Description

Technical Field

[0001] This invention relates to the field of nut processing technology, and in particular to a macadamia nut cleaning device with a debris collection function. Background Technology

[0002] Macadamia nuts are evergreen fruit trees belonging to the genus Macadamia in the family Proteaceae. They originated in the subtropical rainforests of southeastern Queensland and northeastern New South Wales in Australia. Also known as macadamia nuts or Australian walnuts, they are a precious edible nut with high oil content, rich nutrition, and unique flavor. They are known as the "Queen of Nuts" and the "King of Nuts" and have high economic value.

[0003] Currently, macadamia nuts need to be cleaned during processing to remove impurities adhering to their surface, thereby ensuring processing quality. In existing technologies, the cleaning of macadamia nuts is mostly done by placing them on several cleaning rollers, which are driven by a drive mechanism to rotate. As the rollers rotate, a water supply mechanism supplies water to the nuts, thus achieving the cleaning of macadamia nuts. However, after the macadamia nuts are cleaned, they may get stuck between the rollers, making it difficult to remove them and thus affecting the cleaning efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a macadamia nut cleaning device with a debris collection function to solve the technical problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides a macadamia nut cleaning device with a debris collection function, comprising a support plate, a variable diameter cleaning roller, a drive assembly, an adjustment assembly, and a water supply assembly. The support plate is provided in two sets, and the two sets of support plates are distributed opposite to each other. The variable diameter cleaning rollers are provided in several groups, and these rollers are rotatably arranged between two groups of support plates and distributed in a linear structure. The water supply assembly is positioned above the two sets of support plates and is used to supply water to the upper part of the variable diameter cleaning rollers. The drive assembly is mounted on the side wall of the support plate and is used to drive several variable diameter cleaning rollers to rotate synchronously, so as to provide frictional force to the surface of the nuts. The adjustment component is installed on the side wall of the support plate and is used to adjust the diameter of the plurality of variable diameter cleaning rollers, so that the diameter of the plurality of variable diameter cleaning rollers varies between a first diameter value and a second diameter value, wherein the first diameter value is greater than the second diameter value.

[0006] As a further improvement of the present invention: several of the variable diameter cleaning rollers have the same structure, each including a core roller and an annular air bladder. The end of the core roller is rotatably connected to the inner wall of the support plate, the annular airbag is disposed around the outside of the core roller, and a first pulley is fixedly disposed on the outer wall of the core roller corresponding to several variable diameter cleaning rollers. The drive assembly includes a motor, a rotating shaft, and a second transmission belt. The motor is fixedly mounted on the side wall of the bracket plate. One end of the rotating shaft is connected to the output end of the motor, and the other end is connected to one of the core rollers. The second transmission belt is sleeved on the outside of several first pulleys. The second transmission belt is a synchronous belt, and the first pulleys are synchronous pulleys adapted to the second transmission belt.

[0007] As a further improvement of the present invention: the core roller is hollow inside, and an air hole communicating with the inner cavity of the core roller is opened on the roller body located inside the annular air bladder; a gear is also fixedly installed on the outside of the rotating shaft. The adjusting assembly includes a piston rod, an extension rod, a push block, a slide rod, a second elastic element, a piston plate, and a rack. Each set of core rollers has a set of piston plates movably disposed within its inner cavity. Each set of piston plates has a set of piston rods fixedly disposed on one side. Several piston rods, with their ends away from the corresponding piston plates, pass through the core rollers and the support plate and extend to the outside of the support plate. Each set of piston rods has a set of extension rods fixedly disposed on its side wall. The sliding rod is slidably disposed on the side wall of the support plate. The rack is fixedly mounted on the upper part of the slide rod and can mesh with the gear. One end of the second elastic element is connected to the bracket plate and the other end is connected to the slide rod. Several sets of push blocks are provided in one-to-one correspondence with the extension rods. Several sets of push blocks are correspondingly arranged on the sides of several extension rods. Each set of push blocks has an inclined surface on its side wall.

[0008] As a further improvement of the present invention: the adjustment assembly further includes a first elastic element, a slider, and a guide rod. The guide rod is fixedly mounted on the side wall of the support plate. One end of the slider is fixedly connected to the piston rod, and the other end is slidably sleeved on the outside of the guide rod. One end of the first elastic element is connected to the support plate, and the other end is connected to the slider, which is used to provide elastic tension to the slider.

[0009] As a further improvement of the present invention: the outer wall of the annular airbag is provided with a number of evenly distributed protrusions.

