Abstract
Description
Technical Field
[0001] This application belongs to the field of engineering machinery technology, specifically relating to a weighing scale and a mixing plant. Background Technology
[0002] Mobile mixing plants can be towed and moved as a whole. A traction point is set at the front of the main frame. Therefore, mobile plants usually adopt a single-leg structure with the main load-bearing platform cantilevered, that is, the mixing host and the upper weighing scale are both located on the cantilevered platform.
[0003] Because additive scales have a small volume, they typically use a single-point suspension structure, hanging on an additive scale frame. However, during production, the platform may wobble. Due to the single-point suspension structure, the scale body wobbles significantly, causing fluctuations in the scale readings and resulting in large weighing errors, failing to meet the accuracy requirements for additive weighing. Utility Model Content
[0004] The purpose of this application is to provide a weighing scale and a mixing plant to solve the problem that the existing weighing scale adopts a single-point suspension structure, which causes fluctuations in the reading of the admixture scale due to shaking, resulting in large weighing errors and affecting the weighing accuracy.
[0005] To achieve the above objectives, the first aspect of this application provides a weighing scale, comprising:
[0006] Scale frame;
[0007] The scale body is suspended from the top of the scale frame;
[0008] The limiting component is fixedly installed on the outer peripheral surface of the scale body;
[0009] The connecting component has at least two hinged parts at both ends along its length direction, wherein at least two of the hinged parts at one end are hinged to the side wall of the weighing frame, and at least two of the hinged parts at the other end are hinged to the limiting component.
[0010] As a further improvement to the above technical solution:
[0011] In some embodiments, the limiting component includes a limiting body, which is fixedly installed on the outer peripheral surface of the scale body, and the limiting body is provided with a first ear seat corresponding to the hinge portion at one end of the connecting component.
[0012] In some embodiments, the limiting body is a closed frame, and a closed opening adapted to the outer periphery shape of the scale body is formed inside the closed frame;
[0013] Alternatively, the limiting body may be an open frame, with an opening inside the open frame that is adapted to the shape of the outer periphery of the scale body.
[0014] In some embodiments, the limiting body is an open frame member, and ear plates are respectively provided on both sides of the opening of the open frame member;
[0015] The limiting component further includes a first fastener, which connects the ear plates on both sides of the opening of the opening frame to the ear plates.
[0016] In some embodiments, the limiting component further includes a first fastener;
[0017] The limiting body includes a first splicing component and a second splicing component that are spliced together to form a through opening. Both ends of the first splicing component and the second splicing component are provided with ear plates. When the limiting body is spliced, the two ear plates located at the same end are connected by the first fastener.
[0018] In some embodiments, the connection assembly includes a connection bracket and at least two connection rods;
[0019] All the connecting rods are arranged at intervals and located in the horizontal plane, wherein each connecting rod has a hinge at both ends;
[0020] The connecting bracket is fixedly connected to at least two of the connecting rods.
[0021] In some embodiments, the connecting rod includes a connecting rod body, and both ends of the connecting rod body are provided with hinge joints for hinged connection.
[0022] In some embodiments, the hinge joint is a spherical bearing hinge joint.
[0023] In some embodiments, the hinge joint is threadedly connected to the connecting rod body;
[0024] The connecting bracket includes a second fastener, a first bracket member, and a second bracket member. The first bracket member is fixedly installed on the hinge joint at one end of the connecting rod body, and the second bracket member is fixedly installed on the hinge joint at the other end of the connecting rod body.
[0025] The first support member and the second support member are arranged in alignment and stacked vertically in the middle of the connecting rod body. Both the first support member and the second support member are provided with waist-shaped holes in the stacked area. The second fastener passes through the waist-shaped holes to connect the first support member and the second support member.
[0026] A second aspect of this application also provides a mixing plant, including a weighing scale according to the first aspect described above.
