[0053] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0054] The present invention provides a flow control feeding device, comprising:

[0055] A material flow assembly, including a material flow trough and an angle adjustment mechanism at the lower side of the material flow trough;

[0056] A plurality of flow control components are arranged inside the material flow trough, and the upper ends thereof are slidably matched with the cross beam above the material flow trough;

[0057] The transverse moving component is arranged on the crossbeam and can drive the flow control component to move transversely along the material flow trough;

[0058] The longitudinal moving components are arranged on both sides of the material flow trough and can drive the crossbeam to move longitudinally along the material flow trough.

[0059] Specifically, the trough can be formed into a U-shaped trough by bending a steel plate, and the inclination angle of the trough can be adjusted by an angle adjustment mechanism so that the material can flow down in the trough, and the flow rate and flow velocity of the material can be preliminarily controlled; multiple flow control components are arranged in a certain form inside the trough, and can guide or divert the material flowing in the trough. By combining multiple flow control components at different spatial positions in the trough, the flow rate of materials at different positions in the trough can be controlled and adjusted to meet production needs; the lateral moving component and the longitudinal moving component can drive the flow control component to move horizontally and longitudinally in the trough.

[0060] Optionally, the angle adjustment mechanism includes:

[0061] A rotating frame is arranged at the bottom of the material flow trough, and a first connecting block is arranged on the rotating frame;

[0062] A base frame, one end of which is rotatably connected to the rotating frame, and a second connecting block is provided on the base frame, and the second connecting block is slidably matched with the base frame;

[0063] The connecting rod has two ends which are rotatably connected to the rotating frame and the base frame respectively.

[0064] Specifically, the first connecting block is fixedly connected to the rotating frame, and the length of the connecting rod is fixed. The angle of the rotating frame relative to the base frame can be adjusted by adjusting the position of the second connecting block on the base frame, and then the second connecting block can be fixed on the base frame using screws or pins to determine the inclination angle of the flow trough.

[0065] Optionally, the flow control component includes:

[0066] A slider is slidably matched with the cross beam, and a first threaded hole is arranged inside the slider;

[0067] A first driving motor is mounted on one side of the slider through a first mounting seat, and the first mounting seat is slidably matched with the slider;

[0068] A cylinder is arranged on the upper side of the first mounting seat, and a telescopic end is connected to the first mounting seat;

[0069] A first screw rod is connected to the output end of the first drive motor, the upper end and the lower end of the first screw rod are respectively provided with a first bearing seat and a second bearing seat, the first screw rod is sleeved with a threaded seat, and the threaded seat is provided with a second threaded hole engaged with the first screw rod;

[0070] The dividing plate assembly is arranged on one side of the first screw rod.

[0071] Specifically, the slider can slide along the cross beam, and the first mounting seat can move up and down along the slider. The dividing plate assembly is driven up and down by the extension and contraction of the cylinder. The material flow rate is adjusted by changing the gap between the lower end of the dividing plate assembly and the bottom of the material flow trough. The first drive motor drives the first screw rod to rotate to adjust the dividing plate assembly, and the flow rate is controlled by changing the state of the dividing plate assembly.

[0072] Optionally, the dividing plate assembly includes:

[0073] A material distribution shaft, the upper end of which is connected to the lower end of the slider, and the lower end of which is connected to a connecting plate fixed on one side of the second bearing seat;

[0074] The first material dividing plate and the second material dividing plate are both rotatably connected to the material dividing shaft;

[0075] The scissor assembly comprises a first rotating plate and a second rotating plate, wherein the first rotating plate is rotatably connected to the middle of the second rotating plate, one end of each of the first rotating plate and the second rotating plate is provided with a roller, the other end of the first rotating plate is rotatably connected to the first bearing seat, and the other end of the second rotating plate is rotatably connected to the threaded seat;

[0076] Two scissor-fork assemblies are provided, which are respectively in rolling cooperation with the first dividing plate and the second dividing plate through rollers.

[0077] Specifically, the first material dividing plate and the second material dividing plate rotate around the material dividing axis to achieve the adjustable angle between the first material dividing plate and the second material dividing plate. The engagement of the threaded seat with the first screw rod allows the threaded seat to move up and down along the first screw rod, driving the second rotating plate and the first rotating plate to rotate relative to each other. At the same time, the rollers at the ends of the first rotating plate and the second rotating plate roll along the surfaces of the first material dividing plate and the second material dividing plate, pushing the first material dividing plate and the second material dividing plate to rotate around the material dividing axis, thereby changing the angle between the first material dividing plate and the second material dividing plate. The diversion and guidance effects of the first material dividing plate and the second material dividing plate on the materials are adjusted by changing the angle between the first material dividing plate and the second material dividing plate, thereby realizing the distribution of the materials in the flow trough.

[0078] Optionally, multiple flow control components are distributed in multiple stages along the flow direction of the material, with a beam set at each stage. The first stage is provided with a flow control component, and each subsequent stage has one more flow control component than the previous stage, so that the multiple flow control components are arranged in a Pascal's triangle.

[0079] Specifically, multiple flow control components arranged in a Pascal's triangle can make the probability of materials diverted by the previous level's dividing plate component flowing into the first dividing plate side and the second dividing plate side of the next level's flow control component basically equal. It is more convenient to change the diversion position of the material by changing the position of the previous level's dividing plate component, thereby more conveniently controlling the flow of materials at different positions in the flow trough.

[0080] Optionally, a return spring is sleeved on the dividing shaft, and the return spring can provide a force for the first dividing plate and the second dividing plate to fold in the direction of the first screw rod.

