Description

Technical Field

[0001] The invention relates to the technical field of spice crushing, in particular to a food pickling spice crushing device. Background Art

[0002] Crushing spices during food pickling can make it easier to release the volatile components in the spices, and the finely crushed spices can penetrate into the ingredients more quickly, speeding up the pickling process.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, a food pickling spice crushing device includes a base 1, a swing mechanism 6 is provided on the upper surface of the base 1, a fixed frame 2 that swings back and forth is provided on the swing mechanism 6, a lower hopper 7 is fixedly installed on the rear surface of the fixed frame 2, a collecting frame 5 is detachably installed on the lower surface of the fixed frame 2, a crushing mechanism 3 for crushing spices is provided on the inner side of the fixed frame 2, and the crushing device also includes a return mechanism 4 for re-conveying spices with unqualified crushing diameters to the inside of the crushing mechanism 3 for crushing.

Below the surface ring 323, multiple second crushing knives 321 distributed up and down are staggered from top to bottom. A spline is provided at the bottom end of the output shaft of the first drive motor 324, and a spline groove is provided at the top of the rotating shaft 322. The spline and the spline groove are slidably matched. A return spring is jointly sleeved on the outer side of the rotating shaft 322 and the output shaft of the first drive motor 324. The upper surface of the adjusting curved ring 323 is a curved surface and there is a height difference between the left and right sides. A roller is provided at the end of the auxiliary bracket 325 away from the rotating shaft 322, and the auxiliary bracket 325 is rollingly matched with the upper surface of the adjusting curved ring 323 through the roller.

[0037] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the first crushing member 31 includes two connecting rings 314 distributed up and down and fixedly connected to the inner side of the fixed frame 2, and a fixing ring 313 is rotatably connected to the inner circumference of the connecting ring 314. A loading bucket 312 is fixedly connected to the inner circumference of the two fixing rings 313. The loading bucket 312 is located below the adjusting curved surface ring 323. A plurality of first crushing knives 315 arranged in an offset manner are evenly distributed up and down on the inner circumference of the loading bucket 312. The plurality of first crushing knives 315 correspond to the plurality of second crushing knives 321 one by one and are located below the second crushing knives 321. The first crushing knives 315 on the same horizontal plane are installed in the loading bucket 312 through the same mounting ring, and a gear ring 311 is fixedly connected to the top of the outer circumference of the loading bucket 312.

[0038] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the transmission member 33 includes a mounting bracket 331 fixedly connected to the top of the right side surface of the fixed frame 2, a transmission box 332 is fixedly connected to the lower surface of the fixed frame 2, a transmission shaft 333 is rotatably connected to the right end of the lower surface of the transmission box 332, the transmission shaft 333 is rotatably connected to the mounting bracket 331, a transmission gear plate 334 is fixedly connected to the bottom end of the transmission shaft 333, the transmission gear plate 334 is meshed with the gear ring 311, and the output shaft of the first drive motor 324 passes through the transmission box 332 from top to bottom and is transmission-connected to the transmission shaft 333 through the gear set inside the transmission box 332 (as shown in FIG. Figure 6 as shown).

[0039] During specific use, when the spice crushing starts, the rotating shaft 322 is first driven to rotate by the first driving motor 324, and the transmission shaft 333 is driven to rotate synchronously in the opposite direction on the transmission box 332 through the gear group transmission. The transmission gear plate 334 rotates synchronously with the transmission shaft 333, and the loading barrel 312 is driven to rotate synchronously through the ring gear 311. At this time, the rotating shaft 322 drives the second crushing knife 321 to rotate inside the loading barrel 312, and the loading barrel 312 drives the first crushing knife 315 to rotate in the opposite direction to the second crushing knife 321, and then the spices are quantitatively transported to the inside of the loading barrel 312 through the lower hopper 7. At this time, the spices are crushed by the second crushing knife 321 and the first crushing knife 315.

