[0021] The present invention mainly has the following beneficial effects:

[0022] The intelligent rice film-covering and hole-free dry direct seeding integrated machine proposed by the present invention realizes the intelligent integration of rice dry direct seeding equipment;

[0023] During operation, the ridging and seeding mechanism quickly creates parallel and continuous ridges and ditches, compacts and shapes the soil converging at the ridge tops and ditch bottoms to form standard ridge shapes with smooth ridge tops and ditch bottoms. The seed guide grooves correspondingly dry direct seed rice in the ditches to form seeding belts and cover the soil. The seed dropping positions are accurate and the soil covering is uniform;

[0024] The watering mechanism diverts water and waters the seeding belts, significantly reducing the water consumption. Combined with the slurry scraping blades to level the bottom of the ditches after watering, the rice seeds are fully in contact with and adhered to the soil, providing a good environment for the germination and rooting of the rice seeds. The plastic film closely adheres to the surface of the seeding belts, effectively improving the film-piercing seedling emergence rate;

[0025] The film-covering mechanism makes the plastic film adhere to the seeding belts formed by dry direct seeding rice seeds in the ditches, narrows the plastic film wider than the mechanical seeding width, and makes the plastic film closely adhere to the undulating surface seeding belts. There is no gap between the rice seeds and the plastic film, ensuring that the rice seeds germinate, pierce through the film and emerge as seedlings, with a high seedling emergence rate;

[0026] The soil covering and fetching mechanism combines the soil covering and fetching with the ditch opening, ridging and film-covering processes, automatically collects part of the soil generated by ditch opening, pulverizes it into fine soil during the transmission process, and evenly covers the seeding belts and the plastic film respectively. The thickness of the soil covering on the seeding belts is uniform, effectively improving the film-piercing seedling emergence rate. After the plastic film is covered with soil, it closely adheres to the undulating surface seeding belts. There is no gap between the rice seeds and the plastic film, ensuring that the rice seeds germinate, pierce through the film and emerge as seedlings, effectively improving the film-piercing seedling emergence rate;

[0027] In summary, in the working process of the dry direct seeding integrated machine, the processes such as ditch opening, ridging, seeding, watering, film covering and soil covering are well coordinated, with high intelligence and automation levels. The ditch opening and ridging are flat, with good water collection capacity, and water consumption is saved. The rice seeds germinate, pierce through the film and emerge as seedlings, with a high seedling emergence rate, good growth and high yield. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Figure 1 It is a schematic structural diagram of the intelligent rice film mulching and non - perforated dry direct seeding all - in - one machine proposed by the present invention. Figure 2 It is a schematic internal structure diagram of the intelligent rice film mulching and non - perforated dry direct seeding all - in - one machine proposed by the present invention. Refer to the attached Figure 2 , in this embodiment, the following are provided on the machine tool frame 201:

[0054] A ridging and seeding mechanism 60, which is used to form a plurality of parallel and continuous ridges a and grooves b on the field and dry - direct - seed rice seeds in the grooves b to form a seeding belt; Figure 4 It is a schematic structural diagram of the ridging and seeding mechanism in one embodiment of the present invention Figure 1 ; Figure 5 It is a schematic structural diagram of the ridging and seeding mechanism in one embodiment of the present invention Figure 2 . Refer to the attached Figure 4-5 , in this embodiment, the ridging and seeding mechanism 60 includes: a ditch - ridge plate, a front soil - retaining plate 601, and a seed guide groove 607;

[0055] Among them, the front soil retaining plate 601 is arranged on the side of the furrow and ridge plate close to the moving body 10 and inclines towards the moving body 10 from bottom to top. A number of ridge forming parts 602 and furrow bottom forming parts 603 are formed on the furrow and ridge plate alternately in parallel to form a number of parallel and continuous ridges and furrows on the field. There are a number of seed guide grooves 607, which are respectively arranged on the furrow bottom forming parts 603 and penetrate through the furrow bottom forming parts 603 to form a sowing belt for dry direct-seeding of rice seeds in the furrow and uniformly cover the soil. And a number of soil taking holes 605 corresponding to the positions of the furrow bottom forming parts 603 are formed on the side of the front soil retaining plate 601 close to the moving body 10, and a soil taking and covering mechanism 80 for taking soil to cover the sowing belt is assembled in the soil taking holes 605.

