Abstract
The utility model relates to a double-screw variable-pitch rotary-tillage ridger which comprises depth-limiting regulating mechanisms, a hood, a sprocket drive mechanism, a transmission shaft, a transmission control box, a transmission control handle, a tool rest and a blade, and is characterized in that the depth-limiting regulating mechanisms are fixedly connected at two ends of the rear part of the hood respectively, the transmission shaft is arranged at the inner side of the upper part of the hood, the transmission control box is connected on the transmission shaft, a transmission control handle is connected on the transmission control box, two ends of the transmission shaft are both connected to the upper part of the sprocket drive mechanism, two ends of the tool rest are both connected to the lower part of the sprocket drive mechanism, the tool rest is symmetrically provided with two double-screw structures with reverse directions, the screw pitch of each double-screw structures is gradually enlarged from two ends of the tool rest to the middle, and the blade is connected on a helical line of the double-screw structure of the tool rest. The double-screw variable-pitch rotary-ridger is reasonable in structure, reliable in operation quality, good in interchangeability, convenient to maintain, simple and convenient to operate, and reasonable in design, thereby being an ideal soil preparation machine.
Description
Technical field
The utility model relates to a kind of rotary tillage ridger, relates in particular to a kind of double helix displacement rotary tillage ridger.
Background technology
Rotary tillage ridger is that development in recent years is got up for the tillage machinery such as dry crops such as tobacco leaf, vegetables, cotton, rapes, plays very important effect aspect peasant's labour intensity promoting agricultural production efficiency and alleviate.The at present domestic single-screw rotary tillage ridger that generally uses comes with some shortcomings, be mainly manifested in: exist cutter shaft to twine the problem of grass during operation, because single coil configuration, so that at when work ridging cutter single load bearing, cause the situation that ridge shape uniformity is poor and the coefficient of variation is large, even the phenomenon of machine when work sideslip occurs.
Summary of the invention
The purpose of this utility model is to provide a kind of ridging good stability, convenient and practical double helix displacement rotary tillage ridger.
The utility model is achieved like this, it comprises the depth stop guiding mechanism, hood, chain wheel driving mechanism, power transmission shaft, the transmission control cabinet, the transmission joystick, knife rest and blade, it is characterized in that two ends, hood rear portion all are fixedly connected with a depth stop guiding mechanism, the hood upper inner is provided with power transmission shaft, be connected with the transmission control cabinet on the power transmission shaft, be connected with a transmission joystick on the transmission control cabinet, the power transmission shaft two ends all are connected to the top of chain wheel driving mechanism, the two ends of knife rest all are connected to the bottom of chain wheel driving mechanism, knife rest is arranged with two each other opposite direction double-spiral structures, and double-stranded pitch is from the knife rest two ends toward the centre and increases gradually, and blade is connected on the double-stranded helix of knife rest.
Technique effect of the present utility model is: blade is symmetrically arranged, make mechanism's stress balance, the riding stability that is conducive to ridger, the position meeting spatial varying pitch double helix rule of knife rest, this arrangement is conducive to regulate each regional soil conveying capacity of workpiece, efficiently solves the problem that ridge shape uniformity is poor and the coefficient of variation is large, and rotary blade and ridging cutter are loaded in mixture on tool axis, wherein rotary blade can improve the soil breaking effect, and can effectively reduce the careless phenomenon of twining of axle.A kind of double helix displacement of the utility model rotary tillage ridger is rational in infrastructure, and operation quality is reliable, and interchangeability is good, is convenient to maintaining, and is easy and simple to handle, and reasonable price is desirable tillage operation machinery.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the drawings, 1, depth stop guiding mechanism 2, hood 3, chain wheel driving mechanism 4, power transmission shaft 5, transmission control cabinet 6, transmission joystick 7, knife rest 8, blade.
Embodiment
As shown in Figure 1, it comprises depth stop guiding mechanism 1, hood 2, chain wheel driving mechanism 3, power transmission shaft 4, transmission control cabinet 5, transmission joystick 6, knife rest 7 and blade 8, two ends, hood 2 rear portion all are fixedly connected with a depth stop guiding mechanism 1, hood 2 upper inner are provided with power transmission shaft 4, be connected with transmission control cabinet 5 on the power transmission shaft 4, be connected with a transmission joystick 6 on the transmission control cabinet 5, power transmission shaft 4 two ends all are connected to the top of chain wheel driving mechanism 3, the two ends of knife rest 7 all are connected to the bottom of chain wheel driving mechanism 3, knife rest 7 is arranged with two each other opposite direction double-spiral structures, and double-stranded pitch is from knife rest 7 two ends toward the centre and increases gradually, and blade 8 is connected on the double-stranded helix of knife rest 7; In use, power transmission shaft 4 rotates under transmission control cabinet 5 and 6 controls of transmission joystick, drive chain wheel driving mechanism 3,7 rotations of chain wheel driving mechanism 3 band movable knife racks, the blade 8 beginning rotary works on the knife rest 7 are by the degree of depth of depth stop guiding mechanism 1 control blade 8 work, because blade 8 is symmetrical each other opposite direction double-spiral structure, so that along knife rest 7 direction cutters 8 stress balances, guaranteed the stationarity of work, deviation phenomenon can not occur; Rotary blade and ridging cutter can be loaded in mixture on tool axis simultaneously, wherein rotary blade can improve the soil breaking effect.
