[0040] like Figures 1 to 3 As shown, a device 10 for fully emptying ton bags containing residual materials in one embodiment includes a silo 100, a clamping mechanism 200, an air intake and exhaust mechanism 300, and a high-frequency vibration mechanism 400. The silo 100 is formed with a silo opening 102. The clamping mechanism 200 is disposed on the outer wall of the silo 100 and is used to clamp the opening of the ton bag 20, aligning it with the silo opening 102. This prevents the bag opening from shaking relative to the silo opening 102 and causing residual materials to be scattered. The opening of the ton bag 20 is thus fixedly positioned relative to the silo opening 102. The air intake and exhaust mechanism 300 is used to inflate the ton bag 20, allowing the residual materials within the ton bag 20 to be reliably discharged. The high-frequency vibration mechanism 400 is disposed on the outer wall of the silo 100 and is used to vibrate the ton bag 20 after inflation, ensuring that the residual materials within the ton bag 20 are reliably released from the silo 20.

[0041] The above-mentioned ton bag residual sufficient unloading device 10, the silo 100 is formed with a silo opening 102, when the ton bag 20 is transported to the top of the silo opening 102, the clamping mechanism 200 is clamped on the bag opening of the ton bag 20 to set the bag opening toward the silo opening 102; the air intake and exhaust mechanism 300 inflates the ton bag 20, and the high-frequency vibration mechanism 400 vibrates the ton bag 20 after the ton bag 20 is inflated, so that the residual material in the ton bag 20 can be reliably poured out, which solves the problem of a large amount of residual material in the ton bag 20 after feeding.

[0042] In one embodiment, the vibration frequency of the high-frequency vibration mechanism 400 is 3,000 times / min to 30,000 times / min, so that the high-frequency vibration mechanism 400 can reliably vibrate the ton bag 20 .

[0043] like Figure 3 and Figure 4 As shown, in one embodiment, the ton bag residual sufficient unloading device 10 also includes an air vibration mechanism 500, the silo 100 is provided with a collecting chamber 104 and a mounting hole 106, the collecting chamber 104 is communicated with the mounting hole 106 and the silo port 102 respectively, the air vibration mechanism 500 is penetrated into the mounting hole 106 and connected to the silo 100, the air outlet end of the air vibration mechanism 500 is communicated with the collecting chamber 104, and the air vibration mechanism 500 is used to perform low-frequency vibration on the inner membrane of the ton bag 20 so that the powder in the ton bag 20 can be discharged.

[0044] In one embodiment, the air vibration mechanism 500 is used to perform low-frequency vibration on the inner membrane of the ton bag 20 when the high-frequency vibration mechanism 400 is working, so that the air vibration mechanism 500 and the high-frequency vibration mechanism 400 act on the ton bag 20 at the same time, that is, when the high-frequency vibration mechanism 400 performs high-frequency vibration on the outer wall of the ton bag 20, the air vibration mechanism 500 simultaneously performs low-frequency vibration on the inner membrane of the ton bag 20, thereby allowing the powder in the ton bag 20 to be discharged quickly and reliably.

[0045] In one embodiment, the vibration frequency of the air vibration mechanism 500 is 300 to 1000 times / min. And / or, in one embodiment, the air intake and exhaust volume of the air vibration mechanism 500 is 1 / 100 to 1 / 50 of the volume of the big bag 20.

[0046] like Figure 3As shown, in one embodiment, the clamping mechanism 200 includes a clamping drive assembly 210 and a clamping bracket 220. The clamping drive assembly 210 is mounted on the outer wall of the silo 100, and the clamping bracket 220 is connected to the power output end of the clamping drive assembly 210. The clamping bracket 220 is used to clamp the bag opening so that the bag opening is positioned toward the silo opening 102. In this embodiment, there are two clamping drive assemblies 210, which are arranged opposite each other, and the power output ends of the two clamping drive assemblies 210 are both connected to the clamping bracket 220. The two clamping drive assemblies 210 jointly drive the clamping bracket 220 to move relative to the silo opening 102.

