Description
Technical field
The utility model belongs to farm machinery technical field, specifically, and the particularly belt tension wheel mounting structure on microtilling machine.
Background technique
Microtilling machine is the agriculture apparatus of New Times, have lightweight, volume is little, the feature such as simple in structure, be widely used in the nonirrigated farmland, paddy field, orchard on Plain, mountain area, hills etc., mix corresponding facility and can draw water, generate electricity, spray the operations such as medicine, spray, also can draw towed vehicle and carry out short-distance transport.Microtilling machine has stronger flexibility, can freely travel in field, user-friendly and deposit, and has saved the worry that large-scale farm machinery cannot enter mountain area field, for peasant has saved the plenty of time in busy farming season.
Idle wheel is the vitals on microtilling machine, is responsible for giving belt stable tension force, avoids belt slack to skid and loses gearing.Existing microtilling machine Idle wheel mounting structure is complicated, assembly manipulation difficulty, and not only cost is high, and Idle wheel is safeguarded and is changed inconvenience, and Idle wheel maintainability is poor.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of microtilling machine belt tension wheel mounting structure of simple in structure, easy accessibility.
The technical solution of the utility model is as follows: a kind of microtilling machine belt tension wheel mounting structure, comprise tension arms (1) and Idle wheel (2), described tension arms (1) is " Z " shape, the first perpendicular section (1a) by top, the second perpendicular section (1b) of below and middle tilting section (1c) form, lower end in the second perpendicular section (1b) has mounting hole (1d), in the first perpendicular section (1a), be equipped with bolt (3), the middle part of this bolt (3) is by bearing (4) supporting Idle wheel (2), described bearing (4) is positioned at the middle part of Idle wheel (2) inner chamber, one end of this bearing (4) is spacing by the step surface on Idle wheel (2) inwall, the other end of bearing (4) is spacing by the spring collar (5) of the interior setting-in of Idle wheel (2), described spring collar (5) is by nut (6) locking of the upper suit of bolt (3), between the first perpendicular section (1a) of described bearing (4) and tension arms (1), be provided with spacer (7), the plate face of one end of spacer (7) and the first perpendicular section (1a) fits, the other end of spacer (7) stretches in Idle wheel (2), and fit with the inner ring of bearing (4).
Adopt above technological scheme, tension arms is " Z " shape, and moulding is simple, is easy to processing and fabricating, and cost is low, and structural strength is reliable, is difficult for deforming or damaging.Idle wheel is supported on the bolt that tension arms upper end wears by bearing, and assembly manipulation is very convenient; Bearing is positioned at the middle part of Idle wheel inner chamber, and the equal limited location structure in two ends, and Idle wheel rotates flexibly like this, beat can not occur.Spring collar and nut are demountable structure, and dismounting is convenient, are conducive to maintenance and the replacing of Idle wheel.Between the first perpendicular section of bearing and tension arms, be provided with spacer, compact structure, can effectively reduce volume on the one hand; On the other hand, spacer separates tension arms and Idle wheel, has effectively avoided Idle wheel and tension arms to interfere.
For when being convenient to selection, reducing production costs, guarantee the structural strength of tension arms, prevent that tension arms from deforming, the strip-shaped steel plate impact briquetting that described tension arms (1) is 3mm by thickness.
In order further to optimize structure, the described first perpendicular section (1a) parallels with the second perpendicular section (1b), between the first perpendicular section (1a) and tilting section (1c), has the angle of 135 °.
The position eccentric at described tilting section (1c) middle part offers positioning hole (1e), and positioning hole, for clutch extension spring provides mounting point, is conducive to clutch extension spring and articulates, thereby guaranteed that Idle wheel oppresses on drivign belt all the time.
Beneficial effect: the utility model is simple in structure, assembly manipulation is convenient, and cost of production is low, and Idle wheel maintenance and replacing are convenient, and Idle wheel maintainability is good, has the features such as reasonable in design, transformation is easy, reforming cost is low.
