Description

Technical Field

[0001] The utility model relates to the technical field of rice conveying devices, and particularly relates to a rice conveying device. Background Art

[0002] Rice refers to the unhulled seeds. Botanically, it belongs to the common cultivated rice subspecies in the genus Oryza of the Gramineae family. Humans have identified 22 types of rice in total, but the only one used for bulk trade is the common type. The external structure of rice grains mainly consists of two parts: the glume (husk) and the caryopsis (brown rice).

[0003] According to the patent document: CN210504391U, a disclosed delay speed-regulating screw-type rice conveying device belongs to the field of mechanical technology. It solves the problem of uneven material falling of the existing conveying device. This delay speed-regulating screw-type rice conveying device includes a barrel-shaped outer shell, a metering screw rotatably arranged horizontally in the outer shell, and a motor arranged outside the outer shell. The main shaft of the motor extends into the outer shell and is connected to the metering screw. Feeding ports and discharging ports are respectively arranged on the top wall and the bottom wall of the outer shell. A cylinder with both ends open is vertically arranged below the outer shell, and the cylinder is fixedly connected to the outer shell. The outer shell and the cylinder are communicated through the discharging port. A cover plate is arranged directly below the cylinder, and the cover plate is hinged to the cylinder through a columnar rotating member. A torsion spring is arranged on the rotating member to make the cover plate have a tendency to rotate around the axis of the rotating member and close the lower port of the cylinder. This delay speed-regulating screw-type rice conveying device has relatively uniform material falling.

[0004] After rice processing is completed, it is generally stored in a granary. However, when the rice needs to be taken out of the granary for further processing, there is a large amount of rice in the granary, and the rice is tightly piled up. A large amount of dust or small gravel may be mixed in the rice. When taking out the rice, the rice and small gravel are easily conveyed out together, which will affect the quality of the rice. In addition, when conveying the rice, generally workers use a trolley for conveying. However, when loading the trolley with rice, it is impossible to control the flow rate of the rice conveyed into the trolley, which easily leads to an excessive amount of rice being conveyed at one time, causing the trolley to be unable to carry too much rice and tip over. This will cause losses and waste of rice and also increase the labor intensity of workers. Content of the Utility Model

[0028] When rice needs to be conveyed, first pour the rice into the main body 11 of the screening bin through the feeding hopper 12. The rice will fall on the filter screen plate 213. Since the filter screen 214 on the filter screen plate 213 can screen out the impurities in the rice, leaving the impurities on the filter screen plate 213, while the clean rice falls into the conveying bin 3 through the filter screen 214.

The shaking bin 33 includes a shaking bin outer shell 331. On the left and right sides of the inner wall of the shaking bin outer shell 331, shaking bin chutes 332 are respectively opened. At the left and right sides of the bottom of the inner wall of the shaking bin outer shell 331, shaking motor placement blocks 335 are respectively fixedly connected. Inside the two shaking motor placement blocks 335, shaking motors 336 are fixedly connected. The output ends of the two shaking motors 336 are both fixedly connected with second rotating shafts 337. On the front sides of the two second rotating shafts 337, second rotating rods 338 are fixedly connected. On the outer walls of the two second rotating rods 338, oval sliding shafts 339 are slidably connected. At the tops of the two oval sliding shafts 339, push-pull rods 3310 are fixedly connected. The tops of the two push-pull rods 3310 both penetrate to the tops of the shaking motor placement blocks 335 and springs are sleeved on their outer walls. The tops of the two push-pull rods 3310 are both fixedly connected with shaking blocks 334. The opposite surfaces of the two shaking blocks 334 are both slidably connected to the inner walls of the shaking bin chutes 332 and multiple shaking springs 333 are fixedly connected to their bottoms. The bottoms of the two groups of shaking springs 333 are both fixedly connected to the bottom of the inner wall of the shaking bin chutes 332. At the rear side of the shaking bin outer shell 331, two spring telescopic rods 3311 are fixedly connected. The conveying inclined plate 34 includes a conveying inclined plate outer shell 341. On the left and right sides of the front side of the conveying inclined plate outer shell 341, they are respectively fixedly connected to the opposite sides of the two shaking blocks 334. At the bottom of the rear side of the conveying inclined plate outer shell 341, it is fixedly connected to the tops of the two spring telescopic rods 3311. On the left and right sides of the conveying inclined plate outer shell 341, screw rod motor placement blocks 342 are respectively fixedly connected. At the tops of the two screw rod motor placement blocks 342, screw rod motors 343 are fixedly connected. The output ends of the two screw rod motors 343 are both fixedly connected with screw rod transmission shafts 344.

