Abstract
The utility model relates to a guide box for a boat tractor and belongs to the technical field of parts of the boat tractor. The guide box is composed of a shell body, an input chain wheel, an output chain wheel, an input shaft, an output shaft, an input gear, an output gear and an operation lever, wherein the output shaft and the input shaft are arranged in the shell body from top to bottom, the output gear is movably arranged on the output shaft in the shell body, the input gear is fixedly arranged on the input shaft in the shell body, and the operation lever is movably arranged on the output gear. According to the guide box, the output gear is driven by the operation lever to slide on the output shaft and be meshed with the input gear so that the purposes of transmission and stop of motive power can be achieved, and therefore the guide box solves the problems that in an existing boat tractor, a two-grade belt tension wheel type separation and reunion device is used so that in working processes, the phenomenon of slipping occurs easily, and a rotary tillage device is coaxial with the traveling wheels and is the same as traveling wheels in speed so that tillage efficiency is low. The guide box remarkably improves the tillage efficiency and tillage quality.
Description
Technical field
The utility model relates to a kind of guide case for boat tractor, belongs to boat tractor parts technical field.
Background technology
Along with developing rapidly of agricultural machinery, the at present agricultural production in the whole nation has all realized mechanization basically, for the production of agricultural machinery in the middle of, boat tractor is exactly widely agricultural machinery of a kind of scope of application.Boat tractor is as China's innovation and creation of the seventies in last century, so far still widely use at rice producing areas of southern China take " floating principle " although as the core technology of feature, but its technological progress and slow, power transmission is the Combination leather belt transmission, mechanical efficiency is low, especially the rotary cultivator attachment of the selected extension in hull rear end is by the wheeled arrangement of clutch of two-stage belt tension, the phenomenon of skidding not only appears in the course of the work easily, and because of rotary cultivator attachment and road wheel coaxial synchronized, cause farming efficient lower, the problem that cultivating quality is relatively poor.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, high efficiency, quality good, pass through the wheeled arrangement of clutch of two-stage belt tension with the rotary cultivator attachment that solves existing boat tractor, the phenomenon of skidding not only appears in the course of the work easily, and because of rotary cultivator attachment and road wheel coaxial synchronized, cause farming efficient lower, the guide case that is used for boat tractor of cultivating quality poor.
The technical solution of the utility model is:
A kind of guide case for boat tractor, it is made of housing, input sprocket, output chain gear, power shaft, output shaft, input gear, output gear and action bars, it is characterized in that: being up and down in the housing, shape is equipped with output shaft and power shaft by bearing respectively, one end of output shaft and power shaft extends to respectively the housing outer end, is fixed with respectively output chain gear and input sprocket on the output shaft of housing outer end and the power shaft; Be movably installed with output gear on the output shaft in the housing, be fixed with input gear on the power shaft in the housing, described output shaft is splined shaft, is movably installed with action bars on the output gear.
The beneficial effects of the utility model are:
The guide case that should be used for boat tractor is simple in structure, driving output gear by action bars slides at output shaft, itself and input gear are meshed, and then the purpose that can reach power transmission and stop, and input gear is the gear of different speed ratios with output gear, avoided existing boat tractor by the wheeled arrangement of clutch of two-stage belt tension, the phenomenon of skidding not only appears in the course of the work easily, and rotary cultivator attachment is coaxial synchronized with road wheel, cause the lower problem of farming efficient, improved significantly farming efficient and cultivating quality.
Description of drawings
Among the figure: 1, housing, 2, input sprocket, 3, output chain gear, 4, power shaft, 5, output shaft, 6, input gear, 7, output gear, 8, action bars, 9, bearing.
Embodiment
The guide case that should be used for boat tractor is made of housing 1, input sprocket 2, output chain gear 3, power shaft 4, output shaft 5, input gear 6, output gear 7 and action bars 8.Being up and down in the housing 1, shape is equipped with output shaft 5 and power shaft 4 by bearing 9 respectively, output shaft 5 is splined shaft, one end of output shaft 5 and power shaft 4 extends to respectively housing 1 outer end, is fixed with respectively output chain gear 3 and input sprocket 2 on the output shaft 5 of housing 1 outer end and the power shaft 4; Be movably installed with output gear 7 on the output shaft 5 in the housing 1, be movably installed with action bars 8 on the output gear 7.Be fixed with input gear 6 on the power shaft 4 in the housing 1.
In the utility model when work, drive output gears 7 by action bars 8 and slide at output shaft 5, and make it with input gear 6 engagements or separate, the purpose that can reach power transmission and stop, and then the rotary cultivator attachment that stern is installed rotates or stops.Input gear 6 of the present utility model is the gear of different speed ratios with output gear 7, thereby avoided existing boat tractor by the wheeled arrangement of clutch of two-stage belt tension, the phenomenon of skidding appears in the course of the work easily, and rotary cultivator attachment is coaxial synchronized with road wheel, cause the low relatively poor problem of cultivating quality of farming efficient, improved significantly farming efficient and cultivating quality.Being specially adapted to the boat tractor power transmission uses.
