Description

Technical Field

[0001] This utility model belongs to the field of soil improvement equipment, and in particular relates to a soil conditioner injector. Background Technology

[0002] Ecological landscaping engineering, based on ecological principles, utilizes scientific planning and engineering techniques to construct a multi-layered, multi-functional, and sustainable green space system, achieving synergistic development of ecological, social, and economic benefits. Its core lies in mimicking natural ecosystems, promoting material cycling and energy flow, while simultaneously considering aesthetics and functionality. Soil improvement is a crucial component of ecological landscaping engineering; it optimizes soil structure and regulates nutrient balance to enhance land productivity and ecological benefits, laying the foundation for subsequent greening projects.

[0003] Currently, when using soil conditioners, the main method is to loosen the soil using tilling machinery, then sprinkle the soil conditioner into the soil, and then mix the soil conditioner with the loosened soil again using tilling machinery. In practice, to maintain the soil improvement effect, it is necessary to loosen the soil multiple times and sprinkle the soil conditioner into it multiple times, which makes the cost of using existing technology for soil improvement high and the operation cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a soil conditioner injector that can continuously inject conditioner into the soil.

[0005] The soil conditioner injector includes a vertically arranged rod. The lower half of the rod has several independent inner cavities along its length. For each inner cavity, several interconnected water outlet holes are formed on the outer wall of the rod. A movable sleeve is fitted onto the rod to block the water outlet holes. The sleeve has a locking element to lock the moved sleeve onto the rod. An upward-opening connecting box is fixed to the top of the rod. An infusion tube for transmitting the conditioner is connected between the connecting box and each inner cavity. The connecting box has an adding component for adding the conditioner to its contents.

[0006] Furthermore, the added component includes a mounting sleeve, which is vertically fixed to the top of the connecting box. The mounting sleeve has an opening on its side wall that communicates with the inside and outside. An syringe is independently installed inside the mounting sleeve, and the nipple of the syringe is installed inside the connecting box. A sealing ring for sealing the gap between the connecting box and the syringe is installed on the top of the connecting box. A slot for engaging the two side wings of the syringe is provided at the opening. A pressure plate for squeezing the piston handle of the syringe is independently installed inside the mounting sleeve, and a spring is installed between the pressure plate and the top of the mounting sleeve.

[0007] Furthermore, several handles are horizontally fixed on the outer wall of the mounting sleeve.

[0008] Furthermore, a sliding groove is provided on the inner wall of the mounting sleeve, and a slider is fixed on the side wall of the pressure plate, which is independently installed in the sliding groove and moves up and down along the sliding groove.

[0009] Furthermore, a cone head is fixed to the bottom of the insertion rod, and a spiral blade is fixed to the outer wall of the cone head.

[0010] Furthermore, a tube embedding groove is provided on the side wall of the insertion rod, and all infusion tubes are independently engaged in the tube embedding groove.

[0011] Furthermore, the retaining sleeve has a scale along its length for checking the depth of the insertion rod into the soil.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The lower half of the insert is inserted deep into the soil. A soil conditioner is added to the connection box via a component. The soil conditioner is then delivered to all the inner cavities through each infusion tube. The soil conditioner in the inner cavities is then discharged from the outlet holes, injecting it into the soil around the insert. This makes injecting the soil conditioner easier and simpler; only the syringe needs to be replaced afterward, allowing for continuous injection of the conditioner into the soil. The injection method is simple and convenient, saving labor costs. When the lower half of the insert needs to be inserted into the soil, a cover blocks all the outlet holes to prevent soil from clogging them. After the lower half of the insert is fully inserted into the soil, the cover slides upward to expose all the outlet holes, allowing the soil conditioner flowing from them to enter the soil.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0023] This embodiment describes a soil conditioner injector, such as... Figure 1 , Figure 2 and Figure 6 As shown, it includes a vertically arranged insertion rod 6, which is a cylindrical rod. The cylindrical insertion rod 6 can be rotated more easily when inserted into the soil.

[0024] A cone head 10 is fixed to the bottom of the insertion rod 6, and a spiral blade 11 is fixed to the outer wall of the cone head 10; such as Figure 1 , Figure 5 and Figure 6 As shown, the cone 10 has a conical structure. The cone 10 breaks through the soil with its tip, making it easier to insert the lower end of the insertion rod 6 into the soil. The edge of the spiral blade 11 is relatively sharp. When rotating, it cuts the soil like a "miniature knife", directly "digging" a threaded groove in the soil. The threads of a wood screw are usually deep and sharp. When rotating, it cuts the wood fibers like a "miniature knife", directly "digging" a threaded groove in the wood. The cut threaded groove matches the spiral blade 11. When rotating later, the spiral blade 11 will "hook" the edge of the threaded groove, continuously pulling the cone 10 to move deeper into the ground. This principle is the same as the principle of screws being installed on a wooden board. The cone 10 and the spiral blade 11 make it easier for the lower end of the insertion rod 6 to be inserted into the soil. When the insertion rod 6 is inserted to a suitable depth, the spiral blade 11 will be blocked by the soil without reversing, thus preventing the insertion rod 6 from coming out of the hole.

