Description

Technical Field

[0001] The invention relates to the technical field of seed drills, and in particular to a small self-propelled potato seeding and film covering integrated machine. Background Art

[0002] In the field of agricultural planting, potato sowing has always been a key link in yield and quality. The traditional potato sowing method has gone through stages such as manual sowing and simple mechanical assisted sowing. Early manual sowing was extremely dependent on the experience and physical strength of the planters. It was not only labor-intensive and inefficient, but also difficult to control the sowing accuracy. The seeds were often unevenly sparse, and it was common for one sowing pit to have multiple seeds or missed seeds, which greatly affected the subsequent growth and final yield of potatoes.

[0003] With the advancement of agricultural mechanization, although there are some general-purpose sowing machines, many drawbacks are exposed when applied to greenhouse potato planting scenarios. The greenhouse planting space is closed, land resources are precious, and the planting layout is relatively regular and fine. There are special and strict requirements for sowing accuracy, equipment flexibility and maintenance convenience, which are difficult to meet with ordinary sowing machines. On the one hand, the common sowing machine's material-bearing structure is mostly trough-shaped. During the transportation of potato seeds, the internal vision is severely obstructed, and it is difficult for operators to intuitively monitor the number and status of seeds. There are frequent cases of sowing multiple seeds in one sowing pit, resulting in crowded plants in the seedling stage, competing for nutrients and light, poor growth, and increased disease incidence, which seriously restricts the increase in greenhouse potato yield and quality assurance. At the same time, the trough structure is not conducive to novices to quickly master the key points of operation. When personnel are replaced during the busy farming season, the training cost is high and the start-up is slow, and the sowing process is easily delayed due to human errors.

[0004] Furthermore, traditional seed drills are designed for open fields with relatively flat terrain. When operating in greenhouses with limited space and uneven ground, they lack effective and stable transportation and precise seed placement mechanisms. The conveyor belt has poor operating stability and cannot ensure that potatoes arrive at the sowing location on time and in order. There are no reasonable constraints on the material delivery path, and it is difficult to adapt to the special terrain of the greenhouse to ensure that the spacing between plants and rows is neat and standardized, which brings many inconveniences to subsequent field management such as irrigation, fertilization, and weeding, and increases management costs and difficulties.

[0016] The working principle and beneficial effects of the present invention are: In the present invention, the conveyor belt circulates and runs through the hopper silo, stably conveying potatoes to the receiving tray. This continuous and regular conveying method provides strong support for precise sowing. During greenhouse operations, the equipment needs to operate stably on limited and regular planting rows. The stable operation of the conveyor belt ensures that the potatoes can arrive at the designated position in order and on time, and cooperate with the receiving tray to achieve single-grain load preparation. The lower barrel, with its feed inlet and discharge outlet, further constrains the potato falling path. Even if the greenhouse ground may have certain undulations or unevenness, it can guide the potatoes to accurately fall into the preset sowing site, ensuring that the sowing spacing and row spacing are neat and standardized, creating convenient conditions for potato field management, and is conducive to improving the overall quality and yield of greenhouse potato planting.

[0017] The working environment inside the greenhouse is relatively special, and the light and space layout are different from those of the outdoor field. The plate design of the receiving tray makes it convenient for operators to observe the transportation and loading status of potatoes at all times, without the need to bend over, turn sideways, and other laborious actions to confirm the number of seeds. During the sowing process of the equipment, operators can easily and promptly find abnormalities (such as potato jams, multi-seed accumulation, etc.) and deal with them quickly, which greatly reduces the labor intensity and reduces fatigue misjudgments caused by long-term work. For example, the traditional trough structure may be difficult to quickly detect the problem of multiple seeds due to the obstruction of internal vision. It will not be discovered until after sowing, and the cost and difficulty of correction are high at that time; while the plate-type receiving tray makes the problem clear at a glance, ensuring a smooth and efficient sowing process, improving the success rate of a single sowing operation, saving greenhouse planting time costs, and at the same time making it easier for operators to add seeds to the unloaded potato receiving tray.

[0018] Moreover, clear visual operation helps new or inexperienced agricultural workers get started quickly. Greenhouse planting often faces the problem of shortage of manpower during the busy farming season and uneven worker proficiency. The convenient observation feature of the receiving tray allows novices to accurately control the sowing process after simple training, reduce human sowing errors, improve the overall efficiency of greenhouse potato sowing operations, and ensure that the planting progress is carried out on time.

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0022] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0023] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] Reference Figure 1~Figure 4 , which is the first embodiment of the present invention, proposes a small self-propelled potato sowing and film covering machine, including a hopper 1, the hopper 1 has a silo 101, the silo 101 has an inlet 102 and an outlet 103, the silo 101 is used to accommodate potatoes, a conveyor belt 2 is circulated on the hopper 1 and passes through the silo 101, the rotation direction of the conveyor belt 2 is configured to enter from the inlet 102 and move out from the outlet 103, there are a plurality of receiving trays 3, which are arranged in sequence on the conveyor belt 2, the receiving trays 3 are plate-shaped, a lower barrel 4 is arranged on the hopper 1 and is located on one side of the hopper 1, the conveyor belt 2 passes through the lower barrel 4, and the lower barrel 4 has a feed inlet 402 and a discharge outlet 403.

