Description

Technical Field

[0001] This utility model relates to the field of dehydrated radish powdering technology, specifically a raw material powdering device. Background Technology

[0002] Dehydrated radish is in block form and has a relatively hard texture. During the preparation of seasoning powders, sauces, and fillings for baked goods, the dehydrated radish needs to be crushed. This makes the crushed dehydrated radish easier to marinate and allows for more flexible combinations with other ingredients. Workers poured a large amount of dehydrated radish into the feed inlet of the device. Although this saved the number of feedings, it required workers to stand next to the feed inlet and manually clear any blockages until all the dehydrated radishes had entered the device. This resulted in varying intervals between the time it took for the dehydrated radishes to enter the device, and an excessive feed amount could cause the dehydrated radish to be discharged without being completely crushed.

The first rotating shafts extend through the left side wall of the housing to the right side wall inside the housing. Both first rotating shafts are provided with spur gears near their left ends. The housing is provided with a crushing disc assembly around the outer ring of the first rotating shafts. The feeding assembly includes a second rotating shaft at the top of the first rotating shaft and a three-groove rotating block at the right end of the second rotating shaft corresponding to the top of the housing. The outer ring of the three-groove rotating block is provided with a material distribution box, and the outer ring of the second rotating shaft is provided with a first bevel gear near the left end. The top of the first bevel gear is provided with a second bevel gear, the top of the second bevel gear is provided with a second synchronous pulley, and the middle of the second synchronous pulley is provided with an L-shaped rod. The top right end of the L-shaped rod is provided with a feeding hopper.

[0005] Preferably, a handle is provided at the middle of the right side of the front door, and the handle is welded and fixed to the front door. The front door is rotatably connected to the housing at the corresponding position. The support plate is welded and fixed to the housing. The top of the housing is welded and fixed to the material distribution box.

[0006] In this utility model, a handle is welded and fixed to the front door. The rotating connection allows the front door to be opened to remove and empty the material receiving box inside the housing, which facilitates cleaning of the inside of the housing. The welding and fixing increases the overall structural stability of the support plate and the housing.

[0007] Preferably, a fixing frame is provided at the top of the support plate corresponding to the rotary motor, and the rotary motor is snapped and fixed to the fixing frame. The left and right ends of the coupling are respectively connected and fixed to the output shaft of the rotary motor and the front first rotating shaft by screws. The outer ring of the front first rotating shaft and the outer ring of the second rotating shaft are both provided with a first synchronous pulley at the same vertical position, and the outer ring of the two first synchronous pulleys is fitted with a first synchronous belt.

[0008] In this utility model, the bottom of the fixed frame is welded and fixed to the support frame. The support frame and the fixed frame are set to provide stable support for the rotary motor. The coupling is set so that the output shaft of the rotary motor rotates continuously, driving the first rotating shaft to rotate continuously. The rotation of the first rotating shaft causes the corresponding first synchronous pulley to rotate continuously. The bottom first synchronous pulley rotates in the same direction as the top first synchronous pulley through the first synchronous belt.

[0009] Preferably, the two spur gears mesh with each other, and the two first rotating shafts are rotatably connected to the corresponding positions on the left side wall of the housing. The crushing disc assembly includes a plurality of crushing discs arranged horizontally at equal intervals. The outer rings of the two first rotating shafts are welded and fixed to the corresponding crushing discs, and the plurality of crushing discs at the front end and the plurality of crushing discs at the rear end are placed at intervals.

[0010] In this invention, the two first rotating shafts mesh with each other to rotate in opposite directions. Welding and fixing enable the two first rotating shafts to drive the corresponding crushing discs on the outer ring to rotate in opposite directions. The outer ring of the crushing discs is provided with a number of protruding teeth at equal intervals, and the teeth on each crushing disc are staggered and placed in conjunction with the corresponding crushing discs on the two first rotating shafts at intervals, so as to crush the dehydrated dried radish that falls onto the crushing disc group.

[0011] Preferably, the second rotating shaft passes through the corresponding part of the material distribution box and is welded and fixed to the three-slot rotating block. The first bevel gear and the second rotating shaft are integrally formed. The first bevel gear and the second bevel gear mesh with each other. A connecting rod is provided between the second bevel gear and the second synchronous pulley. The second synchronous pulley, the connecting rod and the second bevel gear are integrally formed.

