Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an automatic artemisia planter. Background Art

[0002] Artemisia selengensis, also known as Artemisia selengensis, Artemisia selengensis, and Artemisia selengensis, belongs to the genus Artemisia of the Asteraceae family and is a perennial herb.

[0003] Although mechanized equipment has been gradually introduced in the production process of Artemisia selengensis in the aspects of tillage, plant protection and transportation, the planting process, especially in the process of sowing and transplanting, still mainly relies on manual operation. Manual operation is not only labor-intensive and inefficient, but also easily leads to seedling loss, affecting the yield and quality of Artemisia selengensis. Therefore, mechanized planting has significant application advantages in improving operation efficiency, reducing labor intensity and reducing seedling loss.

[0004] At present, steel frame plastic greenhouses have become the main cultivation method for Artemisia selengensis. According to the survey, the common spans of steel frame plastic greenhouses are 6 meters and 8 meters, and a few use multi-span greenhouses. The shoulder height of the greenhouse is generally 1.2 to 1.3 meters, the length is 50 to 60 meters, and the furrows are opened along the length of the greenhouse, and the width of the furrow surface is 2 to 3 meters. This cultivation method provides a stable environmental condition for the cultivation of Artemisia selengensis, but it also puts forward specific requirements for the operating machinery.

[0005] Although the existing mechanized artemisia planting equipment has made some progress to a certain extent, there are still problems such as large equipment size and heavy weight, which limit the applicability of mechanical equipment in actual operations. In addition, the high production cost also makes it difficult to promote and apply the existing equipment in small-scale and most farmers, resulting in a gap between the actual operation effect and the expected goal. Therefore, further optimization and innovation of mechanized technology for artemisia planting has become an important issue that needs to be solved urgently. Optimizing mechanical design, reducing costs, and improving the adaptability and operating efficiency of equipment will significantly help the sustainable development of the artemisia industry. Summary of the invention

[0006] The invention aims to overcome the defects in the current technology and provides a new automatic artemisia planting machine.

[0007] The present invention is achieved through the following technical solutions:

[0008] An automatic artemisia planting machine, comprising:

[0009] The frame includes a body, an inclined seedling baffle installed on the body, and a horizontal front baffle, wherein the front baffle is located at the bottom of the seedling baffle; the width of the body is 0.8 to 1.0 m, and the length of the body is 0.8 to 1.0 m, and the height is 1.0 to 1.5 m. Based on the common width of the bed surface in the greenhouse being 2 to 3 m, the main design dimension of the planter is the width of the body;

[0010] The seedling-screening and delivering device and the seedling-screening and delivering power system are provided with four seedling-screening and delivering devices, and the four seedling-screening and delivering devices are all installed on the seedling-following baffle plate and are evenly spaced along the width direction of the vehicle body. The top of the seedling-screening and delivering device is provided with an inlet for bundles of Artemisia selengensis stems, and the bottom thereof is provided with an outlet for single Artemisia selengensis stems. A seedling-grabbing funnel fixed on the front baffle plate is provided below the outlet at the bottom of each seedling-screening and delivering device. The four seedling-grabbing funnels are evenly spaced along the left-right direction on the top surface of the front baffle plate, and a planting hole connected with the bottom outlet of the seedling-grabbing funnel is provided on the front baffle plate, so that the single Artemisia selengensis stem seedling falling into the seedling-grabbing funnel can be pressed into the soil through the planting hole. The seedling-screening and delivering device is used for screening the bundles of Artemisia selengensis stems into single Artemisia selengensis stems and delivering them into the seedling-grabbing funnel at intervals in sequence; the seedling-screening and delivering power system is used for driving the seedling-screening and delivering device to screen and deliver seedlings;

[0011] An eccentric wheel reciprocating intermittent planting mechanism, wherein two eccentric wheel reciprocating intermittent planting mechanisms are provided, and the two eccentric wheel reciprocating intermittent planting mechanisms are both installed on the top surface of the front baffle plate and are spaced apart along the width direction of the vehicle body, wherein one eccentric wheel reciprocating intermittent planting mechanism is provided between two seedling grafting funnels on the left side of the top surface of the front baffle plate, and is used to press a single Artemisia selengensis stem seedling falling into the two seedling grafting funnels into the soil, and the other eccentric wheel reciprocating intermittent planting mechanism is provided between two seedling grafting funnels on the right side of the top surface of the front baffle plate, and is used to press a single Artemisia selengensis stem seedling falling into the two seedling grafting funnels into the soil;