[0026] In the present embodiment, the receiving tray 3 is designed as a plate type. This unique structure is in sharp contrast to the common trough structure, and its greatest advantage is that it is easy for the operator to observe clearly. The operator can intuitively confirm that there is only one potato on the receiving tray 3, thereby effectively avoiding the situation where multiple potato seeds appear in a sowing pit. Accurate single seed sowing ensures that each potato seedling has sufficient growth space, nutrients and light, reduces competition between seedlings, and enables potato plants to thrive in the early stages of growth, laying a solid foundation for high yields in the later stages. For example, if multiple seeds are planted in a pit, the seedlings will compete with each other for water, fertilizer and sunlight after they emerge from the soil, resulting in thin and weak plants and easy to get sick, which ultimately affects the overall yield and quality of potatoes. The design of the receiving tray 3 can kill this hidden danger in the bud.

[0027] At the same time, single-seed precision sowing is in line with the concept of refined management in greenhouses. In a greenhouse environment, growers often invest more costs in fine control links such as fertilizers, irrigation and temperature control. Precise sowing can better match a series of subsequent refined operations, ensuring that various inputs can be efficiently converted into potato output and improving economic benefits.

[0028] The conveyor belt 2 circulates through the hopper 1 silo 101, and stably conveys potatoes to the receiving tray 3. This continuous and regular conveying method provides strong support for precise sowing. During greenhouse operations, the equipment needs to operate stably on limited and regular planting rows. The stable operation of the conveyor belt 2 ensures that the potatoes can arrive at the designated position in order and on time, and cooperate with the receiving tray 3 to achieve single-grain load preparation. The lower barrel 4, with its feed port 402 and discharge port 403, further constrains the potato falling path. Even if the greenhouse ground may have certain undulations or unevenness, it can guide the potatoes to accurately fall into the preset sowing site, ensuring that the sowing spacing and row spacing are neat and standardized, creating convenient conditions for potato field management, and helping to improve the overall quality and yield of greenhouse potato planting.

[0029] The working environment inside the greenhouse is relatively special, and the light and space layout are different from those of the outdoor field. The plate design of the receiving tray 3 makes it convenient for the operator to observe the potato transportation and carrying status at all times, without the need to bend over, turn sideways, and other laborious actions to confirm the number of seeds. During the sowing process of the equipment, the operator can easily and promptly find abnormalities (such as potato jams, multi-seed accumulation, etc.) and deal with them quickly, which greatly reduces the labor intensity and reduces fatigue misjudgments caused by long-term work. For example, the traditional trough structure may be difficult to quickly detect the problem of multiple seeds due to the obstruction of internal vision. It will not be discovered until after sowing, and the cost and difficulty of correction are high at that time; while the plate-type receiving tray 3 makes the problem clear at a glance, ensures a smooth and efficient sowing process, improves the success rate of a single sowing operation, saves the time cost of greenhouse planting, and is convenient for operators to add seeds to the unloaded potato receiving tray 3.

[0030] Moreover, clear visual operation helps new or inexperienced agricultural workers to quickly get started. Greenhouse planting often faces the problem of shortage of manpower during the busy farming season and uneven proficiency of workers. The convenient observation feature of the receiving tray 3 enables novices to accurately control the sowing process after simple training, reduce human sowing errors, improve the overall efficiency of greenhouse potato sowing operations, and ensure that the planting progress is carried out on time.

[0031] The small self-propelled integrated machine has a compact overall structure, which is cleverly composed of a hopper 1, a conveyor belt 2, a receiving tray 3 and a lower barrel 4, which is very suitable for the limited and regular space characteristics of a greenhouse. Compared with large outdoor sowing equipment, it can flexibly shuttle between narrow greenhouse aisles and planting rows, turn and turn around conveniently, and does not require the assistance of a large area of ​​flat ground.

[0032] The structures of the hopper 1, conveyor belt 2, receiving tray 3 and discharge barrel 4 are relatively simple, which makes maintenance easy in a greenhouse environment where the temperature and humidity are relatively stable but still have certain special features. When it is necessary to clean the residual dirt and debris in the hopper 1, it can be quickly disassembled, cleaned and reassembled due to its clear structure; it is easy to check the wear of the transmission parts (pulleys, motors, etc.) of the conveyor belt 2 and adjust the belt tightness; the plate structure of the receiving tray 3 is intuitive, and deformation and damage are clear at a glance; it is also easy to check the patency of the discharge barrel 4 and clear blockages. Daily maintenance is convenient and efficient, shortening equipment downtime, ensuring the continuous availability of equipment during the greenhouse potato planting season, and reducing the impact of equipment failures on planting production.

