Abstract

This invention relates to the field of agricultural machinery technology and discloses a rotary tiller seeder, comprising a housing and connecting wheels. The connecting wheels are fixedly connected to the surface of the housing. Two transmission housings are symmetrically fixedly connected to both sides of the housing. Pressing wheels are rotatably connected to the opposite surfaces of the two transmission housings. A positioning rod is pushed by a slotted plate, causing seeds to leak from inside the pressing wheel and fall onto the cultivated land.

Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a rotary tiller and seeder. Background Technology

[0002] Rotary tillers are tillage machines used in conjunction with tractors to perform tillage and harrowing operations. They are widely used due to their strong soil-breaking ability and ability to flatten the soil surface after tillage. However, when existing rotary tillers break up the soil, grass roots in the soil become entangled on the blades, which can slow down or stop the blades from rotating. This reduces the overall tillage efficiency of the seeder. The operator needs to stop and clean the blades before continuing tillage, which causes unnecessary interruptions and wastes time. Grass roots entangled on the blades can easily damage the machinery. At the same time, when sowing, the presence of grass roots or weeds in the soil can hinder the seeds from falling into the already tilled soil. This requires the tilled soil to be sown again after the rotary tillage and sowing are completed, which requires the operator to repeat this step.

[0003] Newly tilled soil may lack sufficient nutrients for plant absorption and growth. Continuous use of rotary tillers without fertilization may lead to the depletion of nutrients in the soil. Soil is the foundation of plant growth. Continuously stripping plants of the nutrients they need without replenishing them with sufficient fertilizer will cause the soil quality to decline, becoming barren and unsuitable for planting crops.

[0004] Existing rotary tillers typically operate by breaking through the soil and sowing seeds along a straight line. Because the planting path is a single straight line, the soil is continuously and singularly utilized, leading to excessive consumption of nutrients such as nitrogen, phosphorus, and potassium. Consequently, other areas are used little or not at all. This reduces the soil's resilience to drought, increases the risk of soil-borne diseases and pests, and causes crop roots to concentrate in specific areas, reducing the space and resource supply for roots. This can trigger root competition among plants, affecting plant growth and development.

[0005] Therefore, a rotary tillage seeder is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a rotary tillage seeder to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rotary tillage seeder, comprising a housing and connecting wheels, the connecting wheels being fixedly connected to the surface of the housing, two transmission housings being symmetrically fixedly connected to both sides of the housing, and a pressing wheel being rotatably connected to the opposite surfaces of the two transmission housings, a transmission shaft being fixedly connected to both ends of the pressing wheel, and rollers being fixedly connected to both ends of the transmission shaft, a seeding box being inserted into the top of the housing, and symmetrically opened spreading holes at the bottom of the inner wall of the seeding box, a transmission component for driving the overall device transmission being provided inside the housing, a seeding component for compacting and weeding the field soil and sowing crop seeds being provided inside the housing, and a spreading component for spreading fertilizer on the soil being provided inside the housing;

[0010] Preferably, the transmission assembly further includes a helical gear 1, which is fixedly connected to the middle of the rotating shaft 1.

The bottom of the spur gear 1 meshes with a spur gear 2. A helical gear 2 is fixedly connected to the top of the spur gear 1. The helical gear 2 meshes with the helical gear 1.

[0011] Preferably, the sowing assembly further includes a fixing plate, which is fixedly connected to the bottom of the spur gear II. A rotating shaft II is fixedly connected to the bottom of the fixing plate. A slotted plate is fitted onto the surface of the rotating shaft II. A nut is fixedly connected to the bottom of the rotating shaft II. Fixing blocks are symmetrically fixedly connected to the middle of both sides of the slotted plate. Two fixing blocks are provided. A positioning rod is fixedly connected to the side of each fixing block away from the nut. Two sliding grooves are symmetrically opened at the bottom of the sowing box and at the top of the positioning rods. Spring I is fixedly connected to the corresponding end of each sliding groove. Two spring I are provided. A ladder is fixedly connected to the end of each spring I away from the center of the sowing box. Two trapezoidal sliders are fixedly connected to the end of the positioning rod away from the center of the feeding box. Two fixed housings are symmetrically fixedly connected to the side of the box near the connecting wheel. Telescopic rods are fixedly connected to the top of the inner wall of each of the two fixed housings. Two limiting blocks are fixedly connected to the bottom of each of the two telescopic rods. Two trapezoidal sliders are fixedly connected to the corresponding surfaces of the two limiting blocks. Each trapezoidal slider has a second opening on its surface. Each trapezoidal slider has a first opening on its surface. Each trapezoidal slider has a leak pipe fixedly connected to its bottom. Each leak pipe has a pressing column fixedly connected to its bottom. Each pressing column has a third opening inside its interior.

