In this case, the only way is to use the material storage method. If the high-humidity material is directly put into the material warehouse, it will be difficult to discharge the material after entering the warehouse, or it may be impossible to discharge the high-humidity material that is easy to arch or clump. Therefore, it is necessary to design a material separation device that can separate the excess product material. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] like Figure 1 and Figure 2 As shown, a material dividing device in this embodiment is mainly used to divide high-humidity materials. Of course, it can be understood that it can also divide non-high-humidity materials. The material form is powder or granular. The material is, for example, feed, feed additives, raw materials of fertilizers used in the research and development of composite microorganisms, or other materials. The material dividing device is arranged at the discharge of conveying equipment such as belt conveyors or scraper conveyors, and includes a screw conveyor 1 and a material receiving cover 2, wherein the screw conveyor 1 is used to quantitatively convey the material to meet the output requirements of normal production, and the material receiving cover 2 receives the material discharged from the conveying equipment such as belt conveyors or scraper conveyors, and assumes the function of separating the excess material. The discharged material can be put into the material bin after, for example, a drying process. Since only the discharged material is stored, it can avoid the situation where the material bin is overfilled and cannot be stored.

[0026] Specifically, first, Figure 2 As shown, the material receiving hood 2 is a hollow structure that passes through from top to bottom, forming an inner space, the upper part of the inner space is the material inlet, and the lower part of the inner space is the material outlet. The material receiving hood 2 is connected to the inlet of the screw conveyor 1 through the material outlet. In this way, when feeding at the material inlet, the material will directly enter the screw conveyor 1 from the material outlet to meet normal production needs, and an inclined portion 21 is provided on the side of the material receiving hood 2. The inclined portion 21 is an inclined design, for example, forty-five degrees, and the inclined portion 21 has a discharge channel 22 connected to the inner space. In this way, when the material product is too high, the inner space will gradually accumulate. When the material accumulates in the inner space, the material will discharge the excess material through the discharge channel 22 to achieve material separation.

[0027] Secondly, to facilitate understanding of the screw conveyor 1, the screw conveyor 1 includes a cylinder shell 11, a spiral blade 12 and a driving component 13, wherein the spiral blade 12 is arranged in the cylinder shell 11 and driven by the driving component 13, and a discharge port 17 is arranged at the bottom of the cylinder shell 11, and the material discharged from the discharge port 17 is used to meet the material output required by the normal production line.

[0028] Further, as a preferred embodiment, Figure 3 As shown, the spiral blade 12 is a variable pitch spiral, and its pitch gradually increases from left to right. Taking the middle as an example of a normal pitch, the pitch of the spiral blade 12 is designed to be 0.5-1.5 times from left to right. When designed in this way, since the pitch of the spiral blade 12 on the screw conveyor 1 gradually increases from the material inlet end to the material outlet end, the material inlet amount is smaller than the outlet amount, which can overcome the problem that the screw conveyor 1 is easily blocked and stuck.

[0029] Of course, it is understandable that in other embodiments, when the material is non-wet, the spiral blades 12 may also be designed with the same pitch.

[0030] In order to allow the driving component 13 to drive the spiral blade 12, the description of the driving component 13, in a certain embodiment, as shown in FIG. Figure 4 As shown, the driving component 13 includes a motor 131, a pulley 132, a pulley 133 and a transmission belt 137. The pulley 132 is assembled at the output end of the motor 131, and the pulley 133 is connected to the spiral blade 12. The pulley 132 and the pulley 133 are both connected to the transmission belt 137, so that when the motor 131 is working, the pulley 132, the transmission belt 137 and the pulley 133 work, thereby driving the spiral blade 12 to work.

[0031] To further explain, a base plate 14 is fixed to the outside of the cylinder shell 11 by bolts, a motor 131 is fixed to the outside of the base plate 14 by bolts, a bracket 15 is welded to the side of the base plate 14 away from the material receiving cover 2, the cross-section of the bracket 15 is L-shaped, a transmission box 16 is supported on the bracket 15, the transmission box 16 is fixed to the bracket 15 by welding, and the pulley 1 132, the transmission belt 137 and the pulley 2 133 are all located in the transmission box 16.

[0032] It should also be noted that the motor 131 is variable frequency, so that the material conveying amount of the screw conveyor 1 can be adjusted according to demand. Since the frequency conversion of the motor 131 is a prior art, it will not be elaborated here.

[0033] In order to prevent the inner space from being blocked, in a certain embodiment, Figure 3As shown, the material dividing device also includes a lifting component 3, which is located in the inner space and is driven by a driving component 13. In this way, although the load of the driving component 13 will be increased, there is no need to equip an additional power source for lifting and adjusting the lifting component 3, which can reduce the space layout and save procurement costs.

[0034] During operation, when the driving component 13 is working, the lifting component 3 needs to move up and down, so that the lifting component 3 can poke and dredge the material, which can reduce the agglomeration of the wet material and make the inner space less likely to be blocked.

[0035] As for the description of the lifting component 3, the lifting component 3 includes a movable frame 31 and a plurality of inclined bars 32, wherein the movable frame 31 is fitted with the inner wall of the material receiving cover 2, and the plurality of inclined bars 32 are welded and arranged on the inner wall of the movable frame 31, and the inclined bars 32 are arranged to be inclined downward, and the agglomeration processing of the wet material is mainly completed by the inclined bars 32.

[0036] It should be noted that the movable frame 31 and the plurality of inclined bars 32 are preferably made of 304 stainless steel, which is not prone to corrosion and has a good service life.

[0037] When the driving component 13 is used as a common power source for the lifting component 3 and the spiral blade 12, as shown in FIG. Figure 4 As shown, the driving component 13 also includes a pulley three 134, a transmission rod 135 and a cam 136, wherein the pulley three 134, the pulley one 132 and the pulley two 133 are all connected to the transmission belt 137, the cam 136 and the pulley three 134 are both assembled on the outside of the transmission rod 135, and the cam 136 is located in the inner space and placed at the bottom of the moving frame 31.

[0038] It should be noted that there are two groups of cams 136, and both groups of cams 136 are located at the bottom of the movable frame 31. When they rotate, they are used to make the lifting component 3 move up and down in a cycle. In addition, a positioning column is rotatably connected to the transmission box 16, and the transmission belt 137 is connected to the positioning column.

[0039] In this way, the entire working process is as follows: when working, the motor 131 is started. By designing the transmission belt 137, the motor 131 can simultaneously drive the pulley three 134, the pulley one 132 and the pulley two 133. Among them, the pulley two 133 will drive the spiral blade 12 to work, so as to realize the material distribution required by the normal production line. The pulley three 134 drives the transmission rod 135 and the cam 136 to rotate, so that the movable frame 31 and several inclined bars 32 in the lifting component 3 move up and down. The inclined bars 32 poke the agglomeration of the wet material to reduce the agglomeration phenomenon and avoid blockage. In addition, in this process, when the material is accumulated in the inner space, the material will be discharged through the discharge channel 22 to discharge the excess material, so as to realize the material distribution.

[0040] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
