[0026] Example:

[0027] The present application embodiment discloses a fully automatic weight sorting machine. Figure 1 , Figure 2 and Figure 3, including two connecting plates 1, a conveyor belt 18 installed between the two connecting plates 1, a vertical plate 2 fixedly connected to the bottom end surface of the connecting plate 1, a U-shaped frame 9 fixedly connected to the right end surface of the connecting plate 1, an impurity removal component 8 arranged on the inner side of the U-shaped frame 9, a blanking hole opened on the inner bottom wall of the U-shaped frame 9, a support plate 3 fixedly connected to the bottom end surface of the U-shaped frame 9 and a guide plate 10 fixedly connected to the lower right end of the U-shaped frame 9, the length and width of the blanking hole are respectively smaller than the length and width of the inner cavity of the collecting box 7, a transfer box is arranged on the bottom side of the right end of the guide plate 10, a control cabinet is installed on the surface of the connecting plate 1 close to the back side of the conveyor belt 18, the impurity removal component 8 belongs to the prior art, and its structure and working principle are all referred to a fully automatic weight sorting machine with a disclosure (announcement) number of CN217491730U, which will not be described in detail herein, a sliding hole 11 is opened on the support plate 3, and a bottom plate 14 is slidably connected to the lower inner side of the sliding hole 11;

[0028] Three rectangular plates 6 are fixedly connected to the top of the bottom plate 14, and a collection box 7 is arranged between two adjacent rectangular plates 6. A limit assembly is arranged on the outer side of the bottom plate 14, and an electric push rod 4 is arranged on the outer side of the limit assembly. After the inside of the collection box 7 far away from the fixed plate 5 is full, the electric push rod 4 is controlled to work and extend to drive the three rectangular plates 6 and the bottom plate 14 to move. When the inner surface of the fixed plate 5 abuts against the surface of the support plate 3, the electric push rod 4 stops working. At this time, the collection box 7 close to the fixed plate 5 moves to the bottom of the drop hole, and the collection box 7 far away from the fixed plate 5 moves to the outside of the support plate 3. During the movement of the bottom plate 14, the collection box 7 is moved to the bottom of the drop hole. The impurities falling from the material hole fall into the two collecting boxes 7 until one collecting box 7 moves to the outside of the support plate 3 and the other collecting box 7 moves between the two support plates 3. Then the impurities fall into one collecting box 7. Among them, the impurities falling on the top of the two collecting boxes 7 and the top of the middle rectangular plate 6 fall into the collecting box 7 due to the obstruction of the support plate 3 during the movement, so that the impurities filled in the collecting box 7 can be cleaned without stopping the machine. The output end of the electric push rod 4 is fixedly connected to the fixed plate 5, and the inner surface of the fixed plate 5 is fixedly connected to the surface of the rectangular plate 6 near the front end of the bottom plate 14.

[0029] See also Figure 2 and Figure 3The limiting assembly includes two side plates 13 and a limiting plate 12. The two side plates 13 are symmetrically fixedly connected to the top of the limiting plate 12. When the collecting box 7 is located between the two supporting plates 3, the two side plates 13 can limit the left and right sides of the collecting box 7 to improve the stability of the installation of the collecting box 7. The limiting plate 12 is arranged at the bottom of the bottom plate 14. When the bottom plate 14 moves, the limiting plate 12 can support the bottom of the bottom plate 14 to improve the stability of the bottom plate 14 when moving. The two ends of the side plates 13 are respectively fixedly connected to the inner surfaces of the two supporting plates 3, and the two ends of the limiting plate 12 are respectively fixedly connected to the inner surfaces of the two supporting plates 3. The electric push rod 4 is fixedly connected to the surface of the side plates 13.

[0030] See also Figure 3 The three rectangular plates 6 and the bottom plate 14 are integrally formed, and the distance between two adjacent rectangular plates 6 is equal, the thickness of the rectangular plate 6 is equal to the thickness of the support plate 3, and the distance between the two support plates 3 is equal to the length of the collection box 7.

[0031] See also Figure 3 The outer side of the collecting box 7 is symmetrically provided with a limiting groove 15, and a matching positioning plate 16 is arranged inside the limiting groove 15. The positioning plate 16 is fixedly connected to the rectangular plate 6. The cooperation of the positioning plate 16 and the limiting groove 15 can limit the collecting box 7. When it is necessary to clean the impurities inside the collecting box 7, after moving the collecting box 7 to the outer side of the supporting plate 3, the collecting box 7 can be removed from between the two rectangular plates 6 by only moving the collecting box 7 to the right, which is easy to operate.

[0032] See also Figure 3 A baffle 17 is fixedly connected to the back of the rectangular plate 6 near the rear end of the bottom plate 14, and the top of the baffle 17 extends to the top of the rectangular plate 6. When the bottom plate 14 is driven to move forward to utilize the collection box 7 near the baffle 17, the movement of the bottom plate 14 can drive the three rectangular plates 6 to move. When the baffle 17 moves forward and abuts against the back side of the U-shaped frame 9, the electric push rod 4 stops working, preventing the bottom plate 14 from moving forward all the time and thus disengaging from the sliding hole 11.

[0033] The implementation principle of the embodiment of the present application is as follows: when it is necessary to clean the impurities filled in the collecting box 7 away from the fixed plate 5, the electric push rod 4 is controlled to work and extend to drive the three rectangular plates 6 and the bottom plate 14 to move. When the inner surface of the fixed plate 5 abuts against the surface of the support plate 3, the electric push rod 4 is stopped. At this time, the collecting box 7 close to the fixed plate 5 moves to the bottom of the drop hole, and the collecting box 7 away from the fixed plate 5 moves to the outside of the support plate 3. During the movement of the bottom plate 14, the impurities falling through the drop hole fall into the inside of the two collecting boxes 7 until one collecting box 7 moves to the outside of the support plate 3 and the other collecting box 7 moves between the two support plates 3. The impurities only fall into the inside of one collecting box 7, wherein the impurities falling on the top of the two collecting boxes 7 and the top of the middle rectangular plate 6 fall into the inside of the collecting box 7 due to the obstruction of the support plate 3 during the movement.

[0034] After the collecting box 7 is moved to the outside of the supporting plate 3, the collecting box 7 can be removed from between the two rectangular plates 6 by simply moving the collecting box 7 to the right. The operation is convenient. When the collecting box 7 close to the fixed plate 5 is full of impurities, the electric push rod 4 is controlled to work and the collecting box 7 away from the fixed plate 5 is pushed to the bottom of the drop hole, so that the two collecting boxes 7 can be used in turn, so that the full impurities in the collecting box 7 can be cleaned without stopping the machine.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
