Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, and more specifically, to a material shunting device. Background Art

[0002] During the process of loading bulk materials into a vehicle, after the bulk materials fall from a conveying equipment or a silo, they vertically drop into a shunting funnel for shunting, and then slide into the carriage through a main discharging chute or a secondary discharging chute. A flap with a rotating shaft is usually installed in the shunting funnel. When the flap rotates around the shaft to a certain angle, the vertically falling bulk materials will slide along the flap, so as to achieve flow disturbance and shunting.

[0003] At present, single-flap shunting is adopted, but it has the following disadvantages: First, the control stroke is large and the speed is slow; second, the drive and the flap shaft are connected through mechanical transmission, and the force transmission efficiency is low; third, the flap shaft is located below the middle of the funnel. When the materials fall and press on the flap, the flap shaft is subjected to a large moment, and a high-power drive device needs to be assembled to drive it.

[0004] There is also a shunting method using an impeller feeding device, but the impeller feeding device has the following disadvantages: First, the speed of quantitative feeding by impeller rotation is slow, and it is difficult to meet the requirements of the loading speed in most factories; second, the box body of the impeller structure is thick, occupying a large vertical space, and does not meet the chute installation space conditions in most factories.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of 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 belong to the scope of protection of the present utility model.

[0032] The core of the present utility model is to provide a material diversion device that can achieve fast response to meet the high-precision requirements for loading weight.

[0033] Please refer to Figures 1 - 3, a material diversion device, comprising a material distribution hopper 1 and a diversion assembly 3. Two material distribution pipes 2 are connected to the lower part of the material distribution hopper 1 and form a Y-shaped structure. The diversion assembly 3 includes two diversion plates 301 that control the material flow rate into the material distribution pipes 2 by rotating the angle.

[0034] It should be noted that the specific structure of the material distribution hopper 1 is not limited in the embodiments of the present invention. In some embodiments, the material distribution hopper 1 is rectangular, and the material distribution pipes 2 adopt the same rectangular structure as the material distribution hopper 1 and are welded into a Y-shaped structure.

[0035] In other embodiments, the material distribution hopper 1 is cylindrical, and the material distribution pipes 2 adopt the same cylindrical structure as the material distribution hopper 1 and are welded into a Y-shaped structure.

[0036] In addition, the shape of the diversion plate 301 is not limited in the embodiments of the present invention. In some embodiments, the diversion plate 301 adopts a shape adapted to the material distribution hopper 1 and the material distribution pipes 2, that is, when both the material distribution hopper 1 and the material distribution pipes 2 are rectangular, the diversion plate 301 is also rectangular.

[0037] In other embodiments, when the material distribution hopper 1 and the material distribution pipes 2 adopt a cylindrical structure, the diversion plate 301 also adopts an arc-shaped structure.

[0038] In addition, the rotation position of the diversion plate 301 is not limited in the embodiments of the present invention.

[0039] In some embodiments, the two diversion plates 301 can be rotatably installed on the material distribution hopper 1 on the side close to each other, and the hinge position is located between the two material distribution pipes 2. Therefore, when the angle of the diversion plate 301 changes, the flow rate of the material distribution pipes 2 can be adjusted.

[0040] In other embodiments, the two diversion plates 301 can be fixed with a rotating shaft 302 in the middle, and the rotating shaft 302 is rotatably installed at the position where the two material distribution pipes 2 are connected to the material distribution hopper 1. Therefore, when the rotating shaft 302 is rotated, the flow rate of the material distribution pipes 2 can be controlled. When the diversion plate 301 rotates to a position parallel to the material distribution pipes 2, the flow rate of the material distribution pipes 2 reaches the maximum.

[0041] During use, the material distribution pipes 2 are fixedly connected and communicated with the material distribution hopper 1, and at the same time, the two diversion plates 301 are installed on the material distribution hopper 1. By controlling the angles of the two diversion plates 301, the material flow rates inside the two material distribution pipes 2 can be controlled, so that the material flow rates in the two material distribution pipes 2 can be adjusted according to the requirements of different positions, meeting different feeding requirements, reducing the overall size and production difficulty of the feeding device, reducing the torque for flipping the diversion plate 301, thereby reducing the production cost. At the same time, it has a faster response and can timely adjust the flow rate of the material diversion, meeting the high-precision requirements for the loading weight.

