Abstract
Description
Technical Field
[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a shot blasting recovery mechanism for a shot blasting machine. Background Technology
[0002] Shot blasting machines are widely used in casting cleaning, forging descaling, and steel pretreatment. They primarily use a high-speed rotating shot blaster to propel abrasive materials such as steel shot onto the workpiece surface to clean, strengthen, or alter its surface condition. During the operation of shot blasting machines, the recovery and reuse of the blasted shot is crucial for improving equipment efficiency and reducing costs. As a key component of the shot blasting machine, the performance of the shot blasting recovery mechanism has a decisive impact on the overall effectiveness and operational economy of the machine.
[0003] Especially in the core process of shot blasting recovery, existing shot blasting machine waste recovery mechanisms, such as those disclosed in utility model patent CN 216371738 U, although involving the field of casting cleaning and realizing the basic function of steel shot recovery, have gradually exposed a series of obvious limitations and technical problems in practical applications. The recovery mechanism in this patent includes a working box, a mounting slot, a shot blasting assembly, a recovery box, and a drive assembly, realizing the recovery of steel shot through a series of mechanical structures.
[0004] Specifically, existing shot blasting recovery systems face the significant problem of inconvenient screening of broken shot during the recovery process. Used steel shot often contains broken shot, and the recovery structure described in the patent can only achieve basic steel shot recovery, failing to effectively screen the broken shot during the recovery process. This results in inconsistent quality of the recovered steel shot, requiring additional manual sorting to separate the broken shot, which not only increases operational complexity but also reduces recovery efficiency.
[0005] Therefore, to address the shortcomings of existing technologies, we urgently need a shot blasting recovery mechanism for shot blasting machines to solve these problems. This new shot blasting recovery mechanism should be able to effectively screen broken shot fragments during the recovery process, improve the quality of recovered steel shot, increase recovery efficiency, reduce operational complexity, and provide strong support for the continuous and efficient operation of shot blasting machines. Utility Model Content
[0006] The purpose of this invention is to provide a shot blasting recovery mechanism for a shot blasting machine, which solves the problem of inconvenient screening of broken shot during the recovery operation of existing shot blasting recovery mechanisms.
[0007] To achieve the above objectives, this utility model provides a shot blasting machine shot blasting recovery mechanism, including a recovery chamber and a top cover connected to the top of the recovery chamber;
[0008] The bottom side of the recycling bin has a connection port, and a waste collection bin is set inside the connection port;
[0009] The recycling bin is equipped with a V-shaped screening frame inside. The side wall of the V-shaped screening frame has several screening slots. The inner wall of the recycling bin is connected to a supporting frame. The edge of the V-shaped screening frame is connected to the top of the supporting frame through an elastic connection structure.
[0010] A vibration motor is connected to one side of the V-shaped screening frame, and a feed inlet is provided on the top of the top cover.
[0011] The top of the top cover is connected to a telescopic connecting cover adapted to the feed inlet, and the bottom end of the telescopic connecting cover extends to the top of the V-shaped screening frame.
[0012] The outer wall of the supporting frame is bolted to the inner wall of the recycling bin. Several cylinders are fixedly connected to the four bottom corners of the supporting frame, and circular holes communicating with the inside of the cylinders are opened at the four top corners of the supporting frame.
[0013] The waste collection bin has a U-shaped tie rod on one side, and one end of each of the two vertical sections of the tie rod is bolted to the side wall of the waste collection bin.
[0014] Each cylinder has a vibration spring connected to the bottom of its inner cavity, and the outer ring of the V-shaped screening frame is connected to a connecting frame. At the four corners of the bottom of the connecting frame, a round rod that is adapted to slide and connect with the round hole is fixedly connected.
[0015] The top two sides of the connecting frame are fixedly connected to handles, and the bottom of the connecting frame is in contact with the top of the supporting frame.
