DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0032] See also Figures 1-6 , which is a schematic structural diagram of the automated tray seeding device provided by the present invention.

[0033] As can be seen from the figure, the automated tray seeding device provided by the present invention includes eight components: a frame 100, a moving component 200, a seeding machine mounting bracket 300, a seeding machine 400, a rotating component 500, a tray 600, a seed trough 700, and a human-computer interaction component 800.

[0034] The frame 100 is the main structure for carrying other components. The frame 100 is provided with a bracket for placing the plug tray 600 and the seed tank 700.

[0035] The planter mounting bracket 300 is connected to the frame 100 via the moving assembly 200 and is located above the tray holes 600. The planter 400 is mounted on the planter mounting bracket 300 via the rotating assembly 500. The planter 400 on the planter mounting bracket 300 is driven by the moving assembly 200 to move above the tray holes 600 and the moving range can fully cover the tray holes 600.

[0036] The planter mounting bracket 300 is provided with a bracket for accommodating the seed trough 700 and a seed guide seat 900. The bracket and the seed guide seat 900 are both located below the planter 400. The seed guide seat 400 is located above the tray holes 600 and is provided with a plurality of guide holes 410. The plurality of guide holes 410 are distributed in the same manner as the holes on the tray holes 600. The seed guide seat 900 is used to accurately sow seeds into the holes of the tray holes 600.

[0037] The plurality of seeding needles 422 on the seeding machine 400, the plurality of slot holes on the seed slot 700, and the plurality of guide holes 910 on the seed guide seat 900 all correspond to each other;

[0038] The planter 400 can rotate based on the driving of the rotating assembly 500 and form a first position and a second position.

[0039] like Figure 3 , Figure 4 The seeder 400 in the figure is located at a first position. In the first position, several seeding needles 422 on the seeder 400 extend into the seed groove 700, and the seeder 400 can suck seeds into the seeding needles by utilizing vacuum suction.

[0040] like Figure 5 , Figure 6In the second position, several sowing needles 422 on the seeder 400 are located above the seed guide seat 900, and the seeder 400 can release the seeds in the sowing needles and fall into the guide holes in the seed guide seat 900 by turning off the vacuum suction. The seeds are guided by the guide holes 910 and fall into the holes of the hole tray 600 in sequence.

[0041] The human-machine interaction component 800 is set on the frame 100 and is used to control the moving component 200, the seed drill 400, and the rotating component 500.

[0042] Compared with the existing technology, this solution uses an automated tray seeding device, which eliminates the need for manual handheld seeding and can accurately sow seeds through automated seed suction and release.

[0043] The following example shows the sowing steps in actual application. Seed absorption is divided into three processes: positioning, probing and adsorption. The sowing process is started through the human-computer interaction component 800. First, the moving component 200 operates to drive the seeder 400 to move on the top of the hole tray 600 until the seed guide seat 900 reaches the required sowing position on the hole tray 600 and reaches the preset designated position. Secondly, the rotating component 500 installed on the frame 100 operates to drive the seeder 400 to rotate. Under its action, the sowing needle makes a downward motion and reaches the inside of the seed groove 700; finally, the seeder 400 uses the vacuum adsorption principle to complete the seed adsorption.

[0044] Seed release is a two-step process: positioning and releasing. Following the set operating procedure, after the seeds are attracted, the rotating assembly 500 drives the seeding needle to rotate directly above the seed guide seat 900. The seeder 400 then shuts off the vacuum suction, and the airflow releases the seeds from the seeding needle into the seed guide seat 900 below the seed slot 700. Gravity then forces the seeds to slide precisely into the holes in the seed tray 600.

[0045] The following is a detailed description of each component of this solution with reference to the accompanying drawings.

[0046] Specifically, the frame 100 is the supporting structure of the entire device and the installation base of various components and mechanisms. The frame 100 is preferably made of stainless steel to ensure the stability and rigidity requirements of the device operation.

[0047] The rack 100 is a rectangular frame as a whole. A rectangular through hole is formed in the middle of the rectangular rack 100 , and feet 110 are provided at the four corners of the rectangular rack 100 . The rack 100 is supported on the ground by the feet 110 .

[0048] A seed trough bracket 120 is provided on the front side of the frame 100, on which the seed trough 700 can be placed, for fixing the seed trough 700 and filling the seeds. A hole tray bracket 130 is provided at the bottom of the frame 100, on which the hole tray 600 can be placed. The hole tray 600 is arranged on the hole tray bracket 130 and can be exposed in the rectangular through hole in the middle of the frame 100. The hole tray bracket 130 is mainly used to support and fix the hole tray 600 so that the position of the hole tray 600 does not change during the sowing operation, ensuring that the seeds can be accurately sown in the hole of the hole tray

[0049] Furthermore, the moving component 200 includes equal-length synchronous belts 210 and motors 220 arranged on the left and right sides of the frame 100. The synchronous belts 210 are equipped with a tensioning mechanism 230. The motor 220 is arranged on the rear side of the frame 100 and is located between the two synchronous belts 210. The output shaft of the motor 220 is respectively connected to the driving wheels of the two synchronous belts 210. The two synchronous belts 210 can rotate synchronously through the drive of the motor 220.

