Description
Technical Field
[0001] This utility model belongs to the field of soil testing technology, specifically a high-efficiency soil testing impurity removal device. Background Technology
[0002] With societal development, people's awareness of environmental protection is constantly increasing, and various environmental testing methods are continuously being enriched and strengthened. Soil testing is one type of environmental testing. Before testing soil indicators, pretreatment is required, including soil impurity removal. The soil sampled for testing may contain impurities such as grass roots and plastic film, thus requiring impurity removal. Impurities in the soil include stones, tree roots, grass roots, leaves, and weeds, which can affect the accuracy and precision of soil testing. Soil testing uses impurity removal devices to remove impurities. When using existing impurity removal devices, if there are clumps of soil, directly screening the soil and impurities can easily cause the clumps of soil to remain on the filter screen, affecting the screening and impurity removal of the soil. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides a highly efficient soil testing and impurity removal device, which solves the problem that when the soil contains clumps, directly screening the soil and impurities can easily cause the clumps of soil to remain on the surface of the filter screen, affecting the screening and impurity removal of the soil.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency soil testing impurity removal device, comprising an impurity removal box, a motor fixedly connected to the top of one side of the impurity removal box, a rotating rod provided with the motor through an output shaft, the two ends of the rotating rod being rotatably connected to the inner wall of the impurity removal box through bearings, stirring blades fixedly installed on the surface of the rotating rod inside the impurity removal box, a mounting base fixedly connected to the top of the impurity removal box on the surface of the stirring blades, multiple crushing tooth plates installed on the inner wall of the mounting base, a through groove opened in the bottom of the mounting base, a movable frame fixedly connected to the middle position of the bottom of the mounting base, the movable frame communicating with the through groove, two electric telescopic rods fixedly connected to one side of the bottom of the mounting base, a common baffle installed at one end of the two electric telescopic rods, the baffle being slidably connected through the inner wall of the movable frame.
[0005] As a further embodiment of this utility model: a collection box is slidably connected through the bottom of the impurity removal box, and a handle is fixedly connected to one side of the collection box.
[0006] As a further embodiment of this utility model: a second motor is fixedly connected to the bottom of the impurity removal box near the first motor. The second motor is provided with a linkage rod through its output shaft, and the two ends of the linkage rod are rotatably connected to the inner wall of the impurity removal box through bearings. Two shaking wheels are fixedly connected to the two ends of the linkage rod inside the impurity removal box.
[0007] As a further embodiment of this utility model: four mounting plates are fixedly connected to both sides of the inner wall of the impurity removal box, and two connecting rods are fixedly connected to the two ends between the two mounting plates on the same side. The same shaking frame is slidably connected through the four connecting rods, and the shaking wheel is in close contact with the bottom of the shaking frame.
[0008] As a further embodiment of this utility model: a filter screen is fixedly connected to the inner wall of the shaking frame, and a movable spring is installed on the surface of each connecting rod located on the upper and lower sides of the shaking frame.
[0009] As a further embodiment of this utility model: a feeding frame is fixedly installed on the top of the impurity removal box, and a debris box is installed on the bottom side of one side of the impurity removal box, with the debris box corresponding to one side of the shaking frame.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This high-efficiency soil testing and impurity removal device consists of a motor, stirring blades, crushing toothed plates, and a rotating rod. The motor drives the rotating rod to rotate inside the impurity removal box via its output shaft. This rotating rod, in turn, drives the stirring blades to rotate. The stirring blades then cause the soil to rotate inside the mounting base, bringing the soil into contact with the crushing toothed plates inside the mounting base. This allows the crushing toothed plates to break up any clumps in the soil, improving the screening and impurity removal effect.
[0012] 2. This high-efficiency soil testing and impurity removal device consists of a second motor, a shaking wheel, a shaking frame, and a filter screen. The second motor drives the linkage rod to rotate via its output shaft, which in turn drives the shaking wheel to rotate at the bottom of the shaking frame. This causes the shaking wheel to continuously compress the shaking frame, which in turn causes the movable springs on both sides of the shaking frame to deform. The elastic force of the deformed springs causes the shaking frame to shake up and down, which in turn causes the shaking frame to drive the filter screen to screen and separate the soil and impurities.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a high-efficiency soil testing and impurity removal device, including an impurity removal box 1, a collection box 13 slidably connected through the bottom of the impurity removal box 1, and a handle 14 fixedly connected to one side of the collection box 13. By setting the handle 14, pulling the handle 14 can drive the collection box 13 to move out of the impurity removal box 1, thereby removing the collection box 13 from the bottom of the impurity removal box 1, which facilitates the transfer of soil in the collection box 13.
[0019] A second motor 15 is fixedly connected to the bottom of the impurity removal box 1 near the motor 2. The second motor 15 is equipped with a linkage rod 16 through its output shaft. The two ends of the linkage rod 16 are rotatably connected to the inner wall of the impurity removal box 1 through bearings. Two shaking wheels 17 are fixedly connected to the two ends of the linkage rod 16 inside the impurity removal box 1. With the second motor 15, the second motor 15 drives the linkage rod 16 to rotate through its output shaft. The linkage rod 16 can drive the shaking wheels 17 to rotate, thereby causing the shaking wheels 17 to drive the shaking frame 20 to shake up and down.
