Description

Technical Field

[0002] The quantitative feeder (or quantitative feeder) is a mechanical device designed for quantitative conveying of solid bulk materials (such as blocks, particles, powders, etc.). It is widely used in various industrial production fields that require precise control of material supply, such as cement production lines, mine dressing, building materials processing, grain processing, chemical raw material transportation, etc. In these fields, quantitative feeders play a vital role to ensure the stability and efficiency of the production process.

[0003] Quantitative feeding feeders are usually composed of a storage hopper, a screw conveyor, an electrical system, etc. The quantitative feeding of materials can adjust the discharge volume of the material through the discharge time of the screw conveyor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment: Please refer to Figures 1 to 4, A quantitative feeding machine, comprising a storage hopper 1 for storing materials. Further, an ultrasonic level gauge 12 is provided at the top of the storage hopper 1 to monitor and display the capacity of the materials in the storage hopper 1 in real time, facilitating the timely addition of materials. Preferably, a transparent observation window 13 is provided vertically on the side of the storage hopper 1 for manually observing the state of the materials in the storage hopper 1. An upper limit mark 14 and a lower limit mark 15 adapted to the transparent observation window 13 are sequentially arranged from top to bottom on the side of the storage hopper 1, enabling manual observation of the capacity of the materials in the storage hopper 1. Balance holes 2 and a feeding port 3 are horizontally spaced at the top of the storage hopper 1. The balance holes 2 are used to balance the air pressure so that the materials in the storage hopper 1 can fall smoothly; the feeding port 3 is used to add materials into the storage hopper 1. Further, the upper end of the feeding port 3 is covered with a cover plate 16 to close the feeding port 3; a plurality of buckles 17 are circumferentially spaced between the cover plate 16 and the feeding port 3 for locking the cover plate 16 and the feeding port 3. A handle 18 is fixedly connected to the top of the cover plate 16 for facilitating the opening of the cover plate 16. An air vibrator 4 is provided on the outer surface of the storage hopper 1 to drive the storage hopper 1 to vibrate, so that the materials can fall smoothly and are not easily accumulated in the hopper. A screw conveyor 5 communicating with the discharge port of the storage hopper 1 is provided at the outer bottom of the storage hopper 1. The discharge amount of the materials is adjusted by the discharge time of the screw conveyor 5, thereby realizing quantitative feeding. This is the prior art and will not be elaborated here.

[0029] This embodiment further includes a fixing ring 6, a rotating body 7, a rotating drive mechanism 9, fixed crushing teeth 10 and rotating crushing teeth 11.

[0030] Among them, the fixing ring 6 is arranged in the storage hopper 1 and fits with the inner surface of the storage hopper 1, and the fixing ring 6 can be taken out from the storage hopper 1. Specifically, as Figure 1 and Figure 3 shown, the storage hopper 1 includes a storage barrel 101 and a blanking hopper 102 arranged in sequence from top to bottom. The balance holes 2 and the feeding port 3 are arranged at the top of the storage barrel 101. The air vibrator 4 is arranged on the outer surface of the blanking hopper 102. The screw conveyor 5 communicates with the discharge port of the blanking hopper 102. The fixing ring 6 is arranged between the storage barrel 101 and the blanking hopper 102. The lower end of the storage barrel 101 is fixedly connected with an upper flange 103. The upper end of the blanking hopper 102 is fixedly connected with a lower flange 104 that matches the upper flange 103. A plurality of fixing bolts 105 are circumferentially spaced and passed through between the upper flange 103 and the lower flange 104. The storage barrel 101 and the blanking hopper 102 are detachably connected through the cooperation of the upper flange 103, the lower flange 104 and the fixing bolts 105. The storage hopper 1 adopts a split structure, which facilitates the disassembly and assembly of the fixing ring 6. As Figure 3As shown, the outer ring of the fixing ring 6 is fixedly connected with a mounting ring 19, the mounting ring 19 is sandwiched between the upper flange 103 and the lower flange 104, and the mounting ring 19 is provided with a clearance through hole 20 corresponding to each fixing bolt 105. The fixing ring 6 is fixed in the storage hopper 1 by the cooperation of the mounting ring 19, the upper flange 103, the lower flange 104, the fixing bolts 105 and the clearance through holes 20. When the fixing ring 6 needs to be disassembled, the fixing bolts 105 are removed, and then the storage barrel 101 is removed, and the fixing ring 6 can be taken out, so that it is convenient to inspect or replace other components on the fixing ring 6, and the structure is simple and easy to use.

