Description

Technical Field

[0001] The invention relates to the technical field of kitchen utensils, in particular to a semi-automatic broad bean pod sheller. Background Art

[0002] Broad beans are a popular agricultural and sideline product with high edible value, delicious taste and rich in vitamins. People need to peel the pods before eating. There are only a handful of broad bean peeling machines on the market, and they are all medium-sized or large machines with complex working principles and high production costs. For individual farmers who grow broad beans or families who like to eat broad beans, using broad bean peeling machines to peel the beans is a bit of a waste of resources. Usually, they are peeled manually, which is not only inefficient, but also takes a lot of time and is most harmful to nails and fingers. Summary of the invention

[0003] The technical problem to be solved by the invention is: in order to overcome the problems that peeling broad bean pods by hand is not only inefficient, but also takes a lot of time and hurts nails and fingers, a semi-automatic broad bean pod sheller is provided.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a semi-automatic broad bean pod sheller, comprising:

[0005] Fixed seat: The fixed seat is provided with a through hole for the broad bean fruit to pass through;

[0006] Limiting cylinder: the lower end of the limiting cylinder is detachably mounted on the fixing seat, the limiting cylinder is connected to the through hole, and a limiting plate for limiting the broad bean pod shell from moving out of the limiting cylinder is fixedly mounted on the bottom end of the inner wall of the limiting cylinder;

[0007] Guide cylinder: The guide cylinder is coaxially fixedly mounted on the upper end of the limiting cylinder, and the inner cavity of the guide cylinder is a guide hole, which limits the broad bean to move along it in a vertical state;

[0008] The tool comprises a knife tip, a spreading guide portion and a spreading portion which are arranged in sequence. The knife tip is in a triangular pyramid shape and is fixedly mounted on the inner wall of the guide hole, and is used to cut open one of the broad bean tendons connecting the two broad bean pod shells. The spreading guide portion is narrow at the top and wide at the bottom, and is fixed on the inner wall of the limiting cylinder to gradually spread open the two broad bean pod shells. The spreading portion is fixedly mounted on the inner wall of the limiting cylinder and is arranged opposite to the limiting plate, and is used to spread open the two broad bean pod shells. The spreading guide portion and the spreading portion are both arranged along the axial direction of the guide cylinder.

[0009] Push rod: The push rod is inserted into the guide hole and is used to push the broad bean fruit out of the limiting cylinder. The insertion end of the push rod is fixedly installed with an upwardly bent hook.

[0010] The semi-automatic broad bean pod sheller of the present invention can be used to place a fixed seat on a container, and broad beans can be vertically placed in the guide hole. The guide hole restricts the broad beans from moving along the guide hole in a vertical state. When the broad beans come into contact with the knife tip in the guide hole, the knife tip pushes the broad beans to press against the inner wall of the guide hole opposite to the knife tip because the knife tip is in a triangular pyramid shape. The broad beans are manually pushed downward, and the knife tip comes into contact with the broad bean tendons to split the broad bean tendons. The two broad bean pod shells of the broad beans are supported by the knife. The guide part is narrow at the top and wide at the bottom, and the two broad bean pod shells are gradually stretched open. If the broad beans are completely in the guide hole at this time, a push rod can be used to make one end with a hook contact with the broad bean fruit. The push rod pushes the broad bean fruit to move downward, and the broad bean fruit drives the broad bean pod shell to move downward together. The two broad bean pod shells move from the stretching guide part to the stretching part, and the stretching part stretches the two broad bean pod shells open. The broad bean pod shell continues to move downward along the stretching part. Since the stretching part is fixedly installed in the limit cylinder, The broad bean pod shell is necessarily in contact with the limiting plate during the downward movement. After the broad bean pod shell contacts the limiting plate at the lower end of the limiting cylinder, the limiting plate limits the broad bean pod shell from continuing to move downward. The push rod pushes the broad bean fruit to continue to move downward. The broad bean fruit is separated from the broad bean pod shell under the push of the push rod and then peeled off from the broad bean pod shell. The peeled broad bean fruit enters the container from the through hole, and then the push rod is pulled out of the guide hole. When the push rod is pulled out, the lower end of the push rod needs to be The push rod is tilted and pulled out toward the broad bean pod shell. After the lower end of the push rod is tilted toward the broad bean pod shell, the curved hook on the push rod can hook the broad bean pod shell out of the limiting cylinder, and the broad bean peeling is completed. The invention has a simple structure, is easy to operate, and has a high shelling efficiency. The broad bean fruit can be peeled out of the broad bean pod shell without using fingernails, which protects fingernails and fingers and is convenient for individual farmers who grow broad beans and families who like to eat broad beans. The limiting cylinder is detachably connected to the fixing seat, which is convenient for the disassembly of the invention and makes the invention easy to store and store.

