The invention discloses a wear-resistant excavation vibration cutter device. The wear-resistant excavation vibration cutter device is characterized in that a blade is mounted at the front end of a cutter arm, and a cutter holder is mounted at the rear end of the cutter arm; the cutter holder is a rectangular frame, the front portion and the rear portion of the frame are rotatably connected with afixing part through a double-hole bearing box and a three-hole bearing box, the top end of the three-hole bearing box is in bearing connection with a connecting rod main shaft, the connecting rod mainshaft is parallelly provided with a power input shaft, an eccentric bearing is in key connection to the middle of the power input shaft, a bearing flange sleeves the eccentric bearing, an eccentric connecting rod clamped to the outer edge of the bearing flange in a matched manner is further mounted in the middle of the connecting rod main shaft, and the eccentric connecting rod is fixedly connected to the top-end bearing of the three-hole bearing box. The wear-resistant excavation vibration cutter device has the advantages that the double-hole bearing box and the three-hole bearing box are used to replace wear-resistant sleeves, due to the fact that the bearings are good in wear resistance and strength and high in flexibility, the impact resistance of the device is enhanced, and assembling and maintenance are facilitated; the device is compact in structure, lightweight, low in cost, suitable for being purchased and used by small-scale garlic farmers and extremely high in social and economic value.
Description
technical field [0001] The invention relates to the field of agricultural machinery, and specifically discloses a wear-resistant digging vibrating knife device.
