The existing crushing method is to hinge a pressure roller at the end of the sand mold chain plate conveyor belt through a bracket, and rely on the chain plate conveyor belt to push the pressure roller to rotate to generate pressure and the self-weight of the pressure roller to crush the sand mold. This crushing method has a small force, low crushing efficiency, and it is difficult to ensure that the sand mold is crushed into a sufficiently fine state. Content of the Utility Model

[0003] The purpose of the utility model is to provide a scale conveyor line with a sand mold crushing mechanism that has a simple structure and can effectively increase the force of the pressure roller in view of the above-mentioned deficiencies of the prior art.

[0004] The technical solution of the utility model is realized as follows: A scale conveyor line with a sand mold crushing mechanism includes a scale conveyor for conveying sand molds. A swing bracket is provided near the end of the output end of the scale conveyor. A pressure roller matching the end of the scale conveyor is provided on the swing bracket. Baffle bumps are provided on the surfaces of the chain plates of the scale conveyor. The pressure roller is connected to the output end of the scale conveyor through a transmission component, and the pressure roller rotates in the opposite direction to the scale conveyor. An adaptive elastic component matching the swing bracket is provided on one side of the scale conveyor.

[0005] In the above-mentioned scale conveyor line with a sand mold crushing mechanism, a number of columns of auxiliary pressure blocks are evenly distributed along the circumference of the pressure roller at intervals, and adjacent two columns of auxiliary pressure blocks are staggered.

[0006] In the above-mentioned scale conveyor line with a sand mold crushing mechanism, the auxiliary pressure block includes a hinge block provided on the outer wall of the pressure roller, and an arc-shaped pressure block is hinged on the hinge block. The inner side of the arc-shaped pressure block is adapted to the surface of the scale conveyor, and the outer side of the arc-shaped pressure block is conical. When the arc-shaped pressure block rotates to the lower end and contacts the surface of the scale conveyor or the sand mold, the arc-shaped pressure block closely adheres to the outer wall of the pressure roller. A limit stop block matching the hinge block is provided at one end of the arc-shaped pressure block in the rotation direction of the pressure roller.

[0007] In the above-mentioned scale conveyor line with a sand mold crushing mechanism, the adaptive elastic component includes a lifting bracket provided on one side of the scale conveyor. An installation suspension is provided on the lifting bracket, and a tension spring is connected between the installation suspension and the swing bracket.

[0008] In the above-mentioned apron conveyor line with a sand mold crushing mechanism, the transmission assembly includes the roller shaft of the end roller of the apron conveyor. A first driving wheel is provided at one end of the roller shaft; a first shaft seat cooperating with the roller shaft is provided on the apron conveyor frame. A direction-changing driving wheel is provided at the upper end of the first shaft seat through a second shaft seat. A second driving wheel is provided at one end of the roller shaft of the pressing roller; the first driving wheel, the direction-changing driving wheel and the second driving wheel are connected by a transmission belt.

[0009] After the present utility model adopts the above structure, the transmission assembly provides rotational power for the pressing roller. At the same time, when the pressing roller is lifted by the material blocking convex block and then falls back onto the apron conveyor, a thrust is applied to the pressing roller through the cooperation of the adaptive elastic component and the swing bracket, which can effectively improve the pressing force of the pressing roller on the sand mold on the apron conveyor, and effectively improve the crushing efficiency and crushing quality.

[0014] Refer to Figure 1-2As shown in the figure, a scale conveyor line with a sand mold crushing mechanism of the present utility model includes a scale conveyor 1 for conveying sand molds. Near the end of the output end of the scale conveyor 1, there is a swing bracket 2. A pressure roller 3 matching the end of the scale conveyor 1 is arranged on the swing bracket 2. On the surface of each chain plate of the scale conveyor 1, there are material retaining bumps 4. The pressure roller 3 is connected to the output end of the scale conveyor 1 through a transmission assembly 5. The rotation direction of the pressure roller 3 is opposite to that of the scale conveyor 1. On one side of the scale conveyor 1, there is an adaptive elastic assembly 6 matching the swing bracket 2. By the transmission assembly, rotational power is provided for the pressure roller. At the same time, when the pressure roller is lifted by the material retaining bump and then falls back onto the scale conveyor, a thrust is applied to the pressure roller through the cooperation of the adaptive elastic assembly and the swing bracket, which can effectively improve the rolling pressure of the pressure roller on the sand molds on the scale conveyor, and effectively improve the crushing efficiency and quality.

