[0002] In cement production and engineering applications, the uniformity and representativeness of sampling directly determine the accuracy of test results and are key to controlling the core properties of cement such as strength and stability. A search revealed a Chinese patent with authorization number CN222913193U, which discloses an automatic sampler for cement testing, including a handle and a drive mechanism. The handle has a sampling tube on its left side, with a sampling hole at the left end of the outer arc surface of the sampling tube. A retaining ring is located in the middle of the inner arc surface of the sampling tube, and a rotating column is rotatably connected inside the retaining ring. The left end of the outer arc surface of the rotating column is respectively... Equipped with a spiral blade and a baffle cylinder, the baffle cylinder being located to the left of the spiral blade, both of which are in contact with the inner arc surface of the sampling tube; a drive mechanism is respectively located inside the handle and at the right end of the sampling tube, and the drive mechanism is fixedly connected to the right end of the rotating column; a storage battery is installed inside the handle. This automatic cement sampler automatically samples cement at a specified depth, reducing the amount of cement from other locations entering the sampling device during the sampling process, ensuring correct cement sampling, accelerating the cement sampling speed, and improving the accuracy of cement test results.

[0003] The automatic sampler for cement testing in the aforementioned patent has the following shortcomings: Although it achieves automatic sampling through a drive mechanism to improve efficiency and accuracy, it has obvious limitations in use because it relies on electrical equipment and requires battery power. In outdoor construction sites or remote cement storage points without external power, if the battery is depleted and cannot be recharged in time, the sampler will not work directly, which severely limits its application scenarios. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cement testing sampler.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cement testing sampler includes a hollow rod, one end of which is fixedly connected to a holding tube. A rotating rod is rotatably sleeved on the middle of the end of the holding tube near the hollow rod. A bearing adapted to the rotating rod is fixedly sleeved on the middle of the holding tube. A sampling bucket is fixedly connected to the end of the rotating rod inside the hollow rod. A sector plate is fixedly connected to the end of the rotating rod inside the holding tube. Two square rods are fixedly connected to the sector plate near the edge of the holding tube. A circular hole adapted to the square rod is opened on the sector plate. A limiting plate is fixedly connected to the end of the two square rods away from the hollow rod. A protruding rod is fixedly connected to the middle of the other side of the limiting plate.

[0006] Preferably, the other ends of the two square rods are fixedly connected to the same base plate, and the other end of the base plate is fixedly connected to a bending rod, which includes a straight rod and a diagonal rod. Springs are sleeved on both square rods between the limiting plate and the fan-shaped plate.

[0007] Preferably, a U-shaped sliding rod is fixedly connected to the inner wall of the gripping cylinder near the hollow insert rod, and the U-shaped sliding rod is compatible with the bending rod.

[0008] Preferably, a rotating rod is rotatably sleeved on the middle of the side of the gripping cylinder away from the hollow insert rod, and a bearing adapted to the rotating rod is fixedly sleeved on the hollow insert rod. A toggle rod is fixedly connected to one end of the rotating rod inside the gripping cylinder, and the toggle rod is adapted to the protruding rod. A crank handle is fixedly connected to the other end of the rotating rod.

[0009] Preferably, two springs are fixedly connected to the inner wall of the hollow insert, and one end of the middle part of each spring is fixedly connected to the rotating rod.

[0010] Preferably, the sampling barrel has a material inlet, and the hollow rod has a sampling port, which is offset from the material inlet, and the outer wall of the hollow rod also has scale lines.

