Description

Technical Field

[0001] The utility model relates to the technical field of soil science research, in particular to a screening device for soil detection. Background Art

[0002] Soil testing screening devices are important tools for particle size analysis and screening of soil samples, and are particularly suitable for fields such as agriculture, geological research, and soil science research.

[0003] First, if the replacement of the eccentric block requires complicated disassembly and assembly, it may lead to increased maintenance time and affect the efficiency of the screening device. Operators need more tools or longer time to replace the eccentric block, which is not suitable for quickly adjusting the vibration intensity to adapt to different screening needs.

[0004] Secondly, in devices without a bottom door design, operators need to disassemble most of the device when replacing the eccentric block or checking the status of the equipment, which increases the difficulty of operation and maintenance time.

[0005] Finally, if the placement rack does not have a guide rail or a limit mechanism, the eccentric force may cause the motion trajectory to deviate during the vibration process. The movement of different trajectories may cause uneven distribution of soil particles on the screen, affecting the uniformity of the screening results. Utility Model Content

[0032] In this embodiment, the replacement mechanism includes a base 2, a motor 3, an eccentric block 4, a mounting block 5, a magnetic frame 6 and an auxiliary component. When the eccentric block 4 installed on the motor 3 needs to be replaced, the closing door 7 can be opened at this time, and then the magnetic frame 6 connected to the mounting block 5 is taken down, and the magnetic frame 6 is disengaged from the positioning hole 26 on the eccentric block 4 and the insertion hole 29 on the mounting block 5 in turn. After the magnetic frame 6 is removed, the mounting block 5 can be removed at this time, and the mounting block 5 is twisted to rotate and disengage between the mounting block 5 and the threaded rod 28 on the eccentric block 4. After the mounting block 5 is removed, the eccentric block 4 is taken down at this time, and the eccentric block 4 is removed from the motor 3. At this time, the second positioning block 25 on the motor 3 is disengaged from the second positioning groove 27 of the eccentric block 4. After the eccentric block 4 is removed, a new eccentric block 4 is replaced and then installed according to the above-mentioned disassembly process.

[0033] In this embodiment, the auxiliary component includes a closing door 7, a first spring 8, a fixing frame 9 and a second spring 10. When in use, the closing door 7 is fixedly connected to the main body 1, and then the fixing frame 9 is pulled. At this time, the fixing frame 9 slides in the closing door 7 and compresses the first spring 8, and the fixing frame 9 slides on the second through rod 31. When the fixing frame 9 is out of the card hole 30 on the main body 1, the closing door 7 can be pulled out, and then the eccentric block 4 can be replaced. When the motor 3 fixedly mounted on the base 2 is running, the eccentric block 4 contacts the contact block 21 on the transmission frame 20, thereby pushing the transmission frame 20 to slide up and down in the main body 1. While the transmission frame 20 slides up and down, it squeezes the second spring 10 and slides on the first through rod 23. While the transmission frame 20 slides, the first positioning block 22 on the transmission frame 20 slides in the first positioning groove 24 of the main body 1 at the same time, so that the vibration of the transmission frame 20 is extremely regular up and down vibration.

[0034] In this embodiment, the storage mechanism comprises a placement rack 11, a screening box 12, a rotating rod 13 and a special-shaped bolt 14. When in use, the screening box 12 is installed first. After the screening box 12 is installed into the placement rack 11, the rotating rod 13 is rotated, and then the special-shaped bolt 14 installed on the rotating rod 13 is screwed. As the special-shaped bolt 14 engages with the thread of the rotating rod 13, the extrusion plate 32 on the special-shaped bolt 14 begins to squeeze the screening box 12. While the screening box 12 is squeezed, the rubber pad 16 is also squeezed and the pressure is transmitted to the screening box 12 in the reverse direction. When the extrusion plate 32 on the special-shaped bolt 14 is completely engaged with the special-shaped bolt 14, the pressure After touching the placement frame 11, stop rotating the special-shaped bolt 14, then put the soil on the primary screen 19 of the placement frame 11, and then cover the top cover 18. The drive of the motor 3 drives the eccentric block 4, and the impact of the eccentric block 4 drives the transmission frame 20 to move up and down. At this time, while the transmission frame 20 vibrates, the soil is affected by the primary screen 19 and falls into the screening box 12, and is affected by the fine screen 17 and falls down layer by layer, and finally different soils are separated. At this time, the special-shaped bolt 14 is screwed in the opposite direction, and then the rotating rod 13 is rotated, and the handle 15 is held to pull the screening box 12 out of the placement frame 11, and the soil is poured out and collected.

[0035] Example 2:

[0036] In summary, when in use, when the eccentric block 4 mounted on the motor 3 needs to be replaced, the closing door 7 can be opened at this time. At this time, the closing door 7 is fixedly connected to the main body 1, and then the fixing frame 9 is pulled. At this time, the fixing frame 9 slides in the closing door 7 and compresses the first spring 8, and the fixing frame 9 slides on the second through rod 31 at the same time. When the fixing frame 9 is disengaged from the card hole 30 on the main body 1, the closing door 7 can be pulled out at this time, and then the eccentric block 4 can be replaced. First, take down the magnetic frame 6 connected to the mounting block 5. The magnetic frame 6 is disengaged from the positioning hole 26 on the eccentric block 4 and the insertion hole 29 on the mounting block 5 in turn. When the magnetic frame 6 After removing it, you can now remove the mounting block 5, twist the mounting block 5, and rotate the mounting block 5 and disengage the threaded rod 28 on the eccentric block 4. After removing the mounting block 5, take down the eccentric block 4 and remove the eccentric block 4 from the motor 3. At this time, the second positioning block 25 on the motor 3 is disengaged from the second positioning groove 27 of the eccentric block 4. After the eccentric block 4 is removed, replace it with a new eccentric block 4 and then install it according to the above disassembly process. When the eccentric block 4 is installed and needs to be used, install the filter box 12 on the placement rack 11. After the filter box 12 is installed into the placement rack 11, rotate the rotating rod 13, and then screw it to install it on the rotating rod 13 The special-shaped bolt 14, as the special-shaped bolt 14 engages with the thread of the rotating rod 13, the extrusion plate 32 on the special-shaped bolt 14 begins to squeeze the screening box 12, and while the screening box 12 is squeezed, the rubber pad 16 is also squeezed and the pressure is transmitted to the screening box 12 in the reverse direction. When the extrusion plate 32 on the special-shaped bolt 14 completely contacts the placement frame 11, the rotation of the special-shaped bolt 14 is stopped, and then the soil is placed on the primary screen 19 of the placement frame 11, and then the top cover 18 is covered. The motor 3 fixed on the base 2 is turned, and the eccentric block 4 contacts the contact block 21 on the transmission frame 20, thereby pushing the transmission frame 20 up in the main body 1. The transmission frame 20 slides up and down, squeezing the second spring 10 and sliding on the first through rod 23. While the transmission frame 20 slides, the first positioning block 22 on the transmission frame 20 slides in the first positioning groove 24 of the main body 1 at the same time, so that the vibration of the transmission frame 20 is very regular. The soil is affected by the primary screen 19 and falls into the screening box 12, and is affected by the fine screen 17 and falls down layer by layer, and finally different soils are separated. At this time, the special-shaped bolt 14 is screwed in the opposite direction, and then the rotating rod 13 is rotated, and the handle 15 is held to pull the screening box 12 out of the placement rack 11, and the soil is poured out and collected.