[0033] Furthermore, the material discharge barrel 4 has a material discharge chamber 401, the cross section of which is the same shape as that of the receiving tray 3 and has a movable gap, and also includes a leak-proof barrel 5, which is arranged on the hopper 1 and is located on the side of the inlet 102. The leak-proof barrel 5 has a connecting chamber 501, which leads to the inlet 102. The connecting chamber 501 has the same shape as that of the receiving tray 3, and the conveyor belt 2 passes through the connecting chamber 501. The receiving tray 3 is configured so that during the operation of the conveyor belt 2, there is at least one receiving tray 3 in the leak-proof barrel 5.

[0034] In this embodiment, the lower barrel 4 has a lower cavity 401, whose cross section is the same shape as the receiving tray 3 and has a certain gap. This design provides an extremely accurate guide for the transfer of potatoes from the receiving tray 3 to the sowing site. When the receiving tray 3 moves to the top of the lower barrel 4 along with the conveyor belt 2, the potatoes can naturally and smoothly fall along the lower cavity 401 under the action of gravity because the lower cavity 401 matches the shape of the receiving tray 3, avoiding the potato getting stuck, rolling and deflecting due to the inconsistency of the channel shape. At the same time, the receiving tray 3 also avoids the disorderly falling of potatoes. Potatoes falling from an upper receiving tray 3 can be received by the lower receiving tray 3 until they fall out of the discharge port 403.

[0035] At the same time, this shape matching design also helps to reduce damage to potatoes during the feeding process. Compared with the frequent collision and friction between potatoes and the feeding cavity wall caused by shape mismatch, the feeding cavity 401 of the same shape can make potatoes fall smoothly, reduce the risk of damage to the potato surface, ensure the integrity of potato seeds, and facilitate the normal germination and growth of potatoes.

[0036] The leak-proof cylinder 5 is arranged on the hopper 1 and is located on one side of the inlet 102. Its connecting cavity 501 leads to the inlet 102 and has the same shape as the receiving tray 3. At the same time, the conveyor belt 2 runs through the connecting cavity 501, and ensures that there is at least one receiving tray 3 in the leak-proof cylinder 5 during the operation of the conveyor belt 2. This series of designs effectively prevents the leakage of potatoes during the transportation process. In the potato sowing operation, especially in the greenhouse environment, the space is relatively closed and requires delicate operation. Any leakage of potatoes may cause inaccurate sowing sites or cause confusion in the greenhouse, affecting subsequent planting management. The leak-proof cylinder 5 matches the shape of the connecting cavity 501 with the receiving tray 3 and reasonably configures the receiving tray 3, so that potatoes can be orderly carried on the receiving tray 3 during the process of entering the conveyor belt 2 from the hopper 1. Even if there is a slight shake or other interference factors during the operation of the equipment, it can ensure that potatoes will not leak from the connecting cavity 501, maintain the stability and integrity of potato transportation, and ensure the smooth progress of the sowing operation.

[0037] The design of the material discharge chamber 401 of the material discharge barrel 4, the connecting chamber 501 of the leak-proof barrel 5 and the material receiving plate 3 having the same shape not only realizes accurate material discharge and prevents material leakage in terms of function, but also brings advantages in terms of space utilization. This shape matching makes the connection and layout of each component more regular and reasonable, and reduces the space waste that may be caused by shape differences.

[0038] Despite the addition of components such as the discharge barrel 4 and the leak-proof barrel 5, the operation process of the small self-propelled potato sowing and film covering integrated machine remains simple and easy to understand. Simply load the potatoes into the hopper 101 of the hopper 1 through the connecting cavity 501 of the leak-proof barrel 5 (that is, through the inlet 102), and then start the equipment, the conveyor belt 2 will automatically start to operate, transport the potatoes to the receiving tray 3 in turn, and complete the discharge and sowing operation through the discharge barrel 4. The entire operation process has clear steps and does not require high professional skills, which still greatly reduces the training cost of farmers, increases farmers' enthusiasm for using the equipment, and is conducive to the promotion and application of the equipment. Due to the simple operation, during the sowing process, the operating parameters of the equipment (such as the speed of the conveyor belt 2, etc.) can be quickly adjusted according to the actual situation (such as field soil conditions, potato varieties, etc.), without spending a lot of time on complex equipment adjustments, improving the sowing efficiency and ensuring the continuity of sowing.

[0039] The structural design of the unloading barrel 4, the leak-proof barrel 5, the hopper 1, the conveyor belt 2, the receiving tray 3 and other components makes the equipment more convenient in terms of maintenance and inspection. When the unloading barrel 4 needs to be cleaned, repaired or replaced, the maintenance personnel can perform the relevant operations relatively easily because its structure is relatively simple and matches the shape of the receiving tray 3. For example, it is more intuitive and convenient to check whether the unloading chamber 401 is unobstructed and whether there are any blockages. Similarly, for the leak-proof barrel 5, the patency of the connecting chamber 501 and whether its connection with other components is firm can be checked. For the original components such as the hopper 1, the conveyor belt 2, and the receiving tray 3, the maintenance and inspection method is similar to the previous one, which is still simple and fast. The whole process is simple and fast, which greatly shortens the maintenance time, improves the availability of the equipment, and ensures the continuity of production. Moreover, in daily maintenance, it is only necessary to regularly perform simple inspections and maintenance operations on these components, such as cleaning the hopper 1 and lubricating the transmission components of the conveyor belt 2, to keep the equipment in good operating condition, further simplifying the maintenance process of the equipment and improving the availability of the equipment.

