Description

Technical Field

[0001] The invention relates to the technical field of sowing equipment, and in particular to a precision sowing device for small-grain seeds of Chinese herbal medicine. Background Art

[0002] Plug tray seedling technology is a modern seedling technology that uses peat, vermiculite and other light soil-free materials as seedling substrate, mechanized precision sowing, one seed per hole, and one-time seedling. Plug tray seedling is a new seedling technology that emerged in Europe and the United States in the 1970s. It has become the main method of specialized commercial seedling production in many countries.

[0003] Some tray seeders on the market now have a problem that after long-term operation, when the seed suction needle is inserted into the culture soil of the tray, the seed suction needle will be contaminated with culture soil particles, causing a gap between the seed suction needle and the seeds when the seed suction needle absorbs the seeds, thereby causing seed leakage; The seed suction needle can only absorb a single seed, and the seed germination rate is not 100%, which affects the efficiency of seed cultivation; The seeds are placed at the front end of the seed suction needle. During the sowing process, when the seeds are inserted into the culture soil through the seed suction needle, the seeds are squeezed and rubbed against the culture soil, which can easily cause seed damage.

[0004] Therefore, we made improvements on this and proposed a precision sowing device for small-grain seeds of Chinese herbal medicine. Summary of the invention

[0019] A mounting plate 6 is fixedly provided on the upper part of one end of the workbench 1, a seed silo 7 is symmetrically fixedly provided on the upper part of the mounting plate 6, and a plurality of evenly laterally arranged sowing components 9 are connected to the lower part of the seed silo 7 through a telescopic hose 8; The sowing component 9 is arranged on the upper part of the conveyor belt 4 by moving up and down through the sliding plate 10, and a hydraulic cylinder 11 is fixedly arranged on the upper middle end of the mounting plate 6, and the piston rod of the hydraulic cylinder 11 is fixedly connected to the sliding plate 10; A slide plate 12 is provided on the upper parts of the oppositely disposed side walls of the two fixed plates 2 , and both ends of the sliding plate 10 are slidably disposed in the slide grooves of the slide plate 12 .

[0020] The sowing component 9 includes a sleeve 13, an insertion tube 14 and a sowing rod 15. The sleeve 13 is connected to the lower part of the seed silo 7 through a pipeline. The front end of the insertion tube 14 is slidably arranged in the inner cavity of the end of the sleeve 13. The sowing rod 15 is arranged in the inner cavity of the sleeve 13 and the insertion tube 14. The front end of the insertion tube 14 is fixedly connected to the inner wall of the front end of the sleeve 13 through a plurality of evenly arranged connecting plates 16. A fixing ring A17 is fixedly sleeved at the lower part of the outer wall of the sleeve 13, a fixing ring B18 is fixedly sleeved at the lower part of the outer wall of the insertion tube 14, and spring rods 19 are symmetrically arranged between the fixing rings A17 and B18.

[0021] The sowing groove 20 is symmetrically arranged at the lower part of the sowing rod 15 . A fixing ring C21 is fixedly arranged at the middle part of the sowing groove 20 at the lower part of the sowing rod 15 .

[0022] The lower part of the fixing ring C21 is symmetrically provided with a spring pick 22 , and the outer wall of the spring pick 22 is elastically fitted with the inner wall of the insertion tube 14 .

[0023] The spring pick 22 is a V-shaped structure, and the top of the spring pick 22 is elastically fitted to the inner wall of the insertion tube 14 .

[0024] The upper portion of the insert tube 14 is provided with a tapered groove 23 , and the tapered groove 23 is arranged in the inner cavity of the sleeve 13 .

[0025] The two sides of the conveyor belt 4 are symmetrically and fixedly provided with rubber baffles A24, and the middle part of the conveyor belt 4 is symmetrically provided with rubber baffles B25.

[0026] Working principle of the present invention: The plug tray is placed on the conveyor belt 4. The rubber baffles A24 and B25 on both sides of the conveyor belt 4 can fix the plug tray; The stepper motor 5 drives the conveyor belt 4 to rotate through the roller 3, thereby driving the hole tray to move; Small seeds of black bilberry are placed in the seed silo 7. When the plug tray moves to the lower part of the sowing component 9, the hydraulic cylinder 11 drives the sliding plate 10 to move downward, and the fixing ring B18 of the sowing component 9 moves to the culture soil of the plug tray. The hydraulic cylinder 11 continues to drive the sowing component 9 to move downward, the fixing ring B18 abuts against the culture soil of the plug tray, and the end of the sowing rod 15 is separated from the inner cavity of the insertion tube 14 and enters the culture soil; The small seeds of black bilberry enter the sowing component 9 from the seed silo 7 through the telescopic hose 8, and enter the inner cavity of the sleeve 13 and the insert pipe 14 through the gaps between the multiple evenly arranged connecting plates 16, and then enter the sowing groove 20 from the upper part of the sowing groove 20; When the sowing rod 15 is separated from the inner cavity of the insert tube 14, the spring paddle 22 is separated from the inner cavity of the insert tube 14 at the same time, and because the spring paddle 22 is elastically fitted with the inner wall of the insert tube 14, the spring paddle 22 pushes the culture soil away, thereby allowing the small black bilberry seeds to smoothly enter the culture soil from the sowing groove 20; After sowing is completed, the hydraulic cylinder 11 drives the sliding plate 10 to rise, the sowing rod 15 retreats into the insertion tube 14, the fixing ring B18 is separated from the culture soil of the plug tray, and the stepper motor 5 drives the conveyor belt 4 to rotate through the roller 3, thereby driving the plug tray to move in preparation for the next sowing.
