Description

Technical Field

[0001] This invention belongs to the technical field of grinding machines, and in particular relates to a rust removal and grinding machine for construction sites. Background Technology

[0002] Rust removal and grinding machines for construction sites play a vital role in the construction industry and are indispensable pieces of specialized equipment. These machines, with their powerful functions, can quickly remove rust and dirt from the surfaces of building materials, thereby significantly improving construction efficiency and ensuring project progress and quality.

[0003] In actual construction, especially when welding is required at the ends of materials, such as for door, window, or railing supports, the use of rust removal and grinding machines is crucial. Since rust can severely affect welding quality and potentially shorten the subsequent service life, the ends of the materials must be finely ground before welding. This process not only requires removing rust but also ensuring a smooth end surface, laying the foundation for high-quality welding.

[0004] Currently, grinding of material end faces is mostly done using benchtop grinding machines. However, in actual operation, the sparks and metal fragments generated during grinding pose significant safety hazards. These sparks not only rapidly deteriorate the working environment and increase the risk of operators inhaling fly ash, thus causing injury, but also, because operators need to closely monitor the grinding area, the flying fragments can easily enter the eyes or other sensitive areas, causing serious injury. Summary of the Invention

[0005] This invention proposes a rust removal and grinding machine for construction sites, which has the advantages of enclosed protection and air purification, in order to solve the problem mentioned in the background art that the sparks and fragments generated during the grinding process can easily cause injury to the operator.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rust removal and grinding machine for construction sites, comprising: a support base with an outer shell sleeve installed on its surface, and an observation tube movably installed at the end of the outer shell sleeve; a drive motor installed at the end of the outer shell sleeve, and the output shaft of the drive motor being able to drive the grinding head and fan blade located inside the outer shell sleeve to rotate; and a feeding pipe fixed at the end of the outer shell sleeve.

[0007] Furthermore, a water storage cavity is provided on the inner side of the support base, and an exhaust pipe is tightly fitted on the outer side of the outer shell.

[0008] Furthermore, a support roller for clamping the observation cylinder is movably installed inside the outer casing. The grinding head and the drive motor rotate synchronously through a transmission gear set movably installed inside the outer casing. A drive pressure sleeve is fixed on the grinding head, and a cleaning rod is fixedly installed on the surface of the drive pressure sleeve.

[0009] Furthermore, the support rollers are provided in three sets, and the three sets of support rollers are arranged at equal angles, with each set containing two support rollers.

[0010] Furthermore, a pressure-boosting protrusion is provided on the outer side of the drive sleeve.

[0011] Furthermore, a connecting groove is provided at the bottom of the outer casing for communication between the inner cavity of the outer casing and the water storage cavity.

[0012] Furthermore, the two support rollers in the set are driven by the meshing of the adjustable gear set, and an adjusting piston is movably installed on the outside of the outer casing, and a reset push spring is connected between the adjusting piston and the outer casing; a limited moving gear row is fixed at one end of the adjusting piston, and an adjusting arm is fixed at the other end.

[0013] Furthermore, an alarm bell is fixed on the support base, and a liquid measuring baffle is securely connected to the bottom of the adjusting piston. Beneficial effects

[0014] This invention provides a material rust removal and grinding machine specifically designed for construction sites. Its unique design features a robust outer shell and a transparent observation tube that completely and safely enclose the grinding head. This design not only ensures safety during operation but also significantly improves the efficiency and quality of grinding work. When fine grinding of the ends of building materials is required, such as for the pretreatment of door and window frames or railing supports, the grinding head rotates efficiently under driving force, quickly removing rust and polishing the material surface.

[0015] In this process, the transparent observation tube plays a crucial role. It not only allows operators to clearly observe the real-time status of the grinding area, ensuring the accuracy and uniformity of grinding, but its robust structure also effectively prevents metal fragments and fly ash generated during grinding from splashing outwards, thereby greatly reducing the potential threat to operators and the surrounding environment.

