Description

Technical Field

[0001] This utility model relates to the field of soil drying technology, specifically a soil drying device for testing. Background Technology

[0002] As a crucial transportation infrastructure, the quality of the railway subgrade directly impacts the safety and comfort of railway operations. Subgrade hardness is a key indicator for assessing subgrade quality. During railway construction, it is typically necessary to test the soil hardness of newly laid subgrade to ensure it meets design standards. Soil hardness is closely related to its moisture content. To accurately determine soil hardness, the moisture in the soil sample must be removed through drying. After drying, parameters such as dry density can be measured more precisely.

[0003] Although existing soil drying and testing devices have basic drying functions, operators often place the soil sample boxes haphazardly when putting them in. In many cases, the edges of the soil sample boxes are close to the heating tubes, while the central sample is far away from the heating tubes. In addition, slight vibrations inside the drying chamber during the drying process can also easily cause the soil sample boxes to shift, resulting in poor heating uniformity of the soil samples. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a soil drying device for testing, so as to solve the problem mentioned in the background art that the soil sample box is easily deviated from the set position.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a soil drying device for testing, comprising a box frame structure, wherein the box frame structure is provided with three independently controlled drying components arranged vertically, and the box frame structure is also provided with three magnetic guide components, which are respectively located above the three drying components. A material box is placed on the magnetic guide components, and a magnetic suction plate is embedded in the bottom of the material box. Ventilation holes are provided on the wall of the material box. The magnet guiding assembly includes a supporting base plate fixed to the inner wall of the box frame structure. The top surface of the supporting base plate has several through slots. A magnet adsorption plate is installed on the outer side of the edge of the through slot on the top surface of the supporting base plate. Guide structures are installed on both sides of the magnet adsorption plate.

[0006] Preferably, the magnetic adsorption plate includes a rectangular frame strip portion that is attached to the top surface of the supporting base plate, and a rear baffle is installed on the back of the rectangular frame strip portion.

[0007] Preferably, the inner width and inner length of the rectangular frame portion are adapted to the through groove, and the width of the material box is greater than the inner width of the through groove and at least equal to the outer width of the rectangular frame portion.

[0008] Preferably, the guide structure and the supporting base plate are detachably connected by bolts, and the distance between the front end and the middle end of the two guide structures gradually decreases, while the distance between the middle end and the rear end is adapted to the width of the material box.

[0009] Preferably, the drying assembly includes a heat insulation plate installed along the inner wall of the box frame structure, a wiring frame installed on the top surface of the heat insulation plate, and a plurality of heat-conducting rods installed on the inner wall of the wiring frame.

[0010] Preferably, the front wall of the box frame structure is fitted with three rows of vertically arranged baffles via hinges. The three rows of baffles are at the same height as the three magnetic guide components, and the number of baffles in each group is the same as the number of magnetic adsorption plates in the magnetic guide components.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes the magnetic attraction between the magnetic plate at the bottom of the material box and the magnetic adsorption plate arranged along the periphery of the groove on the top surface of the support base plate, combined with the guide structure on both sides of the magnetic adsorption plate, to achieve rapid blind pushing, positioning, and fixing of the material box. This ensures that the material box is always located directly above the corresponding groove, allowing hot air to directly pass through the groove and contact the bottom of the material box, thus ensuring the drying effect.

[0012] 2. Several baffles are independently set on the box frame structure of this utility model, which facilitates the use of a robotic arm to individually pick up and place a single group of soil samples. This can prevent a large amount of heat loss inside the box frame structure 1 and ensure that the samples that have not been dried are still in a stable temperature environment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model proposes a soil drying device for testing, which can effectively dry the soil. The soil drying and testing device specifically includes a frame structure 1 for supporting the overall components, a drying component 2 for heating and drying the soil, a material box 4 for holding the soil, and a magnetic guide component 3 for positioning the material box 4. The material box 4 is mounted on the magnetic guide component 3, and a magnetic suction piece 401 is embedded in the bottom of the material box 4. The magnetic suction piece 401 can be attracted to a predetermined position on the magnetic guide component 3. Ventilation holes 402 are provided on the wall of the material box 4 to facilitate the discharge of water vapor generated during the soil drying process.

[0017] The drying components 2 consist of three sets, arranged vertically within the frame structure 1. Each set is independently controlled, allowing for temperature and structural adjustments within the space separated by the three drying components 2, based on actual conditions. Each drying component 2 includes a heat insulation plate 201 installed along the inner wall of the frame structure 1. A wiring frame 202 is installed on the top surface of the heat insulation plate 201, and several heat-conducting rods 203 are installed on the inner wall of the wiring frame 202. These heat-conducting rods 203 are connected to an external temperature controller via wires. When powered on, they generate heat, which is then used to heat and dry the soil in the upper material box 4 through thermal radiation and conduction.