[0012] A traveling mechanism, the traveling mechanism comprising a plurality of farming wheels mounted on the vehicle body and a transmission system for synchronously driving the farming wheels to rotate and the eccentric wheel to reciprocate and intermittently press the seedlings of the planting mechanism;

[0013] The size design of the above-mentioned body and the installation and layout structure of the screening and seedling feeding device, the eccentric wheel reciprocating intermittent planting mechanism and the travel mechanism on the frame make the whole machine compact. Based on the common span of existing greenhouses of 6 to 8 meters, the shoulder height of 1.2 to 1.3 meters, the length of 50 to 60 meters, and the bed width of 2 to 3 meters in the greenhouse, the compact planter with the above-mentioned size design and layout structure is highly compatible with the working environment in the greenhouse. It has sufficient operating space in the greenhouse. The planter can flexibly respond to the operating needs in the greenhouse and can efficiently perform automated sowing operations. The compact size design and automated operation functions of the planter are particularly suitable for small-scale and most farmers' planting as well as greenhouse planting, which can greatly improve production efficiency, reduce manpower input, and contribute to the sustainable development of the artemisia selengensis industry.

[0014] Furthermore, the frame also includes a hand handle fixedly installed on the body of the vehicle at the rear side of the seedling baffle. The operator holds the hand handle with both hands to better stabilize the whole machine, and the whole machine will automatically move forward after the travel mechanism is started.

[0015] Furthermore, the sub-screening seedling delivery device comprises a sub-screening shell, a sub-screening shaft, a sub-screening wheel, a hopper enclosure and a stem seedling straightening mechanism; the main body of the sub-screening shell is a cylindrical structure, and a feed hopper communicated with the inside is arranged on the top of the cylindrical body, the sub-screening shell is screwed to the front side wall of the seedling baffle, and the central axis of the cylindrical body is perpendicular to the front side wall of the seedling baffle; the sub-screening shaft is rotatably arranged in the sub-screening shell and the rear end of the gear mechanism of the sub-screening shaft passes through the seedling baffle; the sub-screening wheel is installed in the sub-screening shell and fixed on the sub-screening shaft, so that it can rotate with the sub-screening shaft in the sub-screening shell, and the sub-screening seedling delivery power system can drive the sub-screening shafts of each sub-screening seedling delivery device to rotate synchronously;

[0016] The top of the feed hopper of the sub-screening shell is screwed with a hopper enclosure, which can put bundles of artemisia stems into the feed hopper of the sub-screening shell through the hopper enclosure, and the axial direction of the artemisia stems is in the same direction as the axial direction of the sub-screening shaft. The hopper enclosure can form an enclosure protection above the feed hopper of the sub-screening shell, deepen the depth of the feed hopper, and prevent the artemisia stems from falling out due to the vibration of the machine operation; the outer side wall of the sub-screening wheel is provided with a slot for accommodating a single artemisia stem, and the bottom of the cylindrical main body of the sub-screening shell is provided with a lower seedling through groove extending along the axial direction. The stem seedling straightening mechanism is arranged below the sub-screening shell, and a channel for a single artemisia stem to fall through is formed inside the stem seedling straightening mechanism. The top entrance of the internal channel of the stem seedling straightening mechanism is located directly below the lower seedling slot, and the bottom outlet of its internal channel is connected to the seedling receiving funnel. When the sub-screen wheel rotates with the sub-screen shaft and the slot on its outer wall is located below the feed hopper, a reed stem seedling in the lower hopper falls into the slot. As the sub-screen wheel continues to rotate, the sub-screen wheel carries the single reed stem seedling to the lower seedling slot at the bottom of the cylindrical body, and the single reed stem seedling can fall freely. After the single reed stem seedling comes out of the lower seedling slot, it turns from horizontal to vertical and falls. The upper section of the stem seedling straightening mechanism is wide and the lower section is narrow. The single reed stem seedling turns from horizontal to vertical in the stem seedling straightening mechanism and then falls downward into the seedling receiving funnel.