[0027] Compared with existing technologies, the weighing scale and mixing plant provided in this application have at least the following technical advantages:
[0028] The weighing scale provided in this application uses a limiting component fixedly installed on the outer circumference of the scale body. The side walls of the scale frame and the limiting component are then hinged together at both ends of a connecting component. This hinged connection ensures that the limiting component and the scale body have vertical freedom, meaning that the weighing of the scale body in the vertical direction is not restricted, ensuring weighing accuracy. Furthermore, since at least two hinges are provided at both ends of the connecting component, the hinged connection restricts the swing of the limiting component and the scale body in the horizontal plane, preventing swaying of the scale body. Thus, the weighing scale provided in this application effectively solves the problem of swaying in the horizontal plane, avoiding weighing errors caused by swaying and improving weighing accuracy. When applied to a mixing plant, it can improve the weighing accuracy of admixtures, thereby improving the production quality of concrete.

[0051] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0052] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.
[0053] Example 1
[0054] Please see Figure 1 and Figure 2 This embodiment provides a weighing scale to prevent the scale body 400 from swaying in the horizontal plane.
[0055] The weighing scale provided in this embodiment includes a weighing frame 100, a connecting assembly 200, a limiting assembly 300, and a weighing body 400. The weighing frame 100 has a top 110 and side walls 120. The top 110 of the weighing frame 100 is provided with a suspension part 130. The weighing body 400 is suspended on the suspension part 130 by a weighing sensor 410.
[0056] The limiting component 300 is fixedly installed on the outer peripheral surface of the scale body 400. The fixed connection method can be detachable or non-detachable. Detachable connection methods include screw connection, snap-fit or clamping interference assembly; non-detachable connection methods include integral molding or welding connection.
[0057] The connecting component 200 is disposed on the side wall 120 of the weighing frame 100. Specifically, the connecting component 200 has at least two hinged portions at both ends along its own length direction, wherein at least two hinged portions at one end are hinged to the side wall of the weighing frame 100, and at least two hinged portions at the other end are hinged to the limiting component 300.
[0058] In this embodiment, a scheme in which two hinge portions are provided at both ends of the connecting component 200 is illustrated. It should be understood that the number of hinge portions can also be three, four, or others. This embodiment is merely illustrative and is not intended to limit the scope of protection of this application.
[0059] Thus, the weighing scale provided in this embodiment is connected to the limiting component 300 via the connecting component 200, and the limiting component 300 is fixedly installed on the outer peripheral surface of the scale body 400. The hinged connection ensures that the limiting component 300 and the scale body 400 have vertical freedom, meaning that the weighing of the scale body 400 is not restricted in the vertical direction, ensuring weighing accuracy. Furthermore, since the connecting component 200 has at least two hinged parts at both ends, the connecting component 200 restricts the swing of the limiting component 300 and the scale body 400 in the horizontal plane after the hinged connection, preventing the scale body 400 from swaying in the horizontal plane and ensuring normal weighing operation.
[0060] Compared with existing technologies, the weighing scale provided in this embodiment can effectively solve the problem of the scale body 400 swaying on the horizontal plane, avoid weighing errors caused by swaying, and improve weighing accuracy.
[0061] Example 2
[0062] Please see Figure 1 and Figure 2 This embodiment provides a weighing scale to prevent the scale body 400 from swaying in the horizontal plane. This embodiment is an improvement on the technology of Embodiment 1 described above. The difference between Embodiment 1 and Embodiment 1 is as follows:
[0063] In this embodiment, the limiting component 300 and the scale body 400 are fitted together by an interference fit.
[0064] Specifically, the limiting component 300 includes a limiting body 320 and a first ear seat 310, with a through-hole 321 formed in the middle of the limiting body 320. The first ear seat 310 is disposed on the limiting body 320 and is hingedly connected to the corresponding hinge portion on the connecting component 200. The shape of the through-hole 321 is adapted to the shape of the outer peripheral surface of the scale body 400; that is, when the outer peripheral surface of the scale body 400 is cylindrical or prismatic, the corresponding through-hole 321 is circular or polygonal.
[0065] When the limiting component 300 is installed, the scale body 400 is arranged through the through-hole 321, and the limiting body 320 is fitted on the outer peripheral surface of the scale body 400 and is interference-fitted with the scale body 400.
[0066] In some embodiments, the limiting body 320 is a closed frame 320a, and the closed frame 320a forms a closed opening 321 that is adapted to the outer periphery shape of the scale body 400.
[0067] In other embodiments, the limiting body 320 is an open frame 320b, and the open frame 320b forms an opening 321 that is adapted to the outer peripheral shape of the scale body 400.
