Abstract
Description
Technical Field
[0001] This utility model relates to the field of seed packaging technology, specifically to a multi-station unloading scale. Background Technology
[0002] Seed packaging typically refers to the process of packaging and sorting seeds to ensure that they maintain their quality and are easy to manage during storage, transportation, and use.
[0003] During the seed packaging process, workers often need to feed seeds into packaging bags in a quantitative manner. That is, workers need to weigh a certain amount of seeds and then feed them into packaging bags. Currently, the commonly used weighing equipment mostly uses a dual vibrating plate feeding method. The equipment first feeds a large amount of seeds into the weighing hopper through a large vibrating plate. When the amount of seeds is about to reach the weighing requirement, it can switch to a small vibrating plate to feed a small batch of seeds until the required weight is reached. Although this method can achieve accurate weighing of seeds, the weighing efficiency is low, which is not conducive to the efficient packaging of seeds in factories. Therefore, it still has certain shortcomings in its use.
[0004] In conclusion, it is necessary to invent a multi-station unloading scale. Utility Model Content
[0005] Therefore, this utility model provides a multi-station unloading scale to solve the problem that although this method can also accurately weigh seeds, its weighing efficiency is low, which is not conducive to the efficient packaging of seeds in factories.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-station unloading scale, including a frame, a storage hopper for storing materials fixed at the top of the outer wall of the frame, a discharge hopper provided on the inner wall of the frame below the storage hopper, and a weighing component for unloading and weighing provided between the top of the outer wall of the storage hopper and the bottom of the outer wall of the storage hopper.
[0007] The weighing component includes a conveying mechanism and a weighing hopper. The conveying mechanism is installed on the inner wall of the frame and located below the discharge port of the storage hopper. The weighing hopper is fixed on the inner side of the frame and located between the conveying mechanism and the discharge hopper.
[0008] Preferably, the material conveying mechanism includes a material conveying hopper, and a plurality of the material conveying hoppers are disposed inside the frame and below the discharge port of the storage hopper. The material conveying hoppers are all fixedly connected to the inner wall of the frame by a bracket.
[0009] Preferably, a baffle plate frame is provided at the bottom of the outer wall of the conveying hopper and below the discharge port. The upper end of the baffle plate frame is rotatably connected to the bottom of the front and rear ends of the outer wall of the conveying hopper via a rotating shaft.
[0010] Preferably, a second servo motor is provided on one side of the outer wall of the conveying hopper. One end of the second servo motor is fixedly connected to the front end of the outer wall of the conveying hopper through a fixing plate. A swing arm is fixed to the output end of the second servo motor. The end of the swing arm away from the second servo motor is connected to the outer wall of the baffle frame through a connecting rod.
[0011] Preferably, the weighing hopper includes a hopper body, and a plurality of hopper bodies are disposed below the conveying hopper, the number of hopper bodies being the same as the number of conveying hoppers, and the hopper bodies being disposed above the discharge hopper.
[0012] Preferably, both sides of the bottom of the outer wall of the bucket are rotatably connected to a sealing plate for controlling the discharge of material from the bottom outlet of the bucket, and the two sealing plates are connected by a hinge arm.
[0013] Preferably, a mounting frame is fixed to one side of the outer wall of the bucket, and the bucket is fixed to the inner wall side of the frame through the mounting frame. A first servo motor for controlling the opening and closing of the sealing plate is installed on the mounting frame. A weighing sensor for weighing the bucket is provided on the outer wall side of the bucket and at the bottom of the first servo motor.
[0014] The beneficial effects of this utility model are:
[0015] In this invention, the operator can control the baffle frame to rotate via the second servo motor, so that the baffle frame can block the bottom opening of the feeding hopper. This allows the bottom opening of the feeding hopper to be fully opened when a large amount of seeds need to be transported, and to be blocked when seed transport needs to be restricted, thereby improving the seed weighing accuracy of the hopper and making it more convenient for operators to use.

Detailed Implementation
[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0024] See attached document Figures 1-6 This utility model provides a multi-station unloading scale, including a frame 100. A storage hopper 110 for storing materials is fixed to the top of the outer wall of the frame 100. The storage hopper 110 is for storing seeds to be packaged. A discharge hopper 120 is provided on the inner wall of the frame 100 below the storage hopper 110. The discharge hopper 120 is mainly for conveying the weighed seeds to packaging bags or boxes for storage. The top and bottom of the outer wall of the storage hopper 110 are connected... A weighing component for feeding and weighing is provided between the ends. The weighing component includes a conveying mechanism 200 and a weighing hopper 130. The conveying mechanism 200 is installed on the inner wall of the frame 100 and located below the discharge port of the storage hopper 110. The weighing hopper 130 is fixed on the inner side of the frame 100 and located between the conveying mechanism 200 and the discharge hopper 120. The conveying mechanism 200 is provided to control the amount of seeds entering the weighing hopper 130, and the weighing hopper 130 is mainly used to weigh the seeds conveyed by the conveying mechanism 200.
