[0002] Prestressed concrete duct grouting material is a key material to protect prestressed steel bars from corrosion, ensure effective transmission between them and concrete components, and quickly connect the post-tensioned prestressing force with the overall structure. The tangerine peel is generally in powder form. When used, it is generally mixed with water in a certain proportion into a slurry and then injected between concrete components.

[0003] Most of the existing grouting materials are made by mixing multiple powder materials (such as the ultra-fine high-strength plastic expansion grouting material with publication number CN106007573A); when the powder material is fed into the mixing equipment, if the feeding flow rate is too fast, a large amount of dust will be generated when it hits the grouting material mixing equipment, which will pollute the environment in the factory and pose an extreme threat to the health of workers in severe cases; therefore, the existing technology requires a feeding device that can adjust the feeding flow rate and attract dust. Utility Model Content

[0006] A feeding device comprises: a prismatic bucket, a sealing plate mechanism, and a material discharge slope mechanism; the prismatic bucket is an inverted prism-shaped hollow shell structure with upper and lower openings, a sealing plate mechanism is provided at the material discharge port at the bottom of the prismatic bucket, the main body of the sealing plate mechanism is a sealing plate with a plate-like structure, the sealing plate is slidably fitted at the material discharge port of the prismatic bucket, a fixing frame is fixed to the bottom side wall of the prismatic bucket, the material discharge slope mechanism is rotatably fitted on the fixing frame, the main body of the material discharge slope mechanism is a material guide slope, the material guide slope is a slope structure with baffles on both sides, the upper end of the material guide slope is fixed to a deflection shaft, the deflection shaft is rotatably fitted on the fixing frame, a connecting rod is fixed on the deflection shaft, the other end of the connecting rod is rotatably fitted with the telescopic end of a second cylinder, and the non-telescopic end of the second cylinder adopts a hinge seat to rotatably fit on the side wall of the prismatic bucket.

[0007] Furthermore: in order to realize non-manual adjustment and closing of the speed and flow rate of the prismatic bucket discharge, the sealing plate mechanism also includes: a connecting frame, a cylinder frame, a first cylinder, and a connecting vertical plate; wherein the cylinder frame is fixed to the fixed frame by a connecting frame, the cylinder frame is fixed with the first cylinder, the telescopic end of the first cylinder is connected to the sealing plate through a connecting vertical plate, and a reinforcing rib is provided at the connection between the connecting vertical plate and the sealing plate.

[0008] Furthermore: In order to collect the dust generated during material discharge and prevent it from spreading and polluting the factory environment, a dust recovery mechanism is provided inside the prismatic bucket. The main body of the dust recovery mechanism is two groups of cavities arranged on the inner wall of the prismatic bucket, namely the first negative pressure chamber and the second negative pressure chamber. The first negative pressure chamber and the second negative pressure chamber are respectively provided with openings on the prismatic bucket to form a first connecting port and a second connecting port. The lower openings of the first negative pressure chamber and the second negative pressure chamber are flush with the material discharge port, so that a dust suction port is formed on each side of the material discharge port.

[0009] In order to generate negative pressure in the first negative pressure chamber and the second negative pressure chamber at the same time using only one set of negative pressure tubes, a connecting channel is used to connect the first negative pressure chamber and the second negative pressure chamber. The connecting channel is tightly attached to the side wall of the prismatic bucket, and an opening is provided on the prismatic bucket to form a third connecting port.

[0010] Further: In order to prevent materials from being mounted on the top of the first negative pressure chamber, the second negative pressure chamber, and the connecting channel, the height of the top of the first negative pressure chamber, the second negative pressure chamber, and the connecting channel close to the side of the prismatic bucket is higher than the height on the side away from the prismatic bucket, so that a slope structure is formed above the first negative pressure chamber, the second negative pressure chamber, and the connecting channel to prevent materials from being mounted on the top.

[0011] Furthermore: In order to allow the position of the negative pressure tube to be selected in different installation positions according to the actual installation environment, one group of the first connection port, the second connection port, and the third connection port is connected to a negative pressure tube, and the first connection port, the second connection port, or the third connection port of the other negative pressure tube that is not connected is sealed with a sealing plate.

