Description

Technical Field

[0001] The present invention relates to the technical field of nut transportation, and in particular to a quantitative conveying device and a quantitative conveying method for nut processing. Background Art

[0002] Nuts usually refer to fruits with hard shells and edible kernels. Common nuts include walnuts, almonds, cashews, hazelnuts, macadamia nuts, pistachios, etc. Nuts are rich in nutrients such as protein, fat (mainly unsaturated fatty acids), vitamins and minerals, and are one of the important sources of nutrition in people's daily diet.

[0003] Chinese patent CN217971327U discloses a conveying mechanism for a nut drying line, which belongs to the technical field of nut conveying mechanisms. The device drives a collecting box and a beating roller to swing up and down by starting a motor. The beating roller continuously strikes the conveyor belt upwards to knock down the broken materials and shells blocked inside the holes of the conveyor belt, thereby preventing the holes of the conveyor belt from being blocked and making it impossible to screen out the broken materials and shells. However, during the transportation process, the nuts dropped on the conveyor belt are unevenly distributed, and the nuts will be lost during the transportation process, that is, the broken nuts form nut crumbs, while the nut crumbs located above the nuts cannot be completely screened out. At the same time, during the subsequent drying, in a large nut pile, the nuts inside are not dried thoroughly, which is not convenient for the subsequent storage and transportation of the nuts.

[0015] The present invention also discloses a quantitative conveying method for nut processing, which uses the above-mentioned quantitative conveying device.

[0016] Compared with the prior art, the present invention provides a quantitative conveying device and a quantitative conveying method for nut processing, which have the following beneficial effects:

[0017] 1. The quantitative conveying device is provided with an auxiliary fan and an auxiliary electric heating wire in the annular shell, so that the heat flow passes through the quantitative bin, thereby heating and drying the nuts inside. At the same time, the hot air flow can blow the debris that is tightly adhered to the nuts into the hollow cylinder, and is eventually attracted and collected by the negative pressure device. The staff can recycle the collected nut debris, thereby reducing the drying cost of the nuts and increasing the practicality of the device. At the same time, by arranging filter columns in the quantitative bin, the nuts can be screened by utilizing the gaps between the filter columns, which facilitates the processing of nut debris and improves the quality of the nuts.

[0018] 2. The quantitative conveying device is provided with a telescopic isolation cover inside the quantitative bin. The rotating adjusting bolt drives the telescopic isolation cover to move left and right in the quantitative bin, thereby adjusting the size of the storage space in the quantitative bin so that the size can be adjusted according to the type of nuts being transported. In this way, different types of nuts can be quantitatively transported separately, which is convenient for the staff to handle them and increases the scope of application of the device.

[0019] 3. The quantitative conveying device is provided with an arc-shaped rack meshing with the cleaning gear inside the annular sealing plate. When the quantitative bin rotates to the arc-shaped rack, the cleaning gear will mesh with the arc-shaped rack and rotate, and then the cleaning gear drives the transmission gear to rotate, so that the transmission gear drives the filter column at one end to start rotating. The rotation of the filter column will loosen the nuts stuck between the filter columns and fall off or be crushed and cracked. At the same time, the scraper at the bottom of the filter column will clean and scrape the surface of the filter column, so that the nut fragments stuck on the filter column fall off, thereby preventing small nuts from getting stuck between multiple groups of filter bags and causing blockage. At the same time, the scraper can clean the nut fragments stuck on the filter column and further clean the nut fragments.

