[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figures 1 - 7 , the present invention provides the following two technical solutions:

[0025] The first implementation method: An intelligent bulk loading machine includes an upper housing 1, a middle housing 2, and a lower housing 3. The bottom of the upper housing 1 is connected to an outer cylinder 7. A first telescopic pipe 4 is connected between the outer cylinder 7 and the middle housing 2. A second telescopic pipe 5 is connected between the middle housing 2 and the lower housing 3. Guide pipes 6 are evenly arranged vertically in the first telescopic pipe 4. The middle position at the bottom of the upper housing 1 extends into the top guide pipe 6, and adjacent guide pipes 6 cooperate with each other for guiding materials. The bottom of the bottom guide pipe 6 extends into the middle housing 2. In this way, the materials can gradually slide down from top to bottom. Both the first telescopic pipe 4 and the second telescopic pipe 5 are composed of steel rings and canvas, and the guide pipes 6 are arranged on the steel rings;

[0026] An elevating drive mechanism connected to the middle housing 2 is arranged on the upper housing 1, and a telescopic position detection component is arranged on the elevating drive mechanism. A feeding position detection mechanism is arranged on the middle housing 2. A dust removal mechanism and a pulse back-blowing mechanism are arranged on the outer cylinder 7.

[0027] The elevating drive mechanism includes a box body 8 arranged on the upper housing 1. Guide wheels 9 are arranged on the front and rear sides of the upper housing 1. A steel wire rope 10 is wound around the guide wheels 9. The guide wheels 9 are used to guide the steel wire rope 10. The bottom of the steel wire rope 10 is connected to the middle housing 2. Among them, a guide ring can be arranged on the first telescopic pipe 4, and the steel wire rope 10 can pass through the guide ring, so as to prevent the steel wire rope 10 from disengaging. The steel wire rope 10 is connected to a hoisting drum 11, and the hoisting drum 11 is arranged on the output shaft of a reduction motor 12. The reduction motor 12 is arranged on the box body 8. The reduction motor 12 drives the hoisting drum 11 to rotate, which can drive the steel wire rope 10 to wind and unwind. In-place detection devices 17 for the steel wire rope 10 to pass through are arranged at the front and rear ends on the left side of the box body 8. A proximity switch 18 is also arranged on the box body 8. When tightened, it can drive the in-place detection device 17 to be horizontal, and the proximity switch 18 cannot detect it. After the elevating drive mechanism drives the lower housing 3 to be connected to the tanker opening, the steel wire rope 10 can continue to descend. At this time, the steel wire rope 10 is no longer tightened, and then the in-place detection device 17 can droop due to the action of gravity, and then is detected by the proximity switch 18 and stops descending, which is convenient for automatically controlling the steel wire rope 10 to stop moving.

[0028] The telescopic position detection component includes a multi-functional limiter 16 provided on the box body 8. A driving sprocket 13 is provided on the output shaft of the reduction motor 12. A chain 14 is provided on the driving sprocket 13. The chain 14 is in transmission connection with a driven sprocket 15, and the driven sprocket 15 is provided on a rotating shaft, and the rotating shaft is connected to the multi-functional limiter 16. The rotation of the rotating shaft is increased through the driving sprocket 13, the chain 14 and the driven sprocket 15. The large number of rotation turns makes the detection of the multi-functional limiter 16 more accurate. By adjusting the multi-functional limiter 16, the upper and lower limit positions of the telescopic movement can be adjusted. After adjustment, the upper and lower limit positions during the telescopic movement can be detected, without the need for manual observation. When the limit height is reached, the multi-functional limiter 16 can detect it, so that the lifting and lowering drive mechanism can be automatically stopped from lifting or lowering, thus ensuring the safe operation of the lifting and lowering drive mechanism and preventing dangerous situations such as overwinding and overloading from occurring.

[0029] The feeding position detection mechanism includes a protective cover 19 provided at the bottom of the middle housing 2. A rotary vane level gauge 20 is provided at the bottom of the protective cover 19. A threading pipe can also be provided. The protective cover 19 prevents materials from falling onto the rotary vane level gauge 20, so that the materials are discharged between the lower housing 3 and the protective cover 19. A rubber layer 21 is provided on the outer side of the lower housing 3, which is provided on the conical outer surface of the lower housing 3 and is cast NBR rubber, which can have good contact with the tanker feeding port and reduce material dust.

[0030] The dust removal mechanism includes a filter cartridge 22 provided on the upper housing 1. The bottom of the filter cartridge 22 is located inside the outer cylinder 7. The material of the filter cartridge 22 is standard polyester, with film-coated anti-static property. An observation door 27 is provided on the outer cylinder 7. The top of the filter cartridge 22 is located inside the upper housing 1, and a fan 23 is provided on the upper housing 1. An installation pipe 28 is provided at the output end of the fan 23. A fixing frame 29 is provided at the top of the installation pipe 28. Baffles 30 can be detachably connected to the front and rear sides of the fixing frame 29. A filter plate 32 penetrating the top of the installation pipe 28 is provided on the inner wall of the fixing frame 29. The top of the filter plate 32 is connected to an electric telescopic rod 31 provided on the fixing frame 29. The filter plate 32 is provided to prevent external dust from entering the impeller of the fan 23 through the output end of the fan 23 when the fan 23 is not in use, which affects the rotation of the impeller. When the fan 23 is in use, the electric telescopic rod 31 can drive the filter plate 32 to move upward, so that the surface dust can be scraped off and then discharged by the wind force of the fan 23, and it will not block the installation pipe 28. When forgetting to drive the filter plate 32 to move upward, ventilation can also be temporarily carried out through the filter plate 32 to avoid the situation of damaging the fan 23.

[0031] The second implementation mode is mainly different from the first implementation mode in that: the pulse backwashing mechanism includes an air storage cylinder 24 arranged on the outer cylinder 7, a filter pressure reducing valve 25 and an electromagnetic pulse valve 26 are arranged on the air storage cylinder 24, the electromagnetic pulse valve 26 is communicated with a backwashing pipe located above the filter cartridge 22, the filter pressure reducing valve 25 supplies filtered and decompressed air into the air storage cylinder 24, and each electromagnetic pulse valve 26 is opened at intervals for a certain time, so that the air in the air storage cylinder 24 enters the filter cartridge 22 through the backwashing pipe, blows off the materials on the outer surface of the filter cartridge 22 and loads them with the materials, so as to achieve the purpose of cleaning the filter cartridge 22.

[0032] It also includes a control cabinet, which is responsible for the operation and stop of each mechanism.

[0033] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0034] During use, the upper shell 1 contains flange bolts and is connected to the upstream feeding pipeline. After the lifting drive mechanism releases the steel wire rope 10 and connects the lower shell 3 to the tanker opening, the steel wire rope 10 continues to descend. Due to gravity, the in-place detection device 17 sags and stops descending after being detected by the proximity switch 18. Then the fan 23 starts to work, and the dust materials during loading are adsorbed on the surface of the filter cartridge 22 to ensure that there is no dust when the materials enter the tanker, achieving the purpose of dust removal. And the air storage cylinder 24 intakes air, and the upstream feeding control valve is opened to start loading. During loading, the rotary vane level gauge 20 rotates continuously. When the materials contact the rotary vane level gauge 20, it stops rotating, thereby indicating that the materials are full. When the rotary vane level gauge 20 detects that the materials are full, the upstream feeding control valve is closed, the fan 23 is turned off and the air intake of the air storage cylinder 24 is stopped, and the lifting drive mechanism drives the lower shell 3 to rise to the initial position, and the loading is completed.
