Description

Technical Field

[0001] This invention provides a double-disturbance, soil-loosening, and root-cutting Cistanche deserticola planter, belonging to the field of agricultural mechanization equipment, and is mainly used for Cistanche deserticola sowing operations. Background Technology

[0002] Cistanche deserticola is a parasitic medicinal plant, often referred to as "desert ginseng." Its seeds can only germinate by attaching to the lateral roots of psammophytic shrubs such as Haloxylon ammodendron, Tamarix chinensis, and Trichoderma tetrapanax. Cistanche deserticola seeds are less than 1 mm in diameter, with a thousand-seed weight of only 0.09 g. According to agronomical requirements, they must be sown close to the root system at a depth of 400–600 mm below the host plant's root system. Due to the large sowing depth, the unique characteristics of the seeds, and the specific working conditions, the overall cultivation process is extremely demanding.

[0003] Currently, no specialized sowing equipment has been developed abroad for the deep parasitic sowing process of Cistanche deserticola. Existing medicinal herb sowing machines in Japan, South Korea, Europe, and the United States are only suitable for direct seeding in shallow farmland soil, with limited operating depth. They lack the capability for deep trench sowing in deserts and cannot meet the specific agronomic requirements for Cistanche deserticola sowing. Domestically available Cistanche deserticola sowing equipment mainly includes four types: manual drilling and grouting sowing devices, air-blown stratified furrow seeders, integrated liquid spraying machines, and chain-type furrowing and sowing machines. Each type of equipment has inherent technical defects and poor adaptability. Among these, manual drilling and grouting seeding devices rely on manual single-point operation, resulting in high labor intensity and low efficiency, making them unsuitable for large-scale planting. Air-blown stratified furrow seeders use airflow for seed dispersal, but small, lightweight seeds are prone to drifting and loss, leading to poor seeding uniformity. Liquid spray seeding machines suffer from problems such as leakage at the mixing point, seed solution stratification and sedimentation, and a narrow seed attachment area on the furrow walls, limiting the effective seeding range. Chain-type furrowing seeding machines have excessively wide furrows, easily scratching and tearing the host's main root system during operation, leading to a reduced survival rate of Cistanche deserticola seeds. Furthermore, existing seeding equipment uses a single linear seeding structure at the bottom of the furrow, failing to achieve full-area root-attachment seeding in the furrow, resulting in insufficient compatibility with the agronomical characteristics of Cistanche deserticola's parasitic germination and an overall low seeding survival rate. Additionally, small seeds are highly susceptible to clogging, strip breakage, and unstable seeding accuracy during operation, resulting in poor operational reliability. Manual and semi-mechanized planting methods involve high labor input and costs. Existing integrated equipment lacks sufficient synchronization in the trenching, sowing, and covering processes, resulting in poor soil moisture retention under loose desert sand conditions. Large-scale planting also leads to persistently high labor costs. Due to multiple constraints, including seed physical characteristics, deep sowing techniques, and the complex working environment of sandy areas, there is currently no mature, commercially viable sowing equipment specifically designed for Cistanche deserticola that can be widely industrialized.

[0004] In summary, existing technologies cannot simultaneously meet the core operational requirements of uniform seeding across the entire trench area, minimal damage to the host root system, and precision seeding without clogging. There is an urgent need for a dedicated seeding equipment for Cistanche deserticola that is suitable for deep seeding conditions of 400-600mm in desert, can achieve uniform seeding across the entire trench area, minimizes damage to the host root system, and can effectively prevent seeding errors such as missed seeding and clogging. Summary of the Invention

[0005] The purpose of this invention is to provide a double-disturbance, soil-loosening, root-cutting Cistanche deserticola planter that can overcome the problems existing in the current agricultural mechanization equipment industry. It can not only sow seeds evenly in three dimensions along the entire depth and width of the trench below 400mm, but also accurately cut the roots of the parasitic plants, with high sowing efficiency and good operational reliability.

[0006] The technical solution includes a frame, a suspension frame, a soil loosening device, and a seeding device. The frame is attached to the tractor's suspension system via the suspension frame. The soil loosening device and the seeding device are mounted on the frame, and the soil loosening device is connected to the tractor's power take-off shaft via a drive shaft. When the tractor drives the seeder forward, the seeding device sows the Cistanche deserticola seeds in the loose soil trough formed after the soil loosening device has loosened the soil.

[0007] The aforementioned double-disturbance, soil-loosening, root-cutting Cistanche deserticola planter has a frame including a crossbeam, a transmission seat plate, a soil-loosening frame, and an adjusting cylinder. The crossbeam is composed of two steel pipes that are parallel to each other and aligned at both ends. A transmission seat plate is fixed to the middle of one of the steel pipes of the crossbeam on the side away from the other steel pipe, and the surface of the transmission seat plate is parallel to the plane containing the two steel pipes of the crossbeam. A suspension frame is fixed to the edge of the transmission seat plate on the side away from the crossbeam. The soil loosening frame includes uprights, columns, telescopic rods, soil-dispersing arrows, a taproot cutter, a seeding frame, a guide plate, and a protective plate. Two uprights are fixed at one end to one end of a column, forming an L-shape. Two telescopic rods are fixed at one end to the outside of one upright, parallel to each other, perpendicular to the surface of the uprights, and perpendicular to the length of the column. The soil-dispersing arrow is mounted on the column. A taproot cutter is slidably mounted on the end of the column furthest from the uprights. The taproot cutter extends outwards towards the side furthest from the telescopic rods, and its position relative to the length of the column is adjustable. This cutter cuts the taproots of the plants parasitized by *Cistanche deserticola*, such as *Haloxylon ammodendron*, *Tamarix chinensis*, and *Trifolium repens*, promoting lateral root growth. The cutter can be adjusted according to the growth age of the plants parasitized by *Cistanche deserticola*. The root cutting depth of the main root cutter is adjustable; a seeding frame is fixed at the L-shaped corner formed by the upright plate and the column. A guide plate is installed on the side of the seeding frame near the main root cutter. A protective plate is installed on the edge of the two upright plates away from the main root cutter to prevent the chopped and raised soil fragments from flying everywhere and to return to the cut trench to fill the trench; two loosening frames are symmetrically and slidably inserted into the two steel pipes of the crossbeam from both ends of the crossbeam through two telescopic rods. One adjusting cylinder is hinged to one end of one steel pipe of the crossbeam, and the other adjusting cylinder is hinged to the other end of the other steel pipe of the crossbeam. The telescopic rods of the two adjusting cylinders are respectively hinged to the telescopic rods of the two loosening frames near the upright plate to adjust the distance between the two loosening frames.

