[0040] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0041] like Figures 1 to 9As shown, an embodiment of the present invention discloses a device for cracking sunflower seeds 1000. The device includes: a frame 90, a conveying mechanism 100, a peeling mechanism 200, a blower mechanism 60, a receiving trough 71, and a waste trough 72, all of which are attached to the frame 90. The conveying mechanism 100 is used to convey the sunflower seeds 1000 to be processed to the peeling mechanism 200. The peeling mechanism 200 is used to receive the sunflower seeds 1000 to be processed and to remove the kernels from the shells. The blower mechanism 60 separates the kernels from the shells by providing airflow. The receiving trough 71 is used to collect the kernels, and the waste trough 72 is used to collect the shells.

[0042] Before introducing the various components of the device, it is necessary to describe and define the shape and structural features of the Guazi 1000:

[0043] A melon seed 1000 consists of melon seed shells and melon seed kernels located inside the shells. The melon seed shells are composed of two interlocking outer shells. The distance between the two ends of the melon seed shells along their length can be called the length of the melon seed 1000, the width of the melon seed shells can be called the width of the melon seed 1000, and the distance between the highest bulges of the two melon seed shells can be called the thickness of the melon seed 1000. The interlocking of the two melon seed 1000 shells forms an edge in the width direction, which can be called the edge of the melon seed 1000. A conjoined melon seed 1000 specifically refers to two melon seed 1000 shells that are connected to each other, so that the two melon seed 1000 shells are stacked in the thickness direction.

[0044] The conveying mechanism 100 includes: a storage tank, a temporary storage tank 16, and a conveying assembly 20.

[0045] like Figure 1 As shown, the storage tank has an inlet 11 at the top and a side-facing outlet 12 at the bottom. Sunflower seeds 1000 to be processed are stored in the storage tank through the inlet 11 and discharged through the outlet 12 for transport to a higher position by the conveying assembly 20. An inclined guide plate 13 is arranged in the storage tank to allow the sunflower seeds 1000 to flow downwards at an angle. A throttling plate 14 with a smaller inclination angle than the guide plate 13 is disposed at the lower end of the guide plate 13. This throttling plate 14 and the side wall of the storage tank define a throttling orifice 15, which throttles the flow of sunflower seeds 1000, thereby preventing a large amount of sunflower seeds 1000 from accumulating at the outlet 12.

[0046] A temporary storage trough 16 is arranged at the lower edge of the discharge port 12. The bottom of the temporary storage trough 16 is lower than the lower edge of the discharge port 12, and the width of the bottom of the trough is less than the length of the sunflower seeds 1000. This makes the sunflower seeds 1000 as close as possible to the extension of the temporary storage trough 16, which is conducive to the sunflower seeds 1000 being conveyed in a horizontal position by the conveying assembly 20 described below.

[0047] like Figure 1 and combined Figure 3 As shown, the temporary storage groove 16 is formed by a series of spaced-out toothed hooks, which may be referred to as second toothed hooks 161. The second toothed hooks 161 have tooth gaps between them.

[0048] like Figure 1 , Figure 3 , Figure 6 As shown, the conveying assembly 20 is used to receive the sunflower seeds 1000 in the temporary storage tank 16 and convey the sunflower seeds 1000 to a higher position. The conveying assembly 20 includes: an inner support component 22 and a conveyor belt 21; the inner support component 22 is arranged vertically at an inclination, and therefore, the inner support component 22 has an upper end and a lower end that are not in the same vertical plane. The lower end of the inner support component 22 is close to the temporary storage tank 16, and the upper end of the inner support component 22 is away from the temporary storage tank 16 in the horizontal direction. Conveying rollers 23 are installed at both the upper and lower ends of the inner support component 22, wherein at least one conveying roller 23 serves as a drive roller. The conveyor belt 21 is sleeved on the inner support component 22 and driven by the conveying roller 23 so that the belt body of the conveyor belt 21 moves from bottom to top toward the side of the temporary storage tank 16.

[0049] In this invention, a plurality of spaced-apart support portions 211 are arranged on the conveyor belt 21 along the length direction. The support portions 211 are formed by a toothed hook (which may be called a first toothed hook 2111) spaced-apart in the width direction. When the support portion 211 passes through the temporary storage groove 16, the first toothed hook 2111 of the support portion 211 and the second toothed hook 161 of the temporary storage groove 16 pass through each other's gaps, so that the support portion 211 passes through the temporary storage groove 16 in an alternating manner. Thus, when the support portion 211 moves with the conveyor belt 21 and passes through the temporary storage groove 16, the sunflower seeds 1000 on the temporary storage groove 16 are supported by the first toothed hook 2111 on the support portion 211 and move upward with the conveyor belt 21.

