[0023] In the existing technology, the planting of Astragalus on hillsides faces the problem of "no roads to go": "cows can go in, but oxen cannot", lack of mechanized farming conditions, and inconvenient application of agricultural machinery. In hilly and mountainous areas, there are many reasons for the low level of mechanization, the most important of which are unsuitable natural conditions and complex and backward basic production conditions. To achieve mechanized operation, first of all, there must be roads to go, otherwise agricultural machinery and equipment cannot go into the fields at all. The plots of land in hilly and mountainous areas are scattered, and there is a lack of mechanized farming roads in the fields, which makes it difficult for agricultural machinery to "go into the fields" and "operate". There are machines but they cannot be used, and it is even more troublesome to use machines. "No machines can be used": the terrain is complex and special, and there is a lack of agricultural machinery suitable for it. According to agricultural experts, more than two-thirds of the farmland in hilly and mountainous areas is sloping land, and the rest is terraced fields. Among them, slopes are divided into sloping farmland with a slope of 2-6 degrees, sloping farmland with a slope of 6-15 degrees, and sloping farmland with a slope of 15-25 degrees. Different types of sloping farmland have different requirements for agricultural machinery climbing and obstacle crossing, braking and steering, and adaptive adjustment of the lateral posture of the power chassis. Agricultural machinery companies have to independently develop agricultural machinery suitable for these cultivated lands. At present, the agricultural market lacks suitable agricultural machinery.

[0024] In the search of the present application, the patent number CN202320308628.2 was retrieved, and the name is a large-scale Astragalus harvester, including a vehicle body, a traction frame, wheels, a traction frame fixing block, a support frame, a breaking wheel, a guide belt, a lifting plate, a magnetic block, a cover plate, a connecting loose-leaf, a dust suction block, a first locking knob, a lifting rod, a tooth block, a clamping block, a transmission chain, a driving motor, a cleaning brush, a wheel cover, a guide groove and a second locking knob.

The vehicle body is slidably and telescopically connected to the lifting plate in the guide groove through the second locking knob, and the lifting plate is distributed in an inclined position on the vehicle body. The lifting plate is locked and fixedly connected to the vehicle body through the second locking knob, which makes it convenient to carry out the lifting plate. The sliding telescopic adjustment is convenient for adaptive use. The traction frame is distributed in a protruding position on one side of the upper end of the vehicle body, and the traction frame is connected to the traction frame fixing block in a lifting and moving manner through a lifting rod. The traction frame fixing block is locked and fixedly connected to the traction frame on the lifting rod through a first locking knob. In this way, the traction frame can conveniently adjust the lifting and lowering of the traction frame fixing block, which is convenient for adapting to different equipment and is more flexible to use. A wheel cover is installed on the upper end cover of the outer wall of the wheel, and one side of the wheel cover is fixedly connected to the vehicle body. The wheel cover is connected to the wheel in a vertical sweeping manner through a cleaning brush. In this way, the wheel can be cleaned of mud through the cleaning brush to avoid adhesion affecting movement. A support frame is fixedly connected to the upper edge of the vehicle body, and a connecting hinge is installed on one side of the upper end of the support frame. A cover plate is installed on the other side of the loose-leaf, and a dust suction block is installed on the inner wall of the cover plate, and a magnetic block is inlaid and installed on the edge of one end of the cover plate and the support frame, the cover plate is flipped and connected to the support frame by connecting the loose-leaf, and the support frame is magnetically fixed to the support frame through the magnetic block, the shape of the cover plate matches the shape of the dust suction block, and the dust suction block has a honeycomb structure, which makes it convenient to flip and open and close the cover plate, and the dust suction block can be used to effectively suction dust to avoid dust, a material guide belt is installed in the middle position of the inner wall of the vehicle body, and a tooth block is fixedly connected to the surface of the material guide belt, a lifting plate is installed on one side of the inner wall of the vehicle body, and a second locking knob is installed on one side of the lifting plate, the second locking knob is plugged into the guide groove, and the guide groove is opened on the side of the vehicle body, and a driving The present invention relates to a driving motor, and a transmission chain is installed on the outer wall of one end of the driving motor, a breaking wheel is installed on one end of the driving motor, and a clamping block is installed on the outer wall of the breaking wheel, the breaking wheels are symmetrically distributed on the inner wall of the vehicle body, and the breaking wheels are linked and rotated on the driving motor through the transmission chain, and the clamping blocks are clamped and rotated through the breaking wheels, the material guide belt is distributed on the inner wall of the vehicle body in three groups of inclined stepped positions, and the tooth blocks are unidirectionally evenly distributed on the material guide belt, so that the material guide belt can stably guide the material through the tooth blocks to avoid sliding, and the sticking soil can be broken up by the breaking wheel and the clamping block, so the separation effect is better, a lifting rod is installed on the traction frame, and a traction frame fixing block is installed at the lower end of the lifting rod, and a first locking knob is installed on the upper end of the side of the traction frame.

[0025] Working principle: When using the large-scale Astragalus harvester, first fix the device to the vehicle through the traction frame fixing block, then move the lifting plate downward through the guide groove, and lock it with the second locking knob, then flip the cover plate closed, and fix it to the support frame magnetically through the magnetic block, then use the vehicle to tow the device through the wheels, so that the lifting plate shovels up the Astragalus, and the Astragalus is pulled by the tooth block on the guide belt, and part of the soil is leaked out through its hollow structure, then the Astragalus is introduced into the breaking wheel, and then the breaking wheel and the clamping block are driven to rotate by the transmission chain and the drive motor, so that the soil adhering to the Astragalus is clamped and discharged, and the processed dust will be absorbed by the dust suction block, and when moving, the wheels can be continuously swept by the cleaning brush on the wheel cover to avoid soil adhesion. This is the use process of the large-scale Astragalus harvester.

