Technical Field
[0001] This utility model relates to the field of agricultural planting technology, and in particular to a pneumatically adjustable Artemisia seed fertilizer uniform sowing machine. Background Technology
[0002] Artemisia argyi, also known as mugwort, is a perennial herb of the Asteraceae family. In the process of planting Artemisia argyi seeds, appropriate equipment is needed to sow the seeds and fertilizer.
[0003] Traditional artemisia planting equipment is relatively simple, and artemisia seeds and fertilizers are sown separately. Spreading equipment or manual spreading is used to sow fertilizer or artemisia seeds at the planting location in the field. This production method has a very low degree of mechanization. In addition, the artemisia seeds are mostly small and it is difficult to find suitable equipment for sowing, resulting in high costs and low practicality of mechanized planting. Summary of the Invention
[0004] The technical problem this utility model aims to solve is that traditional mugwort planting equipment is relatively simple, and mugwort seeds and fertilizers are sown separately. Spreading equipment or manual spreading is used to sow fertilizers or mugwort seeds at the planting location in the farmland. This production method has a very low degree of mechanization. At the same time, since the mugwort seeds are mostly small, it is difficult to have the corresponding matching equipment for sowing, resulting in high costs and low practicality of mechanized planting.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a pneumatically adjustable Artemisia seed-fertilizer uniform seeder, including a support mechanism, an adjustable seed-fertilizer adsorption device, a seed-fertilizer movement path selection mechanism, a transmission mechanism, an air pressure supply mechanism, and an adjustable trenching and covering mechanism; the two adjustable seed-fertilizer adsorption devices are fixed to the upper rear of the device body through internal parts of the support mechanism, the seed-fertilizer movement path selection mechanism is fixed at the seed discharge channel outlet of the adjustable seed-fertilizer adsorption device, and its front and rear end pipes are connected to the adjustable trenching and covering mechanism, and the Artemisia seeds or fertilizer inside are transported through the adjustable trenching and covering mechanism. The delivery pipeline reaches the lower end of the furrow opener, ensuring that the Artemisia argyi seeds and fertilizer are evenly distributed in the same longitudinal plane within the furrow. The engine of the transmission mechanism is located in the chassis of the support mechanism. Through bevel gears, shafts, and other components inside the transmission mechanism, a portion of the power is output to the second Artemisia argyi seed adsorption plate and the first fertilizer adsorption plate, which mesh with the adjustable seed-fertilizer adsorption device, thereby driving the movement of the Artemisia argyi seeds and fertilizer. Simultaneously, another portion of the power from the transmission mechanism is transmitted to the wheel axle, enabling the overall movement of the machine. The negative pressure port of the air pressure supply mechanism connects to the adjustable seed-fertilizer adsorption device via a pipeline and an internal air pressure transmission mechanism. The air pressure port located at the center of the device is connected to control the negative pressure inside the adjustable seed-fertilizer adsorption device. Because the negative pressure chamber inside the adjustable seed-fertilizer adsorption device is relatively small, the negative pressure required to create a near-vacuum is small, meaning the required fan power is low. Furthermore, the number of working rings inside the adjustable seed-fertilizer adsorption device can be adjusted via a flexible air ring regulating device, thereby regulating the seeding rate. The positive pressure port of the air pressure supply mechanism is connected to the seed and fertilizer delivery pipe at the front end of the seed-fertilizer movement path selection mechanism via a pipe, thus accelerating the descent of the seed and fertilizer through the blowing action of positive pressure air. The adjustable trenching and covering mechanism on both the front and rear sides features a symmetrical design. The working parts, such as the trencher, covering device, and individual leveling plate, are adjusted by the adjustment device on the adjustable trenching and covering mechanism to select the working mode. That is, when moving forward, the covering device of the rear adjustable trenching and covering mechanism is lifted, and the trencher and each leveling plate together form a leveling support plate to level the ground after the front has been covered with soil. Ultimately, it realizes low-power fan control for multiple rows of seed and fertilizer discharge, and the working mode is reciprocating operation. It also realizes integrated operation of trenching, covering, and leveling, achieving the goal of cost reduction and efficiency improvement.
