[0003] However, the conventional method of installing a fully sealed protective cover on a screw conveying feeding device has the following problems: 1. The fully sealed protective cover on the existing screw conveying device is generally fixed by welding or by a plurality of bolts. The above installation method is not only time-consuming and labor-intensive, but also inefficient, and the disassembly operation is also cumbersome and difficult, which leads to low overall operating efficiency of the conveying device; 2. The length of the existing fully sealed protective cover usually needs to be customized according to the length of the corresponding screw conveying device, which not only leads to high overall cost, poor versatility and flexibility of the sealing cover, but also requires the sealing cover to be disassembled as a whole when inspecting a specific section of the screw conveying device, which not only increases the overall workload and labor cost of the operators, but also leads to low overall operation and maintenance efficiency of the conveying device; 3.

[0035] Please refer to Figure 3 and Figure 4 , the blowing component 32 includes laterally communicating grooves 321 that are symmetrically opened up and down and penetrate through front and back on the vertical sections of the sealing cover 31 that are symmetrically arranged left and right. Two groups of blowing ports 322 that are symmetrically opened up and down and communicate with the corresponding laterally communicating grooves 321 are symmetrically opened on the inner surface of the vertical section of the sealing cover 31. Each group consists of front and back symmetrically arranged blowing ports 322. Upper communicating grooves 323 that penetrate through front and back are symmetrically opened on the horizontal section of the sealing cover 31.

Each group consists of front and back symmetrically arranged blowing ports 324.

[0036] Please refer to Figure 3 , Figure 4 and Figure 5 , the sealing component 33 includes sliding rods 331 that are symmetrically arranged front and back through supports on the inner surface of the corresponding vertical sections of the sealing cover 31. At one end of the symmetrically arranged sliding rods 331 that are far from the center of the horizontal section of the corresponding sealing cover 31, a U-shaped frame 332 with an open bottom is fixedly arranged together.

[0037] Please refer to Figure 3 and Figure 5 , the driving component 34 includes driving plates 341 that are symmetrically arranged front and back at the center below the horizontal section of the sealing cover 31. Oblique straight grooves 342 that are slidably connected to the corresponding driven shafts 335 are opened on the driving plates 341. Slide rods 343 that slide through the corresponding vertical sections of the sealing cover 31 left and right are symmetrically fixed on the left side of the front driving plate 341 and the right side of the rear driving plate 341. At one end of the symmetrically arranged slide rods 343 that are far from the corresponding driving plates 341, a connecting plate 1 is fixedly arranged together.

[0038] When multiple sealing covers 31 are evenly and closely mounted on the upper side of the conveying frame 1, each connecting plate 1 and its corresponding sliding rod 2 343 are synchronously pulled away from the corresponding driving plate 341, and the sliding rod 2 343 drives the corresponding driving plate 341 to move synchronously, and the driving plate 341 then slides with the corresponding driven shaft 335 through the oblique straight groove 342, driving the corresponding U-shaped frame 332 to move away from the center of the horizontal section of the corresponding sealing cover 31, that is, the U-shaped frame 332 and the sealing pad 333 symmetrically moved in opposite directions synchronously. Movement, that is, the front-to-back adjacent U-shaped frames 332 and the sealing pads 333 in the two front-to-back adjacent sealing covers 31 move synchronously toward each other until the driving plate 341 moves to the maximum distance. At this time, the front-to-back adjacent sealing pads 333 are tightly fitted and sealed, so that the joints between the two front-to-back adjacent sealing covers 31 are stably sealed by the front-to-back adjacent sealing pads 333 and the U-shaped frames 332, and at the same time, the inner surfaces of the corresponding sealing covers 31 are stably covered by the filter cloths 334. At this time, the filter cloths 334 are not yet completely tightened.

[0039] See also Figure 1 and Figure 3 The quick-install mechanism 4 includes a plurality of receiving components 41 that are evenly arranged on the conveying frame 1 and correspond to the sealing covers 31 one by one. The sealing cover 31 is provided with a quick-install component 42.

[0040] See also Figure 3 , Figure 6 and Figure 7 The receiving component 41 includes a positioning plate 411 which is symmetrically fixed on the conveying frame 1. A plurality of vertically penetrating mounting holes are evenly arranged on the positioning plate 411. A clamping sleeve 412 is installed in the mounting hole. A vertically penetrating clamping groove 413 is arranged in the clamping sleeve 412. The clamping groove 413 consists of small through grooves and large through grooves distributed vertically.

