Description

Specifically, when the angle sensor measures that the rotation angle corresponding to the lifting height of the planting unit reaches the set value, 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.

[0004] However, in the technical solution of the above patent, Figure 1 As shown, when the angle sensor measures the rotation angle of the transmission gear, the rotation of the transmission gear drives the angle positioning arm, the angle positioning arm drives the connecting rod, the connecting rod drives the angle transmission arm, the angle transmission arm rotates the angle input shaft of the angle sensor, and the angle input angle sensor generated by the rotation of the transmission gear needs to be transmitted through three components, which increases the complexity of the angle detection transmission device. The precision of the angle sensor and the drive motor and the complexity of the angle detection transmission device make the angle detection transmission device extremely susceptible to damage due to the harsh working environment of the rice transplanter, and the complexity of the structure also leads to a lot of time required for disassembly and maintenance, which seriously affects the operating efficiency of the rice transplanter.

[0044] Example 1

[0045] See also Figures 2 to 11 Embodiment 1 of the present invention provides a control drive module for a rice transplanter, which mainly includes a drive motor 4, a transmission gear 2, an angle sensor 1 and an integrated base 5. The drive gear 41 of the drive motor 4 meshes with the transmission gear 2, and the bolt 9 passes through the bolt hole on the integrated base 5 and is screwed to the housing of the drive motor 4, thereby fixing the drive motor 4 on the integrated base 5. A gear window 522 is provided at the meshing position of the drive gear 41 and the transmission gear 2 corresponding to the position of the integrated base 5, for observing the meshing condition of the drive gear 41 and the transmission gear 2. Before installing the control drive module for a rice transplanter, it is determined whether the tooth clearance between the drive gear 41 and the transmission gear 2 needs to be adjusted according to the meshing condition of the drive gear 41 and the transmission gear 2 observed through the gear window.

[0046] The gear hub 23 of the transmission gear 2 that is in meshing state with the driving gear 41 passes through a circular base shaft hole 523 provided on the base substrate 52 of the integrated base 5 and is plugged into the angle input shaft 11 of the angle sensor 1 .

[0047] Specifically, Figure 6 As shown, an integrated L-shaped sensor bracket 521 is provided on the integrated substrate 52. The plane of the sensor bracket 521 used to install the angle sensor 1 is parallel to the main plane of the integrated base 5, and is also parallel to the transmission gear sheet 21 of the transmission gear 2. Moreover, the shape of the plane of the sensor bracket 521 is a concave semicircle to adapt to the shape of the angle sensor 1. When the angle sensor 1 is fixed to the sensor bracket 521 with bolts 9, the seat bracket 521 is completely fitted with the angle sensor 1 without vibrating, which can improve the accuracy of the angle sensor measurement. Specifically, the bolts 9 pass through the through holes of the two fixing ear plates 12 arranged oppositely on the housing of the angle sensor 1 and are screwed to the sensor bracket 521. The L-shaped sensor bracket 521 can also be welded to the integrated base 5.

[0048] A circular sleeve 51 is welded to the outer periphery of the base shaft hole 523, and the center of the base shaft hole 523 is on the central axis of the sleeve 51, that is, the base shaft hole 523 and the sleeve 51 are coaxial. The sleeve 51 can effectively prevent the circumferential swing of the transmission gear 2, and further improve the accuracy of the measurement of the rotation angle of the transmission gear 2. The sleeve 51 can also be welded in the inner circle of the base shaft hole 523.

[0049] like Figure 5 As shown, an annular oil-free bushing 6 is provided between the gear hub 23 and the shaft sleeve 51. The oil-free bushing 6 can reduce the circumferential friction force when the transmission gear 2 rotates, and improve the output efficiency of the drive motor 4. The inner surface shape of the oil-free bushing 6 can also be set to other shapes that are compatible with the gear hub 23. Fig. 9 As shown, the gear hub 23 is a stepped shaft, and a circumferential groove 22 that cooperates with the limit card 3 is provided on the shaft surface. The limit card 3, the circumferential groove 22 and the shaft sleeve 51 are combined to form a fixed connection between the gear hub and the angle input shaft, while limiting the axial movement of the transmission gear 2 and the oil-free bushing 6, and also fixing the transmission gear 2 on the integrated base 5.

[0050] like Figure 7 and Figure 8As shown, the angle input shaft 11 of the angle sensor 1 is a double-flat shaft shape, and the gear hub 23 has a circumferential groove 22 on one side of the end surface with a double-flat inner hole, which is compatible with the double-flat shaft shape of the angle input shaft 11, that is, the gear hub 23 is circumferentially fixed and axially plugged with the angle input shaft 11. A transmission sleeve 10 can also be arranged between the angle input shaft 11 and the gear hub 23, and the transmission sleeve 10 has a double-flat inner hole, which is compatible with the double-flat shaft shape of the angle input shaft 11; the circumferential surface of the other side of the transmission sleeve 10 is a double-flat outer shape, which is compatible with the double-flat inner hole size and shape of the gear hub 23, and is embedded in the double-flat inner hole of the gear hub 23, so as to realize the synchronous rotation of the transmission sleeve 10 and the transmission gear 2. The transmission sleeve 10 is made of relatively soft plastic material, and the transmission sleeve 10 can be replaced after being worn, so as to protect the high-value precision component, that is, the angle input shaft 11 of the angle sensor 1, and prevent the angle input shaft 11 from being worn by the gear hub 23. The double-flat inner hole of the transmission sleeve 10 may also be a through hole.

