Description

Technical Field

[0001] This utility model relates to the field of material distribution equipment technology, and in particular to a material distribution device with feedback adjustment function. Background Technology

[0002] In recent years, with the rapid development of the economy, the demand for oil products has been increasing, and the capacity for oil processing and the degree of mechanization and automation in the production process have been greatly improved. Among them, low-temperature soybean meal can be used to produce food-grade concentrated protein, while another product, protein meal, can be used to produce feed-grade concentrated protein. As a result, the concentrated protein market has grown rapidly in recent years, and the annual production of soybeans and concentrated protein has been increasing year by year.

[0003] In the existing technology, conventional material distribution devices often only have the function of distributing materials. They are difficult to automatically handle when the material accumulation is too large or too small. When the material accumulation is too large, the equipment is easily damaged due to overload, which affects the equipment life. When the material accumulation is too small, the equipment may run idle, wasting energy and accelerating the wear and tear of various parts. Utility Model Content

[0004] This application provides a material distribution device with feedback adjustment function, which can automatically adjust the discharge speed, i.e. the material distribution speed, when there is too much or too little material in the material distribution bin, thereby solving the problems in the prior art where excessive material accumulation affects equipment life and insufficient material accumulation affects work efficiency.

[0005] This application provides a material dispensing device with feedback adjustment function, including a housing, a dispensing bin, an inlet and an outlet at the top and bottom of the dispensing bin, respectively, and an outlet shaft system near the bottom of the dispensing bin. The outlet shaft system includes a geared motor, a rotor, and outlet blades evenly distributed on the rotor. The rotor is coaxially connected to the output shaft of the geared motor. A high-level sensor and a low-level sensor for sensing the material height in the dispensing bin are respectively provided at the upper and lower parts of the dispensing bin. The high-level sensor and the low-level sensor are respectively connected to a controller, and the controller is electrically connected to the geared motor.

[0006] In one possible implementation, the material distribution bin is provided with inclined baffles, each baffle having a high end and a low end. The high end of the baffle is connected to the rear sidewall of the material distribution bin, and the low end of the baffle extends obliquely downward and close to the front sidewall of the material distribution bin. The discharge shaft system is located between the low end of the baffle and the front sidewall of the material distribution bin.

[0007] In one possible implementation, the baffle plate has an inclination angle of 40° to 50°.

[0008] In one possible implementation, a discharge adjustment mechanism is installed on the front sidewall of the distribution bin. The discharge adjustment mechanism is located above the discharge shaft system and includes a door shaft and a door. The door shaft extends along the extension direction of the rotor and is rotatably connected to the two side walls of the distribution bin. Gears are spaced apart on the door shaft. The two ends of the door are clearance-fitted with the two side walls of the distribution bin. The rear side of the door is slidably fitted with the front sidewall of the distribution bin. The front side of the door is provided with a rack or teeth that mesh with the gears, so that the door can be driven to move closer to or further away from the discharge blades when the door shaft rotates.

[0009] In one possible implementation, the door hinge has a handle mounted on either end protruding from the dispensing bin.

[0010] In one possible implementation, a bushing is fitted onto one end of the insertion shaft near the handle. The bushing is fixedly embedded in the side wall of the material distribution bin. A first limiting plate is connected to the outer end of the bushing. A first limiting hole is formed on the first limiting plate along the rotation direction of the insertion shaft. A second limiting plate that cooperates with the first limiting plate is connected to the handle. A second limiting hole is formed on the second limiting plate along the rotation direction of the insertion shaft. The first limiting plate and the second limiting plate are connected by a fixing bolt, which passes through both the first limiting hole and the second limiting hole.

[0011] In one possible implementation, the front sidewall of the material distribution bin is provided with an observation mirror, which is located above the material discharge adjustment mechanism.

[0012] In one possible implementation, the rotor is connected to a first shaft head and a second shaft head at its two ends, respectively. Both the first shaft head and the second shaft head pass through the side wall of the material distribution bin via a bearing structure. The first shaft head is connected to the output shaft of the geared motor at its outer end via a coupling, and the second shaft head is coaxially fitted with a speed measuring disc at its outer end.

[0013] In one possible implementation, the rotor is a seamless tube.

[0014] In one possible implementation, the feed inlet and discharge outlet of the material distribution bin are respectively equipped with an upper connecting flange and a lower connecting flange.

