[0003] In the prior art, the power transmission system of a snow melting machine often lacks an effective fault detection mechanism. When the stirring blade is blocked by ice, traditional equipment may not be able to detect and respond in time, resulting in motor overload or even damage, increasing maintenance costs and downtime. Summary of the Utility Model

[0010] Optionally, it further includes an inner cover of the evaporator, and both the opto-coupler baffle and the opto-coupler switch are located inside the inner cover of the evaporator.

[0012] Optionally, a gland is installed on the bearing, a waterproof silica gel pad is installed on the inner wall of the gland, and the waterproof silica gel pad supports the side wall of the rotating shaft and the top of the inner cover of the evaporator.

[0013] Optionally, the opto-coupler switch is used to detect the stationary state of the opto-coupler baffle and send this information to the machine control system for taking corresponding measures.

[0014] Optionally, the opto-coupler baffle rotates synchronously with the rotating shaft and continuously blocks or passes through the light beam path of the opto-coupler switch under normal working conditions. Advantageous Effects

[0015] A drive mechanism for a snow melter according to the present utility model derives beneficial effects based on the content of independent claim 1.

[0016] 1. A drive mechanism for a snow melter according to the present utility model adopts a photoelectric detection system composed of an optocoupler baffle and an optocoupler switch, which can monitor the rotation state of the rotating shaft in real time. Once it detects that the rotating shaft stops rotating, it immediately sends a signal to the control system, enabling the machine to quickly take measures, such as stopping operation, giving an alarm or starting the thawing function, thereby avoiding motor overload and other potential risks.

[0017] 2. A drive mechanism for a snow melter according to the present utility model effectively protects the internal components from the external environment, especially preventing moisture intrusion, through the inner cover of the evaporator and the sealing structure (including bearings, gland covers and waterproof silicone gaskets).

[0023] It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined.

[0025] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0027] Referring to Figures 1-2 , an embodiment of a transmission mechanism of a snow melter provided by an embodiment of the present utility model includes:

[0028] A reduction motor 1 for providing power;

[0029] A rotating shaft 2 connected to the output end of the reduction motor 1 and transmitting power;

[0030] An optocoupler shutter 3 installed on the side wall of the rotating shaft 2;

[0031] The opto - coupling switch 4, in cooperation with the opto - coupling baffle 3, gives a signal to the machine control system when the rotating shaft 2 does not rotate, for indicating that the mixing blade is blocked by ice.

[0032] It should be noted that the reduction motor 1 is connected to the rotating shaft 2 through its output end, and transmits the generated power to subsequent working components, such as the mixing blade, etc., to realize the shedding of the sand - ice layer.

[0033] To ensure the safety and efficiency of the machine during operation, the transmission mechanism includes an opto - coupling baffle 3 and an opto - coupling switch 4. The opto - coupling baffle 3 is installed on the side wall of the rotating shaft 2 and rotates synchronously with the rotating shaft 2. The opto - coupling switch 4 is fixed and used in cooperation with the opto - coupling baffle 3. When the rotating shaft 2 stops rotating for any reason, such as the mixing blade being blocked by ice, the opto - coupling baffle 3 will no longer block the light beam path of the opto - coupling switch 4. At this time, the opto - coupling switch 4 will send a signal to the machine control system, prompting that corresponding measures need to be taken to solve the problem.

[0034] In some embodiments, an inner cover 8 of the evaporator is further included, and both the opto - coupling baffle 3 and the opto - coupling switch 4 are located inside the inner cover 8 of the evaporator.

[0035] It should be noted that in order to protect the internal components and optimize the space layout, all these components are located within the inner cover 8 of the evaporator. In particular, the opto - coupling baffle 3 and the opto - coupling switch 4 are also placed in this enclosed environment, ensuring that they can stably perform detection without being interfered by external factors.

[0036] In one example, a bearing 5 is installed on the outer wall of the rotating shaft 2, and the outer wall of the bearing 5 is connected to one end of the inner wall of the inner cover 8 of the evaporator. A gland 6 is installed on the bearing 5, a waterproof silica gel pad 7 is installed on the inner wall of the gland 6, and the waterproof silica gel pad 7 supports the side wall of the rotating shaft 2 and the top of the inner cover 8 of the evaporator.

[0037] It should be noted that considering that the rotating shaft 2 needs to rotate continuously while maintaining good mechanical properties, we set a bearing 5 on the outer wall of the rotating shaft 2 and connect it to one end of the inner cover 8 of the evaporator through the outer wall of the bearing 5. In addition, a gland 6 is provided above the bearing 5, and a waterproof silica gel pad 7 is located on the inner wall of the gland 6. This not only provides additional support for the rotating shaft 2, but also effectively prevents water from entering the inner cover 8 of the evaporator, maintaining the safety of the internal electronic components.

[0038] In some embodiments, the opto - coupling switch 4 is used to detect the stationary state of the opto - coupling baffle 3 and send this information to the machine control system so as to take corresponding measures. The opto - coupling baffle 3 rotates synchronously with the rotating shaft 2 and continuously blocks or passes through the light beam path of the opto - coupling switch 4 under normal working conditions.

[0039] It should be noted that the opto-coupler switch 4 is responsible for monitoring the state change of the opto-coupler baffle 3. Once a stationary situation is detected, which means the rotating shaft 2 may have encountered an obstacle or malfunction, it will immediately feed back this information to the machine control system, enabling the system to react in a timely manner, such as automatically stopping operation, issuing an alarm, or initiating other emergency procedures.

[0040] During normal operation, the opto-coupler baffle 3 rotates together with the rotating shaft 2, continuously blocking or passing through the light beam path of the opto-coupler switch 4, ensuring that the opto-coupler switch 4 can accurately determine whether the rotating shaft 2 is in a moving state. This design enables the opto-coupler switch 4 to provide a reliable monitoring function without affecting the normal operation of the machine.

[0041] In specific applications, when the snow melter starts working, the reduction motor 1 starts and provides power. Through the rotating shaft 2 connected to the output end of the reduction motor 1, the power is transmitted to the stirring blade component. The reduction motor 1 can effectively process the sand ice layer with appropriate torque and speed.

[0042] Under normal operating conditions, the opto-coupler baffle 3 installed on the side wall of the rotating shaft 2 rotates synchronously with the rotating shaft 2. Due to the position design of the opto-coupler baffle 3, it will continuously block or pass through the light beam path of the opto-coupler switch 4 installed in the inner cover 8 of the evaporator during rotation. This dynamic change enables the opto-coupler switch 4 to detect whether the rotating shaft 2 is in a normal rotating state.

[0043] If for some reason, such as the stirring blade encountering a particularly thick ice layer and getting stuck, resulting in the rotating shaft 2 stopping rotating, then the opto-coupler baffle 3 that originally rotated with the rotating shaft 2 will also stop moving. At this time, the opto-coupler switch 4 will no longer sense the change in the light beam path because it is no longer blocked periodically. After detecting this abnormal situation, the opto-coupler switch 4 will immediately send a signal to the machine control system, indicating that there is a blockage or other problem currently.

[0044] The above description is only the preferred embodiment of the present invention, and does not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
