Description

Technical Field

[0001] The invention relates to the field of water conservancy irrigation, and in particular to a soil moisture detection device used for information water conservancy irrigation. Background Art

[0002] Water conservancy irrigation technology is increasingly widely used in today's increasingly important agricultural production activities. In addition to simply meeting the water demand for farmland irrigation, people have an increasing demand for automated farmland irrigation. In existing farmland irrigation technology, farmland is often irrigated with set water supply parameters, and water is transported to farmland for irrigation by controlling water pumps and pipelines. However, in most cases, existing technologies use experience to determine the time and amount of water required for irrigation of farmland, or arrange to transport the corresponding amount of water when it is detected that the farmland is close to water shortage. This will make the moisture in the farmland and the dryness and humidity in the soil prone to large changes, which is not conducive to the growth of crops, especially in the case of global warming and severe greenhouse effect. Climate change is more complex and difficult to predict. Dry and wet weather may also alternate in a short period of time, making it impossible for crops to grow in a soil with a more stable dryness and humidity level, so that crops do not get the best growth environment, affecting the harvest of agricultural production.

[0003] The currently disclosed Chinese patent CN202110828780.9 is a farmland water conservancy irrigation system with adjustable water volume, including a pumping device, a water supply pipeline, an irrigation device, a predictive monitoring device and a control device; the pumping device is connected to a water source to pump water out of the water source; the water supply pipeline extends to the farmland that needs to be irrigated and is connected to the pumping device, and the pumping device pumps the pumped water into the water supply pipeline and transports it to the location of the farmland; the irrigation device is arranged at the location of the farmland, connected to the water supply pipeline, and discharges the water in the water supply pipeline onto the farmland; the predictive monitoring device is arranged at the location of the farmland, including an air guide pipe and a monitoring component, the lower end of the air guide pipe is inserted into the soil of the farmland at a set depth, and its upper end The air duct extends to a position at a set height above the soil, and an air inlet is provided at its upper end. The air inlet is provided at the position of the above-ground detection probe of the monitoring component, and the above-ground detection probe detects the state parameters of the air at the position; the lower end of the air guide duct is provided with an exhaust valve, and an underground detection probe of the monitoring component is provided in the soil at a set distance outside the exhaust valve, and the underground detection probe detects the state parameters of the soil at the position; the control device is connected to the pumping device, the irrigation device and the predictive monitoring device by signal; the control device obtains the state parameters of the air and the soil, and obtains the control instruction according to the set calculation rules, and the control device sends the control instruction to the pumping equipment and the irrigation device, and the pumping equipment and the irrigation device act according to the control instruction.

[0004] According to the above patent, the patent uses a predictive monitoring device to set the change relationship of the soil moisture at a specified depth under the influence of the temperature and humidity of the surface air, and introduces the corresponding surface air to the soil at a specified depth through an air duct to obtain an accelerated change effect, thereby obtaining in advance the influence relationship of the surface air on the soil moisture at a specified depth, and obtaining the empirical curve coefficient based on the experimental data to obtain a control signal for controlling the irrigation flow. However, this detection method, when detecting soil air, easily introduces soil into the air duct, which is easy to block it and is not conducive to the detection of soil moisture. Therefore, there is a need for a device that can automatically lift the soil at different depths to use an air humidity sensor for detection. Summary of the invention

[0049] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] See also Figure 1-Figure 10As shown, a soil moisture detection device for information water conservancy irrigation is arranged on a support frame 1, and a humidity sensor 2 is provided on the support frame 1 for sensing soil moisture in cooperation with the soil moisture detection device; the soil moisture detection device comprises a soil accumulation shell 3, a soil entry tube 4, a soil discharge tube 5 and a soil lifting mechanism 6; the soil accumulation shell 3 is arranged on the bracket, and the humidity sensor 2 is located in the soil accumulation shell 3; the soil entry tube 4 and the soil discharge tube 5 are symmetrically arranged on both sides of the soil accumulation shell 3, and the axial directions of the soil entry tube 4 and the soil discharge tube 5 are both perpendicular to the ground; the soil lifting mechanism 6 is arranged between the soil entry tube 4 and the soil discharge tube 5, and the soil entry tube 4 and the soil discharge tube 5 are both coordinated with the soil lifting mechanism 6. When the soil enters the soil lifting mechanism 6 along the soil entry tube 4, the soil lifting mechanism 6 is in a state of lifting the soil into the soil accumulation shell 3 to contact the humidity sensor 2.

