Description

Technical Field

[0001] This invention belongs to the technical field of transplanting machinery, and relates to a rice transplanter for rice planting. Background Technology

[0002] Rice transplanting technology is a lightweight rice cultivation technique that has been applied and rapidly developed in my country in recent years. It has changed the traditional rice planting habits of bending over to pull seedlings and transplanting them that have been followed by farmers for thousands of years. It has advantages such as high yield, stable yield, labor saving, seed saving, seedbed saving, and simple field operation.

[0003] Currently, rice seedling transplanting is generally done manually or mechanically. Manual transplanting involves holding the seedling tray in the left hand and scattering the seedlings with the right. The heavier roots of the seedlings cause them to fall into the field. However, this method is laborious, and seedlings are prone to tilting, affecting their growth. Mechanical transplanting involves manually scattering seedlings onto the airflow of a machine. The airflow propels the seedlings upwards and to the side, allowing them to fall into the field under gravity. While this method relies on the heavier roots of the seedlings for free fall, it also suffers from the problem of seedlings tilting, which can negatively impact growth. Summary of the Invention

[0004] In view of this, the present invention provides a rice seedling shooter for rice planting.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] A rice seedling shooter, such as Figures 1-7 As shown, the device includes a frame 1, a support plate 2, a seedling frame 3, moving wheels 4, a pushing mechanism, an adjusting mechanism, and a guiding mechanism. The support plate 2 is connected to the top of the frame 1, and the seedling frame 3 is slidably connected to the support plate 2. The seedling frame 3 can slide back and forth along the support plate 2. Two moving wheels 4 are rotatably connected to the lower left side of the frame 1. Multiple material discharge ports are evenly spaced on the right side of the support plate 2. The lower right side of the seedling frame 3 is located to the left of the material discharge ports. The support plate 2 is provided with a pushing mechanism for pushing seedlings. The frame 1 is provided with an adjusting mechanism for driving the seedling frame 3 to move and adjust its position, and a guiding mechanism for guiding the seedlings.

[0033] like Figures 2-4 As shown, the feeding mechanism includes a guide frame 51, a small motor 52, a sliding rod 53, a separator frame 54, a cam 55, and a connecting rod 56. The front and rear sides of the right side of the support plate 2 are connected to the guide frame 51, and the front and rear sides of the bottom right side of the support plate 2 are both equipped with the small motor 52. A sliding rod 53 is slidably connected between the two guide frames 51. Multiple separator frames 54 are evenly spaced on the sliding rod 53. The number of separator frames 54 is the same as the number of discharge ports and is located above the discharge ports. A cam 55 is connected to the output shaft of each of the two small motors 52 so that the small motors 52 drive the cams 55 to rotate when they are in operation. The eccentric position of the cam 55 is hinged to the sliding rod 53 by a connecting rod 56 so that when the cam 55 rotates, it can pull the sliding rod 53 up and down through the connecting rod 56, thereby driving the separator frame 54 to move up and down reciprocally.

[0034] like Figure 3 As shown, the adjustment mechanism includes a dual-axis motor 61, a reciprocating lead screw 62, and a connecting plate 63. The dual-axis motor 61 is installed at the bottom center of the support plate 2. The output shafts on both sides of the dual-axis motor 61 are connected to reciprocating lead screws 62, and the threads of the two reciprocating lead screws 62 are aligned. The connecting plate 63 is connected to the reciprocating lead screw 62 by threads, so that when the reciprocating lead screw 62 rotates, it can drive the connecting plate 63 to move through the threads. The connecting plate 63 is slidably connected to the support plate 2 and connected to the seedling frame 3.

[0035] like Figures 5-7 As shown, the material guiding mechanism includes a guide rail 71, a slider 721, a discharge pipe 72, and a connecting hose 73. The guide rail 71 is connected to the right side of the frame 1. Sliders 721 are slidably connected to the guide rail 71 at even intervals. The number of sliders 721 is the same as the number of separators 54. The discharge pipe 72 is connected to the slider 721. A connecting hose 73 is connected between the discharge pipe 72 and the support plate 2. The connecting hose 73 communicates with the discharge port 11.

[0036] like Figures 8-10As shown, it also includes a pneumatic mechanism, which includes a cylinder body 81, a connecting frame 82, a connecting rod 83, an air outlet pipe 84, a first solenoid valve 851, a second solenoid valve 852, a piston plate 86, a one-way valve 861, a first contact sensor 862, and a second contact sensor 863. The support plate 2 has cylinder bodies 81 evenly spaced on its right side, the number matching the number of discharge pipes 72. An air outlet pipe 84 connects the lower part of each cylinder body 81 to the upper part of the discharge pipe 72. The sliding rod 53 has connecting frames 82 evenly spaced on its side, the number matching the number of separator frames 54. Connecting rods 83 are connected to the connecting frames 82, and piston plates 86 are connected to the bottom of the connecting rods 83. The piston plate 86 is slidably and sealed to the cylinder 81. A second solenoid valve 852 is installed on the upper part of the discharge pipe 72, and a first solenoid valve 851 is installed on the lower part of the discharge pipe 72. The connection between the air outlet pipe 84 and the discharge pipe 72 is located below the second solenoid valve 852. Two one-way valves 861 are provided on the piston plate 86. A second contact sensor 863 is provided in the upper part of the cylinder 81, and a first contact sensor 862 is provided in the lower part of the cylinder 81. A controller 87 is provided on the support plate 2. The first contact sensor 862, the second contact sensor 863, the first solenoid valve 851, and the second solenoid valve 852 are all electrically connected to the controller 87.

