Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of potato planting equipment, and in particular, to a multi-ridge double-film ridging and covering machine. Background Art

[0002] Sweet potato, also known as sweet potato, is a perennial twining vine plant of the Dioscorea family and Dioscorea genus. It is a high-yield and highly adaptable food crop that is closely related to industrial and agricultural production and people's lives. In addition to being a staple food, the tuber is also an important raw material for food processing, starch and alcohol manufacturing industries, and the roots, stems and leaves are excellent feed.

[0003] Therefore, the planting of sweet potatoes is also a matter of close concern. In order to improve the planting effect of sweet potatoes, film mulching planting technology has emerged. This technology uses film mulching to increase ground temperature and maintain soil moisture, thereby promoting rapid growth and improving yield and quality. Film mulching is not only conducive to the planting of sweet potatoes, but also suitable for a variety of other crops, such as peanuts, potatoes, cotton, etc. This film mulching planting method has been widely implemented in the prior art.

[0004] With the increasing requirements for crop planting effects, some people have proposed to use double-layer film covering to further optimize planting conditions. However, in the actual operation process, double-layer film covering encountered many problems. Initially, some people tried to stack two layers of film directly on top of each other to cover the planting area, but the planting effect was not ideal. Later, it was improved to cover one layer of film first and then another layer of film. In this process, the first layer of film can still be covered with the help of equipment, but when covering the second layer of film, most of them rely on manual pulling and covering, which not only consumes a lot of time, energy and material resources, but also has difficulties when covering a single ridge. When covering two ridges at the same time, the difficulty of the operation is greatly increased. Therefore, there is an urgent need to optimize and improve the existing double-ridge double-layer film covering method to improve the film covering efficiency and planting effect. Summary of the invention

[0005] To overcome the above-mentioned defects, the embodiments of the present disclosure provide a multi-ridge double-film ridge-forming and covering machine, which solves the problem in the related art that multi-ridge land is covered with double films layer by layer twice, which consumes a lot of manpower and material resources, and the consistency of the two covering effects cannot be guaranteed.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a multi-ridge double-film ridging and covering machine, which is used to lay inner and outer films on multiple ridges, and the multi-ridge double-film ridging and covering machine includes: a frame for passing over a plurality of said ridges; A film frame, arranged at the rear end of the frame along the direction in which the frame passes, the film frame being used to place two film reels that are spaced apart and rotatably arranged in a front-to-back manner, the film reel located at the front side being used to provide the inner coating film, the film reel located at the rear side being used to provide the outer coating film, and the reel gap being formed between the two film reels; An inner film pressing arm is arranged on the frame and located between two adjacent ridges; the inner film pressing arm passes through the reel gap and is used to press the inner film downward so that the inner film adheres to the ground between the two adjacent ridges, thereby forming a cavity for heat preservation and moisture retention between the inner film and the outer film, and the cavity is located between the two adjacent ridges.

[0010] For example, in the multi-ridge double-film ridging and covering machine provided in at least one embodiment of the present disclosure, the ridge setting unit further includes: A plurality of side soil guides are obliquely arranged on the ridge-setting frame and are spaced apart along the axis direction of rotation of the tilling blade. The side soil guides are located between the tilling blade and the ridge-setting frame and are distributed on the left and right sides of the ridge. The side soil guides are used to gather the soil after rotary tillage by the tilling blade to the middle of the ridge-setting frame and to shape the side edges of the ridge.

[0011] For example, in the multi-ridge double-film ridging and covering machine provided in at least one embodiment of the present disclosure, the ridge setting unit further includes: An upper soil guide is obliquely arranged on the frame, located between the tillage blade and the ridge-fixing frame, the lower end of the upper soil guide is connected to the upper end of the side soil guide, and the upper end of the upper soil guide is higher than the upper end surface of the ridge; and is used to receive the soil thrown out after the tillage blade rotates; A soil turning plate is rotatably arranged on the frame and is located between the tillage blade and the ridge setting frame.

