Abstract
The utility model relates to a tractor for farming, middle transmission boxes are connected with the outer end of the rear axle transmission semi axle shell of the two rear wheels and the upper end of the last transmission box. The middle transmission box consists of a transmission box shell, an upper drive gear wheel, a lower driven gear wheel and a middle transmission gear wheel, the upper end of the transmission box shell is connected with the rear axle transmission semi axle shell and the lower end is connected with the upper end of the last transmission box, the upper drive gear wheel, the middle transmission gear wheel and the lower driven gear wheel are arranged inside the transmission box shell, the upper drive gear wheel is connected with the transmission semi axle body inside the upper active gear wheel, the lower positive gear is connected with the active gear wheel body inside the last transmission box, the upper active gear wheel and the lower positive gear wheel articulates and are connected through the middle transmission gear wheel; correspondingly, the height of the steering post of the two front wheels is increased.
Description
The utility model relates to a kind of farm tractor.
Existing farm tractor, its body is lower apart from floor level, mostly is crack, lowland trac. greatly, then when carrying out field work, damages such as cotton, high grain, the contour bar crops of corn easily.
The purpose of this utility model is exactly in order to address the above problem, and a kind of high-arch tractor that can not damage high bar crops is provided.
Technical solution of the present utility model:
A kind of high-arch tractor, it includes tractor body, its two trailing wheel links to each other with the jackshaft of final driving device by its wheel disc respectively, jackshaft links to each other with tractor rear axle jackshaft housing by final transmission gearbox, a left side, right back bridge jackshaft housing integral body is connected the both sides of rear axle housing body, trac. two front-wheels are by its a preceding wheel disc and a left side, right two turn to semiaxis to link to each other, two turn to the turn to column of semiaxis by separately to link to each other with the farm tractor front axle crossbeam, the propons crossbeam waves axle by propons and links to each other with tractor body, it is characterized in that between the outer end of the back axle jackshaft housing of two trailing wheels and its final transmission gearbox upper end, all being connected to middle driving box, this middle driving box is by mechanism housing, last driving gear, following ring gear and intermediate drive gear constitute, the upper end of mechanism housing links to each other with back axle jackshaft housing, its lower end links to each other with the upper end of final transmission gearbox, last driving gear, intermediate drive gear and following ring gear are positioned at mechanism housing, on it driving gear directly with back axle jackshaft housing in whole linking to each other of jackshaft, ring gear links to each other with the driving gear in the final transmission gearbox is whole under it, and last driving gear and following ring gear are connected with a joggle togather by intermediate drive gear; Correspondingly, the column height that turns to of two front-wheels increases.
The utility model increases tractor body apart from ground-surface height, make the utility model be applicable to the farm work of high bar crops, and the intermediary and later stages operation of especially high bar crops does not almost have any damage, can effectively guarantee crop yield.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left side view of Fig. 1.
Fig. 3 is the structure for amplifying scheme drawing of the middle driving box in the utility model.
As Fig. 1,2,3, the utility model includes tractor body 1, its two trailing wheel 2 links to each other with the jackshaft 4 of final driving device by its wheel disc 3 respectively, jackshaft 4 links to each other with tractor rear axle jackshaft housing 6 by final transmission gearbox 5, a left side, right back bridge jackshaft housing 6 integral body are connected the both sides of rear axle housing body 7, trac. two front-wheels 8 are by its a preceding wheel disc and a left side, right two turn to semiaxis 9 to link to each other, two turn to the turn to column 10 of semiaxis 9 by separately to link to each other with farm tractor front axle crossbeam 11, propons crossbeam 11 waves axle by propons and links to each other with tractor body 1, characteristics of the present utility model are, between the outer end of the back axle jackshaft housing 6 of two trailing wheels 2 and its final transmission gearbox 5 upper ends, all be connected to middle driving box 12, this middle driving box 12 is by mechanism housing 13, last driving gear 14, following ring gear 15 and intermediate drive gear 16 constitute, the upper end of mechanism housing 13 links to each other with back axle jackshaft housing 6, its lower end links to each other with the upper end of final transmission gearbox 5, last driving gear 14, intermediate drive gear 16 and following ring gear 15 are positioned at mechanism housing 13, driving gear 14 jackshaft integral body direct and in the back axle jackshaft housing 6 link to each other on it, it is whole the linking to each other of driving gear in ring gear 15 and the final transmission gearbox 5 down, and last driving gear 14 is connected with a joggle togather by intermediate drive gear 16 with following ring gear 15; Correspondingly, the column 10 that turns to of two front-wheels 8 highly increases (height of its increase is identical with the height of the middle driving box 12 of trailing wheel 2).
The utility model is because the increase of trac. height; its front-wheel 8 turn to column 10 in front-wheel 8 travels, to run into little dead furrow the time fragile; so the utility model respectively is provided with a protection wheel 17 in the front portion of two front-wheels 8; two protection wheels 17 turn to column 18 to link to each other with protection crossbeam 19 by protection wheel separately; protection crossbeam 19 links to each other with tractor body 1 by its swivel pin; and protection wheel 17 nadirs are the 5-10 centimetre apart from ground-surface height; make two protection wheels 17 not contact under normal conditions with ground; by two front-wheels, 8 kiss the earth cruisings; and when running into little dead furrow; two protection wheels 17 enter at two front-wheels 8 and play the support protective effect when little dead furrow sinks, and guarantee that ditch did not have impact.
Because the height of tractor body 1 of the present utility model is raised, so can effectively reduce the scratch to high bar crops, effect is very good.