[0025] The lower half of the insertion rod has several independent internal cavities along its length, such as... Figure 1 , Figure 2 and Figure 4As shown, the inner cavity 12 is located on the lower half of the insertion rod 6, and all the inner cavities 12 are evenly distributed along the length of the insertion rod 6. When the lower half of the insertion rod 6 is inserted into the soil, the evenly distributed inner cavities 12 correspond to soil layers at different depths, so that water can be injected into soil layers at different depths during water injection, allowing the soil conditioner to be more evenly distributed in all directions after being injected into the soil.

[0026] For each inner cavity, several interconnected water outlet holes are provided on the outer wall of the insertion rod; such as Figure 2 As shown, the water outlet 13 is used to connect the inner cavity 12 with the outside, so that the soil conditioner in the inner cavity 12 flows from the water outlet 13 to the soil outside the insertion rod 6; and the water outlet 13 is evenly distributed on the inner wall of the inner cavity 12 along the circumference, which can make the soil conditioner in the inner cavity 12 diffuse more evenly in all directions.

[0027] A retaining sleeve 9, which can move along the insert rod 6 and is used to block the water outlet 13, is fitted onto the insert rod 6; for example Figure 1 As shown, when the lower half of the insertion rod 6 needs to be inserted into the soil, the retainer 9 can be slid onto the lower half of the insertion rod 6 to block all the water outlet holes 13, preventing the soil from clogging the water outlet holes 13 when the lower half of the insertion rod 6 is inserted into the soil; after the lower half of the insertion rod 6 is fully inserted into the soil, the retainer 9 can be slid upward to expose all the water outlet holes 13, allowing the soil conditioner flowing out of the water outlet holes 13 to enter the soil;

[0028] The retaining sleeve 9 has a scale along its length for checking the depth of the insertion of the rod 6 into the soil; when the rod 6 is inserted into the soil, the depth of insertion can be checked through the scale to ensure the accuracy of the insertion of the rod 6 into the soil.

[0029] The retaining sleeve is equipped with a locking element for locking the moved retaining sleeve onto the insert rod; such as Figure 1 As shown, in this embodiment, the locking mechanism uses a screw. A threaded hole is provided on the outer tube wall of the upper end of the retaining sleeve 9, which is threaded to engage with the screw. When the retaining sleeve 9 moves to a suitable position, the screw can be rotated so that the end of the screw presses against the insert rod 6, thereby locking the moved retaining sleeve 9. Alternatively, a positioning pin can be used as the locking component. The positioning pin is independently installed on the outer tube wall of the retaining sleeve 9. Two positioning holes are provided on the tube wall of the insert rod 6, which are spaced vertically. When the retaining sleeve 9 blocks all the water outlet holes 13, the positioning pin is aligned with the lower positioning hole. At this time, the positioning pin is inserted into the aligned positioning hole to lock the lowered retaining sleeve 9. When the retaining sleeve 9 moves upward and exposes all the water outlet holes 13, the positioning pin is aligned with the upper positioning hole. At this time, the positioning pin is inserted into the aligned positioning hole to lock the uppered retaining sleeve 9.

[0030] The top of the insertion rod 6 is fixed with an upward-facing connecting box 14, such as... Figure 3 As shown, the connecting box 14 is mainly used to receive the soil conditioner discharged from the syringe 5;

[0031] An infusion tube 7 for transmitting the modifier is connected between the connecting box 14 and each inner cavity 12, such as... Figure 1 As shown, each inner cavity 12 is connected to an infusion tube 7, and the other end of all infusion tubes 7 is connected to the bottom of the infusion tube 7 and communicates with the inside of the connecting box 14. The soil conditioner in the connecting box 14 can be delivered to each inner cavity 12 through all the infusion tubes 7. Since the length between each inner cavity 12 and the connecting box 14 is different, the length of the connected infusion tubes 7 is different. Therefore, the resistance can be compensated by adjusting the diameter of the infusion tubes 7 (for example, a larger diameter is used for longer branch tubes), so that uniform water supply can be achieved to ensure that soil at different depths can receive more uniform soil conditioner injection. Of course, the infusion tubes 7 can also be optimized individually (such as by adding a throttling valve) to specifically solve the resistance difference.

[0032] The side wall of the insertion rod 6 is provided with a tube embedding groove, and all infusion tubes 7 are independently snapped into the tube embedding groove; such as Figure 1 As shown, all the infusion tubes 7 are secured in the tube embedding groove, which stores and protects all the infusion tubes 7 to prevent them from being damaged by the outside world. A sealing plate is installed at the opening of the tube embedding groove with screws to seal the groove and prevent the infusion tubes 7 from being damaged by the outside world.

