[0019] Compared with the prior art, the technical scheme provided in the application has the following beneficial effects:

[0020] This utility model provides a control and drive module for a rice transplanter that integrates an angle sensor, transmission gears, and a drive motor into a single module via an integrated base. Compared to existing technologies, this eliminates three angle transmission components, effectively simplifying the structure of existing angle detection and transmission devices.

The control and drive module is mounted entirely on a mounting plate; if any component malfunctions and requires repair, the rice transplanter can be directly connected to the mounting plate. The control drive module is completely disassembled and replaced with a spare control drive module for the rice transplanter. Transplanting operations and control drive module maintenance can be performed simultaneously, reducing downtime and effectively improving transplanter efficiency. The control drive module uses a detachable installation method, secured to the mounting plate via base supports. It can be installed directly without disassembling other adjacent components, avoiding the cumbersome operation of disassembling or installing angle detection transmission devices that requires removing adjacent parts in existing technologies. Similarly, disassembly can be completed quickly and easily. This simple connection method saves installation and disassembly time, further reducing downtime and contributing to increased transplanter efficiency. This utility model provides a method for coaxially and fixedly connecting the gear hub of the transmission gear and the angle input shaft of the angle sensor in a control drive module for a rice transplanter. Compared with the existing connection method of the transmission gear and the angle input shaft of the angle sensor, where the angle generated by the rotation of the transmission gear needs to be transmitted through three components—an angle positioning arm, a connecting rod, and an angle transmission arm—this new method eliminates the need for circumferential transmission, reducing the error-causing links and effectively improving the accuracy of the transmission gear rotation angle measurement. The transmission sleeve is designed to increase the compatibility between the angle input shaft and the gear hub, thereby accurately transmitting the rotation angle of the transmission gear to the angle sensor. It also protects the high-value precision component, the angle input shaft of the angle sensor, reducing wear and extending the service life of the angle sensor. The oil-free bushing in the control drive module for a rice transplanter provided by this utility model is designed to reduce the friction between the gear hub and the bushing during the rotation of the transmission gear, thereby improving the output efficiency of the drive motor. The circumferential groove, limit clip, and bushing are fixedly connected to the gear hub and the angle input shaft, while restricting the axial movement of the transmission gear and the oil-free bushing.

As the core component of the control drive module for the rice transplanter, the integrated base is integrally stamped and formed, requiring only one bending process during manufacturing, which is highly efficient, has a high utilization rate of stamping forming materials, and has a low overall manufacturing cost.

[0042] Embodiment 1

[0043] Referring to Figures 2-11 The utility model discloses a control drive module for rice transplanter provides, mainly includes drive motor 4, transmission gear 2, angle sensor 1 and integrated base 5, and the drive gear 41 of drive motor 4 is mutually engaged with transmission gear 2, and the bolt 9 passes through the bolt hole on integrated base 5 and is with the shell of drive motor 4 screw joint, thereby fixed drive motor 4 on integrated base 5. The meshing position of drive gear 41 and transmission gear 2 is corresponded to the position of integrated base 5 and is provided with gear window 522, is used to observe the meshing condition of drive gear 41 and transmission gear 2. Before control drive module for rice transplanter is installed, according to the meshing condition of drive gear 41 and transmission gear 2 observed by gear window, judges whether the tooth gap of drive gear 41 and transmission gear 2 needs to be adjusted.

[0044] The gear hub 23 of the transmission gear 2, which is in engagement with the driving gear 41, is inserted through the circular base shaft hole 523, which is formed in the base plate 52 of the integrated base 5, and the angle input shaft 11 of the angle sensor 1.

