Description

Technical Field

[0001] The present invention relates to the technical field of mortar mixing, and particularly to a stirring device for lightweight aggregate modified special mortar. Background Art

[0002] In the field of lightweight aggregate modified special mortar production, the performance of the stirring device directly affects the quality of the mortar.

[0003] The Chinese Patent Network discloses a construction process for making concrete split stones and its raw material stirring device, with the patent publication number "CN110014501B". It is mainly used for stirring and crushing raw materials to facilitate filtration and screening; efficiently screening and discharging the crushed raw materials, so that the raw materials remaining on the upper layer of the filter screen continue to be crushed; facilitating the dropping of the materials in the filter holes of the filter screen to prevent blockage. However, when this device is used for stirring lightweight aggregate mortar, the key component in the mortar, the lightweight aggregate, has the remarkable characteristics of low density and light texture, and its shape shows a high degree of irregularity. This unique physical property makes it difficult for the lightweight aggregate to be mixed with other conventional raw materials during the stirring process, and when this device discharges materials of the adhesive material like mortar, it is easy to cause mortar adhesion, thus driving material discharge blockage.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0035] Embodiment 1:

[0036] Refer to Figure 1 - Figure 6 、 One A stirring device for a lightweight aggregate modified special mortar, including a frame body 1, an oscillation assembly, a material discharging assembly, and an auxiliary feeding assembly:

[0037] A motor mount 2 is fixedly connected to the side wall of the frame body 1. A motor 3 is fixedly installed at the upper end of the motor mount 2. The output shaft of the motor 3 is fixedly connected to a first pulley 4. The first pulley 4 is connected to a second pulley 6 through a belt 5. The second pulley 6 is fixedly connected to a rotating shaft 7.

[0038] The oscillation assembly is used to assist the stirring assembly in stirring the mortar.

[0039] The blanking assembly is used to assist in the blanking of the well-stirred slurry.

[0040] The auxiliary feeding assembly is used to assist in the feeding of raw materials.

[0041] One end of the rotating shaft 7 away from the second pulley 6 is connected to a gearbox 8. The gearbox 8 is connected to a rotating shaft 9. A roller 10 is fixedly connected to the outer wall of the rotating shaft 9. Two fixed bearings 102 are fixedly connected to the frame body 1. The two fixed bearings 102 are symmetrically arranged. The rotating shaft 9 sequentially passes through the two fixed bearings 102. The rotating shaft 9 is rotatably connected to the two fixed bearings 102. Two groups of oscillation rods 11 are fixedly connected to the outer wall of the roller 10. The gearbox 8 is fixedly connected to the outer wall of the frame body 1. The oscillation assembly consists of a vibration box 14, two groups of return springs 103, and two cross bars 101. The two cross bars 101 are fixedly connected to the frame body 1. The two cross bars 101 are symmetrically arranged. A chute 104 is provided in the cross bar 101. Two sliders 105 are respectively fixedly connected to both ends of the side wall of the vibration box 14. The two sliders 105 are respectively slidably connected in the two chutes 104. One end of the return spring 103 is fixedly connected to the vibration box 14, and the other end is fixedly connected to the frame body 1. The two groups of return springs 103 are symmetrically arranged.

[0042] It should be noted that the inside of the gearbox 8 usually consists of a series of gears with different numbers of teeth. These gears mesh with each other to form different transmission ratios. The gearbox is a commonly used working component for those in the field. In this equipment, the rotating shaft 7 is connected to the input shaft of the gearbox 8. A driving gear is fixed on the input shaft. When the input shaft drives the driving gear to rotate, the driving gear meshes with driven gears with different numbers of teeth, so as to achieve different rotational speed outputs. The output shaft of the gearbox 8 is connected to the rotating shaft 9. The power after speed change is transmitted to the rotating shaft 9 through the output shaft, and then drives the roller 10 and the oscillation rods 11 to carry out the stirring work.