[0056] In this embodiment, a seed box 90 is arranged in a matching manner, and a number of seed dropping ports corresponding to the positions of the seed guide grooves 607 are arranged at the bottom end thereof to dry direct-seed rice seeds into the furrow b. A fertilizer box 103 is arranged in a matching manner, and a number of seed dropping ports corresponding to the positions of the seed guide grooves 607 are arranged at the bottom end thereof to simultaneously sprinkle chemical fertilizers into the furrow b.

[0057] In the technical solution of the above embodiment, the inclined setting of the front soil retaining plate 601 and the ridge forming parts 602 and furrow bottom forming parts 603 formed on the furrow and ridge plate constitute a "boat bottom" shape. The moving body 10 carries the machine tool system to operate in the field. During the movement, a number of parallel and continuous ridges a and furrows b are formed on the field through the ridge forming parts 602 and furrow bottom forming parts 603 alternately in parallel. And the ridge forming parts 602 and furrow bottom forming parts 603 compact and form the soil converging at the ridge top and furrow bottom at the soil gathering ports to form a standard ridge shape, with the ridge top and furrow bottom being smooth. The seed guide grooves 605 correspondingly dry direct-seed the rice in the seed box 90 into the furrow b to form a sowing belt and uniformly cover the soil. The seed dropping position is accurate, effectively improving the film-piercing emergence rate.

[0058] At the same time, during the process of opening the furrow and ridge by the furrow and ridge sowing mechanism 60, some soil will accumulate on the front soil retaining plate 601 corresponding to the furrow bottom forming part 603. At this time, the lower end of the soil taking cylinder 802 collects this part of the soil generated by the furrow opening and transmits it through the spiral soil conveying rod to the upper part of the sowing belt after dry direct-seeding and film covering, and discharges it through the first soil dropping port 8021, uniformly covering it on the covered plastic film, making the plastic film closely adhere to the undulating surface sowing belt, with no gap between the rice seeds and the plastic film, ensuring that the rice seeds germinate and pierce through the film to emerge, and effectively improving the film-piercing emergence rate.

[0059] Furthermore, the upper end of the seed guide groove 607 is connected through a through connection with a soil dropping guide groove 608, and the other end of the soil dropping guide groove 608 is connected through a through connection with the soil taking cylinder 801. Refer to the appendix Figure 5, a second soil dropping port 8022 for connecting the soil dropping guide groove 608 is formed on the barrel body of the soil taking barrel 802; wherein, the soil dropping guide groove 608 is arranged at the downstream position of the seed dropping port to separate the seed guide groove 607 into a lower seed dropping port 609 located upstream and a lower soil dropping port 610 located downstream.

[0060] In the technical solution of the above embodiment, the seed guide groove 607 is separated into a lower seed dropping port 609 located upstream and a lower soil dropping port 610 located downstream by the soil dropping guide groove 608, so as to ensure that the sown seeds are covered with a layer of soil about 0.5 cm thick and are further flattened by the bottom groove forming part 603, ensuring that the soil covering thickness is uniform and consistent, and effectively improving the film piercing and seedling emergence rate.

[0061] Further, referring to the appendix Figure 4 , side retaining plates 608 are symmetrically arranged on both sides of the furrow and ridge plate to form the outer edge of the soil gathering part 604 at the edge position; and further, the upper parts of both edges of the furrow and ridge plate are effectively supported by the support members 204 to prevent the furrow and ridge plate from deforming.

[0062] Further, referring to the appendix Figure 4-5 , a plurality of soil gathering parts 604 corresponding to the ridge forming parts 602 are formed on one side of the front retaining plate 601 close to the moving body 10. The soil gathering part 604 is a funnel or semi - funnel - shaped structure with a gradually narrowing opening from the bottom groove forming part 603 to the ridge forming part 602, so that the soil dug out from the furrow b is gathered and stacked on the ridge a to form a ridge. The ridge forming part 602 compacts and forms the soil converging at the ridge top of the soil gathering part 604 to form a standard trapezoidal ridge; and a trenching tool 611 for forming a standard smooth groove is fixed at the bottom end of the bottom groove forming part 603. The trenching tool 611 includes an integrally formed arrowhead part and an arrow tail part. The arrowhead part is an acute - angled isosceles triangle with the acute angle facing the side of the moving body 10; in this embodiment, the arrow tail part is a rectangular structure and its end extends to the upstream position of the seed guide groove 607, effectively reducing the resistance of the furrow and ridge opening.

