Description

Technical Field

[0001] The invention belongs to the technical field related to grinding machines, and in particular relates to a material rust removal and grinding machine used in construction sites. Background Art

[0002] Rust removal and grinding machines for construction site materials play a vital role in the construction industry and are indispensable professional equipment. With their powerful functions, these machines can quickly remove rust and dirt from the surface of construction materials, thereby significantly improving construction efficiency and ensuring project progress and quality.

[0003] In the actual construction process, especially when the ends of the materials need to be welded, such as the brackets of doors, windows or railings, the application of rust removal and grinding machines is particularly critical. Since the presence of rust will seriously affect the welding quality and may shorten the subsequent service life, the ends of the materials must be finely ground in advance before welding. This process requires not only the removal of rust, but also the flatness of the end surface, laying the foundation for high-quality welding work.

[0004] At present, the grinding of material end faces is mostly carried out using desktop grinding machines. However, in actual operation, the flying sparks and metal fragments generated during the grinding process bring many safety hazards. These flying objects will not only rapidly deteriorate the operating environment, but also increase the risk of operators inhaling fly ash, which will cause harm to the body; at the same time, since operators need to pay close attention to the grinding area, flying fragments can easily fly into the eyes or other sensitive parts, causing serious damage. Summary of the invention

[0005] The present invention provides a material rust removal and grinding machine for construction sites, which has the advantages of enclosure protection and air purification, and is used to solve the problem in the above background technology that sparks and fragments generated during the grinding process are likely to cause damage to the operator's body.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a material rust removal and grinding machine for construction sites, comprising: a supporting base, on the surface of which is mounted an outer shell sleeve, and an observation tube is movably mounted on the end of the outer shell sleeve; a driving motor, mounted on the end of the outer shell sleeve, and the output shaft of the driving motor can drive the grinding head and fan blades located inside the outer shell sleeve to rotate; a feeding pipe, fixed on the end of the outer shell sleeve.

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

[0008] Furthermore, a support roller for clamping the observation tube is movably installed on the inner side of the outer shell, and a transmission gear set movably installed on the inner side of the outer shell realizes synchronous rotation of the grinding head and the driving motor. A driving pressure sleeve is fixed on the grinding head, and a cleaning rod is fixedly installed on the surface of the driving pressure sleeve.

[0009] Furthermore, three groups of support rollers are provided, the three groups of support rollers are arranged at equal angles, and the number of support rollers in each group is two.

[0010] Furthermore, a boosting bump is arranged on the outer side of the driving sleeve.

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

[0012] Furthermore, two support rollers in one group are meshed and driven by a resistance-adjusting gear set, an adjusting piston is movably installed on the outside of the outer shell, and a reset spring is connected between the adjusting piston and the outer shell; a limited-motion 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 supporting base, and a liquid measuring baffle is fastened to the bottom of the adjusting piston. Beneficial Effects

[0014] The present invention provides a material rust removal and grinding machine designed for construction sites. Its unique design is that the grinding head is fully and safely surrounded by a solid outer shell and a transparent observation tube. This design not only ensures safety during operation, but also greatly improves the efficiency and quality of grinding operations. When fine grinding is required on the ends of building materials, such as pre-treatment of door and window frames or railing brackets, the grinding head rotates efficiently under the action of a driving force to quickly remove rust and grind the surface of the material.

[0015] In this process, the transparent observation tube plays a vital role. It not only allows the operator to clearly observe the real-time status of the grinding area to ensure the accuracy and uniformity of grinding, but also its solid structure effectively blocks the metal fragments and fly ash generated during the grinding process from flying outward, thus greatly reducing the potential threat to the operator and the surrounding environment.

