Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Referring to fig. 1 to 8, an embodiment of the present application provides a device with a scraper bar capable of reciprocating, which is applied to a sweeper, the sweeper comprises a housing, the device comprises a motor assembly 1, a first side brush 2, a first rotating member 3, a second rotating member 4, a connecting shaft 5, a moving bracket 6 and a scraper assembly; the motor assembly 1 comprises an output shaft which is connected with the first side brush 2; the first rotating piece 3 is sleeved on the output shaft; the first rotating piece 3 is in transmission connection with the second rotating piece 4 and drives the second rotating piece 4 to rotate; the connecting shaft 5 is arranged on the surface of the second rotating piece 4 away from the axis line of the second rotating piece; the moving bracket 6 is sleeved on the connecting shaft 5 along the height direction of the connecting shaft 5 and is connected with the connecting shaft 5 in a sliding way; the movable support is connected with the spatula assembly, and the movable support 6 drives the spatula assembly to reciprocate.
In the above embodiment, the motor assembly 1 can drive the spatula assembly to reciprocate while driving the first side brush 2 to rotate.
The motor assembly 1 comprises a motor and a speed reducing mechanism, wherein the motor provides power, and the speed reducing mechanism adds or reduces the rotating speed or torque force through meshing gears with different sizes, so that the rotating speed of the motor is adjusted to a proper value. The output shaft of the motor assembly 1 outputs torque to rotate, part of the structure of the output shaft extends out of the shell, the first side brush 2 is connected with the part of the structure of the output shaft, and the output shaft drives the first side brush 2 to rotate.

The connecting shaft 5 is movably connected with the second rotating member 4, so that the moving bracket 6 cannot rotate around the rotating center of the second rotating member 4 due to the rotation of the connecting shaft 5. Explanation: since the rotation track of the second rotating member 4 is circular, the connecting shaft 5 is disposed on the surface of the second rotating member 4, and therefore the connecting shaft 5 moves around the rotation center of the second rotating member 4, and the movement track is circular. When the connecting shaft 5 moves, not only the entire position but also the position of the structure itself of the connecting shaft 5 is changed relative to the initial position, which corresponds to the rotation of the connecting shaft 5. If the connecting shaft 5 is fixedly connected with the moving support 6, on the one hand, the overall position of the moving support 6 can be changed, and on the other hand, the connecting shaft 5 rotates, and the moving support 6 also rotates, then the overall moving track of the moving support 6 is a circular track rotating around the rotating circle center of the second rotating member 4, so that enough space needs to be reserved inside the sweeper to enable the moving support 6 to move, and space is wasted in the mode. The moving bracket 6 is sleeved on the connecting shaft 5 and is in sliding connection with the connecting shaft 5, so that the rotation of the connecting shaft 5 cannot cause the position change of the moving bracket 6, and the moving bracket 6 only moves along with the integral position change of the connecting shaft 5, so that the movement of the moving bracket 6 is the displacement change when a certain point on the circle moves.