[0063] The watering mechanism 70 is arranged downstream of the ridging and sowing mechanism 60 and is used for guiding the irrigation water to irrigate the sowing belt and leveling the irrigated sowing belt;

[0064] In some of the embodiments, referring to the appendix Figure 6 and 7 , the watering mechanism 70 includes: a water tank 701, an irrigation pipeline 703 and scraping blades 705; wherein, the input end of the irrigation pipeline 703 is connected to the water tank 701 through penetration, and its output end has several and is respectively arranged corresponding to the furrows to water the dry direct - seeding rice seeds; the scraping blades 705, with a plurality of them, are respectively arranged at the output ends of several irrigation pipelines 703 to guide the watering path to the dry direct - seeding rice seeds and level the irrigated sowing belt.

[0065] In this embodiment, referring to the attached Figure 6 and 7 , the irrigation pipeline 703 includes: a water delivery pipe 7031, whose input end penetrates and connects to the bottom wall of the water tank 701 and is equipped with a water pump 7035; a water distribution valve 7032, which has one input end and multiple output ends, and its input end is connected to the output end of the water delivery pipe 7031; a plurality of sub-water pipes 7033, whose input ends are respectively connected to the output ends of the water distribution valve 7032, and the output ends of the plurality of sub-water pipes 7033 are respectively arranged corresponding to the ditches to water the sowing belts.

[0066] In this embodiment, referring to the attached Figure 6 and 7 , the slurry scraping blade 705 includes a diversion part 7051 and a leveling part 7052. Among them, the diversion part 7051 is fixed above the ditch and is arranged to match the water outlet path of the irrigation pipeline 703 to divert water to the sowing belt in the ditch; the leveling part 7052 is in a parabolic arc shape and has elasticity, and the lowest end of the parabolic arc contacts the ground to scrape and level the watered sowing belt.

[0067] In the technical solution of the above embodiment, the mobile body 10 carries the implement system to operate in the field. The ridging and sowing mechanism 60 opens continuous furrows and ridges, and directly sows dry rice seeds in the ditch b to form a sowing belt and evenly covers the soil. The irrigation pipeline 703 sucks the irrigation water in the water tank 701 to the upper part of the sowing belt in the ditch b and flows to the covered sowing belt after being diverted by the slurry scraping blade 705, without washing out the rice seeds of the covered sowing belt. After the sowing belt is watered, the slurry scraping blade 705 moves with the machine body to scrape and level the bottom of the watered ditch b. The water used for watering is concentrated and uniform. At the same time, compared with the traditional irrigation method, the water consumption is greatly reduced. At the same time, after the slurry scraping blade 705 levels and processes, the rice seeds are fully in contact with the soil and adhered, providing a good environment for the germination and rooting of the rice seeds. The plastic film is closely adhered to the surface of the sowing belt, effectively improving the emergence rate through the film.

[0068] In this embodiment, the capacity of the water tank is set to 120 liters. Adjust the flow rate of each water distribution valve 7032 to be equal, then a tank of water can meet the sowing needs of 0.6 mu of fields. At the same time, the flat mouth of the faucet 7034 is perpendicular to the walking direction, and the inclination angle between the faucet 7034 and the horizontal ground is 70°, and the height from the ground is about 5 cm; after the slurry scraping blade 705 is fixed obliquely, the inclination angle between the upper diversion part 7051 and the horizontal ground is 70°, and the lowest end of the parabolic arc of the leveling part 7052 touches the ground;

[0069] In the technical solution of the above embodiment, the flat-mouthed nozzle-shaped water outlet faucet 7034 can effectively increase the width of the water outlet and evenly water the sowing belt, and the flat-mouthed nozzle-shaped water outlet faucet 7034 can effectively adapt to the diversion part 7051 of the scraper 705 to divert water to the dry direct-seeded rice seeds in the ditch b. The water used for watering is concentrated and uniform. After the watering is completed, the leveling part 7052 elastically contacts the ground at the bottom of the ditch b and scrapes and smoothes the sowing belt, providing good conditions for the subsequent bonding of the ground film.

