Description

Technical Field

[0001] The invention belongs to the technical field of vegetable planting, and in particular relates to a vegetable seedling transplanter based on mechanical balance and a seedling transplanting method thereof. Background Art

[0002] Focusing on national economy and people's livelihoods has always been a top priority in technological research and development. As we all know, China is a populous country, and the importance of solving the food source problem for 1.4 billion people is unquestionable. Vegetables are a common sight on people's tables, and vegetable production must be a top priority.

[0003] Transplanting is a common process in vegetable production. Many vegetables can or require transplanting. Obviously, improving the survival rate and efficiency of transplanting is an effective way to ensure vegetable yields. Therefore, continuous research and development of new transplanting technologies to improve the survival rate and efficiency of vegetable transplanting are essential goals.

[0004] Traditionally, seedling transplanting involves using simple, general-purpose farm tools (hoes, spades, and shovels) to dig, shovel, or scoop out the seedlings before planting them in pre-dug seedling pits. This results in significant damage to the seedling's root system, low survival rates, and poor transplanting consistency, resulting in low efficiency. New transplanting technologies with increased efficiency and survival rates are needed. Compared to transplanting machines, seedling transplanters offer flexibility, simplicity, and low cost, making them more suitable for my country's vegetable cultivation practices and widely used.

[0005] my country has already developed some seedling transplanting technology and tools. However, current transplanter research and development focuses on general seedling transplanting movements and device structure descriptions to meet the needs of general seedling transplanting. There is a lack of research on transplanting methods and devices tailored to the specific needs of vegetable transplanting.

[0006] Unlike conventional seedling transplanting, vegetable seedlings have more fragile roots and the soil in the vegetable field is softer and looser, making it difficult to protect the roots and soil during transplanting. Existing transplanters rarely take into account the characteristics of vegetable transplanting and rarely consider the mechanical balance issues during the transplanting process.

[0007] The first one is the problem of balancing the force applied by the single-foot pedal of the seedling transplanter.

[0008] Among the transplanter technologies currently under development, using a transplanting tube is a common transplanting method. However, due to the restriction that the seedlings must be located in the middle of the transplanting tube, a foot pedal has to be welded on the side of the transplanting tube to facilitate applying force to the transplanting tube with the feet and pressing it into the soil.

[0009] When the transplanting tube is inserted into the soil, the reaction force exerted by the soil on the transplanting tube and the human force applied by the welded foot pedals on the side of the transplanting tube are not collinear, causing the transplanting tube to be subjected to a rollover torque during the insertion process. However, existing transplanting devices rarely or do not consider balancing this torque, relying solely on hand-held transplanting devices for balance. Obviously, it is difficult to overcome this rollover tendency using only hand-held transplanting devices. Because the soil around the seedling roots is not completely loosened and separated from the surrounding soil during the insertion of the transplanting tube, the rollover torque exerts a significant pull on the seedling roots, which is particularly detrimental to the fragile roots of vegetable seedlings.

[0010] Of course, among the seedling transplanter technologies currently under development, there is also a seedling transplanter tube that adopts a double-pedal structure, but it is difficult for the human body to apply force to the seedling transplanter tube with both feet at the same time.

[0011] The second problem is the balance of the gap opened on the seedling transplanting tube to make room for the seedlings.

[0012] In order to make the transplanting tube adaptable to larger seedlings, a gap is often opened in the transplanting tube for the seedlings to make way. Although it is convenient for the seedlings to enter the center of the transplanting tube from the side, when the transplanter is stepped into the soil, there is no resistance or little resistance at the gap where the seedlings make way, while the resistance at other parts of the circumference of the transplanting tube is large, so that the combined force of the soil's resistance to the transplanting tube is not in the center of the transplanting tube, and there is also a tendency for the transplanter to tip over, which is not conducive to the fragile root system of vegetable seedlings.