[0047] like Figure 3 As shown, further, the clamping drive assembly 210 includes a driving cylinder 212 and a clamping plate 214. The driving cylinder 212 is mounted and fixed to the outer wall of the silo 100, the clamping plate 214 is mounted and fixed to the power shaft of the driving cylinder 212, and the clamping bracket 220 is fixedly connected to the clamping plate 214. In this embodiment, the clamping plate 214 is welded to the circumference of the clamping bracket 220, so that the clamping plate 214 and the clamping bracket 220 are fixedly connected. Specifically, the clamping bracket 220 is a silicone sealing ring, which makes the clamping bracket 220 have good elasticity, thereby making the clamping bracket 220 better sealed and fitted to the ton bag 20. Furthermore, the clamping bracket 220 is annular, and the clamping bracket 220 is provided with a plurality of positioning blocks distributed along the circumferential direction, so that the clamping bracket 220 can be better clamped and positioned at the bag opening of the ton bag 20. In this embodiment, the clamping bracket 220 and each positioning block are made of silicone, allowing the clamping bracket 220 to better position the bag opening of the ton bag 20. Furthermore, each positioning block is provided with a positioning matching bevel, which abuts the outer wall of the ton bag 20, allowing each positioning block to better abut the ton bag 20.

[0048] like Figure 2 and Figure 3As shown, in one embodiment, the high-frequency vibration mechanism 400 includes a vertically movable drive assembly 410, a connecting assembly 420, a transverse sliding frame 430, and a vibrator 440. The vertically movable drive assembly 410 is mounted on the outer wall of the silo 100. The connecting assembly 420 is connected to the power output end of the vertically movable drive assembly 410, so that the vertically movable drive assembly 410 drives the connecting assembly 420 to move up and down in the vertical direction. The transverse sliding frame 430 is mounted on the connecting assembly 420, so that the transverse sliding frame 430 moves up and down with the connecting assembly 420. The vibrator 440 is slidably connected to the transverse sliding frame 430, so that the vibrator 440 slides horizontally relative to the transverse sliding frame 430, thereby enabling the vibrator 440 to better act on the outer peripheral wall of the ton bag 20. In this embodiment, the connecting assembly 420 is slidably connected to the outer wall of the silo 100. There are two high-frequency vibration mechanisms 400, which are arranged on opposite sides of the silo 100 so that the two high-frequency vibration mechanisms 400 act on the ton bag 20 simultaneously. Furthermore, the vibrator 440 includes a vibrator body and a sliding mounting platform. The vibrator body is fixedly connected to the sliding mounting platform. The sliding mounting platform is provided with a sliding guide block. The transverse sliding frame 430 has a transverse slide groove. The sliding guide block is located in the transverse slide groove and is slidably connected to the transverse sliding frame 430.

[0049] like Figure 3 As shown, in one embodiment, there are multiple vibrators 440, which are spaced apart and slidably connected to the transverse sliding frame 430, so that the multiple vibrators 440 can slide laterally relative to the transverse sliding frame 430, thereby enabling the multiple vibrators 440 to act on the outer peripheral wall of the ton bag 20. In this embodiment, there are four vibrators 440, two of which are located above the transverse sliding frame 430, and the other two vibrators 440 are located below the transverse sliding frame 430.

[0050] like Figure 3 、 Figure 5 and Figure 6As shown, in one embodiment, the connection assembly 420 includes a fixed bracket 422, a rotary drive member 424, and a movable bracket 426. One end of the fixed bracket 422 is fixedly connected to the power output of the vertical drive assembly 410. The power output of the rotary drive member 424 is rotatably connected to the fixed bracket 422. The mounting base of the rotary drive member 424 is fixedly connected to the movable bracket 426, so that the rotary drive member 424 drives the movable bracket 426 to rotate relative to the fixed bracket 422, thereby better adjusting the position of the vibrator 440 relative to the ton bag 20 and allowing the vibrator 440 to more flexibly act on the surface of the ton bag 20. In this embodiment, the fixed bracket 422 is slidably connected to the outer wall of the silo 100, and the transverse sliding frame 430 is fixedly connected to the movable bracket 426. Furthermore, the movable bracket 426 rotates relative to the fixed bracket 422. The rotary drive member 424 is a drive motor, and the outer wall of the rotary drive member 424 is fixedly connected to the movable bracket 426. In other embodiments, the rotary drive member 424 can also be a rotary cylinder. Furthermore, a rotating sleeve 4222 is formed at the end of the fixed bracket 422 adjacent to the movable bracket 426. The rotating sleeve 4222 is formed with an adapter hole 4223. The power shaft of the rotary drive member 424 is located within the adapter hole 4223 and is rotatably connected to the rotating sleeve 4222. The movable bracket 426 is fixedly connected to the outer wall of the rotary drive member 424, so that the rotary drive member 424 is mounted and fixed to the movable bracket 426, and the rotary drive member 424 drives the movable bracket 426 to rotate relative to the rotating sleeve 4222. It is understood that in other embodiments, the movable bracket 426 can also be rotatably connected to the fixed bracket 422, so that the relative rotation process of the movable bracket 426 and the fixed bracket 422 is smoother.