[0040] At the same time, the rotating shaft 322 drives the auxiliary bracket 325 to rotate in close contact with the upper surface of the adjusting curved surface ring 323 during the rotation process. Since the upper surface of the adjusting curved surface ring 323 is a curved surface and there is a height difference between the left and right sides, when the auxiliary bracket 325 rotates in close contact with the adjusting curved surface ring 323, the roller on the auxiliary bracket 325 can make the auxiliary bracket 325 and the adjusting curved surface ring 323 slide more smoothly. Then, the auxiliary bracket 325 drives the rotating shaft 322 to move up and down as the rotating shaft 322 rotates. When the auxiliary bracket 325 rotates in close contact with the adjusting curved surface ring 323, the roller on the auxiliary bracket 325 can make the auxiliary bracket 325 and the adjusting curved surface ring 323 slide more smoothly. When sliding from the lower part to the higher part of the curved surface of the adjusting curved ring 323, the top end of the rotating shaft 322 slides upward on the spline shaft at the bottom end of the output shaft of the first driving motor 324 and compresses the return spring. Conversely, the elastic force of the return spring and the gravity of the rotating shaft 322 and the second crushing knife 321 make the rotating shaft 322 move downward. In this way, the rotating shaft 322 makes reciprocating movements up and down during the rotation process, driving the second crushing knife 321 to generate an axial cutting force on the spices, so that the spices can be crushed more thoroughly under the action of the multi-directional crushing force.

[0041] like Figure 4 , Figure 8 and Fig. 9 As shown, the material dividing member 34 includes a conical boss 345 rotatably connected to the bottom end of the loading barrel 312, the conical boss 345 is located directly above the collecting frame 5, the bottom end of the conical boss 345 is provided with a planar extension portion, a plurality of screens 344 are detachably mounted on the conical surface of the conical boss 345, a spline shaft is rotatably provided on the upper surface of the conical boss 345, the conical boss 345 is slidably connected to the bottom end of the rotating shaft 322 up and down through the spline shaft, a plurality of scraping strips 341 distributed in a circumferential array are fixedly connected to the bottom end of the spline shaft, the interior of the scraping strip 341 is slidably connected to a sliding plate 342, the top end of the sliding plate 342 passes through the outside of the scraping strip 341 and is hinged with a linkage Rod 343, one end of the linkage rod 343 away from the sliding plate 342 is hinged to the bottom end of the outer circumferential surface of the rotating shaft 322, a limiting slide groove 346 is arranged inside the scraper strip 341, and a slider (not shown in the figure) adapted to the limiting slide groove 346 is arranged on the sliding plate 342, a cleaning brush 347 is fixedly connected to the lower surface of the sliding plate 342, a through groove adapted to the cleaning brush 347 is opened on the lower surface of the scraper strip 341, and the bottom end of the cleaning brush 347 passes through the through groove and fits on the screen 344, and the bottom end of the scraper strip 341 slides against the upper surface of the flat extension part of the bottom end of the conical boss 345, and a material drop groove which passes through from top to bottom is opened on the front side of the upper surface of the conical boss 345.

[0042] During specific use, as the spices are crushed, they fall downward onto the screen 344, and the qualified spices are screened to the bottom through the screen 344 and fall into the inside of the collecting frame 5. Some large-diameter spice particles are screened out and slide downward along the conical surface of the screen 344 to the upper side of the planar extension part of the bottom end of the conical boss 345. During the rotation of the rotating shaft 322, the scraper bar 341 is driven to rotate synchronously, and the large-diameter particles at the bottom end of the conical boss 345 are gathered by the scraper bar 341, and are pushed to the drop port position on the conical boss 345 as the rotating shaft 322 rotates, and fall downward from the drop port.

[0043] At the same time, during the up and down movement of the rotating shaft 322, the bottom end of the rotating shaft 322 moves up and down on the spline shaft at the top of the conical boss 345, and pushes the sliding plate 342 to slide back and forth along the conical surface of the screen 344 on the scraper strip 341 through the linkage rod 343, thereby driving the cleaning brush 347 to perform a reciprocating cleaning action on the screen 344, and some spices stuck on the screen 344 are cleaned off in time to ensure the screening efficiency of the screen 344. At the same time, under the action of the limiting slide groove 346, when the sliding plate 342 slides back and forth on the scraper strip 341, it synchronously cooperates with the sliding block to slide inside the limiting slide groove 346, and the limiting slide groove 346 guides and limits the sliding direction of the sliding plate 342, ensuring that the sliding plate 342 slides stably along the direction of the conical surface of the screen 344 to ensure the cleaning effect of the cleaning brush 347.

