Description

Technical Field

[0001] This utility model belongs to the field of sowing technology, and in particular relates to a seed planter for breeding plots. Background Technology

[0002] When sowing seeds in holes, a suitable depth of holes is beneficial for seed germination and growth. Currently, most breeding plots use the traditional manual hole-sowing method, which involves manually digging holes with tools such as shovels and picks. However, it is difficult to control the digging depth during actual digging. If the seeds are buried too shallowly, they will be exposed and damaged by birds pecking at them or rainwater washing away. If the seeds are buried too deep, they will not be able to emerge smoothly. Taking alfalfa hole sowing as an example, the ideal sowing depth is 1-2 cm, but when digging with tools such as shovels and picks, the actual depth often reaches 5-7 cm, causing the seeds to consume more energy to break through the soil and affecting the germination rate. Utility Model Content

Both the inner and outer walls of the inner sleeve are coated with a nano-coating. A scraper is fixed to the inner wall of the outer edge, and the scraper is slidably connected to the outer wall of the inner sleeve with the nano-coating. The spiral cutter head is located in the inner sleeve.

[0008] Furthermore, the outer wall of the outer edge is symmetrically fixed with a first crossbar, and a first rubber sleeve is fitted on the first crossbar.

[0009] Furthermore, the limiting support includes two suspension brackets placed vertically and in a cross shape. The corresponding ends of the two suspension brackets are fixed to the same connecting rod. The inner wall of the outer tube has a slot corresponding to the connecting rod.

[0014] (III) Beneficial Effects Compared with the prior art, the beneficial effects of this utility model are as follows: I. In this utility model, the inner sleeve of the divider is adjusted according to the required planting depth. By adjusting the inner sleeve of the divider, a distance difference is created between the bottom of the originally flush outer edge of the indicator and the inner sleeve of the divider. The side of the scale line is provided with indicator numbers, and the indicator numbers gradually increase from top to bottom along the scale line. After adjustment, the indicator number pointed to by the indicator groove is the distance difference between the bottom of the outer edge of the indicator and the bottom of the inner sleeve of the divider. The inner sleeve of the divider located at the bottom of the outer edge of the indicator is pressed into the soil. During the adjustment process, the user only needs to observe the indicator numbers on the scale line to adjust the required planting depth.

[0015] Second, in this utility model, when the bottom of the outer edge of the prompt is in contact with the ground, the inner sleeve of the separator located at the bottom of the outer edge of the prompt is pressed into the soil. The outer edge of the prompt can increase the contact area with the ground, thereby preventing the inner sleeve of the separator from shifting.

[0016] Third, in this utility model, during the process of rotating and pressing the drill rod downward, the drill rod can be limited at two points by two suspension brackets, thereby preventing the drill rod from swinging. Compared with the threaded connection, the drill rod is connected to the two suspension brackets in the form of sliding insertion. When the positioning ring contacts the positioning pull rod, the positioning pull rod will only prevent the positioning ring and the drill rod from drilling downward, but will not restrict the drill rod from driving the spiral cutter head to rotate. Thus, after reaching the predetermined drilling depth, the spiral cutter head will not go deeper, but the continued rotation of the spiral cutter head can fully drill the soil at that depth into the spiral groove on the spiral cutter head, making the inside of the excavated trench cleaner.

