Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and in particular to a soil detection device for facilitating land planning. Background Art

[0002] At present, when conducting land planning, it is generally necessary to test the parameters of the soil in order to facilitate the subsequent planning and use of the land. When testing the soil parameters, a soil parameter testing device is often required. During the testing process, the soil testing device for land planning usually first samples the soil and then performs the test. Some soils contain more water. In order to avoid affecting the test results, a testing device that can heat and dry the soil has now appeared.

[0003] However, although the existing soil detection device with heating and drying soil can use the heating block to heat and dry the soil in its sampling chamber, a large amount of water vapor will be generated during the drying process. Although the water vapor can be discharged through the exhaust valve, a small amount of water vapor will first contact the top wall of the sampling chamber and condense into water droplets and fall back into the soil, thereby reducing the rate of drying the soil. The few soil detection devices that can clean the water droplets on the top wall usually use a driving member such as an electric push rod or a motor to drive a scraper to scrape off the water droplets, but the driving member will generate large vibrations when in use, causing the water droplets to fall due to the vibration before contacting the water droplets, resulting in poor cleaning effect.

[0004] Therefore, we designed a soil detection device which is convenient for land planning to solve the above problems. Summary of the invention

[0009] Furthermore, there are multiple air inlets, which are evenly spaced apart on the front side of the scraper, and the air inlets are located above the partition.

[0017] Compared with the prior art, the beneficial effect of the present invention is: if the setting of the hydrophilic coating affects the normal sliding of water droplets, at this time when the sealing plate is in a vertical state, the scraper can slide down along the guide rod due to gravity, and the scraper can push the water droplets on the surface of the hydrophilic coating to actively slide down, which can improve the effect of cleaning the water droplets.

[0018] Compared with the prior art, the beneficial effect of the present invention is: in order to avoid the problem of water droplets splashing out of the hydrophilic coating and falling into the soil due to the scraper sliding down too fast, air can enter through the air inlet when the scraper falls and blow the cloth cover to bulge, thereby utilizing the wind resistance to slow down the speed of the scraper sliding down, so that the scraper slides down slowly to scrape the water droplets into the water storage box.

[0019] Compared with the prior art, the beneficial effect of the present invention is that by continuing to turn on the motor, the sealing plate can be turned over to 180° as a whole. At this time, by turning on the electromagnet, the electromagnet can be energized to push the rotating plate to rotate upward. In this process, the stopper will push the sealing block to move out of the water outlet, so that a gap can be generated between the sealing block and the water outlet, so that the water collected in the water storage box can slide out of the water storage box along the rotating plate, and finally be discharged out of the material box through the drainage trough, thereby completing the cleaning of the water in the water storage box and avoiding the problem of overflow due to excessive water in the water storage box.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] See also Figure 1-9 The present invention provides a technical solution: a soil detection device for land planning, comprising a detection tube 1, a sampling assembly arranged in the detection tube 1, a material taking box 6 installed outside the detection tube 1, a feeding port 7 provided at the joint of the detection tube 1 and the material taking box 6, and a solenoid valve 8 installed in the feeding port 7, the detection tube 1 is connected with the material taking box 6 through the feeding port 7, a motor 9 is fixedly installed on the top of one side of the material taking box 6, a limiting opening is provided on the top of the material taking box 6, and a rotating shaft 10 is rotatably installed in the limiting opening, A plugging plate 11 is fixedly sleeved on the rotating shaft 10, and the top and bottom of the plugging plate 11 are coated with a hydrophilic coating 12, and a water storage box 13 is fixedly installed at the rear end of the top and the front end of the bottom of the hydrophilic coating 12, and a liquid inlet is opened on one side of the water storage box 13, and a plugging member 14 is rotatably installed in the liquid inlet. A one-way exhaust valve 25 and a one-way air inlet valve 26 are arranged on one side of the material taking box 6, and the one-way air inlet valve 26 is located above the one-way exhaust valve 25. A heating block is arranged in the material taking box 6, and an electric heating wire is embedded in the heating block; The sampling component includes a spiral loading roller 2, which is rotatably installed in the detection cylinder 1. A cavity is opened in the detection cylinder 1, and a motor 3 is embedded in the cavity. The driving end of the motor 3 rotates and extends into the detection cylinder 1 and is transmission-connected to the spiral loading roller 2. A drill bit 4 is fixedly installed at the bottom end of the spiral loading roller 2. A discharge port 5 is opened at the top of one side of the detection cylinder 1, and a handle 35 is fixedly installed on the top of the detection cylinder 1.

