Description

Technical Field

[0001] This invention relates to a garlic root-cutting device, belonging to the field of agricultural machinery technology. Background Technology

[0002] China is one of the world's largest garlic-growing countries, and garlic deep processing has become an industry. In the early stages of garlic deep processing, the rootstock at the bottom of the garlic cloves needs to be removed, followed by peeling to meet the requirements of subsequent production processes. Currently, the mechanization level of garlic root removal in China is low, with manual processing being the primary method. This is not only inefficient and results in significant garlic loss and high labor costs, but also poses a safety hazard of hand injuries to operators. While some technicians have designed devices that can mechanically cut the garlic roots, these existing devices generally suffer from incomplete root removal, causing considerable damage to the garlic cloves, high production costs, and difficulties in large-scale application. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide a garlic root cutting device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The garlic root-cutting device includes: a central shaft, a fixing mechanism, a first drive mechanism, several positioning cups, a root-cutting blade, and an outer cylinder;

[0006] The fixing mechanism is cylindrical and has a first end face, a second end face, and a main surface. Both the first and second end faces are circular. The main surface is located between the first and second end faces and has a first discharge port. The center of the first and second end faces is passed through by the central shaft, which is rotatably connected to the central shaft. The rotatable connection refers to the connection that allows the fixing mechanism to rotate about the central shaft.

[0007] The first driving mechanism is connected to the fixed mechanism and drives the fixed mechanism to rotate about the central axis.

[0008] The positioning cup includes a first cup body, a second cup body, and an elastic element; the first cup body is open at both ends and has a first accommodating space inside; the second cup body is open at both ends and has a second accommodating space inside; the first cup body is located above the second cup body, and the first accommodating space and the second accommodating space communicate with each other; the elastic element has its two ends connected to the first cup body and the second cup body respectively in its extension and contraction direction; the lower opening diameter of the first cup body and the upper opening diameter of the second cup body are both larger than the diameter of a garlic clove, and the lower opening diameter of the second cup body is larger than the diameter of the garlic root but smaller than the diameter of the garlic clove; the total height of the first cup body and the second cup body is smaller than the height of the garlic clove; the positioning cup is vertically disposed on the main surface;

[0009] The outer cylinder includes a uniform radius semi-cylinder and a variable radius semi-cylinder, the uniform radius semi-cylinder and the variable radius semi-cylinder being arranged opposite to each other; the top of the outer cylinder has a feed port; the outer cylinder has a second discharge port, the second discharge port being located at the lower part of the outer cylinder; the outer cylinder is sleeved outside the fixing mechanism, and its two end faces are passed through by the central shaft and are statically connected to the central shaft;

[0010] The root cutting blade is located inside the fixing mechanism, on the side where the variable radius semi-cylinder is located, above the second discharge port, and connected to the central axis; the plane where the root cutting blade is located is perpendicular to the positioning cup.

[0011] The root-cutting blade is located at the minimum radius of the variable-radius semi-cylinder; the minimum radius of the variable-radius semi-cylinder forms a first angle with the horizontal plane; the first angle is greater than 30° and less than 90°. The first angle can be between 45° and 80°.

[0012] The distance between the root cutting blade and the bottom of the positioning cup perpendicular to it is 2±0.5mm.

[0013] It also includes a second drive mechanism; the root cutter includes a blade and a blade holder; the blade holder is statically connected to the central shaft and rotatably connected to the blade; the second drive mechanism is connected to the blade and drives the blade to rotate in its plane. The number of blades is two or more.

[0014] The fixing mechanism includes multiple fixing rings and multiple fixing members; the multiple fixing rings are arranged in parallel between the first end face and the second end face, and are arranged concentrically; the multiple fixing members connect the multiple fixing rings into a whole to form the main surface; the gap between the fixing members, the fixing rings and the positioning cup is the first discharge port.

[0015] The feed inlet is elongated and its width is greater than the diameter of a garlic clove.