[0010] As a further improvement of the present invention: a conveying component is also provided between the two sets of support plates, located below the several variable diameter cleaning rollers. The conveying component is used to convey the debris falling between the two adjacent sets of variable diameter cleaning rollers and the cleaned nuts in separate sections.

[0011] As a further improvement of the present invention: a second pulley is also fixedly provided on the outside of the rotating shaft. The conveying assembly includes two sets of shafts and an annular mesh belt sleeved on the two sets of shafts. The ends of the two sets of shafts are rotatably connected to the inner wall of the support plate, and a third pulley is fixedly installed on the outside of one set of shafts. The second pulley and the third pulley are connected by a first transmission belt.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects: In this embodiment of the invention, initially, the diameter of the variable-diameter cleaning rollers is a first diameter value. At this time, the distance between two adjacent sets of variable-diameter cleaning rollers is less than the diameter of the macadamia nut. When batch cleaning of macadamia nuts is required, the macadamia nuts to be cleaned can be placed on top of the variable-diameter cleaning rollers. Since the distance between two adjacent sets of variable-diameter cleaning rollers is less than the diameter of the macadamia nut, the nuts can act between the adjacent sets of variable-diameter cleaning rollers and cannot fall off between them. Subsequently, water is supplied to the top of the variable-diameter cleaning rollers through a water supply component. At the same time, a drive component drives the variable-diameter cleaning rollers to rotate synchronously. When the variable-diameter cleaning rollers rotate synchronously, they apply friction to the nuts, causing the nuts to rotate between the adjacent sets of variable-diameter cleaning rollers. Simultaneously, the variable-diameter cleaning rollers remove impurities from the surface of the nuts. The system, combined with the rinsing action of water, automatically cleans the nuts. After impurities are removed from the nut surface, they flow down between adjacent sets of variable-diameter cleaning rollers with the water, completely separating the impurities from the nuts. Once the nuts are cleaned, the diameter of several variable-diameter cleaning rollers is adjusted using an adjusting component, reducing their diameter to a second value. At this point, the distance between adjacent sets of variable-diameter cleaning rollers increases to a value greater than the diameter of the nut. The cleaned nuts then fall between these rollers, achieving automatic nut discharge. Compared to existing technologies, this system enables automatic cleaning and discharge of macadamia nuts. Furthermore, the cleaning process allows for the application of abrasive techniques to the nuts, ensuring that impurities are smoothly removed from the nut surface. It boasts advantages such as excellent cleaning effect and high cleaning efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0018] The present invention will be further explained below with reference to specific embodiments.

[0019] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a macadamia nut cleaning device with a debris collection function, including a support plate 10, variable diameter cleaning rollers 20, a drive assembly 30, an adjustment assembly 40, and a water supply assembly (not shown in the figure). Two sets of support plates 10 are provided, arranged opposite to each other. Several sets of variable diameter cleaning rollers 20 are provided, rotatably arranged between the two sets of support plates 10 and arranged in a linear sequence. The water supply assembly is located above the two sets of support plates 10 and is used to supply water to the upper part of the variable diameter cleaning rollers 20. The drive assembly 30 is installed on the side wall of the support plate 10 and is used to drive the variable diameter cleaning rollers 20 to rotate synchronously, providing friction to the surface of the nuts, causing debris to detach from the nut surface. The adjustment assembly 40 is installed on the side wall of the support plate 10 and is used to adjust the diameter of the variable diameter cleaning rollers 20, causing the diameter of the variable diameter cleaning rollers 20 to vary between a first diameter value and a second diameter value, where the first diameter value is greater than the second diameter value.

[0020] Initially, the diameter of the variable diameter cleaning rollers 20 is the first diameter value. At this time, the distance between two adjacent sets of variable diameter cleaning rollers 20 is smaller than the diameter of the macadamia nut. When batch cleaning of macadamia nuts is required, the macadamia nuts to be cleaned can be placed on top of the variable diameter cleaning rollers 20. Since the distance between two adjacent sets of variable diameter cleaning rollers 20 is smaller than the diameter of the macadamia nut, the nuts can act between the adjacent sets of variable diameter cleaning rollers 20 and cannot fall off between them. Then, water is supplied to the top of the variable diameter cleaning rollers 20 through the water supply component, and at the same time, the drive component 30 drives the variable diameter cleaning rollers 20 to rotate synchronously. When the variable diameter cleaning rollers 20 rotate synchronously, they apply friction to the nuts. Force causes the nuts to rotate between two adjacent sets of variable diameter cleaning rollers 20. At the same time, the variable diameter cleaning rollers 20 remove impurities from the surface of the nuts. Combined with the rinsing effect of water, the nuts are automatically cleaned. After the impurities are removed from the surface of the nuts, they can flow down between the two sets of variable diameter cleaning rollers 20 with the water, so that the impurities are completely separated from the nuts. After the nuts are cleaned, the diameter of some of the variable diameter cleaning rollers 20 is adjusted by the adjusting component 40, so that the diameter of some of the variable diameter cleaning rollers 20 is reduced to a second diameter value. At this time, the distance between the two sets of variable diameter cleaning rollers 20 increases to be greater than the diameter of the nuts. The cleaned nuts can fall between the two sets of variable diameter cleaning rollers 20, thereby realizing the automatic discharge of nuts.

