Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a concrete processing mixing and stirring device. Background Art

[0002] Concrete is the world's most widely used man-made civil engineering material. The concrete production process requires mixing and stirring multiple substances, which necessitates the use of a concrete mixer. A concrete mixer is a machine that mixes cement, sand and gravel aggregate, and water to create the concrete mixture.

[0003] Existing concrete mixers are usually integrated with trucks to facilitate the transportation of concrete. During transportation, the mixing drum is kept rotating to ensure that the transported concrete does not solidify.

[0004] The Chinese patent with the authorization announcement number CN202702402U discloses a concrete mixer truck discharge chute and a concrete mixer truck provided with the same, which includes a discharge chute and a concrete mixer truck using the discharge chute. When the concrete mixer truck finishes mixing the concrete, the concrete flows down the discharge chute from the discharge port, completing the unloading process. However, when the concrete mixer truck needs to pour the concrete at a certain distance from the vehicle body, it is inconvenient to unload the concrete because the length of the discharge chute cannot be adjusted. For this reason, the existing method is to add a hopper to the discharge chute. When the hopper is not in use, it can be flipped and covered on the discharge chute. When in use, it can be unfolded and connected to the discharge chute, thereby lengthening the discharge chute and facilitating unloading. However, since the hopper is not locked with the discharge chute, during the concrete transportation process, the hopper is prone to sudden unfolding due to shaking, affecting driving safety.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4As shown, the concrete processing mixing and stirring device includes a mixer body 1 and a feeding mechanism, the feeding mechanism includes a feeding funnel 2 and a discharge hopper 3, and a movable hopper 4 is hinged on the output end of the discharge hopper 3, the discharge hopper 3 and the movable hopper 4 are both made of stainless steel, with high strength and hardness, not easy to rust, and good durability, and a lifting handle 16 is provided on the movable hopper 4, so when turning the movable hopper 4, the lifting handle 16 can be held to apply force, and the lifting handle 16 can be used as a force point for turning the movable hopper 4, so that the operation is more labor-saving, and the movable hopper 4 is connected to the discharge hopper 3 through a connecting mechanism, and the connecting mechanism includes a first connecting seat 5 arranged on both sides of the discharge hopper 3 and a second connecting seat 6 arranged on both sides of the movable hopper 4, and the second connecting seat 6 is rotatably connected to the first connecting seat 5 through a rotating shaft 7, and a The locking assembly is used to limit the rotation of the rotating shaft 7 on the first connecting seat 5. When unloading, the restriction of the locking assembly can be released, and then the movable hopper 4 can be flipped over to expand and connect with the discharge hopper 3. Then, the concrete can be poured into the required position through the discharge funnel 2, the discharge hopper 3, and the movable hopper 4 in sequence, and unloading is more convenient. After unloading, the movable hopper 4 can be flipped over and covered on the discharge hopper 3. During this process, the second connecting seat 6 will be deflected relative to the first connecting seat 5 through the rotating shaft 7. The rotating shaft 7 can be locked by the locking assembly to limit the rotation of the rotating shaft 7 on the first connecting seat 5, so that the movable hopper 4 cannot continue to flip over, thereby locking the movable hopper 4 on the discharge hopper 3 to avoid the danger caused by sudden expansion of the hopper, thereby ensuring driving safety during concrete transportation and improving the use effect of the device.

[0024] See also Figure 2-5As shown, a cavity is opened inside the rotating shaft 7, and the locking assembly includes a threaded rod 8 that is slidably connected to the inside of the cavity. A locking block 9 is connected to one end of the threaded rod 8, and a threaded sleeve 10 is threadedly connected to the other end. A nesting 11 for embedding the locking block 9 is provided on the first connecting seat 5. The cross section of the locking block 9 is hexagonal. After the locking block 9 is embedded in the nesting 11, it cannot rotate, thereby ensuring the limiting effect on the rotating shaft 7. When it is necessary to lock the movable hopper 4 on the discharge hopper 3, it can be First, loosen the threaded sleeve 10, then push the threaded rod 8 to slide in the cavity until the locking block 9 is embedded in the nesting 11, and then screw the threaded sleeve 10 to make it firmly pressed against the threaded rod 8, thereby fixing the locking block 9 in the nesting 11. The nesting 11 limits the locking block 9, making the rotating shaft 7 unable to rotate, thereby locking the movable hopper 4. When unlocking is required, just loosen the threaded sleeve 10 first, move it away from the second connecting seat 6, and then push the threaded rod 8 to The locking block 9 is pushed out of the nest 11, and the limit of the locking block 9 by the nest 11 is released, so that the rotating shaft 7 can rotate normally. The operation is relatively convenient and simple. A limiting piece 14 is connected to the end of the threaded rod 8 away from the locking block 9. The limiting piece 14 can prevent the threaded sleeve 10 from being completely screwed out of the threaded rod 8 during the screwing process, and a number of anti-skid grooves 15 are evenly opened on the side wall of the threaded sleeve 10, thereby greatly increasing the friction coefficient on the side wall of the threaded sleeve 10 , making it less likely to slip when screwing the threaded sleeve 10, and the operation is easier and more labor-saving. A sliding groove 12 is provided on the side wall of the threaded rod 8 along the length direction, and a slider 13 slidably connected to the inside of the sliding groove 12 is provided on the inner wall of the cavity. When the threaded rod 8 slides inside the cavity, the slider 13 will slide along the length direction of the sliding groove 12. The sliding groove 12 can limit the sliding direction of the slider 13, so that the threaded rod 8 can only slide along the length direction of the cavity, thereby ensuring the smooth sliding of the threaded rod 8.