[0012] In this invention, turning on the rotary motor control switch causes the two first synchronous pulleys to rotate synchronously. The rotation of the top first synchronous pulley causes the three-slot rotating blocks to rotate synchronously. Three equally spaced slots are circumferentially opened on the three-slot rotating blocks to facilitate the batch feeding of dehydrated radish slices into the slots. The top of the dispensing box is truncated cone-shaped, and the bottom of the dispensing box is welded and fixed to the corresponding position on the shell. The bottom of the dispensing box corresponds to the rectangular opening on the top of the shell. The dehydrated radish slices fall from the top of the dispensing box into the corresponding slots on the three-slot rotating blocks, where they are rotated by the second rotating shaft. When the slot rotates to the position corresponding to the rectangular opening, the dehydrated radish slices are released from the slot. The radish chips detach from the inside and fall to the top of the crushing disc assembly. The distance between the slot and the other two slots is the same, which allows the three-slot rotating blocks to detach from the previous batch of dehydrated radish chips. The next batch of dehydrated radish chips enters the corresponding slot. When the next batch of dehydrated radish chips detaches from the slot, the previous batch of dehydrated radish chips is crushed and separated from the crushing disc assembly. This ensures that the interval between each batch of dehydrated radish chips entering the shell is the same, and the overall size of each batch of dehydrated radish chips is consistent with the slot. This avoids uneven time intervals between the dehydrated radish chips entering the crushing disc assembly and large differences in the feed amount, thus reducing the size difference of the dehydrated radish chips after being crushed by the crushing disc assembly.

[0013] Preferably, the second synchronous pulley is rotatably connected to the bottom of the L-shaped rod, the top right end of the L-shaped rod is welded and fixed to the feed hopper, the top of the distribution box is provided with a third synchronous pulley, the outer ring of the third synchronous pulley and the second synchronous pulley are fitted with a second synchronous belt, the upper and lower ends of the third synchronous pulley are provided with bearings, and the upper and lower ends of the inner ring of the third synchronous pulley are welded and fixed to the corresponding positions of the inner rings of the two bearings.

[0014] In this invention, the rotation of the second rotating shaft drives the first bevel gear to rotate synchronously. The first bevel gear meshes with the second bevel gear, which has a connecting rod and a second synchronous pulley, so that when the first bevel gear rotates, the second bevel gear and the second synchronous pulley rotate synchronously. An L-shaped rod is provided to provide stable support for the second synchronous pulley. The rotation of the second synchronous pulley drives the third synchronous pulley inside the second synchronous belt to rotate continuously. The bottom of the outer ring of the bottom bearing is welded and fixed to the top of the distribution box, and the top of the outer ring of the top bearing is welded and fixed to the bottom of the feed hopper. When the third synchronous pulley rotates, it drives the inner rings of the two bearings to rotate synchronously. A support frame is provided outside the feed hopper, and the bottom of the support frame is welded and fixed to the corresponding part of the shell. The support frame is provided to provide stable support for the feed hopper.

[0015] Preferably, the inner wall of the inner ring of the third synchronous pulley is provided with a rotating rod, the rotating rod is adapted to the inclination of the corresponding part of the inner wall of the feed hopper, and a slanted round rod group is provided on one side of the rotating rod.

[0016] In this invention, the rotating rod is welded and fixed to the inner ring of the third synchronous pulley at the corresponding position. The third synchronous pulley drives the rotating rod to rotate continuously along the inner ring of the bearing. The top of the rotating rod is at the same height as the top of the feed hopper, and the bottom of the rotating rod is at the same height as the bottom of the third synchronous pulley. The oblique round rod assembly is welded and fixed to the rotating rod at the corresponding position. The oblique round rod assembly rotates synchronously with the rotating rod. The continuous rotation of the rotating rod and the oblique round rod assembly prevents several blocky pieces of dehydrated radish from clogging inside the feed hopper, allowing the dehydrated radish to fall into the slot inside the distribution box. It cooperates with the continuously rotating second rotating shaft to continuously feed the dehydrated radish inside the feed hopper in batches.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model sets up a rotating rod with a slanted round rod assembly and welds it to the inner ring of the third synchronous belt pulley. When the third synchronous belt pulley rotates, it drives the inside of the feeding hopper to rotate continuously, which facilitates the rotation and feeding of the dehydrated radish inside the feeding hopper. The top first synchronous belt pulley is coaxially connected to the three-groove rotating block to facilitate the batch feeding of the continuously feeding dehydrated radish, so as to achieve a consistent interval between the dehydrated radish entering the device and avoid the situation where the size difference after crushing is large due to excessive or insufficient feeding. 2. This utility model uses a rotary motor to drive two first synchronous pulleys and a first bevel gear to rotate synchronously, and a second bevel gear to rotate synchronously with a second synchronous belt, which in turn drives the second synchronous pulley and a third synchronous pulley to rotate continuously. This allows the crushing discs to rotate in opposite directions to crush the dehydrated radish, while the rotating rod and the three-groove rotating block rotate synchronously inside the feeding hopper and the distributing box, respectively. This enables the feeding, distributing, and crushing processes to be carried out simultaneously. A front door is provided at the front end of the shell to facilitate the removal and emptying of the receiving box inside the shell. Attached Figure Description

