Description

Technical Field

[0001] This utility model belongs to the technical field of sand and gravel crushers, specifically referring to a sand and gravel crusher for civil engineering construction. Background Technology

[0002] A sand and gravel crusher is a mechanical device used to crush large rocks, ores, or other hard materials into smaller particles. It is widely used in industries such as mining, construction, and road building. Existing sand and gravel crushers used in civil engineering projects can more efficiently prepare for subsequent crushing operations by incorporating a pre-treatment process.

[0003] In the sand and gravel crushing equipment used in civil engineering construction, there is a risk of material jamming in the pretreatment stage of the existing technology. If sand and gravel accumulate and become jammed in the pretreatment chamber of the existing sand and gravel crushing equipment, it will cause more and more sand and gravel to accumulate in the pretreatment chamber and the feed hopper, which can easily lead to accidents such as overflow of sand and gravel raw materials and equipment damage.

[0004] When material jamming occurs, the lack of auxiliary material discharge function increases the trouble of equipment maintenance and raw material cleaning and transfer. Utility Model Content

[0005] The technical problem this utility model aims to solve is that the sand and gravel crusher used in civil engineering construction has a risk of material jamming during the pretreatment process, which affects continuous processing and use, and lacks auxiliary functions after material jamming.

[0006] The technical solution adopted by this utility model is as follows:

[0007] This utility model proposes a sand and gravel crusher for civil engineering construction, including a crusher shell. Two sets of motors are inserted through the side wall of the crusher shell. Crushing rollers are fixedly connected to the output shaft of the motors and rotate inside the crusher shell. The two sets of crushing rollers rotate in opposite directions. The model also includes a pretreatment unit located above the crusher shell. The pretreatment unit includes a feeding shell. Slides are fixedly connected to the upper parts of both sides of the feeding shell. A slide platform is slidably provided on the slide platform. A variable diameter cavity is inserted through the slide platform. The variable diameter cavity has an inverted conical structure that is wider at the top and narrower at the bottom.

[0008] Furthermore, a second motor is fixedly connected to one side of the unloading machine housing, and an eccentric block for intermittently pushing the slide is fixedly connected to the output shaft of the second motor.

[0009] Furthermore, a connecting frame is fixedly connected to one end of the slide away from the eccentric block, and a spring for elastically restoring the slide is fixedly connected to the connecting frame.

[0010] Furthermore, a support base is fixedly connected to the lower part of the feeding machine housing and mounted on the upper part of the crusher housing. A sliding groove is provided on the upper inner side of the support base, and a screen equipment frame is slidably mounted on the sliding groove. A detachable screen is movably inserted and removed from the screen equipment frame.

[0011] Furthermore, an emergency discharge housing is provided on the lower part of the side wall of the feeding machine housing, and an inclined guide groove is connected to the emergency discharge housing. A baffle plate is movably inserted and plugged into the upper part of the emergency discharge housing.

[0012] Furthermore, a U-shaped frame located above the emergency discharge machine housing is fixedly connected to the outer wall of the feeding machine housing. An electric push rod passes through the U-shaped frame, and a connecting block for pulling the baffle plate is fixedly connected to the output end of the electric push rod.

[0013] The beneficial effects of this utility model by adopting the above structure are as follows:

[0014] 1. A pre-treatment unit is set up to pre-treat the materials. The variable diameter cavity improves the overall material flow efficiency and reduces the probability of material jamming. With the help of the motor-driven eccentric block, high-frequency vibration is used to clear blockages.

[0015] 2. Additionally, it features an emergency discharge casing that can be opened and closed. In case of material jamming before the screening stage, it can assist in discharge, reducing the hassle of subsequent maintenance and cleaning. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0023] Example 1:

[0024] like Figure 1 , Figure 2 As shown, the present invention proposes a sand and gravel crusher for civil engineering construction, including a crusher shell 1. Two sets of motors 11 are inserted through the side wall of the crusher shell 1. Crushing rollers 12 are fixedly connected to the output shaft of the motors 11 and rotate inside the crusher shell 1. The two sets of crushing rollers 12 rotate towards each other. The invention also includes a pretreatment unit located above the crusher shell 1. The pretreatment unit includes a feeding shell 2. Slide frames 21 are fixedly connected to the upper parts of both sides of the feeding shell 2. A slide table 22 is slidably provided on the slide frame 21. A variable diameter cavity 23 is inserted through the slide table 22. The variable diameter cavity 23 has an inverted conical structure that is wider at the top and narrower at the bottom.

[0025] The crushing roller 12 is driven by motor 11 to crush the sand and gravel. Before crushing, the material can be pre-treated by the pre-treatment unit. The material is fed into the feeder housing 2 through the variable diameter cavity 23. During the downward flow of the material, the inverted cone-shaped cavity can use the material's own gravity to generate a gradually increasing downward force, which promotes the material to slide down faster and reduces the adhesion and accumulation of material on the cavity wall. Compared with the traditional straight cylindrical cavity, the inverted cone design effectively avoids the formation of a stagnation zone in the vertical cavity wall. The material can flow more smoothly to the bottom, thereby significantly improving the overall material flow efficiency of the pre-treatment cavity and reducing the probability of material jamming.

[0026] like Figure 3 As shown, a second motor 3 is fixedly connected to one side of the unloading machine housing 2. An eccentric block 31 for intermittently pushing the slide table 22 is fixedly connected to the output shaft of the second motor 3. A connecting frame 4 is fixedly connected to one end of the slide frame 21 away from the eccentric block 31. A spring 41 for elastically restoring the slide table 22 is fixedly connected to the connecting frame 4.

[0027] The eccentric block 31 is driven to rotate by the motor 23, intermittently contacting the slide table 22 and pushing it to slide on the slide 21. It is then reset by the spring 41, achieving continuous vibration, high-frequency oscillation to clear blockages and loosen accumulated materials.

[0028] like Figure 3 , 4 As shown, a support base 5 is fixedly connected to the lower part of the feeding machine housing 2 and mounted on the upper part of the crusher housing 1. A sliding groove 51 is provided on the upper inner side of the support base 5. A screen device frame 52 is slidably mounted on the sliding groove 51. A detachable screen 53 is movably inserted and removed from the screen device frame 52. The detachable screen 53 is located below the feeding machine housing 2 to screen materials, separate large particles, and is easy to disassemble and maintain.

[0029] Example 2:

[0030] like Figure 1 , 3 As shown, an emergency discharge housing 6 is provided on the lower part of the side wall of the feeding machine housing 2. An inclined guide groove 61 is connected to the emergency discharge housing 6, and a baffle plate 62 is movably inserted and removed from the upper part of the emergency discharge housing 6.

[0031] A U-shaped frame 7 is fixedly connected to the outer wall of the feeding machine housing 2, located above the emergency discharge machine housing 6. An electric push rod 71 passes through the U-shaped frame 7, and a connecting block 72 for pulling the baffle plate 62 is fixedly connected to the output end of the electric push rod 71.

[0032] In actual use, if a material jam occurs, the material will start to accumulate from the bottom of the feeder housing 2. At this time, by controlling the output end of the electric push rod 71 to retract, the connecting block 72 will pull the baffle plate 62 upward. After opening the emergency discharge housing 6, the material will be discharged from the guide chute 61 for emergency discharge, avoiding the impact on equipment maintenance and cleaning. The specific model of the electric push rod 71 is DYT-10kN.

[0033] The above is the entire usage process of a sand and gravel crusher for civil engineering construction.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.

[0035] Unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components.
