Description

Paddy field unilateral ridge building machine ridge building assembly horizontal slewing mechanism

technical field

The invention belongs to agricultural machinery, and mainly relates to a ridge-building machine tool for unilaterally building paddy field ridges.

Background technique

The ridge building machine is a paddy field machine used to replace manual ridge building. It has the characteristics of high ridge building efficiency, solid and beautiful ridges, etc. However, the existing unilateral paddy field ridge-building machines are all tractor-hung traction operations. When the tractor drives to the field, there will be a distance between the tractor and the ridge-building machine that cannot be built. Manpower is still required to complete this part of the field ridge construction. The operation will not only make the consistency of the field ridge fail to meet the requirements, affect the solidity of the field ridge, and cannot realize the complete mechanized operation of paddy field ridge construction, but also has high labor intensity, waste of human resources, high operating cost, and low operating efficiency. In order to solve the above problems, the applicant has developed a paddy field single-side ridge-building machine with a reversible single-side rotary tillage and ridge-building operation assembly. The assembly completes the overturn on the vertical plane. When overturning, the whole machine needs to be greatly raised to its height position, which is inconvenient to use, low in operating efficiency and poor in safety.

The purpose of good safety and high work efficiency.

The purpose of the present invention is achieved in this way: a horizontal slewing mechanism of a paddy field unilateral ridge building machine ridge building assembly includes a traction suspension frame assembly and a unilateral rotary tillage ridge construction operation assembly, and the traction suspension frame The gearbox assembly is fixed on the middle part of the rear side of the assembly, and the ground wheel support frame is rotatably hinged and installed on the lower side of the gearbox assembly on the horizontal plane. On the right end, located in front of the ground wheel support frame, an electromagnetic automatic locking device is symmetrically equipped, and a two-way hydraulic cylinder and a swing rod are swingably installed on the upper rear side of the traction suspension frame assembly. The fork seat connects the two-way hydraulic cylinder with the swing rod hinge, and the movable and rotatable mounting bracket is fixed on the outer part of the ground wheel support frame on the long hole of the swing rod. Ridge operation assembly, the upper side of the single-side rotary tillage and ridge construction operation assembly is connected to the bracket by inserting and hanging, and the front side of the single-side rotary tillage and ridge construction operation assembly is locked by the electromagnetic automatic locking device. Connect and lock fit; the electromagnetic control switch is installed on the traction suspension frame assembly.

The invention adopts the rotary steering structure of the single-side rotary tillage and ridge building operation assembly on the horizontal plane, which greatly reduces the lifting height of the whole machine during the rotary operation, and has the advantages of novel and reasonable structure, simple and convenient use and operation, and high rotary operation efficiency , safe and reliable.

Detailed ways

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. A horizontal slewing mechanism of a paddy field unilateral ridge building machine ridge building assembly includes a traction suspension frame assembly 1 and a single side rotary tillage ridge construction operation assembly 3, on the middle part of the rear side of the traction suspension frame assembly 1 The gearbox assembly 7 is fixed, and the ground wheel support frame 10 is rotatably hingedly installed on the lower side of the gearbox assembly 7 on the horizontal plane, and on the left and right ends of the rear side of the traction suspension frame assembly 1. 1. An electromagnetic automatic locking device 8 is symmetrically equipped at the front part of the ground wheel support frame 10, and a two-way hydraulic cylinder 2 and a swing rod 4 are swingably hingedly installed on the upper rear side of the traction suspension frame assembly 1, The hinged fork seat 5 hinges the two-way hydraulic cylinder 2 with the swing rod 4, and the movable and rotatable mounting bracket 6 on the elongated hole of the swing rod 4 is mounted on the outer side of the ground wheel support frame 10. The single-side rotary tillage and ridge building operation assembly 3 is fixedly installed on the top, and the upper side of the single-side rotary tillage and ridge construction operation assembly 3 is connected to the bracket 6 by inserting and hanging, and the single-side rotary tillage and ridge building operation assembly 3. The front side part is clamped and locked with the electromagnetic automatic locking device 8; the electromagnetic control switch 9 is installed on the traction suspension frame assembly 1.
