[0036] Embodiment 1

[0037] Referring to Figure 1 , Figure 2 and Figure 3 As shown, a scraper for a slag salvage machine includes a scraper mechanism 100 and a material shaking mechanism 200. The scraper mechanism 100 can be used to scrape the slag inside the slag salvage machine. At the same time, when the scraper mechanism 100 discharges materials, the material shaking mechanism 200 can be used to promote the vibration of the scraper mechanism 100, so as to promote the dropping of the slag on the scraper mechanism 100.

[0038] Specifically, the scraper mechanism 100 includes a bottom plate 101, wherein a U-shaped groove is provided on the lower surface of the bottom plate 101, a side plate 102 is fixedly installed on one side of the bottom plate 101, the side plate 102 is arranged at 90 degrees with the bottom plate 101, and the side plate 102 and the bottom plate 101 are arranged in an integrated manner, a surface plate 103 is slidably installed on the upper surface of the bottom plate 101, a through groove 102a is penetrated on the side plate 102, one end of the surface plate 103 penetrates the through groove 102a and is slidably connected to the side plate 102, and the bottom plate 101 is provided with a U-shaped groove. Extension plates 104 are movably connected on both sides of the plate 101. The extension plates 104 are foldably connected to the bottom plate 101. The extension plates 104 are used to expand the scraping area. A buffer component 105 is provided between the bottom plate 101 and the surface plate 103. The buffer component 105 can specifically be an elastic member, which is used to buffer the force when the surface plate 103 abuts against the bottom of the slag removal machine, and to provide buffering protection for the surface plate 103 to avoid breakage when the surface plate 103 suddenly abuts against the bottom of the slag removal machine.

[0039] Specifically, the material shaking mechanism 200 includes a pushing component 201 arranged under the base plate 101, wherein the pushing component 201 can be specifically a push rod 201a, and a one-way toggle component 202 is provided under the base plate 101. The driving end of the one-way toggle component 202 can be connected to one end of the push rod 201a, and the push rod 201a is used to push the one-way toggle component 202 to move. An impact component 203 is provided on one side of the one-way toggle component 202. When the push rod 201a pushes the one-way toggle component 202 to perform the toggle operation, the one-way toggle component 202 can be used to drive the impact component 203 to move, and the impact component 203 can be used to impact and vibrate the surface plate 103 from the bottom of the surface plate 103, so that the surface plate 103 can be vibrated, effectively promoting the impurities attached to the surface plate 103 to fall off.

[0040] Furthermore, the surface plate 103 includes a plate body 103a, wherein the plate body 103a is a rectangular plate, and an arc scraper 103b is arranged at one end of the plate body 103a, the arc scraper 103b is integrated with the plate body 103a, and the arc scraper 103b extends to one side of the bottom plate 101, wherein the arc scraper 103b can be made of wear-resistant rubber material, which can reduce the wear when it contacts the bottom of the slag scoop machine and extend its service life.

[0041] Furthermore, the buffer assembly 105 includes a limit plate 105b arranged at the bottom end of the base plate 101, wherein the limit plate 105b is fixedly installed inside a U-shaped groove opened on the lower surface of the base plate 101, and a buffer spring 105a is installed on one side of the limit plate 105b. There are several buffer springs 105a, one end of the several buffer springs 105a is fixedly connected to the limit plate 105b, and the other end of the several buffer springs 105a is fixedly connected to the surface of one side of the arc scraper 103b. When the scraper mechanism 100 abuts against the bottom end of the slag remover under the drive of the chain, the arc scraper 103b can be abutted against the bottom end of the slag remover first, and then the buffer spring 105a is used to buffer the force of the surface plate 103 abutting against the bottom end of the slag remover to prevent it from being deformed by sudden force.

