DETAILED DESCRIPTION
[0019] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.
[0020] Embodiment: A grading and screening device for milk powder processing, such as Figure 1 and Figure 2 As shown, it includes a base 1, a box body 2, a vibration motor 21, a screen 3, a collection plate 31, a collection frame 4, a top cover 6, a guide rail 61, an anti-skid pad 9, a shock-absorbing component and a blocking component. The bottom of the base 1 is provided with an anti-skid pad 9, and a box body 2 with an open top is provided above the base 1. Guide rails 61 are symmetrically installed on both sides of the top opening of the box body 2. A top cover 6 for blocking the top opening of the box body 2 is slidably arranged on the guide rails 61. A shock-absorbing component is arranged between the base 1 and the box body 2. No less than two layers of screens 3 are evenly spaced longitudinally inside the box body 2. The screens 3 are installed on the inner wall of the box body 2 in an inclined manner with the front lower and the rear higher, and the mesh diameter of the upper screen 3 is larger than the mesh diameter of the lower screen 3. A vibration motor 21 is installed at the bottom of the box body 2 to improve the efficiency of milk powder screening. A collecting plate 31 is also arranged inside the box body 2. The collecting plate 31 is arranged just below the lowest screen 3. The collecting plate 31 is also tilted and installed on the inner wall of the box body 2 with a low front and a high back. A collecting frame 4 is movably arranged on the box body 2. Three 7-shaped through grooves 20 are opened in the inner cavity of the box body 2. The collecting frame 4 is arranged below the 7-shaped through grooves 20. The 7-shaped through grooves 20 are connected with the corresponding screen 3 or the collecting plate 31. The milk powder on the screen 3 or the collecting plate 31 is introduced into the collecting frame 4 corresponding to the screen 3 or the collecting plate 31 through the corresponding 7-shaped through grooves 20. A blocking component for blocking the 7-shaped through grooves 20 is movably arranged on the box body 2.
[0021] like Figure 2 and Figure 3As shown, the blocking assembly includes a connecting frame 5, a baffle 51 and an N-shaped handle 52. The connecting frame 5 is slidably arranged in the inner cavity of the box body 2. The baffle 51 is longitudinally and parallelly installed on the side of the connecting frame 5 facing the screen 3 or the collecting plate 31. The baffle 51 is adapted to the 7-shaped through groove 20, and the baffle 51 is used to block the 7-shaped through groove 20. An N-shaped handle 52 is installed on the side of the connecting frame 5 facing away from the screen 3 or the collecting plate 31. The N-shaped handle 52 is provided with a first magnet 531 on the two side walls near the connecting frame 5, and a second magnet 532 matching the first magnet 531 is provided on the outer wall of the box body 2. After the N-shaped handle 52 moves toward the outside of the box body 2, when the first magnet 531 and the second magnet 532 are facing each other, the first magnet 531 and the second magnet 532 are magnetically matched, thereby releasing the blocking effect of the baffle 51 on the 7-shaped through groove 20, so that the milk powder can be introduced into the corresponding collection frame 4 through the 7-shaped through groove 20.
[0022] like Figure 1 and Figure 4 As shown, the shock absorbing assembly includes a shock absorbing spring 7, a damper 71 and a limit plate 72.

[0023] When in use, the connecting frame 5 is pushed toward the rear of the box body 2 through the N-shaped handle 52, thereby blocking the 7-shaped through groove 20 through the baffle plate 51; then, the milk powder is poured into the box body 2, and the top opening of the box body 2 is blocked through the top cover 6, and the vibration motor 21 is powered on, and the pure powdered milk powder is screened by the upper and lower layers of the screen mesh 3 and falls on the collecting plate 31, while the block granular milk powder is blocked on the screen mesh 3, thereby realizing the grading and screening operation of the milk powder; then, the N-shaped handle 52 is pulled away from the box body 2, The n-shaped handle 52 drives the connecting frame 5 to slide toward the outside of the box body 2, and the connecting frame 5 drives the baffle 51 away from the 7-shaped through groove 20, thereby releasing the blockage of the 7-shaped through groove 20. At this time, the granular or block milk powder on the screen 3 slides from the screen 3 toward the 7-shaped through groove 20, and slides into the corresponding collecting frame 4 through the 7-shaped through groove 20. The pure powdered milk powder on the collecting plate 31 also slides into the corresponding collecting frame 4 through the corresponding 7-shaped through groove 20, thereby realizing the collection function of the screened milk powder.
