Description

Technical Field

[0001] This utility model relates to the field of snowplow technology, specifically a dual-system snow sweeping and blowing vehicle with a roller brush and a centrally located power output. Background Technology

[0002] Frequent snowfalls result in large snow accumulations on roads, posing significant safety hazards, increasing the risk of traffic accidents, and disrupting normal traffic flow. Therefore, timely and effective snow removal is crucial for ensuring road safety and smooth traffic flow.

[0003] Currently, there are many types of snow removal vehicles on the market, but some snow removal vehicles have problems such as poor snow removal effect, limited functions, and inconvenient operation. Most snow removal vehicles can only rely on roller brushes for sweeping, which is difficult to completely remove thick snow or icy roads. In addition, some snow removal vehicles have unreasonable power system designs, resulting in insufficient power during operation and affecting work efficiency. In order to solve these problems, this utility model provides a dual-system snow removal and blowing vehicle with roller brush and centrally located power output. Utility Model Content

[0004] The purpose of this invention is to provide a dual-system snow sweeping and blowing vehicle with a roller brush and a centrally located power output, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-system snow sweeping and blowing vehicle with a centrally located power output and a roller brush, comprising a vehicle body,

[0006] The vehicle body is divided into a fan carriage and an auxiliary engine carriage. The fan carriage is equipped with a rear fan assembly for blowing and sweeping snow from the road surface.

[0007] The front end of the vehicle body is connected to and installed with a roller brush frame via a front vehicle body connecting frame. A front roller brush is installed on the roller brush frame, and the front roller brush is connected to a T-shaped reduction gearbox set in the middle of the roller brush shaft.

[0008] The vehicle body is also equipped with a chassis drive system at the bottom, and the auxiliary engine housing and the chassis drive system work together to output power through a T-type reduction gearbox.

[0009] Further, the rear fan assembly includes a fan housing, a high-voltage motor inside the fan housing drives the blades inside the fan housing, and air supply sections are installed on both sides of the fan housing to deliver high-speed flowing air to the road surface through the air supply sections.

[0010] Further, the air supply section includes upper air ducts fixed to both sides of the output end of the fan casing. A lower air duct is sleeved at the end of the upper air duct. The upper and lower air ducts are connected by several height adjustment cylinders. A wind direction adjustment plate is hinged at the end of the lower air duct. Several wind direction adjustment cylinders for adjusting the angle of the wind direction adjustment plate are installed on the lower air duct.

[0011] Further, the upper air duct is inclined downwards, and a fan mounting bracket is provided in the middle of the fan housing. The fan housing is installed in the fan carriage through the fan mounting bracket.

[0012] Furthermore, when the chassis drive system stops, the auxiliary engine in the auxiliary engine housing supplies power to the T-type reduction gearbox via a hydraulic motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This dual-system snow sweeper and blower with a centrally located power output uses a control system to switch between the hydraulic power of the chassis and the auxiliary engine. The auxiliary engine housing and chassis drive system cross-output power to a T-type reduction gearbox, achieving flexible power switching. This avoids situations where the equipment cannot work due to a failure of a single power source, thus improving the reliability of the equipment and the continuity of operation.

[0015] Meanwhile, the roller brush eliminates the common dual-motor arrangement on both sides in the market. Instead, a T-shaped reduction gearbox is installed in the middle of the left and right drive shafts, and the hydraulic motor is installed at the input end of the gearbox. This increases the torque while ensuring the same snow removal speed. Compared with ordinary roller brushes, it can sweep away thicker snow and output more torque. The motor is also installed in the middle of the roller brush, which reduces the overall width while ensuring the effective working width, improving vehicle passability and reducing the accident rate.

[0016] In addition, the front roller brush and rear fan assembly allow the front roller brush to perform preliminary cleaning of the snow on the road surface, gathering or pushing the snow to the sides of the road, while the rear fan assembly can blow away the remaining snow or thin ice by using high-speed airflow. This achieves dual cleaning of the snow on the road, improves the snow removal effect, and ensures that the road is clean and tidy. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-2 As shown, this utility model provides a technical solution: a dual-system snow sweeping and blowing vehicle with a roller brush and a centrally located power output, including a vehicle body 9. The vehicle body 9 is divided into a blower box 1 and an auxiliary engine box 2. The blower box 1 is equipped with a rear blower assembly 3, which is used to blow snow onto the road surface.

