Description

Technical Field

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

[0002] Nuts include walnuts, macadamia nuts, etc. Since the shells of nuts are hard, it is generally necessary to use tools to break the shells to get the kernels inside the shells.

[0003] Currently available nut shelling tools on the market include shelling pliers, rotary squeezers, etc.

[0004] When the shell cracking pliers are clamping nuts, the first hand needs to hold the nut and align it with the upper and lower clamping points of the chuck, and then the second hand presses the pliers handle to clamp the nut before the first hand can be withdrawn. That is, the shell cracking pliers need two hands to operate when initially positioning the nut.

[0005] At the same time, shell cracking pliers require a relatively large squeezing force when cracking nut shells, which makes it difficult for girls and children to use. When boys use them, it is difficult to control the squeezing force, and they often tend to crush the shell and the kernel inside the shell together, affecting the taste of the kernel.

[0006] When using the rotary squeezer, the nut is placed into a gap, and then the screw is rotated so that the end face of the screw and the bottom wall of the gap move relative to each other to break the nut shell. However, both sides of the gap are open, so the initial positioning of the nut still requires the first hand to hold the nut and align it with the upper and lower clamping points between the screw and the bottom wall of the gap, and then the second hand rotates the screw down to clamp the nut before the first hand can be withdrawn. The positioning operation is still inconvenient. At the same time, the rotary squeezer still requires a lot of strength to squeeze the nuts by rotating the screw, which is still laborious for girls and children to use, and the user experience is not good. At the same time, the shelling process usually crushes the kernels of the nuts.

[0007] That is, the existing nut shelling tools are inconvenient to use, and the positioning operation is troublesome and laborious.

[0008] Therefore, the prior art needs to be improved. Utility Model Content

[0009] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an easy-to-use nut sheller, which aims to facilitate positioning and save labor when shelling nuts, maintain the integrity of the kernels, and enhance the user experience.

[0010] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] A nut sheller that is easy to use, comprising:

[0012] A housing seat, wherein a shell breaking groove is provided in the housing seat, a nut input opening is provided on one side of the shell breaking groove, a side contact portion for blocking the side of the nut is provided on the other side of the shell breaking groove, and a lower contact portion for abutting against the bottom of the nut is provided at the bottom of the shell breaking groove;

[0013] A spiral extrusion piece, the spiral extrusion piece comprises a screw rod spirally connected to the accommodation seat, one end of the screw rod is provided with an upper contact portion and extends into the shell breaking groove, the upper contact portion is used to abut against the top of the nut;

[0014] One of the upper contact part and the lower contact part is an anti-slip tip, and the other is a shell-breaking knife with a blade, and the screw rod moves up and down in the shell-breaking groove so that the anti-slip tip and the shell-breaking knife move toward or in the opposite direction;

[0015] When the anti-skid tip and the shelling knife move toward each other to squeeze the nuts, the anti-skid tip can be embedded in the shell of the nuts.

[0016] In some examples, when the anti-slip tip and the shelling knife move toward each other to squeeze the nut, the anti-slip tip first contacts the nut shell and then embeds into the nut shell to form an initial positioning shelling hole.

[0017] In some examples, the shell breaking groove can be thrown into the nut in a vertical, inclined, or horizontal state and can be abutted by at least the lower contact portion and the side contact portion to position the nut.

[0018] In some examples, when the distance between the upper contact portion and the lower contact portion is adjusted to a suitable distance, a nut thrown in can be simultaneously abutted and positioned by the upper contact portion, the lower contact portion, and the side contact portion.

[0019] In some examples, the height of the anti-slip tip and the blade are approximately equal to the thickness of the nut shell.

[0020] In some examples, when the screw moves to the lowermost end in the shell breaking groove, a finger protection gap is formed between the upper contact portion and the lower contact portion.

[0021] In some examples, a guiding structure that can automatically guide the nut is provided on the abutting surface between the side contact portion and the nut.

[0022] In some examples, the side contact portion is a surrounding plate, and the guide structure is an arc surface or two inclined surfaces at an angle provided on the inner wall of the surrounding plate.

