Description

Technical Field

[0001] The invention relates to the technical field of seedling transplanting tools, in particular to a garden seedling transplanting shovel. Background Art

[0002] A shovel for transplanting saplings is a tool designed for gardening operations, especially for tasks such as digging, lifting and transplanting saplings; modern shovels are far more than these existing technical features, and the specific circumstances in which they are used vary according to the various environments, but currently most ordinary shovels are used to transplant saplings; The existing common shovels have the following disadvantages when used for saplings: (1) First, there is a large resistance to entering the soil, which is not effective in cutting off thick roots and is easy to damage the roots of the saplings. In addition, the operation convenience and efficiency are insufficient, and the shovels lack the flexibility to adapt to different space requirements. (2) The existing shovels often face great resistance when entering the soil, which requires the user to spend more effort to complete the digging action. When encountering thick humus roots, the existing shovels are often difficult to cut off effectively, which is not only inefficient but also easy to cause unnecessary damage to the roots of the saplings. Due to the design defects of the existing shovels, such as the single cutting method of the blade edge, It is easy to cause unnecessary damage to the roots of the seedlings in the process of cutting off the roots, affecting the survival rate of the seedlings; (3) The existing shovels often lack sufficient convenience and efficiency during operation, such as the lack of cutting saw teeth that can adapt to roots of different diameters, which causes users to spend more time and energy to complete the transplanting of seedlings; (4) The existing shovels often have only one handle of fixed length and cannot be flexibly adjusted according to space constraints. When the user faces special circumstances such as a small space, it is often impossible to use the shovel for efficient seedling transplanting.

[0022] Working principle: In this embodiment, the present invention also proposes a method for using a garden sapling transplanting shovel, comprising the following steps: Step 1: First, the shovel seat 2 is installed on the bottom end of the main handle 1 by rotating the hexagonal block 31 to drive the connection stud 24 to cooperate, and the plug-in block 32 on the top of the fixing seat 3 is plugged into the limiting groove at the bottom end of the main handle 1. At this time, the shovel seat 2 is sleeved on the bottom end of the main handle 1 to improve the stability and connection strength of the connection between the shovel seat 2 and the main handle 1, and the anti-detachment bolt 25 is connected to the shovel seat 2 and the connection stud 24 to prevent the main handle 1 and the shovel seat 2 from deflecting and loosening after the connection; The second step is to install the shovel shoulder 4 with the shovel head 5 on the top of the fixing seat 3. When installing the shovel shoulder 4, the connecting block is fitted on the top of the fixing seat 3, and the reinforced stopper 17 is abutted against the front end of the connecting block to limit it, so as to prevent the shovel shoulder 4 from warping after installation. At the same time, the positioning column 18 and the fixing screw 19 on the hexagonal block 31 will pass through the connecting block at this time, and be installed on the fixing screw 19 by installing the anti-rotation ring 20 and the locking nut 21, thereby completing the installation operation between the shovel seat 2 and the shovel head 5. In order to further prevent the shovel shoulder 4 from loosening after installation, the positioning bolt 23 is passed through the reinforced stopper 17, and the inner end of the positioning bolt 23 is inserted into the positioning groove of the positioning column 18, thereby completing the further limiting and anti-falling effect of the shovel shoulder 4 after installation. In step 3, when the shovel in the short-handle state is needed, the connecting assembly and the auxiliary handle 9 are not needed. The T-handle 10 with the rotating locking assembly only needs to be directly installed on the top of the main handle 1, so as to meet the demand for the short-handle use. At this time, the auxiliary handle 9 and the connecting assembly are not used. In the process of transplanting saplings, when the roots of the saplings need to be lifted, they can act as a crowbar, and can act as a cross bar to cooperate with the rope to lift the saplings; if the long-handle state is needed, the auxiliary handle 9 is installed on the top of the main handle 1 through the connecting assembly, so as to meet the long-handle requirement state when in use; and by pushing the positioning sleeve 16 to move toward the annular groove at the bottom of the T-handle 10, the positioning protrusion 34 can be withdrawn from the locking groove, so that the T-handle 10 can be rotated to adjust the angle, so that the T-handle 10 can form different grip angles with the shovel head 5, thereby improving the applicable range of the user's shoveling force applied to the shovel head 5 during the shovel transplanting process; Step 4, after the overall shovel is assembled, hold the T-shaped handle 10 with your hand, step on the top of one side of the shovel shoulder 4 with your foot and press down hard, the shovel shoulder 4 makes the shovel head 5 easily enter the soil layer under the action of the V-shaped cutting groove 7, and when the shovel head 5 is shoveled into the soil, the cutting saw teeth 6 inclined downward on the left and right sides can be used to shovel and cut off the roots in the soil with a diameter of no more than five centimeters. If a thick humus root system is encountered, the shovel head 5 can be pulled back and forth to facilitate the sawing operation of the root system of the sapling by the cutting saw teeth 6, and because the tooth spacing between the cutting saw teeth 6 on both sides of the shovel head 5 is different, it can be used to cut the root system of the sapling according to the root system of different diameters; Step 5. At the same time, the V-shaped groove 7 at the bottom of the shovel head 5 and the cutting edges on both sides and the bottom can improve the speed of cutting the roots of the saplings. In addition, the scissor-shaped staggered cutting edges inside the V-shaped groove 7 can not only effectively reduce the resistance of the shovel head 5 when entering the soil, but also directly achieve the purpose of dislocation cutting of the roots of the saplings when the shovel head 5 is shoveled into the soil, thereby achieving the effect of shearing and breaking, avoiding the situation in which the roots cannot be effectively cut off due to the movement of the roots when cutting with a single blade edge, thereby improving the convenience of cutting the roots around the saplings and the soil. The shovel head 5 has the advantages of good toughness, can cut off the root system in one go, and avoid the situation that an ordinary shovel is inserted into the soil layer for multiple times but still cannot effectively cut off the root system of the sapling and easily causes damage to the root system of the sapling; after cutting off the roots around the sapling, by pressing the main handle 1 and the auxiliary handle 9 backward, the arc-shaped shovel head 5 can push and squeeze the soil after the root system is cut off toward the sapling, so that the soil can be wrapped around the root system around the sapling to form a soil ball at the root of the sapling, thereby improving the survival rate of the sapling after transplantation and improving the convenience and efficiency of the sapling during transplantation.
