Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, and in particular to a cotton strip-tillage narrow film-laying belt sowing device and a planting method. Background Art

[0002] Cotton strip tillage is a conservation tillage technology that mainly involves local tillage of the planting rows without full tillage of the soil. For example, a strip tiller is used to loosen the soil in the planting rows, while retaining a certain amount of crop stalks between the rows. The principle is to use the loosened soil in the planting rows to provide a suitable soil environment for cotton seed germination and root growth, while the retained stalks cover the soil surface, reduce soil erosion, inhibit weed growth, and increase soil organic matter.

[0003] In order to further improve the growth environment of cotton planting, the existing technology usually lays film on the surface of the field, using the physical properties of the film to reduce soil moisture evaporation, increase soil temperature, and inhibit weed growth. For example, the film is laid with the help of a film laying machine. When the film laying machine is working in the field, it unfolds the film and covers the soil surface, and at the same time, the edges of the film on both sides are buried in the soil through a mechanical device to fix the film.

[0004] In traditional cotton shredding and returning to the field and rotary tillage and film-laying, cotton stalks are usually shredded and returned to the field directly, and rotary tillage is performed to mix the soil with the shredded cotton stalks to improve the soil structure and increase soil fertility, followed by film-laying by a film-laying machine. On the one hand, film-laying operations in the field increase the use of ground film and increase the cost of film laying; on the other hand, rotary tillage operations cut the residual film into many small fragments, and the distribution of the small fragments in the soil is extremely scattered and irregular, which greatly increases the difficulty of residual film recovery.

[0005] However, in the process of combining the strip-tillage technology with the film-laying planting technology, it is difficult for existing film-laying machines to carry out film-laying operations under the conditions of the land after strip-tillage. Especially after the land is strip-tilled, when there are standing crop stalks between the rows, it is difficult for the film-laying machine to carry out film-laying operations in the field. The standing crop stalks will interfere with the travel route of the film-laying machine. Film-laying machines are usually designed to operate on relatively flat fields without obvious obstacles. The presence of standing stalks makes it easy for the traveling wheels of the film-laying machine to be blocked, entangled or forced to deviate from the predetermined track. For example, when the traveling wheels hit the standing stalks, it may cause the machine to shake or even be unable to move forward normally, seriously affecting the continuity and efficiency of the film-laying operation. Summary of the invention

[0006] The purpose of the present invention is to provide a planting device for cotton strip planting, which can smoothly implement film laying operations while retaining crop stalks between rows, reduce film laying costs, and improve film laying efficiency.

[0007] In order to solve the above technical problems, in the first aspect, the present invention proposes a cotton strip tillage narrow film laying belt sowing device, comprising a frame, on which a bracket for connecting a traction device is provided, and further comprising a walking mechanism, a rotary tillage assembly, a belt laying assembly, a film laying assembly and a hole sower arranged on the frame in sequence; The frame is provided with a rotary tillage channel, and a passage for passing cotton stalks is provided between adjacent rotary tillage channels. The walking mechanism is arranged at the entrance of the rotary tillage channel to support the frame; The rotary tillage assembly is installed in the rotary tillage channel and is used to rotary till the ground on both sides of the cotton stalks to form a planting belt; The film laying assembly is arranged at the exit of the rotary tillage channel, and is used for performing film laying operation on the ground after rotary tillage, and the film laying assembly corresponds to the rotary tillage channel one by one; The tape laying assembly is located between the rotary tillage channel and the film laying assembly, and is used to pre-bury the drip irrigation tape in the ground before the film laying operation; The hole sower is used for sowing seeds on the planting belt after film laying. The hole sower is installed on the frame and arranged behind the film laying component.

[0008] Preferably, the walking mechanism includes a support wheel, a wheel frame and an adjusting rod, the support wheel is connected to the adjusting rod through the wheel frame, the adjusting rod is mounted on the frame, the wheel frame is embedded in one end of the adjusting rod, an overlapping portion for adjusting the height of the aisle is provided between the wheel frame and the adjusting rod, and a pair of support wheels are symmetrically arranged along the center line of the aisle.

[0009] Preferably, the film laying assembly includes a connecting frame and a film roller for winding the ground film, the film roller spans above the planting belt, the film roller is connected to the frame through the connecting frame, and the axial length of the film roller is greater than the width of the rotary tillage channel.