[0026] During the specific implementation, the personnel first hold the handle 35, and drive the detection tube 1 and the drill bit 4 to vertically press against the soil to be sampled and tested, then turn on the motor 3 and press the detection tube 1 downward, so that the spiral feeding roller 2 can drive the drill bit 4 to rotate and drill into the soil. During this process, the soil will be discharged through the discharge port 5. When the detection tube 1 extends into the soil to a suitable depth, the solenoid valve 8 is opened to allow the soil to slowly enter the material box 6 through the feed port 7, and the sampling work can be completed; When there is a large amount of water in the soil, in order to avoid affecting the detection results, the heating block can be turned on to allow the electric heating wire to heat the air in the material box 6, thereby drying the moisture in the soil. In this process, water vapor will be generated, and then the water vapor will be discharged through the one-way exhaust valve 25, and a small amount of water vapor will contact the top wall of the material box 6 and form water droplets. At this time, the motor 9 is turned on to allow the rotating shaft 10 to drive the sealing plate 11 to rotate. Since a hydrophilic coating 12 is provided on the sealing plate 11, it is possible to prevent the motor 9 from transmitting vibration to the sealing plate 11 and causing water droplets to fall into the soil before processing. When the sealing plate 11 rotates to 90°, the water droplets slide downward along the sealing plate 11 due to gravity, and finally push the sealing member 14 to rotate and enter the water storage box 13, which can effectively process the water droplets, thereby improving the drying rate of the soil, and can also avoid the problem of water droplets falling into the soil due to vibration when cleaning the water droplets, thereby affecting the drying rate.

[0027] The outer surface of the handle 35 is provided with anti-skid patterns, which can increase the friction between the hand of the person and the handle 35, thereby helping to solve the problem of slipping when the person holds the handle 35.

[0028] See also Figure 1-9 As shown, two fixing plates 27 are symmetrically fixedly installed at the rear end of the top and the front end of the bottom of the hydrophilic coating 12, a guide rod 28 is fixedly installed on one side of the fixing plate 27, and the other end of the guide rod 28 is fixedly installed on the end of one side of the water storage box 13, and a scraper 29 is movably sleeved on the guide rod 28, the scraper 29 is against the outer surface of the hydrophilic coating 12, and the width is equal to that of the water storage box 13.

[0029] In the specific implementation, based on the above implementation, if the setting of the hydrophilic coating 12 affects the normal sliding of water droplets, at this time when the blocking plate 11 is in the vertical state, the scraper 29 can slide down along the guide rod 28 due to gravity, and the scraper 29 can push the water droplets on the surface of the hydrophilic coating 12 to actively slide down, which can improve the effect of cleaning the water droplets.

[0030] See also Figure 1-9 A separator 30 is fixedly installed on the front side of the scraper 29, an air inlet 31 is opened on the front side of the scraper 29, the air inlet 31 passes through the scraper 29 and extends to the rear side of the scraper 29, two connecting members 32 are symmetrically installed on the rear side of the scraper 29, a cloth cover 33 is provided on the connecting member 32, and the cloth cover 33 is located directly behind the air inlet 31.

[0031] In specific implementation, based on the above implementation, in order to avoid the problem of water droplets splashing out of the hydrophilic coating 12 and falling into the soil due to the scraper 29 sliding down too fast, air can enter through the air inlet 31 when the scraper 29 falls and blow the cloth cover 33 to bulge, thereby utilizing wind resistance to slow down the speed at which the scraper 29 slides down slowly, so that the scraper 29 slowly slides down to scrape the water droplets into the water storage box 13.

