[0029] like Figure 1-4 The figure shows an automatic discharge device comprising a loading assembly, a discharge assembly, and a mounting frame. The loading assembly, used to control discharge, comprises a hopper 1 and a pneumatic gate 2 mounted on the hopper 1. The discharge assembly, used to discharge material into a silo and control the start of discharge, comprises a positioning member for aligning the silo opening and a conveying member for injecting material into the silo. The mounting frame comprises a mounting plate 3 and several struts 4 supporting the mounting plate 3. The mounting plate 3 is provided with a discharge opening. The upper portion of the discharge opening corresponds to the hopper 1, while the lower portion corresponds to the discharge assembly. The operation of both the loading and discharge assemblies is controlled by a control system.

[0030] In order to realize the placement of the device at the silo mouth, a positioning piece is provided, which includes a positioning mechanism and a moving mechanism for driving the positioning mechanism to move up and down; the positioning mechanism includes an induction ring 5, a connecting sleeve 6 and a plurality of proximity switches 3 7, the induction ring 5 is provided below the connecting sleeve 6, and the connection form can be connected to the connecting sleeve 6 through a connecting column. When connected, there is a movable spacing between the induction ring 5 and the connecting sleeve 6. When the induction ring 5 encounters external force, it will approach the bottom end of the connecting sleeve 6. The plurality of proximity switches 3 7 are evenly distributed at the bottom of the connecting sleeve 6 and can be identified when the induction ring 5 approaches.

[0031] When the device moves to the position of the silo opening, it is necessary to transmit a signal to the control system through the cooperation of the induction ring 5 and the proximity switch 3 7. Here, it is the silo opening, and the material can be discharged. Therefore, it is necessary to make the induction ring 5 drop to the silo opening at the position opposite to the silo opening to trigger the signal. Therefore, a moving mechanism that can make the induction ring 5 move up and down is provided. The moving mechanism includes a telescopic bag 8 connected to the upper end of the connecting sleeve 6 and a driving mechanism that drives the telescopic bag 8 to retract. The driving mechanism includes a motor 9 with a reducer provided on the mounting plate 3 and a driving shaft 10 connected to the output end of the motor 9. In order to fix the driving mechanism, the driving mechanism is provided. The driving shaft 10 has bearings and fixed blocks at both ends. The driving shaft 10 is equipped with a first disc 11, a second disc 12, and a third disc 13, which are evenly distributed in sequence and each have a winding groove. Each of the first disc 11, the second disc 12, and the third disc 13 is wound with a wire rope. The other end of the wire rope is connected to the upper end of the connecting sleeve 6. Three connecting hooks 14 are evenly distributed around the upper end of the connecting sleeve 6, which connect to the wire ropes of the first disc 11, the second disc 12, and the third disc 13. The outer wall of the telescopic bag 8 is longitudinally provided with several evenly distributed fixing rings 33 through which the wire ropes pass. The portion between the wire ropes on the first disc 11, the second disc 12, and the third disc 13 and the corresponding connecting hooks 14 is equipped with guide wheels 34 located on the mounting plate 3. The three guide wheels 34 are evenly distributed along the circumference of the telescopic bag 8. When the motor 9 is started, the first disc 11, the second disc 12 and the third disc 13 are driven to rotate under the action of the drive shaft 10. During forward rotation, the wire rope is tightened, and the wire rope drives the connecting sleeve 6 to rise, and the telescopic bag 8 to shrink; during reverse rotation, the wire rope is released, and it descends together with the connecting sleeve 6, and the telescopic bag 8 is extended, thereby realizing the rising and falling of the induction ring 5 connected to the connecting sleeve 6.

[0032] In order to achieve the control of shutting down the motor 9, a proximity switch 15 and a proximity switch 2 16 are provided on the mounting plate 3. The proximity switch 15 cooperates with the positioning mechanism. When the positioning mechanism rises to the top, the proximity switch 15 senses and gives a signal, and the motor 9 stops working. In this scheme, the proximity switch 15 is arranged between the second disc 12 and the third disc 13 and close to the outside; the part of the drive shaft 10 close to the third disc 13 is provided with an external thread 17 that drives the third disc 13 to move radially. The proximity switch 2 16 is arranged near the wire rope connected to the third disc 13, and a lifting ear 19 assembly that cooperates with the proximity switch 2 16 is provided next to the proximity switch 2 16. The lifting ear 19 assembly includes a fixed plate 18 provided on the mounting plate 3, a lifting ear 19 hinged to the fixed plate 18 and located at the top of the proximity switch 2 16, and the lifting ear 19 is provided with a lifting ring 20 sleeved on the wire rope of the third disc 13. The second proximity switch 16 is provided to protect the telescopic bag 8. When the telescopic bag 8 is fully unfolded and still does not touch the silo opening, the wire rope will contact the lifting lug 19 and cause the lifting lug 19 to touch the second proximity switch 16, triggering a signal. The motor 9 will stop working and no longer rotate, preventing the telescopic bag 8 from being entangled.