[0010] Preferably, a power component for providing power to the rotary tillage assembly is provided on the frame, and the output end of the power component is connected to the rotary tillage assembly through a transmission structure, the transmission structure includes a first transmission box and a second transmission box, the power component is installed on the frame and is located above the aisle, and the first transmission box and the second transmission box are symmetrically arranged along the center line of the aisle.

[0011] Preferably, the tape laying assembly includes a support frame and a roller for winding the drip irrigation tape, the roller is installed on the top of the frame through the support frame, and a guide mechanism for guiding the drip irrigation tape is provided on the support frame.

[0012] Preferably, the guide mechanism comprises a guide wheel and a sleeve, and the guide wheel is installed below the sleeve.

[0013] Preferably, the hole seeders correspond one to one with the planting belts.

[0014] Preferably, the mulch film is a degradable mulch film.

[0015] Preferably, a film pressing mechanism is provided between the film laying assembly and the hole seeder. The film pressing mechanism is mounted on a frame and is configured to compact the ground after film laying as the ground rises and falls.

[0016] In a second aspect, the present invention further proposes a planting method using the above-mentioned cotton strip tillage narrow film laying belt sowing device, comprising the following steps: Start the traction equipment to drive the frame into the cotton field so that the aisle of the frame crosses above the cotton stalks. According to the height of the cotton stalks, adjust the walking mechanism to form a stable support for the frame; When the traveling mechanism drives the frame to move forward, the rotary tillage assembly performs rotary tillage operation on the ground on both sides of the cotton stalks in the rotary tillage channel to form a planting belt. During the rotary tillage process, the aisles between adjacent rotary tillage channels are used to retain the cotton stalks. As the frame continues to move forward, when the planting belt after rotary tillage reaches the belt laying assembly position, the belt laying assembly pre-buries the drip irrigation belt into the ground. The laying position of the drip irrigation belt is determined according to the planting needs and subsequent irrigation planning to ensure that the water supply of the drip irrigation belt effectively covers the planting area; The film laying component performs film laying operation on the planting belt at the exit of the rotary tillage channel, so that the ground film is evenly covered on the planting belt and closely adheres to the ground, forming a narrow film laying belt corresponding to the rotary tillage channel one by one; After the film is laid, the seed drill starts to work and sows the cotton seeds on the planting belt after the film is laid according to the predetermined plant spacing and row spacing.

[0017] Compared with the prior art, the cotton strip tillage narrow film-laying belt sowing equipment and planting method provided by the present invention have the following outstanding substantial features and significant improvements: 1. The cotton strip tillage and narrow film laying sowing equipment has a rotary tillage channel and aisles between adjacent rotary tillage channels for passing cotton stalks. In the strip tillage operation, the cotton stalks are retained. On the one hand, the energy consumption and equipment loss in the link of crushing the cotton stalks are reduced; on the other hand, the cotton stalks remain in the field for a certain period of time, which can play a certain role in wind prevention and soil consolidation, help maintain the stability of the field soil structure, and reduce the occurrence of soil wind erosion. Compared with the traditional cotton crushing and returning to the field and rotary tillage and film laying sowing, which are relatively extensive and disturb the soil over a large area, the soil disturbance range is smaller and the degree is lighter, which is more conducive to protecting the soil ecological environment and maintaining the stability of the microbial community in the soil, etc., creating a good and sustainable soil condition for cotton growth.

[0018] 2. The cotton strip-tillage narrow film-laying and sowing equipment adopts a unique frame design. A rotary tillage channel and aisles between adjacent rotary tillage channels are set on the frame for the cotton stalks to pass through, which effectively solves the problem of the stalks interfering with the travel route of the film-laying machine, allowing the equipment to operate stably under such special strip-tillage land conditions, greatly improving the adaptability of the equipment to complex field environments, avoiding problems such as machine bumps and inability to move forward normally due to obstruction by the stalks, and ensuring the continuity and efficiency of the film-laying operation. The walking mechanism, rotary tillage assembly, strip-laying assembly, film-laying assembly and hole-seeding device are integrated on one frame, and the layout and coordinated work between the components are carefully designed. From rotary tillage to form a planting belt, to strip laying, film laying and then to sowing, the links between the links are tight and precise, reducing the errors caused by equipment conversion and repositioning, and improving the quality and efficiency of the overall planting operation.