[0032] There are multiple air inlets 31, which are evenly spaced and arranged on the front side of the scraper 29, and the air inlets 31 are located above the partition 30. The arrangement of multiple air inlets 31 can increase the air intake, so that the cloth cover 33 can be quickly inflated.

[0033] See also Figure 1-9A drainage assembly is also provided in the water storage box 13 for discharging the collected water. The drainage assembly includes a rotating shaft 15, which is fixedly installed in the water storage box 13. A rotating plate 16 is rotatably sleeved on the rotating shaft 15. A gap is left between the rotating plate 16 and the blocking member 14. A stopper 17 is fixedly installed at the end of the top of the rotating plate 16. An electromagnet 18 is fixedly installed on the bottom wall of the water storage box 13. A permanent magnet is fixedly installed at the bottom of the rotating plate 16. The magnetic field directions of the permanent magnet and the electromagnet 18 are opposite. On the contrary, a water outlet 20 is provided on one side of the water storage box 13, a blocking block 24 is slidably connected inside the water outlet 20, the abutment piece 17 cooperates with the blocking block 24 to abut against each other, a slide groove 21 is provided on one side of the water storage box 13, a spring 22 is fixedly installed in the slide groove 21, an L-shaped block 23 is fixedly installed on the other end of the spring 22, and the other end of the L-shaped block 23 is fixedly connected to the blocking block 24, and a drainage groove 34 is provided on one side of the top of the material taking box 6, and the drainage groove 34 is located obliquely below one side of the water storage box 13.

[0034] During specific implementation, on the basis of the above implementation, the motor 9 is continued to be turned on, and the blocking plate 11 can be continued to rotate until the blocking plate 11 is turned over to 180° as a whole. At this time, the electromagnet 18 is turned on and energized. Since the magnetic field of the permanent magnet at the bottom of the rotating plate 16 is opposite to that of the electromagnet 18, the electromagnet 18 can repel and push the rotating plate 16 to rotate upward with the rotating shaft 15 as the axis and generate an inclination. In this process, the stopper 17 will push the blocking block 24 to move out of the water outlet 20, and at the same time, the L-shaped block 23 stretches the spring 22 in the slide groove 21 and moves outward, so that a gap can be generated between the blocking block 24 and the water outlet 20, so that the water collected in the water storage box 13 slides out of the water storage box 13 along the rotating plate 16, and then the water drops fall into the drainage groove 34 and are discharged out of the material collection box 6, so that the water in the water storage box 13 can be cleaned, and the problem of overflow due to excessive water in the water storage box 13 can be avoided.

[0035] See also Figure 1-9 The inner bottom wall of the water storage box 13 is also provided with a battery 19, and the electromagnet 18 is electrically connected to the battery 19. The electromagnet 18 can be normally powered to ensure the normal operation of the electromagnet 18.

[0036] There are two chutes 21, and the two chutes 21 are symmetrically arranged on one side of the water storage box 13. This ensures that the forces on both sides of the blocking block 24 are balanced, thus avoiding the problem of tilting.

[0037] In addition, before use, first connect all electrical appliances on the detection tube 1 except the electromagnet 18 to an external power source, and install a battery pack on the top of the outer side of the detection tube 1 in an area that does not hinder other components. Then, the battery pack is electrically connected to the electrical appliances through a circuit to provide them with electrical energy, thereby ensuring their normal operation. Since the external power source and battery pack are both existing technologies and are not the problems to be solved in the background technology of the specification, they will not be explained in detail in this specification.

[0038] In addition, in order to facilitate the detection of the sampled soil by the soil detection device used in the land planning, we can also install a soil detector inside the material box 6, which can facilitate the detection of the soil. For the soil detector, the soil detector can use sensor technology and Internet of Things technology, and can measure the pH value, conductivity, temperature, humidity and nutrients such as nitrogen, phosphorus and potassium of the soil. Since the soil detector is a prior art and is not a problem to be solved in the background technology of the specification, it will not be explained in detail in this specification.

[0039] It should be noted that for the installation of the motor 3 and the internal components of the material box 6, in order to realize the installation and production operations, we can divide the detection cylinder 1 and the material box 6 into two groups of identical components, and then reasonably install the components inside the detection cylinder 1 and the material box 6 such as the motor 3, the rotating shaft 10, and then weld the two groups of detection cylinders 1 and the material box 6.

