Description

Technical Field

[0001] This utility model relates to the field of snow sweeping roller technology, and in particular to a snow sweeping roller structure. Background Technology

[0002] A snowplow roller is a large rotating roller installed at the front, side, or rear of a vehicle (such as a truck, tractor, loader, or special snowplow) or small equipment (such as a push snowplow). The roller is densely covered with bristles, which consist of metal rings and retaining pins. The retaining pins are fixed to the roller for installation.

[0003] The roller brush cylinder is usually installed after the brush blades are installed and then the roller brush cover is installed. At this time, the roller brush cylinder is relatively heavy, and the shafts on both sides need to be aligned with the shaft holes on the inner wall of the roller brush cover before it can be installed. This process requires precise adjustment with the help of an external carrier, which is time-consuming and labor-intensive.

[0004] Secondly, the connection between the roller brush and the external motor is a rigid connection. When the motor starts suddenly, the heavy roller brush, if not dynamically balanced, can easily cause serious damage to the motor shaft, which is not conducive to the safe use of the motor.

[0005] To address the above problems, a snow-sweeping roller structure is proposed. Utility Model Content

[0006] The main purpose of this utility model is to provide a snow sweeping roller structure that solves the problems mentioned in the background art.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A snow sweeping roller structure includes a central shaft, a roller structure disposed outside the central shaft, four sets of square tubes welded and fixed to the outer peripheral wall of the roller structure, round tubes integrally welded to both ends of the square tubes, side covers welded to both ends of the roller structure, and a plurality of sweeping brush blade bodies sleeved on the outside of the square tubes.

[0009] A flexible coupling that can be detachably installed with the side cover is provided directly below the circular tube.

[0010] Furthermore, the roller structure comprises several plates, the center of which is welded through by the central shaft, and the outer peripheral wall of the plate is welded to the contact surface of the square tube.

[0011] Furthermore, the roller structure is a cylinder, the center of which is welded through by the central shaft, and the outer peripheral wall of the cylinder is welded to the contact surface of the square tube.

[0012] Furthermore, the inner wall of the circular tube is threaded and a locking screw can be detachably installed.

[0013] Furthermore, the elastic coupling includes an elastic body, the outer peripheral wall of which has four sets of radial holes perpendicular to the shaft core, and the two outer walls of the elastic body have four sets of through axial holes.

[0014] Furthermore, the side cover has four sets of through mounting holes, which are aligned with the axial holes.

[0015] Furthermore, the brush blade body includes a metal ring that is slidably installed with the square tube, and a retaining shaft located on both sides of the square tube is integrally welded to the inner wall of the metal ring. An interlayer bushing that is slidably installed with the outer wall of the square tube is pressed between adjacent brush blade bodies.

[0016] Furthermore, a shaft connector is provided in the inner cavity of the elastic coupling, and the shaft connector is detachably installed with the elastic coupling through the radial hole.

[0017] The beneficial technical effects of this utility model are as follows:

[0018] This invention features flexible couplings at both ends of the roller brush cylinder, with shaft connectors installed inside the flexible couplings. The flexible couplings are fixedly connected to the side cover of the roller brush cylinder through axial holes, and the flexible couplings are fastened to the shaft connectors through radial holes. This installation method allows the shaft connectors and the two through holes of the outer cover to pass through and be installed separately under the elastic action of the elastic body, without the need for concentric alignment, thus saving installation work. At the same time, the elastic action of the elastic body is used to prevent the motor shaft from being damaged by the unbalanced force when the roller brush cylinder starts and stops.

[0019] This invention, by setting up four sets of square tubes, further improves the dynamic balance of the roller brush when it rotates, compared to the traditional two sets of square tubes on the roller brush, which is conducive to the stable snow sweeping of the roller brush.

