Description

Technical Field

[0001] The present invention relates to the technical field of snow removal devices, in particular to a snow removal device combining a snow removal roller brush and a push shovel. Background Art

[0002] In winter road snow removal operations, roller brush snow removal equipment and push shovel snow removal equipment are widely used. When there is less snow, sweeping is used, and when there is thick snow, pushing is used. In order to integrate the two functions, there are always people researching snow removal devices that combine roller brush snow removal and push shovel snow removal. For example, the patent application number is 201610883233X, and the invention name is a push-broom integrated snow removal device. In traditional snow removal devices, the roller brush is usually fixedly installed inside the roller brush cover, and the contact between the roller brush and the ground is controlled by adjusting the overall height of the roller brush cover. However, this type of structure has exposed many problems in long-term use:

[0003] On the one hand, the core pain point is the reduced snow removal efficiency caused by wear of the snow removal roller brush. As the snow removal roller brush gradually shortens due to friction with the ground during continuous operation, the height of the snow removal roller cover must be continuously lowered to ensure effective snow removal and increase brush utilization. However, when the snow removal roller cover is lowered, its bottom edge will be closer to the ground, severely blocking the airflow channel generated by the high-speed rotation of the snow removal roller. As a result, the lifted snow cannot be smoothly discharged. Some of the snow is blocked by the snow removal roller cover and falls back into the cleared area, not only reducing snow removal efficiency but also causing secondary icing.

[0004] On the other hand, snowplows lack impact resistance. Traditional snowplows often have a rigid base. If they encounter obstacles like rocks or manhole covers, the impact force directly impacts the plow, causing deformation or damage to connecting parts. This requires frequent repairs and replacements, increasing operating costs.

[0005] Furthermore, the uncontrolled position of the support rollers also affects the lifespan of the device. Some snowplows lack effective retaining mechanisms, allowing the rollers to drift to the bottom of the snowplow brush when the device turns or bumps. This causes prolonged friction with the rotating brush, accelerating brush wear and increasing noise and energy consumption.

[0006] Finally, the lack of visual confirmation of the snowplow brush's contact status creates operational inconvenience. Operators in the cab cannot directly observe whether the snowplow brush is in contact with the ground or whether the contact pressure is appropriate. This can lead to the brush lifting off the ground, resulting in missed sweeps, or excessive pressure, exacerbating wear and tear, impacting operational accuracy and equipment life. Summary of the Invention

[0007] The object of the present invention is to provide a snow removal device combining a snow removal roller brush and a push shovel to solve the problems raised in the above background technology.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a snow removal device combining a snow removal roller brush and a push shovel, comprising a fixed axis and a snow removal roller brush cover that are fixedly connected, a snow removal roller brush is provided on the inner side of the snow removal roller brush cover, a snow push shovel is provided on the outer side of the snow removal roller brush cover, the snow push shovel and the snow removal roller brush cover are driven by a first hydraulic cylinder, support plates are rotatably provided on both sides of the fixed axis, the snow removal roller brush is provided between the two support plates, and the rotation between the support plate and the fixed axis is driven by a second hydraulic cylinder.

[0009] Preferably, the snow shovel includes a snow shovel body, the bottom of the snow shovel body is rotatably connected to a buffer base plate, and an elastic pushing member is provided between the buffer base plate and the snow shovel body.

[0010] Preferably, the elastic pushing member includes a guide support rod connected to both sides of the buffer base plate, the outer wall of the guide support rod is sleeved with a compression spring, and guide ear plates are fixed to the two hanging walls of the snow shovel body, and the guide support rod passes through the guide ear plates.

[0011] Preferably, a linkage rotating plate is provided at the bottom of the snow pusher, and both ends of the linkage rotating plate are rotatably connected to the snow pusher and the snow removal roller brush outer cover respectively.

[0012] Preferably, support shafts are provided on both sides of the outer wall of the fixed shaft, the outer wall of the support shaft is fixedly connected to a limiting nose rod, the bottom of the support shaft is connected to a supporting roller, a limiting slide groove is provided on the wheel frame of the supporting roller, and the limiting slide groove is coupled to the limiting nose rod.

[0013] Preferably, an indicator light is fixed to the support plate on one side, a pressure sensor is provided on the oil pipe of the driving motor of the snow removal roller brush, and the pressure sensor is connected to a PLC controller, which controls the power switch of the indicator light.

[0014] Preferably, guide grooves are provided on both sides of the outer wall of the snow removal roller brush cover, and protrusions are provided on the inner walls of the two support plates to be slidably connected to the guide grooves.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This combined snow removal device, featuring a brush and pusher blade, utilizes an independent support plate and a second hydraulic cylinder to independently adjust the brush's movement. When the brush shortens due to wear, the second hydraulic cylinder simply drives the support plate downward, ensuring contact with the ground without lowering the brush housing. This prevents the lowered brush housing from obstructing the snow removal path, ensuring that accumulated snow is smoothly lifted and discharged by the brush, maintaining efficient snow removal.

[0017] The buffer base plate at the bottom of the snow pusher is connected to the snow pusher body through an elastic pushing piece. When encountering an obstacle, it can flip around the connecting seat, absorb the impact force through elastic deformation, and reduce damage to the shovel body; at the same time, the setting of the linkage rotating plate enhances the connection strength between the snow pusher and the snow removal roller brush cover, reduces the force load of the first hydraulic cylinder, and extends the service life of the hydraulic components.

