[0004] The existing related technologies often have the following defects: when cleaning the manufactured sand, the cleaned manufactured sand will be conveyed into the collection box. The manufactured sand entering the collection box is likely to carry some moisture and is inconvenient to discharge, which easily causes bubbles and pores during the casting process when using the manufactured sand for casting, resulting in a rough surface of the casting and affecting the appearance quality of the casting.

[0005] Therefore, the utility model provides a manufactured sand cleaning device. Summary of the Utility Model

[0008] The effect achieved by the above components is that by setting the screening structure, it is convenient to discharge the water contained in the mechanism sand entering the collection box, thereby avoiding the water remaining in the mechanism sand and affecting the subsequent casting use, and further improving the cleaning effect of the mechanism sand.

[0009] Preferably, a plurality of cylinders are fixedly connected to the side of the rectangular plate close to the filter plate, and a round block is fixedly connected to the end of the cylinder close to the filter plate.

[0010] The effect achieved by the above components is that after the filter plate moves to a suitable position, it will hit the surface of the round block, and the round block reaches the function of restricting the moving distance of the filter plate towards the rectangular plate, thereby avoiding the spring being damaged due to the filter plate being too close to the rectangular plate.

[0013] Preferably, the cross-section of the filter plate is triangular.

[0014] The effect achieved by the above components is that when screening the mechanism sand, the mechanism sand falling on the surface of the filter plate can slide along the inclined surface, thereby avoiding the mechanism sand accumulating on one side of the filter plate and being inconvenient to screen out water.

[0015] Preferably, a limiting structure is provided on the surface of the collection box. The limiting structure includes two threaded rods, both of which are rotatably connected to the surface of the collection box.

Detailed implementation manners

[0032] Referring to Figure 1 shown, the present utility model provides a technical solution: a mechanism sand cleaning device, including a bottom plate 1, a support plate 2 is fixedly connected to the surface of the bottom plate 1, one end of the support plate 2 away from the bottom plate 1 is fixedly connected with a cleaning pipeline 3, one end of the cleaning pipeline 3 is communicated with a sand making machine 4, a water accumulation pool 5 is communicated with the surface of the cleaning pipeline 3, a collection box 6 is fixedly connected to the surface of the bottom plate 1, the collection box 6 is located below the end of the cleaning pipeline 3 away from the sand making machine 4, a water outlet pipe 7 is communicated with one side of the collection box 6, a screening structure 8 is arranged on the surface of the collection box 6. By setting the screening structure 8, it is convenient to discharge the water contained in the mechanism sand entering the collection box 6, thereby avoiding the water remaining in the mechanism sand and affecting the subsequent casting use, and further improving the cleaning effect of the mechanism sand. A limit structure 9 is arranged on the surface of the collection box 6. By setting the limit structure 9, the amplitude of the filter plate 807 can be limited, thereby avoiding the situation that the mechanism sand on the surface of the filter plate 807 is less and the mechanism sand splashes out of the collection box 6 due to too large amplitude.

[0033] The following specifically describes the specific settings and functions of its screening structure 8 and limit structure 9.

[0034] Referring to Figure 2 and Figure 3 andFigure 4 As shown, in this embodiment: The screening structure 8 includes a bracket 801, the bracket 801 is fixedly connected to one side of the collection box 6, the surface of the bracket 801 is fixedly connected with a servo motor 802, the output end of the servo motor 802 is fixedly connected with a driving rod 803, the end of the driving rod 803 away from the servo motor 802 is fixedly connected with a driving block 804, two rectangular plates 805 are fixedly connected to the inner wall of the collection box 6, several springs 806 are fixedly connected to the surface of the rectangular plates 805, and one end of several springs 806 away from the rectangular plates 805 is fixedly connected with a filter plate 807. Several cylinders 808 are fixedly connected to the side of the rectangular plate 805 close to the filter plate 807, a round block 809 is fixedly connected to the end of the cylinder 808 close to the filter plate 807, after the filter plate 807 moves to an appropriate position, it will hit the surface of the round block 809, and the round block 809 limits the distance of the filter plate 807 moving towards the rectangular plate 805, thus avoiding the situation that the filter plate 807 is too close to the rectangular plate 805 and causing damage to the springs 806. Two grooves 810 are formed on the surface of the driving block 804, a runner 811 is rotatably connected to the inner wall of the groove 810, after the driving block 804 rotates to an appropriate angle, it will drive the runner 811 to squeeze the filter plate 807, the runner 811 will rotate in the groove 810, and the runner 811 reduces the friction between the driving block 804 and the filter plate 807, thus facilitating the movement of the filter plate 807. The cross-section of the filter plate 807 is triangular, so when screening the manufactured sand, the manufactured sand falling on the surface of the filter plate 807 can slide along the inclined plane, thus avoiding the situation that the manufactured sand accumulates on one side of the filter plate 807 and is inconvenient to screen out the moisture.

