Technical Field

[0001] This utility model relates to the field of crushing equipment, and in particular to a mobile high-efficiency crushing device. Background Technology

[0002] When ore is first mined, the pieces are relatively large and need to be crushed before further processing. During the ore crushing process, crushing equipment is used to crush large pieces of material into granular materials that meet the requirements. It is widely used in mining, construction, road construction and other fields.

[0003] Existing crushing devices are mostly fixed structures, which are inconvenient to move and difficult to adapt to the needs of different working sites. At the same time, the crushing chamber structure of some crushing devices is not reasonably designed, resulting in low material crushing efficiency. Therefore, a crushing device that is flexible to move and has high crushing efficiency is needed to solve the above problems. Utility Model Content

[0006] A fixed jaw plate is installed on the front side of the crushing chamber above the guide plate, and a movable jaw plate corresponding to the fixed jaw plate is rotatably installed inside the crushing chamber. The upper end of the movable jaw plate is rotatably connected to the inner wall of the crushing chamber through a movable shaft. A connecting seat is hinged to the middle of the rear side of the movable jaw plate. A sliding guide rod is vertically installed on the side of the connecting seat. A fixed rod is installed on the inner wall of the crushing chamber. One end of the sliding guide rod slides through the middle of the fixed rod and is threadedly connected to a limit plate. A spring is sleeved on the outside of the sliding guide rod between the limit plate and the fixed rod.

[0007] The interior of the cabin is also equipped with a drive mechanism for reciprocatingly pushing the lower end of the movable jaw plate toward the fixed jaw plate.

[0008] As a further technical solution of this utility model, the drive mechanism includes a drive motor, a main pulley, a synchronous belt, a secondary pulley, a main shaft, and a top block;

[0009] The drive motor is mounted on the bottom of the machine compartment via a bracket, and the output end of the drive motor is connected to the main pulley. The main pulley and the auxiliary pulley are connected by a synchronous belt drive, and a tension adjustment wheel can be configured on the synchronous belt.

[0010] As a further technical solution of this utility model, the auxiliary pulley is rotatably disposed on the outer side wall of the crushing chamber, the main shaft is rotatably disposed on the inner side of the crushing chamber, and one end of the main shaft passes through the crushing chamber and is fixed to the middle of the side of the auxiliary pulley.

[0011] As a further technical solution of this utility model, the top block is vertically fixed in the middle of the surface of the main shaft, and one end of the top block is set in an arc.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution for a mobile high-efficiency crushing device: a mobile high-efficiency crushing device, including a tracked mobile mechanism 1 and a machine compartment 3 installed on the upper end of the tracked mobile mechanism 1. The tracked mobile mechanism 1 adopts a conventional tracked mobile device to provide the device with flexible mobility, which can easily cope with complex terrains such as mines and construction sites, and meet the needs of rapid transfer to different work sites. The machine compartment 3 is also equipped with a control cabinet 33, and a handrail 31 is fixed on the upper rear side of the machine compartment 3. Multiple control levers 32 are set on the top of the machine compartment 3, and a station plate 2 is set on the lower rear side of the machine compartment 3. The multiple control levers 32 facilitate the operator to accurately adjust various parameters. The handrail 31 on the upper rear side and the station plate 2 on the lower rear side cooperate with each other to provide the operator with a safe and stable operating platform.

[0028] like Figure 2 and 7 As shown, a crushing chamber 5 is provided on the upper front side of the machine compartment 3. The crushing chamber 5 adopts a split frame structure and is fixed by high-strength bolts to avoid the influence of welding stress on the strength of the equipment. It is also convenient for transportation and on-site installation. A feed hopper 4 is provided at the top of the crushing chamber 5, and a guide plate 61 is provided at the discharge port of the crushing chamber 5. A belt feeder 6 is provided on the front side of the machine compartment 3. When the movable jaw plate 52 is not squeezed by the top block 74, the discharge channel formed between it and the bottom of the fixed jaw plate 51 is located directly above the guide plate 61. The guide plate 61 is inclined, and the discharge port of the guide plate 61 is located directly above the feed end of the belt feeder 6. The inclined guide plate 61 can accurately guide the crushed material onto the belt feeder 6 to achieve continuous material conveying.

