set and a wheel set support, and the two ends of the rack are both fixedly connected with the wheel set support of the triangular crawler. The crank sliding block punching mechanism comprises a crank and a sliding block, the sliding block is in vertical sliding connection with the machine frame, one end of the crank is fixedly connected with the crawler belt driving shaft, hole thorns are arranged at the lower end of the sliding block, and the wheel set speed reducing mechanism is provided with a brake pad used for conducting friction speed reduction on the wheel set when the hole thorns conduct punching downwards. Through the speed reduction effect of the brake pad of the wheel set speed reduction mechanism during punching, the speed of the hole thorns in the walking direction is reduced, it is ensured that vertical holes are punched vertically and close to each other as much as possible in the punching process, the punching efficiency and the punching quality are improved, and then automatic punching operation is achieved in the walking process of the triangular crawler belt.
本发明公开了一种履带式移栽孔打孔装置,包括履带驱动轴、三角履带、曲柄滑块打孔机构、轮组减速机构和机架,三角履带与履带驱动轴传动,三角履带包括行走履带、轮组和轮组支架,机架的两端均与一三角履带的轮组支架固接,曲柄滑块打孔机构包括曲柄和滑块,滑块与机架上下滑接,曲柄的一端与履带驱动轴固接,滑块的下端设置有孔刺,轮组减速机构设置有用于当孔刺向下打孔时对轮组摩擦减速的刹车片。本发明通过轮组减速机构的刹车片在打孔时的减速作用,从而孔刺在行走方向降低速度,确保在打孔的过程中尽量向直上直下打出竖直孔靠近,提高了打孔效率和打孔的质量,进而实现三角履带在行走的过程中实现自动化打孔作业。
