Description

Technical Field

[0001] The present application relates to the technical field of belt conveyors, and in particular to a mobile high-precision intelligent belt weighing feeder. Background Art

[0002] When loading or transporting bulk materials, it is usually necessary to use a belt conveyor for assistance to reduce the labor intensity of workers and improve the transfer efficiency of bulk materials.

[0003] The existing belt conveyor includes a conveying support, a conveying belt, and a conveying motor. The conveying belt is rotatably arranged on the conveying support, and the conveying motor is fixedly arranged on the conveying support and used to drive the conveying belt to rotate. During use, the bulk materials are poured onto the conveying belt, and the conveying motor drives the conveying belt to rotate. The conveying belt conveys the bulk materials during rotation to achieve the rapid transfer of bulk materials.

[0004] Although conveying bulk materials by the conveying belt helps with the transfer of bulk materials, it is difficult to accurately measure the transfer weight of bulk materials, which easily leads to the transfer weight of bulk materials exceeding the preset weight. Utility Model Content

[0005] In order to accurately measure the transfer weight of bulk materials during the conveying process of the conveying belt, the present application provides a mobile high-precision intelligent belt weighing feeder.

[0006] The mobile high-precision intelligent belt weighing feeder provided by the present application adopts the following technical solutions:

[0007] A mobile high-precision intelligent belt weighing feeder includes a conveying support, a conveying belt, and a weighing assembly. The weighing assembly includes a weighing roller, a weighing sensor, a speed sensor, a controller, and a digital display panel;

[0008] The conveying belt is rotatably arranged on the conveying support through two conveying rollers;

[0009] At least one weighing roller is provided and arranged along the conveying direction of the conveying belt. The weighing roller is located inside the conveying belt and abuts against the conveying belt;

[0010] At least one group of weighing sensors is provided and corresponds to the weighing roller one by one. The number of each group of weighing sensors is two. The two weighing sensors are respectively arranged at both ends of the weighing roller. One end of the weighing sensor is fixedly connected to the conveying support, and the other end is rotatably connected to the end of the weighing roller. The weighing sensor is used to output a weight signal;

[0011] The speed sensor is located inside the conveying belt and fixedly connected to the conveying support. The probe of the speed sensor faces the conveying belt. The speed sensor is used to output a speed signal;

[0012] The controller and the digital display dial are both fixedly installed on the conveying support. The controller is electrically connected to the weighing sensor, the speed sensor, and the digital display dial respectively. The controller responds to the weight signal and the speed signal and is used to control the digital display dial to display the weight value in real time.

[0013] By adopting the above technical solution, the bulk materials are poured onto the conveying belt, and the conveying belt is rotated to convey and transfer the bulk materials. The bulk materials press on the conveying belt. When the bulk materials pass through the weighing roller, the bulk materials transfer the gravity to the conveying roller through the conveying belt. After being pressed, the conveying roller can transfer the pressure to the weighing sensor, enabling the weighing sensor to measure the weight of the bulk materials on the conveying belt; the speed sensor can measure the moving speed of the conveying belt; the controller receives the weight signal and the speed signal, and calculates the total weight of the bulk materials conveyed by the conveying belt based on the weight signal and the speed signal. The controller controls the digital display dial to display the weight value in real time, so that the transfer weight of the bulk materials can be accurately measured during the conveying process of the conveying belt.

[0014] Optionally, a hopper is arranged above the feeding end of the conveying belt. The hopper is conical and fixedly connected to the conveying support.

[0015] By adopting the above technical solution, through the conical hopper, it is convenient to pour the bulk materials onto the conveying belt, making it difficult for the bulk materials to spill outside the conveying belt.

[0016] Optionally, a guiding plate is fixedly connected to the discharging end of the hopper. The guiding plate is located on one side of the hopper close to the discharging end of the conveying belt.

[0017] By adopting the above technical solution, by setting the guiding plate, the bulk materials can be moved out of the hopper along the conveying direction of the conveying belt, making it difficult for the bulk materials to spill from both sides of the conveying belt when moving out of the hopper.

[0018] Optionally, retaining bars are fixedly installed on both sides of the conveying belt in the conveying direction.

