Description

Technical Field

[0001] The utility model relates to the technical field of floor scales, and more specifically relates to a weighing floor scale on which garbage bins can be placed in multiple directions. Background Art

[0002] Real-time quality monitoring of garbage in outdoor trash cans can help relevant departments understand the overflowing situation of the trash cans, so as to facilitate timely garbage cleaning, keep the environment clean, and reduce the possibility of garbage being scattered into the surrounding environment. Through real-time data feedback on the garbage filling situation of each trash can, reasonable garbage collection and treatment plans can be made to avoid waste of resources and time delays. At the same time, the proportion of different types of garbage in each trash can can be understood in a timely manner to better guide garbage sorting work and improve the recycling rate of garbage resources.

[0003] At present, the garbage quality monitoring of outdoor mobile garbage bins is completed by a special garbage bin weighing scale. Our company applied for a utility model patent with announcement number CN219511665U on April 13, 2023 and authorized on August 11, 2023, disclosing a garbage bin weighing scale for a garbage room, which includes a support plate seat 1, a weighing sensor 2, a weighing plate 3, a back frame and a hoop arm. The weighing plate has a connecting seat, which is a convex structure from the upper end surface of the weighing plate to the upper direction. A storage groove is provided on the lower end surface of the plate, and the weighing sensor is arranged in the storage groove. When the weighing sensor is embedded in the storage groove, under the support of the weighing sensor, the connecting seat and the weighing plate integrated therewith are weighed upward away from the support plate seat. Therefore, the weighing plate is suspended above the support plate seat. The interval between the support plate seat and the weighing plate is a space for the elastic body of the weighing sensor to undergo elastic deformation. Two groups of clamp arms are arranged, and the two clamp arms are rotatably connected to the two ends of the back frame through the first pin shaft, and extend to the top of the weighing plate.

[0004] During actual use of the trash can weighing scale with the above structure, it was found that due to the design of the connecting seat on the weighing plate, the width of the space between the two connecting seats was limited, so that the trash can could only be moved to the weighing plate in a fixed reverse direction and could not maintain an arbitrary placement direction. Therefore, there is a problem that the garbage can cleaning time is easily delayed and the garbage transfer efficiency is affected. Utility Model Content

[0005] In view of the above situation, in order to overcome the problem that the garbage bin weighing scale in the above-mentioned prior art can only be moved to the weighing plate in a fixed reverse direction due to the design of the connecting seat on the weighing plate, thereby delaying the time for cleaning the garbage bin and affecting the efficiency of garbage transportation, the purpose of the utility model is to provide a garbage bin weighing scale that can move the garbage bin to the weighing plate at any angle, and there is no need to pre-place the garbage bin in a fixed orientation when moving it to the weighing plate, so that the time for cleaning the garbage bin can be significantly reduced and the garbage removal efficiency is improved.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0027] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of simplifying the description, and do not indicate or imply that the directions are specific directions that must be possessed and specific directions, structures, and operations, and therefore should not be understood as limitations on the present utility model.

[0029] like Figure 1 as well as Figures 5 to 7As shown, the utility model relates to a weighing scale on which garbage bins can be placed in multiple directions, the weighing scale comprising a support plate seat 1, a weighing plate 2 and a weighing sensor 3, wherein the weighing plate 2 is in the shape of a flat plate, and an upper receiving groove 201 is only provided on one end surface, the weighing plate 2 is covered on the support plate seat 1 through the upper receiving groove 201, so that the support plate seat 1 is built-in, and the side of the weighing plate 2 facing away from the support plate seat 1 is used for placing the garbage bin, and a lower receiving groove 101 is provided on the support plate seat 1, specifically, the lower receiving groove 101 is located on the end surface of the support plate seat 1 opposite to the weighing plate 2, the weighing sensor 3 is buried in the lower receiving groove 101, and the shape of the lower receiving groove 101 matches the shape of the weighing sensor 3, thereby ensuring the stability of the installation of the weighing sensor 3, preventing it from shifting or deflecting, and improving the accuracy of the garbage weighing result. The signal input end of the weighing sensor 3 is connected to the weighing plate 2 located above. When the trash can is placed on the weighing surface of the weighing plate 2, the weighing sensor 3 can sense each change in the mass of the trash in the trash can under the action of pressure, and provide timely feedback so as to accurately understand the overflow situation of the trash can. The utility model replaces the weighing plate 2 formed with a convex platform-shaped connecting seat with a weighing plate 2 that is an overall flat plate. Without the restriction of the connecting seat, the area of ​​the weighing surface of the weighing plate 2 used to support the trash can is expanded, so that the trash can can be moved to the weighing plate 2 in an inverted state and can also be supported by the weighing plate 2 in any placement state such as upright. There is no need to adjust the placement state when the trash can is moved to the weighing plate 2, thereby saving the time spent on cleaning the trash can and significantly improving the efficiency of garbage transportation.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, it also includes a back frame 4 and a hoop arm 5. One side of the support plate seat 1 extends to the outside of the upper storage groove 201 of the weighing plate 2 and is exposed to the external space. The back frame 4 is arranged on the part of the support plate seat 1 located in the external space. From the overall point of view, the back frame 4 stands on one side of the weighing plate 2 and is opposite to the weighing plate 2, so that it can limit the movement from the rear of the trash can placed on the weighing plate 2 to prevent the trash can from moving too far backward and slipping. The hoop arm 5 is configured with two groups. The two hoop arms 5 are rotatably connected to the two ends of the back frame 45 through the inner rotating pin 6 and extend to the top of the weighing plate 2. A placement space opposite to the upper and lower sides of the weighing plate 2 is formed between the two hoop arms 5. The trash can placed on the weighing plate 2 is supported by the weighing plate 2 below. The support is located in the placement space between the two hoop arms 5. The hoop arms 5 are tightly clamped on the trash can, so that the left and right sides of the trash can are blocked by the hoop arms 5, thereby limiting the direction in which the trash can moves into the weighing plate 2, that is, the trash can can only move from the front side of the weighing plate 2 to the weighing plate 2, and the trash can is firmly held on the weighing plate 2, effectively limiting the free movement of the trash can. In addition, the two hoop arms 5 can rotate toward and away from each other through their respective inner rotating pins 6. When rotating away from each other, the diameter of the placement space is expanded, and when rotating toward each other, the diameter of the placement space is restored. When the diameter of the placement space is expanded to exceed the width of the trash can, the trash can can be smoothly moved to the weighing plate 2 or removed from the weighing plate 2.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, a ramp platform 202 is formed on the weighing plate 2, which is opposite to the opening on the side of the two clamping arms 5 away from the back frame 4. One side of the ramp platform 202 is connected to the ground, so that the trash can can be moved along the ramp platform 202 to the weighing plate 2, thereby significantly improving the effort-saving feeling of moving the trash can and solving the problem that the step between the weighing plate 2 and the ground affects the difficulty of moving the trash can.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, a torsion spring 7 is mounted on the inner rotating pin 6, and both ends of the torsion spring 7 are respectively connected to the hoop arm 5 and the back frame 4. The torsion spring 7 is stretched or deformed back in a stretched state when the connected hoop arm 5 rotates toward or away from the other hoop arm 5. When a trash can is placed on the weighing plate 2, the two hoop arms 5 will be supported by the outer wall of the trash can and extend outward, thereby stretching the torsion spring 7. The elastic force generated by the stretching of the torsion spring 7 enables the hoop arm 5 to hold the trash can tightly, thereby realizing the stable placement of the trash can. When the trash can is removed from the weighing plate 2, the two hoop arms 5 can automatically rotate under the action of the torsion spring 7, and no manual control is required, thereby reducing the workload when cleaning the trash can.