[0016] This invention relates to a shot blasting machine's shot blasting recovery mechanism. Through the design of a V-shaped screening frame and screening trough, and the drive of a vibrating motor, it achieves effective screening of broken shot during the recovery process. This solves the problem in existing technologies where broken shot is mixed with whole steel shot, requiring additional manual sorting, and greatly improves the quality of the recovered steel shot. Since the screening process is completed automatically under the action of mechanical vibration, it significantly improves recovery efficiency compared to manual sorting. This not only saves labor costs but also shortens the recovery cycle, allowing the shot blasting machine to be put into the next round of work more quickly. Attached Figure Description

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0025] Example 1
[0026] Please see Figure 1-5 As shown, a shot blasting machine shot blasting recovery mechanism of this embodiment includes a recovery chamber 2 and a top cover 3 connected to the top of the recovery chamber 2; a connection port 7 is provided at the bottom of one side of the recovery chamber 2, and a waste collection chamber 1 is provided inside the connection port 7; a V-shaped screening frame 5 is provided inside the recovery chamber 2, and a plurality of screening grooves 12 are provided on the side wall of the V-shaped screening frame 5; a supporting frame 14 is connected to the inner wall of the recovery chamber 2, and the edge of the V-shaped screening frame 5 is connected to the top of the supporting frame 14 through an elastic connection structure; a vibration motor 8 is connected to one side of the V-shaped screening frame 5, and a feed port is provided at the top of the top cover 3.
[0027] First, the mixture of used steel shot and fragmented shot enters the recovery chamber 2 through the feed inlet at the top of the top cover 3. This mixture then falls onto the V-shaped screening frame 5, which is designed to effectively disperse and hold the abrasive particles. The sidewalls of the V-shaped screening frame 5 have several screening grooves 12, the size and shape of which are carefully designed to allow smaller fragmented shot to pass through while retaining larger, intact steel shot.
[0028] Next, the vibrating motor 8 starts, generating vibrational force that is transmitted to the V-shaped screening frame 5. Because the edges of the V-shaped screening frame 5 are connected to the top of the supporting frame 14 via an elastic connection structure, this design allows the V-shaped screening frame 5 to effectively vibrate up and down under the drive of the vibrating motor 8, thereby accelerating the screening process. Under the action of vibration, the crushed pellets fall through the screening trough 12 to the bottom of the recovery bin 2, and finally enter the waste collection bin 1 through the connection port 7 for collection.
[0029] Meanwhile, the larger, intact steel shot remains on the V-shaped screening frame 5, which can be removed later to recycle the intact steel shot.
[0030] Example 2
[0031] Please see Figure 1-5 As shown in this embodiment, a shot blasting machine's shot blasting recovery mechanism has a telescopic connecting cover 4 adapted to the feed inlet connected to the top of the top cover 3. The bottom end of the telescopic connecting cover 4 extends to the top of the V-shaped screening frame 5. Specifically, when the mixture of used steel shot and crushed shot enters through the feed inlet at the top of the top cover 3, the telescopic connecting cover 4, as an extension of the feed inlet, extends its bottom end to the top of the V-shaped screening frame 5. In this way, before the mixture falls into the V-shaped screening frame 5, it is guided by the telescopic connecting cover 4, ensuring that the abrasive can fall accurately and evenly onto the V-shaped screening frame 5. The design of the telescopic connecting cover 4 effectively avoids the splashing and scattering of abrasive during the feeding process due to excessive drop or directional deviation, improving the utilization rate and recovery efficiency of the abrasive, while maintaining a clean working environment.
[0032] A U-shaped pull rod 6 is installed on one side of the waste collection bin 1. One end of each of the two vertical sections of the pull rod 6 is bolted to the side wall of the waste collection bin 1. Specifically, when the waste pellets in the waste collection bin 1 accumulate to a certain amount, the operator can easily remove the waste collection bin 1 from the connection port 7 for cleaning by pulling the U-shaped pull rod 6. The design of the U-shaped pull rod 6 makes the removal and installation of the waste collection bin 1 simpler and faster, improving the operator's work efficiency and facilitating subsequent waste disposal.
[0033] Example 3
[0034] Please see Figure 1-5As shown in this embodiment, a shot blasting machine's shot blasting recovery mechanism has a supporting frame 14 whose outer wall is bolted to the inner wall of the recovery chamber 2. Several cylinders 16 are fixedly connected to the four bottom corners of the supporting frame 14, and circular holes 15 communicating with the interior of the cylinders 16 are opened at the four top corners of the supporting frame 14. Specifically, the supporting frame 14 is bolted to the inner wall of the recovery chamber 2, providing stable support for the V-shaped screening frame 5. Simultaneously, the fixed connection of several cylinders 16 at the four bottom corners of the supporting frame 14 and the circular holes 15 communicating with the interior of the cylinders 16 at the four top corners provide space for the vibration of the V-shaped screening frame 5. This structural design allows the V-shaped screening frame 5 to vibrate freely under the drive of the vibration motor 8 without being hindered by direct contact with the inner wall of the recovery chamber 2. Furthermore, the cooperation of the cylinders 16 and the circular holes 15 facilitates the installation and disassembly of the V-shaped screening frame 5.