[0068] Furthermore, the number of first ear seats 310 on the limiting body 320 corresponds to the number of hinge parts on the upper end of the connecting assembly 200, that is, two are provided for each.
[0069] Please refer to the following: Figure 3 and Figure 4 Furthermore, in this embodiment, the limiting body 320 is a closed frame 320a, and two first ear seats 310 are disposed on the outer peripheral wall of the closed frame 320a. The opening 321 is formed in the middle of the closed frame 320a. When the outer peripheral shape of the scale body 400 is cylindrical, the shape of the opening 321 is circular. The corresponding closed frame 320a can be designed as an annulus.
[0070] When installing the scale body 400, first suspend the scale body 400 on the suspension part 130, then slip the limiting body 320 over the scale body 400 from the bottom, ensuring there is no play, and finally connect the first ear seat 310 to the connecting component 200. Alternatively, the limiting body 320 can be slipped over the scale body 400 first, then the scale body 400 is suspended and the connecting component 200 is installed.
[0071] Please see Figure 2 and Figure 4Furthermore, the connecting assembly 200 includes a connecting bracket 220 and at least two connecting rods 210, which are spaced apart and located in a horizontal plane. In this embodiment, the number of connecting rods 210 corresponds one-to-one with the number of first ear seats 310, that is, in this embodiment, the number of connecting rods 210 is also two. The connecting bracket 220 is fixedly connected to the two connecting rods 210.
[0072] The connecting rod 210 has hinged parts at both ends. One hinged part is hinged to the second ear seat 140 on the scale frame 100, and the other hinged part is hinged to the first ear seat 310 of the limiting component 300.
[0073] Please refer to the following: Figure 5 Specifically, the connecting rod 210 includes a connecting rod body 211, and both ends of the connecting rod body 211 are provided with hinge joints 212 at the hinged portion. Among them, the hinge joint 212 located at one end of the connecting rod body 211 is hingedly connected to the second ear seat 140 on the corresponding weighing frame 100, and the hinge joint 212 located at the other end of the connecting rod body 211 is hingedly connected to the first ear seat 310 on the limiting component 300.
[0074] Optionally, the hinge joint 212 can be a spherical plain bearing hinge. Both the first lug 310 and the second lug 140 have two opposing lugs, forming a space between them to accommodate the spherical plain bearing hinge. The spherical plain bearing hinge is positioned between the two lugs and hinged together by a pin. Alternatively, a conventional hinge can be used, with its hinge axis parallel to the horizontal plane. It is understood that spherical plain bearings have lower requirements for manufacturing and installation compared to conventional hinges.
[0075] In some embodiments, at least one hinge joint 212 engages with the threaded joint of the connecting rod body 211. Thus, the verticality of the scale body 400 can be adjusted by turning the connecting rod body 211 or the hinge joint 212 to adjust the length of the entire connecting rod 210.
[0076] like Figure 5 As shown, in this embodiment, both ends of the connecting rod 211 and the corresponding hinge joints 212 are threaded. This further increases the adjustment range of the length of the connecting rod 210 and improves the convenience of adjustment.
[0077] Please see Figure 4 , Figure 6 and Figure 7 Furthermore, the connecting bracket 220 connects two connecting rods 210 to improve the structural stability of the connecting assembly 200 and limit its swing in the horizontal plane.
[0078] Specifically, the connecting bracket 220 includes a second fastener 221, a first bracket member 222, and a second bracket member 223. The first bracket member 222 is fixedly installed on the hinge joint 212 at one end of the connecting rod 211; the second bracket member 223 is fixedly installed on the hinge joint 212 at the other end of the connecting rod 211. The first bracket member 222 and the second bracket member 223 are aligned and stacked vertically in the middle of the connecting rod 211.
[0079] The first support member 222 and the second support member 223 are each provided with at least one waist-shaped hole 220a in the stacking area. The second fastener 221 passes through the waist-shaped hole 220a on the first support member 222 and the second support member 223 to connect the first support member 222 and the second support member 223.
[0080] In this embodiment, the length direction of the oblong hole 220a is consistent with the length direction of the connecting rod 211. Thus, to accommodate the length adjustment of the connecting rod 210, the distance between the first support member 222 and the second support member 223 is adjusted along the length direction of the oblong hole 220a, and then fixed by the second fastener 221.
