Power expands case
Technical field
The utility model relates to soil cultivating machine field, and specifically a kind of power expands case.
Background technology
In prior art, in mountain region and knob, rotary cultivator is generally used to carry out soil cultivation operation, rotary tillage carries out cutting mainly by the rotation of cutter to soil and completes relevant farming operation, existing usual employing miniature gasoline engine or the hand steered step that small diesel engine is power plough formula agricultural tillage machinery series, this small-size rotary tiller is normally only provided with one or two tool driving shaft, therefore, on existing rotary cultivator, typically being also provided only with one to two rotary blades carries out operation, if the quantity of rotary cultivator tool cutter drive shaft to be increased, the structural complexity of rotary cultivator will be greatly increased, make rotary cultivator volume bigger, it is unfavorable in mountain region and knob operation.
Therefore, for solving problem above, needing a kind of power to expand case, this power is expanded case and is had multiple output shaft, each output shaft all can be installed rotary tillage cutter, thus be greatly increased the working width of rotary cultivator, improve its farming efficiency.
Utility model content
In view of this, the purpose of this utility model is to overcome defect of the prior art, it is provided that a kind of power expands case, this power is expanded case and is had multiple output shaft, rotary tillage cutter all can be installed on each output shaft, thus be greatly increased the working width of rotary cultivator, improve its farming efficiency.
Power of the present utility model expands case, the power accepting power input shaft including casing, power input shaft and at least two the power output shaft outputed power;
Further, described power output shaft is arranged in pairs and the output speed of every pair of power output shaft is identical and it is contrary to turn to;
Further, described power output shaft is two, and the respectively first power output shaft and the second power output shaft;Described first power output shaft arranges with power input shaft coaxial integrated and transversely runs through described casing;
Further, be set up in parallel by even number between adjacent power output shaft and engage successively travelling gear transmission power;
Further, first support shaft parallel with the first power output shaft and the second support shaft it are fixed with in described casing;Described travelling gear is four, and is respectively the gear I that coordinates with the first pto and gear II that the first support shaft is rotatably assorted and the gear III that the second support shaft is rotatably assorted and the gear IV that coordinates with the second pto;
Further, the one-body molded bearing block that is provided with of described wall box, it is provided with the bearing for supporting power output shaft in described bearing block.
The beneficial effects of the utility model are: power of the present utility model is expanded case and is provided with the power output shaft of multiple acceptable power input shaft power, power output shaft can be in transmission connection in the tool driving shaft of rotary cultivator, on multiple power output shafts, rotary blade is installed, so that the tool driving shaft of rotary cultivator can simultaneously drive multiple rotary blade and rotate, increase the farming width of rotary cultivator, improve its farming efficiency.
Accompanying drawing explanation
With embodiment, the utility model is further described below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as shown in the figure, the power of the present embodiment expands case, including casing, power that power input shaft 1 and at least two accept power input shaft 1 power output shaft 6 outputed power, power of the present utility model is expanded case and is provided with the power output shaft 6 of multiple acceptable power input shaft 1 power, power output shaft 6 can be in transmission connection in the tool driving shaft of rotary cultivator, on multiple power output shafts 6, rotary blade is installed, so that the tool driving shaft of rotary cultivator can simultaneously drive multiple rotary blade and rotate, increase the farming width of rotary cultivator, improve its farming efficiency.
In the present embodiment, described power output shaft 6 is arranged in pairs and the output speed of every pair of power output shaft 6 is identical and turns to contrary;Every pair of power output shaft 6 is connected with the rotary blade that blade is oppositely oriented respectively, cancels out each other about the reaction force that the paired rotary blade being arranged on power output shaft 6 produces in the course of work of burying, it is ensured that without swinging about machine.
In the present embodiment, described power output shaft 6 is two, and the respectively first power output shaft 6 and the second power output shaft 6;Described first power output shaft 6 arranges with power input shaft 1 coaxial integrated and transversely runs through described casing, therefore the power of the present embodiment is expanded case and can be used the tool driving shaft of rotary cultivator as power input shaft 1 and one of them power output shaft 6, thus simplifies the structure of this expansion case.
In the present embodiment, the travelling gear that is set up in parallel by even number between adjacent power output shaft 6 and engages successively transmission power, the size of each travelling gear, the number of teeth are the most identical, thus ensure that the rotation of each power output shaft 6 is identical and rotation direction is contrary.
In the present embodiment, in described casing, it is fixed with first support shaft parallel with the first power output shaft 6 and the second support shaft;Described travelling gear is four, and is respectively the gear I8 that coordinates with the first power output shaft 6 transmission and gear II7 that the first support shaft is rotatably assorted and the gear III2 that the second support shaft is rotatably assorted and the gear IV5 that coordinates with the second power output shaft 6 transmission.
In the present embodiment, the one-body molded bearing block 3 that is provided with of described wall box, it is provided with the bearing for supporting power output shaft 6 in described bearing block 3, bearing block 3 is shaped in wall box and can be effectively improved the structural compactness of this expansion case.
Finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent, without deviating from objective and the scope of technical solutions of the utility model, it all should be contained in the middle of right of the present utility model.
