Technical Field

[0001] The utility model relates to the field of material returning of shot blasting machines, in particular to a material returning mechanism of a crawler type shot blasting machine. Background Art

[0002] Shot blasting machine is a mechanical device that uses high-speed projectiles thrown by the shot blasting machine to clean or strengthen the surface of the workpiece. The workpiece is sent into the shot blasting room through the conveyor mechanism. The shot blasting machine in the shot blasting room blasts the workpiece to remove the oxide scale on the surface of the workpiece. Figure 2 The shot blasting machine shown includes brackets on the front and rear sides, a conveyor belt is provided between the brackets, a shot blasting chamber is installed above the bracket in the middle of the conveyor belt, and the two ends of the shot blasting chamber are provided with a feed port and a discharge port on the right and left sides respectively, and the feed port and the discharge port of the shot blasting chamber are installed with blocking curtains.

However, in practice, workpieces passing through the shot blasting chamber may not meet the required quality standards, necessitating rework and secondary shot blasting. Currently, workpieces are typically recycled after reaching the end of a conveyor belt, which is cumbersome. There is no workpiece return mechanism located at the shot blasting chamber outlet to shorten rework time. Summary of the Invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0033] like Figures 1 to 5The figure shows a return mechanism for a crawler-type shot blasting machine, comprising front and rear brackets 1, a conveyor belt 2 disposed between the brackets 1, a shot blasting chamber 3 mounted above the bracket in the middle of the conveyor belt 2, and a feed inlet and a discharge outlet (not separately labeled) disposed at the right and left ends of the shot blasting chamber 3, respectively. Sealing curtains 31 are mounted on the feed inlet and the discharge outlet, and the upper surface of the conveyor belt 2 is flush with the upper surface of the bracket 1. A U-shaped bracket 4 with an upper opening is fixed to the bracket 1 in front of the conveyor belt 2 on the left side of the discharge outlet of the shot blasting chamber 3. A forward- and backward-flipping discharge mechanism 5 is mounted within the U-shaped bracket 4 (normally in a vertical position, flipped back and laid flat when in use). The unloading mechanism 5 includes a first baffle 51 in the front-to-back direction. The front end of the first baffle 51 is disposed in the U-shaped bracket 4. Bolts 41 are provided on the left and right sides of the U-shaped bracket 4, and the protruding ends of the bolts 41 are provided with locking nuts (not separately marked) for clamping the first baffle 51. The rear end of the first baffle 51 extends to the upper side of the rear bracket 1 and bends to the right to form a second baffle 52. A first handle 521 is provided at the center of the rear side of the second baffle 52. A third baffle 54 is provided in the middle of the right side of the first baffle 51, tilted downward to the right. A support plate 56 is fixed to the bottom of the area enclosed by the first, second, and third baffles 51, 52, and 54. A return structure 6 is fixed to the front side of the front bracket 1, with the left side higher and the right side lower.

[0034] The vertical section of the first baffle 51 is a vertical rectangle, and the left side of the first baffle 51 is in contact with the left and right sides of the U-shaped bracket 4. This facilitates the bolt 41 and the lock nut to clamp the first baffle 51, and helps the blanking mechanism 5 to maintain a vertical fixed state.

[0035] A shielding portion 53 inclined forward is provided at the right end portion of the second baffle 52 .

[0036] The return material structure 6 includes a bottom plate 61 that is higher on the left and lower on the right. Blocks 62 are fixed on the front, rear and left sides of the upper surface of the bottom plate 61 respectively. A notch 63 is provided at the left end of the rear block 62 for cooperating with the unloading mechanism 5. The rear side surface of the bottom plate 61 is fixedly connected to the front side surface of the front bracket 1. A storage box 7 with an upper opening is split on the right side of the right end of the bottom plate 61.

[0037] Vertical supports 64 are fixedly provided on the bottom surfaces of the left and right ends of the bottom plate 61 .

[0038] The upper opening of the storage box 7 is flush with the bottom surface of the right end portion of the bottom plate 61. The storage box 7 is in the shape of a rectangular parallelepiped, and a second handle 71 is fixedly provided on the front and rear outer sides respectively.

[0039] A wedge-shaped plate 561 for guiding the workpiece is fixed to the right side of the support plate 56 .

[0040] A rubber pad 11 is bonded and fixed to the bracket 1 on the right side of the U-shaped bracket 4, and the front end of the rubber pad 11 extends downward to the upper surface of the bottom plate 61. The rubber pad 11 plays a protective role on the bracket upper surface and the rear side block.

[0041] During use, if the workpiece exiting the discharge port is found to be unqualified, the unloading mechanism 5 is quickly flipped backward and laid flat on the bracket 1. The workpiece can then slide onto the right end of the support plate 56 (the wedge plate 561 guides the workpiece). The workpiece can then be pulled upward using the first handle 521 on the rear side. This raises the rear end of the support plate 56, allowing the workpiece to slide forward under gravity, thus unloading the workpiece. If there are a large number of workpieces, the machine can be stopped in batches for unloading (the conveyor belt 2 stops unloading once the support plate 56 is full). The triangular area 55 formed between the third baffle 54 and the first baffle 51 guides the workpiece to the right, preventing the U-shaped bracket 4 from blocking the workpiece from falling. The shielding portion 53 shields and gathers the workpiece, preventing it from sliding outward. Workpieces that slide down from the front slide through the notch 63 onto the bottom plate 61 and then slide into the storage box 7 under the action of gravity, thereby improving overall rework efficiency. Example 2

[0042] like Figure 6 、 Figure 7 As shown, the unloading mechanism 5 is detachably provided with a shielding structure 57 (not normally installed on the supporting plate 56 and only installed when the supporting plate 56 is raised for unloading) for preventing the workpiece from sliding to the right.

[0043] The shielding structure 57 includes a fourth baffle 571 on the right side of the support plate 56, and a vertical first plug rod 572 is fixed to the front and rear ends of the bottom of the fourth baffle 571 respectively, and the front and rear ends of the right end of the support plate 56 are embedded with a first blind hole 562 that is in damping and sliding cooperation with the first plug rod 572. A fixing plate 573 is fixed to the left of the center position of the upper end on the left side surface of the fourth baffle 571, and a vertical second plug rod 574 is fixed to the bottom surface of the left end of the fixing plate 573. A second blind hole 511 that is in damping and sliding cooperation with the second plug rod 574 is embedded on the upper surface of the first baffle 51.

[0044] During use, after the workpiece slides onto the support plate 56, the shielding structure 57 is installed to block the workpiece on the right side to prevent it from sliding to the right during unloading.
