Description
Technical Field
[0001] This utility model belongs to the technical field of phosphate mining equipment, and specifically relates to a uniform sampling device for phosphate stockpiles. Background Technology
[0002] Phosphate ore sampling refers to the process of taking representative samples from phosphate ore stockpiles or underground phosphate mines according to certain methods and procedures. In relatively large or formal phosphate ore stockpiles, machines can usually be used for sampling. However, for smaller phosphate ore stockpiles or those with incomplete facilities, manual sampling is still required. Ordinary sampling shovels and forks are not only time-consuming and labor-intensive, but also pose safety and dust problems during the phosphate ore mining process. Furthermore, due to long-term accumulation, the quality of surface phosphate ore differs from that inside. Therefore, a portable device is needed that can perform multiple and uniform samplings of phosphate ore stockpiles. Utility Model Content
[0003] The purpose of this utility model is to provide a uniform sampling device for phosphate rock piles. Its advantages are that it is equipped with multiple sample collection boxes, which can sample phosphate rock at different locations and heights in the pile. At the same time, the detachable sampling tube is convenient for installation and replacement, and it can also collect samples from inside the phosphate rock pile, avoiding the influence of surface phosphate rock on the overall quality.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a uniform sampling device for a phosphate rock stockpile, comprising a box body, a handle fixedly connected to the rear of the box body, a box cover fitted on the top of the box body, a collection hole opened on the top of the box cover, a sleeve fixedly connected to the center of the top of the box cover, the inner wall of the sleeve penetrating the box cover, a limit clip provided on the top of the inner wall of the sleeve, a sampling tube base fixedly connected to the front of the surface of the sleeve, a sampling device fitted onto the inner wall of the sampling tube base, the sampling device comprising a sampling tube, buckles provided on both sides of the rear of the sampling tube, a sampling inlet hole opened on the front of the top of the sampling tube, a sliding groove opened on the front of the bottom of the sampling tube, a sampling outlet hole opened at the bottom of the rear of the sampling tube, the sampling outlet hole communicating with the sliding groove, a slider slidably connected to the inner wall of the sampling tube, a scraper fixedly connected to the top of the rear of the slider, and a limit clip fixedly connected to the bottom of the rear of the slider.
[0005] The above technical solution allows for easy sample removal by separating the lid and body. The sampling device can also be replaced individually if damaged, reducing operating costs. Different sizes of sampling devices can be selected for different samples, facilitating portability and installation. Moving the slider pushes the surface sample out of the sampling cylinder, allowing the desired sample to enter through the top inlet. Pulling the slider back causes the scraper and slider to push the sample out of the outlet, allowing it to fall into the box. This avoids low overall sample quality due to surface samples.
[0006] The present invention is further configured such that slots are provided on both sides of the sampling tube base, and the slots and buckles are engaged with each other.
[0007] The above technical solution is adopted: the sampling tube is tightly connected to the sampling tube base by the interlocking of the slot and the buckle, which prevents the sampling tube from falling off, and at the same time ensures that the inlet and outlet ports are in the correct positions.
[0008] The present invention is further configured such that a rotating base is provided at the bottom of the inner wall of the box, a rotating shaft is rotatably connected to the inner wall of the rotating base, the surface of the rotating shaft is rotatably connected to the inner wall of the sleeve, and a plurality of connecting strips are uniformly fixedly connected to the surface of the rotating shaft, and a collection box is sleeved on the surface of the connecting strips.
[0009] The above technical solution is adopted: the rotation of the shaft drives the rotation of the collection box. When the collection box is full, the next collection box can be switched to continue sampling, so as to avoid the impact of the product evaluation due to the small number of samples. At the same time, the setting of multiple collection boxes can sample products in different areas of the storage yard to ensure that the samples are representative.
[0010] The present invention is further configured such that a boss is fixedly connected to the top of the rotating shaft, and a rotating handle is rotatably connected to the surface of the boss, and the rotating handle is engaged with a limiting card.
[0011] The above technical solution is adopted: by rotating the handle, the shaft is driven to rotate, and the shaft drives the collection box to rotate. When the handle and the limit card are engaged, the collection box is positioned directly below the collection hole, which facilitates the receipt of samples and avoids sample spillage due to rotational misalignment.
[0012] The present invention is further configured such that the surface of the slider is fitted with two rubber rings.
[0013] The above technical solution is adopted: by using a rubber ring, it is ensured that the sample inside the sampling tube can be completely pushed out when the slider slides inside the sampling tube, so as to avoid residue.
[0014] The present invention is further configured such that a push rod is provided behind the limiting piece.
[0015] The above technical solution is adopted: by setting a push rod, it is convenient to manually move the slider, and in conjunction with the sliding groove at the bottom of the sampling cylinder, it is prevented from pushing the slider out of the sampling cylinder, which would cause sampling failure.
[0016] The present invention is further configured such that a collection hole cover is fitted on the surface of the sleeve, and the collection hole cover is slidably connected to the top of the box cover.
[0017] The above technical solution involves rotating the collection hole cover to prevent the sample from spilling out of the collection box, while also preventing other items from falling in and contaminating the sample.
[0018] In summary, this utility model has the following beneficial effects:
[0019] 1. This utility model allows for convenient removal of the obtained sample by separating the lid and the body of the box. At the same time, the sampling device can be replaced separately when damaged, which reduces the cost of use. Different sizes of sampling devices can also be selected according to different samples, making it easy to carry and install.
