Description

Technical Field

[0001] This utility model relates to the technical field of solid fertilizer conveying devices, specifically a solid fertilizer mixing and feeding device. Background Technology

[0002] Solid fertilizer, as an important type of fertilizer, occupies an indispensable position in agricultural planting. It contains abundant macroelements such as nitrogen, phosphorus, and potassium, as well as microelements such as calcium, magnesium, sulfur, iron, and zinc, providing comprehensive nutrient support for crop growth. The rational application of solid fertilizer can not only significantly increase crop yield but also effectively improve crop quality, enhance soil fertility, and thus improve agricultural economic benefits. This is of crucial significance for ensuring food security and maintaining sustainable agricultural development.

[0003] In current agricultural practices, solid fertilizers are typically in granular form. However, when air humidity is high, solid fertilizers are prone to clumping. This clumping not only affects the normal flow of fertilizer but also blocks the outlet of the fertilizer applicator, preventing proper application. Once the applicator is clogged, the correct amount of fertilizer cannot be guaranteed, making it difficult for farmers to provide sufficient nutrients to crops according to the planned fertilization schedule, thus impacting crop growth and yield. Furthermore, clogging affects the precision of fertilizer dispensing, resulting in incorrect fertilizer solution concentrations, severely affecting fertilization effectiveness and crop growth, and increasing farmers' labor intensity and time costs. To solve the clogging problem, farmers may need to frequently clean the fertilizer applicator, which not only delays fertilization but may also damage the applicator, affecting its lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide a solid fertilizer mixing and feeding device. The rotating stirring fins inside the cylinder can break up the clumped solid fertilizer, and the rotation of the feeding impeller can ensure feeding accuracy, thus solving the problems in the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a solid fertilizer mixing and feeding device, including a support base, a feeding box installed on the support base, a connected material cylinder installed on the feeding box, a detachable cover installed at the end of the material cylinder away from the feeding box, a vertically arranged rotating rod installed inside the material cylinder, stirring blades installed on the outer periphery of the rotating rod, a first motor installed inside the support base, the output shaft of the first motor connected to the rotating rod, a feeding port that can be opened and closed is opened between the material cylinder and the feeding box, a feeding trough connected to the feeding port is opened inside the feeding box, a feeding impeller is installed in the feeding trough, a second motor is installed inside the feeding box, the output shaft of the second motor is connected to the rotating shaft of the feeding impeller, and a connected guide pipe is installed on the feeding box corresponding to the position of the feeding trough. When the feeding port is opened, the first motor starts to drive the stirring blades to rotate, and the second motor starts to drive the feeding impeller to rotate, which allows the solid fertilizer in the material cylinder to fall into the guide pipe. A metering module is installed at the bottom of the support base. The metering module includes a load-bearing plate at the bottom of the support base, a mounting base under the load-bearing plate, and an electronic scale between the mounting base and the load-bearing plate. Gaskets are provided between the electronic scale and the mounting base, and between the electronic scale and the load-bearing plate. A baffle plate is installed at the end of the rotating rod near the discharge port. When the rotating rod drives the baffle plate to rotate, it can completely block the discharge port. When the baffle plate rotates to separate from the discharge port, the discharge port is in the open state. The rotating rod is divided into two detachable parts. The lower part of the rotating rod is connected to the output shaft of the first motor. A bearing that mates with the upper part of the rotating rod is installed inside the cover. The upper and lower parts of the rotating rod are connected as one unit by threaded fasteners. The feeding box is equipped with a gate plate that can block the feeding trough. The gate plate has a slot that matches the feeding trough. The feeding box has a slide that matches the gate plate. A rack is installed on one side of the gate plate. A third motor is installed in the feeding box. A gear that meshes with the rack is installed on the output shaft of the third motor. When the third motor is started, it can drive the gate plate to move to open and close the feeding trough.

[0006] The positive effects of this utility model are as follows: The solid fertilizer mixing and dispensing device described herein features a vertical rotating rod and stirring blades inside the material cylinder. When the first motor starts and drives the rotating rod to rotate, the stirring blades can fully stir the solid fertilizer inside the material cylinder. In environments with high humidity, solid fertilizer is prone to clumping; the rotation of the stirring blades can break up the clumped fertilizer, restoring it to granular form, effectively avoiding the problem of clogging the dispensing port due to clumping. This design ensures that the fertilizer can smoothly fall from the material cylinder into the dispensing box and then be dispensed through the guide pipe, guaranteeing the continuity and smoothness of the fertilization process, reducing fertilization interruptions and equipment cleaning time caused by blockages, and greatly improving fertilization efficiency. The feeding impeller installed inside the dispensing box is a key component for achieving uniform dispensing. The second motor starts and drives the feeding impeller to rotate; the blades of the feeding impeller can precisely control the amount of fertilizer falling, allowing the fertilizer to enter the guide pipe through the dispensing trough at a uniform speed and flow rate. Compared with traditional fertilization devices, this device controls the amount of fertilizer discharged through an impeller, which can reduce the error between the actual amount discharged and the set amount, ensuring accurate discharge. It can prepare different concentrations of water and fertilizer solution according to different crops, providing a stable supply of nutrients to the crops and avoiding adverse effects on crop growth due to mismatched water and fertilizer solution concentrations. This helps to improve crop yield and quality, promote the sustainable development of agricultural production, and bring more convenience and benefits to agricultural production.

