Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, an embodiment of the present invention provides a rapid soil sieve for soil testing, comprising:

[0034] Vibration machine 1 and lower positioning ring 2 located at the center of the upper end of vibration machine 1;

[0035] The lower positioning ring 2 is provided with fixed vertical rods 3 on both the left and right sides, and the two fixed vertical rods 3 are fixedly connected to the upper end of the vibrator 1. The upper fixed pressure plate 4 is sleeved on the top of the two fixed vertical rods 3 and fixedly connected by bolts. The upper positioning ring 5 is provided at the lower end of the upper fixed pressure plate 4.

[0036] A large particle collection chamber 6 is snapped into the upper end of the lower positioning ring 2. A sieve barrel 7 is connected to the upper end of the large particle collection chamber 6. The large particle collection chamber 6 and the sieve barrel 7 are used for fixation. A soil sampling port 8 is connected to the rear end of the large particle collection chamber 6. A soil sampling drawer 9 is snapped into the large particle collection chamber 6 and the soil sampling port 8. The soil sampling drawer 9 can be pulled in and out from the rear opening of the soil sampling port 8. Larger soil particles and debris are removed through the soil sampling port 8 and the soil sampling drawer 9. A soil guide plate 10 is fixedly connected to the right side of the upper end of the sieve barrel 7. This plate is used to collect the soil to be sieved and guide the soil to be sieved from the top of the spiral sieve mesh 12. A vertically downward connecting central column 11 is fixedly connected to the left end of the soil guide plate 10. The connecting central column 11 passes through the center of the sieve barrel 7 and is used to fix the spiral sieve mesh 12 and the collection... A spiral sieve 12 and a collection plate 14 are fixedly connected between the central column 11 and the screening barrel 7. The spiral sieve 12 is positioned higher than the collection plate 14. The spiral sieve 12 is used for soil screening, and the collection plate 14 is used to collect the screened soil particles. Multiple soil-breaking cones 13 are fixedly connected to the upper spiral surface of the spiral sieve 12 for breaking up the aggregated soil. Multiple vertically arranged partition plates 15 separate multiple collection chambers between the spiral sieve 12 and the collection plate 14. Soil particles of different sizes are separated and discharged through the multiple collection chambers. The ends of the multiple collection chambers away from the central column 11 are connected to a spiral soil discharge trough 16, which is opened on the cylindrical outer wall of the screening barrel 7. The screened soil is discharged through the spiral soil discharge trough 16.

[0037] The mesh size of the spiral screening net 12 gradually increases from top to bottom, and the lowermost end is connected to the inside of the large particle collecting chamber 6, which can first screen smaller soil particles and then screen larger soil particles, preventing smaller soil particles from mixing with larger soil particles. The multiple soil breaking cones 13 are evenly distributed on the upper spiral outer wall of the spiral screening net 12 in a spiral downward direction, and are arranged in a triangular shape with the sharp angle pointing upward, making the soil breaking cones 13 more sharp and easier to break up the accumulated soil.

[0038] The upper end of the spiral outer wall of the collecting plate 14 is higher on the side close to the connecting central column 11 than on the side close to the screening barrel 7, and is connected to the outside through the spiral soil outlet groove 16, allowing the soil particles to more easily slide to the spiral soil outlet groove 16, enabling the soil to be separated and discharged simultaneously.

[0039] The multiple partition plates 15 are spirally downwardly distributed between the spiral screening net 12 and the collecting plate 14, and have equal interval angles, which can uniformly separate soil particles of different sizes.

The multiple collection chambers are connected to the collection boxes 18 through the two spiral clamping grooves 17 on the side away from the connecting central column 11. The lower end of each collection box 18 is provided with a positioning block 19, which is fixedly connected to the cylindrical outer wall of the screening barrel 7. The spiral clamping grooves 17 and the positioning blocks 19 are used to position the collection boxes 18, so that the collection boxes 18 can correspond to the collection chambers one by one. The upper end of each positioning block 19 is internally slidably connected to a fixed sliding pin 20, and the lower end of each fixed sliding pin 20 is provided with a fixed spring 21. The fixed spring 21 is located inside the positioning block 19. The inside of the collection box 18 and the positioning block 19 away from the screening barrel 7 is provided with a label slot 22. The lower end of each collection box 18 is fixedly connected to a positioning clamp head 23, which is connected to the upper end of the positioning block 19. The fixed clamp slot in the lower end of the positioning clamp head 23 and the positioning block 19 are fixed by the fixed sliding pin 20 and the fixed spring 21, so that the fixed sliding pin 20 can be clamped into the fixed clamp slot to position and fix the collection box 18 and the positioning block 19.

