[0022] See also Figure 1-4 , a raw material screening machine for foam concrete processing, comprising a screening box 1, and a screening and breaking mechanism 2 is arranged above the screening box 1;

[0023] The screening and breaking mechanism 2 includes a conveying frame 201, and a stepper motor 202 is arranged on the outer side of the conveying frame 201. The output end of the power of the stepper motor 202 passes through the conveying frame 201 and is fixedly installed with a rotating rod 203. A protective box 5 is fixedly installed on the bottom surface of the stepper motor 202. The back side of the protective box 5 is fixedly connected to the front side of the conveying frame 201. The stepper motor 202 can be protected by the protective box 5, thereby preventing external force from causing damage to the stepper motor 202, thereby increasing the protection of the device.

[0024] A spiral conveying blade 204 is fixedly installed on the outer surface of the rotating rod 203, and a screening plate 205 is slidably connected to the inner wall of the screening box 1. Four force springs 206 are fixedly installed on the front and back sides of the screening plate 205. A bearing 6 is fixedly installed on the end of the rotating rod 203 away from the stepper motor 202, and the back side of the bearing 6 is fixedly connected to the inner wall of the conveying frame 201. The rotating rod 203 can be supported by the bearing 6 to prevent the rotating rod 203 from falling, thereby increasing the stability of the rotating rod 203.

[0025] One end of each force spring 206 away from the screening plate 205 is fixedly connected to the inner wall of the screening box 1, a feed funnel 207 is fixedly installed on the bottom surface of the screening plate 205, and a vibration motor 208 is fixedly installed on the outer surface of the feed funnel 207. The inner wall of the screening box 1 is slidably connected to a collecting rack 209, and the upper surface of the conveying rack 201 is fixedly connected to a feed funnel 3, and a handle 4 is fixedly installed on the left side of the collecting rack 209. The feed funnel 3 is used to facilitate the placement of processed raw materials into the conveying rack 201, and the handle 4 can pull the collecting rack 209 outward, thereby facilitating the collection of the screened raw materials.

[0026] Four supporting legs 7 are fixedly installed on the bottom surface of the screening box 1, and a grounding plate 8 is fixedly installed on the bottom end of each supporting leg 7. The screening box 1 can be supported by the supporting legs 7, and the grounding plate 8 can increase the friction between the supporting legs 7 and the ground, thereby increasing the stability of the device.

[0027] A scraper 9 is slidably connected to the inner wall of the screening box 1, and a U-shaped frame 10 is fixedly installed on the left side of the scraper 9. The bottom surfaces of the scraper 9 and the U-shaped frame 10 are in contact with the upper surface of the screening plate 205. The scraper 9 can be driven to move by pulling the U-shaped frame 10, so that the scraper 9 can scrape out the impurities on the screening plate 205, thereby facilitating personnel to centrally process the impurities and increasing the convenience of the device.

[0028] The inner wall of the screening box 1 is movably hinged with a switch door 11, an L-shaped frame 12 is fixedly installed on the left side of the switch door 11, and a lock buckle 13 is fixedly installed on the left side of the screening box 1. The inner wall of the lock buckle 13 contacts the outer surface of the L-shaped frame 12. The screening box 1 can be closed during screening by the switch door 11, and the lock buckle 13 can prevent the switch door 11 from opening automatically, thereby increasing the practicability of the device.

[0029] The working principle of the utility model is as follows: when in use, firstly, the stepper motor 202 and the vibration motor 208 are powered on. When the foam concrete processing raw materials need to be screened, the raw materials are manually put into the conveying frame 201 through the feeding funnel 3. The power provided by the stepper motor 202 can drive the rotating rod 203 to rotate, thereby driving the spiral conveying blade 204 to rotate, so that the spiral conveying blade 204 can not only break up the agglomerated raw materials, but also evenly convey the raw materials, so that the raw materials can be evenly scattered on the screening plate 205. The bearing 6 can support the rotating rod 203 to prevent the rotating rod 203 from falling. The power provided by the vibration motor 208 can drive the feeding funnel 207 to shake, thereby driving the screening plate 205 to shake. The elastic force provided by the force spring 206 can limit the screening plate 205, so that the screening plate 205 can screen out impurities in the raw materials, and at the same time, it can prevent a large amount of raw materials from entering and causing the screening plate 205 to be blocked and affect the screening efficiency. The collecting rack 209 can collect the screened raw materials in a centralized manner, and the handle 4 can pull the collecting rack 209 outward. The switch door 11 can close the screening box 1 during screening, and the lock 13 can prevent the switch door 11 from opening automatically. When it is necessary to process the screened impurities, the switch door 11 is manually opened, and the scraper 9 can be driven to move by pulling the U-shaped frame 10, so that the scraper 9 can scrape the impurities on the screening plate 205 outward, thereby facilitating personnel to centrally process the impurities, making the raw material screening machine for foam concrete processing more practical.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
