Detailed Description

As shown in the attached figures 1-2, a sieving machine for separating feed finished products comprises: the conveying assembly and the vibrating screen assembly.

The transmission assembly includes: box 1, feed inlet 2, first discharge gate 3, second discharge gate 4, double-deck sieve 5, apron 11. The bottom of the box body 1 is funnel-shaped, the feed inlet 2 is arranged at the top of the middle part of one side of the box body 1, and the first discharge outlet 3 is arranged at the bottom of the other side of the box body 1 and used for discharging relatively large granulated feed; the second discharge port 4 is arranged at the funnel-shaped lowest point of the box body 1 and is used for discharging relatively small granulated feed; the double-deck sieve plate 5 is obliquely arranged in the box body 1 and can move relatively. A plurality of cover plates 11 are arranged on the upper portion of the box body 1, and cleaning of the interior of the box body 1 in a later period is facilitated.

The sieve subassembly that shakes includes: vibration supporting seat 6, vibrating motor 7, strengthening rib 8, spring 9, landing leg 10, apron 11, base 12. Vibration supporting seat 6 sets up at 1 top of box, and vibrating motor 7 sets up on the vibration supporting seat 6, strengthening rib 8 with 6 fixed connection of vibration supporting seat and welding 1 outside the box 1 be provided with four high strength spring 9 all around, four landing legs 10 respectively with spring 9 is connected, landing leg 10 fixed mounting is on the base 12 of I shape, and the increase is to the area of contact on landing leg 10 and ground, reduces the destruction to ground, in order to improve the stability of landing leg 10, can the welding of landing leg 10 both sides has a plurality of gusset plates.

In a further embodiment, as shown in fig. 3, the upper end of the double-deck screen deck 5 is provided with the feed inlet 2, and the lower end is provided with the first discharge outlet 3. The double-deck screen plate 5 comprises an upper screen plate 51 and a lower screen plate 52 which have the same structure, the screen holes 53 on the upper screen plate 51 and the lower screen plate 52 are both oval, two sides of the upper screen plate 51 are fixedly installed on a fixed frame 54, and the lower screen plate 52 can horizontally slide along the fixed frame 54. When the two screen holes 53 are completely overlapped, the aperture of the screen hole 53 is the largest, and the screen holes 53 are partially overlapped with the movement of the lower screen plate 52, and the aperture of the screen hole 53 is gradually reduced.

Specifically, as shown in fig. 4, a limiting member 55 is disposed at the lower portion of the fixing frame 54, and a plurality of limiting grooves 56 are disposed at one side of the lower screen plate 52 for fixing and limiting. The limiting member 55 is a buckle which is fixedly mounted on the fixing frame 54 through a torsion spring 57 and has a cross-sectional shape of "ㄣ". When the buckle is pressed down manually, the action force of the torsion spring 57 is overcome, the buckle is separated from the limiting groove 56, and the lower sieve plate 52 can slide smoothly; when moving the sieve to the assigned position after, because torsional spring 57 holds up power, the buckle can rotate along torsional spring 57, has the trend that keeps buckle one end to spacing recess 56 telemechanical, when the recess was located buckle department just, the buckle was fixed in on the spacing recess 56, reached fixed, spacing effect.

In a further embodiment, the double deck screen deck 5 is inclined at an angle

The following ranges are satisfied:

(ii) a Wherein mu is the dynamic friction coefficient between the double-layer sieve plate 5 and the material to be processed. When the inclination angle is too large, the retention time of the materials on the sieve plate is too short, and the screening effect cannot be achieved. If the inclination angle is too small, the material will jump up and down in the original position of the sieve plate due to the lack of component force of the downward movement of the phase, and the screening effect cannot be achieved. When the inclination angle is tested to be in the range, the effect is better.

In order to facilitate understanding of the technical scheme of the sieving machine for separating the finished feed products, the working principle of the sieving machine is briefly explained: pouring materials (finished feed products or raw materials to be screened) into a double-layer sieve plate 5 in a box body 1 from a feeding hole 2 at a certain flow rate through a manual conveying belt, wherein the materials are in a static state because the weight of the materials is smaller than the maximum static friction force, the box body 1 and the double-layer sieve plate 5 are driven to vibrate after a vibration motor 7 is started, the materials can bounce on the sieve plate in a small amplitude, and the materials gradually move downwards along the double-layer sieve plate 5 due to the action of gravity, and meanwhile, the materials with smaller particles fall into a second discharging hole 4 from the double-layer sieve plate 5 for discharging; the material with larger particles finally slides to the bottom of the double-layer sieve plate 5, and the screening process is finished by discharging from the first discharging port 3. In addition, when the diameter of the screen hole 53 needs to be changed, the size of the screen hole 53 can be changed only by sliding the lower screen plate 52.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations.
