Description

Technical Field

[0001] The present application relates to the technical field of salt material transportation, and in particular to a screw conveying device for discharging salt material. Background Art

[0002] The salt industry occupies an important position in the national economy. Salt is widely used in food processing, chemical industry, pharmaceuticals and other fields. With the continuous development of these industries, the requirements for the output and quality of salt are also constantly increasing. In the production process of salt, efficient and reliable conveying devices are needed to transport salt from one link to another to meet the needs of continuous production. For this reason, the use of spiral conveying equipment for salt is becoming more and more widespread.

[0003] However, in the process of conveying salt, the existing spiral feeding equipment mostly needs to adjust the feeding height of the feeding barrel according to the actual needs of the site and equipment. When the feeding height is raised, the feed hopper is not level with the ground, so that the flow direction of the salt under the action of gravity will change. The salt may no longer be evenly distributed on the cross-section of the feed hopper, but tend to flow to the lower side, which will cause uneven distribution of salt in the feed hopper and affect the subsequent conveying process. At the same time, the salt may accumulate on one side of the feed hopper and relatively less on the other side, thereby affecting the feeding stability of the spiral conveying device and easily causing the accumulated salt to clump, further affecting the quality of the salt. Summary of the invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a spiral conveying device for discharging salt, which starts a cylinder to adjust the discharging height of the transmission barrel, adjusts the vibration amplitude by angle change, reduces the accumulation of salt in the feed hopper, and promotes uniform distribution of salt. The inclination angle matches the vibration amplitude to ensure that the salt is stably transmitted without being blocked or vibrated out. When adjusting the vibration amplitude, the salt can be stirred to ensure stable transmission, and the salt agglomeration problem can be improved by breaking up and stirring to ensure transmission quality. The vibration and breaking up degree are adjusted according to the lifting height of the transmission barrel to reduce the agglomeration and residue problems of the salt.

The feeding mechanism 1 is lifted upward to drive the vibration amplitude adjusting mechanism 2, and the vibration amplitude adjusting mechanism 2 adjusts the vibration amplitude of the vibration anti-blocking mechanism 3. The higher the lifting height of the feeding mechanism 1 is, the greater the vibration amplitude of the vibration anti-blocking mechanism 3 is. There is a reciprocating anti-blocking mechanism 4, which is located at the front end of the upper part of the feeding mechanism 1, and the reciprocating anti-blocking mechanism 4 is located at the rear end of the vibration anti-blocking mechanism 3. The reciprocating movement of the vibration anti-blocking mechanism 3 drives the reciprocating anti-blocking mechanism 4 to move back and forth, and the reciprocating anti-blocking mechanism 4 moves back and forth inside the feeding mechanism 1 to achieve an anti-blocking effect.

[0049] When in use, the feeding height of the feeding mechanism 1 can be adjusted by starting the cylinder 102.

