Description

Technical Field

[0001] The utility model relates to the technical field of building material processing screening devices, in particular to a building material processing screening device. Background Art

[0002] Building materials processing is a general term for materials used in civil engineering and construction engineering. It can be divided into structural materials, decorative materials and some special materials. Building materials are a general term for materials used in civil engineering and construction engineering. Building materials products include three major categories: building materials and products, non-metallic minerals and products, and inorganic non-metallic new materials. They are widely used in construction, military industry, environmental protection, high-tech industries and people's lives. They have high strength, good durability, good insulation, sound insulation, and energy-saving performance, wide environmental adaptability, durability and good adaptability to use functions.

[0003] At present, in the existing technology, most of the building materials processing screening devices perform screening through ordinary shaking. However, during shaking screening, it is easy for building material particles to get stuck to each other, thereby clogging the screen and affecting the working efficiency of the screen. In view of this, we propose a building materials processing screening device. Utility Model Content

[0004] The main purpose of the utility model is to provide a building material processing screening device, which can solve the problems raised in the above technical background.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a building material processing screening device, comprising a device body, wherein a screening device is arranged inside the device body, and the screening device comprises:

[0006] A screening box, wherein a screening bracket is fixedly connected to the inner wall of the screening box, a sliding hole is provided inside the screening box, and a screening disc is slidably connected to the inner wall of the screening box.

[0007] Preferably, a guide column is fixedly connected to the bottom surface of the screening disk, the surface of the guide column is slidably connected to the inner wall of the sliding hole, the inner wall of the sliding hole is fixedly connected to one end of a spring, and the other end of the spring is fixedly connected to the surface of the screening disk.

[0008] Preferably, a mounting ring is fixedly connected to the inner wall of the screening disc, and a screening net is clamped on the inner wall of the mounting ring.

[0009] Preferably, the device body comprises a shell, the inner wall of the shell is provided with a sliding ring, the inner wall of the sliding ring is slidably connected to the surface of the screening device, and the inner wall of the shell is provided with a guide slideway.

[0010] Preferably, a motor bracket is fixedly connected to the inner wall of the shell, a motor is fixedly connected to the upper surface of the motor bracket, an output shaft of the motor is fixedly connected to one end of an eccentric connecting rod, and the other end of the eccentric connecting rod is rotatably connected to the bottom surface of the screening device.

[0011] Preferably, a pressing protrusion is fixedly connected to the surface of the sliding ring.

[0012] The utility model provides a material screening device for building material processing, which has the following beneficial effects:

[0013] (1) The building material processing screening device has an eccentric connecting rod. When the motor drives the screening device to move through the eccentric connecting rod, the eccentric connecting rod drives the screening device to rotate and shake inside the device body, thereby screening the building material raw materials inside the screening device. Compared with ordinary rotary screening, the eccentric connecting rod rotary shaking screening efficiency is higher and the screen is not easily blocked.

[0014] (2) The building material processing screening device has a guide column. When the motor drives the screening device to move through the eccentric connecting rod, the guide column and the pressing protrusion are squeezed against each other, thereby pushing the screening plate to move upward, thereby stretching the spring, causing the spring to accumulate force, causing the screening plate to vibrate back and forth, thereby accelerating the screening of the raw materials inside the screening device.
