DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1: Reference Figure 1-4 A volumetric scale for weighing bagged loose materials, comprising a bracket 3, both sides of which are fixedly connected with a plurality of legs 4, the upper end of the bracket 3 is fixedly connected with a lower bin 1, the lower bin 1 is connected with a level meter 2 for detecting the material height, the bottom end of the bracket 3 is fixedly connected with a conveying mechanism 10, the lower bin 1 is sequentially connected with a first pressing mechanism 5, a second pressing mechanism 6 and a third pressing mechanism 7 along its length, the first pressing mechanism 5, the second pressing mechanism 6 and the third pressing mechanism 7 have the same structure, 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 successively, the bottom end of the bracket 3 is connected with a discharge hopper 8, the bracket 3 is connected with an opening and closing mechanism 9 for controlling the material to enter the discharge hopper 8.

[0023] Working process:

[0024] The material is poured into the lower silo 1, and the level meter 2 detects the material height in the lower silo 1 to prevent the material from falling from the upper side of the lower silo 1. The material in the lower silo 1 falls on the conveying mechanism 10, and the bracket 3 limits the two sides of the conveying mechanism 10 to prevent the material from falling from the side of the conveying mechanism 10;

[0025] At the same time, 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 squeeze the material on the upper end of the conveying mechanism 10 in turn. The conveying mechanism 10 conveys the material and supports the material at the same time. The material is squeezed by the first pressing mechanism 5, the second pressing mechanism 6 and the third pressing mechanism 7 in turn during the conveying process to reduce the gap between the materials. After the material is pressed, the opening and closing mechanism 9 is opened. After the opening and closing mechanism 9 is opened, the material enters the discharge hopper 8. Under the transportation of the conveying mechanism 10, no material accumulation occurs. The material is released from the discharge hopper 8. After being pressed by the third pressing mechanism 7, the material thickness is constant, and the conveying speed of the conveying mechanism 10 is constant. The volume of the material discharged from the discharge hopper 8 is obtained according to the material conveying speed and the material thickness, which is convenient for weighing the material.

[0026] Embodiment 2: When the first pressing mechanism 5, the second pressing mechanism 6 and the third pressing mechanism 7 are pressing and pressing the material, part of the material is easily wound around the second pressing mechanism 6. When the material is wound around the second pressing mechanism 6 too much, the pressing effect of the material is affected. Figure 2-3 As another preferred embodiment of the present invention, the difference from the embodiment 1 is that the second pressing mechanism 6 includes a reducer 61, the reducer 61 is fixedly connected to the bracket 3, the reducer 61 is connected to a driving motor 62, the output end of the reducer 61 is fixedly connected to 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 plurality of rollers 65 are connected between the two fixed plates 64 at equal intervals along the axis direction, the rollers 65 are located in the bracket 3, and a gap is provided between two adjacent rollers 65. After the driving motor 62 is started, the reducer 61 is driven to work, the reducer 61 drives the rotating shaft 63 to rotate, the rotating shaft 63 drives the fixed plate 64 to rotate, and the fixed plate 64 drives the roller 65 to rotate. After the roller 65 rotates, the conveyed material is rolled to reduce the gap between the materials, and part of the material is wrapped around the roller 65. During the rotation of the roller 65, the material on the roller 65 falls off from the gap, thereby reducing the winding of the material on the roller 65 and maintaining the compaction effect on the material.

[0027] Example 3: When preventing the material from entering the discharge hopper 8, the material cannot be quickly blocked, refer to Figure 2-3As another preferred embodiment of the present invention, 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 to two parallel second connecting plates 94, one end of the two parallel second connecting plates 94 are fixedly connected to 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 to the 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 hydraulic cylinder 91 is rotatably connected to the first connecting plate 92, and the first connecting plate 92 is fixedly connected to the connecting shaft 93. The telescopic end of the cylinder 91 moves upward, and the telescopic end of the hydraulic cylinder 91 pulls the first connecting plate 92, and the first connecting plate 92 drives the connecting shaft 93 to rotate, and 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, and the telescopic end of the hydraulic cylinder 91 pushes the first connecting plate 92 downward, and the first connecting plate 92 drives the connecting shaft 93 to rotate, and 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 press the material, the material presses the conveying mechanism 10, and the belt on the conveying mechanism 10 is pressed and depressed downward, thereby reducing the pressing effect on the material. Figure 2 As another preferred embodiment of the present invention, 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, and a plurality of support rollers 103 are rotatably connected to the frame 101 at equal intervals along the length direction, each support roller 103 is sleeved with an elastic sleeve 104, 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, and the support roller 103 supports the upper end of the belt 102 through the elastic sleeve 104. When the material squeezes the elastic sleeve 104, the elastic sleeve 104 supports the belt 102, so that the belt 102 will not sag downward after being squeezed by the material, thereby improving the squeezing effect on the material.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
