Description

Technical Field

[0001] The utility model belongs to the technical field of cylinder head casting, and more specifically, particularly relates to a shakeout device for cylinder head casting production. Background Art

[0002] The function of the cylinder head is to seal the cylinder, jointly form a combustion space with the piston, and bear the action of high-temperature and high-pressure combustion gas. When the cylinder head is formed, generally, the cylinder head is formed by sand casting, and then the molding sand on the formed cylinder head is removed.

[0003] When the existing shakeout device for cylinder head casting production is in use, relatively small sand blocks are screened out through a sieve mesh and slide to the sand discharge port, while relatively large molding sand blocks remain on the sieve mesh. At this time, manual intervention is required to remove the molding sand blocks to reduce their influence on the subsequent shakeout of the cylinder head. This process is rather laborious and time-consuming. Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a shakeout device for cylinder head casting production is provided, with the expectation of achieving a more practical value purpose. Summary of the Utility Model

Vibration motors are installed on the outer walls of both sides of the sieve box. A sieve mesh is fixedly connected to the inner wall of the sieve box. A sand outlet chamber is opened at the bottom side of the sieve box close to the sieve mesh. A sand discharge port is opened at the bottom end of the sand outlet chamber, and a conveying mechanism is arranged directly below the sand discharge port. One end of the sieve box is provided with a grinding box. Two crushing rollers are rotatably connected in the grinding box. A chute is opened on one side of the sieve box close to the grinding box, and a baffle is slidably connected in the chute.

[0006] As a preferred technical solution of the utility model, one end of each of the two crushing rollers is connected with a gear through a shaft, and the two gears are meshed with each other. A driving motor I is fixedly installed at one end of the grinding box, and the driving motor I is in transmission connection with any one of the gears.

[0007] As a preferred technical solution of the utility model, the crushing teeth of the two crushing rollers are arranged in a staggered manner. A discharge port is arranged at the bottom end of the crushing roller, and the discharge port is arranged directly above the conveying mechanism.

[0008] As a preferred technical solution of the present utility model, the conveying mechanism includes a base disposed inside the frame. Vertical partitions are installed on both sides of the base. A plurality of mounting rollers are rotatably installed between the two groups of partitions. A conveyor belt is installed on the outer sides of the plurality of mounting rollers. A driving motor two is installed on one side of the partition. The output shaft of the driving motor two is in transmission connection with a group of mounting rollers located on the outermost side.

[0009] As a preferred technical solution of the present utility model, both ends of the top of the baffle are connected with fixing blocks. The bottom ends of the fixing blocks are fixedly connected with hydraulic cylinders. The bottom ends of the hydraulic cylinders are fixedly connected with the sieve box.

[0010] As a preferred technical solution of the present utility model, the inclination angle of the sieve mesh is the same as that of the sieve box. Support bars are fixedly installed on the surface of the sieve mesh.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] With the inclined sieve box and sieve mesh of the present utility model, after vibrating and removing the sand and taking out the cylinder head, large sand blocks can be quickly conveyed to the grinding box. Through the crushing rollers arranged inside the grinding box, the large sand blocks can be quickly crushed and ground, so as to facilitate the quick treatment and recycling of the sand blocks, avoid the situation of large sand blocks blocking the sieve holes, and effectively reduce the participation of manual labor; by setting the baffle and sliding it in the chute on one side of the sieve box to block and open the outlet, it can prevent the cylinder head from sliding into the grinding box during the sand removal process; by setting the conveying mechanism, it is convenient to prevent too much sand from spilling onto the ground. The partition can provide a block for the movement of the sand, so that the sand can move out of the device actively through the conveyor belt, increasing the practicability.

A sieve mesh 5 is fixedly connected to the inner wall of the sieve box 3. A sand discharging chamber 6 is opened at the bottom side of the sieve box 3 close to the sieve mesh 5. A sand discharging port is opened at the bottom end of the sand discharging chamber 6, and a conveying mechanism 7 is arranged directly below the sand discharging port. One end of the sieve box 3 is provided with a grinding box 8. Two groups of crushing rollers 801 are rotatably connected in the grinding box 8. A chute is opened on one side of the sieve box 3 close to the grinding box 8, and a baffle 9 is slidably connected in the chute.

[0024] Wherein, one end of each of the two groups of crushing rollers 801 is connected with a gear 802 through a shaft, and the two groups of gears 802 are meshed with each other. A driving motor one 803 is fixedly installed at one end of the grinding box 8, and the driving motor one 803 is in transmission connection with any one of the gears 802, so that the crushing rollers 801 can rotate synchronously and in opposite directions under the action of the driving motor one 803 to crush larger sand and stones.

[0025] Wherein, the crushing teeth of the two groups of crushing rollers 801 are arranged in a staggered manner. A discharge port 804 is arranged at the bottom end of the crushing roller 801, and the discharge port 804 is arranged directly above the conveying mechanism 7.

[0026] Wherein, the conveying mechanism 7 includes a base 701 arranged in the frame 1. Partition plates 702 are vertically installed on both sides of the base 701. A plurality of mounting rollers 703 are rotatably installed between the two groups of partition plates 702. A conveyor belt 704 is installed on the outer sides of the plurality of mounting rollers 703. A driving motor two 705 is installed on one side of the partition plate 702, and the output shaft of the driving motor two 705 is in transmission connection with one of the outermost mounting rollers 703, so that the sand blocks can be actively moved out of the device through the conveyor belt 704, increasing the practicability.

[0027] Wherein, both ends of the top of the baffle 9 are connected with fixing blocks 10. The bottom ends of the fixing blocks 10 are fixedly connected with hydraulic cylinders 11, and the bottom ends of the hydraulic cylinders 11 are fixedly connected with the sieve box 3 to block and open the outlet and prevent the cylinder head from sliding into the grinding box 8.

[0029] Working principle of this embodiment: When using this sand falling device, place the cylinder head to be demolded on the screen 5, connect the device to the power supply and the control switch, and then start the vibration motor 4. At this time, the vibration motor 4 drives the vibrating screen box 3 to vibrate, so that the screen 5 vibrates, causing the sand blocks inside the cylinder head to fall. When the small sand blocks fall into the sand discharge chamber 6 at the bottom of the screen 5, they are discharged through the sand discharge port onto the conveyor belt 704. After the vibration ends, take out the cylinder head, open the baffle 9 on one side of the vibrating screen box 3 through the hydraulic cylinder 11, and start the vibration motor 4 again. The large sand blocks slide into the grinding box 8 through vibration. Inside the grinding box 8, the driving motor 1 803 rotates to drive the crushing roller 801 to crush the large sand blocks, reducing the volume of the large sand blocks, and finally discharging them onto the conveyor belt 704 through the discharge port 804. The conveyor belt 704 moves to one side for subsequent recycling and utilization.