The middle part of the outer wall at the rear end of the L-shaped frame 326 is fixedly connected to the extrusion boss 329. The upper part of the front end of the transmission cylinder 103 is fixedly connected to the feed hopper 112, and the lower part of the front end of the feed hopper 112 is provided with an assembly hole 114, and the interior of the assembly hole 114 is fixedly connected to the vibration frame 330. The rear ends of the upper surface of the mounting platform 301 are respectively provided with sliding grooves 310. The rear ends of the lower surface of the U-shaped plate 307 are fixedly connected to the sliding blocks 311, and the sliding blocks 311 are slidably connected inside the sliding grooves 310. The outer wall at the front end of the baffle 309 is fixedly connected to the buffer seat 312.The inner wall of the rear end of the buffer seat 312 is fixedly connected with a plurality of buffer springs 313, and the front ends of the buffer springs 313 are fixedly connected with the buffer pressure plates 314, and the rear end of the extrusion plate 328 is tightly fitted with the front end of the buffer pressure plate 314. The vibration frame 330 is slidably connected with the vibration cover 331 inside, and the two sides of the inner wall of the front end of the vibration frame 330 are fixedly connected with the fixing plates 332, and the upper and lower parts of the outer wall of the rear end of the fixing plate 332 are respectively fixedly connected with the return springs 333, and the rear ends of the return springs 333 are fixedly connected with the inner wall of the rear end of the vibration cover 331, and the middle part of the inner wall of the rear end of the vibration cover 331 is fixedly connected with the pressure boss 334, and the outer wall of the rear end of the extrusion boss 329 is fitted with the outer wall of the front end of the pressure boss 334. During the process, when it is necessary to adjust the feeding height of the feeding mechanism 1, the height of the transmission cylinder 103 can be adjusted by starting the cylinder 102, and the intermediate gear cylinder 209 will rotate clockwise synchronously with the coarse gear cylinder 207. At this time, the intermediate gear cylinder 209 will mesh with the driven teeth 308 and move the U-shaped plate 307 toward the direction of the feed hopper 112. When the transmission cylinder 103 reaches the discharge height, the cylinder 102 stops, and the transmission cylinder 103 no longer lifts upward. At this time, the intermediate gear cylinder 209 stops rotating and stops the U-shaped plate 307, the baffle 309 and the buffer seat 312 from moving. At this time, under the action of the vibration spring 305, the adapter plate 304 begins to drive the reciprocating gear plate 316, the L-shaped frame 326, the connecting rod 327 and the extrusion plate 328 toward the transmission cylinder 103 moves, when the extrusion plate 328 contacts the buffer pressure plate 314, the positions of the adapter plate 304 and the reciprocating tooth plate 316 are restricted again, and the number of teeth of the reciprocating tooth plate 316 meshing with the half-tooth cylinder 325 also begins to increase. At the same time, during the movement of the L-shaped frame 326, the extrusion boss 329 will also push the pressure boss 334 and the vibration cover 331 to move inside the vibration frame 330. After the feeding height of the feeding mechanism 1 is determined, the servo motor 107 is started again to make the auger blade 109 rotate, and drive the short shaft 319 and the third bevel gear 320 to rotate. At this time, the third bevel gear 320 and the fourth bevel gear 322 are meshed with each other and make the fourth rotating rod 321 rotate. At this time, the second transmission wheel 323 and the second gear are engaged. Under the action of the belt 324, the third rotating rod 318 starts to drive the half-tooth cylinder 325 to rotate. During the rotation of the half-tooth cylinder 325, it will mesh with the reciprocating tooth plate 316, and the reciprocating tooth plate 316 drives the L-shaped frame 326 and the extrusion boss 329 to move in the direction away from the transmission cylinder 103. When the half-tooth cylinder 325 is not meshed with the reciprocating tooth plate 316, the extrusion boss 329 will start to reset and knock the compressed boss 334 under the action of the vibration spring 305, and the compressed boss 334 drives the vibration cover 331 to start vibrating at the front end of the feed hopper 112, thereby reducing the phenomenon of salt accumulation inside the feed hopper 112. At the same time, the higher the height of the transmission cylinder 103 is lifted, the more teeth of the intermediate tooth cylinder 209 mesh with the driven teeth 308.The U-shaped plate 307 drives the baffle plate 309 to move toward the transmission cylinder 103. The reciprocating tooth plate 316 moves toward the transmission cylinder 103 under the action of the vibration spring 305. As a result, the number of teeth of the reciprocating tooth plate 316 meshing with the half-tooth cylinder 325 increases. The distance that the extrusion boss 329 knocks against the pressure boss 334 under the action of the vibration spring 305 also begins to increase, and the amplitude of the vibration cover 331 vibrating the salt material also begins to increase, thereby reducing the amount of salt material in the feed hopper 112. The problem of salt accumulation occurs inside the feed hopper 112. The higher the height of the transmission cylinder 103 is lifted, the greater the vibration amplitude of the vibration cover 331 inside the feed hopper 112, which further reduces the phenomenon of salt accumulation inside the feed hopper 112. At the same time, when the vibration cover 331 moves into the feed hopper 112, the stroke of the return spring 333 will increase, and the elasticity when returning will increase. At this time, the vibration generated by the vibration cover 331 will also disperse the salt inside the feed hopper 112, further improving the stability of salt transmission.

