Description

Technical Field

[0001] The present invention relates to the technical field of sowing equipment, and in particular to an intelligent seeder with adjustable sowing depth. Background Art

[0002] As a vital agricultural machinery equipment, the seeder plays a vital role in agricultural production. Its core function is to sow crop seeds into the soil of farmland in a precise and uniform manner. This process is achieved through highly mechanized operations, which significantly improves the efficiency and accuracy of sowing. At the same time, the use of the seeder also greatly reduces the labor intensity of farmers, making the agricultural production process more efficient and humane.

[0003] At present, seeders have been widely used in the planting of various crops, including but not limited to wheat, corn, soybeans and rice. However, although the existing seeder technology performs well in yield-based sowing, for some small experimental lands, the use of large seeders for sowing often seems too luxurious and wasteful. This is because the area of ​​small experimental lands is limited and often requires more sophisticated and personalized sowing operations. In this case, the use of large seeders will not only cause a waste of resources, but may also fail to meet the special requirements of the experimental land for sowing accuracy.

[0004] In addition, the seed drills in the prior art also have certain inconveniences when dealing with sowing in soils of different depths. Since the depth and texture of the soil have an important influence on the growth and development of seeds, in the actual sowing process, it is often necessary to adjust the sowing depth according to the specific conditions of the soil. However, the existing seed drills often have certain limitations and inconveniences in adjusting the sowing depth, which to a certain extent limits the scope of application and effect of the seed drill. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the prior art seeders also have certain inconveniences when sowing in soils of different depths. Since the depth and texture of the soil have an important influence on the growth and development of seeds, in the actual sowing process, it is often necessary to adjust the sowing depth according to the specific conditions of the soil.

[0012] As a further description of the above technical solution:

[0013] The telescopic member includes a welding plate connected to the bottom of the connecting frame, and a lifting groove is opened inside the welding plate, a mounting rod is connected between the inner walls of the lifting groove, and a lifting block is slidably connected to the outer periphery of the mounting rod, a telescopic spring is sleeved on the outer periphery of the mounting rod, one side of the lifting block extends out of the lifting groove and is connected to an extension plate, and one end of the extension plate is connected to a contact block that contacts the moving rod.

[0014] As a further description of the above technical solution:

[0015] The outer periphery of the contact block is provided with an arc chamfer that contacts the abutting rod.

[0016] As a further description of the above technical solution:

[0017] The sowing piece includes an L-shaped connecting plate connected to one side of the lifting block, the two L-shaped connecting plates are connected by a connecting rod, the outer periphery of the connecting rod is rotatably connected to a plurality of rotating sleeve blocks, and the bottoms of the plurality of rotating sleeve blocks are fixedly connected to two symmetrical conical barrels, and the conical barrels are connected to a deflection piece through an outer peripheral extension rod.

[0022] As a further description of the above technical solution:

[0023] The unloading assembly includes a placing plate connected to the top of the connecting frame, and a unloading barrel is installed on the top of the placing plate, the bottom of the unloading barrel is fixedly connected to an annular box through the unloading plate, and the inside of the annular box is rotatably connected to a rotating block, a placing port is opened inside the rotating block, and a discharge port is opened on the outer periphery of the annular box.

[0024] As a further description of the above technical solution:

[0025] The rotating block is installed on the outer circumference of the rotating rod.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] In the seeding operation, the seeder is first moved to the designated land, and the operator drives the connecting frame and the forward wheel to rotate by moving the push handle, which in turn drives the rotating rod to rotate. While moving forward, the soil is effectively turned over by the turning block to prepare for seeding;

[0028] Before sowing, the seeds are placed in the discharge barrel and flow into the placement port on the rotating block along the discharge plate. As the rotating rod rotates, the fixed plate rotates synchronously, and through the linkage mechanism of the sliding rod and the connecting rod, the rotation force is effectively transmitted to the mounting plate and the rotating rod, thereby driving the rotating block to rotate. During this process, the seeds in the placement port gradually move to the discharge port and finally fall into the closed conical barrel.

[0029] As the mounting plate continues to rotate, the abutting rod rotates synchronously and gradually contacts the contact block, pushing it down. The lifting block slides along the mounting rod during the descent process and stretches the telescopic spring. At the same time, the L-shaped connecting plate drives the connecting rod and the conical barrel down, so that the conical barrel is gradually inserted into the turned soil. As the connecting rod continues to descend, the extension rod is restricted in the avoidance groove and deflects, driving the conical barrel to open in the soil, and the seeds fall into the soil.