[0018] An arc-shaped limiting groove is provided on the wheel frame of the supporting roller, which is coupled with the limiting nose rod on the supporting shaft to strictly limit the rotation range of the supporting roller, preventing it from deviating to the bottom of the snow removal roller brush and causing friction and wear, thereby extending the replacement cycle of the snow removal roller brush and reducing maintenance costs.

[0019] The oil pressure changes of the snow removal roller brush drive motor are detected by a pressure sensor, and the brightness of the indicator light is adjusted in real time in combination with the PLC controller. The contact status of the snow removal roller brush and the ground is fed back to the operator in the cab in the form of an intuitive signal, which facilitates precise control of the snow removal roller brush pressure, reduces missed sweeps and excessive wear, and improves the level of intelligent operation.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-8 , the present invention provides a technical solution:

[0031] A snow removal device combining a roller brush and a pusher blade comprises a fixed shaft 1 and a roller brush housing 2. The fixed shaft 1 is connected to a lifting mechanism for adjusting height and a swing mechanism for adjusting orientation. A roller brush 5 for sweeping snow is mounted inside the roller brush housing 2, one end of which is connected to a drive motor.

[0032] A snow pushing shovel 3 is provided on the outside of the snow removal roller brush outer cover 2. The snow pushing shovel 3 and the snow removal roller brush outer cover 2 are driven by a first hydraulic cylinder 4. One end of the stator of the first hydraulic cylinder 4 is rotatably connected to the snow removal roller brush outer cover 2, and one end of the mover of the first hydraulic cylinder 4 is rotatably connected to the snow pushing shovel 3. The snow pushing shovel 3 can be driven to rise and fall by the first hydraulic cylinder 4.

[0033] Support plates 6 are rotatably mounted on either side of the fixed shaft 1 to support the snow removal roller brush 5. The snow removal roller brush 5 is positioned between the two support plates 6. Each support plate 6 is equipped with a flange for convenient connection to the snow removal roller brush 5. The rotation between the support plates 6 and the fixed shaft 1 is driven by a second hydraulic cylinder 7. The two second hydraulic cylinders 7 operate synchronously, driving the two support plates 6 to rise and fall synchronously, thereby driving the snow removal roller brush 5 to rise and fall independently.

[0034] The snow shovel 3 includes a snow shovel body 31. A connecting base 36 is fixedly attached to the bottom of the snow shovel body 31. A buffer base 32 is rotatably connected to the outer side of the connecting base 36. The buffer base 32 is designed to flip around the connecting base 36 when the bottom of the snow shovel 3 hits an obstacle, reducing the impact force on the snow shovel 3. An elastic pusher is provided between the buffer base 32 and the snow shovel body 31. The elastic pusher is used to provide a certain amount of thrust to the buffer base 32, ensuring its stability when pushing snow, and to push the buffer base 32 back into place after flipping.

[0035] The elastic pushing member includes a guide support rod 33 connected to both sides of the top of the buffer base plate 32, and the outer wall of the guide support rod 33 is sleeved with a compression spring 34. Guide ear plates 35 are fixed to the two hanging walls of the snow shovel body 31, and the guide support rod 33 passes through the guide ear plates 35, and the guide support rod 33 is slidably connected to the guide ear plates 35.

[0036] A linkage rotating plate 11 is provided at the bottom of the snowplow 3. This plate 11 primarily supports the snowplow 3, increasing its stability while pushing snow and reducing the force applied to the first hydraulic cylinder 4 during snowplowing. The two ends of the linkage rotating plate 11 are rotatably connected to the snowplow 3 and the snowplow roller brush housing 2, respectively. The end of the linkage rotating plate 11 connected to the snowplow roller brush housing 2 is coaxial with the end of the first hydraulic cylinder 4 connected to the snowplow roller brush housing 2.

[0037] Support shafts 9 are provided on both sides of the outer wall of the fixed shaft 1. A limiting nose bar 91 is fixedly connected to the outer wall of the support shaft 9. A support roller 8 is connected to the bottom of the support shaft 9. The support roller 8 is inserted into the inner side of the support shaft 9 and can rotate. The support roller 8 is used to support the fixed shaft 1. The wheel frame of the support roller 8 is provided with an arc-shaped limiting groove 81, which is coupled to the limiting nose bar 91. The limiting nose bar 91 can move horizontally within the limiting groove 81 to limit the rotation range of the support roller 8, preventing the support roller 8 from running under the snow removal roller 5. Long-term use will cause significant wear and tear on the snow removal roller 5.

[0038] An indicator light 10 is fixedly attached to the support plate 6 on one side. A pressure sensor is installed on the oil pipe of the drive motor of the snow removal roller 5. This pressure sensor is connected to a PLC controller, which controls the power on and off of the indicator light 10. When the snow removal roller 5 touches the ground, its rotation is obstructed, which increases the oil pressure in the oil pipe. The pressure sensor detects data and feeds this information back to the PLC controller, which controls the power on and off of the indicator light 10, controlling its brightness, and then feeding back the brightness signal to the operator in the cab.

[0039] The outer walls of both sides of the snow removal roller brush housing 2 are provided with guide grooves, and the inner walls of the two support plates 6 are provided with bumps that are slidably connected to the guide grooves to improve the stability of the support plates 6.
