Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of water-soluble fertilizer production equipment, and in particular to an automatic mixing device for water-soluble fertilizer. Background Technology
[0002] Water-soluble fertilizer, also known as water-soluble compound fertilizer, is a type of multi-element compound fertilizer that can completely dissolve in water. It dissolves rapidly in water, resulting in higher absorption and utilization rates by plants. It is commonly used in modern agricultural facilities such as drip irrigation, sprinkler irrigation, and foliar spraying to achieve integrated water and fertilizer management, thereby saving water and fertilizer while increasing yield and efficiency. Simply put, water-soluble fertilizer is a highly efficient and precise modern fertilizer, an important production material for the transformation of traditional agriculture to precision agriculture. It's like an IV drip for plants, quickly replenishing them with the precise nutrients they need. Although the unit price is higher, by improving utilization rates, saving labor, and enhancing crop quality, it ultimately brings better economic benefits to growers.
[0003] In the production process of water-soluble fertilizer, various raw materials need to be mixed according to corresponding proportions. In the existing mixing device, the mixing rod can only stir at a fixed height level. This results in the mixing rod only having a good mixing effect on the materials at its corresponding height level, while the mixing effect on materials at a certain height difference from the mixing rod is slightly worse. This has a certain impact on the uniformity of the mixing of materials and thus affects the quality of the finished product. In order to address this issue, this application proposes an automatic mixing device for water-soluble fertilizer to ensure the uniformity of the mixing rod for materials at different levels, thereby guaranteeing the quality of the finished product. Utility Model Content
[0004] To address the above situation and overcome the shortcomings of existing technologies, this utility model provides an automatic water-soluble fertilizer mixing device. The technical solution it provides includes a mixing tank, characterized in that a discharge device is connected to the bottom of the mixing tank; a column is fixedly installed on one side of the mixing tank; two mounting plates arranged vertically opposite each other are fixedly connected to the top of the column; a reciprocating screw arranged vertically is rotatably connected to the opposite ends of the two mounting plates; a drive motor for driving the reciprocating screw is fixedly connected to the upper mounting plate; vertical rods symmetrically arranged about the reciprocating screw are fixedly connected to the opposite ends of the two mounting plates; the middle part of the reciprocating rod is threadedly connected to the reciprocating screw; both ends of the reciprocating rod are slidably connected to the two vertical rods; a horizontal rod is fixedly connected to the reciprocating rod; a mounting base is fixedly connected to the horizontal rod; a mixing rod is rotatably connected to the mounting base; a stirring motor for driving the mixing rod is fixedly connected to the upper end of the mounting base; multiple mixing rods evenly arranged vertically are fixedly connected to the mixing rod; and a reinforcing rod is fixedly connected to both the mounting base and the horizontal rod.
[0005] Preferably, the discharge device includes a discharge pipe that is coaxially and fixedly connected to the bottom of the mixing tank, and a discharge valve is installed on the discharge pipe.
[0006] Preferably, the bottom of the mixing tank is fixedly connected with a plurality of support legs that partially surround its axis, and each support leg is fixedly connected to the lower end of the column with a support, and each support has four connection holes arranged in a rectangular array.
[0007] Preferably, a threaded sleeve that engages with the reciprocating screw is fixedly connected to the middle of the reciprocating rod, and bushings that slide with the vertical rods on their corresponding sides are fixedly connected to both ends of the reciprocating rod.
[0008] The beneficial effects of this utility model are: In use, starting the stirring motor drives the stirring rod to rotate, which in turn rotates the mixing rod on the stirring rod to mix the materials in the mixing tank. Furthermore, starting the drive motor drives the reciprocating screw to rotate, which in turn drives the reciprocating rod to move back and forth along the vertical rod. Consequently, the horizontal rod fixedly connected to the reciprocating rod, as well as the mounting base, stirring rod, and other corresponding components, also move back and forth vertically. As a result, the mixing rod on the stirring rod also moves back and forth vertically. During this vertical reciprocating movement, the mixing rod can mix materials at different heights, ensuring uniform mixing and thus guaranteeing the quality of the finished product.

[0014] The following is in conjunction with the appendix Figure 1-4The specific embodiments of this utility model will be described in further detail.
[0015] In the first embodiment, the technical solution is as follows: When this application is in use, starting the stirring motor 12 can drive the stirring rod 11 to rotate, and the mixing rod 13 on the stirring rod 11 will also rotate and mix the materials in the mixing tank 1. Furthermore, starting the provided drive motor 6 will drive the reciprocating screw 5 to rotate, and the rotation of the reciprocating screw 5 will drive the reciprocating rod 8 to move back and forth along the vertical rod 7. As a result, the horizontal rod 9 fixedly connected to the reciprocating rod 8, as well as the mounting base 10, stirring rod 11, and other corresponding components will also move back and forth vertically. Consequently, the mixing rod 13 on the stirring rod 11 will also move back and forth vertically. During the process of moving back and forth vertically, the mixing rod 13 can mix materials at different height levels, ensuring uniform mixing of materials and thus guaranteeing the quality of the finished product.
[0016] In Example 2, based on Example 1, specifically, in use, both the bottom of the column 3 and the support leg 17 are provided with supports 18. The column 3 and the mixing tank 1 can be fixed in a suitable position in the workshop by using expansion bolts with the connecting holes 19 on the supports 18. When mixing the raw materials, the raw materials are added to the mixing tank 1 according to the ratio. The stirring motor 12 on the mounting base 10 is started, which drives the stirring rod 11 to rotate. The stirring rod 11, along with the mixing rod 13, will rotate together, thus mixing the materials through the mixing rod 13. Furthermore, to ensure that the mixing rod 13 can evenly mix materials at various height levels, the drive motor 6 on the mounting plate 4 is also started. The drive motor 6 drives the reciprocating screw 5 to rotate, which in turn drives the reciprocating rod that is threadedly engaged with the threaded sleeve 20. 8. The reciprocating rod 8 is restricted by the sliding connection between the bushing 21 and the vertical rod 7. Therefore, driven by the reciprocating screw 5, the reciprocating rod 8 will move vertically back and forth along the vertical rod 7. Consequently, the horizontal rod 9, which is fixedly connected to the reciprocating rod 8, along with the mounting base 10, will also move vertically back and forth. The stirring rod 11 and the mixing rod 13, which are connected to the mounting base 10, will also move vertically back and forth. As the mixing rod 13 moves vertically back and forth, it can mix materials at different heights to ensure uniform mixing and thus guarantee the quality of the finished product.
[0017] In Example 3, based on Example 2, to ensure the normal operation of the crossbar 9 and the mounting base 10 and to ensure their supporting strength, a reinforcing bar 14 is provided to enhance their strength and ensure normal use. After the materials are mixed, the discharge valve of the discharge device 2 can be opened to discharge the materials from the discharge pipe.
