[0002] Artificial sand refers to sand processed by sand making machines and other ancillary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. Artificial sand is the product obtained after the stone passes through the coarse crusher and the fine crusher, and then is screened.

[0003] At present, when screening artificial sand, the artificial sand is generally poured onto the screen, and the screen is vibrated to screen the artificial sand. In this process, the artificial sand to be screened is directly poured, resulting in a large amount of artificial sand accumulating on the screen, which makes the driving pressure of the driving device of the screen larger, and also affects the service life of the screen, which is inconvenient to use. At the same time, when the artificial sand is dynamically screened, the fine particles in the artificial sand will generate a lot of dust, affecting the production environment. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 4 As shown, the screening module for producing machine-made sand in this embodiment includes a base frame 1, and four support blocks 2 are installed in a rectangular array on the upper end of the base frame 1. Shock-absorbing springs 3 are installed above the support blocks 2, and a screening shell 4 is installed on the upper ends of the shock-absorbing springs 3. A screening frame 5 is installed obliquely inside the screening shell 4, and a screen 6 is detachably installed on the screening frame 5. The screen 6 is installed by bolts, which is convenient for replacing the screen 6. A vibration motor 7 is installed on the front end surface of the screening shell 4, and the vibration motor 7 is used to drive the screen 6 to vibrate, so as to facilitate the screening of the machine-made sand. A dust suction component is installed at the rear end of the screening shell 4, and the dust suction component is used to absorb dust generated by screening the machine-made sand to prevent dust from spreading. A protective cover 9 is detachably installed above the screening shell 4, and the protective cover 9 is used to protect the screening shell 4. An adding bucket 10 is installed on the upper end of the protective cover 9, and a uniform feeding component is arranged above the adding bucket 10. The uniform feeding component is used to uniformly discharge the machine-made sand to be screened, so as to prevent the machine-made sand from falling too much and generating a large starting pressure on the vibration motor 7.

[0021] Specifically, the dust collection assembly includes an exhaust fan 801, a branch pipe 802, a connecting pipe 803, an exhaust pipe 804 and a dust bag 805. A plurality of branch pipes 802 are installed at the rear end of the screening shell 4 above the screen 6. A connecting pipe 803 is installed at the rear end of the branch pipes 802. An exhaust pipe 804 is installed on the surface of the connecting pipe 803. An exhaust fan 801 is installed at the rear end of the screening shell 4 below the branch pipes 802. The output end of the exhaust fan 801 is connected to the exhaust pipe 804. A dust bag 805 is detachably installed at the output end of the air duct 804. By starting the exhaust fan 801, the suction force generated by the exhaust fan 801 adsorbs the dust inside the screening shell 4 through the exhaust duct 804, the connecting pipe 803 and the branch pipe 802. The adsorbed dust enters the dust bag 805, and the dust bag 805 collects the dust. The air is discharged from the gap on the dust bag 805, which effectively prevents the spread of dust during the screening of machine-made sand and prevents dust from polluting the production environment.

[0022] Furthermore, a first discharge port 12 is arranged on one side of the screening shell 4, and a second discharge port 13 is arranged on the lower end of the screening shell 4. The first discharge port 12 is used to discharge stones that have not passed through the screen 6, and the second discharge port 13 is used to discharge machine-made sand that has passed through the screen 6.

[0023] Furthermore, the uniform material unloading assembly includes a storage box 1101, a material unloading box 1102, a driving motor 1103, a rotating rod 1104, a toggle plate 1105 and a support rod 1106. The upper end of the bottom frame 1 outside the support block 2 is equipped with a supporting rod 1106 in a rectangular array. The upper ends of the supporting rods 1106 are jointly equipped with the storage box 1101, the material unloading box 1102 is installed at the lower end of the storage box 1101, and the driving motor 1103 is installed at the front end of the material unloading box 1102. The output end of the driving motor 1103 is located at the material unloading box 1101. A rotating rod 1104 is installed inside, and a plurality of toggle plates 1105 are installed on the surface of the rotating rod 1104 in a circular array. The rotating rod 1104 is driven to rotate by the driving motor 1103. The toggle plates 1105 on the surface of the rotating rod 1104 can toggle the machine-made sand to be screened. The machine-made sand enters between the toggle plates 1105 and is discharged as the toggle plates 1105 rotate, so that the machine-made sand falls evenly, effectively preventing a large amount of machine-made sand from falling directly on the screen 6 and damaging the screen 6 and the vibration motor 7.

[0024] Furthermore, the size of the discharge box 1102 is smaller than that of the adding bucket 10 , and the discharge box 1102 is located directly above the adding bucket 10 , so that the machine-made sand dropped from the discharge box 1102 can completely enter the adding bucket 10 , thereby preventing the machine-made sand from accidentally falling outside the adding bucket 10 .

[0025] Furthermore, fixed blocks 14 are installed at the front and rear parts of the upper end of the screening shell 4, and the protective cover 9 is slidably installed on the surface of the fixed block 14 through a sliding groove. The fixed block 14 and the sliding groove are both T-shaped, and the protective cover 9 is installed on the surface of the fixed block 14 by sliding, which is convenient for removing the protective cover 9 and replacing the internal screen 6.

[0026] The method of using this embodiment is as follows: when the screening module is used, the machine-made sand to be screened is stored in the storage box 1101, and the machine-made sand enters between the toggle plates 1105 on the surface of the rotating rod 1104, and the driving motor 1103 is controlled to rotate. The driving motor 1103 drives the toggle plate 1105 to rotate through the rotating rod 1104. As the toggle plate 1105 rotates, the machine-made sand is discharged, and the machine-made sand falls onto the screen 6 through the adding bucket 10. At the same time, the vibration motor 7 drives the screen 6 to vibrate, and the screen 6 screens the machine-made sand. In this process, the suction force generated by the exhaust fan 801 absorbs the dust inside the screening shell 4 through the exhaust pipe 804, the connecting pipe 803 and the branch pipe 802. The adsorbed dust enters the dust removal bag 805, and the dust removal bag 805 collects the dust. The air is discharged from the gap on the dust removal bag 805 to achieve dust removal. The screened machine-made sand can be discharged from the first discharge port 12 and the second discharge port 13.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