[0020] 4. The quantitative conveying device is provided with a quantitative brush inside the feed port, which cleans off the excess nuts on the top of the quantitative bin. Since the bottom of the quantitative brush just slides over the top of the quantitative bin, the quantitative brush cleans off the excess nuts on the rotating quantitative bin, preventing the nuts on the top of the quantitative bin from being squeezed between the top of the quantitative bin and the top of the inner wall of the annular shell, causing the nuts to be broken and damaged, thereby ensuring the integrity of the nuts.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1-9 , a quantitative conveying device, comprising an equipment housing 2, a feed port 6 and a discharge port 7 arranged on the equipment housing 2, and a conveyor 1 installed at the bottom of the discharge port 7 of the equipment housing 2, the equipment housing 2 is equipped with a heating component 22 for drying nuts, the equipment housing 2 is internally equipped with a rotatable runner 3, a plurality of groups of quantitative devices 5 are installed around the runner 3, the quantitative devices 5 are used to accommodate nuts and screen nuts, the runner 3 is used to transport nuts, forcing the nuts to pass through the feed port 6, the heating component 22 and the discharge port 7 in sequence, a negative pressure device 4 is fixedly installed on one side of the equipment housing 2, the negative pressure device 4 is used to collect nut debris screened out of the runner 3;

[0033] When the nuts enter the equipment housing 2 through the feed port 6, the runner 3 rotates and drives the quantitative device 5 to move. When the quantitative device 5 passes the feed port 6, the quantitative device 5 receives the nuts and screens them. At the same time, the negative pressure device 4 operates to collect the screened nut debris. When the quantitative device 5 passes the heating component 22, the heating component 22 operates and dries the nuts. When the quantitative device 5 passes the discharge port 7, the nuts are discharged from the discharge port 7 onto the conveyor 1.

[0034] The equipment housing 2 includes an annular shell 21, and the feed port 6 and the discharge port 7 are both provided on the annular shell 21. A feed pipe 28 is also fixed to the feed port 6. The runner 3 includes an outer rotating plate 31 provided inside the annular shell 21, and a ring 32 is fixed to one side of the outer rotating plate 31. A servo motor 11 is fixed to one side of the annular shell 21, and the output shaft of the servo motor 11 is fixed to the outer rotating plate 31.

[0035] An annular inner cavity 24 is provided inside the annular housing 21. An air outlet 27 is provided on the inner wall of the annular inner cavity 24. An air inlet 29 is provided on the outer wall of the annular inner cavity 24. The heating assembly 22 includes an auxiliary fan 25 and an auxiliary heating wire 26 fixed to the inner wall of the annular housing 21. The auxiliary fan 25, the auxiliary heating wire 26, the air inlet 29, and the air outlet 27 are positioned correspondingly. The auxiliary heating wire 26 is located on the air outlet side of the auxiliary fan 25.

[0036] The quantitative device 5 includes a quantitative bin 51 fixedly embedded in the surface of the ring 32. The quantitative bin 51 is used to receive nuts to be processed. A plurality of evenly distributed filter columns 52 are installed inside the quantitative bin 51. The filter columns 52 are used to filter debris from the nuts to be processed. A hollow cylinder 33 is provided on the inner side of the ring 32. The hollow cylinder 33 is fixed to and communicates with the bottom end of each quantitative bin 51.

[0037] Specifically, after the nuts are spread all over the quantitative bin 51, the multiple evenly distributed filter columns 52 at the bottom of the quantitative bin 51 will first screen the nuts, so that the debris and impurities in the nuts pass through the gaps between the multiple groups of filter columns 52 and enter the hollow cylinder 33. When the servo motor 11 is running, it drives the outer rotating plate 31 and the ring 32 to rotate, and the quantitative bin 51 moves with the ring 32 to the auxiliary heating wire 26. At this time, the auxiliary heating wire 26 heats the air inside the annular shell 21, and the auxiliary fan 25 blows the hot air to the top of the quantitative bin 51, passes through the interior of the quantitative bin 51, and comes out from the bottom thereof into the hollow cylinder 33. In this process, the nuts will be heated and dried, thereby reducing the residual moisture in the nuts, thereby increasing the storage time of the nuts, and at the same time, the debris that sticks tightly to the nuts will be blown into the hollow cylinder 33. At the same time, the nut debris inside the hollow cylinder 33 is sucked and collected by the negative pressure device 4.

