[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] The following is combined Figures 1-4 This invention describes the crushing station provided by this utility model.

[0035] This application provides a crushing station, such as Figures 1 to 4 As shown, the crushing station has a transfer state and a transport state, including: a crushing station body, a frame 1, and hydraulic outriggers 2. The hydraulic outriggers 2 include: a drive unit 21, a support plate 22, an inner component 23, and an outer component 24; the crushing station body is mounted on the frame 1, the outer component 24 is fixed to the frame 1, and the outer component 24 has a cavity inside. One end of the inner component 23 is connected to the support plate 22, and the other end of the inner component 23 is movably disposed in the cavity. The drive unit 21 is connected between the outer component 24 and the inner component 23; in the transfer state, the drive unit 21 drives the inner component 23 to move relative to the outer component 24 to the extended position, so that the support plate 22 is supported on the ground; in the transport state, the drive unit 21 drives the inner component 23 to move relative to the outer component 24 to the retracted position, so that the support plate 22 is lifted off the ground.

[0036] In this embodiment, the main body of the crushing station adopts a modular structure, meaning that the various components within the main body can be quickly disassembled and assembled to adapt to different working conditions. The main body of the crushing station is used for crushing materials. The frame 1 supports the main body of the crushing station, and the hydraulic outriggers 2 support the frame 1 and the main body of the crushing station during transfer and are retracted during transport. The drive unit 21 drives the inner assembly 23 to move relative to the outer assembly 24, thereby moving the support plate 22 and controlling the transfer of the crushing station.

[0037] When the crushing plant is in normal production position, the hydraulic outriggers 2 are fully retracted, the support plate 22 is off the ground, and the weight of the entire machine is supported by the frame 1. When transporting the crushing plant, control the drive unit 21 to push the inner assembly 23 outward along the inner cavity of the outer assembly 24. The support plate 22 first lightly touches the ground, then continues to apply pressure, causing the drive unit 21 to push the inner assembly 23 outward along the inner cavity of the outer assembly 24. The inner assembly 23 and outer assembly 24 continue to move in opposite directions, continuing the lifting process. When lifted to approximately 1300mm off the ground, a transport truck (1000mm high) can drive unimpeded under the frame 1. Control the drive unit 21 to retract, and the inner assembly 23 begins to retract. The frame 1 slowly descends until the entire frame 1 is placed on the truck. At this point, the drive unit 21 can be further retracted to return the inner assembly 23 to the end of its stroke, preventing accidental extension during transport, thus completing the loading. The crushing plant leaves the site as a whole, requiring no lifting equipment throughout the process. Once you arrive at the new site, simply reverse the above procedure to resume production.

[0038] The crushing plant provided by this utility model utilizes hydraulic outriggers 2 to directly support the entire frame 1 and the main body of the crushing plant. The drive unit 21 can be used to lift and lower the frame 1 and the main body of the crushing plant, allowing transport equipment to directly drive into or out of the bottom of the equipment. The hydraulic outriggers 2 are then retracted, allowing the entire machine to rest on the truck bed. This eliminates the traditional crane lifting process, significantly reducing relocation preparation time and costs. It also avoids complex processes such as manual crane operation and multiple-point securing.

[0039] In some embodiments, such as Figures 1 to 4 As shown, the drive component 21 includes a cylinder body and a piston rod. The cylinder body is arranged along the cavity axis of the outer component 24 and is firmly fixed to the inner wall of the cavity by screws or welding to achieve a rigid connection with the outer component 24; one end of the piston rod is slidably placed in the cylinder body, and the other end is hinged to the upper end of the inner component 23 by a pin or ball joint structure.

[0040] When hydraulic oil is pumped into the cylinder through an external hydraulic pump station, hoses, and control valve assembly, a pressure difference is generated on both sides of the piston, pushing the piston rod to extend axially. The extension of the piston rod is transmitted through the hinge point, causing the inner component 23 to slide axially outward within the cavity of the outer component 24 until the support plate 22 is firmly supported on the ground, completing the lifting process. Conversely, when the hydraulic oil flows back in the opposite direction, the piston rod retracts under the action of hydraulic pressure and the weight of the frame 1, and the inner component 23 retracts into the cavity of the outer component 24, causing the support plate 22 to lift off the ground and the hydraulic outrigger 2 to fold. This structure not only completely hides the hydraulic cylinder inside the outer component 24, improving the protection level and aesthetics, but also releases the lateral force caused by uneven ground or slight deformation of the frame 1 through the hinge, preventing jamming or biting between the inner component 23 and the outer component 24, ensuring that the entire lifting process is smooth, safe, and reliable.

