Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a sand box for placing sand molds, which comprises a box body 1, wherein two operating rods 11 are fixedly connected to two ends of the box body 1, as shown in fig. 1, 2 and 4. A fixing groove 12 is formed in one side of the box body 1, a containing groove 13 is formed in the upper end of the box body 1, the fixing groove 12 is communicated with the containing groove 13, and steel balls 2 and a sand mold 3 are arranged in the containing groove 13. The striker plate 4 is rotationally connected in the fixing groove 12, the round holes 14 are formed in two ends of the fixing groove 12, and the round shafts 41 embedded into the round holes 14 are fixedly connected to two ends of the striker plate 4. Two limiting parts 5 for limiting the rotation of the material baffle plate 4 are arranged on the box body 1. Fixing holes 15 communicated with the fixing grooves 12 are formed in two ends of the box body 1, and positioning grooves 42 corresponding to the two fixing holes 15 are formed in two ends of the material baffle plate 4. The limiting member 5 includes a positioning block 51 slidably disposed in the positioning groove 42 and a spring 52 disposed in the positioning groove 42, and two ends of the spring 52 are respectively abutted to the positioning block 51 and the bottom of the positioning groove 42. In a natural state, the positioning block 51 is fitted into the fixing hole 15.

As shown in fig. 3 and 5, the positioning groove 42 has first limiting grooves 43 formed at two ends thereof, the positioning block 51 is fixedly connected with two first limiting blocks 53 embedded in the two first limiting grooves 43, and the two positioning blocks 51 have chamfers 54 formed thereon. After 1 slope of box is poured steel ball 2 and sand mould 3, reset box 1 again and make box 1 level, the guard plate rotates downwards, chamfer 54 inclined plane and 1 butt of box make first stopper 53 slide along first spacing groove 43, spring 52 compression deformation simultaneously, make locating piece 51 imbed completely in the constant head tank 42, the guard plate further rotates, align with constant head tank 42 up to fixed orifices 15, spring 52 drive locating piece 51 is embedded into in fixed orifices 15, realize the fixed of guard plate and box 1.

As shown in fig. 2 and 3, the two ends of the fixing hole 15 are both provided with a second limiting groove 17, the fixing hole 15 is slidably provided with an operation block 16 abutted against the positioning block 51, and the operation block 16 is fixedly connected with two second limiting blocks 161 respectively embedded into the two second limiting grooves 17. The operation block 16 is driven to move the second stopper 161 along the second stopper groove 17, so that the operation block 16 abuts against the positioning block 51, and then the positioning block 51 is pushed to be separated from the fixing groove 12 and embedded into the positioning groove 42.

As shown in fig. 4 and 5, one end of the case 1, which is opened with the fixing groove 12, is opened with a screw hole 18 communicating with the fixing hole 15, and a bolt 19 abutting against the operation block 16 is screwed into the screw hole 18. Rotating the bolt 19 causes the bolt 19 to abut against the operation block 16, and fixing the operation block 16 makes the positioning block 51 not easily move, thereby preventing the guard plate from rotating. On the contrary, the bolt 19 is rotated to prevent the bolt 19 from abutting against the operation plate, the operation block 16 is driven to enable the positioning block 51 to be embedded into the positioning groove 42, and then the protection plate is rotated, so that the steel balls 2 in the accommodating groove 13 are separated from the sand mold 3.

As shown in fig. 1, a disc 111 is fixedly connected to the operating rod 11 away from the box 1, and the wire rope is wound around the operating rod 11, so that when the box 1 is lifted by the crane, the disc 111 can prevent the wire rope from moving along the axis of the operating rod 11 and separating from the operating rod 11, which may cause an accident.

As shown in figure 1, universal wheels 6 are fixedly connected to the bottom of the box body 1, and workers can drive the box body 1 to move at all required positions.

The working principle is as follows: when separating the steel balls 2, the sand molds 3 and the box body 1, firstly winding the steel wire rope on the operating rod 11, hoisting the box body 1 by using a crane to enable the box body 1 to incline and the protection plate to face downwards, then rotating the bolt 19 to enable the bolt 19 to be separated from the operating block 16, then applying pressure to the operating block 16 to enable the operating block 16 to push the positioning block 51 to move, enabling the positioning block 51 to be embedded into the positioning groove 42, and enabling the protection plate to be pushed to rotate by the gravity of the steel balls 2 and the sand molds 3 and to be separated from the accommodating groove 13.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
