Description

Technical Field

[0001] The present invention relates to the technical field of intelligent agricultural power machinery, in particular to an intelligent agricultural power machinery for planting crops, furrowing, sowing and fertilizing. Background Art

[0002] With the continuous development and progress of modern agricultural technology, the mechanized planting of plant crop seeds currently generally uses agricultural power machinery such as sowing machinery to assist manual work.

[0003] In the prior art, when sowing plant crop seeds, the traditional mechanical operation process is mainly to first use a plowing machine to open a furrow, then cooperate with a sowing machine to complete the sowing, and finally fill the furrow after watering and fertilizing.

[0004] After searching, a patent document with patent application number CN201822092084.2 discloses a seeder for agricultural sowing, whose main structure includes a seeder body, a feeding device and a soil crushing device. The seeder body includes a sowing bucket, a seeding tube, a connecting pipe, a sowing tube and a sowing plow. The soil crushing device is installed on one side of the sowing tube. The soil crushing device includes a soil crushing rake fixing frame, a soil crushing rake and a fixed clamping protrusion. The soil crushing rake fixing frame is located on the side surface of the sowing tube, a fixed clamping groove is arranged inside the soil crushing rake fixing frame, and soil crushing rake teeth are arranged inside the soil crushing rake.

[0005] It can be seen from the structure of the above-mentioned existing seeder that it mainly utilizes multiple sowing plows arranged side by side in conjunction with a sowing tube to complete multi-row sowing. Although this structure increases the sowing efficiency to a certain extent, in the actual operation process, when sowing between the furrows and ridges of two adjacent fields, it is necessary to select a suitable spacing distance according to the terrain and the type of plant sowing. The above-mentioned seeder is obviously unable to adjust the ridge spacing; in addition, considering reasonable lighting, mixed planting is generally required when planting crops with higher plants in farmland. Therefore, different seeds need to be flexibly planted and sown between the furrows and ridges of adjacent fields to form a mixed planting pattern. There are certain difficulties in planting using the seeder with existing technology, and the planting effect cannot be guaranteed.

[0006] Based on this, the present invention optimizes and improves the problems existing in the prior art in the actual process of crop planting in farmland, and hereby proposes an intelligent agricultural power machinery that is linked to crop furrowing, sowing and fertilization, so as to better improve the sowing efficiency of crop plants and better solve the problems existing in the prior art.

Figure 1-Figure 9 as shown in .

[0038] In any of the above schemes, it is preferred that a pushing handle frame 7 is fixedly installed at the rear end of the frame 1, a horizontally arranged grasping handle 8 is fixedly installed on the top of the pushing handle frame 7, and remote controllers 9 are respectively installed at both ends of the grasping handle 8, and the remote controller 9 is used to control the operation of the circuits and signals of the linkage shifting mechanism, the spray unit 3, each of the fertilizer units 5 and each of the groove units 6.

[0039] When operating the entire machine, the gripping handle 8 on the handle frame 7 can be pushed by manpower to facilitate the exertion of force, and the remote controller 9 can be controlled by both hands during the pushing process to achieve the purpose of quickly controlling the corresponding unit for timely response.

[0040] In any of the above schemes, it is preferred that the front wheel group includes two front end wheel frames 10 relatively spaced apart and arranged on both sides of the bottom of the frame 1, a front wheel axle 11 is movably installed in each of the front end wheel frames 10, and a front wheel 12 is fixedly installed at the end of the front wheel axle 11.

[0041] In any of the above schemes, it is preferred that the rear wheel group includes two rear end wheel frames 13 relatively spaced apart on both sides of the bottom of the frame 1, a rear wheel axle 14 is arranged between the two rear end wheel frames 13, and both ends of the rear wheel axle 14 are movably passed through the rear end wheel frames 13 at corresponding positions and rear wheels 15 are fixedly installed at their ends.

[0042] In the present invention, the support and operation of the two front wheels 12 at the front side and the two rear wheels 15 at the rear side can effectively ensure the stability and smoothness of the entire machine when it is moving.