Detailed Implementation

[0008] The solid fertilizer mixing and feeding device described in this utility model, such as Figure 1-5 As shown, it includes a support base 1, a feeding box 2 installed on the support base 1, and a connected material cylinder 3 installed on the feeding box 2. The material cylinder 3 is used to store solid fertilizer.

[0009] The end of the material cylinder 3 away from the feeding box 2 is equipped with a detachable cover 4. After opening the cover 4, solid fertilizer can be filled into the feeding box 2. A vertically arranged rotating rod 5 is installed inside the material cylinder 3, and stirring wings 6 are installed on the outer periphery of the rotating rod 5. A first motor 7 is installed in the support base 1. The output shaft of the first motor 7 is connected to the rotating rod 5. The first motor 7 drives the stirring wings 6 to rotate inside the material cylinder 3, which can break up the caking solid fertilizer, so as to solve the problem of caking and blockage and realize the subsequent normal feeding.

[0010] A discharge port 8 that can be opened and closed is provided between the material cylinder 3 and the discharge box 2. A discharge trough 9 connected to the discharge port 8 is provided in the discharge box 2. The solid fertilizer in the material cylinder 3 can enter the discharge trough 9 in the discharge box 2 through the discharge port 8.

[0011] To ensure feeding accuracy, a feeding impeller 10 is installed in the feeding trough 9, and a second motor 11 is installed in the feeding box 2. The output shaft of the second motor 11 is connected to the rotating shaft of the feeding impeller 10. Corresponding to the position of the feeding trough 9, a connecting guide pipe 12 is installed on the feeding box 2. When the feeding port 8 is opened, the first motor 7 starts to drive the stirring blades 6 to rotate, and the second motor 11 starts to drive the feeding impeller 10 to rotate, which allows the solid fertilizer in the material cylinder 3 to fall into the guide pipe 12.

[0012] The main function of the feeding impeller 10 is to precisely control the feeding accuracy. The rotation of the feeding impeller 10 transports the falling fertilizer into the guide pipe 12. By adjusting the rotation speed of the feeding impeller 10, the control accuracy of the feeding weight can be improved more effectively.

[0013] The synergistic action of the stirring fins 6 and the feeding impeller 10 effectively prevents fertilizer clumping and achieves precise feeding. The feeding impeller 10 operates by alternating between forward and reverse rotation to prevent the impeller from getting stuck during the feeding process.

[0014] When using the solid fertilizer mixing and feeding device described in this utility model, the material cylinder 3 contains the required solid fertilizer. The first motor 7 starts and drives the stirring blades 6 to rotate, breaking up the solid fertilizer for easy falling. The feeding port 8 opens, and the second motor 11 starts and drives the feeding impeller 10 to rotate. The solid fertilizer can then enter the guide pipe 12 through the feeding port 8 and the feeding trough 9 to complete the feeding. The feeding speed and amount of solid fertilizer can be adjusted by controlling the rotation speed and start / stop of the feeding impeller 10.

[0015] Furthermore, in order to ensure the accurate dispensing of solid fertilizer, a metering module is installed at the bottom of the support base 1. The metering module includes a load-bearing plate 13 located at the bottom of the support base 1, an installation base 14 located on the underside of the load-bearing plate 13, an electronic scale 15 located between the installation base 14 and the load-bearing plate 13, and gaskets 16 located between the electronic scale 15 and the installation base 14, and between the electronic scale 15 and the load-bearing plate 13.

[0016] The metering module installed at the bottom of the support base 1 provides strong support for the precise control of fertilizer application. The electronic scale 15 can measure the weight of fertilizer on the load-bearing plate in real time and feed the data back to the operator or control system. By setting the fertilizer application rate, the operator can accurately control the amount of fertilizer used each time, avoiding fertilizer waste. At the same time, precise metering of fertilizer application can also reasonably adjust the fertilizer application rate according to the growth needs of different crops and soil fertility conditions, improving fertilizer utilization and reducing agricultural production costs. The setting of the shim 16 can reduce friction and vibration between the electronic scale and the load-bearing plate 13 and the mounting base 14, improving the accuracy and stability of metering. The metering module can accurately weigh according to the fertilization strategy, effectively improving the yield and quality of crops, significantly reducing fertilizer waste, and realizing a green and environmentally friendly agricultural production model.

