These crushers can effectively process various solid raw materials to meet the production needs of different industries.
[0003] In the prior art, most traditional crushers do not have a screening function, and are unable to screen out relatively fine materials when crushing materials. This results in fine materials being mixed inside the materials during crushing, and crushing by extrusion may cause the fine materials to be compacted and aggregated again. The dust generated by the crusher during crushing cannot be effectively controlled, resulting in poor air quality around the crusher, affecting the physical and mental health of the staff.

[0011] 1. The self-screening multifunctional pulverizer can quickly screen and collect relatively fine materials through the setting of the dividing plate and the air blowing component, so as to avoid re-compacting the fine materials during the crushing process, thereby greatly increasing the overall crushing efficiency of the device. During the crushing process, air flow is blown into the collecting tank through the air blowing component, so that the air pressure in the collecting tank is reduced, so that the air flow in the crushing tank above the collecting tank flows into the collecting tank.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-3 The self-screening multifunctional crusher comprises a feed chute 1, a collecting chute 2 and a crushing chute 3. The lower end of the feed chute 1 is connected to the crushing chute 3, the lower end of the crushing chute 3 is connected to the collecting chute 2, a dividing plate 4 is arranged between the crushing chute 3 and the collecting chute 2, a discharge hole 5 is arranged on the dividing plate 4, slide grooves 6 are arranged on the wall surfaces on both sides of the crushing chute 3, a crushing head 7 is arranged in the slide groove 6, and the crushing head 7 is connected to the driver 9 through a telescopic rod 8. A blast assembly 10 is arranged at one end of the collecting chute 2, and the other end is connected to the collecting assembly.
[0019] The self-screening multifunctional pulverizer is mainly composed of a feed chute 1, a crushing chute 3, a dividing plate 4, a crushing head 7, a collecting chute 2, an air blast assembly 10 and a collecting assembly. The lower end of the feed chute 1 is connected to the crushing chute 3 to guide the material into the crushing chute 3. The lower end of the crushing chute 3 is connected to the collecting chute 2 to collect the crushed and screened materials. A dividing plate 4 is arranged between the crushing chute 3 and the collecting chute 2, and a discharge hole 5 is arranged on the dividing plate 4 to screen and separate the crushed materials. Slideways 6 are arranged on the wall surfaces on both sides of the crushing chute 3, and a crushing head 7 is arranged in the slideway 6. The crushing head 7 is connected to the driver 9 through a telescopic rod 8, and the driver 9 drives the crushing head 7 to rotate to crush the material. A blast assembly 10 is arranged at one end of the collecting chute 2 to generate airflow, and the other end is connected to the collecting assembly to discharge the screened materials.
[0020] The material to be crushed is placed in the feed chute 1, and the material enters the crushing chute 3 through the feed chute 1. The driver 9 drives the crushing head 7 to collide, and at the same time controls the crushing tip 701 to rotate at high speed to crush the material. The crushed material is screened on the dividing plate 4, and the material that meets the particle size requirements enters the collecting chute 2 through the discharge hole 5, and the material that does not meet the requirements continues to stay in the crushing chute 3 for further crushing. The screened material gathers in the collecting chute 2, and the airflow generated by the blast assembly 10 helps the material enter the collecting chute 2 more quickly.
[0021] The working principle of the self-screening multifunctional pulverizer is mainly based on the crushing and screening process of the material in the crushing tank 3. The crushing head 7 is driven by the driver 9 to rotate at high speed, impact, shear and rub the material, so as to crush it to the required particle size. The crushed material is screened on the dividing plate 4, and the material that meets the particle size requirements enters the collecting tank 2 through the discharge hole 5, realizing the integration of material crushing and screening. The airflow generated by the blast assembly 10 helps to speed up the screening process and improve the screening efficiency.
[0022] The self-screening multifunctional pulverizer can realize rapid pulverization and screening of materials, thereby improving production efficiency. By replacing the material dividing plate 4 of different models, the size of the discharge hole 5 can be adjusted to meet the screening requirements of materials of different particle sizes. The design of the air blowing component 10 enables the airflow to be recycled, thereby reducing energy consumption. The equipment has a high degree of automation, reduces manual operation and intervention, and reduces labor intensity.
[0023] The feed chute 1 is in a trapezoidal shape and is inverted, with a narrow end at the lower end connected to the crushing chute 3 and an open end as a feed port.
