Description

Technical Field

[0001] This invention relates to the field of agricultural technology, and in particular to a special vegetable planting vine puller and its usage method. Background Technology

[0002] In recent years, the area under greenhouse vegetable cultivation has shown a significant upward trend. Compared with traditional open-field cultivation, greenhouse cultivation has advantages such as better heat preservation, stronger disaster resistance, and less damage from pests and diseases, significantly improving the quality and yield of vegetables. In terms of varieties, greenhouses mainly cultivate leafy vegetables, solanaceous vegetables, and cucurbits, with solanaceous vegetables and cucurbits accounting for a larger proportion due to their higher yield and economic benefits. Regarding cultivation methods, greenhouse cultivation primarily uses soil cultivation and substrate cultivation. Due to the small size and low ceiling of individual greenhouses, large machinery cannot easily enter. Therefore, the cleaning and hauling of solanaceous vegetables after planting still relies mainly on manual labor.

[0003] In existing technologies, the following two methods are mainly used when cleaning up the vineyards after the traditional planting cycle is completed:

[0004] (1) For soil-grown plants, the main stem is first cut off from the above-ground part, the above-ground parts of the plant are collected and transferred outdoors, and then the main roots are dug up with a hoe, collected again and transferred outdoors. This method is time-consuming and labor-intensive, with low labor efficiency. In addition, it is easy to pull up a large amount of soil from the roots, causing soil erosion and damage to the soil environment, which significantly affects the growth of the next crop.

[0005] (2) For substrate cultivation, the same treatment measures as for soil cultivation were adopted. On the other hand, most of the plants were directly pulled up by the roots for cleaning. However, this method easily brings up a large amount of substrate, which means that a large amount of substrate needs to be replenished before the next crop is planted. In addition, because the substrate is loose, the fibrous roots are also easily brought out, which significantly damages the root microenvironment of the substrate and is also not conducive to the connection of crop rotation.

[0006] In other words, existing vegetable cultivation technologies suffer from problems such as inconvenient operation, low labor efficiency, and poor protection.

[0007] Therefore, existing technologies have shortcomings and need to be improved and developed. Summary of the Invention

[0053] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of the present invention, a special seedling puller for vegetable planting includes: a fixed connecting rod 3, a hand handle 1, a fixed sleeve 4, a drive mechanism 20, a root puller 6, and a root pulling and cutting mechanism 10.

[0055] The handle 1 is preferably located at the upper end of the fixed connecting rod 3, and preferably has a gripping part for easy holding. The root puller 6 is fixedly located at the lower end of the fixed connecting rod 3, and the root puller 6 is designed with a hollow structure for easy insertion into the soil or substrate. The fixing sleeve 4 is fixedly located on the fixed connecting rod 3. Figure 1 As shown, the fixed sleeve 4 is arranged in two spaced intervals on the fixed connecting rod 3 to facilitate connection with the drive mechanism 20; the root pulling and cutting mechanism 10 is arranged inside the root puller 6 and is used to drive the plant root system to cut through the drive mechanism 20; the drive mechanism 20 is slidably arranged on the fixed connecting rod 3 and connected to the root pulling and cutting mechanism 10, and is used to drive the root pulling and cutting mechanism 10 to cut the plant root system through external force.

[0056] In this embodiment of the invention, the vegetable planting vine puller comprises a hand handle 1, a fixed connecting rod 3, and a root puller 6 connected in sequence. During use, the user first holds the hand handle 1, then inserts the root puller 6 of the vegetable planting vine puller into the soil or substrate at an angle downwards, directly facing the plant. The user then manually operates the drive mechanism 20 to pull upwards, and the pulling force of the drive mechanism 20 drives the root-pulling and cutting mechanism 10 to cut the plant's root system, completing the vine pulling operation. Thus, the vegetable planting vine puller of this invention can quickly and easily remove plants in one go, avoiding soil or substrate loss, maintaining the root microenvironment, and can be mass-produced, operated quickly, and reused, providing convenience for users.

