Description

Technical Field

[0001] The present invention relates to the technical field of rice transplanters, and more specifically, to a rice transplanter and an integrated film-covering floating plate device. Background Art

[0002] A rice transplanter is an agricultural machine that plants rice seedlings in rice fields. Some existing rice transplanters are equipped with a film covering device to reduce water evaporation, inhibit weed growth, protect soil structure, and improve soil nutrient utilization by covering the ground with film during operation. At the same time, it reduces the pollution of agricultural production to the environment, promotes the healthy growth of rice, and increases yield.

[0003] For example, a Chinese patent document (Announcement No.: CN 207167028 U) provides a rice film covering transplanter that can cover with paper film, wherein a pressure wheel bracket is installed on the side bracket box, a pressure wheel is installed on the pressure wheel bracket, a paper film roller bracket is installed on the cross bracket box, a paper film roller is installed on the paper film roller bracket, a floating plate bracket is installed below the gearbox and the side bracket box, a floating plate is installed at the lower end of the floating plate bracket, a film covering roller bracket is installed on the floating plate bracket, a film covering roller is installed on the film covering roller bracket, and the film covering roller is located behind the floating plate and in front of the planting arm. The rice transplanter can simultaneously complete the two tasks of transplanting and paper film covering when transplanting rice.

[0004] Compared with the separate design of the floating plate device and the film covering device in the related art, the film covering roller bracket in the above patent is directly installed on the floating plate bracket, so that the bottom space of the rice transplanter is further simplified.

[0005] However, the film discharging roller in the above-mentioned film coating device often faces the problem of mud splashing interference, resulting in the film discharging being not smooth. In the long run, the film discharging roller is prone to rust and become brittle, and the floating plate device and the film coating device are prone to interfere with each other in some cases.

[0006] For the above problems, the related technologies do not provide effective solutions. Summary of the invention

[0008] Furthermore, the flexible baffle is made of transparent material.

[0009] Furthermore, the mounting cover and the rigid floating plate are respectively provided with a slot, and a portion of the flexible baffle is detachably inserted into the slot; the flexible baffle is mounted to the slot via a threaded fastener.

[0010] Furthermore, it comprises two non-overlapping flexible baffles, and the feedback component is arranged between the two flexible baffles.

[0011] Furthermore, one of the flexible baffles is formed with an avoidance gap to avoid the transmission axis of the implanting part.

[0012] Furthermore, a plurality of water-guiding edges are formed on the bottom surface of the rigid floating plate. The water-guiding edges are arc-shaped and extend along the longitudinal direction of the rigid floating plate. All the water-guiding edges are parallel to each other.

[0013] Furthermore, the height of the water-guiding edge is 5 mm to 15 mm, and the width of the water-guiding edge is 1.5 mm to 3 mm.

[0014] Furthermore, two sides of the rigid floating plate are rotatably connected to the mounting cover via connecting rods, and at least a portion of the connecting rods is arc-shaped and fits the mounting cover.

[0015] Furthermore, the connecting rod includes a first connecting part and a second connecting part, the first connecting part is in contact with the mounting cover; the second connecting part extends to the lower side of the film outlet roller, the second connecting part includes a connecting plate, the connecting plate is formed with a plurality of connecting holes, and the rigid floating plate is hinged to one of the connecting holes in the connecting plate near the side of the film pressing roller.

[0016] To achieve the above-mentioned purpose, the present application also provides a rice transplanter, including a planting part, a hydraulic solenoid valve and the integrated coating floating plate device in the above-mentioned scheme, the hydraulic pressure is connected to the planting part to control the lifting and lowering of the planting part; the mounting cover is fixed to the planting part; the coating mechanism also includes a coating roller, and the coating roller is installed to the outside of the mounting cover.

