Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery, and in particular to a fertilizer mixing device. Background Technology
[0002] In modern agricultural production, fertilization in field farming is one of the key aspects of improving crop yield and quality. A proper fertilizer ratio not only provides the nutrients needed for crop growth but also improves soil structure and promotes healthy crop development. Currently, to quantify fertilizer application, different types of fertilizers are typically mixed and weighed according to proportions using fertilizer mixing devices. However, traditional fertilizer mixing devices have significant shortcomings in practical applications, particularly in terms of equipment mobility and ease of operation, which fail to meet the needs of modern agriculture.
[0003] Traditional batching devices typically have a fixed hopper height, resulting in a high center of gravity and large size. This makes them susceptible to terrain limitations during field movement, leading to difficulties in movement and poor stability. For example, when transferring equipment between different plots, a fixed-height hopper may hinder its mobility or increase the risk of tipping due to instability, severely impacting operational efficiency. Furthermore, the fixed structure of the hopper occupies a significant amount of space during transportation, increasing both costs and difficulties.
[0004] In existing technologies, although some devices are equipped with casters, the lack of an adjustable-height feed cylinder structure prevents the effective lowering of the equipment's center of gravity or reduction in size, making it difficult to guarantee mobility and stability. Therefore, how to improve the mobility of fertilizer application devices through structural innovation to achieve convenient and efficient field operations has become an urgent technical problem to be solved. Utility Model Content
[0005] The purpose of this utility model is to solve the above-mentioned technical problems and provide a fertilizer batching device. The present application is to set the material cylinder of the fertilizer batching device to be height-adjustable, so that the height of the material cylinder can be lowered when not batching, thereby reducing the height and center of gravity of the equipment and improving the flexibility of the fertilizer batching device.
[0006] A fertilizer dispensing device includes a material cylinder, a switch assembly, a lifting assembly, a weighing assembly, and a base. The upper part of the material cylinder has multiple partitioned receiving cavities, and the lower part has a collecting cavity. The receiving cavities are open at the top and bottom, and fertilizer is added into the receiving cavities through the upper opening. The number of switch assemblies is the same as the number of receiving cavities, and they are located at the lower opening of the receiving cavities. The lower opening of the receiving cavities communicates with the collecting cavity, and the collecting cavity has a fertilizer outlet. The material cylinder is mounted on the base in a height-adjustable manner via the lifting assembly. The weighing assembly is mounted on the base, and the outlet is positioned opposite the weighing assembly. During weighing, the material cylinder is raised by the lifting assembly, so that the material cylinder and the weighing assembly on the base form a weighing space. During storage, the material cylinder is lowered by the lifting assembly, so that the material cylinder rests against the weighing assembly on the base.
[0007] According to the fertilizer dispensing device of this application, the material cylinder is provided with multiple receiving cavities, which can be used to hold different fertilizers. When dispensing is required, the corresponding receiving cavity can be opened by turning on the switch assembly, allowing the fertilizer to fall naturally into the collecting cavity and then onto the weighing assembly for weighing. When the weight of that type of fertilizer is sufficient, the corresponding switch assembly is closed, and then the switch assemblies for other types of fertilizer are turned on to allow them to fall onto the weighing assembly for weighing, thereby completing the dispensing of fertilizer. Because a lifting assembly is provided, after dispensing is completed, the material cylinder can be lowered so that the material cylinder rests against the weighing assembly on the base. This not only lowers the height and center of gravity of the equipment, reducing the risk of tipping over due to instability when moving the fertilizer dispensing device, but also makes it convenient for the user to continue adding fertilizer into the receiving cavity through the upper opening of the receiving cavity.
[0008] Furthermore, the lifting assembly includes a power element and multiple lifting rod elements. The power element drives the multiple lifting rod elements to lift and lower. The power element is a pneumatic pump or a hydraulic pump, and the lifting rod elements are either pneumatic lifting rods or hydraulic lifting rods.
[0009] Furthermore, the weighing component is annular, with a connecting interface formed in the middle. The outer shell of the collecting cavity is funnel-shaped, and the discharge port is located at the lowest point of the collecting cavity, so that the discharge port is inserted into the connecting interface during storage. This insertion method between the discharge port and the connecting interface allows the material cylinder to rest more stably against the weighing component on the base.
