Description

Technical Field

[0001] The present invention relates to the technical field related to forestry planting, and in particular to a fertilizing device for forestry planting. Background Art

[0002] In order to facilitate the absorption of nutrients by trees and ensure the growth of their root systems during forestry planting, a fertilizing device is needed to provide the nutrients required by the plants. However, the existing fertilizing devices for forestry planting still have certain defects when used, such as; During use, the traditional fertilization method requires manual trenching, fertilization, and landfilling. The overall operation is time-consuming and labor-intensive, and most of the fertilization is done manually, which makes the labor intensity high and leads to low fertilization efficiency. In order to overcome the above defects, prior art 1 (Chinese patent application number 202022593623.8, application date 2020-11-11) is a fertilizing device for forestry planting, comprising a base, two sets of pillars are fixedly connected to the upper end of the base, a liquid storage tank is fixedly connected to the upper end of the pillar, a driving assembly is provided at the left end of the first rotating shaft, a plurality of stirring blades are provided on the outer wall of the first rotating shaft, a lifting assembly is connected to the right end of the first rotating shaft, a soil-breaking rod is fixedly connected to the output end of the first motor, and a material blocking assembly is provided in the middle of the discharge pipe; through the driving assembly The components drive the stirring blades to rotate to stir and mix the fertilizer and water, so that the fertilizer can be mixed evenly and thoroughly. The forward and reverse rotation of the first rotating shaft drives the soil-breaking rod to move up and down through the lifting component. When the soil-breaking rod descends, the soil can be broken. The blocking component can make the fertilizer fall intermittently and quantitatively to avoid excessive or insufficient fertilization affecting the growth of trees. After the fertilization is completed, when the device continues to move, the covering plate can cover the soil just broken back into the broken pit, which can reduce the volatilization of the fertilizer and improve the fertilizer efficiency. There is no need for subsequent manual covering, which reduces the labor intensity. There is also prior art 2 (Chinese patent application number 201920002490.7, application date 2019-01-02) a fertilizing device for forestry planting, comprising a base and a box body, a box body is installed on the top of the base, a feeding port is provided on the top of the box body, a storage box is installed at the bottom of the feeding port, two sets of support rods are installed at the bottom of the storage box, a control device is installed on the top of the base, a first cylinder is installed at one end of the box body away from the feeding port, a slider is installed at the output end of the first cylinder, a support frame is installed at one end of the base away from the control device, a slide groove is provided inside the support frame, a slider is installed inside the slide groove, an L-shaped bracket, a second cylinder and a sealing plate are provided, the L-shaped bracket fixes the second cylinder to the bottom of the storage box, and the second cylinder pushes the sealing plate to move at the bottom of the storage box, which can avoid wasting fertilizer and accurately control the fertilizer material, and prevent the phenomenon of burning seedlings caused by excessive fertilization; And prior art 3 (Chinese patent with application number 202322168253.7 and application date 2023-08-11) A fertilizing device for forestry planting, comprising a base with walking wheels, a barrel and a digging mechanism provided on the top of the base, a quantitative feeding mechanism provided between the barrel and the base, and the digging mechanism located on the discharge end side of the quantitative feeding mechanism. By providing the digging mechanism, the electric push rod cooperates with the second drive motor and the drill bit to realize automatic digging. The quantitative feeding mechanism can realize quantitative fertilization of plants through the first drive motor in conjunction with the feeding pipe, the rotating shaft and the spiral blades. The arrangement of the base, walking wheels and push handle facilitates the movement of the device, thereby replacing traditional manual fertilization operations, reducing labor intensity, shortening fertilization time, and effectively improving fertilization efficiency.

[0003] Although the existing technology can reduce the intensity of manual labor, during the working process, the fertilization operation is carried out through the cooperation of the digging mechanism and the feeding mechanism. The overall process requires digging the hole first and then feeding the material, which increases the overall fertilization time and reduces the fertilization efficiency. In addition, the feeding mechanism is located on one side of the digging mechanism, which causes the fertilization position to shift, thereby affecting the accuracy of fertilizer placement and resulting in unsatisfactory fertilization effect. The overall fertilizer is sprinkled on the side of the digging hole, which is easy to cause volatilization, thereby reducing the fertilizer utilization rate.

[0004] In view of the above problems, it is urgently necessary to carry out innovative design based on the original forestry planting fertilization device. Therefore, we have proposed a forestry planting fertilization device that can well solve the above problems. Summary of the Invention