[0023] In some examples, the vertical protrusions on the two arc surfaces or inclined surfaces are provided with at least two positioning legs.

[0024] In some examples, a tool guard is further provided on the accommodating seat, and the tool guard shields a side of the shelling knife adjacent to the nut input opening.

[0025] It should be understood that within the scope of the present invention, the above-mentioned technical features of the present invention and the technical features specifically described below (such as implementation methods) can be combined with each other to form new or preferred technical solutions. Due to space limitations, they will not be described one by one here.

[0026] The beneficial effects of the utility model are as follows: by providing a receiving seat with a shell-breaking groove and a spiral extrusion member with a screw, the end of the screw is provided with an upper contact portion, the bottom and side of the shell-breaking groove are provided with a lower contact portion and a side contact portion, one of the upper contact portion and the lower contact portion is an anti-slip tip, and the other is a shell-breaking knife with a raised blade. When positioning the nut, the shell-breaking groove is slightly tilted toward the side contact portion or not tilted, and then the nut is put into the shell-breaking groove, the side of the nut naturally abuts against the side contact portion, and the bottom of the nut naturally abuts against the anti-slip tip or the blade of the shell-breaking knife to automatically complete the preliminary positioning. The nut sheller of the utility model does not need to hold the nut in the shell-breaking groove with one hand to align the anti-slip tip and the shell-breaking knife during the positioning operation before the nut is clamped, and there is no need to wait for the rotating screw to make the anti-slip tip and the shell-breaking knife clamp the nut before releasing the hand holding the nut. The utility model only needs to use one hand to put the nut into the shell-breaking groove and then withdraw the hand, and the nut can be automatically positioned by putting the nut into the nut sheller, and the positioning operation is very simple and convenient.

[0027] At the same time, since the utility model adopts the anti-skid tip and the shelling knife, the blade of the shelling knife itself has the shelling function, and the anti-skid tip can be quickly embedded in the shell of the nut, which also plays a role of fast fixing and auxiliary shelling, and the anti-skid tip can be embedded in the shell under a very small thrust to destroy the shell, and combined with the shelling effect of the shelling knife, the whole shelling process is much more labor-saving than pure squeezing to break the shell, so that girls and children can also easily break the shell of nuts, which improves the use experience. Again, the minimum distance between the anti-skid tip and the shelling knife forms a finger protection gap to prevent children's fingers from being pinched. At the same time, the anti-skid tip and the shelling knife are set with a reasonable effective height (i.e., approximately equal to the thickness of the shell) to ensure that the kernel is not damaged during the shelling process and ensure the integrity of the kernel after shelling.

[0051] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0052] The utility model includes the following embodiments.

[0053] Example 1, please refer to Figures 1 to 8 The present embodiment provides a nut sheller 100a that is easy to use, including a accommodating seat 1, a shell breaking groove 11 is arranged in the accommodating seat 1, a nut input opening 12 is arranged on one side of the shell breaking groove 11, a side contact portion 5 for blocking the side of the nut 200 is arranged on the other side of the shell breaking groove 11, and a lower contact portion 4 for abutting against the bottom of the nut 200 is arranged at the bottom of the shell breaking groove 11.

[0054] Specifically, the receiving seat 1 of this embodiment includes a bracket 13 and a base 14 arranged at the bottom of the bracket 13, and the shell breaking groove 11 is arranged in the bracket 13. The base 14 is used to hold or fix the entire shell breaker 100a by hand or in other ways, and the bracket 13 is used to open the shell breaking groove 11, and the bracket 13 is used to connect and support the spiral extrusion member 2. The bracket 13 and the base 14 can be separate structures or integrally formed structures. Figure 5 As shown, the bracket 13 and the base 14 of the first embodiment are separate structures, and the bracket 13 is mounted on the base 14 and then connected and fixed by connecting screws 10 or other methods. The bracket 13 and the base 14 can be made of the same material or different materials, such as the bracket 13 can be made of aluminum alloy and the base 14 can be made of plastic.

