Description
Technical Field
[0001] The present application relates to the technical field of concrete mixing tanks, and in particular to an admixture feeding device for concrete adaptation. Background Art
[0002] Concrete is a general term for engineering materials that combine cementitious materials and aggregates into a whole. Common concrete refers to cement as a cementitious material, sand and stone as aggregates, mixed with water, admixtures and additives in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering.
[0003] A common mixing tank includes a tank body, a stirring rod rotatably arranged in the tank body, and stirring blades arranged on the stirring rod. A feeding port is provided on the mixing tank. Technicians weigh additives, sand, stone and other aggregates and put them into the feeding port for mixing.
[0004] Regarding the above-mentioned related technologies, admixtures, sand, gravel, water, etc. are often fed into the mixing tank through a feed port. Regardless of whether the solid or liquid is fed first, the solid remaining at the feed port is easy to contact and agglomerate with the liquid, affecting the subsequent feeding efficiency and reducing the preparation accuracy of the concrete. Therefore, this needs to be improved. Utility Model Content
[0005] In order to reduce agglomeration during feeding and improve the preparation accuracy of concrete, the present application provides a concrete-adaptive admixture feeding device.
[0006] The present application provides a concrete adaptation admixture feeding device adopting the following technical solution:
[0007] A feeding device for admixture adaptation of concrete comprises a tank body and a mixing body arranged in a mixing tank, a feeding port is opened on the side wall of the tank body, a feeding assembly is arranged at the feeding port, the feeding assembly comprises a mounting frame arranged on the outer side wall of the tank body and a feeding barrel arranged on the mounting frame and extending into the feeding port, a partition is arranged in the feeding barrel, the layout direction of the partition is consistent with the axial direction of the feeding barrel, the partition divides the feeding barrel into a first feeding chamber and a second feeding chamber, the feeding barrel is rotatably arranged on the mounting frame, and the mounting frame is also provided with an adjusting member for rotationally adjusting the feeding barrel.
[0008] By adopting the above technical solution, when concrete needs to be prepared, the technician first feeds an admixture into the tank body through the first feeding chamber of the feeding barrel. Then, when different types of admixtures need to be added, the technician rotates the feeding barrel through the adjusting piece to rotate the second feeding chamber to a position convenient for adding the admixture. At this time, the technician passes another admixture into the tank body through the second feeding chamber for mixing and stirring, thereby realizing the separate addition of different types of admixtures and the step-by-step addition of solid admixtures and liquid admixtures, reducing the agglomeration generated during solid-liquid mixing, thereby reducing the problem of clogging the feeding port caused by this, and improving the preparation efficiency and preparation accuracy of concrete.
[0009] Optionally, the adjusting member includes an adjusting block arranged on the mounting frame, an adjusting groove is opened on the outer peripheral wall of the feeding barrel, the opening direction of the adjusting groove is consistent with the circumference direction of the feeding barrel, the adjusting block is slidably adapted to the adjusting groove, and the feeding barrel is also provided with a limit member for limiting the rotation position of the feeding barrel.
[0010] By adopting the above technical solution, when it is necessary to rotate the feeding barrel, the technician directly rotates the feeding barrel. At this time, the adjusting block on the mounting frame is slidably matched with the adjusting groove. Since the adjusting groove is a circular groove opened along the outer peripheral wall of the feeding barrel, at this time, under the limit of the adjusting block, the feeding barrel can be stably rotated and adjusted, and it is not easy to deviate. At the same time, the limit member is set to limit the rotation position of the feeding barrel, so as to realize the stable connection between the first feeding chamber and the second feeding chamber and the feeding port, so that the feeding barrel is not easy to rotate when feeding, thereby reducing the leakage caused by the rotation of the feeding barrel.
[0011] Optionally, a limiting groove is provided on the inner bottom wall of the adjustment groove, and the limiting member includes a limiting block elastically arranged in the limiting groove, a clamping groove is provided on the side of the adjustment block that is in contact with the adjustment groove, and the limiting block is movably inserted into the clamping groove.
