Description

Technical Field

[0001] The present invention relates to the technical field of crushers, and specifically to an energy-efficient crusher. Background Art

[0002] In the fields of industrial production and resource processing, as the core equipment for material pretreatment, crushers are widely used in industries such as mining, chemical engineering, building materials, and food. Their performance directly affects the efficiency and energy consumption of subsequent production processes.

[0003] Traditional crushers generally have the following problems in the process of material handling: on the one hand, the screening link of the crushed material relies on a static screen, lacking a dynamic anti-blocking mechanism. Material particles are prone to clogging the screen holes due to adhesion or accumulation, resulting in a decrease in screening efficiency or even shutdown for cleaning, especially for materials with higher humidity or viscosity. On the other hand, unqualified large-particle materials cannot achieve automatic cyclic crushing, and need to be manually cleaned and re-fed regularly, which not only increases the labor intensity, but also easily causes material waste and low crushing efficiency. In addition, traditional discharge chutes mostly rely on gravity for natural material discharge, lacking an active material-pushing device. Materials are prone to staying in the chute, especially for materials with uneven particles, often resulting in unsmooth discharge due to accumulation, further affecting the overall production efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an energy-efficient crusher, which solves the problems that material particles are prone to clogging the screen holes due to adhesion or accumulation, unqualified large-particle materials cannot achieve automatic cyclic crushing, and the discharge is unsmooth.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: An energy-efficient crusher, comprising: A housing, a first motor is installed at the right end of the housing through a fixing frame.

The right end of the protective box is fixedly connected to a crushing box. The outer wall of the first rotating rod is connected to a second rotating rod through a first synchronous belt. The left outer wall of the second rotating rod is connected to a fourth rotating rod through a linkage assembly. Crushing rollers are fixedly connected to the outer walls of the second rotating rod and the fourth rotating rod. Both of the two crushing rollers are rotatably connected to the inner wall of the crushing box; A discharge chute, the top end of the discharge chute is fixedly connected to the bottom end of the housing. A screen plate is slidably connected to the inner periphery of the top side of the discharge chute. Padding plates are fixedly connected to both the left and right ends of the screen plate. A second motor is installed at the right end of the discharge chute through a fixing frame. The driving end of the second motor is fixedly connected to a fifth rotating rod. The top end of the fifth rotating rod is connected to the bottom end of the right padding plate through a shaking assembly. A material-pushing roller is connected to the outer wall of the fifth rotating rod through a rotating assembly.

[0006] Preferably, the material feeding assembly includes a first rotating sleeve connected to the outer wall of the first rotating rod through a connecting rod. A material feeding plate is fixedly connected to the left end of the first rotating sleeve. A second rotating sleeve is fixedly connected to the left end of the material feeding plate. The inner walls of the first rotating sleeve and the second rotating sleeve are both slidably connected to the outer wall of the crushing box.

[0007] Preferably, the linkage assembly includes a third rotating rod connected to the left outer wall of the second rotating rod through a second synchronous belt. A first spur gear is fixedly connected to the outer wall of the third rotating rod. A second spur gear is meshed with the outer wall of the first spur gear. The inner wall of the second spur gear is fixedly connected to the outer wall of the fourth rotating rod. The left end of the third rotating rod is rotatably connected to the inner wall of the protective box. The right end of the third rotating rod is rotatably connected to the left end of the crushing box.

[0008] Preferably, the shaking assembly includes a crank located at the top of the fifth rotating rod. A sliding rod is fixedly connected to the left side of the top of the crank. The outer wall of the sliding rod is slidably connected to the bottom end of the right side plate.

[0009] Preferably, support rods are fixedly connected to the inner walls of both side plates. The outer walls of multiple support rods are slidably connected to the inner wall of the housing. Springs are arranged on the outer walls of multiple support rods. One end of each of multiple springs is connected to the inner wall of the housing, and the other end of each of multiple springs is connected to the outer wall of the side plate.

[0010] Preferably, the rotating assembly includes a first bevel gear located on the outer wall of the fifth rotating rod. A second bevel gear is meshed with the front end of the first bevel gear. A material feeding roller is connected to the front end of the second bevel gear through a third synchronous belt. The material feeding roller is rotatably connected to the inner wall of the discharge chute.

[0011] Preferably, a feed hopper is fixedly connected to the top of the housing. A cover plate is rotatably connected to the rear end of the feed hopper. A handle is fixedly connected to the top of the cover plate.

[0012] Preferably, an inclined plate is fixedly connected to the bottom side of the inner wall of the discharge chute. The top end of the inclined plate is an inclined surface. A support frame is fixedly connected to the outer wall of the housing.

[0013] Preferably, it includes the following steps: Step 1: Open the cover plate and put the material into the crushing box; Step 2: Start the first motor to drive the two crushing rollers to crush the material; Step 3: The crushed material will fall onto the sieve plate. Start the second motor to make the sieve plate shake and screen the material; Step 4: The qualified material will fall into the discharge chute and be discharged through the material feeding roller and the inclined plate; Step 5: The unqualified material will remain in the housing and be returned to the crushing box for secondary crushing through the material feeding plate until it is qualified and discharged.

[0014] Preferably, in step three, after the first motor drives the first rotating rod to rotate, the first synchronous belt can drive the second rotating rod to rotate, and then the second synchronous belt drives the third rotating rod to rotate. Then, under the meshing action of the first spur gear and the second spur gear, the fourth rotating rod is driven to rotate, thereby driving the two crushing rollers to crush the material.