[0013] Moreover, more importantly, after the transplanting tube is inserted into the soil, it does not completely separate the soil at the root of the seedling from the surrounding soil. Subsequently, the transplanting tube must be rotated around its axis to separate the soil inside the tube from the surrounding soil. Due to the presence of the gap, after the transplanting tube is inserted into the soil, during the process of twisting the transplanting tube, a shear force is generated on the soil inside the tube in the part of the soil that is not separated. According to the translation theorem of force, this shear force is equivalent to translating this shear force to the center of the seedling and adding a torque.

[0014] This torque is certainly conducive to the twisting and separation of the soil in the tube, but the seedlings are subjected to a sideways force brought about by the shear force, which is bound to affect the root system of the seedlings.

[0015] The third problem is the wrapping, compaction and fusion of soil around the roots of the seedlings.

[0016] Existing transplanting methods and tools don't consider the issues of wrapping, compacting, and integrating the soil around the seedling roots. During the transplanting process, after the soil inside the transplanting tube is separated from the surrounding soil by rotating, there's no step to compact the soil inside the tube, nor is there a step to integrate the soil after transplanting into the seedling pit with the surrounding new soil.

[0017] In summary, the development of seedling transplanting technology and tools is a key factor influencing seedling survival rate and transplanting efficiency, and thus vegetable yield. However, existing transplanting technology and tools have issues such as balanced force application in the transplanting tube, balanced gaps in the seedlings' clearance, and soil wrapping, compaction, and integration of the seedling roots. Therefore, the development of new methods and tools for vegetable transplanting remains important and urgent. Summary of the Invention

[0027] Another object of the present invention is to provide a method for transplanting seedlings using the above-mentioned vegetable transplanter, the steps of which are as follows:

Support the hand ring with your hands, step on the foot pedal with your left foot, step on the transplanting tube foot pedal with your right foot, and step the transplanting tube into the soil; release your feet, and use your hands to rotate the hand ring back and forth to completely separate the soil inside the transplanting tube from the external soil; lift the hand ring with both hands, move the transplanting tube to the soil storage point, step on the foot pedal ring, and push the soil in the transplanting tube through the push plate to prepare the seedling pit for the target seedling point in advance.

[0049] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0052] See also Figure 1 , shown is a vegetable seedling transplanter based on mechanical balance in the first embodiment of the present invention, the vegetable seedling transplanter includes a seedling transplanting tube assembly 10 and a foot-operated support ring assembly 30 and a push plate assembly 20 sleeved on the seedling transplanting tube assembly 10, the push plate assembly 20 is located below the foot-operated support ring assembly 30, the seedling transplanting tube assembly 10 includes a seedling transplanting tube 101 and two side columns 102 vertically welded on the seedling transplanting tube 101, the side columns 102 are provided with limit screws 105, the foot-operated support ring assembly 30 and the push plate assembly 20 are respectively provided with matching first through holes and second through holes at corresponding positions of the side columns 102, the foot-operated support ring assembly 30 and the push plate assembly 20 are respectively sleeved on the side columns 102 through the first through holes and the second through holes. In order to facilitate the seedling transplanting tube 101 to be stepped into the soil, a seedling transplanting tube foot pedal 103 parallel to the ground is welded on the side of the seedling transplanting tube 101, as shown Figure 2 shown.

[0053] Since the seedlings are located in the center of the seedling transplanting tube 101, it is difficult to set the seedling transplanting tube foot pedal 103 in the center of the seedling transplanting tube 101. If the seedling transplanting tube foot pedal 103 is set on both sides of the seedling transplanting tube 101, both feet must be used to maintain the balance of the seedling transplanting tube 101, but it is difficult for the human body to step on both feet at the same time. If the seedling transplanting tube foot pedal 103 is set on one side of the seedling transplanting tube 101, the reaction force of the soil on the seedling transplanting tube 101 and the stepping force on the seedling transplanting tube 101 by the person constitute a tipping moment. Figure 3 shown.

[0054] It is difficult to balance the transplanting tube 101 by hand alone, which can easily damage the roots of the vegetable seedlings. To solve this problem, the entire vegetable transplanter is used as a mechanical examination system. When the transplanting tube 101 is stepped into the soil, the other foot applies a reverse balancing torque to the transplanter to "hold" the vegetable transplanter, maintain its balance, improve its rigidity, and reduce its deformation.

