Description

A kind of straw crop uprooting and cutting machine

The utility model belongs to crop cropper tool field, relates in particular to the uprooting and cutting machine tool of a kind of straw crops.

At present, when harvesting straw crops such as corn, Chinese sorghum, the one, manually utilize the shallow plane harvesting of short handle pick, time-consuming, the effort efficiency is low; The 2nd, utilize Straw cutting machine when harvesting directly with the straw mincing and returning to the field of crop, the 9Q-2 type Straw cutting machine of producing as Ji County, Hebei farm build machine factory etc., this machinery can only cut ground straw part, and the whole stubble of crop stays in ground, causes whole ground difficulty.And during operation, uneven in length to the cutting of straw, be difficult to during the arable land it is ploughed under in the soil, of poor quality wholely, influence the sowing of winter wheat and emerge and cause the underproduction.The straw of crops is the biogas generating pit filler that extensively promote in a kind of good animal feeding-stuff and rural area in addition.The direct chopping and returning of straw, not only unfavorable to the sowing of crop, and be waste to the straw resource.

The purpose of this utility model just provides a kind of straw crop uprooting and cutting machine tool, and it is particularly suitable for the dynamic power machine with fraction horsepower, and it can intactly fall the straw chipping with stubble, for the reasonable utilization of straw provides condition, and is convenient to meticulous whole ground.

The purpose of this utility model is achieved in that a kind of straw crop uprooting and cutting machine comprises;

Fixedly connected mechanism: whippletree that is with two bobbins and two are used for the U type screw rod that bobbin is fixed with the preceding thick stick of dynamic power machine, the both sides of whippletree respectively have 2-8 to adjust the hole;

Harvesting mechanism: a pair of steel plate perching knife, be fixed on by screw on the relieving tool post of the outer splayed configuration of one-tenth that is connected with steel pole, steel pole penetrates in the steel pipe of welding one sleeve pipe, and fix by the screw of mutually perpendicular direction, be drilled with the hole, garden on the sleeve pipe, and the two ends of being inserted in the whippletree 1 of fixedly connected mechanism, fixing with it by screw rod; On the steel pipe with the garden type pipe box that is welded with one one side band screw on the vertical direction of ground;

Guiding mechanism: the montant that the lower end is fixed with locating wheel passes described garden type pipe box and can adjust its position up and down, is fixedly connected with a straw driving lever and two chain ropes that are connected with the elevator of flexible mechanical between the upper end of two montants.

Its additional technical feature is: the screw at the two ends of relieving tool post, an one hole are lonely shape hole; Have four screw holes that spacing equates on the perching knife; One spill garden ring is arranged on two bobbins; The ultimate range of adjusting the hole is 60cm for the 1m minimum range.

The crop stalk uprooting and cutting machine that the utility model proposed, compare with Straw cutting machine with hand harvest of the prior art and to have: it can intactly shovel and cut straw, make it reasonably to be utilized, avoided because of direct mincing and returning to the field, and influenced the sowing of other crops, the shortcoming of growth.And advantages such as shovel cuts the efficient height, and device structure is simple.

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

Fig. 1 is the structure chart according to the crop stalk uprooting and cutting machine that the utility model proposes.

Below in conjunction with accompanying drawing structure of the present utility model and use principle are described in further detail:

As shown in Figure 1, the crop stalk grain header is by with the fixedly connected mechanism of thick stick before the tractor, and straw uprooting and cutting machine structure and guiding mechanism thereof are formed.

Its detailed structure is: the straw uprooting and cutting machine is snapped in the groove 5 that is enclosed within two bobbins 4 in the whippletree 1 the preceding thick stick with tractor by U type screw rod 3 fixedly connected.Whippletree 1 can rotate in bobbin 4, and the pipe box 16 that a welded still pipe 15 respectively is inserted at its two ends is fixing with whippletree 1 by screw rod 17, and can adjust the distance of 16 of pipe boxes by the adjustment hole 6 of both sides on the whippletree 1.The steel pole 14 of two welding perching knife knife rests 7 inserts in the steel pipes 15, and is fixed by orthogonal screw, 7 one-tenth outer splayed configurations of two perching knife knife rests, and perching knife 8 is fixed on the knife rest 7, and equidistant on the perching knife 8 have four screws 12.Arbitrary screw on the knife rest but preferably the screw in back be lonely shape hole 9, be used for adjusting the position and the angle of perching knife 8 according to action need.On steel pipe 15, fix the vertical tube 2 that a sleeve pipe 18, has locating wheel 10 and passed pipe box 16, and can adjust the height of locating wheel 10.Be fixed with the straw driving lever 11 that can adjust width between the top of two vertical tubes 2, the chain rope of being fixed simultaneously 13 connects with the elevator of tractor respectively.

During use,, adjust the work range of perching knife 8 by adjusting the width of two steel pipes 15 on whippletree 1 according to the amplitude of straw plantation.It adjusts the adjustable range 0.6m～1m of screw 6, adjusts the angle of perching knife 8 again according to the size of straw root stubble, adjusts the height of roller 10 then, makes perching knife incision land for building.Tractor promotes uprooting and cutting machine and moves ahead, perching knife 8 the root stubble of straw is shoveled and hold together it by the straw driving lever before fall.Finish the shovel cut after, grain header gets final product it pull-up by the elevating mechanism of chain rope 13 by tractor.The straw of slide tackling collects or as livestock forage grass or as the filler of biogas generating pit, so that reach the purpose that it makes full use of.

The straw crop uprooting and cutting machine that the utility model proposes, simple in structure, be particularly suitable in the existing family-contract responsibility system farmland covered by contract, utilize the use that is used as power of the four-wheel tractor of fraction horsepower or hand tractor
