The existing special equipment for intelligent transportation of agricultural products can quickly transfer agricultural products between various processing steps, which is very convenient. However, it still has certain deficiencies, that is, after the special equipment for intelligent transportation of agricultural products is used, a certain amount of residue will remain on the conveyor belt, which requires staff to clean it. On the one hand, the traditional manual cleaning method makes the cleaning work intensity of the staff relatively large, and on the other hand, the cleaning work efficiency is relatively low, and the conveyor belt cannot be cleaned conveniently and quickly, making the use of the special equipment for intelligent transportation of agricultural products have certain inconvenience. Summary of the Invention

[0005] A product conveying equipment for mechanized agriculture includes a conveying frame. A conveyor belt is installed on the conveying frame, and a movable cleaning component is installed at the end of the conveying frame. The movable cleaning component moves to the upper side of the conveyor belt to clean it;

[0006] A residue pushing mechanism is installed on the movable cleaning component. After the conveyor belt is cleaned, the residue pushing mechanism can push out the residue, and a sealing component is also installed on the movable cleaning component;

[0007] The sealing component can seal the movable cleaning mechanism to prevent the residue from falling, and the residue pushing mechanism can push the sealing component to rotate;

[0008] The sealing component is connected with an upward pushing mechanism, and the upward pushing mechanism can drive the sealing component to move upward to achieve the smooth cleaning of the residue on the conveyor belt.

[0009] Preferably, the movable cleaning component is a cleaning carrier strip, and when the cleaning carrier strip does not clean the conveyor belt, it does not contact the conveyor belt on the conveying frame.

[0010] Preferably, a cleaning carrier plate is fixedly arranged on one side of the end of the conveying frame, and a hydraulic rod is installed on the cleaning carrier plate;

[0011] The hydraulic rod member is fixedly connected to the cleaning carrier strip, and the cleaning carrier strip is driven to move by the hydraulic rod member.

[0012] Preferably, the residue pushing mechanism is a movable slag pushing plate, and the movable slag pushing plate is connected to the cleaning carrier plate. When the cleaning carrier strip moves, the movable slag pushing plate is driven to move.

[0013] Preferably, the sealing component includes a movable plate strip and a movable slag baffle, and the movable plate strip is installed on the cleaning carrier strip.

[0014] Preferably, a pressing plate strip is fixedly arranged on the movable slag pushing plate, and the movable slag pushing plate can limit the movable plate strip through the pressing plate strip.

[0015] Preferably, the movable slag baffle is installed on the movable plate strip, and the movable slag baffle is connected to the movable slag pushing plate.

[0016] Preferably, when the movable slag pushing plate moves, it can drive the movable slag baffle to rotate to push out the residue.

[0017] Preferably, a cooperating bearing rod is arranged on the movable slag pushing plate, and a pushing carrier block and a limiting block are fixedly arranged on the cooperating bearing rod.

[0018] Preferably, the pushing carrier block pushes the movable slag baffle to rotate, and the limiting block plays a role in limiting the movable slag baffle.

[0019] Preferably, the upward pushing mechanism includes an upward driving plate and a connecting upward push rod. The upward driving plate is installed on the cleaning carrier strip, and the upward driving plate is connected to the movable plate strip through the connecting upward push rod.

[0020] Preferably, when the movable plate strip moves up and down, it drives the movable slag baffle to move up and down synchronously.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably arranged and has strong functionality, and has the following advantages:

[0022] 1. A cleaning carrier plate is provided on the conveying frame, and cleaning strips are installed on the cleaning carrier plate. When the conveyor belt needs to be cleaned, the hydraulic rod drives the cleaning strips to move onto the conveyor belt. Under the action of the cleaning inclined surface, the residues on the conveyor belt can be scraped off and collected on the residue receiving plate, thereby realizing the cleaning of the residues on the conveyor belt. And under the action of the second movable baffle and the movable retaining platform, the residues can be limited to prevent them from falling from both sides of the conveying frame. During the process of the conveyor belt transporting agricultural products, the first movable baffle and the movable retaining platform are located on both sides of the conveying frame and cooperate with the side retaining strips on both sides of the conveying frame, which can play a good limiting role on the transported agricultural products and prevent the agricultural products from slipping from both sides of the conveying frame. When the cleaning strips clean the conveyor belt on the conveying frame, at this time, the movable retaining platform and the second movable baffle are located on both sides of the conveying frame and cooperate with the side retaining strips on both sides of the conveying frame, which can play a good limiting role on the residues and prevent the residues from slipping from both sides of the conveying frame.

