Description

1 TARIFF A NEW BLADE MOUNTING MECHANISM FOR ROTOR-TYPE CRUSHER MACHINES. Technical Area The invention addresses the time loss and assembly difficulties experienced during blade changes in rotor-type crushing machines. with a blade assembly mechanism developed to eliminate the risk of errors and reduce maintenance costs. It is related. The invention specifically involves detachable multi-edged cutters mounted on carrier blade housings fixed onto a rotor. By mounting the cutting tips, only the cutting tips are attached without interfering with the rotor or shafts. Blade assembly that provides ease of use and longer blade life thanks to its replaceable blades. It is related to the mechanism. State of the Art Rotor type crushers are widely used in the livestock, agriculture and biomass processing sectors. These are shredding machines with a high-speed rotor structure. These machines are used for shredding straw, hay, shredding fibrous materials such as corn stalks, pulp, and similar materials to obtain outputs of specific sizes. It provides this service. Blades mounted on the rotor cut or tear the material into smaller pieces. In current systems, blades are typically mounted via shafts located around the rotor. The blades, designed with holes, are fixed onto these shafts. The direction of the blades... and the use of different cutting edges by rotating their faces has been developed to extend their lifespan. It is a solution. However, this method has serious disadvantages. During blade replacement... The shafts on the rotor must be completely removed, and during this process the bushings and blades must be disassembled. 25 This makes the assembly process laborious and time-consuming. This situation increases the maintenance time. This prolongs the process, leading to the machine being out of service for extended periods and reducing production efficiency. This reduces the risk of operator error during assembly, and faulty assembly can damage the rotor. This negatively affects the balance and performance of the machine. This non-ergonomic process is the same. It also poses serious risks in terms of occupational safety. 30 Extending blade life and simplifying the connection method in rotor crusher machines. Many studies have been conducted and new systems developed for this purpose. One of these studies is, This invention is the subject of patent application number WO2017007449A1. The invention is mounted on a rotor. This relates to the multi-edged, replaceable blade tips. The insert type 35 is placed in the blade bodies. 2 As the cutting edges wear down, they can be rotated and a new edge can be used, thus extending the blade's life. However, this During blade tip replacement in the system, the connection points on the rotor must be checked again. Intervention is required. This includes removing the blade carrier housing or securing the inserts. The maintenance process is complex because the screws need to be unscrewed. Therefore, the shafts need to be removed. Although the necessity has decreased, the assembly-disassembly process still takes a long time, and the machine is out of service for 5 months. No effective solution can be offered to shorten the time. Furthermore, incorrect tightening during assembly or Alignment errors can negatively affect rotor balance, which eliminates the risk of operator error. It does not remove it. Another study is the invention that is the subject of patent application CA2402097A1. The invention involves straw 10 This relates to securing the blades to the chopper rotors with pin connections. This solution uses screws or Although it speeds up blade changes considerably compared to using bolts, the shafts or pins on the rotor It needs to be disassembled again. There is a risk of the bushings and blades separating during the removal of the pins. This can be a problem, which still makes assembly a laborious process. Therefore, maintenance Although the downtime is somewhat reduced, it is not possible to prevent the machine from being out of service for extended periods. Also, 15 If the operator does not insert the pin correctly or ensure sufficient tightness, the rotor will malfunction. It can operate erratically. Therefore, there is a risk of faulty assembly as well as issues with ergonomics and occupational safety. The problems cannot be completely resolved. Another study is the invention that is the subject of patent application number US6692351B2. The invention concerns harvesting 20 The issue is related to the fact that the rotor and fixed blade arrangement in the chopper are reconfigurable. This This allows the material flow and shredding size to be adjusted. However, this design of the blades... It does not offer a radical change in the mounting method; the mounting of the blades onto the rotor is still the same. This is done with mechanical fastening elements and the connection on the rotor during the change. Intervention at these points becomes necessary. As a result, the maintenance period is extended, 25 The machine downtime increases, and the risk of the operator making incorrect assembly is not eliminated. In addition to its reconfigurable design offering flexibility in use, it also prioritizes ergonomics and occupational safety. It does not offer a facilitating solution in this regard. Current studies highlight the need to disassemble the shafts during blade replacement, the length of maintenance time, and the operator's 30 It does not fundamentally eliminate the risk of errors and occupational safety problems. As a result... a blade mounting mechanism that eliminates the disadvantages existing in the current technology The existence of a need and the inadequacy of existing solutions necessitate an improvement in the relevant technical field. It has made it mandatory. 35 3 Brief Description of the Invention The present invention meets the aforementioned requirements while eliminating all disadvantages. and some additional advantages are experienced during blade replacement in rotor-type crusher machines. 5 designed to eliminate wasted time, assembly difficulties, risk of errors, and maintenance costs.

The goal is to ensure that maintenance can be carried out. Another objective of the invention is to design cutting edges with different orientations and 20 The ability to use it facing upwards increases the lifespan of the blade and allows for a longer use of the same blade. The goal is to ensure efficiency. Another purpose of the invention is to allow for the use of different materials thanks to the modular structure of the cutting edges. The aim is to enable the use of alternative blade designs according to their characteristics. 25 Another purpose of the invention is to enable the fixation of cutting edges through a single connection point. eliminating the risk of errors during assembly and ensuring the rotor is balanced The goal is to ensure its functioning. Another purpose of the invention is to facilitate maintenance thanks to the fact that the cutting edges can be easily removed and replaced. shortening service times and reducing machine downtime is to ensure.