[0008] The soil-loosening frame of the aforementioned dual-disturbance, root-cutting Cistanche deserticola planter includes a soil-dispersing arrow comprising a soil-dispersing blade I, a soil-dispersing blade II, mounting ears, a lateral root cutter, and a diverting blade. Both soil-dispersing blade I and soil-dispersing blade II are right-angled triangular flat plates. One right-angled side of each blade extends vertically outward to a mounting ear, thus forming an "arrowhead" shape with the intersection of the other right-angled side and the hypotenuse as its vertex. Two soil-dispersing blades I are symmetrically fixed to the two sides of the right-angled triangular flat plate of the lateral root cutter via their right-angled sides not extending outward from the mounting ears. The surfaces of the two soil-dispersing blades I are perpendicular to the surface of the lateral root cutter, and the surfaces of the two soil-dispersing blades I and one right-angled side of the lateral root cutter are located in the same plane. The right-angled sides of the two soil-dispersing blades I with the mounting ears extending outward from the lateral root cutter are also perpendicular to the surface of the lateral root cutter. The other right-angled side of the root cutter lies in the same plane, and the two mounting ears extend away from the side root cutter; therefore, the angle formed by the right-angled side and the hypotenuse of the side root cutter and the surface of the soil disturbing blade I, which lie in the same plane, points in the same direction as the "arrow" of the two soil disturbing blades I; the two soil disturbing blades II are symmetrically fixed to the two side plates of the side root cutter by the right-angled sides that do not extend out of the mounting ears, and the surfaces of the two soil disturbing blades II are parallel to the surfaces of the two soil disturbing blades I. The right-angled sides of the two soil disturbing blades II with the mounting ears extending out lie in the same plane as the other right-angled side of the side root cutter, and the extension direction of the mounting ears of the soil disturbing blades II is the same as the extension direction of the mounting ears of the soil disturbing blades I; therefore, the "arrow" of the two soil disturbing blades II points in the same direction as the "arrow" of the two soil disturbing blades I, thus the "arrow" of the two soil disturbing blades I... Two soil-disrupting blades II, forming an "arrowhead," and the angles of the right-angled side and hypotenuse of the side root cutter together constitute a "three-dimensional arrowhead." The diverting blade is a right-angled triangular prism. Two diverting blades are symmetrically fixed to the two side plates of the side root cutter via a triangular prism plane formed by one right-angled side. The two diverting blades are located between soil-disrupting blades I and II on the same side plate of the side root cutter. Furthermore, the triangular prism plane formed by the other right-angled side of the two diverting blades is in the same plane as the right-angled side of soil-disrupting blade I with its mounting lug. The soil-disrupting arrow passes through soil-disrupting blade I and the diverting blade... The mounting lugs of the soil-distributing blade II and the triangular prism plane of the diverting blade are installed on the side of the column closest to the upright plate, with the "three-dimensional arrow" pointing away from the column. The surface of the soil-dispersing blade I is perpendicular to the length direction of the column, and the surface of the lateral root cutting blade is parallel to the length direction of the column. Therefore, during operation, the lateral root cutting blade can effectively cut the lateral roots of the parasitic plant to stimulate the growth of more lateral roots. The soil-dispersing blade I can cut and disturb the soil on both sides to increase the width of the trench, while the diverting blade can divert the soil in front of the column to both sides to avoid soil congestion in front of the column.

[0009] The aforementioned dual-disturbance, soil-loosening, root-cutting Cistanche deserticola planter includes a soil-loosening device comprising a transmission box, soil-loosening components, and universal joints. The transmission box is mounted on the transmission base plate of the machine frame, and its input shaft is connected to the power output shaft of the tractor via a transmission shaft. Two soil-loosening components are respectively supported on the vertical plates of the soil-loosening frame of the machine frame. One end of the two universal joints, whose length can be automatically extended and retracted, is connected to two output shafts on both sides of the transmission box, and the other end is connected to the input shafts of the two soil-loosening components supported on the vertical plates. During the sowing process, the axes of the two soil-loosening components are allowed to fluctuate within a certain range relative to the output shaft axis of the transmission box. Since the length of the universal joints can be automatically extended and retracted, they can also automatically adapt to the adjustment of the sowing row spacing.

