Description

Technical Field

[0001] This invention relates to the field of water chestnut peeling structure design, and in particular to an automatic water chestnut peeling device for batch peeling of water chestnuts. Background Technology

[0002] Water chestnut, also known as ling, has an overall shape resembling a curved ox horn. The shell of a mature water chestnut is relatively hard, with thorns at the tips that are slender and brittle. The flesh is white, ingot-shaped, and has blunt horns. It is rich in nutrients such as potassium, phosphorus, and magnesium, as well as vitamin C, carotene, and calcium. It can be eaten raw or cooked, and has a sweet and delicious taste. It also possesses medicinal value, such as strengthening the spleen and replenishing qi.

[0003] Because the shell of a mature water chestnut is hard and contains thorns, small-batch daily consumption mainly relies on manual peeling of individual water chestnuts. After the shell is opened, the flesh is extracted, which is not only time-consuming and laborious, but also inefficient. Furthermore, there is a risk of injury from the sharp thorns during peeling, posing a certain operational hazard. Separating the flesh from the shell after opening is also difficult, especially when eating raw water chestnuts. The low efficiency of shell-meat separation often results in some flesh remaining in the shell cavity after peeling, leading to unnecessary waste. Therefore, relying solely on manual peeling of individual water chestnuts is not only inefficient but also poses safety risks. The efficiency and quality of shell-meat separation cannot be guaranteed, failing to meet the efficiency and quality requirements for large-scale water chestnut peeling. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic peeling device for water chestnuts, which improves the efficiency and safety of peeling operations for batch processing of water chestnuts, in order to address the problems existing in the prior art.

[0005] The technical problem to be solved by the present invention is achieved by the following technical solution: an automatic water chestnut peeling device, comprising a water chestnut ring-cutting mechanism and a shell-meat separation mechanism. The water chestnut ring-cutting mechanism includes a first cutter and a second cutter. The first cutter is mounted on a first ring-cutting blade holder, and the second cutter is mounted on a second ring-cutting blade holder. The blade openings of both the first and second cutters are arc-shaped, and the blade openings of the first and second cutters are positioned opposite each other. The first and second cutters move relative to each other through a blade holder driving mechanism, and the first and second cutters perform a ring-cutting action on the water chestnut during the relative closing motion. After ring-cutting, the water chestnut is peeled by the shell-meat separation mechanism.

[0006] Furthermore, the tool holder drive mechanism includes a main push rod and its drive mechanism. The main push rod forms a sliding fit structure with the first slider and the second slider respectively. The first slider forms a relatively rotating movable connection structure with one end of the first circumferential cutting link and one end of the second circumferential cutting link respectively. The other end of the first circumferential cutting link forms a movable connection structure with the circumferential cutting support. The other end of the second circumferential cutting link forms a movable connection structure with the first circumferential cutting tool holder. The second slider forms a relatively rotating movable connection structure with one end of the third circumferential cutting link and one end of the fourth circumferential cutting link respectively. The other end of the third circumferential cutting link forms a movable connection structure with the circumferential cutting support. The other end of the fourth circumferential cutting link forms a movable connection structure with the second circumferential cutting tool holder. Under the action of its drive mechanism, the main push rod moves horizontally linearly relative to the circumferential cutting support, and drives the first circumferential cutting tool holder through the first slider and the second circumferential cutting tool holder through the second slider. The first circumferential cutting tool holder drives the first cutter, and the second circumferential cutting tool holder drives the second cutter, so that the first cutter and the second cutter form a circumferential cutting action during the relative closing motion.

[0007] Furthermore, it also includes a rhombus-shaped posture correction mechanism, which includes a posture correction plate, a posture correction cam and its driving mechanism. The posture correction cam forms a relatively rotatable connection structure with one end of the posture correction connecting rod, and the other end of the posture correction connecting rod forms a relatively rotatable connection structure with the first rocker arm. The posture correction plate forms a relatively rotatable connection structure with one end of the first rocker arm and one end of the second rocker arm, respectively. The other ends of the first rocker arm and the second rocker arm respectively form a relatively rotatable connection structure with the posture correction mounting base.

[0008] Furthermore, the rhomboid posture correction mechanism also includes a flow limiting plate, which is connected to the posture correction top rod. The posture correction top rod performs reciprocating linear motion relative to the posture correction mounting base under the drive of the posture correction cam.

