[0027] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] like Figures 1-6 As shown, the automatic clearing machine provided in this embodiment includes...

[0029] A triangular anti-torsion protection frame structure 1 is fixedly sleeved on the telescopic cantilever 2. The triangular anti-torsion protection frame structure 1 is used to resist torsion and protect the telescopic cantilever 2. The telescopic cantilever 2 can easily achieve the free extension of the cutting head structure 3 through its own telescopic characteristics, so that the cutting head structure 3 can always have a suitable working distance during operation. Here, the telescopic cantilever 2 refers to the existing telescopic structure device, so the internal working principle of the telescopic cantilever 2 is the existing technology.

[0030] The cutting head structure 3 is vertically installed at the end of the telescopic cantilever 2. The cutting head structure 3 is used for intelligent cleaning of the deposits attached to the inner wall of the silo.

[0031] The control frame supports the rotating platform structure 4, which is installed above the head end of the telescopic cantilever 2. The control frame supports the rotating platform structure 4 is used to fix and support the telescopic cantilever 2 and control the working status of the telescopic cantilever 2 and the cutting head structure 3 during operation.

[0032] The telescopic cantilever 2 can be protected against torsion by the triangle-like anti-torsion protection frame structure 1, and the torsion force generated by the rotating chain hammer can be effectively shared, so that the telescopic cantilever 2 will not be subjected to a large torsion force and a shaking force due to the rotation of the chain hammer, thereby preventing the internal structure of the telescopic cantilever 2 from being damaged and affecting the telescopic function of the telescopic cantilever 2.

[0033] Further, as shown in Figure 2 and Figure 4 , the telescopic cantilever 2 comprises a fixed sleeve main pipe rod 5, a first telescopic sub-pipe rod 6 which can automatically slide and contract in the fixed sleeve main pipe rod 5, a second telescopic sub-pipe rod 7 which can automatically slide and contract in the first telescopic sub-pipe rod 6, a third telescopic sub-pipe rod 8 which can automatically slide and contract in the second telescopic sub-pipe rod 7, and a limiting rope passing buckle 9 installed at the end of the third telescopic sub-pipe rod 8. The fixed sleeve main pipe rod 5, the first telescopic sub-pipe rod 6, the second telescopic sub-pipe rod 7, and the third telescopic sub-pipe rod 8 cooperate to facilitate the telescopic function of the telescopic cantilever 2, and the limiting rope passing buckle 9 facilitates the anti-disengagement and limiting of the steel cable hung and installed on the cutting head structure 3 below the end of the telescopic cantilever 2.

[0034] Further, as shown in Figure 2 and Figure 3 , the triangle-like anti-torsion protection frame structure 1 comprises a mounting sleeve 10 sleeved on the fixed sleeve main pipe rod 5, three support anti-torque sleeves 11 arranged on the two sides and the lower surface of the mounting sleeve 10, a first torsion force sharing limiting pipe rod 12 slidingly and clampingly arranged in the support anti-torque sleeve 11, a second torsion force sharing limiting pipe rod 13 slidingly and clampingly arranged in the first torsion force sharing limiting pipe rod 12, and a third torsion force sharing limiting pipe rod 14 slidingly and clampingly arranged in the second torsion force sharing limiting pipe rod 13. The mounting sleeve 10 facilitates sleeving the triangle-like anti-torsion protection frame structure 1 on the fixed sleeve main pipe rod 5, the support anti-torque sleeve 11 facilitates limiting and anti-torque storage of the first torsion force sharing limiting pipe rod 12, the first torsion force sharing limiting pipe rod 12 facilitates limiting and anti-torque storage of the second torsion force sharing limiting pipe rod 13, and simultaneously facilitates anti-torsion protection of the first telescopic sub-pipe rod 6, the second torsion force sharing limiting pipe rod 13 facilitates limiting and anti-torque storage of the third torsion force sharing limiting pipe rod 14, and simultaneously facilitates anti-torsion protection of the second telescopic sub-pipe rod 7, and the third torsion force sharing limiting pipe rod 14 facilitates anti-torsion protection of the third telescopic sub-pipe rod 8.

