Description

Technical Field

[0001] The utility model relates to the technical field of material lifting, in particular to an aggregate lifting machine. Background Art

[0002] Traditional aggregate elevators are mainly used to lift materials from low places to high places, and are widely used in mining, construction, fertilizer, grain and other industries. Most existing aggregate elevators use chains, belts or spirals to lift materials, but in actual use, these devices have some shortcomings. First, the material distribution in the aggregate hopper of traditional aggregate elevators is relatively uneven, which often leads to the inability of materials to enter the lifting hopper evenly, thus affecting the lifting efficiency of the materials. This uneven material distribution may cause some lifting hoppers to fail to be fully filled, resulting in the phenomenon of "half-bucket material", which reduces the work efficiency of the lifting process.

[0003] In addition, existing lifting equipment is often plagued by the problem of insufficient material conveying. Traditional spiral aggregate mechanisms or chain lifting devices often cause blockage or backlog in the material conveying process due to the insufficient movement of materials in the aggregate hopper. This not only affects the smoothness of lifting, but also easily causes equipment failure, thereby increasing maintenance costs. Therefore, an aggregate elevator is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an aggregate elevator. By arranging partitions in the aggregate hopper and forming multiple feeding cavities, the materials are effectively diverted to the aggregate cavities, so that the materials enter the lifting hopper more concentratedly and evenly. During the lifting process, the spiral blades drive the materials to be evenly transported into the lifting hopper through rotation, ensuring the complete filling of the lifting hopper, significantly improving the efficiency of material lifting, avoiding the half-bucket material phenomenon that may occur in traditional designs, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aggregate elevator, including an aggregate hopper and a lifting component, the lifting component including a lower shaft, an upper shaft, a chain and a lifting hopper, two chains are provided, the chains are arranged in parallel, the chains are installed between the lower shaft and the upper shaft through a sprocket, the lifting hopper is arranged between the chains, the lower shaft is arranged in the aggregate hopper, and the two ends of the lower shaft are rotatably connected with the aggregate hopper, the chain can drive the lifting hopper to circulate, the lifting hopper digs materials from the aggregate hopper, and drives the materials to be discharged upward through the sliding trough to achieve the lifting of materials, a spiral aggregate mechanism is symmetrically arranged on the lower shaft, the spiral aggregate mechanism includes spiral blades and a fixed sleeve, the fixed sleeve is passed through the lower shaft, the spiral blades are arranged on the outer surface of the fixed sleeve, the lower shaft drives the spiral aggregate mechanism to rotate, and the spiral blades on both sides drive the materials to run to the middle of the aggregate hopper, so as to achieve the concentration of materials and facilitate the lifting hopper to dig materials.

[0006] Furthermore, a partition is provided in the collecting hopper, and two partitions are provided. The partition divides the internal cavity of the collecting hopper into a left feed cavity, an collecting cavity and a right feed cavity, and the lower parts of the left feed cavity, the collecting cavity and the right feed cavity are connected. The lower end of the lifting assembly is located in the collecting cavity. The partition plays the role of dividing the material. The material can only enter the collecting cavity through the spiral blades. During the lifting process, the spiral blades also play the role of driving the material into the lifting hopper. Feeding on both sides at the same time is conducive to filling the lifting hopper, improving lifting efficiency, and reducing the situation of half-bucket material.

When the motor is started, the motor drives the upper shaft to rotate, and the upper shaft drives the lower shaft and the spiral blades on the fixed sleeve to rotate synchronously through the chain, thereby realizing material aggregation and lifting.

[0008] Furthermore, the collecting hopper is arranged on the base, a fixing plate is arranged on one side of the base, and circular holes for fixing are arranged on both sides of the fixing plate.

[0009] Furthermore, a feed port is provided on the front side of the collecting hopper, and two feed ports are provided, which correspond to the left feed cavity and the right feed cavity respectively, and the work efficiency is improved by feeding from both sides.

