Description

Technical Field

[0001] The utility model relates to the technical field of tire shredding, in particular to an assembled blade for a tire shredder. Background Art

[0002] With the gradual improvement of people's living standards and the rapid development of the logistics industry, the number of private cars and trucks in my country has increased year by year. The increase in the number of vehicles has driven economic development. At the same time, the consumption and wear of car tires have also generated a lot of garbage - waste tires. A few years ago, waste tires were thrown away as garbage, which greatly polluted the environment on which we depend for survival. At this time, a new industry has quietly emerged, which is waste tire recycling.

[0003] When recycling waste tires, they are usually crushed. The crushed tires are convenient for subsequent processing. When crushing tires, double-shaft crushers are generally used. Existing blades (such as Figure 5 ) When processing larger tires or processing too much tire material at one time, the force is too great and it is very easy to break. If it is too wide, the side of the cutter head will be severely worn and it will be very easy to break. If it is too narrow, the cutter head and the tool body will be misaligned when cutting the tire, and the cutter head is not easy to replace after it is damaged.

[0004] For this reason, we propose a kind of assembled blade for tire shredder. Summary of the invention

[0005] The utility model aims to provide an assembled blade for a tire shredder to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled blade for a tire shredder, comprising a mounting block;

[0007] The mounting block is provided with a tool body, the tool body is provided with a tool head, the tool head is provided with tool corner 1, tool corner 2 and tool corner 3, the mounting block is fixedly connected with a tool slot, the tool body is provided with a tool groove, and the tool body is provided with a mounting hole.

[0008] Preferably, a hexagonal hole is provided on the mounting block.

[0009] Preferably, the first angle of the tool bending angle is 86°, the second angle of the tool bending angle is 67°, and the third angle of the tool bending angle is 142°.

[0010] Preferably, a knife back is threadedly mounted on the mounting block.

[0011] Preferably, four mounting holes are provided, and the mounting holes are threaded holes. The tool body, the tool back and the mounting block are all provided with mounting holes.

[0012] Preferably, the tool slot on the tool body accounts for 51% of the bottom area of ​​the tool body.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. A hexagonal hole is opened on the mounting block. After installation by the staff, the hexagonal hole design has a greater torque and stronger force endurance than the existing octagonal hole design, thus achieving a more durable effect.

[0015] 2. The angle of the tool angle 1 is 86°, the angle of the tool angle 2 is 67°, and the angle of the tool angle 3 is 142°. The angle of the existing blade is too small, and the tire is easy to slip on the knife. If the angle is too large, it is not easy to hook the tire for crushing. When processing larger tires or processing too much tire material at one time, it is easy to break due to excessive force. Through the angle design of the tool angle 1, the tool angle 2 and the tool angle 3, such an angle is easy to hook the tire for feeding, thereby reducing the problem that the tire is easy to slip on the knife and the angle is too large, it is not easy to hook the tire for crushing, and when processing larger tires or processing too much tire material at one time, it is easy to break due to excessive force.

[0016] 3. The knife back is threadedly installed on the mounting block, and the tool body and the knife back can be installed flexibly. The staff can increase or decrease the number of tool bodies according to their own production needs. The more tool bodies there are, the smaller the output size is, and the higher the output is. And it is very flexible to replace the tool body and the knife back later. Compared with the existing integrated knife, there is no need to remove the blade as a whole, only the tool body and the knife back are needed, which greatly reduces the time for users to maintain the machine and reduces the maintenance cost.

[0017] 4. The tool slot on the tool body is designed to account for 51% of the bottom area of ​​the tool body, thereby reducing the existing slot width, which causes serious wear on the side of the cutter head and is easy to break, and the slot is too narrow, which causes the cutter head and the tool body to be misaligned when cutting tires. A slot that is too deep will affect the service life of the cutter head and the tool body, and a slot that is too shallow will cause inaccurate positioning and easy misalignment.

[0018] 5. There are four mounting holes, which are threaded holes. The tool body, tool back and mounting block are all provided with mounting holes. The screw hole pitch is 50-80-50. The main advantage of the pitch design with tight ends and wide middle is that the tool body can be fixed on the mounting block to the greatest extent, so that when the tool body is subjected to crushing force, it is not easy to be uncovered and separated from the mounting block.
