Description

Technical Field

[0001] The utility model relates to the technical field of rice transplanters, in particular to a rice transplanter with uniform plant spacing distribution. Background Art

[0002] A rice transplanter is an agricultural machinery equipment used for rice field operations. It is mainly used to insert rice seedlings into the soil of the rice field. Traditional rice transplanting operations require a lot of manpower and time, and the emergence of rice transplanters can significantly improve the efficiency and accuracy of transplanting operations.

[0003] Since the power transmission mechanism of many rice transplanters cannot realize the interactive coordination between the forward speed of the rice transplanter and the movement of the rice transplanting device, the spacing between the rice transplanters is often uneven.

[0004] In the prior art, a Chinese patent for a rice transplanter with uniform plant spacing (publication number CN201957432U) is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a bottom plate is provided, the front end of the bottom plate is slightly tilted upward, a bracket is connected to the bottom plate, and the rice transplanter and the rice seedling tray of the rice transplanter are fixed on the bracket; the rice transplanter is also provided with a power transmission device for driving the rice transplanter to move, the power transmission device includes at least one impeller in contact with the ground and a first sprocket coaxially fixed with the impeller and a second sprocket connected to the power output end of the power transmission device, and a chain is provided between the first sprocket and the second sprocket, so that the rice transplanter walking speed and the rice transplanter movement frequency are interactively realized, so that the plant spacing of the transplanted seedlings is relatively uniform. However, under this transmission mode, the rice transplanting process is completely linked with the moving process, so when moving on flat ground or when rice transplanting is not required, the rice transplanter will still move with the movement, so it will not only affect the life of the equipment, but also make the moving process of the rice transplanter require additional effort, which is not flexible enough and is not conducive to practical application. Summary of the invention

[0005] The utility model aims to provide a rice transplanter with uniform plant spacing distribution to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A rice transplanter with uniform plant spacing comprises a main body; support columns are symmetrically fixedly connected to the top of the main body, a mounting plate is fixedly connected between the adjacent sides of the two support columns, a rice transplanting assembly is arranged between the adjacent sides of the two support columns, the rice transplanting assembly is used to insert the rice seedlings into the soil, two wheel axles are rotatably connected between the two sides of the main body, rollers are fixedly connected at both ends of the wheel axles, side plates are also symmetrically fixedly connected to the top of the main body, a transmission assembly is arranged between the two side plates, the transmission assembly is used to realize power transmission between the wheel axles and the rice transplanting assembly so that movement and rice transplanting actions are synchronized, and a through groove is provided at the bottom of the main body.

[0008] By adopting the above technical solution, two push-pull movement modes are set corresponding to the movement of only the main body and the transplanting process. When only the main body needs to be moved, the handle acts as a push rod, and the main body is moved by pushing the handle, so that the rotation direction of the roller and the wheel shaft is opposite to the transplanting process. Therefore, the one-way bearing will not transmit, so that the first pulley, that is, the subsequent transplanting assembly, will not move, and then no transmission and transplanting operations will be performed during the moving process, avoiding the problem of reduced device life due to complete transmission of movement and transplanting.

[0009] A further improvement of the technical solution of the utility model is that the rice transplanting assembly includes a first rotating rod rotatably connected to one side of the mounting plate, a cam is fixedly connected to the outer side of the first rotating rod, a fixing plate is fixedly connected between the sides of the two supporting columns that are close to each other, a plurality of sliding rods are equidistantly slidably connected to the top of the fixing plate, a pressure plate is fixedly connected between the tops of the sliding rods, the bottoms of the sliding rods extend to the bottom of the fixing plate and are fixedly connected to a movable plate, a second spring is sleeved on the outer side of the sliding rod and located above the fixing plate, the bottom of the movable plate is fixedly connected to an insertion rod, and the bottom of the insertion rod extends to the bottom of the main body through a through groove and is provided with a notch.

[0010] By adopting the above technical solution, the cam is rotated and the second springs are cooperated to make the pressure plate perform upper limit reciprocating motion, and the movable plate is driven to reciprocate up and down through the sliding rod, and the insertion rod is driven to reciprocate up and down. When the insertion rod moves upward to be above the discharge port, the seedlings will continue to move downward until the roots are located below the insertion rod. As the insertion rod moves downward, the roots press downward through the notch to insert the seedlings into the rice field. Repeating the operation completes the transplanting of rice in the rice field.

