Description

Technical Field

[0001] This utility model belongs to the field of seeding equipment technology, and more specifically, relates to a directional equidistant auxiliary seeding device. Background Technology

[0002] As important sites for agricultural research, experimental crop fields, despite their relatively small size, place extremely high demands on crop cultivation techniques. Many experimental field research projects focus on specific crop varieties, often requiring very few rows or even single-row sowing, with extremely strict control over the spacing between crops within each row. Precise sowing spacing not only ensures that crops receive sufficient light, water, and nutrients during their growth process, avoiding competition and interference between them, but also facilitates researchers' systematic and comprehensive observation and study of crops at every stage, from seedling emergence and plant growth to final yield, thereby providing scientific and accurate guidance for agricultural production.

[0003] Currently, manual sowing is the most common method used in experimental field planting. Operators first roughly limit the spacing of crops using simple methods such as string lines, then sow seeds one by one manually, which is labor-intensive. Traditional mechanical sowing devices rely on rotating wheels to control the sowing spacing, making precise alignment with the seed holes impossible. When sowing from seedling trays, existing devices cannot adjust the sowing spacing, causing seeds to fall off-target and affecting the uniformity of sowing. Therefore, these issues prevent the precise, equidistant sowing that can be adjusted according to different sowing areas. Utility Model Content

[0004] In view of this, the present invention provides a directional equidistant auxiliary sowing device, which can solve the problem of not being able to achieve precise equidistant sowing according to different sowing areas.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a directional, evenly spaced auxiliary sowing device, comprising a frame, a sowing funnel, and a receiving screen. The frame has slides on both sides, and the two ends of the sowing funnel are connected to the slides via a screw drive assembly. A receiving screen is detachably installed at the bottom of the frame, and the receiving screen includes multiple sets of single-layer perforated plates with evenly spaced feeding holes. The sowing funnel is rotatably connected to a chuck via a rotating shaft, and a spring-loaded mechanism is provided between the chuck and the sowing funnel. A handle is fixedly connected to the top of the sowing funnel, and a partition is detachably installed inside the sowing funnel. Multiple sowing channels are formed at the bottom of the sowing funnel.

[0007] The technical effects of the directional equidistant auxiliary sowing device provided by this utility model are as follows: The sliding tracks on both sides of the frame, in conjunction with the screw transmission assembly, drive the sowing funnel to achieve directional equidistant displacement. By pulling the handle on the sowing funnel, the funnel rotates along the arc groove on the chuck. The sowing channel at the bottom, in conjunction with a single-layer perforated plate, allows seeds to fall into the corresponding sowing area. A rebound mechanism is provided to reset the sowing funnel, preventing seed leakage. By stacking multiple sets of single-layer perforated plates, the upper layer's obstruction of the lower layer's feeding mesh can alter the seed leakage gap, improving the device's adaptability and adjustability.

[0008] Based on the above technical solution, the directional equidistant auxiliary sowing device of this utility model can be further improved as follows:

[0009] The lead screw drive assembly includes a lead screw motor, the output end of which is fixedly connected to the lead screw, and the other end of the lead screw is movably connected to the side wall of the slide rail via a coupling seat.

[0010] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a lead screw motor to drive the lead screw to rotate, the sowing funnel can be displaced through the guide slides on both sides.

[0011] Furthermore, both ends of the sowing funnel are movably connected to the chuck via rotating shafts, and a guide slide is fixedly connected to the outer side of the chuck.

[0012] Furthermore, a through hole is provided in the middle of the guide slide, and a threaded structure adapted to the lead screw is provided inside the through hole.

[0013] Furthermore, guide protrusions are provided on the upper and lower sides of the guide slide, and guide grooves are provided on the inner side of the slide corresponding to the positions of the guide protrusions.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting the guide protrusion and the guide groove to cooperate, the displacement of the sowing funnel is more stable and the accuracy of displacement positioning is improved.

