Description
Technical field
The utility model relates to a kind of tractor-ploughing farm machinery that is used for the paddy field, particularly a kind of tractor-ploughing equipment that relates to the arable land, paddy field.
Background technology
In order to alleviate the labour intensity of peasant's field work, various agricultural machinery equipments are used and are given birth to, patent documentation as China Patent No. 200420018105.1 discloses the dual-purpose boat tractor of a kind of floods and droughts, comprises hull, deflecting roller, frame, power set, transmission device, gearbox, action bars, farming roller.China Patent No. 200620052624.9 patent texts that the inventor has obtained right power disclose boat tractor rotary tillage cutter, and China Patent No. is that 200620050358.6 patent documentation has then been announced a kind of boat tractor.Boat tractor commonly used generally comprises hull, deflecting roller, frame, power set, transmission device, gearbox, manipulation device, rotary tillage wheel and road wheel.Propelling along with agricultural mechanization; particularly after the soil appropriate scale of operation; people have higher requirement to the efficient of tractor-ploughing; traditional boat tractor rotary tillage wheel is coaxial with speed with road wheel; its rotary tillage efficient and effect are limited by the speed of travel; therefore the rotating speed of rotary tillage wheel is low, causes efficient lower, and effect reduces.The problem that also has rotary blade to be twined when in addition, present boat tractor uses in the paddy field that weeds are arranged by weeds.
The utility model content
At present boat tractor because rotary tillage wheel and road wheel are coaxial with fast the problems referred to above of being brought, the purpose of this utility model is to provide a kind of novel rotary tillage formula boat tractor, the rotating speed of this boat tractor rotary tillage wheel is not subjected to the influence of road wheel rotating speed, and the rotating speed that therefore can improve the rotary tillage wheel as required is to improve rotary tillage efficient and rotary tillage effect.
The utility model adopts following technical scheme: a kind of rotary tillage formula boat tractor, comprise hull, deflecting roller, frame, power set, transmission device, gearbox, manipulation device, the rotary tillage wheel, road wheel, it is characterized in that: described road wheel is installed on the described output shaft of gear-box to be driven by output shaft of gear-box, be mounted with first driven gear on the output shaft of gear-box, also has second driven gear and/or the 3rd driven gear difference kink in the first driven gear both sides on described output shaft, described rotary tillage is taken turns also kink and is driven on described output shaft and by described second driven gear and/or the 3rd driven gear, and described first driven gear and second driven gear and the 3rd driven gear are driven by power shaft by the intermediate drive gear on the jackshaft in the gearbox respectively.
The rotary tillage wheel can adopt the disclosed mode of 200620052624.9 Chinese patents or existing other frame mode.In order further to solve the problem that weeds are twined on the rotary tillage wheel, described rotary tillage wheel comprises axle sleeve and the rotary blade that is installed on the axle sleeve, axle sleeve constitutes double-decker by coaxial inner core and urceolus, described inner core and urceolus are connected and fixed by tool rest, described rotary blade is installed on the described tool rest, and fixedly fixtures such as the bolt of rotary blade or rivet are positioned at the urceolus inboard.Owing to adopt double-deck axle sleeve structure, though inner diameter of steel flue is constant because the existence of urceolus makes the axle sleeve external diameter increase, and fixture to be positioned at urceolus inboard not exposed, be unfavorable for the winding of weeds, can solve weeds preferably and twine problem.
The sleeve end of described rotary tillage wheel is fixedlyed connected with the rotary tillage wheel coupling sleeve of kink on described output shaft by bolt, described rotary tillage wheel coupling sleeve is fixing to be driven rotation synchronously by driven gear with respect to one in described second driven gear and the 3rd driven gear, rotary tillage wheel coupling sleeve is with cylindrical shape with the outside of the axle sleeve point of attachment of rotary tillage wheel and becomes the weeding outer ring, make this outside, position also be capped like this, enlarge the junction external diameter, form smooth outer surface, be unfavorable for the winding of weeds.
Since rotary tillage wheel kink on output shaft and an end fix, swing with respect to output shaft when avoiding the suspended wall end stressed, described rotary tillage wheel inner core is equipped with support set away from gearbox one end with exporting between the moving axis.Described support set can adopt nylon jacket, and anti-wear performance is good.Cost is lower with respect to bearing is installed, and structure is also simple.
Described rotary tillage wheel is gone up the rotary blade of installing and is at least 1 group, and every group has at least more than 2., more satisfactory is that 2-6 group rotary blade is arranged respectively on every group of rotary tillage wheel, every group is that 2-4 is on the axle sleeve that radially is evenly distributed on the rotary tillage wheel, to improve rotary tillage effect and efficient.
This rotary tillage formula boat tractor of the present utility model, compared with prior art its beneficial effect is:
(1) road wheel is installed on the output shaft and is driven by the first driven gear teeth, and rotary tillage wheel to be kink driven by second driven gear or the 3rd driven gear of same kink on output shaft on the output shaft, utilize the idler gear of different gear ratio on the jackshaft, realized road wheel and rotary tillage wheel different rotating speeds, therefore can avoid both with the low problem of rotary tillage efficient that speed is brought, can improve rotary tillage efficient and effect.
(2) the rotary tillage axle sleeve structure of employing two layered cylinder, outer because of enlarged-diameter, play the effect of anti-grass.
