Abstract

Hidden traction device belongs to agricultural machinery; By drawing the installation left and right side bulb hook draw bar of pole socket and the cooperation of draw bar bearing pin difference hook card on longitudinal left and right end, hollow traction roof beam structure front end, described left and right side bulb hook draw bar entirety can be hidden and be inserted in longitudinal hollow traction roof beam structure, by lower bearing pin equipped buffering draw hook assembly on the bulb hook draw bar leading section of left side, buffering draw hook assembly locks by alignment pin on the bulb hook draw bar of left side, and left and right side bulb hook draw bar is hinged by upper pin; This apparatus structure is rationally novel in design, when large-scale wide cut farm machinery farm work, left and right side bulb hook draw bar overallly can insert and be hidden in longitudinal hollow traction roof beam structure, hauling operation traction state and farm work implicit type State Transferring fast easy to adjust, facility good stability, external form is neat, compact, attractive in appearance.

Description

Hidden traction device

Technical field

The invention belongs to agricultural machinery, relate generally to the draw-gear on a kind of large-scale agricultural tool.

Background technology

At present, the conveniently highway transportation of large-scale wide cut operation agricultural tool and transfer tasks place, the large-scale wide cut operation farm machinery of part are provided with the side draw-gear being specifically designed to highway transportation and conversion process place on its Frame end, achieve the longitudinal tractive walking manner of facility, what improve facility conevying efficiency and facility passes through performance.But, because such draw-gear is packed on frame sidepiece, and it is not quick detachable and hiding, when facility farm work, draw-gear occupies larger space position, not only make frame center of gravity produce skew, facility degree parallel to the ground reduces, and affects operation quality, and complete machine lateral dimension increases, and passes through poor performance.

Summary of the invention

Object of the present invention is exactly for above-mentioned prior art Problems existing, in conjunction with in agricultural production operation, large-scale wide cut farm machinery transport and transfer place are needed, design provides a kind of hidden traction device of new construction, reaches easy to use, ensures the object of facility transaction capabilities.

The object of the present invention is achieved like this: on longitudinal left and right end, hollow traction roof beam structure front end, symmetry is fixedly mounted with traction pole socket, the inserting of draw bar bearing pin is arranged on traction pole socket, coordinated by the hook card of draw bar bearing pin and left side bulb hook draw bar and right side bulb hook draw bar and left and right side bulb hook draw bar is fitted on the traction pole socket of left and right end respectively, and described left and right side bulb hook draw bar entirety can be hidden and is inserted in longitudinally in hollow traction roof beam structure; By lower bearing pin equipped buffering draw hook assembly on the bulb hook draw bar leading section of left side, alignment pin is inserted on buffering draw hook assembly and left side bulb hook draw bar, is locked by buffering draw hook assembly on the bulb hook draw bar of left side; Left side bulb hook draw bar and right side bulb hook draw bar, on left side bulb hook draw bar and right side bulb hook draw bar leading section, are hinged, so far form hidden traction device by upper pin inserting.

Novel in structural design of the present invention is reasonable, hauling operation traction state and farm work implicit type State Transferring fast easy to adjust, when large-scale wide cut farm machinery farm work, left and right side bulb hook draw bar of the present invention overallly can insert and be hidden in longitudinal hollow traction roof beam structure, reduce the horizontal fabric width of farm machinery, ensure facility job stability, facility external form is compact, neat, attractive in appearance.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present invention is described in detail.A kind of hidden traction device, on longitudinal left and right end, hollow traction roof beam structure 4 front end, symmetry is fixedly mounted with traction pole socket 7, draw bar bearing pin 5 inserting is arranged on traction pole socket 7, coordinated by the hook card of draw bar bearing pin 5 and left side bulb hook draw bar 3 and right side bulb hook draw bar 8 and left and right side bulb hook draw bar 3,8 is fitted on the traction pole socket 7 of left and right end respectively, and described left and right side bulb hook draw bar 3,8 entirety can be hidden and is inserted in longitudinally in hollow traction roof beam structure 4; By lower bearing pin 6 equipped buffering draw hook assembly 1 on bulb hook draw bar 3 leading section of left side, alignment pin 9 is inserted on buffering draw hook assembly 1 and left side bulb hook draw bar 3, will cushion draw hook assembly 1 and lock on left side bulb hook draw bar 3; Left side bulb hook draw bar 3 and right side bulb hook draw bar 8, on left side bulb hook draw bar 3 and right side bulb hook draw bar 8 leading section, are hinged by upper pin 2 inserting.The structure of described buffering draw hook assembly 1 is: can be set with cushion collar 104 slidingly back and forth on traction shank 101, on traction shank 101, the forward and backward position place that is positioned at cushion collar 104 joins prelocalization seat board 102, rear location seat board 106 respectively admittedly, compression spring 103 and rear compression spring 105 before suit on traction shank 101, described front compression spring 103 and rear compression spring 105 lay respectively at cushion collar 104 front end face and prelocalization seat board 102 and position between cushion collar 104 rear end face and rear location seat board 106; Cushion collar 104 outside portion is fixedly mounted with the location-plate 107 with pin-and-hole.

During use, hidden traction device of the present invention is fitted on a side end of large-scale wide cut farm machinery girder by longitudinal hollow traction roof beam structure 4, completes the longitudinal tractive transport of large-scale wide cut farm machinery or transfer place operation.When farm machinery carry out farm work, pull up upper pin 2 and alignment pin 9, hidden respectively by left and right side bulb hook draw bar 3,8 and be inserted in longitudinal hollow traction roof beam structure 4, buffering draw hook assembly 1 lock leans against on longitudinal hollow traction roof beam structure 4 leading section by recycling alignment pin 9.