[0070] The film covering mechanism 30 is provided downstream of the watering mechanism 70 and is used to lay a continuous film on the sowing belt and press the film to narrow it and adhere to the sowing belt;

[0071] In some of these embodiments, see the attached Figure 8 and 9 The film covering mechanism 30 includes: a film roller bracket 302, which is arranged on the machine frame 201; a ground film roller 301, which is wound with ground film and is vertically arranged above a plurality of ridges and furrows and is detachably rotatably mounted on the film roller bracket 302; a wheel frame 306, which is arranged on the side of the machine frame 201 away from the moving direction of the mobile body 10; a plurality of pressing wheels 305, which are rotatably mounted on the wheel frame 306 and are used to press the ground film onto the sowing belt; a plurality of film collecting rollers, which are horizontally and obliquely mounted on the wheel frame 306 and roll in contact with the lower end of the ground film roller 301, and a plurality of film collecting rollers are respectively matched and rolled in the furrow;

[0072] The free end of the ground film passes through a plurality of pressing wheels 305 and is rolled out by the pressing wheels 305 and then laid and pressed on the sowing belt. The ground film is then narrowed by the horizontally inclined film collecting roller so that the ground film adheres to the sowing belt.

[0073] In this embodiment, refer to the accompanying drawings. Figure 8 and 9 The film collecting roller includes: at least one middle wheel 304, which rolls in the groove in the middle; several film guide inclined wheels 303, which roll symmetrically in the grooves on both sides of the middle wheel 304, and the lower ends of the film guide inclined wheels 303 are tilted horizontally outward to press and collect the side edges of the ground film.

[0074] In the technical solution of the above embodiment, the mobile body 10 carries the implement system to operate in the field. The ridging and seeding mechanism 60 forms continuous furrows and ridges and directly sows dryland rice seeds in the furrow b to form a seeding belt. Subsequently, the pressing wheel 305 and the film collecting roller located downstream of the operation roll in the furrow b. The film roll 301 rotates synchronously with the film collecting roller under its own weight to release the film. The free end of the film bypasses the pressing wheel 305 and is drawn by the pressing wheel 305 and then laid and pressed on the formed furrows and ridges, so that the film adheres to the dryland direct-seeded rice seeds in the furrow b. Subsequently, the horizontally and obliquely installed film collecting roller narrows the film so that the film adheres to the seeding belt, and there is no gap between the rice seeds and the film. When the rice seeds germinate, they break through the film and emerge, and the emergence rate is high.

[0075] Specifically, the middle wheel 304 is placed perpendicular to the ground, and the film guiding inclined wheels 303 are installed inclined outward respectively when installed. The rotation direction of the film collecting roller is the same as the traveling direction. The width of the contact plane of the middle wheel 304 with the ground is about 5 cm; the film roll 301 is arranged directly above the middle wheel 304 and the film guiding inclined wheels 303.

[0076] In this embodiment, the number (N) of the film collecting rollers provided is the same as the number of seeding rows and is installed corresponding to the seeding rows; when the number of seeding rows of the seeder is odd, the middle one of the wheels is set as the middle wheel 304, which is placed vertically and has an inclination angle of 90° with the ground. The film guiding inclined wheels 303 are symmetrically installed on both sides of the middle wheel 304 respectively and are inclined outward respectively. The inclination angles of the film guiding inclined wheels 303 on both sides are symmetrically opposite to the ground; when the number of seeding rows of the seeder is even, the two middle wheels are set as the middle wheels 304, and the film guiding inclined wheels 303 are symmetrically installed on both sides of the middle wheels 304 respectively and are inclined outward respectively, and the inclination angles with the ground are symmetrically opposite.