[0035] Further, as shown in Figure 2As shown, the outer end surface of the first telescopic sub-tube rod 6 is connected with the outer end surface of the three first torsion force sharing limiting tube rods 12 through the first triangular fixing block 15, the outer end surface of the second telescopic sub-tube rod 7 is connected with the outer end surface of the three second torsion force sharing limiting tube rods 13 through the second triangular fixing block 16, and the outer end surface of the third telescopic sub-tube rod 8 is connected with the outer end surface of the three third torsion force sharing limiting tube rods 14 through the third triangular fixing block 17. The first triangular fixing block 15 cooperates with the three first torsion force sharing limiting tube rods 12 to facilitate the fixing of the three first torsion force sharing limiting tube rods 12 on the outer end surface of the first telescopic sub-tube rod 6. The second triangular fixing block 16 cooperates with the three second torsion force sharing limiting tube rods 13 to facilitate the fixing of the three second torsion force sharing limiting tube rods 13 on the outer end surface of the second telescopic sub-tube rod 7. The third triangular fixing block 17 cooperates with the three third torsion force sharing limiting tube rods 14 to facilitate the fixing of the three third torsion force sharing limiting tube rods 14 on the outer end surface of the third telescopic sub-tube rod 8. This makes the triangular anti-torsion protection frame structure 1 form a triangular column-like support frame, which can effectively resist the torsion force transmitted from the cutting head structure 3 during operation, thereby better protecting the telescopic cantilever 2.

[0036] Further, as shown in Figure 6 The cutting head structure 3 includes a protective shell 18, a mounting connecting block 19 arranged at the top end of the protective shell 18, a first drive motor 20 arranged at the bottom of the protective shell 18, a connecting fixed turntable 21 arranged at the bottom end of the output shaft of the first drive motor 20 penetrating the bottom of the protective shell 18, and two swinging chain hammers 22 symmetrically mounted on the connecting fixed turntable 21.

The mounting connecting block 19 facilitates the smooth installation of the terminal end of the steel cable on the cutting head structure 3. The first drive motor 20 facilitates the provision of driving force for the rotating operation of the connecting fixed turntable 21. The connecting fixed turntable 21 facilitates the connection of the two swinging chain hammers 22 to the output end of the first drive motor 20. The two swinging chain hammers 22 facilitate the crushing and cleaning of the attached objects attached to the inner wall of the bin under the driving of the first drive motor 20.

[0037] Further, as shown in Figure 5As shown, the control net frame support rotating platform structure 4 comprises a support fixed frame 23 hinged at the first end of the fixed sleeve main pipe rod 5, a hydraulic cylinder 24 hinged between the support fixed frame 23 and the fixed sleeve main pipe rod 5, a limiting pulley 33 arranged on the support fixed frame 23, a support frame plate 25 arranged above the support fixed frame 23, a rotating assembly 26 installed on the support frame plate 25, a winch assembly 27 installed beside the rotating assembly 26, and a control operation module 35 arranged on the support frame plate 25. The support fixed frame 23 facilitates the connection of the telescopic cantilever 2 and the control net frame support rotating platform structure 4 together. The hydraulic cylinder 24 facilitates the telescopic adjustment of the telescopic cantilever 2 and the support fixed frame 23. The hydraulic cylinder 24 can adjust the included angle between the telescopic cantilever 2 and the hydraulic cylinder 24 through its telescopic property, so that the telescopic cantilever 2 is always in the most suitable working position during operation. The limiting pulley 33 facilitates the turning and limiting of the steel cable connected to the suspended cutting head structure 3. The support frame plate 25 facilitates the fixing and supporting of the rotating assembly 26, the winch assembly 27 and the control operation module 35, and facilitates the fixing and installation of the control net frame support rotating platform structure 4 above the opening of the silo to be cleaned. The rotating assembly 26 facilitates the overall rotation of the support fixed frame 23, the telescopic cantilever 2 and the cutting head structure 3. The winch assembly 27 facilitates the lifting of the cutting head structure 3 in the silo in cooperation with the steel cable connected to the cutting head structure 3. The control operation module 35 facilitates the receipt of instructions from the operator and controls the overall operation of the device according to the instructions. The control operation module 35 here refers to the existing device, so the operation principle of the control operation module 35 is the prior art.

[0038] Further, as shown in Figure 5 The rotating assembly 26 comprises a clamping rotating block gear 28 arranged at the top end of the support fixed frame 23, a second driving motor 29 installed on the support frame plate 25, and a driving gear 30 arranged at the output end of the second driving motor 29. The driving gear 30 is matched with the clamping rotating block gear 28. The support fixed frame 23 is clamped and fixed on the support frame plate 25 through the clamping rotating block gear 28. The clamping rotating block gear 28, the driving gear 30 and the second driving motor 29 are matched to facilitate the slow rotation of the support fixed frame 23 on the support frame plate 25.