[0012] By adopting the above technical solution, when the feeding barrel is rotated to the point where the first feeding chamber corresponds to the feeding port, the position of the limit block corresponds to the clamping groove, and the limit block automatically pops out in the direction of the clamping groove under the action of the elastic restoring force, thereby locking the limit block and the clamping groove and achieving the stability of feeding from the first feeding chamber; when adding another additive, the technician rotates the feeding barrel, and when the feeding barrel is rotated to the point where the second feeding chamber corresponds to the feeding port, the limit block corresponds to the clamping groove, and the limit block automatically pops out under the action of the elastic restoring force, thereby achieving stability when feeding from the second feeding chamber.
[0013] Optionally, one end of the limit block that is movably inserted into the clamping groove is in an arc shape, and the arc surface side of the limit block is movably pressed against the inner side wall of the clamping groove.
[0014] By adopting the above technical solution, when the feeding barrel needs to be rotated, since the end side of the limit block is in the shape of an arc, when the feeding barrel is rotated, the end side of the limit block is tightly pressed against the inner wall of the clamping groove, and the limit block is immersed in the limit groove under the action of the elastic compression force, thereby realizing the separation of the limit block and the clamping groove, which facilitates the rotation of the feeding barrel; and the limit block is set to be in the shape of an arc, which facilitates the rotation of the feeding barrel, and the position of the feeding barrel can be limited after the limit block is inserted into the clamping groove.
[0015] Optionally, a sliding groove is provided on the mounting frame, and the adjustment block is slidably arranged in the sliding groove, and a positioning member for limiting the position of the adjustment block is also provided on the mounting frame.
[0016] By adopting the above technical solution, when a large amount of aggregate / cementitious materials such as sand, gravel, cement, etc. are needed to be fed, the first feeding chamber and the second feeding chamber will affect the feeding efficiency. Therefore, the technician can slide the feeding cylinder to separate the feeding cylinder from the feeding port to expose the feeding port, thereby realizing the feeding of a large amount of aggregate and cementitious materials, which is suitable for feeding in different situations.
[0017] Optionally, a positioning groove is provided on the side wall of the adjustment block, and a positioning hole connected with the sliding groove is provided on the side wall of the mounting frame. The positioning member includes a positioning rod elastically arranged in the positioning hole, and the positioning rod movably passes through the positioning hole and is inserted into the positioning groove, and the end side of the positioning rod is tightly pressed against the inner side wall of the positioning groove.
[0018] By adopting the above technical solution, when the feeding cylinder is slid to separate the feeding cylinder from the feeding port, the elastically arranged positioning rod is inserted into the positioning groove. At this time, the feeding cylinder is not easy to slide relative to each other, thereby limiting the position of the feeding cylinder, thereby achieving stable feeding of the feeding cylinder or stable feeding directly at the feeding port.
[0019] Optionally, the end side of the positioning rod that is tightly pressed against the inner side wall of the positioning groove is spherical.
[0020] By adopting the above technical solution, the positioning rod is set to a spherical shape, which is convenient for technicians to slide and adjust the position of the feeding barrel. At the same time, the positioning rod can also achieve stable limiting of the feeding barrel.
[0021] Optionally, the mounting frame is rotatably mounted on the tank body, and a baffle is also provided on the mounting frame. When the feeding tube is inserted into the feeding port, the baffle is tightly pressed against the outer peripheral wall of the tank body.
[0022] By adopting the above technical solution, when the feeding cylinder is not used for feeding or the feeding cylinder needs to be fully cleaned, the technician rotates the mounting frame to separate the feeding cylinder from the feeding port; when the feeding cylinder is used for feeding, the technician rotates the mounting frame to insert the feeding cylinder into the feeding port. At this time, the feeding cylinder under the action of the baffle is not easy to rotate away from the tank body, thereby achieving stable splicing of the feeding cylinder and the tank body and stable feeding. And when feeding, the baffle plays a certain supporting role.

DETAILED DESCRIPTION
[0031] The following is combined with Figure 1-3 This application is described in further detail.
[0032] The following is combined with Figure 1-3 This application is described in further detail.
[0033] The embodiment of the present application discloses a device for feeding concrete-adapting admixture. Figure 1 A concrete adaptation admixture feeding device includes a vertically arranged tank body 1 and a stirring body 11 coaxially rotatably arranged in the tank body 1. The stirring body 11 includes a stirring rod rotatably arranged in the tank body 1 and a plurality of stirring blades fixed on the stirring rod. A driving member 12 for rotating the stirring body 11 is fixedly connected to the top side of the tank body 1. In the present application, the driving member 12 is a rotating motor.
