[0022] See also Figure 1-5A screw conveyor for quantitative feeding includes a conveyor body 1. The conveyor body 1 is a screw conveyor for conveying materials. A feeding pipe 2 is provided at the feeding port of the conveyor body 1. A conveying box 3 is provided on the top of the conveyor body 1. A moving plate 5 is provided inside the conveying box 3 through a moving frame 4. A discharge pipe 6 is provided inside the moving plate 5. A sealing cover 7 is provided at the bottom of the discharge pipe 6. A discharge pipe 8 is provided on the top of the moving plate 5. A blocking plate 9 is provided inside the conveying box 3. Materials enter the discharge pipe 8 into the discharge pipe 6 through the discharge pipe 8. The discharge pipe 6 and the moving plate 5 are moved so that the moving plate 5 The bottom of the discharge pipe 8 is sealed. At this time, a certain amount of material is stored in the discharge pipe 6. When the discharge pipe 6 moves, the blocking plate 9 and the sealing cover 7 are separated from each other. Under the action of gravity, the material inside the discharge pipe 6 is discharged, which is convenient for quantitative feeding of the material, avoiding blockage in the screw conveyor caused by too much material, ensuring the transmission efficiency of the conveyor body 1, so that the production efficiency is not affected and the equipment will not be damaged. A feeding assembly 11 is provided on the top of the discharge pipe 8 to facilitate the transportation of materials, and a supporting assembly 14 is provided at the bottom of the conveyor body 1 to facilitate the support of the conveyor body 1;

[0023] The feeding assembly 11 includes an open bucket 1101, which is fixedly mounted on the top of the discharge pipe 8. One side of the discharge pipe 8 is fixedly connected to the top of the mobile frame 4 through a bent rod 1102. Through the open bucket 1101, it is convenient to add materials into it, so as to fix the discharge pipe 8.

[0024] An open bucket 13 is provided at the top of the feed pipe 2, and micro vibration motors 12 are provided on both sides of the feed pipe 2 to facilitate the access of materials and to vibrate the materials inside the feed pipe 2, thereby preventing material blockage;

[0025] The open bucket 13 and the feeding pipe 6 are located in the same vertical plane, which is convenient for receiving the materials dropped when the feeding pipe 6 moves. The inside of the mobile frame 4 is provided with a moving groove 1103 matching the moving plate 5, which is convenient for the moving plate 5 to play a role of limiting and guiding when moving;

[0026] One side of the sealing cover 7 is slidably connected to the top of the blocking plate 9, so that when the sealing cover 7 is rotated, it can seal the feeding pipe 6;

[0027] An electric push rod 10 is provided inside the conveying box 3, and a telescopic rod of the electric push rod 10 is fixedly connected to one side of the feeding pipe 6, so as to drive the feeding pipe 6 to move back and forth in the horizontal direction;

[0028] The support assembly 14 includes a machine base 1401, which is arranged at the bottom of the conveyor body 1. A support base 1402 is provided at the bottom of the machine base 1401. The four corners of the bottom of the support base 1402 are provided with supporting legs 1403. The surface of the support base 1402 is provided with a plurality of reinforcement plates 1404.

[0029] When in use, the conveyor body 1 is controlled to work, and then materials are added to the inside of the open bucket 1101. The materials are stored in the discharge pipe 8 and enter the inside of the discharge pipe 6 through the discharge pipe 8. At this time, the sealing cover 7 seals the bottom of the discharge pipe 6. A certain amount of materials are stored at the discharge pipe 6. Then, the extension of the telescopic rod of the electric push rod 10 is controlled to drive the movable plate 5 and the discharge pipe 6 to move synchronously. When the movable plate 5 moves, the right side of the movable plate 5 is sealed with the bottom of the discharge pipe 8. At this time, the sealing cover 7 slides on the surface of the blocking plate 9. When the sealing cover 7 is separated from the blocking plate 9, the sealing cover 7 is rotated and opened under the action of the gravity of the materials, and the materials immediately enter the feed pipe 2 and the conveyor body 1 through the open bucket 13 to transport the materials, which is convenient for quantitative feeding of materials, avoids clogging in the screw conveyor due to excessive materials, ensures the transmission efficiency of the conveyor body 1, and does not affect the production efficiency and does not cause damage to the equipment.

[0030] After the quantitative feeding is completed, the telescopic rod of the electric push rod 10 is controlled to shorten, so that the movable plate 5 is reset again, and the material in the discharge pipe 8 enters the inside of the discharge pipe 6 again. At this time, the blocking plate 9 is cooperated to make the sealing cover 7 and the discharge pipe 6 seal again. The telescopic rod of the electric push rod 10 can be repeatedly controlled to extend and retract, and the material can be quantitatively transported, which is more convenient to use.

[0031] During transportation, the two micro vibration motors 12 can be controlled to work, so as to vibrate the material inside the feed pipe 2 to prevent material blockage, and finally the material can be transported through the conveyor body 1.