[0033] To elaborate further, such as Figure 1 , Figure 3 and Figure 5 As shown, this embodiment preferably includes a mounting sleeve 1, which is vertically fixed to the top of the connecting box 14. The mounting sleeve 1 has an opening on its side wall that communicates with the inside. An syringe 5 is independently inserted into the mounting sleeve 1. In use, the opening is mainly used for assembling and disassembling the syringe 5, and the mounting sleeve 1 stores and places the syringe 5. The tip of the syringe 5 is inserted into the connecting box 14, and a sealing ring 15 is installed on the top of the connecting box 14 to seal the gap between the connecting box 14 and the syringe 5. Figure 3 As shown, when the syringe 5 is installed inside the housing 1, the nipple of the syringe 5 passes through the connecting box 14, and the soil conditioner is injected into the connecting box 14 through the syringe 5; while the sealing ring 15 seals the gap between the syringe 5 and the top of the connecting box 14 to prevent the soil conditioner from leaking out of the gap; the opening is provided with a groove for engaging the wing plates on both sides of the syringe 5, such as Figure 5As shown, after the nipple of the syringe 5 is inserted into the connecting box 14, the wing plates on both sides of the syringe 5 are respectively engaged in two slots, which fix the syringe 5 in place and prevent it from moving, thus ensuring the sealing ring 15 seals the gap between the syringe 5 and the top of the connecting box 14. A pressure plate 2 for squeezing the piston handle of the syringe 5 is independently installed inside the mounting sleeve 1, and a spring 4 is installed between the pressure plate 2 and the top of the mounting sleeve 1. When the syringe 5 is placed inside the mounting sleeve 1, the pressure plate 2 adheres to the piston handle of the syringe 5, and the spring 4... The pressure plate 2 moves downwards by its own elasticity, pushing the piston handle. The piston squeezes the soil conditioner in the injection cylinder 5, injecting the soil conditioner into the connecting box 14. No manual pushing is required, making soil conditioner injection easier and simpler. A groove is provided on the inner wall of the mounting sleeve 1. A slider, independently inserted into and moving up and down along the groove, is fixed to the side wall of the pressure plate 2. The groove and slider work together to guide the movement of the pressure plate 2, preventing it from tilting or deflecting during movement. The upper part has a threaded hole, and a screw with a threaded engagement is inserted into the threaded hole. When installing the syringe 5, the pressure plate 2 is moved upward to make room for the syringe 5. The screw is rotated so that it presses against the inner wall of the mounting sleeve 1, thereby locking the pressure plate 2. After the syringe 5 is in place, the screw is rotated in the opposite direction to release the lock on the pressure plate 2, allowing the spring 4 to push the pressure plate 2 to compress the piston handle. This scheme constitutes an additive assembly for adding modifier inside the connecting box 14. Of course, the additive assembly can also be a liquid storage bag. The top of the connecting box 14 is equipped with an upward-facing storage box. A swing plate that swings inward is hinged to the opening of the storage box. A torsion spring is installed between the swing plate and the storage box. An external threaded sleeve is installed at the outlet of the liquid storage bag. An internal thread that is threaded to the external threaded sleeve is provided on the inner wall of the connecting box 14. The external threaded sleeve is connected to the connecting box 14 and communicates with the connecting box 14. When the liquid storage bag is placed in the storage box, the swing plate is pushed and squeezed on the liquid storage bag by the torsion spring. The soil conditioner in the liquid storage bag flows into the connecting box 14 under the pressure.

[0034] Several handles 3 are horizontally fixed on the outer wall of the mounting sleeve 1, such as Figure 1 As shown, there are two handles 3, which are symmetrically distributed on the left and right sides. Users can operate this soil conditioner injector by holding both handles 3.

[0035] In actual use, the cone 10 is inserted into the soil. This soil conditioner injector causes the cone 10 to move deeper into the soil under the drive of the spiral blade 11. This allows the cone 10 to drive the lower half of the insert rod 6 into the soil depth. Once the insert rod 6 is inserted to the appropriate depth, the retaining sleeve 9 is moved upwards to expose all the water outlet holes 13. Then, the syringe 5 is placed into the bag housing sleeve 1. The nipple of the syringe 5 is inserted into the connecting box 14, and the gap is sealed by the sealing ring 15. The wing plates on both sides of the syringe 5 are respectively engaged in two slots, which fix the syringe 5 in place to prevent movement. The pressure plate 2 is attached to the piston handle of the syringe 5, and the spring 4 is held in place by its own... The elastic self-propelled pressure plate 2 moves downward, causing pressure plate 2 to push piston handle. The piston squeezes the soil conditioner in injection cylinder 5, injecting the soil conditioner into connecting box 14. The soil conditioner in connecting box 14 is then delivered to all inner cavities 12 through each infusion tube 7. The soil conditioner in inner cavities 12 is discharged from water outlet 13, injecting the soil conditioner into the soil around the insertion rod 6, making the injection of soil conditioner easier and simpler. If multiple injections of soil conditioner are required in the future, there is no need to remove this soil conditioner injector; only injection cylinder 5 needs to be replaced. This allows for continuous injection of soil conditioner, making the injection method simple and convenient and saving labor costs.