[0017] Furthermore, the stem seedling straightening mechanism is composed of a bent sheet metal part and a transparent cover. The bent sheet metal part is a trough-like structure that is wide at the top and gradually narrows at the bottom, and the lower side wall is open to facilitate observation whether there is material stuck therein. The transparent cover is a long strip of trough-like structure. A channel for a single Artemisia stem seedling to fall through is formed between the bent sheet metal part, the transparent cover and the front side wall of the seedling baffle. The top notch of the bent sheet metal part is located directly below the lower seedling through groove to facilitate the single Artemisia stem seedling to fall therein. The top notch of the transparent cover is connected with the bottom notch of the bent sheet metal part, and its bottom notch is connected with the seedling grafting funnel, so that the single Artemisia stem seedling falling longitudinally in the transparent cover can slide into the seedling grafting funnel. The opening inclination of the seedling grafting funnel corresponds to the inclination of the seedling grafting baffle, so that the single Artemisia stem seedling can slide smoothly into the seedling grafting funnel; it is also convenient to observe whether there is material stuck therein through the transparent cover.

[0018] Furthermore, the screening seedling feeding power system includes a screening motor, a screening double-row sprocket and a screening chain; the screening motor is fixedly mounted on the vehicle body; a screening double-row sprocket is fixedly mounted on the rear end of the screening shaft of each screening seedling feeding device, two adjacent screening double-row sprockets are respectively connected by a screening chain transmission, any one of the two outer side screening double-row sprockets is connected to the power output end of the screening motor by a screening chain transmission, the screening motor drives the other three screening double-row sprockets to rotate by controlling a screening double-row sprocket on the front or rear side, and the screening seedling unloading time of each screening seedling feeding device can be controlled by controlling the rotation speed of the screening motor.

[0019] Furthermore, each of the eccentric wheel reciprocating intermittent planting mechanisms includes two planting side plates and a driving shaft and a driven shaft;

[0020] Two planting side plates are arranged parallel and spaced along the left and right directions on the top surface of the front baffle plate, and are both located between the two seedling inoculation funnels;

[0021] The driving shaft and the driven shaft are arranged in parallel between the tops of the two planting side plates, and both ends thereof are rotatably connected with the planting side plates, so that the driving shaft and the driven shaft can rotate on the tops of the two planting side plates;

[0022] A small sprocket is fixedly installed in the middle of the driving shaft. The transmission system of the travel mechanism can drive the small sprocket to rotate and thus drive the driving shaft to rotate. The small sprocket is located between the two planting side plates. Both ends of the driving shaft are fixedly installed with driving incomplete gears. Both ends of the driven shaft are fixedly installed with driven complete gears. The driving incomplete gear and the driven complete gear cooperate to form an incomplete gear mechanism for driving the driven complete gear to intermittently move.

[0023] Both ends of the driven shaft are fixedly installed with eccentric wheel discs, and are located on the outside of the driven complete gear; each eccentric wheel disc is screwed and fixed with an eccentric wheel connecting rod, and one end of each eccentric wheel connecting rod away from the eccentric wheel disc is screwed and fixed with a cutting push rod, and the outer wall of each planting side plate is screwed with a guide fixing seat, and a guide hole communicating with each other up and down is opened on the guide fixing seat, and the cutting push rod is installed in the guide hole, and the central axis of the cutting push rod is coaxial with the central axis of the seedling grafting funnel, and the guide fixing seat can constrain the movement direction of the cutting push rod. When the eccentric wheel disc rotates intermittently with the driven shaft, it can drive the cutting push rod to rise and fall in the vertical direction through the eccentric wheel connecting rod to perform intermittent planting of a single Artemisia selengensis stem seedling in the seedling grafting funnel, ensuring that the cutting push rod can press the Artemisia selengensis stem seedling in the seedling grafting funnel into the soil vertically downward;

[0024] The eccentric wheel reciprocating intermittent planting mechanism presses the single Artemisia selengensis seedling falling into the seedling grafting funnel into the soil by gap planting. As the whole machine moves forward, the Artemisia selengensis seedlings can be planted at intervals along the length direction of the greenhouse on the ridges in the greenhouse, which is beneficial to improving the planting survival rate of the Artemisia selengensis seedlings.

