Description

[0002] In the production of refractory materials, raw material processing is a crucial link, and crushing, as a key step in raw material processing, directly affects the subsequent production quality and efficiency. Jaw crushers, as a commonly used crushing equipment, have been widely used in the field of refractory raw material processing due to their simple structure, reliable operation, and easy maintenance.

[0003] Although the existing jaw crusher has many advantages, its fixed jaw plate mechanism structure is relatively simple. When crushing materials, it can only achieve material crushing through the reciprocating movement of the movable jaw plate mechanism. There is a lack of corresponding impact crushing mechanism in the middle position of the crushing chamber to assist in the crushing of materials, so the crushing efficiency is low. Therefore, we proposed a jaw crushing equipment for refractory raw material processing to solve the above problems. Summary of the Invention

[0029] Embodiment 1:

[0030] Please refer to Figures 1-6 A kind of jaw crusher equipment for refractory raw material processing, including jaw fixing mechanism 1, jaw fixing mechanism 1 includes jaw fixing body 2, piston box 3 and piston box cover plate 4, jaw fixing body 2, piston box 3 and piston box cover plate 4 are fixedly installed by bolt, piston box 3 and piston box cover plate 4 are opened with crank installation chamber 401, the inside of piston box 3 between jaw fixing body 2 and piston box 3 is opened with several piston stroke channels 301, and piston stroke channel 301 one end is connected with the inside of crank installation chamber 401, piston stroke channel 301 other end extends to the installation contact surface of jaw fixing body 2;

[0031] An upper crankshaft 5 and a lower crankshaft 6 of the same structure are arranged inside the crankshaft installation chamber 401. Both ends of the upper crankshaft 5 and the lower crankshaft 6 are rotatably connected to the connection between the piston box 3 and the piston box cover plate 4 through bearings, and one end of the upper crankshaft 5 and the lower crankshaft 6 is fixedly installed with a gear 7, which is meshed with each other. A pulley 8 is fixedly installed on the other end of the upper crankshaft 5;

[0032] The upper crankshaft 5 and the lower crankshaft 6 are both rotatably connected to a plurality of reinforcing pistons 10 through connecting rods 9. The reinforcing pistons 10 are slidably connected inside the piston stroke channels 301 at the corresponding positions. The fixed jaw plate body 2 at the positions of the corresponding piston stroke channels 301 is provided with impact members 11. The impact members 11 include three impact rods 1101. The three impact rods 1101 are fixedly welded by connecting plate sections 1102. An impact pile section 1103 is also fixedly welded to one side of the connecting plate section 1102. The end of the impact pile section 1103 extends to the movable part at the corresponding position. Inside the plunger stroke channel 301, a longitudinal limiting groove 201 is provided inside the fixed jaw plate body 2 at a position corresponding to the connecting plate segment 1102 in the longitudinal direction. The connecting plate segment 1102 is slidably connected inside the longitudinal limiting groove 201 at the corresponding position. A plurality of through holes 202 are also provided on the fixed jaw plate body 2 at the position corresponding to the connecting plate segment 1102. The impact rod 1101 extends to the other side of the fixed jaw plate body 2 through the longitudinal limiting groove 201 and the through holes 202 at the corresponding position. A return spring 12 is sleeved on the impact rod 1101 located inside the longitudinal limiting groove 201.

[0033] The outer wall of the piston box 3 located on the fixed jaw plate mechanism 1 is fixedly installed with a jaw crusher casing 13 by bolts. The movable jaw mechanism 14 is rotatably connected to the jaw crusher casing 13 through a shaft seat, and the movable jaw plate body 1401, the main drive pulley 1402 and the driven pulley 1403 are fixedly installed on the movable jaw mechanism 14. A driving motor 15 is provided on one side of the jaw crusher casing 13. A pulley 2 1501 is fixedly installed on the end of the driving shaft on one side of the driving motor 15. The pulley 2 1501 is connected to the main drive pulley 1402 through a belt 16, and the main drive pulley 1402 is connected to the pulley 1 8 through a belt 2 17.

[0034] A crushing chamber is formed between the movable jaw plate body 1401 and the fixed jaw plate body 2 inside the jaw crusher housing 13 , and the bottom of the crushing chamber passes through the bottom of the jaw crusher housing 13 .

