Description
Technical Field
[0001] This utility model relates to the field of sandblasting technology, specifically to a portable multi-functional sandblasting gun. Background Technology
[0002] In the daily maintenance and upkeep of oil equipment, surface cleaning, rust removal, and polishing are crucial processes. Oil equipment is exposed to harsh environments for extended periods, making it susceptible to corrosion, oil stains, and rust. This not only affects the equipment's appearance but can also reduce its lifespan and operational efficiency. Therefore, regular surface cleaning and treatment of oil equipment is essential for ensuring its normal operation. Traditional sandblasting equipment is primarily used for surface cleaning and rust removal, but its function is relatively limited, typically only allowing the use of one type of abrasive. However, in practical applications, different surface treatment needs may require the use of different types or particle sizes of abrasive. For example, heavy rust requires the use of high-hardness steel grit, while fine polishing necessitates the use of finer-grained glass beads or ceramic abrasive. In addition, in certain special cases, it may be necessary to mix multiple types of sand to achieve better treatment results. However, existing sandblasting equipment usually does not have the function of classifying, storing and mixing sand. Operators need to manually change or mix the sand, which not only increases the complexity of the operation but also reduces work efficiency. Furthermore, traditional sandblasting equipment is bulky and difficult to use in the field or in confined spaces, which limits its application in oil equipment maintenance. Therefore, there is an urgent need for a portable multi-functional sandblasting gun. Utility Model Content

A connecting band 20 is fixedly installed on the connecting ring 19, and one end of the connecting band 20 is fixedly installed on the upper part of the sand storage tank 2. Through the cooperation of the connecting band 20 and the connecting ring 19, the connection between the threaded cover 8 and the gun body 1 can be realized, so as to prevent the threaded cover 8 from falling off and being lost after being unscrewed from the threaded feed port 7.
[0032] A horizontal partition 9 is fixedly installed inside the sand storage tank 2. Several vertical partitions 5 are fixedly installed on the upper part of the horizontal partition 9.

A guide plate 18 is provided on the upper part of the horizontal partition 9 outside the port 11. The guide plate 18 can provide a flow guide for the sand in the sand storage chamber 6 to the port 11, so as to avoid the sand remaining in the sand storage chamber 6.
[0033] Motor 13 is fixedly installed on the right side wall of sand storage tank 2, and sand mixing mechanism 14 connected to motor 13 is provided in sand mixing chamber 10;
[0034] The sand control mechanism 12 includes:
[0035] A baffle plate 12-1 is provided in the opening 11. A control rod 12-2 is fixedly inserted through the baffle plate 12-1. The rear end of the control rod 12-2 is rotatably connected to the transverse partition 9 through a bearing.

The rotation of -4 and polygonal plate 12-3 can cause control rod 12-2 to drive baffle plate 12-1 to flip, thereby controlling the falling of sand in sand storage chamber 6 into sand mixing chamber 10. The observation port on the front side wall of sand storage chamber 6 is equipped with observation window 21, and the observation window 21 is equipped with scale line 22. Through the cooperation of observation window 21 and scale line 22, it is easy for staff to understand the remaining amount of sand in sand storage chamber 6, thereby making it easier for staff to judge the mixing ratio of each sand in sand mixing chamber 10.
[0037] The sand mixing mechanism 14 includes:
[0038] Rotating rod 14-1 is rotatably inserted into the right side wall of the sand mixing chamber 10 via bearings, and the output shaft of motor 13 is fixedly connected to rotating rod 14-1;
[0039] A fixed cylinder 14-2 is fixedly installed on the left side wall of the sand mixing chamber 10. A stirring shaft 14-3 is suspended inside the sand mixing chamber 10. The left and right ends of the stirring shaft 14-3 are respectively movably inserted into the fixed cylinder 14-2 and the rotating rod 14-1. A reciprocating guide groove 16 is opened on the inner wall of the fixed cylinder 14-2. Two guide blocks 14-4 are movably installed in the reciprocating guide groove 16, and the two guide blocks 14-4 are fixedly installed on the stirring shaft 14-3.
[0040] The movable strips 14-5, of which there are several, are evenly distributed on the stirring shaft 14-3 with rounded corners. The movable strips 14-5 are movably inserted into the strip-shaped grooves 17 opened on the inner wall of the rotating rod 14-1. Through the cooperation of the motor 13, the rotating rod 14-1 and the movable strips 14-5, the stirring shaft 14-3 can be rotated in the sand mixing chamber 10. While realizing the mixing of sand in the sand mixing chamber 10, the cooperation of the fixed cylinder 14-2 and the guide block 14-4 can also make the stirring shaft 14-3 move back and forth left and right during the rotation, thereby improving the mixing effect of sand in the sand mixing chamber 10.
[0041] When using this invention, unscrew the threaded cap 8 from the threaded feed port 7, then pour various types of sand into several sand storage chambers 6 through the threaded feed port 7, and then screw the threaded cap 8 back onto the threaded feed port 7 to seal the sand storage tank 2. When a certain type of sand is needed, pull the corresponding control block 12-4 forward to disengage the limiting block 12-6 from the limiting groove 15 and compress the spring 12-5. Then rotate the control block 12-4, which drives the control rod 12-2 to rotate via the polygonal plate 12-3. The control rod 12-2 drives the baffle plate 12-1 to tilt, allowing the sand in the storage chamber to fall into the mixing chamber 10 through the outlet 11.

After the required proportions of various sand materials in the sand mixing chamber 10 are reached, the control block 12-4 is rotated in the reverse direction to flip the baffle plate 12-1 to a horizontal state, closing the opening 11. The control block 12-4 is then released, and the spring 12-5 returns to its original position and extends, causing the control block 12-4 to move closer to the sand storage tank 2. The control block 12-4 drives the limiting block 12-6 to re-abut against the limiting groove 15, providing rotational limit for the control block 12-4. Then, the motor 13 can be started. The motor 13 drives the rotating rod 14-1 to rotate. The rotating rod 14-1 drives the stirring shaft 14-3 to rotate through the movable strip 14-5, so that the stirring shaft 14-3 stirs and mixes the various sand materials in the sand mixing chamber 10. During this process, the stirring shaft 14-3 will drive the guide block 14-4 to move back and forth in the reciprocating guide groove 16, so that the stirring shaft 14-3 can move back and forth left and right simultaneously while rotating, improving the mixing effect of the various sand materials in the sand mixing chamber 10.
[0042] Compared with the prior art, the beneficial effects of this utility model are:
[0043] By combining the vertical partition 5 and the horizontal partition 9, the interior of the sand storage tank 2 can be formed with multiple cavities to store different types of sand. With the cooperation of the sand control mechanism 12, the motor 13 and the sand mixing mechanism 14, different types of sand can be mixed according to the operation requirements, thereby achieving a more efficient surface treatment effect.
[0044] The connection between the threaded cover 8 and the gun body 1 can be achieved through the cooperation of the connecting belt 20 and the connecting ring 19, thus preventing the threaded cover 8 from falling off and being lost after being unscrewed from the threaded feed port 7.
[0045] The combination of observation window 21 and scale line 22 makes it easy for staff to understand the remaining amount of sand in sand storage chamber 6, thereby facilitating staff to judge the mixing ratio of each sand in sand mixing chamber 10.
[0046] The guide plate 18 can guide the sand in the sand storage cavity 6 to flow towards the opening 11, so as to prevent the sand from remaining in the sand storage cavity 6.
[0047] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
