Description

Technical Field

[0001] This utility model relates to the field of belt weighing machine technology, and in particular to a belt weighing machine that is easy to load and unload. Background Technology

[0002] A belt weighing machine, also known as a belt scale or electronic belt scale, is an automated device used to continuously measure the weight of bulk materials on a conveyor belt. Its core function is to calculate the instantaneous flow rate and cumulative weight of materials by monitoring the belt load and operating speed in real time. It is widely used in metering, batching, and production control scenarios in industries such as coal, chemical, metallurgy, grain, and ports.

[0003] Traditional belt weighing machines have fixed loading and unloading port heights, making them difficult to adapt to material transport equipment of different heights. They require frequent manual adjustments or the use of auxiliary tools, resulting in low efficiency and safety hazards. Furthermore, materials are prone to scattering or shifting when entering the weighing area, leading to inaccurate weighing and requiring manual intervention. Therefore, there is a need to propose a belt weighing machine that facilitates loading and unloading. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a belt weighing machine that facilitates loading and unloading.

Each bevel gear has a threaded rod on its inner ring. The bottom ends of the two threaded rods extend through to the bottom surface of the support plate and are threadedly connected to the same support leg. Each support leg has two movable wheels on its bottom surface.

[0022] Each threaded plate 5 has a push plate 6 on its bottom surface. The bottom surface of the threaded plate 5 and the top surface of the push plate 6 are fixedly connected. The bottom surface of the push plate 6 is close to but not touching the top surface of the belt weighing machine body 1, which facilitates the guidance of materials without hindering the conveying operation of the belt weighing machine body 1. A fixing plate 7 is provided on the left side of the U-shaped frame 2. The left side of the U-shaped frame 2 and the right side of the fixing plate 7 are fixedly connected. A motor 8 is provided on the top surface of the fixing plate 7. The top surface of the fixing plate 7 and the bottom surface of the motor 8 are fixedly connected. The output end of motor 8 extends through to the bottom surface of fixed plate 7 and is provided with cylinder push rod 9. The output end of motor 8 is rotatably connected to fixed plate 7, and the output end of motor 8 is fixedly connected to the top surface of cylinder push rod 9. The output end of cylinder push rod 9 is provided with rake frame 10, and the output end of cylinder push rod 9 is fixedly connected to the top surface of rake frame 10. The bottom surface of belt weighing machine body 1 is provided with two support frames 11, and the bottom surface of belt weighing machine body 1 is fixedly connected to the top surface of support frame 11.

[0023] An L-shaped support frame 12 is provided on the right side of a support frame 11 located at the front. The support frame 11 and the L-shaped support frame 12 are fixedly connected. A motor 13 is provided on the right side of the L-shaped support frame 12. The right side of the L-shaped support frame 12 and the left side of the motor 13 are fixedly connected. A pulley 14 is rotatably provided on the right side of both support frames 11. The output end of the motor 13 extends through to the left side of the L-shaped support frame 12 and is fixedly connected to the pulley 14 located at the front. The output end of the motor 13 can drive the pulley 14 to rotate. The outer ring of the two pulleys 14 is provided with the same transmission belt 15 to facilitate transmission among the three. A rotating rod 16 is provided on the inner ring of each pulley 14. The inner ring of the pulley 14 and the outer ring of the rotating rod 16 are fixedly connected.

[0025] In this embodiment, when adjusting the height of the belt weighing machine body 1 using this device, motor 3 13 needs to be operated. The output end of motor 3 13 drives a pulley 14 located at the front to rotate. The rotation of pulley 14 can cooperate with the other pulley 14 and the transmission belt 15 to transmit power, thereby causing the two rotating rods 16 to rotate simultaneously. The rotation of the rotating rods 16 can drive the first bevel gear 17 to rotate. The first bevel gear 17 and the second bevel gear 19 are meshed. Therefore, the rotation of the first bevel gear 17 can drive the second bevel gear 19 to rotate. The rotation of the second bevel gear 19 can drive the threaded rod 20 to rotate, thus enabling... The support leg 21 moves up and down along the threaded rod 20, thereby adjusting the height of the belt weighing machine body 1 for easy loading and unloading. When the material is too scattered, motor 3 can be operated. The output end of motor 3 can drive the bidirectional screw 4 to rotate. The rotation of the bidirectional screw 4 can drive the two threaded plates 5 to move closer or further apart, thereby driving the two push plates 6 to move closer together, thus guiding the material. When the material is too concentrated in one position, motor 8 can be operated to drive the cylinder push rod 9 to rotate. When the cylinder push rod 9 drives the rake frame 10 to move downward, the rake frame 10 disperses the material.