[0057] Optionally, the vegetable planting vine puller described in this embodiment of the invention, such as... Figure 1 , Figure 2 and Figure 4 As shown, the drive mechanism 20 includes: a power arm 2, a power connecting rod 5, and a transmission shaft 8 connected in sequence. The transmission shaft 8 is slidably disposed on a shaft fixing sleeve 7, and the shaft fixing sleeve 7 is fixedly disposed within the root puller 6. In this embodiment, as... Figure 1 As shown, the fixed sleeves 4 are respectively provided at the upper and lower parts of the fixed connecting rod 3. The power connecting rod 5 is slidably sleeved in the fixed sleeves 4 at the upper and lower parts of the fixed connecting rod 3, so that the power connecting rod 5 can be pulled up and down in the fixed sleeves 4. The structure is simple and the operation is convenient.

[0058] like Figure 4 As shown, the power arm 2 is located at the upper end of the power connecting rod 5, and the power arm 2 is provided with a gripping part 21 for easy hand gripping. The lower end of the power connecting rod 5 is connected to the drive shaft 8. One end of the drive shaft 8 is connected to the power connecting rod 5, and the other end of the drive shaft 8 is connected to the root-pulling and cutting mechanism 10. The shaft fixing sleeve 7 is fixedly installed inside the root puller 6. The shaft fixing sleeve 7 is provided with a shaft hole, through which the drive shaft 8 passes and is connected to the root-pulling and cutting mechanism 10. The drive shaft 8 is movably installed inside the shaft fixing sleeve and can move up and down relative to the shaft fixing sleeve. When the drive mechanism 20 of this invention is used, the user can hold the handle 1 with one hand, such as... Figure 1 As shown, hold the power arm 2 by hand and pull it upward to drive the power connecting rod 5 to move upward. The upward pulling force of the power connecting rod 5 drives the transmission shaft 8 connected to the power connecting rod to move upward, thereby driving the root-pulling and cutting mechanism 10; optionally, as Figure 1 As shown, the hand handle 1 and the power arm 2 are arranged parallel to each other vertically, which makes it convenient to hold the parallel hand handle 1 and the power arm 2 with one hand, so that the power arm 2 moves closer to the hand handle 1 and drives the power connecting rod 5 to pull upward.

[0059] Optionally, the vegetable planting vine puller described in the embodiments of the present invention, such as... Figure 2 and Figure 4 As shown, the root-pulling and cutting mechanism 10 includes a blade 9 and a connecting rod 11. The connecting rod 11 is movably connected to the transmission shaft 8 of the drive mechanism. The blade 9 is movably disposed within the root puller 6. The blade 9 is connected to the connecting rod 11. The drive mechanism drives the connecting rod 11 to rise, and the rising of the connecting rod 11 causes the blade 9 to close horizontally, cutting off the plant root system.

[0060] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the power arm 2 is pulled upward, the power connecting rod 5 moves upward, which in turn drives the transmission shaft 8 to rise. The transmission shaft 8 then drives the connecting rod 11 to move, which in turn drives the blade 9 to close horizontally, cutting off the plant roots. The operation is simple and convenient. Thus, the vegetable planting special seedling puller of this invention can complete the seedling pulling operation in one go. It has the characteristics of wide applicability, simple operation, and high labor efficiency.

[0061] Optionally, such as Figure 2 and Figure 3 As shown, the end of the blade 9 is bent horizontally to facilitate root entry into the blade, allowing for horizontal cutting after root entry; preferably, the connection between the blade 9 and the connecting rod 11 is detachable for easy replacement of the blade; for example, as Figure 3 As shown, the blades can be configured to include a first blade 91 and a second blade 92 arranged symmetrically. The first blade 91 and the second blade 92 are crossed together in the middle, and the ends of the first blade 91 and the second blade 92 are bent in a horizontal direction. In this way, the upward pulling force driven by the transmission shaft 8 drives the connecting rod 11 to move, thereby driving the blades 9 to close horizontally. The first blade 91 and the second blade 92 can be closed horizontally with very easy force to cut the plant roots. The operation is simple and convenient.

