Description

Technical Field

[0001] This utility model relates to the field of metering bin technology, specifically to a self-feeding powder metering bin. Background Technology

[0002] A metering bin is a measuring instrument that conforms to nationally unified standards. By placing materials into the metering bin, materials can be unloaded in a quantitative manner. Metering bins are also containers used for medium-volume transportation and storage. This equipment is widely used in solid granular materials in industries such as chemical, petroleum, and fertilizer. It is also suitable for unloading, storage, and metering in the production process of powders and powder-granular mixtures.

[0003] In order to slow down the material flow and prevent the material from being completely spilled out during the feeding process, most existing metering silos are usually designed with a conical opening at the bottom. This allows the material to flow out slowly when the feeding port is opened. However, if the feeding port is too small or narrow, the powder may get stuck at the outlet or stagnate at the feeding port, causing the feeding to stop. Utility Model Content

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figures 1-6 As shown in the figure, this embodiment proposes a self-feeding powder metering bin, including a support frame 1, a bin body 2, a pushing component, a baffle plate 3, a support component, and a clearing component. Two support frames 1 are provided, and the sides of the two support frames 1 are provided with sliding grooves. The bin body 2 is fixedly installed between the two support frames 1, and the top of the bin body 2 is provided with a feed inlet. Two pushing components are provided, and the two pushing components are respectively provided on both sides of the bin body 2. Two baffle plates 3 are provided, and the two baffle plates 3 are respectively provided on the two pushing components. Two support components are provided, and the two support components are respectively provided on the sides of the two support frames 1 for supporting the baffle plates 3. The clearing component is provided on the support frame 1 for clearing the powder. By pushing the two baffle plates 3, the two baffle plates 3 can be pushed away from each other to form an opening, allowing the powder to flow out. The powder in the bin body 2 can also be conveyed by the conveying component. If the powder forms a blockage when flowing out, the clearing component can clear the powder at the opening.

[0030] In this embodiment, reference Figure 2 The pushing assembly includes a mounting plate 101, a cylinder 102, and a pushing frame 103. The mounting plate 101 is fixedly installed on the side of the hopper 2. The cylinder 102 is installed on the mounting plate 101. The pushing frame 103 is fixedly connected to the output end of the cylinder 102 and is also fixedly connected to the side of the baffle plate 3. By activating the cylinder 102, the cylinder 102 drives the pushing frame 103 to move, thereby causing the two baffle plates 3 to move to opposite positions, forming an opening and allowing the powder to flow out.

[0031] In this embodiment, reference Figure 3 The support assembly includes a mounting frame 201, a sliding rod 202, and a support plate 203. The mounting frame 201 is fixedly installed on the side of the support frame 1, and the sliding rod 202 is fixedly installed on the mounting frame 201. There are two support plates 203, which are slidably installed on the sliding rod 202. The two support plates 203 are respectively fixedly connected to the sides of the two baffle plates 3. When the baffle plate 3 moves, it can drive the support plate 203 to move synchronously on the sliding rod 202, thereby supporting the baffle plate 3 and preventing the baffle plate 3 from tilting due to the downward pressure of powder.

[0032] In this embodiment, reference Figure 4The unblocking assembly includes a sliding rod 301, a support cover 302, a reciprocating screw 303, a screw nut 304, an unblocking rod 305, and a motor 306. Two sliding rods 301 are provided, each slidably installed in a groove within one of the two support frames 1. The support cover 302 is fixedly installed between the two sliding rods 301. The reciprocating screw 303 is rotatably installed within the support cover 302. The screw nut 304 is threadedly connected to the reciprocating screw 303. The unblocking rod 305 is fixedly installed on the screw nut 304. The motor 306 is installed on the side of the support cover 302, and its output end is fixedly connected to the reciprocating screw 303. When the motor 306 is started, it drives the reciprocating screw 303 to rotate, causing the screw nut 304 to move on the reciprocating screw 303. This causes the unblocking rod 305 to reciprocate at the opening between the two baffle plates 3, unblocking the powder and preventing blockage.

