Description

Technical Field

[0001] The invention relates to the technical field of construction sites, in particular to a mortar removing device for a cement mortar containing bucket used in construction sites. Background Art

[0002] In construction projects, cement mortar is often used for wall construction or as an adhesive for block masonry materials. Cement mortar is a mixture of cement, sand and water. When cement mortar is used on construction sites, a bucket is often used to transfer the cement mortar. The bucket is generally made of rubber, which has a certain degree of softness and strong impact resistance, which can prevent it from falling and breaking. After using the bucket, it is usually necessary to clean it for the next use.

[0003] At present, after the existing cement mortar containing barrels are used, the residual mortar adhered to the inner wall will gradually solidify to form mortar blocks. If they are not cleaned in time, it will affect the normal operation of the mixing system and the feeding system. In addition, the residual mortar with high pH may cause erosion to the inner wall of the containing barrel and shorten its service life. The usual treatment method is to manually clean the inside of the cement mortar containing barrel with a high-pressure water gun and a brush head. However, manual cleaning is not only inefficient, but also difficult to ensure the cleaning effect, resulting in the need for secondary cleaning, which will increase the cleaning cost and affect the normal construction progress.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] Example 1: See Figures 1 to 7 , a mortar removing device for a cement mortar storage bucket used at a construction site, comprising a base plate 1 and a lifting electric push rod 2 fixedly installed at a position near the corner on the upper end surface of the base plate 1.

A washing and scraping component 4 is arranged below the solid mortar removing component 3, and the washing and scraping component 4 is fixedly installed in the middle of the upper end surface of the base plate 1; The solid mortar removing component 3 includes a lifting plate 31. The upper end of the lifting electric push rod 2 is fixedly connected with the lifting plate 31. A through groove is formed in the middle of the lifting plate 31. Rotating shafts 32 are symmetrically arranged on the middle part of the transverse inner side wall of the through groove. One of the rotating shafts 32 extends to the outside of the lifting plate 31 and is fixedly installed with a rocker arm 33. The adjacent ends of the two rotating shafts 32 are fixedly connected with a clamping unit 34. A solid mortar removing unit 35 is fixedly arranged at a position on the upper end surface of the lifting plate 31 and near one side edge of the through groove.

[0021] The clamping unit 34 includes a U-shaped plate 341. The adjacent ends of the two rotating shafts 32 are fixedly connected with the U-shaped plate 341.

A transmission gear 343 is fixedly connected to the lower end of the vertical shaft 342. A rectangular rack 344 is meshed with the side of the transmission gear 343. The rectangular rack 344 is fixedly connected to the telescopic end of a first electric push rod 345. The first electric push rod 345 is fixedly installed on the inner side wall of the U-shaped plate 341. A support plate 346 is fixedly connected to the upper end of the vertical shaft 342. Strip-shaped sliding grooves 347 are evenly formed on the upper end surface of the support plate 346 along its circumference. Clamping plates 349 are slidably installed in the strip-shaped sliding grooves 347 through clamping springs 348. Matching clamping pads 3491 are fixedly installed on the opposite side walls of the clamping plates 349.

[0022] The solid mortar removing unit 35 includes an L-shaped plate 351. An L-shaped plate 351 is fixedly arranged at a position on the upper end surface of the lifting plate 31 and near one side edge of the through groove. A rectangular sliding groove is formed in the side wall of the L-shaped plate 351. A sliding plate 352 is slidably arranged at the bottom of the rectangular sliding groove through a buffer spring 353. The middle of the sliding plate 352 is installed at the telescopic end of a second electric push rod 354. The lower end of the second electric push rod 354 is fixedly installed on the side wall of the L-shaped plate 351. A telescopic rod 355 is fixedly connected to the side wall of the sliding plate 352 close to the clamping unit 34. A tamping and cutting plate 356 is fixedly connected to the lower side of the end of the telescopic rod 355 far from the sliding plate 352. A limiting plate 357 is arranged on the side of the tamping and cutting plate 356. The upper end of the limiting plate 357 is fixedly installed on the sub-rod of the telescopic rod 355. A ball head rod 358 is fixedly connected to the upper side of the end of the telescopic rod 355 far from the sliding plate 352. The ball head end of the ball head rod 358 is made of a flexible material.

