[0045] As Figures 1 to 2As shown, the embodiment of the present application provides an electric screw type snow propeller, which comprises a mounting plate frame body 1, a driving motor 2, a screw 3, an electronic speed regulator 4, an adaptive positioning structure 5, a power supply structure 6 and a protective cover body 7, so as to convert electric energy into strong torque and output transmission to the screw 3 through the cooperation of the driving motor 2 and the electronic speed regulator 4, so that the screw 3 can effectively rotate and provide forward power based on snow, so as to realize the synchronous forward movement of the mounting plate frame body 1 and the structure connected thereto; at the same time, the adaptive positioning structure 5 can also adaptively position and dampen based on different snow hardness, thereby improving the overall stability of the device when moving in different snow hardness conditions. The specific settings are as follows:

[0046] Please refer to Figures 1 to 2 , the mounting plate frame body 1 comprises a driving mounting part 11, an extension positioning part 12 and a plate body connecting part 13 which are fixedly connected; wherein the height position of the driving mounting part 11 is higher than the height position of the plate body connecting part 13, and the extension positioning part 12 is located between the driving mounting part 11 and the plate body connecting part 13, so as to assemble the driving structure through the driving mounting part 11, assemble the connected structure through the plate body connecting part 13, and connect the driving mounting part 11 and the plate body connecting part 13 through the extension positioning part 12 respectively, so that the mounting plate frame body 1 as a whole maintains the connection and transmission function.

[0047] The driving motor 2 is correspondingly arranged below the driving mounting part 11, and the driving motor 2 has a torque output end, and the central rotating shaft of the screw 3 is connected to the torque output end through separable transmission assembly, so as to output strong torque to the screw 3 through the driving motor 2.

[0048] Specifically, the structure of the screw 3 can adopt but is not limited to a threaded screw and a paddle screw; wherein the distance between the outer thread outer edge of the threaded screw and the central rotating shaft thereof is less than the distance between the outer paddle outer edge of the paddle screw and the central rotating shaft thereof, so that the threaded screw is more suitable for the case where the snow hardness is higher, while the paddle screw is more suitable for the case where the snow hardness is lower. In addition, the central rotating shaft of the screw 3 and the torque output end are separably arranged, which can effectively change flexibly based on different snow hardness, thereby forming two power forms suitable for different snow hardness, i.e. threaded movement and paddle snow particle pushing, to ensure normal operation of the device and improve the functional applicability.

[0049] Preferably, the driving motor 2 and the screw 3 are provided with at least two groups arranged in parallel, so as to combine multiple groups of strong torque to provide greater forward power for the overall device.

[0050] More preferably, the thread of the threaded screw rod 3 can adopt, but is not limited to, a single helical thread, a double helical thread, and a multi-helical thread, so as to further improve the functional applicability of the structure.

The elastic member 54 is detachably fixed between the upper supporting plate 51 and the lower supporting plate 52, so as to make the spacing between the upper supporting plate 51 and the lower supporting plate 52 float up and down with the softness and hardness of the snow (different sinking degrees when being pressed), thereby playing a self-adaptive positioning and shock absorption role.

[0055] It should be noted that the elastic member 54 can adopt, but is not limited to, elastic bodies such as springs, tension springs, adjustable elastic shock-absorbing mechanisms such as air cylinders and hydraulic structures.
