Description

Technical Field

[0001] The utility model belongs to the technical field of conveying equipment, and in particular relates to a combined trough-type auger feeder. Background Art

[0002] Grain, soybean meal and other materials are usually stored in silos for a long time. In order to increase the storage capacity, most companies have built large cylindrical flat-bottomed silos, but with this comes the problem of how to get the materials out of the silo and dump them. In the past, the common method was to rely on the material's own fluidity to automatically slide the material, and then use manual bottom cleaning. Another method was to use a spiral auger to force the material out (the auger is a machine that uses a motor to drive the spiral to rotate and push the material to achieve the purpose of transportation).

[0003] However, due to the poor fluidity and easy agglomeration of some materials, it is difficult to discharge and empty the silo automatically. Even if a spiral auger is used for discharge and emptying, the auger shaft will be subject to the reaction force of the material while pushing the material. Once the material agglomerates in the silo, the auger shaft is easily locked by the material and cannot be started normally. At this time, the auger shaft needs to be reversed to loosen the material, which will greatly affect the efficiency of material discharge, and cause serious wear of the equipment blades, difficulty in replacement, and high cost of renewal. In addition, the conventional spiral auger has a small feeding capacity and cannot deliver materials quickly over long distances. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 5 As shown, a combined trough-type auger feeder provided in this embodiment mainly includes a multi-joint auger and a conventional trough-type conveying auger 5, wherein the multi-joint auger includes a housing 1 and a plurality of auger discharging mechanisms. The plurality of auger discharging mechanisms are arranged in parallel in the housing 1, and the auger discharging mechanism includes an auger shaft 201, a spiral blade 202, a motor 3 and a reducer 4. The two ends of the auger shaft 201 are rotatably connected to the two sides of the housing 1 through bearings, one end of the auger shaft 201 is connected to the output shaft of the motor 3 through a coupling, and a reducer 4 is also arranged between the motor 3 and the auger shaft 201. The two ends of the same auger shaft 201 are respectively welded and fixed with spiral blades 202 with opposite spiral directions, and the spiral blades 202 extend to the middle of the auger shaft, and are used to convey the materials entering the two sides of the housing to the middle discharge port 102. In order to solve the problem of material agglomeration, the spiral blades 202 on the same side of the adjacent auger shafts 201 are in opposite directions to facilitate the crushing of agglomerated materials. The upper part of the shell 1 is completely open and directly connected to the material storage silo as a feed port 101 without the need for other support structures; a discharge port 102 is provided in the lower middle section of the shell 1, and the discharge port 102 is connected to the feed port of the trough-type conveying auger 5.

[0025] When feeding, the combined trough-type auger feeder is directly connected to the silo for discharging, without the need for other support structures. The auger shaft 201 is connected to the output end of the motor 3, and the reducer 4 is arranged between the auger shaft 201 and the motor 3 to match the rotation speed and transmit torque. The rotation of the auger shaft 201 is controlled by the motor 3 and the reducer 4. The spiral blades 202 at both ends of the auger shaft 201 are in opposite directions, forming a two-way intermediate discharging structure. The material enters from the feed port 101 at the upper part of the shell 1. When the motor 3 drives the auger shaft 201 to rotate, the material is affected by the normal thrust of the spiral blade 202, moves toward the middle along the auger shaft 201, and enters the trough-type conveying auger 5 from the discharge port 102 when reaching the middle section of the shell 1, and the trough-type conveying auger 5 continues to transport over a long distance.

[0026] The trough conveying auger 5 is an existing common auger, such as a U-shaped auger, which can be up to 30 meters long and can realize long-distance material transportation. In order to realize multi-point discharge, multiple material outlets can be opened on the trough conveying auger 5.

[0027] In some embodiments, one motor 3 is usually used to drive one auger shaft 201. However, in order to reduce energy consumption, one motor 3 can also be used to drive multiple auger shafts 201. For example, the same side ends of two adjacent auger shafts 201 are connected through a synchronous belt drive. In this case, only one motor 3 is needed to directly drive one of the auger shafts 201, and the other auger shaft will rotate under the transmission of the synchronous belt. Figure 1 As shown, in this embodiment, there are eight auger discharging mechanisms, that is, eight auger shafts 201 are arranged side by side, and every two auger shafts 201 share one motor 3.

[0028] In some embodiments, in order to further enhance the breaking effect of agglomerated materials, a plurality of cutting blades may be provided on the auger shaft 201 and / or the spiral blade 202 .

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Under the idea of ​​the present invention, the technical features in the above embodiments or different embodiments can also be combined, and there are many other changes in different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