[0030] When the abutting rod is separated from the contact block, the telescopic spring rebounds, pulling the lifting block and the contact block to reset, and the conical barrel is also closed at the same time. The descending depth and opening range of the conical barrel can be adjusted by the synchronous extension of the first electric push rod and the second electric push rod to meet the planting requirements of different depths. The extension of the second electric push rod also extends the distance between the vertical groove and the avoidance groove, further facilitating the opening of the conical barrel.

[0031] In addition, as the sliding distance of the sliding rod in the slot increases, its rotation speed slows down, resulting in a lower frequency of opening of the conical barrel. This design makes the spacing between seeds larger the deeper the conical barrel descends. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] 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.

[0048] like Figure 1-Figure 10 As shown, the present invention provides an intelligent seed drill with adjustable sowing depth: comprising a frame 10, the frame 10 comprising a connecting frame 11, the interior of the connecting frame 11 is rotatably connected to a rotating rod 12, the outer periphery of the rotating rod 12 is fixedly connected to a forward wheel 13, the inner wall of the connecting frame 11 is rotatably connected to a rolling wheel 14, a baffle 15 is installed at the bottom of the connecting frame 11, the baffle 15 is arranged to prevent soil blocks from obstructing the sowing assembly 40, and the top of the connecting frame 11 is connected to a push handle 16 through a fixing screw;

[0049] When sowing is needed, the seeder must first be moved to the land to be sown. Then, the operator moves and pushes the handle 16 so that the handle 16 can drive the connecting frame 11 connected thereto to move together. Since the forward wheel 13 keeps in contact with the ground, as the forward wheel 13 continues to rotate, it will further drive the rotating rod 12 connected thereto to rotate together.

[0050] like Figure 1 , Figure 2As shown, it also includes: a soil turning assembly 20 and a material feeding assembly 30 assembled on one side of the connecting frame 11, the soil turning assembly 20 includes a mounting frame 21 connected to one side of the connecting frame 11, and a soil turning block 23 is installed on one side of the mounting frame 21 through a mounting screw 22, and the soil turning block 23 is set to be triangular, which is convenient for turning the soil;

[0051] As the forward wheel 13 moves forward, the turning block 23 firmly fixed by the mounting screws 22 moves together, so that the turning block 23 can effectively turn the ground, causing the soil to roll to both sides, thereby achieving the purpose of loosening the soil, and as the forward wheel 13 continues to move, the rolling wheel 14 at the rear will compact the land where the seeds are planted.

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the material discharge assembly 30 includes a placement plate 31 connected to the top of the connecting frame 11, and a material discharge barrel 32 is installed on the top of the placement plate 31, and the bottom of the material discharge barrel 32 is fixedly connected to an annular box 34 through a material discharge plate 33, and a rotating block 35 is rotatably connected inside the annular box 34, a placement port 351 is opened inside the rotating block 35, and a discharge port 352 is opened on the outer periphery of the annular box 34, and the rotating block 35 is fixedly installed on the outer periphery of the rotating rod 41;

[0053] Before preparing to sow the land, the seeds to be sown need to be placed in the discharge barrel 32. These seeds will then flow smoothly into the placement port 351 on the rotating block 35 along the discharge plate 33. At the same time, when the rotating rod 41 starts to rotate, it will drive the rotating block 35 to rotate synchronously. This rotation action causes the seeds in the placement port 351 to gradually move toward the discharge port 352. As the rotating rod 41 continues to rotate, the seeds will eventually smoothly fall from the discharge port 352 into the conical barrel 452 which is in a closed state at this time.

[0054] It is worth noting that the state of the conical barrel 452 has an important influence on the flow path of the seeds. When the conical barrel 452 is in an open state, the position of the placement port 351 corresponds to the discharge plate 33, so that the seeds can flow smoothly from the discharge plate 33 into the placement port 351. When the conical barrel 452 is in a closed state, the position of the placement port 351 corresponds to the discharge port 352. In addition, there is another key point. When the position of the placement port 351 is not connected with the discharge plate 33, the seeds on the discharge plate 33 will not continue to fall, but will stay on the outer wall of the rotating block 35. Only when the placement port 351 is connected with the discharge plate 33 again, the seeds will continue to flow from the discharge plate 33 into the placement port 351. The whole design ensures that the seeds can flow and be distributed according to the predetermined path and rhythm.

