[0002] When selecting potting substrates, water retention, air permeability, and drainage should be given priority. Different substrates can be mixed to meet the growth requirements of specific plants. When supplementing nutrients to potted plants, some loose materials, such as rotten sawdust and coconut coir, are added to the potted plants. During the production process of loose materials, the loose materials need to be bagged.

[0003] Before bagging, weighing is required. The current measurement methods used in the market are mainly: ① weighing with a hopper scale, which is different from the target volume measurement method; ② adjusting the volume of the container, but this method has a slow volume adjustment speed, and the feeding is prone to cause material accumulation, making it difficult to feed and having a slow speed. Therefore, when weighing loose materials, due to the fluffiness of the loose materials and their large volume, it is inconvenient to weigh the loose materials when bagging the materials.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Embodiment 1: Refer to Figures 1-4 , a volumetric scale for loose material bag weighing, including a support 3, a plurality of support legs 4 are fixedly connected to both sides of the support 3, a blanking bin 1 is fixedly connected to the upper end of the support 3, a level gauge 2 for detecting the height of the material is connected to the blanking bin 1, a conveying mechanism 10 is fixedly connected to the bottom end of the support 3, a first pressing mechanism 5, a second pressing mechanism 6 and a third pressing mechanism 7 are sequentially connected along the length of the blanking bin 1, the first pressing mechanism 5, the second pressing mechanism 6 and the third pressing mechanism 7 have the same structure, and the distances between the first pressing mechanism 5, the second pressing mechanism 6, the third pressing mechanism 7 and the upper end of the conveying mechanism 10 decrease sequentially. The bottom end of the support 3 is communicated with a discharge hopper 8, and an opening and closing mechanism 9 for controlling the material to enter the discharge hopper 8 is connected to the support 3.

[0023] Working process:

[0024] Pour the material into the blanking bin 1, the level gauge 2 detects the height of the material in the blanking bin 1 to prevent the material from falling from the upper side of the blanking bin 1. The material in the blanking bin 1 falls on the conveying mechanism 10, and the support 3 limits both sides of the conveying mechanism 10 to prevent the material from falling from the side of the conveying mechanism 10;

[0025] Meanwhile, the first pressing mechanism 5, the second pressing mechanism 6, and the third pressing mechanism 7 are powered on and started. After the first pressing mechanism 5, the second pressing mechanism 6, and the third pressing mechanism 7 are started, they sequentially extrude the materials on the upper end of the conveying mechanism 10. While the conveying mechanism 10 conveys the materials, it also supports the materials. During the conveying process of the materials, they are sequentially extruded by the first pressing mechanism 5, the second pressing mechanism 6, and the third pressing mechanism 7, reducing the gap between the materials. After the materials are pressed tightly, the opening and closing mechanism 9 is opened. After the opening and closing mechanism 9 is opened, the materials enter the discharge hopper 8. During the conveying by the conveying mechanism 10, there will be no material accumulation. The materials are released from the discharge hopper 8. After being pressed by the third pressing mechanism 7, the thickness of the materials is certain, and the conveying speed of the conveying mechanism 10 is certain. According to the conveying speed of the materials and the thickness of the materials, the volume of the materials discharged from the discharge hopper 8 is obtained, which is convenient for weighing the materials.

[0026] Embodiment 2: When the first pressing mechanism 5, the second pressing mechanism 6, and the third pressing mechanism 7 press and laminate the materials, some materials are likely to wind around the second pressing mechanism 6. After too much material winds around the second pressing mechanism 6, it will affect the pressing effect on the materials. Refer to Figures 2-3 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that the second pressing mechanism 6 includes a reduction gear 61. The reduction gear 61 is fixedly connected to the bracket 3. A driving motor 62 is connected to the reduction gear 61. The output end of the reduction gear 61 is fixedly connected with a rotating shaft 63. One end of the rotating shaft 63 extends into the bracket 3. Two parallel fixed plates 64 are connected to the rotating shaft 63. A number of rollers 65 are equidistantly connected between the two fixed plates 64 along the axial center line direction. The rollers 65 are located within the bracket 3. There is a spacing between adjacent two rollers 65. After the driving motor 62 is started, it drives the reduction gear 61 to work. The reduction gear 61 drives the rotating shaft 63 to rotate. The rotating shaft 63 drives the fixed plate 64 to rotate. The fixed plate 64 drives the rollers 65 to rotate. After the rollers 65 rotate, they roll-press the conveyed materials, reducing the gap between the materials. Some materials wind around the rollers 65. During the rotation of the rollers 65, the materials on the rollers 65 fall from the spacing, thereby reducing the winding of the materials on the rollers 65 and maintaining the pressing effect on the materials.

[0027] Embodiment 3: When preventing the materials from entering the discharge hopper 8, the materials cannot be blocked quickly. Refer to Figures 2-3, as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that the opening and closing mechanism 9 includes a connecting shaft 93. The connecting shaft 93 is rotatably connected to the bracket 3. One end of the connecting shaft 93 extends into the bracket 3 and is fixedly connected with two parallel second connecting plates 94. One end of each of the two parallel second connecting plates 94 is fixedly connected with a baffle 95. An anti-corrosion layer is sprayed on the baffle 95. The baffle 95 cooperates with the bracket 3. A hydraulic cylinder 91 is rotatably connected to the bracket 3. The output end of the hydraulic cylinder 91 is rotatably connected with a first connecting plate 92. The first connecting plate 92 is fixedly connected to the connecting shaft 93. When the material enters the discharge hopper 8, the telescopic end of the hydraulic cylinder 91 moves upward. The telescopic end of the hydraulic cylinder 91 pulls the first connecting plate 92. The first connecting plate 92 drives the connecting shaft 93 to rotate. The connecting shaft 93 drives the baffle 95 to rotate upward through the second connecting plate 94. After the baffle 95 rotates upward, the discharge hopper 8 is opened, and the material enters the discharge hopper 8. When blocking the material, the telescopic end of the hydraulic cylinder 91 moves downward. The telescopic end of the hydraulic cylinder 91 pushes the first connecting plate 92 downward. The first connecting plate 92 drives the connecting shaft 93 to rotate. The connecting shaft 93 drives the baffle 95 to rotate downward through the second connecting plate 94. After the baffle 95 rotates downward, the discharge hopper 8 is sealed, and the discharge hopper 8 is quickly sealed.

[0028] Embodiment 4: When the first pressing mechanism 5, the second pressing mechanism 6 and the third pressing mechanism 7 press and laminate the material, for the material extrusion and conveying mechanism 10, the belt on the conveying mechanism 10 is sunken downward after being pressed, thereby reducing the pressing effect on the material. Refer to Figure 2 , as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that the conveying mechanism 10 includes a frame 101. The frame 101 is fixedly connected to the bottom end of the bracket 3. A belt 102 is sleeved on the frame 101. A plurality of support rollers 103 are rotatably connected to the frame 101 at equal intervals along the length direction. An elastic sleeve 104 is sleeved on each support roller 103. Each elastic sleeve 104 is in contact with the lower surface of the upper end of the belt 102. The elastic sleeve 104 is an elastic rubber sleeve. The support roller 103 supports the upper belt 102 through the elastic sleeve 104. When the material extrudes the elastic sleeve 104, the elastic sleeve 104 supports the belt 102, so that the belt 102 will not be sunken downward after being extruded by the material, thereby improving the extrusion effect on the material.

[0029] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