[0016] Along the length of the fixing mechanism, the plurality of positioning cups are arranged in a straight line.

[0017] It also includes a support; the two ends of the central shaft are connected to the support.

[0018] The beneficial effects of this invention are:

[0019] The rotating fixed mechanism drives the positioning cup to rotate, while the central shaft, root-cutting blade, and outer cylinder remain stationary. When the positioning cup rotates to the feed inlet located at the top of the outer cylinder, garlic cloves fall from above the feed inlet, falling freely under gravity. Since the weight of the garlic root is greater than the weight of the garlic clove itself, the root will face downwards during free fall. After the garlic falls into the positioning cup, as the fixed mechanism rotates, the distance between the fixed mechanism and the variable-radius semi-cylinder decreases, and the garlic cloves inside the positioning cup are then squeezed by the variable-radius semi-cylinder, causing the root to protrude downwards from the bottom of the positioning cup, thus completing the positioning of the garlic. When the garlic root rotates to the root-cutting blade, the blade cuts off the root, and the cut garlic falls out from the upper hollow cylinder through the lower opening of the outer cylinder. Compared with existing root-cutting mechanisms, this device has a simple structure, low production cost, and completely cuts the root without damaging the garlic cloves.

[0020] The overall design is cylindrical, and the garlic roots are cut off during the rotation process. It occupies little space and can be effectively used in conjunction with garlic harvesting devices.

[0021] The outer cylinder adopts a variable radius semi-cylinder design. By changing the radius of the outer cylinder, the distance between the outer cylinder and the fixing mechanism changes, thereby compressing the positioning cup and causing the garlic root to protrude, providing the necessary conditions for root cutting.

[0022] The root-cutting blade is positioned at the minimum radius of the variable-radius semi-cylinder. At this minimum radius, the garlic is subjected to maximum compression, allowing the garlic root to fully protrude from the bottom of the positioning cup, thus completely removing the root. Furthermore, after passing through the root-cutting blade, as the fixing mechanism rotates, the radius of the outer cylinder increases. The garlic with its root cut off is no longer compressed by the outer cylinder, preventing damage and ensuring the garlic's integrity.

[0023] When the first included angle is between 45° and 80°, the minimum radius of the variable radius semi-cylinder is located in the lower half of the outer cylinder. The root-cutting knife is set in the lower half of the outer cylinder, which is closer to the second discharge port, making it easier for the cut garlic roots to be thrown out from the second discharge port.

[0024] Compared to a stationary blade design, a rotating blade design can more thoroughly remove the garlic root, meaning that the garlic root removal rate is higher. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention.

[0034] A garlic root-cutting device includes: a central shaft 1, a fixing mechanism, a first driving mechanism, several positioning cups 9, a root-cutting blade 10, and an outer cylinder 2; the fixing mechanism is cylindrical and has a first end face, a second end face, and a main surface; both the first and second end faces of the fixing mechanism are circular, and the main surface of the fixing mechanism is located between the first and second end faces, with a first discharge port on the main surface; the central shaft 1 passes through the center of the first and second end faces and is rotatably connected to the central shaft 1; the rotatable connection refers to the connection that allows the fixing mechanism to rotate about the central shaft 1; the first driving mechanism is connected to the fixing mechanism and drives the fixing mechanism to rotate about the central shaft 1; the positioning cups 9 include a first cup body, a second cup body, and an elastic element; the first cup body is open at both ends and has a first accommodating space inside; the second cup body is open at both ends and has a second accommodating space inside; the first cup body is located above the second cup body, and the first and second accommodating spaces communicate with each other; An elastic element has two ends connected to a first cup body and a second cup body respectively in its extension and contraction direction; the lower opening diameter of the first cup body and the upper opening diameter of the second cup body are both larger than the diameter of the garlic, and the lower opening diameter of the second cup body is larger than the diameter of the garlic root but smaller than the diameter of the garlic; the total height of the first cup body and the second cup body is smaller than the height of the garlic; the positioning cup 9 is vertically set on the main surface; the outer cylinder 2 includes a uniform radius semi-cylinder 2-1 and a variable radius semi-cylinder 2-2, which are arranged opposite to each other; the top of the outer cylinder 2 has a feed port, and the outer cylinder 2 has a second discharge port, which is located at the lower part of the outer cylinder 2; the outer cylinder 2 is sleeved outside the fixing mechanism, and its two end faces are passed through by the central shaft 1 and are statically connected to the central shaft 1; the root cutting knife 10 is located inside the fixing mechanism, on the side where the variable radius semi-cylinder 2-2 is located, above the second discharge port, and connected to the central shaft 1; the plane where the root cutting knife 10 is located is perpendicular to the positioning cup 9.