[0062] Optionally, the vegetable planting vine puller, such as Figure 1 As shown, the root puller 6 is a cylindrical metal structure root puller 6. The cylindrical metal structure root puller 6 has a simple, rigid, and durable structure. The end of the root puller 6 is a conical structure, which makes it easy to insert into the soil. The front part of the cylindrical metal structure root puller 6 is provided with a hollow structure 61. When in use, the conical structure at the end of the root puller 6 is inserted into the soil or substrate at an angle downwards, and the hollow structure 61 is turned upwards to make it easy for the main stem of the vegetable plant to be exposed through the hollow structure 61. This makes it easy for the end of the root puller 6 to be inserted into the vegetable root at an angle without damaging the main stem of the vegetable plant, which provides convenience for the user.

[0063] Optionally, the vegetable planting vine puller described in the embodiments of the present invention, such as... Figure 1 As shown, the handle 1 has an internal metal structure, which can increase the hardness of the handle 1 and extend its service life. The outer layer of the handle 1 is covered with a plastic kit, which makes it easy for users to hold without hurting their hands. The fixed connecting rod 3 is a metal fixed connecting rod, which can increase the hardness and service life of the metal fixed connecting rod. The upper part of the metal fixed connecting rod 3 is connected to the handle 1, and the lower part is connected to the root puller 6. The handle 1, the metal fixed connecting rod 3, and the root puller 6 are connected in sequence, which is convenient to carry and simple to operate.

[0064] Optionally, in this embodiment of the invention, the power arm 2 is a metal structure power arm 2, with an outer plastic sleeve; the metal structure power arm can improve the rigidity of the power arm 2 and extend its service life, while the outer plastic sleeve makes it convenient for the user to hold. The power connecting rod 5 is a metal structure power connecting rod, which can improve the rigidity of the power connecting rod 5 and extend its service life. The power connecting rod 5 is movably connected through the fixed sleeve 4, and the power connecting rod 5 can move up and down relative to the fixed sleeve. The upper part of the power connecting rod 5 is connected to the power arm 2, and the lower part is connected to the drive shaft 8.

[0065] The vegetable planting puller described in this embodiment of the invention may optionally have a fixed connecting rod 3 with a length of 1m, which is convenient for adult operation. The power connecting rod 5 has a length of 95cm; the length of the power connecting rod 5 is slightly shorter than the length of the fixed connecting rod 3, which facilitates the parallel vertical arrangement of the handle 1 and the power arm 2. This allows for easy one-handed gripping of the parallel handle 1 and power arm 2, causing the power arm 2 to move closer to the handle 1 and pull the power connecting rod 5 upward.

[0066] Optionally, the root puller 6 has a diameter of 15cm and a total length of 20cm, which is just right for inserting most vegetable roots. The conical structure is 5cm high, and the angle between the circle and the vertical direction of the conical structure is 45 degrees, which facilitates oblique insertion into the vegetable roots. The arc length of the hollow structure 61 is 10cm, that is, the length of the hollow structure 61 is 10cm. This length can ensure that the main stem of the vegetable can be inserted and that the bottom of the root puller 6 can be inserted obliquely into the vegetable root, so as to remove the main root of the plant at a fixed point, preserve the fibrous root system, and effectively protect the root microbial environment.

[0067] Other options, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the specific application embodiment of the present invention, a vegetable planting vine pulling device includes:

[0068] The device comprises a handle 1, a power arm 2, a fixed connecting rod 3, a fixed sleeve 4, a power connecting rod 5, and a root puller 6. The handle 1 and power arm 2 are both made of metal with an outer plastic sleeve for easy handling. The fixed connecting rod 5 is preferably 1m long, and the power connecting rod 6 is preferably 95cm long. The root puller 6 is made of metal, has a cylindrical structure, a preferred diameter of 15cm, and a preferred total length of 20cm. The end of the root puller 6 has a conical structure, 5cm high, with a 45-degree angle between the circle and the vertical direction, facilitating quick insertion into the soil or substrate surrounding the roots. The cylindrical structure of the root puller 6 has a hollowed-out front section with an arc length of 10cm, allowing the plant stem and roots to pass through. The power connecting rod 5 and the root puller 6 are detachably connected, including through a socket or threaded connection; other detachable connections are also within the scope of this solution.

