Detailed Embodiments

[0031] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model are now described with reference to the accompanying drawings.

[0032] Embodiment 1

[0033] A preferred embodiment of the sand particle screening device for building construction provided by the present utility model is as Figures 1 to 5 shown: A sand particle screening device for building construction includes:

[0034] The fixing frame 1 has a hollow top surface. A support frame 2 is fixedly installed on the top surface of the fixing frame 1. There are three groups of support frames 2, which are sequentially arranged on the bottom surface of the fixing frame 1. A cross frame is fixedly installed between two of the support frames 2. The three installed support frames 2 can play a role in firmly supporting the fixing frame 1, facilitating the stable operation of the entire device;

[0035] The feeding box 3 is fixedly installed on the top surface of the right end of the fixing frame 1;

[0036] Among them, the side surface of the lower end of the feeding box 3 is provided with a discharge port;

[0037] The dispersing assembly 5 is connected to the feeding box 3. The dispersing assembly 5 is connected to a screening assembly 6, and the screening assembly 6 is arranged on the top surface of the fixing frame 1.

[0038] The dispersing assembly 5 includes:

[0039] The motor 51 is arranged behind the feeding box 3. The output end of the motor 51 is fixedly installed with a shaft 52. The front end of the shaft 52 movably penetrates the back surface of the feeding box 3 and extends into the feeding box 3;

[0040] The dispersing rods 53 are fixedly installed on the outer wall of the shaft 52. The number of the dispersing rods 53 is two, and an inclined vibrating plate 54 is arranged below the dispersing rods 53. The vibrating plate 54 is slidably arranged on the inner wall of the feeding box 3, and a cylindrical rod 56 is fixedly sleeved on the vibrating plate 54. The cylindrical rod 56 is rotatably arranged through the feeding box 3, and can rotate relative to the feeding box 3. A first spring 55 is sleeved on the outer wall of the cylindrical rod 56. One end of the first spring 55 is fixedly installed at the end of the cylindrical rod 56, and the other end of the first spring 55 is fixedly installed on the surface of the feeding box 3;

[0041] Among them, the lower end of the vibrating plate 54 penetrates the discharge port of the feeding box 3.

[0042] In the specific implementation process, by starting the motor 51, the shaft 52 can be rotated. By rotating the shaft 52, the dispersing rods 53 can be rotated. The rotating dispersing rods 53 can strike the entering sand grains, break up the sand grains adhered together. At the same time, the dispersing rods 53 will squeeze the vibrating plate 54 during rotation. Under the action of the first spring 56, the vibrating plate 54 can be deflected and vibrated, which can strengthen the vibration of the adhered sand grains and facilitate the subsequent screening work.

[0043] In this embodiment, a motor base 7 is fixedly installed on the lower surface of the motor 51. The motor base 7 is fixedly installed on the back surface of the feeding box 3. By installing the motor base 7, the motor 51 can be stably installed, facilitating the stable operation of the motor 51.

[0044] Embodiment 2

[0045] On the basis of the implementation of the above solution, the screening component 6 includes:

[0046] A screen frame 61 is arranged above the fixed frame 1. The top surface of the right end of the screen frame 61 is fixedly connected to the bottom surface of the lower end of the vibrating plate 54 through a rubber body 62. A blanking plate 4 fixedly installed with the support frame 2 is arranged below the screen frame 61;

[0047] An auxiliary plate 64 is fixedly installed on the top surface of the fixed frame 1. A pin 65 is arranged between the auxiliary plate 64 and the screen frame 61. One end of the pin 65 movably penetrates through a track groove 66 formed on the surface of the auxiliary plate 64 and extends to be fixedly installed on the surface of the screen frame 61.

[0048] In the specific implementation process, the deflection vibration of the vibrating plate 54 can drive the rubber body 62 to drive the screen frame 61 to move repeatedly, so as to realize the screening of the sand grains processed by the dispersing component 5.

[0049] In this embodiment, a second spring 63 is fixedly installed on the right side surface of the screen frame 61. The end of the second spring 63 far from the screen frame 61 is fixedly installed on the side surface of the feed box 3. By arranging the second spring 63, the vibration performance of the screen frame 61 can be increased during the screening work, which is convenient for the screening work and also makes the reciprocating screening effect of the screen frame 61 better.

[0050] Furthermore, half of the track groove 66 is arranged in a straight line shape, and the other half is arranged in an arc shape, and it is in a state of decreasing from right to left. In this way, the screen frame 61 can have an up-and-down undulating vibration during the reciprocating work process, which can not only well avoid the blockage of the screen frame 61, but also vibrate and tumble the sand grains up and down, facilitating uniform screening treatment.

[0051] Working principle: Before the sand grains are fed, start the motor 51, which can make the shaft 52 rotate, so that the dispersing rods 53 installed on the outer wall of the shaft 52 rotate, strike the sand grains entering the feed box 3, and break open the sand grains bonded together. At the same time, under the setting of the first spring 56, the dispersing rods 53 will squeeze the vibrating plate 54 during the rotation process and realize the vibration of the vibrating plate 54, further strengthening the dispersion treatment of the sand grains. After that, the sand grains will enter the screen frame 61. During the repeated vibration of the vibrating plate 54, the rubber body 62 will have the same movement trend, and then can drive the repeated movement of the screen frame 61. Through the setting of the second spring 63 and the cooperation of the pin 65 and the track groove 66, the screen frame 61 can have a slight up-and-down vibration while moving repeatedly, which can better perform uniform screening treatment on the sand grains and also avoid the blockage of the screen frame 61. The screened sand grains will be discharged through the blanking plate 4.

[0052] The above are only illustrative specific embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present utility model shall fall within the scope of protection of the present utility model. Moreover, it should be noted that the components of the present utility model are not limited to the above overall application. Each technical feature described in the specification of the present utility model can be selected and used alone according to actual needs or multiple features can be combined for use. Therefore, the present utility model should logically cover other combinations and specific applications related to the inventive points of this case.