[0011] Since the two ends of the broad bean are relatively thin, after the broad bean enters the guide hole, in order to make the tip of the knife able to cut open the broad bean tendons at the ends of the broad bean, the length of the tip of the knife protruding from the inner wall of the guide hole needs to be made longer. A longer tip of the knife is likely to scratch the broad bean fruit in the broad bean pod shell, so the tip of the knife needs to be made shorter. After the tip of the knife is shortened, the tip of the knife will not be able to reach the broad bean tendons at the thinner ends, and the broad bean tendons cannot be completely cut open. In order to solve the above problem, the present invention also includes a corner cutting knife, and there are two corner cutting knives, both of which are fixedly mounted on a fixed seat, and the two corner cutting knives are parallel and spaced apart. The corner cutting knife can cut off the two ends of the broad bean, and there are no fruits at the two ends of the broad bean. After the ends without fruits are cut off, the thickness of the remaining broad beans is relatively uniform, and the tip of the knife can completely cut open the broad bean tendons.

[0012] In order to protect the corner cutting knives and prevent the user from being injured by the corner cutting knives, tool protection covers for protecting the corner cutting knives are provided outside the two corner cutting knives.

[0013] In order to facilitate the collection of peeled broad bean fruits, the present invention also includes a broad bean fruit storage box, the lower surface of the fixed seat is fixedly installed with an annular limiting protrusion, the through hole is located in the annular limiting protrusion, the annular limiting protrusion is inserted in the broad bean fruit storage box, and the fixed seat is supported on the broad bean fruit storage box. The broad bean fruits can pass through the through hole from the limiting cylinder and finally fall into the broad bean fruit storage box.

[0014] In order to prevent the broad bean fruit from being damaged by the opening guide part and the opening part of the cutter, the opening guide part and the opening part of the cutter are both provided with fruit guide openings, and the fruit guide openings are arranged along the axial direction of the limiting cylinder.

[0015] Preferably, the cross-sectional shape of the guide hole is elliptical, the knife tip has a blade, the blade is arranged along the long axis of the ellipse, the cross-sectional shape of the broad bean is close to an ellipse, and the cross-sectional shape of the guide hole is designed to be elliptical, which can better restrict the broad bean from moving in a vertical state along the guide hole.

[0016] The push rod is inserted into the guide hole, so the radius of the push rod must be smaller than the short axis of the guide hole. In order to prevent the push rod from being completely inserted into the guide hole and being inconvenient to remove, a holding ball for easy holding is fixedly installed on the end of the push rod away from the hook. The radius of the holding ball is larger than the short axis length of the guide hole. The holding ball can limit the push rod from being completely inserted into the guide hole.

[0017] In order to realize the detachable installation of the limiting cylinder on the fixing seat, a mounting ring is fixedly installed on the fixing seat, the mounting ring is coaxially arranged with the through hole, the inner radius of the mounting ring is larger than the radius of the through hole, the limiting cylinder is inserted in the mounting ring, and the outer circumferential surface of the limiting cylinder is in contact with the inner circumferential surface of the mounting ring.

