Description

Technical Field

[0001] The utility model belongs to the technical field of nut processing equipment, and particularly relates to a nut shelling and screening machine. Background Art

[0002] In the nut processing industry, nut shelling is a crucial link. With the progress of technology and the development of automation technology, traditional nut shelling methods have gradually been replaced by mechanized and automated shelling equipment. However, after the existing nut shelling equipment shells the nuts, in order to facilitate the subsequent grading and selling of the kernels, the kernels need to be screened and graded. The existing devices have certain defects when in use. For example, in a Chinese patent with the publication number "CN 218945567 U", a nut grading and shelling screening machine is disclosed. The device includes a shelling machine. One outer wall of the shelling machine is fixedly connected with a support frame. A feed cylinder is fixedly connected to the support frame. A plurality of feet are fixedly connected to the bottom of the shelling machine. A fruit shell discharge port is arranged below the shelling machine. A kernel discharge port is arranged on the other outer wall of the shelling machine. An inclined plate is arranged below the kernel discharge port. One end of the inclined plate is rotatably connected to a support rod. The support rod is fixedly connected to a base. The other end of the support rod is rotatably connected to a top rod. When the device works, the motor drives the residual wheel to rotate. The residual wheel cooperates with the tooth block to drive the top rod to move up and down. In this way, the kernels on the inclined plate can vibrate up and down when flowing. Then, the small kernels can be collected in the small kernel collection box by using the through holes, and the remaining large kernels will flow into the large kernel collection box. However, when screening the kernels, since it is vibration screening, there is a high probability that the kernels will directly fall off the device without being screened, increasing the screening difficulty of the kernels and reducing the screening efficiency of the kernels. Moreover, the specifications for screening the kernels are fixed when the device is in use and cannot be adjusted according to actual needs, so the application range of the device has limitations.

Specific implementation manner

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 - 7 As shown, the present invention provides the following technical solution: a nut hulling and screening machine, including a hulling component for hulling nuts to produce kernels and nut shells, and a screening component for screening the kernels. The screening component is communicated with the hulling component. The screening component includes a housing part. Inside the housing part, two driving rollers 19 are rotatably connected counterclockwise. A conveyor belt 20 is sleeved between the two driving rollers 19. A plurality of loading plates 21 are fixedly connected in a circular array on the outer side of the conveyor belt 20. A storage space for storing kernels is formed between two adjacent loading plates 21. And a first discharge port for discharging small kernels and a second discharge port for discharging large kernels are formed on the housing part. Through the movement of the conveyor belt 20, the storage space sequentially passes through the first discharge port and the second discharge port and is sequentially communicated with the first discharge port and the second discharge port.

[0027] In this embodiment, when a person needs to screen nuts, the nuts to be processed are added to the inside of the hulling component. The nuts are hulled by the hulling component. After the nuts are hulled, they become kernels. The kernels are conveyed to the screening component by the hulling component. Through the guidance of the screening component, the kernels fall into the storage space between two adjacent loading plates 21. By rotating the driving rollers 19, the driving rollers 19 drive the conveyor belt 20 to rotate. The conveyor belt 20 drives the loading plates 21 to move, thereby driving the kernels to move inside the housing part, so that the kernels sequentially pass through the first discharge port and the second discharge port. When the kernels pass through the first discharge port, small kernels are discharged through the first discharge port, and large kernels remain in the storage space. After the small kernels are discharged, the conveyor belt 20 continues to drive the loading plates 21 to move, so that the large kernels are discharged through the second discharge port, thus completing the hulling and screening of the nuts.

[0028] Specifically, in one embodiment, regarding the above housing part:

[0029] As Figures 1 - 6 shown, the housing part includes a housing 5. An inner cavity 18 is formed inside the housing 5, and one side of the housing 5 is open to form a second discharge hole 11. A through first discharge hole 13 is provided at the bottom of the housing 5. Both the first discharge hole 13 and the second discharge hole 11 communicate with the inner cavity 18. A screening part is installed inside the first discharge hole 13. A driving roller 19 is rotatably connected inside the inner cavity 18, and a feed hole 12 for adding nuts is provided at the top of the housing 5. A support rod 6 for supporting itself is fixedly connected to the housing 5;

[0030] A motor 7 is fixedly connected to the housing 5, and the output end of the motor 7 is connected to one of the driving rollers 19;

[0031] The housing 5 is inclined, and the horizontal height of the second discharge hole 11 is at the lowest position on the housing 5.

[0032] In this embodiment, the nuts to be processed are added to the inside of the shelling member. The nuts are shelled by the shelling member. After the nuts are shelled, they become nuts. The nuts are conveyed to the feed hole 12 by the shelling member. The nuts are guided through the feed hole 12 so that the nuts fall into the storage space between two adjacent feeding plates 21. By the operation of the motor 7, the motor 7 drives the driving roller 19 to rotate in the inner cavity 18 inside the housing 5. The driving roller 19 drives the conveyor belt 20 to rotate. The conveyor belt 20 drives the feeding plate 21 to move, thereby driving the nuts to move inside the housing part, so that the nuts pass through the first discharge hole 13 and the second discharge hole 11 in sequence. When the nuts pass through the first discharge hole 13, the nuts are screened by the screening part on the first discharge hole 13, so that the small nuts are discharged from the first discharge hole 13, and the large nuts remain in the storage space. After the small nuts are discharged, the conveyor belt 20 continues to drive the feeding plate 21 to move, so that the large nuts are discharged through the second discharge hole 11, thus completing the shelling and screening of the nuts.

The conveyor belt 20 drives the feeding plate 21 to continue to move, and then the conveyor belt 20 and the feeding plate 21 drive the small nuts to be discharged through the second discharge hole 11, thereby completing the shelling and screening of the nuts. When it is necessary to change the specification of the screened nuts, the baffle 10 is rotated to separate the baffle 10 from the bottom plate 15, and the bottom plate 15 and the screen 17 are taken out of the first discharge hole 13, and then the bottom plate 15 and the screen 17 can be replaced, and nuts of different specifications can be screened.
