AI Technical Summary
The existing garbage sorting bin motor mechanism is prone to burn out when used at high frequency, and the door opening angle is small, which can easily lead to the motor breaking the steel wire and interfering and stopping.
The crank rocker mechanism is used to output power through the reducer motor, limit the range of the swing rod action, and a proximity switch sensor is installed under the motor mounting bracket to detect the opening state to prevent abnormal jamming.
It effectively avoids the motor burning due to abnormal stopping, reduces the range of moving parts, protects the garbage sorting bin and structural parts, and ensures that the motor works continuously for a long time in complex environments.

Abstract
Description
Technical Field
[0001] The utility model relates to a motor mechanism of a garbage classification box and belongs to the technical field of garbage classification boxes. Background Art
[0002] At present, the market basically uses electric push rods as the power source for opening the door panels of garbage bins, such as the Chinese utility model patent CN201922320926.X, a garbage classification box. The electric push rod has a simple structure and a small size. The application scenarios are relatively small spaces. The motor power cannot be increased, which limits it from being opened frequently and cannot be overloaded, otherwise it will burn out the motor and damage the internal motor drive board. When applied to the delivery port of the garbage bin, during peak hours in the morning and evening, the work is too frequent, the motor heats up, and failures occur frequently. When the delivery port is manually pushed, the motor load is too large and it will also be damaged. Therefore, its application is for items that are not often moved, and it can be guaranteed that it is not used in abnormal scenarios.
[0003] Based on this professional and technical field, technicians have developed Figure 3 The technical solution of directly using a reduction motor as a power driving source can effectively solve the technical drawbacks of the aforementioned push rod solution, but other technical problems still remain during its use:
[0004] 1. The door opening angle is too small. Changing the motor installation position cannot change the connecting rod's rotation area and cannot improve this problem.
[0005] 2. When the proximity switch is damaged, the motor will break the steel wire, and the connecting rod of the reduction motor will hit the mounting carrier, causing interference and jamming, thereby burning the motor and damaging the equipment. Utility Model Content
[0006] In order to solve the above problems existing in the prior art, the utility model provides a motor mechanism for a garbage classification box.
[0007] The technical solution of the utility model is as follows:
[0008] A motor mechanism for a garbage sorting box comprises a mounting bracket carrier installed on the top of an inner cavity of the garbage sorting box, a motor mounting bracket being arranged on the mounting bracket carrier, a rocker arm being rotatably mounted on the front end of the motor mounting bracket, a reduction motor being installed on the rear end of the motor mounting bracket, a crank rod being connected to the output end of the reduction motor, a connecting rod being connected between the crank rod and the rocker arm, the end of the rocker arm being connected to the inner wall of a garbage outlet baffle through a soft connecting steel wire, the upper end of the garbage outlet baffle being rotatably mounted on the top of the inner cavity of the garbage sorting box through a hinge, and being located in front of the mounting bracket carrier.
[0009] Wherein, the reduction motor is a worm reduction motor.
[0010] Wherein, a proximity switch sensor is installed below the front end of the motor mounting bracket.
[0011] The utility model has the following beneficial effects:
[0012] The utility model discloses a motor mechanism for a garbage sorting box, which outputs the power source of the motor by adopting a crank rocker mechanism, so that the rocker arm swings downward to the left and right, and the rotation range of the crank rod is lower than that of the mounting bracket carrier. The overall scheme reduces the possible movement range of the movable parts in the event of a disengagement failure, and even in the event that the soft connecting wire breaks, it can prevent the movable parts from interfering with the garbage sorting box or other structural parts and getting stuck. It can protect the garbage sorting box and other structural parts when a failure is out of control, and at the same time can prevent the reduction motor from burning out due to abnormal sticking.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0019] See also Figure 1 and Figure 2, a garbage classification box motor mechanism, comprising a mounting bracket carrier 1 installed on the top of the inner cavity of the garbage classification box, a motor mounting bracket 2 is arranged on the mounting bracket carrier 1, a swing rod 3 is rotatably installed at the front end of the motor mounting bracket 2, a reduction motor 4 is installed at the rear end of the motor mounting bracket 2, a crank rod 5 is connected to the output end of the reduction motor 4, a connecting rod 6 is connected between the crank rod 5 and the swing rod 3, the end of the swing rod 3 is connected to the inner wall of the garbage inlet baffle 8 through a soft connecting wire 7, the upper end of the garbage inlet baffle 8 is rotatably installed on the top of the inner cavity of the garbage classification box through a hinge 9, and is located in front of the mounting bracket carrier 1, wherein the motor mounting bracket 2, the crank rod 5, the connecting rod 6 and the swing rod 3 constitute a specific four-bar mechanism, namely a crank rocker mechanism, thereby limiting the swing rod 3 from swinging left and right downward, and the rotation range of the crank rod 5 is lower than that of the mounting bracket carrier 1. Compared with the original solution of directly adopting a reduction motor ( Figure 3 As shown in the figure, the possible movement range of the movable parts in the event of a separation failure is reduced. Even in the case that the soft connecting wire 7 is broken, the movable parts can be prevented from interfering with the garbage classification box or other structural parts and getting stuck. When the failure is out of control, the garbage classification box and other structural parts can be protected, and the reduction motor can be prevented from burning out due to abnormal sticking.

[0021] Furthermore, a proximity switch sensor 10 is installed below the front end of the motor mounting bracket 2 to detect whether the garbage inlet baffle 8 is fully opened and send an electrical signal to the controller to control the reduction motor 4 to stop moving.