[0018] In order to facilitate taking out the broad bean pod shell in the limiting cylinder, the inner wall of the guide hole and the inner wall of the limiting cylinder are smoothly transitionally connected.

[0019] The beneficial effects of the present invention are as follows: when the semi-automatic broad bean pod sheller of the present invention is used, the fixing seat can be placed on the container, and the broad beans can be vertically placed in the guide hole. The guide hole restricts the broad beans from moving along the guide hole in a vertical state. When the broad beans come into contact with the knife tip in the guide hole, the knife tip pushes the broad beans to press against the inner wall of the guide hole opposite to the knife tip because the knife tip is in a triangular pyramid shape. The broad beans are manually pushed downward, and the knife tip comes into contact with the broad bean tendons to split the broad bean tendons, so that the two silkworm lobes of the broad bean can be peeled off. The bean pod shell contacts the opening guide part of the cutter, which is narrow at the top and wide at the bottom, and gradually opens the two halves of the broad bean pod shell. If the broad beans are completely in the guide hole at this time, a push rod can be used to contact one end with a hook with the broad bean fruit. The push rod pushes the broad bean fruit to move downward, and the broad bean fruit drives the broad bean pod shell to move downward together. The two halves of the broad bean pod shell move from the opening guide part to the opening part, and the opening part opens the two halves of the broad bean pod shell. The broad bean pod shell continues to move downward along the opening part. Since the opening part is fixedly installed The broad bean pod shell is arranged on the inner wall of the limiting cylinder and is opposite to the limiting plate. The broad bean pod shell must contact the limiting plate during the downward movement. After the broad bean pod shell contacts the limiting plate located at the lower end of the limiting cylinder, the limiting plate restricts the broad bean pod shell from continuing to move downward. The push rod pushes the broad bean fruit to continue to move downward. The broad bean fruit is separated from the broad bean pod shell under the push of the push rod, and then peeled off from the broad bean pod shell. The peeled broad bean fruit enters the container from the through hole, and then the push rod is pulled out of the guide hole. When the push rod is pulled out, the push rod needs to be The lower end of the push rod is tilted toward the broad bean pod shell and pulled out. After the lower end of the push rod is tilted toward the broad bean pod shell, the curved hook on the push rod can hook the broad bean pod shell out of the limiting cylinder, and the broad bean peeling is completed. The invention has a simple structure, is easy to operate, and has a high shelling efficiency. The broad bean fruit can be peeled out of the broad bean pod shell without using fingernails, which protects fingernails and fingers and is convenient for individual farmers who grow broad beans and families who like to eat broad beans. The limiting cylinder is detachably connected to the fixing seat, which is convenient for the disassembly of the invention and makes the invention easy to store and store.

The guide cylinder 4 is coaxially fixedly installed at the upper end of the limiting cylinder 2, and the inner cavity of the guide cylinder 4 is a guide hole 4-1, and the inner wall of the guide hole 4-1 is smoothly connected to the inner wall of the limiting cylinder 2. The cross-sectional shape of the guide hole 4-1 is an ellipse, as shown in FIG. Figure 6As shown, the cross section of the broad bean is close to an ellipse. Designing the cross section of the guide hole 4-1 to be an ellipse can better restrict the broad bean from moving along the guide hole 4-1 in a vertical state.

