Description

Technical Field

[0001] This utility model relates to the technical field of material conveying devices, specifically a rapid material conveying device for concrete processing. Background Technology

[0002] In concrete processing, material conveying plays a crucial role. It is responsible for accurately and continuously transporting raw materials such as aggregates (like sand and stone), cement, water, and additives to the mixing equipment in precise proportions, ensuring the accuracy of the concrete mix design. An efficient material conveying system reduces material loss and contamination during transport, guaranteeing consistent concrete quality. Simultaneously, it improves production efficiency, reduces labor costs, and enables automated and continuous concrete processing. Furthermore, a well-designed material conveying layout optimizes the production process, reduces equipment footprint, and enhances the cleanliness and safety of the overall production environment.

[0003] Utility model patent CN221369232U discloses a material conveying mechanism for concrete preparation, which includes a support and a conveying pipe. A universal joint is connected to the side wall of the discharge end of the conveying pipe. The universal joint is an elastic flexible hose, and its end wall is detachably connected to the side wall of the discharge end of the conveying pipe. The material to be transported enters the interior of the conveying pipe from the feed hopper, and the conveying component transports the material to the discharge end of the conveying pipe, where it is discharged from the universal joint. The operator can adjust the position of the universal joint according to actual needs, thereby adjusting the position and direction of the material discharge, thus improving the efficiency of material transportation and the convenience of material storage.

[0004] Although the aforementioned conveying mechanism can adjust the material dropping position through the universal joint, the universal joint is a flexible structure and lacks fixing measures. As a result, it will swing under the impact of the material, causing the material dropping position to deviate. It needs to be fixed by hand by the staff throughout the material dropping process, which is inconvenient to use and wastes manpower. In addition, since the universal joint has multiple pleats, material is very easy to accumulate in the pleats, making subsequent cleaning work difficult. Therefore, in order to address the above problems, a rapid material conveying device for concrete processing is proposed. Utility Model Content

[0005] To address the technical problems of material conveying devices in comparative technologies, which require manual operation by workers, resulting in significant waste of manpower and potential danger, as well as the ease with which materials accumulate in the folds inside the pipes and are difficult to clean, this utility model provides a rapid material conveying device for concrete processing.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A rapid material conveying device for concrete processing includes a screw feeder with a guide pipe assembly sleeved on its discharge pipe, and an adjustable pipe end fixing frame for supporting the bottom end of the guide pipe assembly at the bottom of the screw feeder; wherein, the adjustable pipe end fixing frame includes an end seat, a rotatably connected guide rod is mounted on its lower end face, and corner fixing clamps for clamping the guide rod are mounted on both sides of the end seat, a height adjusting cylinder is slidably mounted on the guide rod, and a support rod frame connected to the bottom end of the guide pipe assembly is movably mounted on it.

[0008] In one possible implementation, the conduit assembly includes a tube seat to which a flexible conduit sleeved outside the discharge pipe of the screw feeder is connected, and also includes a clamp for fixing the flexible conduit to the discharge pipe.

[0009] In one possible implementation, the flexible conduit includes a straight section with a stacked section on its upper part, the top of which is fixedly connected to an installation ring, which is bolted to a pipe seat.

[0010] In one possible implementation, the guide rod includes a rotating seat rotatably connected to the end seat, with a rib fixedly connected to its bottom end.

[0011] In one possible implementation, the corner fixing clamp includes an adjusting screw threaded to the end seat, with a clamping block rotatably connected to its end, and symmetrically arranged guide shafts slidably connected to the end seat fixed on the back of the clamping block.

[0012] In one possible implementation, the height adjusting cylinder includes a sleeve slidably fitted onto the rib, on which a threaded locking screw is provided, and a friction plate is rotatably connected to the end of the locking screw. A locking groove for accommodating the friction plate is provided on the rib.