[0043] A first impact block 1401 is fixedly connected to the upper end of the vibration box 14. A second impact block 1402 is fixedly connected to the upper end of the vibration box 14. The first impact block 1401 and the second impact block 1402 are symmetrically arranged. Both the first impact block 1401 and the second impact block 1402 are provided with inclined angles. It should be noted that the inclined angles provided on the first impact block 1401 and the second impact block 1402 have opposite opening angles on the same axis.

[0044] In this embodiment, the motor 3 is turned on. The output shaft of the motor 3 drives the first pulley 4 to rotate. Through the transmission of the belt 5, the second pulley 6 rotates, and then drives the rotating shaft 7 to rotate. The rotating shaft 7 is connected to the gearbox 8, and the power is transmitted to the gearbox 8. The output shaft of the gearbox 8 is connected to the rotating shaft 9. The power after speed change is transmitted to the rotating shaft 9 through the output shaft. The rotating shaft 9 drives the drum 10 to start rotating, and the two sets of oscillating rods 11 fixed on the outer wall of the drum 10 rotate synchronously. As the drum 10 continues to rotate, when the oscillating rod 11 rotates to contact the first impact block 1401 at the upper end of the vibration box 14, an impact force will be applied to the first impact block 1401. Affected by this impact force, the vibration box 14 is forced to shift to one side, and then the return spring 103 connecting the vibration box 14 and the frame 1 is compressed. As the drum 10 continues to rotate, the oscillating rod 11 leaves the first impact block 1401. At this time, the compressed return spring 103 rebounds quickly, driving the vibration box 14 to move in the opposite direction. Under the continuous rotation of the drum 10, the oscillating rod 11 will hit the second impact block 1402 again, which makes the vibration box 14 move towards the other side under force, and the return spring 103 on the other side is immediately compressed. Just like this in a cycle, the oscillating rod 11 continuously hits the impact block. Combining the alternating expansion and contraction of the return spring 103, the vibration box 14 generates continuous and regular vibrations. At the same time, the oscillating rod 10 can also contact the raw materials in the vibration box 14 to assist in mixing and stirring the raw materials.

[0045] The vibration of the vibration box 14 already makes the raw materials in a dynamic mixing state, and the oscillating rod 10 can also contact the raw materials in the vibration box 14 to assist in mixing and stirring the raw materials, making the contact and mixing between the components of the mortar more sufficient and uniform, and comprehensively improving the quality and efficiency of stirring.

[0046] Embodiment Two:

[0047] Different from Embodiment One, referring to Figure 1 - Figure 7 This embodiment also has the following further content:

[0048] Four support columns 12 are fixedly connected to the upper end of the frame body 1. The upper ends of the four support columns 12 are fixedly connected together with a feed inlet 13. The frame body 1 is rotatably connected with two transmission shafts 17. The transmission shafts 17 penetrate through the frame body 1. The transmission shafts 17 are fixedly connected with reciprocating lead screws 18. The two ends of the reciprocating lead screws 18 are respectively rotatably connected to both sides of the inner wall of the frame body 1. Two limiting rods 19 are fixedly connected to both sides of the inner wall of the frame body 1. The two reciprocating lead screws 18 are symmetrically arranged, and the two limiting rods 19 are symmetrically arranged. One end of the rotating shaft 9 away from the gearbox 8 is fixedly connected with a first synchronous pulley 901. The first synchronous pulley 901 is connected to a second synchronous pulley 903 through a first synchronous belt 902. One end of the rotating shaft 9 away from the gearbox 8 is fixedly connected with a third synchronous pulley 904. The third synchronous pulley 904 is connected to a fourth synchronous pulley 905 through a second synchronous belt. One of the transmission shafts 17 is fixedly connected with the second synchronous pulley 903, and the other transmission shaft 17 is fixedly connected with the fourth synchronous pulley 905.