During the movement, the film reel 4 located on the front side of the film frame 3 starts to rotate, and the inner film 5 gradually unfolds. The inner film pressing arm 8 passes through the reel gap 7 and presses the inner film 5 downward to make it tightly attached to the ground between the two ridges 2. Subsequently, the film reel 4 located on the rear side of the film frame 3 unfolds the outer film 6, which is carried on the upper end surfaces of the two ridges 2 and covers the inner film 5, thereby forming a cavity 9 for heat preservation and moisture retention between the inner film 5 and the outer film 6, completing the laying of double ridges and double films.

[0026] like Figure 1 to Figure 9 As shown, it shows a multi-ridge double-film ridging and covering machine in one embodiment of the present disclosure.

[0027] Overall structure overview: This multi-ridge double-film ridging and covering machine is mainly composed of key components such as a frame 1, a film frame 3, and an inner film pressing arm 8. Its design purpose is to efficiently and conveniently lay inner and outer films 5 and 6 on multiple ridges 2 at the same time to improve the crop planting environment and enhance the planting effect. Take two ridges 2 as an example for explanation.

[0028] Structural design of frame 1: Frame 1 is the basic support structure of the entire ridging and film covering machine. It is usually welded with high-strength metal materials such as high-quality steel to ensure that it has sufficient strength and stability and can move smoothly over multiple ridges 2. The shape and size of frame 1 are customized according to the spacing and width of the actual ridges 2 and other components required to be carried. For example, its length should be slightly larger than the total width of multiple ridges 2 to ensure that it can completely cover the edges on both sides when covering over the ridges 2; the width needs to be determined according to the installation requirements of the film frame 3 and inner film pressure arm 8 used to ensure that each component is installed firmly and does not interfere with each other. At the same time, running wheels can be installed under the frame 1. The running wheels are generally made of rubber to increase the friction with the ground and ensure the stability of driving in the field. The running wheels should be equipped with adjustable suspension devices to adjust the height of the frame 1 from the ground according to different soil conditions and the height of the ridges 2.

[0029] Principle: The main function of the frame 1 is to provide a mobile support platform for the entire ridging and film covering machine, so that it can move smoothly above the ridge 2 to achieve the film covering operation on the ridge 2. By installing various components on the frame 1, they form an organic whole and work together. In actual operation, the ridging and film covering machine can be driven to move along the forward direction of the ridge 2 through a traction device such as a tractor, thereby completing the film covering work. This design principle is based on the basic mobile operation requirements of agricultural machinery, ensuring that each component can complete the corresponding function on a relatively stable platform.

[0030] Technical effect: The sturdy and stable frame 1 provides a reliable guarantee for the normal operation of the ridging and film covering machine, so that the entire equipment can still maintain a good working condition under complex terrain and soil conditions in the field, improves the continuity and accuracy of the film covering operation, and also extends the service life of the equipment.

[0031] Structural design of film frame 3: Along the direction of the frame 1, the film frame 3 is arranged at the rear end of the frame 1. The film frame 3 is usually composed of a metal frame, which has sufficient strength and rigidity to support the film reel 4 and withstand the tension of the film during the unfolding process. The frame structure of the film frame 3 is designed to accommodate two film reels 4 that are spaced apart and rotatably arranged in the front and back, and the axis lines of the two film reels 4 remain parallel to ensure that the film can be laid evenly and smoothly when unfolded. The film frame 3 is also equipped with an axle seat for fixing the film reel 4. The axle seat generally adopts an adjustable structure, which can be fine-tuned according to the diameter and length of different film reels 4 to ensure that the film reel 4 is firmly installed and rotates flexibly. In addition, a tension adjustment device can be set on the film frame 3, such as a tension control system composed of a combination of springs, dampers, etc., to adjust the tension of the film during the unfolding process to avoid wrinkles or breaks in the film.

