Technical field

The invention relates to a seed coating device for laboratory use, belonging to the technical field of scientific research experimental devices.

Background technique

Sowing is an important step in crop production, but the processing of seeds before sowing is also very important. The quality of crop seeds directly affects the growth of the crops. After seeds are sown, they are easily eroded by pathogens in the soil, seriously affecting the quality of the seeds. Survival rate. In response to the damage caused by the above diseases and insect pests, a commonly used method is to coat the seeds before sowing. The coated seeds are drought-resistant and cold-resistant, which is conducive to early germination of seeds and ensures high crop emergence rate, strong seedlings, and uniform seedlings. And prevent diseases and insects. The most traditional coating method is manual seed dressing. However, this method not only increases labor intensity, but also has many safety hazards.

Working principle of the invention:

The initial state of the first step: open the spherical seed chamber and load the seeds to be coated. At this time, the spherical seed chamber is separated from the frame, the T-shaped magnet rotating shaft of the support arm is in a contracted state, and the hook and hanging ring at the lower part of the turntable are in detached state. Then hold the spherical seed chamber with your hands so that the spherical seed chamber is between the support arms on both sides.

The second step is to energize the electromagnetic coil and control the current direction of the electromagnetic coil through the circuit board. Make the electrodes of the electromagnet the same as the electrodes of the T-shaped magnet rotating shaft. The same sex repels each other. The electromagnet pushes the T-shaped magnet rotating shaft outward. The magnet rotating shaft extends outward and is inserted into the rotating shaft socket provided on the outer wall of the spherical seed chamber. In this way, the T-shaped magnet rotating shafts on both sides hang the spherical seed chamber.

In the third step, the lifting cylinder is raised through the control of the electrical circuit. The sliding arm drives the transmission gear to contact the outer wall of the spherical seed chamber. The transmission gear meshes with the teeth provided on the annular gear path. At the same time, press the push pin on the support arm, and the push pin pushes inward against the L-shaped conduit. The L-shaped conduit slides along the chute, protrudes from the long concave hole, and then pushes open the cross opening on the elastic membrane. Make the L-shaped conduit extend into the inside of the spherical seed chamber; at this time, push the piston push rod of the coating agent container to push a certain dose of coating agent into the inside of the spherical seed chamber, and pass the capacity scale on the coating agent container. Calculate the amount of coating to be pushed in; then pull back the push pin to return the L-shaped catheter and close the cross opening on the elastic membrane, and then finish dispensing the coating agent. The structure of the push pin can also be designed to be other existing structures in the prior art that can realize the forward and backward extension of the L-shaped conduit. For example, it can be designed to push the L-shaped conduit forward when the L-shaped conduit is pressed for the first time, and then push the pin when pressing again. The structure of L-shaped catheter return.

The fourth step is to set the number of horizontal and vertical axis rotations of the spherical seed chamber. Power is supplied to the motor II through the circuit board, and the transmission gear drives the spherical seed chamber to rotate, that is, the horizontal axis rotation, and the two T-shaped magnet rotating shafts are the rotation of the horizontal axis. The counter counts the number of revolutions on the horizontal axis. The electronic counter includes a signal radiation source and a signal receiving source. When the signal is interrupted by the hanging ring, it counts once.

When the electronic counter registers the number of horizontal axis rotations, the lifting cylinder retracts the transmission gear and the motor stops rotating. At the same time, the starter motor III starts, the two sets of pulleys start, and the hook is lowered by releasing the hinge. Due to inertia, the spherical seed chamber will continue to rotate. When the hanging ring on the spherical seed chamber is hooked with the hook, the electromagnetic coil is changed through the circuit board. In the direction of current transmission, the electromagnet electrode is opposite to the electrode of the T-shaped magnet rotating shaft. Opposites attract each other. The electromagnet attracts the T-shaped magnet rotating shaft inward, and the T-shaped magnet rotating shaft withdraws inward from the rotating shaft socket. In this way, the T-shaped magnet rotating shafts on both sides release the spherical seed chamber.

The fifth step is to start the motor I to drive the turntable to rotate, and the turntable drives the spherical seed chamber under the hook to rotate vertically. Set the speed of the motor in advance, and control the rotation time of the turntable through the set number of revolutions. It will stop after the time is completed.

The sixth step is to remove the spherical seed chamber from the hook, pour out the coated seeds, and the pulley group will rotate to automatically retract the hinge and lift the hook.

Compared with the prior art, the spherical seed chamber of the present invention realizes the horizontal and vertical axis rotation of the spherical seed chamber through the combined structure of the T-shaped magnet rotating shaft of the support arm on the frame and the hook at the lower part of the turntable. , the seeds are fully coated and of high quality under different states of rotation and stirring in the seed chamber, and the conversion of these two rotation states realizes automatic control, providing a very convenient and practical package for laboratory seed coating.

At this time, the spherical seed chamber 10 is separated from the frame 21, the T-shaped magnet rotating shaft 35 of the support arm 17 is in a contracted state, and the lower part of the turntable 5 The hook 8 and the hanging ring 9 are in a separated state. Then hold the spherical seed chamber 10 with your hands so that the spherical seed chamber 10 is located between the support arms 17 on both sides.

In the second step, the electromagnetic coil 37 is energized, and the current direction of the electromagnetic coil 37 is controlled through the circuit board, so that the electrodes of the electromagnet 38 are the same as the electrodes of the T-shaped magnet rotating shaft 35, and they repel each other. The electromagnet 38 moves the T-shaped magnet rotating shaft 35 toward Pushing out, the T-shaped magnet rotating shaft 35 extends outward and is inserted into the rotating shaft socket 30 provided on the outer wall of the spherical seed chamber. In this way, the T-shaped magnet rotating shafts 35 on both sides hang the spherical seed chamber.