[0035] The fixing mechanism rotates around the central shaft 1, which can be achieved as follows: Two bearings are mounted on the central shaft 1, with the two bearings acting as the driving axis. The two bearings pass through the centers of the first and second end faces, respectively, and are statically connected to the first and second end faces of the fixing mechanism. One of the bearings is connected to the driving mechanism, which drives the bearing to rotate around the central shaft 1, thereby causing the fixing mechanism to rotate around the central shaft 1. The bearings are statically connected to the first and second end faces to ensure that there is no relative movement between the bearings and the first and second end faces; specifically, this connection can be fixed or detachable.

[0036] The main surface of the fixing mechanism can adopt the following structure: It includes multiple fixing rings 6 and multiple fixing members; the multiple fixing rings 6 are arranged parallel to each other between the first end face and the second end face, and are concentrically aligned; the multiple fixing members connect the multiple fixing rings 6 into a whole, forming the main surface; the gap between the fixing members, the fixing rings 6 and the positioning cup 9 is the first discharge port. The fixing members and the fixing rings 6 can be fixedly connected. When both the fixing members and the fixing rings 6 are made of steel, they can be connected by welding. The fixing members can be long rods or strips; their length is approximately equal to the length of the fixing mechanism. The long rods or strips of fixing members are perpendicular to the fixing rings 6, connected to all the fixing rings 6, and form a crisscrossing grid with the fixing rings 6; making the main surface of the fixing mechanism grid-like.

[0037] The first and second end faces of the fixing mechanism can be formed by a strip or rod-shaped connector. One end of the connector is connected to the fixing member or the fixing rings 6 located at both ends, and the other end is statically connected to the bearing. Alternatively, the first and second end faces of the fixing mechanism can be formed by a fixing disc. The outer edge of the fixing disc is connected to the fixing member or the fixing rings 6 located at both ends, and the center of the fixing disc is passed through by the bearing and statically connected to the bearing. The fixing disc and the fixing member or the fixing rings 6 located at both ends can be detachably connected; specifically, the fixing member can protrude from the fixing rings 6 located at both ends, and the outer edge of the fixing disc has a hole that matches the fixing member protruding from the fixing rings 6. The connection between the fixing disc and the fixing member is completed by installing the fixing member protruding from the fixing rings 6 into the hole. The fixing member can be a threaded connecting rod 4.

[0038] The first drive mechanism can be formed by connecting a V-belt pulley 8 to an external drive motor. The shaft of the external drive motor and the bearing can be connected by a motor belt. When the shaft of the external drive motor rotates, it drives the bearing to rotate via the motor belt, and the bearing drives the fixed mechanism to rotate.