[0011] A further improvement of the technical solution of the utility model is that: movable grooves are symmetrically provided on both sides of the inner wall of the main body, a limiting rod is fixedly connected between the two sides of the inner wall of the movable groove, a slider is slidably connected between the outer side of the limiting rod and the inner wall of the movable groove, a third rotating rod is rotatably connected to the side where the two sliders are close to each other, a first spring is sleeved on the outer side of the limiting rod, a material holding rack is hinged between the inner walls of the main body, the bottom of the material holding rack extends to the bottom of the main body through a through groove and is provided with multiple discharge ports, and the material holding rack and the third rotating rod are hinged by a connecting piece.

[0012] By adopting the above technical solution, during the rice transplanting process, the material rack continues to shake. The shaking caused by the vibration of the main body and the reduction of gravity in the material rack causes the third rotating rod to act on the slider to varying degrees. Cooperating with the first spring, the slider swings back and forth in the movable groove, causing the material rack to swing and assist in discharging.

[0013] A further improvement of the technical solution of the utility model is that: the transmission assembly includes a first bevel gear fixedly connected to one end of the first rotating rod, a second rotating rod is rotatably connected between the sides of the two side plates that are close to each other, a second bevel gear is fixedly connected to the outer side of the second rotating rod, the second bevel gear is meshingly connected to the first bevel gear, grooves are symmetrically opened at the bottom of the inner side of the main body, a first pulley is arranged on the outer side of one wheel axle and located inside the groove, two second pulleys are symmetrically fixedly connected to the outer side of the second rotating rod, the first pulley and the second pulley are connected by belt transmission, and a protective shell is fixedly connected to the bottom of the main body and located below the groove.

[0014] By adopting the above technical solution, the main body is moved by pulling, and the roller flips during the movement, driving the wheel shaft to rotate, thereby causing the first pulley to rotate, driving the second pulley to rotate, causing the second rotating rod to rotate, and the second bevel gear rotates accordingly, and drives the first bevel gear to rotate through meshing, thereby causing the first rotating rod to rotate.

[0015] A further improvement of the technical solution of the utility model is that the first pulley is connected to the wheel shaft via a one-way bearing.

[0016] By adopting the above technical solution, there is only one-way transmission between the wheel shaft and the first pulley. When transplanting is required, the transmission is performed along with the movement of the main body so that the transplanting action is performed; while no transmission is performed during the movement.

[0017] A further improvement of the technical solution of the utility model is that tooth patterns are arranged on the outer side of the roller.

[0018] By adopting the above technical solution, the friction between the wheels and the soil can be increased, thereby providing sufficient traction to ensure that the rice transplanter can smoothly travel in the rice field and complete the rice transplanting operation.

[0019] A further improvement of the technical solution of the utility model is that a handle is rotatably connected between the two side panels on the adjacent sides via a damping shaft, the handle is configured as an inner and outer rod-shaped structure that are slidably connected to each other, a plurality of screw holes are equidistantly provided on one side of the handle located on the inner rod, and the inner and outer rods of the handle are connected by screws.

[0020] By adopting the above technical solution, the angle of the handle can be flexibly controlled, and the handle can be controlled to be extended or shortened, so as to facilitate pushing or pulling operations.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a rice transplanter with uniform plant spacing. By setting two moving modes of push and pull corresponding to the movement of only the main body and the transplanting process, when only the main body needs to be moved, the handle acts as a push rod, and the main body moves by pushing the handle, so that the rotation direction of the roller and the wheel shaft is opposite to the transplanting process, so the one-way bearing will not be transmitted, so that the first pulley, that is, the subsequent transplanting assembly, will not move, and then the transmission and transplanting operation will not be performed during the moving process, avoiding the problem that the movement and transplanting are fully transmitted, resulting in a reduction in the life of the device and inconvenience in operation, which is conducive to practical application.

[0023] 2. The utility model provides a rice transplanter with uniform plant spacing distribution. By setting a transmission component, when transplanting rice seedlings, it is only necessary to pull the main body to move. During the movement, the roller flips, driving the wheel shaft to rotate, thereby causing the first pulley to rotate, driving the second pulley to rotate, causing the second rotating rod to rotate, and the second bevel gear to rotate accordingly, and driving the first bevel gear to rotate through meshing, thereby causing the first rotating rod to rotate, the cam to rotate, and cooperating with each second spring to make the pressure plate perform upper limit reciprocating motion, and drive the movable plate to reciprocate up and down through the sliding rod, and drive the insertion rod to reciprocate up and down. When the insertion rod moves upward to above the discharge port, the seedlings will continue to move downward until the roots are located below the insertion rod. As the insertion rod moves downward, the roots press downward through the notch to insert the seedlings into the rice field. Repeating the operation completes the transplanting of rice in the rice field. Uniform transplanting can be achieved without the need for additional power drive, which greatly reduces the implementation cost.

