In the case of full loading of the material frame 210, it is necessary to prevent or slow down new used sand from entering the material frame 210, so as to avoid the used sand from continuously accumulating or even overflowing; for this purpose, the detecting device 243 may interact with the shakeout machine 100, for example, an output signal of the detecting device 243 is connected with a variable frequency motor controller of the vibration exciter 120, and when the detecting device 243 sends an alarm signal to indicate that the material in the material frame 210 is full, the control system transmits the signal to the motor controller of the vibration exciter 120, so that the vibration exciter 120 automatically reduces the frequency and the exciting force, thereby reducing the amount of the shakeout machine 100.

In another embodiment, the detecting device 243 is in signal interaction with the slag discharging driving part 242. For example, when the detection device 243 sends out an alarm signal, indicating that the material in the material frame 210 is full, the shakeout machine 100 does not shake out any more, or the amount of shake out is reduced; the vibrator 220 continues to drive the material frame 210 to vibrate for a period of time, so that the slag discharging driving piece 242 drives the slag discharging door 241 to be far away from the slag hole 203 or the slag discharging hole after the old sand in the material frame 210 is completely crushed, and the slag is discharged.

In other embodiments, the detection device 243 may also be used to monitor the level of the material in the material frame 210 in real time.

Wherein, the detecting device 243 can adopt a level gauge; alternatively, a proportional relation between the compression amount and the load of the spring is utilized, and a correlation switch, a proximity switch, a laser ranging element and the like are adopted.

The specific function and specific configuration of the detection device 243 are not limited in this application.

Optionally, a lining board 244 is arranged at the bottom of the material frame 210, and a groove or a small hole is arranged on the lining board 244; the sand can fall through the screen openings onto the liner 244.

The lining plates 244 can thicken the bottom of the material frame 210, so that the structural rigidity of the material frame 210 is improved, and the service life of the material frame 210 is prolonged. Meanwhile, when the material sand falls onto the lining plate 244, the material sand collides with the lining plate 244, and can be further crushed, so that the regeneration effect is facilitated. In addition, grooves or small holes are formed in the lining plate 244, in the process of high-frequency vibration of the material frame 210, the material sand falling on the lining plate 244 is vibrated and fed towards the sand outlet 202, and in the process of vibration feeding, the material sand is continuously rubbed with the grooves or the small holes, so that the effect of further crushing can be achieved. In addition, the material sand can be clamped in the grooves or the small holes, and the material sand clamped in the grooves or the small holes can be rubbed with other material sand, so that the material sand clamped in the grooves or the small holes can replace the bottom of the material frame 210 and the lining plate 244 to be used for contacting the material sand, and can be further crushed by rubbing with other material sand; the bottom of the frame 210 and the liner 244 can be used for a longer period of time due to less contact with the sand.

Optionally, the crusher 200 further includes a base 251 and an elastic member 252, and the material frame 210 is elastically disposed on the base 251 by the elastic member 252.

The elastic member 252 may be a spring, or a functional member with deformation and recovery properties made of a flexible material (such as rubber).

The base 251 is fixedly arranged on the station, one end of the elastic piece 252 is fixedly connected with the base 251, and the other end is fixedly connected with the material frame 210. Because the material frame 210 is elastically arranged, when the vibrator 220 drives the material frame 210 to vibrate, the elastic member 252 is stretched in the process that the material frame 210 is far away from the base 251, and the elastic member 252 is compressed in the process that the material frame 210 is close to the base 251, so that the restoring potential energy of the elastic member 252 is beneficial to the stability and the persistence of the vibration of the material frame 210.

Optionally, the material frame 210 includes: a receiving part 211, wherein the sand inlet 201 is arranged in the receiving part 211, and the crushing plate 230 is arranged in the receiving part 211; a discharge part 212, wherein the sand outlet 202 and the slag outlet 203 are arranged on the discharge part 212; a screening plate 213 arranged in the discharge part 212, the slag outlet 203 arranged on one side of the screening plate 213, and the sand outlet 202 arranged below the screening plate 213; wherein, the material receiving part 211 is provided with a sand outlet hole, the sand outlet hole is arranged below the crushing plate 230, and the material sand can enter the material discharging part 212 through the sand outlet hole and then be discharged through the sand outlet 202; the receiving portion 211 is further provided with a slag outlet, the slag outlet is arranged on one side of the crushing plate 230, and slag can enter the discharging portion 212 through the slag outlet and then be discharged through the slag outlet 203.