[0027] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0028] like Figures 1-5 As shown, the snow sweeping roller structure provided in this embodiment includes a central shaft 5, a roller structure is provided on the outside of the central shaft 5, four sets of square tubes 2 are welded and fixed on the outer peripheral wall of the roller structure, round tubes 9 are integrally welded to both ends of the square tubes 2, side covers 6 are welded to both ends of the roller structure, and a plurality of brush blade bodies 3 are sleeved on the outside of the square tubes 2; an elastic coupling 7 that can be detachably installed with the side covers 6 is provided directly below the round tubes 9.

[0029] In the above structure, the traditional roller structure only has two sets of square tubes 2, while the four sets of square tubes 2 in this application can improve the dynamic balance when the roller rotates at high speed.

[0030] The roller structure consists of several plates 1, with the center of each plate 1 welded through by a central shaft 5, and the outer peripheral wall of each plate 1 welded to the contact surface of the square tube 2.

[0031] In this embodiment, the design of the web plate 1 reduces the weight of the roller, making the brush roller lighter.

[0032] The roller structure is a cylinder 11, the center of which is welded through by the central shaft 5, and the outer peripheral wall of the cylinder 11 is welded to the contact surface of the square tube 2.

[0033] In this embodiment, the structure of the cylinder 11 provides better dynamic balance than the structure of the web plate 1, but it has a larger weight.

[0034] The inner wall of the round tube 9 is threaded and can be detachably fitted with a locking screw 8. The locking screw 8 can be pre-locked at one end, and the brush blade body 3 is sequentially installed onto the square tube 2.

[0035] The flexible coupling 7 includes an elastic body 701. The outer peripheral wall of the elastic body 701 has four sets of radial holes 703 perpendicular to the shaft core. The outer walls on both sides of the elastic body 701 have four sets of through axial holes 702. The elastic body 701 is a rubber pad with good elasticity. When installed aligned with the side cover, it can quickly install the shafts on both sides through a small deformation, thus improving installation efficiency.

[0036] The side cover 6 has four sets of through side cover mounting holes 601, which are aligned with the axial holes 702.

[0037] The brush blade body 3 includes a metal ring 301 that is slidably installed with the square tube 2. The inner wall of the metal ring 301 is integrally welded with retaining pins 302 located on both sides of the square tube 2. Between adjacent brush blade bodies 3, there is a sandwich liner 4 that is slidably installed with the outer wall of the square tube 2. The purpose of the retaining pins 302 is to limit the brush blades when rotating at high speed. The adjacent brush blades are installed crosswise, which has good dynamic balance when rotating.

[0038] The flexible coupling 7 has a shaft connector 10 in its inner cavity. The shaft connector 10 is detachably installed with the flexible coupling 7 through the radial hole 703. The shaft connector 10 is connected to the external motor shaft by a key.

[0039] The working principle of this device is as follows:

[0040] During installation, the device first inserts the elastic coupling 7 into the round tube 9 and secures it with bolts through the axial hole 702 and the side cover mounting hole 601 on the side cover 6. It is then fixedly connected to the internal shaft connector 10 through the radial hole 703. Next, a locking screw 8 is screwed into the round tube 9 at one end. The brush body 3 slides into the square tube 2 along one end of the round tube 9 through the retaining shaft 302. A sandwich bushing is placed between adjacent brush bodies 3. When adjacent brush bodies slide into the square tube 2, the retaining shaft 302 is symmetrically positioned. The metal ring 301 of the brush body 3 presses against the inside of the locking screw 8. This method can be used to continue installing the brush body 3 to the other side until it reaches the end of the round tube 9 on the other side. Similarly, the locking screw 8 is used to press and fix the brush body 3. The shaft connector 10 can be aligned with the shaft hole passing through the outer cover and connected to the external motor shaft key.

[0041] The above structure allows the side cover and the roller brush to be installed without concentric alignment, saving installation work. At the same time, the elasticity of the elastomer 701 is used to prevent the unbalanced force of the roller brush cylinder from damaging the motor shaft during start-up and shutdown.

[0042] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0043] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
