When the grain is circularly dried, the bucket elevator 200 conveys the grain upwards and then enters the grain dryer 100 along the discharging pipeline 300, the grain is dried by hot air in the grain dryer 100 and then gathered in the collecting hopper at the lower end, and then the grain is discharged into the lower end of the bucket elevator 200 through the discharging channel 400 to be circularly lifted and dried.
The bucket elevator 200 of this embodiment 1 is an improved design based on the prior art. Referring to fig. 2 and 3, the main body of the apparatus includes a vertically disposed feed housing 201, an upper hopper 202 is disposed at a lower end of the feed housing 201, and the upper hopper 202 is disposed at the other side surface connected to the discharge passage 400. An end shield 203 is provided at the upper end of the feeder housing 201. One belt conveying roller 204 is disposed inside the lower end of the feeder housing 201 and in the end cover 203, respectively, and the two belt conveying rollers 204 are on the same vertical line. A conveyor belt 205 is provided between the two belt conveyor rollers 204, a plurality of buckets 206 are connected to the conveyor belt 205 at equal intervals, and the bucket 206 on the side close to the upper hopper 202 is designed to have an opening facing upward and the bucket on the side close to the discharge path 400 is designed to have an opening facing downward. In addition, a lifting motor 207 is arranged on the outer side surface of the end cover 203, and an output shaft of the lifting motor 207 extends into the end cover 203 and is connected with the end surface of the belt conveying roller 204. The conveyor belt 204 is driven by the lifting motor 207 to rotate clockwise in the feeding housing 201, so that the grain can be dug up by the digging hopper 206 on the conveyor belt 205 when entering the bottom end of the discharge passage 400 from the discharge passage 400 or the upper hopper 202 and then conveyed upward along with the conveyor belt 204. When the bucket is turned over as the conveyor belt 204 moves to the top of the end shield 203, the grain in the bucket 206 can be thrown down.
Referring to fig. 3, a discharging opening 2031 is formed at a lower end of the end shield 203 near the grain dryer 100, wherein a top end of the discharging pipe 300 is connected to the discharging opening 2031, so that the grain can be thrown down when the grain in the hopper 206 is turned over, and then enter the discharging pipe 300 through the discharging opening 2031. Meanwhile, the side surface of the end cover 203 close to the dryer 100 is provided with a dust suction port, and the outer end of the dust suction port is connected with a dust suction trapezoidal cover 500.
Referring to fig. 4 and 5, a plurality of strip-shaped openings 501 are formed at intervals up and down on the end surface of the trapezoid dust collection cover 500 connected with the dust collection opening, and an obliquely arranged material sliding plate 502 is connected to the inner wall of the lower end of each strip-shaped opening 501, and the oblique angle of the material sliding plate 502 can be set within the range of 40-45 degrees during specific setting, wherein the oblique angle is set to be 42 degrees, which is optimal. Finally, a dust suction pipe mounting opening is formed in the top wall of the dust suction trapezoidal cover 500, a negative pressure dust suction pipe 503 is connected to the dust suction pipe mounting opening, and the negative pressure dust suction pipe 503 is sequentially connected with a negative pressure fan, a cloth belt dust collector or a cyclone dust collector.
Due to the design of the dust collection trapezoidal cover 500, when the digging hopper 206 on the conveying belt 205 is turned over to throw off grain grains, dust, grass dust and the like in the grain grains can be adsorbed under the action of negative pressure inside the dust collection trapezoidal cover 500, then the grain grains enter the cloth belt dust collector or the cyclone dust collector along the negative pressure dust collection pipe 503 to be subjected to dust collection, and finally filtered air is discharged. Meanwhile, due to the design of the material sliding plate 502 and the strip-shaped opening 501, when the grain is sucked into the dust suction trapezoidal cover 500 in the negative pressure dust suction process, the grain slides down from the strip-shaped opening 501 along the material sliding plate 502 due to the action of the material sliding plate 502, and finally falls into the feed opening 2031.
Example 2
Embodiment 2 discloses an improved design for adjusting negative pressure dust collection air quantity of a dust collection trapezoidal cover based on embodiment 1, which is the same as embodiment 1 and will not be described again, and the difference is that:
in the embodiment 2, an air volume adjusting assembly is further arranged at the installation opening of the dust suction pipe of the dust suction trapezoidal cover 500 or on the negative pressure dust suction pipe 503.
The first design is to directly arrange an air volume adjusting valve (not shown) at the connection between the negative pressure dust suction pipe 503 and the dust suction trapezoid cover 500.
The second design scheme is that a movable baffle 504 is attached to the top wall of the dust collection trapezoidal cover 500, a support plate 505 is welded on the outer side face of the dust collection trapezoidal cover 500, a pushing device 506 is fixedly arranged on the support plate 505, the pushing device 506 can be an air cylinder, a hydraulic cylinder or an electric push rod, a socket capable of extending out the movable baffle 504 is formed in the side face of the dust collection trapezoidal cover 500, and the movable baffle 504 is directly connected with the movable end of the pushing device 506 after extending out of the socket.
The design of above-mentioned two kinds of air regulation subassemblies can be through the size of adjusting the negative pressure dust absorption amount of wind to be applicable to the negative pressure dust removal of different grain cereal, make its application scope wider.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
