[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 5As shown, a nut roasting and screening machine according to an embodiment of the present invention includes a driving seat 1; an outer cylinder 2 is fixedly connected to one side of the driving seat 1; a support seat 3 is installed on the side of the outer cylinder 2 away from the driving seat 1; a rotating ring 4 is rotatably connected to the side of the driving seat 1 close to the outer cylinder 2, and the rotating ring 4 is driven by a servo motor through a gear set; an inner cylinder 5 is fixedly connected to the side of the driving ring close to the outer cylinder 2; a guide plate 6 is fixedly connected to the axis of the inner cylinder 5 on the driving seat 1, and the guide plate 6 is U-shaped; a plurality of evenly arranged through holes 7 are opened on the surface of the inner cylinder 5; The top and bottom of the outer cylinder 2 are fixedly connected with air guide pipes 8, and the air guide pipes 8 are connected to the external hot air system; the side of the driving seat 1 away from the inner cylinder 5 is fixedly connected with a feeding pipe 9; the side of the outer cylinder 2 close to the support seat 3 is installed with a discharging assembly; the discharging assembly is used to discharge the material in the inner cylinder 5; when working, in order to screen the nuts during baking, the embodiment of the present invention can be used. First, the user needs to introduce the nuts to be baked into the inner cylinder 5 through the feeding pipe 9, and then the user starts the rotating ring 4, which will drive the inner cylinder 5 to rotate, and the rotating inner cylinder 5 will The nuts inside it are driven to rotate together, and since the mass of the full nuts is greater than that of the shriveled nuts, when the full nuts follow the rotation of the inner cylinder 5, the nuts of different masses are subjected to different centrifugal effects when rotating in the inner cylinder, so the full nuts with large mass will not rotate to the top of the guide plate 6, but will fall to the bottom of the inner cylinder 5 again, while the shriveled nuts with small mass will follow the inner cylinder 5 to rotate to the top of the guide plate 6, and then the shriveled nuts will fall and fall into the inside of the guide plate 6, thus completing the screening of the nuts, and finally discharged by the discharge assembly While the nuts are being screened, the external hot air system will introduce hot air from the top of the inner cylinder 5 into the interior of the inner cylinder 5 through the air guide pipe 8 and the through holes 7 on the surface of the inner cylinder 5, and roast the nuts inside the inner cylinder 5. The rotation of the inner cylinder 5 will drive the nuts to turn inside it, and then screen out nuts of unqualified quality according to the quality of the nuts. At the same time, in the process of the nuts turning inside the inner cylinder 5, the hot air introduced into the inner cylinder 5 by the air guide pipe 8 can also roast the nuts. Therefore, the nuts can be screened while being roasted, thereby improving the processing efficiency.

[0023] like Figure 3 、 Figure 4 and Figure 7As shown, the discharging assembly includes a spiral feeding rod 10; the spiral feeding rod 10 is rotatably connected to the driving seat 1 and is located inside the guide plate 6; the spiral feeding rod 10 is driven by a servo motor; a material port 11 is provided on the surface of the support seat 3 at a position corresponding to the guide plate 6; the support seat 3 is fixedly connected to the outer cylinder 2 and the guide plate 6, and is rotatably connected to the spiral feeding rod 10 and the inner cylinder 5; a separation tube 12 is fixedly connected to the surface of the support seat 3 at a position corresponding to the material port 11; a material port 2 13 is provided on the surface of the support seat 3 near the bottom; The surface of the support seat 3 is fixedly connected to the discharge pipe 14 at the position corresponding to the material port 2 13; during operation, when unloading is required, the servo motor will drive the spiral feeding rod 10 to rotate, and the spiral feeding rod 10 will drive the nuts in the guide plate 6 to move toward the material port 11, and finally be discharged from the separation pipe 12, while the nuts inside the inner cylinder 5 are swept into the material port 13 by the user, and finally discharged from the discharge pipe 14, thereby separating the unqualified nuts from the qualified nuts and discharging them separately, which not only realizes the discharge of the unqualified nuts and the qualified nuts, but also avoids the two being mixed together again.

