Description
Technical field
The utility model belongs to the trench digging dredger of agricultural mechanical field, the two disk milling formula trench digging of especially a kind of variable-ratio dredger.
Background technology
Trench digging, irrigation and ditch cleaning that the trench digging dredger is mainly used in the farmland use, and are wet crop, cotton, the indispensable farm machinery of wheat crop production.What traditional farmland trench digging used is mouldboard plow, and this working method needs tractor that power is provided, and power consumption is bigger, restive depth during trench digging, and rout up taxi and be stirred in grass and can form mud ball and be difficult to cleaning.By retrieval, found that some relate to the public technology of at a high speed two disk furrowers, the spur gear transmission is all adopted in its transmission, and the supporting capacity of transmission case is bigger, thereby causes complete machine too heavy, and the cutterhead rotating speed is lower during operation, has limited operating speed; In addition, existing trench digging dredger because of the difference of geology soft or hard, is very easy to form torque force overload when operation, thereby damages the transmission mechanism in the transmission case.
In addition, and the applicant's a utility model patent (patent name is: two disk milling formula trench digging dredgers, and the patent No. is: 200620151433), this trench digging dredger has solved the problem of present existence effectively; But it is designed to single speed, can not regulate the speed according to actual job operating mode needs.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, transmission is reasonable, reliable, the trench digging desilting efficiency data is high and have the two disk milling formulas trench digging of the variable-ratio dredger of speed changing function.
The utility model is achieved through the following technical solutions:
The two disk milling formula trench digging of a kind of variable-ratio dredger, its main body is by frame, hanger bracket, universal drive shaft, transmission case, the milling cutterhead, crumber, the servo-actuated gauge wheel is formed, wherein universal drive shaft connects the power shaft of transmission case, hanger bracket and transmission case all are packed on the frame, the shaft end of two output shafts of transmission case installs a milling cutterhead respectively, crumber and servo-actuated gauge wheel are installed in the frame rear portion, it is characterized in that: be a cone pulley with driven wheel that power shaft installs mutually in transmission case, the axial switching of this cone pulley is passed through is mounted in change lever on the transmission case.
And described cone pulley is the two-stage cone pulley.
And, a lift cylinder is installed on the described hanger bracket.
And the shaft end of two output shafts of described transmission case installs a milling cutterhead respectively, this two milling cutterheads symmetry and be V-shape and arrange.
Advantage of the present utility model and good effect are:
1. this trench digging dredger adopts same power transmission shaft symmetry to drive two bevel gear modes, can solve effectively that the transmission case volume is excessive, the preponderance problem, and entire mechanism is reasonable in design, and is reliable, improved the rotating speed of milling cutterhead, accelerated operating speed.
2. this trench digging dredger is provided with a cone pulley in transmission case, and it is moving in disalignment to locational string by the control of the change lever on transmission case cone pulley, realize the switching of different rotating speeds, adjustment that thus can perfect realization speed is to be fit to the needs of different work operating mode.
3. the utility model overall structure is simple, and transmission design science is reasonable, and mechanical movement is reliable, has improved the operating efficiency and the operation quality of ditching machine, and adjustable operational, is a kind of agricultural machinery new product that has than high innovation character.

The specific embodiment
Embodiment to utility model of the present invention is further described below in conjunction with accompanying drawing, but is not limited to the concrete structure that present embodiment is narrated.
The two disk milling formula trench digging of a kind of variable-ratio dredger, its main body is made up of frame 3, hanger bracket 1, universal drive shaft 4, transmission case 9, milling cutterhead 7, crumber 10, servo-actuated gauge wheel 12, framework fixed installing hanger bracket wherein, the top of this hanger bracket and the two side ends of frame can articulate with the trifilar suspension of tractor, and this trifilar suspension can rising and falling by trench digging dredger main bodys such as lift cylinder 2 realization frames.Universal drive shaft that level on the frame is installed can with the power of tractor motive power output shaft by bearing support 5 on overload clutch 6 is delivered to power shaft in the transmission case, transmission mechanism in this transmission case as shown in Figure 3, with the driven wheel 16 that power shaft installs mutually are cone pulleys, this cone pulley is two-stage (also can as required for multistage) in the present embodiment, and the two-stage of this cone pulley is switched the change lever of passing through 8 on the transmission case of being mounted in; The engageable gear 17 of slow one-level (shown in Figure 3) as present embodiment, speed is the engageable gear 18 of one-level faster, one of them gears engaged one idle pulley 19 of the two, be fixed with two bevel gear set 21,22 on the power transmission shaft 20 of this idle pulley, the end of the line shaft 15 of drawing by these two bevel gear set symmetry respectively installs the milling cutterhead.These two milling cutterheads are arranged with V-shape, realize that two milling dishes rotate in the same way with work of upmilling mode and throwing soil, the soil of dishing out is dropped on the bank by breast boards 13 retainings that are installed in chaining 14, the ditch of leaving like this forms trapezoidal, the soil that crumber is not just dished out is concentrated to milling disk place, dishes out again, and three-link hitch and servo-actuated gauge wheel mainly are the milling positions of regulating the milling dish, the servo-actuated gauge wheel is packed on the frame, a supporting roller also is installed on it limits dark hydraulic cylinder 11.
The utility model realizes finally that by external impetus (as output shafts such as tractors) deceleration of two milling cutterheads reaches spinfunction in the same way, and adjustable-speed.
