Description

Technical Field

[0001] The invention relates to the technical field of mortar stirring and pouring, and in particular to a small-sized mortar stirring and pouring equipment. Background Art

[0002] Mortar is a building material, mainly a mixture of cement, sand and water, and sometimes other additives. Mortar is used to firmly bond bricks, stones, blocks and other building materials together to form a solid wall or other structure.

[0028] The lower end of the upper cover plate 11 is a curved surface structure, and the lower end surface of the main body tube 1 is a curved surface structure corresponding to the lower end of the upper cover plate 11. The upper end of the upper cover plate 11 is fixedly connected with a connecting ring 312, and the upper end of the connecting ring 312 is fixedly connected with a second motor 311. The transmission shaft end of the second motor 311 is fixedly connected with a second transmission rod 313, and the side of the second transmission rod 313 is rotatably connected with a first electric telescopic rod 314 at a position close to the lower end. An accommodating groove 321 is opened through the upper cover plate 11. After the first electric telescopic rod 314 is rotated to a vertical state, the cross section of the second transmission rod 313 is smaller than the cross section of the accommodating groove 321.

[0029] A placement groove 315 is provided on the side surface of the telescopic end of the second transmission rod 313 at a position below the first electric telescopic rod 314, and a second electric telescopic rod 316 is fixedly connected in the placement groove 315, and a stopper 317 is fixedly connected to the telescopic end of the second electric telescopic rod 316, and a spring 318 is fixedly connected to the lower side surface of the first electric telescopic rod 314, and the other end of the spring 318 is fixedly connected to the telescopic end of the second transmission rod 313, and a second pressure sensor 320 is fixedly connected to the telescopic end of the first electric telescopic rod 314, and a fixing block 319 is fixedly connected to the end of the second pressure sensor 320.

During stirring, the first electric telescopic rod 314 contracts according to the value of the second pressure sensor 320 to ensure that the end of the fixed block 319 is always in contact with the inner wall of the main tube 1, thereby ensuring that the mortar at various positions in the main tube 1 can be completely stirred.

[0031] In this embodiment, a pushing mechanism 4 is provided on the side of the main tube 1 for pushing the main tube 1 through the upper cover plate 11 .

[0032] The pushing mechanism 4 includes two fixing sleeves 41 symmetrically arranged on the side of the main tube 1, and the upper ends of the two fixing sleeves 41 are respectively provided with third electric telescopic rods 42, and the telescopic ends of the two third electric telescopic rods 42 are respectively fixedly connected with connecting bodies 43, and the lower ends of the two connecting bodies 43 are fixedly connected with connecting rods 44, and the lower ends of the two connecting rods 44 are respectively fixedly connected with mounting plates 45, and the two mounting plates 45 are fixedly connected to the upper cover plate 11 by bolts.

[0033] Specifically, when the device is pushing and injecting mortar, the two third electric telescopic rods 42 are contracted, driving the upper cover plate 11 to squeeze the inside of the main tube 1 , and then the mortar in the main tube 1 comes out through the fixing ring 52 .

[0034] In this embodiment, a movable support mechanism 2 for supporting and moving the device is disposed on the side of the second fixed body 31 .

[0035] The mobile support mechanism 2 includes four first fixed bodies 21 symmetrically arranged on the side of the main tube 1, the lower ends of the four first fixed bodies 21 are respectively fixedly connected to the hydraulic telescopic rods 22, the lower ends of the four first fixed bodies 21 are respectively fixedly connected to the fixed shells 23, and the lower ends of the four fixed shells 23 are respectively fixedly connected to the anti-skid plate 26.

[0036] The telescopic ends of the four hydraulic telescopic rods 22 are respectively fixedly connected to connecting plates 24 , and the lower ends of the four connecting plates 24 are respectively rotatably connected to rollers 25 .

[0037] Specifically, the hydraulic telescopic rod 22 drives the roller 25 to contact the ground, which facilitates the movement of the device. When the specified position is reached, the hydraulic telescopic rod 22 is retracted to make the anti-slip plate 26 at the lower end of the fixed shell 23 contact the ground, which can increase the friction and prevent the device from being displaced during stirring.

[0038] In this embodiment, a bubble absorbing mechanism 5 for reducing bubbles in the mortar is disposed in the third fixed body 36 .

