[0045] At least two sorting robots 10 are placed on both sides of the ninth feeding conveyor belt 309. The sorting robots 10 separate and classify the kernels on the ninth feeding conveyor belt 309 according to the divided levels;

[0046] The classified kernels are conveyed to the vacuum packing machine 20 through the ninth feeding conveyor belt 309 for vacuum packing.

[0047] The automatic feeding raw material warehouse 1 grabs the macadamia nuts with green shells to be processed piled in the raw material warehouse and classifies them through the screening mechanism. The automatic feeding raw material warehouse 1 then releases the classified macadamia nuts and conveys them to the nut opening machine 2 through the first feeding conveyor belt 301 for opening. Subsequently, they are automatically processed through the kernel shell vibration screening machine 3, nut color sorting machine 4, nut cleaning machine 5, kernel temporary storage box 6, high-temperature continuous withering machine 7, continuous flavoring machine 8 and short-wave sterilizer 9.

The feeding intelligent visual inspection device 12 adopts the Keyence visual system VS-L. The multi-degree-of-freedom mechanical bucket 11 grabs the raw materials piled in the raw material warehouse through the pitching and swinging of the large arm 112 and the small arm 113, and collects image signals through the feeding intelligent visual inspection device 12, thereby transmitting visual inspection signals to the production line control system.

[0049] Preferably, the automatic feeding raw material bin 1 includes a raw material bin cylinder 13, in which a screening mechanism is installed. The screening mechanism divides the raw material bin cylinder 13 into an upper half bin and a lower half bin; the screening mechanism includes an upper sieve plate 131 and a lower sieve plate 132 which are provided with the same aperture and number of sieve holes, and the sieve holes of the upper sieve plate 131 and the lower sieve plate 132 correspond to each other one by one; the upper sieve plate 131 and the lower sieve plate 132 are coaxially arranged with the raw material bin cylinder 13 through a rotating shaft. The first driving mechanism 133 drives the upper sieve plate 131 to rotate around the rotating shaft, and the second driving mechanism 134 drives the lower sieve plate 132 to rotate around the rotating shaft. The first driving mechanism 133 drives the upper sieve plate 131 to cooperate with the second driving mechanism 134 to drive the lower sieve plate 132, so that the upper sieve plate 131 and the lower sieve plate 132 are staggered by an angle, and the upper sieve plate 131 and the lower sieve plate 132 can maintain a fixed staggered angle and rotate synchronously. By staggering the upper sieve plate 131 and the lower sieve plate 132 by different angles to adjust the size of the overlapping part of the sieve holes of the upper sieve plate 131 and the lower sieve plate 132, macadamia nuts of different sizes can be screened to achieve preliminary grading. Also, by keeping the upper sieve plate 131 and the lower sieve plate 132 rotating synchronously at a fixed staggered angle, the function of stirring the lowermost layer of macadamia nuts in the upper half bin is realized, so that the macadamia nuts can quickly pass through and enter the lower half bin, improving the screening efficiency and effect.

[0050] Specifically, a plurality of stirring protrusions are fixedly welded on the upper surface of the upper sieve plate 131. The plurality of stirring protrusions can be arranged radially or spirally at intervals to strengthen the stirring effect during the rotation of the upper sieve plate 131 and prevent raw materials from piling up.

[0051] Specifically, the rotating mounting seat 111 is fixedly installed at the top of the outer wall of the raw material bin cylinder 13.

The feeding intelligent vision detection device 12 is installed on the side of the rotating mounting seat 111 and faces the raw material pile in the raw material warehouse. The rotating mounting seat 111 drives the large arm 112 to rotate around the vertical direction and face the raw material pile. The large arm 112 swings downward so that the bucket 114 moves down to the raw material pile, and then the small arm 113 swings downward so that the bucket 114 grabs the raw materials. The large arm 112 swings upward to raise the bucket 114, and the rotating mounting seat 111 drives the large arm 112 to rotate so that the bucket 114 turns to the upper opening of the raw material bin cylinder 13. The large arm 112 and the small arm 113 cooperate to pour the grabbed raw materials into the upper half bin of the raw material bin cylinder 13.

