[0001] The invention belongs to the technical field of soil, in particular to a soil bulkiness detection method and detection equipment. Background Art

[0002] Soil bulkiness refers to the looseness of the soil, which is closely related to the porosity, permeability, aeration and water retention capacity of the soil.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 3 As shown, a soil bulkiness detection device according to an embodiment of the present invention comprises a detection seat 1, two support frames 2 are fixedly mounted on the outer surface of the detection seat 1, and electric embedded columns 3 are fixedly mounted at the bottom of the two support frames 2, and the bottom end of the electric embedded column 3 is in a conical shape, and a conveying seat 4 is arranged below the detection seat 1, and a motor and a threaded rod are arranged inside the conveying seat 4, and an embedded cavity 5 is threadedly connected to the outer surface of the threaded rod inside the conveying seat 4, and a detection mechanism is arranged inside the embedded cavity 5, and the detection mechanism is used to detect the soil bulkiness;

[0037] During operation, when the bulkiness of the soil is tested, the test seat 1 is moved to the ground position that needs to be checked, and then the electric embedding column 3 is controlled to move downward so that it is stuck into the soil, so as to fix the entire test seat 1, and then the motor inside the conveying seat 4 is controlled to operate, the motor drives the threaded rod to rotate, and the threaded rod drives the embedding cavity 5 to move downward. The specific connection and rotation method of the motor and the threaded rod inside the conveying seat 4 here is the prior art, and no unnecessary details are given in the embodiments of the present invention. When the embedding cavity 5 is moved to a suitable position inside the soil, the bulkiness of the soil can be tested through the detection mechanism, which not only avoids the problem that the tester needs to take out the soil and then test it, but also can deal with special situations in the soil, and does not require complex and expensive instruments for detection.

[0038] like Figures 2 to 5 As shown, the detection mechanism includes two transverse shafts 501 fixedly mounted on the inner wall of the embedded cavity 5, and the outer circumferential surfaces of the two transverse shafts 501 are fixedly mounted with sector wheels 6, and a ratchet plate 7 is slidably mounted inside the embedded cavity 5, and the ratchet plate 7 is meshedly connected with the sector wheel 6. An electric telescopic column 502 is fixedly mounted inside the embedded cavity 5, and the telescopic end of the electric telescopic column 502 is connected to the upper end surface of the ratchet plate 7. Two deflection frames 8 are clamped on the outer surface of each of the sector wheels 6, and the shape of the deflection frame 8 is arc-shaped. A contact unit is arranged inside the deflection frame 8, and the contact unit is used to extend into the soil and detect the soil;

[0039] During operation, after the embedded cavity 5 moves to a suitable position in the soil, the electric telescopic column 502 is controlled to move downward, so that the electric telescopic column 502 drives the ratchet plate 7 to move downward, and the ratchet plate 7 drives the two sector wheels 6 meshing therewith to rotate, and the sector wheel 6 drives the deflection frame 8 on its outer surface to deflect at a certain angle to one side of the soil, and the deflection frame 8 drives the contact unit to extend into the soil and detect the soil. Two sector wheels 6 and four deflection frames 8 are provided, which can increase the detection range of the soil. After one detection is completed, the contact units inside the four deflection frames 8 are analyzed and compared, and the specific fluffiness of the soil at that location is comprehensively calculated. Compared with only detecting a certain soil location, the detection equipment improves the detection accuracy of the soil.

[0040] like Figures 3 to 7 As shown, the contact unit includes an arc groove 801 opened inside the deflection frame 8, a feeler rod 9 is slidably installed inside the arc groove 801, a friction block 10 is fixedly installed on the outer surface of the feeler rod 9, and a plurality of friction blocks 11 are fixedly installed on the groove wall of the arc groove 801, and the plurality of friction blocks 11 are divided into two groups and are located on both sides of the friction block 10;

[0041] When working, in the initial state, the arrangement of the friction block 10 and the friction block 2 11 is as shown in the attached Figure 6 As shown, the entire deflection frame 8 and the feeler rod 9 are located inside the embedding cavity 5; when the fan-shaped wheel 6 drives the deflection frame 8 and the feeler rod 9 to rotate toward the inside of the soil, the feeler rod 9 will first contact the soil, and the feeler rod 9 will be subjected to the pressure of the soil and move at a certain angle in the arc groove 801. If the hardness of the soil is high, that is, the feeler rod 9 is subjected to a large force, the feeler rod 9 will drive the friction block 10 to break away from the limit of the friction block 2 11 in contact with both sides thereof, and move to the position of the friction block 2 11 at the rear;

