Abstract

The invention provides a micro tillage machine and tillage knife connecting device which comprises a micro tillage machine joint, a connecting rod and a tillage knife joint, wherein a tillage knife mounting hole is formed in the tillage knife joint. The micro tillage machine and tillage knife connecting device further comprises a U-shaped pin rod, a limiting baffle, a spring and a spring baffle, wherein a first pin rod hole is formed in the limiting baffle; a second pin rod hole is formed in the tillage knife joint; the U-shaped pin rod is arranged in the first pin rod hole and the second pin rod hole in a sliding manner; the spring baffle is arranged on the U-shaped pin rod; the spring is arranged on the U-shaped pin rod in a sleeving manner and positioned between the spring baffle and the limiting baffle; a push-pull head is arranged on the U-shaped pin rod. The micro tillage machine and tillage knife connecting device is simple in structure and simple in operation, does not need a special tool during assembly and disassembly and cannot loosen and fall off in the use process, thereby being safe and reliable.

Description

technical field [0001] The invention relates to a micro tillage machine, in particular to a connection device for a tiller blade of a micro tillage machine. Background technique [0002] When the tiller is working, it needs to install the cultivating knife, and when it is not working, it needs to remove the cultivating knife and replace it with walking wheels so as to carry it. The cultivating knife of present tiller generally adopts bolt connection or pin shaft adds jump ring connection. The tiller blades of the tiller are connected by bolts. When installing and removing the tiller blades, special tools (such as spanners or sleeves, etc.) are required to disassemble and install the bolts. The operation is cumbersome, and special tools are required, which increases the cost; The tiller blade of the tiller is connected by a pin shaft and a clip spring. When the tiller is working, the clip spring loosens and falls off due to vibration or is hung up by sundries, so that the pi...
