[0076] In a specific embodiment, as Figure 6The cutting assembly mounting member 51 has a bearing, and the cutting assembly 57 is positioned by a clamping screw on the bearing.

The cutting power transmission assembly 54 can be a chain wheel box, and the cutting power reversing assembly 55 is a gear box, which realizes 1:1 transmission by two groups of gears and changes the rotation direction.

[0077] The cutting power transmission path is as follows: the power is transmitted to the cutting power transmission assembly 54 through the chain wheel on the power shaft 105, then to the cutting power transmission shaft 53, and then to the cutting shaft 573 through the cutting power reversing assembly 55, so as to drive the cutting assembly 57 to continuously cut the seedling mat, and the mat part of the seedling mat is cut into strips by the joint action of the seedling pressing mechanism 1. After the cutting power reversing assembly 55, the rotation direction of the cutting assembly 57 is opposite to the movement direction of the driving motor 101, so that the rotation of the cutting blade 571 has a tendency to push the pot mat seedling 2 to the conveying direction.

[0078] On the basis of the above embodiment, in another embodiment of the present application, as shown in Figure 3The driving mechanism further comprises a support connecting rod 104 and a servo adjusting device 106, and the seedling pushing mechanism 4 further comprises an angle sensor 46 and a controller.

One end of the servo adjusting device 106 is hinged with the servo adjusting device connecting piece 107, and the other end is hinged with the support connecting rod 104.

[0080] When the pushing seedling instruction is completed, the angle sensor 46 installed on the driving shaft mounting member 41 detects the angle of the driving shaft 42, and the detected signal is transmitted to the controller of the device. The processed signal is transmitted to the servo adjusting device 106. If the angle of the driving shaft 42 exceeds or is lower than the predetermined value, the servo adjusting device 106 adjusts the positions of the driving motor 101, the motor connecting plate 102, the coupling 103, the supporting connecting rod 104, the power shaft 105 and the components installed on the power shaft 105, drives the position adjustment of the power shaft 105. The position adjustment of the power shaft 105 changes the contact time of the pushing seedling cam 412 and the cam contact member 413, thereby changing the pushing seedling distance of the next time, and avoiding the generation of accumulated pushing seedling error.

[0081] On the basis of the above-mentioned embodiments, in another embodiment of the present application, as shown in Figure 8 and Figure 9 , the seedling pressing mechanism 1 comprises a seedling pressing mounting member 11 and a seedling pressing strip 12.

The distance between two adjacent seedling fixing blocks 71 matches the distance between two adjacent seedling pressing strips 12. The seedling pressing strip 12 is arranged above the seedling fixing block 71. The pushing seedling mechanism 4 pushes the cut block-shaped seedlings into the space between the seedling fixing block 71 and the seedling pressing strip 12.

[0082] In a specific embodiment, as shown in Figure 8 , the seedling pressing mounting member 11 and the fixing assembly mounting member 72 are connected to the mounting support plate 3 by bolts. The distance between two adjacent seedling fixing blocks 71 is slightly larger than the size of the pot body of the pot body blanket seedling 2 and slightly smaller than the size of the cut pot body blanket seedling 2. The distance between the seedling fixing block 71 and the seedling pressing strip 12 is slightly lower than the height of the blanket part of the pot body blanket seedling 2. The cut seedlings can be pushed into the space between the seedling fixing block 71 and the seedling pressing strip 12 by the subsequent seedlings. The seedling fixing assembly 7 and the seedling pressing assembly 1 jointly form a seedling clamping device, which clamps the cut seedlings on the mounting support plate 3 to prevent them from falling freely.

[0083] On the basis of the above-mentioned embodiments, in another embodiment of the present application, as shown in Figure 10 and Figure 11, the batch seedling mechanism 8 comprises a seedling power reversing assembly 81, a seedling power transmission assembly 82, a seedling assembly mount 83 and a seedling assembly 84, the seedling assembly 84 comprises a seedling positioning baffle 841, seedling prongs 842, a baffle connecting block 843 and a seedling shaft 844, the seedling shaft 844 is rotatably connected to the installation support base 3 through the seedling assembly mount 83, the seedling positioning baffle 841 is fixed to the seedling shaft 844 through the baffle connecting block 843, the seedling prongs 842 are uniformly distributed on the seedling shaft 844, the seedling prongs 842 arranged at intervals are at a predetermined included angle, the seedling power reversing assembly 81 and the seedling power transmission assembly 82 are fixed to the installation support base 3, the input end and the output end of the seedling power reversing assembly 81 are connected with the cutting shaft 573 and the seedling power transmission assembly 82 respectively, the output end of the seedling power transmission assembly 82 is connected with the seedling shaft 844, the seedling positioning baffle 841 cooperates with the seedling fixing block 71 and the seedling strip 12 to block the blocky seedlings between the seedling fixing block 71 and the seedling strip 12, and the seedling prongs 842 are used for prying the blocky seedlings blocked between the seedling fixing block 71 and the seedling strip 12 into the seedling separating mechanism 9.

