[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the downward pressure of the supply component causes the opening component to operate, and a long opening is cut at the bottom of the sack containing grain, so that the grain inside the sack is poured out through the long opening, thereby eliminating the need to open the bag manually, thereby improving the convenience of grain transportation.

[0020] 2. In the present invention, the telescopic cross bar is driven to move upward through the connecting block by the connecting angle code, and the movement of the telescopic cross bar drives the ratchet bar to move upward. Due to the one-way meshing action of the ratchet bar and the ratchet wheel, the upward movement of the ratchet bar will drive the ratchet wheel to rotate. The rotation of the ratchet wheel further drives the path cam to rotate together through the rotating shaft. The rotation of the path cam and the guide wheel produce a cam effect, and cooperate with the sliding connection between the vibration slide bar and the fixed enclosure plate and the elastic action of the vibration spring, so that when the path cam rotates continuously, the feeding frame vibrates back and forth, and transmits the vibration to the bag holding frame through the fixed angle code, the conveying vertical rod and the connecting angle code. Therefore, the bag holding frame drives the four positioning steel needles and the sack fixed between the four positioning steel needles to vibrate together. Through the vibration of the sack, the grain inside the sack can be poured out cleanly to avoid grain residue in the sack, which is conducive to more thorough pouring of the grain inside the sack.

DETAILED DESCRIPTION

[0033] 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.

[0034] See also Figure 1-Figure 11 The technical solution provided by the present invention specifically includes the following embodiments:

[0035] Embodiment 1: A conveying device for grain processing production, comprising a fixed frame 1, the number of the fixed frames 1 is two, and the two fixed frames 1 are distributed front and back, a conveyor 2 is provided between the two fixed frames 1, and a fixed enclosure 3 is fixedly installed on the top of the two fixed frames 1, a supply component 4 is provided between the two fixed enclosures 3, an opening component 5 is provided inside the supply component 4, a material shaking component 6 is provided on the front of the supply component 4, a platform 7 is fixedly installed on the left part of the two fixed frames 1, and a protective fence is provided on the top of the platform 7;

[0036] The supply component 4 includes a feeding frame 401, and a fixed angle code 402 is fixedly installed on the upper front and back of the feeding frame 401. Two conveying vertical rods 403 distributed on the left and right are slidably installed inside the fixed angle code 402. The conveying vertical rods 403 movably penetrate the top and bottom of the fixed angle code 402. A connecting angle code 404 is fixedly installed on the top of the two conveying vertical rods 403 distributed on the left and right. There are two connecting angle codes 404 in total, and a bag holding frame 405 is fixedly installed between the two connecting angle codes 404. Positioning steel needles 4010 are fixedly installed at the four corners of the top of the bag holding frame 405. A funnel 408 is fixedly installed at the bottom of the feeding frame 401, and a cloth cover 409 is fixedly installed at the bottom of the funnel 408.

[0037] Specifically, in this embodiment, a worker stands on the top of the platform 7 to work, lifts up the grain sack and places it on the top of the bag supporting frame 405, and four positioning steel needles 4010 just pierce into the four corners of the sack to fix the sack. After the sack is placed on the top of the bag supporting frame 405, the weight of the grain is applied to the bag supporting frame 405 to move downward, and the bag supporting frame 405 moves downward and drives the conveying vertical rod 403 to move downward along the fixed angle code 402 through the connecting angle code 404. Further, under the sliding guiding action of the conveying vertical rod 403 and the fixed angle code 402, the stability and smoothness of the downward sliding of the bag supporting frame 405 are guaranteed, and a long opening is cut at the bottom of the sack through the opening component 5, and the grain inside the sack is poured out through the long opening, and is supplied to the top of the conveyor 2 through the feeding frame 401, the funnel 408 and the cloth cover 409, and then transported out through the conveyor 2. There is no need to manually hold the sack to pour the grain, which reduces the labor intensity of the workers.

[0038] Furthermore, the periphery of the conveying vertical rod 403 is sleeved with a first spring 406, and the first spring 406 is fixedly installed between the fixed angle code 402 and the connecting angle code 404. When the connecting angle code 404 moves downward, the first spring 406 is compressed, and the first spring 406 is sleeved on the periphery of the conveying vertical rod 403. Therefore, after the first spring 406 is compressed, it will not bend significantly due to the limiting effect of the conveying vertical rod 403. As the grain inside the sack continues to pour out, the remaining grain inside the sack gradually decreases, so the gravity pressure on the bag supporting frame 405 gradually decreases, and the rebound force of the first spring 406 is upward. The bag supporting rack 405 is pushed to move, and the bag supporting rack 405 moves upward to reset, waiting for the next sack of grain to be poured. A telescopic cover 407 is fixedly installed between the bottom of the bag supporting rack 405 and the top of the feeding frame 401. By installing the telescopic cover 407 between the bag supporting rack 405 and the feeding frame 401, the gap between the bag supporting rack 405 and the feeding frame 401 can be sealed, so that during the process of pouring grain, the grain will not overflow from the gap between the feeding frame 401 and the bag supporting rack 405. At the same time, the telescopic cover 407 is made of soft and retractable rubber material and will not interfere with the normal up and down movement of the bag supporting rack 405.