[0050] Furthermore, the motor is a 220 dual-output shaft stepper motor, and the shaft end of the motor 220 is connected to the transmission rod to drive the synchronous pulley of the synchronous belt 210, thereby driving the sowing installation bracket 300 to operate.

[0051] The moving component 200 of such a structure is connected in cooperation with the planter mounting bracket 300. The two sides of the planter mounting bracket 300 are respectively connected to the synchronous belt 210 on the left and right sides of the frame 100 through sliders. Driven by the motor 220, the planter mounting bracket 300 moves linearly between the front and rear sides of the frame 100 and is located on the top of the hole tray 600.

[0052] The seeder 400 and the rotating assembly 500 are placed on the top of the seeder mounting bracket 300, and a bracket for placing the seed trough 700 and a seed guide seat 900 are provided at the bottom. The seed trough 700 is filled with seeds on the seed trough bracket 120. After filling, the seed trough 700 is moved to the bracket for adsorption by the seeder 400.

[0053] Furthermore, the seed drill 400 includes a vacuum pump 410, a seeding needle tube, and the seeding needle tube includes a vacuum tube 421 and a plurality of seeding needles 422 disposed on the vacuum tube 421 and in communication with the vacuum tube 421;

[0054] The vacuum pump 410 is connected to the vacuum tube 421 through a pipeline. By starting the vacuum pump 410, the pressure inside the vacuum tube 421 can be reduced to form a vacuum state, and the seeds can be sucked into the sowing needle 422 by vacuum suction. By turning off the vacuum pump 410, the seeds in the sowing needle 220 can be released.

[0055] The sowing machine 400 of such a structure is connected with the rotating assembly 500, and the sowing machine 400 is driven by the rotating assembly 500 to rotate, thereby completing the adsorption and release of seeds.

[0056] The rotating assembly 500 includes a rotating motor 510, a rotating shaft 520, and two rotating arms 530. The rotating motor 510 is mounted on the planter mounting bracket 300. The output shaft of the rotating motor 510 is connected to the rotating shaft 520. The rotating shaft 520 is mounted on the planter mounting bracket 300 via a bearing. One end of the two rotating arms 530 is connected to the rotating shaft 520, and the other end is connected to the vacuum tube 421.

[0057] The rotating assembly 500 of such a structure is driven by the rotating motor 510 to drive the rotating shaft 520 to rotate, thereby driving the rotating arm 530 set on the rotating shaft 520 to rotate, and the rotating arm 530 then drives the vacuum tube 421 to rotate. The vacuum tube 421 rotates and cooperates with the seed slot 700 and the seed guide seat 900 on the bracket to form the first position and the second position respectively.

[0058] like Figure 3-Figure 6 This solution does not limit the relative position setting relationship between the seed groove 700 and the seed guide seat 900, which can be determined according to actual needs. It only needs to satisfy that the rotating component 500 can drive the seeding needle 422 to extend into the seed groove 700 to form the first position through rotation and drive the seeding needle 422 to move to the top of the seed guide seat 900 to form the second position through rotation. In this solution, the seed groove 700 and the seed guide seat 900 are arranged side by side relative to each other.

[0059] Furthermore, the human-machine interaction component 800 is used for the human-machine interface and is mainly used to operate and monitor the working status of the device. It includes an interactive display 810 and a start button 820. The interactive display 810 is connected to the vacuum pump 410, the motor 220, and the rotating motor 510. It can obtain the working status of the vacuum pump 410, the motor 220, and the rotating motor 510, adjust the parameters, and can start and close the vacuum pump 410, the motor 220, and the rotating motor 510 respectively through the start button 820.

[0060] Furthermore, in order to improve the applicability of this device and to adapt to seeds of different sizes, shapes, and surface treatments, the seeding needle 422 is connected to the vacuum tube 421 in a detachable connection manner, preferably a threaded connection, so that the installation and disassembly of the seeding needle 422 are very simple, and it can be replaced by just twisting it. Different models of seeding needles 422 can be replaced according to requirements.

[0061] In order to meet the needs of hole trays 600 of different specifications and sizes, firstly, the vacuum tube 421 can be replaced through a quick-insert structure. The vacuum tube 421 and the vacuum pump 410 are preferably connected with a quick-insert connector. Vacuum tubes of different lengths and sizes can be designed, and the vacuum tubes can be punched at fixed points according to the plant spacing value to determine the number and installation position of the sowing needles 422; secondly, parameters such as hole spacing, adsorption time, and lateral movement speed can be set on the human-machine interface to meet diverse sowing needs and effectively improve the quality and efficiency of sowing operations.
