[0002] A weighing hopper is an industrial device used for the precise batch weighing of bulk solid materials (such as grains, plastic granules, chemical raw materials, ores, feed, etc.). It is usually used as the core part of a batching system or quantitative packaging system to quickly and automatically weigh, unload, and circulate materials according to preset weight values.

[0003] Existing hopper devices often experience changes in material flow during use, such as clumping, which can lead to hopper blockage. Moreover, material is mostly discharged via a screw feeder, but due to material clumping and blockage, the amount of material falling from the feeding device to the hopper is inconsistent and has poor repeatability. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, materials are mostly fed out by screw feeders, but due to the agglomeration and blockage of materials, the amount of "air-dropped material" from the feeding device to the hopper is inconsistent and the repeatability is poor. Therefore, a precise metering and adjustment structure for weighing hopper is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A precise metering and adjustment structure for a weighing hopper includes a base, a weight sensor fixedly connected to the top of the base, a storage tank disposed inside the base, a placement frame fixedly connected to the outside of the storage tank, and a mounting plate fixedly connected to the inside of the storage tank; and further includes: The agitation assembly includes a dual-head motor fixedly connected inside the mounting plate, a rotating shaft fixedly connected to the output end of the dual-head motor, a first stirring blade and a second stirring blade fixedly connected to the outside of the rotating shaft, and a spiral blade fixedly connected to the lower side of the outside of the rotating shaft. The feeding assembly includes a conveyor belt rotatably connected to a base, a hinge at one end of the conveyor belt, a slider fixedly connected to the end of the hinge away from the conveyor belt, and a locking block slidably connected inside the slider.

[0006] As a preferred technical solution of this application, a controller is fixedly connected to the outside of the base, and the controller is electrically connected to the weight sensor.

[0007] As a preferred technical solution of this application, the base is provided with a plurality of support legs, one of which has a sliding groove, the inside of which has a slot, and the outside of the base is provided with a moving component.

[0008] As a preferred technical solution of this application, the bottom of the placement frame is attached to the upper part of the weight sensor, the bottom end of the storage tank is fixedly connected to a discharge pipe, the inside of the discharge pipe is rotatably connected to a material distribution partition, the end of the material distribution partition is fixedly connected to a drive motor, and the drive motor is located outside the discharge pipe.

[0009] As a preferred technical solution of this application, the outer surface of the slider is slidably connected to the inside of the groove, a motor is fixedly connected inside the slider, a threaded rod is fixedly connected to the output end of the motor, and the locking block is threadedly connected to the outside of the threaded rod.

[0010] As a preferred technical solution of this application, the first stirring blade is disposed on the upper part of the mounting plate, the spiral blade is disposed between the mounting plate and the discharge pipe, and the second stirring blade is disposed outside the spiral blade.

[0013] Compared with the prior art, this utility model provides a precise metering and adjustment structure for a weighing hopper, which has the following beneficial effects: 1. The set stirring component drives the rotating shaft to rotate through the dual-head motor, which in turn drives the first stirring blade and the second stirring blade to rotate, stirring the material to maintain its fluidity and reduce the occurrence of lumps. At the same time as the rotating shaft rotates, it drives the spiral blade to rotate, pushing the material into the inside of the material distribution plate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0018] Reference Figure 1-4A precise metering and adjustment structure for a weighing hopper includes a base 1, a weight sensor 101 fixedly connected to the top of the base 1, a storage tank 2 disposed inside the base 1, a placement frame 201 fixedly connected to the outside of the storage tank 2, and a mounting plate 205 fixedly connected to the inside of the storage tank 2. It also includes a stirring assembly and a feeding assembly. The stirring assembly includes a dual-head motor 3 fixedly connected inside the mounting plate 205, a rotating shaft 301 fixedly connected to the output end of the dual-head motor 3, a first stirring blade 302 and a second stirring blade 303 fixedly connected to the outside of the rotating shaft 301, and a spiral blade fixedly connected to the lower side of the outside of the rotating shaft 301. 304; The feeding assembly includes a conveyor belt 4 rotatably connected to the base 1, a hinge 401 disposed at one end of the conveyor belt 4, a slider 402 fixedly connected to the end of the hinge 401 away from the conveyor belt 4, and a locking block 405 slidably connected inside the slider 402; a controller 102 is fixedly connected to the outside of the base 1, and the controller 102 is electrically connected to the weight sensor 101; a precise metering and adjustment structure for a weighing hopper, further wherein the base 1 is provided with several support legs, and one of the support legs is provided with a sliding groove 103, and a locking slot 104 is provided inside the sliding groove 103; a moving component is provided on the outside of the base 1.

[0019] The weight sensor 101 monitors the weight of the material in the storage tank 2 in real time and transmits the data to the controller 102. The controller 102 can observe the current weight of the tank and the weight at discharge. After the corresponding weight is discharged, the internal components can be controlled to stop working. Before discharge, one end of the conveyor belt 4 is pulled to make it rotate and adjust one end to a certain height. Thus, the conveyor belt 4 can be adjusted according to the different heights of the containers containing the materials, which can be conveniently adapted to different usage environments and expand the applicability of the device. The conveyor belt 4 slides by pulling the slider 402 through the hinge 401, and the locking block 405 extends into the locking groove 104 to limit and fix the slider 402, keeping the conveyor belt 4 stable. The angle of the conveyor belt 4 is adjusted to facilitate the adjustment of the angle. Then, the dual-head motor 3 drives the rotating shaft 301 to rotate. The first stirring blade 302 and the second stirring blade 303 stir the material, effectively breaking the bridging and adhesion of the material. The spiral blade 304 rotates synchronously to achieve forced feeding, ensuring that the material falls evenly and stably. This solves the metering error problem caused by material clumping in traditional hoppers. It should be noted that the connection between the hinge 401 and the conveyor belt 4 is telescopic. The end of the conveyor belt 4 is fixedly connected to a connecting block. One end of the hinge 401 is inserted into the inside of the connecting block. When the slider 402 moves, the extension length of the end of the hinge 401 is different depending on the distance, so as to ensure the stable sliding of the slider 402.