[0040] Furthermore, it also includes a frame 6, a hopper 1 is arranged on the frame 6, a fertilizer storage bin 7 is arranged on the frame 6, and is located on the side of the hopper 1 away from the lower barrel 4. The fertilizer storage bin 7 has a fertilizer outlet 701, and a guide frame 8 is arranged on one side of the fertilizer storage bin 7. The guide frame 8 has a slide 801, and the fertilizer outlet 701 leads to the slide 801. The slide 801 has a drop port 802, and the drop port 802 is located on one side of the frame 6.

[0041] In this embodiment, the fertilizer storage bin 7 is arranged on the frame 6 and is located on the side of the hopper 1 away from the lower barrel 4. It has a fertilizer outlet 701, which can effectively store the fertilizer required for potato planting. In the process of greenhouse potato planting, reasonable fertilization is a key link to ensure potato yield and quality. The existence of the fertilizer storage bin 7 enables the fertilizer to move with the equipment, without the need to carry the fertilizer to the planting area additionally, saving manpower and time costs. The guide frame 8 is arranged on one side of the fertilizer storage bin 7, which has a chute 801, the fertilizer outlet 701 leads to the chute 801, and the chute 801 has a drop port 802 located on one side of the frame 6. This design realizes the precise guidance and delivery of fertilizer. When fertilization is needed, the fertilizer flows out from the fertilizer outlet 701 of the fertilizer storage bin 7, enters the chute 801 of the guide frame 8, and then accurately falls on the preset fertilization position through the drop port 802, next to the potato planting row or pit. Accurate fertilization location helps potato roots absorb fertilizer nutrients in time, improves fertilizer utilization, and avoids fertilizer waste and potato growth differences caused by uneven fertilization.

[0042] The hopper 1 is used to hold potato seeds, and the fertilizer storage bin 7 is responsible for storing fertilizers. The two work together with other components on the frame 6 (such as the conveyor belt 2, the lower barrel 4, etc.) to achieve seamless connection between potato sowing and fertilization operations. In greenhouse planting operations, sowing and fertilization are usually two closely linked links. The all-in-one machine integrates these two functions together, so that simultaneous fertilization can be performed as needed while sowing, which optimizes the planting process, reduces the time interval between operation links, and improves the overall planting efficiency. For example, after the potatoes are sown through the lower barrel 4, fertilization operations can be performed immediately through the fertilizer storage bin 7 and the guide frame 8, providing immediate nutrient support for the potato seeds, which is conducive to rapid germination of seeds and healthy growth of seedlings, saving time and labor costs for subsequent separate fertilization.

[0043] The frame 6 serves as the bearing platform of the whole machine, and the hopper 1, fertilizer storage bin 7 and other components are reasonably arranged on it. The hopper 1 is arranged on the frame 6 for storing and transporting potato seeds, and the fertilizer storage bin 7 is located on the side of the hopper 1 away from the lower barrel 4. This layout makes full use of the space of the frame 6, so that each component is in its proper place within the limited frame area, without interfering with each other, and can realize its own function, thereby improving the utilization rate of land and space in the greenhouse and facilitating the movement and operation of the equipment in the greenhouse.

[0044] Moreover, the compact layout helps to enhance the overall stability of the equipment. The various components are tightly connected and reasonably distributed on the frame 6. During the operation of the equipment, it can better resist external force interference that may occur in the greenhouse environment, such as ground bumps, air flow fluctuations, etc. When the all-in-one machine is walking in the greenhouse to perform sowing and fertilizing operations, even if there are some slight shakes, the relative positions of the various components can remain stable, and there will be no loosening, falling off, or affecting the operation effect, which ensures the normal operation of the equipment and improves the reliability of the equipment.

[0045] Furthermore, it also includes a fixed frame 9, which is arranged on the frame 6 and located in the middle of the frame 6. There are two adjusting rods 10, one end of the two adjusting rods 10 is hinged to the fixed frame 9, and a ditching member 11 is hinged to the other end of the two adjusting rods 10. The fixed frame 9, the two adjusting rods 10 and the ditching member 11 form a parallelogram structure. The ditching member 11 is located in front of the discharge barrel 4. The connecting block 12 is arranged on an adjusting rod 10, and the first swinging driving member 1201 is arranged on the frame 6. The first swinging driving member 1201 is hinged to the connecting block 12, and the first swinging driving member 1201 is used to drive the adjusting rod 10 to rotate. After the adjusting rod 10 rotates, the ditching member 11 is inserted into or leaves the ground.

