It is mainly used to solve the problem of blockage caused by materials forming clumps due to moisture, compression, etc. during storage, which adhere to the silo walls or accumulate at the bottom of the silo. Current unblocking operations still have significant limitations. When a silo is blocked, existing unblocking methods often fail to achieve the desired results. To ensure thorough cleaning, it is necessary to send personnel inside the silo for manual operation. However, the internal environment of a silo is complex, with safety hazards such as material collapse and accumulation of harmful gases. Personnel entering the silo are highly susceptible to accidents, seriously threatening their lives and significantly increasing the risks and difficulty of the operation.

[0003] Therefore, this utility model proposes a pneumatic rotary unblocking device to solve the above problems. Utility Model Content

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Reference Figures 1-3 As shown, a pneumatic rotary unblocking device includes: The frame body 110 has two sets of roller structures 120 symmetrically arranged at its bottom end; The position adjustment component includes a first drive arm 310, a second drive arm 320, and a third drive arm 330 that are hinged together in sequence. A base plate 360 ​​for mounting is arranged between the first drive arm 310 and the frame 110 so that the unblocking component is mounted on the frame 110 and its position is adjusted as the lower part of the frame 110 moves. A longitudinal adjustment structure 340 is arranged between the first drive arm 310 and the second drive arm 320, and a lateral adjustment structure 350 is arranged between the second drive arm 320 and the third drive arm 330. The longitudinal adjustment structure 340 drives the first drive arm 310 and the second drive arm 320 to open and close to adjust the height of the second hinged arm, and the lateral adjustment structure 350 drives the third drive arm 330 to rotate laterally at the hinge point of the second drive arm 320 and the third drive arm 330.

[0022] Furthermore, the first drive arm 310 and the second drive arm 320 are located in the same vertical plane. The second drive arm 320 can rotate along the hinge point of the first drive arm 310 and the second drive arm 320 located in the vertical plane to adjust the angle between the first drive arm 310 and the second drive arm 320. When the pneumatic unblocking device is located at the top of the hopper, the first drive arm 310 and the second drive arm 320 extend from the top of the hopper into the inner cavity of the hopper. The longitudinal adjustment structure 340 adjusts the angle between the first drive arm 310 and the second drive arm 320, thereby adjusting the height of the second drive arm 320 in the hopper.

[0023] Furthermore, the longitudinal adjustment structure 340 includes a first connecting seat 341 fixed on the first drive arm 310, a second connecting seat 342 arranged on the second drive arm 320, and a first cylinder 343 disposed between the first connecting seat 341 and the second connecting seat 342. The two ends of the first cylinder 343 are rotatably connected to the first connecting seat 341 and the second connecting seat 342, respectively.

[0024] Furthermore, the third drive arm 330 and the second drive arm 320 are located in the same transverse plane, which is perpendicular to the vertical plane where the first drive arm 310 and the second drive arm 320 are located. The third drive arm 330 can rotate in the transverse plane along the hinge point of the second drive arm 320 and the third drive arm 330. The transverse adjustment structure 350 includes a third connecting seat 351 fixed on the second drive arm 320, a fourth connecting seat 352 arranged on the third drive arm 330, and a second cylinder 353 disposed between the third connecting seat 351 and the fourth connecting seat 352. The two ends of the second cylinder 353 are rotatably connected to the third connecting seat 351 and the fourth connecting seat 352, respectively.

[0025] The unblocking component includes a manual line-laying structure 210, a connecting rope 220, and a rotary crushing structure 230 arranged on the frame 110. The manual line-laying structure 210 is connected to the rotary crushing structure 230 through the connecting rope 220. The rotary crushing structure 230 includes an air pump 231 connected to the rope and a crushing unit 232 connected to the surface of the air pump 231.

