Description

Technical Field

[0001] This application relates to the field of crusher technology, and more specifically, to an automatic discharge crusher. Background Technology

[0002] Automatic discharge stone crusher is a stone crushing equipment that integrates crushing, screening and automatic discharge functions. It crushes large stones into small stones of the required size through mechanical devices, uses a built-in screening system to screen out finished stones that meet the particle size requirements, and automatically transports them to the designated location. It features high production efficiency, large crushing ratio, uniform finished product particle size and high degree of automation, and is widely used in construction, road, mining and other industries.

[0003] During the crushing process, larger or harder stones may not be effectively crushed, resulting in poor crushing quality and requiring repeated crushing operations, severely impacting crushing efficiency. In the discharge stage, crushed stones often accumulate inside the crushing chamber, requiring manual cleaning and handling by workers. This not only consumes significant manpower and time, increasing labor costs, but also poses substantial safety hazards as workers need to be in close contact with the equipment during manual cleaning.

[0004] In view of this, this application proposes an automatic discharge crusher. Utility Model Content

[0005] The purpose of this application is to provide an automatic discharge crusher that solves the technical problems mentioned in the background art.

[0006] This application provides an automatic discharge stone crusher, including a stone crushing cylinder. A feeding mechanism is provided below the stone crushing cylinder, and a crushing frame is fixedly connected to the upper part of the inner wall of the stone crushing cylinder. A crushing mechanism is provided inside the stone crushing cylinder, which can crush large stones into small stones. The crushing mechanism includes a crushing head located at the lower part of the inside of the stone crushing cylinder, and the crushing head is in a conical inclined shape. An extension block is fixedly connected to the lower end of the crushing head, and a bevel gear disk is fixedly connected to the lower end of the extension block.

[0007] Optionally, the feeding mechanism includes a transport frame located below the crushing cylinder, with multiple conveying rollers rotatably connected inside the transport frame, and a conveyor belt drivingly connected to the outer wall of the multiple conveying rollers.

[0008] Optionally, a motor is fixedly connected to the rear of one end of the transport frame, and the output end of the motor is fixedly connected to a conveyor roller on one side.

[0009] Optionally, a fixing block is rotatably connected to the lower end face of the bevel gear disk, and a pair of support rods are fixedly connected to the outer wall of the fixing block, with one end of the support rods fixedly connected to the inner wall of the crushing cylinder.

[0010] Optionally, a bevel gear block meshes with one side below the bevel gear disk, one end of the bevel gear block is fixedly connected to a drive shaft, and one end of the drive shaft extends out of the crushing cylinder and is rotatably connected to the crushing cylinder.

[0011] Optionally, a transmission block is provided at the front of one end of the transport frame, and one end of the transmission block is fixedly connected to a conveying roller on one side. A transmission belt is connected to the outer wall between the transmission block and the transmission shaft, and a feed ring is fixedly connected to the upper end face of the crushing frame.

[0012] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0013] This application designs the crushing head at an angle, with the distance between the inclined surface of the inner wall of the crushing frame and the outer wall of the crushing head gradually decreasing. Driven by the transmission shaft and rotated via the bevel gear block, bevel gear disc, and extension block, it efficiently crushes stones stuck between the crushing frame and itself, breaking large stones into smaller pieces. This crushing method is stable and efficient, adaptable to stones of different sizes and hardness, and effectively improves the quality and efficiency of crushing.

[0014] Secondly, the motor drives the conveyor rollers and conveyor belt on one side of the transport frame to rotate, while the conveyor rollers simultaneously drive the transmission block, transmission belt, and transmission shaft to rotate synchronously. This ensures that after the stones are crushed into small pieces, they can fall promptly from inside the crushing cylinder onto the moving conveyor belt and be smoothly moved out from under the crushing cylinder. The combination of synchronous crushing and synchronous transport achieves an automated discharge process. Workers no longer need to manually clean the stones from inside the crushing cylinder, saving manpower and improving work safety. At the same time, this automatic discharge method allows the entire stone crushing operation to continue continuously, greatly improving production efficiency and reducing the production cycle.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-3 This application provides an automatic discharge stone crusher, including a crushing cylinder 1. A feeding mechanism is located below the crushing cylinder 1. A crushing frame 10 is fixedly connected to the upper part of the inner wall of the crushing cylinder 1. A crushing mechanism is located inside the crushing cylinder 1, which can crush large stones into smaller stones. The crushing mechanism includes a crushing head 16 located at the lower part of the crushing cylinder 1. The crushing head 16 is conical and inclined. An extension block 15 is fixedly connected to the lower end of the crushing head 16. A bevel gear disk 14 is fixedly connected to the lower end of the extension block 15. The distance between the inclined surface of the inner wall of the crushing frame 10 and the outer wall of the crushing head 16 gradually decreases. When the crushing head 16 rotates, it can efficiently squeeze the stones stuck between the crushing frame 10 and itself, crushing large stones into smaller pieces. This crushing method is stable and efficient, can adapt to stones of different sizes and hardness, and effectively improves the quality and efficiency of crushing.

