Technical Field

[0001] The utility model relates to the field of food processing, in particular to a device for chopping large-particle nuts. Background Art

[0002] Nut choppers are mainly used for chopping beans, nuts (such as peanuts, almonds, walnuts, hazelnuts, chestnuts) and other materials of different sizes in the food processing industry.

[0003] Existing nut choppers are usually straight knife choppers, which prevent nuts from being placed on a conveyor belt through a feed hopper, and then convey the nuts through the conveyor belt, and then use a straight knife assembly to move up and down to chop the nuts;

[0004] In actual application, large particles of raw materials such as walnuts are easily accumulated between the feed hopper and the straight knife assembly, and are difficult to enter the straight knife assembly, or even cannot enter the straight knife assembly, resulting in the inability to chopped large particles of raw materials. In addition, since many large particles cannot enter the straight knife assembly through the conveyor belt, the chopping efficiency is also low. Summary of the invention

[0005] The utility model aims to solve the problem that the straight blade shredder in the prior art cannot shred large-particle raw materials, and since many large particles cannot enter the straight blade assembly through the conveyor belt, the shredding efficiency is also low. A shredding device for large-particle nuts is proposed. By arranging a roller at the lower end of the hopper, the large-particle material can be preliminarily shredded first, thereby avoiding the problem that the large-particle material cannot enter the shredding unit.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A large-particle nut chopping device comprises a feeding unit, a chopping unit and a frame, wherein a conveyor belt is arranged on the frame, and the feeding unit is located above the conveyor belt;

[0008] The feeding unit comprises a silo and two rotating shafts, the silo is located above the two rotating shafts, a discharge port is arranged at the bottom of the silo, a roller is arranged on the outer side of each rotating shaft, the ends of the two rotating shafts are connected to the frame through a mounting plate, a strip hole is opened on the mounting plate, one end of the rotating shaft passes through the strip hole and is connected to a bearing seat, and an adjustment component 1 is arranged on one side of the bearing seat;

[0009] The shredding unit is located on one side of the feeding unit, and the shredding unit includes a driving assembly, a connecting rod and a knife group. The driving assembly is connected to one end of the connecting rod through an eccentric structure, and the other end of the connecting rod is connected to the knife group. The knife group is located above the conveyor belt, and the connecting rod drives the knife group to move up and down.

[0010] Furthermore, the adjustment component 1 includes an adjustment plate and an adjustment rod, the adjustment plate is provided with a threaded hole, the outer side of the adjustment rod is provided with a thread matching the threaded hole, one end of the adjustment rod is rotatably connected to the bearing seat, and the other end of the adjustment rod is provided with a handle after passing through the threaded hole, and the position of the bearing seat can be adjusted by turning the handle.

[0011] Furthermore, a scraper is provided on one side of the roller, and the scraper can scrape off the material on the surface of the roller.

[0012] Furthermore, both ends of the scraper are connected to the mounting plate through an adjusting component 2, and the adjusting component 2 has the same structure as the adjusting component 1. The distance between the scraper and the surface of the roller can be adjusted through the adjusting component 2.

[0013] Furthermore, the number of the shredding units is two, and the two shredding units are arranged side by side at one side of the feeding unit.

[0014] Furthermore, the two rotating shafts are connected via gears.

[0015] Furthermore, a box is arranged outside the mounting plate to protect structures such as the roller and scraper inside the box.

[0016] Through the above technical solution, the beneficial effects of the utility model are:

[0017] The utility model arranges a roller at the lower end of the silo so that large-particle nuts are initially chopped by the roller and then further chopped by a chopping unit. Compared with the prior art, large-particle nuts can be chopped and the problem of low efficiency caused by the inability of the chopping unit to chopped large-particle nuts is avoided.

[0018] The utility model can adjust the speed of the rollers and the distance between the two rollers, so as to cut large-particle nuts into different material sizes required by the shredding unit, which is convenient for the shredding unit to perform shredding. The material on the surface of the roller can be scraped off by arranging a scraper and adjusting component 2. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The feeding unit comprises a silo 2 and two rotating shafts 3, the silo 2 is located above the two rotating shafts 3, a discharge port is provided at the bottom of the silo 2, a roller cutter 4 is provided on the outer side of the rotating shafts 3, the ends of the two rotating shafts 3 are connected to the frame 1 through a mounting plate, a strip hole is provided on the mounting plate, one end of the rotating shaft 3 passes through the strip hole and is connected to a bearing seat, and an adjustment component 5 is provided on one side of the bearing seat;

[0030] The shredding unit is located on one side of the feeding unit, and the shredding unit includes a driving assembly 6, a connecting rod 7 and a knife group 8. The driving assembly 6 is connected to one end of the connecting rod 7 through an eccentric structure, and the other end of the connecting rod 7 is connected to the knife group 8. The knife group 8 is located above the conveyor belt 9, and the connecting rod 7 drives the knife group 8 to move up and down.

[0031] In addition, the adjustment component 5 includes an adjustment plate and an adjustment rod 502, the adjustment plate is provided with a threaded hole, the outer side of the adjustment rod 502 is provided with a thread matching the threaded hole, one end of the adjustment rod 502 is rotatably connected to the bearing seat, and the other end of the adjustment rod 502 is provided with a handle 501 after passing through the threaded hole. By rotating the handle 501, the position of the bearing seat can be adjusted, thereby adjusting the distance between the two rollers 4, so that large-particle nuts can be cut into different material sizes required by the shredding unit.

[0032] Specifically, a scraper 10 is provided on one side of the roller cutter 4 , and the scraper 10 can scrape off the materials on the surface of the roller cutter 4 to prevent the materials from sticking to the roller cutter 4 .

[0033] In this embodiment, both ends of the scraper 10 are connected to the mounting plate through an adjusting component 11. The adjusting component 11 has the same structure as the adjusting component 1 5. The distance between the scraper 10 and the surface of the roller 4 can be adjusted through the adjusting component 11 to ensure that the scraper 10 can scrape off the material on the roller 4.

[0034] In this embodiment, the shredding units are provided in two numbers, and the two shredding units are arranged side by side on one side of the feeding unit, which improves the shredding efficiency of the knife group 8 and can further reduce the size of the shredded nuts. The number of blades in the knife group 8 can also be reduced to meet the requirements of shredding nuts of different sizes.

At present, this shredder can shred larger nut materials such as walnuts. The shredder is first shredded by the roller cutter 4 component and then shredded by two groups of shredding units. The shredding efficiency is higher than that of the original straight knife shredder. In addition, the application can also adjust the operating speed of the roller cutter 4 and the transportation speed of the conveyor belt 9 by frequency conversion speed regulation, adjust the gap between the two roller cutters 4 by adjusting the hand wheel, and form different combinations by increasing or decreasing the number of straight knives in the straight knife group 8, so as to meet the requirements of shredding different types of large-sized nuts to various sizes.

[0040] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention.
