Description

Technical Field

[0001] The present invention relates to the technical field of grain threshing, and specifically to a continuous grain drying and threshing device. Background Art

[0002] Threshing is one of the most important links in the crop harvesting process, which separates the grains of the harvested crop from the ear, and at the same time separates other by-products such as short stalks, glumes, and sundries from the grains as much as possible.

[0003] Referring to the patent with the publication number: CN 222170528 U, named: A Threshing Device, which includes a threshing bin. One side of the threshing bin is fixedly connected with a driving motor, and a gear accelerator is fixedly connected below the threshing bin. The power output end of the driving motor is fixedly connected with a transmission wheel, one end of the transmission wheel is connected to the power input end of the gear accelerator through a transmission belt, the power output end of the gear accelerator is fixedly connected with a fan and a squeezing wheel, a screening area is fixedly connected below the threshing bin, a sieve plate is movably connected below the screening area, one end of the sieve plate is fixedly connected with a squeezing plate, one end of the squeezing plate is fixedly connected with an arc-shaped convex platform, a dust collection pocket is fixedly connected on one side of the screening area, one end of the dust collection pocket is fixedly connected with a filter plate, and limiting rods are fixedly connected on both sides of the screening area; when heavier debris follows the corn kernels and falls onto the sieve plate, the squeezing wheel drives the sieve plate to vibrate repeatedly through the arc-shaped convex platform, and the heavier debris mixed in the corn kernels is shaken off and screened, improving the quality of the corn after threshing.

[0004] However, in the actual use process, there are still some problems:

[0005] Existing equipment still separates the corn cob from the corn kernels by extrusion during peeling. During this process, the corn kernels are easily broken, and secondly, extrusion is also likely to cause the corn cob to break, resulting in debris falling into the interior of the operating mechanism and causing equipment damage. Secondly, the debris is mixed into the corn kernels. Secondly, when threshing, the high water content of the corn leads to an unsatisfactory threshing effect. Existing equipment also has the problem that the threshed corn cobs cannot be processed again at the same time, and need to be re-collected and transported before being processed, thus increasing the operation process and cost and reducing the continuous processing characteristics of the equipment.

[0020] Beneficial effects:

[0021] Compared with the prior art, the continuous grain drying and threshing device has the following beneficial effects:

[0022] First, through the push processing mechanism set in the present invention, the servo motor drives the connecting shaft to rotate. At the same time, the guiding gear is driven to drive the crawler to move towards one end, pushing the corn falling into the processing tank for displacement. During this process, while one end of the push head moves forward, it will pull another push head to slide at the rear end of the processing tank through the crawler. The folding louvre cover follows its connected push head to fold and extend, and at the same time, the limit strip moves along the trajectory of the connected push head. Subsequently, the corn at the front end of the processing tank is pushed into the feeding pipe under force, which is beneficial to ensuring the continuous pushing and peeling of corn, and at the same time avoiding the corn falling into the equipment working area during the operation of the equipment, thus affecting the processing efficiency. Secondly, it reduces the equipment failure rate and ensures the continuity of equipment operation.

[0023] Second, through the threshing mechanism set in the present invention, the rotation of the servo motor drives the two belt wheels connected by the transmission belt to move simultaneously. The worm is driven by the belt wheel to make the two meshing turbines rotate. Subsequently, the corn cob is aligned with the threshing head for threshing operation. After threshing, the corn cob falls from the threshing head, and at the same time, the separated corn kernels are concentrated and collected along the discharge hopper, which is beneficial to ensuring the threshing rate and threshing integrity of the equipment, reducing the operation difficulty of the equipment and improving its automation. Secondly, after threshing, the corn cob enters the conveying pipe from the threshing head and is conveyed to the inside of the collection box. Subsequently, the driving motor is started to drive the crushing roller to crush the corn cob by the driving wheel. Secondly, the conveying pump is started to pump the crushed corn cob out from the bottom of the collection box and sent to an external granulator for compaction granulation, which is beneficial to facilitating the reprocessing of the waste corn cob into livestock feed, saving processing steps and realizing the reuse of resources.