[0051] like Figure 3 、 Figure 5 and Figure 6 As shown, further, the outer peripheral wall of the rotating sleeve 4222 is formed with an arcuate rotating area 4224. A first limiting wall 4225 and a second limiting wall 4226 are formed along the outer peripheral wall of the rotating sleeve 4222. The movable bracket 426 rotates relative to the fixed bracket 422 in the arcuate rotating area 4224, causing the movable bracket 426 to rotate relative to the rotating sleeve 4222 between the first limiting wall and the second limiting wall. This allows the movable bracket 426 and the fixed bracket 422 to move relative to each other within a predetermined range. In this embodiment, the end of the movable bracket 426 adjacent to the rotating sleeve 4222 rotates relative to the fixed bracket 422 in the arcuate rotating area 4224. Furthermore, a first stop inclined surface and a second stop inclined surface are provided on both sides of the movable bracket 426; when the movable bracket 426 rotates to the first extreme position relative to the rotating sleeve 4222, the first stop inclined surface abuts against the first limiting wall; when the movable bracket 426 rotates to the second extreme position relative to the rotating sleeve 4222, the second stop inclined surface abuts against the second limiting wall.

[0052] like Figure 6 and Figure 7 As shown, the fixed bracket 422 further includes a connected sliding portion 422a and a fixed bracket body 422b. The sliding portion 422a is slidably connected to the outer wall of the silo 100, and the movable bracket 426 is rotatably connected to the fixed bracket body 422b, thereby rotatably connecting the fixed bracket 422 and the movable bracket 426, and the fixed bracket 422 is slidably connected to the outer wall of the silo 100. In this embodiment, the sliding portion 422a and the fixed bracket body 422b are integrally formed, which ensures a secure connection between the sliding portion 422a and the fixed bracket body 422b and a more compact structure of the fixed bracket 422. In other embodiments, the sliding portion 422a and the fixed bracket body 422b can be formed separately and fixedly connected by welding or gluing. Furthermore, the sliding portion 422a and the fixed bracket body 422b are arranged at a predetermined angle, which allows the movable bracket 426 to have a larger range of motion during rotation relative to the fixed bracket 422, thereby allowing the vibrator 440 to move with the movable bracket 426. Furthermore, the preset angle is 110° to 150°, so that the fixed bracket 422 is tilted on the outer wall of the silo 100, so that the vibrator 440 can better act on the outer wall of the ton bag 20 during the rotation of the movable bracket 426 relative to the fixed bracket 422.

[0053] like Figures 7 to 11 As shown, in one embodiment, the up-down moving driving assembly 410 includes an up-down moving driving member 411 and a moving slide rail 413. Figure 12 , the movable slide rail 413 is installed on the outer wall of the silo 100, the connecting component 420 is slidably connected to the movable slide rail 413, the up and down moving drive member 411 is provided on one of the connecting component 420 or the silo 100, and the up and down moving drive member 411 drives the connecting component 420 to slide relative to the movable slide rail 413, so that the sliding position of the connecting component 420 relative to the movable slide rail 413 can be flexibly adjusted. In this embodiment, the up and down moving drive member 411 is an up and down moving driver. The up and down moving drive member 411 is provided on the connecting component 420. It can be understood that in other embodiments, the up and down moving drive member 411 is not limited to being provided on the connecting component 420. For example, the up and down moving drive member 411 is provided on the outer wall of the silo 100. Further, the end of the fixed bracket 422 away from the movable bracket 426 is slidably connected to the movable slide rail 413.

