Description

Technical Field

[0001] The utility model belongs to the technical field of spiral feeding, and particularly relates to a spiral feeding device. Background Art

[0002] Microbial agents such as Bacillus licheniformis, lactic acid bacteria, carboxylic acid bacteria and their metabolites can regulate the microbial ecological environment in the animal intestine because they can improve the flora in the animal intestine. Therefore, microbial agents are widely used in the industry, such as being used as active agents in aquaculture to improve the intestinal microbial ecological environment of farmed animals.

[0003] At the same time, microorganisms can also degrade pollutants in water quality to purify water quality, such as degrading animal feces.

[0004] Therefore, the industrial demand for microbial agents is relatively large. In the process of industrial production of microbial agents, microorganisms and their metabolites are mixed into the main material in proportion in the form of auxiliary materials (such as the cereal main material of feed), and then conveyed to the next mixing equipment through a screw conveyor and continue to be mixed with other materials. Therefore, the screw conveyor plays a role in material conveying in the production and processing of microbial agents, and because the screw conveyor can convey materials at different heights, it can meet the requirement of conveying materials at different height positions in the workshop during the production process (specifically, the discharge port of the equipment is at a low position and the feeding port is at a high position). At the same time, through the sealed conveying of the screw conveyor, the risk of material pollution can be reduced during the conveying process.

[0005] However, in the actual working process, since the material conveying and mixing are carried out simultaneously, and during the mixing process, the addition of auxiliary materials often needs to be slow to ensure that the auxiliary materials can be fully mixed. Therefore, the screw conveyor needs to control the conveying volume well. However, the function of the screw conveyor is only to convey materials, and it is difficult to control the feeding speed through adjustment methods. Therefore, in the actual working process, especially when the requirement for the mixing uniformity is relatively high, only manual feeding can be used, that is, the materials are fed into the feed cylinder of the conveyor in an intermittent manner. However, the disadvantages of this method are as follows: firstly, the labor intensity is large, and secondly, the feeding smoothness is low, resulting in the situation that during the actual working process, the materials have been discharged completely, and the operator cannot find and supplement the feeding in time, resulting in too long overall feeding and mixing time. Content of the Utility Model

[0006] Based on the above background, the purpose of the utility model is to provide a spiral feeding device.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0025] The utility model has the following beneficial effects:

[0026] 1. During the working process, when it is necessary to reduce the material passing amount to meet the mixing process, so that the mixing equipment can fully mix the conveyed materials with the main materials. The operator rotates the push rod (a driving wheel handle is fixedly connected to the outer end of the push rod for convenient rotation). During the rotation process, the push rod touches the material control plate, and at this time, the 4 material control plates flip towards each other. During the flipping process, the size of the material control channel gradually decreases, and at this time, the material passing amount decreases. By this method, the material passing amount can be adjusted, and after adjustment, the feeding speed can be stably maintained at this material passing amount for a long time, thereby effectively ensuring that the mixing equipment can fully mix the conveyed materials and preventing defects such as too fast feeding speed affecting the mixing sufficiency due to uncontrollable feeding speed.

[0038] Embodiment 1

[0039] As Figures 1-5 shown, a spiral feeding device includes a spiral feeder 1. The spiral feeder 1 is a conventional conveyor for conveying materials disclosed in the prior art, and its main structure is the same as the existing structure, including a feeding cylinder arranged obliquely upward. A spiral auger is rotatably connected in the feeding cylinder; the spiral feeder 1 further includes an auger motor 11 for driving the spiral auger to rotate and push materials.

[0040] To achieve controlled feeding, the feed port of the screw feeder 1 is equipped with a controlled feeding mechanism that can control the amount of material fed. During operation, another screw conveyor transfers the material to the controlled feeding mechanism, which then controls the feeding speed of the material into the screw feeder 1. For materials that are difficult to mix, the feeding speed needs to be reduced, and vice versa.

