Abstract
The utility model relates to a rotary tilling machine, which comprises a center driving gear box, a right beam pipe, a left beam pipe, a driving shaft, a side edge driving case, a lateral plate, a cutter shaft, a mudguard, a three-point suspension bracket, a three-arm type fixer which uses the middle, the left and the right arms to respectively connect with the connecting ear of the suspension bracket, and connecting boards on the left and the right beam pipes, and a double-vane furrow opener in the type of a plough. The double-vane furrow opener in the type of a plough is provided with a handle which is provided with depth adjustment holes and is installed in a fixed sleeve having a plurality of depth adjustment holes in the three-arm type fixer. The utility model can be accomplished by modifying simply the original rotary tilling machine, and has the advantages of simple operation, short converting time of the machine type, low labor intensity, etc.
Description
The utility model is about agricultural machinery, particularly about being with the scarification equipment of driving type rotation and non-rotating workpiece.
Rotovator is a kind of ground-working equipment with rotary driven tool, turns over and operation in small, broken bits in the soil that it is widely used in before the sowing.Update along with agrotechnical, many crops require at the furrow upper seeding wheel, this means to carry out rotary tillage and trench digging bedding two subjobs respectively, need supporting two kinds of facility.People have developed many rotary tillages, trench digging combined working machine for reducing the operation number of times, increase work efficiency and reducing equipment investment.These facility all are the ditching component that increases a rotation on the basis of rotovator.Above-mentioned ditching component is installed in the rotary tiller shaft middle part, so the cutter shaft middle part is stressed greater than the normal rotary tillage resistance in both sides, so cutter shaft is easily broken.And the trench digging degree of depth can not be adjusted by the decision of the rotary tillage degree of depth.When this in addition combined working machine only is used for the rotary tillage operation, must be from new replacing cutter shaft, dismounting is inconvenience very.
The purpose of this utility model is to provide a kind of rotovator with ditching component, and its ditching component and cutter shaft are irrelevant, trench digging depth-adjustment, easy accessibility.
The purpose of this utility model is achieved in that a kind of central driver gear case that comprises, right Guan Liang, left side Guan Liang, power transmission shaft, side driving box, side plate, cutter shaft, the rotovator of dashboard, it is characterized in that being provided with double-wing-ploughshare ditcher and tri-arm fixator, described tri-arm fixator wherein, a left side, right three arms respectively with the hanger bracket connecting ear of central driver gear box top, joint cover on left side Guan Liang and the right Guan Liang is fixed, described double-wing-ploughshare ditcher is provided with the handle with some depth adjustment hole, and described tri-arm fixator is provided with the fixed cover of laying the corresponding depth adjustment of having of above-mentioned handle hole.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the end view of Fig. 1.
Fig. 3 is the signal of rear mudguard opening.
The utility model has comprised the rotovator of being made up of central driver gear case 24, left side pipe beam 17, right pipe beam 22, side driving box 18, side plate 1, cutter shaft 19, front mudguard 2, rear mudguard 4 and trifilar suspension frame 20 as described in Fig. 1 and 2.Right pipe beam 22 connects the casing of central driver gear case 24 mutually with side plate 1.Left side pipe beam 17 connects the casing of central driver gear case 24 mutually with the casing of side driving box 18.Be provided with the power transmission shaft of the transmission of power of central driver gear case 24 being given side driving box 18 in the pipe beam 17 of a left side.Cutter shaft 19 is provided with a series of rotary blade.Cutter shaft 19 is bearing on the bearing of side plate 1 and side driving box 18, one end and connect with spline with tooth/sprocket wheel in the side driving box 18.Trifilar suspension frame 20 links to each other with left side pipe beam 17 and the right beam 22 of managing respectively with the underarm of its both sides, and links to each other with hanger bracket connecting ear 21 on the central driver gear case 24 with its hound.Be respectively arranged with joint cover 15 and 3 on left side pipe beam 17 and the right pipe beam 22.Two hold-down mechanisms 5 that comprise compression spring, strut, coupling sleeve and coupling seat about being provided with the backboard 4 of front apron 2 hinge knot.Each hold-down mechanism 5 nationality two clamping plates 16 is fixed on above-mentioned joint cover 15 and 3.Be provided with double-wing-ploughshare ditcher and tri-arm fixator, tri-arm fixator comprises middle arm 7, left arm 14, right arm 6 and fixed cover 10.Middle arm 7 is screwed on hanger bracket connecting ear 21, and 6 of left arm 14 and right arms are fixed on joint cover 15 and 3 with clamping plate 16 with screw respectively.Double-wing-ploughshare ditcher comprises left wing 12, right flank 8, ploughshare 23, ploughshare wall 9 and 13, handle 11.Ploughshare wall 9 and 13 respectively to the right, the left side curved surface that is symmetry tilts.Hua Bi also can be that the single curved surface that tilts to the back upper place constitutes.Fixed cover 10 and handle 11 are respectively arranged with a series of depth adjustment hole 25.Utilize the relative position in depth adjustment hole double-wing-ploughshare ditcher can be fixed on the desired trench digging degree of depth.The middle part of rear mudguard 4 is provided with breach 26(Fig. 3 that the curved surface with the ploughshare wall 9 of double-wing-ploughshare ditcher and 13 adapts).When the curved surface of Hua Bi is single when the back upper place tilts, breach 26 is trapezoidal.Other is provided with similar to breach 26 shapes and lid that it can be hidden from view.Lid adopts screw, nut to be connected with rear mudguard 4.
The utility model is simple in structure, and it has only done small change to former rotovator, has kept original farming performance of rotovator and due intensity, has enlarged the purposes of rotovator again.It can realize the adjusting of the rotary tillage degree of depth and the trench digging degree of depth on demand easily.In the time need not ditching, can be easily double-wing-ploughshare ditcher be removed or it is stood up and be inserted in the fixed cover 10, with lid breach 26 is stopped up again, can carry out the rotary tillage operation.This is not only easy and simple to handle, has shortened the time of type conversion, and has alleviated tractor driver's labour intensity greatly.