[0017] Fourth, in this utility model, by setting a dividing inner sleeve, the soil inside can be isolated from the soil outside, thus preventing the soil outside from collapsing inward during drilling. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1 like Figures 1-8 As shown, the breeding plot seeder includes an outer tube 1, with a partition inner sleeve 2 slidably inserted into the bottom of the outer tube 1, specifically as follows: Figure 5 and Figure 6 As shown, the top of the inner sleeve 2 is circumferentially fixed with a first insertion arc rod 22, and the side of the outer tube 1 is provided with a first arc-shaped sliding groove 101 that matches the first insertion arc rod 22. During installation, the first insertion arc rod 22 is slidably inserted into the corresponding first arc-shaped sliding groove 101. Multiple docking slots 102 are equidistantly provided on one side of the first arc-shaped slide groove 101. A docking plug 221 adapted to the docking slot 102 is fixedly connected to one side of the first insertion arc rod 22. When engaging, hold the outer tube 1 and rotate the inner sleeve 2 clockwise. At this time, the docking plug 221 will slide into one of the docking slots 102, thereby fixing the inner sleeve 2 and the outer tube 1. The docking plug 221 and the docking slot 102 are interference-fitted, thereby increasing the friction between the docking plug 221 and the docking slot 102 and preventing the docking plug 221 from easily slipping out of the docking slot 102. The operator can also increase the friction between the docking plug 221 and the docking slot 102 by nesting a rubber sleeve on the docking plug 221.

[0022] like Figure 1 As shown, the outer tube 1 has a scale line 7 on its tube wall; the scale line 7 is located on the side of one of the first arc-shaped grooves 101, and a diamond-shaped indicator groove 2201 is provided on the first insertion arc rod 22 in the first arc-shaped groove 101, with both ends of the indicator groove 2201 pointing to the scale line 7.

[0023] The bottom of the outer tube 1 is also fixedly connected to an outer edge 3, specifically: a second insertion arc rod 31 is circumferentially fixed to the top of the outer edge 3. The second insertion arc rod 31 can be made of materials with high hardness, including but not limited to stainless steel. Figure 6 As shown, the bottom of the outer tube 1 is provided with a second arc-shaped groove 103 corresponding to the second insertion arc rod 31, and the bottom of the inner sleeve 2 is provided with a relief groove. The top of the second insertion arc rod 31 passes through the relief groove and is fixedly inserted into the corresponding second arc-shaped groove 103. During installation, the top of the second insertion arc rod 31 is fixedly inserted into the corresponding second arc-shaped groove 103, and then it is fixed to the outer tube 1 with screws. At this time, the outer edge 3 is sleeved on the inner sleeve 2, and in the initial state, the outer edge 3 is flush with the bottom of the inner sleeve 2. Specifically, during adjustment, first hold the outer tube 1, then rotate the inner sleeve 2 counterclockwise to make it rotate the first insertion arc rod 22 in the same direction, thereby separating the docking plug 221 on the first insertion arc rod 22 from the corresponding docking slot 102. At this time, the operator can slide up and down along the first arc-shaped slide groove 101 to make adjustments. During the adjustment process, the position of the first insertion arc rod 22 can be adjusted according to the position of the indicator groove 2201 on the scale line 7. After the adjustment is completed, rotate the inner sleeve 2 clockwise to slide the docking plug 221 into the corresponding docking slot 102, thereby fixing the inner sleeve 2 and the outer tube 1 again. At the same time, the bottom of the originally flush outer edge 3 and the inner sleeve 2 will now have a distance difference. The scale line 7 has a prompt number on the side, and the prompt number gradually increases from top to bottom along the scale line 7. After the adjustment is completed, the prompt number indicated by the indicator groove 2201 is the distance difference between the bottom of the prompt outer edge 3 and the bottom of the inner sleeve 2.

[0024] The avoidance groove provided at the bottom of the inner sleeve 2 can prevent interference between the inner sleeve 2 and the second insertion arc rod 31 when rotating.

