Description

Technical Field

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

[0002] Concrete is a widely used building material consisting of a mixture of a binder (cement), coarse and fine aggregates (such as sand and gravel), water, and possible chemical additives. Concrete is favored for its high strength, durability, plasticity, and cost-effectiveness, and is used to construct various structures such as buildings, bridges, roads, dams, and tunnels.

[0003] Concrete mixing is a crucial step in construction. It involves mixing cement, sand, gravel (aggregate), water and possible additives into a homogeneous, highly plastic material. However, during the mixing process, dust from the cement and various impurities will be stirred up, fly up and spread out, and eventually cause dust pollution to the surrounding environment.

[0004] In order to solve the above technical problems, we will design a concrete mixing device with the function of suppressing and controlling dust. Utility Model Content

[0005] In order to overcome the disadvantage of dust generation during the mixing process, the utility model provides a concrete mixing device with a dust reduction function.

[0006] The technical solution of the utility model is as follows: a concrete mixing device includes a frame, a cylinder is fixedly connected to the upper end of the frame, a large motor is fixedly connected to the side of the cylinder away from the frame, a large gear is rotatably connected to the side of the cylinder away from the frame, the large gear is fixedly connected to the output end of the large motor, three stirring rods are rotatably evenly connected to the side of the inner wall of the cylinder away from the frame, the stirring rods and the large gear are meshed with each other, a suction head is fixedly connected to the side of the cylinder away from the frame, a connecting round tube is fixedly connected to the side of the suction head close to the frame, the connecting round tube is communicated with the suction head, and the frame is close to the frame. A fan is fixedly connected to the side near the cylinder, and the air inlet of the fan is connected to the connecting circular tube. A connecting frame is fixedly connected to the front side of the lower end of the cylinder, and the air outlet of the fan is connected to the connecting frame. A connecting frame is fixedly connected to the side of the cylinder close to the frame, and the connecting frame is connected to the cylinder. A push plate is slidably connected to the connecting frame. A symmetrical large cylinder is fixedly connected to the side of the connecting frame close to the frame, and the telescopic rod of the large cylinder is fixedly connected to the push plate. A baffle is slidably connected to the side of the cylinder close to the frame, and a small cylinder is fixedly connected to the side of the connecting frame close to the frame, and the telescopic rod of the small cylinder is fixedly connected to the baffle.

[0007] In one embodiment, in order to ensure the stirring effect, we redesigned the stirring rod so that the stirring rod is close to the inner wall of the cylinder during rotation.

[0008] In one embodiment, a plurality of holes are opened at the rear end of the connection frame to ensure that cement dust in the dust is isolated and retained in the connection frame.

[0009] In one embodiment, a tire is rotatably connected to the frame, which can ensure the rapid transfer of the entire stirring device so that the user can use the stirring device more conveniently.

[0010] In one embodiment, the inner wall of the cylinder is coated with a non-stick coating made of epoxy resin to ensure that the concrete does not adhere when the concrete is mixed.

[0011] In one embodiment, a connecting frame is further included. The connecting frame is symmetrically fixed to the side of the cylinder away from the frame. An angled plate is rotatably connected to the connecting frame. The angled plate contacts the front end of the cylinder. Symmetrical small motors are fixed to the upper left and right sides of the front end of the cylinder. The output ends of the small motors are fixed to the left and right sides of the upper end of the angled plate.

[0012] In one embodiment, it also includes a rounded corner box, which is fixed to the side of the frame close to the cylinder, and a water pump is fixed to the side of the rounded corner box close to the cylinder, and the water pump is connected to the rounded corner box, and a connecting pipe is fixed to the side of the water pump close to the cylinder, and the connecting pipe is connected to the water pump, and the connecting pipe is fixed to the side of the cylinder away from the frame, and a symmetrical lower nozzle is fixed to the side of the connecting pipe close to the frame, and the lower nozzle is fixed to the side of the cylinder close to the frame, and the lower nozzle is connected to the connecting pipe, and the upper end of the lower nozzle is fixed to the upper nozzle, and the lower nozzle is connected to the upper nozzle, and the symmetrical upper nozzle is fixed to the side of the cylinder away from the frame.

[0013] In one embodiment, the directions of the spray holes of the lower nozzle and the upper nozzle are different to ensure the dust suppression effect, ensure that no dust is generated around the stirring device, and prevent users from inhaling dust.

