[0057] The utility model discloses a self -walking type shearing machine's plan view.

[0058] The utility model discloses a self -walking type shearing machine's plan view. Figure 1 、 Figure 2 As shown in the figure, the upper part is a shearing host, and the lower part is a crawler walking mechanism 8, and the two are detachably connected together.

[0059] The shearing host comprises a machine body 1, the machine body 1 is formed by a rack 11, an inclined feed hopper 12 is arranged in the rack 11, the front end of the feed hopper 12 is provided with a shearing area 13, and the shearing area 13 is externally provided with a discharge area 14.

[0060] The bottom of the feed hopper 12 of the shearing host is arranged to be inclined, so that the rear end of the feed hopper 12 is inclined upwards and outwards, forming an open material hopper bin, and materials of various lengths can be accommodated.

[0061] As shown in the figure, a pushing mechanism 2 is preferably arranged in the feed hopper 12. Figure 3 A pressing mechanism 3 is arranged at the front part of the feed hopper 12 and the rear side of the shearing area 13. A shearing mechanism 4 is arranged in the shearing area 13. A blocking mechanism 6 is preferably arranged in the discharge area 14.

[0062] As shown in the figure, the pushing mechanism 2 is arranged at the bottom of the feed hopper 12 and can be telescopically moved along the inclined direction of the feed hopper 12. Figure 5 The inclination angle of the feed hopper 12 is α, and 15°≤α≤35°.

[0063] The pushing mechanism 2 comprises a feeding frame 21 and a pushing driving element 22. The feeding frame 21 constitutes the bottom of the feed hopper 12, so the inclination angle of the feeding frame 21 is the angle α. The pushing driving element 22 is preferably a hydraulic oil cylinder. The piston rod of the oil cylinder is telescopically moved, thereby driving the feeding frame 21 to be telescopically moved.

[0064] Furthermore, the feeding rack 21 is a stepped plate with a pushing surface 211 facing the shearing zone 13. Preferably, there are multiple pushing surfaces 211, which are inclined downwards and form an acute angle with respect to the overall inclination direction of the feeding rack 21. Thus, when the weight of the material being sheared is insufficient to allow it to slide down automatically in the feed hopper 12, the telescopic movement of the feeding rack 21 will not only use the friction between the planes to push the material downwards, but also use the pushing surface 211 to catch the protrusion of the material and push it downwards to achieve feeding. When the feeding rack 21 moves upwards, because the pushing surface 211 is inclined downwards, it will not catch the material and bring it back.

[0065] The pressing mechanism 3 and the shearing mechanism 4 are preferably perpendicular to the pushing mechanism 2, and are therefore also inclined at an angle α relative to the vertical direction.

[0066] like Figure 4 As shown, the pressing mechanism 3 includes a pressing head 31 and a pressing drive element 32. The pressing head 31, near the shearing zone 13, has a pressing plane 311 parallel to the feeding frame 21, which reliably presses the material to be sheared for shearing by the shearing mechanism 4. Unlike conventional pressing heads, the pressing head 31 preferably has a stepped pressing head behind the pressing plane 311. This stepped pressing head has a stop surface 312 perpendicular or approximately perpendicular to the feeding frame 21, and a pre-compression surface 313 parallel or approximately parallel to the feeding frame 21. During operation, the pressing head 31 moves up and down, reliably pressing the material to be sheared onto the lower blade holder using the pressing plane 311 for easy shearing. Simultaneously, the stop surface 312 blocks subsequent material, and the pre-compression surface 313 performs step-by-step pre-compression, continuously reducing and concentrating the material's volume to form a smaller cross-section that enters the shearing zone 13. The pressing drive element 32 is preferably a hydraulic cylinder. The cylinder is inclined at an angle α relative to the vertical plane. The piston rod of the cylinder moves back and forth, which drives the pressing head 31 to move up and down to realize the pressing operation.

[0067] like Figure 4 As shown, the shearing mechanism 4, similar to a conventional gantry shear, has an upper blade holder 41 and a shearing drive element 42. The shearing side of the upper blade holder 41 is equipped with a detachable upper shearing blade 43. Correspondingly, a lower blade holder 44 is located at the front of the bottom of the feed hopper 12, and the shearing side of the lower blade holder 44 is equipped with a detachable lower shearing blade 45. The upper shearing blade 43 and the lower shearing blade 45 cooperate, with their shearing blades meshing to achieve the shearing operation. The shearing drive element 42 is preferably a hydraulic cylinder, which is inclined at an angle α relative to the vertical plane. The piston rod of the cylinder extends and retracts, thus driving the upper blade holder 41 to move up and down. The direction of movement of the upper blade holder 41 is inclined at an angle α relative to the vertical plane.

