Abstract

The invention discloses a hidden traction device, and belongs to agricultural machinery. A left ball head hooked draw bar and a right ball head hooked draw bar are installed on the left end portion and the right end portion of the front end of a longitudinal hollow traction beam frame through the respective hooking and clamping cooperation of draw bar bases and draw bar hinge pins and can be integrally inserted into the longitudinal hollow traction beam frame in a hidden mode, a buffering traction hook assembly is assembled on the front end portion of the left ball head hooked draw bar through a lower hinge pin and is locked on the left ball head hooked draw bar through a positioning pin, and the left ball head hooked draw bar and the right ball head hooked draw bar are hinged through an upper hinge pin. The hidden traction device is novel and reasonable in structural design, the left ball head hooked draw bar and the right ball head hooked draw bar can be integrally inserted into the longitudinal hollow traction beam frame in the hidden mode when a large wide agricultural machine works in the farmland, the transport operation traction state and the field operation hidden state can be switched over and adjusted conveniently and fast, and the hidden traction device is good in stability, and neat, compact and attractive in appearance.

Description

Hidden type draw-gear

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, in order to facilitate highway transportation and the transfer tasks place of large-scale wide cut operation agricultural tool, the large-scale wide cut operation farm machinery of part are provided with the side draw-gear that is specifically designed to highway transportation and conversion process place on its frame end, realize the longitudinal tractive walking manner of facility, improved the performance of passing through of facility conevying efficiency and facility.But, because such draw-gear is packed on frame sidepiece, and it is not quick detachable and hiding, when facility farm work, draw-gear has occupied larger space position, not only make frame center of gravity produce skew, facility degree parallel to the ground reduces, and affects operation quality, and the increase of complete machine lateral dimension, pass through poor performance.

Summary of the invention

Object of the present invention is exactly the problem existing for above-mentioned prior art, in conjunction with in agricultural production operation, large-scale wide cut farm machinery transportation and transfer place being needed, design provides a kind of hidden type draw-gear of new construction, reaches the convenient object of using, guaranteeing facility transaction capabilities.

The object of the present invention is achieved like this: on the left and right end of longitudinal 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, by draw bar bearing pin, coordinate left and right side bulb hook draw bar is fitted in respectively on the traction pole socket of left and right end with the dogging of left side bulb hook draw bar and right side bulb hook draw bar, and described left and right side bulb hook draw bar integral body can be hidden and is inserted in longitudinal hollow traction roof beam structure; On the bulb hook draw bar leading section of left side, by lower bearing pin, be equipped with buffering draw hook assembly, alignment pin is inserted on buffering draw hook assembly and left side bulb hook draw bar, will cushion draw hook assembly and lock on the bulb hook draw bar of left side; Upper pin inserting, on left side bulb hook draw bar and right side bulb hook draw bar leading section, is hinged left side bulb hook draw bar and right side bulb hook draw bar, so far forms hidden type draw-gear.

Structural design of the present invention is new reasonable, the hidden type state conversion of hauling operation traction state and farm work is easy to adjust quick, when large-scale wide cut farm machinery farm work, left and right side bulb hook draw bar of the present invention can wholely insert and be hidden in longitudinal hollow traction roof beam structure, reduced the horizontal fabric width of farm machinery, guarantee 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 type draw-gear, on longitudinal hollow traction roof beam structure 4 left and right ends of front end, symmetry is fixedly mounted with

traction pole socket

7,5 insertings of draw bar bearing pin are arranged on traction pole socket 7, by draw bar bearing pin 5, coordinate left and right side bulb

hook draw bar

3,8 is fitted in respectively on the traction pole socket 7 of left and right end with the dogging of left side bulb hook draw bar 3 and right side bulb hook draw bar 8, and described left and right side bulb

hook draw bar

3,8 integral body can be hidden and are inserted in longitudinal hollow traction roof beam structure 4; On bulb hook draw bar 3 leading sections of left side, by the equipped buffering draw hook of lower bearing pin 6 assembly 1, 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; Upper pin 2 insertings, on left side bulb hook draw bar 3 and right side bulb hook draw bar 8 leading sections, are hinged left side bulb hook draw bar 3 and right side bulb hook draw bar 8.The structure of described buffering draw hook assembly 1 is: on traction shank 101, can be set with slidingly back and forth cushion collar 104, on traction shank 101, the place, forward and backward position that is positioned at cushion collar 104 joins respectively prelocalization seat board 102, rear location seat board 106 admittedly, compression spring 103 and rear compression spring 105 before being set with on traction shank 101, described front compression spring 103 and rear compression spring 105 lay respectively at position between cushion collar 104 front end faces and prelocalization seat board 102 and cushion collar 104 rear end faces and rear location seat board 106; On cushion collar 104 outside portions, be fixedly mounted with the location-plate 107 with pin-and-hole.

During use, hidden type draw-gear 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 transportation of large-scale wide cut farm machinery or shift place operation.When farm machinery carry out farm work, pull up upper pin 2 and alignment pin 9, left and right side bulb
