Description

Technical Field

[0001] This application relates to the field of cabbage breeding, and in particular to a rolling pit device for cabbage breeding planting holes. Background Technology

[0002] Seedling tray raising is an important method of crop breeding. It involves filling the holes in a crop seedling tray with soil or other substrate, then making holes in the soil to create planting holes. Crop seeds are then sown into the inner cavity of the tray to carry out crop breeding.

[0003] After the seedling trays are filled with soil, users will use tools such as chopsticks to make planting holes in the soil. The depth of the planting holes depends on the user's experience. Inconsistent planting hole depths can cause seeds to be buried at an improper depth, affecting germination. Therefore, a seedling planting hole rolling device is needed. This device can make holes in the soil of the seedling trays through a perforated structure, avoiding inconsistent planting hole depths that could lead to improper seed burial and ensuring normal and consistent germination of crops. Summary of the Invention

[0004] To address the existing technical problems, this application provides a rolling pit device for cabbage breeding and planting holes.

[0005] This application provides a cabbage breeding planting hole rolling device, which adopts the following technical solution: A cabbage breeding planting hole rolling device includes an operating table, a fixed frame is provided on the top of the operating table, a fixed bracket is fixedly connected to the top of the operating table, a slide is provided in the inner cavity of the fixed bracket, two symmetrical rollers are rotatably connected to both sides of the slide, limit grooves are provided on the front and back of the inner cavity of the fixed bracket, the rollers roll in the inner cavity of the limit groove, a fixed block is fixedly connected to the top of the slide, and a threaded rod is rotatably connected to the inner cavity of the fixed bracket, the threaded rod passing through... A fixing block is fixed and threadedly connected to the fixing block. A motor is fixedly installed on the right side of the fixing frame one by bolts. The output shaft of the motor passes through the inner cavity of the fixing frame one and is fixedly connected to the threaded rod. A fixing plate is provided at the bottom of the slide. A fixing frame two is connected to the bottom of the fixing plate. A pressing roller is rotatably connected to the inner cavity of the fixing frame two. Two longitudinal limiting rods are fixedly connected to the top of the fixing plate. The limiting rods pass through the slide and are slidably connected to the slide. A cylinder is fixedly installed on the top of the slide by bolts. The output end of the cylinder passes through the slide and is fixedly connected to the top of the fixing plate.

[0006] By adopting the above technical solution, the cabbage seedling tray is placed in the inner cavity of the fixed frame. The cylinder is activated, causing the pressing roller to move downwards and fit against the top of the cabbage seedling tray. At this time, the cone on the surface of the pressing roller will make holes in the soil. The motor is started, causing the slide to drive the pressing roller to move, so that the pressing roller rolls and makes holes on the top of the cabbage seedling tray. This avoids the seedlings from being buried at an improper depth due to inconsistent planting hole depth, thus ensuring the normal emergence of cabbage seedlings.

[0007] Preferably, the top of the second fixing frame is fixedly connected to two longitudinal fixing rods, which pass through the fixing plate and are slidably connected to the fixing plate.

[0008] Preferably, a spring is fitted on the surface of the fixing rod, the top of the spring is fixedly connected to the bottom of the fixing plate, and the bottom of the spring is fixedly connected to the top of the second fixing frame.

[0009] By adopting the above technical solution, and through the combined use of the fixing rod and spring, when the cylinder pushes the fixing plate and fixing frame to move downwards, the pressing roller will rebound, which avoids excessive downward pressure on the pressing roller and damage to the cabbage seedling tray, thus ensuring the safety of the soil hole opening in the cabbage seedling tray.

[0010] Preferably, the top of the fixing frame has two symmetrical openings, and the inner cavity of the fixing frame is fixedly connected with multiple transverse support rods.

[0011] Preferably, the inner cavity of the fixed frame is provided with a seedling tray, the slide is parallel to the fixed plate, and the pressing roller is located above the fixed frame.

[0012] Preferably, the top of the second fixing frame is inverted L-shaped, the second fixing frame slides at the bottom of the fixing plate, and the cylinder is located directly above the fixing plate.

[0013] Preferably, the surface of the pressing roller is provided with multiple rows of tapered rods, the end of the tapered rod away from the pressing roller is rounded, and the spacing between the tapered rods on the surface of the pressing roller is the same as the spacing between the seedling holes in the seedling tray.

[0014] In summary, this application includes at least one of the following beneficial technical effects: This invention involves placing a cabbage seedling tray inside a fixed frame, activating a cylinder to move a perforating roller downwards to fit against the top of the cabbage seedling tray. At this time, the conical rod on the surface of the perforating roller will create holes in the soil. Activating a motor causes the slide to move the perforating roller, allowing it to roll and create holes on the top of the cabbage seedling tray. This avoids uneven planting hole depths that could lead to improper seed burial and ensures normal germination of the cabbage.

[0015] This invention utilizes the combined use of a fixing rod and a spring. When the cylinder pushes the fixing plate and fixing frame downwards, the pressing roller will rebound, preventing excessive downward pressure from damaging the cabbage seedling tray and ensuring the safety of the soil holes in the cabbage seedling tray.

The surface of the pressing roller 12 is provided with multiple rows of conical rods. The end of the conical rod away from the pressing roller 12 is rounded. The spacing between the conical rods on the surface of the pressing roller 12 is the same as the spacing between the seedling holes in the seedling tray. Two longitudinal limiting rods 13 are fixedly connected to the top of the fixed plate 10. The limiting rods 13 pass through the slide 4 and are slidably connected to the slide 4. The top of the slide 4 is fixedly installed with a cylinder 14 by bolts. The output end of the cylinder 14 passes through the slide 4 and is fixedly connected to the top of the fixed plate 10. Example 2

[0023] Combination Figure 3 and Figure 4 The top of the second fixing frame 11 is fixedly connected to two longitudinal fixing rods 15. The fixing rods 15 pass through the fixing plate 10 and are slidably connected to the fixing plate 10. A spring 16 is sleeved on the surface of the fixing rod 15.

Through the limiting groove 6, the slide 4 drives the pressing roller 12 to move through the fixed plate 10 and the second fixed frame 11, causing the pressing roller 12 to roll and open holes on the top of the cabbage seedling tray. This avoids uneven planting hole depths that could lead to improper seed burial, ensuring normal germination of the cabbage. When the cylinder 14 pushes the fixed plate 10 and the second fixed frame 11 downwards, the pressing roller 12 will rebound, preventing excessive downward pressure from damaging the cabbage seedling tray and ensuring the safety of the soil opening in the cabbage seedling tray.

[0025] In summary, this crop seedling planting hole rolling device works by placing the crop seedling tray inside the fixed frame 2, activating the cylinder 14 to move the pressing roller 12 downwards to fit against the top of the crop seedling tray. At this time, the cone on the surface of the pressing roller 12 will open holes in the soil. Activating the motor 9 will cause the slide 4 to drive the pressing roller 12 to move, so that the pressing roller 12 rolls and opens holes on the top of the seedling tray. This avoids uneven planting hole depths that could lead to improper seed burial and ensures normal crop germination.
