Description

Technical Field

[0001] The utility model belongs to the technical field of snow removal equipment, and in particular relates to a snow removal roller brush driven by a single motor. Background Art

[0002] With the development of the economy and society, rainy and snowy weather in winter greatly affects people's travel convenience. When the snow is heavy, airports and municipal sanitation departments often use snow removal roller brushes to clear snow. For example, the Chinese utility model patent with application number 201922289581.6 discloses an intelligent roller brush device. Traditional snow removal roller brushes mostly use chassis vehicle power to provide power for road snow removal operations, but the use of chassis vehicle power takes a large change to the vehicle chassis, and it is necessary to add hydraulic oil tanks, hydraulic oil radiators, transmission shafts and other components, making the snow removal roller brush as a whole large and bulky. To solve this problem, there is also a self-powered snow removal roller brush, which can realize the snow removal roller brush to perform snow removal operations only by its own power system. This improvement scheme abandons the snow removal roller brush relying on the vehicle chassis to provide power, but the traditional self-powered snow removal roller brush mostly uses diesel engines, and the diesel engine also needs to be equipped with many accessories such as radiators and transmission shafts, resulting in a complicated and bulky power system, which increases the difficulty of production and manufacturing and increases the production and manufacturing costs. On the other hand, as the national environmental protection situation becomes more and more severe, environmental protection has become more and more stringent. According to the national green environmental protection needs, relevant departments have higher and higher emission standards for fuel engines, resulting in a small application range of snow removal roller brushes and inability to cope with multi-scenario snow removal operations. In addition, most existing snow removal roller brushes can only adjust the roller core height and horizontal deflection angle, and cannot adjust the roller core in the longitudinal direction. The pitch angle, thus unable to adjust the roller core, roller brush blade and ground contact angle, cannot be adjusted according to the actual terrain and snow removal amount. Utility Model Content

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A snow-removing roller brush driven by a single motor comprises a fixed frame, one end of a tripod is hinged to the fixed frame and the other end is hinged to a floating frame, a deflection frame is rotatably connected to the floating frame, a sub-beam is fixedly connected to the deflection frame, a connecting frame is rotatably connected to the sub-beam, and a roller core is rotatably connected to the connecting frame; a cylinder body of a lifting cylinder is hinged to the lower part of the fixed frame and a telescopic rod thereof is hinged to the tripod, a cylinder body of a deflection cylinder is hinged to both sides of the fixed frame and a telescopic rod thereof is hinged to the deflection frame, and a pitch mechanism for driving the connecting frame to rotate is arranged on the deflection frame; a motor is fixedly connected to the connecting frame, an output shaft of the motor is connected to an input shaft of a reducer, and the reducer drives the roller core to rotate via a chain transmission mechanism.

When the roller core needs to be in a floating snow removal state, the hydraulic valve group connects the oil inlet and oil return port of the lifting cylinder. When the roller core needs to be in a forced downward pressure snow removal state, the hydraulic valve group disconnects the oil inlet and oil return port of the lifting cylinder.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Example

[0024] See also Figures 1 to 6 As shown, a snow removal roller brush driven by a single motor includes a fixed frame 11, which is a frame structure formed by two horizontal and two vertically arranged channel steels. One end of the tripod is hinged to the fixed frame 11 and the other end is hinged to the floating frame 12. In order to improve the overall connection strength of the utility model, in this embodiment, the tripod includes an upper tripod 13 and a lower tripod 14 respectively arranged at the upper and lower parts of the fixed frame 11. The bottom ends of the upper tripod 13 and the lower tripod 14 are rotatably connected to the fixed frame 11 through a pin structure, and the top ends of the upper tripod 13 and the lower tripod 14 are hinged to the floating frame 12 through a pin structure. Therefore, through the above structure, the upper tripod 13 and the lower tripod 14 can drive the floating frame to move up and down when rotating with the pin structure at the bottom as the axis. In this embodiment, the bottom of the tripod is set to be one end close to the fixed frame 11, and the top of the tripod is set to be one end close to the floating frame 12.

[0025] The cylinder body of the lifting cylinder 21 is hinged to the lower part of the fixed frame 11 through the cylinder ear plate and the pin structure, and the telescopic rod of the lifting cylinder 21 is hinged to the upper tripod 13. Therefore, the telescopic rod of the lifting cylinder 21 can drive the upper tripod 13 and the lower tripod 14 to rotate to drive the floating frame 12 to move up and down, thereby realizing the lifting function of the snow removal roller brush. In order to achieve the floating frame always perpendicular to the ground when adjusting up and down as much as possible, a connecting ear plate 15 is welded to the upper end surface of the upper tripod 13 near the floating frame 12, and a waist-shaped sliding through hole 151 is opened on the connecting ear plate 15. The telescopic rod of the lifting cylinder is set in the sliding through hole 151 through the pin structure, and the pin of the pin structure can slide in the sliding through hole 151.

[0026] The floating frame 12 is rotatably connected with a deflection frame 16 through a pin structure. The deflection frame 16 is in a vertical state and can be rotated with the pin structure as an axis. A sub-beam 17 is fixedly connected to the end face of the deflection frame 16 on the side away from the fixed frame 11 through bolts. A support shaft 171 is welded or fixedly embedded on the sub-beam 17 along its length direction. A connecting frame 18 is rotatably sleeved on the support shaft 171, and a roller core 19 is rotatably connected to the connecting frame 18. A roller brush piece (not shown in the figure) can be fixedly installed on the roller core 19, and the roller brush piece is driven to rotate by driving the roller core 19 to complete the snow removal operation.