[0043] In any of the above schemes, it is preferred that the linkage shifting mechanism includes two fixed frames 16 respectively fixedly mounted on the front end top and rear end top of the frame 1, a bidirectional lead screw 17 is installed inside the fixed frame 16, the front and rear ends of the bidirectional lead screw 17 are movably extended to the outside of the fixed frame 16 through the stepped shafts at the ends thereof, the rotation directions of the lead screws on both sides of the middle of the bidirectional lead screw 17 are opposite, and a movable slide 18 is screwed together on the outer side walls on both sides of the bidirectional lead screw 17, the side walls of each movable slide 18 are movably abutted against the inner side walls of the fixed frame 16, and the top of each movable slide 18 is movably hinged with the corresponding end of the scissor-type positioning control mechanism, and when the two bidirectional lead screws 17 drive each movable slide 18 to approach or move away from each other, the scissor-type positioning control mechanism and the adjustment of the positions of the respective sowing units 4, the respective fertilizing units 5 and the respective groove units 6 thereon can be driven; A screw motor 19 is fixedly installed at the end of the fixed frame 16 on the front side, and the motor shaft of the screw motor 19 is fixedly connected to the end of the bidirectional screw 17 at its corresponding position. Pulleys 20 are fixedly installed at the ends of the two bidirectional screws 17 at the opposite end of the screw motor 19, and the two pulleys 20 are connected by a toothed belt 21.

[0044] It should be noted that: when it is necessary to control the operation of the interlocking shifting mechanism, the screw motor 19 is first controlled to start. When the screw motor 19 is running, it can drive the two bidirectional screws 17 to operate synchronously. During the operation of the two bidirectional screws 17, the various movable slides 18 installed thereon can be adjusted and shifted as needed, so as to achieve the purpose of getting closer to or away from each other.

[0045] In addition, considering that the machine is performing crop seed sowing operations, the relative or opposite operation of each movable slide 18 can be controlled by relying on the on-demand rotation of the bidirectional lead screw 17 at both ends, so that the two ends of the scissor-type control mechanism can be quickly controlled to be opened or closed with its center as the hinge point, thereby effectively realizing the regulation of the spacing distance when the entire machine is opening grooves and the spacing distance when synchronous sowing is carried out between adjacent ridges or the control of the folding amplitude when alternating S-shaped sowing, effectively achieving the purpose of reasonably controlling the sowing spacing distance or alternating planting of S-shaped fold lines during mixed planting, improving the lighting effect between adjacent seed plants after planting, and reducing the impact of light blocking.

[0046] In any of the above schemes, it is preferred that the scissor-type control mechanism includes two rigid linkage rods 22, the centers of the two rigid linkage rods 22 are movably hinged, and the two ends of each rigid linkage rod 22 are respectively movably hinged on the top of the two movable slides 18 arranged at intervals along the diagonal line, and a central constraint sleeve 23 is fixedly installed on the top of the central hole of the upper rigid linkage rod 22 and the bottom of the central hole of the lower rigid linkage rod 22, and the spray unit 3 is fixedly installed in the through cavity of the central constraint sleeve 23, and the spray unit 3 is used to simultaneously water the grooves on both sides thereof, and the sowing unit 4 and the fertilizing unit 5 are respectively installed on each of the rigid linkage rods 22 along its length direction, the sowing unit 4 is located at the front side of the fertilizing unit 5, and the groove unit 6 is arranged between the fertilizing unit 5 and the sowing unit 4, and the two ends of the top of the groove unit 6 are respectively movably hinged on the sowing unit 4 and the fertilizing unit 5 at the corresponding positions.

[0047] It should be noted that the scissor-type positioning mechanism as a whole is a passive linkage structure and does not have any power parts of its own. When it is necessary to control the two rigid linkage rods 22 on the scissor-type positioning mechanism to make a scissor-like opening or closing movement, it is sufficient to control the operation of the two bidirectional lead screws 17 on the linkage shifting mechanism. When the two bidirectional lead screws 17 are in operation, they can drive the movable slides 18 on each of them to move closer to or away from each other, thereby achieving the purpose of facilitating the required adjustment and control. In addition, after each movable slide 18 is adjusted and controlled into place, it can be locked in time by relying on the bidirectional lead screw 17, thereby effectively ensuring the stability after it is in place.

