Description

Technical Field

[0001] The invention relates to longan processing equipment, and more particularly to a longan automatic shelling and core removing machine. Background Art

[0002] As a tropical / subtropical fruit, longan is mainly composed of shell, pulp and kernel. The pulp of longan is fresh and juicy, with a particularly good taste, and is widely loved by the public. Moreover, longan can also be processed into dried longan pulp. Dried longan pulp is used as a soup ingredient to replenish qi and blood and relieve fatigue. When processing fresh longan fruit, it is necessary to perform shelling-de-fleshing-core removal operations. In the existing automatic shelling and core removal machines for longan, the mainstream is to use multiple knives to realize the shelling of longan, and then blow out the longan kernel from it through high-pressure gas to achieve the separation of the three. Then, when the shell is opened, the existing technology only cuts the periphery and top of the longan shell, and the cutting position is fixed. This method easily causes the situation that the cut shell parts of the longan are adhered and not completely broken, and the shell is still on the pulp. In the process of blowing the core, the problem of the flesh connecting the core and being blown away together often occurs.

[0039] The present invention will be further described below in conjunction with the embodiments, but it does not constitute any limitation to the present invention. Any limited number of modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0040] See also Figure 1-Figure 17The invention discloses an automatic longan shelling and core removing machine, comprising a main frame 1, a longan shelling device 2 and a longan flesh remover 4. A fruit storage bucket 8 is installed on one side of the main frame 1, and the longan shelling device 2 is rotatably installed in the main frame 1 on one side of the fruit storage bucket 8. A joint fruit loading structure is provided between the fruit storage bucket 8, the longan shelling device 2 and the main frame 1, and a shell breaking and shelling track group connected to the longan shelling device 2 is installed in the main frame 1; the longan flesh remover 4 is rotatably installed in the main frame 1 on one side of the longan shelling device 2, and a fleshing track 5 connected to the longan flesh remover 4 is installed in the main frame 1; and a core remover 9 is installed on the other side of the main frame 1. During operation, the combined fruit loading structure loads the longan 3 in the fruit storage bucket 8 into the longan shelling device 2, and the longan 3 in the fixed fruit cup 25 is shelled and opened by the fruit breaking knife 28 and the shell opening swinging hand 23 arranged therein, and then the core of the shelled longan 3 is taken out together with the flesh through the longan flesh remover 4, and the flesh is removed from the core; finally, the core on the longan flesh remover 4 is frictionally rotated by the core remover 9 to make it fall off the core drilling needle 42, thereby realizing the processing process of the longan 3, and obtaining the shell, flesh and shell respectively, and the three processes are clear and separated thoroughly, the shell, flesh and core will not be mixed with each other, and there is no need for secondary sorting, which greatly improves the processing efficiency of the longan.

[0041] The following will give a detailed introduction to each component of the longan automatic shelling and core removing machine.

[0042] like Figure 4 and Fig.10 As shown, the combined fruit loading structure includes an upper fruit cup 30, a material baffle plate 19, a blocking knife 32 and a fruit picking steel bar 191. The material baffle plate 19 is installed on one side of the fruit storage bucket 8, the upper fruit cup 30 is fixed on the supporting bracket 26, a through slot 80 matching the upper fruit cup 30 is provided in the fruit storage bucket 8, a clearance slot 190 is provided in the material baffle plate 19, the blocking knife 32 is installed on the connecting frame 27, and the moving path of the blocking knife 32 is consistent with the path of the through slot 80; the fruit picking steel bar 191 is installed on the top of the material baffle plate 19, and the fruit picking steel bar 191 has a bending interference portion extending above the moving path of the upper fruit cup 30. Among them, the diameter of the upper fruit cup 30 is smaller than the average diameter of the longan, so as to avoid the problem of longan falling due to the excessive size of the through slot 80.