[0010] The soil loosening device of the double-interference soil loosening and root cutting type Cistanche deserticola sowing machine according to claim , wherein the soil loosening assembly comprises a chain drive and a double rocker mechanism, the chain drive is supported between two vertical plates of a soil loosening frame of a frame, and the driving end of the chain drive is connected with one end of a universal shaft; the double rocker mechanism comprises a crank, a first rocker mechanism, a second rocker mechanism and a limiting rod, wherein a straight shaft section at the middle part of the crank is supported between two vertical plates of the soil loosening frame and connected with a driven end of the chain drive; the axes of the output shaft journals of the two ends of the crank after passing through the vertical plates are not coaxial with the axis of the middle straight shaft section, the offset distances relative to the axis of the straight shaft section are equal, and the offset directions relative to the axis of the straight shaft section are opposite, so that a 180° phase difference is formed; a first rocker of the first rocker mechanism is herringbone-shaped, both the left stroke and right stroke of the herringbone shape are arc-shaped, the arcs bend in the same direction, and cutting edges are formed after chamfering the concave surfaces; two first rockers are sleeved on both sides of the driving end of the chain drive of the soil loosening assembly through the top ends of the herringbone shapes, and the concave edge of the first rocker faces away from the vertical column of the soil loosening frame of the frame; one end of two first connecting rods of the first rocker mechanism is respectively hinged between the left stroke and the right stroke of the herringbone shape of the two first rockers, and the other end is respectively hinged on the axis offset section journals at the two ends of the crank of the double rocker mechanism; therefore, the crank can respectively drive the two first rockers to swing around the driving end of the chain drive through the two first connecting rods, and the swing cycles differ by a phase angle of 180°; due to alternate disturbance of the two first rockers, the soil can be loosened, which is beneficial for sowing Cistanche deserticola; a second connecting rod of the second rocker mechanism is arc-shaped, and a cutting edge is formed after chamfering the concave surface, one end of two second connecting rods of the second rocker mechanism is respectively hinged on the axis offset section journals at the two ends of the crank of the double rocker mechanism, and the concave edge of the second connecting rod faces away from the vertical column of the soil loosening frame of the frame; one end of two second rockers of the second rocker mechanism is respectively hinged to the middle parts of the two second connecting rods, and the other ends of the two second rockers are respectively hinged to the vertical column of the soil loosening frame; therefore, the crank can respectively drive the two second connecting rods to perform plane motion, and the plane motion cycles of the two second connecting rods differ by a phase angle of 180°; due to alternate disturbance of the two second connecting rods, the soil can be further loosened, which is more beneficial for sowing Cistanche deserticola; two ends of the elastic limiting rod are respectively connected with the two second connecting rods of the second rocker mechanism, so that the distance between the two second connecting rods of the second rocker mechanism can be effectively limited, which can not only ensure the normal plane motion of the two second connecting rods, but also effectively avoid left and right shaking of the second connecting rods caused by changes in the hardness of the soil on both sides of the second connecting rods.

[0011] The aforementioned dual-disturbance, soil-loosening, root-cutting Cistanche deserticola seeder includes a seeder, a seeder shaft, a seeder drive, a support, and a seed guide tube. The seeder uses a honeycomb wheel design. The seeder shaft, passing through multiple seeder units, has a seeder drive and support at both ends. The seeding rate can be set per acre, and an intelligent control system precisely controls the seeder drive speed for precision seeding. The inlet of the seed guide tube is parallel to the axis of the inlet section, while the outlet of the seed guide tube is perpendicular to the axis of the outlet section. The inlet and outlet axes of the seed guide tube are parallel. For seed guide tubes with the same number of units as the seeder, the distances between the inlet and outlet axes are unequal, and the distances between the inlet and outlet axes are also unequal along the direction of the inlet axis of the seed guide tube. The outlet end of the seed guide tube has an outlet tongue to ensure the Cistanche deserticola is properly positioned. Seeds are evenly discharged along the entire seed discharge end of the seed guide tube; each seed inlet of the seed guide tube is connected to the seed outlet of each seeder, and the direction of each seed discharge end of the seed guide tube is parallel to the axis of the seeding shaft; the seeders of the two seeding devices are respectively installed on the seeding frames of the two loosening frames of the machine frame, and the seed outlet of each seeder faces the end of the column of the loosening frame away from the upright plate. The axis of each seed inlet section of the seed guide tube is parallel to the length direction of the column, and the seed guide tube extends towards the main root cutter. The seeding drive and support of the two seeding devices are also supported on the seeding frame; each seed inlet section of the seed guide tube of the two seeding devices is supported on the guide plate of the two loosening frames of the machine frame. The direction of each seed discharge end of the seed guide tube is parallel to the "arrow" of the soil disturbing blade of the soil disturbing arrow of the loosening frame of the machine frame, and opposite to the direction of the "arrow" of the soil disturbing blade. During operation, the seeder can evenly distribute Cistanche deserticola seeds into each seed guide tube. Then, the seeds are discharged through the openings at each seed discharge end of the seed guide tube into the loose soil trough formed by the soil loosening component of the soil loosening device. The seed discharge depth and lateral position are also different, thus achieving staggered seeding.