[0032] Principle explanation: The function of the film frame 3 is to place and support the film reel 4 and control the unfolding process of the film. The film reel 4 on the front side provides the inner film 5, and the film reel 4 on the rear side provides the outer film 6. When the ridging and laminating machine moves on the ridge 2, the film reel 4 rotates on the film frame 3 as the film is laid. The tension adjustment device ensures that the film always maintains appropriate tension during the unfolding process, so that the film can be laid flat on the ridge 2. The two film reels 4 are spaced apart from each other and form a reel gap 7, which provides space for the inner film pressure arm 8 to pass through, so as to achieve the layered laying of the inner film 5 and the outer film 6, forming a heat-insulating and moisture-retaining cavity 9. This design principle is based on the need for precise control of the film laying process, ensuring that the double-layer film can be laid on the ridge 2 in an orderly and efficient manner.

[0033] Technical effect: The rationally designed film frame 3 ensures the stable support of the film reel 4 and the smooth unfolding of the film. The tension adjustment device effectively improves the flatness and quality of the film laying, avoiding the problem of poor coating effect caused by uneven film tension. At the same time, it creates conditions for the operation of the inner film pressure arm 8, which helps to form an ideal heat-insulating and moisture-retaining cavity 9 between the double-layer film.

[0034] Structural design of inner film pressing arm 8: inner film pressing arm 8 is arranged on frame 1 and located between two adjacent ridges 2. It is usually composed of one or more metal rods with certain elasticity and strength. The material of the metal rod is generally spring steel to ensure that it can provide sufficient pressure to make the inner film 5 adhere to the ground when pressing the inner film 5, and it can also have a certain elastic buffer when encountering uneven terrain, so as to avoid damage to the inner film 5. The shape of the inner film pressing arm 8 is designed according to the shape of the ridge 2 and the laying requirements of the inner film 5. It is generally arc-shaped or broken line-shaped, so that it can better fit the ground shape between the two adjacent ridges 2. The length of the inner film pressing arm 8 should be able to pass through the reel gap 7 between the two film reels 4, and the two ends extend to the appropriate positions on both sides of the ridge 2 to ensure that the inner film 5 can be pressed comprehensively and evenly. At the bottom of the metal rod, some soft contact parts, such as rubber pads or sponge pads, can be installed to further enhance the contact effect with the inner film 5 and improve the tightness of the attachment.

[0035] Principle: The working principle of the inner film pressing arm 8 is to use its own gravity and elasticity to press the inner film 5 downward during the movement of the ridging film covering machine. When the inner film 5 is unrolled from the film reel 4 located at the front side, the inner film pressing arm 8 passes through the reel gap 7 to press the inner film 5 to the ground between two adjacent ridges 2, so that the inner film 5 is tightly attached to the ground. In this way, when the outer film 6 unrolled from the rear film reel 4 subsequently covers the inner film 5, the outer film 6 is carried on the upper end surfaces of the two adjacent ridges 2. Then, a cavity 9 for heat preservation and moisture retention is formed between the two layers of film. The cavity 9 is located between two adjacent ridges 2, which can effectively improve the growth environment of the roots of crops. This design principle is based on the need to form a heat preservation and moisture retention space between the double layers of film, and ensures that the inner film 5 fits the ground through physical pressure, thereby achieving an ideal space structure between the double layers of film.

[0036] Technical effect: The effective pressing action of the inner film pressing arm 8 enables the inner film 5 to be closely attached to the ground, ensuring the quality of the formation of the heat preservation and moisture retention cavity 9 between the double-layer films, thereby creating a more suitable growth environment for crops. At the same time, its reasonable structural design can adapt to ridges 2 of different terrains, reduce the risk of damage to the inner film 5, and improve the success rate and overall effect of the film covering operation.