[0021] Please see Figure 5 , Figure 6 as well as Figure 7 In one embodiment, several variable diameter cleaning rollers 20 have the same structure, each including a core roller 201 and an annular airbag 202. The end of the core roller 201 is rotatably connected to the inner wall of the support plate 10, and the annular airbag 202 is arranged around the outside of the core roller 201. A first pulley 205 is fixedly provided on the outer wall of the core roller 201 corresponding to several variable diameter cleaning rollers 20. The drive assembly 30 includes a motor 301, a rotating shaft 302, and a second transmission belt 306. The motor 301 is fixedly installed on the side wall of the support plate 10. One end of the rotating shaft 302 is connected to the output end of the motor 301, and the other end is connected to one of the core rollers 201. The second transmission belt 306 is sleeved on the outside of several first pulleys 205. The second transmission belt 306 is a synchronous belt, and the first pulleys 205 are synchronous pulleys adapted to the second transmission belt 306.

[0022] By placing macadamia nuts on top of several annular airbags 202 corresponding to several variable-diameter cleaning rollers 20, the macadamia nuts roll between two adjacent sets of annular airbags 202 under the action of gravity. The motor 301 drives the rotating shaft 302 to rotate forward, and the rotating shaft 302 drives one set of core rollers 201 to rotate forward. When the core roller 201 rotates forward, it drives the first pulley 205 outside it to rotate forward. When the first pulley 205 rotates forward, it drives the other core rollers 201 to rotate forward synchronously through the transmission action of the second transmission belt 306 and the other several first pulleys 205. When the core rollers 201 rotate forward synchronously, they can drive the several annular airbags 202 to rotate forward synchronously. When the several annular airbags 202 rotate forward synchronously, they drive the nuts to rotate. At this time, the annular airbags 202 can apply friction to the nuts, thereby removing the impurities on the surface of the nuts. With the water supply component, the automatic cleaning of the nuts is completed.

[0023] Please see Figure 4 , Figure 5 , Figure 6 as well as Figure 7 In one embodiment, the core roller 201 is hollow inside. An air hole 203 communicating with the inner cavity of the core roller 201 is provided on the roller body located inside the annular air bladder 202. A gear 303 is also fixedly installed on the outside of the rotating shaft 302. The adjusting assembly 40 includes a piston rod 404, an extension rod 405, a push block 407, a slide rod 408, a second elastic element 409, a piston plate 410, and a rack 411. A set of piston plates 410 is movably arranged in the inner cavity of each set of core rollers 201. A set of piston rods 404 is fixedly installed on one side of each set of piston plates 410. The ends of several piston rods 404 away from the corresponding piston plates 410 pass through... The piston rod 404 extends through the core roller 201 and the support plate 10 and extends to the outside of the support plate 10. Each set of piston rods 404 has a set of extension rods 405 fixedly installed on its side wall. The slide rod 408 is slidably installed on the side wall of the support plate 10. The rack 411 is fixedly installed on the upper part of the slide rod 408 and can mesh with the gear 303. One end of the second elastic member 409 is connected to the support plate 10 and the other end is connected to the slide rod 408. Several sets of push blocks 407 are provided in a one-to-one correspondence with the extension rods 405. Several sets of push blocks 407 are correspondingly installed on the sides of several sets of extension rods 405. Each set of push blocks 407 has an inclined surface 406 on its side wall.