[0017] Furthermore, in order to control the opening and closing of the discharge port 8, a baffle plate 17 can be installed at one end of the rotating rod 5 near the discharge port 8. When the rotating rod 5 drives the baffle plate 17 to rotate, it can completely block the discharge port 8. When the baffle plate 17 rotates to separate from the discharge port 8, the discharge port 8 is in the open state.

[0018] The baffle plate 17 can completely block or open the discharge port 8 as the rotating rod 5 rotates. The operator can control the start and stop of the discharge at any time according to the actual fertilization needs. When the stirring blade 6 rotates, the baffle plate 17 rotates and separates from the discharge port 8, and the discharge port 8 discharges the fertilizer. When it needs to be closed, the sensor detects that the baffle plate 17 is stopped in the closed position, and then stops the motor rotation. This design has both a stirring function to prevent fertilizer from clumping and effective control of the discharge. The sensor can be located in the discharge box 2, which can realize real-time detection of the degree of closure of the discharge port 8 by the baffle plate 17. When it is detected that the baffle plate 17 completely blocks the discharge port 8, the motor is controlled to stop rotating, thereby maintaining the closed state of the discharge port 8 by the baffle plate 17.

[0019] Furthermore, the rotating rod 5 can be divided into two detachable parts, the lower part of the rotating rod 5 is connected to the output shaft of the first motor 7, and a bearing that cooperates with the upper part of the rotating rod 5 is installed inside the cover 4. The upper part of the rotating rod 5 and the lower part of the rotating rod 5 are connected as one unit by threaded fasteners.

[0020] This detachable design allows operators to easily remove the rotor 5 or agitator 6 when cleaning, maintenance, or replacement is needed, eliminating the need for extensive disassembly of the entire device and significantly reducing maintenance difficulty and costs. Furthermore, the ease of disassembly and assembly facilitates regular cleaning and maintenance, extending the equipment's lifespan and improving its reliability and stability.

[0021] Furthermore, to prevent external moisture from entering the feeding box 2 and the feeding cylinder 3 through the feed pipe 12 and reacting with the fertilizer at the feeding port 8, thereby forming crystals and causing blockage, such as... Figure 6 As shown, the feeding box 2 is equipped with a gate plate 18 that can block the feeding trough 9. The gate plate 18 has a slot 19 that mates with the feeding trough 9. The feeding box 2 has a slide that mates with the gate plate 18. A rack 20 is installed on one side of the gate plate 18. A third motor 21 is installed in the feeding box 2. A gear 22 that meshes with the rack 20 is installed on the output shaft of the third motor 21. When the third motor 21 is started, it can drive the gate plate 18 to move, thereby opening and closing the feeding trough 9.

[0022] The gate plate 18 inside the feeding box 2 is designed to isolate the feeding trough 9 from the guide pipe 12 when no material is being discharged, thus preventing external moisture from affecting the solid fertilizer inside. Furthermore, the gate plate 18 enhances the control over the feeding process. Combined with the opening and closing control of the feeding port 8, this dual control method allows the device to adapt to different fertilization scenarios and crop needs. For example, when fertilization needs to be paused or the fertilization area changed, the feeding port 8 or the feeding trough 9 can be quickly closed to avoid fertilizer waste and misapplication.

[0023] When discharging solid fertilizer, the fertilizer discharging device, upon receiving the batch weight, first opens the gate plate 18, and the stirring blades 6 and the feeding impeller 10 immediately begin to rotate to discharge the fertilizer. The stirring blades 6 crush the material in the feed cylinder 3 and send it to the discharge port 8. Subsequently, the feeding impeller 10 conveys the material from the discharge port 8 into the guide pipe 12. Through the synergistic action of the stirring blades 6 and the feeding impeller 10, fertilizer agglomeration is effectively prevented, and precise discharging is achieved. When the discharging weight approaches the target weight, the stirring blades 6 stop rotating, and the baffle plate 17 closes the discharge port 8. After the discharge port 8 is closed, the feeding impeller 10 continues to operate for 5 seconds to ensure that all the fertilizer in the discharge port 8 is conveyed into the guide pipe 12. After each process, the system automatically calculates the lead time for closing the discharge port 8 based on the error, thereby further reducing the error.

[0024] The various components of this device are compactly arranged, with tight connections between major components such as the support base 1, the feeding box 2, and the material cylinder 3, resulting in a rational overall structure. This compact design not only reduces the device's footprint and saves space resources but also makes transportation and installation more convenient and efficient. Furthermore, the compact structure helps improve the device's stability and anti-interference capabilities, reducing the impact of external factors on its operation and ensuring the smooth progress of the fertilization process.
