Description
Technical Field
[0001] This utility model relates to the field of mechanical workpiece processing technology, and in particular to a spraying device for engineering machinery. Background Technology
[0002] During the manufacturing process of construction machinery and equipment, spraying equipment is required to coat the components of the equipment. The coating applied by the spraying equipment isolates the equipment from external corrosive substances, protects the equipment from external corrosive substances, and extends the service life of the equipment.
[0003] While existing spraying equipment can spray coating components of construction machinery, some paint often remains in the spraying components after spraying. After prolonged spraying, the paint residue not only reduces spraying efficiency but may also clog the components, preventing the spraying equipment from performing normal spraying and resulting in poor performance. To address this, we propose a spraying device for construction machinery. Utility Model Content
[0004] To address the technical problem of poor performance of existing spraying devices, this utility model provides a spraying device for engineering machinery.
[0005] This utility model is achieved using the following technical solution: an engineering machinery spraying device, comprising a housing and a paint chamber and a water storage chamber formed within the housing. A connecting plate is provided on one side of the housing, and a bearing plate fixed to the outside of the housing is fixed to the side of the connecting plate near the housing. Mounting plates fixed to the outside of the housing are fixed to both sides of the bearing plate. A loading plate is provided above the bearing plate, located between the two mounting plates. A fixing block fixed to the outside of the housing is hinged to the outer side of the loading plate near one end of the housing. A delivery pump is fixed to the inner wall of the top of the water storage chamber. The input end of the delivery pump is connected to an input pipe extending into the paint chamber. A cleaning component is provided inside the housing. The output end of the delivery pump is connected to an output pipe extending into the outside of the housing. Multiple nozzles fixed to the bottom side of the loading plate are installed on the output pipe. When the components of the engineering machinery are placed on the bearing plate, the operation of the delivery pump drives the input pipe to draw paint from the paint chamber and deliver it to the inside of the output pipe. The paint entering the output pipe will then be sprayed out through the nozzles, and the paint sprayed out through the nozzles will spray the components on the bearing plate.
[0006] As a further improvement to the above solution, the cleaning component includes an installation hole formed in the inner wall between the paint chamber and the water storage chamber. An installation block fixed to the inner wall of the paint chamber is inserted into the installation hole. The installation block has a conveying chamber. One end of an input pipe located inside the paint chamber extends into the conveying chamber. The installation block inside the paint chamber is connected to an input pipe two communicating with the conveying chamber.

A transmission belt is provided on the outside of the transmission wheel to drive the transmission wheel. Multiple stirring rods rotating inside the paint chamber are fixed on the outer wall of the connecting shaft inside the paint chamber. Through the operation of the cleaning component, residual paint in the input pipe, output pipe and nozzle can be cleaned, and the paint inside the paint chamber can be stirred to prevent the paint inside the paint chamber from settling after a long period of time, thereby effectively improving the quality of the paint.
[0007] As a further improvement to the above solution, the outer side of the box is hinged with a first movable door and a second movable door. The first movable door is connected to the paint chamber, and the second movable door is connected to the water storage chamber. The outer sides of the first movable door and the second movable door are provided with sealing rings. By opening the first movable door and the second movable door, users can easily inspect and maintain the components inside the box.
[0008] As a further improvement to the above solution, the loading plate has a threaded hole one at the end away from the box body, and the box body has a threaded hole two at the side near the connecting plate. A positioning plate is fixed to the top of the connecting plate near the box body. Bolts that are threaded to the positioning plate and threaded to the threaded holes one and two are threadedly connected. A drive sleeve is embedded at the end of the bearing plate near the connecting plate. A threaded post passes through the internal thread of the drive sleeve. One end of the threaded post is rotatably connected to the positioning plate, and the other end of the threaded post is fixed with a handle. Through the operation of the above components, the loading plate and the nozzles on the loading plate can be stored and protected, and the corresponding position of the bearing plate can be adjusted.
[0009] As a further improvement to the above solution, a guide hole is provided at the end of the bearing plate away from the connecting plate, and a guide rod slides through the guide hole. A fixing plate is fixed to the top of the guide rod and fixed to the box body. Through the cooperation of the guide hole and the guide rod, the displacement of the bearing plate can be limited, thereby improving the stability of the bearing plate.