[0024] When the motor 301 drives the rotating shaft 302 to rotate in the forward direction, thereby driving several core rollers 201 and several annular airbags 202 to rotate synchronously in the forward direction, the rotating shaft 302 can also drive the gear 303 to rotate synchronously in the forward direction. When the gear 303 rotates in the forward direction, several teeth of its gear 303 act sequentially on one end of the rack 411 to limit the second elastic element 409 to a compressed state. At this time, the several push blocks 407 and several extension rods 405 are separated, and the piston plate 410 is held at a certain position in the inner cavity of the core roller 201. The ring-shaped airbag 202 remains stationary, maintaining its diameter at the first value. After the nuts are cleaned, the motor 301 drives the shaft 302 to rotate in the opposite direction, which in turn drives the gear 303 to rotate in the opposite direction. When the gear 303 rotates in the opposite direction, the second elastic element 409 pushes the slide rod 408, causing the slide rod 408 to slide along the side wall of the support plate 10. The slide rod 408 drives the rack 411 and several push blocks 407 to move. When the rack 411 moves, the gear 303, rotating in the opposite direction, meshes with the rack 411, and... The sliding rod 408 continues to slide, which in turn drives several push blocks 407 to move. As the push blocks 407 move, their inclined surfaces 406 act on several extension rods 405, thereby pushing the extension rods 405 so that the piston rods 404 drive several piston plates 410 to move along the inside of several core rollers 201. This draws air from inside several annular airbags 202 into the inner cavity of several core rollers 201 through air holes 203, causing the annular airbags 202 to contract and their diameter to decrease. When several teeth of the gear 303 act on the other end of the rack 411, the gear 303 disengages from the rack 411, the second elastic element 409 is in a stretched state, the sliding rod 408 and the push blocks 407 no longer move, and the piston plates 410 remain stationary inside the core rollers 201. At this time, the diameter of the annular airbags 202 is at the second diameter value, and the cleaned nuts located between two adjacent sets of annular airbags 202 fall off by themselves, thus realizing the automatic discharge of nuts.

[0025] Please see Figure 4 In one embodiment, the adjustment assembly 40 further includes a first elastic element 401, a slider 402, and a guide rod 403. The guide rod 403 is fixedly disposed on the side wall of the support plate 10. One end of the slider 402 is fixedly connected to the piston rod 404, and the other end is slidably sleeved on the outside of the guide rod 403. One end of the first elastic element 401 is connected to the support plate 10, and the other end is connected to the slider 402, for providing elastic tension to the slider 402.

[0026] When the motor 301 drives the rotating shaft 302 to rotate in the reverse direction, thereby moving the push block 407, the inclined plane 406 acts on the extension rod 405, thereby moving the piston rod 404 and the piston plate 410. The piston rod 404 drives the slider 402 to slide along the outside of the guide rod 403, and the first elastic element 401 is stretched by force. After the nuts are discharged, the motor 301 drives the rotating shaft 302 and the gear 303 to rotate in the forward direction. When the gear 303 rotates in the forward direction, the pulling action of the second elastic element 409 on the slide rod 408 can make the rack 411 and the gear 303 re-engage, thereby driving the slide rod 408. 08 slides in the opposite direction to the side wall of the support plate 10. When the slide bar 408 slides in the opposite direction, it drives several push blocks 407 to move in the opposite direction. Several extension rods 405 slide in the opposite direction to several inclined surfaces 406. The first elastic element 401 pulls the slider 402 so that the slider 402 slides in the opposite direction along the guide rod 403, thereby driving the piston rod 404 and the piston plate 410 to move in the opposite direction. When the piston plate 410 moves in the opposite direction, it re-presses the air inside the core roller 201 from the air hole 203 into the annular air bladder 202, thereby driving the annular air bladder 202 to expand, so that the diameter of the annular air bladder 202 increases back to the first diameter value.

[0027] Please see Figure 5 In one embodiment, the outer wall of the annular airbag 202 is provided with a plurality of evenly distributed protrusions 204. When the annular airbag 202 rotates, the protrusions 204 move the nut, so that the nut can rotate smoothly, so that the water source supplied to the upper part of the annular airbag 202 via the water supply component can thoroughly rinse the nut.

[0028] In one embodiment, the protrusion 204 is integrally formed with the annular airbag 202.

[0029] Please see Figure 1 In one embodiment, a conveying assembly 50 is also provided between the two sets of support plates 10 and below the plurality of variable diameter cleaning rollers 20. The conveying assembly 50 is used to convey debris falling between the two adjacent sets of variable diameter cleaning rollers 20 and the cleaned nuts in separate sections, thereby realizing the separate collection of debris and nuts.

[0030] Please see Figure 1 , Figure 3 as well as Figure 7 In one embodiment, a second pulley 304 is fixedly disposed on the outside of the rotating shaft 302. The conveying assembly 50 includes two sets of shafts 502 and an annular mesh belt 501 sleeved on the two sets of shafts 502. The ends of the two sets of shafts 502 are rotatably connected to the inner wall of the support plate 10. A third pulley 503 is fixedly disposed on the outside of one set of shafts 502. The second pulley 304 and the third pulley 503 are connected by a first transmission belt 305.