[0042] After one test is completed, the ratchet plate 7 is first controlled to return to the initial position, and the ratchet plate 7 drives the fan wheel 6 to return to the initial position, that is, the fan wheel 6 drives the deflection frame 8 and the feeler rod 9 to return to the inside of the embedding cavity 5, and controls the embedding cavity 5 to be away from the soil. At this time, due to the limiting effect of the friction block 2 11, the friction block 1 10 will not move again. Then the deflection frame 8 clamped on the surface of the fan wheel 6 is taken out. At this time, the tester observes the specific moving position of the friction block 10 to indirectly detect the fluffiness of the soil;

[0043] It should be noted that the specific method for indirectly detecting the fluffiness of the soil according to the specific moving position of the friction block 10 is to calculate the specific value of the force exerted on the friction block 10 when it is separated from one of the friction blocks 2 11 based on the pre-set static friction coefficients of the friction block 10 and the friction block 2 11 according to the dynamic friction force and the static friction force, and finally indirectly detect the fluffiness of the soil at that location according to the number of friction blocks 10 separated from the friction blocks 2 11.

[0044] Each of the friction blocks 10 and 11 is made of rubber, and the shapes of the friction blocks 10 and 11 are arc-shaped, and the outer surfaces are provided with protrusions; when working, the friction blocks 10 and 11 are made of rubber, and the friction force of the friction blocks 10 and 11 can be easily calculated, and the shapes of the friction blocks 10 and 11 are arc-shaped, which can facilitate the limiting of the friction block 10 by the friction block 2 11.

[0045] The groove wall of the arc groove 801 is provided with a limiting arc groove 12, and the outer peripheral surface of the touch rod 9 is fixedly installed with a limiting arc plate 13, and the limiting arc plate 13 is slidably set in the limiting arc groove 12, and a roller is rotatably set at the contact position between the limiting arc plate 13 and the limiting arc groove 12; when working, under the mutual limitation of the limiting arc groove 12 and the limiting arc plate 13, the moving position of the touch rod 9 can be limited, so that it is convenient for the touch rod 9 to drive the movement of the friction block 10, so that the friction block 10 is separated from the side of the friction block 2 11, which is conducive to detecting the looseness of the soil.

[0046] The outer surface of the embedding cavity 5 is provided with a circular groove adapted to the feeler rod 9, the bottom of the embedding cavity 5 is in a conical shape, and a classification unit is also provided inside the deflection frame 8, and the classification unit is used to classify soil and stones; when working, the circular groove is provided to facilitate the feeler rod 9 to rotate out of the embedding cavity 5, and under the action of the classification unit, the feeler rod 9 can react when it contacts larger stones.

[0047] like Figures 5 to 9 As shown, the classification unit includes a limit spring 14 fixedly mounted on the inner wall of the arc-shaped groove 801 in the deflection frame 8, and the groove wall of the arc-shaped groove 801 is provided with a plurality of limit slots 15. An elastic telescopic card rod 16 is fixedly mounted at the position corresponding to the limit slot 15 of the touch rod 9, and the shape of the elastic telescopic card rod 16 is adapted to the shape of the limit slot 15. An alarm unit is arranged on the outer surface of the elastic telescopic card rod 16, and the alarm unit is used to alarm when there are large stones in the soil;

[0048] When working, refer to the attached Figure 8 and Fig. 9 As shown, in the initial state, the elastic telescopic card rod 16 is located inside the lowermost limit card slot 15; when the soil looseness is detected and there are no large stones, the alarm unit on the outer surface of the elastic telescopic card rod 16 will not make any sound;

[0049] If there are larger stones in the soil and the feeler rod 9 touches the larger stones during rotation, the force applied to the feeler rod 9 is much greater than the force of the soil, and when the feeler rod 9 continues to rotate following the fan-shaped wheel 6, the feeler rod 9 is subjected to an even greater force. At this time, the feeler rod 9 will drive the elastic telescopic card rod 16 to gradually move away from the lowest limit card slot 15 and cross multiple limit card slots 15. Then the alarm unit will be triggered and connected to the external controller, so that the external controller will light up the alarm light. At this time, the tester can change the test position to avoid the problem of inaccurate soil bulkiness test due to the presence of stones, which is more convenient to use.