[0006] Preferably, the support mechanism includes: an adjustable seed fertilizer adsorption device support plate, a first seed disc gear support shaft, a transmission chain, a rear wheel, a first frame support plate, a frame support plate body, a first front frame support plate, a front wheel, a front axle body, a frame front baffle, a left sprocket drive shaft, a second front frame support plate, a second frame support plate, a right sprocket drive shaft, a rear baffle, a second seed disc gear support shaft, and a middle support plate. The frame front baffle, frame support plate body, and first frame support plate are welded around the perimeter. The first and second frame support plates are horizontally welded above the welded frame. Two first front frame support plates and one second front frame support plate are welded and fixed above the frame front baffle. A middle support plate is flush with the first frame support plate and welded and fixed above the device. The four adjustable seed fertilizer adsorption device support plates are adjusted to the same height as the first frame support plate. The adjustable seed fertilizer adsorption device support plate is welded to the corresponding position on the middle support plate. The fixed position of the adjustable seed fertilizer adsorption device support plate has a hole to prevent bearings. The middle of the two adjustable seed fertilizer adsorption device support plates on the left and the two adjustable seed fertilizer adsorption device support plates on the right are fixed and can rotate through the bearings. Similarly, the frame support plate body and the corresponding plate on the opposite side have holes to install bearings, so that the left sprocket drive shaft and the right sprocket drive shaft can be fixed and can rotate.
[0007] The effects achieved by the above components are as follows: the support mechanism, through the precise layout of support plates and bearings, ensures the stable operation of the adjustable seed fertilizer adsorption device and transmission system, optimizes the support structure, and improves the overall robustness and durability of the equipment. This design effectively enhances the stability of the equipment and ensures the precise coordination of each component during operation and long-term work.
[0008] Preferably, the adjustable seed fertilizer adsorption device includes: a negative pressure air chamber, an Artemisia argyi seed fertilizer filling box, a return spring body, a first negative pressure port, a seed fertilizer carrying tray, a right-side fertilizer movement box, an air chamber effective volume adjustment bolt, a first fertilizer filling box, a first Artemisia argyi seed filling box, a second Artemisia argyi seed filling box, a second fertilizer filling box, a return spring internal connecting bolt, an air chamber effective volume flexible adjustment ring, a first air chamber effective volume rigid auxiliary adjustment ring, a left-side seed adsorption tray, a second air chamber effective volume rigid auxiliary adjustment ring, a second Artemisia argyi seed adsorption tray, and a third... The system consists of two fertilizer adsorption discs, an external discharge channel for Artemisia argyi seed fertilizer, an internal discharge outlet for the seeds (the starting point of adsorption and transportation), and a second Artemisia argyi seed fertilizer filling box. The first and second Artemisia argyi seed fertilizer filling boxes are symmetrically distributed and fixed in a set position by four adjustable seed fertilizer adsorption device support plates. At this time, a feeding box with four inlets is fixedly connected above the two filling boxes, and two pairs of second Artemisia argyi seed adsorption discs and second fertilizer adsorption discs are connected to the left and right sides. At this time, each adsorption disc is equipped with a flexible adjustment ring for the effective volume of the air chamber on its outer side and is filled by two pairs of Artemisia argyi seed fertilizer. The box, the right-side fertilizer movement box, and four filling boxes are fastened in pairs to the Artemisia argyi seed fertilizer filling box and the second Artemisia argyi seed fertilizer filling box by screws. The flexible adjustment ring of the effective volume of the air chamber contains a first rigid auxiliary adjustment ring of the effective volume of the air chamber, and the flexible adjustment ring of the effective volume of the air chamber has a hole. The internal connecting bolt of the return spring is threadedly connected to the first rigid auxiliary adjustment ring of the effective volume of the air chamber. The return spring body is connected above the internal connecting bolt of the return spring, and the end of the return spring body is connected to and fixed to the effective volume adjustment ring of the air chamber. At the end of the bolt, the effective volume adjustment bolt of the air chamber is raised and lowered through threaded holes in the two pairs of Artemisia seed fertilizer filling boxes and the right fertilizer movement box. Through the return spring body and the rigid auxiliary adjustment ring of the effective volume of the air chamber, the force is transmitted to achieve the opening of the flexible adjustment ring of the effective volume, thereby changing the effective volume of the negative pressure chamber, ultimately adjusting the number of working hole rings and the number of dropping materials. The two pairs of adsorption discs are driven by gears meshing with the gear support shaft of the second row of seed discs to transport the adsorbed seed fertilizer.
