Description

Technical Field

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

[0002] Soil sieving is a key step in soil testing and analysis. It is mainly used to separate soil particles of different sizes, providing basic data for subsequent experiments such as physicochemical properties and pollutant analysis. It is widely used in various laboratories for sample grading, sieving, analysis, and testing.

[0003] Soil sieving devices are often used to separate soil particles of different sizes for subsequent experimental analysis. However, existing soil sieving devices typically use multiple stacked sieving discs to sieve the soil sequentially from top to bottom. For example, a soil sieving device mentioned in publication number "CN218190970U" uses an adjusting element to fix multiple sieving discs simultaneously. This means that after soil sieving is completed, if it is necessary to test the soil in one of the lower sieving discs, the adjusting element must be removed, and then all the sieving discs above that disc must be moved before it can be taken out, which is inconvenient for operation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a soil screening device for soil testing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil sieving device for soil testing, comprising a sieving instrument, wherein two sets of fixed shafts are fixed inside the sieving instrument, an adjusting component is sleeved on the outer surface of the fixed shaft, and a rotating component is threadedly connected to the outer surface of the fixed shaft, and further comprising:

[0006] Several sets of adjustable screening components are placed on the screening instrument for individually removing the screened soil.

[0007] The adjustable screening component includes a first arc plate and a second arc plate. A limit ring is fixed to the bottom of the first arc plate, and an annular baffle is fixed to the inner wall of the second arc plate. A screening screen is fixed to the bottom of the annular baffle.

[0008] As described above, a first fixing member is fixed on both sides of the first arc-shaped plate, and a second fixing member is fixed on both sides of the second arc-shaped plate. A round shaft is fixed inside the second fixing member, and a reset spring and a limiting member are sleeved on the outer surface of the round shaft.

[0009] As described above, the bottom of the limiting ring is connected to an adjacent set of first arc-shaped plates, the rotating component is in pressing contact with the adjusting component, and the adjusting component is in pressing contact with the first arc-shaped plate located at the top.

[0010] As described above, when the first arc-shaped plate and the second arc-shaped plate are joined together, they form a ring, and the first arc-shaped plate covers the outer surface of the annular baffle.

[0011] As described above, the reset spring is elastically supported between the second fixing member and the limiting member, and the diameter of the mesh holes in the several sets of screening screens decreases sequentially from top to bottom.

[0012] As described above, the end of the limiting member is chamfered, and the end of the limiting member passes through the first fixing member and is movably engaged with the first fixing member.

[0013] Compared with existing technologies, this soil screening device for soil testing has the following advantages:

[0014] I. This utility model, through the cooperation between the first arc plate and the second arc plate, after the adjustable screening component is clamped by the adjusting member, through the cooperation between the second arc plate and the first arc plate, can drive one set of second arc plates to separate from the inner wall of the corresponding first arc plate, thereby driving the annular baffle and screening screen to separate from the first arc plate and the limiting ring, so that the soil to be tested can be taken out without removing the adjusting member.

[0015] Second, this utility model uses a chamfer at the end of the limiting member. When the chamfer of the limiting member is pressed against the first fixing member, it will drive the limiting member to move along the outer surface of the circular shaft. After the end of the limiting member passes through the first fixing member, the elastic force of the return spring will drive the limiting member to engage with the first fixing member, thereby positioning the first arc plate and the second arc plate and preventing the first arc plate from separating from the second arc plate when the adjustable screening assembly vibrates.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

Detailed Implementation

[0023] 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.

[0024] like Figure 1-5 As shown, this utility model provides a soil sieving device for soil testing, including a sieving instrument 1. Two sets of fixed shafts 2 are fixed inside the sieving instrument 1. Adjusting components 4 are sleeved on the outer surface of the fixed shafts 2, and rotating components 5 are threadedly connected to the outer surface of the fixed shafts 2. The device also includes:

[0025] Several sets of adjustable screening components 3 are placed on the screening instrument 1 for individually removing the screened soil.

[0026] The adjustable screening component 3 includes a first arc plate 31 and a second arc plate 32. A limit ring 33 is fixed to the bottom of the first arc plate 31, and an annular baffle 34 is fixed to the inner wall of the second arc plate 32. A screening screen 35 is fixed to the bottom of the annular baffle 34.

