Description
Technical Field
[0001] The utility model relates to the technical field of rice planting equipment, and specifically discloses an automatic rice transplanter with film mulching function. Background Art
[0002] The mechanized film mulching and rice transplanting technology can greatly improve the rice planting efficiency and save a large amount of labor and time costs. During the operation of the existing rice transplanter with film mulching function, it is driven straight along the paddy field by a tractor. During the driving process, the film roll is unrolled synchronously, and the film is pressed against the ground by a film pressing wheel. Then, the transplanter pierces the film and inserts the rice seedlings into the soil. Currently, the existing rice transplanter with film mulching function can complete the above actions. However, when the machine travels to the field for a U-turn operation, the driver needs to get off the tractor to manually cut the film. After cutting, the machine is turned around. After the U-turn is completed, the driver needs to get off again to press the end of the film into the soil for fixation. The whole operation process is time-consuming and laborious, and the degree of automation is relatively low.
[0003] The utility model patent with the application number 2018219084619 discloses a rice transplanter with film mulching function, which includes a vehicle body. Wheels are arranged below the chassis of the vehicle body. A suspension bracket is arranged at the rear side of the chassis. A seedling box and a film mulching roller group are connected to the suspension bracket. A rice transplanting mechanism is arranged below the seedling box. The film mulching roller group is located in front of the rice transplanting mechanism. The film mulching roller group includes a roller shaft. A long film pressing roller is sleeved on the roller shaft. Two short film pressing rollers are respectively sleeved on both sides of the long film pressing roller on the roller shaft. Both sides of the long film pressing roller and the short film pressing rollers are connected to the roller shaft through a bracket composed of an arm plate and a hinge sleeve to form the film mulching roller group. A film supporting frame is arranged at the rear side of the suspension bracket for the film mulching roller group. The rice transplanter with film mulching function disclosed in this patent can only complete the process of rice transplanting and film mulching, and still requires manual film cutting and manually pressing the end of the film into the soil for fixation during the U-turn process of the machine. In addition, there are some other deficiencies in this rice transplanter with film mulching function. For example, due to the action of the tractor wheels, the mud surface is uneven, and the film cannot be tightly pressed against the mud surface. Coupled with the fact that the two ends of the film are not pressed into the soil, the film is easily blown up by the wind and floated by the water. Another example is that in the existing rice transplanter, when facing a waterlogged plot, there is no hard object to support the film, resulting in the transplanter being unable to pierce the film and the rice seedlings being unable to take root in the soil. When the bottom of the field is uneven, the rice transplanting table sinks. As a result, the edges and corners of the rotary box catch the film and wrap the film around the box body, making it impossible to operate normally. Based on the above series of problems of the existing rice transplanter with film mulching function, this application proposes an automatic rice transplanter with film mulching function that can effectively solve the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problems that the existing rice transplanter with film mulching function cannot realize automatic operations of rice transplanting and film mulching, U-turn film cutting, and film pressing, as well as various problems proposed in the background art.
[0005] The utility model is realized by the following technical solutions:
[0006] An automatic rice transplanter with film mulching function, comprising a rice transplanter and a film mulching mechanism. The film mulching mechanism includes a film roll mounting part arranged below the rice transplanter and a rotating film cutting clamp assembly. The rotating film cutting clamp assembly includes a swing frame rotatably arranged. One end of the swing frame close to the film roll mounting part is connected with a lifting and lowering air cylinder, and the other end is provided with a film cutting saw-shaped clamp. And a clamping air cylinder for realizing the opening and closing of the lower clamping jaws of the film cutting saw-shaped clamp is connected to the film cutting saw-shaped clamp. A film roll braking air cylinder for pressing and fixing the film roll material is arranged on the film roll mounting part.
[0007] As a further setting of the above solution, the two clamping strips on both sides of the film cutting saw-shaped clamp are respectively strip-shaped and saw-tooth strip-shaped, and the upper ends of the strip-shaped and saw-tooth strip-shaped clamping strips are rotatably connected by a pin shaft and a torsion spring.
[0008] When the automatic rice transplanter with film mulching function disclosed by the utility model needs to turn around after the film mulching and rice transplanting are completed, the swing frame is driven by the lifting and lowering air cylinder to rotate, so that the end with the film cutting saw-shaped clamp is lowered. And during the lowering process of the film cutting saw-shaped clamp, the lower clamping jaws of the film cutting saw-shaped clamp are controlled by the clamping air cylinder to open until they contact the film on the ground. At the same time, the film roll braking air cylinder will extend to press and fix the film roll material to prevent it from continuing to unwind under the action of the film saw-shaped clamp. The film cutting saw-shaped clamps after the pointed jaws are opened act on the straightened film. On the one hand, the film is cut by the saw-tooth strip-shaped clamping strip, and on the other hand, the film end of the cut part can be clamped after the pointed jaws are closed.