[0053] like Fig.12 and Fig.13The reciprocating anti-blocking mechanism 4 includes a reciprocating slide plate 401 and an active tooth plate 408. The outer wall of the front end of the reciprocating slide plate 401 is fixedly connected to the rear end of the lower part of the L-shaped frame 326. The two sides of the outer wall of the rear end of the reciprocating slide plate 401 are rotatably connected with reciprocating rods 402. The rear ends of the reciprocating rods 402 extend to the inside of the feed hopper 112. The outer walls of the reciprocating rods 402 are respectively fixedly connected with a plurality of stirring blades 403. The outer walls of the front ends of the reciprocating rods 402 are fixedly connected with fifth bevel gears 404. The middle part of the outer wall of the rear end of the reciprocating slide plate 401 is rotatably connected with a fifth rotating rod 405. The middle part of the outer wall of the fifth rotating rod 405 is fixedly connected with a driven gear cylinder 406. The outer walls on both sides of the fifth rotating rod 405 are fixedly connected with sixth bevel gears 407. The fifth bevel gears 404 are respectively connected to the sixth bevel gears 407. The gears 407 mesh with each other, and a driving tooth plate 408 is fixedly connected to the middle of the rear end of the upper surface of the mounting platform 301, and the driven gear cylinder 406 meshes with the driving tooth plate 408. Specifically, in the process of transmitting and discharging salt material, when it is necessary to adjust the feeding height of the feeding mechanism 1, the transmission cylinder 103 can be height-adjusted by starting the cylinder 102, and at the same time, starting the servo motor 107 can rotate the auger blade 109 and rotate the half-tooth cylinder 325. At this time, the reciprocating tooth plate 316 will move back and forth in a cycle during the rotation of the half-tooth cylinder 325, and at the same time, the L-shaped frame 326 will drive the reciprocating slide plate 401 and the reciprocating rod 402 to move back and forth. At this time, the stirring blade 403 can break up the salt material during the reciprocating movement inside the feed hopper 112. In this way, the salt material is prevented from being blocked inside the feed hopper 112. At the same time, during the reciprocating movement of the reciprocating slide plate 401, the driven gear cylinder 406 will mesh with the active gear plate 408. At this time, the sixth bevel gear 407 and the fifth bevel gear 404 mesh with each other and rotate the reciprocating rod 402 and the stirring blade 403, so that the salt material inside the feed hopper 112 can be efficiently dispersed, further reducing the occurrence of blockage inside the feed hopper 112. Among them, the discharge height of the transmission cylinder 103 is adjusted by starting the cylinder 102. First, the angle change of the transmission cylinder 103 when adjusting the discharge height is used to make the vibration amplitude adjustment mechanism 2 drive the vibration anti-blocking mechanism 3 to adjust the vibration amplitude, thereby effectively reducing the The phenomenon of salt accumulation in the feed hopper 112 is promoted, which makes the salt material evenly distributed inside the feed hopper 112 and ensures the stability of the later transportation process of the salt material. Secondly, the inclination angle of the transmission cylinder 103 matches the vibration amplitude of the vibration cover 331, thereby ensuring that the salt material will not be blocked and that the salt material will not be vibrated out of the feed hopper 112 by the vibration cover 331, thereby ensuring the stable transmission of the salt material. Thirdly, while adjusting the vibration amplitude of the vibration cover 331, the salt material inside the feed hopper 112 can be stirred, thereby ensuring the stability of the salt material transmission. Fourthly, by breaking up and stirring the salt material, the agglomeration problem of the salt material in the transmission process can be effectively improved, and the quality of the salt material transmission can be further guaranteed. Fifthly, according to the lifting height of the transmission cylinder 103,Adjusting the degree of vibration and breaking up the salt material can effectively reduce the problem of salt material agglomeration and accumulation inside the feed hopper 112 during the transmission process.