[0050] In this invention, the support groove of the support part 211 is configured in a V shape, which makes it easy for the sunflower seed 1000 to be supported with one of its edges located in the support groove. Since the conveyor belt 21 is in an inclined state, the sunflower seed 1000 can easily rest against it, thereby making it easy for the sunflower seed 1000 to be kept in a horizontal position with one of its edges located in the support groove. In this way, the sunflower seed 1000 can be transported stably.

[0051] In this invention, the distance between any two adjacent support portions 211 is less than the length of the sunflower seed 1000 (the number of support portions 211 shown in the drawings is small, and the distance between any two adjacent support portions 211 is large, which is for the purpose of simplifying the drawing. In fact, the distance between any two adjacent support portions 211 is much smaller than the length of the sunflower seed 1000 and slightly larger than the width of the sunflower seed 1000). Thus, when the sunflower seed 1000 in the temporary storage tank 16 is supported by the support portion 211, the horizontally placed sunflower seed 1000 is allowed to fall on the support portion 211, while the vertical sunflower seed 1000 is interfered with by the upper support portion 211 due to the small distance between the two support portions 211 and is not allowed to fall on the support portion 211. This makes it possible for the vertical sunflower seed 1000, which is difficult to be stably conveyed, to not be conveyed by the conveyor belt 21.

[0052] In this invention, the conveyor belt 21 is provided with a plurality of partition ribs 212 arranged at intervals along its width direction. The distance between any two adjacent partition ribs 212 is greater than one time the length of the sunflower seed 1000 but less than twice the length of the sunflower seed 1000. Thus, the area where the partition ribs 212 are located is not allowed to have sunflower seeds 1000 fall on it. The sunflower seeds 1000 can only be located on the support portion 211 between any two adjacent partition ribs 212, and only one sunflower seed 1000 is allowed to be located on it. In this way, the sunflower seeds 1000 are conveyed by the conveyor belt 21 in a manner divided into multiple columns.

[0053] In this invention, sunflower seeds 1000 are transported in multiple rows by conveyor belt 21 to the top of conveyor assembly 20. An interference plate 24 is arranged on one side of conveyor belt 21, inclined towards conveyor belt 21 such that its free end is close to conveyor belt 21. When sunflower seeds 1000 are transported by conveyor belt 21 and pass the free end of interference plate 24, if the sunflower seeds 1000 are conjoined, their greater thickness may cause them to contact interference plate 24. In this case, interference plate 24 obstructs the contact with conjoined seeds, sunflower seeds with larger widths, and irregularly shaped seeds, making them less likely to (or) come into contact with interference plate 24. Peeled sunflower seeds 1000 (not suitable for transport) detach from the support portion 211 (specifically, the first toothed hook 2111), thereby preventing the whole sunflower seeds 1000 from being conveyed to the top of the conveying assembly 20. If the sunflower seeds 1000 are in a horizontal position but the edges of the sunflower seeds 1000 are not located in the V-shaped groove 4112 of the support portion 211, the interference plate 24 pushes the sunflower seeds 1000 back into the correct position by contacting them, that is, adjusting the sunflower seeds 1000 to a horizontal position where the edges are located in the V-shaped groove 4112, which is the desired conveying position. Preferably, the free end of the interference plate 24 is configured with spaced teeth to reduce the bending stiffness of the free end.

[0054] In this invention, an interference bar 25 is arranged above the top of the conveying assembly 20. The interference bar 25 has an arcuate surface 251 facing the conveyor belt 21 and aligned with the conveyor belt 21. The sunflower seeds 1000 conveyed to the top by the conveyor belt 21 pass through the gap between the arcuate surface 251 of the interference bar 25 and the conveyor belt 21. If the sunflower seeds 1000 are large in shape, for example, thicker single sunflower seeds 1000 or thicker connected sunflower seeds 1000 (which do not fall off the support portion 211 when passing the interference plate 24), the sunflower seeds 1000 are crushed by the interference bar 25 when passing through the gap. Such sunflower seeds 1000 are not the sunflower seeds 1000 that are desired to be processed. Preferably, the interference bar 25 is provided with a plurality of clearance grooves, which are respectively opposite to a plurality of separating ribs 212 on the conveyor belt 21. The clearance grooves are used to avoid the separating ribs 212 to prevent interference between the separating ribs 212 and the interference bar 25. Preferably, each partition rib 212 is provided with stress relief slots arranged at intervals along its length. When the conveyor belt 21 moves to the conveyor roller 23 and undergoes an arc-shaped bend to adapt to the conveyor roller 23, the stress relief slots can greatly reduce the internal stress of the partition rib 212, thereby preventing the partition rib 212 from deforming in a way that does not conform to the arc-shaped bend of the conveyor belt 21.