[0068] The upper surfaces of the lower blade holder 44 and the lower shearing blade 45 serve as a material receiving platform for the material to be sheared, and are flush with the bottom of the feed hopper 12 to facilitate material sliding in. At the same time, the material receiving platform is preferably parallel to the pressing plane 311, and the area between the two is the pressing and fixing area for the material to be sheared.

[0069] Because the self-propelled shearing machine of this utility model has an overall inclined feeding hopper 12, the material cut off during the shearing process of the shearing mechanism 4 will also fall automatically. After the shearing is completed, the shearing mechanism 4 resets, that is, after the upper blade holder 41 is raised, the pressing mechanism 3 also needs to be reset. Once the pressing head 31 is raised, the subsequent material to be cut in the feeding hopper 12 will slide down automatically under the action of gravity. Therefore, it is preferable to also set a material blocking mechanism 6 to control the sliding distance of the subsequent material to be cut, thereby controlling the length of the material to be cut off, so that the size of the cut material meets the requirements. If the material blocking mechanism 6 is not set, the subsequent material to be cut will slide down automatically under the action of gravity, and the size will be out of control, resulting in the inability to perform effective shearing.

[0070] like Figure 4 As shown, the material blocking mechanism 6 includes a material blocking plate 61 and a material blocking drive element 62. Under the drive of the material blocking drive element 62, the material blocking plate 61 can block in front of the shearing zone 13 or away from the shearing zone 13 to facilitate the material falling. The end of the material blocking plate 61 is provided with a material supporting plate 611. When the material supporting plate 61 moves with the material blocking plate 61 to the vicinity of the shearing zone 13, it can block or support the material to be sheared.

[0071] In this embodiment, the upper part of the baffle plate 61 is hinged to the upper part of the discharge area 14 of the frame 11 via the baffle hinge shaft 63; the baffle drive element 62 is preferably a hydraulic cylinder. The extension and retraction movement of the piston rod of the cylinder will drive the baffle plate 61 to swing around the baffle hinge shaft 63, so that the lower part of the baffle plate 61 and the material receiving plate 611 are close to the shearing area 13 to receive and block the material, or move away from the shearing area 13, so that the discharge area 14 and the shearing area 13 are connected, which facilitates the material to fall.

[0072] As a further improvement to this utility model, such as Figure 7 , Figure 8 As shown, a side pressing mechanism 5 is also provided at the lower part of the feed hopper 12. The side pressing mechanism 5 is located on both sides of the lower part of the feed hopper 12, including a side pressing head 51 and a side pressing drive element 52. Under the drive of the side pressing drive element 52, the side pressing head 51 can move into the interior of the feed hopper 12 to gather the material located at the lower part of the feed hopper 12 from both sides to the middle, which is convenient for shearing.

[0073] Furthermore, the side pressure head 51 is a swinging pressure head. The front end of the side pressure head 51 is hinged to the inner front part of the feed hopper 12, near the middle, via the side pressure hinge shaft 53. The side pressure head 51 has a guide pressing surface 511 and a retaining arc surface 512. The guide pressing surface 511 is located inside the feed hopper 12. The side pressure driving element 52 is preferably a hydraulic cylinder. The extension and retraction of the piston rod of the cylinder will drive the side pressure head 51 to swing around the side pressure hinge shaft 53. When the side pressure driving element 52 drives the side pressure head 51 outward and stabilizes it, the guide pressing surface 511 is tilted outward. Figure 8 As shown by the dashed line, a funnel-shaped opening is formed at the front of the feed hopper 12 to guide the material in the feed hopper 12 towards the center and into the shearing zone 13. At this time, the baffle arc surface 512 is located on the outside of the feed hopper 12. When the side pressure drive element 52 drives the side pressure head 51 inward, the guide pressure surface 511 swings inward, further concentrating the material between the guide pressure surfaces 511 on both sides towards the center. At this time, the baffle arc surface 512 gradually enters the feed hopper 12 and blocks the material on the rear side.

[0074] The self-propelled shearing machine of this invention operates by roughly following these cyclical steps:

[0075] Step 1, feeding; at this time, the pressing head 31 of the pressing mechanism 3 rises, the upper knife seat 41 of the shearing mechanism 4 rises, and the side pressing head 51 of the side pressing mechanism 5 swings outward, forming a horn-shaped guide port at the front of the feeding hopper 12; the feeding frame 21 of the pushing mechanism 2 also preferably extends out; while the baffle plate 61 of the blocking mechanism 6 lowers down, approaching the shearing zone 13; the external gripping mechanism puts the material to be sheared into the feeding hopper 12, and the material slides downward under the action of gravity, and some of the material is guided by the horn-shaped guide port, passes through the shearing zone 13, and is blocked by the baffle plate 61;

[0076] Step 2, feeding; the pushing mechanism 2 moves, causing the feeding frame 21 to reciprocate, driving more material downwards and through the shearing zone 13; at the same time, in coordination with the action of the pushing mechanism 2, the side pressure head 51 of the side pressure mechanism 5 swings inwards, gathering the material towards the center, so that more material can pass through the shearing zone 13.

