Description

Technical Field

[0001] The present application relates to the technical field of agricultural sowing, and in particular to a pelletized pepper seed seeder. Background Art

[0002] There are strict quantity and spacing requirements for sowing crops such as peppers. The seeds need to be buried after sowing, and two to three seeds are sown in each hole. If too many seeds are sown in each hole, manual removal of seedlings is required in the later stage, which is time-consuming and labor-intensive. If too few seeds are sown in each hole, seedling shortages may occur. Therefore, the quantity and quality of sowing need to be strictly controlled during sowing. In the traditional sowing process, two people work together to sow, one digging holes in front and the other throwing seeds in the back. This method is labor-intensive and inefficient.

[0003] For large-scale sowing, agricultural machinery is usually used for mechanized operations, but for small-scale sowing needs, such as sowing in experimental fields, sowing is still done manually; for example, a handheld seeder known to the inventor includes a sowing bucket, a sowing rod and a conical nozzle. When in use, the conical nozzle is first inserted into the soil, and then a certain amount of seeds is manually thrown into the sowing bucket. The seeds fall into the conical nozzle through the sowing rod, and then the conical nozzle is opened to complete a sowing. Although this method only requires one person to complete the sowing operation, it still requires manual placement of seeds, and there is still a problem of low sowing efficiency. In addition, pelletized pepper seeds are easy to break during sowing, and the sowing spacing is difficult to accurately control.

[0004] The information disclosed in this background technology section is only used to deepen the understanding of the background technology of the present disclosure, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to those skilled in the art. Summary of the invention

[0005] In view of at least one of the above technical problems, the present disclosure provides a pelletized pepper seed seeder, which realizes quantitative seed sowing by driving the sowing mechanism to rotate intermittently through a lifting mechanism. A single person can complete the sowing efficiently, and the sowing mechanism is close to the ground, which can avoid the coating of the pelletized pepper seeds from breaking when sowing. In addition, a caliper is provided at the bottom of the sowing rod to set a fixed distance, which is convenient for controlling the sowing spacing and thus achieving high-quality sowing. This solves the problems of low sowing efficiency of existing handheld seeders, difficulty in controlling the sowing spacing, and easy breaking of the coating when used for sowing pelletized pepper seeds.

[0006] According to one aspect of the present disclosure, a pelletized pepper seed seeder is provided, comprising a hollow sowing rod, a sowing mechanism arranged at the middle and lower part of the sowing rod, a duckbill arranged at the bottom port of the sowing rod and capable of opening and closing, and a lifting mechanism connected to the duckbill in correspondence; the sowing mechanism comprises a sowing bucket relatively fixed to the outside of the sowing rod, a sowing tray arranged inside the sowing rod, and a dial wheel rotating synchronously with the sowing tray; a plurality of holes for receiving seeds discharged from the sowing bucket and temporarily storing the seeds are arranged at equal intervals on the side wall of the sowing tray; the lifting mechanism comprises a handle arranged at the top of the sowing rod, a lifting switch fixed relatively to the handle and used for controlling the opening and closing of the duckbill, a lifting rod for transmission connecting the lifting switch and the duckbill, and a paddle fixed on the lifting rod and transmission matching with the dial wheel in correspondence; the paddle is a limit hinge.

[0007] In some embodiments of the present disclosure, a ramp for passing seeds is provided at the corresponding connection between the sowing rod and the sowing bucket, and an outlet end of the ramp corresponds to the hole.

[0008] In some embodiments of the present disclosure, arc-shaped retaining rings corresponding to the outer edge contour of the sowing plate are provided on both sides of the sowing plate, and the radius difference between the inner edge of the arc-shaped retaining ring and the outer edge of the sowing plate is smaller than the minimum seed particle size.

[0009] In some embodiments of the present disclosure, at least one limiting ring is provided on the outer side of the sowing rod, and the lifting rod is inserted into the limiting ring.

[0010] In some embodiments of the present disclosure, a caliper perpendicular to the axial direction of the sowing rod is provided at the bottom of the sowing rod.

[0011] In some embodiments of the present disclosure, the thumbwheel includes thumbwheel blades whose number matches the number of the holes.

[0012] In some embodiments of the present disclosure, the paddle includes a fixed blade fixed relative to the lifting rod, and a movable blade hinged to the fixed blade and used to paddle the paddle wheel; the maximum angle between the fixed blade and the movable blade is 180 degrees; the rotation direction of the movable blade is different from the rotation direction of the paddle wheel.

[0013] In some embodiments of the present disclosure, the duckbill is a cross-shaped duckbill, and the duckbill includes a moving mouth and a fixed mouth fixed at the bottom end of the sowing rod and hinged to the moving mouth; the moving mouth is hinged to the lifting rod accordingly.