[0037] Summary of working process and technical effect: When using a multi-ridge double-film ridge-forming and film-covering machine, first tow the equipment to the ridge 2 to be covered. Driven by traction equipment such as a tractor, the ridge-forming and film-covering machine moves along the forward direction of the ridge 2. During the movement, the film reel 4 located on the front side of the film frame 3 begins to rotate, and the inner film 5 gradually unfolds. The inner film pressing arm 8 passes through the reel gap 7 and presses the inner film 5 downward so that it is tightly attached to the ground between two adjacent ridges 2. Subsequently, the film reel 4 located on the rear side of the film frame 3 unfolds the outer film 6, which is carried on the upper end surfaces of the two ridges 2 and covers the inner film 5, thereby forming a cavity 9 for heat preservation and moisture retention between the inner film 5 and the outer film 6, completing the laying of the double-ridge double film.

[0038] Through the coordinated work of various components of this ridging and film covering machine, the problems existing in the current multi-ridge double-layer film covering process are effectively solved. The frame 1 provides a stable mobile platform to ensure that the equipment can operate smoothly on the ridge 2; the film frame 3 accurately controls the expansion and tension of the film to ensure the quality of film laying; the inner film pressing arm 8 successfully achieves a close fit between the inner film 5 and the ground, forming an ideal heat-insulating and moisture-retaining cavity 9. This not only greatly improves the efficiency of double-ridge double-layer film covering, reduces the consumption of manpower, material resources and time, but also further improves the yield and quality of crops by optimizing the growth environment of crops. It has significant technical advantages and practical application value, and provides a more efficient and convenient solution for film covering operations in agricultural production.

[0039] The multi-ridge double-film ridging and film covering machine can be used for double-layer film covering of multiple ridges 2. The number of inner film pressing arms 8 is several, and an inner film pressing arm 8 is arranged between any two adjacent ridges 2. Figure 8 shown.

[0040] In some examples, the structure of the inner film pressing arm 8 is refined, and a plurality of inner film pressing wheels 10 are rotatably arranged on any inner film pressing arm 8, and the plurality of inner film pressing wheels 10 rotate coaxially or are distributed at intervals along the moving direction of the frame 1; the plurality of inner film pressing wheels 10 on the same inner film pressing arm 8 are distributed on the bottom surface of the cavity 9, so that the inner film 5 between two adjacent ridges 2 can be spread flat on the ground.

[0041] For example, Figure 1~Figure 3 and Figure 5 As shown, when in use, the inner film 5 is rolled and squeezed by the inner film pressing wheel 10 to avoid the inner film 5 being broken or scratched by hard pressing, thereby reducing the double film covering effect. The distribution form of the inner film pressing wheel 10 is appropriately adjusted according to the cross-sectional shape of the cavity 9. There are two common cross-sectional shapes of the cavity 9. The first is an inverted trapezoid, such as Figure 7~Figure 8As shown, at this time, the inner film pressing wheel 10 in the cavity 9 is selected to rotate coaxially and is spaced apart along the axis of rotation. In this example, two inner film pressing wheels 10 are selected in the cavity 9, and the two inner film pressing wheels 10 are respectively located at the ends on the left and right sides of the bottom surface of the cavity 9. While ensuring that the inner film 5 is laid flat on the ground, the structural design of the laminating machine is simplified and the convenience of using the laminating machine is improved. The second type is a V-shape. At this time, the inner film pressing wheels 10 in the cavity 9 are spaced apart along the travel direction of the frame 1. In this example, one inner film pressing wheel 10 is selected, as shown in FIG. Fig. 9 shown.

[0042] In addition, the inner film pressing wheel 10 can be replaced by a pressing block with an arc-shaped surface, the arc-shaped surface of the pressing block presses against the upper surface of the inner film 5, and the risk of scratching or rupturing the inner film 5 is reduced by the arc-shaped surface.

[0043] In some examples, the structure of the multi-ridge double-film ridging and film covering machine is optimized, and a ridge setting unit 11 is added. The ridge setting unit 11 includes a ridge setting frame 13 and a plurality of tilling knives 12. The plurality of tilling knives 12 are rotatably arranged on the frame 1, and are used to rotary till the ridge 2. The axis of rotation of the tilling knives 12 is parallel to the upper end surface of the ridge 2 and is arranged at an angle to the travel direction of the frame 1. The ridge setting frame 13 is arranged on the frame 1, located at the rear side of the tilling knives 12 and at the front side of the film reel 4, and is used to shape the ridge 2 after rotary tillage. The number of ridge setting frames 13 is preferably two, which are used to shape the two ridges 2 respectively.

