[0021] In forestry seedling cultivation, traditional loosening devices cut the soil through a rigid structure, leaving a large number of unbroken small soil blocks after the operation, which hinders the seeds from fully contacting the soil, reduces the germination rate, and restricts the extension of the root system, affecting the growth of crops. In addition, traditional loosening devices have limited ability to break up the soil, making it difficult to form a uniform loose structure, resulting in poor soil aeration, uneven distribution of oxygen and water, and unfavorable for the respiration of tree roots and nutrient absorption. Lumpy soil needs to be broken up manually, which increases labor intensity, reduces work efficiency, prolongs the seedling cultivation cycle, and pushes up labor costs.

[0024] Such as Figure 9 As shown, a feed hole 2 is opened at the top of the vehicle frame 1. A protective cover 21 is fixedly connected to the top of the vehicle frame 1. The feed hole 2 is located below the protective cover 21. A bin door 33 is detachably installed on the outer wall of the protective cover 21.

The rotation of the blanking cylinder 24 is linked with the crushing roller 16 to ensure that the fertilizer is immediately applied after the soil is crushed, improving the utilization rate of the fertilizer; The design of the pushing plates 32 utilizes the gravity of the counterweight blocks 31 to realize the automatic pushing out of the fertilizer.

[0027] As Figure 6 and Figure 7 shown in the figure, a crushing roller 16 is rotatably connected to the inner wall of the vehicle frame 1. First synchronous wheels 19 are fixedly connected to the ends of the shafts of the crushing roller 16 and the rotating shaft 23 respectively. The two first synchronous wheels 19 are connected by a synchronous belt. A second machine base 17 is fixedly connected to the outer wall of the vehicle frame 1. A second motor 18 is fixedly connected to the outer wall of the second machine base 17. The output end of the second motor 18 is fixedly connected to the shaft end of the crushing roller 16; The setting of the crushing roller 16 further crushes and divides the soil, especially suitable for treating compacted soil or soil containing large soil clods, which helps to improve the soil structure and facilitate the growth of tree roots.

[0028] As Figure 7 and Figure 8 shown in the figure, second synchronous wheels 20 are fixedly connected to the ends of the shafts of the crushing roller 16 and the drive shaft 37 respectively. The two second synchronous wheels 20 are connected by a synchronous belt.

[0029] As Figure 14 shown in the figure, a fixing plate 42 is fixedly connected to the outer wall of the vehicle frame 1. A scraping plate 43 is arranged below the fixing plate 42. Two sliding rods 44 are fixedly connected to the top of the scraping plate 43. The ends of the sliding rods 44 penetrate through the fixing plate 42 and are slidably connected to it. An adjusting screw 45 is threadedly connected to the top of the fixing plate 42. The end of the adjusting screw 45 is rotatably connected to the scraping plate 43.

[0030] As Figure 1 and Figure 4 shown in the figure, a connection hole 3 is formed in the top of the vehicle frame 1. Mounting arms 46 are fixedly connected to both sides of the vehicle frame 1. Two support plates 4 are fixedly connected to the top of the vehicle frame 1. Swing arms 7 are rotatably connected to the outer walls of the two support plates 4. A first machine base 5 is fixedly connected to the outer wall of one of the support plates 4. A first motor 6 is fixedly connected to the top of the first machine base 5. The output end of the first motor 6 is fixedly connected to the swing arm 7.

[0031] As Figure 4 and Figure 5 shown, the device further includes a connecting arm 8. The connecting arm 8 is rotatably connected to the swing arm 7. The end of the connecting arm 8 penetrates through the connecting hole 3 and extends below the vehicle frame 1. A mounting plate 9 is fixedly connected to the end of the connecting arm 8. A plurality of harrow pins 10 are fixedly connected to the outer wall of the mounting plate 9. Connecting rods 11 are fixedly connected between adjacent two harrow pins 10. Support arms 14 are rotatably connected to the inner wall of the connecting arm 8. The end of the support arm 14 is rotatably connected to a bracket 15. The bracket 15 is fixedly connected to the vehicle frame 1. A groove 12 is formed outside the harrow pin 10. One corner of the inner wall of the groove 12 close to the arc groove 13 is a right angle. An arc groove 13 is formed at the tip of the harrow pin 10. By rotating the harrow pin 10 and inserting it into the soil, not only can the soil be effectively loosened, but also when encountering a stone, with the arc groove 13 design at the tip of the harrow pin 10, the stone can be lifted up, facilitating the continuous penetration of the harrow pin 10 into the soil. This reduces the obstruction of the stone to the soil loosening process, improves the soil loosening efficiency, and at the same time can pick out the stone from the soil.

[0032] Working principle: The vehicle frame 1 is installed on the agricultural vehicle through the mounting arm 46. The vehicle frame 1 is driven by the agricultural vehicle to move. The first motor 6 drives the swing arm 7 to rotate. The swing arm 7 drives the connecting arm 8 to rotate reciprocally. During the rotation of the connecting arm 8, the support arm 14 limits and supports the connecting arm 8. At this time, the harrow pin 10 can be inserted obliquely into the soil and lift the soil. When the harrow pin 10 is inserted into the soil, its tip contacts the stone. When the stone cannot be broken, the arc groove 13 at the tip can exert pressure on the stone, causing the stone to lift up, and then enabling the tip of the harrow pin 10 to smoothly insert into the soil below the stone. When the harrow pin 10 is pulled out of the soil, at this time the groove 12 can hook out the stone from the soil; Fertilizer is put into the inside of the storage box 22. The second motor 18 drives the crushing roller 16 to rotate. The soil lifted up is crushed and divided into pieces by the crushing roller 16. The crushing roller 16 drives the feeding cylinder 24 to rotate through the first synchronous pulley 19. At this time, the fertilizer enters the material groove 25. When the feeding cylinder 24 rotates, it drives the support rod 29 to rotate. When the feeding cylinder 24 drives the fertilizer to rotate below the storage box 22, under the action of the gravity of the counterweight 31, the sliding sleeve 30 drives the outer wall of the support rod 29 to slide towards its end. The sliding sleeve 30 drives the push plate 32 to slide outward along the inner wall of the material groove 25, so as to be able to push out the fertilizer inside the material groove 25, enabling the fertilizer to be fully mixed with the soil. When the material groove 25 rotates to the inside of the storage box 22, at this time the counterweight 31 drives the push plate 32 to slide to the bottom of the inner wall of the material groove 25 through the sliding sleeve 30, reserving space for the entry of the fertilizer; When the crushing roller 16 rotates, it drives the drive shaft 37 to rotate through the second synchronous wheel 20. The drive shaft 37 drives the extension shaft 39 to rotate through the first bevel gear 40 and the second bevel gear 401. The extension shaft 39 drives the output shaft 38 to rotate, and the output shaft 38 drives the crushing blade group 41 to rotate. During the movement of the partition plate 35, the soil is segmented to form different planting areas. After the soil enters between two adjacent partition plates 35, it is successively crushed by a plurality of crushing blades with increasing diameters, which can fully and quickly crush the soil and loosen the soil. By rotating the adjusting screw 45, the scraper 43 is driven to move, thereby adjusting the height of the scraper 43. The scraper 43 is limited by the locking nut on the adjusting screw 45. When the frame 1 moves, it drives the scraper 43 to move, and the top of the soil is leveled by the scraper 43, making the ground more flat after planting.
