Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dry mortar production technology, and in particular relates to a multi-stage crushing equipment for dry mortar production. Background Technology
[0002] In the production of dry mortar, it is usually necessary to crush materials such as sand and gravel. Traditional crushing equipment usually uses crushing rollers to crush the material when crushing sand and gravel. However, this method only crushes the material once, resulting in poor crushing effect. Not only does it require reprocessing of the crushed material, but it also needs to be screened to separate larger particles, which increases the complexity of the workflow. Utility Model Content
[0003] The purpose of this utility model is to provide a multi-stage crushing equipment for dry mortar production. By setting up crushing components, specifically through multi-stage crushing, the material can be ground into finer particles more evenly, thus eliminating the need for subsequent rework and improving the crushing effect. This solves the problem that traditional crushing devices usually use crushing rollers to squeeze and crush materials when crushing sand and gravel, but the crushing effect is poor after only one crushing, requiring the crushed material to be reworked.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model relates to a multi-stage crushing device for dry mortar production, comprising a base, a crushing box fixedly connected to the top of the base, a feed hopper fixedly connected to the top of the crushing box, a motor fixedly connected to the right side of the crushing box, and a crushing assembly inside the crushing box. The crushing assembly includes a crushing chamber fixedly connected to the top of the inner wall of the crushing box, a grinding chamber fixedly connected to the bottom of the crushing chamber, and a grinding chamber fixedly connected to the bottom of the grinding chamber. A rotating rod is installed inside the crushing box, with several crushing rods fixedly connected to its outer surface. Several fixed rods are fixedly connected to the inner wall of the crushing box. Two grinding rollers are rotatably connected inside the grinding chamber, and a grinding roller is rotatably connected inside the grinding chamber. The bottom of the grinding chamber is conical, and the top and bottom of the grinding rollers are both conical surfaces. The crushing rods are welded onto the rotating rod, and the fixed rods are welded to the inner wall of the crushing box. The crushing box, grinding chamber, and grinding chamber constitute three stages of crushing, improving the crushing effect.
[0006] Furthermore, a fixed seat is fixedly connected to the right side of the inner wall of the feed hopper, a baffle is fixedly connected to the top of the fixed seat, a fixed plate is fixedly connected to the inner wall of the baffle, a second motor is fixedly connected to the top of the fixed plate, and a third gear is fixedly connected to the bottom output end of the second motor; the baffle is used to shield and protect the internal structure, so as to prevent the material from affecting the internal structure.
[0007] Furthermore, the top of the rotating rod passes through the fixed seat and extends into the baffle, and the rotating rod is rotatably connected to the fixed seat. A second gear is fixedly connected to the top of the rotating rod, and the second gear meshes with a third gear. The fixed rod is located below the crushing rod. Two first gears are arranged on the left side of the crushing box. The left sides of the two crushing rollers are fixedly connected to the right sides of the two first gears, and the two first gears mesh with each other. The left output end of the motor is fixedly connected to the right side of the crushing roller located behind it via a coupling. The bottom of the crushing box is triangular in shape to facilitate the subsequent discharge of crushed materials into the grinding box.
[0008] Furthermore, a motor three is fixedly connected to the right side of the grinding box, a gear four is fixedly connected to the top output end of the motor three, several connecting posts are fixedly connected to the top of the grinding roller, a gear ring is fixedly connected to the top of the connecting posts, a limit ring is rotatably connected to the inner ring of the gear ring, the top of the limit ring is fixedly connected to the top of the inner wall of the grinding box, and the gear ring meshes with the gear four; the limit ring is used to limit the position of the gear ring, so that the position of the gear and the grinding roller will not be offset, and improves the stability during rotation.
[0009] Furthermore, several hemispherical protrusions are fixedly connected to the top conical surface of the grinding roller, and a fixed column is fixedly connected to the top of the inner wall of the grinding box. The fixed column has a hollow interior, and an inner telescopic rod is slidably connected to the center of the bottom of the fixed column. A collision block is fixedly connected to the bottom of the inner telescopic rod, and a spring is installed inside the fixed column. The bottom of the collision block is hemispherical, and the bottom of the spring is fixedly connected to the top of the inner telescopic rod, and the top of the spring is fixedly connected to the top of the inner wall of the fixed column. When the hemispherical protrusion contacts the collision block, it pushes the collision block upward, causing the inner telescopic rod to slide inside the fixed column and compressing the spring, allowing the hemispherical protrusion to pass smoothly through the collision block.
[0010] This utility model has the following beneficial effects:
[0011] 1. This utility model, by setting up a crushing component, specifically, uses a crushing rod in cooperation with a fixed rod to crush the incoming material, breaking larger particles into smaller pieces. Then, two crushing rollers grind the smaller pieces into even smaller particles. Subsequently, the grinding rollers, in cooperation with the bottom of the inner wall of the grinding chamber, grind the fine particles into even finer particles, thereby achieving the purpose of crushing. This method, through multi-stage crushing, enables the material to be ground into finer particles more evenly, thus eliminating the need for subsequent rework and improving the crushing effect.
[0012] 2. This utility model incorporates a collision block. Specifically, when the grinding roller rotates, the hemispherical protrusions on the grinding roller will contact and collide with the collision block, causing the grinding roller to vibrate. Through continuous collision, the grinding roller will continuously vibrate, which can assist in material discharge, reduce adhesion, and prevent clogging.