[0050] The alarm unit includes a contact 17 fixedly mounted on the outer surface of an elastic telescopic card rod 16, a contact 2 18 is mounted on the inner wall of the arc groove 801 at a position corresponding to the contact 17, a telescopic spring 19 is sleeved on the outer surface of the elastic telescopic card rod 16, and the shape of the side of the elastic telescopic card rod 16 close to the limit card slot 15 is an arc shape;

[0051] When there are large stones in the soil, and the touch rod 9 touches the large stones during the rotation process, the elastic telescopic card rod 16 will be disengaged from all the limit card slots 15, and the elastic telescopic card rod 16 will drive the contact 1 17 to contact the contact 2 18 inside the arc groove 801. The contact 1 17 and the contact 2 18 are in contact. At this time, the external controller will be triggered through the power line, so that the external controller controls the alarm light to light up, so that the tester comes to handle it;

[0052] It should be noted that, under the action of the telescopic spring 19, the elastic telescopic card rod 16 will be tightly stuck in the limit card slot 15. In the rotation stroke of the sector wheel 6, the soil pressure alone is not enough to make the touch rod 9 drive the elastic telescopic card rod 16 to cross all the limit card slots 15. Only when the touch rod 9 is subjected to the pressure of the stone, the pressure is too large, so the elastic telescopic card rod 16 will cross all the limit card slots 15, so it is convenient to detect whether it encounters stones.

[0053] It should also be noted that if the soil pressure is relatively large, when the elastic telescopic card rod 16 detaches from the lowermost limit card slot 15 and enters the next limit card slot 15, the contact 1 17 and the contact 2 18 are not in contact. After one detection is completed, the soil fluffiness can be specifically calculated based on the limit force of the elastic telescopic card rod 16 and the limit card slot 15, the relative friction force between the friction block 10 and the friction block 2 11, and the elastic potential energy of the limit spring 14.

[0054] A plurality of limit slots 15 are equidistantly arranged on the wall of the arc groove 801, and a rubber sleeve is provided at the contact position between the surface of the embedded cavity 5 and the touch rod 9; when working, the rubber sleeve is provided, and when the touch rod 9 returns to the inside of the embedded cavity 5, the rubber sleeve plays a certain barrier role, reducing the problem of soil on the outer surface of the touch rod 9 entering the inside of the embedded cavity 5.

[0055] like Fig.10 As shown, a soil bulkiness detection method, which is applicable to the soil bulkiness detection device described above, comprises the following steps:

[0056] S1. When testing the fluffiness of the soil, the testing base 1 is moved to the indicated ground position, and then the electric embedding column 3 is controlled to move downward so that it is inserted into the soil, so as to fix the entire testing base 1;

[0057] S2. When the deflection frame 8 and the feeler rod 9 are driven by the fan-shaped wheel 6 to rotate toward the inside of the soil, the feeler rod 9 will first contact the soil, and the feeler rod 9 will be subjected to the pressure of the soil and move at a certain angle in the arc groove 801. If the hardness of the soil is high, that is, the feeler rod 9 is subjected to a large force, the feeler rod 9 will drive the friction block 10 to break away from the limit of the friction block 2 11 in contact with it, and move to the position of another group of friction blocks 2 11;

[0058] S3. A specific method for indirectly detecting the bulkiness of the soil according to the specific moving position of the friction block 10 is to calculate the specific value of the force exerted on the friction block 10 when it is separated from one of the friction blocks 2 11 based on the pre-set static friction coefficients of the friction block 10 and the friction block 2 11 according to the dynamic friction force and the static friction force, and finally indirectly detect the bulkiness of the soil at that location according to the number of friction blocks 10 separated from the friction blocks 2 11.

[0059] During operation, when testing the bulkiness of the soil, the testing seat 1 is moved to the indicated ground position, and then the electric embedding column 3 is controlled to move downward so that it is stuck into the soil, so as to fix the entire testing seat 1, and then the motor inside the conveying seat 4 is controlled to operate, the motor drives the threaded rod to rotate, and the threaded rod drives the embedding cavity 5 to move downward. When the embedding cavity 5 moves to a suitable position inside the soil, the bulkiness of the soil can be tested through the testing mechanism, which not only avoids the problem that the tester needs to take out the soil and then test it, but also can deal with special situations in the soil; when the embedding cavity 5 moves to a suitable position in the soil, the control The electric telescopic column 502 is controlled to move downward, so that the electric telescopic column 502 drives the ratchet plate 7 to move downward, and the ratchet plate 7 drives the two sector wheels 6 meshing therewith to rotate, and the sector wheel 6 drives the deflection frame 8 on its outer surface to deflect to one side of the soil at a certain angle, and the deflection frame 8 drives the contact unit to extend into the soil and detect the soil. Two sector wheels 6 and four deflection frames 8 are provided, which can improve the detection range of the soil. After one detection is completed, the contact units inside the four deflection frames 8 are analyzed and compared, and the specific fluffiness of the soil at that location is comprehensively calculated. Compared with only detecting a certain location of the soil, the detection equipment improves the detection accuracy of the soil;