[0077] Step 3, pressing and shearing; finally, the pressing mechanism 3 and the shearing mechanism 4 are activated. The pressing head 31 descends first (the pressing head 31 is located between the side pressing heads 51 on both sides), pressing the material in the shearing zone 13 onto the lower blade holder 44. Then the upper blade holder 41 is driven to shear downwards. The upper shearing blade 43 and the lower shearing blade 45 engage with each other, cutting off the material that has passed through the shearing zone 13 and exceeded the lower shearing blade 45.

[0078] The baffle plate 61 of the baffle mechanism 6 rises after the pressing head 31 is lowered and pressed, so as to facilitate the discharge of the cut material into the discharge area 14.

[0079] After shearing, the upper tool holder 41 can be raised for resetting.

[0080] Step 4, continue feeding; after the discharging is completed, the baffle plate 61 of the baffle mechanism 6 is lowered to approach the shearing area 13 to close the discharging area 14; then, the pressing head 31 of the pressing mechanism 3 is raised to release the pre-compressed material into the shearing area 13;

[0081] Then, steps 2 and 3 are repeated, that is, the feeding, pressing, shearing and discharging are completed.

[0082] The external grabbing mechanism adds material in time according to the material amount in the feeding hopper 12, so that the shearing can be continuously performed.

[0083] The shearing host of the utility model has been designed to be lightweight, facilitating transportation, but the overall weight is still heavy, and when placed on a transport flat car or a crawler walking mechanism 8, a heavy crane may be needed, which undoubtedly increases the hoisting cost; therefore, for occasions that need to be frequently disassembled and hoisted, at least four liftable legs 7 are arranged in the shearing host of the utility model, which are located around the shearing host body.

[0084] Preferably, the liftable legs 7 are hinged to the rack 11; when the shearing host of the utility model is transported or used, the liftable legs 7 are rotated and stored in the rack 11, thereby reducing the volume and not producing exposed objects to affect the safety of transportation and use; when the shearing host of the utility model needs to be disassembled, the liftable legs 7 are rotated out of the rack 11, and then the telescopic part of the liftable legs 7 is extended downward to lift the body of the shearing host of the utility model to a suspended state, thereby facilitating the transport flat car or the crawler walking mechanism 8 to enter and exit from below.

[0085] Due to the limited width of the shearing host, when the liftable legs 7 are extended, the distance between the liftable legs 7 on both sides may not be sufficient for the crawler walking mechanism 8 to directly enter. Figure 1 As shown, the crawler belts on both sides of the crawler walking mechanism 8 generally exceed the width of the shearing host to obtain a more stable chassis to drive the shearing host to move; the crawler walking mechanism 8 is fixed along the length direction of the shearing host.

[0086] At this time, the liftable legs 7 need to be extended outward to obtain more space between the two liftable legs 7 in the width direction, facilitating the crawler walking mechanism 8 to enter / exit below the shearing host; therefore, it is more necessary for the liftable legs 7 to be folded and contracted into the rack 11 to facilitate transportation.

[0087] Alternatively, as shown in Figure 3As shown, the crawler traveling mechanism 8 is provided with a rotary table 9 between the shearing main machine; in this way, when the liftable supporting legs 7 are extended, the crawler traveling mechanism 8 can drive into the bottom of the shearing main machine between the two liftable supporting legs 7 in the length direction, then the liftable supporting legs 7 are lowered to lower the shearing main machine on the rotary table 9, the rotary table 9 drives the shearing main machine to rotate 90°, so that the shearing main machine is aligned with the length direction of the crawler traveling mechanism 8, and finally the shearing main machine is further lowered or is padded with a pad to fix the bottom of the rack 11 of the shearing main machine and the rack body of the crawler traveling mechanism 8, so as to facilitate the movement of the crawler traveling mechanism 8 to drive the shearing main machine, and after moving to the position, the shearing operation can be carried out.

[0088] The preferred embodiments of the utility model have been specifically described above, but the utility model is not limited to the described embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the utility model, and these equivalent modifications or replacements are all included in the range defined by the claims of the present application.
