Description

Technical Field

[0001] The invention relates to the technical field of forestry planting equipment, and specifically relates to a red pine seed spot sowing device. Background Art

[0002] Korean pine is an evergreen tree of the genus Pinus in the Pinaceae family. Its seeds are inverted ovate and triangular, and can be propagated by grafting and seed propagation. Korean pine can generally be used as a garden shade tree, a street tree, or to create a landscape forest. Korean pine is strong and rich, with a high oil content. It is an important woody oil tree species for edible and industrial use. The operator can use a sowing device to complete the sowing of Korean pine seeds. The sowing device can first make a pit on the ground and then place the Korean pine seeds in the pit. For example, the Chinese utility model patent with patent application number "CN202121991525.8" provides a seed sowing device, which includes a tube body, a seed bucket and a base. The tube body and the base are slidably plugged in. Pressing the handle on the tube body can drive the tube body and the seed bucket to move downward, so that the seed bucket creates a hole in the land. When the seed bucket reaches the expected depth in the soil, the reset spring drives the tube body and the seed bucket to move upward, and the opening piece between the base and the opening piece can drive the opening piece to rotate, so that the seeds fall into the soil through the opening on the side wall of the seed bucket.

[0003] However, the device has shortcomings. The opening piece in the device is composed of a sleeve, a sleeve rod and a spring, wherein one end of the sleeve is hinged to the inner wall of the base. When the seed bucket moves downward, the sleeve rotates around the hinge point. In addition to the pit created by the seed bucket on the ground, the sleeve and the sleeve rod will also press out an inclined groove on the ground, one end of which is connected to the pit and the other end extends to the outside of the pit. Since the sleeve, the opening piece and the opening on the seed bucket are located on the same side, and the seeds can only leave the seed bucket when the seed bucket moves upward, the seeds may fall into the groove outside the pit instead of falling into the pit of the expected depth, so that the seeds cannot grow normally.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1

[0043] See also Figure 1-20 The present invention provides a technical solution: a red pine seed spot sowing device, comprising a seed feeding tube 1, a guide tube 2, a soil-breaking head 3, a first drive assembly 4 and a second drive assembly 5. When sowing is required, the present invention is moved to a designated location, and the seed feeding channel 11 inside the seed feeding tube 1 can be placed in red pine seeds 9, and then the red pine seeds 9 in the seed feeding channel 11 will slide down into the seed feeding groove 31 inside the soil-breaking head 3. At this time, the guide tube 2 and the soil-breaking head 3 are attached together, and the retaining plate 21 at the bottom of the guide tube 2 restricts the red pine seeds 9, and the red pine seeds 9 cannot leave the soil-breaking head 3. Then the second drive assembly 5 works to drive the seed feeding tube 1, the guide tube 2 and the soil-breaking head 3 to move downward together. Since the guide tube 2 and the soil-breaking head 3 together form a conical structure, the soil on the ground can be easily broken to create a hole. Since the outer surfaces of the guide tube 2 and the soil-breaking head 3 are not connected to other objects, the edges of the holes created by the guide tube 2 and the soil-breaking head 3 are complete.

[0044] See also Figure 1 and Figure 19-20 , when the soil-breaking head 3 moves downward to the expected depth inside the soil, the second drive assembly 5 then works to drive the seed-feeding tube 1 to move upward, and at the same time the first drive assembly 4 works to drive the soil-breaking head 3 to move downward. The final effect is that the seed-feeding tube 1 drives the guide tube 2 to move upward, the soil-breaking head 3 remains in its original position, the guide tube 2 is separated from the soil-breaking head 3, and the retaining plate 21 no longer restricts the Korean pine seeds 9. At this time, the Korean pine seeds 9 in the seed-feeding groove 31 will leave the soil-breaking head 3 and enter the soil to complete the sowing. Then, the first drive assembly 4 works to drive the soil-breaking head 3 to move upward and fit with the guide tube 2 again. Finally, the second drive assembly 5 works to drive the seed-feeding tube 1, the guide tube 2 and the soil-breaking head 3 to move upward together, and the guide tube 2 and the soil-breaking head 3 move above the ground. Finally, it is only necessary to move the present invention to another location, put the Korean pine seeds 9 into the seed-feeding tube 1 again, and then the subsequent sowing operation can be carried out.

