Description

Technical Field

[0001] The invention relates to the technical field of crop harvesting, and in particular to a garlic root removal device. Background Art

[0002] Crops such as garlic, onion, wild garlic, and shallot have similar shapes. Taking garlic as an example, domestic garlic harvesting is mainly done manually. Garlic farmers use digging shovels to dig out garlic from the garlic field one by one, and then use scissors to cut the stems and roots one by one. The entire garlic harvesting process is extremely inefficient, resulting in very expensive manual garlic harvesting costs.

[0003] Garlic root cutting and straw removal devices on the market, such as Figure 1 As shown, the garlic stalk is clamped to pull the garlic head to a support surface above the garlic head, and a group of root cutting knives are arranged below the garlic head to cut the roots; after the root cutting is completed, the garlic stalk is continued to be clamped and moved forward to enter the stalk cutting knife arranged above the garlic head to cut the stalk. The root cutting method of the above scheme is based on the top of the garlic head for positioning, but for garlic heads of different sizes, the cutting position of the root cutting knife is inconsistent. In order not to damage the garlic, the position of the root cutting knife can only be arranged according to the size of the largest garlic head. Obviously, when the smaller garlic heads pass by, the roots will inevitably not be cut cleanly. In addition, since the feeding posture of garlic cannot be controlled during harvesting, garlic fed at an angle is very susceptible to damage.

[0004] Therefore, it is necessary to provide a device that can completely remove the garlic roots and stalks of garlic of different sizes and different feeding postures without damaging the garlic body. Summary of the invention

[0005] The purpose of the present invention is to provide a garlic root cutting device, which utilizes a certain angle between a positioning support frame and a transmission direction of a root clamping transmission guide rail to correct the position of garlic when it is cut during the transmission process, thereby solving the problem of incomplete root cutting or damaged cutting.

[0051] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0052] Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0053] In the description of the present invention, it should be noted that the terms “first”, “second” and “third” are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0054] The present invention provides a garlic root removal device, comprising:

[0055] A frame that can be set on a support surface;

[0056] A positioning support frame 1, which is arranged on the frame and includes a support surface, and the support surface forms a support channel in the first transmission direction;

[0057] A root-clamping transmission guide rail 2, wherein a transmission channel capable of collecting and transmitting garlic roots is formed in the root-clamping transmission guide rail 2 along a second transmission direction;

[0058] The first transmission direction and the second transmission direction form a set angle, and the support channel intersects and communicates with the transmission channel;

[0059] The first cutting member 13 is arranged on the frame and includes a cutting surface capable of performing face cutting; the cutting surface is parallel to the supporting surface and is located between the root clamping transmission guide rail 2 and the positioning support frame 1 .

[0060] The positioning support frame and the root clamping transmission guide rail of the present invention have a certain angle in the transmission direction, which can realize the correction and fixation of the position of the crops on the positioning support frame during the transmission process, so that the first cutting member can cut the root system perpendicular to the center line of the crops, solving the problem of incomplete root cutting or damaged cutting.

[0061] The garlic root removal device of the present invention is described below by taking the processing method of garlic roots and garlic stalks as an example.

[0062] Embodiment 1:

[0063] Figure 2 The structure of the garlic root cutting device of the first embodiment of the present invention is shown, including: a frame (not shown in the figure), a positioning support frame 1, a root clamping transmission guide rail 2 and a first cutting member 13. The positioning support frame 1, the root clamping transmission guide rail 2 and the first cutting member 13 are all arranged on the frame accordingly. The frame is arranged on a supporting plane that can support its installation. The supporting plane can be a horizontal plane or an inclined plane according to the actual use environment. In this embodiment, installation on a horizontal plane is taken as an example.

[0064] Specifically, the root clamping transmission guide rail 2 includes two parallel and synchronously transmitted monorails, and the extension direction of the rails is the second transmission direction; there is a set spacing between the two monorails that can clamp the width of the garlic root system, and the spacing serves as a transmission channel for transmitting the garlic along the second transmission direction;

[0065] The positioning support frame 1 includes: a positioning surface 12, which is formed by two parallel stationary monorails, and the extension direction of the rails is the first transmission direction; the gap between the two monorails forms a support channel, and the spacing of the support channel is smaller than the diameter of the garlic, so that the garlic root passes through while the bottom of the garlic is fully in contact with the support frame 1 and moves along the first transmission direction.