[0051] When the moisture of the water-irrigated soil is detected, the support frame 1 is placed at the position of the soil to be detected and fixed in the soil. The humidity sensor 2 is installed on the support frame 1, and its output end is facing the soil accumulation shell 3. The soil is drilled out by controlling the soil lifting mechanism 6 and lifted into the soil accumulation shell 3 through the soil entry tube 4. As the soil accumulates in the soil accumulation shell 3, the output end of the humidity sensor 2 finally contacts the soil, thereby sensing the moisture information in the soil, and determining whether the water-irrigated soil in the area has reached a qualified humidity. If the humidity is unqualified, the soil is supplemented with water in time. After the humidity sensor 2 completes the detection, the soil needs to be discharged from the soil accumulation shell 3 to avoid affecting the subsequent soil entry detection. The soil is lowered to the position of the soil discharge tube 5 by the soil lifting mechanism 6, and the soil is then discharged from the soil discharge tube 5.

[0052] See also Figure 3-Figure 6 As shown, the soil accumulation shell 3 is hollow and has openings at both ends. A first extension plate 31 and a second extension plate 32 extend downward on both sides of the lower end of the soil accumulation shell 3, respectively. A gap is left between the first extension plate 31 and the second extension plate 32. An upper end inlet 311 is provided in the upper half of the first extension plate 31, and a lower end outlet 321 is provided in the lower half of the second extension plate 32.

[0053] When soil is piled up in the soil accumulation shell 3, the soil enters the cylinder 4 along the soil and falls into the soil lifting mechanism 6 through the upper inlet 311 on the first extension plate 31. As the soil lifting mechanism 6 lifts the soil upward along the first extension plate 31 and the second extension plate 32, the soil enters the soil accumulation shell 3. The accumulated soil thereby contacts the humidity sensor 2 to complete the sensing of the humidity. When the detection is completed, the soil lifting mechanism 6 moves the soil downward again along the first extension plate 31 and the second extension plate 32. When the soil reaches the lower end outlet 321 of the second extension plate 32, the soil is discharged through the lower end outlet 321 on the second extension plate 32.

[0054] See also Figure 3 and Figure 4 As shown, the soil lifting mechanism 6 is provided with a first spiral auger 61 and a second spiral auger 62. The first spiral auger 61 is coaxially arranged in the soil inlet tube 4, the second spiral auger 62 is coaxially arranged in the soil discharge tube 5, and the lower end of the first spiral auger 61 is also connected to a drill bit 611.

[0055] When the soil lifting mechanism 6 is in the process of lifting the soil, the first spiral auger 61 drives the drill bit 611 to drill a hole in the ground, and the soil is loosened. The first spiral auger 61 lifts the soil in a spiral manner upward along the inner wall of the soil entry tube 4 until the soil passes through the upper end inlet 311 of the first extension plate 31 and falls between the first extension plate 31 and the second extension plate 32. The soil lifting is completed. When the soil is discharged from between the first extension plate 31 and the second extension plate 32, the soil enters the soil discharge tube 5 through the lower end outlet 321 on the second extension plate 32. As the second spiral auger 62 is driven, the soil is finally led out.

[0056] See also Figure 5 and Figure 6 As shown, the soil lifting mechanism 6 is also provided with a sleeve 63, which is sleeved on the first extension plate 31 and the second extension plate 32. The sleeve 63 is connected to the first spiral auger 61 and the second spiral auger 62. The sleeve 63 can move vertically on the soil stacking shell 3. The support frame 1 is provided with a lifting drive 7 for driving the sleeve 63 to move. When the sleeve 63 moves upward, the soil is in a state of being lifted toward the soil stacking shell 3.

[0057] When the soil in the first extension plate 31 and the second extension plate 32 is lifted, due to the setting of the sleeve 63, the sleeve 63 is sleeved on the first extension plate 31 and the second extension plate 32 and can move thereon. As the lifting drive 7 drives the sleeve 63, the sleeve 63 lifts the soil upward and can also drive the soil downward, ensuring that the soil can be detected by the humidity sensor 2 and also ensuring that the soil can be discharged.