[0009] Furthermore, it also includes a rhombus-shaped molding mechanism, which includes a flexible wheel and its lifting drive mechanism. The flexible wheel is mounted on a flexible wheel bracket and rotates relative to the flexible wheel bracket. The flexible wheel bracket is connected to the molding guide rail via a molding connecting rod. The lifting drive mechanism of the flexible wheel includes a first cantilever, a first molding cam, and a molding drive mechanism. The first cantilever is movably connected to the molding mounting base via a first connecting shaft, and the first cantilever is connected to a first roller and a second roller respectively. The first roller and the molding guide rail form a relatively linear sliding fit structure. The first molding cam rotates relative to the molding mounting base under the action of the molding drive mechanism and drives the first cantilever through the second roller. The first cantilever drives the flexible wheel to move up and down within a certain range relative to the molding mounting base.

[0010] Furthermore, the diamond-shaped molding mechanism also includes a flexible wheel telescopic drive mechanism, which includes a second cantilever, a molding slider, and a second molding cam. The second cantilever is movably connected to the molding mounting base via a second connecting shaft, and is connected to a third roller and a fourth roller respectively. The fourth roller and the molding slider form a movable connection structure. Under the action of the molding drive mechanism, the second molding cam rotates relative to the molding mounting base and drives the second cantilever via the third roller. The second cantilever drives the flexible wheel to telescopically move relative to the molding mounting base within a certain range.

[0011] Furthermore, the shell-meat separation mechanism includes a first separation mold, a second separation mold and a mold separation drive mechanism, a first gripper and its drive mechanism, and a second gripper and its drive mechanism. The first separation mold and the second separation mold together form a rhomboid-shaped groove. Under the action of its drive mechanism, the first gripper and the second gripper simultaneously perform a clamping action relative to the rhomboid-shaped groove.

[0012] Furthermore, the mold separation driving mechanism includes a separation push plate and its driving mechanism. The two opposite ends of the separation push plate form a movable connection structure with one end of the first push rod and one end of the second push rod, respectively, which rotate relative to each other. The other end of the first push rod is connected to the first separation mold, and the other end of the second push rod is connected to the second separation mold. The separation push plate rotates under the action of its driving mechanism, driving the first separation mold through the first push rod and the second separation mold through the second push rod, until the first separation mold and the second separation mold are separated into their respective positions.

[0013] Furthermore, the driving mechanism of the first gripper includes a third electric push rod, the first separation mold is fixedly connected to one end of the first cantilever rod, the other end of the first cantilever rod forms a movable connection structure with the first gripper, the action output end of the third electric push rod forms a movable connection structure with one end of the first gripper, and the other end of the first gripper forms a clamping end.

[0014] Furthermore, the driving mechanism of the second gripper includes a second electric push rod, the second separation mold is fixedly connected to one end of the second cantilever rod, the other end of the second cantilever rod forms a movable connection structure with the second gripper, the action output end of the second electric push rod forms a movable connection structure with one end of the second gripper, and the other end of the second gripper forms a clamping end.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting the blade openings of the first and second cutters into an arc-shaped structure and positioning the blade openings of the first and second cutters opposite to each other, when the water chestnut enters the processing space formed by the first and second cutters, the blade holder drive mechanism drives the first and second cutters to form a relative closing motion. During this continuous closing motion, the first and second cutters can form a ring cutting action, which can complete the ring cutting operation of the water chestnut in one go. After the ring cutting operation, the water chestnut is then peeled by the shell and meat separation mechanism, thus completing the automatic peeling operation of the water chestnut. This completely avoids manual peeling operations, effectively avoids safety hazards such as punctures caused by the sharp points at both ends of the water chestnut, and greatly improves the efficiency and safety of water chestnut peeling operations. It is especially suitable for batch peeling operations of water chestnuts. Attached Figure Description

