[0002] A grain sucker is a mechanical device used to suck, transport and store grain. The main function of a grain sucker is to suck grain from the source and transport it to the target location through a conveying device.

[0003] The patent with application number CN201820469552.0 provides a grain discharge pipe rotating and lifting device for a grain suction machine, including a rotating device and a lifting device. The rotating device includes a shell, a lower flange and an upper discharge pipe. A hydraulic motor, a small gear and a large gear are arranged in the shell. The hydraulic motor is connected to the small gear, and the small gear is meshed with the large gear. The device has a simple structure and ingenious design. The small gear is driven to rotate by the hydraulic motor, and the small gear drives the large gear to rotate. The large gear controls the upper discharge pipe to rotate, and the metal hose also rotates accordingly to achieve the purpose of steering. The hydraulic telescopic rod can control the lifting and lowering of the upper supporting cantilever, thereby controlling the height of the metal hose to achieve the purpose of controlling the discharge height. It is easy to use, can control the direction and height of the discharge, and can be promoted for use. However, the adjustable height and angle of this device are small, and it cannot be used normally for some occasions with large angle requirements. Therefore, an adjustable grain discharge pipe of a pneumatic grain suction machine is proposed to solve the above-mentioned problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an adjustable grain outlet pipe of a pneumatic grain sucking machine in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: an adjustable grain outlet pipe of a pneumatic grain sucking machine, including a vertebral canal, and also including an adjusting device, a separating device, a clearing device and an averaging device; the adjusting device includes a lower support plate, a partition, a connecting rod, a telescopic adjusting rod, a fixing screw, an elastic telescopic rod, a clamping rod, an upper support plate and a rotating block, the lower support plate is fixedly connected to the lower surface of the vertebral canal, the partition is fixedly connected to the right side of the lower support plate, the connecting rod is fixedly connected to the lower surface of another vertebral canal, the telescopic adjusting rod is rotatably connected to the bottom end of the connecting rod, the fixing screw is threadedly connected to the inner wall of the telescopic adjusting rod, the elastic telescopic rod is slidably connected to the inner wall of the lower supporting plate, the clamping rod is fixedly connected to the surface of the elastic telescopic rod, the upper support plate is fixedly connected to the right side of the vertebral canal, and the rotating block is fixedly connected to the upper surface of another vertebral canal; the separating device is arranged on the inner wall of the vertebral canal, the clearing device is arranged on the right side of the separating device, and the averaging device is arranged in the separating device When the adjusting block is extended, the fixing screw is rotated to loosen, and the telescopic adjusting rod can be telescopically adjusted. When the telescopic adjusting rod is contracted, the vertebral canal will rotate downward, and when the telescopic adjusting rod is extended, the vertebral canal will rotate upward. After the adjustment is completed, the fixing screw is tightened again so that the fixing screw fixes and locks the telescopic adjusting rod, thereby limiting and fixing the adjusted vertebral canal. Since the number of vertebral canals is multiple, the adjustment between multiple vertebral canals can achieve large-scale adjustment of angles and heights, and can be suitable for more working environments. The fixing rod on the elastic telescopic rod is inserted into two adjacent telescopic adjusting rods, so that rotating one vertebral canal can drive the remaining vertebral canals to rotate together, which can be more convenient and quick. If a single adjustment is needed, only the corresponding elastic telescopic rod needs to be removed to adjust the single vertebral canal.