The outer walls of the left and right sides of the baffle 349 are both slidably connected to the inner walls of the two inclined plate sliding rods 348;

[0030] After the preliminary screening of paddy through the filter plate 213 and the filter screen 214, it enters the conveying bin 3 and then falls on the conveying inclined plate 34. At this time, the shaking motor 336 in the shaking bin 33 starts, driving the second rotating shaft 337 and the second rotating rod 338 to rotate, and then driving the elliptical sliding shaft 339 and the push-pull rod 3310 to move up and down. Since the top of the push-pull rod 3310 is fixedly connected with the shaking block 334, the shaking block 334 will also slide up and down in the shaking bin chute 332, and at the same time compress or stretch the shaking spring 333 to produce a shaking effect. The shaking of the shaking block 334 will drive the conveying inclined plate housing 341 and the conveying inclined plate 34 to shake, so as to shake and loosen the paddy on the conveying inclined plate 34, preventing the paddy from accumulating and blocking during the conveying process;

[0031] At the same time, the lead screw motor 343 starts, driving the lead screw transmission shaft 344 and the second lead screw transmission shaft 345 to rotate, and then driving the lead screw transmission track 346 and the lead screw 347 to rotate. Since the bottom of the lead screw 347 is movably connected to the inner bottom of the inclined plate slide rod 348, and the outer wall of the lead screw 347 is threadedly connected with the baffle 349, the rotation of the lead screw 347 will drive the baffle 349 to move up and down on the inner wall of the inclined plate slide rod 348, so as to control the conveying speed and conveying volume of the paddy on the conveying inclined plate 34. By adjusting the rotation speed and direction of the lead screw motor 343, the position and moving speed of the baffle 349 can be conveniently controlled to achieve the precise conveying of paddy;

[0032] After shaking and conveying, the paddy will enter the next process, such as further processing or packaging. During the whole conveying process, the start and stop of the shaking motor 336 and the lead screw motor 343 can be conveniently controlled through the control board 2, so as to control the shaking effect and conveying speed of the paddy, ensuring the smooth conveying and processing quality of the paddy.

[0033] Working principle: When using this device, when it is necessary to convey paddy, first pour the paddy into the main body 11 of the screening bin through the feeding hopper 12. The paddy will fall on the filter screen plate 213. Since the filter screen 214 on the filter screen plate 213 can screen out the impurities in the paddy, the impurities are left on the filter screen plate 213, while the clean paddy falls into the conveying bin 3 through the filter screen 214. Subsequently, the motor 23 is started to drive the transmission shaft 24 to rotate, and then drive the crawler 25 to rotate, so that the second transmission shaft 26 and the rotating rod 27 rotate simultaneously. The rotation of the rotating rod 27 drives the circular rotating shaft 29 and the rotating rod 210 to rotate. Since the outer wall of the rotating rod 210 is movably connected to the inner wall of the elliptical rotating groove 212 opened at the rear side of the filter screen plate shaking block 211, the filter screen plate shaking block 211 will shake left and right under the drive of the rotating rod 210, thereby driving the filter screen plate 213 and the filter screen 214 to shake, shaking off the impurities remaining on the filter screen plate 213 and preventing the impurities from blocking the filter screen 214. The paddy that has been screened and shaken will enter the conveying bin 3, and then be conveyed to the next process through the conveying device in the conveying bin 3. During the whole process, the start and stop of the motor 23 can be conveniently controlled through the control board 2, so as to control the conveying speed and screening effect of the paddy. At the same time, the rubber transparent plate 13 on the front side of the main body 11 of the screening bin can conveniently observe the blockage condition of the filter screen 214 and clean it in time;

[0034] After the preliminary screening of paddy through the filter screen plate 213 and the filter screen 214, it enters the conveying bin 3 and then falls on the conveying inclined plate 34. At this time, the shaking motor 336 in the shaking bin 33 starts, driving the second rotating shaft 337 and the second rotating rod 338 to rotate, and then driving the elliptical sliding shaft 339 and the push-pull rod 3310 to move up and down. Since the top of the push-pull rod 3310 is fixedly connected with the shaking block 334, the shaking block 334 will also slide up and down in the shaking bin chute 332, while compressing or stretching the shaking spring 333 to produce a shaking effect. The shaking of the shaking block 334 will drive the conveying inclined plate housing 341 and the conveying inclined plate 34 to shake, so as to shake and loosen the paddy on the conveying inclined plate 34, prevent the paddy from accumulating and blocking during the conveying process. At the same time, the lead screw motor 343 starts, driving the lead screw transmission shaft 344 and the second lead screw transmission shaft 345 to rotate, and then driving the lead screw transmission track 346 and the lead screw 347 to rotate. Since the bottom of the lead screw 347 is movably connected to the inner bottom of the inclined plate sliding rod 348 and the outer wall of the lead screw 347 is threadedly connected with the baffle 349, the rotation of the lead screw 347 will drive the baffle 349 to move up and down on the inner wall of the inclined plate sliding rod 348, so as to control the conveying speed and conveying volume of the paddy on the conveying inclined plate 34. By adjusting the rotation speed and direction of the lead screw motor 343, the position and moving speed of the baffle 349 can be conveniently controlled to achieve the precise conveying of paddy. After shaking and conveying, the paddy will enter the next process, such as further processing or packaging. During the whole conveying process, through the control board 2, the start and stop of the shaking motor 336 and the lead screw motor 343 can be conveniently controlled, so as to control the shaking effect and conveying speed of the paddy, and ensure the smooth conveying and processing quality of the paddy.
