Abstract
Description
Technical Field
[0001] This utility model relates to the field of nutrient soil preparation technology, and in particular to a nutrient soil packaging bagger. Background Technology
[0002] Nutrient bag seedling cultivation is an effective measure to increase seedling yield and save production costs. When cultivating small-sized tree seedlings or herbaceous seedlings on a large scale, if the operations of filling soil and moving seedlings are done entirely by hand, it is time-consuming, labor-intensive, and inefficient. Nutrient soil packaging bag filling devices can reduce labor intensity, improve filling efficiency, and package multiple nutrient bags at once, which has been accepted by the majority of flower growers.
[0003] In the use of existing soil loading devices, the nutrient bags used are mostly made of thin plastic, which makes them prone to shape changes. In particular, the uneven force during the filling of nutrient soil can easily cause deformation, which not only affects the appearance but also makes them prone to shrinking and obstructing the filling opening, resulting in insufficient filling of soil to meet the target amount and affecting the filling effect. Existing soil loading devices also lack the ability to keep the nutrient bags open. Utility Model Content
[0004] This utility model provides a soil filling device for nutrient soil dispensing bags. During the nutrient soil dispensing process, the nutrient bag is kept in an open state, so that the dispensing opening will not be blocked due to deformation and shrinkage, thus preventing insufficient soil from being dispensed to meet the target amount, thereby improving the dispensing effect. It can also maintain a certain gap between the dispensing mold and the nutrient bag, making it easy to separate the soil filling device from the nutrient bag after dispensing.
[0005] The purpose and effect of this utility model of a nutrient soil dispensing bagger are achieved by the following specific technical means: The nutrient soil dispensing bagger includes a main body, a dispensing mold disposed inside the main body, a dispensing port disposed through the dispensing mold, a dispensing plate disposed at the top of the dispensing mold and located inside the main body, a feed inlet disposed through the dispensing plate, and a grip plate disposed at the top of the main body.
[0006] A demolding assembly is disposed inside the dispensing mold and includes an inflation tube and an isolation layer. The isolation layer is disposed on the inner wall of the dispensing port, and the inflation tube is disposed at the top of the isolation layer and located at the top of the dispensing mold.
[0007] The expansion assembly is located inside the feed inlet and includes an installation strip and a retaining ring. Each installation strip is located inside the feed inlet and each installation strip is provided with a retaining ring.
[0008] Preferably, the feed inlet is a circular hole, and the feed inlets are arranged in a rectangular array.
[0009] Preferably, each of the fixing rings is circular in shape, and each fixing ring has a vertical strip running through it. The outer diameter of each vertical strip is adapted to the inner diameter of the corresponding fixing ring.
[0010] Preferably, each of the vertical strips is provided with an abutment plate at its bottom end, and each abutment plate is made of rubber.
[0011] Preferably, each of the abutment plates is provided with an elastic strip at its top, and each group of elastic strips is arranged in a circular array, with the top of each elastic strip being fixedly connected to the bottom of the fixing ring.
[0012] Preferably, the dispensing port is a rectangular hole, the dispensing ports are arranged in a rectangular array, and the dispensing mold is a grid.
[0013] Preferably, each of the isolation layers is U-shaped, each of the isolation layers is hollow inside, each of the isolation layers is made of elastic polyurethane, and the external dimensions of each isolation layer are adapted to the internal dimensions of the corresponding dispensing port.
[0014] Preferably, the inflation tube is mesh-shaped, and the shape and size of the inflation tube are adapted to the shape and size of the packaging mold. The inflation tube is a hollow mesh-shaped pipe.
[0015] Preferably, an air bladder is provided through the side wall of the soil loading device body, and the air bladder is located inside the soil loading device body and communicates with the inside of the inflation tube.
[0016] Preferably, an air outlet is provided through the side wall of the soil loading device body, and the air outlet is located inside the soil loading device body and communicates with the inside of the air filling pipe.