[0084] In a specific embodiment, as Figure 10 and Figure 11 The shell of the seedling power reversing assembly 81 is fixed to the installation support base 3 by bolts, and the seedling prongs 842 are uniformly distributed on the seedling shaft 844, and each seedling prong 842 is at an included angle of 120°.

[0085] The seedling positioning baffle 841 is used for assisting the accurate conveying of the blanket seedlings 2, so that the movement amount of the seedlings after each seedling pushing tends to be the same, when the seedling pushing cam 412 is in contact with the cam contact piece 413, the seedling positioning baffle 841 on the seedling assembly 84 is also rotated to a position flush with the installation support base 3, and when the seedling pushing cam 412 is out of contact with the cam contact piece 413, the seedling positioning baffle 841 on the seedling assembly 84 is out of the position flush with the installation support base 3 after completing a seedling pushing instruction.

[0086] The power transmission route is as follows: the power transmission to the cutting shaft 573 is transmitted to the seedling power reversing assembly 81, and after being reversed by the seedling power reversing assembly 81, the power is transmitted to the seedling power transmission assembly 82, and is output from the seedling shaft 844, so as to make the seedling assembly 84 move.

[0087] On the basis of the above-mentioned embodiment, in another embodiment of the present application, as Figure 12The seedling separating mechanism 9 comprises a seedling falling bucket 91, a seedling falling bucket connecting piece 92, and a guide pipe 93, the guide pipe 93 is connected with the seedling falling bucket 91 through the seedling falling bucket connecting piece 92, the seedling falling bucket 91 is fixed on the mounting support seat 3, the seedling prongs 842 are arranged in three groups, are uniformly arranged in the circumferential direction with an interval of 120°, and are arranged at equal intervals in the axial direction according to the size of the pot body blanket seedlings 2. The seedling prongs 842 complete a seedling pronging operation once every rotation of the seedling shaft 844. The seedling prongs 842 in the scheme are 15 in total and are divided into five groups, three in each group. When the seedling prongs 842 rotate for the first 120°, the corresponding 1, 4, 7, 10, and 13 seedlings are pronged out, and the seedlings are pronged into the seedling falling bucket 91 and complete the first group of seedling throwing through the guide pipe 93. When the seedling prongs 842 rotate for the second 120°, the corresponding 2, 5, 8, 11, and 14 seedlings are pronged out, and the seedlings are pronged into the seedling falling bucket 91 and complete the second group of seedling throwing through the guide pipe 93. When the seedling prongs 842 rotate for the third 120°, the corresponding 3, 6, 9, 12, and 15 seedlings are pronged out, and the seedlings are pronged into the seedling falling bucket 91 and complete the third group of seedling throwing through the guide pipe 93.

[0088] On the basis of the above-mentioned embodiments, in another embodiment of the present application, the number of seedling falling buckets 91 is 1 / 3 of the number of rows of pot body blanket seedlings 2. Each seedling falling bucket 91 corresponds to 3 seedlings.

[0089] As Figure 13 shown is an initial seedling positioning and strip cutting station. After the driving motor 101 rotates clockwise, the seedling pushing cam 412 on the power shaft 105 contacts the cam contact piece 413, drives the seedling pushing power shaft 411 to move, thereby driving the connecting rod piece 415 to move, the movement of the connecting rod piece 415 drives the ratchet connecting piece 416 to move, thereby driving the conveying belt driving shaft 42 to move, the conveying belt 43 moves, thereby driving the pot body blanket seedlings 2 to move forward.

[0090] When the seedling pushing action is performed, the seedling positioning baffle 841 moves exactly in the same horizontal line as the seedlings, which is used to limit the pushing distance of the pot body blanket seedlings 2 and assist in realizing accurate positioning of the pot body blanket seedlings 2. At the same time when the seedling pushing action is performed, the cutting blade 571 cuts the pot body blanket seedlings 2, and the movement direction of the cutting assembly 57 is opposite to the movement direction of the driving motor 101. After the seedling pushing action is completed, the cutting station is entered.

[0091] As Figure 14 shown is a cutting station. After the driving motor 101 rotates clockwise, the cutting cam 66 on the power shaft 105 contacts the cutting connecting rod 64, and the upper and lower cutting assembly 62 moves upward to cut the blanket part of the pot body blanket seedlings 2. The seedling pushing cam 412 and the cutting cam 66 have a certain phase angle, thereby ensuring that after the seedling pushing action is completed, the upper and lower cutting assembly 62 starts cutting. After the cutting action is completed, the seedling separating action starts.

[0092] As Figure 15 The seedling falling position is shown. After the driving motor 101 rotates clockwise, power is transmitted to make the cutting assembly 57 rotate counterclockwise, and the power is transmitted to the batch seedling falling movement assembly 8 through the seedling falling power transmission assembly 82 and the seedling falling power reversing assembly 81. The batch seedling falling movement assembly 8 rotates clockwise, which is the same as the rotation direction of the driving motor 101. The pot body blanket seedlings 2 at the seedling fixing block 71 are sequentially grouped and pushed into the seedling bucket 91 under the action of the seedling falling fork 842, and the seedling throwing is completed.

[0093] The above is only the preferred embodiment of the present application, it should be noted that for those skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
