[0002] Walnut is a nut that is rich in nutrients. The walnut has a hard shell and a brain-shaped kernel. It is rich in fat, protein, carbohydrates, as well as calcium, phosphorus, iron, zinc, vitamin E and other nutrients. In daily life, walnuts can be eaten directly, or used as cooking ingredients to make cakes, candies or added to porridge to increase the nutritional value of food. Walnuts are often shelled using shelling equipment.

[0003] Most of the existing shelling equipment has a fixed roller spacing. When shelling walnuts of different sizes, manual screening is required, and then the rollers need to be adjusted according to the size of the walnuts, which is time-consuming and labor-intensive, reducing work efficiency. In addition, during the shelling process, it is usually difficult to avoid the generation of a large amount of walnut shell fragments and dust, and most equipment does not have an effective shell debris removal mechanism, resulting in a lot of shell debris on the surface of the walnut kernel, affecting subsequent processing.

[0004] Therefore, the utility model provides a walnut shelling device that is easy to clean for processing, so as to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0034] A mounting plate 602 is fixed on the upper end of the device body 1, and a plurality of through holes 601 are arranged inside the mounting plate 602 for orderly introduction of walnuts. A rotating motor 607 is firmly mounted on one side inside the device body 1, and its output end is connected to an auger 606. One end of the auger 606 is fixed, and the other end can rotate flexibly inside the device body 1, so that the walnuts are evenly pushed into the shelling link. One of the two transmission wheels 611 is directly fixed on the output end of the rotating motor 607, and the two are tightly meshed through a conveyor belt 608 to ensure power transmission. The other transmission wheel 611 is fixed on one side of the two pressure rollers 604, and the two pressure rollers 604 can rotate freely inside the device body 1. A plurality of annular grooves 603 are designed on the outer circumference for precise extrusion and shelling of walnuts.

[0036] During the walnut shelling operation stage, when the first gear 609 rotates, its linkage force will be transmitted to the second gear 610 meshing with it, so that the rotating block 605 connected to the second gear 610 performs regular up and down vibration, so that the walnut shell fragments and the walnut kernels will enter the storage box 702 inside the equipment together, and pass through the first filter screen 701 inside the collection box 704. The first filter screen 701 is fixed inside the collection box 704, effectively blocking most of the walnut shell fragments, ensuring that the walnut kernels can be retained relatively pure. Subsequently, the driving motor 705 is activated to drive the linkage mechanism 706 to operate. The linkage mechanism 706 is composed of a chain, multiple sprockets, a chain tensioner and a chain guide. The chain transmits power from one sprocket to the other through meshing with the sprocket. Another sprocket drives multiple brushes 703 to rotate, the chain tensioner adjusts and maintains the appropriate tension of the chain to prevent the chain from slipping and derailing due to relaxation during operation, ensuring that the chain and the sprocket always maintain a good meshing state, the chain guide limits and guides the running trajectory of the chain to prevent the chain from deviating from the predetermined path during transmission, and at the same time can reduce the lateral swing of the chain, reduce the abnormal wear of the chain and the sprocket, and extend the service life of the chain, thereby ensuring the stability and efficiency of the linkage mechanism 706, and realizing the fine removal of shell chips adhered to the periphery of the walnut kernel, which can not only ensure that the walnut kernel is not contaminated by shell chips and maintain its purity and quality, but also effectively collect shell chips, avoiding environmental pollution and waste of resources caused by the flying of shell chips.

[0037] A protective door 2 is hingedly provided at the front end of the device body 1. The hinged protective door 2 provides a safety barrier for the operator to prevent accidents from causing harm to the human body during the operation of the equipment. It is also convenient to open it for inspection and repair during equipment maintenance and cleaning. A control panel 4 is fixedly provided on one side of the device body 1. The control panel 4 facilitates the staff to monitor and adjust the working parameters of the equipment in real time to achieve precise control and automated operation. Four supporting legs 5 are fixedly provided at the lower end of the device body 1. The supporting legs 5 can ensure that the entire device is firmly placed on the ground to avoid instability caused by vibrations generated during the operation of the equipment. A feed port 3 is fixedly provided at the upper end of the device body 1. The feed port 3 is the entrance of the walnut raw material, which is convenient for the walnuts to be continuously fed into the equipment for processing. A bellows 8 is fixedly provided at the lower end of the storage box 702, and an exhaust fan 9 is fixedly provided at the input end of the bellows 8. When the exhaust fan 9 is started, a negative pressure will be formed in the bellows 8, generating a strong airflow, thereby extracting and collecting broken shells and other impurities in the process of walnut shelling, and guiding them into the equipment through the airflow, thereby realizing effective cleaning and environmentally friendly production inside the equipment, reducing the difficulty of subsequent cleaning work, and improving the overall work efficiency and environmental sanitation level.

[0038] Working principle: When processing walnuts, the walnuts are put into the device body 1 through the feed port 3, and the rotating motor 607 is started to drive the internal auger 606 to start rotating, so that the walnuts are smoothly transported to the pressure roller 604 through the through holes 601 of different sizes in the mounting plate 602, and just fall into the corresponding annular groove 603. With the operation of the rotating motor 607, the transmission wheel 611 and the conveyor belt 608 rotate, and are transmitted to the two pressure rollers 604 through the meshing first gear 609, so that they rotate, thereby completing the shelling operation of the walnuts. When the first gear 609 rotates, it acts on the meshing second gear 610, so that the walnuts connected to the second gear 610 are The rotating block 605 then performs a reciprocating up and down vibration motion. After the walnut is completely shelled, the walnut kernel and the shell debris produced fall into the collection box 704 inside the storage box 702 at the lower part of the device body 1. At this time, the first filter 701 inside the collection box 704 begins to play a screening role, allowing smaller shell debris to pass through while retaining the walnut kernel. The linkage mechanism 706 is driven by the starting motor to drive the brush 703 to rotate. The shell debris attached to the surface of the walnut kernel is effectively removed by physical brushing. The exhaust fan 9 is started to generate negative pressure suction through the bellows 8 to extract the shell debris and other impurities that have been screened out by the filter, ensuring that the walnut kernel reaches a higher cleanliness standard.