[0041] See also Figure 3 , Figure 6 and Figure 7 The quick-install component 42 includes an alignment plate 421 that is symmetrically fixed on the sealing cover 31. The alignment plate 421 is evenly provided with a plurality of mounting holes 2 that penetrate up and down and correspond to the mounting holes one by one. An elastic sleeve 422 is installed in the mounting hole 2. The upper ends of the elastic sleeves 422 that are evenly distributed front and back are fixedly connected by a connecting plate 2. The lower end of the elastic sleeve 422 is evenly provided with a plurality of movable grooves that penetrate inside and outside in a circumferential direction. Balls 423 are movably provided in the movable grooves. A pressing column 424 that moves up and down is elastically slidably provided in the elastic sleeve 422. A yielding groove 425 that is pressed and matched with the ball 423 is provided at the lower end of the pressing column 424. The upper ends of the pressing columns 424 that are evenly distributed front and back are fixedly connected by a connecting plate 3.

[0042] When the sealing cover 31 is to be installed on the corresponding positioning plate 411, the lower end of each elastic sleeve 422 is first inserted into the corresponding card connection groove 413, and then the corresponding pressing columns 424 are synchronously moved downward along the elastic sleeve 422 by pressing the connecting plate 3 downward, and the upper side of the yield groove 425 at the lower end of each pressing column 424 is aligned with the corresponding ball 423, and the ball 423 in the movable groove is squeezed by the small through groove at the upper end of the corresponding card connection groove 413 and then received into the yield groove 425, and the lower end of each elastic sleeve 422 is then completely inserted into the corresponding card connection groove 413, and the ball 423 also enters the card connection groove synchronously. The connecting plate 3 is then released again, and under the elastic action of the elastic sleeve 422, each pressing column 424 moves upward and resets, and through the pressure-moving cooperation with the yielding groove 425 and the ball 423, the ball 423 is stably squeezed into the corresponding movable groove again and stably stuck in the connecting section between the large through groove and the small through groove, so that the elastic sleeve 422 and the corresponding clamping sleeve 412 are stably positioned and installed, and then the sealing cover 31 is quickly and stably installed on the corresponding positioning plate 411. The above-mentioned operation method can realize the rapid disassembly and assembly of the sealing cover 31, thereby improving the overall disassembly and assembly efficiency of the sealing cover 31.

[0043] See also Figure 1 and Figure 3 The fastening mechanism 5 includes a fastening assembly 51 arranged on the sealing cover 31, and a docking assembly 52 is arranged on the fastening assembly 51.

[0044] See also Figure 3 and Figure 6 The fastening assembly 51 includes two groups of guide rods 511 symmetrically fixed on the sealing cover 31, each group is composed of front-to-back symmetrical guide rods 511, and a sliding plate 512 that moves left and right is slidably arranged on the front-to-back symmetrical guide rods 511. The upper side of the sliding plate 512 is fixedly connected to the lower end of the corresponding connecting plate one, and a fastening plate 513 is symmetrically fixed to the lower side of the sliding plate 512 through the connecting plate four. The side of the fastening plate 513 away from the corresponding connecting plate four is an arc surface that is symmetrical up and down.

[0045] When the sealing cover 31 is installed on the corresponding positioning plate 411, the sliding plate 512 is moved along the corresponding guide rod 511 in a direction away from the sealing cover 31. The sliding plate 512 then drives the fastening plate 513 to move synchronously through the fourth connecting plate. At the same time, the sliding plate 512 also drives the corresponding first connecting plate and its corresponding second sliding rod 343 to move synchronously in a direction away from the corresponding driving plate 341 until the driving plate 341 moves to the maximum distance. At this time, the fastening plate 513 has been completely and tightly inserted between the adjacent upper and lower second connecting plates and third connecting plates. The arc surface on the fastening plate 513 can ensure that the fastening plate 513 can be stably inserted between the second connecting plate and the third connecting plate. Thus, the third connecting plate and its corresponding pressing column 424 cannot move downward under the support of the fastening plate 513, enabling the elastic sleeve 422 and the corresponding clamping sleeve 412 to be stably installed without loosening, and further stably fixing and installing the sealing cover 31 on the conveying rack 1.

[0046] Please refer to Figure 3 、 Figure 5 and Figure 6 As shown in FIGS.

[0047] When the sealing covers 31 are sequentially and evenly installed on the upper side of the conveying rack 1 from front to back, the front ends of the docking plugs 522 come into contact with the adjacent front inclined limiting plates 526 and first move backward under the pressing cooperation with the inclined limiting plates 526 until the docking plugs 522 are aligned with the jacks one in the corresponding front docking seats 525. Under the elastic action of the elastic seats 521, the docking plugs 522 are inserted into the corresponding jacks one. The adjacent front and rear sliding plates 512 are stably docked together through the insertion cooperation of the docking plugs 522 and the docking seats 525. And at this time, the corresponding elastic sleeves 422 are also exactly completely docked and inserted into the corresponding clamping sleeves 412.