[0035] The working principle of this type of jaw crusher for refractory raw material processing is:

[0036] First, the drive motor 15 is started, and the main drive pulley 1402 and the pulley 18 are driven to rotate through the connection of the belt 16 and the belt 2 17. At this time, the movable jaw plate body 1401 of the movable jaw mechanism 14 can be driven to continuously perform a reciprocating extrusion action toward the side of the fixed jaw plate body 2, thereby facilitating the extrusion and crushing of the material (the specific structure of the movable jaw mechanism 14 and the principle of driving the movable jaw plate body 1401 are already known in the existing public technology and will not be described in detail here).

[0037] While the pulley 18 is rotating, the upper crankshaft 5 and the lower crankshaft 6 can be driven to rotate inside the crankshaft mounting chamber 401 at the same time through the connection of the two gears 7, and the plurality of reinforcing pistons 10 can be driven to reciprocate inside the corresponding piston stroke channel 301 through the connection of the connecting rod 9. When the reinforcing piston 10 moves toward the side of the fixed jaw plate body 2, it instantly contacts and collides with the impact pile section 1103 of the impact member 11, prompting the impact member 11 to instantly move toward the side of the movable jaw plate body 1401. At this time, the ends of the three impact rods 1101 on the impact member 11 can be instantly fed into the crushing chamber of the jaw crusher case 13 through the through-hole 202, and gradually protrude from the tooth surface of the longitudinal jaw teeth 203 until the reinforcing piston 10 moves to the final position, impacting the surface of the material staying at this position, imitating the principle of the impact drill, and accelerating the crushing efficiency of the material.

[0038] Then, as the upper crankshaft 5 and the lower crankshaft 6 continue to rotate, the reinforcing piston 10 is driven by the connection of the connecting rod 9 to move in the opposite direction to the fixed jaw plate body 2. At this time, the reinforcing piston 10 gradually breaks away from the contact with the impact pile section 1103 until it reaches the reset state. At the same time, the return spring 12 releases its rebound force, gradually pushing the impact member 11 in the opposite direction to the reset state, and making the side of the connecting plate section 1102 contact the end face of the piston stroke channel 301. At the same time, the impact rod 1101 gradually retracts and finally retracts and sinks into the tooth surface of the longitudinal jaw teeth 203, providing a space for the material to slide downward between the fixed jaw plate body 2 and the movable jaw plate body 1401. This reciprocating process allows the fixed jaw plate body 2 and the movable jaw plate body 1401 to squeeze and crush the material while the impact rod 1101 of the impact member 11 can continuously and reciprocally impact the material, facilitating the rapid crushing of the material.

[0039] Example 2:

[0040] In view of the above embodiment 1, for further description, refer to Figure 4-Figure 6 The thickness of the connecting plate segment 1102 is greater than the depth of the longitudinal limiting groove 201, the length of the connecting plate segment 1102 is greater than the inner wall diameter of the piston stroke channel 301, and two adjacent connecting plate segments 1102 in the longitudinal direction do not contact each other. The length of the impact pile segment 1103 is less than the inner wall length of the piston stroke channel 301, and one end of the impact rod 1101 has a conical tip structure;

[0041] Through the structural design that the thickness of the connecting plate section 1102 is greater than the depth of the longitudinal limit groove 201, an avoidance space can be provided for the reciprocating movement of the connecting plate section 1102, and the longitudinal limit groove 201 can also limit the reciprocating movement of the connecting plate section 1102, thereby improving the stability of the reciprocating movement structure; through the structural design that the length of the connecting plate section 1102 is greater than the inner wall diameter of the piston stroke channel 301, the connecting plate section 1102 can be fitted on the end face of the piston stroke channel 301 after resetting, and the resetting distance of the connecting plate section 1102 is positioned to avoid the impact rod 1101 from being separated from the through hole 202 due to excessive resetting distance; one end of the impact rod 1101 has a conical tip structure, which can increase the pressure of the impact rod 1101 during impact and improve the crushing efficiency of the material.

[0042] A number of longitudinal jaw teeth 203 are equidistantly provided on the fixed jaw plate body 2, and a through hole 202 is provided between two adjacent longitudinal jaw teeth 203. Through this structural design, after the impact member 11 is reset, the impact rod 1101 will eventually retract and be recessed into the tooth surface of the longitudinal jaw tooth 203, providing an escape space for the material to slide downward between the fixed jaw plate body 2 and the movable jaw plate body 1401, thereby avoiding the phenomenon of material blockage at this position.

[0043] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
