Technical Field
[0001] This utility model relates to the field of geotechnical testing equipment technology, and in particular to an integrated device for soil sample drying and crushing. Background Technology
[0002] In the field of geotechnical testing, soil sample pretreatment is a crucial step in ensuring accurate and reliable test results. To meet the stringent requirements of different tests on soil sample condition, soil samples typically need to be dried and pulverized.
[0003] Traditional soil sample drying methods mainly fall into two categories: natural air drying and oven drying. Natural air drying relies on the natural environment and requires no additional equipment investment, but its efficiency is extremely low, greatly affected by weather and other natural factors, and it takes a long time, making it difficult to ensure the timely conduct of geotechnical tests. While oven drying can shorten the drying time to some extent, after drying, the soil sample needs to be transferred to other equipment for crushing. The entire process is cumbersome and requires a high degree of manual intervention, which not only increases labor intensity and reduces the overall efficiency of soil sample processing, but also easily leads to soil contamination from the external environment or soil loss during the transfer and crushing process, affecting soil sample quality and the accuracy of test data. Utility Model Content

The motor is fixed on the outer side wall of the box, and the rotating shaft drives the stirring and crushing blades to stir the soil sample.
[0009] As a further implementation, an air outlet is provided on the side wall of the enclosure, and an air outlet duct is connected through the air outlet.
[0010] As a further implementation, the stirring and pulverizing blades have a set curvature and tilt angle.
[0011] As a further implementation, the rear side wall of the box is provided with a first transverse opening, and the opposite side wall adjacent to the rear side wall of the box is provided with a first slide rail.

Detailed Implementation
[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0022] Example 1 In a typical embodiment of this utility model, refer to Figures 1-2 As shown, an integrated device for drying and crushing soil samples includes a housing 1, a hot air generator 4, a collection box 9, and a tray 8.
[0023] The outer shape of the box 1 is a cube with a rectangular cross-section and a hollow interior, forming a sealed cavity for mixing, crushing and drying.
[0024] The chamber contains a rotating shaft 6, which has mixing and pulverizing blades to mix the soil sample entering the chamber. Figure 1 As shown, in this embodiment, the rotating shaft is arranged laterally, parallel to the front and rear side walls of the housing 1. One end of the shaft is rotatably connected to the inside of the right side wall of the housing via a bearing 601 structure, and the other end passes through the left side wall of the housing 1 and is connected to the output end of the motor 7. A rotary sealing structure is provided between the rotating shaft and the left side wall of the housing 1, which is existing technology.
[0025] The motor 7 is installed on the outer side of the left side wall of the housing 1. The stirring and pulverizing blades on the rotating shaft are evenly arranged. The motor drives the stirring and pulverizing blades to stir the soil sample through the rotating shaft. The stirring and pulverizing blades 602 have a set curvature and inclination angle, which can both stir the soil sample and pulverize it during rotation.
[0026] like Figure 1 and Figure 2 As shown, the top of the box 1 is provided with a feeding port 2, and a sealing cover 3 is hinged to the rear side of the feeding port 2. A handle 301 is provided on the outside of the sealing cover 3.
[0027] The feed port 2 is a rectangular opening, and the corresponding sealing cover 3 is also a rectangular cover. A sealing strip is provided at the bottom edge of the cover, and a sealing groove is provided at the top edge of the opening. When the sealing cover is closed by the handle 301, the sealing strip and the sealing groove cooperate to seal the feed port.
[0028] In an optional example, a locking structure can be installed between the sealing cover 3 and the top cover of the housing to prevent the sealing cover 3 from being accidentally opened; the locking structure is prior art.
[0029] After the soil sample is fed into the sealed cavity through the feed port, the operator closes the sealing cover 3 to ensure good sealing of the cavity and prevent hot air leakage and external impurities from entering.
[0030] like Figure 1 As shown, in order to achieve both stirring and drying of the soil sample inside the box, a hot air generator 4 is installed on the top of the box 1 in this embodiment. Its output end is connected to the inside of the box through a hot air pipe 401. The hot air generated by the hot air generator 4 can enter the sealed cavity from the top cover of the box through the hot air pipe 401 to complete the drying of the soil sample inside the cavity.
