Description

Technical Field

[0001] This utility model relates to the technical field of wheat seeding tools, and in particular to a single-grain seeding tool for wheat with equal row and plant spacing. Background Technology

[0002] Wheat, an annual or biennial herbaceous plant belonging to the genus Triticum of the Poaceae family, is an important food crop widely cultivated globally. Its grains are rich in protein, carbohydrates, and various minerals. After being ground into flour, it is often used to make bread, noodles, and other staple foods, occupying a key position in the human diet.

[0003] The equal-row, equal-plant-spacing single-seed wheat sowing tool is specifically designed for wheat sowing. Its core function is to enable precise sowing of individual wheat seeds at equal row and plant spacing. This sowing method ensures that each seed receives relatively uniform and suitable growing space in the soil, thereby ensuring that the wheat can fully absorb nutrients, light, and water during its growth process. This lays a solid foundation for cultivating robust wheat plants and improving wheat yield and quality.

[0004] However, existing wheat sowing tools use a grooved wheel seed metering method in practical applications. Seeds are discharged from the seed metering port by gravity or mechanical propulsion. Although some tools attempt to achieve uniform seed metering by adjusting the speed of the seed metering wheel to avoid overly dense seedling emergence, in actual operation, due to the limitations of the structural design and working principle of the seed metering components, it is difficult for seeds to remain stably in a single-seed state during discharge. This results in multiple seeds being discharged in clusters. This clustered sowing leads to uneven spacing between wheat seedlings after emergence, with some areas being too dense. This poses great difficulties for subsequent investigation and selection of superior individual plants, making it difficult to accurately determine the true growth potential and genetic characteristics of each wheat plant, and seriously affecting the efficiency and quality of wheat variety breeding. Utility Model Content

[0031] 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.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a single-seed wheat seeding tool with equal row spacing. The horizontal plate 1 serves as the main load-bearing component, supporting important components such as the seeding mechanism 2 and the upper structure. A horizontal plate 4 is provided at the bottom of the horizontal plate 1, and the two work together to form a stable basic frame, enhancing overall stability. The seeding mechanism 2 is provided at the top of the horizontal plate 1 for single-seed wheat seeding. A support mechanism 3 is provided at the rear of the horizontal plate 4 to provide stable support for the tool and to allow for stable placement of the tool in different terrains. The seeding mechanism 2 includes multiple seeding tubes 201 for conveying and distributing wheat seeds.

[0033] The bottoms of multiple seeding tubes 201 are fixedly connected to the top of horizontal plate 1 to ensure the seeding tubes 201 are installed stably and securely. The bottoms of multiple seeding tubes 201 pass through the tops of horizontal plate 1 and horizontal plate 2, allowing the seeds to fall smoothly into the soil and opening up the sowing channel. The lower front part of the multiple seeding tubes 201 is fixedly connected to a fixing plate 202, which provides an installation base for components such as the pull rod 204 and supports related parts. The top front of the multiple fixing plates 202 is provided with a circular groove 203, which provides a sliding track for the pull rod 204 and guides the pull rod 204 to slide. The pull rod 204 is slidably connected inside the multiple circular grooves 203, and the opening and closing of the seeding cover 208 is controlled by pulling. The seeding cover 208 is operated. The bottom rear side of the multiple seeding tubes 201 is fixedly connected to a seeding port 205, which is the seed sowing outlet and discharges the seeds.

[0034] Multiple seeding ports 205 are fixedly connected to their left and right sides by connecting blocks 206, providing rotational connection points for rotating plates 207. Each of the connecting blocks 206 has a corresponding rotating plate 207 rotatably connected to one side. Rotation of these blocks opens and closes the seeding cover 208, controlling its rotation. Each rotating plate 207 has a seeding cover 208 rotatably connected to its rear side, used to close or open the seeding ports 205, controlling the seeding timing. Each rotating plate 207 has a connecting block 206 fixedly connected to its front side by connecting blocks 206. The connecting plate 209 cooperates with the hook 211 on the pull rod 204 to transmit the pulling force. The right side of the multiple connecting plates 209 is provided with a hanging hole 210, which is connected to the hook 211 to transmit the pulling force. The hook 211 is used to pull the rotating plate 207. The bottom end of the multiple pull rods 204 is fixedly connected with a hook 211 to pull the connecting plate 209 and transmit the pulling force to open the playback cover 208. The upper front side of the middle playback tube 201 is fixedly connected with a fixing rod 214 to enhance the structural stability of the playback mechanism 2 and strengthen the overall structure.

[0035] Each of the multiple pull rods 204 is provided with a reset component 212 on the upper rear side, so that the pull rods 204 automatically reset after operation and automatically close the play cover 208. The reset component 212 includes multiple reinforcing plates 2121 to enhance the strength of the connection between the pull rods 204 and the springs 2122 and to reinforce the connection point. The front sides of the multiple reinforcing plates 2121 are respectively fixedly connected to the upper rear side of the corresponding pull rods 204 to provide a connection base for the springs 2122 and to install the springs 2122. The bottom of each of the multiple reinforcing plates 2121 is fixedly connected to a spring 2122, which uses elasticity to reset the pull rods 204 and provide reset power. The bottom of each of the multiple springs 2122 is respectively fixedly connected to the top of the corresponding fixing plate 202 to form a reset structure and fix one end of the spring 2122. Each of the multiple pull rods 204 is provided with a pulling component 213, which makes it convenient for the operator to pull multiple pull rods 204 at the same time and operate multiple play covers 208 simultaneously.

