Description

Technical Field

[0001] This utility model relates to the field of dispensing devices, and more specifically, to a device for precisely dispensing concrete additives. Background Technology

[0002] Concrete additives are chemical substances added during the concrete mixing process that can significantly improve the performance of concrete. Concrete additives are characterized by a wide variety of types, small dosages, and a significant impact on concrete performance. They are characterized by low investment, quick results, and significant technical and economic benefits. With the continuous advancement of science and technology, additives have been increasingly used and have become the fifth important component of concrete in addition to the four basic components. Furthermore, additives have a certain effect on improving the carbonation resistance of concrete.

[0003] A search revealed that Chinese patent CN219153301U discloses a "concrete additive dispensing device." This device includes a conveying pipe on a mixing tank, connected to a storage cylinder. One end of the storage cylinder is movably connected to the conveying pipe, while the other end has a threaded hole through which a threaded rod passes. The threaded rod is fixedly connected to a piston inserted into the storage cylinder. When the user needs to add liquid additive to the mixing concrete, they first rotate the threaded rod through the threaded hole. This pushes the piston, forcing the additive from the storage cylinder into the conveying pipe, where it then falls into the mixing tank. The user can visually adjust the dosage by observing the scale on the storage cylinder and the threaded rod, thus improving the accuracy of additive dispensing. However, the device still has the following drawbacks:

[0004] (1) Existing feeding devices can only feed in different directions by adjusting the direction of the discharge pipe, but the discharge pipe cannot be directly inserted into the concrete mixing equipment, which reduces the accuracy of feeding.

[0005] (2) The existing dispensing device has a fixed position, which makes it inconvenient to quickly apply to concrete mixing equipment of different sizes and models, thus reducing the versatility of the dispensing device.

[0006] Therefore, we have made improvements to this and proposed a precise concrete additive dispensing device. Utility Model Content

[0007] The purpose of this invention is to address the problem that existing dispensing devices can only dispense materials in different directions by adjusting the direction of the discharge pipe, but the discharge pipe cannot directly extend into the concrete mixing equipment, which reduces the accuracy of dispensing. Furthermore, the fixed position of the existing dispensing device makes it inconvenient to quickly apply to concrete mixing equipment of different sizes and models, thus reducing the versatility of the dispensing device.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A precise dispensing device for concrete additives is proposed to improve the aforementioned problems.

[0010] The present invention is as follows:

[0011] The device includes a feeding tank, which has an inlet at its upper end, clamping components on both sides of the tank, a connecting pipe fixedly installed at the lower end of the tank, and a feeding component at the lower end of the connecting pipe.

[0012] The clamping assembly includes outer plates installed on the outer walls of both ends of the feeding tank, and an inner groove is opened inside the outer plate at the end near the feeding tank.

[0013] The feeding assembly includes a groove inside the connecting pipe, a discharge pipe rotatably disposed inside the groove, an annular groove on the side wall of the groove, and a limiting ring that cooperates with the annular groove on the side wall of the discharge pipe.

[0014] As a preferred technical solution of this utility model, a first conical gear is provided on the inner wall of the front end of the inner groove, and a first motor is connected to the front end of the first conical gear. A second conical gear is provided on the inner wall of the inner groove away from the feeding tank, which cooperates with the first conical gear.

[0015] As a preferred technical solution of this utility model, a sliding groove is provided on the outer side of the inner groove near the second bevel gear, and a screw connected to the second bevel gear is provided inside the sliding groove. A sliding plate is fitted on the outer wall of the screw, and a clamp is installed on the outer wall of the sliding plate away from the feeding tank.

[0016] As a preferred technical solution of this utility model, the side wall of the slide groove is provided with a limiting groove, and the side wall of the slide plate is provided with a limiting plate that cooperates with the limiting groove.

[0017] As a preferred technical solution of this utility model, a toothed ring is fitted on the outer wall of the discharge pipe at the lower end of the limiting ring, a fixing plate is fixedly installed on the outer wall of the right end of the connecting pipe, a toothed disc is provided at the lower end of the fixing plate to cooperate with the toothed ring, and a second motor is connected to the upper end of the toothed disc.

[0018] As a preferred technical solution of this utility model, a bottom pipe is connected to the lower outer wall of the discharge pipe, and a feeding port communicating with the bottom pipe is opened on the lower side wall of the bottom pipe.

[0019] As a preferred technical solution of this utility model, the upper end of the tube groove is connected to the lower end of the inlet.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In the solution of this utility model:

[0022] 1. By using a set of first bevel gear, second bevel gear, screw, slide plate, clamping plate and limiting plate, when it is necessary to add additives to concrete mixing equipment of different sizes, the operation of the first motor on both sides drives the first bevel gear connected to it to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the screw connected to it to rotate. Through the engagement of the outer wall thread, the slide plate is driven to slide in the slide groove. Under the limiting plate embedded in the limiting groove, the clamping plates on both sides can be adjusted according to the diameter of the concrete mixing tank, so that the feeding device can be installed efficiently and conveniently on the upper side of different concrete tanks, improving the versatility of the feeding device.

