Description

Technical Field

[0001] This invention belongs to the field of shot blasting machines, and specifically relates to an anti-clogging structure for shot blasting machines. Background Technology

[0002] Shot blasting machine is a casting equipment that uses high-speed shot to clean or strengthen the surface of castings. Shot blasting machine can simultaneously remove sand, core, and clean castings. In some regions, it is also colloquially called sandblasting machine or sandblasting machine. When using shot blasting machine, a corresponding feed pipe needs to be set up to continuously feed sand. However, because the shape of sand is irregular, the shot can easily get stuck inside the feed pipe due to mutual friction, which will affect the normal shot blasting operation.

[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this invention was created. It provides a shot blasting machine anti-clogging structure to solve the problem that existing shot blasting machines require the setting of corresponding feed pipes for continuous feeding of sand. However, due to the irregular shape of the sand, the shot is easily stuck inside the feed pipe due to mutual friction, which affects the normal shot blasting operation. Summary of the Invention

[0004] This invention proposes an anti-clogging structure for shot blasting machines, which solves the problem in existing technologies where a corresponding feed pipe is required for continuous feeding of sand. However, due to the irregular shape of the sand, the shot can easily get stuck inside the feed pipe due to mutual friction, thus affecting normal shot blasting operations.

[0009] In a preferred embodiment, a mounting plate is fixedly connected to the top surface of the connecting pipe. The main body of the mounting plate is circular, and the diameter of the mounting plate is larger than the diameter of the connecting pipe. The interior of the mounting plate has through holes arranged in a ring array. These through holes are connection holes, which are used to install fixing bolts. The mounting plate and the connection holes together form the hoisting structure for the device.

[0010] In a preferred embodiment, a telescopic tube is fixedly connected to the top surface of the guide plate. The main body of the telescopic tube is a telescopic structure, and the diameter of the telescopic tube is smaller than the diameter of the guide plate. A connecting plate is fixedly connected to the top surface of the telescopic tube.

[0027] like Figures 1-8As shown, an anti-clogging structure for a shot blasting machine includes: a housing 1, the main body of which is a hollow structure with a channel inside, the channel being narrower at the top and wider at the bottom for ejecting shot blasting material; a booster pump 101 fixedly connected to the left end face of the housing 1, the booster pump 101 being used for air extraction and ejection; an assembly pipe 102 fixedly connected to the top face of the booster pump 101, the main body of the assembly pipe 102 being a flexible structure, the assembly pipe 102 being connected to the air outlet of the booster pump 101 for air discharge; and a conduit 103 fixedly connected to the top face of the housing 1, the conduit 103 being a bidirectional through structure on both the top and bottom sides, the conduit 103 being through the top opening of the housing 1 for feeding material into the housing 1; and the top face of the conduit 103... A guide plate 104 is fixedly connected to the top. A guide rod 4 is fixedly connected to the bottom end face of the connecting plate 301. The main body of the guide rod 4 is a cylindrical structure. There are two guide rods 4, and the two guide rods 4 are fixedly connected to the bottom end face of the connecting plate 301 in a straight array. A base plate 401 is fixedly connected to the bottom end face of both guide rods 4. The main body of the base plate 401 is a circular structure.

[0028] The guide plate 104 has a circular structure, and its diameter is larger than that of the guide tube 103. The guide plate 104 has through holes, which are guide holes 105. There are two guide holes 105, arranged in a straight line on the left and right sides of the guide plate 104. The guide holes 105 and the guide plate 104 together form a guiding and conveying structure. A bracket 2 is fixedly connected to the rear end face of the housing 1. The bracket 2 is perpendicular to the rear end face of the housing 1. A motor 201 is installed at the bottom and is bolted to the position directly below the bracket 2. An output shaft is provided at the top of the motor 201, which is connected to a bearing seat in the bracket 2. A helical gear B208 is installed on the top output shaft of the motor 201. The helical gear B208 and the motor 201 together form a rotation drive structure. A rotating shaft 202 is installed inside the housing 1. There are two rotating shafts 202, and the two rotating shafts 202 are installed in a linear array inside the housing 1.