[0025] Furthermore, the transmission system of the travel mechanism includes a main drive reduction motor and two wheel axles; the main drive reduction motor is a double-output shaft reducer, which is fixedly mounted on the top surface of the front end baffle on the rear side of the seedling baffle; the two wheel axles are coaxially arranged and are respectively mounted on the vehicle body through bearing seats, and the inner ends of the two wheel axles are respectively fixedly connected to the two power output ends of the main drive reduction motor, so that the main drive reduction motor can drive the two wheel axles to rotate synchronously, and the two farming wheels are provided with two, and the two farming wheels are respectively fixedly mounted on the outer ends of the two wheel axles, and the main drive reduction motor can drive the two farming wheels to rotate synchronously as the forward driving force of the whole machine, and the front end of the front end baffle is equipped with two universal wheels spaced left and right for controlling the steering of the whole machine; a battery pack for powering the screening motor and the main drive reduction motor is installed on the vehicle body on the rear side of the seedling baffle;

[0026] A driving sprocket is fixedly installed on each wheel axle. The two driving sprockets are opposite to the small sprockets of the two eccentric wheel reciprocating intermittent planting mechanisms and are connected through chain transmission, so that the main transmission reduction motor can drive the small sprocket to rotate while driving the farming wheel, thereby realizing intermittent planting while the whole machine moves forward, so as to plant artemisia stems at intervals on the ridges in the greenhouse along the length direction of the greenhouse.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] (1) The automatic planter of Artemisia selengensis of the present invention realizes fully automated control in delivering seedlings. Compared with the prior art, the present invention can obtain the most efficient planting speed by designing an incomplete gear intermittent mechanism in conjunction with a screening seedling delivery device to calculate the optimal rotation speed, while avoiding the stuck and broken Artemisia selengensis stems. The eccentric wheel reciprocating intermittent planting mechanism is controlled by the wheel shaft and linked with the traveling mechanism. The transmission of the whole machine is a purely mechanical structure, and the operation is reliable.

[0029] (2) The size design of the body of the automatic reed planter of the present invention and the installation and arrangement structure of the screening and seedling feeding device, the eccentric wheel reciprocating intermittent planting mechanism and the traveling mechanism on the frame make the whole machine compact. Based on the common span of existing greenhouses of 6 to 8 meters, the shoulder height of 1.2 to 1.3 meters, the length of 50 to 60 meters, and the width of the bed surface in the greenhouse of 2 to 3 meters, the compact planter with the above size design and arrangement structure is highly compatible with the working environment in the greenhouse. It has sufficient operating space in the greenhouse. The planter can flexibly respond to the working needs in the greenhouse and can efficiently perform automated sowing operations. The compact size design and automated operation function of the planter can greatly improve production efficiency, reduce manpower input, and help the sustainable development of the reed industry.

[0030] (3) Compared with the traditional artemisia planting machine, the automatic artemisia planting machine of the present invention adopts a simplified mechanical structure in the overall structural design, and the production cost is much lower than that of similar products in terms of material selection, manufacturing process optimization and cost control. The automatic planting machine is particularly suitable for small-scale and most farmers as well as greenhouse planting environments. The plant spacing on the ridge can be calculated and adjusted by the chain transmission ratio between the active sprocket and the small sprocket and the gear transmission ratio on the eccentric wheel reciprocating intermittent planting mechanism, which can achieve high-density planting with a planting row spacing of 20 to 25 cm, providing an efficient, reliable and economical planting plan for the greenhouse planting of artemisia.

[0039] An automatic artemisia planting machine, such as Figures 1 to 4 As shown, it is mainly composed of a frame 1, a screening and seedling feeding device 2, a screening and seedling feeding power system, an eccentric wheel reciprocating intermittent planting mechanism 4, a traveling mechanism 5, a battery pack 6 and a universal wheel 7.

[0040] like Figure 1 and Figure 4As shown, the frame 1 includes a body 1-1, an inclined seedling baffle 1-2 fixed to the body 1-1 by screws, a horizontal front baffle 1-3, and a hand handle 1-4 fixedly installed on the body 1-1 and located at the rear side of the seedling baffle 1-2, and the front baffle 1-3 is located at the bottom of the seedling baffle 1-2; the operator slightly holds the hand handle 1-4 with both hands to better stabilize the whole machine, and the whole machine will automatically move forward after the travel mechanism 5 is started; specifically, the hand handle 1-4 is a U-shaped structure, and its two ends are welded to the top rear side of the body 1-1;

[0041] The width of the vehicle body 1-1 is 0.8-1.0 m, the length of the vehicle body 1-1 is 0.8-1.0 m, and the height is 1.0-1.5 m;

[0042] Preferably, in this embodiment, the width dimension of the vehicle body 1-1 is 0.8m, the length dimension is 0.8m, and the height dimension is 1.0m. Based on the fact that the width of the bed surface in a greenhouse is usually 2 to 3m, the main design dimension of the planter is the width dimension of the vehicle body 1-1.

