Description

Technical Field

[0001] The invention relates to the technical field of medicinal material irrigation, and in particular to an automatic medicinal material irrigation device. Background Art

[0002] In the process of medicinal material cultivation, reasonable irrigation is one of the key factors to ensure the normal growth and yield quality of medicinal materials.

[0003] Traditional irrigation methods often rely on manual judgment or fixed irrigation schedules, which is not only inefficient but also difficult to accurately control the amount of irrigation, which can easily lead to waste of water resources or damage to medicinal materials due to insufficient / excessive irrigation.

[0004] Especially at different stages of medicinal material growth, the demand for soil moisture is different. The difference in soil moisture between the surface and the roots is often ignored, resulting in unsatisfactory irrigation effects.

[0005] In order to overcome this problem, some automated irrigation systems have begun to appear on the market, but most of these systems adopt a unified irrigation strategy and fail to make precise adjustments based on the actual soil moisture required by the medicinal materials. They generally directly irrigate the surface near the medicinal materials, resulting in a slower water replenishment speed.

[0006] Therefore, how to design a device that can adaptively adjust the irrigation strategy according to the growth environment of medicinal materials and changes in soil moisture has become an urgent problem to be solved in the current field of medicinal material cultivation. Summary of the invention

[0007] The invention provides an automatic medicinal material irrigation device to solve the problem that the existing irrigation device has a slow water replenishment speed for medicinal materials.

[0008] In order to alleviate the above technical problems, the technical solution provided by the present invention is:

[0010] The lifting mechanism includes a lifting rod sliding in the watering rod, and the water supply mechanism also includes a flexible tube for supplying water to the watering rod. Two humidity sensors are vertically arranged in the stratum where medicinal materials are planted. The upper humidity sensor is used to detect the soil moisture at the surface, and the lower humidity sensor is used to detect the soil moisture at the roots of the medicinal materials. An electromagnetic valve is arranged on the flexible tube, and when the soil moisture at the surface decreases, the electromagnetic valve opens widely, so that the pressure in the watering rod increases rapidly to make the lifting rod extend, so that the water outlet sprays water close to the surface. When the soil moisture at the roots of the medicinal materials decreases, the electromagnetic valve opens slightly, so that the pressure in the watering rod increases slowly, so that the lifting rod does not extend, so that the water outlet sprays water close to the roots of the medicinal materials.

[0011] Furthermore, the water supply mechanism also includes a water pipe, which is installed in the medicinal field, and the flexible pipe is connected to the water pipe.

[0012] Furthermore, the water supply mechanism also includes a hollow ring, the plurality of watering rods are connected to the hollow ring, and the flexible tube is connected to the hollow ring.

[0013] Furthermore, the lifting mechanism also includes a limiting ring connected to the inside of the watering rod, a tension spring is connected between the limiting ring and the lifting rod, the water outlet is Z-shaped, and one end of the water outlet is opened on the outer wall of the watering rod, and the other end of the water outlet is opened on the inner wall of the watering rod between the top of the lifting rod and the limiting ring.

[0014] Furthermore, it also includes a water spraying mechanism, which includes an arc rod, the arc rod is connected to the hollow ring, and a water spraying hole is opened on the arc rod. When the lifting rod is extended so that the hollow ring moves upward, the water spraying hole sprays water to the medicinal material leaves.

[0015] Furthermore, the water spraying mechanism also includes a baffle, and a pull rope is connected between the baffle and the lifting rod. When the lifting rod is extended, the baffle is pulled by the pull rope so that the arc rod is connected to the hollow ring.

[0016] Furthermore, the water spray mechanism also includes a counterweight block, which slides in the inner cavity of the lifting rod, the top port diameter of the inner cavity is smaller than the counterweight block, and the end of the pull rope is connected to the counterweight block.

[0017] Furthermore, the inner wall of the hollow ring is connected with a magnetic ring, and the baffle is magnetically attracted to the magnetic ring.

[0018] Furthermore, the upper surface of the baffle is connected to a limit rod, and the magnetic ring is provided with a hole that cooperates with the limit rod.

