Description

Technical Field

[0001] The utility model relates to the technical field of sowing equipment, and more specifically, to a plug seedling sowing device. Background Art

[0002] Plug seedling raising is a modern substrate seedling raising method. It uses plug trays as seedling containers, specific substrates as media, and provides necessary nutrients for seedlings by adding premixed fertilizers or irrigating nutrient solutions.

[0003] During plug seedling raising, the traditional manual spot sowing is slow, inefficient, and the sowing depth is inconsistent, which is not conducive to the cultivation of strong seedlings. When the emergence rate is low, reseeding is required, resulting in uneven growth and inconsistent ages of seedlings. The mechanization of spot sowing during plug seedling raising improves the sowing rate and the sowing depth is consistent, which lays a foundation for cultivating strong seedlings with consistent growth. However, some existing automatic sowing mechanisms, such as a Chinese patent with the authorized announcement number of CN 216722034 U and the patent name of a rapid sowing device on a seedling plug tray, through the settings of a stepping motor, a feeding tray, feeding holes, and sowing holes, utilize the cooperation of the feeding tray and the feeding holes to equally divide the seeds stored in the seed storage bin into the internal feeding holes through the feeding hole, and then drive the feeding tray to rotate by the stepping motor, so as to plant the seeds divided in the feeding holes into the seedling tray through the sowing holes. Although this structural setting solves the technical problems of slow sowing speed and inconsistent sowing depth in the form of manual sowing, this structural setting cannot effectively ensure that only one seed enters the sowing hole each time, and at the same time, other auxiliary components need to be coordinated during use to form certain sowing holes and substrate coverage.

[0004] Therefore, how to provide a plug seedling sowing all-in-one machine that improves the sowing efficiency, ensures the consistency of sowing depth, and realizes the integration of sowing and substrate coverage is an urgent problem to be solved by those skilled in the art.

[0049] Control unit, the control unit controls the operation of the driving mechanism 2, the adsorption mechanism 4, and the telescopic rod 32.

[0050] In order to further optimize the above technical solution, the driving mechanism 4 is a driving motor, and the vertical rod 41 is fixed on the power output shaft of the driving motor.

[0051] To further optimize the above technical solution, first slide rails 33 and second slide rails 34 are vertically provided on both side walls of the sleeve 3.

The structural settings and working principles of the suction cup and the adsorption needles are the same as those in the prior art and can achieve adsorption and release, and will not be elaborated herein.

[0056] In order to further optimize the above technical solution, the control unit can simultaneously control the adsorption and release of the adsorption needle 422, and can also realize individual control of each adsorption needle 422; at the same time, a detection sensor is installed on the outer wall of the adsorption needle 422, which can effectively detect whether seeds are adsorbed in the adsorption needle. If it is detected that a certain adsorption needle 422 fails to adsorb seeds, the adsorption needle 422 can be individually controlled for adsorption and release to ensure that there are seeds in each sowing hole.

[0059] In order to further optimize the above technical solution, it also includes a manipulator 8. There are two manipulators 8. The two manipulators 8 are respectively installed on both sides of the frame 1.

[0060] In order to further optimize the above technical solution, the number of through holes, seed delivery tubes 51 and adsorption ends of the adsorption mechanism 4 are multiple, the number is the same, and they correspond one to one.

[0061] In order to further optimize the above technical solution, the aperture of the through hole and the outer diameter of the seed delivery tube 51 can be adjusted as needed. It is necessary to ensure that the inner diameter of the seed delivery tube 51 is larger than the adsorption needle 411 to ensure that the seeds can smoothly enter the seed delivery tube 51 and enter the sowing hole through the conical structure at the bottom of the seed delivery tube 51; at the same time, it is also necessary to ensure that the opening size of the conical structure at the bottom of the seed delivery tube 51 is sufficient to ensure that the seeds enter the sowing hole.

[0062] In order to further optimize the above technical solution, the number of through holes, seed delivery tubes 51, and adsorption needles 422 can be the same as the specifications of the hole tray 9, so as to complete the sowing of all the holes in the hole tray 9 at one time; at the same time, the number of through holes, seed delivery tubes 51, and adsorption needles 422 can be adjusted with the number of holes in the hole tray 9.

[0063] The implementation process of this utility model is:

[0064] Put the substrate evenly into the seedling tray 9, and place the seedling tray 9 on the rack 1. In the initial state, the sowing tray 5 is located above the seedling tray 9. The control unit controls the manipulator 8 to drive the rectangular frame 412 to move directly above the seed storage box 7. By controlling the control unit to pump air out of the suction cup 421, a negative pressure is formed inside the adsorption needle 422, and the adsorption needle 422 adsorbs the seeds in the seed storage box 7 (the adsorption needle 422 can only adsorb one seed each time). Then, control the manipulator 8 to drive the rectangular frame 412 to move directly above the sowing tray 5. By controlling the control unit to lower the first slider 35, the conical structure at the lower end of the seed delivery pipe 51 is inserted into the substrate in the seedling tray 9 to form a sowing hole. Then, control the suction cup 421 to exhaust air, so that the seeds on the adsorption needle 422 enter the sowing hole through the seed delivery pipe 51. At this time, control the manipulator 8 to drive the rectangular frame 412 to be located above the seed storage box 7 again to prepare for sowing the next seedling tray 9. At the same time, control the first slider 35 to rise to a certain height, then control the driving mechanism 2 to rotate, drive the telescopic rod 32 to be located directly above the seedling tray 9, control the second slider 36 to descend to an appropriate position, and control the telescopic end of the telescopic rod 32 to drive the soil covering plate 6 to reciprocate to cover the sowing hole. After the covering is completed, through the grasping mechanism, the completed seedling tray 9 is transported to the next process (the grasping mechanism can be a manipulator or other grasping components. At this time, the settings of each structure do not interfere with the grasping of the seedling tray 9 that has completed sowing and substrate covering by the grasping mechanism); then control the driving mechanism 2 to rotate in the reverse direction, so that the sowing tray 5 is located directly above the seedling tray 9 to sow the next seedling tray 9.

Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