[0044] like Figure 1 , Figure 5 , Figure 8 and Fig.10 As shown, the material return mechanism 4 includes a fixed shell 42 fixedly connected to the front side of the fixed frame 2, the fixed shell 42 is internally rotatably connected with a spiral blade shaft 43, the upper side of the outer circumferential surface of the fixed shell 42 is fixed and penetrated by a conveying bucket 44, the lower side of the outer circumferential surface of the fixed shell 42 is fixed and penetrated by a receiving bucket 45, the side of the receiving bucket 45 away from the fixed shell 42 is provided with screening holes, the receiving bucket 45 is located above the collecting frame 5, the top end of the receiving bucket 45 is fixedly connected to the lower surface of the conical boss 345 and is connected to the material drop chute, the top end of the spiral blade shaft 43 penetrates to the upper surface of the fixed shell 42 and is fixedly connected with a pulley 41, the pulley 41 is connected to the output shaft of the first drive motor 324 through a belt, and the conveying bucket 44 is located above the loading barrel 312.

[0045] During specific use, large-diameter spice particles fall downward from the drop port on the conical boss 345, and then fall into the inside of the receiving hopper 45, and roll from the inside of the receiving hopper 45 to the bottom end of the fixed shell 42. In the process of the large-diameter spice particles passing through the receiving hopper 45, the small-diameter particles adhering to the large-diameter spice particles can be screened for the second time through the sieve holes on the receiving hopper 45. The screened small-diameter spice particles fall into the inside of the collecting frame 5 to avoid excessive crushing of the spices. When the first drive motor 324 drives the rotating shaft 322 to rotate, the spiral blade shaft 43 is driven to rotate inside the fixed shell 42 through the belt and pulley 41. At this time, after the large-diameter spice particles enter the bottom end of the fixed shell 42, the spiral blade shaft 43 rotates to transport the large-diameter particles upward, and is re-conveyed to the inside of the loading barrel 312 through the conveying hopper 44 for secondary crushing.

[0046] like Figure 1 and Fig.11 As shown, the swing mechanism 6 includes two left-right symmetrical support platforms 61 fixedly connected to the upper surface of the base 1, a rotating shaft 62 is rotatably connected between the opposite surfaces of the top ends of the two support platforms 61, two left-right symmetrical connecting plates 63 are fixedly connected to the upper surface of the fixed frame 2, the top ends of the connecting plates 63 are fixedly connected to the rotating shaft 62, a convex strip 64 is fixedly connected to the middle circumferential surface of the rotating shaft 62, a second drive motor 66 is fixedly installed on the right support platform 61 through a motor seat, a cam 65 is fixedly connected to the output shaft of the second drive motor 66, the position of the cam 65 corresponds to the position of the convex strip 64, and the cam 65 and the convex strip 64 are slidably matched, and the second drive motor 66 is a large torque low-speed motor.

[0047] During specific use, in the process of crushing the spices, the second drive motor 66 rotates at a low speed, driving the cam 65 to rotate synchronously. When the raised position of the cam 65 passes through the convex strip 64, the cam 65 generates a thrust on the convex strip 64. The convex strip 64 is forced to drive the rotating shaft 62 to deflect on the support platform 61. At this time, the rotating shaft 62 drives the fixed frame 2 to deflect synchronously through the connecting piece 63. Then, in the process of crushing the spices, the loading barrel 312 performs a reciprocating swing in the front and rear directions. The reciprocating swing can make the particles more evenly distributed in the loading barrel 312, avoid local accumulation, and ensure that the particles can fully contact the second crushing knife 321 and the first crushing knife 315; and increase the collision chance between the particles and the second crushing knife 321 and the first crushing knife 315, thereby improving the crushing efficiency; at the same time, the swing can prevent the particles from forming blockage in the loading barrel 312, maintain the smooth flow of feeding, and improve the screening effect.

[0048] like Figure 1-Figure 11As shown, the working principle is: during specific use, the first driving motor 324 first drives the second crushing blade 321 and the first crushing blade 315 to rotate synchronously and in the opposite direction, and then the spices are quantitatively transported to the inside of the loading barrel 312 through the lower hopper 7, and the spices are then crushed. During the crushing process, the second crushing blade 321 moves up and down, generating an axial cutting force on the spices. When the spices are crushed, they fall onto the receiving hopper 45, and the crushed spices are screened by the receiving hopper 45, and the large-diameter spice particles are screened out and pushed into the fixed shell 42, and then transported upward by the spiral blade shaft 43 back to the inside of the loading barrel 312 for secondary crushing. The spices that have passed the crushing fall into the collecting frame 5 below the receiving hopper 45, and the staff collects them regularly.