[0034] A feeding port 13 is provided on the top side of the tank body 1. The height of the feeding port 13 is higher than the highest stirring blade, and the feeding port 13 is arranged obliquely. An upper hopper is fixed at the feeding port 13, and a feeding assembly 2 is also provided on the tank body 1. The feeding assembly 2 includes a mounting frame 14 provided on the tank body 1 and a feeding barrel 21 provided on the mounting frame 14. The mounting frame 14 includes two parallel mounting rods. The feeding barrel 21 is movably inserted into the feeding port 13, and the feeding barrel 21 is fixedly connected to a partition 22. The arrangement direction of the partition 22 is parallel to the axial direction of the feeding barrel 21. The partition 22 divides the opening of the feeding barrel 21 into a first feeding chamber 221 and a second feeding chamber 222 of the same opening size, and the feeding barrel 21 is rotatably provided on the mounting frame 14. The mounting frame 14 is also provided with an adjusting member 23 for rotating and adjusting the feeding barrel 21.
[0035] Reference Figure 1 and Figure 2 The adjusting member 23 includes an adjusting block 231 arranged on the mounting frame 14, and an adjusting groove 232 is opened on the outer peripheral wall of the feeding barrel 21. The adjusting groove 232 is arranged in a circular shape. The end side of the adjusting block 231 close to the feeding barrel 21 is in contact with the inner bottom wall of the adjusting groove 232, and the adjusting block 231 is slidably adapted to the adjusting groove 232.
[0036] Since the feeding cylinder 21 is not easy to rotate when needed during feeding, the first feeding chamber 221 / the second feeding chamber 222 is stably located at a position convenient for feeding, and a limiting member 24 for limiting the position of the feeding cylinder 21 is also provided on the feeding cylinder 21. Figure 2 and Figure 3A limiting groove is provided on the inner bottom wall of the adjusting groove 232, and the limiting member 24 includes a limiting block 241 elastically set in the limiting groove, and a limiting spring 242 is fixedly connected to the limiting block 241, one end of the limiting spring 242 is fixed to the limiting block 241, and the other end of the limiting spring 242 is fixed to the inner bottom wall of the limiting groove, and a clamping groove 243 is provided on the adjusting block 231, and one end of the limiting block 241 away from the inner bottom wall of the limiting groove is inserted into the clamping groove 243.
[0037] There are two groups of limit grooves and limit blocks 241, and the two groups of limit grooves are arranged opposite to each other. The two groups of limit grooves correspond one to one to the opposite sides of the mounting frame 14. Therefore, when feeding is needed, the technician rotates the feeding barrel 21 to the first feeding chamber 221 corresponding to the feeding port 13. At this time, the limit block 241 corresponds to the position of the clamping groove 243. The limit block 241 automatically pops out in the direction of the clamping groove 243 under the action of the elastic restoring force, thereby achieving the locking of the limit block 241 and the clamping groove 243, and achieving the stability of feeding from the first feeding chamber 221; when adding another additive, the technician rotates the feeding barrel 21. At this time, when the feeding barrel 21 rotates to the second feeding chamber 222 corresponding to the feeding port 13, the limit block 241 corresponds to the clamping groove 243. At this time, the limit block 241 automatically pops out under the action of the elastic restoring force, thereby achieving stability when feeding from the second feeding chamber 222.
[0038] At the same time, in order to facilitate the adjustment operation of the limit block 241, the end of the limit block 241 close to the clamping groove 243 is spherical, and the spherical end side of the limit block 241 is tightly pressed against the inner wall of the clamping groove 243. When the feeding barrel 21 needs to be rotated, since the end side of the limit block 241 is arc-shaped, when the feeding barrel 21 is rotated, the end side of the limit block 241 is tightly pressed against the inner wall of the clamping groove 243, and the limit block 241 is immersed in the limit groove under the action of the elastic compression force, thereby realizing the separation of the limit block 241 and the clamping groove 243, which is convenient for the rotation of the feeding barrel 21; and the limit block 241 is set to be in an arc shape, which is convenient for the rotation of the feeding barrel 21, and the limit block 241 can also be inserted into the clamping groove 243 to limit the position of the feeding barrel 21.
