Abstract
Description
Technical Field
[0001] This application relates to the field of agricultural machinery, and in particular to a tillage device for agricultural machinery that facilitates material feeding. Background Technology
[0002] In existing agricultural tillage machinery, the sowing device usually includes a seed box, a seed metering device, and a sprocket box. The seed box is used to store seeds, and its bottom is connected to the seed metering device through a grain outlet. The seeds are supplied to the seed metering device by their own weight or a simple flow guiding structure. The seed metering device then discharges the seeds in a quantitative manner to achieve sowing. The sprocket box, as an existing technology, is usually connected to the drive of the seeder wheel, which can transmit the kinetic energy of the wheel during operation upwards to provide power for the quantitative sowing action of the seed metering device.
[0003] However, in actual operation, seeds tend to accumulate and compact at the connection between the seed metering device shell and the grain outlet, forming a "bridging" phenomenon. In particular, seeds with uneven particle size or containing a certain amount of moisture will form a stable arch-shaped structure due to mutual adsorption and compression, leading to interruption of seed supply. In view of this, this paper proposes a tillage device for agricultural machinery that facilitates feeding. Utility Model Content
[0004] In order to improve the problem that seeds tend to accumulate and compact at the connection between the seed metering device and the grain outlet, forming a "bridging" phenomenon that leads to interruption of seed supply, this application provides a tillage device for agricultural machinery that facilitates feeding.
[0005] The agricultural machinery tillage device for easy material feeding provided in this application adopts the following technical solution:
[0006] A tillage device for agricultural machinery that facilitates material feeding includes a seed box, with several seed metering devices fixedly connected to both sides of the lower part of the seed box, and a grain chamber provided inside the seed box, with a guide protrusion protruding upward from the middle area on the lower bottom surface of the grain chamber;
[0007] A reciprocating drive actuator and several baffle rods are provided above the center of the grain chamber. Several grain outlets for connecting to the seed metering device housing are provided below the two sides of the seed box. The ends of the baffle rods pass through the grain outlets and are located inside the seed metering device housing. The heads of the baffle rods are connected to the reciprocating drive actuator.
[0008] By adopting the above technical solution, the grain chamber of the seed box is used to store seeds. The guide protrusion on the bottom surface of the grain chamber can guide the seeds to flow to both sides. The reciprocating drive actuator above the middle of the grain chamber drives several turbulence rods to move. The ends of the turbulence rods pass through the grain outlets on both sides of the seed box and enter the seed metering device housing. Through reciprocating motion, the compaction and bridging of the seeds in the seed metering device housing is broken. Combined with the guiding effect of the guide protrusion, the seeds are smoothly fed into the seed metering device, effectively avoiding the problem of seed supply interruption.
[0009] Preferably, the reciprocating drive actuator includes a main rod, on which a plurality of cams are fixedly mounted. Each cam is equipped with a first bearing. A movable rod is mounted below the outer ring of the first bearing. The axis of the first bearing is parallel to and not collinear with the axis of the main rod. The movable rod is arranged parallel to the bottom of the main rod, and the head end of the deflector is inclinedly mounted on the movable rod.
[0010] By adopting the above technical solution, in the reciprocating drive actuator, when the main rod rotates, it drives the cams at both ends to rotate synchronously. Since the axis of the first bearing is parallel to and not collinear with the axis of the main rod, the first bearing on the periphery of the cam drives the movable rod to reciprocate below the main rod, thereby driving the baffle rod that is inclinedly installed on the movable rod to move.
[0011] Preferably, a connecting block is fixedly connected below the outer ring of the first bearing, and a third bearing is fixedly connected to one side of the connecting block. The connecting block is rotatably connected to one end of the movable rod through the third bearing.
[0012] By adopting the above technical solution, the connecting block below the outer ring of the first bearing is rotatably connected to one end of the movable rod through the third bearing on one side, which helps the movable rod to move stably.
[0013] Preferably, a second bearing is coaxially connected to the movable rod, and two vertically upward guide rods are fixedly installed in the grain chamber, with the two guide rods clamped and connected to both sides of the second bearing.
[0014] By adopting the above technical solution, the second bearing on the movable rod is clamped by two vertical guide rods in the grain chamber, which limits the direction of movement of the movable rod.
[0015] Preferably, a sprocket box is fixedly installed on one side of the seed box, and one end of the main rod passes through the seed box and is connected to a sprocket in the sprocket box.
[0016] By adopting the above technical solution, the sprocket box on one side of the seed box is connected to one end of the main rod through an internal sprocket, providing rotational power to the main rod.