[0009] After the film cutting saw-shaped clamp grabs the film, it is lifted together with the rice transplanter. When the machine turns around and then puts it down again, the falling inertia of the film cutting saw-shaped clamp is used to make the film cutting saw-shaped clamp plunge the grabbed film end into the soil for fixation. Then the clamping jaws of the film cutting saw-shaped clamp are opened by the clamping air cylinder. After the film is released, the entire rotating film cutting clamp assembly is lifted by the lifting and lowering air cylinder, and then the rice transplanter with film mulching function continues to move forward for operation.
[0010] As a further setting of the above solution, two parallel film tying wheels are arranged between the film roll mounting part and the film cutting saw-shaped clamp. The design of the above film tying wheels can plunge the two side ends of the film into the soil to a certain depth after the film covers the paddy field surface, preventing the subsequent film from being blown up by the wind or floating up by the water.
[0011] As a further setting of the above solution, a sensing and pressing roller is provided between the film winding wheel and the film roll mounting part, and the sensor on the sensing and pressing roller is electrically connected to the microcomputer on the tractor. The design of the above-mentioned sensing and pressing roller can, on the one hand, press the unwound film against the paddy field surface to ensure the film covering effect; on the other hand, it can also sense the ground height through the sensing and pressing roller and feedback it to the microcomputer on the tractor, and then the microcomputer can timely adjust the height distance between the rice transplanting table and the ground by controlling the hydraulic lifting device, accurately controlling the depth of the transplanter inserted into the soil, so that the depths of all transplanted seedlings are the same.
[0012] As a further setting of the above solution, a leveling harrow is installed below the side of the film roll mounting part close to the tractor. The design of the above-mentioned leveling harrow can use its own weight as pressure to level the uneven field surface and ruts, making the field surface flat when laying the film, and solving the problem that the depths of the seedlings are different after transplanting on the uneven field surface.
[0013] As a further setting of the above solution, a wheel mudguard is installed on the side of the film roll mounting part close to the tractor, and two front and rear side mudguards are provided below the wheel mudguard. The design of the above-mentioned wheel mudguard can effectively block the mud and water thrown out by the wheels, solving the problem of mud and water pouring into the leveling harrow and the film roll mounting part. At the same time, the side mudguards can block the thin mud within the width range of the leveling harrow, effectively preventing the thin mud pressed out by the leveling harrow from flowing to both sides and covering and destroying the adjacent rows of seedlings that have been planted.
[0014] As a further setting of the above solution, a film piercing knife is provided beside the transplanting needle on the transplanter of the rice transplanter. The design of the above-mentioned film piercing knife can effectively pierce the film, solving the problem that the film in the waterlogged land has no hard object to support the film, resulting in the transplanting needle in the transplanter being unable to effectively pierce the film.
[0015] As a further setting of the above solution, an anti-film-wrapping protection ring is provided on the outer circumferential surface of the rotary box on the rice transplanter. The design of the above-mentioned anti-film-wrapping protection ring can solve the problem that when the rice transplanter walks to the dark pit at the bottom of the field, the entire rice transplanter suddenly drops, resulting in the high-speed rotating rotary box falling into the soil, and the edges and corners of the rotating rotary box catch the film and wrap the film on the box body, making it impossible to operate normally.
[0016] As a further setting of the above solution, it further includes a tractor, and a film edge trimming and cutting device is provided at the front end of the tractor. The film edge trimming and cutting device includes a rotary lifting frame with a movable end that can be lifted and lowered. The movable end of the rotary lifting frame is provided with a ground-touching shaft roller, and a downward-facing cutting blade is provided at the end of the ground-touching shaft roller. The design of the above-mentioned film edge trimming and cutting device can effectively solve the problem that the remaining width is not enough in the last trip, and one side of the wheels of the tractor and the rice transplanter need to roll on the already laid film and pull and displace the already laid film, damaging the already planted seedlings.
[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0018] On the basis of realizing stable film covering and rice transplanting, the automatic rice transplanting and film covering machine disclosed by the present utility model also has the functions of automatically cutting the film before the machine turns around and automatically pressing and fixing the film after turning around. The whole process is automatically processed without manual assistance, effectively improving the efficiency of the whole rice transplanting and film covering process.
[0019] During the process of cutting and grasping the film by the rotary film cutting clamp assembly in the automatic rice transplanting and film covering machine, the film roll material is tightly pressed and fixed by the film roll braking cylinder, so that the film is in a straightened state during this process, effectively solving the problem that the existing film cutting mechanism cannot effectively cut the film because the film has no hard object support and the loose film is pressed into the soil.
[0020] Through the design of components such as the film tying wheel, the leveling harrow, and the sensing compaction roller, the automatic rice transplanting and film covering machine can make the film tightly adhere to the surface of the paddy field, which not only ensures the stability of the film after film covering, but also effectively solves the problem that the seedlings are of different depths after rice transplanting on an uneven paddy field surface.