[0023] 2. When the cleaning strips move onto the conveyor belt, the upward movement drive plate will contact the limiting plate strip. Under the limitation of the limiting plate strip, as the cleaning strips move, it will drive the upward movement drive plate to move towards the direction of the movable retaining platform, and then drive the movable plate strip to move upward. As the movable plate strip moves upward, it will also drive the movable slag retaining plate to move upward to ensure the smooth cleaning of the residues. After cleaning the residues, as the cleaning strips move back in the reverse direction, the movable slag retaining plate moves downward to reset, and the residues can be restricted on the residue receiving plate to prevent them from falling onto the conveyor belt again.

[0024] 3. In addition, as the cleaning strips further reset, the movable slag pushing plate will move. As the movable slag pushing plate moves, it will move the residues towards the direction of the cleaning inclined surface. At the same time, under the action of the pushing block, it will push the movable slag retaining plate to rotate so that it is no longer closed at the cleaning inclined surface. In this way, the residues can slide off the residue receiving plate to achieve collection, which is very convenient. During the reverse movement of the cleaning strips after cleaning the residues, the limiting block can play a limiting role on the movable slag retaining plate to make it maintain a vertical state, so that the movable slag retaining plate can play a good limiting role on the residues.

[0040] As Figure 4 shown, side retaining strips 12 are symmetrically and fixedly arranged on both sides of the conveying frame 1, and a limiting plate strip 13 is fixedly arranged on the side retaining strip 12 on one side of the conveying frame 1.

[0041] As Figure 1 and Figure 8 shown, the movable cleaning component is a cleaning carrier strip 2. When the cleaning carrier strip 2 does not clean the conveyor belt 11, it does not contact the conveyor belt 11 on the conveying frame 1. A first movable baffle 21 is fixedly arranged at one end of the cleaning carrier strip 2, a second movable baffle 22 is fixedly arranged at the other end, and a movable retaining platform 23 is also fixedly arranged on the cleaning carrier strip 2 between the first movable baffle 21 and the second movable baffle 22. A plugging and bearing hole 24 is formed on the movable retaining platform 23, and a residue bearing plate 25 is fixedly arranged between the movable retaining platform 23 and the second movable baffle 22. A cleaning inclined surface part 26 is arranged on the residue bearing plate 25, and guiding rods 27 and bearing guide rods 28 are fixedly arranged on both the movable retaining platform 23 and the second movable baffle 22.

[0042] As Figure 4 shown, a cleaning carrier plate 14 is fixedly arranged on one side of the end of the conveying frame 1, a hydraulic rod 15 is installed on the cleaning carrier plate 14, and a matching bearing plate strip 16 is also fixedly arranged on the cleaning carrier plate 14. A displacement channel 17 and a locking channel 18 are arranged on the matching bearing plate strip 16, the displacement channel 17 and the locking channel 18 are connected, and their widths are equal.

[0043] As Figure 2 and Figure 3 shown, the hydraulic rod 15 is fixedly connected with the cleaning carrier strip 2, the hydraulic rod 15 drives the cleaning carrier strip 2 to move, and the hydraulic rod 15 is fixedly connected with the second movable baffle 22 on the cleaning carrier strip 2.

[0044] As Figure 2 , Figure 6 and Figure 10As shown, the residue pushing mechanism is the movable slag pushing plate 3. The movable slag pushing plate 3 is connected to the cleaning carrier plate 14. When the cleaning carrier bar 2 moves, it drives the movable slag pushing plate 3 to move. On the movable slag pushing plate 3, connecting plates 35 are symmetrically and fixedly arranged. On the connecting plates 35, connecting bar strips 36 are fixedly arranged. At both ends of the connecting bar strips 36, mating guide holes 37 are symmetrically formed. In the mating guide holes 37, bearing guide rods 28 are inserted. And on the connecting bar strips 36, displacement connecting columns 38 are also fixedly arranged. The displacement connecting columns 38 are inserted into the displacement channels 17, and the displacement connecting columns 38 are in contact with the inner walls of the displacement channels 17.

