Description

Technical Field

[0001] The present invention mainly relates to the field of agricultural machinery seeding equipment, and specifically relates to a film mulching and direct seeding integrated machine. Background Art

[0002] With the development of agricultural planting mechanization and control technology, modern agricultural planting technology has rapidly developed towards large-scale mechanization. The film mulching planting technology for crops is a modern planting technology with functions of weed suppression, moisture retention, soil moisture conservation, reduced fertilization, and reduced pesticide application. After adopting the film mulching planting technology, the growth of non-plant crops such as weeds can be effectively inhibited, and it can also play roles in moisture retention, soil moisture conservation, reducing the growth of pests, and reducing the amount of fertilization. If a fully biodegradable film is used for film mulching planting, while having the above functions, there is no need for film recycling, and the degradation and decomposition of the film can also have beneficial effects on improving the soil environment.

[0003] In some hilly farmlands in the south, it is not suitable for the planting operations of large agricultural machinery. Especially in the planting and seeding seasons in the south, it is often the rainy season. The rainy and soft clay farmlands make it easy for large agricultural machinery to get stuck during operation, which will delay the farming season and affect the best seeding time. It is imperative to develop a small-sized integrated crop film mulching planting machine suitable for such farmlands.

[0004] In addition, after the film mulching seeder lays the film on the ground, it is also necessary to fix the film to prevent the film from being blown disorderly; at the field head, the film mulching seeder needs to turn, and at this time, the film needs to be cut. Therefore, in order to enrich the mechanical functions and improve the mechanical convenience, a film fixing mechanism, a film cutting mechanism, etc. can also be set. For the seeding tooling, in order to meet the planting requirements of different crops, it is necessary to adjust the seeding row spacing and plant spacing. Therefore, it can be considered how to achieve the adjustment of the seeding row spacing and plant spacing. Summary of the Invention

[0005] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution significantly different from the existing technology. It mainly provides a film mulching and direct seeding integrated machine to adapt to the farmlands in hilly areas.

[0006] The technical solution adopted by the present invention to solve the above technical problems is as follows:

[0007] A film mulching and direct seeding integrated machine includes an installation frame, a film laying tooling, and a seeding tooling. The film laying tooling includes a film cylinder, a film pressing roller, and a mounting seat plate for carrying the film cylinder and the film pressing roller and connecting to the installation frame. The film pressing roller is rotatably connected to the mounting seat plate through a first swing arm rod, and a sensor is provided on the film pressing roller; the seeding tooling includes a seeder and an installation groove plate for carrying the seeder and connecting to the installation frame. The seeder is rotatably connected to the installation groove plate through a second swing arm member.

[0008] Further, the film pressing roller includes a central shaft and a plurality of oval spheres sleeved on the central shaft. The central shaft is detachably connected to the free end of the first swing arm rod, and the oval spheres can rotate freely around the central shaft.

[0009] Further, mounting seat plates are connected to both ends of the film cylinder. The film pressing roller and the mounting seat plates are located on the same side of the film cylinder. Along the length direction of the film cylinder, film supporting tooth plates extending towards the side where the film pressing roller is located are equidistantly installed at the bottom of the film cylinder. The film supporting teeth are located below the film pressing roller. A rectangular long hole for pulling out the film is formed on one side of the film cylinder facing the film pressing roller.

[0010] Further, the mounting frame includes a main beam, a machine head connecting frame, and a machine head connecting arm for connecting to the main machine head. The machine head connecting frame is installed above the main beam. The machine head connecting arm is connected to one side of the machine head connecting frame. The mounting seat plate is connected to the main beam, and the film cylinder and the film pressing roller are arranged parallel to the main beam. The film cylinder and the machine head connecting arm are located on the same side of the main beam. The seeder is located on the side of the main beam facing away from the film cylinder.