[0019] 3. This planting method utilizes a rotary tillage component to perform rotary tillage operations only on the ground on both sides of the cotton stalks in the rotary tillage channel to form a planting belt. This is a precise rotary tillage mode that can minimize the disturbance of the soil in non-planting areas, better maintain the original air permeability, water retention and fertility of the soil, provide more suitable soil conditions for cotton growth, and help subsequent planting management operations to be accurately positioned on the planting belt. Compared with traditional full-field rotary tillage, it reduces unnecessary rotary tillage area and workload, and can effectively improve the efficiency of rotary tillage operations while ensuring that the soil in the planting belt meets the sowing requirements. The film laying component performs film laying operations on the planting belt at the exit of the rotary tillage channel, so that the ground film is evenly covered on the planting belt and fits tightly to the ground, forming a narrow film laying belt corresponding to the rotary tillage channel one by one. Compared with the traditional film laying method, the ground film's functions of warming, moisture conservation, and weed suppression are more fully utilized, and the ground film coverage range is accurately matched with the planting belt, reducing the redundancy of ground film use, saving both the film laying cost and the difficulty of residual film recovery.

DETAILED DESCRIPTION

[0030] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-Figure 5 As shown, a cotton strip-tillage narrow film-laying and sowing equipment is proposed in an embodiment of the present invention, which aims to smoothly implement film-laying operations while retaining crop stalks between rows during cotton strip-tillage planting, thereby reducing film-laying costs and improving film-laying efficiency.

[0032] The cotton strip tillage narrow film laying belt sowing equipment proposed in the embodiment of the present invention has a unique frame design, and a rotary tillage channel and aisles between adjacent rotary tillage channels are set on the frame for the cotton stalks to pass through, which effectively solves the problem of the stalks interfering with the travel route of the film laying machine, so that the equipment can operate stably under this special strip tillage land condition, greatly improves the adaptability of the equipment to complex field environments, avoids the problems of machine bumps and inability to move forward normally caused by the obstruction of the stalks, and ensures the continuity and efficiency of the film laying operation. In addition, the walking mechanism, rotary tillage component, belt laying component, film laying component and hole sowing device are integrated on a frame, and the layout and coordinated work between the components are carefully designed. From rotary tillage to form a planting belt, to belt laying, film laying and then to sowing, the connection between the various links is tight and precise, which reduces the errors caused by equipment conversion and repositioning, and improves the quality and efficiency of the overall planting operation.

[0033] like Figure 1 Combination Figure 2 As shown, a cotton strip tillage and narrow film laying belt sowing device comprises a frame 1, on which a bracket 2 for connecting a traction device is arranged. The cotton strip tillage and narrow film laying belt sowing device also comprises a walking mechanism 3, a rotary tillage component 4, a belt laying component 5, a film laying component 6 and a hole sower 7 which are sequentially arranged on the frame 1.

[0034] like Figure 1 Combination Figure 4 As shown, a rotary tillage channel 8 is provided on the frame 1. A passage 9 for passing the cotton stalks is provided between adjacent rotary tillage channels 8. The walking mechanism 3 is arranged at the entrance of the rotary tillage channel 8 to support the frame 1.

[0035] like Figure 3 Combination Figure 4 As shown, the rotary tillage assembly 4 is installed in the rotary tillage channel 8, and is used to rotary till the ground on both sides of the cotton stalks to form a planting belt.

[0036] like Figure 2 Combination Figure 3 As shown, the film laying assembly 6 is arranged at the exit of the rotary tillage channel 8, and is used for performing film laying operation on the ground after rotary tillage. The film laying assembly 6 corresponds to the rotary tillage channel 8 one by one.

[0037] like Figure 3 Combination Figure 5 As shown, the tape laying assembly 5 is located between the rotary tillage channel 8 and the film laying assembly 6, and is used to pre-bury the drip irrigation tape into the ground before the film laying operation.

[0038] like Figure 2As shown, the hole sower 7 is used to sow seeds on the planting belt after film laying. The hole sower 7 is installed on the frame 1 and arranged behind the film laying assembly 6. The hole sower 7 corresponds to the planting belt one by one. The hole sower 7 can work closely with the layout of the planting belt without the need for additional adjustment or calibration, reducing the pause and waiting time during the sowing process. When the equipment is moving in the field, it can sow seeds continuously and stably, greatly increasing the sowing area per unit time, especially in large-scale cotton planting operations, it can significantly shorten the sowing cycle and improve agricultural production efficiency.

