Description

Technical Field

[0001] This utility model relates to the field of mechanization technology, specifically to an adjustable angle crusher blade holder. Background Technology

[0002] As one of the core components of crushing equipment, the technological development of crusher blade holders directly affects crushing efficiency, equipment stability, and maintenance costs. With changes in industrial demands and advancements in materials science, blade holder technology has evolved from simple fixing to intelligent optimization.

[0003] In existing technologies, traditional shredder blade holders often cannot achieve the optimal cutting angle when the blades are installed and in operation. This is because the objects being cut have varying postures and are limited by their dimensions. Consequently, the blades are prone to uneven wear during cutting, shortening their lifespan. Furthermore, the poor cutting angle significantly reduces the cutting effect, failing to achieve the desired shredding result and impacting work efficiency and product quality. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable-angle crusher blade holder, which solves the problem that the blades cannot cut at the optimal angle due to the varying postures of the objects being cut, thus reducing the blade life.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable angle crusher blade holder, including an angle control mechanism and a rotating rod, wherein the rotating rod is equipped with eight sets of blade mounting brackets, each set of blade mounting brackets having three blades forming a Y-shaped structure, each blade mounting bracket being equipped with a compression spring, the angle control mechanism being bolted to the left side of the rotating rod, the blade mounting brackets being in groups of three, the three blade mounting brackets being mounted on the rotating rod at 120-degree intervals on the same plane, and the springs being welded between the angle control mechanism and the blade mounting brackets;

[0008] The angle control mechanism is installed on the left side of the rotating rod by an offset fixing rod threaded on it. The offset fixing rod is a threaded rod with a nut push rod installed on it. A push plate is installed on the right side of the nut push rod. The push plate is fixed to the nut push rod by a push plate fixing ring, which is an interference fit with the nut push rod. Three push rods are installed on the push plate. Each push rod is axially fixed to the push plate by a slider and a sliding pad. The slider and sliding pad do not clamp the push plate, leaving a certain axial clearance for the push rod, allowing it to move radially. The relative position of the nut push rod is determined by a fixed nut. Each push rod has eight push rings with an interference fit.

[0009] The blade mounting brackets are arranged in groups of three, and the three blade mounting brackets are connected together by a Y-shaped connector. The Y-shaped connector is rotatably connected to the blade rotation shaft, and the blade rotation shaft is connected to the blade holder. The blade holder is fixed to the blade rotation shaft with bolts and nuts. The blade rotation shaft is connected to a fixing block to form a hole with a diameter larger than that of the push rod. The fixing block is fixed to the blade rotation shaft with two screws.

[0010] Preferably, the push plate has a waist-shaped hole at a 45-degree angle to the radial direction, which allows the three push rods to retract inward.

[0011] Preferably, the tool holder has two mounting holes for mounting blades, each with a diameter of 10mm to 20mm.

[0012] Preferably, the push rod has eight interference-fitted push rings, each push ring being spaced 200mm to 300mm apart.

[0013] (III) Beneficial Effects

[0014] This utility model provides an adjustable-angle crusher blade holder. It offers the following advantages: When using the crusher blade holder with blades installed, if the object being cut has a complex shape, the blade holder can be rotated to the optimal cutting angle by rotating the nut push rod to achieve a better crushing effect and extend the blade's service life.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an adjustable angle crusher blade holder, including an angle control mechanism 1 and a rotating rod 2. The rotating rod 2 is equipped with eight sets of blade mounting brackets 3, each set of blade mounting brackets 3 having three blades forming a Y-shaped structure. Each blade mounting bracket 3 is equipped with a compression spring. The feature is that: the angle control mechanism 1 is bolted to the left side of the rotating rod 2; the blade mounting brackets 3 are in groups of three, and the three blade mounting brackets 3 are installed on the same plane at 120-degree intervals on the rotating rod 2; the spring 4 is welded between the angle control mechanism 1 and the blade mounting brackets 3.

[0023] The angle control mechanism 1 is threadedly mounted on the left side of the rotating rod 2 by an offset fixing rod 11. The offset fixing rod 11 is a threaded rod, and a nut push rod 12 is mounted on the offset fixing rod 11. A push plate 16 is mounted on the right side of the nut push rod 12. The push plate 16 is fixed to the nut push rod by a push plate fixing ring 19, which is interference-fitted to the nut push rod 12. Three push rods 13 are mounted on the push plate 16. Each push rod 13 is axially fixed to the push plate 16 by a slider 14 and a sliding pad 15. The slider 14 and the sliding pad 15 do not clamp the push plate 16, leaving a certain axial clearance for the push rod 13, allowing the push rod 13 to move radially. The relative position of the nut push rod 12 is determined by a fixing nut 18. Eight push rings 17 are interference-fitted on each push rod 13.

[0024] The blade mounting brackets 3 are arranged in groups of three, and the three blade mounting brackets 3 are connected together by Y-shaped connectors 37. The Y-shaped connectors 37 are rotatably connected to the blade rotating shaft 32, and the blade rotating shaft 32 is connected to the blade holder 31. The blade holder 31 is fixed to the blade rotating shaft 32 with bolts 33 and nuts 34. The blade rotating shaft 32 is connected to the fixing block 35 to form a hole with a diameter larger than that of the push rod. The fixing block 35 is fixed to the blade rotating shaft 32 with two screws 36.

[0025] In use, rotating the nut push rod 12 drives the push plate 16 to move to the right. Since the three push rods 13 are axially fixed on the push plate 16, the push rods 13 also move to the right. The push ring 17 on the push rod 13 and the spring 4 push the blade mounting bracket 3 to rotate. The hole of the blade mounting bracket 3 is larger than the diameter of the push rod 13. Therefore, during cutting, the blade can slightly change the cutting angle according to the shape of the object being cut. When the required cutting angle is determined, the fixing nut 18 can be rotated to the left to fix the nut push rod.

[0026] In summary, this adjustable-angle pulverizer blade holder, by rotating the nut push rod 12, causes the push plate 16 to move the push rod 13 to the left and right, thereby changing the blade angle and rotating the blade holder to the optimal cutting angle, achieving a good pulverizing effect while also extending the service life of the blades.
