Technical Field

[0001] This utility model belongs to the field of cotton planting technology, and in particular relates to a cotton planting hole punch with adjustable punching depth. Background Technology

[0002] Cotton is one of the world's most important crops, with high yields and low production costs, making cotton products relatively inexpensive. Cotton fibers can be made into a variety of fabrics, from lightweight and transparent voile to thick canvas and velvet, suitable for making various types of clothing, furniture fabrics, and industrial textiles. In current cotton cultivation, a hole punch is used to make holes in the soil, and then treated seeds are added into the soil holes for cotton planting.

[0003] The soil perforators used in cotton cultivation typically use a motor to drive a screw rod to punch holes in the soil. The screw rod is usually exposed, making it difficult to standardize the drilling depth. In order to improve the adaptability of the perforator's drilling depth to different batches of cotton, there is a need for a cotton perforator with adjustable drilling depth. This would allow for adjustment of the drilling depth and standardization of the drilling depth, thereby improving the accuracy and adaptability of the perforator. Utility Model Content

[0025] In the following description, embodiments of the adjustable-depth perforation perforator for cotton planting according to the present invention will be described with reference to the accompanying drawings.

[0026] Example 1:

[0027] Figure 1-4 This invention illustrates an adjustable-depth cotton planting hole punch according to an embodiment of the present invention. It includes a motor 1; a rotating rod 2 is fixedly connected to the output shaft of the motor 1 via a flange; a spiral drill rod 3 is welded to the bottom end of the rotating rod 2; an externally threaded sleeve 4 is fixedly mounted on the surface of the motor 1; an internally threaded ring 5 is threadedly connected to the surface of the externally threaded sleeve 4; a sleeve 6 is rotatably connected to the bottom of the internally threaded ring 5; two symmetrically arranged connecting rods 7 are welded to the surface of the sleeve 6; a limiting sleeve 8 is welded to the surface of the connecting rods 7; a rubber washer 9 is attached to the bottom of the limiting sleeve 8. The washer 9 protects the bottom of the limiting sleeve 8, preventing it from directly contacting the soil and corroding, thus improving the protection of the limiting sleeve 8. The sleeve 6... The sleeve 6 has a threaded bolt rod 10 installed on its surface. The end of the bolt rod 10 penetrates into the inner cavity of the sleeve 6 and abuts against the external threaded sleeve 4. An elastic washer 11 is fitted on the surface of the bolt rod 10. The elastic washer 11 fits against the sleeve 6. The elastic washer 11 increases the friction on the surface of the bolt rod 10, preventing the bolt rod 10 from loosening and coming off due to external vibration, thereby improving the stability of the bolt rod 10 position. The surface of the internal threaded ring 5 is frosted with a frosted surface 12. The frosted surface 12 increases the friction on the surface of the internal threaded ring 5, preventing the internal threaded ring 5 from slipping when rotated by hand. Two symmetrically arranged sliders 14 are welded to the surface of the external threaded sleeve 4. The inner wall of the sleeve 6 has a groove 15 that matches the sliders 14.

[0028] Example 2:

[0029] Figure 1-4 This invention illustrates an adjustable-depth cotton planting hole punch according to an embodiment of the present invention. It includes a motor 1; a rotating rod 2 is fixedly connected to the output shaft of the motor 1 via a flange; a spiral drill rod 3 is welded to the bottom end of the rotating rod 2; an externally threaded sleeve 4 is fixedly mounted on the surface of the motor 1; an internally threaded ring 5 is threadedly connected to the surface of the externally threaded sleeve 4; a sleeve 6 is rotatably connected to the bottom of the internally threaded ring 5; two symmetrically arranged connecting rods 7 are welded to the surface of the sleeve 6; a limit sleeve 8 is welded to the surface of the connecting rods 7; a bolt rod 10 is threadedly mounted on the surface of the sleeve 6; and two symmetrically arranged connecting rods 7 are welded to the surface of the externally threaded sleeve 4. The inner wall of the sleeve 6 is provided with a sliding groove 15 that matches the slider 14. The surfaces of the two connecting rods 7 are welded with a reinforcing ring 13. By setting the reinforcing ring 13, the surface of the connecting rod 7 is welded and reinforced, which improves the overall integrity and stability of the connecting rod 7 structure, and thus improves the stability of the limiting sleeve 8 on the outside of the spiral drill rod 3. The surface of the handle of the motor 1 is covered with a handle cover 16. By setting the handle cover 16, the handle of the motor 1 is protected, which prevents the hand from slipping when holding the handle directly, and thus improves the stability of holding the motor 1 during operation.

[0030] Working Principle: When using this utility model, the user moves the internal threaded ring 5 vertically on the surface of the external threaded sleeve 4 by rotating it. At this time, under the limiting action of the slider 14 and the groove 15, the internal threaded ring 5 drives the sleeve 6 to move vertically outside the external threaded sleeve 4. Then, the sleeve 6 drives the connecting rod 7 to move vertically. Subsequently, the connecting rod 7 drives the limiting sleeve 8 to change the height outside the spiral drill rod 3. Then, by rotating the bolt rod 10 to tighten it against the external threaded sleeve 4, the position of the sleeve 6 outside the external threaded sleeve 4 is locked, thereby fixing the height of the limiting sleeve 8 outside the spiral drill rod 3. Then, the motor 1 drives the rotating rod 2 to rotate, so that the rotating rod 2 drives the spiral drill rod 3 to drill holes in the soil. During this process, the drilling depth of the spiral drill rod 3 is limited by the limiting sleeve 8, realizing the adjustment of the drilling depth of the drill and standardizing the drilling depth, thereby improving the accuracy and adaptability of the drill.

[0031] In summary, this adjustable-depth cotton planting punch achieves vertical adjustment of the punching depth by rotating the inner threaded ring 5 and moving it vertically on the surface of the outer threaded sleeve 4. Under the limiting action of the slider 14 and the groove 15, the sleeve 6 drives the connecting rod 7 to move vertically. Subsequently, the connecting rod 7 changes the height of the limiting sleeve 8 outside the spiral drill rod 3, thus achieving adjustment of the punching depth and standardizing the punching depth, thereby improving the accuracy and adaptability of the punch.
