Description

Technical Field

[0001] This invention relates to a proportional reduction technology, specifically a proportional reduction device for materials. Background Technology

[0002] Sample reduction is the process of dividing a sample that has been crushed to a certain particle diameter into several samples with equal reliability, or reducing the original sample before processing or crushing, according to certain requirements.

[0003] In existing technologies, when reducing materials, the reduction ratio of the equipment is fixed, and it can only reduce materials of the corresponding ratio, which is very limiting. When users need to reduce materials of different ratios, they need to disassemble and reassemble the reduction tank, which is complicated and time-consuming. Moreover, the reduction tank may be damaged during disassembly and assembly, affecting the accuracy of subsequent reduction operations. The material entering the feed tank may clump due to its high humidity. Clumped material cannot be accurately reduced during the reduction operation, affecting the reduction accuracy. Furthermore, when the flattening baffle is pulled to one side, the bottom of the feed tank gradually opens, and the material inside the feed tank flows to the side where the material falls. During the flow, some reduction ports may become blocked, making the material flow uneven.

[0004] To address the aforementioned technical problems, this application proposes a solution. Summary of the Invention

[0005] The purpose of this invention is to allow the material after being divided inside the dividing tank to be discharged in a user-defined direction by adjusting the movable baffle. The dividing ratio of the dividing tank can be adjusted by the user, making the adjustment more convenient and eliminating the need for positioning and disassembly of the dividing tank, thus avoiding damage to the dividing tank and ensuring the accuracy of the dividing process. The filter plate reduces the impact of material agglomeration on the dividing accuracy by screening the material, and the partition plate evenly divides the material inside the feed tank, preventing uneven flow distribution due to blockage of the dividing port when the material flows downward. This invention solves the problems of inflexible adjustment of the dividing ratio of the dividing tank, time-consuming adjustment, and easy damage to equipment and errors caused by material agglomeration and blockage during discharge.

[0026] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1:

[0028] Please see Figure 1-6As shown, a proportional reduction device for materials includes a reduction groove, a right reduction port 1 installed on one side of the lower surface of the reduction groove, and a left reduction port 5 installed on the other side of the lower surface of the reduction groove. A vibration motor 4 is installed on the outer wall of the reduction groove corresponding to the positions of the right reduction port 1 and the left reduction port 5. A feed groove 7 is installed on the upper surface of the reduction groove, and a vibration motor 6 is installed on one side of the outer wall of the feed groove 7. The reduction groove consists of eleven evenly distributed reduction grooves 21. A fitting groove 23 is opened on one side of the outer wall of the reduction groove 21, and a fitting strip 25 is integrally formed on the other side of the outer wall of the reduction groove 21 corresponding to the position of the fitting groove 23. This allows adjacent reduction grooves 21 to be fitted into the fitting groove 23 on the adjacent reduction groove 21 through the fitting strip 25 on one side. The location is defined as follows: The inner wall of the shrinking trough 21 has integrally formed feeding ramps 26 on both sides. The feeding ramps 26 on both sides of the inner wall of the shrinking trough 21 converge towards the center, causing the material inside the shrinking trough 21 to gather towards the center under the action of the feeding ramps 26. The lower end of the feeding ramps 26 is rotatably connected to a movable baffle 28 via a rotating shaft. A fitting groove 27 is provided at the docking position of the feeding ramps 26 and the movable baffle 28. Discharge ports 24 are provided on both sides of the outer wall of the shrinking trough 21, allowing the customer to select the direction of discharge for the shrunken material inside the shrinking trough 21. A connecting groove is provided at the upper end of the movable baffle 28 corresponding to the middle position of the fitting groove 27. A connecting groove is installed in the connecting groove corresponding to the position of the rotating shaft. A transmission wheel is installed on the outer side of the reduced groove 21, with support frames 211 installed on both sides corresponding to the positions of the transmission wheel. The inner side of the support frame 211 is rotatably connected to the transmission wheel teeth 212 via a rotating shaft. The transmission wheel teeth 212 and the transmission wheel are connected by a transmission belt 210. A support frame 22 is installed on the outer side of the reduced groove 21 near the lower part of the support frame 211. A sliding groove is opened in the middle of the outer side of the support frame 22. A gear frame 213 is slidably connected inside the sliding groove. A meshing gear 214 is rotatably connected inside the gear frame 213 via a rotating shaft. A planar spiral spring is provided on the inner side of the gear frame 213 corresponding to the position of the meshing gear 214. One end of the planar spiral spring is connected to the meshing gear 214, and the other end is installed on the support frame. On the inner wall of the support frame 22, limit strips 217 are integrally formed on both sides of the outer wall of the gear frame 213 corresponding to both sides of the support frame 22. The limit strips 217 prevent the gear frame 213 from shifting position when sliding inside the support frame 22. A connecting frame 216 is slidably connected to the lower end of the support frame 22. Adjusting racks 215 are integrally formed on both sides of the upper surface of the connecting frame 216. A first switch 218 is installed on the upper part of the outer wall of the support frame 22 near the gear frame 213. The first switch 218 is powered by an external power source and is electrically connected to a energized spring 225 to control the power supply to the energized spring 225. A second switch 219 is installed on the outer wall of the support frame 22 below the first switch 218.The second switch 219 is powered by an external power source and is connected to an electromagnet located at the position of the movable baffle 28, controlling the power supply to the electromagnet. An adjusting push rod 220 is installed on the lower inner surface of the support frame 22 at the position corresponding to the gear frame 213, allowing adjustment of the position of the gear frame 213. Electromagnets are installed on both sides of the lower inner surface of the shrinking main groove 21 at the positions corresponding to the movable baffle 28. An adsorption iron block is installed at the lower end of the movable baffle 28. A limiting groove 29 is formed on the lower inner surface near the movable baffle 28. A steering rod 222 is rotatably connected to the upper inner wall of the limiting groove 29. A limiting baffle 221 is slidably connected inside the limiting groove 29. An electric spring 225 is installed on the lower inner surface of the limiting groove 29. A connecting plate 224 is installed on the upper end of the electric spring 225. The limiting baffle 221 and the connecting plate 224 are connected by a traction rope 223. The traction rope 223 passes upward around the steering rod 222 and then connects downward to the lower end of the limiting baffle 221.

