Description

Technical Field

[0001] This utility model relates to the field of vibratory conveying equipment technology, and in particular to a boltless internal material scraper. Background Technology

[0002] Vibrating conveyor equipment is a type of mechanical equipment that uses vibration force to transport materials. It is widely used in industries such as mining, metallurgy, building materials, chemicals, and food processing.

[0003] In the operation of vibrating conveyor equipment, scrapers are an indispensable component. The main function of scrapers is to help maintain a stable flow of materials during the conveying process, prevent material accumulation or blockage, and ensure that materials are evenly distributed on the conveyor belt or in the trough. In addition, scrapers can also help clean up material residues adhering to the conveyor belt, reduce material wear on the conveyor belt, and improve the service life and working efficiency of the equipment.

[0004] The inventors have discovered at least the following problems in the prior art:

[0005] Traditional vibrating conveyor equipment is often designed with bolts to fix the scraper and achieve synchronous movement with the conveyor. However, this connection method poses significant safety hazards in specific scenarios such as food-grade material conveying. Since the bolts may loosen or fall off due to vibration, if the bolts fall into the material, they will not only contaminate the material but may also pose a threat to human health.

[0006] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0007] The purpose of this utility model is to provide a material scraper without internal bolts, so as to solve the problem that in the prior art, when the scraper is fastened with bolts, there is a risk of it falling off.

[0008] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0009] An internal boltless material scraper includes a scraper and a vibrating screen. A scraper shaft is fixedly connected to the top of the scraper. A fixed bushing and an adjusting handle assembly are respectively provided at both ends of the scraper shaft. The fixed bushing is fixedly connected to the inner wall of the vibrating screen, and the adjusting handle assembly is located on the outer side of the vibrating screen. The adjusting handle assembly includes a limiting plate, and handles and adjusting shafts on both sides of the limiting plate. The end of the adjusting shaft away from the limiting plate has a connecting shaft type, and the two ends of the scraper shaft have connecting holes that fit the connecting shaft type.

[0010] Preferably, a limiting rod is fixedly connected to the outer side of the vibrating screen near the adjusting handle assembly, the limiting plate has a limiting groove, and one end of the limiting rod fits into the inside of the limiting groove.

[0011] Preferably, the adjusting shaft passes through the vibrating screen, and a fixed pressure plate, a fixed seat, and a sealing gasket are provided around the adjusting shaft.

[0012] Preferably, the sealing gasket is fixedly connected to the periphery of the vibrating screen, and the fixing seat and the fixing pressure plate are sequentially fixedly connected to one side of the sealing gasket.

[0013] Preferably, the fixed pressure plate has a notch, and the inner sidewall of the notch has a stepped groove that fits the outer periphery of the adjusting shaft.

[0014] The beneficial effects of this utility model are:

[0015] I. This utility model, through the mutual cooperation of the adjustable handle assembly, fixed pressure plate, fixed seat, sealing gasket and scraper shaft, allows the connecting shaft to be directly inserted into the connecting hole, thereby driving the scraper shaft and scraper to rotate. This eliminates the need for fastening bolts inside the vibrating screen, effectively avoiding the risk of foreign objects falling in and ensuring the purity and safety of the materials.

[0016] Second, through the cooperation of the adjustable handle assembly, fixed pressure plate, fixed seat, sealing gasket and scraper shaft, this utility model makes the connection between the scraper and the vibrating screen tighter and more stable. During the operation of the equipment, even if subjected to external forces such as vibration, the scraper is not easy to loosen or fall off, thereby improving the overall stability of the equipment.

[0017] Third, this utility model, through the cooperation of the adjustable handle assembly, fixed pressure plate, fixed seat, sealing gasket and scraper shaft, reduces the need for frequent maintenance and replacement due to loose, worn or lost bolts by using a boltless connection method. This not only reduces maintenance costs, but also reduces equipment downtime and improves production efficiency.

[0018] Fourth, this utility model, through the cooperation of the adjustable handle assembly, fixed pressure plate, fixed seat, sealing gasket and scraper shaft, makes the boltless connection method easier to install and disassemble the scraper than the traditional bolt connection method. This makes it more convenient and faster to repair, clean or replace the scraper, and further reduces the complexity and difficulty of maintenance work. Attached Figure Description

[0032] This utility model provides a boltless material scraper, including a scraper 9 and a vibrating screen 7. A scraper shaft 5 is fixedly connected to the top of the scraper 9. A fixed bushing 6 and an adjusting handle assembly 1 are respectively provided at both ends of the scraper shaft 5. The fixed bushing 6 is fixedly connected to the inner wall of the vibrating screen 7, and the adjusting handle assembly 1 is located on the outer side of the vibrating screen 7.

[0033] The adjustment handle assembly 1 includes a limiting plate 12, and handles 11 and adjustment shaft 14 on both sides of the limiting plate 12. The end of the adjustment shaft 14 away from the limiting plate 12 is provided with a connecting shaft type 15, and the two ends of the scraper shaft 5 are provided with connecting hole type 51 that fits the connecting shaft type 15.

[0034] The vibrating screen 7 is part of the structure of the vibrating screen; the fixed bushing 6 is also equipped with an adjusting shaft 14 on the side near the scraper shaft 5, so as to fit with both ends of the scraper shaft 5; the scraper 9 is the scraper of the vibrating conveying equipment in the prior art.

[0035] In a further embodiment, a limiting rod 8 is fixedly connected to the outer side of the vibrating screen 7 near the adjusting handle assembly 1, and a limiting groove 13 is formed on the limiting plate 12, with one end of the limiting rod 8 fitting into the interior of the limiting groove 13.

[0036] In this embodiment, the limiting rod 8, together with the limiting slide groove 13, is used to limit the rotational range of the adjusting handle assembly 1 and the scraper shaft 5.

[0037] In a further embodiment, the adjusting shaft 14 passes through the vibrating screen 7, and a fixed pressure plate 2, a fixed seat 3 and a sealing gasket 4 are provided around the adjusting shaft 14.

[0038] In this embodiment, the cross-sections of the fixed base 3 and the sealing gasket 4 fit the periphery of the fixed pressure plate 2, and are connected to the periphery of the vibrating screen 7 by bolts.

[0039] In a further embodiment, the sealing gasket 4 is fixedly connected to the periphery of the vibrating screen 7, and the fixing seat 3 and the fixing pressure plate 2 are sequentially fixedly connected to one side of the sealing gasket 4.

[0040] In this embodiment, the sealing gasket 4 is used to ensure the sealing of the inside and outside of the vibrating screen 7.

[0041] In a further embodiment, the fixed pressure plate 2 has a notch 21, and the inner sidewall of the notch 21 has a stepped groove 22, which fits the periphery of the adjusting shaft 14.

[0043] The working principle of this utility model is as follows:

[0044] When food materials pass over the vibrating screen 7 and the tilt angle of the scraper 9 needs to be adjusted, the entire adjustment handle assembly 1 can be rotated by holding the handle 11. Through the connection of the connecting shaft type 15 and the connecting hole type 51, the scraper shaft 5 drives the scraper 9 to rotate. During the rotation, it will be restricted by the limit rod 8 and the limit slide groove 13, thus replacing the traditional method of connecting the scraper 9 with bolts. This effectively avoids the risk of foreign objects falling. When conveying food-grade materials, it can ensure the purity and safety of the materials. At the same time, since bolts are not used for fixing, this not only reduces maintenance costs, but also makes it less likely for the scraper to loosen or fall off even under the action of external forces such as vibration, thereby improving the overall stability of the equipment.