DETAILED DESCRIPTION

[0019] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: in this embodiment, two partitions 6 are arranged in the collecting hopper 2, which divide the internal space of the collecting hopper 2 into a left feed chamber 15, a collecting chamber 16 and a right feed chamber 17. The design of the partition 6 enables the material to be distributed according to a specific flow direction. The material first enters the left feed chamber 15 or the right feed chamber 17, and then is guided into the collecting chamber 16 by the spiral blade 8, thereby concentrating the material and ensuring that the material enters the lifting hopper 11 evenly. During the lifting process, the spiral blade 8 can not only drive the material into the lifting hopper 11, but also effectively prevent the material from being piled up or unevenly distributed. , ensuring smooth transportation of materials; the lifting component includes a lower shaft 10, an upper shaft 13, a chain 12 and a lifting hopper 11. In this embodiment, the chain 12 is connected between the lower shaft 10 and the upper shaft 13 through a sprocket device to form a closed loop. The two chains 12 are arranged in parallel. The lifting hopper 11 is installed between the chains 12 and circulates with the chains 12. The lifting hopper 11 digs materials from the collecting hopper 2 and discharges them through the sliding trough 4. The parallel arrangement of the chains 12 can ensure smooth operation during the lifting process and avoid the problem of material blockage caused by uneven or unsmooth sliding of the chains 12 in traditional elevators.

[0021] A symmetrical spiral material collection mechanism is arranged on the lower shaft 10, and the mechanism consists of a spiral blade 8 and a fixed sleeve 9. The fixed sleeve 9 passes through the lower shaft 10, and the spiral blade 8 is arranged on the outside of the fixed sleeve. When the lower shaft 10 rotates, it drives the spiral material collection mechanism to rotate, and the spiral blade 8 pushes the material in the collection hopper 2 to the collection cavity 16. This design enables the material to be evenly distributed inside the collection hopper 2, and the material is simultaneously transported to the lifting hopper through the feed cavities on both sides, thereby improving the uniformity of material filling and the lifting efficiency.

[0022] In order to further optimize the material transportation, this embodiment adopts an intelligent control system, which can monitor the operating status of the elevator in real time, and adjust the lifting speed and the tension of the chain 12 according to actual needs, so as to avoid the elevator stopping due to excessive load or material blockage. Through this automatic adjustment, the elevator can automatically adjust the working state according to the type of material, particle size and conveying volume, so as to achieve more efficient and stable material lifting; the partition 6 in the collecting hopper 2 is not only used for material diversion, but also through the connecting structure at its lower end, the left feed chamber 15, the collecting chamber 16 and the right feed chamber 17 form a material flow channel. After the material flows into the collecting chamber 16 from the feed chambers at both ends of the collecting hopper 2, it is pushed into the lifting hopper 11 through the rotation of the spiral blades 8, so as to realize the function of feeding on both sides at the same time. This design effectively avoids the concentration of materials in a certain part of the collecting hopper 2, thereby improving the efficiency of material lifting and avoiding the problem of incomplete lifting caused by uneven material distribution during the lifting process.

[0023] In order to improve the operating stability and service life of the equipment, this embodiment selects special materials and applies anti-wear treatment to key components of the lifting assembly such as the chain 12, the lifting hopper 11, the spiral blades 8, etc. The chain 12 and the sprocket are designed with wear-resistant alloy materials, and the surface of the lifting hopper 11 is coated with an anti-wear coating, which greatly reduces the wear problem caused by long-term operation. At the same time, the spiral gathering mechanism adopts an adjustable structural design, so that the angle of the spiral blades 8 can be adjusted according to the type of material and the flow state, thereby further improving the material conveying efficiency and the convenience of equipment maintenance.

[0024] When in use: the material enters the collecting hopper 2 through the feed port, and then passes through the partition 6 inside the collecting hopper 2 to be divided into the left feeding chamber 15, the collecting chamber 16 and the right feeding chamber 17; and settles to the bottom of the collecting chamber 16 under the action of gravity, and the lower part of the collecting chamber 16 is connected with the left feeding chamber 15 and the right feeding chamber 17. This design allows the material to be evenly distributed in the collecting chamber 16, avoiding uneven accumulation of the material in the collecting hopper 2. When the spiral collecting mechanism starts to work, the material is guided by the spiral blade 8 And they are concentrated into the lifting hopper 11 to ensure the stable transportation of materials during the lifting process; two parallel chains 12 are installed between the lower shaft 10 and the upper shaft 13, so that the lifting hopper 11 can circulate up and down with the movement of the chain 12, and the materials are transported to the lifting hopper 11 through the spiral collecting mechanism. When the lifting hopper 11 moves upward, it extracts the materials from the collecting cavity 16 in the collecting hopper 2 and lifts them to the top of the equipment. The lifting hopper 11 discharges the materials through the sliding chute 4 to complete the lifting process of the materials.

[0025] The basic principles, main features and advantages of the present invention are shown and described above. Without departing from the spirit and scope of the present invention, the present invention may also be subject to various changes and improvements, which are all within the scope of the present invention to be protected.
