[0007] Furthermore, the end of the second connecting rod that connects to the rocker arm has several hinge holes.

[0008] Furthermore, a drive assembly for driving the second rotating shaft to rotate is also provided.

[0009] Furthermore, the drive assembly includes a first mounting plate fixed to the lower end of the frame, a motor mounted on the first mounting plate, a third sprocket mounted on the motor output shaft, a second mounting plate fixed to the lower end of the frame, a third rotating shaft rotatably mounted on the second mounting plate, a fourth sprocket and a fifth sprocket respectively mounted on the third rotating shaft, a sixth sprocket mounted on the second rotating shaft, a second drive chain for connecting the third sprocket and the fourth sprocket, and a third drive chain for connecting the fifth sprocket and the sixth sprocket.

[0015] During operation, the drive assembly rotates the second shaft, which in turn drives the first shaft to rotate via a first sprocket, a second sprocket, and a first transmission chain. The rotation of the first shaft causes two first connecting rods mounted at both ends to rotate in a circular motion. The rocker arm, driven by the first and second connecting rods, oscillates periodically, causing the digging shovel to swing up and down, thus achieving the digging and drilling operation. Because the two first connecting rods on both sides have different installation angles and different lengths, the rotation of the first shaft causes the two digging shovels to swing alternately, working together to complete the drilling of a transplanting hole. This invention has a simple structure, low cost, and can achieve automatic drilling with high work efficiency. Attached Figure Description

Detailed Implementation

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1

[0024] A type of hole punch for tobacco transplanting, such as Figure 1-5 As shown, the machine includes a frame 1, on which a crossbeam 2 is fixedly connected; a first rotating shaft 3 is rotatably mounted at both ends of the crossbeam 2 via bearing seats 4; a soil-shoveling mechanism is mounted at both ends of the first rotating shaft 3; a second rotating shaft 16 is rotatably mounted at the upper end of the frame 1; a first sprocket 13 and a second sprocket 14 are respectively mounted on the first rotating shaft 3 and the second rotating shaft 16; the first sprocket 13 and the second sprocket 14 are connected by a first transmission chain 15.

[0025] When the tobacco transplanting hole puncher is working, the drive assembly drives the second rotating shaft 16 to rotate, and drives the first rotating shaft 3 to rotate through the second sprocket 14, the first transmission chain 15, and the first sprocket 13. The rotation of the first rotating shaft 3 can drive the two sets of soil-shoveling mechanisms on both sides to swing up and down alternately. The two sets of soil-shoveling mechanisms work together to complete the hole punching operation of a transplanting hole, which improves work efficiency.

[0026] Specifically, each shoveling mechanism includes a rocker arm 7, a first connecting rod 6 connected at one end to the first rotating shaft 3, and a second connecting rod 8 hinged at one end to the frame 1; one end of the rocker arm 7 is hinged to one end of the second connecting rod 8, and the other end is equipped with a digging shovel 10; one end of the first connecting rod 6 is hinged to the rocker arm 7; the installation angles of the first connecting rods 6 of the two shoveling mechanisms are staggered, and the lengths of the rocker arms 7 of the two shoveling mechanisms are different.

[0027] The rotation of the first rotating shaft 3 drives the two first connecting rods 6 installed at both ends of the first rotating shaft to rotate in a circular motion. The rocker arm 7, driven by the first connecting rod 6 and the second connecting rod 8, oscillates periodically, thereby causing the digging shovel 10 to swing up and down, realizing the digging and drilling operation. Since the installation angles of the two first connecting rods 6 on both sides are different, and the lengths of the two rocker arms 7 are different, the rotation of the first rotating shaft 3 can drive the two digging shovels 10 to swing alternately. The two digging shovels 10 work together to complete the drilling operation of a transplanting hole.

[0028] Specifically, a mounting bracket 9 is detachably mounted on one end of the rocker arm 7; the digging shovel 10 is mounted on the mounting bracket 9; and an arc-shaped groove 19 for connecting the mounting bracket 9 is provided on one end of the rocker arm 7. Mounting the digging shovel 10 via the mounting bracket 9 facilitates replacement or maintenance of the digging shovel 10. The installation angle of the digging shovel 10 can be adjusted by providing the arc-shaped groove 19, thereby adjusting the drilling depth.

[0029] Specifically, the end of the second connecting rod 8 that connects to the rocker arm 7 has several hinge holes. By changing the hinge holes connecting the second connecting rod 8 and the rocker arm 7, the drilling depth can also be changed.