[0012] The innovative aspects of this invention compared to existing technologies in the field are as follows: (1) To address the pain points that restrict the cultivation of Cistanche deserticola, such as the difficulty of full-area root-attachment inoculation on the trench wall, poor adaptability, and low inoculation survival rate, as well as the prominent problems of easy seed blockage, strip breakage, and even loss of sowing accuracy, high labor intensity, and high cost, a technical solution is adopted, which includes a soil loosening device to break the soil into a loose soil trench, a soil disturbing arrow to cut and disturb the soil on both sides and the lateral roots of the parasitic plant, a diverting knife to divert the soil, a main root cutter to cut the main root of the parasitic plant, and staggered sowing by the sowing device. The soil, which becomes loose after being broken by the double rocker mechanism, is then diverted by the diverting knife and then fully mixed with the seeds sown by the sowing device, the roots of the Cistanche deserticola parasitic plant cut by the main root cutter, and the soil chopped by the main root cutter. This improves the inoculation rate, helps to retain moisture, ensures successful inoculation and rapid germination of seeds, provides sufficient growth space for Cistanche deserticola, and effectively improves yield and economic benefits. (2) Because it is equipped with a soil loosening device, it can break up the soil to form a 600mm loose soil trough, which lays the foundation for the subsequent sowing of Cistanche deserticola. (3) Since the "arrowhead" of the soil disturbing blade I, the "arrowhead" of the soil disturbing blade II, and the angle of the right-angled side and the hypotenuse of the lateral root cutter form a "three-dimensional arrowhead", when the soil disturbing arrow runs in the direction pointed by the "three-dimensional arrowhead", each soil disturbing blade I and soil disturbing blade II can cut and disturb the soil on both sides. This can not only loosen the soil, but also prevent the soil from being squeezed to both sides. It can also increase the width of the loose soil groove formed by the soil loosening device. Under the premise of ensuring that the horizontal sowing area of ​​the seeds remains unchanged, the loosening width of the soil loosening device can be effectively reduced to minimize energy consumption. At the same time, the lateral root cutter can also effectively cut off the lateral roots of the parasitic plant to stimulate the growth of more lateral roots and improve the inoculation success rate of Cistanche deserticola. (4) Because the diversion blade of the soil-disrupting arrow is in the shape of a right triangle and is symmetrically installed on both sides of the lateral root cutter, it can divert the soil in front of the column to both sides during operation, so as to avoid soil congestion in front of the column and reduce the forward resistance of the seeder. (5) Since the end of the column is equipped with a main root cutter that extends to one side and the position of the main root cutter is adjustable, the main roots of plants such as Haloxylon ammodendron, Tamarix chinensis or Tripterygium wilfordii that are parasitized by Cistanche deserticola can be cut off, promoting the growth of lateral roots. The cutting depth of the main root cutter can also be adjusted according to the growth years of the plants parasitized by Cistanche deserticola. (6) The soil, which has become loose after being shredded by the double rocker mechanism, is then diverted by the diverting blade and bypasses the column. It is then thoroughly mixed with the seeds sown by the seeder of the sowing device, the roots of the plant parasitizing Cistanche deserticola cut by the main root cutter, and the soil shredded by the main root cutter. In addition, the soil above the trench collapses, which helps to retain moisture and ensures successful seed inoculation and rapid germination. (7) When the soil disturbing blades I and II of the soil disturbing arrow are moving forward in the soil, if the sowing depth of the seeder fluctuates due to uneven soil or changes in soil hardness, causing the surfaces of soil disturbing blades I and II to tilt, the impact force and friction generated by the soil on the surfaces of soil disturbing blades I and II will push soil disturbing blades I and II to swing in the opposite direction, thereby forcing soil disturbing blades I and II to automatically return to a horizontal state. Therefore, it can ensure that the seeder always operates stably at the set sowing depth. (8) Because the elastic limiting rod is used to limit the distance between the two connecting rods II of the rocker mechanism II, it can ensure that the two connecting rods II can move normally in the plane, and can effectively avoid the left and right swaying of the connecting rods II due to the change in the hardness of the soil on both sides of the connecting rods II. This ensures the smooth implementation of the rocker mechanism II's soil disturbance operation and ensures the stability and reliability of the seeder. (9) Because the distance between the axis of each seed inlet section and the axis of each seed outlet section of the seed guide tube of the seeding device is not equal, and the distance between the axis of each seed inlet section and the axis of each seed outlet section in the direction of the axis of the seed inlet section of the seed guide tube is also not equal, the seeds of Cistanche deserticola that are discharged into each seed guide tube are discharged into the loose soil trough formed by the soil breaking up by the soil loosening component of the soil loosening device through the pipe openings of each seed outlet end of the seed guide tube. Their seeding depth and lateral position are also different, thereby achieving staggered sowing. Under the premise of ensuring the success rate of inoculation, the amount of expensive Cistanche deserticola seeds used can be effectively reduced. (10) Because the seed outlet of the seed delivery tube is equipped with a seed outlet tongue, it ensures that the seeds of Cistanche deserticola are evenly discharged along the entire seed outlet of the seed delivery tube, thus increasing the seed sowing range and further reducing the amount of seeds used. 11. Since the adjustment cylinder of the frame is connected to the hydraulic system of the tractor through the oil pipe, it can not only conveniently and accurately adjust the sowing row spacing, but also adjust the telescopic rod of the loosening frame to the deepest part of the crossbeam steel pipe after sowing, so as to minimize the lateral width of the implement and improve the transportability of the seeder. 12. Due to the adoption of a honeycomb wheel seeder and intelligent control system, the driver can set the seeding rate per acre in the cab and can accurately and automatically control the seeding drive speed, thus achieving precision seeding; 13. Because the transmission box of the soil loosening device uses a universal joint to drive the soil loosening components on both sides, the input shaft axis of the soil loosening components is allowed to fluctuate within a certain range relative to the output shaft axis of the transmission box during operation, thus ensuring safe and reliable operation. 14. Because the length of the universal joint can be automatically extended or retracted, it can automatically adapt to the adjustment of the sowing row spacing. Attached Figure Description

[0015] exist Figures 1-10 In the illustrated embodiment: the frame 1 is attached to the tractor's suspension system via the suspension bracket 2. The soil loosening device 3 and the seeding device 4 are mounted on the frame 1, and the soil loosening device 3 is connected to the tractor's power take-off shaft via a drive shaft. When the tractor drives the seeder forward, the seeding device 4 sows the Cistanche deserticola seeds into the loose soil trough formed by the soil loosening component 32 of the soil loosening device 3.

[0016] exist Figures 1-3 In the embodiment shown: the crossbeam 11 of the frame 1 is composed of two steel pipes, which are parallel to each other and aligned at both ends. A transmission seat plate 12 is fixed to the middle of one of the steel pipes of the crossbeam 11 away from the other steel pipe, and the surface of the transmission seat plate 12 is parallel to the plane of the two steel pipes of the crossbeam 11. A suspension bracket 2 is fixed to the edge of the transmission seat plate 12 away from the crossbeam 11 so as to be attached to the tractor.

