Description

Technical Field

[0001] The present application relates to the technical field of scrap steel recycling, and in particular to a feeding structure of a scrap steel crusher. Background Art

[0002] The effective recycling of scrap metal resources can greatly reduce the exploitation and consumption of natural mineral resources, thus achieving the goals of reducing land occupation, reducing social total energy consumption, saving investment, protecting the ecological environment, and improving labor production efficiency. Especially today when natural mineral resources are extremely consumed and increasingly scarce, the position of scrap metal resources in the world economy and sustainable development strategy is becoming more and more prominent.

[0003] Among them, the scrap steel crusher is a crushing machine used to produce scrap steel crushing materials, mainly used for scrapped cars, scrapped home appliances and thin scrap steel. The scrap steel crusher plays an important role in the recycling of scrap steel, and can effectively crush the scrap steel, so as to facilitate subsequent smelting and reuse.

[0004] The existing scrap steel crusher is fed by a conveyor belt. A chute is set between the conveyor belt and the crusher feed port. The scrap steel is grabbed from the ground onto the conveyor belt, transported upward to the chute, and then slides down to the scrap steel crusher feed port. The scrap steel in the chute slides down into the scrap steel crusher by its own gravity. Since the angle of the chute is fixed, for heavy scrap steel, the scrap steel will cause a certain impact on the internal structure of the scrap steel crusher when it falls, while for light scrap steel, it may stay in the chute and cannot fall due to insufficient gravity. Utility Model Content

[0005] In order to make heavy and light scrap steel fall evenly, the present application provides a scrap steel crusher feeding structure.

[0006] The feeding structure of a scrap steel crusher provided in this application adopts the following technical solution:

[0007] A feeding structure for a scrap steel crusher, comprising:

[0008] The chute is fixedly arranged at the feed port of the scrap steel crusher;

[0009] A first bracket is rotatably mounted on the chute;

[0010] The unloading roller is rotatably arranged on the first bracket. When unloading the light weight scrap steel, the unloading roller pushes the scrap steel to slide down;

[0011] A second bracket is lifted and arranged on the chute;

[0012] The buffer plate is rotatably arranged on the second bracket, and when the heavy scrap steel is unloaded, the buffer plate blocks the sliding path of the scrap steel;

[0013] A buffer spring, with two ends respectively fixed to the second bracket and the buffer plate;

[0014] The damping rod has two ends respectively hinged to the second bracket and the buffer plate.

[0015] By adopting the above technical solution, when processing scrap steel of different weights, by adjusting the state of the feeding roller and the buffer plate, effective feeding of scrap steel of different weights is achieved. For light scrap steel, the first bracket rotates to make the feeding roller descend, and the feeding roller pushes the scrap steel down; while for heavy scrap steel, the buffer plate descends, so that the scrap steel contacts the buffer plate when it falls, driving the buffer plate to rotate, and under the action of the buffer spring and the damping rod, the buffer plate will buffer the scrap steel, thereby protecting the internal structure of the scrap steel crusher.

[0016] Optionally, the circumferential surface of the unloading roller is evenly distributed with pushing claws.

[0017] By adopting the above technical solution, the pushing claws evenly distributed on the circumferential surface of the unloading roller can push small-weight scrap steel into the scrap steel crusher, thereby improving the unloading efficiency and preventing small-weight scrap steel from staying on the chute.

[0018] Optionally, a first hydraulic cylinder is hinged on the first bracket, and one end of the first hydraulic cylinder away from the first bracket is hinged on the scrap steel crusher.

[0019] By adopting the above technical solution, by adjusting the telescopic length of the first hydraulic cylinder, the first bracket can be driven to rotate, thereby changing the position and angle of the unloading roller to adapt to scrap steel of different shapes and feeding requirements, so that the unloading roller pushes light scrap steel into the scrap steel crusher.

[0020] Optionally, a motor is fixedly mounted on the first bracket, and an output shaft of the motor is fixed to the unloading roller.

[0021] By adopting the above technical solution, the motor can drive the unloading roller to rotate, thereby pushing the small-weight scrap steel and allowing the small-weight scrap steel to enter the scrap steel crusher.

[0022] Optionally, telescopic rods are fixedly provided on both sides of the second bracket, and one end of the telescopic rod away from the second bracket is fixed on the scrap steel crusher.

[0023] By adopting the above technical solution, the telescopic rod plays a supporting and guiding role, so that the second bracket is more stable when it is lifted and moved, and the buffer plate is more stable when impacted by scrap steel.

[0024] Optionally, second hydraulic cylinders are fixedly arranged on both sides of the second bracket, and one end of the second hydraulic cylinder away from the second bracket is fixed on the scrap steel crusher.

[0025] By adopting the above technical solution, by adjusting the telescopic length of the first hydraulic cylinder, the second bracket can be driven to rise and fall, so that the buffer plate extends into the chute and contacts the heavy scrap steel, which plays a buffering role in the fall of the heavy scrap steel.

[0026] Optionally, an inner lining plate is provided on the chute, and the chute and the inner lining plate are fixed by bolts.

[0027] By adopting the above technical solution, the inner lining plate can protect the chute, so that the scrap steel directly contacts the inner lining plate. After the inner lining plate is worn, the inner lining plate can be directly replaced, thereby protecting the chute.

[0028] Optionally, a positioning protrusion is fixedly provided on the chute, and a positioning groove matching the positioning protrusion is formed on the inner lining plate.