[0017] Preferably, several internally threaded cylinders are fixedly connected to the lower sides of the movable rod, and a screw is fixedly connected to the head end of the turbulence rod, the screw being threaded into the internally threaded cylinder.
[0018] By adopting the above technical solution, the internal threaded cylinders on both sides of the movable rod are threadedly connected to the screw at the head of the spoiler rod, thereby realizing the detachable connection between the spoiler rod and the movable rod.
[0019] Preferably, the section of the spoiler rod from the middle to the end is designed as a triangular corrugated curved structure, and the shape of the triangular corrugated curved structure extends along the three-dimensional direction in space.
[0020] By adopting the above technical solution, the triangular corrugated bending structure of the turbulence bar from the middle to the end enhances the destructive effect on seed bridging inside the seed metering device housing.
[0021] Preferably, the cross-section of the guide protrusion is an isosceles triangle.
[0022] By adopting the above technical solution, the isosceles triangular cross-sectional structure of the guide protrusion allows the seeds at the bottom of the grain chamber to flow evenly to the seed metering devices on both sides.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] This invention, through the guide protrusion on the bottom surface of the grain chamber, can actively guide the seeds to flow to the seed metering devices on both sides, solving the problems of seed accumulation in the middle of the seed box and uneven seed supply on both sides, thus improving the uniformity of seed supply. At the same time, the reciprocating drive actuator drives the turbulence rod to reciprocate within the seed metering device housing, which can directly disrupt the bridging structure formed by the seeds within the seed metering device, avoiding seed supply interruptions caused by compaction and blockage. The synergistic effect of the guide protrusion and the reciprocating drive actuator effectively ensures the smooth feeding of seeds into the seed metering device, improving the stability of the sowing operation.

[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0035] This application discloses a tillage device for agricultural machinery that facilitates material feeding.
[0036] Reference Figure 1 , Figure 2 A tillage device for agricultural machinery that facilitates feeding includes a seed box 1, at least twelve seed metering devices 2, and a sprocket box 6. The seed box 1, seed metering devices 2, and sprocket box 6 are existing technologies. The sprocket box 6 is fixedly connected to one side of the seed box 1. The twelve seed metering devices 2 are respectively fixedly connected to the lower two sides of the seed box 1. Twelve grain outlets 13 are provided on the lower sides of the seed box 1. The grain outlets 13 are used to connect to the shells of the seed metering devices 2. The seed box 1 is provided with a grain chamber 11 for holding grain seeds. The lower bottom surface of the grain chamber 11 has a guide protrusion 12 with an isosceles triangular cross-section protruding upward from the middle area.
[0037] Seed box 1 is used for overall support and installation of various components. The sprocket box 6 adopts the transmission structure of the seeder wheel in the existing technology. When fixed to one side of seed box 1, it can transmit the kinetic energy of the wheel to the internal sprocket, providing a power foundation for the subsequent operation. The twelve seed metering devices 2 are connected to the grain chamber 11 through the grain outlets 13 on both sides of the seed box 1, realizing the receiving and discharging of seeds. The grain chamber 11 serves as a seed storage space. The cross-section of the guide protrusion 12 on its bottom surface is designed as an isosceles triangle structure. The symmetrical inclined surface can be used to evenly guide the seeds at the bottom of the grain chamber 11 to the grain outlets 13 on both sides, avoiding the accumulation of seeds in the middle of the grain chamber 11 and providing a balanced seed supply for the seed metering devices 2.
[0038] Reference Figure 3 The grain chamber 11 is equipped with a reciprocating drive actuator 3, which is located above the center of the grain chamber 11, higher than the height of a typical grain seed container. The reciprocating drive actuator 3 includes a main rod 31 rotatably connected to the seed box 1, two cams 32 fixing both ends of the main rod 31, two first bearings 33 respectively connected to the two cams 32, and a movable rod 34 installed parallel to the bottom of the main rod 31. The axes of the first bearings 33 and the axis of the main rod 31 are parallel to each other, but not collinear. The inner ring of the first bearing 33 is fixedly connected to the cam 32. One end of the main rod 31 passes through the seed box 1 and is fixedly connected to a sprocket in the sprocket box 6. A connecting block 37 is provided below the first bearing 33. The connecting block 37 is fixedly connected to the outer ring of the first bearing 33. A third bearing 38 is provided on one side of the connecting block 37. The inner ring of the third bearing 38 is fixedly connected to the connecting block 37. The two ends of the movable rod 34 are respectively provided with round holes for connecting the third bearing 38. The outer ring of the third bearing 38 is hidden and fixedly installed in the round hole at one end of the movable rod 34.
