Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, in particular to a silo bridge breaking device. Background Art

[0002] The garbage silo with a screw conveyor is an important part of the restaurant or kitchen waste pretreatment system. Traditional garbage silos are relatively small. During the operation of the production line, the restaurant or kitchen waste trucks need to queue up to unload, causing secondary pollution and traffic congestion on the factory roads. In order to solve this problem, the garbage silo has been improved and the silo volume has been increased. However, since there are many fibrous, rod-shaped or flaky garbage in the restaurant or kitchen waste, they cannot fall freely when they accumulate to a certain height in the silo, and a bridge phenomenon occurs above the screw conveyor. As a result, the garbage treatment system cannot operate normally and needs to be handled by operators. Utility Model Content

Those skilled in the art will easily recognize from the following description that, without departing from the principles described in the present utility model, alternative embodiments of the structures and methods shown in the present utility model can be adopted.

[0023] A silo bridge breaking device according to an embodiment of the utility model comprises:

[0024] A lifting rod is arranged inside the silo 14, and the lifting rod comprises a lifting rod free end 7 and a lifting rod fixed end 6;

[0025] The lifting rod fixed end 6 is rotatably connected to the top plate 1 of the silo 14 via a support 10;

[0026] The free end 7 of the lifting rod is connected to the winch 3 provided outside the silo 14 through the steel wire rope 4, so that the lifting rod is suspended above the screw conveyor 12, one end of the steel wire rope 4 is detachably connected to the free end 7 of the lifting rod through a buckle, and the other end of the steel wire rope 4 is fixedly connected to the winch 3;

[0027] The lifting rod is raised under the action of the winch 3 to break the bridge of the garbage in the silo 14.

[0028] For example, Figure 1 As shown, the silo bridge breaking device described in the utility model is matched with the screw conveyor 12, and each screw conveyor 12 is matched with one or two of the silo bridge breaking devices. When the length of the screw conveyor 12 used is relatively long, two silo bridge breaking devices can be matched, and when the length of the screw conveyor 12 used is relatively short, one silo bridge breaking device can be matched. In this embodiment, a relatively long screw conveyor 12 is used, and two silo bridge breaking devices are matched, which are respectively arranged on the left and right sides of the length direction of the screw conveyor 12, and the silo bridge breaking device located on the right side is taken as an example to illustrate its structure and connection relationship.

[0029] A hinge 9 is fixedly connected to the fixed end 6 of the lifting rod, and a support 10 is provided at a corresponding position on the inner side of the top plate 1. The hinge 9 is rotatably connected to the support 10, so that the lifting rod can rotate up and down around the hinge 9. The winch 3 is arranged on the outer side of the silo 14 and is fixed to the outer surface of the top plate 1 through a bracket. One end of the wire rope 4 passes through the pulley and extends into the interior of the silo 14 and is connected to the free end 7 of the lifting rod through a buckle, and the other end of the wire rope 4 is fixedly connected to the winch 3. When the silo 14 needs to be bridge-broken, the winch 3 is turned on, the wire rope 4 is wound around the winch 3, and the free end 7 of the lifting rod is gradually raised under the action of the wire rope. The lifting rod rotates and rises around the fixed end 6 of the lifting rod and lifts the accumulated kitchen waste upward, breaks up the bridged garbage and makes it scatter again to the effective working area of ​​the screw conveyor 12, and finally transports the kitchen waste to the subsequent processing equipment for further processing. It should be noted that the radial dimension of the lifting rod is significantly different from the radial dimension of the screw conveyor 12 . When the kitchen waste falls into the silo 14 , the lifting rod will not have a substantial impact on the falling process.

[0030] In an optional embodiment, a positioning block 8 is provided on the lifting rod, one end of the positioning block 8 is fixedly connected to the lifting rod, and the other end of the positioning block 8 abuts against the side plate of the silo 14, so that there is a gap between the lifting rod and the screw conveyor 12. Preferably, the positioning block 8 is a square block, the left end of which is fixedly connected to the lifting rod, and the right end abuts against the rear side plate 2 of the silo 14. When the lifting rod is pulled up for bridge breaking, the positioning block 8 moves with the lifting rod; when the bridge breaking is completed and the lifting rod falls, under the action of the positioning block 8, the lifting rod and the screw conveyor 12 can be prevented from being too close to each other, which would affect the normal operation of the screw conveyor, and a certain gap is maintained between the lifting rod and the blades of the screw conveyor 12.

[0031] The free end 7 of the lifting rod is suspended in the air by the steel wire rope 4. Under the pressure of the kitchen waste, the lifting rod is pressed down, causing the free end 7 of the lifting rod to approach the screw conveyor 12. Generally, a gap of 6-10 cm is set between the lifting rod and the screw conveyor 12 to prevent the lifting rod from colliding with the screw conveyor 12 under pressure.

[0032] In an optional embodiment, a counterweight 5 is provided on the steel wire rope 4 in the silo 14. Preferably, the counterweight 5 is fixed on the steel wire rope 4 below the entrance of the silo 14. When the food waste truck is unloading, the steel wire rope 4 will not be shaken randomly due to the falling garbage under the gravity of the counterweight 5. Interference between the steel wire rope 4 and the rear door of the food waste truck is avoided, ensuring orderly unloading of the food waste truck.

[0033] In an optional embodiment, the lifting rod is L-shaped, and the transverse section of the L-shape is located above the blades of the screw conveyor 12. In this embodiment, the lifting rod is set to an approximate L-shape, wherein the fixed end 6 of the lifting rod is the end of the longitudinal section, and the free end 7 of the lifting rod is the end of the transverse section. The transverse section is located above the screw conveyor, and the positioning block 8 is set at the transition position between the transverse section and the longitudinal section. In actual working conditions, the lifting rod can also be set to other shapes, and the setting position of the positioning block 8 can also be adjusted accordingly, which is not specifically limited in this application.

[0034] In an optional embodiment, the side of the lifting rod is an inclined surface. Optionally, the front side of the lifting rod can be set as an inclined surface, or the rear side of the lifting rod can be set as an inclined surface, or the front and rear sides of the lifting rod can be set as inclined surfaces. For example, the lifting rod can be set as a triangular prism, so that the front and rear sides of the lifting rod are both set as inclined surfaces, so that the kitchen waste can fall more smoothly onto the screw conveyor 12. Preferably, as Figure 2 As shown, in this embodiment, the cantilever rod is formed by welding steel plates, wherein the upper part of the cantilever rod is obliquely welded into an inverted V shape by two steel plates, and the lower part of the cantilever rod is a square channel steel or a square tube. Finally, the upper and lower parts are welded to obtain a cantilever rod with inclined front and rear sides.

However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this description.

For example, in the claims, any one of the claimed embodiments may be used in any combination.
