Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to an automatic metering and batching device for commercial concrete. Background Art

[0002] After the commercial concrete is mixed, the manufacturer needs to transport the mixed fluid concrete to a suitable temporary storage location.

[0003] The patent document with publication number CN210544948U and patent name "An automatic metering and batching device with the function of conveying mixed materials" discloses an automatic metering and batching device, which realizes automatic metering and batching through the cooperation of a weighing bucket, a solenoid valve, a gravity sensor and a spiral conveying discharge, and the conveying process is completed by a conveyor belt.

[0004] In the actual working process of the above patent document, when fluid concrete of different grades is transported through a conveyor belt, there will generally be a period of time, because the mixing and production of concrete of different grades requires a certain amount of time. Therefore, during this period of time, concrete will remain on the conveyor belt and even cause a certain degree of hardening and solidification, which is not conducive to the smooth transportation operation of the conveyor belt over a long period of time. Utility Model Content

[0005] The utility model aims to address the deficiencies of the prior art and propose an automatic metering and batching device for commercial concrete, so as to solve the technical problem mentioned in the background technology that some existing automatic metering and batching devices for concrete do not clean up the residual concrete on the conveyor belt in time when transporting through the conveyor belt, thereby causing the residue on the conveyor belt to solidify and making it inconvenient for the later conveying operation of the conveyor belt.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The automatic metering and batching device for commercial concrete includes an automatic metering and batching component and a conveyor belt arranged below the automatic metering and batching component and used for cooperating with the batching and conveying of the components. The device also includes two pairs of vertical plates, a first rotating shaft is rotatably inserted between the two vertical plates of each pair, a sleeve is fixedly sleeved on the first rotating shaft, the conveyor belt is wound around the two sleeves from the opposite outer sides of the two sleeves, a mounting frame is provided outside the conveyor belt and on one side thereof, a scraping brush component is provided between the mounting frame and one of the first rotating shafts, the scraping brush component can slide vertically and abut against the belt section of the conveyor belt close to the first rotating shaft so as to scrape the conveyor belt, and the scraping brush component is used to hit the conveyor belt at intervals as the first rotating shaft rotates.

[0008] Working principle:

[0009] The operator places the mixed and stirred fluid concrete into the automatic metering and batching component. According to the transportation needs, the automatic metering and batching component can automatically transport a certain amount of fluid concrete to the conveyor belt, and then transport the fluid concrete to a predetermined location through the conveyor belt.

[0010] After using for a period of time, the operator can clean the remaining concrete on the conveyor belt according to the situation. Specifically, the operator starts the scraper assembly, and the scraper assembly can abut against the belt section of the conveyor belt close to the first rotating shaft after sliding vertically. When the conveyor belt is in the process of rotating and conveying, it is used to scrape the conveyor belt, and the scraper assembly is used to hit the conveyor belt at intervals as the first rotating shaft rotates. By hitting the conveyor belt, the fluid concrete that has initially set on the conveyor belt can be knocked open, and then with the scraping of the conveyor belt, the residue on the conveyor belt can be cleaned up in time and thoroughly.

[0011] The beneficial effects of the utility model are:

[0012] During the use of the utility model, when the conveyor belt needs to be cleaned, a scraping brush assembly is provided. During the rotation of the conveyor belt, the scraping brush assembly can slide vertically and abut against a belt section of the conveyor belt close to one of the first rotating shafts to scrape the conveyor belt.

[0013] On the other hand, the scraping brush assembly can hit the conveyor belt, which can break up the fluid concrete that has initially set on the conveyor belt. Combined with the scraping brush on the conveyor belt, the residues on the conveyor belt can be cleaned off in a timely and thorough manner. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 and Figure 2 As shown, the automatic metering and batching device for commercial concrete includes an automatic metering and batching component and a conveyor belt 1 arranged thereunder and used for cooperating with the batching and conveying thereof, and also includes two pairs of vertical plates 2, a first rotating shaft 3 is rotatably penetrated between the two vertical plates 2 of each pair, a sleeve 4 is fixedly sleeved on the first rotating shaft 3, the conveyor belt 1 is wound around the two sleeves 4 from the opposite outer sides of the two sleeves 4, a mounting frame 5 is provided outside the conveyor belt 1 and on one side thereof, a scraping brush component is provided between the mounting frame 5 and one of the first rotating shafts 3, the scraping brush component can slide vertically and abut against the belt section of the conveyor belt 1 close to the first rotating shaft 3, so as to scrape and brush the conveyor belt 1, and the scraping brush component is used to hit the conveyor belt 1 at intervals as the first rotating shaft 3 rotates.