[0016] Furthermore, the rust removal grinder is also equipped with high-speed rotating fan blades. While the grinding head is grinding, the fan blades start to work, forcefully sucking the external airflow into the inner cavity of the outer shell, and finally, the airflow with fly ash will be guided into the built-in water storage chamber. As a key link 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 will be effectively adsorbed and settled by the medium, thereby achieving efficient treatment of the fly ash. This process not only prevents dust from flying around the construction site, but also significantly improves the operating environment and ensures the respiratory health of the operators.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figure 1 It can be seen that the support base 1 can be installed to the desired position using the positioning holes at the four corners. The outer shell 2 is fastened to the top of the support base 1 by bolts, and combined with Figure 2 It can be seen that an observation tube 3 is movably mounted at the end of the outer shell 2 . The observation tube 3 is transparent, so that the operator can observe the grinding state of the material inside the outer shell 2 in real time by using the observation tube 3 .

[0021] The driving motor 5 is fastened to the end of the outer shell 2. The output shaft of the driving motor 5 can drive the grinding head 13 located inside the observation tube 3 to rotate. The rotating grinding head 13 can grind the material to remove burrs and rust at the end of the material. Furthermore, in order to prevent the grinding debris from splashing outward, the end of the outer shell 2 is provided with a feeding pipe 4 fastened by bolts. The feeding pipe 4 not only determines the feeding position of the material, but also uses the shielding of the feeding pipe 4 to further prevent the grinding debris from splashing outward.

[0022] Combination Figure 2It can be clearly seen that the fan blade 11 is fastened to the output shaft of the driving motor 5. When the driving motor 5 drives the grinding head 13 to rotate, the fan blade 11 rotates synchronously, so that the external airflow is sucked into the inner cavity of the outer shell 2 through the feeding pipe 4. On the one hand, it prevents the fly ash generated by grinding from scattering outward. On the other hand, the airflow inside the feeding pipe 4 always has a tendency to flow into the inner cavity of the outer shell 2, further reducing the kinetic energy of the fragments when they splash from the inside of the feeding pipe 4, and reducing the possibility of the fragments flying out of the feeding pipe 4. For the treatment of fly ash and fragments, combined with Figure 2 It can be known that a water storage chamber 100 for storing liquid medium is opened on the inner side of the support base 1, and the liquid medium is preferably water. When the fan blade 11 sucks the external airflow into the inner cavity of the outer shell 2, the exhaust pipe 15 fastened to the outside of the outer shell 2 can flow the airflow into the liquid medium in the water storage chamber 100, thereby achieving absorption and precipitation of fly ash.

[0023] In actual application, the driving motor 5 is connected to the power supply, forcing the driving motor 5 to simultaneously drive the fan blade 11 and the grinding head 13 to rotate synchronously. The operator inserts the end of the material to be ground from the feeding pipe 4, so that the rotating grinding head 13 grinds the end of the material.

[0024] During the grinding process, the state of material grinding can be observed in real time by using the observation tube 3. At the same time, the fan blade 11 rotates to make the external air flow flow into the inner cavity of the outer shell 2 through the feeding pipe 4, so that the fly ash and debris generated by the grinding are blown out to the exhaust pipe 15. The exhaust pipe 15 blows the air flow with fly ash into the water storage chamber 100 filled with liquid medium, so as to clean the fly ash. This method not only avoids the harm of fly ash and debris to the operator, but also can automatically purify the air and collect impurities during the grinding process, greatly improving the cleanliness of the environment.

[0025] Embodiment 2 is a further improvement on Embodiment 1. Since the observation tube 3 is made of transparent material, after a long period of operation, impurities such as fly ash will adhere to the inside of the observation tube 3, which will cause the observation tube 3 to be blocked by the impurities and the grinding state of the material inside the outer shell 2 cannot be seen clearly. In order to solve this problem, please refer to Figure 2-Figure 4 It can be clearly seen that a support roller 6 for clamping the observation tube 3 is movably installed inside the outer shell 2. There are three groups of support rollers 6, and the three groups of support rollers 6 are arranged at equal angles to achieve stable clamping of the observation tube 3. There are two support rollers 6 in each group, and the two support rollers 6 are respectively located at the inner and outer sides of the observation tube 3, so as to ensure that the support rollers 6 firmly clamp the observation tube 3.