[0017] Furthermore, the feedback component includes a cable, the movably connected to the mounting cover, one end of the cable connected to the rigid float plate, and the other end of the cable connected to the tension sensor. When the rigid float plate rotates, the cable can be pulled, so that the tension sensor feeds back the signal to the hydraulic solenoid valve, and the implantation part drives the integrated coated float plate device to rise and fall.

[0018] Furthermore, the feedback component also includes a guide member and a limit member; the pull cable specifically includes a pull wire and a pull sleeve; the pull wire is located inside the pull sleeve, and the pull wire can slide relative to the pull sleeve; one end of the pull wire is connected to the guide wire, and the other end is fixedly connected to the tension sensor; the guide member is rotatably connected to the rigid floating plate near the end, and the middle part of the guide member is movably connected to the mounting cover, the limit member is fixedly installed to the frame, and the two ends of the pull sleeve are located between the limit member and the guide member; when the rigid floating plate rotates, it can drive the guide plate to move, so that the guide member and the limit member cooperate to squeeze the pull sleeve, causing the pull sleeve to deform and thereby pull the pull wire, so that the pull wire transmits the force to the tension sensor.

[0019] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0020] (1) The coating mechanism and the floating plate mechanism of the present application are highly integrated, which simplifies the structure of the rice transplanter. The floating plate mechanism can effectively protect the film-discharging roller while realizing the profiling function. Specifically, the rigid floating plate and the transparent flexible baffle in the floating plate mechanism block the mud from the film-discharging roller, reducing the impact of mud splashed by the wheels on both sides of the rice transplanter on the film-discharging roller and extending the service life of the film-discharging roller. At the same time, the flexible baffle is soft and easy to deform, and can fully cooperate with the work of the rigid floating plate. In the process of blocking mud, it will not interfere with the movement of the rigid floating plate;

[0021] (2) The flexible baffle is made of transparent material. This design allows the user to directly observe the working condition of the ground film roll in the film delivery roller through the flexible baffle. If there is only a small amount of ground film roll remaining or missing in the film delivery roller, the user can replace or replenish the ground film roll in time;

[0022] (3) The bottom surface of the rigid floating plate is formed with a plurality of water-guiding edges, which are arc-shaped and extend in the longitudinal direction of the rigid floating plate, and all the water-guiding edges are parallel to each other. The longitudinal direction of the rigid floating plate is perpendicular to the axis of the film-discharging roller. Therefore, after the wheels of the rice transplanter splash muddy water onto the flexible baffle, the muddy water flows to the rigid floating plate and can flow back into the field along the water-guiding edges, and is not easy to adhere to the surface of the floating plate mechanism. On the other hand, the water-guiding edges can also increase the strength of the rigid floating plate to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0041] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0042] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are mainly intended to better describe the present application and its embodiments, and are not intended to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation. Moreover, in addition to being used to indicate orientation or positional relationships, some of the above terms may also be used to express other meanings. For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific circumstances.

[0043] The present application provides an integrated film-coated floating plate device, such as Figure 1 As shown, it includes a laminating mechanism 100 and a floating plate mechanism 200 .

[0044] like Figure 1 , Figure 2As shown, the laminating mechanism 100 includes a mounting cover 110 and a film discharging roller 120. The mounting cover 110 is semi-cylindrical and is used to be mounted on the implanting part; the film discharging roller 120 is mounted on the inner side of the mounting cover 110. The mounting cover 110 body can play a certain protective role on the film discharging roller 120.

[0045] As some alternative solutions, the mounting cover 110 may also be square or the like.

[0046] Specifically, if Figure 1 As shown, the film laminating mechanism 100 further includes a film pressing roller 130, which is mounted on the outside of the mounting cover 110. The film discharging roller 120 can be mounted with a ground film roll and output the ground film toward the bottom of the film pressing roller 130, and the film pressing roller 130 is used to stick the ground film to the field to prevent the ground film from not sticking to the field.

