Description

Technical Field

[0001] The present application relates to the technical field of dispersion between mixtures, and in particular to a dispersion device for measuring soil mechanical composition. Background Art

[0002] Soil mechanical composition determination (hydrometer method) is a technology that analyzes soil particle distribution through physical and chemical methods. Its core basis is Stokes' law, combined with the reading correction and temperature correction of the type A hydrometer, to ultimately determine the soil texture type. In the above determination process, it is necessary to remove organic matter from the soil sample, add a dispersant, and fully disperse the soil particles by boiling, shaking or grinding.

[0003] For example, Chinese utility model application number CN2021232958170 discloses a universal multi-position soil mechanical composition determination dispersion device, in which a stirring rod in a dispersion assembly is provided to extend into a plurality of test cylinders provided on a sample tray, thereby stirring the samples in the test cylinders and improving the mechanical dispersion effect of the soil suspension.

[0004] However, the above-mentioned soil mechanical composition determination and dispersion device has the following disadvantages when used: 1. The movement path of the stirring rod is circumferential, and the stirring effect on the soil particles after the bottom of the test tube is not obvious, and it is not easy to fully contact with the dispersant; 2. For the traditional method of shaking the soil suspension up and down in the vertical direction, it is not easy to control the movement trajectory of the soil suspension, which may easily cause the soil suspension to overflow, and it is impossible to control the suspension in a small vertical movement amplitude to achieve uniform dispersion of the soil particles. Summary of the invention

[0005] The invention provides a soil mechanical composition determination and dispersion device, which has the advantages of realizing rapid dispersion of suspension by composite motion trajectory control and preventing liquid overflow in combination with a self-locking stable structure.

[0006] The objective of the present invention is achieved through the following technical solutions: A soil mechanical composition determination and dispersion device, comprising a soil suspension containing cylinder, a fixing mechanism and a suspension homogenization motion trajectory control mechanism; The fixing mechanism comprises a lower fixing block, and the soil suspension containing tube is embedded in the lower fixing block; the suspension homogenization motion trajectory control mechanism comprises a folding transmission rod, a conduction wheel, a trajectory cam, a rotating shaft, a transmission belt and a rotating motor; one end of the folding transmission rod is freely connected to the lower fixing block, and the conduction wheel is rotatably mounted on the folding transmission rod; the output end of the rotating motor is rotatably connected to the rotating shaft through a transmission belt, the trajectory cam is rotatably connected to the rotating shaft, and the trajectory cam is transmission-connected to the conduction wheel.

[0007] Among them, the fixing mechanism mainly plays the role of fixing and clamping the soil suspension containing tube; at the same time, the suspension homogenization motion trajectory control mechanism controls the soil suspension containing tube to make reciprocating motion in the vertical direction according to actual needs, and can control the soil suspension containing tube to achieve dispersion of the soil suspension when the motion amplitude is small, thereby avoiding overflow of the soil suspension.

[0008] Preferably, the fixing mechanism comprises a fixing plate, a sliding rod and an upper fixing block; The sliding rod is slidably arranged on the fixed plate, and correspondingly, a sliding groove is correspondingly arranged on the fixed plate, the upper end of the sliding rod is fixed to the upper fixed block, the lower end of the sliding rod is fixed to the lower fixed block, and the soil suspension containing tube fixing clamp is arranged between the upper fixed block and the lower fixed block.

[0009] Preferably, the suspension homogenization motion trajectory control mechanism further comprises a mounting plate, the folding transmission rod is rotatably mounted on the mounting plate, the rotating shaft is rotatably mounted on the mounting plate, and the mounting plate is fixed to the side end of the fixed plate.

[0010] Preferably, there are multiple track cams, and the diameters of the multiple track cams are different.

[0011] Preferably, the fixing mechanism further comprises a spring, wherein the spring is sleeved on the sliding rod, one end of the spring is fixed to the lower fixing block, and the other end of the spring is fixed to the fixing plate.

[0012] Preferably, the soil mechanical composition determination and dispersion device also includes a stable suspension mechanism, which includes a fixed abutment, a locking rod and a connecting plate; the fixed abutment is rotatably mounted on the connecting plate, the lower end of the fixed abutment is provided with a locking groove that is adapted to be embedded in the upper end of the folding transmission rod, the upper end of the fixed abutment is provided with a slot, and accordingly, the end of the locking rod is provided with an insert block that is adapted to the slot, the locking rod is rotatably mounted on the connecting plate, and the connecting plate is mounted on the side end of the fixed plate.