[0069] like Figure 2 , Figure 3 As shown, the shaft fixing sleeve 7, the drive shaft 8, and the blade 9 are disposed within the root puller 6. The root puller 6 is made entirely of metal, preferably stainless steel. The shaft fixing sleeve 7 has a shaft hole inside, through which the drive shaft passes and connects to the root pulling and cutting mechanism. The drive shaft is movably disposed within the shaft fixing sleeve and can move up and down relative to the shaft fixing sleeve. The end of the blade 9 is bent horizontally, allowing for horizontal cutting after the root system enters. The blade height is located at the junction of the cylindrical and conical structures at the lower end of the root puller 6. The blade 9 can be flexibly disassembled, connected, and replaced; all types of detachable connections are within the protection scope of this solution.

[0070] Working principle:

[0071] like Figure 5 and Figure 6 As shown, first hold the handle 1 with the root puller facing the plant, and insert it diagonally downwards into the soil or substrate, allowing the plant stem and roots to pass through the cutout until the main root is above the blade 9. At the same time, squeeze the power arm 2 upwards to lift it. The power arm 2 drives the power connecting rod 5 to rise, which in turn drives the transmission shaft 8 to rise. Then, the transmission shaft 8 drives the connecting rod 11 to move, which in turn drives the blade 9 to close horizontally, cutting the plant roots and completing the pulling operation. Afterwards, release the power arm 2, and the blade will automatically return to its original position for the next repetition.

[0072] Based on the above embodiments, such as Figure 7 As shown, the present invention also provides a method for controlling the root pulling of a vegetable planting vine puller as described in any of the preceding claims, comprising the following steps:

[0073] Step S100: Straighten the vegetable plant and insert the root puller of the vegetable planting special puller obliquely into the root of the vegetable plant by holding the handle.

[0074] Step S200: When all the main roots of the vegetable plant have entered the upper part of the root puller blade position, operate the power arm to lift the power arm upward, drive the power connecting rod upward, and drive the transmission shaft to move upward relative to the shaft fixing sleeve through the upward force of the power connecting rod.

[0075] Step S300: The upward motion transmission linkage of the transmission shaft drives the blades to close horizontally, cutting the plant roots. Lifting the plant completes the pulling operation. The specifics are as described above.

[0076] As can be seen, the vegetable planting vine puller disclosed in this invention includes a handle, a power arm, a fixed connecting rod, a fixed sleeve, a power connecting rod, a root puller, a shaft fixing sleeve, a transmission shaft, and a blade. The handle is a metal structure covered with a plastic sleeve. The handle is connected to the root puller via the fixed connecting rod. The power arm is also a metal structure covered with a plastic sleeve. The power arm is connected to the root puller via the power connecting rod, which is fixed by the fixed sleeve. The root puller has a cylindrical structure with a tapered end. The front of the cylindrical structure is hollowed out. The root puller contains a shaft fixing sleeve, a transmission shaft, and a blade. The shaft fixing sleeve connects to the power connecting rod. The transmission shaft is connected to the shaft fixing sleeve, and the blade is connected to the transmission shaft. The end of the blade is bent horizontally. To use, hold the vegetable plant with one hand and insert the handle at an angle into the root of the vegetable with the other. When the main root is fully inside the blade position of the root puller, grip the power arm and lift upwards. The blade closes and cuts the root system, lifting the plant to complete the pulling operation, achieving the purpose of rapid vine pulling. It is suitable for greenhouses or small vegetable plots where large agricultural equipment is difficult to operate, such as soil cultivation or substrate cultivation, where vine pulling is difficult, there is significant loss of soil or substrate around the roots, and labor efficiency is low. It has good technical effect, convenient operation, and is simple to use.