[0048] The outer wall of the central restraint sleeve 23 and the hinge hole of the rigid linkage rod 22 are engaged with each other through an annular snap fit to ensure that the central restraint sleeve 23 can rotate along a fixed axis and bear load vertically upward in water. The middle outer diameter of the central restraint sleeve 23 is larger than its upper and lower outer diameters.

[0049] In addition, since both ends of each rigid linkage rod 22 are movably sleeved on the outer side wall of the corresponding column fixedly connected to the bottom of the movable slide 18, alloy pressure rings are coaxially fixedly connected to the outer side wall of the column below each rigid linkage rod 22.

[0050] In any of the above schemes, it is preferred that the sowing unit 4 includes a vertical sowing tube 24 fixedly mounted on the rigid linkage rod 22, a sowing precision screw feeder 25 is fixedly mounted on the top of the vertical sowing tube 24, a seed silo 26 is fixedly mounted at the top feed port of the sowing precision screw feeder 25, and the sowing precision screw feeder 25 is controlled by a remote control 9 or a corresponding sowing control switch 42.

[0051] When working, the sowing unit 4 relies on controlling the working time of the sowing precision screw feeder 25 (the sowing precision screw feeder 25 can adopt the precision feeder structure in the prior art) to effectively control the approximate amount of current seed discharge, and effectively complete each seed nest (i.e., each nest formed by a pile of sown seed grains) according to different seed types to sow an appropriate number of seeds as required.

[0052] In any of the above schemes, it is preferred that the fertilization unit 5 includes a vertical fertilization pipe 27 fixedly mounted on the rigid linkage rod 22, a precision fertilizer screw feeder 28 is fixedly mounted on the top of the vertical fertilization pipe 27, a fertilizer silo 29 is fixedly mounted at the top feed port of the precision fertilizer screw feeder 28, and the precision fertilizer screw feeder 28 is controlled by a remote control 9.

[0053] Similarly, after sowing is completed, the fertilization unit 5 arranged on the rear side relies on the remote control 9 to control the working time of the fertilizer precision screw feeder 28 (the fertilizer precision screw feeder 28 can use the precision feeder in the prior art) to effectively control the amount of fertilizer required to be fed to each nest, thereby ensuring accurate fertilization amount.

[0054] In any of the above schemes, it is preferred that the groove unit 6 includes a horizontally arranged two-way telescopic rod 30, and the two ends of the two-way telescopic rod 30 are respectively movably hinged on the ear seats of the outer wall of the vertical sowing tube 24 and the corresponding ear seats of the outer wall of the vertical fertilization tube 27 at corresponding positions. Lifting electric cylinders 31 are symmetrically fixed on both sides of the bottom of the middle section of the two-way telescopic rod 30, and the bottoms of the piston rods of the two lifting electric cylinders 31 are fixedly installed on the top of the horizontal connecting seat 32 at the corresponding position. An inclined rigid frame 33 is arranged below the horizontal connecting seat 32, and the rear end of the inclined rigid frame 33 is movably hinged to the horizontal connecting seat 32. At the bottom of the inclined rigid frame 33, a furrowing plowshare 36 is installed in the mounting wheel frame 34 at the front end of the inclined rigid frame 33, both ends of the central axis of the furrowing plowshare 36 are movably extended to the outside of the mounting wheel frame 34 and one end of the central axis is connected to a driving motor 35 fixedly mounted on the outer wall of the mounting wheel frame 34, and the furrowing plowshare 36 realizes trenching on the land surface by its own rotation, and a swing-controlled electric cylinder 37 is arranged in the middle of the inclined rigid frame 33, the top of the swing-controlled electric cylinder 37 is movably hinged to the bottom of the horizontal connecting seat 32, and the bottom of the swing-controlled electric cylinder 37 is movably hinged to the top of the middle section of the inclined rigid frame 33.

[0055] It should be noted that: firstly, the entire groove unit 6 is located on the same straight line as the corresponding sowing unit 4 and fertilizing unit 5, ensuring that the subsequent sowing and fertilizing processes can run normally and quickly after the groove is excavated.