[0006] Preferably, the separation device includes a fixed plate, a dual-axis motor, a rotating rod, blades and a filter, the fixed plate is fixedly connected to the inner wall of the vertebral canal, the dual-axis motor is fixedly connected to the left side of the fixed plate, the rotating rod is rotatably connected to the right side of the fixed plate, the blades are fixedly connected to the surface of the rotating rod, and the filter is fixedly connected to the surface of the fixed plate; the separation device also includes an elastic plate, an arc-shaped elastic rod and a rotating plate, the elastic plate is fixedly connected to the inner wall of the blade, the arc-shaped elastic rod is fixedly connected to the surface of the elastic plate, and the rotating plate is rotatably connected to the surface of the blade; the side of the blade away from the rotating rod is in contact with the inner wall of the vertebral canal, the left sides of the elastic plate and the blade are respectively in contact with the right sides of the fixed plate and the filter, the surface of the arc-shaped elastic rod is slidably connected to the inner wall of the blade, and the end of the arc-shaped elastic rod away from the elastic plate is in contact with the rotating The surface of the plate is fixedly connected. When the grain enters the right vertebral canal for discharge, the grain will fall on the filter. The filter will separate the small stones mixed in the grain during the drying process. At the same time, the dual-axis motor will drive the rotating rod to rotate, and the rotating rod will drive the blades to rotate. The blades will push the grain accumulated on the filter to move, thereby improving the screening efficiency of the grain. When the blades rotate, they will drive the elastic plate to rotate, and the elastic plate will push the grain to move. If there are stones, the stones will collide with the elastic plate, causing the elastic plate to deform, which can effectively prevent the blades from contacting the stones and reduce the probability of blade damage. When the elastic plate is deformed, it will drive the arc-shaped elastic rod to move, and the arc-shaped elastic rod will drive the rotating plate to rotate. The rotation of the rotating plate will push and lift the grain pushed by the blades, which can prevent the grain from accumulating on the filter and affecting subsequent screening, while improving the separation and screening effect of the grain.

[0007] Preferably, the dredging device includes a transmission rod, a rotating bar, an elastic rod, a push rod, a fixed rod, a baffle and a clamping plate, the transmission rod is rotatably connected to the inner wall of the rotating rod, the rotating bar is fixedly connected to the right end of the transmission rod, the elastic rod is fixedly connected to the left side of the rotating bar, the push rod is fixedly connected to the right side of the rotating bar, the fixed rod is fixedly connected to the right side of the blade, the baffle is rotatably connected to the inner wall of the vertebral canal, and the clamping plate is rotatably connected to the inner wall of the baffle through a torsion spring; the dredging device also includes a guide block, a support rod, a cam and a movable plate, the guide block is fixedly connected The right side of the baffle is connected to the support rod, the support rod is fixedly connected to the right side of the rotating bar, the cam is fixedly connected to the right end of the support rod, and the movable plate is slidably connected to the inner wall of the guide block through an elastic member; the left end of the transmission rod is fixedly connected to the right output end of the dual-axis motor, the surface of the elastic rod is in contact with the surface of the blade, the right end of the fixed rod is fixedly connected to the left side of the baffle, the surface of the support rod is rotatably connected to the inner wall of the baffle and the guide block respectively, the surface of the movable plate is in contact with the surface of the cam, and the surface of the cam is in contact with the inner wall of the guide block. When too much grain enters at one time, it will accumulate at the filter. At this time, the dual-axis motor will drive the transmission rod to rotate, the transmission rod will drive the rotating bar to rotate, the rotating bar will drive the elastic rod to rotate, and the elastic rod will drive the blades to rotate. When the grain input is greater than the output, it will accumulate at the filter. When too much grain accumulates, the blades will not be able to push the grain to move. At this time, the elastic rod will deform and pass over the blades, causing the rotating bar to drive the elastic rod to continue rotating, and the rotating bar will drive the push rod to rotate. At this time, the blades no longer rotate, so the baffle no longer rotates. At this time, the push rod will push the card plate to rotate, causing the card plate to close the baffle, allowing the grain to The material will no longer be fed. When the grain is discharged from the filter, the blades will continue to be pushed and rotated by the elastic rod. At this time, the torsion spring will drive the card plate to reset and open, and then the material can continue to be fed to prevent the continuous feeding from causing blockage of the spinal canal. The grain entering the spinal canal will pass through the baffle and fall on the filter under the guidance of the guide block. When too much grain is accumulated on the filter, the rotating bar will drive the support rod to rotate, and the support rod will drive the cam to rotate in the guide block. The cam will push the movable plate to move, and the movable plate will extend out of the guide block, thereby lifting and blocking the grain outside the guide block, reducing the grain from continuing to move toward the filter.

