Description

Technical Field

[0001] The present invention relates to the technical field of sapling transplanting tools, and particularly to a garden sapling transplanting spade. Background Art

[0002] A sapling transplanting spade is a tool designed specifically for horticultural operations, especially suitable for tasks such as digging soil, lifting saplings, and transplanting saplings. Modern spades have far more technical features than the existing ones. Depending on different environments, the specific situations of use are also different. However, currently, ordinary spades are more commonly used for transporting saplings.

[0003] The existing ordinary spades have the following disadvantages when used for saplings: (1) Firstly, there is a large resistance when entering the soil, and the effect of truncating thick roots is not good. It is easy to damage the roots of saplings, and the operation convenience and efficiency are insufficient. At the same time, it lacks the flexibility to adapt to different space requirements. (2) When the existing spades enter the soil, they often face greater resistance, resulting in the user having to spend more effort to complete the digging action. When encountering thick rotten roots, the existing spades are often difficult to effectively truncate, which is not only inefficient but also easily causes unnecessary damage to the roots of saplings. Due to design defects of the existing spades, such as a single cutting method at the edge, it is easy to cause unnecessary damage to the roots of saplings during the process of truncating the roots, affecting the survival rate of saplings. (3) The existing spades often lack sufficient convenience and efficiency during the operation process. For example, they lack designs such as cutting sawteeth that can adapt to roots of different diameters, resulting in the user having to spend more time and energy to complete the sapling transplanting work. (4) The existing spades often have a handle of only one fixed length and cannot be flexibly adjusted according to space limitations. When the user faces special situations such as a narrow space, it is often impossible to use the spade to efficiently transplant saplings. Therefore, the present application designs a transplanting spade that can solve the above problems. Summary of the Invention

Detailed implementation mode

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0037] Embodiment 1: Refer to Figures 1 to 18, A garden sapling transplanting spade, including a main handle 1 and a spade base 2 installed at the bottom end of the main handle 1. A fixing seat 3 is installed at the bottom end of the spade base 2, and a crossbeam-shaped spade shoulder 4 is installed at the bottom end of the fixing seat 3. And a spade head 5 is integrally formed at the bottom of the spade shoulder 4. The spade head 5 is in the shape of a trapezoidal surface that is wider at the top and narrower at the bottom. And a V-shaped cutting groove 7 for truncating the main root of the sapling is recessed upward in the middle of the bottom end of the spade head 5. A plurality of cutting saw teeth 6 are evenly arranged at equal intervals on both side walls of the spade head 5. And the arrangement density between the cutting saw teeth 6 on one side of the spade head 5 is greater than the arrangement density between the cutting saw teeth 6 on the other side, for dividing the work of sawing the roots of saplings of different thicknesses; The spade base 2, the spade shoulder 4, the connecting block, the spade head 5 and the cutting saw teeth 6 are all made of manganese steel. Cutting edges are provided on both sides and the bottom of the spade head 5; A connecting component is installed at the top end of the main handle 1, and a sub-handle 9 is installed above the connecting component. A T-shaped handle 10 is provided at the top end of the sub-handle 9. And a rotary locking component for horizontal angle adjustment is provided at the bottom end of the T-shaped handle 10; A fixing component for preventing the spade shoulder 4 from coming off is provided at the bottom of the fixing seat 3; Anti-loose plugs 11 are screwed on both ends of the T-shaped handle 10. A storage cavity for storing a hexagon wrench is opened inside the upper part of the T-shaped handle 10. And the hexagon wrench for disassembling and assembling the spade head 5 is stored in the storage cavity on the T-shaped handle 10, which is convenient for real-time disassembly and assembly operations of the spade head 5. Through the cooperation of the spade head 5, the cutting saw teeth 6 with different spacings on both sides, and the V-shaped cutting groove 7 with staggered scissors edges, it can not only effectively reduce the resistance when the spade head 5 enters the soil. When the spade head 5 is shoveled into the soil, if it encounters thick rotten roots, by repeatedly lifting the spade head 5, it is convenient to saw off the roots of the sapling through the cutting saw teeth 6. And because the tooth pitch between the cutting saw teeth 6 on both sides of the spade head 5 is different, it can be selected according to the roots of different diameters to cut the roots of the sapling. At the same time, it can directly achieve the purpose of staggered cutting of the roots of the sapling, playing a role of shearing and breaking, avoiding the situation that it is easy to be unable to effectively truncate due to the movement of the roots when a single cutting edge cuts the roots. Moreover, it can improve the convenience of the truncation operation between the roots around the sapling and the soil body, and can play a role of truncating the roots in place at one time, avoiding the situation that the ordinary spade cannot effectively truncate the roots of the sapling after being inserted into the soil layer multiple times and is easy to damage the roots of the sapling.

[0038] In the present invention, a ribbed stop block 17 in the shape of an arc-shaped plate is fixedly connected to the front end of the bottom of the fixed seat 3. A semi-circular connecting plate protrudes from the front end of the middle part of the spade shoulder 4. The spade head 5 is integrally in the shape of an arc-shaped plate structure, and the bending radian range of the spade head 5 is between ten degrees and twenty degrees. The cutting edges in the V-shaped cutting groove 7 are arranged in a scissors-like dislocation. A reinforcing bar 8 welded vertically at the rear end of the middle part of the bottom surface of the spade shoulder 4 is fused with the spade head 5. The two sides of the spade head 5 are bent forward in an arc shape. Under the action of the arc-shaped spade head 5, the soil mass after the root system is truncated can be pushed and extruded towards the sapling direction, so that the soil mass wraps around the root system around the sapling, forming a soil mass 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.

