Description

Technical Field

[0001] The utility model relates to the technical field of silo unloaders, in particular to a movable cone of a silo unloader. Background Art

[0002] The cantilever silo unloader is widely used in cylindrical storage. The material is concentrated to the middle part through the rotating cantilever for centralized discharging. The discharging stability is high, and the discharging speed can be controlled.

[0003] The existing cantilever silo unloader mainly includes a central slewing bearing. A cantilever is installed on the central slewing bearing. A discharging auger is installed inside the cantilever. The central slewing bearing is installed at the upper end of the discharging port. During the process that the central slewing bearing drives the cantilever to revolve, the discharging auger rotates. A cone is installed on the central slewing bearing. The cone has good anti-deformation ability and can disperse the pressure at the upper end of the central slewing bearing.

[0004] In the prior art, the cone is fixedly connected with the central slewing bearing, and the cone rotates with the central slewing bearing. When the stored materials are materials that are not easy to agglomerate, such as grains and wood chips, the friction between the cone and the materials is small, and the resistance to the rotation of the cone is small, and it can rotate normally. During the use process, it is found that when the stored materials are soybean meal, due to the agglomeration of soybean meal, the friction between the soybean meal and the cone is large, the rotation of the cone is blocked, and even the connecting bolts between the cone and the central slewing bearing are broken. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a movable cone of a silo unloader that enables the cone to rotate relative to the central slewing bearing.

[0006] The utility model is realized by the following technical solutions: A movable cone of a silo unloader includes a cone body connected to the central slewing bearing. A rotating connection device is arranged between the cone body and the central slewing bearing. The rotating connection device includes a connecting ring one arranged at the upper end of the central slewing bearing. A connecting ring two is arranged at the lower end of the cone body and is rotatably connected to the connecting ring one. The connecting ring one and the connecting ring two are hermetically connected.

[0007] Further, the connecting ring two is sleeved outside the connecting ring one, and the connecting ring one and the connecting ring two are hermetically connected through a sealing ring.

[0008] Further, a gap control device is arranged between the connecting ring two and the central slewing bearing.

[0009] Further, the gap control device includes a support ring arranged on the central slewing bearing, and an isolation layer is arranged at the upper end of the support ring.

[0010] Furthermore, the connecting ring II and the cone body are connected by bolts.

[0011] Furthermore, support ribs are arranged on the inner wall of the cone body.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. The cone body and the central slewing bearing are rotationally connected through the connecting ring I and the connecting ring II. When the resistance received by the cone body is small, the cone body can rotate with the central slewing bearing. When the resistance received by the cone body is large, relative rotation can occur between the cone body and the central slewing bearing, thereby avoiding damage and improving the use stability.

[0014] 2. The connecting ring II is sleeved outside the connecting ring I. The connecting ring I and the connecting ring II are hermetically connected through a sealing ring. A clearance control device is arranged between the connecting ring II and the central slewing bearing, which can ensure the positioning effect between the connecting ring I and the connecting ring II, isolate the connecting ring II from the connecting ring I and the central slewing bearing, reduce the friction force during relative rotation, and at the same time avoid the sparks generated by rigid friction.

[0019] In the description of the present utility model, it should also be noted that unless otherwise clearly specified 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 components. 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.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] As Figures 1-3 shown, a movable cone of a silo unloader includes a cone body 2 connected to a central slewing bearing 1. The cone body 2 is formed by welding steel plates. Support ribs are welded inside the cone body 2 to improve the anti-deformation strength of the cone body 2. A lifting lug is installed at the upper end of the cone body 2 to facilitate transportation and maintenance. A steel ring seat 5 is welded and fixedly installed at the lower end of the cone body 2, and the ring seat 5 can provide stable support for the cone body 2.

