Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of nut processing equipment, and in particular relates to a shelling device for pecan processing. Background Art
[0002] Pecans are also known as thin-shell pecans. Pecans are shaped like large olives, with plenty of flesh and fragrance. They are one of the world's top ten nuts. Pecans are long oval-shaped dried fruits, and their kernels have excellent therapeutic and health value. High-quality pecans have very thin peels that can be peeled by hand, and the taste of the kernels is between the pecans and walnuts we often eat. As a snack, pecans are mainly edible kernels, with a hard shell on the outside and a layer of shell on the outside.
[0003] The outer shell of pecans is green and oval before maturity. When mature, the shell turns black and the edges naturally crack into four petals. The core is removed from the shell, which consists of a seed shell and a kernel. The main process is to remove the shell and then process the core to increase its edible value through frying, drying, and cracking. Removing the shell is the most complicated part. The ripe fruit is dried and then rolled to make the shell naturally crack along its own cracks, splitting into four even petals. A single petal shell is only about half the size of the core.
[0004] The invention mainly prepares a pecan shelling device, which squeezes the dried fruit by kneading so that the dried fruit shells automatically crack along the gaps, and automatically screens the cracked shells and kernels according to the size difference. Summary of the invention
[0005] The object of the present invention is to provide a pecan peeling device for processing pecans, which squeezes the dried fruit by kneading so that the dried fruit shells automatically crack along the gaps, and automatically screens the cracked shells and kernels according to their sizes.
[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The shelling device for pecan processing comprises a shell, which is a square shell structure, with a feeding bin at the end, a processing bin in the middle, and a discharging bin at the tail, and the shell comprises side plates at left and right sides, a front side plate, a rear side plate, a top plate, and a bottom plate; A plurality of support rods are arranged in the horizontal direction at the middle position of the shell, and the ends of the support rods pass through the front side plate and the rear side plate respectively, and are rotatably matched with the corresponding passing parts, and the plurality of support rods are evenly and equidistantly arranged to form a horizontal support surface; The portion of the support rod passing through the front side plate is sleeved with a first gear, the housing is equipped with a first motor, the output end of the first motor is equipped with a second gear, and the second gear drives multiple first gears to rotate in the same direction simultaneously through a toothed chain; The outer wall of the support rod corresponding to the feeding bin and the processing bin has spiral ribs; The processing chamber includes a kneading plate located on the upper side of the support rod, and the kneading plate is a horizontal plate structure and is arranged parallel to the support surface formed by the support rod; The top plate is provided with a driving device for driving the kneading plate to move back and forth left and right.
[0007] Furthermore, the kneading plate is provided with strip-shaped ribs in the gaps between the adjacent support rods, the strip-shaped ribs are arranged at intervals from the support rods, and the cross-section of the strip-shaped ribs is semicircular.
[0008] Furthermore, a positioning plate is installed on the upper side of the kneading plate, and a interlayer is provided between the positioning plate and the upper side of the kneading plate. A first spring is installed in the interlayer between the positioning plate and the kneading plate, and the first spring is distributed at a position corresponding to the corner of the kneading plate. The first spring is sleeved with a positioning rod, and the lower end of the positioning rod is fixed to the upper side of the kneading plate, and the upper end passes through the positioning plate and is telescopically matched with the passing part of the positioning plate. A positioning block is provided on the part of the positioning rod passing through the positioning plate.
[0009] The side of the kneading plate has a first side wall, which is perpendicular to the side of the kneading plate. The positioning plate has a second side wall sleeved with the first side wall, which is perpendicular to the side of the positioning plate.
[0010] The second side walls on both sides corresponding to the positioning plate are provided with column sleeves, and guide columns are connected between the side plates on both sides, the guide columns correspond to the column sleeves, and the column sleeves are slidably engaged. A second spring is installed between the column sleeves and the corresponding side plates, and the second spring is sleeved with the guide column.
[0011] Furthermore, the driving device includes a second motor installed on the top plate, a crankshaft is installed on the output end of the second motor, an articulated shaft is fixed on the upper side of the positioning plate, a connecting rod is connected between the crankshaft and the articulated shaft, and both ends of the connecting rod are hingedly installed with the crankshaft and the articulated shaft.
[0012] Furthermore, a discharge plate is installed on the upper edge of the rear side plate, and the discharge plate is arranged obliquely; a feeding plate is fixed at a position of the feeding bin corresponding to the front side plate, and the feeding plate is arranged obliquely.
[0013] Furthermore, the feeding bin is separated from the processing bin by a guide plate, the left and right sides of the guide plate are fixed to the side plates on both sides, and the guide plate has an arc-shaped portion at the upper position corresponding to the support rod, which is used to limit a single fruit from entering the processing bin.
