AI Technical Summary
Existing concrete production raw material conveying devices are prone to damage during use due to sand and gravel clumping causing friction with the equipment sidewalls.
The system employs a processing device and an interception device. The processing device uses a crushing wheel to cut clumps of sand and gravel, while the interception device uses an interception rod to block larger sand, gravel, or debris, thus solving the problems of sand and gravel clumping and large particles.
This effectively avoids friction damage to the conveying device caused by sand and gravel agglomeration and large particles during use, thus improving the device's service life and operational stability.

[0024] Specifically, the first motor 33 is fixedly connected to the upper surface of the support frame 31. The first motor 33 is located on both sides of the sliding end of the adjusting frame 37. The first motor 33 can cooperate with the support frame 31 to achieve the purpose of fixing the first motor 33.

[0026] In this embodiment, gear 32 can cooperate with the toothed plate at the sliding end of the first motor 33 and the adjusting frame 37 to achieve the purpose of adjusting the lifting of the adjusting frame 37. The first motor 33 is a stepper motor.
[0027] In this embodiment: the surface of the main frame 1 is provided with an interception device 4, which includes a baffle plate 44. The baffle plate 44 is fixedly connected to the upper surface of the main frame 1 and is placed on the upper surface of the conveyor belt 2. The baffle plate 44 can cooperate with the main frame 1 to achieve the purpose of supporting the baffle plate 44.
[0028] Specifically, the surface of the baffle plate 44 is provided with two sets of placement openings 45.

[0033] Working Principle: By setting up processing device 3, when the operator needs to crush lumpy sand and gravel, the operator starts the first motor 33.

The positioning rod 41 is inserted into the inside of the threaded hole 46. The worker rotates the positioning rod 41, and the positioning rod 41 is threaded into the inside of the threaded hole 46. The first intercepting rod 42 and the second intercepting rod 43 cannot slide left or right. When larger sand or debris comes into contact with the first intercepting rod 42 and the second intercepting rod 43, the first intercepting rod 42 and the second intercepting rod 43 block the larger sand or debris. The gap between the first intercepting rod 42 and the second intercepting rod 43 allows fine sand to pass through normally. The second intercepting rod 43 can push down the accumulated sand and gravel. The accumulated sand and gravel slide to both sides due to obstruction. By setting up the intercepting device 4, sand and gravel can be effectively intercepted, avoiding larger sand or debris from affecting the normal operation of the processing device 3, thereby reducing the possibility of damage to the processing device 3.