[0054] Specifically, the working principle of the spiral conveying device for salt discharge is as follows: during the process of transporting and discharging the salt, the first bevel gear 108 and the second bevel gear 110 can be meshed with each other by starting the servo motor 107, thereby rotating the auger blade 109, so that the salt can be transported inside the transmission cylinder 103. When the feeding height of the feeding mechanism 1 needs to be adjusted, the transmission cylinder 103 can be lifted upward by starting the cylinder 102, thereby adjusting the discharge height of the discharge cover 113. When the feeding height of the feeding mechanism 1 needs to be adjusted, the transmission cylinder 103 can be adjusted in height by starting the cylinder 102, and the transmission cylinder 103 will drive the semi-arc connecting seat 105 to rotate counterclockwise. During the process of mutual meshing of the active teeth 106 and the sliding tooth plate 203, the middle tooth plate 204 starts to move downward and drives the coarse tooth cylinder 207 to rotate clockwise. At this time, under the action of the first transmission wheel 210 and the first toothed belt 211, the middle tooth cylinder 209 starts to rotate synchronously, and at the same time, the middle tooth cylinder 209 will rotate synchronously clockwise with the coarse tooth cylinder 207. At this time, the middle tooth cylinder 209 will mesh with the driven teeth 308 and make the U-shaped plate 307 move toward the direction of the feed hopper 112. When the transmission cylinder 103 reaches the discharge height, the cylinder 102 stops, and the transmission cylinder 103 no longer lifts upward. At this time, the middle tooth cylinder 209 stops rotating and makes the U-shaped plate 307, the baffle 309 and the buffer seat 312 stop moving. At this time, under the action of the vibration spring 305, The adapter plate 304 starts to drive the reciprocating tooth plate 316, the L-shaped frame 326, the connecting rod 327 and the extrusion plate 328 to move toward the position of the transmission cylinder 103. When the extrusion plate 328 contacts the buffer pressure plate 314, the position of the adapter plate 304 and the reciprocating tooth plate 316 is restricted again. At the same time, the number of teeth of the reciprocating tooth plate 316 meshing with the half-tooth cylinder 325 also begins to increase. At the same time, during the movement of the L-shaped frame 326, the extrusion boss 329 will also push the pressure boss 334 and the vibration cover 331 to move inside the vibration frame 330. When the feeding height of the feeding mechanism 1 is determined, starting the servo motor 107 again can make the auger blade 109 rotate, and drive the short shaft 319 and the third bevel gear 320 to rotate. At this time, the third bevel gear 320 The third rotating rod 318 meshes with the fourth bevel gear 322 and causes the fourth rotating rod 321 to rotate. At this time, under the action of the second transmission wheel 323 and the second toothed belt 324, the third rotating rod 318 begins to drive the half-tooth cylinder 325 to rotate. During the rotation of the half-tooth cylinder 325, it will mesh with the reciprocating tooth plate 316, and the reciprocating tooth plate 316 drives the L-shaped frame 326 and the extrusion boss 329 to move in the direction away from the transmission cylinder 103. When the half-tooth cylinder 325 is not meshed with the reciprocating tooth plate 316, the extrusion boss 329 will begin to reset and knock the compressed boss 334 under the action of the vibration spring 305, and the compressed boss 334 drives the vibration cover 331 to start vibrating at the front end inside the feed hopper 112, thereby reducing the phenomenon of salt accumulation inside the feed hopper 112.At the same time, the higher the height of the transmission cylinder 103 is lifted, the more teeth of the intermediate gear cylinder 209 mesh with the driven teeth 308, and the U-shaped plate 307 drives the baffle plate 309 to move toward the transmission cylinder 103. Under the action of the vibration spring 305, the reciprocating gear plate 316 is more positioned toward the transmission cylinder 103, so that the number of teeth of the reciprocating gear plate 316 meshing with the half gear cylinder 325 increases, and the distance that the extrusion boss 329 strikes the compressed boss 334 under the action of the vibration spring 305 also begins to increase, and the amplitude of the vibration of the salt material by the vibration cover 331 also begins to increase, thereby reducing the problem of salt material accumulation inside the feed hopper 112. Among them, the higher the height of the transmission cylinder 103 is lifted, the closer the vibration cover 331 is to the feed hopper 112 The greater the amplitude of vibration, the further the phenomenon of salt accumulation in the feed hopper 112 is reduced. At the same time, the L-shaped frame 326 will drive the reciprocating slide 401 and the reciprocating rod 402 to reciprocate. At this time, the stirring blade 403 can break up the salt in the process of reciprocating in the feed hopper 112, thereby avoiding the phenomenon of salt being blocked in the feed hopper 112. At the same time, during the reciprocating movement of the reciprocating slide 401, the driven gear cylinder 406 will mesh with the active gear plate 408. At this time, the sixth bevel gear 407 and the fifth bevel gear 404 will mesh with each other and rotate the reciprocating rod 402 and the stirring blade 403, thereby allowing the salt in the feed hopper 112 to be efficiently broken up, further reducing the phenomenon of blockage in the feed hopper 112.