[0077] Furthermore, in this embodiment, the total narrowing amount L of the film by the film collecting roller depends on the inclination angle α (the left one is the left inclination angle and the right one is the right inclination angle) of the film guiding inclined wheel 303 and the diameter D of the film guiding inclined wheel 303, and D is greater than L, and the maximum inclination angle is less than 90°. When the inclination angle of the film guiding inclined wheel 303 is equal to 90°, there is no film collecting effect. When the inclination angle of the film guiding inclined wheel 303 is greater than 90°, it becomes reverse-side film collecting;

[0078] If the film is collected by the half-cycle movement of the film guiding inclined wheel 303, and the primary narrowing amount of the outermost film guiding inclined wheel 303 is L and the diameter of the film guiding inclined wheel is D, then the inclination angle of the outermost first film guiding inclined wheel 303 is: The inclination angle of the second film guiding inclined wheel 303 from the outermost to the inside is:

[0079] The inclination angle of the third film guiding inclined wheel 303 from the outermost to the inside is:

[0080]

[0081] Therefore, if the total number of film guide wheels is N, the inclination angle of the nth film guide inclined wheel from the outermost to the innermost is: If the number of film guide wheels is odd, the middle film collecting roller is the middle wheel 304, and its inclination angle is 90°.

[0082] Further, refer to the attached Figure 8 and 9 The film collecting roller of this embodiment has a diameter of 25 cm and a wheel width of 6 cm. It has three film guide wheels, the middle wheel 304 is placed vertically, and the film guide inclined wheels 303 on both sides are tilted outwards, with a horizontal tilt angle of 82°. After assembly, the film collecting roller can press the ground film into the ground surface by about 1 cm, so that the ground film is attached to the sowing belt formed by the dry direct-seeding rice seeds in the furrow b. There is no gap between the rice seeds and the ground film. When the rice seeds germinate, they penetrate the film and emerge, with a high emergence rate.

[0083] In this embodiment, Figure 10 As shown, the film roller bracket 302 is hinged to the tool frame 201 so that the ground film roller 301 contacts the film collecting roller, and both ends of the interior of the film roller bracket 302 are provided with an adjusting arm 307 that can be retracted and fixed to adapt to the film width of the ground film roller 301 and replace the ground film roller 30; the adjusting arm 307 includes: an adjusting screw 3071, which is threadedly inserted into the free end of the film roller bracket 302, and its bolt end is located on the outside of the film roller bracket 302 and is fixed with a manual adjustment knob; a roller positioning arm 3072, which is arranged at the other end of the adjusting screw 3071; a step portion 3073, which is fixedly installed on the side of the roller positioning arm 3072 close to the adjusting screw 3071; wherein, the roller positioning arms 3072 of the two adjusting arms 307 are respectively inserted into the interior of the two ends of the ground film roller 301 to provide support to the ground film roller 301.

[0084] In the technical solution of the above embodiment, the manual adjustment knobs at the ends of the two adjustment arms 307 are rotated for adjustment, and the distance between the two adjustment arms 307 can be adjusted by rotating the threads. On the one hand, the ground film roller 301 can be removed and replaced when there is sufficient distance. On the other hand, by adjusting the distance, it can be freely adjusted and adapted according to the width of the ground film roller 30 to ensure that the ground film roller 30 does not deviate during rotation.

[0085] In this embodiment, Figure 8-9 As shown, the wheel frame 306 is hinged on the tool frame 201, and the wheel frame 306 and the tool frame 201 are connected by a plurality of tension springs, so that the film collecting roller maintains a stable pressure with the ground so that the ground film adheres to the sowing belt.

[0086] The soil covering mechanism 80 has one end arranged on the side of the ridging and sowing mechanism 60 close to the mobile body 10 to collect part of the soil produced by furrowing, and the other end arranged on the side of the ridging and sowing mechanism 60 away from the mobile body 10 to crush and discharge the collected soil and cover the sowing belt and the ground film respectively.

