Description

Technical Field

[0001] This utility model relates to the field of weighbridge technology, specifically to an electronic weighbridge device with a simple, reliable, and easy-to-maintain structure and three-sided baffles with ramps. Background Technology

[0002] In waste sorting and weighing scenarios, existing electronic weighbridges have complex structures and intricate connections between components. Their pallets are flat without ramps, and the platform is quite high, making it difficult to push in a 240L waste bin. Furthermore, due to the lack of baffles, the bins are prone to shifting.

[0003] The current sensors typically consist of one or four sensors. A single sensor, with its limited force distribution, is prone to instability under slight external forces, easily damaged over time, and its weighing accuracy is difficult to guarantee. While four sensors attempt to distribute the force, the excessive number results in a bulky and cumbersome overall structure. Furthermore, the high precision required for coordination between sensors leads to poor accuracy in actual use, and the debugging and maintenance process is cumbersome. In addition, the existing sensor installation method increases the height of the countertop, further complicating the placement of trash cans.

[0004] The connection design between the keel and the pallet is unreasonable, resulting in weak resistance to deformation of the pallet, which is prone to tilting after long-term load-bearing. The base structure design is redundant, lacking the unique top-view opening design of two I-shaped sections combined with left and right folding plates. During installation, multiple parts need to be disassembled to expose the expansion bolt holes, making installation impossible for a single person and requiring multiple people to work together, resulting in extremely low efficiency.

[0005] Furthermore, during installation, multiple people collaborate to disassemble the base components. After securing the base with expansion screws, one or four sensors are connected to the tray in a traditional manner. This installation method results in a relatively high platform height. During weighing, it is difficult to lift and place the trash can, and it is prone to shifting. A single sensor experiences frequent data fluctuations due to unstable force, and four sensors suffer from accuracy deviations due to coordination issues. Maintenance requires disassembling a large number of connecting parts, which is time-consuming and labor-intensive. The unreasonable sensor installation method increases the platform height, making it more difficult and time-consuming to place the trash can. To address this, we propose an electronic weighbridge device with a simple, reliable, and easy-to-maintain structure, featuring a ramp and three-sided baffle. Utility Model Content

[0006] The purpose of this utility model is to provide an electronic weighbridge device with a simple, reliable, and easy-to-maintain structure and three-sided baffles with ramps, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a simple, reliable, and easy-to-maintain electronic weighbridge device with ramps and three-sided baffles, comprising a base mechanism and a support mechanism. Three sets of interconnected baffles are fixedly installed at the top edge of the support mechanism. An inclined ramp plate is fixedly connected to one end of the opening of the support mechanism. Two sets of centrally symmetrical weighing sensors are fixedly installed on the top of the base mechanism. A first mounting bracket is fixedly installed on the baffles. The weighing sensors are fixedly connected to the first mounting bracket. The bottom of the weighing sensors and the pressure head are fixedly connected to the base mechanism and the support mechanism by fixing bolts.

[0008] Furthermore, the base mechanism includes a base frame, a second mounting frame, and a first connecting keel. The base frame is configured as two sets, and the two sets of base frames are fixedly connected by two sets of I-shaped first connecting keels. The two sets of base frames are fixedly mounted with centrally symmetrical second mounting frames.

[0009] Furthermore, the supporting mechanism includes a pallet, a second connecting keel, and a third connecting keel. The bottom of the pallet is fixedly connected to four sets of I-shaped third connecting keels and three sets of I-shaped second connecting keels. Multiple sets of baffles are fixedly installed on the top of the pallet, and the ramp plate is fixedly connected to an opening on one side of the pallet.

[0010] Furthermore, multiple sets of mounting slots are provided on the first connecting keel, and limit posts are fixedly installed inside the mounting slots.

[0011] Furthermore, the slope plate has an inclination angle of 45°.

[0012] Furthermore, the bearing mechanism, baffle, and ramp are all made of 304 stainless steel. The pallet is 690cm long, 660cm wide, 63mm high at the top, and 30cm high at the baffle.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The weighing sensor in this utility model is fixedly connected to the base mechanism and the first mounting bracket by fixing bolts. This setting can effectively reduce the top height of the bearing mechanism and cooperate with the inclined ramp plate to reduce the platform height, making it easier to push the trash can in.

[0015] 2. The two sets of weighing sensors are centrally symmetrically arranged to avoid the problems of unstable force, easy damage, and low accuracy of a single sensor, as well as the problems of poor accuracy, bulkiness, and complex maintenance of four sensors. The three sets of baffles can prevent the trash can from being pushed too far off the top of the supporting mechanism when it is put in.

[0016] 3. Moreover, the base mechanism is an integrated design, which can be directly fixed by multiple expansion screws during installation and disassembly. It is also lightweight and can be installed and disassembled by a single person, improving installation efficiency.

[0017] 4. Moreover, the first connecting keel can ensure that the base mechanism will not deform during use, and the second and third connecting keels, with their four horizontal and three vertical I-beam folding parts, enhance the tray's resistance to deformation to a certain extent, ensuring stable and non-tilting weighing, and facilitating high-precision weighing in conjunction with intelligent controller algorithms.