[0013] In one possible implementation, guide tubes are fixedly provided on both sides of the sleeve, and the support rod frame includes a threaded rod slidably disposed in the guide tube, with a ring frame fixedly connected to its end.

[0014] In one possible implementation, both ends of the guide cylinder are provided with locking wheels that are threadedly connected to the threaded rod.

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

[0016] In the adjustable pipe end fixing bracket, the end of the guide tube assembly is fixed by the support rod bracket. The bending degree of the guide tube assembly can be changed by sliding back and forth. At the same time, the height adjustment cylinder can drive the support rod bracket to move up and down, thereby adjusting the setting height of the bottom end of the guide tube assembly. Finally, since the guide rod can rotate freely, it can drive the support rod bracket to rotate, causing the end of the guide tube assembly to shift. In summary, the end of the guide tube assembly can be fixed within a height-adjustable circular range to meet different material dropping requirements. Moreover, no worker assistance is required to fix it after adjustment, making it extremely convenient to use.

[0017] In addition, for flexible conduits, the part used for guiding materials is a straight pipe section with a smooth inner wall that makes it difficult for materials to accumulate. Although the stacked section formed by stacking on top has multiple sets of folds, it is also difficult for materials to accumulate because it does not directly contact the materials, making it easy to clean later. Furthermore, the length of the straight pipe section can be changed by releasing the pipe body of the stacked section or by further stacking the pipe body to meet different material discharge requirements.

Detailed Implementation

[0025] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0026] like Figure 1 - Figure 2 As shown in the figure, this embodiment provides a material rapid conveying device for concrete processing, including a screw feeder 1, whose discharge pipe is fitted with a guide tube assembly 2, and an adjustable pipe end fixing frame 3 for supporting the bottom end of the guide tube assembly 2 is provided at the bottom of the screw feeder 1; wherein, the adjustable pipe end fixing frame 3 includes an end seat 31, a guide rod 32 rotatably connected to its lower end face is installed, and corner fixing clamps 33 for clamping the guide rod 32 are installed on both sides of the end seat 31, a height adjusting cylinder 34 is slidably provided on the guide rod 32, and a support rod frame 35 connected to the bottom end of the guide tube assembly 2 is movably installed on it.

[0027] Based on the above structural scheme, the end of the guide tube assembly 2 is fixed by the support rod frame 35, which can change the bending degree of the guide tube assembly 2 by sliding back and forth. At the same time, the height adjustment cylinder 34 can drive the support rod frame 35 to move up and down, thereby adjusting the setting height of the bottom end of the guide tube assembly 2. Finally, since the guide rod 32 can rotate freely, it can drive the support rod frame 35 to rotate, causing the end of the guide tube assembly 2 to shift. In summary, the end of the guide tube assembly 2 can be fixed within a height-adjustable circular range to meet different material dropping requirements. Moreover, no worker assistance is required for fixing after adjustment, making it extremely convenient to use.

[0028] Among them, such as Figure 4 As shown, the guide rod 32 includes a rotating seat 321 rotatably connected to the end seat 31, and a rib 322 fixedly connected to its bottom end. The corner fixing clamp 33 includes an adjusting screw 332 threadedly connected to the end seat 31, and a clamping block 331 rotatably connected to its end. A guide shaft 333 symmetrically arranged and slidably connected to the end seat 31 is fixedly provided on the back of the clamping block 331. In the above structure, since the rotating seat 321 is rotatably connected to the end seat 31, the rib 322 can rotate freely about the rotating seat 321. When the rib 322 rotates to the required angle and needs to be fixed, the clamping block 331 can be clamped by turning the adjusting screw 332 to restrict its rotation, thereby completing the fixation of the rotation angle of the rib 322.