[0017] exist Figures 1-4In the embodiment shown: two upright plates 131 of the soil loosening frame 13 are fixed at one end to one end of the column 132, and the upright plates 131 and the column 132 form an L-shape. Two telescopic rods 133 are fixed at one end to the outside of one upright plate 131. The two telescopic rods 133 are parallel to each other, perpendicular to the surface of the upright plate 131, and perpendicular to the length direction of the column 132. Soil-disturbing arrows 134 are installed on the column 132, and a main root is slidably mounted on the end of the column 132 away from the upright plate 131. The cutting blade 135 extends outward from the side away from the telescopic rod 133, and its position relative to the length of the column 132 is adjustable. This cuts the main roots of the plants parasitized by *Cistanche deserticola*, such as *Haloxylon ammodendron*, *Tamarix chinensis*, and *Trifolium repens*, promoting lateral root growth and increasing the survival rate of *Cistanche deserticola*. Furthermore, the cutting depth of the main root cutting blade 135 can be adjusted according to the growth age of the parasitized plants to prevent death due to inappropriate cutting depth. A sowing frame 136 is fixed at the L-shaped corner formed by the upright plate 131 and the column 132. A guide plate 137 is installed on the side of the sowing frame 136 closest to the main root cutting blade 135. A protective plate 138 is installed on the edge of the two upright plates 131 away from the main root cutting blade 135 to prevent shredded and scattered soil fragments, which are then returned to the cut trench to fill it, facilitating subsequent sowing. Two symmetrically shaped soil loosening frames 13 are symmetrically and slidably inserted into two steel pipes of the crossbeam 11 from both ends via two telescopic rods 133. One adjusting cylinder 14 is hinged to one end of one steel pipe of the crossbeam 11, and the other adjusting cylinder 14 is hinged to the other end of the other steel pipe of the crossbeam 11. The telescopic rods of the two adjusting cylinders 14 are respectively hinged to the telescopic rods 133 of the two soil loosening frames 13 near the upright plate 131. Therefore, the distance between the two soil loosening frames 13 can be adjusted by extending and retracting the telescopic rods of the two adjusting cylinders 14, thereby adjusting the sowing row spacing.

[0018] exist Figures 1-5In the embodiment shown: the soil disturbing blades I 1341 and II 1342 of the soil disturbing arrow 134 are both in the shape of right-angled triangular flat plates. One right-angled side of both soil disturbing blades I 1341 and II 1342 extends vertically outward with mounting ears 1343. Thus, soil disturbing blade I 1341 and mounting ears 1343, and soil disturbing blade II 1342 and mounting ears 1343, all form an "arrow" shape with the intersection of the other right-angled side and the hypotenuse as the vertex. The lateral root cutter 1344 is a right-angled triangular plate. Two soil disturbing blades I 1341 are symmetrically fixed to the two side plates of the lateral root cutter 1344 via their right-angled sides that do not extend beyond the mounting ears 1343, and the plates of the two soil disturbing blades I 1341 are perpendicular to the plate of the lateral root cutter 1344. The plates of the two soil disturbing blades I 1341 and one right-angled side of the lateral root cutter 1344 are in the same plane, and the right-angled side of the two soil disturbing blades I 1341 with the mounting ears 1343 extends into the same plane as the other right-angled side of the lateral root cutter 1344, with the mounting ears 1343 extending away from the lateral root cutter 1344. Therefore, the angle formed by the right-angled side and the hypotenuse of the plates of the lateral root cutter 1344 and the soil disturbing blades I 1341 in the same plane points in the same direction as the "arrow" of the two soil disturbing blades I 1341. Two soil-disrupting blades II 1342 are symmetrically fixed to the two side plates of the side root cutter 1344 via their right-angled sides without protruding mounting ears 1343. The plates of the two soil-disrupting blades II 1342 are parallel to the plates of the two soil-disrupting blades I 1341. The right-angled sides of the two soil-disrupting blades II 1342 with protruding mounting ears 1343 are in the same plane as the other right-angled side of the side root cutter 1344, and the protrusion direction of the mounting ears 1343 of the soil-disrupting blades II 1342 is the same as that of the mounting ears 1343 of the soil-disrupting blades I 1341. Therefore, the "arrows" of the two soil-disrupting blades II 1342 point in the same direction as the "arrows" of the two soil-disrupting blades I 1341. Thus, the "arrows" of the two soil-disrupting blades I 1341, the "arrows" of the two soil-disrupting blades II 1342, and the angles of the right-angled side and the hypotenuse of the side root cutter 1344 constitute a "three-dimensional arrow." The diverting blade 1345 is in the shape of a right-angled triangular prism. Two diverting blades 1345 are symmetrically fixed on the two side plates of the side root cutter 1344 through a triangular prism plane formed by one right-angled side. The two diverting blades 1345 are respectively located between the soil disturbing blade I 1341 and the soil disturbing blade II 1342 on the same side plate of the side root cutter 1344. The triangular prism plane formed by the other right-angled side of the two diverting blades 1345 and the right-angled side of the soil disturbing blade I 1341 with the mounting lug 1343 are in the same plane. The soil-disrupting arrow 134 is mounted on the side of the column 132 near the upright plate 131 via the mounting ears 1343 extending from the soil-disrupting blade I 1341 and the soil-disrupting blade II 1342, and the triangular prism plane of the diverting blade 1345. The "three-dimensional arrow" points away from the column 132. The surface of the soil-disrupting blade I 1341 is perpendicular to the length direction of the column 132, and the surface of the side root cutter 1344 is parallel to the length direction of the column 132.Therefore, during operation, the lateral root cutter 1344 can effectively cut the lateral roots of the parasitic plant to stimulate the growth of more lateral roots. The soil disturbing blades I 1341 and II 1342 can cut and disturb the soil on both sides, thereby loosening the soil and increasing the width of the loose soil groove formed by the soil loosening component 32. While ensuring that the lateral sowing area of ​​the seeds remains unchanged, the cutting width of the soil loosening component 32 can be reduced to minimize energy consumption. The diverting blade 1345 can divert the soil in front of the column 132 to both sides to avoid soil congestion in front of the column 132, thereby reducing the forward resistance of the seeder. After the soil diverted by the diverting blade 1342 bypasses the column 132, it is fully mixed with the seeds sown by the seeder 41 of the sowing device 4, the roots of the plant parasitized by Cistanche deserticola cut by the main root cutter 135, and the soil chopped by the main root cutter 135. Therefore, it is beneficial to retain moisture and ensure successful seed inoculation and rapid germination. In addition, when the soil disturber 134 moves forward in the soil, if the sowing depth of the seeder fluctuates due to uneven soil or changes in soil hardness, causing the surfaces of the soil disturber blades I 1341 and II 1342 to tilt in either a "lower front and higher back" or "higher front and lower back" manner, the impact force and friction generated by the soil on the surfaces of the soil disturber blades I 1341 and II 1342 will push the soil disturber blades I 1341 and II 1342 to swing in the opposite direction. This forces the soil disturber blades I 1341 and II 1342, and consequently the entire soil disturber 134, to automatically return to a horizontal position. Therefore, it can ensure that the seeder always operates stably at the set sowing depth.

