Technical Field
[0001] This utility model relates to the field of workpiece processing technology, and in particular to an environmentally friendly shot blasting machine with dust removal function. Background Technology
[0002] An environmentally friendly shot blasting machine with dust removal function is a mechanical device used for cleaning and strengthening the surface of workpieces. It also has a highly efficient dust removal system to reduce dust emissions and achieve environmentally friendly operation. It mainly uses a shot blaster to propel shot at high speed onto the surface of the workpiece, using the impact force of the shot to remove impurities such as rust, oxide scale, and oil stains from the workpiece surface, so that the workpiece surface has a certain roughness and cleanliness, and improves the fatigue strength, corrosion resistance and other properties of the workpiece. However, traditional shot blasting machines have significant defects in the shot recycling process: on the one hand, the shot is easy to scatter in the corners or gaps of the cleaning chamber after the blasting operation, and there is a lack of efficient collection methods, resulting in a very low shot recovery rate. Enterprises need to frequently replenish shot, which greatly increases the cost of consumables. On the other hand, the shot that is not collected in time accumulates in the cleaning chamber and continues to impact the cleaning chamber walls, conveying devices and other key components, which increases the equipment failure rate and causes a lot of downtime maintenance costs.
[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: after the shot blasting machine cleans the workpiece, the scattered shot will accumulate randomly in the cleaning chamber, resulting in excessive wear of the internal parts of the cleaning chamber, increasing the frequency of equipment maintenance, and causing a large amount of shot waste, thus increasing production costs; therefore, in order to address the above problems, an environmentally friendly shot blasting machine with dust removal function is proposed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing shot blasting machines, where scattered shot accumulates randomly in the cleaning chamber after cleaning the workpiece, leading to excessive wear of internal components, increased equipment maintenance frequency, and significant waste of shot, thus increasing production costs. The invention proposes an environmentally friendly shot blasting machine with dust removal capabilities.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an environmentally friendly shot blasting machine with dust removal function, comprising a cleaning chamber, an operating table, and a dust collector. A shot blaster is installed on one side of the cleaning chamber, a hook is installed on the surface of the cleaning chamber, and a collection device is provided on the lower surface of the cleaning chamber. The collection device includes two square holes, both of which are opened on the lower surface of the cleaning chamber. Two fixed frames are fixedly connected to the lower surface of the cleaning chamber. A collection box is slidably connected to the inner wall of the fixed frames. A fixed plate is fixedly connected to the surface of the fixed frames, and a rod is slidably inserted into the fixed plate. A limiting plate is fixedly connected to the surface of the collection box, and an insertion hole is opened on the surface of the limiting plate. The inner wall of the insertion hole of the limiting plate is slidably connected to the rod, and a pull plate is fixedly connected to one end of the rod.
[0006] The effects achieved by the above-mentioned components are as follows: by setting up a collection device, the shot that has been blasted onto the surface of the workpiece can be collected and cleaned up, making it convenient to send the shot back to the shot blaster for reuse, thereby reducing production costs, avoiding waste of shot, greatly saving shot consumption, and preventing shot from piling up randomly in the cleaning chamber, which would lead to excessive wear of the internal components of the cleaning chamber and increase the frequency of equipment maintenance.
[0007] Preferably, the arc surface of the insertion rod is fitted with a spring, and the two ends of the spring are fixedly connected to the fixing plate and the pull plate, respectively.
[0008] The effect achieved by the above components is that, under the action of the spring, the insertion rod is automatically inserted into the insertion hole of the limiting plate and the insertion rod is firmly fixed in the insertion hole of the limiting plate, thereby improving the practicality of the device.
[0009] Preferably, the surface of the collection box is fixedly connected to two connecting plates, and a handle is fixedly connected to one side of the two connecting plates that are close to each other.
[0010] The above-mentioned components achieve the following effects: by setting up a handle, they provide operators with a stable and comfortable grip point, avoiding problems such as slippage or difficulty in applying force caused by direct contact with the surface of the collection box, reducing the difficulty of operation, and making the loading and unloading of the collection box more convenient and efficient.