[0024] like Figures 1 to 2 As shown, a lifting seat 15 is provided on the side where the driving seat 1 and the support seat 3 are away from each other; the two lifting seats 15 are respectively located on the side where the driving seat 1 and the support seat 3 are away from each other; a pair of hydraulic rods 16 are fixedly connected to the side where the two lifting seats 15 are close to each other; the telescopic ends of the paired hydraulic rods 16 are commonly fixedly connected to a connecting plate 17, and the connecting plate 17 is arranged in a Z shape; the bottoms of the two connecting plates 17 are rotatably connected to the driving seat 1 and the support seat 3 respectively; the connecting plate 17 close to the separation tube 12 is provided with a makeshift groove 18 at the corresponding position of the separation tube 12, and the makeshift groove 18 passes through the connecting plate 17; during work, in order to facilitate the user to unload, the user can start the drive The hydraulic rod 16 on one side of the seat 1, at this time the hydraulic rod 16 will drive the driving seat 1 to rise through the connecting plate 17, so that the end of the inner cylinder 5 close to the driving seat 1 is lifted, and the material in the inner cylinder 5 will slide toward the direction of the material port 1 11 and the material port 2 13, thereby facilitating the outflow of the material inside the inner cylinder 5, and the yield groove 18 at the connecting plate 17 can also prevent the separation tube 12 from colliding with the lifting seat 15, thereby ensuring that the branch tube can discharge the material normally. At the same time, during the process of roasting nuts, the hydraulic rods 16 at the two lifting seats 15 will drive one side of the inner cylinder 5 to rise in turn through the hydraulic rod 16, thereby driving the nuts in the inner cylinder 5 to slide, avoiding the nuts from gathering together, thereby improving the roasting effect of the nuts.

[0025] like Figure 7As shown, two pairs of symmetrically arranged baffles 19 are fixedly connected to the inner wall of the outer cylinder 2; the two pairs of baffles 19 are respectively located at the top and bottom of the inner cylinder 5; the top and bottom air ducts 8 are respectively located between the top pair of baffles 19 and the bottom pair of baffles 19; during operation, when hot air is introduced into the inner cylinder 5 from the top air duct, due to the restriction of the baffle 19, most of the hot air will be introduced into the inner cylinder 5 from the top. At this time, the deflated fruits that move to the top as the inner cylinder 5 rotates will be blown off by the hot air and fall into the guide plate 6, thereby preventing some deflated fruits from getting stuck in the through-hole 7, which will lead to a decrease in the screening effect.

[0026] like Figures 4 to 6 As shown, a guide plate 20 is fixedly connected to the side of the guide plate 6 away from the inner cylinder 5; the guide plate 20 is arranged in an arc shape and is convex in the middle; a plurality of evenly arranged feed ports 21 are provided on both sides of the guide plate 20; a plurality of evenly arranged exhaust holes 22 are provided on the surface of the guide plate 6 and at the top of the guide plate 20; during operation, when hot air is introduced into the inner cylinder 5 from the top of the inner cylinder 5, the hot air will blow toward the top of the guide plate 6 and be guided by the guide plate 20 to the exhaust holes 22 on the surface of the guide plate 6, thereby avoiding the hot air from being concentrated on the top of the inner cylinder 5, thereby affecting the nut roasting efficiency at the bottom of the inner cylinder 5, and the shriveled fruit falling on the top surface of the guide plate 20 will slide along the guide plate 20 to the feed port 21 and finally fall into the inner guide plate 6.

[0027] like Figures 5 and 6 As shown, the surface of the guide plate 20 is fixedly connected with a guide plate 1 23 on the side adjacent to the feed port 21, and the guide plate 1 23 is arranged in a triangular prism shape; the side of the guide plate 1 23 away from the guide plate 6 is fixedly connected with a guide plate 24, and the guide plate 24 is arranged in a triangular pyramid shape; during operation, when the shriveled fruits fall on the surface of the guide plate 6, the shriveled fruits will slide to the sides of the guide plate 20, and some of the shriveled fruits will directly fall into the inside of the guide plate 6 through the feed port 21, while some of them will slide to the guide plate 1 23 between the feed port 21, and will be guided by the guide plate 1 23 to the guide plate 24, and introduced into the feed port 21 by the guide plate 24, thereby avoiding the accumulation of shriveled fruits on the surface of the guide plate 20.

