Description

Technical Field

[0001] The utility model relates to the technical field of bucket wheel stacking and reclaiming operation equipment, in particular to a device for preventing dust from being raised by a bucket wheel machine's material dropping bucket. Background Art

[0002] Material conveying equipment has the advantages of advanced technology, high level of program control, outstanding environmental protection performance and less land occupation. It has been widely used in material storage and conveying systems in industries such as electricity, building materials, chemicals, mining, docks, coal and grain.

[0003] Bucket wheel stacker and reclaimer is a bulk material stacking and reclaiming equipment used in strip material yard operations. The equipment generates dust pollution during operation. As the country's environmental protection requirements become increasingly stringent, the dust prevention requirements for the material drop point are gradually increasing.

[0004] In order to prevent environmental pollution, dry coal sheds are now mostly used for bulk material transportation yards. However, after the yard is closed, the dust in the yard is serious and cannot be dispersed, which will increase the dust concentration in the material drop area and easily form a flammable and explosive place.

[0005] Therefore, those skilled in the art provide a device for preventing dust from being generated in the bucket of a bucket wheel machine to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] See also Figure 1-3 As shown;

[0030] The device for preventing dust from being generated by a bucket wheel machine drop bucket as described in Example 1 of the utility model comprises:

[0031] A hinge shaft 10, wherein the hinge shaft 10 is mounted on the coal drop support 40 via a support 11;

[0032] The buffer baffle 20 has one end rotatably connected to the hinge shaft 10, and the buffer baffle 20 plays a buffering role when the material falls from a high place; when the material falls from a high place, due to the large drop, the dust is large, and the impact force is large, the material first impacts the buffer baffle 20 here, because the buffer baffle 20 can rotate around the hinge shaft 10; when the buffer baffle 20 receives the impact force, the buffer baffle 20 slows down its rotation speed through the counterweight 31, and the material falls slowly at the same time; the height difference between the buffer baffle 20 and the lower material conveying point is small, so that dust can be reduced and the impact force can be reduced;

[0033] A counterweight arm 30 is provided with a counterweight 31 at one end of the counterweight arm 30, and the other end of the counterweight arm 30 is rotationally connected to the hinge shaft 10, and the counterweight arm 30 and the buffer baffle 20 rotate synchronously; a plurality of adjustment through holes 32 are provided on the end of the counterweight arm 30 away from the hinge shaft 10, and the counterweight 31 is arranged in one of the adjustment through holes 32.

[0034] Baffles 12 are installed on the hinge shaft 10 and at the two ends of the buffer baffle 20 to prevent the buffer baffle 20 from moving. Bushings 13 are installed on the hinge shaft 10 and at the outer sides of the two baffles 12. The bushings 13 are installed on the support 11. A gasket 14 is installed between the hinge shaft 10 and the bushing 13 to prevent the hinge shaft 10 from moving axially.

[0035] When the stacker-reclaimer is retrieving materials, the materials go from the bucket wheel head to the cantilever belt conveyor, through the center drop bucket, and fall into the system belt. The height of the drop roller from the system belt is mostly between 5m and 8m. Due to the large drop, it is very easy to cause a lot of dust, and the large drop increases the impact on the system belt. Therefore, the drop point here adopts a turning point arrangement, and the direct drop difference of the material can be reduced by multiple bends, thereby reducing the impact force and reducing dust. By adding the device of this application, the problem of excessive drop difference can be directly reduced, thereby reducing the impact force and reducing dust.

[0036] After the material is thrown from the cantilever belt conveyor drum, it falls onto the buffer baffle 20. Due to the existence of gravity and impact force, the present application is equipped with a counterweight 31 to play a buffering role in the material unloading process. The buffer baffle 20 rotates around the hinge shaft 10, and the material falls to the coal baffle. After the counterweight 31 plays a buffering role, due to the action of gravity, the coal baffle automatically rotates around the hinge shaft, so that the material falls into the lower system belt.

[0037] A plurality of adjustment holes 31 are provided on the counterweight arm 30. According to the amount of material and the impact force of the material, a reasonable adjustment hole 31 is selected to install the counterweight 31 to adjust the counterweight lever arm. The adjustment can also be made according to the actual working conditions on site. When the counterweight is installed in the adjustment hole 31 close to the hinge seat shaft 10, the lever arm is shorter. When the counterweight is installed in the adjustment hole 31 far away from the hinge seat shaft 10, the lever arm is longer.

[0038] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
