Description

Technical Field

[0001] The invention relates to the technical field of snow-clearing brushes, in particular to a roller brush for clearing snow on roads. Background Art

[0002] The roller brush used for clearing snow on the road is generally connected to heavy vehicles such as large trucks, tractors or bulldozers. The power and traction of the vehicle are used to push and manipulate the roller brush, and the motor on the roller brush is used to drive it to rotate, so as to achieve the purpose of clearing snow on the road. During the process, the bristles of the roller brush will rub against the road surface. After long-term use, the length of the bristles will gradually shorten due to excessive wear, so that the height difference between the bristle end and the bottom of the cover shell gradually decreases. At the same time, it is easy to produce a large gap between the bristle end and the ground, affecting the contact area with the ground. Based on this, it will seriously affect the cleaning effect and efficiency of snow on the road. For this reason, the general solution is to uniformly replace the roller brushes used to clean snow on the road, but due to the high frequency of replacement, the replacement cost is relatively high.

[0007] Preferably, the conical component comprises a conical column whose diameter gradually increases from one side close to the connecting component to the other side, and an inclined slide groove having the same number as the connecting component is provided on the outer surface of the conical column, and a link structure is slidably connected between the inclined slide groove and the straight slide groove;

[0008] An embedded circular groove matched with the tail end of the adjusting screw is provided on the side of the conical column away from the connecting component, and the cross-section of the embedded circular groove is arranged in a T shape. A sealing groove plate is detachably installed on the end of the conical column away from the embedded circular groove.

[0009] Preferably, the link structure is composed of a lower shaft seat embedded in the inclined slide groove and an upper shaft seat embedded in the straight slide groove, and the lower shaft seat and the upper shaft seat are rotationally connected.

[0010] Preferably, the outer surface of the roller barrel is provided with a plurality of through grooves for inserting and assembling the fan-shaped brush body;

[0011] The outer surface of the roller cylinder is provided with a crushing assembly which is used to follow the rotation of the roller cylinder and be inserted obliquely downward into the snow.

[0012] Preferably, the crushing assembly includes a supporting steel frame installed on the outer surface of the roller cylinder, a transverse steel shovel is installed at one end of the supporting steel frame, a plurality of slots are opened on the transverse steel shovel, and the width of the slots is consistent with the width of the fan-shaped brush body, and a plurality of triangular steel blocks are integrally installed on the side of the transverse steel shovel close to the roller cylinder, and the triangular steel blocks are arranged at intervals from the slots.

[0013] Preferably, the fan-shaped brush body comprises an extended steel plate movably plugged on the roller barrel along the through groove, a fan-shaped block is installed at one end of the extended steel plate, a plurality of evenly arranged bristle strips are fixedly plugged on the fan-shaped block, and the plurality of bristle strips on the fan-shaped block are arranged in a fan shape.

[0014] Preferably, one end of the extended steel plate close to the connection assembly is integrally connected with a hole slot plate;

[0017] By means of the above technical solution, the present invention provides a roller brush for clearing snow from roads, which has at least the following beneficial effects:

[0018] 1. The present invention controls two conical components to move simultaneously toward the annular ring formed by a plurality of connecting components by synchronously rotating two adjusting screws, and as the conical components gradually move deeper into the annular ring, the plurality of connecting components can be forced to move outward, thereby expanding the annular ring formed by the plurality of connecting components, and achieving the purpose of extending the fan-shaped brush body outward, so as to compensate for the worn part when the bristle end of the outer side of the roller brush is worn and shortened, thereby extending the service life of the roller brush and reducing the replacement frequency.

[0019] 2. The present invention combines the conical column and the reinforcing steel bar through a connecting structure, which can effectively avoid the unstable phenomenon of internal and external swinging due to the rotation operation of the entire roller tube after the outer diameter of the fan-shaped brush body is adjusted in a circular arrangement.

[0020] 3. The present invention cooperates with the use of a crushing component sandwiched between the bristle strips. During the process in which the roller barrel rotates and drives the crushing component to rotate synchronously, the horizontal steel shovel in the crushing component will gradually tilt downward in some stages, and at the same time, it will generate an impact force and an oblique downward cutting force on the hard snow on the road surface, thereby achieving the purpose of crushing the hard snow. In addition, with a number of notches, the crushed hard snow can be dispersed in different directions, reducing the accumulation of snow on the horizontal steel shovel.

