Description

The release type power transmission device that the driving wheel set cooperates with the steel wire rope

technical field

The utility model relates to a power transmission device used for an orchard transporter, in particular to a release type power transmission device in which a driving wheel pair is matched with a steel wire rope.

Background technique

In view of the characteristics that fruit trees such as citrus, apple and pear are mainly planted on hills and slopes, a variety of orchard transporters dedicated to hills have been proposed at home and abroad, such as the 7YGD-35 self-propelled single-track orchard driven by sprocket sprockets. Conveyors and 7YGDQ-50 remote-controlled traction single-track conveyors driven by winches, 7YGWQ-50 remote-controlled traction trackless conveyors and traction double-track orchard conveyors, etc. Although the structures of the transporters are different, the power transmission device as its core component determines the performance of the transporter to a large extent. For example, the power transmission device that adopts sprocket sprocket matching has the problems of high processing difficulty and high cost, and is only suitable for slope terrain below 35 degrees. There is a power transmission device driven by a winch: 1. The length of the wire rope wound on the winch is generally about 100 meters, and the distance of the transportation line is short, which is difficult to meet the actual needs of large-scale orchards; 2. The drum shaft is easy to bend and twist, which makes the wire rope easy to 3. The cumulative winding of the wire rope on the drum not only makes the wire rope messy and disorderly, causes the wire rope to be worn, but also seriously affects the release of the wire rope.

Detailed ways

Further illustrate the utility model below in conjunction with accompanying drawing and embodiment.

Embodiment: The utility model comprises two support frames 1 each provided with two bearing seats 11, both ends are provided with bearings 6 and are respectively connected to the drive shaft 2 and the driven shaft 3 of the support frame 1, driven by the first drive wheel 41 and the driving wheel pair 4 and steel wire rope 5 that the second driving wheel 42 constitutes. The bearing seat 11 is fixed on the support frame 1 by bolts 12; the two ends of the driving shaft 2 and the two ends of the driven shaft 3 are positioned and connected to the bearing 6 through the sleeve 7, and the driving shaft 2 and the driven shaft 3 are They are laid parallel to each other and fixed on the support frame 1 through two bearing blocks 11; the bearing 6 is located in the bearing block 11; the first driving wheel 41 and the second driving wheel 42 are respectively connected to the drive shaft 2 and the The driven shaft 3 is connected and is respectively provided with five first annular communication grooves 411 and five second annular communication grooves 421; the first annular communication grooves 411 and the second annular communication grooves 421 are parallel to each other and staggered one way Setting; the steel wire rope 5 is respectively wound and connected with the first annular communication groove 411 and the second annular communication groove 421 in a manner of winding "8", specifically: the steel wire rope 5 passes through the first annular communication groove 411 on the first driving wheel 41 Enter the first groove of the second drive wheel 42 by crossing into the first groove of the second annular communication groove 421 on the second drive wheel 42 in an "8" shape, and then by the second annular communication groove 421 on the second drive wheel 42 The first groove returns to the second groove of the first annular communication groove 411 on the first drive wheel 41 around the "8" shape, and is wound and connected around the "8" shape in turn until the steel wire rope 5 passes from the second drive wheel 42 The fifth groove of the second annular communication groove 421 passes through.

When working, the drive shaft 2 is connected to the power source, that is, the power is input from one end of the drive shaft 2, and the drive shaft 2 drives the first drive wheel 41 to rotate, and the steel wire rope 5 under tension at both ends cooperates with the first annular communication groove 411 to generate friction , and then drive the second drive wheel 42 on the driven shaft 3 to rotate, and complete the input of the steel wire rope 5 from one end and output from the other end, so that the power transmission of the steel wire rope 5 is released. The friction force between the steel wire rope 5 and the driving wheel pair 4 can be adjusted by adjusting the number of wire rope 5 and the first annular communication groove 411 and the second annular communication groove 421 in the shape of an "8" cross-coordinated winding, so as to avoid the friction caused by long-term operation.
