Description

Technical Field

[0001] The utility model relates to the technical field of aggregate detection, in particular to an aggregate detection device. Background Technique

[0002] The particle gradation of aggregates is a key technology for manufacturing concrete. For a concrete with poor particle gradation of aggregates, during the construction process, it is inevitable that the paste, aggregates, and water will segregate, making the pouring and molding difficult. Finally, it will lead to "honeycombing, holes, and pitted surfaces" in the concrete finished product, with low strength and poor durability. Therefore, for the key materials of aggregate building materials, it is necessary to standardize its particle gradation to ensure the production and manufacturing of concrete. Otherwise, it will cause huge technical and economic losses to the concrete project.

[0003] In the utility model patent with the publication number of CN217425087U, a concrete aggregate detection device for municipal engineering is disclosed, which includes a fixed base. The top of the fixed base is movably connected with a vibration device. A vibration space capable of placing multiple layers of square-hole sieves is formed inside the vibration device. A weight detection device is arranged at the top of the vibration device. After vibration, each square-hole sieve can move to the weight detection device for weighing and move out of the vibration space after weighing.

[0004] However, when this utility model is in use, it requires the user to manually slide the fastener of the square-hole sieve to compact and fix the square-hole sieve, which increases the labor intensity of the user and has a poor use effect. Content of the Utility Model

[0009] Beneficial effects

[0010] The utility model provides an aggregate detection device, which has the following beneficial effects:

[0011] 1. Starting the motor can drive the threaded rod to rotate and move downward. By moving the threaded rod downward, the cover plate can be driven to press and fix the sieve box, eliminating the need for manual fixation and reducing the labor intensity of the user.

[0018] Through those skilled in the art, all the electrical components in this case are electrically connected to their adapted power supplies, and appropriate controllers should be selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, the electrical connection should be completed with reference to the sequence of the electrical components working successively in the following working principle.

[0019] Example: According to the attached instructions Figure 1It can be seen that during use, the dried aggregate is poured into the tray 18, and the dried aggregate is weighed by the electronic scale 17.

Starting the vibration motor 20 can drive the vibration plate 19 to vibrate. By vibrating the vibration plate 19, the sieve box 7 can be driven to vibrate. The aggregate with a smaller particle size falls downward along the sieve mesh 6, and the aggregate with a larger particle size is intercepted by the sieve mesh 6. After the vibration ends, by reversing the motor 13, the threaded rod 12 can be driven to rotate reversely and move upward. By moving the threaded rod 12 upward, the cover plate 9 can be driven to move upward away from the sieve box 7. Then the aggregate in the sieve box 7 and the bottom box 4 is weighed and measured in sequence. The aggregate weighing method is manual weighing, and the aggregate weighing method is common knowledge for those skilled in the art and will not be elaborated here.