[0033] In order to facilitate the transportation of materials from the hopper 1 and cooperate with the telescopic bag 8 and the connecting sleeve 6, the conveying part includes a telescopic tube that cooperates with the telescopic bag 8 and is located inside the telescopic bag 8, and a chute 21 connected under the telescopic tube. The telescopic tube is a prior art and its structure is not described in detail here. When the telescopic bag 8 is expanded or tightened, the telescopic tube can also be extended or contracted; the chute 21 as a whole can also be extended and contracted, including a number of pipes that are overlapped and can be extended and contracted. The innermost layer of the pipe is connected to the telescopic tube, and a telescopic assembly is provided between the outermost layer of the pipe and the connecting sleeve 6, and a material level sensor 22 is provided at the bottom end of the pipe to sense the position of the material and send a signal when the material is full.

[0034] When the device is placed on the bin opening, in order to avoid dust flying when discharging, the chute 21 is inserted into the bin to discharge material. In order to realize the up-down control of the chute 21, a telescopic assembly is arranged, which includes a telescopic part arranged opposite in the connecting sleeve 6. The barrel of the connecting sleeve 6 is a hollow cavity. The telescopic assembly and the proximity switch 7 are arranged in the cavity. The telescopic part includes an electric push rod 23 arranged at the bottom of the connecting sleeve 6, two driving wheels 24 arranged side by side at the top end of the electric push rod 23, two driven wheels 25 arranged respectively at the bottom of the electric push rod 23 on both sides, and two steel wires. One end of one of the steel wires is fixed to the mounting seat of the left driven wheel 25, and the other end passes around one of the driving wheels 24 and then winds out from the right driven wheel 25. One end of the other steel wire is fixed to the mounting seat of the right driven wheel 25, and the other end passes around the other driving wheel 24 and then winds out from the left driven wheel 25. The top of the connecting sleeve 6 is provided with wheel one 26 and wheel two 27 opposite to the driven wheels 25, and wheel three opposite to the electric push rod 23. Wheel four 28 is arranged between wheel one 26 and wheel three, and wheel five 29 is arranged between wheel two 27 and wheel three. The outer wall of the outermost pipe is provided with plate one 30 and plate two 31 arranged opposite with connecting holes. The steel wire is connected from plate one 30 as the connection starting point, and then passes around wheel one 26, wheel four 28, wheel three, wheel five 29 and wheel two 27 in sequence and is fixed to plate two 31. The steel wire wound out from the right driven wheel 25 is connected to wheel five 29, and the steel wire wound out from the left driven wheel 25 is connected to wheel four 28. The connecting buckles 32 are arranged on wheel four 28 and wheel five 29. The steel wire wound out from the right driven wheel 25 is connected to the connecting buckle 32 on wheel five 29, and the steel wire wound out from the left driven wheel 25 is connected to the connecting buckle 32 on wheel four 28. During use, the electric push rod 23 is pushed up, the steel wire connected to the driving wheel 24 is also pushed up, the steel wire pulls wheel four 28 and wheel five 29, and the steel wire is pulled down with force. The end connected to the chute 21 is lifted, that is, the chute 21 is retracted; on the contrary, the chute 21 is extended.

[0035] Working principle: The utility model provides an automatic discharging device. When in use, the motor 9 drives the first disc 11, the second disc 12 and the third disc 13 to rotate, and the connecting sleeve 6 and the conveying piece together with the telescopic cloth bag 8 descend, and the induction ring 5 hits the hopper mouth. The induction ring 5 moves up and is sensed by the proximity switch 7, which sends a signal to move down and stop. At the same time, the electric push rod 23 drives the wire rope to lower the bottom chute 21 into the hopper. The pneumatic gate 2 receives the signal and opens to discharge the material. When the material is full, the level meter 22 senses and gives a signal. The countdown pneumatic gate 2 closes, and the electric push rod 23 moves at the same time, the bottom chute 21 is retracted, and the stored material is discharged after a delay. The motor 9 works, pulling the connecting sleeve 6, the conveying piece together with the telescopic cloth bag 8 to rise. When it rises to the top, the proximity switch 15 senses and gives a signal, the motor 9 stops working, and the discharging is completed.