[0015] Beneficial effects: Compared with the prior art, the material distribution device with feedback regulation function provided in this application sets high-level sensors and low-level sensors in the upper and lower parts of the material distribution bin, respectively. When too much material accumulates in the material distribution bin, the high-level sensor sends a signal to the controller to control the speed of the geared motor to increase, thereby accelerating the material flow and preventing equipment overload. When too little material accumulates in the material distribution bin, the low-level sensor sends a signal to the controller to control the speed of the geared motor to decrease, thereby allowing the material to flow slowly and preventing the equipment from running idle. This can solve various problems that may exist in the prior art due to excessive or insufficient material accumulation. The overall structure is simple and the equipment cost is low.

[0016] By installing baffles in the distribution bins, the materials in the distribution bins can first contact the baffles and then slide to the top of the discharge shaft system, which can buffer the materials and reduce the direct impact of the materials on the discharge shaft system.

[0017] Among them, the gap between the blades and the side wall of the material distribution bin above the blades can be flexibly adjusted through the discharge adjustment mechanism, thereby adjusting the speed of material output by the discharge shaft system, making it more convenient to use;

[0018] The rotor is made of seamless steel pipe, which can greatly reduce the weight of the discharge shaft system.

[0019] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0026] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0028] refer to Figures 1 to 5This application provides a material distribution device with feedback adjustment function, including a housing 10. The housing 10 is provided with a material distribution bin 101. The top and bottom of the material distribution bin 101 are respectively provided with an inlet 102 and an outlet 103, which are used to receive materials conveyed from the upper-level equipment and unload materials to the lower-level equipment, respectively. In addition, for ease of installation, the inlet 102 and outlet 103 of the material distribution bin 101 are respectively equipped with an upper connecting flange 11 and a lower connecting flange 12. The material distribution bin 101 has an outlet shaft system 20 near the bottom. The discharge shaft system 20 includes a geared motor 21, a rotor 22, and discharge blades 23 evenly distributed on the rotor 22. The rotor 22 is coaxially connected to the output shaft of the geared motor 21, so it can be driven by the geared motor 21 to rotate in a directional and constant speed. The discharge blades 23 on the surface of the rotor 22 then complete the material distribution and discharge to the discharge port. In addition, the upper and lower parts of the material distribution bin 101 are respectively provided with a high level sensor 13 and a low level sensor 14 for sensing the material height in the material distribution bin 101. The high level sensor 13 and the low level sensor 14 are respectively connected to a controller, and the controller is electrically connected to the geared motor 21. When the material height in the distribution bin 101 reaches or exceeds the high-level sensor 13, it indicates that a special situation in the previous process may have caused a blockage. The high-level sensor 13 sends a signal to the controller (computer), which controls the variable frequency speed regulation of the geared motor 21, increasing the speed of the rotor 22 to accelerate the passage of material. Similarly, when the material height is lower than the low-level sensor 14, the low-level sensor 14 cannot detect the material and sends a signal to the controller. The controller controls the variable frequency speed regulation of the geared motor 21, slowing down the speed of the rotor 22 to facilitate the passage of material slowly and prevent the equipment from running idle for a long time. This feedback regulation can solve various problems that may exist in the prior art due to excessive or insufficient material accumulation. At the same time, the overall structure of this distribution device is simple, the equipment cost is low, the control is convenient, and the maintenance is easy.

[0029] In one embodiment, the material distribution bin 101 is provided with inclined baffles 15, wherein the baffles 15 have a high end and a low end, wherein the high end of the baffles 15 is connected to the rear side wall of the material distribution bin 101, and the low end of the baffles 15 extends obliquely downward and close to the front side wall of the material distribution bin 101, and the discharge shaft system 20 is located between the low end of the baffles 15 and the front side wall of the material distribution bin 101. In this way, the material entering from the inlet 102 will first fall to the baffles 15, and then slide down to the discharge shaft system 20 for distribution, thereby the baffles 15 can buffer the material and prevent the material from directly impacting the discharge shaft system 20. The inclination angle of the baffles 15 is preferably 40° to 50°, for example 45°.