[0039] The positioning cup 9 is vertically positioned on the main surface, and the lower opening of the second cup body of the positioning cup 9 is not obstructed by the main surface. Specifically, mounting holes can be made on the main surface, through which the second cup body of the positioning cup 9 passes. The side of the second cup body of the positioning cup 9 is connected to the main surface of the fixing mechanism, and the lower opening of the second cup body is flush with or protrudes from the inner surface of the fixing mechanism. When the main surface is formed by a fixing ring 6 and multiple fasteners, the side of the second cup body of the positioning cup 9 is connected to the fixing ring 6 and the fasteners. Specifically, the grid formed by the intersection of the fixing ring 6 and the fasteners is tangent to the second cup body of the positioning cup 9. Along the circumferential direction of the fixing ring 6, there can be more than one grid spaced between the positioning cups 9. In the length direction of the fixing mechanism, the multiple positioning cups 9 are linearly distributed. The elastic element can be a spring 9-2. The number of elastic elements can be two or more, for example, three; the three springs 9-2 are evenly distributed.

[0040] The root-cutting blade 10 is positioned within the space between the fixing mechanism and the central axis 1. The plane of the root-cutting blade 10 being perpendicular to the positioning cup 9 means that when the positioning cup 9 is rotated to directly above the root-cutting blade 10, the plane of the root-cutting blade 10 is perpendicular to the central axis 1 of the positioning cup 9. When the positioning cup 9 is placed vertically, and the bottom end of the second cup body of the positioning cup 9 is flat, when the positioning cup 9 is rotated to directly above the root-cutting blade 10, the plane of the root-cutting blade 10 is parallel to the bottom end of the second cup body of the positioning cup 9. The distance between the root-cutting blade 10 and the bottom end of the positioning cup 9 perpendicular to it is 2 ± 0.5 mm; that is, when the positioning cup 9 is rotated to directly above the root-cutting blade 10, the distance between the root-cutting blade 10 and the bottom end of the positioning cup 9 perpendicular to it is 2 ± 0.5 mm.

[0041] The root cutting blade 10 is located on one side of the variable radius semi-circular cylinder 2-2. Specifically, it can be located at the minimum radius of the variable radius semi-circular cylinder 2-2; the minimum radius of the variable radius semi-circular cylinder 2-2 has a first angle with the horizontal plane; the first angle is greater than 30° and less than 90°. The first angle can be equal to 45°-80°.

[0042] The root cutting blade 10 may specifically include a blade 10-2 and a blade holder 10-1. The blade 10-2 is connected to the central shaft 1 via the blade holder 10-1. Specifically, the blade holder 10-1 may be U-shaped, with both ends statically connected to the central shaft 1 (e.g., fixedly connected), and the blade 10-2 positioned at the bottom. The blade 10-2 and the blade holder 10-1 may be statically or dynamically connected. When the blade 10-2 and the blade holder 10-1 are dynamically connected, a second drive mechanism should also be provided; the second drive mechanism is connected to the blade 10-2 and drives the blade 10-2 to rotate within its plane. Specifically, the second drive mechanism may include: a second motor 10-5, a rotating shaft, and a gear 10-4. The rotating shaft and gear 10-4 are mounted on the blade holder 10-1. The rotating shaft is perpendicular to the plane of the blade 10-2, positioned below the blade 10-2, with one end statically connected to the blade 10-2 and the other end rotatably connected to the blade holder 10-1. The gear 10-4 is fitted onto the rotating shaft and statically connected to it. The gear 10-4 cooperates with the second motor. The second motor 10-5 drives the gear 10-4 to rotate, the gear 10-4 drives the rotating shaft to rotate, and the rotating shaft drives the blade 10-2 to rotate. At this time, there can be two or more blades 10-2; one blade 10-2 can be mounted on the blade holder 10-1. The shape of the blade 10-2 can be a cross-shaped pattern as shown in the figure. Compared to the static connection between the blade 10-2 and the blade holder 10-1, the rotatable connection between the blade 10-2 and the blade holder 10-1 allows for better and more thorough removal of the garlic root.

