Description

Technical Field

[0001] The utility model belongs to the technical field of composite lining plates, and in particular relates to a high-strength composite lining plate. Background Art

[0002] Jaw crusher is a commonly used crushing equipment. Its core structure consists of two jaw plates, the movable jaw and the static jaw, forming a crushing chamber, simulating the movement of the two jaws of an animal to complete the material crushing operation. Its working principle is mainly to crush the material through the periodic movement of the movable jaw. In the process of the movable jaw swinging around the suspension mandrel to the fixed jaw, the material is subjected to the combined effects of crushing, splitting and bending, thereby achieving crushing. Since the liner on the jaw plate is in direct contact with the material to be crushed, it will produce greater wear and tear, and needs to be replaced regularly. For the traditional integral composite liner, since the wear rate of the bottom is generally much higher than that of the top, the composite liner is generally removed after the bottom is severely worn and reinstalled on the jaw plate after being turned upside down. Although this solves the problem of the upper part of the composite liner not being utilized to a certain extent, due to the uneven distribution of the degree of wear during use, in the subsequent replacement of the composite liner, there are still some areas of the replaced composite liner, especially some areas in the middle section that have not reached the level of abandonment, thus causing a certain amount of waste. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a high-strength composite lining. By setting a combined lining composed of multiple groups of composite linings, the position of each group of composite linings can be switched according to the actual wear of each composite lining during operation. For example, the composite lining located at the lower part with more serious wear can be swapped with the composite lining located at the upper part. When the upper composite lining and the lower composite lining are both seriously worn, the composite linings of these two parts can be replaced separately without replacing the composite lining in the middle section with less serious wear, thereby extending the service life of the composite lining in the middle section. Any composite lining can be replaced separately according to the wear condition, so that each composite lining can be fully utilized and the waste of plate materials can be reduced.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: a high-strength composite lining, comprising a base plate, a mounting groove is provided on the front side of the base plate, a trapezoidal groove is further provided on the inner side of the mounting groove, a combined lining is provided inside the mounting groove, the combined lining comprises a plurality of groups of composite linings, the front sides of the composite linings are provided with crushing teeth, the back sides of the composite linings are provided with trapezoidal insertion sections, the trapezoidal insertion sections are inserted and connected with the trapezoidal grooves, a first screw hole is provided on the base plate located in the mounting groove, a countersunk screw hole is provided on the composite lining, a hexagon socket bolt is connected between the countersunk screw hole and the first screw hole, and a rubber buffer pad is provided on the back side of the composite lining between the upper and lower groups of trapezoidal insertion sections.

[0005] The beneficial effects of the utility model are as follows: the device, by arranging a combined lining composed of multiple groups of composite linings, can switch the position of each group of composite linings according to the actual wear conditions of each composite lining during operation. For example, the composite lining located at the lower part with more serious wear can be swapped with the composite lining located at the upper part. When both the upper and lower composite linings are seriously worn, the composite linings of these two parts can be replaced separately without replacing the composite lining in the middle section with less serious wear, thereby extending the service life of the composite lining in the middle section. Any composite lining can be replaced separately according to the wear conditions, so that each composite lining can be fully utilized and the waste of plate materials can be reduced.

[0006] In order to strengthen the structural strength of the base plate and combined lining plate:

[0007] As a further improvement of the above technical solution: a triangular area is formed between two trapezoidal grooves close to each other between two adjacent groups of composite lining plates.

[0008] The beneficial effect of this improvement is that the setting of the triangular area, utilizing its triangular shape, has a certain bearing capacity for the oblique impact force transmitted from the composite lining to the base plate, and also plays a supporting role for the composite lining, thereby enhancing the structural strength of the base plate and the combined lining.

[0009] In order to facilitate the use of hexagon socket bolts to fix the composite liner:

[0010] As a further improvement of the above technical solution: the two trapezoidal grooves corresponding to the same composite lining plate are both in the shape of right-angled trapezoids, wherein the right-angle position is located on the side where the two trapezoidal grooves are close to each other.

[0011] The beneficial effect of this improvement is that the two trapezoidal grooves corresponding to the same composite lining plate are both in the shape of a right-angled trapezoid, wherein the right-angle position is located on the side where the two trapezoidal grooves are close to each other, so that the trapezoidal insertion section of the composite lining plate can be directly supported after being inserted into the trapezoidal groove, making it convenient to fix the composite lining plate using hexagon socket bolts later.

[0012] In order to connect and fix the device to the jaw plate:

[0013] As a further improvement of the above technical solution: a second screw hole is provided on the back side of the substrate.

[0014] The beneficial effect of this improvement is that the second screw hole is used to cooperate with the bolt to connect and fix the device to the jaw plate.

