Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a portable sand and gravel aggregate powder content detector. Background Technology

[0002] A stone powder content analyzer is an instrument specifically designed to detect the stone powder content. Its core function is to quickly and accurately detect the proportion of particles with a diameter of less than 0.075mm (i.e., stone powder) in aggregates using scientific methods, ensuring that the materials meet national standards and engineering specifications, thereby guaranteeing the quality stability of building materials and the safety of engineering structures.

[0003] When testing the stone powder content in sand and gravel aggregates, the stone powder content analyzer mainly uses the methylene blue test method. The principle is to continuously add methylene blue solution to a suspension made by mixing aggregates and water. The methylene blue will be adsorbed by the powder in the fine aggregates, causing the minerals to react with the reagent and change color. By observing the color change, the mineral content can be determined.

[0004] However, when the stone powder content detector moves, the stirring blades are in an open position, making them extremely susceptible to collisions with external objects. These collisions can cause local deformation of the stirring blades, affecting their subsequent normal use and precise mixing. This can have a potential negative impact on the accuracy and efficiency of the entire stone powder content detection. Therefore, a portable sand and gravel aggregate stone powder content detector is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a portable sand and gravel aggregate powder content detector. This design effectively solves the problem that when the powder content detector is moved, its stirring blade is in an open position, which makes it very susceptible to collisions with external objects, causing local deformation of the stirring blade and negatively impacting the accuracy and efficiency of the overall powder content detection in subsequent use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a detector, a dual coordinate system support fixedly connected to the detector, a motor fixedly connected to the dual coordinate system support, a storage assembly coaxially fixedly connected to the motor, a column groove provided in the storage assembly, and a stirring rod assembly slidably connected in the column groove;

[0007] The stirring rod assembly includes a main rod, a rubber block is fixedly connected to the lower end of the main rod, a stackable stirring blade assembly is fixedly connected to the rubber block, and a compression limiter is provided on the rubber block, which constrains the stacked stirring blade assembly.

[0008] Preferably, the dual coordinate system support includes a test rod, which is fixedly connected to the detector. A connecting buckle is slidably connected to the test rod, and a support rod is slidably connected to the connecting buckle. The support rod is fixedly connected to the motor and is placed perpendicular to the test rod. A positioning bolt for fixing the support rod and the test rod is threaded onto the connecting buckle.

[0009] Preferably, the storage component includes a hollow rod with a connecting groove at its upper end. The output shaft of the motor is connected to the connecting groove. A fixing screw is threaded onto the hollow rod on the side of the connecting groove. The column groove is located below the connecting groove. A slot is provided at the lower end of the hollow rod. An elastic clamp is fixedly connected in the slot. A locking clamp is surrounded around the outside of the elastic clamp.

[0010] Preferably, there are multiple elastic clamps, which are distributed at equal angles within the groove. The interior of each elastic clamp has a frustum-shaped hole. The locking clamp includes a metal clamp, and both ends of the metal clamp are threadedly connected to a self-tightening bolt.

[0011] Preferably, the stirring blade assembly includes a fixed lug, which is fixedly connected to the rubber block. A fixing pin is rotatably connected to the fixed lug, and the stirring blade body is fixedly connected to the fixing pin. A spring is sleeved on the fixing pin, and the spring exerts an upward torsional force on the stirring blade body. A slot for a compression limiter is provided between the stirring blade body and the rubber block.

[0012] Preferably, the stirring blade body is provided with a through hole.

[0013] Preferably, the compression limiter includes a fixed ring, which is fixedly connected to the main rod. The fixed ring is provided with a compression spring, and the compression spring is provided with a movable ring. The movable ring is slidably connected to the main rod.

[0025] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see the appendix Figure 1-7 This embodiment discloses a portable sand and gravel aggregate powder content detector, which includes a detector 1. A dual coordinate system support is fixedly connected to the detector 1. A motor 4 is fixedly connected to the dual coordinate system support. A storage component 5 is coaxially fixedly connected to the motor 4. A column groove 52 is provided inside the storage component 5. A stirring rod assembly 6 is slidably connected inside the column groove 52.

