Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a nut shelling device. Background Art

[0002] Nuts are a category of closed fruits. They have a hard peel and contain one or more seeds. Nuts are comprehensive and rich in nutrition. Regular consumption can prevent and treat heart disease, cancer, and vascular disease, and can also improve eyesight and brain health. Nuts include the outer shell and the inner seeds. The shell is hard and difficult to peel. Nuts are loved by more and more people because of their nutritional value. Nuts are usually made into dried fruits and sold. In order to facilitate eating, the hard peel needs to be removed in advance, and then the inner kernel needs to be taken out for packaging. At present, some small and medium-sized enterprises or small workshops do not have matching nut kernel extraction equipment. Nut shelling and kernel extraction need to be done manually, which will increase the processing cost of nuts and have low economic benefits. Some existing shelling equipment often shells multiple nuts at the same time. Although it can improve efficiency, due to the different sizes of each nut, if you want to shell them at the same time, you need to shell the nuts according to their size each time, otherwise the smaller nuts will not be able to complete the shelling. In this way, the process is increased, resulting in an increase in the overall time of the shelling process, which reduces the overall efficiency of nut processing. Utility Model Content

[0041] Example

[0042] Combination Figure 1-Figure 4In the present embodiment, a nut shelling device is provided to address the problem that smaller nuts cannot be shelled smoothly when shelling with the existing nut shelling devices. A corresponding push knife mechanism 10 is provided on the side of each processing groove 73, and each push knife mechanism 10 is driven by a corresponding push knife driving mechanism 11, that is, each shelling knife 104 used for shelling nuts is controlled by a push knife driving mechanism 11, and each push knife mechanism 10 is provided with a pressure sensor. When shelling, the push knife driving mechanism 11 first pushes the shelling knife 104 close to the nut. After the pressure sensor senses that the shelling knife 104 cooperates with the buffer mechanism 6 to clamp the nut, the unloading mechanism 7 flips downward and no longer supports the nut, thereby ensuring that each shelling knife 104 is close to the nut, and then the shelling knife 104 quickly advances to complete the shelling, thereby achieving the simultaneous shelling of nuts of different sizes, without the need to screen nuts of the same size for shelling in advance, thereby saving processes and improving the efficiency of nut processing. Specifically,

[0043] A nut shelling device of the present embodiment includes a frame 100, which is a square frame and includes two oppositely arranged side panels 110, and the side panels 110 are connected by a bottom plate and a cross beam 120. In the present embodiment, the bottom plate and the cross beam 120 are spaced apart, and an opening 130 is formed between the bottom plate and the cross beam 120, and a conveyor belt is arranged below the opening 130. After the nuts are shelled, they fall onto the conveyor belt through the opening 130, and the nuts are conveyed away by the conveyor belt.

[0044] In this embodiment, a feeding mechanism 7 is arranged on the frame 100, and the feeding mechanism 7 is rotatably arranged on the frame 100. In this embodiment, the feeding mechanism 7 is arranged above the opening 130, and the feeding mechanism 7 reciprocates on the frame 100. When the feeding mechanism 7 is rotated downward to open, the nuts can fall; when the feeding mechanism 7 is rotated upward to close, the nuts can fall on the feeding mechanism 7. The feeding mechanism 7 includes a feeding shaft 71, a flip plate 72, and a processing groove 73. The flip plate 72 is installed on the frame 100 through the feeding shaft 71, and the flip plate 72 rotates along the feeding shaft 71.

In order to prevent the nut from being too large and its diameter exceeding the processing groove 73, thereby causing two adjacent nuts to collide, in this embodiment, the processing grooves 73 are arranged at intervals, and the intervals are larger than the width of one processing groove 73. In this embodiment, the unloading mechanism 7 is driven by the unloading driving mechanism 2 to flip. The unloading driving mechanism 2 includes a mounting plate 21, which is fixed on the frame 100, and a rotating wheel 22 is installed on the mounting plate 21.

When the rotating wheel 22 rotates, it drives one end of the transmission rod 23 to make a circular motion, and the other end drives the movable end of the rotating rod 24 to make an arc motion, thereby driving the unloading rotating shaft 71 to rotate back and forth, thereby realizing the opening and closing of the flip plate 72.

In this embodiment, when cracking the nut shell, the shelling knife 104 is close to the nut, and the pressure is applied to the propulsion spring 103, and the pressure is transmitted to the pressure sensor. A threshold value is set for the pressure sensor. When the pressure felt by the pressure sensor exceeds the threshold value, it is determined that the nut is clamped.