[0010] Furthermore, the switching assembly includes a baffle and a linear motor. One end of the linear motor is mounted on the outer shell of the material cylinder, and the other end extends into the material cylinder and is connected to the baffle, so that the baffle opens and closes the lower opening of the receiving cavity under the drive of the linear motor.
[0011] Furthermore, the bottom surface of the accommodating cavity is provided with an inclined surface, which slopes towards the lower opening of the accommodating cavity. The lower part of the inclined surface is provided with a mounting cavity for the connection and movement of the motor shaft and the baffle. The inclined surface not only allows the fertilizer in the accommodating cavity to slide smoothly towards the lower opening, but also provides space for the connection and movement of the motor shaft and the baffle.
[0012] Furthermore, it also includes a main control component, which is mounted on the base and electrically connected to the switch component, lifting component, and weighing component. This allows for convenient control of the operation of the switch component, lifting component, and weighing component via the main control component.
[0013] Furthermore, the lower surface of the base is equipped with casters to facilitate the movement of the fertilizer dispensing device. Attached Figure Description

[0019] The present invention relates to a fertilizer mixing device, which is described in conjunction with the accompanying drawings.
[0020] like Figures 1 to 5The fertilizer dispensing device shown includes a material cylinder 1, a switch assembly 2, a lifting assembly 3, a weighing assembly 4, and a base 5. The material cylinder 1 has multiple partitioned receiving cavities 11 at its upper part and a collecting cavity 12 at its lower part. Each receiving cavity 11 has an upper and lower opening 112. Fertilizer is added into the receiving cavity 11 through the upper opening 111. The number of switch assemblies 2 is the same as the number of receiving cavities 11, and they are located at the lower opening 112 of each receiving cavity 11. The lower opening 112 of each receiving cavity 11 communicates with the collecting cavity 12. The collecting cavity 12 is provided with a fertilizer outlet 121. The material cylinder 1 is movably mounted on the base 5 via a lifting assembly 3. The weighing assembly 4 is mounted on the base 5, and the outlet 121 is positioned opposite the weighing assembly 4. During weighing, the material cylinder 1 is raised via the lifting assembly 3, creating a weighing space between the material cylinder 1 and the weighing assembly 4 on the base 5. A container filled with fertilizer can be placed on the weighing assembly 4 within this space, and the fertilizer from the material cylinder 1 is weighed simultaneously. Multiple receiving cavities 11 are provided to hold different fertilizers. When mixing is required, the corresponding receiving cavity 11 can be opened by turning on the switch assembly 2, allowing the fertilizer to fall naturally into the collecting cavity 12 and then onto the weighing assembly 4 for weighing. Once the weight of that type of fertilizer is sufficient, the corresponding switch assembly 2 is closed. Then, the switch assemblies 2 for other types of fertilizers are turned on to allow them to fall onto the weighing assembly 4 for weighing, thus completing the fertilizer mixing process. The amount of fertilizer that falls between the completion of weighing and the closing of the switch assembly 2 is recorded. The impact of the ingredients can be ignored, and it can also be set to turn off the switch component 2 in advance to compensate for the amount of fertilizer that falls, so as to make the fertilizer ratio more accurate. When storing, the material cylinder 1 is lowered by the lifting component 3 so that the material cylinder 1 rests on the weighing component 4 of the base 5. This not only lowers the height and center of gravity of the equipment, but also reduces the risk of tipping due to instability when transferring the fertilizer mixing device. It also makes it convenient for the user to continue to add fertilizer to the receiving cavity 11 through the upper opening 111 of the receiving cavity 11.
[0021] like Figure 1 As shown, the lifting assembly 3 includes a power element 31 and multiple lifting rod elements 32. The power element 31 drives the multiple lifting rod elements 32 to lift and lower. The power element 31 is a pneumatic pump or a hydraulic pump, and the lifting rod elements 32 correspond to pneumatic lifting rods or hydraulic lifting rods. The power element 31 and the multiple lifting elements are connected by a pipe and valve structure (not shown in the figure). Preferably, it includes a diversion and combination valve and a speed control valve. After the main pipe is led out from the power element 31, it is evenly divided into multiple branch pipes by the diversion and combination valve. The branch pipes are connected to the lifting rod elements 32, so that the multiple lifting rod elements 32 can lift and lower evenly. A speed control valve is set on each branch pipe to finely adjust the flow rate of each branch and compensate for mechanical errors.