[0043] like Figure 1 As shown, there are four screening seedling delivery devices 2, which are all installed on the seedling baffle 1-2 and are evenly spaced along the width direction of the vehicle body 1-1. The top of the screening seedling delivery device 2 is provided with an inlet for bundled Artemisia selengensis stems, and the bottom is provided with an outlet for single Artemisia selengensis stems. Below the outlet at the bottom of each screening seedling delivery device 2 is a seedling receiving funnel 3 fixed on the front baffle 1-3. The four seedling receiving funnels 3 are evenly spaced along the left and right directions on the top surface of the front baffle 1-3, and A planting hole connected to the bottom outlet of the seedling grafting hopper 3 is provided on the front baffle plate 1-3, so that the single Artemisia selengensis seedlings falling into the seedling grafting hopper 3 can be pressed into the soil from the planting hole. The screening and seedling delivery device 2 is used to screen the bundled Artemisia selengensis seedlings into single Artemisia selengensis seedlings and sequentially deliver the single Artemisia selengensis seedlings into the seedling grafting hopper 3 at intervals. It should be noted that the width direction of the vehicle body 1-1 refers to the axle direction of the farming wheels 5-6, which is perpendicular to the travel direction thereof. The screening and seedling delivery power system is used to drive the screening and seedling delivery device 2 to screen and deliver the seedlings.

[0044] Specifically, Figure 1 and Figure 2As shown, the sub-screening seedling feeding device 2 includes a sub-screening shell 2-4, a sub-screening shaft 2-6, a sub-screening wheel 2-1, a hopper enclosure 2-2 and a stem seedling straightening mechanism; the main body of the sub-screening shell 2-4 is a cylindrical structure, and a feed hopper connected to the inside of the cylindrical body is arranged on the top of the cylindrical body, and the sub-screening shell 2-4 is screwed to the front side wall of the seedling baffle 1-2, and the central axis of the cylindrical body is perpendicular to the front side wall of the seedling baffle 1-2; the sub-screening shaft 2-6 is rotatably arranged in the sub-screening shell 2-4 and its (the sub-screening shaft 2-6) rear end penetrates The seedling baffle 1-2 is passed through, specifically, a through hole is provided on the seedling baffle 1-2 for the sub-screening shaft 2-6 to pass through and rotate therein; the sub-screening wheel 2-1 is installed in the sub-screening housing 2-4 and fixed on the sub-screening shaft 2-6, so that it can rotate with the sub-screening shaft 2-6 in the sub-screening housing 2-4, and the sub-screening seedling delivery power system can drive the sub-screening shaft 2-6 of each sub-screening seedling delivery device 2 to rotate synchronously; specifically, the front side of the sub-screening wheel 2-1 is a screwed end cover 2-3, so as to facilitate the disassembly and assembly of the sub-screening wheel 2-1 and the sub-screening shaft 2-6;

[0045] The top of the feed hopper of the sub-screening shell 2-4 is screwed with a hopper enclosure 2-2, and the top opening of the hopper enclosure 2-2 is the inlet for the bundled Artemisia stalks of the sub-screening seedling feeding device 2, and the bundled Artemisia stalks can be put into the feed hopper of the sub-screening shell 2-4 through the hopper enclosure 2-2, and the axial direction of the Artemisia stalks is in the same direction as the axial direction of the sub-screening shaft 2-6. The hopper enclosure 2-2 can form an enclosure protection above the feed hopper of the sub-screening shell 2-4, deepen the depth of the feed hopper, and prevent the Artemisia stalks from falling out due to the vibration of the machine operation; the outer side wall of the sub-screening wheel 2-1 is provided with a slot for accommodating a single Artemisia stalk, and the bottom of the cylindrical main body of the sub-screening shell 2-4 is provided with a lower seedling through groove extending along the axial direction, and the stem seedling straightening mechanism is arranged below the sub-screening shell 2-4, and the interior of the stem seedling straightening mechanism is formed with a channel for a single Artemisia stalk to fall through. The top entrance of the internal channel of the stem seedling straightening mechanism is located directly below the lower seedling slot, and the bottom outlet of its internal channel is connected to the seedling receiving funnel 3. When the sub-screen wheel 2-1 rotates with the sub-screen shaft 2-6 and the slot of its outer wall is located below the feed hopper, a reed stem seedling in the lower hopper falls into the slot. Specifically, the outer wall of the sub-screen wheel 2-1 is in gap contact with the inner wall of the cylindrical main body of the sub-screen shell 2-4, so that only one reed stem seedling can fall into the slot. As the sub-screen wheel 2-1 continues to rotate, the sub-screen wheel 2-1 carries the single reed stem seedling to the lower seedling slot at the bottom of the cylindrical main body, and the single reed stem seedling can fall freely. After the single reed stem seedling comes out of the lower seedling slot, it changes from horizontal to vertical and falls downward. The upper section of the stem seedling straightening mechanism is wide and the lower section is narrow. After the single reed stem seedling changes from horizontal to vertical in the stem seedling straightening mechanism, it falls downward into the seedling receiving funnel 3.