[0010] As a further improvement to the above solution, the bearing plate is provided with a connecting groove, and the loading plate slides in conjunction with the connecting groove. Through the connecting groove, the bearing plate can be prevented from interfering with the rotation of the loading plate.
[0011] As a further improvement to the above solution, butterfly valve one and butterfly valve two are installed on the outside of the box. Butterfly valve one is connected to the paint chamber, and butterfly valve two is connected to the water storage chamber. Through butterfly valve one, the user can conveniently inject paint into the paint chamber, and through butterfly valve two, the user can conveniently inject water into the water storage chamber.
[0012] As a further improvement to the above solution, the loading plate and the guide rod are offset, and the output pipe is a soft water pipe. By using a loading plate that is offset from the guide rod, the guide rod can be prevented from interfering with the rotation of the loading plate.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0023] Combination Figure 1 and Figure 2 This embodiment of an engineering machinery spraying device includes a housing 1 and a paint chamber 2 and a water storage chamber 3 opened inside the housing 1. A connecting plate 4 is provided on one side of the housing 1. A bearing plate 5 fixed to the outside of the housing 1 is fixed to the side of the connecting plate 4 near the housing 1. Mounting plates fixed to the outside of the housing 1 are fixed to both sides of the bearing plate 5. A loading plate 6 is provided above the bearing plate 5, located between the two mounting plates. A fixing block fixed to the outside of the housing 1 is hinged to the outside of the loading plate 6 near one end of the housing 1. A delivery pump is fixed to the inner wall of the top of the water storage chamber 3. The input end of the delivery pump is connected to an input pipe extending into the paint chamber 2. A cleaning assembly is provided inside the housing 1. The output end of the delivery pump is connected to an output pipe 7 extending into the outside of the housing 1. Multiple nozzles 8 fixed to the bottom side of the loading plate 6 are installed on the output pipe 7.
[0024] The implementation principle of the engineering machinery spraying device in this application embodiment is as follows: When it is necessary to spray the components of the engineering machinery equipment, the components of the engineering machinery equipment can be placed on the support plate 5. Then, by running the delivery pump, the input pipe 1 draws the paint from the paint chamber 2 and delivers it to the output pipe 7. At this time, the paint entering the output pipe 7 will be sprayed out through the nozzle 8. The components on the support plate 5 can be sprayed with the paint sprayed out by the nozzle 8. By running the cleaning component, the residual paint in the output pipe 7 and the nozzle 8 can be cleaned.
[0025] Combination Figure 4This embodiment, based on Embodiment 1, further improves upon the following: the cleaning component includes an installation hole formed in the inner wall between the paint chamber 2 and the water storage chamber 3. An installation block 9, fixed to the inner wall of the paint chamber 2, is inserted into the installation hole. The installation block 9 has a conveying chamber 10. One end of an input pipe located inside the paint chamber 2 extends into the conveying chamber 10. The installation block 9 inside the paint chamber 2 is connected to an input pipe 11 communicating with the conveying chamber 10. The installation block 9 inside the water storage chamber 3 is connected to an input pipe 12 communicating with the conveying chamber 10. A piston 13, sliding within the conveying chamber 10, is provided between the input pipe 11 and the input pipe 12. The end of an output pipe 7 located inside the paint chamber 2 is located between the input pipe 11 and the input pipe 12. A transmission rod 15 is slidably inserted through the middle of block 9. The outer wall of the transmission rod 15, located inside the conveying chamber 10, is threaded. A threaded sleeve 14, fitted onto the piston 13, is threaded onto the outer wall of the transmission rod 15. One end of the transmission rod 15 is rotatably connected to the inner wall of the water storage chamber 3, and the other end extends to the outside of the housing 1, where it is connected to a motor fixed to the outside of the housing 1. The motor is a forward and reverse stepper motor. A connecting hole is provided in the inner wall between the paint chamber 2 and the water storage chamber 3. A connecting