[0055] like Figure 1 , Figure 3 , Figure 7 , Figure 8 As shown, the peeling mechanism 200 is used to receive multiple rows of sunflower seeds 1000 to be processed that are conveyed to the top by the conveying assembly 20 and then remove the kernels of the sunflower seeds 1000 from their shells. The peeling mechanism 200 includes: a guiding component 30, a peeling mechanism 40, and an auxiliary separation mechanism 50.

[0056] The tapping mechanism 40 includes two pressure-applying components 41. Each pressure-applying component 41 includes a support body 413 with drive rollers 412 arranged at both ends, and a pressure belt 411 sleeved on the support body 413 and driven by the drive rollers 412. The two pressure-applying components 41 are arranged vertically at opposite angles, and the distance between the lower ends of the two pressure-applying components 41 is smaller than the distance between the upper ends, thus the two pressure belts 411 are arranged at an angle. Each pressure belt 411 is provided with a plurality of toothed ribs 4111 arranged along its length. Because the two pressure belts 411 are arranged at an angle, the toothed ribs 4111 on the two pressure belts 411 enter each other's tooth gaps at the lower part, thereby bringing the bodies of the two pressure belts 411 as close as possible at the lower part. Preferably, the toothed ribs 4111 are made of rubber or silicone material.

[0057] Each pressure belt 411 has a toothed rib 4111 with a plurality of corresponding V-shaped grooves 4112 extending along the length of the pressure belt 411 and spaced apart in the width direction. Each pair of corresponding V-shaped grooves 4112 defines a squeezing chamber 4113. Thus, the two pressure belts 411 define a plurality of squeezing chambers 4113 spaced apart in the width direction. These plurality of squeezing chambers 4113 correspond to the multiple rows of sunflower seeds 1000 on the conveyor belt 21 of the aforementioned conveying assembly 20. Furthermore, the two pressure belts 411 move from top to bottom.

[0058] Since the two pressure belts 411 are vertically inclined relative to each other, in the conveying direction of the pressure belts 411, that is, from top to bottom, every two opposing V-shaped grooves 4112 that form the extrusion cavity 4113 gradually approach each other, thereby causing the extrusion cavity 4113 to gradually decrease in size.

[0059] The guide component 30 is configured in a wedge shape that is larger at the top and smaller at the bottom, and is arranged between the top of the conveying assembly 20 and the tapping mechanism 40. The lower end of the guide component 30 extends into the angle defined by the two pressure belts 411, and the upper end of the guide component 30 is slightly lower than the top of the conveying assembly 20 and adjacent to the conveyor belt 21 of the conveying assembly 20. Multiple guide channels 33 are provided in the guide component 30 at intervals. The multiple guide channels 33 correspond one-to-one with multiple rows of sunflower seeds 1000 on the conveyor belt 21 and one-to-one with multiple extrusion chambers 4113 on the peeling mechanism 40. The guide channels 33 extend to the upper end of the guide component 30 to form an inlet port 31 and extend to the lower end of the guide component 30 to form a drop port 32. The cross-section of the guide channel 33 decreases from top to bottom and finally matches the cross-section of the extrusion chamber 4113. Furthermore, the inlet port 31 of the guide channel 33 has sufficient size in the width direction to allow the sunflower seeds 1000 to enter the guide channel 33 laterally from the inlet port 31.

[0060] Sunflower seeds 1000 in a horizontal position on each column conveyed to the top by conveyor belt 21 enter the guide channel 33 through the feed port 31. Under the action of gravity, the sunflower seeds 1000 fall along the guide channel 33. The guide channel 33 with a gradually changing cross section corrects the posture of the falling sunflower seeds 1000 so that the sunflower seeds 1000 finally enter the upper section of the extrusion chamber 4113 from the drop port 32 of the guide channel 33 with the two edges facing the apex of the two V-shaped grooves 4112 that form the extrusion chamber 4113. Subsequently, the sunflower seeds 1000 move downward with the pressure belt 411. As the extrusion chamber 4113 decreases in size by the two V-shaped grooves 4112 approaching each other, the cavity wall of the extrusion chamber 4113 applies force to the edges of the sunflower seeds 1000 in the width direction, thereby causing the two interlocking outer shells of the sunflower seeds 1000 to separate, that is, the sunflower seed shells are cracked open.

