Description

Technical Field

[0001] The invention relates to the technical field of forest seed sowing, and in particular to a sowing device for forest planting. Background Art

[0002] In the process of tree sowing, for large seeds such as walnuts and ginkgo, spot sowing is generally adopted. The spacing between rows and plants of spot sowing should be determined according to the characteristics of the tree species and the cultivation years of the seedlings. In the process of sowing, in order to ensure the germination rate and survival rate of the seeds, it is necessary to bury the seeds in the sowing pits, and then fill the loose soil back into the sowing pits. At the same time, for trees with larger particles, deeper sowing pits need to be dug during the sowing process to facilitate the rooting depth of the subsequent seeds after germination, to prevent the shallow roots of the trees after they grow up, resulting in poor wind resistance of the trees and causing the problem of toppling over in the early stage of growth. At present, the method of sowing is adopted. During the sowing process, traditional seed drills directly sow seeds into the soil with a shallow sowing depth. At the same time, they are unable to automatically dig sowing holes and loosen the soil around the seeds, resulting in a low germination rate of tree seeds. At the same time, in the subsequent production process, the rooting depth is shallow, resulting in a high subsequent mortality rate of trees. Currently, manual sowing holes are mostly dug, followed by sowing, and then the excavated soil is loosened and backfilled to ensure a high survival rate of tree seeds. However, this sowing method is inefficient and is not conducive to large-scale sowing of trees. Therefore, a sowing device for tree planting is proposed. Summary of the invention

The outer surface of the first gear 33 is meshingly connected to a second gear 34 fixedly sleeved on the transmission tube 6.

[0040] The motor 31 drives the first rotating shaft 32 to rotate, and the first rotating shaft 32 drives the transmission tube 6 to rotate through the first gear 33 and the second gear 34 .

[0043] The seeds are quantitatively put into the feeding tube 2 through the feeding mechanism, and the opening and closing mechanism in the feeding tube 2 is opened at this time, and then the seeds enter the transmission tube 6 through the feeding tube 2, and the opening and closing mechanism on the transmission tube 6 is closed at this time, and then the first electric telescopic rod 4 drives the mounting plate 5 to move downward, and the mounting plate 5 drives the transmission tube 6 to move downward, and the first transmission mechanism drives the transmission tube 6 to rotate, and the transmission tube 6 drives the crushing knife 14 at the bottom to crush the soil to loosen the soil, and at the same time, the transmission tube 6 drives the transmission screw rod 13 to rotate, and the transmission screw rod 13 lifts the crushed loose soil from the circle tube 12 upward, and at the same time, the loose soil The driving screw 13 is used to stir and lift the material to make the soil looser. At this time, the broken soil enters the circle tube 12. After that, when the driving tube reaches the sowing depth, the first electric telescopic rod 4 no longer drives the mounting plate 5 to move downward, and then the opening and closing mechanism on the driving tube 6 is opened, and then the seeds fall from the driving tube 6 into the excavated pit, and then the water pump 42 works.

At the same time, the first electric telescopic rod 4 drives the mounting plate 5 to move downward The loose soil after excavation is automatically backfilled into the sowing pit, and the loose soil is convenient for the seeds to germinate and grow. Then, when the soil is completely backfilled, the water pump supplies water again to the transmission pipe 6. At this time, the water is scattered into the top of the sowing pit through the transmission pipe 6 to water the loose soil in the sowing pit, thereby achieving full moistening of the soil in the sowing pit, which is convenient for the subsequent germination of the seeds, thereby realizing automatic digging, loosening, sowing, watering and soil backfilling integrated sowing for forest seeds, which greatly improves the sowing effect and sowing efficiency of seeds, and also improves the survival rate of seeds after sowing.
