Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for vertical shot blasting machines, and in particular to a feeding system for vertical shot blasting machines. Background Technology

[0002] Vertical shot blasting machines are used for parabolic treatment of metal workpieces. Specifically, they use steel balls to strike the workpiece, causing oxides on its surface to peel off. For larger workpieces, large shot blasting machines, typically vertical in structure, are used. The feed inlet of a vertical shot blasting machine is usually set high, and a tilting hopper structure is often incorporated. When feed is needed, steel balls are dropped into the hopper at a lower position, and then the hopper is tilted to guide the balls into the feed inlet. However, in actual operation, this feeding method is often only suitable for small batches. Larger vertical shot blasting machines are not suitable (steel balls are heavy, and larger machines often have higher feed inlets, making the tilting hopper structure more energy-intensive and dangerous). Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a vertical shot blasting machine feeding system, which solves the problem that the feeding structure of the existing technology is not suitable for larger vertical shot blasting machines.

[0004] According to an embodiment of the present invention, a feeding system for a vertical shot blasting machine includes a mounting frame disposed next to the vertical shot blasting machine. A trolley that moves laterally reciprocating is disposed on the top of the mounting frame. The trolley is connected to a chain elevator, and the elevator includes a base frame and a support plate that rotates relative to the base frame. The mounting frame is also connected to a guide chute, which is inclined and extends to the feeding port of the vertical shot blasting machine at its lower end. The system also includes a track fixed relative to the mounting frame and a feeding trolley that moves on the track. The feeding trolley can move along the track to the support plate when it is at its lowest position. The mounting frame can be at a height comparable to the vertical shot blasting machine. During the reciprocating motion of the trolley, it moves closer to or further away from the machine, simultaneously moving the base frame and pallet closer to or further away. When feeding is required, steel balls are loaded into the feeding trolley. The trolley moves onto the pallet, and the chain elevator lifts the pallet, base frame, and feeding trolley upwards. The trolley then moves closer to the vertical shot blasting machine, with the feeding trolley positioned near the higher end of the guide chute. The pallet then rotates, causing the feeding trolley to tilt and discharge the steel balls. After passing through the guide chute, the steel balls enter the feeding port, thus achieving feeding. This design can meet the needs of larger feeding volumes and is suitable for larger vertical shot blasting machines, solving the problem that the feeding structure in existing technologies is unsuitable for larger vertical shot blasting machines.

[0005] Furthermore, the trolley is fixedly connected to a pair of guide columns located within the mounting frame, and the bottom frame is vertically slidably connected to the two guide columns. The chain hoist includes an electric hoist mounted on the trolley, the electric hoist is connected to a lifting chain, and the lifting chain is also connected to a top frame located above the pallet. The top frame and the bottom frame are fixed together by a first connecting frame.

[0006] Furthermore, the two guide columns are fixedly connected to the crane via a second connecting frame.

[0007] Furthermore, a pair of rotating seats are fixedly connected to the bottom frame, and one end of the support plate is rotatably connected to the two rotating seats through a pair of mounting shafts.

[0008] Furthermore, a winch and a pulley are fixedly connected to the top frame, and a connecting lug is fixedly connected to the end of the support plate away from the mounting shaft. The winch is connected to a pull rope, which is fixed to the connecting lug after passing through the pulley.

[0009] Furthermore, a positioning ring is fixedly connected to one end of the pallet with a connecting ear. The positioning ring is positioned close to the track and offset from the feeding trolley. The feeding trolley is also fixedly connected to an alignment ring that can align with the positioning ring. The positioning ring and the alignment ring can be fixed by a pin.

