Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a planting machine for wolfberry cultivation, and more particularly to an automated planting machine suitable for large wolfberry seedlings with nutrient bags attached to their roots. Background Technology

[0002] Container-grown goji berry seedlings are propagated through cuttings in nutrient bags. They are transplanted along with the bags, offering advantages such as rapid growth and high survival rates. However, precisely because the roots are attached to the nutrient bags, and the resulting seedlings can reach a height of 60-80cm, existing tree planting machinery cannot be used directly. Currently, the planting of container-grown goji berry seedlings mainly relies on manual labor, which is inefficient, labor-intensive, and costly, becoming a bottleneck restricting the industrialization and large-scale development of the goji berry industry.

[0003] While existing technologies include a "double-row goji berry seedling planting machine" disclosed in patent document CN115553137A, these are primarily designed for planting traditional bare-root or cutting seedlings. They utilize trenching and cutting mechanisms, and their structure and working principle are not suitable for planting tall goji berry container seedlings that require overall placement. Therefore, there is an urgent need for a mechanized planting device specifically designed for goji berry container seedlings, especially large seedlings. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a goji berry container seedling transplanting machine, which can realize the continuous operation of automated pit opening, precise seedling placement, reliable planting and simultaneous irrigation of large goji berry container seedlings, effectively improving planting efficiency and survival rate, and reducing labor costs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is to provide a wolfberry container seedling transplanting machine, including a frame, a transmission mechanism, a transplanting mechanism, a seedling feeding mechanism and an irrigation mechanism.

[0006] The frame has a frame structure, with a walking frame with wheels at the bottom and a towing frame at the front for connecting to a tractor.

[0007] The transmission mechanism is fixed to the front side of the frame and includes a power box and a gearbox, used to obtain power from the tractor and output it after speed change.

[0008] The planting mechanism is the core operating component, comprising a planting drive mechanism, a planting lifting bar, and a seedling planter. The planting drive mechanism receives power from the transmission mechanism, and its drive component employs a crank-connecting rod structure to convert rotational motion into reciprocating oscillation. The tail end of the planting lifting bar is hinged to the frame, and the middle part is hinged to the crank-connecting rod, thus being driven to perform periodic lifting and lowering motions. The seedling planter is fixed to the head end of the planting lifting bar, and its unique design includes a duckbill-shaped elastic opening device. This opening device is normally closed by built-in elasticity and is connected to the opening brake on the planting drive mechanism via an opening control rope. Through a cleverly designed linkage mechanism, when the planting device moves to its lowest point (the pit-opening position) with the lifting lever, the opening brake activates, tightening the control rope and forcibly opening the duckbill to create a planting pit and release the seedling. As the planting device begins to rise, the duckbill remains open to ensure the seedling is completely detached. When it reaches its highest point (the seedling-receiving position), the opening brake resets, the control rope loosens, and the duckbill automatically closes under elastic force, preparing for the next operation. This process achieves precise synchronization between pit opening and seedling planting.

[0009] The seedling feeding mechanism is responsible for automatically feeding seedlings to the planting device. It includes a seedling tray fixing frame, a rotating seedling tray, and a seedling tray transmission mechanism. Multiple seedling boxes are evenly arranged circumferentially on the rotating seedling tray, each seedling box having a bottom plate that can be opened in one direction. The seedling tray transmission mechanism is linked to the driving component of the planting drive mechanism. The linkage timing is set as follows: whenever the planting lifting lever raises the planting device to its highest point and the seedling receiving frame aligns with the seedling feeding opening on the seedling tray fixing frame, the linkage is triggered, and the seedling tray transmission mechanism drives the rotating seedling tray to rotate precisely one position, causing the bottom plate of the seedling box above the feeding opening to automatically open and feed a wolfberry container seedling into the seedling receiving frame of the planting device below. After the seedling box leaves the feeding opening, its bottom plate is pushed back and closed by the side edge of the seedling tray fixing frame, facilitating manual replenishment of seedlings.

