Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a geode crusher.

[Prior art and problems to be solved]

Typical examples of conventional Jyo Crushers are:
A device as shown in FIG. 1 is known. This is a fixed jaw 101 fixed to a frame 100.
and a swing jaw 103 whose upper part is attached to an eccentric rotating shaft 102, and a fixed jaw 10.
A fixed crushing plate 104 is attached to the swing jaw 103, and a swing crushing plate 105 is attached to the swing jyo 103. Further, the lower part of the swing jaw 103 is connected to a support rod 107 having a tockle plate 106 attached to the frame 100. Fixed crushing plate 10
4 and the swing crushing plate 105 has a crushing chamber 108
A material to be crushed, such as a rock, is supplied into this crushing chamber 108, and by rotation of the eccentric rotating shaft 102, a swing jyo 103 and a swing crushing plate 10 are formed.
By operating 5, the swing crushing plate 105
and a fixed crushing plate 104 to chew the object to be crushed.

In such a conventional example, a rubbing action acts on the object to be crushed in the crushing chamber 108, and the object to be crushed, such as rocks, is likely to break due to its lines, and generally Stones are often flat or rod-shaped, and when used as concrete aggregate, they have the disadvantage of lacking strength. Therefore, it has been uneconomical to further process rocks, etc. that have been treated with a geo crusher with a repulsion type crusher. That is, conventionally, a geo crusher and a cone crusher (or a repulsion type crusher, etc.) were used in combination to crush rocks, etc. in the order of large size → medium size → small size. for example,
Rocks with a diameter of about 150 mm are crushed by Jio Crushers for 80
Crush into pieces of about 5 mm, then use a cone crusher to 5 mm
It was crushed into pieces of about 30 mm.

In addition, in the single-toggle type Jyo crusher shown in FIG. 1, compression crushing is mainly performed in the upper part of the crushing chamber 108, while grinding and crushing is mainly performed in the lower part, so there is a disadvantage that wear is significant. It was hot.

Furthermore, when the material to be crushed increases in volume, the amount that can be input from the entrance of the crushing chamber 108 is relatively small.

Another conventional example is known from Japanese Patent Publication No. 36-2641. This is because the lower part of the crushing chamber is curved toward the fixed tooth plate side, and more specifically, the plate surface shape of the lower part of the tooth plate is changed to a curved surface with the center of curvature on the fixed side, that is, the lower half plate surface of the fixed tooth plate. The lower half plate surface of the movable tooth plate is formed into a convex curved shape corresponding to the lower half plate surface. However, in this conventional example as well, the movement of the movable tooth plate in the lower part of the crushing chamber is to move obliquely upward toward the fixed tooth plate, and the object to be crushed is lifted from the bottom to the top. Therefore, the crushing capacity depends on the diameter
It was capable of crushing rocks approximately 150mm in size into pieces only approximately 80mm in size. However, if the movable toothed plate is regarded as a hammer, the hammer is not swung down from the top to the bottom, but is lifted from the bottom to the top, and the rock is lifted up and hit against the fixed toothed plate above. This is because it will happen. In order to increase the crushing ability, the movable tooth plate corresponding to this hammer must be swung down in a substantially straight line from the top toward the fixed tooth plate located below.

The present invention was invented in view of the above circumstances, and it exhibits a much larger crushing capacity compared to the size and weight of the machine, prevents uneven wear of the crushing plate, and can crush relatively large rocks at once. The object of the present invention is to provide a geocrusher capable of crushing particles to the size of gravel.

[Means for solving problems]

In order to achieve the above object, the present invention comprises a fixed jyo fixed to a frame, a swing jyo whose upper part is attached to an eccentric rotating shaft, a fixed crushing plate attached to the fixed jyo, and a swing crushing chamber attached to the swing jyo.

At the same time, an impact crushing chamber 11 is formed continuously from the compression crushing chamber 10 between the impact tooth plate 7 and the receiving crushing plate 8. In these compression and impact crushing chambers 10 and 11, objects A to be crushed, such as rocks, are crushed.