[0016] Furthermore, this rust removal and grinding machine is equipped with high-speed rotating fan blades. While the grinding head is performing grinding operations, the fan blades operate, powerfully drawing external airflow into the inner cavity of the outer casing. Ultimately, the airflow carrying fly ash is guided into the built-in water storage chamber. As a crucial element in air purification, the water storage chamber is filled with an appropriate amount of water or other suitable media. When the fly ash airflow enters the water storage chamber, the fly ash particles are effectively adsorbed and settled by the media, thus achieving efficient fly ash treatment. This process not only prevents dust from flying everywhere on the construction site but also significantly improves the operating environment and protects the respiratory health of operators.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figure 1 As can be seen, the support base 1 can be installed in the required position using the positioning holes at its four corners. The outer casing 2 is fastened to the top of the support base 1 with bolts, combined with... Figure 2 As can be seen, an observation cylinder 3 is movably installed at the end of the outer casing 2. The observation cylinder 3 is transparent, so that the operator can use the observation cylinder 3 to observe the grinding state of the material inside the outer casing 2 in real time.

[0021] The drive motor 5 is securely connected to the end of the outer casing 2. The output shaft of the drive motor 5 drives the grinding head 13 located inside the observation cylinder 3 to rotate. The rotating grinding head 13 grinds the material, thereby removing burrs and rust from the material ends. Furthermore, to prevent grinding debris from flying outwards, the end of the outer casing 2 has a feed pipe 4 secured with bolts. The feed pipe 4 not only determines the material feeding position but also further prevents grinding debris from flying outwards by blocking it.

[0022] Combination Figure 2It is evident that a fan blade 11 is securely connected to the output shaft of the drive motor 5. When the drive motor 5 rotates the grinding head 13, the fan blade 11 rotates synchronously, drawing external airflow through the feed pipe 4 into the inner cavity of the outer casing 2. This prevents the fly ash generated during grinding from scattering outwards. Furthermore, the airflow inside the feed pipe 4 always tends to flow into the inner cavity of the outer casing 2, further reducing the kinetic energy of debris splashing from the inside of the feed pipe 4 and decreasing the likelihood of debris flying out of the feed pipe 4. Regarding the handling of fly ash and debris, combined with... Figure 2 It is known that a water storage cavity 100 for storing liquid medium is provided on the inner side of the support base 1. The liquid medium is preferably water. When the fan blade 11 draws the external airflow into the inner cavity of the outer casing 2, the airflow can be introduced into the liquid medium in the water storage cavity 100 by using the exhaust pipe 15 fastened on the outside of the outer casing 2, thereby realizing the absorption and sedimentation of fly ash.

[0023] In practical applications, by connecting the drive motor 5 to the power supply, the drive motor 5 is forced to drive the fan blade 11 and the grinding head 13 to rotate synchronously. The operator inserts the end of the material to be ground through the feed pipe 4, thereby using the rotating grinding head 13 to grind the end of the material.

[0024] During the grinding process, the observation tube 3 allows for real-time monitoring of the material's grinding status. Simultaneously, the fan blade 11 rotates, causing external airflow to flow into the inner cavity of the outer casing 2 through the feed pipe 4. This blows the fly ash and debris generated during grinding into the exhaust pipe 15, which then blows the airflow containing fly ash into the water storage chamber 100 filled with liquid medium, thus cleaning up the fly ash. This method not only prevents fly ash and debris from harming operators but also autonomously purifies the air and collects impurities during the grinding process, significantly increasing environmental cleanliness.

[0025] Example 2 is a further improvement on Example 1. Since the observation tube 3 is made of transparent material, after prolonged use, fly ash and other impurities will adhere to the inside of the observation tube 3. This will cause the observation tube 3 to be obstructed by these impurities, making it impossible to clearly see the grinding state of the material inside the outer casing 2. To solve this problem, please refer to... Figures 2-4 It can be clearly seen that a support roller 6 for clamping the observation cylinder 3 is movably installed on the inner side of the outer casing 2. There are three sets of support rollers 6, which are arranged at equal angles to each other, thereby achieving stable clamping of the observation cylinder 3. Each set of support rollers 6 consists of two rollers, which are located on the inner and outer sides of the observation cylinder 3, respectively, to ensure that the support rollers 6 firmly clamp the observation cylinder 3.

[0026] from Figure 4It can be seen that a transmission gear set 12 is movably installed inside the outer casing 2, and the transmission gear set 12 consists of two transmission gears. One transmission gear is coaxially fixed to the output shaft of the drive motor 5, and the other transmission gear is coaxially fastened to the grinding head 13. The grinding head 13 can rotate by the meshing of the two transmission gears. Figure 3 It is evident that the intervention of the transmission gear set 12 forces the grinding head 13 and the observation cylinder 3 to be non-coaxial. Based on this, the drive sleeve 14 is coaxially and securely fastened to the grinding head 13, and a cleaning rod 141 is fixedly mounted on the surface of the drive sleeve 14. While the drive sleeve 14 rotates with the grinding head 13, the cleaning rod 141 can wipe and clean the inside of the observation cylinder 3, thereby ensuring the transparency of the observation cylinder 3.

