Technical Field

[0001] The utility model relates to the technical field of sampling devices for detection, in particular to a sampling device for detection of construction engineering materials. Background Art

[0002] Construction materials refer to various materials used in construction projects, and are also an important part of building buildings. The quality of construction materials is directly related to the safety and service life of buildings. In order to ensure the quality of construction projects, material quality testing is an indispensable link. There are many types of construction materials, including natural stone, cement, concrete, sand, paint, etc. When sand is used in construction, it is necessary to sample the sand, and then test the water content, particle size, bulk density and mud content of the sand to determine whether the sand quality is qualified.

[0003] A Chinese utility model patent with publication number CN219608477U discloses a sampling device for concrete sand and gravel, which belongs to the technical field of building material sampling and includes an inner cylinder, an outer cylinder, a rotating shaft, a sleeve rod and a driving motor; the upper end of the inner cylinder is connected to the output end of the driving motor by means of the rotating shaft, the middle part of the inner cylinder has a containing cavity, and the side wall of the inner cylinder is provided with a flow hole connected to the containing cavity; the outer cylinder is movably sleeved on the outer side of the inner cylinder, and the lower end of the outer cylinder is open; the upper end of the outer cylinder is connected to the sleeve rod, the sleeve rod is sleeved on the outer side of the rotating shaft, and the sleeve rod moves along the length direction of the rotating shaft to pull the outer cylinder to cover or open the flow hole.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: after sampling, the above-mentioned device cannot directly pour the sample into the test tube, but needs to pour the sample into an additional container, and then use a funnel to pour the sample into the test tube for testing, which increases the operation steps and reduces work efficiency. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a sampling device for detecting construction engineering materials.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a sampling device for detecting construction materials, comprising a sampling barrel, a feed port is penetrated through the outer wall of the sampling barrel near the top thereof, a lower hopper is fixedly connected to the bottom of the sampling barrel, a bottom cover is detachably connected to the outer wall of the sampling barrel near the bottom thereof, and the top of the bottom cover is in contact with the lower end of the discharge port of the lower hopper.

[0007] By adopting the above technical solution, when it is necessary to sample and test the sand, the tester first puts the sampling bucket into the sand pile, and the sand will enter the sampling bucket through the feed port to complete the sampling. Then the tester can align the sampling bucket with the test tube and open the bottom cover. The sand will flow into the test tube through the discharge port of the lower hopper, which is convenient for subsequent testing work. There is no need to use other auxiliary tools for operation, which is conducive to reducing the operating steps and thus improving work efficiency.

[0008] Furthermore, the lower hopper includes a connecting ring fixed to the bottom of the sampling barrel and a silica gel funnel fixed to the bottom of the connecting ring, and the diameter of the silica gel funnel gradually decreases from top to bottom.

[0009] By adopting the above technical solution, when the sand is mixed with larger stones and other impurities, since the silicone funnel has a certain deformation ability, it is helpful to reduce the probability of larger stones and other impurities blocking the discharge port of the hopper, thereby ensuring the smooth discharge of samples.

[0010] Furthermore, a plurality of notches are provided at the intersection between the side wall and the bottom of the silica gel funnel.

[0011] By adopting the above technical solution, the notch cooperates with the discharge port, thereby increasing the width of the discharge port and further reducing the probability of larger stones and other debris clogging the discharge port of the lower hopper.

[0012] Furthermore, two threaded holes are symmetrically provided on the outer wall of the connecting ring, and the connecting ring is threadedly connected to the bottom cover by a hexagon socket bolt, the hexagon socket bolt passes through the bottom cover and is gap-matched with the bottom cover, the hexagon socket bolt is threadedly connected to the threaded hole, and a receiving groove for accommodating the nut end of the hexagon socket bolt is provided on the outer wall of the bottom cover.

[0013] By adopting the above technical solution, it is convenient for the inspector to detachably connect the bottom cover to the sampling barrel, so that it is convenient for the inspector to open the bottom cover and take out the inspection sample.

