Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of melon seed shelling, in particular to an axially extruded melon seed sheller. Background Art
[0002] Melon seed shellers usually use two parallel rollers as shelling components. When shelling melon seeds, the two rollers are rotated relative to each other, and then the melon seeds are placed vertically between the two rollers. In this way, the rollers will radially press the shell of the melon seeds open during the rotation process to achieve the shelling of the melon seeds. However, different melon seeds have different sizes. If the size of the melon seeds is too large, the melon seed kernels are easily crushed by the two rollers. If the size of the melon seeds is too small, the shell cannot be pressed open by the two rollers.
[0003] There is a melon seed sheller for axially extruding and shelling melon seeds, which is provided with a shelling space and a shelling assembly. After the melon seeds enter the shelling space, they face the shelling assembly axially, and then a driving assembly is used to drive the shelling assembly to axially extrude and shell the melon seeds. During the shelling process, if the melon seeds are small in size, the melon seed kernels can remain intact after the melon seeds are axially extruded and shelled. If the melon seeds are large in size, the slender tip of the melon seed kernels will be broken after the melon seeds are axially extruded and shelled, but the melon seed kernels will not be crushed as a whole, and the melon seed kernels can be kept intact as much as possible. Therefore, regardless of the size of the melon seeds, they can be extruded and shelled without crushing the melon seed kernels. During the axial extrusion and shelling process of the melon seeds, the melon seeds are prone to slipping and radial displacement due to the small contact area between the ends and the shelling assembly, resulting in shelling failure.

[0023] The present invention is further described in detail below in conjunction with specific implementation methods.
[0024] Axial extrusion melon seed sheller Figure 1 As shown, it comprises a first shell 1 and a second shell 2. The second shell 2 has a feeding port 21 adapted to the shape of melon seeds at the top and a discharging port 22 at the front. Figure 2 and Figure 3 As shown, the first shell 1 is provided with two connection buckles 11, and the second shell 2 is provided with two connection holes 12. The two connection buckles 11 and the two connection holes 12 are respectively matched and buckled together to realize the detachable connection between the first shell 1 and the second shell 2. Figure 2 As shown, a driving assembly 3 and a shelling assembly 4 are provided inside the melon seed sheller, and the shelling assembly 4 is located in front of the driving assembly 3, wherein the driving assembly 3 is accommodated in the first shell 1, and the shelling assembly 4 is accommodated in the second shell 2, a feeding port 21 on the second shell 2 leads to the top of the shelling assembly 4, and the bottom of the shelling assembly 4 leads to the discharge port 22 through the material guide channel 13. After the melon seeds enter the melon seed sheller from the feeding port 21, they fall onto the shelling assembly 4, and are discharged from the discharge port 22 through the material guide channel 13 after being shelled by the shelling assembly 4.
[0025] The driving assembly 3 is provided with a control circuit board (not shown in the figure), a driving motor (not shown in the figure) electrically connected to the control circuit board, and a driving gear 31 driven by the driving motor. The driving gear 31 is exposed from the side of the driving assembly 3 facing the shelling assembly 4. A switch button 14 electrically connected to the control circuit board is provided at the rear end of the first housing 1. The user operates the switch button 14 to control the opening and closing of the driving motor through the control circuit board. The shelling assembly 4 includes a first roller 43 and a second roller 44 arranged in parallel. The first roller 43 and the second roller 44 are located below the feeding port 21. The first roller 43 and the second roller 44 are each coaxially mounted with a transmission gear 45. The two transmission gears 45 are meshed with each other. When one of the first roller 43 and the second roller 44 rotates, the other is driven to rotate in the opposite direction through the two transmission gears 45.
[0026] A reinforcement structure is provided between the driving assembly 3 and the shelling assembly 4, as shown in FIG. Figure 2 and Figure 3 As shown, the driving assembly 3 is provided with two fixed buckles 5 and a slot 8, and the shelling assembly 4 is provided with two buckle holes 6 and a movable buckle 7. The two fixed buckles 5 are buckled together with the two buckle holes 6, and the movable buckle 7 is buckled together with the slot 8, so as to form a reinforcement structure that detachably connects the driving assembly 3 and the shelling assembly 4. The reinforcement structure will reinforce the transmission connection between the shelling assembly 4 and the driving assembly 3 to avoid being stretched open, and keep the driving assembly 3 driving the shelling assembly 4 to shell the melon seeds. After the reinforcement structure connects the driving assembly 3 and the shelling assembly 4 together, the driving gear 31 is meshed with the transmission gear 45 of the first roller 43. Since the transmission gear 45 of the first roller 43 and the transmission gear 45 of the second roller 44 are meshed with each other, the driving assembly 3 can drive the two transmission gears 45 to rotate in opposite directions through the driving gear 31, thereby driving the first roller 43 and the second roller 44 to rotate in opposite directions.
[0027] like Figure 4 As shown, an operating member 71 is provided on the movable buckle 7, the bottom of the operating member 71 extends out of the shelling assembly 4, and a reset spring 72 is installed on the top. When the shelling assembly 4 needs to be disassembled from the driving assembly 3, the user presses the operating member 71 upward to drive the movable buckle 7 to move up and disengage from the slot 8 to achieve disengagement, and then the two fixed buckles 5 and the two buckle holes 6 can be operated to release the disengagement, so as to achieve the disassembly of the shelling assembly 4 and the driving assembly 3.
