Description

Technical Field

[0001] This utility model specifically relates to a fruit sorting device for nut processing, belonging to the field of nut processing technology. Background Technology

[0002] Nut processing refers to removing the outer shell of fruits by manual or mechanical methods to make kernels. The process of processing nuts into kernels can generally be divided into: raw material processing (selection, washing, drying, grading, etc.), shelling, drying, peeling, grading, and packaging. However, before nut processing, it is often necessary to sort the nuts. The device for sorting nuts usually includes a separating drum. The drum wall is equipped with multiple sieve holes, and the diameter of the sieve holes is set from small to large along the feeding direction, so that nuts of different sizes can be sorted out.

[0003] Currently, during the processing of nuts using fruit sorting devices, the nuts that need to be sorted may contain leaves. These leaves may carry mold spores (such as aflatoxin), insect eggs, or pesticide residues, which can contaminate the entire batch of nuts and cause food safety issues. Moreover, the nut sorting process may cause dust to fill the workshop, which can easily reduce the environmental quality of the workshop. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a fruit sorting device for nut processing, which can effectively remove and purify light impurities (leaves, dust) and dust raised during the sorting process, thereby maintaining a clean working environment.

[0005] A fruit sorting device for nut processing includes a sorting frame, a first screen, and a mounting shell. A first connecting pipe is disposed through one side of the mounting shell, and an assembly shell is disposed through the other end of the first connecting pipe. An exhaust assembly is disposed through one side of the mounting shell below the first connecting pipe. Two sets of exhaust shells are disposed through the outer side of the sorting frame. The exhaust assembly consists of an installation cylinder and an exhaust fan. A second connecting pipe is disposed through one side of the exhaust shell and communicates with the interior of the mounting shell.

[0006] Preferably, the top of the sorting frame is provided with two sets of guide rods, which move through the plate at the top of the No. 1 screen, and the front of the sorting frame is provided with a control box.

[0007] Preferably, a second screen is detachably installed inside the first screen, a locking plate is provided at the top of the second screen, a swing plate is rotatably installed at the top of the locking plate, an insert rod is inserted through the inside of the swing plate, and a spring is provided on the outside of the insert rod.

[0008] Preferably, a third screen is provided inside the second screen, and an assembly plate is provided at the top of the third screen, and the assembly plate is adapted to be inserted into the groove at the top of the card plate.

[0009] Preferably, the diameter of the sieve holes inside the No. 1 sieve, No. 2 sieve, and No. 3 sieve is set from small to large.

[0010] Preferably, a feed shell is provided on one side of the sorting rack via a bracket, and the assembly shell is connected to the lower surface of the feed shell.

[0011] Preferably, the mounting housing has a detachable mounting frame inside, and the mounting frame has a filter screen inside.

[0012] Preferably, the outer sides of the two sets of guide rods are movably fitted with mounting brackets, the mounting brackets are equipped with fans inside, and the mounting brackets are provided with protective shells on the side facing the assembly shell.

[0013] Beneficial effects:

[0014] By incorporating components such as exhaust housings and assembly housings, a negative pressure airflow network is formed through connecting pipes No. 1 and No. 2. When the exhaust assembly is activated, it can draw in light impurities (leaves, dust) from the assembly housing and exhaust housing into the mounting housing. The impurities are filtered and stored using a filter screen inside the mounting frame. The two sets of exhaust housings are connected to the inner wall of the sorting rack, directly extracting dust raised during the sorting process and maintaining a clean working environment. The fan is installed on a mounting rack that can move along the guide rod, providing auxiliary airflow and enhancing the impurity separation effect.

[0015] The mounting frame is designed with components such as a mounting frame that can be inserted into and detached from the mounting shell. The inner wall of the mounting shell is equipped with slats to support the mounting frame. The filter inside the mounting frame can filter out leaves, dust, and impurities that enter the mounting shell. In the later stages, the filter can be removed simply by pulling the mounting frame out of the mounting shell, making it easy to clean the filter later. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 As shown, a fruit sorting device for nut processing;

[0025] The system includes a sorting frame 1, a first screen 3, and a mounting shell 14. A first connecting pipe 13 is installed through one side of the mounting shell 14, and an assembly shell 12 is installed through the other end of the first connecting pipe 13. An exhaust assembly 17 is installed through one side of the mounting shell 14 below the first connecting pipe 13. Two sets of exhaust shells 18 are installed through the outer side of the sorting frame 1. The exhaust assembly 17 consists of an installation cylinder and an exhaust fan. A second connecting pipe 19 is installed through one side of the exhaust shell 18 and is connected to the interior of the mounting shell 14. Mounting brackets 20 are movably sleeved on the outer side of the two sets of guide rods 2. A fan 21 is installed inside the mounting bracket 20. A protective shell 22 is installed on the side of the mounting bracket 20 facing the assembly shell 12.