[0046] In this embodiment, the parallelogram structure formed by the fixed frame 9, the two adjustment rods 10 and the ditching member 11 brings significant advantages to the ditching operation. During the operation of the equipment, this structure can ensure that the movement trajectory of the ditching member 11 is more stable and precise. When the all-in-one machine is walking in the greenhouse to perform potato sowing operations, even if the ground is uneven or the equipment itself shakes slightly, the parallelogram structure can automatically adjust and maintain the relative position relationship between the ditching member 11 and the ground by virtue of its own geometric characteristics, so that the ditching member 11 always follows a predetermined trajectory when inserted into or leaving the ground, effectively avoiding the deviation of the ditching position caused by shaking or unevenness, thereby ensuring that the position of the pits opened is accurate and the shape is regular, laying a solid foundation for the subsequent accurate sowing of potato seeds. The stability of the parallelogram structure is also reflected in the consistency of the ditching depth. Regardless of the working state of the device, by reasonably setting the rotation parameters of the adjustment rod 10 and the driving force of the first swing driving member 1201, the depth of the trenching member 11 inserted into the ground each time can be kept relatively stable, ensuring that the depth of each pit meets the requirements of potato planting. This is crucial for the growth and development of potatoes, because different varieties of potatoes may have specific requirements for the depth of the pits, and a stable trenching depth can provide a suitable implantation environment for potato seeds, which is conducive to the rooting, germination and subsequent growth of the seeds.

[0047] One end of the adjusting rod 10 is hinged to the fixing frame 9, and the other end is hinged to the ditching member 11, and is connected to the first swinging driving member 1201 through the connecting block 12. This connection mode enables the adjusting rod 10 to rotate flexibly under the drive of the first swinging driving member 1201. This feature gives the ditching member 11 strong adaptability and can meet the ditching needs under different soil conditions and planting requirements. For example, in the soft soil of the greenhouse soil, the driving force of the first swinging driving member 1201 can be appropriately adjusted to make the adjusting rod 10 rotate at a moderate angle, so that the ditching member 11 can be easily inserted into the ground and open a pit of a suitable depth, while avoiding excessive force causing the pit to be too large or too deep; in the soil environment with hard soil, the driving force of the first swinging driving member 1201 can be increased to make the adjusting rod 10 rotate at a larger angle to ensure that the ditching member 11 can smoothly penetrate the hard soil layer and open a pit that meets the requirements.

[0048] The furrowing member 11 is located in front of the lower barrel 4. This layout design allows the furrowing operation to be closely connected with the sowing operation, realizing the efficient integration of the potato planting process. When the furrowing member 11 is inserted into the ground to make a hole under the drive of the first swing drive member 1201, the lower barrel 4 will then accurately sow the potatoes carried on the receiving plate 3 into the newly opened hole. The entire process does not require manual intervention, and realizes the automated furrowing and sowing connection, greatly improving the planting efficiency, while also reducing the errors that may be caused by manual operation, ensuring that each potato seed can be accurately sown in a suitable hole, creating good conditions for the growth of potatoes.

[0049] Furthermore, it also includes a ridging frame 13, which is swingably set on the frame 6. The ridging frame 13 and the furrowing member 11 are respectively located on the front and rear sides of the lower barrel 4. After the ridging frame 13 swings, it is close to or away from the ground. The rotary tillage shaft 14 is rotatably set on the ridging frame 13. The rotary tillage shaft 14 is used to crush soil. The ridging board 15 has a plurality of pieces, which are obliquely set on the ridging frame 13 and are located behind the rotary tillage shaft 14. The ridging board 15 is used to shape the soil crushed by the rotary tillage shaft 14 into ridges.

[0050] In this embodiment, the addition of components such as the ridging frame 13, the rotary tillage shaft 14, and the ridging board 15 further improves the integrated process of potato planting. The ridging frame 13 is swingably set on the frame 6 and is located on the front and rear sides of the lower barrel 4 respectively with the furrowing member 11, so that the equipment can effectively organize the land before sowing potatoes. The rotary tillage shaft 14 is rotatably set on the ridging frame 13 and can start crushing the soil when the ridging frame 13 is close to the ground. Its function is to break the soil compaction, improve the soil structure, and create good soil conditions for potato growth. For example, when planting potatoes in a greenhouse, the soil after a season of crop planting is often easy to compact. The crushing function of the rotary tillage shaft 14 can make the soil loose, which is conducive to the extension of the potato root system and nutrient absorption.

[0051] Then, the ridging board 15 located behind the rotary tillage shaft 14 shapes the crushed soil into ridges. The inclined setting and multi-piece design of the ridging board 15 can accurately shape the ridge shape and specifications that meet the planting requirements. After the ridges are shaped, the furrowing piece 11 performs the furrowing operation, and then the lower barrel 4 sows the potato seeds into the pit. The whole process is closely linked, achieving a seamless connection from land preparation to sowing, greatly reducing manual intervention and the time interval between each link, and significantly improving the overall efficiency of potato planting.