[0035] Each cylinder 16 has a vibration spring 13 connected to its inner bottom. The outer ring of the V-shaped screening frame 5 is connected to a connecting frame 10. At the four corners of the bottom of the connecting frame 10, round rods 9, adapted to and slidably connected to the round holes 15, are fixedly connected. Specifically, driven by the vibration motor 8, the V-shaped screening frame 5 is connected to the supporting frame 14 via the connecting frame 10 and the round rods 9, while the vibration spring 13 provides additional elastic support. This structure allows the V-shaped screening frame 5 to screen more stably and effectively during vibration. The addition of the vibration spring 13 enhances the vibration effect of the V-shaped screening frame 5 and improves screening efficiency. Simultaneously, the cooperation between the connecting frame 10 and the round rods 9 ensures the stability of the V-shaped screening frame 5 during vibration.
[0036] Handles 11 are fixedly connected to both sides of the top of the connecting frame 10. The bottom of the connecting frame 10 contacts the top of the supporting frame 14. Specifically, when the V-shaped screening frame 5 needs to be cleaned or replaced, the operator can easily lift and remove the V-shaped screening frame 5 from the supporting frame 14 by holding the handles 11. The design of the handles 11 makes the removal and installation of the V-shaped screening frame 5 easier and less strenuous, improving the convenience and work efficiency of the operator. At the same time, the handles 11 also serve as an auxiliary support point for the V-shaped screening frame 5, enhancing its stability during use.
[0037] This solution includes the following work process:
[0038] First, the mixture of used steel shot and fragmented shot enters the recovery chamber 2 through the feed inlet at the top of the top cover 3. During this process, the telescopic connecting hood 4 extends from the feed inlet to the top of the V-shaped screening frame 5. Before falling into the V-shaped screening frame 5, the mixture is guided by the telescopic connecting hood 4, ensuring that the abrasive particles fall accurately and evenly onto the V-shaped screening frame 5. The V-shaped screening frame 5 is designed to effectively disperse and hold the abrasive particles; the size and shape of the several screening slots 12 on its sidewalls are carefully designed to allow smaller fragmented shot to pass through while retaining larger, intact steel shot.
[0039] Next, the vibrating motor 8 starts, generating vibrational force that is transmitted to the V-shaped screening frame 5. The edges of the V-shaped screening frame 5 are connected to the top of the supporting frame 14 via an elastic connection structure. The supporting frame 14 is bolted to the inner wall of the recovery bin 2, providing stable support for the V-shaped screening frame 5. Simultaneously, several cylinders 16 are fixedly connected to the four bottom corners of the supporting frame 14, and circular holes 15 communicating with the interior of the cylinders 16 are opened at the four top corners, providing space for the vibration of the V-shaped screening frame 5. Driven by the vibrating motor 8, the V-shaped screening frame 5 is connected to the supporting frame 14 via the connecting frame 10 and the circular rod 9. A vibration spring 13 connected to the bottom of the inner cavity of each cylinder 16 provides additional elastic support. This structure allows the V-shaped screening frame 5 to perform screening more stably and effectively during vibration.
[0040] Under the action of vibration, the fragmented bullets fall through the screening trough 12 to the bottom of the recycling bin 2, and finally enter the waste collection bin 1 through the connection port 7 for collection. When the fragmented bullets in the waste collection bin 1 accumulate to a certain amount, the operator can easily remove the waste collection bin 1 from the connection port 7 for cleaning by pulling the U-shaped lever 6.
[0041] Meanwhile, larger, intact steel shot remains on the V-shaped screening frame 5. When the V-shaped screening frame 5 needs to be cleaned or replaced, the operator can easily lift and remove it from the supporting frame 14 by holding the handle 11 to recycle the intact steel shot.
[0042] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