[0026] The exhaust assembly 17 consists of an installation cylinder and an exhaust mechanism. It forms a negative pressure airflow network through the first connecting pipe 13 and the second connecting pipe 19, which can suck up light impurities (leaves, dust) from the assembly shell 12 and the exhaust shell 18 into the installation shell 14. The interior of the two sets of exhaust shells 18 is connected to the inner wall of the sorting rack 1, directly extracting the dust raised during the sorting process and keeping the working environment clean. The fan 21 is installed on the installation rack 20, which can move along the guide rod 2, to provide auxiliary airflow and enhance the impurity separation effect. The protective shell 22 prevents nut particles from entering the fan 21 and extends the equipment life.

[0027] The top of the sorting frame 1 is provided with two sets of guide rods 2, which move through the plate at the top of the No. 1 screen 3. The front of the sorting frame 1 is provided with a control box 23. The side of the sorting frame 1 is provided with a feed shell 11 through a bracket. The assembly shell 12 is connected to the lower surface of the feed shell 11. The interior of the mounting shell 14 is provided with a detachable mounting frame 15, and the interior of the mounting frame 15 is provided with a filter screen 16.

[0028] The sorting frame 1 forms the main frame of the device, supporting the sorting components. The guide rod 2 passes through the plate at the top of the No. 1 screen 3, enabling the guide rod 2 to guide the movement of the No. 1 screen 3 and ensure its stability during use. Furthermore, the guide rod 2 passes through the interior of the mounting frame 20, allowing for linear positioning of the mounting frame 20 and adjustment of the operating position of the blower 21. The control box 23 integrates an electrical control unit, adjusting parameters such as the power of the blower 21 and the exhaust assembly 17 to achieve automated operation. The feed housing 11 is mounted on a bracket. The sorting rack 1 is positioned on one side, and the discharge port of the feed shell 11 after installation is located above the No. 3 screen 9, ensuring that the nuts fall evenly into the No. 3 screen 9 and avoid accumulation. The mounting frame 15 is inserted into the interior of the detachable mounting shell 14. The inner wall of the mounting shell 14 is provided with slats for supporting the mounting frame 15. The filter screen 16 inside the mounting frame 15 can filter leaves, dust and impurities entering the mounting shell 14. In the later stage, the mounting frame 15 can be pulled out of the mounting shell 14 to remove the filter screen 16, which is convenient for cleaning the filter screen 16 later.

[0029] The No. 1 screen 3 has a detachable No. 2 screen 4 inside. The top of the No. 2 screen 4 has a locking plate 5. The top of the locking plate 5 has a rotatable swing plate 6. The swing plate 6 has a through rod 7 inside. The outside of the through rod 7 has a spring 8. The No. 2 screen 4 has a No. 3 screen 9 inside. The top of the No. 3 screen 9 has an assembly plate 10. The assembly plate 10 is adapted to be inserted into the groove at the top of the locking plate 5. The diameter of the screen holes inside the No. 1 screen 3, No. 2 screen 4 and No. 3 screen 9 is set from small to large.

[0030] The sieve hole design of sieve 3 (No. 1), sieve 4 (No. 2), and sieve 9 (No. 3) features a layered arrangement of sieve hole diameters from small to large (e.g., sieve 3 removes large impurities, sieve 4 sorts medium-sized nuts, and sieve 9 filters small particles). This allows for precise grading of nuts by size. The assembly plate 10 is fitted with a card that passes through the groove at the top of the carding plate 5. Then, the angle of the swing plate 6 is adjusted, and the spring 8 on the outside of the insertion rod 7 applies elastic tension to the insertion rod 7. The insertion rod 7 can penetrate the assembly plate 10 and insert into the corresponding hole in the carding plate 5, thus locking and positioning the assembly plate 10 and the carding plate 5 after assembly. This facilitates quick replacement or cleaning of the sieves and adapts to different nut varieties.
