[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.
[0022] Reference Figure 1-4 As shown, a screening device for feed processing includes a screening box 1 and a support frame 2. The support frame 2 is arranged at the bottom of the screening box 1. Vibrating screen springs 3 are fixedly connected to the four corners of the upper end of the support frame 2. The screening box 1 and the support frame 2 are connected by the vibrating screen springs 3, which can effectively reduce the direct impact of vibration on the supporting structure and improve the stability and durability of the device. At the same time, the vibrating screen spring 3 can also provide a stable vibration source, helping the material in the screening box 1 to be efficiently screened, thereby improving screening efficiency and quality. Two connecting ears 4 are fixedly connected to the front and back sides of the screening box 1. The bottom surfaces of the four connecting ears 4 are respectively fixedly connected to the top of the four vibrating screen springs 3. A dust removal component 14 is provided on the top of the screening box 1. A first screen plate 6 is fixedly connected to the upper end of the screening box 1, a second screen plate 8 is fixedly connected to the middle position of the screening box 1, and an inclined base 10 is fixedly connected to the lower end of the screening box 1. A first heating lamp 15 is fixedly installed on the left end of the top wall of the screening box 1, and a second heating lamp 16 is fixedly installed between the right wall of the screening box 1 and the first and second screen plates 6 and 8. The setting of the heating lamp helps to dry the material during the screening process, preventing the material from caking or affecting the screening effect due to moisture. Especially when processing feed raw materials containing a certain amount of moisture, the role of the heating lamp is particularly significant, which can significantly improve screening efficiency and product quality.
[0023] Furthermore, a first guide plate 7 is fixedly connected to the left side of the screening box 1 at a position corresponding to the first screen plate 6, a second guide plate 9 is fixedly connected to the right side of the screening box 1 at a position corresponding to the second screen plate 8, and a third guide plate 11 is provided at the left bottom end of the screening box 1 at a position corresponding to the inclined base 10. The double-layer screen plate design enables fine grading of materials to meet the production needs of feed with different particle size requirements. The first screen plate 6 and the second screen plate 8 are tilted relative to each other, which improves screening efficiency and accuracy while reducing clogging and wear of materials during the screening process.
[0024] Furthermore, a fixing base 12 is fixedly connected to the middle position of the bottom of the screening box 1. A vibration motor 13 for vibration is fixedly installed on the left side of the fixing base 12. The vibration motor 13, as the main power source of the screening device, can provide a stable and controllable vibration force, causing the material in the screening box 1 to continuously vibrate and tumble, thereby improving the screening efficiency and screening accuracy. At the same time, the installation position of the vibration motor 13 is reasonable, which can ensure the uniform transmission of the vibration force and reduce the vibration and noise of the equipment. The vibration motor 13 can be a YZSB series vibration source three-phase asynchronous motor.
[0025] Furthermore, the dust removal assembly 14 includes a dust removal cylinder 1402, and several support rods 1401 are fixedly connected to the left side of the bottom of the dust removal cylinder 1402. The dust removal cylinder 1402 is fixedly connected to the top surface of the screening box 1 through the support rods 1401. A feed hopper 1405 is fixedly connected to the right side of the top of the dust removal cylinder 1402, and a dividing strip 1406 is fixedly connected to the lower end of the feed hopper 1405.
[0026] Furthermore, an axial flow fan 1403 is rotatably connected to the left side of the dust removal cylinder 1402, and a servo motor 1404 is fixedly installed on the left end of the front side of the dust removal cylinder 1402. The output end of the servo motor 1404 passes through the front side wall of the dust removal cylinder 1402 and is fixedly connected to the front end of the axial flow fan 1403.
[0027] Furthermore, a guide groove 1408 is fixedly connected to the bottom of the dust removal cylinder 1402, the upper end of the guide groove 1408 is connected to the interior of the dust removal cylinder 1402, and the lower end of the guide groove 1408 is connected to the interior of the screening box 1. An blocking seat 1407 is fixedly connected to the bottom surface of the dust removal cylinder 1402 and the right side of the guide groove 1408.
[0028] Furthermore, an inspection door 5 is hingedly connected to the front side of the screening box 1. The provision of the inspection door 5 facilitates the daily maintenance and overhaul of the equipment. When it is necessary to clean the screen, replace the screen plate, or inspect the internal condition of the equipment, it is only necessary to open the inspection door 5 to perform the operation without disassembling the entire screening box 1, which greatly improves work efficiency and convenience.
[0029] Working principle: When in use, the raw material first enters the dust collector 1402 through the feed hopper 1405, and the dividing strips 1406 in the feed hopper 1405 divide the raw material into strands. During the pouring process, the output end of the servo motor 1404 drives the axial flow fan 1403 to rotate. The rotation of the axial flow fan 1403 will cause the air inside the dust collector 1402 to flow, thereby blowing out the dust or smaller impurities in the raw material, and the raw material falls onto the first screen plate 6. At this time, the vibration motor 13 drives the screening box 1 to vibrate and screen the material. The largest screening particles passing through the first screen plate 6 leak out from the first guide plate 7, the medium-sized screening particles passing through the second screen plate 8 leak out from the second guide plate 9, and the smallest particles leak out from the third guide plate 11 along the inclined base 10. The operation of the first heating lamp 15 and the second heating lamp 16 will increase the internal temperature of the screening box 1, thereby drying the raw material.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention.