[0046] like Figure 1 and Figure 2As shown, the stem seedling straightening mechanism is composed of a bent sheet metal part 2-5 and a transparent cover 2-11. The bent sheet metal part 2-5 is a trough-like structure with a wide upper part and a gradually narrowed lower part, and the lower side wall is open to facilitate observation of whether there is material stuck therein. The transparent cover 2-11 is a long strip trough-like structure. A channel for a single Artemisia selengensis stem seedling to fall through is formed between the bent sheet metal part 2-5, the transparent cover 2-11 and the front side wall of the seedling baffle 1-2; the top notch of the bent sheet metal part 2-5 is located directly below the lower seedling through groove to facilitate a single Artemisia selengensis stem seedling to fall therein, and the top notch of the transparent cover 2-11 is connected with the bottom notch of the bent sheet metal part 2-5. The bottom notch thereof is connected with the seedling receiving funnel 3, and the bottom notch of the bent sheet metal 2-5 is the single Artemisia selengensis stem seedling outlet of the screening and seedling feeding device 2. The single Artemisia selengensis stem seedling falling longitudinally in the transparent cover 2-11 can slide into the seedling receiving funnel 3. The opening inclination of the seedling receiving funnel 3 corresponds to the inclination of the seedling following baffle 1-2, so that the single Artemisia selengensis stem seedling can slide smoothly into the seedling receiving funnel 3; it is also convenient to observe whether there is material stuck inside through the transparent cover 2-11. Specifically, the transparent cover 2-11 is made of transparent glass or transparent plastic, and the two vertical sides of the bent sheet metal 2-5 and the transparent cover 2-11 are integrally formed with flanges that can be screwed on the seedling following baffle 1-2.

Figure 1The sub-screening double-row sprocket 2-7 on the first sub-screening shaft 2-6 on the far left drives the sub-screening double-row sprocket 2-7 on the second sub-screening shaft 2-6 on the far left through the sub-screening chain 2-8, the sub-screening double-row sprocket 2-7 on the second sub-screening shaft 2-6 on the far left drives the sub-screening double-row sprocket 2-7 on the third sub-screening shaft 2-6 on the far left through the sub-screening chain 2-8, the sub-screening double-row sprocket 2-7 on the third sub-screening shaft 2-6 on the far left drives the sub-screening double-row sprocket 2-7 on the far right sub-screening shaft 2-6 through the sub-screening chain 2-8, and the sub-screening seedling unloading time of each sub-screening seedling feeding device 2 is controlled by controlling the rotation speed of the sub-screening motor 2-9, and the sub-screening motor 2-9 is controlled by a switch button installed on the top of the vehicle body 1-1.

[0049] like Figure 1 As shown, the eccentric wheel reciprocating intermittent planting mechanism 4 is provided with two, and the two eccentric wheel reciprocating intermittent planting mechanisms 4 are both installed on the top surface of the front baffle plate 1-3 and are spaced apart along the width direction of the vehicle body 1-1, one of the eccentric wheel reciprocating intermittent planting mechanisms 4 is arranged between the two seedling grafting funnels 3 on the left side of the top surface of the front baffle plate 1-3, and is used to press the single Artemisia selengensis stem seedlings falling into the two seedling grafting funnels 3 into the soil, and the other eccentric wheel reciprocating intermittent planting mechanism 4 is arranged between the two seedling grafting funnels 3 on the right side of the top surface of the front baffle plate 1-3, and is used to press the single Artemisia selengensis stem seedlings falling into the two seedling grafting funnels 3 into the soil;

[0050] Specifically, Figure 1 and Figure 3 As shown, each of the eccentric wheel reciprocating intermittent planting mechanisms 4 includes two planting side plates 4-15, a driving shaft 4-3 and a driven shaft 4-4;

