[0002] Bucket elevator is a continuous conveying machine that uses a series of buckets evenly fixed on an endless traction member to lift materials vertically. Bucket elevator uses a series of buckets fixed on a traction chain or belt to transport bulk materials upward in a vertical or nearly vertical direction. A backstop is required in a bucket elevator.

[0003] After searching, it was found that the check valve in the prior art, such as a bucket elevator check valve disclosed in publication number CN204124695U, has a simple structural design and is easy to adjust. When the bucket elevator belt reverses, it can ensure that the pawl clamps the ratchet wheel, hindering the reverse movement of the head wheel and preventing the bucket elevator from reversing.

[0004] The existing bucket elevator check valve adopts an integrated setting. Due to the long-term operation of the equipment, the ratchet part is severely worn and needs to be replaced as a whole. The replacement and maintenance costs are high. Therefore, we propose an improved bucket elevator check valve. Utility Model Content

[0007] Preferably, an oil storage tank is installed near the top of the front surface of the bucket elevator, an oil filling pipe is installed near the bottom of one side of the oil storage tank, an oil filling head is installed at the end of the oil filling pipe, and an oil filling pump is installed in the middle of the oil filling pipe.

[0008] Preferably, a rotating shaft is installed on the front surface of the bucket elevator at the top of the ratchet wheel, and a scraper is installed on one side of the rotating shaft.

[0009] Preferably, a limit plate is installed on the front surface of the bucket elevator on both sides close to the scraper, and a spring is installed at the gap between the limit plate and the scraper through a spring seat.

[0010] Preferably, the oil storage tank is filled with lubricating oil.

[0011] Preferably, a ratchet mechanism is installed on the front surface of the bucket elevator close to the ratchet wheel.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model achieves the effect of a split-type ratchet mechanism by arranging bolts, an inner wheel and a ratchet, so as to solve the problem that the existing bucket lift check valve adopts an integrated setting, the ratchet part is severely worn due to the long-term operation of the equipment, and needs to be replaced as a whole, and the replacement and maintenance costs are high. The convenience of replacing the ratchet mechanism is improved, and the maintenance cost of the ratchet mechanism is reduced.

[0014] 2. The utility model achieves the effect of lubricating the outer surface of the ratchet by arranging an oil storage tank, an oil filling pipe, a scraper and a spring, so as to solve the problem that the ratchet needs to be lubricated manually when in use, resulting in poor maintenance efficiency, thereby improving the lubrication effect of the ratchet.

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1-3As shown, in order to achieve the above purpose, the utility model provides the following technical solutions: an improved bucket elevator check valve, including a bucket elevator 1 and a ratchet 3, a driving shaft 9 is installed in the middle of the bucket elevator 1, an inner wheel 4 is installed on the outer surface of the driving shaft 9 through a key 2, a ratchet 3 is installed on the outer surface of the inner wheel 4, a bolt 10 is sleeved on the front side of the inner wheel 4 near the outer surface, and the end of the bolt 10 is screwed into the ratchet 3 to facilitate separation of the ratchet 3 and the inner wheel 4, an oil storage tank 8 is installed near the top on the front surface of the bucket elevator 1, an oil filling pipe 6 is installed near the bottom on one side of the oil storage tank 8, an oil filling head 5 is installed at the end of the oil filling pipe 6, and a bolt 10 is installed in the middle of the oil filling pipe 6. An oil injection pump 7 is installed, and the lubricating oil is transported to the outer surface of the ratchet 3 through the oil injection pump 7. A rotating shaft 14 is installed on the front surface of the bucket elevator 1 at the top of the ratchet 3, and a scraper 13 is installed on one side of the rotating shaft 14 to scrape the lubricating oil. A limit plate 11 is installed on the front surface of the bucket elevator 1 on both sides near the scraper 13. A spring 12 is installed at the gap between the limit plate 11 and the scraper 13 through a spring seat. The scraper 13 is squeezed by the spring 12, so as to facilitate the scraping of the lubricating oil on the surface of the ratchet 3. The oil storage tank 8 is filled with lubricating oil, and a ratchet mechanism is installed on the front surface of the bucket elevator 1 near the ratchet 3.

[0021] The working principle of an improved bucket elevator check valve based on the embodiment is: after the utility model is installed, when in use, the check effect on the bucket elevator 1 is achieved by setting the pawl and the ratchet 3, and at the same time, the lubricating oil inside the oil storage tank 8 is extracted through the oil filling pump 7, and transported to the oil filling head 5 through the oil filling pipe 6, and then transported to the outer surface of the ratchet 3 through the oil filling head 5, so as to lubricate the outer surface of the ratchet 3. When the ratchet 3 is worn, after removing the key 2, the inner wheel 4 and the ratchet 3 are removed, and then the bolt 10 is disassembled. After completion, the ratchet 3 is separated from the inner wheel 4, so as to replace the ratchet 3. At this point, the working process of this equipment is completed.
