Description

Technical Field

[0001] This utility model belongs to the technical field of planting auxiliary devices, specifically relating to a combined plant planting device. Background Technology

[0002] Deserts and wastelands, with their scarce rainfall, are unfavorable for plant growth. Currently, the main methods of desert greening are planting psammophytes, building windbreaks on desert edges, and artificial water supply. Greening arid regions is a long-term and arduous task. Traditional planting mats often suffer from insufficient sand-fixing capacity, poor water retention, and low seed germination rates when used in desert areas due to the minimal utilization of moisture in the air and soil, thus failing to meet the specific needs of these regions.

[0003] Existing plant growth mat technology is mostly used in environments with mature irrigation technology, which can replenish the water and nutrients needed for plant growth at any time. However, it is relatively expensive to manufacture and is rarely suitable for resource-scarce desert areas. Utility Model Content

[0004] The purpose of this invention is to provide a combined plant planting device that can automatically replenish water and has both sand fixation and water retention functions as well as stability.

[0005] The technical solution adopted by this utility model is: a combined plant planting device, which includes a soil covering layer, a replenishment layer, an anti-slip layer and a bottom layer from top to bottom. A humidity sensor and a water storage pipe are horizontally buried in the replenishment layer. One end of the water storage pipe has a vertically upward water inlet, which is connected to the water inlet. The water storage pipe is provided with multiple water outlets.

[0006] The feature of this utility model is that,

[0007] Furthermore, four through holes are symmetrically arranged on one side of the water storage pipe. A metal sensor is embedded near the outer side of each through hole, and a spring is welded to the metal sensor. The spring is located inside the through hole, and the other end of the spring is connected to a stainless steel plate, which is located inside the water storage pipe and can completely cover all the water outlet holes. The metal sensor is connected to a humidity sensor via an insulated wire. The metal sensor is also connected to a solar panel via a wire to achieve self-powered operation. When the humidity sensor detects that the soil moisture has dropped to a level unsuitable for plant root growth, the humidity sensor starts to work, the circuit is completed, and the output current is transmitted through the metal sensor to the spring, causing it to extend and lift the stainless steel plate. Water in the water storage pipe seeps out from the water outlet holes, achieving self-watering.

[0008] Furthermore, after welding, the metal induction sheet, spring, and stainless steel sheet are coated with a material to prevent leakage.

[0009] Furthermore, the bottom layer is made of biodegradable plastic film material, which has good air permeability, prevents plant root necrosis, and does not pollute the environment.

[0010] Furthermore, the anti-slip layer is made of a mixture of gravel and high-strength fiber materials; it prevents soil movement while making the blanket less prone to slipping.

[0011] Furthermore, the replenishment layer is made of a mixture of humus and water-retaining materials, including organic fertilizer, plant fiber, leaf mold, waste straw, water-retaining agent, and microbial agent. After the humus combines with soil particles, it can form a more stable aggregate structure, ensuring the nutrients needed for plant growth while improving the soil's water retention capacity.

[0012] Furthermore, the topsoil layer is made by mixing crushed grass seeds and straw with silt. The grass seeds and straw can decompose naturally into nutrients containing phosphorus and calcium, while the silt is a natural fertilizer. The combination of the two can provide a good growing environment for the seeds.

[0013] Furthermore, the diameter of the water inlet is equal to the outer diameter of the water inlet pipe, and the water inlet pipe is inserted into the water inlet; both the water storage pipe and the water inlet pipe are made of PVC.

[0014] Furthermore, the spring is a memory metal spring made of H59 brass with a conductivity of 20-25% IACS; it has relatively high strength, certain strength and corrosion resistance, and it expands when heated by electricity and contracts when cooled down after power is cut off.

[0015] Furthermore, the width of the stainless steel sheet is greater than the coverage width of all the water outlet holes, and in the open circuit state, the stainless steel sheet completely blocks the water outlet holes.

[0016] Furthermore, the spring and metal sensing plate are chrome-plated.

[0017] The beneficial effects of this utility model are as follows: The combined plant planting device proposed in this utility model uses a supply layer in which humus and soil particles combine to form a more stable aggregate structure, ensuring the nutrients required for plant growth and the water retention of the soil. The water supply group is a circuit as a whole. When the humidity sensor works, its own resistance decreases, forming a circuit with the solar cell, metal induction plate, spring and stainless steel plate. When current flows through the spring, it generates heat. Due to the temperature rise, the spring made of shape memory metal will extend. At this time, the spring will lift the stainless steel plate, exposing the water outlet hole that was originally covered by the stainless steel plate. Water in the water storage pipe flows into the planting group from the water outlet hole, realizing self-watering and preventing the plant roots from lacking water or having no water. The chrome plating makes the components in the humid environment less susceptible to corrosion. The arrangement of the bottom layer and anti-slip layer makes the planting group itself less likely to move in the horizontal direction. Attached Figure Description

[0027] Example 2

[0028] Based on Example 1,

[0029] After welding, the metal induction plate 12, spring 11, and stainless steel sheet 13 are all attached with anti-leakage material. The solar panel 14 can then be placed on the ground to achieve self-powered operation. Plant seeds are sown on the replenishment layer 3 and covered with the soil layer 4. When this planting group is laid in multiple locations, parallel connection between water supply groups can also be achieved.

[0030] After welding, the metal induction plate 12, spring 11, and stainless steel plate 13 are coated with anti-leakage material.

[0031] Example 3

[0032] This utility model is a combined plant planting device, which includes, from top to bottom, a soil covering layer 4, a replenishment layer 3, an anti-slip layer 2 and a bottom layer 1. A humidity sensor 10 and a water storage pipe 6 are horizontally embedded in the replenishment layer 3. One end of the water storage pipe 6 has a vertically upward-facing water inlet 8, which is connected to a water inlet pipe 7. The water storage pipe 6 is provided with multiple water outlet holes 9.

[0033] The bottom layer 1 is made of biodegradable plastic film material, which has good air permeability, prevents plant root necrosis, and does not pollute the environment.

[0034] The anti-slip layer 2 is made of a mixture of gravel and high-strength fiber materials, which prevents soil flow and makes the planting group less prone to slipping.

[0035] The replenishment layer 3 is made of a mixture of humus and water-retaining materials, including organic fertilizer, plant fiber, leaf mold, waste straw, water-retaining agent, and microbial inoculant. After the humus combines with soil particles, it can form a more stable aggregate structure, ensuring the nutrients needed for plant growth while improving the soil's water retention capacity.

[0036] The topsoil layer 4 is made by mixing crushed grass seeds and straw with silt. Grass seeds and straw can decompose naturally into nutrients containing phosphorus and calcium, while silt is a natural fertilizer. The combination of the two can provide a good growing environment for the seeds.

[0037] Four through holes are symmetrically arranged on one side of the water storage pipe 6. A metal sensor 12 is embedded near the outside of the through hole. A spring 11 is welded to the metal sensor 12. The spring 11 is located in the through hole. The other end of the spring 11 is connected to a stainless steel sheet 13. The stainless steel sheet 13 is located in the water storage pipe 6 and can completely cover all the water outlet holes 9. The metal sensor 12 is connected to the humidity sensor 10 through an insulated wire 15. The metal sensor 12 is connected to the solar panel 14 through a wire to realize self-powered power supply.

[0038] Example 4

[0039] Based on Example 3,

[0040] The water storage pipe 6 is equipped with a vertically upward-facing water inlet 8. The diameter of the water inlet 8 must be equal to the outer diameter of the water inlet pipe 7. The water inlet pipe 7 must be inserted into the water inlet 8 tightly. Both the water storage pipe 6 and the water inlet pipe 7 are made of PVC and are used to connect to an external water source.

[0041] The allowable insertion depth of spring 11 is approximately equal to its length when it has no elastic potential energy. Spring 11 is made of H59 brass, a shape memory metal with a conductivity of approximately 20-25% IACS. It has relatively high strength, a certain degree of strength and corrosion resistance. It expands when heated by electricity and contracts when cooled down by power-off.

[0042] The width of stainless steel sheet 13 is slightly larger than the width of the water outlet 9 area. In the open circuit state, stainless steel sheet 13 completely blocks the water outlet 9.

[0043] When the humidity sensor 10 detects that the soil moisture has dropped to a level unsuitable for plant root growth, the humidity sensor 10 starts to work, the circuit forms a path, and the output current is transmitted through the metal sensing plate 12 to the spring 11, causing it to extend and lift the stainless steel plate 13. Water in the water storage pipe 6 seeps out from the water outlet 9, realizing self-watering.

[0044] After all welding work is completed, the spring 11 and the metal induction plate 12 are chrome plated to improve their wear resistance and corrosion resistance.

[0045] After the humidity sensor 10 is connected to the water storage pipe 6, it is buried in the planting group. They can be connected in parallel with the solar panel 14 and the external water source.

[0046] Example 5

[0047] This utility model is a combined plant planting device, which includes, from top to bottom, a soil covering layer 4, a replenishment layer 3, an anti-slip layer 2 and a bottom layer 1. A humidity sensor 10 and a water storage pipe 6 are horizontally embedded in the replenishment layer 3. One end of the water storage pipe 6 has a vertically upward-facing water inlet 8, which is connected to a water inlet pipe 7. The water storage pipe 6 is provided with multiple water outlet holes 9.

[0048] A base layer 1 is laid on the ground, made of biodegradable plastic film material, which has good air permeability, prevents plant root necrosis, and does not pollute the environment. An anti-slip layer 2, made of a mixture of gravel and high-strength fiber material, is placed on top of the base layer 1 to prevent soil flow and make the planted group less prone to slipping. A replenishment layer 3 is then laid on top of the anti-slip layer 2, made of a mixture of humus and water-retaining materials, including organic fertilizer, plant fiber, leaf mold, waste straw, water-retaining agent, and microbial inoculant. The humus, combined with soil particles, forms a more stable aggregate structure, ensuring the nutrients needed for plant growth while improving the soil's water retention.

[0049] A humidity sensor 10 and a water storage pipe 6 are horizontally embedded in the supply layer 3. One end of the water storage pipe 6 has a vertically upward-facing water inlet 8, which is connected to a water inlet pipe 7 outside the planting group. The diameter of the water inlet 8 must be equal to the outer diameter of the water inlet pipe 7. The water inlet pipe 7 must be inserted into the water inlet 8 tightly. Both the water storage pipe 6 and the water inlet pipe 7 are made of PVC and are used to connect to an external water source.

[0050] Drill a hole in the water storage pipe 6 on the side facing the center of the planting group, insert a metal induction plate 12 near the outside of the hole, and then weld a spring 11 inward. The depth of the spring 11 is allowed to be equivalent to the length of the spring 11 when it has no elastic potential energy. The spring 11 is made of H59 brass shape memory metal with a conductivity of 24% IACS, relatively high strength, and certain strength and corrosion resistance. It expands when the power is applied and heat is generated, and contracts after the power is cut off and the temperature is cooled.

[0051] The humidity sensor 10 is connected to an external insulated wire 15, which is welded to a metal sensing plate 12 at one end. The width of the stainless steel plate 13 is slightly larger than the width of the water outlet 9. In the open circuit state, the stainless steel plate 13 completely blocks the water outlet 9. The stainless steel plate 13 is connected to the other end of the spring 11, and the current path in the water storage pipe 6 is realized through the stainless steel plate 13.

[0052] The metal sensor 12 is connected to the solar panel 14 outside the planting group via wires. After the metal sensor 12, spring 11, and stainless steel sheet 13 are welded, they are all attached with anti-leakage material. The solar panel 14 can be placed on the ground to achieve self-powered power supply.

[0053] When the humidity sensor 10 detects that the soil moisture has dropped to a level unsuitable for plant root growth, the humidity sensor 10 starts to work, the circuit forms a path, and the output current is transmitted through the metal sensing plate 12 to the spring 11, causing it to extend and lift the stainless steel plate 13. Water in the water storage pipe 6 seeps out from the water outlet 9 to replenish the water.

The grass seeds and straw can decompose naturally into nutrients containing P, Ca, etc., and the silt is a natural fertilizer. The combination of the two can provide a good growing environment for the seeds.
