Description

Technical Field

[0001] The invention relates to the technical field of fertilization, in particular to fertilization equipment and a fertilization method for cultivating forest seedlings. Background Art

[0002] In the process of forest seedling cultivation, fertilization is the key link to improve the growth quality and yield of seedlings. There are many methods of fertilizing seedlings, mainly including radial ditch fertilization, ring ditch fertilization, cave fertilization and strip ditch fertilization. These methods have their own characteristics and are suitable for different seedling growth stages and soil conditions. In contrast, the cave fertilization method has been widely used in seedling fertilization due to its unique advantages. The cave fertilization method is to dig a certain number of holes near the roots of the seedlings, sprinkle fertilizer into the holes, and then cover the soil. This method is not easy to damage the roots of the seedlings. The fertilizer has a relatively good quick-acting effect after use, which can reduce the fixed loss of fertilizer in the soil and is also conducive to better decomposition by microorganisms. The cave fertilization method can ensure that the fertilizer is accurately applied near the roots of the seedlings, improve the utilization rate of fertilizer, and promote the growth of seedlings. However, there are some disadvantages in the existing technology of using cave fertilization method to fertilize seedlings. The most significant problem is that it is necessary to manually dig holes and then spread fertilizer into the holes. This step is not only time-consuming and labor-intensive, increasing labor costs, but also the depth of the manually dug holes is difficult to ensure consistency, resulting in uneven fertilizer distribution, affecting the fertilization effect.

[0021] A fertilization method of a fertilization device for cultivating forest seedlings, specifically comprising the following steps: Step 1: Plan the location and depth of the cave where the fertilizer needs to be fertilized along the four sides of the seedlings, rotate the screw 22, and the rotational force generated by the rotation of the screw 22 will drive the blocking plate 23 to move downward. The moving position of the blocking plate 23 is read through the scale line 19 until the blocking plate 23 is moved to a suitable distance from the top of the support leg 20, and the fertilizer is poured into the inner cavity of the storage chamber 10. The fertilizer poured into the inner cavity of the storage chamber 10 will fall into the inner cavity of the two material pipes 817 through the discharge port 11, and the inner cavity of the material pipe 817 is blocked by the plug 816 to prevent the fertilizer from continuing to fall. The housing 1 can be taken and moved by taking the two handles 15 with both hands; Step 2, move the housing 1 to the place where holes need to be drilled and fertilized, place the soil-breaking cone 93 above the target location, and make the bottom end of the leg 20 contact the ground, start the motor 94, and use the output end of the motor 94 to drive the gear 96 to rotate through the connecting rod 95. The rotation of the gear 96 mobilizes the gear ring 92 to rotate. The rotation of the gear ring 92 will drive the three soil-breaking cones 93 to move circumferentially, so as to use the soil-breaking cones 93 that move circumferentially to loosen the soil and dig holes. At the same time, press down the handle 15 with both hands, and the pressing down of the handle 15 drives the handle 13 and the positioning rod 17 to press down, and the positioning rod 17 moves downward. The outer shell 1 is driven downward by the positioning hole 6, and the ground-breaking cone 93 gradually digs a hole in the ground with the circumferential movement, thereby prompting the outer shell 1 to drive the ground-breaking cone 93, the first barrel 84 and the second barrel 85 to move downward. The downward movement of the outer shell 1 prompts the support leg 20 to move upward along the inner cavity of the blocking groove 2, and squeezes the second spring 21 to undergo elastic deformation until the top of the support leg 20 contacts the bottom of the blocking plate 23, so that the outer shell 1 can no longer drive the ground-breaking cone 93, the first barrel 84 and the second barrel 85 to move downward, indicating that the ground-breaking cone 93 has drilled into the set depth underground. Step 3, pull the handle sleeve 15 outward, so that the handle sleeve 15 drives the positioning rod 17 to move outward, and stretches the first spring 18 to cause elastic deformation, until the positioning rod 17 moves out of the inner cavity of the positioning hole 6. At this time, continue to press the handle sleeve 15 downward to prompt the handle 13 to move downward along the inner cavity of the slide groove 5. The handle 13 moves downward and drives the push rod 812 to move downward through the connecting frame 820. The push rod 812 moves downward and drives the lower pressing frame 810 to move downward, and stretches the third spring 813 to cause elastic deformation. The lower pressing frame 810 moves downward and drives the collar 87 and the push plate 814 to move downward. The push plate 814 moves downward and drives the plug 816 to move downward through the connecting plate 815 until the plug 816 moves downward to the bottom of the feed chute 818. At this time, the plug 816 releases the blockage of the feed pipe 817, so that the fertilizer in the inner cavity of the feed pipe 817 falls to the lower through the top of the plug 816. The fertilizer is then fed into the inner cavity of the material trough 818 and falls into the inner cavity of the first material barrel 84 and the second material barrel 85 through the lower material trough 818. The downward movement of the ring 87 will prompt the roller 89 to roll downward along the inner cavity of the rolling groove 86, and under the driving force of the lower pressure frame 810, the top ends of the two groups of first tilting rods 82 and second tilting rods 83 are gradually separated, and the top ends of the first tilting rods 82 and the second tilting rods 83 are gradually separated. With the support rod 81 as the center of the circle, the bottom ends of the first tilting rods 82 and the second tilting rods 83 drive the bottom ends of the first material barrel 84 and the second material barrel 85 to gradually separate, so that the fertilizer in the inner cavity of the first material barrel 84 and the second material barrel 85 will fall into the hole. After an appropriate amount of fertilizer is added to the hole, the handle 15 is driven to move upward, thereby moving in the opposite direction to the above, and the hole drilling and fertilization at the current position can be completed. Repeating the above actions can realize fertilization of the planned positions around the seedlings.