[0028] like Figures 7 to 9As shown, a mounting box 25 is fixedly connected between the inner wall of the outer cylinder 2 and the two baffles 19 on one side; a plurality of evenly arranged partitions 26 are fixedly connected to the interior of the mounting box 25; a push plate 27 is slidably connected in the space enclosed by the inner wall of the mounting box 25 and each partition 26; a one-way valve 28 is installed on the surface of the push plate 27, and the push plate 27 is driven by a driving assembly; a plurality of evenly arranged air outlet holes 29 are opened on the side of the mounting box 25 close to the inner cylinder 5; a side of the mounting box 25 away from the air outlet holes 29 is provided. The end is fixedly connected with a conduit 30, and the conduit 30 is located at the end away from the air outlet 29; during operation, when the inner cylinder 5 rotates, the push plate 27 in the mounting box 25 will be driven by the driving component to move back and forth in the space surrounded by the partition 26 and the mounting box 25, and then continuously suck the hot air through the conduit 30 and the one-way valve 28, and blow the hot air out from the air outlet 29 and blow it to the surface of the inner cylinder 5, so that a part of the hot air is directly blown to the nuts from the side, thereby improving the heating efficiency of the nuts and shortening the time required for baking the nuts.

[0029] like Figures 7 to 9 As shown, the driving assembly includes a roller 31; a turntable 32 is fixedly connected between the push plate 27 and the mounting box 25, and the turntable 32 is connected to the roller 31 through a gear set; the surface of the turntable 32 is rotatably connected to a push rod 33; the push rod 33 is rotatably connected to a push block 34 at one end away from the turntable 32, and the push block 34 is slidably connected to the partition 26; the push block 34 is fixedly connected to the push plate 27 at one end away from the push rod 33; during operation, when the inner cylinder 5 rotates, the inner cylinder 5 will drive the roller 31 to rotate, and the roller 31 will drive the turntable 32 to rotate, and the turntable 32 will drive the push block 34 to slide back and forth through the push rod 33, and finally the push block 34 will drive the push plate 27 to slide back and forth, thereby completing the exhaust operation of the push plate 27, thereby eliminating the need to add an additional power source, reducing the cost of the embodiment of the present invention.

[0030] like Figures 7 to 9 As shown, a connecting frame 35 is fixedly connected to one side of the mounting box 25 close to the push plate 27; the air outlet 29 is located on the inner side of the connecting frame 35; a sealing film 36 is fixedly connected between the connecting frame 35 and the push plate 27; during operation, when the push plate 27 makes a reciprocating motion, the sealing film 36 between the push plate 27 and the connecting frame 35 can play a sealing role, so that most of the hot air can be discharged from the air outlet 29, thereby increasing the speed of the hot air discharge, so that it can contact the nuts faster, thereby further improving the baking efficiency of the nuts.

[0031] like Figures 4 and 5As shown, the bottom surface of the guide plate 6 is fixedly connected with a plurality of pairs of evenly arranged support rods 37; the ends of the paired support rods 37 away from the guide plate 6 are commonly fixedly connected with a flap 38; the bottom surface of the flap 38 is arranged in an arc shape and is adapted to the inner wall of the inner cylinder 5; during operation, when the inner cylinder 5 rotates, the support rods 37 on the bottom surface of the guide plate 6 and the flap 38 at its bottom will move relative to the inner cylinder 5, thereby colliding with the nuts in the inner cylinder 5, so that the nuts in the inner cylinder 5 are heated more evenly, thereby improving the effect of roasting the nuts.

[0032] During operation, in order to screen the nuts during baking, the embodiment of the present invention can be used. First, the user needs to introduce the nuts to be baked into the inner cylinder 5 through the feed pipe 9, and then the user starts the rotating ring 4. The rotating ring 4 will drive the inner cylinder 5 to rotate, and the rotating inner cylinder 5 will drive the nuts inside it to rotate together. Since the mass of full nuts is greater than that of shriveled and poor-quality nuts, when the full nuts follow the rotation of the inner cylinder 5, the centrifugal effects of nuts of different masses when rotating in the inner cylinder are different. Therefore, the full nuts with large mass will not rotate to the top of the guide plate 6, but will fall back to the bottom of the inner cylinder 5, while the shriveled and small-mass nuts will follow the inner cylinder 5. The cylinder 5 rotates to the top of the guide plate 6, thereby completing the screening of the nuts, and finally discharged by the discharge assembly. While the nuts are being screened, the external hot air system will introduce hot air from the top of the inner cylinder 5 into the interior of the inner cylinder 5 through the air guide pipe 8 and the through hole 7 on the surface of the inner cylinder 5, and bake the nuts inside the inner cylinder 5. The rotation of the inner cylinder 5 drives the nuts to turn inside it, and then screens out nuts of unqualified quality according to the quality of the nuts. At the same time, in the process of the nuts turning inside the inner cylinder 5, the hot air introduced into the inner cylinder 5 by the air guide pipe 8 can also bake the nuts. Therefore, the nuts are screened while being baked, thereby improving the processing efficiency.