[0039] Embodiment 2: The opening component 5 includes four derivation cylinders 501 fixedly installed at the four corners of the outer wall of the feeding frame 401, and push rods 502 are slidably installed inside the four derivation cylinders 501. The push rods 502 are movable through the feeding frame 401 and extend into the inside thereof. A tool holder 503 is fixedly installed on one end of the push rods 502 located inside the feeding frame 401, and a blade 504 is fixedly installed on the top of the tool holder 503. There are four blades 504. A derivation piston 505 is fixedly installed on one end of the push rod 502 away from the tool holder 503, and the outer wall of the derivation piston 505 is slidably connected to the inner wall of the derivation cylinder 501.

[0040] The opening component 5 also includes a pressure storage cylinder 506 fixedly installed at the bottom of the fixed angle bracket 402, and there are two pressure storage cylinders 506 at the bottom of the same fixed angle bracket 402, and the two pressure storage cylinders 506 are distributed on the left and right, and a pressure storage piston 507 is slidably installed on the inner wall of the pressure storage cylinder 506, and the pressure storage piston 507 is fixedly installed at the bottom of the conveying vertical rod 403. An air guide hole 508 is opened through the bottom of the pressure storage cylinder 506, and an air guide pipe 509 is fixedly installed between the outer periphery of the bottom opening of the air guide hole 508 and the input end of the derivation cylinder 501;

[0041] The opening component 5 also includes four guide seats 5010 fixedly installed at the four corners of the top of the feeding frame 401, and two telescopic suspension rods 5011 are slidably installed inside the guide seats 5010. The two telescopic suspension rods 5011 are movable through the top and bottom of the guide seats 5010, and the telescopic suspension rods 5011 are located on both sides of the tool holder 503. The bottoms of the two telescopic suspension rods 5011 are commonly connected to a bracket 5012, and a wedge block 5013 is fixedly installed on the top of the bracket 5012. A wedge groove 5014 is opened at the bottom of the tool holder 503, and the wedge block 5013 is clamped inside the wedge groove 5014. Pressing plates 5016 are fixedly installed at the four corners of the bottom of the bag holding frame 405, and the position of the pressing plate 5016 corresponds to the position of the telescopic suspension rod 5011.

[0042] Specifically, in this embodiment, when the grain ballast conveying vertical rod 403 moves downward, it drives the pressure storage piston 507 to move downward along the inner wall of the pressure storage cylinder 506, thereby compressing the air inside the pressure storage cylinder 506. Since the air inside the pressure storage cylinder 506 is compressed, the damping value of the downward movement of the pressure storage piston 507 increases accordingly, that is, the speed of the downward movement of the pressure storage piston 507 gradually slows down, further causing the downward speed of the conveying vertical rod 403, the fixed angle code 402 and the bag supporting frame 405 to gradually slow down, so that when the bag supporting frame 405 moves downward and drives the pressure plate 5016 to move to contact the top of the telescopic boom 5011, no impact sound is emitted, and at the same time, damage caused by rapid contact and impact between the pressure plate 5016 and the telescopic boom 5011 is avoided, thereby reducing the noise of the device operation and increasing the service life of the device.

[0043] When the bag support frame 405 drives the pressure plate 5016 to move downward to the top of the telescopic boom 5011, the bottom of the grain sack is just pierced by the four blades 504, and then the pressure plate 5016 presses the telescopic boom 5011 downward, causing the telescopic boom 5011 to move downward, and through the connection action of the bracket 5012, the wedge block 5013 is driven downward to move, causing the wedge block 5013 to move out from the inside of the wedge groove 5014, thereby releasing the limiting effect on the knife holder 503. Therefore, the compressed air inside the pressure storage cylinder 506 is compressed to the inside of the derivation cylinder 501 through the air guide hole 508 and the air guide pipe 509, pushing the derivation piston 505 to move along the inside of the derivation cylinder 501 toward the feeding box 401, further pushing the push rod 502 together with the knife holder 503 and the blade 504 to move, and the blade 504 moves to the middle position of the feeding box 401, A long opening is cut at the bottom of the sack, and the grain inside the sack pours out through the long opening, and is supplied to the top of the conveyor 2 through the feeding box 401, the funnel 408 and the cloth cover 409, and then is transported out through the conveyor 2. As the grain inside the sack continues to pour out, the remaining grain inside the sack gradually decreases, so the gravity pressure on the bag supporting frame 405 gradually decreases, and the rebound force of the first spring 406 pushes the bag supporting frame 405 upward to move. The bag supporting frame 405 moves upward, and the connection between the fixed angle code 402 and the conveying vertical rod 403 drives the pressure storage piston 507 to move upward along the inner wall of the pressure storage cylinder 506, and the air inside the derivation cylinder 501 is sucked into the inside of the pressure storage cylinder 506 through the air guide pipe 509. Therefore, the derivation piston 505 is subjected to the negative pressure inside the derivation cylinder 501 and slides along the inside of the derivation cylinder 501 in a direction away from the feeding box 401.