Although the receiving tooth plate 8 is configured to be movable from side to side, it may be of a fixed type, or may be configured to be movable up and down, or even diagonally.

Further, the reference numeral 12 in FIG. 2 is a tockle plate, and the reference numeral 12' is a tension member for pulling the swing jaw 4 toward the right in the figure. This tockle plate 12 is attached to the back of the swing jyo 4, and has one end on the swing jyo 4 side high and the other end low, and is close to a straight line going diagonally downward from the top of the striking tooth plate 7 in the striking crushing chamber 11. This is a motion in which the shaft receives an elliptical motion toward the toothed plate 8 and then turns downward.

In the one shown in FIG. 3, the entire surface shape of the swing crushing plate 6 and the impact tooth plate 7 is formed into a gently curved surface in the shape of an arc when viewed from the side, and the fixed crushing plate 5
The overall surface shape of the receiving tooth plate 8 is also formed into a gently curved surface in the form of an arc, and the impact crushing chamber 11 is formed continuously below the compression crushing chamber 10, as shown in FIG. It is similar to that.

The one shown in FIG. 4 also has a fixed crushing plate 5, a swing crushing plate 6, a percussion tooth plate 7, and a receiving tooth plate 8 with different shapes, and the basic structure is the same as that shown in FIG. be.

As explained above, the first invention includes a fixed jyo 2 fixed to a frame 1, a swing jyo 4 whose upper part is attached to an eccentric rotating shaft, a fixed crushing plate 5 attached to the fixed jyo 2, and a swing jyo 4. and a swing crushing plate 6 attached to the
A compression crushing chamber 10 is formed between the fixed crushing plate 5 and the swing crushing plate 6, and this compression crushing chamber 1
A striking crushing chamber 11 is formed between the following (a) and (b) which are connected to the lower side of the swing jey 4 and curved toward the swing jyo 4, (a) attached below the swing jyo 4,
(b) A striking tooth plate 7 provided at a position curved in one direction from the lower end of the swing crushing plate 6; A receiving tooth plate 8 is provided at a curved position, and one end of the swinging jaw 4 side of the tockle plate 12 attached to the back surface of the swinging jaw 4 is configured to be high and the other end is low, so that the impact toothing plate 7 in the impact crushing chamber 11 is This is a nearly linear elliptical motion diagonally downward from the top, which moves toward the tooth plate 8 and then turns downward.

Next, the second invention will be explained. This means that the receiving tooth plate 8 in each embodiment according to the first invention shown in FIGS. 2 to 4 is attached to the outer peripheral surface of a roller 14 rotatably attached to the frame 1 as shown in FIG. It has been changed. This roller 1
It is desirable that the rotating shaft 15 of No. 4 is also attached to the frame 1 so that its movement can be adjusted. Further, the fixed crushing plate 5,
The swing crushing plate 6 and the impact tooth plate 7 may have a trapezoidal shape in which the lower side is longer than the upper side as shown in FIG. 6, or may be fixed as shown in FIG. The crushing plate 5 and the swing crushing plate 6 may be formed into a rectangular shape, and the impact tooth plate 7 following the swing crushing plate 6 may be formed into a trapezoidal shape. This also applies to the first invention. That is,
Of course, it is also possible to use the shapes shown in FIGS. 6 and 7 in the first invention. In addition, in the first invention, the receiving tooth plate 8 can also be formed into a trapezoidal shape.

This second invention differs in structure from the first invention in that the impact crushing chamber 11 is formed between the following (a) and (b). (stomach)
A striking tooth plate 7 is attached below the swing jaw 4 and is provided at a position curved in one direction from the lower end of the swing crushing plate 6; Crushing plate 5 fixed at the receiving position
A rotatable roller 14 provided such that its center of rotation is approximately located on an extension line of the rotatable roller 14.

