Description

Technical Field

[0001] This utility model relates to the field of seeders, and in particular to a row-type hand-held seeder. Background Technology

[0002] Currently, the walk-behind seeder is a small, portable agricultural machine, generally composed of a seed box, a seeding wheel, a push rod, and a seeding mechanism. The seeding wheel can be rolled to make the seeding nozzle on the seeding wheel sow seeds. It is mainly used for sowing grain crops such as wheat, rice, corn, millet, and sorghum.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art:

[0004] In existing technologies, most walk-behind seeders use a single seeding wheel design, which makes it difficult to ensure the seeding width between adjacent rows during actual use, resulting in poor seeding uniformity and increased labor intensity and time. In addition, while it is possible to achieve synchronous seeding by directly combining multiple walk-behind seeders in a fixed manner to improve seeding uniformity, it is not convenient to adjust the spacing between multiple walk-behind seeders because different crops require different spacing for growth.

[0005] Therefore, those skilled in the art have provided a row-type hand-held seeder to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a row-type hand-held seeder that can achieve simultaneous sowing of multiple rows to improve the uniformity of sowing. It also allows for adjustment of the sowing row width, thereby improving its adaptability to sowing of various crops with different growth space requirements.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A chain-type walk-behind seeder includes multiple seed bins and threaded rods. Each of the seed bins has a threaded sleeve rotatably disposed at the center of the front end face of its outer wall. Each of the seed bins has a limiting groove penetrating through the center of the rear end face of its outer wall. Each of the seed bins has a second discharge port penetrating through the center of its lower end. Each of the seed bins has a seeding wheel rotatably sleeved on its outer wall. Each seeding wheel has multiple fixing plates fixedly disposed on its outer wall. Each seeding wheel has a third discharge port penetrating through the center of its inner wall.

[0009] Each of the multiple fixed plates is provided with a feeding mechanism at the center of its upper surface. Each feeding mechanism includes a discharge nozzle and a fixed tube. Each of the multiple discharge nozzles has a flap hinged to one side of its inner wall. Each of the multiple fixed tubes has a rotating shaft rotatably installed inside. Each of the multiple rotating shafts has a fixed rod fixedly installed at the center of its front end face. Each of the multiple fixed rods has a torsion spring movably sleeved at one end of its outer wall. Each of the threaded rods has a handle fixedly installed at both ends.

[0010] Furthermore, the plurality of discharge nozzles are respectively fixedly disposed at the center of the upper surface of the plurality of fixed plates, the plurality of rotating shafts are respectively rotatably disposed on one side of the front end surface of the outer wall of the plurality of discharge nozzles, the plurality of rotating shafts are respectively fixedly connected to one end of the hinge point of the plurality of flip plates, and one end of the plurality of fixed rods are respectively fixedly connected to the front end surface of the outer wall of the plurality of seeding wheels.

[0011] Furthermore, a first discharge port is provided through the center of the upper surface of each of the plurality of fixed plates, and the plurality of third discharge ports are respectively located on the same straight line as the plurality of first discharge ports.

[0012] Furthermore, the threaded rod slides through multiple limiting grooves, and multiple threaded sleeves are threadedly sleeved on the outer wall of the threaded rod, with the thread helix angle of the threaded rod being less than or equal to the friction angle.

[0013] Furthermore, the threaded rod has sliding grooves at both the upper and lower ends of its outer wall, and protrusions are fixedly provided at both the upper and lower ends of the inner walls of the multiple limiting grooves, with the multiple protrusions slidably disposed in the two sliding grooves respectively.

[0014] Furthermore, each of the seed material bins has a feeding pipe fixedly embedded in the upper surface of its outer wall, and the interior of each of the seed material bins is hollow.

[0015] Furthermore, both ends of the plurality of torsion springs are respectively fixedly connected to the outer wall of the fixed rod and the rotating shaft located in the same feeding mechanism.

