Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Please refer to Figures 1-10 The present application provides a technical solution: a concrete aggregate feeding mechanism, comprising at least four transmission supports 1, comprising,

[0033] The conveying assembly is arranged above the transmission support 1 for conveying the aggregate;

[0034] The roller brush assembly 6 is arranged between the transmission support 1 and the conveying assembly for cleaning the impurities adhered to the conveying assembly, wherein the roller brush assembly 6 comprises,

[0035] The roller brush mounting plate 61 is at least two, symmetrically connected below the conveying assembly, and the roller brush connecting rod 63 is rotatably connected between the two roller brush mounting plates 61, and the roller brush body 64 is connected to the roller brush connecting rod 63, and one side of one of the roller brush mounting plates 61 is connected with the roller brush drive motor 62 for driving the rotation of the roller brush body 64;

[0036] The collection box 7 is connected to the transmission support 1 and located below the roller brush body 64 for storing impurities.

[0037] In specific implementation, the conveying assembly is installed above the transmission bracket 1 and is responsible for conveying the sand and stones. The drum brush driving motor 62 is started to drive the drum brush body 64 to rotate. Then, the rotating drum brush body 64 contacts the surface of the conveying assembly. With the operation of the conveying assembly, the drum brush body 64 continuously brushes the surface of the conveying assembly to scrape off the impurities such as residual sand and stone particles and dust from the surface of the conveying assembly. This continuous cleaning action ensures the cleanliness of the surface of the conveying assembly and avoids the impurities from mixing into the sand and stones again or falling to the ground during the conveying process. The collection box 7 is connected to the transmission bracket 1 and is just below the drum brush body 64. The impurities scraped off from the surface of the conveying assembly by the drum brush body 64 directly fall into the collection box 7 under the action of gravity. The collection box 7 plays a role in centralized storage of the impurities and avoids the scattering of the impurities on the ground, which facilitates the subsequent unified treatment. In this way, the automatic cleaning and collection of the impurities during the conveying of the sand and stones are realized, and the manual frequent cleaning of the residual materials on the surface of the feeding mechanism is not needed, which improves the work efficiency and maintains the cleanliness of the production environment.

[0038] Referring to Figure 1 , the conveying assembly comprises two mounting plates connected to the top of the transmission bracket 1. The first transmission roller 3 and the second transmission roller 4 are symmetrically and rotatably connected between the two mounting plates. The conveying belt 2 is drivingly connected between the first transmission roller 3 and the second transmission roller 4.

[0039] In specific implementation, the mounting plates facilitate the installation of the first transmission roller 3 and the second transmission roller 4. The conveying belt 2 drivingly connected between the first transmission roller 3 and the second transmission roller 4 facilitates the conveying of the materials.

[0040] Referring to Figure 1 and Figure 10 , the two mounting plates are connected with a sensor assembly 109. The sensor assembly 109 is located at the feeding end of the conveying belt 2. The sensor assembly 109 comprises a sensor mounting plate 1090 and a sensor body 1091. The sensor mounting plate 1090 is installed on the mounting plate. The sensor body 1091 is installed on the sensor mounting plate 1090. The detection end of the sensor body 1091 corresponds to the conveying surface of the conveying belt 2 and is used for sensing whether there is sand and stone powder residue on the surface of the conveying belt 2.

[0041] It should be noted that the sensor body 1091 is electrically connected with the drum brush driving motor 62.

[0042] In specific implementation, when the feeding mechanism is started and the conveying belt 2 starts to run, the sensor body 1091 enters the working state. It uses its own sensing principle such as photoelectric sensing, infrared sensing, etc., depending on the sensor type, to monitor the conveying surface of the conveying belt 2 in real time. If there are sand, stones and slag on the conveying belt 2, these slag will change the signal received by the detection end of the sensor body 1091, and then the signal will be transmitted to the drum brush driving motor 62 to start the drum brush driving motor 62 to clean the sand and stones.

[0044] In specific implementation, the output shaft of the transmission driving motor body 502 is connected with the transmission driving driving wheel 504, the transmission driving motor body 502 drives the transmission driving driving wheel 504 to rotate synchronously, and the transmission driving driving wheel 504 and the transmission driving driven wheel 505 are transmissionally connected through the transmission driving synchronous belt 506. When the transmission driving driving wheel 504 rotates, the transmission driving driven wheel 505 rotates in turn.