[0020] By setting up a scraper brush assembly, the scraper brush assembly can slide vertically. On the one hand, it abuts against the belt section of the conveyor belt 1 close to one of the first rotating shafts 3 to scrape the conveyor belt 1 during the rotation of the conveyor belt 1. On the other hand, it can hit the conveyor belt 1 at intervals to break up the fluid concrete that has initially set on the conveyor belt 1. The two aspects are carried out simultaneously, and the residual concrete on the conveyor belt 1 can be cleaned more thoroughly.

[0021] like Figure 1 and Figure 2 As shown, the scraper assembly includes a cylinder 6 fixed on the mounting frame 5 and with the telescopic end pointing vertically downward, a scraper plate, a striking plate 7 rotatably arranged on the scraper plate, a first spring 8 and a striking rod 9 fixed on one of the first rotating shafts 3, one end of the first spring 8 is connected to the striking plate 7, and the other end thereof is connected to the scraper plate, and the first spring 8 is used to pull the striking plate 7 so that the striking plate 7 abuts against the conveyor belt 1. Specifically, a connecting plate 28 is fixed on the scraper plate, and a rotating rod 29 is rotatably penetrated on the connecting plate 28. The striking plate 7 is fixedly connected to the rotating rod 29, and the striking plate 7 is rotatably mounted on the scraper plate in this way. The striking rod 9 is used to push the striking plate 7 from the bottom of the striking plate 7 at intervals as the first rotating shaft 3 rotates, so that the striking plate 7 strikes the conveyor belt 1 at intervals.

[0022] When it is necessary to clean the conveyor belt 1, the operator starts the cylinder 6, and the cylinder 6 drives the scraper plate to move downward and abut against the conveyor belt 1. The conveyor belt 1 rotates relative to the scraper plate, and the scraper plate can scrape off the concrete on the conveyor belt 1. At the same time, the first rotating shaft 3 drives the striking rod 9 to rotate, and the rotating striking rod 9 can push and strike the striking plate 7 at intervals, so that the striking plate 7 leaves the conveyor belt 1 at intervals and strikes the conveyor belt 1 under the pulling action of the first spring 8. Through striking and scraping, the concrete on the conveyor belt 1 can be thoroughly cleaned.

[0023] like Figure 1 and Figure 2 As shown, the scraper plate includes a vertical tube 10 fixed at the telescopic end of the cylinder 6 and a scraper plate 11 vertically slidably inserted into the vertical tube 10. The scraper plate 11 abuts against the belt section of the conveyor belt 1 close to the first rotating shaft 3 connected to the striking rod 9. A vertical second spring 12 is provided in the vertical tube 10. The second spring 12 is connected to the scraper plate 11. The second spring 12 is used to continuously push the scraper plate 11 so that the scraper plate 11 continuously abuts against the conveyor belt 1. When relatively firm concrete remains and is bonded to the conveyor belt 1, the scraper plate 11 can be retracted into the vertical tube 10 under the action of the second spring 12 after abutting against this relatively firm concrete, thereby protecting the scraper plate 11 and preventing brute force from scraping the conveyor belt 1, thereby protecting the conveyor belt 1.

[0024] like Figure 1 and Figure 3 As shown, the striking end of the striking rod 9 is provided with an elastic block 13 made of rubber material, and the striking plate 7 is struck by the elastic block 13, so that the noise during operation can be reduced. The striking end of the striking rod 9 is provided with a threaded hole 14, and a screw 15 is fixed on the elastic block 13, and the screw 15 is threadedly connected in the threaded hole 14. The operator installs the elastic block 13 on the striking rod 9 through the cooperation of the threaded hole 14 and the screw 15. On the one hand, this method is convenient for disassembly and assembly, and on the other hand, multiple strikes will cause certain wear to the elastic block 13, making the elastic block 13 smaller. At this time, in order to ensure the top thrust of the elastic block 13 on the striking plate 7, the overall length of the elastic block 13 and the striking rod 9 can be adjusted by rotating the screw 15, so that the overall length does not shorten, and the top thrust can be ensured. The side of the elastic block 13 away from the striking rod 9 is a hemispherical spherical surface structure. This structural form can further reduce the friction between the elastic block 13 and the striking plate 7, thereby increasing the service life of the elastic block 13.