[0009] The effects achieved by the above components are as follows: the adjustable seed fertilizer adsorption device achieves precise adjustment of the seeding amount through wind pressure control and spring return mechanism, reduces the power requirement of the fan, and improves the accuracy and stability of seeding. The device makes the distribution of seed fertilizer more uniform, ensuring the high efficiency and low energy consumption of seeding operations.
[0010] Preferably, the seed fertilizer movement path selection mechanism includes: a first feeding channel, a second feeding channel, a seed fertilizer movement path selector, a seed fertilizer rear-end conveying pipe, and a seed fertilizer front-end conveying pipe. The first feeding channel is connected to the Artemisia argyi seed fertilizer outflow channel, and the second feeding channel is sleeved with the first feeding channel. The seed fertilizer movement path selector has a circular hole in the middle that is coaxially engaged with the circular shaft at the center of the seed fertilizer movement path selection mechanism and can rotate around it. The upper ends of the seed fertilizer rear-end conveying pipe and the seed fertilizer front-end conveying pipe are respectively connected to the front and rear ends of the second feeding channel, and the ends are connected to the front and rear adjustable trenching and covering mechanism. By rotating and changing the seed fertilizer movement path selector, the seed fertilizer can be selected to go to the seed fertilizer rear-end conveying pipe or the seed fertilizer front-end conveying pipe, so that the movement direction of the seed fertilizer is consistent with the machine operation direction.
[0011] The effects achieved by the above components are as follows: the motion path selector can adjust the flow path of the seed fertilizer as needed, optimize the sowing process, and the flexible path selection reduces the complexity of the machine and improves the ease of operation. This design enables the seeder to quickly adjust the sowing direction according to different operational needs, thereby improving operational efficiency.
[0012] Preferably, the transmission mechanism includes: a first fertilizer adsorption plate, a left first meshing gear, a middle transmission gear, a left second meshing gear, a middle transmission upstream gear, a left front axle, a first middle transmission upstream transmission shaft, bevel gears, a first vehicle body motion transmission shaft, a right front axle, a first gear shifter, a second middle transmission upstream transmission shaft, a second vehicle body motion transmission shaft, a transmission chain body, a rear axle, and an engine. The engine is fixed to the chassis and transmits power to the front wheels through the first vehicle body motion transmission shaft, the right front axle, and solid lines. It also transmits vehicle body power to the rear end through the first gear shifter and the second vehicle body motion transmission shaft, thereby realizing the forward and reverse movement of the vehicle body. The three bevel gears drive the first middle transmission upstream transmission shaft and the second middle transmission upstream transmission shaft to rotate, thereby driving the two middle transmission upstream gears to rotate. Through the chain, The two central transmission gears on the left and right transmit force to the upstream transmission shafts of the first and second central transmissions, which in turn drive the four central transmission gears to rotate and mesh with the corresponding first fertilizer adsorption plate, second artemisia seed adsorption plate, left seed adsorption plate, and second fertilizer adsorption plate, thereby driving them to rotate.
[0013] The effects achieved by the above components are as follows: through precise gear transmission and multi-point power transmission system, the movement of Artemisia argyi seeds and fertilizer is synchronized, transmission efficiency is improved, energy loss is reduced, and the smooth operation of the machine is realized. This transmission system ensures that the equipment can withstand long-term operation without easily malfunctioning while working efficiently.
[0014] Preferably, the air pressure supply mechanism includes: a first negative pressure transmitter, a first positive pressure transmitter, a fan, a first negative pressure tee, a negative pressure bend, a second negative pressure transmitter, a second positive pressure transmitter, a positive pressure blowing pipe, a second negative pressure port, and a negative pressure pipeline. The fan is fixed to a corresponding position on the chassis. The negative pressure port of the fan is connected to the pipeline, the first negative pressure tee, and the negative pressure bend. At the same time, the upper ends of the first negative pressure tee and the negative pressure bend are respectively connected to the second negative pressure transmitter and the first negative pressure transmitter. Then, it is connected to the second negative pressure port through a flexible hose to transmit negative pressure. The positive pressure port of the fan is connected to the second positive pressure transmitter and the positive pressure blowing pipe through the positive pressure pipeline and the positive pressure bend. The positive pressure blowing pipe is connected to the rear conveying pipe to accelerate the falling of the Artemisia argyi seeds and fertilizer, thereby reducing the falling time.