[0041] The multiple collection boxes 18 are spirally distributed outside the screening barrel 7, and the adjacent two collection boxes 18 can be tightly attached to each other and can completely block the spiral soil outlet groove 16. The collection boxes 18 can be tightly attached to the outside of the screening barrel 7 and can prevent soil particles from leaking out.

[0042] The soil collecting box 18 is positioned with the positioning block 19 and the positioning chuck 23, and the opening of the soil collecting box 18 close to one end of the sieve barrel 7 is larger than the opening of the sieve barrel 7 away from the connecting center column 11, so that the soil particles of different sizes are prevented from mixing, and the soil particles are not hindered from entering the soil collecting box 18.

[0043] The top end of the fixed sliding pin 20 and the fixed clamping groove in the lower end of the positioning chuck 23 are both in a semispherical shape, the fixed sliding pin 20 can be smoothly clamped into and out of the fixed clamping groove, the installation and removal of the soil collecting box 18 are more convenient, and the detection efficiency is improved.

[0044] The digital labels are pasted in the label slot 22, the numbers of the label slot 22 in the outer wall of the soil collecting box 18 and the positioning block 19 outside the same sieve chamber are the same, the size of the soil particles can be analyzed through the order of the numbers, the soil particles of different sizes are prevented from being confused, the installation and removal of the soil collecting box 18 are more convenient, and the detection efficiency is improved.

[0045] A soil detection rapid soil screening device usage mode, comprising:

[0046] Installation: the same digital labels are pasted in the label slot 22 in the corresponding soil collecting box 18 and positioning block 19 in order, the multiple soil collecting boxes 18 are installed outside the sieve barrel 7 through the label slot 22 in the soil collecting box 18 and the positioning block 19 in order, then the lower end of the large particle collecting chamber 6 is clamped into the lower positioning ring 2, and finally the upper end of the sieve barrel 7 is fixed through the upper fixed pressing plate 4 and the upper positioning ring 5, and the installation is completed.

[0047] Detection: the soil to be detected is poured onto the upper end of the soil guiding plate 10 and the spiral screening net 12, the vibration machine 1 is started, the soil is continuously screened, the soil particles are leaked onto the upper end of the collecting plate 14 through the spiral screening net 12, are separated through the multiple separation plates 15, are guided out of the spiral soil outlet slot 16, are collected into the soil collecting box 18, and finally the soil particles in the soil collecting box 18 are taken out for soil detection and analysis.

[0048] The working principle is as follows:

[0049] The multiple soil collecting boxes 18 are installed in sequence to the outside of the screening barrel 7 by corresponding to the numbers inside the brand slot 22, and the lower end of the large particle collecting chamber 6 is fixed by the lower positioning ring 2, and the upper end of the screening barrel 7 is fixed by the upper fixing plate 4 and the upper positioning ring 5, so that the screener is installed, and then the soil to be detected is poured into the upper end of the screening barrel 7, the vibration machine 1 is started, and the soil is screened and added through the upper end of the screening barrel 7, so that the soil can be continuously screened, and different size soil particles are leaked onto the upper end of the collecting plate 14 through the spiral screening net 12, and are separated by the multiple separation plates 15 and guided to the spiral soil outlet slot 16, and then are guided into the inside of the soil collecting box 18 for collection, and finally the soil collecting box 18 is removed for soil detection and analysis;

[0050] In this process, since the mesh size of the spiral screening net 12 gradually increases from top to bottom, the soil can be screened from small to large in the rolling process, so that the small soil particles cannot be mixed with the large soil particles and cannot be separated again, so that the soil screening is more thorough, and the spiral screening net 12 can change the same layer screening into spiral downward screening, so that the soil can be continuously screened, that is, the soil can be added while being screened, and the soil screening efficiency can be effectively improved;

[0051] In addition, the screened soil particles can be guided out through the multiple separation chambers separated by the multiple separation plates 15 and the spiral soil outlet slot 16, and collected and taken out through the multiple soil collecting boxes 18 corresponding to the multiple separation chambers one by one, which is more convenient to take out, and the soil collecting box 18 is positioned between the separation chambers through the positioning block 19, and is fixed through the fixed sliding pin 20 and the positioning clamp 23, which is convenient to install and take down, and can be sorted through the multiple brand slots 22, so that the screened soil particles can be sorted and detected according to size, which can prevent soil particles from being confused and improve the soil detection efficiency.