[0031] Understandably, the hot air generator 4 is equipped with a temperature adjustment zone 402, which has a button for adjusting the hot air outlet temperature, allowing for precise adjustment of the hot air temperature according to the characteristics of different soil samples.
[0032] An air outlet 5 is provided on the side wall of the box 1. The side wall of the box is connected to the air outlet 5 through the air outlet 5, which can discharge the hot and humid air generated during the drying process.
[0033] like Figure 1 As shown, a stainless steel dust filter 502 is installed on the inner side wall of the box to prevent fine dust particles (especially clay / dust) generated when the mixing and crushing blades 602 rotate from clogging the air outlet 5 or ventilation duct 501.
[0034] like Figure 1 and Figure 2 As shown, the collection box 9 is located at the bottom of the box body and is pulled out to the side wall of the box body 1; the tray 9 is located between the collection box 9 and the mixing and crushing blades 602, and is also pulled out to the side wall of the box body 1. The tray is set at an angle relative to the plane where the collection box is located.
[0035] Specifically, such as Figure 2 As shown, the rear side wall of the box 1 is provided with a first transverse opening. The length of the first transverse opening is adapted to the length of the rear side wall of the box, and the width is adapted to the thickness of the rear end of the tray 8. The first transverse opening is used for the tray 8 to be inserted into the box 1 from this point.
[0036] Furthermore, the inner side of the opposite side wall (i.e. the left and right side walls of the box) adjacent to the rear side wall of the box is provided with a first slide rail. Since the tray 8 needs to be set at an angle, the two first slide rails are set at an angle.
[0037] In this embodiment, the stirring and pulverizing blades 602 on the rotating shaft 6 are made of high-strength wear-resistant alloy material. Their shape is designed with a certain curvature and inclination angle, and they are evenly distributed along the axial direction. Driven by a motor, the stirring and pulverizing blades 602 rotate at high speed, also performing a stirring function. This breaks up accumulated soil clumps, and the curvature and inclination angle create a shearing, impacting, and turning effect on the soil sample. Even if the tray is tilted, the rotation range of the blades can cover the soil sample area on the tray. Through continuous stirring, the soil sample is constantly lifted and broken up, ensuring uniform pulverization.
[0038] The tray 8 has a rectangular plate structure. The left and right sides of the tray 8 are used to insert into the first slide rail to achieve sliding engagement with the first slide rail. A lifting handle 801 is provided on the rear side of the tray 8. The tray 8 can be inserted into the box body through the first transverse opening. The front end of the tray abuts against the front side wall of the box body, which is to isolate the cavity inside the box body 1, so that the soil sample entering the box body is agitated and crushed by the stirring and crushing blades on the upper part of the tray 8.
[0039] After the crushing work is completed, the crushed soil sample needs to be discharged. At this time, the tray can be pulled out of the box by lifting handle 801. Since the tray 8 is tilted, when the tray 8 is pulled out, the soil sample slides from the tilted surface of the tray 8 into the collection box 9 below.
[0040] like Figure 1 and Figure 2 As shown, a second slide rail is provided on the inner side of the left and right side walls of the box. The second slide rail is parallel to the horizontal plane. A second horizontal opening is provided on the front side wall of the box. The collection box has a drawer-type structure with an opening at the top. Sliding blocks that cooperate with the second slide rail are provided on the outer side of the left and right side walls to achieve sliding cooperation between the two sides and the second slide rail. The second slide rail is lower than the first slide rail, and a handle is provided on the collection box.
[0041] like Figure 1 As shown, the collection box 9 can be pushed into the box body by the handle 901. After the soil sample is crushed and dried, the collection box 9 can be pulled out by the handle 901 for easy removal of the dried and crushed soil sample. It can be understood that in this embodiment, both the first slide rail and the second slide rail are represented by slide rail 10.
[0042] In an optional example, pallet 8 is made of a high-temperature resistant and corrosion-resistant metal material. It is understood that corresponding sealing strip structures are required between the pallet and the aggregate bin and the side wall of the box, and the sealing strip structure is an existing technology.
[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