[0055] like Figure 1 and Figure 3 As shown, the bracket 13 of the first embodiment is provided with a shell breaking groove 11 in the front-to-back direction, and the front side of the shell breaking groove 11 is a nut input opening 12 for placing, inputting or throwing in nuts 200. The rear side of the shell breaking groove 11 is provided with a side contact portion 5, and the side contact portion 5 is used to cover the rear side of the shell breaking groove 11, so that the shell breaking groove 11 is a half-open groove (i.e., the front side is open), so that after the nut 200 is put into the shell breaking groove 11, the rear side of the nut 200 is blocked by the side contact portion 5, so that the nut will not fall out from the rear side of the shell breaking groove 11.

[0056] The side contact portion 5 can be arranged on the bracket 13 or on the base 14. In the first embodiment, the side contact portion 5 is arranged on the side of the base 14. When the bracket 13 is installed on the rear of the base 14, the side contact portion 5 just covers the rear side of the shell breaking groove 11.

[0057] Preferably, if Figure 4As shown, a guiding structure 50 is provided on the contact surface between the side contact portion 5 and the nut 200, which can automatically guide the nut 200. The guiding structure 50 can guide nuts 200 of different sizes placed in the shell breaking groove 11 to the center position of the shell breaking groove 11, preventing the nuts 200 from rolling in the shell breaking groove 11 during the initial positioning, so as to facilitate the subsequent clamping, fixing and shell breaking. The guiding structure 50 of this embodiment can guide and center nuts 200 of different sizes within a certain range.

[0058] Specifically, the side contact portion 5 is a surrounding plate 51 .

[0059] As a way, Figure 5 As shown, the guiding structure 50 is two angled inclined surfaces 502 arranged on the inner wall of the enclosure 51. The contact and guiding positions of the two inclined surfaces 502 and the nut 200 are respectively the centering contact points 513, and a groove 512 is formed between the two centering contact points 513, so that when the side of the nut 200 abuts against one of the inclined surfaces 502 of the enclosure 51, the nut 200 will roll toward the middle groove 512 under the restraining effect of the two inclined surfaces 502 until the centering contact points 513 on the two inclined surfaces 502 abut and clamp the nut 200, so that the center 0 of the nut 200 is located on the center line of the groove 512, which plays a centering role. Moreover, for nuts 200 of different sizes, the positions of the two centering contact points 513 with the inclined surface 502 will change due to the size of the nut 200, so as to meet the guiding and centering of nuts 200 of different sizes.

[0060] exist Figure 5 In the embodiment shown, the enclosure 51 itself is also configured to be V-shaped, so that two inclined surfaces 502 at an included angle are directly formed on the inner wall of the enclosure 51 to form the guiding structure 50. It is understood that in other embodiments, the enclosure 51 can also be other shapes to guide and center the nut 200.

[0061] Furthermore, if Figure 6 As shown, after the enclosure 51 abuts against the nut 200, the center 202 of the nut 200 is located on the center line b between the upper contact portion 3 and the lower contact portion 4. This can prevent the left and right centers of the nut 200 from shifting after the nut 200 is placed in the shell breaking groove 11, which is not conducive to positioning and squeezing the shell.

[0062] As another way, Figure 7As shown, the guiding structure 50 is an arc surface 501 provided on the inner wall of the enclosure 51. After the arc surface 501 contacts the side wall of the nut 200, two centering contact points 513 are also formed, and a groove 512 is formed between the two centering contact points 513. After the nut 200 contacts the arc surface 501, it rolls toward the middle groove 512 under the restraint of the arc surface 501, thereby playing a centering role. The arc surface 501 can also be used for centering and guiding nuts 200 of different sizes.

[0063] Furthermore, at least two positioning legs 511 are provided on the arc surface 501 or the two inclined surfaces 502 of the enclosure plate 51 as vertical protrusions. Figure 1 , Figure 7 As shown, two positioning legs 511 are provided on the inner protrusion of the arc surface 501 and are arranged along the vertical direction.