[0066] The positioning support frame 1 and the root clamping transmission guide rail 2 are arranged on the frame along a direction perpendicular to the support plane, and the second transmission direction of the root clamping transmission guide rail 2 is parallel to the support plane; preferably, the positioning support frame 1 is located at one end of the root clamping transmission guide rail 2 facing the support plane; it can also be located at the end away from the support plane.

[0067] Specifically, the support channel intersects and communicates with the transmission channel, and the first transmission direction and the second transmission direction form a set angle, so that the garlic heads are transmitted along the support channel driven by the root-clamping transmission guide rail 2, and the garlic roots are transmitted along the horizontal second transmission direction to tighten the garlic roots;

[0068] Preferably, the positioning support frame 1 is provided with an introduction part 11 at the intersection of the support channel and the transmission channel, and the spacing of the introduction parts 11 is slightly larger than the width of the support channel, so as to facilitate the transmission of garlic from the second transmission direction to the first transmission direction.

[0069] After the garlic is transferred into the positioning support frame 1, the distance between the bottom of the garlic and the clamping position of the garlic root becomes farther and farther, so that the garlic root is tightened during the transmission in the second transmission direction. At this time, the garlic is only subjected to the pulling force of the garlic root and the reaction force of the supporting surface. Since there is no force above the garlic, the bottom of the garlic will be closely attached to the supporting surface of the positioning support frame 1 under the action of the pulling force of the garlic root, so that the center line of the garlic and the supporting surface tend to be vertical, completing the positioning and correction of the garlic before root cutting.

[0070] Optionally, the positioning support frame 1 is a flexible conveyor belt. In this case, after the garlic is corrected, it continues to be transported along the first conveying direction under the joint action of the root clamping conveying guide rail 2 and the flexible conveyor belt.

[0071] In the present embodiment, since the garlic root has a certain toughness, when the clamping force of the root clamping transmission guide rail is less than the tensile strength of the garlic root, the garlic root can slide relative to the root clamping transmission guide rail after being tightened to avoid the breakage of the garlic root; due to the set angle between the first transmission direction and the second transmission direction, the garlic head and the positioning surface slide relative to each other after the garlic root is fully tightened, so as to achieve the purpose of positioning and correction, and avoid the situation in which the garlic head is damaged due to the deviation of the cutting position caused by the feeding posture such as the garlic head turning forward or leaning back or the shape of the garlic itself in the subsequent root cutting operation.

[0072] Continue to see Figure 2, under the combined action of the clamping root transmission guide rail 2 and the positioning support frame 1, the corrected garlic bulbs will continue to be transmitted along the first transmission direction and reach the position of the first cutting member 13 for root cutting.

[0073] Specifically, as Figure 3 shown, the first cutting member 13 is parallel to the support surface and is arranged below the positioning surface 12, and is as close to the support surface as possible while not affecting the operation of the first cutting member 13. At the same time, the positioning surface 12 is as thin as possible so that the first cutting member 13 cuts as close to the garlic bottom plate as possible to cut the garlic roots cleanly;

[0074] Optionally, the position of the first cutting member 13 is controlled by means of a motor, hydraulic pressure or mechanical structure, etc. to achieve the best cutting effect.

[0075] In this embodiment, a pair of relatively thin disc knives that rotate relative to each other perform a reverse rotation movement or a blade staggered cutting method to complete the root cutting action. The distance between the cutting edge of the first cutting member 13 and the intersection of the first transmission direction and the second transmission direction should be appropriately adjusted according to the position of the clamped root and the angle between the positioning support frame and the clamping root transmission guide rail to ensure that the root cutting action is completed before the garlic bulb moves out of the clamping root device.

[0076] Optionally, a strip saw that can move parallel to the support surface and cover the support channel is arranged below the positioning surface 12.

[0077] After root cutting, the garlic bulbs leave the transmission device under the action of inertia or other auxiliary transmission devices and are collected uniformly.

[0078] In a preferred method, in order to guide the roots of the garlic into the clamping root transmission guide rail 2, a bracket 4 is arranged on the frame. The bracket 4 is located at one end of the clamping root transmission guide rail 2 and is arranged in sequence with the end of the clamping root transmission guide rail 2 in the direction perpendicular to the support plane;

[0079] The bracket 4 has a bracket extension direction and forms a first channel along this extension direction for the garlic roots to pass through; the bracket extension direction is the horizontal direction, so that the garlic is introduced from the bracket 4 into the clamping root transmission guide rail 2, and after being transmitted along the second transmission direction, it enters the positioning support frame 1 and continues to be transmitted along the first direction.