[0045] When the present invention is in use, after the seed feeding tube 1 moves downward, the guide tube 2 and the soil breaking head 3 can create a hole on the land. When the position of the soil breaking head 3 remains unchanged, the Korean pine seeds 9 can fall into the hole of the expected depth, ensuring the normal growth of the seeds.

[0046] See also Figure 1-3 , Figure 5-6 and Figure 8-9 The seeding tube 1 is provided with a seeding block 6, and each of the three side edges of the seeding block 6 is provided with a support plate 61. The seeding block 6, the three support plates 61 and the inner wall of the inner wall of the seeding tube 1 are enclosed together to form three seeding channels 11. There are also three seeding grooves 31 and three retaining plates 21. When a red pine seed 9 is placed in each of the three seeding channels 11, the three red pine seeds 9 can enter the three seeding grooves 31 respectively and be restricted by the three retaining plates 21 respectively. That is to say, when sowing, the maximum number of red pine seeds 9 sown in each hole of the present invention is three.

[0047] See also Figure 1-7 The first driving assembly 4 includes a first electric telescopic rod 41 and a driving rod 42. The first driving assembly 4 is fixedly connected to the top inner wall of the seed feeding tube 1. The output end of the first electric telescopic rod 41 is connected to the soil breaking head 3. When the first electric telescopic rod 41 is extended, the soil breaking head 3 can be driven to move downward through the driving rod 42. When the first electric telescopic rod 41 is shortened, the soil breaking head 3 can be driven to move upward through the driving rod 42. The seed separation block 6 is sleeved on the outside of the driving rod 42. When the driving rod 42 moves, the driving rod 42 can slide along the seed separation block 6.

[0048] Embodiment 2

[0049] Based on Example 1, please refer to Figure 9-10 and Figure 19-20 , a seed storage groove 32 is provided in the middle of the side wall of the seed feeding groove 31, and the bottom surface of the seed storage groove 32 is a plane. A seed pushing plate 34 is provided in the assembly port 33 on the side wall of the seed storage groove 32. Since there are three seed feeding grooves 31, there are also three seed storage grooves 32 and three seed pushing plates 34. An assembly cavity 35 is provided inside the soil-breaking head 3, and a firing assembly 7 is provided in the assembly cavity 35. When the Korean pine seeds 9 enter the seed feeding groove 31, they will fall on the plane at the bottom of the seed storage groove 32, and the seed pushing plate 34 is in a vertical state. When the guide tube 2 is separated from the soil-breaking head 3 and the retaining plate 21 no longer restricts the Korean pine seeds 9, the firing assembly 7 works and drives the three seed pushing plates 34 to rotate simultaneously. The bottom of the seed pushing plate 34 hits the Korean pine seeds 9, and pushes the Korean pine seeds 9 out of the soil-breaking head 3, and enters the soil to complete the sowing.

[0050] See also Figure 9-13, the firing assembly 7 includes a first carrier 71, a guide rod 72, a first assembly plate 73, a push rod 74, a second assembly plate 75, a spring 76 and a reset assembly 77. The top of the first carrier 71 is fixedly connected to the inner wall of the assembly cavity 35, and there are three guide rods 72, which are radially distributed. The first ends of the three guide rods 72 abut against the side walls of the three seed-pushing plates 34 respectively, and the second ends of the three guide rods 72 are fixedly connected to the bottom of the first carrier 71. The three guide rods 72 are sleeved with the first assembly plate 73, the second assembly plate 75 and the spring 76. When the guide tube 2 and the soil-breaking head 3 are attached together, the reset assembly 77 can drive the three first assembly plates 73 to move away from the seed-pushing plate 34 at the same time, and the three springs 76 are compressed to store elastic potential energy. The reset assembly 77 can also keep the three first assembly plates 73 immobile, so that the three first assembly plates 73 restrict the three springs 76, and the three springs 76 cannot release elastic potential energy to extend.

