[0002] There are various feeders generally used for bulk material conveying, such as vibrating feeders, disc feeders, belt feeders, rotary feeders, star feeders, reciprocating feeders, etc. The structures of existing feeders are complex, difficult to maintain, unreliable in operation, and have a narrow applicable range.

[0003] When the material in the silo stops discharging, an additional baffle mechanism composed of a bunker plate or a baffle plate is required to close the feeding port of the silo, which makes the closing operation of the silo troublesome and inconvenient. Summary of the Utility Model

[0005] To achieve the above object, the technical solution provided by the utility model is as follows:

[0006] The utility model provides a feeding device with self-locking function, which includes a silo with a feeding port. The silo is filled with materials with low fluidity, and further includes a feeding mechanism. The feeding mechanism has a closed discharging cavity and a feeding port and a discharging port communicating with the discharging cavity. The feeding port is located above the discharging port, and the feeding port is connected to the feeding port. A feeding blade group is arranged in the discharging cavity. The feeding blade group includes at least two coaxially fixed feeding blades. The included angle between two adjacent feeding blades is at least 90 degrees, and a baffle switch is formed. The feeding blades and the inner wall of the discharging cavity are arranged with a gap. The feeding blades are arranged to be rotatable at a fixed point, so that the baffle switch switches between the self-locking position for closing the feeding port and the open position for opening the feeding port.

[0007] Further, the feeding blade group further includes a rotating shaft, and the feeding blades are respectively fixed on the corresponding rotating shafts.

[0008] Further, the number of the feeding blade groups is two, and the rotating shafts of the two feeding blade groups are arranged to rotate synchronously or independently.

[0009] Further, when the feeding port is closed, one of the baffle switches of the two baffle blade groups has the baffle blades abutting against each other and rotating to the same plane with a gap therebetween, and at the same time, the other baffle blades of the two baffle switches open outwards respectively.

[0010] Further, the central lines of the feeding port and the discharging port coincide; the axial central lines of the two rotating shafts are parallel to the ground and on the same horizontal plane; the central line of the blanking port is perpendicular to the ground, and the axial central lines of the two rotating shafts are symmetrically distributed on both sides of the central line of the feeding port.

[0011] Further, the baffle blade group includes a driver, and the driver is drivingly connected to the baffle blade to drive the baffle blade to rotate at a fixed point.

[0023] To further illustrate the embodiments, the present utility model provides accompanying drawings. These accompanying drawings are a part of the disclosure of the present utility model, mainly used to illustrate the embodiments, and can be combined with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0025] Referring to Figure 1 and Figure 2 As shown, this embodiment provides a self-locking feeding device (hereinafter simply referred to as the feeding device) for bottom discharging of various bins. The feeding device includes a bin 2 having a discharging port 21, and the bin 2 is filled with materials 1 with low fluidity. The feeding device further includes a feeding mechanism 3. The feeding mechanism 3 has a closed discharging chamber 34 and a feeding port 38 and a discharging port 37 communicating with the discharging chamber 34. The feeding port 38 is located above the discharging port 37. The discharging port 21 vertically extends into the feeding port 38 of the discharging chamber 34, and the bottom of the bin 2 is tightly abutted against the outer wall of the discharging chamber 34. A receiving unit 4 for receiving the materials 1 output from the feeding mechanism 3 is placed at the discharging port 37. The receiving unit 4 adopts a belt conveyor, a belt scale or a disk feeder in the prior art, etc.

[0026] Two groups of material deflecting blade groups 31 are arranged in the discharging chamber 34. Each material deflecting blade group 31 includes two coaxially fixed material deflecting blades. The included angle between two adjacent material deflecting blades in the same group is at least 90 degrees, and a material blocking switch is formed. And the material deflecting blades and the inner wall of the discharging chamber 34 are arranged with a gap to ensure that when the material deflecting blades rotate in the discharging chamber 34, the materials 1 in the bin 2 will not leak through the gap between the material deflecting blades and the inner wall of the discharging chamber 34.

[0027] The material deflecting blades are rotatably arranged at a fixed point, so that the material blocking switch can be switched between a self-locking position for closing the feeding port 38 as shown in Figure 1 and an open position for opening the feeding port 38 as shown in Figure 2 as shown.

[0028] In this embodiment, the material 1 with low fluidity cannot pass through the gaps in the feeding device, that is, the material 1 with low fluidity is blocked by the gap structure and cannot leak.

[0029] The feeding mechanism 3 is provided with a fixed bracket, which includes a vertical bracket 36 fixed on the ground 5 and a cross beam 33 connected to the upper end of the vertical bracket 36. The feeding mechanism 3 is assembled on the cross beam 33 and is suspended, so as to be installed and fixed on the ground 5. At the same time, it is convenient to install the receiving unit 4 on the feeding mechanism 3, and the load can be transmitted to the ground 5.