[0025] The feeding mechanism 200 includes multiple feeding hoppers 210, all of which are located inside the frame 100 and below the discharge port of the storage hopper 110. Seeds in the storage hopper 110 can enter the feeding hoppers 210. Each feeding hopper 210 is fixedly connected to the inner wall of the frame 100 via a bracket. A baffle plate 230 is installed at the bottom of the outer wall of each feeding hopper 210, below the discharge port. The upper end of each baffle plate 230 is rotatably connected to the bottom of the front and rear ends of the outer wall of the feeding hopper 210 via a rotating shaft. The baffle plate 230 can control the size of the bottom opening of the feeding hopper 210 based on the weighing data. Specifically, when initially feeding material into the weighing hopper 130, the operator can open the bottom outlet of the feeding hopper 210 to its maximum, and when the required weighing weight is almost reached... When the material baffle 230 closes the bottom outlet of the feeding hopper 210, the seed discharge amount is reduced or the seed conveying is stopped. A second servo motor 220 is provided on one side of the outer wall of the feeding hopper 210. One end of the second servo motor 220 is fixedly connected to the front end of the outer wall of the feeding hopper 210 through a fixing plate. A swing arm 240 is fixed to the output end of the second servo motor 220. The end of the swing arm 240 away from the second servo motor 220 is connected to the outer wall of the baffle 230 through a connecting rod 241. The second servo motor 220 can control the swing arm 240 and the connecting rod 241 to rotate, thereby controlling the baffle 230 to swing at the bottom of the feeding mechanism 200, so as to adjust the bottom opening angle of the feeding hopper 210.
[0026] The weighing hopper 130 includes a hopper body 131. Multiple hopper bodies 131 are arranged below the conveying hopper 210, with the number of hopper bodies 131 matching the number of conveying hoppers 210. Each hopper body 131 is positioned above the discharge hopper 120. Sealing plates 134 are rotatably connected to both sides of the bottom of the outer wall of each hopper body 131 to control the discharge from the bottom outlet. Two sealing plates 134 are connected by a hinge arm. The sealing plates 134 can control the discharge from the hopper body 131 by opening and closing. During weighing, the sealing plates 134 close the bottom opening of the hopper body 131 to prevent seed leakage. A mounting bracket 132 is fixed to one side of the outer wall of the bucket body 131. The bucket body 131 is fixed to the inner wall side of the frame 100 through the mounting bracket 132. A first servo motor 133 is installed on the mounting bracket 132 to control the opening and closing of the sealing plate 134. A weighing sensor 135 for weighing the bucket body 131 is set at the outer wall side of the bucket body 131 and at the bottom of the first servo motor 133. The first servo motor 133 can be a telescopic motor, which can pull the sealing plate 134 connected to it to rotate. The sealing plates 134 can be linked by a hinge arm so that they can be opened and closed at the same time.
[0027] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above description, then connect all electrical equipment to an external power supply, and control the operation of the device through an external controller. The control programs of all electrical equipment are edited by the production personnel in advance before production. This utility model does not make any technical improvements, but assumes that it can normally meet the needs of personnel.
[0028] First, personnel can pre-set the seed weighing data using a PLC device, and then input the seeds to be packaged into the storage hopper 110. The storage hopper 110 will then convey the seeds to the conveying hopper 210. When weighing is required, the second servo motor 220, after being powered on, will control the baffle plate 230 to rotate outward, allowing the seeds to fall through the conveying hopper 210 into the hopper body 131. The seeds falling into the hopper body 131 will increase its weight. The weighing sensor 135 can detect the weight of the hopper body 131 in real time, and the weight of the seeds can be obtained by subtracting the weight of the hopper body 131 from the weight of the seeds. When the seeds are close to reaching the required weighing weight, the second servo motor 220 will control the baffle plate 230 to rotate outward. The material plate frame 230 rotates in the opposite direction, causing the baffle plate frame 230 to partially block the outlet of the conveying hopper 210. This reduces the number of seeds falling into the hopper 131, allowing the hopper 131 to weigh the seeds more accurately until the required size is reached. Once the size is reached, the baffle plate frame 230 closes the outlet of the conveying hopper 210, and the first servo motor 133 is energized to control the opening of the sealing plate 134, allowing the seeds in the hopper 131 to fall into the discharge hopper 120. The discharge hopper 120 then transports the seeds to the packaging bag for subsequent packaging. By alternately controlling the opening and closing of the sealing plate 134, multiple hoppers 131 can be controlled to sequentially transport seeds through the discharge hopper 120 to the packaging bag.
[0029] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