[0043] The outer cylinder 2 is an approximately cylindrical structure formed by a uniform radius semi-cylindrical cylinder 2-1 and a variable radius semi-cylindrical cylinder 2-2. It has an internal approximately cylindrical accommodating space. The central shaft 1, except for its two ends, along with the fixing mechanism, positioning cup 9, and root-cutting knife 10, are all housed within this accommodating space. As shown in the figure, viewed from the front, one side is the uniform radius semi-cylindrical cylinder 2-1, its center located on the central axis; the other side is the variable radius semi-cylindrical cylinder 2-2. The feed inlet can be elongated, with a width greater than the diameter of a garlic clove. The second discharge outlet can be located at the bottom of the outer cylinder 2; the second discharge outlet can also be elongated, with a width greater than the diameter of a garlic clove.

[0044] A support bracket 3 can be installed to support the main structure of the garlic root cutting device. The two ends of the central shaft 1 are connected to the support bracket 3. Example

[0045] A garlic root-cutting device as shown in the figure comprises, from the inside out, a central shaft 1, a root-cutting blade 10, a fixing ring 6, a fixing sleeve 5, a fixing plate 7, a V-belt pulley 8, a positioning cup 9, a threaded connecting rod 4, an outer cylinder 2, and a bracket 3. The central shaft 1 is installed on the innermost side and serves to fix the root-cutting blade 10, the outer cylinder 2, and the bracket 3.

[0046] The central shaft 1 is a rod symmetrical at both ends. The two ends are square rods, which restrict the rotation of the outer cylinder 2 and play a fixing role. The thinner part in the middle is used to install the root cutting knife 10, and the thicker cylindrical sections on both sides can install bearings to install the fixing sleeve 5.

[0047] The fixed sleeve 5 is mounted on the thicker cylindrical sections at both ends of the central shaft 1 via bearings. The fixed sleeve 5 has an annular array of threaded holes, which can be connected to the threaded connecting rod 4. The threaded connecting rod 4 further connects to the fixed ring 6 and the fixed plate 7.

[0048] The inner side of the fixing ring 6 has a ring array of threaded holes, which are distributed at large intervals through the threaded connecting rod 4. Its function is to fix the positioning cup 9. In this embodiment, there are three fixing rings 6.

[0049] The fixing plate 7 is modified from the fixing ring 6. Each fixing plate 7 has a threaded hole on its outer edge. The three fixing plates 7 can form an irregular fixing ring with three notches under the action of the threaded connecting rod 4, so as to fix the positioning cup 9. The irregular fixing rings are distributed among the fixing rings 6 with small gaps. The distance between the irregular fixing ring closest to the fixing ring is equal to the gap between the irregular fixing rings.

[0050] The threaded connecting rod 4 is a relatively long threaded rod used to connect the fixing sleeve 5, the fixing ring 6, and the fixing plate 7 to form a fixing mechanism. The gaps between the fixing plates 7, the fixing ring 6, the threaded connecting rod 4, and the positioning cup 9 allow the cut garlic roots to fall out of the fixing mechanism.

[0051] The positioning cup 9 has openings at both ends and its main body consists of an upper hollow cylinder 9-1, a lower hollow cylinder 9-3, an upper ring, a lower ring, and three elastic springs 9-2. The diameter of the upper ring is 2-3 mm larger than the average diameter of the garlic clove, approximately 49 mm. This ensures the garlic clove falls safely into the positioning cup 9 under gravity. The lower ring is 1-2 mm larger than the diameter of the garlic root, approximately 40 mm, ensuring the garlic clove stops moving freely inside. The positioning springs 9-2 inside the cup are compression springs with good elasticity and stiffness. They are selected from CNM0.2×2×10×14, with an outer diameter of 2 mm, an inner diameter of 1.6 mm, a free length of 10 mm, a total of 14 coils, a maximum height of 4.12 mm, and are made of carbon steel. When subjected to the squeezing force of the outer cylinder 2, the springs 9-2 compress, and the resulting pressure presses against the outer cylinder 2, achieving precise positioning. The positioning cup 9 is fixed by welding in the gap between the fixed sleeve 5, the fixed disc, and the fixed ring 6, and its distribution is a ring array.