[0012] Preferably, the spreading assembly includes a fertilizer spreading box, which is inserted into the inside of the box body. The bottom of the inner wall of the fertilizer spreading box has a fertilizer spreading hole, and the bottom of the outer wall of the fertilizer spreading box has a transmission groove. A spring is fixedly connected to one end of the transmission groove near the spreading box, and an L-shaped plate is fixedly connected to the other end of the spring away from the spreading box. The L-shaped plate is slidably connected to the transmission groove, and rotary tillage blades are equidistantly arranged in a ring around the middle of the compaction wheel.

[0013] Preferably, the shape of the third leak is adapted to the shapes of the second leak, the first leak, and the material dispensing hole, so as to achieve a tight fit between the third leak and the second, the first leak, and the material dispensing hole.

[0014] Preferably, the L-shaped plate has holes on its surface, the shape of which matches the shape of the fertilizer spreading hole, so as to achieve a tight fit between the L-shaped plate and the fertilizer spreading hole.

[0015] Preferably, the surface of the compaction column is provided with five metal blades with triangular cross-sections at equal intervals, which serve to remove weeds from the soil surface and inside.

[0016] Preferably, the connecting wheel is driven to be mounted on an external traction machine, serving to transmit power.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By using the pressing column during sowing to break up the soil and cut off the grass roots, the problem of grass roots in the soil getting tangled on the cutter shaft during sowing, causing the cutter shaft to slow down or stop rotating, is avoided. This not only improves the overall tillage efficiency of the rotary tiller, but also improves the soil's aeration, permeability, and nutrient supply capacity by cutting off the grass roots, making the soil more conducive to crop growth and nutrient absorption, thereby reducing subsequent maintenance work. At the same time, by cutting off the grass roots and weeds, the grass roots in the soil are prevented from obstructing the seeds from falling into the tilled soil during sowing, thus improving the accuracy of seed landing in the tilled soil during sowing.

[0019] 2. The positioning rod is pushed by the slot plate, causing the seeds to leak out from inside the pressing column and fall onto the cultivated land. This avoids the crops growing in a concentrated area, solving the problem of poor growth caused by insufficient nutrients due to concentrated crop growth. This structure allows for more even growth of plants by staggering the planting positions, preventing crops from blocking each other's light and causing poor growth. It also increases the space between harvesting crops, making it easier for manual operation or mechanical equipment to enter during harvesting. At the same time, staggered planting can also effectively reduce the risk of disease and pest transmission, helping crops maintain healthy growth.

[0020] 3. By using rotary tillers to push the L-shaped plate, fertilizer leaks from inside the L-shaped plate and falls onto the cultivated land. This avoids the situation where newly cultivated soil lacks the nutrients necessary for crop growth, leading to crop depletion. This structure, by spreading fertilizer during the sowing process, not only achieves the rational use of resources but also improves crop growth conditions, thereby increasing yield and further realizing the efficient use of farmland. At the same time, it improves the soil quality, making the soil richer in the nutrients needed for crop growth and enabling sustainable use. Attached Figure Description

[0040] The sowing assembly 3 also includes a fixing plate 33, which is fixedly connected to the bottom of the second spur gear 32. A second rotating shaft 35 is fixedly connected to the bottom of the fixing plate 33. A slotted plate 34 is fitted onto the surface of the second rotating shaft 35. A nut 36 is fixedly connected to the bottom of the second rotating shaft 35. Two fixing blocks 37 are symmetrically fixedly connected to the middle of both sides of the slotted plate 34. A positioning rod 38 is fixedly connected to the side of each fixing block 37 away from the nut 36. Two sliding grooves 39 are symmetrically opened at the bottom of the sowing box 17 and at the top of the positioning rod 38. A spring 312 is fixedly connected to the corresponding end of each sliding groove 39. Two springs 312 are provided. A trapezoidal slider 310 is fixedly connected to the end of each spring 312 away from the center of the sowing box 17. The two trapezoidal sliders 310 are fixedly connected to the end of the positioning rod 38 away from the center of the sowing box 17. Two fixed housings 3 are symmetrically fixedly connected to the side of the box 11 near the connecting wheel 12. 13. Telescopic rods 314 are fixedly connected to the top of the inner walls of both fixed housings 313. Two limiting blocks 315 are fixedly connected to the bottom of each of the two telescopic rods 314.

Each trapezoidal slider 310 has a first drain opening 311 on its surface. A drain pipe 318 is fixedly connected to the bottom of each trapezoidal slider 316. The two drain pipes 318... The bottom of each is fixedly connected with a pressing column 319. Five metal blades with triangular cross-sections are equidistantly arranged on the surface of the pressing column 319, which serve to remove weeds from the soil surface and inside. Both pressing columns 319 have a three-hole 320 inside. The shape of the three-hole 320 is adapted to the shape of the two-hole 317, the one-hole 311 and the spreading hole 18, so that the three-hole 320 can fit tightly with the two-hole 317, the one-hole 311 and the spreading hole 18.

