However, although the pushing element can increase the distance between the two movable jaws, the stone with larger particle size It enters between the two movable jaws and is rolled, but relatively, when the distance is large, the purpose of rolling the rock into a small particle size sandstone cannot be achieved. In addition, whether it is Stones with large or small particle sizes will cause the two movable jaws to bear extreme lateral stress during crushing. The transmission shaft of the two movable jaws will suffer from the problem of transmission shaft deformation and loss when subjected to lateral stress for a long time. A complete shutdown is required for the replacement of the transmission shaft, and the cost of parts of the transmission shaft also indirectly increases the manufacturing cost of the stone crushing operation.

The frame body 10 is provided with a plurality of elastic elements 13, and each elastic element 13 is arranged along the longitudinal direction and is opposite to the corresponding sliding seat 121. The elastic element 13 abuts against the sliding seat 121 in the initial state. On the side, when a thrust is applied to the sliding seat 121 toward the elastic element 13, the sliding seat 121 will slide toward the elastic element 13, and the elastic element 13 is compressed by the sliding seat 121 to be compressed and released After the pushing force, the sliding seat 121 will slide in a direction away from the elastic element 13 by the resilience of the elastic element 13. In addition, the elastic element 13 can be used with an adjusting device 14, and the user can follow the actual situation. According to the demand, the adjustment device 14 is rotated to change the resilience of the elastic element 13.

The frame body 10 is provided with a first motor 15, a second motor 16, and a reduction motor 17. The first motor 15 is arranged on the right side of the frame body 10; the reduction motor 17 is arranged on the first motor 15 On one side, the reduction motor 17 is used with the first motor 15; the second motor 16 is arranged above the first motor 15, and the first motor 15 and the second motor 16 can be used to provide a power.

The first roller 20 is transversely arranged on the frame body 10, the first roller 20 has a first transmission shaft 21, the first transmission shaft 21 passes through the first roller 20, and the first transmission Two ends of the shaft 21 are provided with a bearing 23, the bearing 23 is assembled with a bearing seat 11 provided on the frame body 10, and the first transmission shaft 21 is connected with the combination of the first motor 15 and the reduction motor 17 , The first motor 15 is activated to drive the first transmission shaft 21 and the first roller 20 to rotate. The outer peripheral surface of the first roller 20 is wavy-shaped. More specifically, the outer peripheral surface of the first roller 20 is composed of a plurality of grooves 201 and a plurality of ribs 202 alternately arranged with each other, and each groove 201 and each rib 202 are arranged along the radial direction.

The second roller 30 is arranged on the frame body 10, and the second roller 30 and the first roller 20 are arranged parallel to each other, and the first roller 20 and the second roller 30 are separated from each other. There is a crushing gap 35; the second roller 30 is mainly composed of a second transmission shaft 31, an inner bearing 32 and a counterweight 33. The middle section of the second transmission shaft 31 extends outward to form an eccentric convex In section 311, two ends of the eccentric convex section 311 are equipped with the inner bearing 32, the counterweight 33 and the second roller 30 are sleeved on the inner bearing 32 in sequence, so that the second transmission shaft 31 will not drive the counterweight 33 and the second roller 30 when rotating, which means that the counterweight 33 and the second roller 30 will not rotate synchronously with the second transmission shaft 31; the second transmission The two ends of the shaft 31 are provided with the bearings 23, and each of the bearings 23 is assembled with the corresponding sliding seat 121 on the frame body 10, so that the second roller 30 can slide linearly with respect to the first roller 20 The outer peripheral surface of the second roller 30 is wavy, which is composed of a plurality of grooves 301 and a plurality of ribs 302 arranged alternately in the radial direction.

Please refer to Figs. 5 and 6, it is particularly noted that, by the eccentric convex section 311 of the second transmission shaft 31, the second roller 30 can rotate eccentrically relative to the second transmission shaft 31 Rotation, more specifically, defines the central axis of the eccentric convex section 311 as L, the central axis of the second transmission shaft 31 is T, and the axis position of the eccentric convex section 311 deviates from the axis of the second transmission shaft 31 Position, the second roller 30 installed on the eccentric convex section 311 rotates around the axis of the eccentric convex section 311, as shown in Figure 5, when the central axis L of the eccentric convex section 311 rotates to the second When the drive shaft 31 is to the left of the central axis T, the grinding gap 35 formed between the first roller 20 and the second roller 30 is relatively small, as shown in Figure 6, when the eccentric convex section When the central axis L of 311 rotates to the right of the central axis T of the second transmission shaft 31, the grinding gap 35 formed between the first roller 20 and the second roller 30 is relatively large, and the second roller 30 Relative to the eccentric rotation of the second transmission shaft 31, the size of the grinding gap 35 can be periodically changed.