[0022] Multiple lifting rod elements 32 are symmetrically arranged on both sides of the base 5. The attached drawings of this application show six lifting rod elements 32, three on each side, and as shown... Figure 1 As shown, the lifting rod element 32 is positioned outwards, allowing for a larger space between the two lifting rod elements 32, thus enabling the fertilizer that has been prepared to be smoothly removed from between the lifting rod elements 32.
[0023] like Figures 1 to 5 As shown, the weighing component 4 is annular, with a connecting interface 51 formed in the middle of the weighing component 4. The outer shell of the collecting cavity 12 is funnel-shaped, and the discharge port 121 is located at the lowest point of the collecting cavity 12. When storing, the discharge port 121 is inserted into the connecting interface 51. The way the discharge port 121 is inserted into the connecting interface 51 can make the material cylinder 1 more stably abut against the weighing component 4 of the base 5.
[0024] like Figure 5 As shown, the weighing assembly 4 includes a panel 41 and a weighing circuit board 42. The panel 41 is made of acrylic, which is not easily broken and can better bear weight. The top surface of the acrylic panel 41 protrudes relative to the top surface of the base 5 to avoid the top surface of the base 5 affecting the weighing. The weighing circuit board 42 is provided with four evenly arranged weighing sensors 421 to measure the weight of the fertilizer. The base 5 is provided with a mounting groove 53, and the side wall of the mounting groove 53 is provided with a limiting post 531. The weighing circuit board 42 is provided with a corresponding limiting notch 422. The limiting post 531 and the limiting notch 422 cooperate to limit the weighing circuit board in the mounting groove 53, preventing the weighing circuit board from rotating in the mounting groove 53.
[0025] like Figure 2 and Figure 3 As shown, the switch assembly 2 includes a baffle 22 and a linear motor 21. The linear motor 21 includes a main unit 211, a motor shaft 212, and a connector 213. The main unit 211 is mounted on the outer shell of the material cylinder 1, the motor shaft 212 extends into the material cylinder 1, and the connector 213 is slidably mounted on the motor shaft 212. The connector 213 is connected to the baffle 22 by screws or welding, so that the baffle 22 opens and closes the lower opening 112 of the receiving cavity 11 under the drive of the linear motor 21.
[0026] like Figure 2 and Figure 3As shown, the bottom surface of the accommodating cavity 11 is provided with an inclined surface 113, which is inclined toward the lower opening 112 of the accommodating cavity 11. The lower part of the inclined surface 113 is provided with a mounting cavity 13 for connecting and moving the motor shaft 212 and the baffle 22. The inclined surface 113 can not only allow the fertilizer in the accommodating cavity 11 to slide smoothly toward the lower opening 112, but also provide space for the motor shaft 212 and the baffle 22 to connect and move. The bottom of the mounting cavity 13 is a sliding groove 131, which can support the baffle 22 and allow the baffle 22 to move under the drive of the linear motor 21.
[0027] like Figure 5 As shown, it also includes a main control component, which is mounted on the base 5. The main control component is electrically connected to the switch component 2, the lifting component 3, and the weighing component 4 respectively, so as to facilitate the control of the operation of the switch component 2, the lifting component 3, and the weighing component 4 through the main control component.
[0028] The main control component includes a main control circuit board 6 and a touch screen display 61. The main control circuit board 6 is electrically connected to the touch screen display 61, the linear motor 21, the power element 31, and the weighing circuit board 42. The fertilizer ratio can be set through the touch screen display. The main control circuit board 6 obtains the weighing data through the weighing circuit board 42, thereby controlling the start and stop of the linear motor 21, so that the fertilizer of the corresponding ratio falls onto the weighing component 4. The start and stop of the power element 31 can also be controlled through the main control circuit board 6 and the touch screen display 61, so that the material cylinder 1 can be raised and lowered relative to the base 5.
[0029] The lower surface of the base 5 is equipped with casters 52, which facilitates the movement of the fertilizer mixing device.
[0030] The main control component, switch component 2, lifting component 3, and weighing component 4 are all commercially available accessories. For example, the lifting rod can be raised and lowered synchronously by using an SMC air pump, Parker lifting rod, and Festo synchronization valve. Weighing data can be obtained by using an HBM sensor and Arduino ADC chip circuit board. The entire system can be controlled by using a Weinview MT8102iE touch screen and a Raspberry Pi 4 Model B main control circuit board.
[0031] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
