Description

Technical Field

[0001] The utility model relates to the technical field of wheat planting, in particular to a slotting device for wheat planting that facilitates adjustment of planting spacing. Background Art

[0002] As a core grain crop in China, wheat has an extensive planting area, and its planting efficiency and quality are directly related to national grain yield security and supply stability. In the whole process of wheat planting, soil slotting is a key procedure that determines subsequent planting effectiveness — the spacing accuracy of slots directly affects the ventilation and light distribution among seedlings, the slot shape stability is related to nutrient absorption efficiency, and the operation efficiency determines the length of the planting cycle. These three factors jointly affect the final yield of wheat. Therefore, developing efficient and accurate slotting devices is core equipment support to ensure high-quality and high-yield wheat. However, currently available wheat planting slotting devices on the market still have problems to be solved urgently such as insufficient flexibility in spacing adjustment and limited operation adaptability;

[0003] For example, in the prior art, the "intelligent and precise wheat tillage and sowing row spacing automatic adjustment device" disclosed with application number CN202510967487.9, although it tries to optimize the spacing adjustment function through a specific structural design (it adopts a structure where a mounting base is slidably connected with a first chute, and a sliding table cooperates with a second chute, the tillage and sowing components are assembled on the surface of the sliding table, and at the same time, by means of an adjustment component with multiple sets of protrusions and a middle-shaped mounting slot, the mounting base can be pushed along the first chute to adjust the spacing between adjacent tillage and sowing components, and redundant mounting bases can be moved to the upper side of the machine body to meet the requirements of different sowing spacing), but the device has significant limitations in practical application: First, the structure is complex, involving multiple electrically controlled and mechanical components such as annular guide rails, electromagnets, and electric pushing cylinders. Failure of any component (such as jamming of the annular guide rail, loss of magnetism of the electromagnet, or sealing failure of the electric pushing cylinder) will directly cause the spacing adjustment function to fail, and the reliability is restricted by multiple links; Second, it is highly dependent on power, it needs to rely on electric drive and be adapted to special power equipment such as tractors. In remote plots without power supply or small scattered planting areas, it is difficult to meet actual operation requirements, and there are obvious restrictions on applicable scenarios;

[0004] Based on this, the present solution proposes "a slotting device for wheat planting that facilitates adjustment of planting spacing" to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a slotting device for wheat planting that facilitates adjustment of planting spacing, so as to solve the problem that existing devices on the market involve multiple electrically controlled and mechanical components and are not easy to maintain, which is proposed in the above background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grooving device for wheat planting that facilitates adjustment of planting spacing, comprising a support beam, limiting holes, bolt holes, adjusting blocks, and a seed placement interface;

[0007] An adjustment mechanism is provided on the side of the support beam. The adjustment mechanism includes an adjustment block, an adjustment screw, and a limiting block. The adjustment screw is installed on the side of the limiting block, the limiting block is installed inside the adjustment block, and the adjustment block is installed on the side of the support beam.

[0008] As a preferred technical solution of this utility model, the support beam is made of square steel pipe and has an I-shaped structure. Ten limiting holes are evenly distributed on the side surface of the support beam and placed on the same side of the support beam. Eight bolt holes are symmetrically distributed above and below the center line of the support beam.

[0009] The above technical solution utilizes a square steel tube structure in an I-shape for the support beam. This design ensures sufficient load-bearing strength to withstand the resistance from components such as the plow during wheat planting trenching, while also controlling the beam's weight to prevent excessive weight from burdening the device during movement or operation. Furthermore, ten evenly distributed limiting holes on the side surface of the support beam provide multiple adjustment positions for the adjusting blocks, flexibly adapting to different wheat varieties and planting densities. Eight symmetrically distributed bolt holes along the centerline of the support beam reinforce the connection between the support beam and other auxiliary components, preventing loosening due to vibration during operation and further enhancing the overall structural stability and operational reliability of the device.