[0039] The reciprocating drive actuator 3 is located above the middle of the grain chamber 11 and is higher than the general seed storage height. This reduces direct contact with the seeds and lowers the risk of jamming caused by seed entanglement or compression. The main rod 31 is rotatably connected to the seed box 1. One end of the main rod 31 is fixed to the sprocket in the sprocket box 6. It can receive power through sprocket transmission and drive the cams 32 at both ends to rotate synchronously. Since the axis of the first bearing 33 is parallel to and not collinear with the axis of the main rod 31, when the cam 32 rotates, it will drive the connecting block 37 to reciprocate through the first bearing 33. The inner ring of the third bearing 38 on one side of the connecting block 37 is fixed to the connecting block 37. The outer ring of the third bearing 38 is hidden in the round hole at the end of the movable rod 34. This reduces the frictional resistance between the connecting block 37 and the movable rod 34 through the rotation of the bearing and prevents seeds from entering the bearing gap and causing wear or jamming. Finally, it drives the movable rod 34 to reciprocate stably below the main rod 31.
[0040] Reference Figure 3 , Figure 5 The movable rod 34 is connected to a second bearing 36 on the outer wall near both ends. The second bearing 36 and the movable rod 34 are coaxially arranged, and the movable rod 34 and the second bearing 36 have the same diameter. Two guide rods 4 are fixedly installed inside the grain chamber 11. The guide rods 4 are vertically upward and are located on both sides of the second bearing 36, and the guide rods 4 are in contact with the outer ring of the second bearing 36. Twelve circular cross-section baffle rods 5 are installed on both sides below the movable rod 34. The baffle rods 5 are made of corrosion-resistant, wear-resistant, and high mechanical strength materials. Made of stainless steel, the baffle rod 5 is inclined and its end passes through the grain outlet 13 and is located inside the seed metering device 2 housing. Twelve internal threaded cylinders 35 are respectively provided on the lower sides of the movable rod 34. The movable rod 34 and the internal threaded cylinders 35 are fixedly connected. The head end of the baffle rod 5 is provided with a screw 51. The baffle rod 5 and the screw 51 are fixedly connected. The screw 51 is threadedly disassembled and connected to the internal threaded cylinder 35. The rod section of the baffle rod 5 from the middle to the end is designed as a triangular corrugated curved structure that extends in three-dimensional space.
[0041] The second bearing 36 on the movable rod 34 is coaxial with the movable rod 34 and has the same diameter. The two vertical guide rods 4 in the grain chamber 11 are clamped on both sides of the second bearing 36 and contact its outer ring, which can limit the movable rod 34 to reciprocate only in the vertical direction, avoiding the instability of the turbulence rod 5 caused by its deviation. The turbulence rod 5 has a circular cross-section, which can reduce the shear force of the turbulence rod 5 on the grain. The movable rod 34 is threaded to the screw 51 at the head end of the turbulence rod 5 through the internally threaded cylinders 35 on both sides, which are inclined downwards, to realize the turbulence rod 5. The detachable and easy-to-maintain or replaceable baffle rod 5 is adapted to different seeds. The baffle rod 5 is inclined and its end extends through the grain outlet 13 into the seed metering device 2 housing. The triangular corrugated curved structure of the baffle rod 5 extending from the middle to the end in a three-dimensional spatial direction can increase the contact range and disturbance intensity with the seeds during reciprocating motion, and more efficiently break the seed bridging in the seed metering device 2 housing. The contact part between the second bearing 36 and the guide rod 4 has a compact structure, which can reduce the number of seeds entering the bearing and play a protective role.
[0042] The implementation principle of the agricultural machinery tillage device for easy feeding in this application embodiment is as follows: This agricultural machinery tillage device for easy feeding is suitable for field tillage operations of grain seeds such as corn and soybeans. Especially when the seeds contain a small amount of impurities, are slightly damp, or the working environment is bumpy, the uniform distribution of seeds by the guide protrusion 12 and the precise arch breaking of the turbulence rod 5 driven by the reciprocating drive actuator 3 can continuously and stably deliver seeds to the seed metering device 2, effectively reducing the number of times the machine stops due to blockage, improving the continuity and uniformity of sowing, adapting to the tillage scenario of small and medium-sized tractors, and reducing manual maintenance costs.
[0043] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
