Description

Technical Field

[0001] This disclosure belongs to the field of household nut shelling technology, and particularly relates to a sunflower seed shelling device. Background Technology

[0002] A sunflower seed shell-opening device squeezes the shells of sunflower seeds to crack them open and expose the kernels. Generally, this device has a container for holding the seeds, with an opening at the top for the user to place the seeds into the container. The seeds are then squeezed open within the container. For some highly processed sunflower seeds (such as fragrant or caramel-flavored seeds), the shell toughness is greatly reduced while brittleness increases. During the shell-breaking process, fragments of the shell can easily fly out from the opening of the container, leading to poor hygiene and potentially inhaling into the user's respiratory tract or eyes. To balance the need for seed placement with the need to prevent splashing, a sliding door might be needed to open before seeds are placed in and close afterward. However, this would likely require a complex structure or increase operational complexity. Summary of the Invention

[0003] The present disclosure aims to provide a sunflower seed shell-opening device that reduces the splashing of sunflower seed shells during use.

[0004] In one aspect, a sunflower seed shelling device is provided, which includes a first extruder, a second extruder, and a baffle. The outer peripheral surface of the first extruder is provided with a first concave corner, the first concave corner including an intersecting first supporting surface and a first limiting surface; the outer peripheral surface of the second extruder is provided with a second concave corner, the second concave corner including an intersecting second supporting surface and a second limiting surface; a baffle is provided on the first extruder and has at least a portion of its structure located above the first concave corner; wherein, the first extruder and the second extruder are configured to rotate from their respective initial positions to their respective target positions; in the initial position, the first concave corner and the second concave corner form an accommodating space with an upward opening, the first supporting surface and the second supporting surface are used to support a horizontally placed sunflower seed, and at least a portion of the structure of the baffle blocks the upward opening; during the rotation to the target position, the first concave corner and the second concave corner move closer to each other, and the junction of the first supporting surface and the first limiting surface restricts and compresses one end of the sunflower seed and the junction of the second supporting surface and the second limiting surface is used to restrict and compress the other end of the sunflower seed, and the baffle gradually blocks at least a portion of the upward opening.

[0005] In one possible implementation, during the process of turning to the target position, the baffle gradually blocks at least a portion of the upward opening and then enters the second concave corner.

[0006] In combination with the above possible implementations, in another possible implementation, the baffle extends obliquely upward.

[0007] In combination with the above possible implementations, in another possible implementation, the surface of the baffle facing the accommodating space is concave arc-shaped.

[0008] In combination with the above possible implementations, in another possible implementation, the surface of the baffle facing away from the accommodating space is convex arc-shaped.

[0009] In combination with the above possible implementations, in another possible implementation, the baffle is an arc-shaped piece with its concave surface facing the accommodating space.

[0010] In combination with the above possible implementations, in another possible implementation, the baffle points downwards at the target position.

[0011] In combination with the above possible implementations, in another possible implementation, at the target position, at the initial position, the first supporting surface of the first concave corner is lower than the second supporting surface of the second concave corner.

[0012] In combination with the above possible implementations, in another possible implementation, the angle from the initial position to the target position is greater than 70 degrees.

[0013] In combination with the above possible implementations, in another possible implementation, there is no substantial interference between the baffle and the second extruder during the process of the first extruder rotating to the target position.

[0014] In addition to the above possible implementations, another possible implementation also includes a rod fixed to the first extruder to provide a lever arm for driving the first extruder to rotate.

[0015] In combination with the above possible implementations, in another possible implementation, the rod extends obliquely upward relative to the accommodating space, and moves above the accommodating space as the first extruder rotates.

[0016] In combination with the above possible implementations, in another possible implementation, in the initial position, the end of the first supporting surface is lower than the end of the second supporting surface.

[0017] In combination with the above possible implementations, in another possible implementation, the first extruder is a roller with a circumferential surface, the second extruder is a roller with a circumferential surface, the sum of the radii of the circumferential surfaces of the first extruder and the second extruder is less than the center distance between them, and the first extruder is provided with a protrusion extending out of the circumferential surface, the side of the protrusion forming part of the first support surface.

[0018] In combination with the above possible implementations, in another possible implementation, in the initial position, the end of the baffle and the top of the second limiting surface of the second extruder define an entrance into the receiving space.

[0019] According to the sunflower seed shell-opening device provided in this disclosure, by means of a baffle provided in the first extruder, the upward opening of the accommodating space can be blocked during the extrusion of the sunflower seeds to prevent the sunflower seed shells from popping out; and in the initial position, the baffle will not completely cover the upward opening, so as not to prevent the user from putting the sunflower seeds into the accommodating space.

Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0038] Features and exemplary embodiments of various aspects of this disclosure will now be described in detail. Numerous specific details are set forth in the following detailed description in order to provide a thorough understanding of this disclosure. However, it will be apparent to those skilled in the art that this disclosure may be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this disclosure by illustrating examples. This disclosure is by no means limited to any specific structures and configurations set forth below, but covers any modifications, substitutions, and improvements to parts, components, and connection methods without departing from the spirit of this disclosure. Well-known structures and techniques are not shown in the accompanying drawings and the following description in order to avoid unnecessarily obscuring this disclosure.

[0039] Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this disclosure.

[0040] The sunflower seed shelling device disclosed herein includes a first extruder, a second extruder, and a baffle. The outer peripheral surface of the first extruder has a first concave corner, which includes an intersecting first supporting surface and a first limiting surface. The outer peripheral surface of the second extruder has a second concave corner, which includes an intersecting second supporting surface and a second limiting surface. The baffle is disposed on the first extruder and has at least a portion of its structure located above the first concave corner. The first and second extruders are configured to rotate from their respective initial positions to their respective target positions. In the initial position, the first and second concave corners form an upwardly opening receiving space, the first and second supporting surfaces are used to support horizontally placed sunflower seeds, and at least a portion of the baffle's structure obstructs the upward opening. During the rotation to the target position, the first concave corner and the second concave corner move closer to each other, and the junction of the first supporting surface and the first limiting surface restricts and squeezes one end of the sunflower seed, while the junction of the second supporting surface and the second limiting surface restricts and squeezes the other end of the sunflower seed. The baffle gradually blocks at least a portion of the upward opening. The sunflower seed shelling device provided in this disclosure has a baffle provided on the first extruder. The baffle can move with the first extruder, so that it does not completely block the upward opening of the accommodating space in the initial position, so that the user can place the sunflower seed; while during the rotation of the first extruder, it gradually completely blocks the upward opening of the accommodating space, preventing the fragments from flying upward when the sunflower seed is squeezed and broken.

[0045] The sunflower seed shelling device provided in this disclosure is based on the principle that two extruders squeeze both ends of the sunflower seed. For specific structure and principle, please refer to the prior art, such as Chinese patents ZL202323243168.9, ZL202421947852.7, and ZL202422025190.4 (all of which are incorporated herein by reference). In the aforementioned prior art, when the sunflower seed is crushed by the first and second extruders in the accommodating space, fragments of the sunflower seed shell may fly outwards from the upward opening of the accommodating space.

[0046] The sunflower seed shell-opening device includes a first extruder 100, a second extruder 200, a support 300, a rod 400, and a shell 500, wherein the first extruder 100 is provided with a baffle 120. Specifically, the first extruder 100 and the second extruder 200 are rotatably mounted on the support 300 via pins. The first extruder 100 and the second extruder 200 are engaged by a gear structure, and the second extruder 200 can move accordingly when the first extruder 100 rotates. One end of the rod 400 is fixed to the first extruder 100, and the other end is for the user to hold, providing a lever arm to drive the first extruder 100 to rotate. The rod extends obliquely upward relative to the receiving space 10, and the rod 400 moves above the receiving space 10 as it rotates with the first extruder 100. In this way, it is difficult to set a baffle on the shell 500 to prevent the sunflower seed shells from popping out, because when the rod 400 is pressed down, it will be directly above the receiving space 10 (e.g., Figure 7 As shown, setting a baffle will interfere with rod 400. Offsetting rod 400 along the axial direction of the first extruder 100 makes it difficult to obtain the best appearance and layout.

[0047] The outer casing 500 covers the first extruder 100, the second extruder 200, and the support 300. An opening at the top exposes the accommodating space 10 of the first extruder 100 and the second extruder 200, and provides space for the rod 400. An outlet is located on the lower side of one side of the outer casing 500 to discharge the crushed sunflower seed shells and kernels.

[0048] like Figure 3As shown, the first extruder 100 and the second extruder 200 are extrusion rollers with circumferential surfaces. The first concave corner 110 and the second concave corner 210 are approximately right-angled corners formed by downward and downward indentation from the circumferential surfaces. In their initial positions, the first concave corner 110 of the first extruder 100 and the second concave corner 210 of the second extruder 200 form a receiving space 10, which has an upward opening 11. Specifically, the first concave corner 110 is approximately an L-shaped groove, including a first supporting surface 111 extending in a first direction and a first limiting surface 112 extending in a second direction, and a first junction 113 formed by their intersection. Similarly, the second concave corner 210 is approximately an L-shaped groove, including a second supporting surface 211 extending in a first direction and a second limiting surface 212 extending in a second direction, and a second junction 213 formed by their intersection. The first concave corner 110 and the second concave corner 210 are approximately mirror-symmetrically arranged. The first supporting surface 111 and the second supporting surface 211 form the bottom surface of the accommodating space 10, which can be used to place sunflower seeds (shown by dashed lines in the figure) lying down. Figure 7 The diagram illustrates the first extruder 100 and the second extruder 200 in their target positions. In the target position, the opening of the accommodating space formed by the first concave corner 110 and the baffle 120 faces downwards, allowing the contents to fall in. The accommodating space 10 is a space whose shape deforms as the first extruder 100 and the second extruder 200 rotate. In the initial position, the opening of the accommodating space 10 faces upwards, suitable for inserting sunflower seeds; in the target position, the opening of the accommodating space 10 faces downwards, suitable for the sunflower seed shells and kernels to fall out.