[0011] Preferably, the inner wall of the fixing frame is rotatably connected with a plurality of round beads, and the arc surface of the round beads is slidably connected to the collection box.
[0012] The effect achieved by the above-mentioned components is that by setting the ball, the original surface contact sliding friction between the collection box and the fixed frame is transformed into rolling friction. The coefficient of rolling friction is much smaller than the coefficient of sliding friction, which makes the collection box slide more smoothly in the fixed frame and reduces labor intensity.
[0013] Preferably, the surface of the operating table is provided with a protective device, which includes two support plates. Both support plates are fixedly connected to the surface of the operating table. A rotating rod is fixedly connected to one side of the two support plates that are close to each other. A protective plate is rotatably connected to the arc surface of the rotating rod. A clamping plate is fixedly connected to one side of the protective plate. A circular hole is opened on the surface of the clamping plate. A square plate is fixedly connected to the surface of the operating table. A threaded rod is threaded into the square plate. The threaded rod is slidably connected to the inner wall of the circular hole of the clamping plate. A circular plate is fixedly connected to one end of the threaded rod.
[0014] The effect achieved by the above-mentioned components is as follows: by setting up protective devices, the buttons on the control panel are prevented from being accidentally touched by other people or objects after the operator has set the operating data, thus ensuring the stable operation of the shot blasting machine and avoiding the situation where the operating parameters of the shot blasting machine are arbitrarily changed due to accidental button touches, which could lead to abnormal shot blasting intensity, substandard workpiece processing quality, or even equipment failure and shutdown.
[0015] Preferably, the arc surface of the rotating rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the support plate and the protective plate, respectively.
[0016] The effect achieved by the above components is that, under the action of the torsion spring, the protective plate can be quickly and automatically rotated open and fixed at a certain angle, thus improving the convenience of the device.
[0017] Preferably, the surface of the circular plate is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly distributed on the circular plate in a circumferential array.
[0018] The effect achieved by the above-mentioned components is as follows: by setting anti-slip grooves, the friction between the circular plate and the operator's hand is increased. When the operator rotates the threaded rod to fix or open the protective plate, the fingers are embedded in the anti-slip grooves, which can provide a more stable grip and improve the stability of operation.
[0019] 1. In this utility model, by setting a collection device, the shot that has been blasted onto the surface of the workpiece can be collected and cleaned, making it convenient to send the shot back to the shot blaster for reuse. This reduces production costs, avoids the waste of shot, greatly saves shot consumption, and prevents shot from accumulating randomly in the cleaning chamber, which would lead to excessive wear of the internal parts of the cleaning chamber and increase the frequency of equipment maintenance.
[0020] 2. In this utility model, by setting a protective device, the buttons on the control panel are prevented from being accidentally touched by other people or objects after the operator has set the operating data. This ensures the stable operation of the shot blasting machine and avoids the situation where the operating parameters of the shot blasting machine are arbitrarily changed due to accidental button touch, which could lead to abnormal shot blasting intensity, substandard workpiece processing quality, or even equipment failure and shutdown.

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, this utility model provides a technical solution: an environmentally friendly shot blasting machine with dust removal function, including a cleaning chamber 1, an operating table 4, and a dust collector 5. A shot blaster 2 is installed on one side of the cleaning chamber 1, and a hook 3 is installed on the surface of the cleaning chamber 1. A collection device 6 is provided on the lower surface of the cleaning chamber 1. By setting the collection device 6, the shot that has been blasted onto the surface of the workpiece can be collected and cleaned, making it convenient to send the shot back to the shot blaster 2 for reuse. This reduces production costs, avoids waste of shot, greatly saves shot consumption, and prevents shot from accumulating randomly in the cleaning chamber 1, which could lead to excessive wear of the internal parts of the cleaning chamber 1 and increase the frequency of equipment maintenance. The surface of the operating table 4 is provided with a protective device 7. By setting the protective device 7, the buttons on the operating table 4 are prevented from being accidentally touched by other personnel or objects after the operator has set the operating data. This ensures the stable operation of the shot blasting machine and avoids the situation where the operating parameters of the shot blasting machine are arbitrarily changed due to accidental button touches, which could lead to abnormal shot blasting intensity, substandard workpiece processing quality, or even equipment failure and shutdown.