[0041] The spreading assembly 4 includes a fertilizer spreading box 41, which is inserted into the inside of the box body 11. The bottom of the inner wall of the fertilizer spreading box 41 has a fertilizer spreading hole 42, and the bottom of the outer wall of the fertilizer spreading box 41 has a transmission groove 43. A spring 44 is fixedly connected to one end of the transmission groove 43 near the spreading box 17, and an L-shaped plate 45 is fixedly connected to the other end of the spring 44 away from the spreading box 17. The surface of the L-shaped plate 45 has holes, the shape of which matches the shape of the fertilizer spreading hole 42, so as to achieve a tight fit between the L-shaped plate 45 and the fertilizer spreading hole 42. The L-shaped plate 45 is slidably connected to the transmission groove 43, and rotary tillage blades 46 are equidistantly arranged in a ring around the middle of the press wheel 14.

[0042] Working principle: In the initial state, the connecting wheel 12 is not connected to the external machinery via the traction rod on the rear support frame of the external machinery. The external machinery does not drive the roller 16 to move or rotate. The belt 21 does not drive the transmission at both ends of the transmission shaft 15. The belt 21 does not drive the rotating shaft 22 to rotate. The rotating shaft 22, through the helical gear 24, prevents the helical gear 25 from rotating. The helical gear 25 does not drive the spur gear 26 to rotate. The spur gear 26 drives the spur gear 22 to rotate. The spur gear 22, through the fixed plate 33, causes the rotating shaft 22 to rotate. 5. At the end of the slot plate 34 away from the center, spring 1 312 is not compressed, spring 2 44 is not compressed, trapezoidal slider 1 310 is located inside the sliding groove 39 on the side near the positioning rod 38, the outlet 1 311 is not connected to the spreading hole 18, the limiting block 315 does not move as a piston on the telescopic rod 314, the bottom of the feeding box 17 is in a sealed state, the L-shaped plate 45 is located inside the transmission groove 43 on the side near the spur gear 1 26, the L-shaped plate 45 is not connected to the fertilizer spreading hole 42, and the bottom of the fertilizer spreading box 41 is in a sealed state.

[0043] At work, such as Figure 1 - Figure 2As shown, the operator puts the seed material into the seeding box 17 and the fertilizer into the fertilizer spreading box 41. After that, the operator places the connecting wheel 12 on the support frame at the rear of the external machinery and aligns it with the traction rod on the external machinery. Then, the operator connects the connecting wheel 12 of the rotary tiller seeder to the traction rod and tightens the bolts. The external traction machine used here is a tractor. At this time, the operator starts the tractor on the field to be cultivated. The tractor drives the box 11 to move through the connecting wheel 12. Since the roller 16 is rotatably connected to the box 11 through the transmission housing 13, the roller 16 moves and rotates on the surface of the field to be cultivated while the box 11 moves. Since the roller 16 is fixedly connected to both ends of the drive shaft 15 and the belt 21 drives the transmission... Connected to both ends of the drive shaft 15, the roller 16 rotates while the roller 16 rotates, causing the rotating shaft 22 to rotate inside the fixed frame 23 via the belt 21. Since the helical gear 24 meshes with the helical gear 25, the helical gear 25 rotates through the helical gear 24 during the rotation of the rotating shaft 22. Since the helical gear 25 is fixedly connected to the spur gear 26 and the helical gear 25 and the spur gear 26 are concentric, the spur gear 26 rotates through the fixed rod 27 at the bottom of the inner wall of the box 11 while the bottom of the spur gear 26 meshes with the spur gear 32, the spur gear 32 rotates through the fixed rod 31 at the bottom of the outer wall of the feeding box 17 while the spur gear 26 rotates.

[0044] Rotary tillage seeders compact the soil in the field and sow seeds.

