Description
Technical Field
[0001] This utility model relates to the field of building decoration construction technology, and in particular to a sandblasting device for building decoration construction. Background Technology
[0002] In the process of building materials decoration and renovation, sandblasting is a common surface treatment and preparation process. By sandblasting the wall surface, dirt, paint, rust, old coatings and other unclean substances can be effectively cleaned to ensure that new coatings or other building materials can be firmly adhered to the surface.
[0003] In existing equipment, people often use the nozzle of a handheld sandblasting device to sandblast and clean the surface of materials, thereby ensuring the cleanliness of the surface.
[0004] However, in actual use, cleaning the surface of building materials by hand often cannot guarantee that the sandblasting range can fully cover all corners of the wall. It often requires the construction worker to constantly swing their arm to adjust the sandblasting position, making the whole process quite laborious. At the same time, during the sandblasting process, the sandblasting material may come into contact with moisture in the air during storage or transportation, resulting in a certain amount of small solid lumps. This makes it difficult for the sandblasting pump to spray them out fully. In view of this, we propose a sandblasting device for building decoration and renovation construction. Utility Model Content
[0005] The main objective of this invention is to provide a sandblasting device for building decoration and renovation, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model proposes a sandblasting device for building decoration and renovation construction, comprising a vehicle body, a storage box fixedly connected to the upper surface of the vehicle body, a mounting frame fixedly connected to the upper surface of the vehicle body, and a reciprocating sandblasting device provided at the upper end of the mounting frame. A stirring device is provided inside the storage box.
[0007] The reciprocating sandblasting device includes a feed pipe, the lower end of which is rotatably connected to a connecting block. A contact block is fixedly connected to the outer arc surface of the connecting block.
[0008] The device has a nozzle, a limit block is fixedly connected to the upper surface of the connecting block, and a stop bar is fixedly connected to the lower surface of the mounting bracket.
[0009] Preferably, the stirring device includes a motor, a rotating shaft is fixedly connected to the output shaft of the motor, a sliding rod is fixedly connected to the outer surface of the rotating shaft, a metal strip is attached to the outer surface of the sliding rod, a sieve plate is slidably connected to the outer surface of the sliding rod, and an arc-shaped rod is fixedly connected to the inner surface of the storage box.
[0010] Preferably, a caster wheel is fixedly connected to the lower surface of the vehicle body, a handle is fixedly connected to the upper surface of the vehicle body, and a through groove is provided at the upper end of the mounting bracket.
[0011] Preferably, the upper end of the storage box is fitted with a cover, the outer surface of the storage box is fixedly connected to a sandblasting pump, the upper end of the feed pipe is connected to the sandblasting pump through a hose, and the lower end of the outer arc surface of the feed pipe is provided with a rectangular protrusion.
[0012] Preferably, the upper surface of the connecting block has a through hole, the upper surface of the connecting block has a cylindrical groove, the interior of the connecting block is hollow, and the nozzle is generally inclined.
[0013] Preferably, there are two sets of limiting blocks and two sets of stop bars, and the two sets of stop bars are symmetrically distributed with the center line of the mounting frame as the axis of symmetry.
[0014] Preferably, the lower end of the motor is fixedly connected to the cover plate of the storage box, the outer surface of the rotating shaft is rotatably connected to the cover plate of the storage box, and a rectangular groove is formed on the inner surface of the sliding rod.
[0015] Preferably, the end of the arc-shaped rod away from the storage box is set as a hemispherical shape, a set of sliding rods is provided at both the upper and lower ends of the sieve plate, and the metal strip is set as an arc shape.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] (1) When the sandblasting device for building materials decoration is in use, the sandblasting pump on the outer surface of the storage tank can continuously spray the material inside the storage tank outward. At the same time, due to the reaction force of the sprayed material, the connecting block and the feed pipe will be driven to slide in one direction on the inner surface of the mounting frame. When the connecting block moves to the end of the groove inside the mounting frame, the contact block will contact the stop bar and be pushed by the stop bar to rotate. At this time, the sandblasting angle of the nozzle will also be driven to change, so that the reaction force can be
[0018] The connecting block and the feed pipe move in the opposite direction, so that the device can perform reciprocating sandblasting on a designated area without manual intervention, and the sandblasting process is relatively uniform.
[0019] (2) When using the sandblasting device for building materials decoration, the material to be sandblasted needs to be placed inside the storage box. At this time, the cover can be closed and the motor can be started. During the operation of the motor, the rotating shaft and the sliding rod on it will rotate continuously. During the rotation of the sliding rod, the screen plate will be continuously driven to rotate and contact the arc rod inside the storage box. Therefore, the screen plate will be continuously pushed towards the rotating shaft. At the same time, when the screen plate moves away from the arc rod, the metal strip will push the screen plate outward due to its own elasticity. This allows the screen plate to continuously vibrate and beat the material inside the storage box, and the clumps of impurities inside can be broken into smaller sand particles, thereby improving the sandblasting efficiency.