[0051] The two planting side panels 4-15 are arranged parallel and spaced along the left-right direction on the top surface of the front baffle 1-3, and are both located between the two seedling funnels 3. Specifically, a planting base 4-1 is provided at the bottom end of each planting side panel 4-15, and the planting base 4-1 is screwed to the top surface of the front baffle 1-3, so that the planting side panel 4-15 is fixed on the front baffle 1-3, and an upper cover plate 4-16 is screwed between the tops of the two planting side panels 4-15, which can improve the stability of the two planting side panels 4-15;

[0052] The driving shaft 4-3 and the driven shaft 4-4 are arranged in parallel between the tops of the two planting side plates 4-15, and both ends thereof are rotatably connected with the planting side plates 4-15. Specifically, both ends of the driving shaft 4-3 and both ends of the driven shaft 4-4 are respectively installed on the tops of the planting side plates 4-15 through deep groove ball bearings 4-2, so that the driving shaft 4-3 and the driven shaft 4-4 can rotate on the tops of the two planting side plates 4-15;

[0053] A small sprocket 4-7 is fixedly installed in the middle of the driving shaft 4-3. Specifically, the small sprocket 4-7 is fixed on the driving shaft 4-3 as a source of power transmission by means of a flat key positioning and a sprocket set screw 4-8 positioning. The transmission system of the traveling mechanism 5 can drive the small sprocket 4-7 to rotate, thereby driving the driving shaft 4-3 to rotate. The small sprocket 4-7 is located between the two planting side plates 4-15; both ends of the driving shaft 4-3 are fixedly installed with a driving incomplete gear 4-9. Specifically, the driving incomplete gear 4-9 is fixed to the driving shaft 4-3 by means of a shoulder and a flat key positioning; both ends of the driven shaft 4-4 are fixedly installed with a driven complete gear 4-10. The driving incomplete gear 4-9 cooperates with the driven complete gear 4-10 to form an incomplete gear mechanism for driving the driven complete gear 4-10 to intermittently move;

[0054] Eccentric wheel discs 4-11 are fixedly installed at both ends of the driven shaft 4-4 and are located on the outside of the driven complete gear 4-10. Specifically, the ends of the driving shaft 4-3 and the driven shaft 4-4 are provided with shaft fixing end covers 4-5 and end cover screws 4-6. The driving incomplete gear 4-9, the driven complete gear 4-10 and the eccentric wheel disc 4-11 are fixed by shaft shoulders, flat key positioning, shaft fixing end covers 4-5 and end cover screws 4-6; an eccentric wheel connecting rod 4-12 is screwed and fixed on each eccentric wheel disc 4-11, and an insertion push rod 4-13 is screwed and fixed on the end of each eccentric wheel connecting rod 4-12 away from the eccentric wheel disc 4-11. The outer side walls of the planting side plates 4-15 are all screwed with guide fixing seats 4-14, and guide fixing seats 4-14 are provided with guide holes communicating with each other from top to bottom. The cutting push rod 4-13 is installed in the guide hole, and the central axis of the cutting push rod 4-13 is coaxial with the central axis of the seedling inoculation funnel 3. The guide fixing seat 4-14 can constrain the movement direction of the cutting push rod 4-13. When the eccentric wheel disc 4-11 rotates intermittently with the driven shaft 4-4, the cutting push rod 4-13 can be driven to rise and fall in the vertical direction through the eccentric wheel connecting rod 4-12 to intermittently plant a single Artemisia selengensis stem seedling in the seedling inoculation funnel 3, ensuring that the cutting push rod 4-13 can vertically press the Artemisia selengensis stem seedling in the seedling inoculation funnel 3 into the soil downward;

[0055] The above-mentioned eccentric wheel reciprocating intermittent planting mechanism 4 presses the single Artemisia selengensis seedlings falling into the seedling grafting funnel 3 into the soil through gap planting. As the whole machine moves forward, the Artemisia selengensis seedlings can be planted at intervals on the ridges in the greenhouse along the length direction of the greenhouse, which is beneficial to improving the planting survival rate of the Artemisia selengensis seedlings.

