[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to the present utility model are shown in the drawings, not all of the structures. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] Please see Figs. 1-2 The present invention provides a belt conveyor with weighing function, which includes a support frame 1, a belt conveyor 2, a foot 21, a gravity sensor 22, a buffer assembly 23, an adjustment assembly 24, a drive wheel 25, a belt 26, an isolation assembly 27, and a cleaning assembly 3.

[0020] The support frame 1 is placed vertically on the ground. The weighing conveyor belt 2 is installed at the top of the support frame 1. The foot seat 21 is installed at the top of the support frame 1. The four weighing sensors 22 are respectively installed at the top of the foot seat 21. The buffer assembly 23 is installed at the top of the foot seat 21 and is connected to the four weighing sensors 22. The adjusting assembly 24 is installed at one end of the support frame 1. The two drive wheels 25 are respectively installed at both ends of the buffer assembly 23. The belt 26 is installed between the two drive wheels 25. The isolation assembly 27 is installed on the belt 26. The cleaning assembly 3 is installed at one end of the support frame 1.

[0021] Among them, the support frame 1 and the foot seat 21 provide support and provide a stable working environment for the weighing belt conveyor 2. The drive wheel 25 that is far away from the cleaning component 3 is equipped with a motor, which is responsible for providing power to the drive wheel 25 so that the belt 26 can operate.

[0022] Meanwhile, when the material enters the weighing belt conveyor 2, the material will first fall onto the belt 26 and be separated by the isolation component 27. Then the belt 26 and the buffer component 23 will sink due to the weight of the material, and the material will be weighed by the buffer component 23 and the gravity sensor 22. If the material is too heavy and exceeds the threshold that the belt 26 can bear, during the sinking weighing process, when the buffer component 23 sinks to the critical point of the bearing range of the belt 26 and the gravity sensor 22, the belt 26 will be unable to sink further. The buffer component 23 limits the sinking belt to prevent the material from damaging the belt 26 and the equipment itself.

[0023] Furthermore, during the operation of belt 26, due to the effects of prolonged tension and friction, belt 26 elongates. At this time, by adjusting component 24, the distance between the two pulleys on which belt 26 is installed is adjusted, thereby achieving the purpose of tensioning belt 26.

[0024] Furthermore, after the tension is adjusted, the adjusting component 24 will change the position of the belt 26. At this time, the position of the cleaning component 3 needs to be adjusted according to the new position of the belt 26. By rotating the cleaning component 3, the cleaning component 3 and the belt 26 come into contact with each other, thereby achieving the purpose of cleaning the belt 26.

[0025] In this embodiment, four limiting bolts 231 are respectively installed on the top of the foot base 21. Each guide rod group 232 has two guide rods. The two guide rod groups 232 are respectively installed on the top of the foot base 21 and are located on both sides of the foot base 21. Two structural frames 233 are installed corresponding to the two guide rod groups 232 and are respectively installed on the top of the guide rod groups 232. Four weighing rods 234 are respectively installed on the top of the foot base 21. The four weighing rods 234 correspond to four weighing sensors 22. The weighing rods 234 are located on one side of the weighing sensors 22 and are electrically connected to the four weighing sensors 22. Two fixing plates 235 are respectively installed on the top of the four weighing rods 234.

[0026] Among them, the structural frame 233 plays a supporting role, providing a stable working environment for the entire buffer assembly 23 when it sinks and weighs;

[0027] Meanwhile, when the material falls into the belt 26, the guide rod assembly 232 guides the belt 26 to sink downwards. The belt 26 drives the four weighing rods 234 to sink together. When the four weighing rods 234 sink, they will contact the corresponding gravity sensors 22, and the weighing work is completed. If the material is too heavy, the belt 26 and the four weighing rods 234 will continue to sink. When the weighing rods 234 sink to the critical point of the bearing range of the belt 26 and the gravity sensors 22, the limit bolts 231 will lock the weighing rods 234, so that the weighing rods 234 will no longer move. This will prevent the phenomenon of the material continuing to press down on the belt 26 after exceeding the threshold, thereby improving the service life of the belt.

[0028] Furthermore, there are two fixing plates 235. One end of the fixing plate 235 is provided with a long slot for cooperating with the adjusting component 24, thereby achieving the purpose of adjusting the tension of the belt 26.