[0024] 3. The utility model provides a rice transplanter with uniform plant spacing. A material receiving frame is hinged on the main body and supported by an elastic structure. During the rice transplanting process, the material receiving frame continues to shake. The shaking is caused by the vibration of the main body and the reduction of gravity in the material receiving frame, which causes the third rotating rod to act on the slider to different degrees. The first spring cooperates with the slider to swing back and forth in the movable groove, causing the material receiving frame to swing, thereby assisting in discharging the material and avoiding material jamming.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the embodiments:

[0033] Example 1

[0034] like Figure 1 and Figure 2 As shown, the utility model provides a rice transplanter with uniform plant spacing, comprising a main body 1; support columns 3 are symmetrically fixedly connected to the top of the main body 1, a mounting plate 4 is fixedly connected between the sides of the two support columns 3 that are close to each other, a rice transplanting assembly is arranged between the sides of the two support columns 3 that are close to each other, and the rice transplanting assembly is used to insert the rice seedlings into the soil, two wheel axles 10 are rotatably connected between the two sides of the main body 1, rollers 9 are fixedly connected at both ends of the wheel axles 10, side plates 8 are also symmetrically fixedly connected to the top of the main body 1, a transmission assembly is arranged between the two side plates 8, and the transmission assembly is used to realize power transmission between the wheel axles 10 and the rice transplanting assembly so that the movement is synchronized with the rice transplanting action, and a through groove 20 is provided at the bottom of the main body 1.

[0035] In this embodiment, two push-pull movement modes are set corresponding to the movement of only the main body 1 and the transplanting process. When only the main body 1 needs to be moved, the handle acts as a push rod. By pushing the handle, the main body 1 moves, so that the rotation direction of the roller 9 and the wheel shaft 10 is opposite to the transplanting process. Therefore, the one-way bearing will not transmit, so that the first pulley 12, that is, the subsequent transplanting assembly, will not move, and then the transmission and transplanting operations will not be performed during the moving process, avoiding the problem that the life of the device is reduced due to the complete transmission of the movement and transplanting, and the inconvenience of operation, which is conducive to practical application.

[0036] Example 2

[0037] like Figure 2 and Figure 3As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the rice transplanting assembly includes a first rotating rod 5 rotatably connected to one side of the mounting plate 4, a cam 6 is fixedly connected to the outer side of the first rotating rod 5, a fixed plate 16 is fixedly connected between the sides of the two support columns 3 that are close to each other, a plurality of sliding rods 17 are equidistantly slidably connected to the top of the fixed plate 16, a pressure plate 18 is fixedly connected between the tops of the sliding rods 17, the bottoms of the sliding rods 17 extend to the bottom of the fixed plate 16 and are fixedly connected to a movable plate 21, a second spring 19 is sleeved on the outer side of the sliding rod 17 and located above the fixed plate 16, an insertion rod 22 is fixedly connected to the bottom of the movable plate 21, and the bottom of the insertion rod 22 extends to the bottom of the main body 1 through a through groove 20 and is provided with a notch 23.

[0038] In this embodiment, by rotating the cam 6, the pressure plate 18 is made to reciprocate up and down in cooperation with each second spring 19, and the movable plate 21 is driven to reciprocate up and down through the slide rod 17, and the insertion rod 22 is driven to reciprocate up and down. When the insertion rod 22 moves upward to be above the discharge port, the seedlings will continue to move downward until the roots are located below the insertion rod 22. As the insertion rod 22 moves downward, the roots are pressed downward through the notch 23 to insert the seedlings into the rice field. Repeating the operation completes the transplanting of rice in the rice field.

[0039] Example 3

[0040] like Figure 1 and Figure 4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, movable grooves 25 are symmetrically opened on both sides of the inner wall of the main body 1, and a limiting rod 26 is fixedly connected between the two sides of the inner wall of the movable groove 25, and a slider 27 is slidably connected between the outer side of the limiting rod 26 and the inner wall of the movable groove 25, and a third rotating rod 28 is rotatably connected to the side where the two sliders 27 are close to each other, and a first spring 2 is sleeved on the outer side of the limiting rod 26, and a material holding rack 29 is hinged between the inner walls of the main body 1, and the bottom of the material holding rack 29 extends to the bottom of the main body 1 through the through groove 20 and is opened with multiple discharge ports, and the material holding rack 29 and the third rotating rod 28 are hinged by a connecting piece.

[0041] In this embodiment, during the transplanting process, the material rack 29 continues to shake. The shaking caused by the vibration of the main body 1 and the reduction of gravity in the material rack 29 causes the third rotating rod 28 to act on the slider 27 to varying degrees. In conjunction with the first spring 2, the slider 27 swings back and forth in the movable groove 25, causing the material rack 29 to swing, thereby assisting in discharging.