[0026] Furthermore, the surfaces of the first drive arm 310, the second drive arm 320, and the third drive arm 330 are arranged with at least three sets of lead wire loops 240. The connecting rope 220 passes through the lead wire loops 240. The first drive arm 310, the second drive arm 320, and the third drive arm 330 are all arranged with at least one set of lead wire loops 240. This allows the connecting rope 220 to adjust with the movements of the first drive arm 310, the second drive arm 320, and the third drive arm 330. At the same time, the lead wire loops 240 prevent the connecting rope 220 from becoming entangled or knotted between the first drive arm 310, the second drive arm 320, and the third drive arm 330 during their movements. This ensures that the connecting rope 220 can move smoothly with the adjustment of the drive arm, and that the rotary crushing structure 230 can accurately reach the unblocking position and stably perform its unblocking function.

[0027] Furthermore, the manual wire release structure 210 includes a winding drum 211, extension rods 213 arranged at both ends of the winding drum 211, and a support base 214 sleeved on the extension rods 213. The support base 214 is assembled on the frame body 110. The end of the extension rod 213 located at one end, away from the winding drum 211, is connected to a crank handle 212. The crank handle 212 drives the winding drum 211 and the extension rods 213 at both ends to rotate together to wind or release the connecting rope 220.

[0028] The output end of the air pump 231 is connected to the connecting rope 220. The crusher unit 232 is installed on the end of the air pump 231 away from the connecting rope 220. The crusher unit 232 includes a connecting column mounted on the air pump 231 and a crushing blade mounted on the connecting column. When the air pump 231 is started, the air pump 231 drives the connecting rope 220 to rotate, thereby causing the crusher unit 232 mounted on the air pump 231 to rotate synchronously, thereby breaking off the clumps on the inner wall of the hopper to achieve the purpose of cleaning and unblocking.

[0029] Working Principle: For circular silos, the air pump 231 of the pneumatic rotary unblocking device is lowered to the slag discharge port. The air pump 231 is then turned on to drive the connecting rope 220 to rotate, which in turn drives the crusher unit 232 mounted on the air pump 231 to rotate synchronously. The high-speed rotating crushing blades break down the clumps on the inner wall of the silo. Simultaneously, the unblocking component, using a position adjustment mechanism, performs the unblocking operation from the bottom of the silo upwards. The first drive arm 310 and the second drive arm 320 are in the same vertical plane. The angle is adjusted by the longitudinal adjustment structure 340, changing the height of the second drive arm 320 within the silo, allowing the unblocking component to operate gradually from the bottom upwards. Simultaneously, the manual line-laying structure 210 in the unblocking component controls the lowering length of the connecting rope 220. Combined with the guide ring 240 on the surface of the drive arm, this allows the rotating crushing structure 230 to precisely reach the bottom where cleaning is needed, driving the connecting rope 220 and the crusher unit 232 mounted on the air pump 231 to rotate. The high-speed rotating crushing blades then clear a channel through the silo wall. After clearing the first channel, the position of the pneumatic rotary unblocking device is reversed, causing the unblocking component to clear the other channel at a 90° angle from the first channel. The blockage between the two channels will collapse due to loss of support, and at the same time, the crusher unit 232 impacts the hopper wall to provide the collapse force for the blockage, thereby achieving automatic unblocking.

[0030] If the blockage does not fall off automatically, the third drive arm 330 is rotated in a horizontal plane perpendicular to the vertical plane by means of the lateral adjustment structure 350, changing the position of the crusher unit 232. Following the above operation method, the third channel is cleared between the first and second channels to shorten the distance between the channels and increase the destructive effect on the blockage until the blockage is cleared.

[0031] For square silos, by changing the position of the pneumatic rotary unblocking device and coordinating the multi-dimensional adjustment capabilities of the position adjustment components, the crusher unit 232 is guided to a corner position to begin unblocking. The blockage at the corner of the square silo experiences relatively concentrated force, making it easier for the blockage to dislodge and improving unblocking efficiency. Throughout the process, staff outside the silo manipulated positioning and unblocking components to precisely and efficiently clear blockages from the silo without entering, ensuring operational safety.