Please refer to Figures 1 and 2 again. When the preferred embodiment provided by this creation is actually used, first, start the first motor 15 and the second motor 16, and the first motor 15 outputs power to drive the first motor 15 The roller 20 rotates, the second motor 16 outputs power so that the second roller 30 can rotate eccentrically with respect to the second transmission shaft 31, and then the stones to be crushed are transferred from the first roller 20 and the second roller Throw in the top of the wheel 30, the stone enters the crushing gap 35 between the first roller 20 and the second roller 30. After being hit by the two rollers, the stone with a larger particle size It becomes sand and gravel with a smaller particle size to achieve the purpose of crushing stones.

Please refer to Figures 7 and 8. It is worth noting that the eccentric rotation of the second roller 30 relative to the second transmission shaft 31 can cause the size of the grinding gap 35 to periodically change, so When the crushing gap 35 changes from a small (as shown in Figure 6) to a larger one (as shown in Figure 7), the stones with a large particle size can enter the crushing gap 35 for rolling. It can effectively solve the problem that the stones with large particle size cannot be brought into the crushing gap 35 by the two rollers, and the stones are idling rolling on the two rollers. It has the effect of being suitable for crushing various sizes of stones.

Moreover, the first roller 20 and the second roller 30 can crush rocks by rolling, and can also crush rocks by high-speed impact by eccentric rotation of the second roller 30. The crushing method combined with rolling and impact can not only effectively improve the overall crushing effect, but also shorten the operation time of the crushing process.

In addition, the wavy lines on the outer peripheral surface of the first roller 20 and the second roller 30, combined with the impact crushing method of the second roller 30, can enhance the crushing effect, more specifically, because rocks will fall on the In the grooves 201, 301, the convex grooves 202, 302 corresponding to the grooves 201, 301 can hit the stones more accurately, which helps to improve the efficiency of the stone crushing.

Please refer to Figure 9. Due to the high hardness of the stone, if the second roller 30 and the first roller 20 are both fixed on the machine body and immovable, in this case, the first roller When the two rollers 30 crush rocks at high speed, both the first transmission shaft 21 and the second transmission shaft 31 will bear huge lateral stress, and by matching the displacement component 12 and the elastic element 13, When the second roller 30 hits a rock, each of the slide seats 121 loaded with the second roller 30 will slip on the corresponding slide rail 122 to release the first transmission shaft 21 and the second transmission shaft. The lateral stress borne by the transmission shaft 31 not only effectively solves the problem of deformation of the conventional transmission shaft due to long-term stress, but also greatly improves the durability of the first transmission shaft 21 and the second transmission shaft 31 .

The user can further rotate the adjusting device 14 of the elastic element 13 according to actual usage requirements, thereby changing the compressibility and resilience of the elastic element 13.

Please refer to Figure 10, the second motor 16 is driven by a belt 161 to drive the second drive shaft 31, and the second motor 16 is vertically arranged above the second roller 30, the reason for this arrangement is that When the second roller 30 is crushing rocks, in order to reduce the lateral stress borne by the second transmission shaft 31, each of the sliding seats 121 will slide in the direction of the elastic element 13 to release the lateral stress. The second motor 16 is arranged on the right side of the second roller 30 instead of above, the belt 161 is in a tensioned state in the initial state, and when the sliding seat 121 compresses the elastic element 13, the belt 161 will be The tension becomes non-tight. After the elastic element 13 rebounds, the belt 161 changes from slack to taut. When the belt 161 is alternately tensioned and loosened for a long time, cracks and breakage of the belt 161 are likely to occur. The second motor 16 is changed to be vertically arranged above the second roller 30, and the tension of the belt 161 can be maintained when the second roller 30 rotates to the left or right. Reduce the possibility of the belt 161 breaking due to alternating tension.

In addition, the counterweight 33 installed between the second transmission shaft 31 and the second roller 30 can increase the overall weight of the second roller 30 so that the second roller 30 faces the first roller. Wheel 20 turns eccentrically At this time, the strength of the second roller 30 hitting the rocks can be effectively improved, thereby achieving the purpose of enhancing the overall crushing effect.

The first motor 15 is used in conjunction with the reduction motor 17, so that the rotation speed of the first transmission shaft 21 is lower than the rotation speed of the second transmission shaft 31, and the slow rotation of the first roller 20 can crush the stone to be crushed. Blocks are gradually brought into the crushing gap 35 to prevent too many stones from entering the crushing gap 35 within a certain period of time, and then the problem of too late for crushing occurs. The high-speed rotation of the second drive shaft 31 can make the second roller 30 quickly hits the rock, and the first roller 20 and the second roller 30 are matched with different rotation speeds to achieve the purpose of optimizing the crushing effect.

However, the disclosure of the above embodiments is only used to illustrate the creation, not to limit the creation, so any changes in values or replacement of equivalent components should still belong to the scope of the creation.

To sum up, when people who are familiar with this art know that this creation can indeed achieve the aforementioned purpose, and that it has actually complied with the provisions of the Patent Law, they should apply in accordance with the law.