[0064] Two vertical positioning legs 511 protrude from the inner wall of the arc surface 501 of the enclosure 51 and are spaced apart on the inner wall, so that it is easier to form a groove 512 between the two positioning legs 511 on the inner wall, so that the two positioning legs 511 can not only clamp the sides of the nut 200, but also guide the nut 200 to the center, further preventing the nut 200 from shaking left and right in the shell breaking groove 11. The groove 512 is located at the center of the two positioning legs 511, so that after the nut 200 is positioned by the two positioning legs 511, the center of the nut 200 will not deviate left and right.

[0065] Preferably, if Figure 1 and Figure 7 As shown in the figure, the two positioning legs 511 of this embodiment are tilted in the vertical direction, so that the centering positioning of nuts 200 of different sizes can be adapted. Preferably, the upper spacing between the two positioning legs 511 is large, and the lower spacing is small. A large nut 200 is clamped by the upper portion of the two tilted positioning legs 51 to center the nut 200; while a small nut 200 is clamped by the lower portion of the two tilted positioning legs 51 to center the nut 200.

[0066] In the first embodiment, the enclosure 51 blocks the lower part of the side of the shell breaking groove 11, that is, the enclosure 51 of the first embodiment does not completely block the side of the shell breaking groove 11, but only blocks the lower part of the side of the shell breaking groove 11, which can save materials.

[0067] Please continue to refer to Figure 2 Since the bottom of the shell breaking groove 11 is provided with a lower contact portion 4, after the nut 200 is put into the shell breaking groove 11 from the nut input opening 12, the bottom of the nut 200 abuts against the lower contact portion 4, and the rear side of the nut 200 abuts against the two positioning shanks 511 of the side contact portion 5. In this way, the shell breaker 100 automatically positions the abutted nut 200 from the bottom and the side.

[0068] The nut shelling device 100a of the present embodiment further comprises a spiral extrusion member 2, wherein the spiral extrusion member 2 comprises a screw rod 21 spirally connected to the receiving seat 1, and an upper contact portion 3 is provided at one end of the screw rod 21 and extends into the shelling groove 11. Figure 2 As shown, the upper contact portion 3 is used to abut against the top of the nut 200 .

[0069] Specifically, the spiral extrusion member 2 of this embodiment further includes a handle 22, which is connected to the end of the screw rod 21 away from the upper contact portion 3, and the handle 22 is used to rotate the screw rod 21 so that the screw rod 21 rises or falls in the shell breaking groove 11. The handle 22 and the screw rod 21 are an integrated structure or a separate structure.

[0070] like Figure 7 As shown, in the first embodiment, a screw hole 131 is formed on the top of the bracket 13, and the screw rod 21 is screwedly connected to the screw hole 131. The screw rod 21 rotates in the screw hole 131 so that the screw rod 21 as a whole rises or falls, thereby driving the upper contact portion 3 at the lower end of the screw rod 21 to move up and down in the shell breaking groove 11.

[0071] One of the upper contact part 3 and the lower contact part 4 of the utility model is an anti-slip top 31, and the other is a shelling knife 41 with a blade 411, that is, when the upper contact part 3 of the nut sheller of the utility model is the anti-slip top 31, the lower contact part 4 is the shelling knife 41; or when the upper contact part 3 of the nut sheller of the utility model is the shelling knife 41, the lower contact part 4 is the anti-slip top 31.

[0072] like Figure 1 and Figure 8 As shown, in the first embodiment, the upper contact portion 3 is an anti-skid tip 31, and the lower contact portion 4 is a shelling knife 41. The shelling knife 41 has a raised blade 411, and the blade 411 is in line contact with the bottom of the nut 200, while the anti-skid tip 31 can be in point contact with the top of the nut 200. The tip of the anti-skid tip 31 is a conical tip so as to have sufficient strength and be able to penetrate into the shell of the nut 200.

