Description

Technical Field

[0001] The utility model belongs to the technical field of flour processing, and particularly relates to a feeding device for a flour mill. Background Art

[0002] A flour mill is a wheat processing machine that relies on external power to grind wheat into small particles and separates flour particles of different sizes by adjusting the size of the sieve holes to obtain flour small particles; when using a flour mill for flour-making operations, due to the limitations of the internal capacity of the flour mill and the size of the feeding port, a feeding device needs to be used for feeding to ensure continuous grinding operations of the flour mill.

[0003] In a Chinese patent with the publication number CN208944340U, a feeding device for a flour mill is disclosed. A spiral stirring paddle is driven to rotate by a first rotating motor to prevent flour raw materials from accumulating in the feeding box body and blocking the discharge pipe. At the same time, a second hydraulic cylinder is driven to rotate by a second rotating motor, and the telescoping of the second hydraulic cylinder can further prevent the discharge pipe from being blocked, achieving a very effective anti-blocking effect.

[0004] The feeding device is set to continuously feed the flour mill. However, the discharge pipe orifice of the above device is arranged at the bottom of the device, while its feeding pipe is arranged above the device. Moreover, the discharge port of the feeding device also needs to be arranged above the feeding port of the flour mill, making the height of the feeding pipe of this device relatively high and the difficulty of adding wheat to the feeding device relatively large. Therefore, a feeding device for a flour mill is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a feeding device for a flour mill to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A feeding device for a flour mill, comprising:

[0008] A feed box, the top of the feed box is provided with a feed inlet, and one end of the feed inlet is hingedly installed with a flip cover;

[0009] A material conveying cylinder, the material conveying cylinder is fixedly connected to one side surface of the feed box, and one side of its top is fixedly connected with a discharge pipe communicated with its interior;

[0010] A material conveying through port, which is used to communicate the interiors of the feed box and the material conveying cylinder;

[0011] A spiral material conveying shaft, which is rotatably installed inside the material conveying cylinder and is used to convey the wheat entering the interior of the material conveying cylinder upward;

[0012] Anti-stagnation mechanism, the anti-stagnation mechanism is installed inside the feed bin to prevent wheat from caking and stopping flowing inside the feed bin.

[0013] Preferably, a servo motor is fixedly installed at the upper end of the feeding cylinder, and the driving end of the servo motor is fixedly connected to the screw feeding shaft.

[0014] Preferably, the inside of the feed bin is set as a triangular prism-shaped cavity with an inclined bottom surface, and the feeding port is arranged at the lowest end inside the feed bin.

All the rotating shafts are rotatably connected to the two side walls of the feed bin and are parallel to each other. All the stirring blades are arranged at the inner bottom of the feed bin and are respectively fixedly connected to one of the rotating shafts. The adjacent two rotating shafts are driven by the belt pulleys. The control motor is fixedly installed on one side outer wall of the feed bin, and its driving end is fixedly connected to one of the rotating shafts.

[0016] Preferably, an observation window is arranged on the side of the feed bin.

[0017] Preferably, rollers are installed at the bottoms of the feed bin and the feeding cylinder.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] (1) By setting the feed bin, the feeding cylinder and the screw feeding shaft, the present utility model can convey the wheat stored in the feed bin to a high place. The feeding port of the feed bin is arranged at a relatively low position, which is convenient for pouring wheat into the device, and the feeding speed can also be controlled by changing the rotation speed of the screw feeding shaft.

[0020] (2) By setting the anti-stagnation mechanism, the present utility model can prevent wheat from stopping flowing inside the feed bin, resulting in the wheat not being able to enter the inside of the feeding cylinder through the feeding port, so that when the wheat inside the feeding device is not used up, the wheat can be output stably and continuously.

[0027] Embodiment:

[0028] Refer to Figure 1 、 Figure 2 and Figure 3 As shown, a feeding device for a flour mill includes:

[0029] A feed bin 1, with a feed inlet opened at the top of the feed bin 1, and one end of the feed inlet is hingedly installed with a flap 11;

[0030] A feeding tube 2, the feeding tube 2 is fixedly connected to one side of the feed bin 1, and a discharge pipe 21 communicating with its interior is fixedly connected to one side of its top;

[0031] A feeding port 3, the feeding port 3 is used to communicate the interiors of the feed bin 1 and the feeding tube 2;

[0032] A screw conveyor shaft 4, the screw conveyor shaft 4 is rotatably installed inside the feeding tube 2 for conveying the wheat entering the interior of the feeding tube 2 upward;

[0033] An anti-stagnation mechanism 5, the anti-stagnation mechanism 5 is installed inside the feed bin 1 to prevent the wheat from caking and stopping flowing inside the feed bin 1.

[0034] As can be seen from the above, by setting the feed bin 1, the feeding tube 2 and the screw conveyor shaft 4, the wheat stored in the feed bin 1 can be input into the feeding tube 2 through the feeding port 3 and conveyed to a high place by the screw conveyor shaft 4. The feed inlet of the feed bin 1 is set at a relatively low position, which is convenient for pouring wheat into the feeding device of the flour mill, and the feeding speed can also be controlled by changing the rotation speed of the screw conveyor shaft 4.

[0035] Specifically, as can be seen from Figure 3 , a servo motor 6 is fixedly installed at the upper end of the feeding tube 2, and the driving end of the servo motor 6 is fixedly connected to the screw conveyor shaft 4.

[0036] As can be seen from the above, the servo motor 6 can change the rotation speed of the spiral feeding shaft 4, so that the feeding speed is controllable.

[0037] Specifically, it can be seen from Figure 3 that the inside of the feed bin 1 is provided with a triangular prism-shaped cavity with an inclined bottom surface, and the feeding opening 3 is arranged at the bottommost end inside the feed bin 1.

[0038] As can be seen from the above, under the action of gravity, the wheat will naturally slide towards the direction of the feeding opening 3 and fall into the inside of the feeding cylinder 2.

[0039] Specifically, it can be seen from Figure 2 and Figure 3 that the anti-stagnation mechanism 5 includes a rotating shaft 51, stirring blades 52, belt pulleys 53 and a control motor 54. All the rotating shafts 51 are rotatably connected to the two side walls of the feed bin 1 and are parallel to each other. All the stirring blades 52 are arranged at the inner bottom of the feed bin 1 and are respectively fixedly connected to one of the rotating shafts 51. The adjacent two rotating shafts 51 are driven by the belt pulleys 53. The control motor 54 is fixedly installed on the outer wall of one side of the feed bin 1, and its driving end is fixedly connected to one of the rotating shafts 51.

[0040] As can be seen from the above, since all the stirring blades 52 are arranged at the inner bottom of the feed bin 1, when the rotating shaft 51 rotates, the stirring blades 52 can extrude and push the wheat at the bottom of the feed bin 1, so that the stagnant wheat moves downward, avoiding the wheat from caking and no longer flowing, and keeping the feeding speed stable.

[0041] Specifically, it can be seen from Figure 1 that an observation window 7 is arranged on the side of the feed bin 1.

[0042] As can be seen from the above, by setting the observation window 7, the remaining amount of wheat inside the feed bin 1 can be monitored.

[0043] Specifically, it can be seen from Figure 1 that rollers 8 are installed at the bottoms of both the feed bin 1 and the feeding cylinder 2.

[0044] As can be seen from the above, by setting the rollers 8, it is convenient to move the device, so that the device can load and output wheat in different places.
