[0002] Chemical pharmaceutical raw materials are the foundation of the pharmaceutical industry, covering a wide range of substances from natural products to synthetic compounds. These raw materials are processed through chemical reactions, biotechnology or physical methods and ultimately transformed into drugs with therapeutic effects. Chemical pharmaceutical raw materials are usually divided into liquid and solid. Liquid chemical pharmaceutical raw materials can be transported through pipelines, while solid chemical pharmaceutical raw materials are transported using conveying devices.

[0003] Patent No. CN113548392B discloses a telescopic conveyor that is convenient for adjusting the length of the belt, and relates to the field of telescopic conveyors, including a conveyor body, the conveyor body including a support frame, a connecting frame installed on the support frame, a fixed frame installed inside the connecting frame, a support seat fixed at the bottom of the support frame, a motor 1 and a motor 2 installed on one side of the support frame, and openings are opened on the support frame, the connecting frame and the fixed frame. The telescopic conveyor that is convenient for adjusting the length of the belt requires that when the device is tilted upward, according to the requirements of the tilt length, the connecting frame and the fixed frame can be rotated to tilt at the same time or the fixed frame can be tilted for use alone. When the fixed frame is tilted, the electric push rod pushes one end of the bottom of the fixed frame to separate from the connecting frame, and the adjusting device generates a pulling force on the transmission belt reeling at the same time, so that the fixed frame is tilted on the connecting frame through the fixed column, so as to meet the use in different situations. The conveyor pulls the conveyor belt through the adjusting device to make the connecting frame tilt and adjust the height, but when the connecting frame tilts to a certain angle, the material will roll down, thereby causing the accumulation of the material, which is inconvenient for the transportation of the material.

[0024] See also Figure 1-Figure 5 The present invention provides an embodiment: a chemical pharmaceutical raw material conveying device, comprising: a main frame 100, a driving mechanism 200 for providing driving force is installed on the side of the main frame 100, a conveyor belt 300 for transmitting pharmaceutical raw materials is rotatably installed on the main frame 100, and a main dust cover 400 for dust prevention is installed on the main frame 100; It should be understood that the pharmaceutical raw materials are transported to the conveyor belt 300 through the feed port 410 on the main dust cover 400. At this time, the driving mechanism 200 can drive the conveyor belt 300 to rotate when it is working. When the conveyor belt 300 rotates, the pharmaceutical raw materials can be transported. When the pharmaceutical raw materials are transported to the discharge port 440 on the side of the main dust cover 400, they can be unloaded.

[0025] like Figure 1-Figure 5 , Fig. 9As shown, the main frame 100 includes a sub-frame 110 for conveying pharmaceutical raw materials at a high place, and an extension frame 120 for conveying pharmaceutical raw materials over a long distance. The sub-frame 110 is rotatably mounted on one side of the main frame 100, and the extension frame 120 is movably connected to the side of the sub-frame 110 away from the main frame 100. A conveyor belt 300 is connected between the main frame 100, the sub-frame 110 and the extension frame 120 through rollers, and a driving mechanism 200 is installed on the side of the extension frame 120. It can be imagined that when the pharmaceutical raw materials need to be output to a high place, the sub-frame 110 can be driven to rotate along the side of the main frame 100 through the cooperation of the components, and the sub-frame 110 can drive the conveyor belt 300 to bend while rotating. When the sub-frame 110 rotates to a specified position, the conveyor belt 300 can transport the pharmaceutical raw materials to different heights; When the pharmaceutical raw materials need to be transported over a long distance, the extension frame 120 can be pushed to move by the cooperation of parts. When the extension frame 120 moves, the conveyor belt 300 can be extended. After the conveyor belt 300 is extended, the pharmaceutical raw materials can be transported.

[0026] like Figure 3-Figure 5 , Figure 7 , Fig.11 and Fig.13 As shown, the conveyor belt 300 includes a baffle 310 for blocking pharmaceutical raw materials, and an extended baffle 320 for preventing the pharmaceutical raw materials from rolling down. The baffle 310 is rotatably mounted on the conveyor belt 300, and the extended baffle 320 is rotatably mounted on the baffle 310; It is worth noting that when the conveyor belt 300 rotates, the baffle bar 310 can be driven to move. When the baffle bar 310 moves, it can push and block the pharmaceutical raw materials. When the sub-frame 110 adjusts its height, the extended baffle bar 320 can be rotated and unfolded with the bending of the conveyor belt 300. After the extended baffle bar 320 is rotated and unfolded, the height of the baffle bar 310 can be increased to improve the blocking effect.