[0042] Please refer to Figures 1 - 3 , in order to further improve the control of the material flow rate, in some embodiments, two diversion plates 301 are respectively located above the two material distribution pipes 2. Two rotating shafts 302 are rotatably installed on the material hopper 1. One end of each of the two diversion plates 301 is connected to each of the two rotating shafts 302. That is to say, the sides of the two diversion plates 301 away from each other are hinged to the material hopper 1 through the rotating shafts 302. Therefore, when the diversion plates 301 are rotated, the flow rates of the two material distribution pipes 2 can be controlled. And because the change in its inclination angle is small, the adjustment efficiency is high, the torque required for adjustment is smaller, which is beneficial to reducing costs and improving the accuracy of flow rate control.

[0043] Please refer to Figures 1 - 3 , in order to further facilitate the control of the flow rate of the material distribution pipe 2 and at the same time increase the stability of the connection of the material distribution pipe 2, in some embodiments, a partition plate 303 is provided inside the material hopper 1 and is located between the two material distribution pipes 2. When the end of the diversion plate 301 away from the material hopper 1 approaches the partition plate 303, the material distribution pipe 2 on the side where the diversion plate 301 is located is closed. That is to say, the partition plate 303 is located between the two material distribution pipes 2. The partition plate 303 can increase the contact area between the two material distribution pipes 2, thereby increasing the stability after the two material distribution pipes 2 are connected. At the same time, the partition plate 303 can increase the closing effect when the diversion plate 301 blocks the material distribution pipe 2 and reduce the situation of material leakage.

[0044] It should be noted that in the embodiments of the present invention, by changing the shape of the partition plate 303, the purpose of further reducing the torque during the operation of the diversion plate can be achieved. Specifically, the partition plate 303 is configured with a triangular or isosceles trapezoidal cross-section to reduce the distance between the partition plate 303 and the diversion plate 301, thereby reducing the torque required for the diversion plate 301 to rotate.

[0045] In addition, the embodiments of the present invention do not limit the way of controlling the diversion plate 301. In some embodiments, a manual control method can be adopted. For example, before feeding, the partition plate 303 is manually rotated to the corresponding position and then fixed.

[0046] In order to further improve the versatility of the device during use, some control components can be used for control. The diversion assembly 3 further includes a driving member 304. The driving member 304 is installed on the material hopper 1. The driving member 304 is used to control the angle of the diversion plate 301. That is to say, the diversion plate 301 is controlled by the driving member 304 to improve the automation degree of the device during use.

[0047] In some embodiments, the driving member 304 is an electric cylinder. The angle adjustment of the diverter plate 301 is controlled by the telescopic movement of the electric cylinder. That is to say, the angle of the diverter plate 301 is adjusted by the telescopic movement of the electric cylinder. Generally, an electric cylinder with a power of 1.5 kw - 2 kw, a stroke of about 300 mm, a propulsion speed of 166 mm / s, and a thrust greater than 800 kgN is selected. Specifically, the extending end of the electric cylinder is hinged to the diverter plate 301, and the other end of the electric cylinder is hinged to the hopper 1.

[0048] In other embodiments, the driving member 304 is a hydraulic cylinder. The angle adjustment of the diverter plate 301 is controlled by the telescopic movement of the hydraulic cylinder. That is to say, the rotation of the diverter plate 301 is driven by the telescopic movement of the hydraulic cylinder, and thus the diversion control of the material can be achieved. Specifically, the extending end of the hydraulic cylinder is hinged to the diverter plate 301, and the other end of the hydraulic cylinder is hinged to the hopper 1.