[0021] 4. After disassembling the expansion mechanism, the present invention pushes the corresponding connecting assembly toward one side, causing the several L-shaped structures on the reinforcing steel bar to be out of contact with the hole groove plates in the several fan-shaped brush bodies arranged in a horizontal row, so that the partial fan-shaped brush bodies in the entire roller brush can be disassembled and replaced conveniently, thereby effectively saving the overall replacement cost.

[0037] Embodiment 1

[0038] When a roller brush is cleaning snow on the road, its bristles will rub against the road surface, and the length of the bristles will gradually shorten due to excessive wear, so that the height difference between the bristle end and the bottom of the cover shell gradually decreases, and the contact area with the snow layer on the road is reduced, thus affecting the cleaning effect of the snow on the road. For this reason, the general solution is to uniformly replace the roller brushes used to clean snow on the road, but relatively speaking, the replacement cost is high and the service life of the roller brush is short.

[0039] To solve the problem of the bristles of the snow-clearing roller brush becoming shorter and needing to be replaced more frequently, please refer to Figure 1-Figure 8 This embodiment proposes a roller brush for clearing snow on the road. When the bristle end of the roller brush becomes visibly shorter, the bristles of the roller brush can be extended outward, thereby ensuring that the outer diameter of the roller brush is consistent with that when it is not in use, so as to ensure that the bristle end of the roller brush with shortened bristles can still contact the snow-covered ground during use. The roller brush has a roller barrel 1 and a plurality of fan-shaped brush bodies 2 plugged into the outer surface of the roller barrel 1. The fan-shaped brush bodies 2 are detachable from the roller barrel 1, so that when the bristles of a local area on the roller brush are damaged, a small-scale disassembly and replacement can be performed, thereby effectively saving the overall replacement cost. The interior of the roller drum 1 is provided with a plurality of connecting components 3 which are laterally plugged into a row of sector-shaped brush bodies 2, and the number of sector-shaped brush bodies 2 arranged in a ring shape is consistent with the number of connecting components 3. Expansion mechanisms 4 for increasing the outer diameter of the sector-shaped brush bodies 2 when the plurality of connecting components 3 are expanded in a ring shape are detachably installed at both ends of the roller drum 1. A protective cover 5 for protecting the rear side of the sector-shaped brush bodies 2 is rotatably connected between the two expansion mechanisms 4. A driving motor 6 installed on the outside of the protective cover 5 is used to drive the expansion mechanism 4 and the roller drum 1 to rotate. At the same time, a plurality of sector-shaped brush bodies 2 rotate synchronously, so that the bristles contact the snow on the road surface, thereby pushing away the accumulated snow and clearing it from the road surface. In addition, the centrifugal force of the rotation can throw the accumulated snow from the bristles to the side or rear of the snow-clearing brush, thereby forming a clear path. When assembling the fan-shaped brush body 2 and the roller tube 1, a plurality of fan-shaped brush bodies 2 are sequentially inserted into the roller tube 1 in a horizontal row, and then the corresponding connecting component 3 is placed into the interior of the roller tube 1, and is connected with the part of the fan-shaped brush body 2 in the horizontal row located inside the roller tube 1, and then the expansion mechanism 4 is assembled, so that the fan-shaped brush body 2 can be stably assembled on the roller tube 1.

[0040] Specifically, the connecting component 3 includes a reinforcing steel bar 301 arranged inside the roller cylinder 1, and a plurality of L-shaped structures 302 for plugging in the fan-shaped brush body 2 are integrally installed on the reinforcing steel bar 301. Straight sliding grooves 303 are provided on both sides of the surface of the reinforcing steel bar 301. The expansion mechanism 4 includes a head cylinder 401 which is detachably mounted on the end face of the roller cylinder 1 through a flange, and a hollow frame 402 is installed on the side of the head cylinder 401 away from the roller cylinder 1. A conical component 403 is provided inside the head cylinder 401, which is slidably connected to multiple reinforcing steel bars 301 through straight sliding grooves 303. An adjusting screw 404 is inserted into the middle thread on one side of the head cylinder 401 for controlling the conical component 403 to gradually increase the diameter of the ring surrounded by the multiple connecting components 3 when the conical component 403 moves horizontally along the head cylinder 401.

