Description

Technical Field

[0001] This utility model belongs to the technical field of concrete mixing equipment, specifically relating to a sliding rail type double hopper device. Background Technology

[0002] The structure of the discharge port of a concrete mixing plant directly affects the material conveying efficiency and the applicability of the equipment. Currently, the most commonly used discharge device in the industry is a single funnel-shaped hopper structure. In practical applications, when processing coarse aggregate particles larger than 40mm or fiber-reinforced concrete, the single funnel-shaped structure is prone to material bridging, leading to increased discharge port blockage and decreased discharge efficiency. This is especially true for special materials such as recycled aggregate concrete, where the irregular particle shape exacerbates the frictional resistance of the guide surface, resulting in prolonged material residence time.

[0003] Existing improved solutions, such as double-sloping-plane guide devices, improve flowability by increasing the guide angle, but fail to fundamentally address the limitation in applicability caused by a single structure. Therefore, there is an urgent need to develop a discharge device that combines adaptability to multiple operating conditions with structural reliability to meet the conveying needs of different materials and improve the overall efficiency of the equipment. This paper proposes a sliding-rail type double-collecting hopper device. Utility Model Content

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, such as Figure 1-4 As shown, a sliding rail type double hopper device includes a hopper assembly 1, a hopper support 2, and a wire rope pulling device 3.

[0024] The hopper assembly 1 includes a funnel-shaped hopper 11 and a rectangular hopper 12. The funnel-shaped hopper 11 has a conical guide surface to ensure continuous sliding of powder and fine aggregate. The guide surface is made of mirror stainless steel plate to reduce the coefficient of friction. The rectangular hopper 12 is a rectangular cross-section channel, which is specially designed to handle coarse aggregate and fiber-reinforced concrete. The dual channels can be selected independently, which improves the processing efficiency compared to the single structure. The applicable aggregate particle size range is extended to 5-80mm.

[0025] Funnel-shaped hopper 11 and rectangular hopper 12 are arranged side by side and fixed by hopper frame 13. Hopper frame 13 is the structural carrier integrating funnel-shaped hopper 11 and rectangular hopper 12, bearing the impact load of the material and transmitting the traction force. The frame is made of square tube welded frame, and 20mm reinforcing ribs at the joints improve the bending stiffness. Pulley blocks 14 are provided on the outer walls of both sides of hopper frame 13. The pulley blocks 14 enable the hopper assembly 1 to slide smoothly laterally along the hopper support 2 and bear the impact load under dynamic working conditions.

[0026] The hopper assembly 1 is connected to the inner wall of the hopper support 2 via pulley blocks 14 on both sides. The hopper support 2 constitutes the main support structure of the device. The hopper support 2 is a fixed design and is fixed to the external platform without moving. A wire rope pulling device 3 is installed on the hopper support 2, which pulls the hopper assembly 1 to move.

[0027] The specific design of the aforementioned key components will be discussed in detail below:

[0028] The funnel-shaped hopper 11 and the rectangular hopper 12 are welded side by side within the hopper frame 13. The funnel-shaped hopper 11 and the rectangular hopper 12 are made of 304 stainless steel plates and welded in parallel within the hopper frame 13. The center distance between the two hoppers is 450mm. CO2 gas shielded welding is used, the weld height is 8mm, and the full weld length accounts for ≥95%. The weld meets the GB / T 3323-2005 Class II standard after UT flaw detection.

[0029] The inner side of the hopper support 2 is equipped with a double-rail I-beam guide rail. The I-beam guide rail is made of Q345B hot-rolled I-beam steel with a center distance of 1200mm between the double rails and a single rail straightness error of ≤1.5mm / m. The I-beam guide rail is connected to the hopper support 2 by M30 high-strength bolts and is installed with laser calibration.

[0030] The wire rope pulling device 3 includes a winch 31, a wire rope 32, and a fixed pulley 33. The winch 31 provides traction power and precisely controls the reciprocating motion of the hopper assembly 1. The wire rope 32 is connected to the winch 31 and transmits traction force. The wire rope 32 is connected to the hopper assembly 1 and pulls the hopper assembly 1 to move.

[0031] An angle steel is welded to the inner side of the hopper support 2, and the angle steel is used as a blocking element or limiter.

[0032] The fixed pulley 33 is installed on the bottom wall and side wall of the hopper support 2. The fixed pulley 33 changes the force transmission direction of the wire rope 32 and optimizes the traction force vector distribution.

[0033] Two sets of wire rope pulling devices 3 are provided, respectively installed at both ends of the hopper support 2. The wire rope 32 is wound on the winch 31, and the other end is connected to the hopper assembly 1. During operation, the winch 31 of one set of wire rope pulling devices 3 rotates, and the wire rope 32 extends. At the same time, the winch 31 of the other set of wire rope pulling devices 3 rotates, and the wire rope 32 shortens. The hopper assembly 1 slides in one direction. Conversely, when the rotation direction of the winches 31 of the two sets of wire rope pulling devices 3 changes, the hopper assembly 1 slides in the opposite direction.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