[0014] In some embodiments of the present disclosure, a buffer is provided at one end of the lifting rod close to the duckbill; the buffer is a buffer spring sleeved outside the lifting rod.

[0015] One or more technical solutions provided in the embodiments of the present application have at least any of the following technical effects or advantages:

[0016] 1. Since the paddle is a limit hinge, its movable blade is in a horizontal state when it rotates to the maximum angle and can only rotate above the horizontal line of the paddle. When the lifting rod drives the paddle to move upward, the paddle contacts the dial wheel and drives the dial wheel to rotate. Since the dial wheel has a certain preload force, when the paddle moves downward and contacts the dial wheel, the movable blade of the paddle can rotate upward to avoid driving the dial wheel to rotate in the opposite direction, thereby realizing unidirectional intermittent rotation of the dial wheel and the seeding disc, and realizing intermittent seeding.

[0017] 2. Since the coating of pelletized pepper seeds is easy to break, the sowing mechanism of the present application is arranged at the middle and lower part of the sowing rod, which is close to the ground, so as to avoid the pepper pelletized coated seeds from breaking due to falling too high, so as to ensure the sowing quality; the height of the sowing bucket is low, which is convenient for adding seeds into the sowing bucket, and the center of gravity of the seeder is low, making its operation more convenient and stable.

[0018] 3. A caliper extending to the front end is provided at the bottom of the sowing rod. The caliper length can be set according to the sowing spacing requirements. When sowing, the caliper can point out the next sowing position. There is no need to manually measure the sowing spacing, making it easier to control the sowing spacing, more convenient to operate, and higher sowing quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "vertical", "horizontal", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on this application. The "connection" and "coupling" involved in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0026] Unless otherwise specified, the components, structures, and mechanisms involved in the following embodiments are conventional commercially available products.

[0027] The embodiment of the present application provides a pelletized pepper seed seeder, which solves the problems in the prior art of low sowing efficiency, difficulty in controlling the sowing spacing, and easy breakage of the coating when sowing pelletized seeds.

[0028] This example discloses a pelletized pepper seed seeder, see Figure 1 , including a hollow sowing rod 1, a sowing mechanism arranged at the middle and lower part of the sowing rod 1, a duckbill 2 arranged at the bottom end of the sowing rod 1 and capable of opening and closing, and a lifting mechanism corresponding to the duckbill 2.

[0029] See also Figure 1 The sowing mechanism includes a sowing bucket 3 relatively fixed to the outside of the sowing rod 1, a sowing disc 4 arranged inside the sowing rod 1, and a dial wheel 6 that rotates synchronously with the sowing disc 4 through a pin shaft 5; the sowing bucket 3 is semi-funnel-shaped and is used to store seeds to be sown. The sowing bucket 3 is arranged in the middle and lower part of the sowing rod 1 to facilitate operators to add seeds to the sowing bucket 3, and make the center of gravity of the seeder lower, thereby making the operation of the seeder more stable and labor-saving.

[0030] See also Figure 3 A plurality of holes 7 for receiving the seeds from the sowing bucket 3 and temporarily storing the seeds are arranged at equal intervals on the circumferential side wall of the sowing disc 4. According to the diameter of the pelletized pepper seeds and the number of seeds to be sown, each hole 7 is designed to store 2 to 3 seeds; the sowing disc 4 is fixed to the inside of the sowing rod 1 by a pin 5 and is rotatably connected to the sowing rod 1. A friction washer is arranged at the corresponding connection between the pin 5 and the sowing rod 1 to apply a certain pre-tightening force to the pin to prevent the sowing disc and the dial wheel from rotating at will; the sowing disc 4 is arranged in the middle and lower part of the sowing rod 1, which is close to the ground. Since the coating of the pelletized pepper seeds is easy to break, the seeds fall from the lower sowing disc 4 during the sowing process, which can prevent the seed coating from being broken due to excessive distance, thereby ensuring the integrity of the seeds and improving their sowing quality.

[0031] See also Figure 3The paddle wheel 6 is fixedly connected to the other end of the pin shaft 5 , and the paddle wheel 6 includes a paddle wheel shaft 9 and paddle wheel blades 10 . The number of the paddle wheel blades 10 is consistent with the number of the holes 7 and is evenly distributed on the circumferential side wall of the paddle wheel shaft 9 .