shaft 16 is slidably inserted through the connecting hole. One end of the connecting shaft 16 is rotatably connected to the inner wall of the paint chamber 2, and the other end is rotatably connected to the inner wall of the water storage chamber 3. The outer wall of the connecting shaft 16 inside the water storage chamber 3 and the transmission rod 14 inside the water storage chamber 3 are connected. Each rod 15 has a transmission wheel fixedly sleeved on its outer wall. A transmission belt, engaging with the transmission wheel, is located outside the transmission wheel. Multiple stirring rods 17, rotating within the paint chamber 2, are fixed to the outer wall of the connecting shaft 16 inside the paint chamber 2. When paint needs to be extracted from the paint chamber 2, the motor drives the transmission rod 15 to rotate. The rotating transmission rod 15, through its threaded engagement with the screw sleeve 14, causes the screw sleeve 14 and piston 13 to move. When the piston 13 moves between the output pipe 7 and the input pipe 12, the input pipe 11 extracts the paint from the paint chamber 2 and transfers it into the conveying chamber 10. The paint in the conveying chamber 10 is then transported to the input pipe 1 and then to the output pipe 7. Paint entering the output pipe 7 will be sprayed out through the nozzle 8. When it is necessary to clean the residual paint inside the input pipe 1, output pipe 7, and nozzle 8, the motor can drive the transmission rod 15 to rotate. Through the threaded engagement of the rotating transmission rod 15 and the screw sleeve 14, the screw sleeve 14 and piston 13 are moved. When the piston 13 moves between the output pipe 7 and the input pipe 2 11, the input pipe 3 12 will draw clean water from the water storage chamber 3 and transport it to the delivery chamber 10. The clean water entering the delivery chamber 10 will then be transported to the input pipe 1 and then to the output pipe 7. The water entering the output pipe 7 will then be sprayed out through the nozzle 8.At this time, the water flowing through the input pipe 1, output pipe 7, and nozzle 8 will clean the residual paint inside these pipes, preventing them from clogging and hindering the spraying device's normal operation. When the transmission rod 15 rotates, the transmission wheel and belt will drive the connecting shaft 16 to rotate. This rotating shaft 16 will then drive the stirring rod 17 to stir the paint inside the paint chamber 2, preventing sedimentation after prolonged storage and effectively improving paint quality.
[0026] The outer side of the housing 1 is hinged with movable door 1 and movable door 2. Movable door 1 is connected to paint chamber 2 and movable door 2 is connected to water storage chamber 3. Movable door 1 and movable door 2 are provided with sealing rings on their outer sides. By opening movable door 1 and movable door 2, users can easily inspect and maintain the components inside the housing 1.
[0027] Combination Figure 3 This embodiment, based on embodiment 1, further improves upon the following: A threaded hole 1 is provided at the end of the loading plate 6 away from the housing 1; a threaded hole 2 is provided on the side of the housing 1 near the connecting plate 4; a positioning plate 20 is fixed to the top of the connecting plate 4 near the housing 1; a bolt 21 threadedly connected to the positioning plate 20, engaging with the threads of threaded holes 1 and 2; a drive sleeve 18 is embedded at the end of the bearing plate 5 near the connecting plate 4; a threaded post 19 is threaded through the internal threads of the drive sleeve 18; one end of the threaded post 19 is rotatably connected to the positioning plate 20; and a handle is fixed to the other end of the threaded post 19. Through the engagement of the bolt 21 and the threaded hole 1, the loading plate 6 can be fixed to the positioning plate 20. When the spraying device is not needed, the bolt 21 can be rotated to move the bolt 21 away from the positioning plate 20. Then the loading plate 6 can be pushed to deflect it. When the deflected loading plate 6 is at the same level as the box 1, the bolt 21 can be loaded onto the loading plate 6. Then the bolt 21 can be rotated to fix the bolt inside the threaded hole 2. At this time, the loading plate 6 and the spray head on the loading plate 6 are housed and protected between the two mounting plates. By turning the handle, the threaded post 19 can be rotated. Through the threaded engagement between the threaded post 19 and the drive sleeve 18, the drive sleeve 18 and the bearing plate 5 can be vertically displaced. At this time, the corresponding position of the bearing plate 5 can be adjusted.