[0052] The outer cylinder 2 is welded together from a uniform radius semi-cylinder 2-1 and a variable radius semi-cylinder 2-2. After welding, one end of the outer cylinder 2 has a large circular hole, which serves as a transition gap for the triangular belt pulley 8 to drive the rotation of the fixed circular sleeve 5 on one side. The other end has a square hole 3-1 for mounting the central shaft 1, so that the outer cylinder 2 can remain stable when the triangular belt pulley 8 drives the internal structure to rotate. Viewed from the front, one side is a uniform radius semi-cylinder 2-1, and the other side is a variable radius semi-cylinder 2-2. This design allows the positioning cup 9 to be compressed on the variable radius semi-cylinder 2-2 side during rotation, causing the spring 9-2 of the positioning cup 9 to elastically deform, thereby positioning the garlic. The outer cylinder 2 has elongated holes at the top and bottom; the top elongated hole allows the garlic to fall in, and the bottom elongated hole allows the chopped garlic to fall out.

[0053] The V-belt pulley 8 is welded to a fixed circular sleeve 5 and installed on the side of the outer cylinder 2 with a circular hole. When the V-belt pulley 8 is driven to rotate by external power, the V-belt pulley 8 drives the fixed circular sleeve 5 to rotate. Under the action of the threaded connecting rod 4, the fixed ring 6, the fixed circular piece 7 and the other fixed circular sleeve 5 are driven to rotate together, thereby driving the positioning cup 9 to rotate.

[0054] The root cutting blade 10 is welded to the central shaft 1, specifically at a 45° angle to the horizontal plane on the lower part of one side of the variable radius semi-cylinder 2-2. At this location, the radius of the variable radius semi-cylinder 2-2 is at its smallest, and the distance between the root cutting blade 10 and the bottom of the material cup at this position is approximately 2mm. The root cutting blade 10 is composed of a blade 10-2, a blade holder 10-1, a gear 10-4, a gear cover, and a second motor 10-5. The second motor 10-5 drives the central gear 10-4 to rotate, which in turn drives the other gears 10-4 to rotate. The blade 10-2 is mounted on the gear 10-4, which in turn drives the blade 10-2 to rotate. When the second motor 10-5 is energized, one side of the blade 10-2 rotates clockwise, and the other side rotates counterclockwise. Because the cutting tools used need to rotate at a high speed of 1500r / min and need to have good wear resistance, corrosion resistance, rigidity and hardness, high-speed steel was selected as the raw material for the 10-2 cutting tool and the 10-4 gear.

[0055] The bracket 3 is installed on the central shaft 1 through the square holes 3-1 on both sides. The two small supports 3-2 on the two connecting rods in the middle of the bracket 3 are used to support the outer cylinder 2, so that the outer cylinder 2 is subjected to uniform force. The bracket 3 can be placed on the ground or other flat surfaces and can play a good role in fixing and supporting.

[0056] In this embodiment, when the V-belt pulley 8 drives the fixed sleeve 5 on one side of the outer cylinder 2 to rotate, the threaded connecting rod 4 on the fixed sleeve 5 drives the other fixed rings 6, fixed plates 7, and fixed sleeve 5 to rotate, which in turn drives the positioning cup 9 to rotate. Since the weight of the garlic root is greater than the weight of the garlic, when the garlic falls freely, the garlic root will face down. When the garlic falls into the positioning cup 9, the outer cylinder 2 then squeezes the upper hollow cylinder 9-1, and the upper hollow cylinder 9-1 compresses the spring 9-2, so that the garlic root to be cut out is exposed from the lower hollow cylinder 9-3, completing the positioning of the garlic. When the garlic root rotates to the root-cutting knife 10, the blade 10-2 of the root-cutting knife 10 rotates to cut off the garlic root, and the cut garlic falls out from the upper hollow cylinder 9-1 through the lower opening of the outer cylinder 2.

[0057] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