[0008] Preferably, the averaging device includes a rotating disk and sieve holes, the rotating disk is fixedly connected to the left output end of the dual-axis motor, and the sieve holes are opened on the surface of the rotating disk; the averaging device also includes an elastic telescopic plate, a brush plate, a brush rod and an arc block, the elastic telescopic plate is fixedly connected to the left side of the fixed plate, the brush plate is fixedly connected to the left side of the elastic telescopic plate, the brush rod is fixedly connected to the left side of the brush plate, and the arc block is fixedly connected to the right side of the rotating disk. The food passing through the filter will fall on the rotating disk. At this time, the other output end of the dual-axis motor will drive the rotating disk to rotate, and the rotating disk will rotate the food accumulated on the surface, so that the food falls from the sieve holes relatively evenly and enters the next vertebral canal, preventing multiple vertebral canals from being formed. When adjusting in an arc shape, the grain will fall on one side of the filter in the next vertebral canal due to inertia after falling, causing the grain to be unevenly distributed in the next vertebral canal and accumulate in one place, which can easily affect the rotation effect of the blades. At the same time, when the rotating disk rotates, it will drive the grain to contact the brush plate on the fixed plate and the brush rod on its surface. At this time, the brush rod can further scrape and disperse the grain, further improving the uniformity of grain discharge. At the same time, the rotation of the rotating disk will drive the arc block to move, and the arc block will push the brush plate to move through the arc surface, and the brush plate will push the elastic telescopic plate to contract. When the arc block passes the brush plate, the elastic telescopic plate will reset under the action of the spring and drive the brush plate to move downward. The brush plate will drive the brush rod to move and extend into the sieve hole, which can also play a role in clearing the sieve hole.

[0009] The present invention adopts the above technical solution to bring the following beneficial effects:

[0010] 1. The adjustable grain discharge pipe of the pneumatic grain suction machine cooperates with the spinal canal, the lower support plate, the partition, the connecting rod, the telescopic adjustment rod, the fixed screw, the elastic telescopic rod, the clamping rod, the upper support plate and the rotating block. When adjustment is needed, the fixed screw is rotated loose, and the telescopic adjustment rod can be telescopically adjusted. When the telescopic adjustment rod contracts, the spinal canal will rotate downward, and when the telescopic adjustment rod is extended, the spinal canal will rotate upward. After the adjustment is completed, the fixed screw is tightened again so that the fixed screw fixes and locks the telescopic adjustment rod, thereby limiting and fixing the adjusted spinal canal. Since there are multiple spinal canals, the adjustment between the multiple spinal canals can achieve a large adjustment of angle and height, so that it can be applied to more working environments.

[0011] 2. The adjustable grain discharge pipe of the pneumatic grain suction machine works through the coordination of the fixed plate, dual-axis motor, rotating rod, blades, elastic plate, arc-shaped elastic rod, rotating plate and filter. When the grain enters the right vertebral canal for discharge, the grain will fall on the filter, and the filter will separate the small stones mixed in the grain during the drying process. At the same time, the dual-axis motor will drive the rotating rod to rotate, and the rotating rod will drive the blades to rotate. The blades will push the grain accumulated on the filter to move, thereby improving the screening efficiency of the grain.

