Description

Technical Field

[0001] This invention relates to the field of fruit and food testing technology, specifically to an intelligent food testing station. Background Technology

[0002] Food safety plays a vital role in modern life. Errors in food safety can severely harm our health. Dried fruits and vegetables, primarily made from processed fruits and vegetables, require random checks for Aspergillus flavus after processing. Aspergillus flavus has a loose structure, a grayish-green surface, and a colorless or slightly brownish underside. The fungus consists of many complex branched hyphae. Current methods primarily rely on visual inspection of the outer surface of the dried fruits and vegetables. This method only detects the outer surface and cannot detect Aspergillus flavus on the inside. Some dried fruits and vegetables develop Aspergillus flavus from the inside while the outer surface remains intact. In such cases, visual inspection of the outer surface alone cannot detect the Aspergillus flavus on the inside. Therefore, it is necessary to provide an intelligent food testing platform to solve these technical problems. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent food testing station to solve the problem mentioned in the background art, which is that the existing testing methods rely on the human eye to observe the color of the outer surface of dried fruits and vegetables. This method can only detect the outer surface of dried fruits and vegetables, but cannot detect aflatoxin on the inside. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an intelligent food testing station, comprising an outer frame, a pusher mounted on the right side of the outer frame, an inner frame disposed inside the outer frame, a grinding table connected above the outer frame, and a main shaft movably connected between the outer frame and the grinding table on the inner side. A shaking mechanism is disposed on the left side of the main shaft for shaking and transmitting crushed dried fruits and vegetables to the left, and a connecting sleeve is mounted above the main shaft. A driven rod is disposed on the right side of the connecting sleeve, and a mounting plate is connected to the front side of the driven rod. A brush is disposed at the bottom of the mounting plate. A support plate is mounted on the rear side above the outer frame, and a microscopic detector is connected to the left side above the support plate. A threaded rod is movably connected to the left side above the outer frame for automatically transmitting the received crushed dried fruits and vegetables upward, so that the testing personnel can use the microscopic detector to test the crushed dried fruits and vegetables for aflatoxin.

[0005] Preferably, a toothed rack is installed on the outer ring above the grinding table, and a receiving groove is provided on the left side above the grinding table.

[0006] Preferably, a turntable is mounted on the outer side of the main shaft, and an arc-shaped protrusion is distributed on the outer ring above the turntable.

[0007] Preferably, the shaking mechanism includes a slide rod slidably connected to the inner side of the receiving groove, and a receiving plate is movably connected to the left side of the slide rod. A top rod is connected below the slide rod, and a ball bearing is slidably connected to the bottom of the top rod.

[0008] Preferably, the upper part of the turntable is configured to intermittently collide with the ball bearings via the protrusion and the top rod, and the left side of the receiving plate is movably connected to the inner side of the receiving groove via a rod.

[0009] Preferably, baffles are installed on both the left and right sides of the driven rod, and a feed hopper is provided between the baffles. A pressure roller is fixed on the outside of the driven rod, and a transmission gear is provided on the outside of the right end of the driven rod. The two transmission gears are inclined.

[0010] Preferably, a brush is connected to the bottom of the mounting plate, and the bottom of the brush is in contact with the top of the grinding table. The mounting plate is fixedly connected to the baffle by screws.

[0011] Preferably, a receiving platform is threadedly connected to the lower outer side of the threaded rod, and a smooth rod is connected through the inner side above the receiving platform. The receiving platform is located on the lower left side of the receiving groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This invention is equipped with pressure rollers, transmission gears, racks, and brushes. Utilizing the rotation of the main shaft, it effectively drives the driven rod, baffle, feed hopper, pressure rollers, transmission gears, mounting plate, brushes, and screws to revolve around the center of the main shaft simultaneously. When one transmission gear revolves, it rotates in conjunction with the rack, thus enabling the two pressure rollers to rotate inwards simultaneously in conjunction with the other transmission gear. This effectively performs initial crushing of the dried fruits and vegetables above the two pressure rollers. Furthermore, the rolling action of the pressure rollers against the surface of the grinding table effectively further crushes the initially crushed dried fruit and vegetable powder. Then, the revolving brush effectively sweeps the twice-crushed dried fruits and vegetables into the receiving plate inside the receiving trough. Compared with existing technologies, this invention can automatically crush and guide sampled dried fruits and vegetables, facilitating subsequent comprehensive aflatoxin testing of the dried fruits and vegetables, both inside and out.