[0030] Specifically, a drive assembly for driving the second rotating shaft 16 to rotate is also provided.

[0031] Specifically, the drive assembly includes a first mounting plate 21 fixed to the lower end of the frame 1, a motor 22 mounted on the first mounting plate 21, a third sprocket 23 mounted on the output shaft of the motor 22, a second mounting plate 27 fixed to the lower end of the frame 1, a third rotating shaft 26 rotatably mounted on the second mounting plate 27, a fourth sprocket 24 and a fifth sprocket 25 respectively mounted on the third rotating shaft 26, a sixth sprocket 28 mounted on the second rotating shaft 16, a second transmission chain 29 for connecting the third sprocket 23 and the fourth sprocket 24, and a third transmission chain 30 for connecting the fifth sprocket 25 and the sixth sprocket 28.

[0032] During operation, motor 22 drives the third sprocket 23 to rotate. The third sprocket 23 drives the fourth sprocket 24 to rotate via the second transmission chain 29. The fourth sprocket 24 drives the third shaft 26 and the fifth sprocket 25 to rotate. The rotation of the fifth sprocket 25 drives the sixth sprocket 28 to rotate via the third transmission chain 30. The rotation of the sixth sprocket 28 pulls the second shaft 16 to rotate. In this embodiment, the drive assembly not only drives the second shaft 16 to rotate, but also achieves multi-stage speed reduction by reasonably setting the number of teeth on the multiple sprockets.

[0033] In another embodiment, all sprockets can be replaced with pulleys, and all drive chains can be replaced with drive belts.

[0034] Specifically, the front end of the frame 1 is equipped with a connecting part 20 for connecting to a traction machine. The traction machine can be connected to the connecting part 20, thereby driving the entire tobacco transplanting hole punch forward.

[0035] In another embodiment, the connecting part 20 can be replaced with a handle, and the entire tobacco transplanting punch can be moved forward by manually holding the handle.

[0036] Specifically, support legs are installed at the lower end of the frame 1, and walking wheels 17 are installed at the lower end of the support legs. If a traction machine is installed, two sets of support legs or four sets can be installed. If a handle is installed and manual pushing is required, four sets of support legs are required.

[0037] Specifically, the support leg includes a support rod 18 fixed to the side wall of the frame 1, a sleeve rod 11 fixed to the support rod 18, and an insert rod 12 inserted into the sleeve rod 11; the traveling wheel 17 is installed at the lower end of the insert rod 12. By adjusting the height of the insert rod 12 inserted into the sleeve rod 11, the height of the frame 1 from the ground can be adjusted, thereby adjusting the drilling depth. In this embodiment, bolts are used to tighten the insert rod 14. In another embodiment, several holes can be opened on the insert rod 14, and bolts can be used to connect them.

[0038] Specifically, in order to facilitate the disassembly and assembly of the first rotating shaft 3, a vertical plate 5 is fixedly connected to the upper end of the crossbeam 2; the bearing seat 4 is detachably installed on the vertical plate 5; and an opening slot for the first rotating shaft 3 to pass through is provided on the vertical plate 5.

[0039] The working principle of this utility model:

[0040] The tobacco transplanter can be pulled forward using a traction device or manually pushed. When motor 22 is turned on, it drives the third sprocket 23 to rotate. The third sprocket 23 drives the fourth sprocket 24 via the second transmission chain 29. The fourth sprocket 24 drives the third shaft 26 and the fifth sprocket 25 to rotate. The fifth sprocket 25 drives the sixth sprocket 28 via the third transmission chain 30. The sixth sprocket 28 then pulls the second shaft 16 to rotate. The second shaft 16 rotates, driving the first shaft 3 to rotate via the first sprocket 13, the second sprocket 14, and the first transmission chain 15. The rotation of the first shaft 3 causes the two first connecting rods 6 installed at both ends of the first shaft to rotate in a circular motion. The rocker arm 7 oscillates periodically under the action of the first connecting rod 6 and the second connecting rod 8, causing the digging shovel 10 to swing up and down, thus achieving the digging and drilling operation. Since the installation angles of the two first connecting rods 6 on both sides are different, and the lengths of the two rocker arms 7 are different, the rotation of the first rotating shaft 3 can drive the two digging shovels 10 to swing alternately, and the two digging shovels 10 work together to complete the drilling operation of a transplanting hole.

[0041] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