[0014] The present invention has the following beneficial effects: the feeding bin and the processing bin are connected parts, and share the support surface formed by the same support rods. After the fruit is added to the feeding bin, it falls on the support surface formed by the support rods and is evenly distributed. As the support rods rotate, the fruit automatically fits into the gap between adjacent support rods. As the support rods rotate and cooperate with the driving action of the spiral ribs, the fruit moves unidirectionally to the processing bin part. The kneading plates corresponding to the processing bin press and knead the fruit shells corresponding to the fruit to crack along their own cracks. As the kneading process is repeated many times, the cracked fruit shells become small pieces with a diameter smaller than the gap between the support rods, and pass through the gap between the support rods to fall onto the bottom plate.
[0015] However, the core part still remains on the supporting surface formed by the support rod because its width is greater than the gap of the support rod. At the same time, the seed shell is hard and will not be affected by the kneading plate. With the continuous rotation of the support rod, the core part that has been processed and shelled is finally guided out from the rear side plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0027] like Figure 1-3 As shown: a pecan peeling device for processing pecans includes an outer shell, which is a square shell structure, with a feeding bin at the end, a processing bin in the middle, and a discharging bin at the tail. The outer shell includes side panels 12 on the left and right sides, a front side panel 11, a rear side panel 15, a top panel 13, and a bottom panel 14; the feeding bin corresponds to the front side panel 11, and the opening side of the outer shell is between the upper side of the front side panel 11 and the top panel 13, which serves as a feeding port of the feeding bin.
[0028] A plurality of support rods 2 are arranged in the horizontal direction in the middle of the shell, and the ends of the support rods 2 pass through the front side plate 11 and the rear side plate 15 respectively, and are rotated to fit the corresponding passing parts. The plurality of support rods are evenly and equidistantly arranged to form a horizontal support surface; the support rods 2 are rod bodies with circular cross-sections, and the spacing between adjacent support rods 2 is slightly larger than the width of an ordinary pecan kernel. The kernel of the pecan is similar to an elliptical structure, and the outer layer is wrapped with a fruit shell. When the fruit with the fruit shell is placed on the support rod, the fruit just fits and is stuck in the gap between the adjacent support rods 2, and the corresponding long axis of the fruit is parallel to the axis of the support rod.
[0029] like Figure 2 As shown: the part of the support rod 2 passing through the front side plate 11 is sleeved with the first gear 21, the outer shell is installed with the first motor 3, the output end of the first motor 3 is installed with the second gear 31, and the second gear 31 simultaneously drives multiple first gears 21 to rotate in the same direction through the tooth chain 32; the first motor 3 simultaneously drives multiple first gears 21 through the second gear 31, and the first gear 21 and the support rod 2 are a coaxial fixed structure, so that the multiple support rods 2 rotate axially.
[0030] The outer wall of the support rod 2 has spiral ribs 22 at the portion corresponding to the feeding bin and the processing bin; The processing chamber includes a kneading plate 4 located on the upper side of the support rod 2. The kneading plate 4 is a horizontal plate structure and is arranged parallel to the support surface formed by the support rod 2. The height of the kneading plate 4 is slightly higher than the upper support surface formed by the support rod 2, and the height is approximately equal to the diameter of a single pecan. The top plate 13 has a driving device for driving the kneading plate 4 to move back and forth. The kneading plate 4 moves back and forth at a high frequency within a small spacing range, and the small spacing does not exceed the gap distance between adjacent support rods 2. At the same time, the reciprocating kneading plate 4 provides a certain vibration effect, so that the cracked husks automatically fall through the gap between the support rods 2.
[0031] The feeding bin and the processing bin are connected parts and share the support surface formed by the same support rod 2. After the fruit is added to the feeding bin, it falls on the support surface formed by the support rod 2 and is evenly distributed. As the support rod 2 rotates, the fruit automatically gets stuck in the gap between adjacent support rods 2. As the support rod 2 rotates and cooperates with the driving action of the spiral rib 22, the fruit moves unidirectionally to the processing bin. The kneading plate 4 corresponding to the processing bin presses and kneads the fruit shell corresponding to the fruit to crack along its own cracks. As the kneading process is repeated many times, the cracked fruit shell becomes small pieces with a diameter smaller than the gap between the support rods 2, and passes through the gap between the support rods 2 and falls onto the bottom plate 14.
[0032] However, the core part, due to its width being greater than the gap of the support rod 2, still remains on the support surface formed by the support rod. At the same time, the seed shell is relatively hard and will not be affected by the kneading plate 4. With the continuous rotation of the support rod 2, the core part that has been processed and shelled is finally guided out from the rear side plate 15.