[0031] Secondly, the rotating body 7 is rotatably arranged in the fixed ring 6, and the clearance between the rotating body 7 and the fixed ring 6 forms an annular material channel 8. Before the material enters the screw conveyor 5, it must pass through the annular material channel 8. Preferably, as Figure 2 As shown, the top of the rotating body 7 is a conical structure with a narrow top and a wide bottom, so that materials can slide down smoothly and are not easy to accumulate. A weight reduction chamber 21 is provided inside the rotating body 7 to reduce the weight of the rotating body 7, thereby facilitating rotation.

[0032] Further, such as Figure 2 As shown, the annular material channel 8 includes an annular large diameter section 801, an annular variable diameter section 802 and an annular small diameter section 803 arranged in sequence from top to bottom, and the fixed crushing teeth 10 and the rotating crushing teeth 11 are evenly distributed in the annular large diameter section 801 and the annular small diameter section 803. The distance between the fixed crushing teeth 10 and the rotating crushing teeth 11 in the annular large diameter section 801 is large, which can be used to roughly crush the material, and the agglomerated material is not easy to accumulate in the annular large diameter section 801; the distance between the fixed crushing teeth 10 and the rotating crushing teeth 11 in the annular small diameter section 803 is small, which can further crush the roughly crushed material to ensure the crushing effect and ensure that the crushed material is not easy to block the screw conveyor 5. After the annular material channel 8 adopts this structure, the material can be crushed twice, thereby ensuring the crushing effect, and the material is not easy to accumulate in the annular material channel 8, and the use effect is better.

[0033] In addition, the rotation drive mechanism 9 is arranged on the top of the fixed ring 6 and is in transmission connection with the rotating body 7. Figure 3 and Figure 4As shown, the rotary drive mechanism 9 includes a housing 901 located above the fixed ring 6, and the top of the housing 901 is in an arc shape to prevent materials from accumulating on the top of the housing 901. A plurality of support rods 902 are fixedly connected at intervals along the circumferential direction between the housing 901 and the fixed ring 6 for supporting the housing 901. A motor 903 is installed in the housing 901, and the output end of the motor 903 is transmission-connected with the rotating body 7. When the motor 903 is working, it can drive the rotating body 7 to rotate, thereby crushing the materials through the cooperation of the rotating crushing teeth 11 and the fixed crushing teeth 10.

[0034] Finally, the fixed crushing teeth 10 are fixed at intervals along the circumferential direction on the inner surface of the fixed ring 6 and are located in the annular material channel 8. The rotating crushing teeth 11 are fixed at intervals along the circumferential direction on the outer surface of the rotating body 7 and are arranged alternately with the fixed crushing teeth 10. When the rotating body 7 rotates, the materials can be crushed by the cooperation of the rotating crushing teeth 11 and the fixed crushing teeth 10, so as to prevent the agglomerated materials from clogging the screw conveyor 5.

[0035] In this embodiment, it should be noted that the air vibrator 4, screw conveyor 5 and motor 903 used in this application are all existing technologies, and the connections between the various components are also existing technologies, and their connection relationships and principles will not be repeated here.

[0036] When in use, the motor 903 drives the rotating body 7 to rotate, and the material first passes through the annular large diameter section 801, and then the fixed crushing teeth 10 and the rotating crushing teeth 11 with a larger distance are used to initially crush the material. The initially crushed material enters the annular small diameter section 803 through the annular diameter reducing section 802, and then is further crushed by the fixed crushing teeth 10 and the rotating crushing teeth 11 with a smaller distance. The material after the two crushing processes enters the screw conveyor 5, and the discharge amount of the material is adjusted by the discharge time of the screw conveyor 5, thereby realizing quantitative feeding.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