[0029] By adopting the above technical solution, through the cooperation of the positioning protrusion and the positioning groove, the inner lining plate is made more firmly on the chute, avoiding the inner lining plate from slipping, and also playing a role in positioning the inner lining plate.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. When processing scrap steel of different weights, by adjusting the state of the feeding roller and the buffer plate, effective feeding of scrap steel of different weights is achieved. For light scrap steel, the first bracket rotates to make the feeding roller descend, and the feeding roller pushes the scrap steel down; while for heavy scrap steel, the buffer plate descends, so that the scrap steel contacts the buffer plate when it falls, driving the buffer plate to rotate. Under the action of the buffer spring and the damping rod, the buffer plate will buffer the scrap steel, thereby protecting the internal structure of the scrap steel crusher.

[0032] 2. The inner lining plate can protect the chute, allowing the scrap steel to directly contact the inner lining plate. After the inner lining plate is worn, the inner lining plate can be directly replaced, thereby protecting the chute. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0038] The present application embodiment discloses a feeding structure for a scrap steel crusher. Figure 1 and Figure 2 A feeding structure of a scrap steel crusher includes a chute 1, a first bracket 21, a feeding roller 31, a second bracket 22, a buffer plate 41, a buffer spring 42 and a damping rod 43.

[0039] For details, please refer to Figure 1 The chute 1 is fixedly arranged at the feed port of the scrap steel crusher to guide the scrap steel into the crusher. The first bracket 21 is rotatably arranged on the chute 1, and the unloading roller 31 is rotatably arranged on the first bracket 21, so that the unloading roller 31 can adjust the position as needed. When unloading small-weight scrap steel, the first bracket 21 is rotated so that the unloading roller 31 enters the chute 1, so that the unloading roller 31 can contact the scrap steel, thereby pushing the scrap steel into the scrap steel crusher.

[0040] For further information, please refer to Figure 1 The circumferential surface of the unloading roller 31 is evenly distributed with pushing claws 311. When unloading small-weight scrap steel, the pushing claws 311 can effectively push the scrap steel to slide down along the chute 1.

[0041] Please refer to Figure 1 , a first hydraulic cylinder 32 is hinged on the first bracket 21, and one end of the first hydraulic cylinder 32 away from the first bracket 21 is hinged on the scrap steel crusher. By adjusting the extension and contraction of the first hydraulic cylinder 32, the position of the unloading roller 31 can be changed, further improving the flexibility and adaptability of the unloading roller 31, so that the unloading roller 31 can be lowered when it is needed, and raised when it is not needed. In addition, a motor 33 is fixedly arranged on the first bracket 21, and the output shaft of the motor 33 is fixed to the unloading roller 31. The motor 33 can drive the unloading roller 31 to rotate, thereby applying a driving force to the scrap steel.

[0042] Please refer to Figure 1The second bracket 22 is lifted and lowered on the chute 1, and a telescopic rod 44 and a second hydraulic cylinder 45 are fixedly arranged on both sides of the second bracket 22. The ends of the telescopic rod 44 and the second hydraulic cylinder 45 away from the second bracket 22 are fixed on the scrap steel crusher. By adjusting the extension and retraction of the second hydraulic cylinder 45, the position of the buffer plate 41 can be adjusted. Among them, the telescopic rod 44 plays a guiding role in the movement of the second bracket 22, and also plays a role in reinforcing and supporting the second bracket 22.

[0043] Please refer to Figure 2 The buffer plate 41 is rotatably arranged on the second bracket 22. When unloading heavy scrap steel, the buffer plate 41 will block the sliding path of the scrap steel. The two ends of the buffer spring 42 are respectively fixed to the second bracket 22 and the buffer plate 41. The two ends of the damping rod 43 are respectively hinged to the second bracket 22 and the buffer plate 41, which can absorb the impact energy of the scrap steel, further enhancing the buffering effect of heavy scrap steel. Through the action of the buffer spring 42 and the damping rod 43, the heavy scrap steel is buffered to prevent it from directly impacting the internal structure of the scrap steel crusher, thereby protecting the scrap steel crusher.

[0044] In addition, please refer to Figure 1 and Figure 3 The chute 1 is also provided with an inner lining plate 5 to protect the chute 1 from wear. The chute 1 and the inner lining plate 5 are fixed by bolts, which facilitates the removal and installation of the inner lining plate 5. At the same time, a positioning protrusion 11 is fixedly provided on the chute 1, and a positioning groove 51 matching the positioning protrusion 11 is provided on the inner lining plate 5, thereby ensuring the accuracy of the installation of the inner lining plate 5. The mutual connection between the positioning protrusion 11 and the positioning groove 51 also reinforces the inner lining plate 5, preventing the inner lining plate 5 from slipping in the chute 1.

[0045] The implementation principle of the embodiment of the present application is as follows: for small-weight scrap steel, the position of the first bracket 21 is adjusted by the first hydraulic cylinder 32 so that the unloading roller 31 enters the chute 1. The motor 33 is started to drive the unloading roller 31 to rotate. The pushing claw 311 on the unloading roller 31 will push the small-weight scrap steel to slide down the chute 1 to the feed port of the scrap steel crusher.

[0046] For heavy scrap, the buffer plate 41 is blocked on the sliding path of the scrap by adjusting the extension of the telescopic rod 44 and the second hydraulic cylinder 45. When the heavy scrap slides down to the buffer plate 41, the buffer spring 42 and the damping rod 43 will play a buffering role to absorb the energy of the impact of the scrap.

[0047] Regularly check the wear of the inner lining plate 5, and if necessary, promptly replace the new inner lining plate 5. When replacing the inner lining plate 5, ensure that the positioning protrusion 11 matches the positioning groove 51 to ensure the accuracy of installation.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