[0010] As a further improvement to the invention, an irrigation mechanism is also provided. This mechanism includes a water tank, a pressure pump, a water delivery pipe, a spring-loaded closed-mouth irrigation valve, and a valve tension rope. The spring-loaded closed-mouth irrigation valve is installed on the frame at a certain distance behind the seedling planter, a distance equal to the planting spacing between two adjacent seedlings. The valve tension rope connects the valve's opening mechanism to another opening brake on the seedling tray transmission mechanism. Through the transmission mechanism, when the seedling planter is at its lowest point, opening a new pit and planting a new seedling, the seedling tray transmission mechanism triggers the opening brake, tightening the valve tension rope, opening the spring-loaded closed-mouth irrigation valve, and the pressure pump sprays water from the water tank, precisely irrigating the previously planted seedlings. Subsequently, the opening brake disengages, and the valve automatically closes. This design achieves synchronization between planting and irrigation, greatly improving operational efficiency and plant protection effectiveness.

[0011] In addition, the frame is also equipped with a container seedling replenishment rack, a seat, a water tank support, and a foldable foot pedal, which facilitates the operator's replenishment, operation, and rest, thus optimizing the ergonomics.

[0012] The beneficial effects of this invention are as follows: Designed specifically for the unique structure of large container-grown goji berry seedlings (with nutrient bags and high plant height), this machine represents the first to achieve fully mechanized planting of such seedlings, filling a technological gap. Through mechanized linkage, multiple processes—pit preparation, seedling placement, planting, and watering—are seamlessly integrated with precise timing, ensuring consistent and high-quality operations. Completing multiple tasks in one go significantly increases efficiency compared to manual labor, greatly meeting the cost-saving and efficiency-enhancing needs of industrialized goji berry cultivation. Standardized mechanized operations allow for controlled planting depth and spacing, coupled with synchronized, targeted watering, providing excellent initial growth conditions for the seedlings and improving transplant survival rates. The compact machine is compatible with common tractors, requiring operators to only perform replanting tasks, significantly reducing labor intensity. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0021] like Figures 1 to 5 As shown, the wolfberry container seedling transplanting machine of the present invention has a frame 1 made of welded steel sections forming a rectangular frame. Two walking frames 11 are symmetrically installed at the front and rear positions of the bottom of the frame 1 by bolts. The adjustable support legs 111 of each walking frame 11 can be adjusted in length by threads, thereby adjusting the height of the frame off the ground to adapt to different terrains and operational requirements. The bottom of the adjustable support legs 111 is equipped with walking wheels 112. The towing frame 12 is welded to the front end of the frame 1 for attachment to tractors or other towing vehicles.

[0022] The transmission mechanism 2 is bolted to the front of the frame 1. The input shaft of the power box 21 is connected to the power take-off shaft (PTO) of the tractor via a universal joint to obtain rotational power. The gearbox 22 is integrated with or connected in series with the power box 21 to adjust the output speed and torque, and its output shaft transmits power to the stationary drive mechanism 31 via chain or gear transmission.

[0023] In the planting mechanism 3, the main body of the planting drive mechanism 31 is fixed to the crossbeam in the middle of the frame 1. Internally, it contains a gear transmission group that converts the rotational motion of the input shaft into crank rotation. The crank is hinged to the middle of the planting lifting rod 32 via a connecting rod. The planting lifting rod 32 is a long rod, its tail end of which is hinged to a support at the rear of the frame 1 via a pin, thus forming a swing arm. The seedling planter 33 is welded to the head end of the planting lifting rod 32. Figure 3 As shown, the seedling receiving frame 331 of the seedling planter 33 is an open frame at the top, used to receive seedlings. The elastic opening device 332 consists of two duckbill-shaped steel plates hinged together by a pivot. A compression spring is installed between the tails of the two steel plates, giving it a tendency to be normally closed. A protruding latch is provided on the inner side of the duckbill plate near the pivot as an opening mechanism. The opening control rope 333 is made of steel wire rope, one end of which is tied to the latch, and the other end extends upward, passes over the guide pulley, and is connected to a cam or lever (i.e., the opening brake 311) specially set on the crank shaft of the planting drive mechanism 31. When the crank rotates and the planting lifting lever 32 moves to the lowest point, the cam profile pushes the opening control rope 333 outward, making it taut, thereby overcoming the spring force and opening the duckbill. This open state will continue until the planting lifting lever 32 rises to near the highest point, the cam profile changes, releases the tension on the control rope, and the duckbill closes quickly under the action of the spring.

