Description

Technical Field

[0001] The utility model belongs to the technical field of concrete mixing, and particularly relates to a mixing device convenient for adding a concrete waterproofing agent. Background Art

[0002] In small construction sites or construction sites where large machinery cannot enter, a handheld concrete mixer is used. During mixing, the concrete raw materials are piled on the ground. When adding water after the dry materials are mixed, workers can dig a pit in the middle of the dry materials to hold water. However, due to the poor water absorption of the concrete after mixing the water body and the fact that the concrete will flow by itself and tend to flatten, when adding the waterproofing agent, if the waterproofing agent is directly poured, it will flow on the surface of the concrete. During the mixing process, the waterproofing agent may even flow outside the coverage area of the concrete, resulting in waste of the waterproofing agent and poor mixing effect, and it is inconvenient to add and mix the waterproofing agent. Content of the Utility Model

[0003] The utility model provides a mixing device convenient for adding a concrete waterproofing agent, which has the characteristics of being able to gradually add the waterproofing agent during the mixing process and not causing pipeline blockage.

[0004] The utility model provides the following technical solution: A mixing device convenient for adding a concrete waterproofing agent, including a handheld concrete mixer and a concrete baffle. A waterproofing agent delivery pipe is installed on the handheld concrete mixer. One end of the waterproofing agent delivery pipe is fixedly connected with a thin-diameter nozzle, and the thin-diameter nozzle is installed on the top wall of the concrete baffle. A shielding curved plate is arranged below the thin-diameter nozzle. The outer wall of the shielding curved plate is fixedly connected with an outer-ring diversion curved plate, and the outer edge of the outer-ring diversion curved plate bends downward. The outer wall of the outer-ring diversion curved plate is detachably connected with a fitting positioning groove block, and the fitting positioning groove block is fixedly connected to the inner wall of the concrete baffle.

[0005] Wherein, a pumping pump body is installed on the waterproofing agent delivery pipe, and one end of the waterproofing agent delivery pipe is fixedly connected with a rigid graduated pipe.

[0006] Wherein, an adjusting sleeve is sleeved on the outer wall of the rigid graduated pipe, and a flipping extrusion rod is hinged to one side of the adjusting sleeve.

[0007] Wherein, the shielding curved plate is recessed downward, a protective sponge block is fixedly connected to the inner wall of the shielding curved plate, and a connecting bolt is installed on the outer-ring diversion curved plate, and the connecting bolt passes through the concrete baffle.

[0008] Wherein, a waterproofing agent storage barrel is arranged outside the rigid graduated pipe, and the adjusting sleeve and the flipping extrusion rod clamp the side wall of the waterproofing agent storage barrel.

[0009] The beneficial effects of the present utility model are as follows: By means of a fine-diameter nozzle with a smaller diameter, the discharge flow rate of the waterproofing agent can be accelerated, and it is more difficult for fine particles to enter the fine-diameter nozzle. The cooperation of the shielding curved plate, the outer ring diversion curved plate, and the fitting positioning groove block can block the splashing concrete, and the curved gap between the outer ring diversion curved plate and the fitting positioning groove block serves as the discharge path for the waterproofing agent, increasing the difficulty for fine particles in the concrete to approach the opening of the fine-diameter nozzle, so that the waterproofing agent delivery pipe and the fine-diameter nozzle will not be blocked by the concrete. Moreover, the arc cooperation of the outer ring diversion curved plate and the fitting positioning groove block can divert the waterproofing agent and reduce the flow rate of the waterproofing agent, thereby avoiding the splashing of the waterproofing agent.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Please refer to Figures 1 - 4 , the present utility model provides the following technical solutions: A mixing device for facilitating the addition of concrete waterproofing agent, including a hand-held concrete mixer 1 and a concrete baffle 11. A waterproofing agent delivery pipe 2 is installed on the hand-held concrete mixer 1. One end of the waterproofing agent delivery pipe 2 is fixedly connected to a fine-diameter nozzle 21. The fine-diameter nozzle 21 is installed on the top wall of the concrete baffle 11. A shielding curved plate 3 is provided below the fine-diameter nozzle 21. The outer wall of the shielding curved plate 3 is fixedly connected to an outer ring diversion curved plate 31. The outer edge of the outer ring diversion curved plate 31 bends downward. The outer wall of the outer ring diversion curved plate 31 is detachably connected to a fitting positioning groove block 32. The fitting positioning groove block 32 is fixedly connected to the inner wall of the concrete baffle 11.