[0049] A baffle 120 is disposed on the first extruder 100, extending obliquely upward from the junction of the first limiting surface 112 of the first concave corner 110 and the circumferential surface. In the initial position, at least a portion of the structure of the baffle 120 obstructs the upward opening 11. Figure 1 and Figure 3 As shown, although the baffle 120 blocks part of the upward opening 11 of the accommodating space 10, there is still enough space between the end of the baffle 120 and the top of the second limiting surface 212 for the sunflower seeds to enter the accommodating space 10.

[0050] During the process of the first extruder 100 rotating to the target position, the first concave corner 110 and the second concave corner 210 move closer to each other, and the first junction 113 of the first supporting surface 111 and the first limiting surface 112 restricts and compresses one end of the sunflower seed, the second junction 213 of the second supporting surface 211 and the second limiting surface 212 restricts and compresses the other end of the sunflower seed, and the baffle 120 gradually blocks at least a portion of the upward opening 11. Figure 2 and Figure 4As shown, the baffle 120 can block the upward opening 11 during the process of squeezing the sunflower seeds, and the fragments that splash out when the sunflower seed shell breaks can be blocked by the baffle 120 and cannot fly upward.

[0051] like Figure 6 and Figure 7 As shown, when the first extruder 100 rotates further towards the target position, the baffle 120 can enter the interior of the accommodating space 10 (in the second concave corner 210). The baffle 120 will not substantially interfere with the second extruder 200 (e.g., no contact or minimal interference, the elastic deformation of the baffle 120 will not completely block the relative rotation of the first extruder 100 and the second extruder 200). Thus, at the target position, the baffle 120 points downwards, which can also push the sunflower seed shells remaining in the accommodating space 10 after extrusion downwards, preventing the sunflower seed shells from getting stuck in the accommodating space 10 and hindering the next insertion of sunflower seeds.

[0052] In this embodiment, the baffle 120 is generally an arc-shaped plate, extending obliquely upward in a form that is approximately tangential to the first limiting surface 112. The baffle 120 has an outer surface 121 and an inner surface 122. The outer surface 121 faces away from the first concave corner 110, and the inner surface 122 faces the first concave corner 110. Both the outer surface 121 and the inner surface 122 are arc-shaped. Compared to a straight plate shape, the arc-shaped baffle 120, with its arc-shaped inner surface 122, provides a larger space between itself and the first supporting surface 111, facilitating the containment of the sunflower seed shells that expand during the compression process and preventing the sunflower seed kernels from being crushed. In some alternative embodiments, the baffle 120 can be a straight plate shape. The arc-shaped outer surface 121 is less likely to interfere with the second concave corner 210 during its entry into the second concave corner 210.

[0053] refer to Figure 9In the initial position, the end of the baffle 120 and the top of the second limiting surface 212 of the second extruder 200 define an entrance into the receiving space 10. The first supporting surface 111 of the first concave corner 110 is lower than the second supporting surface 211 of the second concave corner 210. This allows the seeds to enter the receiving space 10 from the entrance defined by the end of the baffle 120 and the top of the second supporting surface 211 without being blocked by the gap between the second supporting surface 211 and the first supporting surface 111, making it easier for them to slide into the receiving space 10. In this embodiment, the first supporting surface 111 is extended by providing a radially protruding protrusion 114 on the circumferential surface of the first extruder 100. The protrusion 114 is disposed adjacent to the end of the first supporting surface 111, its surface is flush with the first supporting surface 111, and the side of the protrusion 114 forms part of the first supporting surface 111. The first extrusion component is a roller with a circumferential surface, and the second extrusion component is a roller with a circumferential surface. The sum of the radii of the circumferential surfaces of the first extrusion component and the second extrusion component is less than the center distance between them, so there is a gap between the circumferential surfaces of the two rollers. By providing the protrusion 114, the gap between the two is closed to prevent the gap from blocking the sunflower seeds from sliding into the receiving space 10 or falling into the gap.

[0054] The angle from the initial position to the target position is greater than 70 degrees. The accommodating space 10 can only form a sufficiently large downward opening in the target pose when the first extruder 100 and the second extruder 200 rotate at a sufficiently large angle. When the aforementioned angle is large, the stroke of the rod 400 is large, and during the downward pull, it will block the upward opening 11 of the accommodating space 10 at its extreme position.

[0055] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this disclosure, and these modifications or substitutions should all be covered within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