[0020] Reference Figure 3 and Figure 5A precise metering and adjustment structure for a weighing hopper is further provided, wherein the bottom of the placement frame 201 is attached to the upper part of the weight sensor 101, the bottom end of the storage tank 2 is fixedly connected to the discharge pipe 202, the inside of the discharge pipe 202 is rotatably connected to the material distribution baffle 203, the end of the material distribution baffle 203 is fixedly connected to the drive motor 204, and the drive motor 204 is located outside the discharge pipe 202; the first stirring blade 302 is located on the upper part of the mounting plate 205, the spiral blade 304 is located between the mounting plate 205 and the discharge pipe 202, and the second stirring blade 303 is located outside the spiral blade 304.

[0021] The weight sensor 101 senses the total weight of the storage tank 2 in real time through the support frame 201. The drive motor 204 receives the command from the controller 102 to precisely rotate the material distribution baffle 203. The material distribution baffle 203 adjusts the effective flow area of ​​the discharge pipe 202 by rotating the angle, so as to achieve precise stepless control of the discharge flow rate. The first stirring blade 302 rotates at the top to break up any material arches that may be formed. The second stirring blade 303 rotates at the bottom to further loosen the material and assist in feeding it to the spiral blade 304. The spiral blade 304 provides forced downward conveying power to overcome material adhesion. The multi-stage stirring and conveying combination ensures the uniform flowability and continuous feeding of different materials, and solves the problems of material jamming and metering pulse that are easy to occur in traditional gate control.

[0022] The outer surface of the slider 402 is slidably connected to the inside of the slide groove 103. The inside of the slider 402 is fixedly connected to the motor 403. The output end of the motor 403 is fixedly connected to the threaded rod 404. The locking block 405 is threadedly connected to the outside of the threaded rod 404. The surface of the conveyor belt 4 is fixedly connected to the partition plate. One end of the conveyor belt 4 is set at the lower end of the discharge pipe 202. The conveyor belt 4 is rotatably connected to the outside of the support leg of the base 1 through the bearing.

[0023] Motor 403 drives threaded rod 404 to rotate forward or reverse. The rotation of threaded rod 404 drives locking block 405 to move precisely along its axis. Locking block 405 extends to engage with locking groove 104 or retracts to disengage to lock or release slider 402. The partition on the surface of conveyor belt 4 effectively controls the material to prevent it from slipping down to the downward-sloping end of conveyor belt 4. The bearing configuration allows for convenient height adjustment of conveyor belt 4 to adapt to different working environments.

[0024] Reference Figure 2 and Figure 4 A precise metering and adjustment structure for a weighing hopper is further provided, wherein the moving component includes a fixed frame 5 fixedly connected to the outside of the support legs of the base 1, an mounting frame 501 fixedly connected inside the fixed frame 5, an electric push rod 502 fixedly connected inside the mounting frame 501, and a caster wheel 503 fixedly connected to the output end of the electric push rod 502.

[0025] When the equipment needs to be moved, the electric push rod 502 is activated. The output end of the electric push rod 502 extends and pushes the caster wheel 503 downward. The caster wheel 503 contacts the ground and lifts the support leg of the base 1 off the ground. At this time, the equipment can be moved flexibly by pushing it and using the caster wheel 503. After the equipment is in place, the electric push rod 502 retracts and drives the caster wheel 503 to rise. The support leg of the base 1 contacts the ground again to provide stable support. This realizes the rapid switching between mobility and stability of the equipment and effectively avoids the impact of vibration caused by traditional handling methods on measurement accuracy.

[0026] Specifically, in use, the present invention works as follows: Material is placed inside the storage tank 2. The weight sensor 101 monitors the weight of the material inside the storage tank 2 in real time and transmits the data to the controller 102. The controller 102 can observe the current weight of the tank and the weight at discharge. By setting the required material weight, the system can be shut off promptly when the specified weight is discharged. Before discharge, one end of the conveyor belt 4 is pulled to rotate it, and the other end is adjusted to a certain height. The conveyor belt 4 slides through the hinge 401, pulling the slider 402. After the conveyor belt 4 is adjusted, the motor 403 is turned on, driving the threaded rod 404 to rotate, pushing the locking block 405 into the slot 104 to fix the conveyor belt 4. Simultaneously, the dual-head motor 3 is turned on. The rotating shaft 301 is driven to rotate, which in turn drives the first stirring blade 302, the second stirring blade 303, and the spiral blade 304 to rotate simultaneously. The rotation of the first stirring blade 302 and the second stirring blade 303 can break up material agglomerates or blockages, while the spiral blade 304 can push the material downwards. The material is eventually pushed into the interior of the distribution partition 203. Then, the drive motor 204 is started to rotate the distribution partition 203, and the material is placed into the conveyor belt 4 in batches. The conveyor belt 4 can then deliver the material to the designated position. At the same time, the weight sensor 101 can detect the weight fluctuation after the material falls, thereby determining how much material has been discharged, which facilitates accurate measurement and improves the efficiency of use.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