[0017] Beneficial effects:
[0018] 1. With the set expansion component, the dispensing plate is installed on the top of the dispensing mold, and the abutment plate contacts the bottom of the nutrient bag inside the dispensing mold. The vertical strip is squeezed upward, and the elastic strip is bent and expanded in all directions. During the dispensing of nutrient soil, the nutrient bag is kept in an expanded state. The nutrient bag will not deform and shrink and block the dispensing port, so that the amount of soil dispensed is not enough to reach the target amount, thus improving the dispensing effect.
[0019] 2. With the separation component, air is blown into the isolation layer through the air bladder before the nutrient bag is put into the dispensing mold, so that the dispensing mold and the nutrient bag maintain a certain gap. After dispensing, the air outlet is opened to release the isolation layer, so that the nutrient bag does not come into contact with the soil loading device, which facilitates the separation of the soil loading device and the nutrient bag after dispensing.

The vertical strip 903 is squeezed upward, and the elastic strip 904 is bent and expanded in all directions, so that the nutrient bag is also expanded. During the dispensing of nutrient soil, the nutrient bag is kept in an expanded state.
[0037] Second Embodiment
[0038] As attached Figure 1 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 and attached Figure 8 As shown: Demolding component 7, which is set inside the dispensing mold 5, includes an inflation tube 701 and an isolation layer 702. The isolation layer 702 is set on the inner wall of the dispensing port 6, and the inflation tube 701 is set at the top of the isolation layer 702 and located at the top of the dispensing mold 5. The dispensing port 6 is a rectangular hole, and the dispensing ports 6 are arranged in a rectangular array. The dispensing mold 5 is a grid. Before dispensing, the nutrient bag is first put into the dispensing mold 5.
[0039] Each isolation layer 702 is U-shaped, hollow inside, and made of elastic polyurethane. The external dimensions of each isolation layer 702 are adapted to the internal dimensions of the corresponding dispensing port 6. Air is blown into the isolation layer 702 by the air inflator 4, causing the isolation layer 702 to expand and come into contact with the nutrient bag, thus maintaining a certain gap between the dispensing mold 5 and the nutrient bag.
[0040] The inflation tube 701 is mesh-shaped, and its shape and size are compatible with the shape and size of the packaging mold 5. The inflation tube 701 is a hollow mesh-shaped pipe that connects to each isolation layer 702. Air is blown into or released from the isolation layer 702 through the inflation tube 701.
[0041] An air bladder 4 is provided through the side wall of the soil loading device body 1. The air bladder 4 is located inside the soil loading device body 1 and is connected to the inside of the air inflator 701. The air bladder 4 controls the air to be blown into the isolation layer 702.
[0042] An air outlet 3 is provided through the side wall of the soil loading device body 1. The air outlet 3 is located inside the soil loading device body 1 and is connected to the air filling pipe 701. The air outlet 3 controls the release of air inside the isolation layer 702.
[0043] Working principle: Before dispensing, the nutrient bag is placed inside the dispensing mold 5. The dispensing plate 2 is installed at the top of the dispensing mold 5. The expanding component 9 passes through the dispensing opening 6, and the abutment plate 905 contacts the bottom of the nutrient bag inside the dispensing mold 5. The vertical strip 903 is squeezed upward, and the elastic strip 904 is bent and expanded in all directions, thus expanding the nutrient bag as well. During the dispensing process, the nutrient bag is kept in an expanded state, preventing it from deforming and shrinking to block the dispensing opening 6 and thus ensuring that the dispensed soil does not meet the target requirements. To improve the scalar quantity and packaging effect, before the nutrient bag is placed into the packaging mold 5, air is blown into the isolation layer 702 through the air inflator 4. The isolation layer 702 expands and contacts the nutrient bag, keeping a certain gap between the packaging mold 5 and the nutrient bag. Nutrient soil is then filled into the packaging plate 2, and the nutrient soil is packaged into the nutrient bag through the feed port 8 and the packaging port 6. After packaging is completed, the air outlet 3 is opened to release the isolation layer 702, so that the nutrient bag does not contact the soil filling device, making it easy to separate the soil filling device from the nutrient bag after packaging is completed.
