Abstract
Description
Technical Field
[0001] The invention relates to the technical field of sowing devices, in particular to a sowing tray used for planting bean crops. Background Art
[0002] At present, most seeding discs are mainly used in large agricultural machinery. They are characterized by large size and complex structure, and are mostly used for seeding operations in plain areas. The core function of these seeding devices is realized by seeding devices, which are mainly divided into two categories: air suction type and mechanical type.
[0003] The working principle of the air-suction seed meter is to use negative pressure to absorb the seeds, and when the seeds are rotated to the seed drop port, they are dropped into the soil. However, this seeding method requires an additional fan on the equipment, which not only increases the size of the device, but also increases energy consumption; more importantly, the air-suction seed meter is mainly suitable for single-seed sowing of regular-shaped seeds, and is difficult to apply to other types or irregular-shaped seeds, which limits its application range to a certain extent; at the same time, due to the complexity of its working principle, the sowing efficiency of the air-suction seed meter is relatively low.
[0004] In contrast, mechanical seeders achieve quantitative sowing through the rotation of groove wheels or scoop wheels; although this method improves sowing efficiency to a certain extent, it is difficult to control the amount of seeds released; mechanical seeders often cannot ensure that every seed can fall completely into the seed furrow, thus affecting the sowing effect. Although mechanical seeders may be better than air suction types in sowing speed, the stability of their sowing quality needs to be improved.

[0022] 3. This scheme sets up a seed pressing mechanism which can drive the push rod to push the sieve holes of the powder screen through the rotation of the roller, thereby preventing the seeds from being blocked in the sieve holes, thereby reducing the phenomenon of seed leakage and under-sowing.

[0037] 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.
[0038] The present invention is further described in detail below based on the accompanying drawings and embodiments.
[0039] For example, please refer to Figures 1 to 8 As shown:
[0040] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a seeding tray for bean crop planting, including a bracket 1, a tray 11 is installed on the bracket 1, a drain tube 12 is installed below the tray 11, a powder sieve plate 13 is arranged above the tray 11, a temporary storage bin 14 is rotatably connected to the upper surface of the powder sieve plate 13, and a curved guide plate 15 is fixedly connected to the middle of the temporary storage bin 14. A seeding tray for bean crop planting also includes a depth adjustment mechanism 2, a quick locking mechanism 3 and a seed pressing mechanism 4;
[0041] The depth adjustment mechanism 2 is arranged on the lower surface of the powder sieve plate 13, and the depth adjustment mechanism 2 is used to adjust the amount of beans fed;
[0042] The quick-engaging mechanism 3 is arranged on the delivery support plate 17, and the quick-engaging mechanism 3 is used for the quick disassembly of the seed pressing mechanism 4;
[0043] The seed pressing mechanism 4 is arranged on the upper surface of the powder sieve plate 13, and the seed pressing mechanism 4 is used for auxiliary feeding of beans;
[0044] The inner wall of the temporary storage bin 14 is fixedly connected with a seed sweeping plate 16 and a placing support plate 17, and a screw 18 is installed around the outer circumference of the temporary storage bin 14 and the tray 11, and a buffer spring 19 is sleeved on the outer surface of the bottom of the screw 18;
[0045] Among them, one end of the seed sweeping plate 16 is fixed to the inner wall of the temporary storage bin 14 by bolts, and the bottom of the other end of the seed sweeping plate 16 slides on the sieve hole surface of the powder sieve plate 13. The seed sweeping plate 16 is used to block the seeds outside the sieve holes of the powder sieve plate 13 so that the seeds can fall into the sieve holes evenly; the delivery support plate 17 is used to support the adjustment of the quick locking mechanism 3 and the seed pressing mechanism 4. After the filter cylinder 12 and the tray 11 are connected in the center, the tray 11 and the filter cylinder 12 are fixed by welding.