[0039] In some cases, when a large amount of raw materials such as cement, sand and gravel are fed, the first feeding chamber 221 and the second feeding chamber 222 cannot meet the efficiency requirements of a large amount of feeding. Therefore, it is necessary to slide the feeding tube 21 to a position separated from the feeding port 13. At this time, in order to facilitate this operation, sliding grooves 141 are opened on the side walls of the mounting frame 14 on both sides that are close to each other. The opening direction of the sliding groove 141 is consistent with the extension direction of the mounting frame 14, and the sliding groove 141 is open at one end away from the tank body 1. The adjusting block 231 is slidably arranged in the sliding groove 141, and the mounting frame is also provided with a positioning member 25 for limiting the sliding position of the adjusting block 231.
[0040] Reference Figure 3 A positioning hole 253 connected to the sliding groove 141 is provided on the side wall of the mounting frame 14, and the positioning member 25 includes a positioning rod 251 elastically arranged in the positioning hole 253, one end of the positioning rod 251 is fixedly connected to a positioning spring 252, and the end of the positioning spring 252 away from the connection with the positioning rod 251 is fixedly connected to the inner bottom wall of the positioning hole 253, and a positioning groove 254 is provided on the side wall of the adjusting block 231 that is in contact with the inner bottom wall of the sliding groove 141, and one end of the positioning rod 251 that movably passes through the positioning hole 253 is movably inserted into the positioning groove 254, and the end of the positioning rod 251 inserted into the positioning groove 254 is also in an arc shape.
[0041] At the same time, there are two groups of positioning rods 251 and positioning holes 253. The two groups of positioning rods 251 are arranged along the extension direction of the mounting frame 14. When a large amount of aggregate / cementitious materials such as sand, gravel, and cement are needed for feeding, the existence of the first feeding chamber 221 and the second feeding chamber 222 will affect the feeding efficiency. Therefore, the technician can slide the feeding barrel 21 to separate the feeding barrel 21 from the feeding port 13 to expose the feeding port 13, thereby realizing the feeding of a large amount of aggregate and cementitious materials. It is suitable for feeding in different situations. The positioning rod 251 is set to a spherical shape, which is convenient for the technician to slide and adjust the position of the feeding barrel 21. At the same time, the positioning rod 251 can also achieve stable limiting of the feeding barrel 21.
[0042] Furthermore, when it is necessary to clean the feeding barrel 21 separately, it is troublesome for the technicians to remove the feeding barrel 21 for cleaning. If the feeding barrel 21 is directly rotated to a position separated from the feeding port 13, it can not only reduce the time for the technicians to disassemble the feeding barrel 21, but also simplify the cleaning operation. Therefore, in order to achieve this purpose, the mounting frame 14 is rotatably arranged on the tank body 1, and a baffle 15 is provided on the mounting frame 14. The baffle 15 is arranged in an arc shape, and the baffle 15 is movably pressed against the side wall of the upper hopper of the tank body 1. After the feeding barrel 21 is inserted into the feeding port 13, the feeding barrel 21 can bear the weight when feeding the additive when needed. The baffle 15 fits with the upper hopper, which can not only stably insert the feeding barrel 21 into the feeding port 13, but also realize the bearing of the feeding barrel 21 when feeding the additive.
[0043] The implementation principle of the concrete adaptation admixture feeding device of the embodiment of the present application is as follows: when feeding a large amount of materials, the technician rotates the mounting frame 14 to separate the feeding cylinder 21 from the feeding port 13, and then directly feeds a large amount of raw materials at the upper hopper;
[0044] When feeding different kinds of additives, the technician rotates the mounting frame 14 to insert the feeding barrel 21 into the feeding port 13. At this time, the baffle 15 is stably fitted and pressed against the side wall of the upper hopper. The technician then rotates the feeding barrel 21 to position the first feeding chamber 221 for feeding convenience. The limit block 241 is then inserted into the clamping groove 243 to limit the position of the feeding barrel 21.
[0045] When feeding another additive, the technician rotates the feeding barrel 21 to position the second feeding chamber 222 for feeding. At this time, the limit block 241 is also inserted into the clamping groove 243 to limit the position of the feeding barrel 21, thereby facilitating feeding of another additive.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