[0011] Further, the mounting groove plate is installed at one end of the movable bracket. The movable bracket includes a horizontally arranged rod frame, a lifting kit connected to one side of the end of the horizontally arranged rod frame, and a telescopic rod connected between the horizontally arranged rod frame and the lifting kit. The mounting groove plate is connected to the side of the end of the horizontally arranged rod frame facing away from the lifting kit. The fixed end of the lifting kit is fixedly connected to the mounting frame, and the lifting end of the lifting kit is connected to the horizontally arranged rod frame. The two ends of the telescopic rod are respectively hinged to the horizontally arranged rod frame and the lifting kit.

[0012] Further, a long sleeve that is horizontally slidably connected to the horizontally arranged rod frame is fixed to the lifting end of the lifting kit. A short sleeve that is horizontally slidably connected to the horizontally arranged rod frame is provided on the hinge member at the end of the telescopic rod connected to the horizontally arranged rod frame.

[0013] Further, a film fixing mechanism is provided between the film laying tooling and the seeding tooling. The film fixing mechanism includes two sets of disk shovels, connecting rods, and third swing arm rods respectively located at the edge positions on both sides of the film covering. One end of the third swing arm rod is rotatably connected to the mounting frame, and a sleeve that is vertically arranged and sleeved on the connecting rod is provided at the free end of the third swing arm rod. A fastening member for locking the connecting rod is provided on the sleeve. The disk shovel is detachably installed at the lower end of the connecting rod. An inclined first spring is connected between the third swing arm rod and the fixed part of the lifting kit.

[0014] Further, a film cutting mechanism is provided on one side of the film laying tooling. The film cutting mechanism includes a film cutting knife located on the side of the film pressing roller facing away from the film cylinder, a connecting plate fixedly connected to the mounting seat plate, a fourth swing arm rod rotatably connected to the connecting plate, and a control cable connected to the main machine head. The film cutting knife is arranged parallel to the film cylinder. An inclined second spring is provided between the fourth swing arm rod and the connecting plate. The control cable is connected to a control lever installed on the machine head.

[0015] Further, the seeders are arranged in a row. A connecting sleeve for connecting two adjacent second swing arm members is provided between every two adjacent second swing arm members, and the second swing arm member at the end side is rotatably connected to the mounting groove plate.

[0016] Further, the seeder includes a hollow wheel type feeder and duckbill type seeding openings arranged at equal intervals on the circumferential surface of the hollow wheel type feeder. There are various specifications of the seeder, and different numbers of duckbill type seeding openings are provided on the seeders of different specifications.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) The film laying tooling of the present invention includes a film pressing roller, and the film pressing roller is hinged through a first swing arm rod. The seeding tooling includes a seeder, and the seeder is hinged through a second swing arm member. When used in hilly areas, both the film pressing roller and the seeder can swing up and down according to the height of the ground under the action of gravity, so that the film covering and direct seeding integrated machine can better adapt to the undulating ground; moreover, a sensor is provided on the film pressing roller. The moving amount of the film pressing roller swinging up and down according to the height of the ground can be detected by the sensor and fed back to the main machine head. Then, the operator manipulates the telescopic oil cylinder through the control handle according to the information provided by the sensor to control the film covering and direct seeding integrated machine to move up and down, so that the height difference between the installation frame and the ground is always kept consistent, thereby ensuring the seeding depth during direct seeding. Therefore, the present invention can be well applied to the fields in hilly areas.

[0019] (2) In the optimized scheme of the present invention, for rainy and wet soft clay fields, the film pressing roller adopts an elliptical sphere, which has a certain buoyancy in paddy fields, always keeps the film pressing roller above the ground, and at the same time transmits the ground height information to the main machine head control system through the sensor to control the height, avoiding the phenomenon of mud pushing caused by getting stuck in the softer mud ground. Then, the present invention can adapt to rainy season wet soft clay fields (even paddy fields).