[0087] In some of these embodiments, referring to the appendix Figure 11 and 12 , the soil covering and fetching mechanism 80 includes: a plurality of soil fetching cylinders 802, which are correspondingly arranged above the ditch. The lower end of the soil fetching cylinder 802 is not closed and is internally provided with a spiral soil conveyor rod. One end of the spiral soil conveyor rod is installed on the machine frame 201 through a fixed bracket 801, and the other end extends obliquely downward into the ditch on the side of the ridging and seeding mechanism 60 close to the mobile body 10; a plurality of transmission members 803, which are respectively fixed on the free ends of the spiral soil conveyor rods on the side close to the machine frame 201; a driving motor 804, which is installed on the machine frame 201 and is in transmission connection with the plurality of transmission members 803 to drive the plurality of spiral soil conveyor rods to rotate synchronously to fetch and convey soil; a plurality of first soil dropping openings 8021, which are respectively opened at the positions corresponding to the ditch above on the side of the soil fetching cylinder 802 close to the transmission member 803 to discharge the soil and fall into the ditch to cover the plastic film.

[0088] In this embodiment, referring to the appendix Figure 11 and 12 , a second soil dropping opening 8022 connecting the soil dropping guide groove 608 is opened on the barrel body of the soil fetching cylinder 802. The upper end of the seed guide groove 607 is connected to the soil dropping guide groove 608 in a through manner, and the other end of the soil dropping guide groove 608 is connected to the second soil dropping opening 8022 in a through manner;

[0089] In the technical solution of the above embodiment, during the ditch and ridge formation process of the ridging and seeding mechanism 60, some soil will accumulate on the front soil retaining plate 601 corresponding to the ditch bottom forming part 603. At this time, the lower end of the soil fetching cylinder 802 collects this part of the soil generated by the ditch opening, advances it through the spiral soil conveyor rod, pulverizes it and then transports it above the sowing belt after dry direct seeding and film covering, and discharges it through the diversion of the first soil dropping opening 8021. Subsequently, the soil dropping guide groove 608 divides the seed guide groove 604 into a seeding opening 607 located upstream and a soil dropping opening 608 located downstream, so as to ensure that the sown seeds are covered with a layer of finely crushed soil about 0.5 cm thick and are further flattened by the ditch bottom forming part 603, ensuring that the soil covering thickness is uniform, and effectively improving the film penetration and emergence rate.

[0090] In this embodiment, referring to the appendix Figure 11 and 12, the first soil dropping opening 8021, with a number of them, are respectively opened at positions above the corresponding trench b on the side of the soil fetching cylinder 802 close to the transmission member 803 to discharge soil into the trench b to cover the plastic film; the soil fetching and covering mechanism 80 further includes: a soil dropping diversion chute 805, fixed at the lower side of the soil fetching cylinder 802 corresponding to the position of the first soil dropping opening 8021 to divert soil into the trench b to cover the plastic film; a chute support 806 for supporting the soil dropping diversion chute 805 is provided below the soil dropping diversion chute 805. Specifically, in this embodiment, the diameter of the soil fetching cylinder 802 is 10 cm, and it forms an angle of 30° with the horizontal ground. The diameter of the spiral soil conveying rod is 8 cm, and the exposed length at the front end of the soil fetching cylinder 802 is 2 cm. The soil dropping diversion chute 805 is connected to the soil fetching cylinder 802 at a right angle and is inclined backward and downward;

[0091] In the technical solution of the above embodiment, the soil dropping diversion chute 805 discharges the soil at the position of the first soil dropping opening 8021 and evenly covers the plastic film laid on the seeding belt by the film covering mechanism 30, making the plastic film closely adhere to the undulating surface seeding belt. There is no gap between the rice seeds and the plastic film, ensuring that the rice seeds germinate through the film and emerge, effectively improving the film penetration and emergence rate; in this embodiment, the soil covering thickness on the plastic film is about 1 cm. The plastic film is a 0.01 mm fully biodegradable plastic film, and the film width is 90 cm - 95 cm. When the rice seeds germinate, they penetrate through the film and emerge, with a high emergence rate.

