Description

TECHNICAL FIELD

[0001] The utility model relates to adding mechanism technical field, more specifically, it relates to a casting sand adding mechanism. BACKGROUND

[0002] In the prior art, the current casting sand adding mechanism cannot effectively remove dust from the material during operation, and the casting sand usually contains a large amount of fine dust particles. These dusts not only pollute the environment during transportation and addition, but also affect the quality of the casting and the stability of the casting process. The presence of fine dust may cause uneven casting sand during molding, resulting in defects such as pores and cracks, affecting the strength and surface quality of the casting.

[0003] In the existing casting sand adding mechanism, there is often no special component for scraping the conveyor belt or material conveying channel. The conveyor belt is a key part of the casting sand during transportation, which needs to efficiently and stably convey the material from one place to another. However, the sand material often accumulates, clumps or adheres on the conveyor belt, which affects the flowability and conveying efficiency of the material, leading to uneven distribution of the material. Especially for wet sand or casting sand containing a large amount of sticky material, if there is no effective scraping device to remove the accumulated material, it may cause material blockage and equipment failure.

[0004] The existing casting sand adding mechanism often has the problem of poor conveying during material conveying, which may be caused by unreasonable design of the conveyor belt, unstable conveying speed or poor flowability of the material. During the conveying process, the flowability and uniformity of the casting sand are crucial for the quality of the casting. However, due to the friction and accumulation of the conveyor belt, the material may be stuck or unable to be smoothly transferred to the designated position. SUMMARY

[0016] (Three) beneficial effect

[0017] Compared with the prior art, the present invention provides a foundry sand adding mechanism, which has the following beneficial effects:

[0018] 1. The design of the exhaust pipe and exhaust fan in the material conveying assembly effectively solves the dust problem generated during the conveying of foundry sand. Through the operation of the exhaust fan, fine dust particles in the material can be sucked out in real time, avoiding dust pollution of the environment and also helping to improve casting quality. It also prevents excessive dust from affecting the molding effect of castings. The layout of the feed hopper, feed channel and discharge channel ensures the smooth flow of materials.

[0019] 2. The scraping assembly drives the scraper to move via an electric actuator, effectively removing adhering materials from the conveyor belt. This prevents sand from accumulating or clogging during transport due to moisture or stickiness. The scraper is in close contact with the conveyor belt, continuously scraping away residual sand from the material surface during operation, keeping the conveyor belt clean and preventing excessive material adhesion from affecting subsequent processes. Through this effective scraping mechanism, friction and wear on the conveyor belt caused by material adhesion are reduced, extending the conveyor belt's service life and lowering equipment maintenance frequency and costs.

[0020] 3. The conveyor assembly, through the cooperation of the conveyor belt and guide wheels, ensures stable material transport. The tight fit between the guide wheels and the conveyor belt ensures that the material is transported along the predetermined trajectory without deviation or scattering, enhancing the stability of the entire material conveying system. The design of the inclined bucket and filter screen ensures that the material can be smoothly discharged from the discharge pipe and effectively filters out unqualified particles and impurities. This design not only guarantees the quality of the material but also provides more suitable material for the subsequent casting process. Attached Figure Description

[0031] One end of the discharge channel 2 is connected with a discharge pipe 10, and a motor 11 is installed on the discharge channel 2.

[0032] The output end of the motor 11 is connected with a rotating rod 12.

[0033] The rotating rod 12 is installed with a spiral blade 13.

[0034] The output end of the electric push rod 9 is connected with a scraper 14.

[0035] In the embodiment, in use, the material is injected into the feeding channel 3 along the feeding hopper 4, and in the process of injecting the material, the dust in the material is sucked out by starting the exhaust fan 6 on the exhaust duct 5, and with the continuous injection of the material, the material enters the discharging channel 2, and at this time, the motor 11 is started to drive the rotating rod 12 at the output end to rotate, and in the rotating process, the spiral blade 13 on the rotating rod 12 continuously discharges the material, and with the continuous discharge, the material is discharged from the discharge pipe 10 to the filter screen 17, and then falls into the inclined hopper 18 on the conveying vehicle 16, and then falls into the conveying belt 20, and the conveying belt 20 is started to convey the material, and in use, the guide wheel 21 guides the conveying of the material, and then the material falls into the collection box 7, so that the discharging and conveying of the material is completed.

[0036] Please refer to Figures 4-5 As a casting sand adding mechanism embodiment of the conveying assembly, one side of the fixed table 1 is provided with the conveying assembly, and the conveying assembly comprises a connecting frame 15, a conveying vehicle 16 and a filter screen 17. The connecting frame 15 is arranged on one side of the fixed table 1, the conveying vehicle 16 is arranged on the connecting frame 15, and the filter screen 17 is installed on the conveying vehicle 16.

[0037] The conveying vehicle 16 is internally provided with an inclined hopper 18, and the conveying vehicle 16 is internally provided with a conveying table 19.

[0039] More specifically, in the conveying process of the material, part of the material may adhere to the conveying belt 20, and at this time, the material needs to be scraped off.
