The Hall sensor, the inputtable counting relay and the control system are connected in sequence.

The seedling taking device can move to the lowest point once in a complete working cycle process, as shown in figure 4, which is a working curve chart of the seedling taking device. The number of the transplanted seedlings can be obtained by theoretically calculating the working cycle times of the seedling taking device without considering the empty transplanting condition caused by the fact that the seedling taking device does not take the seedlings. In the actual working process, the seedling taking device can be directly contacted with muddy water and the like, so that the working environment is quite severe, and the normal work of the Hall sensor can be influenced. And installation of related devices cannot be realized due to limited installation space. The inserting shaft is higher away from the ground, the working environment is relatively better, the installation space is large, and the Hall sensor is suitable for installation and signal acquisition.
In order to achieve the purpose of counting by utilizing the rotation turns of the transplanting shaft, the transmission relationship between the transplanting shaft and the seedling taking device needs to be researched. The photoelectric sensor is used for collecting signals of the position of the seedling taking device running to the lowest point, the Hall sensor is used for collecting the number of rotating circles of the transplanting shaft, and the signals collected by the photoelectric sensor and the Hall sensor are recorded and processed through the double-channel logic analyzer. Carry out a large amount of experiments to getting seedling ware and transplanting a plant the axle drive ratio through measuring circuit, obtain through experimental result analysis: in the practical working process of the rice transplanter selected by the embodiment, the rice seedling taking device and the transplanting shaft are driven according to the transmission ratio of 1:1 in the movement process. In the process of transplanting rice seedlings, the number of turns of the transplanting shaft is equal to the number of the movement cycles of the rice seedling taking device, and the number of the rice seedlings transplanted by the rice transplanter is equal to the number of the rice seedlings transplanted by the rice seedling transplanting machine under the condition of neglecting the empty transplanting of the rice seedling taking device.
The rice transplanter selected by the embodiment has the function of automatically lifting the seedling box during the running in a reverse mode, and when the rice transplanter runs in the reverse mode, the lifting circuit relay receives a reverse running signal and then is connected with the seedling box lifting circuit, so that the seedling box is lifted, and the sampler stops moving. In order to stop the transplanting operation of the rice transplanter when the counter reaches the number of the rice seedlings preset by the driver, a lifting circuit of the rice seedling box needs to be controlled. The counter is used for counting the signals collected by the Hall sensor, when the number of the seedlings preset by the counter is reached, the counter outputs a pulse to a lifting relay of the seedling box, so that a lifting circuit is switched on, the seedling box is lifted, and meanwhile, the seedling taking device stops the actions of taking and transplanting the seedlings, thereby completing the quantitative seedling transplanting operation.
In the process of mounting the Hall sensor on the transplanting shaft, different mounting positions can ensure that different phase differences theta exist between the phase phi of the signals of the transplanting shaft collected by the Hall sensor and the phase lambda of the signals of the seedling taking device moving to the lowest point, namely, the theta is phi-lambda. In this case, the value of θ is equal to or less than 0 and equal to or greater than 0. When theta is less than or equal to 0, namely the signals of the Hall sensors are before the signals of the lowest points of the seedling taking devices, the seedling transplanting is completed after counting is completed, so that the counting is completed when the last seedling is not transplanted, and one seedling is not transplanted; when theta is larger than 0, namely after the signal of the Hall sensor is at the lowest point of the seedling taking device, the counting is finished after the seedling transplanting is finished, and the situation of less transplanting of a seedling can not happen at the moment.
In order to solve the problem of installation position of the hall sensor, an installation and debugging module part based on an encoder is designed, and is a schematic diagram of a synchronous rotating mechanism based on the encoder as shown in fig. 5. A pair of meshed gears (a first gear and a second gear) with a transmission ratio of 1:1 is arranged on an transplanting shaft to drive an encoder, the second gear, the first gear and the transplanting shaft to synchronously rotate, so that phi and lambda are collected, and the phase difference theta between the phi and the lambda is calculated. Fig. 6 shows a debug circuit diagram. For the purpose of accurate counting, the installation position of the hall sensor needs to be adjusted so that the difference between phi and lambda is 180 degrees, namely thetaa180. Referring to the rotation direction of the insertion shaft, the angle theta that the Hall sensor should rotate at the momenttComprises the following steps:
1) when 0 is<When theta is less than or equal to 180 degrees, the angle which the Hall sensor should rotate at the moment is thetat＝θa- θ, in a direction opposite to the rotation direction of the implant shaft;
2) when 180 is used<When theta is less than or equal to 360 degrees, the angle which the Hall sensor should rotate at the moment is thetat＝θ-θaThe direction is along the rotating direction of the transplanting shaft;
3) when theta is more than or equal to minus 180 and less than or equal to 0, the angle which the Hall sensor should rotate at the moment is thetat＝θa- θ, in a direction opposite to the rotation direction of the implant shaft;
4) when theta is more than or equal to-360 and less than or equal to-180, the angle which the Hall sensor should rotate is thetat＝θa- θ, in the opposite direction to the rotation of the implant shaft.
FIG. 7 is a graph showing the relationship between φ and λ at a certain position of the Hall sensor on the implant shaft. The upper line shows phi, the lower line shows lambda, and the phase difference theta is-160.31 degrees, which meets the first conditionIf the Hall sensor should be rotated by an angle thetat＝θa- θ 180+160.31 340.31, in the opposite direction to the rotation of the implant shaft. The installation position of the permanent magnet of the Hall sensor is adjusted according to the result, so that the counting is completed after the seedling transplanting is completed, and the condition of less transplanting of a seedling can be avoided.
Except for the mode mentioned in the embodiment, when the transmission ratio of the transplanting shaft and the seedling taking device is other proportion, only the counting relay capable of inputting is needed to be calibrated, for example, when the proportion is 1:2, every 1 group of Hall sensor signals completes 2 times of counting.
The above embodiments are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents thereof, and all such changes, modifications, substitutions, combinations, and simplifications are intended to be included in the scope of the present invention.
