[0016] Through the design of the storage silo feeder, during operation, the upstream tipping and unloading device pours tobacco into the storage silo feeder. The active and driven chain rollers inside the storage silo feeder drive the conveyor belt three to move, thereby achieving uniform distribution of tobacco. When the photoelectric switch on the intermediate material level window detects tobacco, the conveyor belt three stops moving, and the upstream tipping and unloading device can continue to unload until the photoelectric switch on the tail material level window detects tobacco, at which point the upstream tipping and unloading device stops feeding. At the same time, the material leveling roller transmission device drives the material leveling roller to move in a circular motion, so that the tobacco falls evenly onto the bidirectional guide belt conveyor through the drop hopper two. When the bidirectional guide belt conveyor stops running, the storage silo feeder stops simultaneously.

[0017] With the design of a bidirectional feeder belt, the left discharge hopper connects to the left compartment, and the right discharge hopper connects to the right compartment. When the left compartment is running, the bidirectional feeder belt rotates to the left, feeding the tobacco into the left compartment. When the right compartment is running, the bidirectional feeder belt rotates to the right, feeding the tobacco into the right compartment, thus realizing the bidirectional conveying of tobacco and facilitating adaptation with the two compartments at the bottom.

[0018] Through the design of the hopper, when the pneumatic conveying system for tobacco connected to the left hopper needs material, the second conveyor belt in the left hopper moves to the right, and the tobacco enters the three-way distributor and the discharge bend through the first hopper, finally entering the pneumatic conveying system pipeline. When the pneumatic conveying system for tobacco connected to the right hopper needs material, the second conveyor belt in the right hopper moves to the left, and the tobacco enters the three-way distributor and the discharge bend through the first hopper, finally entering the pneumatic conveying system pipeline, thus realizing the left and right conveying of tobacco.

When the right bin 26 is running, the bidirectional feed conveyor 2 rotates to the right to feed the tobacco into the right bin 26, thereby realizing the bidirectional conveying action of the tobacco and facilitating adaptation with the two bins 26 at the bottom.

[0033] See Figures 7-8The hopper 3 includes two symmetrically arranged hopper bodies 26. Each hopper body 26 has a support leg 47 connected to its bottom. Each hopper body 26 has a rear viewing window 48 on its side and a hopper inlet 28 on its top. The two hopper inlets 28 are respectively connected to the left discharge hopper 19 and the right discharge hopper 25.

The transparent metering window 29 is equipped with a material level detection photoelectric sensor 27. The other side of the hopper body 26 has a tobacco pre-filling observation window 31. The tobacco pre-filling observation window 31 is equipped with a tobacco pre-filling detection photoelectric sensor 30. The top of the bin 26 also has a supplementary air window 33 on one side. A discharge hopper 43 is located on one side of the bottom of the bin 26. A three-way distributor 46 is connected to the discharge end of the discharge hopper 43. The two output ends of the three-way distributor 46 are connected to one end of a discharge bend 44. The other end of the discharge bend 44 is connected to a transparent tobacco suction tube 32. The transparent tobacco suction tube 32 is connected to a tobacco pneumatic conveying system. A driven belt roller 35 and a driven belt roller 41 are rotatably connected to the inside of the bin 26 on both sides. The driven roller 35 and the driven roller 41 are connected by a second conveyor belt 37. The movable end of the driven roller 41 extends through the outside of the bin 26 and is connected to the belt drive reducer 45.

A material leveling rake roller 42 is rotatably connected inside the bin 26 and above the first hopper 43. The rotating shaft end of the material leveling rake roller 42 extends through the outside of the bin 26 and is connected to the material leveling rake roller. The drive reducer 34 is connected; through the design of the hopper 3, when the tobacco pneumatic conveying system connected to the left hopper 26 needs material, the second conveyor belt in the left hopper 26 moves to the right, and the tobacco enters the three-way distributor 46 and the discharge bend 44 through the first drop hopper 43 and finally enters the tobacco pneumatic conveying system pipeline. When the tobacco pneumatic conveying system connected to the right hopper 26 needs material, the second conveyor belt in the right hopper 26 moves to the left, and the tobacco enters the three-way distributor 46 and the discharge bend 44 through the first drop hopper 43 and finally enters the tobacco pneumatic conveying system pipeline, thereby realizing the left and right conveying of tobacco.