[0023] The transmission unit 36 ​​includes a lower pulley 361, which is fixedly installed on the rotating shaft 32 away from the rocker arm 33, and an upper pulley 363 is fixedly arranged on the mother rod of the telescopic rod 355. The upper pulley 363 and the lower pulley 361 are connected by a transmission belt 362. The first arc baffle 3611 is fixedly installed on the outer side of the lower half of the lower pulley 361, and the second arc baffle 3631 is fixedly installed on the outer side of the upper half of the upper pulley 363.

[0024] During the specific operation, the used cement mortar holding bucket is manually placed on the middle part of the upper end of the support plate 346, and the edge of the cement mortar holding bucket is pressed downward, so that the clamping plate 349 moves away from each other in the strip slide groove 347, and the clamping spring 348 is stretched at the same time. When the lower end surface of the cement mortar holding bucket and the upper end surface of the support plate 346 are in conflict, the pressing of the cement mortar holding bucket is stopped. At this time, the reaction force of the clamping spring 348 will act on the clamping plate 349, and the setting of the pad 3491 can cooperate with the clamping plate 349, thereby increasing the friction between the clamping plate 349 and the outer wall of the cement mortar holding bucket, which is conducive to fixing and clamping the cement mortar holding bucket to be cleaned; The second electric push rod 354 is started, and the slide plate 352, the telescopic rod 355, the tamping and cutting plate 356 and the limit plate 357 are driven by the second electric push rod 354 to continuously reciprocate up and down. When the tamping and cutting plate 356 moves downward, the lower end of the tamping and cutting plate 356 will contact the inner wall of the cement mortar holding barrel, and then the solidified mortar blocks on the inner wall will be tamped and crushed. At the same time, the lower end of the limit plate 357 will be attached to the outer wall of the cement mortar holding barrel, and the dirt on the outer wall of the cement mortar holding barrel will be removed during the subsequent downward movement. The inner diameter of the cement mortar holding barrel gradually decreases from top to bottom, so the setting of the telescopic rod 355 can make the tamping and cutting plate 356 move left and right adaptively, thereby improving the smoothness of crushing the solidified mortar blocks. During the working process of the tamping and cutting plate 356, the limit plate 357 and the tamping and cutting plate 356 move synchronously. Since the cement mortar holding barrel is made of rubber, the limit plate 357 will cause the side wall of the cement mortar holding barrel to be slightly deformed, and the deformation can act on the solidified mortar blocks on its inner wall, thereby making it more conducive to crushing and falling off; During the above process, the first electric push rod 345 is started, and the rectangular rack 344 is driven to move back and forth by the first electric push rod 345. Under the meshing action of the transmission gear 343, the vertical shaft 342 drives the support plate 346 and the clamped cement mortar holding bucket to reciprocate, so that the broken solidified mortar blocks on the inner wall are completely removed; Start the lifting electric push rod 2, and drive the solid slurry removal component 3 to move upward as a whole for an appropriate distance through the lifting electric push rod 2. The specific limit of this distance is that the cement mortar holding barrel will not contact the washing and scraping component 4 during the process of turning over one circle. Then, the rocker arm 33 is manually rotated to drive the rotating shaft 32 to rotate 18 degrees, thereby driving the clamping unit 34 and the cement mortar holding barrel after fixed clamping to turn over 18 degrees. At this time, the opening of the cement mortar holding barrel faces downward, and the solidified mortar blocks that fall off from the inside will also fall downward and detach from the cement mortar holding barrel, and the rotating shaft 3 During the rotation process, the lower pulley 361 is also driven to rotate, and the upper pulley 363 is also rotated under the action of the transmission belt 362, and the ball head rod 358 moves to a position perpendicular to the lifting plate 31, and the shaped plate 341 also moves from the opening downward to the opening upward. Then, the second electric push rod 354 continues to drive the slide plate 352 to reciprocate up and down. At this time, the ball head rod 358 continuously strikes the shaped plate 341, thereby causing the clamping unit 34 to vibrate, which is conducive to improving the efficiency of the mortar blocks in the cement mortar holding bucket falling off.

[0025] It should be noted that the first arc baffle 3611 and the second arc baffle 3631 are provided to prevent the transmission belt 362 from detaching from the lower pulley 361 and the upper pulley 363 when the upper pulley 363 reciprocates up and down with the telescopic rod 355, thereby ensuring the stability of subsequent operation.