[0027] like Figure 1-Figure 4 , Figure 6 , Figure 7 and Fig.12 As shown, the main dust cover 400 includes a secondary dust cover 421 for dust protection of the secondary frame 110, a folding cover 420 for rotatably connecting the main dust cover 400 and the secondary dust cover 421, and an extended dust cover 430 for dust protection of the extension frame 120. The secondary dust cover 421 is fixedly installed on the top and bottom of the secondary frame 110, and the secondary dust cover 421 and the main dust cover 400 are connected to each other through the folding cover 420. The extension dust cover 430 is fixedly installed on the top and bottom of the extension frame 120, and the side of the extension dust cover 430 is movably connected to the inside of the secondary dust cover 421. It should be noted that when the height of the auxiliary frame 110 is adjusted, the auxiliary dust cover 421 can be driven to adjust its height, and when the height of the auxiliary dust cover 421 is adjusted, the folding cover 420 can be bent, and when the folding cover 420 is bent, the main dust cover 400 and the auxiliary dust cover 421 can always be connected to each other; When the extension frame 120 is adjusted in length, the extension dust cover 430 can be driven to move, and the extension dust cover 430 can slide in the auxiliary dust cover 421 when moving.

[0028] like Figure 1-Figure 3 , Figure 6 and Fig. 9 As shown, the sub-frame 110 includes a hinge 111 for rotation and a telescopic frame 115 for lifting the sub-frame 110. The sub-frame 110 is connected to the main frame 100 through the hinge 111, and the telescopic frame 115 is movably installed at the bottom of the sub-frame 110; It can be understood that the telescopic frame 115 can drive the auxiliary frame 110 to adjust its height when in operation, and the auxiliary frame 110 can rotate with the main frame 100 through the hinge 111 when the height is adjusted.

[0029] like Figure 3 and Figure 6 As shown, the sub-frame 110 further includes a connecting shaft 114 for rotating the end of the telescopic frame 115, and a slide rail 112 and a slider 113 for providing a lifting and moving space for the telescopic frame 115. The connecting shaft 114 is installed on the top of the telescopic frame 115, and the slider 113 is fixedly installed on the side of the connecting shaft 114. The slide rails 112 are fixedly installed on the front and rear sides of the sub-frame 110, and the slider 113 is movably installed inside the slide rails 112. It can be imagined that when the telescopic frame 115 is working, it can push the connecting shaft 114 to move, and when the connecting shaft 114 moves, it rotates with the slider 113. While the connecting shaft 114 and the slider 113 rotate, the connecting shaft 114 can push the slider 113 to slide in the slide rail 112, and while the slider 113 slides in the slide rail 112, the height of the sub-frame 110 can be adjusted through the slide rail 112.

[0030] like Figure 3 , Figure 4 and Fig. 9 As shown, the extension frame 120 includes a slide 121 for limiting, and an internally threaded sleeve 122 and a first threaded screw 123 for moving the extension frame 120. The slide 121 is fixedly installed on one side of the extension frame 120 close to the auxiliary frame 110. The slide 121 is movably connected inside the assembly groove of the auxiliary frame 110. The internally threaded sleeve 122 is fixedly installed inside the slide 121. The internally threaded sleeve 122 is threadedly connected with the first threaded screw 123. The side of the first threaded screw 123 is rotatably installed inside the assembly groove of the auxiliary frame 110 through a bearing seat. It is worth noting that when the first threaded screw 123 rotates, it drives the internal threaded sleeve 122 to slide threadedly. When the internal threaded sleeve 122 slides threadedly, it pushes the slide 121 to move. When the slide 121 moves, it can slide inside the cavity of the sub-frame 110. When the slide 121 slides, it drives the extension frame 120 to move.

[0031] like Figure 1-Figure 4 , Fig. 9 and Fig.10 As shown, the extension frame 120 also includes a universal shaft 124 that can provide driving force when the first threaded screw 123 adjusts the angle, a first rotating rod 125 for rotating the universal shaft 124, a second rotating rod 126 and a reduction motor 127 for rotating the first rotating rod 125, the universal shaft 124 is fixedly installed at the end of the first threaded screw 123 close to the assembly groove of the main frame 100, the first rotating rod 125 is fixedly installed at the other end of the universal shaft 124, the second rotating rod 126 is rotatably installed through the assembly grooves of the main frame 100, one end of the second rotating rod 126 extends out of the front of the main frame 100 and is connected to the output end of the reduction motor 127, and the side of the reduction motor 127 close to the output end is fixedly installed at the front of the main frame 100 by bolts; It should be understood that when the reduction motor 127 is working, it drives the second rotating rod 126 to rotate. When the second rotating rod 126 rotates, it drives the first rotating rod 125 to rotate through the cooperation of the bevel gear 1210. When the first rotating rod 125 rotates, it drives the universal shaft 124 to rotate. When the universal shaft 124 rotates, it drives the first threaded screw 123 to rotate. When the height of one side of the auxiliary frame 110 is adjusted, the second rotating rod 126 can transmit the first threaded screw 123 through the cooperation of the universal shaft 124 .