[0046] Specifically, Figure 4 and Figure 5 As shown, the driving tooth 21 is rotatably connected to the lower surface of the powder sieve plate 13, the tooth surface of the driving tooth 21 is meshed with a threaded driving plate 22, the threaded driving plate 22 is rotatably connected to the bottom of the powder sieve plate 13, the outer surface of the threaded driving plate 22 is threadedly connected to an adjustment plate 23, the outer surface of the adjustment plate 23 is slidably connected to a limit plate 24, the limit plate 24 is fixedly connected to the bottom of the powder sieve plate 13, and the limit plate 24 is sleeved on the outer side of the threaded driving plate 22;
[0047] A micro servo motor is installed at the bottom of the powder sieve plate 13 , and a driving shaft of the servo motor is fixedly connected to the middle of the driving tooth 21 .
[0048] In the present scheme, the rotation of the micro servo motor can drive the driving teeth 21 to drive the threaded driving plate 22 to rotate in the same direction. Through the threaded connection between the outer surface of the threaded driving plate 22 and the adjusting plate 23 and the limiting action of the limit plate 24 and the outer surface of the adjusting plate 23, the rotation of the threaded driving plate 22 can drive the adjusting plate 23 to slide up and down in the limiting plate 24. The up and down sliding adjustment of the adjusting plate 23 can drive the mutual extension between the first material guide barrel 25 and the second material guide barrel 26, so that the depth adjustment between the second material guide barrel 26 and the first material guide barrel 25 can be controlled; when the seeds fall into the second material guide barrel 26 through the plugging hole of the powder screen plate 13, the storage amount of the seeds in the second material guide barrel 26 can be controlled by adjusting the second material guide barrel 26 and the first material guide barrel 25. Therefore, the falling amount of the seeds can be controlled and adjusted by the rotation of the driving teeth 21.
[0049] Further, if Figure 4 As shown, the upper surface of the tray 11 is fixedly connected to a limit baffle 29, the inner wall of the limit baffle 29 is slidably connected to a pressure plate 27, the circumference of the lower surface of the pressure plate 27 is fixedly connected to a return spring 28, one end of the return spring 28 away from the pressure plate 27 is fixedly connected to the limit baffle 29, the adjustment plate 23 slides on the upper surface of the pressure plate 27, the middle circumference of the adjustment plate 23 is fixedly connected to a first material guide cylinder 25, the inner wall of the first material guide cylinder 25 is slidably connected to a second material guide cylinder 26, and one end of the second material guide cylinder 26 away from the first material guide cylinder 25 is fixedly connected to the outer periphery of the sieve hole of the powder sieve plate 13;
[0050] Among them, the pressure plate 27 adopts a double-layer slide plate setting, and the slide plates are slidably connected to each other. A driving motor is installed in the middle of the tray 11, and the driving shaft of the driving motor is slidably connected to the middle of the powder sieve plate 13. The powder sieve plate 13 can be quickly disassembled through the limit block set on the driving shaft.
[0051] This solution adopts an elastic setting of the return spring 28. When the depth of the second material guide cylinder 26 and the first material guide cylinder 25 is adjusted, the elastic extension of the return spring 28 can synchronously control the pressure plate 27 and the bottom of the adjustment plate 23 to always remain in contact, thereby preventing the seeds from falling and allowing the seeds to fall evenly along the leakage holes.
[0052] Specifically, Figure 6 As shown, the T-shaped plug plate 31 is slidably connected to the middle part of the delivery support plate 17, a slot 32 is linearly opened on the T-shaped plug plate 31, an L-shaped card plate 33 is clamped in the slot 32, the bottom of the L-shaped card plate 33 is slidably connected to the upper surface of the delivery support plate 17, and a compression spring 34 is fixedly connected to the end of the L-shaped card plate 33 away from the T-shaped plug plate 31, and the end of the compression spring 34 away from the L-shaped card plate 33 is fixedly connected to the delivery support plate 17;
[0053] Among them, a guide groove is opened at the bottom of the end of the delivery support plate 17 away from the temporary storage bin 14, and one side of the roller 41 slides in the guide groove, and the contact height of the roller 41 and the plugging hole of the powder sieve plate 13 can be controlled by adjusting and pulling the T-shaped plug plate 31, so that the contact height of the roller 41 and the plugging hole of the powder sieve plate 13 can be accurately adjusted, which can prevent the roller 41 from being too high and unable to squeeze the sieve hole to feed the material, and can also prevent the roller 41 from rotating and engaging due to the large contact distance between the roller 41 and the plugging hole of the powder sieve plate 13.
