Abstract:
This invention belongs to a seedling separating device based on a rack and pinion drive in the field of transplanting machine in the agricultural automation facility, including a rack, a power unit, a linear drive, a number of seedling cups and a cylinder pushing device. The linear actuator is driven by the power unit to move on the frame; these seedling cups are mounted on the linear drive; the cylinder pushing device is mounted on the frame and is located behind the seedling cups and it drives the lower part of the seedling cup to open and retracts to close. The seedling device has simple structure, controllable program and high reliability. The motor drives the seedlings cups to move left and right; the cylinder pushes the cups to be opened and closed; the trust cup is straight down, the seedling attitude is better and the location of seedling can also be adjusted. The device can not only achieve the exact location in the designated seedling, but also to achieve the seedling movement of separating seedlings to two points from the mouth of the seedling cups.

Claim (Index 1):
A seedling separating device based on the rack and gear drive, which comprises\n a frame; a power device; a linear transmission device; a plurality of cups; a cylinder pushing device; and a control system; and a sensor and a sensor holder mounted on the frame; one end of the sensor holder is mounted on the frame through a sensor mounting hole; wherein the sensor is mounted on the other end of the sensor holder; wherein the power device includes a motor connection plate, a gear, a sleeve and a motor; wherein the motor is fixed on the upper end of the motor connection plate; the shaft sleeve is arranged on the rotation shaft of the motor and is fixedly connected with the motor; the lower end of the gear is braced and fixedly connected with the rotating shaft of the motor; wherein the linear transmission device includes a cup holder, cup mounting holes, a slider connecting plate, a slider, a cup connecting plate and a linear guide; wherein the linear guide is fixed to the frame through a linear guide mounting hole; wherein the slider is mounted within a linear guide; wherein the slider connecting plate is mounted on the slider by screws; wherein the cup connection plate is provided with through holes and is located between the slider connecting plate and the cup holder; wherein the slider connecting plate is connected with the cup holder by screws; wherein the cup holder is provided with a plurality of cup mounting holes; wherein the seedling cups are mounted on a cup holder by screws; the rack is fixed to the frame through a rack mounting hole and is meshed with the gear; wherein the cylinder pushing device is mounted on the frame and is located behind the cups; wherein the cylinder pushing device drives the lower part of the cup to open and retracts it to close; wherein the control system comprises a PLC central control unit, a data acquisition unit and a device execution unit; wherein the data acquisition unit comprises sensors; wherein the PLC central control unit comprises a motor control module and a cylinder control module; wherein the device execution unit comprises a motor and a cylinder; wherein the motor control module comprises a motor control module and a cylinder control module; wherein the PLC central control unit is respectively connected with the data acquisition unit and the device execution unit; wherein the photoelectric sensor is used for sensing whether the motor reaches the set position and then transmitting the induction signal to the PLC central control unit; wherein the motor control module controls the motor to stop or advance according to the signal; and wherein the cylinder control module controls the cylinder according to the signal to open or close the lower end of the seedling cup.
