Description

A kind of novel corn straw cutting-up stubble-cutting machine

The utility model relates to agricultural mechanical field, relates to a kind of particularly and the supporting corn stalk cutting-up stubble-cutting machine of tractor with small four wheels.

In the prior art, for the upright mincing and returning to the field of corn stalk, the general employing sold the 9Q-2 series of products that country popularizes on the market, the 9Q-2 type wheat and corn straw cutting-up stubble-cutting machine made of the sharp precious agricultural machinery of Handan, Hebei province man Manufacturing Co., Ltd for example, though that it has is simple in structure, the advantage of processing ease, but also there is following shortcoming simultaneously: the one, its vertical diaxon and immovable support layout designs are not too reasonable, corn stalk can not thoroughly shred, straw jam phenomenon appears often, even cause cutter to quit work, clear up this thing, time-consuming; The 2nd, its moving knife tool is long, has both wasted raw material, and shredding efficiency is low again; The 3rd, batch cutter of cutting of bottom is erect setting, the chopping weak effect.Along with the development of society, progress of science and technology, this machine can not satisfy the needs of agricultural production, and people thirst for appearing on the market of a kind of novel corn straw cutting-up stubble-cutting machine, to adapt to the demand of agricultural production.

The purpose of this utility model provides a kind of novel corn straw cutting-up stubble-cutting machine, and it had both had reasonable in design, and the chaffy corn straw reaches the purpose and the high efficiency of stubble-cleaning effectively again.

The purpose of this utility model is achieved in that the main feature of its structure is to be provided with power transmission shaft 4 in the upper end of frame 1, and gear-box 5, belt pulley 3 are housed on it, and the front of frame 1, both sides are provided with auxiliary frame 18, and the back is provided with connecting rod 19; Top, rear portion and both sides in frame 1 are provided with housing 2.In the inside of frame 1, an end of two vertical shafts 8 connects gear-box 5 respectively, and the other end stretches out frame 1 connection bottom and cuts batch cutter 14; Be respectively equipped with disk 12, steel plate 9 on vertical shaft 8, connect cutter piece 11, knife section 10, immovable support 6 setting that matches with it which is provided with ledger-plate 7.

The characteristics of its structure are that several layers of even cutter piece 11 are housed on the setting steel plate 9 of 12 in the disk of vertical shaft 8 top and the bottom, which is provided with knife section 10.

Immovable support

6 and 8 settings triangular in shape of two vertical shafts, and equal apart from the distance of 8 on two vertical shafts.Batch cutter 14 of cutting of its bottom is 45～60 degree with the ground angle.

The utility model is because adopt immovable support to equate with setting triangular in shape of two vertical shafts and distance, so its reasonable in design is avoided corn stalk jam phenomenon, high efficiency; Because it is provided with disk respectively on two vertical shafts, is provided with vertical steel plate therebetween and makees knife rest simultaneously, elongated cutter is short sword and uses the sawtooth blade instead, so it had both saved raw material, shreds effective again; Be that so its cutting scope is big, it is effective to cut stubble because batch cutter of cutting of its bottom is changed into and angle 45～60 degree in ground are provided with by upright setting of heavily fortified point again.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is the structural front view according to the corn stalk cutting-up stubble-cutting machine that the utility model proposes.

Fig. 2 is the structure vertical view according to the corn stalk cutting-up stubble-cutting machine that the utility model proposes.

Fig. 3 is the structure right view according to the corn stalk cutting-up stubble-cutting machine that the utility model proposes.

Fig. 4 is the A-A profile of Fig. 1.

Describe details and working condition in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 according to the novel corn straw cutting-up stubble-cutting machine that the utility model proposes.

This machine comprises frame 1, is provided with horizontal power transmission shaft 4 in the upper end, and two gear-boxes 5 are housed on it, and the one end is equipped with belt wheel 3; Top, rear portion and both sides in frame 1 are respectively equipped with housing 2, with sealed frame 1; Two side lower parts in frame 1 are provided with land wheel 13, to support whole frame 1.The front lower both sides of frame 1 are provided with auxiliary frame 18, prop up corn stalk with gathering; The back is provided with connecting rod 19, to connect the bumper of tractor.In the inside of frame 1, on two vertical shafts 8 disk 12 is housed respectively, vertical steel plate 9 is housed on it makees knife rest, several layers of company's cutter piece 11 are connected on it with sawtooth pattern moving plate 10; Immovable support 6 equates with 8 settings triangular in shape of two vertical shafts and apart from the distance between two vertical shafts, which is provided with ledger-plate 7, its bottom is cut batch cutter 14 usefulness fixtures 16, disk 17, is connected the bottom that cutter piece 15 is connected two vertical shafts 8, and the angle of cutting batch cutter 14 and ground is 45～60 degree.During work, earlier the connecting rod 19 at frame 1 rear portion is connected on the preceding dangerous thick stick of tractor (not drawing among the figure), the back pushes the working site with tractor with it, two row corn stalks are aimed in the body adjustment, pushing away to overtake with this machine again, the knife section that this moment, corn stalk was rotated cuts off and is brought into two row's fixed cutting tool infalls, by in a row revolving cutter and fixed cutting tool is pulverized it, under frame, spill, batch cutter of cutting of bottom is buried by the soil that its cutter takes up the chopping of corn stalk stubble with mince simultaneously, promptly finishes a course of work.

The utility model applied range also can be in order to upright straw cutting stubble-cleaning such as wheat, jowar, and market potential is big, is suitable for popularizing.
