Description

Technical Field

[0001] This utility model belongs to the field of material crushing technology and relates to a shear crushing device. Background Technology

[0002] In the processing of solid materials, crushing is a crucial step in reducing material size and is widely used in mining, metallurgy, building materials, and chemical industries. Based on different crushing principles, common crushing equipment mainly includes jaw crushers, cone crushers, impact crushers, and shear crushers. Among them, shear crushers, due to their unique crushing method, exhibit good adaptability and stability when processing materials with a certain degree of toughness and ductility.

[0003] Shear crushers primarily use two relatively moving blades or crushing teeth to apply shearing force to materials, causing them to fracture or tear under tension and shearing, thus achieving the crushing purpose. These devices typically have advantages such as compact structure, low energy consumption, and low noise, and are suitable for crushing materials such as plastics, rubber, scrap metal, and wood. Shear crushers have been widely used in resource recycling and waste treatment.

[0004] However, with the continuous expansion of industrial production scale, the requirements for crushing efficiency and capacity are increasing. In scenarios such as stone processing and construction waste treatment, it is often necessary to efficiently crush large quantities of hard materials. Existing shear crushing equipment, due to its relatively slow crushing speed and limited processing capacity per unit time, is difficult to meet the actual needs of modern large-scale rapid crushing operations. Utility Model Content

[0005] The purpose of this invention is to provide a shearing crushing device with a novel structural design that enables rapid crushing and is suitable for processing hard materials such as stone.

[0006] To solve the above-mentioned technical problems, this utility model provides a shearing crushing device, including a crushing cylinder with an open top, a vertical shearing column rotatably connected inside the crushing cylinder, the inner wall of the crushing cylinder gradually inclined downwards towards the vertical shearing column, multiple vertically arranged and circumferentially distributed fixed shearing bars connected to the inner wall of the crushing cylinder, with a material drop gap between each pair of fixed shearing bars, multiple movable shearing bars corresponding one-to-one with the fixed shearing bars connected to the outer side of the vertical shearing column, a support cylinder connected to the lower end of the crushing cylinder, an installation cylinder provided inside the support cylinder, a drive motor for driving the rotation of the vertical shearing column installed inside the installation cylinder, multiple circumferentially distributed material drop holes opened at the bottom of the crushing cylinder between the inner wall of the crushing cylinder and the outer wall of the vertical shearing column, and a discharge channel communicating with the material drop holes on the support cylinder.

[0007] By adopting the above technical solution, the material is added into the feeding hopper and gradually enters the material drop gap. The drive motor drives the vertical shear column to rotate the movable shear bar, which works in conjunction with the fixed shear bar to shear and crush the material. During the process, the material continuously slides down, and the material drop gap continuously narrows as it slides down, so the material is continuously sheared and crushed. The material is sheared in the horizontal direction, and finally the crushed material falls from the discharge port and is discharged from the discharge channel.

[0008] The present invention is further configured such that an upwardly and outwardly expanding feeding hopper is provided on the upper side of the crushing cylinder, and the upper end of the vertical shearing column is a cone shape that is larger at the bottom and smaller at the top.

[0009] The present invention is further configured such that a rotating connecting frame is provided inside the feeding hopper, a limiting collar is provided in the middle of the rotating connecting frame, and a rotating shaft is provided at the upper end of the vertical shearing column, which is rotatably connected to the limiting collar.

[0010] The present invention is further configured such that each fixed shearing bar has multiple horizontal shearing openings distributed along its height direction, and each movable shearing bar has multiple horizontal shearing blocks that correspond one-to-one with the horizontal shearing openings.

[0011] The present invention is further configured such that an inclined guide plate is provided between the inner wall of the support cylinder and the outer wall of the mounting cylinder, and the lower edge of the inclined guide plate extends downward to the discharge channel.

[0012] The present invention is further configured such that a reducer connected to the power output shaft of the drive motor is provided inside the mounting cylinder, and the output shaft of the reducer is connected to the vertical shear column.

[0013] The present invention is further configured such that each fixed shear bar has a plurality of first connecting holes distributed along its height direction, and the side wall of the crushing cylinder has a plurality of first mounting holes corresponding one-to-one with the first connecting holes. Each fixed shear bar is connected to the crushing cylinder by bolts passing through the corresponding first connecting holes and first mounting holes.

