Shoveling mechanisms are installed at both ends of the second rotating shaft 14. A shifting mechanism is installed at the upper end of the frame 1. The transmission ratios of the two sets of first sprockets 3 and second sprockets 15 are different.
[0026] When the transplanting distance needs to be adjusted, the control shift mechanism cooperates with the corresponding first sprocket 3, the first sprocket 3 drives the corresponding second sprocket 15 to rotate through the transmission chain 16, thereby driving the second rotating shaft 14 to rotate, driving the shovel mechanism at both ends of the second rotating shaft 14 to alternately shovel, thereby completing the punching operation of the transplanting hole.
[0027] Specifically, the first sprocket 3 is movably installed on the first rotating shaft 2; the first rotating shaft 2 is provided with a circlip 9 at one end away from the first sprocket 3; the shift mechanism comprises a moving sleeve 4 and a transmission part 5 fixed at both ends of the moving sleeve 4; the two first sprockets 3 are provided with grooves 6 on one side close to each other; the inner wall of the groove 6 and the outer wall of the transmission part 5 are provided with teeth matched with each other; the middle part of the outer wall of the first rotating shaft 2 is provided with a sliding groove; the inner wall of the moving sleeve 4 is connected with a sliding block matched with the sliding groove. When punching, the transmission part 5 at one end of the moving sleeve 4 cooperates with one of the first sprockets 3, the first rotating shaft 2 rotates, drives the moving sleeve 4 to rotate, and under the action of the teeth matched with each other of the transmission part 5 and the groove 6, the rotation of the first rotating shaft 2 is transmitted to the first sprocket 3, and then the second sprocket 15 is driven to rotate through the transmission chain 16.
[0028] Specifically, the upper part of the rack 1 is movably provided with a sliding shaft 12, and the sliding shaft 12 is provided with a lever 11; the two sides of the moving sleeve 4 are provided with limit rings 401; one end of the lever 11 is fixedly connected with a semi-annular pushing part 1101; a gap is provided between the pushing part 1101 and the middle part of the moving sleeve 4. When shifting, the sliding shaft 12 is controlled to move forward and backward, thereby driving the lever 11 to move, the lever 11 moves to drive the moving sleeve 4 to move, until the moving sleeve 4 is pushed into the groove 6. When working, the first rotating shaft 2 rotates to drive the moving sleeve 4 to rotate, and since there is a gap between the moving sleeve 4 and the pushing part 1101, the lever 11 does not interfere with the rotation of the moving sleeve 4.
[0029] Specifically, in order to facilitate the disassembly and assembly of the first rotating shaft 2 and the second rotating shaft 14, the upper part of the first cross beam 32 and the second cross beam 33 is respectively fixedly connected with a first vertical plate 7 and a second vertical plate 17; the first bearing seat 8 and the second bearing seat 18 are respectively installed on the first vertical plate 7 and the second vertical plate 17; the first vertical plate 7 and the second vertical plate 17 are respectively provided with an open slot 10 for penetrating the first rotating shaft 2 and the second rotating shaft 14.
[0030] Specifically, one side of the two first vertical plates 7 is fixedly connected with a sliding sleeve 13 slidably connected with the sliding shaft 12; one side of the rack 1 is fixedly connected with a supporting plate 28; the upper part of the supporting plate 28 is hingedly connected with a shift lever 29; one end of the shift lever 29 is provided with a strip-shaped slot 30; the lower end of the sliding shaft 12 is fixedly connected with a protruding column penetrating the strip-shaped slot 30.

The rotation of the second rotating shaft 14 can drive the two first connecting rods 19 installed at both ends of the second rotating shaft 14 to rotate in a circle respectively, and the rocker 21 is periodically swung under the driving of the first connecting rod 19 and the action of the second connecting rod 20, so that the digging shovel 25 is swung up and down to realize the digging and punching operation. Since the installation angles of the two first connecting rods 19 on both sides are different, and the lengths of the two rockers 21 are different, the two digging shovels 25 can be staggered and swung under the rotation of the second rotating shaft 14, and the punching operation of one transplanting hole is completed by the two digging shovels 25 in cooperation.
[0032] Specifically, in order to facilitate the adjustment of the punching depth, an arc-shaped slot 27 for connecting the mounting rack 24 is formed at one end of the rocker 21; and a plurality of hinged holes are formed at the end of the second connecting rod 20 connected with the rocker 21. By adjusting the positions of the hinged holes of the second connecting rod 20 and the rocker 21, and the installation positions of the arc-shaped slot 27 of the mounting rack 24 and the rocker 21, the installation angle of the rocker 21 can be adjusted, so that the punching depth can be adjusted.
[0033] Specifically, one end of the first rotating shaft 2 is installed with a driving sprocket 34; and the driving sprocket 34 is connected with a driving assembly through a driving transmission chain. The driving assembly can be a motor installed on the frame 1 and a sprocket installed on the motor; or can be a sprocket capable of rotating installed on a tractor and a driving device capable of driving the sprocket to rotate.

[0035] In another embodiment, the connecting part 31 can be replaced by a handle, and the whole adjustable-plant-spacing crop transplanting and punching machine is dragged to move forward by means of manpower holding the handle.
[0036] Specifically, the support leg comprises a support rod 22 fixed to the side wall of the frame 1, a sleeve rod 23 fixed to the support rod 22, and a plug rod 26 inserted into the sleeve rod 23; the walking wheel is mounted at the lower end of the plug rod 26. By adjusting the height of the plug rod 26 inserted into the sleeve rod 23, the ground clearance of the frame 1 can be adjusted, so that the punching depth can be adjusted. In the embodiment, the plug rod 26 is tightened by bolts. In another embodiment, a plurality of holes can be formed on the plug rod 26, and the plug rod 26 is connected by bolts.
[0037] In another embodiment, all the chain wheels can be replaced by pulleys, and the transmission chain can be replaced by a synchronous belt.
[0038] The working principle of the utility model:
[0039] The adjustable-plant-spacing crop transplanting punch is pulled forward by the traction device, or is manually pushed forward. The driving assembly drives the driving chain wheel 34 to rotate, thereby driving the first rotating shaft 2 to rotate. The first rotating shaft 2 drives the moving sleeve 4 to rotate, and under the action of the tooth-shaped mutual cooperation of the transmission part 5 and the groove 6, the rotation of the first rotating shaft 2 is transmitted to the first chain wheel 3, and then the second chain wheel 15 is driven to rotate by the transmission chain 16, thereby driving the second rotating shaft 14 to rotate. The rotation of the second rotating shaft 14 can drive the two first connecting rods 19 installed at both ends of the second rotating shaft 14 to rotate circumferentially, respectively, and the rocker 21 is periodically swung under the action of the first connecting rod 19 and the second connecting rod 20, thereby making the earth scoop 25 swing up and down to realize the earth digging and punching operation. Since the installation angles of the two first connecting rods 19 on both sides are different, and the lengths of the two rockers 21 are different, the second rotating shaft 14 can drive the two earth scoops 25 to swing alternately when the second rotating shaft 14 rotates, and the two earth scoops 25 cooperate to complete the punching operation of one transplanting hole. When shifting gears, one end of the shift lever 29 is rotated, the shift lever 29 rotates around the hinge shaft, the other end of the shift lever 29 is rotated, and under the action of the strip-shaped groove 30 and the sliding sleeve 13, the sliding shaft 12 drives the shift rod 11 to move. The movement of the shift rod 11 can drive the movement of the moving sleeve 4, until the moving sleeve 4 is pushed into the groove 6, thereby completing the gear shifting.