[0025] When digging the trench for placing the seeds, simply press the inner sleeve 2, located at the bottom of the outer edge 3, into the soil. Further, such as... Figure 2 As shown, a first crossbar 33 is symmetrically fixed to the outer wall of the outer edge 3. A first rubber sleeve 34 is fitted on the first crossbar 33 to increase the friction between the worker's hand and the first crossbar 33. The worker can press down on the first crossbar 33 to move the outer tube 1 and the inner sleeve 2 downward together, thereby pressing the inner sleeve 2 located at the bottom of the outer edge 3 into the soil. The bottom of the inner sleeve 2 is provided with a pointed tip to facilitate the pressing of the inner sleeve 2 into the soil. During the pressing process, the worker can also rotate the first crossbar 33 counterclockwise to drive the outer tube 1 and the inner sleeve 2 to rotate in the same direction, further increasing the speed of pressing the inner sleeve 2 into the soil. When the bottom of the outer edge 3 is in contact with the ground, the inner sleeve 2 located at the bottom of the outer edge 3 is already pressed into the soil. The outer edge 3 can increase the contact area with the ground, thereby preventing the inner sleeve 2 from shifting.

[0026] During the insertion process, it is necessary to avoid rotating the first crossbar 33 counterclockwise to prevent the outer tube 1 from moving in the same direction as the first crossbar 33, which would cause the docking plug 221 to separate from the docking slot 102.

[0027] like Figure 2As shown, a limiting support 4 is fixed to the inner wall of the outer cylinder 1. A drill rod 5 is slidably inserted into the limiting support 4. The bottom of the drill rod 5 extends into the inner sleeve 2. A spiral cutter head 51 is fixed to the bottom of the drill rod 5. Both the inner and outer walls of the inner sleeve 2 are provided with a nano-coating. The nano-coating can prevent stubborn soil from adhering to the wall of the inner sleeve 2. The spiral cutter head 51 is located in the inner sleeve 2. In the initial state, the outer edge 3, the inner sleeve 2, and the bottom of the spiral cutter head 51 are flush. Specifically, the limiting support 4 includes two suspension brackets 41 placed vertically and in a cross shape. The corresponding ends of the two suspension brackets 41 are fixed with the same connecting rod 42. The inner wall of the outer cylinder 1 is provided with a groove 104 corresponding to the connecting rod 42. The drill rod 5 is slidably inserted into two suspension brackets 41. A positioning ring 52 is fixedly sleeved on the drill rod 5. During assembly, the drill rod 5 with the positioning ring 52 sleeved is first slidably inserted into the two suspension brackets 41. Then, the corresponding ends of the two suspension brackets 41 are fixedly connected by the connecting rod 42. At this time, the positioning ring 52 is located between the two suspension brackets 41. Then, the two suspension brackets 41 fixedly connected by the connecting rod 42 are fixedly inserted into the slot 104 by screws. like Figure 2 and Figure 3 As shown, a positioning pull rod 21 is provided on the inner sleeve 2. One end of the positioning pull rod 21 extends into the outer tube 1 and the end is located below the positioning ring 52. Specifically, a stepped insertion port 2202 is provided on the indicator groove 2201. The positioning pull rod 21 is adapted to the insertion port 2202 and is slidably inserted into the insertion port 2202. An avoidance straight groove 105 is provided on the outer tube 1. The avoidance straight groove 105 is connected to the insertion port 2202. One end of the positioning pull rod 21 passes through the avoidance straight groove 105 and extends into the outer tube 1 and the end is located below the positioning ring 52. The other end extends into the indicator groove 2201 and the end is threadedly fixed with a widened pull head 211.

[0028] Specifically, when digging the pit for placing seeds, push the positioning rod 21 inward. At this time, one end of the positioning rod 21 extends into the outer tube 1 and the end is located below the positioning ring 52. The positioning rod 21 can limit the positioning ring 52, thereby preventing the spiral cutter head 51 from extending out of the inner sleeve 2 and causing excessive drilling. As the inner sleeve 2 at the bottom of the outer edge 3 is pressed into the soil, the soil inside the inner sleeve 2 will push the spiral cutter head 51 upward. After the inner sleeve 2 at the bottom of the outer edge 3 is pressed into the soil, the drill rod 5 will rotate and press downward. The drill rod 5 will drive the spiral cutter head 51 to rotate and move downward together, and drill a hole through the spiral cutter head 51. When the positioning ring 52 contacts the positioning pull rod 21 located below it, the bottom of the spiral cutter head 51 will be drilled to be flush with the bottom of the inner sleeve 2.