[0020] 2. This utility model moves the slider to the front end of the sampling tube, pushing the surface sample out of the sampling tube. At this time, the required sample enters the sampling tube from the top inlet hole. Pulling the slider back again, the scraper and the slider together push the sample out of the outlet hole, so that the sample falls into the collection box. This avoids the overall sample quality being low due to the surface sample. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.
[0028] Example 1:
[0029] refer to Figure 1 A uniform sampling device for phosphate rock stockpiles includes a box body 1, a handle 2 fixedly connected to the rear of the box body 1, a box cover 3 fitted onto the top of the box body 1, a collection hole 4 opened on the top of the box cover 3, a sleeve 5 fixedly connected to the center of the top of the box cover 3, the inner wall of the sleeve 5 penetrating the box cover 3, a limit clip 6 provided on the top of the inner wall of the sleeve 5, a sampling tube base 7 fixedly connected to the front of the surface of the sleeve 5, and a sampling device 8 fitted onto the inner wall of the sampling tube base 7. By separating the box cover 3 from the box body 1, the obtained sample can be easily taken out. At the same time, the sampling device 8 can be replaced separately when damaged, reducing the cost of use. Different sizes of sampling devices 8 can also be selected according to different samples, making it easy to carry and install.
[0030] The sampling device 8 includes a sampling cylinder 801. Buckles 802 are provided on both sides of the rear of the sampling cylinder 801. A sample inlet 803 is provided at the front of the top of the sampling cylinder 801. A sliding groove 804 is provided at the front of the bottom of the sampling cylinder 801. A sample outlet 805 is provided at the bottom of the rear of the sampling cylinder 801, and the sample outlet 805 communicates with the sliding groove 804. A slider 806 is slidably connected to the inner wall of the sampling cylinder 801, and a scraper 808 is fixedly connected to the top of the rear of the slider 806. A limiting piece 809 is fixedly connected to the bottom of the slider 806. By moving the slider 806 to the front end of the sampling cylinder 801, the surface sample is pushed out of the sampling cylinder 801. At this time, the required sample enters the sampling cylinder 801 from the top inlet hole 803. When the slider 806 is pulled back, the scraper 808 and the slider 806 together push the sample out of the outlet hole 805, so that the sample falls into the box 1. This avoids the overall sample quality being low due to the surface sample.
[0031] refer to Figure 1 , Figure 2The sampling tube base 7 has slots 701 on both sides. The slots 701 and buckles 802 are engaged with each other. Through the engagement of the slots 701 and buckles 802, the sampling tube 801 is tightly connected to the sampling tube base 7, preventing the sampling tube 801 from falling off. At the same time, the inlet hole 803 and the outlet hole 805 are in the correct positions.
[0032] refer to Figure 3 A rotating base 9 is provided at the bottom of the inner wall of the box body 1. A rotating shaft 10 is rotatably connected to the inner wall of the rotating base 9. The surface of the rotating shaft 10 is rotatably connected to the inner wall of the sleeve 5. A connecting strip 11 is fixedly connected to the surface of the rotating shaft 10. A collection box 12 is sleeved on the surface of the connecting strip 11. The rotation of the rotating shaft 10 drives the rotation of the collection box 12. When the collection box 12 is full, the next collection box 12 can be switched to continue sampling, so as to avoid the impact of the product evaluation due to the small number of samples. At the same time, the setting of multiple collection boxes 12 can sample products in different areas of the storage yard to ensure that the samples are representative.
[0033] refer to Figure 3 A boss 13 is fixedly connected to the top of the rotating shaft 10. A rotating handle 14 is rotatably connected to the surface of the boss 13. By rotating the rotating handle 14, the rotating shaft 10 is driven to rotate, and the rotating shaft 10 drives the collection box 12 to rotate. When the rotating handle 14 and the limiting card 6 are engaged with each other, the collection box 12 is exactly below the collection hole 4, which is convenient for receiving the sample and avoids the sample from spilling out due to rotational misalignment.
[0034] refer to Figure 4 The surface of the slider 806 is fitted with two rubber rings 807. By fitting the rubber rings 807, it is ensured that when the slider 806 slides in the sampling cylinder 801, the sample in the sampling cylinder 801 can be completely pushed out to avoid residue.
[0035] Brief description of usage: The sample can be easily taken out by separating the lid 3 and the body 1. The sampling device 8 can also be replaced separately if it is damaged, which reduces the cost of use. Different sizes of sampling devices 8 can be selected according to different samples, which is convenient for carrying and installation.
[0036] refer to Figure 4 A push rod 810 is provided behind the limiting piece 809. By setting the push rod 810, it is convenient to manually move the slider 806. In conjunction with the sliding groove 804 at the bottom of the sampling cylinder 801, the slider 806 is prevented from being pushed out of the sampling cylinder 801, which would cause sampling failure.
[0037] refer to Figure 1 , Figure 2The sleeve 5 is fitted with a collection hole cover 15, which is slidably connected to the top of the box cover 3. By rotating the collection hole cover 15, the collection hole 4 is covered, preventing the sample from spilling out of the collection box 12 and also preventing other items from falling in and contaminating the sample.
[0038] Brief description of the usage process: When sampling, the sampling tube 801 is inserted into the phosphate rock pile. At this time, the phosphate rock on the surface will also enter the sampling tube 801. By moving the slider 806 to the front end of the sampling tube 801, the sample on the surface of the phosphate rock pile is pushed out of the sampling tube 801. Then, the phosphate rock sample inside the phosphate rock pile enters the sampling tube 801 from the top inlet hole 803. Pull the slider 806 back again. The scraper 808 and the slider 806 together push the sample out of the outlet hole 805, so that the sample falls into the collection box 12. This avoids the overall sample quality being low due to the surface sample.
