[0002] The forestry nursery seeder is a mechanical equipment specially designed for seeding operations in forestry nurseries. It realizes mechanized and efficient seeding operations by evenly and quantitatively sowing forest seeds on the seedbed.

[0003] When using a seeder body to sow seeds in the forestry production process, traditional seeders often use fixed sowing depths and forces, which are difficult to adapt to soils of different hardness. In soils with higher hardness, the seeder may be damaged due to excessive resistance, while in soils with lower hardness, it may cause sowing too deep or too shallow, affecting seed germination and reducing seed survival rate. At the same time, it also makes the traditional seeder body less applicable and inconvenient to use. Summary of the invention

At the same time, it also causes the traditional seeder body to have low applicability and be inconvenient to use.

When the sowing roller rotates and drives the seeds in the sowing groove to move to a certain position along the inner wall of the circular ring frame, the soil will be loosened by the loosening device and diverted to be planted in the soil, and then the irrigation device will be used for irrigation.

[0017] Preferably, the inner walls of the several outlets of the water spray rack are fixedly connected with filter screens.

[0018] The effect achieved by the above components is: by setting up a filter net, the inner wall of the outlet of the water spray frame can be protected, so that when drilling soil for sowing, soil is not easily splashed into the inner wall of the water spray frame, thereby avoiding blockage at the outlet of the water spray frame and improving its service life.

[0019] Preferably, outer surfaces at both ends of the water spray frame are fixedly connected with round hole frames, and one side of the round hole frame is fixedly connected to one side of the seeder body.

[0047] Reference Figure 1-11As shown, this embodiment discloses that the auxiliary device 4 includes a scraper 41 and a pad 46, one side of the scraper 41 is fixedly connected to a threaded rod 42, the outer surface of the threaded rod 42 is threadedly connected to a screw hole block 43, one side of the seeder body 1 is provided with a rectangular groove 44, and one side of the inner wall of the rectangular groove 44 is provided with a rectangular hole 45, and the scraper 41 and the threaded rod 42 are slidably connected to the rectangular groove 44 and the rectangular hole 45 respectively. After placing the seeder body 1 into the sowing field, the scraper 41 and the threaded rod 42 can be manually slid down to a certain position in the rectangular groove 44 and the rectangular hole 45 respectively according to the height of the seeder and the ground, and then the screw hole block 43 is turned to rotate it to a certain position so that one side of it abuts against one side of the seeder body 1, and the scraper 41 is fixed to the limit column. After the sowing of seeds is completed with the cooperation of the seeder body 1 and the loosening device 2, the scraper 41 will move with the movement during the driving of the seeder body 1 to scrape and flatten the drilled soil, so that the sown seeds can be covered, the sowing efficiency is improved, and the use of the seeder body 1 is convenient.

[0048] Reference Figure 1-11 As shown, this embodiment discloses that a pad 46 is sleeved on the outer surface of the threaded rod 42, and the pad 46 is arranged between the screw hole block 43 and one side of the planter body 1. By arranging the pad 46, the contact area between the screw hole block 43 and the planter body 1 can be increased, so that the scraper 41 is fixed more firmly.

[0049] The working principle is as follows: when the seeder body 1 is used to sow seeds in the forestry production process, before using the seeder body 1, first unscrew the box cover 32, inject water into the water tank 31, and then cover the box cover 32. At the same time, according to the height of the seeder and the ground, the scraper 41 and the threaded rod 42 can be manually slid down to a certain position in the rectangular groove 44 and the rectangular hole 45 respectively, and then the screw hole block 43 is screwed to rotate it to a certain position so that one side of it abuts against one side of the seeder body 1, and the scraper 41 is fixed to the limiting column so that the bottom of the scraper 41 abuts against the ground. When sowing, the seeds will be put into the feed hopper 7, and then the seeds will fall into the sowing groove 11 on the sowing roller 8 through the outlet of the feed hopper 7. At this time, the drive motor 9 is started to drive the sowing The seed roller 8 rotates in the inner wall of the seeder body 1 and the circular frame 6. At the same time, the operator holds the push rod 5 to push the seeder body 1 to travel in the planting field. The outer surface of the seed roller 8 is tightly attached to the inner wall of the circular frame 6. Therefore, the number of seed particles falling into the seeding groove 11 is fixed. When the seeding roller 8 rotates to drive the seeds in the seeding groove 11 to move to a certain position along the inner wall of the circular frame 6, the seeds will fall into the guide tube 21, and then enter between the round rod 26 and the two drill blocks 213 along the guide tube 21. At this time, the dual-axis motor 216 on the fixed frame 217 is started to drive the first gear 218 to rotate, so that one of the gear ring blocks 28 can be driven to rotate in the inner wall of the bracket 215 and the outer surface of the round rod 26, and drive the circular ring block 27 , two U-shaped blocks 210, two rotating blocks 211 and two drill blocks 213 rotate, and then under the transmission of the second belt 214, several pairs of drill blocks 213 can be driven to rotate, and at the same time, under the connection of the second telescopic rod 225, the groove ring frame 22, the winding roller 23 and the pull rope 25 are driven to rotate. At this time, the other output end of the dual-axis motor 216 is started at the same time to drive the first telescopic rod 219 and the second gear 220 to rotate on the circular frame 6, and drive the two third gears 221 to rotate in the same direction on the outer surface of the circular frame 6. Then, under the transmission of the third belt 222, the two reciprocating screw rods 223 can be driven to rotate on the circular frame 6, so that the bracket 215 passes through the sliding hole 224 and moves downward on the reciprocating screw rod 223. The drill block 213 and the annular block 27 move downward on the outer surface of the guide tube 21 through the round rod 26. The drill block 213 and the annular block 27 not only move downward but also rotate to loosen the soil in the sowing field and drill the harder soil to make it softer. When the drill block 213, the annular block 27 and the round rod 26 move downward, the first telescopic rod 219 and the second telescopic rod 225 are pulled apart, and at the same time, one end of the pull rope 25 is continuously unwound on the winding roller 23, so that the first torsion spring 24 is deformed. When the pull rope 25 is unwound to a certain position, the other end pulls one end of the drill block 213 to rotate in the inner wall of the U-shaped block 210 with the help of the rotating block 211, driving the second torsion spring 212 to deform.The other end is opened to sow the seeds inside into the drilled soil. When the reciprocating screw rod 223 drives the bracket 215 to move upward, the drill block 213 is reset and closed under the reset action of the second torsion spring 212. At the same time, the first torsion spring 24 drives the winding rod to reset and rewind one end of the pull rope 25, so as to facilitate the next sowing operation. By doing so, the hardness of the sowing soil can be reduced, so that the sowing machine body 1 can adapt to different planting environments, improve the adaptability of use, and ensure that the planting depth of each seed is consistent, so as to improve the efficiency of seed survival. At this time, the water pump 33 is started again to pump the water in the water tank 31 into the inside of the water spraying frame 34, and then discharged from a number of water outlets, so as to irrigate the seeds just sown, provide them with water, promote seed germination, and improve the survival rate of seeds. When the sowing machine body 1 and the loosening device 2 cooperate to sow the seeds, the scraper 41 will follow the movement during the driving process of the sowing machine body 1, and the drilled soil will be scraped flat, so that the sown seeds can be covered, sowing efficiency can be improved, and the sowing machine body 1 can be used conveniently. ,
