Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, in particular to a soil extraction device for soil improvement. Background Technique

[0002] Soil is crucial for plant growth as it provides the nutrients, water, and root fixation support necessary for plants. When chemical fertilizers, pesticides are overused and polluted water sources are used for irrigation, the soil will be contaminated, leading to a decline in soil fertility, affecting plant growth, reducing crop yield and quality, and further damaging the food chain and biodiversity. Therefore, it is necessary to extract and detect the soil to improve soil quality.

[0003] Currently, most soil extraction methods involve manually inserting a tubular extractor vertically into the soil, carefully pulling out the extractor from the soil, and sliding out the soil sample by knocking. Although this device improves the convenience of the soil extractor, the extraction efficiency is low, it cannot extract soils at different depths, and when the extracted soil is too wet and the soil adhering to the tube wall cannot be completely removed, it will also affect reuse. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a soil extraction device for soil improvement to simultaneously extract soils at different depths and effectively remove the soil adhering to the extractor.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a soil extraction device for soil improvement, including a barrel body, wherein a plurality of partition plates are fixedly connected in the barrel body from top to bottom. Circular frames are arranged at the upper ends of the partition plates in the barrel body. A plurality of scraping knives are fixedly connected to the frames. A rotating rod is rotatably connected through the middle of the barrel body. A rotating and telescoping mechanism is arranged at the lower end of the rotating rod located below the partition plates.

[0006] Through the above technical solution, multiple partition plates are arranged in the barrel body to extract and analyze soils at different depths. The scraping knives on the frames can effectively scrape off the soil adhering to the inner wall of the barrel body and the upper surfaces of the partition plates. When the sampling depth is reached, the rotating rod drives the rotating and telescoping mechanism to enable the soil to enter the barrel body.

[0007] The rotating and telescoping mechanism includes an annular groove opened at the lower end of the rotating rod directly below the partition plate. A plurality of arc-shaped connecting rods are rotatably connected in the annular groove. Four ends of the lower surfaces of the plurality of partition plates are fixedly connected with slide rails. The slide rails are slidably connected with mounting blocks. One end of the mounting block is fixedly connected with a connecting block. The connecting block is rotatably connected with the arc-shaped connecting rod. The end of the mounting block away from the rotating rod is fixedly connected with a top rod.

[0008] Through the above technical solution, by rotating the rotating rod, several arc-shaped connecting rods slidably connected in the annular groove can drive the mounting block to slide on the slide rail, so that the ejector rod slides out of the square hole. At this time, continue to rotate the barrel body, and soils at different depths can enter the barrel body from the square holes at different levels. After the extraction is completed, rotate the rotating rod, and the ejector rod can slide into the square hole to form a sealing effect, avoiding different depths of soil entering the barrel body at different levels during the lifting process of the barrel body. A plurality of square holes are provided at the four ends of the outer wall of the barrel body from top to bottom, and the ejector rod is slidably connected in the square holes.

[0009] The present utility model is further configured such that a plurality of annular grooves are provided on the outer wall of the barrel body from top to bottom. An adjusting ring is rotatably connected in the annular groove. Circular groove holes are provided on both sides of the annular groove. Connecting columns are fixedly connected to the middle of both sides of the adjusting ring. The connecting columns are slidably connected in the circular groove holes, and one end of the connecting column away from the adjusting ring is fixedly connected to the frame.

[0010] Through the above technical solution, by screwing the adjusting ring, the connecting column can slide in the circular groove hole, thereby driving the inner frame of the barrel body to perform a reciprocating rotational motion.

[0011] The present utility model is further configured such that a plurality of discharge ports are provided on one side of the barrel body from top to bottom. A discharge door is rotatably connected to any one side of the discharge port. A notch is provided in the discharge door and penetrates to one end of the discharge door. A square groove is provided in the middle of the outer wall of the discharge door. A cover plate is rotatably connected to the upper end of the square groove. A push rod is slidably connected in the notch. A positioning block is fixedly connected to one end of the push rod located in the square groove. A compression spring is fixedly connected between one end of the push rod close to the positioning block and the inner wall of the notch. A positioning groove is provided on the side of the discharge port away from the connection with the discharge door.