[0092] In one of the embodiments, referring to the appendix Figure 12 , a connected soil dividing flow channel groove 807 is integrally formed on the soil dropping diversion chute 805, and the output end of the soil dividing flow channel groove 807 is located above the ridge a; a soil dividing regulating valve 808 for diverting soil to the soil dividing flow channel groove 807 is provided in the soil dropping diversion chute 805 to limit the soil layer thickness covering the rice seeds; the soil dividing regulating valve 808 includes an L-shaped groove body. One end of the L-shaped groove body is rotatably installed on the inner bottom wall of the soil dropping diversion chute 805, and a limiting rotating shaft is provided at the other end of the L-shaped groove body, and the limiting rotating shaft is rotatably installed in an arc-shaped through hole opened on the inner bottom wall of the soil dropping diversion chute 805;

[0093] In the technical solution of the above embodiment, by adjusting the rotation angle of the soil dividing regulating valve 808, the amount of soil flowing into the trench b can be effectively limited, ensuring that the soil covering thickness on the plastic film is about 1 cm. The excess soil discharged through the first soil dropping opening 8021 is diverted and discharged onto the ridge a to avoid excessive and uneven soil covering thickness.

[0094] In some of the embodiments, referring to the appendix Figure 1 、 2And 13, also includes a film cutting mechanism 40, which is arranged downstream of the film covering mechanism 30, and is used to automatically cut the ground film when the machine system changes the working path, including: a cross bar 402, which is arranged perpendicular to the laying direction of the ground film; an electric push rod 401, the number of which is at least one, which is fixed on the machine frame 201 and the telescopic end is arranged at the upper end of the cross bar 402 to drive the cross bar 402 to rise and fall; a film cutting heating wire 404, which is arranged in parallel on the cross bar 402 through two film cutting brackets 403. When the cross bar 402 descends, the film cutting heating wire 404 is energized and heated to heat-melt and cut off the ground film.

[0095] In the technical solution of the above embodiment, the mobile body 10 carries the tool system to the end of a path in the field. When it is necessary to change to the next working path, the lifting component 203 drives the tool frame 201 to lift upward, and then lifts the tool system to move upward. At this time, the mulch between the laid mulch and the mulch roller 301 is pulled and tilted and suspended in the air; the film-cutting heating wire 404 is energized and preheated, and then the electric push rod 401 pushes the cross bar 402 and the film-cutting heating wire 404 to descend to perform thermal melting and cut off this section of tilted and suspended mulch. The fracture of the mulch is clean and neat, which improves the quality of mulching and sowing, and increases the yield and benefits.

[0096] In this embodiment, Figure 13 As shown, the film cutting mechanism 40 also includes: a film cutting start limiter 407, which is fixed on the tool frame 201 and has an external detection contact, and the detection contact is arranged on the travel of the lifting path of the tool frame 201; a main control box 406, which has a built-in PLC controller for receiving the start and end signals of the film cutting start limiter 407 to automatically control the working status of the electric push rod 401 and the film cutting heating wire 404.

[0097] In the technical solution of the above embodiment, when the lifting component 203 drives the tool frame 201 to lift upward, the detection contact contacts the lifting action of the tool frame 201 and sends feedback to the main control box 406. The main control box 406 issues a first control instruction to start the film-cutting heating wire 404 for preheating. In this embodiment, the preheating time is 5 seconds. When the lifting action reaches the end of the stroke, the main control box 406 issues a second control instruction to start the electric push rod 401, which automatically pushes the film-cutting heating wire 404 down to perform thermal melting and cut the inclined and suspended ground film, thereby realizing film cutting automation.

[0098] It can be understood that when the telescopic end of the electric push rod 401 reaches the end of the stroke, the film-cutting heating wire 404 can complete the cutting of the ground film, and the telescopic end immediately carries the film-cutting heating wire 404 to rise and reset, and at the same time, according to the editing of the PLC controller in the main control box 406, the power-on time of the film-cutting heating wire 404 is timed and set. In this embodiment, the overall power-on time is 8S, that is, preheating for 5S and descending and cutting for 3S. After the cutting is completed, the film-cutting heating wire 404 is powered off.

[0099] In one embodiment, referring to the attached Figure 13 , on one of the film cutting brackets 403, there is an electric heating wire tension spring 405, and the electric heating wire tension spring 405 is insulatedly connected to the film cutting electric heating wire 404 to tension the film cutting electric heating wire 404, ensuring that the film cutting electric heating wire 404 cuts the plastic film flatly.

[0100] The above embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