[0052] The swiveling setting of the ridging frame 13 enables it to flexibly adjust the distance from the ground according to different soil conditions and planting requirements, thereby controlling the degree of soil crushing by the rotary tillage shaft 14. In areas with soft soil, the ridging frame 13 can be appropriately swung closer to the ground to allow the rotary tillage shaft 14 to perform moderate soil crushing; while in areas with harder soil, the ridging frame 13 can be closer to the ground to allow the rotary tillage shaft 14 to penetrate the soil and fully crush it. This adjustability ensures that effective land preparation can be achieved for different soil conditions and meets the soil looseness requirements for potato planting.

[0053] The number of settings and inclination angles of the ridge forming boards 15 can be adjusted according to different potato varieties, planting patterns, greenhouse environment and other factors. For example, for potato varieties with large water requirements, the inclination angle and spacing of the ridge forming boards 15 can be adjusted to shape ridges with better water retention performance; for densely planted potato planting patterns, the spacing of the ridge forming boards 15 can be appropriately reduced to increase the number of ridges and improve land utilization. Through these precise adjustments, various potato planting needs can be better met to ensure the growth quality and yield of potatoes.

[0054] Furthermore, an installation space 1301 is formed between the ridging board 15 and the ridging frame 13, and also includes a film covering shaft 17, which is rotatably arranged at the rear side of the ridging frame 13, and is used to install a ground film roll. A soil raising piece 16 is rotatably arranged on the ridging frame 13 and is located in the installation space 1301. During the process of the rotary tillage shaft 14 crushing the soil, the soil is raised and part of the soil is thrown into the installation space 1301. The soil raising piece 16 is located on one side of the film covering shaft 17, and is used to throw the soil onto the film released by the film covering shaft 17. A cloth belt piece 18 is rotatably arranged on the ridging frame 13, and is used to install a dropper belt roll.

[0055] In this embodiment, the installation space 1301 formed between the ridging board 15 and the ridging frame 13, as well as the newly added film covering shaft 17, soil lifting piece 16 and cloth belt piece 18, further improve the integrated operation process of potato planting. Before sowing potatoes, the rotary tillage shaft 14 crushes the soil and at the same time lifts part of the soil and throws it into the installation space 1301. Subsequently, the ridging board 15 shapes the crushed soil into ridges, followed by furrowing by the furrowing piece 11, and the lower barrel 4 sows. After sowing, the film covering shaft 17 can be used for film covering immediately. It is rotatably arranged at the rear side of the ridging frame 13 for installing the ground film roll. By releasing the film to cover the ridges, a suitable temperature and humidity environment is created for potato growth, reducing the growth of weeds, etc. For example, in greenhouse potato planting, film covering can effectively maintain soil moisture, increase ground temperature, and promote early germination and growth of potatoes.

[0056] At the same time, the cloth belt member 18 is rotatably arranged on the ridge frame 13 for installing the drip tape roll, which can realize the synchronous laying of the drip irrigation tape to provide precise irrigation for potato growth. This coordinated operation of sowing, film covering, and laying of drip irrigation tape greatly reduces manual intervention and the time interval between each link, and realizes the seamless connection from land preparation, sowing to subsequent field management measures (film covering and irrigation), which significantly improves the overall efficiency and refined management level of potato planting.

[0057] The soil-raising member 16 is located on one side of the film-covering shaft 17 and in the installation space 1301. It can accurately throw the soil that falls into the installation space 1301 after being broken and raised by the rotary tillage shaft 14 onto the film released by the film-covering shaft 17. This process realizes the soil-covering operation of the film. On the one hand, the soil-covering can further fix the film, prevent the film from being blown up or shifted by the wind, and ensure the stability of the film-covering effect; on the other hand, the appropriate amount of soil-covering can regulate the air permeability and temperature of the soil to a certain extent, creating better conditions for the germination of potato seeds and the growth of seedlings. For example, when the temperature is low in spring, the appropriate thickness of soil-covering can play a certain role in heat preservation, which is conducive to the early emergence of potato seedlings.

[0058] The film covering shaft 17 accurately releases the film and covers the ridges, ensuring that the surface of the ridges can be evenly covered with the film, providing a relatively closed and suitable microenvironment for potato growth. Potato planting in different regions and seasons may have different requirements for film covering. By adjusting the rotation speed of the film covering shaft 17, the laying tension of the film and other parameters, the film covering quality can be accurately controlled to meet the needs under various planting conditions and ensure the growth quality and yield of potatoes.

[0059] During the process of the rotary tillage shaft 14 breaking the soil, some of the soil will be lifted up, and the soil lifting member 16 cleverly utilizes this part of the soil resources that are lifted up. Without the soil lifting member 16, the soil that is lifted up may be scattered everywhere, causing a waste of soil resources and may affect the working environment around the equipment. The soil lifting member 16 collects the soil and throws it onto the film released by the film covering shaft 17, realizing the effective reuse of this part of the soil, saving the manpower and time required for additional covering, and making full use of the soil resources that may have been wasted, thereby improving the economic efficiency of the planting operation.

[0060] Moreover, the rotating setting of the soil throwing member 16 enables it to flexibly adjust the angle and strength of soil throwing according to different soil textures and the operating conditions of the rotary tillage shaft 14, ensuring that the soil can accurately fall on the film and adapt to different planting environments and soil conditions.

