Description

Technical Field

[0001] This invention relates to the field of aerated concrete block processing equipment, and more particularly to a jaw crusher for processing aerated concrete block raw materials. Background Technology

[0002] Aerated concrete blocks are lightweight, porous silicate building materials made primarily from siliceous materials (sand, fly ash, etc.) and calcareous materials (lime, cement), with the addition of aluminum powder as a foaming agent. The process involves batching, mixing, pouring, pre-curing, cutting, and autoclaving. The porosity reaches 70%-85%. Based on raw materials, they can be classified into fly ash aerated blocks, sand aerated blocks, etc. They possess lightweight, thermal insulation, sound insulation, and seismic resistance properties, and are widely used in non-load-bearing walls and prefabricated building panels. Their unit weight is one-third that of clay bricks, their thermal insulation performance is 3-4 times higher, and their sound insulation and impermeability performance are more than 2 times and 1 time higher, respectively.

[0003] In the production of aerated concrete blocks, raw materials must first be crushed to a specific particle size before entering the subsequent mixing and gasification processes. Jaw crushers, due to their simple structure and high crushing efficiency, are one of the core pieces of equipment in this stage. However, existing jaw crushers have the following problems in processing raw materials for aerated concrete blocks:

[0004] The feeding structure is prone to clogging, and the crushed raw material easily accumulates and blocks the feed plate, seriously affecting the continuity of production (for example, a jaw crusher disclosed in patent CN103394387A includes: a shell, a fixed jaw installed at the front end of the shell, a pair of lifting rings installed at the top of the shell, an eccentric shaft installed behind the lifting rings via a bearing, a flywheel installed on the eccentric shaft, a movable jaw installed in the middle of the eccentric shaft, a network camera installed on the fixed jaw, and a remote controller installed on the power equipment connected to the flywheel). Frequent manual cleaning is required. For example, during the crushing process, the crushed raw material is manually removed from the feed inlet to prevent blockage. However, manually removing the crushed raw material from the feed inlet poses safety hazards, is inefficient, and involves a large workload. If a pushing device is used to push away the blockage, additional power is required, and the pushing frequency needs to be controlled by electrical control equipment, increasing energy consumption.

[0005] Therefore, there is an urgent need for a jaw crusher that can clean and prevent clogging of crushed raw materials for processing aerated concrete blocks. Summary of the Invention

[0006] The purpose of this invention is to provide a jaw crusher for processing aerated concrete block raw materials, which solves the problem that the existing jaw crusher's material guiding structure is prone to clogging, and the crushed raw materials tend to accumulate and clog at the material guiding plate, affecting the continuity of production.

[0059] Compared with the prior art, the present invention has the following beneficial effects:

[0060] 1. The upper end of the gear lever of the anti-blocking pusher is connected to one end of the eccentric shaft. The pusher plate is set on the guide structure of the support base and connected to the pusher frame. The lower end of the gear lever is engaged with the movable pusher of the pusher frame. When cleaning the crushed raw material accumulated at the guide structure, one end of the eccentric shaft drives the upper end of the gear lever to move left and right, so that the gear structure at the lower end of the gear lever drives the movable pusher of the pusher frame to move left and right reciprocally, thereby driving the pusher plate to move left and right, pushing the crushed raw material accumulated at the guide structure and pushing the crushed raw material out of the guide structure. This effectively prevents the crushed raw material from accumulating at the guide structure and prevents blockage. No manual cleaning is required, improving efficiency and ensuring production continuity. At the same time, no additional pushing equipment or additional energy is required for driving.

[0061] 2. The adjusting seat connects one end of the elbow plate to the seat block and the other end to the lower end of the moving jaw plate. An adjusting shim is detachably inserted into the adjusting cavity of the seat block. Compared with the traditional jaw crusher adjustment method that requires disassembling the frame and stacking multiple layers of shims, the present invention can adjust the gap between the lower ends of the moving jaw plate and the fixed jaw plate simply by increasing or decreasing the number of adjusting shims in the adjusting cavity. The adjustment process does not require disassembling the core components, thus shortening the operation time and improving efficiency.

