Description

Technical Field

[0001] This utility model relates to the field of snow removal tools, and in particular to a snow brush shovel that combines chiseling and scraping functions. Background Technology

[0002] A snow shovel is a tool specifically designed for snow and ice removal, combining the functions of a snow shovel and a snow brush. A standard snow shovel has a hard plastic shovel at the front for removing accumulated snow, and a soft-bristled snow brush on the side for sweeping away surface snow or residual snow. However, in cold climates, snowfall is usually accompanied by icing. When ice forms at the bottom of the snow layer, a standard snow shovel can effectively clear the surface snow, but it lacks the impact force to break the ice and effectively remove the hard ice at the bottom. In such cases, people must use external tools to break the ice first, and then use a standard snow shovel to clear away the broken ice and residual snow. This method is not quick or convenient, affecting the efficiency of snow and ice removal. Utility Model Content

[0003] To overcome the technical problem of poor de-icing effect in the existing technology, this utility model provides a snow scraper that integrates chiseling and scraping functions.

[0004] To achieve the above objectives, this utility model proposes a snow scraper with integrated chisel and scraping functions, including a handle with a brush and a scraper head at each end. The scraper head is rotatably connected to the handle, and a chisel head assembly is provided at the end of the handle with the scraper head. The chisel head assembly includes a connector and a chisel head. The connector is fixedly connected to the handle, and the chisel head is detachably connected to the connector. A boss is provided on the connector corresponding to the position of the chisel head. Multiple symmetrically distributed footplates are provided on the handle corresponding to the position of the chisel head assembly.

[0005] Furthermore, the connector has a second positioning groove for engaging the chisel head at one end near the boss. The second positioning groove has multiple evenly distributed magnetic blocks inside, which attract the chisel head into the second positioning groove.

[0006] Furthermore, the chisel head includes a cutting edge and a chisel body; the chisel body is fixedly connected to the connecting piece. The cutting edge is provided with multiple evenly spaced raised ridges.

[0007] Furthermore, the chisel body is provided with multiple through holes, which are distributed radially along the direction from the chisel body to the cutting edge.

[0008] Furthermore, the grip includes an upper telescopic joint, a connecting rod, and a lower telescopic joint. Both ends of the connecting rod are provided with threaded rods, and both the upper and lower telescopic joints are provided with internally threaded cylinders that mate with the threaded rods.

[0009] Furthermore, the handle is provided with platforms on both sides corresponding to the shovel head, and each platform on both sides of the handle is provided with a round hole. Each side of the shovel head is provided with a frustum that matches the round hole.

[0010] Furthermore, the platform on both sides of the handle has a first side edge and a second side edge that are perpendicular to each other. The circular hole has a first positioning hole and a second positioning hole in its circumferential direction, and the shovel head has a positioning screw. When the positioning screw is engaged with the first positioning hole, the shovel head is in contact with the first side edge; when the positioning screw is engaged with the second positioning hole, the shovel head is in contact with the second side edge.

[0011] Furthermore, the shovel head includes a bucket and a swing arm, with symmetrically distributed swing arms on the bucket. One end of the swing arm is fixedly connected to the bucket, and the other end is rotatably connected to the handle.

[0012] Furthermore, a damping shaft is provided at the end of the handle away from the shovel head, and the brush is rotatably connected to the handle via the damping shaft. A knob is provided on the damping shaft to control the rotation angle of the brush.

[0013] The beneficial effects of this invention are as follows: When the shovel head is rotated to be perpendicular to the handle, the chisel head at the end of the handle is exposed, allowing for impact and breaking of the ice. During ice removal, the shovel head, perpendicular to the handle, provides some protection, preventing ice fragments from flying onto the user. The shovel head can also be used to scrape away ice debris. When the chisel head penetrates the ice, the user can use the protrusion as a fulcrum and apply sufficient torque to the ice through the handle, facilitating ice breaking. The user can also apply external force to the footplate to increase the impact force of the chisel head on the ice, improving the efficiency of ice removal. Attached Figure Description