[0055] That is to say, a footrest support ring assembly 30 is provided, such as Figure 4As shown, the foot support ring assembly 30 includes a foot rod 303 and a foot support ring 301 and a foot pedal 302 respectively welded at both ends of the foot rod 303. The first through hole is set on the foot support ring 301, and the foot pedal 302 is parallel to the ground. The foot pedal 302 is located opposite the seedling transplanting tube foot pedal 103. When transplanting seedlings, the left foot steps on the foot pedal 302. Since the foot support ring assembly 300 is connected to the side column 102 through the first through hole, when the right foot steps on the foot pedal 302 and moves downward, the foot support ring 301 can "hold" the two side columns 102 connected to the seedling transplanting tube 101 to balance the overturning moment, as shown in FIG. Figure 5 shown.

[0056] Since the seedlings are of different sizes, a clearance gap must be opened on the circumference of the transplanting tube 101 to allow large seedlings to enter the vegetable transplanter from the side of the transplanting tube 101. However, after the clearance gap is opened on the transplanting tube 101, two problems are also caused:

[0057] The first problem is that after the transplanting tube 101 is stepped into the soil, the soil inside the tube and the surrounding soil are not completely separated. If the seedlings and soil inside the transplanting tube 101 are regarded as force-bearing objects, then when the transplanting tube 101 is subsequently rotated back and forth to separate the soil inside the transplanting tube 101 from the surrounding soil, the transplanting tube 101 applies a shear force tangent to the circumference of the transplanting tube 101 to the soil inside the tube. According to the principle of force translation, the effect of the shear force on the seedlings and soil in the transplanting tube is equivalent to translating the shear force to the center of the transplanting tube 101 and adding a couple. That is to say, the seedlings and soil located at the center of the transplanting tube 101 are subjected to a thrust equal to the shear force, which causes the seedlings and soil in the tube to have a tendency to overturn and deform, such as Figure 6 shown.

[0058] The second problem is that the resistance of the soil to the transplanting tube 101 is distributed on the circumference of the transplanting tube 101, but there is no soil resistance within the gap of the transplanting tube 101, so that when the transplanting tube 101 is stepped on, the resultant force of the resistance of the soil to the transplanting tube 101 deviates from the center of the transplanting tube 101, and there is also a concern that the transplanting tube 101 may tip over.

[0059] Taking the above two problems into consideration, the transplanting tube 101 is provided with a clearance gap and a balancing gap opposite to the clearance gap. After the transplanting tube 101 is stepped into the soil, the soil in the transplanting tube 101 has two symmetrical places that are not separated from the surrounding soil. In the process of twisting the transplanting tube 101, shear force will be generated at these two places. Figure 7As shown. On the one hand, during the subsequent twisting process of the transplanting tube 101, the shear force on the soil in the transplanting tube is relatively balanced, and the twisting shearing effect of the transplanting tube 101 on the soil in the tube is increased, which is more conducive to the twisting separation of the soil in the tube and the surrounding soil, alleviating problem one. On the other hand, after the balance gap is added, the cutting edge at the bottom of the transplanting tube 101 is also basically symmetrical. During the stepping process of the transplanting tube 101, at least within the height range of the balance gap, the resultant force of the resistance of the soil to the transplanting tube 101 is close to the center of the transplanting tube 101, alleviating problem two.

[0060] In order to enhance the adhesion between the soil and the transplanting tube 101 , resist soil loosening and gravity, and reduce the phenomenon of soil and root shedding, the inner wall of the transplanting tube 101 is further provided with a plurality of punched holes 104 .

[0061] In traditional manual transplanting, it is necessary to pinch the soil around the seedling roots to improve the survival rate of the seedlings. To this end, the processing method of the present invention is as follows: a push plate assembly 20 is provided, such as Figure 8 shown.