[0015] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0024] like Figure 1-6 As shown, a high-strength composite lining comprises a base plate 1, the front side of the base plate 1 is provided with an embedding groove 2, the inner side of the embedding groove 2 is also provided with a trapezoidal groove 3, the interior of the embedding groove 2 is provided with a combined lining plate 5, the combined lining plate 5 comprises a plurality of groups of composite lining plates 6, the front sides of the composite lining plates 6 are provided with crushing teeth 7, the back sides of the composite lining plates 6 are provided with a trapezoidal insertion section 8, the trapezoidal insertion section 8 is inserted and connected with the trapezoidal groove 3, the base plate 1 is provided with a first screw hole 9 in the embedding groove 2, the composite lining plate 6 is provided with a countersunk screw hole 10, a hexagon socket bolt 11 is connected between the countersunk screw hole 10 and the first screw hole 9, and the back side of the composite lining plate 6 is provided with a rubber buffer pad 12 between the upper and lower groups of trapezoidal insertion sections 8.

[0025] The device is provided with a combined lining plate 5 composed of multiple groups of composite lining plates 6. The position of each group of composite lining plates 6 can be switched according to the actual wear conditions of each composite lining plate 6 during operation. For example, the composite lining plate 6 with more serious wear located at the lower part can be swapped with the composite lining plate 6 located at the upper part. When both the upper composite lining plate 6 and the lower composite lining plate 6 are seriously worn, the composite lining plates 6 of these two parts can be replaced separately without replacing the composite lining plate 6 in the middle section which is not seriously worn. This can extend the service life of the composite lining plate 6 in the middle section. Any composite lining plate 6 can be replaced separately according to the wear conditions, so that each composite lining plate 6 can be fully utilized and the waste of plate materials can be reduced.

[0026] A triangular area 4 is formed between two trapezoidal grooves 3 near each other between two adjacent groups of composite lining plates 6 .

[0027] The setting of the triangular area 4, by utilizing its triangular shape, has a certain bearing capacity for the oblique impact force transmitted from the composite lining to the base plate 1, and also plays a supporting role for the composite lining 6, thereby strengthening the structural strength of the base plate 1 and the combined lining 5.

[0028] The two trapezoidal grooves 3 corresponding to the same composite lining plate 6 are both in the shape of right-angled trapezoids, wherein the right-angle position is located on the side where the two trapezoidal grooves are close to each other.

[0029] The two trapezoidal grooves 3 corresponding to the same composite lining plate 6 are both in the shape of right-angled trapezoids, wherein the right-angle position is located on the side where the two trapezoidal grooves are close to each other, so that the trapezoidal insertion section 8 of the composite lining plate 6 can be directly supported after being inserted into the trapezoidal groove 3, which is convenient for fixing with the hexagon socket bolts 11 later.

[0030] A second screw hole 13 is provided on the back side of the substrate 1 .

[0031] The second screw hole 13 is used to cooperate with the bolt to connect and fix the device to the jaw plate.

[0032] Working principle and use process of the utility model: When the device is used, the trapezoidal insertion section 8 on the back of the composite lining plate 6 is inserted into the corresponding trapezoidal groove 3 from top to bottom in sequence, and the hexagon socket bolt 11 is used to connect the first screw hole 9 and the countersunk screw hole 10, so as to fix the composite lining plate 6 on the base plate 1. When the crushing work is carried out, the combined lining plate 5 composed of multiple groups of composite lining plates 6 crushes the materials entering the crusher through the crushing teeth 7. During the crushing process, the rubber buffer pad 12 can play a certain buffering role for the impact force received by the composite lining plate 6. The setting of the triangular area 4, using its triangular shape, has a certain bearing capacity for the oblique impact force transmitted to the base plate 1 by the composite lining plate, and also plays a supporting role for the composite lining plate 6, thereby strengthening the structural strength of the base plate 1 and the combined lining plate 5. For the traditional integral composite lining plate, since the wear rate of the bottom is generally much higher than that of the top, the composite lining plate is generally removed after the bottom is severely worn and reinstalled on the jaw plate after being turned upside down. Although the problem of the unutilized upper part of the composite liner has been solved to a certain extent, due to the uneven distribution of wear during use, some areas of the replaced composite liner, especially some areas in the middle section, have not reached the level of waste in the subsequent replacement of the composite liner, resulting in a certain amount of waste. The present device, by providing a combined liner 5 composed of multiple groups of composite liner 6, can switch the position of each group of composite liner 6 according to the actual wear of each composite liner 6 during operation. For example, the composite liner 6 with more severe wear at the lower part can be exchanged with the composite liner 6 at the upper part. When both the upper and lower composite liner 6 are severely worn, the composite liner 6 of these two parts can be replaced separately without replacing the composite liner 6 in the middle section which is not severely worn, thereby extending the service life of the composite liner 6 in the middle section. Any composite liner 6 can be replaced separately according to the wear condition, so that each composite liner 6 can be fully utilized and the waste of plate materials can be reduced.
