Jaw crushers are widely used because they have a fixed jaw and a movable jaw and they form a rock cavity with a large upper opening and a smaller lower opening. The existing jaw crusher has only one movable jaw, and the In , the damaged rock can only move downwards, but not upwards, so that the impact force in the same situation has a short stroke due to the falling of the rock, thereby significantly reducing the impact force effect

Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] Such as figure 1 As shown, a rock breaking machine with extended stroke impact force of the present invention includes a U-shaped frame 10 with the opening facing upwards, and a fixed jaw plate 11 installed on the upper left side of the U-shaped frame 10 using a horizontal column 12. The horizontal plate 13 installed on the upper right side of the U-shaped frame 10 rotates the composite movable jaw plate installed on the horizontal plate 13, and is installed on the side plates on both sides of the U-shaped frame 10 front and rear.
[0020] The fixed jaw plate 11, the compound movable jaw plate, and two side plates form the rock cavity 7 for accommodating the large rock 70 to be crushed. There is a certain gap between the composite movable jaw plate and the side plates on the front and rear sides, which is far less than the len...

The invention discloses a rock crushing machine with extended stroke impact force, which belongs to the technical field of rock crushing. It includes a U-shaped frame, a fixed jaw plate installed on the upper left side of the U-shaped frame by a horizontal column, a horizontal plate installed on the upper right side of the U-shaped frame, and a compound movable jaw installed on the horizontal plate. The plate is installed on the side plates on the front and rear sides of the U-shaped frame; the fixed jaw plate, the composite movable jaw plate, and the two side plates form a rock cavity that accommodates the large rock to be crushed; the inner middle and lower part of the fixed jaw plate is slidingly installed There is an expanding stroke plate, the composite movable jaw plate includes movable jaw plate A and movable jaw plate B, and the driving wheel, driven wheel A and driven wheel B are rotated on the horizontal plate, and the driving wheel is connected with driven wheel A and driven wheel B Engagement transmission. The invention is a rock breaker with simple and reasonable structure, double-moving jaws swing synchronously and in the same direction, built-in rocks can passively move upwards, and has impact force of extended stroke.
Description
technical field [0001] The invention mainly relates to the technical field of rock crushing, in particular to a rock crushing machine with extended stroke impact force. Background technique [0002] The rock crusher can break large rocks of uneven size after mining to form small rocks of almost the same size, which is convenient for transportation, loading and unloading, and engineering paving. Jaw crushers are widely used because they have a fixed jaw and a movable jaw and they form a rock cavity with a large upper opening and a smaller lower opening. The existing jaw crusher has only one movable jaw, and the Among them, the damaged rock can only move downwards, but not upwards, so that the impact force in the same situation will have a short stroke due to the falling of the rock, thereby significantly reducing the impact force effect. Therefore, it is of certain application value to design a rock crusher with extended stroke impact force. Contents of the invention [0...