[0044] Furthermore, the outer periphery of the telescopic suspension rod 5011 is sleeved with a second spring 5015, and the second spring 5015 is fixedly installed between the bottom of the guide seat 5010 and the top of the bracket 5012. When the telescopic suspension rod 5011 moves downward to drive the bracket 5012 to move downward, the second spring 5015 is stretched and stores force. Therefore, when the pressure plate 5016 moves upward to release the downward pressure on the top of the telescopic suspension rod 5011, the rebound force of the second spring 5015 can achieve the upward resetting effect of the telescopic suspension rod 5011, the bracket 5012 and the wedge block 5013, so that the wedge block 5013 can be stuck in the wedge groove 5014 again, thereby limiting the reset tool holder 503.

[0045] Embodiment 3: The material shaking component 6 includes a connecting block 601 fixedly installed at the bottom of one of the connecting angle codes 404, and two telescopic cross bars 602 distributed up and down are slidably installed inside the connecting block 601. The two telescopic cross bars 602 movably penetrate the front and back of the connecting block 601, and the ends of the two telescopic cross bars 602 away from the feeding frame 401 are jointly fixedly installed with a ratchet 603, and the outer periphery of one of the telescopic cross bars 602 is provided with a third spring 604, and the third spring 604 is fixedly installed between the connecting block 601 and the ratchet 603;

[0046] The material shaking component 6 also includes two shaft frames 605 fixedly mounted on the top of the fixed angle code 402, the two shaft frames 605 are distributed on the left and right, and a rotating shaft 606 is rotatably mounted between the two shaft frames 605, a ratchet 607 is fixedly mounted on the outer wall of the rotating shaft 606, the ratchet 607 is unidirectionally meshed with the ratchet bar 603, and two path cams 6012 distributed on the left and right are fixedly mounted on the outer wall of the rotating shaft 606, wherein two wheel frames 608 distributed on the left and right are fixedly mounted on the upper part of the inner side surface of a fixed enclosure 3 close to the material shaking component 6, and a guide wheel 609 is rotatably mounted on the side surface of the two wheel frames 608 through a pin shaft, and the outer wall of the guide wheel 609 abuts against the outer wall of the path cam 6012;

[0047] The material shaking component 6 also includes two vibration slide bars 6010 fixedly installed on the front of the feeding frame 401, and two vibration slide bars 6010 fixedly installed on the back of the feeding frame 401. The two vibration slide bars 6010 are distributed left and right, and the vibration slide bars 6010 moveably penetrate the interior of the fixed enclosure 3 in the corresponding direction, and are slidably connected with the through holes of the fixed enclosure 3. The periphery of the vibration slide bars 6010 is sleeved with vibration springs 6011, and the vibration springs 6011 are fixedly installed between the fixed enclosure 3 and the feeding frame 401;

[0048] Specifically, in this embodiment, the upward movement of the connecting angle code 404 also drives the telescopic cross bar 602 to move through the connecting block 601, and the movement of the telescopic cross bar 602 drives the ratchet 603 to move upward. Due to the one-way meshing action of the ratchet 603 and the ratchet wheel 607, the upward movement of the ratchet 603 drives the ratchet wheel 607 to rotate. The rotation of the ratchet wheel 607 further drives the path cam 6012 to rotate together through the rotating shaft 606. The rotation of the path cam 6012 produces a cam effect with the guide wheel 609, and cooperates with the sliding connection between the vibration slide bar 6010 and the fixed enclosure 3. Due to the elastic effect of the vibration spring 6011, the path cam 6012 causes the feeding frame 401 to vibrate back and forth when it rotates continuously, and transmits the vibration to the bag supporting rack 405 through the fixed angle code 402, the conveying vertical rod 403 and the connecting angle code 404. Therefore, the bag supporting rack 405 drives the four positioning steel needles 4010 and the sack fixed between the four positioning steel needles 4010 to vibrate together. Through the vibration of the sack, the grain inside the sack can be poured out cleanly to avoid grain residue in the sack, which is conducive to more thorough pouring of the grain inside the sack.