[0021] The automatic rice transplanting and film covering machine is improved by the film piercing knife and the anti-film wrapping protection ring, which can effectively pierce the film, solve the problem that the film has no hard object support in the waterlogged land and the rice needles in the transplanter cannot effectively pierce the film, and at the same time can also solve the problem that the edges and corners of the flipped rotary box catch the film and wrap the film on the box body, making it impossible to operate normally.
[0022] Through the design of the wheel mudguard and the side mudguard, the automatic rice transplanting and film covering machine not only solves the problem of muddy water pouring into the leveling harrow and the film roll installation part, but also effectively blocks the problem that the thin mud pressed out by the leveling harrow flows to both sides and covers and destroys the adjacent row of seedlings that have been planted.

[0027] In order to enable those skilled in the art to better understand the solution of this application, the following will, in conjunction with the accompanying drawings in the embodiments of this application, clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of this application.
[0028] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the attached Figures 1 - 3 drawings and describe this application in detail in combination with the embodiments. Embodiment 1
[0029] Embodiment 1 discloses an automatic rice transplanting and film mulching machine. Referring to the attached Figure 1 drawings and the attached Figure 2 drawings, its main structure includes a rice transplanter 1 connected to a tractor and a film mulching mechanism 2. The rice transplanter 1 includes a seedling planting table 101 connected to the hydraulic lifting device at the rear of the tractor, and the film mulching mechanism 2 is arranged below the seedling planting table 101. At the lower end of the seedling planting table 101, there is a row of rice transplanting devices 102 and a rotary box 103. The specific structural designs of the rice transplanting devices 102 and the rotary box 103 are prior arts and will not be elaborated in this Embodiment 1.
[0030] In order to enable the rice transplanting device 102 to better break the film and then insert the grabbed rice seedlings into the field soil, in this Embodiment 1, a film breaking knife 104 is additionally installed beside the rice transplanting needles in the rice transplanting device 102, so that when the rice transplanting device 102 operates, the sharp film breaking knife first pokes a hole in the film, and then the rice transplanting device 102 sends the seedlings into the hole, so that each seedling is inserted into the soil, effectively solving the problem that in a waterlogged plot, the film has no hard object to support it, resulting in the rice transplanting needles in the rice transplanting device being unable to effectively pierce the film, and further avoiding the problem that the seedlings cannot take root when inserted on the film. In addition, in this Embodiment 1, an anti-film-wrapping protection ring 105 is also arranged on the outer circumferential surface of each rotary box 103, thus solving the problem that during film mulching and rice transplanting, due to the uneven bottom of the field, when the rice transplanter walks to a hidden pit at the bottom of the field, the entire rice transplanter suddenly drops, causing the high-speed rotating rotary box to fall into the soil, and the edges and corners of the rotating rotary box catch the film and wrap the film on the box body, making it impossible to operate normally.
[0031] The film covering mechanism 2 includes a film roll mounting part 201 and a rotary film cutting clamp assembly 202. The film roll mounting part 201 is installed below the rice transplanting table 101 and on the side close to the tractor, so that the film roll material can be installed in the film roll mounting part 201 for discharging. In addition, a film roll braking cylinder 203 is provided above the film roll mounting part 201. During the process of the rotary film cutting clamp assembly 202 cutting and grasping the film, the film roll braking cylinder 203 can automatically extend to press and fix the film roll material, preventing the film roll from rotating, so that the film between the film roll and the film cutting saw-type clamp assembly remains taut, solving the problem that the film between the film roll and the film cutting saw-type clamp assembly sags and droops during film cutting in the past, and the film roll unwinds the film disorderly under the dragging of the sagging film.
[0032] Refer to the attached Figure 2 and the attached Figure 3 As shown in the figure, the rotary film cutting clamp assembly 202 includes a swing frame 2021, a lifting and lowering cylinder 2022 and a film cutting saw-type clamp assembly. The swing frame 2021 is rotatably connected to the frame of the entire film covering machine through an intermediate pin shaft. Then, one end of the swing frame 2021 close to the tractor is connected to the lifting and lowering cylinder 2022, and the film cutting saw-type clamp assembly is arranged at the other end of the swing frame 2021 (i.e., the end far from the tractor). In addition, in order to ensure that both front and rear ends of the film can be inserted into the soil during the film covering process to prevent the film from being blown up by the wind or floated up by the water, in this Embodiment 1, two parallel film tying wheels 204 are further arranged between the film roll mounting part 201 and the film cutting saw-type clamp assembly. Through the action of the front and rear film tying wheels 204, both sides of the film can be effectively inserted into the soil to a certain depth.