[0016] This utility model has the following beneficial effects:

[0017] 1. The present invention proposes a row-type hand-held seeder, which connects multiple seed bins in parallel through threaded rods, so that multiple seeding wheels can be driven to rotate simultaneously when the handrail is pushed. The material feeding mechanism on the outer wall of the multiple seeding wheels enables simultaneous sowing of multiple rows, which improves the uniformity of multi-row sowing and significantly reduces the labor intensity and time of sowing on the same area of ​​land.

[0018] 2. The present invention proposes a row-type hand-held seeder in which multiple seed bins are slidably mounted on the outer wall of a threaded rod. The threaded rod restricts the rotation of the multiple seed bins. At this time, rotating the threaded sleeve block at the front end of the seed bin allows it to rotate on the outer wall of the threaded rod and move the seed bin to one side. This allows the spacing between the multiple seed bins to be adjusted, thereby making the spacing between the multiple seeding wheels adjustable. Thus, when sowing different crops, the row width of the multiple seeding wheels can be flexibly adjusted according to the space requirements of different crops during growth.

Detailed Implementation

[0026] 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.

[0027] Reference Figures 1 to 5 One embodiment provided by this utility model:

[0028] A series of hand-held seeders includes multiple seed bins 2 and threaded rods 11. Each seed bin 2 has a threaded sleeve 7 rotatably installed at the center of the front end face of its outer wall. Each seed bin 2 has a limiting groove 12 penetrating through the center of the rear end face of its outer wall. Each seed bin 2 has a second discharge port 9 penetrating through the center of the lower end of its outer wall. Each seed bin 2 has a seeding wheel 3 rotatably fitted onto its outer wall. Each seeding wheel 3 has multiple fixing plates 4 fixedly installed on its outer wall. Each seeding wheel 3 has a third discharge port 10 penetrating through the center of its inner wall.

[0029] Each of the multiple fixed plates 4 has a feeding mechanism 5 at the center of its upper end face. Each feeding mechanism 5 includes a discharge nozzle 501 and a fixed tube 504. Each of the multiple discharge nozzles 501 has a flap 502 hinged to one side of its inner wall. Each of the multiple fixed tubes 504 has a rotating shaft 503 rotatably mounted inside it. Each of the multiple rotating shafts 503 has a fixed rod 506 fixedly mounted at the center of its front end face. Each of the multiple fixed rods 506 has a torsion spring 505 movably sleeved at one end of its outer wall. Each of the threaded rods 11 has a handle 1 fixedly mounted at both ends.

[0030] Specifically, the push handle 1 can simultaneously drive multiple seeding wheels 3 to perform seeding operations, thereby improving seeding efficiency and uniformity. By rotating the threaded sleeve block 7, the seed hopper 2 can slide on the threaded rod 11, thereby adjusting the spacing between the multiple seeding wheels 3. When sowing different crops, the spacing between multiple rows of seeds can be adjusted according to the space required for the growth of different crops. The feeding mechanism 5 is fixed by the fixing plate 4 on the seeding wheel 3. Seeds can enter the second discharge port 9 and the third discharge port 10 through the seed hopper 2, and finally be fed and sown along the feeding mechanism 5.

[0031] Reference Figure 5 Multiple discharge nozzles 501 are fixedly installed at the center of the upper end face of multiple fixed plates 4. Multiple rotating shafts 503 are rotatably installed on one side of the front end face of the outer wall of multiple discharge nozzles 501. Multiple rotating shafts 503 are axially fixedly connected to one end of the hinge point of multiple flaps 502. One end of multiple fixed rods 506 is fixedly connected to the front end face of the outer wall of multiple seeding wheels 3.