[0043] When the upper fruit cup 30 passes through the slot 80 from below the fruit storage bucket 8 and enters and passes through the fruit storage bucket 8, the upper fruit cup 30 will carry a longan 3 and rotate and move upward along with the longan shell opening device 2. When passing through the baffle plate 19, the upper fruit cup 30 is located on the outside of the upper fruit cup 30, a part of the supporting bracket 26 passes through the clearance slot 190, and the blocking knife 32 is in the middle of the clearance slot 190 to block the longan to prevent the longan from being stuck in the clearance slot 190 and moving with the upper fruit cup 30. When the upper fruit cup 30 moves to the end of the baffle plate 19 and enters the interference area of ​​the fruit picking steel bar 191, under the action of the bent interference portion, the longan in the upper fruit cup 30 will fall toward the fixed fruit cup 25 and fall into the fixed fruit cup 25, so as to achieve fruit placement.

[0044] The structure of the longan shell opening device 2 is as follows: Figure 4-Figure 9 As shown, it includes a fixed seat 20, a guide seat 21, a clamping swing hand 24, and a shell opening swing hand 23. The fixed seat 20 is rotatably installed in the main frame 1 through a rotating shaft 100. When the rotating shaft 100 rotates, the fixed seat 20 can be driven to rotate. A central guide column 22 is installed in the fixed seat 20, and a fruit fixing cup 25 is installed on the top of the central guide column 22. In this embodiment, the fruit fixing cup 25 is connected to the central guide column 22 through an elastic mechanism to achieve an elastic design of the fruit fixing cup 25. The center position of the longan 3 is automatically adjusted by the different downward pressures of the fruit fixing cup 25 by the longan 3, so that the center positions of longans of different sizes are basically located on the same horizontal plane, which not only reduces the gap between the longan and the fruit breaking knife 28 when breaking the shell, thereby reducing the amount of cutting into the longan pulp when breaking the shell, but also facilitates the drilling needle 42 to drill into the fruit core.

[0045] Specifically, Figure 7 and Figure 8 As shown, the elastic mechanism includes an insertion rod 251, a spring 252 and a positioning sleeve 253. One end of the insertion rod 251 is fixedly connected to the fixed fruit cup 25, and the other end of the insertion rod 251 is movably inserted into the top of the central guide column 22 and is slidably connected to the central guide column 22, which can effectively prevent the rotation of the insertion rod 251. The positioning sleeve 253 is fixed to the top of the central guide column 22, the spring 252 is arranged above the central guide column 22, and the spring 252 is sleeved on the insertion rod 251, thereby realizing the elastic installation of the fixed fruit cup 25.

[0046] The guide seat 21 is slidably installed in the central guide column 22, and the clamping swing hand 24 and the shell opening swing hand 23 are both hinged on the fixed seat 20, and the clamping swing hand 24 and the shell opening swing hand 23 pass through the guide seat 21 at the same time. A tension spring 29 is provided between the guide seat 21 and the fixed seat 20. Among them, there are two clamping swing hands 24 and two shell opening swing hands 23, and the two clamping swing hands 24 are symmetrically arranged, and the two shell opening swing hands 23 are also symmetrically arranged. When the guide seat 21 moves up, the clamping swing hands 24 and the shell opening swing hands 23 are simultaneously retracted toward the central guide column 22, and the two clamping swing hands 24 clamp the longan 3, and the two shell opening swing hands 23 are used to open the shell of the longan 3 after the shell is broken.

[0047] Specifically, Figure 6 As shown, the shell opening swing handle 23 includes a connecting rod 230, a shell opening pull head 231 and a pull head shaft 234. The connecting rod 230 is hingedly mounted on the fixed seat 20, and the connecting rod 230 passes through the guide seat 21. More specifically, as Fig. 9 As shown, a through hole 210 is provided on the guide seat 21, and semicircular protrusions 211 are provided on opposite sides of the through hole 210, and a gap 212 matching the connecting rod 230 is provided between the two semicircular protrusions 211, and the connecting rod 230 is inserted in the gap 212. When the guide seat 21 is at the lowest position, the connecting rod 230 is tilted outward, and when the guide seat 21 moves upward, since the distance between the gap 212 and the central guide column 22 remains unchanged, the connecting rod 230 moves toward the central guide column 22, and the two shell swinging hands 23 are in a retracted state. The shell opening pull head 231 is rotatably installed at the end of the connecting rod 230, and a connecting piece 232 is installed on the shell opening pull head 231. The end of the connecting piece 232 is provided with a shell opening hook 233, and the shell opening hook 233 is located above the fixed fruit cup 25. A torsion spring 237 is installed at the connection between the shell opening pull head 231 and the connecting rod 230, one end of the torsion spring 237 is installed on the connecting rod 230, and the other end of the torsion spring 237 is installed on the shell opening pull head 231, and the pull head shaft 234 is installed on one side of the shell opening pull head 231.