[0013] Among them, the stable suspension mechanism can control the soil suspension container to stop moving when the motor is not working, which is conducive to measuring the density of the suspension. At the same time, it can maintain the frequency of the soil suspension container moving up and down stable to avoid structural disjointed movement.

[0014] Preferably, the stable suspension mechanism further comprises a positioning block, which is fixed on the connecting plate, and a gap is left between the positioning block and the upper end of the fixed abutment plate to accommodate the movement of the locking rod.

[0015] Preferably, there are multiple slots, and the circumferential portions of the multiple slots are at the upper end of the fixed abutment.

A rotating motor is used to drive the rotating shaft through a transmission belt. Multiple track cams with different diameters are set on the shaft. The rotational motion is converted into a composite track motion with a vertical component through the engagement of the cam and the transmission wheel. This is conducive to driving the irregular movement of the suspension in the soil suspension container, so that the suspension and dispersant are evenly mixed, which is conducive to the dispersion of soil particles.

[0019] 2. The solution provided in this application is aimed at directly controlling the vertical movement of the soil suspension, and can more accurately control the amplitude of the dispersion movement of the soil suspension, thereby preventing the soil suspension from overflowing from the opening of the soil suspension container.

[0020] 3. By controlling the movement amplitude of one end of the folding transmission rod, the movement amplitude of the other end can be controlled, thereby controlling the amplitude of the vertical movement of the soil suspension. If the motion trajectory needs to be customized, the circumference of the trajectory cam can be changed to customize the dispersion movement exclusive to the soil suspension, which is more suitable for soil structures of different textures.

DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present application applies technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of the present application and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the protection scope of the present application.

[0024] It should be clear that the embodiments described below are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by technicians in the relevant field without making creative work are within the scope of protection of the present application. Example 1

[0025] This embodiment describes in detail the scheme of the soil mechanical composition determination dispersion device: like Figure 1-4 As shown, the soil mechanical composition determination and dispersion device comprises a soil suspension receiving tube 4, a fixing mechanism and a suspension homogenization motion trajectory control mechanism; The fixing mechanism includes a lower fixing block 20, and the soil suspension containing tube 4 is embedded in the lower fixing block 20; the suspension homogenization motion trajectory control mechanism includes a folding 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 folding transmission rod 11 is freely connected to the lower fixing block 20, and the transmission wheel 12 is rotatably mounted on the folding transmission rod 11; the output end of the rotating motor 16 is rotatably connected to the rotating shaft 13 through the transmission belt 15, the trajectory cam 14 is rotatably connected to the rotating shaft 13, and the trajectory cam 14 is transmission-connected to the transmission wheel 12. The folding transmission rod 11 is rotatably mounted on the mounting plate 29, the rotating shaft 13 is rotatably mounted on the mounting plate 29, and the mounting plate 29 is fixed to the side end of the fixing plate 3. There are multiple trajectory cams 14, and the diameters of the multiple trajectory cams 14 are different.

[0026] The fixing mechanism includes a fixing plate 3, a sliding rod 23, an upper fixing block 2 and a spring 28; the sliding rod 23 is slidably arranged on the fixing plate 3, and correspondingly, a sliding groove is correspondingly arranged on the fixing plate 3, the upper end of the sliding rod 23 is fixed to the upper fixing block 2, the lower end of the sliding rod 23 is fixed to the lower fixing block 20, and the soil suspension containing tube 4 is fixedly clamped 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 to the lower fixing block 20, and the other end is fixed to the fixing plate 3.

[0027] The working principle of the fixing mechanism is: like Figure 1 and Figure 4As shown, the sliding rod 23 is slidably mounted on the fixed plate 3, and the upper and lower ends of the sliding rod 23 are fixed to the lower fixed block 20 and the upper fixed block 2 respectively. The soil suspension container 4 is fixedly mounted between the upper fixed block 2 and the lower fixed block 20. After the soil suspension is dispersed, when the density of the soil suspension needs to be measured, the hydrometer is placed in the fixed groove on the upper fixed block 2 ( Figure 1 as shown).