[0012] Through the above technical solution, the multi-layer discharge doors can control the discharge of soils at different depths in the barrel body. Opening the cover plate can push the positioning block to move, so that the push rod slides out of the positioning groove. At this time, the materials in the barrel body can be discharged from the discharge port. The compression spring can bounce the push rod back after releasing the positioning block.

[0013] The present utility model is further configured such that the bottom of the barrel body is tapered and fixedly connected with a spiral blade.

[0014] Through the above technical solution, the tapered bottom of the barrel body can help the soil extraction device cut into the soil more easily, reduce the resistance, and the spiral blade can push the barrel body into a deeper position in the soil.

[0015] The present utility model is further configured such that a baffle is fixedly connected to the upper end of the barrel body. A sleeve is fixedly connected to the middle of the upper surface of the baffle. A hand wheel is fixedly connected to the upper end of the sleeve.

[0016] Through the above technical solution, rotating the handwheel can make the barrel rotate in the soil. When it reaches a certain depth, the baffle can play a blocking effect, thereby controlling the extraction depth. The handwheel can also be used as a handle, making it easier to carry when the soil extraction device is not in use.

[0017] The present utility model is further configured such that one end of the rotating rod on the outer wall of the barrel is located inside the sleeve, and a knob switch is provided on the upper surface of the sleeve. The knob switch is fixedly connected to the rotating rod.

[0018] Through the above technical solution, the knob switch can make the rotating rod rotate inside the barrel.

[0019] The beneficial effects of the present utility model are as follows:

[0020] 1. Through the rotation and telescoping mechanism of the present utility model, by turning the knob switch, the rotating rod rotates, and several arc-shaped connecting rods slidably connected in the annular groove can drive the mounting block to slide on the slide rail, causing the ejector rod to slide out of the square hole. At this time, continue to rotate the barrel, and soil at different depths can enter the barrel from the square holes at different levels. After the extraction is completed, turn the knob switch to make the rotating rod rotate, causing the ejector rod to slide into the square hole. This setting can extract soil at different depths simultaneously, greatly improving the working efficiency and also avoiding soil at different depths from entering the barrel during the lifting process of the barrel.

[0021] 2. By providing an adjusting ring and a scraper in the present utility model, when turning the adjusting ring, the connecting column can slide in the round groove hole, thereby driving the inner frame of the barrel to perform a reciprocating rotational motion. The scraper on the frame can effectively scrape the soil adhering to the inner wall of the barrel and the upper surface of the partition board, effectively removing the residual soil in the barrel, avoiding cross-contamination between soils when the extraction device is used again, reducing the cleaning difficulty, and extending the service life.

[0031] Please refer to Figures 1-7 , a soil extraction device for soil improvement, including a barrel body 1, in which several partition boards 2 are fixedly connected from top to bottom. Circular frames 11 are arranged at the upper ends of the partition boards 2 in the barrel body 1, and several scrapers 12 are fixedly connected to the frames 11. Several annular grooves 13 are opened on the outer wall of the barrel body 1 from top to bottom. An adjusting ring 14 is rotatably connected in the annular groove 13. Round groove holes 15 are opened on both sides of the annular groove 13. Connecting columns 16 are fixedly connected to the middle parts of both sides of the adjusting ring 14 located in the round groove holes 15. The connecting columns 16 are slidably connected in the round groove holes 15, and the ends of the connecting columns 16 away from the adjusting ring 14 are fixedly connected to the frame 11. A rotating rod 3 is rotatably connected through the middle of the barrel body 1. A rotating and telescoping mechanism is arranged at the lower end of the rotating rod 3 located at the partition board 2. The rotating and telescoping mechanism includes an annular groove 4 opened on the rotating rod 3 directly below the partition board 2. Several arc-shaped connecting rods 5 are rotatably connected in the annular groove 4. Slide rails 8 are fixedly connected to the four ends of the lower surfaces of several partition boards 2. Mounting blocks 6 are slidably connected to the slide rails 8. One end of the mounting block 6 is fixedly connected to a connecting block 9. The connecting block 9 is rotatably connected to the arc-shaped connecting rod 5. The end of the mounting block 6 away from the rotating rod 3 is fixedly connected to an ejector rod 10. Square holes 7 are opened on the four ends of the outer wall of the barrel body 1 from top to bottom. The ejector rod 10 is slidably connected in the square holes 7.