[0024] The trapezoidal design allows the material to slide into the crushing trough 3 more naturally and smoothly under the action of gravity, avoiding blockage or scattering of the material during the falling process, thereby ensuring the continuity and stability of the crushing process. The inverted trapezoidal design makes the opening end of the feed trough 1 larger, which is convenient for a large amount of material to enter, while the narrow end can effectively control the flow rate of the material entering the crushing trough 3. This design helps to avoid problems such as insufficient crushing or equipment overload caused by excessive material flow rate. Since the material has been preliminarily sorted and guided by the feed trough 1 before entering the crushing trough 3, the distribution of the material in the crushing trough 3 is more uniform, which is conducive to improving the crushing efficiency and uniformity of the crushing head 7. Reasonable material flow rate and distribution can effectively reduce the workload of the crushing head 7, reduce the energy consumption and wear of the equipment, and thus extend the service life of the equipment. The feed trough 1 can adapt to materials of different properties and particle sizes, improving the versatility and adaptability of the equipment.
[0025] The crushing end surface of the crushing head 7 is densely distributed with crushing tips 701.
[0026] The design of the crushing tip 701 enables the crushing head 7 to generate stronger impact and shear force when rotating, thereby more effectively crushing the material to the desired particle size. This design is particularly suitable for processing materials with higher hardness or higher toughness, and can significantly improve the crushing efficiency. Since the crushing tips 701 are densely distributed on the crushing end face, the crushing head 7 can act evenly on the material during the crushing process, reducing crushing dead angles and unevenness. This helps to obtain a more uniform and consistent crushing effect and improve product quality. By optimizing the shape and distribution of the crushing tips 701, the crushing head 7 can be subjected to a more uniform force when rotating, reducing unnecessary energy loss and wear. This helps to reduce the operating cost of the equipment and extend the service life of the crushing head 7.
[0027] The discharge holes 5 are evenly distributed on the dividing plate 4 . The dividing plate 4 is provided with various models, and the discharge holes 5 provided on each model of the dividing plate 4 are of different sizes.
[0028] Since the discharge holes 5 are evenly distributed, the material can be evenly screened on the dividing plate 4, ensuring the accuracy and consistency of the screening process. At the same time, the discharge holes 5 on the dividing plates 4 of different models are of different sizes, and the appropriate dividing plate 4 can be selected as needed to achieve precise control of the material particle size and meet different production needs. The evenly distributed discharge holes 5 help the material to pass quickly on the dividing plate 4, reduce blockage and accumulation, and thus improve the screening efficiency. In addition, various types of dividing plates 4 can be selected according to the properties and particle size characteristics of the material, further optimize the screening process, and improve the screening speed and effect. By setting various types of dividing plates 4, the self-screening multifunctional crusher can adapt to the screening needs of materials of different particle sizes and properties. Whether fine screening or coarse screening is required, it can be achieved by replacing the dividing plate 4, which enhances the flexibility and adaptability of the equipment. The uniform distribution of the discharge holes 5 and the modular design of the dividing plate 4 make the operation and maintenance of the equipment easier. The operator only needs to select the appropriate dividing plate 4 for replacement according to the production needs, without the need for complex adjustment or maintenance of the equipment, reducing the difficulty and cost of operation.
[0029] The air blowing assembly 10 is evenly distributed with a plurality of air blowing holes.
[0030] The blast holes are evenly distributed on the blast assembly 10, so that the generated airflow can act evenly on the collecting tank 2, avoiding the situation of concentrated or dispersed airflow. This uniform airflow distribution helps to evenly disperse and quickly screen the materials in the collecting tank 2, thereby improving the screening efficiency and effect. The airflow generated by the blast holes can form a certain airflow field in the collecting tank 2, and quickly take the smaller material particles away from the crushing tank 3 and enter the collecting tank 2. This airflow-assisted screening method significantly improves the screening speed, making the crushing and screening process more efficient. The airflow generated by the evenly distributed blast holes can effectively prevent the material from being blocked in the collecting tank 2. The action of the airflow keeps a certain gap between the material particles, reduces the possibility of material accumulation and blockage, and ensures the smooth progress of the screening process. The airflow generated by the blast assembly 10 also helps to clean up the dust and residue inside the equipment, reducing the pollution to the working environment. At the same time, the uniform airflow distribution also reduces noise and vibration, and improves the comfort of the working environment.
[0031] Working principle: First, add the material to be crushed into the lower trough 1, and the material enters the crushing trough 3 after passing through the lower trough 1. The relatively fine material is brought to the collecting trough 2 through the discharge hole 5. During the crushing process, air flow is blown into the collecting trough 2 through the blowing assembly 10, so that the air pressure in the collecting trough 2 is reduced, so that the air flow in the crushing trough 3 above the collecting trough 2 flows into the collecting trough 2. In the process of the air flow in the crushing trough 3 flowing to the collecting trough 2, the relatively fine material is entrained and enters the collecting trough 2 through the discharge hole 5, thereby achieving the purpose of rapid screening. The new fine material generated after crushing in the crushing trough 3 is brought into the collecting trough 2 through the air flow, and continuous screening is achieved.
