Description

Technical Field

[0001] The utility model belongs to the technical field of mining and smelting, and relates to a sampling device under a sieve plate. Background Art

[0002] The flotation machines in the flotation area of ​​a ore dressing workshop of a certain ore dressing plant are installed in a sunken style. The upper part of the main shaft of the flotation machine, the pulley, the motor, etc. are located above the steel platform, and the flotation machine tank body, the lower part of the main shaft, the dispersion cover and other parts are located below the steel platform. The platform surface is fully covered with a steel grating plate of one square meter. The grating plate has square holes with a hole diameter of 2cm*8cm. The flotation operator can observe the foaming situation of each flotation machine through the steel grating plate.

[0003] When it is necessary to take samples of the flotation machine pulp or concentrate foam, the staff on duty need to uncover the entire steel sieve plate to expose the flotation machine to be sampled before taking samples. The steel sieve plate is heavy and cannot be lifted or moved by one person, and at least two people are required to operate it. After the steel sieve plate is uncovered, the staff takes samples at the edge of the flotation tank, which has a high safety risk. The sampling tool is a small bucket sampling, the sample quantity is large at one time, and the representativeness is poor. Utility Model Content

[0004] The utility model aims to provide a sampling device under a sieve plate to solve the problems existing in the prior art, which solves the problems that when the existing flotation machine is used for bubbling sampling, the operation risk for operators is high and the difficulty is great, and the sampling tool is a small bucket sampling, the sample amount is large and the representativeness is poor.

[0005] To this end, the utility model adopts the following technical solutions:

[0006] A sampling device under a sieve plate comprises a box body, a box cover is provided on the top of the box body, and the two are movably connected via a linkage shaft, a handle is provided on the side of the box body, one end of the handle is fixedly connected to the box body and the other end is U-shaped, a pull rod is provided on the top of the box cover, a hook is provided on the top of the pull rod, a fixing ring is passed through the handle near the top, and the two are fixedly connected, and the hook is hung on the handle after passing through the fixing ring.

[0007] Furthermore, two inserting tubes arranged side by side are provided on the top side of the box body, and the linkage shaft passes through the inserting tubes and is fixedly connected to the box cover.

[0008] Furthermore, the length of the box body does not exceed 2 cm, and the width does not exceed 8 cm.

[0009] The beneficial effects of the utility model are:

[0010] During the use of the utility model, operators no longer need to open the steel sieve plate when sampling, which ensures the safety of the sampling operation and makes the sampling operation simpler and more convenient, saves sampling operation manpower and labor intensity, improves sampling work efficiency, and the sample box is small in size and can be sampled multiple times to ensure sample uniformity.

[0013] In the figure, 1-box body, 1a-insertion tube, 2-box cover, 3-handle, 4-pull rod, 4a-hook, 5-linkage shaft, 6-fixing ring. DETAILED DESCRIPTION

[0014] The technical solution of the utility model is described below in conjunction with the accompanying drawings and implementation methods.

[0015] like Figure 1 As shown, a sampling device under a grid sieve plate comprises a box body 1, specifically, the length of the box body 1 does not exceed 2 cm, and the width does not exceed 8 cm; a box cover 2 is provided on the top of the box body 1, and the two are movably connected through a linkage shaft 5; a handle 3 is provided on the side of the box body 1, one end of the handle 3 is fixedly connected to the box body 1, and the other end is U-shaped; a pull rod 4 is provided on the top of the box cover 2, and a hook 4a is provided on the top of the pull rod 4, and a fixing ring 6 is passed through the position of the handle 3 near the top, and the two are fixedly connected, and the hook 4a is hung on the handle 3 after passing through the fixing ring 6.

[0016] like Figure 2 As shown, two inserting tubes 1a arranged side by side are provided on the top side of the box body 1, and the linkage shaft 5 passes through the inserting tubes 1a and is fixedly connected to the box cover 2.

[0017] During the use of the utility model, the operator holds the handle 3 and inserts the box body 1 from the hole of the steel grid screen plate. Then, the pull rod 4 is lifted up to open the box cover 2, and the box cover 2 is placed close to the overflow edge of the flotation machine for sampling, or the sample box is directly inserted into the slurry, and the sample enters the box body 1. After the sampling is completed, the pull rod 4 is pushed down to close the box cover 2, and the device is lifted up from the steel grid screen plate by the handle 3, and the sampling operation can be completed in one time.