[0033] like Figure 1 , Figure 3 , Figure 5As shown, it also includes a guide wheel 8, each clamp arm 5 has at least one guide wheel 8 corresponding to it, the guide wheel 8 is hinged to the corresponding clamp arm 5 through an external rotating pin 9, and the guide wheels 8 on the two clamp arms 5 remain relative, and the guide wheel 8 can be tightly attached to the outer wall of the trash can on the weighing plate 2 under the pressure of the torsion spring 7. The guide wheel 8 with a circular shape continuously rolls along the outer wall of the trash can when the trash can is moved onto the weighing plate 2 or moved out from the weighing plate 2, so that the friction between the trash can and the guide wheel 8 is converted into rolling friction, thereby increasing the speed of moving the trash can and further reducing the workload of the operator.

[0034] like Figure 1 and Figure 5 As shown, there are at least two weighing sensors 3, each of which is arranged on both sides of the central plane in the longitudinal direction of the support plate seat 1. The symmetrical arrangement of the weighing sensors 3 can ensure that the load applied to the weighing sensors 3 by the trash can is evenly distributed to obtain a more accurate weighing result. For example, when the trash can is slightly shaken or subjected to a slight lateral force, the weighing error can be effectively reduced. At the same time, the risk of wear and damage of the weighing sensors 3 is reduced, and the service life is extended.

[0035] like Figure 5 As shown, the support plate seat 1 has a concave shape, and the weighing sensors 3 are arranged at both ends of the support plate seat 1. Based on the above arrangement, the materials required for manufacturing the support plate seat 1 with a concave shape can be greatly saved, thereby reducing the manufacturing cost of the weighing scale of the utility model.

[0036] like Figure 1 and Figure 5 As shown, there are four weighing sensors 3, and each weighing sensor 3 is symmetrically arranged in pairs at the two ends of the support plate seat 1 and at positions opposite to the front and rear sides of the weighing plate 2. Based on the above arrangement, by increasing the number of weighing sensors 3 and evenly distributing the weighing sensors 3, it is ensured that the weighing result is more accurate.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, the support plate seat 1 is detachably fixed to the weighing plate 2 by means of threaded fasteners 10. It should be mentioned that there are multiple threaded fasteners 10, thereby utilizing multi-point fixation to enhance the stability of the fixation between the support plate seat 1 and the weighing plate 2, and the threaded connection method can realize the installation of the support plate seat 1 and the weighing plate 2 only by a rotating action, thereby realizing quick disassembly and assembly.

[0038] Combination Figures 1 to 7When the trash can weighing scale of the utility model moves from the ground in front of the scale to the weighing plate 2, the guide wheels 8 of the two hoop arms 5 of the back frame 4 first contact the outer wall of the trash can. As the trash can moves, the guide wheels 8 together with the connected hoop arms 5 are extended outward, so that the distance between the two hoop arms 5 is expanded until the distance is as wide as the trash can, so that the trash can can be smoothly moved to the weighing plate 2 and supported by the weighing plate 2. The weighing plate 2, which is a flat plate as a whole, can support the trash can in any placement state, and there is no need to adjust the placement state when the trash can is moved to the weighing plate 2. When the trash can is placed, the two hoop arms 5 drive the connected guide wheels 8 to rotate back to each other under the elastic force of the torsion spring 7, and tightly hold the outer wall of the trash can, so that the garbage is stably confined on the weighing plate 2 and in the space between the two hoop arms 5 and the back frame 4.

[0039] The above embodiments and descriptions are only for explaining the principle and the best embodiment of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