[0048] like Figure 6As shown, the clamping swing arm 24 includes a second connecting rod 240 and a steel sheet 1 241. The second connecting rod 240 is hingedly mounted on the fixed seat 20, and the second connecting rod 240 passes through the guide seat 21. More specifically, a second through hole 213 is provided on the guide seat 21, and two semicircular protrusions 214 are provided on opposite sides of the second through hole 213. A second gap 215 matching the second connecting rod 240 is provided in the two semicircular protrusions 214, and the second connecting rod 240 is inserted in the second gap 215. The action state of the second connecting rod 240 is consistent with that of the first connecting rod 230, that is, when the guide seat 21 is located at the lowest position, the second connecting rod 240 is tilted outward, and when the guide seat 21 moves upward, the second connecting rod 240 moves toward the center guide column 22, and the two clamping swing arms 24 form a retracted state. The steel sheet 1 241 is installed at the end of the connecting rod 240 , and the steel sheet 1 241 extends to the outside of the fixed fruit cup 25 . A sawtooth bar 242 is fixedly provided at the end of the steel sheet 1 241 , and a notch 250 is provided at a position of the fixed fruit cup 25 corresponding to the sawtooth bar 242 .

[0049] Although the clamping swing hand 24 can clamp the longan, the clamping force is limited. When the fruit-breaking knife presses down to break the shell, the longan will still be pressed and move downward. To solve this problem, Figure 8 As shown, in this embodiment, a plurality of evenly arranged stop grooves 257 are provided on the side wall of the insertion rod 251, a cutting groove 254 is provided on the positioning sleeve 253, a V-shaped plug-in 255 is rotatably installed in the cutting groove 254, the V-shaped plug-in 255 is provided with an insertion end matching the stop groove 257, a buckle 256 is installed on the side of the V-shaped plug-in 255 away from the center guide column 22, a steel sheet 236 is installed on one of the shell opening swing hands 23, and the end of the steel sheet 236 is inserted into the buckle 256. In the process of the connecting frame 27 driving the fruit breaking knife 28 to rotate and press down, the upward movement of the guide seat 21 also drives the connecting rod 1 230 to rotate toward the center guide column 22, and the rotation of the connecting rod 1 230 will make the steel sheet 2 236 closer and closer to the center guide column 22, thereby causing the V-shaped plug-in 255 to rotate, and its insertion end will move toward the insertion rod 251 and finally be inserted into the stop groove 257, thereby stopping the insertion rod 251, effectively avoiding the problem of the longan being pressed and causing the fruit cup 25 to move downward.

[0050] A bearing bracket 26 is mounted on the fixed seat 20, and the bearing bracket 26 is mounted on the fixed seat 20. A connecting frame 27 is rotatably mounted on the supporting bracket 26, and a torsion spring 2 is arranged between the connecting frame 27 and the supporting bracket 26, so that the connecting frame 27 can automatically reset after rotating; a stop bar is arranged on one side of the upper fruit cup 30 on the supporting bracket 26, and the stop bar blocks the side of the connecting frame 27 away from the fixed fruit cup 25, so as to block and position the connecting frame 27 in a vertical direction, and a fruit breaking knife 28 with a blade facing the fixed fruit cup 25 is installed on one side of the connecting frame 27. A push rod 216 is fixed on the outer side of the guide seat 21, and the connecting frame 27, the push rod 216 and the pull head shaft rod 234 are connected to the shell breaking and opening track group. The setting of the shell breaking and shell opening track group mainly utilizes the contact between the connecting frame 27, the push rod 216 and the pulling head shaft 234 and the corresponding tracks when the longan shell opening device 2 rotates to realize the shell breaking and shell opening process. There is no need to additionally set up an electric drive to drive the movement of the fruit breaking knife 28, the guide seat 21 and the shell opening pulling head 231, which plays a role in reducing the cost and complexity of the whole machine.