[0020] (3) The film mulching and direct seeding machine provided by the present invention can be used for film mulching and direct seeding in dry fields and also in paddy fields. In the present invention, both the film pressing roller and the disc plow are installed in a detachable manner. As described above, an elliptical sphere for the film pressing roller can adapt to paddy fields. After replacing the film pressing roller, the film pressing roller has a certain pressure on the ground to ensure the fit of the film to the ground, preparing for the seeding of the subsequent seeding tooling, and thus can adapt to use in dry fields. For the disc plow, when directly seeding in paddy fields, a film pressing plow is used for the disc plow. The film pressing plow can press the film edges on both sides of the film into the soil to fix the film and make the film have a certain tension, facilitating the seeding by the seeder. When directly seeding in dry fields, a soil covering plow is used for the disc plow. The soil covering plow can shovel the soil to the film edge to press the film, facilitating the seeding by the seeder.

[0021] (4) The present invention is provided with a film tube. During application, the film roll is installed inside the film tube, and the film tube can protect the film from being contaminated before the film mulching operation. Moreover, the film roll can rotate freely inside the film tube, and only one person is required for installation, saving labor costs.

[0022] (5) In the optimized solution of the present invention, a connecting sleeve for connecting two adjacent second swing arm members is provided between every two adjacent second swing arm members. During use, by replacing connecting sleeves of different lengths, the spacing of the seeders can be adjusted, thereby achieving the effect of adjusting the seeding row spacing according to requirements. Moreover, there are various specifications of seeders, and different numbers of duckbill-shaped seeding openings are provided on different specifications of seeders. By replacing different specifications of seeders according to requirements, the seeding plant spacing can be adjusted. Then, the present invention can pre-adjust the seeding row spacing and plant spacing according to the seeding operation requirements.

[0023] (6) In the optimized solution of the present invention, a film cutting mechanism is provided. When the main engine head needs to turn at the end of the field, first use the film cutting mechanism to cut the film, then lift the film mulching and direct seeding machine to turn around. After turning, place the film mulching and direct seeding machine on the ground and continue seeding. This meets the actual needs. Moreover, along the length direction of the bottom of the film tube, film supporting tooth plates extending towards the side where the film pressing roller is located are equidistantly installed. The film supporting tooth plates are located below the film pressing roller. During use, the film extending from the film tube passes between the upper part of the film supporting tooth plates and the lower part of the film pressing roller. When the main engine head lifts the film mulching and direct seeding machine, the film supporting tooth plates will lift the film to prevent the film from being scattered and affecting the laying of the film.

[0041] Embodiment 1

[0042] Please refer specifically to the attached Figures 1-5 , a film mulching and direct seeding integrated machine, which includes an installation frame, a film laying tooling and a seeding tooling.

[0043] The installation frame includes a main beam 10, a head connecting frame 11 and a head connecting arm 12 for connecting to the main head of the host. The main beam 10 is the supporting beam of the whole device. For the structure of the main beam 10, please refer specifically to the attached Figure 6 ; The head connecting frame 11 is installed above the middle position of the main beam 10. For the structure of the head connecting frame 11, please refer specifically to the attached Figure 6 ; The head connecting arm 12 is connected to one side of the head connecting frame 11. The head connecting arm 12 includes an upper arm of the head connecting arm and a lower arm of the head connecting arm; all power comes from the main head of the host. The main head of the host can lift and lower this film mulching and direct seeding integrated machine through a hydraulic device (a telescopic oil cylinder in this embodiment), and can control the height of the direct seeding machine from the working ground through a control handle to ensure the seeding depth during direct seeding. The film mulching and direct seeding integrated machine can be directly connected to the main head of an existing ordinary transplanter (after removing the transplanting tray) and then can be used for field operations.

