Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dispersion between mixtures, and particularly relates to a soil mechanical composition determination dispersion device. BACKGROUND

[0002] Soil mechanical composition determination (pycnometer method) is a technology for analyzing soil particle distribution by physical and chemical methods, the core basis of which is the Slichter law, combined with the reading correction and temperature correction of the first pycnometer, to finally determine the soil texture type. In the above determination process, after removing the organic matter of the soil sample, a dispersing agent is added, and the soil particles are fully dispersed by boiling, shaking or grinding method.

[0003] For example, the utility model application number CN2021232958170 discloses a universal multi-position soil mechanical composition determination dispersion device. In the dispersion device, the stirring rod in the dispersion assembly is used to extend into the multiple test tubes arranged on the sample disc, so as to stir the sample in the test tube and improve the effect of mechanical dispersion of the soil suspension.

[0004] However, the above soil mechanical composition determination dispersion device has the following disadvantages when in use: 1. The movement path of the stirring rod is circumferential, and the stirring effect on the soil particles settled at the bottom end of the test tube is not obvious, and it is not easy to fully contact with the dispersing agent; 2. For the traditional method of vertically shaking the soil suspension, it is not easy to control the movement track of the soil suspension, which is easy to cause the soil suspension to overflow, and it is not possible to control the small movement amplitude of the suspension in the vertical direction to achieve uniform dispersion of the soil particles. SUMMARY

[0009] The fixing mechanism mainly plays a role of fixing and clamping the soil suspension containing cylinder; meanwhile, the suspension homogeneous motion track control mechanism controls the soil suspension containing cylinder to do reciprocating motion in the vertical direction according to actual needs, so that the soil suspension can be dispersed in the case of small motion amplitude, and soil suspension overflow can be avoided.

[0010] As preferred, the fixing mechanism comprises a fixing plate, a sliding rod and an upper fixing block.

[0011] The sliding rod is slidingly arranged on the fixing plate, and correspondingly, a sliding groove is arranged on the fixing plate in correspondence.

[0016] The stable suspension mechanism can control the soil suspension containing cylinder to stop moving when the motor does not work, which is beneficial to determining the density of the suspension. Meanwhile, the frequency of the up and down motion of the soil suspension containing cylinder can be maintained stable, and the structure disconnection motion can be avoided.

[0017] As preferred, the stable suspension mechanism further comprises a positioning block, the positioning block is fixed on the connecting plate, and a gap matched with the motion of the locking rod is left between the positioning block and the upper end of the fixing abutment.

[0023] 2. The scheme provided by the present application can more accurately control the amplitude of the dispersion motion of the soil suspension, thereby avoiding the overflow of the soil suspension from the opening of the soil suspension containing cylinder.

[0024] 3.

[0030] The following detailed description of the embodiments of this application, in conjunction with the accompanying drawings, will provide a thorough understanding of how this application uses technical means to solve technical problems and achieve corresponding technical effects, enabling its implementation. The embodiments of this application and the various features within them can be combined with each other without conflict, and all resulting technical solutions are within the protection scope of this application.

[0031] It should be clearly stated that the embodiments described below are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. Example 1

[0032] This embodiment provides a detailed description of the scheme for the soil mechanical composition determination dispersion device:

[0033] like Figures 1-4 As shown, the soil mechanical composition measuring and dispersing device includes a soil suspension container 4, a fixing mechanism, and a suspension homogenization trajectory control mechanism.

[0034] The fixing mechanism includes a lower fixing block 20, on which the soil suspension container 4 is embedded. The suspension homogenization motion trajectory control mechanism includes a folded transmission rod 11, a transmission wheel 12, a trajectory cam 14, a rotating shaft 13, a transmission belt 15, a rotating motor 16, and a mounting plate 29. One end of the folded transmission rod 11 is freely connected to the lower fixing block 20, and the transmission wheel 12 is rotatably mounted on the folded transmission rod 11. The output end of the rotating motor 16 is rotatably connected to the rotating shaft 13 via the transmission belt 15, and the trajectory cam 14 is rotatably connected to the rotating shaft 13 and the transmission wheel 12. The folded transmission rod 11 is rotatably mounted on the mounting plate 29, and the rotating shaft 13 is rotatably mounted on the mounting plate 29. The mounting plate 29 is fixed to the side end of the fixing plate 3. There are multiple trajectory cams 14, each with a different diameter.

[0035] The fixing mechanism comprises a fixing plate 3, a sliding rod 23, an upper fixing block 2 and a spring 28. The sliding rod 23 is slidingly arranged on the fixing plate 3, and correspondingly, a sliding groove is arranged on the fixing plate 3. The upper end of the sliding rod 23 is fixed with the upper fixing block 2, and the lower end of the sliding rod 23 is fixed with the lower fixing block 20. The soil suspension containing cylinder 4 is fixedly arranged between the upper fixing block 2 and the lower fixing block 20. The spring 28 is sleeved on the sliding rod 23, one end of the spring 28 is fixed with the lower fixing block 20, and the other end of the spring 28 is fixed with the fixing plate 3.