[0019] Furthermore, there are multiple arc-shaped rods, and a ring array of multiple arc-shaped rods is connected to the upper part of the hollow ring and is arranged one-to-one corresponding to the multiple watering rods.

[0020] The beneficial effects of the present invention are analyzed as follows:

[0021] The invention discloses an automatic irrigation device for medicinal materials, comprising a water supply mechanism and a lifting mechanism. The water supply mechanism comprises a circular plate placed around the medicinal materials, a plurality of hollow rods are connected in an annular array on the lower surface of the circular plate, through grooves are provided on the side walls of the hollow rods, watering rods are inserted in the plurality of hollow rods, and water outlet holes are provided on the side walls of the watering rods; the lifting mechanism comprises a lifting rod sliding in the watering rod, the water supply mechanism also comprises a flexible pipe for supplying water to the watering rod, two humidity sensors are vertically arranged in the stratum where the medicinal materials are planted, the upper humidity sensor is used to detect the soil humidity at the surface, and the lower humidity sensor is used to detect the soil humidity at the root of the medicinal materials, an electromagnetic valve is arranged on the flexible pipe, and when the soil humidity at the surface decreases, the electromagnetic valve is opened widely, so that the pressure in the watering rod increases rapidly so that the lifting rod is extended, so that the water outlet hole sprays water close to the surface, and when the soil humidity at the root of the medicinal materials decreases, the electromagnetic valve is opened slightly, so that the pressure in the watering rod increases slowly, so that the lifting rod does not extend, so that the water outlet hole sprays water close to the root of the medicinal materials.

[0022] The water supply mechanism irrigates the medicinal materials adaptively according to the humidity of the soil. Two humidity sensors are set, one for detecting the soil humidity close to the surface, and the other for detecting the soil humidity at the root of the medicinal materials. The hollow rod is directly buried in the soil, and the medicinal materials are located in the middle of the circular plate. When the humidity at the surface decreases, the upper humidity sensor detects a signal, causing the opening of the solenoid valve to increase to the maximum. At this time, the water flow supplied to the watering rod increases, thereby increasing the pressure in the watering rod. At this time, the lifting rod is pushed by the pressure to slide outside the watering rod. At this time, the lifting rod The bottom of the watering rod is blocked by the bottom of the hollow rod, so that the watering rod moves upward, and the water outlet hole opened on the side wall of the watering rod moves upward along the through groove, so that the upper soil layer is irrigated, and when the lower humidity sensor detects that the humidity has dropped, the opening of the solenoid valve is low, so that the water flow entering the watering rod is low, so that the lifting rod does not slide relative to the watering rod, and the water flows out from the water outlet to the root position of the medicinal material; through the above arrangement, the device can directly water the dry parts of the soil, so that the medicinal materials can be irrigated in time, thereby improving the water replenishment speed of the medicinal materials.

[0038] For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Examples, such as Figure 1-Figure 7 As shown, an automatic irrigation device for medicinal materials includes a water supply mechanism 100 and a lifting mechanism 200. The water supply mechanism 100 includes a circular plate 130 placed around the medicinal materials. A plurality of hollow rods 140 are connected in an annular array on the lower surface of the circular plate 130. A through groove 150 is provided on the side wall of the hollow rod 140. Watering rods 170 are inserted into the plurality of hollow rods 140. Watering rods 170 are provided on the side wall of the watering rods 170. The lifting mechanism 200 includes a lifting rod 210 that slides in the watering rod 170. The water supply mechanism 100 also includes a flexible pipe 120 for supplying water to the watering rod 170, which is located between the medicinal materials and the water supply mechanism 100. Two humidity sensors are vertically arranged in the planting layer, the upper humidity sensor is used to detect the soil humidity at the surface, and the lower humidity sensor is used to detect the soil humidity at the roots of medicinal materials. A solenoid valve is arranged on the flexible tube 120, and when the soil humidity at the surface decreases, the solenoid valve opens widely, so that the pressure in the watering rod 170 increases rapidly to make the lifting rod 210 extend, so that the water outlet 171 sprays water close to the surface; when the soil humidity at the roots of medicinal materials decreases, the solenoid valve opens slightly, so that the pressure in the watering rod 170 increases slowly, so that the lifting rod 210 does not extend, so that the water outlet 171 sprays water close to the roots of medicinal materials.