[0061] In some preferred configurations, the root of each first tooth 2111 of the support portion 211 is configured to be hollow to reduce the bending stiffness of the first tooth 2111. Preferably, the support portion 211 is made of a flexible material such as rubber or silicone.

[0062] Preferably, the distance between the drive rollers 412 at the lower ends of the two pressure components 41 is configured to be adjustable to accommodate sunflower seeds 1000 of different sizes.

[0063] In some preferred configurations, the upper end of the guide component 30 has an outer edge 34. A mounting plate 36 is fixed on the frame 90 at a position opposite to the bottom of the outer edge 34. Two magnetic plates 35 with opposite magnetic poles are installed on the bottom of the outer edge 34 and on the mounting plate 36. A driven rotating toothed bar 37 is installed on the frame 90 below the outer edge 34. The toothed bar 37 has teeth. By driving the toothed bar 37, the guide component 30 can be moved upward, and the guide component 30 can be moved upward and then fall back to its original position by magnetic attraction, thereby enabling the guide component 30 to produce vertical vibration. In this way, by making the toothed bar 37 rotate in real time with the operation of the conveying mechanism 100 and the peeling mechanism 200, the guide component 30 can be vertically vibrated in real time, thereby effectively reducing the probability of the sunflower seeds 1000 getting stuck and helping the sunflower seeds 1000 to fall back to their original position.

[0064] An auxiliary separation mechanism 50 is arranged below the shelling mechanism 40. This auxiliary separation mechanism 50 includes two force rollers 51 arranged in parallel. Each force roller 51 has an elastic friction layer on its surface, for example, made of rubber or silicone. The two force rollers 51 rotate towards each other, creating a speed difference between them. When the sunflower seeds 1000, after being processed by the shelling mechanism 40, fall between the two force rollers 51 and pass through the gap between them, the speed difference between the two force rollers 51 causes them to rub and knead the sunflower seeds 1000, thereby separating the adhered shells from the kernels.

[0065] Preferably, the elastic friction layer is a silicone layer or a rubber layer; the outer surface of the elastic friction layer is configured with spaced-apart annular winglets (not shown in the figure) in the section for receiving the sunflower seeds 1000. The function of the annular winglets is: on the one hand, to make the gap between the two force rollers 51 variable, thereby conforming to the size of the sunflower seeds 1000; on the other hand, to improve the crushing effect on the sunflower seeds 1000.

[0066] The blower mechanism 60 is arranged on one side below the auxiliary separation mechanism 50. The blower mechanism 60 includes a fan 62, which provides a lateral airflow to the sunflower seeds 1000 after they have passed through the auxiliary separation mechanism 50. This causes the sunflower seed shells to change their falling trajectory along the direction of the airflow, so that the sunflower seed shells are received by the waste trough 72 and the sunflower seed kernels fall into the collection trough 71.

[0067] The waste trough 72 is located on the side where the airflow blows, so as to receive the sunflower seed shells whose falling trajectory is changed by the airflow. Specifically, the waste trough 72 is located below the storage tank 10 mentioned above. Preferably, an air guide shell 65 is arranged between the blower mechanism 60 and the waste trough 72. The air guide shell 65 has a certain height, so as to restrict the airflow from blowing directly onto the sunflower seed shells that have been collected in the waste trough 72.

[0068] Preferably, the waste trough 72 has a side wall with a window 721, in which a mesh is arranged to increase the storage volume of the waste trough 72, and the mesh is used to allow airflow to pass through. Preferably, the waste trough 72 is detachably assembled with the frame 90 by magnetic attraction, so that the waste trough 72 can be removed and the sunflower seed shells poured out after it is full.

[0069] The receiving trough 71 is located diagonally below the auxiliary separation mechanism 50. Sunflower seeds can slide down the surface of the air guide shell 65 into the receiving trough 71. Preferably, a screen 711 is provided in the receiving trough 71. Impurities falling into the receiving trough 71 along with the sunflower seeds can fall to the bottom of the trough through the mesh of the screen 711, while the sunflower seeds are intercepted on the screen 711. Preferably, one side of the bottom of the receiving trough 71 has a side opening 712 for pouring out impurities. Preferably, the receiving trough 71 can be detachably assembled with the frame 90 by magnetic attraction, thus facilitating the removal of the receiving trough 71.

