Description

Technical Field

[0001] This utility model relates to the field of barley sowing spacing control technology, and in particular to a device for precise sowing spacing control of feed barley. Background Technology

[0002] Feed barley has a wide range of uses. First, it is an important feed source, accounting for approximately 65%–70% of global barley production. Its kernels are rich in protein (13%–15%), amino acids, vitamins, and trace elements, with a higher nutritional value than corn. However, it contains anti-nutritional factors such as β-glucan (4%–8%), requiring physical processing (such as crushing, puffing, and pelleting), chemical treatment (such as adding sodium hydroxide), or enzyme preparations (such as β-glucanase) to improve digestibility. Second, the stalks and whole plant of feed barley can be used for silage. The hay is high in protein and low in crude fiber, making it a high-quality forage commonly used in cattle, sheep, pigs, and fish farming. Furthermore, feed barley is also used in the brewing industry, serving as a core ingredient in beer production, accounting for over 75% of the total. This is due to its balanced protein and starch content, easy germination to produce enzymes, and the protective role of the husks in malting and wort filtration. Meanwhile, the malt from feed barley can also be used to make barley tea, maltose and other foods, while barley grass powder is exported for use in health foods.

[0003] In the existing technology, in order to improve the sowing efficiency, a seeder is generally used in the planting of barley for feed. The existing seeders are generally grooved wheel seeders. This type of seeder sows seeds through grooved wheels. This sowing method has a large seeding capacity, but the sowing accuracy is not high. When seeds get stuck with the grooved wheels, it is not easy to detect and clean them in time, which reduces the sowing efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a precision sowing spacing control device for barley for feed, which addresses the problem that while seeders use grooved wheels for sowing, this method results in a large seeding volume but low sowing accuracy. When seeds get stuck with the grooved wheels, it is not easy to detect and clean them in time, thus reducing sowing efficiency.

[0005] A precision sowing spacing control device for feed barley includes: a gantry frame, a support column fixedly connected to the lower part of the gantry frame, a drive shaft movably inserted into the inside of the support column, and wheels fixedly sleeved on both ends of the drive shaft.

[0006] A rotating shaft is movably mounted on the gantry frame. A transmission pulley is movably fitted on the surface of the rotating shaft and the transmission shaft. Multiple seeding discs are equidistantly fitted on the surface of the rotating shaft. A funnel is provided above the seeding discs, and a seeding tube is provided below one side of the seeding discs.

[0007] In one embodiment, supports are fixedly connected to the upper two sides of the overhead frame, and the two supports are respectively sleeved on the two end surfaces of the rotating shaft.

[0008] In one embodiment, support frames are fixedly connected to the upper two sides of the gantry frame, and multiple limiting frames are fixedly inserted inside the gantry frame, with the funnel and the seeding tube respectively supported above the multiple limiting frames.

[0009] In one embodiment, the plurality of funnels and the plurality of seeding tubes slide along the surfaces of the plurality of limiting frames, and the plurality of funnels and the plurality of seeding tubes are on the same vertical line.

[0010] In one embodiment, a plurality of limiting blocks are movably sleeved on the surface of the plurality of limiting frames, and the plurality of limiting blocks are respectively located on both sides of the plurality of funnels and the plurality of seeding tubes.

[0011] In one embodiment, baffles are fixedly connected to the lower two outer walls of the funnel, and the inner walls of the two baffles are movably fitted to the two outer walls of the seeding disc.

[0012] In one embodiment, the surface of the limiting frame is provided with millimeter-level scale markings, and the limiting block is fixedly connected to the limiting frame by a locking screw. By adjusting the position of the limiting block on the limiting frame, the lateral offset of the funnel and the sowing tube can be controlled synchronously.

[0013] Beneficial effects

[0014] 1. The device drives the transmission shaft through the rotation of the wheel, and transmits the power synchronously to the shaft through the transmission pulley. This drives the equally spaced seeding discs to rotate. Seeds flow into the seeding discs from the precision discharge port at the bottom of the funnel. Under the action of centrifugal force and gravity, the seeds are evenly filled into the holes of the seeding discs. As the seeding discs continue to rotate, the seeds are carried to the inlet of the seeding tube and fall into the field along the adjustable angle seeding tube under the action of gravity, thus completing the precision seeding.

