[0024] 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.
[0025] See also Figure 1-4 The utility model provides a technical solution: a screening device for concrete raw materials, comprising: a box body 1, a screening box 2, a hole 3, a double-shaft motor 4, an eccentric wheel 5, a protective cover 6, a spring steel 7, a dust collecting cover 8, a protective cover 9, a microfiber cloth 10, a protective cover 11, a dust collecting device 12, a support frame 13, a spray head 14, a first pulley 15, a second pulley 16, a connecting belt 17, a single-shaft motor 18, a heating wire 19 and a receiving box 20;
[0026] like Figure 1 , Figure 2 and Figure 3As shown in the figure, the concrete raw material is poured directly into the interior of the screening box 2 from the feeding port on the top of the box body 1, and then the double-axis motor 4 inside the protective cover 6 is opened. The eccentric wheels 5 are connected to the front and rear sides of the double-axis motor 4, so when the double-axis motor 4 is started, the front and rear eccentric wheels 5 can be driven to rotate. Because the double-axis motor 4, the eccentric wheels 5 and the protective cover 6 are inside the screening box 2, the bottom of the screening box 2 is supported by the spring steel 7 inside the box body 1. The spring steel 7 has good elasticity and toughness. Its elasticity can make the spring return to its original state when subjected to external force or stretching. At the same time, it has high toughness and is not easy to break when subjected to large impact or vibration. Therefore, the eccentric wheel 5 The rotation can make the screening box 2, the hole 3, the eccentric wheel 5, the protective cover 6 and the spring steel 7 vibrate inside the box body 1. Secondly, the inner bottom of the screening box 2 is arranged in a slope and a plurality of holes 3 are provided. Therefore, the impurities screened by the concrete on the screening box 2 can directly roll to the right from the inner bottom of the screening box 2 to the right side of the receiving box 20 below the outer side of the box body 1. The raw materials are directly vibrated and fall into the receiving box 20 inside the lower part of the box body 1. A vibration mechanism is provided to add vibration during the concrete screening process, so that the impurities in the concrete raw materials can be quickly and effectively screened out, thereby ensuring the uniformity of the concrete raw materials.
[0027] When screening concrete, a large amount of dust will be generated. There are dust collecting hoods 8 on the left and right sides of the upper interior of the box body 1. There is a microfiber cloth 10 inside the dust collecting hood 8. There is a dust suction device 12 outside the dust collecting hood 8. Turn on the dust suction device 12. When the dust suction device 12 starts to start, the dust generated during the concrete screening vibration can be directly sucked into the dust collecting hood 8. The recycling is convenient, and the dust in the box body 1 can be quickly and effectively removed, which ensures the health of the staff. At the same time, the protective cover 11 covers the outside of the dust suction device 12 to protect the dust suction device 12 from being damaged by external factors. When the dust collecting hood 8 is taken out of the interior of the box body 1 for cleaning, the protective cover 9 can be rotated so that the dust collecting hood 8 and the protective cover 9 are engaged, and the protective cover 9 covers the inside of the dust collecting hood 8. In this way, when the dust collecting hood 8 is taken out, the dust in the dust collecting hood 8 will not be spilled out.
[0028] like Figure 1 , Figure 2 and Figure 4As shown in , after the screening is completed, the single-axis motor 18 is turned on, and the single-axis motor 18 can drive the first pulley 15 below to rotate. At the same time, the outside of the first pulley 15 is provided with a connecting belt 17, and the connecting belt 17 connects the first pulley 15 and the second pulley 16. The first pulley 15 and the second pulley 16 are on the left and right sides of the upper part of the box body 1, so the rotation of the first pulley 15 will also drive the second pulley 16 to rotate together. In addition, the lower part of the first pulley 15 and the second pulley 16 are connected to the support frame 13, so the rotation of the first pulley 15 and the second pulley 16 will drive the support frame 13 to rotate on the upper left and right sides of the box body 1, and a plurality of spray heads 14 are distributed in an array below the support frame 13, so the rotation of the support frame 13 can drive the spray head 14 to rotate and spray above the box body 1. When the equipment is used up, the spray head 14 can rinse the inside of the box body 1, and then open the electric heating wire 19 inside the box body 1 after rinsing to dry the inside of the box body 1, so as to extend the service life of the equipment.