[0056] In addition, the trench unit 6 is mainly located in the front-end process during operation. When the trench unit 6 is started, the lifting and lowering of the horizontal connecting seat 32 below it can be driven by controlling the lifting and lowering of the lifting electric cylinder 31, thereby achieving preliminary adjustment of the height position; when it is necessary to accurately adjust the excavation angle, the extension and retraction of the swing control electric cylinder 37 can drive the front end of the inclined rigid frame 33 to achieve different inclination angles for excavation, so that it can be better suitable for trenching in fields with certain inclination angles in mountains and hills.

[0057] In addition, when trenching, the operating speed of the trenching rake 36 can be effectively guaranteed by controlling the operating speed of the driving motor 35, thereby ensuring different trenching effects.

[0058] In any of the above solutions, it is preferred that the front end of each of the inclined rigid frames 33 is tilted downward and the two inclined rigid frames 33 are independent of each other during operation.

[0059] When trenching in mountainous areas, considering the presence of rocks between adjacent ridges, the two inclined rigid frames 33 are controlled to operate independently, so that the trenching plow 36 at the front end of the inclined rigid frame 33 can be temporarily lifted when rocks are dug, thereby reducing excessive collision and wear of the cutter of the trenching plow 36.

[0060] In any of the above schemes, it is preferred that the spray unit 3 includes a metal spray riser 38 vertically fixedly installed in two central restraint sleeves 23 coaxially arranged from top to bottom, a water storage cylinder 39 is fixedly installed on the top of the metal spray riser 38, and electric spray nozzles 40 are symmetrically installed on both sides of the bottom of the metal spray riser 38, and each electric spray nozzle 40 is used to spray liquid into the groove on its corresponding side.

[0061] It should be noted that: when the spray unit 3 is in operation, by controlling the start of the electric spray nozzle 40, it can simultaneously spray water into the inside of two adjacent soil ridge grooves, thereby achieving the purpose of quickly spraying water after sowing. Controlling the opening of the electric spray nozzle 40 can effectively control the amount of water sprayed into the groove.

[0062] Embodiment 2: Compared with Embodiment 1, this embodiment is different in that it also includes the following technical features: In any of the above schemes, preferably, angle steel frames 41 are fixedly mounted on the rear wheel frame 13 above the outer side walls at both ends of the rear wheel axle 14, and sowing control switches 42 are fixedly mounted on the bottom of the horizontal sections of each angle steel frame 41, and linkage cams 43 are fixedly mounted on the outer side walls of the rear wheel axle 14 directly below each sowing control switch 42, and when the linkage cam 43 rotates on a fixed axis, it can drive the opening and closing of the sowing control switch 42 by pressing, and the two linkage cams 43 are arranged 180° apart on the circumference, and when the rear wheel axle 14 runs continuously, the two linkage cams 43 can alternately trigger the sowing control switches 42 at corresponding positions, and each sowing control switch 42 is a spring-type pressing switch, and each sowing control switch 42 is used to control the opening and closing of the sowing precision spiral feeder 25 of the sowing unit 4 at its corresponding position. Each sowing control switch 42 can be temporarily closed as needed.

[0063] It should be noted that: considering that when carrying out mixed planting operations, it is necessary to select a reasonable planting spacing according to the plant type, a linkage cam 43 is set and the circumferential spacing arrangement angle between the two linkage cams 43 is controlled to control the frequency of alternating sowing of seeds of the same type or different types of plants and the spacing distance between two seed piles on the same ridge, thereby effectively achieving the purpose of reasonably controlling the planting interval; since the sowing control switch 42 adopts a spring-type press switch, it can automatically return to its original position after the pressure disappears, thereby ensuring the continuous alternating action of the sowing control switch 42 when the rear wheel axle 14 continues to operate.

[0064] In addition, taking into account the unified control of the start-up time of the sowing control switch 42, it is set here that the continuous effective time after each triggering of the sowing control switch 42 is maintained at 1-2S, so that the seed output can be effectively and reasonably controlled when controlling the operation of the precision feeder; wherein, according to the requirements of different seed planting types, the continuous effective time after each triggering of the sowing control switch 42 can be pre-adjusted.