[0051] Specifically, Figure 10-12 As shown, the shell breaking and shell opening track group includes a fruit breaking track 102, a hand-waving and closing track 103 and a shell opening track 105. Among them, the fruit breaking track 102 is arranged above the main frame 1, and the connecting frame 27 is provided with a track portion 31 that can move along the inner side of the fruit breaking track 102. More specifically, the track portion 31 is a bearing installed at the end of the connecting frame 27. The fruit breaking track 102 is provided with a track changing section 1020 and a pressing section 1021. Among them, the track changing section 1020 is a twisted track that drives the connecting frame 27 and the fruit breaking knife 28 to rotate toward the fixed fruit cup 25, and the pressing section 1021 is an arc track that drives the connecting frame 27 and the fruit breaking knife 28 to press down the longan 3 to break the shell, and the difference in the arc radius at both ends of the arc is designed based on the thickness of the longan shell, and is generally designed to be equal to the average thickness of the longan shell, which is conducive to shell breaking.

[0052] The swinging hand and retracting track 103 is arranged around the rotating axis of the longan shell opening device 2, and a bearing is installed on the push rod 216, which is in contact with the outer side of the swinging hand and retracting track 103. A protrusion 104 is provided on the side of the swinging hand and retracting track 103 close to the longan flesh remover 4, so that when the bearing on the push rod 216 moves into the protrusion 104, the guide seat 21 moves toward the fixed fruit cup 25, thereby causing the clamping swing hand 24 and the shell opening swing hand 23 to be retracted.

[0053] The shell opening track 105 is arranged around the rotating axis of the longan shell opening device 2, and a bearing is installed at the end of the pull head shaft 234, which contacts the inner side of the shell opening track 105. A recess 106 is provided on the side of the shell opening track 105 close to the longan flesh remover 4, so that when the bearing on the pull head shaft 234 moves into the recess 106, it forms a downward pressure on the pull head shaft 234, thereby causing the shell opening hook 233 to rotate toward the fixed fruit cup 25 and finally enter the shell breaking position.

[0054] The relationship between the above three tracks lies in that the projection of the downward pressure section 1021 is located within the projection of the raised portion 104; the horizontal positions of the stop point 107 in the raised portion 104 away from one end of the fruit breaking track 102 and the stop point 2 108 in the recessed portion 106 away from one end of the fruit breaking track 102 are adapted to the horizontal positions of the longan shelling device 2 and the longan fleshing device 4 when they are closest to each other, and can be specifically set to be at the same horizontal position.

[0055] With such arrangement, during the process of the longan shell opening device 2 breaking and opening the shell of the longan 3, the working process is as follows:

[0056] The bearing on the connecting frame 27 first contacts the track changing section 1020, and causes the connecting frame 27 and the fruit breaking knife 28 to rotate toward the fixed fruit cup 25; as the longan shell opening device 2 continues to rotate, the bearing on the push rod 1 216 will enter the raised portion 104 of the swinging hand retracting track 103, so that the clamping swinging hand 24 and the shell opening swinging hand 23 are retracted; then, the bearing on the connecting frame 27 enters the pressing section 1021, so that the fruit breaking knife 28 presses down the longan in the fixed fruit cup 25 to break the fruit. After the bearing on the connecting frame 27 has finished walking on the pressing section 1021, the fruit breaking action is completed, and the connecting frame 27 and the fruit breaking knife are reset, and then the bearing on the pull head shaft rod 234 will enter the recessed portion 106, so that the pull head shaft rod 234 is pressed down, thereby driving the shell opening hook 233 to rotate toward the fixed fruit cup 25, and finally enter the shell breaking position.