[0047] As an optional solution, the film discharging roller 120 can be connected to other mechanical components to produce film; as another optional solution, the film discharging roller 120 may not be connected to other mechanical components. Before use, the user pulls the ground film from the film discharging roller 120 to the bottom of the film pressing roller 130, and uses the friction of the field surface and the tension of the water to produce the film.

[0048] like Figure 1 , Figure 3 , Figure 4 As shown, the floating plate mechanism 200 is connected to the mounting cover 110. The floating plate mechanism 200 includes a rigid floating plate 210, a feedback assembly 220 and a flexible baffle 230.

[0049] In detail, the rigid float 210 cooperates with the feedback component 220 to be equivalent to the function of the floating boat in the prior art. When the rigid float 210 encounters a slope or a pit, it will rotate, such as warping up, and the feedback component 220 will be linked. The planting part of the rice transplanter will rise and fall through the feedback of the feedback component 220, and transplant rice seedlings along the curve of the ground (profiling), thereby ensuring that the planting depth remains consistent, thereby ensuring the survival rate and yield of the seedlings.

[0050] As an optional solution, the structure of the feedback component 220 in this embodiment can be a connecting rod group or an electronically controlled horizontal sensor or other structural forms, and can also refer to the feedback component or other prior art in the Chinese patent document with application number 2023115797576, etc. This embodiment is not specifically limited here.

[0051] like Figure 3 , 4As shown, the rigid floating plate 210 is an arc-shaped plate, which is rotatably connected to the lower side of the mounting cover 110, and the rigid floating plate 210 surrounds a partial area of ​​the circumference of the film-discharging roller 120, thereby covering a partial area of ​​the lower half of the film-discharging roller 120. The feedback component 220 is connected to the rigid floating plate 210. Specifically, the feedback component 220 is located on the front side of the mounting cover 110, and the rear side of the mounting cover 110 is used for film discharging. The flexible baffle 230 is connected to the mounting cover 110 on one side and to the rigid floating plate 210 on the other side, and the flexible baffle 230 surrounds a partial area of ​​the circumference of the film-discharging roller 120. When the rigid floating plate 210 rotates, the flexible baffle 230 can be twisted or unfolded.

[0052] Specifically, when the rigid floating plate 210 encounters a raised earth slope, it rotates under the push of the earth slope, and twists the flexible baffle 230 at the same time; after the rigid floating plate 210 passes the earth slope, it returns to its original position, and when the force twisting the flexible baffle 230 decreases, the flexible baffle 230 unfolds. In this process, the flexible baffle 230 can always protect the film-exiting roller 120.

[0053] In this way, the coating mechanism 100 and the floating plate mechanism 200 in this embodiment are highly integrated, so that the structure of the rice transplanter is simplified. The floating plate mechanism 100 can effectively protect the film discharge roller 120 while realizing the profiling function. Specifically, the rigid floating plate 210 and the transparent flexible baffle 230 of the floating plate mechanism 200 are combined to block mud for the film discharge roller 120, thereby reducing the impact of mud splashed by the wheels on both sides of the rice transplanter on the film discharge roller 120 and extending the service life of the film discharge roller 120. At the same time, the flexible baffle 230 is soft and easy to deform, and can fully cooperate with the work of the rigid floating plate 210. In the process of blocking mud, it will not interfere with the movement of the rigid floating plate 210.

[0054] Optional, such as Figure 2 As shown, the installation cover 110 may be a split structure, for example, composed of two semi-cylindrical components, each of which is provided with a hanging plate 111 for connecting with the implanting part.

[0055] Preferably, the flexible baffle 230 is made of a transparent material. It is worth emphasizing that the "transparent material" here can be a completely transparent or colored translucent material, such as PVC-F and other plastics. This design allows the user to directly observe the working condition of the ground film roll in the film delivery roller 120 through the flexible baffle 230. If there is only a small amount of ground film roll remaining or missing in the film delivery roller 120, the user can replace or replenish the ground film roll in time.