[0038] By arranging an auxiliary fan 25 and an auxiliary heating wire 26 in the annular shell 21, a hot air flow passes through the quantitative bin 51, thereby heating and drying the nuts inside. At the same time, the hot air flow can blow the debris that sticks tightly to the nuts into the hollow cylinder 33, and finally be attracted and collected by the negative pressure device 4. The staff can recycle the collected nut debris, thereby reducing the drying cost of the nuts and increasing the practicality of the device. At the same time, by arranging a filter column 52 in the quantitative bin 51, the nuts can be screened by utilizing the gaps between the filter columns 52, which facilitates the processing of nut debris and improves the quality of the nuts.

[0039] Example 2: See Figure 1-9 , which is different from the above embodiment, the filter column 52 is rotatably connected to the inner wall of the quantitative chamber 51, one end of the filter column 52 extends to the outside of the quantitative chamber 51 and is fixed with a transmission gear 57, the transmission gears 57 on adjacent filter columns 52 are meshed with each other, the corner of the quantitative chamber 51 is rotatably connected to a cleaning gear 58 that meshes with the transmission gear 57, and a scraper 56 is fixed at the bottom of multiple filter columns 52;

[0040] The quantitative chamber 51 is provided with a quantitative baffle 53 inside, and a telescopic isolation cover 54 is fixedly connected between the top edge of the quantitative baffle 53 and the inner wall of the quantitative chamber 51. The side wall of the quantitative chamber 51 is threadedly connected to an adjusting bolt 55. One end of the adjusting bolt 55 extends into the quantitative chamber 51 and is rotatably connected to the quantitative baffle 53. The other end of the adjusting bolt 55 passes through the outside of the outer rotating plate 31. The adjusting bolt 55 is used to push the quantitative baffle 53 to reciprocate inside the quantitative chamber 51, and the quantitative baffle 53 drives the telescopic isolation cover 54 to expand inside the quantitative chamber 51, thereby adjusting the storage space in the quantitative chamber 51.

[0041] Specifically, before the nuts are transported, the staff adjusts the number of nuts stored in the quantitative bin 51 according to the types of nuts to be transported and the subsequent work processes, i.e., drying, packaging or storage, etc. At this time, the adjusting bolt 55 is controlled to rotate inward or outward on the outer rotating plate 31, so that the adjusting bolt 55 pushes the quantitative baffle 53 at one end thereof to move left and right in the quantitative bin 51, thereby driving the telescopic isolation cover 54 connected to the top side of the quantitative baffle 53 to unfold on the top of the quantitative bin 51, thereby adjusting the storage space in the quantitative bin 51, and then the nuts enter from the feed pipe 28 and fall into the quantitative bin 51. At this time, the nuts are located in the area between the inside of the quantitative bin 51 and the outside of the quantitative baffle 53, so that the nuts are transported in a quantitative manner, which is convenient for the staff to handle them, and increases the applicability and practicality of the device. The nuts that fall into the quantitative bin 51 will have some nut fragments, and these nut fragments will pass through the filter column 52 at the bottom of the quantitative bin 51 and fall inside. Then the negative pressure device 4 generates negative pressure suction, so that the nut fragments inside are attracted and collected by the negative pressure device 4. It is particularly noted that the material of the telescopic isolation cover 54 is set to rubber, which has flexibility and plasticity so as to maintain a good shape when folded.

