Description

Technical Field

[0001] The present application relates to the field of concrete processing, and in particular to a machine-made sand concrete proportioning device. Background Art

[0002] Concrete is a general term for engineering composite materials that are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates, mixed with water (which may contain admixtures and additives) in a certain proportion and stirred to obtain cement concrete. The sand used in concrete is mostly machine-made sand, which refers to sand made through other processing, and the finished product is more regular.

[0003] Please refer to the utility model with announcement number CN217226090U, which is a machine-made sand concrete proportioning device, including a mixing bin, above which are arranged parallel No. 1 feed bin, No. 2 feed bin and No. 3 feed bin, the bottoms of No. 1 feed bin, No. 2 feed bin and No. 3 feed bin are fixedly connected to the top of the mixing bin, and No. 1 feed bin, No. 2 feed bin and No. 3 feed bin are respectively provided with feed ports on the tops and discharge ports on the bottoms, the discharge ports and the mixing bin are through-connected, and also include No. 1 mixing shaft, one end of the No. 1 mixing shaft is horizontally arranged and rotatably connected to the inner wall of the No. 3 feed bin, and the other end passes through the No. 3 feed bin, No. 2 feed bin and No. 1 feed bin and is connected to a motor. The structure involved in the utility model has the advantages of being able to mix in batches and quickly discharge the mixed raw materials.

[0004] Combining the technical features of the above patent with the prior art, the inventors found that the above patent helps to improve the uniformity and efficiency of concrete mixing by mixing multiple concrete mixtures in a single compartment. However, in actual use, there are differences in the mixing speeds required for compartmentalizing concrete materials. For example, the mixing speeds required for gel materials with strong viscosity are different from those for sand and gravel. Under the traction of a single stirring shaft, the mixing load of the stirring shaft is unevenly distributed in multiple compartments, which can easily reduce the service life of the stirring shaft. In this regard, a machine-made sand concrete mixing device is proposed. Utility Model Content

[0008] By adopting the above technical solution, the stirring rods between different compartments can achieve variable speed stirring through gear transmission with different diameters, thereby improving the stirring adaptability of different compartments for different concrete ingredients.

[0009] Furthermore, a stirring motor is fixedly installed on the outside of one of the sub-bins, and the output end of the stirring motor is fixedly connected to a stirring rod in one of the sub-bins.

[0017] Furthermore, a limit block is fixedly mounted on the end of the first extension rod, and a diameter of the limit block is greater than a diameter of the sliding sleeve.

[0018] By adopting the above technical solution, the sliding limit position of the sliding sleeve relative to the first extension rod can be limited.

[0019] Furthermore, a positioning pin is fixedly installed on the outside of the first extension rod, a positioning groove is opened on the inner wall of the sliding sleeve, and the positioning pin is slidably connected to the positioning groove.

[0030] See also Figure 1 In this embodiment, a machine-made sand concrete proportioning device includes a proportioning bin 1. The top of the proportioning bin 1 is connected to three sub-bins 2. The three sub-bins 2 are connected to the proportioning bin 1 through material pipes of different lengths, so that the height positions of the stirring rods inside the three sub-bins 2 are staggered with each other. A shut-off valve is installed on the material pipe connecting the sub-bins 2 for easy control by the user.

[0031] In this embodiment, a stirring motor 3 is fixedly installed on the outside of a sub-compartment 2, and the output end of the stirring motor 3 is fixedly connected to a stirring rod in a sub-compartment 2. At the same time, the output end of the stirring motor 3 pulls the stirring rod inside the proportioning bin 1 through a transmission wheel for stirring.

[0032] In order to achieve variable speed traction of the stirring rods inside different sub-compartments 2, a transmission structure is provided on the outside of the sub-compartment 2, and the transmission structure includes a first extension rod 4 rotatably installed on the outer wall of the sub-compartment 2, the first extension rod 4 is fixedly connected to the stirring rod inside the sub-compartment 2, the first extension rod 4 is located on the right side of the sub-compartment 2 and is used to transmit the rotation of the stirring rod, and a second extension rod 8 is rotatably installed on the left side of the sub-compartment 2, and the second extension rod 8 is used to cooperate with the first extension rod 4 to adjust the rotation speed.