[0065] Specific working principle: The plant crop furrowing, sowing and fertilization linkage intelligent agricultural power machinery designed in the present invention can move along the soil ridge direction by relying on the linkage of the front wheel group and the rear wheel group under the action of human power.

[0066] According to the types of crops that need to be sown in the field and the planting specifications, the current linkage shifting mechanism is controlled to shift, thereby driving the scissor-type control mechanism to link the sowing unit 4, the fertilizing unit 5, and the groove unit 6 thereon to match the spacing distance requirements of the Xinglin soil ridge grooves, so that the matching correspondence can be effectively completed according to the actual sowing needs. During the working process, electric trenching, seed sowing, watering and fertilizing can be realized in succession, effectively ensuring the smooth operation of multiple planting actions and improving the sowing and planting efficiency.

[0067] When it is necessary to sow at intervals and control the sowing distance or to adopt Z-shaped or S-shaped zigzag sowing, first control the screw motor 19 to start. When the screw motor 19 is running, it can drive the two bidirectional screws 17 to operate synchronously. During the operation of the two bidirectional screws 17, the movable slides 18 installed thereon can be adjusted and shifted as needed, so as to achieve the purpose of getting closer or farther away from each other.

[0068] In addition, considering that the machine is performing crop seed sowing operations, the relative or opposite operation of each movable slide 18 can be controlled by relying on the on-demand rotation of the bidirectional lead screw 17 at both ends, so that the two ends of the scissor-type control mechanism can be quickly controlled to be opened or closed with its center as the hinge point, thereby effectively realizing the regulation of the spacing distance when the entire machine is opening grooves and the spacing distance when synchronous sowing is carried out between adjacent ridges or the control of the folding amplitude when alternating S-shaped sowing, effectively achieving the purpose of reasonably controlling the sowing spacing distance or alternating planting of S-shaped fold lines during mixed planting, improving the lighting effect between adjacent seed plants after planting, and reducing the impact of light blocking.

[0069] In addition, reasonable electric control of each mechanism and unit can effectively ensure relative speed in the entire control process.

[0070] Specifically, when the trench unit 6 is working, it is located in the front-end process. When the trench unit 6 is started, by controlling the lifting of the lifting electric cylinder 31, the lifting of the horizontal connecting seat 32 below it can be driven, thereby achieving preliminary adjustment of the height position; when it is necessary to accurately adjust the excavation angle, by controlling the extension and retraction of the swing control electric cylinder 37, the front end of the inclined rigid frame 33 can be driven to achieve different inclination angles for excavation, so that it can be better suitable for trenching in fields with certain inclination angles in mountains and hills.

[0071] In addition, when trenching, the operating speed of the trenching rake 36 can be effectively guaranteed by controlling the operating speed of the driving motor 35, thereby ensuring different trenching effects.

[0072] From the above, it can be seen that the plant crop furrowing, sowing and fertilization linkage intelligent agricultural power machinery in the present invention can realize the simultaneous furrowing of double ridges when dealing with field crop sowing, and can quickly realize the linkage operation of sowing, spraying water and fertilizing after trenching. The overall sowing and other planting operations are highly efficient, and the operation is simple and fast. When sowing and planting different plant seeds, the linkage shifting mechanism can be adjusted in advance according to needs. After the adjustment is completed, the spacing distance between the two adjacent ridges can be achieved when the entire machine is sowing, thereby better matching the current plant planting indicators.

[0073] In addition, when planting plants, Z-type staggered sowing can be effectively achieved by staggered control of the opening of the corresponding sowing units 4, effectively ensuring the staggered effect between the plants in the later stage of sowing and improving the lighting effect of the plants; when the sowing is completed, the water spraying unit designed in the present invention can simultaneously complete the rapid and synchronous spraying of water to the plants in the two ridges. When the types of seeds of the plants in the two ridges are different, if there are different requirements for the amount of watering, water spraying on demand can be achieved by independently controlling the nozzles of the two water spraying units.