[0028] like Figure 4As shown, the first roller 43 and the second roller 44 each have a groove, the groove wall of the groove of the first roller 43 facing the second roller 44 is a first pressing structure 41 for pressing the head end of the melon seeds, the groove wall of the groove of the second roller 44 facing the first roller 43 is a second pressing structure 42 for pressing the tail end of the melon seeds, and the space between the first pressing structure 41 and the second pressing structure 42 is a storage space for accommodating melon seeds. Figure 5 As shown, the feeding port 21 is adapted to the shape of melon seeds, and the melon seeds are placed in a direction with the head end facing backward and the tail end facing forward, and fall into the accommodating space of the shelling component 4. In the shelling component 4, the first roller 43 is located at the rear, and the second roller 44 is located at the front, as shown in FIG. Figure 7 As shown, the head end of the melon seeds is sunk into the groove of the first roller 43 and faces the first pressing structure 41, and the tail end of the melon seeds is sunk into the groove of the second roller 44 and faces the second pressing structure 42. The driving component 3 drives the first roller 43 and the second roller 44 to rotate toward each other to drive the first pressing structure 41 and the second pressing structure 42 to move toward each other, and axially squeeze and shell the melon seeds. In this way, the squeezing direction of the axial squeezing and shelling of the melon seeds by the shelling component 4 is specifically the direction in which the first pressing structure 41 and the second pressing structure 42 move toward each other, that is, the tangential direction of the rotation of the two rollers 43 and 44, corresponding to Figure 5 and Figure 6 The directions of arrows A and B.
[0029] like Figure 5 As shown, the first pressing structure 41 is recessed in a direction away from the second pressing structure 42, and the second pressing structure 42 is recessed in a direction away from the first pressing structure 41. The deepest recessed position 411 of the first pressing structure 41 and the deepest recessed position 422 of the second pressing structure 42 are staggered in the extrusion direction. Figure 6 As shown, the distance L between the projections of the deepest depression 411 and the deepest depression 422 on the plane perpendicular to the extrusion direction is 1 cm. In this way, when the first pressing structure 41 and the second pressing structure 42 move toward each other to axially press and shell the melon seeds, the head end of the melon seeds will be offset in the first pressing structure 41 to face the deepest depression 411, and the tail end of the melon seeds will be offset in the second pressing structure 42 to face the deepest depression 421, so that the melon seeds are slightly deflected laterally. Figure 7 The state shown is deflected into Figure 8In the state shown, the axial direction of the melon seeds corresponds to the straight line direction passing through the deepest depression 411 of the first pressing structure 41 and the deepest depression 421 of the second pressing structure 42, so that the shelling assembly 4 axially squeezes the melon seeds in the accommodating space, and there is an angle difference of 15° between the squeezing direction of the shelling and the axial direction of the melon seeds. Then the first roller 43 and the second roller 44 continue to rotate towards each other, so that the first pressing structure 41 and the second pressing structure 42 continue to move towards each other, so as to apply the following pressure to the head and tail ends of the melon seeds respectively. Figure 8 The extrusion pressure in the direction indicated by the arrow, that is, the extrusion pressure applied by the first pressing structure 41 to the head end of the melon seeds has an axial extrusion pressure component (corresponding to the direction of arrow C1) and a radial extrusion pressure component (corresponding to the direction of arrow C2), and the extrusion pressure applied by the second pressing structure 42 to the tail end of the melon seeds also has an axial extrusion pressure component (corresponding to the direction of arrow D1) and a radial extrusion pressure component (corresponding to the direction of arrow D2). In this way, compared with only applying axial extrusion pressure to the melon seeds, only a smaller extrusion force needs to be applied to press the melon seeds open and shell them by simultaneously applying axial and radial extrusion on the melon seeds.
[0030] It should be noted that the projection distance between the deepest depression 411 of the first pressing structure 41 and the deepest depression 421 of the second pressing structure 42 on the plane perpendicular to the extrusion direction may be other distances not greater than 2 cm. The shelling assembly 4 axially extrudes the melon seeds in the accommodating space, and the angle difference between the extrusion direction of the melon seeds and the axial direction of the melon seeds may be other angle differences not greater than 45°.
[0031] When the shelling component 4 needs to be cleaned, the user can first press the two connecting buckles 11 on the first shell 1 to disengage them from the two connecting buckles 12 on the second shell 2, and then remove the second shell 2 from the first shell 1; then press the operating piece 71 on the shelling component 4 upward to drive the movable buckle 7 to move upward, so that the movable buckle 7 disengages from the slot 8 on the drive component 3 to achieve disengagement, and then the two fixed buckles 5 and the two buckle holes 6 can be loosened and disengaged, so that the shelling component 4 and the drive component 3 can be disassembled and separated, and the shelling component 4 can be cleaned alone, and the drive component 3 will not be damaged due to cleaning. In this embodiment, in order to avoid the risk of pinching fingers when the driving component 3 can still drive the shelling component 4 after the second shell 2 is removed, a protection switch 9 electrically connected to the control circuit board is provided on the driving component 3, and a touch rod 10 for the user to touch the protection switch 9 is provided on the second shell 2. When the second shell 2 is connected to the first shell 1, the touch rod 10 on the second shell 2 passes through the shelling component 4 and contacts the protection switch 9 on the driving component 3, so that the control circuit board can pass through. After the second shell 2 is detached from the first shell 1, the touch rod 10 on the second shell 2 no longer contacts the protection switch 9 on the driving component 3, and the control circuit board triggers the protection mechanism to prevent the driving motor from starting, thereby preventing the driving component 3 from driving the shelling component 4, eliminating the risk of pinching fingers.
[0032] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
