Description

Technical Field

[0001] The utility model relates to the technical field of roller shafts, and more specifically, to a new type of roller which is convenient for disassembling saw blades. Background Art

[0002] The crop crushing roller is an important part of agricultural machinery and equipment for crop crushing. Its main function is to squeeze, tear and shear crops, such as corn stalks, wheat stalks, sorghum stalks, potatoes, beans, etc., through high-speed rotating and intermeshing rollers, so as to crush the crops into smaller particles or powder for subsequent processing, utilization or return to the field.

[0003] The existing crop crushing roller has certain disadvantages when in use. Since the roller and the saw blade are welded into an integrated structure, it means that once the saw blade is worn, broken or otherwise damaged, the user cannot disassemble and replace it separately. This means that when the saw blade needs to be replaced or repaired, the user must remove the entire roller from the equipment, then go through complicated steps to remove the damaged saw blade from the roller, then weld a new saw blade, and finally reinstall the entire roller back on the equipment. This process not only consumes a lot of time and labor costs, but also increases the risk of equipment downtime due to maintenance, which may affect the processing progress and yield of crops. In addition, since the roller and the saw blade cannot be disassembled, it is not convenient for users to clean and maintain the saw blade in daily use. A large amount of debris and dust will be generated during the crushing process of crops, and these impurities are easily attached to the saw blade, affecting its working effect. If it cannot be cleaned in time, the performance of the saw blade will gradually decline and its service life will be greatly shortened. Since the saw blade is welded to the roller, it is difficult for users to thoroughly clean and maintain the saw blade, which undoubtedly increases the difficulty and cost of equipment maintenance.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 5 As shown, the utility model provides a new type of roller for facilitating the removal of saw blades, including a roller shaft 1, a slide groove 2 is provided on the surface of the roller shaft 1, a saw blade 3 is movably installed inside the slide groove 2, a circular groove 4 is provided on the right side of the roller shaft 1, a rectangular groove 5 is provided inside the circular groove 4 and extends to the inside of the slide groove 2, a round rod 6 is movably installed inside the circular groove 4, a spring 1 7 is provided between the bottom of the round rod 6 and the bottom of the circular groove 4, a sleeve plate 8 is fixedly installed on the surface of the round rod 6 and the sleeve plate 8 is located inside the rectangular groove 5, a movable plate 9 is movably installed inside the sleeve plate 8, and a spring 2 10 is provided between the movable plate 9 and the inside of the sleeve plate 8;

[0019] When the saw blade 3 needs to be replaced, the staff presses the round rod 6, and the round rod 6 moves forward inside the circular groove 4. At the same time, the thrust of the round rod 6 squeezes the spring 1 7. At this time, the movable plate 9 at the front end of the spring 2 10 is close to the side of the saw blade 3. When the round rod 6 pushes forward, the movable plate 9 slides inside the rectangular groove 5, so that the saw blade 3 close to the movable plate 9 moves synchronously, so that one end of the saw blade 3 is pushed to the notch at the other end of the slide groove 2, and then the reaction force of the spring 1 7 resets the round rod 6. Finally, the staff takes out the saw blade 3 and replaces it with another saw blade 3.

[0020] Pressing the round rod 6 causes the spring 1 7 to be in a compressed state, and at the same time, the spring 2 10 slides inside the rectangular groove 5 so that the saw blade 3 that is tightly attached to the movable plate 9 moves synchronously, thereby pushing the saw blade 3 to the notch at the other end of the slide groove 2 to take it out and replace it, and then the reaction force of the spring 1 7 resets the round rod 6. Compared with the rubbing and mixing device, this device enables the saw blade 3 to be quickly and easily disassembled when it needs to be replaced or repaired, thereby quickly restoring the normal operation of the equipment and reducing the risk of production interruption. At the same time, by quickly disassembling the saw blade 3, it can be easily cleaned and maintained, ensuring that the saw blade 3 is always kept in the best condition and extending its service life. In addition, by quickly disassembling the saw blade 3 on the surface of the roller shaft 1, safety hazards can be quickly eliminated to ensure the safety of equipment and personnel.

[0021] There are ten groups of round rods 6, each group of round rods 6 has two round rods 6, and the two round rods 6 are evenly distributed on both sides of the chute 2;

[0022] There are ten groups of round rods 6, each group of round rods 6 has two round rods 6, and the two round rods 6 are evenly distributed on both sides of the slide groove 2. The use of ten groups of round rods 6 can improve the efficiency of disassembly, thereby reducing the time spent on disassembly.

[0023] The roller 1 is made of stainless steel as a whole, and the surface of the roller 1 is smooth;

[0024] The roller 1 is made entirely of stainless steel, and the surface of the roller 1 is smooth. Stainless steel has good hardness and strength, and therefore has good wear resistance and tensile resistance, so that stainless steel can maintain stable performance in equipment environments with high load-bearing requirements. At the same time, the surface of stainless steel is smooth and not easy to adhere to dust and impurities, so it is very convenient to clean and maintain.

[0025] The inner diameter of the circular groove 4 is equal to the outer diameter of the round rod 6, and the outer diameter of the saw blade 3 is equal to the inner diameter of the slide groove 2.

[0026] The inner diameter of the circular groove 4 is set to be equal to the outer diameter of the round rod 6, so that the round rod 6 fits better when moving inside the circular groove 4. The outer diameter of the saw blade 3 is set to be equal to the inner diameter of the slide groove 2, so that the friction of the saw blade 3 inside the slide groove 2 is increased, thereby making the saw blade 3 more firmly inside the slide groove 2.

[0027] The working principle and use process of this utility model:

[0028] When the saw blade 3 needs to be replaced, the staff presses the round rod 6, and the round rod 6 moves forward inside the circular groove 4. At the same time, the thrust of the round rod 6 squeezes the spring 1 7. At this time, the movable plate 9 at the front end of the spring 10 is close to the side of the saw blade 3. When the forward thrust of the round rod 6 makes the movable plate 9 slide inside the rectangular groove 5, the saw blade 3 close to the movable plate 9 moves synchronously, thereby pushing one end of the saw blade 3 to the notch at the other end of the slide groove 2. After that, the reaction force of the spring 1 7 resets the round rod 6. Finally, the staff takes out the saw blade 3 and replaces it with another saw blade 3.