[0029] During the process of rotating and pressing the drill rod 5 downward, the drill rod 5 can be limited at two points by the two suspension brackets 41, thereby preventing the drill rod 5 from swinging. Compared with the threaded connection, the drill rod 5 is connected to the two suspension brackets 41 in the form of sliding insertion. When the positioning ring 52 contacts the positioning pull rod 21, the positioning pull rod 21 will only prevent the positioning ring 52 and the drill rod 5 from drilling downward, but will not restrict the drill rod 5 from driving the spiral cutter head 51 to rotate. Thus, after reaching the predetermined drilling depth, the spiral cutter head 51 will not go deeper, but will continue to rotate the spiral cutter head 51 to fully drill the soil at that depth into the spiral groove on the spiral cutter head 51. During the excavation process, the inner sleeve 2 can be set to isolate the soil inside from the soil outside, preventing the soil outside from collapsing inward during drilling.

[0030] After drilling is completed, the first horizontal bar 33 is pulled upward to remove the inner sleeve 2 and the spiral cutter head 51 from the drilled hole. After the seeds are placed in, the soil is covered. At this time, the positioning rod 21 is pulled outward by the widened pull head 211. The end of the positioning rod 21 located in the outer tube 1 will retract into the insertion port 2202. At this time, the positioning rod 21 stops limiting the positioning ring 52. The drill rod 5 is pushed downward to make the spiral cutter head 51 extend from the bottom of the inner sleeve 2, thereby dumping the soil on the spiral cutter head 51 and covering it with soil. After covering with soil, the drill rod 5 is pulled upward to move the spiral cutter head 51 back into the inner sleeve 2 and push the positioning rod 21 back. The positioning rod 5 is then limited by the positioning rod 21 and the positioning ring 52. Then the drilling work can be carried out directly at the next location. Among them, such as Figure 4As shown, a scraper 32 is fixed to the inner wall of the outer edge 3. The scraper 32 is slidably connected to the outer wall of the inner sleeve 2 with a nano-coating. If drilling is not required, the soil remaining on the spiral cutter head 51 and the inner sleeve 2 can be cleaned first. Then, the positioning ring 52 can be repositioned by the positioning rod 21. Then, the inner sleeve 2 can be rotated counterclockwise to make the first insertion arc rod 22 rotate in the same direction, thereby separating the docking plug 221 on the first insertion arc rod 22 from the corresponding docking slot 102. The inner sleeve 2 can be adjusted upward to zero (i.e., the indicator groove 2201 points to the top side of the scale line 7). When the inner sleeve 2 is slid upward, the soil attached to the outer wall of the inner sleeve 2 with a nano-coating can be scraped off by the scraper 32. After zeroing, the inner sleeve 2 can be rotated clockwise to fix it to the outer cylinder 1.

[0031] Example 2 like Figures 1-8 As shown, this embodiment is an improvement on embodiment one as follows: Figure 8 As shown, the seeding plot seeder also includes a seed storage tube 6. The top of the drill rod 5 has a polygonal inner insertion port 501. The bottom of the seed storage tube 6 is fixed with a plug rod 61 that matches the inner insertion port 501. The plug rod 61 is inserted into the inner insertion port 501. Seeds are placed in the seed storage tube 6, which makes it easy for staff to pick up and put in the seeds. The top of the seed storage tube 6 is fitted with a cover 62. When storing seeds, the cover 62 can prevent the seeds from spilling out. The outer wall of the seed storage tube 6 is symmetrically fixed with a second crossbar 63. The operator can rotate and press the drill rod 5 downward through the second crossbar 63. A second rubber sleeve 64 is fitted on the second crossbar 63 to increase the friction between the operator's hand and the second crossbar 63. A damping rubber ring 65 is nested on the plug rod 61. The outer wall of the damping rubber ring 65 is pressed against the inner socket 501, thereby increasing the friction between the plug rod 61 and the inner socket 501 and preventing the plug rod 61 from falling out of the inner socket 501.