[0014] Furthermore, a fixing plate is arranged above the sampling barrel, a motor is fixed on the top of the fixing plate, a mounting rod is fixed on the bottom of the fixing plate, the output shaft end of the motor is fixed to the upper end of the mounting rod, a connecting plate is fixed on the bottom of the mounting rod, a slide groove is opened on the bottom of the connecting plate, a slider slidingly matched with the slide groove is fixed on the top of the sampling barrel, a connecting pipe is sleeved on the mounting rod, an outer barrel is fixed on the lower end of the connecting pipe, the outer barrel is a hollow structure, and the inner wall of the outer barrel fits with the outer wall of the sampling barrel.

[0015] By adopting the above technical solution, since the moisture on the outer surface of the sand pile is easily evaporated, affecting the accuracy of the test data, the tester starts the motor, and after the motor works, it drives the installation rod and the sampling bucket to move synchronously. The tester manually puts the outer bucket and the sampling bucket into the sand pile synchronously, and then turns off the motor. The outer bucket covers and protects the feed port of the sampling bucket to reduce the probability of dried sand entering the sampling bucket. The tester then lifts the connecting pipe and the outer bucket upward, and the sand will flow into the feed port of the sampling bucket to complete the sampling, ensuring that the sampling bucket collects the sand inside the sand pile, thereby improving the accuracy of the measurement data; the sampling bucket is slidably connected to the connecting plate, which is convenient for the tester to disassemble and clean the sampling bucket later.

[0016] Furthermore, a movable plate is provided below the fixed plate, a mounting tube is fixed to the bottom of the movable plate, a mounting plate is provided in the mounting tube, an outer wall of the mounting plate is fitted with an inner wall of the mounting tube, the mounting plate is fixedly connected to a mounting rod, a spring is provided in the mounting tube, an upper end of the spring is fixed to the bottom of the mounting plate, a lower end of the spring is fixed to the inner bottom wall of the mounting tube, the spring is sleeved on the mounting rod, the mounting rod passes through the mounting tube and slidably cooperates with the mounting tube, the mounting rod also passes through the movable plate and slidably cooperates with the movable plate, and the bottom of the mounting tube is fixed and connected to the upper end of the connecting pipe.

[0017] By adopting the above technical solution, after the sampling is successful, the inspector pushes the movable plate downward, so that the connecting pipe and the outer barrel move downward synchronously, and the outer barrel covers and protects the feeding port of the sampling barrel again, reducing the probability of other sand entering the sampling barrel. Then, the inspector takes the entire device out of the sand pile, lifts the movable plate upward, and gradually approaches the fixed plate. The mounting tube moves upward to squeeze the spring. Since the mounting plate is fixedly connected to the mounting rod, the spring is limited and compressed by the mounting plate, and the outer barrel also moves upward, so that the outer barrel is separated from the sampling barrel. The bottom of the outer barrel is close to the top of the sampling barrel, which is convenient for the inspector to loosen the hexagon socket bolts with a hexagonal wrench and open the bottom cover, so as to directly pour the sample in the sampling barrel into the test tube, and then tighten the hexagon socket bolts with a hexagonal wrench to close the bottom cover. Then the inspector releases the force on the movable plate. Since the spring is elastic, under the action of elastic force, the movable plate, the mounting barrel and the outer barrel will move downward, and the outer barrel continues to cover the feeding port of the sampling barrel, which is convenient for the later sampling work.

[0018] Furthermore, the top of the outer barrel is a conical structure, and the outer wall of the sampling barrel is provided with a plurality of grooves.

[0019] By adopting the above technical solution, the conical design is conducive to reducing the resistance of the outer barrel during the upward movement; the groove is conducive to increasing the friction between the inspector's hand and the sampling barrel, making it easier for the inspector to take out the sampling barrel.

[0020] Furthermore, a magnetic block is embedded on the top of the sliding block.

[0021] The adoption of the above technical solution is helpful to improve the stability between the sampling barrel and the connecting plate.