[0054] like Figure 12 and Figure 13 As shown, further, the movable slide rail 413 is provided with a slide groove 4132, and Figure 5 and Figure 7The connecting assembly 420 is provided with a protruding sliding block 421. The sliding block 421 is located within the slide groove 4132 and is slidably connected to the movable slide rail 413. Furthermore, the inner wall of the slide groove 4132 is provided with a first inclined groove 4132a and a second inclined groove 4132b. The first inclined groove and the second inclined groove are arranged opposite each other. The sliding block 421 is provided with a first sliding inclined surface and a second sliding inclined surface. The first sliding inclined surface is located within the first inclined groove and is slidably connected to the slide groove 4132. The second sliding inclined surface is located within the second inclined groove and is slidably connected to the slide groove 4132. This prevents the sliding block 421 from easily detaching from the slide groove 4132 during sliding, ensuring a secure sliding connection between the sliding block 421 and the slide groove 4132. In this embodiment, the sliding block is provided protruding from the sliding portion, and the slide groove 4132 is a dovetail groove, ensuring that the sliding block 421 is securely slidably connected to the slide groove 4132. In one embodiment, when the ton bag residual full discharge device 10 is working, after the ton bag 20 is inflated, the high-frequency vibration mechanism 400 can move up and down on the movable slide rail 413 to increase the contact range with the ton bag 20, and effectively shake off the powder stuck inside the ton bag 20; at the same time, the air vibration mechanism 500 also starts low-frequency vibration, and regularly vibrates the inner membrane of the ton bag 20 at a low frequency, which facilitates the discharge of powder, effectively saves residual materials, reduces the waste of residual materials, better protects the environment, and effectively reduces the input cost of materials.

[0055] like Figure 5 、 Figure 7 、 Figure 12 and Figure 13 As shown, further, the up and down moving driving member 411 is a gear rack drive structure. In one embodiment, the up and down moving driving member 411 is a drive motor 4111, a gear 4113 and an engagement rack 4115, and the drive motor is installed on the connecting assembly 420. In the present embodiment, the drive motor is installed on the sliding portion, the gear is connected to the power shaft of the drive motor, and the gear is rotationally connected to the sliding portion. Specifically, the gear is rotationally connected to the sliding portion via a rotating shaft. The engagement rack is arranged along the length direction of the movable slide 413, and the gear is meshed with the engagement rack for transmission, so that the up and down moving driving member 411 can drive the connecting assembly 420 to slide relative to the movable slide 413.

[0056] like Figure 5 、 Figure 7 、 Figure 12 and Figure 13 As shown, further, the meshing rack is arranged in the slide groove 4132, making the structure of the movable slide rail 413 more compact, and at the same time making the movable slide rail 413 reliably slidably connected to the connecting assembly 420 when the gear and the meshing rack are meshed and driven. It can be understood that in other embodiments, the up and down moving drive member 411 is not limited to a gear rack drive structure. For example, the up and down moving drive member 411 is a belt drive structure. See also Figure 11Furthermore, gear 4113 includes a first gear 4112 and a second gear 4114. The first gear meshes with the second gear, the first gear being connected to the power shaft of the drive motor, and the second gear being rotatably connected to the sliding portion via a rotating shaft. The second gear meshes with the meshing rack, thereby meshing the gears with the meshing rack. In this embodiment, a cavity 4221 is formed on one side of the sliding portion 422a adjacent to the meshing rack. The drive motor is housed within this cavity. Both the first and second gears are located within this cavity, allowing the vertically movable drive member 411 to be partially contained within the cavity, thereby making the structure of the ton bag residual discharge device more compact.

[0057] Furthermore, the high-frequency vibration mechanism 400 operates for 4 to 6 minutes. After the high-frequency vibration mechanism 400 operates for a predetermined time, the high-frequency vibration mechanism 400 stops and resets. When the high-frequency vibration mechanism 400 operates for 5 minutes, the high-frequency vibration mechanism 400 stops operating, and the vertically movable drive member 411 drives the connecting assembly 420 to slide and reset relative to the silo 100.

[0058] In one embodiment, a support structure is provided on the silo 100 , and the high-frequency vibration mechanism 400 and the clamping device are both fixed on the support structure on the silo 100 .

