Description

Technical Field

[0001] This utility model relates to the field of manufactured sand production technology, specifically a device for controlling the content of stone powder in manufactured sand. Background Technology

[0002] During the production of manufactured sand, screening is required. The screened manufactured sand has a low powder content, which may render it unusable. Stone powder needs to be added to the manufactured sand. However, manually adding stone powder may result in the powder content not reaching the optimal level or exceeding the standard. It is impossible to accurately control the stone powder content, which affects the quality of manufactured sand production. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by designing a device for controlling the content of manufactured sand and gravel powder.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A device for controlling the content of manufactured sand and gravel powder, comprising:

[0006] Fixed base;

[0007] A container for storing manufactured sand;

[0008] Stone powder storage box, used to store stone powder from manufactured sand;

[0009] The partition baffle is fixedly connected to the fixed base. The partition baffle is installed vertically, and the manufactured sand container and the stone powder container are located on both sides of the partition baffle.

[0010] A stone powder content control component, which is used to convey stone powder, is disposed on a partition baffle.

[0011] The stone powder content control component first weighs the manufactured sand container, then transfers the stone powder from the stone powder container to the manufactured sand container. Weighing the manufactured sand container containing both manufactured sand and stone powder allows for precise control of the stone powder content in the manufactured sand, thus improving the quality of manufactured sand production.

[0012] Furthermore, the stone powder content control component includes a fixed top plate, which is fixedly installed on one side of the partition baffle and located above the manufactured sand holding box. Weighing plates are fixedly installed on both sides of the manufactured sand holding box. Two hydraulic cylinders are installed on the fixed base, and the two hydraulic cylinders are respectively located on both sides of the manufactured sand holding box. A load-bearing plate is installed at the top of the piston rod of the hydraulic cylinder, and a weighing sensor is installed on the surface of the load-bearing plate.

[0013] Furthermore, the stone powder content control component also includes a negative pressure pipe that passes through a partition baffle. A hopper is connected to the fixed top plate. One end of the negative pressure pipe is connected to the hopper. A lifting top plate is provided on the other side of the partition baffle. The lifting top plate is located above the stone powder holding box. A suction hopper is connected to the lifting top plate. A suction hose is connected to the suction hopper. The top end of the suction hose is fixedly connected to the other end of the negative pressure pipe.

[0014] Furthermore, the partition baffle is provided with a vertical sliding groove, and a lifting slider is slidably connected in the vertical sliding groove. One side of the lifting top plate is fixedly connected to the lifting slider. A multi-stage telescopic cylinder is installed on the fixed base, and the telescopic end of the multi-stage telescopic cylinder is fixedly connected to the lifting top plate.

[0015] The lifting roof panel is raised and lowered by a multi-stage telescopic cylinder. The lifting slide block and vertical slide groove guide the lifting roof panel to raise and lower it in a straight line, thus preventing the position of the lifting roof panel from deviating.

[0016] Furthermore, a sealing gasket is connected to the bottom surface of the lifting top plate and the fixed top plate, and a diagonal tie rod is fixedly connected to one side of the top of the fixed top plate, with one end of the diagonal tie rod fixedly connected to the partition baffle.

[0017] The strength of the fixed top plate is increased by the diagonal tie rods, which prevents the fixed top plate from bending and deforming and improves its service life. The openings of the manufactured sand holding box and the stone powder holding box are sealed by the sealing gaskets, which improves the airtightness and prevents dust from overflowing and polluting the air.

[0018] Furthermore, the sidewalls of the load-bearing plate are equipped with omnidirectional ball bearings.

[0019] Compared with existing technologies, this technical solution has the following beneficial effects:

[0020] 1. The hydraulic cylinder drives the load-bearing plate and weighing sensor to rise, which in turn drives the manufactured sand container to rise. After the manufactured sand container is raised, the weighing sensor detects the weight of the manufactured sand inside. At the same time, the top plate is fixed to seal the opening of the manufactured sand container. The required stone powder content is calculated based on the weight of the manufactured sand, and the stone powder is transported into the manufactured sand container. The stone powder content can be accurately controlled by weighing, which improves the quality of manufactured sand production.

[0021] 2. The stone powder in the stone powder holding box is sucked out through the negative pressure pipe, suction hose and suction hopper and transported to the manufactured sand holding box, which facilitates the transportation of stone powder and the control of stone powder content in the manufactured sand.