[0045] Specifically, as shown in Figure 6 The integrated base 5 is provided with an L-shaped sensor bracket 521, which is integrally formed on the integrated base plate 52. The sensor bracket 521 is used to install the angle sensor 1 in parallel with the main plane of the integrated base 5 and the transmission gear 2. Moreover, the plane of the sensor bracket 521 is concave semicircular in shape to match the shape of the angle sensor 1. When the angle sensor 1 is fixed to the sensor bracket 521 by the bolt 9, the sensor bracket 521 and the angle sensor 1 are completely fitted and do not vibrate, which can improve the accuracy of the angle sensor measurement. Specifically, the bolt 9 is screwed through the through holes of the two fixed ear plates 12 on the housing of the angle sensor 1 and the sensor bracket 521. The L-shaped sensor bracket 521 can also be welded to the integrated base 5.

[0046] The outer periphery of the base shaft hole 523 is welded with a circular ring-shaped shaft sleeve 51, and the center of the base shaft hole 523 is on the central axis of the shaft sleeve 51, that is, the base shaft hole 523 and the shaft sleeve 51 are coaxial. The shaft sleeve 51 can effectively prevent the circumferential swing of the transmission gear 2, further improving the accuracy of the angle measurement of the transmission gear 2. The shaft sleeve 51 can also be welded to the inner ring of the base shaft hole 523.

[0047] As shown in Figure 5 The gear hub 23 and the shaft sleeve 51 are provided with a circular ring-shaped oil-free bushing 6, which can reduce the circumferential friction of the transmission gear 2 during rotation and improve the output efficiency of the driving motor 4. The inner surface of the oil-free bushing 6 can also be shaped to match the shape of the gear hub 23. As shown in Figure 9 The gear hub 23 is a stepped shaft, and the shaft surface is provided with a circumferential clamping groove 22 that cooperates with the limiting clamp 3. The limiting clamp 3, the circumferential clamping groove 22, and the shaft sleeve 51 combine to fix the gear hub and the angle input shaft 11, while limiting the axial movement of the transmission gear 2 and the oil-free bushing 6, and fixing the transmission gear 2 on the integrated base 5.

[0048] As shown in Figure 7 and Figure 8As shown, the angle input shaft 11 of the angle sensor 1 is a double flat shaft, and the gear hub 23 has a circumferential clamping groove 22 on one side end face, and a double flat hole is formed in the double flat hole, which is matched in size and shape with the double flat shaft of the angle input shaft 11, that is, the gear hub 23 is circumferentially fixed and axially inserted with the angle input shaft 11. The transmission sleeve 10 can also be provided between the angle input shaft 11 and the gear hub 23. The transmission sleeve 10 has a double flat hole, which is matched in size and shape with the double flat shaft of the angle input shaft 11; the other side of the transmission sleeve 10 is a double flat shape, which is matched in size and shape with the double flat hole of the gear hub 23, and is embedded in the double flat hole of the gear hub 23, so that the transmission sleeve 10 and the transmission gear 2 rotate synchronously. The transmission sleeve 10 is made of relatively soft plastic material, and the transmission sleeve 10 can be replaced after wear, so as to protect the high-value precision components, that is, the angle input shaft 11 of the angle sensor 1, and avoid the angle input shaft 11 being worn by the gear hub 23. The double flat hole of the transmission sleeve 10 can also be a through hole.

[0049] The other side end face of the gear hub 23 is also provided with a double flat hole, which is matched in size and shape with the one side double flat shaft of the power transmission shaft 8, that is, the gear hub 23 is circumferentially fixed and axially inserted with the power transmission shaft 8, and the drive gear 41 can transmit torque to the power transmission shaft 8 through the transmission gear 2, and then drive the movement of other components. The gear hub 23 and the power transmission shaft 8 can also be connected in other shapes, such as spline connection. In order to save process, the two sides of the gear hub 23 are double flat through holes with the same size, shape and direction; in order to adapt to the power transmission shaft 8 and the angle input shaft 11, the two sides of the gear hub 23 can also be different in size, shape and direction.

[0050] When the rice transplanter control drive module is running, the drive gear 41 of the drive motor 4 drives the transmission gear 2 to rotate, the transmission gear 2 transmits torque to the angle sensor 1 and the power transmission shaft 8 through the gear hub 23, and the torque is finally transmitted to the planting part. When the angle sensor 1 measures the rotation angle corresponding to the set height of the planting part, the angle sensor sends a signal to the controller, and the controller sends a stop signal to the drive motor, and the drive motor stops driving.