[0010] As a preferred embodiment of this utility model, dust discharge holes are provided on both the left and right sides of the support beam, and the dust discharge holes are connected to both sides of the support beam.

[0011] By adopting the above technical solution, dust discharge holes are opened on both sides of the support beam and the dust discharge holes are connected to both sides of the support beam. This design can promptly discharge soil debris, dust and other impurities generated during the wheat planting trenching operation to the outside of the support beam, effectively preventing impurities from accumulating inside the support beam and preventing impurities from entering the connection between the adjusting block and the support beam or the adjusting mechanism such as the adjusting screw. This avoids the normal operation of the adjusting mechanism due to impurities blocking it, ensuring the smooth realization of the adjustment function. At the same time, it reduces the wear of impurities on the inner wall of the support beam and the adjusting components, extends the service life of the device, and also reduces the dust concentration in the working environment, reducing the impact on operators.

[0012] As a preferred technical solution of this utility model, a movable adjusting block is fitted on the outer side of the support beam. A U-shaped groove is opened on one side of the adjusting block, and an adjusting screw is threaded to the other side of the adjusting block. The adjusting screw has a T-shaped structure and is rotatably connected to the adjusting block.

[0013] The above technical solution involves mounting a movable adjusting block on the outer side of the support beam, with a U-shaped groove on one side of the adjusting block. This U-shaped groove fits tightly against the outer wall of the support beam, improving the stability of the adjusting block when sliding on the support beam and preventing it from shifting or wobbling during sliding, thus reducing the difficulty of the adjustment operation. The other side of the adjusting block is connected to a T-shaped adjusting screw, which not only fixes the position of the adjusting block through the threaded connection, ensuring that the adjusting block does not shift during operation, but also allows the operator to directly grip and rotate the T-shaped head without the need for additional tools such as wrenches. This simplifies the operation steps of the adjusting screw, allowing the operator to quickly fix and loosen the adjusting block, thus improving the adjustment efficiency.

[0014] As a preferred technical solution of this utility model, the adjusting block has a cylindrical protrusion fixed on its side, and the adjusting block is engaged and fixed with the support beam through the protrusion on its side and the limiting hole;

[0015] By adopting the above technical solution, a fixed cylindrical protrusion is set on the side of the adjusting block, so that the adjusting block can be locked in place with the limiting hole and the support beam through the protrusion. This locking structure can achieve precise positioning of the adjusting block, ensuring that the adjusting block is stably connected with the support beam after being adjusted to the target position. This avoids the position displacement of the adjusting block due to device vibration during the wheat planting trenching operation, and ensures that the trenching spacing meets the preset planting requirements. At the same time, the locking method does not require a complicated disassembly process. The operator only needs to loosen the adjusting screw to release the locking, which makes it easy to flexibly adjust the position of the adjusting block or increase or decrease the number of adjusting blocks according to planting needs, thus improving the flexibility of the device.

[0016] As a preferred technical solution of this utility model, the connecting arm is fixed by bolts on the side of the adjusting block, the connecting arm is U-shaped in general, and the plow head is fixed by bolts below the connecting arm;

[0017] The above technical solution uses bolts to fix the connecting arm on the side of the adjusting block. The connecting arm has a U-shaped structure, which effectively disperses the soil resistance on the plow head during grooving operations, reduces local stress concentration on the connecting arm, prevents the connecting arm from bending or breaking due to long-term stress, and extends the service life of the connecting arm. The design of fixing the plow head to the bottom of the connecting arm with bolts not only ensures a firm connection between the plow head and the connecting arm, ensuring that the plow head does not loosen or fall off during grooving and guaranteeing the stability of grooving depth and grooving shape, but also allows operators to easily disassemble and replace plow heads of different specifications or worn ones according to soil hardness, grooving depth requirements, etc., reducing the cost of component maintenance and replacement and improving the adaptability of the device.

