Abstract

The utility model relates to a vertical rotary tillage head for agriculture, which is mainly composed of a center shaft, a spiral sheet provided with a transverse blade on the lower end, and a vertical blade arranged on the outer edge of the spiral sheet. The utility model not only can vertically and downwards rotate to dig a pit, but also can laterally move and rotate to carry out tillage and furrow opening, when used on a miniature tillage machine, the utility model not only has high efficiency, but also has stable tillage depth.

Description

The vertical type rotary tillage head

The utility model relates to the agricultural tillage facility, particularly the vertical rotating tillage implement.

Miniature agricultural tillage machine is that the degree of depth of plowing that occurs when overcoming turnplow and plowing suddenly is neglected shallow phenomenon deeply, and employing vertical type rotary tillage head is a scheme preferably as its supporting tillage implement.Existing and the supporting rotary cultivator that is used to dig pit of medium-sized tractor mainly is made up of mandrel and the flight that is centered around on this mandrel, there is chisel edge the flight lower end, during rotary work, main by chisel edge cutting soil, this rotary cultivator is suitable for moving downward digs pit, if it is when lateral movement, except that chisel edge cuts off root earth, also need flight to shear the earth that separates direct of travel, this method of operation resistance is big, rotary cultivator easily revolves darker and darker, and the Miniature cultivator used on higher that is unsuitable for low-power is ploughed the usefulness of trench digging.

The purpose of this utility model provides a kind of suitable Miniature cultivator used on higher and is used to the vertical type rotary tillage head of ploughing, ditching.

For achieving the above object, the scheme that the utility model adopts is: the vertical type rotary tillage head has mandrel, on mandrel, center on flight is arranged, chisel edge is arranged at the flight bottom, the flight outer rim is provided with upright sword, when the lateral movement of vertical type rotary tillage head was ploughed or ditched, chisel edge, upright sword downcut earth simultaneously, and are upwards carried by flight.

The cutting edge of above-mentioned upright sword is spent greater than 0 towards the angle α of the tangential direction that rotatablely moves with it, less than 90 degree, so that the earth under the upright sword cutting is fallen on the flight.

In order to improve the rotary cultivator farming efficient of low speed rotation, can be at uniform many upright swords around the flight outer rim; Setting up the bottom in the mandrel bottom has the short flight of chisel edge, and this sheet outer rim also links with upright sword.

Above-mentioned vertical type rotary tillage head can be connected with the scraper plate by the mandrel driven rotary on the mandrel of flight upper end, this scraper plate cooperates the earth that flight is sent up to flow to one side of appointment with supporting fender in its side.

Owing to taked above scheme, the utility model compared with prior art has following beneficial effect:

The rotary cultivator lateral movement that is provided with upright sword is ploughed or during trench digging, chisel edge, upright sword cut earth simultaneously, the efficient height, and the tractive force downward to rotary cultivator is little, and the arable land degree of depth is stable.

Fig. 1 is the utility model structural representation.

Fig. 2 is the cutaway view of Fig. 1.

The utility model is described in further detail below in conjunction with the accompanying drawing example;

1 is the mandrel of vertical type rotary tillage head among the figure, on mandrel 1, center on flight 2 is arranged, there is chisel edge 3 bottom of flight 2, the outer rim of flight 2 is connected with upright sword 4, this connection can be adopted alternate manners such as welding or screw connection, the cutting edge of upright sword 4 is spent greater than 0 towards the angle α of the tangential direction that rotatablely moves with it, less than 90 degree, preferably 10 degree-60 are spent, for improving the rotary cultivator farming efficient of low speed rotation, can uniform many upright swords 4 around flight 2 outer rims, 3-4 bar preferably, also can set up the short flight 5 that there is chisel edge 3 bottom in mandrel 1 bottom, preferably flight 2 is a slices, and short flight 5 is two, the outer rim of short flight 5 also links with upright sword 4, also can be connected with the scraper plate 6 by mandrel 1 driven rotary on the mandrel 1 of flight 2 upper ends, this scraper plate 6 is when being arranged on the supporting use of its peripheral dashboard 7, and the earth that flight 2 is served is swung to the side of arable land direction.