[0027] In practical applications, the drive motor 5 drives the fan blade 11 and the grinding head 13 to rotate synchronously, thereby achieving the grinding work described in Embodiment 1. Furthermore, as the grinding head 13 drives the drive sleeve 14 to rotate synchronously, the observation cylinder 3 experiences increased rotational resistance due to being clamped by the support roller 6. When the drive sleeve 14 drives the cleaning rod 141 to move inside the observation cylinder 3, the cleaning rod 141 wipes the inside of the observation cylinder 3, ensuring greater transparency and preventing operator interference.

[0028] Based on this, combined Figure 3 As can be seen, a pressure-boosting protrusion 140 is provided on the outer side of the drive sleeve 14. When the drive sleeve 14 rotates to contact the inner side of the observation cylinder 3, it increases the contact strength between the observation cylinder 3 and the drive sleeve 14, forcing the observation cylinder 3 to rotate synchronously with the drive sleeve 14, thereby rotating the cleaned observation cylinder 3 upwards for easy observation by the operator. Through the intermittent rotation of the observation cylinder 3, the cleaning rod 141 is forced to thoroughly clean the inner side of the observation cylinder 3, ensuring that the operator can observe the degree of grinding of the material using the observation cylinder 3.

[0029] As a supplement to Example 2, in order to further achieve cleaning of the observation tube 3, combined with Figure 2 and Figure 5 It can be clearly seen that the bottom of the outer casing 2 is provided with a connecting groove 200 for the inner cavity of the outer casing 2 and the water storage cavity 100 to communicate. The connecting groove 200 allows the medium in the water storage cavity 100 to enter the inner bottom of the observation tube 3. When the cleaning rod 141 wipes the inner bottom of the observation tube 3, the medium between the two further ensures the cleanliness of the cleaning rod 141 and ensures that the observation tube 3 can always be in a relatively transparent state.

[0030] Example 3 is a further improvement on Example 2. In practical application, even when the grinding head 13 is not grinding, the cleaning rod 141 will still wipe the observation cylinder 3. Since cleaning is done through friction, prolonged friction will cause wear and tear on the cleaning rod 141. To reduce the unnecessary wear and tear on the cleaning rod 141, please refer to... Figures 2-4 It is evident that the three sets of support rollers 6 are movably arranged on the outer casing 2, ensuring that the rotating support rollers 6 do not provide resistance to the observation cylinder 3 when it rotates. To achieve controllable frictional resistance between the support rollers 6 and the observation cylinder 3, two support rollers 6 in one set are meshed and driven by a resistance-adjusting gear set 10, allowing the two support rollers 6 in one set to rotate synchronously. When the resistance-adjusting gear set 10 is unobstructed, the support rollers 6 can rotate along with the observation cylinder 3. When the resistance-adjusting gear set 10 is obstructed, it forces an increase in resistance between the rotating observation cylinder 3 and the support rollers 6, thereby restricting the rotation of the support rollers 6.

[0031] Furthermore, an adjusting piston 9 is movably mounted on the outer side of the outer casing 2, and a return spring 900 connects the adjusting piston 9 and the outer casing 2. The return spring 900 allows the adjusting piston 9 to move relatively away from the outer casing 2. On one hand, this moves the limiting gear 17 fixed to the end of the adjusting piston 9 relatively away from the adjusting gear set 10. On the other hand, the adjusting arm 16 fixed to the other end of the adjusting piston 9 will move relatively closer to the driving sleeve 14. It should be noted that, to reduce the contact resistance between the adjusting arm 16 and the driving sleeve 14, a roller is provided at the end of the adjusting arm 16, allowing the end of the adjusting arm 16 to rest against the outer side of the driving sleeve 14. When the adjusting piston 9 pushes the adjusting gear set 10 outward via the return spring 900, it will eventually touch the alarm bell 7 fixed to the support base 1. When the limiting gear 17 strikes the alarm bell 7, it forces the alarm bell 7 to sound. Figure 4 It can be seen that the bottom of the adjusting piston 9 is tightly connected to the liquid measuring baffle 8, and the liquid measuring baffle 8 is inserted into the medium in the water storage chamber 100. When the medium in the water storage chamber 100 is sufficient, when the adjusting piston 9 drives the liquid measuring baffle 8 to move, the liquid measuring baffle 8 will be affected by the medium resistance, which will relatively slow down the movement speed of the adjusting piston 9, thereby reducing the intensity of the impact of the limiting tooth row 17 on the alarm bell 7. Similarly, when the medium in the water storage chamber 100 is relatively small, the liquid measuring baffle 8 will no longer provide movement resistance, so that the limiting tooth row 17 can quickly impact the alarm bell 7.