[0073] The screw rod 21 of the utility model moves up and down in the shell breaking groove 11 so that the anti-skid tip 31 and the shell breaking knife 41 move toward or in the opposite direction. As in the first embodiment, when the screw rod 21 is rotated by the handle 22 so that the screw rod 21 moves downward in the shell breaking groove 11, the anti-skid tip 31 moves downward relative to the shell breaking knife 41, so that the nut 200 placed in the shell breaking groove 11 can be squeezed and shelled. When the screw rod 21 is rotated by the handle 22 so that the screw rod 21 moves upward in the shell breaking groove 11, the anti-skid tip 31 moves upward relative to the shell breaking knife 41 in the opposite direction, so that the nut 200 can be loosened or a larger distance is created between the anti-skid tip 31 and the shell breaking knife 41 to facilitate the placement of the nut 200.

[0074] In the process of the anti-skid tip 31 and the shelling knife 41 moving toward each other to squeeze the nut 200, the anti-skid tip 31 can be embedded in the shell of the nut 200. Because the anti-skid tip 31 can be embedded in the shell of the nut 200, during the process of shelling the nut 200, the anti-skid tip 31 can not only position the nut 200, quickly fix the nut 200, but also assist in shelling the nut 200.

[0075] In the process of cracking the nut 200, the nut 200 needs to be positioned first so as to clamp the nut 200, and then the nut 200 is squeezed to crack the shell.

[0076] The nut sheller of the utility model is simple and convenient to position the nut 200. There is no need to hold the nut 200 in the shelling groove 11 with one hand and align the anti-slip top 31 and the shelling knife 41 up and down and keep it still. The positioning process of the nut sheller of the utility model is as follows:

[0077] 1. First, the screw rod 21 is rotated upward, so that the screw rod 21 rises in the shell breaking groove 11 so that there is enough space between the anti-slip top 31 and the shell breaking knife 41 to be able to put the nut 200 into the shell breaking groove 11.

[0078] 2. Tilt the accommodating seat 1 slightly backward or place it vertically without tilting, and then put or drop the nut 200 into the shell breaking groove 11. The side wall of the nut 200 is abutted by the side contact part 5, and the bottom of the nut 200 is abutted by the lower contact part 4. The lower contact part 4 is the line contact between the blade 411 of the shell breaking knife 41 and the bottom of the nut 200 or the point contact between the anti-slip top 31 and the bottom of the nut 200. In this way, the nut 200 placed or dropped into the shell breaking groove 11 will not roll and will be automatically positioned by the side contact part 5 and the lower contact part 4. Then, slightly turn down the screw 21 so that the upper contact part 3 slightly abuts the top of the nut 200.

[0079] When the nut sheller of the present invention positions the nut 200, the hand holding the nut 200 can be withdrawn after the nut 200 is placed or dropped into the shell breaking groove 11, and there is no need to hold the nut 200 in the shell breaking groove 11 and continuously align the anti-slip top 31 and the shell breaking knife 41 up and down until the upper contact part 3 presses the top of the nut 200 and cannot be withdrawn. Therefore, the nut sheller of the present invention is convenient and simple to position the nut 200.

[0080] The process of squeezing and shelling nuts 200 by the nut shelling device of the utility model is as follows:

[0081] 1. After the nut 200 is positioned in the shell breaking groove 11, the downwardly rotating screw 21 causes the anti-slip top 31 and the shell breaking knife 41 to move relative to each other to squeeze the nut 200.

[0082] 2. During the extrusion process, the anti-slip tip 31, the shelling knife 41, and the side contact portion 5 are positioned and fixed at at least four contact points in the upper, lower, and side directions of the nut 200, which has a good positioning and fixing effect and prevents the extrusion force from causing the nut 200 to move in the shelling groove 11.

[0083] 3. During the squeezing process, the anti-skid tip 31 can penetrate into the shell of the nut 200 with only a small force, and the penetration of the anti-skid tip 31 into the shell has a piercing and crushing effect on the shell. At the same time, under the action of the squeezing force, the shell breaking knife 41 will also be embedded in the shell and have an embedding and crushing effect on the shell. In this way, under the dual shell breaking action of the anti-skid tip 31 and the shell breaking knife 41, the shell is quickly broken without the need to continue to apply squeezing force.

