Abstract
Description
Technical Field
[0001] This utility model belongs to the field of controlled-release fertilizer production technology, specifically a raw material supply system for a controlled-release fertilizer production line. Background Technology
[0002] Controlled-release fertilizers are an advanced form of slow-release fertilizers. They mainly use coating technology to control the release of nutrients, achieving safety, long-lasting effects, and high efficiency. They represent a major direction in modern fertilizer development and are suitable for mechanized production, especially for meeting the needs of simultaneous sowing and fertilization.
[0003] In the production of controlled-release fertilizers, raw materials need to be transported to the preparation equipment for processing. Currently, the raw materials are weighed by workers in buckets and then poured into the conveying auger through a hopper as needed. However, this method is not only wasteful of workers' time and energy due to manual pouring, but also results in over- or under-pouring, requiring multiple adjustments and leading to low production efficiency. Utility Model Content
[0004] This invention provides a raw material supply system for a controlled-release fertilizer production line to address the deficiencies in the prior art.
[0005] This utility model is achieved through the following technical solution:
[0006] A raw material supply system for a controlled-release fertilizer production line includes a support frame with a support plate mounted on it. The right bottom surface of the support plate is hinged to the support frame, and one end of a support electric telescopic rod is hinged downwards to the left side of the bottom surface of the support plate. The other end of the support electric telescopic rod is hinged to the support frame. A hopper with a through-hole on the right side is provided on the top surface of the support plate. A baffle gate is hinged to the right side of the hopper to block the hopper. One end of an opening electric telescopic rod is hinged to both the front and rear sides of the baffle gate. The other end of the opening electric telescopic rod is hinged to the corresponding side of the hopper. A base plate is also fixedly mounted on the support frame. A weighing pan is provided on the top surface of the base plate. The weighing pan is opposite to the feed port of the support plate and is located above the feed hopper. Limit rods are fixedly provided at the four corners of the bottom surface of the weighing pan. Limiting grooves for the insertion of the limit rods are provided on the top surface of the base plate. A pressure sensor is provided on the base plate in contact with the bottom surface of the weighing pan. The pressure sensor is connected to a display screen mounted on the support frame.
[0007] First, workers load raw materials into the hopper. The gate, under gravity, prevents the materials from sliding down. When a specific amount of material needs to be loaded into the hopper, the electric support rod is activated. The extended rod rotates the base plate along its hinge point, causing the hopper to tip over. Simultaneously, the opening rod extends, opening the gate. Because the hopper tipps from left to right, the material falls onto the weighing pan. The weighing pan presses against a pressure sensor, which weighs the material and displays the result on the screen. When the material is close to the desired amount, the worker controls the opening rod to retract, and the support rod retracts as well. This closes the gate and levels the hopper. The material is then pushed from the weighing pan into the hopper. This process not only saves workers time and effort compared to manual weighing but also reduces errors and improves efficiency.
[0008] Preferably, the base plate has upwardly extending side plates fixedly connected to both its front and rear sides. These side plates effectively prevent raw materials from falling off the weighing pan.
[0009] Preferably, the side plate is longer than the bottom plate, and the opposite surfaces of the side plates have grooves along their length. Scrapers are fitted between the side plates, and the scrapers are fixedly connected to the corresponding side sliders. The bottom surface of the scraper and the top surface of the weighing pan are on the same transverse plane. The scraper has threaded holes in the transverse direction, and a lead screw is threaded into the holes. The lead screw is coaxially and fixedly connected to the motor shaft, and the motor is fixedly mounted on the frame. After weighing, the motor is started. The rotation of the motor shaft drives the lead screw to rotate, which in turn causes the scraper to rotate. Under the constraint of the slider and the grooves, the scraper moves from right to left, thus pushing the raw material from the weighing pan into the feed hopper. This not only saves time spent manually pushing the material, but also, because of the slow pushing, even if the amount of material on the weighing pan exceeds the required amount, the display screen shows that the pushing stops when the required amount of material falls, further ensuring the accuracy of the material falling into the feed hopper.
[0010] Preferably, a brush is fixedly connected to the right side of the scraper, with the bottom surface of the brush located below the bottom surface of the scraper. The brush can then clean the weighing pan.
[0011] Preferably, the baffle is fixedly connected to one end of a horizontal rod, and a push plate is fixedly installed at the other end of the horizontal rod. The push plate is located on the left side of the weighing pan, and the baffle is located on the right side of the weighing pan. The push plate can act as a blockage, preventing raw materials from falling off the weighing pan when the hopper is discharging material, and when the scraper moves away from the weighing pan, it will not affect the falling of raw materials from the weighing pan.
[0012] Preferably, the device further includes a conveying device comprising a conveyor belt, the unloading end of which is opposite to the support plate and located outside the rotation trajectory of the hopper. The conveyor belt makes conveying raw materials onto the hopper more labor-saving.
