[0002] The utility model patent with patent authorization announcement number CN221493212U discloses a vibrating screen, including a screening hopper, a receiving hopper, a vibration motor and a base. The bottom of the receiving hopper is connected to the base, and the screening hopper and the receiving hopper are connected to each other up and down. A first connecting sleeve is provided at the bottom of the receiving hopper, and a flange is fixedly provided in the first connecting sleeve. The inner wall of the first connecting sleeve is fitted with the outer peripheral surface of the flange, and the vibration motor is connected to the bottom of the flange. Compared with the traditional vibrating screen that connects the flange and the receiving hopper with a connecting piece, the utility model omits structures such as the connecting piece, reduces the energy consumption of the vibration motor during transmission of the vibration force, and makes the transmission of the vibration force more direct.

[0003] However, relying solely on vibration has a poor anti-clogging effect on the filter. At the same time, large particles of raw materials after screening by the device remain on the filter, making it inconvenient to clean. Summary of the Invention

[0004] The purpose of the utility model is to provide a vibrating raw material screening device, which solves the problem that the existing vibrating raw material screen relies only on vibration and has a poor anti-clogging effect on the filter screen, and large particles of raw materials after screening by the device remain on the filter screen, which is inconvenient to clean.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a vibrating raw material screening device, including a guide hopper, a support ring is installed inside the guide hopper through a bearing, a corrugated sleeve is bonded to the upper end of the support ring, a filter screen is fixedly connected to the lower interior of the corrugated sleeve, the upper end of the guide hopper is fixedly connected to a bracket, a scratching mechanism is provided on the bracket, the lower end of the guide hopper is fixedly connected to a support cylinder, the inside of the guide hopper is fixedly connected to a support plate, a motor is fixedly installed in the middle of the lower end of the support plate, the rotating shaft of the motor passes through the support plate and is rotatably connected to the support plate, the upper end of the rotating shaft of the motor is welded with a square rod, and the lower end of the filter screen is welded with a protrusion.

[0006] The principle of the utility model is as follows: when in use, the raw materials are poured into the corrugated sleeve, the motor is started, the motor drives the square rod to rotate, the square rod drives the square cylinder to rotate, the square cylinder drives the filter screen to rotate, so that the protrusion rotates and collides with the baffle, thereby causing the filter screen to vibrate, and the motor drives the square rod to rotate, so that the protrusion and the baffle collide, causing the filter screen to vibrate, thereby preventing the filter screen from being blocked, and during the rotation of the filter screen, the scraper rubs against the filter screen and the surface of the filter screen, further preventing the filter screen from being blocked and ensuring the filtering efficiency of the filter screen, after the device is shut down, the sliding pin is manually moved up, the sliding pin drives the slide plate to move up, and the slide plate drives the pressure rod to move up, thereby causing the scraper to move up and separate from the filter screen, so that the filter screen can be taken out from the guide hopper, making it easy to take out the large particles screened out of the filter screen,

[0007] The beneficial effect of the utility model is that the spring acts on the slide plate, so that the slide plate drives the scraper to be pressed against the filter screen through the pressure rod. When the filter screen rotates, the scraper scratches the filter screen and the upper surface of the filter screen, further preventing the filter screen from being blocked and ensuring the filtering efficiency of the filter screen.

[0008] The motor drives the square rod to rotate, causing the filter to rotate, and then the bumps and baffles collide, causing the filter to vibrate and prevent the filter from being blocked. At the same time, the filter can be taken out from the guide hopper, making it easy to take out the large particles screened out of the filter.

[0009] Furthermore, a guide trough is fixedly connected to the interior of the support cylinder, and the guide trough is located below the guide hopper. The sieved raw materials are collected by setting the guide trough.

[0010] Furthermore, a square tube is slidably connected to the outer side of the square rod, and the square tube is fixedly connected to the filter screen. By arranging the square tube, the square rod and the filter screen are connected.

[0011] Furthermore, a baffle is fixedly connected to the interior of the guide hopper, and the baffle contacts the protrusion. By arranging the baffle and the protrusion to cooperate, the filter screen can vibrate.

[0012] Furthermore, the scraping mechanism includes a slide, which is fixedly connected to a bracket. A slide is slidably connected to the interior of the slide, and a spring is provided inside the slide. A pressure rod is fixedly connected to the lower end of the slide, and a scraper is fixedly connected to the lower end of the pressure rod. The scraper contacts the filter. The spring acts on the slide, causing the slide to drive the scraper to press against the filter via the pressure rod. When the filter rotates, the scraper scrapes against the filter, scraping the upper surface of the filter, further preventing filter blockage and ensuring the filter's filtration efficiency.

[0013] Furthermore, one end of the spring is fixedly connected to the bracket, and the other end of the spring is fixedly connected to the slide. By arranging the spring, the slide is pressed downward.

[0014] Furthermore, a sliding pin is fixedly connected to the edge of the slide, and the sliding pin is slidably connected to the slide cylinder. By arranging the sliding pin, the movement of the slide is guided. BRIEF DESCRIPTION OF THE DRAWINGS