[0049] In other embodiments, the driving member 304 is a pneumatic cylinder. The angle adjustment of the diverter plate 301 is controlled by the telescopic movement of the pneumatic cylinder. That is to say, the rotation of the diverter plate 301 is driven by the telescopic movement of the pneumatic cylinder, and thus the diversion control of the material can be achieved. Specifically, the extending end of the pneumatic cylinder is hinged to the diverter plate 301, and the other end of the pneumatic cylinder is hinged to the hopper 1.

[0050] It should be noted that in the embodiments of the present invention, the installation position of the driving member 304 is not limited. The driving member 304 can be arranged on the outer wall of the hopper 1 through a bracket, or can be arranged on other structures not connected to the hopper 1.

[0051] When the driving member 304 is arranged inside the hopper 1, in some embodiments, an installation bracket 305 is provided on the hopper 1, and a through hole is provided on the hopper 1. One end of the driving member 304 is hinged to the installation bracket 305, and the other end of the driving member 304 passes through the through hole and is hinged to the diverter plate 301. That is to say, a through hole is opened on the hopper 1 for the driving member 304 to extend into the hopper 1 and be hinged to the diverter plate 301, so as to control the diverter plate 301, which is beneficial to improving the control effect of the diverter plate 301 and further reducing the torque when the diverter plate 301 rotates.

[0052] It should be noted that in the embodiments of the present invention, the through hole is a strip-shaped structure with the same movement track as the driving member 304.

[0053] In addition, in some embodiments, a sealing plate made of rubber can be installed at the through hole, and the sealing plate can reduce the situation of material falling from the through hole.

[0054] In addition, in some embodiments, in order to further reduce the torque during the movement of the drive diverter plate 301, the hinge joint between the drive member 304 and the diverter plate 301 is located on the side of the diverter plate 301 away from the hopper 1. That is to say, by changing the position where the drive member 304 is hinged to the diverter plate 301, the purpose of reducing the torque is achieved.

[0055] In order to further adapt to the situation where a larger torque is required, in some embodiments, the drive member 304 is a motor screw structure. An articulated bearing connecting rod is installed on the screw. The screw and the diverter plate are hinged and connected through the articulated bearing connecting rod. The motor drives the screw to rotate to adjust the angle of the diverter plate 301. Specifically, the motor is installed outside the hopper 1. The motor drives the screw to rotate. The screw and the diverter plate 301 are hinged with an articulated bearing connecting rod. In this way, when the motor drives the screw to rotate, it pushes the articulated bearing connecting rod to move, realizing the adjustment of the angle of the diverter plate 301. Utilizing the locking ability of the screw can greatly reduce the influence of the torque on the motor and improve the service life of the motor.

[0056] In order to further adapt to the situation where a larger torque is required, in some other embodiments, the drive member 304 is a motor, a worm gear is installed on the rotating shaft 302, and a worm that cooperates with the worm gear is installed at the output end of the motor. That is to say, through the cooperation of the worm and the worm gear, the output torque of the motor is enhanced to meet the situation where a larger torque is required during use.

[0057] It should be noted that in the embodiments of the present invention, in order to further reduce the material from falling through the through hole to the outside, in some embodiments, two inclined guard plates are installed on the hopper 1 and are located above the two rotating shafts 302 to prevent the material from falling between the rotating shaft 302 and the side wall of the hopper 1, thereby avoiding the material from falling out through the through hole.

[0058] That is to say, the key point of the embodiments of the present invention is: during use, the distribution pipe 2 is fixedly connected and communicated with the hopper 1, and at the same time, the two diverter plates 301 are installed on the hopper 1. By controlling the angles of the two diverter plates 301, the material flow rates inside the two distribution pipes 2 can be controlled, so that the material flow rates in the two distribution pipes 2 can be adjusted according to the requirements of different positions, meeting different feeding requirements, reducing the overall size and production difficulty of the feeding device, reducing the torque for flipping the diverter plate 301, thereby reducing the production cost, and at the same time having a faster response and being able to timely adjust the flow rate of the material diversion to meet the high-precision requirements for the loading weight.