[0042] Example 3: See Figures 1-9 , different from the above embodiment, the negative pressure device 4 includes a fan 41, a filter bag 42 is fixed to the exhaust end of the fan 41, a negative pressure pipe 43 is fixed to the air inlet end of the fan 41, and an annular cover 44 is fixed to one end of the negative pressure pipe 43, the annular cover 44 is rotatably connected to the end of the hollow cylinder 33, an annular sealing plate 46 is fixedly sleeved on the outer side of the annular cover 44, the outer edge of the annular sealing plate 46 is fixed to the annular shell 21, and a negative pressure baffle 45 is fixed to the bottom edge of the annular cover 44, the negative pressure baffle 45 extends into the hollow cylinder 33, and the negative pressure baffle 45 intercepts nut fragments falling from the quantitative bin 51, so that they are sucked and cleaned by the negative pressure device 4;

[0043] An arc-shaped rack 47 is fixed to one side of the annular sealing plate 46 close to the outer rotating plate 31 , and a portion of the cleaning gear 58 located inside the arc-shaped rack 47 is meshed with the arc-shaped rack 47 .

[0044] Specifically, when nuts enter the quantitative bin 51, the intact nuts will stay inside the quantitative bin 51, and the nut crumbs and impurities will pass through the multiple groups of filter columns 52 and fall into the hollow cylinder 33 under the action of gravity. At this time, the fan 41 is started to generate negative pressure suction, and the negative pressure is transmitted to the annular cover 44 through the filter bag 42 and the negative pressure pipe 43, thereby forming a negative pressure inside the hollow cylinder 33. The negative pressure will attract the nut crumbs that fall into the hollow cylinder 33 and on the negative pressure baffle 45. The nut crumbs pass through the annular cover 44 in turn and enter the negative pressure pipe 43, and finally enter the filter bag 42 to be collected. The collected nut crumbs can then be recycled by the staff;

[0045] When the quantitative bin 51 leaves the bottom of the negative pressure baffle 45, negative pressure is formed inside the hollow cylinder 33 and is connected to the bottom of the quantitative bin 51 again. However, at this time, some nuts whose sizes are similar to the distance between the multiple groups of filter columns 52 will be stuck between the multiple groups of filter columns 52, unable to fall down, and unable to pass through the filter columns 52 to be sucked and cleaned by the negative pressure inside. Until the quantitative bin 51 moves to the arc-shaped rack 47, the cleaning gear 58 on the outside of the quantitative bin 51 will start to mesh with the arc-shaped rack 47 on the inside of the annular sealing plate 46, and then the arc-shaped rack 47 makes it move with it. The meshed cleaning gear 58 starts to rotate, and then the cleaning gear 58 drives the transmission gear 57 to rotate, so that the transmission gear 57 drives the filter column 52 at one end thereof to start rotating. The rotating filter column 52 will loosen the nuts stuck between the filter columns 52 and fall off or be crushed and cracked. At the same time, some nut fragments will stick to the surface of the filter column 52. At this time, the scraper 56 at the bottom of the filter column 52 will clean and scrape the surface of the filter column 52, so that the nut fragments stuck to the filter column 52 will fall off and be attracted by the negative pressure formed inside the hollow cylinder 33, and finally enter the negative pressure device 4.

[0046] Example 4: See Figures 1-9 , which is different from the above embodiment, a quantitative brush 23 is fixed to the inner wall of the feed port 6, and the quantitative brush 23 extends toward the ring 32, and the bottom of the quantitative brush 23 just slides over the top of the quantitative bin 51;

[0047] Specifically, when feeding, the nuts enter the quantitative bin 51 along the feed port 6 until the nuts are piled up on the quantitative bin 51. At this time, the servo motor 11 drives the outer rotating plate 31, the ring 32 and the quantitative bin 51 inside it to rotate in turn, and the bottom of the quantitative brush 23 just slides over the top of the quantitative bin 51. At this time, the quantitative bin 51 continues to rotate, and the bottom of the quantitative brush 23 will sweep the excess nuts on the quantitative bin 51 along its top, thereby preventing the nuts from being crushed by the rotating quantitative bin 51, thereby ensuring the integrity of the nuts.

[0048] Example 5: See Figure 1 - Figure 9This embodiment discloses a quantitative conveying method for nut processing, which uses the quantitative conveying device in the above embodiment.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