[0044] Please refer specifically to the attached Figure 7, the film laying tooling includes a film roll 1, a film pressing roller 2, and a mounting seat plate 3 for carrying the film roll 1 and the film pressing roller 2 and connecting to the mounting rack. Both ends of the film roll 1 are connected to the mounting seat plate 3, and the mounting seat plate 3 is connected to the main beam 10. The film roll 1 and the head connecting arm 12 are located on the same side of the main beam 10. A rectangular long hole 101 for pulling out the film is formed on one side of the film roll 1 facing the film pressing roller 2. A film roll is installed inside the film roll 1, and the film roll can rotate freely inside the film roll 1, facilitating the pulling out of the film from the rectangular long hole 101 during the film covering operation; the film pressing roller 2 is rotatably connected to the mounting seat plate 3 through a first swing arm rod 4. During use, the film pressing roller 2 adheres to the ground under the action of gravity and can swing up and down according to the height of the ground (realized by the first swing arm rod 4 rotating around its hinge end); a sensor is provided on the film pressing roller 1. While the film pressing roller 2 swings up and down according to the height of the ground, the amount of up and down movement is detected by the sensor and fed back to the main machine head. Then, the operator controls the telescopic oil cylinder through the control handle according to the information provided by the sensor to make the film covering direct seeding machine move up and down, so as to ensure the seeding depth during direct seeding; the film pressing roller 2 and the mounting seat plate 3 are located on the same side of the film roll 1, and the film roll 1, the film pressing roller 2, and the main beam 10 are arranged in parallel.

[0045] Specifically, the film pressing roller 2 includes a central shaft 201 and a plurality of elliptical spheres 202 sleeved on the central shaft 201. The elliptical spheres 202 can rotate freely around the central shaft 201. The elliptical spheres 202 are made of non-metallic materials such as plastic or polyurethane, with a lower density, having a certain buoyancy in paddy fields, always keeping the central shaft 201 above the ground, and at the same time transmitting the ground height information to the main machine head control system through the sensor to control the height, avoiding the phenomenon of mud pushing caused by getting stuck in a softer mud ground. The central shaft 201 is detachably connected to the free end of the first swing arm rod 4. When sowing on a harder dry land ground, the film pressing roller 2 can be conveniently replaced, so that the film pressing roller 2 has a certain pressure on the ground to ensure the fitting of the film and the ground, and prepare for the seeding of the subsequent seeding tooling.

[0046] Please refer to the attached Figure 8 , the seeding tooling includes a seeder 6, a mounting groove plate 7 for carrying the seeder 6, and a movable bracket 13 connecting the mounting rack and the mounting groove plate 7. A row of the seeders 6 are all rotatably connected to the mounting groove plate 7 through second swing arm members 8, and the axis of the seeder 6 is rotatably connected to the second swing arm members 8. The seeder 6 is located on the side of the main beam 10 facing away from the film roll 1. During use, the seeder 6 adheres to the ground under the action of gravity and can swing up and down according to the height of the ground (realized by the second swing arm members 8 rotating around the mounting groove plate 7).

[0047] Specifically, the movable support 13 includes a horizontally arranged rod frame 131, a lifting kit 132 connected to one end side of the horizontally arranged rod frame 131, and a telescopic rod 133 connected between the horizontally arranged rod frame 131 and the lifting kit 132. The mounting groove plate 7 is connected to one end side of the horizontally arranged rod frame 131 facing away from the lifting kit 132. The fixed end of the lifting kit 132 is fixedly connected to the main beam 10 by bolts, and the lifting end of the lifting kit 132 is connected to the horizontally arranged rod frame 131. Both ends of the telescopic rod 133 are hinged to the horizontally arranged rod frame 131 and the lifting kit 132 respectively. The lifting adjustment of the horizontally arranged rod frame 131 can be realized by the telescopic adjustment of the lifting kit 132, and the locking of the horizontally arranged rod frame 131 can be realized by the fasteners (tightening bolts) on the lifting kit 132. Moreover, a long sleeve 134 which is horizontally slidably connected to the horizontally arranged rod frame 131 is fixed at the lifting end of the lifting kit 132, and a short sleeve 135 which is horizontally slidably connected to the horizontally arranged rod frame 131 is provided on the hinge piece at the end of the telescopic rod 133 connected to the horizontally arranged rod frame 131. By the horizontal movement of the horizontally arranged rod frame 131, the distance between the seeder 6 and the main beam 10 can be adjusted, and the position of the horizontally arranged rod frame 131 can be locked by the fasteners on the long sleeve 134 and the short sleeve 135. Generally speaking, the lifting and horizontal movement adjustment of the horizontally arranged rod frame 131 can adapt to different seeding requirements.