[0029] In the existing technology, when the reduction equipment performs the reduction operation on the processed material, the reduction ratio of the equipment is fixed and it can only perform the reduction operation of the corresponding ratio of the material, which is very limited. When users need to reduce the material by different ratios, they need to disassemble and reassemble the reduction tank, which is complicated and time-consuming. Moreover, the reduction tank may be damaged during the disassembly and reassembly process, affecting the accuracy of subsequent reduction operations.

[0030] Before performing the reduction operation, the user can adjust the orientation of the eleven reduction slots 21 within the reduction groove. The user pulls the connecting frame 216 outwards, causing the adjusting rack 215 on the connecting frame 216 to engage with the meshing gear 214. After the switch at the lower end of the support frame 22 on one side of the reduction slot 21 is activated, the adjusting push rod 220 installed inside the corresponding support frame 22 is extended. During the extension process, the gear frame 213 slides within the support frame 22. During this sliding process, the gear frame 213 is restricted by the limiting strip 217 and remains perpendicular to the support frame 22. As the gear frame 213 slides upwards... During the process, the electromagnet is sequentially pressed against the second switch 219 and the first switch 218 installed on the support frame 22. The second switch 219 closes after being pressed, supplying power to the electromagnet. The first switch 218 activates after being pressed, supplying power to the energized spring 225 after a set time is reached. When the adjusting push rod 220 extends to its maximum length, the engaging gear 214 inside the gear frame 213 engages with the transmission wheel gear 212. As the engaging gear 214 moves upward, it rotates via the adjusting rack 215, tightening the planar spiral spring. Simultaneously with the engaging gear 214 and the transmission wheel gear 212, the engaging gear... Wheel 214 separates from adjusting rack 215, causing transmission wheel gear 212 to rotate under the drive of planar spiral spring. During the rotation of transmission wheel gear 212, the transmission belt 210 drives the movable baffle 28 to rotate at an angle. When the lower end of the movable baffle 28 rotates to the position of the electromagnet, the electromagnet attracts the adsorption iron block at the lower end of the movable baffle 28, thus limiting the position of the movable baffle 28. After a set time, the energized spring 225 is energized and contracts, causing the connecting plate 224 to slide downward, causing the traction rope 223 to pull the limiting baffle 221 upward, thus limiting the downward sliding of the movable baffle 28. The user lowers the support frame 22. When the switch at the end is toggled, the touch sensor located at the lower end of the support frame 22 detects a signal. After the shrinkage trough 21 that receives the touch signal completes its adjustment, the adjustment push rod 220 automatically extends in the opposite direction for the shrinkage trough 21 that does not receive the touch signal. By adjusting the movable baffle 28, the material that has been shrunk inside the shrinkage trough 21 can be discharged in the direction defined by the user. The shrinkage ratio of the shrinkage trough 21 can be adjusted by the user, making the adjustment more convenient. There is no need to perform positioning and disassembly operations on the shrinkage trough 21, so as not to damage the shrinkage trough 21 or adversely affect the accuracy of the shrinkage.