[0059] like Figure 3 and Figure 14 As shown, the air vibration mechanism 500 further includes a mounting bracket 510, an air flow vibration assembly 520, a connecting pipe 530, and an air filter 540. The mounting bracket 510 is fixedly connected to the outer peripheral wall of the silo 100. The air flow vibration assembly 520 is mounted and connected to the mounting bracket 510. The air outlet end of the air flow vibration assembly 520 is connected to one end of the connecting pipe 530. The other end of the connecting pipe 530 is located in the mounting hole 106 and connected to the silo 100. The air filter 540 is provided on the connecting pipe 530. The air pumped into the connecting pipe 530 by the air flow vibration assembly 520 is filtered by the air filter 540, thereby improving the cleanliness of the air flow input to the air vibration mechanism 500. Furthermore, the mounting bracket 510 is welded to the outer peripheral wall of the silo 100, so that the mounting bracket 510 is fixedly connected to the silo 100. In this embodiment, the airflow vibration assembly 520 includes a cylinder 522, a connecting rod 524 and an airbag body 526. The cylinder is fixedly connected to the mounting bracket 510, the connecting rod is connected to the power output end of the cylinder, and the end of the connecting rod away from the cylinder is fixedly connected to the airbag body. The cylinder drives the connecting rod to telescopic movement, so that the connecting rod drives the airbag body to telescopic movement, so that the cylinder squeezes the gas in the airbag body. The end of the airbag body away from the connecting rod is connected to the connecting tube 530. When the cylinder is working, the connecting rod moves relative to the airbag body, so that the air in the airbag body is pumped into the connecting tube 530.

[0060] like Figure 2 and Figure 3As shown, further, the air intake and exhaust mechanism 300 includes an air intake pipe assembly 310 and an exhaust pipe assembly 320. The air intake pipe assembly 310 and the exhaust pipe assembly 320 are both connected to the inner cavity of the silo 100. The exhaust pipe assembly 320 is provided with a pressure relief valve 322. When the pressure in the silo 100 reaches a predetermined value, the pressure relief valve 322 relieves the pressure in the silo 100 to avoid the problem of the ton bag 20 being filled and exploded. Furthermore, the exhaust pipe assembly 320 includes an exhaust pipe 321, a first filter element 323, and a pressure relief valve 322. The exhaust pipe 321 communicates with the silo 100. The first filter element 323 is located on the exhaust pipe 321, and the pressure relief valve 322 is also located on the exhaust pipe 321. When the pressure within the silo 100 reaches a predetermined value, the pressure relief valve 322 relieves the pressure within the silo 100, preventing the bulk bags 20 from bursting. The first filter element 323 located on the exhaust pipe 321 prevents powder from escaping through the exhaust pipe 321. In this embodiment, the exhaust pipe 321 is tightly connected to the silo 100. Air begins to flow in through the air inlet, inflating the bulk bags 20 to the set value. If the air pressure is too high, the pressure relief valve 322 releases the pressure, preventing the bulk bags 20 from bursting. Specifically, the exhaust pipe 321 is fixed to the outer wall of the silo 100 by screws.

[0061] like Figure 2 and Figure 3 As shown, further, the air inlet pipe assembly 310 includes an air source pumping part (not shown), an air inlet pipe 314 and a second filter element 316. The two ends of the air inlet pipe 314 are respectively connected to the air source pumping part and the silo 100. The air source pumping part is used to fill the air into the air inlet pipe 314. The second filter element 316 is provided on the air inlet pipe 314 to filter the air in the air inlet pipe 314 and reduce the impurities of the powder in the silo 100. In this embodiment, the air inlet pipe 314 is tightly connected to the silo 100. Specifically, the air inlet pipe 314 is fixedly connected to the outer peripheral wall of the silo 100 by screws. Furthermore, the air inlet pipe assembly 310 also includes a pressure regulating valve 318. The pressure regulating valve 318 is electrically connected to the control end of the air source pumping part to adjust the air pressure in the silo 100, thereby improving the ease of use of the ton bag residual full discharge device 10.

[0062] In one embodiment, after inflation is completed, the drive motor drives the movable bracket 426 to drive the vibrator close to the ton bag 20, first running to the top, then vibrating up and down and left and right in sequence, and finally moving to the bottom to vibrate. The vibration frequency is 3000-30000 times / min and starts to vibrate, and the vibration stops after a certain period of time. The air vibration mechanism 500 also starts to vibrate at high frequency, and its air vibration frequency is 300-1000 times / min. The air vibration mechanism 500's intake and exhaust volume each time is 1 / 50-1 / 100 of the ton bag 20. After running for 5 minutes, the high-frequency vibration mechanism 400 stops working, and the drive motor resets the vibrator 440. After the residual material is cleaned up, the exhaust pipe 321 enters the exhaust mode until the exhaust is complete.

