[0002] As an important device for snow removal in winter, the snow sweeper has significant advantages such as high efficiency, economy, and environmental protection. With the increasing economy and social progress, snow removal equipment has been gradually promoted and used at home and abroad. Currently, small mechanical snow sweepers mainly consist of a prime mover, a transmission device, a snow collection device, a snow throwing device, a traveling system, and an operating system. The prime mover can use an electric motor or an engine, and currently, most use gasoline engines or diesel engines; the snow collection device is used to collect snow, and mainly uses a starting pull disc as the starting mechanism of the snow sweeper. Therefore, when a fault occurs in the existing starting pull disc of the snow sweeper, it is necessary to quickly disassemble the top cover of the pull disc for maintenance. However, most of the connections between the starting pull disc and the top cover are fixed by screwing, so the disassembly and assembly are relatively troublesome and tools are required. For this reason, we propose a starting motor device for a snow sweeper with automatic preheating. Summary of the Invention

The convenient disassembly and repair mechanism includes: a connection limit component and a locking component.

[0020] In this embodiment, preferably, the connection limit component includes connection grooves 100 symmetrically opened at the top of the motor base 1 and connection blocks 101 symmetrically fixed at the bottom of the top cover 2. By engaging the connection blocks 101 with the connection grooves 100, it is convenient to connect the top cover 2 and the motor base 1.

[0021] In this embodiment, preferably, a guiding groove 200 is opened inside the connection block 101, and a guiding block 201 is fixed on one side of the inner wall of the connection groove 100. The guiding block 201 is engaged with the guiding groove 200.

[0022] In this embodiment, preferably, limiting grooves 300 are symmetrically opened at both ends of the connection block 101, built-in grooves 301 are symmetrically opened at both ends of the inner wall of the connection groove 100, a limiting buckle 302 is arranged inside the built-in groove 301. By engaging the limiting buckle 302 with the limiting groove 300, the connection block 101 can be temporarily limited inside the connection groove 100. A built-in spring 303 is connected between the limiting buckle 302 and the built-in groove 301, which is convenient to drive the limiting buckle 302 to reset and pop up.

[0023] In this embodiment, preferably, sliding grooves 400 are symmetrically opened on the inner wall of the built-in groove 301, and sliding blocks 401 are symmetrically fixed on both sides of the limiting buckle 302. By sliding the sliding blocks 401 in the sliding grooves 400, it can play a guiding role when driving the limiting buckle 302 to move.

[0024] In this embodiment, preferably, the locking component includes a positioning hole 500 opened on the outside of the connection block 101. Grooves 501 are symmetrically opened on the surface of the motor base 1. A through hole 502 is penetrated through the inside of the groove 501. A locking rod 503 that passes through the inside of the through hole 502 and is connected to the positioning hole 500 is arranged inside the groove 501. The locking rod 503 is screwed and fixedly connected to the positioning hole 500, which can lock and position the connection block 101 that is inserted into the connection groove 100.

Then pull the top cover 2 to separate it from the motor base 1, and drive the connecting block 101 to exit from the inside of the connecting groove 100. At the same time, squeeze the limit buckle 302, and the built-in spring 303 of the limit buckle 302 exits from the inside of the limit groove 300 and retracts into the inside of the built-in groove 301 under the external force extrusion, then the connecting block 101 can be separated from the connecting groove 100, and at the same time drive the guide groove 200 and the guide block 201 to slide and separate, then the connecting block 101 can exit from the inside of the connecting groove 100, and then the top cover 2 can be separated from the motor base 1. Subsequently, the device inside the motor base 1 can be repaired. When it is necessary to dissipate the heat generated inside the motor base 1, heat dissipation can be carried out through the heat dissipation port 600, and the dustproof net 601 plays a dustproof role.