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0043] like Figure 1 , Figure 2 , Figure 3, Figure 4 The automatic water chestnut peeling device shown includes a lifting conveyor belt 1, a posture-aligning conveyor belt 2, a sprocket conveyor mechanism 5, a water chestnut pressing mold mechanism 6, a water chestnut ring-cutting mechanism 7, and a shell-meat separation mechanism 8. A water chestnut posture-aligning mechanism 3 is installed above the posture-aligning conveyor belt 2. A differential speed conveyor belt 4 is installed at the output end of the posture-aligning mechanism 3, and the sprocket conveyor mechanism 5 is installed at the output end of the differential speed conveyor belt 4. Several water chestnut positioning molds 10 are installed on the sprocket conveyor mechanism 5, and a discharge chute 9 is provided at the output end of the sprocket conveyor mechanism 5. The specific structure of the water chestnut posture-aligning mechanism 3 is as follows: Figure 5 , Figure 6 As shown, the device includes a posture-correcting plate 307, a flow-limiting plate 308, a posture-correcting cam 303, and a driving mechanism thereof. The driving mechanism of the posture-correcting cam 303 is a posture-correcting motor 309. The posture-correcting cam 303 forms a relatively rotatable connection structure with one end of the posture-correcting connecting rod 304, and the other end of the posture-correcting connecting rod 304 forms a relatively rotatable connection structure with a first rocker arm 305. The posture-correcting plate 307 forms a relatively rotatable connection structure with one end of the first rocker arm 305 and one end of the second rocker arm 306, respectively. The other ends of the first rocker arm 305 and the second rocker arm 306 form relatively rotatable connection structures with the posture-correcting mounting base 301, respectively. Preferably, a posture-correcting connecting rod 310 can also be provided between the first rocker arm 305 and the second rocker arm 306, and the posture-correcting connecting rod 310 forms a rotatable connection structure with the first rocker arm 305 and the second rocker arm 306, respectively. The flow limiting plate 308 is connected to the posture correction rod 302. The posture correction rod 302 is driven by the posture correction cam 303 to perform reciprocating linear motion relative to the posture correction mounting base 301, thereby enabling the flow limiting plate 308 to also perform reciprocating linear motion relative to the posture correction mounting base 301.

[0044] The specific structure of the diamond-shaped molding mechanism 6 is as follows: Figure 7 , Figure 8 , Figure 9As shown, the device includes a flexible wheel 601 and its lifting and telescopic driving mechanisms. The flexible wheel 601 is mounted on a flexible wheel bracket 621 and rotates relative to the flexible wheel bracket 621. The flexible wheel bracket 621 is connected to the molding guide rail 603 via a molding connecting rod 612. The lifting driving mechanism of the flexible wheel 601 includes a first cantilever 609, a first molding cam 608, and a molding driving mechanism. The first cantilever 609 is movably connected to the molding mounting base 604 via a first connecting shaft 606, and the first cantilever 609 is connected to a first roller 602 and a second roller 605 respectively. The first roller 602 and the molding guide rail 603 form a relatively linear sliding fit structure. The molding drive mechanism includes a first pulley 607 and a second pulley 620. A first molding cam 608 and a second molding cam 615 are connected by a camshaft 619, which is fixedly connected to the second pulley 620. A belt drive structure is formed between the second pulley 620 and the first pulley 607 via a synchronous belt 611. The first pulley 607 is driven by a molding motor 616. Under the action of the molding drive mechanism, the first molding cam 608 rotates relative to the molding mounting base 604 and drives a first cantilever 609 via a second roller 605. The first cantilever 609 drives a flexible wheel 601 to move up and down within a certain range relative to the molding mounting base 604. Under the action of the molding drive mechanism, the second molding cam 615 rotates relative to the molding mounting base 604 and drives a second cantilever 617 via a third roller 614. The second cantilever 617 drives the flexible wheel 601 to move telescopically within a certain range relative to the molding mounting base 604. The telescopic drive mechanism of the flexible wheel 601 includes a second cantilever 617, a molding slider 610, and a second molding cam 615. The second cantilever 617 is movably connected to the molding mounting base 604 via a second connecting shaft 613, and the second cantilever 617 is connected to a third roller 614 and a fourth roller 618 respectively. The fourth roller 618 and the molding slider 610 form a movable connection structure.