The crushing assembly 2 includes a support plate 200 located near the middle of the left side wall of the housing 1, a rotary motor 20 located at the top of the support plate 200, and a coupling 21 located at the right end of the output shaft of the rotary motor 20. The right end of the coupling 21 has two symmetrically arranged first rotating shafts 22, which extend through the left side wall of the housing 1 to the right side wall inside the housing 1. 22 is provided near the left end of each of the two shafts 22. Inside the housing 1, there is a crushing disc assembly 24 on the outer ring of the first rotating shaft 22. The top of the support plate 200 is provided with a fixed frame corresponding to the rotary motor 20. The rotary motor 20 is snapped and fixed to the fixed frame. The left and right ends of the coupling 21 are respectively connected and fixed to the output shaft of the rotary motor 20 and the front first rotating shaft 22 by screws. The outer ring of the front first rotating shaft 22 and the outer ring of the second rotating shaft 30 are provided with first synchronous pulleys 23 at the same vertical position. The outer rings of the two first synchronous pulleys 23 are fitted with first synchronous belts 230.

[0022] In this utility model, the bottom of the fixed frame is welded and fixed to the support frame. The support frame and the fixed frame are set to provide stable support for the rotary motor 20. The coupling 21 is set so that the output shaft of the rotary motor 20 rotates continuously, driving the first rotating shaft 22 to rotate continuously. The rotation of the first rotating shaft 22 causes the corresponding first synchronous pulley 23 to rotate continuously. The bottom first synchronous pulley 23 rotates in the same direction as the top first synchronous pulley 23 through the first synchronous belt 230.

[0023] Among them, two spur gears 220 mesh with each other, and two first rotating shafts 22 are rotatably connected to the corresponding left side wall of the housing 1. The crushing disc group 24 includes several crushing discs arranged horizontally at equal intervals. The outer rings of the two first rotating shafts 22 are welded and fixed to the corresponding crushing discs. Several crushing discs at the front end and several crushing discs at the rear end are placed at intervals.

[0024] In this invention, the two first rotating shafts 22 are meshed together, causing them to rotate in opposite directions. The welding and fixing of the two first rotating shafts 22 respectively drive a number of crushing discs on their corresponding outer rings to rotate in opposite directions. The outer ring of the crushing discs is provided with a number of protruding teeth at equal intervals, and the teeth on each crushing disc are staggered and placed in conjunction with the corresponding crushing discs on the two first rotating shafts 22, thereby crushing the dehydrated dried radish that falls onto the crushing disc group 24.

[0025] Specifically, the feeding assembly 3 includes a second rotating shaft 30 located at the top of the first rotating shaft 22 and a three-slot rotating block 300 located at the right end of the second rotating shaft 30 corresponding to the top of the housing 1. The outer ring of the three-slot rotating block 300 is provided with a material distribution box, and the outer ring of the second rotating shaft 30 is provided with a first bevel gear 31 near the left end. The top of the first bevel gear 31 is provided with a second bevel gear 320, and the top of the second bevel gear 320 is provided with a second synchronous pulley 33. The second synchronous pulley 33 is provided with an L-shaped rod 32 in the middle, and the top right end of the L-shaped rod 32 is provided with a feeding hopper 36. The second rotating shaft 30 passes through the material distribution box and is welded and fixed to the three-slot rotating block 300. The first bevel gear 31 and the second rotating shaft 30 are integrally formed. The first bevel gear 31 and the second bevel gear 320 mesh with each other. The second bevel gear 320 and the second synchronous pulley 33 are provided with a connecting rod in the middle, and the second synchronous pulley 33, the connecting rod, and the second bevel gear 320 are integrally formed.