[0012] 3. The adjustable grain discharge pipe of the pneumatic grain suction machine cooperates with the transmission rod, rotating bar, elastic rod, push rod, fixed rod, baffle, card plate, guide block, support rod, cam and movable plate to operate. When too much grain enters at one time, it will accumulate at the filter screen. At this time, the dual-axis motor will drive the transmission rod to rotate, the transmission rod will drive the rotating bar to rotate, the rotating bar will drive the elastic rod to rotate, and the elastic rod will drive the blades to rotate. When the grain feed is greater than the discharge, it will accumulate at the filter screen. When the accumulation is too much, the blades will not be able to push the grain to move. At this time, the elastic rod will deform and pass over the blade, so that the rotating bar will drive the elastic rod to continue to rotate, and the rotating bar will drive the push rod to rotate. At this time, the blades no longer rotate, so the baffle no longer rotates. At this time, the push rod will push the card plate to rotate, so that the card plate and the baffle are closed, so that grain will no longer be fed. After the grain is discharged from the filter screen, the blade will continue to be pushed and rotated by the elastic rod. At this time, the torsion spring will drive the card plate to reset and open, so that the feeding can continue to prevent continuous feeding from causing blockage of the spinal canal.

[0013] 4. The adjustable grain outlet pipe of the pneumatic grain suction machine cooperates with the rotating disk, sieve holes, elastic telescopic plates, brush plates, brush rods, and arc blocks. The grain that passes through the filter will fall on the rotating disk. At this time, the other output end of the dual-axis motor will drive the rotating disk to rotate. The rotating disk will rotate the grain accumulated on the surface, so that the grain falls from the sieve holes relatively evenly and enters the next vertebral canal to prevent the grain from falling on one side of the filter in the next vertebral canal due to inertia when multiple vertebral canals are adjusted in an arc shape, resulting in uneven distribution of grain in the next vertebral canal and accumulation in one place, which easily affects the rotation effect of the blades.

[0025] See also Figure 1-4An embodiment of the present invention is: an adjustable grain outlet pipe of a pneumatic grain sucker, including a spinal canal 1, and also including an adjusting device, a separating device 7, a dredging device 8 and an equalizing device 9; the adjusting device includes a lower support plate 2, a partition 21, a connecting rod 3, a telescopic adjusting rod 4, a fixing screw 5, an elastic telescopic rod 51, a clamping rod 52, an upper support plate 6 and a rotating block 61, the lower support plate 2 is fixedly connected to the lower surface of the spinal canal 1, the partition 21 is fixedly connected to the right side of the lower support plate 2, and the connecting rod 3 is fixedly connected to the other spinal canal 1 On the lower surface, the telescopic adjustment rod 4 is rotatably connected to the bottom end of the connecting rod 3, the fixed screw 5 is threadedly connected to the inner wall of the telescopic adjustment rod 4, the elastic telescopic rod 51 is slidably connected to the inner wall of the lower support plate 2, the clamping rod 52 is fixedly connected to the surface of the elastic telescopic rod 51, the upper support plate 6 is fixedly connected to the right side of the vertebral canal 1, and the rotating block 61 is fixedly connected to the upper surface of another vertebral canal 1. When adjustment is needed, the fixed screw 5 is rotated and loosened, and the telescopic adjustment rod 4 can be telescopically adjusted at this time. When the telescopic adjustment rod 4 contracts, the vertebral canal 1 will rotate downward. When the telescopic adjustment rod 4 is extended, the vertebral canal 1 will rotate upward. After the adjustment is completed, the fixing screw 5 is tightened again so that the fixing screw 5 fixes and locks the telescopic adjustment rod 4, thereby limiting and fixing the adjusted vertebral canal 1; the separation device 7 is arranged on the inner wall of the vertebral canal 1, the dredging device 8 is arranged on the right side of the separation device 7, and the equalization device 9 is arranged on the left side of the separation device 7; the left end of the telescopic adjustment rod 4 is rotatably connected to the inner wall of the partition 21, the surface of the clamping rod 52 is slidably connected to the inner wall of the telescopic adjustment rod 4, and the inner wall of the bottom of the upper support plate 6 is rotatably connected to the top of the rotating block 61. Since there are multiple vertebral canals 1, the adjustment between multiple vertebral canals 1 can achieve a large adjustment of angle and height, and thus can be applied to more working environments. The clamping rod 52 on the elastic telescopic rod 51 is inserted into two adjacent telescopic adjustment rods 4, so that the rotation of one vertebral canal 1 can drive the remaining vertebral canals 1 to rotate together, which can be more convenient and quick. If a single adjustment is required, only the corresponding elastic telescopic rod 51 needs to be removed to adjust a single vertebral canal 1;

