A pulling fork is matched with the clutch gear; a pulling rod is matched with a pulling fork and a high/low grinding wheel; one end of a pulling wire is connected with a grinding wheel, while the other end of the pulling wire is connected with a handle which is provided with a rack and a block.

Description

Microtilling machine double rows of teeth wheel drive mechanism

Technical field

The utility model relates to a kind of microtilling machine driving mechanism, especially can work the transmission device that turns to clutch action.

Background technique

At present, known microtilling machine driving mechanism is by single gear transmission, and clutch is contained in bottom on the output shaft, turns to dumbly, uses very inconveniently, easily piles up earth, and mechanism's complexity.

Summary of the invention

In order to overcome existing microtilling machine mechanism complexity, turn to dumb, deficiencies such as operation inconvenience, the technological scheme that its technical problem that solves the utility model adopts is: in transmission case body, all gears and axle are arranged from top to bottom, the duplex tooth is with fast, slowly keep off the tooth engagement, driving tooth and driven tooth often mesh, the small gear that two one sides have several shrinkage pools leans against the driven tooth both sides respectively, the clutch tooth that two one sides have several recessed pawls leans against the one side that two small gears have shrinkage pool respectively, a spline passes two clutch teeth, two small gears, 1 follower, polished rod cooperates with the small gear unthreaded hole on the splined shaft, the spline tooth of splined shaft and driven tooth, the inner splined hole of clutch tooth cooperates, and two small gears often mesh with following two gearwheels respectively, two gearwheels are contained on the same optical axis, and often mesh with following two driving cogs respectively, two driving cogs are equipped with the spline of semiaxis respectively, and shift fork cooperates with the clutch tooth.

The utility model comprises: two shift forks are connected with two pull bars respectively again, and pull bar one end stretches out casing and is connected with the operating device of outside.Operating device by end face by emery wheel, spring, the set lever of High and low type shape form, set lever is made up of handle, tooth bar, fixture block etc.

The utility model comprises that also two semiaxis, two ends cooperate in casing, two ends are stretched out casing and connected cultivated wheel, and the interior semiaxis boss head of casing puts in the circular hole of another root semiaxis, two driving gear mutual sheathing.

The beneficial effects of the utility model are: clutch mechanism is influenced by earth when being difficult for farming on casing top, and flexible operation, convenience, simple in structure further specify the utility model below in conjunction with drawings and Examples:
