Description

Technical Field

[0001] The utility model relates to the technical field of planting, in particular to a slow infiltration type cultivation device. Background Art

[0002] The cultivation device is a kind of vessel used for planting flowers, green plants, etc. The device has various forms and sizes. The grower can choose the cultivation device according to the characteristics and needs of the plant. According to the different watering methods, the cultivation device can be divided into many types. Currently, there are two commonly used cultivation devices: upper watering and bottom watering. Among them, most of the cultivation devices are upper watering, that is, watering the potting soil directly from the top of the flowerpot. This method is suitable for general plants and is also the most commonly used watering method for plants. This watering method is prone to the phenomenon of wet top, leaking bottom and dry in the middle, especially some compacted soils have poor water absorption capacity. When watering, water will flow away from the cracks in the soil, causing the soil surface to be relatively moist, but many places inside the soil are still relatively dry, affecting the growth of plant roots. Moreover, the moisture on the soil surface will evaporate, causing water waste. In addition, the bottom watering method is the opposite of the previous method. This method is to water from the bottom of the flower pot, that is, use a larger pot or bucket, fill it with a certain amount of water, place the flower pot in it, and the water slowly moistens the pot soil through the holes at the bottom of the pot until the surface soil is moist. However, this method takes a long time to moisten the soil in the middle and upper parts of the pot, and the soil at the bottom of the pot is constantly wet, which is easy to breed pests and diseases, and will also cause root hypoxia and rot, affecting the growth of plants. Therefore, there is still a need for a cultivation device that can water the soil in the pot thoroughly and evenly without causing water accumulation in the pot. Utility Model Content

[0027] Example

[0028] like Figure 1-5 As shown, the utility model provides a slow infiltration cultivation device, which includes an inner basin 100, an outer basin 200 and a water diversion device 300.

[0029] The pot bodies of the inner pot 100 and the outer pot 200 are of a common structure with a large mouth and a small bottom. The inner pot 100 is placed in the outer pot 200. The inner pot 100 is used to grow plants, and the outer pot 200 is used to store water.

[0030] The shapes of the inner basin 100 and the outer basin 200 are not limited, and can be inverted frustum or inverted prism or other shapes. A water diversion device 300 is provided in the inner basin 100, and water from the outer basin 200 is introduced into the inner basin 100 through the water diversion device 300 for plant irrigation.

[0031] The water diversion device 300 includes an insertion portion 310 and a water outlet portion 320. The water outlet portion 320 is a hollow cylinder, and the insertion portion 310 is a hollow cone or truncated cone. The water diversion device 300 is inserted into the soil using the pointed end of the insertion portion 310. The diameter of the bottom surface of the insertion portion 310 is consistent with the outer diameter of the water outlet portion 320. The insertion portion 310 and the water outlet portion 320 are an integrally formed structure. A plurality of water outlet holes 321 are evenly arranged on the side of the water outlet portion 320. The water outlet holes 321 are preferably circular, and the number of the water outlet holes 321 is set according to the size of the inner basin 100. The water diversion device 300 is arranged on the bottom wall or side of the inner basin 100, and a water diversion hole 110 is arranged at a position on the inner basin 100 corresponding to the water diversion device 300. The size of the water diversion hole 110 is adapted to the cross-sectional size of the water outlet 320. Preferably, the diameter of the water diversion hole 110 is consistent with the inner diameter of the water outlet 320, so as to facilitate the water in the outer basin 200 to be introduced into the water diversion device 300 through the water diversion hole 110.

[0032] Furthermore, a base 140 is provided at the bottom of the inner basin 100. The shape of the base 140 is not limited, as long as it can support the inner basin 100 and the outer basin 200 to be separated by a distance, so as to prevent water from accumulating at the bottom of the inner basin 100 and causing root rot of plants. The base can be an integral structure or several separate bases, such as four arc-shaped bases. The placement position of the base 140 is staggered with the position of the water diversion hole 110, so as not to affect the water inlet of the water diversion device 300. Preferably, the base 140 is evenly distributed radially along the outer circumference of the bottom wall of the inner basin 100, so as to support the inner basin 100 more stably.

