[0023] A filter screen 23 is fixedly connected to the inner wall of the filter frame 3, and the filter screen 23 extends into the feed frame 2. A handle 22 is arranged in the center of the filter screen 23, and the handle 22 can move the filter screen 23 upward. Limiting mechanisms are arranged on both sides of the top of the filter frame 3, and the filter frame 3 is movably connected to the feed frame 2 through the limiting mechanisms. Slide blocks 19 are fixedly connected to both sides of the bottom of the filter frame 3, and slide grooves 24 are arranged on both sides of the top of the feed frame 2. The slide block 19 can slide in the slide grooves 24. The filter screen 23 can filter the material poured into the feed frame 2, and there is no need to filter it through other filtering equipment in advance before putting it into the feed frame 2, which is more convenient to operate.

[0024] Limiting columns 7 are fixedly provided on both sides of the feed frame 2, and the limiting mechanism includes a pull-out rod 6, which is movably connected to the feed frame 2, a handle 16 is provided at the top of the pull-out rod 6, and a first disc 18 is movably provided in the middle of the pull-out rod 6, and a spring 17 is sleeved on the pull-out rod 6, one end of the spring 17 is fixedly connected to the bottom of the handle 16, and the other end of the spring 17 is fixedly connected to the top of the first disc 18. A second disc 20 is also fixedly provided on the pull-out rod 6, and the second disc 20 is provided below the filter frame 3. When installing the filter frame 3, align the slider 19 at the bottom of the filter frame 3 with the slide groove 24 on the feed frame 2, push the filter frame 3 inward, and pull the pull-out rod 6 upward at the same time, continue to push the filter frame 3 inward, until the slider 19 abuts against the bottom of the slide groove 24, and release the pull-out rod 6.

[0025] The bottom end of the pull rod 6 is bent, and a limiting groove 21 is provided at the bottom of the limiting column 7. One end of the pull rod 6 that is bent can be against the limiting column 7 and extend into the limiting groove 21. The pull rod 6 is pressed downward, and the spring 17 is compressed. At the same time, the pull rod 6 is rotated so that the bent end of the pull rod 6 is facing the limiting column 7. Then the pull rod 6 is released, and the spring 17 returns to its original state due to the elastic force, thereby driving the pull rod 6 to move upward, and the bottom end of the pull rod 6 extends into the limiting groove 21. At this time, the filter frame 3 is limited at the top of the feed frame 2. The limiting column 7 and the limiting groove 21 both play a limiting role on the limiting frame. When one end of the pull rod 6 extends into the limiting groove 21, the spring 17 is in a natural state.

[0026] The transmission device includes a transmission seat 4 and a motor 5. The motor 5 is fixedly arranged on one side of the transmission seat 4. The output shaft of the motor 5 extends into the transmission seat 4. The first rotating gear 11 and the second rotating gear 13 are fixedly connected to the output shaft of the motor 5. A rotating rod 25 is rotatably connected above the first rotating gear 11 in the transmission seat 4. The first transmission gear 12 is fixedly installed on the rotating rod 25. The first transmission gear 12 is meshed with the second rotating gear 13. The rotating rod 25 passes through the transmission seat 4 to the inside of the feed frame 2. The rotating rod 25 is rotatably connected to the side wall of the feed frame 2. The other end of the rotating rod 25 is fixedly connected to a stirring blade 26. Start the motor 5, and the output shaft of the motor 5 drives the first rotating gear 11 and the second rotating gear 13 to rotate. The rotation of the second rotating gear 13 will drive the first transmission gear 12, the rotating rod 25 and the stirring blade 26 to rotate. The rotation of the stirring blade 26 can stir and mix the materials.

[0027] Two screws 15 are rotatably connected below the first rotating gear 11 in the transmission seat 4, and the second transmission gears 14 are fixedly connected to the two screws 15. The two second transmission gears 14 are meshed with the first rotating gear 11. The screw 15 passes through the transmission seat 4 and the feed frame 2. A through groove is opened on the side of the feed frame 2 away from the transmission seat 4, and the screw 15 passes through the through groove. The outer side of the through groove on the feed frame 2 is fixedly connected to the outer side of the through groove, and the end of the shell 8 is fixedly connected to the discharge port 10. The screw 15 is rotatably connected to the two side walls of the feed frame 2. The rotation of the first rotating gear 11 will drive the second transmission gear 14 and the screw 15 to rotate. The material is stirred and mixed by the stirring blades 26, and then evenly transported to the discharge port 10 through the two screws 15.

[0028] The two screws 15 rotate in opposite directions, so that the material is better stirred and mixed during the conveying process, ensuring the uniformity of the material.

[0029] The top and bottom ends of the discharge port 10 are threadedly connected with protective covers 9 to prevent foreign matter from entering the device when the device is not in use, thereby affecting the next use.

[0030] The working principle provided by the utility model is as follows: the twin-screw feeder with filtering function aligns the slider 19 at the bottom of the filter frame 3 with the slide groove 24 on the feed frame 2, pushes the filter frame 3 inward, and pulls the pull rod 6 upward at the same time, so that the bottom end of the pull rod 6 is higher than the limit column 7, and continues to push the filter frame 3 inward until the slider 19 abuts against the bottom of the slide groove 24, releases the pull rod 6, and presses the pull rod 6 downward, the spring 17 is compressed, and at the same time the pull rod 6 is rotated so that one end of the pull rod 6 is bent toward the limit column 7, and then the pull rod 6 is released, and the spring 17 is restored to its original state due to the elastic force, thereby driving the pull rod 6 to move upward, and the bottom end of the pull rod 6 extends into the limit groove 21. At this time, the filter frame 3 is limited at the top of the feed frame 2, and then the motor 5 is started, and the output shaft of the motor 5 drives the first rotating gear 11 and the second rotating gear 13 to rotate. 4 is meshed, the second rotating gear 13 is meshed with the first transmission gear 12, the rotation of the first rotating gear 11 will drive the second transmission gear 14 and the screw 15 to rotate, and the rotation of the second rotating gear 13 will drive the first transmission gear 12, the rotating rod 25 and the stirring blade 26 to rotate. At this time, the material is put into the filter screen 23, and the material after passing through the filter screen 23 is transported downward, mixed by the stirring blade 26, and then evenly transported to the discharge port 10 through the two screws 15. After the material is put in once or multiple times, the pull-out rod 6 can be pressed downward and rotated outward at the same time to make the bottom end of the pull-out rod 6 leave the limiting column 7 and the limiting groove 21, and then the pull-out rod 6 is pulled upward to make the bottom end of the pull-out rod 6 located between the top of the limiting column 7 and the bottom end of the filter frame 3, and the filter frame 3 can be taken out. Before taking out the filter frame 3, the handle 22 can be pulled upward to prevent the filter screen 23 from getting stuck during the taking-out process.