[0024] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0025] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-7 As shown, this utility model proposes a snow scraper with integrated scraping function, including a handle 1, with a brush 2 and a scraper head 3 at each end. The handle 1 is made of aerospace-grade aluminum alloy or carbon fiber composite material to reduce its weight while ensuring its strength. A cushioning pad 14 is covered on the handle 1. The cushioning pad 14 is made of thickened rubber cotton or high-density sponge and rubber composite cotton layer to improve the user's comfort when holding the handle 1. The surface of the cushioning pad 14 is designed with biomimetic anti-slip grooves with a groove depth of 0.8mm-1.2mm and a spacing of 3mm. Micron-sized silicone particles are embedded inside the biomimetic anti-slip grooves, which can maintain a high coefficient of friction even in an environment with 50% humidity, reducing the risk of slippage when the user operates the snow scraper. The user can use the scraper head 3 to remove snow, thin ice, or other debris, and then use the brush 2 to further clean up any remaining debris.

[0027] The shovel head 3 is rotatably connected to the handle 1. The handle 1 has a chisel assembly 4 at one end where the shovel head 3 is located. Rotating the shovel head 3 exposes the chisel assembly 4, allowing for quick switching between snow shoveling and ice-breaking functions without disassembling the entire tool, improving operational efficiency and facilitating ice breaking by the user operating the chisel assembly 4 on the handle 1. The chisel assembly 4 is hidden behind the shovel head 3, improving the device's integration and minimizing its storage space, making it easy to carry and store. The chisel assembly 4 includes a connector 41 and a chisel head 42. The connector 41 is fixedly connected to the handle 1, while the chisel head 42 is detachably connected to the connector 41. The end of the handle 1 has a first positioning groove 112 that engages with the connector 41. One end of the connector 41 is embedded in the first positioning groove 112, and a fixing screw 113 is located at the first positioning groove 112 on the handle 1. The fixing screw 113 passes through the side wall of the first positioning groove 112 and is screwed into the threaded hole 411 on the connector 41, thus fixing the chisel assembly 4 to the handle 1.

[0028] The connector 41 has a second positioning groove 413 near the boss 412, which engages with the chisel head 42. Multiple evenly distributed magnetic blocks 4131 are located within the second positioning groove 413, attracting the chisel head 42 into the groove. The magnetic blocks 4131 are typically high-magnetic neodymium iron boron magnets, providing sufficient magnetic force to ensure the chisel head 42 does not fall off during operation. Compared to traditional bolts or clips, magnetic attraction may be more convenient for users to replace or adjust the chisel head 42, improving efficiency. Even if individual magnetic blocks 4131 fail due to low-temperature demagnetization (e.g., a decrease in magnetic permeability of approximately 30% at -30℃), the remaining magnetic blocks 4131 can still maintain the connection of the chisel head 42 through distributed attraction. As a consumable part, the chisel head 42 may experience dulling, bending, and deformation after long-term use. The requirements for the chisel cutting edge 421 vary depending on the ice thickness. When dealing with thin ice, the sharp-edged chisel 421 can quickly break the ice layer; when dealing with thick ice, the blunt-edged chisel can apply greater impact potential energy to break the ice layer. Therefore, the detachable chisel head 42 can maintain the ice-breaking effect of the chisel head assembly 4 according to actual needs. The connector 41 has a boss 412 corresponding to the position of the chisel head 42. Using the lever principle, the user operates the chisel head assembly 4 on the handle 1 with the boss 412 as the fulcrum to apply a sufficiently large torque to the ice layer, thereby improving the efficiency of ice removal. The handle 1 has multiple symmetrically distributed footplates 111 corresponding to the position of the chisel head assembly 4. When dealing with thicker ice layers, it is difficult to break the ice layer with the strength of the user's arm alone. The user can apply external force to the footplates 111 with their legs or other external tools to increase the impact force of the chisel head assembly 4 on the ice layer, further optimizing the ice-breaking effect of the chisel head assembly 4, which is suitable for dealing with some high-intensity operation needs in complex ice and snow environments.