[0013] The beneficial effects of this utility model are as follows: the use of this application can achieve accurate weighing of materials through weighing pan and hopper, saving the time and physical effort consumed by manual weighing, while the error is low and efficiency can be improved.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] A raw material supply system for a controlled-release fertilizer production line, such as Figure 1 and Figure 2As shown. It includes a bracket 1, on which a support plate 2 is mounted. The right bottom surface of the support plate 2 is hinged to the bracket 1. One end of a supporting electric telescopic rod 4 is hinged downwards to the left side of the bottom surface of the support plate 2. The other end of the supporting electric telescopic rod 4 is hinged to the bracket 1. A cargo hopper 3 with a through-hole on the right side is mounted on the top surface of the support plate 2. A baffle 6 for sealing the cargo hopper 3 is hinged to the right side of the baffle. One end of an opening electric telescopic rod 5 is hinged to both the front and rear sides of the baffle. The other end of the opening electric telescopic rod 5 is hinged to the corresponding side of the cargo hopper 3. A base plate 7 is also fixedly mounted on the bracket 1. A weighing pan 8 is mounted on the top surface of the base plate 7. The weighing pan 8 is opposite to the discharge port of the support plate 2 and is located above the feed hopper 17. Limiting rods are fixedly mounted at the four corners of the bottom surface of the weighing pan 8. Limiting grooves for inserting the limiting rods are formed on the top surface of the base plate 7. A pressure sensor is mounted on the base plate 7, contacting the bottom surface of the weighing pan 8. The pressure sensor is connected to a display screen mounted on the bracket 1.
[0021] The base plate 7 has upwardly extending side plates 9 fixedly connected to both its front and rear sides. The length of the side plates 9 is greater than that of the base plate 7. The opposite surfaces of the side plates 9 are provided with sliding grooves 10 along their length. Scrapers 11 are adapted between the side plates 9. The scrapers 11 are fixedly connected to the corresponding side sliders. The bottom surface of the scraper 11 and the top surface of the weighing pan 8 are located on the same horizontal plane. The scraper 11 has a threaded hole in the horizontal direction. A lead screw 12 is threaded in the threaded hole. The lead screw 12 is coaxially fixedly connected to the rotating shaft of the motor 13. The motor 13 is fixedly mounted on the frame.
[0022] In use, the worker first loads the raw materials into the hopper 3. The baffle 6, under the action of gravity, prevents the raw materials from sliding down naturally. When a certain amount of raw materials needs to be loaded into the feed hopper 17, the electric telescopic support rod 4 is activated. The electric telescopic support rod 4 extends, causing the base plate 7 to rotate along its hinge point, which in turn causes the hopper 3 to tip over along its hinge point. At the same time, the electric telescopic opening rod 5 extends, and the baffle 6 opens. Since the hopper 3 is tilted from left to right, the raw materials fall onto the weighing pan 8. The weighing pan 8 presses the pressure sensor, which weighs the materials and displays the results on the display screen. When the required raw materials are close, the worker controls the electric telescopic opening rod 5 to retract while the electric telescopic support rod 4 retracts, thus closing the hopper 3 with the baffle 6 and making the hopper 3 horizontal. After weighing is completed, motor 13 is started. The rotation of the motor 13 shaft drives the lead screw 12 to rotate, which in turn causes the scraper 11 to rotate. Under the constraint of the slider and the slide groove 10, the scraper 11 moves from right to left, thus pushing the raw material from the weighing pan 8 into the feed hopper 17. This not only saves the time spent by workers manually pushing the material, but also, because of the slow pushing, even if the amount of raw material on the weighing pan 8 exceeds the required amount, the push can be stopped when the amount of raw material falls to the quantitative amount by observing the display screen, thereby further ensuring the accuracy of the raw material falling into the feed hopper 17. Therefore, this application not only saves the time and physical strength of workers spent on manual weighing, but also has low error and improves efficiency. The side plate 9 can effectively prevent the raw material from falling from the weighing pan 8.
[0023] A brush 14 is fixedly connected to the right side of the scraper 11, with the bottom surface of the brush 14 located below the bottom surface of the scraper 11. The brush 14 can clean the weighing pan 8.
[0024] The baffle is fixedly connected to one end of a horizontal rod, and a push plate 15 is fixedly installed at the other end of the horizontal rod. The push plate 15 is located on the left side of the weighing pan 8, and the baffle is located on the right side of the weighing pan 8. The push plate 15 can act as a blockage, preventing the raw materials from falling off the weighing pan 8 when the hopper 3 is discharging material, and when the scraper 11 moves away from the weighing pan 8, it will not affect the falling of raw materials from the weighing pan 8.
[0025] The device also includes a conveying device, which comprises a conveyor belt 16. The discharge end of the conveyor belt 16 is opposite to the support plate 2 and is located outside the rotation trajectory line of the hopper 3. The conveyor belt 16 makes it easier to transport raw materials onto the hopper 3.
[0026] The use of this application enables accurate weighing of materials through the weighing pan 8 and the hopper 3, saving the time and effort consumed by manual weighing, while also having low error and improving efficiency.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