[0051] See also Fig.10 and Fig.13 When the guide tube 2 is separated from the soil-breaking head 3, the reset assembly 77 releases the three first assembly plates 73, and the three springs 76 release elastic potential energy to extend, and drive the three first assembly plates 73 to slide along the additional surfaces of the three guide rods 72. The three first assembly plates 73 are all provided with a push rod 74. When the push rod 74 hits the bottom of the seed-pushing plate 34, it can drive the seed-pushing plate 34 to rotate. Then the seed-pushing plate 34 hits the red pine seeds 9, and pushes the red pine seeds 9 out of the soil-breaking head 3 and into the soil to complete the sowing.

[0052] See also Figure 9-13 , the reset assembly 77 includes a first drive disk 771, a pull rope 772, a metal plate 773, a second drive disk 774, an electromagnet 775 and a second electric telescopic rod 776. When it is necessary to drive the first assembly plate 73 to move away from the seed pushing plate 34, the second electric telescopic rod 776 extends, driving the second drive disk 774 and the electromagnet 775 to move upward and close to the metal plate 773. Then the electromagnet 775 works to absorb the metal plate 773, and then the second electric telescopic rod 776 shortens to drive the second drive disk 774 and the electromagnet 775 to move downward, and the electromagnet 775 can drive the first drive disk 771 to move downward through the metal plate 773. Three inclined pull ropes 772 are provided on the top surface of the first drive disk 771, and the first ends of the three pull ropes 772 are fixedly connected to the first drive disk 771, and the second ends of the three pull ropes 772 are fixedly connected to the three first assembly plates 73 respectively. When the first driving disk 771 moves downward, the three first assembly plates 73 can be driven to approach the bottom center of the first carrier frame 71 through the three pull ropes 772 , and the first assembly plates 73 compress the springs 76 during the movement.

[0053] When it is necessary to drive the seed pushing plate 34 to rotate, the electromagnet 775 stops working, the metal plate 773 is released, the three pull ropes 772 no longer generate tension on the three first assembly plates 73, and the three springs 76 can release elastic potential energy to stretch and drive the three first assembly plates 73 to move, so that the push rod 74 hits the bottom of the seed pushing plate 34, and drives the three seed pushing plates 34 to rotate simultaneously.

[0054] See also Figure 1-10 and Figure 19-20 A guide block 22 is provided on the side wall of the retaining plate 21 facing the seed storage groove 32, and a concave arc-shaped guide surface 221 is provided on the top of the guide block 22, and the bottom end of the arc-shaped guide surface 221 is flush with the bottom surface of the seed storage groove 32. When the red pine seeds 9 enter the seed feeding groove 31, they will fall on the guide block 22 and slide down along the arc-shaped guide surface 221 to the plane at the bottom of the seed storage groove 32. The retaining plate 21 cooperates with the guide block 22 to prevent the red pine seeds 9 from falling into the edge gap between the seed storage groove 32 and the retaining plate 21, ensuring that the seed pushing plate 34 can collide with the red pine seeds 9 after rotating.

[0055] See also Figure 6-10 , the top surface of the soil-breaking head 3 is provided with a socket 36, and there are also three sockets 36. The three sockets 36 are respectively located on the side of the three seed-pushing plates 34 away from the assembly cavity 35. A plug plate 62 is provided in each socket 36, and the plug plate 62 is fixedly connected to the bottom surface of the seed-seeding block 6. When the soil-breaking head 3 moves downward and the guide tube 2 is separated from the soil-breaking head 3, the plug plate 62 leaves the socket 36, and the plug plate 62 no longer restricts the seed-pushing plate 34, and the seed-pushing plate 34 can rotate freely. When the soil-breaking head 3 moves upward and fits with the guide tube 2, the plug plate 62 enters the socket 36, and the bottom of the plug plate 62 drives the seed-pushing plate 34 to rotate in the opposite direction, driving the seed-pushing plate 34 to reset. The three plug plates 62 cooperate with the three guide rods 72 to jointly restrict the three seed-pushing plates 34 to remain in a vertical state.