[0026] In this invention, turning on the control switch of the rotary motor 20 causes the two first synchronous pulleys 23 to rotate synchronously. The rotation of the top first synchronous pulley 23 causes the three-slot rotating block 300 to rotate synchronously. The three-slot rotating block 300 has three equally spaced slots on its ring shape, facilitating the batch feeding of dehydrated radish into the slots. The top of the dispensing box is shaped like a frustum, and the bottom of the dispensing box is welded and fixed to the corresponding position of the housing 1. The bottom of the dispensing box corresponds to the rectangular opening 12 on the top of the housing 1. The dehydrated radish falls from the top of the dispensing box into the corresponding slot on the three-slot rotating block 300, where it is rotated by the second rotating shaft 30. When the slot rotates to the position corresponding to the rectangular opening 12, the dehydrated radish... The dried radish leaves the slot and falls to the top of the crushing disc group 24. The slot is equidistant from the other two slots, allowing the three-slot rotating block 300 to separate from the previous batch of dehydrated dried radish. The next batch of dehydrated dried radish enters the corresponding slot. When the next batch of dehydrated dried radish leaves the slot, the previous batch of dehydrated dried radish is crushed and separated from the crushing disc group 24. This ensures that the interval between each batch of dehydrated dried radish entering the shell 1 is the same, and the overall size of each batch of dehydrated dried radish is consistent with the slot size. This avoids uneven time intervals between batches of dehydrated dried radish entering the crushing disc group 24 and large differences in feed volume, thus reducing the size difference of the dehydrated dried radish after being crushed by the crushing disc group 24.

[0027] Secondly, the second synchronous pulley 33 is rotatably connected to the bottom of the L-shaped rod 32, and the top right end of the L-shaped rod 32 is welded and fixed to the feed hopper 36.

[0028] In this invention, the rotation of the second rotating shaft 30 drives the first bevel gear 31 to rotate synchronously. The first bevel gear 31 meshes with the second bevel gear 320, which has a connecting rod and a second synchronous pulley 33. This allows the second bevel gear 320 and the second synchronous pulley 33 to rotate synchronously when the first bevel gear 31 rotates. The L-shaped rod 32 is provided to provide stable support for the second synchronous pulley 33. The rotation of the second synchronous pulley 33 drives the third synchronous pulley 331 inside the second synchronous belt 330 to rotate continuously. The bottom of the outer ring of the bottom bearing 34 is welded and fixed to the top of the distribution box, and the top of the outer ring of the top bearing 34 is welded and fixed to the bottom of the feed hopper 36. When the third synchronous pulley 331 rotates, it drives the inner rings of the two bearings 34 to rotate synchronously. A support frame is provided outside the feed hopper 36. The bottom of the support frame is welded and fixed to the corresponding position of the housing 1. The support frame is provided to provide stable support for the feed hopper 36.

[0029] In addition, the inner wall of the inner ring of the third synchronous pulley 331 is provided with a rotating rod 35, the rotating rod 35 is adapted to the inclination of the corresponding part of the inner wall of the feed hopper 36, and a slanted round rod group 350 is provided on one side of the rotating rod 35.

[0030] In this invention, the rotating rod 35 is welded and fixed to the inner ring of the third synchronous pulley 331.

The top of the rotating rod 35 is at the same height as the top of the feed hopper 36, and the bottom of the rotating rod 35 is at the same height as the bottom of the third synchronous pulley 331. The oblique round rod assembly 350 is welded and fixed to the rotating rod 35 at the corresponding position. The oblique round rod assembly 350 rotates synchronously with the rotating rod 35. The continuous rotation of the rotating rod 35 and the oblique round rod assembly 350 prevents several blocky pieces of dehydrated radish from clogging inside the feed hopper 36, allowing the dehydrated radish to fall into the slot inside the distribution box. It cooperates with the continuously rotating second rotating shaft 30 to continuously feed the dehydrated radish inside the feed hopper 36 in batches.

The front door 10 is rotatably connected to the housing 1 at the corresponding position. The support plate 200 is welded and fixed to the housing 1, and the top of the housing 1 is welded and fixed to the dispensing box.

[0032] In this utility model, a handle is welded and fixed to the front door 10.

After installation, turn on the external control switch of the rotary motor 20 and put several blocks of dehydrated radish into the feed hopper 36. The dehydrated radish at the bottom enters the slot of the three-slot rotating block 300 inside the distribution box along the inner ring of the bearing 34. The slots on the three-slot rotating block 300 are distributed in a ring with equal spacing, so that the falling interval of the dehydrated radish inside the slot is consistent, and the fixed capacity of the slot also avoids the situation of excessive or insufficient feeding. The second rotating shaft 30 drives the three-slot rotating block 300 to rotate. When the slot rotates to the rectangular opening 12 at the top of the shell 1, the dehydrated radish inside the slot... The radish falls to the top of the crushing disc. With the cooperation of the opposing spur gears 220, the teeth on several opposing crushing discs crush the falling dehydrated radish. The crushed dehydrated radish falls into the receiving box 11.