[0032] See also Figure 4 A ramp 11 for passing seeds is provided at the corresponding connection between the sowing rod 1 and the sowing bucket 3, and the outlet end of the ramp 11 corresponds to the hole 7. The seeds can enter the hole 7 from the sowing bucket 3 through the ramp 11; the ramp 11 is funnel-shaped. Compared with the seeds directly entering in large quantities and accumulating on the top of the sowing tray 4, the arrangement of the ramp 11 makes it less likely for the seeds to be blocked, and the seeder vibrates during the sowing process, which facilitates the seeds to fall smoothly into the hole 7 of the sowing tray 4, thereby avoiding problems such as seed jamming and seed leakage.

[0033] See also Figure 4 An arc-shaped retaining ring 8 is also provided inside the sowing rod 1, which is sleeved on the outer side of the circumference of the sowing disk 4 and corresponds to the outer edge contour of the sowing disk 4. The radius difference between the inner edge of the arc-shaped retaining ring 8 and the outer edge of the sowing disk 4 is smaller than the minimum particle size of the seeds, and is used to block the seeds in the holes 7 to prevent the seeds from falling.

[0034] See also Figure 1 The lifting mechanism includes a handle 12 fixed at the top of the sowing rod 1, a lifting switch 13 arranged below the handle 12 and hinged to the handle 12, a lifting rod 14 for transmission connection between the lifting switch 13 and the duckbill 2, and a paddle fixed on the lifting rod 14 and correspondingly matched with the dial 6 for transmission; a reset spring is provided at the corresponding connection between the lifting switch 13 and the handle 12, so that the lifting switch 13 can automatically return to the original preset position after completing a sowing operation, and the reset spring makes the lifting switch 13 have a fixed maximum upward travel, so that when the lifting switch moves to the uppermost end, the paddle drives the dial and the sowing plate to rotate to the position corresponding to the hole and the ramp.

[0035] See also Figure 1 The duckbill 2 is a cross duckbill, which is convenient for opening the film on the land to complete sowing. The duckbill 2 includes a movable mouth and a fixed mouth fixed at the bottom end of the sowing rod and hinged with the movable mouth. The bottom end of the lifting rod 14 is hinged with the movable mouth accordingly. When the lifting switch 13 moves up, the lifting rod 14 moves up accordingly and drives the movable mouth to move, thereby opening the duckbill 2 to make the seeds fall into the soil; a buffer spring 17 is provided at one end of the lifting rod 14 corresponding to the movable mouth, so that the duckbill 2 is in a closed state when not in operation; since the diameter of the pelletized pepper seeds is very small, the moving stroke of the lifting switch 13, the lifting rod 14 and the movable mouth is also very small, which is convenient for completing the seed covering after sowing.

[0036] See also Figure 2The paddle is a limit hinge, which includes a fixed blade 15 fixed relatively to the lifting rod 14, and a movable blade 16 hinged corresponding to the fixed blade 15 and used to paddle the dial 6. The rotation angle of the movable blade 16 is 0-180°, and it can only rotate above the horizontal line of the paddle, and cannot rotate downward. The paddle of the seeder is in a horizontal state when the lifting rod 14 moves upward, and the movable blade 16 contacts the dial blade 10 and drives the dial 6 to rotate. When the lifting rod 14 moves downward, the movable blade 16 contacts the dial blade 10 because the pin shaft 5 has a certain pre-tightening force. Therefore, the movable blade 16 will rotate upward without driving the dial blade 10 to rotate, thereby avoiding the reverse rotation of the dial 6, thereby realizing the unidirectional rotation of the dial 6 and the seeding disc 4.

[0037] See also Figure 1 A plurality of limiting rings 18 are provided on the outside of the sowing rod 1, and the lifting rod 14 is passed through the limiting rings 18 to ensure that the lifting rod 14 is always within a certain range in the horizontal direction to avoid the situation where the paddle and the paddle wheel 6 do not correspond or are separated.

[0038] See also Figure 1 A caliper 19 perpendicular to the sowing rod 1 is also provided on the outer side of the bottom of the sowing rod 1. The length of the caliper 19 can be set according to the sowing spacing of the seeds to be sown. When sowing, the caliper 19 can point out the next sowing position in advance without manually measuring the sowing spacing, so that the sowing spacing can be better controlled, the operation is more convenient, and the sowing quality is higher.

[0039] The working process of the seeder is as follows: insert the seeder into the position to be sown, at which time the caliper has punctured the next sowing point, hold the lifting switch tightly, the lifting switch drives the lifting rod to move upward, and drives the paddle to move upward and open the duckbill, the paddle drives the dial wheel and the sowing disc to rotate, at which time the seeds in the downward holes on the sowing disc fall into the soil with the duckbill opened, in addition, the seeds in the ramp fall into the upward holes on the sowing disc to prepare for subsequent sowing, pull out the seeder and release the lifting switch, cover the seeds with soil, and complete a sowing operation.

[0040] Although some preferred embodiments of the present application have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the inventive concept. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