[0036] The working principle of the fixing mechanism is as follows:

[0037] As shown in Figure 1 and Figure 4 , the sliding rod 23 is slidingly arranged on the fixing plate 3, and the upper and lower ends of the sliding rod 23 are respectively fixed with the lower fixing block 20 and the upper fixing block 2. The soil suspension containing cylinder 4 is fixedly arranged between the upper fixing block 2 and the lower fixing block 20. When the soil suspension is dispersed and the density of the soil suspension needs to be measured, the hydrometer is arranged in the fixed groove on the upper fixing block 2. Figure 1

[0038] The connecting relationship and working principle of the components of the suspension homogeneous motion trajectory control mechanism are as follows:

[0039] As shown in Figure 1 and Figure 4 , when the suspension needs to be dispersed, the transmission belt 15 is rotated by rotating the motor 16, so that the trajectory cam 14 which rotates synchronously with the transmission belt 15 is rotated. Since the trajectory cam 14 and the transmission wheel 12 are in close contact and transmit power to each other, when the position between the trajectory cam 14 and the transmission wheel 12 is at the high point of the trajectory cam 14, the end of the folding transmission rod 11 moves in the clockwise direction, and correspondingly, when the other end of the folding transmission rod 11 moves in the clockwise direction, the lower fixing block 20 moves downward. Conversely, when the position between the trajectory cam 14 and the transmission wheel 12 is at the low point of the trajectory cam 14, the folding transmission rod 11 drives the lower fixing block 20 to move upward.

[0040] In the above process, since the motion trajectory of the end of the folding transmission rod 11 is arc-shaped, the folding transmission rod 11 is provided with a sliding groove 17 which is adapted to the motion trajectory. The upward or downward component force of the folding transmission rod 11 can drive the lower fixing block 20 to move upward or downward, so as to control the soil suspension containing cylinder 4 to move along the preset upward or downward variable trajectory, thereby facilitating the experimental personnel to design a reasonable dispersion motion trajectory according to the requirements of different soil textures. Example 2

[0041] This embodiment further illustrates the structure of the stable suspension mechanism on the basis of the embodiment 1.

[0042] ​The stable suspension mechanism comprises a fixed abutting piece 10, a locking rod 5, a positioning block 6 and a connecting plate 7. The fixed abutting piece 10 is rotatably installed on the connecting plate 7. The lower end of the fixed abutting piece 10 is provided with an abutting groove embedded with the upper end of the folded transmission rod 11. The upper end of the fixed abutting piece 10 is provided with an insertion groove. Correspondingly, the end of the locking rod 5 is provided with an insertion block matched with the insertion groove. The locking rod 5 is rotatably installed on the connecting plate 7. The connecting plate 7 is installed on the side end of the fixed plate 3. The positioning block 6 is fixed on the connecting plate 7. The gap between the positioning block 6 and the upper end of the fixed abutting piece 10 is matched with the movement of the locking rod 5.

[0043] The connecting relationship and working principle of the components of the stable suspension mechanism are as follows:

[0044] As shown in Figure 1 , when the trajectory cam 14 and the transmission wheel 12 abut against each other, the insertion block at the end of the locking rod 5 is inserted into the insertion groove on the fixed abutting piece 10, so as to avoid the movement of the fixed abutting piece 10, and thus the stable transmission of the trajectory cam 14 and the transmission wheel 12 is ensured. When the trajectory cam 14 is replaced and the position of the end of the folded transmission rod 11 needs to be adjusted, the locking rod 5 is rotated to separate the insertion groove and the insertion block, so as to prevent the end of the folded transmission rod 11 from falling off and control the movement range of the end of the folded transmission rod 11.

[0045] In the above process, when the trajectory cam 14 and the transmission wheel 12 move to the lowest point, the spring 28 is always in the state of being stretched, which causes the folded transmission rod 11 to always have a counterclockwise movement trend. Therefore, as long as the right upper side of the folded transmission rod 11 is positioned, the stable transmission of the trajectory cam 14 and the transmission wheel 12 can be realized.

[0046] In the embodiment, as shown in Figure 3 , the number of insertion grooves is multiple. The circumferential parts of the multiple insertion grooves are on the upper end of the fixed abutting piece 10. The positions of the insertion grooves, the size of the folded transmission rod 11 and the trajectory cam 14 are pre-set. For example, the trajectory cam 14 with a large wheel diameter is matched with the insertion block on the locking rod 5 and the rightmost insertion groove on the fixed abutting piece 10.

[0047] In the embodiment, the end of the locking rod 5 is provided with an operating handle 9.

[0048] In the embodiment, a fixed base 21 and a supporting rod 26 are further included. The end of the fixed plate 3 away from the soil suspension containing cylinder 4 is provided with a sliding rail 24. The supporting rod 26 is slidably installed on the sliding rail 24. The lower end of the supporting rod 26 is fixed with the fixed base 21. The supporting rod 26 and the fixed plate 3 are abutted by the locking bolt 27.

[0049] Because some laboratories have been using the way of fixed time photography to take the readings of hydrometer in different time, the height adjustment between the support rod 26 and the fixed plate 3 can be more suitable for the determination of soil suspension readings in the later stage.
