[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.

[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.

[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 the direction away from the sealing cover 31, and the sliding plate 512 drives the fastening plate 513 to move synchronously through the connecting plate 4. At the same time, the sliding plate 512 also drives the corresponding connecting plate 1 and its corresponding sliding rod 2 343 to move synchronously in the 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 into the corresponding upper and lower adjacent connecting plates 2 and 3. The arc surface on the fastening plate 513 can ensure that the fastening plate 513 can be stably inserted between the connecting plates 2 and 3, so that the supporting of the fastening plate 513 makes the connecting plate 3 and its corresponding pressing column 424 unable to move downward, so that the elastic sleeve 422 and the corresponding clamping sleeve 412 can be stably installed without loosening, and then the sealing cover 31 is stably fixed on the conveying frame 1.

[0046] See also Figure 3 , Figure 5 and Figure 6 The docking assembly 52 includes an elastic seat 521 fixedly arranged at the front end of the sliding plate 512, a docking plug 522 that moves forward and backward is elastically slidably arranged in the elastic seat 521, a limiting block 523 is fixedly arranged at the rear end of the docking plug 522, and a through hole that passes through the left and right is opened on the limiting block 523, a limiting seat 524 that is docked and positioned with the limiting block 523 through a pin is fixedly arranged on the sliding plate 512 and located behind the limiting block 523, a docking seat 525 is fixedly arranged at the rear end of the sliding plate 512, and a socket 1 that passes through the front and back is opened on the docking seat 525, and an oblique limiting plate 526 is fixedly arranged on the upper side of the docking seat 525.

[0047] When each sealing cover 31 is evenly installed on the upper side of the conveying frame 1 from front to back, the front end of each docking plug-in 522 contacts the adjacent oblique limiting plate 526 on the front side, and moves backwards under the pressure-moving fit with the oblique limiting plate 526 until the docking plug-in 522 is aligned with the socket 1 in the docking seat 525 on its front side. Under the elastic action of the elastic seat 521, the docking plug-in 522 is inserted into the corresponding socket 1, and the corresponding front and rear adjacent sliding plates 512 are stably docked together through the plug-in fit of the docking plug-in 522 and the docking seat 525, and at this time, the corresponding elastic sleeve 422 is also completely docked and inserted into the corresponding clamping sleeve 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 each driving plate 341 is synchronously moved to the maximum distance. Therefore, not only each fastening plate 513 can synchronously and stably fix the corresponding sealing cover 31 on the conveying frame 1, but each driving plate 341 can also synchronously and stably seal the joint between the corresponding two sealing covers 31 with the corresponding sealing pads 333 and U-shaped frames 332.

[0049] See also Figure 1 and Figure 3 The positioning mechanism 6 includes a sealing plate 61 installed on the front side of the front sealing cover 31 and the rear side of the rear sealing cover 31 , and a positioning component 62 is provided on the sealing plate 61 .

[0050] See also Figure 3 , Figure 4 , Figure 6 and Figure 8 The positioning assembly 62 includes an observation window 621 that is opened on the sealing plate 61 and passes through from front to back, and transparent glass is installed in the observation window 621. A side blowing pipe 622 is fixedly arranged on the front side of the front sealing plate 61 symmetrically. The side blowing pipe 622 consists of a U-shaped blowing pipe 1 and a straight blowing pipe 1 connected to the side connecting groove 321 symmetrically on the corresponding side. An upper blowing pipe 623 is fixedly arranged on the front side of the front sealing plate 61. The upper blowing pipe 623 consists of a U-shaped blowing pipe 2 and a straight blowing pipe 2 connected to the upper connecting groove 323 symmetrically on the left and right. Positioning members 624 are symmetrically installed on the left and right sides of the sealing plate 61 by bolts, wherein the front positioning member 624 is provided with two sockets that pass through from front to back, and a plug column 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 stably fix all the sealing covers 31 on the conveying frame 1 through the corresponding fastening plates 513. At this time, each positioning member 624 is installed on the corresponding sealing plate 61 by bolts, so that the front end docking plug-in 522 is stably inserted into the second hole on the front end positioning member 624, and the plug column on the rear end positioning member 624 is stably inserted into the first hole on the rear end docking seat 525, so that all the sliding plates 512 are synchronously and stably positioned.

[0052] When any sealing cover 31 on the conveying rack 1 is to be removed, the docking plug-in 522 corresponding to the sealing cover 31 is first pulled backwards to align the through hole on the limit block 523 corresponding to the docking plug-in 522 with the corresponding limit seat 524 at the rear, and the limit block 523 is docked and positioned with the corresponding limit seat 524 through the latch, and then the docking plug-in 522 corresponding to the adjacent sealing cover 31 on the rear side of the sealing cover 31 is docked and positioned through the same operation, and then the corresponding connecting plate 3 is pressed to align the corresponding yield groove 425 on the pressing column 424 with the corresponding ball 423, and finally the sealing cover 31 can be directly taken out upwards, and due to the action of the front and rear end positioning members 624, the removal of any sealing cover 31 on the conveying rack 1 will not affect the stable installation of the remaining sealing covers 31.

[0053] The above-mentioned operation method can not only realize the rapid disassembly and installation of the sealing cover 31 in sections, but also realize the synchronous and stable tightening of each section and the synchronous and stable sealing of the screw conveying equipment, thereby greatly improving the efficiency of the overall disassembly and assembly of the sealing cover 31, increasing the versatility, flexibility and application scope of the sealing cover 31, reducing the overall cost of customizing the sealing cover 31, facilitating the segmented maintenance of the screw conveying equipment, improving the overall maintenance efficiency of the screw conveying equipment, and at the same time greatly reducing the overall work burden of the operating personnel, reducing the overall labor cost, and thus improving the overall operating efficiency of the screw conveying equipment.

[0054] When all the sealing covers 31 are installed, the front and rear adjacent side connecting grooves 321 and upper connecting grooves 323 are also stably connected together front and back, and compressed air is introduced into the side blowing pipes 622 and the upper blowing pipes 623 to pass the compressed air through the side connecting grooves 321 and the upper connecting grooves 323, and finally the compressed air is quickly sprayed to the outside of the corresponding filter cloth 334 through the corresponding blowing ports 1 322 and 324. Each filter cloth 334 vibrates accordingly, and the dust material attached to the inner side of the filter cloth 334 also falls off and falls downward into the conveying frame 1 for transportation. The above-mentioned operation method not only greatly reduces the transportation loss of materials and the overall material cost, but also reduces the overall cleaning burden of the operating personnel.