[0081] Optionally, such as Figure 6 As shown, the first support member 222 and the second support member 223 are L-shaped structures.
[0082] Optionally, the second fastener 221 is a bolt.
[0083] Example 3
[0084] Please see Figure 1 and Figure 2 This embodiment provides a weighing scale to prevent the scale body 400 from swaying in the horizontal plane. This embodiment is an improvement on the technology of Embodiment 1 described above. The difference between Embodiment 1 and Embodiment 1 is as follows:
[0085] In this embodiment, the limiting component 300 and the scale body 400 are fitted together by an interference fit.
[0086] Specifically, the limiting component 300 includes a limiting body 320 and a first ear seat 310, with a through-hole 321 formed in the middle of the limiting body 320. The first ear seat 310 is disposed on the limiting body 320 and is hingedly connected to the corresponding hinge portion on the connecting component 200. The shape of the through-hole 321 is adapted to the shape of the outer peripheral surface of the scale body 400; that is, when the outer peripheral surface of the scale body 400 is cylindrical or prismatic, the corresponding through-hole 321 is circular or polygonal.
[0087] When the limiting component 300 is installed, the scale body 400 is arranged through the through-hole 321, and the limiting body 320 is fitted on the outer peripheral surface of the scale body 400 and is interference-fitted with the scale body 400.
[0088] Please refer to the following: Figure 8 and Figure 9 In this embodiment, the limiting component 300 further includes a first fastener 330. The limiting body 320 is an open frame 320b, and ear plates 322 are respectively provided on both sides of the opening of the open frame 320b. The ear plates 322 are connected by the first fastener 330. The two first ear seats 310 are symmetrically designed with respect to the opening of the open frame 320b.
[0089] Optionally, the first fastener 330 is a bolt or a rivet.
[0090] When installing the weighing body 400, there are two methods: First, suspend the weighing body 400 on the suspension part 130, then insert the limiting body 320 from the bottom of the weighing body 400, or open the opening of the limiting body 320 and insert it radially into the weighing body 400. Then, install the first fastener 330 to lock it in place, so that the limiting body 320 hugs the weighing body 400. Finally, connect the first ear seat 310 to the connecting assembly 200. Second, pre-install the limiting body 320 on the weighing body 400, then suspend the weighing body 400 on the suspension part 130. Adjust the position of the limiting body 320 vertically, then install the first fastener 330 to lock it in place. Finally, connect the first ear seat 310 to the connecting assembly 200.
[0091] Please see Figure 2 and Figure 4 Furthermore, the connecting assembly 200 includes a connecting bracket 220 and at least two connecting rods 210, which are spaced apart and located in a horizontal plane. In this embodiment, the number of connecting rods 210 corresponds one-to-one with the number of first ear seats 310, that is, in this embodiment, the number of connecting rods 210 is also two. The connecting bracket 220 is fixedly connected to the two connecting rods 210.
[0092] The connecting rod 210 has hinged parts at both ends. One hinged part is hinged to the second ear seat 140 on the scale frame 100, and the other hinged part is hinged to the first ear seat 310 of the limiting component 300.
[0093] Please refer to the following: Figure 5 Specifically, the connecting rod 210 includes a connecting rod body 211, and both ends of the connecting rod body 211 are provided with hinge joints 212 at the hinged portion. Among them, the hinge joint 212 located at one end of the connecting rod body 211 is hingedly connected to the second ear seat 140 on the corresponding weighing frame 100, and the hinge joint 212 located at the other end of the connecting rod body 211 is hingedly connected to the first ear seat 310 on the limiting component 300.
[0094] Optionally, the hinge joint 212 can be a spherical plain bearing hinge. Both the first lug 310 and the second lug 140 have two opposing lugs, forming a space between them to accommodate the spherical plain bearing hinge. The spherical plain bearing hinge is positioned between the two lugs and hinged together by a pin. Alternatively, a conventional hinge can be used, with its hinge axis parallel to the horizontal plane. It is understood that spherical plain bearings have lower requirements for manufacturing and installation compared to conventional hinges.