[0026] However, the mechanical shape of this scheme is large, which is not easy to perform excavation operations in complex terrain. In addition, its harvesting method will turn over a large amount of soil, which is not conducive to maintaining soil properties and is prone to soil problems such as soil erosion.

[0027] Another patent with patent number CN202222912522.1 discloses a portable tree digging machine, including a mounting block, the lower surface of the mounting block is fixedly connected to the fixed end of the cylinder, the output end of the cylinder is fixedly connected to the upper surface of the lifting block, the lower surface of the lifting block is fixedly connected to the upper surface of the enclosure plate, a through groove is provided inside the lifting block, one end of the through groove is fixedly connected to one end of a water inlet pipe, the other end of the water inlet pipe is connected to a water supply source, the other end of the through groove is fixedly connected to one end of a hose, a horizontally arranged water pipe is fixedly installed on the inner side of the enclosure plate, a plurality of evenly distributed holes for connecting the water inlet of a sprinkler nozzle are provided on the water pipe, the sprinkler nozzle is fixedly connected to the water pipe, and the water outlet of the sprinkler nozzle faces downward, the lower surface of the lifting block is fixedly connected to one end of a first connecting rod, and the other end of the first connecting rod The fixed end of the shovel is threadedly connected, and the cylinder is started when digging trees, so that the shovel makes a reciprocating lifting and lowering motion in the soil, reducing the physical strength of the workers to insert the shovel into the soil and then pull it out. When the soil water content is low, the soil at the root of the tree is difficult to wrap the roots of the tree. When digging trees, the water supply equipment is started, and the sprinkler nozzle begins to water the ground, making the soil moist and increasing the water content. When the tree is dug out, the soil firmly wraps the roots of the tree, improving the survival rate of the dug trees. In the process of digging trees, the soil is too dry and dust will be generated. The water sprayed by the sprinkler nozzle makes the dust adsorbed in the water and turned into mud, reducing the impact of dust on residents' lives. The mud will splash when digging trees, and the baffle plate has a certain blocking effect on the splashing of mud, preventing the mud from splashing everywhere on the surrounding people.

[0028] The upper surface of the lifting block is fixedly connected to the motor, the output end of the motor passes through the lifting block and is fixedly connected to one end of the second connecting rod, the other end of the second connecting rod is threadedly connected to the auger rod. Before digging a tree, the shovel is removed and the auger rod is installed. The soil around the tree to be dug is loosened with the auger rod to facilitate the shovel to dig the tree later.

[0029] The fixed ends of the handles are fixed to the two sides of the mounting block, so that it is more convenient for people to take the tree digging machine through the handles, and the direction of digging trees can be controlled through the handles when the tree digging machine is working.

[0030] The outer surface of the handle is fixedly connected with an anti-skid layer. When people hold the handle for a long time, their palms will sweat. The outer surface of the handle is fixedly connected with an anti-skid layer, which increases the friction between the hand and the handle, making the tree digger more stable in the hand.

[0031] A filter is fixedly connected to the water inlet of the through slot. When the tree digger works outdoors, there is no pure water source and it can only obtain water through streams and rivers. There are inevitably some impurities in these waters. In order to prevent the impurities in the water from clogging the sprinkler nozzle, a filter is fixedly connected to the water inlet of the through slot to prevent impurities from affecting the water delivery function of the water pipe and the sprinkler nozzle.

[0032] One side of the mounting block is fixedly connected to the two first blocks, and a through hole is opened on the first block. A limit block is installed in the through hole by rotating a bolt, and the end of the bolt is threadedly connected to the limit nut. A limit clamp ring is fixedly connected to the side of the limit block away from the mounting block. When digging a tree, the limit clamp ring is fixed to the tree to be dug, so that the tree digger can work evenly around the tree, determine the diameter of the tree root system, and leave uniform soil around the roots of the dug trees to wrap the roots of the trees. When digging a tree, the angle between the tree digger and the soil is adjusted by the bolt, and the limit nut is used to clamp the first block and the limit block to generate friction. The friction force ensures that the angle will not change during the tree digging process, which is convenient for improving the efficiency of tree digging.

[0033] To sum up: when digging a tree, the cylinder is started so that the shovel can move up and down in the soil, reducing the physical effort of the worker to insert the shovel into the soil and then pull it out. When the soil moisture content is low, the soil at the root of the tree is difficult to wrap the roots of the tree. When digging a tree, the water supply equipment is started, and the sprinkler nozzle begins to water the ground to make the soil moist. When the tree is dug out, the soil firmly wraps the roots of the tree, which increases the survival rate of the dug out tree. In the process of digging a tree, the soil is too dry and will produce dust. The water sprayed by the sprinkler nozzle makes the dust adsorbed in the water and become mud. The mud will splash when digging the tree. The baffle has a certain blocking effect on the splashing of the mud, preventing the mud from splashing around on the people around. The soil around the tree to be dug is first loosened with a spiral drill rod to facilitate the subsequent digging of the tree with a shovel.

[0034] However, due to the weight, a single person cannot carry it uphill, and the integrity of the root system of Astragalus cannot be guaranteed, and the operation is complicated. This technology uses a diesel engine, which cannot continuously and efficiently carry out the work of digging Astragalus, will pollute the environment, and does not meet environmental protection factors.
