Detailed Implementation
[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0030] like Figures 1-4 As shown, a high-precision electronic belt scale according to one embodiment of the present invention includes a belt scale body 1 and a material conveying component 2.
[0031] like Figures 1-4 As shown, the belt scale body 1 includes a conveyor belt 11, and a pair of mounting plates 13 are installed on the front and rear sides of the conveyor belt 11. The conveyor belt 11 is rotatably connected between the pair of mounting plates 13. By rotating the conveyor belt 11, the material can be conveyed and the conveyed material can be measured at the same time.
[0032] like Figures 1-4As shown, the front and rear side wall edges of the conveying belt 11 are integrally formed with material blocking plates 12, which shield the material conveyed on the conveying belt 11. The left and right ends of the conveying belt 11 are each provided with a drive roller 14, which enables the conveying belt 11 to rotate after installation.
[0033] As shown, Figures 1-4 The front end of the drive roller 14 provided at the right end of the conveying belt 11 is provided with a motor 15, which drives the conveying belt 11 to rotate. A plurality of driven rollers 16 are installed in the conveying belt 11, which support the rotation of the conveying belt 11 and ensure stability during rotation.
[0034] As shown, Figures 1-4 The material conveying assembly 2 includes a material conveying bin 21, which is installed on the side of the conveying belt 11 where material is fed, so as to provide the material to be conveyed to the conveying belt 11 through the material conveying bin 21. The material conveying bin 21 is fixedly connected with a sieve plate 22, which is uniformly provided with a plurality of sieve holes 23, so that the material entering the material conveying bin 21 needs to be sieved through the sieve holes 23 on the sieve plate 22, and the sieved material flows through the guide of the sieve holes 23. The bottom of the sieve plate 22 is fixedly connected with a plurality of material guide plates 24 in a transverse manner, which are sequentially arranged between adjacent sieve holes 23, so that the sieved material through the sieve holes 23 flows through the guide of the material guide plates 24, so that the material flows uniformly through the guide of the material guide plates 24 and then uniformly flows out of the lower end of the material conveying bin 21, thereby uniformly distributing the output material in the material conveying bin 21 on the conveying belt 11. The side walls of the plurality of material guide plates 24 are each fixedly connected with a plurality of magnetic attraction plates 25, which can adsorb metal impurities in the material when the material flows through the guide of the material guide plates 24, thereby treating the metal impurities in the material.
[0035] As shown, Figures 1-4 The material conveying bin 21 is provided as a hollow structure in the shape of an inverted trapezoid, and the wall plates on the front and rear sides of the material conveying bin 21 are inclined.
[0036] As shown, Figure 4 As shown, Figure 5 The plurality of material guide plates 24 are arranged in an inclined manner, and the material guide plates 24 are inclined from the center of the material conveying bin 21 to the outer sides of the front and rear sides, so that the sieved material through the sieve holes 23 can be dispersed to the front and rear sides after being guided by the material guide plates 24, so as to uniformly distribute the material guided by the material guide plates 24 on the conveying belt 11, thereby uniformly conveying the material on the conveying belt 11.
[0037] Preferably, the left and right side panels of the conveying bin 21 are equipped with cleaning doors that are easy to open and close, so that the material blocked on the screen plate 22 and the metal impurities adsorbed on the magnetic suction plate 25 can be cleaned by opening the cleaning doors on the left or right side panels of the conveying bin 21.
[0038] like Figures 1-4 As shown, a pair of mounting rods 26 are fixedly connected to the outer walls of the front and rear side panels of the conveying bin 21, and the mounting rods 26 are used to support the conveying bin 21. A pair of support rods 27 are fixedly connected to a pair of mounting plates 13, and the support rods 27 are used to support the mounting rods 26.
[0039] like Figure 4 Combination Figure 6 As shown, a pair of support rods 27 are provided with a pair of mounting slots 28, and the ends of a pair of mounting rods 26 away from the material conveying bin 21 are respectively slidably connected to the pair of mounting slots 28, so that the mounting rods 26 can move up and down when installed in the mounting slots 28.
[0040] like Figure 4 Combination Figure 6 As shown, a compression spring 29 is installed in the mounting groove 28. The compression spring 29 is sleeved on the side wall of the part of the mounting rod 26 placed inside the mounting groove 28. When the mounting rod 26 slides in the mounting groove 28, it can compress the compression spring 29, which then exerts an upward elastic force on the mounting rod 26. When material enters the conveying hopper 21 and is screened by the screen plate 22, if there is a lot of material, the conveying hopper 21 can move the mounting rod 26 downward under the action of gravity. When the material in the conveying hopper 21 decreases due to screening by the screen plate 22, the mounting rod 26 can move upward under the action of the compression spring 29. As the material continuously feeds into and out of the conveying hopper 21, the gravity of the material changes. Under the extension and contraction of the compression spring 29, the mounting rod 26 can drive the conveying hopper 21 to move up and down, causing the conveying hopper 21 to vibrate. This vibration of the conveying hopper 21 improves the screening effect of the screen plate 22 on the material.
[0041] like Figure 4 Combination Figure 6 As shown, a limiting plate 210 is fixedly connected to the side wall of the mounting rod 26 within the mounting groove 28, and a limiting ring 211 is fixedly connected to the inner side wall at the upper end of the mounting groove 28. The range of movement of the mounting rod 26 within the mounting groove 28 is limited by the cooperation of the limiting plate 210 and the limiting ring 211.
[0042] like Figures 1-4As shown, the bottom of the left side wall plate of the material conveying bin 21 is provided with a material blocking strip 212, which can be stretched and contracted with the up-down movement of the material conveying bin 21, so that the material conveying bin 21 can limit the falling of the material from the material conveying bin 21. The bottom of the right side wall plate of the material conveying bin 21 is provided with a material outlet 213, so that the material screened by the screen plate 22 and guided by the guide plate 24 falls on the conveying belt 11 through the material outlet 213 for conveying.
[0043] In use, the material is added through the upper end of the material conveying bin 21, and the material entering the material conveying bin 21 is screened by the screen plate 22. Due to the increase of the gravity of the material conveying bin 21 under the action of the material, a pair of mounting rods 26 drives the material conveying bin 21 to move downward, and the mounting rod 26 can compress the compression spring 29 when moving downward. When the material is screened through the screen hole 23, the gravity in the material conveying bin 21 changes constantly due to the continuous feeding and discharging of the material in the material conveying bin 21, so that the material conveying bin 21 moves up and down under the action of the compression spring 29, so as to vibrate the material conveying bin 21, which can improve the screening effect of the material by the screen plate 22. The material screened by the screen hole 23 on the screen plate 22 falls on the guide plate 24, and is uniformly distributed on the conveying belt 11 after being guided by the guide plate 24, so as to uniformly distribute the material on the conveying belt 11. At the same time, the magnetic plate 25 can treat the metal impurities in the material when the material flows on the guide plate 24.
[0044] It is apparent for those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and thus can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Accordingly, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced therein. Any reference signs in the claims should not be regarded as limiting the claims to which they belong.