[0015] The effects achieved by the above components are as follows: the negative and positive pressure systems of the fan provide strong airflow support for sowing, optimize the transport efficiency of seed fertilizer, reduce the material drop time by precisely controlling the airflow, improve the operating speed and accuracy, and the design of the wind pressure system significantly improves the operating efficiency of the seeder and reduces energy consumption, ensuring the long-term stable operation of the machine.
[0016] Preferably, the adjustable trenching and covering mechanism includes: a first rear-end rotating shaft, a front and rear-end bumper, a second rear-end rotating shaft, a rear-end leveling plate, a rear-end plow, a working mode adjustment rod, a covering disc body, a covering disc fixing shaft, a front-end plow, a front-end leveling plate, a first covering device fixing device, leveling plate connecting parts, a front-end rotating shaft, a second covering device fixing device, and a working mode adjustment handle. The front and rear bumpers are welded and fixed to the front and rear of the machine respectively through two connecting parts at the upper end of the front and rear bumpers. The front rotating shaft is fixed to the front and rear bumpers by connecting to the working mode adjustment rod. The working mode adjustment rod is fixedly connected to the front and rear baffles of the frame, and the working mode adjustment rod is internally connected to the rear baffle. The working mode adjustment handle, when rotated, causes the working mode adjustment rod to rotate around its upper rotation center, thereby driving the front-end rotating shaft connected to its end to rotate by a corresponding angle. The upper end of the first soil covering device is fitted and tightly fixed to the front of the front rotating shaft at an approximately square shaft. The lower end of the device is provided with a soil covering disc fixing shaft, which is fitted and fixed to the soil covering disc body. Bearings can also be installed on the soil covering disc fixing shaft to enable the soil covering disc body to roll during operation. The upper end of the leveling plate connecting part is connected to the front rotating shaft, and the lower end is connected to the upper protrusion of the front leveling plate, thereby fixing the front leveling plate. The front plow blade is fixed to the front and rear bumpers. The front and rear adjustable trenching and soil covering mechanisms are exactly the same.
[0017] The effect achieved by the above components is that the first soil covering device fixing device, the soil covering disc body, and the front leveling plate rotate accordingly with the rotation of the front shaft. The rotation of the front shaft is adjusted by the rotation adjustment handle on the working mode adjustment rod, and finally the rotation of the first soil covering device fixing device, the soil covering disc body, and the front leveling plate is controlled by rotating the adjustment handle. Meanwhile, since the soil-covering disc body is installed behind the front plow blade and in the same direction, and the front leveling plate and the front plow blade are installed alternately, when the front leveling plate is raised, the soil-covering disc body falls, so that only the front plow blade and the soil-covering disc body work, thereby realizing the trenching and soil-covering operations. At this time, by raising the rear soil-covering disc body and lowering the leveling plate, the rear leveling plate and the plow blade form an approximately sealed curved geometric cuboid, thereby performing soil-leveling operations on the soil pile covered at the front. Conversely, when the rear of the machine is working, the operation can be reversed, ultimately realizing the adjustability of the trenching and soil-covering mechanism. A pneumatic artemisia seed fertilizer uniform seeder can work in the forward and backward directions, avoiding circular turns.
[0018] The beneficial effects of this utility model are:
[0019] This invention controls the volume of the external negative pressure chamber of the adjustable seed fertilizer adsorption device, thereby enabling a small-power fan to meet the requirements of a large negative pressure, thus ensuring that the small-power fan adsorbs multiple rows of Artemisia argyi seeds and fertilizer.
[0020] By adjusting the flexible air ring inside the adjustable seed fertilizer adsorption device, the effective volume of the internal air pressure can be controlled, thereby controlling the effective number of seeds and fertilizers adsorbed inside. Furthermore, by designing an adsorption plate that meets the shape of Artemisia argyi seeds and fertilizer, the purpose of adsorbing two different materials at the same time can be guaranteed.
