Abstract
The utility model relates to a combination type rotary tillage cutter shaft, which belongs to the technical field of agricultural machinery and comprises a spline shaft in transmission connection with a gearbox, wherein, a hollow main cutter shaft is sleeved on the spline shaft, the spline shaft is matched and fixedly connected with an inner spline at one end of the main cutter shaft, and a movable cutter shaft fixedly provided with a tillage cutter is sleeved at the other end of the main cutter shaft. The utility model has the following benefits: 1. the utility model is simple in structure and can facilitate cutter changing; 2. the gearbox is placed in the middle, and given the equivalent tillage area, a rotary tiller can be decreased in size to be appropriate to carry out operations within an agricultural greenhouse; and 3. the utility model adopts a combination type structure that a rotary tiller can be equipped with different movable cutter shafts, thereby meeting different soil types, agricultural requirements and operating functions.
Description
Technical field
The utility model relates to the farm machinery parts in a kind of industrialized agriculture machinery, and a kind of combined type rotary ploughing cutter shaft of more specifically saying so belongs to agricultural machinery technological field.
Background technology
Farming is an essential step before the agricultural planting, existing turning over and two kinds of operating types of rotary tillage, and wherein rotary tillage is used more generally in industrialized agriculture.At present, be used for installment agriculture growth and plough the existing garden supervisor of soil preparation machine, also have and use common rotovator in the production of land for growing field crops.The former is little owing to power, and operating speed is slow, and tilling depth is more shallow, operation degree in small, broken bits and poor flatness, and availability is lower.Latter's volume is bigger, inconvenient operation, and canopy head and the dingle area of balking is big.And these two kinds of types all can not carry out the quick replacing of cutter shaft.Understand according to the applicant, not seeing as yet so far can be according to soil types, agriculture requirement, satisfy the rotovator of the quick replacing rotary ploughing cutter shaft of different work function (rotary tillage, ridging) needs.
Summary of the invention
The purpose of this utility model is: at the defective that above-mentioned prior art exists, provide a kind of simple in structure, change combined type rotary ploughing cutter shaft convenient, that be suitable for industrialized agriculture.
The utility model is realized by following scheme: a kind of combined type rotary ploughing cutter shaft comprises the splined shaft that is connected with gearbox drive; The hollow operator axle of suit on the described splined shaft, and match with the internal spline of operator axle one end, be fixed together; The other end suit of described operator axle fixedly has the movable cutter shaft of farming cutter.
The utility model further improves, and the termination of described splined shaft has screwed hole, and described operator axle is fixedlyed connected with splined shaft by the hanging screw that is screwed into screwed hole.
The utility model further improves, and the other end of described operator axle is hollow hexa-prism, the six prismatic holes of the endoporus of described movable cutter shaft for matching with it.
The beneficial effects of the utility model are: (1) is simple in structure, tool changing convenient; (2) in the middle of gear-box was placed on, under the situation of same farming area, the rotovator size can reduce, and was fit to operation in the industrialized agriculture canopy; (3) adopt fabricated structure, rotovator can supporting a plurality of different movable cutter shafts, satisfy different soils type, agriculture requirement and operation function.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
The combined type rotary ploughing cutter shaft of present embodiment as shown in drawings, splined shaft 3 pass be positioned at the middle part rotovator gear-box 2, be in transmission connection with it, and be arranged symmetrically in gear-box 2 both sides.Be set with hollow operator axle 1 on the splined shaft 3 of both sides.Operator axle 1 is welded for two sections by pipe and six prismatic pipes.Be inserted with internal spline in the pipe, match, constitute circumferentially constraint with splined shaft 3.The termination of splined shaft 3 is shaped on screwed hole, and hanging screw 6 passes the endoporus of operator axle 1, is screwed into screwed hole, and operator axle 1 is fixedlyed connected with splined shaft 3.Six prismatic pipeline section suits of operator axle 1 also have the first movable cutter shaft 4 and the second movable cutter shaft 5 (a tight bolt plays pressuring action, is not connected with the operator axle) of farming cutter by a tight bolt.The endoporus of the first and second movable cutter shafts 4,5 be and operate the axle 1 six prismatic close-fittings six prismatic holes, thereby can tightly overlap outside it.Dispose different farming cutter 8 (rotary blade, ridging cutter) respectively as required on operator axle 1, the first movable cutter shaft, the second movable cutter shaft.
During this had been implemented, in the middle of the rotovator gear-box was placed on, cutter shaft was suspended from two ends, and the existing mechanism that is placed on two ends than gear-box saves the space, has increased the rotary tillage working area.When needing to change cutter shaft, rotovator end face baffle plate is taken off, unclamp the tight bolt on the first and second movable cutter shafts, just can change easily.
In addition to the implementation, the utility model can also have other embodiments.For example, six prismatic pipes also can replace with four ribs or pentagonal prism pipe.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
