Description

Dual-purpose side case of biax

Technical Field

The utility model belongs to the technical field of agricultural machine, concretely relates to dual-purpose side case of biax.

Background

The rotary cultivator of the agricultural machine is used most and is also the most common, and rotary tillage and straw returning can be realized. Can divide into corotation and reversal two kinds according to turning to of rotary cultivator cutter axle and tractor wheel, corotation: the working load of the tractor is lighter than that of reversal, the operation speed is higher than that of reversal, the farmland efficiency is higher, but the farmland soil crushing effect is not as good as that of reversal; reversing: the workload is much heavier than forward rotation because the counter-rotating arbor will give the tractor a reaction force. One force is forward and the other force is backward, which is equivalent to tug of the river of a tractor, and the power consumption is at least about 30 percent more than that of the forward rotation, namely the oil consumption is greatly increased.

In actual use, according to the needs of agricultural operation, the rotation and the reversal are required to be switched for use, for example, the reversal has the biggest advantages and benefits that the stubble cleaning and the stirring of farmlands are better, the operation speed of a tractor is slow, so that soil and straws can be fully beaten, and the crushing effect is better; most of the conventional rotary cultivators rotate positively and have positive and negative rotating gear boxes and other structures for realizing positive and negative rotation at present, but the transformation cost is higher, and the adjustment is more troublesome when the rotary cultivator is used.

Disclosure of Invention

An object of the utility model is to design a dual-purpose side case of biax, can select behind the output power the utility model discloses one or two axles of side case can obtain reversal or corotation.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

the utility model provides a dual-purpose side case of biax, includes the box, its characterized in that: the left end of the box body is provided with a first input shaft and a second input shaft, the right end of the box body is provided with an output shaft, a driving gear of the first input shaft is meshed with a driving gear of the second input shaft, a driving gear of the second input shaft and a driven gear of the right-end output shaft are in transmission through a plurality of gears, the number of the gears is odd, and the output shaft is provided with a spline shaft.

Based on the technical scheme, assuming that the input power is in the forward rotation direction, when the input power is butted with the first input shaft, the first input shaft rotates forward and drives the second input shaft to rotate reversely (because a driving gear of the first input shaft is meshed with a driving gear of the second input shaft), and an output shaft is driven to rotate reversely after transmission of odd gears; if the input power is butted with the second input shaft, the driving gear of the second input shaft is driven by the odd gears and then the output shaft rotates forwards; therefore, in actual use, two working states can be realized only by selecting different shafts, the structure is simple, the switching is convenient and flexible, and the used gearbox is unique and does not need a forward and reverse rotating gearbox.

Furthermore, the box body is in an inclined shape, a window is arranged on the upper surface of the box body, and a cover plate is arranged on the window. Usually, the rear rotary tillage or stubble cleaning shafts are in contact with the ground, the side box needs to be designed into an inclined direction, and the window is convenient for observing the state of the internal intermediate gear, so that the maintenance is convenient.

Furthermore, the first input shaft, the second input shaft driving gear and the driven gear of the output shaft are arranged in the box body, one side of the box body is fixed through a large blank cap, and the other side of the box body is fixed through a flange cap.

Furthermore, the big blank cap and the flange cover are fixed on the side of the box body through bolts.

Furthermore, a plurality of transition blank caps are arranged on the box body between the second input shaft and the output shaft.

The technical scheme can obtain the following beneficial effects:

the utility model has simple structure and low manufacturing cost, realizes that one gear box reaches two working states (positive rotation or reverse rotation), and the switching between the two working states is convenient and flexible; the number of odd gears is selected according to the length of the box body.

Detailed Description

The invention will be further explained with reference to the drawings:

as shown in fig. 1-2, a dual-purpose side case of double shafts comprises a case body 1, a first input shaft 3 and a second input shaft 2 are arranged at the left end of the case body 1, an output shaft 5 is arranged at the right end of the case body, a driving gear of the first input shaft is meshed with a driving gear of the second input shaft, the two driving gears are arranged in the case body and fixed through a big blank cap 9 and a flange cap 6, wherein the big blank cap 9 and the flange cap 6 are fixed at two sides of the case body through bolts, a driven gear of the same right-end output shaft is arranged at the right end of the side case and also fixed through the big blank cap 9 and the flange cap 6, the driving gear of the second input shaft is meshed with the driven gear of the right-end output shaft through 3 intermediate gears in sequence, the intermediate gears are installed on the case body through rotating shafts, and the output shafts adopt spline shafts, the spline shafts are butted with a rotary tillage shaft or a stubble cleaning shaft. The box is the slope shape, and the box upper surface is equipped with the window, is equipped with apron 8 on the window, still is equipped with on the box and filters stifle 7.

Example (b):

assuming that the power output by the gearbox is in the forward rotation direction, after the output shaft of the gearbox is connected with the first input shaft, because the driving gear of the first input shaft is meshed with the driving gear of the second input shaft, the first input shaft rotates forward and simultaneously drives the second input shaft to rotate reversely, and further after the transmission shaft is meshed with the second input shaft through 3 intermediate gears, the output shaft rotates reversely; if the output shaft of the gearbox is connected with the second input shaft, the output shaft rotates forwards after the driving gear of the second input shaft is meshed through 3 intermediate gears; therefore, in actual use, two working states can be realized only by selecting different shafts, the structure is simple, the switching is convenient and flexible, and the used gearbox is unique and does not need a forward and reverse rotating gearbox.

Wherein the both sides of every intermediate gear all are equipped with filtration stifle 7, the maintenance in intermediate gear and later stage of easy to assemble.