[0054] At the same time, when sowing seeds of different sizes, such as mung beans and soybeans, it is only necessary to replace a powder sieve plate 13 and a roller 41 with a suitable aperture size to sow with the same equipment.
[0055] Specifically, Figure 7 As shown, the middle part of one side of the roller 41 is movably connected to the delivery support plate 17, and a fixed support plate 44 is arranged in the middle part of the roller 41, one end of the fixed support plate 44 is rotatably connected to the inner wall of the roller 41, and the other end of the fixed support plate 44 is fixedly connected to the bottom end of the T-shaped plug plate 31; roller pressing blocks 42 are evenly arranged on the circumference of the outer surface of the roller 41, and a push rod 48 is slidably connected in the roller pressing block 42, and a conical spring 49 is sleeved on the outer surface of the push rod 48, one end of the conical spring 49 is fixedly connected to the push rod 48, and the other end of the conical spring 49 is fixedly connected to the inner wall of the roller 41;
[0056] The contact distance between the roller 41 and the sieve holes of the powder sieve plate 13 is adjusted by the quick engagement mechanism 3 , and the roller 41 can start to rotate due to the mutual squeezing of the sieve holes of the powder sieve plate 13 and the roller pressing block 42 under the rotation of the powder sieve plate 13 .
[0057] Furthermore, an extrusion protrusion 43 is fixedly connected to the circumference of the middle part of the inner wall of the roller 41, an extrusion slide shaft 46 is symmetrically slidably connected in the fixed support plate 44, an extrusion block 45 is fixedly connected to the upper end of the extrusion slide shaft 46, and the end of the extrusion block 45 away from the extrusion slide shaft 46 is set to a rounded corner; a tension spring 47 is sleeved on the outer surface of the extrusion slide shaft 46, one end of the tension spring 47 is fixedly connected to the bottom of the fixed support plate 44, and the other end of the tension spring 47 is fixedly connected to the extrusion slide shaft 46, and the end of the extrusion slide shaft 46 away from the fixed support plate 44 is set to a rounded corner;
[0058] In this solution, when the roller 41 rotates, the convex corner of the extrusion block 43 is used to squeeze the upper end of the extrusion block 45, driving the extrusion slide shaft 46 to squeeze the push rod 48, so that the roller block 42 and the sieve holes of the powder sieve plate 13 can be squeezed and rotated against each other. At the same time, the seeds in the sieve holes of the powder sieve plate 13 can be pushed to the discharge port below by the push rod 48, so that the seeds can be automatically discharged. At the same time, the seed sowing amount can be controlled by the depth adjustment mechanism 2 to achieve precise control of the seed discharge. By adjusting the roller 41 and the T-shaped plug plate 31 rolling height, this solution can ensure that the sowing wheel and the plug hole are more closely matched, thereby reducing the phenomenon of seed leakage or over-sowing, and improving the accuracy and consistency of sowing. In addition, since the sizes of different types of bean seeds may be different, by adjusting the roller 41 rolling height, it can adapt to seeds of different sizes, ensuring that each seed can be properly processed, and improving the versatility of sowing.
