Description

Technical Field

[0001] The utility model relates to the technical field of hole-opening devices, in particular to a hole-opening device for fertilizing sand melons. Background Art

[0002] Planting sand melons requires pressing small sand and gravel on the land. This can reduce water evaporation during the day. At night, the water vapor condenses into water when it cools down and seeps through the sand and gravel. The pressed sand land can store water, retain moisture and keep warm, increase nutrition for crops, avoid water and wind erosion, and reduce soil and water loss.

[0003] In the existing planting process of pressed sand melon, it is necessary to first dig a hole in the ground, and then spread a certain amount of fertilizer into one or both sides of the hole, and then transplant the melon seedlings on the other side or in the middle of the hole to avoid direct contact between the fertilizer and the pressed sand melon seedlings and cause burning of the seedlings. In addition, the hole needs to be dug longer, but this hole-digging and fertilizing method is labor-intensive and time-consuming, and the planting efficiency is low. Therefore, a method is now adopted in which fertilizer is spread in the dug hole, and then a small hole is made to immediately put the melon seedling into the small hole to separate the melon seedling and the fertilizer, and then cover with soil. This technology is faster and more convenient to operate, and solves the problems of labor-intensive and time-consuming, low efficiency, etc. in the existing planting process.

[0004] Based on this, a hole-making device for fertilizing sand melons is now provided, which can eliminate the drawbacks of the prior art. Utility Model Content

The hole-making component includes a drill bit 6 and a threaded rod 11. The upper surface of the fixed seat 1 is threadedly connected to the threaded rod 11, and the lower surface of the threaded rod 11 is fixedly connected to the drill bit 6. The end of the threaded rod 11 away from the drill bit 6 is rotatably connected to a fixed plate 8 through a bearing. The side wall of the fixed plate 8 away from the threaded rod 11 is fixedly connected to a telescopic rod 2. The end of the telescopic rod 2 away from the fixed plate 8 is provided with a telescopic cylinder 3, and the adjustment component is provided at the connection between the telescopic rod 2 and the telescopic cylinder 3. When it is necessary to drill a hole, first place the fixing seat 1 at the hole drilling location, the user steps on the pedal 5 to facilitate the fixing device, holds the handle 4 and presses it downward, the handle 4 drives the telescopic rod 2 and the telescopic cylinder 3 to be pressed down, the telescopic rod 2 drives the threaded rod 11 to descend, and since the threaded rod 11 is a non-self-locking thread, the threaded rod 11 rotates simultaneously during the descent process, the threaded rod 11 drives the drill bit 6 to rotate, and the hole drilling process is time-saving and labor-saving, and there is no need to turn over the soil to drill a hole, and the hole drilling is faster and more convenient.

[0028] In one embodiment, Figure 4 As shown, the thread lead angle of the threaded rod 11 is greater than the equivalent friction angle of the screw pair formed by the threaded rod 11 and the fixing seat 1. The thread of the threaded rod 11 is not self-locking.

[0029] In one embodiment, Figure 3 and Figure 4 As shown, a damping spring 12 is fixedly connected between the fixing plate 8 and the fixing seat 1. The damping spring 12 drives the fixing plate 8 to reset.

[0030] In one embodiment, Figure 5As shown, four slider grooves 13 are provided on the upper surface of the fixing seat 1, and sliders 10 are slidably connected to the inner side walls of the four slider grooves 13. The side wall of the slider 10 located outside the slider groove 13 is rotatably connected to the connecting rod 9 through a pin, and the end of the connecting rod 9 away from the slider 10 is rotatably connected to the fixing plate 8 through a pin. When the telescopic rod 2 drives the fixing plate 8 to press down, the slider 10 slides in the slider groove 13 through the cooperation of the connecting rod 9 and the slider 10, and the fixing plate 8 is radially limited to prevent the fixing plate 8 from rotating during the descent of the telescopic rod 2, so that the damping spring 12 is twisted.

[0031] In one embodiment, Figure 4 As shown, the cross section of the slider 10 is T-shaped, which prevents the slider 10 from leaving the slider groove 13.

[0032] In one embodiment, Figure 2 and Figure 3 As shown, the adjustment assembly includes a threaded sleeve 7, the telescopic rod 2 is slidably connected to the inner wall of the telescopic cylinder 3, the telescopic cylinder 3 is provided with a thread at one end close to the telescopic rod 2, the telescopic cylinder 3 is threadedly connected to the threaded sleeve 7, and there is a pre-tightening force between the threaded sleeve 7 and the telescopic rod 2. By rotating the threaded sleeve 7, the threaded connection with the telescopic cylinder 3 is released, and then the telescopic rod 2 is pulled out of the telescopic cylinder 3, and then the threaded sleeve 7 is screwed back to complete the fixation of the telescopic rod 2 and the telescopic cylinder 3, the height of the device can be adjusted according to the height of the user, which is more convenient for the user to use.

[0033] Example 2

[0034] In one embodiment, Figure 2 As shown, a pedal 5 is fixedly connected to the side wall of the fixing seat 1. The user steps on the pedal 5 to facilitate the fixing device.

[0035] In one embodiment, Figure 1 and Figure 2 As shown, one end of the telescopic cylinder 3 away from the telescopic rod 2 is fixedly connected to a handle 4, and a rubber grip is provided on the side wall of the handle 4, so that the user is more comfortable when using the device.

The user steps on the pedal 5 to facilitate the fixing device, holds the handle 4 and presses it downward. The handle 4 drives the telescopic rod 2 and the telescopic cylinder 3 to be pressed downward, and the telescopic rod 2 drives the threaded rod 11 to descend. Since the threaded rod 11 is a non-self-locking thread, the threaded rod 11 rotates simultaneously during the descent process. The threaded rod 11 drives the drill bit 6 to rotate, and the soil in the pit is rotated to open a small hole, which saves time and effort, is quick and convenient.

[0037] The fixing plate 8 is driven to reset by the damping spring 12;

[0038] When the telescopic rod 2 drives the fixed plate 8 to press downward, the slider 10 slides in the slider groove 13 through the cooperation of the connecting rod 9 and the slider 10, and the fixed plate 8 is radially limited to prevent the fixed plate 8 from rotating during the descent of the telescopic rod 2, which causes the damping spring 12 to twist;

[0039] By rotating the threaded sleeve 7 to release the threaded connection with the telescopic cylinder 3, the telescopic rod 2 is pulled out of the telescopic cylinder 3, and then the threaded sleeve 7 is screwed back to complete the fixation of the telescopic rod 2 and the telescopic cylinder 3. The height of the device can be adjusted according to the height of the user, which is more convenient for the user to use.
