[0036] The present application provides a multi-stage material falling device, referring to Figures 1 to 5 The multi-stage material falling device comprises a first mounting seat 10 provided with a material falling hole 11; a first valve group comprising a first driving member 22 and a first material blocking member 21 movably connected to the first mounting seat 10, the first driving member 22 being configured to drive the first material blocking member 21 to move so as to block or release the material in the material falling hole 11; a telescopic chute 31 arranged at the lower end of the first mounting seat 10 and in abutment with the material falling hole 11; a second valve group comprising a second mounting seat 40 arranged at the lower end of the telescopic chute 31 and a second material blocking member 41 and a second driving member 42 arranged on the second mounting seat, the second driving member 42 being configured to drive the second material blocking member 41 to move so as to block or release the material in the telescopic chute 31; and a driving mechanism 50 configured to drive the telescopic chute 31 to extend or retract.

[0037] In the present embodiment, the driving mechanism can be a multi-section telescopic driving cylinder. During material discharging, the telescopic chute 31 can be driven by the driving mechanism 50 to extend, and the first valve group is opened to allow the material in the silo to fall into the telescopic chute 31 through the material falling hole 11 in the first mounting seat 10. After the telescopic chute 31 is filled with the material, the second valve group is opened to allow the material to fall into the carrier. The step-by-step discharging can reduce the kinetic energy of the material when falling, thereby reducing the reaction force of the carrier on the material and the collision between the materials, avoiding damage to the materials themselves. Meanwhile, the second material blocking member 41 can also play a certain buffering role and can slow down the impact of the material on the carriage or container.

[0038] In some embodiments, the driving mechanism 50 further comprises a hoist assembly 51 arranged on one side of the first mounting base 10, a transmission assembly comprising a first wheel body 53 arranged on the first mounting base 10, a second wheel body 54 arranged on the second mounting base 40, and a cable arranged around the first wheel body 53 and the second wheel body 54, one end of the cable being connected to the hoist assembly 51 and the other end being arranged on the first mounting base 10 or the second mounting base 40.

[0039] In the present embodiment, the first wheel body 53 and the second wheel body 54 can be pulleys, and the cable can be a rope, so that the transmission assembly can adopt the form of pulley transmission. The hoist assembly 51 can comprise a roller rotatably arranged on one side of the first mounting base 10 and a motor for rotating the roller, and one end of the rope is fixed to the roller. Rotation of the roller can wind or unwind the rope to drive the second mounting base 40 to ascend or descend.

[0040] In addition, the driving mechanism 50 further comprises a brake assembly connected to the hoist assembly 51, the brake assembly comprising a brake member 56 and a brake driving member for driving the brake member 56 to contact the roller. Specifically, a brake disc 52 can be arranged on the roller, and the brake driving member can be a pneumatic cylinder or a hydraulic cylinder arranged on the first mounting base 10. The brake assembly further comprises a connecting rod 57 hingedly connected to the first mounting base 10, the brake member 56 being rotatably arranged on one end of the connecting rod 57, and the other end of the connecting rod 57 being connected to the pneumatic cylinder or the hydraulic cylinder. The connecting rod 57 can be driven to swing by the brake driving member, thereby driving the brake member 56 to lock the brake disc 52. The brake assembly can be used to adjust the length of the telescopic roller 31 and prevent the telescopic roller 31 from falling at a high speed. The driving mechanism 50 further has the functions of height feedback, speed feedback, and overload alarm.

[0041] In some embodiments, further referring to Figure 4 , the driving mechanism 50 comprises a transmission assembly comprising a first wheel body 53 arranged on the first mounting base 10, a second wheel body 54 arranged on the second mounting base 40, and a cable arranged around the first wheel body 53 and the second wheel body 54, one end of the cable being arranged on the first mounting base 10 and the other end being arranged on the second mounting base 40, and a linear driving assembly 59 arranged on the first mounting base 10, a driving end of the linear driving assembly 59 being rotatably provided with a third wheel body 58, the cable being arranged around the third wheel body 58, and the linear driving assembly 59 being used to drive the third wheel body 58 to ascend or descend.