[0015] 2. By adjusting the position of the limiting block on the limiting frame, the lateral offset of the funnel and the sowing tube can be controlled synchronously. The limiting frame surface is marked with scales, and combined with the precise fixation of the locking screw, the row spacing adjustment accuracy is ensured to be ±0.2mm. During operation, the nylon baffle maintains a dynamic seal with the side wall of the seed tray to prevent seed spillage. The cleaning scraper moves synchronously with the limiting block to continuously remove debris from the guide rail surface, ensuring the stability of the sliding mechanism under complex field conditions. This device achieves precise control of the sowing spacing of forage barley through the synergistic action of mechanical transmission and precision adjustment mechanism. Attached Figure Description

[0028] The following is combined with Figures 1-4 This invention describes a device for precisely controlling the sowing spacing of barley for feed.

[0029] In one embodiment, a precision sowing spacing control device for feed barley includes: a gantry frame 100 and a rotating shaft 103. A support column 200 is fixedly connected to the lower part of the gantry frame 100. A drive shaft 300 is movably inserted into the inside of the support column 200. Wheels 301 are fixedly sleeved on both ends of the drive shaft 300. The rotating shaft 103 is movably mounted on the gantry frame 100. A drive pulley 400 is movably sleeved on the surfaces of the rotating shaft 103 and the drive shaft 300. A plurality of seeding discs 500 are equidistantly sleeved on the surface of the rotating shaft 103. A funnel 600 is provided above the seeding discs 500. A sowing tube 700 is provided below one side of the seeding discs 500.

[0030] In this embodiment, the gantry frame 100 serves as the basic frame of the entire device. The support column 200 is fixedly connected to the bottom by high-strength bolts. The support column 200 has a hollow design inside and a drive shaft 300 is movably inserted into it. The two ends of the drive shaft 300 are fixedly fitted with wheels 301 by key connection. The wheels 301 have a wide tread design to enhance grip in soft soil and ensure that the device moves smoothly.

[0031] A rotating shaft 103 extends horizontally through the gantry frame 100. Both ends of the gantry frame 100 are movably mounted on it via bearings, ensuring flexible rotation. Power is transmitted between the rotating shaft 103 and the drive shaft 300 via a transmission pulley 400. The transmission pulley 400 uses a synchronous belt structure to ensure synchronized speed and high transmission efficiency. Multiple seeding discs 500 are equidistantly fitted onto the surface of the rotating shaft 103. Each seeding disc 500 undergoes precise dynamic balancing to minimize vibration during rotation. A funnel 600 is positioned above each seeding disc 500, with its bottom outlet precisely aligned with the inlet of the seeding disc 500 to ensure smooth seed flow. A sowing tube 700 is located below one side of each seeding disc 500. The sowing tube 700 features an adjustable angle design to accommodate different sowing depths. The entire device has a compact structure, with all components working collaboratively to achieve precise control of the sowing spacing for feed barley.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, supports 102 are fixedly connected to the upper two sides of the gantry frame 100. The two supports 102 are respectively sleeved on the two end surfaces of the rotating shaft 103. Support frames 101 are fixedly connected to the upper two sides of the gantry frame 100. Multiple limiting frames 104 are fixedly inserted into the inside of the gantry frame 100. The funnel 600 and the seeding tube 700 are supported above the multiple limiting frames 104 respectively.

[0033] In this embodiment, high-strength alloy steel supports 102 are fixedly connected to the upper two sides of the overhead crane frame 100 by welding. Each support 102 adopts a double-ear structure and is respectively sleeved on both ends of the rotating shaft 103 by two sets of tapered roller bearings. This design not only ensures that the rotating shaft 103 can withstand a maximum torsional load of 200 N·m, but also controls the axial movement within 0.05 mm through the bearing preload adjustment mechanism. Shock-absorbing rubber pads are added at the connection between the support 102 and the overhead crane frame 100 to effectively filter the vibration and impact generated during field operations.