[0026] from Figure 4It can be known that a transmission gear set 12 is movably mounted inside the outer shell 2, and the transmission gear set 12 is composed 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 two transmission gears are meshed and driven to enable the grinding head 13 to rotate. Figure 3 It can be clearly seen that due to the intervention of the transmission gear set 12, the grinding head 13 and the observation tube 3 are not coaxial. On this basis, the driving sleeve 14 is coaxially tightened with the grinding head 13, and a cleaning rod 141 is fixedly installed on the surface of the driving sleeve 14. When the driving sleeve 14 rotates with the grinding head 13, the cleaning rod 141 can wipe and scrub the inner side of the observation tube 3, thereby ensuring the transparency of the observation tube 3.

[0027] In actual application, the driving motor 5 drives the fan blade 11 and the grinding head 13 to rotate synchronously, so as to realize the grinding work described in the first embodiment. In addition, when the grinding head 13 drives the driving pressing sleeve 14 to rotate synchronously, the rotation resistance of the observation tube 3 increases due to the clamping of the supporting roller 6. When the driving pressing sleeve 14 drives the cleaning rod 141 to move inside the observation tube 3, the cleaning rod 141 is used to wipe the inside of the observation tube 3, so as to ensure that the observation tube 3 can be more transparent and avoid observation by the operator.

[0028] On this basis, combined with Figure 3 It can be seen that a boosting bump 140 is provided on the outside of the driving sleeve 14. When the driving sleeve 14 rotates to contact the inside of the observation tube 3, the contact strength between the observation tube 3 and the driving sleeve 14 is increased, forcing the observation tube 3 to rotate synchronously with the driving sleeve 14, thereby rotating the cleaned observation tube 3 upward for easy observation by the operator. The intermittent rotation of the observation tube 3 forces the cleaning rod 141 to fully clean the inside of the observation tube 3, ensuring that the operator can use the observation tube 3 to observe the degree of material grinding.

[0029] As a supplement to the second embodiment, in order to further clean the observation tube 3, Figure 2 and Figure 5 It can be clearly seen that a connecting groove 200 for connecting the inner cavity of the outer shell 2 and the water storage cavity 100 is provided at the bottom of the outer shell 2. The connecting groove 200 can allow 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 presence of 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] The third embodiment is a further improvement on the second embodiment. In actual application, when the grinding head 13 is not grinding, the cleaning rod 141 will still wipe the observation tube 3. Since the friction between the two is used for cleaning, the long-term friction will cause the cleaning rod 141 to be worn. In order to reduce the useless wear of the cleaning rod 141, please refer to Figure 2-Figure 4 It can be clearly seen that the three groups of support rollers 6 are movably arranged on the outer shell 2, so that when the observation tube 3 rotates, the rotating support rollers 6 will not provide resistance to the observation tube 3. In order to achieve controllable friction resistance between the support rollers 6 and the observation tube 3, two support rollers 6 in one group are meshed and driven by the resistance adjustment gear set 10, so that the two support rollers 6 in one group can rotate synchronously. When the resistance adjustment gear set 10 is not blocked, when the observation tube 3 rotates, the support rollers 6 can rotate with it. When the resistance adjustment gear set 10 is blocked, the resistance between the rotating observation tube 3 and the support rollers 6 will be forced to increase, thereby limiting the rotation of the support rollers 6.

[0031] Furthermore, an adjusting piston 9 is movably installed on the outside of the outer shell 2, and a reset spring 900 is connected between the adjusting piston 9 and the outer shell 2. The reset spring 900 can make the adjusting piston 9 relatively away from the outer shell 2. On the one hand, the limit gear row 17 fixed at the end of the adjusting piston 9 is relatively away from the resistance adjusting gear set 10. On the other hand, the adjusting arm 16 fixed at the other end of the adjusting piston 9 will be relatively close to the driving sleeve 14. It should be noted that in order 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. The roller can make the end of the adjusting arm 16 stick to the outer side of the driving sleeve 14. When the adjusting piston 9 pushes the resistance adjusting gear set 10 to move outward through the reset spring 900, it will eventually touch the alarm bell 7 fixed on the supporting base 1. When the limit gear row 17 hits the alarm bell 7, the alarm bell 7 is forced to make a sound. Figure 4 It can be seen that a liquid measuring baffle 8 is fastened to the bottom of the adjusting piston 9, 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, the adjusting piston 9 drives the liquid measuring baffle 8 to move. The liquid measuring baffle 8 is affected by the resistance of the medium and will relatively slow down the movement speed of the adjusting piston 9, thereby reducing the intensity of the limit gear row 17 hitting 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 limit gear row 17 can quickly hit the alarm bell 7.