[0041] When in use, the conical component 403 is rotationally combined with the head cylinder 401 through the adjusting screw 404, and the conical component 403 is slidingly connected with multiple connecting components 3, and then the head cylinder 401 and the roller cylinder 1 are fixed by flanges and high-strength nuts. In the subsequent practical application, by synchronously applying a rotational force in a set direction to the adjusting screws 404 in the two expansion mechanisms 4, they are prompted to rotate along the outer wall of the head tube 401 toward the inside of the roller tube 1. During the rotation, the conical component 403 can be controlled to synchronously move toward the location of the connecting component 3. Since the diameter of the conical component 403 gradually increases from one side close to the connecting component 3 to the other side, as the conical component 403 penetrates into the annular ring formed by multiple connecting components 3, the connecting component 3 will move outward to adapt to the size of the conical component 403, and the inclined surface of the conical component 403 interacts with the connecting component 3, forcing the connecting component 3 to move outward and expand the annular ring formed by multiple connecting components 3, so as to achieve the purpose of extending the fan-shaped brush body 2 outward, thereby maintaining the position of the outer bristle end of the entire roller brush, ensuring that the bristle end of the entire roller brush can still contact the snow on the ground without changing its height, thereby improving the service life of the entire roller brush.

[0042] In order to effectively ensure that when the conical component 403 is moved laterally, the annular ring formed by the multiple connecting components 3 can be synchronously expanded outward or contracted inward. Figure 2-Figure 4 As shown, the conical component 403 includes a conical column 4031 whose diameter gradually increases from one side close to the connecting component 3 to the other side, and an outer surface of the conical column 4031 is provided with inclined slide grooves 4032 whose number is the same as that of the connecting component 3, and a link structure 4033 is slidably connected between the inclined slide grooves 4032 and the straight slide grooves 303, and an embedded circular groove 4034 adapted to the tail end of the adjusting screw 404 is provided on the side of the conical column 4031 away from the connecting component 3, and the cross-sectional surface of the embedded circular groove 4034 is T-shaped, and a sealing groove plate is detachably installed on the end of the conical column 4031 away from the embedded circular groove 4034, and the link structure 4033 is composed of a lower shaft seat embedded in the inclined slide groove 4032 and an upper shaft seat embedded in the straight slide groove 303, and the lower shaft seat and the upper shaft seat are rotatably connected. Pushing the conical column 4031 into the roller barrel 1 can generate an outward radial force on the multiple reinforcing steel bars 301, causing the diameter of the annular ring formed by the multiple reinforcing steel bars 301 to increase. During this process, the link structure 4033 enables the conical column 4031 and the reinforcing steel bars 301 to be connected, thereby effectively avoiding the instability of the inward and outward swinging due to the rotation of the entire roller barrel 1 after the outer diameter of the sector-shaped brush body 2 arranged in an annular circle is adjusted.

[0043] Before assembling the conical component 403 and the connecting component 3, the sealing plate and the conical column 4031 are in a disengaged state. During assembly, the sealing plate is placed in advance into the annular ring formed by multiple connecting components 3, and one end of the conical column 4031 is inserted into the annular ring. Then, the lower shaft seat in the linking structure 4033 is inserted into the end of the inclined groove 4032 opened on the surface of the conical column 4031. After that, the staff rotates the sealing plate into the gap between two adjacent connecting components 3 and inserts one end of the conical column 4031, thereby effectively preventing the linking structure 4033 from slipping out of the inclined groove 4032.

[0044] It should be emphasized that, in the present embodiment, the structure for driving the conical component 403 to move toward the annular circle formed by the plurality of connecting components 3 not only includes the adjusting screw 404, but also preferably a cylinder, an electric telescopic rod or other device with a telescopic function, in order to control the lateral movement of the conical component 403 relative to the connecting component 3.