[0080] The bracket 4 and the clamping root transmission guide rail 2 have a set spacing, which is set according to the situation of the garlic roots to facilitate the clamping root transmission guide rail 2 to clamp the garlic roots; the bracket 4 can also be closely attached to the clamping root transmission guide rail 2.

[0081] In other embodiments, the clamping root transmission guide rail 2 includes: a lifting part 21 and a clamping part 22. The lifting part 21 and the clamping part 22 are of an integral structure, and the same transmission belt is used to guide the roots of the garlic into the clamping part 22, as Figure 4 shown, the spacing of the lifting part 21 is not less than the width of the transmission channel.

[0082] In other embodiments, the root clamping transmission guide rail 2 can also realize the transmission function through existing technologies such as transmission belts, chains, etc. in conjunction with tensioning mechanisms.

[0083] In other embodiments, the positioning support frame 1 can be a stationary track made of smooth metal, plastic, glass, etc. but not limited to the above materials and having a certain anti-deformation effect.

[0084] In other embodiments, the supporting portion 21 and the introduction portion 11 that first contact the garlic root are both in a trumpet shape to ensure that the garlic root is fully introduced and clamped and the garlic bulb is smoothly introduced.

[0085] In other embodiments, the positioning support frame 1 is rotatably connected to the frame via a rotating shaft, so that a plurality of set angles can be formed between the first transmission direction and the second transmission direction.

[0086] Embodiment 2:

[0087] Figure 5 The structure of the garlic root cutting device according to the second embodiment of the present invention is shown, which includes: a frame (not shown in the figure), a positioning support frame 1, a root clamping transmission guide rail 2 and a first cutting member 13. The positioning support frame 1, the root clamping transmission guide rail 2 and the first cutting member 13 are all arranged on the frame accordingly, and the frame is arranged on a supporting plane capable of supporting its installation.

[0088] Specifically, the root clamping transmission guide rail 2 includes two parallel and synchronously transmitted monorails, and the extension direction of the rails is the second transmission direction; there is a set spacing between the two monorails that can clamp the width of the garlic root system, and the spacing serves as a transmission channel for transmitting the garlic after the root system is folded along the second transmission direction;

[0089] The positioning support frame 1 includes: an introduction portion 11 and a positioning surface 12. In this embodiment, the positioning surface 12 is formed by two parallel and synchronously driven monorails, and the extension direction of the rails is the first transmission direction; the gap between the two monorails forms a support channel, and the spacing of the support channel is smaller than the diameter of the garlic, so that the garlic root passes through while the bottom of the garlic is fully in contact with the support frame 1 and moves along the first transmission direction;

[0090] The spacing of the introduction parts 11 may be slightly larger than the width of the support channel of the positioning surface 12 , so as to support the garlic heads and guide the garlic bodies into the positioning surface 12 .

[0091] The positioning support frame 1 and the root clamping transmission guide rail 2 are arranged on the frame along a direction perpendicular to the support plane, and the first transmission direction of the positioning support frame 1 is parallel to the support plane; preferably, the root clamping transmission guide rail 2 is located at the end of the positioning support frame 1 facing the support plane; it can also be located at the end away from the support plane.

[0092] Specifically, the support channel intersects and communicates with the transmission channel, and the first transmission direction and the second transmission direction form a set angle, so that the garlic heads are driven by the root transmission guide rail 2 to be transmitted horizontally along the support channel, and the garlic roots are tightened during the transmission along the second transmission direction;

[0093] Since the root clamping transmission guide rail 2 is retracted and clamps the garlic root, after the garlic head enters the positioning surface 12, as the positioning support frame 1 and the root clamping transmission guide rail 2 are transmitted, the distance between the bottom of the garlic head and the garlic root clamping position 2 becomes farther and farther, so that the garlic root is tightened during the backward transmission process. At this time, the garlic head is only subjected to the tension of the garlic root and the reaction force of the positioning support frame 1. Since there is no force above the garlic head, the bottom of the garlic head will be closely attached to the support surface of the positioning support frame 1 under the action of the tension of the garlic root, so that the center line of the garlic head and the support surface tend to be vertical, completing the positioning and correction of the garlic head before root cutting.

