Abstract
Description
Technical Field
[0001] The utility model relates to an auxiliary tool for soil detection, in particular to an air drying device for soil detection. Background Art
[0002] When inspecting the content of other components in the soil (excluding water content testing), it is often necessary to dry the soil sample. Existing air-drying equipment for soil testing often involves placing the soil inside an air-drying chamber and air-drying it under the stirring of a stirring device. This causes the soil to accumulate inside the chamber. Although the stirring device allows the soil inside to be flipped to the outside, the efficiency of flipping the accumulated soil sample is relatively limited, and the soil that is flipped to the outside is exposed to the circulating hot air for a short period of time. Furthermore, existing air-drying equipment dries the soil inside the chamber all at once, rather than drying parts gradually. Larger components in the soil, such as stones, metals, glass, and plastic, also remain mixed with the soil, affecting drying efficiency. Utility Model Content
[0003] The technical problem to be solved by the present invention is that a large amount of soil is accumulated inside the existing air-drying equipment for soil testing, the air-drying efficiency is relatively low, and the soil cannot be air-dried gradually. During the air-drying process, stones, metals, and glass that do not need to be air-dried cannot be discharged in advance. In view of the above-mentioned defects of the prior art, a soil drying device for soil testing is provided.
[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0005] A soil drying device for testing is constructed, comprising a base, a bracket, a vibration device and a drying box, wherein the bracket is fixedly arranged on the upper side of the base, the drying box is arranged at the upper end of the bracket, the vibration device is arranged on the drying box, a hot air inlet pipe is provided near the lower end of the side wall of the drying box, and an air outlet is provided near the upper end, a drying slide is provided in the drying box, the drying slide comprises a first drying slide and a second drying slide, and the first drying slide and the second drying slide are both spiral, and the first drying slide and the first drying slide are spiral. The two air-drying slides are arranged alternately from top to bottom. The surface of the first air-drying slide for the soil to be tested to spirally slide downward for air drying is non-porous. The second air-drying slide is provided with a screening channel, which runs through the upper and lower surfaces of the second air-drying slide. When in use, the vibration device vibrates to make the soil to be tested slide downward while being air-dried on the first air-drying slide and the second air-drying slide. The second air-drying slide screens the soil to be tested that enters it, so that part of the soil to be tested first enters the first air-drying slide below for further air-drying treatment.
[0006] It should be noted that the vibration of the vibration device makes the air-drying slide in a vibrating state, so that the soil to be tested can spirally slide down along the air-drying slide. Similarly, the soil to be tested that is gradually air-dried can also be crushed under the vibration of the air-drying slide, reducing the presence of large pieces of soil and gradually being air-dried during the sliding process.
[0007] Preferably, the inner lower end portion of the air-drying box is divided into an air-dried soil collecting chamber, which is located directly below the air-drying slide to collect part of the soil to be tested after being air-dried, screened and air-dried by the air-drying slide.
[0008] Preferably, the upper end of the air-drying chute starts with the first air-drying chute and the lower end ends with the second air-drying chute, and the end of the second air-drying chute is connected to the first discharge port on the side wall of the air-drying box; when in use, the second air-drying chute at the lower end will air-dry and screen the soil to be tested entering it, and the large pieces of soil to be tested remaining on the second air-drying chute will be discharged through the first discharge port, and the smaller soil to be tested will fall through the screening channel into the air-dried soil collection chamber.
[0009] Preferably, the adjacent first air-drying slides are fixedly connected at their connection points to allow the first air-drying slides and the second air-drying slides to form an integral spiral state.
[0010] Preferably, the number of spiral turns of the first air-drying slide is greater than the number of spiral turns of the second air-drying slide, so that part of the soil to be tested that is screened and dropped by the second air-drying slide can fall onto the first air-drying slide below it, and this part of the soil to be tested can still slide down along the first air-drying slide for air-drying treatment.
[0011] Preferably, the hot air inlet pipe extends into the air drying box, and one end of the hot air inlet pipe located inside the air drying box is bent downward so that the outlet end of the hot air inlet pipe located inside the air drying box is open downward to prevent the soil to be tested from entering the hot air inlet pipe, and the end of the hot air inlet pipe located outside the air drying box is connected to the external heat source through a pipe.
[0012] Preferably, a dust shield and a dust collecting plate are also provided on the outer wall of the air drying box, wherein the dust shield is arranged above the exhaust port, and the dust collecting plate is arranged below the exhaust port; the dust shield is used to block and change the movement direction of dust in the exhaust air, and the dust collecting plate is used to receive the dust whose movement direction is changed by the dust shield.
[0013] Preferably, the dust shield and the dust receiving plate are both skirt-shaped, the dust shield is in an oblique downward position, and the dust receiving plate is in an oblique upward position; the outer edge diameter of the dust shield is smaller than the outer edge diameter of the dust receiving plate.
