Description

Technical Field

[0001] The utility model relates to the technical field of road sweeper, in particular to a one-drive-four brush power transmission integrated mechanism for a sanitation road sweeper. Background Art

[0002] Most of the traditional sanitation road sweepers on the market generally adopt four brushes, including two side brushes and two middle brushes, which are installed at the front of the vehicle or on the frame girder for garbage cleaning and collection. The installation positions and operation of the brushes are independent of each other. Usually, a set of hydraulic motor or reduction motor is configured for each brush as the power source for driving the brush to rotate. For four brushes, four motors or motors are required, resulting in high costs. Moreover, a large number of power source parts also mean a doubled probability of failures. The whole system has a complex structure, numerous pipe bundles and control systems, and a large weight. Therefore, a one-drive-four brush power transmission integrated mechanism for a sanitation road sweeper is proposed. Content of the Utility Model

[0003] The purpose of the utility model is to solve any of the above problems, and thus a one-drive-four brush power transmission integrated mechanism for a sanitation road sweeper is proposed, including a supporting seat, a driving motor and a first right-angle gearbox arranged on the supporting seat. The output end of the driving motor is fixedly connected to the input shaft of the first right-angle gearbox. On both sides of the top of the supporting seat, second right-angle gearboxes are symmetrically arranged. Two middle brushes and two side brushes are arranged at the bottom of the supporting seat, and the middle brushes are fixedly connected to the output shafts at the bottoms of the second right-angle gearboxes.

[0004] Further, the output shafts on both sides of the first right-angle gearbox are respectively connected to the input shafts of the second right-angle gearboxes on both sides of the supporting seat through universal joints.

[0005] Further, a connecting seat is arranged at the connection between the middle brush and the second right-angle gearbox. A connecting seat is also fixedly installed at the central position of the top of the side brush. Pulley wheels are arranged at the tops of the connecting seats on the middle brush and the side brush, and a transmission belt is arranged between the two pulley wheels for connection.

[0006] Further, a first supporting rod is hinged on the connecting seat of the middle brush, and a second supporting rod is hinged on the connecting seat of the side brush. A sleeve is arranged between the first supporting rod and the second supporting rod for connection, and the sleeve is threadedly connected to the first supporting rod and the second supporting rod.

[0007] Further, two screw rods are movably installed on both sides of the supporting seat. One end of the screw rod is connected with a tension spring, and the other end of the tension spring is fixedly connected to the sleeve.

[0008] Beneficial effects: Through the transmission combination of the rigid right-angle gearbox and the flexible pulley, the present utility model effectively converts the horizontal rotation of a single power source into four coordinated vertical rotations, having the advantages of simple structure and high transmission efficiency. At the same time, driving four sweeping brushes by a single power source significantly reduces the number of power source parts, resulting in lower costs and effectively reducing the probability of faults.

To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model.

[0017] Next, a one-drive-four sweeping brush power transmission integration mechanism of a sanitation sweeper according to an embodiment of the present utility model will be described with reference to the drawings, as Figures 1 to 4As shown in the figure, the one-drive-four-brush power transmission integrated mechanism of the sanitation sweeper includes a support seat 1, a driving motor 2 and a first right-angle gearbox 4 provided on the support seat 1. The output end of the driving motor 2 is fixedly connected to the input shaft of the first right-angle gearbox 4. On both sides of the top of the support seat 1, second right-angle gearboxes 5 are symmetrically provided. At the bottom of the support seat 1, two middle sweeper brushes 6 and two side sweeper brushes 7 are provided. The middle sweeper brush 6 is fixedly connected to the output shaft at the bottom of the second right-angle gearbox 5.

[0018] Preferably, the output shafts on both sides of the first right-angle gearbox 4 are respectively connected to the input shafts of the second right-angle gearboxes 5 on both sides of the support seat 1 through universal joints.

[0019] In a specific embodiment: Four top rods 3 are symmetrically installed on the top of the support seat 1. The support seat 1 is installed on the sweeper through the four top rods 3. At the same time, the top rods 3 can be connected to the base lifting mechanism of the sweeper, so that the lifting adjustment of the four sweeper brushes can be realized simultaneously. The driving motor 2 can be a reduction motor or a hydraulic motor; when in use, by starting the driving motor 2, the power of the driving motor 2 will be transmitted into the second right-angle gearboxes 5 on both sides through the setting of the first right-angle gearbox 4, and the middle sweeper brush 6 at the bottom of the second right-angle gearbox 5 will be driven to rotate.

[0020] Preferably, a connecting seat 8 is provided at the connection between the middle sweeper brush 6 and the second right-angle gearbox 5. A connecting seat 8 is also fixedly installed at the central position of the top of the side sweeper brush 7. Pulley wheels 9 are provided at the tops of the connecting seats 8 on the middle sweeper brush 6 and the side sweeper brush 7, and a transmission belt 10 is provided to connect the two pulley wheels 9.

[0021] Preferably, a first support rod 11 is hingedly provided on the connecting seat 8 of the middle sweeper brush 6, and a second support rod 13 is hingedly provided on the connecting seat 8 of the side sweeper brush 7. A sleeve 12 is provided to connect the first support rod 11 and the second support rod 13. The sleeve 12 is threadedly connected to the first support rod 11 and the second support rod 13. By rotating the sleeve 12, the first support rod 11 and the second support rod 13 can be driven to approach or move away from each other, thereby driving the pulley wheels 9 at the tops of the two connecting seats 8 to approach or move away from each other, so as to realize the tension adjustment of the belt 10.

[0022] Preferably, two screw rods 15 are movably installed on both sides of the support seat 1. One end of the screw rod 15 is connected with a tension spring 14, and the other end of the tension spring 14 is fixedly connected to the sleeve 12.

[0023] In a specific embodiment: when the second gear box 5 drives the middle sweeping brush 6 and the connecting seat 8 on the top thereof to rotate, the connecting seat 8 on the top of the side sweeping brush 7 will be driven to rotate under the transmission of the transmission belt 10, thereby driving the side sweeping brush 7 to rotate synchronously; when the camber angle of the side sweeping brush 7 needs to be adjusted, by rotating the screw rod 15, the screw rod 15 will pull the tension spring 14, and the tension spring 14 will pull the sleeve 12 outward, and the sleeve 12 will synchronously drive the first support rod 11 and the second support rod 13 to swing outward, and drive the side sweeping brush 7 to swing outward through the second support rod 13, thereby realizing the adjustment of the camber angle of the side sweeping brush 7 to meet the needs of different roads. At the same time, the middle sweeping brush 6 and the side sweeping brush 7 are connected by the pulley 9 for transmission, which is convenient for the retraction and release of the side sweeping brush 7 and the elastic torsion avoidance after hitting the curb during work.

[0024] Working principle: the driving motor 2 as the power source first transmits the power to the first right-angle gearbox 4, and the first right-angle gearbox 4 transmits the power to the two middle sweeping brushes 6 in a one-to-two form through the two second right-angle gearboxes 5, thereby driving the two middle sweeping brushes 6 to rotate synchronously. Afterwards, the pulley 9 and the transmission pulley 10 are used to transmit power between the middle sweeping brush 6 and the side sweeping brush 7 rotating in the same vertical axis direction, thereby completing the one-to-four function of the driving motor 2. This transmission combination of a rigid right-angle gearbox and a flexible pulley effectively converts the horizontal rotation of a single power source into four coordinated vertical rotations, and has the advantages of simple structure and high transmission efficiency.