[0015] Furthermore, the rebound mechanism includes an arc-shaped groove on the inner side of the chuck, a pressure rod protruding on the outer side of the sowing funnel, and a compression spring.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting an arc-shaped groove, the sowing funnel is made to move along its interior through the pressure rod and contact the pressure spring, thereby realizing the flipping activity of the sowing funnel and aligning the sowing channel with the bottom receiving mesh plate.

[0017] Furthermore, the bottom end of the compression spring is fixedly connected to the bottom end of the arc-shaped groove, one end of the pressure rod is fixedly connected to the outside of the sowing funnel, and the other end moves along the arc-shaped groove and contacts the top end of the compression spring.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a compression spring, it can not only play a damping role in pulling the handle, but also drive the sowing funnel to reset in time, thus avoiding seed leakage inside the sowing funnel.

[0019] Furthermore, the top of the sowing funnel is provided with a movable cover plate, and the inner wall of the sowing funnel is provided with multiple sets of slots for installing the partition.

[0020] Furthermore, the bottom of the frame is fixedly surrounded by an L-shaped crossbar to form an inner mounting frame, and the inner side of the inner mounting frame is engaged with the receiving mesh plate through a slot.

[0021] The beneficial effect of adopting the above-mentioned improvement scheme is that a slot is set to install the single-layer sprue into the inner frame of the installation.

[0022] Furthermore, slopes are provided on both sides of the feeding mesh to facilitate seed falling.

[0023] The beneficial effect of adopting the above-mentioned improvement scheme is that by setting up a slope, it is easier for the seeds to fall.

[0024] Compared with existing technologies, the beneficial effects of the directional equidistant auxiliary sowing device provided by this utility model are as follows: The sliding tracks on both sides of the frame, in conjunction with the screw transmission assembly, drive the sowing funnel to achieve directional equidistant displacement. Pulling the handle on the sowing funnel causes it to flip along the arc-shaped groove on the chuck. The sowing channel at the bottom, in conjunction with a single-layer screen, allows seeds to fall into the corresponding sowing area. A rebound mechanism is provided to reset the sowing funnel, preventing seed leakage. By stacking multiple single-layer screens, the upper layer's obstruction of the lower layer's feeding mesh holes alters the seed leakage gap, improving the device's adaptability and adjustability. A screw motor drives the screw to rotate, allowing the sowing funnel to move via guide slides on both sides. The guide protrusions, in conjunction with guide grooves, make the sowing funnel's displacement more stable and improve the accuracy of positioning. The arc-shaped groove allows the sowing funnel to rotate via a pressure rod that contacts a compression spring, enabling the sowing funnel to flip and align the sowing channel with the bottom receiving mesh for precise sowing.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] like Figure 1-3 The image shows an embodiment of a directional, equally spaced auxiliary sowing device provided by this utility model. In this embodiment, it includes a frame 10, a sowing funnel 12, and a receiving mesh plate 13. Slides 11 are provided on both sides of the frame 10. The two ends of the sowing funnel 12 are connected to the slides 11 through a screw drive assembly. The receiving mesh plate 13 is detachably installed at the bottom of the frame 10. The receiving mesh plate 13 includes multiple sets of single-layer perforated plates 131. The single-layer perforated plates 131 are evenly provided with feeding mesh holes. The sowing funnel 12 is rotatably connected to a chuck 15 through a rotating shaft. A spring-loaded mechanism is provided between the chuck 15 and the sowing funnel 12. A handle 16 is fixedly connected to the top of the sowing funnel 12. A partition 17 is detachably installed inside the sowing funnel 12. Multiple sowing channels 18 are opened at the bottom of the sowing funnel 12.

[0033] When in use, move the frame 10 to the sowing area, or move the seedling tray below the frame 10, and add seeds into the sowing funnel 12. At this time, the sowing channel 18 is in an inclined state, and the seeds cannot leak out through the sowing channel 18. Then start the screw motor 19 to drive the sowing funnel 12 to achieve equidistant displacement. Each time you stop, pull the handle 16 to flip the sowing funnel 12. At this time, the sowing channel 18 is vertically downward, and the seeds flow out through the sowing channel 18 to the top of the receiving mesh plate 13, and fall into the corresponding sowing area through the feeding mesh holes on the single-layer sieve plate 131.