[0045] like Figure 2 - Figure 5 As shown, because the second rotating shaft 35 is fixedly connected to the bottom of the fixed plate 33 and slidably connected inside the slot plate 34, the rotation of the fixed plate 33 drives the second rotating shaft 35 to rotate around the center of the fixed plate 33. Consequently, as the second rotating shaft 35 rotates, it also drives the slot plate 34, causing the slot plate 34 to tend to rotate around the center of the fixed plate 33 as well. Figure 5As shown, both sides of the slot plate 34 are fixedly connected to the positioning rod 38 via fixing blocks 37, and the end of the positioning rod 38 away from the slot plate 34 is fixedly connected to the trapezoidal slider 310. The trapezoidal slider 310 slides inside the sliding groove 39. Under the limiting action of the trapezoidal slider 310, the slot plate 34 can only slide towards the left and right sides of the positioning rod 38. During the rotation of the fixing piece 33, it will abut against the inner wall of the slot plate 34, causing the slot plate 34 to shift towards the side of the positioning rod 38. Because the slot plate 34 shifts, the positioning rod 38 will shift synchronously, causing the trapezoidal slider 310 fixedly connected to the positioning rod 38 to shift synchronously towards the side away from the slot plate 34. During the displacement of the trapezoidal slider 310, it will abut against the trapezoidal slider 316, and the spring 312 will be in an extended state, thereby pushing the trapezoidal slider. Because the telescopic rod 314 is fixedly connected to the limiting block 315, the trapezoidal slider 316 moves towards the bottom of the box 11 and extends the telescopic rod 314. At this time, the pressing column 319, which is fixedly connected to the trapezoidal slider 316, will press the soil of the field due to the force of the trapezoidal slider 316 moving towards the bottom of the box 11. The metal blades equidistantly arranged on the surface of the pressing column 319 will chop the weeds. When sowing, the pressing column 319 will break the soil and cut off the grass roots, avoiding the problem that the grass roots in the soil will get tangled on the blade shaft during sowing, causing the blade shaft to slow down or stop rotating. This structure not only improves the overall tillage efficiency of the rotary tiller, but also improves the soil's aeration, water permeability and nutrient supply capacity by cutting off the grass roots in the soil, making the soil more conducive to crop growth and nutrient absorption, thereby reducing subsequent maintenance work.

[0046] Furthermore, the movement of trapezoidal slider 1 (310) pushes trapezoidal slider 2 (316), causing the spreading hole 18, the first drain 311, and the second drain 317 to be connected. The bottom of the seeding box 17 is no longer sealed, and crop seeds fall from the seeding box 17 through the spreading hole 18, the first drain 311, the second drain 317, the drain pipe 318, and the third drain 320 into the compacted soil. The slot plate 34 pushes the positioning rod 38, causing the seeds to leak from inside the compaction column 319 and fall onto the cultivated land. This prevents crops from growing in concentrated areas, solving the problem of poor growth due to nutrient deficiency caused by concentrated crop growth. This structure, through staggered planting, allows for more even plant growth, preventing crops from blocking light and causing poor growth, and increases the space for harvesting crops. The gaps facilitate manual operation or the entry of machinery during harvesting. Furthermore, staggered planting effectively reduces the risk of pest and disease transmission, helping crops maintain healthy growth. As the fixed plate 33 continues to rotate, the slot plate 34 shifts towards the other side of the positioning rod 38, causing the positioning rod 38 on one side to move in the opposite direction. During this process, trapezoidal slider 1 310 no longer contacts trapezoidal slider 2 316 and moves in the opposite direction. During this process, trapezoidal slider 1 310 compresses spring 1 312. Because the telescopic rod 314 is no longer under force, it begins to retract and reset, thereby causing trapezoidal slider 2 316 on one side to reset. This also de-connects the feeding hole 18, the first outlet 311, and the second outlet 317, sealing the bottom of the feeding box 17 once again.

[0047] Rotary tillers till and fertilize the soil in fields.

[0048] like Figure 2-3As shown, simultaneously, the rotary tiller blades 46, which are fixedly connected to the press wheel 14, rotate synchronously and till the field. The rotating rotary tiller blades 46 also come into contact with the L-shaped plate 45, pushing it closer to the helical gear 24. At this point, the movement of the L-shaped plate 45 compresses the transmission groove 43. Simultaneously, the groove on the surface of the L-shaped plate 45 connects with the fertilizer application hole 42 at the bottom of the fertilizer application box 41. The bottom of the fertilizer application box 41 is no longer sealed, allowing fertilizer to fall from the application hole 42 into the tilled furrow. The rotary tiller blades 46 push the L-shaped plate 45, causing the fertilizer to leak out from inside the L-shaped plate 45 and fall onto the tilled land, preventing the newly tilled soil from lacking sufficient soil for crop growth. The lack of nutrients leads to crop depletion. This structure, by applying fertilizer during the sowing process, not only achieves the rational use of resources but also improves the crop's growth conditions, thereby increasing its yield and further realizing the efficient use of farmland. At the same time, it improves the soil quality of farmland, making the soil richer in the nutrients needed for crop growth and sustainable use. Subsequently, due to the rotation of the press wheel 14, the rotary tiller 46 no longer contacts the L-shaped plate 45, so that the L-shaped plate 45 is pushed into the transmission groove 43 away from the helical gear 24 under the elastic action of the second spring 44. This causes the groove on the surface of the L-shaped plate 45 to connect with the fertilizer hole 42 at the bottom of the fertilizer box 41, so that the bottom of the fertilizer box 41 is sealed again.