[0033] The film-breaking saw-type clamp assembly includes a film-breaking saw-type clamp 2023 arranged at the end of the swing frame 2021. The clamping strips on both sides of the film-breaking saw-type clamp 2023 are respectively strip-shaped and saw-tooth strip-shaped, and the upper ends of the two are rotatably connected through a pin shaft and a torsion spring. A clamping force cylinder 2024 is also arranged at the end of the swing frame 2021 or on the film-breaking saw-type clamp 2023. Through the clamping force cylinder 2024, the opening and closing of the lower end of the film-breaking saw-type clamp 2023 can be actively realized. When the machine travels to the end of the paddy field and needs to turn around to switch the driving route, first start the lifting and lowering cylinder 2022 to realize the rotation of the swing frame 2021, so as to rotate and lower one end of the film-breaking saw-type clamp assembly. When the film-breaking saw-type clamp assembly rotates and lands, the clamping force cylinder 2024 controls the opening of its jaws. After piercing into the soil, the jaws are then closed, so that while tearing the film, the film is clamped. Then, after the film-breaking saw-type clamp 2023 grabs the film, it is lifted together with the rice transplanting table 101. When the machine turns around and rotates and falls again, the clamping plate in the film-breaking saw-type clamp 2023 pierces the film into the soil and fixes it through the falling inertia. At the same time as the clamping plate falls, the jaws open. After releasing the film, the entire rotating film-breaking clamp assembly 202 is lifted by the lifting and lowering cylinder 2022. Finally, the transplanter continues to move forward for operation. In this embodiment 1, all the actions of the rotating film-breaking clamp assembly 202 are completed by the microcomputer on the tractor controlling the cylinder actions, which can realize automatic film-breaking and automatic film-releasing, and the whole process does not require manual assistance and intervention. Embodiment 2
[0034] Embodiment 2 discloses an automated rice transplanter with film mulching, which is further optimized and improved based on the technical solution in Embodiment 1. The same parts as in Embodiment 1 will not be described again.
[0035] In this Embodiment 2, a sensing and pressing roller 205 is arranged between the film-piercing wheel 204 and the film roll mounting part 201. The sensing and pressing roller 205 is composed of a pressing roller and a sensor. The sensor is connected to the roller shaft of the pressing roller. While the pressing roller rolls on the ground to realize film pressing, it can also sense the ground height. Then the sensor feeds the ground height information back to the microcomputer on the tractor, and then the microcomputer timely adjusts the height distance between the rice transplanting table 101 and the ground by controlling the hydraulic lifting device, accurately controlling the depth of the rice transplanter 102 inserted into the soil, so that the depths of all transplanted seedlings are the same.
[0036] A leveling harrow 208 is installed below the film roll installation part 201 near the tractor side. The leveling harrow 208 is composed of semi-circular long steel plates, which rotates around the central axis at the front upper end and naturally droops. With its own weight as the pressure, it levels the uneven field surface and ruts, making the field surface flat when laying the film, and solving the problem that the seedlings are of different depths after transplanting in the uneven field surface. In addition, in this Embodiment 2, on the one hand, a wheel mudguard 206 is installed on the side of the film roll installation part 201 near the tractor, and on the other hand, two front and rear side mudguards 207 are arranged below the wheel mudguard 206. The design of the wheel mudguard 206 can effectively block the muddy water thrown out by the wheels, solving the problem that the muddy water pours into the leveling harrow 208 and the film roll installation part 201; at the same time, the side mudguards 207 can block the thin mud within the width range of the leveling harrow 208, effectively preventing the thin mud pressed out by the leveling harrow 208 from flowing to both sides and covering and destroying the adjacent row seedlings that have been planted.
[0037] Finally, a trimming and film cutting device 3 is also arranged on the tractor in front of the transplanter 1. The trimming and film cutting device 3 includes a rotary lifting frame 301 rotatably connected to the tractor. An electric push rod 302 is also connected between the rotary lifting frame 301 and the tractor, so that the lifting of the movable end of the rotary lifting frame 301 is realized under the action of the electric push rod 302. A ground-touching shaft roller 303 is rotatably arranged at the movable end of the rotary lifting frame 301, and a trimming blade 304 facing downwards is arranged at the end of the ground-touching shaft roller 303. When the width of the field block during film covering and transplanting cannot exactly match the product of the film width and the number of passes, and when it is found that the remaining width of the last pass of the field block is less than the width of the film covered by the transplanter when the machine tool operates to the last pass of the field block, the movable end of the rotary lifting frame 301 can be pushed down by the electric push rod 302 at this time, so that the trimming blade 304 cuts off a part of the already laid film, so that the remaining width is exactly the same as the width of the transplanter. It effectively solves the problem that the remaining width of the last pass is not enough, and one side of the wheels of the tractor and the transplanter has to roll on the already laid film and pull and displace the already laid film to damage the already planted seedlings.
[0038] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
