The building-block type setting reduces the difficulty of transportation, handling and maintenance, and only needs to be replaced targeted when a certain part is damaged, reducing the use cost.
[0020] To realize the connection and fixation between the migration section 1 and the conveying section 2, a first square block 5 is integrally formed at one end of the migration section 1 close to the conveying section 2. A first square groove 4 matching with the first square block 5 is formed on the conveying section 2. A first T-shaped groove 6 is formed on the first square block 5. A first connecting component matching with the first T-shaped groove 6 is arranged on the conveying section 2, and the first connecting component is used for connecting the migration section 1 and the conveying section 2.
[0021] Specifically, the first connecting component includes a first T-shaped block 7, a first bolt 8 and a first through groove 9. The first through groove 9 is formed inside the conveying section 2, and the first through groove 9 communicates with the first square groove 4. The first T-shaped block 7 is inserted into the first T-shaped groove 6. The first bolt 8 passes through the end of the conveying section 2 far from the migration section 1 and is in threaded cooperation with the first T-shaped block 7.
[0022] During work, insert the first T-shaped block 7 into the first T-shaped groove 6, then dock the conveying section 2 with the migration section 1. The first T-shaped block 7 is inserted into the interior of the first through groove 9. Insert the first bolt 8 into the interior of the first through groove 9 from the end of the conveying section 2 far from the migration section 1, and rotate the first bolt 8 to make it in threaded cooperation with the first T-shaped block 7, completing the connection and fixation between the migration section 1 and the conveying section 2.
[0023] A second square block 11 is integrally formed at one end of the migration section 1 close to the metering section 3. A second square groove 12 matching with the second square block 11 is formed on the metering section 3. A second T-shaped groove 13 is formed on the second square block 11. A second connecting component matching with the second T-shaped groove 13 is arranged on the metering section 3, and the second connecting component is used for connecting the migration section 1 and the metering section 3.
[0024] During specific setting, the second connection component includes a second T-shaped block 14, a second through groove 15, and a second bolt 16. The second through groove 15 is opened inside the metering section 3. The second through groove 15 communicates with the second square groove 12.