[0039] Further, as shown in Figure 5 The winch assembly 27 comprises a support frame 31, a digital manual winch 32 arranged in the support frame 31, and a digital hydraulic winch 34 arranged at the top end of the support frame 31. The support frame 31 facilitates the fixing and supporting of the digital manual winch 32 and the digital hydraulic winch 34. The digital hydraulic winch 34 facilitates the approximate adjustment of the lifting of the cutting head structure 3. The digital manual winch 32 facilitates the manual fine adjustment of the lifting of the cutting head structure 3 in cooperation with the digital hydraulic winch 34.

[0040] As Figures 1-6 shown, the principle of the automatic silo cleaning machine provided by the embodiment is as follows: the device should first take out the steel cable when working, then fix the first end of the steel cable to the digital hydraulic winch 34, then pass the other end of the steel cable through a limiting pulley 33, then slide it through the fixed connection in the mounting connecting block 19, and finally pass the end of the steel cable through another limiting pulley 33, at which time the end of the steel cable can be fixed to the digital manual winch 32, and then the worker can use the detection scanner to detect the attachments inside the silo in advance, and then transmit the specific analysis information to the control computer;

[0041] At this time, the device can be transported to the upper opening of the silo where work is needed, at which time the support fixing frame 23, the triangular anti-twist protection frame structure 1, the telescopic cantilever 2, and the cutting head structure 3 are all in the silo, only the upper opening of the control net support rotating platform structure 4, then the support frame plate 25 is fixed and installed at the upper opening of the silo, then the control computer is connected with the control operation module 35, then the operation command and the information detected in advance are transmitted to the control operation module 35, and then the control operation module 35 will clean the inner wall of the silo according to the operation command and the information detected in advance;

[0042] At this time, the second drive motor 29 starts working, and the second drive motor 29 working will take the connected fixed turntable 21 to rotate quickly, then the control operation module 35 will control the hydraulic cylinder 24 to stretch moderately, and at the same time the control operation module 35 will control the telescopic cantilever 2 to stretch moderately, at this time the rotating fixed turntable 21 will facilitate the two swinging chain hammers 22 to break and clean the attachments attached to the inner wall of the silo, at this time the control operation module 35 will continue to control the telescopic cantilever 2 and the hydraulic cylinder 24 to stretch or contract moderately according to the information detected in advance, and at the same time the second drive motor 29 will also drive the drive gear 30 to rotate, then the rotating drive gear 30 will drive the clamping rotating block gear 28 to rotate, at this time the support fixing frame 23, the telescopic cantilever 2, and the cutting head structure 3 can rotate, which makes the two rotating swinging chain hammers 22 can break and clean the attachments attached to any place of the inner wall of the silo, until the attachments attached to the inner wall of the silo are completely cleaned, then the work can be stopped, and then the device can be taken out;

[0043] When the control operation module 35 continues to control the telescopic cantilever 2 to stretch or shrink moderately according to the information detected in advance, the triangular anti-torsion protection frame structure 1 also stretches with the stretching of the telescopic cantilever 2, and the triangular anti-torsion protection frame structure 1 also shrinks with the shrinking of the telescopic cantilever 2. When the two rotating swinging hammers 22 produce a certain torsional force and a shaking force when breaking the attached objects, the torsional force and the shaking force are transmitted to the third telescopic sub-pole 8 through the limiting rope buckle 9, which makes the telescopic cantilever 2 continuously receive the torsional force and the shaking force. At this time, the triangular anti-torsion protection frame structure 1 continuously protects the telescopic cantilever 2, and the three third torsional force sharing limiting poles 14 are convenient for the anti-torsion protection of the third telescopic sub-pole 8, the three second torsional force sharing limiting poles 13 are convenient for the anti-torsion protection of the second telescopic sub-pole 7, and the three first torsional force sharing limiting poles 12 are convenient for the anti-torsion protection of the first telescopic sub-pole 6. At this time, the torsional force and the shaking force received by the telescopic cantilever 2 are shared by the structures in the triangular anti-torsion protection frame structure 1, and the triangular anti-torsion protection frame structure 1 forms a triangular column-like support frame as a whole, so as to effectively resist the torsional force and the shaking force transmitted from the cutting head structure 3 during operation, thereby better protecting the telescopic cantilever 2, so as to prevent the internal structure of the telescopic cantilever 2 from being damaged, thereby preventing the telescopic function of the telescopic cantilever 2 from being affected.