[0021] The adjustable trenching and covering mechanism at both ends can select the corresponding working parts according to the working direction of the vehicle body to achieve the goal of reciprocating trenching, covering, and leveling.
[0022] The seed fertilizer movement path selection mechanism selects the seed fertilizer movement path under the corresponding working conditions, thereby meeting the working requirements of reciprocating motion while avoiding small circular turns.
[0023] By defining the filling positions of mugwort seeds and fertilizer, the movement path of both is ensured throughout the entire process, thereby ensuring the determination of the ratio of the number of seeds and fertilizers at the same position in the final ditch. Attached Figure Description

[0043] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0045] Figures 1-2 The invention relates to a pneumatically adjustable Artemisia seed fertilizer uniform seeding machine, which includes a support mechanism 1, an adjustable seed fertilizer adsorption device 2, a seed fertilizer movement path selection mechanism 3, a transmission mechanism 4, an air pressure supply mechanism 5, and an adjustable trenching and soil covering mechanism 6.
[0046] Figures 1-12The two adjustable seed-fertilizer adsorption devices 2 shown are fixed to the upper rear of the entire device via internal parts of the support mechanism 1. The seed-fertilizer movement path selection mechanism 3 is fixed at the seed discharge channel outlet of the adjustable seed-fertilizer adsorption device 2. The pipes at the front and rear ends of the mechanism are connected to the adjustable ditching and covering mechanism 6, and the Artemisia argyi seeds or fertilizer inside the mechanism are transported to the lower end of the ditch opener through the internal transport pipes of the adjustable ditching and covering mechanism 6. The Artemisia argyi seeds and fertilizer are in the same longitudinal plane in the ditch, and the distribution of seeds and fertilizer is uniform. The engine 68 of the transmission mechanism 4 is located in the chassis of the support mechanism 1, and is transmitted through the transmission mechanism 4. The bevel gear 60 and shafts inside the drive mechanism 4 output a portion of the power to the second Artemisia argyi seed adsorption plate 43 and the first fertilizer adsorption plate 53, which mesh with the adjustable seed fertilizer adsorption device 2, thereby driving the Artemisia argyi seeds and fertilizer to move. Simultaneously, another portion of the power from the transmission mechanism 4 is transmitted to the wheel axle, realizing the overall movement of the machine. The negative pressure port of the air pressure supply mechanism 5 is connected to the air pressure hole located at the center of the adjustable seed fertilizer adsorption device 2 via a pipe and the internal air pressure transmission mechanism, thus controlling the negative pressure inside the adjustable seed fertilizer adsorption device 2. Meanwhile, due to… The adjustable seed-fertilizer adsorption device 2 has a small internal negative pressure chamber, resulting in a smaller negative pressure required for the blower 71 to form a near-vacuum, thus requiring less power from the blower 71. Simultaneously, the adjustable seed-fertilizer adsorption device 2 uses a flexible air ring adjustment device to adjust the number of working holes, thereby regulating the seeding rate. The positive pressure port of the air pressure supply mechanism 5 is connected to the seed and fertilizer delivery pipe at the front end of the seed-fertilizer movement path selection mechanism 3 via a pipeline, thereby accelerating the falling speed of the seed and fertilizer through the blowing action of positive pressure air. Adjustable trenching and covering mechanisms 6 on both the front and rear sides... Presenting a symmetrical design, the working parts such as the trencher, soil coverer, and individual leveling plate on the top are adjusted by the adjustment device on the adjustable trenching and soil covering mechanism 6 to select the working mode. That is, when moving forward, the soil coverer of the adjustable trenching and soil covering mechanism 6 at the rear is lifted, and at the same time, the trencher and each leveling plate together form a leveling support plate to perform soil leveling operation on the ground that has been covered with soil in front. Ultimately, the low-power fan 71 controls multiple rows of seed and fertilizer discharge, and the working mode is reciprocating operation, realizing the integrated operation of trenching, soil covering, and soil leveling, achieving the purpose of cost reduction and efficiency improvement.