[0036] The pulling assembly 213 includes multiple L-shaped rods 2131, which connect the pull rod 204 and the crossbar 2132 to transmit pulling force. The bottom front end of each of the multiple L-shaped rods 2131 is fixedly connected to the top end of the corresponding pull rod 204, connecting the pull rod 204 to the pulling assembly 213. The top rear end of each of the multiple L-shaped rods 2131 is fixedly connected to the same crossbar 2132, connecting the multiple L-shaped rods 2131 into a whole, which can be pulled synchronously and linked together. The front side of the crossbar 2132 is fixedly connected to a pulling rod 2133, which facilitates the operator to apply force to pull and provides an operating handle.

[0037] Specifically, the wheat single-seed sowing tool with equal row and plant spacing has a basic frame consisting of horizontal plate 1 and horizontal plate 4, supporting the sowing mechanism 2 and the support mechanism 3. In the sowing mechanism 2, multiple sowing tubes 201 are evenly arranged, with their bottoms penetrating horizontal plate 1 and horizontal plate 4 to achieve equal row and plant spacing sowing. The fixing plate 202 provides sliding guidance for the pull rod 204 through the circular groove 203. The hook 211 cooperates with the hanging hole 210 of the connecting plate 209. Pulling the pull rod 204 can rotate the plate 204. 07. Rotate around the connecting block 206 to open the seeding cover 208 and complete the sowing. The reinforcing plate 2121 and spring 2122 of the reset component 212 ensure that the pull rod 204 is reset and the seeding cover 208 is closed. The L-shaped rod 2131, the crossbar 2132 and the pull rod 2133 of the pulling component 213 are linked to open multiple seeding covers 208 in one operation, so that wheat is sown in small areas with equal row and plant spacing, avoiding the clustering of several wheat plants, and facilitating the investigation and selection of superior individual plants.

[0038] Reference Figure 1 and Figure 5 The support mechanism 3 is used to ensure the stable support and flexible adjustment of the tool. The extension plate 301 is used to expand the support range and increase the support area of ​​the tool. The front sides of the two extension plates 301 are respectively fixedly connected to the rear left and right ends of the horizontal plate 4, connecting the support mechanism 3 to the main structure and fixing the position of the support mechanism 3. The top rear sides of the two extension plates 301 are provided with sliding grooves 302 to provide sliding tracks for the support plate 303 and guide the movement of the support plate 303. The support plate 303 is slidably connected inside the two sliding grooves 302, and the support position can be adjusted by sliding to change the position of the support point.

[0039] The bottom of each of the two support plates 303 is rotatably connected to a rotating block 304, which enables the base plate 305 to adapt to the ground angle and uneven ground. The bottom of each of the two rotating blocks 304 is fixedly connected to the base plate 305, which directly contacts the ground to provide support force and stabilize the support tool. The top of each of the two support plates 303 is fixedly connected to a limit plate 306 to prevent the support plates 303 from sliding out of the sliding groove 302 and to ensure structural safety. The rear side of each of the two support plates 303 is provided with an adjustment component 307 for adjusting the support height and angle and adjusting the support status.

[0040] The adjustment assembly 307 includes an adjustment bolt 3071 for fixing the position of the support plate 303 and locking the support position. The rear sides of the two extension plates 301 are rotatably connected to the adjustment bolt 3071, so that the adjustment bolt 3071 can be flexibly rotated and adjusted for convenient operation and adjustment. The rear sides of the two support plates 303 are provided with multiple adjustment holes 3072 to provide different adjustment levels and meet various adjustment needs.

[0041] Specifically, the sliding groove 302 at the top provides a sliding track for the support plate 303, allowing the support plate 303 to move back and forth within the sliding groove 302 according to terrain requirements and adjust its support position. The rotating block 304 rotatably connected to the bottom of the support plate 303 is connected to the base plate 305. This rotatable connection allows the base plate 305 to automatically rotate and adjust its angle when in contact with the ground, closely fitting uneven ground, evenly distributing the weight of the tool, and enhancing the stability of the tool placement. The limiting plate 306 at the top of the support plate 303 serves a safety protection function. To prevent the support plate 303 from coming out of the sliding groove 302 during sliding, ensuring the safety and reliability of the support structure, the adjusting bolt 3071 is screwed into or out of the adjusting hole 3072 on the rear side of the support plate 303. The design of multiple adjusting holes 3072 provides multiple adjustment options. By loosening the adjusting bolt 3071, the operator can slide the support plate 303 to the appropriate position and then screw the adjusting bolt 3071 into the corresponding adjusting hole 3072 to achieve precise adjustment of the support height and angle, meeting different terrain and different sowing needs.