Next, the operations of the first and second inventions will be explained. First, the V-belt wheel 13 shown in FIG.
By rotating the swing jaw 4 attached to the eccentric rotating shaft 3, the swing jaw 4 is moved. The upper part of the swing jaw 4 makes the maximum circular motion, and as it approaches the lower part, it makes an elongated elliptical motion. Therefore, the material to be crushed A in the compression crushing chamber 10 is subjected to a compressive force by the fixed crushing plate 5 and the swing crushing plate 6, and is subjected to a coarse crushing process. The crushed material A that has been subjected to the coarse crushing process is moved into the impact crushing chamber 11 . The lower end of the swing jaw 4 acts as if hitting the receiving tooth plate 8 diagonally downward from above, so that the material A to be crushed in the impact crushing chamber 11 is processed into fine particles here. In the case of the second invention, the roller 14 is intermittently rotated in the direction of the arrow by the action of the impact tooth plate 7 attached to the lower end of the swing jaw 4.

Fixed crushing plate 5 in the first and second inventions
The surface shape of the swing crushing plate 6 is usually formed into a horizontal wave shape having uneven ridge lines in the horizontal direction, but various shapes of the wave shape are also conceivable.
For example, it is possible to provide a deformed surface having a series of height differences in the vertical direction of the crushing plates 5 and 6 to reduce the amount of rock sliding and improve the crushing performance.

Next, an embodiment of the third invention will be described with reference to the drawings from FIG. 8 onwards. This third invention also includes a fixed jaw 2 fixed to a frame 1 and a swing jaw 4 whose upper portion is attached to an eccentric rotating shaft 3.
and a fixed crushing plate 5 attached to the fixed jaw 2.
and a swing crushing plate 6 attached to the swing jyo 4. The object A to be crushed, such as rocks, is crushed between the fixed crush plate 5 and the swing crush plate 6. The point is that a striking tooth plate 7 is attached, and a receiving tooth plate 8 is attached to the frame 1 in opposition to this striking tooth plate 7.
This is similar to the first and second inventions described above.
In the third invention, two or more swing jyos 4 are attached to the eccentric rotating shaft 3, and the plurality of swing crushing plates 6 and impact tooth plates 7 attached to these two or more swing jyos 4 are made to swing at different times. It is composed of For example, the trapezoidal swing crushing plate 6 shown in FIG. 6 and the impact tooth plate 7 which is continuous thereto are vertically divided into two, and the swing crushing plate 6 and the impact tooth plate 7 are vertically moved alternately. (FIG. 8), and these striking tooth plates 7 act as if striking the receiving tooth plates 8 alternately (FIG. 9). In the embodiment shown in FIGS. 8 and 9, 2
Although the swing crushing plate 6 and the impact tooth plate 7 are attached to each of the two swing jaws 4, two or more of these may be provided. Further, the shape of the swing crushing plate 6 is not limited to a trapezoidal shape. In addition, the swing crushing plate 6 is divided into two or more parts, and a striking tooth plate 7 is provided at a position that is continuous with each swing crushing plate 6 and curved toward the swing jaw 4 side.
You can install them separately. It goes without saying that the fixed crushing plate 5, the swing crushing plate 6, the striking tooth plate 7, and the receiving tooth plate 8 having the side shapes shown in FIGS. 3 and 4 can also be used in this third invention.

The operation of the third invention is almost the same as the first invention, with the only difference being that since there are two or more swing jaws 4, these swing at different times. In the embodiment of the third aspect of the present invention having three or more swing jaws 4, there is no problem even if there are swing jaws 4 that operate synchronously, and it is sufficient that there are at least two groups of swing jaws 4 that operate in different ways.