[0045] like Figure 16 , Figure 17 , Figure 18As shown, the diamond-cutting mechanism 7 includes a first cutter 707 and a second cutter 708. The first cutter 707 is mounted on a first ring-cutting blade holder 706, and the second cutter 708 is mounted on a second ring-cutting blade holder 709. The blade openings of both the first cutter 707 and the second cutter 708 are arc-shaped, and the blade openings of the first cutter 707 and the second cutter 708 are positioned opposite each other. The first cutter 707 and the second cutter 708 move relative to each other through a blade holder drive mechanism, and the first cutter 707 and the second cutter 708 perform a ring-cutting action on the diamond during their relative closing motion. The tool holder drive mechanism includes a main push rod 702 and its drive mechanism. The main push rod 702 forms a sliding fit structure with the first slider 703 and the second slider 712. The first slider 703 forms a relatively rotatable connection structure with one end of the first circumferential cutting link 704 and one end of the second circumferential cutting link 710. The other end of the first circumferential cutting link 704 forms a movable connection structure with the circumferential cutting support 705. The other end of the second circumferential cutting link 710 forms a movable connection structure with the first circumferential cutting tool holder 706. The second slider 712 forms a relatively rotatable connection structure with one end of the third circumferential cutting link 711 and one end of the fourth circumferential cutting link 713. The other end of the third circumferential cutting link 711 forms a movable connection structure with the circumferential cutting support 705. The other end of the fourth circumferential cutting link 713 forms a movable connection structure with the second circumferential cutting tool holder 709. The driving mechanism of the main push rod 702 adopts the first electric push rod 701, and the main push rod 702 moves horizontally and linearly relative to the circumferential cutting support 705 under the action of its driving mechanism. It drives the first circumferential cutting blade holder 706 through the first slider 703 and the second circumferential cutting blade holder 709 through the second slider 712. The first circumferential cutting blade holder 706 drives the first cutter 707 and the second circumferential cutting blade holder 709 drives the second cutter 708, so that the first cutter 707 and the second cutter 708 form a circumferential cutting action during the relative closing movement.

[0046] After being ring-cut by the water chestnut ring-cutting mechanism 7, the water chestnuts are then peeled by the shell-meat separation mechanism 8. Figure 19 , Figure 20 , Figure 23 , Figure 24As shown, the shell and flesh separation mechanism 8 includes a first separation die 806, a second separation die 809, a die separation drive mechanism, a first jaw 808 and its drive mechanism, and a second jaw 810 and its drive mechanism. A diamond-shaped profile groove 817 is formed jointly on the first separation die 806 and the second separation die 809. The die separation drive mechanism includes a separation push plate 811 and its drive mechanism. A relatively rotatable movable connection structure is formed between the separation push plate 811 and the mounting plate 803. Opposite ends of the separation push plate 811 are respectively provided with relatively rotatable movable connection structures with one end of a first push rod 813 and one end of a second push rod 812. The other end of the first push rod 813 is connected to the first separation die 806. Preferably, the other end of the first push rod 813 can be connected to the first separation die 806 through a first slide plate 804. The other end of the second push rod 812 is connected to the second separation die 809. Preferably, the other end of the second push rod 812 can be connected to the second separation die 809 through a second slide plate 802. The first slide plate 804 and the second slide plate 802 are respectively in sliding fit with a guide slide rod 814. The drive mechanism of the separation push plate 811 uses a separation motor 805. The separation push plate 811 rotates under the action of its drive mechanism, and drives the first separation die 806 through the first push rod 813 and the second separation die 809 through the second push rod 812 until the first separation die 806 and the second separation die 809 are separated from each other in place.

[0047] The drive mechanism of the first jaw 808 includes a third electric push rod 807. One end of the first separation die 806 is fixedly connected to one end of a first cantilever rod 815. A movable connection structure is formed between the other end of the first cantilever rod 815 and the first jaw 808. The action output end of the third electric push rod 807 is provided with a movable connection structure with one end of the first jaw 808. The other end of the first jaw 808 forms a clamping end. The drive mechanism of the second jaw 810 includes a second electric push rod 801. One end of the second separation die 809 is fixedly connected to one end of a second cantilever rod 816. A movable connection structure is formed between the other end of the second cantilever rod 816 and the second jaw 810. The action output end of the second electric push rod 801 is provided with a movable connection structure with one end of the second jaw 810. The other end of the second jaw 810 forms a clamping end. The first jaw 808 and the second jaw 810 both perform clamping actions synchronously relative to the diamond-shaped profile groove 817 under the action of their respective drive mechanisms.

