When the upper material is put into the box body 1, by turning on the external power switch of the motor 14, the rotating rod 15 at the output end of the motor 14 starts to rotate, and the rotation of the rotating rod 15 can drive the cam 16 fixed at the port to rotate, and the rotation of the cam 16 can push the screen frame 2 to move left and right in the box body 1, thereby accelerating the screening of the material in the screen frame 2.

[0020] The other side of the screen frame 2 is connected to the telescopic rod 22, and the other side of the telescopic rod 22 is fixedly arranged on one side of the box body 1. A spring 23 is sleeved on the outside of the telescopic rod 22. One end of the spring 23 is connected to the screen frame 2, and the other end is connected to the side wall of the box body 1. When the screen frame 2 is pushed by the cam 16, the screen frame 2 can squeeze the telescopic rod 22 on the other side. During the squeezing process of the telescopic rod 22, the spring 23 can be deformed and squeezed synchronously. When the cam 16 rotates to the other side, the spring 23 needs to return to its original state. The spring 23 can push the screen frame 2 to move to the other side, and the screen frame 2 can swing left and right in the box body 1 to speed up the screening efficiency of the material.

[0021] The box body 1 is provided with a weighing box 3 at the lower end, an electric push rod 31 is fixedly provided on the side wall of the box body 1, a push plate 32 is provided at the output end of the electric push rod 31, a pressure sensor 35 is provided at the lower end of the weighing box 3, a connecting rod 34 is provided at the upper end of the pressure sensor 35, a weighing plate 33 is provided at the upper end of the connecting rod 34, when the material is screened, it is introduced into the weighing box 3, the material falls onto the weighing plate 33, the weighing plate 33 transfers the weight to the pressure sensor 35 through the connecting rod 34, when the material reaches the preset value, the upper end is closed, The discharge port 13 is opened, and the switch of the electric push rod 31 is turned on. The electric push rod 31 can push the push plate 32 at the front end, and the push plate 32 is slidably connected to the upper end of the weighing plate 33, and the weighing plate 33 is slidably connected in the weighing box 3. The push plate 32 can push the material to move from one side of the weighing plate 33. A discharge port 36 is provided on the outside of the box body 1, and the side end of the discharge port 36 is connected to the weighing box 3. The material is discharged through the discharge port 36, and the weighed material is collected, and the material can be automatically weighed and discharged, which brings convenience to the workers' operation.

[0022] In the above scheme, a feeding port 11 is provided on the top of the box body 1 , and a screen frame 2 is provided at the lower end of the feeding port 11 , and materials to be screened and weighed are fed into the feeding port 11 .

[0023] In the above scheme, sliders 21 are provided on both sides of the screen frame 2, and the sliders 21 are slidably connected to the slide rods 17. The slide rods 17 are fixedly arranged on the side walls of the box body 1. When the screen frame 2 slides left and right in the box body 1, the sliding of the sliders 21 on the slide rods 17 can guide the shaking of the screen frame 2, so that the shaking of the screen frame 2 left and right is more stable.

[0024] In the above scheme, a partition 12 is fixedly provided on the inner wall of the box body 1, and a discharge port 13 is provided at the lower end of the partition 12. A control valve is provided on the discharge port 13. By opening the switch of the control valve through an external controller, the screened material can be introduced into the weighing box 3. When the weight of the material inside the weighing box 3 is sufficient, the control valve can be closed to prevent the material from entering the weighing box 3 again, thereby ensuring that the weight of the material required to be weighed at the weighing box 3 is constant.

[0025] Working principle:

[0026] When the weighing and screening device is working, the material to be screened and weighed is fed into the feeding port 11, and the external power switch of the motor 14 is turned on, so that the rotating rod 15 at the output end of the motor 14 starts to rotate. The rotation of the rotating rod 15 can drive the cam 16 fixed at the port to rotate, and the rotation of the cam 16 can push the screen frame 2 to move left and right in the box body 1, so as to accelerate the screening of the material in the screen frame 2. The switch of the control valve is turned on by the external controller, so that the screened material can be introduced into the weighing box 3. When the weight of the material in the weighing box 3 is sufficient, the control valve can be closed, and the switch of the electric push rod 31 is turned on at this time. The electric push rod 31 can push the push plate 32 at the front end, and the push plate 32 can push the material to move from one side of the weighing plate 33. The material is discharged through the discharge port 36, and the weighed material is collected. The material can be weighed and discharged automatically, which brings convenience to the workers' operation.
