Abstract
Description
Technical Field
[0001] This invention relates to the technical field of bucket elevators, and in particular to the technical field of a non-accumulating bucket elevator tail section. Background Technology
[0002] like Figure 4 As shown, the elevator mainly consists of a head section (A), an intermediate section (B), a tail section (C), and running parts inside the casing (i.e., chain buckets). Material enters through the feed inlet C1 at the tail section. Material enters the bucket, is then lifted to head A, and finally discharged from outlet A1 at head A. During this process, a small amount of material may not enter the bucket and instead fall directly to the bottom of the elevator. Over time, this fallen material (i.e., loose material) will gradually accumulate at the bottom of the elevator. When the accumulated thickness enters the operating range of the bucket opening, the bucket will dig out the overlapping part, lifting the loose material from the overlapping part. When the loose material accumulates to a certain thickness on the bottom plate, the running bucket will dig out the loose material at the tail end, digging it into the bucket. On the one hand, the digging of the bucket increases the wear of the bucket, greatly shortening its service life; on the other hand, the digging and friction increase the resistance of the bucket during operation, which will have a certain harmful impact on the elevator chain, transmission, and drive. Summary of the Invention
[0003] The purpose of this invention is to solve the problems in the prior art and propose a non-accumulating bucket elevator tail section, which can improve the service life of the buckets, avoid causing certain harmful impacts to the bucket elevator, and eliminate the need for regular shutdown for manual cleaning.
[0004] To achieve the above objectives, the present invention proposes a non-accumulating bucket elevator tail section, comprising a tail casing, an accumulating hopper, a material conveyor, and a vibrating motor. The bottom of the tail casing is provided with an accumulating hopper communicating with it. The accumulating hopper includes a hopper body and a discharge pipe communicating with the lower end of the hopper body. The discharge pipe is inclined and a vibrating motor is provided on the discharge pipe. The lower end of the discharge pipe is connected to the inlet of the material conveyor. The tail casing is provided with an inlet II located below the inlet I. The outlet of the material conveyor is connected to the inlet II.
[0005] Preferably, the material conveyor is a tubular screw conveyor.
[0006] Preferably, a material level sensor is provided at the upper part of the hopper and the lower end of the discharge pipe.
[0007] Preferably, the internal space of the discharge pipe gradually increases from low to high.
[0008] Preferably, the hopper is equipped with a dispersing mechanism for dispersing the material inside the hopper.
[0009] Preferably, the dispersing mechanism includes an inclined rod, a vertical rod, a plurality of dispersing rods I, and a swinging drive mechanism. The inclined rod is located inside the discharge pipe, and the discharge pipe is provided with a support shaft that is movably connected to the lower end of the inclined rod. The upper end of the inclined rod is provided with a vertical rod located inside the hopper, and the hopper is provided with a swinging drive mechanism connected to the vertical rod. Dispersing rods I are provided on both the inclined rod and the vertical rod.
[0010] Preferably, the swing drive mechanism includes a swing rod, a drive cylinder, a sleeve, a slide groove, a sliding body, and a rubber dust cover. The sleeve is fixedly installed on the rear side wall of the bucket body. The swing rod is rotatably installed inside the sleeve. The front end of the sleeve is provided with a slide groove facing the vertical rod. The sliding body is slidably fitted inside the slide groove. The sliding body is rotatably connected to the upper end of the vertical rod. The drive cylinder is located on the outside of the bucket body. The piston rod of the drive cylinder is hinged to the rear end of the swing rod. A rubber dust cover is provided between the rear end of the sleeve and the swing rod.
[0011] The inclined rod is provided with two rows of dispersion rods I, and a dispersion rod II is provided between two adjacent dispersion rods I. The vertical rod is provided with two rows of dispersion rods I, and a dispersion rod III is provided between two adjacent dispersion rods I.
[0012] The beneficial effects of this invention are as follows: This invention collects spilled materials through a bucket and sends them to a material conveyor through a discharge pipe. The material is then lifted by the material conveyor and enters inlet II, and then outputs from inlet II into the corresponding lifting bucket. The vibration of the vibrating motor improves the smoothness of material discharge through the discharge pipe. Compared with the prior art, this invention can improve the service life of the bucket, avoid causing certain harmful impacts to the bucket elevator, and eliminate the need for regular shutdown for manual cleaning.