[0095] In some embodiments, at least one hinge joint 212 engages with the threaded joint of the connecting rod body 211. Thus, the verticality of the scale body 400 can be adjusted by turning the connecting rod body 211 or the hinge joint 212 to adjust the length of the entire connecting rod 210.
[0096] like Figure 5 As shown, in this embodiment, both ends of the connecting rod 211 and the corresponding hinge joints 212 are threaded. This further increases the adjustment range of the length of the connecting rod 210 and improves the convenience of adjustment.
[0097] Please see Figure 4 , Figure 6 and Figure 7 Furthermore, the connecting bracket 220 connects two connecting rods 210 to improve the structural stability of the connecting assembly 200 and limit its swing in the horizontal plane.
[0098] Specifically, the connecting bracket 220 includes a second fastener 221, a first bracket member 222, and a second bracket member 223. The first bracket member 222 is fixedly installed on the hinge joint 212 at one end of the connecting rod 211; the second bracket member 223 is fixedly installed on the hinge joint 212 at the other end of the connecting rod 211. The first bracket member 222 and the second bracket member 223 are aligned and stacked vertically in the middle of the connecting rod 211.
[0099] The first support member 222 and the second support member 223 are each provided with at least one waist-shaped hole 220a in the stacking area. The second fastener 221 passes through the waist-shaped hole 220a on the first support member 222 and the second support member 223 to connect the first support member 222 and the second support member 223.
[0100] In this embodiment, the length direction of the oblong hole 220a is consistent with the length direction of the connecting rod 211. Thus, to accommodate the length adjustment of the connecting rod 210, the distance between the first support member 222 and the second support member 223 is adjusted along the length direction of the oblong hole 220a, and then fixed by the second fastener 221.
[0101] Optionally, such as Figure 6 As shown, the first support member 222 and the second support member 223 are L-shaped structures.
[0102] Optionally, the second fastener 221 is a bolt.
[0103] Example 4
[0104] Please see Figure 1 and Figure 2 This embodiment provides a weighing scale to prevent the scale body 400 from swaying in the horizontal plane. This embodiment is an improvement on the technology of Embodiment 1 described above. The difference between Embodiment 1 and Embodiment 1 is as follows:
[0105] In this embodiment, the limiting component 300 and the scale body 400 are fitted together by an interference fit.
[0106] Specifically, the limiting component 300 includes a limiting body 320 and a first ear seat 310, with a through-hole 321 formed in the middle of the limiting body 320. The first ear seat 310 is disposed on the limiting body 320 and is hingedly connected to the corresponding hinge portion on the connecting component 200. The shape of the through-hole 321 is adapted to the shape of the outer peripheral surface of the scale body 400; that is, when the outer peripheral surface of the scale body 400 is cylindrical or prismatic, the corresponding through-hole 321 is circular or polygonal.
[0107] When the limiting component 300 is installed, the scale body 400 is arranged through the through-hole 321, and the limiting body 320 is fitted on the outer peripheral surface of the scale body 400 and is interference-fitted with the scale body 400.
[0108] Please refer to the following: Figure 10 Specifically, the limiting component 300 also includes a first fastener 330. The limiting body 320 includes a first splicing piece 320c and a second splicing piece 320d that are spliced together to form the through-hole 321. Both ends of the first splicing piece 320c and the second splicing piece 320d are provided with ear plates 322, and the two ear plates 322 located at the same end are connected by the first fastener 330.
[0109] Each of the first splicing component 320c and the second splicing component 320d is provided with a first ear seat 310, and the two first ear seats 310 are symmetrical about the connection between the first splicing component 320c and the second splicing component 320d.
[0110] In some embodiments, two first ear mounts 310 may be disposed on a first splicing member 320c or a second splicing member 320d.
[0111] Optionally, when the opening 321 is circular, the first splice 320c and the second splice 320d can be designed as arc-shaped parts.
[0112] Optionally, the first splicing component 320c and the second splicing component 320d are semi-circular arc components.
[0113] It should also be noted that this embodiment only illustrates one first splicing component 320c and one second splicing component 320d. The number of first splicing components 320c and second splicing components 320d can also be multiple. Furthermore, the dimensions of the first splicing component 320c and the second splicing component 320d can be designed to be the same or different.
[0114] Optionally, the first fastener 330 is a bolt or a rivet.
