Abstract
Description
Technical Field
[0001] This utility model relates to the field of crushers, specifically a crusher with high crushing efficiency. Background Technology
[0002] A crusher is a device used to crush large solid raw materials to the required size. There are many types of crushers and their application scenarios are also different. Large crushers are mainly suitable for crushing and processing mineral materials in industries such as metallurgy, building materials, chemical industry, mining, highway construction, water conservancy and hydropower, refractory materials, and steel. Crushers for the food industry are usually smaller in size and have more complete functions.
[0003] In the food processing field, pulverizers are among the most common mechanical equipment, used to pulverize grains such as walnuts, peanuts, and soybeans for subsequent processing. For example, Chinese patent application number CN202421400625.2 describes a fragrant rice grain pulverizer, including an anti-clogging component: a motor, located on the rear side wall of the pulverizing chamber, with the motor output shaft extending through and into the interior of the pulverizing chamber; a rotating shaft, rotatably connected to the inner wall of the pulverizing chamber; a cam, fixedly connected to the outside of the rotating shaft; a spring, symmetrically arranged in the cavities on both sides of the pulverizing chamber; a support plate, located on top of the spring; a sieve plate, located on each support plate; and a brushing mechanism, located on the pulverizing chamber and the sieve plate. The aforementioned patent describes a common type of pulverizer used in food processing. However, in practical applications, this patent cannot independently perform secondary crushing of rice that does not meet the standards. Furthermore, under the action of the brushing mechanism, larger-sized rice that does not meet the screening standards will be forced through the sieve plate under the pressure of the brushing mechanism. This can easily lead to sieve plate blockage and reduced crushing efficiency. Additionally, it can cause larger-sized rice that does not meet the screening standards to enter the lower part of the pulverizer, thus reducing the quality of the crushing process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] See Figures 1-2A high-efficiency crusher includes a crushing chamber 1 and an air pressurization pump 18. An operation box 2 is fixedly installed on the shell of the crushing chamber 1. The crushing chamber 1 is connected to the feed nozzle 11 via a discharge pipe 12. A transmission wheel 3, which is connected to an external power device, is located above the crushing chamber 1. The transmission wheel 3 is connected to a power output shaft 5 via a transmission box 4. The power output shaft 5 is keyed to a drive wheel 6, which is connected to a driven wheel 7. A first crushing shaft 8 is installed below the drive wheel 6, and a second crushing shaft 9 is installed below the driven wheel 7. Multiple crushing shafts are mounted on both the first crushing shaft 8 and the second crushing shaft 9. The ends of the crushing hammer 10, the first crushing shaft 8, and the second crushing shaft 9 are respectively connected to the filter screen 14 located inside the crushing chamber 1 through a limiting end groove 15. Multiple vibrators 24 are provided on the bottom circumference of the filter screen 14. A storage chamber 21 is provided below the filter screen 14. The storage chamber 21 is connected to the feed valve 23 below. The air pressurization pump 18 is connected to the air filter 19. An air intake grille 20 is installed on the side of the air filter 19. The air pressurization pump 18 is connected to the diversion pipe 16. Multiple air nozzles 17 are provided on the diversion pipe 16. The air nozzles 17 are located below the filter screen 14.
[0020] See Figure 3 The control box 2 includes a circuit board 201 electrically connected to the air pressurization pump 18 and the vibrator 24 respectively. A display screen 202 is electrically connected to the circuit board 201. Below the display screen 202, there is a vibration control area 203 and an air injection control area 204. Below the vibration control area 203 and the air injection control area 204, there are a switch button 205, an automatic maintenance button 206 and a work indicator light 207 electrically connected to the display screen 202. This arrangement makes it convenient for users to control and adjust the working frequency, start time and other parameters of the vibrator 24 through the vibration control area 203, and to control and adjust the working time, pressurization power and other parameters of the air pressurization pump 18 through the air injection control area 204, so as to adapt to the crushing and processing of different materials.
[0021] See Figure 1 and Figure 2 The bottom of the crushing chamber 1 is provided with a support leg 22, which is welded to the crushing chamber 1. The support leg 22 is an adjustable structure, which makes it easy for this device to adapt to different terrains.
[0022] See Figure 1 The feed nozzle 11 is equipped with a breathable and waterproof cover 13 with a built-in waterproof and breathable membrane. The feed nozzle 11 and the breathable and waterproof cover 13 are connected by a snap fastener that can be detached by friction. This setting makes it convenient for large particles of material stuck on the filter screen 14 to enter the crushing chamber 1 after the high-speed air flow is ejected from the air nozzle 17. The high-speed air flow then slows down, the air pressure drops rapidly, and the air is discharged through the breathable and waterproof cover 13.
[0023] See Figure 2 Each air nozzle 17 has a built-in solenoid valve and is electrically connected to the control box 2. This configuration makes it easy to set parameters through the control box 2 to control the opening and closing of the air nozzle 17, thereby achieving controllable air jet.
[0024] See Figure 2 The filter screen 14 is fixedly connected to the limiting end groove 15, and the limiting end groove 15 is rotatably connected to the first crushing shaft 8 and the second crushing shaft 9 respectively. This setting allows the filter screen 14 to provide a limiting function for the first crushing shaft 8 and the second crushing shaft 9 through the limiting end groove 15, so that their relative positions remain unchanged when crushing materials, thereby ensuring the crushing effect.
[0025] Working Principle: When using this device, first connect it to the external power grid via the operation box 2 to supply power. Then, connect the transmission wheel 3 to the external power equipment via a transmission belt and chain. The power equipment drives the transmission wheel 3 to rotate, which in turn drives the power output shaft 5 via the transmission box 4. The power output shaft 5 drives the driving wheel 6, which in turn drives the driven wheel 7. This causes the driving wheel 6 and driven wheel 7 to rotate relative to each other, which in turn drives the crushing shaft 1 8 and crushing shaft 2 9 to rotate relative to each other. The crushing hammers 10 on the crushing shaft 1 8 and crushing shaft 2 9 crush the material fed into the crushing chamber 1 through the feed nozzle 11 and sliding into the crushing chamber 1 via the discharge pipe 12. The material is crushed and falls above the filter screen 14. Under the control of the operation box 2, the vibrator 24 drives the filter screen 14 to vibrate, so that the material falls into the storage chamber 21 for storage after being filtered by the filter screen 14. After working for a certain period of time, the operation box 2 controls the air pressurization pump 18 to operate, pressurize the air filtered by the air filter 19, and send it to the air nozzle 17 through the diverter pipe 16. The material that cannot pass through the filter screen 14 is sprayed upward and re-enters the crushing area between the first crushing shaft 8 and the second crushing shaft 9 for secondary crushing processing. At the same time, it avoids the material particles from clogging the filter screen 14. This cycle is repeated to achieve automated and efficient crushing processing.