[0048] A film fixing mechanism is provided between the film laying tooling and the seeding tooling. Please refer to the attached Figure 9 and Figure 10 emphatically. The film fixing mechanism includes two sets of disc shovels 14, connecting rods 15 and third swing arm rods 16 respectively located at the two side edges of the film covering. One end of the third swing arm rod 16 is rotatably connected to the main beam 10. During use, the disc shovel 14 abuts against the ground under the action of gravity and can swing up and down according to the height of the ground (realized by the rotation of the third swing arm rod 16 around its hinge end). An inclined first spring 17 is connected between the third swing arm rod 16 and the fixed part of the lifting kit 132. The elastic reset action of the first spring 17 can promote the efficient reset of the third swing arm rod 16. A sleeve which is vertically arranged and sleeved on the connecting rod 15 is provided at the free end of the third swing arm rod 16, and a fastener for locking the connecting rod 15 is provided on the sleeve. By adjusting the relative position of the connecting rod 15 in the sleeve, the height adjustment of the disc shovel 14 can be realized, so that the set depth of the disc shovel 14 acting on the ground can be achieved. The disc shovel 14 is detachably installed at the lower end of the connecting rod 15. The disc shovel 14 includes two types: a film pressing shovel and a soil covering shovel. When direct seeding in paddy fields, the film pressing shovel is adopted. The film edges on both sides of the film can be pressed into the soil by the film pressing shovel to fix the film and make the film have a certain tension, so as to facilitate the seeding of the seeder. When direct seeding in dry fields, the soil covering shovel is adopted. The soil covering shovel can shovel the soil to the film edge to press the film tightly, so as to facilitate the seeding of the seeder.

[0049] The application process is as follows: The main machine head and the above-mentioned film-covering direct seeding machine are integrated to work. When not working, the main machine head lifts the film-covering direct seeding machine, and it can move freely in the field and on the road; when working, the film-covering direct seeding machine is put down for film covering and seeding. The main machine head operates the hydraulic device to place the direct seeding machine on the ground of the direct seeding field. When the main machine head moves forward, it drives the direct seeding machine forward. The film of the film roll can smoothly extend freely under the drive of the main machine head, the film pressing roller 2 and the seeder 6. The film roll rotates freely in the film cylinder 1 for unwinding. The film pressing roller 2 presses the film on the ground to realize film laying; subsequently, the disk shovels 14 on both sides act on the edge of the film to fix the film edge, so as to prevent the film from being blown away by the wind and make the film tense in the width direction, facilitating the seeder 6 to punch holes in the film; then, the seeder punches holes in the film while rolling, and at the same time directly sows seeds in the holes.

[0050] Specifically, when used in farmland in hilly areas, first, the film pressing roller 2, the disk shovels 14, and the seeder 6 all swing up and down according to the height of the ground (the film pressing roller 2 realizes rotation around its hinge end through the first swing arm rod 4, the disk shovels 14 realize rotation around its hinge end through the third swing arm rod 16, and the seeder 6 realizes rotation around the mounting groove plate 7 through the second swing arm member 8), so that the film-covering direct seeding machine of the present invention can better adapt to the undulating ground; and, through the sensor, the moving amount of the film pressing roller 2 swinging up and down according to the height of the ground can be detected and fed back to the main machine head, and then the operator controls the telescopic oil cylinder through the control handle according to the information provided by the sensor to control the film-covering direct seeding machine to move up and down accordingly, so that the height difference between the mounting frame and the ground is always kept consistent, thereby ensuring the seeding depth during direct seeding.

[0051] For rainy, wet and soft clay fields (such as paddy fields), the film pressing roller 2 adopts an elliptical sphere 202. The elliptical sphere 202 has a lower density and has a certain buoyancy in the paddy field, always keeping the central axis 201 above the ground. At the same time, the ground height information is transmitted to the main machine head control system through the sensor to control the height, avoiding the phenomenon of mud pushing caused by getting stuck in the softer mud ground. When direct seeding in paddy fields, the disk shovels 14 adopt film pressing shovels, and the film edges on both sides of the film can be pressed into the soil through the film pressing shovels to fix the film and make the film have a certain tension, so as to facilitate the seeder to sow seeds.