[0029] The chisel head 42 includes a cutting edge 421 and a chisel body 422, which is fixedly connected to the connector 41. The cutting edge 421 has multiple evenly spaced raised ridges 4211 distributed along its length. These ridges increase the sharpness and grip of the cutting edge 421, making it easier to chisel into the ice, reducing the required force, preventing slippage when the chisel head 42 contacts the ice surface, and enhancing its ice-breaking efficiency and cutting ability. The evenly distributed ridges 4211 prevent stress concentration, reducing the possibility of deformation or breakage of the cutting edge 421 and extending the service life of the chisel head 42. The chisel body 422 has multiple through holes 4221 distributed radially from the chisel body 422 to the cutting edge 421. These through holes may help disperse the impact force experienced by the chisel head 42 during ice breaking, preventing stress concentration at any point, thereby improving the overall structural strength and durability. While maintaining the structural strength of the chisel head 42, the through hole 4221 can reduce the amount of material used, making the chisel head 42 lighter and requiring less effort from the user during long-term operation. The through hole 4221 can prevent ice slag from adhering to the chisel head 42 and prevent uneven force on the chisel head 42 during ice chiseling, which could lead to changes in the ice chiseling angle.

[0030] The handle 1 includes an upper telescopic joint 12, a connecting rod 13, and a lower telescopic joint 11. Both ends of the connecting rod 13 are provided with threaded rods 131, and both the upper telescopic joint 12 and the lower telescopic joint 11 are provided with internally threaded cylinders that mate with the threaded rods 131. By rotating the upper telescopic joint 12, the lower telescopic joint 11, and the connecting rod 13 relative to each other, the overall length of the handle 1 can be dynamically adjusted to improve the snow scraper's usability at different distances, enhance its adaptability, and reduce its size when storing. The handle 1 has platforms 114 on both sides corresponding to the scraper head 3. Each platform 114 on both sides of the handle 1 has a round hole 1141, and each side of the scraper head 3 has a frustum 322 that mates with the round hole 1141. The scraper head 3 forms a rotatable connection with the handle 1 through the engagement of the frustum 322 and the round hole 1141. To achieve a rotatable connection between the shovel head 3 and the handle 1, methods include, but are not limited to, connecting the shovel head 3 to the handle 1 via a pivot, hinge, or other technical means. The platforms 114 on both sides of the handle 1 are provided with mutually perpendicular first side edges 1145 and second side edges 1144. The circular hole 1141 has a first positioning hole 1142 and a second positioning hole 1143 circumferentially. The shovel head 3 is provided with a positioning screw 321. When the positioning screw 321 engages with the first positioning hole 1142, the shovel head 3 is in contact with the first side edge 1145. When the positioning screw 321 engages with the second positioning hole 1143, the shovel head 3 is in contact with the second side edge 1144. The first side edge 1145 and the second side edge 1144 respectively limit the shovel head 3 when it is coaxial with the handle 1 or perpendicular to the handle 1, allowing the shovel head 3 to be quickly positioned to a suitable position, and finally fixed to the handle 1 by the positioning screw 321. A damping shaft is located at the end of the handle 1 furthest from the shovel head 3. The brush 2 is rotatably connected to the handle 1 via the damping shaft. A knob 121 on the damping shaft controls the rotation angle of the brush 2. To change the rotation angle of the brush 2 relative to the handle 1, loosen the knob 121 and rotate the brush 2. To fix the angle between the brush 2 and the handle 1, tighten the knob 121 to maintain a fixed angle. By adjusting the knob 121, the rotation angle of the brush 2 relative to the handle 1 can be freely changed, diversifying the application scenarios of the brush 2. A hook 122 is located at the end of the handle 1 for easy storage of the snow scraper.

[0031] The shovel head 3 includes a bucket 31 and a swing arm 32. The bucket 31 has symmetrically distributed swing arms 32. The bucket 31 is used to remove snow or ice chips. The bucket 31 has multiple evenly distributed openings 311, which facilitate airflow into the bucket 31, preventing snow or ice chips from adhering to the inside of the bucket 31 and facilitating the removal of snow and ice. One end of the swing arm 32 is fixedly connected to the bucket 31, and the other end is rotatably connected to the handle 1. The end of the swing arm 32 away from the bucket 31 has a frustum 322 that mates with the round hole 1141 on the platform 114. The bucket 31 is rotatably connected to the handle 1 as the swing arm 32 rotates.

[0032] The working principle of this utility model is as follows: Rotate the swing arm 32 to make the shovel head 3 perpendicular to the handle 1, and use the positioning screw 321 to keep the shovel head 3 stably perpendicular to the handle 1. At this time, the chisel head assembly 4 is exposed, and the user uses the chisel head assembly 4 to chisel the ice layer to break it; then use the shovel head 3 to scrape and clean the ice debris.

[0033] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