[0026] Embodiment 2: The technical solution is basically the same as that of Embodiment 1, see Figure 1 to Figure 2 as well as Figures 8 to 11 The difference is that: the washing and scraping component 4 includes a driving motor 41, a driving motor 41 is fixedly installed in the middle of the upper end surface of the substrate 1, a waterproof shell 42 is arranged on the outside of the driving motor 41, and nozzles 43 are evenly installed on the upper end surface of the waterproof shell 42 along its circumference, and the lower end of the nozzle 43 is connected to the external water supply pipe, the output shaft of the driving motor 41 extends to the top of the waterproof shell 42 and is fixedly connected to a convex shell 44, a flower-shaped groove 45 is provided on the inner wall of the upper end of the convex shell 44, a flower-shaped shaft 46 is installed in the flower-shaped groove 45, a top wiping plate 47 is fixedly connected to the upper end of the flower-shaped shaft 46, and a scraping unit 48 is fixedly connected to the lower end of the flower-shaped shaft 46.

[0027] The scraping unit 48 includes a connecting rod 481, the lower end of the flower-shaped shaft 46 is fixedly connected to the connecting rod 481, the lower end of the connecting rod 481 is fixedly connected to an extrusion block 482, the extrusion block 482 is a cylindrical structure that is thick at both ends and thin in the middle, an extrusion spring 483 is installed between the lower end of the extrusion block 482 and the bottom of the convex shell 44, and a ball head sliding shaft 484 is evenly penetrated through the side wall of the convex shell 44 along its circumference, the ball head end of the ball head sliding shaft 484 is slidably fitted with the extrusion block 482 and a return spring 485 is installed between it and the side wall of the convex shell 44, and the end of the ball head sliding shaft 484 extending out of the convex shell 44 is hinged with a scraping plate 486.

[0028] During specific operation, the lifting electric push rod 2 is started again, and the solid slurry removal component 3 is driven to move downward as a whole through the lifting electric push rod 2, so that the cement mortar holding barrel and the top wiping plate 47 conflict with each other and drive the top wiping plate 47 to continue to move downward, and the top wiping plate 47 drives the connecting rod 481 and the extrusion block 482 to move downward. At this time, the extrusion spring 483 is compressed, and the mutual cooperation between the extrusion block 482 and the ball head sliding shaft 484 drives the ball head sliding shaft 484 to move toward the outside of the convex shell 44, so that the scraper plate 486 is adaptively attached to the inner wall of the cement mortar holding barrel. At this time, the lifting electric push rod 2 The rod 2 stops running and the driving motor 41 is started. The driving motor 41 drives the convex shell 44 to rotate, and at the same time drives the flower-shaped shaft 46, the top wiping plate 47 and the scraper plate 486 to rotate. The rotation of the top wiping plate 47 can clean the top of the cement mortar holding barrel, and the rotation of the scraper plate 486 can further clean the inner wall of the cement mortar holding barrel. The high-pressure water flow sprayed by the nozzle 43 can clean the inside of the cement mortar holding barrel, and the sewage will automatically fall downwards. Due to the setting of the waterproof shell 42, the sewage will not affect the normal operation of the driving motor 41.

