Description

Technical Field

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

[0002] Nuts have hard shells, so when eating nuts, they need to be opened with tools such as openers and hammers. However, existing openers are only suitable for a certain type of product, such as Hawaiian openers and nutcrackers, and are generally handheld, which is laborious. There are also safety hazards such as easy splashing of the shell when opening and easy pinching of the hand during operation.

[0003] Therefore, a nut opening device that is safer and simpler is needed to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a nut opening device in order to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A nut opening device comprises a base, a nut placement groove is formed on the base, a screw hole is formed on the base, a screw rod is threadedly connected to the screw hole, a fixing rod is fixedly connected to the screw rod, a connecting plate is rotatably connected to the fixing rod, the connecting plate contacts with a pressure plate, an opening is formed on the pressure plate and is slidably connected to the fixing rod, an opening knife is fixed on the pressure plate, and the connecting plate and the pressure plate are fixed by a connecting piece.

[0007] Preferably, the connecting member comprises a transverse hole formed on the connecting plate, the transverse hole is connected to a rotating rod via a thread, a round block is fixedly connected to the end of the rotating rod, and an arc groove which fits with the outer wall of the round block is formed on the pressure plate.

[0008] Preferably, a protrusion is fixedly connected to the connecting plate, and a round hole matching the protrusion is formed on the pressure plate.

[0009] Preferably, a notch communicating with the placement groove is provided on the base.

[0010] Preferably, an elastic rubber gasket protrudes from the portion of the bottom of the pressure plate that contacts the connecting plate.

[0011] Preferably, the side wall of the round block abuts against the inner wall of the arc-shaped groove, and at this time the round block does not contact the fixing rod.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. In the process of rotating the fixed rod, the pressure plate will move downward, and the opening knife will open the nut in the placement groove. Since the nut is restricted by the placement groove, the nut cannot escape from the placement groove during the opening process, so there will be no nut shell splashing. It is safer and more effective to use the device to open the nut.

[0014] 2. In the present application, the round block can be disengaged from the arc groove by rotating the rotating rod, thereby contacting the restriction on the pressure plate. Therefore, the operator can remove the pressure plate from the device and replace it with a pressure plate of other types of opening knives. The device has a wider range of uses and can be used for various types of nuts. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] The utility model provides a technical solution, please refer to Figure 1-3 :

[0023] A nut opening device comprises a base 1, a nut placement groove 2 is provided on the base 1, a notch 3 connected to the placement groove 2 is provided on the base 1, a screw hole 4 is provided on the base 1, a screw rod 16 is connected to the screw hole 4 by threading, a fixing rod 7 is fixedly connected to the screw rod 16, a connecting plate 5 is rotatably connected to the fixing rod 7, the connecting plate 5 contacts with a pressure plate 11, an opening 12 is provided on the pressure plate 11 for sliding connection with the fixing rod 7, an opening knife 15 is fixed on the pressure plate 11, and the connecting plate 5 and the pressure plate 11 are fixed by a connecting piece. After the connecting plate 5 and the pressure plate 11 are fixed by the connecting piece, the fixing rod 7 can rotate to make the screw rod 16 extend into the screw hole 4 during rotation, so that the opening knife 15 on the pressure plate 11 extends into the placement groove 2, and the nut in the placement groove 2 is opened, and the opening condition of the nut can be checked through the notch 3. An elastic rubber gasket protrudes from the bottom of the pressure plate 11 and the part in contact with the connecting plate 5. Therefore, no wear will occur when the pressure plate 11 contacts the connecting plate 5 .

[0024] Embodiment 2:

[0025] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the connecting member includes a transverse hole 6 provided on the connecting plate 5, the transverse hole 6 is connected to a rotating rod 8 by a thread, a round block 9 is fixedly connected to the end of the rotating rod 8, and an arc groove 14 is provided on the pressure plate 11 to fit the outer wall of the round block 9. The side wall of the round block 9 abuts against the inner wall of the arc groove 14, and the round block 9 does not contact the fixed rod 7 at this time. Therefore, the round block 9 can stably press and fix the pressure plate 11 and the connecting plate 5 without affecting the fixed rod 7. A protrusion 10 is fixedly connected to the connecting plate 5, and a round hole 13 adapted to the protrusion 10 is provided on the pressure plate 11. After the protrusion 10 extends into the round hole 13, the fixing of the connecting plate 5 and the pressure plate 11 can be made more stable, and the connecting plate 5 and the pressure plate 11 will not rotate relative to each other.

[0026] In summary, the present embodiment provides a method of sleeve the opening 12 of the pressure plate 11 on the fixing rod 7 until the pressure plate 11 contacts the connecting plate 5 and the protrusion 10 extends into the circular hole 13. The rotating rod 8 is rotated so that the round block 9 fits with the arc groove 14 on the pressure plate 11. The nuts are placed in each placement groove 2 in turn, and the screw rod 16 is connected to the screw hole 4 by a thread. The fixing rod 7 is rotated so that the screw rod 16 moves downward during rotation until the opening knife 15 on the pressure plate 11 opens the nut in the placement groove 2. Then, the fixing rod 7 is rotated in the opposite direction so that the opening knife 15 is disengaged from the placement groove 2, and the pressure plate 11 is rotated so that the opening knife 15 is rotated to align with the nut in the other placement groove 2. The fixing rod 7 is rotated so that the opening knife 15 moves downward with the pressure plate 11 to open the nut in the placement groove 2.

[0027] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