[0024] Third, through the drying mechanism set in the present invention, the heater and the air blower are started. At this time, the air blower blows the generated heat to the main pipe. Secondly, while the main pipe is blowing air, the main air volume is compressed into the air blowing pipe until it blows from the other end to drive the fan blade to rotate. At this time, the sprocket is driven by the fan blade to rotate, and at the same time, the control shaft rotates accordingly. Secondly, the driving disk drives the stripping pieces to rotate rapidly, so as to cooperate with the stirring bars to perform pre-stripping operation on the corn close to the inner wall of the accommodating barrel. The hot air from the main pipe is evenly conveyed into the accommodating barrel through several air outlet pipes. Subsequently, the stirring motor is started to drive the driving shaft to rotate. At this time, the stirring bars are driven to stir and push the corn to the inner wall of the accommodating barrel, which is beneficial to ensuring the sufficient drying of the corn in the accommodating barrel, avoiding the breakage of corn kernels due to too high water content during threshing, and also ensuring that the corn can smoothly fall into the processing tank through the connecting groove. Secondly, it reduces the subsequent stripping difficulty and improves the threshing effect, and at the same time dries the pre-stripped corn cob to reduce the water content of the corn cob.

[0025] Other advantages, objects and features of the present invention will be set forth to some extent in the following description, and to some extent, will be obvious to those skilled in the art from a study of the following, or may be learned from the practice of the present invention.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] As Figure 1-15 shown, the present invention provides a technical solution: a continuous grain drying and threshing device, including a processing bin 1 and a base 2. The processing bin 1 is fixedly connected to the top of the base 2. A bin door 3 is movably connected to one side of the processing bin 1, and a drying mechanism 4 is fixedly connected to the side of the processing bin 1 away from the bin door 3. A feeding port 5 is fixedly connected to one end of the processing bin 1, and a stirring motor 6 is fixedly connected to the end of the processing bin 1 away from the feeding port 5. A receiving barrel 7 is fixedly connected inside the processing bin 1, and the outer wall of the receiving barrel 7 is provided with a hollow setting. Two processing tanks 8 are opened at the bottom end inside the processing bin 1. A pushing and processing mechanism 9 is movably connected inside the processing tank 8. A threshing mechanism 10 is fixedly connected to the other end of the processing tank 8 away from the pushing and processing mechanism 9. A mounting seat 14 is fixedly connected to the end of the processing tank 8 close to the threshing mechanism 10, and a reprocessing mechanism 15 is fixedly connected to the front end of the mounting seat 14.

[0044] As Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 andFigure 7 As shown in the figure, the pushing and processing mechanism 9 includes a pushing head 901, a crawler 902, a limiting strip 903, and a folding shutter cover 904. There are two pushing heads 901, and the limiting strips 903 are respectively fixedly connected to one end of the pushing heads 901. The two ends of the crawler 902 are respectively fixedly connected to one end of different pushing heads 901. The folding shutter covers 904 are respectively fixedly connected to one end of the pushing heads 901. Moreover, the folding shutter covers 904, the crawler 902, and the limiting strips 903 are all located at one end of the pushing heads 901. The pushing heads 901 are adapted to the processing tank 8, and the pushing heads 901 are respectively slidably connected to the inside of the processing tank 8. The folding shutter covers 904 are respectively movably connected to the top of the processing tank 8. And one end of the limiting strip 903 far from the pushing head 901 and the middle bending part of the crawler 902 both extend to the outside of the processing tank 8. The pushing and processing mechanism 9 further includes a servo motor 905, a connecting shaft 906, and a guiding gear 907. The connecting shaft 906 is fixedly connected to the output end of the servo motor 905 through a coupling, and the guiding gear 907 is fixedly connected to one end of the connecting shaft 906 far from the servo motor 905. The servo motor 905 is fixedly connected to one end of the base 2. The guiding gear 907 is rotatably connected to the opposite sides of one end of the two processing tanks 8. The guiding gear 907 is located inside the bending part of the crawler 902, and the guiding gear 907 is meshed with the crawler 902.

[0045] The servo motor 905 drives the connecting shaft 906 to rotate. At the same time, the guiding gear 907 is driven to drive the crawler 902 to move towards one end, pushing the corn that has fallen into the processing tank 8 to displace. During this process, one end of the pushing head 901 moves forward, and at the same time, it will pull another pushing head 901 to slide at the rear end of the processing tank 8 through the crawler 902. The folding shutter cover 904 follows the connected pushing head 901 to fold and stretch. At the same time, the limiting strip 903 follows the trajectory of the connected pushing head 901 to move. Then, the corn at the forefront of the processing tank 8 is pushed into the inside of the feed pipe 1001 under force, which is beneficial to ensuring the continuous pushing and shedding of corn, and at the same time avoiding the corn falling into the equipment working area during the operation of the equipment, thus affecting the processing efficiency. Secondly, it reduces the equipment failure rate and ensures the continuity of equipment operation.

