Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of soil sieves, and in particular to a soil sample sieve for geotechnical testing. Background Technology
[0002] Soil samplers are important instruments for soil sampling and analysis. They are designed to determine the particle composition and size distribution of soil, thereby analyzing its engineering properties and classification. They can perform multi-stage sieving as needed and weigh soil particles of different sizes. They have wide applications in soil science, geology, agriculture, and environmental science, providing scientific basis for soil classification, improvement, geological exploration, and environmental monitoring.
[0003] The existing Chinese utility model patent with application number CN22121343486.0 relates to a volatile organic compound contaminated soil sieve, which includes a pressure plate, sieve box, box cover, connecting device, sliding plate and clamping arm, etc., which can make multiple sieve boxes more stable when stacked together, so that the sieve boxes will not fall apart when vibrated.
[0004] However, in actual use, the above-mentioned device does not have the ability to weigh the soil in a single sieve box. Operators need to pour out the soil sample from the sieve box before weighing it, and the soil adhering to the sieve box will cause the data error to increase. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a soil sample sieve for geotechnical testing, which uses a sieving device to perform multi-stage sieving of soil samples, uses a dustproof device to protect the sieving device from dust, reduces the pollution of the operating environment caused by dust overflow during the sieving process, and uses a weighing device to quickly weigh the various soil masses in the sieving device. Soil data can be obtained without the operator having to pour out the soil, thus improving the practicality of the device.
[0006] This utility model discloses a soil sample sieve for geotechnical testing; it includes a sieve device, a dustproof device, and an auxiliary device. The dustproof device is installed on the sieve device, a weighing device is connected to the sieve device, and the auxiliary device is installed on the sieve device. The sieve device performs multi-stage sieve analysis on soil samples, the dustproof device provides dust protection to the sieve device to reduce the pollution of the operating environment caused by dust overflow during the sieve process, and the weighing device quickly weighs the various soil masses in the sieve device, obtaining soil data without the need for operators to empty the soil, thus improving the practicality of the device.
[0007] Preferably, the screening device includes a base, a screening box, a vibrating motor, a support plate, screening plates, a mounting plate, and screens. The screening box is mounted on the upper surface of the base via multiple sets of support legs, and the vibrating motor is mounted on the lower surface of the screening box. Multiple sets of support plates are respectively arranged on the left and right ends of the screening box, and mounting plates are respectively arranged on the left and right ends of the multiple sets of screening plates. Screens with different aperture sizes are respectively installed on the upper surfaces of the multiple sets of screening plates. According to the screening requirements, the screening plates with screens of different aperture sizes are inserted into the screening box in order of aperture size. The position of the screening plates is limited by the cooperation of the support plate and the mounting plate. During the screening process, the vibrating motor is turned on to transmit power through the screening box to the multiple sets of screening plates, causing the screens on the multiple sets of screening plates to vibrate, thereby assisting the soil screening process, making the soil on the multiple sets of screens evenly distributed, facilitating the weighing device to obtain accurate data, and improving the practicality of the device.
[0008] Preferably, the device also includes a frustum-shaped groove and a sealing strip. A frustum-shaped groove is provided on the upper surface of the screening plate. The top diameter of the frustum-shaped groove is larger than the bottom diameter of the frustum-shaped groove. The screen is installed at the bottom of the frustum-shaped groove. A sealing strip is provided on the outer edge of the upper surface of the frustum-shaped groove. The sealing strip seals the gap between the upper and lower sets of adjacent screening plates, reducing the leakage of dust from the gap between the two sets of screening plates during the screening process, reducing pollution to the operating environment, and improving data accuracy. The frustum-shaped groove also assists in receiving the soil screened off the upper screening plate, reducing the possibility of soil getting stuck in the gap due to relative displacement caused by the vibration between the upper and lower sets of screening plates when the vibrating motor is running, thus improving the practicality of the device.
[0009] Preferably, the dustproof device includes a nut, a smooth rod, a screw, a sealing cover, and a rotating handle. A nut is installed on the upper surface of the screening box, the smooth rod passes through the nut, a rotating handle is connected to the upper surface of the smooth rod, a screw is connected to the lower part of the smooth rod, and a sealing cover is connected to the lower surface of the screw. The sealing cover provides auxiliary sealing to the frustum-shaped groove on the uppermost screening plate, reducing the pollution of the operating environment caused by dust generated during vibration. The smooth rod allows the sealing cover to be freely adjusted in height to accommodate different numbers of screening plates. When it is necessary to remove or place a screening plate, the sealing cover is raised to the top of the screening box, and the rotating handle is rotated to connect the screw to the smooth rod, thereby fixing the position of the sealing cover and preventing it from falling and affecting the removal or placement of the screening plates, thus improving the practicality of the device.
[0010] Preferably, the weighing device includes weighing holes, two sets of weighing plates, support arms, and pressure sensors. Each set of support plates has a set of weighing holes at its front and rear ends, and the weighing holes are inclined. The lower part of the weighing holes is connected to the outer side of the screening box. A set of support arms is inclinedly installed at the front and rear ends of the side of the weighing plates, and a pressure sensor is installed on the upper end of the support arms. The support arms on the two sets of weighing plates are inclinedly inserted into the weighing holes on the same horizontal plane, and pushed upwards until the pressure sensors lift the plates. The mass of the screening plates is weighed by multiple sets of pressure sensors, thereby calculating the mass change of the screening plates themselves and obtaining soil quality data. Data can be obtained without the operator removing the screening plates and dumping the soil, reducing the labor intensity of the operator.
[0011] Preferably, the auxiliary device includes an electromagnet, a limiting hole, a limiting rod, and a magnet. Multiple sets of electromagnets are vertically arranged on the rear end face of the screening box, with the height of each set of electromagnets being the same as the height of multiple sets of support plates. Multiple sets of limiting holes are arranged on the left and right end faces of the screening box, located at the midpoint between two sets of weighing holes at the same horizontal height. A limiting rod is installed on the middle of the outer side of the weighing plate, and a magnet is installed on the inner side of the limiting rod, allowing the magnet to be inserted into the limiting hole. The electromagnet attracts the position of the screening plate, thereby reducing the displacement of the screening plate after the vibration motor is turned on. By pushing the magnet on the limiting rod into the corresponding limiting hole and making the magnet contact and attract with the inner end face of the limiting hole, the position of the weighing plate is fixed, reducing data errors during the pressure sensor weighing process and improving the practicality of the device.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the soil sample is screened in multiple stages by a screening device, the screening device is dustproofed by a dustproof device to reduce the pollution of the operating environment caused by the overflow of smoke and dust during the screening process, and the various soil masses in the screening device are weighed quickly by a weighing device, so that soil data can be obtained without the operator pouring out the soil, thus improving the practicality of the device.