[0029] Among them, a helical gear A203 is coaxially mounted on the rear side of the left-side rotating shaft 202. The helical gear A203 is perpendicular to the helical gear B208 located at the top of the motor 201 and meshes with the helical gear B208 for transmission. Furthermore, a dial wheel 204 is fixedly connected to the outer side of both rotating shafts 202. The main body of the dial wheel 204 is circular, and the diameter of the dial wheel 204 is larger than the diameter of the rotating shaft 202. A dial plate 205 is fixedly connected in a ring array on the outer circumference of the dial wheel 204. The main body of the dial plate 205 is arc-shaped. Furthermore, the dial plate 205 and the dial wheel 204 together form a shot blasting structure. The front end of the rotating shaft 202 is fixedly connected to the guide plate 206. The main body of the guide plate 206 is a rectangular structure, and the top and bottom ends of the guide plate 206 are arc-shaped. A transmission gear 207 is also installed on the outer side of the two rotating shafts 202. The transmission gear 207 is located on the rear side of the guide plate 206, and the two transmission gears 207 mesh with each other. When one dial wheel 204 and the dial plate 205 are rotating, the other dial wheel 204 and the dial plate 205 are rotating synchronously.

[0030] The guide plate 104 has a telescopic tube 3 fixedly connected to its top surface. The telescopic tube 3 has a telescopic structure and its diameter is smaller than that of the guide plate 104. A connecting plate 301 is fixedly connected to the top surface of the telescopic tube 3. The connecting plate 301 has a circular structure and a connecting tube 302 is fixedly connected to its top surface. The connecting tube 302 has a hollow tubular structure and is fixedly connected to and communicates with the connecting plate 301. An mounting plate 303 is fixedly connected to the top surface of the connecting tube 302. The mounting plate 303 has a circular structure and its diameter is larger than that of the connecting tube 302. The mounting plate 303 has through holes arranged in a ring array inside. These through holes are connecting holes 304, which are used to install fixing bolts. The mounting plate 303 and the connecting holes 304 together form the hoisting structure for the device.

[0031] When in use, when the shot blasting machine needs to be connected, the mounting plate 303 fixedly connected to the top surface of the connecting pipe 302 can be connected to the main body of the material box used by the shot blasting machine. At the same time, the fixing bolt is passed through the connection hole 304 opened in the mounting plate 303 to realize the quick connection and limit operation of the current shot blasting machine body and the connecting pipe 302. After the connection is completed, the device can be powered on. When in use, the motor 201 installed at the bottom of the bracket 2 can be started to mesh with the helical gear B208 set on its top output shaft. The helical gear B208 meshes with the helical gear A203 set on the outside of the rotating shaft 202 to rotate the dial 204 set on the outside of the rotating shaft 202.

[0032] Furthermore, when a single dial wheel 204 rotates, the meshing transmission gear 207 installed on the outside of the rotating shaft 202 can drive another dial wheel 204 and the dial plate 205 to rotate, thus achieving rapid shot blasting. During shot blasting, the guide tube 103, telescopic tube 3, and connecting tube 302 installed on the top surface of the housing 1 can be used to quickly guide and transport the sand. The material entering the guide tube 103 and the dial wheel 204 and dial plate 205 installed on the outside of the rotating shaft 202 rotate at high speed to quickly eject the sand shot, thus achieving shot blasting. When in use, the booster pump 101 installed on the outside of the housing 1 can be started to supply air into the assembly tube 102 and then into the connecting tube 302 through the assembly tube 102, so that the sand shot entering the connecting tube 302 can be quickly pressurized and ejected, thereby achieving a more practical purpose.

[0033] Furthermore, when the guide plate 206 located at the front end of the rotating shaft 202 rotates, it can synchronously connect with the connecting rod 403 and the guide rod 404 fixedly connected to the bottom end face of the connecting plate 301. When the guide plate 206 contacts the guide rod 404 fixedly connected to the bottom end face of the connecting rod 403, the connecting plate 301 and the connecting pipe 302 fixedly connected to the top end face of the connecting plate 301 can move upward together, and stretch the telescopic pipe 3 located between the connecting plate 301 and the guide plate 104, so that the material in the telescopic pipe 3 can fall quickly. When the connecting plate 301 moves, the guide rod 4 located on the bottom end face of the connecting plate 301 can move along the guide hole 105 opened in the guide plate 104 to achieve fast and stable guidance.