[0115] When installing the scale body 400, there are two methods: First, assemble the first splicing component 320c and the second splicing component 320d using the first fastener 330. Then, suspend the scale body 400 on the suspension part 130. Next, insert the limiting body 320 through the bottom of the scale body 400 and then connect the first ear seat 310 to the connecting assembly 200. Second, suspend the scale body 400 on the suspension part 130. Connect the pipes below the scale body 400. Then, install the first splicing component 320c and the second splicing component 320d along the radial direction of the scale body 400, so that the ends of the first splicing component 320c and the second splicing component 320d are opposite each other. Then, insert the first fastener 330 into the ear plates 322 at both ends of the first splicing component 320c and the second splicing component 320d to fix them. Finally, connect the first ear seat 310 to the connecting assembly 200.
[0116] Please see Figure 2 and Figure 4 Furthermore, the connecting assembly 200 includes a connecting bracket 220 and at least two connecting rods 210, which are spaced apart and located in a horizontal plane. In this embodiment, the number of connecting rods 210 corresponds one-to-one with the number of first ear seats 310, that is, in this embodiment, the number of connecting rods 210 is also two. The connecting bracket 220 is fixedly connected to the two connecting rods 210.
[0117] The connecting rod 210 has hinged parts at both ends. One hinged part is hinged to the second ear seat 140 on the scale frame 100, and the other hinged part is hinged to the first ear seat 310 of the limiting component 300.
[0118] Please refer to the following: Figure 5 Specifically, the connecting rod 210 includes a connecting rod body 211, and both ends of the connecting rod body 211 are provided with hinge joints 212 at the hinged portion. Among them, the hinge joint 212 located at one end of the connecting rod body 211 is hingedly connected to the second ear seat 140 on the corresponding weighing frame 100, and the hinge joint 212 located at the other end of the connecting rod body 211 is hingedly connected to the first ear seat 310 on the limiting component 300.
[0119] Optionally, the hinge joint 212 can be a spherical plain bearing hinge. Both the first lug 310 and the second lug 140 have two opposing lugs, forming a space between them to accommodate the spherical plain bearing hinge. The spherical plain bearing hinge is positioned between the two lugs and hinged together by a pin. Alternatively, a conventional hinge can be used, with its hinge axis parallel to the horizontal plane. It is understood that spherical plain bearings have lower requirements for manufacturing and installation compared to conventional hinges.
[0120] In some embodiments, at least one hinge joint 212 engages with the threaded joint of the connecting rod body 211. Thus, the verticality of the scale body 400 can be adjusted by turning the connecting rod body 211 or the hinge joint 212 to adjust the length of the entire connecting rod 210.
[0121] like Figure 5 As shown, in this embodiment, both ends of the connecting rod 211 and the corresponding hinge joints 212 are threaded. This further increases the adjustment range of the length of the connecting rod 210 and improves the convenience of adjustment.
[0122] Please see Figure 4 , Figure 6 and Figure 7 Furthermore, the connecting bracket 220 connects two connecting rods 210 to improve the structural stability of the connecting assembly 200 and limit its swing in the horizontal plane.
[0123] Specifically, the connecting bracket 220 includes a second fastener 221, a first bracket member 222, and a second bracket member 223. The first bracket member 222 is fixedly installed on the hinge joint 212 at one end of the connecting rod 211; the second bracket member 223 is fixedly installed on the hinge joint 212 at the other end of the connecting rod 211. The first bracket member 222 and the second bracket member 223 are aligned and stacked vertically in the middle of the connecting rod 211.
[0124] The first support member 222 and the second support member 223 are each provided with at least one waist-shaped hole 220a in the stacking area. The second fastener 221 passes through the waist-shaped hole 220a on the first support member 222 and the second support member 223 to connect the first support member 222 and the second support member 223.
[0125] In this embodiment, the length direction of the oblong hole 220a is consistent with the length direction of the connecting rod 211. Thus, to accommodate the length adjustment of the connecting rod 210, the distance between the first support member 222 and the second support member 223 is adjusted along the length direction of the oblong hole 220a, and then fixed by the second fastener 221.
[0126] Optionally, such as Figure 6 As shown, the first support member 222 and the second support member 223 are L-shaped structures.
[0127] Optionally, the second fastener 221 is a bolt.
