Description

Technical Field

[0001] This utility model relates to the field of concrete mixing tank technology, and in particular to a residual material cleaning device for commercial concrete mixing tanks. Background Technology

[0002] Concrete is an essential material in the construction industry. It often needs to be mixed before use. After use, the mixing tank often needs to be cleaned of the concrete adhering to its inner wall to facilitate the next use. The telescopic arm is located in the storage groove inside the connecting arm and has a telescopic sliding fit. When the cleaning scraper rotates and scrapes against the residue on the inner wall of the mixing tank, if it encounters a semi-hard concrete object, the cleaning scraper can drive the telescopic arm to retract and avoid direct hard contact by retracting it inside the storage groove when under pressure.

[0003] To avoid the danger of manual entry into the tank during the cleaning of residual materials in existing mixing tanks, water is sprayed onto the inner wall of the tank while the concrete is being mixed, and scraping components are used to scrape the inside, thus integrating the mixing and cleaning of concrete materials. However, the effect of cleaning the inner wall of the tank containing concrete materials by scraping is very small, because the concrete material comes into contact with the inner wall of the tank multiple times during mixing. When the mixing mechanism stops, the concrete material will splash onto the inner wall of the tank due to centrifugal force, and it will still need to be cleaned again. Therefore, its practicality is limited. To address this, we propose a residual material cleaning device for commercial concrete mixing tanks. Utility Model Content

[0004] The present invention mainly addresses the technical problems existing in the prior art by providing a residual material cleaning device for commercial concrete mixing tanks.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a residual material cleaning device for a commercial concrete mixing tank, comprising a mixing tank and an end cover. A guide cover is provided at the bottom of the mixing tank, and a protective cover is provided inside the guide cover. The protective cover is an elliptical hollow cover. The outer periphery of the protective cover is fixedly connected to the inner side of the guide cover via a support arm. A motor is installed inside the protective cover, and the outer periphery of the motor is supported and connected to the inner side of the protective cover via a fixing component. A drive shaft penetrating the protective cover is driven by the output shaft of the motor. Two sets of symmetrical connecting arms are installed around the drive shaft. A telescopic arm is slidably arranged inside the connecting arms via a receiving groove. A cleaning scraper is installed on one side of the telescopic arm. The cleaning scraper has an arc-shaped structure. A liquid storage box is installed on one side of the cleaning scraper. A nozzle is embedded in the surface of the liquid storage box. A pressure water tank is sleeved on the outside of the drive shaft. The pressure water tank is connected to the bottom of the liquid storage box via a liquid guide pipe.

[0006] Preferably, when the motor starts and drives the two sets of connecting arms to rotate via the drive shaft, the telescopic arm inside the connecting arm drives the cleaning scraper to rotate and scrape against the inside of the mixing tank for cleaning.

[0007] Preferably, after startup, the pressure water tank outside the drive shaft controls the nozzle on one side of the liquid storage box to spray and dissolve the residue inside the mixing tank through the liquid guide pipe.

[0008] Preferably, the lower end of the mixing tank is integrally formed with a connecting end, and the outer periphery of the connecting end and the inner side of the upper end of the guide cover are both provided with mutually matching threads. The upper end of the guide cover and the outer periphery of the connecting end are connected and fitted together by the threads.

[0009] Preferably, one side of the telescopic arm is engaged with a storage groove inside the connecting arm via a locking mechanism, and the storage groove is provided with a spring that is fixedly connected to the locking mechanism.

[0010] Preferably, when the drive shaft rotates and drives the cleaning scraper on one side of the telescopic arm to scrape and clean the residue inside the mixing tank, after the cleaning scraper is contacted by a hard object, the cleaning scraper controls the telescopic arm to be in a squeezed and telescopic state inside the storage groove.

[0011] This utility model provides a residual material cleaning device for commercial concrete mixing tanks. It has the following beneficial effects:

[0012] 1. This invention relates to a residual material cleaning device for a commercial concrete mixing tank. After the concrete material inside the mixing tank is processed and discharged, the end cap can be rotated and disassembled. The guide cover is then threadedly connected to the connecting end at the bottom of the mixing tank. The drive shaft can extend into the mixing tank. Upon motor startup, the motor drives the connecting arm to rotate via the drive shaft. Simultaneously, the pressure water tank is activated, supplying liquid to the storage box through a liquid guide pipe. A nozzle on one side of the storage box sprays water onto the contact surface between the cleaning scraper and the inner side of the mixing tank. The water can be clean water or a diluent solution, accelerating the dilution and decomposition of the concrete material. When the cleaning scraper on one side of the connecting arm scrapes against the inner wall of the mixing tank, it is dissolved and cleaned by the water sprayed directly opposite. As the water flows downwards with the cleaning scraper, it quickly discharges the fallen concrete residue, enabling rapid residual material cleaning without manual intervention, thus improving practicality.