[0014] Beneficial effects: After starting the mixing work, in order to ensure the mixing effect, we first use the intermeshing mixing rod and the large gear to achieve planetary rotation to ensure more thorough and comprehensive mixing. At this time, more dust will be generated, which will affect the surrounding environment and the health of the users. In order to ensure the dust suppression effect, the dust is first sucked in through the fan and the suction head, and then the cement dust in the dust is filtered out through the connecting frame, and then the cement dust is pushed back into the cylinder through the push plate to avoid waste of cement dust and achieve accurate concrete ratio. In order to ensure that the concrete flows into the connecting frame when the cylinder is working, we block the concrete through the baffle, and achieve better filtering effect through the cooperation of the baffle and the push plate.

[0015] Conventional stirring rods will have a missing effect during the stirring process, so we use specially designed stirring rods to achieve better stirring effects.

[0016] In order to better filter out the cement dust in the dust, we have opened multiple holes at the rear end of the connecting frame, so that the cement dust in the dust can remain completely in the connecting frame to ensure the reuse of the cement dust.

[0017] In order to use the mixing device better and more conveniently, we have set tires under the frame to ensure that users can quickly transfer the mixing device.

[0018] In order to ensure that the concrete in the cylinder will not produce residue when discharged, we coat the inner wall of the cylinder with a non-stick coating made of epoxy resin to ensure the non-stick properties of the inner wall of the cylinder.

[0019] In order to better prevent dust from flying out, we use a rotatable bevel plate to block the front end of the cylinder to ensure that the dust only remains in the cylinder and is thoroughly processed by the suction head. In order to ensure that it does not hinder the discharge of the cylinder, we place the rotation center of the bevel plate on the left and right sides of the cylinder.

[0020] In order to achieve better dust reduction effect, we set up nozzles on the left and right sides of the cylinder to achieve better external dust reduction effect. After the liquid in the rounded corner box is used up, we can also replenish the liquid through the water inlet set on the outside of the rounded corner box, and through the connection between the lower nozzle and the upper nozzle, we can achieve more comprehensive dust reduction.

[0021] In order to ensure the dust reduction effect, we set the nozzle angles of the lower nozzle and the upper nozzle to achieve a more comprehensive liquid spraying effect, and through the spraying of liquid, achieve the dust suppression effect of the stirring device.

DETAILED DESCRIPTION

[0031] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0032] Example 1: A concrete mixing device, such as Figures 1-6 As shown, it includes a frame 1, a cylinder 2 is fixedly connected to the upper end of the frame 1, a large motor 3 is fixedly connected to the rear end of the cylinder 2, a large gear 4 is rotatably connected to the rear end of the inner wall of the cylinder 2, the large gear 4 is fixedly connected to the output end of the large motor 3, three stirring rods 5 are rotatably and evenly connected to the rear end of the inner wall of the cylinder 2, the rear end of the stirring rods 5 are meshed with the large gear 4, a suction head 10 is fixedly connected to the front end of the cylinder 2, a connecting round tube 8 is fixedly connected to the lower end of the suction head 10, and the connecting round tube 8 is connected to the suction head 10. A fan 9 is fixedly connected to the front side of the upper end of the frame 1 The air inlet of the fan 9 is connected to the rear end of the connecting circular tube 8, the front side of the lower end of the cylinder 2 is fixedly connected to a connecting frame 6, the air outlet of the fan 9 is connected to the connecting frame 6, the connecting frame 6 is connected to the cylinder 2, and a push plate 11 is slidably connected to the connecting frame 6. The lower end of the connecting frame 6 is fixedly connected to a symmetrical large cylinder 7, and the telescopic rod of the large cylinder 7 is fixedly connected to the push plate 11. The front side of the lower end of the cylinder 2 is slidably connected to a baffle 12, and a small cylinder 13 is fixedly connected to the upper right side of the connecting frame 6, and the telescopic rod of the small cylinder 13 is fixedly connected to the right end of the baffle 12.

[0033] After starting work, first start the large motor 3, and then the large motor 3 drives the large gear 4 to rotate clockwise. Because the rear end of the stirring rod 5 is meshed with the large gear 4, the stirring rod 5 is driven by the large gear 4 to rotate counterclockwise. After the large motor 3 is started, the fan 9 is also started at the same time. The fan 9 sucks the flying dust through the suction head 10 and sucks it into the connecting frame 6 through the connecting round pipe 8. After the fan 9 has worked for a period of time, the fan 9 stops running, the small cylinder 13 starts, and after the small cylinder 13 starts to retract, it drives the block Plate 12 moves to the right, and after moving a distance, the small cylinder 13 stops running, and then the large cylinder 7 starts and extends, and pushes the push plate 11 upward. When the push plate 11 is aligned with the inner wall of the cylinder 2, the large cylinder 7 retracts again. After the push plate 11 returns to its original position, the small cylinder 13 starts again, extends again, and moves the baffle 12 to the left. When the baffle 12 blocks the upper end of the connecting frame 6, the fan 9 starts working again. When the mixing work is completed, the large motor 3 stops running, and then the fan 9 also stops running.