[0039] Among them, the rotary tillage component 4 only performs rotary tillage operations on the ground on both sides of the cotton stalks in the rotary tillage channel 8 to form a planting belt. This belongs to the precision rotary tillage mode, which can minimize the disturbance of the soil in the non-planting area, better maintain the original air permeability, water retention and fertility of the soil, and provide more suitable soil conditions for cotton growth.

[0040] The film laying component 6 carries out film laying operation on the planting belt at the exit of the rotary tillage channel 8, so that the ground film covers the planting belt evenly and fits tightly to the ground, forming a narrow film laying belt corresponding to the rotary tillage channel 8 one by one. Compared with the traditional film laying method, the ground film's warming, moisture conservation, weed suppression and other functions are more fully utilized. The ground film coverage range is accurately matched with the planting belt, reducing the redundancy of ground film use, saving both the film laying cost and reducing the difficulty of residual film recovery.

[0041] like Figure 3 As shown, the walking mechanism 3 includes a supporting wheel 31, a wheel frame 32 and an adjusting rod 33. The supporting wheel 31 is connected to the adjusting rod 33 through the wheel frame 32. The adjusting rod 33 is installed on the frame 1. The wheel frame 32 is embedded in one end of the adjusting rod 33. An overlapping portion for adjusting the height of the aisle 9 is provided between the wheel frame 32 and the adjusting rod 33. A pair of supporting wheels 31 are symmetrically arranged along the center line of the aisle 9.

[0042] In this way, the overlapping portion between the wheel frame 32 and the adjustment rod 33 is used to adjust the height of the aisle 9, and can be flexibly and accurately adjusted according to the actual height of the cotton stalks. In cotton planting areas with different growth conditions or varieties, the height of the stalks will vary. This adjustable design ensures that the aisle 9 can always properly cross the top of the cotton stalks during the movement of the frame 1, which not only avoids the instability of the frame 1 affecting the operation due to the aisle 9 being too high, but also prevents the aisle 9 from being too low and causing unnecessary damage or interference to the cotton stalks, so that the equipment can adapt to a variety of cotton planting scenarios.

[0043] For example, a row of equally spaced adjustment holes is provided on the adjustment rod 33 along its length direction, and a positioning pin that can cooperate with the adjustment hole is provided at the portion where the wheel frame 32 is connected to the adjustment rod 33. When the height of the aisle 9 needs to be adjusted, the positioning pin is pulled out from the current adjustment hole, and then the wheel frame 32 is moved up or down according to the height requirement of the cotton stalks, so that the overlapping portion of the wheel frame 32 and the adjustment rod 33 changes, thereby changing the height of the aisle 9. When the wheel frame 32 is moved to a suitable position, the positioning pin is inserted into the corresponding adjustment hole, thereby fixing the relative position of the wheel frame 32 and the adjustment rod 33, and realizing precise adjustment of the height of the aisle 9.

[0044] Alternatively, a screw-nut adjustment structure is used between the adjustment rod 33 and the wheel frame 32. A vertical screw is fixed on the adjustment rod 33, and the screw passes through the nut on the wheel frame 32. By rotating the nut, the nut moves up and down on the screw, driving the wheel frame 32 to move up and down relative to the adjustment rod 33, thereby changing the size of the overlapping portion between the wheel frame 32 and the adjustment rod 33, and adjusting the height of the aisle 9. Tightening nuts can be set on both sides of the nut. When the height is adjusted to a suitable level, tighten the tightening nuts to prevent the nuts from loosening during operation, thereby ensuring the stability of the relative position of the wheel frame 32 and the adjustment rod 33.

[0045] like Figure 2 As shown, the film laying assembly 6 includes a connecting frame 61 and a film roller 62 for winding the ground film. The film roller 62 spans above the planting belt. The film roller 62 is connected to the frame 1 through the connecting frame 61. The axial length of the film roller 62 is greater than the width of the rotary tillage channel 8. Such an arrangement can ensure that the ground film can completely cover the planting belt area after rotary tillage, so that the edge of the ground film can better fit the soil, reduce the gap at the edge, reduce the adverse effects of interference from external environmental factors on cotton growth, further enhance the function of the ground film in moisture conservation and temperature increase, and provide more favorable conditions for cotton growth.