[0052] For dry land, when sowing on the relatively hard dry land ground, the film pressing roller 2 is replaced so that the film pressing roller 2 has a certain pressure on the ground to ensure the adhesion of the film to the ground and prepare for the seeding of the subsequent seeding tooling. The disk shovels 14 adopt soil covering shovels, and the soil covering shovels can shovel soil to the film edge to press the film tightly, so as to facilitate the seeder to sow seeds.

[0053] Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 is that:

[0055] Please refer to the appendix with emphasis Figure 11 , a film cutting mechanism is provided on one side of the film laying tooling. The film cutting mechanism includes a film cutting knife 18 located on the side of the film pressing roller 2 facing away from the film cylinder 1, a connecting plate 19 fixedly connected to the mounting seat plate 3, a fourth swing arm rod 20 rotatably connected to the connecting plate 19, and a control cable connected to the main engine head. The film cutting knife 18 is arranged parallel to the film cylinder 1. A second spring 5 is arranged obliquely between the fourth swing arm rod 20 and the connecting plate 19. One end of the control cable is connected to a control lever installed on the machine head, and the other end is connected to a lug hole at the end of the fourth swing arm rod 20. When the main engine head reaches the field head and needs to turn, first cut the film with the film cutting mechanism, then lift the film covering and direct seeding machine to turn around. After turning, place the film covering and direct seeding machine on the ground and continue seeding. The specific operation is as follows: Pull the control lever, pull the control cable, drive the fourth swing arm rod 20, and the fourth swing arm rod 20 drives the film cutting knife to swing around the hinged end of the fourth swing arm rod 20 to a certain depth into the soil to cut the film laid on the ground. The elastic force of the second spring 5 enables the film cutting knife 18 to reset in time and keep a sufficient distance from the film when not in use to avoid accidentally cutting the film.

[0056] Please refer to the appendix with emphasis Figure 7 , a film supporting tooth plate 9 extending toward the side where the film pressing roller 2 is located is equidistantly installed along the length direction of the bottom of the film cylinder 1. The film supporting tooth plate 9 is located below the film pressing roller 2, and the elliptical sphere 202 is located in the gap between every two adjacent film supporting tooth plates 9. During use, the film extending from the film cylinder 1 passes between the upper side of the film supporting tooth plate 9 and the lower side of the film pressing roller 2. When the main engine head lifts the film covering and direct seeding machine, the film supporting tooth plate 9 will lift the film to avoid the film being scattered and affecting the film laying.

[0057] Others are the same as in Embodiment 1.

[0058] Embodiment 3

[0059] The difference between this embodiment and Embodiment 2 is that:

The second swing arm member 8 includes two long rods clamped on the two end faces of the seeder 6. The middle parts and the ends far from the seeder 6 of these two long rods are fixedly connected together by short rods, and the short rod at the end of the long rod is connected to the connecting sleeve 81. During use, by replacing the connecting sleeves 81 with different lengths, the spacing between the seeders 6 can be adjusted, so as to achieve the effect of adjusting the seeding row spacing according to requirements.

[0061] Please refer to the appendix with emphasis Figure 8, the seeder 6 includes a hollow wheel type feeder 61 and duckbill-shaped seeding openings 62 equally spaced on the circumferential surface of the hollow wheel type feeder 61. The seeder 6 has multiple specifications, and different numbers of duckbill-shaped seeding openings 62 are provided on the seeders 6 of different specifications. The two end faces of the hollow wheel type feeder 61 are detachably connected to the second swing arm member 8. The duckbill-shaped seeding openings 62 can pierce and punch holes in the film, open up and spit out seeds from the inside into the punched film holes, and then close for the next hole punching and seeding. By replacing the seeder 6 with different specifications according to requirements, the plant spacing of seeding can be adjusted.

[0062] Others are the same as in Embodiment 2.
