Description

Technical Field

[0001] This utility model belongs to the technical field of grading devices, specifically relating to a grading device for manufactured sand production. Background Technology

[0002] Manufactured sand refers to sand processed by sand making machines and other auxiliary equipment. The finished product is more regular and can be processed into sand of different shapes and sizes according to different process requirements, which can better meet daily needs. In construction, in order to make manufactured sand have a high degree of compaction, it is necessary to combine and match particles of different sizes in a certain proportion. This process is also called the gradation of manufactured sand.

[0003] In existing technologies, manufactured sand of various particle sizes is usually weighed manually before being placed into a mixer for mixing. This results in low mechanization, low efficiency, and high manual labor intensity. Therefore, we provide a grading device for manufactured sand production. Utility Model Content

Detailed Implementation

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-4 As shown, a gradation device for manufactured sand production according to this utility model includes an arc-shaped shell 1 with an opening on the front side. A rotating shaft 11 is rotatably mounted in the middle of the arc-shaped shell 1. A U-shaped mounting bracket 12 is fixed at the upper end of the rotating shaft 11. A processing tank 13 is installed in the opening of the U-shaped mounting bracket 12. A first motor 14 is installed at the bottom of the arc-shaped shell 1. The output shaft of the first motor 14 is connected to the rotating shaft 11.

[0024] The upper side of the arc-shaped shell 1 is provided with several evenly distributed batching boxes 2. The upper end of the batching box 2 is provided with a feed inlet 21, and the lower end of the batching box 2 is provided with a discharge outlet 22 that communicates with the interior of the arc-shaped shell 1. A rotating rod 23 is rotatably installed on one side of the middle part of the batching box 2. A baffle 24 is installed on the rotating rod 23. An installation groove is opened in the middle of the baffle 24. A weighing device 25 is installed in the installation groove. A second motor 26 is installed on the outside of the batching box 2. The output shaft of the second motor 26 is connected to the rotating rod 23.

[0025] The processing tank 13 is equipped with a stirring mechanism.

[0026] The stirring mechanism includes a stirring shaft 131 rotatably mounted inside the processing tank 13. The lower end of the stirring shaft 131 passes through the processing tank 13 and is connected to a first gear 132. An arc-shaped gear ring 133 that meshes with the first gear 132 is fixed on the side wall of the arc-shaped shell 1.

[0027] The weighing device 25 is used to weigh raw materials. Its basic principle is to convert gravity into an electrical signal through a sensor. This technology is a conventional technology in the existing technology.

[0028] In use, the baffle 24 is in a horizontal position, dividing the middle of the mixing box 2. Raw materials are added into the mixing box 2 through the feed port 21. The raw materials fall onto the weighing device 25 for weighing. When the weight reaches the specified vertical weight, the addition of raw materials into the mixing box 2 is stopped. After the multiple mixing boxes 2 are filled, the first motor 14 is started to drive the processing tank 13 located in the U-shaped mounting bracket 12 to rotate through the rotating shaft 11, so that it is located below the discharge port 22. The second motor 26 drives the rotating rod 23 to rotate, causing the baffle 24 to flip downward. The raw materials will fall downward through the discharge port 22 into the processing tank 13. The above operation is repeated in sequence to add the raw materials from multiple mixing boxes 2 into the processing tank 13.

[0029] Since the first gear 132 at the bottom of the processing tank 13 meshes with the arc-shaped gear ring 133, it is only necessary to start the first motor 14 to drive the processing tank 13 to rotate continuously. Under the meshing of the first gear 132 and the arc-shaped gear ring 133, the stirring shaft 131 inside the processing tank 13 will rotate, which will enable the raw materials inside the processing tank 13 to be mixed evenly.

[0030] This utility model has a baffle with a weighing device inside the batching box, which can accurately weigh the raw materials, ensure that each raw material is added in the set ratio, guarantee the quality of the manufactured sand gradation, and drive the processing tank to rotate during the revolution. The first gear meshes with the arc-shaped gear ring to drive the stirring shaft to rotate, so as to uniformly mix the raw materials and realize the combination and matching of different particle sizes in a certain proportion.

[0031] The side wall of the stirring shaft 131 is provided with several secondary stirring shafts 1311; the several secondary stirring shafts 1311 can increase the stirring area and improve the mixing efficiency of raw materials.

[0032] The processing tank 13 is rotatably installed in the opening of the U-shaped mounting bracket 1 via a rotating block. The U-shaped mounting bracket 1 has a strip groove 3. The rotating block extends into the strip groove 3 and is connected to the second gear 31. A rack 32 that meshes with the second gear 31 is slidably installed in the strip groove 3. An electric telescopic rod 33 is installed in the strip groove 3. The output shaft of the electric telescopic rod 33 is connected to the rack 32.

[0033] When unloading raw materials from the processing tank 13, simply rotate the processing tank 13 to the opening of the front arc-shaped shell 1. This position is not obstructed by the arc-shaped gear ring 133. By activating the electric telescopic rod 33, the rack 32 is displaced, causing the second gear 31 to rotate. This rotation causes the processing tank 13 to flip, with the upper opening of the processing tank 13 facing downwards, allowing the raw materials inside to be poured out. This achieves the unloading operation of raw materials. The structure is simple and easy to use.

[0034] A support frame 101 is installed at the bottom of the arc-shaped shell 1; the support frame 101 is used to provide stable support for the arc-shaped shell 1.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