[0013] 2. The residual material cleaning device for commercial concrete mixing tanks has a telescopic arm that slides and extends within a receiving groove inside the connecting arm. A clip on one side of the telescopic arm is connected to a spring support. When the cleaning scraper rotates and scrapes against the residual material inside the mixing tank, if it encounters a semi-hard concrete object, the cleaning scraper can retract and extend within the receiving groove under pressure to avoid direct hard contact, thereby reducing wear on the cleaning scraper and improving its service life.

A guide cover 4 is installed at the bottom of the mixing tank 1. A protective cover 5 is installed inside the guide cover 4. The protective cover 5 is an elliptical hollow cover. The outer periphery of the protective cover 5 is fixedly connected to the inner side of the guide cover 4 via a support arm 6. A motor 7 is installed inside the protective cover 5. The outer periphery of the motor 7 is supported and connected to the inner side of the protective cover 5 via a fixing component 8. A drive shaft 9, penetrating the protective cover 5, is driven by the output shaft of the motor 7. Two sets of symmetrical connecting arms 10 are installed around the drive shaft 9. A telescopic arm 12 is slidably installed inside the connecting arm 10 via a receiving groove 11. A cleaning scraper 13, which is arc-shaped, is installed on one side of the telescopic arm 12. The structure includes a liquid storage box 14 installed on one side of the cleaning scraper 13, with a nozzle 15 embedded in the surface of the liquid storage box 14. A pressure water tank 16 is installed on the outside of the drive shaft 9, and the pressure water tank 16 is connected to the bottom of the liquid storage box 14 through a liquid guide pipe 17. The lower end of the mixing tank 1 is integrally formed with a connecting end 3. The outer periphery of the connecting end 3 and the inner side of the upper end of the guide cover 4 are both provided with mutually matching threads 18. The upper end of the guide cover 4 and the outer periphery of the connecting end 3 are connected and installed by the threads 18. One side of the telescopic arm 12 is limited and engaged with the storage groove 11 inside the connecting arm 10 through a clamp 19. The storage groove 11 is provided with a spring 20 that is fixedly connected to the clamp 19.

[0025] Furthermore, when the motor 7 starts and drives the two sets of connecting arms 10 to rotate via the drive shaft 9, the telescopic arm 12 inside the connecting arm 10 drives the cleaning scraper 13 to rotate and scrape the inside of the mixing tank 1 for cleaning.

[0026] Furthermore, after the drive shaft 9 is started, the pressure water tank 16 outside the pressure water tank 16 controls the nozzle 15 on one side of the liquid storage box 14 to spray and dissolve the residual material inside the mixing tank 1 through the liquid guide pipe 17.

[0027] Furthermore, when the drive shaft 9 rotates and drives the cleaning scraper 13 on one side of the telescopic arm 12 to scrape and clean the residue inside the mixing tank 1, after the cleaning scraper 13 is in contact with a hard object, the cleaning scraper 13 controls the telescopic arm 12 to be in a squeezed and telescopic state inside the storage groove 11.

[0028] The working principle of this utility model:

[0029] After the concrete material inside the mixing tank 1 is processed and discharged, the end cover 2 can be rotated and disassembled, and the guide cover 4 can be threadedly connected to the connecting end 3 at the bottom of the mixing tank 1. The drive shaft 9 can extend into the mixing tank 1. After the motor 7 is started, the motor 7 can drive the connecting arm 10 to rotate through the drive shaft 9. At the same time, the pressure water tank 16 is started and supplies liquid to the storage box 14 through the liquid guide pipe 17. The nozzle 15 on one side of the storage box 14 sprays water on the contact surface between the cleaning scraper 13 and the inner side of the mixing tank 1. The water can be clean water or a certain diluent solution to accelerate the dilution and decomposition of the concrete material. At this time, when the cleaning scraper 13 on one side of the connecting arm 10 scrapes the inner wall of the mixing tank 1, it can be dissolved and cleaned by the water source sprayed from the opposite side. When the water source flows downward with the cleaning scraper 13, it can quickly discharge the fallen concrete residue, so as to quickly complete the residue cleaning without manual operation, thereby improving the practical effect.