[0033] The tool 5 comprises a tool tip 5-1, a support guide portion 5-2 and a support portion 5-3 arranged in sequence. The tool tip 5-1 is in a triangular pyramid shape and is fixedly mounted on the inner wall of the guide hole 4-1. Figure 2 As shown, it is used to cut open one of the broad bean tendons 13 connecting two halves of broad bean pod shell 12, the knife tip 5-1 has a blade 5-1-1, and the blade 5-1-1 is arranged along the major axis of the ellipse, the opening guide portion 5-2 is narrow at the top and wide at the bottom, fixed on the inner wall of the limiting tube 2 for gradually opening the two halves of the broad bean pod shell 12, the opening portion 5-3 is fixedly mounted on the inner wall of the limiting tube 2 and arranged opposite to the limiting plate 3, and is used to open the two halves of the broad bean pod shell 12, the opening guide portion 5-2 and the opening portion 5-3 are both arranged along the axial direction of the guide tube 4; in order to prevent the broad bean fruit from being damaged by the opening guide portion 5-2 and the opening portion 5-3 of the tool 5, the opening guide portion 5-2 and the opening portion 5-3 of the tool 5 are both provided with a fruit guiding opening 5-4, as shown Figure 7 As shown, the fruit guide opening 5-4 is arranged along the axial direction of the limiting tube 2; the cross-sectional shapes of the expansion guide part 5-2 and the expansion part 5-3 of the tool 5 are both fan-shaped, and the arc surfaces of the fan-shaped expansion guide part 5-2 and the expansion part 5-3 are fitted with the inner circumferential surface of the limiting tube 2, and the fruit guide opening 5-4 is opened with the vertex of the fan as the center of the circle, thereby reducing the height of the expansion guide part 5-2 and the expansion part 5-3 protruding from the inner wall of the limiting tube 2, which can avoid damage to the broad bean fruit; the tip 5-1, the expansion guide part 5-2 and the expansion part 5-3 of the tool 5 are an integrated manufacturing structure, the inner wall of the guide hole 4-1 and the inner wall of the limiting tube 2 are smoothly transitioned, and an installation opening that fits the arc transition section is opened at the connection between the tip 5-1 and the expansion guide part 5-2.

[0034] The push rod 6 is inserted into the guide hole 4-1 and is used to push the broad bean fruit out of the limiting cylinder 2. The insertion end of the push rod 6 is fixedly mounted with a hook 7 bent upward. Figure 8 As shown; a holding ball 11 for easy holding is fixedly installed on the end of the push rod 6 away from the hook 7. The radius of the holding ball 11 is larger than the short axis length of the guide hole 4-1. The holding ball 11 can limit the push rod 6 to be fully inserted into the guide hole 4-1. The length of the push rod 6 is preferably larger than the sum of the height of the limit cylinder 2 and the height of the guide cylinder 4.

[0035] Since the ends of broad beans are thinner, Fig. 9As shown, after the broad beans enter the guide hole 4-1, if the knife tip 5-1 is to be able to cut the broad bean ribs 13 at the end of the broad beans, the length of the knife tip 5-1, that is, the length of the knife tip 5-1 protruding from the inner wall of the guide hole 4-1, needs to be made longer. The longer knife tip 5-1 is easy to scratch the broad bean fruit in the broad bean pod shell 12, so the knife tip 5-1 needs to be made shorter. After the knife tip 5-1 is shortened, the knife tip 5-1 will not be able to reach the broad bean ribs 13 at the thinner end, and the broad bean ribs 13 cannot be completely cut. In order to solve the above problem, the present invention also includes a corner cutting knife 8, the There are two corner cutting knives 8 5 , both of which are fixedly mounted on the fixed seat 1 , and the two corner cutting knives 8 are parallel and spaced apart, both of which are quarter-circular, and the blade 5-1-1 is arc-shaped, and the blades 5-1-1 of the two corner cutting knives 8 face the same direction, and the distance between the two corner cutting knives 8 is less than the average length of the broad beans, and the corner cutting knives 8 can cut off both ends of the broad beans, and there are no fruits at both ends of the broad beans, and after the ends without fruits are cut off, the thickness of the remaining broad beans is relatively uniform, and the knife tip 5-1 can completely split the broad bean tendons 13. In order to protect the corner cutting knives 8 and prevent the user from being injured by the corner cutting knives 8 , the two corner cutting knives 8 are both covered with a tool protection cover 9 for protecting the corner cutting knives 8 .

