Description

The double-draught device of bow-type tractor

Technical field

The utility model is related to technical field of agricultural machinery, especially a kind of double-draught device of bow-type tractor.

Background technology

Bow-type tractor is the self-propelled motor machine for drawing and driving Work machine to complete every mobile operation. The draw-gear of current bow-type tractor, which includes, is separately mounted to propons, front frame and Rear frame on back axle, before being mounted in Draw bar is housed, the two ends of draw bar pass through bearing pin and traction seat, Rear frame respectively between the traction seat and Rear frame on vehicle frame It is hinged.The draw-gear of this bow-type tractor has the following disadvantages in use：Compartment can be produced in the process of moving Traction connecting portion, which is often produced, during raw swing, particularly load-carrying swings up and down, and causes the connecting portion of draw bar two ends easily to break Split and deform；The less stable that front frame is connected with Rear frame, in emergency brake or turning, is easily caused before tractor Portion's phenomenon that individually rollover or rear portion are individually turned on one's side.

Utility model content

Problem to be solved in the utility model is to provide a kind of double-draught device of bow-type tractor, can solve to carry Traction connecting portion, which is produced, during weight is swung up and down, and the connecting portion of draw bar two ends is easily broken off and deforms, and less stable is asked Topic.

In order to solve the above problems, the technical solution adopted in the utility model is：Double tractions of this bow-type tractor Device, includes and is equipped with front frame, Rear frame and draw bar, the front frame on traction seat, the traction seat by traction Pin is hinged with two draw bars set up and down, the Rear frame equipped at least with one piece of connecting plate, is led described in two Draw bar through the connecting plate, spacing bayonet lock is housed in the rear end of the draw bar.

In the double-draught device technical scheme of above-mentioned bow-type tractor, more specifically technical scheme can also be：It is described Traction seat includes two supports set up and down, and the support has two pieces of fixed plates set up and down, and two pieces described solid Fagging is connected between fixed board, the fixed plate is provided with draw pin openings.

Further, the front end of the draw bar is equipped with the axle sleeve coordinated with the towing pin and is sleeved on the draw bar On rest pad, the axle sleeve and the rest pad are located between two pieces of fixed plates of the support.

Further, multiple steering cylinders are hingedly connected between the front frame and the Rear frame.

By adopting the above-described technical solution, the utility model has the advantages that compared with prior art：

1st, the utility model is hinged with two draw bars set up and down, Rear frame on traction seat by towing pin Equipped at least with one piece of connecting plate, two draw bars pass through connecting plate, and spacing bayonet lock is housed in the rear end of draw bar；It is greatly lowered Swinging up and down for connecting portion generation is drawn during load-carrying, it is to avoid the connecting portion of draw bar two ends occurs being broken and deformed, and adds The stability that front frame is connected with Rear frame, in emergency brake or turning, it is to avoid occur tractor front portion individually rollover or The phenomenon that rear portion is individually turned on one's side, it is safe.

2nd, traction seat includes two supports set up and down, and support has two pieces of fixed plates set up and down, two pieces Fagging is connected between fixed plate, fixed plate is provided with the middle of draw pin openings, two pieces of fixed plates of draw bar insertion support and led to Cross traction pin connection, draw bar and traction seat stable connection.

3rd, the front end of draw bar is equipped with the axle sleeve coordinated with towing pin and the rest pad being sleeved on draw bar, axle sleeve and branch Supporting block is located between two pieces of fixed plates of support；Further prevent draw bar from swinging up and down, it is to avoid support is deformed.

4th, multiple steering cylinders are hingedly connected between front frame and Rear frame；Turned using the driving of multiple steering cylinders To turning to bow-type tractor steady.