[0084] Due to the double shelling effect of the anti-slip tip 31 and the shelling knife 41, the nut shelling device of the utility model can achieve shelling by applying a small squeezing force to the nut 200, compared with the prior art that relies on simple squeezing and crushing. The nut shelling device of the utility model can achieve shelling by applying a small squeezing force to the nut 200, which is labor-saving. Girls and children can also easily shell the nuts, which greatly improves the user experience and is not easy to crush the kernel. At the same time, the nut shelling device of the utility model has a simple structure and is easy to carry and store. The nut shelling device of the utility model is particularly suitable for shelling macadamia nuts.

[0085] Preferably, if Figure 1 As shown, the center of the anti-slip tip 31 of this embodiment is aligned with the center of the shell breaking knife 41. When in a vertical state, the center of the anti-slip tip 31 and the center of the shell breaking knife 41 are located on the same vertical axis a, so that the extrusion force will not be offset and it is conducive to rapid shell breaking.

[0086] like Figure 2 and Fig. 9 As shown, in the process where the anti-skid tip 31 and the shelling knife 41 of this embodiment move toward each other to squeeze the nut 200, the anti-skid tip 31 first makes point contact with the shell of the nut 200 and then embeds into the shell to form an initial positioning shelling hole 201. That is, during the extrusion and shelling process, the anti-skid tip 31 first makes point contact with the nut 200, and then during the continued force application, the anti-skid tip 31 will embed into the shell to form an initial positioning shelling hole 201 on the shell of the nut 200. The initial positioning shelling hole 201 is equivalent to first forming a positioning point and a rupture point on the surface of the nut 200. It is common sense that after the rupture point is first formed on the surface of the material, the material is easier to break, which is more labor-saving than directly breaking a material without a rupture point. Fig. 9As shown in the figure, after the initial positioning shell-breaking hole 201 is formed on the top of the nut 200, a slight downward squeezing force is applied, and in combination with the action of the shell-breaking knife 41, the surface of the nut 200 will extend from the initial positioning shell-breaking hole 201 to form multiple cracks around it, so that the shell can be broken quickly. That is, the design of the anti-slip top 31 of this embodiment plays an important role in the initial destruction of the shell-breaking process of the nut 200, thereby achieving labor-saving and rapid shell-breaking.

[0087] Generally, in the shelling process of this embodiment, the anti-slip tip 31 will first be embedded in the shell of the nut 200 to form an initial positioning shelling hole 201, and then the shelling knife 41 will be embedded in the shell of the nut 200, so as to reduce the squeezing force required for shelling.

[0088] Preferably, if Figure 2 , Fig.10 and Fig.11 As shown, the shell breaking groove 11 of this embodiment can be thrown into the nut 200 in the vertical, inclined, or horizontal state and at least the lower contact portion 4 and the side contact portion 5 can abut and position the nut 200. Because of the blocking effect of the side contact portion 5, no matter the accommodating seat 1 (i.e., the shell breaking groove 11) is in the vertical, inclined, or horizontal state, the nut 200 thrown into the shell breaking groove 11 from the nut input opening 12 will be blocked by the side contact portion 5 and will not fall out from the other side of the shell breaking groove 11. The side of the thrown nut 200 contacts and aligns with at least two positioning shanks 511 on the side contact portion 5, and the bottom will also abut against the lower contact portion 4 to achieve preliminary abutment positioning.

[0089] That is, the nut sheller of the present embodiment can realize the throwing and positioning of nuts. The hand holding the nuts does not need to be inserted into the shell breaking groove 11, but the nut 200 can be directly thrown into the shell breaking groove 11 at a position at a certain distance from the shell breaking groove 11. This throwing and positioning method cannot be achieved in the prior art.

[0090] Furthermore, in this embodiment, when the distance between the upper contact portion 3 and the lower contact portion 4 is adjusted to a suitable distance, the thrown nut 200 can be simultaneously abutted and positioned by the upper contact portion 3, the lower contact portion 4, and the side contact portion 5. For example, if the suitable distance between the upper contact portion 3 and the lower contact portion 4 is slightly larger than the diameter of the shell of the nut 200, after the nut 200 is thrown into the shell breaking groove 11 from a long distance, the anti-slip tip 31, the shell breaking knife 41, and the two positioning shanks 511 on the side contact portion 5, a total of at least four points, can firmly clamp and position the nut 200, and the positioning effect is better.