[0052] Preferably, a ring of teeth is provided on the outer periphery of both the upper sieve plate 131 and the lower sieve plate 132. The first driving mechanism 133 includes a first driving motor and a first driving gear, and the second driving mechanism 134 includes a second driving motor and a second driving gear 1341. A transmission slit 135 is formed in the side wall of the raw material silo barrel 13, and the transmission slit 135 corresponds to the teeth of the upper sieve plate 131 and the lower sieve plate 132. The first driving motor and the second driving motor are installed on the outer wall of the raw material silo barrel 13. The first driving motor drives the first driving gear, and the first driving gear meshes with the teeth of the upper sieve plate 131 in the transmission slit 135. The second driving motor drives the second driving gear 1341, and the second driving gear 1341 meshes with the teeth of the lower sieve plate 132 in the transmission slit 135. The first driving motor drives the first driving gear to drive the upper sieve plate 131 to rotate, and the second driving motor drives the second driving gear 1341 to drive the lower sieve plate 132 to rotate. By controlling the first driving motor and the second driving motor, the upper sieve plate 131 and the lower sieve plate 132 are staggered at different angles, and then by controlling the first driving motor and the second driving motor, the upper sieve plate 131 and the lower sieve plate 132 are kept at the same rotational speed.

[0053] Specifically, the bottom end of the rotating shaft is fixed to the bottom of the raw material silo barrel 13. Bearing holes are provided in the centers of both the upper sieve plate 131 and the lower sieve plate 132 from the lower surface to rotatably connect with the top of the rotating shaft through bearings. The bearings are embedded in the upper sieve plate 131 and the lower sieve plate 132, so that the upper sieve plate 131 and the lower sieve plate 132 are in contact. The teeth of the upper sieve plate 131 and the lower sieve plate 132 are in the form of annular tooth rings. The outer peripheral edges of the upper sieve plate 131 and the lower sieve plate 132 are arranged in a stepped shape to overlap with the annular tooth rings and are fixedly connected by a set of screws. An annular groove is formed in the middle position of the inner wall of the raw material silo barrel 13. The annular tooth ring of the upper sieve plate 131 extends into the annular groove, and the upper surface of the annular tooth ring abuts against the upper wall of the annular groove. The annular tooth ring of the lower sieve plate 132 extends into the annular groove, and the upper surface of the annular tooth ring abuts against the lower wall of the annular groove. The transmission slit 135 communicates with the annular groove. The first driving gear and the second driving gear 1341 are coaxially arranged. The first driving gear extends into the transmission slit 135 to mesh with the annular tooth ring of the upper sieve plate 131, and the second driving gear 1341 extends into the transmission slit 135 to mesh with the annular tooth ring of the lower sieve plate 132.

[0054] Preferably, a piezoelectric sensing device is installed at the bottom of the raw material silo barrel 13. The piezoelectric sensing device is used to measure the weight of the macadamia nuts to be processed in the lower half of the silo and send signals to the production line control system to control the storage volume in the lower half of the silo. An infrared sensing device is installed in the upper half of the raw material silo barrel 13. The infrared sensing device is used to limit the height of the macadamia nuts to be processed in the upper half of the silo and send signals to the production line control system to control the storage volume in the upper half of the silo. The piezoelectric sensing device and the infrared sensing device work together to ensure that the raw materials stored in the raw material silo barrel 13 do not exceed the set storage volume.

[0055] Preferably, a raw material discharge port 136 is provided on the side wall of the lower half of the raw material silo 13, and the raw material discharge port 136 corresponds to the first feeding conveyor belt 301; a gate 137 for blocking the raw material discharge port 136 is installed on the outer wall of the raw material silo 13, and the third driving mechanism 138 drives the gate 137 to open and close. When the raw material in the lower half reaches the set storage volume, the third driving mechanism 138 drives the gate 137 to open, and the raw material falls through the raw material discharge port 136 to the lower part of the first feeding conveyor belt 301 for rear conveyance.

[0056] Specifically, the raw material discharge port 136 is located at the bottom of the side wall of the raw material silo 13, a guide pipe is set on the outer wall of the raw material silo 13, and a support frame is installed on the guide pipe; the third driving mechanism 138 adopts a cylinder, the cylinder body of the cylinder is installed on the support frame, and a vertical guide groove is opened on the support frame. The gate 137 is inserted into the guide groove, and the driving rod of the cylinder is hinged to the upper end of the gate 137.