[0042] Example 4

[0043] like Figure 1 and Figure 5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the transmission assembly includes a first bevel gear 7 fixedly connected to one end of the first rotating rod 5, a second rotating rod 13 is rotatably connected between the sides of the two side plates 8 that are close to each other, a second bevel gear 15 is fixedly connected to the outer side of the second rotating rod 13, the second bevel gear 15 is meshingly connected to the first bevel gear 7, and grooves 11 are symmetrically provided at the bottom of the inner side of the main body 1, a first pulley 12 is provided on the outer side of one of the wheel axles 10 and located inside the groove 11, two second pulleys 14 are symmetrically fixedly connected to the outer side of the second rotating rod 13, the first pulley 12 and the second pulley 14 are connected by belt drive, and a protective shell 24 is fixedly connected to the bottom of the main body 1 and located below the groove 11.

[0044] In this embodiment, the main body 1 is moved by pulling, and the roller 9 flips during the movement, driving the wheel shaft 10 to rotate, thereby causing the first pulley 12 to rotate, driving the second pulley 14 to rotate, causing the second rotating rod 13 to rotate, and the second bevel gear 15 to rotate accordingly, and driving the first bevel gear 7 to rotate through meshing, thereby causing the first rotating rod 5 to rotate.

[0045] Preferably, the first pulley 12 is connected to the wheel axle 10 via a one-way bearing.

[0046] In this embodiment, the wheel shaft 10 and the first pulley 12 are only transmitted in one direction. When transplanting is required, the transmission is performed along with the movement of the main body 1 so as to perform the transplanting action; while no transmission is performed during the movement.

[0047] like Figure 1 and Figure 2 As shown, preferably, the outer side of the roller 9 is provided with teeth.

[0048] In this embodiment, the friction between the wheels and the soil can be increased, thereby providing sufficient traction to ensure that the rice transplanter can smoothly travel in the rice field and complete the rice transplanting operation.

[0049] Example 5

[0050] like Figure 1 and Figure 2 As shown, based on Example 1, the utility model provides a technical solution: preferably, a handle is rotatably connected between the two side panels 8 on the adjacent sides via a damping shaft, and the handle is configured as an inner and outer rod-shaped structure that are slidably connected to each other. The handle is located on one side of the inner rod and has multiple screw holes equidistantly provided thereon, and the inner and outer rods of the handle are connected by screws.

[0051] In this embodiment, the angle of the handle can be flexibly controlled, and the handle can be controlled to be extended or shortened, so as to facilitate pushing or pulling operations.

[0052] The following is a detailed description of the working principle of the rice transplanter with uniform plant spacing.

[0053] like Figure 1-5 As shown, when transplanting is needed (the handle acts as a pull rod), the seedlings are placed in the material rack 29, and the roots of the seedlings at the bottom extend from the discharge port. When transplanting, the handle is controlled to rotate to Figure 2 The state shown in the figure is shown, and the handle is appropriately extended. At this time, the main body 1 can be pulled to move. During the movement, the roller 9 flips over, driving the wheel shaft 10 to rotate, thereby causing the first pulley 12 to rotate, driving the second pulley 14 to rotate, causing the second rotating rod 13 to rotate, and the second bevel gear 15 to rotate accordingly, and driving the first bevel gear 7 to rotate through meshing, thereby causing the first rotating rod 5 and the cam 6 to rotate, and cooperating with each second spring 19 to make the pressing plate 18 reciprocate up and down, and driving the movable plate 21 to reciprocate up and down through the sliding rod 17, and driving the insertion rod 22 to move up and down. When the rod 22 moves upward to the position above the discharge port, the seedlings will continue to move downward until the roots are located below the rod 22. As the rod 22 moves downward, the roots are pressed downward through the notch 23 to insert the seedlings into the rice field. Repeating the operation completes the transplanting of rice in the rice field. During the transplanting process, the material rack 29 continues to shake. The shaking is caused by the vibration of the main body 1 and the reduction of gravity in the material rack 29, so that the third rotating rod 28 acts on the slider 27 to varying degrees, and cooperates with the first spring 2 to make the slider 27 reciprocate in the movable groove 25, so that the material rack 29 swings to assist in discharging.

[0054] When only the main body 1 needs to be moved (the handle acts as a push rod), the main body 1 moves by pushing the handle, so that the rotation direction of the roller 9 and the wheel shaft 10 is opposite to the transplanting process, so the one-way bearing will not transmit, so that the first pulley 12, i.e. the subsequent transplanting assembly, will not move, and then no transmission and transplanting operations will be performed during the moving process, thereby avoiding the problem of reduced device life due to complete transmission of movement and transplanting, and inconvenient operation, which is beneficial to practical applications.

[0055] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
