Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ore pulp sampling tools in ore dressing fields, in particular to a simple ore pulp sampling spoon. Background Art
[0002] A slurry sampling spoon is a tool used to sample slurry or solid matter from underground ore bodies. It is usually made of stainless steel or other corrosion-resistant materials, with a long handle and a curved spoon head. During the mining process, the spoon head is inserted into the ore body and then pulled out, so that slurry or solid samples can be obtained for analysis and testing. The design and use of slurry sampling spoons vary depending on different mining occasions, such as underground mining, open-pit mining, etc.
[0003] However, in actual use, the following problems are usually encountered: In the mineral processing industry, when technicians need to understand the on-site indicators, they need to sample the slurry at different process stages, and the sampling scenarios at different process stages are very different. At present, the sampling spoons and spoon handles used in the industry are mostly fixed at 180°, which are only suitable for the scene where the sampling spoon can enter the sampling at a vertical angle, and cannot adapt to some more curved sampling scenes. It is not very versatile. In addition, if the slurry flow rate is too fast during sampling, the slurry will instantly fill the sampling spoon, causing the fine-grained components to overflow. The overflow of fine-grained components will cause the sample composition to change due to the lack of overflow components, making it unrepresentative. Summary of the invention
[0004] The main purpose of the utility model is to provide a simple slurry sampling spoon, which can effectively solve the problems mentioned in the background technology that the spoon cannot adapt to some relatively curved sampling scenes and the sample is easy to overflow.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A simple slurry sampling spoon, comprising:
[0007] A sampling spoon, the sampling spoon is cylindrical, and a containing space is provided inside the sampling spoon;
[0008] A sampling port, which is circular and is opened at the bottom of the sampling spoon;
[0009] A rubber disc is located inside the sampling spoon and is hinged to an edge of the sampling port.
[0010] Also includes:
[0011] A connecting piece, the connecting piece is longitudinally fixedly mounted on one side of the sampling spoon;
[0012] A threaded interface, the threaded interface is provided at the top end of the connecting piece, and a circle of internal threads is provided inside the threaded interface;
[0013] A screw, wherein the outer surface of the screw is provided with a circle of external threads, and the screw is threadedly connected to the thread interface;
[0014] A rotating shaft rod, wherein the screw rod is fixedly arranged at the bottom end of the rotating shaft rod;
[0015] A connecting through hole, wherein the connecting through hole is formed at the top end of the rotating shaft rod;
[0016] A telescopic rod, one end of which is connected to the connecting through hole;
[0017] An anti-skid handle is sleeved on the other end of the telescopic rod.
[0018] Also includes:
[0019] A first hinge, the first hinge being installed at the connection between the rubber disc and the sampling spoon;
[0020] A second hinge is installed at the connection between the telescopic rod and the connecting through hole.
[0021] The first hinge and the second hinge are both damping hinges.
[0022] The material of the anti-slip handle is rubber.
[0023] The sampling spoon is made of stainless steel.
[0024] Compared with the prior art, the utility model has the following beneficial effects: the utility model is provided with an adjustable angle and telescopic spoon handle. Targeted adjustments can be made for some relatively tortuous sampling points, and it has universal applicability. In addition, the sampling port is opened at the bottom, and one side of the rubber sheet is hinged thereto to realize the opening and closing function. When sampling, the bottom of the spoon contacts the slurry, and the slurry pushes the rubber disc to enter the spoon. When the sampling is completed and the sampling spoon is pulled back, the slurry that has entered the sampling spoon will be pressed down by gravity, pressing the rubber sheet against the sampling port to seal it and prevent outflow. In this way, the fine-grained components can be effectively prevented from overflowing, thereby preventing a large amount of sample loss. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0033] like Figure 1-4 As shown, a simple slurry sampling spoon comprises: a sampling spoon 1, a sampling port 2, and a rubber disc 3. The sampling spoon 1 is cylindrical, and a containing space is provided inside the sampling spoon 1. The sampling port 2 is circular and is provided at the bottom of the sampling spoon 1. The rubber disc 3 is located inside the sampling spoon 1, and the rubber disc 3 is hinged to an edge of the sampling port 2. The sampling port 2 corresponds to the rubber disc 3. The cylindrical spoon body is about 10 cm high and has a bottom diameter of about 8 cm. The diameter of the sampling port 2 is about 5 cm, and the diameter of the rubber disc 3 is about 6 cm. The diameter of the rubber disc 3 is slightly larger than the diameter of the sampling port 2, which can ensure that the rubber disc 3 is always located inside the sampling spoon 1, that is, above the sampling port 2, effectively preventing the original rubber sheet from falling off.
[0034] In this embodiment, the connecting member 4 is columnar and is longitudinally fixedly installed on one side of the sampling spoon 1. The threaded interface 5 is provided at the top of the connecting member 4, and a circle of internal threads is provided inside the threaded interface 5. The outer surface of the screw rod 6 is provided with a circle of external threads, and the screw rod 6 is threadedly connected with the threaded interface 5. The screw rod 6 is fixedly provided at the bottom end of the rotating shaft rod 7. The connecting through hole 8 is provided at the top of the rotating shaft rod 7. One end of the telescopic rod 9 is connected with the connecting through hole 8. The anti-slip handle 10 is sleeved on the other end of the telescopic rod 9. The first hinge 11 is installed at the connection between the rubber disc 3 and the sampling spoon 1. The second hinge 12 is installed at the connection between the telescopic rod 9 and the connecting through hole 8. The first hinge 11 and the second hinge 12 are both damping hinges. The damping hinge can effectively control the folding speed of the object, making the folding process more stable and slow, which helps to improve the safety of the product. In addition, the damping hinge can provide a certain damping force during the folding process, so that the object can maintain a stable position when reaching a specific angle. By controlling the folding speed and providing damping force, the damping hinge can improve the user experience and make the product operation smoother and more comfortable. When the first hinge 11 is set tight, the folding angle of the rubber disc 3 will be limited by the damping force. The folding angle is preferably within 60 degrees. The unfolding angle within 60 degrees can ensure that when the sampling spoon 1 is pulled back, the rubber disc 3 will be fully pressed by the sample in the spoon that sinks due to gravity, and the rubber disc 3 is pressed back to the sampling port 2 to seal it.
[0035] It should be noted that the utility model is a simple slurry sampling spoon 1. When in use, hold the non-slip handle 10 and put the sampling spoon 1 into the sampling point. If the sampling point channel is long, pull the telescopic rod 9 to adjust it. If the sampling point channel is tortuous, the second hinge 12 can be adjusted to be loose, so that it is convenient to bend the shaft rod 7 and lower it to the sampling point. After that, start sampling. When the slurry passes through the sampling spoon 1, the bottom of the spoon contacts the slurry. The slurry will push the rubber disc 3 open and enter the spoon due to the inertia when it is lowered. When the sampling spoon 1 is completed, lift the sampling spoon 1. Due to the effect of gravity, the slurry will press the original disc to prevent the slurry from leaking and complete the sampling.
[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