A fourth invention uses a roller 14 instead of the receiving tooth plate 8 in the third invention.
That is, this fourth invention has a fixed jyo 2 fixed to a frame 1, a swing jyo 4 whose upper part is attached to an eccentric rotating shaft, a fixed crushing plate 5 attached to the fixed jyo 2, and a fixed crushing plate 5 attached to the swing jyo 4. A compression crushing chamber 10 is provided between the fixed crushing plate 5 and the swing crushing plate 6.
At the same time, an impact crushing chamber 11 is formed between (a) and (b) below the compression crushing chamber 10 and curved toward the swinging jaw 4 side, and (a) A percussion tooth plate 7 is attached below and provided at a position curved in one direction from the lower end of the swing crushing plate 6, and (b) a percussion tooth plate 7 is provided at a position where its outer peripheral curved surface receives the movement of the percussion tooth plate 7 as a substantially linear movement. and a rotatable roller 14 provided so that its center of rotation is approximately located on an extension line of the fixed crushing plate 5; two or more swing jey yos 4 mounted on eccentric rotating shafts, and each tockle plate 12 attached to the back surface of these swing jyo 4. One end of the swing jaw 4 side is configured to be high and the other end is configured to be low, and the impact crushing chamber 11
A near-straight elliptical motion diagonally downward from the top of the impact tooth plate 7 is a movement that turns downward after facing the roller 14, and a plurality of swing crushing plates 6 attached to these two or more swing jaws 4 and the impact The toothed plates 7 are configured to swing at different times.

〔effect〕

As explained above, according to the first to fourth inventions, after the rocks, etc. are roughly crushed between the fixed crushing plate and the swing crushing plate (that is, the compression crushing chamber), the rocks, etc. or the outer circumferential surface of the roller) and the impact tooth plate (i.e. impact crushing chamber), in other words, the "rubbing phenomenon" is first caused, and then the "squashing phenomenon" is caused by hitting from top to bottom with a hammer. ” By causing
Large rocks can be processed into fine grains at once without using a cone crusher or the like as secondary processing. In other words, it becomes possible to crush large rocks into gravel all at once. In addition, it skillfully utilizes the movement of the conventional swing jyo, and connects the field where the "crushing phenomenon" occurs to the lower part of the compression crushing chamber and curves toward the swing jyo side, in other words, the lower end of the swing jyo. Rocks, etc., are fine-grained between the receiving tooth plate set nearby and facing the lower end (or the roller and the impact tooth plate installed at or near the lower end, including the lower end), so the structure becomes complicated. Get older, get bigger,
Or it won't lead to an increase in costs. Furthermore, no special power is required other than the power to operate the swing jyo in order to cause the "squashing phenomenon", and moreover, the function of a cone crusher can be added to the conventional jio crusher simply by operating the swing jyo. It is extremely economical.

In addition, in the case where the receiving tooth plate is attached to the frame so that its movement can be adjusted, the gap between the receiving tooth plate and the striking tooth plate can be adjusted, which not only makes it possible to perform the desired fine grain treatment but also When the tooth plate becomes worn, it is only necessary to move it forward, and there is no need to replace the entire tooth plate as in the conventional case, which is economical.

In the second and fourth inventions, in which rollers are used in place of the toothed plate, the processed rocks, etc. are smoothly discharged by the rotation of the rollers, reducing the possibility of clogging at the outlet. Particularly, in the case where a plurality of striking tooth plates act to strike the roller alternately, the rotation of the roller becomes even easier. Furthermore, in cases where the overall shape of the fixed crushing plate and the swing crushing plate, the overall shape of the receiving tooth plate and the impact tooth plate, or both of the overall shapes are trapezoidal, the objects to be crushed (rocks, etc.) are crushed as they are crushed into smaller pieces. ) increases in volume, increasing the volume closer to the exit ensures smooth operation, improves evacuation, and reduces the power required to operate the swing jaw.

Furthermore, in the third and fourth inventions, in addition to the above-mentioned effects, the swing crushing plate and the impact tooth plate can be easily replaced, and better crushing can be expected.

What all of the present inventions have in common is that
The impact crushing chamber is curved toward the swing jaw side, and one end of the swinging jaw side of the tockle plate attached to the back of the swing jaw is configured to be high and the other end is configured to be low, and the impact tooth plate in the impact crushing chamber is curved diagonally downward from above. The combination of the nearly straight elliptical motion towards the tooth plate (or roller) and the downward turn motion significantly enhances the crushing ability in the impact crushing chamber. This point is the most distinctive feature that is not found in conventional geocrushers.
