Description

Technical Field

[0001] The invention relates to the technical field of conveyors, in particular to a small primary agricultural product lifting conveyor. Background Art

[0002] During the processing of rice, a bucket elevator is needed to transport the rice. At present, the bucket elevators on the market usually include an outer shell and a hopper distributed inside the outer shell. A conveyor belt is distributed inside the outer shell. The hopper inside the outer shell is rotatably connected to the conveyor belt. When the transmission motor drives the conveyor belt to move, the conveyor belt can drive the hopper to move inside the outer shell, thereby realizing the hopper-driven rice lifting and transportation. This type of bucket elevator can indeed achieve a good transportation effect on rice when it is actually used, but it still has the following shortcomings in actual use:

[0003] 1. When the existing bucket elevator is manufactured, there is a gap between the bottom point of the bucket and the bottom of the elevator shell. Although it can avoid large friction between the outer wall of the bucket and the inner wall of the elevator, it will also cause rice to remain inside the elevator, thereby reducing the transportation effect of the bucket elevator on rice.

[0004] 2. When the existing bucket elevator transports rice, the rice is usually discharged from the discharge end of the elevator in the form of throwing. Although this method can achieve a good discharge effect on the rice, it will also cause the rice of poor quality to be discharged from the discharge end of the elevator, which is not convenient for subsequent staff to process the rice;

[0005] For this purpose, we propose a small primary agricultural product lifting conveyor. Summary of the invention

[0006] A technical problem to be solved by the present application is that during the production of the existing bucket elevator, rice will remain inside the elevator and poor quality rice will be discharged from the discharge end of the elevator.

[0007] In order to solve the above technical problems, the embodiment of the present application provides a small primary agricultural product lifting conveyor, including a shell structure and a transmission structure connected to the shell structure, and also includes:

[0008] A conveyor belt is distributed inside the shell structure, and rotating parts are inserted into the upper and lower parts of the conveyor belt. The rotating part on the upper part of the conveyor belt is fixedly connected to the output end of the transmission structure. The outer wall of the conveyor belt is fixedly connected to a limit hinge. The end of the limit hinge away from the conveyor belt is fixedly connected to a hopper. The limit hinge is used to limit and flip the hopper connected to the conveyor belt.

[0009] The lower part of the shell structure is fixedly connected with a feed end and an air intake structure, the feed end includes a feed pipe fixedly connected to the shell structure and a guide groove distributed on the shell structure and located below the feed pipe, and also includes an air guide portion distributed at the lower part of the shell structure, when the air intake structure blows external air to the inside of the air guide portion, the rice inside the air guide portion can enter the inside of the hopper under the guidance of the guide groove;

[0010] An exhaust structure is fixedly connected to the top of the shell structure, and the exhaust structure includes a first discharge pipe fixedly connected to the shell structure, and the first discharge pipe is used to discharge qualified rice to the outside. A connecting ring is fixedly connected to a portion of the shell structure near the first discharge pipe, and a second discharge pipe is fixedly connected to a portion of the connecting ring near the first discharge pipe, and the connecting ring is used to drain unqualified rice to the inside of the second discharge pipe.

[0011] In some embodiments, the angle at which the limit hinge drives the hopper to flip is between zero and two hundred and twenty-five degrees, the lower portion of the shell structure is fixedly connected to a support structure, and the first discharge pipe and the second discharge pipe are arranged side by side.

[0012] In some embodiments, the air intake structure includes an air intake pipe fixedly connected to the lower portion of the shell structure, a splitter is fixedly connected to the interior of the air intake pipe, and a guide end is fixedly connected to a portion of the splitter close to the air guide portion.

[0013] In some embodiments, the partition sheet can divide the inner cavity of the air intake pipe into a lower air intake cavity and an upper air intake cavity, the lower air intake cavity can guide external air to the air guide portion, and the guide end can guide the air inside the upper air intake cavity upward.

[0014] In some embodiments, the exhaust structure further includes a connecting bracket fixedly connected between the shell structure and the connecting ring, the connecting bracket is connected to a drainage structure, the drainage structure includes a connecting column, and the connecting column is fixedly connected to the output end of the transmission structure.

[0015] In some embodiments, the end of the connecting column away from the transmission structure is fixedly connected to a transmission column, a filter cover is sleeved on the transmission column, the filter cover is fixedly connected to the connecting ring, and an air guide sheet is provided on the filter cover.

[0016] In some embodiments, the outer wall of the transmission column is fixedly connected with conveying blades and scraping rods at equal intervals, the scraping rod is fixedly connected with a storage groove, the interior of the storage groove is fixedly connected with an adhesive plate, the conveying blades are distributed inside the connecting ring, and the scraping rod abuts against the inner wall of the filter cover.

[0017] In some embodiments, the end of the connecting ring facing away from the shell structure is fixedly connected to the exhaust shell, and the inner wall of the exhaust shell near the transmission column is fixedly connected to a support frame, and the support frame is rotatably connected to the transmission column.

