DETAILED DESCRIPTION

[0027] In order to fully describe the technical content, structural features, objectives and effects of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.

[0028] See also Figure 1 The present invention provides a water, fertilizer and seed integrated seeder, including a main frame 20, on which are arranged a furrow opener 11, a seed spotter 12, a soil cover 14, a water tank 3, a fertilizer tank 2, a seeding box 8, a control box 5, a power pump 19 and a peristaltic pump 16. The water tank 3, the fertilizer tank 2, the power pump 19 and the peristaltic pump 16 are connected through the first pipeline 22, the seed box 8 is connected with the second pipeline 7, the first pipeline 22 and the second pipeline 7 merge and are connected with the material conveyor 13, the material conveyor 13 is connected with the seeding device 12, the water in the water tank 3 and the fertilizer in the fertilizer tank 2 enter the material conveyor 13 through the power pump 19 and the peristaltic pump 16, and are mixed with the seeds discharged by the seed box 8 in the material conveyor 13, and then enter the seeding device 12 under the drive of the material conveyor 13; the control box 5 is respectively communicated with the peristaltic pump 16 and the seed box 8 to control the seeding frequency of the seed box 8 to be consistent with the frequency of the peristaltic pump 16 conveying the water-fertilizer mixture.

[0029] The planter can be installed on a traction device (such as a tractor, etc.) for use; it can also be used alone. The fertilizer in the fertilizer box 2 can be liquid fertilizer. When sowing small-seed crops such as rapeseed, sesame, and flax, the seeder moves forward and the furrow opener 11 opens a furrow on the land. At the same time, water is pumped out from the water tank 3 and fertilizer is pumped out from the fertilizer tank 2 under the action of the power pump 19, and then mixed in the first pipeline 22 to form a water-fertilizer mixture, which flows through the power pump 19 and the peristaltic pump 16 in turn. The peristaltic pump 16 intermittently transports the water-fertilizer mixture and transports it to the material conveyor 13. During this period, seeds are discharged from the seed box 8 and enter the material conveyor 13 through the second pipeline 7. After the seeds and the water-fertilizer mixture are mixed in the material conveyor 13, they are transported by the material conveyor 13 into the seeding device 12, and then enter the opened furrow through the seeding device 12. Then the soil covering device 14 pushes the soil turned out by the furrow opener when opening the furrow back into the furrow to cover the mixture of seeds, water and fertilizer. During this period, the control box 5 controls the seeding frequency of the seeding box 8 to be consistent with the frequency of the peristaltic pump 16 conveying the water-fertilizer mixture. The control box 5 controls the peristaltic pump 16 to feed intermittently, conveying a certain amount of water-fertilizer mixture each time. The seeding box 8 also seeds intermittently, discharging a certain amount of seeds (one or more seeds) each time; that is, each time the seeding box 8 discharges seeds into the material conveyor 13, the peristaltic pump 16 conveys the water-fertilizer mixture into the material conveyor 13 to mix with the seeds, and then the mixture of seeds, water and fertilizer enters the groove through the seeding device 12.

[0030] The present invention can complete the construction operations such as trenching, fertilizing, watering, sowing, and covering soil at one time when sowing small-grain crops, thereby improving the sowing efficiency and reducing the labor intensity of multiple operations required in the prior art; the water-fertilizer mixture is intermittently and quantitatively transported by the peristaltic pump 16, and the seed box 8 and the peristaltic pump 16 are controlled by the control box 5 to work in coordination, which can improve the water utilization efficiency while achieving precise sowing.

[0031] Specifically, the control box 5 is provided with a controller and related circuits, and the controller can be a single chip microcomputer, a custom chip, a PLC, etc. The seeding box 8 can be driven by a first motor, and the peristaltic pump 16 can be driven by a second motor. The controller is connected to the first motor and the second motor in communication, and the first motor and the second motor are controlled to make the seeding box 8 and the peristaltic pump 16 work at the same frequency and work in coordination. The main frame 20 can be provided with a left side mounting plate 18 and a right side mounting plate 9, the water tank 3 and the fertilizer tank 2 are arranged on the left side mounting plate 18, and the seeding box 8 can be arranged on the right side mounting plate 9.

[0032] Optionally, the material conveyor 13 is an air amplifier, and the material conveyor 13 is connected to a compressed air source.

