Description

Technical Field

[0001] The utility model belongs to the technical field of crushing devices, in particular to a foundry sand mold vibration crushing device. Background Art

[0002] Sand casting refers to a casting method that produces castings in sand molds. In the production industry of foundry sand, large block and granular materials need to be crushed and screened, and then fed to the conveying device evenly and continuously, and then the materials are sent to the receiving device through the conveying device. This process requires the use of crushers, screeners and conveyors.

[0003] When installing the equipment, the crusher, screener and conveyor need to be effectively connected. The simultaneous use of multiple devices will not only cause the equipment to occupy too much floor space, but also reduce the stability of the entire production process.

[0009] With the use of the limiting mechanism, the crushing trough can be stably and conveniently installed between the collecting trough, so that the crushed foundry sand can be conveniently collected and used.

[0010] As a preferred embodiment of the above technical solution, the inner wall of the side pull rod is provided with a protective pad that abuts against the docking block.

[0011] The protective pad can form a gap between the side pull rod and the docking block to prevent the two from directly contacting and causing collision.

[0026] A hydraulic rod 4 is installed at the bottom end of the side plate 3, and the hydraulic rod 4 is installed at the top of the mounting plate 6, wherein the mounting plate 6 is installed at the top of the docking block 16 through a limiting mechanism, and the docking block 16 is installed on the outside of the collecting tank 17. The side plate 3 and the mounting plate 6 are connected by a first elastic member 5, and the middle part of the first elastic member 5 surrounds the outer wall of the hydraulic rod 4; starting the hydraulic rod 4, the elastic potential energy of the first elastic member 5 can make the foundry sand that has been crushed inside the crushing tank 1 fall into the collecting tank 17 and be collected in accordance with the internal shape of the crushing tank 1 and the hole at the bottom of the crushing tank 1.

[0027] It should be noted that if Figure 1 As shown, in this embodiment, a spring is used as an elastic component to cooperate with the hydraulic rod 4 to adjust and move up and down, but in some other embodiments, other elastic components such as a reed, an elastic paddle, etc. can also be used.

[0028] like Figure 1, Figure 2 and Figure 3 As shown, the limiting mechanism includes a first limiting groove 7 provided on the side wall of the mounting plate 6, and the inner wall of the first limiting groove 7 is connected to a movable inner rod 9 through a second elastic member 8, the upper and lower ends of the inner wall of the movable inner rod 9 are fixedly connected to a first slider 10, and the first slider 10 slides in a first slide rail 11, and the first slide rail 11 is symmetrically provided in the first limiting groove 7, the outer side of the movable inner rod 9 is installed on a side pull rod 12, a limiting rod 13 is installed on the inner wall of the side pull rod 12 below the movable inner rod 9, and the inner side of the limiting rod 13 passes through the outer wall of the docking block 16 and is plugged into the plug-in block 14, the plug-in block 14 is installed at the bottom end of the mounting plate 6, and the bottom end of the plug-in block 14 is plugged into the top end of the docking block 16.

[0029] The elastic potential energy of the second elastic member 8 cooperates with the sliding action of the first slider 10 and the first slide rail 11 to pull the side pull rod 12 outward, drive the limit rod 13 to move outward to the maximum limit value, and then plug the plug-in block 14 into the docking block 16. After the plug-in is completed, the side pull rod 12 is released to complete the installation between the crushing tank 1 and the collecting tank 17.

[0030] like Figure 2 As shown, the inner wall of the side tie rod 12 is provided with a protective pad 15 that contacts the docking block 16; the protective pad 15 can form a gap between the side tie rod 12 and the docking block 16 to avoid direct contact and collision between the two, and the protective pad 15 can be made of other soft materials such as rubber.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, a connecting plate 18 is symmetrically installed at the bottom end of the crushing trough 1, and a plurality of second limit grooves 19 are equidistantly provided at the bottom end of the outer wall of the connecting plate 18, and the inner wall of the second limit groove 19 is connected to a mounting frame 21 through a third elastic member 20, and a ball 22 is rollingly embedded in the outer wall of the mounting frame 21, and the outer wall of the ball 22 rolls against the inner wall of the collecting trough 17, and a second slider 23 is fixedly installed at the upper and lower ends of the inner wall of the mounting frame 21, and the second slider 23 slides on the inner side of the second slide rail 24, and the second slide rail 24 is symmetrically provided in the second limit groove 19; it is worth noting that the bottom end height of the connecting plate 18 is shorter than the bottom end height of the plug-in block 14. Under the setting of the connecting plate 18, the plug-in block 14 can be conveniently inserted into the docking block 16, and at the same time, with the rolling effect of the ball 22, the sliding friction of direct contact between the connecting plate 18 and the inner wall of the collecting trough 17 is changed to rolling friction, thereby reducing the wear efficiency of friction.

[0032] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
