Problems solved by technology
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 remove and install the bolts. The operation is cumbersome, and special tools are required, which increases the cost; The cultivator blade of the micro tillage machine is connected by a pin shaft and a clip spring. When the micro tillage machine is working, the clip spring loosens and falls off due to vibration or is hung up by sundries, so that the pin shaft falls out of the knife barrel of the tiller blade, and finally the tiller blade falling off, causing a safety accident

Embodiment Construction
[0015] refer to Figure 1 to Figure 5 , the bayonet is used to connect the tiller blade of the tiller to the output shaft (not shown in the figure), the bayonet includes a pin shaft 1 and a wire spring 2, and one end of the pin shaft 1 has a pin for controlling the length of the pin shaft inserted into the output shaft The limit step, which controls the extent to which the pin shaft is inserted into the output shaft. The steel wire spring 2 is bent into two pieces side by side, one end of the steel wire spring 2 is hinged on the pin shaft 1, and this end has a turning section 2b, and the turning section 2b is inserted into the hinge hole 4 of the pin shaft to be hinged, so that the steel wire spring 2 can go around the hinge rotate. Steel wire spring 2 and pin shaft 1 hinged end are merged and stitched together by binding 3 is fixed to prevent the steel wire spring 2 from being stretched and falling, so that the connection is more tightened. The other end of the steel wire...

The invention relates to a connection device of a tillage knife of a mini-tiller. The connection device is characterized in that the tillage knife of the mini-tiller is connected with the output shaft of the mini-tiller through a bayonet lock, the bayonet lock comprises a hinge pin and a steel wire spring, one end of the hinge pin is provided with a limit step used for controlling the length of the inserting output shaft of the hinge pin, one end of the steel wire spring is hinged with the hinge pin, the end combination and splicing position is fixed by binding, the other end of the steel wire spring is triangular, and sides of the triangle are internally tangent to the hinge pin. The device of the invention can be used to install and dismantle the tillage knife without any special tool, the operation is simple, and the connection of the tillage knife of mini-tiller is safer and more reliable.
Description
technical field [0001] The invention relates to the connection of the tiller blade of a micro-tillage machine, in particular to a coupling device of the 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 i...