[0013] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. Attached Figure Description

Detailed Implementation
[0016] See Figure 1 , Figure 2 and Figure 3 The present invention discloses a non-accumulating bucket elevator tail section, comprising a tail casing 1, a accumulating hopper 2, a material conveyor 3, and a vibrating motor 4. The bottom of the tail casing 1 is provided with the accumulating hopper 2 connected thereto. The accumulating hopper 2 includes a hopper body 21 and a discharge pipe 22 connected to the lower end of the hopper body 21. The discharge pipe 22 is inclined and is equipped with the vibrating motor 4. The lower end of the discharge pipe 22 is connected to the input port of the material conveyor 3. The tail casing 1 is provided with an input port II7 located below the input port I6. The output port of the material conveyor 3 is connected to the input port II7.
[0017] The material conveyor 3 is a tubular screw conveyor.
[0018] Material level sensors 5 are provided on the upper part of the hopper 21 and the lower end of the discharge pipe 22.
[0019] The internal space of the discharge pipe 22 gradually increases from low to high.
[0020] The hopper 2 is equipped with a dispersing mechanism 8 for dispersing the material inside the hopper 2.
[0021] The dispersing mechanism 8 includes an inclined rod 81, a vertical rod 82, a plurality of dispersing rods I83, and a swing drive mechanism 84. The inclined rod 81 is located inside the discharge pipe 22. The discharge pipe 22 is provided with a support shaft 85 that is movably connected to the lower end of the inclined rod 81. The upper end of the inclined rod 81 is provided with a vertical rod 82 located inside the hopper 21. The hopper 21 is provided with a swing drive mechanism 84 that is connected to the vertical rod 82. Dispersing rods I83 are provided on both the inclined rod 81 and the vertical rod 82.
[0022] The swing drive mechanism 84 includes a swing rod 841, a drive cylinder 842, a sleeve 843, a groove 844, a sliding body 845, and a rubber dust cover 846. The sleeve 843 is fixedly installed on the rear side wall of the bucket body 21. The swing rod 841 is rotatably installed inside the sleeve 843. The front end of the sleeve 843 is provided with a groove 844 facing the vertical rod 82. The sliding body 845 is slidably fitted inside the groove 844. The sliding body 845 is rotatably connected to the upper end of the vertical rod 82. The drive cylinder 842 is located on the outside of the bucket body 21. The piston rod of the drive cylinder 842 is hinged to the rear end of the swing rod 841. A rubber dust cover 846 is provided between the rear end of the sleeve 843 and the swing rod 841.
[0023] The inclined rod 81 is provided with two rows of dispersion rods I83, and a dispersion rod II86 is provided between two adjacent dispersion rods I83. The vertical rod 82 is provided with two rows of dispersion rods I83, and a dispersion rod III87 is provided between two adjacent dispersion rods I83.
[0024] Working process of this invention: In the operation of the non-accumulating bucket elevator of the present invention, the falling material falls into the accumulation hopper 2. When the material level sensor on the bucket body 21 detects that the material in the accumulation hopper 2 has reached a certain amount, the material conveyor 3, the drive cylinder 842 and the vibration motor 4 are started. The material in the accumulation hopper 2 enters the material conveyor 3, and is then lifted by the material conveyor 3 and enters the feed inlet II7. Then it is output from the feed inlet II7 and falls into the corresponding lifting hopper.
[0025] The drive cylinder 842 extends and retracts alternately, driving the swing rod 841 to swing. The swing rod 841 drives the vertical rod 82 to swing through the cooperation of the slide groove 844 and the sliding body 845. The vertical rod 82 drives the inclined rod 81 to swing. The vertical rod 82 and the inclined rod 81 drive the dispersing rod I83 on them to disperse the material, thereby facilitating material discharge.
[0026] When the material level sensor 5 at the lower end of the discharge pipe 22 detects that the material in the hopper 2 is below a certain amount, the material conveyor 3, the drive cylinder 842 and the vibration motor 4 stop working.
[0027] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