[0058] See also Figure 7-Figure 10 As shown, a first lifting cylinder 64 and a second lifting cylinder 65 are respectively provided on both sides of the sleeve 63. The first lifting cylinder 64 is coaxial with the soil inlet cylinder 4, and the second lifting cylinder 65 is coaxial with the soil discharge cylinder 5. The first lifting cylinder 64 and the second lifting cylinder 65 have notches that fit with the first extension plate 31 and the second extension plate 32. The upper ends of the first lifting cylinder 64 and the second lifting cylinder 65 are provided with a rotating driver 612 for driving the first spiral auger 61 and the second spiral auger 62 to rotate.

[0059] When the sleeve 63 moves, since the first lifting cylinder 64 and the second lifting cylinder 65 are respectively provided on both sides of the sleeve 63, and the first lifting cylinder 64 and the soil inlet cylinder 4 are coaxially corresponding, and the second lifting cylinder 65 and the soil discharge cylinder 5 are coaxially corresponding, therefore, in the docking state, the first spiral auger 61 can transport the soil to the first lifting cylinder 64, and since the notch of the first lifting cylinder 64 fits with the first extension plate 31, the soil can fall between the first extension plate 31 and the second extension plate 32 through the upper inlet 311, and the soil therein can also enter the second lifting cylinder 65 through the lower outlet 321 on the second extension plate 32, and in the docking state, the soil is finally discharged through the soil discharge cylinder 5.

[0060] See also Figure 5 and Figure 6 As shown, the bottom of the sleeve 63 has a bottom plate 631 that fits between the first extension plate 31 and the second extension plate 32. When soil enters between the first extension plate 31 and the second extension plate 32 from the upper end inlet 311, the bottom plate 631 is in a state of supporting the soil.

[0061] When the sleeve 63 moves, since the gap between the first extension plate 31 and the second extension plate 32 has a bottom plate 631 connected to the sleeve 63, the bottom plate 631 fills the gap between the first extension plate 31 and the second extension plate 32, so that the soil is supported on the bottom plate 631 and is in the gap between the first extension plate 31 and the second extension plate 32. The movement of the sleeve 63 drives the soil to move until the soil is brought into the soil accumulation shell 3. The sleeve 63 stops moving after contacting the soil accumulation shell 3. Since the gap between the first extension plate 31 and the second extension plate 32 is a narrow channel, the soil will accumulate therein. After the sleeve 63 stops moving, the accumulated soil also contacts the humidity sensor 2, thereby sensing the humidity of the soil.

[0062] See also Figure 3 As shown, a slope block 6311 is provided on the bottom plate 631 and is inclined toward the lower outlet 321 .

[0063] When soil enters the second lifting cylinder 65 from the bottom plate 631 through the lower outlet 321 , since the bottom plate 631 is provided with a slope block 6311 inclined toward the lower outlet 321 , the soil will slide down into the second lifting cylinder 65 along the slope.

[0064] See also Figure 7 As shown, a plurality of heating tubes 632 are provided on the outer side of the sleeve 63 , and a plurality of strip-shaped openings 33 are opened on the soil accumulation shell 3 .

[0065] When the sleeve 63 is completely sleeved on the soil stacking shell 3 and stops moving, the heating tube 632 heats and releases heat, and the heat enters the soil stacking shell 3 through the strip opening 33 on the soil stacking shell 3 to heat the soil therein, causing it to be dried, and the humidity in the space therein is also dried, ensuring that the soil can be discharged smoothly to avoid being attached to the bottom plate 631. The sleeve 63 is sleeved on the soil stacking shell 3, so the soil will not fall out from the strip opening 33.

[0066] See also Figure 1 As shown, the support frame 1 is provided with a plurality of support rods 11 which can be inserted into the soil for fixation.

[0067] When the support frame 1 is placed at the soil position to be detected, since the support frame 1 has a support rod 11 , the support rod 11 is inserted into the soil to ensure the stability of the support frame 1 .

[0068] See also Figure 5 As shown, the output end of the moisture sensor 2 has a probe 21 that is directed straight into the soil accumulation housing 3 .

[0069] When the humidity sensor 2 is in contact with the soil, the probe 21 on the humidity sensor 2 is inserted into the soft soil to complete the detection of the humidity therein.

[0070] The present invention lifts the soil into the soil accumulation shell 3 through the soil lifting mechanism 6, so that the soil is accumulated in the soil accumulation shell 3, prompting the humidity sensor 2 to contact with the soil. Since the soil is in a loose state after being lifted, the humidity sensor 2 will not be damaged due to the hardness of the soil. The protection of the humidity sensor 2 ensures that the humidity sensor 2 can accurately detect the humidity of the soil in an intact state.

[0071] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
