Description

Technical Field

[0001] The utility model relates to a brush roller and a brush blade of a road ground snow sweeper, which is used for clearing snow on places such as road ground. Background Art

[0002] Snowplows mainly rely on the brush roller installed at the front of the vehicle to sweep and throw snow. The brush roller is installed at a certain angle to the snowplow, which is conducive to throwing snow to the roadside or piling it up for removal. The brush roller rotates at high speed under the action of power, sweeping the snow on the ground outward and throwing it to the side of the roadside, so that the road ahead of the snowplow is free of snow. The snowplow brush roller is composed of many brush blades assembled on the brush shaft. The snowplow brush blades are composed of brush wires, steel rings, and stop piles. The brush wires are evenly arranged in the circumferential direction and fixed in the outer groove of the steel ring. The steel ring is pressed and the brush wires are fixed. Then the side of the steel ring is pressed into a concave and convex shape or other shape through a mold to complete the brush blade production.

[0003] In the prior art, brush filaments are generally of the following three types: PP brush filaments, mixed brush filaments and pure steel wire brush sheets.

[0004] Among them, PP brush wire: the diameter of the brush wire is generally 2-3 mm, and multiple brush wires are folded in half and evenly fixed in the outer groove of the steel ring and pressed. The PP brush wire has good flexibility and can clean the unfrozen and thin snow on the ground. The PP brush wire wears out quickly due to friction in contact with the ground and is not wear-resistant. It needs to be replaced after one or two days of normal use.

[0005] Mixed brush wire: It is made of PP brush wire and corrugated steel wire with a diameter of about 0.8, folded in half and fixed in the outer groove of the steel ring. The mixed brush wire contains steel wire, which has high hardness and high elasticity. It can sweep thick snow and throw the snow to a farther place. Steel wire is more wear-resistant than PP brush wire and can appropriately increase its service life. However, a single steel wire is constantly swinging under the force during the snow sweeping process, and is prone to fatigue and breakage at the fixing point of the steel wire and the steel ring, and its service life is very short.

[0006] Pure steel wire brushes are generally made from 0.8mm corrugated steel wire, folded in half and evenly fixed in the outer groove of a steel ring. The steel wire is highly hard and elastic, capable of clearing thick or frozen snow and throwing it further. However, when clearing thick or frozen snow, pure steel wire brushes experience significant force on the bristles, causing them to constantly rebound and sway. The force is applied at the root of the wire where it meets the ring, and repeated swaying can lead to fatigue and breakage, resulting in a short service life.

[0007] The above three types of brush filaments and brush discs are very not durable. It is a huge expense for the sanitation department to purchase brush discs every year. In view of the above shortcomings, the present invention provides a better, more economical and durable solution. Utility Model Content

[0008] The purpose of the utility model is to provide a novel twisted filament snow brush blade, aiming to overcome the defects of the prior art and solve the problem that the three existing brush blades are very not durable.

[0009] To this end, the utility model proposes a new twisted wire bundle snow brush blade, comprising a steel ring outer groove, thick steel wire, a cylindrical retaining pile and a plurality of steel wire bundles; the middle part of the folded steel wire bundle is inserted into the inner side of the steel ring outer groove with a U-shaped cross-section, and a thick steel wire perpendicular to the middle part of the steel wire bundle is also provided, wherein the steel wire bundle is composed of a plurality of fine steel wires, and each bundle of the steel wire bundle comprises a straight section at a fixed end and a spiral section at a movable end, and the fine steel wires of the spiral section are wound together in a spiral manner.

[0010] As a preferred technical solution of the present application, the end of the spiral segment is not completely clamped, so that the outer end of the spiral segment forms an end spread segment, and the thin steel wire of the end spread segment is straight or slightly arc-shaped.

[0011] As a preferred technical solution of the present application, the total length of the steel wire bundle before folding into a U shape is 300mm-550mm, and the length can be adjusted according to actual needs.

[0012] As a preferred technical solution of the present application, the total length of the straight section is 25mm~40mm.

[0013] As a preferred technical solution of the present application, the thin steel wire is a cylindrical steel wire with a diameter of 0.5~0.8mm.

[0014] As a preferred technical solution of the present application, each bundle of the steel wires includes 20 to 65 fine steel wires.

[0015] As a preferred technical solution of the present application, a large number of locking grooves are processed on the left and right side walls of the steel ring outer groove, and the locking grooves are recessed toward the inner side of the steel ring outer groove; the locking grooves are evenly distributed along the length direction of the steel ring outer groove.

[0016] As a preferred technical solution of the present application, a plurality of steel wire bundles extend along the radial direction of the arc where the outer groove of the steel ring is located.

[0017] As a preferred technical solution of the present application, the outer groove of the steel ring after forming is a three-dimensional annular structure.

[0018] As a preferred technical solution of the present application, the connection of the outer groove of the steel ring is fixed by a cylindrical retaining pile.

[0019] The new twisted wire bundle snow-clearing brush blade provided by the present invention uses a steel wire bundle to replace a single steel wire and a PP brush wire, which is evenly fixed and pressed into the outer groove of a steel ring to form a brush blade; the advantages of a twisted steel wire bundle over a single steel wire and a PP brush wire are: 1. The steel wire has a small diameter, and the steel wire at its end is spread out, which has a better contact surface and can better sweep up the snow, making the ground cleaner. 2. The steel wire is twisted into a bundle, which has stronger elasticity and better snow throwing effect, and can shovel frozen snow or thicker snow. 3. The steel wire is twisted into a bundle and fixed in the steel ring, and the stress fatigue point of the single steel wire is not at the place where it is fixed to the steel ring. The steel wire bundle can well overcome the fatigue fracture of the steel wire, making the steel wire very wear-resistant. In the case of no fatigue fracture, the service life can reach several months. 4. The increase in service life greatly reduces the economic expenditure of the sanitation department in purchasing brush blades.