[0040] As for the material of the cloth cover 33, we can give priority to using polyester fiber and polyester fiber. Polyester fiber and polyester fiber are usually used in parachutes. They have slight air permeability, can be effectively inflated and have a deceleration effect. Since polyester fiber and polyester fiber are both existing technologies and are not the problem to be solved in the background technology of the specification, they will not be explained in detail in this specification.

[0041] Finally, it should be noted that in order to facilitate the control of the electrical appliances inside the device, we can install a controller on the handle 35 and electrically connect the controller to the electrical appliances, which can facilitate personnel to control the switch and operating status of the electrical appliances. Since the controller is a prior art and is not a problem to be solved in the background technology of the specification, it will not be explained in detail in this specification.

[0042] Working principle: When in use, the operator first holds the handle 35, and drives the detection tube 1 and the drill bit 4 to vertically press against the soil to be sampled and tested, then turns on the motor 3 and presses the detection tube 1 downward, so that the spiral feeding roller 2 drives the drill bit 4 to rotate and drill into the soil. During this process, the soil will be discharged through the discharge port 5. When the detection tube 1 extends into the soil to a suitable depth, the solenoid valve 8 is opened to allow the soil to slowly enter the material box 6 through the feed port 7, and the sampling work can be completed; When there is a large amount of water in the soil, in order to avoid affecting the detection results, the heating block can be turned on to allow the electric heating wire to heat the air in the material box 6, thereby drying the moisture in the soil. In this process, water vapor will be generated, and then the water vapor will be discharged through the one-way exhaust valve 25, and a small amount of water vapor will contact the top wall of the material box 6 and form water droplets. At this time, the motor 9 is turned on to make the rotating shaft 10 drive the sealing plate 11 to rotate. Since the hydrophilic coating 12 is provided on the sealing plate 11, it can be prevented that the motor 9 is transmitted to the sealing plate 11 due to vibration and causes the water droplets to fall into the soil before processing. When the sealing plate 11 rotates to 90°, the water droplets slide downward along the sealing plate 11 due to gravity, and finally push the sealing member 14 to rotate and enter the water storage box 13, which can effectively process the water droplets, thereby improving the drying rate of the soil; In addition, if the setting of the hydrophilic coating 12 affects the normal sliding of water drops, at this time, when the blocking plate 11 is in a vertical state, the scraper 29 can slide down along the guide rod 28 due to gravity, and the scraper 29 can push the water drops on the surface of the hydrophilic coating 12 to slide down actively, which can improve the effect of cleaning water drops; It should be noted that, in order to prevent the scraper 29 from sliding down too fast and causing water droplets to splash out of the hydrophilic coating 12 and fall into the soil, air can enter through the air inlet 31 when the scraper 29 falls and blow the cloth cover 33 to swell, thereby using wind resistance to slow down the speed of the scraper 29, so that the scraper 29 slowly slides down and scrapes the water droplets into the water storage box 13; Finally, continue to turn on the motor 9 and continue to rotate the blocking plate 11 until the blocking plate 11 is turned over to 180° as a whole. At this time, turn on the electromagnet 18 and energize the electromagnet 18. Since the magnetic field of the permanent magnet at the bottom of the rotating plate 16 is opposite to that of the electromagnet 18, the electromagnet 18 can repel each other and push the rotating plate 16 to rotate upward with the rotating shaft 15 as the axis and generate an inclination. During this process, the stopper 17 will push the blocking block 24 to move out of the water outlet 20, and at the same time make the L-shaped block 23 stretch the spring 22 and move outward in the slide groove 21, so that a gap can be generated between the blocking block 24 and the water outlet 20, so that the water collected in the water storage box 13 slides out of the water storage box 13 along the rotating plate 16, and then the water drops fall into the drainage groove 34 and are discharged out of the material box 6, so that the water in the water storage box 13 can be cleaned, and the problem of overflow due to excessive water in the water storage box 13 can be avoided.