[0031] The following section will describe in detail the specific setup and function of its collection device 6 and protective device 7.
[0032] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in this embodiment: the collection device 6 includes two square holes 601, both of which are opened on the lower surface of the cleaning chamber 1. Two fixed brackets 602 are fixedly connected to the lower surface of the cleaning chamber 1. A collection box 603 is slidably connected to the inner wall of the fixed bracket 602. A fixed plate 605 is fixedly connected to the surface of the fixed bracket 602. A rod 606 is slidably inserted into the fixed plate 605. A limiting plate 604 is fixedly connected to the surface of the collection box 603. An insertion hole is opened on the surface of the limiting plate 604. The inner wall of the insertion hole of the limiting plate 604 is slidably connected to the rod 606. A pull plate 607 is fixedly connected to one end of the rod 606. A spring 608 is sleeved on the arc surface of the rod 606. The two ends of the spring 608 are fixedly connected to the fixed plate 605 and the pull plate 607, respectively. Under the action of the spring 608, the rod 606 is automatically inserted into the insertion hole of the limiting plate 604 and the rod 606 is firmly fixed in the limiting position. The effect of the insertion hole in plate 604 improves the practicality of the device. Two connecting plates 609 are fixedly connected to the surface of the collection box 603. A handle 610 is fixedly connected to the side of the two connecting plates 609 that are close to each other. By setting the handle 610, a stable and comfortable grip point is provided for the operator, avoiding slippage or difficulty in applying force caused by direct contact with the surface of the collection box 603. This reduces the difficulty of operation and makes the loading and unloading of the collection box 603 more convenient and efficient. Several round balls 611 are rotatably connected to the inner wall of the fixing frame 602. The arc surface of the round balls 611 is slidably connected to the collection box 603. By setting the round balls 611, the original surface contact sliding friction between the collection box 603 and the fixing frame 602 is transformed into rolling friction. The coefficient of rolling friction is much smaller than the coefficient of sliding friction, making the collection box 603 slide more smoothly in the fixing frame 602 and reducing labor intensity.
[0033] Reference Figure 6 , Figure 7 and Figure 8As shown, specifically, the protective device 7 includes two support plates 71, both of which are fixedly connected to the surface of the operating table 4. A rotating rod 72 is fixedly connected to one side of the two support plates 71 that is close to each other. A protective plate 73 is rotatably connected to the arc surface of the rotating rod 72. A clamping plate 75 is fixedly connected to one side of the protective plate 73. A circular hole is opened on the surface of the clamping plate 75. A square plate 76 is fixedly connected to the surface of the operating table 4. A threaded rod 77 is threaded into the square plate 76. The threaded rod 77 is slidably connected to the inner wall of the circular hole of the clamping plate 75. A circular plate 78 is fixedly connected to one end of the threaded rod 77. Two torsion springs 74 are sleeved on the arc surface of the rotating rod 72. The two ends of 74 are fixedly connected to the support plate 71 and the protective plate 73 respectively. Under the action of the torsion spring 74, the protective plate 73 can be quickly and automatically rotated open and fixed at a certain angle, which improves the convenience of the device. Several anti-slip grooves 79 are opened on the surface of the circular plate 78. The anti-slip grooves 79 are evenly distributed in a circumferential array on the circular plate 78. By setting the anti-slip grooves 79, the friction between the circular plate 78 and the operator's hand is increased. When the operator rotates the threaded rod 77 to fix or open the protective plate 73, the fingers are embedded in the anti-slip grooves 79, which can obtain a more stable grip and improve the stability of operation.