[0018] In some embodiments, exhaust blades are distributed inside the exhaust shell between the filter cover and the support frame. The exhaust blades are fixedly connected to the transmission column at equal intervals. The exhaust blades can drain dust inside the connecting ring to the inner wall of the filter cover.

[0019] In some embodiments, an air duct is fixedly connected to a portion of the exhaust shell close to the support frame, and the air duct can discharge the air inside the exhaust shell to the outside, and a guide portion is provided on the conveying blade.

[0020] The present invention has at least the following beneficial effects:

[0021] 1. When the conveyor belt in the bucket elevator drives the bucket to transport through the limit hinge, the bucket can drive the rice to be transported inside the shell structure. When the bucket throws the rice into the first discharge pipe, the bucket can vibrate downward, which can facilitate the rapid separation of dust adhering to the inside of the bucket.

[0022] 2. When the air intake structure inside the bucket elevator is in use, the air inside the upper air intake cavity can be blown upward under the guidance of the guide end. At this time, the dust inside the shell structure can move upward, which can prevent the dust from contacting the rice at the bottom of the shell structure.

[0023] 3. When the air intake structure inside the bucket elevator is in use, the air entering the lower air intake cavity can blow the rice inside the air guide part to the inside of the guide groove, and the guide groove can also guide the rice to the inside of the hopper.

[0024] 4. After the hopper inside the bucket elevator throws the rice out of the first discharge pipe, the exhaust blades can drain the unqualified rice into the connecting ring. When the unqualified rice enters the connecting ring, the conveying blades can beat the unqualified rice into the second discharge pipe, so that the unqualified rice can be sorted and discharged.

[0025] 5. When the exhaust blades in the bucket elevator are working, the dust inside the shell structure will enter the inside of the connecting ring and the filter cover. At this time, the filter cover can filter the dust inside the shell structure to prevent the dust from gathering inside the shell structure.

[0026] 6. The scraper rod in the bucket elevator can continuously scrape the dust on the inner wall of the filter cover, and the storage groove on the scraper rod can collect the dust on the inner wall of the filter cover, which can avoid the blockage of the air guide plate and realize the rapid penetration of the air inside the shell structure and the air guide plate. At this time, the adhesive plate arranged inside the storage groove can adhere to the dust. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figure 1-4 , the present invention provides a technical solution:

[0042] A small primary agricultural product lifting conveyor comprises a housing structure 2 and a transmission structure 1 connected to the housing structure 2, and further comprises:

[0043] The conveyor belt 7 is distributed inside the shell structure 2, and the upper and lower parts of the conveyor belt 7 are both inserted with rotating parts 11. The rotating part 11 on the upper part of the conveyor belt 7 is fixedly connected to the output end of the transmission structure 1. The outer wall of the conveyor belt 7 is fixedly connected to the limit hinge 9. The end of the limit hinge 9 away from the conveyor belt 7 is fixedly connected to the hopper 8. The limit hinge 9 is used to limit the flipping of the hopper 8 connected to the conveyor belt 7;

[0044] When the transmission structure 1 in the lifting conveyor drives the conveying belt 7 to move through the rotating part 11, the conveying belt 7 can drive the hopper 8 to move through the limit hinge 9, so that the hopper 8 can drive the rice to be lifted and transported inside the shell structure 2. After the rice inside the hopper 8 is scattered inside the first discharge pipe 62, the hopper 8 will flip downward again. At this time, the hopper 8 can vibrate on the conveying belt 7, so that the dust inside the hopper 8 can be discharged.

[0045] Example 2: Please refer to Figure 1-11 , the present invention provides a technical solution:

[0046] The lower part of the shell structure 2 is fixedly connected with a feed end 3 and an air intake structure 5. The feed end 3 includes a feed pipe 31 fixedly connected to the shell structure 2 and a guide groove 32 distributed on the shell structure 2 and located below the feed pipe 31. It also includes an air guide part 33 distributed in the lower part of the shell structure 2. When the air intake structure 5 blows external air to the interior of the air guide part 33, the rice inside the air guide part 33 can enter the interior of the hopper 8 under the guidance of the guide groove 32.

[0047] An exhaust structure 6 is fixedly connected to the top of the shell structure 2, and the exhaust structure 6 includes a first discharge pipe 62 fixedly connected to the shell structure 2, and the first discharge pipe 62 is used to discharge qualified rice to the outside. A connecting ring 65 is fixedly connected to the portion of the shell structure 2 near the first discharge pipe 62, and a second discharge pipe 63 is fixedly connected to the portion of the connecting ring 65 near the first discharge pipe 62, and the connecting ring 65 is used to drain unqualified rice to the inside of the second discharge pipe 63.

[0048] The limiting hinge 9 drives the hopper 8 to flip at an angle between zero and two hundred and twenty-five degrees. The lower part of the shell structure 2 is fixedly connected to the support structure 4, and the first discharge pipe 62 and the second discharge pipe 63 are arranged side by side.

