Description

Technical Field

[0001] The utility model belongs to the technical field of snow removal roller brushes, in particular to a segmented roller core of a snow removal roller brush. Background Art

[0002] With the development of 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 roller brushes to clear snow. Traditional snow removal roller brushes use single-sided drive roller brushes. Single-sided drive causes uneven force on the roller brush, small roller brush driving torque, low speed, and low snow removal efficiency. To solve this problem, there is also a double-sided power-driven snow removal roller brush, which has the advantages of large driving torque and high speed.

[0003] However, the roller core of existing snow removal roller brushes is mostly a whole roller core structure. Due to the long roller core and the asynchronous power drive on both sides, on the one hand, the vibration amplitude of the roller brush during the snow removal operation is greatly increased, which makes the overall stability of the roller brush operation drop sharply and the snow removal effect is not ideal; on the other hand, the vibration of the snow roller brush will cause damage to related drive components, shortening their service life and reducing their reliability, resulting in a small application range of the snow removal roller brush and inability to cope with snow removal operations in multiple scenarios. Therefore, it is necessary to develop an optimized snow removal roller brush. Utility Model Content

[0004] In order to solve the technical problems existing in the prior art, the present application provides a segmented roller core of a snow removal roller brush which adopts a segmented roller core to improve the synchronization during double-sided transmission and reduce the jumping of the roller core during working rotation and has a simple structure and is easy to disassemble and assemble.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A segmented roller core of a snow removal roller brush comprises a roller core, wherein two roller cores are provided and opposite ends thereof are rotatably connected to an intermediate transition assembly respectively, and the intermediate transition assembly is fixedly connected to a roller brush frame; the other ends of the two roller cores which are separated from each other are coaxially fixedly connected to one end of a half-shaft, a sprocket is fixedly sleeved on the other end of the half-shaft, a first bearing is fixedly sleeved on the half-shaft between the roller core and the sprocket, and the first bearing is fixedly connected to the roller brush frame.

[0007] Preferably, the intermediate transition assembly includes a pull plate fixedly connected to the roller brush frame, a second bearing fixedly connected to the end faces of both sides of the pull plate, a coupling with a rotating portion at one end fixedly inserted in the second bearing, and a connecting portion at the other end of the coupling inserted in the roller core and the coupling and the roller core cannot rotate relative to each other.

[0008] Preferably, the roller core includes a roller shaft, a connecting disk fixedly connected to one end of the roller shaft, a connecting sleeve fixedly connected to the other end of the roller shaft, a connecting plate fixedly connected to the outer circumference of the roller shaft, a connecting shaft fixedly connected to the connecting plate, and connecting rings fixedly connected at both ends of the connecting shaft, the connecting disk is fixedly connected to the half shaft, and the connecting portion of the coupling is inserted into the connecting sleeve.

[0009] Preferably, the connecting portion of the coupling is an external hexagonal structure and the inside of the connecting sleeve is a matching internal hexagonal structure.

[0010] Preferably, a limiting portion is fixedly connected on the outer circumference between the rotating portion and the connecting portion of the coupling, and the connecting sleeve and the second bearing opposite thereto are respectively arranged on both sides of the limiting portion.

[0011] Preferably, a connecting flange is provided at one end of the half shaft, and the connecting plate is fixedly connected to the connecting flange by bolts.

[0012] Preferably, a first step and a second step are provided on the half-shaft, a first bearing and a spacer sleeve are sequentially sleeved on the first step, a sprocket is sleeved on the second step, and the fastening bolts are passed through the sprocket cover and threadedly connected to the end of the half-shaft to fix the first bearing, the spacer sleeve and the sprocket on the half-shaft.

