Description

Technical Field

[0001] This utility model belongs to the field of sand and gravel aggregate crushing technology, and in particular relates to a sand and gravel aggregate processing and crushing device. Background Technology

[0002] In infrastructure construction fields such as building engineering, road paving, and bridge construction, sand and gravel aggregates are the most widely used basic raw materials. The uniformity and compliance of their particle size distribution directly determine the strength, density, and stability of mixtures such as concrete and mortar, which in turn affects the structural safety and service life of the entire project.

[0003] Traditional sand and gravel aggregate processing and crushing devices mostly discharge directly from the feed port after crushing and put into use immediately. However, this method leads to the mixing of materials of different particle sizes, and the finished aggregate gradation seriously fails to meet engineering standards. If rework is required, the mixed materials must be fed back into the crushing equipment for secondary crushing. This not only increases the ineffective operating load of the equipment and leads to a significant increase in motor energy consumption, but also prolongs the production cycle and reduces the overall processing efficiency due to the repeated crushing and conveying of materials. It is difficult to meet the demand for efficient and stable supply of sand and gravel aggregates for large-scale infrastructure construction. Therefore, a sand and gravel aggregate processing and crushing device is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a crushing and processing device for sand and gravel aggregates. By setting up a screening mechanism, specifically, starting a motor drives a rotating disc and an eccentric fixed shaft to rotate. The fixed shaft slides within a groove, driving a swing rod to oscillate a sector gear. The sector gear meshes with a rack, causing the screen to slide back and forth within the housing, completing the material screening. Qualified material falls into a pull-out box and is removed using a handle, while unqualified material is removed through the discharge port and can be re-crushed. This precise grading of aggregate particle size meets the requirements of different projects for aggregate gradation, reduces the impact of particle size mixing on project quality, and improves the purity of the finished aggregate. This new technology addresses the problem that most existing sand and gravel aggregate processing and crushing devices discharge directly from the feed port after crushing and are put into use immediately. However, this method leads to the mixing of materials of different particle sizes, and the finished aggregate gradation seriously fails to meet engineering standards. If rework is required, the mixed materials must be fed back into the crushing equipment for secondary crushing. This not only increases the ineffective operating load of the equipment and leads to a significant increase in motor energy consumption, but also prolongs the production cycle and reduces the overall processing efficiency due to the repeated crushing and conveying of materials. This makes it difficult to meet the problem of efficient and stable supply of sand and gravel aggregates for large-scale infrastructure construction.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a crushing device for processing sand and gravel aggregates, comprising a housing with a screen slidably connected to the inner wall of the housing, a screening mechanism disposed on the back of the housing, a reduction mechanism disposed on the top of the screen, the screening mechanism including a screening component disposed on the back of the housing, and a crushing mechanism disposed inside the housing. The screening component includes a support plate with a swing rod rotatably connected to the right side of the support plate. The swing rod has a groove, and a sector gear is fixedly connected to the bottom of the groove. A driving component is disposed on the left side of the support plate. A limiting plate is installed on the back of the screen, and a rack is installed on the back of the limiting plate. The rack meshes with the sector gear, which is semi-arc-shaped.

[0006] Furthermore, the crushing mechanism includes a second motor, which is installed on the left side of the housing. Two crushing rollers are rotatably connected to the inner wall of the housing, and the output end of the second motor on the right side is fixedly connected to the crushing roller on the back side via a coupling.

[0007] Furthermore, two gears are provided on the right side of the box, and both gears are fixedly connected to two crushing rollers. A protective shell is installed on the right side of the box, and a feed inlet is installed on the top of the box. The feed inlet is conical. The two crushing rollers are symmetrically arranged with the center point of the box as the center. A pull-out box is slidably connected to the bottom of the inner wall of the box. A handle is installed on the front of the pull-out box, and a discharge port is opened on the front of the box.

[0008] Furthermore, the deceleration mechanism includes several deceleration plates, each of which is disposed on the top of the screen. Each of the deceleration plates is internally threaded with several threaded rods, which are threaded to the top of the screen. Each of the threaded rods is externally threaded with a locking block, and each of the threaded rods has a knob installed on its top. All parts connected to the deceleration plates are identical.

[0009] Furthermore, the driving component includes a motor, which is mounted on the left side of the support plate. The output end of the motor is fixedly connected to a rotating disk via a coupling. A fixed shaft is mounted on the side of the rotating disk away from the center. The rotating disk slides and is limited by the fixed shaft and the groove on the sector gear.

[0010] This utility model has the following beneficial effects: This utility model, through the setting of a screening mechanism, specifically involves starting a motor to drive a rotating disk and an eccentric fixed shaft to rotate. The fixed shaft slides within a groove, driving a swing rod to swing a sector gear. The sector gear meshes with a rack, causing the screen to slide back and forth within the box, completing the material screening. Qualified materials fall into a pull-out box and are removed by a handle, while unqualified materials are removed through the discharge port and can be re-crushed. This precise grading of aggregate particle size meets the requirements of different projects for aggregate gradation, reduces the impact of particle size mixing on project quality, and improves the purity of the finished aggregate.

[0011] This invention incorporates a deceleration mechanism. Specifically, when material falls onto the screen, the deceleration plate extends the time the material spends on the screen, resulting in more uniform screening. Furthermore, the user can adjust the angle of the deceleration plate by rotating the screw rod clockwise according to the material's condition, causing the locking block to disengage. This allows for adjustment of the deceleration plate's angle, slowing the material's descent and extending its residence time on the screen surface. This allows fine particles to pass through the screen more fully, reduces missed particles, and improves screening accuracy.

