Description

Technical Field

[0001] The utility model relates to the technical field of soil measurement, in particular to a soil tillage layer depth measuring device. Background Art

[0002] Soil environmental monitoring refers to determining the environmental quality (or degree of pollution) and its changing trends by measuring the representative values ​​of factors that affect soil environmental quality. What we usually call soil monitoring refers to soil environmental monitoring, which generally includes technical contents such as sampling points, sample preparation, analysis methods, result characterization, data statistics and quality evaluation. The rocks on the surface of the earth are gradually destroyed into loose mineral particles of varying sizes (called parent material) through weathering. Soil is formed and evolved under the combined action of multiple soil-forming factors such as parent material, climate, biology, topography, and time. The composition of soil is very complex. Generally speaking, it is composed of three phases: solid, liquid, and gas, including minerals, organic matter produced by the decomposition of plant and animal residues, water, and air.

[0003] After searching, it is found that a soil tillage depth measuring device for tomato planting is disclosed in Chinese patent documents [Announcement No.: CN212363057U]. This soil tillage depth measuring device for tomato planting includes a load-bearing plate and a hydraulic telescopic rod. A storage drawer is provided on the top of the load-bearing plate, and a lithium battery is provided on one side of the storage drawer. A baffle is provided on the top of the storage drawer, and a handle is provided in the middle of the baffle. A detection instrument is provided inside the baffle, and a dashboard is provided on one side of the detection instrument. A data link interface is provided on one side of the dashboard. The patent discloses that the measuring device uses a spiral disc to enable the entire device to detect the depth of the soil layer. At the same time, the depth of drilling can be recorded at all times through a scale to make the measurement result more accurate.

[0004] After searching, it is found that a soil detection device is disclosed in Chinese patent documents [Announcement No.: CN220063449U]. This soil detection device includes a support base, a soil tester is fixedly installed on the support base, a cross frame is fixedly installed on the support base, and a sampling mechanism for sampling soil at different depths is arranged below the cross frame. The detection device disclosed in the patent can scrape the soil on the inner wall of the sampling hole through an oblique blade, and the soil falls from the sampling port into the sampling tube to complete the sampling, and can simultaneously detect and analyze eight groups of soil at different depths.

[0005] However, there are still the following shortcomings in actual use:

[0006] 1. Although the soil can be dropped from the sampling port into the sampling tube to complete the sampling, and eight groups of soils at different depths can be tested and analyzed at the same time, it is inconvenient to take the sampling tube, which makes the soil in the sampling tube fall easily;

[0007] 2. Although the blade can scrape the soil, when the device is not in use, the blade is always exposed to the outside world, which is not only easy to injure the user by mistake, but also easy to wear. Utility Model Content

[0029] The limiting mechanism 17 includes a limiting sleeve 171, a fixing bolt 172 and a slide groove 173. The slide groove 173 is opened at the top of the left side of the fixed tube 8. The surface of the slide groove 173 is slidably connected to the limiting sleeve 171. The right side of the limiting sleeve 171 is threadedly connected with the fixing bolt 172. In this way, after the arc plate 9 is rotated to the surface of the fixed tube 8 to close, the fixing bolt 172 can be loosened, and then the limiting sleeve 171 can be moved downward, so as to limit the fixed tube 8 and the arc plate 9.

[0030] A limit pin 16 is provided through the right side of the top of the vehicle body 1, and the other end of the limit pin 16 cooperates with the top of the movable disk 14. When not in use, the movable disk 14 can be rotated to drive the baffle 15 to rotate backward, thereby shielding the scraper 13 and preventing the scraper 13 from contacting external objects.

[0031] A plurality of limit blocks 18 are fixed on both sides of the inner cavity of the fixing tube 8 , and the limit blocks 18 are made of rubber material, which can increase the friction between the fixing tube 8 and the collecting tube 11 , thereby improving the stability of the vehicle body 1 when it is placed.

[0032] A scale mark 20 is fixed on the surface of the vehicle body 1, and an indicator rod 21 is fixed on the surface of the support plate 4, and the other end of the indicator rod 21 is in contact with the surface of the scale mark 20, so that as the support plate 4 moves, the indicator rod 21 will move together, thereby facilitating the observation of the moving position of the support plate 4.

[0033] A movable groove 19 is provided at the front and rear sides of the left side of the vehicle body 1, and the front and rear sides of one end of the support plate 4 are slidably connected to the inside of the movable groove 19, so that the support plate 4 can be auxiliary supported and convenient for its up and down movement.

[0034] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and this technical solution will not be further elaborated.

[0035] Working principle: When in use, the device can be moved to the desired position, and then when measuring, the first motor 2 can be started to drive the screw 3 to rotate, and at the same time drive the support plate 4, the second motor 5 and the auger rod 6 to move together. During the movement, the second motor 5 can be started to drive the auger rod 6 to rotate, so as to drill the land. After drilling to a certain depth, the device is moved again so that the bottom of the fixed pipe 8 is located above the drill hole, and then the electric push rod 7 is started to drive the fixed pipe 8 and the arc plate 9 to move downward to the desired position, and the fixed pipe 8 on one side is moved upward. The scraper 13 is fitted with the inner wall of the drilled hole, and then the electric push rod 7 can be restarted to drive the fixed tube 8 and the curved plate 9 back to the starting position. When the fixed tube 8 moves upward, it will drive the scraper 13 to scrape the soil, so that the scraped soil can enter the interior of the collecting tube 11 through the through hole 12. Then the limit on the curved plate 9 can be cancelled by the limiting mechanism 17, and the curved plate 9 can be opened, and finally the collecting tube 11 can be taken out. When the device is not in use, the limit on the movable disk 14 by the limiting pin 16 can be cancelled, and then the baffle 15 can be rotated to shield and protect the scraper 13.