[0059] Everything in the above example works like this:
[0060] Initial state: the motor is not started
[0061] The following is the working process of the quick engagement mechanism 3 to adjust the height of the roller 41 and the powder sieve plate 13:
[0062] First, before starting the device, Figure 5 As shown, first select the powder sieve plate 13 with the same aperture as the type of sowing to install and replace. At this time, the operator first synchronously disassembles the screw 18, selects the powder sieve plate 13 with the appropriate aperture, and then synchronously installs the powder sieve plate 13 again;
[0063] When the powder sieve plate 13 is replaced, Figure 6 As shown, the height of the roller 41 and the powder sieve plate 13 are adjusted to adapt to each other, and the operator further manually pulls the L-shaped clamping plate 33 to the right. After the compression spring 34 begins to be compressed, the L-shaped clamping plate 33 and the clamping slot 32 are released from the clamping state. At this time, the operator pulls the T-shaped plug plate 31 to adjust the roller 41 and the T-shaped plug plate 31 to a suitable height. At this time, the operator can release the pulling of the L-shaped clamping plate 33. At this time, the elastic extension of the compression spring 34 can drive the L-shaped clamping plate 33 to engage with the clamping slot 32 again, so that the T-shaped plug plate 31 is locked in the delivery support plate 17 again. This solution can ensure a tighter fit between the sowing wheel and the plug hole by adjusting the rolling height of the roller 41 and the T-shaped plug plate 31, thereby reducing the phenomenon of missed or over-sowing of seeds and improving the accuracy and consistency of sowing. In addition, since the sizes of different types of bean seeds may vary, by adjusting the rolling height of the roller 41, it can adapt to seeds of different sizes, ensuring that each seed can be properly processed, thereby improving the versatility of sowing.
[0064] The following is the working process of the depth adjustment mechanism 2 for adjusting the height of the first material guide cylinder 25 and the second material guide cylinder 26:
[0065] First, Figure 5 As shown, since a micro servo motor is installed at the bottom of the powder sieve plate 13, and the servo motor drive shaft is fixedly connected to the middle of the driving tooth 21, the rotation of the micro servo motor in this scheme can drive the driving tooth 21 to drive the threaded driving plate 22 to rotate in the same direction. Through the threaded connection between the outer surface of the threaded driving plate 22 and the adjusting plate 23 and the limiting action of the limiting plate 24 and the outer surface of the adjusting plate 23, the rotation of the threaded driving plate 22 can drive the adjusting plate 23 to slide up and down in the limiting plate 24, and the up and down sliding adjustment of the adjusting plate 23 can drive the mutual extension between the first material guide barrel 25 and the second material guide barrel 26, so that the depth adjustment between the second material guide barrel 26 and the first material guide barrel 25 can be controlled; when the seeds fall into the second material guide barrel 26 through the plugging hole of the powder sieve plate 13, the storage amount of the seeds in the second material guide barrel 26 can be controlled by adjusting the second material guide barrel 26 and the first material guide barrel 25, so the falling amount of the seeds can be controlled and adjusted by the rotation of the driving tooth 21.
[0066] The following is the process of the seed pressing mechanism 4 assisting the seeds to fall in the sieve holes of the powder sieve plate 13:
[0067] like Figure 7 As shown, when the roller 41 starts to rotate on the delivery support plate 17 under the mutual squeezing action of the sieve holes of the powder sieve plate 13, since the fixed support plate 44 is fixedly connected to the T-shaped plug plate 31, the rotation of the roller 41 drives the squeezing protrusion 43 to rotate synchronously. At the same time, after the convex surface of the squeezing protrusion 43 squeezes the upper end of the squeezing block 45, the squeezing block 45 starts to drive the squeezing slide shaft 46 to slide downward, and the tension spring 47 is stretched. When the squeezing slide shaft 46 slides downward, it squeezes the push rod 48. At this time, the push rod 48 starts to slide along the roller pressure block 42 toward the sieve holes of the powder sieve plate 13, and the conical spring 49 is compressed. The pushing of the seeds in the sieve holes of the powder sieve plate 13 by the push rod 48 can prevent the phenomenon of seed leakage or under-sowing caused by seeds being blocked in the sieve holes.
[0068] At the same time, the present invention uses PLA engineering plastics through 3DP technology for processing and manufacturing, with fast molding speed, degradable materials with minimal environmental harm, and cheap raw materials; in terms of seed placement, the amount of seed placement can be accurately controlled, and only a low-power motor is needed for operation, which not only reduces energy consumption, but also only needs to control the motor speed and the depth of the first material guide barrel 25 and the second material guide barrel 26 to adjust the sowing amount and spacing, etc., and the operation is very simple; because of the fast molding speed and low cost, it is also more conducive to the iterative design of the product; the product is designed in the form of multiple parts, and when sowing seeds of different sizes, it only needs to replace the seed sieve plate with the appropriate aperture size, and the compatibility is high.
