The first feed ramp 4 installed on the top of the support platform 2 can be rotated by the rotating shaft 3, and the front and bottom of the first feed ramp 4 and the second feed counterweight plate 5 are supported by the support box 10. The hydraulic rod 9 can control the support box 10 to move up and down, thereby controlling the rotation of the first feed ramp 4 and the second feed counterweight plate 5. A material storage box 8 is arranged above the first feed ramp 4, and the material storage box 8 can be installed above the first feed ramp 4 through a bracket to store metal parts waiting for transportation and processing. The discharge chute opened at the lower end of the material storage box 8 is an oblique mouth, and its inclination angle is consistent with the slope angle of the surface of the first feed ramp 4 when it is laid flat. The metal parts can be blocked and stored inside the material storage box 8. When the support box 10 moves downward, the front ends of the first feed ramp 4 and the second feed counterweight plate 5 will rotate downward under the action of gravity. At this time, the metal parts located in the material storage box 8 will fall to the surface of the first feed ramp 4, and gradually slide to the front end under the rotation of the first feed ramp 4, and finally fall into the inside of the support box 10.

[0030] When it falls into the support box 10, the height of the support box 10 has been reduced to the minimum. At this time, the front end of the support box 10 is located above the upper screening box 20, and multiple mixed metal originals of different sizes will be slid into the upper screening box 20. The upper screening box 20 is equipped with a filter screen to sort large metal parts and small metal parts.

The lower end of the material storage box 8 has an oblique discharge port 15 formed therein. The oblique discharge port 15 formed at the lower end of the material storage box 8 can be used to discharge metal parts.

[0032] Reference Figure 1-3 The rear end of the first feed inclined plate 4 is fixedly connected with a rear baffle 6, and the rear end of the rear baffle 6 is fixedly connected with a knock plate 13. When the first feed inclined plate 4 is rotated, the parts in the material box 8 can be discharged, and the rear baffle 6 and the knock plate 13 can block the rear end of the first feed inclined plate 4 to prevent the parts from sliding to the rear end of the first feed inclined plate 4 and affecting the feeding.

The top side ends of the first feeding inclined plate 4 and the second feeding counterweight plate 5 are both installed with side baffles 7, and the side baffles 7 are sleeved on the outer end of the material placing box 8. During the rotation of the first feeding inclined plate 4 and the second feeding counterweight plate 5, the metal parts being fed can be protected to prevent the parts from sliding off the side ends of the first feeding inclined plate 4 and the second feeding counterweight plate 5 in advance when rolling.

The bottom of the lower material transport platform 16 is supported by the support frame 12, and the upper material transport platform 18 is installed above the lower material transport platform 16 through the support rod 17 on the surface of the lower material transport platform 16. The lower screening box 19 installed at the rear end of the lower material transport platform 16 is used to transport the smaller parts that have been screened, and the mesh 21 in the upper screening box 20 is used to store larger metal parts. When the metal parts fall into the upper screening box 20, metal parts of different size standards can be sorted.

[0036] Reference Figure 4 and Figure 5The push plate 30 is slidably connected inside the push trough 22, the rear end of the push plate 30 is fixedly connected to the electric telescopic rod 29, the bottom of the electric telescopic rod 29 is fixedly connected to the fixing frame 28, and the front end of the fixing frame 28 is fixedly connected to the upper screening box 20. The electric telescopic rod 29 can be installed on the rear end of the upper screening box 20 through the fixing frame 28. Starting the electric telescopic rod 29 can drive the push plate 30 in the push trough 22 to move forward and backward, thereby pushing the large metal parts on the surface of the sieve 21 for loading.

[0037] Reference Figure 4 The upper material transport platform 18 is internally connected with a plurality of material transport rollers 23 for rotation, a motor seat 24 is fixedly installed at the side end of the upper material transport platform 18, and a discharge plate 25 is fixedly connected to the front end bottom of the upper material transport platform 18. Starting the motor group in the motor seat 24 can drive the material transport rollers 23 in the upper material transport platform 18 to rotate, and the material transport rollers 23 can be used to transport large metal parts pushed by the push plate 30 when rotating, and the discharge plate 25 installed at the front end of the upper material transport platform 18 can discharge the metal parts transported and loaded.

[0038] Reference Figure 4 The lower conveying platform 16 is rotatably connected with a conveying roller 27, and a conveying belt 26 is sleeved on the surface of the conveying roller 27. The conveying belt 26 installed inside the lower conveying platform 16 is used to transport small metal parts. After the small metal parts fall into the lower screening box 19, they can be loaded and transported through the conveying belt 26.

The motor 35 is installed on the surface of the base 1, and when the motor 35 is started, the motor shaft 34 can be driven to rotate, and then the belt 32 and the first transmission wheel 31 are driven to rotate through the second transmission wheel 33 at the top of the motor shaft 34, and finally the transmission roller 27 and the transmission belt 26 are driven to rotate.

[0040] Working principle:

[0041] Before use, metal parts of different sizes waiting to be processed can be stored inside the material storage box 8, and then the hydraulic rod 9 is started to control the support box 10 to move slowly downward. During the downward movement of the support box 10, the lower end of the second feeding counterweight plate 5 will be driven by gravity to drive the first feeding inclined plate 4 and the second feeding counterweight plate 5 to rotate downward. When the first feeding inclined plate 4 rotates, the metal parts in the material storage box 8 can fall to the surface of the first feeding inclined plate 4 through the inclined discharge port 15, and be blocked by the side baffle 7 at the side end of the first feeding inclined plate 4 and the rear baffle 6 and knock plate 13 at the rear end to prevent the parts from sliding in other directions. When the support box 10 moves downward to the lowest height, the surface inclination angle of the first feeding inclined plate 4 will be smaller than the horizontal plane, and the metal parts on the surface of the first feeding inclined plate 4 will fall to the feeding table 11 in the support box 10 through the second feeding counterweight plate 5, and then fall to the surface of the leakage net 21 through the feeding table 11. Large-sized metal parts will flow to the surface of the mesh 21 under the screening of the mesh 21, and a few large cylindrical parts can be directly transported by rolling to the surface of the conveying roller 23. The remaining large parts can be pushed to the conveying roller 23 for loading by starting the electric telescopic rod 29 and using the push plate 30 that moves forward and backward. Small metal parts can pass through the surface of the mesh 21 and fall into the lower screening box 19. At the mesh 21, a vibrator can be added to vibrate the mesh 21 according to the screening requirements to improve the screening efficiency. Small metal parts that fall into the lower screening box 19 can be directly transported and loaded through the conveyor belt 26. During the loading process, the hydraulic rod 9 can be controlled again to drive the support box 10 to move upward. When the support box 10 moves upward, the second feeding counterweight plate 5 and the first feeding inclined plate 4 can be pushed to rotate upward, and the first feeding inclined plate 4 can be re-attached to the lower end of the material storage box 8, and the loading process is stopped, waiting for the next loading process. The device can control the feeding device to load materials in batches, can screen metal parts of different sizes mixed together, and then transport them separately, and then send them to subsequent processing devices for production work, thereby improving work efficiency.