[0081] Optionally, the lateral movement component includes:

[0082] The second screw rod is installed on the upper side of the cross beam through the third bearing seats at both ends and cooperates with the first threaded hole;

[0083] Transverse drive assembly, comprising:

[0084] A first bevel gear is arranged at one end of the second screw rod;

[0085] A second drive motor is installed above the first bevel gear via a motor bearing seat disposed at an upper end of a third bearing seat;

[0086] The second bevel gear is connected to the output end of the second driving motor and meshes with the first bevel gear.

[0087] Specifically, the second drive motor can drive the second bevel gear to rotate, and the engagement of the second bevel gear with the first bevel gear drives the first bevel gear and the second screw to rotate, and the engagement of the second screw with the first threaded hole drives the slider to move axially along the second screw, thereby realizing lateral movement of the flow control component.

[0088] Optionally, the number of second screw rods arranged on each crossbeam is equal to the number of flow control components arranged at this stage, and a separate transverse drive component is arranged at one end of each second screw rod.

[0089] Specifically, when a plurality of flow control components are arranged in a Pascal's triangle, each flow control component is driven by its own lateral drive component, so that the flow of materials at different positions can be easily regulated.

[0090] Optionally, the longitudinal movement component includes:

[0091] Two longitudinal slide rails are respectively arranged on both sides of the material flow trough;

[0092] Two longitudinal sliding blocks are respectively arranged at the two ends of the crossbeam and are respectively slidably matched with the two longitudinal sliding rails;

[0093] A third screw rod is arranged on one side of a longitudinal slide rail;

[0094] The longitudinal driving component is arranged on one side of the third screw rod and can drive the longitudinal sliding block to move along the third screw rod.

[0095] Specifically, the longitudinal drive assembly cooperates with the third screw rod to drive the longitudinal slider to move along the longitudinal slide rail. Since the longitudinal slider is connected to the crossbeam, the crossbeam can be driven to move in the longitudinal direction of the material flow trough.

[0096] Optionally, the third screw rod is fixed to one side of the longitudinal slide rail through a fixing frame, and the longitudinal drive assembly includes:

[0097] A connecting frame, one end of which is connected to one end of the crossbeam;

[0098] A third driving motor is mounted on the other end of the connecting frame;

[0099] A first gear connected to an output end of a third driving motor;

[0100] The second gear is sleeved on the third screw rod. A third threaded hole matched with the third screw rod is arranged at the center of the second gear. The second gear is meshed with the first gear.

[0101] Specifically, the third driving motor can drive the first gear to rotate, and the second gear is driven to rotate through the meshing of the first gear and the second gear. The first gear and the second gear are both rotatably installed in a U-shaped frame fixed to the lower side of the connecting frame, and the third screw rod does not rotate. Through the cooperation between the third threaded hole and the third screw rod, when the second gear rotates, the connecting frame is driven to move axially along the third screw rod, thereby realizing the longitudinal movement of the beam.

[0142] In summary, the flow control feeding device provided by the present invention can be applied to a rice husking machine. Since the different positions of the rubber rollers of the rice husking machine will be worn to different degrees after long-term use, the gap between the rubber rollers at the position with more serious wear becomes larger, and the shelling effect becomes worse. It is necessary to increase the flow rate of grains at the position with a larger gap between the rubber rollers to ensure the shelling effect of grains. Therefore, it is necessary to adjust the grain flow rate at different positions of the feed port through the feeding device. The outlet of the flow trough 1 is placed above the rubber roller, and the inclination angle of the flow trough 1 is adjusted by the angle adjustment mechanism 2, so that the grains can flow smoothly in the flow trough 1, and the flow rate and flow rate of the grains can be preliminarily controlled. During use, the first drive motor 13 is started, and the threaded seat 19 and one end of the second rotating plate 25 are driven to move axially along the first screw rod 16 through the first screw rod 16, and then the first dividing plate 22 and the second dividing plate 23 are pushed to open and close through the opening and closing of the scissor assembly, and the dividing angle and the position of the grain falling into the first dividing plate 22 and the second dividing plate 23 of the next-level flow control assembly 3 are adjusted to control the grain flow at different positions of the flow trough 1. The gap between the lower end of the first dividing plate 22 and the second dividing plate 23 and the bottom of the flow trough 1 can be controlled by the cylinder 15 at the upper end of each flow control assembly 3, thereby controlling the flow of grains at the lower side of the first dividing plate 22 and the second dividing plate 23.

[0143] In addition, by starting the second drive motor 30, the flow control component 3 can be driven to move laterally in the flow trough 1 through the engagement of the second screw rod 27 with the first threaded hole, and the dividing position of the first dividing plate 22 and the second dividing plate 23 can be adjusted, thereby controlling the distribution of grains in the lateral direction of the flow trough 1; by starting the third drive motor 36, the crossbeam 4 can be driven to move along the longitudinal slide rail 32 through the engagement transmission of the first gear 37 and the second gear 38 and the engagement transmission of the third threaded hole and the third screw rod 34, thereby adjusting the distance between the flow control components 3 of each level, and thereby adjusting the position and angle of the grains when they pass through the first dividing plate 22 and the second dividing plate 23 of the flow control component 3 of the previous level and fall into the next level, thereby realizing the regulation of grain distribution. The device arranges multiple flow control components 3 in the form of a Pascal's triangle, so that the probability of grains flowing from the first dividing plate 22 and the second dividing plate 23 of the upper-level flow control component 3 to the first dividing plate 22 side or the second dividing plate 23 side of the lower-level flow control component 3 is basically the same. Therefore, the flow rate of grains at different positions in the flow trough 1 can be conveniently and accurately controlled by changing the position of the upper-level flow control component 3 or the angles of the first dividing plate 22 and the second dividing plate 23.

[0144] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