[0062] 3. The anti-blocking pusher unit is linked with the gear lever on the side of the flywheel, which directly converts the rotation of the eccentric shaft into the reciprocating power of the pusher plate. The pusher action is synchronized with the crushing action, that is, the pusher frequency is consistent with the swing frequency of the moving jaw plate. No additional motor or cylinder is required, and the energy consumption of the equipment is reduced. Attached Figure Description

[0083] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0084] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0085] Reference Figure 1-10 As shown, an embodiment of the present invention provides a jaw crusher for processing aerated concrete block raw materials, comprising:

[0086] Rack 100, rack 100 is used to provide a frame for mounting components;

[0087] The crushing jaw 200 includes an eccentric shaft 210 mounted on the upper end of the frame 100 and a movable jaw plate 220 mounted on the eccentric shaft 210. A fixed jaw plate 230 is installed at the front end of the inner side of the frame 100. A crushing chamber is formed between the movable jaw plate 220 and the fixed jaw plate 230. A side guard plate 110 is installed on the inner side wall of the crushing chamber of the frame 100. The surfaces of the movable jaw plate 220 and the fixed jaw plate 230 are both made of wear-resistant manganese steel and are provided with anti-slip teeth, forming a trapezoidal crushing chamber that is wider at the top and narrower at the bottom. After the raw material is fed into the feed port, it falls to the middle of the crushing chamber due to gravity, avoiding material splashing. The side guard plate 110 inside the crushing chamber of the frame 100 is made of wear-resistant manganese steel with a thickness of 15-20mm, which can directly withstand the impact and wear of the raw material and prevent the frame body from being eroded. The side guard plate 110 is removable and replaceable.

[0088] The adjusting seat 300 is installed at the rear end of the frame 100 and connected to the lower end of the movable jaw plate 220, and is used to adjust the gap between the lower end of the movable jaw plate 220 and the fixed jaw plate 230.

[0089] Drive unit 400, drive unit 400 is used to drive eccentric shaft 210;

[0090] The support base 500 is installed at the lower end of the frame 100 to fix and support the frame 100. The material guiding structure of the support base 500 is located directly below the gap between the moving jaw plate 220 and the fixed jaw plate 230.

[0091] The anti-blocking pusher part 600 includes a gear lever 610, a pusher bracket 620, and a pusher plate 630. The pusher bracket 620 is installed on one side of the support base part 500. The gear lever 610 is axially connected to the pusher bracket 620, and the upper end of the gear lever 610 is connected to one end of the eccentric shaft 210. The pusher plate 630 is set on the material guiding structure of the support base part 500 and is connected to the pusher bracket 620.

[0092] In this design, the upper end of the gear lever 610 of the anti-blocking pusher 600 is connected to one end of the eccentric shaft 210. The pusher plate 630 is mounted on the guide structure of the support base 500 and is connected to the push rod frame 620. The lower end of the gear lever 610 is engaged with the movable push rod of the push rod frame 620. When cleaning the crushed raw material accumulated at the guide structure, one end of the eccentric shaft 210 drives the upper end of the gear lever 610 to move left and right, causing the gear... The gear structure at the lower end of the lever 610 drives the movable push rod of the push rod frame 620 to move back and forth, thereby driving the pusher plate 630 to move left and right. This pushes the crushed raw material accumulated at the guide structure and pushes it out of the guide structure. This effectively prevents the crushed raw material from accumulating at the guide structure and prevents blockage. No manual cleaning is required, which improves efficiency and ensures production continuity. At the same time, no additional pushing equipment or additional energy is required for driving.

[0093] In some embodiments of the present invention, reference is made to... Figure 3-4 As shown, the eccentric shaft 210 includes:

[0094] Bearing housing 211 is mounted on the upper end of frame 100;

[0095] Eccentric shaft 212, both ends of eccentric shaft 212 are installed in bearing housing 211, and the jaw frame head end of moving jaw plate 220 is connected to eccentric shaft 212;

[0096] The first pulley 213 is installed at one end of the eccentric shaft 212;

[0097] Flywheel 214 is mounted on the other end of eccentric shaft 212;

[0098] A shaft post 215 is fixedly mounted on the side of the flywheel 214 and is used to connect to the upper end of the gear lever 610.

[0099] In some embodiments of the present invention, reference is made to... Figure 4-7 As shown, the adjustment seat 300 includes:

[0100] The seat block 310 is bolted to the rear end of the frame 100;

[0101] Elbow plate 320, one end of which is connected to the seat block 310, and the other end is connected to the lower end of the moving jaw plate 220;

[0102] The tie rod 330 has one end connected to the lower end of the seat block 310 and is equipped with a spring, and the other end is hinged to the lower end of the moving jaw plate 220.