[0014] 2. This invention is equipped with a shaking mechanism. Utilizing the rotation of the turntable, it also works in conjunction with the intermittent upward pressure of the ball bearings and the push rod by the arc-shaped protrusions. The intermittent upward movement of the push rod effectively shakes the receiving plate and the dried fruit and vegetable powder it holds. Compared to existing technologies, this effectively conveys the dried fruit and vegetable powder above the receiving plate to the receiving platform. The rotation of the threaded rod effectively and automatically transports the receiving platform and the dried fruit and vegetable powder it holds to the bottom of the microscopic detector, thus facilitating the inspection personnel's testing for aflatoxin in the dried fruit and vegetable powder above the receiving platform using the microscopic detector.

[0022] Please see Figure 1-5An embodiment of the present invention provides an intelligent food testing station, comprising an outer frame 1, a pusher 2, an inner frame 3, a grinding table 4, a rack 401, a receiving groove 402, a main shaft 5, a turntable 501, a protrusion 502, a shaking mechanism 6, a slide rod 601, a receiving plate 602, a top rod 603, a ball bearing 604, a connecting sleeve 7, a driven rod 8, a baffle 801, a feed hopper 801a, a pressure roller 802, a transmission gear 803, a mounting plate 9, a brush 10, a screw 11, a support plate 12, a microscopic detector 13, a threaded rod 14, a receiving platform 1401, and a smooth rod 1402. The pusher 2 is installed on the right side of the outer frame 1, and the inner frame 3 is provided inside the outer frame 1. The outer frame 1... The outer frame 1 is connected to a grinding table 4, and a main shaft 5 is movably connected to the inner side of the grinding table 4. A shaking mechanism 6 is provided on the left side of the main shaft 5, which can shake and transmit the broken dried fruits and vegetables to the left. A connecting sleeve 7 is installed above the main shaft 5. A driven rod 8 is provided on the right side of the connecting sleeve 7. A mounting plate 9 is connected to the front side of the driven rod 8. A brush 10 is provided at the bottom of the mounting plate 9. A support plate 12 is installed on the rear side of the upper part of the outer frame 1. A microscopic detector 13 is connected to the left side of the upper part of the support plate 12. A threaded rod 14 is movably connected to the left side of the upper part of the outer frame 1, which can automatically transmit the received broken dried fruits and vegetables upward, so that the inspectors can use the microscopic detector 13 to detect aflatoxin in the broken dried fruits and vegetables.

[0023] Example 1

[0024] Please see Figure 1-2 and Figure 4-5A rack 401 is installed on the outer ring above the grinding table 4, and a receiving groove 402 is opened on the left side above the grinding table 4. Baffles 801 are installed on both sides of the driven rod 8, and a feeding hopper 801a is set between the baffles 801. A pressure roller 802 is fixed on the outside of the driven rod 8, and a transmission gear 803 is set on the outside of the right end of the driven rod 8. The two transmission gears 803 are inclined. A brush 10 is connected to the bottom of the mounting plate 9, and the bottom of the brush 10 is in contact with the top of the grinding table 4. The mounting plate 9 is fixedly connected to the baffle 801 by screws 11. First, the dried fruits and vegetables to be sampled are placed between the two pressure rollers 802 through the feeding hopper 801a. Then, the servo motor at the bottom of the outer frame 1 is started to drive the main shaft 5 to rotate, and at the same time, the driven rod 8, baffle 801, feeding hopper 801a, pressure roller 802, transmission gear 803, mounting plate 9, brush 10 and screw 11 revolve around the center of the main shaft 5. One of the transmission gears 803 on the right side of the driven rod 8 meshes with the rack 401 on the grinding table 4. Therefore, when the transmission gear 803 revolves, it can rotate with the help of the rack 401. Since the two transmission gears 803 are meshed with each other, the two pressure rollers 802 can also rotate inward at the same time under the action of the two transmission gears 803 rotating inward simultaneously. This allows the dried fruits and vegetables above the two pressure rollers 802 to be initially crushed. At this time, the dried fruits and vegetables after initial crushing will fall onto the grinding table 4 and be crushed again by the pressure rollers 802 that are in contact with the upper part of the grinding table 4. Then, under the action of the brush 10 revolving, the dried fruits and vegetables after the two crushings are effectively swept into the inner side of the receiving plate 602 inside the receiving trough 402. The above structure can automatically crush and guide the sampled dried fruits and vegetables, which is convenient for subsequent all-round aflatoxin testing of the inside and outside of the dried fruits and vegetables.