[0027] The top surface of detector 1 is a horizontal support platform. Detector 1 has a built-in wire connected to motor 4. Detector 1 has an external control button, which can control the start and stop of motor 4. A dual-coordinate system bracket is installed on the top of the detection platform. The dual-coordinate system bracket has vertical and horizontal adjustment freedom. The dual-coordinate system bracket adjusts the position and height of motor 4. The output shaft of motor 4 is vertically downward and coaxially connected to the storage component 5. The middle part of the storage component 5 has a groove 52 for storing the stirring rod assembly 6. When the device is not in use, the stirring rod assembly 6 retracts into the storage component 5. When in use, the stirring rod assembly 6 is pulled down. The lower end of the storage component 5 will fix the stirring rod assembly 6 after it moves. In this way, the rotation of the storage component 5 will drive the synchronous rotation of the stirring rod assembly 6.

[0028] The stirring rod assembly 6 includes a main rod 61, with a rubber block 63 fixedly connected to the lower end of the main rod 61. A foldable stirring blade assembly 64 is fixedly connected to the rubber block 63. A compression limiter 62 is provided on the rubber block 63, which constrains the folded stirring blade assembly 64.

[0029] The stirring rod assembly 6 includes a main rod 61. At the lower end of the main rod 61 are four equally angled rubber blocks 63. Each rubber block 63 is connected to a stirring blade assembly 64. The stirring blade assembly 64 includes two fixing lugs 641, located on opposite sides of each rubber block 63. A fixing pin 642 is rotatably connected to the inner side of each rubber block 63, and a spring-loaded spring 643 is fixedly connected to the outer side of each fixing pin 642. Figure 4 and Figure 7 As shown, the spring 643 exerts an upward torsional force on the stirring blade body 644. Under no external force, the stirring blade body 644 and the fixed lug 641 are placed horizontally. When the device needs to be folded up, the stirring blade body 644 needs to be rotated downward. The stirring blade body 644 drives the fixed pin 642 to rotate downward. Then the stirring blade body 644 rotates downward to a vertical position, reducing the space occupied by the stirring blade body 644, thereby preventing the stirring blade body 644 from being damaged by collision. After the stirring blade body 644 rotates downward, there is a gap between the stirring blade body 644 and the rubber pad. If the limiting rod 625 in the compression limiter 62 is inserted into this gap, there will be no room for movement on the inner side of the stirring blade body 644, thereby limiting the degree of freedom of the stirring blade body 644 to rotate upward and preventing the stirring blade body 644 from automatically opening after folding.

[0030] The movable ring 624 inside the compression limiter 62 is fitted onto the main rod 61. The inner diameter of the movable ring 624 is 1.2 times the outer diameter of the main rod 61. The movable ring 624 can slide freely on the main rod 61. A compression spring 623 and a fixed ring 621 are connected below the movable ring 624. The fixed ring 621 is fixedly connected to the main rod 61 and provides support to the bottom of the compression spring 623, so that the compression spring 623 exerts an upward elastic force on the movable ring 624 after compression. The limiting rod 625 is fixedly connected to the movable ring 624. The rod 625 moves vertically in sync with the moving ring 624. The lower part of the limiting rod 625 passes through the guide hole 622 and then through the fixed ring 621. A baffle is provided below the limiting rod 625. The size of the baffle is larger than the size of the guide hole 622. This can prevent the limiting rod 625 from detaching from the guide hole 622. At the same time, when the baffle is close to the bottom of the fixed ring 621, the bottom of the limiting rod 625 is located above the stirring blade body 644, thus avoiding interference between the limiting rod 625 and the stirring blade body 644.