[0055] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, symmetrical sowing assemblies 40 are installed on both sides of the connecting frame 11, and the sowing assembly 40 includes a rotating rod 41 rotatably connected to the inside of the connecting frame 11, and the outer periphery of the rotating rod 12 is fixedly connected to a fixing plate 411, and the outer periphery of the rotating rod 41 is fixedly connected to a mounting plate 412, and the fixing plate 411 and the mounting plate 412 are connected by an adjusting member, and the adjusting member includes a slot 413 opened in the fixing plate 411 and the mounting plate 412, and the inner walls of the two slots 413 are slidably connected to sliding rods 414, and the two sliding rods 414 are connected to each other. The two sliding rods 414 are connected by a connecting rod 416, and the connecting rod 416 is rotatably sleeved on the outer periphery of the two sliding rods 414. One end of the two sliding rods 414 passes through the connecting rod 416 and is connected to the limiting plate 415. A first electric push rod 42 is installed on one side of the mounting plate 412, and a sleeve block 421 sleeved on the outer periphery of the sliding rod 414 is fixedly connected to the bottom of the first electric push rod 42, and the sleeve block 421 is rotatably connected to the sliding rod 414. The outer periphery of the sleeve block 421 is fixedly connected to the abutting rod 43, and the bottom of the connecting frame 11 is connected to a telescopic member in contact with the abutting rod 43;

[0056] When the rotating rod 12 rotates, it will drive the fixed plate 411 to rotate at the same time. As the fixed plate 411 rotates, the rotational force is effectively transmitted to the sliding rod 414 inside the mounting plate 412 through the linkage transmission mechanism of the sliding rod 414 and the connecting rod 416, which makes the sliding rod 414 rotate accordingly, and further drives the mounting plate 412 and the rotating rod 41 connected thereto to rotate together. As the mounting plate 412 continues to rotate, the mounting plate 412 drives the sliding rod 414 to move together, and makes the sleeve block 421 sleeved on the outer periphery of the sliding rod 414 drive the abutting rod 43 to move together, and abut the telescopic part during the rotation.

[0057] The telescopic member includes a welding plate 44 connected to the bottom of the connecting frame 11, and a lifting groove 441 is opened inside the welding plate 44, a mounting rod 442 is connected between the inner walls of the lifting groove 441, and a lifting block 443 is slidably connected to the outer periphery of the mounting rod 442, a telescopic spring 447 is sleeved on the outer periphery of the mounting rod 442, and the two ends of the telescopic spring 447 are respectively connected to the inner wall of the lifting groove 441 and one side of the lifting block 443, one side of the lifting block 443 extends out of the lifting groove 441 and is fixedly connected to an extension plate 444, and one end of the extension plate 444 is fixedly connected to a contact block 445 in contact with the abutting rod 43, and the outer periphery of the contact block 445 is provided with an arc chamfer 446 in contact with the abutting rod 43, and a sowing member is connected between the two telescopic members;

[0058] As the push rod 43 rotates, it will gradually come into contact with the arc chamfer 446 on the outer periphery of the contact block 445. During the contact process, the push rod 43 will push the contact block 445, especially the lifting block 443 connected to one side of the contact block 445 through the extension plate 444, so that it begins to descend. During the descent, the lifting block 443 will slide smoothly along the outer periphery of the mounting rod 442. At the same time, as the lifting block 443 continues to descend, it will simultaneously stretch the telescopic spring 447 connected to it.

[0059] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, the sowing member includes an L-shaped connecting plate 45 fixedly connected to one side of the lifting block 443, and the two L-shaped connecting plates 45 are connected by a connecting rod 454. The outer periphery of the connecting rod 454 is rotatably connected to a plurality of rotating sleeves 451, and the bottom of the plurality of rotating sleeves 451 is fixedly connected to two symmetrical conical barrels 452. The conical barrel 452 is connected to a deflection member through an extension rod 453 fixedly connected to the outer periphery. The deflection member includes a connecting plate 46 fixedly connected to one side of the welding plate 44, and The bottom of the connecting plate 46 is connected to a moving plate 462 through a second electric push rod 461, and sleeve plates 463 are fixedly connected to both sides of the moving plate 462. Two positioning blocks 464 are installed on one side of the welding plate 44. The sleeve plate 463 is slidably connected to the outer periphery of the positioning block 464, and a vertical groove 465 is provided inside the positioning block 464. An avoidance groove 466 connected to the vertical groove 465 is provided inside the sleeve plate 463, and the inner walls of the vertical groove 465 and the avoidance groove 466 are in contact with the extension rod 453.

[0060] As the lifting block 443 descends, it drives the L-shaped connecting plate 45 to move at the same time. The descending of the L-shaped connecting plate 45 causes the connecting rod 454 to move accordingly, and the connecting rod 454 further drives the peripheral rotating sleeve block 451 and the conical barrel 452 connected thereto to descend together. As the extension rod 453 on the periphery of the conical barrel 452 descends, it moves along the vertical groove 465 of the positioning block 464. In this process, the conical barrel 452 is gradually inserted into the soil turned over by the turning block 23.

