Description

Technical Field

[0001] The utility model relates to the technical field of belt scales, in particular to a residual material cleaning device for belt scales. Background Art

[0002] A belt scale is an automatic weighing device that continuously weighs bulk materials on a conveyor belt without subdividing the mass or interrupting the movement of the conveyor belt. The weighing bridge of an electronic belt scale is installed on the conveyor frame. When the material passes through, the metering roller detects the weight of the material on the belt conveyor and acts on the weighing sensor through a lever, generating a voltage signal proportional to the belt load. There is a weighing sensor installed on the weighing bridge on the belt scale. When working, the weight of the material on the belt is sent to the weighing instrument. At the same time, the speed signal of the belt conveyor from the speed sensor is also sent to the weighing instrument. The instrument integrates the speed signal and the weighing signal to obtain the instantaneous flow rate and cumulative amount. The speed sensor is directly connected to the large-diameter speed measuring roller and provides a series of pulses. Each pulse represents a belt motion unit, and the frequency of the pulse is proportional to the belt speed. The weighing instrument receives signals from the weighing sensor and the speed sensor, and obtains an instantaneous flow value and cumulative weight value through integration operation, and displays them separately.

[0003] In long-term practical applications, it is found that when electronic belt scales are used to transport materials, due to the large variety of materials, different properties, and many of them are sticky and easy to stick to the weighing area of ​​the belt scale. When a large amount of material is adhered to the weighing area of ​​the belt scale, it will be subjected to an additional force during weighing, resulting in weighing errors, which directly affects the measurement accuracy of the material.

[0040] See also Figure 1-6 A belt scale residual material cleaning device comprises a support base 1, a rotating shaft 2 rotatably arranged at both ends of the support base 1, a belt body 4 sleeved on the rotating shaft 2, and a first motor 3 arranged on the support base 1 and used to drive one of the rotating shafts 2 to rotate, and also comprises:

[0041] The cleaning mechanism 5 is arranged below the belt body 4 and cleans the belt body 4. It includes two scraper plates 52 in contact with the surface of the belt body 4 and a replacement component arranged on the scraper plates 52 and used to replace the two scraper plates 52 for alternate operation.

[0043] In one embodiment, the replacement assembly includes:

[0044] The tooth plate 55 is disposed on one side of the scraper plate 52 and drives the scraper plate 52 to move up and down;

[0045] The gear 510 is rotatably disposed between the two tooth plates 55 and meshedly connected with the tooth plates 55, and is used to drive the two tooth plates 55 to move in opposite directions;

[0046] A second motor 54 is connected to the gear 510 and is used to drive the gear 510 to rotate;

[0047] The mounting member is disposed on the tooth plate 55 and is used to mount the scraper plate 52 on the tooth plate 55 .

[0048] In one embodiment, the mounting member comprises:

[0049] A mounting block 58 connected to one end of the tooth plate 55 close to the scraper plate 52 and allowing the scraper plate 52 to pass through;
