[0002] The motor control mechanism of the rice transplanter mainly includes the electric steering wheel system, electronic control operation, motor-driven lifting mechanism and other parts. Its main function is to achieve precise control of different components of the rice transplanter. For example, the electric steering wheel system provides accurate steering control, while the electronic control operating device and motor-driven lifting mechanism realize the automation and refined management of mechanical movements.

[0003] At present, high-speed rice transplanters on the market need to press the rice transplanting handle when transplanting rice, and the rice transplanter can only carry out the transplanting operation. In particular, the rice transplanting operation requires frequent turning or stopping to add rice seedlings, and the rice transplanting handle needs to be lifted. Therefore, users need to press and lift the rice transplanting handle frequently and a lot when transplanting rice seedlings. Such operation for a long time will increase the labor intensity of the driver's operation of the machine. Now a mechanism is designed that can cancel the rice transplanting handle and use an electric device to control the rice transplanting to solve this technical defect problem. Utility Model Content

[0019] To enable those skilled in the art of this technology to better understand the solutions of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings 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 creative efforts shall fall within the scope of protection of this application.

[0020] The following further illustrates the technical solutions of the present utility model with reference to the drawings. Figures 1-5A motor control mechanism for a rice transplanter is shown, which includes a right-angle motor 101, a toothed plate 102, an angle sensor 103, a pull plate 104, a support plate 105, a transplanting rotating shaft plate 106, a fixed seat 107, a pull rod 108, a transmission assembly, a pull arm 113, a separating pin 114 and a gearbox 115. There is an electrical connection between the right-angle motor 101 and the angle sensor 103. The support plate 105 is installed on one side of the frame 109, and the fixed seat 107 is installed on the other side of the frame 109. The right-angle motor 101 is installed at the bottom on one side of the support plate 105. The transplanting rotating shaft plate 106 is arranged outside the fixed seat 107, and its rotating shaft I sequentially passes through the round holes on the fixed seat 107 and the support plate and is rotationally received. The angle sensor 103 is fixedly arranged on the other side of the support plate 105, and its rotating shaft II passes through the round hole on the support plate 105 and is rotationally received. A gear is installed on the output shaft of the right-angle motor 101, which is meshed with the teeth at the bottom of the toothed plate 102. A flat hole is provided in the middle of the toothed plate 102 and sleeved on the rotating shaft I. A flat hole is provided at the bottom of the pull plate 104 and sleeved on the rotating shaft II. Holes are provided at the tops of the toothed plate 102 and the pull plate 104, and the two bent ends of the pull rod 108 are respectively inserted into the above holes to fixedly connect them. The transplanting rotating shaft plate 106 is connected to one end of the pull arm 113 through the transmission assembly. The middle of the pull arm 113 is hinged to the lug of the gearbox 115. The other end of the pull arm 113 is rotationally clamped to the separating pin 114. The other end of the separating pin 114 is fitted and installed in the gearbox 115, and it is inserted and pulled out for separating and combining the transplanting power in the gearbox 115.

[0021] By driving the toothed plate 102 to rotate with the right-angle motor 101, and then driving the angle sensor 103 and the transmission assembly respectively, using the transmission assembly, the pull arm and the separating pin, the separation and combination of the transplanting power in the gearbox 115 are realized, and the measured angle value is fed back to the right-angle motor 101 by the angle sensor to control its stop rotation, so as to drive and replace the pressing of the transplanting handle to perform the transplanting operation.

[0022] In order to smoothly insert and pull out the separating pin 114 from the gearbox 115, the rotational clamping connection between the pull arm 113 and the separating pin 114 is set to be more stable, such as Figure 4 , the other end of the pull arm 113 is provided with two circular claws, and one end of the separating pin 114 is provided with an annular groove, and the two circular claws are rotationally clamped in the annular groove.

[0023] The angle sensor 103 measures the angle values of three gears, namely transplanting, neutral and rising, when the toothed plate 102 rotates. When the corresponding angle value of each gear is reached, it is fed back to the controller 116 and an instruction is issued to make the right-angle motor 101 stop rotating.

[0024] As an embodiment of the present utility model, the transmission assembly includes a connecting rod 110, a swing arm plate 111 and a ball head rod assembly 112. Two ends of the connecting rod 110 are respectively arranged on an insertion rotation shaft plate 106 and the swing arm plate 111. The middle part of the swing arm plate 111 is hinged to a frame 109. A ball head rod assembly 112 is arranged between the swing arm plate 111 and a pull arm 113.

[0025] The working principle of the present utility model:

[0026] As Figures 1-3 , there are three electric control buttons (not indicated in the text and drawings) for insertion, neutral and lifting near the instrument panel at the steering wheel. For example: when the insertion button is pressed, an electric control signal is transmitted to a right-angle motor 101 through a controller 116. The right-angle motor 101 rotates clockwise, and then drives a toothed plate 102 to rotate counterclockwise, which can drive the insertion rotation shaft plate 106, further push the connecting rod 110 to move downward, push the swing arm plate 111 to rotate forward, and further act through the ball head rod assembly 112 and the pull arm 113 to pull a separating pin 114 outward, so that the clutch power of the insertion power inside a transmission 115 is combined and transmitted to the power of a rice transplanter table.

[0027] On the contrary, controlling the motor 101 to rotate counterclockwise will push the separating pin 114 into the transmission 115 inward, so that the clutch power of the insertion power inside the transmission 115 is separated to cut off the insertion power. The function of an angle sensor 103 is to respectively measure the angle values of three gears of insertion, neutral and lifting when the toothed plate 102 rotates. When the right-angle motor 101 is at the angle values corresponding to the three gears, the angle values will be fed back to the controller 116, and the controller 116 issues an instruction to make the control motor 101 stop rotating.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
