Description

Technical Field

[0001] The utility model relates to the technical field of concrete raw material transportation, in particular to a sand and gravel transportation production line with a dustproof device. Background Art

[0002] During the construction of buildings, bridges and other projects, concrete raw materials have fixed storage places. In order to reduce manpower, concrete raw material conveyor belts are often used to transport concrete from the storage place to the mixing place for operation.

[0003] The Chinese patent application number CN201910931609.3 discloses a sand and gravel conveying device, including a frame, an active roller, a driven roller, a tensioning assembly, a roller assembly, a driving assembly and a belt, wherein the active roller and the driven roller are rotatably fixed at both ends of the frame through bearings, one high and one low, the driving assembly is fixed on the frame and drives the active roller to rotate, the belt is obliquely sleeved outside the active roller and the driven roller, several groups of the roller assemblies are fixed on the frame in sequence and lift the front and rear sides of the upper belt so that the upper belt is in the shape of a pocket with a sunken center, the tensioning assembly is fixed on both sides of one end of the frame close to the driven roller and adjusts the driven roller away from the active roller to tension the belt, and the sand and gravel are transmitted by using a belt with a V-shaped pattern, and the roller assembly is used to support the belt so that it is in the shape of a pocket with a sunken center, so as to hold and transport more sand and gravel, and prevent sand and gravel from rolling off the belt.

[0004] However, the above cases still have certain defects in practical application. During the transportation of sand and gravel raw materials, the shaking of the belt during operation can easily cause a large amount of dust to overflow. When the wind is strong outdoors, the dust will also pollute the construction site, causing harm to human respiratory health and is not conducive to production and use. Therefore, it is necessary to propose a sand and gravel conveying production line with a dust prevention device to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a sand and gravel conveying production line with a dustproof device, which has the effect of preventing dust.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a sand and gravel conveying production line with a dust-proof device, comprising a base plate, a bracket and a sand and gravel conveyor belt connected to the bracket are arranged at the upper end of the base plate, a feeding bin and a dust-proof mechanism are arranged at the upper end of the sand and gravel conveyor belt, the dust-proof mechanism comprises a dust-proof bin arranged at the upper end of the sand and gravel conveyor belt, a water tank is arranged at the upper end of the base plate, a fan structure is arranged on the dust-proof bin, a dust conveying pipe connected to the water tank is arranged on the fan structure, and dust reduction structures are arranged at the left and right ends of the sand and gravel conveyor belt.

[0007] By adopting the above technical scheme, sand and gravel enter the sand and gravel conveyor belt from the feed bin and are transported forward. During the transportation process, the dust prevention bin can prevent the generated dust from overflowing in large quantities. At the same time, the fan structure is driven to absorb the dust and send it into the water tank through the dust conveying pipe to process the dust. The setting of the dust reduction structure can prevent dust from overflowing from both sides at the same time, so that the device can achieve better dust prevention effect.

[0008] The utility model is further configured as follows: the fan structure includes a dust suction bin installed on the dustproof bin, a connecting plate is installed in the dust suction bin, two suction fans are arranged on the connecting plate, a first transmission member is arranged between the two suction fans, and a first motor connected to one suction fan is also arranged on the connecting plate.

[0009] By adopting the above technical solution, the two fans are controlled to rotate by the linkage of the first motor and the first transmission member, so that the generated dust is absorbed upward and enters the water tank through the dust collection bin and the dust conveying pipe to reduce dust.

[0010] The utility model is further configured as follows: a dust filter is provided at the bottom of the dust collection bin.

[0011] By adopting the above technical solution, the dust filter is arranged to prevent the damage to the fan and its structure caused by the suction of large volumes of sand and gravel.

[0014] The utility model is further configured as follows: the first transmission member and the second transmission member each include two synchronous wheels, and a synchronous belt is provided between the two synchronous wheels.

[0015] By adopting the above technical solution, when one fan rotates, the synchronous wheel and the synchronous belt drive the two fans to rotate. When the output roller of the sand and gravel conveyor belt rotates, the synchronous wheel and the synchronous belt drive the rotating shaft on the scattering blades to rotate at the same time, so that the scattering blades rotate accordingly.

[0016] The utility model is further configured as follows: a plurality of sand and gravel conveying baffles are arranged at equal intervals on the surface of the sand and gravel conveyor belt.

[0017] By adopting the above technical solution and setting the sand and gravel conveying baffle, the sand and gravel conveying is made more stable and uniform.

[0018] The utility model is further configured as follows: the dust reduction structure includes a water pump installed on the upper end of the bottom plate, spray heads are provided at both ends above the sand and gravel conveyor belt, and a water pipe is connected between the water pump, the spray head and the water tank.

[0019] By adopting the above technical solution, the water pump is driven to make the water pipe draw clean water in the water tank and send it to the sprinkler head, so that the sprinkler head sprays both ends of the sand and gravel conveyor belt, thereby achieving an effective dust reduction effect.

[0020] The utility model is further configured as follows: a fixing frame connected to the spray head is provided on both the feed bin and the dustproof bin.

[0021] By adopting the above technical solution, the sprinkler head can be stably fixed on both sides of the sand and gravel conveyor belt by the fixing frame, so that dust reduction treatment can be carried out on the ends thereof.

[0022] The utility model is further configured as follows: a baffle is provided inside the water tank for dividing the water tank into two sections.

[0023] By adopting the above technical solution, the water tank is divided into two parts: a clean water tank and a sewage tank. The clean water tank is used for spraying and dust reduction, and the sewage tank is used for absorbing dust.

[0024] The utility model is further configured as follows: openings for the sand and gravel conveying baffle to pass through are provided on both sides of the bottom of the feed bin.

[0025] By adopting the above technical solution, the sand and gravel conveying baffle can smoothly pass through the feed bin and convey sand and gravel, and the structural design is more reasonable.

[0026] The beneficial effects of the utility model are:

[0027] 1. In the utility model, sand and gravel enter the sand and gravel conveyor belt from the feed bin and are transported forward. During the transportation process, the dust prevention bin can prevent the generated dust from overflowing in large quantities. At the same time, the fan structure is driven to absorb the dust and send it into the water tank through the dust conveying pipe to process the dust. The water pump is driven to draw clean water from the water tank through the water pipe and send it to the sprinkler head, so that the sprinkler head sprays the two ends of the sand and gravel conveyor belt, thereby achieving an effective dust reduction effect and making the dust prevention effect of the device better.

[0028] 2. The utility model drives the sand and gravel conveyor belt to operate through the second motor, and the second transmission member can control the rotation of the breaking blades to break up the sand and gravel entering the feed bin, which is convenient for the subsequent mixing and production of concrete.