[0034] Example 2: Based on Example 1, Figure 2 As shown, in order to ensure the stirring effect, we redesigned the stirring rod 5 so that the stirring rod 5 is close to the inner wall of the cylinder 2 during rotation.

[0035] In order to ensure the stirring effect of the cylinder 2, we redesigned the appearance of the stirring rod 5, and the rotation range of the stirring rod 5 will be very close to the inner wall of the cylinder 2.

[0036] like Figure 6 As shown, a plurality of holes are opened at the rear end of the connection frame 6 to ensure that cement dust in the dust is isolated and retained in the connection frame 6.

[0037] In order to ensure the dust filtering effect of the connecting frame 6, a plurality of holes are opened at the rear end of the connecting frame 6 to keep the cement dust in the dust inside the connecting frame 6 to avoid wasting the cement dust.

[0038] like Figure 1 As shown, a tire is rotatably connected to the frame 1, which can ensure the rapid transfer of the entire stirring device so that the user can use the stirring device more conveniently.

[0039] In order to ensure faster transfer of the stirring device, a tire is rotatably connected to the frame 1 to ensure that the user can use the stirring device more conveniently.

[0040] like Figure 5 As shown, the inner wall of the cylinder 2 is coated with a non-stick coating made of epoxy resin to ensure that the concrete will not adhere when mixing.

[0041] In order to ensure that the concrete does not adhere to the inner wall of the cylinder 2 during the mixing process, we apply a non-stick coating made of epoxy resin on the inner wall of the cylinder 2 to ensure that no residue will remain when the concrete is discharged.

[0042] like Figure 7 As shown, it also includes a connecting frame 15, which is symmetrically fixed to the left and right sides of the front end of the cylinder 2. The connecting frame 15 is rotatably connected to the bevel plate 14, which is in contact with the front end of the cylinder 2. Small motors 16 are fixed to the upper parts of the left and right sides of the front end of the cylinder 2, and the output end of the small motor 16 is fixed to the upper end of the adjacent bevel plate 14.

[0043] After the large motor 3 starts working, the small motor 16 starts to run and starts to rotate clockwise. At this time, the small motor 16 brings the bevel plate 14 to rotate toward the front end of the cylinder 2. The bevel plate 14 eventually contacts the front end of the cylinder 2, and then the small motor 16 stops running. After completing the stirring work, the small motor 16 rotates counterclockwise and brings the bevel plate 14 to rotate outward.

[0044] like Figure 8 As shown, it also includes a rounded corner box 17, which is fixedly connected to the rear side of the upper end of the frame 1, and a water pump 18 is fixedly connected to the upper end of the rounded corner box 17, which is connected to the rounded corner box 17, and a connecting pipe 19 is fixedly connected to the upper end of the water pump 18, which is connected to the water pump 18, and the connecting pipe 19 is fixed to the upper part of the cylinder 2, and a symmetrical lower nozzle 20 is fixedly connected to the lower end of the connecting pipe 19, and the lower nozzle 20 is fixedly connected to the left and right sides of the middle part of the cylinder 2, the lower nozzle 20 is connected to the connecting pipe 19, and an upper nozzle 21 is fixedly connected to the upper end of the lower nozzle 20, the lower nozzle 20 is connected to the upper nozzle 21, and the symmetrical upper nozzle 21 is fixedly connected to the left and right sides of the upper part of the cylinder 2.

[0045] When the small motor 16 starts working, the water pump 18 also starts working. The water pump 18 extracts the liquid from the rounded corner box 17, and the water pump 18 discharges the liquid from the connecting pipe 19 to the lower nozzle 20. When the liquid fills the lower nozzle 20, the liquid is transferred from the lower nozzle 20 to the upper nozzle 21. When the stirring work is completed, the water pump 18 stops running.

[0046] like Figure 8 As shown, the directions of the spray holes of the lower nozzle 20 and the upper nozzle 21 are different to ensure the dust suppression effect, ensure that no dust is generated around the stirring device, and prevent users from inhaling dust.

[0047] In order to ensure the dust reduction effect, the spray holes of the lower nozzle 20 and the upper nozzle 21 are oriented in different directions to ensure a better dust reduction effect after the liquid is sprayed out.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
