Detailed Description
The invention will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:
the sand making machine impact lining plate shown in fig. 1 to 3 has the following specific implementation mode: the counterattack lining plate 1 is arranged on a counterattack frame of a sand making machine, the counterattack frame comprises a supporting plate 2 and a panel 3, the counterattack lining plate 1 is fixed on the supporting plate 2 through the panel 3, a plurality of counterattack lining plates 1 can be arranged on one counterattack frame, the counterattack surface of the counterattack lining plate 1 and an installation surface have an inclination angle, a counterattack part and a clearance area 7 are respectively arranged on the counterattack surface from top to bottom, the counterattack part comprises two teeth 8 which are sequentially arranged on the counterattack surface from bottom to top, the teeth at the uppermost end of the counterattack lining plate 1 are removed and changed into the clearance area 7, and then the two teeth 8 at the lower end have space, so that the counterattack lining plate 1 can be properly thickened, and the thickness of the counterattack lining plate 1 is thicker than the traditional thickness and is increased from 90mm to 110mm, thereby increasing the wear resistance and prolonging the service life of the counterattack lining plate 1; in addition, through the arrangement of the two teeth 2, on one hand, the impact area of the impact lining plate 1 is enlarged, on the other hand, the sand and stone materials vertically impact the impact lining plate 1, the sand and stone materials are enabled to splash at various angles, the times of mutual collision are increased, the sand and stone material impact device is more like a natural sand forming process, the crushing efficiency is improved, and the formed sand is good in shape and reasonable in particle size proportion.
Preferably, the inclination angle of the impact surface is 15-20 degrees, and experiments prove that if the impact surface and the mounting surface are designed in parallel, the impact angle on the impact lining plate 1 is less in change, and the total area of the impact surface is smaller, and when the impact surface is inclined, the impact angles at all positions on the impact lining plate 1 are different due to the relationship of the teeth 2, so that the material impact efficiency is greatly improved, and the total area of the impact surface is improved, so that the crushing efficiency is improved; and because the impact lining plate 1 needs to bear larger impact force, the impact lining plate is not suitable to be too thin, the inclination angle is correspondingly smaller, and the same technical effect can be achieved by adopting the inclination angle of 15-20 degrees.
Preferably, two countersunk head screw holes 41 are arranged on the impact lining plate 1, and the panel 3 and the impact lining plate 1 are locked and fixed through screws and nuts; a plurality of countersunk screw holes 41 are designed to ensure the stability of the mounting structure; correspondingly, 3 grooves 61 are uniformly formed in the mounting surface of the impact lining plate 1 and are arranged on two sides and in the middle of the two countersunk screw holes 41, the grooves 61 are designed to increase the contact pressure of the impact lining plate 1, increase the friction force and improve the mounting stability; if the mounting surface of the impact lining plate 1 is a plane, the screw rod needs very large torsion to lock the impact lining plate 1 and the panel 3, and after the groove 61 is arranged, the large torsion is not needed, so that the problem that the fatigue of the screw rod is reduced and the stability of the equipment is reduced is avoided; in this embodiment, the depth of the groove 61 is 3-7mm, and the depth can be properly adjusted according to the size of the device.
The utility model discloses in tooth 8 highly be 20-25mm, and tooth 8 narrowest width is 19-33mm, and such size design is more than traditional tooth and will be thick, improves wear resistance, and makes broken material granularity even, more looks like natural sand grain, and the system sand effect is better. If the upper bottom edge and the lower bottom edge of the sawtooth are shorter, the sawtooth is easy to crush and wear, and if the sawtooth is longer, the sawtooth effect cannot be achieved, or the sawtooth crushing effect is not good, the height is the same, the sawtooth is easy to damage when the height is too high, and the material crushing effect is poor when the height is too low; in addition, the size can be properly adjusted according to the hardness of the material and the hardness of the raw material of the lining plate, and the same technical effect can be achieved.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above, and it should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only illustrative of the principles of the present invention, and the present invention can be modified in various ways without departing from the spirit and scope of the present invention, and these modifications and changes fall into the scope of the present invention as claimed.