[0019] exist Figure 1 , Figure 2 and Figure 6 In the illustrated embodiment: the transmission box 31 of the soil loosening device 3 is mounted on the transmission base plate 12 of the frame 1, and the input shaft of the transmission box 31 is connected to the power output shaft of the tractor via a transmission shaft. Two soil loosening components 32 are respectively supported on the upright plate 131 of the soil loosening frame 13 of the frame 1. Two universal joints 33, whose length can be automatically extended and retracted, are connected at one end to two output shafts on both sides of the transmission box 31, and at the other end to the input shafts of the two soil loosening components 32 supported on the upright plate 131. Therefore, the tractor can drive the two soil loosening components 32 on both sides to operate through the transmission box 31 and the two universal joints 33, and allow the axis of the input shaft of the two soil loosening components 32 to fluctuate within a certain range relative to the axis of the output shaft of the transmission box 31. Since the length of the universal joints 33 can be automatically extended and retracted, it can automatically adapt to the adjustment of the sowing row spacing.

[0020] exist Figure 1 , Figure 2 and Figures 6-8In the embodiment shown: the chain drive 321 of the soil loosening assembly 32 is supported between the two vertical plates 131 of the soil loosening frame 13 of the frame 1, and the driving end of the chain drive 321 is connected to one end of the universal shaft 33. The straight shaft section at the middle part of the crank 3221 of the double rocker mechanism 322 is supported between the two vertical plates 131 of the soil loosening frame 13, and is connected to the driven end of the chain drive 321; the axes of the journals at the extending ends of the crank 3221 after passing through the vertical plates 131 are not coaxial with the axis of the middle straight shaft section, the offset distances relative to the axis of the straight shaft section are equal, and the offset directions relative to the axis of the straight shaft section are opposite, thereby forming a phase difference of 180°. The first rocker of the first rocker mechanism 3222 is herringbone-shaped, both the "left-falling stroke" and "right-pressing stroke" of the herringbone shape are arc-shaped, the arcs bend in the same direction, and cutting edges are formed after chamfering the concave surfaces; the two first rockers are idly sleeved on both sides of the driving end of the chain drive 321 of the soil loosening assembly 32 through the top ends of the herringbone shape, and the concave cutting edges of the first rockers face away from the direction of the vertical column 132 of the soil loosening frame 13 of the frame 1; one ends of the two first connecting rods of the first rocker mechanism 3222 are respectively hinged between the "left-falling stroke" and "right-pressing stroke" of the herringbone shape of the two first rockers, and the other ends are respectively hinged on the axis offset section journals at both ends of the crank 3221 of the double rocker mechanism 322. Therefore, the crank 3221 can respectively drive the two first rockers to swing around the driving end of the chain drive 321 through the two first connecting rods, and the swing periods differ by a phase angle of 180°, which can effectively avoid the jumping of the frame 1 caused by the swinging of the first rocker mechanism 3222, which would otherwise affect the stability and operation reliability of the seeder; the alternating disturbance of the two first rockers can loosen the soil, which is conducive to the sowing of Cistanche deserticola. The second connecting rod of the second rocker mechanism 3223 is arc-shaped, and a cutting edge is formed after chamfering the concave surface; one ends of the two second connecting rods of the second rocker mechanism 3223 are respectively hinged on the axis offset section journals at both ends of the crank 3221 of the double rocker mechanism 322, and the concave cutting edges of the second connecting rods face away from the direction of the vertical column 132 of the soil loosening frame 13 of the frame 1; one ends of the two second rockers of the second rocker mechanism 3223 are respectively hinged to the middle parts of the two second connecting rods, and the other ends of the two second rockers are respectively hinged to the vertical column 132 of the soil loosening frame 13. Therefore, the crank 3221 can respectively drive the two second connecting rods to perform planar motion, and the planar motion periods of the two second connecting rods differ by a phase angle of 180°, which can effectively avoid the jumping of the frame 1 caused by the planar motion of the second rocker mechanism 3223, which would otherwise affect the stability and operation reliability of the seeder; the alternating disturbance of the two second connecting rods can further loosen the soil, which is more conducive to the sowing of Cistanche deserticola.The elastic limiting rod 3224 is connected at both ends to the two connecting rods II of the rocker mechanism II 3223, thereby effectively limiting the distance between the two connecting rods II. This ensures that the two connecting rods II can move normally in a plane, while effectively preventing the connecting rods II from swaying left and right due to changes in the hardness of the soil on both sides. This ensures the smooth implementation of the soil disturbance operation by the rocker mechanism II 3223 and ensures the stable and reliable operation of the seeder. Thus, driven by the tractor's power take-off shaft through the transmission box 31 and the universal joint 33, the double rocker mechanism 322 can break up the soil to form a loose soil trough, laying the foundation for the successful sowing of Cistanche deserticola.