[0033] When unloading is required, the servo motor will drive the spiral feeding rod 10 to rotate, and the spiral feeding rod 10 will drive the nuts in the guide plate 6 to move toward the material port 11, and finally be discharged from the separation tube 12, while the nuts inside the inner cylinder 5 are swept into the material port 13 by the user, and finally discharged from the discharge pipe 14, thereby the unqualified nuts and the qualified nuts are discharged separately, which not only realizes the discharge of unqualified nuts and qualified nuts, but also avoids the two being mixed together again.

[0034] In order to facilitate the user's unloading, the user can start the hydraulic rod 16 near the side of the driving seat 1. At this time, the hydraulic rod 16 will drive the driving seat 1 to rise through the connecting plate 17, so that the end of the inner cylinder 5 close to the driving seat 1 is lifted. At this time, the material in the inner cylinder 5 will slide toward the direction of the material port 11 and the material port 2 13, thereby facilitating the outflow of the material inside the inner cylinder 5, and the yield groove 18 at the connecting plate 17 can also prevent the separation tube 12 from colliding with the lifting seat 15, thereby ensuring that the branch tube can discharge the material normally. At the same time, during the process of roasting nuts, the hydraulic rods 16 at the two lifting seats 15 will drive one side of the inner cylinder 5 to rise in turn through the hydraulic rod 16, thereby driving the nuts in the inner cylinder 5 to slide, avoiding the nuts from gathering together, thereby improving the roasting effect of the nuts.

[0035] When hot air is introduced into the inner cylinder 5 from the air duct at the top, due to the restriction of the baffle 19, most of the hot air will be introduced into the inner cylinder 5 from the top. At this time, the deflated fruits that move to the top as the inner cylinder 5 rotates will be blown off by the hot air and fall into the guide plate 6, thereby preventing some deflated fruits from getting stuck in the through holes 7, which would reduce the screening effect.

[0036] When the hot air is introduced into the inner cylinder 5 from the top of the inner cylinder 5, the hot air will blow toward the top of the guide plate 6 and be guided by the guide plate 20 to the exhaust holes 22 on the surface of the guide plate 6, thereby preventing the hot air from being concentrated on the top of the inner cylinder 5, thereby affecting the roasting efficiency of the nuts at the bottom of the inner cylinder 5. The shrunken fruits that fall on the top surface of the guide plate 20 will slide along the guide plate 20 to the feed port 21 and finally fall into the inside of the guide plate 6.

[0037] When the deflated fruits fall on the surface of the guide plate 6, they will slide to the two sides of the guide plate 20. Some of the deflated fruits will directly fall into the inside of the guide plate 6 through the feed port 21, while some of them will slide to the guide plate 1 23 between the feed port 21 and will be guided by the guide plate 1 23 to the guide plate 2 24 and introduced into the feed port 21 by the guide plate 2 24, thereby preventing the deflated fruits from accumulating on the surface of the guide plate 20.

[0038] When the inner cylinder 5 rotates, the push plate 27 in the mounting box 25 will be driven by the driving component to move back and forth in the space enclosed by the partition 26 and the mounting box 25, and then continuously suck the hot air through the conduit 30 and the one-way valve 28, and blow the hot air out from the air outlet 29 to the surface of the inner cylinder 5, so that part of the hot air is directly blown to the nuts from the side, thereby improving the heating efficiency of the nuts and shortening the time required for nut baking.

[0039] When the inner cylinder 5 rotates, the inner cylinder 5 drives the roller 31 to rotate, and the roller 31 drives the turntable 32 to rotate. The turntable 32 drives the push block 34 to slide back and forth through the push rod 33, and finally the push block 34 drives the push plate 27 to slide back and forth, thereby completing the exhaust operation of the push plate 27. Thereby, there is no need to add an additional power source, which reduces the cost of the embodiment of the present invention.

[0040] When the push plate 27 makes reciprocating motion, the sealing film 36 between the push plate 27 and the connecting frame 35 can play a sealing role, so that most of the hot air can be discharged from the air outlet 29, thereby increasing the speed of the hot air discharge, so that it can contact the nuts faster, thereby further improving the baking efficiency of the nuts.

[0041] When the inner cylinder 5 rotates, the support rod 37 on the bottom of the guide plate 6 and the flap 38 at its bottom will move relative to the inner cylinder 5, thereby colliding with the nuts in the inner cylinder 5, so that the nuts in the inner cylinder 5 are heated more evenly, thereby improving the effect on the nuts.