[0014] The present invention is further configured such that each movable shear bar has a plurality of second connecting holes distributed along its height direction, and the outer wall of the vertical shear column has a plurality of second mounting holes corresponding one-to-one with the second connecting holes. Each movable shear bar is connected to the vertical shear column by bolts passing through the corresponding second connecting holes and second mounting holes.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Firstly, this utility model adopts a vertical feeding method, with the movable shear bar rotating and cooperating with the fixed shear bar to gradually shear and crush the material that falls by gravity, which can crush the material faster. In addition, the material is continuously sheared and crushed multiple times by the movable shear bar rotating and the fixed shear bar during the process, which can crush the material more thoroughly.

[0017] Secondly, this utility model increases the horizontal shearing function by cooperating with the horizontal shearing block and the horizontal shearing opening, so that the material is horizontally sheared and crushed during the process of falling by gravity, which helps to improve the material crushing effect.

[0024] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the shearing crushing device proposed in this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0025] Example, refer to Figure 1-5A shearing crushing device includes a crushing cylinder 1 with an open top, a vertical shearing column 2 rotatably connected inside the crushing cylinder 1, a feeding hopper 3 that expands upward and outward on the upper side of the crushing cylinder 1, the upper end of the vertical shearing column 2 being conical with a larger bottom and a smaller top, a rotating connecting frame 4 being provided inside the feeding hopper 3, a limiting collar 5 being provided in the middle of the rotating connecting frame 4, and a rotating shaft 6 rotatably connected to the limiting collar 5 being provided at the upper end of the vertical shearing column 2.

[0026] The inner wall of the crushing cylinder 1 gradually slopes downward toward the vertical shear column 2. The inner wall of the crushing cylinder 1 is connected to multiple vertically arranged and circumferentially distributed fixed shear bars 7. Each fixed shear bar 7 has multiple first connecting holes 8 distributed along its height direction. The side wall of the crushing cylinder 1 has multiple first mounting holes 9 corresponding to the first connecting holes 8. Each fixed shear bar 7 is connected to the crushing cylinder 1 by bolts passing through the corresponding first connecting holes 8 and first mounting holes 9. A material drop gap is left between every two fixed shear bars 7.

[0027] The outer side of the vertical shear column 2 is connected to multiple movable shear bars 10, each corresponding to a fixed shear bar 7. Each movable shear bar 10 has multiple second connecting holes 11 distributed along its height. The outer wall of the vertical shear column 2 has multiple second mounting holes 12 corresponding to the second connecting holes 11. Each movable shear bar 10 is connected to the vertical shear column 2 by bolts passing through the corresponding second connecting holes 11 and second mounting holes 12. Each fixed shear bar 7 has two horizontal shearing openings 13 distributed along its height. Each movable shear bar 10 has two horizontal shearing blocks 14 corresponding to the horizontal shearing openings 13. The cooperation between the horizontal shearing blocks 14 and the horizontal shearing openings 13 increases the horizontal shearing function and improves the material crushing effect.

[0028] A support cylinder 15 is connected to the lower end of the crushing cylinder 1. An installation cylinder 16 is installed inside the support cylinder 15. A drive motor 17 for driving the vertical shear column 2 is installed inside the installation cylinder 16. A reducer 18 connected to the power output shaft of the drive motor 17 is also installed inside the installation cylinder 16. The output shaft of the reducer 18 is connected to the vertical shear column 2. Multiple circumferentially distributed material discharge holes 19 are formed at the bottom of the crushing cylinder 1 between the inner wall of the crushing cylinder 1 and the outer wall of the vertical shear column 2. A discharge channel 20, communicating with the material discharge holes 19, is connected outward from the support cylinder 15. An inclined guide plate 21 is installed between the inner wall of the support cylinder 15 and the outer wall of the installation cylinder 16. The lower edge of the inclined guide plate 21 extends downward to the discharge channel 20, allowing the crushed material to be discharged from the discharge channel 20.

[0029] Working principle: The material is added into the feeding hopper 3 and gradually enters the material drop gap. The drive motor 17 drives the vertical shear column 2 to rotate the movable shear bar 10, which works with the fixed shear bar 7 to shear and crush the material. During the process, the material continuously slides down, and the material drop gap narrows continuously as it slides down, so the material is continuously sheared and crushed. At the same time, the horizontal shear block 14 and the horizontal shearing port 13 work together to shear the material in the horizontal direction. Finally, the crushed material falls from the drop port to the inclined guide plate 21 and is discharged from the discharge channel 20.

[0030] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0031] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
