Description

Cutter special for hard land of mini-tiller

Technical Field

The utility model relates to a plough quick-witted cutter technical field a little, particularly, relate to a plough quick-witted special cutter in hard ground a little.

Background

The mini-tiller uses a small diesel engine or a gasoline engine as power and has the characteristics of light weight, small volume, simple structure and the like. The micro-tillage machine is widely applicable to dry lands, paddy fields, orchards and the like in plains, mountainous areas and hills. The tractor-trailer can be used for pumping water, generating electricity, spraying pesticide, spraying and the like by matching with corresponding machines, can also be used for towing the trailer for short-distance transportation, can be freely run in the field by a mini-tiller, is convenient for users to use and store, saves the trouble that large agricultural machinery cannot enter mountain fields, and is the best choice for vast farmers to replace cattle farming.

The micro-tillage machine is suitable for dry land, paddy field, orchard and vegetable land in plains, mountainous areas and hills, can perform shallow rotary tillage, plowing, ditching, ridging and the like at present, but is not suitable for operation on hard-geological terrain because of small volume and small power and no special hard land cutter, can only be used for operation on loose sandy soil, and the rotary tillage machine is required for hard land operation, but is not suitable for operation on small-terrain farmland because of large weight and large volume. In addition, the cutter of the traditional mini-tiller is easily wound by weeds during tilling and is often cleaned manually. Particularly in areas with a large number of weeds, the cutter and the rotating shaft are wound by the weeds, which results in low cultivation efficiency, shallow cultivation depth, heavy loading of the prime mover, and the like.

Therefore, a special hard-ground cutter of the micro-cultivator needs to be designed to solve the problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a plough quick-witted special cutter in hard ground a little, it can directly beat out soil granule, supplies to grow seedlings and uses soil, realizes that the miniwatt plough quick-witted a little and beats hard ground, solves to plough the machine a little and does not have hard ground cutter, can not be used for the defect in hard ground, still has the anti-winding characteristic simultaneously, can prevent that cutter self from being twined by weeds.

The embodiment of the utility model is realized like this:

the embodiment of the application provides a plough quick-witted special cutter in hard ground a little, it includes pivot, knife rest and first blade, the pivot set up in the inside of knife rest, follow on the knife rest the pivot axial is provided with a plurality of frame roof beams, arbitrary all be provided with on the frame roof beam first blade, the crooked setting in sword belly direction is followed at the top of first blade, the cutting edge of first blade is followed the pivot is radially set up.

When the utility model is used, the rotating shaft is connected with the driving shaft on the micro-cultivator, and the rotating direction of the rotating shaft is consistent with the direction of the cutting edge of the first blade; when the tillage operation is started, the first blade and the bending part on the blade tip can effectively break out small soil granules from hard soil, and the side edge of the frame beam can assist in tillage when the blade rotates, so that the tillage efficiency of the mini-tiller is improved.

The utility model discloses a first blade that sets up on frame roof beam and the frame roof beam, and the top of first blade sets up along the bending of sword belly direction, can directly beat out soil granule, supplies to grow seedlings and uses soil, realizes that the miniwatt machine of ploughing a little beats hard ground, solves to plough a little machine do not have hard ground cutter, can not be used for the defect on hard ground, the top of first blade is crooked and with the setting of first blade fall by mistake, makes whole cutter have the characteristic of preventing twining, can prevent that cutter self from being twined by weeds.

In some embodiments of the present invention, the left end of the tool rest is provided with a circular side frame, and one end of the frame beam is fixedly connected to the circular side frame.
