[0041] Working principle: The present invention drives the toothed disc transmission mechanism 3 to operate through the motor drive mechanism 2, and then drives the main body mechanism 1 of the garbage cleaning machine to perform the garbage cleaning operation. The motor protection mechanism 4 is responsible for protecting the motor during the operation of the motor to prevent damage to the motor due to abnormal conditions such as the garbage cleaning machine getting stuck, overloaded, and overheated. When the motor protection mechanism 4 is stuck and cannot rotate in the garbage cleaning machine, and it is not discovered and stopped in the first time, the two small long bolts break under the force of the garbage cleaning machine's motor, and the motor of the garbage cleaning machine drives the protective device disk to rotate and disengages from the garbage cleaning machine sprocket 21, ultimately achieving the purpose of protecting the motor of the garbage cleaning machine. The controller 5, as the core of the entire system, is responsible for receiving signals from various sensors, and controlling the motor drive mechanism 2, the toothed disc transmission mechanism 3 and the motor protection mechanism 4 according to the preset logic;

[0045] The motor drive mechanism 2 includes: a raised platform 14, the raised platform 14 is fixedly installed on the right top of the rectangular frame 6, a drive motor 15 is fixedly installed on the top of the raised platform 14 along the left and right directions, the right output shaft end of the drive motor 15 is fixedly connected to the coupling 16, and a motor protection cover 17 is fixedly installed on the outside of the drive motor 15. A vertical shaft output hole 18 is opened on the right side wall of the motor protection cover 17, and the output shaft of the drive motor 15 passes through the shaft output hole 18 horizontally.

[0046] The working principle and beneficial effects of the above technical solution are as follows: Working Principle: The main mechanism 1 of the cleaning machine drives the main shaft 8 through the operation of the drive motor 15 and the gear transmission mechanism 3. The main gear 9 on the main shaft 8 drives the secondary gear 11 to rotate via the chain 12, which in turn drives the secondary shaft 10 and the cleaning grille 13 to perform the cleaning operation. The cleaning scraper 7 is used to scrape away dirt attached to the surface of the cleaning grille 13. The motor protection cover 17 protects the drive motor from external collision damage and also provides a soundproofing effect.

[0047] Beneficial Effects: This technical solution achieves effective removal of dirt and improves cleaning efficiency through the chain drive and the design of the cleaning grid 13. At the same time, the design of the cleaning scraper 7 further enhances the cleaning effect and ensures the cleanliness of the cleaning machine.

[0048] Example 3

[0049] On the basis of Example 2, Figure 1-Figure 3As shown, the geared disc transmission mechanism 3 includes: a bearing support 19, a vertical bearing support 19 is fixedly installed on the top right side of the rectangular frame 6, a rotating shaft 20 is rotatably provided on the top of the bearing support 19 along the left and right directions, the rotating shaft 20 rotates through the bearing support 19, the left input end of the rotating shaft 20 is fixedly connected to the right end of the coupling 16, the rotating shaft 20 is located on the right side of the bearing support 19 and is rotatably connected to a sprocket 21, the right end of the main shaft 8 is fixedly installed with a sprocket 2, and the sprocket 121 is meshed with the sprocket 2 through a transmission chain.

[0051] The working principle and beneficial effects of the above technical solution are as follows: Working principle: The gear transmission mechanism 3 transmits the power of the drive motor 15 to the main rotating shaft 8 through the rotating shaft 20, thereby driving the main mechanism 1 of the garbage cleaning machine to work. During specific operation, the drive motor 15 runs through the coupling 16 to drive the rotating shaft 20 to rotate, and the rotating shaft 20 drives the protection device disk and the sprocket 21 to rotate synchronously. The motor protection mechanism 4 fixes the protection device disk on the rotating shaft 20 through the flat key and the long bolt. When the chain 12 and the garbage cleaning grille 13 of the garbage cleaning machine are stuck, or the motor is overloaded, overheated, or other abnormal conditions occur, the drive motor 15 uses the same torque to break the small long bolts. The long bolt torque is designed to be less than the maximum bearing torque of the drive motor 2. The motor protection device disk can quickly respond and disengage from the sprocket 21, and protect the drive motor 15 from damage. The sliding separation mechanism is used to quickly separate the protection device disk and the rotating shaft 20 when needed, to prevent the separated motor protection device disk and the broken long bolts from splashing out, so as to facilitate maintenance or replacement.

[0052] Beneficial Effects: This technical solution, through the design of the geared disc transmission mechanism 3 and the motor protection mechanism 4, achieves effective protection and transmission of the motor, improving the reliability and safety of the equipment. At the same time, the design of the sliding separation mechanism further enhances the maintainability and flexibility of the equipment.