[0046] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 11 and Figure 12As shown in the figure, the threshing mechanism 10 includes a feed pipe 1001, a turbine 1002, a threshing head 1003 and a discharge hopper 1004. The turbine 1002 is movably connected to one end of the feed pipe 1001 through a bearing. The threshing head 1003 is fixedly connected to one side of the turbine 1002 and is located inside the feed pipe 1001. The discharge hopper 1004 is fixedly connected to the outside of the feed pipe 1001 and is in communication with the feed pipe 1001. The threshing mechanism 10 further includes pulleys 1005, a transmission belt 1006 and a worm 1007. There are two pulleys 1005 which are drivingly connected through the transmission belt 1006. The worm 1007 is vertically and fixedly connected to the center position of one of the pulleys 1005. The worm 1007 is located on the opposite side of the turbine 1002 and meshes with the turbine 1002. The other pulley 1005 is fixedly connected to the outside of the connecting shaft 906 and is located directly below the guide gear 907. The reprocessing mechanism 15 includes a collection box 1501, crushing rollers 1502, drive wheels 1503, a drive motor 1504, a delivery pipe 1505 and a delivery pump 1506. There are two crushing rollers 1502 which are movably connected to the inside of the collection box 1501 through rotating shafts. One end of each crushing roller 1502 penetrates through the collection box 1501 and is fixedly connected to the drive wheel 1503. The drive wheels 1503 are drivingly connected by a belt. The drive motor 1504 is fixedly connected to the outside of the collection box 1501 and its output end is fixedly connected to the center of one of the drive wheels 1503.

[0047] When the servo motor 905 rotates, it will drive the two pulleys 1005 connected by the transmission belt 1006 to move simultaneously. The worm 1007 is driven by the pulley 1005 to rotate the two meshing turbines 1002. Then, the corn cobs are aligned with the threshing head 1003 for threshing operation. After the threshing is completed, the corn cobs fall from the threshing head 1003. At the same time, the threshed corn kernels are centrally collected along the discharge hopper 1004, which is beneficial to ensuring the threshing rate and integrity of the equipment, reducing the operation difficulty of the equipment and improving its automation. Secondly, after the threshed corn cobs enter the delivery pipe 1505 from the threshing head 1003 and are transported to the inside of the collection box 1501, the drive motor 1504 is started to drive the crushing rollers 1502 to crush the corn cobs by means of the drive wheels 1503. Secondly, the delivery pump 1506 is started to pump out the crushed corn cobs from the bottom of the collection box 1501 and send them to an external granulator for compaction granulation. This is beneficial to facilitating the reprocessing of waste corn cobs into livestock feed, saving processing steps and realizing the reuse of resources.

[0048] As Figure 1 , Figure 2 , Figure 3 , Figure 10 , Figure 13 , Figure 14 and Figure 15 shown, the drying mechanism 4 includes a blower 401, a heater 402, a main pipe 403 and an air outlet pipe 404. The output end of the blower 401 is fixedly connected to the inside of the heater 402. The main pipe 403 is interconnected with the internal outlet of the heater 402 through a pipe. There are several air outlet pipes 404 and they are fixedly connected to the outside of the main pipe 403. The heater 402 is fixedly connected to the outside of the processing bin 1. The main pipe 403 is horizontally embedded in the inside of the processing bin 1. The air outlet pipes 404 are arc-shaped and are all embedded in the inside of the processing bin 1. And the air outlets of the air outlet pipes 404 all penetrate the processing bin 1 and face the inside of the containing barrel 7. A driving shaft 11 is horizontally arranged inside the containing barrel 7. And the two ends of the driving shaft 11 are respectively movably connected to the inner top end of the processing bin 1 through bearings. The output end of the servo motor 905 penetrates the processing bin 1 and is fixedly connected to one end of the driving shaft 11 through a coupling. Several stirring bars 12 with inconsistent stirring ranges are fixedly connected to the outside of the driving shaft 11. Two symmetric connecting grooves 13 are horizontally opened on the inner wall of the containing barrel 7. And the connecting grooves 13 are adapted to the processing grooves 8. The pre-peeling mechanism 16 includes a driving fan blade 1601, a sprocket 1602, a chain 1603, a control shaft 1604, a driving disk 1605 and peeling pieces 1606. There are two sprockets 1602 and they are connected by a chain 1603. One of the sprockets 1602 is fixedly connected to the axis of the driving fan blade 1601 through a rotating shaft. The control shaft 1604 is fixedly connected to the axis of the other sprocket 1602. Several driving disks 1605 are fixedly connected to the surface of the control shaft 1604 in a neat arrangement. The peeling pieces 1606 are respectively fixedly connected to the outside of the driving disk 1605 in an annular and integral arrangement. The two ends of the control shaft 1604 are movably connected to the inner wall of the processing bin 1 through bearings. An installation groove 17 is opened inside the processing bin 1. And the driving fan blade 1601 and the sprocket 1602 are both movably connected to the inside of the installation groove 17 through bearings. A protective cover 18 is fixedly connected to the outside of the installation groove 17. A blowing pipe 19 is arranged directly above the driving fan blade 1601. And the other end of the blowing pipe 19 sequentially penetrates the protective cover 18 and the heating rack and is fixedly connected to the main pipe 403. The distance between the driving disks 1605 is the same as the grid distance of the containing barrel 7. And the peeling pieces 1606 extend to the inner wall of the containing barrel 7.

