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 indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0021] like Figures 1 to 5 A mid-mounted power output roller brush is shown, comprising an engine 1, a reduction box 2, a transmission mechanism A and an output shaft coupling 3; the engine 1 is connected to a reduction box input shaft 12 of the reduction box 2, the reduction box output shaft 13 of the reduction box 2 is connected to the output shaft coupling 3 through the transmission mechanism, and the two ends of the output shaft coupling 3 are symmetrically connected to roller brush half shafts 4, and the roller brush half shafts 4 are respectively provided with bristles;

[0022] The transmission mechanism includes a first gear 5, a second gear 6, a third gear 7, a fourth gear 8, a first sprocket 9, a second sprocket 10 and a chain 11; the first gear 5 is arranged on a reduction box input shaft 12, the second gear 6 is meshed with the first gear 5, the second gear 6 and the third gear 7 are both arranged on a reduction box output shaft 13, the fourth gear 8 is meshed with the third gear 7, the fourth gear 8 and the first sprocket 9 are both arranged on a sprocket box input shaft 14, the first sprocket 9 and the second sprocket 10 are connected by a chain 11, and the second sprocket 10 is provided with an output shaft coupling 3.

[0023] When the central power output roller brush of the utility model is in use, the engine 1 is first started, and the engine 1 drives the reduction box input shaft 12 to rotate. Since the reduction box input shaft 12 is provided with a first gear 5, after the reduction box input shaft 12 rotates, the first gear 5 is driven to rotate, and the first gear 5 is meshed with the second gear 6. The second gear 6 and the third gear 7 are both arranged on the reduction box output shaft 13. After the first gear 5 rotates to drive the second gear 6 to rotate, the reduction box output shaft 13 is driven to rotate, and then the third gear 7 is driven to rotate. Since the fourth gear 8 is meshed with the third gear 7, the fourth gear 8 rotates, and since the fourth gear 8 is meshed with the third gear 7, the fourth gear 8 rotates. The four gears 8 and the first sprocket 9 are both arranged on the sprocket box input shaft 14. When the fourth gear 8 rotates to drive the sprocket box input shaft 14 to rotate, the first sprocket 9 rotates. The first sprocket 9 and the second sprocket 10 are connected by the chain 11, so as to realize the rotation of the second sprocket 10. The second sprocket 10 is provided with an output shaft coupling 3. When the second sprocket 10 rotates, the output shaft coupling 3 is driven to rotate. The two ends of the output shaft coupling 3 are respectively provided with a roller brush half shaft 4. When the output shaft coupling 3 rotates, the two roller brush half shafts 4 are driven to rotate, so as to realize the rotation of the bristles on the roller brush half shaft 4, and realize the snow removal and snow sweeping steps. The central power output roller brush of the utility model sets the output shaft coupling 3 in the middle of the two roller brush half shafts. Compared with the existing roller brush shaft integrally formed with one long shaft, the two roller brush half shafts of the utility model are simpler to process and assemble, convenient to operate, time-saving and labor-saving, and greatly improve the assembly efficiency of the roller brush.

[0024] As a preferred embodiment, the engine 1, reduction box 2, transmission mechanism A and output shaft coupling 3 in the present application are arranged at the middle position of the two roller brush half shafts 4, that is, the power drive and transmission mechanism in the present application are located in the middle of the two roller brush half shafts, realizing the power drive of the two roller brush half shafts 4 and the central drive of the transmission mechanism; the two roller brush half shafts of the present application are simple to process and short in length, and the transmission mechanism A and the output shaft coupling 3 are concentrated in the middle of the two roller brush half shafts, realizing the central installation layout of the power drive transmission mechanism, with a more compact structure and more convenient assembly; the two ends of the output shaft coupling 3 are respectively connected to the roller brush half shafts 4 through the roller brush shaft coupling, and the other end of each roller brush half shaft 4 is detachably arranged on the roller brush half shaft mounting seat 15. More preferably, the roller brush half shaft 4 is arranged on the roller brush half shaft mounting seat 15 by bolts. Since the bristles are consumable parts, when replacing the bristles of the roller brush, since the existing roller brush shaft is an integral long shaft, the roller brush shaft is driven by a single-side drive or a double-side drive, when replacing the bristles of the roller brush, it is necessary to remove the bearing seats on both sides of the roller brush shaft and the single-side or double-side transmission chains, which is very inconvenient and has low replacement efficiency; and when the bristles of the central power output roller brush of the present application are damaged and need to be replaced, it is only necessary to remove the bolts on the roller brush half-shaft 4 and the roller brush half-shaft mounting seat 15, pull out the roller brush half-shaft mounting seat 15, so that the roller brush shaft coupling of the roller brush half-shaft 4 is separated from the output shaft coupling 3, and then the roller brush half-shaft 4 can be removed, and the bristles can be quickly replaced to achieve the replacement of the bristles. After replacing the bristles, the roller brush is installed on the output shaft coupling 3 and the roller brush half-shaft mounting seat 15, and the installation method and disassembly method of the roller brush are in the opposite order. The central power output roller brush of the present application does not need to remove the chain when replacing the bristles, and replacing the bristles is more convenient and efficient.

[0025] As a preferred embodiment, the first sprocket 9, the second sprocket 10 and the chain 11 in the present application are all arranged in the sprocket box 16; the engine 1, the reduction box 2 and the sprocket box 16 are all arranged on the roller brush swing frame 17; the roller brush swing frame 17 supports the engine 1, the reduction box 2 and the sprocket box 16 to ensure the stability of the mid-mounted power output roller brush. The engine 1 in the present application is arranged on an engine mounting bracket 18, and the support of the engine mounting bracket 18 is achieved by a roller brush swinging bracket 17, thereby achieving support for the engine 1; and the engine mounting bracket 18 is arranged on the left side of the forward direction of the roller brush swinging bracket 17. When the roller brush is used to remove snow and sweep snow, the roller brush will deflect to the right by a certain angle, and the driver will look to the right to ensure the distance between the right roller brush and the road cliff. Compared with the existing engine position in front of the right of the driver, which will cause obstruction of the line of sight, the engine mounting bracket 18 and the engine 1 arranged on the left side of the forward direction in the present application, the driver has a wide field of vision and no blind spots when the roller brush is in operation, which ensures a safe distance between the roller brush and the road cliff, and ensures the safety and stability of the roller brush for snow removal and sweeping.
