​Extended Steering Axle for Corn Harvester

Technical Field

The utility model relates to components of harvesting machinery, and more particularly to an extended steering axle for a corn harvester.

Background Art

In recent years, the planting area of crops such as corn has continued to expand. However, harvesting is still mainly carried out manually, resulting in low production efficiency. With social development and technological progress, mechanical harvesting will inevitably replace manual operations.

Due to differences in crop planting patterns, the terrain and field conditions encountered by harvesters also vary. Therefore, agricultural machinery is required to operate smoothly; otherwise, the harvesting quality will be affected. Designing a steering axle structure that operates stably, has a large load-bearing capacity, and can be adjusted in length according to terrain conditions or corn row spacing will greatly improve harvesting quality and enable harvesters to perform more efficient crop harvesting operations.

Summary of the Utility Model

The purpose of the utility model is to provide an extended steering axle for a corn harvester, which has a reasonable structure and allows effective adjustment of the axle length according to different corn row spacings.

Technical Solution

The utility model adopts the following technical solution:

An extended steering axle for a corn harvester comprises a steering axle frame, steering arms, a steering tie rod, wheel assemblies, and a steering hydraulic cylinder.

Steering arms are rotatably connected to both ends of the steering axle frame.

The steering arms are connected to wheel assemblies arranged on both sides of the axle frame.

A cylinder mounting plate is provided at the middle of the steering axle frame.

The steering axle frame includes:

A main axle sleeve (axle tube),

A first telescopic tube and a second telescopic tube extendable at both ends of the axle sleeve.

The first and second tubes can slide axially relative to the inner wall of the axle sleeve. Two locking devices are correspondingly arranged on the outer wall of the axle sleeve to fix the first and second tubes.

The first and second tubes are respectively connected to the steering arms at both ends of the axle frame.

One end of the double-piston rod of the steering hydraulic cylinder is hinged to the cylinder mounting plate, and the other end is hinged to the middle of the steering arm.

Both ends of the steering tie rod are fixed to mounting holes at the ends of the steering arms, and the steering tie rod is a telescopic rod.

Beneficial Effects

The extended steering axle for a corn harvester provided by the utility model allows both the steering tie rod and the axle frame to be adjustable in length. This enables proper matching of dimensions to accommodate different corn row spacings.

At the same time, the smoothness and stability of the vehicle are improved, thereby enhancing operational safety.

Detailed Description

As shown in Figure 1, the extended steering axle for a corn harvester includes a steering axle frame (1), steering arms (2), a steering tie rod (3), wheel assemblies (4), and a steering hydraulic cylinder (5).

Steering arms (2) are rotatably connected to both ends of the steering axle frame (1).

The steering arms (2) are connected to wheel assemblies (4) arranged on both sides of the axle frame (1).

A cylinder mounting plate (6) is arranged at the center of the steering axle frame (1).

The steering axle frame (1) includes:

An axle sleeve (11),

A first tube (12) and a second tube (13) that are telescopically arranged at both ends of the axle sleeve (11).

The first tube (12) and the second tube (13) can slide axially along the inner wall of the axle sleeve (11). Two locking devices (14), preferably tightening bolts, are arranged on the outer wall of the axle sleeve (11) to fix the first and second tubes.

The first tube (12) and the second tube (13) are respectively connected to the steering arms (2) at both ends of the axle frame (1).

One end of the double-piston rod of the steering hydraulic cylinder (5) is hinged to the cylinder mounting plate (6), and the other end is hinged to the middle of the steering arm (2).

The steering hydraulic cylinder (5) has:

A cylinder length of 450 mm

A maximum stroke of both piston rods of up to 173 mm

Both ends of the steering tie rod (3) are fixed to mounting holes at the ends of the steering arms (2).

The steering tie rod (3) is a telescopic rod.

Except for the technical features described above, all other features are well known to those skilled in the art.