[0022] To sum up, this device simplifies the operating process of the cave fertilization method, eliminates the need for manual digging, reduces labor intensity and labor costs, and at the same time ensures the uniformity of the hole depth and position, so that fertilizer can be accurately and evenly distributed near the root system of seedlings, thereby improving the utilization rate of fertilizers and fertilization effects, further promoting the healthy growth of seedlings, and improving the overall efficiency and quality of forest seedling cultivation.

The fertilization method of the fertilization equipment for forest seedling cultivation according to claim 7, characterized in that: The specific steps include: Step 1: Plan the location and depth of the cave where the fertilizer needs to be applied along the periphery of the seedlings, rotate the screw (22), and the rotational force generated by the rotation of the screw (22) will drive the blocking plate (23) to move downward, and read the moving position of the blocking plate (23) through the scale line (19) until the blocking plate (23) is moved to a suitable distance from the top of the support leg (20), and pour the fertilizer into the inner cavity of the storage cavity (10). The fertilizer poured into the inner cavity of the storage cavity (10) will fall into the inner cavity of the two material pipes (817) through the discharge port (11), and the inner cavity of the material pipe (817) is blocked by the plug (816) to prevent the fertilizer from falling further, and the outer shell (1) can be taken by holding the two handles (15) with both hands to move; Step 2: Move the housing (1) to the place where a hole needs to be drilled and fertilized, place the soil-breaking cone (93) above the target location, and make the bottom end of the support leg (20) contact the ground, start the motor (94), and use the output end of the motor (94) to drive the gear (96) to rotate through the connecting rod (95). The gear (96) rotates to mobilize the gear ring (92) to rotate. The rotation of the gear ring (92) drives the three soil-breaking cones (93) to move in a circumferential direction, so as to use the soil-breaking cones (93) that move in a circumferential direction to loosen the soil and dig a hole. At the same time, press down the handle sleeve (15) with both hands. Pressing down the handle sleeve (15) drives the handle (13) and the positioning rod (17) to move downward. The positioning rod (17) is pressed downward. The outer shell (1) is driven to move downward through the positioning hole (6), and the ground-breaking cone (93) gradually digs a hole in the ground as it moves in a circumferential direction, thereby causing the outer shell (1) to drive the ground-breaking cone (93), the first barrel (84) and the second barrel (85) to move downward. The downward movement of the outer shell (1) causes the support leg (20) to move upward along the inner cavity of the blocking groove (2) and squeeze the second spring (21) to undergo elastic deformation until the top end of the support leg (20) contacts the bottom end of the blocking plate (23), so that the outer shell (1) can no longer drive the ground-breaking cone (93), the first barrel (84) and the second barrel (85) to move downward, indicating that the ground-breaking cone (93) has drilled into the ground to a set depth. Step 3: Pull the handle cover (15) outward, so that the handle cover (15) drives the positioning rod (17) to move outward, and stretches the first spring (18) to cause elastic deformation, until the positioning rod (17) moves out of the inner cavity of the positioning hole (6). At this time, continue to press the handle cover (15) downward to cause the handle (13) to move downward along the inner cavity of the slide groove (5). The handle (13) moves downward through the connecting frame (820) to drive the push rod (812) to move downward. The push rod (812) moves downward to push the pressing frame ( The lower pressure frame (810) moves downward and stretches the third spring (813) to undergo elastic deformation. The lower pressure frame (810) moves downward, driving the collar (87) and the push plate (814) to move downward. The push plate (814) moves downward, driving the plug (816) to move downward through the connecting plate (815), until the plug (816) moves downward to below the feed chute (818). At this time, the plug (816) releases the blockage of the feed pipe (817), so that the fertilizer in the inner cavity of the feed pipe (817) passes through the plug (816). The top of the first tilting rod (82) and the top of the second tilting rod (83) fall into the inner cavity of the lower material trough (818), and then fall into the inner cavity of the first barrel (84) and the second barrel (85) through the lower material trough (818). The downward movement of the collar (87) causes the roller (89) to roll downward along the inner cavity of the rolling groove (86), and under the driving force of the lower pressing frame (810), the tops of the two groups of first tilting rods (82) and second tilting rods (83) are gradually separated. The tops of the first tilting rod (82) and the second tilting rod (83) are gradually separated, with the support rod (81) as the support rod. The center of the circle causes the bottom ends of the first tilting rod (82) and the second tilting rod (83) to drive the bottom ends of the first barrel (84) and the bottom ends of the second barrel (85) to gradually separate, so that the fertilizer in the inner cavities of the first barrel (84) and the second barrel (85) will fall into the hole, until an appropriate amount of fertilizer is added to the hole, driving the handle (15) to move upward, thereby performing a movement in the opposite direction to the above, and completing the hole drilling and fertilization at the current position. Repeating the above actions can achieve fertilization at the planned positions around the seedlings.