[0045] Embodiment 2

[0046] As time goes by, the water in the snow on the road will gradually evaporate, and the loss of water will cause the snow to become dry and form ice crystals, making the texture of the snow hard. For hard snow, it is difficult to remove it by the rotation and friction of the bristles alone, and it will also cause serious wear of the bristles. In order to effectively clean the relatively hard snow, such as Figure 1 , Figure 6 and Figure 7As shown, the outer surface of the roller cylinder 1 is provided with a plurality of through grooves 101 for inserting and assembling the fan-shaped brush body 2. The outer surface of the roller cylinder 1 is provided with a crushing assembly 102 for following the rotation of the roller cylinder 1 and obliquely inserting into the snow downward. The crushing assembly 102 includes a supporting steel frame 1021 installed on the outer surface of the roller cylinder 1. A transverse steel shovel 1022 is installed at one end of the supporting steel frame 1021. The transverse steel shovel 1022 is provided with a plurality of notches 1023, and the width of the notches 1023 is consistent with the width of the fan-shaped brush body 2. The transverse steel shovel 1022 is integrally provided with a plurality of triangular steel blocks 1024 on one side close to the roller cylinder 1, and the triangular steel blocks 1024 are arranged at intervals from the notches 1023. When the rotating roller cylinder 1 drives the plurality of fan-shaped brush bodies 2 to rotate, the crushing assembly 102 rotates accordingly. When the transverse steel shovel 1022 in the crushing assembly 102 rotates to a position 45° below the front side of the roller cylinder 1, the tip of the transverse steel shovel 1022 faces downward. As it continues to rotate backward, the transverse steel shovel 1022 gradually tilts, and at the same time generates an impact force and a downward oblique cutting force on the hard snow on the road surface, thereby achieving the purpose of crushing the hard snow. Among them, the setting of the notch 1023 allows the crushed hard snow to be dispersed in different directions, reducing the accumulation of snow on the transverse steel shovel 1022 and improving the cleaning efficiency. And when the transverse steel shovel 1022 rotates, the sharp triangular steel block 1024 can pierce and break the frozen surface, making it easier to clear the snow.

[0047] In addition, the extension length of the fan-shaped brush body 2 can be controlled through the expansion mechanism 4 to adjust the spacing difference between the bristle end of the fan-shaped brush body 2 and the crushing component 102. When the crushing component 102 is needed, its tail end is close to the bristle end of the fan-shaped brush body 2. Otherwise, the crushing component 102 is buried inside several fan-shaped brush bodies 2.

[0048] Embodiment 3

[0049] When the roller brush used to clear snow on the road rotates to sweep the snow, if the snow in some areas is thicker or harder, the part of the roller brush that contacts these areas will be subjected to greater force, making the force on the roller brush as a whole uneven, resulting in excessive wear or damage to the roller brush, thus affecting the subsequent snow clearing effect. In general, this situation is solved by replacing the entire roller brush, but the replacement cost of this method is relatively high. Figure 1-Figure 4 , Figure 8As shown, in order to effectively reduce the cost of replacing damaged bristles of the roller brush, the fan-shaped brush body 2 includes an extension steel plate 201 movably plugged into the roller barrel 1 along the through groove 101, a fan-shaped block 202 is installed at one end of the extension steel plate 201, a plurality of uniformly arranged bristle strips 203 are fixedly plugged into the fan-shaped block 202, and the plurality of bristle strips 203 on the fan-shaped block 202 are arranged in a fan shape, a hole slot plate 204 is integrally connected to one end of the extension steel plate 201 close to the connection component 3, and the spacing between two adjacent L-shaped structures 302 on the reinforcing steel bar 301 is at least equal to the spacing between two adjacent hole slot plates 204 arranged transversely. When the fan-shaped brush body 2 and the roller barrel 1 are actually assembled, the extended steel plate 201 of the fan-shaped brush body 2 is inserted into the roller barrel 1 along the through groove 101, and then the reinforcing steel bar 301 is built into the space of the roller barrel 1, and one end of the plurality of L-shaped structures 302 is aligned with the circular hole on the hole groove plate 204, and then the reinforcing steel bar 301 is pushed toward one side, so that the plurality of L-shaped structures 302 can be respectively inserted into the plurality of hole groove plates 204 in a horizontal row. Then, the conical component 403 is slidably connected with the plurality of reinforcing steel bars 301, and the two conical components 403 on both sides of the roller barrel 1 are supported inside the two sides of the annular ring formed by the plurality of connecting components 3, so as to effectively maintain the length of the fan-shaped brush body 2 extending outward.

[0050] When it is necessary to replace a partial sector-shaped brush body 2, the flange and high-strength nut between the two head tubes 401 and the roller tube 1 are removed, and then the head tube 401 is rotated to cause it to rotate relative to the adjusting screw 404, so that a larger gap is generated between itself and the roller tube 1. Then the staff separates the sealing groove plate and the conical column 4031 in the conical component 403 in the gap between one of the head tubes 401 and the roller tube 1, and then pushes the corresponding connecting component 3 toward one side, causing several L-shaped structures 302 therein to be out of contact with the hole groove plates 204 in several sector-shaped brush bodies 2 arranged in a horizontal row. After that, the sector-shaped brush body 2 at the corresponding position in this horizontal row is taken out and the new sector-shaped brush body 2 is reinserted to complete the disassembly and replacement of the partial sector-shaped brush body 2.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