[0034] See Figure 8 The top of the hopper 26 is vertically connected to a manual material handling plate 36 and a tobacco shred guide plate 38. The tobacco shred guide plate 38 and the manual material handling plate 36 are bolted to the hopper 26. The hopper 3 has a manual material handling function. When manual material handling is required, the manual material handling plate 36 is lifted and the conveyor belt is manually adjusted to run in the opposite direction to retrieve material from the tail of the hopper 26 for process testing, etc.

[0035] See Figures 2-3 The storage feeder 1 includes a frame 49, with support legs 59 at the bottom and a guardrail 60 at the top. A discharge hopper 50 is located at the front end of the frame 49. A drive chain roller 51 and a driven chain roller 52 are rotatably connected to the front and rear sides of the frame 49, respectively, via a chain drive. A conveyor belt 3 is fitted between the drive chain roller 51 and the driven chain roller 52, and is adapted to fit the discharge hopper 50. Several material leveling rollers are rotatably connected inside the frame 49, above the end of the conveyor belt 3 near the discharge hopper 50. 53. A material leveling roller transmission device 54, which cooperates with the material leveling roller 53, is installed on the side of the frame 49. The material leveling roller transmission device 54 includes three sets of pulleys, which are respectively connected and fixed to the shaft ends of the three material leveling rollers 53. Adjacent sets of pulleys are connected by belts. The end of the middle material leveling roller 53 extends through the outside of the frame 49 and is connected to the output end of the motor. The motor drives the middle material leveling roller 53 to rotate. The middle material leveling roller 53 is synchronously linked with the belts through the three sets of pulleys, thereby driving the three sets of material leveling rollers 53 to rotate synchronously, thus realizing the material leveling action. The two sides of the frame 49 Each side of the frame 49 is provided with a tail-end material level viewing window 55 and a middle material level viewing window 56. The front end of the frame 49 is provided with a front material level viewing window 57. The front end of the second hopper 50 is provided with a hopper observation window 58. The sides of the frame 49 are provided with a rear-end chain operation observation window 61 and a front-end chain operation observation window 62 that cooperate with the chain. The bottom of the frame 49 is provided with a dustproof support plate 63 that cooperates with the conveyor belt. The drive chain roller 51, the drive roller 7, the material leveling rake roller drive reducer 34, and the belt drive reducer 45 are all equipped with drive motors. The tail-end material level viewing window 55 and the middle material level viewing window 56 are both equipped with photoelectric switches. During operation, the upstream tipping and unloading device pours tobacco into the storage feeder 1. The driving chain roller 51 and driven chain roller 52 in the storage feeder 1 drive the conveyor belt 3 to move, thereby achieving uniform distribution of tobacco. When the photoelectric switch on the intermediate material level window 56 detects tobacco, the conveyor belt 3 stops moving, and the upstream tipping and unloading device can continue to pour material until the photoelectric switch on the tail material level window 55 detects tobacco. At the same time, the material leveling roller transmission device 54 drives the material leveling roller 53 to move in a circular motion, so that the tobacco falls evenly onto the bidirectional guide belt conveyor 2 through the drop hopper 2 50. When the bidirectional guide belt conveyor 2 stops running, the storage feeder 1 stops synchronously.