[0042] In the present embodiment, the first wheel body 53 and the second wheel body 54 and the third wheel body 58 can be sprockets, and the cable can be a chain, so that the transmission assembly can adopt the form of sprocket transmission. The second wheel body 54 and the third wheel body 58 correspond to movable pulleys, and the lifting of the third wheel body 58 can drive the chain to fold, thereby shortening the distance between the first mounting base and the second mounting base, and thus shortening the telescopic roller 31. The linear driving assembly 59 can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0043] In some embodiments, the multi-stage discharging device further comprises a telescopic shield 61, which is sleeved on the telescopic chute 31 and forms a gap between the telescopic shield 61 and the telescopic chute 31, and the upper end of the telescopic shield 61 is connected with the first mounting base 10. A cover plate 62 is arranged at the lower end of the telescopic shield 61, and the cover plate 62 can be received by the second mounting base 40 and move with the second mounting base 40. In this embodiment, the telescopic shield 61 can protect the telescopic chute 31. At the same time, during the discharging process, when the cover plate 62 is lowered to the upper end of the container or the carriage by the second mounting base 40, the cover plate 62 can be received by the upper end of the container or the carriage, so as to realize the overall or partial covering of the double-end opening of the container or the carriage, and reduce the external overflow of dust. Of course, the second mounting base 40 can also be driven by the driving mechanism 50 to continue to descend to a deeper part of the container or the carriage. After the discharging is completed, the second mounting base 40 moves upward and supports the cover plate 62 to continue to move upward. Further, the multi-stage discharging device further comprises a dust extraction pipeline communicated with the telescopic shield 61. The dust extraction pipeline can be arranged close to the cover plate 62 to avoid dust entering the gap between the rope protection pipe and the telescopic chute 31.

[0044] In some embodiments, two first material blocking members 21 are arranged in the first mounting base 10, and the first driving member 22 is used to drive the two first material blocking members 21 to move towards or away from each other. In this embodiment, the first material blocking member 21 can be two material blocking plates, and the ends of the two material blocking plates abut against each other to close the discharging port. When the two material blocking plates are driven by the first driving member 22 to move away from each other, the discharging port can be opened. When the two first material blocking members 21 are opened from the middle, the material falling will greatly reduce the scouring of the side wall of the telescopic chute 31.

[0045] Further, the first mounting seat 10 is also provided with two mounting cavities 12, which are arranged on both sides of the blanking hole 11, and a mounting passage is arranged between the mounting cavities 12 and the blanking hole 11. The two first material blocking pieces 21 are arranged in the mounting passage and are arranged in layers. The overlapping areas of the two first material blocking pieces 21 are respectively provided with blanking notches 23 corresponding to the blanking hole 11. In the embodiment, the two first material blocking pieces 21 can also be selected as blocking plates, which are arranged in layers to avoid the situation of being not tightly closed. In addition, the inner wall of the mounting cavity 12 is also rotatably provided with a roller 24, which is used for supporting the two first material blocking pieces 21. The arrangement of the roller 24 can avoid direct friction between the two blocking plates, so that the movement of the first material blocking piece 21 is more smooth. The roller 24 and the first driving piece 22 are arranged in the mounting cavity 12 and are completely separated from the material, which can greatly improve the working life and stability of the system in a harsh dust environment, improve the overall working level of the system. The second material blocking piece 41 in the second valve group is rotatably arranged on the second mounting seat 40, and the second driving piece 42 drives the second material blocking piece 41 to swing to correspondingly open the opening at the bottom of the telescopic chute 31. Of course, the above-mentioned second valve group can also be symmetrically provided with two second material blocking pieces 41 to form a double-door structure. The second driving piece 42 can be selected as an oil cylinder.

[0046] The application also provides a storage system, which comprises the multi-stage blanking device and a material bin arranged at the upper end of the first mounting seat 10 and connected with the blanking hole 11.

[0047] In the embodiment of the application, the working principles of the multi-stage blanking device and the storage system are as follows:

[0048] When the telescopic chute 31 is shrunk to the top, the second valve group is in a closed state, and after the first valve group is opened, the material enters the inside of the telescopic chute 31. After the inside of the telescopic chute 31 is filled with the material, the telescopic chute 31 is lowered to the bottom. Since the material in the chute is always in a full cylinder state, the injection of the material has no great impact.

[0049] After the telescopic chute 31 is lowered to the bottom, the second valve group is opened, and the material starts to enter the loading container. The chute slowly rises, and after the loading weight reaches the program setting value, the first valve group is closed. The chute continues to rise, and after the material in the chute is completely unloaded, the second valve group is closed. Then, the first valve group can be opened for the second loading.

[0050] The dustproof cover on the outside of the telescopic chute 31 is a follower. When the telescopic chute 31 is lowered, the dustproof cover is lowered to the container opening under the action of gravity and is covered by the cover plate 62. When the telescopic chute 31 is discharging, a closed space is formed, which can effectively prevent dust overflow in cooperation with an external dust removal system. When the telescopic chute 31 is finished discharging and is lifted to the container opening, the dustproof cover bottom frame will hook the telescopic chute 31 and rise together with the telescopic chute 31.

[0051] In addition, the multi-stage blanking device is provided with two sets of gates at the top and bottom, which can cooperate with the weighing and metering system to accurately control the weight of the loading. The specific control process is as follows: when the weighing and metering system detects that the weight is close to the preset weight, the first valve group at the top is closed first. At this time, the telescopic chute 31 still has some materials inside, the second valve group can be controlled, and the weight of the materials can be accurately controlled to achieve the accurate preset weight of the materials.

[0052] The above are only part or preferred embodiments of the present application, neither the text nor the drawings can limit the scope of protection of the present application, any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the scope of protection of the present application.