[0057] Specifically, in the initial state, the angle of the upper sieve plate 131 and the lower sieve plate 132 is staggered to prevent the raw material from falling. When the infrared sensor detects that the raw material has reached the set limited height, the angle of the upper sieve plate 131 and the lower sieve plate 132 is changed to the raw material that can pass the minimum level. When the detection signal of the piezoelectric sensor does not change, that is, after all the raw materials of the minimum level are screened out, and when the detection signal of the piezoelectric sensor reaches the set value, the gate 137 is opened to release the raw material. When the detection signal of the piezoelectric sensor does not change, that is, after all the raw materials of the minimum level are screened out, the gate 137 is opened to release the raw material, and the preliminary classification of the raw material of the minimum level is completed. At this time, when the piezoelectric sensor senses zero pressure, the angle of the upper sieve plate 131 and the lower sieve plate 132 is changed to the raw material that can pass the next level, and the above steps are repeated to screen out all the raw materials of this level. The preliminary classification can be set to several levels according to the needs for classification, so that the upper half warehouse and the lower half warehouse are evenly divided into the raw material silo 13, so that the raw materials in the upper half warehouse can be screened out all at once, reducing the classification action, thereby improving efficiency.

[0059] Specifically, the nut opening machine 2 uses the macadamia nut opening machine of Yunnan Aofu Intelligent Equipment Co., Ltd. The nut opening machine 2 adopts a fully automatic saw blade for cutting, with a processing diameter range of 12 - 38 mm. The sawing angle and depth can be numerically controlled and adjusted, effectively solving problems such as difficult nut sawing and high labor costs.

[0060] Specifically, the kernel - shell vibration screening machine 3 uses the nut shelling machine of Yunnan Aofu Intelligent Equipment Co., Ltd. Due to the different sizes of the nut shells and kernels, through the vibration of the sieve plate, the separation of the kernels and nut shells is achieved. The nut shelling machine is dedicated to the screening treatment of nut shells and kernels, effectively solving the problems of difficult manual selection and low efficiency.

[0061] Specifically, the nut color - sorter 4 uses the high - performance macadamia nut color - sorter of Shandong Kelida. The macadamia nuts enter the color - sorter from the third feeding conveyor belt 303 and enter the sorting box through the inclined chute. After entering the sorting box, the nuts pass through between the image sensor CCD and the background device. Under the action of the light source signal, CCD receives the composite light signal from the nuts, enabling the system to generate an output signal, which is amplified and then transmitted to the operation processing system. Then, the control system issues an instruction to drive the jet solenoid valve to act, blowing away the inferior nuts such as those with mildew or insect bites.

[0062] Specifically, the nut cleaner 5 uses the green macadamia nut cleaner. The water flow of the green macadamia nut cleaner is precisely controlled, energy - efficient, and can effectively remove dust, debris, etc. on the surface of the kernels, reducing the labor cost of manual cleaning.

[0064] Specifically, the high - temperature continuous blanching machine 7 uses a Chinese patent named a macadamia nut constant - temperature circulating blanching device. The high - temperature continuous blanching machine 7 is first pre - heated to a certain temperature to ensure that the kernels can quickly reach the baking temperature after entering; the kernels are continuously fed into the high - temperature continuous blanching machine 7 by the sixth feeding conveyor belt 306; the high temperature can quickly destroy the enzyme activity in the nuts, reduce the generation of astringent taste, and at the same time promote the rapid evaporation of the internal moisture of the nuts. The high - temperature continuous blanching machine 7 removes the astringent taste in the kernels through short - time high - temperature baking to achieve a good taste, and at the same time sterilizes and disinfects to facilitate subsequent processing and better flavoring. The high - temperature continuous blanching machine 7 has the characteristics of reasonable air - flow distribution, precise temperature control, and energy - efficiency. Both the production temperature and speed can be adjusted, with a temperature of 120 - 160 °C, a processing time of 10 - 15 minutes, and a material thickness of about 50 mm.

[0065] Specifically, the continuous flavoring machine 8 uses a drum-type flavoring machine of Yunnan Aofu Intelligent Equipment Co., Ltd. The continuous flavoring machine 8 enables the nuts and spices to be fully integrated through continuous stirring, maximizing the flavor of the nuts while making it more convenient and efficient.

[0066] Specifically, the short-wave sterilization machine 9 uses an ultraviolet sterilization furnace. The ultraviolet lamps are evenly distributed inside the equipment. When the nuts are conveyed to below the ultraviolet lamps by the eighth feeding conveyor belt 308, the irradiation of microorganisms such as bacteria and viruses is carried out for sterilization.

[0067] Specifically, the sorting robot 10 uses a Dobot CR16 robot. The sorting robot 10 classifies the nuts that have been preliminarily graded in the previous process according to their shapes and sizes. The nuts sorted by the sorting robot 10 are placed on the ninth feeding conveyor belt 309 according to the classified levels, and are specifically arranged along the vertical conveying direction.

The grading intelligent vision detection device 40 collects images of the nuts conveyed in front of the sorting robot 10, and the graded data after collection and processing is transmitted to the production line control system in real time.