[0024] The seedling tray fixing frame 41 of the seedling feeding mechanism 4 is fixed to the frame 1 by a column, located above the swing trajectory of the planting lifting rod 32. A bearing seat is provided in its center to mount the drive shaft 422. The rotating seedling tray 42 consists of the drive shaft 422 and multiple radially distributed seedling boxes 421 welded to it.Figure 4 As shown, each seedling box 421 is an open-bottom box, with its opening and closing bottom plate 4211 mounted on one side of the box via a torsion spring hinge, allowing it to open downwards in one direction. The seedling tray transmission mechanism 43 can be implemented using an intermittent mechanism (such as a Geneva mechanism) or an electromagnetic clutch in conjunction with an incomplete gear. Its power input is linked to the crankshaft of the planting drive mechanism 31 (e.g., via a chain). The linkage point is set as follows: when the crank rotates to the phase corresponding to the highest point of the planting lifting lever 32, the seedling tray transmission mechanism 43 is triggered to operate once, driving the transmission shaft 422 to rotate 360° / N degrees (N is the number of seedling boxes). At this time, the seedling box 421 that has just moved to the seedling opening 411 of the seedling tray fixing frame 41 loses the support of the bottom annular retaining edge of the seedling tray fixing frame 41, and springs downwards under the action of the torsion spring or the weight of the seedling, allowing the seedling to fall into the seedling receiving frame 331 of the planting device 33, which is at the highest point below. Subsequently, the rotating seedling tray 42 continues to rotate, and the seedling box 421 leaves the seedling inlet 411 area. The edge of its bottom plate 4211 is pushed upward by the annular retaining edge of the seedling tray fixing frame 41 and closes again.

[0025] The water tank 51 of the irrigation mechanism 5 is mounted on the water tank bracket 15. The pressure pump 52 is submerged in the water tank 51, and its power cord is connected to the battery of the traction vehicle. The spring-loaded closed irrigation valve 54 is a normally closed solenoid valve or a mechanical spring valve, fixed to the frame 1 by the bracket, and located on the extension line behind the movement trajectory of the seedling planter 33, with a distance L between them equal to the set plant spacing. The valve port tension rope 55 connects the mechanical opening rod of the valve to a cam (i.e., the brake 431) on the output shaft of the seedling tray transmission mechanism 43. By adjusting the angle of the cam, when the seedling planter 33 moves to the lowest point to open the hole for planting, the highest point of the cam just presses against the valve port tension rope 55, opening the valve for irrigation. The target point for irrigation is the seedling planted in the previous cycle, located at a distance L behind the seedling planter 33. When the cam rotates past the highest point, the valve closes.

[0026] During operation, the tractor pulls the entire machine forward at a constant speed. Power is transmitted through the transmission mechanism 2 to drive the planting drive mechanism 31, causing the seedling planter 33 to rise and fall periodically. Every time the machine travels a certain distance (determined by the travel speed and the planting drive frequency), the seedling planter 33 falls once, opening its beak to insert into the soil and create a pit. At the same time, the seedling feeding mechanism 4 completes one feeding, and the seedling falls into the seedling receiving frame. Subsequently, the seedling planter 33 rises with the seedling, the beak opens to leave the seedling in the pit, and the soil covering mechanism (which can be a simple scraper, not shown in the figure) or the traveling wheels naturally cover the soil. Simultaneously, the irrigation mechanism 5 waters the previous seedling. This cycle repeats continuously, achieving fully automated planting.

[0027] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