[0041] Specifically, the controlled feeding mechanism includes a hopper 12 assembled and connected to the feeding port of the spiral feeder 1 (the hopper 12 is assembled and connected to the feeding barrel), and a controlled feeding structure is installed on the top of the hopper 12.

[0042] The specific structure of the control feed structure is:

[0043] The feed control structure includes an annular rib 13 installed at the top position of the feed hopper 12 (the bottom of the annular rib 13 is fixedly connected to an annular mounting seat 23, and the annular mounting seat 23 is fixedly installed at the top position of the feed hopper 12), and a lower hopper 21 is installed above the annular rib 13 (the lower end of the outer wall of the lower hopper 21 is fixedly installed on the top of the annular rib 13 through a connecting claw), and a number of mutually cooperating material control plate assemblies are respectively installed at the lower ends of the side walls of the lower hopper 21.

[0044] Specifically, the transverse cross-section of the lower hopper 21 is a square; the front and rear side walls and the lower ends of the left and right side walls of the lower hopper 21 are all installed with material control plate assemblies 3.

[0045] The specific structure of the material control plate assembly 3 is:

[0046] The material control plate assembly 3 includes material control plates 31, which define a material control channel A between the plates 31. Correspondingly, a horizontal axis hingedly connected to the material control plates 31 is fixedly connected to the lower end of the sidewall of the lower hopper 21. The feed control mechanism also includes a push rod 35 for pushing the material control plates 31 to flip. This push rod 35 is threadedly connected to the annular rib 13. This push rod 35 pushes the material control plates 31 to flip, adjusting the size of the material control channel A between the plates 31.

[0047] Specifically, under normal circumstances, the four material control plates 31 are in a downward vertical position under the action of gravity. At this time, the material control channel A is at its largest size and the material flow rate is the fastest. However, when the material flow rate needs to be reduced to ensure that the mixing equipment can fully mix the incoming material with the main material during the mixing process (the discharge end of the spiral feeder 1 is located at the inlet of the mixing equipment), the operator rotates the push rod 35 (a drive wheel handle is fixedly connected to the outer end of the push rod 35 to facilitate rotation). During the rotation, the push rod 35 contacts the material control plate 31, and the four material control plates 31 flip towards each other. During the flipping process, the size of the material control channel A gradually decreases, and the material flow rate decreases.

[0048] In this way, the throughput can be adjusted, and after adjustment, the feeding speed at the throughput can be maintained steadily for a long time, thereby effectively packaging and mixing the transferred materials so that the defect of affecting the adequacy of mixing, such as excessive feeding speed, can be avoided due to the inability to control the feeding speed.

[0049] The material control plates 31 are triangular in shape. When the material control plates 31 are turned over to contact each other, a conical sealing structure is formed between the material control plates 31 to block the discharge port of the lower hopper 21 .

[0050] Example 2

[0051] like Figures 1-5 As shown, based on the structure of Example 1, the lower ends of the side walls of the above-mentioned lower hopper 21 are fixedly connected with horizontal mounting shafts 32, and the two ends of the horizontal mounting shafts 32 are fixedly connected with ear seat plates, which are fixedly installed on the lower hopper 21.

[0052] The top of the material control plate 31 is hingedly mounted on the horizontal mounting shaft 32 via a number of hinged locking connectors. These hinged locking connectors include a hinge sleeve 34 rotatably connected to the horizontal mounting shaft 32. The bottom of the hinge sleeve 34 is fixedly connected to a connecting arm 33, which is fixedly connected to the top of the material control plate 31. A locking screw 341 is threadedly connected to the top of the hinge sleeve 34, which is pressed and positioned on the horizontal mounting shaft 32.

[0053] When the material control plate 31 is flipped and adjusted, the operator loosens the locking screw 341 , and the material control plate 31 is flipped under the push of the push rod 35 . After flipping to a specified angle, the operator uses the locking screw 341 to lock and further position the posture of the material control plate 31 .

[0054] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