[0030] In one embodiment, a discharge adjustment mechanism 30 is installed on the front side wall of the dispensing bin 101. The discharge adjustment mechanism 30 is located above the discharge shaft system 20 and includes a door shaft 31 and a door 32. The door shaft 31 extends along the extension direction of the rotor 22 and is rotatably connected to the two side walls of the dispensing bin 101. Gears 311 are spaced apart on the door shaft 31, for example, one gear 311 symmetrically on each side, or three gears 311 evenly distributed. The two ends of the door 32 are clearance-fitted with the two side walls of the dispensing bin 101, and the rear side of the door 32 is slidably fitted with the front side wall of the dispensing bin 101. The front side of the door 32 is provided with a rack or teeth 321 that mesh with the gears 311, so that when the door shaft 31 rotates, it can drive the door 32 to move closer to or further away from the dispensing bin 101. The discharge blade 23 can be adjusted by vertically moving the insertion gate 32 to change the gap between the discharge blade 23 and the front wall of the distribution bin 101. When there is only a very small gap between the bottom of the insertion gate 32 and the outer ring of the discharge blade 23, the rotor 22 drives the discharge blade 23 to rotate and discharge material evenly. At this time, the discharge speed is the slowest when the rotor 22 rotates at a constant speed. When there is too much material accumulation, the insertion gate shaft 31 can be rotated, and the insertion gate 32 can be moved upward based on the cooperation of the gear 311 and the rack or tooth 321, increasing the gap between the insertion gate 32 and the discharge blade 23, thereby accelerating the discharge. This can be combined with the reduction motor 21 to further accelerate or slow down the discharge, thereby improving the responsiveness of the distribution device and increasing its working efficiency.

[0031] In one embodiment, the insertion shaft 31 is equipped with a handle 33 at either end protruding from the dispensing bin 101 for convenient rotation of the insertion shaft 31.

[0032] More preferably, a bushing 34 is fitted onto one end of the insertion shaft 31 near the handle 33, wherein the bushing 34 is fixedly embedded in the side wall of the material distribution bin 101, and a first limiting plate 35 is connected to the outer end of the bushing 34. At the same time, a first limiting hole 301 is opened on the first limiting plate 35 along the rotation direction of the insertion shaft 31. Correspondingly, a second limiting plate 36 that cooperates with the first limiting plate 35 is connected to the handle 33, wherein a second limiting hole 302 is opened on the second limiting plate 36 along the rotation direction of the insertion shaft 31. The first limiting plate 35 and the second limiting plate 36 are connected by a fixing bolt 37, and the fixing bolt 37 passes through both the first limiting hole 301 and the second limiting hole 302. When it is necessary to move the insertion gate 32 up or down, the operator first loosens the fixing bolt 37, then rotates the insertion gate shaft 31. After rotating to the correct position, the fixing bolt 37 is tightened again. During the rotation, the cooperation of the fixing bolt 37, the first limiting hole 301 and the second limiting hole 302 can ensure the stability of the rotation of the insertion gate shaft 31 and the accuracy of the rotation direction. After tightening the fixing bolt 37, the insertion gate shaft 31 can be firmly fixed, preventing the insertion gate 32 from moving again and changing the size of the gap between the insertion gate 32 and the discharge blade 23.

[0033] Preferably, the rotational extension angle of the first limiting hole 301 and the second limiting hole 302 is 120°.

[0034] In one embodiment, the front sidewall of the dispensing bin 101 is provided with an observation mirror 16, which is located above the discharge adjustment mechanism 30, allowing observation of the material inside the dispensing device. The observation mirror 16 can be made of plexiglass.

[0035] In one embodiment, the rotor 22 is connected to a first shaft head 221 and a second shaft head 222 at both ends. Both the first shaft head 221 and the second shaft head 222 penetrate the side wall of the distribution bin 101 via bearing structures (generally including mating bearings and bearing housings). The first shaft head 221 is connected to the output shaft of the geared motor 21 at its outer end via a coupling 24. The second shaft head 222 has a speed measuring disk 25 coaxially mounted on its outer end. The speed measuring disk 25 can be monitored in real time by an infrared speed measuring probe, which then transmits the real-time results to the computer control system, i.e., the controller, to provide feedback on the speed of the geared motor 21.

[0036] In one embodiment, the rotor 22 is a seamless tube, such as a Φ76×4 seamless tube, which can greatly reduce the weight of the rotor 22, that is, the weight of the discharge shaft system 20, making it more convenient to use.

[0037] It should be noted that the terms "first" and "second" used in this application are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
