Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to a soil amendment fertilizer mold device. Background Technology

[0002] Soil is the material basis and environmental condition upon which plants depend for survival. It directly affects the health of plant growth and the landscape and ecological benefits of urban green spaces. Urban soil has the following characteristics: significant temporal and spatial variability; chaotic soil profile structure and developmental morphology; abundant human-made additives; altered soil physical structure; disrupted soil nutrient cycling and soil biological activity; and high levels of pollution. Urban street green space soil has developed under the long-term disturbance of human activities or the unique environmental background of cities. It presents obstacles such as unsuitability for plant growth and incompatibility with certain greening schemes, necessitating its improvement. Therefore, soil improvement has become one of the most important aspects of green space soil management.

[0003] In existing technologies, using sludge carbonization products to produce pellet fertilizer is an effective means of soil improvement: these pellet fertilizers can adsorb heavy metals in the soil, achieving soil remediation and purification. Furthermore, their shape facilitates insertion into the soil, enabling precise fertilization, reducing fertilizer loss, and improving utilization. However, the mold devices used in existing pellet fertilizer production have significant limitations. Most molds are of a split structure, making the processes of raw material filling, extrusion molding, and demolding cumbersome. Moreover, the resulting pellet fertilizer exhibits poor structural consistency, making it difficult to meet the needs of large-scale production and hindering the widespread application of this type of pellet fertilizer in soil improvement.

[0004] In response to the problems of low production efficiency and poor molding quality of existing fertilizer bar molds, there is an urgent need for a mold device that can efficiently produce soil-improving fertilizer bars. Utility Model Content

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a soil improvement fertilizer stick mold device, which can be used to make fertilizer sticks and insert the formed fertilizer sticks into the soil to achieve precise fertilization and improve fertilizer utilization.

[0006] The technical solution adopted by this utility model is: a soil improvement bar fertilizer mold device, including a molding base, a molding cylinder arranged vertically at the upper end of the molding base, an extrusion mold column that can move up and down inside the molding cylinder, and a pressing space is formed between the outer periphery of the extrusion mold column and the inner wall of the molding cylinder; the upper end of the extrusion mold column is provided with a pressure part, and the pressure part is connected to a plurality of guide columns arranged vertically and located outside the molding cylinder.

[0007] The mold device provided in this technical solution can process the raw materials of granulated fertilizer. When in use, the various raw materials of granulated fertilizer are mixed and added into the molding cylinder. By applying downward pressure in the pressurizing part, the extrusion die column moves vertically and extrudes the raw materials of granulated fertilizer during the movement. The raw materials of granulated fertilizer are evenly extruded into the mold space for molding. When the extrusion die column moves upward and separates from the molding cylinder, the raw materials of granulated fertilizer are extruded into a hollow cylindrical structure. The hollow area inside can be filled with fertilizer such as mixed organic granules, thereby improving the molding efficiency and quality of granulated fertilizer.

[0008] Preferably, the molding base is provided with a discharge port arranged directly opposite to the molding space, and the discharge port is provided with a detachable sealing block.

[0009] Preferably, the guide post includes a guide cylinder, the lower end of which is fixedly connected to the molding base, and a guide rod is slidably mounted on the upper end of the guide cylinder, the upper end of which is fixedly connected to the pressure part.

[0010] Preferably, the upper end of the forming cylinder is provided with a circumferentially arranged positioning part, and the bottom of the pressurizing part is provided with a positioning groove arranged opposite to the positioning part.

[0011] The beneficial effects of this invention are as follows: By combining the forming cylinder and the extrusion die, the mixed fertilizer raw materials are directly added to the forming cylinder. The pressure unit drives the extrusion die to move vertically, achieving rapid extrusion molding. This simplifies the raw material filling, molding, and demolding processes, significantly reduces production steps, and substantially improves fertilizer production efficiency, making it suitable for large-scale production. This invention solves the problems of low production efficiency and poor quality in existing fertilizer production by optimizing the mold structure; therefore, it has high practical value.

Detailed Implementation

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0019] Example 1

[0020] like Figure 1 and Figure 2 As shown in the figure, a specific embodiment of this utility model provides a soil amendment bar fertilizer mold device, including a molding base 100, a molding cylinder 200 arranged vertically at the upper end of the molding base 100, an extrusion die column 300 that can move up and down inside the molding cylinder 200, and a molding space 400 formed between the outer periphery of the extrusion die column 300 and the inner wall of the molding cylinder 200; a pressure part 500 is provided at the upper end of the extrusion die column 300, and the pressure part 500 is connected to a plurality of guide columns 600 arranged vertically and located outside the molding cylinder 200.