[0022] A roller brush frame 5 is connected to the front of the vehicle body 9 via a front body connecting frame 4. A front roller brush 6 is mounted on the roller brush frame 5. The front roller brush 6 is driven by a T-shaped reduction gearbox 7 located in the middle of the roller brush shaft, achieving dual-side drive of the roller brush. The T-shaped reduction gearbox 7 ensures the same snow removal speed on both sides of the roller brush while increasing torque, allowing it to remove thicker snow accumulations compared to ordinary roller brushes. The centrally located split-drive torque-increasing design provides greater output torque, and the motor is mounted in the middle of the roller brush, reducing the overall width while maintaining the effective working width, improving vehicle maneuverability and reducing the accident rate. At the bottom, there is also a chassis drive system 8. The auxiliary engine housing 2 and the chassis drive system 8 cross each other to output power to the T-type reduction gearbox 7. The system is controlled by the control system. When the front roller brush 6 is needed for snow removal, if the chassis drive system 8 is stopped, the auxiliary engine in the auxiliary engine housing 2 supplies power to the T-type reduction gearbox 7 through the hydraulic motor to drive the front roller brush 6 to rotate. If the auxiliary engine in the auxiliary engine housing 2 is stopped, the chassis drive system 8 supplies power to the T-type reduction gearbox 7 through the hydraulic motor to ensure that the front roller brush 6 can work normally.

[0023] The full-power power take-off (PTO) is installed between the transmission and the engine in the chassis drive system 8, connected to the engine crankshaft and the transmission input shaft. It can directly obtain full power from the engine. When the chassis drive system 8 needs to supply power to the T-type reduction gearbox 7, the driver issues a command through the control device in the vehicle. At this time, the full-power PTO transmits the power output from the engine to the output shaft of the PTO. The output shaft is connected to the hydraulic pump, and the power drives the hydraulic pump to run. The hydraulic pump converts mechanical energy into hydraulic energy, causing the hydraulic oil to form a high-pressure oil flow in the closed hydraulic pipeline. The high-pressure oil flow drives the hydraulic motor to rotate, and the hydraulic motor then converts the hydraulic energy into mechanical energy and transmits it to the T-type reduction gearbox 7, ultimately providing power to the front roller brush 6.

[0024] Thanks to the adoption of a full-power PTO, the engine's power can be utilized to the maximum extent, ensuring sufficient power to supply the front roller brush 6. Even under heavy loads such as handling thick snow, the front roller brush 6 can operate stably and efficiently. At the same time, the full-power PTO has high power transmission efficiency and low energy loss, further improving the working efficiency of the entire power transmission system. Under normal conditions, the auxiliary engine transmits power to the hydraulic motor to power the T-type reduction gearbox 7. When the chassis drive system 8 needs to power the T-type reduction gearbox 7, the control system realizes power transmission through the link from the driver's operation control device to the actuator. The driver issues a power supply command through in-vehicle control devices such as buttons. After receiving the command, the control system triggers the full-power PTO in the chassis drive system 8 to work, which transmits the engine power to the hydraulic pump, and then drives the hydraulic motor through hydraulic oil, ultimately powering the T-type reduction gearbox 7.

[0025] The rear fan assembly 3 includes a fan housing 301. A high-voltage motor is installed inside the fan carriage 1. The high-voltage motor drives the blades inside the fan housing 301 to rotate, causing high-speed airflow inside the fan housing 301. Air supply sections are installed on both sides of the fan housing 301. The high-speed airflow is delivered to the road surface through the air supply sections to achieve the purpose of blowing away snow.

[0026] The air supply section includes an upper air duct 302 fixed to both sides of the output end of the fan housing 301. The upper air duct 302 is inclined downwards, which helps to guide the airflow to the road surface. A lower air duct 303 is sleeved at the end of the upper air duct 302. The upper air duct 302 and the lower air duct 303 are connected by several height adjustment cylinders 304. By controlling the extension and retraction of the height adjustment cylinders 304, the height of the lower air duct 303 can be adjusted to adapt to different road conditions and snow thickness. A wind direction adjustment plate 307 is hinged at the end of the lower air duct 303. Several wind direction adjustment cylinders 306 are installed on the lower air duct 303 to adjust the angle of the wind direction adjustment plate 307. By controlling the extension and retraction of the wind direction adjustment cylinders 306, the angle of the wind direction adjustment plate 307 can be changed, thereby adjusting the jet direction of the airflow and improving the purging effect.

[0027] A fan mounting bracket 305 is provided in the middle of the fan housing 301. The fan housing 301 is installed in the fan carriage 1 through the fan mounting bracket 305, which ensures the stability of the fan housing 301 during operation.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