[0039] The bubble absorption mechanism 5 includes a mounting hole 51 that passes through the lower end of the main tube 1, the inside of the third fixed body 36 and the lower end of the second fixed body 31. A fixing ring 52 is fixedly connected in the mounting hole 51, and a mounting ring 55 is fixedly connected to the inner side surface of the fixing ring 52. An annular groove 54 is provided in the mounting ring 55. A plurality of one-way permeable rings 56 that communicate with the annular groove 54 are equidistantly arranged on the side surface of the mounting ring 55. A through hole 53 that communicates with the annular groove 54 is provided on the side surface of the fixing ring 52.

[0040] Specifically, when the mortar passes through the fixing ring 52, a plurality of one-way permeable rings 56 are arranged inside the fixing ring 52 through the mounting ring 55, and the plurality of one-way permeable rings 56 are communicated with the annular groove 54. When bubbles appear inside the mortar, the bubbles enter the one-way permeable ring 56 under the action of pressure and are discharged through the through hole 53.

[0041] When in use, the hydraulic telescopic rod 22 is extended, and the hydraulic telescopic rod 22 drives the roller 25 to contact the ground, which is convenient for moving the device. When it reaches the specified position, the hydraulic telescopic rod 22 is retracted to make the anti-slip plate 26 at the lower end of the fixed shell 23 contact the ground, which can increase the friction force and prevent the device from shifting during stirring. The two third electric telescopic rods 42 are extended to separate the upper cover plate 11 from the upper end of the main barrel 1, and then the end of the material delivery pipe of the mixer truck is placed into the main barrel 1 to inject material into the main barrel 1. When the injection is completed, the third electric telescopic rod 42 is retracted to align the upper end of the upper cover plate 11 with the upper end of the main barrel 1, and then the second motor 311 is started. The second motor 311 drives the second transmission rod 313 to rotate, and at the same time, the second transmission rod 313 slowly moves. By slowly extending, the first electric telescopic rod 314 on the side of the telescopic end of the second transmission rod 313 can rotate to stir the mortar in the main tube 1. During stirring, the first electric telescopic rod 314 contracts according to the value of the second pressure sensor 320 to ensure that the end of the fixed block 319 is always in contact with the inner wall of the main tube 1, ensuring that the mortar at various positions in the main tube 1 can be completely stirred. During stirring, the first motor 32 is started, and the first motor 32 drives the gear 34 to rotate through the first transmission rod 33. The gear 34 engages and drives the gear ring 37 to rotate, and the gear ring 37 drives the main tube 1 to rotate. The mortar in the main tube 1 can be completely stirred by centrifugal rotation, thereby improving the quality of the mortar.

[0042] When the device is pushing and injecting mortar, the two third electric telescopic rods 42 are contracted, driving the upper cover plate 11 to squeeze the inside of the main tube 1, and then the mortar in the main tube 1 comes out through the fixing ring 52. When the mortar passes through the fixing ring 52, a plurality of one-way permeable rings 56 are arranged inside the fixing ring 52 through the mounting ring 55. The plurality of one-way permeable rings 56 are connected to the annular groove 54. When bubbles appear in the mortar, the bubbles enter the one-way permeable rings 56 under the action of pressure and are discharged through the through hole 53. Therefore, most of the bubbles in the mortar can be removed, thereby improving the quality of the mortar during injection. At the same time as the mortar comes out, the plurality of first pressure sensors 39 can accurately measure the weight of the mortar coming out, and through the third electric telescopic rod 42 The expansion and contraction amount can be used to calculate the volume of the mortar that comes out, so that the density of the mortar that comes out of the main tube 1 at any time can be obtained. When the density of the mortar at a certain position does not meet the construction requirements after being placed for a long time, the device will alarm through the warning light 6 to remind workers that the quality of the mortar that comes out does not meet the requirements, so that this part of the mortar that comes out can be replaced, thereby improving the reliability of the device. When the upper cover 11 descends, the second transmission rod 313 slowly contracts, and the second electric telescopic rod 316 contracts at the same time. The first electric telescopic rod 314 rotates to a state horizontal with the second transmission rod 313 under the impact of the mortar, ensuring that the first electric telescopic rod 314 can enter the accommodating groove 321 and will not hinder the falling of the upper cover 11.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
