When raw materials with different requirements need to be processed and the blanking grate 3 needs to be replaced, firstly, the upper shell is separated from the lower shell 1, and the rotating shaft and the hammer head are taken down from the lower shell 1; the fixing mechanism is loosened, then the intracavity lining plates 5 are rotated towards the middle part of the lower shell 1, the distance between the intracavity lining plates 5 and the supporting bars 2 is larger, the original blanking grates 3 can be conveniently taken out, and new blanking grates 3 are placed; after the placement is finished, the position of the inner cavity lining plate 5 is fixed through a fixing mechanism after the inner cavity lining plate 5 is rotated reversely; finally, the rotating shaft, the upper shell and the like are assembled on the lower shell 1 again, so that the replacement of the blanking grate 3 is completed.

Because when taking out and putting new unloading castor bean 3, the interval between support bar 2 and intracavity welt 5 is all great this moment, consequently just can make take out and put new more simple and convenient, the simple operation degree is higher, and the operation degree of difficulty is also littleer. Simultaneously because can change unloading grate 3 after getting up intracavity lining plate 5 rotation, consequently in the time of actual design, can also be appropriate set up the width of unloading grate 3 to the distance between support bar 2 and the intracavity lining plate 5 when being equal to just or being greater than first state slightly, so can also improve the positional stability of unloading grate 3, improve unloading quality.

When actually replacing the blanking grate 3, firstly, the nut 7 on the stabilizing rod 13 is removed, and then the stabilizing rod 13 is taken out from the stabilizing hole 12; then, the nut 7 on the positioning rod 8 is removed, the positioning rod 8 is knocked from the outside of the lower shell 1, the positioning part 5b is removed from the body part 5a, and the nut 7 on the hinge rod 6 is unscrewed; then, rotating the one side body portion 5a so that one of the holes is higher than the lower case 1, passing the stabilizer bar 13 through the hole, and then releasing the body portion 5a, at which time the body portion 5a is lapped on the top of the lower case 1 through the stabilizer bar 13;

a body part 5a of the reverse rotation side part, when the body part 5a is abutted against the body part 5a of the fixed position, it means that a hole is formed on the body part 5a just beyond the top of the lower housing 1 at this time, so that another stabilizer bar 13 can be passed through the hole, and thus the angles of the two body parts 5a on the same side are fixed; after the position of the body part 5a at the other side is adjusted in the same way, the blanking grate 3 can be conveniently replaced, and the operation is simple and convenient.

After all the blanking grates 3 are replaced, and the stabilizing bars 13 are pulled out, the part rotates downwards under the gravity and pushes against the blanking grates 3; afterwards go into the groove of stepping down 9 with location portion 5b card, two locating levers 8 have also passed two pairs of corresponding holes simultaneously, coupling nut 7 at last to tighten nut 7 on the hinge bar 6, realized the fixed of intracavity welt 5, it is simple and convenient.

Then, a proper stabilizer bar 13 is used, and after the stabilizer bar 13 passes through the stabilizing hole 12, a nut 7 is connected to the stabilizer bar 13; wherein the now replaced stabilization disk 14 can also come into contact with the grate bar support 4 at the top; although the top positions of the grate blocks 4 on different blanking grates 3 are fixed, the grate blocks 4 can be limited by replacing different stabilizing disks 14, so that the position stability of the blanking grates 3 is ensured.

In the actual use process, the two positioning rods 8 and the hinge rod 6 can fully ensure the position stability of the lining plate 5 in the cavity; meanwhile, in actual use, the positioning part 5b is clamped in the abdicating groove 9, so that the inner lining plate 5 can be prevented from occupying too much space in the lower shell 1, and the crushing of raw materials can be ensured to be normally carried out; meanwhile, the positioning part 5b is easy to deform or damage, so that the positioning part 5b only needs to be replaced regularly, and the main body part 5a has longer service life; and replacement of the positioning portion 5b is more simple and convenient.

The positioning grate 10 is selected to be used in the embodiment, and in practice, a plurality of positioning grates, such as 2-4 positioning grates, can be selected according to actual conditions; because the positioning grate 10 is positioned at the bottommost part, even if the positioning grate 10 is not limited by the cavity lining plates 5 (a certain distance is reserved between the two cavity lining plates 5) in the use process, the positioning grate 10 is fixedly connected in the lower shell 1, so that the position stability of all grates can be ensured; secondly, the positioning grate 10 has a limiting effect on the blanking grate 3, and the blanking grate 3 is prevented from moving to the space between the two cavity inner lining plates 5, so that the position stability of the blanking grate 3 is further improved and ensured. In the actual use process, the size of the positioning bulge 11 is slightly smaller than that of all the grate cushion blocks 4, so that overlarge materials can be prevented from falling out; meanwhile, although the positioning protrusions 11 can only drop smaller materials, the quality of the materials can be guaranteed.

Although the nuts 7 need to be removed and installed, the nut 7 is high in efficiency when an electric tool is used for installing and removing the nuts 7 in practice; secondly, although it takes a certain time to put and take the nut 7, the operation of replacing the blanking grate 3 is more trouble-saving and time-saving, and the difficulty of replacing the blanking grate is greatly reduced.

It should be noted that, in the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.

The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