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

[0014] The segmented roller core of the utility model is not only fixedly mounted on the roller brush frame by the first bearings and bolts at both ends, but the intermediate transition assembly in the middle of the segmented roller core is also connected to the roller brush frame, thereby ensuring that the overall connection of the segmented roller core is firm and reliable; the roller core of the utility model adopts a segmented structure, and the roller core can rotate independently after segmentation. Compared with the existing single roller core structure, the coaxiality of the roller core is easy to ensure, which reduces the vibration of the roller brush during operation, greatly reduces the vibration of the roller core during working rotation, and ensures the overall stability of the roller brush, thereby improving the snow removal efficiency and widening the application range. In addition, the segmented roller core of this snow removal roller brush has a simple structure and is easy to disassemble and assemble, which can reduce the production cost and has certain practical and promotion value.

[0015] In addition, during the actual production and application process, the length of each roller core can be adjusted according to the snow removal needs to equip roller brush frames of different lengths. The snow roller brushes on both sides drive the sprockets at both ends of the segmented roller core to rotate through chains, thereby realizing the synchronous rotation of both sides of the snow roller brush core to perform snow removal operations, ensuring the coaxiality of the snow roller brush core, reducing the vibration of the snow roller brush during rotation, and improving the stability of the snow roller brush.

Example

[0026] See also Figure 1 ,2 As shown in Figure 3, a segmented roller core of a snow removal roller brush comprises a roller core 1, wherein the roller core 1 is provided with two roller cores, and the opposite ends thereof are respectively rotatably connected to the intermediate transition assembly 2, and the intermediate transition assembly 2 is fixedly connected to the roller brush frame (not shown in the figure). The other ends of the two roller cores 1 that are separated from each other are coaxially fixedly connected to one end of the half shaft 3, and a sprocket 4 is fixedly sleeved on the other end of the half shaft 3, and a first bearing 5 is fixedly sleeved on the half shaft 3 between the roller core 1 and the sprocket 4, and the first bearing 5 is fixedly connected to the roller brush frame. Therefore, through the above structure, the existing double-sided power unit can drive the sprockets 4 on both sides to rotate, thereby driving the corresponding roller core 1 to rotate respectively, and installing a roller brush sheet (not shown in the figure) on the roller core 1 can drive the roller brush sheet to rotate, thereby realizing the synchronous rotation of both sides of the roller core 1 to perform snow removal operations, improving the coaxiality of the roller core 1, reducing the jumping of the snow removal roller brush during the rotation process, and improving the stability of the snow removal roller brush. In addition, in the above structure, the two segmented roller cores 1 are fixedly mounted on the roller brush frame through the first bearing 5 and the intermediate transition assembly 2, respectively, so as to ensure that the overall connection of the segmented roller core 1 is firm and reliable.

[0027] Specifically, each section of the roller core 1 includes a roller shaft 11, a connecting disk 12 fixedly sleeved on one end of the roller shaft 11 by interference fit or welding, a connecting sleeve 13 fixedly sleeved on the other end of the roller shaft 11 by interference fit, welding or bolting, a plurality of evenly distributed connecting plates 14 fixedly sleeved on the outer circumference of the roller shaft 11 by welding, a plurality of connecting shafts 15 welded on the outer end faces of the connecting plates 14, and connecting rings 16 fixedly connected at both ends of the connecting shafts 15 by bolts. In the present embodiment, three connecting shafts 15 are evenly distributed along the outer circumference of the roller shaft 11 and are parallel to the axis of the roller shaft 11, a roller brush piece can be fixedly mounted on the connecting shaft 15, and the connecting ring 16 is arranged on the outer sides of the corresponding connecting sleeves 13 and connecting disks 12.

[0028] See also Figure 7 As shown, specifically, a connecting flange 31 is integrally formed at one end of the half shaft 3, and the connecting plate 12 is fixedly connected to the connecting flange 31 by bolts, so that the half shaft 2 and the roller core 1 are fixedly installed together. In order to facilitate the installation of the first bearing 5 and the sprocket 4 and to limit the two, as shown in FIG. Figure 7The half shaft 3 shown is provided with a first step 32 and a second step 33 from left to right, and the first bearing 5 and the spacer 6 are sleeved on the first step 32, and the sprocket 4 is sleeved on the second step 33. In order to facilitate the installation and fixation of the sprocket 4, the fastening bolts 41 are inserted into the sprocket pressure cover 42 and threadedly connected to the end of the half shaft 3. Through this structure, the two end surfaces of the inner ring of the first bearing 5 are respectively abutted and tightened against the first step 32 and the spacer 6, and the two end surfaces of the sprocket 4 are respectively abutted and tightened against the spacer 6 and the sprocket pressure cover 42, thereby fixing the first bearing 5, the spacer 6 and the sprocket 4 on the half shaft 3. In order to make the half shaft 3 rotate smoothly and fix the half shaft 3 on the roller brush frame, the bearing seat corresponding to the first bearing 5 is fixedly installed on the roller brush frame by bolts.