[0021] exist Figure 1 , Figure 2 , Figure 9 and Figure 10In the illustrated embodiment: the sowing device 4 adopts a honeycomb wheel type, with a sowing drive 43 and a support 44 respectively installed at both ends of the sowing shaft 42 passing through the four sowing devices 41. The sowing rate per acre can be set, and an intelligent control system is used to precisely control the rotation speed of the sowing drive 43 to achieve precision sowing. The direction of the inlet of the seed guide tube 45 is parallel to the axis of the inlet section of the seed guide tube 45, and the direction of the outlet of the seed guide tube 45 is perpendicular to the axis of the outlet section of the seed guide tube 45. The axis of the inlet section of the seed guide tube 45 is parallel to the axis of the outlet section. The four sowing devices 41... The distance between the axis of each seed inlet section and the axis of each seed outlet section of the seed tube 45 is not equal, and the distance between the axis of each seed inlet section and the axis of each seed outlet section in the direction of the axis of the seed inlet section of the seed tube 45 is also not equal; a seed outlet tongue 451 is provided in the seed outlet end of the seed tube 45 to ensure that the seeds of Cistanche deserticola are evenly discharged along the entire seed outlet end of the seed tube 45, thereby increasing the seed sowing range; each seed inlet end of the seed tube 45 is connected to the seed outlet of each seeder 41, and the direction of each seed outlet end of the seed tube 45 is parallel to the axis of the seeding shaft 42. The seeders 41 of the two seeding devices 4 are respectively installed on the seeding frames 136 of the two loosening frames 13 of the frame 1, and the seed outlet of each seeder 41 is facing the end of the column 132 of the loosening frame 13 away from the upright plate 131. The axis of each seed inlet section of the seed guide tube 45 is parallel to the length direction of the column 132, and the seed guide tube 45 extends towards the main root cutter 135. The seeding drive 43 and the support 44 of the two seeding devices 4 are also supported on the seeding frame 136. Each seed inlet section of the seed guide tube 45 of the two seeding devices 4 is supported on the guide plate 137 of the two loosening frames 13 of the frame 1. The direction of each seed outlet of the seed guide tube 45 is parallel to the direction of the "three-dimensional arrow" of the soil disturbing arrow 134 of the loosening frame 13 of the frame 1, and opposite to the direction of the "three-dimensional arrow". As the sowing device 4 moves forward with the tractor via the frame 1, the sowing drive 43 drives each sower 41 to rotate via the sowing shaft 42, evenly distributing the Cistanche deserticola seeds into each seed guide tube 45. Since the distance between the axis of each seed inlet section and the axis of each seed outlet section of the seed guide tube 45 is not equal, and the distance between the axis of each seed inlet section and the axis of each seed outlet section in the direction of the axis of the seed inlet section of the seed guide tube 45 is also not equal, the Cistanche deserticola seeds distributed into each seed guide tube 45 are discharged through the openings of each seed outlet end of the seed guide tube 45 into the loose soil trough formed by the soil loosening component 32 of the soil loosening device 3. Their seeding depth and lateral position are also different, thus achieving staggered sowing.

[0022] Its working principle is as follows: The double-disturbance soil loosening and root cutting Cistanche deserticola planter is attached to the suspension system of the tractor through the suspension frame. The input shaft of the transmission box of the soil loosening device is connected to the power output shaft of the tractor through the transmission shaft. The adjustment cylinder of the frame is connected to the hydraulic system of the tractor through the oil pipe.

[0023] After the seeder follows the tractor to the plot to be sown, it adjusts the depth of the extension rod of the loosening frame into the steel pipe of the crossbeam according to the planting row spacing and growth status of the plants parasitized by Cistanche deserticola, such as Haloxylon ammodendron, Tamarix chinensis, or Trigonella foenum-graecum, through the adjusting cylinder of the machine frame until the sowing row spacing meets the requirements; according to the planting years and growth status of the parasitized plants, it adjusts the position of the main root cutter of the loosening frame relative to the length direction of the column until the root cutting depth of the plants parasitized by Cistanche deserticola meets the requirements; and sets the sowing rate per acre as required.

[0024] After the tractor and seeder are accurately aligned at the edge of the field, the power take-off (PTO) lever of the tractor is moved to the engaged position. This activates the transmission box of the soil loosening device, which in turn drives the chain drive of the soil loosening assembly, thereby operating the double rocker arm mechanism. Simultaneously, the suspension system lever of the tractor is moved to the lower position. The suspension frame lowers the entire seeder via the frame, and the double rocker arm mechanism of the soil loosening assembly gradually cuts into the soil as it moves forward.

[0025] As the tractor drives the seeder, and then the frame drives the soil loosening component to run in the direction indicated by the "three-dimensional arrow" of the soil disturbing arrow, the crank of the double rocker mechanism can drive the two rocker arms I of rocker arm mechanism I to swing around the active end of the chain drive, and drive the two connecting rods II of rocker arm mechanism II to perform planar motion. Since the swing period of the two rocker arms I and the planar motion period of the two connecting rods II are 180° out of phase, the frame jumping caused by the swing of rocker arm mechanism I and the planar motion of rocker arm mechanism II can be effectively avoided, thus ensuring the stability and reliability of the seeder. The alternating disturbance of the two rocker arms I and the two connecting rods II can break up the soil and form a loose soil trough, laying the foundation for the successful sowing of Cistanche deserticola. In addition, the elastic limiting rod can effectively limit the distance between the two connecting rods II of the rocker mechanism II. This ensures that the two connecting rods II can move normally in a plane, and also effectively prevents the connecting rods II from swaying left and right due to changes in the hardness of the soil on both sides of the connecting rods II. This ensures the smooth implementation of the rocker mechanism II's soil disturbance operation and ensures the stable and reliable operation of the seeder.