[0057] like Fig.13As shown, the longan flesh remover 4 includes a seat body 1 40 and a seat body 2 41. The seat body 1 40 is rotatably mounted in the main frame 1 via a rotating shaft 2 101. A fruit core drilling needle 42 is movably arranged in the seat body 1 40. The two ends of the fruit core drilling needle 42 respectively penetrate and extend to the outside of the seat body 1 40. A driving wheel 50 is arranged at one end of the fruit core drilling needle 42. A driving disk 6 is rotatably mounted on the rotating shaft 2 101. The driving disk 6 is in frictional contact with the driving wheel 50 to achieve a transmission connection between the two. The seat body 2 41 is fixed to one side of the seat body 1 40. A push rod 2 45 is slidably mounted in the seat body 2 41. A connecting seat 46 is mounted at one end of the push rod 2 45 near the tail of the fruit core drilling needle 42. A flesh remover 47 extending to the periphery of the tail of the fruit core drilling needle 42 is mounted on the connecting seat 46. A push rod bearing 49 is fixed on the push rod 2 45. The push rod bearing 49 contacts the outer side of the flesh remover track 5. Among them, the flesh removal track 5 is provided with a convex point 501, and the convex point 501 is located below the rotating shaft 101. When the push rod bearing 49 enters the convex point 501 area, the flesh removal knife 47 will move forward, thereby removing the flesh of the shelled longan on the core drilling needle 42, leaving the shell on the core drilling needle 42, and realizing the separation of the flesh and shell.

[0058] The end of the core drilling needle 42 of this embodiment is a needle tail 43, and a threaded core drilling section 44 is provided at the end of the needle tail 43, which is used to drill into the core of the shelled longan to fix the core. When the fleshing knife 47 is used for fleshing, the flesh can be easily removed without the core falling off, achieving a better separation effect, which is practical and reliable. In addition, a fleshing spring 48 is installed on the connecting seat 46, and the fleshing spring 48 bypasses the fleshing knife 47 and extends along the needle tail 43 toward the threaded core drilling section 44. The fleshing spring 48 can be attached to the needle tail 43. When the push rod 45 pushes the fleshing knife 47 and the fleshing spring 48 to move toward the threaded drill core section 44, the fleshing spring 48 has good deformation characteristics and the longan flesh is soft and tender, so it will move along the needle tail 43 and pass through the flesh to the core. The core is hard and its surface is smooth, so the fleshing spring 48 will move along the surface of the core, thereby forming a separation effect on the flesh, which is very beneficial to the fleshing of longan.

[0059] The automatic longan shelling and core removing machine of the present invention adopts a single motor driving mechanism to drive the longan shelling device 2 and the longan fleshing device 4. Figure 3As shown, a driver 120 is installed on the main frame 1, which is composed of a motor 2 and a reduction box. The reduction box is provided with two drive output ends, and a gear 122 with the same size and specification is installed on the rotating shaft 100 and the rotating shaft 2 101, and the two gears 122 are meshed. A main drive tooth 121 is provided on a drive output end of the driver 120, and the main drive tooth 121 is meshed and connected with a gear 122 near it. The drive disc 6 is rotatably connected with the rotating shaft 2 101 through the connecting shaft 7, and the other drive output end of the driver 120 is transmission-connected with the connecting shaft 7 through a belt transmission mechanism 123. In addition, a control panel 14 is also provided on the main frame 1 near the driver 120, which is used to control the actions of various drive components in the automatic longan shelling and core removing machine, such as the switch and speed regulation of the motor.

[0060] like Fig.14 As shown, the core remover 9 includes a motor 91, a core removal turntable 92 and a protective cover 93. The motor 91 and the protective cover 93 are both mounted on the main frame 1, the core removal turntable 92 is mounted on the driving end of the motor 91, and the core removal turntable 92 is located in the protective cover 93. The core removal turntable 92 is arranged in an inclined shape relative to the rotation plane of the longan flesh remover 4, which is conducive to contact with the fruit core, making the fruit core easier to fall off by friction, and at the same time can form a barrier to the fruit core to prevent it from flying out of the protective cover 93. Among them, the rotation direction of the core removal turntable 92 is opposite to the rotation direction of the fruit core drilling needle 42. A core outlet flow channel 94 is installed on one side of the protective cover 93. In order to increase the friction between the core removal turntable 92 and the fruit core, a stamping method can be used to form a bulge on the side of the core removal turntable 92 that contacts the fruit core.