[0094] In this embodiment, since the garlic root has a certain toughness, when the clamping force of the clamping transmission guide rail is less than the tensile strength of the garlic root, the garlic root can slide relative to the clamping root transmission guide rail after being tensioned to avoid the garlic root from breaking; due to the set angle between the first transmission direction and the second transmission direction, the garlic head and the positioning surface slide relative to each other after the garlic root is fully tightened, so as to achieve the purpose of positioning and correction, thereby avoiding the situation in which the garlic head is damaged in the subsequent root cutting operation due to the feeding posture deviation such as the garlic head turning forward or leaning back or the shape of the garlic itself causing the center line to be not perpendicular to the cutting surface, that is, the cutting position deviation. Figure 9 shown.

[0095] Continue to see Figure 5 Under the joint action of the root clamping transmission guide rail 2 and the positioning support frame 1, the corrected garlic heads will continue to be transmitted horizontally along the support surface and reach the position of the first cutting member 13 for root cutting.

[0096] Specifically, the first cutting member 13 is parallel to the supporting surface and is arranged below the positioning surface 12, and is as close to the supporting surface as possible without affecting the operation of the first cutting member 13. At the same time, the positioning surface 12 is as thin as possible, so that the first cutting member 13 cuts as close to the garlic bottom plate as possible, so as to cut the garlic root cleanly.

[0097] In this embodiment, a pair of relatively thin disc cutters are used to perform counter-rotational motion or staggered cutting by the blades to complete the root cutting action. The distance between the blade edge of the first cutting member 13 and the intersection of the first transmission direction and the second transmission direction is appropriately adjusted according to the position of the root clamp and the angle between the positioning support frame 1 and the root clamp transmission guide rail 2 to ensure that the root cutting action is completed before the garlic root breaks and slides out of the root clamp transmission guide rail 2.

[0098] After the roots are cut, the garlic leaves the harvester under the action of inertia or other auxiliary transmission devices and is collected uniformly.

[0099] In other embodiments, the root clamping and conveying guide rail 2 can also be completed by cooperating with a tensioning mechanism in the prior art such as a conveyor belt or a chain.

[0100] In other embodiments, the track of the positioning support frame 1 can also be a stationary track made of smooth metal, plastic, glass, etc., but not limited to the above materials and having a certain anti-deformation effect.

[0101] In a preferred manner, in order to guide the roots of the garlic into the root clamping and conveying guide rail 2, a bracket 4 is provided on the machine frame. The bracket 4 is located at one end of the positioning support frame 1 and is sequentially arranged with the end of the positioning support frame 1 in the direction perpendicular to the support plane; the garlic is introduced into the positioning support frame 1 by the bracket 4 and continues to be conveyed in the horizontal direction for root cutting treatment; the bracket 4 can have a set distance from the positioning support frame 1, and this distance is set according to the situation of the garlic roots to facilitate the positioning support frame 1 to clamp the garlic roots; or the bracket 4 can be closely attached to the support surface of the positioning support frame 1.

[0102] The above embodiments achieve the cutting of the garlic roots, and the function of cutting the garlic stalks can also be added, and the specific method is as in Embodiment III.

[0103] Embodiment III:

[0104] On the basis of Embodiment I, a straw positioning frame 3 for clamping the garlic stalks and a second cutting member 33 are provided, and the garlic stalks are cut first and then the garlic roots are cut.

[0105] The straw positioning frame 3 has a clamping direction, and this clamping direction is parallel to the advancing direction of the garlic head; both the straw positioning frame 3 and the second cutting member 33 are fixed on the machine frame, and the straw positioning frame 3 drives the garlic to move on the machine frame in the clamping direction parallel to the support plane to clamp the garlic plants for operations such as cutting the stalks.

[0106] The straw positioning frame 3 includes: a transmission clamping rod 31, which conveys the crops by clamping the straw part;

[0107] A transmission pressing rod 32, which presses the crops on the positioning support frame 1, the bracket 4 or the root clamping and conveying guide rail 2 while conveying the crops; the transmission clamping rod 31 and the transmission pressing rod 32 are synchronously driven.

[0108] In this embodiment, taking the garlic plants being fed in by the bracket 4 as an example, see Figure 2 , the straw positioning frame 3 is arranged above the bracket 4, and the second cutting member 33 is located above the transmission pressing rod.