[0031] When the rotating shaft 302 rotates in the forward direction, thereby driving several annular airbags 202 to rotate in the forward direction, the annular airbags 202 cause the nuts to rotate through friction. At this time, the debris washed off the surface of the nuts falls between two adjacent sets of annular airbags 202 and onto the upper part of the annular mesh belt 501. The rotation of the rotating shaft 302 in the forward direction also drives the second pulley 304 to rotate in the forward direction. When the second pulley 304 rotates in the forward direction, it drives the corresponding shaft 502 to rotate through the transmission action of the first transmission belt 305 and the third pulley 503. When this set of shafts 502 rotates, it can cooperate with another set of shafts 502 to drive the annular mesh belt 501 to rotate to the right. When the belt rotates to the right, any debris falling onto it can be removed from the right end of the annular mesh belt 501. When the rotating shaft 302 rotates in the opposite direction, the piston plate 410 draws air out of the annular airbag 202, causing the annular airbag 202 to collapse. The cleaned nuts fall between the two adjacent sets of annular airbags 202 and onto the upper part of the annular mesh belt 501. When the rotating shaft 302 rotates in the opposite direction, it can drive the second pulley 304 to rotate in the opposite direction. Through the transmission action of the first transmission belt 305 and the third pulley 503, the corresponding shaft 502 is driven to rotate in the opposite direction, thereby driving the annular mesh belt 501 to rotate to the left, so that the nuts on it can be removed from the left end of the annular mesh belt 501.

[0032] In one embodiment, a nut collection box is provided at the left end of the annular mesh belt 501, and a debris collection box is provided at the right end of the annular mesh belt 501.

[0033] When the annular mesh belt 501 rotates to the right, debris detaches from the right end of the annular mesh belt 501 and falls into the debris collection box, thus collecting the debris. When the annular mesh belt 501 rotates to the left, nuts detach from the left end of the annular mesh belt 501 and fall into the nut collection box, thus collecting the nuts.

[0034] In one embodiment, the first elastic element 401 and the second elastic element 409 can be springs or metal sheets, and there is no limitation here.

[0035] In one embodiment, the water supply assembly includes a water pump, a water pipe, and a nozzle. The water pipe is arranged above a plurality of variable diameter cleaning rollers 20, and the nozzle is installed at the bottom of the water pipe. The water pump is connected to the water pipe and pumps water into the water pipe, and then sprays it onto the upper part of the plurality of variable diameter cleaning rollers 20 by the nozzle to rinse the nuts.

[0036] In this embodiment of the invention, initially, the diameter of the variable diameter cleaning rollers 20 is a first diameter value. At this time, the distance between two adjacent sets of variable diameter cleaning rollers 20 is smaller than the diameter of the macadamia nut. When batch cleaning of macadamia nuts is required, the macadamia nuts to be cleaned can be placed on top of the variable diameter cleaning rollers 20. Since the distance between two adjacent sets of variable diameter cleaning rollers 20 is smaller than the diameter of the macadamia nut, the nuts can act between the two adjacent sets of variable diameter cleaning rollers 20 and cannot fall between them. Subsequently, water is supplied to the top of the variable diameter cleaning rollers 20 through the water supply component. At the same time, the drive component 30 drives the variable diameter cleaning rollers 20 to rotate synchronously. When the variable diameter cleaning rollers 20 rotate synchronously, they apply friction to the nuts, causing the nuts to rotate between the two adjacent sets of variable diameter cleaning rollers 20. Simultaneously, the variable diameter cleaning rollers 20 clean the surface of the nuts. The process involves grinding away impurities from the surface of the nuts, combined with the rinsing effect of water, to automatically clean the nuts. After the impurities are removed from the nut surface, they flow down between two adjacent sets of variable diameter cleaning rollers 20 with the water, completely separating the impurities from the nuts. After the nuts are cleaned, the diameter of several variable diameter cleaning rollers 20 is adjusted by the adjusting component 40, reducing the diameter of the rollers to a second diameter value. At this time, the distance between two adjacent sets of variable diameter cleaning rollers 20 increases to a value greater than the diameter of the nuts. The cleaned nuts can then fall between the two adjacent sets of variable diameter cleaning rollers 20, thus achieving automatic nut discharge. Compared with existing technologies, this method can achieve automatic cleaning and automatic discharge of macadamia nuts. Furthermore, the cleaning process can apply a grinding method to the macadamia nuts, ensuring that impurities are smoothly removed from the nut surface. It has the advantages of good cleaning effect and high cleaning efficiency.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