[0026] The separation device 7 includes a fixed plate 71, a dual-axis motor 72, a rotating rod 73, a blade 74 and a filter 75. The fixed plate 71 is fixedly connected to the inner wall of the spinal canal 1, the dual-axis motor 72 is fixedly connected to the left side of the fixed plate 71, the rotating rod 73 is rotatably connected to the right side of the fixed plate 71, the blade 74 is fixedly connected to the surface of the rotating rod 73, and the filter 75 is fixedly connected to the surface of the fixed plate 71. When the grain enters the right spinal canal 1 for grain discharge, the grain will fall on the filter 75, and the filter 75 will filter the grain. During the drying process, the mixed small stones are separated, and at the same time, the dual-axis motor 72 drives the rotating rod 73 to rotate, and the rotating rod 73 drives the blade 74 to rotate, and the blade 74 pushes the food accumulated on the filter screen 75 to move, thereby improving the food screening efficiency; the separation device 7 also includes an elastic plate 741, an arc-shaped elastic rod 742 and a rotating plate 743, the elastic plate 741 is fixedly connected to the inner wall of the blade 74, the arc-shaped elastic rod 742 is fixedly connected to the surface of the elastic plate 741, and the rotating plate 743 rotates The blade 74 is movably connected to the surface of the blade 74. When the blade 74 rotates, it drives the elastic plate 741 to rotate. The elastic plate 741 pushes the food to move. If there are stones, the stones will collide with the elastic plate 741, causing the elastic plate 741 to deform, which can effectively prevent the blade 74 from contacting the stone and reduce the probability of damage to the blade 74. When the elastic plate 741 is deformed, it drives the arc-shaped elastic rod 742 to move. The arc-shaped elastic rod 742 drives the rotating plate 743 to rotate. The rotation of the rotating plate 743 will move the blade 74. 4, the grains pushed by the blade 74 are lifted up, which can prevent the grains from piling up on the filter screen 75 and affecting the subsequent screening, and at the same time improve the separation and screening effect of the grains; the side of the blade 74 away from the rotating rod 73 is in contact with the inner wall of the vertebral canal 1, the left side of the elastic plate 741 and the blade 74 are in contact with the right side of the fixed plate 71 and the filter screen 75 respectively, the surface of the arc-shaped elastic rod 742 is slidably connected with the inner wall of the blade 74, and the end of the arc-shaped elastic rod 742 away from the elastic plate 741 is fixedly connected with the surface of the rotating plate 743;

[0027] Working principle: when adjustment is needed, the fixing screw 5 is rotated loose, and the telescopic adjustment rod 4 can be telescopically adjusted at this time. When the telescopic adjustment rod 4 contracts, the vertebral canal 1 will rotate downward, and when the telescopic adjustment rod 4 is extended, the vertebral canal 1 will rotate upward. After the adjustment is completed, the fixing screw 5 is tightened again so that the fixing screw 5 can fix and lock the telescopic adjustment rod 4, and then the adjusted vertebral canal 1 is limited and fixed. Since there are multiple vertebral canals 1, the adjustment between multiple vertebral canals 1 can achieve a large adjustment of angle and height, and can be suitable for more working environments. The clamping rod 52 on the elastic telescopic rod 51 is inserted into two adjacent telescopic adjustment rods 4, so that rotating one vertebral canal 1 can drive the remaining vertebral canals 1 to rotate together, which can be more convenient and quick. If a single adjustment is required, only the corresponding elastic telescopic rod 51 needs to be removed to adjust the single vertebral canal 1.