[0018] As a preferred technical solution of this utility model, the seed-feeding interface is connected above the plow head, the seed-feeding interface has a flange interface structure, and a seed outlet hole is opened below the plow head, the seed outlet hole being connected to the seed-feeding interface;

[0019] The above technical solution features a seed-laying interface connected to the top of the plowshare, which is a flange-type interface. This flange interface provides excellent sealing and connection strength, allowing for tight connection with external seed delivery pipes or equipment. This effectively prevents seed leakage or spillage during delivery, reduces seed waste, and ensures accurate seed delivery. The seed outlet at the bottom of the plowshare connects to the seed-laying interface, enabling seeds to enter the plowshare through the seed-laying interface and fall directly into the prepared trenches while the plowshare is creating soil trenches. This allows for simultaneous trenching and sowing, simplifying the wheat planting process, reducing operator workload, and avoiding problems such as soil compaction and uneven seed coverage that may occur after trenching. This also helps improve the germination rate and growth consistency of wheat seeds.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This device uses a support beam as its core foundation, and structural optimization lays the basis for stable operation and flexible spacing adjustment. The support beam adopts a square steel pipe and I-beam structure, which ensures sufficient load-bearing strength to cope with grooving resistance while achieving lightweight design, facilitating device movement and operation. Ten evenly distributed limit holes on its side provide multiple position selections for the adjustment block, which can accurately adapt to the spacing requirements of different wheat planting densities. Eight symmetrical bolt holes above and below the center line enhance the stability of component connections and prevent loosening caused by operational vibrations. The dust exhaust holes connected on both sides can promptly discharge soil debris and dust, preventing impurities from accumulating and clogging the adjustment mechanism and wear parts. This ensures smooth spacing adjustment, extends the device's lifespan, and improves the working environment.

[0022] 2. The adjustment mechanism of the device is designed with convenience and precision in mind, significantly improving the efficiency and accuracy of spacing adjustment. The movable adjustment block fitted on the outside of the support beam fits tightly with the support beam through a U-shaped groove, ensuring stable sliding with low resistance. The T-shaped adjustment screw can be directly gripped and rotated without additional tools, making it easy and quick to fix or loosen the adjustment block, resulting in simple and efficient operation. At the same time, the cylindrical protrusion on the side of the adjustment block engages with the limiting hole to achieve precise positioning of the adjustment block, effectively preventing spacing deviation caused by operational vibration, ensuring that the grooving spacing meets the preset planting requirements, and satisfying the strict requirements for spacing accuracy in wheat planting.

[0023] 3. The structural design of the working components balances durability and adaptability, reducing maintenance costs and improving the versatility of the device. The U-shaped connecting arm, which is fixed to the side of the adjusting block by bolts, effectively disperses the soil resistance encountered by the plow during operation, reduces local stress concentration, and prevents the connecting arm from bending or breaking due to long-term stress, significantly extending its service life. Furthermore, the bolted connection between the connecting arm and the plow head allows operators to quickly disassemble and replace plow heads of different specifications or with wear according to actual needs such as soil hardness and trenching depth, reducing component maintenance and replacement costs and improving the device's adaptability to different planting scenarios.

[0024] 4. The device integrates trenching and sowing functions, simplifying the planting process and ensuring planting quality. The seed-dispensing interface above the plow head adopts a flange interface structure, which has strong sealing and stable connection, and can be tightly connected with external seed conveying equipment, effectively preventing seed leakage or spillage during seed conveying and reducing seed waste. The seed outlet below the plow head is directly connected to the seed-dispensing interface, allowing seeds to fall directly into the trench from the seed outlet while the device completes soil trenching with the plow head, realizing simultaneous trenching and sowing. This not only simplifies the wheat planting operation process and reduces the workload of operators, but also avoids problems such as soil compaction and uneven seed coverage depth that may occur when trenching is done before sowing, helping to improve the germination rate and growth consistency of wheat seeds.

[0034] 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.