[0061] The tape member 18 is used to install a drip irrigation tape roll, which can meet various potato planting requirements and improve the adaptability to different planting environments.

[0062] Furthermore, the cloth belt member 18 has a first mounting portion 1801 and a second mounting portion 1802, both of which are used to install a drip irrigation tape roll. The small self-propelled potato sowing and film covering machine also includes a first guide member 19, which is arranged below the ridge forming frame 13, located in the middle of the ridge forming frame 13, and located in the center of the frame 6. The first guide member 19 has a guide groove 1901, which extends from the cloth belt member 18 to below the film covering shaft 17, and is used to guide the drip irrigation tape roll of the first mounting portion 1801 to below the film covering shaft 17. The second guide member 20 is arranged below the ridge forming frame 13 and is located on the side close to the drop port 802. There are several second guide members 20, which extend from the cloth belt member 18 to below the film covering shaft 17, and are used to bypass the drip irrigation tape roll on the second mounting portion 1802 in sequence, guide the drip irrigation tape roll to below the film covering shaft 17, and slide into the ridge ditch along the side wall of the ridge.

[0063] In this embodiment, the first guide member 19 is arranged below the ridge-forming frame 13 and is located in the middle and centered with the frame 6. Its guide groove 1901 extends from the cloth belt member 18 to below the film-covering shaft 17, providing an accurate and stable guide path for the drip tape roll of the first mounting portion 1801. In the potato planting process, the laying accuracy of the drip tape is crucial to the subsequent irrigation effect. A slight deviation may cause some potato plants to be unable to be effectively irrigated or unevenly irrigated. Through the guide groove 1901, the drip tape can be smoothly and accurately guided to the bottom of the film-covering shaft 17, ensuring that it can be laid synchronously and accurately at a suitable position above the ridge with the film-covering operation, and fit closely with the film to avoid problems such as distortion and offset of the drip tape, thereby ensuring the linearity and flatness of the drip tape laying and creating good conditions for uniform irrigation.

[0064] The second guide members 20 are located below the ridge frame 13 and near the side of the drop port 802. There are several of them. They extend from the cloth belt member 18 to the bottom of the film covering shaft 17 and fall into the ridge ditch, cleverly guiding the drip irrigation tape roll on the second mounting part 1802 to bypass and reach the designated position in turn. This multi-guide design adapts to different laying requirements, especially in complex field ridge terrain or diverse planting layouts. It can flexibly adjust the direction of the drip irrigation tape so that it can be stably laid on one side of the film covering shaft 17, forming a complementary irrigation layout with the drip irrigation tape laid on the ridge, covering the field ridge in all directions, meeting the precise water requirements of potatoes at different growth stages, and improving irrigation efficiency and quality.

[0065] The double mounting parts 1801 and 1802 of the cloth belt part 18 are combined with the first guide part 19 and the second guide part 20, and are closely integrated into the overall planting process of the integrated machine. When the equipment is running, after completing the preliminary operations such as land rotary tillage, ridge formation, furrowing, and sowing, as the film covering shaft 17 prepares for film covering, the laying of the drip irrigation tape starts synchronously. The drip irrigation tape rolls of the first mounting part 1801 and the second mounting part 1802 are respectively positioned above and below the film covering shaft 17 under the guidance of their respective guide parts, so that sowing, film covering and drip irrigation tape laying can be completed in one go, which greatly reduces the time consumption of connection between processes, optimizes the sequence of operation processes, increases the operating area of ​​the equipment per unit time, improves the overall planting efficiency, and meets the needs of efficient potato planting rhythm in greenhouses.

[0066] The tape member 18 has a first mounting portion 1801 and a second mounting portion 1802, and can carry drip tape rolls of different specifications (such as pipe diameter, dripper spacing, etc.) or types at the same time to cope with the complex and changeable irrigation needs in potato planting. For example, in a sandy soil greenhouse area with poor soil water retention and large evaporation, a drip tape with dense dripper spacing and larger flow rate can be installed on the first mounting portion 1801, and a conventional drip irrigation tape can be installed on the second mounting portion 1802. The first guide member 19 and the second guide member 20 are used to lay them according to different paths to achieve zoned and layered irrigation, flexibly allocate water supply, ensure that potatoes can obtain suitable water nourishment under different soil conditions, and improve plant survival rate and yield.

[0067] The setting of the guide can be flexibly adjusted according to the actual planting layout. In the wide and narrow row planting mode, by fine-tuning the angle and position of the first guide 19 and the second guide 20, the laying trajectory of the drip tape can be accurately changed, so that the drip tape can be accurately placed on the corresponding row position, and the width of the field ridge can be changed to optimize the irrigation coverage, avoid water waste, ensure that each row of potatoes can be effectively irrigated, and adapt to the diversified greenhouse planting design requirements.

[0068] Furthermore, it also includes a guide plate 21, which is arranged on one side of the coring board 15 and is used to guide the turned-up soil to the side of the coring board 15.