[0032] In specific application, when the driving motor 5 is started, 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 tube 4 at this time, the feeding tube 4 is at its largest opening at this time. When the external airflow is input into the outer shell 2, it can meet the airflow inhaled by the fan blade 11. At this time, the regulating piston 9 moves the limit gear row 17 away from the outer shell 2 under the elastic force of the reset push spring 900, until the end of the limit gear row 17 hits the alarm bell 7. The limit gear row 17 will also release the rotation restriction of the resistance adjustment gear set 10 at this time, so that the observation tube 3 can rotate with low resistance. Under the contact between the driving pressure sleeve 14 and the observation tube 3, the support roller 6 rotates synchronously with the cleaning rod 141, so as to avoid useless wear of the cleaning rod 141 when it is not working. Moreover, as the driving sleeve 14 drives the boosting protrusion 140 to rotate, the boosting protrusion 140 will push the regulating arm 16, forcing the regulating arm 16 to pull the regulating piston 9 to compress the reset spring 900, and the regulating piston 9 pulls the limit gear row 17 and the liquid measuring baffle 8 to move away from the alarm bell 7. When the boosting protrusion 140 moves away from the regulating arm 16, the limit gear row 17 will hit the alarm bell 7 under the elastic force of the reset spring 900. Since the liquid measuring baffle 8 exists in the water storage chamber 100, if the medium in the water storage chamber 100 is sufficient, the air mentioned above can be purified, and the medium filled in the water storage chamber 100 will increase the movement resistance of the liquid measuring baffle 8. The strength of the limit gear row 17 when it approaches the alarm bell 7 is greatly reduced, and the alarm bell 7 is not easy to produce a collision sound.

[0033] Similarly, if there is a state of 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 limit gear row 17 will quickly hit the alarm bell 7. As the driving sleeve 14 continues to rotate, the limit gear row 17 will also periodically hit the alarm bell 7, thereby generating 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] When the equipment is normal, after the material is inserted into the outer shell 2 through the feed pipe 4, the air circulation area will be reduced because the material blocks the feed pipe 4, and the total amount of air sucked by the fan blade 11 is always constant. Therefore, the gas flow rate inside the feed pipe 4 will increase relatively, further preventing the debris from splashing outward. In addition, the airflow input of the feed pipe 4 is blocked, which will cause the pressure in the inner cavity of the outer shell 2 to decrease relatively. When the pressure in the inner cavity of the outer shell 2 decreases relatively, the regulating piston 9 will tend to move toward the outer shell 2 until the limit gear row 17 hits the resistance regulating gear set 10, thereby limiting the rotation of the resistance regulating gear set 10. At this time, the resistance regulating gear set 10 makes the support roller 6 unable to rotate, and the movement resistance between the observation tube 3 and the support roller 6 increases. As the driving pressure sleeve 14 continues to rotate with the grinding head 13, the cleaning rod 141 can brush the inside of the observation tube 3, and the observation tube 3 cannot rotate at this time. As the boosting protrusion 140 contacts the inner side of the observation tube 3, the contact resistance between the two increases. At this time, the rotation intensity is greater than the movement resistance between the observation tube 3 and the support roller 6, and the observation tube 3 rotates. As the boosting protrusion 140 rotates continuously, the observation tube 3 will also rotate after cleaning, ensuring that the observation tube 3 is always transparent during grinding, which is convenient for the operator to observe.