[0033] Furthermore, a drainage hole 130 is provided at the center of the bottom wall of the inner basin 100 to prevent water accumulation in the inner basin 100 from causing root rot of the plant. The drainage hole 130 and the inner basin 100 may be integrally formed or movably connected, preferably integrally formed. When the drainage hole 130 and the inner basin 100 are an integrally formed structure, the drainage hole 130 is a hollow truncated cone structure with a large mouth and a small bottom, that is, the cross-section of the drainage hole 130 is a trapezoid that is wide at the top and narrow at the bottom, the upper surface of the drainage hole 130 is flush with the bottom wall of the inner basin 100, and the lower surface of the drainage hole 130 is higher than the bottom surface of the base 140. When water accumulates in the inner basin 100, the drainage hole 130 can drain the inner basin; when there is little water in the inner basin 100, the drainage hole 130 can absorb water from the inner basin, while also preventing a large amount of water at the bottom of the inner basin 100 from pouring into the inner basin, causing the soil at the bottom of the inner basin to become wet and waterlogged.

[0034] Furthermore, ventilation holes 120 are provided on the side of the inner pot 100, and the provision of the ventilation holes 120 can promote the flow and circulation of air inside the soil of the inner pot 100. During the growth of the plant, sufficient oxygen and fresh air are required to ensure its breathing and metabolism. By providing ventilation holes 120 on the side of the inner pot 100, the ventilation effect of the soil in the inner pot can be effectively increased, and the flow of air can be maintained, which is beneficial to root breathing and nutrient absorption. The ventilation holes 120 can be uniformly arranged radially along the side of the inner pot 100, and the shape of the ventilation holes 120 is preferably circular, and the number of ventilation holes 120 is set in one or more circles according to the size and needs of the inner pot.

[0035] Furthermore, the height of the outer basin 200 is lower than the height of the ventilation holes 120 on the inner basin to facilitate air intake and exhaust of the ventilation holes 120 .

[0036] Furthermore, flanges are provided at the top openings of the inner basin 100 and the outer basin 200 to facilitate taking and placing the basin body. The flanges are preferably concave arc-shaped curved structures.

[0037] Furthermore, a water absorption rope 340 is arranged in the water diversion device 300, and the water absorption rope 340 passes through the water diversion device 300 and extends into the inner pot 100. One end of the water absorption rope 340 is immersed in the water of the outer pot 200, and the other end of the water absorption rope 340 is placed in the soil of the inner pot 100. Water is continuously transferred to the soil of the inner pot from bottom to top through the water absorption rope. The water slowly penetrates into the soil of the inner pot 100 through the water absorption rope 340, so as to achieve slow and continuous watering of the plants, which can avoid too much watering at one time, causing root rot of the plants.

[0038] The number of water-absorbing ropes 340 is set as needed. One water-absorbing rope 340 can be set in each water-drawing device 300, or multiple water-absorbing ropes 340 can be set in each water-drawing device 300. The multiple water-absorbing ropes 340 pass through different water outlet holes 321 respectively. Preferably, the diameter of the water-absorbing rope 340 is slightly smaller than and close to the diameter of the water outlet hole 321, so that the water-absorbing rope 340 can pass through the water outlet hole 321 and absorb as much water as possible.

[0039] The material of the absorbent rope 340 can be absorbent cotton thread or fiber material, preferably a cotton strip made of cotton, which has good water absorption, is soft and easy to install.

[0040] Furthermore, a soil moisture sensor is provided in the inner basin 100, preferably a direct-insertion soil moisture sensor, which can be directly inserted into the soil to be measured, has high measurement accuracy and fast response, and can be moved up and down in the soil to achieve dynamic observation of the moisture content of each soil layer. The humidity sensor is connected to a display instrument to display humidity numbers in real time, and can also be used with an RS485 converter to upload data to a remote computer or mobile phone.

[0041] Furthermore, a layer of expanded clay is placed at the bottom of the inner pot 100 to enhance air permeability and prevent water accumulation at the bottom of the pot from suffocating the roots.

[0042] Furthermore, a layer of expanded clay is placed on the surface of the soil in the inner pot 100 to retain water and fertilizer.

[0043] Based on the above structure, the water diversion device 300 also has the following extended embodiments.
