Description

Technical Field

[0001] The utility model relates to the technical field of sand and gravel conveying, in particular to a sand and gravel conveyor belt residual material recovery device. Background Art

[0002] During the sand and gravel conveying process, due to the concave structure of the conveyor belt and the presence of intermittent stripes on the surface of the conveyor belt to increase friction, a certain amount of sand and gravel residue often remains on the conveyor belt surface. If these residues are not cleaned up in a timely manner, it will not only waste resources but may also cause wear and tear on the conveyor belt and its surrounding equipment, affecting the normal operation and service life of the equipment. Currently, although there are some residual material cleaning devices on the market, most of them have poor cleaning effects. For example, CN210654884U relies on an external motor to drive the vibrator, which has problems such as high energy consumption, complex structure, and frequent maintenance.

[0003] Therefore, it is necessary to provide a new sand and gravel conveyor belt residual material recovery device to solve the above-mentioned technical problems. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] See also Figures 1 to 6 The embodiment of the present invention provides a device for recovering residual material from a sand and gravel conveyor belt. The device comprises a material removal seat 1, an arc-shaped scraper 2 and an exciting component 3.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 6 , a fixed truss 7 is fixedly installed on the removing seat 1, and an arc-shaped scraper 2 with an arc-shaped scraping blade is installed on the removing seat 1. Specifically, a knife groove 1a is opened on the removing seat 1, and the arc-shaped scraper 2 is inserted into the knife groove 1a and fixed by bolts;

[0028] Several groups of equally spaced excitation components 3 are installed on the material removal seat 1 on the rear side of the arc scraper 2. Several mounting holes 1b arranged side by side and equally spaced are provided on the material removal seat 1. Several groups of excitation components 3 are respectively installed in each mounting hole 1b, and the excitation component 3 includes a sliding column 31. The sliding column 31 is inserted into the mounting hole 1b opened in the material removal seat 1 and is slidably connected to the mounting hole 1b. The upper column head of the sliding column 31 is embedded with a rotatably connected steel ball 32, and the lower column head of the sliding column 31 is fixedly installed with a spring 33, and the spring 33 is fixedly connected to the inner bottom wall of the mounting hole 1b.

[0029] In actual use, the present application can be installed with two groups. One group is installed on the frame of the return belt below the unloading end of the sand and gravel conveyor belt using a fixed truss 7, so that the arc scraper 2 is facing the sand and gravel return conveyor belt (no need to install a collection container, the present application can directly scrape the remaining material on the sand and gravel conveyor belt directly onto the aggregate slope), and the other group is installed on the frame at the end of the return conveyor belt of the sand and gravel conveyor belt, with an aggregate container (such as the attached Figure 7 shown).

[0030] Among them, the arc scraper 2 can be made of carbide or polyurethane material, and its arc structure can be prepared (cut) according to the arc of the sand and gravel conveyor belt during installation, so that the arc scraper 2 matches the arc surface formed by the conveyor belt. When installing the arc scraper 2, keep the distance between the arc scraper 2 and the conveyor belt at 0.5-1.2cm (not in contact with the stripes).

[0031] It should be noted that: when the material removal seat 1 is installed, the sliding column 31 of each group of excitation components 3 drives the steel ball 32 to resist the conveyor belt at the corresponding angle under the action of the spring 33. At this time, when the sand and gravel conveyor belt is returning, the arc scraper 2 can scrape off the residual material attached to the return conveyor belt. At the same time, the steel ball 32 compresses the spring 33 after resisting the stripes distributed on the conveyor belt. Therefore, as the steel ball 32 slides alternately on the striped part and the non-striped part on the conveyor belt, the sliding column 31 cooperates with the spring 33 to continuously impact the conveyor belt and vibrate, thereby shaking off the residual material attached to the conveyor belt. This vibration effect not only enhances the scraping effect of the arc scraper 2, but also prevents the accumulation of residual material on the conveyor belt, ensuring the continuous and efficient operation of the sand and gravel conveyor belt (the residual material scraped or shaken off at the end of the return conveyor belt of the sand and gravel conveyor belt falls into the aggregate container for recovery).

[0032] Furthermore, a blanking cavity 1c is provided on the material removal seat 1 between the excitation component 3 and the arc scraper 2, so that the residual material scraped off by the arc scraper 2 can fall from the blanking cavity 1c, thereby preventing the residual material from accumulating on the material removal seat 1 between the excitation component 3 and the arc scraper 2.

[0033] The surface of the steel ball 32 is nitrided (hardness ≥ HRC60), thereby improving the wear resistance of the steel ball 32 .

[0034] In the embodiments of the present invention, please refer to Figures 1 to 6 , a guide plate 4 for guiding the residual material scraped off the sand and gravel conveyor belt is also installed on the material removal seat 1, a fixed frame 5 is fixedly installed on the material removal seat 1, and a rotating shaft frame 51 extending toward the tail side of the material removal seat 1 is fixedly installed on the fixed frame 5, the connecting end of the guide plate 4 is sleeved on the rotating shaft frame 51 and rotatably connected to the rotating shaft frame 51, and both side walls of the fixed frame 5 are installed with docking parts 6 for elastically connecting the guide plate 4;

[0035] The docking part 6 includes a sleeve 61, which is rotatably connected to the fixed frame 5 by rotating the A frame 611, and a sliding connecting rod 62 is inserted into the sleeve 61. The inserted end of the connecting rod 62 is fixedly installed with a tension spring 63, and the other end of the tension spring 63 is fixedly connected to the inner tube wall of the sleeve 61. The extended end of the connecting rod 62 is rotatably connected to the middle plate body of the side plate surface of the guide plate 4 by rotating the B frame 621.

[0036] It should be noted that: when the residual material falls, it slides down along the guide plate 4. Since the residual material falling each time is different, the connecting rod 62 is able to stretch the tension spring 63 when the guide plate 4 is subjected to the falling material, so that the guide plate 4 can deflect downward around the rotating shaft frame 51, effectively reducing the impact force when the residual material falls and is recovered. This design not only protects the present application and the surrounding environment, but also improves the stability and reliability of the present application. At the same time, the elastic effect of the docking member 6 also ensures that the guide plate 4 can quickly return to its original position when there is no residual material falling, and is ready for the next residual material to fall.

[0037] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