[0044] For example, Figure 1~Figure 3 As shown, when working, the tillage blade 12 rotates with the power provided by the driving device, and the land to be ridged is rotary tilled by the rotation of the tillage blade 12 to achieve the effect of loosening the soil; the rotation axis of the tillage blade 12 is set at an angle with the walking direction of the frame 1, and the range of the angle is selected to be (90±30)°, preferably 90°; the middle of the ridging frame 13 has a trapezoidal shaping opening, which is small at the top and large at the bottom; the loosened soil is scraped, ridged and shaped through the shaping opening; and the continuous operation of ridging and film covering of two ridges 2 is completed at the same time. The consistency of the shaping operation of the ridge 2 is improved, and the operation efficiency of the double-layer film covering is improved.

[0045] In some examples, the structure of the ridge setting unit 11 is refined, and the ridge setting unit 11 also includes an upper soil guide 15, a soil turning plate 16, a soil cutting piece 17 and a soil returning plate 22; the upper soil guide 15 is obliquely arranged on the frame 1, located between the tillage blade 12 and the ridge setting frame 13, the lower end of the upper soil guide 15 is connected to the upper end of the side soil guide 14, and the upper end of the upper soil guide 15 is higher than the upper end surface of the ridge 2; it is used to receive the soil thrown out after the tillage blade 12 rotates; the soil turning plate 16 is rotatably arranged on the frame 1, located between the tillage blade 12 and the ridge setting frame 13, and after the soil turning plate 16 rotates, it is used to throw the soil on the upper soil guide 15 to the top of the outer film 6; the soil returning plate 22 is arranged on the frame 1, located above the film reel 4, and is used to receive the soil thrown out by the soil turning plate 16 and make the received soil fall on the outer film 6. The soil cutting piece 17 is arranged on the frame 1, and is generally in a broken line shape and is located on the rear side of the soil transfer plate 16. The soil cutting piece 17 is located on the upper side of the inner film pressure arm 8. The soil cutting piece 17 is used to guide the soil thrown out by the soil transfer plate 16 to pass through the reel gap 7 and fall on the inner covering film 5.

[0046] For example, Figure 1 to Figure 6 As shown, the number of side soil guides 14 is selected to be four, and every two side soil guides 14 form a group; with the cavity 9 as the center, the two groups of side soil guides 14 are symmetrically distributed, each group of side soil guides 14 corresponds to a ridge-setting frame 13, which is used to assist in the shaping operation of a ridge 2, and each group of side soil guides 14 is symmetrically distributed on the left and right sides of a ridge-setting frame 13; along the walking direction of the frame 1, the four side soil guides 14 are defined as side piece one, side piece two, side piece three and side piece four from left to right, and the two ridges 2 are defined as ridge one and ridge two from left to right, side piece one and side piece two are symmetrically distributed on the left and right sides of ridge one, and side piece three and side piece four are symmetrically distributed on the left and right sides of ridge two; side piece two and side piece three are fixedly connected and located in the middle of ridge one and ridge two; with the cavity 9 as the center, side piece two and side piece three are symmetrically distributed.

[0047] The side soil guide 14 includes a low section plate 23, a middle section plate 24 and an upper section plate 25 connected in sequence from bottom to top, with the walking direction of the frame 1 defined as the y-axis, the left and right extension direction of the frame 1 defined as the x-axis, and the vertical up and down direction defined as the z-axis. The low section plate 23 is generally arranged up and down, and the extension surface of the low section plate 23 is set at an angle with the xz surface and the yz surface respectively; the extension surface of the middle section plate 24 is set at an angle with the xz surface, the yz surface and the xy surface respectively, and the middle section plate 24 extends in an oblique rearward and downward direction as a whole; the upper section plate 25 is set at an angle with the xz surface and the yz surface respectively, and the extension surface of the upper soil guide 15 is set at an angle with the xz surface and the xy surface respectively, and the upper soil guide 15 extends in an oblique rearward and upward direction as a whole; Figure 4~Figure 6 As shown, the lower plate 23, the middle plate 24 and the upper plate 25 can all gather the tilled soil to the middle of the ridge 2, while the middle plate 24 can squeeze the tilled soil downward to produce a certain compaction effect on the soil and prevent excessive soil from being lifted upward.

