Technical Field

[0001] This application relates to the field of fertilizer applicator technology, and more particularly to a fertilizer applicator for ginkgo cultivation. Background Technology

[0002] Ginkgo, belonging to the Ginkgoaceae family, is a deciduous tree. Fertilization is necessary during ginkgo cultivation. One method is hole application, which involves digging holes around the trunk to apply fertilizer, then filling the holes with soil. Fast-acting fertilizers are suitable.

[0003] A search revealed a Chinese patent with publication number CN2423706Y that discloses a fertilizer applicator. This applicator allows for precise control of the depth and amount of fertilizer application via manual operation, saving time and effort. It is simple to operate and convenient to use. However, in this device, the fertilizer pit is formed by pressing down the handle rod. After fertilization, it is not convenient to fill the pit with soil. Exposed fertilizer will reduce its effectiveness due to factors such as volatilization, rainwater, or mineralization, thus affecting the growth of ginkgo trees. Therefore, a fertilizer applicator for ginkgo planting is proposed to solve the above problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-5 This utility model provides a fertilization tool for ginkgo planting, which is used to fertilize ginkgo trees during planting and has the effect of quickly filling holes. Technical solution:

[0026] A fertilization tool for ginkgo planting includes a hollow cylindrical shell 1. A guide tube 2 is fixedly connected to the surface of the shell 1. A digging rod 3 is slidably arranged axially inside the shell 1. A temporary storage cavity 4 is formed inside the digging rod 3, extending through both ends. A top cover 5 is fixedly connected to the top of the shell 1. A top rod 6, coaxially arranged with the digging rod 3, is fixedly connected to the lower surface of the top cover 5. The top rod 6 is adapted to the temporary storage cavity 4. When the digging rod 3 moves upward, the top rod 6 inserts into the temporary storage cavity 4 and pushes out the soil in the temporary storage cavity 4.

[0027] Specifically, by moving the digging rod 3 downwards, the digging rod 3 is inserted into the soil, allowing the soil to enter the temporary storage chamber 4. When the digging rod 3 moves upwards, it causes the soil in the temporary storage chamber 4 to move, forming a pit on the ground. Fertilizer is then poured into the pit through the feed pipe 2 for fertilization. By continuing to move the digging rod 3 upwards, the top rod 6 is inserted into the temporary storage chamber 4 and pushes the soil out, thus filling the pit. This allows the fertilization tool for ginkgo planting to quickly fill pits.

[0028] Several stop blocks 7 are fixedly connected to the bottom of the inner wall of the temporary storage cavity 4. The stop blocks 7 are arranged in a circular array at the bottom of the temporary storage cavity 4. The stop blocks 7 are triangular in shape, and the surface of the stop blocks 7 is formed with a connecting wall 8, a stop wall 9, an inclined wall 10, and a side wall 11, respectively. The connecting wall 8 is fixedly connected to the temporary storage cavity 4. The stop wall 9 is located on the upper side of the inclined wall 10 to prevent the soil from exiting the temporary storage cavity 4 due to gravity. By setting the stop wall 9, after the soil enters the temporary storage cavity 4, it is prevented from falling out of the temporary storage cavity 4 due to its own gravity.

[0029] Two first cutting blades 12 are symmetrically arranged on the inclined wall 10 to form a double-blade cutting structure, which cuts the soil and reduces resistance when the digging rod 3 is pressed down.

[0030] A transverse cutting blade 13 is provided on the side wall 11. The cutting edge of the transverse cutting blade 13 is perpendicular to the axial direction of the digging rod 3. When the digging rod 3 rotates, the transverse cutting blade 13 radially cuts the soil column to form an annular separation surface, which makes it easy to leave the soil in the temporary storage cavity 4 when the digging rod 3 moves upward.

[0031] A sliding ring 14 is slidably connected to the inner wall of the outer casing 1, and a rotating column 15 is rotatably connected to the inner wall of the sliding ring 14. A mounting hole is provided at the top of the rotating column 15, and the digging rod 3 is fixedly connected in the mounting hole. By setting the sliding ring 14, the digging rod 3 can slide along the axial direction of the outer casing 1. By setting the rotating column 15, the digging rod 3 can be rotated easily.

[0032] A U-shaped push rod 16 is fixedly connected to the top of the rotating column 15. The top of the push rod 16 extends to the outside of the outer casing 1. An clearance opening 17 for the rotation of the push rod 16 is provided on the upper surface of the top cover 5. The push rod 16 is designed to facilitate user operation. The clearance opening 17 allows the push rod 16 to rotate at a certain angle, which in turn allows the digging rod 3 to rotate at a certain angle so that the transverse cutting blade 13 can cut the soil column.

[0033] A base plate 18 is fixedly connected to the bottom of the outer shell 1, and a base 19 is fixedly connected to the upper surface of the base plate 18. The base 19 is located inside the outer shell 1. A funnel-shaped guide groove 20 is provided on the top of the base 19. A through hole 21 adapted to the digging rod 3 is provided on the inner bottom wall of the guide groove 20. A pedal 22 is fixedly connected to the surface of the base plate 18. By setting the guide groove 20, fertilizer is guided and soil is guided when filling.

[0034] The bottom of the digging rod 3 is provided with a second cutting blade 23 to reduce the resistance when the digging rod 3 is pressed down.

[0035] Working principle: When using this fertilization tool for ginkgo planting, the user first moves the device to the target location, then stands it upright on the ground, steps on the pedal 22 for stability, and then presses the push rod 16. The push rod 16 drives the digging rod 3 downward, passing through the through hole 21 and penetrating into the soil. After reaching the required depth, the user stops pressing the push rod 16. During this process, soil enters the temporary storage chamber 4 to form a soil column. Then, the user rotates the push rod 16, which drives the rotating column 15 to rotate. The rotating column 15 drives multiple stops. Block 7 rotates, and with the cooperation of multiple stop blocks 7, the soil column is cut to form a separation surface, which facilitates its breakage. Then, the push rod 16 is lifted upward, and the lifting rod drives the digging rod 3 and the soil column existing in the digging rod 3 to move upward into the outer shell 1. Then, fertilizer is put into the guide pipe 2. After the fertilizer enters the outer shell 1, it enters the pit through the guide groove 20 and the through hole 21. Then, the digging rod 3 continues to move upward, so that the top rod 6 is inserted into the temporary storage cavity 4 and pushes out the soil to fill the pit, thus enabling the fertilization tool for ginkgo planting to have the effect of quickly filling the pit.
