DETAILED DESCRIPTION
[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] Reference Figure 1-Figure 5 As shown, a cement mortar aggregate drying device comprises a bracket 1, a fine aggregate drying cylinder 6 and a coarse aggregate drying cylinder 7 are installed side by side on the top of the bracket 1, the fine aggregate drying cylinder 6 is used to dry large sand and gravel, and the coarse aggregate drying cylinder 7 is used to dry small sand and gravel. The fine aggregate drying cylinder 6 and the coarse aggregate drying cylinder 7 are both prior arts, and their specific structures and drying principles are not described in detail here. The bottoms of the fine aggregate drying cylinder 6 and the coarse aggregate drying cylinder 7 are both provided with discharge ports, and the volume of the coarse aggregate drying cylinder 7 is larger than the volume of the fine aggregate drying cylinder 6. A support rod 2 is installed on the back of the bracket 1, and a screening barrel 3 is installed on one side of the support rod 2. A screening mechanism 8 is arranged inside the screening barrel 3, and sand and gravel are fed into the support rod 2. The screening mechanism 8 can screen the sand and gravel according to their sizes, and the sand and gravel can be divided into large sand and gravel (coarse aggregate) and small Sand and gravel (fine aggregate), the outside of the screening barrel 3 is provided with a fine aggregate discharge port 4 and a coarse aggregate discharge port 5, a guide pipe 1 is installed between the fine aggregate discharge port 4 and the fine aggregate drying cylinder 6, and a guide pipe 2 is installed between the coarse aggregate discharge port 5 and the coarse aggregate drying cylinder 7. After the screening mechanism 8 classifies the sand and gravel, the small sand and gravel can fall into the guide pipe 1 from the fine aggregate discharge port 4, and enter the fine aggregate drying cylinder 6 along the guide pipe 1, and the small sand and gravel are dried separately through the fine aggregate drying cylinder 6, and the large sand and gravel can fall into the guide pipe 2 from the coarse aggregate discharge port 5, and enter the coarse aggregate drying cylinder 7 along the guide pipe 2, and the large sand and gravel are dried separately through the coarse aggregate drying cylinder 7. Drying the large sand and gravel separately from the small sand and gravel can not only improve the drying efficiency of the equipment for the aggregate, but also facilitate the staff to select and use the aggregate later, thereby improving work efficiency;
[0026] Specifically, the screening mechanism 8 includes a rotating shaft 81, and a plurality of screening plates 82 are slidably installed on the outside of the rotating shaft 81. The plurality of screening plates 82 are evenly distributed around the center of the rotating shaft 81. Two shifting plates 9 for shifting the screening plates 82 are installed on the inner walls on both sides of the screening barrel 3. The shifting plates 9 shift the screening plates 82 to cause the sand and gravel on the screening plates 82 to shake, thereby improving the screening efficiency of the screening plates 82.
[0027] More specifically, sliders 83 are installed at the front and rear ends of the screening plate 82. The slider 83 is set as an L-shaped block. An annular groove 84 is opened at the end of the rotating shaft 81 for the slider 83 to slide. A plurality of fixing plates 85 are installed inside the annular groove 84. The number of the fixing plates 85 is the same as that of the screening plate 82, and an arc spring 86 is installed between the fixing plate 85 and the slider 83. When the screening plate 82 is moved by the paddle plate 9, the sliding of the screening plate 82 drives the arc spring 86 to deform. When the screening plate 82 is separated from the paddle plate 9, the screening plate 82 can be reset by the elastic force of the arc spring 86 to achieve the vibration of the screening plate 82, so that the sand and gravel on the screening plate 82 can be fully screened.
[0028] Furthermore, the rotating shaft 81 is rotatably installed inside the screening barrel 3, and a motor 10 is installed on the side of the support rod 2 facing away from the screening barrel 3. The output end of the motor 10 is fixedly connected to the axis of the rotating shaft 81. The driving motor 10 can drive the rotating shaft 81 to rotate, and the rotation of the rotating shaft 81 can drive the screening plate 82 to rotate. When sand and gravel fall into the screening barrel 3, the sand and gravel can fall between the two screening plates 82. With the rotation and vibration of the screening plate 82, small sand and gravel can pass through the screening plate 82 and fall to the inner bottom wall of the screening barrel 3 and fall from the fine aggregate discharge port 4, while large sand and gravel continue to rotate with the screening plate 82 until the screening plate 82 rotates to the coarse aggregate discharge port 5. The large sand and gravel can slide out from the coarse aggregate discharge port 5 by its own gravity, thereby realizing the screening of large sand and gravel and small sand and gravel.
[0029] Furthermore, a beveled surface is provided on the side of the screening plate 82 away from the rotating shaft 81, and a plurality of inclined paddles adapted to the beveled surface are provided on one side of the paddle plate 9. The screening plate 82 can be rotated to abut against the plurality of inclined paddles one by one, and the arc spring 86 can be used to achieve repeated vibration of the screening plate 82. The vibration of the screening plate 82 drives the sand and gravel to vibrate, so that the sand and gravel can be fully screened.
[0030] Working principle: When in use, the fine aggregate drying cylinder 6, the coarse aggregate drying cylinder 7 and the motor 10 are driven, and the staff pours the sand and gravel into the screening barrel 3. The sand and gravel can fall between the two screening plates 82. The small sand and gravel can pass through the screening plate 82 and fall to the inner bottom wall of the screening barrel 3 and fall from the fine aggregate discharge port 4. The motor 10 drives the rotating shaft 81 to rotate, and the rotation of the rotating shaft 81 drives the screening plate 82 to rotate, and the large sand and gravel rotates with the screening plate 82 until the screening plate 82 rotates to the coarse aggregate discharge port 5. The large sand and gravel can slide out of the coarse aggregate discharge port 5 by its own gravity; during the rotation of the screening plate 82, when the screening plate 82 and the dial plate 9 are against each other, the large sand and gravel can slide out of the coarse aggregate discharge port 5 by its own gravity. , the arc spring 86 can drive the screening plate 82 to vibrate, and the sand and gravel on the screening plate 82 can be fully screened. The small sand and gravel falling from the fine aggregate discharge port 4 can enter the fine aggregate drying cylinder 6 along the guide pipe 1, and the small sand and gravel can be dried separately through the fine aggregate drying cylinder 6. The large sand and gravel falling from the coarse aggregate discharge port 5 can enter the coarse aggregate drying cylinder 7 along the guide pipe 2, and the large sand and gravel can be dried separately through the coarse aggregate drying cylinder 7. Drying the large sand and gravel separately from the small sand and gravel can not only improve the drying efficiency of the equipment for the aggregate, but also facilitate the staff to select and use the aggregate later, thereby improving work efficiency.