[0048] When in use, the tiller 12 rotates to loosen the soil, and the side pieces 1 and 2 gather part of the soil to one ridge, and with the help of the lateral guide effect of the side pieces 1 and 2, the ridge 1 is shaped and compacted; the side pieces 3 and 4 gather part of the soil to the second ridge, and with the help of the lateral guide effect of the side pieces 3 and 4, the ridge 2 is shaped and compacted; at the same time, the bottom of the side pieces 2 and 3 scrapes the land to form a flat bottom surface of the cavity 9, and then with the help of the lateral soil guide effect of the side pieces 2 and 3, the soil between the ridge 1 and the ridge 2 is emptied to facilitate the laying of the inner covering film 5, and finally form a cavity 9.

[0049] The number of upper soil guides 15 is the same as that of side soil guides 14, which are defined as upper piece one, upper piece two, upper piece three and upper piece four from left to right, and are arranged one by one in correspondence with the four side soil guides 14; when the tillage blade 12 rotates, part of the soil will be thrown out obliquely upward and backward with the help of its rotational centrifugal force, and the thrown soil will fall on the upper soil guide 15. At this time, the rotating soil turning plate 16 will push the soil on the upper soil guide 15 obliquely upward and backward, and with the help of the centrifugal force generated when the soil turning plate 16 rotates, the soil on the upper soil guide 15 is thrown above the outer covering film 6 and hit on the backfilling plate 22. The backfilling plate 22 has a downwardly curved arc, and the backfilling plate 22 is used to prevent the thrown soil from splashing everywhere. At the same time, the soil thrown out by the soil turning plate 16 can fall on the upper covering film, completing the soil covering operation of the upper covering film.

[0050] The soil-turning plate 16 throws the soil of the upper piece 1 to the left side of the ridge 1; and throws the soil of the upper piece 4 to the right side of the ridge 2; the soil-turning plate 16 throws the soil on the upper pieces 2 and 3 to the top of the cavity 9, and in the process of throwing, the soil above the cavity 9 will fly to the soil-cutting piece 17, which is in a broken line shape as a whole, including a horizontal section and a vertical section connected and arranged, the horizontal section is located above the inner membrane pressure arm 8, and the vertical section is located at the rear side of the inner membrane pressure arm 8 and above the reel gap 7, and the connection between the horizontal section and the vertical section has an arc guide; the soil above the cavity 9 is moved along the horizontal direction. The soil moves along the guide of the longitudinal section, the arc guide and the vertical section, and finally this part of the soil passes through the reel gap 7 along the vertical section and falls on the upper surface of the inner covering film 5 in the cavity 9. With the help of the soil-cutting piece 17 to intercept and guide the soil, this part of the soil covers the bottom surface of the cavity 9, preventing sunlight from shining on the bottom surface of the cavity 9, and forming a layer similar to a shade cloth on the inner covering film 5, which curbs the growth of weeds under the inner covering film 5 at the bottom surface of the cavity 9, reduces the loss of soil fertility, and helps the potato seedlings to take root and grow, as well as the accumulation of nutrients in the fruit.

[0051] At the same time, the soil covering the bottom surface of the cavity 9 can press the inner film 5 downward to prevent the inner film 5 from rising upward and fitting with the outer film 6, thereby ensuring the continuous and effective existence of the cavity 9. In addition, with the help of the soil interception member 17 to retain the soil, it is possible to prevent the soil on the upper member 2 and the upper member 3 from falling on the outer film 6 above the cavity 9, and to prevent the flying soil from pressing the outer film 6 downward, causing the outer film 6 to shrink toward the position of the cavity 9, resulting in the outer film 6 being unable to completely cover the two ridges 2; at the same time, it also plays a protective role in the existence of the cavity 9.