[0031] Example 2:

[0032] Please see Figure 1 and Figure 7-8As shown, a leveling baffle 31 is slidably connected to the lower end of the feed trough 7. The leveling baffle 31 blocks the lower end of the feed trough 7, so that the material inside the feed trough 7 gradually tends to a uniform state through vibration under the action of the vibrating motor 6. A telescopic cylinder 32 is installed on one side of the outer wall of the leveling baffle 31. The telescopic cylinder 32 is installed on the upper surface of the shrinking trough, and the output end of the telescopic cylinder 32 is connected to the leveling baffle 31. A filter plate 33 is installed on the upper side of the inner wall of the feed trough 7. The filter plate 33 can screen out large particles in the material to prevent affecting the shrinking accuracy. Ten insertion slots 38 are opened on one side of the outer wall of the feed trough 7 and the filter plate 33. A partition plate 34 is installed on one side of the upper surface of the filter plate 33. A winding wheel 35 is rotatably connected to the upper surface of the filter plate 33 corresponding to the position of the insertion slot 38 through a bracket. An external gear is integrally formed on one side of the outer wall of the winding wheel 35. A fitting groove 36 is provided on the upper surface of the filter plate 33 at the position corresponding to the external gear. The external gear is fitted with the drive rack 37 through the fitting groove 36. A fitting groove 4 39 is provided at the middle position of both sides of the inner side wall of the insertion groove 38. A sealing plate is slidably connected inside the fitting groove 4 39. The sealing plate slides inside the fitting groove 4 39 and has the same filter holes as the filter plate 33. Rotary connectors are provided at both ends of the sealing plate. Adjacent sealing plates can be rotatably connected together through the rotary connectors. A fitting tooth is provided on one side of the outer side wall of the sealing plate. The fitting tooth is fitted with the drive rack 37, so that the sealing plate can drive the drive rack 37 to move its position when sliding. A drive rack 37 is slidably connected inside the fitting groove 4 39 at the position corresponding to the fitting tooth. A fitting plate 310 is integrally formed on both sides of the outer side wall of the partition plate 34 at the position corresponding to the fitting groove 4 39.

[0033] In the prior art, the material entering the feed trough 7 may clump together due to high humidity. When the clumped material is shrunk, it is impossible to shrunk the material accurately, which affects the shrunk accuracy. In addition, when the flattening baffle 31 is pulled to one side, the bottom of the feed trough 7 gradually opens, and the material inside the feed trough 7 flows to the side where the material falls. During the flow, some shrunk openings become blocked, which makes the flow direction of the material easy to be unevenly distributed.

[0034] The filter plate 33 is installed inside the feed trough 7. Under the action of the vibrating motor 6, it can screen the material entering the feed trough 7, allowing the material that has clumped due to moisture to be screened out. Some loosely clumped material can be dispersed under the action of vibration. The material gradually becomes more uniform under the action of vibration inside the feed trough 7. After becoming more uniform, ten partition plates 34 installed on one side of the feed trough 7 are inserted inward. The partition plates 34 slide along the insertion groove 38. During the separation process, the material inside the feed trough 7 is always evenly distributed inside the feed trough 7 under the action of the vibrating motor 6. The partition plates 34 push the sealing plate to slide to one side. During the sliding process, the sealing plate drives the drive rack 37 to slide to one side through the interlocking teeth on one side. When the drive rack 37 slides to one side, it drives the collection rack 37 to slide to one side. The external gear connected to the reel 35 rotates, causing the take-up reel 35 to rotate and perform a take-up operation on the sealing plate. The sealing plate ensures that the insertion slot 38 position does not affect the filtration operation of the filter plate 33. After the partition plate 34 is fully inserted, it divides the inside of the feed trough 7 into eleven spaces of equal size. The material distribution in each space is the same. After the flattening baffle 31 is pulled out under the action of the telescopic cylinder 32, the downward flowing material will only flow downward into the corresponding shrinkage trough due to the separation of the partition plate 34. The interference between them is reduced, and there will be no uneven distribution. The screening of the material by the filter plate 33 reduces the impact of material agglomeration on the shrinkage accuracy. The uniform separation of the material inside the feed trough 7 by the partition plate 34 ensures that the material will not have uneven flow distribution due to blockage of the shrinkage port when flowing downward.