[0015] Working principle: After opening the cover plate through the handle, the material to be crushed is put into the crushing box. Then, the first motor is started to drive the first rotating rod to rotate. The first rotating rod can drive the second rotating rod to rotate through the first synchronous belt. When the second rotating rod rotates, it can drive the third rotating rod to rotate in the same direction through the second synchronous belt. Then, under the meshing relationship between the first spur gear and the second spur gear, the fourth rotating rod is driven to rotate in the opposite direction, so that the material can be crushed by the two crushing rollers. At the same time, when the first rotating rod rotates, it will drive the first rotating sleeve to rotate through the connecting rod. When the first rotating sleeve rotates, it will drive the material distributing plate and the second rotating sleeve to slide on the periphery of the crushing box. When the crushed material falls onto the sieve plate, the second motor is started at this time, which can drive the fifth rotating rod to rotate, and drive the sieve plate to vibrate through the crank and the sliding rod, which can prevent the material from blocking the sieve plate. The material passing through the sieve plate will fall into the discharge chute. At this time, because the second motor is in operation, it can drive the first bevel gear to rotate through the fifth rotating rod, and drive the material distributing roller to rotate through the second bevel gear and the third synchronous belt, so as to be able to dial the material concentrated in the discharge chute to the discharge port of the discharge chute, making the discharge smoother. The material that does not pass through the sieve plate will remain on the sieve plate. Due to the operation of the material distributing plate, the material remaining on the sieve plate will be dialed back into the crushing box for secondary crushing by the crushing rollers, and the cycle will continue until the material passes through the sieve plate for discharging.

[0016] The present invention provides an efficient and energy-saving crusher. It has the following beneficial effects: 1. By setting the material distributing plate, the present invention can continuously dial the material that does not pass through the sieve plate back into the crushing box, realizing a closed-loop process of crushing, screening, and re-crushing, without manual intervention, significantly improving the crushing efficiency and avoiding material waste.

[0017] 2. By driving the crank and sliding rod mechanism through the second motor, the present invention can drive the sieve plate to vibrate at a high frequency, and cooperate with the elastic support of the spring to keep the sieve holes always in a permeable state, effectively solving the problem of sieve mesh blockage caused by material adhesion or particle accumulation in traditional crushers, and ensuring the stability of the screening efficiency.

[0018] 3. Through the coordinated action of the material distributing roller and the inclined plate, on the one hand, the inclined surface of the inclined plate guides the material to gather towards the discharge port, and on the other hand, the rotation of the material distributing roller actively pushes the material to the discharge port, overcoming the problem of unsmooth discharge caused by material accumulation in the traditional discharge chute, especially suitable for materials with higher humidity or uneven particles, and improving the overall discharge efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0022] Please refer to the attached Figure 1 - attached Figure 6 , the embodiment of the present invention provides an energy-efficient crusher, including: The outer shell 1 is provided with a first motor 6 at the right end through a fixing frame. The driving end of the first motor 6 is fixedly connected with a first rotating rod 7. The outer wall of the first rotating rod 7 is rotatably connected to the inner wall of the outer shell 1. The outer wall of the first rotating rod 7 is provided with a connecting rod 8, a first rotating sleeve 9, a feeding plate 10 and a second rotating sleeve 11. The inner wall of the outer shell 1 is fixedly connected with a protective box 21. The right end of the protective box 21 is fixedly connected with a crushing box 12. The outer wall of the first rotating rod 7 is connected with a second rotating rod 14 through a first synchronous belt 13. The left outer wall of the second rotating rod 14 is connected with a fourth rotating rod 19 through a second synchronous belt 16, a third rotating rod 15, a first spur gear 17 and a second spur gear 18. The outer walls of the second rotating rod 14 and the fourth rotating rod 19 are both fixedly connected with crushing rollers 20. Both crushing rollers 20 are rotatably connected to the inner wall of the crushing box 12; Specifically, when the first rotating rod 7 rotates, it drives the first rotating sleeve 9 to rotate through the connecting rod 8, so that the feeding plate 10 and the second rotating sleeve 11 slide along the outer wall of the crushing box 12, forming an outer protection to prevent materials from entering the cavities of the outer shell 1 and the crushing box 12. At the same time, the unqualified materials after crushing are deflected towards the sieve plate 24, and the unqualified materials are automatically recycled and crushed, avoiding the idling time of the equipment caused by manual cleaning in the traditional process and reducing the ineffective energy consumption.

The crank 29 at the top end of the fifth rotating rod 35 drives the sliding rod 30 to reciprocate, pushing the right cushion plate 23 to vibrate. Through the elastic connection of the support rod 22 and the spring 25, the whole sieve plate 24 shakes, avoiding the blockage of the sieve holes by materials. The qualified materials fall through the sieve holes into the discharge chute 26 and slide to the vicinity of the discharge port along the inclined surface of the inclined plate 34; at the same time, the fifth rotating rod 35 drives the feeding roller 33 to rotate through the meshing of the first bevel gear 28 and the second bevel gear 31 and the third synchronous belt 32, actively deflecting the materials in the discharge chute 26 towards the discharge port to ensure smooth discharge. The materials that do not pass through the sieve plate 24 remain on the sieve surface. During the continuous shaking process, the feeding plate 10 continuously deflects the materials on the sieve surface back into the crushing box 12, and they are crushed twice by the crushing rollers 20 until they pass through the screening and are discharged after reaching the qualified particle size.