[0048] As Figure 1 shown, the main body of the present invention is arranged in a rectangular shape with a hole in the middle. The lifting conveyor belt 1 on the left can perform preliminary partial separation on the water chestnuts and make them enter the posture-correcting conveyor belt 2, and the water chestnut posture-correcting mechanism 3 corrects the postures of the water chestnuts. Specifically, as Figure 5 、 Figure 6 As shown, the posture-correcting motor 309 provides rotational power to the posture-correcting cam 303. The posture-correcting cam 303 makes point contact with the posture-correcting push rod 302, causing the posture-correcting push rod 302 to drive the flow-limiting plate 308 to reciprocate up and down to limit the flow at the corners. Simultaneously, since the posture-correcting cam 303 is connected to the posture-correcting connecting rod 304, the first rocker arm 305 and the second rocker arm 306 reciprocate, correcting the corners through the posture-correcting plate 307. When the tip of the posture-correcting cam 303 rotates to its lowest point, the posture-correcting push rod 302 is at its lowest point, and the flow-limiting plate 308 is retracted into the device. When the posture-correcting cam 303 starts to rotate, it lifts the posture-correcting push rod 302, which directly contacts the flow-limiting plate 308, thereby directly driving the flow-limiting plate 308 to move outward. Because the rhombus-shaped posture correction mechanism 3 is symmetrically arranged, the flow-limiting plates 308 on opposite sides move simultaneously to form a squeezing action, thereby achieving the function of separating a certain number of rhombuses. When the posture correction cam 303 is regarded as a crank and its tip is in the same straight line as the posture correction connecting rod 304, the first rocker arm 305 and the second rocker arm 306 are at the leftmost end; when the posture correction cam 303 starts to rotate, it drives the posture correction connecting rod 304 to move synchronously, thereby driving the first rocker arm 305 and the second rocker arm 306 to rotate to the right. At this time, the posture correction plate 307 slides to the right and moves upward at the same time. Because it is symmetrically arranged, in this movement, the oppositely arranged posture correction plates 307 can achieve a similar twisting motion, thereby achieving the purpose of rhombus-shaped posture correction.

[0049] After being corrected by the rhombus orientation mechanism 3, the rhombuses are then fed one by one onto the faster differential conveyor belt 4 for further separation. The rhombuses output from the differential conveyor belt 4 enter the rhombus positioning mold 10 on the sprocket conveyor mechanism 5 and move together with it. Since the rhombuses' posture may be disturbed during their entry into the positioning mold 10, the rhombus pressing mechanism 6 squeezes the rhombuses onto the positioning mold 10, ensuring a tighter fit between the rhombuses and the mold. The working process of the rhombus pressing mechanism 6 includes three pressing processes, specifically:

[0050] Molding process 1, such as Figure 10 , Figure 11 As shown, the molding motor 616 starts, driving the first pulley 607 to rotate, which in turn drives the second pulley 620 to rotate via the synchronous belt 611. Since the second pulley 620, the first molding cam 608, and the second molding cam 615 are mounted on the same camshaft 619, during rotation, the second pulley 620 drives the first molding cam 608 and the second molding cam 615 to rotate via the camshaft 619. The first molding cam 608 rotates counterclockwise under the action of the camshaft 619, and the second molding cam 615 rotates clockwise under the action of the camshaft 619, while the two remain relatively stationary.

[0051] Molding process 2, such as Figure 12 , Figure 13 As shown, the second pressing cam 615 rotates clockwise, pushing the second cantilever 617 through the third roller 614 in point contact with the second pressing cam 615, causing the second cantilever 617 to rotate clockwise around the second connecting shaft 613. During this process, the second pressing cam 615 is in the pushing state, while the first pressing cam 608 is in the resting state. While the second cantilever 617 rotates clockwise under the pushing force of the second pressing cam 615, it pushes the pressing slider 610 out through the fourth roller 618 in point contact with the pressing slider 610. When the pressing slider 610 is pushed out, it can simultaneously push out the pressing guide rail 603 and the flexible wheel bracket 621 connected to the pressing guide rail 603.

[0052] Molding process 3, such as Figure 14 , Figure 15 As shown, the first pressing cam 608 enters the return state, the first cantilever 609 makes point contact with the second roller 605, and the first cantilever 609 falls clockwise around the first connecting shaft 606 under its own gravity. Since the first roller 602 forms point contact with the groove on the pressing guide rail 603, the first roller 602 drives the flexible wheel bracket 621 and the flexible wheel 601 to fall as a whole under the guidance of the groove on the pressing guide rail 603. During this process, the second pressing cam 615 is in a resting state, so the pressing action of the diamond can be completed by using the flexible wheel 601.