[0042] Operation process: When the scraper mechanism 100 abuts against the bottom end of the slag picker under the drive of the chain, the arc scraper 103b can first be made to abut against the bottom end of the slag picker, and then the buffer spring 105a is used to buffer the force of the surface plate 103 abutting against the bottom end of the slag picker to prevent it from being deformed by sudden force. At this time, the buffer spring 105a receives the extrusion force and contracts. When the bottom end of the arc scraper 103b abuts against the bottom end of the inside of the slag picker, under the action of the buffer spring 105a, one end of the surface plate 103 can pass through the through slot 102a and move to the side of the side plate 102, and at the same time, the push rod 201a can By extending and moving to one side of the one-way toggle component 202, when the bottom end of the arc scraper 103b is separated from the bottom end of the slag remover, the buffer spring 105a can push the surface plate 103 to move away from the bottom plate 101, so that the surface plate 103 moves toward the slag discharge port, which is more convenient for discharging the slag on the surface plate 103. At the same time, the push rod 201a can shrink and pull the one-way toggle component 202 to move, and the one-way toggle component 202 is used to drive the impact component 203 to move and impact the surface plate 103, thereby accelerating the falling of the slag on the surface plate 103, quickly unloading, and facilitating use.

[0043] Example 2

[0044] Reference Figure 3 — Figure 7 As shown, this embodiment is different from the first embodiment in that: the pushing component 201 includes a push rod 201a arranged on one side of the arc scraper 103b and connected to the arc scraper 103b, one end of the push rod 201a is fixedly connected to one side of the arc scraper 103b, the other end of the push rod 201a passes through the limit plate 105b and is slidably connected to the limit plate 105b, and one end of the push rod 201a is fixedly connected to the push plate 201b, when the arc plate pushes the push rod 201a to move, the push rod 201a synchronously pushes the push plate 201b to move.

[0045] Specifically, the one-way toggle assembly 202 includes a toggle plate 202a arranged on one side of the pushing assembly 201, wherein the toggle plate 202a is a rectangular plate, a slider 202a-2 is installed on one side of the toggle plate 202a, a slide groove 202a-3 matching the slider 202a-2 is opened on the base, a plurality of ratchet teeth 202a-1 are provided on the surface of the toggle plate 202a, and a ratchet 202b is rotatably installed in the U-shaped groove under the bottom plate 101; wherein the toggle plate 202a and the ratchet 202b are symmetrically provided with two, and the ratchet teeth 202a-1 are unidirectionally meshed with the ratchet 202b.

[0046] Furthermore, the impact assembly 203 includes a traction structure 203a arranged on one side of the ratchet 202b, the traction structure 203a is connected to the ratchet 202b, and can drive the traction structure 203a to move while the ratchet 202b rotates, a fixing plate 203b is provided on one side of the traction structure 203a, the fixing plate 203b is fixedly installed under the base, a plurality of first wedge blocks 203c are slidably installed on the fixing plate 203b, a second wedge block 203d matching the first wedge block 203c is provided on one side of the first wedge block 203c, a guide seat 203e is provided on one side of the second wedge block 203d, and the guide seat 203e is connected to the fixing plate 203b. The fixed plate 203b is fixedly connected, and the second wedge block 203d is slidably connected to the guide seat 203e. When the first wedge block 203c moves due to the extrusion force, the first wedge block 203c matches the second wedge block 203d, so that the second wedge block 203d can move upward along the guide seat 203e, and push upward against the lower surface of the surface plate 103 to impact the surface plate 103, causing the surface plate 103 to vibrate and accelerate the falling of the slag on its surface. When the first wedge block 203c is separated from the second wedge block 203d, the second wedge block 203d slides and resets under the action of its own gravity, so that reciprocating impact work can be performed.

[0047] Furthermore, the traction structure 203a includes a traction rod 203a-1 arranged on one side surface of the ratchet 202b, wherein one end of the traction rod 203a-1 is rotatably connected to the one side surface of the ratchet 202b, and the other end of the traction rod 203a-1 is rotatably connected to a connecting shaft 203a-2, and one side of the connecting shaft 203a-2 is hinged with a connecting plate 203a-3; wherein the connecting shaft 203a-2 is arranged between two traction rods 203a-1, and a plurality of first wedge blocks 203c are connected to the connecting plate 203a-3. When the traction rod 203a-1 pulls the connecting shaft 203a-2 and the connecting plate 203a-3 to move, the first wedge block 203c can be driven to move synchronously, so that the first wedge block 203c can be driven to move forward and backward when the ratchet 202b rotates, and the first wedge block 203c can be used to squeeze the second wedge block 203d to move.

[0048] The rest of the structure is the same as that of Example 1.