[0025] like Figure 1As shown, the automatic metering and batching assembly includes a vertical cylinder 16 with openings at the top and bottom, a first motor 17 fixed on a mounting frame 5, a second rotating shaft 18 arranged vertically downward at the output end of the first motor 17, a spiral sheet 19 arranged on the second rotating shaft 18, a support plate 20 and a metering bucket 21 fixed on the mounting frame 5, the second rotating shaft 18 is located in the vertical cylinder 16, a first electromagnetic valve 22 is arranged at the bottom opening of the vertical cylinder 16, two gravity sensors 23 are arranged on the support plate 20, and the metering bucket 21 is arranged on the gravity sensor 23, the top opening of the metering bucket 21 is opposite to the first electromagnetic valve 22, and the bottom opening of the metering bucket 21 is opposite to the first electromagnetic valve 22. A second solenoid valve 24 is provided, and a material drop hole 25 corresponding to the second solenoid valve 24 is opened on the support plate 20. Referring to the records in the background technology document, through the measurement of the gravity sensor 23 and through PLC control, it is possible to coordinately issue execution commands to the first motor 17, the first solenoid valve 22, and the second solenoid valve 24, so that they can automatically measure and transport ingredients. This part refers to the background technology document and belongs to the prior art, and will not be explained and described in detail here. The two gravity sensors 23 cooperate to monitor the amount of material in the measuring bucket 21, which is also a metering method well known to people in this field.

[0026] like Figure 1 As shown, the top of the vertical cylinder 16 is a trumpet-shaped expansion structure that expands outward in the circumferential direction. With this design, the operator can better convey the concrete into the vertical cylinder 16, and through the rotation cooperation of the first motor 17, the second rotating shaft 18 and the spiral blade 19, the concrete can be forcibly introduced into the measuring bucket 21. Figure 1 As shown, it also includes a second motor 26 and a belt 27. The second motor 26 is arranged on one side of the mounting frame 5. One end of the belt 27 is arranged at the output end of the second motor 26, and the other end is wound around one of the first rotating shafts 3 through a belt groove. Through the cooperation of the second motor 26 and the belt 27, the conveyor belt 1 can be automatically driven to rotate, so that the concrete can be transported more evenly.

[0027] Working principle:

[0028] The operator places the mixed and stirred fluid concrete into the automatic metering and batching component. According to the transportation needs, the automatic metering and batching component can automatically transport a certain amount of fluid concrete to the conveyor belt 1, and then transport the fluid concrete to a predetermined location through the conveyor belt 1.

[0029] After using for a period of time, the operator can clean the remaining concrete on the conveyor belt 1 according to the situation. The operator starts the scraper assembly, and the scraper assembly can abut against the belt section of the conveyor belt 1 close to the first rotating shaft 3 after vertical sliding. When the conveyor belt 1 is in the process of rotating and conveying, it is used to scrape the conveyor belt 1, and the scraper assembly is used to hit the conveyor belt 1 at intervals as the first rotating shaft 3 rotates. By hitting the conveyor belt 1, the fluid concrete that has initially set on the conveyor belt 1 can be knocked open, and then with the scraping of the conveyor belt 1, the residue on the conveyor belt 1 can be cleaned up in time and thoroughly.

[0030] Specifically, the telescopic end of the cylinder 6 moves the scraper plate downward and abuts against the conveyor belt 1, specifically, the scraper plate 11 abuts against the conveyor belt 1, and at this time the striking plate 7 also abuts against the conveyor belt 1. When the second motor 26 drives the first rotating shaft 3 to rotate through the belt 27, the conveyor belt 1 starts to rotate. At this time, the scraper plate 11 can scrape the conveyor belt 1. At the same time, the rotation of the first rotating shaft 3 drives the striking rod 9 to rotate. The elastic block 13 at the end of the striking rod 9 can intermittently hit the striking plate 7, so that the striking plate 7 hits the conveyor belt 1 at intervals, thereby completing the cleaning process of the conveyor belt 1.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