[0032] In practical applications, when the drive motor 5 starts, the output shaft will drive the fan blade 11 and the grinding head 13 to rotate synchronously. If there is no material fed into the feeding pipe 4 at this time, the opening of the feeding pipe 4 is at its maximum. When the external airflow enters the outer casing 2, it can meet the airflow sucked in by the fan blade 11. At this time, the adjusting piston 9, under the elastic force of the reset push spring 900, causes the limiting gear rack 17 to move away from the outer casing 2 until the end of the limiting gear rack 17 touches the alarm bell 7. At this time, the limiting gear rack 17 will also release the rotation restriction on the adjusting gear set 10, allowing the observation cylinder 3 to rotate with low resistance. Under the contact between the drive pressure sleeve 14 and the observation cylinder 3, the support roller 6 rotates synchronously with the cleaning rod 141, thereby avoiding useless wear of the cleaning rod 141 when it is not working. Furthermore, as the driving sleeve 14 rotates the pressure-boosting protrusion 140, the pressure-boosting protrusion 140 pushes the adjusting arm 16, forcing the adjusting arm 16 to pull the adjusting piston 9 to compress the reset spring 900. The adjusting piston 9 then pulls the limiting gear rack 17 and the liquid measuring baffle 8 away from the alarm bell 7. When the pressure-boosting protrusion 140 moves away from the adjusting arm 16, under the elastic force of the reset spring 900, the limiting gear rack 17 will impact the alarm bell 7. Since the liquid measuring baffle 8 is located in the water storage chamber 100, if the medium in the water storage chamber 100 is sufficient, it can purify the air mentioned above. Moreover, the medium filling the water storage chamber 100 will increase the resistance to the movement of the liquid measuring baffle 8. This significantly reduces the strength of the limiting gear rack 17 when it approaches the alarm bell 7, making it less likely for the alarm bell 7 to produce an impact sound.

[0033] Similarly, if there is insufficient medium in the water storage chamber 100, when the adjusting piston 9 is pushed by the reset push spring 900, the movement resistance of the liquid measuring baffle 8 is relatively small, and the limiting toothed rack 17 will quickly strike the alarm bell 7. As the driving pressure sleeve 14 rotates continuously, the limiting toothed rack 17 will also periodically strike the alarm bell 7, thereby producing a sound to warn the operator that there is a lack of water in the water storage chamber 100 and it needs to be replenished.

[0034] Once the equipment is functioning normally, the material is inserted into the outer casing 2 through the feed pipe 4. Because the material blocks the feed pipe 4, the airflow area decreases, and the total amount of air drawn in by the fan blades 11 remains constant. Therefore, the gas velocity inside the feed pipe 4 increases relatively, further preventing fragments from splashing outwards. Furthermore, the obstruction of airflow into the feed pipe 4 causes a relative decrease in pressure within the outer casing 2. When the pressure inside the outer casing 2 decreases, the adjusting piston 9 tends to move towards the outer casing 2 until the limiting gear 17 abuts against the adjusting gear set 10, thus restricting the rotation of the adjusting gear set 10. At this point, the adjusting gear set 10 prevents the support roller 6 from rotating, increasing the resistance between the observation cylinder 3 and the support roller 6. As the drive pressure sleeve 14 continuously rotates following the grinding head 13, the cleaning rod 141 can brush the inside of the observation cylinder 3, preventing the observation cylinder 3 from rotating. As the pressure-boosting protrusion 140 comes into contact with the inner side of the observation cylinder 3, the contact resistance between them increases. At this point, the rotational intensity is greater than the motion resistance between the observation cylinder 3 and the support roller 6, causing the observation cylinder 3 to rotate. As the pressure-boosting protrusion 140 continues to rotate, the observation cylinder 3 will also rotate after cleaning, ensuring that the observation cylinder 3 remains transparent during grinding, facilitating observation by the operator.
