Description

Technical Field

[0001] This utility model relates to the field of nut shelling technology, specifically a shelling device for testing nut foods. Background Technology

[0002] Nuts come in many varieties, including almonds, walnuts, cashews, and hazelnuts. During production, processing, and storage, nuts are susceptible to contamination or spoilage, such as mold, insect infestation, and chemical residues. Some nuts have additives added to mask their original flavor, which can conceal spoilage and mold. These harmful substances can seriously affect human health and even cause food poisoning. Nut inspection and testing can promptly identify and remove nuts with potential safety hazards, ensuring food safety.

[0003] A search revealed a Chinese patent document disclosing a shell-breaking device for detecting nuts [Application No.: CN202420091447.3]. This shell-breaking device for detecting nuts includes a shell, a cover, a piston, a cam, a bevel gear set, and a motor. The shell has an internal cavity with an opening on one side. The cover fits over the shell. A piston is located inside the shell, with a crushing part on its front end. A cam is located behind the piston and mounted on a shaft fixed inside the shell. The rotation of the cam drives the piston to move back and forth. A bevel gear set is also mounted on the cam shaft, connecting the motor and the cam shaft to transmit power to the piston, causing it to move back and forth. The crushing part of the piston and the cover squeeze each other to break the shells of the nuts.

[0004] The device disclosed in this patent requires rotation and disassembly to collect and remove nuts, which is inconvenient and increases the workload of staff, thus affecting the efficiency of subsequent testing and the convenience and shell-breaking efficiency of the device.

[0005] Meanwhile, when cracking nuts of different sizes, the entire device needs to be lifted up before it can be adjusted. The device is quite heavy, making it inconvenient to adjust and affecting its efficiency. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 1-5As shown, a shell-breaking device for testing nuts includes a protective shell 1. A squeezing mechanism 2 is installed inside the protective shell 1. Under the action of the squeezing mechanism 2, the nuts to be tested can be quickly shelled, facilitating subsequent testing by staff. A rotating shaft 3 is fixedly connected inside the protective shell 1. A movable block 4 is rotatably connected to the surface of the rotating shaft 3. The rotating shaft 3 passes through the interior of the movable block 4, allowing the movable block 4 to rotate around the rotating shaft 3. Limiting plates 5 are fixedly connected to two points on the top of the movable block 4. A connecting block 6 is provided on one side of the limiting plate 5. A limiting mechanism 7 is provided inside the cavity of the connecting block 6. A pressure plate 8 is fixedly connected to the surface, and a connecting block 6 supports the pressure plate 8, ensuring its stability during operation. Under the action of the limiting mechanism 7, the position of the pressure plate 8 can be adjusted to move it up and down, facilitating quick and easy changes in the distance between the extrusion mechanism 2 and the pressure plate 8. This allows the device to crack nuts of different sizes, adapting to various nut-cracking needs and avoiding the complex operation of frequent disassembly for different nut sizes. This improves the overall cracking efficiency and adaptability of the device. A drawer 9 is slidably connected to the inner cavity of the protective shell 1, allowing the pressure plate 8 to be adjusted under pressure. The broken nuts on the surface of plate 8 are collected. A moving mechanism 10 is installed inside the protective shell 1. A handle 11 is fixedly connected to the surface of drawer 9. Drawer 9 works in conjunction with the moving mechanism 10 and the handle 11. Under the action of the moving mechanism 10, pulling the handle 11 can tilt the surface of the pressure plate 8, causing the broken nuts on the surface of the pressure plate 8 to slide into drawer 9, quickly collecting the broken nuts on the surface of the pressure plate 8 and reducing the impact of the broken nuts on the subsequent shell-cracking effect. At the same time, the handle 11 can be used to pull drawer 9 out of the protective shell 1, making it convenient for workers to pick nuts from drawer 9. The process of picking and inspecting nuts improves the ease of use of the entire device. A sliding block 12 is fixedly connected to the surface of the drawer 9, and a sliding groove 13 is provided inside the protective shell 1. Under the action of the sliding block 12 and the sliding groove 13, the drawer 9 can be limited, making it more stable during the process of pulling out and putting in. A magnet 14 is fixedly connected to the inner cavity of the protective shell 1. The drawer 9 is made of iron. The magnet 14 and the drawer 9 work together. Under the action of the magnet 14, the drawer 9 can be attracted, reducing the shaking that may cause the drawer 9 to fall out of the inner cavity of the protective shell 1 during the use of the device, thus improving the stability of the device during use.