[0040] The working mechanism of the automatic irrigation device provided in this embodiment is as follows:

[0041] The device can be used for automatic irrigation of indoor or outdoor medicinal fields, for example, the medicinal materials are in indoor cultivation racks, suspended between the soil and the ground;

[0042] The water supply mechanism 100 irrigates the medicinal materials adaptively according to the humidity of the soil. Two humidity sensors are provided, one for detecting the soil humidity close to the surface and the other for detecting the soil humidity at the root of the medicinal materials. The hollow rod 140 is directly buried in the soil. The medicinal materials are located in the middle of the circular plate 130. When the humidity at the surface decreases, the upper humidity sensor detects a signal, so that the opening of the solenoid valve increases to the maximum. At this time, the water flow supplied to the watering rod 170 increases, thereby increasing the pressure in the watering rod 170. At this time, the lifting rod 210 is affected by the humidity. The lifting rod 210 slides outwards of the watering rod 170 due to the pressure. At this time, the bottom of the lifting rod 210 is blocked by the bottom of the hollow rod 140, so that the watering rod 170 moves upwards, and the water outlet 171 opened on the side wall of the watering rod 170 moves upwards along the through groove 150, so that the upper soil layer is irrigated. When the lower humidity sensor detects that the humidity has dropped, the opening of the solenoid valve is low, so that the water flow entering the watering rod 170 is low, so that the lifting rod 210 does not slide relative to the watering rod 170, and the water will also flow out from the water outlet 171 to the root position of the medicinal material;

[0043] Through the above arrangement, the device can directly water the dry parts of the soil, so that the medicinal materials can be irrigated in time, thereby improving the water replenishment speed of the medicinal materials.

[0044] Among the optional methods of this embodiment, the more preferred ones are:

[0045] The water supply mechanism 100 further includes a water pipe 110 . The water pipe 110 is installed in the medicinal field, and the flexible pipe 120 is connected to the water pipe 110 .

[0046] The water flow in the water pipe 110 has sufficient pressure, so that when the solenoid valve on the flexible tube 120 is opened, the water flow can flow into the corresponding watering rod 170, and the flexible tube 120 can be deformed so that the lifting and lowering of the watering rod 170 is not interfered.

[0047] Among the optional methods of this embodiment, the more preferred ones are:

[0048] The water supply mechanism 100 further includes a hollow ring 160 , a plurality of watering rods 170 are all connected to the hollow ring 160 , and the flexible tube 120 is connected to the hollow ring 160 .

[0049] The water in the flexible tube 120 is supplied into the hollow ring 160 , and then the water flows through the hollow ring 160 into the watering rod 170 .

[0050] Regarding the structure of the lifting mechanism 200, specifically:

[0051] The lifting mechanism 200 also includes a limiting ring 220 connected to the inside of the watering rod 170, a tension spring 230 is connected between the limiting ring 220 and the lifting rod 210, the water outlet hole 171 is Z-shaped, and one end of the water outlet hole 171 is opened on the outer wall of the watering rod 170, and the other end of the water outlet hole 171 is opened on the inner wall of the watering rod 170 between the top of the lifting rod 210 and the limiting ring 220.

[0052] The setting of the tension spring 230 makes it difficult for relative sliding to occur between the lifting rod 210 and the watering rod 170, so that the lifting rod 210 can resist sliding when the water pressure in the watering rod 170 is low. On the other hand, when the solenoid valve is closed, the lifting rod 210 can slide and reset relative to the watering rod 170, and the water outlet 171 is set to be Z-shaped, and one end of the water outlet 171 is opened on the outer wall of the watering rod 170, and the other end of the water outlet 171 is opened on the inner wall of the watering rod 170 between the top of the lifting rod 210 and the limit ring 220, to ensure that the water outlet 171 will not be blocked when the lifting rod 210 slides relative to the watering rod 170.