[0037] When it is necessary to plant rice seedlings, this rice seedling shooter can be used. Initially, the piston plate 86 contacts the contact sensor 863, and the solenoid valve 852 is in the open state. In use, first fix the left side of the frame 1 to the farm tractor, and then place the seedlings on the seedling rack 3. The seedlings will slide to the right on the seedling rack 3, and will slide to the right side of the support plate 2. Some seedlings will fall above the discharge port 11. Then, the small motor 52 can be controlled to drive the cam 55 to rotate. When the cam 55 rotates, it drives the sliding rod 53 to move up and down through the connecting rod 56. When the sliding rod 53 moves downwards... When the device moves downwards, it causes the separator 54 and connecting frame 82 to move downwards. As the separator 54 moves downwards, it separates the seedlings above the discharge port 11 from the other seedlings, allowing them to fall into the connecting hose 73 and the discharge pipe 72. At this time, solenoid valve 852 is closed, while solenoid valve 851 is open. The seedlings fall directly into the discharge pipe 72, with the upper part blocked by solenoid valve 852. When the connecting frame 82 moves downwards, it drives the piston plate 86 downwards via the connecting rod 83. As the piston plate 86 moves downwards, it disengages from contact sensor 863, at which point solenoid valve 852 closes. When the piston plate 86 moves downward, it compresses the gas in the cylinder 81 through the exhaust pipe 84 to the discharge pipe 72. When the piston plate 86 moves to contact the contact sensor 862, it sends a signal to the controller 87 to open the solenoid valve 851. If there are seedlings between the solenoid valve 852 and the solenoid valve 851, the gas in the discharge pipe 72 will compress the seedlings in the discharge pipe 72 downward, thus spraying them into the field to complete the seedling shooting operation. When the piston plate 86 moves upward and resets, it contacts the contact sensor 862 again to open the solenoid valve 851. When the contact sensor 863 is disconnected, the control solenoid valve 852 closes. At this time, the seedlings blocked by the solenoid valve 851 will fall into the discharge pipe 72. After the seedlings are shot, when new seedlings need to be added, the dual-axis motor 61 can be controlled to drive the reciprocating screws 62 on both sides to rotate, thereby driving the connecting plate 63 to move back and forth through the screw thread. When the connecting plate 63 moves, it can drive the seedling frame to move, adjust the position of the seedlings, so that the part with the seedlings moves back to the discharge port 11. Then, the seedlings are separated by the separator 54 and added. This process is repeated to realize the seedling shooting work.

[0038] like Figure 11 and Figure 12As shown, it also includes a synchronous adjustment mechanism, which includes a scissor-type telescopic frame 91, an internal threaded sleeve 92, and a threaded rod 93. The scissor-type telescopic frame 91 is installed between the tops of multiple sliders 721. The staggered point in the middle of the scissor-type telescopic frame 91 is connected to the top of the slider 721 so that the movement of the scissor-type telescopic frame 91 can drive the slider 721 to move, thereby adjusting the distance between the multiple sliders 721. The top center of the guide rail 71 is rotatably connected to the internal threaded sleeve 92. The threads on the left and right sides of the internal threaded sleeve 92 face opposite directions. The left and right sides of the internal threaded sleeve 92 are threadedly connected to the threaded rod 93. The threaded rods 93 on both sides are respectively connected to the staggered point in the middle of the two sides of the scissor-type telescopic frame 91 so that the movement of the threaded rod 93 can drive the scissor-type telescopic frame 91 to extend and retract.

[0039] When shooting seedlings, if it is necessary to adjust the spacing between seedlings, the inner threaded sleeve 92 can be rotated. When the inner threaded sleeve 92 rotates, the threaded rods 93 on both sides move closer or further apart through the thread. When the threaded rods 93 on both sides move, they can drive the scissor-type telescopic frame 91 to operate, thereby driving the slider 721 to move, so as to adjust the spacing between the sliders 721, thereby adjusting the spacing between the discharge pipes 72, and thus completing the adjustment of the seedling spacing, which is more convenient.

[0040] like Figure 13 and Figure 14 As shown, it also includes a smoothing mechanism, which includes a smoothing frame 101, screws 102 and guide plates 103. The front and rear sides of the frame 1 are each connected by two screws 102 by threads. The bottom of the two screws 102 is rotatably connected to the guide plates 103. The bottom of the two guide plates 103 is slidably connected to the smoothing frame 101.

[0041] When this rice shooter moves, the leveling frame 101 can be moved by the screw 102 and the guide plate 103. When the leveling frame 101 moves, it can level the farmland in the direction of movement, so as to avoid the farmland being uneven and affecting the rice shooting work.

[0042] like Figure 14 and Figure 15 As shown, it also includes a toggle mechanism, which includes a guide wheel 111, a connecting sleeve 112, and a sliding plate 113. The guide wheel 111 is connected to the center of the rear side of the front moving wheel 4. The guide wheel 111 has a guide groove 114. The connecting sleeve 112 is connected to the front top of the smoothing frame 101. The sliding plate 113 is slidably connected to the connecting sleeve 112. The sliding plate 113 is sleeved on the guide wheel 111. A convex shaft 115 is provided in the sliding plate 113. The convex shaft 115 of the sliding plate 113 is located in the guide groove 114, so that when the guide wheel 111 rotates, it can squeeze the convex shaft 115 through the guide groove 114 to drive the connecting sleeve 112 to move.

[0043] During the movement of this rice shooter, the rotation of the moving wheel 4 can drive the guide wheel 111 to rotate. When the guide wheel 111 rotates, it can drive the guide groove 114 to rotate. When the guide groove 114 rotates, it can squeeze the convex shaft 115, thereby driving the convex shaft 115 to move back and forth. When the convex shaft 115 moves, it can drive the smoothing frame 101 to move through the sliding plate 113 and the connecting sleeve 112, thereby causing the smoothing frame 101 to shake back and forth during the movement, which helps to smooth the farmland.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