[0017] In this implementation: The staff holds the handheld concrete mixer 1 to mix the concrete. When adding the waterproofing agent, the waterproofing agent delivery pipe 2 delivers the waterproofing agent to the thin-diameter nozzle 21. After the waterproofing agent is discharged through the thin-diameter nozzle 21, it enters the shielding curved plate 3. Subsequently, the waterproofing agent flows downward through the gap between the outer ring diversion curved plate 31 and the fitting positioning groove block 32 and then drips onto the mixing wheel of the handheld concrete mixer 1. The mixing wheel of the handheld concrete mixer 1 mixes the waterproofing agent into the concrete. During the addition process, by means of the thinner-diameter thin-diameter nozzle 21, the discharge flow rate of the waterproofing agent can be accelerated, and it is more difficult for fine particles to enter the thin-diameter nozzle 21. The shielding curved plate 3, the outer ring diversion curved plate 31, and the fitting positioning groove block 32 cooperate to block the splashing concrete, and the curved gap between the outer ring diversion curved plate 31 and the fitting positioning groove block 32 serves as the discharge path for the waterproofing agent, increasing the difficulty for fine particles in the concrete to approach the opening of the thin-diameter nozzle 21, so that the waterproofing agent delivery pipe 2 and the thin-diameter nozzle 21 will not be blocked by the concrete. Moreover, the outer ring diversion curved plate 31 and the fitting positioning groove block 32 cooperate to guide the waterproofing agent and reduce the flow rate of the waterproofing agent, thereby avoiding the splashing of the waterproofing agent. After the device is used, the staff cleans each component of the device to prevent the concrete from adhering and solidifying on the surfaces of each component of the device. When the concrete solidifies at the shielding curved plate 3, the outer ring diversion curved plate 31, and the fitting positioning groove block 32 and obstructs the gap between the outer ring diversion curved plate 31 and the fitting positioning groove block 32, the staff can remove the shielding curved plate 3 and the outer ring diversion curved plate 31 from the fitting positioning groove block 32. After cleaning the solidified concrete, the shielding curved plate 3 and the outer ring diversion curved plate 31 are installed again in the inner groove of the fitting positioning groove block 32.

[0018] A pumping body 22 is installed on the waterproofing agent delivery pipe 2, and one end of the waterproofing agent delivery pipe 2 is fixedly connected to a rigid graduated pipe 23; by setting the pumping body 22, the waterproofing agent can be pumped through the rigid graduated pipe 23 and delivered to the waterproofing agent delivery pipe 2. The graduations on the rigid graduated pipe 23 serve as a reference. By adjusting the depth of insertion of the rigid graduated pipe 23 into the waterproofing agent in cooperation with the waterproofing agent storage bucket 4, quantitative extraction of the waterproofing agent can be achieved. When adjusting, observe the position where the liquid level in the waterproofing agent storage bucket 4 contacts the rigid graduated pipe 23.

[0019] An adjusting sleeve 24 is sleeved on the outer wall of the rigid graduated pipe 23, and a flipping extrusion rod 25 is hinged to one side of the adjusting sleeve 24; by setting the adjusting sleeve 24 and the flipping extrusion rod 25, the rigid graduated pipe 23 can be positioned. When adjusting the depth of insertion of the rigid graduated pipe 23 into the waterproofing agent, the staff adjusts the sliding of the adjusting sleeve 24 on the outer wall of the rigid graduated pipe 23, and then respectively clamps the adjusting sleeve 24 and the flipping extrusion rod 25 on both sides of the waterproofing agent storage bucket 4.

[0020] The shielding curved plate 3 is recessed downward. A protective sponge block 33 is fixedly connected to the inner wall of the shielding curved plate 3. Connecting bolts 34 are installed on the outer ring diversion curved plate 31, and the connecting bolts 34 pass through the concrete baffle 11; the downward recess of the shielding curved plate 3 can provide an installation space for the protective sponge block 33. The protective sponge block 33 is in contact with the concrete baffle 11, and the protective sponge block 33 plays a role in secondary insurance protection. When small-diameter particles enter the internal space of the shielding curved plate 3, the porous structure inside the shielding curved plate 3 can filter the small-diameter particles to prevent concrete particles from entering the fine-diameter nozzle 21. By setting the connecting bolts 34, the outer ring diversion curved plate 31 can be fixed, so as to install the shielding curved plate 3 and the outer ring diversion curved plate 31 in the fitting positioning groove block 32. Bolt holes matching the size of the connecting bolts 34 are opened on both the outer ring diversion curved plate 31 and the concrete baffle 11.

[0021] A waterproofing agent storage barrel 4 is provided outside the rigid scale tube 23. The adjusting sleeve 24 and the flipping extrusion rod 25 are clamped on the side wall of the waterproofing agent storage barrel 4; by setting the waterproofing agent storage barrel 4, the waterproofing agent can be accommodated. The scale on the rigid scale tube 23 is set according to the horizontal dimension of the waterproofing agent storage barrel 4 to accurately control the amount of the extracted waterproofing agent.

[0022] The working principle and usage process of the present utility model: When adding the waterproofing agent, the staff adjusts the adjusting sleeve 24 to slide on the outer wall of the rigid scale tube 23, and then respectively engages the adjusting sleeve 24 and the flipping extrusion rod 25 on both sides of the waterproofing agent storage barrel 4. The pumping pump body 22 extracts the waterproofing agent and conveys it to the waterproofing agent delivery pipe 2 and the fine-diameter nozzle 21, and drips onto the mixing wheel of the handheld concrete mixer 1 through the gap between the outer ring diversion curved plate 31 and the fitting positioning groove block 32. The mixing wheel of the handheld concrete mixer 1 mixes the waterproofing agent into the concrete. The shielding curved plate 3, the outer ring diversion curved plate 31 and the fitting positioning groove block 32 cooperate to block the splashing concrete, and the curved gap between the outer ring diversion curved plate 31 and the fitting positioning groove block 32 serves as the drainage path for the waterproofing agent, increasing the difficulty for small particles in the concrete to approach the opening of the fine-diameter nozzle 21. During the mixing process, the waterproofing agent delivery pipe 2 and the fine-diameter nozzle 21 will not be blocked by the concrete, and the outer ring diversion curved plate 31 and the fitting positioning groove block 32 cooperate to divert the waterproofing agent and reduce the flow rate of the waterproofing agent, so that splashing will not occur during the addition of the waterproofing agent.
