Description

A high-strength wear-resistant PU scraper for snow removal

Technical field:

The utility model relates to the application field of PU materials, in particular to the technical field of snow shovels used in cities, in particular to a high-strength wear-resistant PU scraper for snow shoveling.

Background technique:

In many northern cities, when the roads are covered with ice and snow in the cold season, they will pile up on the roads and cause inconvenience to people’s travel and traffic. Snowplows are needed to remove the ice and snow to clear the way. The blades of existing snowplows are usually made of metal materials. , its cost is high and it is easy to cause damage to the road surface, and the wear resistance of the blade itself is also relatively poor, and its service life is also relatively short.

Utility model content:

The purpose of the utility model is to overcome the shortcomings of the existing products and provide a high-strength wear-resistant PU scraper for snow removal.

The technical scheme adopted by the utility model is: a high-strength wear-resistant PU scraper for snow removal, the scraper includes a scraper main body molded by PU material with a hardness of 98A or above Shore A and a metal connection formed and fixed on the upper end surface of the scraper main body Parts, wherein, the back of the scraper body is arc-shaped, and the front lower part of the scraper body directly intersects with the back to form a pointed blade; the metal connector runs through the scraper body along the length direction of the upper end surface of the scraper body, and the metal connector has a length along the length The direction and section of the main connecting groove are "U"-shaped. The upper ends of the two side walls of the main connecting groove are respectively turned outward and down to form an inverted "U"-shaped outer flange, and the inverted "U"-shaped outer flange is filled with PU material; the lower ends of the two side walls of the main connecting groove are respectively formed with an upper slope and a lower slope embedded in the main body of the scraper; both sides of the inner bottom of the main connecting groove are respectively outwardly formed to form buckling grooves; on both sides of the metal connector The two ends of the wall are respectively provided with notches transversely penetrating through the main body of the scraper.

The snow shovel blade of the utility model utilizes the PU material whose hardness is above Shore 98A and the aluminum alloy metal connecting parts to be directly injection molded, and has the characteristics of low friction coefficient, high wear resistance, high strength, corrosion resistance and fracture resistance, and also has excellent Elastic contact with the ground will not damage the road surface when scraping, long-term contact and friction with the ground, the scraper can also be durable and not easy to damage, and the high-strength wear-resistant PU scraper for snow removal is not only simple in process steps, but also stable in structure. The installation and disassembly between devices is convenient, simple and quick.

Description of drawings:

Fig. 1 is the three-dimensional structure schematic diagram of the present utility model.

Detailed ways:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Figure 1, what is described in this embodiment is a high-strength wear-resistant PU scraper for snow removal. 1 The metal connector 2 on the upper end surface, wherein the back of the scraper body 1 is arc-shaped, and the lower front part of the scraper body 1 directly intersects with the lower part of the back side to form a sharp edge; the metal connector 2 is along the length of the upper end surface of the scraper body 1 The direction runs through the scraper main body 1, and the metal connector 2 has a main connecting groove 21 along the length direction with a "U"-shaped cross section. The outer flange 22, and the inverted "U" shaped outer flange 22 is filled with PU material; the lower ends of the two side walls of the main connecting groove 21 are respectively formed with an upper slope 23 and a lower slope 24 embedded in the scraper main body 1, using The upper inclined part 23 and the lower inclined part 24 embedded in the scraper body 1 form a reverse buckling effect, which makes the combination of the two more stable and firm; the inner bottom sides of the main connecting groove 21 respectively form a buckling groove 25 outward, which is convenient for connecting with the shovel. The connection part of the blade on the snowmobile forms a fast buckle; the two ends of the two side walls of the metal connector 2 are respectively provided with a notch 26 that runs through the main body of the scraper transversely, and the notch 26 can be used to cooperate with other tools or fixtures for positioning and fastening The position of the blade on the snowplow.

The snow shovel blade of the utility model utilizes the PU material whose hardness is above Shore 98A and the aluminum alloy metal connecting parts to be directly injection molded, and has the characteristics of low friction coefficient, high wear resistance, high strength, corrosion resistance and fracture resistance, and also has excellent Elastic contact with the ground will not damage the road surface when scraping, long-term contact and friction with the ground, the scraper can also be durable and not easy to damage, and the high-strength wear-resistant PU scraper for snow removal is not only simple in process steps, but also stable in structure. The installation and disassembly between devices is convenient, simple and quick.