[0031] Storage component 5 includes a hollow rod 51, with a column groove 52 and a connecting groove 53 on the inner side of the hollow rod 51. A fixing screw 54 is screwed onto the inner side of the hollow rod 51, and a clamp is fixedly connected to the inner side of the hollow rod 51. A metal hoop 56 is provided on the inner side of the hollow rod 51, and a self-tightening bolt 57 is screwed onto the inner side of the metal hoop 56. The central axis of the hollow rod 51 is on the same straight line as the central axis of the main rod 61. The inner side of the column groove 52 is in close contact with the outer side of the main rod 61, the inner side of the connecting groove 53 is in close contact with the outer side of the motor 4 main shaft, and one end of the fixing screw 54 is in contact with the outer side of the motor 4 main shaft. The design of the inner groove 52 of the hollow rod 51 being in close contact with the outer side of the main rod 61, and the connecting groove 53 being in close contact with the outer side of the motor 4 main shaft, ensures the stability and precision of the connection between components, reduces shaking and displacement caused by loose connections during use, and makes the operation of the entire device more stable and reliable. The setting of one end of the fixing screw 54 being in close contact with the outer side of the motor 4 main shaft allows the fixing screw 54 to effectively fix the relative position between the motor 4 main shaft and the hollow rod 51 through a spiral connection, preventing the main shaft of the motor 4 from separating or loosening from the hollow rod 51 due to vibration or other reasons during operation, thereby ensuring that the power of the motor 4 can be stably transmitted to the subsequent mechanical components.

[0032] like Figure 3As shown, several elastic clamps 55 are provided, and the multiple elastic clamps 55 are evenly distributed in a circular array. The inner side of the elastic clamp 55 is a frustum cut, with the diameter of the hole being larger at the top and smaller at the bottom. The outer side of the elastic clamp 55 is in close contact with the inner side of the metal hoop 56. Part of the metal hoop 56 is exposed on the outer side of the hollow rod 51. The included angle between the self-tightening bolt 57 and the metal hoop 56 is 90°. The arrangement of the metal hoop 56 and the self-tightening bolt 57 allows the metal hoop 56 to be fastened to the outer side of the clamp by adjusting the self-tightening bolt 57. The self-tightening bolt 57 applies pressure to the elastic clamp 55 by tightening the metal hoop 56, causing the elastic clamp 55 to clamp the main rod 61 inward, thereby keeping the main rod 61 and the hollow rod 51 fixed. When the hollow rod 51 rotates, it can drive the main rod 61 to rotate smoothly.

[0033] The overall workflow of this utility model is as follows: When using the device, the test rod 2 is installed on the detector 1, and then the container containing the stone powder sample is placed on the upper surface of the detector 1. Next, the relative positions of the connecting buckle 3 and the test rod 2 are adjusted to adjust the height of the motor 4. Then, the main shaft of the motor 4 is inserted into the connecting groove 53. A fixed connection is formed between the main shaft of the motor 4 and the hollow rod 51 by rotating the fixing screw 54. The detector 1 controls the start of the motor 4, causing the main shaft of the motor 4 to rotate, which in turn drives the receiving assembly 5 to rotate. The rotation of the receiving assembly 5 drives the stirring rod assembly 6 to rotate, thereby causing the stirring blade body 644 to stir the liquid in the container. The through hole 645 allows the fluid to form a more complex flow path on both sides of the stirring blade body 644, thereby enhancing the mixing effect. After the stirring operation is completed, the self-tightening bolt 57 can be rotated to reduce the radial pressure of the metal clamp 56 on the clamping plate. The stirring blade body 644 is then rotated to change its orientation. Move the main rod 61 backward and upward, so that it penetrates into the column groove 52. After the main rod 61 has moved a certain distance, the hollow rod 51 will apply pressure to the moving ring 624, causing the moving ring 624 to drive the limiting rod 625 to move downward, while squeezing the compression spring 623, causing the compression spring 623 to deform. The guide hole 622 plays a guiding and limiting role in the movement of the limiting rod 625, so that the limiting rod 625 can be accurately inserted into the gap formed between the rubber block 63 and the stirring blade body 644 in the fixed ear seat 641. At this time, even if the stirring blade body 644 is subjected to the elastic force generated by the recovery deformation of the spring 643, it cannot rotate and is thus stored. Turn the self-tightening bolt 57 again to make the metal hoop 56 contract and squeeze the clamping plate, so that the main rod 61 is fixed in the column groove 52 by the clamping plate, so that the components of the device no longer have relative displacement, completing the storage, making it convenient to carry, and reducing the risk of damage to the stirring blade assembly 64 during the carrying process.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