[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The crushing rod 212, in cooperation with the fixed rod 213, crushes the incoming material, breaking larger particles into smaller pieces. Then, the two crushing rollers 221 crush the smaller pieces into even smaller particles. Subsequently, the grinding roller 231, in cooperation with the bottom of the inner wall of the grinding chamber 123, grinds the fine particles into even finer particles, thereby achieving the purpose of pulverization. This method, through multi-stage pulverization, enables the material to be ground into finer particles more evenly, thus eliminating the need for subsequent rework and improving the pulverization effect.
[0026] A fixed base 13 is fixedly connected to the right side of the inner wall of the feed hopper 111. A baffle 131 is fixedly connected to the top of the fixed base 13. A fixed plate 132 is fixedly connected to the inner wall of the baffle 131. A motor 133 is fixedly connected to the top of the fixed plate 132. A gear 134 is fixedly connected to the bottom output end of the motor 133.
[0027] The top of the rotating rod 211 passes through the fixed seat 13 and extends into the baffle 131. The rotating rod 211 is rotatably connected to the fixed seat 13. A gear 214 is fixedly connected to the top of the rotating rod 211. The gear 214 meshes with the gear 3 134. The fixed rod 213 is located below the crushing rod 212. Two gears 113 are arranged on the left side of the crushing box 11. The left sides of the two crushing rollers 221 are fixedly connected to the right sides of the two gears 113 respectively. The two gears 113 mesh with each other. The left output end of the motor 112 is fixedly connected to the right side of the crushing roller 221 located behind it through a coupling.
[0028] A motor 14 is fixedly connected to the right side of the grinding box 123. A gear 141 is fixedly connected to the top output end of the motor 14. Several connecting posts 232 are fixedly connected to the top of the grinding roller 231. A gear ring 233 is fixedly connected to the top of the connecting posts 232. A limit ring 234 is rotatably connected to the inner ring of the gear ring 233. The top of the limit ring 234 is fixedly connected to the top of the inner wall of the grinding box 123. The gear ring 233 is meshed with the gear 141.
[0029] Several hemispherical protrusions 235 are fixedly connected to the top conical surface of the grinding roller 231. A fixed column 15 is fixedly connected to the top of the inner wall of the grinding box 123. The fixed column 15 has a hollow interior. An inner telescopic rod 151 is slidably connected to the bottom center of the fixed column 15. A collision block 152 is fixedly connected to the bottom of the inner telescopic rod 151. A spring 153 is installed inside the fixed column 15. The bottom of the collision block 152 is hemispherical. The bottom of the spring 153 is fixedly connected to the top of the inner telescopic rod 151, and the top of the spring 153 is fixedly connected to the top of the inner wall of the fixed column 15. When the grinding roller 231 rotates, the hemispherical protrusions 235 on the grinding roller 231 will contact and collide with the collision block 152, causing the grinding roller 231 to produce a certain vibration effect. Through continuous collision, the grinding roller 231 will continuously produce a vibration effect, which can assist in material discharge, reduce adhesion, and prevent clogging.
[0030] One specific application of this embodiment is:
[0031] In operation, motors 112, 133, and 14 are started simultaneously. Motor 133 drives gear 134 to rotate, which in turn drives the rotating rod 211 to rotate via gear 214. The crushing rod 212 then rotates accordingly. Motor 112 drives the rear crushing roller 221 to rotate, which, through the action of the two gears 113, causes the front crushing roller 221 to rotate in the opposite direction. Motor 14 drives gear 141 to rotate, which in turn drives the gear ring 233 to rotate. The gear ring 233, through the connecting column 232, drives the grinding roller 231 to rotate. The material to be crushed is then fed into the crushing box 121 through the feed hopper 111. The crushing rod 212 then rotates along the fixed rod 21. The material is crushed by the combination of three grinding rollers 121 and 23. Larger particles are broken into smaller pieces, which then enter the crushing chamber 122. Two grinding rollers 221 crush the smaller pieces into even smaller particles, which then enter the grinding chamber 123. Since the top of the grinding roller 231 is conical, particles leak from the side of the grinding roller 231 to the bottom. The grinding roller 231, through its interaction with the bottom of the inner wall of the grinding chamber 123, grinds the fine particles into even finer particles, thus achieving the purpose of pulverization. Finally, the pulverized material is discharged from the bottom of the grinding chamber 123. This method, through multi-stage pulverization, enables the material to be ground into finer particles more evenly, thus eliminating the need for subsequent rework and improving the pulverization effect.
[0032] Simultaneously, when the grinding roller 231 rotates, the hemispherical protrusion 235 on the grinding roller 231 will contact and collide with the collision block 152, causing the grinding roller 231 to generate a certain vibration effect. This will push the collision block 152 upward, causing the inner telescopic rod 151 to slide within the fixed column 15 and compress the spring 153, allowing the hemispherical protrusion 235 to pass smoothly through the collision block 152. When the collision block 152 leaves the hemispherical protrusion 235, the inner telescopic rod 151 will be pushed downward by the elastic action of the spring 153, causing the collision block 152 to reset, facilitating the next collision. Finally, through continuous collision, the grinding roller 231 will continuously generate a vibration effect, which can assist in material discharge, reduce adhesion, and prevent clogging problems.
