[0004] Although the curtains of the above-mentioned silo dustproof device can prevent dust diffusion to a certain extent, there are gaps between the curtains, resulting in poor dustproof effect. In addition, when loading materials, the curtains will also cause certain obstacles to the loading of the loader hopper. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a dust-proof device for a concrete storage silo, which has the advantages of effectively preventing dust from spreading, recovering dust, and avoiding obstruction to loader loading. It solves the problem that although the curtain of the existing silo dust-proof device can prevent dust from spreading to a certain extent, there are gaps between the curtains, resulting in poor dust-proof effect, and when loading, the curtains will also cause certain obstructions to the loading of the loader hopper.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a dust-proof device for a concrete storage silo, comprising a first bracket, four equidistantly arranged first silos are fixedly connected to the interior of the first bracket, a dust cover is fixedly connected to the upper surface of the first bracket, four equidistantly arranged pipes are fixedly connected to the interior of the dust cover, a guide fan is provided inside each of the pipes, a second bracket is provided on the back of the first bracket, four equidistantly arranged second silos are fixedly connected to the interior of the second bracket, a cover is provided on the upper surface of each of the second silos, one end of the pipe away from the dust cover is fixedly plugged into the interior of the cover, and a dust plate is slidably connected to the interior of the dust cover.

[0007] Through the above scheme, although the curtain of the existing silo dust-proof device can prevent dust from spreading to a certain extent, there are gaps between the curtains, and dust will still spread to the outside, resulting in poor dust-proof effect. In addition, when loading, the curtain will also cause certain obstacles to the loading of the loader's hopper. By setting a pipe between the first silo and the second silo and setting a guide fan inside the pipe, the dust generated during the loader's loading process can be diverted, effectively avoiding the diffusion of dust, and recovering the dust, optimizing the dust-proof effect of the device, and avoiding obstacles to the loader's loading.

Two gears are fixedly sleeved on the outer circumference of the output shaft, and racks are fixedly connected on both sides of the dust cover, and the racks are respectively engaged with the gears.

[0011] Through the above scheme, the output shaft drives the gear to rotate, and the gear drives the rack to rise and fall, thereby driving the dustproof plate to rise and fall and open and close.

[0012] Furthermore, a baffle is provided inside each of the pipes, and through holes arranged at equal intervals are opened inside the baffle.

[0013] Through the above solution, the baffle shields the guide fan, improving the safety of the guide fan operation. The through holes on the baffle can realize the circulation of gas, and then guide and recover the dust in the gas to prevent dust from spreading.

[0014] Furthermore, a clamping ring is fixedly sleeved on the outer circumferential surface of each baffle, and a clamping groove is opened inside each pipe, and the clamping ring is respectively clamped with the clamping groove.

[0015] Through the above solution, the baffle can be positioned by the clamping ring and the clamping groove, which makes it easy to install and disassemble the baffle.

[0016] Furthermore, a mounting plate is fixedly sleeved on the outer circumferential surface of each pipe, and the mounting plate is fixedly connected to the dust cover by bolts.

[0017] Through the above solution, the mounting plate is mounted on the dust cover by bolts, which facilitates installation and removal of the pipeline.

[0018] Furthermore, a support seat is fixedly connected to the upper surface of the dust cover, and the outer circumferential surface of the output shaft is rotatably connected to the interior of the support seat.

[0019] Through the above solution, the output shaft is supported and the stability of the output shaft movement is improved.

[0020] Furthermore, a limit ring is fixedly sleeved on the outer circumferential surface of the output shaft, and the outer circumferential surface of the limit ring is rotatably connected to the interior of the support seat.

[0021] Through the above solution, the output shaft is restricted to avoid sliding and offsetting of the output shaft, thereby increasing the stability of the output shaft movement.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] The dust-proof device for the concrete storage silo is configured with a pipe between the first silo and the second silo and a guide fan inside the pipe, so that the dust generated during the loader loading process can be guided away, thereby effectively preventing the dust from spreading and recovering the dust, optimizing the dust-proof effect of the device, and avoiding obstruction to the loader loading. This solves the problem that the curtain dust-proof effect of the existing silo dust-proof device is poor and the curtain will cause certain obstruction to the loader hopper loading during loading.

Two gears 12 are fixedly sleeved on the outer circumference of the output shaft 11. Racks 13 are fixedly connected to both sides of the dust plate 9. The racks 13 are respectively engaged with the gears 12. The output shaft 11 drives the gear 12 to rotate, and the gear 12 drives the rack 13 to rise and fall, thereby driving the dust plate 9 to rise and fall and open and close.

[0035] See also Figure 3 and Figure 4 A baffle 14 is provided inside each pipe 4, and equidistantly arranged through holes are opened inside the baffle 14. The baffle 14 blocks the guide fan 5 to improve the safety of the operation of the guide fan 5.

[0036] See also Figure 3 and Figure 4 The outer circumference of each baffle 14 is fixedly sleeved with a clamping ring 15, and the interior of each pipe 4 is provided with a clamping groove 16. The clamping ring 15 is respectively clamped with the clamping groove 16.

[0040] A dust-proof device for a concrete storage silo in this embodiment is provided. By setting a pipe 4 between a first silo 2 and a second silo 7 and providing a guide fan 5 inside the pipe 4, the dust generated during the loading process of the loader can be guided, thereby effectively preventing the dust from spreading and recovering the dust, optimizing the dust-proof effect of the device, and avoiding the effect of hindering the loading of the loader. This solves the problem that the curtain dust-proof effect of the existing silo dust-proof device is poor, and the curtain will cause certain obstacles to the loading of the loader hopper during loading.

[0041] It should be noted that the pipe 4 is composed of two parts, a hard pipe and a soft pipe. The end of the pipe 4 close to the dust cover 3 is a hard pipe, which is used to install the guide fan 5. The end of the pipe 4 close to the cover 8 is a soft pipe, which is convenient for connecting the cover 8 with the second silo 7, so that the position of the second bracket 6 can be flexibly adjusted in a small range.

[0042] The working principle of the above embodiment is:

[0043] The startable motor 10 is used as power to drive the gear 12 to rotate through the output shaft 11, and the gear 12 drives the dustproof plate 9 to lift and open and close through the rack 13. When the loading operation is not in progress, the dustproof plate 9 can be completely closed to perform dust prevention operations on the first silo 2. When the loading operation is required, the dustproof plate 9 is moved up and opened, and then the guide fan 5 is started. The dust generated when the loader loads the material will be sucked into the pipe 4 through the through hole on the baffle 14 under the action of the guide fan 5, avoiding the diffusion of dust during loading and causing dust pollution. The dust sucked into the pipe 4 will enter the corresponding second silo 7 through the pipe 4 for recycling and storage, and will be used later after accumulating to a certain amount to avoid waste.