[0032] Please refer to Figures 1-5. This utility model provides a technical solution: a sandblasting device for building decoration and renovation construction, including a vehicle body 4, a storage box 1 fixedly connected to the upper surface of the vehicle body 4, a mounting frame 5 fixedly connected to the upper surface of the vehicle body 4, and a reciprocating sandblasting device 2 provided at the upper end of the mounting frame 5. A stirring device 3 is provided inside the storage box 1;
[0033] The reciprocating sandblasting device 2 includes a feed pipe 201, a connecting block 202 rotatably connected to the lower end of the feed pipe 201, a contact block 203 fixedly connected to the outer arc surface of the connecting block 202, a nozzle 206 fixedly connected to the outer arc surface of the connecting block 202, a limit block 205 fixedly connected to the upper surface of the connecting block 202, and a stop bar 204 fixedly connected to the lower surface of the mounting bracket 5.
[0034] Specifically, casters are fixedly connected to the lower surface of the vehicle body 4, thus enabling this device to...
[0035] Pushed to any sandblasting position, a handle is fixedly connected to the upper surface of the vehicle body 4. A through-slot is opened at the upper end of the mounting bracket 5, allowing the feed pipe 201 to slide within the slot. A cover is snapped onto the upper end of the storage tank 1. A sandblasting pump is fixedly connected to the outer surface of the storage tank 1. This sandblasting pump is a conventional sandblasting device, capable of blasting out the material inside the storage tank 1; its principle will not be elaborated upon. The upper end of the feed pipe 201 is connected to the sandblasting pump via a hose, allowing the sandblasting pump to continuously deliver material into the feed pipe 201. A rectangular protrusion is provided at the lower end of the outer arc surface of the feed pipe 201. This rectangular protrusion can rotate within the limitation range of the two side limit blocks 205, ensuring that the reaction force of the nozzle 206 can continuously push the connecting block 202 and the feed pipe 201 to move. The connecting block 202... The upper surface of the connecting block 202 has a through hole, allowing it to connect with the feed pipe 201. The upper surface of the connecting block 202 has a cylindrical groove, which can accommodate the protrusion on the outer surface of the feed pipe 201 and the change in relative angle between it and the protrusion. The interior of the connecting block 202 is hollow. The nozzle 206 is set in an inclined shape. There are two sets of limiting blocks 205 and two sets of stop bars 204. The two sets of stop bars 204 are symmetrically distributed about the center line of the mounting frame 5. Therefore, when the contact block 203 moves to both ends of the mounting frame 5, it can be pushed by one set of stop bars 204 and drive the connecting block 202 to rotate.
[0036] In this embodiment of the present invention, the stirring device 3 includes a motor 301, a rotating shaft 302 is fixedly connected to the output shaft of the motor 301, a sliding rod 305 is fixedly connected to the outer surface of the rotating shaft 302, a metal strip 306 is attached to the outer surface of the sliding rod 305, a sieve plate 304 is slidably connected to the outer surface of the sliding rod 305, and an arc-shaped rod 303 is fixedly connected to the inner surface of the storage box 1.
[0037] Specifically, the lower end of the motor 301 is fixedly connected to the cover plate of the storage box 1, the outer surface of the rotating shaft 302 is rotatably connected to the cover plate of the storage box 1, and the inner surface of the slide rod 305 is provided with a rectangular groove, so that the screen plate 304 can only move in its internal groove. The end of the arc-shaped rod 303 away from the storage box 1 is set as a hemispherical shape, so that it can continuously push the screen plate 304 to move inside the slide rod 305 when it contacts the screen plate 304. A set of slide rods 305 is provided at both the upper and lower ends of the screen plate 304. The metal strip 306 is set as an arc shape. The metal strip 306 itself is relatively thin, so that it can be squeezed into an arc shape by the slide rods 305 on both sides.
[0038] When in a certain state, it generates a certain degree of elasticity and can continuously push the sieve plate 304 to vibrate.
[0039] During operation (or use), the material to be sandblasted needs to be placed inside the storage bin 1. At this time, the cover can be closed and the motor 301 can be started. During the operation of the motor 301, the rotating shaft 302 and the sliding rod 305 on it will rotate continuously. During the rotation of the sliding rod 305, the screen plate 304 will be continuously driven to rotate and contact the arc-shaped rod 303 inside the storage bin 1. Therefore, the screen plate 304 will be continuously pushed towards the rotating shaft 302. At the same time, when the screen plate 304 moves away from the arc-shaped rod 303, the metal strip 306 will push the screen plate 304 outward due to its own elasticity. This allows the screen plate 304 to continuously vibrate and beat the material inside the storage bin 1, and break the clumps of impurities inside into smaller sand particles, thereby improving the sandblasting efficiency.
[0040] Simultaneously, during the use of this device, the sandblasting pump on the outer surface of the storage tank 1 continuously sprays the material inside the storage tank 1 outward. Due to the reaction force of the sprayed material, the connecting block 202 and the feed pipe 201 will be driven to slide unidirectionally on the inner surface of the mounting frame 5. When the connecting block 202 moves to the end of the groove inside the mounting frame 5, the contact block 203 will contact the stop bar 204 and be pushed by the stop bar 204 to rotate. At this time, the sandblasting angle of the nozzle 206 will also be driven to change, so that the reaction force can drive the connecting block 202 and the feed pipe 201 to move in the opposite direction. Thus, this device can achieve reciprocating sandblasting of a designated area without manual intervention, and the sandblasting process is relatively uniform.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