[0023] Generally, the cone body 2 and the central slewing bearing 1 are fixedly connected by bolts 9. When the stored materials in the warehouse are materials that are not easy to agglomerate, such as grains and wood chips, the friction between the cone and the materials is small, the resistance to the rotation of the cone is small, and it can rotate normally. During the use process, it is found that when the stored material in the warehouse is soybean meal, due to the agglomeration of soybean meal, the friction between the soybean meal and the cone is large, the rotation of the cone is blocked, and even the connecting bolts between the cone and the central slewing bearing 1 are broken. To reduce the friction between the cone body 2 and the materials, an attempt is made to lay a shielding layer above the cone body 2 to separate the materials from the cone body 2 to reduce the frictional resistance. Specifically, 2 cm - 3 cm of dry soybean meal particles are laid above the cone body 2, and a blocking ring is welded at the lower edge of the cone body 2 to block the dry soybean meal particles. The initial test effect is good, and the cone body 2 can rotate freely. After using for a period of time, the dry soybean meal particles are consumed, the resistance received by the cone body 2 increases, and finally the phenomenon that the connecting bolts between the cone body 2 and the central slewing bearing 1 are broken occurs.

[0024] Soybean meal is a widely used raw material, and the usage of soybean meal increases year by year. To solve the above problems, a technical solution is obtained in this embodiment. A rotating connection device is installed between the conical body 2 and the central slewing bearing 1. The rotating connection device includes a first connecting ring 7 fixed to the upper end of the central slewing bearing 1. A second connecting ring 6 is fixed to the lower end of the conical body 2 and is rotatably connected to the first connecting ring 7. The first connecting ring 7 and the second connecting ring 6 are hermetically connected. Specifically, a top plate 11 is installed at the upper end of the central slewing bearing 1. The first connecting ring 7 is connected to the top plate 11 by bolts 9, and the second connecting ring 6 is connected to the conical body 2 by bolts 9, which facilitates prefabrication. Since the outer diameters of both the first connecting ring 7 and the second connecting ring 6 are relatively large, during the manufacturing process, they are bent and formed in 3 - 4 segments and then welded together, which can reduce the manufacturing cost. The second connecting ring 6 is sleeved on the outside of the first connecting ring 7, and the first connecting ring 7 and the second connecting ring 6 are hermetically connected by a sealing ring 8. In this embodiment, the sealing ring 8 is an O-ring. Positioning grooves that match the sealing ring 8 are machined on both the first connecting ring 7 and the second connecting ring 6 to position the sealing ring 8. The first connecting ring 7 and the second connecting ring 6 are coaxially positioned by the sealing ring 8. The distance between the first connecting ring 7 and the second connecting ring 6 is 8 mm - 12 mm. The sealing ring 8 is extruded under normal conditions, generating frictional force with the first connecting ring 7 and the second connecting ring 6. Thus, under the condition of relatively small resistance, the conical body 2 and the central slewing bearing 1 can rotate synchronously, reducing the wear of the sealing ring 8. Under the condition of relatively large resistance, the conical body 2 and the central slewing bearing 1 rotate relative to each other.

[0025] Guide openings 10 that match the sealing ring 8 are machined at the upper end of the outside of the first connecting ring 7 and the lower end of the inside of the second connecting ring 6.

[0026] A gap control device is installed between the second connecting ring 6 and the central slewing bearing 1. Specifically, the gap control device includes a support ring 4 welded and fixed to the central slewing bearing 1. An isolation layer 12 is laid on the upper end of the support ring 4. The support ring 4 is a steel ring, and the isolation layer 12 is a vulcanized rubber layer. The thickness of the isolation layer 12 is 4 mm - 6 mm. The support ring 4 positions the isolation layer 12 and simultaneously controls the distance between the second connecting ring 6 and the central slewing bearing 1. The second connecting ring 6 is supported by the isolation layer 12. The second connecting ring 6 bears the gravity of the conical body 2 and the second connecting ring 6 itself. The vulcanized rubber material is selected, which has a relatively high hardness and a small deformation amount, thus avoiding the inclination of the conical body 2. The gap control device can control the distance between the first connecting ring 7 and the conical body 2, thus avoiding rigid friction when the conical body 2 and the central slewing bearing 1 rotate relative to each other. Both the sealing ring 8 and the isolation layer 12 are consumables and need to be replaced regularly.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