[0070] Preferably, a baffle plate 66 is arranged diagonally above the air guide shell 65. The baffle plate 66 is used to block the airflow to prevent the airflow from interfering with the processing of sunflower seeds 1000 by the upstream related components.

[0071] In some preferred embodiments, the distance between the two drive rollers 412 at the lower ends of the two pressure components 41 is correlated with the rotational speed of the fan 62 of the blower mechanism 60. Specifically, the position of the drive roller 412 of one of the pressure components 41 is mechanically adjusted by turning the knob 61, thereby adjusting the distance between the two drive rollers 412. At the same time, the rotational speed of the fan 62 is electrically adjusted by driving the driven disk 64, which is driven by the active disk 63 that rotates synchronously with the knob 61. The relationship between the rotational speed of the fan 62 and the distance between the two drive rollers 412 is that the greater the distance between the two drive rollers 412, the greater the rotational speed of the fan 62. In this way, the distance of the drive rollers 412 is adjusted to process sunflower seeds 1000 of different sizes. The fan 62 adjusts the airflow based on the different sizes of sunflower seeds 1000 so that the kernels and shells of the sunflower seeds are always separated and collected by the corresponding collection trough 71 and waste trough 72.

[0072] Preferably, the driven component described above can be powered by a single motor 73, and the rotational speed ratio between the drive roller 412, the force roller 51, and the conveying roller 23 can be achieved by configuring a gear set.

[0073] In some preferred embodiments, the device provided by the present invention is also equipped with detection components such as sensors and control and alarm modules. For example, a sensor 81 is disposed on the top of the waste trough 72 to detect the height of the sunflower seed shells accumulated in the waste trough 72. If the height exceeds a set height, an alarm is triggered, and the motor 73 is controlled to stop rotating so that the user can remove the waste trough 72 and pour out the sunflower seed shells. For example, a sensor (not shown) is disposed on the top or side of the receiving trough 71 to detect the accumulation of sunflower seed kernels in the receiving trough 71. If the height exceeds the set height, an alarm will be triggered, and the motor 73 will be stopped to allow the user to unload the receiving trough 71 and pour out the sunflower seeds. For example, sensors 82 are arranged on the walls of each guiding channel 33 of the guiding component 30 to detect whether there are sunflower seeds 1000 that have been stuck in the guiding channel 33 for a long time without falling. If so, it means that the sunflower seeds 1000 are stuck in the guiding channel 33, and the machine will stop and an alarm will be triggered to inform the user that there are sunflower seeds 1000 stuck in the guiding channel 33 and the obstruction needs to be removed.

Claims

1. A peeling mechanism, characterized in that, include: The skin-tapping mechanism includes two pressure-applying components arranged opposite to each other. Each pressure-applying component includes a support body with drive rollers arranged at both ends and a pressure belt sleeved on the support body and driven by the drive rollers; wherein: V-shaped grooves with V-shaped cross-sections extending along the length direction are respectively configured at opposite positions of the two pressure belts. The two opposing V-shaped grooves of the two pressure belts form a set to define the extrusion chamber. By arranging the two pressure components at an angle relative to each other, the extrusion chamber is reduced in the conveying direction of the pressure belt by bringing the two V-shaped grooves closer to each other. This forces the two outer shells of the sunflower seed, which enter the extrusion chamber with their two side edges facing the apex angles of the two V-shaped grooves and are driven by the pressure belt, to separate the sunflower seed kernel from the skin formed by the two outer shells.

2. The peeling mechanism according to claim 1, characterized in that, The pressure band is provided with toothed ribs arranged at intervals along its length. The toothed ribs on two pressure bands are used to enter the tooth gap between each other's toothed ribs. The V-shaped groove is formed on the toothed ribs and passes through the toothed ribs.

3. The peeling mechanism according to claim 1, characterized in that, The peeling mechanism further includes an auxiliary separation mechanism, which is located downstream of the peeling mechanism and is used to receive the sunflower seeds after they have been processed by the peeling mechanism; wherein: The auxiliary separation mechanism includes two parallel force-applying rollers, each of which has an elastic friction layer on its surface. Two force rollers are configured to rotate in opposite directions with a speed difference, in order to separate the sunflower seed kernels from their skins as they pass between the two force rollers.