[0010] Furthermore, a receiving trough is also provided below the guide trough.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By using a traveling crane and a chain elevator, the pallet and base frame can be moved closer to or further away from the vertical shot blasting machine. When feeding is needed, steel balls are loaded into the feeding trolley. The feeding trolley moves to the pallet, and the chain elevator lifts the pallet, base frame, and feeding trolley upwards. The traveling crane moves closer to the vertical shot blasting machine, and the feeding trolley approaches the higher end of the guide chute. Then, the pallet rotates, causing the feeding trolley to tilt and discharge the steel balls. After passing through the guide chute, the steel balls enter the feeding port, thus achieving feeding. This can meet the feeding needs of larger quantities and is suitable for larger vertical shot blasting machines, solving the problem that the feeding structure in the existing technology is not suitable for larger vertical shot blasting machines.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] In an exemplary implementation, such as Figure 1 , 2 As shown, this embodiment provides a feeding system for a vertical shot blasting machine, which includes a mounting frame 2 installed next to the vertical shot blasting machine 1. A trolley 3 that moves laterally reciprocating is installed on the top of the mounting frame 2. The trolley 3 is connected to a chain elevator, which includes a base frame 4 and a support plate 5 that rotates relative to the base frame 4. The mounting frame 2 can be positioned at a height equivalent to or at least higher than the feeding port 6 of the vertical shot blasting machine 1. The chain elevator allows the base frame 4 and the support plate 5 to be positioned above the feeding port 6. The mounting frame 2 is also connected to a guide chute 7, which is inclined and extends at its lower end into the feeding port 6 of the vertical shot blasting machine 1. The feeding system also includes a track 8 fixed relative to the mounting frame 2. The system includes a feeding trolley 9 that moves along track 8. The feeding trolley 9 can move along track 8 to the pallet 5 at its lowest position. When feeding is required, steel balls are loaded into the feeding trolley 9. The feeding trolley 9 moves onto the pallet 5, and the chain elevator lifts the pallet 5, the bottom frame 4, and the feeding trolley 9. The traveling trolley 3 moves closer to the vertical shot blasting machine 1, and the feeding trolley 9 approaches the higher end of the guide chute 7. Then, the pallet 5 rotates, causing the feeding trolley 9 to tilt and discharge the steel balls. After passing through the guide chute 7, the steel balls enter the feeding port 6 to achieve feeding. This can meet the feeding needs of a larger quantity and is suitable for larger vertical shot blasting machines 1, solving the problem that the feeding structure in the prior art is not suitable for larger vertical shot blasting machines 1.

[0020] In a more detailed scheme, a pair of rotating seats 18 are fixedly connected to the bottom frame 4. One end of the pallet 5 is rotatably connected to the two rotating seats 18 through a pair of mounting shafts 19. The two rotating seats 18 and the mounting shafts 19 cooperate to realize the relative rotation of the pallet 5 and the bottom frame 4. At the same time, the end of the pallet 5 away from the two rotating seats 18 can rest on the bottom frame 4, so that the pallet 5 can be stably above the bottom frame 4. Also, when the bottom frame 4 and the pallet 5 are in the lowest position, there is a small gap between the pallet 5 and the track 8, which facilitates the feeding trolley 9 to transition from the track 8 to the pallet 5.

[0021] In a further embodiment, the gantry crane 3 is fixedly connected to a pair of guide columns 10 located within the mounting frame 2. The bottom frame 4 is vertically slidably connected to the two guide columns 10. The chain hoist includes an electric hoist 11 mounted on the gantry crane 3. The electric hoist 11 is connected to a lifting chain 12, which is also connected to a top frame 13 located above the pallet 5. The top frame 13 and the bottom frame 4 are fixed together by a first connecting frame 14. The first connecting frame 14 can be a pair, and the feeding trolley 9 is located between the two first connecting frames 14. The gantry crane 3 and the two guide columns 10 can also be installed using two similar second connecting frames 15. The guide columns 10 allow the bottom frame 4 to move up and down more stably under the sliding guidance of the guide columns 10. When the crane 3 moves laterally, it can maintain lateral stability without swaying, thus ensuring the smooth movement of the feeding trolley 9. More specifically, a winch 16 and a pulley 17 are fixedly connected to the top frame 13. A connecting ear 20 is also fixedly connected to the end of the pallet 5 away from the mounting shaft 19. The winch 16 is connected to a pull rope 21, and the pull rope 21 is fixed to the connecting ear 20 after passing through the pulley 17. The winch 16 can pull the pull rope 21, thereby lifting one end of the pallet 5 to achieve rotation. In particular, the pull rope 21, the winch 16, the pulley 17, and the connecting ear 20 can all be located on opposite sides of the feeding trolley 9 to provide a smooth pulling effect. The winch 16 can unwind the pull rope 21 to return the pallet 5 to its initial state.

[0022] More specifically, one end of the pallet 5 with the connecting ear 20 is also fixedly connected to a positioning ring 22, and the positioning ring 22 is positioned close to the track 8 and offset from the feeding trolley 9. The feeding trolley 9 is also fixedly connected to an alignment ring 23 that can align with the positioning ring 22, via a pin 25 (in Figure 1 , 2The central pin 25 is detachably connected to the feeding trolley 9. It can be removed when the positioning ring 22 and the alignment ring 23 need to be fixed, and then the positioning ring 22 and the alignment ring 23 can be connected to fix the positioning ring 22 and the alignment ring 23. This allows the feeding trolley 9 to be relatively fixed on the pallet 5, thereby ensuring that the feeding trolley 9 rotates synchronously when the pallet 5 rotates, pouring the steel balls into the guide trough 7. Furthermore, a receiving trough 24 is also provided below the guide trough 7. Some steel balls that accidentally jump out of the guide trough 7 can fall into the receiving trough 24, preventing the steel balls from rolling to other positions and making them inconvenient to collect.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