[0029] like Figure 4-7As shown, a fixed jaw plate 51 is installed on the front side of the crushing chamber 5 above the guide plate 61. A movable jaw plate 52 corresponding to the fixed jaw plate 51 is also rotatably installed inside the crushing chamber 5. The upper end of the movable jaw plate 52 is rotatably connected to the inner wall of the crushing chamber 5 via a movable shaft 58. A connecting seat 53 is hinged to the middle of the rear side of the movable jaw plate 52. A sliding guide rod 54 is vertically installed on the side of the connecting seat 53. A fixed rod 57 is installed on the inner wall of the crushing chamber 5. One end of the sliding guide rod 54 slides through the middle of the fixed rod 57 and is threadedly connected to a limit plate 55. A spring 56 is sleeved on the outside of the sliding guide rod 54 between the limit plate 55 and the fixed rod 57. When the top block 74 is released from the pressure on the movable jaw plate 52, the spring 56 can drive the movable jaw plate 52 to quickly reset. Moreover, the limited sliding of the sliding guide rod 54 on the fixed rod 57 can ensure the stability of the reset of the movable jaw plate 52 and ensure the continuity of the crushing operation.

[0030] The interior of the crushing chamber 3 is also equipped with a drive mechanism for reciprocatingly pushing the lower end of the movable jaw plate 52 toward the fixed jaw plate 51. The drive mechanism includes a drive motor 7, a main pulley 71, a synchronous belt, a secondary pulley 72, a main shaft 73, and a top block 74. The drive motor 7 is mounted on the bottom of the interior of the crushing chamber 3 via a bracket, and the output end of the drive motor 7 is connected to the main pulley 71. The main pulley 71 and the secondary pulley 72 are connected by a synchronous belt drive, and a tension adjustment wheel can be configured on the synchronous belt. The secondary pulley 72 is rotatably mounted on the outer wall of the crushing chamber 5, and the main shaft 73 is rotatably mounted on the outer wall of the crushing chamber 5. Inside the crushing chamber 5, one end of the main shaft 73 passes through the crushing chamber 5 and is fixed to the middle of the side of the auxiliary pulley 72. The main pulley 71 is driven to rotate by the drive motor 7, and the rotation is transmitted to the auxiliary pulley 72 via the synchronous belt. This drives the main shaft 73 and the top block 74 to rotate. The arc design of the top block 74 can reduce the friction with the movable jaw plate 52, so as to achieve smooth reciprocating compression of the lower end of the movable jaw plate 52. This forms a continuously opening and closing "steel jaw" between the movable jaw plate 52 and the fixed jaw plate 51, so as to achieve the cyclic reciprocating compression, crushing and release of materials. The tension adjustment wheel configured on the synchronous belt can ensure the stability of the transmission.

[0031] The top block 74 is vertically fixed to the middle of the surface of the main shaft 73, and one end of the top block 74 is set with an arc surface. When the top block 74 is flipped to a horizontal state and corresponds to the lower end of the movable jaw plate 52, it will squeeze the movable jaw plate 52 and make it move closer to the fixed jaw plate 51 for crushing the material. The opposite surfaces of the fixed jaw plate 51 and the movable jaw plate 52 are provided with V-shaped crushing jaw teeth, and a V-shaped crushing cavity is formed between the fixed jaw plate 51 and the movable jaw plate 52. The discharge port of the feed hopper 4 is located directly above the V-shaped crushing cavity. The V-shaped crushing cavity is an asymmetrical structure, which not only increases the width and depth of the feed port, allowing for the processing of larger materials, but also ensures that the material is always effectively squeezed during the downward movement of the cavity, avoiding blockage at the bottom of the cavity, and significantly improving the material throughput and crushing uniformity. The fixed jaw plate 51, the movable jaw plate 52, the movable shaft 58, and the top block 74 are all made of high-quality cast steel, which has high strength and high wear resistance, effectively extending the service life of the device.

[0032] The working principle of this utility model is as follows: When in use, the tracked moving mechanism 1 can be moved by the control lever 32 to move the device to the designated position, and then the material is fed into the crushing chamber 5 through the feed hopper 4 for crushing operation.

[0033] Furthermore, the drive motor 7 is started to drive the main pulley 71 to rotate, and the power is transmitted to the auxiliary pulley 72 via the synchronous belt. The tension adjustment wheel configured on the synchronous belt can ensure that the transmission process is stable and without slippage. The auxiliary pulley 72 drives the main shaft 73 that passes through the crushing chamber 5 to rotate, and the top block 74 on the surface of the main shaft 73 rotates together. When the top block 74 flips to the horizontal state, it squeezes the lower end of the movable jaw plate 52, making it move closer to the fixed jaw plate 51, thereby realizing the compression, bending and shearing crushing of the material.

[0034] When the top block 74 is disengaged from the extrusion, the spring 56 pulls the sliding guide rod 54 to reset, the movable jaw plate 52 moves away from the fixed jaw plate 51, and the crushed material falls into the inclined guide plate 61 through the discharge channel under the action of gravity, and is finally precisely guided to the belt feeder 6 to complete the complete work of feeding → extrusion → discharge.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