[0061] As the extension rod 453 continues to move, it gradually enters the avoidance groove 466 provided in the sleeve plate 463. As the connection rod 454 continues to descend, the extension rod 453 is restricted in the avoidance groove 466 and deflects. This deflection drives the rotating sleeve block 451 connected to the conical barrel 452 to deflect to a certain extent with the connection rod 454 as the center, so that the two conical barrels 452 are opened in the soil. After opening, the seeds inside the two conical barrels 452 fall into the soil along the gap.

[0062] When the abutment rod 43 is separated from the abutment with the contact block 445, the telescopic spring 447 in the stretched state begins to rebound and pulls the lifting block 443 to rise. As the lifting block 443 rises, it drives the contact block 445 to reset through the extension plate 444. At the same time, the L-shaped connecting plate 45 also drives the connecting rod 454 to rise. The rise of the connecting rod 454 makes the deflected extension rod 453 gradually return to the center line of the vertical groove 465. At this time, the two conical barrels 452 are also closed. As the connecting rod 454 continues to rise, the extension rod 453 that has returned to its original position returns to its original position along the avoidance groove 466 and the vertical groove 465.

[0063] When planting at different depths is required, the first electric push rod 42 and the second electric push rod 461 can be started at the same time to extend, and the extension lengths are the same. The first electric push rod 42 pushes the sliding rod 414 connected to the sleeve block 421 to slide along the slot 413. Since the position of the sliding rod 414 inside the mounting plate 412 changes and its position is fixed by the sleeve block 421, the sliding rod 414 will pull the sliding rod 414 inside the fixed plate 411 to move synchronously through the connecting rod 416. When the first electric push rod 42 drives the sleeve block 421 to extend, the abutting rod 43 will also extend synchronously, thereby changing the abutting descending position of the abutting rod 43 against the contact block 445. This change is transmitted through the lifting block 443 and the L-shaped connecting plate 45, so that the connecting rod 454 drives the conical barrel 452 to descend to different depths.

[0064] At the same time, since the extension length of the second electric push rod 461 is the same as that of the first electric push rod 42, it pushes the moving plate 462 to move, so that the moving plate 462 drives the sleeve plate 463 to slide along the outer periphery of the positioning block 464, so that the distance between the vertical groove 465 and the avoidance groove 466 is also relatively extended, which facilitates the opening of the conical barrel 452;

[0065] In addition, as the sliding distance of the sliding rod 414 in the groove 413 increases, the speed at which the sliding rod 414 rotates one circle relative to the mounting plate 412 will slow down, which means that the abutment frequency of the abutment rod 43 will decrease, thereby causing the frequency of the opening of the conical barrel 452 to slow down. As the conical barrel 452 descends deeper, the spacing between the seeds will become larger.

[0066] Working principle: During the sowing process, the seeder must first be moved to the land to be sown. The operator moves the push handle 16 to drive the connecting frame 11 and the forward wheel 13 to move. The rotation of the forward wheel 13 drives the rotating rod 12 to rotate, and the turning block 23 turns the soil as it moves. Before sowing, the seeds are placed in the discharge barrel 32, and the seeds flow along the discharge plate 33 into the placement port 351 of the rotating block 35;

[0067] The rotation of the rotating rod 12 is transmitted to the rotating rod 41 through the linkage of the fixed plate 411, the sliding rod 414 and the connecting rod 416, driving the rotating block 35 to rotate, so that the seeds move toward the discharge port 352 and finally fall into the conical barrel 452. As the mounting plate 412 rotates, the abutting rod 43 contacts the arc chamfer 446 of the contact block 445, pushing the contact block 445 and the lifting block 443 down, and stretching the telescopic spring 447. The descent of the lifting block 443 drives the L-shaped connecting plate 45 and the connecting rod 454 to move, thereby causing the conical barrel 452 to descend and insert into the turned soil.

[0068] As the connecting rod 454 descends, the extension rod 453 is limitedly deflected in the avoidance groove 466, driving the conical barrel 452 to open, and the seeds fall into the soil. After the abutting rod 43 is separated from the contact block 445, the telescopic spring 447 rebounds, pulling the lifting block 443 and the contact block 445 to reset, and the conical barrel 452 is closed at the same time;

[0069] If the planting depth needs to be adjusted, the first electric push rod 42 and the second electric push rod 461 can be started simultaneously to extend, changing the positions of the sliding rod 414 and the abutting rod 43, as well as the distance between the vertical groove 465 and the avoidance groove 466, so as to adjust the descending depth and opening frequency of the conical barrel 452. As the sliding distance of the sliding rod 414 in the slot 413 increases, the speed at which the sliding rod 414 rotates one circle relative to the mounting plate 412 will slow down, which means that the abutting frequency of the abutting rod 43 will decrease, thereby causing the frequency of the opening of the conical barrel 452 to slow down. As the conical barrel 452 descends deeper, the spacing between seeds will become larger.