[0014] Preferably, during the exhaust process, dust in the wind blown out of the exhaust port hits the lower surface of the dust shield, changes its direction of movement, and falls into the upper surface of the dust receiving plate.
[0015] Preferably, the top of the air-drying box is provided with an inlet for soil to be tested and the bottom is provided with a second discharge port. The top of the air-drying box is hingedly provided with a first cover for sealing the inlet for soil to be tested, and the second discharge port is threadedly provided with a second cover.
[0016] Preferably, an annular filter screen can be provided on the gap between the dust shield plate and the dust receiving plate for air flow to further remove soil dust in the air flow.
[0017] The beneficial effects of the present invention are:
[0018] First of all, the utility model arranges a spiral air-drying slide in the air-drying box, and the air-drying slide has a first air-drying slide and a second air-drying slide, wherein the first air-drying slide does not have a screening function, and the second air-drying slide has a screening function, so that the soil to be tested that has just entered the air-drying slide from the soil entrance at the top of the air-drying box is preliminarily air-dried in the first air-drying slide, so that the amount of soil to be tested entering the second air-drying slide is reduced, which is convenient for screening treatment. The screening of the second air-drying slide allows part of the soil to be separated from most of the soil samples to be tested in the first air-drying slide and enter the first slide below, so that the soil to be tested on the first slide below and the soil to be tested in the second slide above are in a uniform and thin state, which is more conducive to air-drying treatment; and the soil is in the air during the screening and falling process, and can be completely in contact with the drying airflow, which greatly improves the air-drying efficiency.
[0019] Secondly, the top air outlet of the utility model is provided with a dust shield and a dust collecting plate, which can remove most of the soil dust contained in the air flow discharged from the air drying box, and the removed soil dust can be collected by the dust collecting plate, and an annular filter is also provided between the dust collecting plate and the dust shield, which can ensure that the air flow finally discharged to the outside does not contain soil dust or the content is small.
[0020] Finally, the device can gradually air-dry the soil in sequence during the air-drying process. The gradually air-dried soil to be tested can be crushed to a certain extent under the vibration of the air-drying slide, thereby reducing the presence of large pieces of soil and improving air-drying efficiency.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0028] Example 1
[0029] like Figure 1-3 As shown, a soil drying device for testing includes a base 1, a bracket 2, a vibration device, and an air drying box 3. The bracket 1 is fixedly mounted on the upper side of the base 2 by welding, and a spring support plate 201 is provided near the upper end of the bracket 2. A mounting plate 301 is provided on the outer wall of the air drying box 3. The mounting plate 301 has mounting holes corresponding to the bracket 2 on the base 1. The air drying box 3 is fixedly mounted on the upper end of the bracket 2, and a spring 10 is mounted on the bracket between the mounting plate 301 and the spring support plate 201. The spring 10 provides an elastic connection between the air drying box 3 and the bracket 2. The vibration device is provided on the air drying box 3. When the vibration device is working, the air drying box 3 can be in a vibrating state due to the presence of the spring 10.
[0030] In this embodiment, a hot air inlet pipe 302 is provided near the lower end of the side wall of the air drying box 3, and the hot air inlet pipe 302 is used to inject hot air into the interior of the air drying box 3. An exhaust port 303 is provided near the upper end of the side wall of the air drying box 3, and the exhaust port 303 is used to discharge the airflow after the air drying process.
[0031] In this embodiment, an air-drying slide 4 is provided in the air-drying box 3. The air-drying slide 4 is used to receive the soil to be tested, so that the soil to be tested slides on the air-drying slide 4, and the air-drying process is completed during the sliding process. Specifically, the air-drying slide 4 includes a plurality of first air-drying slides 401 and a plurality of second air-drying slides 402, wherein the first air-drying slides 401 and the second air-drying slides 402 are both spiral-shaped, and the first air-drying slides 401 and the second air-drying slides 402 are alternately arranged from top to bottom, and the adjacent first air-drying slides 401 and the second air-drying slides 402 are connected at the connection point, so that the first air-drying slides 401 and the second air-drying slides 402 form an integral spiral state, and the surface of the first air-drying slide 401 for receiving the soil to be tested adopts a smooth surface design without holes, so that the soil to be tested can only be dried in the first air-drying slide 401. The soil to be tested slides on the slide 401 and is air-dried; a screening channel 4021 is provided on the second air-drying slide 402, and the screening channel 4021 runs through the upper and lower surfaces of the second air-drying slide 402, and the soil to be tested thereon can be screened through the screening channel 4021; when in use, the vibration device vibrates so that the soil to be tested slides downward while being air-dried on the first air-drying slide 401 and the second air-drying slide 402, and the second air-drying slide 402 screens the soil to be tested entering it, so that a part of the soil to be tested on the second air-drying slide 402 first enters the first air-drying slide 401 below for further air-drying treatment.