[0103] Furthermore, the seat block 310 includes:

[0104] The base block 311 has bolts on both sides for connecting to the frame 100;

[0105] The front connecting cavity 312 is opened at the front end of the seat block 311 and is used for connecting the elbow plate 320. A bolt is threaded on the upper end of the front connecting cavity 312 to lock the part of the elbow plate 320 inserted into the front connecting cavity 312.

[0106] The adjustment cavity 313 is located at the rear end of the seat block 311 with the cavity opening facing upwards, and the adjustment cavity 313 is connected to the front end connecting cavity 312.

[0107] Adjustment shim 314 is detachably inserted into adjustment cavity 313.

[0108] Furthermore, the elbow plate 320 includes:

[0109] The I-beam connecting block 321 is inserted into the front connecting cavity 312 and locked by bolts on the front connecting cavity 312. The I-beam connecting block 321 also abuts and fixes the adjusting pad 314 in the adjusting cavity 313.

[0110] The elbow plate body 322 has engaging connectors 323 at both ends. Engaging slots 324 are movably connected to the engaging connectors 323. The engaging slots 324 are fixedly connected to one end of the I-beam connecting block 321 and the lower end of the moving jaw plate 220, respectively. The engaging slots 324 and the engaging connectors 323 form a joint structure. The joint structure formed by the engaging connectors 323 and the engaging slots 324 of the elbow plate 320 can adapt to the swing angle of the moving jaw plate 220, dispersing the impact force during crushing.

[0111] The adjusting seat 300 connects one end of the elbow plate 320 to the seat block 310 and the other end to the lower end of the moving jaw plate 220. An adjusting shim 314 is detachably inserted into the adjusting cavity 313 of the seat block 310. Compared with the traditional jaw crusher adjustment method that requires disassembling the frame 100 and stacking multiple layers of shims, the present invention only needs to increase or decrease the number of adjusting shims 314 in the adjusting cavity 313. The thickness of a single adjusting shim 314 can be set to specifications such as 2mm, 5mm, and 10mm to adjust the gap between the lower end of the moving jaw plate 220 and the fixed jaw plate 230. The adjustment process does not require disassembling the core components, which shortens the operation time and improves efficiency.

[0112] The core of gap adjustment is to control the particle size of raw material crushing by changing the gap between the lower ends of the moving jaw plate 220 and the fixed jaw plate 230, so as to adapt to the multi-specification requirements of aerated concrete block production.

[0113] The lower end position of the movable jaw plate 220 is determined by the support length of the elbow plate 320, and the support length of the elbow plate 320 is adjusted by adjusting the thickness of the shim 314. After the shim 314 is inserted into the adjustment cavity 313, it will push the I-beam connecting block 321 to move outward of the front connecting cavity 312, thereby driving the elbow plate 322 to push the lower end of the movable jaw plate 220 closer to the fixed jaw plate 230, thus reducing the discharge gap. Conversely, reducing the number of shims 314 will cause the lower end of the movable jaw plate 220 to move away from the fixed jaw plate 230 under the tension of the pull rod spring, thus expanding the discharge gap. After the I-beam connecting block 321 is inserted into the front connecting cavity 312, the locking bolt at the upper end will press the I-beam connecting block, and at the same time, the lower end of the I-beam connecting block will press against the shim 314.

[0126] A connecting slot 613 is provided at the upper end of the rocker arm 612, and the shaft post 215 is provided inside the connecting slot 613.

[0127] A connecting shaft 614 is connected at one end to the upper end of the half gear 611, and at the other end to the push rod bracket 620.

[0128] In some embodiments of the present invention, reference is made to... Figure 8-10 As shown, the push rod bracket 620 includes:

[0129] The connecting plate 621 is bolted to the side of the main support base 510;

[0130] Extension frame rod 622, which has an L-shaped structure, is fixedly welded to the side of the connecting frame plate 621;

[0131] Positioning sleeve 623 is fixedly welded to the lower end of extension rod 622;

[0132] The push rod body 624 is movably inserted into the positioning sleeve 623;

[0133] The tooth block 625 is disposed on the upper end face of the push rod body 624, and the half gear 611 meshes with the tooth block 625.

[0134] The circular plate position 626 is set on the connecting frame plate 621 and is used to connect one end of the connecting shaft 614.

