Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coal sampling technology, specifically relating to a coal pile stratified sampling device. Background Technology
[0002] As an important component of the global energy structure, the quality of coal directly affects energy utilization efficiency, economic benefits and environmental protection. In the process of coal production, trade and utilization, coal pile sampling is a key link in assessing coal quality. During the accumulation process, due to particle size sorting, moisture migration and oxidation, there are significant differences in the coal quality of different layers. When sampling coal piles, it is usually necessary to collect coal from different layers for analysis.
[0003] However, traditional coal pile sampling methods mainly rely on using tools such as shovels and sampling spades to sample the surface or random points. This method can only achieve surface or single-point sampling and cannot sample different layers of coal within the coal pile at once, which brings a lot of trouble to the sampling work. To address this issue, the applicant proposes a coal pile layered sampling device. Utility Model Content
[0004] The purpose of this invention is to provide a coal pile layer sampling device that can conveniently and simultaneously sample coal from different layers inside the coal pile in one operation through a simple method, without the need for repeated sampling operations, effectively saving sampling time, improving sampling efficiency, and bringing more convenience to the sampling work.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A coal pile stratified sampling device, comprising:
[0007] An outer cylinder mechanism and a sampling mechanism assembled inside the outer cylinder mechanism, and a feeding mechanism assembled inside the sampling mechanism;
[0008] The outer cylinder mechanism includes a insert cylinder, and a feed inlet is provided on one side of the insert cylinder;
[0009] The sampling mechanism includes a sampling cylinder rotatably installed inside the insert, the sampling cylinder having a storage cavity inside, and a sampling port corresponding to the inlet having a sampling port on one side of the storage cavity;
[0010] The material feeding mechanism includes a pull rod that is slidably installed inside the storage cavity. A fixing post is fixedly installed on one side of the pull rod, and a feeding blade corresponding to the sampling port is slidably installed on one side of the fixing post.
[0011] Preferably, the feeding blade has a toothed groove on one side, and the feeding blade extends out of the feed inlet.
[0012] Preferably, the top of the pull rod extends out of the insert, and a handle is fixedly installed on one side of the pull rod.
[0013] Preferably, the inside of the feeding blade is provided with a movable groove for the fixed pile to slide, and a thrust spring is fixedly installed between the movable groove and the fixed pile.
[0014] Preferably, a fixing rod extending out of the insertion tube is fixedly installed on the top of the sampling tube, and a grip ring is fixedly installed on the top of the fixing rod.
[0015] Preferably, the top of the insert has a groove for the fixed rod to slide, and the bottom of the insert has a pointed cone fixedly installed.
[0016] Preferably, handles are fixedly installed on both sides of the insert, and the handles are covered with anti-slip sleeves.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] (1) The present invention is equipped with an outer cylinder mechanism and a sampling mechanism that work together. When the insert is inserted into the coal pile, the sampling cylinder can be rotated to align the sampling port with the feed port. This allows coal from different layers in the coal pile to be simultaneously introduced into the corresponding storage chambers in the sampling cylinder. This allows for convenient and simple operation to simultaneously sample coal from different layers inside the coal pile without repeated sampling. This effectively saves sampling time, improves sampling efficiency, and brings more convenience to the sampling work.
[0019] (2) This utility model is equipped with a material feeding mechanism, which can move up and down by pulling the pull rod during the sampling process. This allows the material feeding blade to feed the coal at the feed inlet, making it convenient to disperse the nearby coal. This allows the coal to quickly enter the storage chamber through the feed inlet, avoiding the coal in the coal pile from being squeezed and unable to flow into the storage chamber, thus improving the sampling effect.

[0031] Example 1:
[0032] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a coal pile stratified sampling device includes:
[0033] The outer cylinder mechanism 1, the sampling mechanism 2 assembled inside the outer cylinder mechanism 1, and the feeding mechanism 3 assembled inside the sampling mechanism 2;
[0034] The outer cylinder mechanism 1 includes a tube 11, and a feed inlet 13 is provided on one side of the tube 11;
[0035] The sampling mechanism 2 includes a sampling cylinder 21 rotatably installed inside the insert 11. The sampling cylinder 21 has a storage chamber 22 inside, and a sampling port 23 corresponding to the feed inlet 13 is opened on one side of the storage chamber 22.
[0036] The feeding mechanism 3 includes a pull rod 31 that is slidably installed inside the storage cavity 22. A fixing post 32 is fixedly installed on one side of the pull rod 31, and a feeding blade 33 corresponding to the sampling port 23 is slidably installed on one side of the fixing post 32.