[0020] Four mounting plates 18 are fixedly connected to both sides of the inner wall of the impurity removal box 1. Two connecting rods 19 are fixedly connected to the two ends between two mounting plates 18 on the same side. The same shaking frame 20 is slidably connected through the four connecting rods 19. The shaking wheel 17 is close to the bottom of the shaking frame 20. By setting the connecting rods 19, when the shaking frame 20 shakes up and down, the shaking frame 20 slides outside the connecting rods 19, so that the connecting rods 19 can limit the shaking frame 20, making the movement of the shaking frame 20 more stable.
[0021] A filter screen 21 is fixedly connected to the inner wall of the shaking frame 20. Each connecting rod 19 is equipped with a movable spring 22 on the upper and lower surfaces of the shaking frame 20. By setting the shaking frame 20, when the shaking frame 20 moves up and down, the shaking frame 20 squeezes the movable springs 22 on the upper and lower surfaces of the shaking frame 20, causing the movable springs 22 to deform and generate relative elastic force. The movable springs 22 drive the shaking frame 20 to shake up and down, thereby causing the shaking frame 20 to drive the filter screen 21 to move together, ensuring that the filter screen 21 can screen soil and impurities.
[0022] A feed frame 11 is fixedly installed on the top of the impurity removal box 1, and a waste box 12 is installed on the bottom side of one side of the impurity removal box 1. The waste box 12 is positioned opposite to one side of the shaking frame 20. By setting up the waste box 12, the impurities left by the filter screen 21 move towards the waste box 12 as the shaking frame 20 shakes, until the waste box 12 collects the impurities in a unified manner, which facilitates the processing of the impurities.
[0023] A motor 2 is fixedly connected to the top of one side of the impurity removal box 1. The motor 2 has a rotating rod 3 installed through its output shaft. The two ends of the rotating rod 3 are rotatably connected to the inner wall of the impurity removal box 1 through bearings. A stirring blade 4 is fixedly installed on the surface of the rotating rod 3 inside the impurity removal box 1. A mounting base 5 is fixedly connected to the top of the impurity removal box 1 on the surface of the stirring blade 4. Multiple crushing tooth plates 6 are installed on the inner wall of the mounting base 5. A through groove 7 is opened at the bottom of the mounting base 5. By setting the motor 2, the motor 2 drives the rotating rod 3 to rotate through its output shaft, so that the rotating rod 3 can drive the stirring blade 4 to rotate, thereby allowing the stirring blade 4 to move the soil inside the mounting base 5. The soil can come into contact with the crushing tooth plates 6 to achieve the crushing and processing of the soil.
[0024] A movable frame 8 is fixedly connected to the middle position of the bottom of the mounting base 5. The movable frame 8 is connected to the through groove 7. Two electric telescopic rods 9 are fixedly connected to one side of the bottom of the mounting base 5. The same baffle 10 is installed at one end of the two electric telescopic rods 9. The baffle 10 is slidably connected to the inner wall of the movable frame 8. By setting the electric telescopic rods 9, the electric telescopic rods 9 drive the baffle 10 to move, so that the baffle 10 is inserted into the movable frame 8, thereby blocking the soil at the top of the mounting base 5 and improving the soil breaking effect of the device.
[0025] The working principle of this utility model is as follows:
[0026] In use, soil is poured into the impurity removal box 1 through the feed frame 11. Motor 2 is started, and its output shaft drives the rotating rod 3 to rotate, causing the rotating rod 3 to drive the mixing blades 4 to agitate the soil. This allows the soil to contact the crushing toothed plate 6, where it is crushed by the agitation of the mixing blades 4. After crushing, the electric telescopic rod 9 is started, causing it to retract and move the baffle 10 outwards from the movable frame 8, thus removing the baffle 10's obstruction of the soil. The soil then passes through the channel 7 and the movable frame 8, falling onto the filter screen 21 inside the shaking frame 20. Motor 2 is then started, and its output shaft drives the rotating rod 3 to rotate the rotating rod 3. The soil then passes through the channel 7 and the movable frame 8, falling onto the filter screen 21 inside the shaking frame 20. The output shaft drives the linkage rod 16 to rotate, which in turn drives the shaking wheel 17 to rotate. As the shaking wheel 17 rotates, it continuously squeezes the shaking frame 20, causing the shaking frame 20 to move upward and simultaneously squeeze the movable spring 22. The deformation of the movable spring 22 generates elastic force, causing the shaking frame 20 to shake outside the connecting rod 19. This causes the shaking frame 20 to shake the soil through the filter screen 21, thus allowing the filter screen 21 to filter and separate the soil and impurities. The soil falls into the collection box 13 after being filtered by the filter screen 21, while the impurities are moved out of the impurity removal box 1 and fall into the waste box 12 as the filter screen 21 shakes, thus achieving the impurity removal process of the soil.