[0029] The working principle of the present invention when in use: One: manually place the used cement mortar holding bucket on the middle of the upper end of the support plate 346, press the edge of the cement mortar holding bucket downward, so that the clamping plate 349 moves away from each other in the strip slide groove 347, and the clamping spring 348 is stretched at the same time. When the lower end surface of the cement mortar holding bucket and the upper end surface of the support plate 346 collide with each other, stop pressing the cement mortar holding bucket. At this time, the reaction force of the clamping spring 348 will act on the clamping plate 349. The setting of the pad 3491 can cooperate with the clamping plate 349, thereby increasing the friction between the clamping plate 349 and the outer wall of the cement mortar holding bucket, which is conducive to fixing and clamping the cement mortar holding bucket to be cleaned; Second: Start the second electric push rod 354. Drive the slide plate 352, the telescopic rod 355, the ramming and cutting plate 356 and the limiting plate 357 to continuously perform up and down reciprocating motions through the second electric push rod 354. When the ramming and cutting plate 356 moves downward, the lower end of the ramming and cutting plate 356 will contact the inner wall of the cement mortar storage barrel, and then ram and crush the mortar blocks solidified on its inner wall. At the same time, the lower end of the limiting plate 357 will fit on the outer wall of the cement mortar storage barrel, and clean the dirt on the outer wall of the cement mortar storage barrel during the subsequent downward movement. Since the inner diameter of the cement mortar storage barrel gradually decreases from top to bottom, the setting of the telescopic rod 355 can enable the ramming and cutting plate 356 to move left and right adaptively, thereby improving the smoothness of crushing the solidified mortar blocks. During the working process of the ramming and cutting plate 356, the limiting plate 357 and the ramming and cutting plate 356 move synchronously. Since the cement mortar storage barrel is made of rubber material, the limiting plate 357 will cause a slight deformation of the side wall of the cement mortar storage barrel, and this deformation can act on the mortar blocks solidified on its inner wall, which is more conducive to their crushing and falling off; Third: During the above process, start the first electric push rod 345. Drive the rectangular rack 344 to perform left and right reciprocating motions through the first electric push rod 345. Under the meshing action of the transmission gear 343, the vertical shaft 342 will drive the support disc 346 and the clamped and fixed cement mortar storage barrel to perform reciprocating rotations, so as to comprehensively remove the crushed solidified mortar blocks on its inner wall; Fourth: After step three is completed, the second electric push rod 354 drives the slide plate 352, the telescopic rod 355, the ramming and cutting plate 356 and the limiting plate 357 to reset upward. Then start the lifting electric push rod 2. Drive the solid mortar removal assembly 3 to move upward an appropriate distance through the lifting electric push rod 2. The specific limit of this distance is that the cement mortar storage barrel will not contact the washing and scraping assembly 4 during one revolution. Then manually rotate the rocker arm 33 to drive the rotating shaft 32 to rotate 18 degrees, thereby driving the clamping unit 34 and the clamped and fixed cement mortar storage barrel to rotate 18 degrees. At this time, the opening of the cement mortar storage barrel faces downward, and the fallen solidified mortar blocks inside it will also fall downward and脱离 the cement mortar storage barrel. And the rotating shaft 32 will also drive the lower belt pulley 361 to rotate during the rotation process. Under the action of the transmission belt 362, the upper belt pulley 363 will also rotate. The ball head rod 358 moves to a position perpendicular to the lifting plate 31, and the C-shaped plate 341 also moves from the opening facing downward to the opening facing upward. Then the second electric push rod 354 continues to drive the slide plate 352 to perform up and down reciprocating motions. At this time, the ball head rod 358 will continuously knock on the C-shaped plate 341, so as to vibrate the clamping unit 34, which is beneficial to improving the efficiency of the mortar blocks falling off in the cement mortar storage barrel; Five: After the end of step four, the lifting electric push rod 2 is started again, and the solid slurry removal component 3 is driven to move downward as a whole through the lifting electric push rod 2, so that the cement mortar holding barrel and the top wiper plate 47 conflict with each other and drive the top wiper plate 47 to continue to move downward, and the top wiper plate 47 drives the connecting rod 481 and the extrusion block 482 to move downward. At this time, the extrusion spring 483 is compressed, and the ball head slide shaft 484 is driven to move toward the outside of the convex shell 44 through the mutual cooperation of the extrusion block 482 and the ball head slide shaft 484, so that the scraper plate 486 is adaptively attached to the inner wall of the cement mortar holding barrel. At this time, the lifting electric push rod 2 The push rod 2 stops running, and the driving motor 41 is started. The driving motor 41 drives the convex shell 44 to rotate, and at the same time drives the flower-shaped shaft 46, the top wiping plate 47 and the scraper plate 486 to rotate. The top wiping plate 47 rotates to clean the top of the cement mortar holding barrel, and the scraper plate 486 rotates to further clean the inner wall of the cement mortar holding barrel. The high-pressure water flow sprayed by the nozzle 43 cleans the inside of the cement mortar holding barrel, and the sewage automatically falls downward. Due to the setting of the waterproof shell 42, the sewage will not affect the normal operation of the driving motor 41. Six: When the cleaning process is completed, the lifting electric push rod 2 drives the solid slurry removal component 3 to move upward as a whole again, and the manual rotation of the rocker arm 33 drives the rotating shaft 32 and the clamping unit 34 to flip over again 18. At this time, the opening of the cement mortar holding barrel faces upward, and the cement mortar holding barrel is manually pulled up to separate it from the clamping unit 34, and then a new cement mortar holding barrel that needs to be cleaned is replaced to complete the continuous cleaning operation.