[0035] Please see Figure 1-8 The present invention provides a grooving device for wheat planting that facilitates the adjustment of planting spacing; comprising a support beam 1, a limiting hole 2, a bolt hole 3, an adjusting block 4, a connecting arm 5, a plow head 6, an adjusting screw 7, a limiting block 8, a seed outlet hole 9, a dust discharge hole 10, and a seed release interface 11.

[0036] An adjustment mechanism is provided on the side of the support beam 1. The adjustment mechanism includes an adjustment block 4, an adjustment screw 7, and a limiting block 8. The adjustment screw 7 is installed on the side of the limiting block 8, the limiting block 8 is installed inside the adjustment block 4, and the adjustment block 4 is installed on the side of the support beam 1.

[0037] The support beam 1 is made of square steel pipe in an I-shape. Ten evenly distributed limiting holes 2 are located on the same side of its side surface, and eight symmetrically distributed bolt holes 3 are located on the upper and lower sides of the center line. The I-shaped square steel pipe structure ensures that the support beam 1 has sufficient load-bearing strength to stably withstand the resistance transmitted by components such as the plow head 6 during grooving operations, while also controlling its own weight to avoid increasing the burden on the device's movement or operation due to excessive structural weight. The ten evenly distributed limiting holes 2 provide multiple positions for adjusting the position of the adjusting block 4, which can flexibly adapt to the grooving spacing requirements of different wheat varieties and planting densities. The eight symmetrical bolt holes 3 can reinforce the connection between the support beam 1 and other auxiliary components, prevent the components from loosening due to operational vibration, and further improve the overall structural stability and operational reliability of the device.

[0038] Dust exhaust holes 10 are provided on both the left and right sides of the support beam 1, and the dust exhaust holes 10 connect the two sides of the support beam 1. The dust exhaust holes 10 connecting the two sides can promptly discharge soil debris, dust and other impurities generated during the grooving operation to the outside of the support beam 1, effectively preventing impurities from accumulating inside the support beam 1. This not only prevents impurities from entering the connection between the adjusting block 4 and the support beam 1, the adjusting screw 7 and other adjusting mechanisms, causing jamming, and ensuring smooth operation of the distance adjustment function, but also reduces the wear of impurities on the inner wall of the support beam 1 and the adjusting components, extending the service life of the device. At the same time, it can also reduce the dust concentration in the working environment and reduce the impact on operators.

[0039] A movable adjusting block 4 is fitted on the outer side of the support beam 1. One side of the adjusting block 4 has a U-shaped groove, and the other side is threaded to an adjusting screw 7 with a T-shaped structure. The adjusting screw 7 is rotatably connected to the adjusting block 4. The U-shaped groove of the adjusting block 4 can fit tightly against the outer wall of the support beam 1, improving the stability of the adjusting block 4 sliding on the support beam 1, avoiding deviation or shaking during sliding, and reducing the difficulty of the adjustment operation. The T-shaped adjusting screw 7 fixes the position of the adjusting block 4 through the threaded connection, ensuring that the adjusting block 4 does not shift during operation. Its T-shaped head is easy for the operator to hold and rotate directly without the need for additional tools such as wrenches, simplifying the operation steps of the adjusting screw 7, helping the operator to quickly complete the fixing and loosening of the adjusting block 4, and improving the adjustment efficiency.

[0040] The adjusting block 4 has a cylindrical protrusion fixed on its side. The adjusting block 4 engages with the limiting hole 2 through the side protrusion to achieve a locking and fixing with the support beam 1. The locking structure of the cylindrical protrusion and the limiting hole 2 can achieve precise positioning of the adjusting block 4, ensuring that the adjusting block 4 is stably connected with the support beam 1 after being adjusted to the target position. This avoids the position displacement of the adjusting block 4 caused by operation vibration and ensures that the slot spacing meets the preset planting requirements. At the same time, the locking and fixing method does not require a complicated disassembly process. The operator only needs to loosen the adjusting screw 7 to release the locking, which makes it easy to flexibly adjust the position of the adjusting block 4 or increase or decrease the number according to the planting needs, significantly improving the flexibility of the device.