[0049] In the present invention, through the provided drying mechanism 4, the heater 402 and the air blower 401 are started. At this time, the air blower 401 blows the generated heat to the main pipe 403. Secondly, while the main pipe 403 is blowing air, the main air volume is compressed into the inside of the blowing pipe 19 until it blows from the other end to drive the drive fan blade 1601 to rotate. At this time, the sprocket 1602 is driven by the drive fan blade 1601 to rotate, and at the same time, the control shaft 1604 rotates accordingly. Secondly, the drive disk 1605 drives the grain stripping pieces 1606 to rotate rapidly, so as to cooperate with the stirring bar 12 to perform pre-grain stripping operation on the corn close to the inner wall of the receiving barrel 7. Several air outlet pipes 404 divide the hot air of the main pipe 403 and evenly transport it towards the inside of the receiving barrel 7. Then, the stirring motor 6 is started to drive the drive shaft 11 to rotate. At this time, the stirring bar 12 is driven to stir and push the corn to the inner wall of the receiving barrel 7, which is beneficial to ensuring that the corn inside the receiving barrel 7 is dried sufficiently, avoiding the crushing of corn kernels caused by too high water content of the corn during threshing, and also ensuring that the corn can smoothly fall into the inside of the processing tank 8 through the connecting groove 13. Secondly, it reduces the subsequent grain stripping difficulty and improves the threshing effect, and at the same time dries the pre-grain stripped corn cob to reduce the water content of the corn cob.

[0050] Working principle: When in use, corn slides from the feeding port 5 into the interior of the receiving barrel 7. At the same time, the heater 402 and the blower 401 are started. At this time, the blower 401 blows the generated heat to the main pipe 403. While the main pipe 403 is blowing air, the main air volume is compressed into the interior of the blowing pipe 19 until it blows from the other end to drive the driving fan blade 1601 to rotate. At this time, the sprocket 1602 is driven by the driving fan blade 1601 to rotate, and at the same time, the control shaft 1604 rotates accordingly. Secondly, the driving disc 1605 drives the grain stripping blades 1606 to rotate rapidly, so as to cooperate with the stirring bars 12 to perform pre-grain stripping operation on the corn close to the inner wall of the receiving barrel 7. Several air outlet pipes 404 distribute the hot air from the main pipe 403 and evenly transport it into the interior of the receiving barrel 7. Then, the stirring motor 6 is started to drive the driving shaft 11 to rotate. At this time, the stirring bars 12 are driven to stir and push the corn to the inner wall of the receiving barrel 7. The corn smoothly falls into the interior of the processing tank 8 through the connecting groove 13. At this time, the servo motor 905 is started to drive the connecting shaft 906 to rotate. At the same time, the guiding gear 907 is driven to drive the crawler 902 to move towards one end, pushing the corn falling into the interior of the processing tank 8 to displace. During this process, one end of the pushing head 901 moves forward to the front end and will pull another pushing head 901 to slide at the rear end of the processing tank 8 through the crawler 902. The folding louver cover 904 follows its connection with the pushing head 901 to fold and extend, and at the same time, the limiting strip 903 moves along the track of the connection with the pushing head 901. Then, the corn at the front end of the processing tank 8 is pushed into the interior of the feeding pipe 1001 under force. Since the pulley 1005 is connected to the outside of the connecting shaft 906, the rotation of the servo motor 905 will drive the two pulleys 1005 connected by the transmission belt 1006 to move simultaneously. The worm 1007 is driven by the pulley 1005 to make the two meshing turbines 1002 rotate. Then, the corn cob is aligned with the threshing head 1003 for threshing operation. After threshing, the corn cob enters the conveying pipe 1505 from the threshing head 1003 and is conveyed into the interior of the collection box 1501. Then, the driving motor 1504 is started to drive the crushing roller 1502 to crush the corn cob by using the driving wheel 1503. Secondly, the conveying pump 1506 is started to pump the crushed corn cob out from the bottom of the collection box 1501 and send it to an external granulator for compaction granulation. At the same time, the separated corn kernels are centrally collected along the discharge hopper 1004.