[0033] The material conveyor 13 may be a structure similar to an air amplifier, and the material conveyor 13 has an inlet, an outlet and an air inlet, and the air inlet is connected to the air source. After the seeds and the water-fertilizer mixture enter the material conveyor 13 from the inlet, they are blown out from the outlet into the seeding device 12 under the action of air pressure, and then enter the groove. By specifically setting the length of the first pipeline 22 and the second pipeline 7, the seeds and the water-fertilizer mixture can be intersected and mixed at the same time in the material conveyor 13.

[0034] Of course, a buffer space may also be provided in the material conveyor 13, such as a platform or a groove with a smooth transition, so that the seeds or the water-fertilizer mixture will not leave the buffer space by itself due to gravity or inertia, but will directly flow out from the outlet into the seeding device 12, and the air source is required to provide power to enter the seeding device 12. The material conveyor 13 may be provided with a first solenoid valve on the pipeline connected to the air source, and the first solenoid valve is connected to the control box 5 in communication, and the control box 5 controls the first solenoid valve to be switched on and off at a certain frequency to provide power to the material conveyor 13. In this way, when the seeds and the water-fertilizer mixture cannot enter the material conveyor 13 completely synchronously, the one that arrives first can also wait in the buffer space for the other party to arrive and mix, and then be blown into the seeding device 12 by the air source.

[0035] Optionally, the air source is an air compressor 10 , and the air compressor 10 is disposed on the main frame 20 , and specifically can be disposed on the right placement plate 9 .

[0036] Optionally, a power box 6, a driving wheel 15, a driven wheel 21 and a handle 1 are also provided on the main frame 20. The power box 6 is transmission-connected to the driving wheel 15 and drives the driving wheel 15 to rotate.

[0037] The power box 6 may be provided with a third motor, which is connected to the driving wheel 15 by transmission, specifically by belt transmission. The third motor can drive the driving wheel 15 to rotate, thereby driving the seed drill as a whole to move, wherein the driven wheel 21 plays an auxiliary role in operation. In this case, the seed drill can be used alone, and the seed driller can hold the handle 1, push the seed drill forward and sow, and the presence of the third motor can save the seed driller more effort.

[0038] Optionally, the power box 6 is in communication connection with the control box 5. The control box 5 controls the forward speed of the seeder by controlling the power box 6, and controls the sowing interval and sowing density by controlling the forward speed, seeding rate and discharge rate of the water-fertilizer mixture of the seeder.

[0039] Alternatively, see Figure 4 The first pipeline 22 includes a first branch 203, a second branch 302 and a three-way valve 202. The fertilizer tank 2 is connected to the three-way valve 202 through the first branch 203, the water tank 3 is connected to the three-way valve 202 through the second branch 302, and the three-way valve 202 is connected to the power pump 19; a second flow control valve 201 is provided on the first branch 203, and a first flow control valve 301 is provided on the second branch 302.

[0040] By setting the first flow control valve 301 and the second flow control valve 201, the operator can accurately adjust the flow of water and fertilizer according to the sowing requirements, thereby ensuring that the output water-fertilizer mixture has an accurate ratio. The first flow control valve 301 and the second flow control valve 201 can also be connected to the control box 5 for communication, and the control box 5 can control the on-off and flow of the first flow control valve 301 and the second flow control valve 201.

[0041] Optionally, an accumulator 17 is provided between the power pump 19 and the peristaltic pump 16 , and the accumulator 17 is used to stabilize the output pressure of the water-fertilizer mixture output by the power pump 19 .

[0042] Alternatively, see Figure 2The peristaltic pump 16 includes a rotating shaft 1602 and a rubber hose 1603. The rubber hose 1603 is provided with a water inlet 1604 and a water outlet 1605. The first rolling wheel 1601 and the second rolling wheel 1606 are provided at both ends of the rotating shaft 1602. Every time the rotating shaft 1602 rotates one circle, the first rolling wheel 1601 and the second rolling wheel 1606 are driven to rotate and squeeze the rubber hose 1603 to complete a suction and discharge of the peristaltic pump 16. The control box 5 controls the intermittent rotation frequency of the rotating shaft 1602 to control the frequency of the peristaltic pump 16 conveying the water-fertilizer mixture.

