Description

Technical Field

[0001] This utility model relates to the field of burdock harvesting, specifically an adjustable-depth lever-type burdock harvesting clamp with low damage. Background Technology

[0002] Burdock is an important economic crop that is both food and medicine. Its processed products are in high demand in the international market and have high economic value. The edible and medicinal parts of burdock are mainly its taproots. Its root system is well-developed, usually 40 to 80 centimeters or even longer, and grows vertically downwards, penetrating deep into the soil. It is straight, brittle and easily broken.

[0003] Currently, burdock harvesting mainly relies on manual labor. Harvesters typically use traditional farm tools such as shovels and hoes for digging. The usual procedure is as follows: first, manually determine the approximate location and depth of the burdock roots; then, use a shovel to dig a deep pit on one side of the burdock; and then attempt to pull the burdock out of the soil by hand or by pulling it out. However, because burdock roots are deep and the amount of soil that needs to be excavated is large, it is a great test of the harvesters' physical strength. During the digging and pulling process, tools such as shovels are very likely to injure, break, or scratch the burdock roots, causing inconvenience in harvesting. To address this, we propose an adjustable-depth lever-type low-damage burdock harvesting clamp. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-depth lever-type burdock harvesting clamp with low damage, in order to solve the problems mentioned in the background art and overcome its technical defects.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an adjustable-depth lever-type burdock low-damage harvesting clamp, including a harvesting cylinder, a first opening on the outer surface of the harvesting cylinder, a movable clamp inside the first opening, a support column fixedly connected to the top of the harvesting cylinder, a fixed handle fixedly connected to the top of the support column, a second opening on the outer surface of the support column, a handle movably connected inside the second opening via a pin, and one end of the handle being connected to the outer surface of the movable clamp.

[0006] Preferably, an elastic sheet is fixedly connected to the upper surface of the grip, and one end of the elastic sheet is connected to the bottom surface of the fixed handle.

[0007] Preferably, a first protective pad is fixedly connected to the outer surface of the fixed handle.

[0008] Preferably, a second protective pad is fixedly connected to the bottom surface of the grip, and the grip is sickle-shaped.

[0009] Preferably, the outer surface of the harvesting tube has a depth line.

[0010] Preferably, the bottom end of the harvesting cylinder is threaded with a ring-cutting mechanism, which is connected to the harvesting cylinder.

[0011] Preferably, the ring-cutting mechanism includes a connecting sleeve that is threadedly connected to the harvesting cylinder, a fixing sleeve is fitted on the outer surface of the connecting sleeve, anti-slip ribs are provided on the outer surface of the fixing sleeve, and a ring cutter is fixedly connected to the bottom end of the connecting sleeve.

[0012] Preferably, a protective pad is fixedly connected to one side of the movable clamp.

[0013] Compared with the prior art, the beneficial effects of this utility model include: The outer surface of this utility model harvesting cylinder is engraved with clear depth lines. Operators can easily screw the ring-cutting mechanism into the corresponding depth according to the average root length of different burdock varieties, ensuring that the ring cutter can reach the end of the burdock root and achieve complete harvesting in one go. Using the lever principle, by holding the fixed handle and pressing down the grip, the movable clamp can be driven to complete the clamping and lifting of the burdock root. This process transforms the heavy physical labor that originally required a lot of digging and bending over to pull out into a simple lever operation, which greatly reduces the labor intensity of harvesters and significantly improves harvesting efficiency.

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] According to one embodiment of the present invention, in conjunction with the appended drawings Figures 1-4 As shown.

[0017] Example 1 An adjustable-depth lever-type burdock harvesting clamp with low damage includes a harvesting cylinder 1. A first opening 3 is formed on the outer surface of the harvesting cylinder 1, and a movable clamping plate 4 is located inside the first opening 3. A support column 7 is fixedly connected to the top of the harvesting cylinder 1, and a fixed handle 9 is fixedly connected to the top of the support column 7. A second opening 6 is formed on the outer surface of the support column 7, and a handle 11 is movably connected to the inside of the second opening 6 via a pin 5. One end of the handle 11 is connected to the outer surface of the movable clamping plate 4. Using the lever principle, by gripping the fixed handle 9 and pressing down the handle 11, the movable clamping plate 4 can be driven to clamp and lift the burdock root. This process transforms the heavy physical labor that originally required extensive digging and bending over to pull the burdock into a simple lever operation, greatly reducing the labor intensity of harvesters and significantly improving harvesting efficiency.

[0018] Example 2 An elastic piece 10 is fixedly connected to the upper surface of the grip 11. One end of the elastic piece 10 is connected to the bottom surface of the fixed handle 9. A first protective pad 8 is fixedly connected to the outer surface of the fixed handle 9, and a second protective pad 12 is fixedly connected to the bottom surface of the grip 11. The grip 11 is sickle-shaped, which conforms to the human hand grip habit. The elastic piece 10 connects the grip 11 and the fixed handle 9 and can provide a rebound force after the grip 11 is released, so that the movable clamp 4 automatically resets, making the operation smoother and more effortless. At the same time, the first protective pad 8 and the second protective pad 12 increase the comfort of holding the hand and prevent the palm from being chafed during long-term operation.

[0019] Example 3 The outer surface of the harvesting cylinder 1 is provided with a depth line 13. With this clearly defined depth line, operators can easily screw the ring-cutting mechanism 2 into the appropriate depth based on the average root length of different burdock varieties. This ensures that the ring cutter 201 reaches the end of the burdock root, achieving a complete harvest in one go and avoiding multiple diggings or root residue caused by inaccurate depth judgment. The bottom end of the harvesting cylinder 1 is threadedly connected to the ring-cutting mechanism 2, which is in communication with the harvesting cylinder 1. The ring-cutting mechanism 2 includes a connecting sleeve 203 threadedly connected to the harvesting cylinder 1. A fixing sleeve 204 is fitted onto the outer surface of the connecting sleeve 203. The surface is provided with anti-slip ribs 202, and the bottom end of the connecting sleeve 203 is fixedly connected with a ring cutter 201. One side of the movable clamping plate 4 is fixedly connected with a protective pad 14. The ring cutter 201 at the bottom end of the ring cutting mechanism 2 cuts down first, which can accurately and vertically cut the soil around the burdock root to form a "soil tube" that matches the shape of the burdock root. This effectively isolates the burdock from the surrounding hard soil clods and gravel. Then, when the inner movable clamping plate 4 closes, it gently and firmly clamps the burdock root through the protective pad 14 on its side, avoiding the shovel damage, scratches and breakage that are easily caused by traditional shovel digging, and maximizing the integrity and commercial value of the burdock root.

[0020] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