[0011] The beneficial effects of this utility model are as follows: By employing a combination of a crank handle, a protruding rod, a square rod, a bent rod, a rotating rod, a spring, and a sampling bucket, the hollow insert rod is inserted into the hollow insert by hand holding the handle. Turning the crank handle aligns the sampling port with the material inlet, allowing cement to enter the sampling bucket. As the crank handle continues to rotate, the sampling bucket and rotating rod automatically reset. This effectively solves the problems mentioned in the background technology, eliminating reliance on a power source. No batteries or external power supply are required. The purely mechanical transmission design allows for manual operation at any time, ensuring rapid sampling even in the event of a sudden power outage or equipment failure. This guarantees uninterrupted cement testing while balancing sampling efficiency and result accuracy. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-4 A cement testing sampler includes a hollow rod 1, with a holding tube 2 fixedly connected to one end of the hollow rod 1. A rotating rod 3 is rotatably sleeved in the middle of the end of the holding tube 2 near the hollow rod 1. A bearing adapted to the rotating rod 3 is fixedly sleeved in the middle of the holding tube 2. A sampling bucket 5 is fixedly connected to the end of the rotating rod 3 inside the hollow rod 1. A sector plate 7 is fixedly connected to the end of the rotating rod 3 inside the holding tube 2. Two square rods 701 are fixedly connected to the edge of the sector plate 7 near the holding tube 2. A round hole adapted to the square rods 701 is opened on the sector plate 7. A limiting plate 703 is fixedly connected to the end of the two square rods 701 away from the hollow rod 1. A protruding rod 704 is fixedly connected to the middle of the other side of the limiting plate 703.

[0016] In this utility model, the other ends of the two square rods 701 are fixedly connected to the same base plate 705, and the other end of the base plate 705 is fixedly connected to a bending rod 706, which includes a straight rod and an inclined rod. The two square rods 701 are each fitted with a spring 702 between the limiting plate 703 and the fan-shaped plate 7.

[0017] In this utility model, a U-shaped slide rod 201 is fixedly connected to the inner wall of the holding cylinder 2 near the hollow insert rod 1, and the U-shaped slide rod 201 is adapted to the bending rod 706. The U-shaped slide rod 201 and the bending rod 706 work together to realize the retraction of the protruding rod 704, thereby separating it from the actuating rod 602.

[0018] In this utility model, a rotating rod 6 is rotatably sleeved on the middle of the side of the gripping cylinder 2 away from the hollow insert rod 1, and a bearing adapted to the rotating rod 6 is fixedly sleeved on the hollow insert rod 1. A toggle rod 602 is fixedly connected to one end of the rotating rod 6 inside the gripping cylinder 2, and the toggle rod 602 is adapted to the protruding rod 704. A crank handle 601 is fixedly connected to the other end of the rotating rod 6. By rotating the crank handle 601, the rotation of the fan-shaped plate 7 and the rotating rod 3 can be driven.

[0019] In this invention, two springs 4 are fixedly connected to the inner wall of the hollow insert rod 1, and one end of the middle of each spring 4 is fixedly connected to the rotating rod 3. By setting the springs 4, the rotating rod 3 and the sampling bucket 5 will act on the springs 4 when they rotate, which facilitates the subsequent automatic reset.

[0020] In this utility model, the sampling bucket 5 has a material inlet 501, and the hollow insert rod 1 has a sampling port 102. The sampling port 102 is offset from the material inlet 501, and the outer wall of the hollow insert rod 1 also has a scale line 101. The scale line 101 makes it easy to determine the depth of the sampling bucket 5 inserted into the cement.

[0021] Working principle: When using this device, one end of the sampling bucket 5 of the hollow insert rod 1 is inserted into the cement. The insertion depth can be determined by the scale line 101. During insertion, due to the misalignment of the material inlet 501 and the sampling port 102, cement cannot enter the sampling bucket 5. When the required depth is reached, the crank handle 601 is turned to allow the cement to enter the sampling bucket 5. Figure 3 When the handle is rotated clockwise as shown, the actuating lever 602 will squeeze the protruding rod 704, causing the sector plate 7, the rotating rod 3, and the sampling bucket 5 to rotate. During this process, the material inlet 501 and the sampling inlet 102 coincide, allowing cement from the outside to enter the sampling bucket 5. At the same time, the two springs 4 will be wound. When the rotation is complete, the bending rod 706 will contact the U-shaped sliding rod 201. As the U-shaped sliding rod 201 squeezes the bending rod 706, the limiting plate 703 is compressed, and the protruding rod 704 separates from the actuating lever 602. At this time, under the action of the springs 4, the rotating rod 3 and the sampling bucket 5 will quickly return to their original positions, allowing the sampling bucket 5 of the hollow insert rod 1 to be removed from the cement. By rotating the crank handle 601 again, the cement sample can be taken out. This allows for sampling of cement at different depths without the need for electrical equipment, reducing the weight of the entire device and making it easy to carry.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
