Description

Technical Field

[0001] The invention relates to the field of agricultural planting equipment, and in particular to a millet film-covered precise hole-seeding device. Background Art

[0002] With the advancement of agricultural modernization, precision agriculture technology has gradually become an important means to improve crop yield and quality. As an important food crop, millet is particularly suitable for planting in arid and semi-arid areas. The optimization of its production methods is crucial to ensuring food security. In recent years, film covering technology and hole sowing technology have been widely used in the production of millet. Film covering technology is to reduce soil moisture evaporation, increase soil temperature, and improve the growth environment of crops by covering the soil surface with a thin film, thereby achieving the purpose of increasing yield. The hole sowing technology is to sow seeds by drilling holes on the soil surface so that the seeds can take root and germinate at the appropriate depth and position. This method helps to improve the germination rate of seeds, the uniformity of seedling emergence, and the stress resistance of crops.

[0003] Although the current millet mulching and hole-seeding technologies have achieved good application results, there are still some problems. First, in the process of fertilization, the amount of fertilizer put in by the traditional mulching and hole-seeding device is often difficult to accurately control, and it is easy to have excessive or insufficient fertilizer, which not only wastes precious resources, but also may affect the growth of crops and the long-term fertility of the soil. In addition, in some soil types, especially those with high viscosity, the seed delivery pipeline is often blocked during the sowing process, which will lead to uneven sowing or interrupted sowing, affecting the sowing efficiency and crop germination.

[0004] To this end, those skilled in the art have proposed a millet film-covered precision hole-seeding device to solve the above problems. Summary of the invention

[0011] Preferably, the transmission assembly includes two synchronous wheels, one of which is fixedly connected to one end of the rotating rod, and the other is fixedly connected to the outside of the film punching machine, and the two synchronous wheels are connected by a synchronous belt.

[0012] Preferably, a pump body is installed on one side of the top of the liquid storage tank, the output end of the pump body is fixedly connected to a first connecting pipe, and the input end of the pump body is fixedly connected to a second connecting pipe.

[0013] Preferably, one end of the second connecting pipe is connected to the top of the liquid storage tank, and the other end of the first connecting pipe is connected to one side of the top of the installation box.

[0014] A method for using a millet film-covered precise hole-seeding device comprises the following steps:

[0015] Step 1: Place millet seeds in two storage boxes, then start the machine body, and as the machine body moves on the land, place the film roller to cover the land, then start the drive motor on the outside of the fixed cylinder, the drive motor drives the rotating rod to rotate, the rotating rod drives one of the synchronous wheels to rotate, the synchronous wheel drives the synchronous wheel on the outside of the film punching machine to rotate under the action of the synchronous belt, and then drives the film punching machine to rotate, so that the film is punched;

At this time, start the motor outside the quantitative box, and the drive turntable is driven by the motor to rotate, which further drives the fixed block to rotate eccentrically, so that the fixed block rotates eccentrically along the outer surface of the drive turntable. Since the fixed block moves along the movable groove inside the movable frame, it drives the movable frame to reciprocate left and right, and then drives the rubber piston to reciprocate, discharges the fertilizer inside the cavity from the transport pipe into the spray pipe, and finally sprays it out through the pulse nozzle.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Please refer to the attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides a millet film-covered precise hole-seeding device, comprising a machine body 1, a liquid storage tank 7 is installed on the top side of the machine body 1, a quantitative box 603 is installed on the top side of the liquid storage tank 7, a mounting box 609 is fixedly connected to the top side of the quantitative box 603, two adjustment slots 612 are sequentially provided on the bottom side of the mounting box 609, an inner wall of the mounting box 609 is elastically connected to a movable plate 611 through a tension spring 610, a motor is installed on the outer side of the quantitative box 603, and the driving end of the motor passes through the outer surface of the quantitative box 603. The surface is fixedly connected to a driving turntable 604, a fixed block 606 is fixedly connected to the external eccentric part of the driving turntable 604, the inner wall of the metering box 603 is slidably connected to a movable frame 605, a connecting rod 607 is fixedly connected to the middle part of the outer side of the movable frame 605, one end of the connecting rod 607 is fixedly connected to a rubber piston 608, one side of the bottom end of the metering box 603 is connected to a transport pipe 601, the other end of the transport pipe 601 is connected to a spray pipe 602, and a plurality of pulse nozzles are fixedly connected to the outer surface of the spray pipe 602 at equal intervals.

[0032] Specifically, the body 1, as the frame part of the device, is the support platform for all components, ensuring the fixation of each functional component and the stability of operation. A liquid storage tank 7 is installed on one side of the top of the body 1 for storing fertilizer liquid. The liquid storage tank 7 is the storage source of fertilizer in the device. When fertilizing, the fertilizer in the liquid storage tank 7 is extracted by the pump body 801 for subsequent operation. The quantitative box 603 is the core component of the fertilization part of the device, which is mainly used to store and control the delivery amount of fertilizer. The top side of the quantitative box 603 is fixedly connected to the installation box 609. Two regulating grooves 612 are provided on one side of the bottom of the installation box 609. The two regulating grooves 612 respectively guide the fertilizer to flow into the quantitative box 603 and control the flow of the fertilizer.