[0042] Reference Figure 2 , Figure 3 and Figure 4Each of the multiple playback tubes 201 has a connecting block 2 5 fixedly connected to its front side, providing an installation base for the ring 6 and supporting the ring 6. The ring 6 is also fixedly connected to the front side of each of the multiple connecting blocks 2 5, cooperating with the L-shaped rod 2131 to provide sliding guidance and guide the movement trajectory of the L-shaped rod 2131. The multiple L-shaped rods 2131 are respectively slidably connected to the interior of their corresponding rings 6, restricting the movement direction of the L-shaped rods 2131 and ensuring their stable pulling of the pull rod 204, thus guaranteeing the stable operation of the pulling assembly 213. The rear ends of the two adjusting bolts 3071 penetrate the extension plate 301 and are rotatably connected to the interior of the corresponding adjusting hole 3072. By rotating the adjusting bolts 3071, the position of the support plate 303 can be fixed and adjusted. The system also has the function of locking the height of the support mechanism 3, matching the size of the adjusting bolt 3071 with the adjusting hole 3072 to ensure a tight connection after the adjusting bolt 3071 is screwed into the adjusting hole 3072, preventing the support plate 303 from loosening, and ensuring the stability of the support mechanism 3 after adjustment. Multiple hooks 211 are slidably connected to the interior of the corresponding hanging holes 210 to transmit the pulling force of the pull rod 204, thereby driving the rotating plate 207 to rotate and open the play cover 208, controlling the opening and closing of the play cover 208. The bottom of multiple limiting plates 306 are respectively attached to the top of the corresponding extension plate 301 to limit the sliding range of the support plate 303 in the sliding groove 302, preventing it from sliding out and detaching, and ensuring the structural integrity and safety of the support mechanism 3.

[0043] Specifically, the ring 6 is slidably connected to the L-shaped rod 2131, which serves as a guide and limiter, ensuring that the L-shaped rod 2131 slides smoothly along the predetermined direction during the pulling process, preventing it from shaking or deviating. After the adjusting bolt 3071 is screwed into the adjusting hole 3072, it can reliably fix the position of the support plate 303, preventing it from shifting due to vibration or external force during the sowing process. The hook 211 pulls the connecting plate 209 through the hanging hole 210, driving the rotating plate 207 to rotate, thereby realizing the opening and closing of the sowing cover 208.

[0044] Working principle: The seeding tool is moved to the area to be sown. The support mechanism 3 stably places the tool on the ground. Horizontal plate 1 and horizontal plate 4 form a stable support structure. When sowing begins, the operator holds the pull rod 2133 in the pulling assembly 213. The pull rod 2133 is connected to the horizontal bar 2132, which is in turn fixed to multiple L-shaped rods 2131. The bottom front end of each L-shaped rod 2131 is connected to a pull rod 204. When the pull rod 2133 is pulled upwards, it causes multiple pull rods 204 to slide upwards within the circular groove 203. During the upward sliding of the pull rods 204, the hook 211 at its bottom pulls the connecting plate 209. The connecting plate 209 is fixedly connected to the rotating plate 207, which is rotatably connected to the connecting block 206. Therefore, when the hook 211 pulls the connecting plate 209, it causes the rotating plate 207 to rotate... When the connecting block 206 rotates, it causes the seeding cover 208 connected to the rear of the rotating plate 207 to open, exposing the seeding port 205. At this time, wheat seeds are put into the top of the seeding tube 201. The seeds will slide down along the inside of the seeding tube 201 and fall into the soil through the opened seeding port 205. After the seeds are sown, the operator releases the pull rod 2133. At this time, the reset component 212 starts to function. One end of the spring 2122 in the reset component 212 is connected to the bottom of the reinforcing plate 2121, and the other end is fixed to the top of the fixing plate 202. The reinforcing plate 2121 is fixed to the pull rod 204. After the pull rod 2133 is released, the spring 2122 returns to its deformation and pulls the pull rod 204 downward. The hook 211 drives the connecting plate 209 to make the rotating plate 207 rotate in the opposite direction, closing the seeding cover 208 again, completing one single seeding operation.

[0045] The operator first loosens the adjusting bolt 3071 in the adjusting assembly 307. The adjusting bolt 3071, through its rotatable connection with the extension plate 301, can be screwed into or out of the adjusting hole 3072 on the rear side of the support plate 303. The design of the adjusting hole 3072 allows for multiple adjustment levels to adapt to different terrains and sowing needs. The bottom of the support plate 303 is connected to the base plate 305 through the rotating block 304. This rotatable connection allows the base plate 305 to rotate freely on the horizontal plane, thereby adapting to uneven ground. When the tool is placed on the ground, the base plate 305 will automatically adjust its angle to ensure full contact with the ground and provide stable support. The function of the limiting plate 306 is to prevent the support plate 303 from coming out of the sliding groove 302, ensuring the safety and reliability of the mechanism. During the adjustment process, the limiting plate 306 always maintains contact with the extension plate 301, limiting the maximum sliding stroke of the support plate 303.

[0046] 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.
