Abstract
The utility model provides a device of removing left out plough for rotating tiller with a central gearing which is a cultivation component for an agricultural machinery. The device of removing left out plough for rotating tiller with a central gearing adopts a free joint driving mechanism composed of hollow annular cross shafts to solve the left out plough problem of the rotating tiller with a central gearing. The device of removing left out plough for rotating tiller with a central gearing can make a main driving shaft travel through a transmission rotating tiller to work, and make a transmission deflection rotating cutter-head cultivate soils in the lower part of a center transmission gear box. The device of removing left out plough for rotating tiller with a central gearing successfully solves the left out plough problem of the rotating tiller with a central gearing.
Description
The present invention is a kind of cultivating member of agricultural machinery.
The rotovator of side transmission at present, its drive path is long, and complex structure, cutter shaft two ends moment of torsion differ greatly and tortuous, deviation of gravity center unit center line, thereby be unfavorable for making and using; The rotovator of central authorities' transmission has simple in structure, and center of gravity is placed in the middle, advantages such as cutter shaft two ends torque distribution equilibrium.But its greatest problem is the central driver gear case is positioned at working width central authorities, and the transverse width of its Accounting of institute certificate, cutter tooth can't farming, thereby form the area of balking, and this is unallowed on the agriculture requirement.Therefore abroad to the existing many researchs of this problem, many schemes have been proposed, conclude and get up to be mainly oblique cutter head type and movable blade tooth-like two big classes, problem is all not ideal enough but solution is balked (consulting " agricultural machinery intelligence data " in 1979 third phase the 17th to 22 page of " eliminating the method that the rotation cultivator is balked " literary composition that the first agricultural machinery research institute of Ministry of Machine-Building Industry publishes).Domestic the seventies inventor during at design rotovator series of products, increased a fixing Plow and shoveled to eliminate and balk, can solve the problem of balking more effectively, but the grass-wrapping problem of failing to solve fully.
At the problem that above-mentioned prior art exists, task of the present invention is a kind of simple in structure, cost is low, the elimination of perfect in shape and function is balked new equipment that meets agriculture requirement of design.
Central driven type rotovator of the present invention is eliminated the device of balking and is formed with the universal joint transmission mechanism that hollow and annular cross axle (11) constitutes by rotary tillage cutter tooth driving shaft (3), deflection axle sleeve (2), deflection rotary tillage cutterhead (5) and deflection rotary tillage cutter tooth (6) and by universal-joint fork (9), (10).
Below in conjunction with the described embodiment of accompanying drawing, be further described.
Fig. 1: for a kind of central driven type rotovator is eliminated the structure drawing of device of balking.
Fig. 2: be the part drawing of the hollow and annular cross axle of this device.
With a deflection axle sleeve (2) angled with rotary tillage cutter tooth driving shaft (3), be fixed on central driver gear case (1) the primitive axis socket end lid position with screw, the axial line of the endoporus axial line of deflection axle sleeve (2) and rotary tillage cutter tooth driving shaft (3) coincides, and the driving shaft (3) of rotary tillage cutter tooth can be passed wherein.Deflection rotary tillage cutterhead (5) is enclosed within on the deflection axle sleeve (2), relatively rotates with deflection axle sleeve (2) by ball (4) and adjusting back-up ring (12) deflection rotary tillage cutterhead (5).The stiff end endoporus of cutterhead (5) endoporus two ends and axle sleeve (2) all is equipped with sealing gasket.Deflection rotary tillage cutter tooth (6) is installed on the deflection rotary tillage cutterhead (5) with screw, and the crosscut sword of this cutter tooth bends towards a side of central driver gear case (1).External part at rotary tillage cutter tooth driving shaft (3) is fixed with flange (7) with spline and pin (13), and this dish links to each other with screw with the dish (8) that connects that rotary blade rolls hollow shaft (14) end.Universal-joint fork (9) is an one with flange (7), and universal-joint fork (10) is an one with deflection rotary tillage cutterhead (5), and by the cross axle (11) of universal joint two universal-joint forks is linked together in a known way, forms a universal joint.Universal-joint cross trunnion (11) makes hollow and annular, can make rotary tillage cutter tooth driving shaft (3) pass hollow ring and does not contact.When rotary tillage cutter tooth driving shaft (3) rotates, flange (7) promptly drives and connects dish (8) driven rotary tillage cutter shaft rotation carrying out rotary tillage operation, meanwhile, driving shaft is also by universal joint transmission deflection rotary tillage cutterhead (5) and deflection rotary tillage cutter tooth (6) rotary tillage operation.Because deflection rotary tillage cutterhead (5) tilts all the time, so it is far away that deflection rotary tillage cutter tooth (6) just leaves central driver gear case (1) above forwarding to the time, when forwarding the below to, just can reach the beneath farming of central driver gear case (1), thereby solve the problem of balking of this part fabric width well.
In addition, the angular speed of this deflecting slant cutterhead and the angular speed of driving shaft have difference, so can it be worked below forwarding to by the installation site of cutter tooth on cutterhead the time, have the speedup effect favourable to working.But because the angle excursion of cutterhead is little, difference is very not remarkable.
Compared with the prior art the present invention not only has characteristics simple in structure, that cost is low, and transmission is reasonable, perfect in shape and function.