[0056] Embodiment 3

[0057] Based on Example 2, please refer to Figure 1-2 and Figure 14-15 , a seeding assembly 8 is provided on the outer wall of the seeding tube 1, and the seeding assembly 8 includes an annular seeding box 81. The top surface of the annular seeding box 81 is provided with an annular assembly groove 811, and the bottom surface of the annular assembly groove 811 is provided with three seeding ports 812, and the interior of the annular seeding box 81 is provided with three seeding channels 813. Three Korean pine seeds 9 are respectively placed in the three seeding ports 812, and the Korean pine seeds 9 will first enter the seeding channel 813 through the seeding ports 812, and then fall into the corresponding seeding channel 11 along the inner wall of the seeding channel 813. The annular seeding box 81 is truncated cone-shaped, and the top diameter of the annular seeding box 81 is larger than the bottom diameter, so the bottom inner walls of the seeding ports 812 and the seeding channels 813 are both inclined, and the Korean pine seeds 9 can slide smoothly without getting stuck.

[0058] See also Figure 14-17 The seeding assembly 8 also includes an annular seed storage box 82, an annular cover plate 83 and a handle 84. The annular seed storage box 82 is arranged in the annular assembly groove 811, and the bottom surface of the annular seed storage box 82 is provided with three through holes 821. Open the annular cover plate 83, and then put a number of Korean pine seeds 9 into the annular seed storage box 82. At this time, only one Korean pine seed 9 can be accommodated in the through hole 821. Since the three seed discharge ports 812 and the three through holes 821 are staggered, the Korean pine seeds 9 will not fall into the seed discharge ports 812 at this time, and then cover the annular cover plate 83 to complete the preparation work of the seeding assembly 8. When sowing is required, after the present invention is moved to the designated location, the operator holds and rotates the handle 84, and the handle 84 can drive the annular seed storage box 82 to rotate together through the annular cover plate 83. During the rotation of the annular seed storage box 82, the three through holes 821 will overlap with the three seeding ports 812 at the same time, and the three Korean pine seeds 9 will fall into the three seeding ports 812 at the same time and slide into the three seed feeding channels 11. Since the annular seed storage box 82 will continue to rotate, when other Korean pine seeds 9 enter the through holes 821, the through holes 821 have been staggered with the seeding ports 812, so there will be no situation where two Korean pine seeds 9 enter the same seeding port 812 in succession. After the operator drives the handle 84 to rotate 120°, the handle 84 is released, and then the second drive assembly 5 works, and then the subsequent pit making and sowing operations are performed.

[0059] See also Fig.16 When the number of seeds sown in each hole is desired to be changed, a partition (not shown in the partition diagram) can be placed in the annular seed storage box 82 to divide the annular seed storage box 82 into one to three areas, each of which contains only one through hole 821. When a number of Korean pine seeds 9 are placed in the annular seed storage box 82, the number of seeds sown in each hole can be reduced by not placing Korean pine seeds 9 in one or two areas.

[0060] See also Figure 1 and Fig.18 The second driving assembly 5 includes a second bearing frame 51 and a third electric telescopic rod 52. The seeding tube 1 is arranged on the inner side of the second bearing frame 51. The third electric telescopic rod 52 is fixedly arranged on the top of the second bearing frame 51. The output end of the third electric telescopic rod 52 faces downward and is fixedly connected to the top of the seeding tube 1. When the third electric telescopic rod 52 is extended, the seeding tube 1 can be driven to move downward. When the third electric telescopic rod 52 is extended and shortened, the seeding tube 1 can be driven to move upward. The bottom of the second driving assembly 5 is in a circular shape, which can have a large contact area with the ground, so the present invention will not sink when placed on the ground.

[0061] See also Figure 1 and Figure 17-19, there are two handles 84, and the second drive assembly 5 also includes two stoppers 53. The operator can drive the annular seed storage box 82 to rotate by holding any one of the handles 84. After the handle 84 rotates 120°, it will be restricted by the stopper 53, and the handle 84 and the annular seed storage box 82 cannot continue to rotate, thereby preventing the situation where two Korean pine seeds 9 enter the same seed discharge port 812 due to misoperation. When sowing is completed at one location and the present invention is moved to another location, it is only necessary to rotate the handle 84 in the opposite direction by 120°, and the Korean pine seeds 9 in the annular seed storage box 82 can still fall into the seed entry channel 11 for subsequent sowing operations.