[0056] As an optional solution, both sides of the flexible baffle 230 are glued to the mounting cover 110 and the rigid floating plate 210 .

[0057] As another preferred solution, Figure 4As shown, the mounting cover 110 and the rigid floating plate 210 are respectively provided with a slot 231, and part of the flexible baffle 230 is detachably inserted into the slot 231. When the flexible baffle 230 is dirty or damaged, the flexible baffle 230 can be directly removed from the slot 231 of the mounting cover 110 and the rigid floating plate 210 to clean, maintain or replace the flexible baffle 230. Specifically, the flexible baffle 230 is mounted to the slot 231 by threaded fasteners, and both side walls of the slot 231 and the flexible baffle 230 are provided with openings, and the flexible baffle 230 is aligned with the opening of the slot 231, and bolts are inserted into the openings and the flexible baffle 230, and the bolts cooperate with nuts to press the slot 231, thereby clamping the flexible baffle 230.

[0058] Furthermore, the floating plate mechanism 200 in this embodiment includes two non-overlapping flexible baffles 230, and the feedback component 220 is disposed between the two flexible baffles 230, and the two flexible baffles 230 can avoid the feedback component 220. As an alternative, the flexible baffle 230 can also be only one piece, with a gap formed in the middle to provide installation space for the feedback component 220.

[0059] Furthermore, a flexible baffle 230 is formed with an avoidance gap to avoid the transmission shaft of the transplanting part, and the avoidance gap can adapt to some compact rice transplanter models.

[0060] It is worth mentioning that the “avoidance gap” of the above-mentioned flexible baffle 230 or the interval between the two flexible baffles 230 may cause a small amount of exposure of the film-discharging roller 120, but since the source of the mud and water is mainly the mud and water splashed by the wheels on both sides of the rice transplanter, the small amount of exposure in the middle of the film-discharging roller 120 has basically no effect on the overall protective performance of the flexible baffle 230.

[0061] Preferably, Figure 3 As shown, a plurality of water-guiding edges 211 are formed on the bottom surface of the rigid floating plate 210. The water-guiding edges 211 are arc-shaped and extend in the longitudinal direction of the rigid floating plate 210. All the water-guiding edges 211 are parallel to each other. The longitudinal direction of the rigid floating plate 210 is perpendicular to the axis of the film-discharging roller 120. Therefore, after the wheels of the rice transplanter splash muddy water onto the flexible baffle 230, the muddy water flows to the rigid floating plate 210 and can flow back into the field along the water-guiding edges 211. It is not easy to adhere to the surface of the floating plate mechanism 200. On the other hand, the water-guiding edges 211 can also increase the strength of the rigid floating plate 210 to a certain extent.

[0062] Furthermore, the height of the water-guiding edge 211 is 5 mm to 15 mm, such as 5 mm, 6 mm, 8 mm, 12 mm or 14 mm, and the width is 1.5 mm to 3 mm, such as 2 mm. In accordance with the width of the water-guiding edge 211, the water-guiding edge 211 cannot effectively guide water if its height is less than 5 mm, and it is easily broken by the soil slope if it is greater than 15 mm.

[0063] Specifically, both sides of the rigid floating plate 210 are rotatably connected to the mounting cover 110 through the connecting rods 240 . At least a portion of the connecting rods 240 is arc-shaped and fits the mounting cover 110 to enhance the strength of the connecting rods 240 .

[0064] More specifically, Figure 5 As shown, the connecting rod 240 includes a first connecting portion 241 and a second connecting portion 242, and the first connecting portion 241 is in contact with the mounting cover 110. The second connecting portion 242 extends to the lower side of the film discharge roller 120, and the second connecting portion 242 includes a connecting plate 2421, and the connecting plate 2421 is formed with a plurality of connecting holes 2421a. The side of the rigid floating plate 210 close to the film pressing roller 130 is hinged to one of the connecting holes 2421a in the connecting plate 2421. This design allows the relative position of the rigid floating plate 210 and the mounting cover 110 to be adjusted to a certain extent, and can adapt to different installation forms.

