Description

The front positioning type disk furrower

The utility model relates to a kind of agricultural machinery, particularly with the front positioning type disk furrower of hand tractor operation.

At present, ditching machine with the walking tractor matching operation, its mainly by frame, clutch, gear-box, cutterhead, tool rest, cut native cutter, cliff cutter, earth separation plate and gauge wheel etc. and form, it is simple in structure, easy and simple to handle, can carry out the ditching operation in nonirrigated farmland, field.But, its transmission system adopts the structure of gear-box and cutterhead direct connection after slowing down, input in the gear-box, output shaft are mainly following two kinds with the connecting mode of gear: the one, and gear adopts singly-bound to cooperate with axle, thereby when trench digging, if touch hard object easily causes the damage of axle; The 2nd, gear is made one with axle, so just make troubles to assembling, and cost is higher, maintenance difficult.In addition, the terminal angle of the earth separation plate of two V-shaped settings is generally 90 degree, and cutting native cutter and cutterhead traffic direction also is 90 degree angles, when operation, easily form long-pending soil in the end of two earth separation plates, and cut soil, the hack effect is not satisfactory, it is inhomogeneous to throw soil, influences its operating efficiency.

The purpose of this utility model be to provide a kind of and walking tractor matching operation, can effectively improve the front positioning type disk furrower in the service life of axle, and effective, the high efficiency of ditching is to overcome the deficiencies in the prior art part.

For achieving the above object, technical solution of the present utility model is: its mainly by frame, clutch, gear-box, cutterhead, tool rest, cut native cutter, cliff cutter, earth separation plate and gauge wheel etc. and form; Power shaft in its gear-box and driving gear, output shaft and driven gear all adopt splined.

Two earth separation plates that are in the shape of the letter V and are provided with, it is not 120-140 degree angle the frame place between the end.

The traffic direction of cutting native cutter and cutterhead is 140-160 degree angle.

The utility model has prolonged the service life of the gear shaft of gear-box effectively, has improved the trench digging effect, has improved operating efficiency.
