Detailed Implementation

[0022] The following will refer to the appendices in the embodiments of the present invention. Figure 1-7 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1, see appendix Figure 1 and 2 As shown:

[0024] A tray pressing device for cabbage seedling cultivation includes a frame 2 and a pressing device 1. The frame 2 includes a first frame 21 fixedly connected by a connecting frame 23 and a second frame 22 hinged together. A hydraulic device 3 is provided on the connecting frame 23 and the second frame 22, and the hydraulic device 3 drives the connecting frame 23 to rotate around the hinged shaft. The frame 2 is connected to the tractor traction unit through a trapezoidal frame 4. The pressing device 1 is rotatably mounted on the frame 2 and includes a hollow roller 11. End cap supports 12 are fixed on the left and right sides of the roller 11, and end caps 13 are bolted to the end cap supports 12. A plurality of pressing heads 14 are evenly distributed on the outer surface of the roller 11.

[0025] The tractor-pulled cabbage seedling tray pressing device operates by driving the hydraulic device 3 to adjust the connecting frame 23 so that the hinged shaft rotates. This causes the first frame 21 to swing up and down with the connecting frame 23, thereby adjusting whether the roller 11 is off the ground or in contact with the ground. When pressing the seedling trays, after the hydraulic device 3 drives the roller 11 to contact the ground, the tractor-pulled cabbage seedling tray pressing device moves forward. As the roller 11 rotates and moves forward, multiple pressing heads 14 evenly distributed on the roller 11 press out evenly distributed seedling trays on the ground. These seedling trays are used for transplanting cabbage seedlings. This structure mechanizes the digging of seedling trays, thus replacing manual labor.

[0026] Example 2, see appendix Figure 2-7 As shown:

[0027] End cap support 12 includes a left end cap support 121 and a right end cap support 122 with the same structure; end cap 13 includes a left end cap 131 and a right end cap 132 with the same structure. Preferably, the left end cap support 121 is a cross-shaped frame with a first shaft hole 1211 on its shaft portion and four screw holes on one side of its contact portion with the roller 11; the left end cap 131 has a second shaft hole 1311 on its shaft portion that matches the first shaft hole 1211 of the left end cap support 121, and a bolt through hole matching the four screw holes of the left end cap support 121 is opened near its edge.

[0028] The detachable end cap 13 allows for the filling of the hollow roller 11 with a suitable medium, such as locally available soil or other materials, to increase the counterweight of the pressing device 1 and assist in the pressing of the pit. The conical pressing head 14 is superior to other structures, as it can smoothly press the pit into a conical shape, making the pit less prone to collapse and more stable, further reducing the time required for manual repair.

[0029] The pressure head 14 is a conical body; it is welded to the surface of the roller 11, and its sharp end is rounded to avoid scratching the operator.

[0030] The first frame 21 includes L-shaped rods 211 symmetrically arranged on the left and right. The right side of the horizontal bar of the L-shaped rod 211 has a through hole for installing an adjusting spring bolt 212. The lower part of the vertical bar of the L-shaped rod 211 has a connecting block for installing a U-shaped clip 219, and the middle of the vertical bar of the L-shaped rod 211 has a first connecting lug 216. The first connecting lug 216 is hinged to one end of a diagonal rod 214. The other end of the diagonal rod 214 has a through hole for installing a bearing 218, and the middle of the diagonal rod 214 has a second connecting lug 217. The second connecting ear 217 is hinged to the lower end of the adjusting spring bolt 212; the bearings 218 are a pair, one at the rear and one at the front, which is rotatably connected to one end of the first connecting shaft 215, and the other bearing 218 is installed in the first shaft hole 1211 where the end cover support 12 is located, and is rotatably connected to the other end of the first connecting shaft 215; a spring 213 is fitted onto the adjusting spring bolt 212 and fixed to the L-shaped rod 211 and the inclined rod 214 by the nut on which it is located.

[0031] The adjusting spring bolt 212 is used to adjust the pressure between the pressing device 1 and the ground, and can be used to finely adjust the contact height with the ground. When the pressing head 14 of the pressing device 1 encounters a hard material on the ground, the spring 213 is compressed, and the adjusting spring bolt 212 moves upward to release excessive stress, thereby protecting the sharp part of the pressing head 14 and avoiding further damage to the pressing device of the cabbage seedling tray.

[0032] The connecting frame 23 includes a U-shaped frame 231, which is composed of a horizontal beam and a pair of vertical beams set at both ends of the horizontal beam. The upper part of the connection between the vertical beam and the horizontal beam is provided with a third connecting ear 232 for connecting the hydraulic device 3. The first frame 21 is connected to the connecting block at the lower part of the vertical rod of the L-shaped rod 211 through a U-shaped clip 219.

[0033] The second frame 22 includes a square frame 221, which is formed by a front beam, a rear beam, a left beam, and a right beam. The left and right beams are symmetrically provided with a fourth connecting ear 222 and a fifth connecting ear 223 at both ends. The fourth connecting ear 222 is hinged to the open end of the U-shaped frame 231. A pair of sixth connecting ears 224 are provided in the middle of the front side of the front beam. The sixth connecting ears 224 cooperate with and are hinged to the connecting parts of the tractor.

[0034] The trapezoidal frame 4 includes an inverted U-shaped frame 41. The opening of the inverted U-shaped frame 41 is fixedly connected to the middle part of the front beam of the square frame 221. The length of the opening of the inverted U-shaped frame 41 is greater than the length of the opposite opening. A seventh connecting ear 42 is provided on the frame at the opposite opening. The seventh connecting ear 42 cooperates with and is hinged to the connecting part of the tractor.

[0035] The hydraulic device 3 includes a left hydraulic device 32 and a right hydraulic device 31 with the same structure; the left hydraulic device 32 includes a hydraulic cylinder 321, which is movably connected to a hydraulic rod 322, and a hydraulic pipe 323 is provided on the hydraulic cylinder 321; the output end of the hydraulic rod 322 is hinged to the third connecting lug 232; the front end of the hydraulic cylinder 321 is hinged to the fifth connecting lug 223.

[0036] The hydraulic pipe 323 in the above structure is connected to the hydraulic output line of the tractor to drive the hydraulic rod 322 to move within the hydraulic cylinder 321. This causes the connecting frame 23 to rotate along the axis at the hinge between the fourth connecting ear 222 and the U-shaped frame 231, thereby causing the pressing device 1 installed on the first frame 21 to detach from or contact the ground, facilitating the operation of raising or lowering the pressing device 1 relative to the ground. A pair of sixth connecting ears 224 and a seventh connecting ear 42 form a triangular stable connection surface with the connecting part of the tractor to ensure the structural stability of the pressing device for cabbage seedling trays.

[0037] The tractor is driven into the cabbage planting area. The hydraulic system of the tractor is started, and the hydraulic rod 322 extends out from the hydraulic cylinder 321. This causes the connecting frame 23 to rotate along the shaft at the hinge between the fourth connecting ear 222 and the U-shaped frame 231, so that the pressing device 1 installed on the first frame 21 contacts the ground. After further adjusting the depth of the pressing head 14 where the pressing device 1 is located into the ground, the tractor is driven to move. The roller 11 rotates relative to the ground. Under the action of the pressing head 14, evenly distributed pressing holes are formed on the ground for the transplanting of cabbage seedlings.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