[0019] By adopting the above technical solution, the retaining bars can prevent the bulk materials from spilling from both sides of the conveying belt, enabling the bulk materials to be stably conveyed.

[0020] Optionally, moving wheels are arranged on the conveying support.

[0021] By adopting the above technical solution, it is convenient to move the conveying support to any bulk material transfer position through the moving wheels, making the use of the feeder more flexible.

[0022] Optionally, there are more than three telescopic legs on the conveying support, and more than three telescopic legs are on different straight lines.

[0023] By adopting the above technical solution, the telescopic support legs can be adjusted in length to stably support the conveying bracket on the ground. On the one hand, it is beneficial to the stable transfer of bulk materials, and on the other hand, it helps to adjust the conveying belt to a fixed conveying angle.

[0024] Optionally, a cleaning assembly is provided on the conveying bracket. The cleaning assembly includes an inner cleaning bracket, an inner cleaning brush plate, an outer cleaning bracket, and an outer cleaning brush plate.

[0025] The inner cleaning bracket is arranged inside the conveying belt and is connected to the conveying bracket. The inner cleaning brush plate is arranged on the inner cleaning bracket and abuts against the inner surface of the conveying belt.

[0026] The outer cleaning bracket is arranged below the discharging end of the conveying belt and is connected to the conveying bracket. The outer cleaning brush plate is arranged on the outer cleaning bracket and abuts against the outer surface of the conveying belt.

[0027] By adopting the above technical solution, when the conveying belt rotates, the inner cleaning brush plate cleans the inner side of the conveying belt, and the outer cleaning brush plate cleans the outer side of the conveying belt to prevent sundries from adhering to the conveying belt and affecting the measurement of the weighing sensor.

[0028] Optionally, the inner cleaning bracket is slidably arranged on the conveying bracket along the direction of approaching or departing from the side of the conveying belt. The inner cleaning brush plate is slidably inserted into the inner cleaning bracket, and the insertion direction is the moving direction of the conveying belt.

[0029] By adopting the above technical solution, by sliding the inner cleaning bracket, the inner cleaning brush plate can be moved out of the conveying belt, so that the inner cleaning brush plate is convenient to be pulled out from the inner cleaning bracket, and thus the inner cleaning brush plate is convenient to be replaced.

[0030] Optionally, the outer cleaning bracket is fixedly connected with a hinge shaft. A hinge sleeve is rotatably sleeved on the hinge shaft. The hinge sleeve is fixedly connected with the conveying bracket. A chute is formed on the side wall of the hinge shaft. A clamping block is slidably arranged in the chute. A spring for driving the clamping block to slide out of the chute is arranged between the clamping block and the bottom of the chute. A clamping groove is formed on the inner side wall of the hinge sleeve. The clamping block is clamped in the clamping groove. One end of a pull rope slidably penetrates through the end of the hinge shaft. One end of the pull rope penetrates into the chute and is fixedly connected with the clamping block. The outer cleaning brush plate is slidably inserted into the outer cleaning bracket, and the insertion direction is the moving direction of the conveying belt.

[0031] By adopting the above technical solution, pulling the pull rope enables the clamping block to squeeze the spring and slide into the chute, so that the fixation between the hinge shaft and the hinge sleeve is released. Rotating the outer cleaning bracket makes the outer cleaning brush plate turn away from the conveying belt, so that the outer cleaning brush plate is convenient to be pulled out from the outer cleaning bracket, and thus the outer cleaning brush plate is convenient to be replaced.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. By setting up weighing rollers, weighing sensors, speed sensors, controllers, and digital display dials, the transfer weight of bulk materials can be accurately measured during the conveying process of the conveyor belt.

[0034] 2. By setting up an aggregate hopper, a material guiding plate, and a baffle strip, it is made difficult for bulk materials to scatter from the conveyor belt.

[0035] 3. By setting up an inner cleaning bracket, an inner cleaning brush, an outer cleaning bracket, and an outer cleaning brush, both the inner and outer sides of the conveyor belt can be cleaned. BRIEF DESCRIPTION OF THE DRAWINGS