[0029] like Figure 4 - Figure 5As shown, the height adjusting cylinder 34 includes a sleeve 341 slidably sleeved on the rib 322, on which a threaded locking screw 342 is provided. A friction plate 343 is rotatably connected to the end of the locking screw 342. A locking groove 323 for accommodating the friction plate 343 is provided on the rib 322. Based on the above structural scheme, the sleeve 341 can slide up and down along the rib 322. When it is necessary to fix the height of the sleeve 341, the friction plate 343 can be controlled by the locking screw 342 to fit tightly against the locking groove 323, and the sleeve 341 and the rib 322 are fixedly connected by compression friction.

[0030] Guide cylinders 344 are fixedly installed on both sides of the sleeve 341. The support rod frame 35 includes a threaded rod 351 that is slidably installed in the guide cylinder 344, and a ring frame 352 is fixedly connected to its end. In addition, locking wheels 345 that are threadedly connected to the threaded rod 351 are provided at both ends of the guide cylinder 344. In the above structural scheme, the support structure formed by the ring frame 352 and the threaded rod 351 can fix and support the end of the conduit assembly 2. At the same time, since the threaded rod 351 is slidably connected to the guide cylinder 344, its support length can be changed. After the support length is adjusted, the position of the threaded rod 351 can be locked and fixed by the locking wheel 345 to prevent it from sliding again and changing the support length.

[0031] like Figure 3 As shown, the conduit assembly 2 includes a pipe seat 21, on which a flexible conduit 22 is connected and sleeved outside the discharge pipe of the screw feeder 1. It also includes a clamp 23 for fixing the flexible conduit 22 to the discharge pipe. The flexible conduit 22 includes a straight pipe section 221, with a stacked section 222 formed on its upper part. An installation ring 223 is fixedly connected to the top of the stacked section 222 and bolted to the pipe seat 21. In the above scheme, the part used for guiding material is the straight pipe section 221, which has a smooth inner wall and is difficult to accumulate material. Although the stacked section 222 formed on its upper part has multiple sets of folds, it is also difficult to accumulate material because it does not directly contact the material, which facilitates subsequent cleaning. In addition, the length of the straight pipe section 221 can be changed by releasing the pipe body of the stacked section 222 or by further stacking the pipe body to meet different material discharge requirements. After the length of the straight pipe section 221 is adjusted, its length can be fixed by the clamp 23.

[0032] The working principle and usage process of this utility model:

[0033] The end of the guide tube assembly 2 is fixed by the support rod frame 35, which can change the degree of bending of the guide tube assembly 2 by sliding back and forth. At the same time, the height adjustment cylinder 34 can drive the support rod frame 35 to move up and down, thereby adjusting the setting height of the bottom end of the guide tube assembly 2. Finally, since the guide rod 32 can rotate freely, it can drive the support rod frame 35 to rotate, causing the end of the guide tube assembly 2 to shift. In summary, the end of the guide tube assembly 2 can be fixed within a height-adjustable circular range to meet different material dropping requirements. Moreover, no worker assistance is required to fix it after adjustment, making it extremely convenient to use.

[0034] The above-mentioned regulatory processes are specifically manifested as follows:

[0035] Since the rotating seat 321 is rotatably connected to the end seat 31, the rib 322 can rotate freely about the rotating seat 321. When the rib 322 rotates to the required angle and needs to be fixed, the clamping block 331 can be clamped by turning the adjusting screw 332 to restrict its rotation, thereby completing the fixation of the rotation angle of the rib 322.

[0036] The sleeve 341 can slide up and down along the rib 322. When it is necessary to fix the height of the sleeve 341, the friction plate 343 can be controlled by the locking screw 342 to make it fit tightly with the locking groove 323, and the sleeve 341 and the rib 322 are fixedly connected by the squeezing friction.

[0037] The support structure consisting of the ring frame 352 and the threaded rod 351 can fix and support the end of the conduit assembly 2. Since the threaded rod 351 is slidably connected to the guide tube 344, its support length can be changed. After the support length is adjusted, the position of the threaded rod 351 can be locked and fixed by the locking wheel 345 to prevent it from sliding again and changing the support length.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