[0046] like Figure 1 Combination Figure 4 As shown, a power component 10 for providing power to the rotary tillage assembly 4 is provided on the frame 1. The output end of the power component 10 is connected to the rotary tillage assembly 4 through a transmission structure. The transmission structure includes a first transmission box 11 and a second transmission box 12. The power component 10 is mounted on the frame 1 and is located above the aisle 9. The first transmission box 11 and the second transmission box 12 are symmetrically arranged along the center line of the aisle 9.

[0047] In this way, the power component 10 is installed above the aisle 9 on the frame 1, which effectively utilizes the space above the frame 1 and avoids occupying too much space below the frame 1 or other key operation areas, thereby leaving more ample layout space for components such as the rotary tillage component 4, the belt laying component 5, the film laying component 6 and the hole seeder 7, making the overall structure of the equipment more regular, reducing the size and floor space of the equipment, improving the flexibility and passability of the equipment during field operations, and facilitating operation in narrow or irregularly shaped plots.

[0048] In addition, the first transmission box 11 and the second transmission box 12 are symmetrically arranged along the center line of the aisle 9, which corresponds to the symmetrical structure of the entire equipment and helps to maintain the balance of the equipment during power transmission. The symmetrical layout can evenly distribute power to both sides of the rotary tillage component 4, reducing problems such as equipment overloading, vibration, or unstable operation caused by unbalanced power. During the movement of the equipment, stable power transmission can ensure that the rotary tillage component 4 performs rotary tillage operations on the ground on both sides of the cotton stalks at a consistent speed and torque, thereby improving the quality of rotary tillage and making the soil conditions of the planting belt more uniform.

[0049] like Figure 2 Combination Figure 3 As shown, the tape laying assembly 5 includes a support frame 51 and a roller 52 for winding the drip irrigation tape. The roller 52 is installed on the top of the frame 1 through the support frame 51. A guide mechanism for guiding the drip irrigation tape is provided on the support frame 51. The guide mechanism is used to accurately guide the drip irrigation tape. During the movement of the equipment, the drip irrigation tape is released from the roller 52. After being constrained and positioned by the guide mechanism, it can be laid on the ground according to a predetermined path and angle, effectively avoiding the problems of deviation, twisting or winding of the drip irrigation tape during the laying process, and ensuring that the drip irrigation tape is accurately located on one side of the planting belt.

[0050] like Figure 3 As shown, the guide mechanism includes a guide wheel 53 and a sleeve 54, and the guide wheel 53 is installed below the sleeve 54. The guide wheel 53 is installed below the sleeve 54, and is used to contact the drip irrigation belt and accurately position and guide it. When the drip irrigation belt is released from the roller 52, the guide wheel 53 constrains the drip irrigation belt to move along a predetermined straight track by virtue of its rolling friction with the drip irrigation belt, ensuring that the drip irrigation belt is laid accurately. It effectively avoids the situation where the drip irrigation belt moves in a serpentine manner or deviates from the planting belt range, so that each section of the drip irrigation belt can accurately correspond to the planting position of the cotton, ensuring the uniformity and effectiveness of irrigation.

[0051] The sleeve 54 is used to provide a stable constraint channel for the drip irrigation belt, and its specific inner diameter and shape are designed to fit closely with the drip irrigation belt. When the drip irrigation belt passes through the sleeve 54 during the laying process, the sleeve 54 effectively limits the lateral and vertical displacement of the drip irrigation belt, ensuring that the drip irrigation belt always remains in the predetermined laying direction, greatly reducing the possibility of the drip irrigation belt flipping or twisting due to external factors (such as wind, equipment vibration or terrain undulation).

[0052] According to some preferred embodiments of the present invention, the mulch film is selected as a degradable mulch film. Compared with traditional plastic mulch films, which are difficult to degrade naturally after use, a large amount of them remain in the soil, destroying the soil structure, affecting the soil's aeration, water permeability and microbial activity, leading to a decline in soil fertility, and causing long-term and irreversible harm to the agricultural ecological environment. Degradable mulch films can decompose on their own within a certain period of time, effectively reducing the pollution of the mulch residues to the soil and the environment, helping to protect the health and balance of the soil ecosystem, and creating good environmental conditions for the sustainable development of agriculture. Degradable mulch films are particularly suitable for strip-tillage planting patterns. When changing seasons and sowing, there is no need to recover the residual film, which greatly reduces the workload.