[0035] In use, the filter plate 33 is installed inside the feed trough 7. Under the action of the second vibrating motor 6, the material entering the feed trough 7 can be screened, allowing materials that are clumped due to moisture to be screened out. Some loosely clumped material clumps can be dispersed under the action of vibration. The material gradually becomes more even under the action of vibration inside the feed trough 7. After it becomes more even, ten partition plates 34 installed on one side of the feed trough 7 are inserted inward. The partition plates 34 slide along the insertion groove 38. During the separation process, the material inside the feed trough 7 is always evenly distributed inside the feed trough 7 under the action of the second vibrating motor 6. The partition plates 34 push the sealing plate to slide to one side. In the process, the sealing plate drives the drive rack 37 to slide to one side through the interlocking teeth on one side. When the drive rack 37 slides to one side, it drives the external gear connected to the winding wheel 35 to rotate, causing the winding wheel 35 to rotate and perform a winding operation on the sealing plate. The sealing plate ensures that the insertion slot 38 position will not affect the filtration operation of the filter plate 33. After the partition plate 34 is fully inserted, it divides the inside of the feed trough 7 into eleven spaces of equal size. The material distribution in each space is the same. After the flattening baffle 31 is pulled out under the action of the telescopic cylinder 32, the downward flowing material will only flow downward into the corresponding shrinkage slot due to the separation of the partition plate 34. The interference between them is reduced and there will be no uneven distribution.

[0036] Before performing the reduction operation, the user can adjust the orientation of the eleven reduction slots 21 in the reduction groove. The user pulls the connecting frame 216 outward, so that the adjusting rack 215 on the connecting frame 216 engages with the engaging gear 214. After the switch at the lower end of the support frame 22 on one side of the reduction slot 21 is turned, the adjusting push rod 220 installed inside the support frame 22 is activated to extend. During the extension, the gear frame 213 is pushed to slide within the support frame 22. During the sliding process, the gear frame 213 is restricted by the limiting strip 217. Always perpendicular to the support frame 22, the gear frame 213 slides upwards, sequentially pressing against the second switch 219 and the first switch 218 installed on the support frame 22. The second switch 219, when pressed, closes and supplies power to the electromagnet, while the first switch 218, when pressed, activates and supplies power to the energized spring 225 after a set time is reached. When the adjusting push rod 220 extends to its maximum length, the engaging gear 214 inside the gear frame 213 engages with the transmission wheel teeth 212. The engaging gear 214... During the upward movement, the rack 215 rotates, tightening the planar spiral spring. Simultaneously, the engaging gear 214 engages with the transmission wheel gear 212, while the engaging gear 214 disengages from the rack 215, causing the transmission wheel gear 212 to rotate under the influence of the planar spiral spring. During this rotation, the transmission wheel gear 212 drives the movable baffle 28 to rotate via the transmission belt 210. When the lower end of the movable baffle 28 rotates to the position of the electromagnet, the electromagnet attracts the adsorption iron block at the lower end of the movable baffle 28, causing the movable baffle 28 to move upwards. The position of the movable baffle 28 is limited. After a set time is reached, the energized spring 225 is energized and contracts, causing the connecting plate 224 to slide downward. This causes the traction rope 223 to pull the limiting baffle 221 upward, thus limiting the downward sliding of the movable baffle 28. When the user flips the switch at the lower end of the support frame 22, the touch sensor at the lower end of the support frame 22 detects a signal. After the reduction slot 21 that receives the touch signal completes the adjustment, the adjustment push rod 220 automatically extends in the opposite direction for the reduction slot 21 that does not receive the touch signal.

[0037] After the reduction operation is completed, the user flips the first reset switch under one of the support frames 22 to disconnect the circuit switch. The electromagnet and the energized spring 225 are de-energized and do not receive external power. The movable baffle 28 is unobstructed and automatically swings downward under the action of gravity. The adjusting push rod 220 retracts after receiving the power-off signal. When the adjusting push rod 220 retracts and squeezes the first switch 218 and the second switch 219, the operation of touching the switch is not affected because the power is disconnected. After the adjusting push rod 220 is shortened to its maximum length, it touches the second reset switch under the inner side of the support frame 22 to close the circuit switch. The first switch 218 and the second switch 219 can be extended by adjusting the push rod 220 after being squeezed again.