[0060] In the initial state, the arrangement of the friction block 10 and the friction block 2 11 is shown in the attached Figure 6 As shown, the entire deflection frame 8 and the feeler rod 9 are located inside the embedding cavity 5; when the sector wheel 6 drives the deflection frame 8 and the feeler rod 9 to rotate toward the inside of the soil, the feeler rod 9 will first contact the soil, and the feeler rod 9 will be subjected to the pressure of the soil and move at a certain angle in the arc groove 801. If the hardness of the soil is high, that is, the feeler rod 9 is subjected to a large force, the feeler rod 9 will drive the friction block 10 to break away from the limit of the friction block 2 11 in contact with it, and move to the position of another group of friction blocks 2 11;

[0061] After one test is completed, the ratchet plate 7 is first controlled to return to the initial position, and the ratchet plate 7 drives the fan wheel 6 to return to the initial position, that is, the fan wheel 6 drives the deflection frame 8 and the feeler rod 9 to return to the inside of the embedding cavity 5, and controls the embedding cavity 5 to be away from the soil. At this time, due to the limiting effect of the friction block 2 11, the friction block 1 10 will not move again. Then the deflection frame 8 clamped on the surface of the fan wheel 6 is taken out. At this time, the tester observes the specific moving position of the friction block 10 to indirectly detect the fluffiness of the soil;

[0062] See attached Figure 8 and Fig. 9 As shown, in the initial state, the elastic telescopic card rod 16 is located inside the lowermost limit card slot 15; when the soil looseness is detected and there are no large stones, the alarm unit on the outer surface of the elastic telescopic card rod 16 will not make any sound;

[0063] If there are large stones in the soil, and the feeler rod 9 touches the large stones during the rotation process, the force applied to the feeler rod 9 is much greater than the force of the soil, and when the feeler rod 9 continues to rotate with the fan-shaped wheel 6, the feeler rod 9 is subjected to a greater force. At this time, the feeler rod 9 will drive the elastic telescopic card rod 16 to gradually move away from the lowest limit card slot 15 and pass through multiple limit card slots 15. Then the alarm unit will be triggered and connected to the external controller, so that the external controller will light up the alarm light. At this time, the tester can change the test position to avoid the problem of inaccurate soil bulkiness test due to the presence of stones, which is more convenient to use.

[0064] When there are large stones in the soil, and the touch rod 9 touches the large stones during the rotation process, the elastic telescopic card rod 16 will be disengaged from all the limit card slots 15, and the elastic telescopic card rod 16 will drive the contact 1 17 to contact the contact 2 18 inside the arc groove 801. The contact 1 17 and the contact 2 18 are in contact. At this time, the external controller will be triggered through the power line, so that the external controller controls the alarm light to light up, so that the tester comes to handle it;

[0065] It should be noted that, under the action of the telescopic spring 19, the elastic telescopic card rod 16 will be tightly stuck in the limit card slot 15. Within the rotation stroke of the fan-shaped wheel 6, the soil pressure alone is not enough to make the touch rod 9 drive the elastic telescopic card rod 16 to cross all the limit card slots 15. Only after the pressure of the stone, the touch rod 9 is overpressured, so the elastic telescopic card rod 16 will cross all the limit card slots 15, so it is convenient to detect whether it encounters a stone; at the same time, it should be noted that if the soil pressure is relatively large, the elastic telescopic card rod 16 will detach from the bottom limit card slot 15 and enter the next limit card slot 15. At this time, the contact 1 17 and the contact 2 18 are not in contact. After one detection is completed, the soil fluffiness can be specifically calculated based on the limit force of the elastic telescopic card rod 16 and the limit card slot 15, the relative friction between the friction block 10 and the friction block 2 11, and the elastic potential energy of the limit spring 14.