[0028] When grain enters the right vertebral canal 1 for discharging, the grain will fall on the filter screen 75, and the filter screen 75 will separate the small stones mixed in the grain during the drying process. At the same time, the dual-axis motor 72 will drive the rotating rod 73 to rotate, and the rotating rod 73 will drive the blade 74 to rotate. The blade 74 will push the grain accumulated on the filter screen 75 to move, thereby improving the screening efficiency of the grain. When the blade 74 rotates, it will drive the elastic plate 741 to rotate, and the elastic plate 741 will push the grain to move. If there are stones, the stones will collide with the elastic plate 741, causing the elastic plate 741 to deform, which can effectively prevent the blade 74 from contacting the stone and reduce the probability of damage to the blade 74. When the elastic plate 741 is deformed, it will drive the arc spring rod 742 to move, and the arc spring rod 742 will push the rotating plate 743 to rotate. The rotation of the rotating plate 743 will push and lift the grain pushed by the blade 74, which can prevent the grain from accumulating on the filter screen 75 and affecting subsequent screening, while improving the separation and screening effect of the grain.

When too much food enters at one time, it will accumulate at the filter screen 75. At this time, the dual-axis motor 72 will drive the transmission rod When the food is fed into the filter screen 75, the food will accumulate on the filter screen 75. When the food accumulates too much, the food will not be able to move. At this time, the elastic rod 83 will deform and pass over the blade 74, so that the rotating bar 82 will drive the elastic rod 83 to continue to rotate. The rotating bar 82 will drive the push rod 84 to rotate. At this time, the blade 74 will no longer rotate, so the baffle 86 will no longer rotate. At this time, the push rod 84 will push the card plate 87 to rotate, so that the card plate 87 will close the baffle 86, so that the food will no longer be fed. After the food on the filter screen 75 is discharged, the blade 74 will continue to be pushed by the elastic rod 83 to rotate. The dredging device 8 also includes a guide block 871, a support rod 872, a cam 873 and a movable plate 874. The guide block 871 is fixedly connected to the right side of the baffle 86, the support rod 872 is fixedly connected to the right side of the rotating bar 82, the cam 873 is fixedly connected to the right end of the support rod 872, and the movable plate 874 is slidably connected to the inner wall of the guide block 871 through an elastic member. The food entering the vertebral canal 1 will pass through the baffle 86 under the guidance of the guide block 871 and fall on the filter screen 75. When too much food is accumulated on the filter screen 75, the rotating bar 82 will drive the support rod 872 to rotate, and the support rod 872 will The cam 873 is driven to rotate in the guide block 871, and the cam 873 will push the movable plate 874 to move, and the movable plate 874 will extend out of the guide block 871, thereby lifting and blocking the grain outside the guide block 871, reducing the grain from continuing to move toward the filter screen 75; the left end of the transmission rod 81 is fixedly connected to the right output end of the dual-axis motor 72, the surface of the elastic rod 83 and the surface of the blade 74 are in contact with each other, the right end of the fixed rod 85 is fixedly connected to the left side of the baffle 86, the surface of the support rod 872 is rotatably connected to the baffle 86 and the inner wall of the guide block 871 respectively, the surface of the movable plate 874 and the surface of the cam 873 are in contact with each other, and the surface of the cam 873 and the inner wall of the guide block 871 are in contact with each other;

[0030] The averaging device 9 includes a rotating disk 91 and a sieve hole 92. The rotating disk 91 is fixedly connected to the left output end of the dual-axis motor 72. The sieve hole 92 is opened on the surface of the rotating disk 91. The grain passing through the filter screen 75 will fall on the rotating disk 91. At this time, the other output end of the dual-axis motor 72 will drive the rotating disk 91 to rotate. The rotating disk 91 will rotate the grain accumulated on the surface, so that the grain falls from the sieve hole 92 relatively evenly and enters the next vertebral canal 1 to prevent the grain from falling on one side of the filter screen 75 in the next vertebral canal 1 due to inertia when multiple vertebral canals 1 are adjusted in an arc shape, resulting in uneven distribution of the grain in the next vertebral canal 1 and accumulation in one place, which easily affects the rotation effect of the blade 74; the averaging device 9 also includes an elastic telescopic plate 921, a brush plate 922, a brush rod 923 and an arc block 924. The elastic telescopic plate 921 is fixedly connected to the fixed plate 71.