[0027] Through the cooperation between the first arc plate 31 and the second arc plate 32, after the adjustable screening component 3 is clamped by the adjusting member 4, the cooperation between the second arc plate 32 and the first arc plate 31 can drive one set of the second arc plate 32 to separate from the inner wall of the corresponding first arc plate 31, thereby driving the annular baffle 34 and the screening screen 35 to separate from the first arc plate 31 and the limiting ring 33, so that the soil to be tested can be taken out without removing the adjusting member 4.

[0028] like Figure 3As shown, the first arc plate 31 is fixed with a first fixing member 6 on both sides, and the second arc plate 32 is fixed with a second fixing member 7 on both sides. A round shaft 8 is fixed inside the second fixing member 7, and a reset spring 9 and a limiting member 10 are sleeved on the outer surface of the round shaft 8.

[0029] The cooperation between the limiting member 10 and the round shaft 8 allows the limiting member 10 to slide along the outer surface of the round shaft 8, thereby separating the limiting member 10 from the first fixing member 6. At this time, the positioning of the first arc plate 31 and the second arc plate 32 can be released, making it easier to disassemble them.

[0030] like Figure 1 , 4 As shown, the bottom of the limiting ring 33 is connected to an adjacent set of first arc plates 31, the rotating part 5 is in contact with the adjusting part 4, and the adjusting part 4 is in contact with the first arc plate 31 located at the top.

[0031] Through the cooperation between the rotating part 5 and the adjusting part 4, the adjusting part 4 can be rotated to squeeze the rotating part 5, thereby squeezing the adjustable screening assembly 3 through the rotating part 5. This prevents the two adjacent adjustable screening assemblies 3 from separating when the screening instrument 1 drives the adjustable screening assembly 3 to vibrate.

[0032] like Figure 2 , 5 As shown, when the first arc plate 31 and the second arc plate 32 are joined together, they form a ring, and the first arc plate 31 covers the outer surface of the annular baffle 34.

[0033] Through the cooperation between the first arc plate 31 and the annular baffle 34, and the cooperation between the first arc plate 31 and the second arc plate 32, the second arc plate 32 can drive the annular baffle 34 to separate from the first arc plate 31. Therefore, the annular baffle 34 can drive the screening screen 35 to remove soil particles.

[0034] like Figure 3 As shown, the reset spring 9 is elastically supported between the second fixing member 7 and the limiting member 10, and the diameter of the mesh holes of several sets of screening screens 35 decreases sequentially from top to bottom.

[0035] The design of the return spring 9 enables the limiting member 10 to have good elastic return performance. Since the return spring 9 is in a compressed state, it will apply an elastic force to the limiting member 10, thereby making the fit between the limiting member 10 and the first fixing member 6 tighter.

[0036] like Figure 3 As shown, the end of the limiting member 10 is chamfered, and the end of the limiting member 10 passes through the first fixing member 6 and is movably engaged with the first fixing member 6.

[0037] The chamfer at the end of the limiting member 10 causes the limiting member 10 to move along the outer surface of the round shaft 8 when it is pressed against the first fixing member 6. After the end of the limiting member 10 passes through the first fixing member 6, the elastic force of the return spring 9 will cause the limiting member 10 to engage with the first fixing member 6, thereby positioning the first arc plate 31 and the second arc plate 32 and preventing the first arc plate 31 from separating from the second arc plate 32 when the adjustable screening assembly 3 vibrates.

[0038] Working principle:

[0039] After the sieve 1 is started and the adjustable sieve assembly 3 is controlled to sieve the soil, the user can press the limiting member 10 and slide it along the outer surface of the circular shaft 8, thereby causing the limiting member 10 to separate from the first fixing member 6. At this time, the first arc plate 31 and the second arc plate 32 can be released from their positions. At the same time, through the cooperation between the first arc plate 31 and the second arc plate 32, one set of second arc plates 32 can be driven to separate from the inner wall of the corresponding first arc plate 31. Therefore, the annular baffle 34 and the sieve screen 35 can be disengaged from the first arc plate 31, so that the adjusting member 4 does not need to be removed, and the adjustable sieve assembly 3 located above it can be taken out, and the soil to be tested can be taken out.

[0040] 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.