[0047] Figures 1-12After the machine is started, the blower 71 generates negative pressure, which is transmitted to the negative pressure chamber 27 through components such as the negative pressure pipe 78. Under the action of negative pressure, the seed fertilizer carrying plate 31 adsorbs Artemisia argyi seed fertilizer. The left seed adsorption plate 42, the second Artemisia argyi seed adsorption plate 43, and the second fertilizer adsorption plate 44 also adsorb seed fertilizer simultaneously. The engine 68 drives the second seed plate gear support shaft 26 to rotate through the transmission mechanism 4. The adsorption plates meshing with the gear on the shaft rotate accordingly, transporting the adsorbed seed fertilizer. During the transportation process, the effective volume of the negative pressure chamber 27 is changed by adjusting the effective volume adjusting bolt 33 of the air chamber, thereby precisely controlling the amount of seed fertilizer adsorbed and transported, and realizing precise adjustment of the sowing amount. When the adsorption plate rotates to the adsorption and transportation start end of the seed fertilizer internal discharge port 46, the seed fertilizer is discharged through the Artemisia argyi seed fertilizer external discharge channel 45 and enters the subsequent seed fertilizer movement path selection mechanism 3.
[0048] Figures 1-12 When the seed fertilizer movement path selection mechanism 3 shown is in operation, it connects the first feeding channel 48 with the Artemisia seed fertilizer discharge channel 45 to ensure a tight connection and prevent seed fertilizer leakage. Connect the second feeding channel 49 onto the first feeding channel 48, ensuring a smooth connection without jamming. Install the circular hole in the middle of the seed fertilizer movement path selector 50 coaxially with the circular shaft at the center of the seed fertilizer movement path selection mechanism 3, ensuring a tight fit. The seed fertilizer movement path selector 50 should be able to rotate flexibly around the circular shaft. Connect the upper ends of the seed fertilizer rear conveying pipe 51 and the seed fertilizer front conveying pipe 52 to the front and rear ends of the second feeding channel 49, respectively. During debugging, rotate the seed fertilizer movement path selector 50 to check its flexibility. Observe the seed fertilizer entering the seed fertilizer rear conveying pipe 51 and the seed fertilizer front conveying pipe 52 through the first feeding channel 48 and the second feeding channel 49 at different rotation angles to ensure accurate path selection and smooth seed fertilizer delivery. Depending on the specific needs of the sowing operation, manually or through the control system, rotate the seed fertilizer movement path selector 50 to change its position. When the seed fertilizer movement path selector 50 rotates to a specific position, the seed fertilizer enters the corresponding seed fertilizer rear conveying pipe 51 or seed fertilizer front conveying pipe 52 from the first feeding channel 48 and the second feeding channel 49, so that the direction of seed fertilizer movement matches the direction of machine operation, realizing the function of adjusting the sowing direction according to different operation needs.
[0049] Figures 1-12During operation, the transmission mechanism 4 shown is used to fix the engine 68 in a designated position on the chassis, ensuring a secure and stable connection. The first vehicle body motion drive shaft 61 and the right front axle 62 are installed to transmit the power of the engine 68 to the front wheels, enabling them to rotate. The first transmission gear 63 and the second vehicle body motion drive shaft 65 are installed to transmit the vehicle body's power to the rear wheels, enabling the vehicle to move forward and backward. Three bevel gears 60 are installed and meshed together to drive the first and second middle transmission upstream drive shafts 59 and 64 to rotate. Middle transmission upstream gears 57 are installed on the first and second middle transmission upstream drive shafts 59 and 64, ensuring accurate installation and good meshing. The force is transmitted to the left and right middle transmission gears 55 via the transmission chain body 66, which then drive the first and second middle transmission upstream drive shafts 59 and 64 to rotate. The first fertilizer adsorption plate 53, the second Artemisia argyi seed adsorption plate 43, the left seed adsorption plate 42, and the second fertilizer adsorption plate 44 are respectively engaged with the corresponding central transmission gear 55 to ensure smooth gear transmission without jamming or abnormal noise. During debugging, the engine 68 is started, and the operation of each transmission component is observed. The tightness of gear meshing and the proper tension of the transmission chain body 66 are checked. Any abnormalities are adjusted promptly. The forward and backward movement of the vehicle body and the rotation of the seed fertilizer adsorption plate are tested to ensure accurate power transmission and synchronized movement of all components. After the engine 68 is started, the power is transmitted to the wheels sequentially through the first vehicle body movement transmission shaft 61, the right front axle 62, the first gear 63, and the second vehicle body movement transmission shaft 65 to achieve vehicle movement. At the same time, the power of the engine 68 drives the upstream transmission shaft 59 of the first middle transmission and the upstream transmission shaft 64 of the second middle transmission to rotate through the bevel gear 60. In turn, the transmission chain body 66 and the middle transmission gear 55 drive the seed fertilizer adsorption plate to rotate, so that the seed fertilizer adsorption plate can adsorb and transport the seed fertilizer, ensuring that the movement of the Artemisia argyi seeds and fertilizer is synchronized, and achieving efficient sowing operations.
