[0024] Example 1, as shown in the attached Figure 1 To the attached Figure 3 and Figure 5 As shown, an embodiment of the present invention provides a screening device for feed production, comprising a screening box 1, a drying assembly 2 fixedly mounted on the left side of the screening box 1, a collecting assembly 3 fixedly mounted on the right side of the screening box 1, and a discharge assembly 4 fixedly mounted on the left side of the collecting assembly 3;
[0025] The screening box 1 includes a box body 11, a feed port 12 is fixedly connected to the left side of the top of the box body 11, a support foot 13 is fixedly installed on the bottom of the box body 11, a first discharge port 14 is fixedly connected to the left end of the bottom surface of the box body 11, and a second discharge port 15 is fixedly connected to the right end of the bottom surface of the box body 11. A screening filter 16 is provided in the middle of the box body 11, and support frames 17 are fixedly installed on the upper and lower sides of the right end of the inside of the box body 11. The outer surfaces of the upper and lower support frames 17 are movably connected with fixed frames 18, and the outer surfaces of the two ends of the support frames 17 are movably connected with vibration springs 19. The vibration springs 19 are located between the fixed frame 18 and the inner wall of the box body 11, and the bottom of the fixed frame 18 is fixedly connected to a vibration motor 110.
[0026] Among them, the drying box 21 is fixedly installed on the left side inside the box body 11, and the number of screening filters 16 is three. The left ends of the three screening filters 16 are respectively slidably installed on the outer surfaces of the three sliding connectors 25, and the right ends of the three screening filters 16 are rotatably installed inside the fixed frame 18. The apertures of the three screening filters 16 decrease from top to bottom, and the screening filters 16 are distributed in an inclined shape inside the box body 11. The screening filter 16 is located above the first discharge port 14.
[0027] By setting three screening screens 16, and the apertures of the three screening screens 16 decrease from top to bottom, the vibration motor 110 and the vibration spring 19 are used to control the fixed frame 18 to vibrate up and down, so that the feed on the surface of the screening screen 16 inside the fixed frame 18 is vibrated and screened. At the same time, the screened feed slides through the screening screen 16 into the inside of the discharge component 4, realizing four-level screening and improving the screening effect of the feed.
[0028] like Figure 5 As shown, the discharge assembly 4 includes a material guide trough 41 , a material receiving nozzle 42 is fixedly connected to the left side of the material guide trough 41 , and one end of the material guide trough 41 is fixedly connected to a third discharge port 43 , and the material receiving nozzle 42 is located on the lower side of the right end of the screening filter 16 .
[0029] The number of the material discharging assembly 4 is two, and the two third material discharging ports 43 are respectively located at two sides of the box body 11.
[0030] By the slope of the material guiding groove 41 and the material receiving nozzle 42, the feed on the screening filter screen 16 is screened, and then slides to the inside of the material receiving nozzle 42 through the slope of the screening filter screen 16, and is discharged from the third material discharging port 43 through the material guiding groove 41, and the two third material discharging ports 43 are respectively located at two sides of the box body 11, so that the third material discharging ports 43 at different positions discharge different specifications of the feed.
[0031] Embodiment two, as shown in the accompanying Figure 1 to the accompanying Figure 4 The embodiment of the utility model provides a kind of screening device for feed production, drying assembly 2 includes drying box 21, and drying box 21 left side upper end is fixedly installed with air supply fan 22, and drying box 21 right end is fixedly connected with three air outlet nozzles 23, and drying box 21 right side is fixedly connected with three sliding connectors 25, and air outlet nozzle 23 and sliding connector 25 are staggered distribution in the right side of drying box 21, and the inside of drying box 21 is fixedly connected with heating wire 24, and heating wire 24 is located in the left side of air outlet nozzle 23.
[0032] By the action of air supply fan 22 and heating wire 24, hot air enters the inside of box body 11, and the moisture in the feed is removed by hot air, so that the feed on screening filter screen 16 is air dried during screening, to avoid that the feed is attached to screening filter screen 16 due to excessive moisture, and affect the screening effect of screening filter screen 16.
[0033] Embodiment three, as shown in the accompanying Figure 1 to the accompanying Figure 6 The embodiment of the utility model provides a kind of screening device for feed production, and collecting assembly 3 includes fixed plate 31, and three air inlets 32 are arranged in the inside of fixed plate 31, and air inlet 32 is located at the right side of screening filter screen 16, and filter screen 34 is fixedly installed at the right end of box body 11, and dust collection box 33 is embeddedly installed at the lower end between fixed plate 31 and box body 11, and dust collection box 33 is fixedly connected with suction fan 35 at the right end of box body 11.
[0034] By the action of suction fan 35, when dust is generated during the screening of feed, the dust in the inside of box body 11 enters the cavity between fixed plate 31 and box body 11 through air inlet 32, and is blocked by filter screen 34, and falls into the inside of dust collection box 33 under the influence of gravity, so that the dust of feed is collected by dust collection box 33 for recycling, and the dust in the air is reduced, so as to affect the working environment.
[0035] The working process of the utility model is as follows:
[0036] When in use, the feed port 12 is opened, and the feed is put into the interior of the box body 11 through the feed port 12.

Under the action of the vibration motor 110, it vibrates up and down, and the screening filter 16 vibrates inside the box body 11. The feed is screened through the screening filter 16. Since the screening filter 16 is obliquely distributed inside the box body 11, the feed falls during the vibration process and falls into the inside of the two receiving nozzles 42 respectively, and is discharged from the third discharge port 43 through the guide trough 41. After screening, part of the feed is discharged through the first discharge port 14 and the second discharge port 15;
[0037] During the feed screening process, the blower 22 and the heating wire 24 work, so that the blower 22 sends air into the drying box 21, and after being heated by the heating wire 24, the air is discharged from the air outlet 23 to dry the feed on the screening filter 16, thereby reducing the moisture content of the feed during screening and preventing the feed from adhering to the surface of the screening filter 16 and affecting the screening effect of the screening filter 16;
[0038] In addition, when dust is generated during the screening process of feed, the dust inside the box body 11 passes through the air inlet 32 through the exhaust fan 35 and enters the cavity between the fixed plate 31 and the box body 11. The dust is intercepted by the filter 34 and is affected by gravity and falls into the dust box 33, so that the dust box 33 collects and recycles the feed dust.
[0039] Finally, a few points should be explained: the drawings of the embodiments disclosed in this utility model only involve structures related to the embodiments disclosed in this utility model. Other structures can refer to common designs. In the absence of conflicts, the same embodiment and different embodiments of the utility model can be combined with each other.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