Referring specifically to fig. 3, in the illustrated embodiment, a material receiving portion 211 is at the right portion of the material frame 210, and a material discharging portion 212 is at the left portion; the top end of the receiving part 211 is provided with a sand inlet 201, and old sand enters the receiving part 211 through the sand inlet 201; the material frame 210 vibrates at high frequency, and used sand is crushed into sand and slag; the sand enters the lower part of the receiving part 211 through the crushing plate 230; the lower part of the receiving part 211 is provided with a sand outlet, and the material sand can move towards the sand outlet through vibration feeding and can enter the discharging part 212 through the sand outlet; the sand outlet 202 is arranged at the bottom of the discharge part 212, and after the material sand enters the discharge part 212, the material sand can be discharged out of the discharge frame 210 through the sand outlet 202 under the influence of self weight; because the grain size of the slag is large, the slag cannot pass through the crushing plate 230 and can only remain on the crushing plate 230; when the slag outlet is in an open state, the slag can move towards the slag outlet through vibration feeding and can enter the discharging part 212 through the slag outlet; the sieving plate 213 is arranged below the slag outlet hole, and the slag falls onto the sieving plate 213 after passing through the slag outlet hole, so that the slag can be crushed again by striking the sieving plate 213, and in the process, the particle diameter of part of the slag can be reduced to be not more than a preset value, so that the slag is converted into the sand; the screening plate 213 is provided with screening holes, and the material sand formed after secondary crushing can pass through the screening holes and then be discharged through the sand outlet 202; the slag, which still has a particle size greater than a preset value after the secondary crushing, is moved towards the slag outlet 203 by vibratory feeding and finally discharged through the slag outlet 203.

In order to prevent the used sand which is not completely crushed from passing through the slag hole in advance and entering the discharging part 212, the crusher 200 further comprises a slag discharging door 241 and a slag discharging driving member 242, wherein the slag discharging door 241 is used for blocking the slag hole, and the slag discharging driving member 242 is used for driving the slag discharging door 241 to be close to or far away from the slag hole. Specifically, in the normal crushing process, the slag discharging gate 241 blocks the slag discharging hole, so that the used sand remains in the material receiving portion 211 and is subjected to vibration crushing; when slag is required to be discharged, the slag discharging door 241 is far away from the slag discharging hole, and the slag enters the discharging part 212 through the slag discharging hole.

It should be added that the mesh openings in the screening plate 213 are identical to the mesh openings in the crushing plate 230 for screening sand having a particle size not greater than a predetermined value. Thus, the sand screened through the breaker plate 230 must be able to pass through the screen plate 213. Thus, in the case that the slag hole is higher than the sand hole, the screening plate 213 may be disposed between the slag hole and the sand hole, or may be disposed below the sand hole, and the material sand formed by two crushing may pass through the screening plate 213.

The specific configuration of the transmitter 2 is not limited in the present application as long as the sand in the buffer sand hopper 1 in the pit a can be transmitted upward to the stripping regeneration line.

In one embodiment, the transmitter 2 may use bucket lifting and/or vibration conveying to realize the transmission of the high-temperature sand.

In another embodiment, the transmitter 2 may employ a high temperature conveyor belt.

Alternatively, the transmitter 2 is a pneumatic transmitting tank.

Further, the tank 21 is communicated with an air inlet device, and when in conveying, compressed air is input into the tank 21 through the air inlet 23 to drive the sand in the tank 21 to move along the conveying pipeline 22 to the demoulding and regenerating line.

In general, the demolding and regenerating line is installed on the ground so as to facilitate installation, maintenance and extraction of regenerated molding sand; and the tank body 21 of the pneumatic transmitting tank is arranged in the pit A. For the purpose of transporting the sand, the transport pipe 22 is provided with a bend section 22a for connecting the tank 21 and an upstream section extending to the ground. Alternatively, the bend section 22a takes the form of a "ox horn", the smaller the diameter of the bend section 22a the farther from the tank 21; in this way, abrasion of the conveying pipe 22 by the high-temperature sand during pneumatic conveying can be reduced.

Optionally, the efficient shakeout department provided by the application comprises at least two pneumatic sending tanks, and any buffer sand hopper 1 is connected with the two pneumatic sending tanks.

When one pneumatic transmitting tank transmits sand to the demolding regeneration line, the other pneumatic transmitting tank can receive the sand from the cache sand hopper 1; further, after the sand in one pneumatic sending tank is completely sent, the other pneumatic sending tank can take over the sand to send the sand to the demolding regeneration line; the uninterrupted transmission of the sand is realized, and the conveying efficiency of the sand is improved.

To facilitate installation and maintenance of the crusher 200, a first step is provided between the ground and the platform B; in order to facilitate the installation and maintenance of the transmitter 2, the bottom of the platform B and the pit a are provided with second steps.

In order to facilitate cleaning of the slag bucket 3, a hole is formed in the ground right above the slag bucket 3, and an opening plate is arranged on the side of the hole; when the opening plate is far away from the opening, the opening is opened, and an operator can take out the slag barrel 3 through the opening and clear slag in the slag barrel 3; after the cleaning is completed, an operator puts the slag bucket 3 back to the mounting frame C, and closes the opening plate, so that the opening plate shields the opening, and the hidden danger of the opening being exposed outside can be avoided.