[0036] Whether the silo feeder 1 feeds material depends solely on the photoelectric switch of the tail-end material level window 55. If the photoelectric switch of the tail-end material level window 55 detects tobacco shreds, no feeding is required; otherwise, feeding is required. Before feeding material, the photoelectric switch on the intermediate material level window 56 pre-detects whether there are tobacco shreds. If so, the belt does not move, and the upstream tilting and unloading device directly unloads material until the photoelectric switch on the tail-end material level window 55 detects tobacco shreds, at which point unloading stops. If not, the feeding process described above continues.

[0037] The circuits and electronic components, modules and controllers, or the heat dissipation holes and maintenance doors in the space of the adapted electrical equipment are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this application does not involve improvements to software and methods or heat dissipation and maintenance.

[0038] In operation, the feeding end of the storage feeder 1 is signal-interlocked with the upstream tipping and unloading equipment. The upstream tipping and unloading equipment pours tobacco into the storage feeder 1. The driving chain roller 51 and driven chain roller 52 inside the storage feeder 1 drive the conveyor belt 3 to move, thereby achieving uniform distribution of tobacco. When the photoelectric switch on the intermediate material level window 56 detects tobacco, the conveyor belt 3 stops moving, but the upstream tipping and unloading equipment can continue to unload until the photoelectric switch on the tail material level window 55 detects tobacco, at which point the upstream tipping and unloading equipment stops feeding. At the same time, the material leveling roller transmission device 54 drives the material leveling roller 53 to move in a circular motion, so that the tobacco falls evenly onto the bidirectional guide belt conveyor 2 through the drop hopper 2 50. When conveyor belt 2 stops operating, silo feeder 1 stops simultaneously. The left discharge hopper 19 connects to the left silo 26, and the right discharge hopper 25 connects to the right silo 26. When the left silo 26 is operating, the bidirectional feeder belt 2 rotates to the left, feeding tobacco into the left silo 26. When the right silo 26 is operating, the bidirectional feeder belt 2 rotates to the right, feeding tobacco into the right silo 26. When silo 3 stops operating, the bidirectional feeder belt 2 stops simultaneously. The operation of the bidirectional feeder belt 2 is as follows: the motor drives the drive roller 7 and driven roller 18 to rotate, which in turn moves the first conveyor belt. The movement of the first conveyor belt moves the tobacco. When the first conveyor belt moves to the left, the tobacco passes through… The tobacco shreds are conveyed to the left-side bin 26. When the conveyor belt moves to the right, the tobacco shreds are conveyed to the right-side bin 26. When the material level detection photoelectric sensor 27 does not detect tobacco shreds, the bidirectional feed conveyor belt 2 starts to feed. The driven roller 35 and the driven roller 41 drive the second conveyor belt forward, thereby achieving uniform distribution of tobacco shreds. When the tobacco shred pre-filling detection photoelectric sensor 30 detects tobacco shreds, the second conveyor belt stops moving, and feeding continues until the material level detection photoelectric sensor 27 detects tobacco shreds, at which point the feeding action stops. Before each feeding, the tobacco shred pre-filling detection photoelectric sensor 30 pre-checks whether there are tobacco shreds. If there are, the second conveyor belt does not move, and the bidirectional feed conveyor belt 2 discharges the tobacco shreds until the material level detection photoelectric sensor 27 detects tobacco shreds. If tobacco is detected, the feeding process continues as described above. The discharge bend 44 is connected to the tobacco pneumatic conveying system via a pipeline. When the tobacco pneumatic conveying system connected to the left hopper 26 requires material, the second conveyor belt in the left hopper 26 moves to the right, and the tobacco enters the three-way distributor 46 and the discharge bend 44 through the first drop hopper 43, finally entering the tobacco pneumatic conveying system pipeline. When the tobacco pneumatic conveying system connected to the right hopper 26 requires material, the second conveyor belt in the right hopper 26 moves to the left, and the tobacco enters the three-way distributor 46 and the discharge bend 44 through the first drop hopper 43, finally entering the tobacco pneumatic conveying system pipeline. When the tobacco pneumatic conveying system stops requiring material, the hopper 3 stops simultaneously.

[0039] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