[0041] The connecting arm 5 is fixed to the side of the adjusting block 4 by bolts. The connecting arm 5 has an overall U-shaped structure, and the plow head 6 is fixed to its bottom by bolts. The U-shaped structure of the connecting arm 5 can effectively disperse the soil resistance experienced by the plow head 6 during trenching operations, reduce local stress concentration in the connecting arm 5, prevent it from bending or breaking due to long-term stress, and extend the service life of the connecting arm 5. The bolt connection method not only ensures that the plow head 6 and the connecting arm 5 are firmly connected, ensuring that the plow head 6 does not loosen or fall off during trenching, and ensuring the stability of trenching depth and trench shape, but also makes it easy for operators to disassemble and replace plow heads 6 of different specifications or wear according to soil hardness and trenching depth requirements, reducing component maintenance and replacement costs and improving the adaptability of the device to different planting scenarios.

[0042] The plow head 6 is connected to a seed-laying interface 11, which adopts a flange interface structure. A seed outlet hole 9 is provided below the plow head 6, and the seed outlet hole 9 is connected to the seed-laying interface 11. The flange interface structure of the seed-laying interface 11 has good sealing performance and connection strength, and can be tightly connected to external seed conveying pipes or equipment, effectively preventing seed leakage or spillage during seed conveying, reducing seed waste, and ensuring the accuracy of seed delivery. The connection design between the seed outlet hole 9 and the seed-laying interface 11 allows the seed to enter the plow head 6 through the seed-laying interface 11 while the device completes soil trenching through the plow head 6, and then fall directly into the trench from the seed outlet hole 9, realizing simultaneous trenching and sowing. This simplifies the wheat planting operation process, reduces the workload of operators, and avoids problems such as soil compaction and uneven seed coverage depth that may occur when trenching is done before sowing, which is conducive to improving the germination rate and growth consistency of wheat seeds.

[0043] Working Principle: When using a grooving device for wheat planting that facilitates easy adjustment of planting spacing, the first step is to adjust the planting spacing. Based on the target wheat planting density, the operator first loosens the T-shaped adjusting screw 7 on the side of the adjusting block 4, releasing the fixing limit of the adjusting screw 7 on the adjusting block 4. At this time, the adjusting block 4 can slide along the outer wall of the support beam 1 through the U-shaped groove on its side, moving the adjusting block 4 to the position corresponding to the limiting hole 2 on the side of the support beam 1. Then, the cylindrical protrusion on the side of the adjusting block 4 engages with the limiting hole 2, achieving precise positioning of the adjusting block 4 and the support beam 1. Next, the adjusting screw 7 is tightened in the opposite direction. Through the threaded connection between the adjusting screw 7 and the adjusting block 4, and the auxiliary limiting of the limiting block 8, the adjusting block 4 is stably fixed on the support beam 1, completing the adjustment of a single set of grooving spacing. If multiple sets of grooving are required, the above steps can be repeated to increase or decrease the number of adjusting blocks 4 and adjust the spacing to adapt to different planting needs.

[0044] After adjustment, the auxiliary components of the device are reinforced by bolt holes 3 above and below the centerline of the support beam 1 to ensure the stability of the overall structure. Then, the external seed conveying equipment is sealed and connected to the seed release interface 11 of the flange structure above the plow head 6 to ensure that there is no leakage during the seed conveying process.

[0045] During operation, the device is moved by a traction mechanism or manually. The U-shaped connecting arm 5, which is fixed by bolts on the side of the adjusting block 4, drives the plow head 6 below to cut into the soil. The plow head 6 is used to open a uniform planting trough by utilizing its structural characteristics. At the same time, the external seed conveying equipment is started. Wheat seeds enter the internal channel of the plow head 6 through the seed release interface 11, and then fall precisely into the newly opened planting trough through the seed outlet hole 9 below the plow head 6. This allows the opening of the trough and the sowing to be completed simultaneously, avoiding soil compaction caused by prolonged exposure.

[0046] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