[0056] like Figure 1 and Figure 4 As shown, the traveling mechanism 5 includes two farming wheels 5-6 mounted on the vehicle body 1-1 and a transmission system for synchronously driving the farming wheels 5-6 to rotate and the eccentric wheel reciprocating intermittent planting mechanism 4 to press the seedlings;

[0057] The transmission system of the traveling mechanism 5 includes a main transmission reduction motor 5-2 and two wheel axles 5-1; the main transmission reduction motor 5-2 is a double-output shaft reducer, which is fixedly mounted on the top surface of the front end baffle 1-3 on the rear side of the seedling baffle 1-2; the two wheel axles 5-1 are coaxially arranged and are respectively mounted on the vehicle body 1-1 through bearing seats 5-5, and the inner ends of the two wheel axles 5-1 are respectively fixedly connected to the two power output ends of the main transmission reduction motor 5-2, specifically, the wheel axle 5-1 is connected to the main transmission reduction motor 5-2 through a coupling 5-4, so that the main transmission reduction motor 5-2 can drive the two wheel axles 5-1 to rotate synchronously;

[0058] The two farming wheels 5-6 are fixedly mounted on the outer ends of the two wheel axles 5-1 respectively, and the main drive reduction motor 5-2 can drive the two farming wheels 5-6 to rotate synchronously as the forward driving force of the whole machine. The front end of the front baffle 1-3 is equipped with two universal wheels 7 spaced apart on the left and right to control the steering of the whole machine; a battery pack 6 for powering the screening motor 2-9 and the main drive reduction motor 5-2 is installed on the body 1-1 on the rear side of the seedling baffle 1-2; the main drive reduction motor 5-2 is controlled by a switch button installed on the top of the body 1-1;

[0059] A driving sprocket 5-3 is fixedly installed on each wheel axle 5-1. The two driving sprockets 5-3 are opposite to the small sprockets 4-7 of the two eccentric wheel reciprocating intermittent planting mechanisms 4 and are connected through chain transmission. Specifically, two channels are provided on the seedling baffle 1-2 for the chains to pass through the driving sprocket 5-3 and the small sprocket 4-7 respectively. The main transmission reduction motor 5-2 drives the farming wheel 5-6 to rotate and can drive the small sprocket 4-7 to rotate at the same time, thereby realizing intermittent planting while the whole machine moves forward, so as to plant the Artemisia selengensis seedlings at intervals on the ridges in the greenhouse along the length direction of the greenhouse.

[0060] The working principle of the Artemisia automatic planter is as follows:

[0061] Put the prepared Artemisia selengensis stems into the lower hopper at the top of the screening shell 2-4 of each screening seedling feeding device 2 in bundles, and put the Artemisia selengensis stems into the lower hopper horizontally in bundles, ensuring that the axial direction of the Artemisia selengensis stems in the lower hopper is in the same direction as the central axis of the cylindrical body of the screening shell 2-4;

[0062] When the whole machine is working, the staff turns on the switch button to start the operation of the screening seedling feeding device 2, the eccentric wheel reciprocating intermittent planting mechanism 4 and the traveling mechanism 5, and the whole machine starts working; the transmission ratio of the chain drive between the active sprocket 5-3 on the wheel shaft 5-1 and the small sprocket 4-7 of the eccentric wheel reciprocating intermittent planting mechanism 4 is matched with the intermittent movement time calculation and control of the eccentric wheel reciprocating intermittent planting mechanism 4, so that when the Artemisia selengensis seedlings fall to the seedling receiving funnel 3 perpendicular to the ground, the eccentric wheel reciprocating intermittent planting mechanism 4 performs a planting, and the cutting push rod 4-13 presses the Artemisia selengensis seedlings in the seedling receiving funnel 3 into the soil and returns them to their original positions, and the eccentric wheel reciprocating intermittent planting mechanism 4 enters a gap state under the characteristics of an incomplete gear mechanism to prevent the Artemisia selengensis seedlings from being broken or damaged during the planting traveling state; when the second wave of Artemisia selengensis seedlings enter the seedling receiving funnel 3 and are perpendicular to the ground, a second planting is performed, and so on and so forth;

[0063] The spacing between plants on the ridge is calculated and adjusted by the chain transmission ratio between the active sprocket 5-3 and the small sprocket 4-7 and the gear transmission ratio on the eccentric wheel reciprocating intermittent planting mechanism 4. The actual working efficiency of the whole machine is determined by the rotation speed of the sub-screening shaft 2-6 of the sub-screening seedling feeding device 2. The staff only needs to slightly support the whole machine to control the stability of the whole machine and ensure that the prepared bundles of Artemisia selengensis stems are placed in the lower hopper of the sub-screening shell 2-4 in time; when turning is required, the switch button needs to be turned off, and the hand handle 1-4 is supported to turn under the steering action of the universal wheel 7. The weight of the whole machine is light, and the staff can turn by hand.