[0050] Figures 1-12When using the air pressure supply mechanism 5 shown, fix the blower 71 to the corresponding position on the vehicle chassis, ensuring a secure fixation and stable operation. Connect the pipe to the negative pressure port of the blower 71, and install the first negative pressure tee pipe 72 and the negative pressure bend pipe 73 in sequence. Connect the upper ends of the first negative pressure tee pipe 72 and the negative pressure bend pipe 73 to the second negative pressure transmitter 74 and the first negative pressure transmitter 69, respectively. Finally, connect them to the second negative pressure port 77 through a hose to form a complete negative pressure transmission channel. Connect the positive pressure pipe and the positive pressure bend pipe to the positive pressure port of the blower 71, and connect them to the second positive pressure transmitter 75 and the positive pressure blowing pipe 76. Connect the positive pressure blowing pipe 76 to the rear delivery pipe, ensuring a tight connection without leakage. During commissioning, start the blower 71 and check the air pressure of the negative and positive pressure systems. Use pressure gauges and other tools to check whether the pressure of each part meets the design requirements. Observe the situation of the seed fertilizer during negative pressure adsorption and positive pressure accelerated descent. If any abnormality occurs, adjust the pipeline connection or check the operating parameters of the blower 71 to ensure that the air pressure system can work normally and provide suitable airflow support for sowing. During operation, the blower 71 starts, generating negative and positive pressure. The negative pressure is transmitted to the negative pressure chamber 27 and other parts through the negative pressure transmission channel, enabling the adsorption devices such as the seed fertilizer carrying plate 31 to adsorb the Artemisia argyi seed fertilizer. The positive pressure is transmitted to the positive pressure blowing pipe 76 through the positive pressure pipeline, which accelerates the descent of the Artemisia argyi seeds and fertilizer passing through the rear conveying pipe, reducing the descent time and improving sowing efficiency. During operation, the speed of the blower 71 can be adjusted through the control system according to the actual sowing situation to precisely control the airflow and meet different sowing needs.
[0051] Working Principle: When using the Artemisia seed fertilizer evenly planter for Artemisia cultivation, the adjustable seed fertilizer adsorption device 2 is fixed to the upper rear of the entire device via the support mechanism 1. Two adjustable ditching and soil covering mechanisms 6 are fixed to the front and rear ends of the vehicle body. The air pressure supply mechanism 5 is connected to the adjustable seed fertilizer adsorption device to achieve adsorption of Artemisia seeds and fertilizer inside. The transmission mechanism 4 drives the adsorption plate through bevel gear 60, shaft, gear, and chain, thereby transporting the adsorbed Artemisia seeds and fertilizer. After being transported to the seed discharge port, the material is scraped off by a brush or scraper installed near the seed discharge port and sent along the seed discharge channel to the seed fertilizer movement path selection mechanism 3. The seed fertilizer movement path selector 5 is adjusted... The rotation of 0 allows for the selection of the movement path of the Artemisia argyi seeds and fertilizer, delivering the seeds and fertilizer to the front or rear pipeline. They move under gravity and are then delivered to the adjustable ditching and covering mechanism 6 at the front or rear according to the working direction. The front and rear ditching and covering main shafts are symmetrically fixed on the front and rear frames. The internal adjustment mechanism of the adjustable ditching and covering mechanism 6 allows for the selection of the front and rear ditching, covering, and leveling operations according to the vehicle's working direction. Ultimately, this achieves a method of uniformly directing Artemisia argyi seeds and fertilizer with a large seeding volume driven by low-power wind pressure and adjustable seeding volume, while avoiding circular turns of the vehicle. The reciprocating motion integrates ditching, seed and fertilizer application, covering, and leveling operations.