[0033] Furthermore, a sliding sleeve 5 is slidably installed on the outside of the first extension rod 4, a first gear set 6 is fixedly installed on the outside of the sliding sleeve 5, and a second gear set 9 is fixedly installed on the outside of the second extension rod 8. The first gear set 6 and the second gear set 9 are meshed with each other, so that the second extension rod 8 is pulled by the rotation of the first extension rod 4.

[0034] It should be noted that the first gear set 6 and the second gear set 9 each include three gears with proportionally enlarged diameters. The three gears on the first gear set 6 are, from left to right, a small gear, a large gear, and a medium gear. The three gears on the second gear set 9 are, from left to right, a large gear, a small gear, and a medium gear. The small gear teeth are meshed with the large gear, and the medium gear teeth are meshed with the medium gear.

[0035] Furthermore, the spacing between the three gears in the first gear set 6 is smaller than the spacing between the three gears on the second gear set 9 , so that only a single gear on the first gear set 6 can be meshed with the second gear set 9 .

[0036] In order to enhance the rotational stability of the first extension rod 4 and the second extension rod 8 , a stabilizing rod 10 is rotationally connected between the first extension rod 4 and the adjacent sub-compartment 2 , and a stabilizing rod 10 is also rotationally connected between the second extension rod 8 and the adjacent sub-compartment 2 .

[0037] See also Figure 2In order to adjust the position of the first gear set 6 relative to the second gear set 9, a vertical plate 11 is fixedly installed on the top of the proportioning bin 1, an adjusting wheel 12 is rotatably installed on the front of the vertical plate 11, and a hand wheel 13 is rotatably installed on the rear side of the vertical plate 11. The hand wheel 13 is fixedly connected to the adjusting wheel 12, and the hand wheel 13 can be used to facilitate the rotation of the adjusting wheel 12.

[0038] An extension column 14 is fixedly installed on the circumferential periphery of the adjusting wheel 12, and the extension column 14 can move in a circular trajectory with the adjusting wheel 12. A U-shaped connecting frame 15 is rotatably installed on the front of the extension column 14. The connecting frame 15 is located outside a gear in the first gear set 6. The connecting frame 15 moves in a circular trajectory, and can pull the first gear set 6 and the sliding sleeve 5 to slide horizontally on the first extension rod 4. To ensure that the connecting frame 15 does not detach from the outside of the first gear set 6, the diameter of the adjusting wheel 12 is smaller than the radius of the largest gear in the first gear set 6, so that the connecting frame 15 can not cross the outer end of the arc of the gear in the first gear set 6 under the circular trajectory movement, thereby preventing the connecting frame 15 from detaching from the outer edge of the first gear set 6.

[0039] See also Figure 3-4 A limit block 7 is fixedly installed at the end of the first extension rod 4. The diameter of the limit block 7 is larger than the diameter of the sliding sleeve 5. The limit block 7 can limit the sliding limit position of the sliding sleeve 5 relative to the first extension rod 4.

[0040] A positioning pin 17 is fixedly installed on the outside of the first extension rod 4, and a positioning groove 16 is opened on the inner wall of the sliding sleeve 5. The positioning pin 17 is slidably connected to the positioning groove 16. The positioning pin 17 slides relative to the positioning groove 16, so that the rotation of the sliding sleeve 5 relative to the first extension rod 4 is restricted.

[0041] It should be noted that three latches 18 are plugged into the handwheel 13, and the latches 18 are plugged into the vertical plate 11. Three plug-in positions corresponding to the latches 18 are provided on the vertical plate 11, which correspond to the three different meshing positions of the first gear set 6 and the second gear set 9 respectively. By plugging the latches 18 and the vertical plate 11, the rotation of the handwheel 13 can be restricted.

[0042] The working principle of the above embodiment is:

[0043] The user puts the machine-made sand for concrete mixing into the three sub-compartments 2 respectively, and rotates the hand wheel 13, which drives the adjusting wheel 12 on the vertical plate 11 to rotate. The extension column 14 on the adjusting wheel 12 drives the connecting frame 15 to move in a circular trajectory. The connecting frame 15 is connected to the outside of the large gear in the first gear set 6 by sliding, thereby pulling the first gear set 6 together with the sliding sleeve 5 to slide outside the first extension rod 4, so that the meshing gears on the first gear set 6 and the second gear set 9 are replaced, and the transmission ratio is adjusted, thereby realizing the variable speed rotation traction of the stirring rods inside the two adjacent sub-compartments 2. After the adjustment is completed, the pin 18 is inserted into the position of the vertical plate 11 to fix the hand wheel 13.