[0045] As Figure 1 , Figure 5 , Figure 9 and Figure 11 As shown, the sealing component includes a movable bar strip 4 and a movable slag blocking plate 5. The movable bar strip 4 is installed on the cleaning carrier bar 2. On the movable bar strip 4, a pressing position mating groove 41 is formed. And at both ends of the movable bar strip 4, movable guide blocks 42 are symmetrically and fixedly arranged. In the movable guide blocks 42, movable guide holes 43 are formed. In the movable guide holes 43, limiting guide rods 27 are inserted. And on the movable guide blocks 42, mounting bearing holes 44 are also formed. On one of the movable guide blocks 42 on the movable bar strip 4, a connecting convex plate 45 is fixedly arranged.

[0046] As Figure 9 and Figure 10 As shown, on the movable slag pushing plate 3, a pressing position bar strip 31 is fixedly arranged. The movable slag pushing plate 3 can limit the movable bar strip 4 through the pressing position bar strip 31, that is, when the movable slag pushing plate 3 limits the movable bar strip 4, it is inserted into the pressing position mating groove 41, so that the movable bar strip 4 cannot move upward.

[0047] As Figure 7 and Figure 11 As shown, the movable slag blocking plate 5 is installed on the movable bar strip 4, and the movable slag blocking plate 5 is connected to the movable slag pushing plate 3. On the movable slag blocking plate 5, a rotating channel 51 is formed. And at both ends of the movable slag blocking plate 5, mounting bearing columns 52 are symmetrically and fixedly arranged. The mounting bearing columns 52 are inserted into the mounting bearing holes 44.

[0048] As Figure 5 and Figure 10 As shown, when the movable slag pushing plate 3 moves, it can drive the movable slag blocking plate 5 to rotate to realize the pushing out of the residue. On the movable slag pushing plate 3, a mating bearing rod 32 is arranged. On the mating bearing rod 32, a pushing top bearing block 33 and a limiting block 34 are fixedly arranged. The mating bearing rod 32 is inserted into the rotating channel 51. The pushing top bearing block 33 is inside the movable slag blocking plate 5, and the limiting block 34 is outside the movable slag blocking plate 5.

[0049] As Figure 5 and Figure 10As shown, the pushing load block 33 pushes the movable slag baffle 5 to rotate, and the limiting block 34 plays a role in limiting the movable slag baffle 5. When the movable slag baffle 5 is in a vertical state, the limiting block 34 contacts the movable slag baffle 5 to prevent the movable slag baffle 5 from rotating.

[0050] As Figure 7 shown, the upward moving pushing mechanism includes an upward moving driving plate 6 and a connecting upper push rod 62. The upward moving driving plate 6 is installed on the cleaning load bar 2, and the upward moving driving plate 6 is connected to the moving plate bar 4 through the connecting upper push rod 62. When the moving plate bar 4 moves up and down, it drives the movable slag baffle 5 to move up and down synchronously. An inserting bearing rod 61 is fixedly arranged on the upward moving driving plate 6. The inserting bearing rod 61 is inserted into the inserting bearing hole 24. The upper end of the upward moving driving plate 6 is hinged to the connecting upper push rod 62, and the upper end of the connecting upper push rod 62 is hinged to the connecting convex plate 45.

