Description

Technical Field

[0001] The invention relates to an agricultural machine, in particular to a seedling separation mechanism during planting. Background Art

[0002] In the existing crop planting, crop transplanting generally adopts the manual transplanting method, which has a large workload and low work efficiency. It needs to be further improved. Summary of the invention

[0003] The purpose of the invention is to provide an automatic seedling separation mechanism which is easy to operate and has high working efficiency.

[0004] The technical solution of the present invention is:

[0005] An automatic seedling separation mechanism, characterized in that it comprises a lifting part and a retracting and unfolding part; the lifting part comprises a tooling platform, a lifting airbag or a lifting cylinder, a retracting and unfolding platform support column, and a lifting plate guide column are mounted on the tooling platform, a push rod is fixed to the lifting plate through a push rod fixing plate, the retracting and unfolding platform is mounted at the ends of the retracting and unfolding platform support column and the lifting plate guide column, and a seedling pot positioning column support plate is mounted on the upper surface of the retracting and unfolding platform;

[0006] The retractable and deployable part includes a guide column mounting plate, the guide column mounting plate and the electric slide are mounted on the retractable and deployable platform, the guide column is mounted on the guide column mounting plate, the guide bar fixing plate is mounted on the guide column, the seedling guide bar is mounted on the guide bar fixing plate, adjacent guide bar fixing plates are connected with the short hinge rod and the long hinge rod by step bolts, the short hinge rod and the long hinge rod and the axle pin form a scissor fork type equidistant variable distance structure; the traction connecting plate is fixed on the slide seat of the electric slide and is simultaneously connected to the guide bar fixing plate at the end.

[0007] A lower limit block of the jacking plate is installed on the tooling table; an oil-free bushing is fixed on the jacking plate; an upper limit block of the jacking plate is installed on the lower surface of the storage and deployment platform; and a seedling pot positioning column support plate is installed on the upper surface of the storage and deployment platform through a positioning column support plate support block.

[0008] Working method: During operation, in the initial state of the seedling separator mechanism, the seedling pot positioning columns gather at one corner of the mechanism. After each seedling pot positioning column is placed on the seedling pot, the electric slides on the left and right sides drive the horizontal guide bar fixing plate in the guide bar fixing plate to move. The distance accuracy is ensured by the electric slide composed of the scissor-fork type equidistant variable pitch structure and the servo motor and the ball screw. When the horizontal seedling pot guide strip in the seedling pot guide strip is in place, the electric slides on the front and rear sides drive the longitudinal guide bar fixing plate in the guide bar fixing plate to move, and the longitudinal seedling pot guide strip in the seedling pot guide strip moves into place.

[0009] After the seedling pot is unfolded into place under the drive of the seedling pot positioning column, the axis of the push rod, the axis of the seedling pot positioning column and the axis of the seedling pot coincide with each other. At this time, the lifting airbag begins to inflate. As the amount of inflation continues to increase, the lifting plate is gradually lifted up, or the lifting cylinder gradually lifts the lifting plate. When the lifting plate rises, it drives the push rod to move upward, and finally the magnet at the end of the push rod pushes the seedling pot gasket to push the seedlings out of the seedling pot; after the seedlings are removed, the lifting airbag begins to exhaust, or the lifting cylinder retracts, and the lifting plate descends under the action of gravity. The magnet will absorb the seedling pot gasket when it descends, thus ensuring that the seedling pot gasket is finally at the bottom of the seedling pot.

[0010] The invention has the advantages of convenient operation and high working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] An automatic seedling separation mechanism comprises a lifting part 1 and a retracting and unfolding part 2.

[0021] The lifting part includes a platform fixing part 11, a tooling table 12, a lifting airbag 13, a retracting and unfolding platform support column 14, a lifting plate 15, a lifting plate guide column 16, an oil-free bushing 17, a top rod fixing plate 18, a top rod 19, a lifting limit block 110, a retracting and unfolding platform 111, a positioning column support plate support block 112, and a seedling pot positioning column support plate 113; the lifting airbag 13, the retracting and unfolding platform support 14, the lifting plate guide column 16 and the lifting plate lower limit The positioning blocks 114 are all installed on the workbench 12, the oil-free bushing 17 is fixed on the jacking plate 15, the push rod 19 is fixed on the jacking plate through the push rod fixing plate 18, the storage and deployment platform 111 is installed at the ends of the storage and deployment platform support column 14 and the jacking plate guide column 16, the jacking plate upper limit block 110 is installed on the lower surface of the storage and deployment platform 111, and the seedling pot positioning column support plate 113 is installed on the upper surface of the storage and deployment platform 111 through the positioning column support plate support block.

[0022] The stowage and deployment part includes a guide column mounting plate 21, an electric slide 22, a guide column 23, a short hinge rod 24, a long hinge rod 25, a seedling bowl positioning column 26, a seedling bowl guide strip 27, a traction connecting plate 28, and a guide strip fixing plate 29; the guide column mounting plate 21 and the electric slide 22 are installed on the stowage and deployment platform 111, the guide column 23 is installed on the guide column mounting plate 21, the guide strip fixing plate 29 is installed on the guide column 23, and the seedling bowl guide strip is installed on the guide strip fixing plate 29. The adjacent guide strip fixing plates 29 are connected to the short hinge rod 24 and the long hinge rod 25 with step bolts, and the traction connecting plate 28 is fixed on the slide seat of the electric slide 22 and is connected to the guide strip fixing plate 29 at the end.

[0023] During operation, the initial state of the seedling separator mechanism is as follows: Figure 4 As shown, the seedling pot positioning columns 26 are gathered at a corner of the mechanism. When each seedling pot positioning column 26 is placed on the seedling pot 31, the seedling pot 31 is formed. Figure 5 The electric slides 22 on the left and right sides drive the horizontal guide bar fixing plate 29 to move, and the distance accuracy is ensured by the scissor-fork type equidistant variable distance structure composed of the hinge rods 24, 25 and the shaft pin and the electric slide composed of the private service motor and the ball screw. When the horizontal seedling bowl guide bar 27 is in place, the electric slides 22 on the front and rear sides drive the longitudinal guide bar fixing plate 29 to move. The state after the longitudinal seedling bowl guide bar 27 moves into place is Figure 6 shown.

[0024] After the seedling pot 31 is deployed in place under the drive of the seedling pot positioning column 26, the axis of the push rod 19, the axis of the seedling pot positioning column 26, and the axis of the seedling pot coincide with each other, and the lifting air bag 13 starts to be inflated. As the inflation amount continues to increase, the lifting plate 15 will be gradually lifted up. While the lifting plate 15 is lifted up, the push rod 19 is driven to move upward, and finally the magnet 115 at the end of the push rod supports the seedling pot pad 32 to push the seedlings out of the seedling pot. After the seedlings are removed, the lifting air bag 13 starts to exhaust, and the lifting plate 15 descends under the action of gravity. The magnet 115 will absorb the seedling pot pad when it descends, so as to ensure that the seedling pot pad 32 is finally at the bottom of the seedling pot 31. The lifting air bag can be replaced by a lifting cylinder.