[0041] In some embodiments, such as Figures 1 to 4 As shown, a mounting boss 221 is formed on the side of the support plate 22 near the inner sleeve 23, and a mounting groove 222 is formed in the mounting boss 221; a connector 231 is formed at one end of the inner sleeve 23, and the connector 231 is fixed in the mounting groove 222 to be connected to the support plate 22 via the mounting boss 221.

[0042] In this embodiment, the support plate 22 is a rectangular plate with a wear-resistant and anti-slip mesh or vulcanized rubber pad welded to its lower surface to increase friction with the ground and protect the road surface. Its upper surface (the side facing the inner component 23) is integrally machined or forged to form an upwardly protruding mounting boss 221. This mounting boss 221 is a cylindrical or rectangular cross-section boss body with a mounting groove 222 vertically formed at its center. The cross-sectional shape of the mounting groove 222 matches the insertion piece 231 at the end of the inner component 23, and can be a rectangular blind hole, a spline hole, or a round hole with a keyway; the groove wall is surrounded by an annular sealing groove, into which an O-ring or dustproof ring can be embedded to prevent mud and sand from entering.

[0043] The inner fitting 23 is a thick-walled seamless steel pipe or rectangular tube, with its ends formed into plug-in parts 231 through heat shrinking, forging, or machining. The outer contour of the plug-in part 231 and the mounting groove 222 are fitted together to ensure no relative wobbling under load. The outer surface of the plug-in part 231 can be further machined with longitudinal keyways or external splines, which mate with the internal splines of the mounting groove 222 to achieve torque transmission.

[0044] It should be noted that the hydraulic outrigger 2 also includes a fixing component, and the connector 231 is detachably mounted in the mounting groove 222 via the fixing component. During on-site assembly, the connector 231 is first aligned with the mounting groove 222 on the mounting boss 221 of the support plate 22 and inserted into place; then, the connector 231 is further secured by the fixing component to prevent it from loosening during operation. When the support plate 22 needs to be replaced, the fixing component can be removed, and the connector 231 can be taken out of the mounting groove 222 for quick removal, enabling on-site component replacement and maintenance.

[0045] In some embodiments, such as Figures 1 to 4 As shown, the fasteners include a bolt 25 and a nut 26. The first end of the bolt 25 is engaged outside the mounting groove 222, and the second end of the bolt 25 penetrates the side wall of the mounting groove 222 and is at least partially disposed within the mounting groove 222. The nut 26 is rotatably disposed at the second end of the bolt 25.

[0046] In this embodiment, bolt 25 is an elbow bolt, which consists of a long threaded section and a short elbow, both integrally forged. The long threaded section passes sequentially through the transverse through hole on the side wall of the mounting boss 221 and the locking hole on the side wall of the connector 231. The short elbow is secured to the outer side of the mounting boss 221, with its outer end face flush with or slightly lower than the outer surface of the mounting boss 221 to avoid impact. A standard hexagonal nut or a self-locking nut is screwed into the end of the threaded section that protrudes into the mounting groove 222. After tightening, the end face of the nut 26 presses against the side wall of the connector 231, achieving axial locking. Since the elbow's rotation is restricted by the positioning groove, during assembly, only one hand is needed to fix the elbow, and the other hand is needed to tighten / loosen the nut 26, eliminating the need for additional tools to fix the bolt head and significantly improving on-site operation efficiency. During disassembly, simply loosen and remove the nut 26, and pull the elbow bolt outward to release the locking of the connector 231.

[0047] Furthermore, such as Figures 1 to 4 As shown, the second end of the bolt 25 is provided with a pin hole, and the fastener also includes a cotter pin 27. The cotter pin 27 passes through the pin hole to bend and tighten the nut 26. During assembly, the long threaded section of the bent bolt is first passed through the through hole on the side wall of the mounting boss 221 and the locking hole of the connector 231 in sequence; the nut 26 is screwed in and tightened to the specified torque, so that the end face of the nut 26 is in close contact with the side wall of the connector 231; the angle of the nut 26 is further finely adjusted so that any radial groove on it is aligned with the pin hole at the end of the bolt; the cotter pin 27 is passed through the pin hole and pressed against the outer end face of the nut 26 to form a mechanical anti-loosening lock.

[0048] Because the entire crushing plant is quite heavy, such as Figure 1 and Figure 2 As shown, for the sake of connection stability, the hydraulic outrigger 2 also includes a connecting bracket 28. One side of the connecting bracket 28 is connected to the outer casing 24, and the other side of the connecting bracket 28 is connected to the frame 1.