[0030] The material distributing blade group 31 further includes a rotating shaft 32. The material distributing blades are respectively fixed on the corresponding rotating shafts 32. The central lines of the feeding port 38 and the discharging port 37 coincide. The axial central lines of the two rotating shafts 32 are parallel to the ground 5 and on the same horizontal plane. The central line of the discharging port 21 is perpendicular to the ground 5, and the axial central lines of the two rotating shafts 32 are symmetrically distributed on both sides of the central line of the feeding port 38, so as to ensure that one of the material distributing blades of the material blocking switches of the two material distributing blade groups 31 abuts against each other and rotates to the same plane, while the other material distributing blades of the two material blocking switches open outwards respectively. At this time, the feeding port 38 is closed by the two material blocking switches to prevent the material 1 in the storage bin 2 from flowing to the discharging port 37.

[0031] As Figure 3 shown, when the rotating shafts 32 of the two material distributing blade groups 31 are set to rotate synchronously, the material distributing blade group 31 includes one driver. The same driver drives the two rotating shafts 32 to rotate synchronously through transmission units such as gear sets, so as to drive all the material distributing blades to rotate synchronously, so as to realize that the material distributing blades can rotate at a fixed point, that is, the material distributing blades of the two material distributing blade groups 31 can rotate synchronously to the rotation angle as Figure 1 shown, so that the material 1 in the storage bin 2 remains stable and static, and the material 1 will not flow to the receiving unit 4 by itself.

[0032] As Figure 4 shown, when the rotating shafts 32 of the two material distributing blade groups 31 are set to rotate independently, the material distributing blade group 31 includes two independent drivers. The two drivers respectively drive the two rotating shafts 32 to rotate or not rotate, so as to drive the material distributing blades of the corresponding material blocking switches to rotate accordingly, so as to realize that the material distributing blades of the corresponding material blocking switches can rotate at a fixed point, that is, the material distributing blades of the material blocking switch of one of the material distributing blade groups 31 can rotate to the rotation angle as Figure 1 shown, and cooperate with the material blocking switch of the other material distributing blade group 31, so that the material 1 in the storage bin 2 remains stable and static, and the material 1 will not flow to the receiving unit 4 by itself. Of course, starting one rotating shaft 32 or two rotating shafts 32 at the same time, or setting different rotation speeds and directions for the two rotating shafts 32 can also realize different feeding modes.

[0033] The specific driver is a motor, which adjusts the speed of the corresponding rotating shaft 32 by controlling the speed of the motor, thereby controlling the material-pickup speed of the material-pickup blade on the rotating shaft 32, so as to more easily control the feeding amount. The driving shaft of the motor can also stop rotating, and the material-pickup blade on the rotating shaft 32 will also rotate to the same position as above. Figure 1 The rotation angle shown is then maintained to achieve the stop self-locking function.

[0034] By setting the material-discharging blade to be rotatable at a fixed point, the material-blocking switch can be switched between a self-locking position for closing the feed port 38 and an open position for opening the feed port 38. In this way, active feeding can be achieved, that is, the material 1 is moved in the feeding direction from the feed port 38 toward the discharge port 37 to change the flow speed of the material 1 in the feeding mechanism 3, thereby being suitable for the transportation of materials 1 with low fluidity and making it easier to achieve precise control of the feeding amount.

[0035] When the unloading is stopped, the unloading port 21 of the material storage 2 can be blocked by the shutdown self-locking without setting up other material blocking mechanisms.

[0036] In addition, the entire feeding device has a simple structure, is easy to maintain, operates reliably, occupies a small space, can also realize closed feeding operation to meet environmental protection requirements, and has low overall energy consumption.

[0037] Of course, in other embodiments, the discharge port 21 may also be connected to the feed port 38 via a delivery pipe, and closed delivery may also be achieved.

[0038] According to the different fluidity and shapes of the materials 1, one or more than three material-dispensing blades may be arranged on the same rotating shaft 32, and the more than three material-dispensing blades on the same rotating shaft 32 may be evenly distributed or unevenly distributed.

[0039] In addition, when the number of material-moving blade groups 31 is one, the material-moving blade group 31 is set on one side of the feed port 38, and the material-moving blade group 31 on the other side is replaced by a fixed L-shaped material baffle plate to prevent the material 1 from flowing out from the direction of the L-shaped material baffle plate, and at least one material baffle switch is used to close or open the outlet on one side of the feed port 38 away from the L-shaped material baffle plate. Therefore, by turning the material baffle switch, the feed port 38 can also be closed or opened.

[0040] In another preferred embodiment, a transversely fixed material support plate 35 is provided in the discharge chamber 34, the material support plate 35 is arranged below the material-discharging blade group 31, and the material support plate 35 corresponds to the feed port 38. When the feed port 38 is fully opened,

[0041] The material 1 falling from above is blocked by the material support plate 35 to disperse the flow direction of the material 1 and delay the downward flow rate of the material 1, so as to ensure that the pressure formed by the falling of the material 1 will not act entirely on the receiving unit 4 located below the feeding mechanism 3, thereby ensuring that the receiving unit 4 is not crushed.

[0042] Although the present invention is specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them fall within the protection scope of the present invention.