[0033] Left regulating groove 612: Fertilizer first enters the cavity inside the quantitative box 603 through the left regulating groove 612. At this time, the inflow of fertilizer is driven by the delivery pressure of the pump body 801, and the regulating groove 612 plays a role in guiding the fertilizer to enter the quantitative box 603.

[0034] Right regulating groove 612: When the cavity of the quantitative box 603 is filled, the fertilizer will flow out through the right regulating groove 612, pushing the movable plate 611 to move to the left. The movement of the movable plate 611 ensures that the outlet of the quantitative box 603 is effectively blocked, preventing excessive fertilizer from flowing out, and ensuring accurate control of the fertilization amount.

[0035] A motor is installed on the outside of the quantitative box 603, and the function of the motor is to drive the mechanical action in the subsequent fertilization process. The driving end of the motor penetrates the outer surface of the quantitative box 603 and is fixedly connected to the driving turntable 604. The motor drives the eccentric rotation of the driving turntable 604 by rotating it. The characteristic of eccentric rotation is the eccentric position of a fixed block 606 on the turntable. As the turntable rotates, the fixed block 606 will also make eccentric movement. The movable frame 605 is slidably connected to the inner wall of the quantitative box 603, and can make left and right reciprocating motions in the internal movable groove according to the eccentric rotation of the driving turntable 604. The movement of the movable frame 605 directly drives the connecting rod 607 to move accordingly. A rubber piston 608 is fixedly connected to one end of the connecting rod 607. The combination of the connecting rod 607 and the movable frame 605 enables the fertilization device to run smoothly along a certain path, avoiding fertilization errors caused by unstable devices. The transport pipe 601 is connected to one side of the bottom end of the quantitative box 603, and is responsible for transporting the fertilizer in the quantitative box 603 to the spray pipe 602. As a transport channel, the transport pipe 601 has high fluidity, ensuring that the fertilizer will not be blocked due to pipeline problems, thereby ensuring the continuity and stability of the fertilization process. The spray pipe 602 is responsible for guiding the fertilizer from the transport pipe 601 to a plurality of pulse nozzles. A plurality of pulse nozzles are evenly fixed on the outer surface of the spray pipe 602, and these nozzles periodically spray fertilizer according to the set spraying frequency and flow rate. The design of this pulse nozzle can effectively distribute the fertilizer evenly into the soil, ensuring that each sowing point can obtain accurate and sufficient fertilizer, thereby promoting the growth of millet roots and optimizing the germination environment of crops.

[0036] During the millet hole sowing process, when the pump body 801 is started, the fertilizer enters the first connecting pipe 802 from the liquid storage tank 7 through the second connecting pipe 803, and then enters the quantitative box 603 through the first connecting pipe 802. The fertilizer enters the cavity of the quantitative box 603 through the left regulating groove 612. When the cavity is filled, the fertilizer pushes the movable plate 611 to block the discharge port through the right regulating groove 612. Then, the motor drives the turntable 604 to rotate, driving the fixed block 606 to rotate eccentrically. The fixed block 606 moves along the movable groove of the movable frame 605, driving the movable frame 605 to reciprocate left and right, thereby pushing the rubber piston 608 to transport the fertilizer to the liquid spray pipe 602 through the transport pipe 601, and accurately spraying it to the sowing point through the pulse nozzle. The device realizes precise quantitative fertilization and automatic sowing, which not only improves the utilization rate of fertilizers and reduces resource waste, but also effectively guarantees the sowing quality and germination effect of millet, providing an efficient and environmentally friendly solution for modern agriculture.

[0037] The outer surface of the movable plate 611 is slidably connected to the inner wall of the installation box 609, a control valve is installed on the outer side of the transport pipe 601, a movable groove is opened inside the movable frame 605, and the fixed block 606 is movably connected inside the movable groove.

[0038] Specifically, the seeds located inside the storage box 201 enter the fixed cylinder 202 along the through slot 206 at the top under the action of their own gravity. This process completely relies on the gravity of the seeds and the guidance of the through slot 206. The seeds can smoothly enter the fixed cylinder 202 through the through slot 206 without accumulation or obstruction. The drive motor 203 is installed on the outside of the fixed cylinder 202 and is connected to the rotating rod 204 through the output end. The start of the motor drives the rotating rod 204 to rotate, thereby driving the multiple dredging plates 205 fixedly connected thereto to rotate. The rotating rod 204 can be a continuous rotating mechanism and has sufficient speed and torque to ensure that the dredging plates 205 can operate effectively. Multiple dredging plates 205 are installed on the outer surface of the rotating rod 204, and they generate rotational motion through the rotation of the rotating rod 204. As the dredging plates 205 rotate, they interact with the seeds inside the fixed cylinder 202, thereby achieving stirring and pushing of the seeds. The dredging plates 205 are designed to allow them to efficiently penetrate the seed accumulation area, avoid seed accumulation or blockage, and ensure that the seeds can be smoothly discharged through the bottom slot 206 of the fixed cylinder 202. The outer surface of the fixed cylinder 202 is provided with two slots 206 at equal intervals, and the seeds are discharged through these slots 206. The rotation of the dredging plates 205 can not only stir the seeds, but also guide the seeds to be discharged along the direction of the slots 206, avoiding the blockage caused by the accumulation of seeds during storage or transportation.