[0021] The feeding mechanism includes a conveyor frame 2 located below the crushing cylinder 1. Multiple conveyor rollers 6 are rotatably connected inside the conveyor frame 2. A conveyor belt 7 is driven to the outer wall of the multiple conveyor rollers 6. After the stones are crushed into small pieces, they can fall from inside the crushing cylinder 1 onto the moving conveyor belt 7 in a timely manner and be smoothly moved out from below the crushing cylinder 1 by the conveyor belt 7.

[0022] A motor 3 is fixedly connected to the rear of one end of the transport frame 2. The output end of the motor 3 is fixedly connected to a conveying roller 6 on one side. A fixing block 13 is rotatably connected to the lower end face of the bevel gear disk 14. A pair of support rods 12 are fixedly connected to the outer wall of the fixing block 13, and one end of the support rods 12 is fixedly connected to the inner wall of the crushing cylinder 1. A bevel gear block 9 meshes with one side below the bevel gear disk 14. A drive shaft 8 is fixedly connected to one end of the bevel gear block 9, and one end of the drive shaft 8 extends out of the crushing cylinder 1 and is rotatably connected to the crushing cylinder 1. A drive block 4 is provided at the front of one end of the transport frame 2. One end of the transmission block 4 is fixedly connected to the conveyor roller 6 on one side. A transmission belt 5 is connected to the outer wall between the transmission block 4 and the transmission shaft 8. A feed ring 11 is fixedly connected to the upper end face of the crushing frame 10. The motor 3 drives the conveyor roller 6 and the conveyor belt 7 on one side inside the transport frame 2 to rotate. At the same time, the conveyor roller 6 drives the transmission block 4, the transmission belt 5 and the transmission shaft 8 to rotate synchronously. Driven by the transmission shaft 8, the transmission is driven by the bevel gear block 9, the bevel gear disc 14 and the extension block 15. The combination of synchronous crushing and synchronous transport realizes an automated discharge process. The staff does not need to manually clean the stones in the crushing cylinder 1, which saves manpower and improves work safety. At the same time, this automatic discharge method allows the entire stone crushing work to be carried out continuously, which greatly improves production efficiency and reduces the production cycle.

[0023] Working principle: When large stones need to be crushed into smaller stones, the operator first starts the motor 3. The motor 3 drives the output end to rotate, which in turn drives the conveyor roller 6 on one side of the conveyor frame 2 to rotate. The rotation of the conveyor roller 6 drives the conveyor belt 7 and several other conveyor rollers 6 to rotate synchronously. The rotation of the conveyor roller 6 on one side also drives the transmission block 4 to rotate. The rotation of the transmission block 4 drives the transmission belt 5 and the transmission shaft 8 on the crushing cylinder 1 to rotate synchronously. The rotation of the transmission shaft 8 drives the bevel gear block 9 to rotate. Since the bevel gear block 9 meshes with the bevel gear disk 14 on the fixed block 13, the rotation of the bevel gear block 9 drives the bevel gear disk 14 to rotate synchronously. The rotation of the bevel gear disk 14 drives the upper extension block 15 and the crushing head 16 to rotate synchronously.

[0024] Workers pour large stones into the crushing cylinder 1 through the feed ring 11. The distance between the inclined surface of the inner wall of the crushing frame 10 and the outer wall of the crushing head 16 gradually decreases. Since the crushing head 16 is cut at an angle, it will squeeze the stones stuck between the crushing frame 10 and the crushing head 16 during rotation, thereby crushing the stones. The crushed stones fall out of the crushing cylinder 1 and onto the moving conveyor belt 7. The conveyor belt 7 moves the stones out of the bottom of the crushing cylinder 1 for easy collection by workers.