[0037] As can be seen from the above, when using this device, it is carried to the coal pile, and the insert 11 is inserted into the coal pile from top to bottom. The sampling tube 21 is rotated so that the sampling port 23 is aligned with the feed port 13. This allows coal from different layers in the coal pile to enter the sampling port 23 through the feed port 13. It can be conveniently introduced into multiple storage chambers 22 at the same time. The storage chambers 22 can conveniently store coal from different layers. The coal from different layers inside the coal pile can be sampled at the same time without repeated sampling operations. This effectively saves sampling time, improves sampling efficiency, and brings more convenience to the sampling work.
[0038] When the sampling port 23 is aligned with the feed inlet 13 by rotating the sampling cylinder 21, the feeding blade 33 can be driven to rotate synchronously, aligning the feeding blade 33 with the feed inlet 13. Through elasticity, the feeding blade 33 can automatically extend into the sampling port 23. The feeding blade 33 is triangular in shape, allowing the wider part to engage at the sampling port 23, while the sharp part extends out of the insert cylinder 11 from the feed inlet 13. By operating the pull rod 31 to move up and down, the feeding blade 33 can perform feeding operations on the coal at the feed inlet 13, which facilitates the dispersal of nearby coal and allows the coal to quickly enter the storage chamber 22 through the feed inlet 13. This avoids the coal in the coal pile being squeezed and unable to flow into the storage chamber 22, thus improving the sampling effect.
[0039] After sampling is completed, by rotating the sampling cylinder 21 in the opposite direction, the sampling port 23 can be misaligned with the feed port 13, which facilitates sealing of the sampling port 23 and prevents coal from spilling out of the storage chamber 22 when it is removed. At the same time, when the sampling cylinder 21 is rotated, the edge of the feeding blade 33 can be pressed against the inner wall of the feed port 13, which can push the feeding blade 33 to slide along the fixed post 32, so that the feeding blade 33 can be retracted into the storage chamber 22 without affecting the rotation operation of the sampling cylinder 21.
[0040] Depend on Figure 5 and Figure 7 It can be seen that a toothed groove 35 is provided on one side of the feeding blade 33, and the feeding blade 33 extends out of the feed inlet 13.
[0041] As can be seen from the above, when the feeding blade 33 moves up and down, the toothed groove 35 can be used to break up the nearby coal particles, which can improve the flow effect of the coal and allow the coal particles to be quickly introduced into the storage chamber 22.
[0042] For details, please refer to Figure 2 As shown, the top of the pull rod 31 extends out of the insert 11, and a handle 34 is fixedly installed on one side of the pull rod 31.
[0043] As can be seen from the above, by using the handle 34, the pull rod 31 can be easily pulled up and down, which can easily drive the material-dispersing blade 33 to disperse the coal near the feed inlet 13.
[0044] For details, please refer to Figure 7 As shown, the inside of the feeding blade 33 is provided with a movable groove 36 for the fixed pile 32 to slide, and a thrust spring 37 is fixedly installed between the movable groove 36 and the fixed pile 32.
[0045] As can be seen from the above, by extending the fixed pile 32 into the movable groove 36, the feeding blade 33 can be retracted into the storage chamber 22. By the pushing action of the thrust spring 37, when the sampling port 23 is aligned with the feed port 13, the feeding blade 33 can be pushed to extend into the feed port 13.
[0046] Example 2:
[0047] refer to Figure 2 As shown, a fixing rod 24 extending out of the insertion tube 11 is fixedly installed on the top of the sampling tube 21, and a grip ring 25 is fixedly installed on the top of the fixing rod 24.
[0048] As can be seen from the above, by holding the grip ring 25 and rotating it, the fixed rod 24 can be used to drive the sampling tube 21 to rotate synchronously, which makes it convenient to align the sampling port 23 with the feed port 13 and perform misalignment operations.
[0049] refer to Figure 1 , Figure 4 and Figure 5 As shown, the top of the insert 11 is provided with a groove 16 for the fixed rod 24 to slide, and the bottom of the insert 11 is fixedly installed with a pointed cone 12.
[0050] As can be seen from the above, when the sampling tube 21 is rotated, the fixing rod 24 can slide along the slide groove 16, which makes it easy to rotate the sampling tube 21 90° and position it, bringing more convenience to the rotation operation. The pointed cone 12 makes it easier to insert the insertion tube 11 into the coal pile, which is convenient for sampling coal at different layers.
[0051] refer to Figure 4 As shown, handles 14 are fixedly installed on both sides of the insert 11, and the handles 14 are covered with anti-slip sleeves 15.
[0052] As can be seen from the above, the insert 11 can be easily pressed into the coal pile by holding the handle 14. The anti-slip sleeve 15 can increase the friction between the hand and the insert 11, making it less likely to slip when pressing the insert 11.
[0053] 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.
