Description

Technical Field

[0001] This utility model relates to the field of hammer crusher technology, specifically a hammer crusher with a graded crushing adjustment function. Background Technology

[0002] Crushing equipment, as the main equipment in mining, is primarily used for crushing stones of varying sizes. Multiple models of crushers can be selected based on the required output. The stone falls directly from the top of the machine into the high-speed rotating hammers. Under the action of high-speed centrifugal force, the stone impacts, rubs, and is crushed by the hammers. During the crushing process, it also collides at high speed and undergoes high-density crushing with flying stones that are diverted in an umbrella-like manner around the hammers. After mutual impact, the stone is discharged directly from the bottom, forming a closed-loop multi-cycle process. The required particle size is controlled by screening equipment.

[0003] Currently, existing hammer crushers can only crush materials of a specific size. If the material is too large, some smaller crushers cannot crush it, making it impossible to classify and crush materials of different sizes. When large and small materials are crushed together, the crushing effect is poor, affecting the crushing efficiency. Furthermore, if large materials are fed into a smaller crusher, the hammer cannot effectively crush them, which may damage the crusher. Therefore, we propose a hammer crusher with a graded crushing adjustment function. Utility Model Content

[0014] 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.

[0015] Please see Figures 1 to 4 This utility model provides a technical solution: a hammer crusher with a grading and crushing adjustment function, including a crushing box 1. Several partitions 2 are fixedly installed inside the crushing box 1, dividing the interior of the crushing box 1 into several crushing chambers. Two first mounting shafts 3 are rotatably installed inside the top of the crushing box 1. Conical guide rollers 4 are fixedly installed on the outer sides of both first mounting shafts 3. A V-shaped material leakage gap exists in the middle of the two conical guide rollers 4. One end of each conical guide roller 4 extends to the outer side of the crushing box 1 and is fixedly installed with a transmission gear 5. A first reduction motor 6 is fixedly installed on one side of the crushing box 1, and the output end of the first reduction motor 6 is fixedly connected to one end of a conical guide roller 4. The crusher allows the material to be crushed to pass through the crushing box 1 into a series of chambers. After the material is fed into the crushing chamber 1 above the position where the gap between the two conical guide rollers 4 is smaller, the first reduction motor 6 is turned on to drive one conical guide roller 4 and the transmission gear 5 to rotate. After the transmission gear 5 rotates, it meshes with the other transmission gear 5, thereby driving the other conical guide roller 4 to rotate at the same time. The material can be conveyed by the two conical guide rollers 4, so that the material moves on its outside. At the same time, the material to be crushed can automatically adjust according to the gap between the middle of the two conical guide rollers 4 and fall into different crushing chambers for crushing, so as to achieve graded crushing. The material is crushed by crushing hammers 10 of different specifications in several crushing chambers. A control panel is set on one side of the crushing chamber 1, and the bottom of the crushing chamber 1 is set with support legs.

[0016] Inside the crushing box 1, on one side of several partitions 2, a second mounting shaft 7 is rotatably installed. Several hammer discs 8 are fixedly installed on the outside of the second mounting shaft 7. Several hammer head shafts 9 are fixedly installed inside the hammer discs 8. Several breaker hammers 10 are movably installed on the outside of the hammer head shafts 9. An arc-shaped mesh plate 11 is fixedly installed inside the crushing box 1 on one side of several partitions 2. The breaker hammers 10 cooperate with the arc-shaped mesh plate 11. Through the arrangement of the second mounting shaft 7, hammer discs 8, hammer head shafts 9 and breaker hammers 10, the rotation of the second mounting shaft 7 drives the hammer discs 8, hammer head shafts 9 and breaker hammers 10 to rotate. The breaker hammers 10 rotate by inertia, which can knock the input material and crush the material. The crushed material is discharged through the arc-shaped mesh plate 11.

[0017] Inclined guide plates 18 are fixedly installed on the inner wall of the crushing box 1 and above the two conical guide rollers 4. The inclined guide plates 18 can guide the material fed into the crushing box 1 so that the material can fall to the middle of the two conical guide rollers 4 and be conveyed by the conical guide rollers 4.

[0018] The crushing box 1 has a discharge port 19 on one side, and the conical guide roller 4 cooperates with the discharge port 19. The discharge port 19 can discharge the accumulated material when the material is fed in too fast and cannot be discharged, and can also discharge some materials that are too large to be crushed.

[0019] One end of each of several second mounting shafts 7 extends to the outside of the crushing box 1 and is fixedly mounted with a driven pulley 12. Mounting plates 13 are fixedly mounted on the bottom of both sides of the crushing box 1. Several second reduction motors 14 are fixedly mounted on the top of the mounting plates 13. A drive pulley 15 is fixedly mounted on the output end of the second reduction motor 14. A transmission belt 16 is sleeved on the outside of the driven pulley 12 and the drive pulley 15. By turning on the second reduction motor 14, the drive pulley 15 is driven to rotate, which in turn drives the driven pulley 12 and the second mounting shaft 7 to rotate through the transmission belt 16, thereby driving the second mounting shaft 7 to rotate and crush the material.

[0020] A feeding hopper 17 is fixedly installed at the bottom of the crushing box 1 and below several partitions 2. The feeding hopper 17 can guide the material that has been crushed and screened by the arc screen 11 to be discharged through the feeding hopper 17. The material can be received by setting a receiving hopper below several feeding hoppers 17.

[0021] In summary, this hammer crusher with grading and crushing adjustment function operates by first activating the first reduction motor 6 to drive one conical guide roller 4 and the transmission gear 5 to rotate. After rotating, the transmission gear 5 meshes with another transmission gear 5, thereby driving the other conical guide roller 4 to rotate simultaneously. Then, the second reduction motor 14 is activated to drive the drive pulley 15 to rotate. The drive pulley 15, through its outer transmission belt 16, drives the driven pulley 12 and the second mounting shaft 7 to rotate, thus driving the second mounting shaft 7 to rotate, which in turn drives the hammer disc 8, hammer shaft 9, and crushing hammer 10 to rotate, thus crushing... The crusher 10 rotates due to its rotational inertia, and finally feeds the material to be crushed from above the crushing box 1 onto the conical guide roller 4 and inclined guide plate 18 inside the crushing box 1. The material is conveyed by the two conical guide rollers 4, causing the material to move on its outer side. While moving, the material to be crushed can automatically adjust according to the gap between the two conical guide rollers 4 and fall into different crushing chambers for crushing, thus achieving graded crushing. The material is crushed by crushers 10 of different specifications in several crushing chambers, and the crushed material is discharged through the discharge hopper 17, thus completing the graded crushing.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