[0018] In addition, there are three sets of magnet guide components 3, which are located directly above the three sets of drying components 2. Each set of magnet guide components 3 includes a support base plate 301 that is welded to the inner wall of the box frame structure 1 or can be detachably fixed by bolts. Several through slots 302 are evenly opened along the top surface of the support base plate 301. A magnet adsorption plate 303 is installed on the top surface of the support base plate 301 along the outer edge of the through slot 302. The magnetic adsorption plate 303 includes a rectangular frame strip 3031 that adheres to the supporting base plate 301 and a rear baffle 3032 welded to the back of the rectangular frame strip 3031. The inner width and inner length of the rectangular frame strip 3031 are adapted to the through groove 302. The width of the material box 4 is greater than the inner width of the through groove 302 and at least equal to the outer width of the rectangular frame strip 3031. This prevents the material box 4 from falling down from the through groove 302, ensures that the material box 4 can be accurately positioned to fit the rectangular frame strip 3031, and allows the heat generated by the corresponding drying component 2 below to directly contact the bottom of the material box 4. Compared to the traditional method of heat conduction through the supporting base plate 301 to the bottom of the material box 4, which has thermal resistance, the through groove 302 allows the bottom of the material box 4 to be directly exposed to the hot air flow above the heat-conducting rod 203, reducing intermediate heat conduction links and allowing heat to be more concentrated on the soil, thereby accelerating the soil heating and drying speed.

[0019] Specifically, in practical applications, the soil sample to be dried is evenly spread inside the material box 4. Then, a robotic arm can be used to hold the material box 4 and place it on the magnetic adsorption plate 303 of the magnetic guide assembly 3. The magnetic suction plate 401 at the bottom of the material box 4 engages with the magnetic adsorption plate 303, achieving rapid positioning and fixation of the material box 4. Afterward, the temperature and drying time of each drying assembly 2 are set by an external temperature controller, causing the heat-conducting rod 203 to be energized and heated. The heat is transferred to the bottom of the material box 4 through the through-slot 302, heating the soil. Water vapor generated in the bottom and middle layers of the material box 4 during the drying process can be discharged through the vent holes 402 in the wall, preventing condensation inside the material box 4 and affecting drying efficiency. After drying, the power to the heat-conducting rod 203 is cut off, and the external robotic arm is again used to extend into the frame structure 1 to clamp and remove the material box 4 from its designated position.

[0020] Following the above, in order to effectively avoid the problem of misalignment when the material box 4 is placed on the magnetic adsorption plate 303, such as... Figure 1 , Figure 3 and Figure 4As shown, guide structures 304 are installed on both sides of the magnetic adsorption plate 303. The guide structures 304 are detachably connected to the support base plate 301 by bolts. The distance between the front and middle of the two guide structures 304 gradually decreases, and the distance between the middle and rear ends is adapted to the width of the material box 4. When the material box 4 is placed, the rear end of the material box 4 first enters the wide-spacing area of ​​the front end of the guide structure 304. Then, as the material box 4 continues to be pushed backward, the distance between the guide structures 304 decreases. The side walls of the guide structures 304 guide the material box 4 to gradually align its position and finally accurately fit the magnetic adsorption plate 303, achieving blind push positioning without visual alignment.

[0021] Furthermore, since the rear end of the guide structure 304 is the same width as the material box 4, it can limit the left and right offset of the material box 4, ensuring that the magnetic suction piece 401 at the bottom of the material box 4 is completely aligned with the magnetic adsorption plate 303, and preventing the material box 4 from tilting due to magnetic offset.

[0022] Meanwhile, the guide structure 304 cooperates with the rear baffle 3032 to form three-dimensional positioning on the left, right, and rear sides, further effectively preventing displacement of the material box 4. The inner wall of the guide structure 304 is smooth to reduce frictional resistance when the material box 4 is inserted.

[0023] like Figure 1 As shown, the front wall of the box frame structure 1 is hinged to have three rows of vertically arranged baffles 101. The three rows of baffles 101 are at the same height as the three magnetic guide assemblies 3, and the number of baffles 101 in each group corresponds to the number of magnetic adsorption plates 303 within the magnetic guide assembly 3. When the baffles 101 are closed, they form a seal, preventing operators from accidentally touching high-temperature components inside the box frame structure 1, thus reducing the risk of burns. Furthermore, when a single soil sample needs to be removed, only the corresponding row of baffles 101 needs to be opened with the help of the robotic arm; the other baffles 101 remain closed, preventing significant heat loss from the box frame structure 1 and ensuring that samples that are not yet fully dried remain in a stable temperature environment.

[0024] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
