Description

Technical Field

[0001] This utility model relates to the field of feeding components, specifically a feeding component for a crusher. Background Technology

[0002] A crusher is a machine that crushes large solid raw materials to the required size. A crusher consists of coarse crushing, fine crushing, and conveying devices, and achieves its purpose by high-speed impact.

[0003] According to publicly available patent CN220328880U, a pulverizer feeding mechanism includes a feeding assembly, a heating assembly, a pulverizing assembly, and a collecting assembly. The feeding assembly includes a processing chamber with an internal space. A feeding pipe is located at the top of the processing chamber, and a feeding pipe is located at the bottom of the processing chamber. A support frame is located at the bottom of the processing chamber. The heating assembly includes a rotary motor, which is bolted to the top of the processing chamber. A rotating shaft is located at the bottom of the rotary motor, and a stirring blade is fixed to the outer wall of the rotating shaft by a set screw. Heating plates are bolted to the outer walls of both sides of the stirring blade. The pulverizing assembly includes a pulverizing chamber with an internal space and an opening at the bottom. The bottom of the support frame is bolted to the top of the pulverizing chamber. A feeding pipe passes through the top of the pulverizing chamber. A drive motor is located on one side of the outer wall of the pulverizing chamber, and a transmission shaft is located on one side of the drive motor. A pulverizing blade is located on the outer wall of the transmission shaft.

[0004] In traditional crushers, the feeding assembly uses crushing blades at the feed inlet to crush materials. However, after crushing, an additional filtration structure is needed to filter the material. This internal filtration occupies storage space within the crusher. Furthermore, the heating method uses fixed heating elements, which can only heat a single location. This uneven heating during crushing results in uneven heating of the material in different positions. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a pulverizer feeding component to solve the problem of the current traditional pulverizer feeding components, which use pulverizing blades to pulverize materials at the feed inlet. However, after the materials are pulverized, an additional filter structure is required to filter the pulverized materials. Setting up a filter structure inside the pulverizer will occupy the internal storage space of the pulverizer. Moreover, in terms of heating, the heating element is used, but the heating element is fixed in position and can only heat from a single position. During the pulverization process, the fixed heating element heats the materials in different positions, resulting in uneven heating of the materials.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a feeding assembly for a crusher is designed, including a feeding frame, a hopper connected to the bottom of the feeding frame, a dual-shaft motor installed on the side of the feeding frame, a first rotating rod connected to one end of the dual-shaft motor, the first rotating rod extending into the feeding frame, a plurality of crushing blades installed on the outside of one end of the first rotating rod located inside the feeding frame, and a second rotating rod connected to the other end of the dual-shaft motor, with a transmission assembly provided at one end of the second rotating rod.

[0007] Preferably, the transmission assembly includes a first gear, a second gear meshing with the bottom of the first gear, and a third rotating rod fixed to one end of the second gear.

[0008] Preferably, the end of the third rotating rod away from the second gear extends through the bearing into the hopper, and the bearing is installed on the side of the hopper.

[0009] Preferably, the third rotating rod is equipped with eccentric blocks on both sides of the outer side of the hopper, and a filter screen is attached to the top of the eccentric blocks.

[0010] Preferably, the filter screen body has movable blocks fixed at both ends, and the movable blocks are slidably connected to the grooves opened at both ends of the inner wall of the hopper.

[0011] Preferably, a circular groove is provided at one end of the first rotating rod located inside the feeding frame, and one end of an electric heating tube extends into the circular groove, while the other end of the electric heating tube is fixed to the inner wall of the feeding frame.

[0012] Preferably, the front surface of the hopper is provided with an opening, the position of which corresponds to the position of the filter screen body, and a cover plate is installed on the outside of the opening.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model combines a dual-shaft motor, crushing blades, and a transmission assembly. Not only can the dual-shaft motor drive multiple crushing blades located within the feed frame to rotate, directly crushing the material during the feeding process and avoiding feed inlet blockage, but during the crushing process, the dual-shaft motor, through the transmission assembly, also simultaneously drives multiple eccentric blocks to rotate. These eccentric blocks then move the filter screen located in the hopper up and down, directly filtering the crushed material within the hopper. This integrated crushing and filtering mechanism solves the technical problem of traditional crushers where the feeding assembly uses crushing blades at the feed inlet to crush the material, but after crushing, an additional filtering structure is needed to filter the crushed material, and this internal filtering structure occupies internal storage space.

[0015] 2. This utility model combines a first rotating rod, a circular groove, and an electric heating tube. Since the electric heating tube extends into the circular groove on the side of the first rotating rod, when the first rotating rod rotates and drives the multiple crushing blades mounted on it to rotate together, the heat generated inside the electric heating tube in the first rotating rod can be smoothly conducted to the surface of each crushing blade through the first rotating rod. Thus, while the crushing operation is in progress, the crushing blades can directly heat and dry the material, effectively improving the heating and drying effect of the material.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A feed assembly for a crusher, see [link to example]. Figures 1 to 3The system includes a feeding frame 1, with a hopper 101 connected to the bottom of the feeding frame 1. A dual-shaft motor 2 is mounted on the side of the feeding frame 1. One end of the dual-shaft motor 2 is connected to a first rotating rod 205, which extends into the feeding frame 1. Multiple crushing blades 206 are mounted on the outside of the end of the first rotating rod 205 located inside the feeding frame 1. The other end of the dual-shaft motor 2 is connected to a second rotating rod 201, with a transmission assembly at one end. The feeding assembly is first connected to the top of the crusher. After connection, when material needs to be crushed, the dual-shaft motor 2 is started. The dual-shaft motor 2 drives the first rotating rod 205 and the second rotating rod 201. The first rotating rod 205 drives the multiple crushing blades 206 located inside the feeding frame 1 to rotate, thus crushing the material entering the feeding frame 1 using the multiple crushing blades 206. During the process, the second rotating rod 201 drives the first gear 202 to rotate, the first gear 202 drives the second gear 203 to rotate, the second gear 203 drives the third rotating rod 204 to rotate, and the third rotating rod 204 drives multiple eccentric blocks 208 to rotate. Thus, the multiple eccentric blocks 208 continuously lift the filter screen 211 to filter the material after it has been crushed on the surface of the filter screen 211. After filtration, the cover plate 102 on the surface of the hopper 101 can be opened to remove the material from the surface of the filter screen 211. This solves the technical problem that in traditional crushers, the feeding assembly uses a crushing blade to crush the material at the feeding port, but after the material is crushed, an additional filtration structure is needed to filter the crushed material. Setting up a filtration structure inside the crusher will occupy the internal storage space of the crusher.