[0065] Further, such as Figure 3 , 5 As shown, matching plates 212 are provided on both sides of the rigid floating plate 210 , and the rigid floating plate 210 is hinged and fitted with the connecting plate 2421 through the matching plates 212 to increase the connection strength.

[0066] As a specific solution, the present embodiment also provides a rice transplanter, which includes a planting part, a hydraulic solenoid valve and the above-mentioned integrated film coating floating plate device, the hydraulic solenoid valve is connected to the planting part to control the lifting and lowering of the planting part; the mounting cover 110 is fixed to the planting part, in detail, the film pressing roller 130 and the film outlet roller 120 are both installed on the planting part, and rise or fall with the planting part.

[0067] Specifically, Figure 6 As shown, the feedback component 220 includes a cable 221, which is movably connected to the mounting cover 110 and can move relative to the mounting cover 110. One end of the cable 221 is connected to the rigid floating plate 210, and the other end of the cable 221 is connected to the tension sensor. When the rigid floating plate 210 rotates, it can pull the cable 221, so that the tension sensor feeds back the signal to the hydraulic solenoid valve, and the planting part drives the integrated film covering floating plate device to rise and fall, so that the planting part can carry the film outlet roller 120 and the film pressing roller 130 as a whole to complete the film covering with the rise and fall of the ground, so that the ground film is more closely fitted to the field.

[0068] More specifically, Figure 6As shown, the feedback assembly 220 also includes a guide member 222 and a stopper; the cable 221 specifically includes a pull wire 2211 and a pull sleeve 2212, the pull wire 2211 is located inside the pull sleeve 2212 and can slide relative to the pull sleeve 2212, one end of the pull wire 2211 is connected to the wire member, and the other end is fixedly connected to the tension sensor. The guide member 222 is rotatably connected to the rigid floating plate 210 near the end, and the middle part of the guide member 222 is movably connected to the mounting cover 110, the stopper is fixedly installed to the frame, and the two ends of the pull sleeve 2212 are located between the stopper and the guide member 222. When the rigid floating plate 210 rotates, it can drive the guide member 222 to move, so that the guide member 222 cooperates with the limit member to squeeze the pull sleeve 2212, causing the pull sleeve 2212 to deform and thereby pull the pull wire 2211, so that the pull wire 2211 transmits the force to the tension sensor. After the tension sensor detects the tension, it feeds back the signal to the controller. The controller controls the opening of the hydraulic solenoid valve, thereby shortening the hydraulic cylinder and raising the implanting part.

[0069] Specifically, the pull wire 2211 can be fixedly connected to the guide member 222, or can be movably connected to the guide member 222. If the pull wire 2211 is movably connected to the guide member 222, more buffer space is provided for the rise of the implanting part.

[0070] In this application, the terms "installed", "set", "provided with", "connected", "connected", and "socketed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0071] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

A rice transplanter according to claim 11, characterized in that: The feedback assembly further includes a guide member and a limit member; the cable specifically includes a pull wire and a pull sleeve; the pull wire is located inside the pull sleeve, and the pull wire can slide relative to the pull sleeve; one end of the pull wire is connected to the wire member, and the other end is fixedly connected to the tension sensor; The guide member is rotatably connected to the rigid floating plate at a position close to the end, and the middle part of the guide member is movably connected to the mounting cover, the limiter is fixedly mounted to the frame, and the two ends of the pull sleeve are located between the limiter and the guide member; When the rigid floating plate rotates, it can drive the guide plate to move, so that the guide member and the limit member cooperate to squeeze the pull sleeve, causing the pull sleeve to deform and thus pull the pull wire, so that the pull wire transmits the force to the tension sensor.
