Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand unloading, in particular to a sand making machine unloading hopper. Background Art

[0002] Quartz sand making refers to the process of crushing and shaping the quartz sand raw materials through specific mechanical equipment (such as sand making machine) to obtain sand products of the required particle size and shape. After the sand making machine crushes the quartz sand raw materials, it will discharge the crushed quartz sand through the discharge hopper.

[0003] However, after the crushed quartz sand passes through the discharge hopper, it will be mixed with large-sized, incompletely crushed quartz sand particles, resulting in large differences in the particle sizes of the quartz sand particles after discharge. At present, a screening device is generally added to the discharge hopper to screen out quartz sand particles that meet the required particle size. However, large-sized quartz sand particles are retained on the screening device and are not easy to clean, or the machine needs to be shut down for cleaning, resulting in low quartz sand unloading efficiency.

[0028] When in use, the upper end of the housing 1 of the utility model is connected to the discharge port of the sand making machine; in the initial state, the straight edge of the guide plate 5 contacts the upper end of the partition 3, and the left cavity is blocked by the guide plate 5; open the discharge door 8, start the motor 14, and the motor 14 drives the gear 13 to rotate clockwise (the clockwise rotation of the gear 13 is Figure 2The gear 13 meshes with the tooth 12 to drive the screen plate 2 to rotate counterclockwise, the motor 14 drives the gear 13 to rotate counterclockwise, the gear 13 meshes with the tooth 12 to drive the screen plate 2 to rotate clockwise, the motor 14 drives the gear 13 to reciprocate clockwise or counterclockwise, and then drives the screen plate 2 to reciprocate counterclockwise or clockwise; under the guidance of the guide plate 5, the crushed quartz sand enters the right cavity and falls on the upper right side of the screen plate 2. With the reciprocating motion of the screen plate 2, The quartz sand particles in the right cavity that are smaller than the diameter of the sieve holes on the sieve plate 2 can be vibrated and screened, and the quartz sand particles screened out through the sieve holes are discharged through the lower hopper 7, and the quartz sand particles larger than the diameter of the sieve holes are retained on the sieve plate 2. The amount of quartz sand particles retained in the right cavity is observed through the discharge door 6 on the right side. When the large-diameter quartz sand particles in the right cavity and on the sieve plate 2 are accumulated, the motor 21 is started, and the motor 21 drives the gear 20 to rotate clockwise or counterclockwise (the gear 20 rotates clockwise or counterclockwise for Figure 2 The top view angle), after the gear 20 meshes with the tooth 2 19 to drive the bearing cylinder 4 to rotate 180 degrees counterclockwise or clockwise, the motor 21 stops working, and the guide plate 5 rotates 180 degrees with the bearing cylinder 4, and the guide plate 5 blocks the upper end opening of the right cavity. The quartz sand discharged by the sand making machine enters the left cavity under the guidance of the guide plate 5 and is screened in the left cavity; at this time, the discharge door 6 on the right side of the shell 1 remains closed, so that the screen plate 2 continues to screen the quartz sand in the right cavity for a period of time. The reason is that during the rotation of the guide plate 5 with the bearing cylinder 4, a part of the quartz sand still falls into the right cavity. After the quartz sand in the right cavity is screened, the discharge door 6 on the right side of the shell 1 is opened, and the large-size quartz sand particles retained in the right cavity can be cleaned. Moreover, during the cleaning, the left part of the screen plate 2 is still screening the quartz sand particles in the left cavity. After the cleaning in the right cavity is completed, the discharge door 6 on the right side of the shell 1 is closed;

[0029] Repeat the above process to adjust the supporting cylinder 4. The guide plate 5 can guide the quartz sand to different cavities. When the left cavity screens the quartz sand, the large-particle quartz sand in the right cavity is cleaned. When the right cavity screens the quartz sand, the large-particle quartz sand in the left cavity is cleaned. The unloading efficiency of the quartz sand can be improved without stopping the machine.

[0030] The preferred implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the above-mentioned embodiments. Without violating the spirit of the present invention, i.e., the disclosure scope, any equivalent or equivalent deformation or replacement of the technical solution of the present invention shall fall within the protection scope of the present invention.