[0032] Specifically, when the feeding mechanism 5 is embedded in the soil, the seeding wheel 3 drives the feeding mechanism 5 to rotate, causing the flap 502 to flip to one side under the action of soil resistance. The flap 502 can drive the rotating shaft 503 to rotate in the fixed tube 504 and drive the torsion spring 505 to twist. At this time, the seeds in the corresponding third discharge port 10 can fall into the soil along the first discharge port 8 in the corresponding position of the flap 502 to achieve the sowing effect. Continue to roll the seeding wheel 3 to make the feeding mechanism 5 leave the soil. At this time, the rotating shaft 503 flips under the action of the torsion spring 505 and drives the flap 502 to close, thereby preventing the seeds from spilling out.

[0033] Reference Figure 3 , Figure 4 Each of the multiple fixed plates 4 has a first discharge port 8 through the center of its upper surface, and multiple third discharge ports 10 are located on the same straight line as the multiple first discharge ports 8.

[0034] Specifically, after the seeds exit the seed hopper 2 through the second discharge port 9, they can be sown through the third discharge port 10 and the first discharge port 8.

[0035] Reference Figure 1 , Figure 2 , Figure 5 The threaded rod 11 slides through multiple limiting grooves 12, and multiple threaded sleeves 7 are threadedly sleeved on the outer wall of the threaded rod 11. The thread helix angle of the threaded rod 11 is less than or equal to the friction angle.

[0036] Specifically, rotating the threaded sleeve 7 causes it to rotate on the surface of the threaded rod 11 and drives the seed hopper 2 to slide to one side. At the same time, since the thread helix angle of the threaded rod 11 is smaller than the friction angle, it can achieve a certain degree of self-locking effect on the combination of the threaded rod 11 and the threaded sleeve 7, preventing the threaded sleeve 7 from rotating due to vibration and thus affecting the fixing effect of the seed hopper 2.

[0037] Reference Figure 5 The threaded rod 11 has sliding grooves at both the upper and lower ends of its outer wall, and multiple limiting grooves 12 have protrusions fixedly installed at both the upper and lower ends of their inner walls. The multiple protrusions are slidably installed in the two sliding grooves respectively.

[0038] Specifically, the sliding of the protrusion within the groove restricts the rotation of the seed hopper 2, thereby allowing the seed hopper 2 to slide on the surface of the threaded rod 11 when the threaded sleeve 7 is rotated, thus enabling the adjustment of the spacing between the multiple seeding wheels 3.

[0039] Reference Figure 2 , Figure 4 Each of the multiple seed hoppers 2 has a feeding pipe 6 fixedly embedded in the upper surface of its outer wall, and the interior of each of the multiple seed hoppers 2 is hollow.

[0040] Specifically, seeds are fed into the seed hopper 2 through the feed pipe 6, so that when the second discharge port 9 at the lower end of the outer wall of the seed hopper 2 and one of the third discharge ports 10 are on the same vertical line, the seeds can fall into the third discharge port 10 along the second discharge port 9.

[0041] Reference Figure 3 Multiple torsion springs 505 are fixedly connected at both ends to the outer wall of the fixed rod 506 and the rotating shaft 503 located in the same feeding mechanism 5.

[0042] Specifically, the flap 502 flips and drives the rotating shaft 503 to rotate, which in turn drives the torsion spring 505 to rotate and compress. When the flap 502 is removed from the soil, the elastic force of the torsion spring 505 drives the rotating shaft 503 to reverse, thereby enabling the flap 502 to close.

[0043] Working principle: Multiple seed bins 2 are connected in parallel via threaded rod 11, so that when the handle 1 is pushed, multiple sowing wheels 3 can be driven to rotate synchronously, thereby achieving multi-row synchronous sowing. This improves the uniformity of sowing while saving labor intensity and time, thus increasing sowing efficiency. At the same time, by using the sliding groove on the threaded rod 11 and the protrusion in the limiting groove 12 to restrict the rotation of the seed bins 2, the threaded sleeve block 7 can be rotated, which can drive the seed bins 2 to slide along the threaded rod 11, thereby achieving the effect of adjusting the spacing between multiple sowing wheels 3. When sowing seeds of different crops, the sowing row width can be flexibly adjusted according to the growth space requirements of different crops.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