[0091] like Fig.12 As shown, the height of the anti-skid tip 31 and the blade 411 of this embodiment is approximately equal to the thickness of the shell of the nut 200. Fig.12As shown in the figure, the height c of the anti-skid tip 31 of this embodiment and the height d from the bottom to the top of the blade 411 are both approximately equal to the thickness of the shell of the nut 200. That is, the anti-skid tip 31 and the blade 411 of this embodiment are both set with an effective shell breaking height, so that when the anti-skid tip 31 and the blade 411 are completely embedded in the shell during the shell breaking process of the nut 200 by the downwardly rotating screw 21, the shell breaking of the nut 200 is completed, and at this time, the state of the anti-skid tip 31 and the blade 411 just destroys the shell of the nut 200, thereby avoiding damage to the kernel, and can effectively protect the integrity of the kernel of the nut 200, thereby ensuring the edible taste of the kernel of the nut. In the specific shell breaking operation of this embodiment, after the anti-skid tip 31 and the blade 411 of the downwardly rotating screw 21 break the shell of the nut 200, the screw 21 is no longer rotated downward, that is, the nut 200 is no longer squeezed after the shell of the nut 200 is broken during the shell breaking process, so as to ensure the integrity of the kernel.

[0092] Furthermore, if Fig.13 As shown, when the screw rod 21 of the present embodiment moves to the lowest end in the shell breaking groove 11, a finger protection gap 7 is formed between the upper contact portion 3 and the lower contact portion 4. That is, during the shell breaking process, when the screw rod 21 is rotated downward and moved to the lowest end, the distance between the upper contact portion 3 and the lower contact portion 4 reaches a minimum value, that is, the distance between the anti-slip tip 31 and the shell breaking knife 41 reaches a minimum value, and the minimum value at this time is the finger protection gap 7, which is greater than the height of a finger of a child or an adult. For example, the distance of the finger protection gap 7 is generally set to be greater than 10 mm or greater than 12 mm.

[0093] The finger protection gap 7 is used to prevent children or adults from getting their fingers pinched. In this way, when a child or an adult accidentally puts a finger into the shell breaking groove 11, even if the screw rod 21 is screwed down to the bottom, the finger will not be squeezed and injured because of the existence of the finger protection gap 7.

[0094] Preferably, if Figure 1 and Figure 7 As shown, a tool guard 6 is also provided on the accommodating seat 1, and the tool guard 6 blocks the side of the shelling knife 4 adjacent to the nut input opening 12. The tool guard 6 is used to block the side of the shelling knife 4 to prevent scratching the operator's fingers. In this embodiment, the tool guard 6 is arranged on the side of the base 14.

[0095] Preferably, if Figure 3 and Figure 7 As shown, a chip discharge port 8 is also provided at the lower portion of the enclosure plate 51, and the chip discharge port 8 is convenient for discharging the broken shell chips inside the shell breaking groove 11 to prevent the shell chips from accumulating.

[0096] Specifically, Figure 7As shown, the bracket 13 of this embodiment is provided with a T-shaped card slot 132 at the bottom of the shell breaking groove 11, and the shell breaking knife 41 is provided with a T-shaped card strip 412. After the T-shaped card strip 412 is slidably inserted into the T-shaped card slot 132, the shell breaking knife 41 is clamped on the bracket 13. The sliding cooperation between the T-shaped card slot 132 and the T-shaped card strip 412 facilitates the installation and removal of the shell breaking knife 41, and the clamping cooperation between the T-shaped card slot 132 and the T-shaped card strip 412 can firmly install the shell breaking knife 41 on the bracket 13. It can be understood that in other embodiments, the shell breaking knife 41 can also be installed and fixed on the bracket 13 in other ways.