[0045] Referring to Figure 6 , a third transmission driving roller 509 is coaxially arranged on one side of the transmission driving driven wheel 505, a second transmission driving roller 508 and a first transmission driving roller 507 are rotatably connected in the transmission driving shell 501, the first transmission driving roller 507, the second transmission driving roller 508 and the third transmission driving roller 509 are arranged in a mountain shape, and the conveying belt 2 is transmissionally connected on the first transmission driving roller 507, the second transmission driving roller 508 and the third transmission driving roller 509.

[0046] In specific implementation, since the third transmission driving roller 509 is coaxially arranged with the transmission driving driven wheel 505, the rotation of the transmission driving driven wheel 505 directly drives the third transmission driving roller 509 to rotate synchronously, and the first transmission driving roller 507, the second transmission driving roller 508 and the third transmission driving roller 509 are arranged in a mountain shape, which helps to form a stable support structure and provides a transmission path for the conveying belt 2 to rotate.

[0047] Referring to Figure 6 , the transmission driving shell 501 is connected with a transmission driving motor mounting plate 503, and the transmission driving motor body 502 is connected to the transmission driving motor mounting plate 503.

[0048] In particular implementation, the transmission driving motor mounting plate 503 is arranged to facilitate the installation of the transmission driving motor body 502.

[0049] Reference Figure 3 The drum brush bearing 65 is connected to the drum brush mounting plate 61, and one end of the drum brush connecting rod 63 is rotatably connected to the drum brush bearing 65.

[0050] In particular implementation, the drum brush bearing 65 is arranged to facilitate the rotation of the drum brush connecting rod 63.

[0051] Reference Figure 7 The transmission driving housing 501 comprises;

[0052] The first transmission driving side plate 5010 and the second transmission driving side plate 5011 are respectively connected to the two mounting plates, the transmission driving left side plate 5012 and the transmission driving right side plate 5013 are symmetrically connected between the first transmission driving side plate 5010 and the second transmission driving side plate 5011, the first transmission driving connecting rod 5014 and the second transmission driving connecting rod 5015 are rotatably connected between the first transmission driving side plate 5010 and the second transmission driving side plate 5011, and the first transmission driving roller 507 and the second transmission driving roller 508 are respectively connected to the first transmission driving connecting rod 5014 and the second transmission driving connecting rod 5015.

[0053] It should be noted that the first transmission driving side plate 5010 is connected to the transmission driving shell 510 on one side.

[0054] In particular implementation, the first transmission driving side plate 5010 and the second transmission driving side plate 5011 are respectively connected to the two mounting plates, which provides a connection basis for the entire transmission driving housing 501 and the external mounting plate, the transmission driving left side plate 5012 and the transmission driving right side plate 5013 are symmetrically connected between the first transmission driving side plate 5010 and the second transmission driving side plate 5011, which together with the front and rear side plates form a closed and stable space structure to provide support and protection for the internal transmission components.

[0055] Working principle: when the feeding mechanism is started and the conveyor belt 2 starts to run, the sensor body 1091 enters the working state. It uses its own sensing principle such as photoelectric sensing, infrared sensing, etc., which depends on the type of sensor, to monitor the conveying surface of the conveyor belt 2 in real time. If there are sand, stones and slag on the conveyor belt 2, these slag will change the signal received by the detection end of the sensor body 1091, and then the signal will be transmitted to the drum brush driving motor 62 to start the drum brush driving motor 62 to clean the sand and stones;

[0056] The conveying assembly is installed above the transmission bracket 1 and is responsible for conveying the sand and gravel. The drum brush body 64 is driven to rotate by starting the drum brush driving motor 62. Then the rotating drum brush body 64 contacts the surface of the conveying assembly. As the conveying assembly operates, the drum brush body 64 continuously brushes the surface of the conveying assembly to scrape off the impurities such as residual sand and gravel particles and dust from the surface of the conveying assembly. This continuous cleaning action ensures the cleanliness of the surface of the conveying assembly, avoiding the impurities from mixing into the sand and gravel again during the conveying process or falling to the ground. The collection box 7 is connected to the transmission bracket 1 and is just below the drum brush body 64. The impurities scraped off from the surface of the conveying assembly by the drum brush body 64 directly fall into the collection box 7 under the action of gravity. The collection box 7 plays a role in centralized storage of impurities, avoiding the scattering of impurities on the ground and facilitating subsequent unified treatment. In this way, the automatic cleaning and collection of impurities during the sand and gravel conveying process are realized, without the need for frequent manual cleaning of the residual materials on the surface of the feeding mechanism, improving the work efficiency and maintaining the cleanliness of the production environment.