[0022] For details, see Figure 1 The transmission assembly includes a first gear 202, a second gear 203 meshing at the bottom of the first gear 202, and a third rotating rod 204 fixed at one end of the second gear 203.

[0023] Further, see Figure 2 The end of the third rotating rod 204 away from the second gear 203 passes through the bearing 207 and extends into the hopper 101. The bearing 207 is installed on the side of the hopper 101.

[0024] It is worth noting that, see Figure 2 The third rotating rod 204 is located on both sides of the outer side of the hopper 101, and eccentric blocks 208 are installed. The top of the eccentric blocks 208 is attached to the filter screen body 211.

[0025] It is worth noting that, see Figure 2 The filter screen body 211 has movable blocks 210 fixed at both the front and rear ends. The movable blocks 210 are slidably connected to the sliding grooves 209 opened at both the front and rear ends of the inner wall of the hopper 101.

[0026] It is worth mentioning that, see Figure 3 The first rotating rod 205 has a circular groove 3 at one end inside the feeding frame 1. One end of an electric heating tube 301 extends into the circular groove 3, and the other end of the electric heating tube 301 is fixed to the inner wall of the feeding frame 1. The electric heating tube 301 extends into the circular groove 3 pre-cut on the side of the first rotating rod 205. When the equipment is started, the electric heating tube 301 begins to generate heat, and the heat generated quickly accumulates inside the first rotating rod 205. The first rotating rod 205 can act as a heat transfer medium to conduct the heat generated by the electric heating tube 301. At the same time, the first rotating rod 205 begins to rotate under the power drive, and the multiple crushing blades 206 installed on its surface also rotate synchronously. During the rotation process, the first rotating rod 205 continuously crushes the internal components of the electric heating tube. The heat generated by 301 is conducted to the surface of each crushing blade 206, causing the temperature of the crushing blade 206 to gradually rise. At this time, the material is fed into the equipment. Under the high-speed rotation of the crushing blade 206, the material is subjected to strong shearing, impact and friction forces, thereby achieving the crushing effect. At the same time, the heated crushing blade 206 is in direct contact with the material, transferring heat to the material and performing heating and drying treatment. By using multiple rotating crushing blades 206 to heat the material from different angles and positions, the contact area and contact opportunities between the material and the heat source are greatly increased, allowing the material to be heated more quickly and evenly, effectively improving the heating and drying effect of the material, shortening the drying time, and improving the overall production efficiency.

[0027] It is worth emphasizing that, see Figure 1 The front surface of the hopper 101 is provided with an opening, the position of which corresponds to the position of the filter screen body 211, and a cover plate 102 is installed on the outside of the opening.

[0028] When using a crusher feeding assembly, first connect the feeding assembly to the top of the crusher. After connection, when material needs to be crushed, start the dual-shaft motor 2. The dual-shaft motor 2 will drive the first rotating rod 205 and the second rotating rod 201. The first rotating rod 205 will drive multiple crushing blades 206 located in the feeding frame 1 to rotate, using the multiple crushing blades 206 to crush the material entering the feeding frame 1. During the crushing process, the second rotating rod 201 will drive the first gear 202 to rotate. The first gear 202 will... The second gear 203 rotates, which in turn drives the third rotating rod 204 to rotate. The third rotating rod 204 then drives multiple eccentric blocks 208 to rotate, thereby continuously lifting the filter screen 211 using the multiple eccentric blocks 208 to filter the material that has been crushed on the surface of the filter screen 211. After filtration, the cover plate 102 on the surface of the hopper 101 can be opened to remove the material from the surface of the filter screen 211. When the equipment is started, the heating element 301 is energized and heats up, and the heat generated is rapidly distributed to the first rotating rod 204. The first rotating rod 205 accumulates heat inside, acting as a heat transfer medium to conduct the heat generated by the heating element 301. Simultaneously, driven by a power source, the first rotating rod 205 begins to rotate, and multiple crushing blades 206 mounted on its surface rotate synchronously. During rotation, the first rotating rod 205 continuously conducts the heat generated by the heating element 301 to the surface of each crushing blade 206, causing the temperature of the crushing blades 206 to gradually rise. At this point, the material is fed into the equipment. Under the high-speed rotation of the crushing blades 206, the material is subjected to strong shearing, impact, and frictional forces, thus achieving a crushing effect. Simultaneously, the heated crushing blades 206 directly contact the material, transferring heat to it for heating and drying. By using multiple rotating crushing blades 206 to comprehensively heat the material from different angles and positions, the contact area and opportunities between the material and the heat source are greatly increased, allowing the material to be heated more quickly and evenly, effectively improving the heating and drying effect, shortening the drying time, and increasing overall production efficiency.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
