Description

Technical Field

[0001] The invention belongs to the technical field of conveying equipment, in particular to a bottom-cleaning and flapping device for an unpowered automatic bucket elevator. Background Art

[0002] In the prior art, it is difficult to avoid material dropping during the operation of the bucket elevator due to feeding and unloading. Severe material dropping often results in excessive bottom aggregate, which affects the bucket wear of the bucket elevator and even causes component damage.

[0003] To solve this problem, there is currently a method of adding a short belt conveyor and a scraper conveyor at the bottom of the bucket elevator to remove the bottom material. Although this can achieve the effect of removing the bottom material, it will also cause many problems.

[0004] 1. The bucket elevator is designed to prevent material dropping, but it cannot completely avoid material dropping, so the amount of material dropping will not be very serious and the amount of material dropping is very small. A short belt conveyor and a scraper are added to the bottom of the bucket elevator to remove the bottom dropped materials. If the belt conveyor and the scraper work together with the bucket elevator, they need to run for a long time, which is not only inefficient, but also wastes energy.

[0005] 2. Use belt conveyors and scrapers to clean the bottom material. Since the material conveying outlet is always connected to the outside world, the dust inside the bucket elevator is easy to leak, affecting the working environment. Therefore, many companies that adopt this method also need to add sealing covers and dust collection devices, which have complex structures and high costs.

[0006] 3. Adding a belt conveyor or scraper conveyor at the bottom of the bucket elevator means adding maintenance and overhaul equipment, which not only increases the maintenance cost, but also adds a lot of inconvenience and difficulty to the monitoring, maintenance and overhaul of the equipment because the bottom of many bucket elevators are set in the pit. Summary of the invention

[0007] The purpose of the present invention is to provide a non-powered automatic bucket elevator bottom cleaning flap device in view of the above-mentioned shortcomings. The device requires no power, no monitoring, is simple to repair and maintain, has a simple structure, is low in cost, and can automatically remove the bottom material inside without manual cleaning.

[0008] The technical solution of the present invention is: a non-powered automatic bucket elevator bottom cleaning flap device, which is characterized by comprising a material receiving cross-shaped flap arranged at the lower part of the bucket elevator lower rotating device, and a rotating shaft arranged in the middle; the horizontal flap end of the cross-shaped flap is in contact with the side wall of the bucket elevator with a small gap; and a material receiving plate and a left discharge port and a right discharge port are designed on the side wall of the bucket elevator corresponding to the lower side of the cross-shaped flap.

[0009] The above scheme also includes:

[0010] Material receiving inclined plates are welded on both sides of the upper vertical plate of the cross-shaped flap.

[0011] The lower part of the lower flap of the cross-shaped flap is welded with a counterweight round steel which is conducive to the resetting of the cross-shaped flap.

[0012] The advantages of the present invention are: 1. It has a simple structure, and is easy to manufacture, install, maintain and overhaul, and has low cost. 2. The device adopts a non-powered design and has no operating cost. 3. The device adopts automatic flipping and cleaning, which does not require long-term monitoring and saves labor costs. 4. The use of this device can achieve the advantages of no material stored at the bottom of the bucket elevator and high protection. 5. When this device is used, when the cross-shaped flap is balanced, the dust leakage inside the sealing machine can be achieved. At the same time, a canvas dust curtain is added to the discharge port, which can greatly reduce the dust leakage. The structure is simple and the effect is ideal.

[0013] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the equilibrium state structure of the present invention.

[0015] Figure 2 It is a schematic structural diagram of the left side unloading state of the present invention.

[0016] Figure 3 It is a schematic structural diagram of the right side unloading state of the present invention. DETAILED DESCRIPTION

[0017] See also Figure 1-3 The names of the parts are as follows: cross-shaped flap 1, rotating shaft 2, material receiving inclined plate 3, bucket elevator inlet 4, bucket elevator side wall 5, counterweight round steel 6, material receiving plate 7, left discharge port 8, right discharge port 9, material dropping at the feed port 10, and material dropping at the discharge port 11.

[0018] See also Figure 1The bottom-clearing flap device of the unpowered automatic bucket elevator is a cross-shaped flap 1 for receiving materials arranged at the lower part of the lower rotating device of the bucket elevator. The structure of the cross-shaped flap 1 is cross-shaped, and a rotating shaft 2 is arranged in the middle. Rolling bearing seats are installed at both ends of the rotating shaft 2, so that the cross-shaped flap 1 can realize axial rotation. The material-receiving inclined plates 3 are welded on both sides of the upper vertical plate of the cross-shaped flap 1 to prevent the material from piling up toward the center of the rotating shaft 2 and affecting the flipping. The horizontal flap end of the cross-shaped flap is kept in contact with the side wall 5 of the bucket elevator as close as possible, and the cross-shaped flap 1 plays a role in sealing the dust from spilling when balanced. The lower part of the lower flap of the cross-shaped flap is welded with a counterweight round steel 6, which is used to reset the cross-shaped flap 1 by gravity after the cross-shaped flap 1 is unloaded. The lower side of the cross-shaped flap is designed with a receiving plate 7 and a left discharge port 8 and a right discharge port 9, which are used to limit the angle of the cross-shaped flap 1 and the function of receiving and discharging materials. At the same time, a canvas dust curtain (not shown) is provided at the discharge port to reduce dust spillage during unloading. The cross-shaped flap 1 is made of wear-resistant material (61Mn), and the rotating shaft 2 is made of 45 # .

[0019] Working principle: When material drops from the bucket elevator inlet 4, the material drops into the left area of ​​the cross-shaped flap 1. As the accumulated weight of the material exceeds the weight of the accumulated material on the right or the weight of the bottom counterweight round steel 6, the cross-shaped flap 1 will flip to the left and discharge the material through the lower left discharge port 8 of the bucket elevator (the cross-shaped flap 1 will be limited by the lower receiving plate 7 after tilting). When material drops from the bucket elevator discharge port, the principle is the same as on the left.

[0020] The above description is only a specific implementation mode of the present invention, and various examples do not constitute a limitation on the essential content of the present invention.
