[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1, reference Figure 1-6 A straw processing rotary multi-bin feeder comprises a base 1 with braked universal wheels fixedly mounted at the four corners of the bottom, the top of the base 1 is connected to a chassis 2 through a feeding height adjustment mechanism, and the chassis 2 is provided with a rotary multi-bin feeding mechanism; In this embodiment, the rotary multi-bin feeding mechanism includes a rotating shaft 3 rotatably mounted on the top of the chassis 2, a turntable 4 coaxially welded to the outer wall of the top end of the rotating shaft 3, four straw feeders arranged on the turntable 4 and distributed in a ring shape, a driving motor 5 fixed to the side wall of the chassis 2 by bolts, an active bevel gear 6 fixedly mounted on the output shaft of the driving motor 5, and a driven bevel gear 7 fixedly mounted on the bottom end of the rotating shaft 3. The output shaft of the driving motor 5 passes through one side of the chassis 2, and the active bevel gear 6 and the driven bevel gear 7 are meshed with each other. Then, the active bevel gear 6 is controlled to rotate by the driving motor 5, and then the driven bevel gear 7 meshed with the active bevel gear 6 will drive the turntable 4 welded on the top end of the rotating shaft 3 to rotate, thereby realizing the automatic rotation switching effect of the four straw feeders connected to the turntable 4; The effects of the rotary multi-bin feeding mechanism are as follows: first, the feeder has multiple independent silos that can store straws of different types and states at the same time; second, during feeding, different silos can be switched by rotation to feed in order to meet the processing of straws of different states by straw processing equipment; third, by rotating the straw feeder, its feeding direction can be flexibly adjusted to meet the feeding needs of straw processing equipment in different directions; finally, after the silo 11 is empty, the traditional single-bin feeder needs to stop and refill before continuing the straw feeding operation, while the present invention can quickly switch to the next full silo 11 in the empty state after one silo 11 is fed through repeated rotation and switching of the four straw feeders, and can also refill the empty silo 11 at the same time, without stopping for adjustment, thereby effectively improving work efficiency; In this embodiment, the straw feeder includes a reinforcing connecting rib 8 welded to the outer wall of the circumference of the turntable 4, a supporting frame 9 welded to the outer wall of one end of the reinforcing connecting rib 8, a feeding cylinder 10 welded to the outer wall of the supporting frame 9, a silo 11 fixedly connected to one end of the top of the feeding cylinder 10, a variable speed screw conveying component, a hot air drying component and an angle-adjustable feeding component; Furthermore, the variable speed spiral conveying assembly includes a transmission shaft 12 rotatably mounted in the feeding barrel 10, a spiral conveying blade 13 welded on the outer wall of the transmission shaft 12 and located in the feeding barrel 10, a support seat 14 welded to the outer wall of one end of the bottom of the feeding barrel 10, a variable speed motor 15 fixed to the outer wall of the bottom of the support seat 14 by bolts, a driving pulley 16 fixedly mounted on the output shaft of the variable speed motor 15 and a driven pulley 17 fixedly mounted on one end of the transmission shaft 12, the driving pulley 16 and the driven pulley 17 are connected to each other through the same transmission belt 18, and a frequency converter 19 electrically connected to the variable speed motor 15 is fixed to the outer wall of one side of the support seat 14 by bolts; When the variable speed spiral conveying assembly is in use: the variable speed motor 15 drives the active pulley 16 to rotate, and then under the transmission effect of the transmission belt 18, the driven pulley 17 drives the spiral conveying blade 13 on the transmission shaft 12 to rotate to automatically convey the straw raw material in the silo 11 to achieve the effect of automatic feeding, and the frequency converter 19 adjusts the speed of the variable speed motor 15 to achieve precise control of the conveying speed, and then the feeding speed can be precisely controlled according to the actual needs of straw processing; Further, the hot air drying assembly includes a fan base 20 welded to the outer wall of the feeding barrel 10, a temperature-controlled hot air blower 21 fixed to the outer wall of the top of the fan base 20 by bolts, and a shunt pipe 22 fixedly connected to the top of the feeding barrel 10, and the blowing end of the temperature-controlled hot air blower 21 is connected to the shunt pipe 22 through a pipeline; When the hot air drying component is in use: the temperature-controlled hot air blower 21 is adjusted to a suitable temperature, and then the hot air sent by the temperature-controlled hot air blower 21 is evenly transported to the feeding tube 10 by the shunt pipe 22, so as to dry some relatively wet straw raw materials to a certain extent, and avoid the situation that the over-wet straw raw materials are easy to cause blockage due to the high viscosity; Furthermore, the angle-adjustable feeding assembly includes a feeding hose 23 fixedly connected to the open end of the feeding barrel 10, a solenoid valve 24 installed on the feeding hose 23, and an electric push rod 25 hinged between the feeding hose 23 and the feeding barrel 10. The feeding hose 23 is a universal metal hose, and the electric push rod 25 is tilted. When the angle-adjustable feeding assembly is in use: the feeding angle of the feeding hose 23 can be flexibly adjusted through the hinged electric push rod 25, so that the straw can better enter different straw processing equipment.

[0025] Example 2, reference Figure 1-2 and Figure 7-8 This embodiment is optimized on the basis of the embodiment 1, specifically: the feeding height adjustment mechanism includes a fixed frame 26 welded to the top outer wall of the base 1, a lifting frame 27 welded to the bottom outer wall of the chassis 2 and inserted into the fixed frame 26, a rack 28 fixedly connected to the rear outer wall of the lifting frame 27, a driving gear 29, a guide assembly and a reduction drive assembly; Furthermore, the guide assembly includes two guide bars 30 welded to the outer walls of both sides of the lifting frame 27 and two guide grooves 31 opened on the inner walls of both sides of the fixed frame 26. The two guide bars 30 are slidably connected to the two guide grooves 31 respectively, so that a good guiding effect can be achieved during the lifting process of the lifting frame 27.

The worm 34 and the worm wheel 36 are both located in the reduction box 32, and the driving gear 29 is fixedly sleeved on the reduction shaft 35 and meshed with the rack 28. In this way, the reduction and self-locking performance after the worm 34 and the worm wheel 36 are meshed can ensure the stability of the lifting frame 27 during the lifting process. In the specific implementation of this embodiment: the worm 34 is controlled to rotate by the stepper motor 33, and then the worm wheel 36 meshing with the worm 34 drives the driving gear 29 on the reduction shaft 35 to rotate, and then the rack 28 meshing with the driving gear 29 drives the lifting frame 27 to make a linear motion. In this way, the lifting frame 27 can be controlled to make a lifting motion by the positive and negative rotation of the output shaft of the stepper motor 33, so that the feeding height of the straw feeder can be flexibly adjusted, which can better meet the feeding requirements of straw processing equipment at different heights.
