Description

Synchronous gear box of plastic film residue collector

Technical Field

The utility model belongs to the technical field of agricultural machine's design and manufacturing, especially relate to a synchronous gear case of plastic film residue collector.

Background

In the operation process of the existing residual film recycling machine, the most important step is how to pick up the residual film from the ground and to separate the residual film easily. The more extensive mode of picking up of current application is the drum-type, and the characteristics of drum-type pickup mechanism are that the structure is fairly simple, generally wholly is cylindricly, is fixed with a plurality of film-picking teeth on it, through the rotation of whole stack shell, film-picking tooth buries and picks up the plastic film residue. In order to avoid the winding of the recovered residual film on the take-up drum, holes for the projecting/retracting of the film picking teeth are generally designed on the outer side of the take-up drum. In order to realize the extension and retraction of the film picking teeth, a currently common method is to install a track of a cam structure on the side surface of the pickup roller, and drive the rotation angle of the film picking teeth through a connecting rod to realize the extension and retraction of the film picking teeth. The structure of the mode is complex, the track and the connecting rod are always in contact and have friction, and the track and the connecting rod are easily abraded. In order to solve the problem of stretching of the film picking teeth and the picking roller peripheral shell, simplify the structure and reduce the abrasion of parts, the synchronous gear box of the residual film recycling machine is required to be designed, the stretching of the film picking teeth in the picking roller shell can be completed, the consistent rotating direction is ensured, the structure is simple, the abrasion is small, and the service life is long.

SUMMERY OF THE UTILITY MODEL

1. Technical problem to be solved

To the problem that exists among the prior art, the utility model aims to provide a synchronous gear case of plastic film residue collector, it can realize, can accomplish the flexible and guarantee the direction of rotation unanimity of film picking tooth in picking up the cylinder casing, simple structure, and wearing and tearing are little, long service life.

2. Technical scheme

In order to solve the problem, the utility model adopts the following technical proposal.

A synchronous gear box of a residual film recycling machine comprises a gear box shell, a first synchronous gear, a second synchronous gear, an idler wheel, a connecting shaft sleeve and the like. The first synchronous gear is fixed on the connecting shaft, and one end of the connecting shaft is rotatably connected with the gearbox shell. The second synchronous gear is fixedly connected to the connecting shaft sleeve, and the connecting shaft sleeve is rotatably connected with the gearbox shell. The idle gear is rotationally connected to the gear box shell, and the first synchronous gear and the second synchronous gear are the same in size and are meshed with the idle gear simultaneously. The outer wall of the connecting shaft sleeve is connected with a shell, the connecting shaft is located inside the connecting shaft sleeve, and the rotating center of the connecting shaft sleeve are not in the same center. The connecting shaft is used for connecting the film-picking teeth of the pickup roller, the connecting shaft sleeve is used for connecting the shell of the pickup roller, the film-picking teeth can stretch and contract on the circumference relative to the shell when rotating because the rotating centers of the film-picking teeth and the shell are not at the same center, and meanwhile, the rotating angular velocities of the film-picking teeth and the shell are consistent all the time because the sizes of the first synchronous gear and the second synchronous gear are the same, so that the film-picking teeth can stretch and retract in the holes of the same shell all the time, and the condition that the film-picking teeth collide with the shell is avoided.

3. Advantageous effects

Compared with the prior art, the utility model has the advantages of:

(1) Both rotation centers of this scheme connecting axle and connecting sleeve are not at same center, and it will have the relative casing to flip the membrane tooth to stretch out and draw back on the circumference when rotating, and simultaneously because of synchronous gear one is the same with two sizes of synchronous gear, flip the membrane tooth and the angular velocity of rotation of casing is unanimous all the time, has guaranteed that flip the membrane tooth can stretch out and draw back and can not appear flip the condition emergence of membrane tooth and casing collision all the time in the downthehole on same casing, and wearing and tearing are little like this, long service life.
