Description

Technical Field

[0001] This application relates to the technical field of engineering detection, and in particular to an infrared drying oven for measuring soil moisture content. Background Art

[0002] Soil water content is the amount of water contained in the soil. Generally, it refers to the absolute water content of the soil, that is, the number of grams of water contained in 100 g of dried soil, also known as soil moisture content. Soil moisture content reflects the dry-wet state of the soil. Changes in moisture content can cause changes in the mechanical properties of the soil. Through the moisture content, indicators such as dry density, void ratio, and saturation of the soil can be calculated. It is an important basis for controlling the construction quality of geotechnical buildings and subgrade construction and plays an important role in engineering construction.

[0003] In the prior art, the test process for soil water content is to place the soil sample in a container, and then place the container on the support plate of the far-infrared drying oven for heating. After heating for a period of time, the container is taken out and quickly sealed. The sealed container is placed in a thermostat until the mass no longer changes, and the soil water content can be obtained by calculating the percentage of mass loss.

[0004] However, when the container containing the soil sample is placed on the support plate of the far-infrared drying oven, there is no limit, so that when the support plate is pulled out of the far-infrared drying oven, the container may slip or tilt, resulting in dropping. Utility Model Content

[0005] In order to limit the container for holding the soil sample, this application provides an infrared drying oven for measuring soil moisture content.

[0006] An infrared drying oven for measuring soil moisture content provided by this application adopts the following technical solutions:

[0007] An infrared drying oven for measuring soil moisture content, comprising:

[0008] A far-infrared drying oven;

[0009] A support plate, slidably arranged in the far-infrared drying oven;

[0010] A clamping part, slidably arranged on the support plate, and a plurality of clamping parts are provided. A clamping space for placing the soil sample container is formed between adjacent clamping parts;

[0011] A turntable, rotatably arranged on the support plate. An arc-shaped groove is formed on the turntable. The clamping part is slidably connected to the arc-shaped groove, and the arc-shaped groove extends from the outer circle of the turntable to the center of the circle;

[0012] A driving component, used to drive the turntable to rotate, so that the clamping parts move in a direction of approaching each other.

[0013] By adopting the above technical solution, the support plate is pulled out from the far-infrared drying oven, and then the clamping part is opened, and the container containing the soil sample is placed between the clamping parts. The driving component drives the turntable to rotate, so that the turntable drives the clamping part to slide along the arc-shaped groove, thereby pushing the clamping part in the direction of approaching each other, so that the clamping part clamps on the container, realizing the clamping and positioning of the container and ensuring the stability of the container on the support plate.

[0014] Optionally, the driving component includes a gear ring fixedly arranged on the turntable, a rack slidably arranged on the support plate, and an elastic member for pushing the rack to move; the gear ring and the rack are meshed.

[0015] By adopting the above technical solution, the elastic member pushes the rack to move, the rack drives the gear ring to rotate, the gear ring drives the turntable to rotate, and the turntable drives the clamping parts to gather in the direction of approaching each other, thereby realizing the clamping of the container.

[0016] Optionally, the moving track of the rack and the moving track of the support plate are perpendicular to each other.

[0017] By adopting the above technical solution, since the moving track of the rack and the moving track of the support plate are perpendicular to each other, when the support plate is moved, the rack will not slip due to inertia, ensuring the stability of the rack and also ensuring the stability when the container is clamped.

[0018] Optionally, the elastic member is a spring, and the two ends of the spring are respectively fixed to the support plate and the rack. When the spring is in the natural state, the adjacent clamping parts are in the gathered state.

[0019] By adopting the above technical solution, the spring can push the rack to move, so that the rack drives the gear ring to rotate, the gear ring drives the turntable to rotate, and the turntable drives the clamping parts to gather in the direction of approaching each other, thereby realizing the clamping of the container.

[0020] Optionally, a guide rod is fixedly arranged on the support plate, the guide rod is slidably connected with the rack, and the spring is sleeved on the guide rod.

[0021] By adopting the above technical solution, the guide rod plays a guiding role in the movement of the rack. At the same time, the guide rod also plays a limiting role on the spring, so that the spring will not be skewed when it expands and contracts.

[0022] Optionally, a connecting frame is fixedly arranged on the rack, a blocking part is hinged on the connecting frame, and a clamping block is fixedly arranged on the support plate. When the blocking part is stuck on the clamping block, the adjacent clamping parts are in the open state.

[0023] By adopting the above technical solution, the rack can be driven to move by moving the connecting frame. When the connecting frame is moved to a position where the blocking portion can be stuck on the clamping block, the clamping portion is in an open state, which facilitates placing the container in the middle of the clamping portion.

[0024] Optionally, an elastic piece for pushing the blocking portion against the support plate is fixedly arranged on the connecting frame, and the side of the clamping block facing the blocking portion is an inclined surface.

[0025] By adopting the above technical solution, by pushing the connecting frame in the direction close to the clamping block, the blocking portion can be made to abut against the inclined surface and cross over the clamping block from the inclined surface, so that the clamping block is stuck on the blocking portion, restricting the movement of the blocking portion.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Pull the support plate out of the far-infrared drying oven, then open the clamping portion, and place the container containing the soil sample between the clamping portions. Drive the turntable to rotate through the driving assembly, so that the turntable drives the clamping portion to slide along the arc-shaped groove, thereby pushing the clamping portion in the direction of approaching each other, so that the clamping portion clamps on the container, realizing the clamping and positioning of the container and ensuring the stability of the container on the support plate.