[0049] A lead screw sleeve 20 is threadedly connected to the outer wall of the reciprocating lead screw 18. The limiting rod 19 penetrates through and is slidably connected to the lead screw sleeve 20;

[0050] The auxiliary feeding assembly is composed of two transmission rods 21 and two scrapers 22. The two transmission rods 21 are respectively fixedly connected to the two lead screw sleeves 20. One end of the transmission rod 21 away from the lead screw sleeve 20 is fixedly connected to the scraper 22. The scraping surface of the scraper 22 is attached to the inclined surface of the feed inlet 13. It should be noted that the threaded length of the reciprocating lead screw 18 is equal to the inner wall length of the feed inlet 13, so as to ensure that the reciprocating lead screw 18 drives the lead screw sleeve 20 to drive the scraper 22 to clean without hitting the feed inlet 13.

[0051] In this embodiment, the raw material enters the equipment through the feed inlet 13. At the same time, the rotating shaft 9 rotates driven by the gearbox 8. The first synchronous pulley 901 at one end of the rotating shaft 9 drives the second synchronous pulley 903 to rotate through the first synchronous belt 902, and the third synchronous pulley 904 at the other end drives the fourth synchronous pulley 905 to rotate through the second synchronous belt. Since the second synchronous pulley 903 and the fourth synchronous pulley 905 are respectively fixed on the two transmission shafts 17, the two transmission shafts 17 start to rotate.

[0052] The rotation of the transmission shaft 17 drives the reciprocating lead screw 18 to rotate. The lead screw sleeve 20 on the outer wall of the reciprocating lead screw 18 makes a reciprocating linear motion along the reciprocating lead screw 18 under the action of the thread. At the same time, the lead screw sleeve 20 is restricted by the limiting rod 19 to ensure the stability of the motion. The transmission rod 21 fixedly connected to the lead screw sleeve 20 moves along with the movement of the lead screw sleeve 20, and then drives the scraper 22 to reciprocally scrape along the inclined surface of the feed inlet 13, preventing the raw material from accumulating at the feed inlet 13 and assisting the raw material to smoothly enter the vibration box 14.

[0053] Embodiment Three:

[0054] Refer to Figure 1- Figure 8 , compared with the first embodiment and the second embodiment, in this embodiment:

[0055] The blanking assembly is composed of a blanking port 15, two hydraulic cylinders 16, a connecting block 1602, a first rotating shaft 1603 and a fixing block 1604. The blanking port 15 is fixedly connected to the lower end of the vibration box 14. The two hydraulic cylinders 16 are fixedly connected to the outer wall of the blanking port 15. The two hydraulic cylinders 16 are symmetrically arranged. A piston rod 1601 is slidably connected to the inner wall of the hydraulic cylinder 16. The piston rod 1601 penetrates and is slidably connected to the blanking port 15. The piston rod 1601 is fixedly connected to the connecting block 1602. The first rotating shaft 1603 penetrates and is rotatably connected to the connecting block 1602. The first rotating shaft 1603 is fixedly connected to the fixing block 1604. Two second rotating shafts 1403 are rotatably connected to both ends of the inner wall of the vibration box 14. The two second rotating shafts 1403 are symmetrically arranged. A blanking plate 1404 is rotatably connected to the outer wall of the second rotating shaft 1403. The lower end of the blanking plate 1404 is fixedly connected to the fixing block 1604. It should be noted that sealing gaskets are provided on both blanking plates 1404 to prevent the slurry from leaking out of the blanking plates 1404.

[0056] In this embodiment, when the mortar mixing is completed, the two hydraulic cylinders 16 are started. At the same time, the oscillating rod 11 continuously maintains a rotating state. The piston rod 1601 in the hydraulic cylinder 16 extends, driving the connecting block 1602 to move. The connecting block 1602 drives the fixing block 1604 to move through the first rotating shaft 1603. The fixing block 1604 is fixedly connected to the lower end of the blanking plate 1404. The blanking plate 1404 is rotatably connected to the second rotating shaft 1403. Therefore, the blanking plate 1404 rotates around the second rotating shaft 1403 under the drive of the fixing block 1604, thereby opening the blanking port 15. The mixed slurry is smoothly discharged from the equipment through the blanking port 15 with the assistance of the shaking of the vibration box 14, effectively preventing blockage during blanking.

[0057] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