[0018] 5. Moreover, the pallet is 690cm long and 660cm wide, with a top height of 63mm and a baffle height of 30cm, which allows a 240L trash can to be pushed in and precisely positioned, reducing workload. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4This utility model provides a technical solution: a simple, reliable, and easy-to-maintain electronic weighbridge device with a ramp and three-sided baffles, including a base mechanism 1 and a support mechanism 3. Three sets of interconnected baffles 4 are fixedly installed at the top edge of the support mechanism 3. An inclined ramp 6 is fixedly connected to one end of the opening of the support mechanism 3. The ramp 6 has an inclination angle of 45°. Two sets of centrally symmetrical weighing sensors 2 are fixedly installed on the top of the base mechanism 1. A first mounting bracket 5 is fixedly installed on the baffle 4. The weighing sensor 2 is fixedly connected to the first mounting bracket 5. The bottom of the weighing sensor 2 and the pressure head are fixedly connected to the base mechanism 1 and the support mechanism 3 by fixing bolts 7.

[0026] The base mechanism 1 can be fixedly installed using expansion screws. The two sets of weighing sensors 2 are centrally symmetrically arranged to avoid the problems of unstable force, easy damage, and low accuracy of a single sensor, as well as the problems of poor accuracy, bulkiness, and complex maintenance of four sensors. The three sets of baffles 4 can prevent the trash can from being pushed too far off the support mechanism 3 when it is placed in. The weighing sensors 2, the first mounting frame 5, and the base mechanism 1 are connected by multiple sets of fixing bolts 7, which facilitates the disassembly and maintenance of the entire device. The baffles 4 and the support mechanism 3 are connected by the upwardly extending first mounting frame 5, which can reduce the height of the support mechanism 3. In conjunction with the 45° inclined ramp plate 6, it is convenient to push the trash can onto the support mechanism 3 for weighing.

[0027] Please see Figure 1 and Figure 2 The base mechanism 1 includes a base frame 8, a second mounting frame 9, and a first connecting keel 10. The base frame 8 is configured as two sets, and the two sets of base frames 8 are fixedly connected by two sets of I-shaped first connecting keels 10. The two sets of base frames 8 are fixedly installed with centrally symmetrical second mounting frames 9.

[0028] The first connecting keel 10 can fix the two sets of base frames 8 together. The second mounting frame 9 is a protrusion, which facilitates the fixed installation of the weighing sensor 2. Moreover, the second mounting frame 9 and the weighing sensor 2 are both centrally symmetrical, which makes it easy to weigh the garbage can on the bearing mechanism 3 evenly.

[0029] Please see Figure 1 , Figure 3 and Figure 4 The supporting mechanism 3 includes a tray 11, a second connecting keel 12 and a third connecting keel 13. The bottom of the tray 11 is fixedly connected to four sets of I-shaped third connecting keels 13 and three sets of I-shaped second connecting keels 12. Multiple sets of baffles 4 are fixedly installed on the top of the tray 11. The ramp plate 6 is fixedly connected to the opening on one side of the tray 11.

[0030] The second connecting keel 12 and the third connecting keel 13, with their four horizontal and three vertical I-beam folding components, enhance the deformation resistance of the pallet 11 to a certain extent, ensuring stable and non-tilting weighing, and facilitating high-precision weighing in conjunction with the intelligent controller algorithm.

[0031] Please see Figure 1 and Figure 2 The first connecting keel 10 has multiple sets of mounting slots 14. Limiting posts 15 are fixedly installed inside the mounting slots 14. The limiting posts 15 are fixed inside the mounting slots 14 at the four corners of the first connecting keel 10 by screws. The gap between the top of the limiting post 15 and the bottom of the tray 11 is set to 15cm, which can effectively prevent mechanical damage.

[0032] Please see Figures 1-4 The supporting mechanism 3, baffle 4, and ramp 6 are all made of 304 stainless steel. The length of the pallet 11 is 690cm, the width is 660cm, the top height of the pallet 11 is 63mm, and the height of the baffle 4 is 30cm. The 304 stainless steel components can prevent the garbage inside the trash can from corroding the components. Moreover, the length of the pallet 11 is 690cm, the width is 660cm, the top height of the pallet 11 is 63mm, and the height of the baffle 4 is 30cm, which makes it easy to push the 240L trash can in and accurately limit its position, reducing the workload.

[0033] In use, the base mechanism 1 is firstly fixed in place using expansion screws. The two sets of load cells 2 are centrally symmetrically arranged, avoiding the problems of unstable force, easy damage, and low accuracy of a single sensor, and the poor accuracy, bulkiness, and complex maintenance of four sensors. The three sets of baffles 4 prevent the trash can from being pushed excessively and detaching from the supporting mechanism 3 when placed in the bin. The load cells 2, the first mounting bracket 5, and the base mechanism 1 are connected by multiple sets of fixing bolts 7, facilitating disassembly and maintenance of the entire device. The baffles 4 and the supporting mechanism 3 are connected by the upwardly extending first mounting bracket 5, reducing the height of the supporting mechanism 3. This, combined with the 45° inclined ramp 6, facilitates pushing the trash can onto the supporting mechanism 3 for weighing. The connecting keel 10 can fix the two sets of base frames 8 together. The second mounting frame 9 is designed with a protrusion to facilitate the fixed installation of the weighing sensor 2. Moreover, the second mounting frame 9 and the weighing sensor 2 are both centrally symmetrically arranged, which can facilitate the uniform weighing of the garbage can on the bearing mechanism 3. The second connecting keel 12 and the third connecting keel 13 use four horizontal and three vertical I-beam folding parts to enhance the deformation resistance of the tray 11 to a certain extent, ensuring stable and non-tilting weighing, which is convenient for high-precision weighing with the intelligent controller algorithm. The tray 11 is 690cm long, 660cm wide, and the top height of the tray 11 is 63mm. The height of the baffle 4 is 30cm, which can facilitate the pushing of the 240L garbage can and accurately limit its position, reducing the workload.
