Description
Technical Field
The utility model relates to an axle, a triplex row cotton picker steering axle specifically says so.
Background
The company mainly produces the steering axle of the harvesting machine, the steering axle is born below 3 tons, along with the development of the economic integration of the world, the mechanical industries of various countries in the world continuously improve the new technology of the steering axle, and meanwhile, the steering axle is continuously connected with the international orbit, and large-scale harvesting machines in foreign countries are introduced for research and development so as to meet the industrialized development requirements of China.
The existing company develops a steering axle of a cotton picker for a three-row cotton picker in a certain host factory, mainly because the current axle is difficult to meet the requirement, the maximum bearing tonnage of the steering axle of the cotton picker is 12 tons, and in order to meet the product requirement of the host factory, the structure of the steering axle designed by the company meets the normal requirement according to the requirements of a steering angle, an camber angle, a spoke distance, a tire mounting center distance, a height difference of a frame, the bearing capacity and the like provided by the host factory, and the product is successfully developed to provide competitiveness for the company on a large-tonnage harvesting machine.
Disclosure of Invention
In order to solve the problems, the utility model aims to provide a three-row cotton picker steering axle.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a triplex row cotton picker steering axle, including the seam pontic and rotate the knuckle assembly that sets up at seam pontic both ends respectively, the seam pontic is formed through the welding of horizontal steel sheet by two W-shaped steel sheets, and the both ends level of seam pontic is fixed with the oblique support cylinder down, the knuckle assembly rotates and sets up in the support cylinder, the swing arm of knuckle assembly is the rhombus, and the center is the center of rotation, the same end of swing arm of both sides is rotated through the tie rod assembly respectively and is connected, the swing arm other end of both sides then is provided with whole steering angle device respectively, and two whole steering angle devices are rotated through connecting rod and the fixed hydro-cylinder both ends in the outside middle part of seam pontic respectively and are connected.
The overall design concept is as follows: because of bearing load is great, the crossbeam that adopts horseshoe tube or rectangular tube structure can't satisfy and bears the requirement, and present crossbeam structure adopts the steel sheet to splice and weld, and the steel sheet thickness of two W shapes is 16mm, and middle reinforcing plate (being horizontal steel sheet) is 16mm, and both ends are the circular arc structure, can effectively play the cushioning effect in the use, have avoided stress concentration phenomenon, can effectually avoid the fracture inefficacy to take place.
In order to improve the steering synchronism, the oil cylinder with a one-way double-output structure is adopted, and meanwhile, a limiting structure is added, so that the steering stability of the whole vehicle is improved.
The swing arm and the oil cylinder are connected in order to effectively prevent the specification of the connecting hole from being invalid and increase uniformly.
The welding structure scheme of the steering knuckle and the steering vertical shaft is designed, and the structure adopts a combined welding tool for one-time welding, so that the performance parameters of the welding process are ensured, and the space arrangement requirement and the assembly connection technical requirement of the whole vehicle assembly steering axle are met.
Drawings
The present invention will now be further described with reference to the accompanying drawings.
Fig. 1 is a schematic view of the structure of the present invention;
fig. 2 is a schematic top view of the present invention.
Detailed Description
As shown in figure 1 and figure 2, the three-row cotton picker steering axle comprises a welded axle body 1 and steering knuckle assemblies 2 which are respectively and rotatably arranged at two ends of the welded axle body 1, wherein the welded axle body 1 is formed by welding two W-shaped steel plates through horizontal steel plates, two ends of the welded axle body 1 are horizontal and are fixedly provided with support cylinders which face obliquely downwards, the steering knuckle assemblies 2 are rotatably arranged in the support cylinders, swing arms 3 of the steering knuckle assemblies 2 are rhombic, the centers of the swing arms are rotation centers, the same ends of the swing arms 3 at two sides are respectively and rotatably connected through steering pull rod assemblies 4, the other ends of the swing arms 3 at two sides are respectively provided with steering angle adjusting devices 5, the two steering angle adjusting devices 5 are respectively and rotatably connected with two ends of oil cylinders 6 which are fixed at the middle part of the outer part of the welded axle body 1 through connecting rods, and a central shaft 7 which is used for fixedly connecting the W-shaped steel plates is arranged at the middle part of the.
The swing arm 3 is connected to the harvester, in the running process, the oil cylinder is stretched by rotating the steering wheel, the stretching of the oil cylinder drives the swing arm 3 and the steering knuckle assembly 2 to rotate, and simultaneously drives the steering pull rod assembly 4 to enable the steering knuckle assembly 2 on the other side to synchronously rotate.
The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
Claims (2)
1. A three-row cotton picker steering axle is characterized in that: including the seam pontic with rotate the knuckle assembly that sets up at seam pontic both ends respectively, the seam pontic is formed through the welding of horizontal steel sheet by two W-shaped steel sheets, and the both ends level of seam pontic is fixed with the oblique support cylinder down, the knuckle assembly rotates and sets up in supporting a section of thick bamboo, the swing arm of knuckle assembly is the rhombus, and the center is the center of rotation, the same end of swing arm of both sides is rotated through the tie rod assembly respectively and is connected, the swing arm other end of both sides then is provided with whole steering angle device respectively, and two whole steering angle devices are rotated through connecting rod and the fixed hydro-cylinder both ends in the outside middle part of seam pontic respectively and are connected.
