Abstract

The invention relates to a preposed type disk ditching machine, and belongs to agricultural machinery matched with a Dongfeng 12 type hand-held tractor. The preposed type disk ditching machine comprises a main frame connected with a hand-held tractor, wherein the main frame is provided with a gearbox body and a depth limiter (slide-trap) which regulates the depth of the ditching machine; and the gearbox body is provided with a clutch plate, a trowel plate and the like. The main frame of the ditching machine connected with the hand-held tractor is horizontally extended forward and bent upward. The gearbox body is installed on the part bent upward. The horizontal height of the ditching machine is improved, so when the tractor runs on the road surface, a soil cutter and a wall cutter installed on the trowel plate of the ditching machine are difficult to touch the ground and do not influence the ditching operation. Through the invention, not only is the running requirement satisfied, but also the service life of the ditching machine is prolonged.

Description

Front positioning type disk furrower mainframe

Disclosed by the invention is the agricultural machinery of ploughing the first furrow as a guideline---front positioning type disk furrower mainframe a kind of and the equipped use of east wind-12 type.

Front-end ditching machine is by the mainframe installation that links to each other with tractor.Gearbox body also is housed on the mainframe, cutterhead and clutch shaft are housed on the gearbox body; Clutch on the clutch shaft by conveyer belt, becomes power on the tractor and transports to cutter axis through gearbox body, cutter axis drives cutterhead, cuts native cutter and the cliff cutter is finished trench digging by some on the cutterhead.Earth separation plate is equipped with in the cutterhead top, and the soil that ditching machine is left flies to both sides after throwing and hitting earth separation plate.Control the degree of depth of ditching by the depth stop (sliding sticking up) that the mainframe front end is equipped with, finish the operation of the trench digging and width of cloth soil.

Dip down after existing front positioning type disk furrower mainframe and hand tractor are equipped Dou (ZL03143950.0) and then go up curvedly, sliding sticking up with the tie point of frame (seen accompanying drawing 1) in the radius of turn of cutterhead.This design has some weak point: one, walking difficulty, hand tractor is after installing front-end ditching machine, anterior gravity is bigger, must wait the weight of balance front and back at equipped rotovator in the rear portion of tractor or drilling machine, the manipulator worker could operate like this. otherwise, the good again machine worker of muscle power, also can't the long-time operation mechanical work.Behind the equipped good balancing machine in hand tractor rear portion.For tractor can normally be travelled on the road surface, just the rotovator tail wheel of rear portion counterweight must be stretched downwards, the rotary blade that makes counterweight machinery is from going out the ground certain altitude.So, the machinery of back counterweight can not influence tractor and normally travels.But, the ditching machine that is installed in the tractor front portion is just a bit low apart from ground, the Dou if frame dips down again, the cutterhead centre-to-centre spacing ground of ditching machine is just very low, some cuttves of installing on the cutterhead almost are will suffer doing ground, and hand tractor travels all right on smooth road surface, once Uneven road, perhaps manipulator worker fatigue, preposition ditching machine will make impact with the ground.Present rural area, rural area all are cement pavements, ditching machine once with cement pavement bump, what break all is furrowing machine knife and cutterhead, more serious is that the gearbox body of ditching machine is broken.

The region of rivers and lakes is the high yield region of paddy rice and winter wheat, is with the more place of ditching machine.The river in rural area is many, foot bridge just can not lack yet, once after machinery installed before and after the tractor, it is just difficult that following bridge is gone up bridge easily, the last bridge gradient is little, and several rural labours draw tractor band traction can also pass a bridge; The gradient is big, has just had no idea, and has only ditching machine is unloaded, and is installing the back of passing a bridge.If mainframe elder generation level protract (see Fig. 2--a), go up then curved install gearbox body (see Fig. 2--b), or upwarp any than level earlier and protract, fewly then a curved some installation gearbox body, so just make the center of cutter-head of machine for making furrows that certain height is overhead arranged, just can solve the difficult problem of walking.

Its two, during operation ditching machine shake big, (ZL01127121.3) in designed depth stop (sliding sticking up) effect of control ditch depth when it not only will play trench digging, but also to play the effect of stablizing fuselage.Because this front-end ditching machine mainframe is a single armed, only there is an arm to connect the jail with hand tractor, steady when also wanting the cutterhead ditching operation.Except the material that improves materials, also want depth stop tie point reasonable in design: arm is short, near apart from tractor, shakiness during the ditching machine operation, shake are big; Brachium a bit, apart from tractor a little further, just can be more surely during the ditching machine operation, ditching machine is shaken will be a little bit smaller.So with regard to depth stop (sliding stick up) tie point be installed in outside the cutterhead radius of turn (see Fig. 2--c) can not only play the dark effect of trench digging limit, the shake in the time of also reducing the ditching machine operation simultaneously makes the dead furrow of leaving more straight, more flat, the more useful draining in bottom.Fig. 1. (1) dongfeng-12 body (2) mainframe is connected (3) from cutterhead (4) belt pulley (5) gearbox body (6) mainframe (7) the dongfeng-12 frame that has a down dip with dongfeng-12.

Fig. 2-a, 2-b, 2-c are wherein several forms of this patent mainframe.(1) curved (5) depth stop (6) tie point (7) gearbox body (8) trowel dish (9) trowel (10) radius of turn of observing and learn from real life is gone up in flat stretch out (4) of dongfeng-12 frame (2) reinforcement (3) frame.

Claims

1. the front positioning type disk furrower that one kind and east wind---12 type hand tractors are equipped:

Gearbox body is equipped with in mainframe and hand tractor connection on the mainframe;

Gearbox body is equipped with the trowel dish, earth separation plate is equipped with in the cutterhead top, the depth stop (see figure 1) of front end dress on mainframe.

2. front positioning type disk furrower: mainframe prolonged before this level protract (see Fig. 2--a, 2--b) go up curved certain angle then.

3. the gearbox body of front positioning type disk furrower: be installed in the mainframe level back of protracting and go up on the curved position (see Fig. 2--b, 2--c).