[0062] The push plate assembly 20 includes a push rod 201, a foot ring 203 welded to each end of the push rod 201, and a push plate 202. The foot ring 203 has a second through hole that is sleeved onto the side column 102, allowing the push plate assembly 20 to slide on the side column 102. The push plate 202 has a conical disc-shaped structure and is provided with a clearance notch at a position corresponding to the clearance notch. The foot ring 203 is a semi-ring. Both the clearance notch and the semi-ring facilitate the movement of seedlings into and out of the center of the transplanter.

[0063] Finally, step on the pedal ring 203 hard, then the push plate assembly 20 moves downward to the bottom along the side column 102 under the guidance of the side column 102, and the push plate assembly 20 pushes the soil in the transplanting tube 101 together with the seedlings out of the transplanting tube 101. Due to the conical disc structure of the push plate 202, on the one hand, pressure is applied to the soil in the transplanting tube 101 to compact the soil; on the other hand, the push plate 202 is helped to wrap the soil around the roots of the seedlings to a certain extent.

[0064] In addition, the two side columns on the upper part of the existing transplanter are usually connected by a crossbar, which is not conducive to observing the transplanting posture. Figure 9 shown.

[0065] The hand-holding ring 40 is provided with a third through hole at a corresponding position of the side column 102, and the hand-holding ring 40 is assembled on the seedling transplanting tube assembly 10 through the third through hole. The upper part of the side column 102 is connected with the hand-holding ring 40, which facilitates observation of the seedling posture during the transplanting process, facilitates hand-holding, and also enhances the rigidity of the vegetable transplanter.

[0066] The seedling transplanting method based on the above-mentioned vegetable seedling transplanter has the following specific steps:

[0067] The first step is to hold the transplanter and move the transplanting tube 101 to the target seedling point in the vegetable field, support the hand-holding ring 40 with your hands, step on the foot pedal 302 with your left foot, and step on the transplanting tube foot pedal 103 with your right foot to step the transplanting tube 101 into the soil; release your feet, and use your hands to rotate the hand-holding ring 40 back and forth to completely separate the soil inside the tube from the external soil; lift the hand-holding ring 40 with both hands, move the transplanting tube 101 to the soil storage point, step on the foot pedal ring 203, and push the soil in the transplanting tube 101 out by pressing the push plate 202 to prepare a seedling pit for the target seedling point in advance.

[0068] Step 2: Hold the seedling transplanter and move the seedling transplanting tube 101 from the bottom of the side of the seedling to the seedling so that the seedling is located in the center of the seedling transplanting tube 101.

[0069] Step 3: Support the handrail 40 with your hands, step on the pedal 302 with your left foot, step on the transplanting tube pedal 103 with your right foot, and step the transplanting tube 101 into the soil.

[0070] Step 4: After stepping down the seedling transplanting tube 101 , continue to step on the pedal 302 with your left foot and lightly step on the pedal ring 203 with your right foot to compact the soil in the seedling transplanting tube 101 through the push plate 202 .

[0071] Step 5: Release your feet and rotate the hand-holding ring 40 back and forth with your hands to completely separate the soil inside the transplanting tube 101 from the soil outside.

[0072] Step 6: Step on the pedal 302 with your left foot, support the hand ring 40 with your hand, step on the pedal ring 203 with your right foot, and tamp the soil in the seedling transplanting tube 101 by pressing the push plate 202.

[0073] Step 7: Release your feet, lift the hand ring 40 with both hands, aim the transplanter at the seedling pit prepared in advance, step on the pedal ring 203, and push the seedlings together with the soil into the seedling pit.

[0074] Step 8: Move the transplanter from the side of the seedlings, and continue to press the soil around the roots of the seedlings with your feet to promote the fusion of the soil around the roots of the seedlings with the surrounding new soil to complete the transplanting.

[0075] In summary, during the transplanting process, the present invention balances the forces on the seedling roots and the soil, the transplanting process is smooth and precise, and the survival rate of the seedlings is high. The vegetable transplanter is stable in use and has good rigidity; it is flexible, convenient, and reliable to use, and has considerable application prospects.
