Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screw conveyors, in particular to a feeding parent-child screw conveyor. Background Art
[0002] Among existing material conveying technologies, screw conveyors are a commonly used continuous conveying device that utilizes the rotational motion of spiral blades to transport materials. Screw conveyors are widely used in material conveying operations in industries such as grain, chemicals, building materials, and coal. However, traditional screw conveyors have limitations when handling materials of varying particle sizes or with varying conveying requirements.
[0003] Traditional screw conveyors usually have a single conveying diameter. When conveying materials of different particle sizes, they may not be able to meet the requirements of high-efficiency conveying of large particle materials and refined conveying of small particle materials at the same time.

[0015] The present invention will be further described below with reference to specific embodiments. It should be understood that the following specific embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.
[0016] Example: Figure 1-2 As shown, a feeding mother-and-child screw conveyor includes: a main screw conveyor 100 located on the upper side; and an auxiliary screw conveyor 200 located on the lower side; wherein, the conveying diameter of the main screw conveyor 100 is larger than the conveying diameter of the auxiliary screw conveyor 200, and the feed port of the auxiliary screw conveyor 200 is located below the feed port of the main screw conveyor 100, and the feed port of the auxiliary screw conveyor 200 is connected to the feed port of the main screw conveyor 100 through a valve 300.
[0017] Main screw conveyor 100: Located on the upper side, it is designed with a larger conveying diameter and is suitable for conveying larger amounts of materials.
[0018] The auxiliary screw conveyor 200 is located at the lower side of the main screw conveyor 100 and has a smaller conveying diameter, which is suitable for fine processing and conveying of materials. The spiral blades of the auxiliary screw conveyor 200 are designed to have a smaller pitch to adapt to the conveying requirements of smaller or powdered materials.
[0019] The feed port of the auxiliary screw conveyor 200 corresponds to a position below the feed port of the main screw conveyor 100 and is controlled by a valve 300 so that the material flows from the main screw conveyor 100 to the auxiliary screw conveyor 200 .
[0020] Through the control of the valve 300, the auxiliary screw conveyor 200 can be flexibly opened or closed according to production needs, so that the entire conveying system can be adjusted according to the characteristics of the material and process requirements.
[0021] The auxiliary screw conveyor 200 is connected to the main screw conveyor 100 via a flexible pipe 400 .
[0022] One end of the main screw conveyor 100 and the auxiliary screw conveyor 200 are rotatably connected by a rotating connector 500. The rotating connector 500 is specifically a frame structure, and its upper end is connected to the main screw conveyor 100. The auxiliary screw conveyor 200 is inserted into the bottom end of the frame of the rotating connector 500 and is connected to the rotating connector 500 via a rotating shaft.
[0023] The flexible conduit 400 is used to connect the main screw conveyor 100 and the auxiliary screw conveyor 200, allowing a certain amount of spatial displacement and angular change between the two, thereby improving the adaptability and flexibility of the system. The rotating connector 500 is located at one end between the main screw conveyor 100 and the auxiliary screw conveyor 200, allowing the two to rotate relative to each other to achieve angle adjustability. The rotating connector 500 allows the auxiliary screw conveyor 200 to be adjusted in angle relative to the main screw conveyor 100. This adjustability helps to adapt to the layout requirements of different production lines, and can be adjusted during installation and maintenance to optimize the conveying path.
[0024] By adjusting the angle of the auxiliary screw conveyor 200, the flow direction and speed of the material can be changed, thereby better controlling the material conveying process, especially in situations where precise control of material distribution is required.
[0025] A support frame 600 is provided at the bottom of the other end of the auxiliary screw conveyor 200 .
[0026] A support plate 700 is provided in the support frame 600 , and an adjusting screw 800 is provided at the bottom end of the support plate 700 . The adjusting screw 800 is screwed into the bottom end of the support frame 600 through a thread, and the upper end of the adjusting screw 800 is rotatably connected to the bottom end of the support plate 700 .
[0027] The support plate 700 is V-shaped, and the outlet end of the auxiliary screw conveyor 200 is mounted on the support plate 700 .
[0028] The support frame 600 is located at the bottom of the other end of the auxiliary screw conveyor 200 and is used to support the weight of the entire auxiliary screw conveyor and maintain its stability.
[0029] The support plate 700 is disposed in the support frame 600 and is used to directly support the outlet end of the auxiliary screw conveyor 200 .
[0030] The adjusting screw 800 is located at the bottom end of the support plate 700 and is connected to the bottom end of the support frame 600 through a thread, and its upper end is rotatably connected to the bottom end of the support plate 700.
[0031] The design of the support frame 600 ensures the stability of the auxiliary screw conveyor 200 during operation and prevents the equipment from moving due to vibration or impact of materials.
[0032] The adjusting screw 800 allows the operator to adjust the height of the support plate 700 by rotating the screw, thereby fine-tuning the outlet end position of the auxiliary screw conveyor 200 .
[0033] The support plate 700 is V-shaped, which helps to concentrate the material flow, prevent the material from scattering during the unloading process, and improve the accuracy and efficiency of material transportation.
[0034] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features.