[0052] In some examples, the multi-ridge double-film ridging and laminating machine is optimized, and a drip irrigation tape laying unit 18 is added, which includes a drip irrigation tape reel 19 and a tape guide tube 20; the drip irrigation tape reel 19 is rotatably arranged on the frame 1, located on the upper side of the film frame 3, and is used to carry and output the drip irrigation tape; the tape guide tube 20 is arranged on the frame 1, located on the lower side of the drip irrigation tape reel 19, and is configured to guide the drip irrigation tape through the tape guide tube 20, after passing through the film reel 4 distributed on the front side, and buried under the inner covering film 5. There are two drip irrigation tape reels 19, corresponding to two ridges 2 respectively.

[0053] For example, Figure 1~Figure 3 As shown, when in use, the drip irrigation tape to be laid is rolled up on the drip irrigation tape reel 19, and then the output end of the drip irrigation tape is passed through the tape guide tube 20. With the guidance of the tape guide tube 20, the drip irrigation tape bypasses the film reel 4 distributed on the front side and is laid under the inner covering film 5. As the frame 1 moves, the drip irrigation tape reel 19 starts to rotate synchronously and outputs the drip irrigation tape, so that the drip irrigation tape is gradually laid under the inner covering film 5, and multiple operations such as ridge forming 2, drip irrigation tape laying, and film covering are concentrated on the film laminating machine, realizing continuous operation and reducing the working frequency of the overall operation; at the same time, the drip irrigation is laid under the inner covering film 5, which is convenient for later precise irrigation, reduces the waste of water resources, and reduces the cost of planting management.

[0054] In some examples, the multi-ridge double-film ridging and covering machine is optimized, and a fertilizer box 21 is added. The fertilizer box 21 is arranged on the upper side of the frame 1, and a discharge port is provided at the bottom of the fertilizer box 21, and the discharge port is used to output fertilizer to the front side of the tilling blade 12.

[0055] For example, Figure 1~Figure 3 As shown, when in use, the fertilizer to be applied can be added into the fertilizer box 21. When the frame 1 is moving, the fertilizer is discharged from the discharge port and transported to the front side of the tiller blade 12 through the pipeline drainage commonly used in the prior art. As the tiller blade 12 rotates, the fertilizer is mixed into the soil. With the help of the loosening operation of the tiller blade 12, the fertilizer application operation is realized, the operation efficiency is improved, the uniformity of fertilization is improved, the fertilizer is prevented from piling up, and the problem of crop root burns is avoided.

[0056] In some examples, the connection structure between the inner membrane pressing arm 8 and the frame 1 is refined, and the inner membrane pressing arm 8 and the frame 1 are detachably hinged. The fixed section of the inner membrane pressing arm 8 and the frame 1 are hinged.

[0057] For example, Figure 1~Figure 3 and Figure 5 As shown, the inner film pressing arm 8 is generally L-shaped as a whole, including a fixed section and a film pressing section that are connected and arranged. The fixed section and the frame 1 are arranged with a detachable hinge. The film pressing section passes through the reel gap 7 into the cavity 9, and the end of the film pressing section away from the fixed section is pressed against the upper side of the inner film 5, so that the inner film 5 fits the ground; when in use, as the frame 1 moves, the inner film pressing arm 8 moves in the same direction as the frame 1. When the height of the bottom surface of the cavity 9 changes, the fixed section will swing on the frame 1, so that the end of the film pressing section away from the fixed section changes with the height change of the bottom surface of the cavity 9, thereby improving the flexibility of the inner film pressing arm 8 during operation, realizing real-time adjustment, and ensuring the fit of the inner film 5 with the ground.

Although the present disclosure 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 disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be included in the scope of the claims of the present disclosure.