[0069] In this embodiment, the guide plate 21 is arranged on one side of the ridging board 15. After the rotary tillage shaft 14 crushes and turns up the soil, the guide plate 21 can play a key role and accurately guide the turned up soil to the side of the ridging board 15. This precise guiding function allows the soil to flow to the ridging board 15 in a more orderly manner, providing convenience for the ridging operation. For example, in the greenhouse potato planting process, the soil crushed by the rotary tillage shaft 14 may appear in a more scattered state. Without the guidance of the guide plate 21, part of the soil may not be able to reach the location of the ridging board 15 in a timely and accurate manner, thereby affecting the speed and quality of ridging. The guide plate 21 can ensure that the soil flows to the ridging board 15 in a concentrated and smooth manner, speeding up the ridging process and improving the efficiency of the ridging operation.

[0070] At the same time, accurate soil guidance also helps to improve the quality of ridge formation. The ridge forming plate 15 relies on the soil guided from the guide plate 21 to shape the field ridges. Since the flow direction of the soil is more regular, the ridge forming plate 15 can more evenly use the soil to shape the field ridges with regular shapes, heights and widths that meet the requirements. The ridges formed in this way are conducive to field management operations such as irrigation and fertilization after potato planting, provide a good soil foundation for the growth of potatoes, and ensure the yield and quality of potatoes.

[0071] Furthermore, the trenching member 11 has a pointed insertion portion 1101 and a connecting portion 1102, the connecting portion 1102 is used to connect with the adjusting rod 10, the pointed insertion portion 1101 has a mud insertion cavity 1103, the mud insertion cavity 1103 is used to guide the pointed insertion portion 1101 when inserted into the soil, and the pointed insertion portion 1101 is used to connect with two adjusting rods 10.

[0072] In this embodiment, the design of the pointed insertion portion 1101 and the connecting portion 1102 of the ditching member 11 enables it to have better performance in the ditching operation. The connecting portion 1102 is used to firmly connect with the adjusting rod 10, ensuring that the ditching member 11 can accurately perform the ditching action as the adjusting rod 10 rotates during the operation of the equipment, ensuring the controllability of the ditching position and depth. For example, in greenhouse potato planting, the planting layout of different areas may have specific requirements for the spacing and depth of the planting furrows. Through the stable connection between the adjusting rod 10 and the connecting portion 1102, the landing point and insertion depth of the ditching member 11 can be accurately controlled to meet diverse planting needs.

[0073] The shape of the pointed insertion part 1101 has obvious advantages. Its conical structure can be inserted into the soil more easily, especially in some greenhouse soil environments with relatively compact soil. Compared with other shapes of trenching parts, the pointed insertion part 1101 can reduce the resistance when inserted into the soil with its gradually tapering shape, making the trenching process smoother and improving the trenching efficiency.

[0074] Furthermore, it also includes a second swing driving member 22, which is arranged on the frame 6 and is used to drive the ridging frame 13 to swing.

[0075] In this embodiment, the second swing driving member 22 is arranged on the frame 6, and is specifically used to drive the ridge-forming frame 13 to swing, so that the swinging action of the ridge-forming frame 13 can be controlled more accurately. In the potato planting process, the accuracy of the ridge-forming operation is crucial to the subsequent growth and development of potatoes. For example, different varieties of potatoes may have different requirements for parameters such as the height, width, and ridge spacing of the ridges. By accurately adjusting the swing amplitude, frequency, etc. of the ridge-forming frame 13 through the second swing driving member 22, the ridges that meet the planting requirements of specific potato varieties can be accurately shaped.

[0076] Moreover, precise drive control can ensure that the ridging frame 13 moves more smoothly and accurately when approaching or moving away from the ground. When performing land preparation and ridging operations, the ridging frame 13 needs to maintain a suitable distance from the ground to achieve effective crushing of the soil by the rotary tillage shaft 14 and accurate shaping of the soil by the ridging plate 15. The second swing drive member 22 can prevent the ridging frame 13 from swinging excessively or not in place, ensuring the stability of the ridge shaping process, thereby improving the quality of the ridging operation.

[0077] The second swing drive member 22 cooperates with the ridging frame 13, the rotary tillage shaft 14, the ridging board 15 and other components to further optimize the ridging process to adapt to different planting conditions. For example, in the soft soil of the greenhouse, the swing amplitude of the ridging frame 13 can be appropriately reduced by the second swing drive member 22, so that the rotary tillage shaft 14 can perform appropriate crushing operations to avoid excessive crushing and damage to the soil structure. At the same time, the ridging board 15 can also accurately shape suitable ridges according to the posture of the adjusted ridging frame 13; in a soil environment with harder soil, the swing amplitude of the ridging frame 13 can be increased to allow the rotary tillage shaft 14 to penetrate deeper into the soil for more sufficient crushing, ensuring that the ridging board 15 can use the crushed soil to shape ridges that meet the requirements. This collaborative operation mode can flexibly adjust the ridging operation parameters according to different soil textures, improve the adaptability of the equipment to different planting environments, and ensure the quality and yield of potato planting.

[0078] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