[0034] In the above technical solution, the lead screw transmission assembly includes a lead screw motor 19, the output end of the lead screw motor 19 is fixedly connected to the lead screw, and the other end of the lead screw is movably connected to the side wall of the slide rail 11 through a coupling seat.

[0035] In order to control the position of the guide slide 20 on the lead screw, the lead screw motor 19 has a built-in rotary encoder connected to the PLC controller. The rotary encoder feeds back the rotation information of the lead screw motor 19 to the PLC controller. The PLC controller controls the operation of the lead screw motor 19 according to the preset target position and the received feedback information, so as to achieve precise control of the position of the guide slide 20. In use, by inputting the spacing command, the PLC controller outputs a control signal to control the rotation of the lead screw motor 19, so that the sowing funnel 12 can achieve the effect of equidistant displacement.

[0036] Furthermore, in the above technical solution, the two ends of the sowing funnel 12 are movably connected to the chuck 15 via rotating shafts, and a guide slide 20 is fixedly connected to the outside of the chuck 15.

[0037] Furthermore, in the above technical solution, a through hole is provided in the middle of the guide slide 20, and a threaded structure adapted to the lead screw is provided inside the through hole.

[0038] Furthermore, in the above technical solution, guide protrusions are provided on the upper and lower sides of the guide slide 20, and guide grooves are provided on the inner side of the slide 11 corresponding to the positions of the guide protrusions.

[0039] Furthermore, in the above technical solution, the rebound mechanism includes an arc-shaped groove on the inner side of the chuck 15, a pressure rod protruding on the outer side of the sowing funnel 12, and a compression spring 21.

[0040] In order to achieve stable seed accumulation in the tilted state, the connection between the bottom and the side of the funnel and the opening is designed with an arc shape, and the central angle corresponding to the arc surface is between 90° and 120°.

[0041] Furthermore, in the above technical solution, the bottom end of the compression spring 21 is fixedly connected to the bottom end of the arc-shaped groove, one end of the pressure rod is fixedly connected to the outside of the sowing funnel 12, and the other end moves along the arc-shaped groove and contacts the top end of the compression spring 21.

[0042] Furthermore, in the above technical solution, the top of the sowing funnel 12 is provided with a movable cover plate, and the inner wall of the sowing funnel 12 is provided with multiple sets of slots for installing the partition plate 17.

[0043] When in use, the seed storage space inside the sowing funnel 12 can be adjusted according to different sowing areas. Inserting the partition 17 into the corresponding slot will achieve the sowing effect of the area and can deal with the sowing of the edge planting area.

[0044] Furthermore, in the above technical solution, the bottom of the frame 10 is fixedly surrounded by an L-shaped crossbar to form an inner frame for installation, and the inner side of the inner frame is engaged with the receiving mesh plate 13 through a slot.

[0045] To accommodate planting holes with different spacing, multiple layers of single-layer perforated plates 131 can be stacked, and the planting position can be adjusted by using the upper layer to block the lower layer.

[0046] Furthermore, in the above technical solution, slopes are provided on both sides of the feeding mesh to facilitate the falling of seeds.

[0047] Specifically, the principle of this utility model is as follows: When in use, the frame 10 is moved to the sowing area, or the seedling tray is moved below the frame 10, and seeds are added into the sowing funnel 12. At this time, the sowing channel 18 is in an inclined state, and the seeds cannot leak out through the sowing channel 18. Then, the screw motor 19 is started to drive the sowing funnel 12 to achieve equidistant displacement. Each time it stops, the sowing funnel 12 is flipped by pulling the handle 16. At this time, the sowing channel 18 is vertically downward, and the seeds flow out through the sowing channel 18 to the top of the receiving mesh plate 13, and fall into the corresponding sowing area through the feeding mesh holes on the single-layer sieve plate 131.
