[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] Example

[0027] like Figure 1 、 2 As shown in Figure 3, the granular material flow controller of this embodiment includes a shell 1, a rotary material receiving component 2 and a driving device 3. The top of the shell 1 is provided with a feed port, and the bottom is provided with a discharge port. The feed port is provided with a discharge channel 4. The rotary material receiving component 2 is rotatably installed in the shell 1. The driving device 3 is installed at the side end of the shell 1 and is connected with the rotary material receiving component 2 for driving the rotary material receiving component 2 to rotate in the shell 1. The rotary material receiving component 2 is provided with a plurality of material receiving troughs along its rotation circumference, and the material receiving troughs are in contact with or close to the inner wall of the shell 1. During the rotation of the rotary material receiving component 2, the material receiving troughs pass through the bottom of the feed port and the top of the discharge port one by one. A detector 5 for detecting whether material is discharged inside is provided on the side wall of one side of the discharge channel 4.

[0028] During use of the granular material flow controller of this embodiment, the feed port at the top of the shell 1 is connected to the incoming material pipe, and the discharge port at the bottom is connected to the unloading material pipe. At the same time, the driving device 3 drives the rotary material receiving component 2 to rotate, so that multiple material receiving troughs distributed circumferentially on its surface pass under the feed port in sequence (clockwise or counterclockwise rotation). During a period of time, the rice in the feed port falls into the material receiving trough passing below. As the material receiving trough rotates through the feed port, the rice falls into the subsequent material receiving troughs in sequence. When the driving device 3 drives the rotary material receiving component 2 to rotate at a uniform speed at an adapted speed, each material receiving trough can receive a similar or identical amount of rice. During the continuous rotation of the material receiving trough, the rice will fall through the discharge port at the bottom of the shell 1 under gravity as the material receiving trough rotates downward, thereby realizing the intermittent same (or similar) flow rate of rice falling. The discharge flow rate can be adjusted by adjusting the speed at which the driving device 3 drives the rotary material receiving component 2 to rotate. The overall structural design is reasonable and ingenious. Through the rotation of the rotary receiving assembly, each receiving trough can receive and discharge the material evenly, thereby achieving uniform flow discharge of grain.

[0029] It should be noted that during the rotation of the material receiving assembly 2, the opening of the material receiving trough is close to the inner wall of the shell 1, and the gap between the two will not contain rice, that is, rice will not flow through the gap between the two.

[0030] In this embodiment, the above-mentioned shell 1 adopts a horizontally arranged cylindrical shell, and the inner cavity of the shell 1 is a cylindrical cavity. A feed port is set at the top (middle) of the inner cavity, and the width of the feed port is consistent with the width of the material receiving trough. A discharge port is set in the middle of the bottom, and the width of the discharge port is also consistent with the width of the material receiving trough.

[0031] As a preferred embodiment, Figure 3 、 4 As shown, the rotary material receiving assembly 2 includes a rotating drum 21, a circular first end plate 22 and a circular second end plate 23. The rotating drum 21 is coaxially arranged in the shell 1, and the first end plate 22 and the second end plate 23 are coaxially fixed to the two ends of the rotating drum 21 respectively. The first end plate 22 and / or the second end plate 23 are rotatably connected to the side walls of the shell 1 through a short shaft. The outer surface of the rotating drum 21 is provided with a plurality of partition plates 24 at equal intervals along the circumferential direction. The partition plates 24 extend along the radial direction of the rotating drum 21, and the two ends thereof are vertically connected to the first end plate 22 and the second end plate 23 respectively. The material receiving trough is defined between the two adjacent partition plates 24, and the outer side of the partition plate 24 is in contact with or close to the inner wall of the shell 1.

[0032] In the above embodiment, the outer diameter of the first end plate 22 and the second end plate 23 are consistent with the inner diameter of the cylindrical cavity inside the shell 1, and the two are almost in contact. Therefore, the gap between the two will not contain rice. That is to say, during the rotation of the receiving chute, when it completely passes the feed port at the top of the shell 1 but has not yet reached the discharge port, the rice will be confined in the "closed" cavity formed between the receiving chute and the side wall of the shell 1. When the drum 21 is driven to rotate by the driving device 3, each receiving chute can achieve the purpose of receiving and unloading materials in a clockwise or counterclockwise rotation.

[0033] As a preferred embodiment, the above-mentioned feed port is a square cylinder, and the upper edge is surrounded by a lower side plate, the lower edge of the above-mentioned discharge channel 4 is surrounded by an upper side plate, the above-mentioned lower side plate is fitted with the upper side plate and connected by bolts, and the above-mentioned discharge port is a square cylinder, and its lower edge is provided with a mounting plate.

[0034] In the above embodiment, the square cylindrical structure of the feed port matches the shape of the receiving trough and facilitates the assembly and detection of the detector. At the same time, the design of the lower and upper side plates facilitates the smooth assembly and docking between the discharge channel 4 and the feed port. The design of the mounting plate of the discharge port facilitates the docking with the discharge pipeline.

[0035] As a preferred embodiment, the cross section of the above-mentioned feeding channel 4 is square, the upper end of which is circular and narrowed, and is connected to a cylindrical pipe docking portion 41.

[0036] In the above embodiment, the shape of the material discharge channel 4 is designed so that its upper end can be connected to the incoming material pipeline through the tubular pipeline connection portion 41 .

[0037] In this embodiment, an observation window is provided on one side wall of the material discharge channel 4, and the detector 5 is mounted on the side wall. The observation window can facilitate real-time observation of the material discharge situation.

[0038] As a preferred embodiment, a slit is provided on the other side wall of the above-mentioned discharge channel 4, and a gate plate 6 is horizontally inserted in the above-mentioned slit. The above-mentioned gate plate 6 is used to be pushed inward into the above-mentioned discharge channel 4 to block the discharge, or pulled outward to open it.

[0039] In the above embodiment, the design of the gate 6 facilitates timely interruption of material discharge from the discharge channel 4 or opening thereof. At the same time, its operation adopts a horizontal push-pull method, which is relatively simple and quick.

[0040] In this embodiment, a horizontal support plate 61 is provided on the other side wall of the discharge channel 4, and the gate plate 6 is slidably assembled with the support plate 61. The design of the support plate 61 facilitates the smooth sliding assembly of the gate plate 6.

[0041] In this embodiment, the detector 5 is a photoelectric sensor, and the detector 5 and the drive device 3 are respectively connected to a controller. The detector 5 can detect whether material is falling from the material discharge channel 4. If material is not falling, the controller will immediately control the drive device 3 to stop running, so that the rotary material receiving assembly 2 no longer rotates.

[0042] In this embodiment, the driving device 3 adopts a reduction motor of an adapted model.