[0109] While the garlic plants are clamped and transmitted by the transmission clamp rod 31, the transmission pressure rod 32 provides pressure to press the garlic heads onto the bracket 4, so that the bottom of the garlic heads contacts the bracket 4, so that the bottoms of garlic heads of different sizes are basically in the same plane. The transmission clamp rod 31 and the transmission pressure rod 32 can be synchronously transmitted through a transmission belt, chain or other flexible transmission parts in conjunction with a tensioning mechanism.

[0110] During the transmission, the bracket 4 needs to move synchronously with the transmission clamp rod 31, the transmission pressure rod clamp 32 and the root clamp transmission guide rail 2, so that the garlic is transmitted backward in the state of "pressing up and supporting down".

[0111] In this embodiment, by making the bottoms of the garlic heads roughly in the same plane, ineffective clamping of the root clamping transmission guide rail is avoided.

[0112] Furthermore, after the garlic plants enter the root-clamping transmission guide rail 2, the second cutting member 33 disposed above the transmission pressure rod 32 cuts off the garlic stem 5, so that the garlic stem 5 is separated from the garlic head; the second cutting member 33 can be a disc knife, scissors, or a movable or fixed blade.

[0113] Since garlic actually sold requires a certain length of garlic stem to ensure that the garlic cloves will not loosen after drying, the second cutting member 33 is arranged above the transmission pressure rod 32 to keep a certain distance from the garlic head. Even if the garlic is in a tilted state at this time, the second cutting member 33 will not be damaged because a certain distance is maintained between the second cutting member 33 and the garlic head.

[0114] In other embodiments, the straw positioning frame 3 is arranged above the lifting portion 21 of the clamping root transmission guide rail 2, and the garlic stalks are cut after the garlic roots enter the clamping portion 22, see Figure 6 .

[0115] Similarly, the garlic stalks in the second embodiment are removed, and the stalk positioning frame 3 is arranged above the introduction part 11, such as Figure 7 As shown, the garlic stems and garlic heads can be separated before the garlic plants enter the positioning surface 12, thereby ensuring that no force is applied above the garlic heads when the roots are cut.

[0116] In this embodiment, the garlic stems are cut off before the garlic enters the positioning support frame 1, and the garlic is only transmitted by the root clamping transmission rail. At this time, the upper part of the garlic is not subjected to force and is in a free state. After entering the positioning support frame 1, since the bottom feature of the garlic itself is more gentle than the upper part of the garlic, there will be a larger contact area when it contacts the support surface. At this time, the tension of the garlic root and the force of the positioning support frame on the garlic are concentrated at one point. Under this force, the free state of the garlic will be automatically corrected, so that the bottom of the garlic is close to the positioning surface 12 to achieve positioning. In addition, since the garlic roots have been gathered and concentrated in advance, the gap in the middle of the positioning support frame 1 is relatively narrow, which can provide a larger support area while providing better protection for irregularly growing garlic.

[0117] Embodiment 4

[0118] The fourth embodiment of the present invention provides a device for first cutting the garlic roots and then cutting the garlic stalks. As Figure 8 shown, it includes: driving clamping rods 31, driving pressing rods 32 and positioning support frames 1 that are arranged in parallel and transmit synchronously. The root clamping transmission guide rail 2 is arranged below the positioning surface 12 of the positioning support frame 1, and the second cutting member 33 is arranged behind the first cutting member 13;

[0119] The garlic plants are fed in from the feeding part 11 and are transmitted on the supporting surface along the transmission direction. When the garlic plants enter the positioning surface 12, the garlic roots are clamped by the root clamping transmission guide rail 2, and the posture of the garlic plants is adjusted during the advancing process to complete the positioning; then the garlic roots are cut off by the first cutting member 13, and then, driven by the driving clamping rods 31, the garlic stalks are cut off by the second cutting member 33 at a preset position above the garlic bulbs.

[0120] In this embodiment, before cutting the garlic roots, the garlic stalks are in a released or semi-released state, that is, the dragging force of the garlic bulbs by the garlic stalks is less than the dragging force from the garlic roots, and the posture of the garlic plants can be corrected.

[0121] The present invention aims to protect a garlic root cutting device, which solves the problem of mechanized root cutting and straw removing for crops with similar shapes to garlic and onions. Among them, the root cutting function and the straw removing function can be separately set; it can cut the roots first and then remove the straws, or remove the straws first and then cut the roots; the present invention also solves the influence of the garlic plant shape and feeding posture on root cutting, does not damage the garlic body, and improves the qualification rate.