[0055] The bottom right end of the internal thread slider 33 is fixedly connected to a slide bar 34 along the left and right directions. The slide bar 34 slides left and right and passes through the vertical plate 2 30. The right end of the slide bar 34 is fixedly installed with a vertical electric lifting rod 35. The bottom movable end of the electric lifting rod 35 is fixedly installed with a concave clamp 36. A strong magnetic block 37 is fixedly installed in the center of the concave clamp 36. A distance sensor 38 is fixedly installed on the outside of the concave clamp 36. When the concave clamp 36 slides to the right, it provides a separation force for the protective device disk and the rotating shaft 26.

[0056] The working principle and beneficial effects of the above technical solution are:

[0057] Working Principle: When the long bolt breaks, the sliding separation mechanism 28 begins to operate. The sliding motor 32 drives the lead screw 31 to rotate, which in turn drives the internally threaded slider 33 and slide bar 34 to move axially along the lead screw 31. When slide bar 34 reaches a certain position, the electric lift rod 35 extends, driving the concave clamp 36 and strong magnetic block 37 toward the protective device disk. The strong magnetic block 37 attracts the protective device disk, preventing it from being thrown out by the rotating shaft 1.

[0058] Beneficial Effects: This technical solution, through the design of the sliding separation mechanism 28, achieves rapid and safe separation of the protective device disc, improving the maintainability and ease of operation of the equipment. Furthermore, the design of the strong magnetic block 37 further enhances the separation effect, ensuring the stability and reliability of the separation process.

[0072] a judgment processing unit, configured to compare and judge whether the cumulative torque evaluation value between the protection device plate 26 and the long bolt 27 during the detection time period is greater than a torque evaluation threshold;

[0073] The first calculation unit calculates based on the following formula 1:

[0074] in: The output energy coefficient between the protective device plate 26 and the long bolt 27 during testing is: is the torque coefficient between the protective device disk 26 and the long bolt 27 during detection, G1 is the torsional stiffness between the protective device disk 26 and the long bolt 27, G2 is the tightening stiffness between the protective device disk 26 and the long bolt 27, ln is a logarithmic function, e is a natural constant with a value of 2.72, T1 is the temperature value of the protective device disk 26 detected by the temperature detection unit 1 during the detection period t-t0, T2 is the temperature value of the long bolt 27 detected by the temperature detection unit 2 during the detection period t-t0, t is the detection end time recorded by the timer, and t o is the initial detection time recorded by the timer, T max is the maximum operating temperature of the protection device disk 26 detected by the temperature detection unit 1, T min The temperature detection unit 1 detects the minimum operating temperature of the protection device disk 26.

[0076] Where: T i is the cumulative torque evaluation value between the protection device plate 26 and the long bolt 27 during the i-th detection period, T i-1 is the cumulative torque evaluation value between the protection device plate 26 and the long bolt 27 during the i-1th detection period, T y is the theoretical maximum torque between the protective device plate 26 and the long bolt 27, π is the value of pi, which is 3.14, T W T0 is the average surface temperature of the driving motor 15 detected by the temperature detection unit 3, and T0 is the ambient temperature detected by the temperature detection unit 4;

[0077] The judgment processing unit operates. If the cumulative torque evaluation value between the protective device plate 26 and the long bolt 27 during the i-th detection period is less than or equal to the torque evaluation threshold, the alarm does not respond. If the cumulative torque evaluation value between the protective device plate 26 and the long bolt 27 during the i-th detection period is greater than the torque evaluation threshold, the control unit controls the alarm to sound an alarm and stops the drive motor 15, notifying maintenance personnel to perform repairs.

[0078] The working principle and beneficial effects of the above technical solution are:

[0079] Working Principle: The intelligent detection and protection module uses speed sensor 1, temperature detection unit 1, temperature detection unit 2, temperature detection unit 3, and temperature detection unit 4 to detect parameters such as the output shaft speed of drive motor 15, the temperature of the protective device disk 26, the temperature of the long bolt 27, the surface temperature of drive motor 15, and the ambient temperature. A first calculation unit calculates the output energy coefficient and torque coefficient between the protective device disk 26 and the long bolt 27 during the detection period based on the data from temperature detection units 1 and 2 and the time recorded by the timer. A second calculation unit calculates the cumulative torque evaluation value between the protective device disk 26 and the long bolt 27 during the i-th detection period based on the calculation results of the first calculation unit and the data from speed sensor 1 and temperature detection unit 4. The judgment processing unit compares the cumulative torque evaluation value with a torque evaluation threshold. When the cumulative torque evaluation value exceeds the torque evaluation threshold, the control unit controls the alarm to sound an alarm and stops drive motor 15.

[0080] Beneficial Effects: This technical solution, through the design of an intelligent detection and protection module, enables real-time monitoring and assessment of the operating status of the garbage cleaning machine's motor. This allows for the timely detection and resolution of abnormalities, preventing equipment damage and safety accidents caused by motor failures.
