Description

Technical Field

[0001] This utility model relates to the field of feeding equipment, and in particular to a bulk feeding device. Background Technology

[0002] Bulk materials refer to large quantities of unpackaged, blocky, granular, or powdery materials piled together, such as coal, sand, and grains. Currently, most bulk materials are transported by conveyors.

[0003] For example, patent document CN218344703U discloses a bulk material feeding device, including a cylinder. A third valve seat is fixedly connected to one side of the outer wall of the cylinder, and a bulk material conveying device is fixedly connected to the side of the third valve seat away from the cylinder. A feeding cylinder cover is fixedly connected to the upper end of the cylinder, and a bearing seat is fixedly connected to the middle of the feeding cylinder cover. In this utility model, a cylinder seat is connected to a first valve seat to control the opening and closing of the valve. When the first level gauge detects that the amount of material has reached the set value, the bulk material conveying device stops conveying, the third valve seat closes, and a vacuum system connected to the external vacuum flange evacuates the cylinder to a vacuum. The cylinder seat then opens the valve, and the material falls into the valve body connector. The first valve seat closes, and the bulk material conveying device continues to feed. A second level gauge is installed in the second valve seat. When the detected material has fallen completely, the cylinder seat of the second valve seat opens the valve, allowing the bulk material to fall into the electron beam melting furnace.

[0004] In the above-mentioned device, the material feeding is precisely controlled by setting up a bulk material weighing mechanism near the smelting furnace. However, due to the high temperature and dust in the working environment near the smelting furnace, the service life of electronic components is reduced, and the above-mentioned device needs to be maintained frequently. To avoid such a situation, another bulk material feeding device that can precisely control the feeding is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a bulk feeding device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A bulk material feeding device includes a conveyor belt mechanism, which includes a conveyor belt with several uniformly arranged baffles fixedly connected to it.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1-9As shown, a bulk material feeding device includes a conveyor belt mechanism, which includes a conveyor belt 104. A plurality of evenly arranged baffles 103 are fixedly connected to the conveyor belt 104. A closed outer shell 102 covering the baffles 103 is provided outside the conveyor belt 104. A material distribution mechanism is provided on the front side of the closed outer shell 102. The material distribution mechanism includes a material distribution bin 201. A feeding hopper 204 is fixedly connected to one side of the bottom of the material distribution bin 201. The other end of the feeding hopper 204 is fixedly connected to the closed outer shell 102. A material distribution turntable 202 is rotatably connected inside the material distribution bin 201. A plurality of evenly arranged circular baffles are provided on the material distribution turntable 202. The distribution hopper 201 has a through channel, and an electronic scale assembly 203 is fixedly connected to the other side of its bottom. A feeding hopper 204 is symmetrically arranged with the electronic scale assembly 203. A storage hopper 205 is fixedly connected to the top of the distribution hopper 201, with its lower end corresponding to the electronic scale assembly 203. A valve assembly is located at the lower end of the storage hopper 205. A power mechanism for driving the conveyor belt mechanism and the distribution turntable 202 is located at the bottom of the distribution hopper 201. A discharge port 106 is fixedly connected to the bottom rear side of the enclosed housing 102, and a striking mechanism is located above the discharge port 106. The valve assembly includes components connected to the storage hopper 205. A valve motor 207 is fixedly connected to the lower end of the hopper 205. A valve plate 206 is fixedly connected to the output end of the valve motor 207. The valve plate 206 is rotatably connected to the lower end of the hopper 205. The valve plate 206 can close the lower end of the hopper 205. When an external device pours bulk raw materials into the hopper 205, the valve motor 207 drives the valve plate 206 to rotate. When the valve plate 206 opens, the bulk raw materials in the hopper 205 fall into the through groove on the distribution turntable 202. The electronic scale assembly 203 can weigh the weight of the poured bulk raw materials. After reaching the preset weight, the valve motor 207 drives the valve plate 206 to close, and at the same time, the distribution turntable... 202 rotates at a certain angle to rotate the empty channel to directly above the electronic scale assembly 203. The channel on the other side, which is filled with bulk raw materials, passes through the feeding hopper 204. The bulk raw materials fall from the feeding hopper 204 onto the conveyor belt 104. The baffle 103 can prevent the bulk raw materials from moving to other positions on the conveyor belt 104 during the conveying process. Then the conveyor belt 104 rotates and carries the bulk raw materials to the discharge port 106. The bulk raw materials leave the device from the discharge port 106. At the same time, the striking mechanism strikes the conveyor belt 104 above the discharge port 106 to ensure that the bulk materials can completely leave from the discharge port 106.

[0033] The conveyor belt mechanism also includes a conveyor support 101. The length and shape of the conveyor support 101 can be set to various different shapes according to the working scenario, such as a straight line or a Z-shape. Correspondingly, the conveyor belt 104 corresponds to the shape of the conveyor support 101 under the limiting and supporting action of the rotating rollers 105. The enclosed shell 102 corresponds to the shape of the conveyor support 101. Several rotating rollers 105 are rotatably connected to the conveyor support 101. The conveyor belt 104 covers several rotating rollers 105. The outer edge of the baffle 103 contacts the inner wall of the enclosed shell 102. The closed contact between the baffle 103 and the enclosed shell 102 ensures that the bulk raw materials will not be transferred to other positions of the conveyor belt 104. The conveyor belt 104 can be selected in different forms and materials according to the working environment, such as PVC plastic conveyor belts or half-face conveyor belts.