[0021] like Figure 1 and Figure 2 As shown, with the above settings, the mold device provided in this embodiment can perform molding processing on the raw material of the fertilizer bar. When in use, the raw material of the fertilizer bar is mixed and added into the molding cylinder 200. By applying downward pressure in the pressurizing part 500, the extrusion die 300 moves vertically and extrudes the raw material of the fertilizer bar during the movement, so that the raw material of the fertilizer bar is evenly extruded into the mold space 400 for molding. When the extrusion die 300 moves upward and separates from the molding cylinder 200, the raw material of the fertilizer bar is extruded into a hollow cylindrical structure to obtain the fertilizer bar shell 810. The hollow area inside can be filled with fertilizer such as organic mixed granules, thereby improving the molding efficiency and quality of the fertilizer bar.

[0022] like Figure 1 and Figure 2As shown, in this design, the compression space 400 formed by the outer periphery of the extrusion die 300 and the inner wall of the forming cylinder 200 ensures that the raw material is uniformly extruded. The formed fertilizer bar is a hollow cylindrical shape with high structural consistency. Simultaneously, the internal hollow area can be precisely filled with organic granules and other fertilizers, enhancing the nutrient supply capacity of the fertilizer bar and improving soil improvement. In practical applications, this device can be used manually to apply pressure to the pressurizing section 500, or it can be used in conjunction with a pressure device, such as a cylinder or hydraulic cylinder, utilizing its piston structure to connect with the pressurizing section 500, thereby applying pressure to the pressurizing section 500. The aforementioned pressure device adopts existing technical structures and will not be elaborated upon here.

[0023] like Figure 1 and Figure 2 As shown, the molding base 100 has a discharge port arranged directly opposite the molding space 400, and the discharge port is equipped with a detachable sealing block 700. The design of the discharge port and the detachable sealing block 700 of the molding base 100 facilitates the quick removal of the molded rod and is easy to operate. The sealing block 700 can be installed by screwing or snapping, which will not be described in detail here.

[0024] like Figure 1 and Figure 2 As shown, in this embodiment, the guide post 600 provides stable guidance for the vertical movement of the extrusion die post 300, preventing deviation during extrusion and ensuring molding accuracy. The guide post 600 structure includes a guide cylinder 610, the lower end of which is fixedly connected to the molding base 100, and a guide rod 620 slidably mounted on the upper end of the guide cylinder 610. The upper end of the guide rod 620 is fixedly connected to the pressure part 500. In this way, the guide rod 620 and the guide cylinder 610 can be interlocked, allowing the guide rod 620 to move stably along the guide cylinder 610, ensuring molding accuracy. In addition, the upper end of the molding cylinder 200 is provided with a circumferentially arranged positioning part 210, and the bottom of the pressure part 500 is provided with a positioning groove 510 arranged opposite to the positioning part 210. The positioning part 210 at the upper end of the molding cylinder 200 and the positioning groove 510 at the bottom of the pressure part 500 cooperate to further improve the stability of the pressure process.

[0025] Example 2

[0026] The specific steps for producing fertilizer using this device are as follows:

[0027] Step 1. Mix sludge carbonized material (particle size range of 0.5-5mm, concentrated in the range of 1-2.5mm, accounting for more than 80%) with organic fertilizer (municipal sludge compost, garden green waste compost, kitchen waste fertilizer, humic acid, particle size less than 0.5mm) in a ratio of 6:4. After uniform mixing, obtain the 820 rod fertilizer core.

[0028] Step 2. The outer layer material of the fertilizer bar uses sheep manure, oilseed cake, and sludge as organic fertilizer materials, and ferrous sulfate, calcium magnesium phosphate, and nitrogen-phosphorus-potassium compound fertilizer as inorganic fertilizer materials, with an organic-inorganic mixing ratio of 5:5. Attapulgite is used as the binder, with an addition ratio of 3%. After the outer shell material of the fertilizer bar is fully mixed with water, it is added to the soil improvement fertilizer bar mold device provided in Example 1. The raw material is extruded and shaped into a hollow fertilizer bar shell 810 by the extrusion die column. Then, the fertilizer bar core 820 from Step 1 is added into the fertilizer bar shell 810 and the opening of the fertilizer bar shell is sealed, finally obtaining the finished fertilizer bar 800. The finished fertilizer bar 800 is usually produced with the following specifications: length 20-30cm, diameter 5-10cm, outer layer thickness 1-3cm, and inner core diameter of organic mixed granules 3-6cm.

[0029] In the experiment, the applicant applied fertilizer sticks to improve the soil for tree planting. The specific fertilization method was as follows: four fertilizer stick application points were evenly distributed around the drip line of the tree canopy. Holes were drilled using a soil drilling machine, with a depth of at least 55 cm. The fertilizer sticks were placed into the holes and covered with soil. An equal amount of compound fertilizer (N:P2O5:K = 15:15:15) was applied using the same method, with no fertilizer application serving as a control. Plant physiological indicators were measured, and the experimental results are shown in Table 1.

[0030]

[0031] Table 1

[0032] As shown in the table above, fertilizer can not only improve the physical properties of the soil, increase soil aeration, promote the growth of plant roots, increase the organic matter content and available nutrients in the soil, but also improve leaf yellowing.

[0033] 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 the 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 or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