[0053] Once the water chestnut in the water chestnut positioning mold 10 is fitted and firmly fixed by the water chestnut pressing mechanism 6, the water chestnut can be ring-cut by the water chestnut ring-cutting mechanism 7 for subsequent shell-meat separation. Specifically, as... Figure 16-18As shown, the first electric push rod 701 is activated, driving the main push rod 702 to move horizontally. The first slider 703 slides along the main push rod 702 and relative to it. Since the first slider 703 is connected to the first circumferential cutting link 704 and the second circumferential cutting link 710 respectively, forming a triangular structure between them, and the first circumferential cutting link 704 is connected between the circumferential cutting support 705 and the first slider 703, and the second circumferential cutting link 710 is connected between the first circumferential cutting blade holder 706 and the first slider 703, when the main push rod 702 advances, the first slider 703 is squeezed and slides towards the far end of the main push rod 702. This increases the angle between the first circumferential cutting link 704 and the second circumferential cutting link 710, thereby driving the first circumferential cutting blade holder 706 to slide relative to the circumferential cutting support 705 and move closer to the main push rod 702. Similarly, when the first electric push rod 701 is activated, it drives the main push rod 702 to move horizontally, causing the second slider 712 to slide along the main push rod 702 and relative to it. Since the second slider 712 is connected to the third circumferential cutting link 711 and the fourth circumferential cutting link 713 respectively, forming a triangular structure between the third circumferential cutting link 711 and the fourth circumferential cutting link 713, and the third circumferential cutting link 711 is connected between the circumferential cutting support 705 and the second slider 712, and the fourth circumferential cutting link 713 is connected between the second circumferential cutting tool holder 709 and the second slider 712, when the main push rod 702 is advanced, the second slider 712 is squeezed and slides towards the far end of the main push rod 702, thereby increasing the included angle between the third circumferential cutting link 711 and the fourth circumferential cutting link 713, which in turn drives the second circumferential cutting tool holder 709 to slide relative to the circumferential cutting support 705 and moves the second circumferential cutting tool holder 709 closer to the main push rod 702. As the first ring cutter holder 706 and the second ring cutter holder 709 move toward the main push rod 702 in sync, the first cutter 707 and the second cutter 708 can move toward each other, thus achieving the ring cutting action on the diamond.

[0054] After the ring-cutting process, the water chestnuts undergo shell-meat separation by the shell-meat separation mechanism 8. Specifically, as follows... Figure 19 , Figure 22As shown, since the first separating mold 806 and the second separating mold 809 together form a rhombus-shaped groove 817, the rhombus can fit better into the rhombus-shaped groove 817 on the mold. The second electric push rod 801 drives the second gripper 810, and the third electric push rod 807 drives the first gripper 808 to simultaneously form a clamping action relative to the rhombus-shaped groove 817. By using the cooperation between the first gripper 808 and the second gripper 810, the two ends of the rhombus shell can be clamped respectively. Simultaneously, the separation motor 805 drives the separation push plate 811 to rotate, which in turn drives the first push rod 813 and the second push rod 812 to move synchronously. The first push rod 813 drives the first sliding plate 804, and the second push rod 812 drives the second sliding plate 802. Since the first sliding plate 804 is connected to the first separation mold 806, and the second sliding plate 802 is connected to the second separation mold 809, the synchronous movement of the first push rod 813 and the second push rod 812 causes the first separation mold 806 and the second separation mold 809 to separate. This causes the already opened water chestnut in the water chestnut contour groove 817 to be separated into two parts along with the separation of the first separation mold 806 and the second separation mold 809, while the water chestnut meat is not clamped. Figure 23 , Figure 24 , Figure 25 As shown. Since the water chestnut meat is unrestrained, it can be poured into the discharge trough 9, as... Figure 1 , Figure 3 As shown. The water chestnut shell is clamped onto the first separating mold 806 and the second separating mold 809 by the first gripper 808 and the second gripper 810, respectively, as shown. Figure 23 As shown. After the first separating mold 806 and the second separating mold 809 leave the discharge trough 9, the third electric push rod 807 drives the first gripper 808 and the second electric push rod 801 to drive the second gripper 810 in the opposite direction, so that both ends of the water chestnut shell can be released. At this time, the water chestnut shell falls into the collection basket due to its own gravity, thus realizing the separation of the water chestnut shell and meat.
