[0033] Example 1
[0034] A liftable vertical mixer includes a mixer body 1, at least three lifting mechanisms 2, and at least three anti-fall mechanisms 3. The lifting mechanisms 2 are evenly and vertically arranged around the mixer body 1, and the top of the lifting mechanism 2 is connected to the mixer body 1, while the bottom of the lifting mechanism 2 is connected to the ground.
[0035] In this embodiment, a lifting mechanism 2 is set up to support the mixer body 1. When feeding materials, the height of the mixer body 1 is lowered so that the mortar truck transported from the concrete plant can be directly fed into the mixer body 1. When unloading materials, the height of the mixer body 1 is raised so that the materials can be easily received from the discharge port. No additional equipment or civil engineering is required, which improves the efficiency and safety of feeding and unloading.
[0036] In this embodiment, the mixer body 1 includes a cylinder 11, a mounting base 12, stirring blades 13, and a driving device. The cylinder 11 is disposed above the mounting base 12, with an opening at the top of the cylinder 11 forming a feeding port and a discharge port located at the bottom of one side of the cylinder 11. The stirring blades 13 are disposed inside the cylinder 11, and the driving device is disposed on the mounting base 12, and the driving device is used to drive the stirring blades 13 to rotate.
[0037] The lifting mechanism 2 is a hydraulic cylinder, including a cylinder body 21 and a piston rod 22. The top of the cylinder body 21 is connected to the top of the side wall of the cylinder body 11 via an upper support 23, and the bottom of the cylinder body 21 is connected to the mounting base 12 via a fixed flange 24. The piston rod 22 extends from the bottom of the cylinder body 21, and a lower base 25 for connecting to the ground is provided at the bottom of the piston rod 22.
[0038] The vertical mixer in this embodiment also includes a balance valve 4, a flow divider 5, a distribution valve 6, an oil pump 7, and an oil tank 8.
[0039] The distribution valve 6 includes a first end, a second end, a third end, and a fourth end. The distribution valve 6 is used to control the first end to be connected to the third end and the second end to be connected to the fourth end, or the first end to be connected to the fourth end and the second end to be connected to the third end.
[0040] The first and second ends are connected in series between the oil pump 7 and the oil tank. The third end is connected to the rod end of each oil cylinder via the balance valve 4, and the fourth end is connected to the head end of each oil cylinder via the distributor 5. Therefore, the operator can control the mixer body 1 to slowly rise and fall via the oil pump 7 and the distribution valve 6.
[0041] Fall protection mechanisms 3 are evenly distributed around the mixer body 1. Each fall protection mechanism 3 includes an inner support leg 31, an outer support leg 32, and a limiting component. The inner support leg 31 is vertically positioned, with its bottom connected to the ground. The outer support leg 32 is connected to the mixer body 1 and is slidably mounted on the inner support leg 31. The limiting component restricts the height of the outer support leg 32 on the inner support leg 31 to prevent it from falling downwards along the inner support leg 31.
[0042] In this embodiment, by setting an anti-fall mechanism 3, the mixer can be limited after it is raised, ensuring that the mixer does not tip over or lower after the oil cylinder is depressurized.
[0043] In this embodiment, the inner support leg 31 is provided with a plurality of limiting through holes 311 from top to bottom. The limiting component includes a limiting pin 33, which is detachably inserted into any one of the limiting through holes 311.
[0044] When the mixer body 1 rises to the predetermined height, the limiting pin 33 is inserted into the appropriate limiting through hole 311, which is generally the first limiting through hole 311 from top to bottom below the bottom of the outer support leg 32. After that, after the oil cylinder is depressurized, the limiting pin 33 abuts against the bottom of the outer support leg 32, thereby preventing the mixer body 1 from falling.
[0045] Example 2
[0046] The difference between this embodiment and Embodiment 1 is that one side of the inner support leg 31 is hollowed out and several limiting cross braces 312 are arranged sequentially from top to bottom. The limiting components include anti-fall blocks 322 and trigger blocks 323.
[0047] The anti-fall block 322 is disposed inside the outer support leg 32 on the side near the limiting cross brace 312, and the anti-fall block 322 is rotatably connected to the inner wall of the outer support leg 32 via a rotating shaft 321. The side of the anti-fall block 322 near the limiting cross brace 312 is inclined downward, and the bottom front end of the anti-fall block 322 is connected to the inner wall of the outer support leg 32 via a first elastic member 325.
[0048] The trigger block 323 is rotatably mounted on the top of the anti-fall block 322 near the inner support leg 31, and a buffer groove 324 is provided between the trigger block 323 and the side of the anti-fall block 322 near the limiting cross brace 312. The other side of the trigger block 323 abuts against the anti-fall block 322, and the top of the trigger block 323 is connected to the top of the anti-fall block 322 through the second elastic member 326.
[0049] Additionally, a limit rod 327 is provided inside the outer outrigger 32. The limit rod 327 engages with the bottom of the anti-fall block 322 near the limit cross brace 312, thereby limiting the downward tilt angle of the anti-fall block 322 near the limit cross brace 312. A limit block 328 is provided inside the outer outrigger 32. The limit block 328 engages with the bottom of the anti-fall block 322 away from the limit cross brace 312, thereby limiting the rotation angle of the anti-fall block 322 when the outer outrigger 32 falls.
[0050] like Figure 6 As shown, when the mixer body 1 rises, the limit cross brace 312 presses the trigger block 323 against the buffer groove 324 in sequence, so that the limit mechanism can pass smoothly through each limit cross brace 312.
[0051] like Figure 7As shown, when the mixer body 1 descends, the limiting cross brace 312 pushes the trigger block 323 upward and pushes the anti-fall block 322 to a horizontal position. At this time, if the mixer body 1 descends slowly, the anti-fall block 322 returns to the inclined state under the pull of the first elastic element 325, thus smoothly passing through each limiting cross brace 312. However, when the mixer body 1 falls rapidly, the anti-fall block 322 does not have time to return to the inclined state, and the limiting cross brace 312 supports the anti-fall block 322, thereby preventing the limiting mechanism and the mixer body 1 from continuing to fall downward.
[0052] In this embodiment, the anti-fall block 322 and the trigger block 323 work together to ensure that the mixer body 1 moves smoothly when rising and slowly descending, and to quickly and automatically limit the mixer body 1 when the mixer falls rapidly, so as to avoid accidents.
[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