[0032] like Figure 1-Figure 5 As shown, the extension frame 120 also includes a movable roller 1212 for extending and contracting the conveyor belt 300, a positioning roller 1213 for limiting the conveyor belt 300, and an internal threaded slider 1211, a second threaded screw 129, and a mounting cover 128 for the movable roller 1212 to move up and down. The mounting cover 128 is fixedly installed at the bottom of the main frame 100, and the second threaded screw 129 is rotatably installed inside the assembly groove of the mounting cover 128. The top of the second threaded screw 129 passes through the bottom of the main frame 100 and is connected to the assembly groove of the main frame 100. The surface of the second threaded screw 129 is threadedly connected with an internal threaded slider 1211 matching the assembly groove of the mounting cover 128. The movable roller 1212 is rotatably installed between the internal threaded sliders 1211, and positioning rollers 1213 are installed at the bottom of the main frame 100 near the left and right sides of the mounting cover 128. It can be understood that when the second threaded screw 129 rotates, it can drive the internal threaded slider 1211 to slide in a threaded manner. When the internal threaded slider 1211 slides in a threaded manner, it can slide inside the mounting cover 128. When the internal threaded slider 1211 slides, it can drive the movable roller 1212 to rise and fall. When the movable roller 1212 rises, the conveyor belt 300 can be unfolded. When the movable roller 1212 descends, the conveyor belt 300 can be retracted. The positioning roller 1213 can limit the conveyor belt 300 when the conveyor belt 300 is unfolded or retracted.

[0033] like Figure 3 , Figure 4 and Fig.10 As shown, the extension frame 120 also includes a bevel gear 1210 for mutual transmission between the first rotating rod 125, the second rotating rod 126 and the second threaded screw 129, and the first rotating rod 125, the second threaded screw 129 and the second rotating rod 126 are all equipped with matching bevel gears 1210; It is conceivable that the reduction motor 127 can drive the second rotating rod 126 to rotate when it is working, and when the second rotating rod 126 rotates, it can drive the first rotating rod 125 and the second threaded screw 129 to rotate through the cooperation of the bevel gear 1210.

[0034] like Figure 4 , Figure 5 , Figure 7 , Fig.11 and Fig.13 As shown, the baffle bar 310 includes a first reset member 311 for rotation, and a mounting groove 312 for mounting the baffle bar 310 and the first reset member 311. The first reset member 311 is rotatably mounted on both ends of the baffle bar 310. The first reset member 311 is provided with a rotating shaft and a torsion spring to enable the baffle bar 310 to rotate and reset. The conveyor belt 300 is provided with a mounting groove 312, and the first reset member 311 and the baffle bar 310 are mounted inside the mounting groove 312. It is worth noting that when the conveyor belt 300 rotates, the baffle bar 310 on the surface is driven to move. When the baffle bar 310 moves to the side of the positioning roller 1213, it will be pushed. When the baffle bar 310 is pushed, it can be rotated by the first reset member 311. When the baffle bar 310 is rotated to the inside of the installation groove 312, it can be flush with the conveyor belt 300. When the conveyor belt 300 drives the baffle bar 310 to pass through the surface of the positioning roller 1213, the baffle bar 310 can be reset by the first reset member 311.

[0035] like Figure 1-Figure 5 , Figure 7 , Fig. 9 , Fig.11 and Fig.13As shown, the blocking bar 310 also includes a positioning plate 313 for positioning the conveyor belt 300, and a limiting bar 314 and a limiting groove 315 for limiting the blocking bar 310. The inner sides of the main frame 100, the auxiliary frame 110 and the extension frame 120 are all fixedly installed with the positioning plates 313. The positioning plates 313 on the auxiliary frame 110 and the extension frame 120 are staggered. The positioning plates 313 are fixedly installed with the limiting bars 314 on the sides of the positioning plates 313 close to the auxiliary frame 110 and the extension frame 120. The limiting grooves 315 matching the limiting bars 314 are opened at both ends of the blocking bar 310. It should be understood that when the conveyor belt 300 rotates, it can drive the baffle bar 310 to move, and when the baffle bar 310 moves, it can drive the limiting groove 315 to move. When the baffle bar 310 moves to the side of the positioning plate 313, the baffle bar 310 can drive the limiting groove 315 to slide on the surface of the limiting bar 314. When the limiting groove 315 slides, the limiting bar 314 can limit the baffle bar 310, so that the baffle bar 310 can be prevented from rotating when it is pushed.