[0053] When a cotton strip tillage narrow film-laying and sowing device proposed in an embodiment of the present invention is used, the traction device is started to drive the frame 1 into the cotton field, so that the aisle 9 of the frame 1 spans above the cotton stalks. According to the height of the cotton stalks, the walking mechanism 3 is adjusted to form a stable support for the frame 1.

[0054] When the traveling mechanism 3 drives the frame 1 to move forward, the rotary tillage assembly 4 performs rotary tillage operations on the ground on both sides of the cotton stalks in the rotary tillage channel 8 to form a planting belt. During the rotary tillage process, the aisles 9 between adjacent rotary tillage channels 8 are used to retain the cotton stalks.

[0055] As the frame 1 continues to move forward, when the planting belt after rotary tillage reaches the position of the belt laying component 5, the belt laying component 5 pre-buries the drip irrigation belt into the ground. The laying position of the drip irrigation belt is determined according to the planting needs and subsequent irrigation planning to ensure that the water supply of the drip irrigation belt effectively covers the planting area.

[0056] The film laying component 6 performs film laying operation on the planting belt at the exit of the rotary tillage channel 8, so that the ground film is evenly covered on the planting belt and fits tightly to the ground, forming a narrow film laying belt corresponding to the rotary tillage channel 8 one by one.

[0057] After the film is laid, the hole sower 7 starts to work and sows the cotton seeds on the planting belt after the film is laid according to the predetermined plant spacing and row spacing.

[0058] The above-mentioned planting method utilizes the rotary tillage component 4 to perform rotary tillage operations only on the ground on both sides of the cotton stalks in the rotary tillage channel 8 to form a planting belt. It belongs to the precision rotary tillage mode, which can minimize the disturbance of the soil in the non-planting area, better maintain the original air permeability, water retention and fertility of the soil, provide more suitable soil conditions for cotton growth, and help subsequent planting management operations to be accurately positioned on the planting belt.

[0059] Compared with the traditional whole-field rotary tillage, it reduces unnecessary rotary tillage area and workload, and can effectively improve the efficiency of rotary tillage while ensuring that the soil in the planting belt meets the sowing requirements. The film laying component 6 performs film laying on the planting belt at the exit of the rotary tillage channel 8, so that the ground film is evenly covered on the planting belt and fits tightly to the ground, forming a narrow film laying belt corresponding to the rotary tillage channel 8. Compared with the traditional film laying method, the functions of the ground film such as warming, moisture conservation, and weed suppression are more fully utilized. The coverage range of the ground film is accurately matched with the planting belt, reducing the redundancy of the ground film, saving both the film laying cost and reducing the difficulty of residual film recovery.

[0060] For example, a cotton strip tillage and narrow film laying and sowing equipment proposed in an embodiment of the present invention uses a degradable ground film with a width of 30-40 cm and a thickness of 0.01 mm to carry out single-row and single-row or single-row and double-row cotton upright stalk film laying and sowing on the seed strip after strip tillage. Compared with traditional cotton crushing and returning to the field and rotary tillage and film laying planting, it saves 43% of ground film usage per mu and reduces the ground film investment cost by 8%-26%, effectively solving the problem of ground film pollution.

[0061] A cotton strip-tillage narrow film-laying and sowing equipment proposed in an embodiment of the present invention retains the cotton stalks in the strip-tillage operation by arranging a rotary tillage channel 8 and a passage 9 between adjacent rotary tillage channels 8 for passing the cotton stalks. On the one hand, it reduces the energy consumption and equipment loss in the link of crushing the cotton stalks. On the other hand, the rotary tillage channel 8 and the passage 9 between adjacent rotary tillage channels 8 arranged on the frame 1 for the cotton stalks to pass through effectively solve the problem of the standing stalks interfering with the travel route of the film-laying machine, so that the equipment can operate stably under such special strip-tillage land conditions, greatly improves the adaptability of the equipment to complex field environments, ensures the continuity and efficiency of the film-laying operation, and improves the quality and efficiency of the overall planting operation.

[0062] like Figure 6 As shown, a film pressing mechanism 13 is also provided between the film laying assembly 6 and the hole sower 7. The film pressing mechanism 13 is mounted on the frame 1 and arranged behind the film roller 62. The film pressing mechanism 13 is configured to compact the ground after film laying as the ground rises and falls.