[0032] By turning the adjustment ring 14, the connecting column 16 can slide in the circular groove hole 15, thereby driving the inner frame 11 of the barrel body 1 to perform a reciprocating rotational motion. The scraper 12 on the frame 11 can effectively scrape the soil adhering to the inner wall of the barrel body 1 and the upper surface of the partition plate 2. When the barrel body 1 rotates to a certain depth, by rotating the rotating rod 3, several arc-shaped connecting rods 5 slidingly connected in the annular groove 4 can drive the mounting block 6 to slide on the slide rail 8, so that the ejector rod 10 slides out of the square hole 7. At this time, by continuing to rotate the barrel body 1, the soil at different depths can enter the barrel body 1 from the square holes 7 at different levels. After the extraction is completed, by rotating the rotating rod 3, the ejector rod 10 can slide into the square hole 7 to form a sealing effect, avoiding the soil at different depths from entering the barrel body 1 at different levels during the lifting process of the barrel body 1.

[0033] On one side of the barrel body 1, a plurality of discharge ports 17 are provided from top to bottom. On either side of the discharge port 17, a discharge door 18 is rotatably connected. A notch 19 is provided in the discharge door 18 and penetrates to one end of the discharge door 18. A square groove 20 is provided in the middle of the outer wall of the discharge door 18. A cover plate 21 is rotatably connected to the upper end of the square groove 20. A push rod 22 is slidably connected to the notch 19. A positioning block 23 is fixedly connected to one end of the push rod 22 located in the square groove 20. A compression spring 24 is fixedly connected between the end of the push rod 22 close to the positioning block 23 and the inner wall of the notch 19. A positioning groove 25 is provided on the side of the discharge port 17 away from the connection with the discharge door 18.

[0034] The multi-layer discharge doors 18 can control the discharge of the soil at different depths in the barrel body 1. Opening the cover plate 21 can push the positioning block 23 to move, so that the push rod 22 slides out of the positioning groove 25. At this time, the material in the barrel body 1 can be discharged from the discharge port 17. After releasing the positioning block 23, the compression spring 24 can bounce the push rod 22 back.

[0035] The bottom of the barrel body 1 is conically arranged and fixedly connected with a spiral blade 30. The upper end of the barrel body 1 is fixedly connected with a baffle 26. In the middle of the upper surface of the baffle 26, a sleeve 27 is fixedly connected. The upper end of the sleeve 27 is fixedly connected with a handwheel 28. One end of the rotating rod 3 on the outer wall of the barrel body 1 is located in the sleeve 27. A knob switch 29 is provided on the upper surface of the sleeve 27. The knob switch 29 is fixedly connected with the rotating rod 3.

[0036] The conical arrangement of the bottom of the barrel body 1 can help the soil extraction device cut into the soil more easily, reducing resistance. The spiral blade 30 can push the barrel body 1 deeper into the soil. Rotating the handwheel 28 can make the barrel body 1 rotate in the soil. When reaching a certain depth, the baffle 26 can play a blocking role, thereby controlling the extraction depth. The handwheel 28 can also be used as a handle, making it easier to carry when the soil extraction device is not in use. The knob switch 29 can make the rotating rod 3 rotate in the barrel body 1.

[0037] When the utility model is in use, after the staff place this device at the extraction location, they can rotate the hand wheel 28 to rotate the barrel body 1. The spiral blade 30 at the bottom can push the barrel body 1 into a deeper position in the soil. When reaching the extraction depth, the baffle 26 can block the barrel body 1 from continuing to sink. At this time, turn the knob switch 29, and the rotating rod 3 rotates, so that several arc-shaped connecting rods 5 slidingly connected in the annular groove 4 drive the mounting block 6 to slide on the slide rail 8, making the ejector rod 10 slide out of the square hole 7. At this time, continue to rotate the hand wheel 28, and the soil at different depths can enter the barrel body 1 from the square holes 7 at different levels. After the extraction is completed, turn the knob switch 29 to rotate the rotating rod 3, so that the ejector rod 10 slides into the square hole 7 to form a sealing effect. At this time, the barrel body 1 can be lifted out of the soil. The multi-layer discharge doors 18 can control the discharge of the soil at different depths in the barrel body 1. By turning the adjusting ring 14, the scraper 12 on the frame 11 can effectively scrape the soil adhering to the inner wall of the barrel body 1 and the upper surface of the partition plate 2.

[0038] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
