Description

Technical Field

[0001] The utility model relates to the technical field of bin cleaners, in particular to a bin cleaner rotary rack for preventing material blockage. Background Art

[0002] Bin cleaners are widely used as discharging equipment for cylindrical storage bins and are installed at the bottom of the storage bins. At present, most of the bulk grain terminals or silos in China have flat-bottom structures. However, because their bin bottoms are all flat surfaces, a considerable part of the grain cannot flow out automatically when discharging from the bin. If manual cleaning is used for the bin bottom, the efficiency is very low, and the dust concentration in the silo is very high during the cleaning process, which seriously harms the health of workers. In addition, if a dust explosion occurs, the lives of the bin cleaning personnel will be endangered. Bin cleaners are special equipment dedicated to flat-bottom shallow cylindrical bins, steel silos and other bulk grain storage bins to clean the residual materials at the bottom of the bin, improving the bin cleaning efficiency and avoiding the risk hazards of manual operations.

[0003] Due to the large material pressure at the bottom of the storage, caking will occur, increasing the resistance of the rotary rack and reducing the stability of bin cleaning. To solve this technical problem, those skilled in the art install crushing teeth on the spiral blades of the auger. The crushing teeth are usually triangular and are connected to the spiral blades through anti-loosening bolts. Since the crushing teeth are in a high-load working state for a long time, deformation occurs, and then fracture and loosening occur, affecting subsequent use. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a bin cleaner rotary rack for preventing material blockage that can prevent the crushing teeth from loosening and ensure the stability of the storage bin.

[0006] Further, the connecting portion is in a sheet shape, the crushing teeth are triangular, the connecting portion and the crushing teeth are integrally formed, the connecting portion and the spiral blades are connected through anti-loosening bolts, and the anti-loosening device includes welding points arranged at the edges of the connecting portion and the spiral blades.

[0007] Further, the cross-section of the connecting portion is U-shaped, the connecting portion is clamped on the outer edge of the spiral blade, the two wings of the connecting portion and the spiral blades are connected through anti-loosening bolts, the crushing teeth are in a conical shape, and the anti-loosening device includes welding joints arranged on the bottom plate of the connecting portion, and the welding joints and the bottom of the crushing teeth are connected by welding.

[0008] Furthermore, the crushing teeth are fan-shaped, the connecting part and the crushing teeth are integrally formed, and the anti-loosening device includes a welding layer arranged between the top of the connecting part and the edge of the spiral blade.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In the description of the present utility model, it should also be noted that, unless otherwise clearly defined and limited, the terms "arranged", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1

[0020] As Figures 1-3 shown, a rotary frame of a bin cleaner for preventing material blockage includes a rotary frame body. The rotary frame body is connected to a central rotary seat 1. The rotary frame body includes a connecting frame 2. A discharge auger 4 is installed on the connecting frame. The connecting frame is connected to a revolution drive frame 3. A revolution drive trolley is installed on the revolution drive frame, thereby driving the rotary frame body to revolve around the central rotary seat. Since the auger is relatively long, the auger is made of multiple short augers. Adjacent two short augers are connected by a transmission shaft. A suspension shaft 5 is installed on the connecting frame. The transmission shaft is connected to the suspension shaft through a bearing seat, thereby realizing stable transmission and providing multi-point support for the auger, improving the support stability.

[0021] Crushing teeth 6 are installed on the spiral blade 401 of the auger. The crushing teeth are connected to the spiral blade through a connecting piece. The connecting piece includes a connecting portion 7 connected to the spiral blade. There is an anti-loosening device between the connecting portion and the spiral blade. In this embodiment, the connecting portion is in a sheet shape, the crushing teeth are in a triangular shape, the connecting portion and the crushing teeth are integrally formed, and are cut from a steel plate with a thickness of 16 - 20 mm, and are formed by drilling and grinding. The structure is simple and easy to manufacture. The connecting portion and the spiral blade are connected by anti-loosening bolts. The height value of the crushing teeth exceeding the spiral blade is 50 - 60 mm, and it has a good crushing effect. The anti-loosening device includes welding points 8 processed on the edge of the connecting portion and the spiral blade. Since the crushing teeth are relatively thick, the anti-deformation ability is relatively strong. When subjected to resistance, the acting force is concentrated on the anti-loosening bolts and the torque is relatively large. Under alternating stress, loosening is likely to occur. Welding points are processed at the edge of the connecting portion and the spiral blade, thereby reducing the torque. Since the crushing teeth are relatively thick, the welding points will not affect the structural strength. During maintenance, observing the state of the welding points can determine the damage state. When cracks are found, tighten the anti-loosening bolts and perform repair welding at the same time. The rotary frame of the bin cleaner for preventing material blockage provided in this embodiment is suitable for the storage of large granular materials such as corn and is not easy to agglomerate.

[0022] Embodiment 2

[0023] As Figure 4As shown in the figure, a rotary frame of a bin cleaning machine for preventing material blockage. Different from Embodiment 1, the cross-section of the connecting part 7 is U-shaped and is obtained by cutting a channel steel. The connecting part is clamped on the outer edge of the spiral blade 401 by an interference fit. The bottom plate of the connecting part abuts against the outer surface of the spiral blade for preliminary positioning. The two wings of the connecting part are connected to the spiral blade by anti-loosening bolts, so as to fix the connecting part and the spiral blade. The wall thickness of the connecting part is 10-12 mm. The crushing teeth 6 are conical in shape and have a height of 35-40 mm. The anti-loosening device includes a welding joint processed on the bottom plate of the connecting part. The welding joint is welded to the bottom of the crushing tooth. The conical tooth can be a hollow body or a solid body, and the structural strength can be guaranteed. An internal weld seam 10 is formed between the welding joint and the bottom of the crushing tooth, and an external weld seam 9 is formed between the outer edge of the bottom of the crushing tooth and the connecting body. Through two layers of welding, the connection strength is guaranteed and pre-assembly can be carried out. Since the connecting part forms a large connection area, the influence of welding on the structural strength is reduced. The rotary frame of the bin cleaning machine for preventing material blockage provided by this embodiment is suitable for the storage of materials such as soybean meal and wood chips that are prone to caking. In addition, it should be noted that the crushing teeth bear a large load and are prone to falling off. Since the connection between the connecting part and the screw auger is firm, the falling off is the falling off of the crushing teeth themselves, which is convenient to detect during outloading, and there will be no small pieces of iron falling off, thus ensuring the safety of the outloading equipment.

[0024] Embodiment 3

[0025] As Figures 5-6 shown in the figure, a rotary frame of a bin cleaning machine for preventing material blockage. The crushing teeth are fan-shaped, and the connecting part 7 and the crushing teeth 6 are integrally formed, with a thickness of 6-10 mm. The distance between adjacent two crushing teeth is 10-30 mm. The length of the crushing teeth is 300-400 mm. The height value of the crushing teeth exceeding the spiral blade is 15-20 mm. The anti-loosening device includes a welding layer 12 processed between the top of the connecting part and the edge of the spiral blade. The welding layer can be spot welding or full welding. Since the crushing teeth are relatively long and prone to deformation, multi-point support is carried out through the welding layer. The rotary frame of the bin cleaning machine for preventing material blockage provided by this embodiment is suitable for the storage of small-particle materials such as rice and wheat, and will not form large lumps. The crushing teeth mainly play a role in cutting.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