[0051] The base plate 52 of the integrated base 5 is also provided with a base leg 524, and a nut 53 is welded on the base leg 524. The bolt 9 can be screwed with the welded nut 53 on the base leg 524, so as to fix the rice transplanter control drive module on the mounting plate 7. The mounting plate 7 is rectangular, and the opposite two sides of the mounting plate 7 have two same direction folding edges, and the depth of the folding edge is determined according to the specific rice transplanter. The rice transplanter control drive module is installed on the same side of the folding edge of the mounting plate 7.

[0052] A circular hole is provided on the gear hub 23 at the position corresponding to the mounting plate 7. The power transmission shaft 8 passes through the circular hole and is fixedly connected to the gear hub 23. When the rice transplanter control drive module is completely disassembled, the power transmission shaft 8 and the gear hub 23 can be directly separated without disassembling the power transmission shaft 8. During installation, it is only necessary to align the power transmission shaft 8 with the gear hub 23 and insert it for screw connection and fixation.

[0053] The integrated base 5 is a welded component, requiring only the bushing 51 and nut 53 to be welded to the base substrate 52. The base substrate 52 is a one-piece stamped part, requiring only one bending process during manufacturing, resulting in high efficiency, low cost, and high utilization of stamping materials, effectively reducing waste and further lowering costs. Simultaneously, the integrated base 5 integrates power drive, power transmission, detection control, and installation functions into one unit, with a simple structure and easily replaceable components.

[0054] In this embodiment, the drive motor 4 and the angle sensor 1 are both commercially available conventional electrical components.

[0055] Example 2

[0056] Embodiment 2 of this utility model provides a rice transplanter, such as Figure 12 As shown, the system includes a frame 15, on which an air duct 14 is mounted. A mounting plate 7 is fixedly connected to both the frame 15 and the air duct 14. The mounting plate 7 has two folded edges perpendicular to the frame 15 and the air duct 14. Two opposing mounting plates 7 are mounted on the frame 15, with a battery placed between them. These plates also support the driver's seat of the rice transplanter. One of the mounting plates 7 has a folded edge on one side, where the rice transplanter drive control module 13 from Embodiment 1 is mounted. A power transmission shaft 8 passes through the mounting plate 7 and connects to the gear hub 23 of the drive gear 2 in the rice transplanter drive control module 13. The specific connection method is the same as in Embodiment 1. The mounting plate 7, the battery, the folded edges of the mounting plate 7, the frame 15, and the air duct 14 restrict the rice transplanter control drive module from six directions. Therefore, the shape and size of the rice transplanter control drive module must be adapted to the space where it is installed. The mounting plate 7, integrated base 5, side folds of the mounting plate 7, frame 15, and air duct 14 protect the control drive module of the rice transplanter from six directions, preventing interference from other components or foreign objects. This reduces factors affecting measurement accuracy and minimizes damage that could lead to maintenance issues. If the components are installed in a separate measurement manner as in existing technology, the angle is transmitted through three components. This indirect measurement not only increases the accuracy of angle measurement itself, but also makes the three components susceptible to interference from other components, further increasing the error in angle measurement. Furthermore, without the protection of the integrated base, foreign objects can damage the drive control module from the battery side.

[0057] When the control driving module of the rice transplanter fails, the control driving module of the rice transplanter can be directly disassembled and replaced using the electric screwdriver, the standby maintenance time of the rice transplanter is reduced, the rice transplanting efficiency is effectively improved, the disassembly and assembly are simple and convenient, the control driving module of the rice transplanter can be directly screwed from the outside, and other components of the accessories do not need to be disassembled in advance. After the control driving module of the rice transplanter fails, it does not need to be discarded as a whole, and the faulty components, such as the driving motor 4, the transmission gear 2 and the angle sensor 1, can be directly repaired or replaced.

[0058] The technical features of the above-described embodiments can be combined in any manner, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0059] The above-described embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