[0020] In addition to the above-described purposes, features and advantages, the present application also has other purposes, features and advantages. The present application will be further described in detail below with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] like Figures 1 to 3As shown, the new twisted wire bundle snow brush blade of the present invention includes: a steel ring outer groove 1, a thick steel wire 2, a cylindrical retaining pile 3 and a plurality of steel wire bundles 4; the middle part of the folded steel wire bundle 4 is inserted into the inner side of the steel ring outer groove 1 with a U-shaped cross-section, and a thick steel wire 2 perpendicular to it is also provided in the middle part of the steel wire bundle 4. The plurality of steel wire bundles 4 extend along the radial direction of the arc where the steel ring outer groove 1 is located, and the folded steel wire bundle 4 is pressed and fixed by the thick steel wire 2 and the steel ring outer groove 1 with a U-shaped cross-section.

[0028] Among them, the connection of the steel ring outer groove 1 is fixed by a cylindrical retaining pile 3. The formed steel ring outer groove 1 has a three-dimensional ring structure. The cylindrical retaining pile 3 can also fix the brush piece on the brush shaft and will not rotate circumferentially.

[0029] At the same time, a large number of locking grooves 5 are processed on the left and right side walls of the steel ring outer groove 1. The locking grooves 5 are evenly distributed along the length direction of the steel ring outer groove 1, and the locking grooves 5 are recessed toward the inner side of the steel ring outer groove 1, further clamping and fixing the steel wire bundle 4 to prevent the steel wire bundle 4 from shaking or falling.

[0030] Specifically, the steel wire bundle 4 is composed of several fine steel wires. Each steel wire bundle 4 includes a straight section 41 at a fixed end and a spiral section 42 at a movable end. The fine steel wires in the spiral section 42 are twisted together in a spiral manner to prevent direct stress on the base of a single steel wire and fatigue breakage at the base of a single fine steel wire. The fine steel wires in the straight section 41 are arranged in parallel so as to be flattened and folded into a U-shape. During the processing of the steel wire bundle 4, the ends of the spiral sections 42 are not fully clamped, resulting in a splayed section 43 at the outer ends of the spiral sections 42. The fine steel wires in the splayed section 43 are straight or slightly arc-shaped.

[0031] Furthermore, each steel wire bundle 4 comprises approximately 20 to 65 fine steel wires, resulting in a diameter of 3 to 5 mm. These fine steel wires are typically cylindrical with a diameter of 0.5 to 0.8 mm. The total length of the cylindrical wires ranges from 300 to 550 mm, and the length can be adjusted based on actual needs. Compared to irregular, wavy wires, cylindrical fine steel wires are easier to entangle during the twisting process. After the cylindrical wires are twisted, the total length of the straight section 41 is 25 to 40 mm, matching the width of the steel coil. A standard-sized steel wire bundle 4 has a total length of approximately 450 mm, with the straight section 41 being approximately 30 mm long. The diameter of the steel wire bundle 4 is approximately 4 mm.

[0032] In this embodiment, a fixed stop bar is installed on the snowplow's brush shaft. Two cylindrical stoppers are installed in the inner hole of the snowplow's brush blade. The two stoppers are locked into the stop bar, securing the brush blade to the brush shaft and preventing radial rotation. Stop rings are installed at both ends of the brush shaft. After the brush blade is installed, the stop rings are fixed in place to prevent the brush blade from sliding axially.

[0033] The following is a brief description of the manufacturing process of the new twisted wire snow brush blade of the utility model:

[0034] S1. Clamp the middle position of multiple thin steel wires appropriately; S2. Rotate the twisting rods at both ends to twist the unclamped parts of the thin steel wires into steel wire bundles, with the ends spread out; S3. Loosen the clamping device to obtain a straight section in the middle, with steel wire bundles twisted into bundles on both sides and spread out at the ends; S4. Lay the outer groove of the steel ring on a horizontal workbench, lay a large number of steel wire bundles perpendicular to the outer groove of the steel ring evenly, and place a thick steel wire on it; S5. Start the motor and drive the outer groove of the steel ring to move forward, and press it into the turntable with a U-shaped groove to form a disc-shaped or sheet-shaped wire brush piece; finally, use a stamping die to press the steel wire brush piece with a circular inner ring into a three-dimensional ring structure.

[0035] The new twisted wire bundle snow brush blade of the present invention uses a steel wire bundle to replace a single steel wire and PP brush wire, which is evenly fixed and pressed into the outer groove of the steel ring to form a brush blade. The advantages of a twisted wire bundle over a single steel wire and PP brush wire are: 1. The diameter of the steel wire is small, and the steel wire at its end is spread out, which has a better contact surface and can better sweep up the snow, making the ground cleaner. 2. The steel wire is twisted into a bundle, which has stronger elasticity and better snow throwing effect, and can shovel frozen snow or thicker snow. 3. The steel wire is twisted into a bundle and fixed in the steel ring. The stress fatigue point of the single steel wire is not at the place where it is fixed to the steel ring. The steel wire bundle can overcome the fatigue fracture of the steel wire very well, making the steel wire very wear-resistant. In the case of no fatigue fracture, the service life can reach several months. 4. The increase in service life greatly reduces the economic expenditure of the sanitation department in purchasing brush blades.

[0036] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