[0053] Regarding the structure of the water spray mechanism 300, specifically:

[0054] The water spraying mechanism 300 includes an arc rod 310 connected to the hollow ring 160 and having a water spraying hole 311 thereon. When the lifting rod 210 is extended so that the hollow ring 160 moves upward, the water spraying hole 311 sprays water toward the medicinal material leaves.

[0055] When the soil moisture near the surface decreases, it means that the external temperature is high or the humidity is low. At this time, the watering rod 170 moves up, so that the soil near the surface is directly irrigated. At the same time, the hollow ring 160 connected to the watering rod 170 moves up. At this time, the arc rod 310 on the hollow ring 160 moves up, so that the arc rod 310 is close to the leaf part of the medicinal material, and then the water spray hole 311 sprays water to the leaves of the medicinal material, so that the leaves of the medicinal material are sprayed with water, further improving the water replenishment effect on the medicinal material.

[0056] Among the optional methods of this embodiment, the more preferred ones are:

[0057] The water spray mechanism 300 further includes a baffle 330 , and a pull rope 340 is connected between the baffle 330 and the lifting rod 210 . When the lifting rod 210 is extended, the baffle 330 is pulled by the pull rope 340 so that the arc rod 310 is connected to the hollow ring 160 .

[0058] When the lifting rod 210 extends out of the watering rod 170, the hollow ring 160 moves up. At this time, the lifting rod 210 pulls the baffle 330 through the pull rope 340, so that the baffle 330 moves down, so that the bottom end of the arc rod 310 is not blocked. At this time, the hollow ring 160 is connected with the arc rod 310, so that the water flow can be sprayed out through the water spray hole 311. When the water flow is sprayed out, the pressure in the hollow ring 160 decreases, and the tension spring 230 pulls the lifting rod 210 to move up, and the baffle 330 is no longer pulled. At this time, the arc rod 310 stops spraying water. Subsequently, the pressure of the hollow ring 160 increases again, so that the baffle 330 is pulled again, and this cycle is repeated, so that the water spray hole 311 continuously sprays water on the leaves of the medicinal material.

[0059] Among the optional methods of this embodiment, the more preferred ones are:

[0060] The water spray mechanism 300 also includes a counterweight block 350 , which slides in the inner cavity 360 of the lifting rod 210 . The top port diameter of the inner cavity 360 is smaller than that of the counterweight block 350 . The end of the pull rope 340 is connected to the counterweight block 350 .

[0061] The counterweight block 350 slides in the inner cavity 360 of the lifting rod 210, and the pull rope 340 is connected to the counterweight block 350, so that the pull rope 340 is received by the inner cavity 360, ensuring that the counterweight block 350 can move to the top port of the inner cavity 360 only when the hollow ring 160 rises to the uppermost part. At this time, the lifting rod 210 pulls the baffle 330 through the counterweight block 350 and the pull rope 340.

[0062] Among the optional methods of this embodiment, the more preferred ones are:

[0063] The inner wall of the hollow ring 160 is connected to a magnetic ring 320 , and the baffle 330 and the magnetic ring 320 are magnetically attracted to each other.

[0064] The magnetic ring 320 magnetically adsorbs the baffle 330 , so that when the pull rope 340 does not pull the baffle 330 , the magnetic ring 320 adsorbs the baffle 330 , so that the arc rod 310 no longer sprays water.

[0065] Among the optional methods of this embodiment, the more preferred ones are:

[0066] The upper surface of the baffle 330 is connected to a limiting rod 331 , and the magnetic ring 320 is provided with a hole that matches the limiting rod 331 .

[0067] The setting of the limiting rod 331 limits the moving track of the baffle 330, so that the arc rod 310 can be opened and closed when the baffle 330 moves.

[0068] Among the optional methods of this embodiment, the more preferred ones are:

[0069] There are multiple arc rods 310 , which are connected to the upper part of the hollow ring 160 in a circular array and are arranged one-to-one corresponding to the multiple watering rods 170 .

[0070] By providing a plurality of arc-shaped rods 310, the leaves of the medicinal material can be sprayed with water over a large range, thereby improving the water replenishment effect on the medicinal material.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