[0036] In order to facilitate the collection of peeled broad bean fruits, the present invention also includes a broad bean fruit storage box 10, which is used in conjunction with the present invention. A ring-shaped limiting protrusion 1-2 is fixedly installed on the lower surface of the fixed seat 1, and the through hole 1-1 is located in the ring-shaped limiting protrusion 1-2. The ring-shaped limiting protrusion 1-2 is inserted in the broad bean fruit storage box 10. The fixed seat 1 is supported on the broad bean fruit storage box 10, and the broad bean fruits can pass through the through hole 1-1 from the limiting cylinder 2 and finally fall into the broad bean fruit storage box 10.

[0037] The semi-automatic broad bean pod shell peeling tool of the present invention can be used to insert the annular limiting protrusion 1-2 on the fixing seat 1 into the broad bean fruit storage box 10, and the broad beans to be peeled are held horizontally by hand, and the two ends of the broad beans are respectively aligned with the two corner cutting knives 8, and the broad beans are pushed toward the corner cutting knives 8. The corner cutting knives 8 cut off the two ends of the broad beans, and the broad beans with the two ends cut off are vertically placed in the guide holes 4-1. The guide holes 4-1 limit the broad beans to move along them in a vertical state. There are no fruits at the two ends of the broad beans, and after the ends without fruits are cut off, the thickness of the remaining broad beans is relatively uniform. When the broad beans come into contact with the knife tip 5-1 in the guide hole 4-1, since the knife tip 5-1 is in the shape of a triangular pyramid, The broad bean is pushed downward manually, and the broad bean is cut open after the blade tip 5-1 contacts the broad bean tendon 13 of the broad bean. The two broad bean pod shells 12 of the broad bean contact the opening guide part 5-2 of the cutter 5, and the opening guide part 5-2 is narrow at the top and wide at the bottom, and the two broad bean pod shells 12 are gradually opened. If the broad bean completely enters the guide hole 4-1 at this time, the push rod 6 can be used to contact one end with the hook 7 with the broad bean fruit, and the push rod 6 pushes the broad bean fruit to move downward, and the broad bean fruit drives the broad bean pod shell 12 to move downward together, and the two broad bean pod shells 12 are moved out of the opening guide part 5- 2 moves toward the opening part 5-3, the opening part 5-3 opens the two-petal broad bean pod shell 12, and the broad bean pod shell 12 continues to move downward along the opening part 5-3. Since the opening part 5-3 is fixedly installed on the inner wall of the limiting cylinder 2 and is arranged opposite to the limiting plate 3, the broad bean pod shell 12 must contact the limiting plate 3 during the downward movement. After the broad bean pod shell 12 contacts the limiting plate 3 located at the lower end of the limiting cylinder 2, the limiting plate 3 restricts the broad bean pod shell 12 from continuing to move downward, and the push rod 6 pushes the broad bean fruit to continue to move downward along the fruit guide opening 5-4. The broad bean fruit is separated from the broad bean pod shell 12 under the push of the push rod 6, and then peeled off from the broad bean pod shell 12. The fruit enters the container from the through hole 1-1, and then the push rod 6 is pulled out of the guide hole 4-1. When pulling out the push rod 6, the lower end of the push rod 6 needs to be tilted toward the broad bean pod shell 12 for pulling out. After the lower end of the push rod 6 is tilted toward the broad bean pod shell 12, the curved hook 7 on the push rod 6 can hook the broad bean pod shell 12 out of the limiting tube 2, and the broad bean peeling is completed. The present invention has a simple structure, is easy to operate, and has a high peeling efficiency. The broad bean fruit can be peeled out of the broad bean pod shell 12 without using fingernails, which protects fingernails and fingers and is convenient for individual farmers who grow broad beans and families who like to eat broad beans. The limiting tube 2 is detachably connected to the fixing seat 1, which is convenient for the disassembly of the present invention and makes the present invention easy to receive and store.