[0028] 2. By moving the connecting frame, the rack can be driven to move. When the connecting frame is moved to a position where the blocking portion can be stuck on the clamping block, the clamping portion is in an open state, which facilitates placing the container in the middle of the clamping portion.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The technical solutions in the present application will be further described in detail below with reference to the accompanying drawings.

[0035] An infrared drying oven for measuring soil moisture content is disclosed in an embodiment of the present application. Please refer to Figure 1 and Figure 2 , an infrared drying oven for measuring soil moisture content includes a far-infrared drying oven 1, a support plate 2, a plurality of clamping parts 3, a turntable 4 and a driving assembly.

[0036] Among them, please refer to Figure 1 , the support plate 2 is slidably arranged in the far-infrared drying oven 1 and is used to support the container for holding the soil sample. A plurality of clamping parts 3 are all slidably arranged on the support plate 2, and four clamping parts 3 are in a group. A clamping space for placing the soil sample container is formed among the four clamping parts 3 in a group. The container is fixed on the support plate 2 through the clamping action of the clamping parts 3, thus effectively preventing the container from slipping or tilting when the support plate 2 is drawn out.

[0037] Please refer to Figure 2 and Figure 3 , the turntable 4 is rotatably arranged on the support plate 2. A group of clamping parts 3 corresponds to one turntable 4. Four arc-shaped grooves 41 are formed in the turntable 4. The bottom of the clamping part 3 is slidably connected with the arc-shaped groove 41. The arc-shaped groove 41 extends from the outer circle of the turntable 4 towards the center of the circle. When the turntable 4 rotates, the clamping part 3 can be driven to move along the arc-shaped groove 41, so as to realize the gathering or opening of the clamping parts 3.

[0038] Please refer to Figure 2 and Figure 3 , the driving assembly is used to drive the turntable 4 to rotate, and includes a gear ring 51 fixedly arranged on the turntable 4, a rack 52 slidably arranged on the support plate 2 and an elastic member for pushing the rack 52 to move. The gear ring 51 and the rack 52 are meshed. The rotation of the gear ring 51 can be driven by the movement of the rack 52, and then the turntable 4 is driven to rotate. Among them, the elastic member is a spring 53. One end of the spring 53 is fixedly connected with the support plate 2, and the other end of the spring 53 is fixedly connected with the rack 52. Under the action of the spring 53, the rack 52 can move on the support plate 2, so as to change the distance between adjacent clamping parts 3, and the clamping parts 3 are gathered together to clamp the container. When the spring 53 is in the natural state, the clamping parts 3 are in the gathered state, so that when the rack 52 is not affected by external force, the clamping parts 3 can always maintain the clamping state of the container, thus effectively preventing the container from slipping or tilting during the test.

[0039] Please refer to Figure 2 , in order to further improve the stability of the container, the movement track of the rack 52 and the movement track of the support plate 2 are set to be perpendicular to each other, so that when the support plate 2 moves in the far-infrared drying oven 1, the rack 52 will not slip due to inertia, thus ensuring the stability of the container during clamping.

[0040] Please refer to Figure 3, a guide rod 21 is fixedly arranged on the support plate 2. The guide rods 21 correspond to the racks 52 one by one, and the guide rods 21 are slidably connected to the racks 52. The guide rods 21 play a guiding role in the movement of the racks 52, ensuring that the racks 52 can move stably along a predetermined trajectory. At the same time, a spring 53 is sleeved on the guide rod 21, and the guide rod 21 plays a guiding and limiting role for the spring 53, so that the spring 53 will not be skewed during expansion and contraction, ensuring the normal use of the spring 53.

[0041] Please refer to Figure 3 and Figure 4 , in order to facilitate the staff to control the opening of the clamping part 3, a connecting frame 61 is fixedly arranged on the rack 52, and the connecting frame 61 can drive all the racks 52 to move synchronously. A blocking part 62 is hinged on the connecting frame 61, and a clamping block 63 is fixedly arranged on the support plate 2. When the connecting frame 61 is pushed towards the clamping block 63, the clamping part 3 can be opened. At this time, the blocking part 62 is rotated so that the blocking part 62 is stuck on the clamping block 63, and the position of the connecting frame 61 can be fixed, so that the clamping part 3 is kept in an open state, facilitating the staff to place the container.

[0042] Please refer to Figure 4 , in order to further improve the operation convenience, an elastic sheet 64 for pushing the blocking part 62 against the support plate 2 is also arranged on the connecting frame 61. One end of the elastic sheet 64 is fixedly arranged on the connecting frame 61, and the other end of the elastic sheet 64 abuts against the blocking part 62. At the same time, the side of the clamping block 63 facing the blocking part 62 is arranged as an inclined surface structure. The elastic sheet 64 can apply a certain elastic force to the blocking part 62, so that it always has a tendency to rotate towards the clamping block 63. When the connecting frame 61 is pushed towards the clamping block 63, the blocking part 62 will abut against the inclined surface and cross over the clamping block 63 from the inclined surface, so that the blocking part 62 can be stuck on the clamping block 63.

[0043] The implementation principle of the embodiment of the present application is as follows: First, overcome the elastic force of the spring 53, push the connecting frame 61 towards the clamping block 63, so that the blocking part 62 can be stuck on the clamping block 63, thereby driving the clamping part 3 to open. Place the container containing the soil sample in the opened clamping part 3. Release the blocking part 62, and under the elastic force of the spring 53, the rack 52 drives the turntable 4 to rotate, driving the clamping part 3 to gather and clamp the soil sample container. Finally, push the support plate 2 into the far-infrared drying oven 1 for heat treatment.

[0044] The embodiments of the present specific implementation manners are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