[0061] like Fig.15 and Fig.16As shown, in order to facilitate the collection of shells, pulp and cores, a collecting channel 171 is provided below the longan shell opening device 2, and a sorter 172 is provided below the bottom of the collecting channel 171. A shell outlet channel 174 is provided on one side of the sorter 172, and a flesh outlet channel 173 is provided on the other side of the sorter 172. During the shell opening process, if there is a situation where the pulp is hooked by the shell opening hook 233, it will fall into the collecting channel 171 and slide into the sorter 172 through the collecting channel 171. The sorter 172 is composed of a plurality of row pins 1721 hingedly mounted in the main frame 1, and all the row pins 1721 are on the same horizontal plane, and the row pins 1721 are tilted downward, with one end being longer and the other end being lower, the longer end drooping, and the lower end being equipped with a counterweight 1722. Taking advantage of the fact that the fruit shell is lighter than the fruit flesh, both the fruit flesh and the fruit shell fall on the longer end of the row needle 1721. When the fruit flesh falls, the longer end of the row needle 1721 cannot support the fruit flesh, so it rotates greatly, and the fruit flesh will fall into the meat outlet flow channel 173 below it; when the fruit shell falls, the longer end of the row needle 1721 can support the fruit flesh without rotating greatly, and the fruit flesh will slide along the row needle 1721 into the shell outlet flow channel 174 on one side. A collection bucket can be placed under the meat outlet flow channel 173 and the shell outlet flow channel 174 to collect them.

[0062] like Fig.17 As shown, a second collecting channel 181 is provided below the longan pulp remover 4, and a second meat outlet channel 182 is provided on one side of the bottom of the second collecting channel 181, and a longan pulp collector 15 is provided below the second meat outlet channel 182 for collecting longan pulp. The second collecting channel 181 serves as the main outlet channel for longan pulp, and the longan pulp collector 15 is arranged below the second meat outlet channel 182, wherein a rotating table is provided, and the rotating table is used to place a collecting tray 16, such as a dustpan. When the rotating table drives the collecting tray 16 to rotate, the pulp will be more evenly scattered in the collecting tray 16, thereby preventing the pulp from accumulating at one position of the collecting tray 16.

[0063] A fruit storage box 10 connected to the fruit storage bucket 8 is hung on one side of the main frame 1 of the present embodiment, so that more longans can be stored in advance without frequent loading. A water tank 11 is provided in the main frame 1, and a water pump is installed in the water tank 11. A water spray head for spraying and cleaning the parts that are easy to adhere to the juice is installed on the main frame 1, such as a fruit core needle 42 and a meat removal knife 47. When the longan meat removal device 4 moves below the plane where its axis is located and passes through the convex point 501, the water pump can be started to spray water to clean the fruit core needle 42 and the meat removal knife 47. In order to prevent water from flowing into the meat outlet flow channel 182, the bottom of the collection flow channel 181 can adopt a grid design so that the cleaned water flows directly out of the grid holes. A water receiving tray can also be placed below the main frame 1 to collect the cleaning water and juice.

[0064] The working principle of the present invention is:

[0065] Loading stage: The longan shelling device 2 rotates around the rotating shaft 100 under the driving action of the driver 120. When the longan shelling device 2 carries the upper fruit cup 30 from the bottom of the fruit storage bucket 8 through the slot 80 and enters and passes through the fruit storage bucket 8, the upper fruit cup 30 will carry a longan 3 and rotate upward along with the longan shelling device 2. Fig.10 When the upper fruit cup 30 moves to the end of the baffle plate 19 and enters the interference area of ​​the fruit picking steel bar 191, under the action of the bending interference portion, the longan in the upper fruit cup 30 will fall toward the fixed fruit cup 25 and fall into the fixed fruit cup 25.