[0051] The other side end face of the gear hub 23 is also provided with a double flat inner hole, which is matched with the size and shape of the double flat shaft on one side of the power transmission shaft 8, that is, the gear hub 23 is circumferentially fixed and axially plugged with the power transmission shaft 8, and the driving gear 41 can transmit torque to the power transmission shaft 8 through the transmission gear 2, thereby driving the movement of other components. The gear hub 23 and the power transmission shaft 8 can also be connected in other shapes, such as a spline connection. In order to save process, the double flat inner holes on both sides of the gear hub 23 are double flat through holes of the same size, shape, and direction; in order to adapt to the power transmission shaft 8 and the angle input shaft 11, the inner holes on both sides of the gear hub 23 can also be of different sizes, shapes, and directions.

[0052] When the control drive module of the rice transplanter is running, the driving gear 41 of the driving motor 4 drives the transmission gear 2 to rotate, and the driving gear 2 transmits the torque to the angle sensor 1 and the power transmission shaft 8 respectively 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 when the planting part is lifted, the angle sensor sends a signal to the controller, and the controller sends a stop signal to the driving motor, and the driving motor stops driving.

[0053] The base substrate 52 of the integrated base 5 is also provided with a base support foot 524, on which a nut 53 is welded, and a bolt 9 can be used to screw with the welded nut 53 on the base support foot 524, so as to fix the control drive module for the rice transplanter on the mounting plate 7. The mounting plate 7 is rectangular, and the opposite sides of the mounting plate 7 have two folded edges in the same direction, and the depth of the folded edges is determined according to the specific situation of the rice transplanter. The control drive module for the rice transplanter is installed on the same side of the folded edge of the mounting plate 7.

[0054] A circular hole is provided at the position of the gear hub 23 corresponding to the mounting plate 7, and the power transmission shaft 8 passes through the circular hole and is fixedly connected to the gear hub 23. When the control drive module for the rice transplanter is disassembled as a whole, the power transmission shaft 8 is directly separated from the gear hub 23 without disassembling the power transmission shaft 8; during installation, the power transmission shaft 8 only needs to be aligned with the gear hub 23 and inserted for screwing and fixing.

[0055] The integrated base 5 is a welded component, and only the sleeve 51 and the nut 53 need to be welded to the base substrate 52. The base substrate 52 is an integral stamping part, and only one bending process is required during the manufacturing process, which is efficient and low cost. In addition, the utilization rate of stamping materials is high, which effectively reduces waste generation and further reduces costs. At the same time, the integrated base 5 integrates power drive, power transmission, detection control and installation functions into one, with a simple structure and easy replacement of components.

[0056] The driving motor 4 and the angle sensor 1 in this embodiment are both conventional electrical components available on the market.

[0057] Example 2

[0058] Embodiment 2 of the present invention provides a rice transplanter, such as Fig.12 As shown, it includes a frame 12, on which an air duct 11 is arranged, a mounting plate 7 is fixedly connected to the frame 12 and the air duct 11 at the same time, and the mounting plate 7 has two edges with the same folding edges that are perpendicular to the frame 12 and the air duct 11. Two mounting plates 7 are arranged opposite to each other on the frame 12, and the middle of the two mounting plates is used to place the battery, and the two mounting plates can also play the role of supporting the driving seat of the rice transplanter. The driving control module 13 for the rice transplanter in Example 1 is installed on one side of the mounting plate 7 with the folding edge, and the power transmission shaft 8 passes through the mounting plate 7 and is connected to the gear hub 23 of the driving gear 2 in the driving control module 13 for the rice transplanter. The specific connection method refers to the corresponding connection method in Example 1. The mounting plate 7 and the battery, the folding edges on both sides of the mounting plate 7, the frame 12 and the air duct 11 respectively restrict the control driving module for the rice transplanter from 6 directions, so the shape and size of the control driving module for the rice transplanter must be adapted to the space where the installation position is located. The mounting plate 7 and the integrated base 5, the folded edges on both sides of the mounting plate 7, the frame 12 and the air duct 11 protect the control drive module for the rice transplanter from 6 directions respectively, to prevent other components or foreign objects from interfering with the precision components of the control drive module for the rice transplanter, which not only reduces the factors affecting the measurement accuracy, but also reduces the damage factors that lead to maintenance. If each component is installed according to the split measurement method in the prior art, the angle is transmitted through three components. This indirect measurement will not only increase the accuracy of the angle measurement itself, but also the three components are easily interfered by other components, further increasing the error of the angle measurement. At the same time, without the protection of the integrated base, foreign objects will also damage the drive control module from the battery side.

[0059] When the control drive module for the rice transplanter fails, the control drive module for the rice transplanter can be directly disassembled and replaced as a whole using an electric screwdriver, which reduces the standby maintenance time of the rice transplanter and effectively improves the efficiency of rice transplanting. Moreover, the disassembly and assembly is simple and convenient, and the control drive module for the rice transplanter can be disassembled and assembled directly by screwing the bolts from the outside without removing other parts of the accessories in advance. When the control drive module for the rice transplanter fails, it does not need to be discarded as a whole, and the faulty components, such as the drive motor 4, the transmission gear 2, the angle sensor 1, etc., can be directly repaired or replaced.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