[0026] Meanwhile, the lateral root cutter of the soil-loosening frame's soil-disturbing arrow can effectively cut off the lateral roots of the parasitic plants to stimulate the growth of more lateral roots. The soil-disturbing blade I can cut and disturb the soil on both sides, thereby making the soil loose. It can also increase the width of the loose soil groove formed by the double rocker mechanism of the soil-loosening component. While ensuring that the lateral sowing area of ​​the seeds remains unchanged, the cutting width of the soil-loosening component can be reduced to minimize energy consumption. The diversion blade can divert the soil in front of the column to both sides to avoid soil congestion in front of the column, thereby reducing the forward resistance of the seeder. In addition, when the soil disturber moves forward in the soil, if the sowing depth of the seeder fluctuates due to uneven soil or changes in soil hardness, causing the surfaces of disturber blades I and II to tilt, the impact force and friction generated by the soil on the surfaces of disturber blades I and II will push disturber blades I and II to swing in the opposite direction, thereby forcing the soil disturber to automatically return to a horizontal state and ensuring that the seeder always operates stably at the set sowing depth.

[0027] The seeder of the sowing device can automatically and precisely adjust the sowing drive speed according to the set sowing rate / acre, thus achieving precision sowing. After the seeder evenly distributes the Cistanche deserticola seeds into each seed guide tube, because the distance between the axis of each seed inlet section and the axis of the seed outlet section of the seed guide tube is not equal, and the distance between the axis of each seed inlet section and the axis of the seed outlet section in the direction of the seed inlet section of the seed guide tube is also not equal, the Cistanche deserticola seeds entering the seed guide tube will be evenly sown into the furrows within 400mm and throughout the entire width of the furrow when discharged from the seed outlet end of the seed guide tube. Therefore, three-dimensional full-area uniform sowing can be achieved throughout the entire furrow. The soil, which has become loose after being shredded by the double rocker mechanism, is then diverted by the diverting blade and bypasses the column. It is then thoroughly mixed with the seeds sown by the seeder of the sowing device, the roots of the plant parasitizing Cistanche deserticola cut by the main root cutter, and the soil shredded by the main root cutter. In addition, the collapse of the soil above the trench can bury all the Cistanche deserticola seeds in the trench, so as to ensure that the seeds are fixed in position, while retaining moisture and water, ensuring successful inoculation and rapid germination of the seeds.

[0028] After sowing, the telescopic rod of the loosening frame is inserted into the crossbeam steel pipe to the deepest point by adjusting the adjustment cylinder of the frame, so as to minimize the lateral width of the implement and improve the transportability of the seeder.

One right-angled side of both soil-disrupting blade I (1341) and soil-disrupting blade II (1342) extends vertically outward to form a mounting lug (1343). Thus, soil-disrupting blade I (1341) and mounting lug (1343), and soil-disrupting blade II (1342) and mounting lug (1343), all constitute a [missing information - likely a specific structure or feature]. The intersection of the other right-angled side and the hypotenuse forms an "arrow" shape at the vertex; two soil-disrupting blades I (1341) are symmetrically fixed to the two sides of a right-angled triangular plate-shaped side root cutter (1344) via the right-angled sides that do not extend from the mounting ears (1343), and the surfaces of the two soil-disrupting blades I (1341) are perpendicular to the surfaces of the side root cutter (1344). The surfaces of the two soil-disrupting blades I (1341) and one right-angled side of the side root cutter (1344) are located in the same plane, and the right-angled sides of the two soil-disrupting blades I (1341) with the mounting ears (1343) extending from the side root cutter (1344) are perpendicular to the surfaces of the two soil-disrupting blades I (1341). The other right-angled side of the 1344 is in the same plane, and the two mounting ears (1343) extend away from the side root cutter (1344); therefore, the angle formed by the right-angled side and the hypotenuse of the side root cutter (1344) and the soil disturber I (1341) plate surface in the same plane points in the same direction as the "arrow" of the two soil disturber I (1341); the two soil disturber II (1342) are symmetrically fixed on the two side plates of the side root cutter (1344) through the right-angled side that does not extend out of the mounting ears (1343), and the plate surface of the two soil disturber II (1342) is in the same direction as the side root cutter (1344).

Therefore, the "arrows" of the two soil disturbing blades II (1342) point in the same direction as the "arrows" of the two soil disturbing blades I (1341), thus the "arrows" of the two soil disturbing blades I (1341) are aligned.

The triangular prism plane formed by the other right-angled side of the two diverting blades (1345) is in the same plane as the right-angled side of the two soil disturbing blades I (1341) with the mounting ear (1343).The soil-disturbing arrow (134) is mounted on the side of the column (132) near the upright plate (131) via the mounting ears (1343) extending from the soil-disturbing blade I (1341) and soil-disturbing blade II (1342) and the triangular prism plane of the diverting blade (1345), with the "three-dimensional arrow" pointing away from the column (132). The surface of the soil-disturbing blade I (1341) is perpendicular to the length direction of the column (132), and the surface of the lateral root cutter (1344) is parallel to the length direction of the column (132). Therefore, during operation, the lateral root cutter (1344) can effectively cut the lateral roots of the parasitic plant to stimulate the growth of more lateral roots. The soil-disturbing blade I (1341) can cut and disturb the soil on both sides to increase the width of the trench. The diverting blade (1345) can divert the soil in front of the column (132) to both sides to avoid soil congestion in front of the column (132).