Countersunk holes are opened on the circumferential side of the top surface of the second round seat 27, and leading connecting bolts 30 are screwed into the countersunk holes. A second screw hole for cooperating with the second screw rod 28 is opened in the middle of the bottom end surface of the sub-handle 9, and first screw grooves are opened on the circumferential side of the bottom surface of the sub-handle 9 for cooperating with the connecting bolts 30. Through the cooperation of the main handle 1, the sub-handle 9 and the connecting component, it is convenient to achieve the purpose of assembling the device into a short-handled spade and a long-handled spade according to needs, effectively improving the situation where a long-handled spade cannot be used due to space limitations during the transplantation of saplings.

[0043] Working principle: In this embodiment, the present invention also proposes a method for using a garden sapling transplanting spade, including the following steps:

[0044] Step 1: First, drive the cooperation of the connecting stud 24 by rotating the hexagonal block 31, install the spade seat 2 at the bottom end of the main handle 1, and insert the plug-in block 32 at the top of the fixed seat 3 into the limit groove at the bottom end of the main handle 1. At this time, the spade seat 2 is sleeved on the bottom end of the main handle 1, improving the connection stability and strength between the spade seat 2 and the main handle 1. Then connect the anti-loosening bolt 25 to the spade seat 2 and the connecting stud 24 to prevent the main handle 1 and the spade seat 2 from deflecting and loosening after connection;

[0045] Step 2: Next, install the spade shoulder 4 on the spade head 5 at the top of the fixed seat 3. When installing the spade shoulder 4, make the connecting block fit on the top of the fixed seat 3, and make the reinforced stop block 17 abut against the front end of the connecting block to limit it and prevent the spade shoulder 4 from warping after installation. At the same time, the positioning post 18 and the fixing screw 19 on the hexagonal block 31 will pass through the connecting block at this time, and install the anti-rotation ring 20 and the locking nut 21 on the fixing screw 19, thus completing the installation operation between the spade seat 2 and the spade head 5. To further prevent the installed spade shoulder 4 from loosening, pass the positioning bolt 23 through the reinforced stop block 17 and insert the inner end of the positioning bolt 23 into the positioning groove of the positioning post 18, thus completing the further limit and anti-loosening effect after the installation of the spade shoulder 4;

[0046] Step 3: When a short-handled spade is needed, there is no need to use the connecting component and the sub-handle 9. Just directly install the T-shaped handle 10 with the rotary locking component at the top end of the main handle 1, thus meeting the need for short-handled use. And at this time, the unused sub-handle 9 and the connecting component can play the role of a crowbar when the root of the sapling needs to be lifted during the process of transplanting the sapling, and can also cooperate with the crossbar and the rope to lift and transport the sapling. If a long-handled state is needed, install the sub-handle 9 at the top end of the main handle 1 through the connecting component, thus achieving the long-handled requirement state during use. And when pushing the positioning sleeve 16 to move into the annular groove at the bottom of the T-shaped handle 10, the positioning convex block 34 can be withdrawn from the locking groove, and then the T-shaped handle 10 can be rotated to adjust the angle, facilitating the formation of different holding angles between the T-shaped handle 10 and the spade head 5, and improving the applicable range of the shoveling force applied by the user to the spade head 5 during the sapling transplanting process;

[0047] Step 4: After the overall shovel is assembled, hold the T-shaped handle 10 by hand, step on the top side of one side of the shovel shoulder 4 and press down forcefully. Under the action of the V-shaped cut groove 7, the shovel head 5 can easily enter the soil layer. When the shovel head 5 shovels into the soil, the downwardly inclined cutting saw teeth 6 on both sides can be used to cut off the roots in the soil with a diameter of no more than five centimeters. If encountering thick humus roots, by repeatedly lifting the shovel head 5, it is convenient to saw off the roots of the sapling through the cutting saw teeth 6. And because the tooth pitch between the cutting saw teeth 6 on both sides of the shovel head 5 is different, it is possible to select the appropriate one to cut the roots of the sapling according to the diameter of the roots.

[0048] Step 5: At the same time, through the V-shaped cut groove 7 at the bottom of the shovel head 5 and the cutting edges on both sides and at the bottom, the speed of cutting off the roots of the sapling can be improved. And through the scissors-shaped staggered cutting edge arrangement inside the V-shaped cut groove 7, not only can the resistance when the shovel head 5 enters the soil be effectively reduced, but also when the shovel head 5 shovels into the soil, it can directly achieve the purpose of misaligned cutting of the roots of the sapling, playing a role of shearing and breaking, avoiding the situation that a single cutting edge is prone to ineffective truncation due to root movement when cutting the roots, improving the convenience of the truncation operation between the roots around the sapling and the soil body, and being able to achieve the effect of truncating the roots in place at one time, avoiding the situation that an ordinary shovel cannot effectively truncate the roots of the sapling after being inserted into the soil layer multiple times and is prone to damaging the roots of the sapling. After truncating the roots around the sapling, by pressing down the main handle 1 and the sub-handle 9 backward, the arc-shaped shovel head 5 can push and squeeze the soil body after truncating the roots towards the sapling, so that the soil body can wrap around the roots around the sapling, forming a soil ball at the root of the sapling, thereby improving the survival rate of the sapling after transplantation and the convenience and efficiency of the sapling during transplantation.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
