Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings, wherein the same reference numerals in the drawings denote the same components or similar components.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited by the specific embodiments disclosed below.

A low friction coefficient scraper comprises a scraper body 1 and an elastic matrix 2. The scraper body 1 is provided with a bearing part 11, and the top surface and/or the bottom surface of the bearing part 11 is/are provided with a mounting groove 111; the elastic base body 2 is embedded in the mounting groove 111 and includes a wear-resistant layer 21, and the wear-resistant layer 21 is used for abutting against the outside to support the scraper body 1. In the working process of the scraper, the wear-resistant layer 21 rubs with an external structure, so that the friction resistance of the scraper body 1 is reduced to reduce the wear of the scraper body 1, and the scraper is simple in structure; the elastic base body 2 is directly clamped and installed in the installation groove 111, other positioning, anti-falling and other structures are not needed, the assembly and disassembly are convenient, and the weight of the scraper is reduced; the elastic matrix 2 has elasticity, can provide the effect that the buffering was supported for scraper blade body 1 when the scraper blade received the impact, prevents that scraper blade body 1 from splitting easily and failing when receiving the impact.

As a further optimization of the elastomeric matrix 2, the elastomeric matrix 2 is a polyurethane elastomeric matrix 2. The polyurethane elastic matrix 2 has excellent hardness characteristics and good elasticity, can provide effective elastic support when the scraper body 1 is impacted, buffers the impact force received by the scraper body 1, and protects the scraper body 1 from fracture failure due to impact.

As shown in fig. 1, the elastic base body 2 further includes a mounting layer 22, the wear-resistant layer 21 has a smaller coefficient of friction than the mounting layer 22, and the mounting layer 22 has a hardness smaller than that of the mounting layer 22. When scraper blade body 1 receives external impact, wearing layer 21 can not receive the influence or the influence that receives is very little because of coefficient of friction is little, hardness height, continues to guarantee the operating condition of scraper blade with external structure friction, and plays effectual supporting role, does not warp easily, and installation layer 22 is little because of hardness, has good elastic deformation ability, can provide good effectual buffering for scraper blade body 1. From this, through setting up coefficient of friction difference, the hardness difference between wearing layer 21 and the installation layer 22 for wearing layer 21 mainly plays wear-resisting and the little function of coefficient of friction, reduces the frictional resistance that scraper blade body 1 received, and installation layer 22 mainly plays and closely the joint with mounting groove 111, and provides good elastic support for scraper blade body 1, makes it not receive the harm of impact force.

Specifically, the wear-resistant layer 21 is parallel to the surface of the bearing part 11, and extends beyond the bearing part 11 in the direction away from the mounting groove 111. In a normal working state, the wear-resistant layer 21 mainly rubs with an external structure, so that the contact area of the scraper and the external structure is reduced, and the friction damage to the scraper body 1 is reduced; in addition, even under heavy load, behind the mounting layer 22 by compression deformation, this structural setting can guarantee that wearing layer 21 still can rub with external structure, can not lead to only scraper blade body 1 and external friction to guaranteed that the scraper blade can normally work under the special circumstances, production can not be interrupted.

As shown in fig. 1-2, the bearing part 11 is further provided with an installation cavity 112, a wall of the installation cavity 111 is provided with an opening 113 communicated with the installation cavity 112, and a part of the installation cavity 112 far away from the opening 113 is communicated with the outside. From this structure, elastic matrix 2 can be convenient from installation cavity 112 by the dismouting, its installation and change of being convenient for, and the deformation of elastic matrix can be held in opening 113's setting for elastic matrix 2 has sufficient space to carry out elastic deformation, prevents that elastic matrix 2 from being compressed excessively and leading to failing.

As shown in fig. 1, the mounting groove 111 is disposed on the bottom surface of the load-bearing part 11, and an opening 113 is opened on the top wall and one of the side walls of the mounting groove 111. The structure is beneficial to reducing the weight of the scraper and lightening the load, and the mounting groove 111 and the opening 113 are arranged on the bottom surface of the bearing part 11, so that foreign matters can not directly fall into the mounting groove, and the mounting groove can be kept relatively clean in severe environment.

As shown in fig. 3, the cross-sectional profile of the mounting groove 111 is gradually reduced from the notch to the groove bottom. When the scraper blade received the impact, elastic matrix 2 can compress, and structural design from this, the profile of mounting groove 111 can guide elastic matrix 2 to warp, has prevented to influence work because elastic matrix warp improper supporting force that leads to the scraper blade body to receive inhomogeneous to this can play better elastic support and cushioning effect.

As for the arrangement of the mounting groove 111, as a further optimization, as shown in fig. 4, the mounting groove 111 is a through groove. The weight of scraper blade is further alleviateed to elastic matrix 2 has still kept good wear-resisting and elastic support effect, and elastic matrix 2 directly pack into can, the dismouting is more convenient, corresponds, and elastic matrix 2 makes also more convenient, can realize that the integration buffering warp, and when the scraper blade received the impact, both ends all can provide the power that warp the support from top to bottom, and the buffering support effect is better. It should be noted that the orientation description used in the above description is only for convenience of drawing review and should not be taken as a limitation on the present application, such as "upper and lower ends".

Specifically, as shown in fig. 4, the elastic base 2 is provided with wear-resistant layers 21 at two ends of the through groove, respectively. From this structure, in the use of scraper blade, elastic matrix 2's wear resistance further improves, and it can provide two ascending buffering and wear-resisting functions in direction for scraper blade body 1, has further protected scraper blade body 1, prevents that it from receiving the harm.

In some embodiments, as shown in fig. 4, the present invention further includes a positioning pin 3, the positioning pin 3 is a column whose cross-sectional profile is reduced from the center to two ends, the positioning pin 3 is inserted into the elastic base 2 and the two ends are abutted against the groove walls of the through grooves, and the two ends of the positioning pin 3 are further provided with positioning rings 31 embedded into the elastic base 2. The two ends of the positioning pin 3 are abutted against the wall of the through groove, so that the elastic base body 2 is fixed in the mounting groove 111, and when the elastic base body 2 is impacted, the elastic base body is not easy to move in the mounting groove 111 and does not easily generate longitudinal displacement or fall out of the mounting groove 111; the positioning ring 31 is embedded in the elastic base body 2, and under the action of clamping with the elastic base body 2, when the elastic base body 2 is impacted, the transverse deviation and inclination or overlarge vibration are not easy to occur. With the structure, the positioning pin 3 is arranged to stabilize the elastic base body 2 in the mounting groove 111, and the positioning ring 31 is arranged to prevent the elastic base body 2 from transversely deviating in the mounting groove 111, so that the reliable working performance of the elastic base body 2 is ensured.