[0012] Furthermore, in order to assist in material discharge and improve the smoothness of solid material discharge, a vibration motor is fixedly mounted on the side wall of the prismatic bucket.

[0015] In summary, the utility model has the following beneficial effects:

[0016] ① The feeding flow rate can be adjusted: when the powdered raw materials are directly discharged into the slurry mixing equipment, the flow rate is too fast, and a large amount of dust will be generated when hitting the slurry mixing equipment, which will pollute the environment in the factory and threaten the health of workers in serious cases. Therefore, it is necessary to use a material discharge slope mechanism to slowly guide the powdered raw materials to reduce their flow rate and impact force. At this time, the extension of the second cylinder is controlled by an external air path control mechanism, and the telescopic end of the second cylinder drives the deflection shaft to deflect through the connecting rod, thereby driving the material guide slope fixed on the deflection shaft to follow the deflection, and then the material guide slope receives the powdered raw materials falling from the feeding port, and transports the powdered raw materials to the slurry mixing equipment through the material guide slope, which can slow down the flow rate and impact force of the powdered raw materials to reduce their dust.

[0017] ② It can attract dust: when the speed is slowed down by the material discharge slope mechanism, if there is still a lot of dust, the negative pressure collection mechanism can be connected to the negative pressure tube at this time. The negative pressure tube generates suction negative pressure through the negative pressure collection mechanism. Because the first negative pressure chamber, the second negative pressure chamber and the connecting channel are connected, the negative pressure tube will cause negative pressure to be generated in the first negative pressure chamber and the second negative pressure chamber. Therefore, the dust suction ports under the first negative pressure chamber and the second negative pressure chamber will generate negative pressure attraction. Therefore, the raised dust will be attracted by the dust suction ports on both sides of the material discharge port. The attracted dust will be collected by the negative pressure collection mechanism connected to the negative pressure tube. The collected effective raw materials can continue to be put into the prismatic bucket for use to avoid waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The sealing plate mechanism 4 also includes: a connecting frame 41, a cylinder frame 42, a first cylinder 43, and a connecting vertical plate 44; wherein the cylinder frame 42 is fixed to the fixing frame 3 by the connecting frame 41, the cylinder frame 42 is fixed with the first cylinder 43, the telescopic end of the first cylinder 43 is connected with a sealing plate 45 through a connecting vertical plate 44, and a reinforcing rib is provided at the connection between the connecting vertical plate 44 and the sealing plate 45.

[0029] A dust recovery mechanism 2 is provided inside the prismatic bucket 1. The main body of the dust recovery mechanism 2 is two groups of cavities arranged on the inner wall of the prismatic bucket 1, namely a first negative pressure chamber 21 and a second negative pressure chamber 22. The first negative pressure chamber 21 and the second negative pressure chamber 22 are respectively provided with openings on the prismatic bucket 1 to form a first connecting port 26 and a second connecting port 27. The lower openings of the first negative pressure chamber 21 and the second negative pressure chamber 22 are flush with the discharge port 11, so that a dust suction port 23 is formed on each side of the discharge port 11.

[0030] The first negative pressure chamber 21 and the second negative pressure chamber 22 are connected by a connecting channel 24 , which is closely attached to the side wall of the prismatic bucket 1 . The connecting channel 24 is provided with an opening on the prismatic bucket 1 to form a third connecting port 28 .

[0031] The height of the top of the first negative pressure chamber 21, the second negative pressure chamber 22, and the connecting channel 24 close to the side of the prismatic bucket 1 is higher than the height of the side away from the prismatic bucket 1, so that a slope structure is formed above the first negative pressure chamber 21, the second negative pressure chamber 22, and the connecting channel 24 to prevent materials from being mounted on the top.

[0032] One of the first connection port 26 , the second connection port 27 , and the third connection port 28 is connected to the negative pressure tube 25 , and the other first connection port 26 , the second connection port 27 , or the third connection port 28 that is not connected to the negative pressure tube 25 is sealed by a sealing plate 29 .