[0032] It should be noted that the vibration device is a vibration motor (not shown in the figure), which is fixed to the top or bottom of the air-drying box by bolts. The vibration of the vibration device puts the air-drying slide into a vibrating state, so that the soil to be tested can spirally slide downward along the air-drying slide 4. Similarly, the soil to be tested that is gradually air-dried can also be crushed under the vibration of the air-drying slide, reducing the presence of large pieces of soil, and is gradually air-dried during the sliding process.
[0033] Furthermore, the lower inner end of the air-drying box 3 is divided into an air-dried soil collecting chamber 304, which is located directly below the air-drying slide 4 to collect part of the soil to be tested after being screened and air-dried by the air-drying slide 4.
[0034] In this embodiment, the upper end of the air-drying slide 4 starts with the first air-drying slide 401 and the lower end ends with the second air-drying slide 402, and the end of the second air-drying slide 402 is connected to the first discharge port 305 on the side wall of the air-drying box 3; when in use, the second air-drying slide 402 at the lower end will air-dry and screen the soil to be tested entering its interior, and the remaining large pieces of soil to be tested on the second air-drying slide 402 will be discharged through the first discharge port 305, and the smaller soil to be tested will fall into the air-dried soil collection chamber 305 through the screening channel 4021.
[0035] It should be noted that the number of spiral turns of the first air-drying chute 401 is greater than the number of spiral turns of the second air-drying chute 402. In this way, part of the soil to be tested that is screened and dropped by the second air-drying chute 402 can fall on the first air-drying chute 401 below it, and this part of the soil to be tested will still slide downward along the first air-drying chute 401 for air-drying treatment, and will not bypass the first air-drying chute 401 below from the upper second air-drying chute 402 and directly fall into the second air-drying chute 402 below. That is, this can ensure that the screened soil to be tested has a sufficient residence time in the air-drying chute.
[0036] In this embodiment, the hot air inlet pipe 302 extends into the air drying box 3, and the end of the hot air inlet pipe 302 located inside the air drying box 3 is bent downward so that the outlet end of the hot air inlet pipe 302 located inside the air drying box 3 is open downward to prevent the soil to be tested from entering the hot air inlet pipe 302. The end of the hot air inlet pipe 302 located outside the air drying box 3 is connected to the external heat source through a pipe.
[0037] It should be noted that the air-drying box 3 has a soil inlet 306 for testing at the top and a second discharge port 307 at the bottom. A first cover 308 is hingedly mounted on the top of the air-drying box 3 to cover the soil inlet 306 for testing, and a second cover 309 is threadedly mounted on the second discharge port 307. The soil inlet 306 for testing is located directly above the starting end of the air-drying slide.
[0038] Example 2
[0039] like Figure 4-5As shown, the difference between this embodiment and embodiment 1 is that this embodiment removes dust from the airflow discharged from the exhaust port after drying to prevent the airflow discharged from the exhaust port from containing a large amount of dust and polluting the environment. Specifically, a dust shield 5 and a dust receiving plate 6 are also provided on the outer wall of the air drying box 3, wherein the dust shield 5 is provided above the exhaust port 303, and the dust receiving plate 6 is provided below the exhaust port 303; the dust shield 5 is used to block and change the direction of movement of dust in the exhaust air, and the dust receiving plate 6 is used to receive dust whose movement direction is changed by the dust shield 5. During the exhaust process, the dust in the air blown out of the exhaust port 303 hits the lower surface of the dust shield 5, changes its movement direction, and falls into the upper surface of the dust receiving plate 6.
[0040] Specifically, the dust shield plate 5 and the dust receiving plate 6 are both skirt-shaped, the dust shield plate 5 is in a slanted downward state, and the dust receiving plate 6 is in a slanted upward state; the outer edge diameter of the dust shield plate 5 is smaller than the outer edge diameter of the dust receiving plate 6.
[0041] An annular filter screen 7 may be provided on the gap between the dust shield plate 5 and the dust receiving plate 6 for air flow to further remove soil dust in the air flow.
[0042] It should be noted that the air-drying box 3 has a soil inlet 306 for testing at the top and a second discharge port 307 at the bottom. A first cover 308 is hingedly mounted on the top of the air-drying box 3 to cover the soil inlet 306 for testing, and a second cover 309 is threadedly mounted on the second discharge port 307. The soil inlet 306 for testing is located directly above the starting end of the air-drying slide.
[0043] Finally, it should be noted that both Example 1 and Example 2 also have an air-dried soil collection box 310. The air-dried soil collection box is a cylindrical structure with an open top. The air-dried soil collection box can be detachably placed on the upper side of the base, and the opening of the air-dried soil collection box is located directly below the second discharge port. In this way, when air drying is completed, the second cover can be removed to discharge the air-dried soil in the air-dried soil collection chamber through the second discharge port and collect it in the air-dried soil collection box.
[0044] It should be understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