[0034] The power mechanism includes a second gearbox 304 fixedly connected to one side of the front end of the conveying support 101. The output end of the second gearbox 304 is fixedly connected to the front rotating roller 105 via a coupling. The input end of the second gearbox 304 is keyed to a second gear 305. A power motor 301 is bolted to the outside of the second gearbox 304. A half gear 302 is keyed to the output end of the power motor 301, and the half gear 302 can mesh with the second gear 305. A first gearbox 208 is bolted to the bottom of the distribution bin 201. The output end of the first gearbox 208 is fixedly connected to the center of the distribution turntable 202. The input end of the first gearbox 208 is keyed to a first gear 303, and the half gear 302 can mesh with the first gear 303. Machine 301 drives half gear 302. During one revolution, half gear 302 meshes with first gear 303 and second gear 305 respectively. Half gear 302 drives first gear 303 to rotate. First gear 303 drives material distribution turntable 202 to rotate at a certain angle through first gearbox 208, so that the other slot of material distribution turntable 202 corresponds to the position of feeding hopper 204. Second gear 305 drives rotating roller 105 to rotate through second gearbox 304. Rotating roller 105 drives conveyor belt 104 to rotate. Conveyor belt 104 drives baffle 103 to rotate. The position of conveyor belt 104 that does not carry bulk raw materials is exposed below conveyor belt 104. In this way, step-by-step material distribution control can be achieved, improving the durability of the device in harsh working environments.

[0035] The striking mechanism includes a rotating shaft 401 rotatably connected to the conveyor support 101. Several striking plates 402 are fixedly connected to the rotating shaft 401. The other end of each striking plate 402 can contact the conveyor belt 104. A driven actuating block 403 is fixedly connected to the outer end of the rotating shaft 401. A driving actuating wheel 404 is rotatably connected to the outer side of the conveyor support 101. A circumferentially evenly arranged paddles are arranged on the driving actuating wheel 404. A pulley is fixedly connected to one side of the driving actuating wheel 404. Another pulley is fixedly connected to one end of a rotating roller 105 near the discharge port 106. The pulley on the driving actuating wheel 404 and the pulley on the rotating roller 105 are connected by a synchronous belt 405. The striking plates 402 are L-shaped, and their protruding ends can contact the conveyor belt 104. The conveyor belt 104 contacts the impact plate 402, which is made of hollow metal tube. The rotation of the conveyor belt 104 drives the rotating roller 105 on the rear side to rotate. The rotating roller 105 drives the active actuating wheel 404 to rotate through the pulley and the synchronous belt 405. The active actuating wheel 404 actuates the driven actuating block 403 to rotate. The driven actuating block 403 drives the rotating shaft 401 to rotate. The rotating shaft 401 drives the impact plate 402 to rotate. After the active actuating wheel 404 rotates a certain angle, the active actuating wheel 404 and the driven actuating block 403 are no longer engaged. At this time, the impact plate 402 strikes the conveyor belt 104 above the discharge port 106 under the action of gravity, shaking the bulk material remaining on the conveyor belt 104 away from the conveyor belt 104.

[0036] Working principle:

[0037] S1: An external device pours bulk raw materials into the storage hopper 205. The valve motor 207 drives the valve plate 206 to rotate, opening the valve plate 206. The bulk raw materials in the storage hopper 205 fall into the through groove on the distribution turntable 202. The electronic scale assembly 203 can weigh the poured bulk raw materials. After reaching the preset weight, the valve motor 207 drives the valve plate 206 to close. At the same time, the power motor 301 receives the electrical signal from the electronic scale assembly 203 and starts. The power motor 301 drives the half gear 302 to rotate. During one revolution, the half gear 302 meshes with the first gear 303 and the second gear 305 respectively. The half gear 302 drives the first gear 303 to rotate. The first gear 303 drives the material distribution turntable 202 to rotate at a certain angle through the first gearbox 208. The material distribution turntable 202 rotates at a certain angle to rotate the empty channel to the top of the electronic scale assembly 203. The channel on the other side, which is filled with bulk raw materials, rotates to the top of the feeding hopper 204. The bulk raw materials fall from the feeding hopper 204 onto the conveyor belt 104.

[0038] S2: The power motor 301 drives the half gear 302 to rotate. After the half gear 302 drives the material distribution turntable 202 to rotate, the half gear 302 cancels its meshing with the first gear 303 and begins to mesh with the second gear 305. The second gear 305 drives the rotating roller 105 to rotate through the second gearbox 304. The rotating roller 105 drives the conveyor belt 104 to rotate. The conveyor belt 104 drives the baffle 103 to rotate. The position of the conveyor belt 104 that does not carry the bulk raw material is exposed below the conveyor belt 104. The baffle 103 can prevent the bulk raw material from being transferred to other positions of the conveyor belt 104 during the conveying process. Then the conveyor belt 104 rotates and carries the bulk raw material to the discharge port 106. The bulk raw material leaves the device from the discharge port 106.

[0039] S3: While discharging the loose raw materials, the rotation of the conveyor belt 104 drives the rotating roller 105 on the rear side to rotate. The rotating roller 105 drives the active actuating wheel 404 to rotate through the pulley and the synchronous belt 405. The active actuating wheel 404 actuates the driven actuating block 403 to rotate. The driven actuating block 403 drives the rotating shaft 401 to rotate. The rotating shaft 401 drives the striking plate 402 to rotate. After the active actuating wheel 404 rotates a certain angle, the active actuating wheel 404 and the driven actuating block 403 are no longer engaged. At this time, the striking plate 402 strikes the conveyor belt 104 above the discharge port 106 under the action of gravity, shaking the loose raw materials remaining on the conveyor belt 104 away from the conveyor belt 104.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