[0036] like Figure 4 , Figure 5 , Figure 7 , Fig.11 and Fig.13 As shown, the extended stop bar 320 includes a magnet 321 for being attached to the surface of the stop bar 310, a half-moon gear 322 for rotating the extended stop bar 320, and a clamping piece 323 for fixing the extended stop bar 320 after being unfolded. The surfaces of the extended stop bar 320 and the stop bar 310 are fixedly installed with the magnet 321 through an assembly groove, and the connection between the extended stop bar 320 and the stop bar 310 is fixedly installed with a half-moon gear 322 through a rotating shaft, and a clamping piece 323 is installed on the side of the half-moon gear 322, and the clamping piece 323 is mutually clamped and connected through a clamping block and a clamping groove on the side of the stop bar 310; It can be imagined that when the half-moon gear 322 rotates, the extension baffle 320 can be driven to rotate through the rotating shaft. When the extension baffle 320 rotates, the two magnets 321 can be separated. After the magnets 321 are separated, one side of the extension baffle 320 will flip along the top of the baffle 310. When the half-moon gear 322 rotates, the locking block of the locking member 323 can be driven to rotate. When the half-moon gear 322 rotates 180°, the locking block of the locking member 323 can be locked and connected with the slot on the baffle 310. After the locking block is locked and connected with the slot, the extension baffle 320 can be positioned.

[0037] like Figure 3-Figure 5 and Figure 7-Figure 9 , Figure 11-13As shown, the extended stop bar 320 also includes a lower movable plate 329 for rotating the half-moon gear 322, a gear 325 and an upper movable plate 327 for moving the lower movable plate 329, and a mounting shell 324 for mounting the lower movable plate 329, the gear 325 and the upper movable plate 327, the inner side of the auxiliary dust cover 421 is fixedly mounted with the mounting shell 324, the bottom of the inner cavity of the mounting shell 324 is movably mounted with the lower movable plate 329, the top of the inner cavity of the mounting shell 324 is movably mounted with the upper movable plate 327, the upper surface of the lower movable plate 329 and the lower surface of the upper movable plate 327 are connected with a matching gear 325 through a tooth groove, the end of the lower movable plate 329 close to the stop bar 310 is provided with a tooth block matching the half-moon gear 322, the end of the upper movable plate 327 close to the auxiliary dust cover 421 is provided with a round rod with an inclined end, and the round rod end of the upper movable plate 327 passes through the inner side of the auxiliary dust cover 421; It should be noted that when the round rod at the end of the upper movable plate 327 is separated from the baffle rod 328, the gear 325 can be rotated through the cooperation of the second reset piece 326. When the gear 325 rotates, it can drive the upper movable plate 327 and the lower movable plate 329 to engage and move. When the upper movable plate 327 and the lower movable plate 329 engage and move, they can slide in opposite directions inside the mounting shell 324. When the lower movable plate 329 slides, it can drive the surface tooth block to move to the moving path of the half-moon gear 322. When the half-moon gear 322 moves to the tooth block of the lower movable plate 329, it can engage and rotate. When the half-moon gear 322 moves out of the tooth block surface of the lower movable plate 329, it can rotate 180°.

[0038] like Figure 1-Figure 5 and Figure 7-Figure 9 , Fig.11 As shown, the extension baffle 320 also includes a second reset member 326 for resetting the gear 325, a push rod 3210 for pushing the extension baffle 320 to fold, and a stop rod 328 for pushing the upper movable plate 327. The second reset member 326 is installed on both sides of the right side of the mounting shell 324. The second reset member 326 is connected to the gear 325 through a rotating shaft. The push rod 3210 is fixedly installed on the inner side of the extension dust cover 430, and the stop rod 328 is fixedly installed on the surface of the main dust cover 400 near the end of the upper movable plate 327. It should be understood that the second reset member 326 can apply a pre-tightening force to the gear 325 through the torsion spring, and when the sub-frame 110 rotates, it can drive the round rod of the upper movable plate 327 to move. When the end of the round rod of the upper movable plate 327 is separated from the surface of the baffle rod 328, the torsion spring can drive the gear 325 to rotate through the rotating shaft. When the conveyor belt 300 drives the extended baffle bar 320 to move to the side of the pushing rod 3210, the pushing rod 3210 can push the surface of the extended baffle bar 320, and the extended baffle bar 320 can rotate with the baffle bar 310 when pushed.

[0039] like Figure 1-Figure 5 As shown, the main dust cover 400 also includes a feed port 410 for adding pharmaceutical raw materials, and a discharge port 440 for discharging pharmaceutical raw materials. The feed port 410 is fixedly installed on the upper surface of the main dust cover 400, and the discharge port 440 is opened at the bottom of the extended dust cover 430; It is conceivable that the pharmaceutical raw materials can be transported to the conveyor belt 300 through the feed port 410 , and the conveyor belt 300 can drive the pharmaceutical raw materials to be transported when it rotates. When the pharmaceutical raw materials move to the end of the extension frame 120 , the conveyor belt 300 can discharge the pharmaceutical raw materials through the discharge port 440 .