[0033] A vibration motor 7 is fixedly mounted on the side wall of the prismatic bucket 1 .

[0034] A mounting frame 6 for fixing the prismatic bucket 1 is fixedly mounted on the fixing frame 3 .

[0035] The material guiding slope 52 is arranged on a side away from the first cylinder 43 .

[0036] Brief description of the usage process:

[0037] When in use, firstly, the first cylinder 43 and the second cylinder 53 are connected to an external pneumatic control mechanism, and the vibration motor 7 is connected to an external power supply with a switch; Figure 5As shown, the mounting frame 6 is used to fix the prismatic bucket 1 and the fixing frame 3 as a whole just above the grouting material mixing equipment. Generally, a plurality of groups of the utility model need to be arranged above the grouting material mixing equipment, and then the powdered grouting material raw materials (such as one or more of silicate cement, silica fume powder, nano calcium carbonate, and water reducer) are stored in the prismatic bucket 1; when it is necessary to feed the grouting material mixing equipment, the first cylinder 43 is controlled to contract, and the first cylinder 43 drives the sealing plate 45 to move through the connecting vertical plate 44, and the sealing plate 45 opens or partially opens the discharge port 11 of the prismatic bucket 1, and then the powdered grouting material raw materials in the prismatic bucket 1 fall from the channel opened by the discharge port 11 and enter the grouting material mixing equipment. When the amount of feeding reaches a specific amount, the first cylinder 43 is restarted to drive the sealing plate 45 to seal the discharge port 11.

[0038] When the powdered raw materials are directly discharged into the slurry mixing equipment, their flow rate is too fast, and a large amount of dust will be generated when they hit the slurry mixing equipment, which will pollute the environment in the factory and threaten the health of workers in serious cases. Therefore, it is necessary to use the discharge slope mechanism 5 to slowly guide the powdered raw materials to reduce their flow rate and impact force. At this time, the second cylinder 53 is extended by the external air path control mechanism, and the telescopic end of the second cylinder 53 drives the deflection shaft 51 to deflect through the connecting rod 55, thereby driving the guide slope 52 fixed on the deflection shaft 51 to follow the deflection, and then the guide slope 52 receives the powdered raw materials falling from the discharge port 11, and transports the powdered raw materials to the slurry mixing equipment through the guide slope 52, which can slow down the flow rate and impact force of the powdered raw materials to reduce their dust.

[0039] According to the above principle, the slope of the material guide slope 52 can be changed by adjusting the extension amount of the second cylinder 53. For example, when the flow rate of the powder raw material is too large, the second cylinder 53 can be further extended to make the slope of the material guide slope 52 smaller. A smaller slope can further slow down the flow rate of the powder raw material. Therefore, the slope of the material guide slope 52 can be appropriately adjusted according to actual conditions.

[0040] After the speed is slowed down by the discharge slope mechanism 5, if there is still a lot of dust, the negative pressure collection mechanism can be connected to the negative pressure pipe 25 at this time. The negative pressure pipe 25 generates suction negative pressure through the negative pressure collection mechanism. Because the first negative pressure chamber 21, the second negative pressure chamber 22 and the connecting channel 24 are conductively connected, the negative pressure pipe 25 will cause negative pressure to be generated in the first negative pressure chamber 21 and the second negative pressure chamber 22. Therefore, the dust suction port 23 under the first negative pressure chamber 21 and the second negative pressure chamber 22 will generate negative pressure attraction. Therefore, the raised dust will be attracted by the dust suction port 23 on both sides of the discharge port 11, and the attracted dust will be collected by the negative pressure collection mechanism connected to the negative pressure pipe 25. The collected effective raw materials can continue to be put into the prismatic bucket 1 for use to avoid waste of resources.

[0041] When the powder raw material in the prismatic bucket 1 is not discharged smoothly, the power supply of the vibration motor 7 can be turned on. The vibration motor 7 works and transmits vibration to the powder raw material through the side wall of the prismatic bucket 1 to ensure the smoothness of the raw material discharge.

[0042] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