[0028] A guide hole is provided at the end of the bearing plate 5 away from the connecting plate 4. A guide rod 22 slides through the guide hole. A fixing plate is fixed to the top of the guide rod 22 and fixed to the box body 1. Through the cooperation of the guide hole and the guide rod 22, the displacement of the bearing plate 5 can be limited, thereby improving the stability of the bearing plate 5.
[0029] The support plate 5 has a connecting groove, and the loading plate 6 slides in the connecting groove. The connecting groove can prevent the support plate 5 from interfering with the rotation of the loading plate 6.
[0030] Butterfly valve 1 and butterfly valve 2 are installed on the outside of the housing 1. Butterfly valve 1 is connected to the paint chamber 2, and butterfly valve 2 is connected to the water storage chamber 3. Through butterfly valve 1, the user can conveniently inject paint into the paint chamber 2, and through butterfly valve 2, the user can conveniently inject water into the water storage chamber 3.
[0031] The loading plate 6 is offset from the guide rod 22, and the output pipe 7 is a soft water pipe. By offsetting the loading plate 6 from the guide rod 22, the guide rod 22 can be prevented from interfering with the rotation of the loading plate 6.
[0032] Working Principle: When spray painting is required on components of engineering machinery, the position of the bearing plate 5 can be adjusted according to the usage requirements. Turning the handle rotates the threaded column 19, causing it to rotate. Through the threaded engagement between the threaded column 19 and the drive sleeve 18, the drive sleeve 18 and the bearing plate 5 are vertically displaced. The position of the bearing plate 5 can then be adjusted. After adjusting the position of the bearing plate 5, the components of the engineering machinery are placed on the bearing plate 5. Then, the motor drives the transmission rod 15 to rotate. Through the threaded engagement between the rotating transmission rod 15 and the screw sleeve 14, the screw sleeve 14 and the piston 13 are displaced. When the piston 13 is displaced between the output pipe 7 and the input pipe 12, the components are transported by the delivery pump... The system drives the input pipe 11 to draw paint from the paint chamber 2 and into the conveying chamber 10. The paint in the conveying chamber 10 is then conveyed to the input pipe 1, and then to the output pipe 7. The paint in the output pipe 7 is then sprayed out through the nozzle 8, which coats the components on the support plate 5. When the transmission rod 15 rotates, the transmission wheel and belt work together to drive the connecting shaft 16 to rotate. This rotating connecting shaft 16 drives the stirring rod 17 to stir the paint in the paint chamber 2, preventing sedimentation after prolonged storage and effectively improving the paint's viscosity. Regarding quality control, when it is necessary to clean residual paint inside the input pipe 1, output pipe 7, and nozzle 8, the motor drives the transmission rod 15 to rotate. Through the threaded engagement of the rotating transmission rod 15 and the screw sleeve 14, the screw sleeve 14 and piston 13 are displaced. When piston 13 moves between output pipe 7 and input pipe 2 11, the input pipe 3 12, along with the operation of the delivery pump, will draw clean water from the water storage chamber 3 and deliver it to the delivery chamber 10. The clean water entering the delivery chamber 10 will then be delivered to the input pipe 1, and then to the output pipe 7. The water entering the output pipe 7 will then be sprayed out through nozzle 8. At this point, the operation of the input pipe 1, output pipe 7, and nozzle 8... The internal water will clean the residual paint inside the input pipe 1, output pipe 7 and nozzle 8, preventing the paint residue in the input pipe 1, output pipe 7 and nozzle 8 from clogging the input pipe 1, output pipe 7 and nozzle 8, thus preventing the spraying device from performing normal spraying work. When the user does not need to use the spraying device, the bolt 21 can be rotated to move the bolt 21 away from the positioning plate 20. Then the loading plate 6 can be pushed to deflect the loading plate 6. When the deflected loading plate 6 is at the same level as the box 1, the bolt 21 can be loaded onto the loading plate 6. Then the bolt 21 can be rotated to fix the bolt inside the threaded hole 2. At this time, the loading plate 6 and the nozzle on the loading plate 6 are stored and protected between the two mounting plates.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