[0028] The connection relationship and working principle of the components of the suspension homogenization motion trajectory control mechanism are as follows: like Figure 1 and Figure 4 As shown, when the suspension dispersion work is required, the transmission belt 15 is driven to rotate by rotating the motor 16, thereby driving the track cam 14 that rotates synchronously therewith to rotate. Since the track cam 14 and the transmission wheel 12 are in close contact with each other for transmission, when the position between the track cam 14 and the transmission wheel 12 is at the high point of the track cam 14, the end of the folding transmission rod 11 will be driven to move in the clockwise direction. Correspondingly, when the other end of the folding transmission rod 11 moves clockwise, the lower fixed block 20 will be driven to move downward. On the contrary, when the position between the track cam 14 and the transmission wheel 12 is at the low point of the track cam 14, the folding transmission rod 11 drives the lower fixed block 20 to move upward.

[0029] In the above process, since the motion trajectory of the end of the folding transmission rod 11 is arc-shaped, a sliding groove 17 adapted to its motion trajectory is reserved on the folding transmission rod 11, and its upward or downward component force can drive the lower fixed block 20 to move up and down, thereby controlling the soil suspension containing tube 4 to move along the preset motion trajectory. The variable trajectory up and down is beneficial for the experimenter to design a reasonable dispersion motion trajectory according to the requirements of different soil textures. Example 2

[0030] This embodiment further describes the structure of the stable suspension mechanism based on the embodiment 1: The stable suspension mechanism includes a fixed abutment 10, a locking rod 5, a positioning block 6 and a connecting plate 7; the fixed abutment 10 is rotatably mounted on the connecting plate 7, the lower end of the fixed abutment 10 is provided with a locking groove adapted to be embedded in the upper end of the folding transmission rod 11, the upper end of the fixed abutment 10 is provided with a slot, and correspondingly, the end of the locking rod 5 is provided with an insert block adapted to the slot, the locking rod 5 is rotatably mounted on the connecting plate 7, and the connecting plate 7 is mounted on the side end of the fixed plate 3. The positioning block 6 is fixed on the connecting plate 7, and a gap is left between the positioning block 6 and the upper end of the fixed abutment 10 to adapt to the movement of the locking rod 5.

[0031] The connection relationship and working principle of the components of the stable suspension mechanism are as follows: like Figure 1As shown, after the track cam 14 and the transmission wheel 12 are pressed against each other for transmission, the plug block at the end of the locking rod 5 is correspondingly inserted into the slot on the fixed abutment 10, thereby preventing the fixed abutment 10 from moving, thereby making the track cam 14 and the transmission wheel 12 stable during transmission. When the track cam 14 is replaced and the end position of the folding transmission rod 11 needs to be readjusted, the locking rod 5 can be rotated to disengage the slot and the plug block, thereby achieving the function of preventing falling off and controlling the movement amplitude of the end of the folding transmission rod 11.

[0032] In the above process, when the track cam 14 and the transmission wheel 12 move to the lowest point, the spring 28 is always in a stretched state, causing the folding transmission rod 11 to always have a tendency to move counterclockwise. Therefore, as long as the upper right side of the folding transmission rod 11 is positioned, stable transmission of the track cam 14 and the transmission wheel 12 can be achieved.

[0033] In this embodiment, Figure 3 As shown, there are multiple slots, and the circumference of multiple slots is at the upper end of the fixed abutment 10. The position of the slot, the size of the folding transmission rod 11, and the track cam 14 are pre-set. For example, the track cam 14 with a large wheel diameter corresponds to the plug block on the locking rod 5 and the rightmost slot on the fixed abutment 10 for plugging and fixing.

[0034] In this embodiment, an operating handle 9 is provided at the end of the locking rod 5 .

[0035] This embodiment also includes a fixed base 21 and a support rod 26. A slide rail 24 is provided at one end of the fixed plate 3 facing away from the soil suspension containing tube 4. The support rod 26 is slidably installed on the slide rail 24. The lower end of the support rod 26 is fixed to the fixed base 21, and the support rod 26 and the fixed plate 3 are tightened by a locking bolt 27.

[0036] Since some laboratories have adopted the method of timed photography to take pictures of the hydrometer readings at different time ends during the soil suspension measurement process, the height adjustment between the support rod 26 and the fixed plate 3 can be more suitable for the later measurement of the soil suspension readings.