[0063] In this way, the film pressing mechanism 13 compacts the ground after film laying as the ground rises and falls, which can effectively enhance the fit between the ground film and the ground, significantly reduce the evaporation and loss of soil moisture, and create a more moist soil environment for seed germination and crop growth. Especially in arid and semi-arid areas, the moisture conservation effect is crucial to improving seed germination rate and crop survival rate, thereby helping to increase crop yields and agricultural production benefits.

[0064] In addition, the reasonable layout of the film pressing mechanism 13 installed on the frame 1 and located behind the film roller enables it to compact the ground in time after film laying, ensuring the continuity and efficiency of the film laying and film pressing processes, optimizing the entire agricultural sowing and film covering operation process, improving the operation quality and work efficiency of agricultural machinery, and effectively saving time and labor costs in large-scale agricultural production.

[0065] like Figure 6 Combination Figure 7 As shown, the film pressing mechanism 13 includes a film pressing roller 131 and a telescopic sleeve 132. A pair of telescopic sleeves 132 are arranged in parallel on the frame 1. The film pressing roller 131 is installed between the pair of telescopic sleeves 132, and the side wall of the film pressing roller 131 is in contact with the ground film. The fixed end of the telescopic sleeve 132 is connected to the frame 1. The telescopic end of the telescopic sleeve 132 is connected to the end of the film pressing roller 131. Under the self-excitation of the ground, the film pressing roller 131 applies a force to the telescopic sleeve 132 with the ups and downs of the ground, driving the telescopic sleeve 132 to move up and down relative to the ground, and its reaction force compacts the ground after film laying.

[0066] Among them, the film pressing roller 131 is in direct contact with the ground film and compacts the ground through the linkage of the telescopic sleeve 132 when the ground is undulating. The film pressing roller 131 can flexibly adjust the contact pressure and angle with the ground according to the actual ground conditions. The setting of the telescopic sleeve 132 enables the film pressing roller 131 to have a certain buffering and avoidance ability when encountering ground obstacles. When the film pressing roller 131 encounters protrusions such as stones and soil in the field during its movement, the telescopic sleeve 132 can shrink accordingly, so that the film pressing roller 131 can smoothly cross the obstacles without damaging the equipment or the ground film. It not only improves the durability of the film pressing mechanism 13, reduces the equipment maintenance cost and downtime, but also ensures the continuity of the film laying operation.

[0067] The telescopic sleeve 132 can also adjust the pressure of the film pressing roller 131 on the ground by adjusting its own telescopic degree according to factors such as different soil textures, film materials and thicknesses. For example, in loose sandy soil, the film pressing force can be appropriately reduced to prevent excessive pressing that affects soil permeability; while in compact clay areas, the pressure can be appropriately increased to ensure that the film fits tightly. In this way, while meeting the film pressing requirements under different operating conditions, it also helps to extend the service life of the film, reduce the film loss cost, and further improve the economic efficiency of agricultural production.

[0068] For example, Figure 8 As shown, a compression spring 134 is disposed in the telescopic sleeve 132. The compression spring 134 is used to absorb and buffer impact force. Under different terrain conditions, the undulation of the ground and the compactness of the soil will vary. The compression spring 134 can automatically adjust the telescopic amount of the telescopic sleeve 132 according to actual conditions, thereby adjusting the pressure of the film pressing roller 131 on the ground.

[0069] like Figure 7 As shown in FIG. 1 , a groove 133 is provided on the side wall of the laminating roller 131. Fig. 9 As shown, the ground after compaction by the film pressing roller 131 is slightly convex in the middle and low on both sides, so that the compacted ground forms a structure with the seed belt surface 14 in the middle and grooves 15 on both sides. During irrigation under the film, the seed belt surface is slightly higher than the ground on both sides. When sufficient irrigation is performed, excess water will be discharged to the grooves 15 on both sides, and the salt in the soil will be discharged to both sides along with the flow of water, which can effectively reduce the salt content at the root of the seed belt, create a relatively low-salt growth environment for the plants, and reduce the damage of salt to the root system of the plants, which is greatly beneficial to the healthy growth of the plants, improve the survival rate and yield of crops, and improve the efficiency and quality of agricultural planting as a whole.

In addition to the above embodiments, the present invention may also have other implementation modes. For those skilled in the art, any technical solutions formed by any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