[0025] The limiting mechanism 7 includes limiting holes 71 located on two sides of the limiting plate 5. There are several limiting holes 71, which are used in pairs. A positioning frame 72 is slidably connected inside each limiting hole 71. Under the action of the limiting holes 71, the positioning frame 72 is limited, preventing it from easily shaking. A pressing shell 73 is fixedly connected to one side of the surface of the positioning frame 72. A moving column 74 is fixedly connected to the surface of the pressing shell 73. A compression spring 75 is fixedly connected to one end of the moving column 74. One end of the compression spring 75 is fixedly connected to the inner cavity of the connecting block 6. A pull rod 76 is slidably connected to the inner cavity of the pressing shell 73. One side of both the inner wall of the pull rod 76 and the inner wall of the pressing shell 73 are inclined. The inclined structure design allows the pull rod 76 to compress the extrusion shell 73 under the action of its surface shape. At the same time, with the cooperation of the moving column 74 and the compression spring 75, the moving column 74 can be moved into the inner cavity of the connecting block 6, causing the positioning frame 72 to disengage from the limiting hole 71. This allows the distance between the pressure plate 8 and the extrusion mechanism 2 to be adjusted. Under this action, the device can crack nuts of different types and sizes, reducing the need for frequent equipment changes and improving the applicability of the device. When the plane on one side of the pull rod 76 contacts the plane on the inner cavity side of the extrusion shell 73, the pull rod 76 and the extrusion shell 73 can be pressed against each other with the cooperation of the spring 75, so that the pull rod 76 will not move easily.

[0026] The moving mechanism 10 includes a rotating wheel 101 mounted on the inner surface of the drawer 9. The top of the rotating wheel 101 is lower than the bottom of the inner cavity of the rotating shaft 3. Under the action of the rotating wheel 101, the surface of the movable block 4 can be squeezed. The pressure generated can cause the movable block 4 to tilt the pressure plate 8, allowing the nuts broken on the surface of the pressure plate 8 to fall into the interior of the drawer 9 under the tilting action. This makes it convenient for inspectors to pick out the nuts for inspection, improving the ease of use of the device and effectively reducing the impact of broken nuts on the surface of the pressure plate 8 on the subsequent shelling effect, thus improving the shelling process of the device. For stability, fixed blocks 102 are fixedly connected to both sides of the movable block 4. A tension spring 103 is fixedly connected to the bottom of the fixed block 102. The other end of the 103 is fixedly connected to the inner wall of the protective shell 1. Under the action of the tension spring 103, the movable block 4 can spring back to its original position when the drawer 9 moves, so that it can remain stable. A positioning plate 104 is fixedly connected inside the protective shell 1. With the cooperation of the positioning plate 104 and the fixed block 102, the movable block 4 can be limited and supported, so that the position of the pressure plate 8 remains stable, thus improving the stability of the entire device.

[0027] It is worth noting that the technical features such as the extrusion mechanism 2 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, control method and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0028] Working principle: First, when it is necessary to crack nuts of different sizes, the operator pulls the lever 76 to squeeze and move the extrusion shell 73. With the cooperation of the moving column 74 and the compression spring 75, the extrusion shell 73 is disengaged from the limiting hole 71, thereby adjusting the distance between the pressure plate 8 and the extrusion mechanism 2. Under this action, the device can crack nuts of different types and sizes, avoiding the complicated operation of frequent disassembly to crack nuts of different sizes, thus improving the cracking efficiency and adaptability of the entire device. Then, the nuts are cracked by the cooperation of the extrusion mechanism 2 and the pressure plate 8. After cracking, when it is necessary to collect the nuts on the surface of the pressure plate 8, the operator pulls the handle 11 to move the drawer 9. The movement allows the movable block 4 to detach from the protective shell 1 and simultaneously displace the rotating wheel 101. Under the action of the rotating wheel 101, the movable block 4 is able to squeeze the movable block 4 during the movement of the drawer 9. This causes the movable block 4 to rotate through the rotating shaft 3, allowing the broken nuts on its surface to slide into the drawer 9 for collection. This facilitates the centralized cleaning of the nuts for inspection by the inspectors, improving the convenience of cleaning the surface of the device and effectively reducing the impact of broken nuts on the surface of the pressure plate 8 on the subsequent shell-breaking effect. When the broken nuts are collected inside the drawer 9, the movable block 4 is reset and limited and supported by the tension spring 103 and the positioning plate 104, effectively improving the stability of the entire device.
