Abstract
Description
Technical Field

[0002] Bucket elevator is a continuous conveying machine that uses a series of buckets evenly fixed on the endless traction member to lift materials vertically. Bucket elevator uses a series of buckets fixed on the traction chain or belt to transport bulk materials upward in the vertical or nearly vertical direction. After the bucket is loaded with materials, it is lifted to the top with the conveyor belt or chain, and then turned down after bypassing the top wheel. The bucket dumps the material from the discharge port into the receiving trough. Since the bucket elevator lifts different materials or feeds different amounts, the running speed of the bucket is also different, otherwise it will cause excessive return material or accumulation of materials at the bottom of the elevator, so uniform feeding should be ensured when using the bucket elevator.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example 1
[0023] like Figure 1-2 As shown, a bucket elevator comprises a bucket elevator body and a feeding device 1.
[0024] Similar to the prior art, the bucket elevator body includes a lifting device 2, a hopper 3 and a discharge port 4. The hopper 3 is evenly installed on the lifting device 2, the lifting device 2 is arranged inside the bucket elevator housing, and the discharge port 4 is arranged at the upper end of the bucket elevator.
[0025] Different from the prior art, the feeding device 1 includes a feeding hopper 5, a feeding pipe 8, a first storage bin 10 and a second storage bin 13. A feeding port is provided at the top of the feed hopper 5, and a feeding pipe 8 is provided at the outlet at the bottom. The interior of the feed hopper 8 is divided into a feeding bin at the top, a storage bin at the middle and an outlet bin at the bottom by two upper and lower horizontal partitions; the storage bin is divided into the first storage bin 10 and the second storage bin 13 by vertical partitions.
[0026] The discharge bin is connected to the feeding pipe 8, through which the material is fed to the hopper of the bucket elevator.
[0027] The first material storage bin 10 is provided with a first feed valve 11 and a first discharge valve 12. The first feed valve 11 is arranged on a transverse partition above the first material storage bin 10, connecting the first material storage bin 10 with the feed bin. The first discharge valve 12 is arranged on a transverse partition below the first material storage bin 10, connecting the first material storage bin 10 with the discharge bin.
[0028] The second material storage bin 13 is provided with a second feed valve 14 and a second discharge valve 15. The second feed valve 14 is arranged on a transverse partition above the second material storage bin 13, connecting the second material storage bin 13 with the feed bin. The second discharge valve 15 is arranged on a transverse partition below the second material storage bin 13, connecting the second material storage bin 13 with the discharge bin.
[0029] The first feed valve 11, the first discharge valve 12, the second feed valve 14 and the second discharge valve 15 are all controlled by the 2 controllers. When the machine is just started, the first feed valve 11 is first opened to allow the material to enter the first feed valve 11. When the first storage bin 10 is full of material, the first feed valve 11 is closed and the second feed valve 14 is opened. At this time, the first storage bin 10 starts to discharge material, and the second storage bin 13 starts to feed material. When the material in the first storage bin 10 is discharged and the second storage bin 13 is full of material, the second feed valve 14 and the first discharge valve 11 are closed at the same time, and the first feed valve 11 and the second discharge valve 15 are opened at the same time. At this time, the second storage bin 13 starts to discharge material and the first storage bin 10 starts to feed material. Repeating the above steps can achieve the function of continuous and uniform feeding.
[0030] The feeding device 1 further includes a rotating shaft 6, a stirring rod 7 and a rotating motor 9. The rotating shaft 6 is rotatably arranged on the inner wall of the feeding hopper 5. A plurality of stirring rods 7 are axially arranged on the outer surface of the rotating shaft 6. The rotating motor 9 is arranged on the outer wall of the feeding bin, and its output end is connected to the rotating shaft 6. The rotating motor 9 can drive the rotating shaft 6 to rotate, and the rotating shaft 6 drives the plurality of stirring rods 7 thereon to rotate together, so as to achieve a stirring effect, and the material can be kept in a loose state, thereby avoiding the material from being blocked in the feeding hopper 5.
[0031] One end of the feeding pipe 8 is communicated with the lower end of the feed hopper 5 , and the other end is connected to the bucket elevator housing and extends into the interior of the housing to feed the hopper 3 .
[0032] In this embodiment, weighing sensors are disposed in the first material storage bin 10 and the second material storage bin 13, and the weighing sensors send detected signals to the controller.
[0033] The controller output is executed, thereby controlling the operation of the first feed valve 11 , the first discharge valve 12 , the second feed valve 14 , and the second discharge valve 15 .
[0034] Specifically, the first storage bin 10 discharges material, the first feed valve 11 is closed, and the first discharge valve 12 is opened; when the weight of the material in the first storage bin 10 reaches a low set threshold value in the data transmitted to the controller by the weighing sensor, the first discharge valve 12 is closed, the first feed valve 11 is opened, the second discharge valve 15 is opened, and the second feed valve 14 is closed. When the weight of the material in the first storage bin 10 reaches a high set threshold value, the first feed valve 11 of the first storage bin 10 is closed.
[0035] In this embodiment, the priority mode of designing the discharge speed is that when the weight of the material in the first storage bin 10 reaches a low set threshold, the weight of the material in the second storage bin 13 reaches a high set threshold.
[0036] In this embodiment, two independent storage bins are used for feeding and discharging respectively to meet the requirements of continuous feeding, because when the feeding device is continuously feeding, the feeding port of the feeding device must be continuously fed, and the discharging port must be continuously fed. If the feeding port and the discharging port of the feeding device remain in a connected state, the feeding gravity will impact the discharging, resulting in uneven discharging. Therefore, in this embodiment, two storage bins are provided in the feed hopper, and their function is to prevent the feeding port from being connected to the discharging port, that is, when the first storage bin 10 is connected to the feeding port of the feed hopper 5, the second storage bin 13 is not connected to the feeding port of the feed hopper 5, but is connected to the discharging port of the feed hopper 5.
[0037] According to the above embodiments, the present invention can be well implemented. It is worth noting that, based on the above structural design, in order to solve the same technical problem, even if some insubstantial changes or modifications are made to the present invention, the essence of the technical solution adopted is still the same as that of the present invention, so it should also be within the protection scope of the present invention.