[0025] Example 2

[0026] Please see Figure 1-3A turntable 501 is mounted on the outer side of the main shaft 5, and an arc-shaped protrusion 502 is distributed in an array on the outer ring above the turntable 501. The shaking mechanism 6 includes a slide rod 601 slidably connected to the inner side of the receiving groove 402, and a receiving plate 602 is movably connected to the left side of the slide rod 601. A push rod 603 is connected below the slide rod 601, and a ball bearing 604 is rolledly connected to the bottom of the push rod 603. The ball bearing 604 cooperates with the push rod 603 above the turntable 501 through the protrusion 502. 604 is an intermittent collision setting. The left side of the receiving plate 602 is movably connected to the inner side of the receiving groove 402 via a rod. The lower outer side of the threaded rod 14 is threadedly connected to the receiving platform 1401, and the inner side of the receiving platform 1401 is connected through the smooth rod 1402. The receiving platform 1401 is located on the lower left side of the receiving groove 402. When the spindle 5 rotates, it can also drive the turntable 501 to rotate. The outer ring of the turntable 501 has an arc-shaped protrusion 50 distributed on it. 2. The protrusion 502 abuts against the top rod 603 through the ball bearing 604. Therefore, when the turntable 501 rotates, the arc-shaped protrusion 502 can intermittently squeeze the ball bearing 604 and the top rod 603 upward. Through the intermittent upward movement of the top rod 603, the receiving plate 602 and the dried fruit and vegetable powder received above it can be shaken, so that the dried fruit and vegetable powder above the receiving plate 602 can be conveyed to the left and fall above the receiving platform 1401. Then, the servo motor in the upper left corner of the outer frame 1 is started by the control button to drive the threaded rod 14 to rotate. During the rotation of the threaded rod 14, the receiving platform 1401 and the dried fruit and vegetable powder received above it can be effectively conveyed upward automatically and placed just below the microscopic detector 13. Finally, the operator can use the microscopic detector 13 to detect aflatoxin in the dried fruit and vegetable powder above the receiving platform 1401.

[0027] Working principle: When using it, such as Figure 1-2 and Figure 4-5As shown, the dried fruits and vegetables to be sampled are first placed between the two pressure rollers 802 through the feed hopper 801a. Then, the servo motor at the bottom of the outer frame 1 drives the main shaft 5 to rotate, simultaneously causing the driven rod 8, baffle 801, feed hopper 801a, pressure rollers 802, transmission gear 803, mounting plate 9, brush 10, and screws 11 to revolve around the center of the main shaft 5. Since the bottom of one of the transmission gears 803 on the right side of the driven rod 8 meshes with the rack 401 on the grinding table 4, when the transmission gear 803 revolves, it can rotate under the cooperation of the rack 401. Due to the meshing of the two transmission gears 803, the rotation is complete. With the two transmission gears 803 rotating inwards simultaneously, the two pressure rollers 802 also rotate inwards simultaneously, thus initially crushing the dried fruits and vegetables above the two pressure rollers 802. At this time, the initially crushed dried fruits and vegetables will fall onto the grinding table 4 and be crushed again by the pressure rollers 802 that are in contact with the grinding table 4. Then, under the action of the brush 10 revolutions, the dried fruits and vegetables after the two crushings are effectively swept into the inner side of the receiving plate 602 inside the receiving trough 402. The above structure can automatically crush and guide the sampled dried fruits and vegetables, which facilitates the subsequent comprehensive detection of aflatoxin inside and outside the dried fruits and vegetables.

[0028] like Figure 1-3 As shown, when the main shaft 5 rotates, it also drives the turntable 501 to rotate. An arc-shaped protrusion 502 is distributed in an array on the outer ring above the turntable 501. The protrusion 502 contacts the push rod 603 via the ball bearings 604. Therefore, when the turntable 501 rotates, the arc-shaped protrusions 502 intermittently press the ball bearings 604 and the push rod 603 upwards. The intermittent upward movement of the push rod 603 effectively drives the receiving plate 602 and the dried fruit and vegetable powder it receives above to vibrate, thereby causing the area above the receiving plate 602 to shake. The dried fruit and vegetable powder can be conveyed to the left and fall above the receiving platform 1401. Then, the servo motor in the upper left corner of the outer frame 1 is activated by the control button to drive the threaded rod 14 to rotate. During the rotation of the threaded rod 14, the receiving platform 1401 and the dried fruit and vegetable powder received above it can be effectively conveyed upwards and placed just below the microscopic detector 13. Finally, the dried fruit and vegetable powder above the receiving platform 1401 can be tested for aflatoxin by the microscopic detector 13, thus completing a series of tasks.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