[0039] A plurality of film punchers 3 are installed on one side of the bottom of the machine body 1, and the plurality of film punchers 3 are fixedly connected in sequence. A film placing roller 4 is installed on the middle side of the bottom of the machine body 1, and the outer side of the film puncher 3 is connected to the outer side of the fixed cylinder 202 through a transmission assembly. The transmission assembly includes two synchronous wheels, one of which is fixedly connected to one end of the rotating rod 204, and the other is fixedly connected to the outer side of the film puncher 3, and the two synchronous wheels are connected through a synchronous belt 5.

[0040] Specifically, the film puncher 3 is designed to perform precise punching operations on film materials to meet the needs of subsequent processing or use. Multiple film punchers 3 are fixedly connected in sequence along the side of the bottom of the body 1 and remain stable during operation to ensure that the working state of each film puncher 3 is synchronized to prevent quality problems caused by asynchrony. The function of the film placing roller 4 is to effectively support and convey the film material to be processed to ensure that the film material can be smoothly transferred to the working position of the film puncher 3. The design of the film placing roller 4 takes into account the tension and stability of the film, and can maintain a certain pressure during operation to prevent the film material from being affected by loose or uneven pressure and affecting the processing effect.

[0041] A pump body 801 is installed on one side of the top of the liquid storage tank 7, and the output end of the pump body 801 is fixedly connected to a first connecting pipe 802, and the input end of the pump body 801 is fixedly connected to a second connecting pipe 803. One end of the second connecting pipe 803 is connected to the top of the liquid storage tank 7, and the other end of the first connecting pipe 802 is connected to one side of the top of the installation box 609.

[0042] Specifically, the pump body 801 starts working first, and the fertilizer in the liquid storage tank 7 is sucked into the pump body 801 through the second connecting pipe 803. After being processed by the pump body 801, the sucked fertilizer is transported to the target location by connecting to the first connecting pipe 802, and the fertilizer flows into the installation box 609 through the first connecting pipe 802.

[0043] A method for using a millet film-covered precise hole-seeding device comprises the following steps:

[0044] Step 1, millet seeds are placed in two storage boxes 201, and then the machine body 1 is started. As the machine body 1 moves on the land, the film roller 4 is placed to cover the land with film, and then the drive motor 203 outside the fixed cylinder 202 is started. The drive motor 203 drives the rotating rod 204 to rotate, and the rotating rod 204 drives one of the synchronous wheels to rotate. The synchronous wheel drives the synchronous wheel outside the film punching machine 3 to rotate under the transmission action of the synchronous belt 5, and then drives the film punching machine 3 to rotate, so that the film is punched;

[0045] Step 2: The seeds in the storage box 201 enter the interior of the fixed cylinder 202 through the top slot 206 under the action of their own gravity. At this time, the rotation of the rotating rod 204 drives the multiple dredging plates 205 to rotate, and the seeds are discharged from the bottom slot 206 to avoid blockage during the seed hole sowing process;

[0046] Step 3: During the seed hole sowing process, the pump body 801 is started to allow the fertilizer in the liquid storage tank 7 to enter the first connecting pipe 802 through the second connecting pipe 803, and then enter the installation box 609 through the first connecting pipe 802. At this time, the fertilizer enters the cavity inside the quantitative box 603 through the left regulating groove 612. When the cavity is filled, the fertilizer passes through the right regulating groove 612, pushing the movable plate 611 to move to the left, blocking the discharge port of the first connecting pipe 802. At this time, the outer side of the quantitative box 603 is started. The motor drives the driving turntable 604 to rotate, and further drives the fixed block 606 to rotate eccentrically, so that the fixed block 606 rotates eccentrically along the outer surface of the driving turntable 604. Since the fixed block 606 moves along the movable groove inside the movable frame 605, it drives the movable frame 605 to reciprocate left and right, and then drives the rubber piston 608 to reciprocate, so that the fertilizer inside the cavity is discharged from the transport pipe 601 into the spray pipe 602, and finally sprayed out through the pulse nozzle.

[0047] In summary: the present invention can reduce soil moisture loss and improve soil moisture retention through reasonable fertilization design on the basis of film covering, effectively improve the seed germination environment, promote root growth, and enhance the stress resistance and early growth potential of crops. At the same time, the quantitative fertilization function can ensure that each sowing point obtains accurate fertilizer supply, avoiding the phenomenon of excessive or insufficient fertilizer in traditional fertilization methods, and improving fertilizer utilization.