[0032] In summary, the workflow of this utility model is as follows: Before starting work, make adjustments. Hold the outer tube 1 and rotate the inner sleeve 2 counterclockwise to make the first insertion arc rod 22 rotate in the same direction, thereby separating the docking plug 221 on the first insertion arc rod 22 from the corresponding docking slot 102. At this time, the first insertion arc rod 22 can slide up and down along the first arc-shaped slide groove 101. During the adjustment process, the position of the first insertion arc rod 22 can be adjusted according to the position of the indicator groove 2201 on the scale line 7. After the adjustment is completed, rotate the inner sleeve 2 clockwise to slide the docking plug 221 into the corresponding docking slot 102, thereby fixing the inner sleeve 2 and the outer tube 1 again. At the same time, the bottom of the originally flush outer edge 3 and the inner sleeve 2 will now have a distance difference, which is the drilling depth.

[0033] When digging the pit for placing seeds, the worker presses down while simultaneously rotating the first crossbar 33 counterclockwise. This causes the outer tube 1 and the inner sleeve 2 to move downwards together, thus pressing the inner sleeve 2, located at the bottom of the outer edge 3, into the soil. During the pressing process, the soil inside the inner sleeve 2 pushes the spiral cutter head 51 upwards. After the inner sleeve 2 at the bottom of the outer edge 3 is pressed into the soil, the second crossbar 63 is rotated and the drill rod 5 is pressed downwards. The drill rod 5 then drives the spiral cutter head 51 to rotate and move downwards, drilling through the spiral cutter head 51. When the positioning ring 52 contacts the positioning pull rod 21 located below it, the bottom of the spiral cutter head 51 is drilled to be flush with the bottom of the inner sleeve 2. Continuing to rotate the spiral cutter head 51 can fully drill the soil at this depth into the spiral groove on the spiral cutter head 51.

[0034] After drilling is completed, pull the first horizontal bar 33 upward to remove the inner sleeve 2 and the spiral cutter head 51 from the drilled hole. After the seeds are placed in, cover them with soil. At this time, pull the positioning rod 21 outward by widening the pull head 211. The end of the positioning rod 21 located in the outer tube 1 will retract into the insertion port 2202. At this time, the positioning rod 21 stops limiting the positioning ring 52. Push the drill rod 5 downward to make the spiral cutter head 51 extend from the bottom of the inner sleeve 2, thereby dumping the soil on the spiral cutter head 51 and covering it with soil. After covering with soil, pull the drill rod 5 upward to move the spiral cutter head 51 back into the inner sleeve 2 and push the positioning rod 21 back. Thus, the positioning rod 5 is limited by the positioning rod 21 and the positioning ring 52. Then, the drilling work can be carried out directly at the next location.

[0035] If drilling is not performed, the soil remaining on the spiral cutter head 51 and the inner sleeve 2 can be cleaned first. Then, the positioning ring 52 can be repositioned by the positioning pull rod 21. Then, the inner sleeve 2 can be rotated counterclockwise to make the first insertion arc rod 22 rotate in the same direction, thereby separating the docking plug 221 on the first insertion arc rod 22 from the corresponding docking slot 102. The inner sleeve 2 can be adjusted upward to zero (i.e., the indicator groove 2201 points to the top side of the scale line 7). When sliding the inner sleeve 2 upward, the soil attached to the outer wall of the inner sleeve 2 with the nano-coating can be scraped off by the scraper 32. After zeroing, the inner sleeve 2 can be rotated clockwise to fix it to the outer cylinder 1.

Those skilled in the art can make any selections according to their needs or convenience.