[0049] The air intake structure 5 includes an air intake pipe 51 fixedly connected to the lower part of the shell structure 2 , a splitter 55 is fixedly connected inside the air intake pipe 51 , and a flow guide end 54 is fixedly connected to a portion of the splitter 55 close to the air guide portion 33 .

[0050] The dividing piece 55 can divide the inner cavity of the air inlet pipe 51 into a lower air inlet cavity 52 and an upper air inlet cavity 53. The lower air inlet cavity 52 can guide the external air to the air guide portion 33, and the guide end 54 can guide the air inside the upper air inlet cavity 53 upward.

[0051] When the air intake pipe 51 in the lifting conveyor drives external air into the upper air intake chamber 53, the air inside the upper air intake chamber 53 will move upward under the guidance of the guide end 54. At this time, the dust shaken out by the hopper 8 will move upward, which can avoid the dust discharged from the hopper 8 from contacting the rice at the lower part of the shell structure 2. When the air inside the lower air intake chamber 52 blows against the inside of the air guide part 33, the rice inside the air guide part 33 will enter the inside of the guide groove 32, and then the guide groove 32 can drive the rice into the inside of the hopper 8, so that the rice at the lower part of the shell structure 2 can also be lifted and transported.

[0052] Example 3: Please refer to Figure 1-11 , the present invention provides a technical solution:

[0053] The exhaust structure 6 also includes a connecting bracket 66 fixedly connected between the shell structure 2 and the connecting ring 65 . The connecting bracket 66 is connected to a drainage structure 10 . The drainage structure 10 includes a connecting column 101 . The connecting column 101 is fixedly connected to the output end of the transmission structure 1 .

[0054] One end of the connecting column 101 away from the transmission structure 1 is fixedly connected to a transmission column 105 , a filter cover 64 is sleeved on the transmission column 105 , the filter cover 64 is fixedly connected to the connecting ring 65 , and an air guide sheet 68 is provided on the filter cover 64 .

[0055] The outer wall of the transmission column 105 is fixedly connected with conveying blades 102 and scraping rods 106 at equal intervals, the scraping rod 106 is fixedly connected with a storage groove 108, the interior of the storage groove 108 is fixedly connected with an adhesive plate 109, the conveying blades 102 are distributed inside the connecting ring 65, and the scraping rod 106 abuts against the inner wall of the filter cover 64.

[0056] The end of the connecting ring 65 facing away from the shell structure 2 is fixedly connected to the exhaust shell 61 , and the inner wall of the exhaust shell 61 near the driving column 105 is fixedly connected to the support frame 104 , and the support frame 104 is rotatably connected to the driving column 105 .

[0057] Exhaust blades 103 are distributed inside the exhaust shell 61 between the filter cover 64 and the support frame 104. The exhaust blades 103 are fixedly connected to the transmission column 105 at equal intervals. The exhaust blades 103 can guide the dust inside the connecting ring 65 to the inner wall of the filter cover 64.

[0058] An air duct 67 is fixedly connected to the exhaust shell 61 near the support frame 104. The air duct 67 can discharge the air inside the exhaust shell 61 to the outside. A guide portion 107 is provided on the conveying blade 102.

[0059] After the hopper 8 in the lifting conveyor conveys the rice to the inside of the first discharge pipe 62, the unqualified rice will move in layers inside the first discharge pipe 62. The unqualified rice proposed in this document is light rice and shriveled rice. According to existing common sense, when the light rice and shriveled rice are thrown, they will float. When the floating rice contacts the air guided by the guide end 54, the floating rice will move upward, and then the transmission structure 1 will drive the transmission column 105 to rotate through the connecting column 101. The transmission column 105 drives the exhaust blade 103 to rotate, and the exhaust blade 103 drives the air inside the shell structure 2 to be transported to the air guide pipe 67. When the air guide pipe 67 discharges the air transported by the exhaust blade 103 to the outside, the inside of the exhaust shell 61 is in a negative pressure state. At this time, the lighter rice and the shriveled rice will enter the inside of the connecting ring 65, and then the transport blade 102 will knock the lighter rice and the shriveled rice into the inside of the second discharge pipe 63, so as to realize the sorting and discharge of the lighter rice and the shriveled rice.

[0060] Example 4: Please refer to Figure 1-11 , the present invention provides a technical solution:

[0061] When the transmission column 105 drives the scraper rod 106 and the exhaust paddle 103 to rotate, the interior of the exhaust shell 61 is in a negative pressure state. At this time, the dust inside the shell structure 2 will be filtered by the air guide plate 68, and the scraper rod 106 can continuously scrape the dust on the inner wall of the filter cover 64. The storage groove 108 on the scraper rod 106 can collect the dust on the inner wall of the filter cover 64, which can avoid the blockage of the air guide plate 68 and enable the air inside the shell structure 2 to quickly pass through the air guide plate 68. At this time, the adhesion plate 109 arranged inside the storage groove 108 can adhere to the dust.