[0049] When the conveying device for grain processing and production of the present invention is working, the worker stands on the top of the platform 7 to carry the grain sack and put it on the top of the bag support frame 405. The four positioning steel needles 4010 just pierce the four corners of the sack to fix the sack. After the sack is placed on the top of the bag support frame 405, the ballasted bag support frame 405 moves downward under the action of the gravity of the grain. The bag support frame 405 moves downward and drives the conveying vertical rod 403 to move downward along the fixed angle code 402 through the connecting angle code 404. Further, under the sliding guiding action of the conveying vertical rod 403 and the fixed angle code 402, the stability and smoothness of the downward sliding of the bag support frame 405 are guaranteed. At the same time, the downward movement of the conveying vertical rod 403 also drives the pressure storage piston 507 It moves downward along the inner wall of the pressure storage cylinder 506, thereby compressing the air inside the pressure storage cylinder 506. Since the air inside the pressure storage cylinder 506 is compressed, the damping value of the pressure storage piston 507 moving downward increases accordingly, that is, the speed of the pressure storage piston 507 moving downward gradually slows down, further causing the conveying vertical rod 403, the fixed angle code 402 and the bag support frame 405 to gradually slow down the downward speed, so that when the bag support frame 405 moves downward and drives the pressure plate 5016 to move to contact the top of the telescopic boom 5011, no impact sound will be made, and at the same time, damage caused by rapid contact and impact between the pressure plate 5016 and the telescopic boom 5011 is avoided, thereby reducing the noise of the device operation and increasing the service life of the device;

[0050] When the bag support frame 405 drives the pressure plate 5016 to move downward to the top of the telescopic suspension rod 5011, the bottom of the grain sack is just pierced by the four blades 504, and then the pressure plate 5016 presses down the telescopic suspension rod 5011, causing the telescopic suspension rod 5011 to move downward, and drives the wedge block 5013 to move downward through the connection effect of the bracket 5012, causing the wedge block 5013 to move out from the inside of the wedge groove 5014, thereby releasing the limiting effect on the knife holder 503. Therefore, the compressed air in the pressure storage cylinder 506 is discharged through the air guide holes 508, The air guide tube 509 is compressed to the inside of the derivation cylinder 501, pushing the derivation piston 505 to move along the inside of the derivation cylinder 501 toward the feeding box 401, further pushing the push rod 502 together with the knife holder 503 and the blade 504 to move, and the blade 504 moves to the middle position of the feeding box 401, cutting a long hole in the bottom of the grain sack, and the grain inside the sack is poured out through the long hole, and is supplied to the top of the conveyor 2 through the feeding box 401, the funnel 408 and the cloth cover 409, and then transported out through the conveyor 2;

[0051] As the grain inside the sack is continuously poured out, the remaining grain inside the sack gradually decreases, so the gravity pressure on the bag support frame 405 gradually decreases, and the rebound force of the first spring 406 pushes the bag support frame 405 upward to move, and the bag support frame 405 moves upward, and through the connection between the fixed angle code 402 and the conveying vertical rod 403, the pressure storage piston 507 is driven to move upward along the inner wall of the pressure storage cylinder 506, and the air inside the derivation cylinder 501 is sucked into the inside of the pressure storage cylinder 506 through the air guide pipe 509. Therefore, the derivation piston 505 is affected by the negative pressure inside the derivation cylinder 501 and slides along the inside of the derivation cylinder 501 in the direction away from the feeding box 401, and drives the knife holder 503 and the blade 504 to reset through the push rod 502, and the wedge block 5013 is again stuck in the inside of the wedge groove 5014 under the elastic force of the second spring 5015;

[0052] The upward movement of the connecting angle code 404 also drives the telescopic cross bar 602 to move through the connecting block 601, and the movement of the telescopic cross bar 602 drives the ratchet 603 to move upward. Due to the unidirectional meshing action of the ratchet 603 and the ratchet wheel 607, the upward movement of the ratchet 603 drives the ratchet wheel 607 to rotate. The rotation of the ratchet wheel 607 further drives the path cam 6012 to rotate together through the rotating shaft 606. The rotation of the path cam 6012 produces a cam effect with the guide wheel 609, and cooperates with the sliding connection between the vibration slide bar 6010 and the fixed enclosure 3 and the elastic action of the vibration spring 6011, so that the path When the cam 6012 continues to rotate, the feeding frame 401 vibrates back and forth, and transmits the vibration to the bag supporting rack 405 through the fixed angle code 402, the conveying vertical rod 403 and the connecting angle code 404. Therefore, the bag supporting rack 405 drives the four positioning steel needles 4010 and the sack fixed between the four positioning steel needles 4010 to vibrate together. Through the vibration of the sack, the grain inside the sack can be poured out to avoid grain residue in the sack. When the grain inside the sack is completely poured out, the worker removes the sack from the top of the four positioning steel needles 4010 and can continue to add sacks filled with grain upwards.

[0053] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
