Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mine sampling, in particular to an automatic sampling device for a down-the-hole drill. Background Art
[0002] Sampling refers to the process of extracting individuals or samples from a population, that is, the process of testing or observing the population. For all cement companies, the control of mine production quality directly affects the process of the entire cement line and the quality of the final product. Therefore, how to control the quality of mine production, especially to grasp the ore quality distribution in advance, is an effective guarantee for the quality of matching production. Therefore, sampling is an indispensable process. However, manual drilling samples are easily disturbed by behavior, resulting in poor representativeness and causing difficulties for subsequent matching production. Setting up a separate sampling machine will increase costs. Utility Model Content
[0003] The utility model aims to solve the above problems, thereby providing an automatic sampling device for a down-the-hole drill with reduced human interference.
[0004] The utility model solves the above problems and adopts the following technical solutions:
[0005] An automatic sampling device for a down-the-hole drill comprises a dust collecting box of the down-the-hole drill, a dust outlet is provided in the middle of the dust collecting box, a dust outlet is connected to the dust outlet, a conical tube is connected to the bottom of the dust outlet tube, an air lock valve is connected to the bottom of the conical tube, a connecting tube is provided at the bottom of the air lock valve, and a dust collecting bag is detachably provided at the lower part of the connecting tube.
[0006] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:
[0007] The dust collecting box of the down-the-hole drill itself is utilized, and there is no need for additional sampling equipment. When the down-the-hole drill is working, the gravity of the powder is used to guide a certain amount of slag foam through the dust outlet pipe through the conical tube and the air lock valve into the dust collecting bag. The conical tube can prevent the powder from adhering to the tube wall. When the drilling rig is resting or sampling is not required, the dust collecting bag is removed and the air lock valve is closed, which will not cause powder leakage.
[0008] As a preferred embodiment, a further technical solution of the utility model is:
[0009] A dust shield is arranged in the dust collecting box and at the lower outer periphery of the dust outlet.
[0010] The inner wall of the dust shield is a smooth structure.
[0011] The dust bags are numbered.
[0012] A plurality of hooks are arranged along the circumferential direction on the lower part of the outer wall of the connecting pipe, and the dust collecting bags are hung on the hooks. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 This is a schematic diagram of the main cross-sectional structure of an embodiment of the utility model;
[0014] Figure 2 This is a schematic diagram of the structure of the dust shield plate inside the dust collecting box of the utility model embodiment;
[0015] The markings in the figure are: dust collecting box 1, dust outlet 2, dust outlet pipe 3, tapered pipe 4, air lock valve 5, connecting pipe 6, dust collecting bag 7, dust shield 8, hook 9. DETAILED DESCRIPTION
[0016] The present invention is further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.
[0017] An automatic sampling device for a down-the-hole drill comprises a dust collecting box 1 of the down-the-hole drill, a dust outlet 2 is provided in the middle of the dust collecting box 1, the dust outlet 2 has a diameter of 30 mm, a dust outlet 3 is connected to the dust outlet 2, a conical tube 4 is connected to the bottom of the dust outlet tube 3, the bottom of the conical tube 4 has a diameter of 70 mm, which can prevent powder from adhering to the tube wall and facilitate material discharge, an air lock valve 5 is connected to the bottom of the conical tube 4, the air lock valve 5 prevents the backflow of powder, a connecting tube 6 is arranged at the bottom of the air lock valve 5, a connecting flange is arranged between the air lock valve 5 and the conical tube 4 and the connecting tube 6, a dust bag 7 is detachably arranged at the lower part of the connecting tube 6, and a plurality of dust bags 7 are preset according to the number of samples to be sampled.
[0018] A dust shield 8 is provided inside the dust box 1 and at the lower outer periphery of the dust outlet 2. The dust shield 8 extends 30 mm inside the dust box 1. The angle between the dust shield 8 and the upper side wall of the dust box 1 is 20°. When the dust box 1 is discharged, part of the powder is intercepted and introduced into the dust bag 7 through the dust outlet pipe 3.
[0019] The inner wall of the dust shield 8 is a smooth structure to prevent powder from sticking.
[0020] The dust collecting bag 6 is provided with a label. Due to sampling requirements, a plurality of dust collecting bags 6 need to be provided to avoid confusion.
[0021] A plurality of hooks 9 are provided along the circumferential direction at the lower portion of the outer wall of the connecting pipe 6 , and the dust collecting bag 7 is hung on the hooks 9 for easy disassembly.
[0022] The dust collecting box of the down-the-hole drill itself is utilized, and there is no need for additional sampling equipment. When the down-the-hole drill is working, the gravity of the powder is used to guide a certain amount of slag foam through the dust outlet pipe through the conical tube and the air lock valve into the dust collecting bag. The conical tube can prevent the powder from adhering to the tube wall. When the drilling rig is resting or sampling is not required, the dust collecting bag is removed and the air lock valve is closed, which will not cause powder leakage.
