Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of conveying technology for slightly frozen and viscous materials, specifically to a bucket screw feeder. Background Technology
[0002] Existing hoppers typically use a conveying method with rotating feeding spiral blades inside the hopper when conveying materials. When conveying slightly frozen or viscous materials, the materials are extremely prone to getting tangled on the main shaft and feeding spiral blades, causing the materials to be unable to be conveyed downwards normally. Utility Model Content
[0003] To address the shortcomings and deficiencies of current technology, this utility model proposes a bucket-type feeding device. The technical solution is as follows:
[0004] This utility model proposes a bucket-type screw feeding device, including a feeding screw blade disposed in a bucket. The feeding screw blade is connected to a power shaft to drive the feeding screw blade to rotate. A belt screw blade is also disposed on the power shaft above the feeding screw blade. A material blocking screw blade is disposed in the gap between the belt screw blade and the power shaft. The material blocking screw blade is fixedly disposed so that the belt screw blade and the feeding screw blade are in a fixed state when rotating with the power shaft. Multiple guide strips are disposed at intervals along the feeding direction on the circumference of the inner wall of the bucket on one side of the feeding screw blade and the belt screw blade.
[0005] As a preferred embodiment of the above technical solution, the gap between the belt-type helical blade and the power shaft gradually decreases from top to bottom.
[0006] As a preferred embodiment of the above technical solution, the fixing point between the belt-type helical blade and the power shaft is located at the bottom of the belt-type helical blade.
[0007] As a preferred embodiment of the above technical solution, a material blocking bar is also provided in the hopper on one side of the power shaft.
[0008] As a preferred embodiment of the above technical solution, the resisting rod is cylindrical.
[0009] As a preferred embodiment of the above technical solution, the material blocking bar is disposed on the moving mechanism to be close to or away from the power shaft.
[0010] As a preferred embodiment of the above technical solution, the feeding spiral blades are disposed inside the hopper discharge port.
[0011] This utility model proposes a bucket-type screw feeding device. With the cooperation of belt-type screw blades, fixed-state material-blocking screw blades, and material guide strips on the inner wall of the hopper, the feeding screw blades can effectively solve the problem of the feeding screw blades accumulating on the feeding screw blades and spinning idly when conveying slightly frozen materials and viscous materials, thus preventing material from being discharged. Its structure is reasonable and the conveying is stable. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0022] This utility model proposes a bucket-type screw feeding device, including a power shaft 3 disposed in the hopper 1, the power shaft 3 being connected to a power unit 2 to drive the power shaft to rotate, and a feeding screw blade 7 disposed on the power shaft, the feeding screw blade 7 being disposed in the feeding port of the hopper.
[0023] A pressing auger 4 is installed on the power shaft above the feeding auger blades. The pressing auger uses ribbon-type spiral blades, and the feeding auger uses solid spiral blades. A blocking spiral blade 6 is installed in the gap between the ribbon-type spiral blades and the power shaft. The blocking spiral blade is fixed so that the ribbon-type spiral blades and the feeding auger blades are in a fixed state when they rotate with the power shaft. The blocking spiral blade 6 is fixed to the upper support of the hopper through a connecting rod. The power unit 2 is also installed on the support. Multiple guide strips 5 are spaced apart along the feeding direction on the circumference of the inner wall of the hopper on one side of the feeding auger and the pressing auger.
[0024] The gap between the belt-type spiral blade and the power shaft gradually decreases from top to bottom. The lower end of the belt-type spiral blade used in the pressing auger is fixed to the power shaft, while the upper end is not fixed to the power shaft, so that the upper part of the belt-type spiral blade is in an open state.
[0025] A material blocking rod 8 is also provided in the hopper on one side of the power shaft. The material blocking rod is columnar and is set on the moving mechanism to move closer to or away from the power shaft. The moving mechanism is a guide rail and a slider set on the bracket.
[0026] This utility model proposes a bucket-type screw feeding device. With the cooperation of belt-type screw blades, fixed-state material-blocking screw blades, and material guide strips on the inner wall of the hopper, the feeding screw blades can effectively solve the problem of the feeding screw blades accumulating on the feeding screw blades and spinning idly when conveying slightly frozen materials and viscous materials, thus preventing material from being discharged. Its structure is reasonable and the conveying is stable.
[0027] This description illustrates the technical solutions of this utility model, but is not intended to limit them. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
