[0002] With the increasing urbanization, the construction of buildings and their ancillary facilities is becoming more frequent. Stone is an essential raw material in construction projects. These projects often require large quantities of stone of varying sizes. Larger stones cannot be used directly and must be crushed before use. This necessitates crushing equipment. Currently, there are various types of stone crushing equipment, including jaw crushers, cone crushers, impact crushers, and hammer crushers. Jaw crushers typically consist of a stationary jaw and a moving jaw. Their operation involves the periodic reciprocating motion of the moving jaw to continuously compress the stone, thus crushing it. However, the moving jaw of current jaw crushers only moves up and down and back and forth, without any lateral movement, which is not conducive to crushing the stone into better-shaped particles. Utility Model Content

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0018] like Figure 1-6 As shown, this utility model provides a stone crushing device for stone production and processing, including a frame 1, a crushing box 2, a stationary jaw 3, a movable jaw plate 4, and a movable jaw mounting plate 5. The crushing box 2 is mounted on the frame 1, the stationary jaw 3 is vertically mounted on the inner wall of the crushing box 2, the movable jaw mounting plate 5 is mounted on the main drive mechanism installed in the crushing box 2, and the movable jaw plate 4 is laterally slidably mounted on the movable jaw mounting plate 5. The main drive mechanism causes the movable jaw mounting plate 5 and the movable jaw plate 4 to reciprocate up and down and back and forth. The side wall of the movable jaw plate 4 is connected to the auxiliary drive mechanism 6 mounted on the frame 1, which drives the movable jaw plate 4 to reciprocate laterally. In use, the main drive mechanism drives the moving jaw mounting plate 5 and the moving jaw plate 4 to reciprocate up and down and back and forth to crush the stone. The main drive mechanism is a conventional structure and technology of existing jaw crushers. The specific structure is not shown in the attached drawings, and its working principle is not described in detail. At the same time, the auxiliary drive mechanism 6 drives the moving jaw plate 4 to reciprocate laterally on the moving jaw mounting plate 5. Meanwhile, the main drive mechanism drives the moving jaw plate 4 and the moving jaw mounting plate 5 to reciprocate up and down and back and forth. This causes the moving jaw plate 4 to perform multiple-directional pressing, crushing, kneading and grinding actions on the stone, resulting in better particle shape of the crushed stone particles, more cubic stone particles and fewer needle-like and flaky particles, thus improving the quality of the crushed stone.

[0019] The auxiliary drive mechanism 6 includes a support frame 61, a drive rod 62, a drive sleeve 63, an eccentric shaft 64, a flywheel 65, and a motor 66. The support frame 61 is mounted on the frame 1 and located on the side wall of the crushing chamber 2. One end of the drive rod 62 passes through a through hole in the side wall of the crushing chamber 2 and is connected to the side wall of the moving jaw plate 4 via a universal joint 67. The other end of the drive rod 62 is connected to the side wall of the drive sleeve 63 via a universal joint 67. The drive sleeve 63 is rotatably mounted on the middle of the eccentric shaft 64 via bearings. The two ends of the eccentric shaft 64 are rotatably mounted on the two side walls of the support frame 61 via bearings. Two flywheels 65 are provided and are respectively mounted on the two ends of the eccentric shaft 64. The motor 66 is mounted on the frame 1 and is connected to one of the flywheels 65 via a belt drive. The lateral reciprocating movement of the movable jaw plate 4 is driven by the motor 66 to rotate the flywheel 65 and the eccentric shaft 64. The eccentric shaft 64 drives the drive sleeve 63 to reciprocate, thereby driving the drive rod 62 to pull the movable jaw plate 4 to slide laterally left and right on the movable jaw mounting plate 5. The two ends of the drive rod 62 are connected by universal joints 67, which can make the movable jaw plate 4 perform reciprocating movements up, down, forward, backward and left and right at the same time.

[0020] The upper and lower back ends of the movable jaw plate 4 are provided with buckle plates 41 that fasten into the slots 51 provided on the upper and lower parts of the mounting surface of the movable jaw mounting plate 5. The movable jaw plate 4 slides laterally left and right along the slots 51 via the buckle plates 41. Lubricant is provided in the slots 51.

[0021] Rollers 52 are evenly installed on the bottom and side walls of the slot 51, and the buckle plate 41 is slidably supported on the rollers 52; the rollers 52 are installed in the grooves 53 provided in the slot 51. Lubricant can also be added to the rollers 52 to make the moving jaw plate 4 move more smoothly.

[0022] A limiting plate 42 is provided on the side wall of the movable jaw plate 4 away from the drive rod 62. Multiple springs 7 are evenly connected between the limiting plate 42 and the side wall of the movable jaw mounting plate 5. When the drive rod 62 pulls the movable jaw plate 4 to slide laterally, the springs 7 are compressed. After the eccentric shaft 64 rotates one revolution, the springs 7 rebound, causing the movable jaw plate 4 to slide back. Under the push of the drive rod 62, the sliding is more effortless, making the lateral sliding of the movable jaw plate 4 smoother and less strenuous.

[0023] A protective plate 43 is provided at the lower end of the movable jaw plate 4. The protective plate 43 blocks the lower end of the movable jaw mounting plate 5. A roller 52 is installed at the lower end of the movable jaw mounting plate 5, which rolls in contact with the protective plate 43. The protective plate 43 can cause the movable jaw plate 4 to detach upwards.

[0024] Work process: In use, the main drive mechanism drives the moving jaw mounting plate 5 and the moving jaw plate 4 to reciprocate up and down and back and forth to crush the stone. At the same time, the auxiliary drive mechanism 6 drives the moving jaw plate 4 to reciprocate laterally on the moving jaw mounting plate 5. The main drive mechanism drives the moving jaw plate 4 and the moving jaw mounting plate 5 to reciprocate up and down and back and forth. The lateral reciprocating movement of the moving jaw plate 4 is driven by the motor 66 to rotate the flywheel 65 and the eccentric shaft 64. The eccentric shaft 64 drives the drive sleeve 63 to reciprocate, thereby driving the drive rod 62 to pull the moving jaw plate 4 to slide laterally on the moving jaw mounting plate 5. The two ends of the drive rod 62 are connected by universal joints 67, which can make the moving jaw plate 4 reciprocate up and down, back and forth and left and right at the same time. Thus, the moving jaw plate 4 performs multiple directions of pressing, crushing, kneading and grinding on the stone, so that the crushed stone particles have better shape, more cubic stone particles and fewer needle-like and flaky particles, thereby improving the quality of the crushed stone.