[0135] In some embodiments of the present invention, reference is made to... Figure 8-10 As shown, the pusher plate 630 includes:

[0136] The cross arm plate 631 is fixedly welded to the side of the push rod body 624;

[0137] Push column 632 is welded to cross arm plate 631 and inserted into guide inclined plate 520;

[0138] The return spring 633 is mounted on the push post 632. One end of the return spring 633 is connected to the cross arm plate 631, and the other end is set on the outer side of the guide plate 520.

[0139] Push plate 634 is fixedly connected to the other end of push column 632 and is located on the inner side of guide plate 520.

[0140] The anti-blocking pusher 600 is linked with the gear lever 610 through the shaft 215 on the side of the flywheel 214, which directly converts the rotation of the eccentric shaft 212 into the reciprocating power of the pusher plate 630. The pushing action is synchronized with the crushing action, that is, the pushing frequency is consistent with the swing frequency of the moving jaw plate 220. No additional motor or cylinder is required, and the energy consumption of the equipment is reduced.

[0141] Working principle:

[0142] After the drive motor 410 is powered on, the output shaft drives the second pulley 420 to rotate. The second pulley 420 transmits power to the first pulley 213 through the belt 430. The protective cover 440 can prevent the belt from slipping or foreign objects from getting caught, ensuring transmission stability. The first pulley 213 is connected to the eccentric shaft 212, driving the eccentric shaft 212 to rotate in the bearing of the bearing housing 211. The eccentric section of the eccentric shaft 212 provides the power basis for the swing of the moving jaw plate 220. At the same time, the flywheel 214 at the other end of the eccentric shaft 212 rotates synchronously with the eccentric shaft 212, using the rotational inertia of the flywheel 214 to counteract the radial impact force generated by the rotation of the eccentric shaft 212.

[0143] The core of the crushing action is the synergistic effect of the moving jaw plate 220 and the fixed jaw plate 230, which achieves raw material crushing through a reciprocating cycle of squeezing closer to the material and unloading further away.

[0144] The moving jaw plate 220 and the fixed jaw plate 230 form a trapezoidal crushing chamber that is wider at the top and narrower at the bottom. After the raw material is fed into the feed inlet, it falls to the middle of the crushing chamber due to gravity.

[0145] When the eccentric shaft 212 rotates, its eccentric section drives the jaw head of the moving jaw plate 220 to make a circular motion. The lower end of the moving jaw plate 220 is connected to the adjusting seat 300 through the elbow plate 320, forming a composite trajectory of upper circular swing and lower limit swing. When the eccentric section of the eccentric shaft 212 rotates to the side closer to the fixed jaw plate 230, the moving jaw plate 220 moves closer to the fixed jaw plate 230, the crushing chamber volume shrinks, and the raw material is squeezed and sheared. When the eccentric section of the eccentric shaft 212 rotates to the side away from the fixed jaw plate 230, the moving jaw plate 220 moves away from the fixed jaw plate 230 under the spring tension of the tie rod 330, the crushing chamber volume expands, and the crushed raw material falls to the guide inclined plate 520 due to gravity.

[0146] The shaft 215 on the side of the flywheel 214 moves in a circular motion in sync with the flywheel 214. The shaft 215 is inserted into the connecting slot 613 of the gear lever 610, which drives the swing arm 612 to swing back and forth around the connecting shaft 614. The swing arm 612 is fixedly connected to the half gear 611, which in turn drives the half gear 611 to swing in sync.

[0147] The half gear 611 meshes with the tooth block 625 at the upper end of the push rod body 624. The oscillation of the half gear 611 is converted into the linear reciprocating motion of the tooth block 625, which in turn drives the push rod body 624 to move linearly along the positioning sleeve 623.

[0148] The push column 632 is connected to the push rod body 624 through the cross arm plate 631. The push column 632 passes through the reserved hole in the guide inclined plate 520. The push plate 634 at the other end of the push column 632 moves back and forth synchronously with the push column 632. When the push rod body 624 moves forward, the push plate 634 pushes the crushed raw material inside the guide inclined plate 520, pushing the accumulated raw material towards the discharge port. When the push rod body 624 moves backward, it drives the push column 632 back to its original position, and the return spring 633 pushes the cross arm plate 631 backward, driving the push plate 634 to quickly return to its original position, ready for the next push. The pushing frequency is consistent with the swing frequency of the moving jaw plate 220, ensuring that the crushed raw material is pushed out in time and avoiding accumulation.