[0051] When the conveying rack 1 has completed the conveyance of agricultural products and the conveyor belt 11 needs to be cleaned, the hydraulic rod 15 is activated at this time to drive the cleaning carrier strip 2 to move, so that the residue bearing plate 25 on the cleaning carrier strip 2 moves onto the conveyor belt 11 and comes into contact with the conveyor belt 11. In this way, when cleaning the conveyor belt 11, only need to activate the conveyor belt 11 to make it move, and under the action of the cleaning inclined surface 26, the residue on the surface of the conveyor belt 11 can be scraped and cleaned, so that the residue accumulates on the residue bearing plate 25. When the conveyor belt 11 is not being cleaned, the first movable baffle 21 and the movable retaining platform 23 cooperate with the side retaining strip 12 at this time, which can play a role in limiting the agricultural products and prevent the agricultural products from sliding off both sides of the conveying rack 1. During the process of cleaning the conveyor belt 11, the second movable baffle 22 and the movable retaining platform 23 are respectively located on both sides of the conveying rack 1 and cooperate with the side retaining strip 12, which can play a good role in restricting the residue on the conveyor belt 11 and prevent the residue from sliding off both sides of the conveying rack 1. When the residue bearing plate 25 is located on one side of the conveying rack 1, the movable slag retaining plate 5 is in an inclined state at this time, so that there is a gap between the movable slag retaining plate 5 and the residue bearing plate 25. At this time, the pushing carrier block 33 on the supporting rod 32 is in contact with the movable slag retaining plate 5. When the residue bearing plate 25 moves onto the conveyor belt 11, under the cooperation of the displacement channel 17 and the displacement connecting column 38, it will drive the movable slag pushing plate 3 to move away from the movable slag retaining plate 5. In this way, under the action of the self-gravity of the movable slag retaining plate 5, the movable slag retaining plate 5 will rotate and turn downward to a vertical state until the displacement connecting column 38 moves into the locking channel 18. When the movable slag retaining plate 5 is in a vertical state, it is in contact with the residue bearing plate 25, and the limiting block 34 is in contact with the movable slag retaining plate 5 at this time, so as to prevent the movable slag retaining plate 5 from rotating in the reverse direction. As the cleaning carrier strip 2 moves, the upward movement driving plate 6 on the cleaning carrier strip 2 will come into contact with the limiting plate strip 13 on the side retaining strip 12. Under the restriction of the limiting plate strip 13, the upward movement driving plate 6 will be kept stationary. As the cleaning carrier strip 2 moves, the distance between the upward movement driving plate 6 and the movable retaining platform 23 will become smaller. Under the action of the connecting upper push rod 62, it will push the moving plate strip 4 to move upward. As the moving plate strip 4 moves upward, it will also drive the movable slag retaining plate 5 to move upward synchronously. In this way, there will be a distance between the movable slag retaining plate 5 and the conveyor belt 11, so as to ensure that the cleaning inclined surface 26 can clean the conveyor belt 11 smoothly. After the cleaning of the conveyor belt 11 is completed, the hydraulic rod 15 is activated to drive the cleaning carrier strip 2 to move in the reverse direction for resetting. During the reverse movement and resetting process of the cleaning carrier strip 2, the movable slag retaining plate 5 will move downward under the action of gravity until the upward movement driving plate 6 is separated from the limiting plate strip 13, and at this time, the movable slag retaining plate 5 also moves down to the final position. Under the action of the movable slag retaining plate 5, the residue on the residue bearing plate 25 can be limited to prevent it from sliding onto the conveyor belt again during the movement of the cleaning carrier strip 2.Since the movable slag baffle 5 is in contact with the limiting block 34 at this time, it can maintain a stable vertical state under the limitation of the limiting block 34 and the residue bearing plate 25, and can well limit the residue to ensure that the residue will not leak. When the residue bearing plate 25 moves to one side of the conveyor frame 1, the displacement connecting column 38 also moves into the displacement channel 17. In this way, under the cooperation of the displacement connecting column 38 and the displacement channel 17, the movable slag pushing plate 3 will be driven to move in the direction of the movable slag baffle 5. During the movement of the movable slag pushing plate 3, the pressure plate strip 31 on the movable slag pushing plate 3 will be inserted into the pressure fitting groove 41, so as to limit the movable plate strip 4 and prevent it from moving upward. As the movable slag pushing plate 3 continues to move, the pushing block 33 on the cooperation support rod 32 will contact the movable slag baffle 5. Under the action of the pushing block 33, the movable slag baffle 5 will be pushed to rotate, so that a gap is formed between the movable slag baffle 5 and the residue bearing plate 25. At the same time, the movable slag pushing plate 3 will also push the residue on the residue bearing plate 25 to move in the direction of the cleaning inclined surface 26, so that the residue is concentrated at the cleaning inclined surface 26. As the movable slag baffle 5 rotates, the residue loses its limitation, and the residue will slide off the residue bearing plate 25 under the action of its own gravity. It is only necessary to place a receiving container below it in advance to receive the residue, which is very convenient, greatly improves the working efficiency of cleaning the conveyor belt 11, and also reduces the working intensity of the staff in cleaning the conveyor belt 11, which is very practical.

[0052] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