[0033] like Figure 4 As shown: the kneading plate 4 is provided with strip ribs 41 in the gaps corresponding to the adjacent support rods 2, and the strip ribs 41 are arranged at intervals with the support rods 2, and the cross section of the strip ribs 41 is semicircular. It is used to improve the kneading effect of the kneading plate 4 on the fruit. Due to the unidirectional rotation of the support rods 2, the fruit located in the gap between the support rods 2 is in a process of continuous rolling and unidirectional movement. The strip ribs 41 are just located above the gaps between the adjacent support rods 2, and the mutual squeezing of the spiral ribs 22 can improve the fracturing effect on the fruit shell.
[0034] like Figure 5As shown: a positioning plate 5 is installed on the upper side of the kneading plate 4, and there is an interlayer between the positioning plate 5 and the upper side of the kneading plate 4. A first spring 42 is installed in the interlayer between the positioning plate 5 and the kneading plate 4. The first spring 42 is distributed at the position corresponding to the corner of the kneading plate 4. The first spring 42 is sleeved with a positioning rod 41. The lower end of the positioning rod 41 is fixed to the upper side of the kneading plate 4, and the upper end passes through the positioning plate 5 and is telescopically matched with the passing part of the positioning plate 5. The part of the positioning rod 41 passing through the positioning plate 5 is provided with a positioning block 43. The positioning block 43 is used for hanging installation of the kneading plate 4. The spring structure is distributed between the positioning plate 4 and the kneading plate 5, which is used to make the kneading plate 4 elastic when pressed, and has up and down floating relative to the positioning plate 5. When the kneading plate 4 processes fruits, when the kneading plate 4 presses large-caliber fruits, the fruit core is relatively large, which can effectively prevent the kneading plate from crushing the fruit core and causing partial damage to the internal kernel.
[0035] The side of the kneading plate 4 has a first side wall 44, which is perpendicular to the side of the kneading plate 4. The positioning plate 5 has a second side wall 51 that is sleeved with the first side wall 44, and the second side wall 51 is perpendicular to the side of the positioning plate 5. The first side wall 44 and the second side wall 51 are mainly used to seal the interlayer between the positioning plate 5 and the kneading plate 4 to improve the integrity and prevent the crushed fruit shells from entering the interlayer.
[0036] like Figure 5-6 As shown: the second side walls 51 on both sides corresponding to the positioning plate 5 are provided with column sleeves 52, and guide columns 6 are connected between the side panels 12 on both sides. The guide columns 6 correspond to the column sleeves 52, and the column sleeves 52 are slidably fitted. It is used to improve the movement stability of the positioning plate 5 and the kneading plate 4 as a whole under the left and right of the driving device. The guide columns are not only used to support the kneading plate 4 and the positioning plate 5, but also provide movement guidance. A second spring 61 is installed between the column sleeve 52 and the corresponding side panel 12, and the second spring 51 is sleeved on the guide column 6. The spring is equivalent to a limit rebound to prevent the positioning plate 4 from having a rigid collision with the side panel.
[0037] like Figure 7 As shown: the driving device includes a second motor 7 mounted on the top plate 13, a crankshaft 71 is mounted on the output end of the second motor 7, a hinge shaft 53 is fixed on the upper side of the positioning plate 4, a connecting rod 72 is connected between the crankshaft 71 and the hinge shaft 53, and both ends of the connecting rod 72 are hingedly mounted to the crankshaft 71 and the hinge shaft 53. The crankshaft 71 is driven by the second motor 7, and the crankshaft 71 drives the positioning plate 5 through the connecting rod 72. Under the circular motion of the eccentric shaft corresponding to the crankshaft 71, the positioning plate 5 is driven to move back and forth.
[0038] like Figure 1 , Figure 5As shown: a discharge plate 16 is installed on the upper edge of the rear side plate 15, and the discharge plate 16 is set obliquely; a charging plate 17 is fixed at the position of the charging bin corresponding to the front side plate 11, and the charging plate 17 is set obliquely. The upper side of the charging bin is an open side, and a charging plate 17 is set to facilitate flattening after feeding, so that the fruits are automatically and evenly scattered on the upper support surface of the support rod 2. The discharge plate 16 is used to guide the fruit core after shelling, and the bottom plate 14 is used to receive the shell part that is removed.
[0039] like Figure 8 As shown: the feeding bin and the processing bin are separated by a guide plate 18, the left and right sides of the guide plate 18 are fixed to the side plates 12 on both sides, and the guide plate 18 has an arc-shaped portion corresponding to the upper side of the support rod 2, which is used to limit the position of a single fruit entering the processing bin. It is used to prevent the fruit from falling directly into the processing bin part, and guide it to between the kneading plate 4 and the support rod 2 through the guide plate 18. At the same time, it is conducive to the formation of a flattening effect of the fruit on the support surface formed by the support rod 2.
[0040] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