[0034] Working principle: When it is necessary to collect used projectiles, the projectiles that have been projected onto the workpiece surface will scatter at the bottom of the cleaning chamber 1. At this time, the two square holes 601 on the lower surface of the cleaning chamber 1 will function, allowing the projectiles to fall into the collection box 603 below through the square holes 601. When the collection box 603 is full of projectiles, the operator pulls the pull plate 607. The pull plate 607 drives the insertion rod 606 to overcome the elastic force of the spring 608 and slide within the fixing plate 605. Then, it is pulled out from the insertion hole of the limiting plate 604, releasing the fixation of the collection box 603. Then, by holding the handle 610, the collection box 603 can be smoothly pulled out along the fixing frame 602 for projectile cleaning and transfer. The handle 610 provides the operator with a comfortable and stable grip point, making it easy to apply force when loading and unloading the collection box 603, reducing the difficulty of operation and labor intensity. At this time, the ball 611 rotatably connected to the inner wall of the fixing frame 602 interacts with the collection box 603. When the bottom surfaces come into contact, rotation occurs, transforming the sliding friction between the collection box 603 and the fixed frame 602 into rolling friction. This allows the collection box 603 to slide more smoothly within the fixed frame 602. After cleaning, the collection box 603 is pushed back into the fixed frame 602, and the pull plate 607 is released. The elastic restoring force of the spring 608 pushes the pull plate 607 and the insertion rod 606, causing the insertion rod 606 to automatically insert into the insertion hole of the limiting plate 604, firmly fixing the collection box 603 for the next round of shot collection. By setting up the collection device 6, the shot that has been blasted onto the workpiece surface can be collected and cleaned, making it convenient to return the shot to the shot blaster 2 for reuse. This reduces production costs, avoids shot waste, greatly saves shot consumption, and prevents shot from accumulating randomly in the cleaning chamber 1, which could lead to excessive wear of the internal components of the cleaning chamber 1 and increase the frequency of equipment maintenance.
[0035] Working principle: When the protective device 7 is needed to prevent accidental touches on the operating table 4, the protective plate 73 is moved, causing it to rotate around the rotating rod 72 until it completely blocks the buttons on the operating table 4. At this time, the torsion spring 74 stores the elastic potential energy under torsion. The round hole on the retaining plate 75 on one side of the protective plate 73 is aligned with the position of the square plate 76 on the surface of the operating table 4. The round plate 78 is then rotated. Because the surface of the round plate 78 has anti-slip grooves 79, the friction between the hand and the round plate 78 is increased, allowing the operator to apply force more stably and effortlessly. The round plate 78 drives the threaded rod 77 to rotate threadedly inside the square plate 76. The threaded rod 77 passes through the round hole of the retaining plate 75. As the threaded rod 77 continues to screw in, it gradually presses the retaining plate 75 tightly onto the square plate 76, thereby firmly fixing the protective plate 73 to the surface of the operating table 4, completing the protection of the operating table 4. When the operator needs to set parameters or start the equipment on the control panel 4, and needs to open the protective device 7, the operator rotates the circular plate 78 again. The circular plate 78 drives the threaded rod 77 to rotate within the square plate 76, rotating out of the circular hole in the clamping plate 75, releasing the fixation on the protective plate 73. At this time, the torsion spring 74 releases its torsional elastic potential energy, thereby driving the protective plate 73 to rotate on the arc surface of the rotating rod 72 and fix it at a certain angle, completing the self-opening of the protective plate 73. By setting the protective device 7, the operator can prevent the buttons on the control panel 4 from being accidentally touched by other personnel or objects after setting the operating data, ensuring the stable operation of the shot blasting machine and avoiding the situation where the operating parameters of the shot blasting machine are arbitrarily changed due to accidental button touches, which could lead to abnormal shot blasting intensity, substandard workpiece processing quality, or even equipment failure and shutdown.