[0043] When the rotating shaft 1602 rotates, the first rolling wheel 1601 and the second rolling wheel 1606 squeeze the rubber hose 1603, thereby realizing a single suction and discharge process of the peristaltic pump 16. This mechanical squeezing method ensures accurate measurement and stable delivery of the liquid. This design enables the peristaltic pump to flexibly suck and discharge liquid.

[0044] The peristaltic pump 16 achieves intermittent and quantitative discharge of the water-fertilizer mixture by intermittently driving the rotating shaft 1602. This control method enables the seed drill to accurately control the discharge amount and discharge timing of the water-fertilizer mixture according to the seeding requirements.

[0045] Cooperation with the seeding device and material conveyor: The water-fertilizer mixture discharged by the peristaltic pump is sent to the material conveyor 13, and together with the seeds, it obtains power through the material conveyor 13 and is accurately discharged into the soil through the seeding device 12. This design ensures the accurate ratio of water, fertilizer and seeds and uniform sowing, and improves sowing efficiency and crop growth quality.

[0046] Optionally, the seeding box 8 includes a shell 805, in which a partition 808 with a notch on the top is arranged, the partition 808 divides the shell 805 into a seeding area and a seed guiding area, a seeding disk 809 is rotatably arranged in the seeding area, the seeding disk 809 is circumferentially provided with a plurality of seeding spoons 801, a seed guiding wheel 802 is rotatably arranged in the seed guiding area, and a plurality of seed guiding grooves 807 are circumferentially arranged on the seed guiding wheel 802; when the seeding disk 809 rotates, the seeding spoon 801 on the seeding disk 809 digs seeds from the seeding area, and when it rotates to the top of the partition 808 with the seeds, the seeds are transported to the seed guiding groove 807 through the notch, and when the seed guiding wheel 802 rotates, it drives the seeds in the seed guiding groove 807 to move to the seed dropping port 804 for seeding; the control box 5 controls the seeding frequency of the seeding box 8 by controlling the rotation frequency of the seeding disk 809 and the seed guiding wheel 802.

[0047] During the seeding process, the seeds first fall stably into the seeding area in the seeding box 8 by their own gravity for pre-filling. The first motor drives the main shaft 806 of the seeding box 8 as a power source to drive the seeding disc 809 to perform precise rotational motion. When the seeding spoon 801 carries the seeds and rotates to the top, the seeds escape from the seeding spoon under the action of gravity, and accurately fall into the seeding groove 807 of the seed guide wheel 802 through the gap of the partition 808. At the same time, the seed guide wheel 802 rotates under the driving action of the main shaft 806 to ensure that the seeds are smoothly and accurately transported to the seeding port 804. The seeding port 804 is connected to the material conveyor 13 through the second pipeline 7. After mixing with the water-fertilizer mixture, it enters the seeding device 12 and is transported to the groove to ensure that the seeds are evenly arranged and distributed in the soil, and to achieve precise sowing.

[0048] Optionally, a water replenishment pump 4 is further provided on the main frame 20 , and the water replenishment pump 4 is connected to the water tank 3 , and the water replenishment pump 4 is used to replenish water to the water tank 3 .

[0049] In this way, when the water tank 3 is short of water, water can be pumped from a water source by the water replenishment pump 4 to replenish the water tank 3 .

[0050] The working principle of the present invention is as follows: the peristaltic pump controls the intermittent and quantitative discharge of the water-fertilizer mixture to the seeding device. The water-fertilizer mixture and seeds obtain power through the material conveyor on the seeding device and are discharged into the soil together, achieving the effect of precise sowing of water, fertilizer and seeds. The seeding box can ensure uniform seeding, and the accumulator stabilizes the output pressure of the power pump to the water-fertilizer mixture. The control box controls the seeding frequency of the seeding box to be consistent with the frequency of the peristaltic pump conveying the water-fertilizer mixture, so that each row of seeds corresponds to the delivery of the water-fertilizer mixture. The control box can also match the seeding frequency of the seeding box with the forward speed of the seeder to control the seeding density of the seeds. In this way, the precise sowing of water, fertilizer and seeds is achieved, multiple operation processes are reduced, resource waste is reduced, and time costs are saved.

[0051] The above embodiments are only descriptions of the preferred implementation modes of the present invention, and are not intended to limit the specific implementation scope of the present invention.