[0033] In this embodiment, the unblocking assembly also includes a fixing plate 401 and a second cylinder 402. The fixing plate 401 is fixedly installed between two support frames 1. The second cylinder 402 is installed on the fixing plate 401, and the output end of the second cylinder 402 is fixedly connected to the bottom end of the support cover 302. When the second cylinder 402 is activated, the second cylinder 402 pushes the support cover 302 to move up and down, thereby allowing the unblocking rod 305 to be inserted into the chamber 2 to unblock the powder.

[0034] In this embodiment, reference Figure 5 It also includes a positioning component, which includes a positioning plate 501, a positioning rod 502, and a bolt 503. The positioning plate 501 is fixedly installed at the bottom of the support frame 1, and the side of the positioning plate 501 has several threaded holes. Several positioning rods 502 are provided and are slidably installed on the positioning plate 501. The side of the positioning rod 502 has several threaded holes, and the bolt 503 is threadedly connected to the threaded holes. By moving the positioning rod 502, the distance that the baffle plate 3 moves is adjusted by blocking the support plate 203 through the positioning rod 502, thereby adjusting the size of the material discharge opening.

[0035] In this embodiment, reference Figure 6 It also includes a conveying assembly, which includes a second motor 601, a conveying shaft 602, and a conveying plate 603. The second motor 601 is installed at the top of the silo body 2, the conveying shaft 602 is located inside the silo body 2, and the conveying shaft 602 is fixedly connected to the output end of the second motor 601. The conveying plate 603 is fixedly installed on the conveying shaft 602. When the second motor 601 is started, the second motor 601 drives the conveying shaft 602 to rotate, and the conveying shaft 602 drives the conveying plate 603 to rotate, thereby conveying the powder in the silo body 2 down.

[0036] In this embodiment, reference Figure 2 and Figure 4The top of the unblocking rod 305 is located in the middle of the two baffle plates 3, so that the unblocking rod 305 can be inserted into the opening between the two baffle plates 3.

[0037] In this embodiment, reference Figure 3 and Figure 5 The support plate 203 has a semi-circular groove on its side, and the positioning rod 502 can be inserted into the semi-circular groove. When the support plate 203 moves to the positioning rod 502, the positioning rod 502 is inserted into the semi-circular groove of the support plate 203, thereby blocking it.

[0038] In this embodiment, reference Figure 1 A feed cylinder 4 is fixedly installed at the feed inlet of the silo body 2, through which powder can be placed into the silo body 2.

[0039] In this embodiment, when the metering chamber is discharging material, cylinder 102 is first activated. Cylinder 102 drives the pusher 103 to move, and the pusher 103 drives the two baffle plates 3 to move in opposite directions, thereby forming an opening between the two baffle plates 3 to allow powder to flow out. The size of the opening can be controlled by sliding the positioning rods 502 at different positions according to the flow rate or amount. The corresponding positioning rods 502 can be slid downwards, and then bolts 503 are threaded into the threaded holes of the positioning rods 502 and the positioning plates 501. When the baffle plates 3 drive the support plate 203 to move, the support plate 203 can be blocked by the positioning rods 502, thereby restricting the baffle plates 3 from moving further. The size of the opening is fixed. When the powder flows out, motor 2 601 can be started. Motor 2 drives the conveyor shaft 602 to rotate, and the conveyor shaft 602 drives the conveyor plate 603 to rotate, thereby conveying the powder in the silo 2 down. If the powder is blocked at the opening, cylinder 2 402 can be started. Cylinder 2 402 pushes the support cover 302 upward, so that the unblocking rod 305 is inserted into the opening. Then motor 1 306 is started. Motor 1 306 drives the reciprocating screw 303 to rotate. The screw nut 304 moves on the reciprocating screw 303, thereby driving the unblocking rod 305 to move back and forth at the opening between the two baffle plates 3, stirring and unblocking the powder so that it can flow out smoothly.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