[0048] When all the sealing covers 31 are installed, all the sliding plates 512 on the same side are also stably docked together through the corresponding docking plugs 522 and docking seats 525. At this time, all the sliding plates 512 on the same side can be synchronously moved away from the corresponding sealing covers 31 until all the driving plates 341 are synchronously moved to the maximum distance. As a result, not only do all the fastening plates 513 exactly fix the corresponding sealing covers 31 on the conveying rack 1 stably and synchronously, but also all the driving plates 341 make the corresponding sealing rubber pads 333 and U-shaped frames 332 seal the seams between the corresponding two sealing covers 31 stably and synchronously.

[0049] Please refer to Figure 1 and Figure 3 and, the positioning mechanism 6 includes a sealing plate 61 installed on the front side of the front-end sealing cover 31 and the rear side of the rear-end sealing cover 31, and a positioning component 62 is arranged on the sealing plate 61.

[0050] Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 8 and, the positioning component 62 includes a front-to-back through observation window 621 opened on the sealing plate 61, and a transparent glass is installed in the observation window 621. On the front side of the front-end sealing plate 61, side blowing pipes 622 are symmetrically and fixedly arranged on the left and right. The side blowing pipes 622 are composed of a U-shaped blowing pipe one and a straight blowing pipe one communicated with the side communication grooves 321 symmetrically arranged up and down on the corresponding side. On the front side of the front-end sealing plate 61, an upper blowing pipe 623 is fixedly arranged. The upper blowing pipe 623 is composed of a U-shaped blowing pipe two and a straight blowing pipe two communicated with the upper communication grooves 323 symmetrically arranged on the left and right. On the left and right sides of the sealing plate 61, positioning members 624 are symmetrically installed by bolts. Among them, a front-to-back through jack two is opened on the front positioning member 624, and a plug post is fixedly arranged on the front side of the rear positioning member 624.

[0051] When all the sliding plates 512 on the same side are stably docked, first, all the sliding plates 512 on the same side fix all the sealing covers 31 on the conveying rack 1 stably through the corresponding fastening plates 513. At this time, then the positioning members 624 are respectively installed on the corresponding sealing plates 61 by bolts, so that the front docking plug 522 is stably inserted into the jack two on the front positioning member 624, and the plug post on the rear positioning member 624 is stably inserted into the jack one on the rear docking seat 525, thereby positioning all the sliding plates 512 synchronously and stably.

[0052] When any one of the sealing covers 31 on the conveying frame 1 needs to be disassembled, first pull the corresponding docking plug 522 of the sealing cover 31 backward, so that the through hole on the corresponding limiting block 523 of the docking plug 522 is aligned with the corresponding limiting seat 524 at the rear, and dock and position the limiting block 523 and the corresponding limiting seat 524 through a pin. Then, perform the docking and positioning of the corresponding docking plug 522 of the sealing cover 31 adjacent to the rear side of this sealing cover 31 through the same operation. At this time, press the corresponding connecting plate three to align the relief groove 425 on the corresponding pressing column 424 with the corresponding ball 423. Finally, the sealing cover 31 can be directly taken out upward. And due to the action of the front and rear positioning members 624, disassembling any one of the sealing covers 31 on the conveying frame 1 will not affect the stable installation of the remaining sealing covers 31.

[0053] The above operation method can not only achieve the segmented and rapid disassembly and installation of the sealing cover 31, but also achieve the synchronous and stable fastening of each segment and the synchronous and stable sealing of the screw conveying equipment. Thus, it not only greatly improves the overall disassembly and assembly efficiency of the sealing cover 31, increases the versatility, flexibility and application range of the sealing cover 31, reduces the overall cost of customizing the sealing cover 31, but also facilitates the segmented maintenance of the screw conveying equipment, improves the overall maintenance efficiency of the screw conveying equipment. At the same time, it also greatly reduces the overall operation burden of the operators and the overall labor cost, thereby improving the overall operation efficiency of the screw conveying equipment.

[0054] When all the sealing covers 31 are installed, the front and rear adjacent side communication grooves 321 and upper communication grooves 323 are also stably butted together. By introducing compressed air into the side blowing pipes 622 and upper blowing pipes 623, the compressed air passes through the respective side communication grooves 321 and upper communication grooves 323, and finally quickly sprays out to the outside of the corresponding filter cloths 334 through the respective blowing ports one 322 and blowing ports two 324. The respective filter cloths 334 vibrate accordingly, and the dust materials attached to the inner sides of the filter cloths 334 also fall off and fall downward into the conveying frame 1 for conveying. The above operation method not only greatly reduces the transportation loss of the materials and the overall material cost, but also reduces the overall cleaning burden of the operators.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