When the rotating disk 91 rotates, it will drive the grain to contact the brush plate 922 on the fixed plate 71 and the brush rod 923 on its surface. At this time, the brush rod 923 can further scrape and disperse the grain, further improving the uniformity of grain discharge. At the same time, the rotation of the rotating disk 91 will drive the arc block 924 to move, and the arc block 924 will push the brush plate 922 to move through the arc surface, and the brush plate 922 will push the elastic telescopic plate 921 to contract.

[0031] Working principle: when too much grain enters at one time, it will accumulate at the filter screen 75. At this time, the dual-axis motor 72 will drive the transmission rod 81 to rotate, the transmission rod 81 will drive the rotating bar 82 to rotate, the rotating bar 82 will drive the elastic rod 83 to rotate, and the elastic rod 83 will drive the blade 74 to rotate. When the grain feed is greater than the discharge, it will accumulate at the filter screen 75. When too much grain is accumulated, the blade 74 will not be able to push the grain to move. At this time, the elastic rod 83 will deform and pass over the blade 74, so that the rotating bar 82 will drive the elastic rod 83 to continue to rotate, and the rotating bar 82 will drive the push rod 84 to rotate. At this time, the blade 74 no longer rotates, so the baffle 86 no longer rotates. At this time, the push rod 84 will push the card plate 87 to rotate, so that the card plate 87 and the baffle 86 are closed, so that the grain Food will no longer be fed. When the food on the filter screen 75 is discharged, the blade 74 will continue to be pushed and rotated by the elastic rod 83. At this time, the torsion spring will drive the clamping plate 87 to reset and open, so that the food can continue to be fed to prevent the continuous feeding from causing blockage of the vertebral canal 1. The food entering the vertebral canal 1 will pass through the baffle 86 under the guidance of the guide block 871 and fall on the filter screen 75. When too much food is accumulated on the filter screen 75, the rotating bar 82 will drive the support rod 872 to rotate, and the support rod 872 will drive the cam 873 to rotate in the guide block 871. The cam 873 will push the movable plate 874 to move, and the movable plate 874 will extend out of the guide block 871, thereby lifting and blocking the food outside the guide block 871, reducing the food from continuing to move toward the filter screen 75.

[0032] The grains passing through the filter screen 75 will fall on the rotating disk 91. At this time, the other output end of the dual-axis motor 72 will drive the rotating disk 91 to rotate. The rotating disk 91 will rotate the grains accumulated on the surface, so that the grains fall relatively evenly from the sieve holes 92 and enter the next vertebral canal 1, to prevent the grains from falling on one side of the filter screen 75 in the next vertebral canal 1 due to inertia when multiple vertebral canals 1 are adjusted in an arc shape, resulting in uneven distribution of the grains in the next vertebral canal 1 and accumulation in one place, which is easy to affect the rotation effect of the blades 74. At the same time, when the rotating disk 91 rotates, it will drive the grains to contact the brush plate 9 on the fixed plate 71. 22 and the brush rod 923 on its surface, at this time, the brush rod 923 can further scrape and disperse the grain, further improving the uniformity of grain discharge, and at the same time, the rotation of the rotating disk 91 will drive the arc block 924 to move, and the arc block 924 will push the brush plate 922 to move through the arc surface, and the brush plate 922 will push the elastic telescopic plate 921 to contract. When the arc block 924 passes over the brush plate 922, the elastic telescopic plate 921 will reset under the action of the spring and drive the brush plate 922 to move downward, and the brush plate 922 will drive the brush rod 923 to move and extend into the sieve hole 92, and can also play a role in clearing the sieve hole 92.