[0015] The swing bracket includes a fixed bracket arranged on the frame of the scale conveyor. A swing suspension is hinged on the fixed bracket. The pressure roller is installed at the near end of the free end of the swing suspension through a shaft seat.

[0016] In this embodiment, preferably, several columns of auxiliary pressing blocks 7 are evenly distributed along the circumferential direction of the pressure roller 3 at intervals, and adjacent two columns of auxiliary pressing blocks 7 are staggered. By arranging the auxiliary pressing blocks to roll the sand molds, the pressure on the contact surface between the pressure roller and the sand molds is increased, enabling it to better crush the sand molds. At the same time, the staggered auxiliary pressing blocks can roll when sand molds of different sizes pass through the auxiliary pressing blocks simultaneously.

[0017] Further preferably, the auxiliary pressing block 7 includes a hinged block 7a arranged on the outer wall of the pressure roller 3. An arc-shaped pressing block 7b is hinged on the hinged block 7a. The inner side of the arc-shaped pressing block 7b is adapted to the surface of the scale conveyor 1. The outer side of the arc-shaped pressing block 7b is conical. When the arc-shaped pressing block 7b rotates to the lower end and contacts the surface of the scale conveyor 1 or the sand mold, the arc-shaped pressing block 7b closely adheres to the outer wall of the pressure roller 3. At one end of the arc-shaped pressing block 7b in the rotation direction of the pressure roller 3, there is a limit stop block 7c matching the hinged block 7a. After adopting this structure, the hinge shafts of the arc-shaped pressing blocks and the hinged blocks can be taken out for individual disassembly, which is convenient for individual replacement when the arc-shaped pressing blocks are worn.

[0018] In this embodiment, preferably, the adaptive elastic assembly 6 includes a lifting bracket 6a arranged on one side of the scale conveyor 1. An installation suspension 6b is arranged on the lifting bracket 6a. A tension spring 6c is connected between the installation suspension 6b and the swing bracket 2. The installation height of the tension spring is adjusted through the lifting bracket. When different-sized pressure rollers are installed on the swing bracket, they can all closely adhere to the surface of the scale conveyor. And the thrust applied by the tension spring to the swing bracket can be adjusted, and the height that the pressure roller can be lifted can be adjusted, which can ensure the rolling of sand molds of different sizes.

[0019] The lifting bracket includes two lifting rods, on which sleeves are respectively sleeved, and the mounting suspension is connected between the two sleeves. A quick-lock positioning structure is provided between the lifting rod and the sleeve, which is the prior art and will not be elaborated here.

[0020] In this embodiment, the transmission assembly 5 includes the roller shaft 5a of the end roller of the scale conveyor 1. A first transmission wheel 5b is provided at one end of the roller shaft 5a; a first shaft seat 5c cooperating with the roller shaft 5a is provided on the frame of the scale conveyor 1. A direction-changing transmission wheel 5e is provided at the upper end of the first shaft seat 5c through a second shaft seat 5d. A second transmission wheel 5f is provided at one end of the roller shaft of the pressure roller 3; the first transmission wheel 5b, the direction-changing transmission wheel 5e and the second transmission wheel 5f are connected by a transmission belt 5g. The transmission belt crosses and changes direction at the direction-changing transmission wheel, so that the first transmission wheel and the second transmission wheel rotate in opposite directions. The specific structure is common knowledge to those skilled in the art and will not be elaborated here. In addition, a chain or gear transmission method can also be used.

[0021] During operation, when the scale conveyor is running, the end roller drives the pressure roller to rotate in the opposite direction through the transmission belt. The sand mold is placed on the scale conveyor and transported to the roller for rolling and crushing. After the roller is lifted by the sand mold or the material blocking projection, it hits down on the scale conveyor under the action of the tension spring and its own weight to crush the sand mold by hitting.

[0022] The above-described embodiments are the preferred embodiments of the present invention, which are only used to conveniently illustrate the present invention and do not impose any form of limitation on the present invention. Any person with ordinary knowledge in the technical field, without departing from the technical features of the present invention, makes an equivalent embodiment with partial modification or decoration using the technical content disclosed by the present invention, and without departing from the technical feature content of the present invention, still falls within the scope of the technical features of the present invention.
