High-clearance double-shaft wheel tractor

Abstract

The invention provides a high-clearance double-shaft wheel tractor which fills the blank that no applicable mechanisms are provided for later field management of dry crops. The high-clearance double-shaft wheel tractor can perform a plurality of middle and later working processes in a dry land, such as fertilizing and chemicals spraying, and has the characteristics of being high in mechanical efficiency, low in cost, advanced, applicable, practical, and high in social benefit and economic benefit. The high-clearance double-shaft wheel tractor is featured in the proposing of a high-clearance concept, the breakthroughs in technology of the tractor, as well as the core technologies of front and rear axis assemblies. The high-clearance double-shaft wheel tractor is characterized by comprising a (1) front wheel, a (2) front wheel shaft, a (3) front heightening upright arm, a (4) main rack, a (5) fixing connecting arm, a (6) chain wheel, a (7) rear heightening upright arm, a (8) brake assembly, a (9) rear wheel, a (10) lower chain wheel, a (11) driven shaft, a (12) chain, a (13) power driving shaft, a (14) gear box, a (15) front shaft and a (16) semi-axis outer sleeve. The high-clearance double-shaft wheel tractor has the features that the labor and material input can be decreased, and a management method is optimized; the efficiency of the materials and mechanisms can be improved, and the crop quality can be improved; the income is increased while the input is decreased; the pollution of an existing mode on the soil and underwater can be greatly reduced; extremely high social benefit and economic benefit are brought.

Description

(1) Technical field [0001] The invention relates to a new type of small double-axle wheeled tractor, and its technology involves a breakthrough in height-increasing technology. The ground gap between the half shaft and the ground exceeds 1200 mm, which can complete the mechanical work of various upland crops in the middle and late stages of field management. (2) Background technology [0002] The existing field management mode of upland crops is: in the middle stage of crop growth, when the plant height reaches more than 1 meter, there is no corresponding machine that can complete various field operations, which makes some material input unreasonable, but the existing machinery cannot complete it. One of the most important ones is the irrational use of chemical fertilizers. The utilization rate of chemical fertilizers in my country is only 30-40%. It can be seen that my country's chemical fertilizers and related industrial chains waste resources and pollute land and water. A...
