Description

Technical Field

[0001] The utility model relates to the field of screening equipment, in particular to a construction site material screening equipment. Background Art

[0002] Construction materials, such as cement and sand, need to be screened before mixing to separate larger particles such as agglomerates and impurities. Currently, most screening equipment combines a plate screen with a vibrating motor. The vibrating motor generates vibrations that act on the plate screen to separate the materials.

[0003] However, the inclination angle of the existing plate screen is generally fixed when working, and the inclination angle of the plate screen determines the material separation processing time (the longer the material separation processing time, the better the separation effect). Therefore, the inclination angle of the plate screen is adjustable to adapt to materials in different states.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] See also Figure 1 、 Figure 2 and Figure 3 The present invention provides a construction site material screening device comprising a deformable screen 1, at least one active column 2, and multiple passive columns 3 for supporting the screen 1. The screen 1 is constructed of a metal material with a certain degree of elastic deformation, such as elastic steel or an alloy. Each column is connected to the screen 1 at its end. The active column 2 and the multiple passive columns 3 are mounted on a frame 00, which is equipped with a vibration motor 01 for generating vibration force.

[0021] In the initial state, the screen 1 is in a horizontal state, and each column is in a state perpendicular to the screen 1; when the active column 2 is active, it will drive the screen 1 to undergo a partial downward deformation. At this time, the screen 1 has a certain inclination to achieve the discharge of materials. During the use of this application, for some materials that are not easy to separate (such as wet materials), when in use, the equipment is preferably in the initial state, the material to be separated (material that is difficult to screen) falls onto the screen 1, and the equipment is started (the vibration motor 01 produces a vibration effect). Since the screen 1 is in a horizontal state, at this time, the material can be retained on the screen 1 for a long time and sufficient separation work is performed. When discharging is required, it is only necessary to drive the active column 2 to move, so that the screen 1 is deformed (the screen 1 undergoes a partial downward deformation) to form a discharge space. The material will be discharged according to the discharge equipment under its own gravity and vibration effect.

[0022] See also Figure 4 Preferably, a fixing cap 4 is screwed onto the end of each of the columns of the present invention, and an installation space for installing the screen 1 is formed between the two. Through the above-mentioned installation method, when the screen 1 is deformed, the screen 1 will rotate in the horizontal direction (perpendicular to the axis direction of the column) relative to the column.

[0023] The active columns 2 are provided with two groups and are rotatably installed on the same side of the frame 00. When the active columns 2 are in motion, the two groups of active columns 2 rotate relative to each other, so that the screen 1 forms a partially concave material gathering space. Through this material gathering space, the material has a material gathering effect during the discharge process, which facilitates material discharge. A rotating shaft 21 is provided at a predetermined position of the active column 2, and the rotating shaft 21 is installed in the mounting hole of the frame 00. Alternatively, the active column 2 is connected to the frame 00 through a damping torsion device. The rotational resistance is used to enable the active column 2 to maintain a stable state after rotation, avoiding returning to its original position due to the elastic deformation of the screen 1.

[0024] A handle 5 for driving the deformation is provided below the local deformation position of the screen 1. To adjust the screen 1 for local deformation, only the handle 5 needs to be pulled down; when resetting, the handle 5 needs to be pushed up.

[0025] During the screening process, the equipment status can be adjusted at any time according to the difficulty of separating the materials to increase the screening efficiency.

[0026] In summary, the present invention provides a material screening device for a construction site, comprising a deformable screen and at least one active column and a plurality of passive columns for supporting the screen; the screen is selected from a screen structure made of a metal material with a certain elastic deformation, and the metal can be elastic steel or an alloy. The ends of each column are connected to the screen; of course, the active column and the plurality of passive columns are mounted on a frame, and a vibration motor for generating vibration force is mounted on the frame. In the initial state, the screen is in a horizontal state, and each column is in a vertical state relative to the screen; when the active column is activated, it drives the screen to undergo a partial downward deformation, at which time the screen has a certain inclination, realizing the discharge of materials. During use of this application, for some materials that are difficult to separate (such as wet materials), when in use, the device is preferably in the initial state, the material to be separated (material that is difficult to screen) falls onto the screen, and the device is started (the vibration motor produces a vibration effect). Since the screen is in a horizontal state, the material can be retained on the screen for a long time, and sufficient separation work can be performed. When discharging is required, the active column is simply driven to move, causing the screen to deform (partially move downward), forming a discharge space. The material is then discharged from the device under the influence of its own gravity and vibration. This utility model can adjust the device state at any time according to the difficulty of separating the material, thereby increasing the efficiency of screening.

[0027] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
