Description

Technical Field

[0001] The utility model relates to the technical field of bucket wheel stacker reclaimers, in particular to a bucket wheel material blocking device of a bucket wheel stacker reclaimer. Background Art

[0002] Bucket wheel stacker reclaimer is a large-scale bulk material loading and unloading equipment with high efficiency and continuous operation. It is mainly used in coal and ore storage yards in industries such as power, metallurgy, coal, building materials and chemical industry. Bucket wheel stacker reclaimer is mainly composed of bucket wheel mechanism, cantilever belt conveyor, boom, balance beam, slewing platform, door seat, tail car, slewing mechanism, pitching mechanism and walking mechanism. The bucket wheel mechanism is installed at the front end of the boom to dig materials.

[0003] Bucket wheel stacker reclaimer reclaiming operation includes two operation modes: rotary layered reclaiming and fixed-point slope reclaiming. Rotary layered reclaiming is divided into two operation modes: segmented and non-segmented according to the height of the pile. The disadvantages of rotary layered segmented reclaiming and fixed-point slope reclaiming are: when digging the lower layer of materials, it is easy to cause the pile above to collapse, causing the bucket wheel and boom of the equipment to overload. The rotary layered non-segmented reclaiming method can avoid the collapse of the pile, but it is only applicable to lower and shorter piles, and has certain limitations.

[0004] When the prior art excavates a material with a slope at a fixed point on the bottom, it is easy to cause the material above to collapse, which may cause the bucket wheel and boom of the equipment to be overloaded. Utility Model Content

[0005] In order to solve the deficiencies mentioned in the above background technology, the purpose of the utility model is to provide a bucket wheel material blocking device for a bucket wheel stacker and reclaimer. During the excavation process, the vibrator is started to make the oscillation component vibrate, which helps the material under the baffle to slide to the hollowed area of ​​the bucket wheel to avoid accumulation. The baffle is always on the material under its own gravity, and will change with the angle of the material, always maintaining the blocking effect on the material above, effectively preventing landslides and ensuring the safety of the bucket wheel and the boom. It has a simple structure and is easy to operate, which can greatly improve work efficiency and reduce operating costs.

An excavation opening 7 is provided on the baffle 5, and the excavation opening 7 is designed to ensure that the bucket wheel can pass smoothly when excavating materials without any obstacles.

[0026] A guide plate 8 is arranged on one side of the baffle plate 5 away from the slide bar 4. The guide plate 8 is arranged vertically. There are multiple guide plates 8 arranged and distributed in an array under the baffle plate 5. The guide plate 8 guides the sliding material to the position of the bucket wheel.

[0027] A plurality of through holes 9 are provided on the sleeve rod 3 and the slide rod 4, and fixing bolts 10 adapted to the through holes 9 are provided on the sleeve rod 3. According to the height of the pile, the sliding position of the slide rod 4 in the sleeve rod 3 is adjusted so that the baffle 5 is at a suitable height.

[0031] Working principle:

[0032] Before the bucket wheel stacker and reclaimer starts working, first install the extension frame to the truss through the mounting parts. Specifically, place the two clamps on the upper and lower sides of the truss end respectively, then pass the screws through the screw holes and tighten the screw sleeves to tightly fix the two clamps to the truss ends. Next, adjust the sliding position of the slide bar in the sleeve bar according to the height of the material pile so that the baffle is at an appropriate height. Specifically, first pull out the fixing bolts, then stretch the slide bar until the baffle contacts the material and begins to bear the weight of the baffle, then insert the fixing bolts into the corresponding through-holes to limit the sleeve bar and the slide bar so that they no longer deviate. Since the outer side surface of the slide bar fits with the inner side surface of the sleeve bar, the sliding between the sleeve bar and the slide bar is stable and no shaking occurs.

[0033] During the excavation process, the vibrator is activated to vibrate the oscillating assembly, which helps the material under the baffle to slide down to the area hollowed out by the bucket wheel to avoid accumulation. At the same time, the guide plate guides the sliding material to the location of the bucket wheel.

[0034] During the entire work process, the baffle is always on the material under the action of its own gravity, and will change with the angle of the material, always maintaining the blocking effect on the material above, effectively preventing landslides and ensuring the safety of the bucket wheel and boom. At the same time, its simple structure and easy operation can greatly improve work efficiency and reduce operating costs. At this time, the first limiting rod and the second limiting rod will limit the maximum rotation angle of the baffle to ensure safe operation.