[0029] See also Figure 4 , 5 As shown in Figures 6 and 7, the intermediate transition assembly 2 includes a pull plate 21 fixedly connected to the roller brush frame by bolts, and connecting bosses 211 are integrally formed with the pull plate 21 on both side end surfaces of the pull plate 21, and bearing seats are fixedly connected to the end surfaces of the two connecting bosses 211 by bolts, and a second bearing 22 is installed in the bearing seat, and a coupling 23 is penetrated in each second bearing 22. Specifically, the coupling 23 includes a rotating part 231, a connecting part 232 integrally formed and coaxially arranged with the rotating part 231, and a fixedly connected limiting part 233 integrally formed on the outer circumference between the rotating part 231 and the connecting part 232.

[0030] The rotating part 231 of the coupling 23 is a cylindrical structure and is installed in the inner ring of the second bearing 22 by transition fit, and the limiting part 233 abuts against the inner end face of the second bearing 22 opposite thereto. The connecting part 232 of the coupling 23 is inserted into the connecting sleeve 13 of the roller core 1, and the coupling 23 and the roller core 1 cannot rotate relative to each other, so that the power unit can drive the roller core 1 and the coupling 23 to rotate in sequence. In order to facilitate the axial rotation limiting of the coupling 23 and to facilitate the connection part 232 to be inserted into the connecting sleeve 13, in the present embodiment, the connection part 232 of the coupling 23 is an external hexagonal structure and the connecting sleeve 13 is an internal hexagonal structure matching the connection part 232. In addition, the end surface of the limiting part 233 opposite to the connecting sleeve 13 abuts against the end surface of the connecting sleeve 13, and a gap is provided between the two opposite connection parts 232 of the two couplings 23, that is, the driving units on both sides can drive the roller core 1 and the coupling 23 on the corresponding side to rotate independently, thereby solving the problems of low coaxiality of the roller brush, increased vibration amplitude of the roller brush, low reliability and small application range of the entire roller core structure due to the long roller core and asynchronous power drive on both sides.

[0031] Thus, through the above structure, the roller core 1 is a segmented structure and the two roller cores 1 are symmetrically arranged on the intermediate transition assembly 2. In addition, the two sets of second bearings 22, the connecting boss 211, and the coupling 23 of the intermediate transition assembly 2 are also symmetrically arranged, which can further improve the stability of the roller core 1 during rotation. In addition, in this embodiment, the first bearing 5 and the second bearing 22 can both use a self-aligning bearing structure.

[0032] The working process of the embodiment of the utility model is as follows:

[0033] According to the above description of the specific structure and connection relationship of each component, the segmented roller core of the snow removal roller brush is installed, such as Figure 1 As shown, the pull plate 21 and the first bearing 5 are fixedly installed on the roller brush frame by bolts, so that the entire roller core 1 is installed on the roller brush frame through the pull plate 21 and the first bearing 5; the power unit drives the sprocket 4 to rotate through the chain, thereby driving the roller core 1 to rotate in the first bearing 5 and the second bearing 22; when a power unit with double-sided power output is selected, the sprockets 4 and the roller core 1 at both ends can be driven to rotate synchronously at the same time, so as to realize the double-sided synchronous rotation of the roller core 1 and perform snow removal operations through the roller brush piece installed on the roller core 1. In this process, the coaxiality of the entire roller core structure of the snow removal roller brush is further improved, the jumping of the snow removal roller brush during rotation is reduced, and the stability of the snow removal roller brush is improved.