[0035] Refer to Figure 2 and Figure 5As shown in the figure, specifically, the limiting structure 9 includes two threaded rods 91. Both of the two threaded rods 91 are rotatably connected to the surface of the collection box 6. A driving plate 92 is threadedly connected to the surface of the threaded rod 91. One end of the driving plate 92 close to the filter plate 807 is fixedly connected with a limiting block 93. Two guiding grooves 94 are formed in the inner wall of the collection box 6. A guiding rod 95 is slidably connected to the inner wall of the guiding groove 94. The guiding rod 95 is fixedly connected with the driving plate 92. When the driving plate 92 moves, it will drive the guiding rod 95 to slide along the inner wall of the guiding groove 94. The guiding groove 94 restricts the moving path of the guiding rod 95, thereby preventing the driving plate 92 from rotating when it moves. One side of the limiting block 93 close to the filter plate 807 is fixedly connected with a protective pad 96. The protective pad 96 is made of rubber. When the filter plate 807 moves upward, it will impact on the protective pad 96 on the surface of the limiting block 93. The protective pad 96 protects the impact area between the limiting block 93 and the filter plate 807, preventing the filter plate 807 and the limiting block 93 from being damaged. One end of the threaded rod 91 far from the collection box 6 is fixedly connected with a turntable 97. The cross-section of the turntable 97 is in the shape of a "plus" sign. When the turntable 97 rotates, it will drive the threaded rod 91 to rotate. The turntable 97 facilitates the rotation of the threaded rod 91.

[0036] Working principle: When the manufactured sand cleaned through the cleaning pipeline 3 enters the collection box 6, first drive the servo motor 802. The output end of the servo motor 802 will drive the driving rod 803 to rotate. When the driving rod 803 rotates, it will drive the driving block 804 to rotate. After the driving block 804 rotates to an appropriate angle, it will drive the runner 811 to squeeze the filter plate 807. The runner 811 will exert pressure on the filter plate 807 and slide along the surface of the filter plate 807. At this time, the runner 811 will rotate in the groove 810. The runner 811 reduces the friction between the driving block 804 and the filter plate 807, thereby facilitating the movement of the filter plate 807. When the filter plate 807 rotates, it will slide along the inner wall of the collection box 6 and stretch the spring 806. The spring 806 will be in a stretched state. When the angle of the driving block 804 rotates again, the driving block 804 will release the pressure on the filter plate 807. The filter plate 807 will move toward the direction close to the rectangular plate 805 by virtue of the contracting force of the spring 806. When the filter plate 807 moves to an appropriate position, it will impact on the surface of the round block 809. The round block 809 limits the distance of the filter plate 807 moving toward the rectangular plate 805, thereby preventing the spring 806 from being damaged due to the filter plate 807 being too close to the rectangular plate 805. Such repeated movements can make the filter plate 807 vibrate up and down repeatedly. At this time, the manufactured sand entering the collection box 6 will fall onto the surface of the filter plate 807. By means of vibration, the moisture in the manufactured sand can be shaken out. The moisture will fall from the filter holes on the surface of the filter plate 807 to the lower part of the filter plate 807, and then be discharged from the water outlet pipe 7.

[0037] When it is necessary to limit the amplitude of the filter plate 807, first rotate the turntable 97. The rotation of the turntable 97 will drive the rotation of the threaded rod 91. The rotation of the threaded rod 91 will drive the movement of the driving plate 92 by means of the thread. The movement of the driving plate 92 will drive the limiting block 93 to move towards the filter plate 807. The movement of the driving plate 92 will drive the guide rod 95 to slide along the inner wall of the guide groove 94. The guide groove 94 restricts the movement path of the guide rod 95, thus preventing the driving plate 92 from rotating during movement. When the limiting block 93 moves to an appropriate position, the filter plate 807 will hit the protective pad 96 on the surface of the limiting block 93 when moving upward. The limiting block 93 limits the amplitude of the filter plate 807, thus preventing less manufactured sand on the surface of the filter plate 807 and excessive amplitude from causing the manufactured sand to splash out of the collection box 6. The protective pad 96 protects the impact area between the limiting block 93 and the filter plate 807, preventing damage to the filter plate 807 and the limiting block 93.

For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.
