Description

Technical Field

[0001] The utility model relates to the technical field of scrap steel recycling, in particular to a high-efficiency hydraulic baler for scrap steel. Background Art

[0002] Scrap steel refers to the steel waste (such as trimmings, heads, etc.) that does not become products in the production process of steel mills, as well as the steel materials in equipment and components that are scrapped after use. Scrap steel is steel, and scrap iron is pig iron. They are collectively called scrap steel. The total amount of scrap steel produced in the world each year is 300 to 400 million tons, accounting for about 45 to 50% of the total steel production, of which 85 to 90% is used as steelmaking raw materials, and 10 to 15% is used for casting, ironmaking and recycled steel.

[0003] For example, a Chinese patent (publication number: CN217375190U) discloses a high-efficiency hydraulic baler for scrap steel processing, comprising a base, a processing box is fixedly installed on the top of the base, a fixed frame is fixedly installed on both sides of the processing box, a top plate is fixedly installed on the top of the fixed frame, an electric hydraulic cylinder is fixedly installed at the center of the bottom end of the top plate, a pressing plate is fixedly installed on the telescopic end of the electric hydraulic cylinder, a slide groove is opened at the bottom end of the base, a slider is slidably connected inside the slide groove, and a lead screw is rotatably connected on both sides of the slide groove. The utility model drives the lead screw to rotate by the rotation of a first servo motor installed, drives the slider to move by the rotation of the lead screw, drives the baffle to move by the movement of the slider, so as to facilitate the hydraulically formed scrap steel to be moved out of the processing box, and drives the gear to rotate by the rotation of a second servo motor installed, drives the push plate to move by the rotation of the gear, and moves the formed scrap steel out of the baffle through the push plate, thereby effectively improving the working efficiency of scrap steel packaging.

[0004] The above-mentioned high-efficiency hydraulic baler for scrap steel processing still has certain shortcomings. The first servo motor is used to rotate the screw rod, the screw rod is used to move the slider, and the slider is used to move the baffle, so that the formed scrap steel is moved out of the processing box. However, since the screw rod is located below the baffle, during the movement of the baffle, some iron filings of the scrap steel after hydraulic pressure will still be hung into the screw rod, affecting the rotation of the screw rod, resulting in the scrap steel being unable to be moved to the outside and transported. Therefore, the present application proposes a high-efficiency hydraulic baler for scrap steel to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a high-efficiency hydraulic baler for scrap steel, which has the advantage of convenient pushing out and solves the problem of inconvenient pushing out of the existing high-efficiency hydraulic balers for scrap steel.

[0011] Furthermore, the thread of the first screw rod is divided into two sections, and the directions of the two sections of threads are opposite. The right side of the first screw rod is rotatably connected to the right side of the inner cavity of the shell through a bearing seat.

[0012] By adopting this technical solution, the first screw rod rotates to drive the two moving blocks to move relative to each other or away from each other at the same time.

[0013] Furthermore, a sliding rod is fixed between the left and right sides of the inner cavity of the shell, and the moving block is slidably connected to the outer surface of the sliding rod.

[0019] Furthermore, the pushing mechanism includes a box body fixed on the lower surface of the top plate, a second motor fixed to the back of the inner cavity of the box body, a rotating rod fixed to the output shaft of the second motor, two first bevel gears fixed to the outer surface of the rotating rod, a second bevel gear meshed with the outer surface of the first bevel gear, a second screw rod fixed to the lower surface of the second bevel gear, a rod sleeve threadedly connected to the outer surface of the second screw rod, a fixing block fixed to the lower surfaces of the two rod sleeves, and an electric push rod fixed to the left side of the fixing block.

The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0043] The working principle of the above embodiment is:

[0044] (1) After the cylinder 8 drives the pressing plate 9 to squeeze the scrap steel, the first motor 301 is started. The first motor 301 drives the first screw rod 302 to rotate. Since the two threads of the first screw rod 302 are in opposite directions, when the first screw rod 302 rotates, it will drive the two moving blocks 303 to move relative to each other at the same time, and the moving blocks 303 will slide on the outer surface of the slide rod. The moving blocks 303 move, driving the pulley 304 to slide on the moving blocks 303. The pulley 304 will drive the cross plate 305 and the connecting rod 307 to move together, and the spring 306 will be squeezed by the cross plate 305. The ejector plate 308 is driven to move by the connecting rod 307. The ejector plate 308 pushes the scrap steel to the outside of the shell 1, which is convenient for the next operation of the scrap steel and improves the packaging efficiency.

[0045] (2) When the scrap steel moves to the top of the shell 1, the second motor 502 is started. The second motor 502 drives the rotating rod 503 and the two first bevel gears 504 to rotate together. The first bevel gear 504 drives the second bevel gear 505 and the second screw rod 506 to rotate together. The two second screw rods 506 rotate to drive the rod sleeve 507 to move. The rod sleeve 507 drives the limit block to slide on the outer surface of the limit rod to increase the stability of the rod sleeve 507 when moving. When the rod sleeve 507 moves, it drives the fixed block 508 to move together, so that the fixed block 508 moves to the right side of the scrap steel. At this time, the electric push rod 509 is started, and the electric push rod 509 pushes the scrap steel to move, so that the scrap steel moves to the left conveyor belt 4, which is convenient for the transportation of the scrap steel.
