Example (b): a high-efficiency double-screw extruder is shown in figures 1 and 2 and comprises a rack 1 and a hopper 2 arranged on the rack 1, wherein an observation hole 16 is formed in the hopper 2 in the vertical direction, a transparent plate 17 used for sealing the observation hole 16 is fixedly arranged in the observation hole 16, the transparent plate 17 enables materials in the hopper 2 to be difficult to leak out of the observation hole 16, and meanwhile, workers can know the remaining conditions of the materials in the hopper 2 in time through the transparent plate 17; set firmly the last work or material rest 3 that the part is located 2 tops of hopper on the lateral wall of hopper 2, it is connected with storage case 5 to go up to rotate through axis of rotation 4 on the work or material rest 3, the slope has set firmly a plurality of strengthening ribs 9 between axis of rotation 4 and the storage case 5, the both ends difference fixed connection of a plurality of strengthening ribs 9 is on the periphery of axis of rotation 4 and storage case 5, the intensity of junction between axis of rotation 4 and the storage case 5 has been strengthened in the setting of strengthening rib 9, so that storage case 5 can follow axis of rotation 4 and stably rotate, the one end that hopper 2 was kept away from to storage case 5 has set firmly the part and has extended barrier plate 6 of storage case 5, storage case 5 sets up downwards.

As shown in fig. 2 and 3, a supporting plate 7 is fixedly arranged on the feeding frame 3, a part of the rotating shaft 4 extends to the upper side of the supporting plate 7, a motor 8 controlled by a control system is fixedly connected to the supporting plate 7, a driving gear 11 is fixedly arranged at the output end of the motor 8, a driven gear 10 meshed with the driving gear 11 is fixedly sleeved on the rotating shaft 4, an annular baffle plate 15 partially extending upwards out of the feeding hopper 2 is fixedly arranged on the feeding hopper 2 along the outer periphery, and two ends of the annular baffle plate 15 are respectively and fixedly connected to the feeding frame 3. Therefore, when a worker observes that the materials in the hopper 2 are insufficient through the transparent plate 17, the materials can be poured into the storage box 5, the materials can be obliquely accumulated in the storage box 5 under the blocking effect of the blocking plate 6 (refer to fig. 1), then the worker can start the motor 8 to drive the driving gear 11 to drive the driven gear 10 to rotate, the rotating shaft 4 and the storage box 5 can be driven by the driven gear 10 to rotate upwards, and the materials in the storage box 5 can fall into the hopper 2 along the storage box 5 under the influence of self gravity until the storage box 5 rotates to an obliquely upwards state relative to the hopper 2, so that the effect of quickly and labor-saving pouring the materials into the hopper 2 is achieved, and the efficiency of the feeding process is improved; the arrangement of the ring-shaped baffle 15 reduces the possibility that part of the material is impacted on the inner wall of the hopper 2 and then popped out from the hopper 2 in the feeding process, thereby enhancing the feeding stability of the storage box 5.

As shown in fig. 3, two spliced poles 13 have been set firmly along vertical direction on the terminal surface of backup pad 7 orientation axis of rotation 4, two spliced poles 13 are put on the shelf and are used for covering the protection casing 12 of establishing driving gear 11 and driven gear 10, offer the fluting 24 that is used for supplying axis of rotation 4 to pass on the protection casing 12, fluting 24 extends protection casing 12 towards the one end of backup pad 7, protection casing 12 wears to establish protection casing 12 and the mode and the backup pad 7 mutual fixed connection of threaded connection in spliced pole 13 respectively through two connecting bolt 14, driving gear 11, driven gear 10 and motor 8 are all covered and are established in protection casing 12. Therefore, the protective cover 12 has the effect of isolating the driving gear 11 and the driven gear 10 from the outside, so that the materials or other impurities ejected in the feeding process are difficult to fall into the driving gear 11, the possibility that the driving gear 11 and the driven gear 10 are blocked by foreign matters is reduced, and the feeding operation of the material storage box 5 can be stably performed; meanwhile, the worker can also detach the two connecting bolts 14 regularly through the bolt detaching mode, and then take the protective cover 12 out of the connecting column 13, so that the worker can overhaul or maintain the driving gear 11, the driven gear 10 and the motor 8 regularly.

As shown in fig. 4, six connecting pipes 22 communicated with the feeding hopper 2 are uniformly and fixedly arranged on the outer periphery of the feeding hopper 2, the connecting pipes 22 are positioned at the middle upper part of the feeding hopper 2, and a port of the connecting pipe 22 facing the inside of the feeding hopper 2 is connected with a filter mesh cloth 23 for sealing the connecting pipes 22; fixedly connected with air extractor 18 on frame 1, the air inlet department intercommunication of air extractor 18 has intake pipe 19, and the one end intercommunication that air extractor 18 was kept away from to intake pipe 19 has ring pipe 21, and six connecting pipes 22 are kept away from the one end of hopper 2 and all are linked together with ring pipe 21, and the air outlet department intercommunication of air extractor 18 has the one end of keeping away from air extractor 18 to extend to outdoor outlet duct 20. Therefore, when the air extractor 18 is started, the air overflowing from the hopper 2 is extracted through the air inlet pipe 19, the annular pipe 21 and the connecting pipe 22 and then discharged to the outside through the air outlet pipe 20, the arrangement of the filter screen cloth 23 enables the air in the hopper 2 to be extracted through the filter screen cloth 23, and the materials in the hopper 2 are difficult to be extracted from the connecting pipe 22; therefore, the effect of cleaning harmful gas discharged from the hopper 2 is achieved, and the possibility that the gas overflowed from the hopper 2 is sucked by surrounding workers to affect the health is reduced.

The implementation principle of the embodiment is as follows: when a worker observes that the materials in the hopper 2 are insufficient through the transparent plate 17, the materials can be poured into the storage box 5, the starting motor 8 drives the rotating shaft 4 to drive the storage box 5 to rotate upwards until one end, far away from the hopper 2, of the storage box 5 rotates to the position above the hopper 2, so that the materials can fall into the hopper 2 along the storage box 5 in an inclined mode, the effect of pouring the materials into the hopper 2 quickly and in a labor-saving mode is achieved, and the efficiency of a feeding process is improved; after the feeding is completed, the motor 8 is reversed to rotate the magazine 5 back to the initial state inclined downward with respect to the hopper 2, so that the magazine 5 can perform the re-feeding operation.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
