Combined soil preparing machine
Technical field
The utility model belongs to agricultural and ploughs scarification equipment, is specifically related to a kind of combined soil preparing machine.
Background technology
At present, most combined soil preparing machines are the cultivated scarification equipments that are used for ridge formula operation by tractor-drawn, its type of belt drive mainly contains the transmission case that drives rotor and is positioned at the frame outside, and transmission case is positioned at that the frame inboard is offset to furrow or transmission case is positioned at three kinds of forms of frame central authorities.Its defective is: 1, transmission case is positioned at the soil preparation machine in the frame outside, and the ridge phenomenon can appear scraping in transmission case, be about to the good ridge platform of farming and scratch, and the both sides tilling depth is inconsistent.2, transmission case is positioned at the transfer case of the frame inboard and the furrow of setovering, and its frame lays particular stress on and can cause tilling depth inconsistent.3 and transmission case is positioned at frame when central authorities, when farming odd number ridge, because the tractor structure characteristics, transfer case can be positioned at platform top, ridge, cause tilling depth to cross shallow and ridge platform plough-leaking phenomenon, and also there are a common problem in above-mentioned three kinds of types, are exactly that every rotary tillage rotor and stubble-cleaning rotor are driven by a transmission case and connect, when the farming fabric width surpasses 5 ridges, the farming axle can be long, intensity descends, and causes dependability to descend, and can't satisfy agriculture requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of rotary tillage rotor and stubble-cleaning rotor to drive connection by two transmission cases, can guarantee the tilling depth unanimity, does not scrape the ridge, farming rotor suitable length, the combined soil preparing machine that intensity is good.
For achieving the above object, the utility model comprises frame, driving headstock, transfer case, rotary tillage rotor, stubble-cleaning rotor, gripper shoe, deep soil loosing shovel, ridging device, hanger bracket.Driving headstock is fixed on the upper center of frame, and the two ends of the power take-off of driving headstock are provided with spline; Transfer case is fixed on the frame inboard, splits the furrow position in the driving headstock both sides; The power take-off of driving headstock connects with the power input shaft of both sides transfer case; Be provided with gear train in each transfer case, transfer case internal gear power the most at last reaches rotary tillage splined shaft and the stubble-cleaning splined shaft that be arranged in parallel before and after the transfer case bottom; Rotary tillage splined shaft and stubble-cleaning splined shaft two ends are provided with spline, connect with rotary tillage rotor and stubble-cleaning rotor respectively and drive rotor work by spline; The rotary tillage rotor connects by the rotary tillage splined shaft of two transfer case bottoms, and the stubble-cleaning rotor connects by the stubble-cleaning splined shaft of two transfer case bottoms; Stubble-cleaning rotor and rotary tillage rotor front and back below frame be arranged in parallel; Deep soil loosing shovel is fixed on the central sill of frame, between rotary tillage rotor and the stubble-cleaning rotor; The ridging device is installed on the frame back rest, rotary tillage rotor rear.
Beneficial effect
Two transfer cases of the present utility model are positioned at the frame inboard, and the ridge, is not scraped at rack construction symmetry, tilling depth unanimity in the driving headstock both sides; Rotary tillage rotor and stubble-cleaning rotor drive connection jointly by two transfer cases of driving headstock both sides, suitable length, and intensity is good, and the complete machine operation is reliable.

Embodiment
As shown in the figure, the utility model comprises frame 1, driving headstock 2, transfer case 4, rotary tillage rotor 6, stubble-cleaning rotor 5, gripper shoe 7, deep soil loosing shovel 8, ridging device 9, hanger bracket 10.Frame 1 is the rectangle steel structure, plays the supporting anastomosis, and driving headstock 2 is fixed on the upper center of frame 1, and the two ends of the power take-off 12 of driving headstock 2 are provided with spline, and power take-off 12 connects with the power input shaft 13 of both sides transfer case 4; Two transfer cases are fixed on the frame inboard, split the furrow position in the driving headstock both sides; Be provided with gear train in each transfer case 4, gear train in the transfer case 4 power the most at last reaches transfer case 4 bottom rotary tillage splined shaft 19 and stubble-cleaning splined shafts 18, and rotary tillage splined shaft 19 and stubble-cleaning splined shaft 18 two ends are provided with spline and connect with rotary tillage rotor 6 and stubble-cleaning rotor 5 respectively and drive the rotor rotary work; Rotary tillage rotor 6 and stubble-cleaning rotor 5 front and back below frame be arranged in parallel; Deep soil loosing shovel 8 is fixed on the central sill of frame 1, between rotary tillage rotor 6 and the stubble-cleaning rotor 5; Ridging device 9 is installed on the frame back rest, rotary tillage rotor 6 rears.
Its course of work is that tractor is hooked together by hanger bracket 10 and combined soil preparing machine, provides the power traction operation by tractor.Tractor passes to one 16 of driving headstock with power, drives the case internal gear and rotates, and a pair of intermeshing bevel gear 11 is set in the driving headstock 2, and the gear driven power take-offs 12 in the driving headstock 2 rotate; Power take-off 12 connects with the power input shaft 13 of both sides transfer case, import power into transfer case 4, by the transfer case gear train power is reached transfer case 4 bottom rotary tillage splined shaft 19 and stubble-cleaning splined shafts 18 again, rotary tillage splined shaft 19 and stubble-cleaning splined shaft 18 drive rotary tillage rotor 6 and stubble-cleaning rotor 5 rotary works respectively.
