Description

Technical Field

[0001] This utility model relates to the field of track cutting machine technology, and specifically to a magnet assembly structure for a track cutting machine. Background Technology

[0002] A rail cutting machine is a mechanical tool powered by a two-stroke engine. It uses a support arm to fix the machine to the rail and employs a grinding wheel as the cutting disc to cut the rail. It is mainly used for rail cutting, rebar cutting, metal material cutting, road repair, fire rescue, and other operations.

[0003] During the cutting process, iron filings are inevitably generated. The size of the iron filings produced by the cutting machine when cutting rails varies depending on factors such as the cutting method, the shape and material of the blade, and is generally between 0.5 and 5 millimeters. Due to the special nature of the rail cutting machine's operation, it is clamped onto the rail for cutting, the cutting position is fixed, and the range of iron filings ejected during cutting is fixed.

[0004] Existing domestic and international rail cutting machines do not collect and clean up metal scrap. If metal scrap is not collected and cleaned up in a timely manner, it will have adverse effects on the equipment and the environment. First, metal scrap may clog the air filter of the rail cutting machine, affecting the cutting machine's power; in more serious cases, it may even enter the engine through the air filter, causing engine damage. Second, if metal scrap adheres to the magnet of the magnetic flywheel, it can cause the magnetic flywheel to interfere with and jam the igniter, affecting the lifespan of the cutting machine. In addition, metal scrap also pollutes the environment, thereby affecting the health of employees. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a magnet assembly structure for a track cutting machine, which is simple in structure, reduces the failure rate and pollution to the surrounding environment, and extends the service life.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A magnet assembly structure for a track cutting machine includes a cutting machine bracket, an engine, and a saw blade. The saw blade is connected to the front end of the cutting machine bracket, the engine is mounted on the cutting machine bracket, and a magnet is fixed to the bottom side of the cutting machine bracket and behind the cutting blade. The engine is also provided with an air filter intake channel, and a magnet is fixed to the engine and to the side of the air filter intake channel.

[0008] A further technical solution is that the first magnet and the second magnet are rectangular, circular or other shapes, generally adopting a rectangular structure, so that more debris can be adsorbed when it is blown by.

[0009] The beneficial effects of this utility model are as follows: The magnetic assembly structure of the rail cutting machine of this utility model has a fixed range of iron chip spraying during cutting. A magnet is fixed on the cutting machine bracket at the position closest to the iron chip generation point, which adsorbs and collects 95% of the iron chips, reducing environmental pollution. The iron chips on the magnet are quickly cleaned after each cut. A magnet is fixed in the air intake channel of the air filter, which can adsorb 100% of the iron chips passing through the channel, so that the air reaching the air filter does not contain iron chips, extending the service life of the air filter assembly, and thus extending the engine life.

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0017] See Figures 1 to 4As shown, a magnet assembly structure for a track cutting machine includes a cutting machine bracket 7, an engine 6, and a saw blade 1. The saw blade 1 is connected to the front end of the cutting machine bracket 7. The engine 6 is mounted on the cutting machine bracket 7. A magnet 2 is fixed to the bottom side of the cutting machine bracket 7, behind the cutting blade 1. The engine 6 also has an air filter inlet channel 5, and a magnet 3 is fixed to the side of the engine 6, near the air filter inlet channel 5. Magnets 2 and 3 are rectangular, circular, or other shapes, but a rectangular structure is generally used to attract more debris when it is blown by.

[0018] In this embodiment, during the process of cutting the rail, the metal shavings generated are sprayed in a directional manner toward the magnet 2 due to the rotation of the cutting blade 1. They are then attracted and collected by the magnet 2. After the iron shavings accumulate on the magnet, they can be quickly cleaned and reused.

[0019] Engine 6 is also equipped with an air filter assembly 4. A second magnet 3 is installed inside the air filter intake passage 5. During injection molding, the magnet is directly injected into the plastic part as an insert, making the structure more reliable and preventing it from falling out. This allows for 100% collection of iron filings from the air intake passage, preventing them from entering the air filter assembly 4. Since the iron filings cannot reach the air filter assembly 4, they will not enter the engine 6. Iron filings on the second magnet 3 only need to be cleaned simultaneously when cleaning the air filter assembly 4, extending the service life of the air filter assembly 4 and consequently extending the service life of the engine 6. The second magnet 3 does not require frequent cleaning; it only needs to be cleaned when replacing the air filter in the air filter assembly 4, and it can be reused after cleaning.

[0020] The above embodiments are merely examples of this utility model and are not intended to limit the implementation and scope of this utility model. All technical solutions that are the same as or equivalent to the contents described in the claims of this utility model should be included within the protection scope of this utility model.