[0027] In order to realize the rotation of the deflection frame 16 to drive the connection frame 18 and the roller core 19 to rotate, thereby realizing the horizontal deflection function of the utility model, the utility model is provided with a deflection oil cylinder 22, and a U-shaped hinge frame 221 is hingedly connected at the bottom of the cylinder body of the deflection oil cylinder 22 and the top of the telescopic rod through a pin structure, and the hinge frames at the bottom of the cylinder body of the deflection oil cylinder 22 and the top of the telescopic rod are respectively hingedly connected to the fixed frame 11 and the deflection frame 16 through a pin structure. The pins hinged on the deflection oil cylinder 22 and the corresponding pins on the fixed frame 11 and the deflection frame 16 are at a certain angle to each other, such as 90 degrees vertical arrangement. Therefore, the deflection frame 16, the auxiliary beam 17, the connection frame 18 and the roller core 19 can be driven to deflect by the extension and retraction of the telescopic rod of the deflection oil cylinder 22.

[0028] See also Figure 6 As shown, a pitch mechanism for driving the connection frame 18 to rotate is provided on the deflection frame 16. Specifically, the pitch mechanism includes a pitch cylinder 23. The cylinder body of the pitch cylinder 23 is hingedly connected to the deflection frame 16 through a pin structure, and its telescopic rod is hingedly connected to the upper end surface of the connection frame 18 through a pin structure. Therefore, by extending and retracting the telescopic rod of the pitch cylinder 23, the connection frame 18 and the roller core 19 can be driven to rotate around the support shaft 171, thereby adjusting the pitch angle of the roller core 19 relative to the ground, so as to adjust the contact width of the roller core 19 with the ground, so as to perform adaptive adjustment according to different snow removal requirements.

[0029] See also Figure 4As shown, a motor 31 is fixedly installed on the middle part of the connecting frame 18 near the deflection frame 16 by bolts, and the output shaft of the motor 31 is connected to the input shaft of the reducer 33 through the transmission shaft 32 of the universal joint structure. The output shaft of the reducer 33 drives the roller core 19 to rotate through the chain transmission mechanism, that is, the output shaft of the reducer 33 can be fixedly connected to the main sprocket 34 through a key connection or a bolt fastening connection, and the roller core 19 is fixedly installed on the connecting frame 18 through a bearing and can rotate on the connecting frame 18. A slave sprocket (not shown in the figure) is fixedly connected to one end of the roller core 19, and the main sprocket 34 and the slave sprocket are connected through a transmission chain (not shown in the figure). The motor 31 can be connected to the battery pack of the chassis of the new energy vehicle through a power line, and the roller core 19 can be continuously variable by controlling the different speeds of the motor 31. In this embodiment, a mechanical transmission method is adopted between the motor 31 and the roller core 19, and the hydraulic oil tank, radiator and other components required for the hydraulic drive of the roller core 19 to rotate in the transmission snow removal roller brush are eliminated.

[0030] See also Figure 1 As shown, a snow guard 181 is provided at the front end of the connecting frame 18 to prevent the snow from returning during the snow removal operation from affecting the driver's sight. The utility model also includes a hydraulic valve group (not shown in the figure). In addition to the traditional functions of connecting and controlling the lifting cylinder 21, the deflection cylinder 22 and the pitch cylinder 23, the hydraulic valve group can also connect the oil inlet and the oil return port of the lifting cylinder 21 respectively. When the roller core 19 needs to be in a floating snow removal state, that is, the roller core 19 is adjusted to float with the ground, the hydraulic valve group connects the oil inlet and the oil return port of the lifting cylinder 21. When the roller core 19 needs to be in a forced downward pressure snow removal state, that is, the roller core 19 does not float with the ground, the hydraulic valve group disconnects the oil inlet and the oil return port of the lifting cylinder 21. The structure and principle of the hydraulic valve group are prior art and will not be repeated here.

[0031] Support wheels 172 are fixedly connected to both sides of the auxiliary beam 17 to protect the roller brush pieces on the roller core 19 to increase its service life.

[0032] Clearance lights 182 are fixedly connected to both sides of the connecting frame to remind drivers and pedestrians of the relative positions of the snow removal roller brushes.

[0033] The working process of the embodiment of the utility model is as follows:

[0034] The snow removal roller brush is installed according to the above structure and function description, and the fixing frame 11 of the snow removal roller brush is installed in front of the new energy vehicle, and the motor 31 is connected to the battery pack of the chassis of the new energy vehicle through the power line; in the actual snow removal process, the height of the roller core 19 can be adjusted by the lifting cylinder 21, the horizontal deflection angle of the roller core 19 can be adjusted by the deflection cylinder 22, and the pitch angle of the roller core 19 can be adjusted by the pitch cylinder 23; the motor 31 is started, and after being decelerated by the reducer 33, the main sprocket 34 is driven to rotate, thereby driving the chain, the follower sprocket, and the roller core 19 to rotate, thereby realizing the snow removal operation. By arranging the motor 31 and the snow removal roller brush in an integrated manner, the snow removal roller brush is made lighter as a whole, and the work efficiency is effectively improved. The central arrangement of the motor 31 can greatly improve the overall stability of the snow removal roller brush and increase the safety of the power system. The use of a motor to drive the roller core 19 avoids the different environmental requirements for fuel engine emission standards, meets environmental protection requirements and reduces production and manufacturing costs, can meet the needs of different snow removal work sites, and expand the application range of the snow removal roller brush.

[0035] In this process, the corresponding control device, hydraulic valve group, hydraulic auxiliary mechanism, motor 31, reducer 33's own structure and the connection method therebetween are all existing technologies and will not be repeated here, as long as they can meet the above working process.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