[0034] Between the longitudinal beams on both sides above the support frame 101, the limiting frame 104 is fixedly connected by a truss structure. Each limiting frame 104 adopts a single column design, with the main body being a chromium-molybdenum alloy steel pipe with a diameter of 25mm and a hard anodized surface. The top of the limiting frame 104 supports the supporting funnel 600 and the seeding pipe 700 respectively.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, multiple funnels 600 and multiple seeding tubes 700 slide along the surfaces of multiple limiting frames 104 respectively. The multiple funnels 600 and multiple seeding tubes 700 are on the same vertical line. Multiple limiting blocks 105 are movably sleeved on the surfaces of multiple limiting frames 104. The multiple limiting blocks 105 are located on both sides of the multiple funnels 600 and multiple seeding tubes 700 respectively.

[0036] In this embodiment, multiple funnels 600 and seeding tubes 700 slide along the chromium-molybdenum alloy guide rail of the limiting frame 104. The surface of the guide rail is finely ground and forms a durable lubricating film with solid grease. The limiting block 105 adopts a split design, with the main body made of toughened nylon and an embedded copper-based graphite bushing. The millimeter-level scale laser-engraved on the surface of the limiting block 105 and the pointer indicator form a dual-redundant positioning system. With the spring pin limiting mechanism, the row spacing can be quickly switched. Cleaning scrapers are installed on both sides of the limiting block 105. The cleaning scrapers move synchronously with the limiting block 105 to effectively remove the soil and straw debris attached to the surface of the guide rail, ensuring that the sliding mechanism can maintain adjustment accuracy under complex field conditions.

[0037] like Figure 2 , Figure 3 and Figure 4 As shown, baffles 601 are fixedly connected to the outer walls on both sides below the funnel 600. The inner walls of the two baffles 601 are movably fitted to the outer walls on both sides of the seeding disc 500. The surface of the limiting frame 104 is marked with millimeter-level scale marks, and the limiting block 105 is fixedly connected to the limiting frame 104 by a locking screw. By adjusting the position of the limiting block 105 on the limiting frame 104, the lateral offset of the funnel 600 and the seeding tube 700 can be controlled synchronously.

[0038] In this embodiment, nylon baffles 601 are fixedly connected to the outer walls on both sides below the funnel 600 by countersunk screws. The working surface of the baffle 601 is coated with a 0.3mm thick polytetrafluoroethylene coating. The inner wall of the nylon baffle 601 maintains a dynamic gap of 0.2-0.5mm with the side wall of the seeding tray 500. This design ensures an effective seal when the seeds flow through the seeding tray 500 and avoids sparks generated by direct contact between metal parts. The bottom of the baffle 601 adopts a chamfered transition structure, which, together with the Teflon non-stick coating on the surface of the seeding tray 500, effectively reduces the resistance of the falling seeds and effectively prevents seed jamming. The surface of the limiting frame 104 is marked with millimeter-level graduations using laser etching process. The graduation line width is 0.15mm and the depth is 0.05mm. The surface is covered with a fluorescent coating to ensure visibility in low light conditions.

[0039] Working principle:

[0040] The device drives the transmission shaft 300 through the rotation of the wheel 301, and transmits the power synchronously to the rotating shaft 103 through the transmission pulley 400, which drives the equally spaced seeding discs 500 to rotate. Seeds flow into the seeding discs 500 from the precision discharge port at the bottom of the funnel 600. Under the action of centrifugal force and gravity, the seeds are evenly filled into the holes of the seeding discs 500. As the seeding discs 500 continue to rotate, the seeds are carried to the inlet of the sowing tube 700. Under the action of gravity, the seeds fall into the field along the adjustable angle sowing tube 700, completing the precision sowing.

[0041] By adjusting the position of the limiting block 105 on the limiting frame 104, the lateral offset of the funnel 600 and the seeding tube 700 can be controlled synchronously. The limiting frame 104 has scale markings on its surface. Combined with the precise fixing of the locking screw, the row spacing adjustment accuracy is ensured to be ±0.2mm. During operation, the nylon baffle 601 and the side wall of the seeding tray 500 maintain a dynamic seal to prevent seeds from spilling out.

[0042] The cleaning scraper moves synchronously with the limiting block 105, continuously removing debris from the guide rail surface and ensuring the stability of the sliding mechanism under complex field conditions. This device achieves precise control of the planting spacing of forage barley through the synergistic action of mechanical transmission and a precision adjustment mechanism.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