[0066] Shell breaking stage: as the longan shell opening device 2 rotates, the bearing on the connecting frame 27 first contacts the track changing section 1020, and causes the connecting frame 27 and the fruit breaking knife 28 to rotate toward the fixed fruit cup 25; as the longan shell opening device 2 continues to rotate, the bearing on the push rod 1 216 will enter the raised portion 104 of the swing hand retracting track 103, thereby causing the clamping swing hand 24 and the shell opening swing hand 23 to retract; then, the bearing on the connecting frame 27 enters the pressing section 1021, causing the fruit breaking knife 28 to press down the longan in the fixed fruit cup 25 to break the fruit, as shown in FIG. Fig.11 When the fruit breaking action is completed and the connecting frame 27 and the fruit breaking knife are reset, the bearing on the pull head shaft 234 will enter the recessed portion 106, so that the pull head shaft 234 is pressed down, thereby driving the shell opening hook 233 to rotate toward the fruit fixing cup 25 and finally enter the shell breaking position.

[0067] The stage of the core drilling needle 42 drilling into the core: when the fruit cup 25 moves to the plane above the rotating shaft 100 and the rotating shaft 2 101, the longan peeling device 4 also rotates to the corresponding position opposite to it. As the rotating shaft rotates, the core drilling needle 42 on the longan peeling device 4 and the longan 3 in the fruit cup 25 approach each other, contact each other, and drill into each other. Finally, when the fruit cup 25, the core drilling needle 42 and the two rotating shafts are all in the same plane, the threaded core drilling section 44 will drill into the longan 3, as shown in FIG. Fig.12 shown.

[0068] Shelling and meat taking stage: When the longan shelling device 2 and the longan fleshing device 4 rotate toward the bottom of the main frame 1 through the above-mentioned plane, the ends of the two are separated by the closest position. Among them, in the longan shelling device 2, the bearing of the push rod 1 216 and the bearing of the pull head shaft rod 234 pass through the stop points of the protrusion 104 and the recessed portion 106 respectively, that is, the push rod 1 216 leaves the protrusion 104, and the pull head shaft rod 234 leaves the recessed portion 106, and resets along the corresponding track under the action of the corresponding spring, so that the shelling hooks 233 on the two shelling swinging hands 23 rotate away from the fixed fruit cup 25, and the entire shelling swinging hands 23 rotate away from the center guide column 22, thereby realizing the shelling hook 233 pulling the shell apart. In the longan fleshing device 4, since the distance between the shelled longan 3 on the threaded drill core section 44 and the rotating shaft 2 101 remains unchanged, the shelled longan 3 will be taken out from the shell.

[0069] Fleshing stage: As the flesh remover 4 continues to rotate, when the push rod bearing 49 moves to the convex point 501 on the flesh removal track 5, the push rod 45 and the connecting seat 46, the flesh removal knife 47, and the flesh removal spring 48 all move toward the threaded core section 44. The flesh removal spring 48 is first inserted into the flesh, and then moves along the smooth surface of the core, and then the flesh removal knife 47 is also inserted into the flesh, and when the insertion resistance is greater than the force of the flesh to be detached from the core, the flesh will be removed from the core, and the flesh and core separation is achieved.

[0070] Core removal stage: When the eye peeler 4 rotates to the side of the core remover 9, the fruit core on the threaded core drill section 44 will come into friction contact with the core removal turntable 92 of the core remover 9, and the opposite rotation of the two can effectively cause the fruit core to fall off from the threaded core drill section 44 by friction.

[0071] In order to improve the efficiency of the whole machine, multiple longan shell opening devices 2 and longan fleshing devices 4 can be used in combination. Multiple longan shell opening devices 2 and longan fleshing devices 4 are evenly installed on the corresponding rotating shafts of the longan shell opening devices 2 and the longan fleshing devices 4. Fig.18 In the embodiment, three longan shell opening devices 2 and longan flesh removing devices 4 are arranged on the corresponding rotating shafts, but the number is not limited to three, and can also be arranged as 2 or more than 3. In this way, the production efficiency can be greatly improved.

[0072] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