[0063] like Figures 1 to 3 As shown, the present application also provides a feeding device 30, including the device 10 for fully emptying the residual ton bag according to any of the above embodiments. In one embodiment, the device 10 for fully emptying the residual ton bag includes a silo 100, a clamping mechanism 200, an air intake and exhaust mechanism 300, and a high-frequency vibration mechanism 400. The silo 100 is formed with a silo opening 102; the clamping mechanism 200 is arranged on the outer wall of the silo 100, and the clamping mechanism 200 is used to clamp the bag opening of the ton bag 20 so that the bag opening is arranged toward the silo opening 102, thereby avoiding the problem of the bag opening shaking relative to the silo opening 102 causing the residual material to be scattered, thereby fixing the bag opening of the ton bag 20 at a position corresponding to the silo opening 102. The air intake and exhaust mechanism 300 is used to inflate the ton bag 20 so that the residual material in the ton bag 20 can be poured out reliably. The high-frequency vibration mechanism 400 is provided on the outer wall of the silo 100 . The high-frequency vibration mechanism 400 is used to vibrate the ton bag 20 after the ton bag 20 is inflated, so that the residual material in the ton bag 20 can reliably slide out of the ton bag 20 .

[0064] The above-mentioned feeding equipment 30 and the silo 100 are formed with a silo opening 102. When the ton bag 20 is transported to the top of the silo opening 102, the clamping mechanism 200 is clamped on the bag opening of the ton bag 20 so that the bag opening is set toward the silo opening 102; the air intake and exhaust mechanism 300 inflates the ton bag 20. Since the high-frequency vibration mechanism 400 vibrates the ton bag 20 after the ton bag 20 is inflated, the residual material in the ton bag 20 can be reliably poured out, which solves the problem of a large amount of residual material in the ton bag 20 after feeding.

[0065] like Figure 1 As shown, the feeding equipment 30 further includes a crane 40, which is used to lift the ton bag 20 to the position corresponding to the clamping mechanism 200 at the silo opening 102. When the crane 40 lifts the ton bag 20 to the silo opening 102, the clamping mechanism 200 clamps the bag opening of the ton bag 20, so that the bag opening is placed toward the silo opening 102.

[0066] In one embodiment, the unloading process of the ton bag residual sufficient unloading device 10 is as follows: first, the ton bag 20 is hoisted to the silo opening 102 using the traveling crane 40, the ton bag 20 is fixed to the wound of the silo 100, and the bag opening is clamped using the clamping device; secondly, after most of the materials are put in, the butterfly valve is closed; then the air inlet of the air intake and exhaust mechanism 300 starts to intake air, and the entire ton bag 20 is inflated to the set value. If the air pressure is too high, the pressure relief valve 322 will release the pressure to avoid the ton bag 20 from bursting; then, after the inflation is completed, the high-frequency vibration The drive motor of the connecting assembly 420 of the dynamic mechanism 400 drives the movable bracket 426, which propels the vibrator against the ton bag 20. The vibrator first moves to the top, then vibrates in a sequence of up, down, left, and right directions, finally moving to the bottom and vibrating at a frequency of 3,000 to 30,000 vibrations per minute. The vibrations cease after a certain period of time. The air vibrator 500 also begins vibrating when the high-frequency vibrator 400 is in the high-frequency mode, with a frequency of 300 to 1,000 vibrations per minute. The air vibrator 500's intake and exhaust volume is 1 / 100 to 1 / 50 of the ton bag 20's volume. After the air vibrator 500 has operated for five minutes, the high-frequency vibrator 400 stops, and the drive motor resets the vibrator 440. Once the residual material is removed, the exhaust pipe 321 enters exhaust mode until exhaust is complete. Finally, the butterfly valve opens, the residual material is delivered, and the compactor opens, allowing the ton bag 20 to be removed, completing a single cycle. The ton bag residual sufficient unloading device 10 of the present application can effectively reduce material waste and increase feeding efficiency.

[0067] Compared with the prior art, the present invention has at least the following advantages:

[0068] The above-mentioned ton bag residual sufficient unloading device 10, the silo 100 is formed with a silo opening 102, when the ton bag 20 is transported to the top of the silo opening 102, the clamping mechanism 200 is clamped on the bag opening of the ton bag 20 to set the bag opening toward the silo opening 102; the air intake and exhaust mechanism 300 inflates the ton bag 20, and the high-frequency vibration mechanism 400 vibrates the ton bag 20 after the ton bag 20 is inflated, so that the residual material in the ton bag 20 can be reliably poured out, which solves the problem of a large amount of residual material in the ton bag 20 after feeding.

[0069] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