[0029] In this embodiment, each rack assembly 241 has two racks, and the two rack assemblies 241 are respectively installed on both sides of the buffer assembly 24. The two gears 242 correspond one-to-one with the two rack assemblies 241, and the gears 242 are installed on the rack assemblies 241. The two gears 242 are connected to the drive wheel 25 near the cleaning assembly 3. The adjusting rod 243 is installed on one of the gears 242.

[0030] Two rack assemblies 241 are respectively installed on both sides of the two fixed plates 235 near the cleaning assembly 3. When the tension needs to be adjusted, the adjusting rod 243 is manually rotated, and the gear 242 rotates accordingly. At this time, the gear 242 drives the drive wheel 25 to start moving, and the belt 26 is also tensioned, thereby avoiding the phenomenon that the transmission efficiency is affected by the loose belt 26.

[0031] In this embodiment, multiple baffles 271 are rotatably mounted on the belt 26. Each limiting spring assembly 272 contains two limiting springs. The multiple limiting spring assemblies 272 correspond one-to-one with the multiple baffles 271. The two limiting springs in the limiting spring assembly 272 are respectively installed on both sides of the baffle 271. One end of the limiting spring in the limiting spring assembly 272 is connected to the belt 26, and the other end is connected to the baffle 271.

[0032] Among them, the isolation component 27 works in conjunction with the cleaning component 3, the belt 26 is always in working state, the cleaning component 3 will come into direct contact with the belt 26 during the cleaning process, at which time the cleaning component 3 remains stationary and the belt 26 continues to rotate;

[0033] Meanwhile, during the cleaning process of cleaning the surface of the belt 26, the cleaning component 3 first pushes down the baffle 271. At this time, the limit spring group 272 is in a stretched state. After the cleaning component 3 finishes cleaning the contact area with the belt 26, the limit spring group 272 on the belt 26 returns to its original state and pulls up the baffle 271 to achieve the function of isolating the material.

[0034] In this embodiment, the cleaning support frame 31 is installed at one end of the support frame 1 near the adjusting component 24, the slider 32 is slidably disposed on the cleaning support frame 31, the scraper 33 is installed at the top of the slider 32, the screw 34 is installed on the cleaning support frame 31, and one end of the screw 34 is connected to the slider 32, and the handle 34 is installed at the end of the screw 34 away from the slider 32.

[0035] When adjusting the tension of the belt 26 by adjusting component 24, the distance between the two drive wheels 25 will change accordingly, and the distance of the belt 26 driven by them will also change accordingly. At this time, it is necessary to adjust the position of cleaning component 3 in order to achieve a better cleaning effect on the surface of belt 26.

[0036] At the same time, the cleaning support frame 31 provides support and a stable working environment for the cleaning component 3;

[0037] Furthermore, when adjusting the position of the cleaning component 3, it is necessary to observe the position of the belt 26 before making the adjustment. Based on the positional relationship between the scraper 33 and the belt 26, turn the handle 35 to drive the screw 34 to rotate. At this time, the slider installed at one end of the screw 34 will also move. When the scraper 33 on the slider 32 reaches the desired contact state with the belt 26, stop turning the handle 34, thereby achieving the purpose of cleaning the dust and materials adhering to the surface of the belt 26.

[0038] In summary, this belt conveyor with weighing function includes a support frame 1, a weighing belt conveyor 2 for weighing materials, the weighing belt conveyor including feet 21, four weighing sensors 22, a buffer component 23 for reducing the pressure of material weighing on the belt, an adjusting component 24 for adjusting belt tension, two drive wheels 25, a belt 26, and an isolation component 27 for separating materials. This belt conveyor with weighing function, through the buffer component 23, avoids the phenomenon of the belt 26 continuing to be pressed down after the material exceeds the threshold, thereby improving the service life of the belt 26. The adjusting component 24 prevents the belt 26 from becoming loose due to prolonged operation, thus improving transmission efficiency and increasing belt life. The cleaning component 3 and the isolation component 27 work together to prevent material and dust from adhering to the belt during operation, accelerating belt wear and solving the problem of dust and material adhesion affecting the weighing structure. This further improves the service life and weighing accuracy of the belt 26 and reduces maintenance costs.