[0017] Please see Figures 1-7As shown, this utility model is a crushing device for processing sand and gravel aggregates, including a housing 1, with a screen 111 slidably connected to the inner wall of the housing 1, a screening mechanism 2 disposed on the back of the housing 1, a reduction mechanism 3 disposed on top of the screen 111, the screening mechanism 2 including a screening component 21 disposed on the back of the housing 1, and a crushing mechanism 22 disposed inside the housing 1, the screening component 21 including a support plate 211, with a swing rod 212 rotatably connected to the right side of the support plate 211. A chute 213 is provided on the upper part, and a sector gear 214 is fixedly connected to the bottom of the chute 213. A driving component is provided on the left side of the support plate 211. A limit plate 215 is installed on the back of the screen 111, and a rack 216 is installed on the back of the limit plate 215. The rack 216 meshes with the sector gear 214, which is semi-arc-shaped. The crushing mechanism 22 includes a second motor 221, which is installed on the left side of the housing 1. Two crushing rollers 222 are rotatably connected to the inner wall of the housing 1. The output end of the second motor 221 on the right side is connected to the crushing roller 222 on the back side via a coupling. The crushing rollers 222 are fixedly connected. Two gears 223 are provided on the right side of the housing 1, and both gears 223 are fixedly connected to the two crushing rollers 222. A protective shell 224 is installed on the right side of the housing 1. A feed inlet 225 is installed on the top of the housing 1. The feed inlet 225 is conical. The two crushing rollers 222 are symmetrically arranged with the center point of the housing 1 as the center. A pull-out box 226 is slidably connected to the bottom of the inner wall of the housing 1. A handle 227 is installed on the front of the pull-out box 226. A discharge port 228 is opened on the front of the housing 1. Specifically, the starting motor 217 drives the rotating disc. Rotation of 218 and eccentric fixed shaft 219, with fixed shaft 219 sliding within slide groove 213, drives swing rod 212 to swing sector gear 214. Sector gear 214 meshes with rack 216, causing screen 111 to slide back and forth within the box, completing material screening. Qualified material falls into pull-out box 226 and is removed through handle 227, while unqualified material is removed through discharge port 228 and can be re-crushed. This precise grading of aggregate particle size meets the requirements of different projects for aggregate gradation, reduces particle size mixing affecting project quality, and improves the purity of finished aggregate.

[0018] The deceleration mechanism 3 includes several deceleration plates 311, all of which are located on top of the screen 111. Each deceleration plate 311 has several threaded rods 312 threadedly connected to its interior. Each threaded rod 312 is threadedly connected to the top of the screen 111. Each threaded rod 312 has a locking block 313 threadedly connected to its outer surface. Each threaded rod 312 has a knob 314 mounted on its top. All parts connected to the deceleration plates 311 are identical. Specifically, when material falls onto the screen 111, the deceleration plates 311 cause the material to remain on the screen 111 for a longer time, resulting in more uniform screening. Furthermore, the user can hold the knob 314 and rotate the threaded rod 312 clockwise according to the material condition, causing the locking block 313 to disengage. This allows adjustment of the angle of the deceleration plate 311, slowing the material's descent speed, extending the material's residence time on the screen 111 surface, allowing fine particles to pass through the screen more fully, reducing missed particles, and improving screening accuracy.

[0019] The driving component includes a motor 217, which is mounted on the left side of the support plate 211. The output end of the motor 217 on the right side is fixedly connected to a rotating disk 218 via a coupling. A fixed shaft 219 is mounted on the side of the rotating disk 218 away from the center. The rotating disk 218 slides and is limited by the fixed shaft 219 and the slide groove 213 on the sector gear 214.

[0020] A specific application of this embodiment is as follows: In use, the user can first start motor 221 to rotate the rear crushing roller 222. Simultaneously, the rear crushing roller 222 rotates, and the front crushing roller 222 rotates via gear 223. The two crushing rollers 222 rotate relative to each other. At this time, the sand and gravel aggregate to be crushed can be poured into the box 1 through the feed inlet 225. It will first be aligned and crushed under the relative rotation of the two crushing rollers 222. Simultaneously, the crushed sand and gravel aggregate will fall into the box 1 and onto the top of the screen 111. Then, motor 217 can be started to rotate the rotating disk 218. When the rotating disk 218 rotates, it will drive the fixed shaft 219 to rotate, and the fixed shaft 219 rotates eccentrically. The rotating disk 218 slides within the groove 213 via the fixed shaft 219, thereby driving the swing rod 212 to swing the sector gear 214. Since the sector gear 214 meshes with the rack 216, it will drive the screen... The screen 111 slides back and forth inside the box to screen the material. At this time, qualified material falls into the bottom pull-out box 226. The user can take out the material inside the pull-out box 226 through the handle 227. Unqualified material after screening can be taken out through the feed port 228 for re-crushing. At the same time, when the material falls on the screen 111, it will stay on the screen 111 for a longer time under the action of the deceleration plate 311, making the screening more uniform. The user can hold the knob 314 and rotate the threaded rod 312 clockwise according to the material condition to make the locking block 313 fall off. At this time, the angle of the deceleration plate 311 can be adjusted. After the adjustment is completed, the threaded rod 312 can be rotated counterclockwise to lock the deceleration plate 311. In this application, the control of motor 1 217 and motor 2 221 can be achieved by using the program set in the control panel and inputting relevant parameters according to the requirements for automatic control. The setting of this control method can be achieved by existing technology, such as PLC.