[0049] Operation process: when the arc scraper 103b contacts the bottom end of the slag scoop, the buffer spring 105a is compressed, and the push rod 201a pushes the push plate 201b to move, and the push plate 201b pushes the toggle plate 202a to move below the ratchet 202b; when the arc scraper 103b is separated from the bottom end of the slag scoop to discharge the material, the spring can be used to push the surface plate 103 to move and reset, and at the same time promote the slag on the surface plate 103 to fall off. At this time, the buffer spring 105a pushes the arc scraper 103b to reset, and at the same time drives the toggle plate 202a to reset through the push rod 201a and the push plate 201b, and the ratchet 202a-1 on the toggle plate 202a meshes with the ratchet 202b, so that the ratchet 202b rotates. At this time, the ratchet 202b rotates and drives the traction rod 20 3a-1 moves, the traction rod 203a-1 can drive the first wedge block 203c to move forward or backward through the connecting shaft 203a-2 and the connecting plate 203a-3. When the first wedge block 203c is pushed forward, the first wedge block 203c can be used to push the second wedge block 203d to move up along the guide seat 203e and impact the lower surface of the surface plate 103, so that the surface plate 103 vibrates, thereby accelerating the falling of the slag accumulated on its surface; when the traction rod 203a-1 pulls the first wedge block 203c to reset, the second wedge block 203d slides and resets along the guide seat 203e under the action of its own gravity. In this way, reciprocating impact work can be performed to avoid slag adhering to the surface plate 103 and ensure a good slag scraping effect.

[0050] Example 3

[0051] Reference Figure 8 and Figure 9 As shown, this embodiment is different from the above embodiments in that it also includes a flipping mechanism 300, which includes a rotating shaft 301 arranged on both sides of the base plate 101 and connected to the extension plate 104, wherein the rotating shaft 301 is provided with a plurality of first hinges 301a and a plurality of second hinges 301b, one end of the first hinge 301a is fixedly connected to the side wall of the base plate 101, and one end of the second hinge 301b is fixedly connected to the extension plate 104, and one end of the rotating shaft 301 is connected to a rotating component 302, which is used to drive the rotating shaft 301 to rotate, thereby driving the extension plate 104 to flip.

[0052] Further, the rotating assembly 302 includes a rotating sleeve 302a provided at one end of the rotating shaft 301. The diameter of the rotating sleeve 302a is larger than that of the rotating shaft 301. A guiding groove 302b is formed in the rotating sleeve 302a. The guiding groove 302b is an arc-shaped groove, and the radian of the guiding groove 302b is the same as the maximum turning angle of the extension plate 104. A guiding rod 302c is fixedly connected to the bottom end of the surface layer plate 103. A limiting groove 302d matching the guiding rod 302c is formed in the bottom plate 101. When the surface layer plate 103 moves, the guiding rod 302c can be driven to move along the limiting groove 302d. One end of the guiding rod 302c extends into the guiding groove 302b, and the end of the guiding rod 302c extending into the guiding groove 302b is spherical. The movement of the surface layer plate 103 can be used to push the guiding rod 302c to move. When the guiding rod 302c moves along the guiding groove 302b, the rotating sleeve 302a can be driven to rotate. When the rotating sleeve 302a rotates, the rotating rod can be driven to rotate. When the rotating rod rotates, the extension plate 104 can be driven to turn over.

[0053] The remaining structures are the same as those in Embodiment 2.

[0054] Operation process: When the bottom end of the arc-shaped scraper 103b abuts against the bottom end of the slag scraper, the buffer spring 105a is compressed. At the same time, the surface layer plate 103 moves through the through groove 102a. When the surface layer plate 103 moves, the guiding rod 302c can be driven to move along the guiding groove 302b, and the rotating sleeve 302a can be driven to rotate. When the rotating sleeve 302a rotates, the rotating rod can be driven to rotate. When the rotating rod rotates, the extension plate 104 can be driven to turn over, so that the unfolded extension plate 104 can be turned over, and the included angle between the extension plate 104 and the surface layer plate 103 becomes smaller, which is convenient for intercepting the slag material and maximizing the scraping of the slag material.

[0055] During discharging, since the buffer spring 105a pushes the surface layer plate 103 to reset, the rotating sleeve 302a can be rotated reversely to reset, and the extension plate 104 can be slowly rotated and turned over to unfold, which is convenient for discharging the slag material and convenient for use.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
