Description

a conveying device

technical field

The invention belongs to the field of environmental protection machinery, in particular to a conveying device.

Background technique

In the field of environmental protection, when dealing with sewage or kitchen waste, it is often necessary to rotate the reactor carrying sewage or dirt. The traditional transmission device is a motor-controlled driving gear. The driving gear is connected to the circular shaft at the end of the reactor through a chain. The driven gear is connected to the driven gear (as shown in Figure 3). This device is more convenient during operation, but when it needs to stop working, it is necessary to stop the motor slowly. If the motor is stopped quickly, the reactor will continue to rotate due to inertia. As a result, the chain is affected to transmit force to the driving gear and the motor, causing damage to the driving gear and even the motor. More seriously, if the inertia of the reactor is too large and the driving motor and the driving gear cannot keep up with its rotation, it will hinder its rotation. The damage of the reactor often causes hundreds of thousands of machines to be scrapped.

SUMMARY OF THE INVENTION

Purpose of the invention: The purpose of the present invention is to provide a conveying device in view of the deficiencies of the prior art.

Technical solution: In order to achieve the above-mentioned purpose of the invention, the present invention is implemented as follows: a transmission device includes a driving gear controlled by a motor, and the driving gear is connected with a driven gear connected to the circular shaft at the end of the reactor through a chain, and the said There is a No. 1 driven gear with a diameter larger than it just above the driving gear; the No. 1 driven gear is fixed on a bracket, the bracket is a C-shaped structure, and both sides of the bracket are provided with rollers, and a pair of parallel The top surface of the bracket is also a C-shaped structure; the bottom of the motor is fixed on the support plate, and the bottom of the support plate has a pair of parallel No. 1 rollers, and the No. 1 rollers are in a pair of parallel The motor slides on the No. 2 track; the motor is arranged in the cavity of the bracket.

Wherein, the first track and the second track are parallel to each other.

The top of the bracket is provided with a pair of triangular fixed frames, and a rotating shaft is arranged between the fixed frames. The rotating shaft passes through the through hole in the middle of the No. 1 driven gear. Limited fixed block.

Wherein, the surface of the rotating shaft has external threads, and the limiting and fixing block is a nut with matching internal threads.

The specific working principle of the invention is as follows: when the motor needs to be stopped, the motor runs in the direction close to the reactor, and the support runs in the opposite direction to ensure that the moving speed of the support and the motor is the same. When the support moves until the chain is completely located between the driven gear and a When it is between the numbered gears, the motor can be turned off, preventing the damage caused by the emergency stop of the motor.

Beneficial effects: The present invention is scientifically designed and utilizes the characteristic that the diameter of the No. 1 driven gear is larger than that of the driving gear to realize the natural switching of the chain from the driving gear to the No. 1 driven gear, so that the motor and the driving gear are protected to the maximum extent.

Detailed ways

Example 1:

A transmission device as shown in FIG. 1 includes a driving gear 2 controlled by a motor 1. The driving gear 2 is connected with a driven gear 5 connected to the circular shaft at the end of the reactor 4 through a chain 3. There is a No. 1 driven gear 6 with a diameter larger than it; the No. 1 driven gear 6 is fixed on a bracket 7, the bracket 7 is a C-shaped structure, and both sides of the bracket 7 have rollers 8, and in a pair of Slide on the parallel No. 1 track 9, the top surface of the bracket 7 is also a C-shaped structure; the bottom of the motor 1 is fixed on the support plate 10, and the bottom of the support plate 10 has a pair of parallel No. 1 rollers 11. The No. 1 roller 11 slides on a pair of parallel No. 2 rails 12 ; the motor 1 is arranged in the cavity of the bracket 7 , and the No. 1 rail 9 and the No. 2 rail 12 are parallel to each other.

Example 2:

Referring to Embodiment 1, the bracket and the No. 1 driven gear have a fixed structure: the top of the bracket 7 is provided with a pair of triangular fixing frames 13, and a rotating shaft 14 is built between the fixing frames 13, and the rotating shaft 14 runs through the No. 1 driven gear. The through hole in the middle of the driving gear 6, the two sides of the No. 1 driven gear on the rotating shaft 14 are provided with limit fixing blocks 15, the surface of the rotating shaft 14 has external threads, and the limiting fixing blocks 14 are matched with it. Internally threaded nut.

During the specific implementation of the present invention, it is necessary to ensure that: the height of the triangular fixing frame is sufficient to prevent the chain from contacting the support when moving; the roller and the No. 1 roller should be fixed during the normal operation of the equipment, such as setting on the No. 1 track and the No. 2 track. Blocks, etc., prevent the displacement of the motor and the bracket in use; the upper bracket corresponding to the driving wheel has a cavity, so that the chain has no chain and no intersection when the driving wheel and the No. 1 driven gear are shifted.