[0023] 2. By using a limiting ring, toothed ring, toothed disc, and bottom pipe, precise addition of additives to the concrete mixing tank can be achieved. The second motor is controlled to rotate, driving the connected toothed disc to rotate. This, in turn, drives the toothed ring to rotate. With the limiting ring embedded in the groove, the discharge pipe rotates stably within the groove, thereby causing the bottom pipe connected to the lower end to rotate around the center of the connecting pipe. This adjusts the direction of the feeding port, efficiently and stably adjusting the feeding position and improving the accuracy and ease of operation of the feeding device.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] like Figure 1-5 As shown, this embodiment proposes a precise concrete additive dosing device, including a feeding tank 1. The upper end of the feeding tank 1 is provided with a feeding port 2. Clamping components are provided on both sides of the feeding tank 1. A connecting pipe 4 is fixedly installed at the lower end of the feeding tank 1. A feeding component is provided at the lower end of the connecting pipe 4.

[0036] The clamping assembly includes an outer plate 301 installed on the outer wall of both ends of the feeding tank 1, and an inner groove 302 is opened in the inner part of the outer plate 301 near the feeding tank 1.

[0037] The feeding assembly includes a groove 501 inside the connecting pipe 4, a discharge pipe 502 rotatably disposed inside the groove 501, an annular groove 503 on the side wall of the groove 501, and a limiting ring 504 that cooperates with the annular groove 503 on the side wall of the discharge pipe 502.

[0038] like Figure 3 As shown, a first bevel gear 303 is provided on the inner wall of the front end of the inner groove 302. A first motor 304 is connected to the front end of the first bevel gear 303. A second bevel gear 305 is provided on the inner wall of the inner groove 302 away from the feeding tank 1, which cooperates with the first bevel gear 303. The operation of the first motors 304 on both sides is controlled to drive the first bevel gear 303 connected to it to rotate, and the meshing drives the second bevel gear 305 to rotate, which in turn drives the screw 307 connected to it to rotate.

[0039] like Figure 3 As shown, the inner groove 302 has a sliding groove 306 on the outer side near the second bevel gear 305. The sliding groove 306 is provided with a screw 307 that is connected to the second bevel gear 305. A sliding plate 308 is fitted on the outer wall of the screw 307. A clamping plate 309 is installed on the outer wall of the sliding plate 308 away from the feeding tank 1. When the screw 307 rotates, the sliding plate 308 is driven to slide in the sliding groove 306 through the thread engagement of the outer wall. Under the limitation of the limiting plate 311 embedded in the limiting groove 310, the clamping plates 309 on both sides can be adjusted according to the diameter of the concrete mixing tank.

[0040] like Figure 3 As shown, the side wall of the chute 306 is provided with a limiting groove 310, and the side wall of the slide plate 308 is provided with a limiting plate 311 that cooperates with the limiting groove 310. Under the limiting of the limiting plate 311 embedded in the limiting groove 310, the spacing of the two side clamps 309 can be adjusted according to the diameter of the concrete mixing tank, so as to efficiently and conveniently install the feeding device on the upper side of different concrete tanks.

[0041] like Figure 4 As shown, a toothed ring 505 is fitted onto the outer wall of the discharge pipe 502 at the lower end of the limiting ring 504. A fixing plate 506 is fixedly installed on the outer wall of the right end of the connecting pipe 4. A toothed disc 508 that meshes with the toothed ring 505 is provided at the lower end of the fixing plate 506. A second motor 507 is connected to the upper end of the toothed disc 508. The second motor 507 is controlled to rotate, thereby driving the toothed disc 508 connected to it to rotate, which in turn drives the toothed ring 505 to rotate.

[0042] like Figure 2As shown, the lower outer wall of the discharge pipe 502 is connected to a bottom pipe 509. The lower side wall of the bottom pipe 509 has a feeding port 510 that communicates with the bottom pipe 509. The discharge pipe 502 rotates stably in the pipe groove 501, thereby driving the bottom pipe 509 connected to the lower end to rotate around the center of the connecting pipe 4, adjusting the direction of the feeding port 510, and efficiently and stably adjusting the feeding position.

[0043] like Figure 5 As shown, the upper end of the tube groove 501 is connected to the lower end of the inlet 2. The outlet pipe 502 rotates stably in the tube groove 501, thereby driving the bottom pipe 509 connected at the lower end to rotate around the center of the connecting pipe 4, adjusting the direction of the feeding port 510, and efficiently and stably adjusting the feeding position, thus improving the feeding accuracy and operation convenience of the feeding device.

[0044] Specifically, when using this dispensing device: When additives need to be added to concrete mixing equipment of different sizes, the first motors 304 on both sides are controlled to rotate, driving the first bevel gear 303 connected to them to rotate. This meshes with the second bevel gear 305, which in turn drives the screw 307 connected to it to rotate. Through the engagement of the outer wall threads, the sliding plate 308 slides within the sliding groove 306. With the limiting plate 311 embedded in the limiting groove 310, the spacing between the two clamping plates 309 is adjusted according to the diameter of the concrete mixing tank, thus facilitating the dispensing of materials. The device can be installed efficiently and conveniently on the upper side of different concrete tanks. When it is necessary to accurately add the mixture to the desired position in the concrete mixing tank, the second motor 507 is controlled to drive the connected gear disc 508 to rotate, which in turn drives the gear ring 505 to rotate. With the limit ring 504 embedded in the ring groove 503, the discharge pipe 502 can rotate stably in the pipe groove 501, thereby driving the bottom pipe 509 connected to the lower end to rotate around the center of the connecting pipe 4, adjusting the direction of the feeding port 510, and efficiently and stably adjusting the feeding position.