[0097] Preferably, the cross-sectional shape of the blade 411 of the shell-breaking knife 41 of this embodiment is triangular. The blade 411 of the triangular cross-sectional shape is high in strength and not easily damaged. It can be understood that in other embodiments, the cross-sectional shape of the blade 411 of the shell-breaking knife 41 can also be other shapes.

[0098] Example 2, please refer to Fig.14 and Fig.15 This embodiment provides a nut shelling device 100b that is easy to use. The difference between the embodiment 1 and the embodiment 1 is that the enclosure 51 of the embodiment 2 covers the entire side of the shelling groove 11. This makes the strength of the entire shelling device 200 better and can more effectively prevent the broken pieces of the nut 200 from splashing during the shelling process.

[0099] The difference between this embodiment and the first embodiment is that the bracket 13, the base 14 and the enclosure 51 of the second embodiment are an integrated structure. That is, the bracket 13, the base 14 and the enclosure 51 of the second embodiment are integrally formed, so that the entire receiving seat 1 is easy to process.

[0100] The two positioning shanks 511 on the inner wall of the enclosure 51 of the second embodiment are two vertically protruding ribs.

[0101] Example 3, please refer to Fig.16 The present embodiment provides a nut shelling device 100c that is easy to use, which differs from the first embodiment in that the upper contact portion 3 of the third embodiment is a shelling knife 41, and the lower contact portion 4 is an anti-skid tip 31. That is, the shelling knife 41 of the third embodiment is installed at the end of the screw 21, and the anti-skid tip 31 is installed on the bracket 13 and is located at the bottom of the shelling groove 11 of the bracket 13. During the positioning process of the nut 200, after the nut 200 is placed in the shelling groove 11, the nut 200 is initially positioned by the side contact portion 5 abutting against the anti-skid tip 31 at the bottom. During the extrusion and shelling process of the nut 200, the shelling knife 41 located at the top moves downward with the screw 21 to extrude the nut 200, and the shell is broken by the penetration of the anti-skid tip 31 and the rotation of the blade 411, and the shelling effect is good.

[0102] Example 4, please refer to Fig.17 This embodiment provides a nut sheller 100d that is easy to use. The difference between the embodiment 1 and the embodiment 1 is that the top of the bracket 13 of the embodiment 4 is provided with a through hole 133, and the top of the bracket 13 is provided with a nut groove 134 below the through hole 133. The nut 9 is arranged in the nut groove 134, and the screw rod 21 is spirally connected with the nut 9. That is, the screw rod 21 of the embodiment 4 is not directly spirally connected with the bracket 13, but is spirally connected with the nut 9 on the bracket 13 to achieve up and down movement, which can avoid spiral wear between the screw rod 21 and the bracket 13 and extend the service life of the bracket 13.

[0103] The nut shelling device 100a, 100b, 100c, 100d of the utility model is easy to use. It is provided with a receiving seat 1 having a shell breaking groove 11 and a spiral extrusion member 2 having a screw 21, wherein the end of the screw 21 is provided with an upper contact portion 3, and the bottom and side of the shell breaking groove 11 are provided with a lower contact portion 4 and a side contact portion 5. One of the upper contact portion 3 and the lower contact portion 4 is an anti-slip top 31, and the other is a shell breaking knife 41 with a raised blade 411. In this way, when positioning the nut 200, the nut 200 is put into the shell breaking groove 11, and the side wall and bottom of the nut 200 are automatically abutted and positioned by the side contact portion 5 and the lower contact portion 4, and the positioning operation is convenient and simple. At the same time, because the anti-slip top 31 can be embedded in the shell of the nut 200 under a small thrust to destroy the shell, combined with the effect of the shell breaking knife 41, the nut shelling device of the utility model can easily complete the shelling of the nut. The shelling is labor-saving and very suitable for girls and children, which improves the user experience. The minimum distance between the anti-skid tip 31 and the shelling knife 41 forms a finger protection gap 7 to prevent the fingers of children or adults from being pinched. At the same time, the anti-skid tip 31 and the shelling knife 41 are set at a reasonable effective height to ensure that the kernel is not damaged during the shelling process and the integrity of the kernel after the shelling is ensured.