[0049] In this embodiment, the connecting frame 28 is a box-shaped welded frame or an integral cast-welded hybrid structure. The shape of the connecting frame 28 matches the cross-section of the longitudinal / transverse beams at the corresponding positions of the frame 1, enabling seamless connection. The connecting frame 28 upgrades the original line-contact weld stress to surface-to-surface three-dimensional stress, significantly improving the connection stability and fatigue life between the hydraulic outrigger 2 and the frame 1, providing reliable protection for the safe support of the overall load and frequent relocation.

[0050] In some embodiments, such as Figures 1 to 4As shown, multiple hydraulic outriggers 2 are typically provided, arranged around the perimeter of the frame 1. The number of hydraulic outriggers 2 can be selected based on the load weight. For example, for a 30-ton crushing plant, four hydraulic outriggers 2 can be installed, arranged in a rectangular four-corner configuration. For a 50–80t crushing plant, six outriggers can be installed (two in the front and four in the back, or three in the front and three in the back), forming a hexagonal ring. For crushing plants over 100t, eight or twelve outriggers can be installed, arranged in a double rectangular or star-shaped pattern, ensuring that the maximum load on a single outrigger does not exceed 70% of its rated load capacity.

[0051] like Figures 1 to 4 As shown, the frame 1 is suitable for mounting on a transport vehicle; in the transfer state, the hydraulic outriggers 2 support the frame 1 upwards, separating the frame 1 from the transport vehicle; in the transport state, the hydraulic outriggers 2 retract, allowing the frame 1 to be mounted on the transport vehicle.

[0052] In this embodiment, when the crushing station is in normal production, the hydraulic outriggers 2 are fully retracted, the support plate 22 is off the ground, and the weight of the entire machine is supported by the frame 1. When transporting the crushing station, the drive unit 21 is controlled to push the inner component 23 outward along the inner cavity of the outer component 24. The support plate 22 first lightly touches the ground, and then continues to apply pressure to make the drive unit 21 push the inner component 23 outward along the inner cavity of the outer component 24. The inner component 23 and the outer component 24 continue to move in opposite directions, continuing to lift. When it is lifted to about 1300mm off the ground, the transport truck (1000mm high) can drive under the frame 1 without obstruction. The drive unit 21 is then controlled to retract, and the inner component 23 begins to retract. The frame 1 slowly descends until the entire frame 1 is placed on the truck. At this time, the drive unit 21 can be controlled to retract further, so that the inner component 23 returns to the end of its stroke to prevent accidental extension during transport, thus completing the loading. The crushing station leaves the site as a whole, without the need for any lifting equipment.

[0053] Upon arrival at the new site, park the transport truck carrying the crushing station at the designated production position. After the transport truck comes to a complete stop, briefly jog the drive unit 21 to extend the inner component 23 outward from the end of its stroke, releasing the transport lock state, and simultaneously confirm that the hydraulic system pressure is normal. Simultaneously activate all drive units 21, pushing the inner component 23 slowly outward along the inner cavity of the outer component 24, allowing the frame 1 to support the ground and lift the entire unit. After the frame 1 is fully supported by the hydraulic outriggers 2, slowly reverse the transport truck away from under the frame 1, ensuring that there is no interference between the frame 1 and the truck. Simultaneously control all drive units 21 to retract, and the inner component 23 drives the frame 1 to descend at a uniform speed until the support plate 22 is about 200mm from the ground, then pause to check the levelness of the frame 1. Continue retracting the drive units 21, and after the support plate 22 lightly touches the ground, observe the contact between the crushing station and the ground in real time. When the crushing station is fully in contact with the ground, fully retract the inner component 23 to the end of its stroke, and the support plate 22 is completely off the ground, thus resuming production readiness.

[0054] Based on the above embodiments, such as Figures 1 to 4 As shown, the main body of the crushing station includes: a feeder 3, a crusher 4, and a conveyor belt 5 arranged sequentially along the processing direction. The feeder 3 is used for feeding and screening the stone. The crusher 4 is used for crushing the screened stone. The conveyor belt 5 is used for transporting the crushed stone.

[0055] In this embodiment, a loader or dump truck pours raw stones into the feeder 3. The feeder 3 vibrates the feed chute to convey the stones forward evenly. Qualified material of the set particle size falls directly into the receiving port of the crusher 4; material larger than the set particle size is conveyed away by the tail belt, thereby reducing the load on the crusher 4, reducing energy consumption, and preventing blockage by excessively large pieces. Qualified material from below the bar screen of the feeder 3 directly enters the crusher 4, where it is crushed to the designed particle size after high-speed impact and compression. The crushed mixture falls through the discharge port at the bottom of the crusher 4 and enters the conveyor belt 5. The crushed stone is lifted by the conveyor belt 5 and thrown to the downstream stockpile or secondary screening.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
